{GUIDE} - fix for being stuck at samsung boot screen due to rollback protection - Samsung Galaxy Note 10+ Guides, News, & Discussion

Hi all I have been tinkering away and destrying my setup left right and centre to sort this process out but if you're unable to run the latest TWRP for your note from Ian and get stuck at SAMSUNG screen on boot then this process will fix that if followed correctly. This is due to the device's roll back protection.
This process will reset everything back to current date and get everything working on the new Oneui 2.1 base
Process for getting round SAMSUNG screen issue - please read through first and get the files you need before starting. I did this on my N976B but in theory it should work for other 10-range devices, notes indeed!
UNLESS YOUR RUNNING CRUEL KERNEL OR A SPIN OFF, YOU'LL NEED VOL UP AND POWER TO ACTIVATE MAGISK ON EACH BOOT
Needed:
Stock firnware
Magisk app
Twrp image
Pc and odin also patience and a brain lol
-Return to stock by flashing AP/BL/CP&CSC in odin
-Reboot and confirm oem unlocking greyed out, install magisk app and patch twrp image from Ian, also patch your ap file.
-reboot to download, meanwhile get the magisk_patched.tar and insert TWRP renamed as recovery.img in place of the stock patched recovery (keep this one for later)
-In download mode and with auto reboot off in odin, flash BL, Magisk_patched.tar(with the TWRP from Ian in), CP & HOMECSC.
-When flashing is complete exit download mode and immediately hold power and vol up and hold until on TWRP slider screen. swipe to allow modifications, format internal storage and flash multidisabler.
-Reboot TWRP and backup your current patched stock rom. FLASH THE STOCK PATCHED RECOVERY YOU SAVED EARLIER AND THEN FLASH MULTIDISABLER (THIS IS IMPORTANT AS YOU WILL THEN BE ABLE TO INSTALL TWRP VIA THE APP WITHOUT HAVING TO REFORMAT INTERNAL)
-Reboot straight to stock recovery (reboot from TWRP and hold Vol up and power until in stock recovery) and factory reset then reboot.
-You should now boot up as normal, setup your device, in particular have TWRP app and Magisk set up and running.
-Flash the Unpatched TWRP for your device in the TWRP app - reboot TWRP and check the box to kill that annoying swipe to allow modifications and then you are good to flash whatever rom or kernel you want for your device!

Excellent, thanks for testing!!!!!!!

@askmydas
you may find this useful - follow this to get your sec date reset then follow the process spelt out in the thread of the rom you want to use as you may need a different TWRP depending on what sec date the chef of your chosen rom uses.

Hey, when I get to " FLASH THE STOCK PATCHED RECOVERY YOU SAVED EARLIER" I try to do this and it tells me I don't have enough space. Any ideas?

I worked it out, I was trying to install "recovery.img" to boot partition, "recovery.img" needs to be installed to RECOVERY partition. Silly me. Fixed it now, but have a new issue:
After I flash unpatched twrp image through the app, now my phone will only boot into TWRP. I don't even boot with recovery button presses, but it will still boot into TWRP only. Any ideas?

I know this is an old thread, but it may be that my solution could help someone who is locked on the outside of the device (softbrick)
TD,DR: If you have softbrick and you can't boot the device at all, try flashing via Odin the BL, CP, CSC from a stock rom and the AP of another completely different stock rom.
I had an IMEI 0000 issue on my Galaxy Note 8 (SM-N950F), using Hades Rom (custom), and I needed to install the stock rom. As I was on the F(15) binary, there were only two roms (SamMobile and Stockrom.net) available for my country (Brazil) with this binary:
N950FXXUFDUD6_N950FOXMFDUD6_ZTO
stockrom.net_N950FXXUFDUG5_N950FOXMFDUG4_ZTO
And a via Frija:
SM-N950F_1_20210717024140_0wmgsx8iwf_fac
And no Combination Rom for that binary
After flashing these roms several times, I was always stuck on the “Powered by Google” screen, even doing cache wipe and factory reset through stock recovery several times. So I flashed the N950FOXMFDUD6, flashed the CF-Auto-Root and was able to boot the device. Once inside I noticed that it didn't solve the problem of IMEI 0000. I tried a few more procedures, ended up restarting to install TWRP, and the OEM is closed!!! (OEM OFF, Prenormal). I start getting the message “only official binaries are allowed to be flashed(recovery)”. I flash the stock rom, but it gets stuck on “Powered by Google” again. I tryed to install CF-Auto-Root and I get the message “only official binaries…” I can't log into the device anymore. So after four days of desperation, trying every technique possible, trying to create the Combination Rom by unzipping the AP file from the stock Rom and modifying the files inside, without success, I finally try a procedure I haven't seen anywhere else: I go to the modified Odin: Odin3_v3.14.1_3B_PatcheD, I selected the BL, CP, CSC files from the N950FOXMFDUD6 rom and the AP file from the rom SM-N950F_1_20210717024140_0wmgsx8iwf_fac
And it worked! I can boot the device

