[Q] Samsung Galaxy S won't connect to network

I have an SGS that won't connect to my service provider network. It doesn't show the imei number when I dial *#06# and when you type in in *#1234# it shows the following details
PDA - i9000xwjs3
csc - i9000xfvjs1
Phone - Unknown
I have tried flashing it and installing new ROMS but the problem persists.
Right now I am using MIUI ROM.
Any Solutions?

You need to flash another base trough odin... try gingerbread jvp...or even better ..CM7

This sounds really dumb but where do you I find these bases, so far the only popular one is ezbase which is what I have already used.

This loss of imei is well known with miui, go over to their thread to find solution, to get onto miui you must have gone via cm7 surely
Insanity cm017/glitch v10c

I will go through the thread, thanks for the advise, also noticed in the efs/imei folder the only file in there is the bt.txt which has the mac address of the phone.

Phone crashed tried to fix it, now no signal

Hi guys!
I'm a little new to all this Android stuff and tried to learn how to fix my phone but I've been reading around in circles now for two days and still can't make heads or tails out of it.
I've got a LG P920 Optimus 3D that has stopped working.
Now what happened is it froze like a it had before and didn't want to shut down when I held the power button so I took out the battery. When I turned it back on it got stuck at the LG logo right after the LG sound played.
I tried some sort of LG update but that didn't work then I tried a couple of things I found on different forums something to do with the LGflasing tool or something witch also didn't work (or at least I don't know what I'm doing) and at the end I was able to hold some vol+3d+power and got a recovery menu and wiped everything I could find.
Now the phone turns on fine and everything works except for the phone part. I don't get asked for a PIN and it just says "no network" with any SIM card.
Here's the data from my phone:
Country of purchise: Slovenia
Android v: 2.2.2
baseband v: L6260_modem_sic_01.1042.00
Kernel: 2.6.25.7
SW v: LGP920-V10K-SEP-17-2011
Can someone pleas help me and explain what I'd have to do to get this thing working again because currently I'm out of ideas and I have no idea where to start.
Can I do something on the phone to make it work or do I need to flash something and if so what and how. I'm really lost here and can't seem to make heads or tails out of all this.
Thank you for your help, patience and I apologize in advance for my lack of knowledge in this area.

I punched in *#06# and it just outputs IMEI and blank. I'm guessing there should be a number outputted. What would this mean?

You wont connect to network till you get IMEI back. This is baseband problem. Check your PM i will send you instructions what to flash and how to restore IMEI.

Yes success!
I was able to use the method in the link above to put a newer rom on the device and it seems to be working fine.
Thank you very much guys. This is all very new to me. I hope it doesn't crash again since I was scared that I lost all of my contacts but thankfully I had a backup.
Best regards

having the same issues
Please help. can you send me the instructions also iodak to this issue.

Here you go. Works 100%. And you will get the new gingerbread baseband.

Think you could send them to me as well? I too deleted the IMEI and the process found here dont work, the sofware tutty doesnt respond and cant flash with KDZ because the sofware fails, thanks in advance

Use this:

You cant write IMEI with hyper terminal until your IMEI is that strange number. If you cant get it that way with smartflash tool (erase CP). Flash lg prada baseband that will do same thing. After that flash 21e baseband and restore imei with hyperterminal.
Edit: check if you got drivers instaled.

Wifi not working at all.

Hi all!
I have a problem with my LG Optimus 3D. I cannot enable the Wifi, when I tap on the wifi enable icon or try to enable in the Settings it just flashes. A note, I forgot to disable the wifi when I went to sleep, and my phone was on wifi all night, but I think this cannot be the source of the problem.
Here's what I tried so far:
- Hard reset - Wifi not working
- Factory reset - Wifi not working
- Changed the ROM - Wifi still not working (I used this ROM)
Any suggestions ?
Thanks for the answers in advance!

If the wifi is not working in any situation consider to put it back to stock, clean it up and give it to assistance to repair it.Might be a faulty WiFi module. Are you sure that you don't use a fixed IP on the phone or your router is faulty?Just asking...

Hi!
Thanks for your answer! My router is working fine, I cannot even turn on the Wifi on the phone. :/
Any more suggestions ?

Well the return to stock and assistance is still valid.Try doing an emergency recovery using update tool from LG.Maybe the new version software- the 2.3.7 version with v21e baseband version, would do something good. Cheers mate and good luck.

This is certainly not the source of the problem. I keep my WiFi always on (from advanced settings, WiFi Sleep policy: Never) which doesn't consume much batter when the phone is on standby.

did the problem occur when you flash the rom ?
in which baseband you had
for example if it was 2.2 baseband and the rom was for 2.3 it can not be flashed with clockworkmod
you should flash the kdz files for 2.3 baseband and then flash a rom with clcokworkmod
i also had problems with wifi and i did flash a 2,2 baseband ( kdz files ) and the problem was fixed

Can someone help me? I got a wifi issue also.... sometime i can't turn it on... and it drains my battery so quickly... and whenever it happens, i have to restart it in order to use the wifi... i think i have a stock rom... i don't flash another rom again since the last rom from thaiz... and there're not a big improve at all...

I had WiFi issues (and signal issues) from wrong base bands in GB. Some ROMs and kernels aren't compatible with certain base bands and you can either lose WiFi, signal or both

Flash back again to GB or find the right baseband for your country and i think it should work. Good luck

I also have problem with cm10 on o3d p920. First I installed on v21a baseband, mobile network was working but the phone was switching off all the time, sometime after short period of time and sometime after longer period of time. After that I change baseband to v21d, because in cm10 thread was written that it works only on v21d and installed cm10 and mobile network didn't work at all. Any solution? Somebody?

I am having the same problem, using it on AT&T network and it will not find the network. Hopefully a solution to the problem will be found.
