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

After two Hard Bricks trying to Unlock, lost my Network(No service)

Hi all, im having one kind of a problem, me and my friend, have tried to unlock his x8 Bootloader, and i have search and saw the hard brick warning, and checked the device says 9w12 so i thought it was safe, and it wasnt, because the device didnt work after using Unlock method.
Now we have Jtaged it using a box and made it work, and everything was fine, untill he tried unlocking using Flash tool, and it said unlocking was ok, but it didnt actually work cuz he couldnt flash nA kernel after. and then his device went off again, so we had to jTag it again with a box to make it work,
Now its back to stock 2.1 and cant find service, it can see the networks but cannot get signal (no service), and i read a lot on that i gotta use SMEC 77727 or something to make it work, but its the same we used to get our device bricked, so any advice plz guys help?
1.Relock bootloader
2. Unlock bootloader with FLASHTOOL not with msm7227 tools.
First time when I unlock bootloader I unlock it with msm7227,but I didn't have signal. After 1-2month I see that bootloader can be unlocked by flashtool. I try unlock bl with flashtool and now I have signal and I really enjoying!

thanks for your response, can u tell me how to relock bootloader, my eyes are bleeing from searching and i dont wanna hard brick the x8 again sir. x(
Use x8toolbox
Also, using 1stools. first time i tired to unlock, it said SEMC SIMLOCK CERTIFICATE, but now it says NOT RECOGNIZED SIMLOCK CERTIFICATE.. what would this mean?
before i do anythign stupid now
That message will change back to original message when you relock..
It's the reason you get no carrier lock.
I downloaded x8tools, but its based on Cmd command line, not sure where to find a tutorial, im looking at the moment to find one

Just checked - Doesn't give instructions but it's rather simple anyway - just go for it man!
Flash tool gave me this error when trying to unlock: WARN - Cannot identify your SL. Aborting
also, pc companion cant recognize my mobile when i try to repair its software, whats up with that??
Did you relock the bootloader first using x8toolbox?
No, because i cant open it, everytime i click on x8tools.cmd it open and close, no idea why,,,, do u have IM (hotmail or so) im in trouble really might need the help

OK got ya.. We could do this over IM but it's good for future users with the same issue to see this thread and find a solution.
So let's go..
1: Don't double-click x8tools.cmd
2: Open MS Command Prompt and cd\ to the directory where you saved it. (Desktop is really handy)
3: Type x8tools.cmd into command prompt
4: Let the magic begin!
alright, here what i got:
starting x8toolbox.final . . .
'busybox' is not recognized as a
operable program or batch file.
did as u said, so whats next bro?

Have you adb installed/configured?
Ok managed to make it work,, let me see now..
I can only see unlock bootloader option, no relock, is relocking under unlocking section?

[Q] Revert to stock from cyanogendmod

Are you are using cm on v20x? Then making stock wouldn't recover your warranty cause you have surely unlocked bootloader, which can not be reverted. If you still want stock, then just do a kdz flash using KDZ flasher not LGFlashTool.
Here:-
http://forum.xda-developers.com/showthread.php?t=2069723
This will make full stock exept for Bootloader. Then just do a factory reset.
I hope you know, how to find correct firmware.

I guess that I need to flash original bootloader first to get S/W upgrade mode. In fastboot mode phone is not detected.
About bootloader, I can relock it. Also it depends on the laws of each country if I lost warranty by unlocking or not.

This not detected thing looks like a CM bug, happens to everyone maybe. Don't worry about that. Just open and reinsert the battery. S/W mode will work then. This happened for me too.
Can you please tell me, how to relock successfully? And can I unlock again after relocking?
Still no success in getting to S/W mode.

How "Finally"? Reinserting battery or flashing bootloader?
So, you are trying to relock? Please tell if you succeed.
S/W mode.
I'll send it into the service first with unlocked bootloader and only if it gets rejected I will try to lock.
I have some dust under the screen so it can be hardly affected by any software changes.

Relocking bootloader error - huawei p8 lite

Hello, my wifi on the phone is not working so I need to take my phone to the service center. But I unlocked bootloader. So I was trying to relock it back. I have a code and I found lot of guides... but I got error in fastboot cmd -> "root type is a risk". I dont know which ROM should I flash into the phone to get it working. I dont have root yet, becouse of reflashing a lot of times and I flashed orignial recovery back. So I dont have TWRP there. What I have to do to relock my bootloader??
Error in adb cmd after: - >>> fastboot oem relock *number* - >> ERROR: Root type is a risk.

I had problem with my WiFi adapter. My phone was also rooted and of course I had unlocked the bootloader. I took it over to the service center and although they told me that my guarantee was void, I left it, so they could inform me about the cost of repairing it. Finally they told me that it was hardware problem and they would replace my motherboard. Although it was rooted, I didn't pay anything.
Besides that, a friend of mine had a Huawei phone and got a problem. Because of they didn't have spare parts, they replaced it with another newer model.
I believe Huawei isn't strict over these matters.
Just head over to the service. It might take a month to get it back.
Sent using my Huawei P8 Lite Ale L21
If it's hardware problem you got repaired phone in warranty also if bootloader is unlocked

Even though its buyed from T-Mobile, so its not going straight to Huawei services? I had there this phone already one time, with this problem and I got a new one, this is for second time, but I didnt have unlocked bootloader first time :/ I also think that, they will not even look at bootloader, but still I dont want to loose guaranty.
So often fails the Wifi-chip? My phone is 8 month old and I wait for this issue every day No There should be phones on the market, where the wifi never dies. Or? Otherwise huawei has build really **** phone. Maybe it is my last one. It's not nice to know, that the day will come without wifi. That's really not funny to wait 4 weeks. Not not funny. Good luck!

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 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.

Ok so I just upgraded to android 11 and want to unlock the bootloader but while doing it through the app it says failed to unlock the device why is that?
Also I have never unlocked my device before it's the first time I'm trying to do so..
Do a backup of your data you don't wanna loose and flash raw file with A10 available here in ROG3 section. Then your unlock tool will work. After you unlock you can update and restore data. Bootloader remains open until you lock it again with abd or app.
