So I faced the no network signal issue yet again today, and I know I may be the Nth guy who's repeating it again, but since I searched throughout the forums, and the web, but to no avail, I desperately need help here.
Mine is a Defy+, with stock rooted 2.3.4 Asia retail unlocked. My carrier is Vodafone India.
This is what I did:
- Took a backup of everything, even nandroid.
- Installed Defy 2ndinit, and got the bootmenu installed.
- Reboot>vol down on blue led>bootmenu>recovery>custom recovery
- Here I did a factory setting>Wipe Data>Wipe Dalvik Cache>Wipe Cache.
- Next>Install zip from sd>11.10 JB Defy+ Quark's ROM>Update v2>Custom GAPPS
- At this point, the phone rebooted coz there was no other option.
At first boot, it took a loooooooong time, but finally I booted into JB! Result!
But alas, there was no network signal to be found, while my other vodafone india handset had full signal.
Hence, I couldn't set up my google account, and thought, that I could fix it once I proceed.
- I tried the airplane mode on/off method: No success.
- I tried rebooting several times: No success
- I tried clearing cache & dalvik cache and then rebooting: No success
- I tried fiddling with the baseband switcher, and trying different profiles, other countries etc etc: No success.
- The phone wouldn't connect to the WEP, WPA2, or No authentication(open) ad-hoc wi-fi interent connections that I shared via my laptop either. It easily connected earlier on GB 2.3.4 stock.
- I tried manually searching for a network as well, and found EVERY network EXCEPT for Vodafone India, which my sim could register to. This, while my other vodafone phone was lying right beside it with FULL signal.
The ROM was working beautifully, with all the bells and whistles, albeit a bit laggy, but that could easily be fixed later. The main problem being that this issue, doesn't lemme get data access on my phone either, so its essentially just a dumb-phone then.
This had happened earlier as well, when I had tried to multi-boot ICS CM9, with my stock 2.3.4
Then, I couldnt part with the stock ROM, and hence I believed that the no network issue could be due to multi-booting, and would be resolved with a complete install.
Now, I love JB, and everything it comes with, but I am stuck with this essentially simple issue. Please help me out here.
Hey gautam,
i have a defy on vodafone mumbai (not a defy+) and i dont seem to have a problem. I hadvent used CM10 i was on 7.2 and i used central europe as my baseband in the baseband switcher. But actually i had signal straight out of the box with 7.2. I would suggest you try with another sim card. Or try downgrading. It could be because 11.10 is custom kernel one but nogoodusername is also an indian and is using custom kernels. I doubt its a baseband problem because you can see and register on other networks. I think possibly something was corrupted by your install since not even your wifi is not working some radio drivers could be bugged.
If its not your sim a reflash of OS might be required. If you're downgrading to GB you may need to reflash your kernel to get off Quarx's

Will try and find out if this works..
Please keep sharing any other solutions in case this doesn't work..
If you have IMEI number use Baseband switcher , play with is a little bit.
if not , backup your rom , flash stock SBF. <wipes and all with stock recovery>
boot to stock FW , and now you 2 options :
Case 1:- You don't have signal , and even if you don't have IMEI number in stock , root it and use the baseband switcher on the stock , make sure you reboot every BB switch , and that Signal bar even tries to increase <even a little bit.>
Case 2:- You have signal .
please try these steps to get network

