different country(UK) ROM ..i am not sure that whether it's workable on Malaysia ROM or not

Phew, completed!

Now pain in the butt moment, downloading back all the stuff

0024 to 2009 (amber)

I slowpoke liao, just online after raya.

Just straight upgrade.

Yep, as stated by fellow forumer here

You be like receiving a brand new phone

Better backup all the data first.

Since this phone  don't had external storage device (SD card), all files (contact, sms, music, video, apps) will be formatted when flashing new ROM, please do necessary backup before proceeding.

YOU HAD BEEN WARNED. 

You can always use the phone as brick or something. Nokia is quite durable.

Wohoo!! successfully flashed to GDR2 + Amber! Thanks to all sifus here 

GDR2 = General Distribution Release 2

Threat it as some kind of Service Pack release by Microsoft to improve Windows Phone 8 OS.

After GDR2 roll out, microsoft will pass to phone manufacturer (Nokia, Samsung, HTC, Huawei) to release at their own discrete (May need to test hardware compatibility, or bundle with their own upgrade).

Since GDR2 had released, Nokia also prepared their phone's firmware upgrade (codename: Amber) to bundle with GDR2 and release to public.

Currently the release is not official yet, all the member here flash the ROM on their 920 is a leaked ROM file from Nokia server.

Either you flash the leaked ROM file or wait official update available, both also contain both GDR2 + Amber update.
