GW820 Custom Rom
For those who don't fear to brick their phone, you can try this custom rom (v11)
I've just made
As of now, nothing special with it, I just added Pim Backup, only to test the kitchen, so really no reason to flash it except to confirm whether it works or not. If you want to test it, use the stock rom in this thread
(thanks Dark9781) to extract the files into programsdata\LGMOBILEAX folder and then replace phone\GW820-V10d-OCT-27-2009+0.dz with mine (giving it the same name).
Once again, I can't insist enough on the fact that this is experimental
for now (for this test rom, I did some rebuild stuff manually, I don't know if it works). Once the tools are proved to be stable, I'll release a updated kitchen for you to play (it might take a week or so to finalize the tools, maybe less).
Unlock your GS3 with GalaxSim Unlock (compatible with any currently available rom, Jb included)
