Hello I tried several recent roms gingerbread or ics and in every time I do not have data connection but all the rest works very well.please help.
It is very unlikely.
What ROM did you try? SD version or NAND? You mean no data connection in 3G or wifi? You can try some clean and simple ROM, ex. NexusHD2-gingerbread, or Tyween's Typhoon CM7.
I have install typhoon , nexushd2 , mwakious , haldric , always in nand with ext4 1024mo.I have no 3g or internet connection (data transfer) , possible problem apn or i don't know. my clean install : task 29 magldr 1.13 , recovery 220mo, partition sd and install rom version magldr.
I have the same problem!
Wifi is on the other hand working flawless!
someone have the response?
Restart 3G
I posted this in a similar thread. It worked for me when I lost 3G. You may also need to check and update your APN settings for your mobile network if the below does not work. Sometimes removing the sim resets it.
# Go to Wireless & networks # mobile networks # network operators # Search networks # scanning for networks # list of operators will show up # select your network# Then go to Airplane mode # tick the checkbox to on for few seconds, untick the checkbox, phone will go into short reboots, re-enters your sim password to start your phone to your mobile network.
maybe you can check your APN setting for your networks,,,???
Hi,
I have Lenovo A820e which is CDMA + GSM phone.
I am unable to switch on data either on CDMA or on GSM. However, the phone is able to use wifi.
I have saved the new APNs for Relaince CDMA and Idea GSM. But to me, it seems that China Telecom is preventing data connection other than its own.
How can I solve this problem ?
Plz. help.
A820e
Hi, I have also an A820e. Got to the same point. I've installed a ROM with GApps and got everything working except I can't get 3G data, only GPRS.
I think it's ROM related.
Have you been able to find a solution?
It seems that Lenovo A820e doesn't have the 2100 band which is required for 3G communication in Europe.
The way I was able to activate data in the ROM that has the google services is by introducing the following code in the dialer:
*#*#4763#*#*
After this a message telling me that the data has been started appeared and I was able to control.
Also before this I made a change in system/build.prop
to default the network to gsm. I've added:
ro.telephony.default_network=1
(Should be rooted to have access to this. I've used Root Browser)
Hope this helps.

Click to expand...
Click to collapse
*#*#4763#*#* - did not work for me... It seems it depends on ROM
thank

Which ROM are you using ? Can you give me the link ?
Hello! I had the problem that the only settings to prefer LTE was CDMA + LTE/EvDo on my Huawei Y6 L-21.
Everytime i chose it, my provider connection was lost and the IMEI deleted. Only after flashing the stock ROM i got my IMEI (and the connection) back. I searched on the internet and found this little workaround / fix:
Using the Dialer USSD code Exploit
This is another easy method for setting 3G/4G only mode on Android devices. It is as easy as dialing some set of USSD codes on your phone dialer.
To force LTE/TDSCDMA/WCDMA only mode on android devices via the USSD code exploit, you’ll need complete the following steps.
Step1: Dial *#*#4636#*#*, on your phone dialer and follow after the pop-up window’s options.
Step2: Click on Phone information1 ==> set preferred network type to complete the LTE/TDSCDMA/WCDMA only mode settings.
Thats it!

PS: I wanted to create this thread in the development forum, but i haven't enough posts.
Is there a way to mod my phone that it only connects to my carrier?
I got an issue with an custom rom. It is the best rom i tryed so far. The problem is, that it connects to the neighbourcountrys carryer and dont let me change it.
Can i change something so that it only connects to my carryer?
EDIT:
I solved it myself
1. Dial *#*#4636#*#*
2. Phoneinfo
3. Networktype = LTE/UMTS auto (PRL)
4. ???
5. Profit

If you are facing problems of poor natwork whatever network on are u there is something for you to get Best network coverage
There are money tips n tricks are making round all over the internet
I'm also the one of them who has searched n searched on google about jio network
Than i found artical about network band
Band 3(1800)
Band 5(850)
Band 40(2300)
All above all are Lte band is jio provide to us
In my case I'll always get band 40 it's slowest band in my area why beacuse a phone automatically switches between band according to the strength of the signal in different locations
So 1thing i know that i have to control my network band or lock band 40
Than i searched and searched on google
I have read lot of article about changing your band easily
Read about different code for different mobile
For example *#*#4636#*#* or phone info to select network mode lte only nothing change same result
Than shortcut master to creat "service menu" or "Engineering mode" still no luck with different 2 device
Than *#001# it's work but can't change or lock anything
Than i finally found on Xda a magical code *#2263#
this is really magical code for Samsung devices
If it is work for you than you don't need any apps or U don't need to root your phone
Stil no luck
It doesn't work on my phone
Than searched about how to make this code to work i found small artical on xda and it's work
But you need root to access system file this guide is not work for non-rooted samsung phone
i have just tested on my s7 cutome rom of kill-switch black diomaond v7
So u need esfile explore
To perform this action
In Esfile explore goto
System/csc/etc Or System/omc/INS itc
Now look for the file name with
INS_keystrings.dat and rename it to something like xyz.keystrings.dat
Now go back to System/omc/XXV/etc and copy the xxv_keystrings.dat and paste the same where u have change file name
Omc/ins/etc and rename it INS_keystrings.dat now reboot phone
And U will see *#2263# code will stated to run
Now u can chhose any band you want or lock any band which u don't want
Note:-- what if you dont have xxv or sin csc than you look for xxv or sin csc and flash it
I think it will work without above trick but it doesn't than do it manually
