Hi folks,

I didn't use my GT1 A912 for a while.

I'm still on Android 6 (firmware GT1-113MO).
Is this the last update? Can I update directly to 707NO?

Thanks for your help!

[solved]
After firmware upgrade my GT1 2/32Gb with s/n started with A912 (from 113M0 to 707NO) I have problems with audio playback on bluetooth headphones Bluedio T2 - stuttering or something. On old 113 stock firmware there was no such issues.

info update: After teardown I found, the board inside is model S912 2/32gb with chip LTM8830, but s/n label was A912.
So, the problem was in a choice of wrong firmware for AP6255 instead of QCA9377 (8830).

After reflashing a proper firmware 707N0 for QCA9377 the problem with bluetooth audio was solved.

Yes, you can upgrade from 113 to 707 by using USB cable. But you will lose all information and software settings due memory reformatting. So I suggest you to use a backup like Titanium Backup prior to firmware upgrade.

But I can't install Netflix from the playstore. I have to download the APK.
Is it normal?

Are problems with 3D games and other Kodi issues fixed in this new release? I am still on 6.0.1 and looking forward to update to new firmware.
Thank you.
