Device not booting after flashing twrp. - Samsung Galaxy J7 Questions & Answers

The internal storage was empty (showing 0mb) after flashing twrp. So, I wiped and everything. Then, it showed but when I tried to boot to system, it boot looped.
I have flashed the stock firmware so it is back to normal.
The 2nd time I flashed a custom kernel before twrp and also flashed the no verity opt encrypt but this time when booting to system, it showed the Samsung logo and shut down. The internal storage was not mounted this time too.

Phone not booting

I have rooted my phone and installed CM 12.1. Yesterday I backed up my data using twrp and then tried to reboot it but it didn't. It just shows up the boot image and then turns off and then shows up the same. I tried to wipe data using twrp and install a fresh rom and but now i can't access twrp. On entering twrp, it shows just the image to twrp and then suddenly the phone tries to reboot.
I also tried to install CWM recovery and then tried to wipe data but it just stuck in wiping data for a long time.
Please help...:crying::crying:

TWRP keeps boot looping

Hi,
I had installed TWRP 2.8.5 on Galaxy Note 4. I did a factory data reset, and formatted all the system and the data partitions as my device was encrypted. I restarted my phone, and as expected it wouldn't be able to boot to an OS as I had formatted everything, but I was hoping to get into the recovery menu, but it just shows the TWRP splash image, and the screen switches off, it again activates shows a the splash image for a second and then goes blank, and does this again, it does not load into the recovery menu. I tried installing the recovery menu again via odin but experienced the same error. Can you please advise on what should be done?
Thank you

Accidently wiped /dev/block/sda, now won't get past boot logo

So i was trying to create a bootable usb for linux from my phone. I'm 90% sure my usb was mounted at /dev/block/sda, i did my "dd" command and unplugged the usb only to notice it was unchanged and my device was frozen. After powering off, i was brought directly to the download boot.
So first I tried flashing mu stock firmware, then i tried flashing Lineage Os with twrp. The boot logo just continues. I tried formatting with twrp, wiping cache with default recovery. I tried recovery. I just keep getting an error about EFS not mounting, but i thought that only affects radios/modems.
I don't know what to do Any ideas?

After flashing a new ROM, TWRP doesn't decrypt the internal storage

I'm sure that this problem was asked a bunch of times now, but I didn't find any reliable solution to this so far.
I wanted to move from LOS to Omnirom.
What I did:
Wipe cache/system/date
Flashed Omnirom
Flashed TWRP (blu_spark_v9.96)
Reboot to recovery
But unfortunately, what I saw is that all of my internal storage is encrypted, and I don't know how to decrypt it back to normal without wiping it all to start from scratch.
By this time I tried some various tries to revert it back to normal.
But... obviously, I kinda broke it.
What I mean is that I've got the "stuck TWRP logo" and accidentally deleted to boot partition (I've already recovered them back (A/B)) but until I'll manage to decrypt my files, I'm stuck with the stock recovery and can only boot to TWRP, but not flashing it.
My question is:
What should I do next in order to return my recovery to TWRP and boot to my custom ROM properly?

Not Able to reboot pocophone f1 with pixel ROM installed

Hi
I have installed pixel ROM through the TWRP recovery mode. After the installation of pixel ROM, I wanted to overclock my phone. Hence I went to the TWRP recovery mode and by mistake wiped the system and data. also gone for factory reset. Now my phone is not rebooting and showing the google symbol and kept on loading. I don't have any internal storage also in order to reinstall the pixel or stock ROM. Please suggest me any solution
Since you have TWRP as recovery, can't you just go to recovery and flash the system partition with your Pixel ROM again? You can use adb to transfer the ROM to your data partition while in TWRP, and flash it afterwards.
If you erase your system partition (erasing data is fine), your OS is gone and your phone surely cannot boot into an OS, but recovery is typically on another partition so it should still be there. You should try to find how to enter recovery mode with your phone, typically something like holding down Power and Volume Up/Down together during boot.
