I have a rooted sprint galaxy S4 SPL-L720 with build version L720VPUFNG2. I need to change it to L720VPUAMDC build. I already have the tar file downloaded. for MDC.

Make sure that Samsung KIES is comleptely disabled or uninstalled.
Connect your phone in "DOWNLOAD" mode (Power off, then press "Vol down + home + power" at the same time)
Run ODIN and select the downloaded firmware (.tar.md5 file) as "AP"
Press start and wait about 15 minutes for ODIN finishing the installtion.
All of your personal data may be deleted when installing firmware using ODIN (Depends on phone and firmware)

after odin finishes do i need to volumn up to apply update or will changes occur when it auto boots? Many thanks

[Q] Another firmware question

I bought a US refurb P6210, I am in the UK.
Using Kies it doesn't state a current firmware version - is that a problem?
It also states there are no updates available - fine if true, not needing one.
How do I know what software I am using so I can get a Stock image for recovery purposes?
Android Version: 3.2
Kernel: 2.6.36-P6210UEKJC-CL567728
Build: HTJ85B.UEKJC.P6210UEKJC
Which doesn't seem to tie up with any of these:

It looks like I have a North American firmware October 2011 version C
The guy below me has European firmware Dec 2011 version 4
I too seem to have an unknown Firmware
Model: Gt-P6210
Android: 3.2
Kernel: 2.6.36-P6210XXKL4-CL604657
[email protected]#3
Build Number: HTJ85B.XXKL4 P6210XXKL4
UEKJC to UEKL1
Has anyone succesfully flashed the full P6210UEKL1 package over the P6210UEKJC firmware?
I'm starting to think UEKJC is a very early or slightly unofficial firmware as Kies doesn't recognise it (Current firmware version: BLANK) and the OTA never finds any updates.
This seems to be the firmware coming on the US refurb units from Digigood on eBay.
I'm tempted to start from fresh and flash UEKL1 using Odin and then see if Kies and OTA start to pick up the real updates from there.
For Odin flashing would this be the right process?
1. Start Odin 1.85
2. Load P6210XARKL1_P6210UEKL1_HOME.tar.md5 into PDA section
3. Turn on P6210 with Power and Volume Down and choose Download mode
4. Hit Start on Odin
Any advice/help appreciated

Yup. That's the correct process. This should bring you back to stock. I don't know what's been done to your tab's ROM in order for KIES not to recognize it, (I'd probably need more information, but it's not at all important,) this process should give you a clean slate from which to start. Good luck!

Best Root Method for G920F

Hello,
Noob Q here. What is the best/safest root method and install custom recovery(TWRP) for my G920F from Philippines thats still running 6.0.1 ,CSC-xte ,network SUN but already openline both sim slot. And which rom you guys recommend installing that would work for dual sim S6. Because it seems Samsung has abandon the update to android N for this specific variant or CSC. . By the way , ones the phone is rooted , can i just flash any Nougat ROMs for G920F even if coming from MM ? Thanks in advance and any information is highly appreciated.
I think you want to upgrade device to N, that's why you want to root, right?
If so, just upgrade it via Odin without tripping Knox and wiping your data.
Every SM-G920F ROM has compatibility with dual SIM model.

Yes ,you are right on the dot. Just want to upgrade to N. But i have no idea which firmware to use that would work properly for my S6 . And from my experience with older Samsung devices , they seem to work way better if i do use custom samsung base ROM. So im at the part were im still contemplating if i should root and use custom rom or upgrade it with stock N firmware using ODIN that might work well with my S6 ,cause i know there is
no N firmware yet for my CSC (XTE). At the moment , i do not have any other back up phone that i can use in case my S6 goes soft brick. Thank you so much for the suggestion , and your actually the second person that said to just upgrade it through ODIN , so i might just do that. Just need to find out which one to use exactly.

G930F locked on Combination firmware

Hi guys
I need a helping hand.
I have a s7 (G930F fxxu2drb6) with frp lock.
It did not work either realterm, bluetooth, or downgrade (SW REV CHECK FAIL DEVICE 2, BINARY 1 SAMSUNG).

After the flash I can not yet downgrade (W REV CHECK FAIL DEVICE 2, BINARY 1 SAMSUNG), not even flash again "fxxu2drb6" (FAIL RQT_close).

