Goodevening, you propably have upgraded to 2.1 version, not 2.2, since 2.2 is not even out yet for GT540 atleast officialy :)
Problem is you cant downgrade to 1.6ROM now. And as far as i know theres no Arabic Languages 2.1 ROM out yet (Correct me if im wrong someone)
Your option would be to download "MoreLocale 2" From the Martket. It only will change half of the interface to Arabic tho, but its better then nothing :)

That ones kind of sketchy for me, theres an option in MoreLocale2 [free in the Market] where you can set a custom locale. Press the button directly above the call button, select custom locale and try "ISO-8859-6" for a VERY basic Arabic character set.

A gazillion thanks to ilovelg (and to anyone else who provided the information), the emergency download instructions saved my bacon.

Thank you very, very much. :)

Hi everyone,

i am looking for a complete arabic interface - you know, as if you were an arab with arabic as your only language and went to a shop in egypt or saudia and bought a phone, i'm sure we agree it would be in arabic right?!

anyway, it's not for me but for my friend that i gave a orange san francisco (aka ZTE blade). he's an arab with a tiny amount of english so needs it in arabic.

tried more locale 2 but it doesn't seem to work.

any other ideas

this phone has android 2.1

am i right in thinking that any android 2.1 rom would work, you know like, windows 7 works on a dell, sony or acer?

if that is true then an arabic 2.1 rom would be perfect, no?

it has the clockwork recovery mod installed and is rooted (i think - i am a newb)


thanks for your time

deemboy = newb squared

i followed the step by step instruction but at the end of the day - i never encountered such error but to my surprise my lg optimus gt540 is still on 1.6?

i'll give it another try and see what happens.



God bless us all!

Thanks, worked great.

The official tools didnt work for me, stopped at 64%, gave me some bogus instructions on how to start again and pretty much bricked the phone.

This worked first go, although you forgot to mention to install the MSXML parser included with the KDZ_FW_UPD tools :)

Cheers!
