Revert to 4.2.2 with device status official (warranty bit 1)

Hello friends I am on the latest Russian 4.3 firmware and am flashing the PIT and the old bootloader and then a stock 4.2.2 indian Firmware to check if the warranty bit can be reinstated !!!!!!!! Because here in India the service centers dont know or dont bother to check the hidden counter.......
I know I am taking a risk but opening this thread so that I can post my observations and maybe we can work something out.....fingers crossed!!!!!
UPDATE 1 : Was Unable to flash the MG1 bootloader getting failed on odin and unsupported !!!!!
UPDATE 2 : Flashed UBUBMH1 4.2.2 successfully no IMEI loss all working fine so yes we can downgrade to 4.2.2
The bootloader though remains unchanged and shows device status as custom!!!!!
UPDATE 3 : Flashed the leaked 4.3 and device status says official binary also official only warranty bit says 1
UPDATE 4 : Device is able to check for OTA updates and not given an error saying your device has been modified
**********************************************************************************
STEPS TO REVERT I9500 TO 4.2.2 WITH OFFICIAL STATUS
**********************************************************************************
1) Download South African FW 4.2.2 http://samsung-updates.com/details/14135/Galaxy_S_4_Exynos_Octa/GT-I9500/XFE/I9500XXUBMH1.html
2) Go to recovery wipe data factory reset and wipe cache and then flash the firmware that you downloaded above
NOTE : If you are on the russian 4.3 and having issues flashing this FW then first flash the leaked 4.3 from here
http://forum.xda-developers.com/showthread.php?t=2488155
3) After flashing leaked 4.3 go to settings and check device status it should say official
4)now go to download mode and flash the 4.2.2 rom you downloaded
5) NOTE : IF YOU ARE STILL HAVING TROUBLE GOING BACK TO 4.2.2 YOU CAN DOWNLOAD THE
ATTACHED PIT FILE AND FLASH IT ALONG WITH THE 4.2.2 ROM
IN ODIN SELECT THE PIT FILE IN PIT SECTION AND SELECT THE FW IN PDA SECTION
AS A LAST RESORT IF NOTHING WORKS THEN FOLLOW THE STEPS FROM STEP 1 AGAIN USING ODIN
1.85 attached below!!!!!!
PLEASE EXTRACT THE ODIN AND PIT FILES BEFORE USING.
Trying other things now!!!!!!!
I will be posting detailed steps with links soon!!!!!!!

Hey,
When I was in 4.2.2, root and kernels and Cwm were already flashed so my binary and system were custom. But when I flashed 4.3 leak all become official and warranty bit: 0, I was happy that I kept my warranty.
But now, my warranty bit is 1 because I flashed cf root. And downgrading to 4.2.2 and flashing again 4.3 didn't change anything. I really want to know how to remove that knox bootloader.

Well as the title states right now there is no way to do that its been three hrs i have tried all sorts of crazy things to go back to the old bootloader but it just refuses to flash so we will have to wait.....I created this thread so that at least we can have the binary and status official because most of the places that will be ok like in india if i go to the svc center and it says official all will be ok!!!!

hey @hypergamer1231,
what is the procedure to revert back to 4.2.2, am currently CF-Rooted on 4.3?
can you please tell me what all things are required ?(will be thankful if you provide the links)
and after that again upgrading to 4.3 will i be able to use Knox container app???
i don't have any problem with bit 1, just want to use container app !
Thanks in advance

Thks 4 this tutorial, Perfect in My S4 TTT Region.
Congrats Bro

Just got the official 4.3 OTA update (INS). Not going to update coz of warranty bit. It should be 0 when I update, but as soon as I root it would become 1. Will be waiting for AOSP or MIUI for i9500, say a month or so. Then will use it and update to 4.3 next yr (or maybe 4.4 then?) When warranty anyway would expire.
Edit - this is similar to Knox on i9505, hence even downgrading your official software doesn't remove the boot loader, and in fact triggers it.

i am not sure but thats a very good idea i would have tried that but i am already on the new bootloader if you can try that would be great make sure you have a nandroid backup and efs backup!!!!!! Do it at your own risk at the most u will have basic issues try and revert if poss

thank you,it works like a charme even if a had the russian 4.3, no need to go back to the indian version ,just used odin 1.85 with the.PIT and the south african 4.2.2

My experience:
My GT-I9505 was a Hongkong version with its stock firmware version I9505ZHUAME3, then OTA to ZHUDMI1.
After flashed the CWM recovery, the KNOX warranty set to 0x1. As you know, ZHUDMI1 cannot be fully rooted now.
Then I tried to flash the phone by ODIN with I9505ZHUBMF4 (includes PIT, PHONE, MODEM, CSC). The phone showed "OFFICIAL" and can OTA again, but I disabled auto upgrade.
And rooted the phone with CF-Auto-Root-jflte-jfltexx-gti9505. Now its status is "CUSTOM". Anyway, maybe I lost the warranty, but I can use this phone with fully rooted now.

I have nothing useful to add except that I find it funny that my country's firmware is allowing for downgrades :lol:. Congrats on finding the exploit BTW .