Cant Flash ROM using TWRP

Hey guys.
Little review of what happen:
Woke up today and my phone wasn't able to use any of my apps. So, I though no problem let me flash my rom. ( I use SlimKAT)
When I downloaded latest stable ROM I was ready to flash. I come across error while flashing "Executing update binary in <zip name>".
Things I tried:
Wiping:
davlik cache
cahe
system
Rebooting and flashing again. gave me same error.
Any suggestions?
UPDATE:
Now I cant even enter TWRP.
I don't know what went wrong, but at this point there is really no downside to just starting over. You could use odin to return your phone to stock then install TWRP or CWM then flash supersu then flash your rom again.

Honestly im not sure what I am doing at this point.
My ODIN MODE setting are followed:
Product Name: SGH T999
Custom Binary Download: Yes(4 count)
Current Binary : Custom
System Status: Custom
Qualcol Secure boot: Enabled
Warranty Bit: 1
Boot-loader RP SWREV:1
Im not sure how can i flash my stock rom.
Can you suggest where to start.
Thank you.
I'm no expert so do your own research - I think you can skip a step and get the route 66 version of your ROM from this thread: http://forum.xda-developers.com/showthread.php?t=1949687
IT should be the NC2 rom. follow the instructions there to use odin and install the route 66 rom onto your phone - you should then have a rooted stock phone. Then you can install cwm or twrp and flash your rom

My problem is that i cant boot in TWRP mode at all. It wont let me enter there.
When i try to flash via ODIN it wont pass.
Any other suggestions?
I got a feeling it have something to do with Custom Binary.
UPDATE:
I was able to get TWRP to boot from ODIN and it passes.
When I try to enter my TWRP it wont let me enter it will skip and go to loading screen of my rom and that's when it get stuck.
To use ODIN, you don't boot into TWRP. You put your phone into Download mode (hold the DOWN volume along with home and hit the power button - when the screen comes up hit the UP volume). You need to be running odin on your PC.

Boot Loop - Please help!

Tmobile Galaxy S4 (SGH-M919) Non-rooted
Problem:
The phone was working and then suddenly went into boot loop. The Samsung screen displays and right before it would goto the animation screen, it loops. I can get to download mode and the recovery OS.
What I've tried:
- First thought it was power button, sent it away to replace button but tech says it's not power button. The phone doesn't turn itself on when the battery is inserted. I can use the power button to turn on/off the phone fine.
- Cache wipe
- Factory reset
- Kies update/recovery
- Burn different firmware version (NB4, NH7, NK2, OH3)
- Tried just to burn NB4 twice consecutively without reboot (first time OK. when burn second time w/o reboot, the phone would display error saying the percentage completed is incorrect since it just finished 100%. Odin continues to burn to finish fine.)
Nothing seems to work. It still loops.
I am desperate. Please help! Thanks in advance.
Beocop
An update:
I tried CF Root and was able to get past he first Samsung screen, past the white TMobile screen, but it went back to boot loop again. Don't know what else to do. Any suggestions?
By burn do you mean you odin'd official stock rom? You cannot downgrade after 4.2.2 MDL so if you flashed OH3 then NB4 will not work anymore...just flash oh3 and root it. For root you can either flash recovery through odin then fash supersuBETA via recovery. Or (if you dont have a computer near you) use kingroot then push recovery through terminal emulator, then run remove kingroot app (google it) then flash supersu through recovery.