Hello. I have a similar problem. I have the latest firmware on it: G930FXXS2DRDI There are no ways to lift the Google lock. I have tried everything possible: Bluetooth does not work, Talkback, Realterm, etc. Please for help

Hello my friend, i have this problem too. Have you a fix? this security patch for FRP is incredible....
You CAN bypass FRP on later Samsung models using Combination FW. I have succsesfully done this with S8+/G955F, it should work with any device that has compatible Stock/Combinaton FW.. Here are the steps. Download a compatible STOCK ROM, and some similar COMBINATION FW (by similar i mean both FW to be with the same binary and same android version, duh..) Here are some firmware download links, but you can use whatever you want, according to your device.. G930F STOCK ROM/G930F Combination FW
First, using Odin flash the COMBINATION FW to your phone. After flashing is complete and the phone reboots, allow a few minutes for the phone to boot. If it doesn't boot/gets stuck at bootlogo, reboot/boot to recovery and wipe data/cache, and reboot again. MOST IMPORTANT THING! After the phone boots, go to Settings, enable Developer Options if not enabled, enable USB Debugging, and turn the device OFF using Power button. After the device shuts down, enter Download mode, open Odin, place all 4 files in their respective fields (BL,AP,CP,CSC), and here is the SECOND MOST IMPORTANT THING! In the CSC field place the CSC file that starts with HOME/HOME_CSC (There will/should be 2 different CSC files in the FW archive, one starting with CSC, and the other with HOME_CSC). After flashing is complete, allow the phone to boot normally (don't do anything, don't enter recovery/wipe data). If you followed my instructions correctly, after the phone boots, you should be able to finish the initial setup/skip all steps, without requiring any account. Then go to Settings, enable Developer Options, turn OEM Unlock ON, and finally factory reset the device to complete the process and start fresh.
Don't forget to hit THANKS button if this method worked fo you!
ATRAC3, do you have the combination files and firmware for the SAMSUNG S7 SM-G930FD please and thank you for your wonderful tutorial here.
my odin(tried on v3.12.5/v3.12.7/v3.13.1 ) keep failing while flashing HOME_CSC but will success with CSC, and still required to login google account, what is the issue here ? (are we supposed to insert the pit file by ATRAC3 ? )

Hi mate ive used the G930FXXU2DRBE XSA Firmware and also G930FXXU2DRB6 firmware with the G930FXXU2ARA2 combination rom however it will not boot past the samsung logo the nad passes and is provisioned in top left corner and when plugged into the computer comes online with ADB bypass flasher but it just sits there even if i do a cache wipe and factory reset it comes up with a tango console error or something like that when reset then reboots back to samsung logo and when re installing firmware HOME-CSC will fail every time the only thing ive been able to put it down to is that (1) the firmware is FA_70 which is nougat OS and the combination rom is FA_60 MM or (2) my knox warranty bit is tripped and will not allow a samsung factory binary to be run on it, may i ask what would be the difference with the firmware you have listed to the firmware im already using with the combination rom ? Need to sort my imei number out with the factory nad asap dont have access to my TWRP backup for another week and a half, if it helps my device is not FRP locked and is oem unlocked.
Thanks
Matthew
P.S to all those whom have a bit 2 bootloader on S7 all the loopholes have been patched the only way is to use the combination files ive been through absolutely everything and tried everything this new bootloader update is impenetrable i can google unlock samsung S8 and S9 no dramas and with S9 the OEM lock option dissapears for a week if tampered with but still 15 minutes and its done this **** but got me goin loco holmes !!!!! Maybe they figured this out also as there is only bit 1 bootloaders for both the S8 and the S9 however with S8 i found a stock firmware that allows another way to unlock the device without the need to flash any combination rom.
So in short no hope now to unbrick our Samsung S7 SM-G930F/FD or what.....?

If it gets stuck on the console error and wont reboot to download mode then hold the power button volume down button and power button for 40 seconds and it will re boot to download mode for stock firmware re installation in short basically no theres way to remove the FRP unless you can get the combination rom to boot which from what ive seen some will boot the binary but then it also depends if HOME_CSC will flash to keep usb debugging enabled to use adb bypass program im now using the new G930FXXU2ERE2 8.0 OREO so I've given up on the binary 2 nougat FRP unlocking for now might be best to wait a while for someone to receive a factory binary on the nougat or oreo when sent off and returned so it can be dumped and built into a flashable rom until then not much can be done and i may have to wait another week and a half for my EFS backup :'(
We will be waiting from u for the new combination file when out bro, our hope are hinged on u!
No one is coming up with any method about the bootloader binary 2 for the Samsung S7 G930FD...?

