How to Install Samsung SM-J810GF Firmware Flash File.
By August 9, 2020 Here’s what you need to download the official Samsung SM-J810GF firmware flash file onto your computer.
You can then use one of the compatible flashing tools to update the firmware on your smartphone or tablet.
Flashing tools were initially developed by the companies that were associated with the device’s hardware, kept in-house, used in the back rooms of smartphone repair centers to fix common mobile device-related problems.
The tools were later published on the Web for anyone to use.
Now you can solve the same kinds of issues that were once left up to those repair centers: bootloops, soft-brick situations, software errors, software bugs, update errors, so forth, by downloading the software onto your computer at home instead.
What’s more, installing the Samsung SM-J810GF flash file is an easy task, thanks to the flashing tool’s user-friendly interfaces that usually require just one click before the flashing is underway.
Most third-party developers who create tools for helping you customize your devices—the teams that work on custom recovery images, rooting applications, et cetera—recommend sticking with custom software if you have already changed the system partition or replaced the stock recovery partition with a custom one.

If you are to go back to stock Android on the device

though, they strongly suggest flashing the firmware yourself instead of accepting the over-the-air updates.
This is because OTAs can create unexpected behavior since they are often only patching over existing software instead of completely replacing it.

The flashing tools such as the Odin Flash Tool are always computer applications

On most occasions, these apps are relatively small files and will not take up much hard drive space.
You can sometimes have a choice of what flashing tool you want to use to flash the Samsung SM-J810GF stock firmware file.
You can flash stock ROMs with tools that work for either the system chip found in the device’s hardware, the firmware file type, or on occasion, apps that are designed to work for a particular manufacturer.
What Is Android Firmware?.
Firmware is the operating system and its applications that control how the smartphone or tablet that runs on Android operates.
While you may see the words “software update available” on your device’s display, we call it firmware to highlight its close relationship with the device manufacturers hardware.
If you prefer technical jargon, firmware is the specific programming that gets written to a device’s non-volatile memory.
The firmware gets added to the device during the manufacturing process and is the middleman in helping software run on the hardware.
Firmware can be written as read-only memory (ROM), erasable programmable read-only memory (EPROM), or flash memory.

The Android operating system is more open than much of its competitors in iOS

Windows 10 Mobile, and Tizen.
You always get firmware running on your device out of the box, but if you do not like it, you can swap it over with custom firmware or other firmware versions that were made for your device.
This flexibility helps with troubleshooting, .

Or if you know you would prefer a different Android version that was made available

Why Reinstall Stock Firmware?.
Did you think you may need to restore the stock firmware on your device.
Here are some of the things that you can achieve with stock firmware files: Upgrade or downgrade the version of Android on your device.
Fix common mobile device-related problems, such as unbearable bugs in the software.
Remove custom recovery images such as TWRP.

Unroot the Android operating system

regardless of what method/tool you may have used to get root access.
Unbrick your smartphone or tablet.
Reinstall the operating system.
Fix invalid IMEI problems.

Samsung SM-J810GF Firmware Flash File Download Links

The firmware can be downloaded directly onto a computer.
After extracting the file, you can then upload it to a flashing tool that is also on the computer.
Here is where you can download the firmware file: File Name: SM-J810GF_J810GFDDU3BSI4.zip Firmware File: Download flash file Flashing Instructions: You can use the Odin Flash Tool to install this version of the firmware file.

How to Install Samsung SM-J810GF Flash File Using Odin Flash Tool

To install the Samsung SM-J810GF firmware, you need to use a flashing tool that works for your manufacturer and run it on a computer.

One flashing tool that works for this smartphone is the Odin Flash Tool

Here is how to use it: Notes: Back Up Your Data.
You should always back up your data before you begin flashing new firmware files to your smartphone or tablet.
All your pictures, music, videos, documents, etc.
should be still on your device after you have updated the firmware, but you may need to restore the contacts and applications from a backup.
Wipe Cache and Factory Reset. Some people claim that taking a factory reset isn’t necessary after updates, but at the very least you should wipe the system cache after installing new firmware.
This way you can help eliminate any performance issues and battery draining bugs.
Taking a factory reset is the best way of avoiding common problems many users face after applying software updates.
The Odin flashing tool is straightforward to use, but it only works on the Windows operating system.
You won’t get the flashing tool to load on a Mac or Linux computer.
It doesn’t matter what version of the Windows operating system that you’re using as long as it is something above Windows XP.
The guide below works if your firmware file contains the tar.md5 file.
If you ever need to flash Samsung firmware using the full stock ROM files individually instead, you can learn how to flash Samsung stock firmware using all four files.
(Check your firmware file after you download it to see if it is a tar.md5 or comes as 4 individual files.).
Before We Begin.
Make sure you have: A desktop computer or laptop that is running on a version of the Windows operating system (ideally Windows 10 but at least Windows 7).
A USB data cable that allows you to connect your smartphone or tablet to the computer.
The tar.md5 file/files you want to flash to the smartphone or tablet.
You need to install USB drivers on the computer that allows for your smartphone or tablet to connect with the flashing tool.
Several drivers can achieve this.
If the drivers in the tutorial do not work for your device, try getting in contact with your smartphone’s manufacturer via an official website or phone number.
We recommend backing up the smartphone or tablet before getting started.

