Phone wont connect to network when i flash a custom rom - T-Mobile LG G3

I have the lg g3 t-mobile version. I recently bought it off eBay and im located within the UK meaning i will be using a UK network. For some reason on stock it has no problem connecting to the network however on any custom rom i have tried (one was cm13 nightly , the other being resurrection) it says 'cannot connect to the network please try again later) . Any help would be much appreciated

Try this, flash or restore your stock ROM, and check IMEI. If it displays 0, then i guess thats the reason why.

Optimus G Pro KitKat 4.4.2 manual network search bug

Everyone,
I just updated my firmware to 4.4.2 via the LG software (South East Asia version). What I found out is that I can no longer manually search for telco network and pick the network of my choice. It will always present "No Networks Found" when I attempt to search. Auto network selection works fine. However, I need to search and select manual network due to the network alliance for data roaming.
I send my phone in to the service center and they tested it with different phones and found that it is consistent and they declare that it is a bug in the KitKat firmware. They downgraded my phone back to 4.1.2 and tell me that they will feedback the bug to the software team, however there is no commitment on when this will be fixed.
Please help me test the manual network search on your 4.4.2 and let me know if you face the same "No Networks Found" issue. I want to know if this is limited to the South East Asia version of the firmware or it is bigger.
Thank you.
I had this problem too. I was using the Singapore E988 and when I upgraded it to 4.4.2, the phone could not display the available telco networks in all modes (GSM, WCDMA, LTE...). Either it gives "no network found" or "error while searching for networks."
Tried resetting to factory numerous times and reinstalling 4.4.2, but it doesn't solve the problem.
I had to downgrade it back to 4.1.2 and everything is back to normal.

Thanks for the confirmation. Hopefully LG will fix this in 4.4.2 so that we have a functioning KitKat to use on our phone.
Cheers!

Nope. Not yet, at least for Singapore firmware. It is still the v20b created in May.
I think LG has decided that it is not worth the effort to fix this. I am stuck.
I am considering flashing my phone with KitKat firmware from Hong Kong or Malaysia, not sure if it is a viable option.
Are you also experiencing the same issue? Which firmware are you using?
Im in south Korea and my phone also shows no signal inside rooms, restaurant,ets.. im think it getting LTE signal only?..

[Q] No HSPA+ after Kitkat update

Using official (as well as silviu's ROM) for Samsung Galaxy S4 mIni duos (i9192) on Jelly Bean, I could use HSPA+ network (when available). However my phone was rebooting everytime I activated my 3G/HSPA+ on one of the two sim cards... very annoying, my only solution was to deactivate 3G and work on Wi-Fi to avoid constant rebooting.
Therefore I tried kitkat version : it's even worse concerning rebooting plus I have no HSPA+ at all (same phone, same sim card, same network, same place) !! Modified ROM of Silviu corrected rebooting issue, but still no HSPA+ anymore !!
Can someone help ?

Hello, thank you for your quick reply !
I'm from BELGIUM and tried a lot of things without success... you are my last hope to solve.
I'm afraid I was too fast in saying rebooting issue was solved with your kitkat rom : it is not rebooting but I still loose network on both sim cards after activating 3G on one of them (and using it). Behaviour is slightly different as I don't get immediately pin code screen or rebooting, but I have to reboot and enter pin codes again to reactivate network.
You may be right about changing modem : what do you suggest ? I found one of your posts on this forum with a lot of modems : are they all usable with kitkat ?

