Flashed TWRP on my Samsung — stuck on “error occurred while updating”

Hey everyone,
So I was trying to install TWRP on my Samsung Galaxy A15 using Odin. Everything seemed fine at first, but after flashing, my phone rebooted and got stuck on this weird screen that says:

“An error has occurred while updating the software.”

It’s been like that for hours now — it won’t power off, won’t go into recovery, and I’m scared it’s gonna get screen burn if it stays like this much longer. Holding Power + Volume Down + Bixby isn’t helping either.

Any idea how to fix this? And more importantly, is there any way to save my data? I had tons of photos and notes that weren’t backed up 😩

Thanks everyone. Gonna give the full firmware flash a try tonight. Hoping it boots at least once so I can recover my stuff. Appreciate all the tips

Just adding this..don’t keep it on that error screen for too long, it can cause AMOLED burn-in. Try forcing a reboot every few minutes while you prep your files for flashing.

Smart move. There’s PC-based Android data recovery software that works once the phone gets detected again — it can scan internal storage and help you save photos, videos, etc. before you mess with system files again.

Got it, I’ll try that battery trick. If I manage to bring it back, I’ll use recovery software to pull my data before I flash anything else again.

I’ve had this exact thing happen on an A7 after a failed TWRP flash. What worked for me: disconnect battery for 5 minutes (if you can open the phone safely), reconnect, then immediately boot to download mode and re-flash full firmware.

If you’ve already soft-bricked it and the PC still recognizes it under Odin mode, that’s a good sign. You can still get data back later. But if the flash fails completely and it doesn’t get detected, you’ll need to look into data recovery software that can scan bricked phones once they’re at least partially functional again.

Yeah, don’t flash just the recovery next time. Re-flash BL + AP + CP + CSC (not HOME_CSC though, that one wipes). If you’re lucky, it’ll boot back normally and your data should still be intact.

If it’s looping back to that error screen, it’s probably a corrupted bootloader or recovery partition. You’ll need to re-flash the full stock firmware through Odin again — not just TWRP.

You can get the official firmware from SamMobile or Frija Tool, depending on your region. Just make sure you match your phone’s model number exactly.

Tried that combo, but it just goes back to the same screen again after reboot. I can’t reach recovery or download mode.

Classic Odin soft brick situation. You basically interrupted the firmware flash or used a mismatched TWRP image. The phone isn’t dead though..it’s just in a fail safe state.

Try holding Power + Volume Down for around 10 seconds; it should force a restart. Then immediately go into Download Mode (Power + Vol Down + Bixby).
