Device always booting into TWRP 2.6.30

I wanted to share my somewhat scary experience and how I resolved it.
It started when one day I wanted to flash an updated rom using TWRP so I rebooted into recovery and TWRP all of a sudden asked for a password.
To resolve the issue I had to ODIN an older version of TWRP, fix permissions and then reinstall 2.6.30.
This got me back into TWRP and I thought all was resolved.
I then proceeded proceeded to wipe everything and even format to ensure the device was clean. I flashed the rom w/o issue and it booted up fine. After I got it all running nicely I rebooted into TWRP to make a backup. The backup was successful.
I then rebooted to system (after backup completed) and the my phone froze on the loading screen. I pulled the battery and restarted the phone and it booted into recovery mode.
I thought maybe there was a permissions issue to I did a fix permissions and rebooted to system via TWRP. Phone still froze when booting. I pulled the battery again and again it powered up into recovery mode again. I decided to wipe everything again and install an older backup that was proven to be good (which I restored previously w/o issue). It restored and rebooted fine. Then I turned off the phone and turned it back on and the damn phone booted into recovery again @#[email protected]# Rebooting to system in TWRP causes the phone to freeze, Cold booting the device boots it into recovery. So I was essentially stuck once I installed anything if I ever had to reboot the phone.
The only solution that worked was to take the stock image (included stock recovery) and root.zip and flash that to the phone. After flashing it I had to go into the stock recovery as the phone still didn't boot properly. I didn't pay much attention but the stock recovery brought up a number of errors but I was able to chose an option (sorry I don't recall what) to fix them.
After it was fixed the phone booted up w/o issue and also rebooted w/o issue. All appeared to be back to normal.
So I went and flashed TWRP again through ODIN and restored my backup and all is back to normal.
As an FYI .. I grabbed the stock image from here :

Phone won't boot and can't use adb

I got unlocked, S-off and changed the CID to BS_US002 and flashed the latest available nandroid backup. It worked great until I went into TWRP recovery and selected "fix permission". The phone got stuck in a boot loop. I could still access it through adb, but then I made the mistake of thinking I could fix it through doing a factory reset. BIG MISTAKE. Now I can't access it with adb anymore. I can still get into bootloader and TWRP recovery, but when I restore the nandroid backup it still doesn't get past boot.
Any help please.

HTC one M9 won't boot.

I got an unlocked HTC one M9, (sim unlocked not bootloader unlocked), I unlocked my bootloader to prevent it from wiping my data later, installed TWRP, and installed superSU from TWRP and now my phone refuses to boot. I get the HTC logo, then it vibrates and dumps me back at the boot loader with...
reboot reason: 0x776655aa
message: RPM:APPS NS-WD!
I have absolutely no idea what is going on, I can't find reboot reasons anywhere and I'm stuck. Before doing the twrp and supersu install the phone booted to android just fine.
I used TWRP 2.8.7.2 and superSU 2.71
I have attempted to reflash the stock backup I took as soon as i got the device and it always causes the exact same error, I don't know what to do but I can't replace the phone.
Please any help is appreciated.

Ok, so I got the device to boot again by flashing only the boot partition and then wiping the cache before restart. But it returned to the exact same state when I tried to flash superSU again.
Am I using the wrong version of superSU? or should I not install it through TWRP?

Unable to boot after unlocking bootloader and installing TWRP

Yesterday I decided to root my Nexus 7 2013 Wifi running stock 6.0.1 (build MOB30X). I first unlocked the bootloader, then immediately after that I flashed TWRP (twrp-3.0.2-0-flo.img). When I booted up, it would got stuck on a loop with TWRP running OpenRecoveryScript, saying something about unable to mount /data and renaming something, then reboot into TWRP again.
I did some research and it seemed I had to use a multirom TWRP version instead, so I went ahead and flashed it. Now I can go into TWRP, but when booting up I got stuck in the booting animation (the four spinning circles)
How can I fix this?

Just run these two commands:
Code:
fastboot format cache
fastboot format userdata
Don't worry, you have lost all your data already while unlocking it.
The first boot and the booting animation will be initially longer than usual.
Incidentally, no need to use multirom-TWRP anymore because TWRP v3+ has been properly updated.

I actually solved this myself before k23m's reply by flashing the stock rom (MOB30X), then completed the initial setup, then reflashed TWRP (twrp-3.0.2-0-flo.img, not the multirom version). After that I booted up then restarted into recovery but then realized that TWRP had been wiped (only the android with the red triangle showing). So I re-flashed TWRP again and this time rebooted directly into recovery, and renamed the file recovery-from-boot.p into recovery-from-boot.backup. Then I flashed su and all went well.

Thank you for the hint!

Soft brick that won't quit

Was trying to update the supersu binary by installing the updated zip in recovery. On reboot it was stuck in a boot loop. First off nothing else worked, then fastboot worked and then 10 mins later twrp recovery started working. I tried to restore a backed up image but still got boot loop. Then tried to flash a rom I had on sdcard - still boot loopy. Tried to go the miflash tool root but couldn't get it to find the phone despite it appearing in explorer. Copied stock miui zip onto sc card from pc and installed but still same problem. Standard dalvik/cache wipe before and after each install. Now I'm struggling to get recovery up.
Help - haven't managed to totally brick something despite many years of tinkering. :/

PS. I can still get fastboot up. Now when I try to get recovery up the screen goes black and I have to reboot.
