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.

recently wanted to update my rom (Resurrection Remix-N). When I boot into TWRP, I get an error 7. I was also having issue with titanium backup (keeps crashing) so I was thinking it was the ROM since I haven't updated in a while. Since I couldn't update with TWRP and error 7, I decided to switch ROM.
I did a nand backup, then proceeded to factory reset in TWRP, reboot recovery (habit of mine).
And now I was stuck with at TWRP decrypt Data because my previous pattern is not working. Gives me a "pattern failed, please try again!")
My question, is there a way to at least get my data off the device (backup to laptop and restore later)?
I can boot into fastboot. but I can't see device storage on laptop.

A method thats worked for me in the past is to use fastboot to re-install TWRP. Use TWRP 3.0.4-1 and reboot your phone to recovery.. You'll be im MTP mode so you can transfer files onto your phone for flashing.. If you get code7 in TWRP, use a different FIRMWARE+Modem version.. If you want the latest RR use 4.0.3.. Your data should be safe..

I had that once when i messed about with f2fs.. Only way i found was to flash stock ROM and recovery, reboot and fastboot TWRP again.. Now my laptop could see my phone and i could start from scratch again.. I'm sure there is a better way but this worked for me.. Sorry i cant be of more help
Flash all 670 img's till one works :laugh:
I think error 7 is related to firmware flash 4.0.3 and then your rom of choice should be fine

You were lucky. I flashed stock recovery so I can flash stock rom but still no luck. I miss samsung odin.
Thanks anyways for ur contribution.
Down graded to Oneplus 2 until I fix my phone.
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.

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 @maxs8007
thanks for the instructions. I did all that to get back to my nougat rom (PureFusion) and all seem good and phone booted fine. But i am stuck on login screen after booted up. I tried my correct password several times but to no avail. anyway reset my password without factory resetting again?
Thanks for the advise.

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.

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.
