[Q] Stuck at water motorola logo after unroot

Hey guys, I tried to unroot my XT1097 pressing the button at the SuperSU app, but when I restarted the phone, the phone wouldnt boot, I'm stuck at the motorola "water-ish" motorola logo. My bootloader is unlocked with TWRP. What can I do to fix it?
Thanks in advance (and sorry if I couldn't find an answer doing searches )

i have experienced this problem many times when trying to restore the MotoX 2014 from either a nandroid backup, "fix permissions" and even a factory reset in TWRP (when i did not also wipe the user files). it is worth noting that I never had these problems until after the lollipop update. perhaps it is a consequence of whatever they did to allow the option to encrypt bootloader (which is a feature I have opted out of).
the fix is simple but a real PITA assuming you do not have all your files like pictures etc backed up. I will list 3 options below. the first option is an attempt to get it to boot without wiping your files. be aware your options are contingent on the type of recovery you are running (i.e. TWRP or stock). the nutshell answer: In order to restore full functionality you must wipe everything including user files. I do not know what recovery you have, but if runnning TWRP then the basic factory wipe is not enough when running lollipop.
1-in TWRP recovery, go to "wipe" then "advanced wipe," check the "system and click "repair or change file system" then click "repair"
2-in TWRP recovery, go to "wipe" then "advanced wipe," check "dalvik cache", "data", "internal storage" and "cache".....DO NOT CHECK "system"
3-IF the above steps fail or if you have stock recovery, just perform a factory reset. you should be good to go at that point

I had this issue with my Nexus 7 after unrooting to take an OTA to 5.0.2. Unfortunately the only way I was able to fix it was to use stock recovery and clear user data and cache.

[Q] 5.1 ZIP decrypt, no wipe

Is it possible that there will be no wipe update 5.1 ZIP with no encryption? Works like OTA.
I'd like to update from 5.0.1 (no force encryption) to 5.1 without loosing my data. The best for me is zip for TWRP

Well if backup everything in twrp to an external flash drive then it shouldn't be an issue. I know people have side loaded the OTA via ADB but it hasn't been working for everyone. You obviously can't take a normal OTA if you are rooted so you could try that. Alternatively I would download Parcel if you have root and backup all of your apps and data for each one that you don't want to lose then transfer it to an external drive so you don't lose it when flashing the updated images. From here you can install 5.1 and then simply restore all of your missing apps and data using Parcel. It works really well and much better than TiBu for restoring data in apps. I use both TiBu and Parcel for different things. The above is only if you can't find any alternative ways to get it loaded in TWRP

There's a stock based ROM in dev forum. Flash that followed immediately (without booting) a kernel with no force encryption such as elementalx and you'll be good.
Or just fastboot flash a system image followed by immediately boot into recovery, flash kernel and SuperSU

So what if we wanted to, coming from encrypted, decrypt without a wipe?

nope. your internal storage meeds to be reformatted. save on a computer anything you would need.

Best way to flash update.

So what's the best way to flash a update and not lose data? If it's just a security update and not an actual version difference, what's the best way to do this and not lose data? Keep in mind, my device is unencrypted. I was thinking flashing everything except userdata, and then booting into TWRP straight away and flashing a kernel before first boot, would this work?

This is how I do it:
Copy/download new zip with prerooted lite stock rom of Danvdh to internal storage.
Boot Twrp-recovery.
Wipe system partition and caches
Flash new rom (zip)
Twrp file manager - restore layers from back up.
Reboot

So it's easier to just use the zip rather than flash with fastboot?

Yes, and I only backup the data partition and recovery on the phone.
Till now I think the method is comfortable and faster for the monthly updates. Everything that's needed is on the phone.
When there is a complete new Android, like N,
it could be different. Especially when kernel, bootloader and radio are new. We need a modded kernel that does not forces encryption.

Stuck on TWRP after attempted restore

Hi guys.
So after developing an audio bug on Lineage OS 15.1 (a story for another day) I decided to restore one of my old backups via TWRP (unofficial decrypt-friendly version).
I press restore, get some sort of error about mounting /system and then on reboot I get a message asking me to factory reset which takes me to TWRP. Not too surprised by this point because the Huawei bootloader is quirky.
However, when I go into TWRP, it simply gets stuck on the loading screen endlessly. I left it for several hours and it didn't budge. Rebooted several times.
I tried reflashing TWRP via fastboot, no dice, same result. I flashed the official recovery too. That loads fine, but obviously I can't restore with that because it doesn't support encryption.
So I'm a bit stuck here. I've read somewhere that it takes ages to load when you have plenty in the data and cache folders, which I do, but I really don't want to wipe because I have a full week of precious holiday photos and videos I wasn't able to back up (No access to a PC at the time).
Any advice?

Not sure how to fix the TWRP restore problem, but have you tried connecting to your PC while in TWRP? If I remember correctly, it'll allow you to connect to a computer so you could access your storage and backup the files you need.

Problem is that everything is encrypted, so even if it does show up it will be gobbledygook (nonsense).

Lesson to learn from this: always backup before trying to update ROM or flash something new.
I guess what you can do is to try to flash Lineage again and see if you can make that boot.

Yeah, there's a few reasons that happened. Usually I autobackup everything but I had been away from wifi for a week. I backed stuff up via Titanium but obviously that got encrypted too. Restores also have never given me problems in the past so I didn't expect anything to go wrong (still not sure what did).
Anyway, I'm not sure how to flash lineage without TWRP, especially with everything encrypted. To have any chance of getting it to work I'm guessing I'd need to flash it the same way I did originally, which was with everything decrypted which makes the issue moot. Maybe I'm wrong though.

Try flashing a treble rom via fastboot. Then wipe data and cache.
fastboot flash system "GSI. img"
fastboot erase userdata
fastboot erase cache
fastboot reboot

Thanks, but I'm trying to prevent loss of data. I'd probably just use e-recovery if I don't mind losing data and want to reset to start again from scratch.

Erasing userdata and cache is just factory reset. It won't wipe your internal storage which where your photos are kept.

Ok, turns out once I chose the "download latest firmware and stock recovery" from erecovery it didn't wipe the internal sd data!
Everything is still there and I can access it now from the huawei stock ROM even though I came from lineage OS. It thankfully does not reset the encryption keys or the pattern lock, so you'll be just fine once you do a system boot and go through the regular setup process.
I recommend this approach because it's pretty hassle free.

Glad you found a way to keep your files, mate

Rooting Note 8 without wiping

I've read a couple of threads about this matter and it seems that I have to wipe the phone anyways because of installing TWRP?
I want to root only for one reason, to recover very important camera videos I accidentally deleted. And I only know one way to recover them and it requires rooting.
So If rooting requires full data wipe, will I still be able to recover my videos?
maybe If I backed up everything on the phone this will increase the chance, or once I do the full data wipe there will be no way to get the videos back.
Thanks.

I think you have misunderstood a few things.
TWRP is a custom recovery. When you flash TWRP, you change the layout of a small dedicated "room" in your device, which has nothing to do with your data, which sits in a different room.
You wont be able to flash TWRP without having OEM Unlock available.
The moment you have it available, and you flash TWRP, you need to boot directly to TWRP after the flash, meaning, the system cannot start as it will sense the change, and flash a package here that deletes a few files that will take the phones ability to sense the changes.
After that, you flash the Magisk package, which gives you root, and preferably, wipe "cache rooms", which none of this affect your data and pictures you want to save.

are you sure about that ?
i have note 8 and i'm thinking to root it using magsik and twrp , but i'm afraid it wipes my internal data?

Any guide I have seen indicates that the mere unlocking of the bootloader requires a wipe.