I've tried flashing OH3 (twice) also. It still boot loops. Then I tried CF Root to see if it does anything. It flashes fine with no problem. It still boot loops.
I can get into download mode and recovery without problem. It just won't let me past the boot loop.
Try different versions of odin/usb cables and reflash. Or and this voids WARRANTY. Put TRWP on your phone and try a different kernel or OS.

update:
- I've tried different odin versions (3.07,3.09,3.10). I've tried different USB cables. There was no indication on any error during the flashing process.
- I can flash any stock ROM after NB4 (anything before NB4 => Odin fail). After flashing stock ROMS, it can never get past the Galaxy S4 screen. It just boot loop.
**** I tried to download the OH3 stock rom from Sammobile but I always get a corrupt file error in Winrar. Can someone verify if the OH3 ROM on Sammobile is error free?
- I've tried TWRP (2.6.0.0, 2.6.3.1, 2.8.4.0). I've used it to flash CM-12.1 and Darthstalker_S4_V3 ROMs.
- After flashing all the custom CM ROM, it got stuck with the pink screen.
- I get nothing from Darthstalker ROM, just blank.
I am so frustrated with this process. It seems that I am doing something wrong in my process to flash the ROMs. I am missing something.
Can you please list ALL the steps necessary to properly flash a ROM? Please list every single step that you would personally take, no matter how insignificant (remove battery, clear cache, settings, etc.). Just treat me like a 1st grader.
Thanks so much.
Another update...
- So far, I've tried to flash stock ROMS (NB4-OH3) with odin. None of the stock ROMs will boot fully. All stuck at Samsung logo and bootloops from there.
- The best, but not fully functional, solution I've found so far is from:
1- Flash stock rom NH7 (tried NB4,NH7 so far) with odin
2- Flash CF auto root (CF-Auto-Root-jfltetmo-jfltetmo-sghm919.tar.md5) with odin
3- Flash CWM for recovery
4- boot into recovery, from CWM, install cm-11-20140110-SNAPSHOT-InstallerXNPQ02R-jfltetmo-signed.zip from sdcard1
5- From CWM, install gapps kk for 4.4.3 from sdcard1
6- Clear dalvik, format data + cache
It'll boot up fine. However, I get no sound (not from speaker or headphone). Google keyboard keeping turn on and off. The camera doesn't work. Video's cannot be played.
info "about phone":
Model: SGH-M919
Android version: 4.4.2
Baseband version: M9191UVUFNH7 (prob from CF auto root ?)
Kernel version: 3.4.0 cyanogenmod
Cyanogenmod version: 11.0-installer-XNPQ02R
Build date: 1/9/14
Build number: cm_jftetmo-userdebug4.4.2 KOT49H-installerXNPQ02R release-keys
Don't know what to do now. I've no idea why it won't take stock ROMs. I don't know why I am having problems in cyanogenmod. I freakin hate working on these phones.
Any ideas? suggestions? PLEASE!

Update:
-OK. I tried using philz cwm and burned this ROM but went through the installation process and picking choices. However, it wouldn't even boot.
-I decided to open up the phone to verify I had a SGH-M919. The sticker underneath the battery indicated SGH-M919. The phone has been using and updating OTA with T-Mobile firmware, the latest being OH3 with stagefright fix.
-After I removed the motherboard, what I saw underneath was disturbing. There was one big stamping showing "I337", which is AT&T. Many other stampings on the chips also show I337.
-In download mode, the product name indicated "SGH-M919".
So the question is, do I have a I337 or M919 phone? Currently, I cannot flash or install any firmware that is not for M919. I tried flashing ATT stock rom (I337ATTFNB1) with odin but it failed, indicating many errors such as PIT. I tried installing CM 11 for ATT but it also failed indicating that I need jfltetmo (M919) version. Ever since the bootloop problem, I cannot get the phone to boot with stock M919 roms.