Strange behavior u have there. unfortunately no, only 3 modems for now for KitKat . Russia, India, Chile
I think i only had one full network drop on both SIM since Kitkat and that was caused by Phone.apk crash . But my network came back online in 10 15 seconds or so.
On Jb, i had more Phone.apk crashes but those fully lock the phone and i had to force shutdown . ~1 / week or so
I have no clue what to advise u unfortunately. Sorry
Did u try without PIN-codes ? I don`t use them

Yes, I tried... unsuccessfull
Let me resume, I have now 1 more issue on Kitkat comparing to JB :
a) loosing network when both sim cards active AND 3g active on one of them (i.e. be asked for pin codes, unexpected rebooting, just nothing to see but get voicemail when calling my own numbers from external phone)
b) no HSPA+ (Kitkat only)
I tried to downgrade to JB in order to have at least HSPA+, but it gives an error ! ?
Please help how to proceed for downgrade to JB stock rom ?!
Thank you

Hello
I've noticed there is a new version for India... do you have only the MODEM: I9192DDUCNH1 for download and is this modem compatible if I install it together with PDA I9192XXUCNG2 (I don't want to reinstall everything, but only have bugs corrected in modem) ??

Here u find almost all modems
Same issue here.
Same issue here. After upgrading to Kitkat, never been able to connect again to HSPA+ signal. When I try network mode "GSM/WCDMA" I get EDGE signal then when I choose network mode to "WCDMA" only, I have a signal but no internet and the symbol "H+" or "H" doesn't appear on the top of the screen.

[Q] I unlocked and rooted/flashed and now shows wrong network.

Hi guys,
I had my Note 2 on Koodo network for less than a year. Recently I unlocked it and sold it to a friend. My friend is on Videotron network and the phone shows the signal with an R like if my friend was roaming however it works properly. I also tried switching the network manually but it doesn't want to connect to Videotron. Is there something that I need to flash such as modem maybe ? It's running on Slimkat latest stable version.

[Q] UK 4G not working

So far, managed to root my Korean F240L, still running 4.4.2 for now until there's a root for Lollipop. Haven't managed to see any 4G signal in the UK since I got it , get 3G sporadically but the reception is way worse than the same sim card in my old Nexus 4. Network is Giff Gaff (ie O2) , should I consider going for a UK baseband update ?
Right ok, since found out that the Korean version doesn't support UK 4G. Is it possible to change this ?

If the phone doesn't support the LTE bands your desired carrier offers, then no, you're boned.
Think I'm in a similar situation
Got an E986 from Germany running 4.4.2 KitKat (E98620a-EUR-XX), it works great on 3G in the UK but NO 4G at all on my Three 4G Sim card. Tried enabling it in the hidden phone menu - no joy.
I thought I would be able to get 4G working by rooting and re-flashing but by god I cannot get this thing rooted despite my best attempts from trying all the techniques on here
Thought if I downgraded to 4.1.2 then I would have better luck rooting, but can't seem to download a .kdz that isn't corrupted when I try the LG FlashTool

You cant change the bands of a phone by flashing other things. If it doesnt work it most likely wont be able too.

LG G3 D851 shows full bar signals but no service

Hey guys i'm having some problems with my lg g3 d851, since the screen of my beloved lg g2 died after 2 years and a half, my friend gave me his lg g3 to use it as a tablet since the phone doesnt recognize any signal at all, right now is running the stock rom for android marshmallow, everything works fine except for the signal that either always keeps in "no service", i already try to put another sim card on the phone and its showing the same problem, already checked the IMEI on the swappa blacklist and everything is okay, here are a few screenshots, any thoughts on how to solve this problem would be very appreciated thank you!

hi thanks for replying, yeah i already modified the APN settings under mobile networks with the APN of my carrier that is IUSACELL (AT&T México) and is still showing the same problem "no service" or "searching"
I had the same problem, try installing another modem, or send me an pm, I have the same mobile company (right now I'm having some problems with the at&t mexico)
I am having a similar problem with my d851 30g. It isvnot rooted and running stock android 6.0 tmobile rom. I am with movistar (mexico) it will have signal and be on the network and then eject the sim saying invalid then reset. Did factory reset. Movistar sim worked for about an hour and then same thing. Have a s from telcel switched and no problem till this Morning. Did the same thing and restarted. Recognized the sim and all fine. I am new to this and could use a little help. As it is connecting with the other sim and not my movistar sim. Possible software issue or corrupted sim?
Thanks in advance,
Alex miller
