[Q] Bootloader Problem

Hello,
've got a little problem hope you can help me with this.
I have since 2 months my LG 4X HD and I've now decided to root it and unlock the bootloader. Got no problems with the root (did it with the AIO-Tool). When I tried to unlock the bootloader I realized that the AIO tool is only for versions EUR-XXX-& some 262-000. But since I live in Austria, and thus have the version 232-10, it would not work. That's why I first tried the app "Unlock".
While trying this I received error message "Unlock doesn't work anymore" and then the app crashed.
Next, I tried the version 40000000c0 and 40000000c8 with the Terminal.
've tried both variants. Trying 40000000c0 I got an error message, but unfortunately do not know more what it was. Then I looked in the hiddenmenu and saw that the bootloader was unlocked.
Now my problem: Any attempt to boot into the bootloader the phone will hang at the LG logo. I always have to press 10 seconds the power button until it restarts. In the home screen, I get normal, only the bootloader I get the problem mentioned. And I can't also boot into the recovery, even TWRP is installed. Volmue- + Power also dosen't help. It just boot normally into homescreen.
If someone is interested: Before I tried to unlock the bootloader've done a Nandroid backup. All drivers are installed correctly.
Does anyone know how to fix the problem with LG logo?
Information about phone:
Based band version: L6260_MODEM_SIC_02.1233.00
Kernel: 3.1.10
Build Nummber: JZO54K
Version: P88020c-232-10
Hope that was enough information.
Thank you!

Just flash v20a firmware so it would fix recovery and bootloader problems ,then check try to access the bootloader and see if it still gives you an option to unlock it.

If you've made a backup.. Surely you have a recovery? you need to do..
Turn on adb and do
adb reboot oem-unlock
You will either get a menu asking whether you want to unlock or it will come up with fastboot... If you get fastboot you have unlocked bootloader I think.. And then you can add the recovery by going to the directory with all your SDK stuff and put the TWRP image there...
Then it's
Fastboot flash recovery [name of recovery].img

I flashed a new firmware (austria) but it didnt helpt, it still hangs at the lg logo.
Also "adb reboot oem-unlock" didnt work. It just shows me the charging icon and turns off.
Any other ideas?
Thank You.
EDIT: I fixed the problem finally Just flashed the EuroOpen frimware and every thing went fine.
Thanks for the help.

Please help me purchased 15Euro DCPhoenix

Xiaomi Mi 5x Bricked, Need help.

Hello, today I tried to install a custom rom on my xiaomi mi5x, so I unloocked the bootloader and installed twrp, than I installed the android one rom .The problem was that I had to verify my gmail because it got locked, so I looked up a way to bypass that lock. I followed a youtube video on how to bypass that lock on android one, and now my phone has the following issue:
After booting I only see the MI logo for about a second, than it goes into black screen, same thing happens when I try to boot to recovery.
The only thing that works is fastboot.
Please help me!

Go into fastboot and write following command:
fastboot boot twrp.img

You will enter a recovery mode. There you could try a factory reset or flash a new ROM.\
If this wont` help, you could flash a new ROM via fastboot also.

We have the EXACT problem. Hope someone can help us.

Same problem... i'm getting desperate

I resolved it...
The problem is that the bootloader has locked again, you will need to remake the bootloader unlock process. So Download "mi flash unlock tool" again and use your account to unlock it
Sorry for my bad english... :s

Phone in Hard Brick mode

I was trying to install Arrow OS custom ROM to Motorola one power using TWRP. It got flashed, when I flashed the Gpps Rom with it, it didn't flashed and I rebooted the phone right there. The phone is now in a hard brick mode and is not responding to anything, is there anything I can do to fix it? Could you please guide me with the complete procedure?

You must use a blankflash to boot bootloader.BlankFlash available for
Moto One Power (Chef) https://mirrors.lolinet.com/firmware/moto/chef[/
.1 install Motorola drivers,2 install quallcom drivers for Motorola procesor(gsmusbdrivers.com/download/qualcomm-hs-usb-qdloader-9008-driver-64-bit-windows) .3 use flashbat in blankflash directory,4 press volume down and power on phone.5 connect phone with pc and proces will be starting.if your phone starting in bootloader mode ,you can flash stock room

Thank you for your help and response. I followed the steps as you mentioned. On step 3 when I run the Flashbat file, It gives the below error, and the phone never started
[112.478] ReadFile() failed, GetLastError()=0
[125.434] ReadFile() failed, GetLastError()=0

when blankflash starting you can release the wolume and power.try differrent usb port in pc.I have the same problem with custom roms,You see port com in device manager on pc?

It worked, but how did you know all this? Just spot on :good:

I tried this method but not working on my phone, xt1942-1. This is the Chinese version p30 note I got from AliExpress. I see the device in device manager as port 9008
Any help would be appreciated!

Hi,you are try change a port USB in PC?this method works,my phone is the same like your,Moto p30 note from aliexpress

Thanks, I tried all usb ports on my pc but same problem. Should we press power and volume down buttons after connecting to pc? Please help I just got this phone today and bricked right away ...
Also there are two blankfash versions on the link you provided which one to use?

Hi @dadm I could not get my SIM card detected in RR rom and tried to flash stock again. Now I am in a bootloop whatever I do. Which stock did you use to revert back? And is your SIM card detected?

I have a few questions if anyone could answer. I am looking to get hands on this phone but making sure everything goes as I expect.
1.Does any member have knowledge which of this Device variants (XT1942-1, XT1942-2, XT-942-3) qualify for "Unlocking Boot-loader" and which variant does not support unlocking. I am lookig for 4/64gb Chef.
2. Is there Any Custom Pie Rom with Solid stability + Efficient & Effective Kernel?
3. Does stock Motorola Camera app works 100% in a custom flashed Rom as it does in Stock Rom or we have to use Google Pixel Camera apps as an alternative?
4. Is there anyway to get back to stock image from Custom rom.
5. How to recover the device from a Hard Brick.
6. Not but least. How well this device performs while playing PUBG.

Phone flashing locked and stuck at fastboot mode
