My Nexus 7 currently has SuperSU installed, this was done after using Nexus Root Toolkit (Wugfresh) to install TWRP. From what I have read I have to reinstall the stock boot.img. I tried to this via TWRP and it hosed my startup. I was able to recover by using NRT via my pc. The first time I tried installing the boot.img, I basically unpacked boot.img and then flashed it with twrp. When I rebooted, I would just see the google logo and lock at the bottom.
Phone is unlocked and rooted currently. Any point me into the right direction of why I couldn't uninstall superSU?

You would fash your boot.img via fastboot.
fastboot flash boot boot.img

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.
I followed the instructions in the Internet in order to root my phone. I unlocked my bootloader and downloaded TWRP recovery. I flashed the supersu zip. Up to this, everything seems to be ok so I rebooted my device. It started to reboot but stuck on Google screen…
And now I dicide to flash factory image.
I get my phone back to recovery mode. I push the factory image into my Nexus 5X through adb and install the zip in TWRP. But it failed.
Is the problem about sth crashed in the /system, /bootloader, /recovery etc (idk?) ?
Can I wipe all and try to flash factory image?
Or any other solution?
Sorry for my bad English

Hi,
I recommend starting over. Factory images cannot be installed as a zip. Follow section 9 of my guide to flash the factory image using fastboot:
https://forum.xda-developers.com/showthread.php?t=3206930
OR you could install the full OTA image from Google below using ADB sideload in TWRP:
https://developers.google.com/android/ota
After which, I recommend using Magisk v. 15.3 to root your phone since it is actively maintained:

I have tried ADB sideload but it cannot detect my file
Or maybe I did sth wrong?
How to use ADB sideload then??

While in TWRP, you would select "ADB sideload" then you can follow the ADB sideload process from your computer. If it doesn't work, use the factory image and follow section 9 of my guide. Just do not flash the recovery image since you need to boot into TWRP to flash root again.

Thx a lot, it works!!!
So, I successfully unlocked the bootloader, then followed the instructions to install TWRP (which worked initially because I was able to access TWRP immediately after flashing). But how to I access it again once I'm back in the OS? When I click reboot to recovery it always reverts back to the stock recovery. I'm still on the stock OS, but I just assumed once TWRP was installed I could boot into it from there. What am I missing?
Solved the problem by getting Magisk installed and using Flashify app to flash the downloaded TWRP img.
@brGabriel just use the fastboot commands as mentioned by manojpawarsj12;
fastboot flash recovery twrp.img
Don't mess around with Flashify, it's dated and a good way to brick your phone...
I need to install Magisk in my phone but it seems that I need to reboot to fastboot. I already flashed TWRP using Odin but it seems that my phone does not support fastboot. Any help? Thanks
Hey guys,
Hope someone can help me or point me in the right direction, I am having serious issues trying to root my 1952-1.
I followed the guide in this post to install TWRP
https://forum.xda-developers.com/g7-play/how-to/how-to-successfully-install-twrp-g7-play-t3979701
I followed all the guidelines but when i tried rebooting to recovery I ended up in having TWRP splash screen bootlooping, but was still able to fastboot boot twrp.
I then flashed Magisk, it completed and then i booted the phone back up, no magisk was in the app drawer. So i installed the Magisk Manager apk and this told me I was not rooted. Repeated the whole thing and still the same result.
I have also tried patching the boot.img file using magisk but same as before the phone is not rooted, on top of this I have also clean flashed the stock rom but again still not rooted.
Anyone got any ideas ?
Yeah the rooting process can be a little bit frustrating. You will have to copy the original boot.img file to your phone. In the magisk app make sure you enable recovery mode. Then you can patch the boot.img file. Copy it back to your computer and flash it via fastboot. But there is a catch. The phone will be rooted only if you boot the phone through recovery.
