[HOW TO] Fastboot on LGP500

[rotorto]

Any news on how to enable fastboot on this device?

EDIT: Here you can find instructions for enabling fastboot on your device. The key combo to enter fastboot mode is Home + Power. Thanks to marioemp2k7 and mik_os.

Hi, I too am interested in having fastboot on LGP500. Did anybody find a way?

 

[jtaylor63]

Yes please, is anybody working on that? Having fastboot disabled is such a pain in the ass...

 

[iancor]

Please enable fastboot on this phone

Its blocked at bootloader level. You guys need to fish for a pre-release rom that can be flashed via lg mobile-updater or equivalent and try that bootloader (danger warning). That is IF one exists. Lg goofed on the ally and left fastboot enabled in their 1st version of firmware for it and fixed it in later shipped releases. We had to downgrade to v06 firmware to get fastboot. The command if enabled in bootloader is adb reboot bootloader to get to it. If its disabled it will just reboot as normal.

Here are instructions (for ally DO NOT FLASH THIS FIRMWARE -reference only)and link to tool to LG tool to downgrade frimware. http://androidforums.com/ally-all-things-root/166588-how-flash-stock-lg-rom.html

one question why do we need fast boot ?

Fastboot is protocol used to update the flash filesystem in Android devices from a host over USB. It allows flashing of unsigned partition images. It is disabled in the production G1 devices since USB support is disabled in the bootloader[1]. This can be changed if you get root on the device.

So, seems that it is for flashing of firmware. I thing that fastboot is something like recovery with some more?

On the Ally one could re-enable fastboot by flashing an old firmware. But afaik the GT540 had the support for fastboot enabled thanks to some russian guys who rebuilt the bootloader without having access to a pre-release rom. I wish they could to the same for the P500. I would ask them myself on 4pda.ru, but unfortunately I can't speak russian.

It's way better than recovery. Believe me, Google would not have created it if it weren't that useful. Try booting a custom kernel on-the-fly with your recovery.

Great, and what we are waiting for?

I see there has been no progress so far...

I have Fastboot! Mostly...

I have something on the Fastboot front. This being my first time hacking around with android stuff and not WinMo (screw winmo... bleh), I maybe need some help for the next step.

First off let me say that the winding way I got here includes stuff highly derivative off work from http://forum.androidcentral.com/lg-optimus-s-roms-hacks/45401-rom-thunderom-v1-5-12-14-2010-a.html this ROM for the optimus S. I want to ask their permission before I post steps on how I got here.

Here is where I am at.

On my phone:
Fastboot mode started
udc_start()
-- suspend --
-- reset --
-- portchange --
-- reset --
-- portchange --
fastboot: processing commands

YAY

Then windows installs for me a FastBoot Interface (Google USB ID) [Yes.. I was in Windows at the time lol]

DOUBLE YAY

This seems to work...

I can fastboot reboot, fastboot reboot-recovery, and I can wipe and assuming flash stuff (not trying just yet) with fastboot.

Only issues seems to be when I 'fastboot devices' I receive:

? fastboot

AND

I have to reflash or Nandroid restore to a more stable ROM to NOT go into fastboot mode.


From the sources I am reading, it should be more specific with my device ID correct?

Thanks for any ideas/help or whatever...

 

[The_ERROR]

Thanks for your trying! ;-) I look forward for fastboot!

Unfortunately I can't help you with this problem.

 

[jtaylor63]

Nobody here can speak russian? Asking on 4pda.ru how exactly they managed to enable fastboot on the GT540 might be helpful...

Some (possibily useful) info here

Thanks for the link, grabbing some .kdz from there. It might take a bit though... their filehosts are slow >.<
