S6-Tmobile-accidental SYSTEM clear; boots to black and white logo or to green Downl..

Originally Samsung S6 on T-mobile. Rooted without tripping KNOX with TWRP and unlocked. God sole from the net changed IMEI, accidently while clearing cache the SYSTEM folder was also checked.
State now:
KNOX at 0; FAP - locked; phone boots to black and white Samsung Galazy S6 screen - no color lines in upper left corner and stays on that screen.
Can boot to DOWNLOADING state, but attempt to ODIN sboot or stock OH firmware FAIL.
When booting to barcode - the original (i.e. bad) IMEI and serial shows.
I guess problem is with sboot ? What to do? Please help.

Fire tv boots to black screen after amazon logo.

I was just able to get what seems to be the last fire tv in amazons surplus through their prime now app. I set it up everything went fine then I clicked to update it and it did the normal update process until I looked up and saw a black screen. I unplugged the unit and replugged it and now all I get is amazon logo then black screen. Is there anyway to fix this I was really excited about having the last fire tv. Something I just discovered is that I can still connect wirelessly to the unit via adb.. I just restarted it. I dunno if this can help anything.

gpad 8.3 only boots into twrp, can't go into download mode

I had version v50020d, flashed twrp from the play store app I think. It's rooted. I did a factory reset and it got into twrp and never booted the system. I followed some tutorials for ota softbrick for g2 and some others and now it mounts data but everytime i reboot it, it seems to not mount system by default, so it boots into twrp. I wiped the system as some site told me and i think i messed it up. I flashed cm12 the september stable version. I seriously need your help. My gpads battery level is pretty low too. I really need to get it working again.

Device only boots to stock recovery - No CWM or TWRP

Hello! Although I've been using the forum and it's abundance of resources for years, this is my first post.
Feel free to correct me if you find any of my activity to be in conflict with forum rules or etiquette.

I've rooted my SM-T530 and flashed latest versions of both cwm and twrp recovery through ODIN, but I have the classic problem of only being able to boot into stock android recovery.

What I've tried so far:

Rebooting into recovery from ROM Manager (proper recovery version selected in options prior to rebooting, but failing with both cwm and twrp)

Booting into recovery mode with hardware buttons (Power+volume down and power+home+volume up)

Flashing recovery without reboot option checked in ODIN, hardware button rebooting, still goes into stock recovery

There is a method being reported as successful on other devices, but it involves dislocating the battery, and I can't do that on the T530 as it's got a non removable back cover.

Still, other people have flashed custom roms on this device, so it must be possible to do somehow.

If people are willing to guide me, I am willing to go through every step again and post results here, so that other users might find help in the thread if we ever work it out.

Desire 620 (not g) boots to logo, vibrates then restarts! Need serious help!!

Hey guys im in need of some serious help. I was just watching anime on my laptop when i decided to check my clash of clans. For some odd reason it kept crashing so i decided to restart it but it just went to the htc logo and restarted so i went to the recovery menu and did a factory reset. It showed a pic of the htc phone with a updating logo in the middle and after it was finished it rebooted and the same thing happened again. I then tried using the recovery option because it was the only choice i had left but that just showed a lack screen for a minute before showing a pic of my phone with a red triangle in the middle. Is my phone broken? I didnt do anything to it!! Please help!!
