[L5] How do I completely unroot and reset to factory?

Hey, I'm pretty lost here.
I'm not much of a genius when it comes to android, but I tried to root my L5 anyway because I'm an idiot lol...Yes I did read countless websites and I did understand the risks involved etc whatever. Anyway, today I tried flashing cyanogenmod 10 on the L5 and pretty much ****ed up. Now I think i've lost root access, I can't uninstall superSU and pretty much my phone is ****ed up i guess. So the question is: how do I completely unroot and restore to factory settings?
I want to do this because I wanna give rooting and flashing a second chance. Is it completely necessary to restore to factory or is there a simpler way to just get it back to normal?
Thank you very much and sorry for the nooby/annoying question.
P.S. I did some searches on the forums and there's some similar questions but none that solve my issue so pls don't hate XD

To completely get it back to factory, try this..

[Q] Nandroid, Is it a solid backup option?

Hello there everyone, this is my very first thread and yes I did run a search but couldn't find ALL the information I was looking for.
I intend to use Nandroid as a complete restore-point so I could go back if I mess things up. And the phone would be like "What problems bro, shiet never happened to me". Lets say I want to try a custom ROM/Kernel/Anything but I am not sure whether it will work as I expect it to, it could brick my device. I don't know. My questions are:
1. If I make a complete Nandroid backup will it be able to bring my mobile back to life should things go wrong?
2. Will my Boot-loader stay unlocked? (I will make the backup after unlocking/flashing TWRP/rooting)
3. Will it preserve all essential things like ROM/Kernel/Custom Recovery (TWRP)/SuperSU/BusyBox? (I don't care about multimedia stuff)
Basically, is it a time-machine?
Replies are much appreciated, Thanks!

1. Yes, so long as it isn't a hardware fault
2. Yes
3. Yes as it is a complete snap-shot of the system in its entirety

Whoa, insanely fast reply!
Thanks mate, you cleared my doubts!

\o/
I also got some questions.
Is there any way to get a nandroid with my stock room, i mean, just do the nandroid backup without root, unlock bootloader etc... etc.. ?
Will I receive OTA updates from Google if I just unlock bootloader, root and change Kerne (trinity) l/ install Custom Recovery (TWRP)/SuperSU/BusyBox ?
I'm asking it because I have huge problems with my Sound (phones, speakers / they are to weak) and with my Vibration .... ugh, its weak too. Any hints about it ?
Thanks a lot!

You can't do a Nandroid Backup if you have the stock recovery. You need a custom one for that. And for a custom recovery, you need to unlock your bootloader.

[SOLVED] Flash to Stock with Broken Screen

Hi,
My Rooted Phone with Pure Nexus has a Problem (see Picture) .My Cat dropped it :/
I am returning it to Google, so i want to go back to stock, stock firmware, removing the yellow triangle and so on.
I barely see anything, and Touchscreen is not working, but i can go to the bootloader.
Recovery is not acessible without Touch.
Can you help me? I know how to flash stock firmware, but does this remove the triangle? I also disabled the encryption...
Hope you can help.

Hi... You don't have any datas to pull off of your phone first? Once you flash the factory image, your datas will be wiped...
In case you want to go back to stock and assuming your bootloader is unlocked, simply follow this guide:
https://forum.xda-developers.com/nexus-6p/general/guides-how-to-guides-beginners-t3206928/
To remove the open padlock at phone startup, relock the bootloader ONLY WHEN YOU'RE DONE FLASHING STOCK.
Good luck...

You don't need to access recovery if you only want to flash stock image. Personally I would do it with flash-all.bat command rather than do all the parts individually. Since you already know how to flash the stock firmware you just need to lock the bootloader after and you are good to go. Supposedly unlocking the bootloader doesn't void the warranty on the 6P but it couldn't hurt if you are sending the phone back to Google.

Thanks !
I was assuming the data is lost anyway, the good thing is i pictures are sent anyway automatically to dropbox, many things are in the cloud.
Okay, the bootloader thing was unclear, cool, thanks, ill flash it
Thanks!

G5 Plus Help unroot help!

Ok so I am just going to say I am a idiot and need some help. Please don't hate on me. I am not good with phone technology, but I followed directions to root my phone with TWRP & Magisk 12.0 and everything is working ok for the most part. The problem is I need a specific app to work for my job, but it fails to start due to the failed Safety Net. I would probably be able to figure out how to unroot it & relock the bootloader, but in my haste to root my phone, I did not backup the stock ROM image 1st. If anyone can help me figure out the next step to go back to a factory phone, I would forever be indebted to you. My specific model is an XT-1681 dual sim which I believe is from Brazil. I am in the US and not sure if I can use a different stock rom because I have tried searching to no avail. Please help if you can.
Thanks for your time.

