[Q] Getting back root on DE? - Verizon Galaxy Note 4 Q&A, Help & Troubleshooting

My Developer edition Note 4 starting boot looping. I used Odin to reinstall a stock recovery tar and ended up with N910vvru1anj5 baseband version with no root nor TWRP. I finally got odin to work to install twrp 2.8.5. However whenever I try to boot into recovery I get the Samsung recovery and not the TWRP recovery. The Samsung recovery shows to apply update when it comes up. Superuser does not work and I do not have root.
I have a twrp backup on my sd card and the Samsung recovery sees it but I assume that it will not install it properly.
Why is TWRP not working and how do I get back to root. Is there a problem with the rom I have installed?
When I go into download mode it still shows deveoper edition.
Thanks
I did install the 1st update for LP by mistake but was not able to install TWRP prior to the install nor did I have root.

Does it still show Mode: Developer in Download after you did the update? If it does it should still be a DE. Did you back up the aboot partition? Here is where you need to go to do it. If you have it backed up you can always get back the developer mode.
Maybe if you wipe data then reflash the stock recovery it might work. Go into Settings/ Backup and reset and do a Factory data reset. I've never worked in stock recovery but I think it's possible in there.
If you can get this back you need to do that aboot backup.

Go into stock recovery and factory restore then flash TWRP, you should be good

It still show developer mode. I did backup the aboot. My phone is working ok with current rom but I miss Titanium Backup with unrooted phone.
When there is a new Lollipop Rom for DE I will do a factory reset and see if I can get back to TWRP and root with Lollipop. I hate having to restore all my apps and settings after a factory reset.

[Q]briked S3 i747

I tried to factory format my phone through TWRP, then when I tried to restart again, it never comes back.
I still have access to TWRP, but when I install zip files I downloaded, it always failed. I tried to use Odin, it failed to flash an image in.
Plz help me.
Many thanks.

What format option did you select in TWRP and hope you didn't accidently remove your OS? The device could fail to boot if you don't have an OS installed. You may be able to flash a complete stock restore image via TWRP. Would you recall what Android version you were on before the brick? Also what is your phone model and carrier?

Mine was ATT S3 I747 with Android 4.3 system. I did wipe my OS during recovery. That caused the whole problem. Then I use TWRP to flash a system and a kernel in. I was unable to flash bootloader and modem in; I did not know what is the problem. The weird thing is that I successfully start my phone and used it for a while. When I rebooted it, it dies again. I tried to install the some boot update in this January. It never works again. Any advise?

You can try flashing a complete stock system to get your phone back to working condition. Since you already had 4.3, flashing zips often fails if there is a bootloader incompatibility. The stock restore should do it. Please go to the following thread ....
http://forum.xda-developers.com/showthread.php?t=2658486
Download the stock restore zip to your PC. Use another device or something to load it to a (micro) SD card. Insert the card into your phone. Boot into recovery mode and flash from TWRP. When done, wipe your cache/dalvik and reboot to system. Let's know if this works for you.

Recovery Fail!

So two days ago I thought about installing Vision X rom on my Note 3 (T Mobile).
I downloaded the ROM and then backed up my current ROM (nandroid). I had Phillz touch recovery then.
Then I thought about going to TWRP and thus I downloaded the latest zip for my phone and flashed it via Phillz upon trying to reboot into recovery it got stuck in the screen "Rebooting Recovery...".
When I restarted it would still try to reboot into recovery and get stuck. I got out of that by going into download mode and then selecting "Restart Phone".
After that I looked for solutions and upon failing to find any I thought about going back to stock and starting from ground zero. I managed to flash the latest stock using Odin however I forgot to do a factory reset before hand.
When I tried to do a factory reset in my, now stock, phone it failed and then got stuck trying to get into recovery. It would flash "Rebooting Recovery..." then restart and flash that in a loop.
I have lost my root as well in the process and trying to root using Odin and CF-Root just get's me back in the recovery boot loop. I can use the phone OK however this is not a stable situation.
I'm sure I've made some serious errors in the tinkering and would like to get my recovery back. I really love Custom Roms. Any kind and knowledgeable souls out there to help me in my cause?

Go to the Playstore and download TWRP Coordinator and then
use it to install the latest TWRP recovery for your phone.
Once you can get back into TWRP recovery you need to flash
the cf-autoroot for your phone. Be sure you flash the CORRECT
version of cf-autoroot for your phone's model.
Good luck!