The Odin Flashing Tool is a reliable tool

but whenever you are installing firmware—regardless of the tool—it is possible you may want to restore the old version of your device.
You can only do that from a backup.

You need to download a version of the Odin Flash Tool during the tutorial

You should always download the latest version of the tool.
If that version does not work, try using an older version.
Latest versions of tools have the best chance of being compatible.
1.
Download the Samsung USB drivers and install them on the computer if you do not have them already.
2.
Download the stock firmware package from the links above directly to the computer.
Extract the file by right-clicking on it and choosing the option to extract.
When you do, you will see the tar.md5 file inside.
That’s the file you will be using to do the flashing.
3.
Download the Odin Flashing Tool.
Any version should work, but the latest is the most up to date so grab that one.
Extract the Odin file and then double-click on the Odin executable file (.exe) that is found from within the Odin folder after extraction.
You should now have the Odin interface open on the computer and waiting for you to connect to it.
4.
Boot the mobile device into the Download Mode by first powering it down and then rebooting by holding the Volume Down + Home + Power keys at the same time.
5.
A yellow warning triangle will come up on the device’s display.
At this time you need to press the Volume Up button.
You will then see the device getting into the download mode.
It’s then ready for the flashing.
6.
When in download mode, connect the Samsung mobile device to the computer with the USB cable.
7.
If you have installed the USB drivers correctly, the Odin flashing tool should detect your device.
You can tell this by observing the ID: COM port lighting up with a color, usually yellow or blue.
It does not matter what color, it is the lighting up that counts.
Some version of Odin will light up Blue while others will show yellow instead.
But the both signify the same thing which is your device is connected properly and ready for flashing.
8.
After the device is picked up by Odin, click on the PDA or AP button, depending on what button your version of the Odin flashing tool has.
9.
Navigate to the firmware folder and upload the tar.md5 file to this location in Odin.
10.
Without changing any of the default settings.

Click on the Start button in Odin

and the flashing then begins.
11.
Wait until Odin shows a Pass message before disconnecting your device.
12.
Your smartphone may now be in a boot loop, which will be fixed by booting the device into its stock Recovery mode.
13.
Press and Hold the Volume Up + Home + Power buttons simultaneously.
When you can feel the smartphone vibrate, release the Power button while continuing to hold down the Volume Up and Home buttons.
14.
You should now be in recovery mode.
From the Recovery menu, select Wipe data/factory reset.
15.
Wait for the cache to be cleared and then choose the Reboot system now option from the Recovery menu.
16.
The smartphone will reboot, and you will see the Android operating system ready to go.
That’s all.
How to Unroot Samsung SM-J810GF When Installing New Firmware.
There can often be a variety of ways to unroot a device that runs Android, and they depend on what method you used to get root access.
If you installed SuperSU for root access, then you can open the app and find the option to unroot directly from SuperSU’s settings.
On the other hand, if you do not have SuperSU, and you do have a Samsung smartphone or tablet, then you can always unroot by installing the stock firmware.
Once you have followed the guide above, your device will automatically be unrooted.
You can verify that is the case by installing one of the many applications from Google Play that checks for root access.
As long as you are using a reliable app, then typically it will not lie about the root status of your mobile device.

How to Go Back to Stock Recovery on Samsung SM-J810GF When Installing New Firmware

One of the most common reasons for installing the stock firmware is to remove a custom recovery image and go back to the stock recovery.
There is nothing you need to do extra to make your device go back to the stock recovery; when you install the stock firmware, it will automatically install the stock recovery partition on the device once again.
Additional Firmware.
You can download Android firmware for other Android devices if you have another smartphone or tablet from a different manufacturer.

usb 1 Comment on USB Inrush Testing

Tag: ChipWhisperer-Lite.
USB Inrush Testing.

