Did you create a backup of your stock ROM before you flashed the custom ROM? If not, you should have. A prepared user always makes a backup via TWRP before making any kind of changes to the system and before flashing ROMs, that way they can restore the backup via TWRP if something goes wrong.
Can you boot into TWRP?

That is because you triggered Knox, you won't be able to flash anything custom now that Knox has been triggered. The firmware that you flashed, was it the same build number as what you had originally or is it a newer, updated firmware? If you flashed a newer firmware that has a bootloader that can't be unlocked, you will not be able to flash TWRP or custom ROMs.

[Q] loading stock firmware without screwing custom recovery

Hi... im currently running
CROMi-X v5.2.2, which is based on rom 10.6.1.27.5 with twrp 2.5.0.0 and my bootloader says is the one that came with us10.6.1.15.3-20130416...
To install omni kitkat, im been asked to have the latest bootloader, to avoid screwing up im planning on insalling the latest stock from asus...
However, each time i install a stock through twrp or cwr, the new image not only updates the bootloader and deletes all my data, but rewrites my recovery, for which then i have too reupload using fastboot to upload the recovery...
Is there any way to make sure i dont loose the recovery after flashing a stock firmware... or a way to flash the recovery from the recovery before rebooting after flashing the stock?
Thanks everyone!

Flashing the stock ROM reverts the tablet back to stock, so the recovery must go. Luckily, the bootloader you are on is compatible with the KitKat recovery (10.6.1.15.3) so you shouldnt have to flash the stock ROM at all. If you were on 10.6.1.8, you would have had to upgrade.

Asked the same question about my bootloader at the omni thread to be sure, if they say that it works too, will go ahead and give it a try

[Q] flashed Twrp 3.0.0.0 on S6 g920f Marshmallow

Hey, I flashed twrp 3.0.0 via odin on my s6 g920f 6.0.1 rooted device (custom kernel) and now I can't boot into recovery, my phone works well, also download mode, just recovery gives me Recovery is not seandroid enforcing and stuck there.
I know this message is normal and not concerning but it's still not booting into recovery, I flashed the wrong version?
Try reflashing stock 6.01 ROM via Odin. ?
latest official TWRP (3.0.2-0) does not support 6.0 bootloader, so that's why you are stuck on boot.
until a new fixed version is released, you can try to use 2 alternatives :
1. @arter97 version , thread here , download page here
2. idlekernel version , download page here

IDK.. my phone works pretty good, it still starts and no problem at all. only recovery isn't booting.
I don't want to format it and flash stock again just because of it.
djcristi said:
i heard that you need to flash custom kernel , that stock kernel cannot boot TWRP, because of 6.0.1 bootloader.
. I am on the same case now, looking for solution because i don't want to use custom kernel, just TWRP and root it using Supersu.

Actually I am running SpaceX MM kernel(auto root)... so twrp should be fine.
i edited my previous post, you have there solution.

Yeah and it worked. Also flashed xposed, when I installed greenify module it caused bootloops so I flashed xposed uninstaller, I guess no xposed for me

Samsung S4 SGH-I337 Safestrap not working rom

Hello everybody! I have a problem: I wanted to install custom ROM via Safestrap 3.71. I made all the wipe. But at the end of the installation, I get an error: set_metadata_recursive some changes failed. And so in each ROM. After that, ROM does not load: black screen after the logo Samung Custom. How to deal with this?

Was it a true custom ROM? Or was it a modified stock ROM?
If it was a custom ROM such as Cyanogenmod or LineageOS, that's the problem.
Safestrap is intended to be used with modified stock ROMs that are based on stock kernel, not CM, AOSP or Lineage based ROMs.
Typically, Safestrap is used on devices with locked bootloader, these devices can't use CM, AOSP or Lineage based ROMs, these ROMs are built to be flashed via custom recovery such as TWRP.
If you have an unlocked bootloader and you want to use custom ROMs then you'll have to flash TWRP then use TWRP to flash the ROM.
If your device does not have an unlocked bootloader but you want to use Safestrap then you need to install TouchWiz(TW)/stock based ROMs.
There is a difference.
Also, when using Safestrap, you have to leave the stock rom in one slot and place the new ROM in a different slot. You can't overwrite the existing stock ROM with the new ROM, that causes issues and the device won't boot.
You will probably have to flash your stock firmware via Odin and start over with root and flashing.

I was flashing the modified ROM on the stock kernel. I put in the recovery on slot-rom1. I tried to flash: CarHD, KushanROM, GOLDENEYE and Omega. And still it does not work out

Do you still have your original stock ROM in one of the slots? Or did you overwrite it? If you overwrite it, you messed up. As stated earlier, you'll probably have to flash the original stock firmware via Odin.

The stock slot remained intact. But if I take the kernel from OC3, then the device will also not boot up and the recovery will become non-working.
Send me the stock ROM for flashed the custom ROM through the Safestrap. And send me the version of the Safestrap for custom ROM
I understood what the problem is. I installed another ROM NB1 and it all worked for me.

On most android devices, you can't apply stock OTA updates on rooted devices or devices that have TWRP installed, stock updates require an unmodified system partition(meaning no root) and must have stock recovery because stock recovery is what actually flashes the update, TWRP cannot flash stock updates.
Do a Google search for:
"Return to stock (your model number)"
Or, you can try restoring a nandroid backup of your stock ROM if you ever created one in TWRP at any time before the update. Or you can try flashing a custom ROM for your specific device via TWRP.

If you can not into recovery or download mode, try to flash TWRP again.
Or flash back stock firmware if that does not work. Keep in mind to use Home_CSC to boot wipe your data.

Just flash stock firmware through odin again then boot back into download mode then flash TWRP and untick "Auto-Reboot" option then when flashing is done, boot into recovery manually to verify if TWRP is installed properly then you could boot back up to OS from TWRP it shouldn't loop if all went well. Also make sure that before you flashed TWRP, you enabled OEM Unlock and USB Debugging option in developer options.

It's fine , Flashing TWRP first time wipes your data thus you get bootloop. You just need to Flash a custom rom and evertything will he fine.

Yes since TWRP needs internal storage and data wipe to properly work with these partitions when coming from stock ROM but flashing a custom ROM after a clean wipe of the partitions should work fine.
HERE IS THE SOLUTION :
after flashing twrp with odin open twrp and format data after then there is a bug for j7 devices sd card won't work so u need a pc to transfer no verify encryption file to.internal storage here is the file or you can flash magisk 22.1 to disable keneral encryption
(THIS PROBLEM OCCURS BCZ AFTER FLASHING YOUR KENERAL FORCE ENCRYPT YOU TO NOT BOOT IN ROM BCZ OF SECURITY FLASH THIS FILE TO COMPRAMIZE KENERAL SECURITY )
Just Flash the custom rom you have downloaded.
Same thing happened to me when i flash recovery for the first time stucked at the bootlogo.
