Anyone tried this yet? Bought the phone in China a few days ago and really want an EU or global firmware.

So I followed all the steps and everything seemed to work fine. The TWRP software said it was going to reboot into recovery but it is stuck at the android logo screen. When I hold power button + up key its the same, stuck at the android screen. When I hold power button + down key it boots into...

Thanks, I'll give this a go when the handset arrives in a few days and report back. Can you explain how to then install the Vanilla 4.4.2 Android firmware? (or any other suitable stock firmware for the device)

Do you know if this will also work on the UK model?

I don't remember reading this and I have been following the thread. Can you point me to the right post please? Many thanks.

There is another new firmware available as of yesterday (B10). Get it from http://www.ztedevice.com/ - select Hong Kong as the country.

Thats great. I'll take a look later today. Might flash a generic firmware to get rid of the o2 Branding.

The model number of the phone (RM-846) isn't showing up on Nokia Care Suite. I guess firmware isn't available yet then!

I currently have a Lumia 710 (Orange UK) which I use with Virgin UK. However, I have just made the plunge to buy a Lumia 620 which comes locked on o2 UK. Is there a way to unlock the Lumia 620 like there is the 710/800? i.e. flash a bootloader and install a custom ROM? or should I resort to...

I have tried this but when the phone goes to flash it hangs for a second and then says the phone is in the wrong mode :eek:

Mine doesn't show a drive either :( really don't want to have to change phones. Any idea how I can update the device? I used to be able to use cabs but I am now getting an error when I try to update that way - so I need to install a rom from scratch.

Also having trouble with this, did you work out how to do it?

hasn't worked for me, still shows up as drivers not installed in Device Manager. When I point towards the files it doesn't accept them or if I do a computer/internet search. Just says driver cannot be found. Any ideas? ---------- Post added at 10:07 PM ---------- Previous post was at 10:03 PM...

Chynkinese, did you work out how to flash a rom with the NCS or any other software? I am also getting the 80180048 error and have a Qualcomm bootloader. I am stuck on firmware 8107.

Still getting the same error: I have tried flashing with NCS but windows cannot find a Qualcomm Driver? Any other ideas of how I can get the update?

thank you but its already installed :( Maybe its because I am trying to do this in XP. I will try on my Windows7 machine early next week and see if that makes a difference.

I am trying to follow the guide http://forum.xda-developers.com/showthread.php?t=1737907 to upgrade to tango. however when I try to install the first package, I get the error "80180048, error message: UI (image update) installation failed due to an error." I have tried a hard reset which has...

i'm also getting the 80180048 error.

I got mine unlocked direct through T-Mobile/Nokia. Working now on Three. Might be worth contacting the network its locked to.

fonefun, thanks for the update on the carrier situation. Does this mean that the database is only accessable by T-Mobile and Orange at the minute or do unlocking sites have access to the algorithm/codes too?
