Go back to stock and see if that helps.

Did you flash the PROPER ROM for your device..? Hope you made a backup.. Restore it obv and see if that helps. But before you do, check out your mobile network settings and make sure everything looks right..

[HELP] M2 don't connect to network after installing GB[SOLVED]

I need help guys!
I installed motogingerbeta5 and everything worked great.
After a reboot my phone doesn't connect to the network (no 3g, no edge, nothing!) .
I tried baseband switcher, defy app that comes with GB and didn't work.
So i flashed brazil sbf and restored my nandroid backup (restoring my phone just before i tried GB leak). I was using argen2stone 1.9 before.
but the problem persists.
I tried the sim on another phone and it works perfectly.
PLease I need help from you guys I'm desperate, don't know what to do.
thank you!
EDIT:
Found the solution here:

Try using APN Brasil
Sent from my A953 using XDA App
I'll try it but I'm from europe (spain). Lets see if it works.
Thanks for the answer
EDIT: It seems that that app dont work in my moto
configure the apn manually
done but no luck.
The phone doesn't connect to the network. APN is only for mobile internet
I can't make calls.
I think the problem is from the "driver" of the baseband. Is there any diagnose tool?
Can someone make a nandroid backup of an european froyo or gingerbread and upload it here? Is possible that a dev help me please?
Thankyou
hey there,
try the solution from this thread : http://forum.xda-developers.com/showthread.php?t=1182050
I played a bit with the defy baseband switcher and lost network on GB as well. This worked like a charm
Wish you luck!
That did the trick! thank you so much!!!!!!!!

[Q] LG G2 D806 ROM/Support/Compatibility

Hi there =)
Ive seen a los of roms and modifications for the LG G2 phone, mostly everysingle other number than mine, i have the d806 Argentina Latin America version i guess, and i havent been able to find any compatibility list or something like that to know wich roms (if any) of the other models can be installed on this one.
I would really like some help here since the bloatware haters (like myself) want to go to paranoid or a more stocky kind of android. Ive search the forum and the only thing ive found is the root tutorial on d802 working for the d806 but nothing about roms. If you guys can help me (and i bet a lot other too) out and help me figure out wich roms can work for the d806 i would be amazingly happy.
Thanks in advance.
Cheers.
Before you try this make sure you have a recovery and back up!!! I use international roms on my tmo g2. I do this by flashing the rom then immediately with a reboot i flash a kernal for my version. I would try this. ONCE AGAIN PLS MAKE SURE YOU HAVE A RCOVERY AND A BACK OF A WORKING ROM! You can also choose to use your stock kernal my making a back up. And then flashing your backed up zip right after your rom

[Q] what should i backup before downgrading from 4.3 ?

i know there are serious problems happening when downgrading from 4.3
it happened to me a week ago on my i9500
i flash MIUI V5 and lost my imei , had to send it to a friend which fixed it in his lab
im not giving up though, i really like and used to MIUI and still want it, the question is how to avoid that from happening again, what did i do wrong ?
and worst case scenario it happens again, what should i backup exactly ?
ive installed andromizer and backed up my EFS , does this backup include both my IMEI and SN ? should i do anything else before trying again ?

I think it's a matter baseband
Stock-based MIUI rom touchwiz 4.2.2
And you are of 4.3,
Already trying to restore a EFS backup?
Note: sorry if im wrong

Baseband=modem?
Anyway i tried flashing miui, couple of versions of it, and ended up with the same results
No outgoing calls when on miui, incoming ok, sms, internet, just no outgoing
Imei and sn are intact, things got back to normal only when i flash stock 4.3 rom
I want miui :-\ what am i doing wrong?
There is no turning back. Install the MI launcher instead or any MIUI theme for launchers.
P.S. I have tried MIUI. Good but not as good as what they say.

thats weird, i ran into some people running 4.2 on their i9500
not MIUI but other versions which worked perfectly
youre telling me im stuck with 4.3 and newer ?
edit :
what about this method
http://forum.xda-developers.com/showthread.php?t=1658809
can i just pull the baseband from the stock rom and flash it on my phone once i have miui ?
would that work ?

No, you're not stuck. I've been using MIUI v5 and stock 4.3 back and forth testing which one is better. Personally, i like the interface of MIUI especially the icons BUT there's so much jitter and random reboots every now and then. Wait for the Kitkat release of MIUI.
Why would you change the baseband? o.o

i can get calls and send sms but no outgoing

I just flash MIUI and i'm good to go. What carrier are you on?

[q] help please!

Hi, guys im having some issues and would like some expertise. Okay so i have an s4 the model is m919v but the model is unrelated to the problem. I was running custom roms and have been for a few months and i have a phone that has a locked sim. I heard from someone that i can flash an older version of my modem and get the service menu to unlock... point is i did it and it didnt unlock BUT THATS NOT MY ISSUE. I decided to then revert to stock because my phone was being really glitchy after i tried the unlock. Now i restored my phone and got a custom recovery installed a custom rom that was working flawlessly before is now also being glitchy the same way after i tried to unlock it,
These are some glitches im experiencing:
1) phone app is taking a long time to load and it doesnt type in numbers fast
2) when i call someone it just freezes and i cant go to the call screen
3) no notification sounds coming from my phone it just vibrates but doesnt ring
and im sure a few more
IM SURE THESE HAPPENED AFTER I WENT INTO THE SERVICE MENU AND TRIED TO UNLOCK MY DEVICE.
Someone please tell me what i can do to fix this because ive already reverted to stock once.
EDIT: omg MY CAMERA ISNT WORKING EITHER! PLEASE SOMEONE HELP IM SCARED

loss vibrat in i9500

Hello every one ...I got new problem in my new phone s4 i9500 ..suddenly loss vibrat touch during using the phone in custom rom ...I flash sokp at first custom rom and got that issue then flash hassan rom based on stock at first flash the issue present but flash it again and then work after that flashed aicp rom and after some days today the vibrat gone even in recovery mode ...what can be the problem ? My phone still new 1month ago ..can it be from kernal philiz ?? Thanks for any suggestion
any suggestion or throw my phone from window ......software or hardware problem ?????
Hi Ammar,
I think your problem is in software. If I were you, I install cwm or twrp recovery, do all wipes including system, preload and internal memory, then flash the latest official firmware with Odin. If problem stands still, I do all wipes agaün and install the latest official firmware again. Even if this is does not work then I decide the problem is hardware based.

Well I cant comment on what went wrong.
I was on slim rom once and my vibration Intensity was tooo too low. Because of that was missing calls.
Or you can download an app for checking vibration. Once my proximity sensor and speaker stopped working, i ran a test and everything was back to normal.
Try test you android from the playstore and see if that test works.
Well here is the app
But again as I said, let us know if this is happening on the stock rom.

Once my Wi-Fi stopped working on a Cyanogenmod based rom. I flased stock firmware many times but it didn't work. Then I installed cwm recovery and do all wipes then it worked. As you understand, such wierd things might happen sometimes that we couldn't understand.
i sent my phone to company and told me that vibrate engine is broken and they change it and now work good but what is the problem that caused this i dont know exactly ...as they said either by drop the phone or by water but non of these happend with my new phone
thanks guys for help

We are human being and as you know human is not perfect. So anything produced by human is not perfect naturally. If you could't find a reason for fault of a device then this is the only and certain reason :laugh::good:
