At some point or the other, your Android
phone (and you) will have to leave the network reception stronghold and venture
into an area of not so encouraging signal reception. In my previous guide
on boosting the Internet connection speed on your Mediatek Android phone, I
explained a life-saving technique that tells your MTK phone;
3G or 4G = Give me, EDGE or 2G = Keep it
In today’s tutorial,
we shall be putting yet another device issue behind us, the problem of no
service or reception when network mode is switched to WDCMA (3G) only.
Could you shed more light on this particular
issue?
This problem borders around you being in
an area with 3G coverage and having signal when your phone is set to 3G / 2G.
The problem here is that when you set the phone to 3G / 2G, you get the slow 2G
reception most of the time and switching to 3G only gives you no reception.
There are 2 methods:
1.
Settings Menu:
Navigate to Settings > More > Mobile Networks > Select your Service
Provider > Preferred Network type
2.
Engineering Mode:
Install MTK Engineering Mode >
Launch the app > Select MTK Settings > Tap Network Selecting (Under the
Telephony tab)
Ideally, downloading the firmware and flashing it (especially secro.img) using SP flash tool
ought to fix the issue. If this doesn’t
resolve it then:
·
You’ll need to get a working phone of the same model which is not
having the issue
·
Flash TWRP recovery to both phones (Use SP flash tool if not
rooted and Rashr.apk if rooted)
·
Boot the working phone into TWRP recovery and
backup the system, secro and nvram partitions
·
Move the TWRP (backup) folder from the internal storage of the
working phone to that of the phone having the 3G issue
·
Boot the affected phone into TWRP recovery
·
Restore the backup and reboot the phone
Note: This fix also works for the WiFi NVRAM
WARNING Err = 0x10 and the NVRAM WARNING Err = 0x02 errors
