[Q] Lost ROOT after manually updating last OTA via TWRP

As title says... I had unlocked bootloader and flashed TWRP then SuperSU and ROOT was working fine.
- Last OTA I got which was yesterday (as only just got the phone) was XNPH33R.
- I used TWRP to install the update which went fine except I lost ROOT access.
- Went back to TWRP and reinstalled SuperSU which shows as installed on my phone - however no apps that require ROOT can get ROOT access and RootChecker shows that the phone is not rooted.
- Rebooted to System / Tried to Fix Permissions / Tried to reinstall newest SuperSU - nothing works
Does anyone have any suggestions as to how I can regain ROOT or is not possible on XNPH33R?
Further issues I have now got no ADB access in Fastboot no matter what drivers I install... don't know if this is all linked!!!
Jesus christ
Any help appreciated.
Thanks in advance

Too much work if you do a full wipe and re rooted ?
Also try to put zip file with airdroid and flash it in download mode

So I've found out that although adb was telling me that it couldn't recognise any devices in fastboot mode - all the actual commands from the OnePlus One toolbox were actually getting through as I relocked my Bootloader to see what would happen and then tried to Flash Recovery and it told me Bootloader was locked - so that confirmed adb commands were working.
To solve my ROOT problem I did the following:
1) Flashed CM XNPH22R
2) Installed all OTA updates
3) Unlocked Bootloader
4) Installed TWRP - then chose REBOOT TO SYSTEM (this told me I wasn't rooted and then followed prompts)
5) I chose to install SuperSU from Play Store
6) Opened SuperSU and updated binaries
7) Turned off Update CM Recovery in Developer Options
8) Rebooted and installed and ran Root Checker....
9) Success!

Remove the respect CM root settings from the SU settings menu and your root will come back i had the same problem until i found this out.

[Q] Not able to root my Nexus 5

Device : Nexus 5
Premise: Not able to root using SuperSU
OS: 5.0 build: LRX21O
1. I flashed my Nexus 5 with the factory image of the above build.
2. Boot loader unlocked
3. Custom recovery installed(CWM)
4. Tried flashing SuperSU 2.16
-While rebooting, I got the error "Root privileges might be lost"
- Clicked fix
5. But, rooting didn't come through.
6. SuperSU says "There are no binaries and it can't install"
Any fixes? Please help. This is getting on my nerves.
PS : I don't wanna use CFAR coz it will erase everything even though the boot loader is unlocked. I don't want to lose any data.

Wow, this phone is a long time out waiting for this option to root, let alone TWRP. Alot of people off androidforums.com were putting in requests with kingroot and guess it paid off. Have you checked to see if firmware download is available for this phone? Besides a system pull off another device, these are the only options to fix any type of softbrick!

Will this root zte9518abb (ZTE Warp Elite)?

Zte N9515 Boost Mobile.
I rooted the zte n9515 warp sync from boost mobile about a year ago, I received an OTA update one day, unrooted the phone and the phone still is stuck in a bootloop. I am able to get to stock recovery, but, my issue is I have done everything I could think of to unbrick that phone. Zte updates don't work, stock firmware doesn't work, zte open gives me a partition mbn error, all kinds of flash tools using .pit files bin files IMG files.... I haven't found a way to fix it yet... I'm not too familiar with adb commands and I've done the research.. Using android SDK I only receive an adb rejected shell command error and adb sideload continuously gives me E:2 footer[2]=0x00 footer[3]=0x00 E:signature verification failed error message... No matter what I sideload. I need help fixing this issue if anyone has a suggestion or the answer to this I would really appreciate it....

please i need any rom for this phone

We can get temp root with previous versions of kingroot but the phone reboots a few minutes later and without root. we cant get into the bootloader through adb either it just does a normal restart... we dont have read/write access either and i've tried the adb command to grant it but i'm not sure it worked

[Completed] Help with reinstalling bootloader

Hi.
I am relatively experienced user who has rooted and installed custom roms on samsung galaxy and HTC desire phones before.
I have now attempted to root my alcatel onetouch pixi 4 (4034X) using instructions from this thread :- https://forum.xda-developers.com/android/general/alcatel-one-touch-pixi-4-t3376597
I got as far as flashing twrp recovery and now the phone is stuck in constant reboot. I downloaded alcatels mobile upgrade tool in hopes of reflashing the stock rom but it seems to be looking for a later rom than the one I have installed and keeps telling me I have the lastest and so wont flash.
So can I recover from this at all or have I just bricked my phone? Is there a way to FORCE the mobile upgrade tool to reflash the current rom rather than looking for an upgrade?
It seems that everything except the bootloader is intact so is there another tool I can use to restore the bootloader?
Any help would be greatly appreciated.

