Hello. I have a SM-G925F which i rooted and then installed TWRP recovery by following youtube and tutorials here. Everything works fine for an hour and then the phone suddenly stop responding with a frozen screen. I tried to reset it by holding Power and Vol -. It turned off just fine however, it did not respond after attempting to turn it on. I have a feeling that i somehow messed up my firmware or whatever during twrp installation.
Notes:
1. No response when charging
2. Not powering on
3. Nothing happens when i pressed V up + power, Vol down + power... etc.
4. Does not respond to USB Jig.
Hope someone could help me out.

I normally enter to recovery mode by pressing Power x4 then Vol +, but I accidentally pressed Vol- instead of Vol+ and it went black, I powered off and turned it on again, still black screen, not even Toshiba screen.
Removed the battery and inserted again, same issue, however my computer does detect it when I power the tablet on while the usb cable is connected, but asks drivers for APX.
Can someone help me with this? Is it recoverable?
Thank you.
Working
Forget it, puppet13th user helped me with his thread: http://forum.xda-developers.com/showthread.php?t=1458876
Thanks just the same.
So thanks to Netflix and its implementation of security net I wanted to install Magisk on my Z2.
Im running the stock 6.0 Rom which was just rooted with supersu.
My tab was charged 80+%
I uninstalled SuperSU, went to TWRP and flashed Magisk.
After flashing the screen stayed black. Nothing at all.
Long press power gives me one vibration after 3 seconds but nothing else.
Long press power & vol - gives me the same vibration
Long press power & vol + gives me nothing
Connecting the tab to the computer gives me nothing. No device recognised (no adb, no fastboot)
Connecting the tab to a charger has the LED blinking red.
Long pressing power makes the led turn solid (no blinking)
Power & vol - the same
Power & vol + nothing
Basically I seemed to somehow have turned my tab into a brick oO
I can't even get it to boot to twrp or fastboot
Atm I'm letting it charge just to see if that was an issue (I doubt it)
Otherwise the only thing I can think of is opening it and disconnecting the battery...maybe that will help?
Ok nevermind. I managed to get into flashmode and reflash. tab is now working again!
How did you get it to be recognized and reflash? I flashed mine after rooting and I get similar behavior to what you were getting. It will vibrate once if I press the power button, I can get it to turn the light blue if I hold the up volume and the power button while plugged in. The screen will not turn on at the Emma tool doesn't seem to recognize it.
Same Problem here.
@pseudoheld could you please provide some more info?
I tried to flash twrp and now my phone is stuck in a 5 second boot loop.
Fastboot and recovery can't be accessed at all no matter what combination I make. vol+ power, vol- power, both +- power, hold 40 secs 60secs (useless because phone reboots in 5 secs) , all tried. Every 5 seconds it just boot loops. Help me.. I have it for less than a week. Wanted to flash only because the stock rom was giving problems such as landscape and auto random reboots.
I even tried a script which said would wait in adb detect mode, that didn't work. Guess phone rebooted before my pc could detect it. Tried installing intelSOC method as suggested in another thread, the short reboot is tough to get by.
By the way, it's an umidigi china phone.
bump.. pls help!
Hi , let your battery to completely empty , press vol + and plug usb to see if phone goes into Fastboot mode if not try Vol - and plug usb .
Both didn't work. But thanks.

woke up in the morning my phone was turned off. So, i tried to charge it . then it went to fast-boot mode directly. I thought something was up and powered it off and tried to turn on but it got stuck on boot screen - I Thought(Just a Brick and i could reverse it)
Series of wrong steps:
1. i advanced wipe system,data,internal storage (I thought it would reset the phone :cyclops: ). but i realized that i delete everything later.
2.from twrp i directly went to fast-boot mode. But, my morning brain made me to poweroff the phone from fastboot.
3.Tried to go to fast-boot but accidentally i powered it on which started a boot-loop.
i cant shutdown the mobile or do anything .
i want to known whether can i still go to fast-boot mode or not.
if I could some how shutdown or go to fast-boot i could bring my mobile back to life
Please Help Me Out !!!!!!!!!!
EDIT :
i found the answer holding Vol Up + Down + Power buttons would force shutdown it.
You need to flash with stock rom , try to hold volume - and power while re booting
Not working
Hello,
as I wrote in this (now locked) thread, I installed Superior OS and got stuck in bootloop. I get "Galaxy S9+" screen followed by system bootanimation, which repeats itself indefinitely. It doesn't restart by itself, it just boots endlessly.
The problem here is that I can't access recovery or even download mode. I tried to restart (power + volume down) and then quickly press combination to access recovery or download mode. No luck. I couldn't even turn the damn phone off. I just kept restarting.
So I let it drain the battery hoping I could then power the phone on with correct key combination. I tried holding bixby button + volume down while inserting USB. It just started booting up to system with boot animation. I tried holding bixby + volume up, or even power + bixby + volume down. No luck either.
I got correct USB drivers installed, as I flashed the phone with Odin in the past. Odin recognizes phone while it sits on boot animation, but it won't start flashing. ADB or fastboot do not work on bootanimation, as the ROM is freshly installed. I presume it has ADB turned off by default...
I'll be grateful for any ideas and suggestions.
No escape , man. I tried all ( check this rom for galaxy note 9 )
Nice...
I went to service center, they said they can fix it for me. 40 euros for reflash (download mode isn't necessary), 100 euros for complete unbrick. I hope the unbrick isn't necessary and the bootloader is intact. I'll post with update.
