OK so phone was rooted with twrp installed. decided to update to latest ota 30b only I wiped and just flashed boot file and supersu without the actual rom. I know. now the phone goes straight into fastboot mode... I would think twrp is still installed but dont seem to be able to boot into it. I had adb and fastboot on my pc from before but havent used this in some time. if I try to open either of these the command window pops up and quickly closes.. What can I do ?.
new info: fadtboot is working in fact i have wrote a twrp recovery but still cant boot out of fastboot... adb device not listed. i reinstalled minimal adb and fastboot. help
Hello
As menitoned, my phone won't boot into TWRP, it does boot into Android 7.0 EMUI 5.0, can boot into revolutionary recovery, but no, not TWRP... Bootloader is unlocked! Please help
Are you certain it's not booting into TWRP? The reason I ask is I thought I couldn't boot into the custom recovery programme either: it kept loading EMUI, using the phone's buttons. In my case, ver.4.1.1
Have you tried booting via ADB commands? I had reloaded a stock update, then unlocked the bootloader for a second time, only find the same scenario. It wasn't until I tried rebooting with ADB that it actually loaded TWRP.
In case you aren't familiar with the commands. Install ADB Tools, then open a command window from the correct folder location, where ADB tools are installed. To check the PC recognises the device, use:
adb Devices
it should show the device's serial number {I think}. Then:
adb reboot recovery
it should reboot into recovery mode. If TWRP has been installed correctly, it should load into it. Otherwise...I don't have a clue what the issue is. All the best.
I installed TWRP custom recovery on my Nexus 6P. I was able to boot into it ONCE. When i next tried to enter Recovery, i get a screen showing the Android Robot and the following statement: NO COMMAND
I tried to re-install TWRP using adb twice, but the result is the same.
How can i either fix TWRP, or re-install the stock recovery
I am basically a beginner here, so any help would be appreciated
If you installed the stock system image and then booted into it, it likely automatically reinstalled stock recovery also. I don't know why it does that, but it does. This is why I usually just reinstall TWRP again after each monthly update is completed.
You should use fastboot to install the images, not adb. The command should look like:
fastboot flash recovery twrp.img
I think i just worded it wrong - I used the above command (fastboot flash recovery twrp.img) to install twrp, and then, when i couldn't get back into recovery (Power - Volume Up combo just lest to screen that stated "No Command".), i used the fastboot flash recovery twrp.imp twice to try to re-install TWRP, but it didn't work
I also downloaded the latest stock Oreo ROM, copied the recovery.img file, and used fastboot.flash.recovery.img to try to re-install the stock recovery, but that didn't work either
The once time that TWRP work, it asked it I wanted to use TWRP is read only, to twice i selected NO (don't know if this matters)
Any other suggestions to fix TWPR, or re-install the stock recovery image???
When you say it didn't work, can you expand on that? Was there an error or anything?

If you want TWRP to stick, you need to flash either SuperSU or magisk. The Android with the exclamation mark is what stock recovery looks like.
Once you have TWRP installed and wish to keep it, you don't need to flash stock recovery in the monthly update. Just boot into TWRP after flashing update and root again.

When the phone is turned on, it never progresses beyond the first screen. No error codes, it just does not proceed to boot up.
I had to buy a new phone (need it for business, but i given up on trying to install Resurrection Remix on the Nexus 6P, which was the reason I was trying to install TWPR and SuperSU. So far, I have only accomplished turning the phone into a brick door stop!!!

Use Magisk it's the better solution for root. Never had boot up issues with it just stock you have to boot once through before flashing. Custom ROMs you can flash right away.
So I seem to have wiped/formatted completely through TWRP and it wiped out the original stock rom, so I have absolutely no OS...
I can still get to bootloader and TWRP Recovery, but USB OTG won't mount no matter how many times I try to connect it (which I need to install the downloaded ROM)
I was hoping I could copy the rom via ADB command but it won't recognize the device with 'adb devices'. It does however recognize when I do "fastboot devices"
What should I do? I think since it wiped out the OS, my device no longer is able to run in USB Debugging mode... how could I load the ROM onto my device?
IF you download the WUG toolkit, you can flash the ROM .img files in Fastboot mode (Boot/System/Recovery/Cache etc).
Bear with me, I had an older version and maybe just my method but I had messed up the custom rom I had on so I went to put a new one on and wanted to update TWRP at same time.
I installed the new custom rom, then installed TWRP and correctly clicked recovery.
However now recovery just goes into fastboot mode, I went into the dev settings and put usb debugging on, authorised it but each time it goes into fastboot it is not recognised and when I reboot into phone usb debugging has been disabled.
So now I can't get into recovery to flash a new rom, nor can I put twrp on by fastboot.
Stuck at what to do
Using Havoc OS
Try booting into the recovery from fastboot
Boot into fastboot and type
Fastboot boot recovery.img (recovery.img is the file saved on your pc)
