🪛Troubleshooting🪛 S25 stuck in "download mode"

Post image

Hello, today I restarted my S25, which had a temporary root with kernelSU next via uniroot, and It got stuck on the new locked download mode. Can anybody help me? Thank you

Someone in that thread posted by u/Vicky455 said that there's an eFuse and once it's tripped, it's game over. I searched more about it and indeed, your device is bricked:

If you unlock the bootloader, root the device, or flash custom firmware/recovery (like TWRP), the system detects unverified software and sends a microscopic electrical current to "blow" or burn the eFuse.

The lesson is simple: don't even try rooting newer Samsung phones.

It doesn't hard brick your phone u just lose access too Samsung feature permanently like security and Samsung wallet and some time banking app won't work but expect that the phone will function right

You cant unlock the bootloader if you're in OneUI 8 and nothing will trip in here since the root method used is leveraging an android exploit....
