I've bought a phone tha is a poor S4 clone.
MTK Root and Tools recognized it like this:
Hardware : MT6575 (MT6517 is Fake!)
Model : GT-I9505
Build number : Android ICS
Build date UTC : 20130725-095723
Android v : 4.1.1
Baseband v: MAUI.11AMD.W11.50.SP.V31.P2, 2013/05/09 17:21
Kernel v : 3.4.0 (wanglei@wanglei-desktop) (gcc version 4.4.3 (GCC) ) #1 Thu Jul 25 17:51:08 CST 2013
Uboot build v : MAIN2.2.ubt.3327
LCD Driver IC : 1-ili9806_6575_dsi
The thing is: The UMTS (3g) network don't work. It only connects through Edge network.
I've tried to restore IMEI - nothing happens...
I've used the MobileUncle tools to see the bandmode, but it shows only the 2g network (the umts mode is grey, and I can't set it up...)
My first theory was that the firmware doesn't support the 3g network, but, since I couldn't find a best firmware, that theory was... stuck.
My second theory was that this SoC (MTK6575) doesn't have 3g access but after some research i saw a lot of people tha have the same SoC and connects to this network, so...
Well, this is my story... someone can help me? Thanks in advance...
