Hi,
I've rooted my S10 Exynos. Now, my USB port doesn't work after it detected moisture (which can't be...the phone was completely dry, but this is another topic).
I can charge via USB but data and fast charging don't work anymore.
Now I wanted to send it to my provider and before this I thought it's better to unroot and relock the bootloader, eventhough KNOX is marked.
Is there anyway to do this without USB?
Greetings,
Jannomag
Just reboot without using combo key, u should be unroot and hope they dont see the bootloader warning screen.
Can you boot in download mode? You can enable bootloader lock but you need to factory reset after

Relocking with a modified recovery partition isn't possible, or is it?
I wanted to completely remove Magisk and return to stock firmware.

Relock your phone again. Flash now the stock recovery. Then it's alright.
i think you didnt understand what im saying bro. i unroot and relocked already after relocking my phone got stock in eRecovery and i cant get out even unlocking again etc. still im stock
To complete your initial operation, you need the recovery. From your description, I see you had TWRP before. That will not do. Flashing in the bootloader you can only unlock with OEM. So, relock, recovery flash and then lock again.

how sir? i dont get what you mean... can you please show me a tutorial?
So I wrote it in my root tutorial:
Button combinations:
Fastboot Mode: Vol.- and Power with PC connection
Recovery: Vol. + and Power without PC connection
eRecovery: Vol. + and Power with PC connection
All system reboots always without PC connection.
Without PC connection means that the cable from the PRA is separated, only from the PC is not sufficient.

With the PC program "DC Phönix" you can save it again. Unfortunately I do not know about it. Google knows more.

have you tried going into your stock recovery and just do a regular factory reset?
@jorge3687: First try a factory reset as suggested by Arju. If that doesn't work, sideload an OTA image to restore your device. The OTA images don't require an unlocked bootloader.
Hi, guys. Yesterday I decided to change my phone's firmware, so I flashed a LineageOS ROM. Of course, I have unlocked the bootloader. And everything was fine. But I always wanted to use Android Pay, so I've decided to relock bootloader to make it work. And now I have so called "Red State":
"Your device has failed verification and may not work properly".
And then, the loading stops. No effect. Just this screen.
But the main problem is that I don't have any access neither to recovery, erecovery or fastboot.
Any key combination makes no good, the phone just boots to this screen.
I've tried to drain the phone's battery and plug it into computer, but it didn't make any good.
Is there any way to recover my phone? Or it's already a hopeless brick? Please, help me, I've spent two whole days on it.
why you lock bootloader when it has wrong recovery? you should have had installed stock recovery before locking device.

you should do alot of research before using ADB and flashing things :/
Try connecting usb to phone (don't connect with pc yet)
Press volume up button
Now connect to pc.
See if u are able to boot to fastboot.
Unlock BL, and your phone will boot to recovery on its own
Reboot

If I good remember for fastboot is vol down

Hello everybody,
I have a P9 that mounted twrp and magisk.
Needing safetynet pass, i decided to make a factory reset of my phone and to try again the rooting. Unfortunately i discover that Huawei had blocked the bootloader generator of codes and now i have a phone, that is switching ON, but missing a lot of apps (calculator, clock, recording voice, etc...).
Also commands like *#*#2845679#*#* to try update from there not working (not appears the hidden menu)
I tried to restore (finding my exact firmware) via dload but everytime i get error at 5%. Via OTA update same errors.. Now i have the phone in Bootloader LOCKED.
Can someone helps me to install again the full stock firmware in my phone. Thank you so much

Before Factory resetting you had to uninstall Magisk and to flash stock Recovery...
You can't apply DLOAD to builds that are not FulOTA_MF_PV (and most new builds are no more PV)...
Since you prevoously had TWRP, you did have Bootloader unlocked - just use the same code (you had to save it when you obtained it from Huawei) and unlock the Bootloader again.
If you didn't save Bootloader, this time you will have to buy 4 Euros credit and get it from DC-unlocker

If you are on Nougat, when you buy the code and unlock Bootloader, then flash TWRP and use HWOTA method to recover stock ROM
https://forum.xda-developers.com/p9/development/rom-huawei-p9-magicrainbow-v4-t3759292/
If you never ever want to root, then you could try to save 4 Euros (not unlocking Bootlader) and
a) Settings / Advanced Settoings / Backup and Reset / Factory reset and accept to Wipe Inetrnal memory
b) Boot to EMUI Recovery (switch off, boot by pressing Vol+ and Pow) and choose Factory reset
But not sure would it be able completely restore stock ROM (apps you are missing).
Also c) Switch off, connect by USB to charger, boot by Vol+ and Power, it should boot to Huawei eRecovery. Then download (over WiFi) and reinstall stock.
But I will prefer getting Bootloader code and then using HWOTA.
When you have unlocked Bootloader, if things go wrong, you have more options to unbrick the phone if it becomes necessary

I'm looking to relock my bootloader as the fingerprint scanner has stopped working so need to return the phone, but every time I try and do this I see the above error. Has anybody seen this before?

Also had this. Update via otg USB and should restore the phone including bootloader lock

Root type is risk means you modified the system (custom recovery, editing system files like build.prop etc)
Wouldn't relocking signify that you have modified your phone? Ie: relocked instead of locked?
End result. Warranty is void?
Not 100% just something that's happened on other phones.
Could it be the firmware you're on?? Have your tried flashing an updated firmware??
There's a solution. Revert back to stock. Factory reset via recovery mode. Power off. Boot into bootloader. Fastboot oem relock UNLOCKCODE
But it's better to flash firmware via usb otg. You'll het bl status locked automatically.
