No 3G on Optimus T after rooting & custom rom

Hi,
I have an LG Optimus T with T-Mobile (G509), and network data (3G/E) used to work just fine. I've unlocked the phone, rooted it using z4root, then flashed the DarkMoon rom (2.2.1, G500, based on V10c). Since that point I've lost the 3G or even Edge network data. I can only connect to the internet via Wifi. I can't even get GPS location on Maps if the Wifi is off.
Any clues? (I'm still new to Android).
Thanks a million in advance!

As I told u in a private email., I will send u a file to fix this problem, and in my next rom upgrade things will be fixed

Will this ROM work on the Optimus for Sprint??

the same thing happened to me. Can i have the file to fix this to?

I also am having the same issue with my phone. After rooting it worked fine for a couple of weeks but now I am unable to use 3G. I am only able to use data when connecting using wifi. Can you send me the file as well? I would really appreciate it. Here are my phone specs below:
LG Optimus V
Android Version 2.2.1
Baseband Version VM670ZV4_60401001
Software Version VM670ZV4
Hardware Version 1.2

moto g xt1031 mobile network and wifi not working

Try to flash another ROM and see whether it works ,mine is also xt1031 and I have never got this problem ,I flashed a lot of ROMs

Lost LTE after the MM.zip update

Need some help, tried to run the radiozip and still do not have my LTE bands. I am running 6045O Cricket Varient. Tried different roms flashing the zip with a 5.02 rom. Still no luck and no change with the lte radio signal.
I am doing something wrong?
Thank You in advance you guys are great on here.

use Alcatel mobile upgrade Q 5.0.6 PC app to return to stock with all partitions and it will work. But you have to keep in mind, that (if it is avaliable for your model) the mobile upgrade q will flash the latest firmware, which should be MM.

Hello thank your for your reply. I did try this but I am getting the error No available device is detected. Please check the COM port status.
Any Ideas?
Thank You

install drivers from the app folder, reboot computer, turn the device off, run the mobile upgrade app hit start, connect device

What are my options if I've used the Q upgrade 10+ times and still only have 4G HSPA. I tried flashing famewolf's backup radio and my own, to no avail.
Cricket 60450
edit: This is the second time I lost LTE. To recover LTE the first time i had to flash Mobile Q three times. That was about three weeks back. I made a backup of that radio with the save2sd script by famewolf and that also does not work.

If your doing using lg flash tool or Referbish flash in LGUP and performed a factory rest from recovery and still have an issue it most definitely sounds like a hardware issue.
Have you tried connecting to a open wifi network or a different wifi network??

I tried 8 wifi network, everytime phone says wifi saved. If it is about hardware, how can i fix this? My phone doesnt have warranty. I buyed this phone in usa and i guess this phone doesnt have a repair service in turkey.
And my phone's imei number is clone, can problem be about this?

If it's hardware you can't unless you take it somewhere to be repaired. You cannot fix hardware without taking apart the device and or replacing a part. If your imei is not original that has nothing to do with WiFi only cellular.

It's a hardware problem. Only fix is usually a board replacement. It's a common problem

Its not a hardware problem because i am facing same problem but my hardware is correct and i started to face this problem after marshmallow update

Problem Solved
I have solved my problem.
This problem arrises due to installing custom rom and restoring qcn and it could not be solved by restoring back to stock etc.
Simple solution to that problem is
First you need to install any Marshmallow firmware custom rom fulmics etc.
Then go to hidden menu
1- on dial pad : *#546368#*850# (850 is for D850 and write for your model )
2- find and click SCV Menu it should be 3rd one
3-click on CRCWIZARD Test
4-click the tab Auto MID
5- uncheck IMEI in MID settings
6- click generate to generate your new MAC's
7- click MID write
8-Click Refresh to be sure that you changed MAC adress
9-Rebbot phone to take effect!
After reboot you will be able to connect any wifi without having wifi saved problem or connection failure

Sprint S5 (g900p) MM 6.0.1 QA2 stock odex, native hotspot issue

Hey!
i have problem with my hotspot...
Flashed with odin last PL2 and OTA to QA2, rooted and unlocked hotspot with idones.apk 3.1.8.
Now, "Hotspot" in settings menu. I can activate hotspot, but cant to connect with another device. Stuck on "Obtaining IP adress". If i connect with static IP, doesnt work internet and any data for share. Hotspot icon disappears from notification panel.
pls help anyone... i have tried to edit services.jar and apns to "dun".

if hotspot is something you use a lot, install @tdunham 's ROM and you will never look back! It's PK1, but it doesn't really matter much. I have been more than happy with that rom.

Thanks... I have used that ROM. Hotspot didn`t work. @tdunham said that hotspot works only on sprint carrier. I am using my phone in Central Asia on another carrier. Is there anyone uses hotspot with another carrier?
P.S. on lollipop i could unlock hotspot with idonesapp, but not work on marshmallow.

Yea, I use virgin mobile (subsidiary of sprint) when i am in USA, but I also use the same phone (G900p) in Europe with Vodafone (using it right now). I did a clean flash of his rom, and hotspot works just fine with vodafone. I can also go to More Networks->mobile networks->access point names, and I am able to add/modify my own APNs (I am also able to modify apn by typing ##3282#->view, just like I used to do it in lollipop).
