No 3G on Optimus T after rooting & custom rom - General Questions and Answers

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

[Q] No data on unlocked phones?

Anyone has managed to solve this? If I use any CM7 based rom (and even when the apn are restored after a hard boot) I cant connect to 2g/4g and in deed its not the apn issue bec if I use the stock bloated LG rom it does connect (I know in my third world country there's only 2g/3g so i can only connect thru 2g) so anyone here having an unlocked phone using CM7 and working data could share his/her wisdom with me?

[Q] Help required - Nexus S i9020

I bought this Nexus S, i9020. It's just a couple of days old. Had ICS 4.0.4 and when connected to WiFi, phone started downloading latest system update. Installed the update quickly. The battery however, started draining too quickly after the update.
My problem or nightmare started when I tried to revert or downgrade this cellphone to Gingerbread 2.3.6, because I read that on GB, this phone's battery lasted for more than a day.
Anyhow, when I downloaded this One_Step_Click guide for downgrading to GB 2.3.6, the phone actually downgraded, but to my utter surprise, it has downgraded to Sprint Nexus S 4G, the phone now shows following:
Model number: Nexus S 4G (which it's not, its Nexus S i9020)
Android version: 2.3.4
Baseband version: Unknown
Kernel version: 2.6.35.7-ge382d80
Build number: GRJ22
The phone has lost the GSM signal, although SIM is still in the SIM slot. I can still connect to WiFi and connect to my Google account.
FYI, i am using Ufone GSM network here in Karachi, Pakistan.
Need urgent help in restoring my Nexus S to its original state to be able to use on GSM network.
Appreciate your help.
Thanks.
Seems like you are actually messed up. So you want Gingerbread 2.3.6 on your NS, right?
Just confirm me one thing, is it I9020T or I9020A? I'll be easily able to help you then

Thanks for replying to my thread.
Yes, i am actually messed up.
The inside of the phone i.e. under the battery is only written i9020, nothing more nothing less.
Really appreciate your reply and help.
Thanks.
So, it is I9020T
Check your PM :good:

I am facing a similar issue (in Pakistan) and can't seem to find the right baseband/radio. I tried almost all radios at http://forum.xda-developers.com/showthread.php?t=1116884 but the problem remains - I get very very low signals (my SIM works fine on other phones). Any PM for me as well

[Q] No sim card detected

Hi, I'm new to the site and the scene and I'm having trouble which I hope someone can help me with. I got an LG Optimus One 2 weeks ago and it was work fine although it had some differculty detecting a sim card. The phone was stock 2.2.2 when I got it and I tried rooting with Z4root but that wouldn't work so I used gingerbreak then it wouldn't detect ANY sim. So I thought it might need updating in order to fix the issue so I hooked it up and used the official software and I still have the same issue. I'm not sure if it's the baseband or what but I've tried flashing v10 AND v20 basebands but it still won't work. I checked my phone status and it says the signal is negative like -100 dBm 6asu. I went to the hidden menu before and after updating and the baseband still shows as AMSS6038. I'm wondering if this is a hardware or software issue...anyone got any ideas?

[Q]ProbelamticSU 760

Good day. I've been scouring the forums for a week now and I have a fair grasp of which guides I should follow. However,I have a limited technical capability to fix it and a fair share of knowledge through reading. So if there's any of you who can pitch in some ideas,I'd gladly appreciate it.
Situation
No Wifi
On Froyo 2.2.2
Has Signal Issues
No bluetooth
Functional Phone

History
I acquired an LG SU760 phone which has been,at the time,on Gingerbread. Can't tell specifically the details but as far as I can recall,
it had a CWM recovery on it.I believe it was also rooted since I saw a SuperSU app.
Upon learning that the unit can be upgraded to ICS, I wanted it to be reverted on official stock GB,and then,later updated to official ICS thru OTA.
So I had the unit sent to a "TECH GUY" who apparently failed miserably on fixing it.Instead,leaving me with the unit with the issues above.
From what he told me,He apparently flashed or used a p920 rom,then failed. Soft bricked the thing. Downgraded it to GB. Updated it to ICS port,but got the Camera inverted and the 3 soft keys messed.Reverted back to GB with intact wifi and bluetooth. Noticed it consumed too much phone memory.And then finally settled into downgrading the thing to Froyo 2.2.2. Now I have a LG SU760 on froyo 2.2.2 with no WIFI, no BLUETOOTH, significant signal issues,no mobile internet connectivity,and a functional camera.Pretty useless if you ask me.

THOUGHTS
After reading some guides,and inputs from others,here's the issues that I thought may address the situation.
Maybe it has an IMEI problem
Maybe it was a baseband error
Maybe it had a bad flash?
So with these, I ask your help.
QUESTIONS
Priority 1:How do I upgrade it to Gingerbread and ICS?
Priority 2: How do I fix it's wifi,bluetooth,and mobile data issue?
So if you're kind enough to help a noob,then bless your soul. I work in the health sector from the Ph and being able to fix this unit might as well cut my father's losses.
Thank you for your help.

Lost 3G/4G signal, no internet

Hello guys,
Yesterday my LG G2 from T-Mobile and also wife LG G2 from T-Mobile lost que 3G/4G icon and the internet service. Yes, both phones!
The phones can call, get sms but no internet. Already perform a factory reset, hard reset, added the right APN, tryed to change the network mode, tryed with my 3 local operators and nothing, no internet or 3G/4G signal
I'll try to return the phone to stock 4.2.2 to check if this can fix the problem, currently running 4.4.2 stock.
Any other suggestion? Maybe it's just a simple fix but coulnd't find anything.
Returned to stock android 4.2.2, using this guide: http://forum.xda-developers.com/showthread.php?t=2432476, by the Tot method and it's working again, updated to 4.4.2 via OTA and everything seems fine now :good:
