I've got a question about ADB. I can't get my Y300 recognized in ADB, on my Windows 8.1 computer.
I downloaded the latest platform tools (rev. 19, ADB version 1.0.31) and enabled USB debugging. I also installed the Huawei Handset WinDriver, but when I enable USB debugging, I see that there are no compatible drivers for "Ascend Y300". Do I need to install additional drivers?
When I'm using Ubuntu, I'm able to use ADB and fastboot without a problem.
It's called "screen timeout" and has a 5 minute max on my phone (Lewa Recovery), so I think you didn't flashed Lewa Recovery, but TWRP 2.6.
I don't think that TWRP 2.6 has a bug with the screen timeout, so you can probably forget what I said about the screen timeout.
p.s. If you've flashed Lewa recovery instead of TWRP 2.6, you might want to go to "Settings -> Screen" and disable the screen time-out. Otherwise your screen will turn black after a while and you have to reboot your phone.