I learnt from the S2 days never, ever flash the latest leaks until a work around has been found. So yeah I have not gone the 4.3 route just yet but its nice to know that the firmware I already have could downgrade me should the need arise .

My experience:
So I have a I9500, and its on the russian 4.3, and I root it, it says both binary and status official except the Warranty Bit is 1, and Knox won't work on my phone, It goes " Your device is not authorised to enter knox mode". It shows the same thing after I unroot it ( Flash the 4.3 rom again). Just wonder is there any way that I can use Knox again??

Install the stock ROM via odin. It's solve the problem, try another ROM from another country.

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.

Stuck at Powered by Android please help SM-N915G

My Fried gave this phone to me (SM-N915G) which is stuck at Powered by Android, and told me to fix it.
He said that when he update to MM from LP without KIES or Odin, the phone suddenly restarted and stuck there getting HOT
He had no experiece to repair it so he asked me to fix it.
So for 3 days lately, i have tried many ways to fix it but wihout any progress, as follow :
1. Flashing Official MM wby using Odin -> still stuck
2. Downgrading Flash Official LP using Odin -> still stuck
3. Installed TWRP, and flasing CFW Micky387_MM_V3.0 for 915F/FY/G (flashing Bootloader and modem as required) -> still stuck with set warranty bit : kernel
4. After Flashing Micky CFW and Failde, i try to flash Emotion Kernel -> still stuck with Kernel is Seandroid Enforcing
5. Redoing Flash Micky CFW with other CSC -> Still Stuck (even i tried with 915F and 915FY as in the aroma installer)
6. Never failed during flash procedure with Odin or TWRP, everything is smooth
7. When stuck, the device is getting Hot slowly but and when left as long as 15 minutes, the HH is getting HOT (TWRP read 72 degree at most)
**Update
8. Tried using Official SmartSwitch sucessfully but the result is still the same -> Still Stuck and getting hot as usual T.T
Last Download Mode status is :
Odin Mode (High Speed)
Product name: SM-N915G
Current Binary: Samsung Official
System Status: Official
Reactivation Lock: Off
Knox warranty void: 0x1 (2)
Quallcomm secureboot : Enable (CSB)

I can tell you that Kies and NOT Kies 3 was what worked for me when I downloaded/installed Marshmallow from Samsung's website.
Figure that one out.
That was also using a 64 bit version of Windows 7 Pro.

I'm going to guess that you've tried installing MM using Kies directly from Sammobile?
If so,have you tried turning off your computer's antivirus when you download/install?
It sounds like the bootloader is looking for something and can't find it.....kind of like what happened to me when I totally ripped KNOX out of my phone.
Restore time!
Good thing I did CWM backups.
In your case,your computer's anti virus could be seeing something in the download and ripping it out.
I've seen my browsers do that when I download stuff....pain in the....
Have you tried a different battery?
Maybe a search of the forums to see if anyone else has had this problem and solved it?
I kind of remember seeing something like this a while back.

Thank you for the response,
I was using KIES 2.64 that downloaded from Samsung website to fix the phone as your suggestion (tools->firmware upgrade and initialisation) but still fail to fix it.
Nope, the antivirus still active when KIES download the FW and Flash it into the phone, but it is new to me that antivirus will intercept ongoing dowloaded files, if so i think the antivirus will give some notification or warning about the content of the file that being downloaded and in my case, my antivirus is still cool and no notification whatsoever.
The bad thing is i do not have any cwm backup and since this is my friend phone and not mine, well... we dont have any backup for this phone.
Regarding the battery, i admit that i havent try other battery, since i dont see any connecton between it, in my opinion, the phone works well, the charging animation working, and no sign of weak battery... but i will try to do it if i can get some other battery
I have surfed many forums and websites, but almost 90% can be fixed with simple flashing from odin or just by clearing up cache and data from recovery.
Other that that, wither, no one respond to the problem, or just some discussion without conclusion, really frustrating.
I even go further to read about android booting sequence to identify whats wrong with the boot sequence, but still confused...
But i have some question if you would to answer :
1 . Stuck at Android logo, bootloader or kernel problem?
2 . Is it possible that one of the mainboard chip that have some part in booting process is malfunctioning? But if so, the phone will be dead bricked right?
3. How about the booting process is halted due some hardware failure? ex : some chip (other than chip that have part in booting process) is bad and so the bootloader init is halted
4. The Worst guess, is it possible that the phone is fake? (the serial number behind the baterry is accepted by kies though)
Thank you very much, you are the only one who still response to my problem. :good:

As it seems you use the wrong Bootlaoder. Is his phone N915P or N915G? When you flash N915G Bootloader to N915P, it will not boot but the bootloader will work correctly. Try to flash the N915P bootloader.
I have N915FY phone but did not know first if I had N915F or FY. I flashed the N915F bootloader version, which flashed successfully, but was not booting. Bootloader said that my phones model is N915F. After flashing the FY Bootloader version, it successfully booted to system.

