Hi,
following problem to my LG P930:
I got it as a present because my old phone was crashed. First I wanted to do with the P930 is to get root access and flash CM to it. This was difficult enough, but now I have a problem where I coundn´t find any information.
With original firmware (I think it was 2.2.6 or 2.3.6) LTE was working. Now, with the last CM 11 and with CM 10.2 LTE dowesn´t work. I can ping any homepage with the terminal, but the speed for downloading is just at 40k/s, really really slowly.
I found, that maybe LTE must be unlocked by an unlock-code. Therefore I have to open a menu under the number 2945#*930#, but when I call this, just the msg appears, "Connection problem or invalid MMI code". Most of all #* calls do not work at all!
I tried to fix it, but all methods I found are for MTK devices, but the P930 has a snapdragon cip.
The *#06# call works, my IMEI is valid, I can make calls and send sms, the Internet works, but much too slow for daily use. My Sim Card gets access to o2 network in Germany.
I tried 3 CM ROMS and different settings in APN and mobile networks, but nothing works.
I tried to get network access with a Telekom SIM, but there I couldn´t get any access, so I wasn´t able to make calls, neither sms nor Internet.
does anyone have an Idee how to solve this issue?
PS: only thing I found is in this thread, is to rename modemfs folder.
But I don´t understand what eduds mean in post 8, and his problem was an other, because his mobile data doesn´t work at nothing.

Hi,
I`ve succesfully installed RC3.1 as described in the thread elsewhere on these boards.
However, I do not have any mobile network coverage and cannot text or message.
I have updated the kernal as well, used the one on the same page as instructions for installing ICS.
Anyone have any idea how I can fix this or whats gone wrong? I like the look of Android 4, but its not much use without network coverage.
Many thanks
I`ve found this as a solution to the lack of mobile network, but I dont exactly understand what it means!
Could someone spell it out for me in with step by step laymens terms!
Just wanted to add that the 3g appears to be working since I am receiving emails through gmail via the phone.
My IMEI number is showig and it says mobile network state as connected.
Mobile Network type is UMTS:3
Under Service Status though it says `Out of Service`
Is there any way Orange would be able to block my phone been used with ICS? Because thats what it seems like. If I revert back to Gingerbread everything works again, but I like this ICS and would rather keep it if possible.
Thanks again for any advice
I'm having the same problem. 4.0.3 rc4.2 from sgssgs.
Hi everyone,
I recently bought the phone from T-Dimension and it's having some issues and I was wondering if anyone could help me out or if they've run into something similar. The issue is I can't seem to send/receive any calls and I can't send/receive any texts. The bizarre thing is it works for the first 45 seconds when I reboot but then locks me out straight after that. The phone is issued from Hong Kong and had Color OS on it but I flashed CyanogenMod onto it, here's some more information.
- The phone is connected to Amaysim, which runs of the Optus network I believe, so it's connected onto the mobile network just fine.
- The Micro-SIM card I'm using is brand new, it's put in correctly into the slot, meaning upside down facing towards the bottom of the phone, so that's fine.
- I've tested the SIM with other phones and it works perfectly fine.
- When it locks me after 45 seconds, it fluctuates from saying, "Call Not Sent" to just it being stuck on the dialling screen.
- After being locked out, I can't receive any calls either, I've tried calling the phone but nothing shows up.
- After being locked out, I can't receive any messages either, when I try to send a message it just stays stuck in sending, and if I restart the phone, it just says the text failed.
- I've contacted Amaysim Help Desk, and they say my problems lie with the phone being locked, and I'll have to contact the manufacturer to sort it out.
- I've also contacted my supplier, who seems to have trouble finding out the issue.
- APN settings are set correctly with my mobile carrier.
- Already done a factory reset, didn't fix the issue.
- Put the preferred network type to 3G under Mobile Network settings.
- I flashed CyanogenMod 11S using this tutorial from youtube, /watch?v=QDKOEtN9pbo and downloaded the cm-11.0-XNPH22R-bacon-signed.zip file.
Please can anyone help me with issue, sorry for long wall of text, I really want this phone to work!
Cheers,
You probably should flash another modem & then try.Here

