right to save confusion this is what i did
1) i downloaded that file and renamed it update.zip then copied it to the root of the phones SDcard
2)turned phone off
3)held both volume keys and power
4)selected motorola recovery
5) got android symbol pressed volume keys again to get menu
6) selected update from sdcard select update.zip
7) once phone updated select restart phone
8) delete update.zip from sdcard
9) copy the ics file to Root of sdcard renamed it update.zip
10) do steps 2-7 again
11) have ICS
This apears to ONLY work on GSM NOT CSMA and seams to only work if you have EU retail version
any futher questions just ask and i will try and help you
at no point do you need to plug into pc other than to transfer the zips to the sdcard
did everything just like in the instructions, installed the first update without a problem but when it came to installing the ics it keeps giving me the same error as before "status 7" or whatever. Any ideas? i have a gsm razr bought in uk