Thank you for the Response,
First, his phone is N915G (according to the box and the information in the battery compartment)
(Really sorry for the mistake i made at the thread title)
And regarding bootloader, that is also my concern at first, i think maybe i was flasing wrong region and bootloader, and so i search the way to find out the real version of the phone, but after trying many ways described on the net (by imei or serial number) , i still cannot found out the way.
But one instance when i try using KIES, and KIES asked for the version and serial number when device upgrade and initialisation, i entered the exact version and serial number that is found behind the phone in battery compartment. KIES immediately confirms that the version and serial number is valid, (i still wonder though, is KIES check it online at Samsung server or there are some serial number database embedded in the KIES) and continue to run trough the official fw download and installation by KIES but at the end still no success.
Is it possible that the version and serial number is wrong ? if so, how to determine the correct one?
and is it safe to try flasing another bootloader?
Thank you very much

Hello, there is no bootloader related to serial number or something. There are different bootloaders for different models and android version. When you flash MM-Version, you need to be sure that you use the right bootloader and baseband files for MM. If you flash different region-locked firmware/bootloader, it will not affect btw. not solve the boot-stuck problem.
http://samsung-updates.com/device/?id=SM-N915G Try to flash 6.0.1 firmware that is related to your region if you still want to try to flash different region-firmware.
Maybe download the XSA 6.0.1 Firmware with the pit file XSA http://gsm-firmware.com/index.php?a=browse&b=file-info&id=15892.
Then flash XSA 6.0.1 and TBLTE_SEA_XSA.pit together in odin. Under Odin 3 V3.12 ticke the re-partition at option-tab and select TBLTE_SEA_XSA.pit under pit-tab.

Thanks for the reply!
Although there is no bootloader related to serial number, but if we put the serial number in KIES, it will identify what CSC and region, which can be use as a guide to choose the correct FW or let KIES do the Flashing according to the inputted serial number, and as long as the serial number is correct one, that is my opinion but please CMIIW.
When flashing MM, if i use the MM that has been downloaded, the bootloader and baseband is included in the MM image right? or shouuld i flash it separately?
i have tried your suggestion but with no sucess, i have dowloaded the PIT and the FW, flash it trough odin which was sucess, but still stuck.
I do not tick auto restart at Odin, so i manually restart the phone, but i encounter an event which at 20% installing system update (below the greed droid guy) the progress bar is vanished and replaced with erasing, and after that the phone stuck again at the same spot.
Do you have any idea why?
Thank you very much.

Just thinking, should i erase the NAND in ODIN?
If so, how to restore it?
I think that if i backup the NAND using custom recovery and restore it later, it just bring back the same problem, if the NAND causing all this.
Do anyone have some NAND backup that i could use? or any other suggestion?
Thank you

Can you boot to recovery? if yes, try to wipe data and cache.
If it still not working, try to backup your efs with a custom recovery (ex. TWRP), or better the entire System like data, system, boot, efs, modem and save it to your computer.
After saving the backup, try to flash the firmware with pit file while checked NAND erase all.
When its finished and your device boots up, you can flash back your custom recovery and recover only the efs-partition.
If its not working, then there is maybe problems with your eMMC. But be aware using nand erase all. It is the last riskfully option left after trying several things.
I have a backup of my resurrection rom. If you want it I can upload it.

-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'm guessing Knox counter wouldn't have incremented?

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.

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.

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)​

-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

And i want to downgrade to 5.1.1 or 6.0 because 7.0 was really terrible.

[N915FY] About downgrading…

Hello,
I would like to downgrade a Galaxy Note Edge (N915FY) to Android Kitkat but I haven't done it in a few years. I wanted to make sure I understood everything before I made any mistakes. I saw on differents topics on XDA that Samsung was preventing to downgrade on their devices since android 5.0.1.
In this case :
Is reinstalling the bootloader of an Kitkat firmware with Odin is enough to reinstall an stock android 4.4 firmware after ?
Did you know where I can find an Android 4.4 bootloader for N915FY (can I extract it from the stock firmware) ?
Did I need to do and tick "Re-Partition" on Odin ?
If I do a re-partition, what PIT file should I use (see on sammobile.com) ? (TBLTE_EUR_OPENBTU_HIDDEN100M.pit or TBLTE_EUR_OPENBTU.pit)
What is the difference between SM-N915FY and SM-N915F, I understand that one was for the European market and the other for the international market (bootloader?, partition?, LTE frequency?) ?
Do any of you have a Kitkat full stock firmware (BL, AP, CP, CSC) region XEF ? I can't find any on Internet, all the links are dead.
Thanks a lot for your help
Feel free to answer me even if you only have part of the answer !

Hello,
Thanks for your answer, I finally left the phone with the latest version of marshmallow available. What surprises me is that I only saw positive opinions on the kitkat version, since the phone works pretty well so I thought it wasn't worth the risk of downgrading.
Maybe the bugs you had come from a problem with the memory chip in your note 4, I have the impression that this often happens after a few years.
Edit: Oh! And did you have to dowgrade you bootloader before install kitkat ? I also tried to install kitkat on a defective note 4 motherboard and I had a lot of bug, but it was without repartion and with a one file firmware (I did'nt find any 4 files/repair firmware for the n915fy with android 4.4). Also an important part of link of firmware listed on samsung-update for kitkat are dead.
