[Q] Bad wifi detection + reinstall stock rom? - Galaxy S 4 Q&A, Help & Troubleshooting

Good day,
I joined a ship and now I am sailing for 5 months here. The problem is that we have wifi internet on board and my s4 has detection only 2-3 meters away from routers. All other devices around are working, smartphones and notebooks. Anybody knows a workaround? I went to service 2 times until now for different problems, but now I cannot go anymore for the next 5 months.
Now I have Omega rom but I want to try to reinstall stock rom via odin. My question is: If I clean format from philz restore to install new rom, it will delete everything on the phone, then with a nandroid backup from recovery and copied everything from data/media/0 can I restore it as it was before.
Note that my internet connection is very bad, worse than dial-up.
Thank you in advance!

Problems with 3g and ROMs

So when I first rooted my phone I put Fresh on there. I installed the ROM and the 2 radio files. I then got the 3d and gave the evo to my gf, but fresh was very slow for me so I installed the CM7 ROM.
CM7 was very buggy for her, especially since she was new to Android I decided Sprint Lover's ROM on there and flashed a newer update on it since.
The problem is that she has been having problems with 3g. She has so many problems and errors with 3g data. It shows that she has 3g, but she gets errors when she tries to access the internet.
My question is, how can I get it back to stock or a nice rooted stock rom to try and fix this problem? Do I just flash a stock rom? I'm guessing the fresh radio's might be messing something up. If there is a simple solution to this without having to do a full erase I'm sure she prefers that, being that we've fully erased her phone like 4 times already, lol.
Thanks guys.
Get the Sprint Lovers all-in-one package from here: http://forum.xda-developers.com/showthread.php?t=830153
It's flashed through hboot (it's a PC36IMG.zip) and will flash not just the rom but also the radios. This will wipe everything.
Alternately you can go here http://forum.xda-developers.com/showthread.php?t=715485 and get just the latest radios and flash those. Flashing this will not wipe everything.
If the problem is with the radios then that should fix it. If it doesn't, then it's likely that the issue lies somewhere else.
thanks, just installed the new radio's. Will see how it works.
I would definitely just get the app mybackup root and back everything up apps/data , sms etc.. Then just restore everything after you flash a new ROM.
Then just do a fresh install of what ever ROM you want then test out different radios till you find the best ones that work for you I'm on old radios because the newer ones didn't work great for me not all evos work the same .
I hope that helps you out some.

I got simalar problem like u.
I installed new radios, try different roms like MIUI, CM6, CM7, Miks, Minn, OMJ's, etc...... finally I go back to stock rom but still got the same problem.
I almost crazyy
the phone never got 3G signal, it only works 1G no matter what I did.
I've reserched couple days but looks like nobody got my problem.
now I fixed my problem btw... well I'm not sure this thing works to u or not
anyway try it if u still got 3G problem.
*I don't even remember where this posted originally,,, somewhere this forum or not,,
huge thanks to original author btw
download 'MSL reader' at market n get the numbers. it's 6 digits.
go to your phone and type ##3282#
tap 'edit mode'
type that 6 digits from MSL reader
tap 'data profile'
open menu n tap 'restore'
then the phone will be reboot.
when booting is done, your phone will start resistering to network.
after that, if something popup n ask update (mayb PRL update), 'cancel' it.
mine works perfectly now.
hope this work to u.
ok thanks, i'll try it out. I do get "3g" at the top though, but always get an error while trying to retrieve data.
Also, what files in the SD card are necessary? Is there a list? I think there are so many junk files in there taking up space, I don't know whats necessary and whats not.
Please help slow EVO 4G after flashing Sprint Lovers All In One
Obvious Noob here.
having issues with my Evo 4G after flashing Sprint Lovers All in one
phone seemed very fast immediatly after flashing SL but since then has become just overall slow.
in fact, i'm downloading an update to ROM Manager right now (a 2.27MB file) and it's taken literally 20 minutes to get to 75%. it's painful!
when i go in to manage applications...says "computing" on space, data and cache etc.
before i flashed SL all in one i ran factory reset 3x in a row prior to flashing - i did NOT re-format my SD card but had it removed (after unmounting).
Should i try to wipe and re-flash or just go to CM7? Are there any things i can try before re-flashing or moving to another rom? Please help..
thank you OB1B

Real Problem after Updating to the latest nightly

Hello together,
after ive updated yesterday to the nightly 204 ive got a serious problem.
Every time i use the mobile data connection....the phone is rebooting.
The really wired thing is that after ive restored my backup which was totally stable, the problem is still there. Even when i try my really old recovery of the stock sense...the phone is rebooting something like 20 seconds after using
a mobile data connection (which is working in that amount of time)
I have really no idead what to do now.....any help is welcome.
Thx in advance!
Try reflashing the radio. (All 3 versions, if one of them doesn't solve the issue) I believe pyroblazer was having a similar issue on the RemPuzzleROM and a radio reflash fixed it.
at first i want to thank 3xeno for his quick help (as he always does). Really thanks..the community lives because people like you.
Ive solvend the problem....after 2 times wiping all... the only backup which is working flawless is my old stock sense, all other cm7 backups reboot after using mobile data connection. When i wipe all and install a clean cm7 nightly 204 ...its working too, but at moment ive no time to install everything, so i will keep the stock sense for some days.
The wired thing is...that this bug appears after i updated from the 202nightly to 204 and especially wired is that all my cm7 backups are now affected by this problem that never happend in the past.

