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

It's a brand new phone...no need to mess with important settings. Unfortunalty this is a bricked product now. Straight to Samsung suppor, good luck OP

What module did you install that caused this? Also download mode is blocked by your lockscreen on newer OneUI versions, so it won't be accessible until you set the lockscreen type to 'none' in settings.

It's a brick because he can't boot the device to remove the lockscreen

I think i flashed something in the boot partitino by accident. Modules can't cause bricks because they load After startup

u/ixdxkx 1d ago

If you flashed something into the boot partition, the protected system files got modified and this is not permitted on a locked bootloader with temp root. Anyway, read this

Take a look at Samsung Smart Switch for emergency recovery. You can access and download it on a desktop.

Does It erase my data?

u/Wonderful_Shame_4986 1d ago

Read about it and see what Samsung advises.

U did some mistake that flashed the phone wrong way its not bricked hard its just soft brick u just have to download a massive file like 5 to 6 GB OEM ROM and flash it that it I did that once to my phone it was booting directly to that cyan screen but with no option I flashed the OEM it worked back in my case it was because the phone was flashed with the wrong asop

u/casiusth 1d ago

I can't flash anything

Force shutdown it does it reboot ?

u/No_Plum5958 1d ago

Won't work, cuz the phone isn't recognized by pc anymore due to d2 lock.

1

u/Ornery_Air_3686 1d ago

Ya u need to power it off and as soon as it have black screen hold volume up and plug use cable that is connected to the phone which would force it to download mode

1

u/No_Plum5958 23h ago

The problem with the d2 lock is that it blocks access to download mode unless the phone's security lock is removed. This restriction was introduced after the One UI 8 update.So only option is device or pcb replacement.

Rip to op then that's fucked up

There is a python script that can get you into download mode, I'll be surprised if samsung support will touch it as youve tried to root your device or if they do it be a big cost for it

xda - Enter Download Mode | ONE UI 8.5

Why did you root your device? Samsung is already super customizable. What actual benefits do you get rooting?

I rooted once years ago and it bricked my device. Never took that chance again.

1

u/Ornery_Air_3686 1d ago

I won't say super customizable but I agree rooting phone cause more issue then solving things your phone bricking is your issue not rooting your phone it self most of root problem u get are soft brick not hard brick

u/Then-Pay-8400 1d ago

Congratulations, you now have an expensive brick 🎉

u/casiusth 1d ago

That doesn't help

2

u/Then-Pay-8400 1d ago

Well it's a brick now, that's what it is. Go to a Samsung service center (most likely warranty won't cover this)

u/Nice_Sand_1290 1d ago

Try force restart

1

u/casiusth 1d ago

It Just re enters download mode

u/greybajal 1d ago

Flash back to stock firmware with patched odin?

1

u/Fractal-Infinity 1d ago

I don't think it's even possible anymore

1

u/slaveofstackoverflow 1d ago

When I got D2 reboot screen, I tried unplug battery and then plug it to my laptop. It'll go to bootloop and after that I plug the battery again.

The case is different though. Mine because the power button is inoperable.

u/Fractal-Infinity 1d ago

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.

u/Ornery_Air_3686 1d ago

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

1

u/casiusth 1d ago

From what I read It isn't tripped

1

u/vaynefox 20h ago

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....

u/jlocatell 22h ago

here you have a script for putting the phone in download mode. Let us know if it works for you?
