Lost Root on 7.1.2 - G Pad 8.3 Q&A, Help & Troubleshooting

I have the v500 on Lineage OS version 14.1-20170505-nightly-v500. I'm trying to update and noticed I lost root at some point. I have TWRP 2.8.6; and when I try to do anything in recovery, TWRP freezes, and I have to reboot. It's not bricked and I can boot fine, but it appears I lost root and cannot figure out when. I've flashed several versions of Lineage OS and this is the first time I'm having issues. Any help would be appreciated. Thanks!

I would try flashing the add on SU zip, but I don't know how you'd do it if TWRP doesn't work.

I tried to install the add on su zip using sideload and when I try to start sideload using adb in TWRP, the device disconnects from adb. I saw where people lost root when they first installed LineageOS, but got it back with the next update. TWRP cannot backup, install, wipe, or sideload (via advanced). It's an interesting predicament. I've unbricked devices easier than trying to fix this.

Rooting Problems

Hey guys I had a couple questions regarding rooting the opportunity Find 7a. First off I have ColorOS v 2.1.5i and everytime I try to install TWRP onto it nothing happens, even though the computer says it has been flashed successfully. I restart my phone into recovery mode and the oppo recovery is still there. You guys have any ideas?
Also when I had the older version of colorOS, I could install TWRP but then SuperSU would never work. It kept saying the binaries weren't installed properly. Any ideas on that ?
Your guys help would be appreciated since I really wna root this phone
Thanks
Try fastboot boot nameofrecovery.img it should boot directly into twrp then
I couldn't root my phone in Color Os 2.0.8i untill i reflashed the rom and installed latest twrp then it asked me for root and i pressed ok.
Yea I tried what jthatch12 told me do and it worked and superSu finally installed properly

Pixel C OTA using Flashfire - stuck on "waiting for fastboot command"

I have a Pixel C, rooted using the Nexus Rootkit, TWRP and SuperSU.
All was fine and was on build N2G48C.
I had an OTA notification for Oreo, so I downloaded the OPR6.170623.010 Oreo OTA file, and used FlashFire to apply this.
Now everytime it reboots it goes past the Google logo, then to the "waiting for fastboot command" screen. I've tried rebooting to Recovery and I get the same thing!
Google didn't seem to help, so please can anyone else help?
I was manually flashing rather then using flashfire, but I was getting the same problem. First, flash just the stock room (no root or TWRP) and check that it boots. Mine would, but every time I tried to flash TWRP, it would bootloop to fastboot.
You may want to download the full rom, not just the ota. You can modify the flash batch file to not wipe the tablet, or just flash the components.
What was finally successful for me was to flash TWRP and NOT let it finalize. It should ask if you want to mount R/W so it can keep the rom from overwriting the recovery. I told it no, then flashed the Magisk zip for root. I haven't tested SuperSU, but just replace it here to try. This got me a proper boot to Oreo, with Magisk working correctly.
If I understand it right, and I haven't booted to recovery to check, the rom will likely have overwritten TWRP. Worst case, I have to reflash recovery whenever I want to do a backup or update my rom, but that isn't something I do often on this tablet.

Can't root Oreo (Magisk) or flash TWRP

I just changed from Android Nougat to Oreo flashing the latest build from Google (8.1.0, OPM3.171019.013, Jan 2018).
I used Nexus Root Toolkit for that, including Wipe.
All is fine with that, but I want Root access, prefering Magisk.
For that I'd need TWRP, but I seem unable to flash it with NRT (doesnt' update, TWRP 3.0.0.2, version to old?).
Well, it boots into that TWRP but it doesn't stick.
I also tried to flash the Magisk.zip via NRT directly, but didnt't work either.
As it seems I need Root to flash TWRP (using TWRP Manager) but I apparently also need TWRP to flash Root?
Please help me out here, I now fear to make a mistake with "me trying stuff".
(Like using that temporary older TWRP and installing latest Magisk, if that works, hoping it sticks, installing TWRP after that via TWRP Offical App)
Forget NRT (Nexus Root Toolkit) and just manually flash the recovery...
Download the current version here: https://dl.twrp.me/bullhead/twrp-3.2.1-0-bullhead.img.html
Boot the phone to the bootloader by holding Volume down while booting, or using ADB while the phone is running "adb reboot-bootloader"
Flash recovery with Fastboot: "fastboot flash recovery twrp-3.2.1-0-bullhead.img"
Easy peasy.....

Adding onto the above comment, make sure to use Magisk 14.0 or newer on Android 8.1.

Thank you, that was really quick and also worked quickly.
Magisk root now also functions, I am happy so far.

Lost root. How do I regain it?

Hi guys it's been a while since I've rooted any devices but decided to root my LG G PAD 8.3 (V500), since it is so outdated. I'm gonna go over exactly what I did on how I got here to better understand. Sorry in advance for the long winded post.
-Anyway, I had to downgrade to 4.2.2 by using the LG Flash Tool 2014.
-Then, I rooted my device by running root.bat Also, I had SuperSU when I rooted.
-After rooting, I installed TWRP via the play store, downloaded the most recent twrp.img and flashed it via the app. It took me forever to get to recovery by pressing power+volume down and then pressing power+volume down+volume up. But after what felt like 20+ tries, I got to TWRP recovery.
-I wiped my phone and flashed the most recent Lineage ROM. Unfortunately, after flashing the ROM, I could not flash GApps because it rebooted to the ROM after flashing. TWRP let me know that I had to update TWRP and since I did not have the play store and I was once again having trouble getting into recovery, I downloaded the most recent TWRP apk.
-When trying to open the apk, it gave me a "can't open file" message which I didn't understand why. After rebooting, for some reason, it then let me run the TWRP apk and installed the TWRP app. This is when I found out that I was no longer rooted because TWRP notified me. I double checked with root checker and indeed I was no longer rooted. I have no idea when or how that happened.
-Again, I couldn't get into TWRP recovery until I plugged in my phone to my PC and for whatever reason, it helped me get into recovery. I wiped the phone and proceeded to flash Lineage and GApps.
-I read that by flashing SuperSu I may regain root, so downloaded an updated SuperSu, went into recovery and flashed SuperSu. When rebooting, the LG screen came up with a message at the top left corner reading "secure booting error! Boot certification verify". At that point, I was in a bootloop and had to go into recovery, wipe and flash again minus supersu. So I am now on Lineage with GApps and no root.
How do I regain root? And anyone know how I was able to lose it? Back in the day when I was into flashing, I never had these problems and never lost root out of nowhere like this.
Also, if I wanted to get back to stock LG 4.2.2, how would I go about that? I know that currently, I can't use the LG Flash Tool 2014 because my current ROM does not have a USB Software option in order for the tool to recognize the tablet.
Any help would be greatly appreciated, thank you.

OP7 Pro does not boot after installing OTA from TWRP

Good evening. First of all, thank you for your help.
I have a problem, and that is that I have bricked my terminal. I have installed TWRP 3.5.2 by Nebrassy and I am trying to install the OTA 21.E.38 (11.0.2.1 GM21BA).
When it finishes installing, the terminal just boots into recovery. I've tried installing Magisk but it doesn't seem to be the problem. I don't know what else to do.
What could I try so I don't lose all my data?
