Hello!
After buying this phone model, I was horrified to learn, that he does not want to connect to my wi-fi router in the 5 GHz range.
Full description of the problem and how to resolve it are described in this and this topics.
I have carefully read both topics and the following materials:
MccTable.java
Mobile country code
Dalvik opcodes
I tried all the proposed solutions and they are not quite like me. I decided to do everything a little bit differently.
telephony-common\smali\com\android\internal\telephony\MccTable.smali
OLD
NEW
framework\smali\android\net\wifi\WifiStateMachine.smali
OLD
NEW
Result - archive for installation through TWRP:
- for 3G model (K2_U)
- for LTE model (K2_UL). If not work, try this
Try, check, write the results.
Enjoy!
