I have Lg l7 P700 with 4.1.2 v20a europe open, and ocasionali it just lose gsm signal, and shows no network coverage. Noting helps except restarting phone. any ideas???
p.s. sorry for bad english
Hi have also experienced this especially when running GSM only mode. But when on the others the network is abit stable. I don't remember this sort of problem on ICS so it is possible v20a might be the culprit. May be refrashing might solve the issue.

Hi all i got a defy green lense and having signal problems.
I have been using cm7 and now cm7.2 since using non stock roms my signal has been playing up majorly.
Sometimes cant get a signal other times i'll get a signal but only hold for a while
Most annoying the signal "unlocks" when the screen locks and then takes ages to lock back in again.
3g problems too.
I have tried all the basebands and different sim cards and networks but still the same (ok when i put into another phone).
I have checked inside the phone (had to replace ear piece again) and nothing is broken or dirty.
i did read somewhere that it could be the radio files on the phone but i thought baseband swithcer did this?
Any help would be great as its getting annoying now also i noticed wifi locks out sometimes too when screen in locked?

What service provider? Where are you living?
I was facing a network issue too. I had to switch my baseband to "China MEE 810/2100" as i use VODAFONE IN
see with your network provider if you have set the correct baseband for your area
I've done all that and it has the same problem on any network and Sim.

WOW this prob just hit my phone this morning.
i went to sleep last night and everything was fine
woke up this morning and had no data and my defy says Emergencies calls only.
i tried putting my Sim into a g2 and works perfect. tried resetting the defy and changing the base band and nothing... only one that lets me make calls and gives me 2g is Australia base band. i even flashed a fresh sbf and im still having the same issues.
if anyone out there knows how to fix this issue please let me know i really need my 3g back.

HELP! SOS!
I'm not too worried about the 3g it's more the annoyance of the signal cutting in and out.
Is there a way can change the radio files on the phone without using Baseband switcher so I know it's actually changed then and not looking at lots of files?

Visit the below mentioned link and use baseband switcher tool and try switching between US T-Mobile 3.4.2-107-4 @ 850/1700/2100MHz
or
US T-Mobile 3.4.2-107-9 @ 850/1700/2100MHz
or
US T-Mobile 6.xx.0 @ 850/1700/2100MHz :

Also make sure that your phone is not in Airplane mode from Settings
Use the steps and share the results!
Tried the baseband already, put stock rom on and the signal is better nopt switching on and off so why does this happen on cm7 etc?
Just an update on this...
Flashed phone to cee deblur stock rom and signal was OK so worked out it must be a software rather than hardware issue.
So using the PC method I flashed the phone 3 times and wiped all the data each time.
After that the signal was still OK so I install 2ndinst and loaded cm9 cm9 kernel and gapps. Wiped data and the phone has been fine apart from 2 lock ups. I'm getting 3g and the signal is not being lost. After installing cm9 I also installed rom updater ,after 1st reboot it updated Android and now my camera green lenses works too not 100% quality but that's what my dslr is for! So for people getting the signal being lost abd no 3g problem try a stock rom a few times and wiping phone then custom rom worked for me!

Hello,
i have the same Problem with Defy+.
I have T-Mobile Germany.
I have tried all basebands, but when i lost the signal, then i dont get it the next one hour.
What ca i do?
Czech republic signal issue
Hi,
I have signal problems too - Vodafone CZ user. When I have no signal uderground - when I go down by escalator signal just disappears. Its verry annoying in case of using mobil tickets.
Im using WajkIUI™ ROM based on MiuiAndroid 2.3.7 (GB) on Defy+.
Have you any sollution for this?
Thank you
I have the same problem. There is no signal in underground or even in elevator! I checked it with cm7 and whiterabbit. I think it doesn't depend on rom. But I believe it's software problem.
Problem in Base Bands
I have problems when I switch to 850-1900 frequencies, the ones that works in America, Argentina.
I tried everything, differents roms, stock roms for Arg carrries. APN are correct, Baseband selector for Defy is correct, set to Americas, argentina,
I bough this phone from ebay, it seems to have been designed for UK Ireland according to motorola support, I haven't reached the UK support because they're currently closed.
When I am in 900-2100 Bands the phone works perfect EXCEPT for 3G, H Connections that don't work at all.
Is it possible that this phone has a different hardware ? I read that it may can be solved with a new Base Band for America but how do I go with this?
Thanks