That modem actually proved to be worse for me.. Before I didnt have stable 3G connection.. that modem made my 4G connection worse too. The best, and most stable modem I have found thus far is in the latest nightlies. It is still very very very weak when it comes to 3G connectivity but its better than everything else I have tried. And believe me, I have tried pretty much every rom there is on this forum including XNPH22R, XNPH25R, MahdiRom, CyanHacker, and All the nightlys.
The only one I havent tried is Color OS because I am afraid it will lock my bootloader again.
i have been facing this problem from the last 5 days. i have no network in my samsung sgh t959 phone usually i used t get this problem bt then it the network used to come back automatically
bt now since 5 days there has been no network in my phone i tried every single thing i did a factory reset, tried changing sims, when to mobile network ad searched for network,did a ping test run selected every single mode (cdms gsm lte etc) even did turn off radio . i even i checked with the imei my phone is displaying the imei properly .i guess there is no corruption in my imei
so please can anyone help me with this issue. i am still looking fo a perfect solution for this issue.

Hello, Recently I have bought an Unlocked At&T LG G3 The seller told me that the phone has a bad IMEI But it's unlocked to be used interntionally. When I received it, It's working fine, except the data network speed trough EDGE is too slow. As yo can see on the screenshot below I couldn't find the option to change the network type. and I'm stuck at "E" which mean EDGE.
http://s14.postimg.org/8r7vs0x27/Quick_Memo_2015_09_09_11_41_43_1.png
The phone's model is LG-D850 and it's running android 4.4.2 KitKat. it has no IMEI when I dial *#06# it shows IMEI: 0-05 on Settings/about phone/Status... it says IMEI: 0
Anyone here to help?
First, here are the possible reasons why you don't have an IMEI:
The phone was reported lost or stolen in the past.
The phone is still active on the owner's wireless carrier account.
There is money owed on the wireless carrier account to which the ESN/MEID/IMEI is connected.
For the reasons above, this community does not support such devices and you will probably not get any help.
But, this can also happen during a bad flash, so to fix the issue, you have 3 options:
Reset, unroot, then root and flash again

Thanks for your reply, I'm not seeking to restore the IMEI. I just want to have the option to switch mobile network type. Should I root the phone and install a custom ROM?

My bad, thought you wanted the IMEI back. In that case, the E (edge) is showing up could be due to Maroc Telecom throttling your connection or their towers could be far way (happens when you travel cross country too). Anyway, if you want to fiddle with network settings and try to get it to work BEFORE attempting to flash any ROM, try the following [3845#*855# 3845#*850#] USSD code from your stock dialer. You will get a hidden menu containing a juicy list of options and settings, so what you are probably looking for is the "LTE-Only" option (I am not sure though, but you can look through the settings).
And as always, attempt the suggestions AT YOUR OWN RISK.

I'm living at a major city, here the 4G works great. So yeah I have to change the mobile network type since it is on EDGE by defaut I guess.
I attemted the USSD code however it says "connection problem or invalid mmi code" after I hit dial. I have also tried a bunch of codes before but no luck.
I think I will falsh the phone that's the option left. I just have rooted the phone, then I will install TWRP and I will try to flash a ROM in it. What do youu suggest me to use from those ROMs posted here ?

I get the same error if I use a third party dialer app (i.e., Dialer) until I tried the stock phone app.

I haven't flashed any custom ROMs on my LG, but from experience, each device somehow reacts differently to custom ROMs. For instance, I've flashed my S.G. Note (i717) over 30 times and some ROMs were stable at first then started having issues with them.
The best advice I can give you, is to pick a ROM from the list you posted and check the comments to see if it is stable or too many users have issues with it.

Ever think that it does not have the correct bands for your carrier?
Hello out there..
First i have to say sorry for my bad english..
last week i bought a HUAWEI Mobile Wifi E5577C and it works really fine.
But...
The SIM i entered is a so called "Ultracard" by the german Provider "Vodafone". Ultracard means that you can get up to 3 cards for 1 mobile Number.
the first card stucks in my mobile and the second in the mobile Hotspot.
Internet works fine, thats not the problem... The Problem ist that when i get called my phine doesn`t ring !!!!
When you get more Cards for one Number than the call is getting out to every card at the same time.
The HUAWEI E5577C uses Data AND Speech Channel and so caller gets the sign that my phone is busy because of the used speech Channel at the Hotspoot.
Does anybody knows a solution for this Problem?
By the way... when i plugg the Hotspot at my PC it isnt shown as a modem, so the solutions wich i have found in the web doesnt work.
Thank you
Greetings
