  1. Hi
    I tried to flash the 2.1.2 OTA using full 2.1.1 ROM and the OTA zip file. I was on 2.1.1 and root.
    But after flashing the two zip files and SuperSU I saw that the version was still 2.1.1 in About phone.
    Then (not knowing how things work very well) I flashed 2.1.1 full ROM and updated OTA normally. The update happened through TWRP.
    After that I don’t have TWRP anymore. Stock recovery only.

    When I tried to reflash TWRP with fastboot by phone is not being detected as fastboot device. I’ve no idea why this is happening. All my adb drivers and fastboot drivers are the same as they were the first time when I rooted my phone.

    Can you help?
