Hi guys, thanks for the replies
Personally, I would leave phone part alone unless you have an exact copy of your phone firmware IJ2.
I flashed JJ1 to my I8000L phone and it works, but I think it may be responsible for not picking up signal in some places where they are only using 850 band and 1900 band is not available. Unfortunately there is no way to go back to original phone firmware except by Samsung service center...
Nice, well.. despite the fact that there might be some errors, it is good to know that it will work on the I8000L too!
I've used PDA/CSC dump programs to backup PDA and CSC parts but I don't know how to backup the PHONE part, is it possible?
Also, is it possible to backup the whole thing? (EBOOT)
I see, you mean, if I update from I8000LUTIJ2 to I8000XXJJ1, I won't be able to go back to I8000LUTIJ2
But I'll still be able to update to anything newer than JJ1 right?
The reason why I want to update is because right now I am running Android Froyo Beta on my Omnia II
But my battery lasts only 3-4 hours, wich is less than ideal for daily use..
I did some research and noticed that some PHONE part versions affect the battery life on Android drastically, so I am planning to make an update
I updated my phone a lot of time, with mod roms and VIVO and TIM rom, any problems... Upgrade and drowngrade, now my phone version is JJ1 6.5.
The only problems is bluetooth MAC... FF FF FF.....
The only problems i found in 3g is the APN!
Luiz, did you updated all parts (PDA/CSC/PHONE) to JJ1? Or only PDA/CSC?
I've tryied some different ROMS but never updated the PHONE part..
Thanks again guys
I really appreciate your help