Thanks, It resolved weak network issue which I was facing from last 2-3 weeks
Hello, I had successfully flashed my LG G2 (D802) from stock to CM 10.2. The sim card was recognised and joined immediately to EE (UK - Mobile Network *T-Mobile/Orange*). During Christmas I tried flashing a new nightly from Cyanogen Mod (11), however I had an outdated clockworkmod version (even though I couldn't update it further). I couldn't launch back to CM 10.2, as the data was wiped when trying to flash CM 11 (Nightly).
Due to not having a back up file, I reverted to factory settings first, then wipe 'all' data off my phone using ALL the options avaliable on CWM. I then had to use 'adb' to push CM 10.2 back into to the phone. It successfully flashed and it was running stably. During the set up pages, CM gave me a pop up to look at sim card instructions to 'get it working', i thought this was a minor problem and couldn't to set it up. When this was finished, gave me everything (WI-FI, bluetooth etc.), however I didn't connect to my Mobile Network 'EE'.
I set 'Data Enabled', Network Mode: WCDMA Preferred.
I tried automatically/manually connecting via the CM settings, but response was 'Could not connect to this network. Please try again later.'
So no luck so far in connecting the phone function back up.
I would be truly thankful if everyone could help with a solution. ^_^
Many Thanks!
I've found out that the phone is locked to a HK network, but I am currently studying in the UK. The problem is that I can't unlock the phone in the UK with using the HK network; I have a HK sim card as well as UK, but since the phone is locked I can't use a UK sim card and the HK sim card doesn't seems to register UK Networks.
Anyone got suggestions to bypass this?
Today i installed G2 pro rom (from here: http://forum.xda-developers.com/showthread.php?t=2673143) and after that i lost my network. I went back to 4.2.2 stock, but still no signal. Then i tried Paranoid and flashed also with no modem, but still no luck. I can see my imei and i can find diffrent network operators in mobile network setting but i cant register to anywhere, phone doesn't detect sim. I tried sim in other phones and it worked. If anybody got somekind of suggestions, then please help! (im on d802 16gb and i bought it from estonia)
Hi all,
I've had my phone locked on Tele2 (CRO) network which I needed to unlock to be able to use T-mobile SIM. I've used Odin 3.04 and followed the instructions to update modem to I9505XXUFNB9. I've managed to unlock the network this way and use my new SIM but the connection (both phone and mobile data) kept switching on and off constantly.
After that I've tried another firmware, namely I9505XXUFNDG for T-mobile but the problem now is that mobile is almost always off with no possiblity to connect and WiFi is blocked completely (security notification "Your device's security has blocked an action").
Basebands registered properly after every flash.
Phone is not rooted and me not being a power user would just love it to work as it was intended to
Followed the guide, all firmwares downloaded from here
Appreciate any help.
Might be onto something. After reading through this post seems I need to apply WiFi fix but I cannot tell which one to use for my phone (I9505XXUFNDG) as it's not posted. Kernel version 3.4.0-481100.
I've tried I9505_WiFi_FIX_MDM.tar and I9505_WiFi_FIX_MDF.tar but they just messed up the phone completely.
Thx a lot.

Hi ,
you should flash the fix for the modem you have installed , try following:
Flash another modem from the list there
Now flash the modem wifi fix for that modem
If still in trouble re flash stock and start all over again.....

Thx, did just that and now it works properly.
Much obliged.
a problem started to show recently; when i select LTE/WCDMA/GSM for auto connect network mode when the mode switches due to signal availability it doesn't get reconnected. i.e. while under LTE it works fine but if i move and get out of reach it should automatically switch to slower network which it doesn't. this works fine if i select WCDMA/GSM then the switches are fine but LTE is not available under this.
one more thing i noticed since i'+ve flashed the phone is that the upper part of the phone gets very very hot (a lot more than before). since the flash i've also had to replace a microSD card which died within weeks (not necessarily connected but worth noting).
any suggestions welcome.
Android: 4.4.2
Baseband: I9505XXUFNB9
Kernel: 3.4.0-481100
My vs980 has no signal and i cannot change the network mode from GLOBAL in settings. I was previously on an older unofficial cm13 with working tmobile service, then i stopped using the phone and came back to it a while later and flashed the latest crDroid nightly (12/12/15) and never looked at the phone again until now, when i realized there is no signal.
I have tried different inactive Verizon and t-mobile sims, yet the phone still says no service emergency calls only, and network is stuck on global. I have tried a modem and efs restore through twrp, and even flashing back to stock to no avail. The phone does have an imei still, which is a good sign however i am all out of ideas for fixing this.
Try flashing stock KDZ. If it won't help, then very well could be hardware failure.
Try flashin stock kdz (maybe your imei has been deleted) ( and sorry for my english?)
