Need help!! Cant root Android 7.0 NBD91P - Nexus 6 Q&A, Help & Troubleshooting

Hi all,
First of all i am not noob to flashing roms and kernels. I have been flashing rom/kernel since 2011 on different phones. But i never encounter this type of problem. On my N6 i cant get root on my stock rom(not debloated rom by tupac4u).I have tried different supersu zips(2.78, 2.78 SR3 and SR5) but no luck. What i did, went to recovery wipe everything except internal storage, reboot to bootloader, flashed latest factory image( which is NDB91P), setup my device, reboot into bootloader to flash recovery(because you loose twrp when you flash stock images), then flashed SuperSu (tried every versions) and i always get bootloop. Am i missing any step??

Lost TWRP and root after installing rom

Hey everyone
I've been using the XT1053 Retail US Stock Lollipop Flashable ZIP without issue for quite a while, but decided to update to the modded version 2. So I flashed it, xposed, and supersu again. Booted up, everything was okay. But then it said I needed to update my supersu binary and that I didn't have root, so I went to reboot into recovery and flash supersu once more.
However, now I can't access TWRP and it merely says "no command"
Should I just try installing TWRP again or is there a way to see if it's still installed? It's weird that this happened after flashing a rom
edit: reflashed twrp recovery img, back to normal. Can't explain what caused this though

[help] Regain TWRP on OOS4.0 Official with a mac

I've tried asking this question on other threads but no one is replying.
I have installed the official OOS4.0 through TWRP. I was on a CM13 ROM so I flashed the full 3.5.4 zip and then the 4.0 OTA directly after. Then I flashed SuperSU but I guess it didn't work because I don't have root access.
Now I lost access to TWRP as well. So I tried to reflash TWRP through my Mac and though the process runs smoothly, whenever I boot into recovery, it's still stock.
Is there anything I can do to regain TWRP access through a MacBook?

absolute cluster**** after attempting to move from 4.5.0 to 5.0

So... was tired of some miscellaneous issues with 4.5.0 (rooted w/ Magisk, TWRP recovery) and decided to finally jump to 5.0. Failed initially in TWRP (was using stock 3.1.xx), moved to the OOS internal upgrade option, and actually managed to boot into 5.0 (albeit stock recovery and no root) after that succeeded.
Powered off, connected to PC, fastboot flashed TWRP 3.1.1 blu spark, rebooted into recovery, reflashed blue spark img, flashed OnePlus3TOxygen_28_OTA_060_all_1711160447.zip (went fine AFAIK, "script succeeded, 1.0000"). Cleared Dalvik/cache, flashed SuperSU v2.82... and this is where things got weird. First, flashing SuperSU failed once at the point of compressing the ramdisk. rebooted into TWRP, tried again, and it finished without error messages. Wiped Dalvik/cache once more and rebooted. This time, I got a permanent boot where my OP3T appeared to freeze at the first OP logo on a black background and would go no further even after 10+ minutes. Swapped out my SuperSU zip with a download straight from their website, same frozen boot. Redownloaded OTA_060_all, same thing. Wiped dalvik/cache/system before each attempt, no luck.
Gave up, fastboot -w, reflashed TWRP blu spark, and now even just drying to flash the plain OTA_060 zip results in a "no OS installed" when I try to reboot. When I try to flash either Magisk v15 or SuperSU 2.82, TWRP freezes entirely in the first steps, crashes to a white notification icon, and requires a long power button hold to reboot. I am lost at this point. AFAIK, my OP3T is basically a blank, wiped slate, and I've never experienced full-on TWRP freezes while flashing before blu spark.
In the meantime, I've installed OTA_057 (4.5.1) instead, thankfully without a bootloop, but fully wiped any suggestions?
I've jumped from Nougat to Oreo too. These are my steps: while on nougat open the TWRP recovery (stock TWRP); MAKE A COMPLETE BACKUP; updated it to the latest version (3.2.1.0.- if you have it installed then there's no need for this step); complete wipe; install the OTA using USB OTG; boot to system; run the first setup; (now TWRP might got overwritten just reboot to recovery, if it reboots to TWRP great, move on, if not then reboot to system and install TWRP using ADB); reboot to TWRP recovery; flash Magisk 15 (or SuperSU, but I don't use it so I can't say if it works); flash kernel if you want; reboot to system; check if Magisk/SuperSU works and that's it. At this point I've made another complete backup just in case I skrew up something in the future. Hope I helped! Good luck!
Are you using supersu 2.82 SR5.
I had same problem with my 3T going from nougat to oreo.

Click to expand...
Click to collapse
Yep, I believe that's exactly the version I tried I eventually just gave up after doing the complete device wipe through fastboot commands, am now running 5.0 with no problems but have the stock recovery and am not rooted :/ Now I just need to make a backup and then I can mess around and try and find a root method that doesn't basically soft brick my phone...
Even I am running OOS 5.0
The way I rooted is:
Flashed oos 5.0 using TWRP (https://forum.xda-developers.com/devdb/project/dl/?id=27381&task=get)
Boot normally
Reboot to TWRP, flash TWRP using fastboot if you find stock recovery. Then boot to TWRP.
After you in the TWRP recovery, flash superSU 2.82 SR5
Then flash suhide (it helps you hide root from apps which are a bit finicky about root).
This works for me.

I just followed these steps coming from rooted 4.5.1 and worked perfectly.

Flash Rom and Root unsucessful, after SuperSu/Magisk boot directly into TWRP

As the title says:
I unlocked my bootloader
flashed TWRP, flashed Google Pixel Experience rom but then when I flash either SuperSU or Magisk (after the first try with SuperSu, I rebooted, wiped data, flashed the rom again and tried Magisk) the rom doesn't start after hitting reboot system, it directly boots into TWRP instead booting a rom.
Can someone help me?

Help with Magisk root Pixel 2 factory Android 9.0.0 installed

Hello,
I have been struggling to root my device. I have not wiped and rooted it in some time and now coming back to it again magisk keeps breaking my device.
I have clean flashed the latest android 9.0.0 build. I have flashed TWRP custom recovery 3.3.0 successfully. I have tried to flash magisk 3 times now and afterwards my phone wont boot. I originally used magisk manager to get the latest zip and patch my boot image. I then rebooted to to bootloader and ran fast boot flash boot patched_Magisk.img. This wiped out my twrp recovery and my phone wouldn't boot, i couldn't get back into twrp recovery. I reflashed latest 9.0 build and wiped everything. I flashed twrp again and tried to flash Magisk 20.0 from recovery. It was successful but again i couldn't boot into my phone and it eventually restarted back into recovery which i still had twrp this time. I then tried it again with 19.3 and the same thing happened. can anyone tell me what is going on here? What am I missing? I have been having reflash factory 9.0 build each time just to get it to remove the patched boot image and boot up again.
Was either the TWRP version or the two check boxes it has now to install twrp app as system. Installed 3.2.3-1 and didnt install the twrp app through the recovery check boxes and it worked.
