[HOW TO] Fastboot on LGP500

[marioemp2k7]

I don't think you can with LGMDP. Maybe with another service app + box or maybe you can do something with fastboot itself.

Thanks. I had a pretty good feeling that it couldn't and there probably isn't a well known way.

Hey guys I'm from the optimus v section. I've got one of the early versions of the optimus v with the unlocked bootloader and fastboot access but no key combo. I was gonna start some tests to try to compile the bootloader from source and flash it to my device.
I'm wondering if the lg program backs up the bootloader and the radio image?

They are in the kdz files, but if things go wrong... Don't know if you can flash the old ones back.

Unfortunately our kdz file is corrupt so it's a no go on that.

@Mur4ik or marioemp2k7

there isn't as much info on making the bootloader as I believe there should be. But what I'm getting is that I use git to clone
https://www.codeaurora.org/gitweb/quic/la//kernel/lk.git

(I already have the android source code)

then I add a key mapping, screen drivers, and rom partition setup.

Is the bootloaders source code that was made for the p500 somewhere so I can reference this?

1. Please download this (or from here) file and unzip it in to any folder.

2. Start LGMDP 1.5 tool with the phone connected (you need to have USB drivers installed) and click on Select Port

3. A separate window should appear like the one below

Just click connect

4. Another window will take shape (LGE Mobile security) with lots of options (links)

Click on the first upper right Browse and select the folder in with you have unzipped the files. You will get some errors that some image, table or headers are missing. Just click OK and in the end everything that should remain selected is Partition Table, APPSBL Image Header and APPSBL Image.
Now just close the window (click on x)

5. Now you are back on the main window and here you'll have to click on Download

6. You are almost done and from now on everything should go on automatically.

NV Backup

Autorestart in Emergency\Download mode and upgrade the files (you selected on step 4)

NV Restore (the last step) Do not disconnect the USB cable until the restore is done

Wait for the phone to restart in normal mode (your current rom).
That should be everything you need to do to get fastboot enabled.

I follow this and in step Autorestart in Emergency stop the proccess and ask to disconect and restore. :crying:
