[Samsung Galaxy Xcover 2 Questions & Answers] TorqueR11:
Hi peoples!

I’ve recently installed Cyanogenmod on my Samsung galaxy Xcover 2 (GT-S7710). But when I was done installing my phone couldn’t get any data (H/2G/3G) or call and receive calls. Could someone tell me what I did wrong or forgot whilst or after I installed Cyanogenmod? I would like to know because I’ve read other threads where people with a GT-S7710 do have a working network service on their phone with CM. And I also would like to know the solution to this problem because I can’t take a beating :p.

I apologize for the length of this first post ;). I just want to be totally complete about what I’ve done and tried so far to get CM to work with network service. I posted all this information to inform you all and so you could stripe a lot of questions off your list for finding the solution. Also I think this thread may be very useful for other Samsung Android users as well.

Kind regards,

The problem

So the problem is that when I’ve installed CM10.1 or 10.2 or 11 to my GT-S7710, I don’t have any network service anymore. I tried to install CM using the following method: http://blog.arinium.fi/2014/07/howto-fix-samsung-xcover-2-issues-old-android-low-memory-slow-ui/. I installed CWM 6.0.4.6, wiped cache and installed CM10.2. After this it got stuck in a bootloop. Using the advice of this page: http://xdaforums.com/showthread.php?t=2084905 which was to also wipe data/factory reset and wipe dalvik using CWM it worked!! YES!! But **** no service.

Used Files to install

Links I used to download CWM, CM and Gapps come from these pages:

CWM: http://www.adriadata.net/xda/skomer/

CM: http://www.adriadata.net/xda/skomer/

Gapps: https://itvends.com/gapps/

What I’ve done and tried

I tried to get network service back when I installed CM10.1 and CM11. In both cases I did a full wipe of data/factory reset, cache and dalvik then installed the latest stock rom/firmware 4.1.2 and do the instructions over again form the chosen method. I did notice that my phone does have network service when I have installed the stock rom/firmware downloaded from this link: http://www.mrcrab.net/down-firmware/14362/Samsung-Galaxy-Xcover-2-GT--S7710.html, My device also has got service when CWM 6.0.4.6. is flashed over the stock rom/firmware. Just not when I installed CM. CM10.1 was running more smoothly than CM10.2 and CM11 was running a little less smooth than CM10.2.

Attempt to solve the problem

I’ve brainstormed the following pages to get to the point of giving up :p.

The most pages are threads for other devices, but I thought I just read it anyway, maybe I could get some useful information out of it. Some pages talk about CDMA/RUIM that you can find under network setting in settings, but I’ve not been able to find it on my GT-S7710. Other data found in these pages are also not corresponding with my device.

What I did notice and learned was that information in the EFS folder like Imei, Baseband etc. are used to find and recognize the simcard and thus enable data usage and be able to call and receive calls. So I thought why not backup a copy the EFS folder and place it in CM’s EFS folder after install, so I did. I installed stock firmware where my network service works following the same steps I took that I described earlier, backup the EFS folder to sdcard1, install CWM and CM10.1 and tried to copy the backed-up EFS folder to CM root. But no way would it replace the CM EFS folder, CM simply blocks the copied EFS folder from stock rom/firmware.

I am just out of ideas now and am requesting your aid. Please help me :(.
