Long story short, my brother was scamed to buy Galaxy S4. Now I'm trying to install custom rom on it because the current rom has 50mb of RAM free... I tried with many recoveries, but non was successfull.
Hardware specification of the fake S4 is :
(according to antutu)
Brand : ALPS
OS: Android 4.4.4
CPU Model MT 6589 (quad @ 1Ghz)
GPU: Mali - 400 MP
RAM: 512 MB
System storage is 120MB (if I can read corectly )
On this current rom GPS is not working (tried somo of Uncle MTK fixes but non worked, I think it's a bad rom)
Many, many thx!
I managed to root it with framaroot app.