The app is constantly crashing!
It would start for a second then close. I tried the TWRP manager as well with the same result.
I've lost root access when I Odined back to stock, won't I need root access to install new recoveries?
Sounds like you flashed the stock 4.4 firmware and now need recovery to root. Flash this TWRP file using Odin http://goo.im/devs/OpenRecovery/hltetmo/openrecovery-twrp-2.7.0.1-hltetmo-4.4.img.tar
Once you flash it, you need to boot into recovery to install supersu to root.
Switch off the Galaxy Note 3 (remove the battery and reinsert if needed)
Next, press and hold simultaneously Volume Up, Home and Power.Release the buttons when the screen flickers and wait for the TWRP menu.
Select Reboot, then System and install Supersu for root.
Once booted, open Supersu to update it and grant permission.
Hope this helps. Good luck.

T700 Soft Brick

Looks I've managed a soft brick. I've been able to get it back into recovery and I've been able to push stock recovery (and also just tried TRWP). Odin seems to work and the T700 appears to accept the recovery. Following reboot I'm still getting stuck back to the Samsung boot animation but then I'm stuck at the boot screen; nothing past that.
I'm not sure if this should help any, but while in recovery mode the upper corner reads the following:
ODIN MODE
PRODUCT NAME: SM-T700
CURRENT BINARY: Custom (after flashing TRWP, when flashed with stock it said 'Samsung Official')
SYSTEM STATUS: Custom
I would appreciate any assistance and thanks in advance! This is my first soft brick since Eclair!
Have you tried flashing stock firmware with odin? Or restoring your twrp backup?
Firmware, yes. I flashed TRWP to see if I could restore a backup, but after the initial reboot after the TRWP flash the device still returns to the Samsung logo.
Try download mode then restore to stock using Odin and then go into stock recovery and reset then wipe cache and reboot.
Sent from my SM-T800
I've tried that but perhaps I'm not following the proper set of instructions. Would you point me in the proper direction? I won't be offended by 3 year old instruction sets.
(This is stock recovery)
Reboot your tablet into Recovery Mode
Next, take the following steps using the Recovery Options:
– Wipe data/factory reset
– Wipe cache partition
Back to main menu and reboot using the option reboot system now.
If that doesn't do it then I dunno. I know it helped me after messing around with flashing and whatnot.
I don't even bother doing it anymore. I just root stock and add/remove the stuff I don't want.

I decided to walk away from it for a day and some change. In the meantime that allowed for the battery to run out. It shouldn't have had a bearing on the fix, mostly because - well it just doesn't make sense - but after charging full following the drain it took a firmware flash to stock.
I appreciate the sanity check!

SM-P600 Stuck at Samsung boot screen

My tab was running stock 5.1.1 rooted and twrp
I flashed the cm-12.1-20160501-NIGHTLY-lt03wifi to check it out, and it was giving me issues so I booted it up in download mode and reflashed P600UEUCNI1_P600XARCNI1_HOME.tar.md5
and now its just sitting at the samsung loading screen .
I cant seem to get it into any type of recovery mode, only download mode.
anyone have any ideas on what i can try to do to get it booting again?
Ok correction i am able to boot into recovery mode.
Ok i was able to get into recovery mode finally..
I reflashed the cm12.1 zip and that is booting.. but still having issues ... it rebooted after doing the initial setup..
I would love to get back to a stock type rom...
You're gonna need to boot into recovery and wipe data & cache.

I was able to get it booting CM again, but i really would like to go back to the stock rom, but flashing it via odin doesnt seem to work, that when i get stuck at the sumsung screen..
now i was thinking this might be because twrp is still the recovery and not the stock. so i need to find the stock recovery to put back and try that i guess
If you're flashing stock firmware, it should replace TWRP with stock recovery.
You're also going to need to wipe data & cache almost any time you are switching ROMs (and definitely if you are switching between stock & CM).

Thats what i thought too about the recovery.img
so you think i should wipe data/cache in trwp then reboot it back to download mode and flash via odin?

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

So I'd restore the nandroid via twrp, and I should be good to go?

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.

Thanks for the advise.

Go to twrp - advanced - file manager - go to root folder - data - system - and delete files with .key extension. There will be 2 files delete both and reboot.

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.

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.

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.

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.
