[Q] Branded Vodafone UK upgrade to .136
Sorry if this may have been answered before but...
I upgraded my software OTA from .257 to .290 and after various resets/repairs and reloading the.290 upgrade (via PC companion), I still had Bluetooth problems with my car audio and the hands-free system, which I rectified by using flashtool and "downgrading" my software back to .257 using this ftf -
C6903 14.1.G.2.257 Vodafone UK 1276-0815_R9A
Now that the .136 version is available, my phone still prompts for an "upgrade" to .290 and also informs me of this upgrade on the Sony PC companion.
Do I need to upgrade to .290 then to .136 OR
Can I use one of these ftf files to flash my phone using Flashtool -
C6903 14.2.A.1.136 Generic RU 1276-7743
C6903 14.2.A.1.136 Generic DE 1277-0154_R2B
C6903 14.2.A.1.136 Generic IT 1276-0557_R2B
C6903 14.2.A.1.136 Generic AU 1277-0078_R2B
C6903 14.2.A.1.136 Generic FR 1276-5833
C6903 14.2.A.1.136 Generic BAL
If so, which would be the best ftf to use and would I lose any Vodafone settings etc on my phone?
Any help will be appreciated!
Sony Xperia Z1 on Vodafone - downgraded to 4.2.2 because the Bluetooth stack on 4.3 is useless!