There's a flash file for magisk which allows it to pass safety net. I saw it in the Lineage thread a few days back, but I don't know the exact origin.
Secondly, you can't relock the bootloader anyways. I don't know for sure if that in itself would cause safety net issues.

I appreciate the response, but I was able to finally locate the stock rom from a site linked on here & flashed and relocked the bootloader using ADB. Basically my phone is stock again & working like I need it to. I tried hiding the app in Magisk, but was unsuccessful. So I guess this post can be locked.

Check this thread, and follow local update method, then you need only of a command to lock the bootloader:
https://forum.xda-developers.com/oneplus-6t/how-to/how-to-update-return-to-stock-oneplus-6-t3870795

I just locked the bootloader for my OnePlus 6t. Follow the steps given below.
1. Backup all the important data. I am not responsible for any data loss!!!
2. Remove security lock screen (pin/pattern) or any thing
3. Download the stock rom from https://oxygenos.oneplus.net/OnePlus6TOxygen_34_OTA_020_all_1904032212_38e22c8b9abd42e3.zip
and transfer it to your phone.
4. Boot into twrp recovery.
5. flash the downloaded zip
6. Once done, reboot the system.
7. Now, boot back into the fastboot. (you can enable advance restart from developer mode for easy boot into fastboot)
8. Run fastboot oem lock
9. You will be presented with two options on phone screen. Select the one that says lock the bootloader.
10. It will wipe everything.
11. Once you in the system, enable developer mode and make sure that oem unlock is turned off. If not, turn it off and restart your phone.
And, you are done.
Let me know if it helps or if you have any question/concern.

MDM Tool in my opinion the easiest and quickest way to go back to 1000% stock. It will re-flash every partition on the phone so it's like brand new again. Using the MSM Tool guarantees that everything is back to stock and should restore the Widevine version back to L1 or whatever it was originally.

A question please
Once you lock again your phone, does it loose the root????
I mean, I have a Xperia 10 with the bootloader unlocked , it is root as well. Now root permissions for special aps work fine, but Google Pay is unusable, it does not work anymore. I hid root with xposed framework and rootCloak, but Google Pay still does not work now because the bootloader is unlocked...
As you should know, it is possible to lock the phone again... and many of those phones that relock their bootloaders keep the root permissions...
However , in my case, with Xperia devices (bq and xiaomi happen de same) is you lock the bootloader again, the phone resets, everything dissapear and root is eliminated. What is a really disaster.
As you have heard, the majority of phones, if you lock them again the root continues working, at least the apps that you gave them root permissions they continue working as they used to. But in my case this is different....ç
So please,
Is there any possibility to Lock my bootloader again without loosing the Root in my Xperia?????
Thousand of thanks!!!!

This is the only Thread where I could find some information about locking a bootloader again. Yes , this is dedicated to xiaomi 6t, but locking bootloaders is something common.
The only thing I want is to lock my Bootloader again without loosing Root permisions. Xperia devices seem to RESET everything when you lock the booloader automatically...., but perhaps there is another way.... a possibility to lock the bootloader without the phone is reset (loosing root permissions) ....
I asked for some help here. I regret any inconvenience that could may be caused on this thread with my message.

Nobody have your phone here how could we help you? Each phone has its specific behavior
If you relock a OnePlus phone you reset everything, like when you unlock it and it's logical. A locked bootloader is meant to ensure safety of data, safety that can't be provided with root access. Locked BL and root are antinomic.

Thank you for your message and understanding. So in Oneplus devices happen the same. So once you unlock the bootloader you loose Google Pay forever because it does not work wit BL unlocked...
Some users suggested me to lock again the bootloader,
Imagine:
- I become Root. Then I modify some apps
- I give to some apps root permissions.
- I lock the bootloader again.
- I won't be able to modify my phone anymore, but all those apps that were given root permissions, Will they be kept in the phone although it has BL locked again.
would it be like this?
or all changes you did while being root would dissapear with everything?????
If So... there is no exit what I see..., We have to choose between being Root users.... or being stock with Google Pay. It is a Pity.
I was not sure if all Phones reset and erase everything when you lock the bootloader .... but as I can see here, this is the reality. Root users loose Google PAY definitely.
Is there any option to solve this??
thanks again for your attention.
regards

Does google pay work??? What did you do in magisk exactly to achieve that???
I rooted my xperia using Magisk..., is there any tutorial or info that you suggest to me to follow ? or what should I do in magisk options???
I have 10 days with my phone stopped, trying and trying to make Google Pay works....Maybe this is happening to me because my Xperia uses Android 9.0.... or Magisk should make google pay work even being in android 9.0?
First Google pay recognized Root, and the app stopped working. I hid it using xposed and RootCloak
Then, Google pay recognized Bootloader. But now... I dont know what to do to hid bootloader unlocked for Google..., Google pay recognises it is unlocked... a disaster and a nightmare for me, I dont know what to do...
Thousand of thanks, I really thankfull for your help.
