when i unlocked my xt1550, i made a twrp backup of unmodified stock rom. and today i restored it. i got 59mb update but it always fails (yes, i restored stock recovery.) any idea what should i do other than reflashing stock firmware?
You need to flash the latest stock firmware available for your device. That's the only solution in your case.
Also, how can I tell what were the previous versions of Android that my phone had (STOCK)?
For example: there were several 5.1.1 versions or 5.0. versions - how do I know which one do I need?
Thanks.
The easiest way to have a routed rom would be to flash a stock rom from Google, flash twrp, and flash supersu from twrp.

Sorry if I didn't explain myself - my phone is rooted and I have a custom ROM. What I want to do is to go back to stock ROM but keep it rooted.
Thanks.
Flash a stock rom, then just root the stock rom. There is no other way unless you flash a stock pre-rooted rom.

So you can't keep it rooted while flashing stock?
And how do you know which versions are for your phone (if I don't want to go back to the latest Marshmallow for example)?
You can only keep root when flashing stock if you find a prerooted stock image.
Google search for nexus factory images.

Yes, I know that I need to Google for factory image, but there are several images with the same release. For example, there are three 5.1.1. (LMY48B, LMY48I and LMY48M). Same with 6.0.0. and 4 X 6.0.1 version. How do you know which one is for my device?
Thanks.
Any stock image for hammerhead will work on a hammerhead device. The reason it will delete root is you will have to flash system, and unless the system image you flash is prerooted, no more root.

Just trying to understand that difference between the different versions, or are these simply system updates, from XXX29K to XXX29S for example?
Changes in the android version 5.0->5.1->6.0 are fairly large system updates. Within 5.1.1 they are security patches.
If you have a rooted phone and talk about flashing, you should know this. Else you are a menace to your phone...
Root is a system modification - if you delete or reinstall the System partition, you'll lose root. But re-root is easy.
I recommend to read tutorials and get some knowledge before trying to root, flash or before asking those questions, where Senior xda-members just shake their heads.
The simple way to do what you seem to want is to back up all your important stuff (photos, etc.), install MMB29V (the latest March 1st 6.0.1 security version), install TWRP 3.0.0.0, and from TWRP flash SuperSU v2.70. It will take slightly longer than it's taken me to type this, but not much...
After that, when a new monthly security version comes out, flash system.img, boot.img & radio.img, and repeat the TWRP & SuperSU steps. No data loss.
Hi Folks,
Saw many users struggling to restore their phone after messing up with their phone either during flashing any custom ROM, custom recovery or even flashing stock update via Firmware finder or flashing any unapproved stock firmware via DLOAD method and event after trying various methods of reviving the phone unable to do so and they can not flash the custom ROMs as well, sometime due to FRP locked etc or various unknown reasons.
Please share your TWRP backup for such users so that they will be bale to restore their phone and use it rather throwing it in frustration. It could be either TWRP backup for stock MM, Stock Nougat, Custom MM or custom Nougat
Please do not forget to mention the model number and the backup type as TWRP backup for stock MM, Stock Nougat, Custom MM or custom Nougat so that user download and restore only the backup they need rather messing it up again.
It can be system+boot or system+boot+vendor backup.
Example- BLN-AL10 Stock B375 Nougat
Thanks and happy flashing.
Hi all, I'm sorry if this is a stupid question but I just wanted to make sure I don't mess up my phone.
So I had flashed a Custom ROM (Resurrection Remix) on my Galaxy S7, but after a while I wanted to reflash it back to stock 8.0 Oreo which I have done successfully. Now of course the knox counter has been tripped, however the phone is unrooted and also no longer has TWRP as its recovery (just the standard android recovery now).
Now that I have flashed it back to stock, would it be safe to perform OTA updates on the phone? Someone had told me it would not be possible as I had flashed a custom ROM before and I just wanted to get some other opinions.
Thanks in advance!
OTA updates gonna work fine
Hi everybody, I have a SM-G920F with android 7.0 rooted with magisk and TWRP, but with stock ROM.
I'm planning to give NexusOS 9.0 a try and do :
Backup my data and settings with TitaniumBackup
Backup everything in TWRP
Flash ROM,magisk,Gapps according to NexusOS's thread
If I want to go back to Stock, what do I have to do ? As of now, I would think of :
download my latest firmware on https://www.sammobile.com/firmwares/galaxy-s6/SM-G920F/
Flash it through Odin by selecting the firmware in "AP"
But do I need to do anything else before/after flashing stock ROM, like wiping something ?
