Hi!
I would like to unroot my Nvidia Shield TV for performing an OTA update. SuperSU's full unroot method asks me to restore the stock boot image like seen here. Would this trigger a factory reset?
Kind regards
Kokosnuss
No, but there's always a risk of encountering issues when flashing stuff, so make sure to have a backup.
Thank you!
Unrooted successfully.

Reminder:
If you installed CWM and Rooted zip from recent updates,
DON't DO EVEN Factory Reset from "Privacy" Tab of the OS.
It is clear that you should not do that in recovery menu,
just a reminder that you should not even do it from Privacy tab within the system menu.
It will reboot, and brick your device.
I am at work, I will restore my DS7 later when I am at home.
I thought the privacy reset is just to wipe USER data. But apparently, it wipes more than that.
By the way,
Restore from CWM wont help in this case.
Re-install dj336.zip wont help in this case.
Wipe cache/wipe user data/ re-install dj336.zip wont help in this case.
Seems the only way is to flash original boot and recovery and then do everything over again.
I am a little disappointed that the restore in CWM did not help at all. besides using it to flash dj's rom, what the hell other benefit we are getting from this CWM anyway?
Nothing. Lol. Its bs but hey least there is a recovery there
sent from somewhere
hu... took me a good hour to recovery from an almost brick situation.
Thanks for all reference posts in this forum. =)
Hi friends,
I wanted to be very sure before I tried anything stupid and end up bricking my phone.. I hope you will find time to answer some of these questions..:fingers-crossed:
Is it safe to factory reset a rooted HTC One M7?
If it was safe, do I need to do anything special like factory reset it from TWRP (what?) or just hit the Back Up and Reset option in the Settings of the phone?
Will I lose my root access?
Appreciate your time! :victory:
Much respect,

Factory reset from backup reset will fail because you don't have stock recovery
Factory reset in TWRP deletes the /data partition
make a backup first just in case.
If you want a true wipe factory reset you need a RUU (ROM Update Utility)

I did an Odin install of MM for the 910T stock rom and unfortunately tried the encryption. I thought it would give me the option to decrypt, but that is not the case.
I was able to root after the encryption using the method here:
Root/Recovery (http://forum.xda-developers.com/not...overy-n910t-t3-marshmallow-pe3-guide-t3406870)
Xposed (http://forum.xda-developers.com/note-4-tmobile/general/pe3-xposed-n910t-t3-marshmallow-t3406950)
What I want to do is go back to an un-encrypted state.
What is safe to wipe using TWRP?
I know nothing aboit encryption but......First thing I would try is odin again and start over.

That is the intention, tried a reset but the encryption was still there and I used an Odin install yet nothing was changed or altered when I rebooted.
What I need to know is what can be safely wiped in the advanced wipe in TWRP.
Everything. Twrp might be able to decrypt. But u should be able to factory reset and then odin restore all.
Hello,
Could I brick my device if I run the wipe data/factory reset?
My device is root, thanks

Generally no. You will likely loose root.
I do not care about root (could I do it again), so it can be safer than flashing a recovery?

Can't boot or flash a custom recovery on this device. What are you attempting to fix/accomplish?
I finally flashed the device after that I did run the wipe date thing, cause kingroot wasnt working well...
Now I am root again.
I'm afraid to remove some application system again because I had to flash the rom twice for this reason... Althogh I think it is not so necessary if installing Nova Launcher, how I did, apps/pages systems are a bit llitle more hidden now.
I were searching to find a tutorial about than ones apps system could be removes and than ones not, but it isnt so important now for me.
I have Xperia Z3c 5.1.1 rooted with locked bootloader. It is on wifi only. Yesterday I've turned wifi on and suddenly have got device off. I tried to reboot. I see the Xperia logo and bluish Xperia start screen with waving elements. However, the home screen and apps are not appeared, have just black screen. The battery is fully charged (green led). I tried several times reboot today as well with the same result. I believe the phone is soft bricked.
The phone is rooted with NDR Utils and TeamWin Recovery (TWRP). I also have Titanium backup.
After reading this forum I found several ways to unbrick the phone:
1. Soft reset (Power + VolUP) up to 1 vibration.
2. Hard reset (Power + VolUP) up to 3 vibrations.
3.Use flashtool (flashmode) and flash ftf file. Should I flash Kernel as well?
4. Use phone System recovery (Power + VolDown).
Which method I should try first? Can I save root and my current Lollipop firmware or I should go and start from the scratch with rooting and flashing 5.1 again?
Thank you for your suggestions.
Try soft reset and hard reset. This don't break your phone but it is worth a try. If this will not work do NAND backup (full backup of phone) in recovery. Now you can try clear cache in TWRP (wipe -> advanced wipe -> check cache -> swipe to wipe). If this don't work try clear dalvik/art cache.
If this metods didn't work flash same rom (if rom was't pre-rooted root after flash). If system starts you can restore NAND backup without system partition and cache.
If system don't start after restore backup the last chance is clear rom flash.
I don't know where the problem is but in my place I would do that
Thank you krzysiek546 for your help.
I have tried soft and hard reset, both unsuccesful. I made backup and wiped cache and dalvik from within TWRP. The phone after apps optimization has started the system (there was black screen but I was able to see home and Back buttons, which were non-functional, i.e non-responsive.) The screen became black again after a few secs and did not return to the life then.
I think I'm going to flash the Rom. My question is there is any chance to get brick again in case I will restore from the TWRP backup (if there was a virus or something?). May be I should wipe data, cache and dalvik and only then made a backup?
Also, when you saying "a clear rom flash" as a last chance do you mean factory reset?
Thank you.
Don't wipe data before backup. This is like doing backup after format system. It doesn't make sense.
Have you tried this metod with flash with nand backup and flash same rom (zip from twrp or ftf from flashtool) and restoring data without system partition (it's important)? In this i mean something corrupted system files. In this metod you can save your data. You just reinstall system and restore data from nand backup.
When I sayed "a clear rom flash" i mean wiping all data in recovery and flash rom from flashtool or twrp without restoring anything. You can do it first. I think now it's beter because you can check did that fixed your problem and if this "clear rom flash" repair your problem you can restore data from backup.
As to your question. Yes you can get brick from restoring data from twrp but in my opinion this virus or something must have root permissions to do this.
After installing the newest supersu, I also get this bootloop. Is there a chance to undo this without wiping data?
Edit: ok, after hard reset, flashing SU, cleaning caches etc. (which all did not help) I reflashed the ROM, now it works again. Pheeew.

Try to install SuperSU v2.81 - author apologized for inconvenience caused regarding 2.80 update. I got this bootloop too and solved it by installing SuperSU v2.81.

When I had that error, it was still V2.80 and no update round the corner.
Thank you for the link. Worked great for me. Installed per TWRP.
Well, in my case I didn't updated SuperSU, just have turned on wifi. I think the problem may be in Wallpaper app I have installed previously. It changes wallpaper every day, but I noticed sometimes the background of my home screen where all apps are became black.
Anyway, only "clear rom flash" with wiping cache, dalvik and data helped me. I then installed pre-rooted Lollipop ROM I made before and restored all custom apps from the Titanium backup. BTW, don't try to restore system apps from the Titanium, I've got the error with Xperia keyboard and have to make a restore whole system from TWRP.
Thank you krzysiek546 very much for your help.

I also got bootloop after installing latest SuperSU from Google Play.
How can I install 2.81 (or 2.79) when phone is in bootloop?