[Guide] How to downgrade from Android Oreo 8.0 to 7.0 (Non-rooted)

How to downgrade a non-rooted S7 Edge from Android Oreo 8.0 to 7.0 and keeping your Knox 0x0!
So if some of you are looking for a 'how-to' guide, look no further! ​(I believe it works on your S7 too, but make sure you have downloaded the correct firmware)​
*IMPORTANT*
-I don't take ANY responsibility if you bricked your device during the flash!
-Follow the guide below before flashing your official firmware using Odin!
On the phone
-Sign-out any accounts on settings
-Have OEM-unlock & USB Debugging ON (developer options)
-*optional task, just in case* Screenshot your device information on the settings tab (IMEI, Baseband, Software Info, Model number)
-*optional task, just in case* Backup your device using Samsung SmartSwitch software
Things to download
-For this guide I used Odin v3.13.1 https://dl.sammobile.com/Odin3-v3.13.1.zip
-You can install the Samsung driver using SmartSwitch if your Win PC can't detect your Samsung phone (it should show on Device Manager > Modem > something like Samsung Modem)
-*READ* You can't flash back to version 6.0 now because of (Android Oreo 8.0 is using different version of boot-loader) but there are some late Android 7.0 with updated boot-loader, those are using boot-loader binary v2, so binary v1 it will be conflicted and won't work upon flash.
-*NOTE* Download the correct firmware of your phone model by following the baseband, that's why I recommended to take screenshots of your phone, you can search it on here https://www.sammobile.com/firmwares/, for mine, I've searched SM-G935F and BTU is my choice, the filtered results should be your correct firmware. But in my case I used (v7.0 in March 2018) because it has the binary boot-loader v2 with it (whatever it called, it's important otherwise it will not work which I've tried)
-*optional*, if you find sammobile download speed is way too slow* You can use https://updato.com/firmware-archive-select-model?q=SM-G935F&exact=1&r=&v=Nougat%28Android+7.0%29%2COreo%28Android+8.0.0%29&rpp=100, and basically look for the correct firmware which I have mentioned above.
-Extract your firmware onto a single folder, don't mess them up! (you should see something like AP_G935blahblahblah.md5, and you will need AP_, BL_, CP_, CSC_ for downgrading)
Follow the steps:
1. Now you have the correct firmware and Odin running on Admin right
2. On Odin you can add AP_, BL_, CP_ & CSC_ onto the correct selection, for example: https://i.imgur.com/DIB2d1S.png
3. Have your phone on Download mode, google it if you don't know how (make sure you followed the On the phone step first, it's very important)
4. Find a data USB cable and plug into USB2.0 port, make sure your phone appeared on Odin (you will see something like 0:[COM5])
5. On Odin (only Auto Reboot, F. Reset Time) is needed, it should be ticked by default.
6. Now you can safely click 'Start' on Odin.
7. DO NOT TOUCH YOUR PHONE in case your USB is loose which I had experience before.
8. Wait until it shows a green PASS! like this: https://i.imgur.com/FYosmx2.png
9. When see a blue screen with Erasing text on it, please wait until it reboot and hold (Volume UP + Home Button + Power Button) boot to recovery mode
10. Wipe cache partition, and data/factory reset then reboot system now
11. Wait for it to boot into your sweet sweet Android Nougat 7.0 (Late version)
12. Disable auto-update if you wish, mine was on auto-update so I had to pause it half-way
Hope you find this guide helpful, I tried to remember the steps on my head as I typed, (*sorry for the grammar if you find it hard to understand) and if you think I've missed something here, let me know! I would update the guide if any step is missing, just in case
Thanks

I tried but doesn't work
Hello dear!
I have a S7 edge SM-G935T and I tried to flash the last version of Nougat 7, but doesn't work. Odin don't let me finish the process. Maybe you wrote this thread before my cellphone received the last update of Oreo.
Do you have any solution in this case. I really appreciate it.
King regards, _/\_

Help with G930A
Hello um I have a Samsung Galaxy S7 on AT&T (G939A) and it's on 8.0 (G930AUCS9CSB1). I've tried to root it but after some research I've come to find out I have to downgrade it to nougat to root it. But the problem is everytime I load a firmware it fails and I did more research I think it said something about the bootloader blocking it and the only way to downgrade the bootloader is downgrading the firmware which I can't do because of that cycle. Can someone please help me all I want to do is root install a custom recovery and a custom rom I love playing around with android tweaks but I can't get it because of this. I hope someone can help me please and thank you.

Your bootloader cannot be unlocked due to it being Snapdragon, so unfortunately there is nothing you can do. Only Exynos variants can be modified.
Hello guys,I have a problem with my galaxy s7 sm-g935f(Exynos version).Few months ago I flashed my phone from android Nougat SEE CSC(South East Europe) to UK's Oreo BTU CSC.I'm curious is there any other way to downgrade it from oreo to nougat,otherwise than Odin.I tried flashing it a few times with the latest Odin version (3.13.3) and nougat SEE CSC(South East Europe) because that's my original CSC.Odin recognizes the device normally,but when i click start,it comes to setup connection and then FAIL.The reason I'm trying to downgrade is very poor battery life and heating,and the phone is very laggy.I even tried through Samsung Smart Switch Emergency software recovery but it seems that Samsung has restricted that option...please help if anyone has/had similar problem.Thank you!
Mine is Sprint g935pvpsbcta1
Am I screwed also?
Hi, I have
SM-G935F​and I can't find any nougat firmware with baseband of: G935FXXS8ETCA.. Can I flash any country / baseband 7.0 firmware? And will it improve the SOT? I'm currently getting upto 5 hours SOT.