[Q] Unable to connect to mobile data

I finally got superuser working by flashing Echoe Illusion, the full touch-wiz version with Android 4.3. At first it seemed like I had everything working but the next day when I left the house (no longer connected to home wifi) I quickly realized it was refusing to connect to mobile data. I also cannot send text messages, and likewise I can assume I can't get them either. I have tried flashing the nightly CM11 build and 3G connected although LTE did not. I wasn't in an area where I expected reliable LTE anyway so that's not even an issue at this point because I'd very much like to use this Echoe Illusion rom, or another Touch-wiz based one. I just can't go downloading a bunch of them because I have a severe restriction on data usage and have already downloaded Echoe Illusion AND multiple other things. If it matters, my baseband ends in MJA.
I have also attempted to flash different modems with Odin, although all of them failed completely to flash at all and at this point I have to honestly admit I don't know what I'm doing. This is most definitely not my first time rooting...I'm just used to HTC phones, the Evos in particular. Thanks in advance if anyone can help or provide useful tips!
oh and P.S. I can't go back to the stock firmware because I must have flashed an incorrect kernel, and it borked the phone. I only got it working again by flashing a separate rom (Echoe Illusion) and have since flashed other kernels with no ill effect. I had a nandroid backup of the stock rom before I borked it, but every time I try restoring it, it stops at the yellow Sprint screen and won't boot.

[Q] Why does my Wifi & Bluetooth not working even with stock rom?

Hey guys,
I have a Galaxy S4 (i9500). I installed Omega ROM v22 on it and everything went smoothly, Wifi & BT working perfectly.
After a few hours of using the device (nothing special at all, texts and stuff like that) - I noticed my wifi isn't working and by not working I mean that I click the wi-fi button and it changes from gray to the mid-state between gray to green for around 20 seconds before it goes back to green ago.
If I open the menu to see my networks it just says "Enabling" without any networks there.
I had to drive somewhere so I went to my car and tried to enable Bluetooth, and same thing happens there - Bluetooth will not turn on and will stay stuck on mid-state between gray and green for a while and go back to green.
I flashed omega rom v22 again and the problem was gone, or so I thought. I went back to the car for another drive and realized the bluetooth issue is back - and when I got home I realized the wifi issue is back as well.
I figured I need to reset everything so I tried the following:
Full wipe (including dalvik and even including "internal SD card") and then flashing stock rom (from the official website, stock rom of my country).
The issue was back after a few hours. I do not have BT or Wifi access. Yesterday Wifi suddenly started working for a few hours but then it stopped working again.
I really need help! I have no idea what to do with this issue!
Well rule number one when you have problems after flashing without wipe.
1. perform a full wipe and see if the problem persists.

Tried that, no luck.
What else would you try?
In some places when people had problems with Wi-Fi they said to flash a different kernel but I don't see why I would have this specific issue with Omega Rom and why the default kernel with it wont work well?
Maybe this could be a root issue? My root works fine but I have this weird gut feeling like this is some permissions thing that's going on.
I'm trying to think why it would work right after the wipe but then stop working shortly after.
Another symptom: It randomly started working for a few minutes and then stopped again (around three hours ago).
Any idea what's going on?
Well, if you fully wiped and didn't restore any apps and settings then it can be two other things.
Or it's a bug in the rom or a hardware failure in your phone.
I would suggest trying a different rom first. Do not restore anything, not even your google account.
wi-fi fix?
Do you actually have an i9505? or is it a canadian or att version? if its the latter sometimes the devs offer some wifi-fixes, also try a different kernel. otherwise it could be that your radio/modem are not compatible with the version of the ROM you are flashing.
Tried arrow ROM and this issue doesn't seem to happen in this rom. Hope it stays like that...

Sadly, it did happen with this rom, after just a few hours.
I'm now using stock rom and still suffering from the issue.
Does anyone have ANY idea what I can do to fix this?

[Q] No network service GT-S7710 after installing CM10.1, 10.2 or 11

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 .

http://forum.cyanogenmod.org/topic/85051-no-service-cant-calltextnetwork-after-flashing-cm11-nightly-on-i9305/
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.
