[SOLVED] Bootloader unlock problem

Hello,
I was using EUR V10H firmware on my device and I upgraded to V20A_EUR leaked.
Then reboot and factory reset.
Then usb debuging mode activated and "adb reboot-bootloader" command.
Then rebooted and LG splash screen appears. Saying that "Running Factory Reset for the First Bootloader Unlock : : Please Wait..."
But nothing happens.What is the problem? Any idea?
Remove battery and restart the device, no problem.
NOTE : When I checked "Settings->About Phone->Software Info = P88020a-EUR-XXX

I check the video, there are 2 steps to unlock the device.
1. adb reboot-bootloader -> OK
2. fastboot oem unlock -> after reboot LG screen appears with top text. when I try to appy that command, waiting device...
Unknown USB device error has been occured but it should not be because all LG drivers has been installed on my machine (Win7 Pro X64)

There's a step in the middle of those two... Install that package that is inside of the unlock folder. Hope you didn't forgot about

After step 1, you should run the "CT_HsPhone_General_Drivers", before you procede .
Pay attention to the tutorial/guide/instructions inside of the "LGO4X-UNLOCK-BOOTLOADER" folder.

Connect the phone "OFF" to the PC while pressing vol- (S/W).
Maybe it unlocked already and you didn't notice.
It should appear "bootloader unlocked" on the "S/W" screen.

Thank you for the TWRP with other device, but new to HTC butterfly S.
Encounter some problem with data.ext.win and the win000 file with special permission Set UID and Set CID, which not allow me to copy to my PC or even using TWRP file manger to copy to external_sd card.
Also, does not allow me to backup to external_sd.
Please advise if i did something wrong.

yoongkw i didnt get your problem..explain what exactly you want to do...

Anyone tried installing busybox? I kept getting error and reboots.
Sent from my HTC Butterfly s using Tapatalk HD

Sorry. Posted this question in the wrong section.
Basically wanna copy out the phone's TWRP backup folder to PC to save up the stock unroot version.
And was not able to do that due to Set UID and CID in permission, something with the kernel security.

yes, i'm using it. the one problem i've had is not being able to backup the cache. nonetheless, i've backed up and restored ROMS on my my S using TWRP many times without issue.

I want to do the tutorial, but would like to backup my stock recovery first. Is it possible?

[Q] Motorola Razr I Does Not go past the Red Boot Logo.

Hey ,
I just turned off my Razr I as I normally would , and when I turned it on again it just did not go past the red Motorola logo,
It just got stuck there , I could not restart it , or turn it off , I did not root my phone or unlock the bootloader,
its all completely stock (4.1.2).
I tried and succeeded in going to fast boot, by volume down and power , but all I could do was turn off the phone.
I don't want to root or factory reset the phone because I cant lose the data , so what can I do?
I did not install any new apps , just a routine restart.

It's seems that something happen to yours system files. You could try reinstall system with rsd-lite but you must edit XML files, cause you will loose data and internal memory will be erased.

The phone is unrooted. The option to wipe cache is supposed to be in recovery but there is no recovery on this phone as its not rooted. Kindly explain as I am new to Razr I

Tried it twice (formatting the cache) but still the same problem.Thanks for the help so far, hope there are still other things to try.

Perhaps someone could explain that xml editing and using RDSlite. I would be really grateful.

First what firmware you have in your phone, 4.1.2 I think, but DE, GB or maybe some latin? And your phone was branded or not?
I am not sure but as i remember you could on locked bootloader use only system partition with fastboot command
Fastboot flash system
System file is originally signed by Motorola so it is possible I think

Yes the firmware is 4.1.2 GB and I got my phone from T-Mobile UK but in the settings it said GB Orange. There is no label of the network on the phone if that is of any help and I have Sim unlocked the phone.
Thanks

http://sbfdownload.droid-developers.org/smi/CFC_9.8.2I-50_SMI-26_S7_USASMIJBORAGB.xml.zip download it, extract it, there should be file system_signed.
- Download fastboot pack, i think you will find it on forum,
- put system_signed file in folder with fastboot, put it in c: for example c:\fastboot
- enter in to recovery push vol-down and power button until green light show, when green light will off relase only power button, then you will see fastboot menu of motorola.
- Connect phone to the pc, if you use rsd-lite before your computer should find out a drivers if not, you must download it and install in general subforum is topic called tools for noobs,
- use your cmd in windows and go to the fastboot folder, in cmd use command "c:" then "cd fastboot" then you should be in c:\fastboot
- in fastboot folder write: fastboot flash system system_signed
- on phone you should see some commands one of them is that 100MB is max, and file will be seperated for 100MB parts
- after installation just reboot the phone
As iam sure system_signed is orginally signed this method should work, but for sure please anybody agree with me or not Its not do anything with boot so it cant brick your phone
I forgot, your battery should be at least 50%

It's one of the "unlockable" models. Use the "unlock-relock" tool or the unlock script from the unlock guide.

If this helps,whenever I boot into recovery now,a red text saying LGE SECURITY ERROR: BOOT IMAGE or something like that

So you flashed a recovery before unlocking?

If your device doesn't boot at all, do a kdz reflash. If you can boot to the system, use one of the methods mentioned above; you only need root and USB debugging on to use it. If you don't have root but can't boot to recovery, try the "root many android" method from the index, that might do it. If it still fails, do a kdz reflash, then start again (root - unlock - recovery)

[Q] Stuck at 'this build is for development purposes only' cycle

Hello everyone,
as title says, im stuck on booting HTC Desire C device. HTC logo on white background with "this build is for development purposes only...", cycling over and over. Mistake i made is when i was using 'All-In-One-Kit-v2.0' i forgot to install CMW, flashed "boot900.img" wich is overclocking kernel, flashed it, powered off the device, turned it back on and got stuck there. Im struggling whole morning to get this done... searched whole google about this, tried to flash "recovery.img", flashing new ROMs, unfortunately, nothing has been done. Hopefully you could help me and i would really appreciate that. Im newbie here, my english is not that good soo..

Turn it off, press volume down key, and hold it with power until you get to fastboot. Then connect it to your PC, and flash a Cwm, and then lower frequency kernel...

Bump... anyone? Please?

Do you have a sync manager program installed? If so, uninstall it (it should leave the drivers installed) and try again, the sync manager identifies your handset and takes control so flashing gets interfered with
What version of Windows? (I've not read whole thread) Win7 upwards has driver install problems so search the forums/threads
Only use on USB 2.0 ....3.0 is a higher speed than our handsets are capable of
