Re: How to update any L920 to GDR2/Amber in 13 easy steps!

Hi guys! My 920 is from at&t and it's unlocked by code (currently in Claro-Guatemala) if i flash my phone with these files my phone will still remain unlocked?

Yes, it will remain SIM-unlocked, so you can still use it on Claro in Guatemala. See this post:

I had to turn off data connection to sign into twitter on any app(not sure what that was about) But overall I'm very happy with this ROM and don't mind the tweaking to get things to work. The benefit for us tho is that we don't have to worry about the whole tethering thing. I wasn't able to tether before the flash so I lost nothing.

C:\ProgramData is a hidden folder. You need to enable viewing hidden folders.
Open C drive in explorer. Go to View->Options->View tab->Check "Show hidden files, folders, and drives" and press Ok or Apply.

Its probably been answered but Id like it if you could talk me through it. There was also a guy that said bing vision didnt work, is this true?

You have to delete "B1E09708_" You also have to delete all those in your RM-821 file.