The USB spec has limits on the ‘inrush current’

which is designed to prevent you from having 2000uF of capacitance that must be suddenly charged when your board is plugged into the USB port.
The limit works out to around 10uF of capacitance.
Your board might have much much more – so you’ll have to switch portions of your board on later with FETs as a soft-start.
For the ChipWhisperer-Lite, I naturally switch the FPGA + analog circuitry as to meet the 2.5 mA suspend current.

Thus I only have to ensure the 3.3V supply for the SAM3U2C meets the inrush limits

which is a fairly easy task.
This blog post describes how I did this testing.
The official USB Test Specs for inrush current testing describe the use of the Tektronix TCP202 which is $2000, and I don’t think I’d use again a lot.
Thus I’m describing my cheaper/easier method.
First.

I used a differential probe (part of the ChipWhisperer project

so you can see schematics) to measure the current across a 0.22 ohm shunt resistor.
The value was selected as I happened to have one around… you might want a smaller value (0.1 ohm say) even, as the voltage drop across this will reduce the voltage to your device.
The differential probe has enough gain to give your scope a fairly clean signal.
This shows my test board, where the differential probe is plugged into a simple 2-pin header: From the bottom, you can see where I cut the USB shield to bring the +5V line through the shunt: To calibrate the shunt + gain from the diff-probe, I just used some test loads, where I measure the current flowing through them with a DMM.
You can then figure out the equation for converting the scope measurement to a current in amps.
Finally, we plug in our actual board.

Here I’ve plugged in the ChipWhisperer-Lite prototype

The following figure shows the measurement after I’ve used a math channel in PicoScope to convert the voltage to a current measurement, and I’ve annotated where some of these spikes come from: Saving the data, .

We can run through the USB Electrical Analysis Tool 2.0 to get a test result

The USB-IF tool assumes your scope saves the files with time in seconds and current in amps.

The PicoScope .csv files have time in miliseconds

so you need to import the file into Excel, divide the column by 1000, and save the file again.

Finally you should get something like this: Note the inrush charge is > 50mC

but there is an automatic waiver for anything < 150 mC. While the system would be OK due to the waiver, I would prefer to avoid exceeding the 50 mC limit. In this case there’s an easy solution – I can delay the USB enumeration slightly from processor power-on, which limits the inrush to only the charging of the capacitors (which is done by ~15mS). This results in about 47 mC. This means I’ve got about 100 mC of headroom before I exceed the official limits. This extra headroom is needed in case of differences due to my use of the shunt for example. In addition, I should be adjusting the soft-start FET gate resistor to reduce the size of that huge soft-start spike. Ideally the capacitor charging shouldn’t draw more than the 500mA I claim when I enumerate, so that’s a little out of spec as-is. If I don’t want to change hardware I could consider using PWM on the FET gate even… March 2, 2015March 3, 2015 ChipWhisperer-Lite, tutorial, usb 1 Comment on USB Inrush Testing.

chipKIT Pi and the Arduino Motor Control Shield

Tag: connectivity.

DC Motor Control using Raspberry Pi

chipKIT Pi and the Arduino Motor Control Shield.
Overview.
This post is intended to demonstrate compatibility of the chipKIT Pi with certain existing Arduino shields.
In the second part of this post, we will also demonstrate how to communicate with the chipKIT Pi over a simple I/O line on the Raspberry Pi®, from a terminal window, .

To control the Arduino™ shield connected to the chipKIT Pi

Hardware/Software Needed.

Raspberry Pi: http://www.raspberrypi.org/

chipKIT Pi:  http://www.element14.com/community/community/knode/dev_platforms_kits/element14_dev_kits/microchip-chipkit/chipkit_pi.
Arduino Motor Control Shield or other: http://arduino.cc/en/Main/ArduinoMotorShieldR3.
Procedure.
Let’s begin by simply controlling a common Arduino shield.
NOTE: Always check the electrical characteristics of any shield that will be connected to the chipKIT Pi.
As with the Raspberry Pi, this is a 3.3V system.
Therefore, if a shield outputs voltages greater than 3.3V there is a possibility that you could damage the chipKIT Pi or the Raspberry Pi.

Connect the Arduino Motor Control Shield as shown: Start a new sketch in MPIDE

We will be using Brian Schmalz’s SoftPWMServo library for this application.
This is a very flexible library that will enable a PWM (square wave) output on any pin we like.
This library comes already included as a core library with the MPIDE.
Therefore, to use, simply add the header file to the library at the top of your sketch as follows: #include .
The remainder of the sketch follows set up as per the Arduino Motor Control Shield specifications.
I’ve added comments to explain each line of code.
//Include the SoftPWMServo Library #include void setup() { //set up channel B on the Arduino Motor Control Shield pinMode(13.

