The alternative is, save a copy of the stock recovery image on your computer:Guys ,
Currently I m on Os 3.2.1 rooted with xposed ..
I received the ota for 3.2.6 of about 230 mb ...
Should I download and upgrade it directly, and will I get root access and xposed working..?
1. reflash stock recovery back onto your phone
2. Install the downloaded OTA update, you'll lose root
3. Reflash TWRP recovery, boot into recovery
4. reflash the supersu.zip that's still on your phone, this does not get erased
5. Reboot, then go back into TWRP
6. reflash the Xposed installer zip thats still in your phone, this is not erased either
Even if you download the full OTA zip you'll have to do steps 4-6 anyway. I've chosen to do this than keep TWRP the whole time, whatever is more convenient to you.
