Lollipop TWRP + 6.13.402.2
I'm totally lost.
Can someone point me to some tutorial how to upgrade to Lollipop?
Currently I have HTC one (m7), dual sim , 6.13.402.2 with Android 4.4.3, HTC Sense 6.0, 6.13.402.2 with custom recovery openrecovery-twrp-188.8.131.52-m7cdug.
I'm lost..... should I flash to stock recovery and update via OTA update ? (I can't find the stock recovery for 6.13.402.2 ).
Or should I directly install RUU?(I can't find the RUU for my model -6.13.402.2 )
Please, please help.
Thank you Petr