How to downgrade a non-rooted S7 Edge from Android Oreo 8.0 to 7.0 and keeping your Knox 0x0!
So if some of you are looking for a 'how-to' guide, look no further!
(I believe it works on your S7 too, but make sure you have downloaded the correct firmware)​
*IMPORTANT*
-I don't take ANY responsibility if you bricked your device during the flash!
-Follow the guide below before flashing your official firmware using Odin!
On the phone
-Sign-out any accounts on settings
-Have OEM-unlock & USB Debugging ON (developer options)
-*optional task, just in case* Screenshot your device information on the settings tab (IMEI, Baseband, Software Info, Model number)
-*optional task, just in case* Backup your device using Samsung SmartSwitch software
Things to download
-For this guide I used Odin v3.13.1 https://dl.sammobile.com/Odin3-v3.13.1.zip
-You can install the Samsung driver using SmartSwitch if your Win PC can't detect your Samsung phone (it should show on Device Manager > Modem > something like Samsung Modem)
-*READ* You can't flash back to version 6.0 now because of (Android Oreo 8.0 is using different version of boot-loader) but there are some late Android 7.0 with updated boot-loader, those are using boot-loader binary v2, so binary v1 it will be conflicted and won't work upon flash.
-*NOTE* Download the correct firmware of your phone model by following the baseband, that's why I recommended to take screenshots of your phone, you can search it on here https://www.sammobile.com/firmwares/, for mine, I've searched SM-G935F and BTU is my choice, the filtered results should be your correct firmware. But in my case I used (v7.0 in March 2018) because it has the binary boot-loader v2 with it (whatever it called, it's important otherwise it will not work which I've tried)
-*optional*, if you find sammobile download speed is way too slow* You can use https://updato.com/firmware-archive-select-model?q=SM-G935F&exact=1&r=&v=Nougat%28Android+7.0%29%2COreo%28Android+8.0.0%29&rpp=100, and basically look for the correct firmware which I have mentioned above.
-Extract your firmware onto a single folder, don't mess them up! (you should see something like AP_G935blahblahblah.md5, and you will need AP_, BL_, CP_, CSC_ for downgrading)
Follow the steps:
1. Now you have the correct firmware and Odin running on Admin right
2. On Odin you can add AP_, BL_, CP_ & CSC_ onto the correct selection, for example:
https://imgur.com/DIB2d1S
3. Have your phone on Download mode, google it if you don't know how (make sure you followed the On the phone step first, it's very important)
4. Find a data USB cable and plug into USB2.0 port, make sure your phone appeared on Odin (you will see something like 0:[COM5])
5. On Odin (only Auto Reboot, F. Reset Time) is needed, it should be ticked by default.
6. Now you can safely click 'Start' on Odin.
7. DO NOT TOUCH YOUR PHONE in case your USB is loose which I had experience before.
8. Wait until it shows a green PASS! like this:
https://imgur.com/FYosmx2
9. When see a blue screen with Erasing text on it, please wait until it reboot and hold (Volume UP + Home Button + Power Button) boot to recovery mode
10. Wipe cache partition, and data/factory reset then reboot system now
11. Wait for it to boot into your sweet sweet Android Nougat 7.0 (Late version)
12. Disable auto-update if you wish, mine was on auto-update so I had to pause it half-way
Hope you find this guide helpful, I tried to remember the steps on my head as I typed, (*sorry for the grammar if you find it hard to understand) and if you think I've missed something here, let me know! I would update the guide if any step is missing, just in case

Since the j7 prime never recieved any bootloader upgrades it is possible to downgrade. I would suggest upgrading to oreo however,or maybe installing android 10 custom roms. anyway, to install stock 7/8 go to this link and enter your device model and country and download the latest stock firmware for you. then download odin . once you have both downloaded, unzip both of them, and open up odin. When you get you should see ap, bl, cp,csc . press the 4 buttons mentioned before and go to where you extracted the stock firmware, and you can select the appropriate file. Then boot your device to download mode by holding volume down, power and home button at the same time for 5-10 seconds. press continue. Then connect your phone to your pc, and press start in odin.

oreo is the latest official firmware recieved by this phone. There is no official android 10 rom for this phone. Yes you will likely lose all your data.

You can flash firmware of any county, since is for the exact same model you have (ex: SM-G610) there's no problem. But keep in mind some have bootlogo/apps from operator, and/or extra functionality s/bloatwares.