Hi, It looks like the problem I have and which is location dependent but for me 2G works better than 3G. It seems that the Defy or CM10 is not working good in circumstances were it switches from one network technique to another. Reboots I have:
Reboot after switching automatically Wifi on with Easy Profiles. Effectively it then shuts down 2G/3G because Wifi is switched on.
At my work where we have indoor coverage with 2G antenna's. Much less reboots there if I put the phone on 2G only.
Some reboots I can't explain
I log my reboots with reboot logger from the play store. Pictures in Play store are not English but app is in English. Handy app!
I did play with several basebands but in the end the default baseband for my location worked best (3.4.2-145 Central Europe). More frequent reboots with others or the went info flightmode spontaneous.
No solution but you could play with the following settings:
Settings - In Wireless & Networks: More - Mobile neworks:
National data roaming
GSM//UMTS Network preference
Use only 2G networks
I did not find a combination which ends rebooting once in a while (a little less than one time a day on average).

[Q] DefyPlus Root successful(?) 2g-GPRS messed up-Please Help
@Mods: If this thread is not placed appropriately kind move/merge as appropriate. I did try to search for this peculiar problem but was not successful. Thank you.
Hello everyone,
Today I pulled the trigger and rooted my Defy Plus inspite of all the misgivings I had about my ability to carry it off successfully. And in hindsight my misgivings seem to be very justified.
The details of my device are:
Build # 4.5.1-134_DFP-231 & Android ver 2.3.6
SBF : 45.0.2310.MB526.AsiaRetail.en.03
The rooting guide I followed was as per http://forum.xda-developers.com/showthread.php?t=1542956
Recommended SBF's were downloaded and the method outlined followed
The long and short of it is:
*Most likely the rooting has been successful - How do I know? Well I installed a screenshot application from Google which needs a rooted device and it said my device is rooted and it worked successfully.
* The problem? The problem is, my primary objective to root the phone was to enable some call recording app or the other to work and if that did not work go for WIUI GB or ICS custom ROM which if I understand correctly is configured to allow call recording. My data usage is minimal at best restricted to some emails , work related browsing when I am away from my office. For this I use a 2g connection and that suffices. However after the rooting if the network is set for 2g the device does not list my service provider, even if I do a manual search for service provider. The very same phone works flawlessly if I opt for automatic network selection and it defaults to 3g which I do not want due to cost implications.
Now is there a way to resolve this issue without rooting a custom rom? Or do I need to flash a custom Rom that to extricate myself from this mess? Or do I need to go back to factory settings using SBF the device is shipped with?
Thanks in advance for any help
Success - Baseband reset for India
I was facing the same issue , after rooting my phone as indicated in my earlier post.
Subsequent to that I installed WIUI Rom - the stable version - from here, and used the inbuilt Baseband utility to reset baseband for India. Issue resolved.
Hi... I recently upgraded to 4.3 and have tried both radios .84 and .83... the problem is that when my phone is on 2g/3g mode, the signal sometimes just drops and refuses to come back.. it does not even come back if I try to manually register on my network (i.e. Vodafone Mumbai) and gives me an error 'failed to register on the network'... however if I put my phone in 2g only mode, it instantly picks up signal and does not drop it... anyone else from Mumbai can confirm whether they are facing any network issues after upgrading the radio?? I have read on internet that it might be related to radio.. also, I have also tried replacing my manually cut sim by an authentic micro-sim from vodafone but to no avail... now I might try reverting back to 4.2.2 to see whether the issue is radio related...

Hi experts,
im using lg l7..... 4.2.1 my problem is its often lost the network and will come back later.....
can any one help me to fix this plz
Had this problem with stock rom and the only think that I found fixing it was turning on mobile data for a sec and signal reception was back
Hello i have a stock LG G2. I bought it second handed but it is in pretty good condition. I have one really annoying problem though, which seems to affect a lot of LG G2 users.
When i am connected to mobile data connection, the connection drops frequently. I've read that this is an issue with the latest update.
Is there any fix for the problem? I tried turning air plane mode on and off but, hard reset but non of these helps.
If i root my phone will i be able to fix the problem ?
Im really desperate, as i am using mobile network a lot.
Thank you
I remember it being a problem with the Jelly Bean ROMs, but only the earliest ones. I'd try flashing a stock ROM specifically for that device, or try disabling (or enabling if it's disabled) fast dormancy in the hidden menu, might help.
Please tell us specific details about the phone and ROM specs.
