Can you check your current build number?
I had to update to ERE27 before going to FRF50. I just got my phone last week but it shipped with ERD79.
does anyone still have the file go frf50. If so please send it to me. I will give you my info through a pm. Thanks
If I had to name my greatest strength, I guess it would be my humility. Greatest weakness, it's possible that I'm a little too awesome.
appleslayer and shane and maris, finally i updated to 2.2 frf72, thanks the help.
before i only add a .update before .zip, maris tell me rename to updat.zip
i change the "whole name" to " update.zip " it work fine...
ERE27 Build here ROOTED otherwise stock..... and stock recovery.
It starts to load and gets to "verifying current system", then I get some long failure ending with (system 7) and it aborts the install. Can't figure it out. I've tried everything here people. The file I'm using is a FRF50 from ERE27 so I know that's correct though I've tried a bunch.
Another interesting thing, when I hit the bootloader from the 3 skateboarder screen I get a quick list of errors about no image file>passing etc. etc. etc. its like 5 lines then it very quickly clears. Is this the cause of my problem perhaps?
Thanks to anyone who can help at all.
^ Edit.... am I even rooted? I have the torch program and I've had it for some time. I also have tethering aps that work like Barnacle. I am 99% sure I'm rooted, how to be sure?
Reason I ask is on the link below the instructions for non-rooted fit properly and the instructions for rooted don't because I have to hit the up volume + power to get past the triangle warning sign into my recovery. The final screen for update.zip is blue, not green like some people seem to have....or maybe thats cause they're already on 2.2