[GUIDE] Reflash LEX727 With Stock ROM After LEX720 Update

I flashed the latest 20s Chinese ROM to unlock my bootloader and had trouble getting back to LEX727 19s ROM with a working SIM card, this what I did to fix it.
Goal: Get LEX727 back to 727 ROM from any Chineese Variant (LEX720) with a working sim card.
Logic: We need to get the phone back to as stock as possible so that we can flash dr4stic's ROM That will update from CN5.8.018s to US5.8.019s. First we need to install CN5.8.018s, but we need to do it from stock recovery, to get stock recovery back we use a TWRP backup made by suhridkhan, then copy the CN5.8.018s zip, rename it to update.zip and allow the phone to do it's thing It will take quite awhile to flash the stock CN5.8.018s ROM, but when its done we can then install dr4stic's ROM, but first we need custom recovery again, since we flashed stock recovery when we used the TWRP backup. So we reflash custom recovery (I recommend GrossoShop's TWRP as that is what worked for me, however others may work). Reboot into fastboot, fastboot flash recovery the GrossoShop TWRP, then we go back to recovery. Now we can install the upgrade ROM. Once the upgrade ROM is installed, we can reboot and we'll have a completely stock version of the LEX727 ROM with Stock Recovery. (oobe state)
STEP 1 INSTALL WORKING ROM
1. You will need a working ROM to copy the TWRP unzipped files to the phone (figure this out on your own, but you should already have something that works)
STEP 2 STOCK RECOVERY
1. Restore this TWRP backup
1. Send the unzipped files to your phone in TWRP/BACKUP/<Device_ID>/TWRP. (You need a working ROM to do this with USB, you can try adb pushing the .zip and adb shell unzipping but I had permisison errors. and found it easier to just move the files unzipped)
2. Reboot into recovery, Advanced Wipe everything except Internal Storage (where your backup is)
3. Restore from the TWRP backup, before restarting, do a factory reset wipe and dalivik.
4. Reboot, and you SHOULD be in the LEX727 Rom, however your sim card will not be recognized depending on the modem firmware you came from.
STEP 3 GETTING DOWN TO CN5.8.018s
1. Since we have stock recovery, we can now use it to flash down to the right Chineese ROM version for dr4astic's ROM update to work.
2. Setup the phone, and copy LE_ZL1_LEX720_CN_5.8.018S.zip, then rename it to update.zip
3. Install the update through the phone settings or browser. (It will take quite a while 15ish minutes)
4. The phone may reboot into an endless boot loop where it just keeps redoing the same startup flash, To get past this reboot into recovery and perform a "Clear data" wipe.
5. You should now be in the stock version of LEX 720 5.8.018s
STEP 4 USING THE UPDATE ROM
1. We need to flash a custom recovery again (I recommend GrossoShop's as that is what worked for me, however others may work)
2. Reboot into fastboot and flash your recovery software
3. Wipe everything, data included and reboot back into recovery.
4. adb push the update ROM and install it, wipe dalvik and do a factory reset wipe before restarting.
5. When you tap restart system from TWRP the phone will vibrate for about 7ish seconds, dont do anything, just let it do its thing. It will reboot and go to a black screen, then finish rebooting.
(this is perhaps the most risky step as we are returning to a stock ROM with stock recovery and might loose our unlocked bootloader)
6. You should get everything back to stock ROM with working SIM card and an unlocked bootloader.
note: I will be saving local copies of all the files required indefinitely, so if any of the above links break, I will re-upload.

Updating to Android O / Nandroid Restore back to Android N?

Used the search, used google, couldn't find any concrete answers
I am on Android N - unlocked bootloader - rooted via magisk, One Plus 3.
Could I do the following?
use TWRP to make a Nandroid Backup (System+Data+Boot) of my current set-up
then, manually flash (using twrp) Android O
find out I don't particularly like it
Go back to TWRP and Nandroid Restore back to Android N, as if no update ever happened
Or will there be issues?
Thanks
I do that with freedomos. 2.17(N)>3.1(O)>2.17. I restore nandroid and reflash rom