OUTPUT); //Pin 13 controls direction pinMode(8

OUTPUT); //Pin 8 controls the brake } void loop() { //Turn the motor // First we disengage the brake for Channel B digitalWrite(8,LOW); //Depending on how your motor leads are connected to the Arduino //motor B header, the direction could be clockwise or counter clockwise //So let”s just start by calling this direct 1 and drive pin 13 HIGH digitalWrite(13,HIGH); //We need to send a PWM to the Arduino MC shield to start the motor //turning.
We also define a duty cycle that will set the motor speed.
//The higher the duty cycle, the faster the motor will turn.
Duty cycle //is set between 0 and 255.
//So we send the PWM to pin 11 according to the Arduino MC specs at say // a duty cycle of 100 SoftPWMServoPWMWrite(11, 100); //Let”s run the motor for about 5 seconds delay(5000); //Now lets brake the motor digitalWrite(8,HIGH); //Give the motor a chance to settle delay(500); //change directions digitalWrite(13,LOW); //and run the motor for about 5seconds in the other direction delay(5000); //Again, we brake the motor digitalWrite(8,HIGH); //give the motor a chance to settle delay(500); //and repeat } So, this is nothing really special and can be done on any chipKIT Board.
However, we can make something pretty interesting by introducing some Python-based communication from the Raspberry Pi to the PIC32 MCU on the chipKIT Pi.

Raspberry pi robot USB Bootloader

The PIC32-avrdude-bootloader communicates over either a serial port (UART) or the USB port (on those pic32 chips that support USB.)  It can be built for either serial or USB communication with the PC.
The bootloader communicates with the avrdude executable on the PC side of the connection.
The following boards have been tested using the PIC32-avrdude-bootloader: Microchip PIC32 USB starter kit.
Microchip PIC32 Ethernet starter kit.
UBW32 – MX460.
UBW32 – MX795.
Fubarino SD.
Fubarino Mini.
In order to use this bootloader, you can either download the full source from github, or just pick and choose the HEX file that is right for your board.
There are three bootloaders that have been created for chipKIT and chipKIT compatible boards: PIC32-avrdude-bootloader – This new bootloader for MPIDE/chipKIT PIC32 boards is buildable for all currently available  chipKIT boards (UNO32, MAX32, uC32) as well as other PIC32 based boards like the UBW32 and Fubarino boards.
pic32-Arduino-USB-Bootloader-original – This is the original version of the bootloader that works only if compiled with the C32 v1.xx version due to changes in the way that newer version of C32/XC32 handles the linker scripts files.
pic32-Arduino-Bootloader – This is the older original version of the bootloader which supports only Digilent uno and mega pic32 boards.
This bootloader is compatible with v5.8 of avrdude.
For Digilent pic32 boards, it is highly recommended to download the Digilent official bootloader from the Digilent website at http://www.digilentinc.com/.

Connectivity Using USB

The PIC32MX3xx series parts do not have a USB controller

The other PIC32 series (i.e.

PIC32MX4xx/5xx/6xx/7xx) all have a USB controller

The Uno32 uses a PIC32MX320F128H and therefore does not have a USB controller

The Uno32 and Max32 have standard FTDI serial to USB interface chips (FT232R) to keep consistent with the Arduino way of interfacing.
However, .

It is also nice to be able to use the built in USB port

Many other PIC32 boards have this USB port brought out to a standard connector such as the Microchip USB Starter Kit and the Digilent Cerebot 32MX4 and Cerebot 32MX7.
The latest version of HardwareSerial.cpp now supports the first serial port (Serial.begin(), .

Serial.print() etc) can be reconfigured to use the USB port instead

In order to take full advantage of this, first you have to program the board with the USB bootloader, then use the appropriate board setting in the BOARDS menu.
If you are using a custom board in the boards file you can just add the following to your board description: custom_pic32.compiler.define=-D_USE_USB_FOR_SERIAL_ When using the USB for Serial, UART1 becomes Serial0 Serial1 etc, are still there normal configurations Serial.begin(baudrate); //The baudrate is ignored, when doing real USB, there is no baudrate.
Receive is interrupt driven and behaves EXACTLY like regular Serial.
NO CODE CHANGES REQUIRED.
If you want to see how this is done, look at HardwareSerial.h and HardwareSerial.cpp, the actual usb code is in HardwareSerial_cdcacm.c and HardwareSerial_usb.c.
The USB code was written by Rich T (http://www.cpustick.com/) More documentation will be provided on how to do this soon.