Looks like I managed to unbrick using a combination of SP Flash tool and an SPFT rom for the 4034X I found on the internet. will now try reflashing a different recovery tool.

O.K. so I think what is happening is an issue when unlocking the bootloader and not when flashing recovery.
This is what I did:-
1. Enabled developer mode.
2. Turned on usb debugging and unlocked bootloader oem
3. Rebooted phone, plugged in cable and accepted connection authorisation.
4. From windows typed adb reboot bootloader. Went into to fastboot.
5. Typed fastboot oem unlock, Pressed volume up on phone.
At this point I was put back in fastboot but none of the buttons worked and the phone looked like it had frozen. Was It wiping data at this point? There was no indication that it was doing anything.
I removed the battery and reinserted but when I restarted I got the same boot loop problem. Had to restore stock firmware AGAIN.
Am I doing something wrong?

Update: I managed to install caliv touch recovery without unlocking the bootloader by using the same sp flash tool I used to restore the stock rom. However, I cant install root. The recovery will only let me sideload and I could only find the chainfire SU binaries for sideload (SuperSU 2.78-SR1 and superSU 2.46). Both of these seem to flash ok using adb sideload with ctr recovery but the phone hangs at the boot logo. I also had superuser-r197 (ph's sueruser) but that wouldn't sideload.
So I now have a custom recovery but still can't root
Has anyone succesfully rooted the 4034X (UK)? If so, how?

Hi & welcome to xda-assist,
you can try to force the installation of supersu systemless by this step, chances are good that this will make it boot properly.
boot into twrp >go to the terminal > and type:
echo SYSTEMLESS=false>>/data/.supersu
Don't know if the recovery you use has this terminal option but it's very likely.
You can do additional a Google search on "force SuperSU systemless" to get more information / background information..
Good luck
Sent from my OnePlus 2 using XDA Labs

Thanks for your reply Sam.
I only read that after I had found a copy of a CM13 Rom that worked with The 4034X. I basically flashed superSU first then did a wipe, then installed the custom rom and google apps nano before downloading the supersu apk from google play and reinstalling. Now I have a rooted phone with a custom rom and am somewhat happier. The reason I wanted to root was to remove the bloatware that was taking up 1.5 GB of my already measly 2GB internal memory and this new ROM only takes up .5 GB.
I still have some pain. For example many of the Rom Toolbox Pro functions don't work and I think its because the system image seems protected and refuses to mount rw no matter what I do. Even issuing a remount command using the device name from cat /proc/mounts tells me the block device is read only. I also seem to be unable to verify if I have busybox or install it due to the same reason.
It also took me some time to work out that the boot animations weren't stored in /data/local or /system/media but to /data/system/theme.
This used to be so much easier in the days of ice cream sandwich and lollipop. Ah well!

Update:- Managed to flash busybox 1.26 using a flashable zip via adb sideload in Caliv Recovery (Caliv can't see my adopted storage for some reason).
I'm happy now! Would still like to have a rw system so I can remove some system apps I don't use but its no biggie.

PROBLEMS in installing TWRP and root (20a)

spent the last 3 weeks ( NO LIE ) trying every method under the sun to get my device rooted
easy recowvery
Hard Recowvery
manual ADB and flashing img
tot updates
kdz downgrades
basically everything
im not sure what else to do if its even possible at this point
Device details
tmobile locked LG G5 (h830)
OEM unlocked
its on 20a firmware ( coming from 20i )
ive rooted and installed twrp on may phones so i have a vast knowledge of these things
a few observations are
phone seems like its rewriting stock recovery on each reboot
fastboot won't accept any commands, i get "writing 'recovery'...FAILED (remote: unknown command)"
both hard recowvery and easy recowvery work up to the part of twrp install then it reboots to nothing
FINAL NOTE
im wondering if t-mobile is blocking the fastboot commands since im on temp unlock via device unlock app
if thats not a thing idk whats wrong im hoping one of you great minds can help this poor soul