There won't be any issue. You are alright with the procedure. Just make sure you use the correct twrp recovery for oreo coz if you use the non compatible recovery then you won't be able to boot into recovery once the oreo is flashed and you are forced to go with the stock recovery
Process I followed when I tried oreo last week
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Do factory reset(wipe everything except internal storage) then flash oreo twrp image. Perform reboot. (no OS warning on reboot option screen will appear) just ignore it. It will boot to recovery even without the OS.
Once booted back to new recovery(oreo twrp)
Flash oreo stock zip and again flash oreo twrp image and reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu. Reboot to OS
Enjoy oreo
To go back to nougat
Reboot to recovery.
Perform factory reset as mentioned above.
Restore everything except bootloader, cache and dalvik cache
Flash nougat twrp recovery. Reboot to system.
Happy flashing.
Edit : use blu sparks recovery for nougat backup.

Hi, OP here. Thanks for this guide.
Unfortunately, it did not work out for me.
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Done
Do factory reset(wipe everything except internal storage)
Wiped fine although I got an error of not being able to wipe 'USB-OTG' or whatever it's called. I ignored it and moved on.
then flash oreo twrp image.
I googled oreo twrp image and got an img file with filename "TWRP-Oreo-OnePlus-3-3T". When I installed the img, it asked the options to choose Boot, System, or Recovery - so I chose System.
Then I rebooted and went back to recovery.
Flash oreo stock zip
flash oreo twrp image
Done
reboot to recovery(this time the device will get stuck with a black screen and white LED). Don't panic, just force reboot the device and go to recovery again to flash magisk/supersu.
This is where it ends. I get stuck at the OnePlus loading screen and forced reboot into twrp and flashed magisk. Once I boot up the OS, I get stuck at the OnePlus logo and that's it.
I actually re-did ALL of the steps again (in case I made a mistake) and still, the same issue. No progression.
Once I gave up on Oreo, I decided to go restore my nandroid
Reboot to recovery. Perform factory reset as mentioned above.
Wiped
Restore everything except bootloader, cache and dalvik cache
Here's the issue:
I press Restore (I uncheck both bootloader and cache, but there's no option for a specific dalvik cache- unless I'm not looking hard enough?) and I get the 255 Error.
Flash nougat twrp recovery. Reboot to system.
I tried to ignore that error and flash the twrp recovery.
Rebooted and it took me to fastboot. Regardless of I keep trying to reboot system it won't work.
I actually made two separate nandroid backups (the same 'everything except system image' as you've described) in case one of the backups was corrupted. Both backups ended up with the same error.
I got too tired of all these errors and just found a stock recovery and ROM and flashed it back. Now, all my apps and settings are gone. To be honest, I just want my phone back to where it was with Nougat.
Can anyone assist me?
@maxs8007, Like I said I did that already but nope still same issue. It wouldn't let me do matter what I did.

Hi, OP here. Thanks for this guide.
Unfortunately, it did not work out for me.
Take nandroid of all options available except system image. (system, data, bootloader, firmware, efs, etc.) on nougat twrp.
Done
Do factory reset(wipe everything except internal storage)

Buddy from my experience the whole thing too finicky and am thinking just factory reset and stick with stock rom. I wasted so much time already. Everytime I get different error, probably recoveries still not fully compatible with Oreo.

Could you please tell me what error you get on the lock screen? Could you post an image so that I can get a better idea of what's happening with your device? Also could you please confirm which files have you deleted? This time you need to delete 5 files which are related to lock screen setting and those are the only files responsible for lock settings on the device. I'm somewhat confused because I never ran into such issue while I did the oreo thing
If you have decided to flash stock then just make a backup of data partition so that you won't loose your data and you can easily restore it via twrp.

I read the entire post and here what I've to say. The above quoted steps is where you went wrong. The recovery needs to to be flashed as a recovery and not as system.
In your case the nougat recovery was never replaced with the oreo recovery because you flashed it as a system. This is where it went wrong. Sorry for the dalvik cache and USB - otg, I didn't mentioned about them. Those are the least important points in flashing though I should have mentioned that already
The next thing you mentioned is you went back to recovery which at that moment was nougat recovery and not oreo recovery. I'll link the modded recovery I used for oreo below
The next thing you did is you flashed oreo zip and again flashed the oreo recovery but as you flashed the recovery as system, the oreo stock rom was automatically replaced with recovery because you flashed it as system and the device didn't boot because there was no android OS to boot up
You got stuck on oneplus boot up screen. (this was going to happen because of the same flashing error at your end).
You were unable to boot back to nougat as well because of the same issue.. Never flash the recovery as system. This won't let you boot the device.
To restore your nandroid backup just follow the steps below
As you confirmed you booted to stock rom with a stock recovery.
Flash nougat twrp via fastboot
Boot back to the twrp recovery and restore the nandroid backup and you are good to go

