Are you sure for the OTA ?
What do you mean?
OTA won't change (more or less) the language, which was set before!? Yes! I tried...
Download this file:
Rename it update.zip. Copy to root of your mobile. Start system update with update by disc. You will have 1.41 with all of your old settings, programs, etc.
Do not forget to unroot before!
I am trying to update with your indications and I am getting the following messages inside the recovery:
Finding update package...
Opening update package...
Verifying update package...
E: footer is wrong
E: signature verification failed
What could be causing this?
update to 1.38 by OTA
I am not being able to update to 1.38. OTA downloads the package properly when rebooting the installation fails (when rebooting says something about the files not in correct place or something like that. I have no time to read it )