Anyone?

thanks for replying ,
yes i did
its greyed out now but its been off
the fastboot commands says its unlocked as well

Did you make sure to download the recovery image and put in the root directory of the device storage and rename it recovery? If not then non of the recowvery methods will work. Also twrp needs to be the newest image. When using easy recowvery you should hit option 5 and enter then option 7 and enter and then option 0 and enter then option 2 and enter. Select y for yes when prompted and let the program do its thing. You should be prompted to boot into recovery at the end and it will go into tarp recovery. Hit cancel when it asks for password. Then go to wipe and format. After formatted, you need to install no-opt enc or root and then you're done. If you want to update all you have to do is get latest firmware from this forum. Also' if you update you need to also re flash no opt enc or root again and I also delete recovery from boot.p file in recovery. Should be good to go!

providing an update
Ive just tried everything listed in you post specifically and failed , so i tried like 2 more time ,
it reboots into stock recovery so still no TWRP ,
boot loader is unlocked , cause i just checked again , and its still not accepting any commands

Adb flash commands do not work for the lg g5... You have to root with either easy recowvery or hard recowvery. You have to be on 20a firmware.

thanks for reply;
none of those work for me either, I've been trying all this time
it says its successful in deploying commands, but when it restarts I see the LG logo two times, then it boots back up
( i assume its rewriting recovery there )

Can you explain the exact process you are trying? It is kinda hard to diagnose the issue without knowing the full process you are trying. I have rooted several lg g5 phones with the autorecowvery tool.

I had the same issue after returning from 20k to 20a. I didn't have this problem doing the same from 20f. T-Mobile might've introduced some security kink at 20i that sticks across updates. I was only able to flash twrp after flashing 20a with UPPERCUT to enter LGUP, booting into 20a, allowing debug in developer options, then running easyrecowvery with verification disabled (press 5 for advanced options, then 7 I think, then 0 to return to main menu, then 1 or 2). With verification enabled, easyrecowvery will just take you to the non-existent Android recovery screen and leave you there. I think that's where you're stuck??

well lets use Autorecowvery for example
ive exhausted all options there and Ive gotten the success messages , does its fancy restarts and success messages all around , but when it restarts to install the "no-verity-opt-encrypt" it reboots and comes right back to android . ( note it reboots 2 times at this point , so i know its rewriting stock recovery )
see below

It seems like you have a recovery flash. Have you tried adv reboot recovery? If not then you need to try that. You can also use hardware combination to get into recovery. You have to select yes both times and it will reboot to recovery. If it doesn't then start over with the auto recowvery. Also, it is very important that you download twrp and copy it to your internal storage on the root. Also, once it is there you have to name it to recovery. Don't use the .img when renaming it because you end up with recovery.img.img... Sometimes it takes a few tries on the recowvery method... Hope this helps!

well ive used
- "adb reboot recovery"
- hardware keys ( whenever i do this it wipes the phone ) , so i wont be trying that much cause i have stuff on it now , phones not encrypted tho
ive tried all 4 versions of twrp and renamed them all , countless times ive tried everything ive searched and read

When you first get into TWRP for the very first time, I believe it is a must to "FORMAT DATA" before you flash supersu and 'no-verify' zips

I know this might sound silly, but have you extracted the twrp file and then renamed it to recovery? Have you tried downloading on your phone and then extracting it on your phone and then renaming it? After I looked at the image you shared it seems like the flash seems to have an error and the only thing that makes any sense to me is a bad download of twrp or an unextracted version. I've ran into that error before and it drove me nuts until I figured it out...

used adb to push and rename to phone

still having challenges with this
do you think its a dead case guys

OP isn't the only one with this hair-pulling problem...I too downgraded a new H830 from 20M (? I can't remember which one exactly since I've LG-Uppercutted 20A and troubleshooted this constant problem so many times now)---I get the exact same error as OP, also with the highly suspicious 'greyed-out OEM Unlock' (in the Developer Options of the Settings).
