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 .
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,
Rick Willems
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://forum.xda-developers.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:
http://forum.xda-developers.com/showthread.php?t=2384015&highlight=no+network, http://forum.xda-developers.com/showthread.php?p=43294839#post43294839,
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 .

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 .
Got the same problem here,unfortunately no fix yet
Try this:

For those trying to install this or another rom and having the no signal(no smallband) problem. This worked for me on 2 xcovers.
Install cmw: http://theunlockr.com/2014/02/27/install-clockworkmod-recovery-samsung-galaxy-xcover-2-gt-s7710/
Root it: http://theunlockr.com/2014/02/27/root-samsung-galaxy-xcover-2-gt-s7710/
Now normally you can install the custom rom now(vanir). If you do you probably get no signal.
Start odin and flash this file : S7710XXAMB6_S7710OXEAMB3-20130713.tar.md5
I found it on this site: http://www.ulozto.cz/xHADj5PD/samsung-7z
If its dead you can pm me and I can send it.
After I flashed this the phone would just go in a bootloop.
Don't be afraid this is normal.
Now install the vanir rom in the cmw recover mode.
After this it should work fine.
Add a microsd card with 2 partitions and install mount2sd and you have a fully working phone with(almost) unlimited space.
I'm using if for an year now and it works great.
Better then most €500 phones which break after 1 fall .

With skomer it is definitely a baseband problem. Changing baseband solves the network signal.

because i have the same problem, i installed cm10.2 and everything were fine for a week and then no signal, i tried to install all the available firmwares out there, the closest i got was to find network and 3g i made a successfull call then i shut it off. At the next boot nothing again. My baseband is xxxx. What do i have to do to change baseband? My IMEI is correct.
does anyone have a /modemfs and /efs folder available to try or/and a modem file to flash?
Odin flash
Go to this page https://boycracked.com/2016/09/11/official-samsung-galaxy-xcover-2-gt-s7710-stock-rom/ and download stock rom labeled "oxeamb3". Put your phone on download mode and connect to odin. Flash this rom with it.
After that, flash your clockworkmod and custom rom. Vanir or CM.
If you still lose signal, try with AND2 stock rom. It's been a while since I did this so I don't remember exactly, but I think AND2 had problems with signal and AMB3 didn't.
when i connect my wifi,,it will connect then suddenly disconnect, connect then disconnect again. i had searched the thread but i dont find any solution. i tried changing my modem and bootloder but problem still exist
Try a clean install (full wipe) with the newest build (12/21/15), which uses clean LP libs.
Hello,
After many researches on google I can't find how to solve my issue with the buetooth on my samsung galaxy s4. I have installed the last CM 13.0 snapshot rom (13.0-20160820-SNAPSHOT-ZNH5YAO0J3-jfltexx). To proceed I started with a GS4 with the following ROM I9505XXUHOH2_I9505OXXHOI1_XEF downloaded on sammobile. I did a full wipe to install a new ROM and then I installed the CM ROM. The bluetooth was ok at the beginning (around 3 days after) and now the BT is OK. When I restart my phone it turns ON but after severals hours the bluetooth crashes (without any warning). If I try to put it ON again it turns OFF automatically after few seconds. The only solution is to restart the phone to recover it.
I tried the bluetooth during one day without any issue when the GPS is OFF maybe this can help
For information I have no issue with the samsung ROM.
You are my last chance
Thanks in advance for your help and sorry for my English
Try a different ROM or a different snapshot.
Another idea?
Hi. After trying a couple of custom roms, I wanted to go back to a stock rom via Odin. I actually succeeded. The phone boots, and android setup screen comes. But in the "wifi connection" screen, when I touch the button to turn the wifi on, it just refuses to turn on. It goes back to off position. I have tried several different country's stock roms (4.4.2 only, I haven't tried 5.0) and they all ended up the same. I just can not turn wifi on in stock rom. Wifi works in custom roms that I installed using TWRP.
Any idea why this happens?
By the way, I also tried flashing different modems, but the result is the same. I read that turning off the phone and removing the battery helps, however, in my case, it didn't.
Any help is greatly appreciated.
EDIT: As I have looked into the issue, some people claim that a custom kernel usually solves wifi problems. I haven't tried it yet but I will as soon as I can get my hands on the phone. Also in another post, I have seen a build.prop tweak "ro.securestorage.support=false" which is claimed to have solved the wifi issues. I am writing these to be of help to others that might encounter the same problem. I will update the post after trying these ideas.
EDIT 2: It turns out, when you flash a stock rom, Odin can't actually flash the modem partition. It seems like it does but it actually fails. You have to do it twice.
No Wifi
Hi,
have some trouble with my Galaxy S4 (GT-I9505). Since 2 weeks I'm trying to get wifi working. 2 weeks ago I decided to root the phone (everything complete stock Android 5.0.1). At this moment wifi was working well..
I did:
- Flash TWRP with Odin
- Flash magisk 18.1
--> booted phone..
Everything seemed to work well..expect wifi. It wouldn't turn on. When trying to activate the WiFi button by sliding to the right it stays grey and after 10 sec. the slider goes to the right side again.
What I've done:
Downloaded several stock firmwares from sammobile --> no wifi
Flashed serveral custome rom's (lineage 14.1, 15.1), android 5.0 and 4.4 based --> no wifi
Tried differnt kernels --> no wifi
Flashed different bootloaders and modems--> no wifi.
Tried to delete files in /wifi folder suggested here in forum --> no wifi
Tried to modify buil.prob set the security value to false suggested here in forum --> no wifi
I don't think thats a damage on the hardware. It must be a software issue?
Bluetooth and mobile data are working well. GPS and wifi seem to be broken.
After spedning weeks of flashinng, recovering etc.. I am frustrated and don't know what to do.
Any advices?
My wifi is not being enabled with this rom. Does anyone know how to solve?
I've recently decided to update my phone to 9.0 (it was out of date) and flash a custom rom, from a maker I'd used before. For reference, this is the custom rom; https://forum.xda-developers.com/ga...ce-development/teamexykings-lightrom-t3891294
I followed the instructions on this custom rom, and have tried using the stock kernel and the TGP kernels provided in Aroma when I've installed the phone. Annoyingly though, I always end up with my WiFi not being able to turn on. Mobile Data works just fine, as does Bluetooth.
I have found this option; https://forum.xda-developers.com/showpost.php?p=75667847&postcount=176 (from this thread: https://forum.xda-developers.com/ga...t/kernel-nox-kernel-v1-t3721469/page18post174) but when I've finished the install of the custom rom, there is no 'conn' folder in the directory; 'data/misc/conn'. Even with the creation of one, there's no change to the WiFi status and I'm unable to turn it on.
Is there something wrong with the Custom Rom? If anyone can help, please let me know, as I've yet to find a solution.
EDIT: Issue Fixed. Can be closed now.