I'll make a video in my free time to help you guys with the steps that I've followed to flash oreo rom and how i came back to nougat successfully.
Hello @maxs8007
Sorry I didn't have any screen shots of the prompt and finally I was fed up with the whole process and had to switch back to oreo stock rom.
Login prompt I was referring to was standard pin required load android. Black background with only pin entry.
BTW I tried blu twrp recovery oreo version and nougat version.
What's interesting is, after several failed attempts it said I got 10 more tries before phone wiped out but after 10 attempts it started counting backwards from zero, - 1,-2 etc., finally I had to flash stock recovery via fastboot and selected forgot password option which reset my phone.
BTW I have deleted all those files from data/system I found another thread but no dice.
Thank you for trying to help us all.
@maxs8007 followed your steps. Booted to oreo, didn't felt as stable as nougat then booted back to nougat. You saved me. Thanks.

I'm sorry that I was unable to help you. The thing is I never used the pin prompt to load android because I reboot too often to flash things via recovery and its too much of a hassle to enter the pin everytime the device is booted and I think it's too much to a security for a android device when there's already a lock screen present once booted to secure the device.
Please don't put the pin entry to load android next time if you flash stuff regularly. It will save you the hassle of going back to stock rom and recovery when something like this ever happens again. The files which I told you to delete in the image I posted above remove the lock screen protection completely
The login pin at the boot to load android was implemented to avoid unauthorized access to the device in case it gets stolen or lost.

Frankly no clue why deleting those files didn't reset my pins and I even deleted gatekeeper files too.
Maybe these are lock screen key files and android boot prompt stored somewhere else. Not sure though.

Not quite bricked my Honor View 10

Shortly after receiving my bootloader unlock code, I made a real mess. First, I tried to install TWRP via these instructions: https://twrp.me/huawei/huaweihonorview10.html
Specifically, I used the ADB/Fastboot method. Unfortunately, when I went to reboot to recovery by holding power+vol-up, it always took me to the Huawei eRecovery, not TWRP. I assumed the install failed after multiple attempts, and thought I would try to root with Magisk so I could use the TWRP app to flash the recovery instead.
I downloaded the ramdisk.img from here: https://drive.google.com/drive/folders/1kfNAjIwiMj8wpeDuJayiH2t-srYBBvN3
I found this link here: https://forum.xda-developers.com/honor-view-10/how-to/honor-source-program-t3732573
I then proceeded to patch it with Magisk and flashed the patched .img file. After doing this, the phone would bootloop a few times before ending up at the eRecovery again. I cannot get the eRecovery to get the packaged data for the Upgrade/Install recovery option, but when I choose the Factory Reset option, it reboots to TWRP (weird!) for about 3 seconds and then reboots to bootloader. I tried reflashing the original ramdisk.img when in the bootloader, but this made no noticeable difference.
My next guess is to try flashing recovery_ramdisk.img to try to remove TWRP and restore whatever stock image that was. I want some advice from the community first because I fear this may make things worse!
I saw that Magisk did in fact cause bootloops due to a compiler bug, according to this post: https://www.xda-developers.com/magisk-16-bootloop-crash-fix-huawei-honor-support/
Has anyone run into a similar issue? I assume since I can still get to the bootloader I can fix it, but I'm at a loss as to what the best next step is.
I flashed that recovery_ramdisk image. The result is that instead of booting to TWRP for a few seconds, it reboots into another eRecovery which allows me to do a factory reset and wipe the cache. After doing these, I still can't access the system.
So it turns out my device is BLK-104 and the problem was that I tried to flash files for BLK-109!
I'm surprised things worked as well as they did!
