My X8 was rooted and unlocked bootloader. I know that I will lost my guarantee.
But I have problem with my LCD touchscreen. It's the hardware problem, not software. So, I think I can get my guarantee.
how SEC identify the rooted and unlocked phone?? Can I get my guarantee back??

Re-lock bootloader, flash stock firmware and send your phone to Sony

I read that re-locking a bootloader with a custom kernel installed would brick your phone, is that not correct? I belive the correct way would to be to reflash your phone to stock using SEUS and then lock the bootloader?
I'm not saying that eagleeyetom is wrong, I'm fairly new to this type of thing but I do remember the unlockbootloader guide stating not to relock bootloader with a custom Kernel installed as you'd brick the phone. Just trying to help

thanks for help.
my touchscreen is broken. I wanna change it to the new one.
I should relock my phone, right??
Are they check the software?? I think i've got the hardware problem..

Yeah, you're right. You should first flash stock kernel and then re-lock.

thanks.. i'll try it..

I think you have to unlock the Bootloader with adb.
If this wont work try to flash a other firmware.

try the fuse editing method, but it's likely your phone is permalocked by lg. they tend to do that when you send phone in for repairs.

Indeed, but if they did this to me I'd be demanding a new phone as they can't legally restrict you from unlocking the bootloader in the EU, especially once they put that option into the latest software versions.

Tks It worked

Frp locked

I cant unlock frp as It is grayed out the option of oem unlocking in the dev options
pls I need help
Model : LLD-L21
OS : KangVIP Rom (EMUI 8.0.0)
Bootloader Status : Unlocked
In fastboot it says
Phone Unlocked
FRP Locked

did u try dload method?

yes I tried dload
It did not work

I can't upload zipI will send u the file to unlock frp or you can find that file in telegram group of our device

That wont work...
Go to terminal in root mode and do
Code:
Setprop sys.oem_unlock_allowed 1
Than you can change the value and its not longer greyed out.

If that dosent work you can also follow the below procedure.
Relock your bootloader. Your phone will factory reset and boot. Then head to developer options and you will see oem unlock is not greyed out. Then just enable oem unlocking and unlock the bootloader. When you boot up again you will see that oem is greyed out but it'll be enabled. So you'll have unlocked fastboot and unlocked frp now.

I haven't gone that far. I've unlocked and then relocked.
Everything fine. I believe it's completely safe if you have complete stock firmware installed ie, stock rom, stock recovery, stock Kernal and all that stuff. Otherwise you'll end up in a loop. Guess I forgot that part sorry.
So I know this is someone else's thread but can you tell me if I relocked bootloader will the service center be able to know I'd unlocked before? I don't have the phone unlocked warning at boot. Just curious.

Some if not all bootloaders nowadays are not "locked" by the manufacturer using a code but are usually "locked" by employing a digital signature and/or a CID (carrier Id) hard coded into the OS. When we "unlock" a bootloader with a code we are simply using a routine written into the loader by the manufacturer to now ignore signatures and/or CIDs of the OS and this allows us to flash whatever we wish.
Sometimes upon unlocking using a code the DS/CID is erased/altered and cannot be retrieved, so not a good idea to relock an altered bootloader.
At least, that is my understanding of it.

That's too bad. Means we won't get back our waranty if we relock it ?. So thanks for the heads up . I'll be careful while unlocking it again (if ever).?

Not necessarily, I doubt if most service centres would bother delving that deep, but maybe some would.

Thanks for your quick reply but do you know any way to get back CID/DS

No, but I haven't delved that deeply into Huaweis bootloaders, but I NEVER attempt to re-lock them.

P10 not turning on after update!!!

Hello.
i have a Huawei P10. [VTR-L29 9.0.1.159(C185E3R1P9)]. I updated it using hisuite and firmware finder via erecovery 2 weeks ago, then recently i tried to check for updates in hisuite, an update is available, with the same build number(developer) with size of 880mb and i updated it, after completion of update, phone restarts, verify installation packages and proceed with update installing, after 99% phone restarts again and not turning on itself, i tried manually turning it on, not successful. so I tried plugging it in my computer, hisuite detects it, and system recovery is the only option. i tried but it failed, and should be taken to the service center.
What should I do?
-my phone was purchased abroad
-warranty expired a year ago
-i dont have the box of it and the imei infos.
If anyone can help me, please I need it. THANKS

Hope that bootyloader still working, else there's a chance for you to get another phone.
If I had to go thru what you have today... I would try to flash Emui 9 based RR or Los just to revived while enjoying the pure android interface.
If all else fails... Go back to basic maybe there is a thing or two that you've missed

Can you get to the bootyloader or recovery? As long as bootyloader still working there's still a chance for revival.
You can try flash stock recovery & try to get it to flash the stock fw from it.

I have solution

I don't see any articles on for unpaid versions to unlock the bootloader. The only safe & easy is thru dcunlocker.

I spent roughly not more than 5usd for a code & that's about it. Nothing more... Now I'm happily unlocked that bootyloader :good:
I think the only ways is thru pc or with a small payment at the huawei service centre to get that firmware up and running again.

Redmi 9C bootloop issue

hello, i have a problem with my redmi 9c
my phone just started bootloping alone, i went to sleep and i woke up with my phone dead
the phone is stock, no root, no custom recovery and still with bootloader locked because i don't need features who need it, i can access fastboot but recovery is not posible to reach because Vol+/Power is useless, the phone do nothing pressing those buttons, only with Vol-/Power, so i can't make a factory reset or wipe data, the only thing what i did a couple of hours before the phone broke was change my security pattern (i don't think it's related anyway...), and it was 8 or 10 hours before the issue. sadly the phone warranty expired in january and i have nothing to do at this moment
the phone stops the bootloop after draining the battery, with the bootloader locked of course i'm unable to flash a stock rom, even with MiFlash
what could be the problem?
thanks! (and sorry for my bad english, spanish native here)

Hi, my first guess would be faulty hardware, for example a dead motherboard.
Is there any error when attempting to flash the Stock ROM with MiFlash? Afaik you should be able to flash Stock ROMs even with locked bootloader.

Hmm okay, yeah that sounds like it's preventing you from flashing simply because your bootloader is locked.
Which Stock ROM did you try? Same as the currently installed version or an older one?

I tried with the last available rom and the previous one, automatic updates were disabled, but I know I updated the phone after buying it
I don't remember if the phone was running last version...
MiFlash should let me flash the phone with the same installed ROM even with bootloader locked?

If you tried an older firmware, it's possible that it didn't flash because of Xiaomi's "Anti-Rollback" Feature which exists to prevent users from Downgrading.
But yes, it should let you flash the same version afaik.
What Region is your Device? On Locked Bootloader you can only flash Firmwares that are from the same Region. (For example Global or EEA)

Oh okay then.
If in the worse case nothing works, your last (paid) solution would probably be to contact one of these "Mi Auth" Guys on Telegram. They have acess to Authorized Accounts that are able to flash your Phone in EDL Mode (might need to open your phone to short test-points though)
I had to pay them about 20€ to get my old Mi 11 (which I sold a while ago) running again after it got stuck in EDL Mode. :/
