[Q] help i dont know if my phone bricked?

I bought a g2x from craigslist. its brand new but i guess that previous owner has done some update or something now it does not show any baseband version. So my Sim card which i changed to 4g version yesterday does not show any network. my old sim card did not show any network either.
this is what i see when i look at About Phone
Model # LG-P999
Android Version 2.2.2
Baseband Version : Unknown
Kernel Version : 2.6.32.9
Build Number : FRG83G
Software Version : LG-P999-V10f
I am coming from a vibrant with using bionix and not new to rooting or flashing rom. I did research a lot. But not sure if this is something that can be fix.
Please help.
thanks a lot in advance

Try the official update ota or via LG, other threads describe the process and that might get you the new baseband.

I tried to run the software update check from the phone. i connected with wifi. but i guess as it does not have a connection with tmobile netowrk its showing connection failed.

I think what heysharon is saying, is to update through lg website with your phone connected to your pc.

Ohhh, Yeah tried that already. But LG updater says device not supported for update. is there a way to flash the baseband ? I have a feeling that the previous owner flashed a o2x rom or something which changed the baseband. and then he ran the recovery to fix it.

Which model do you have? Check under the battery hood if it's Model 990 or 999. Perhaps it's wrong update for the phone.

Sorry I saw now you said it's 999. If there is no baseband you might have to return it to the Tmo...

Was it working when you bought it from the Craigslist seller? Did you try it with a SIM card before you bought it? Just wondering if the problem was there when you bought it or if you might've done something to the phone after you bought it.

it was working with his sim. my sim did not support 4g network at that moment so could not check it with my sim. then i got my sim yesterday. and have been trying to use it after words. no Luck. i guess i just lost $300.

That seems odd. You saw it working with his SIM? Did you or him make any changes to the phone software after you saw it working? The baseband wouldnt just disappear.

Probably didn't flash an O2X rom as that would've changed the partition table and I don't think you can restore the G2X system back to it ... well at least without going to great lengths to fix the partitions.

i guess what happened is i really did not check it throughly. his sim was inside the phone and when he gave me he took it off and did a factory reset. thats what it was. and i was texting him before we met and he was calling me or texting me from his phone. i believed him. and i can see what happned for believing him. great

Try doing the regular nvflash thing root it n flash a rom or stock nanroid maybe that'll bring the baseband back

S3 - Not registed on Network after Jelly Bean Flash

I'm getting a Not Registered On Network error on my phone since I tried the official Jelly Bean update.
The IMEI seems to ave changed too and I've a serial number of 00000000
I had a look at other threads but this only happen after I did the flash - I've tried going back to stock but it seems to be there too

Theres an official jellybean update for this device? *headscratch*
I'm going to assume you flashed the update for the international variant on your d2vzw. Odin back to stock.

In the dev section there is a tutorial on how to backup and restore your IMEI. I still *knock on wood* haven't run into that issue yet.

Did you properly backup your IMEI as described in several threads in the development section? If so, restoring your IMEI is simple.

No, there are several unofficial Jellybean roms for our phone. They are based on the T-Mobile leak from a while back. We're a ways away from an official jellybean OTA. The OP wouldn't be able to boot their phone and discover their IMEI changed/phone number reset had they flashed an international rom.

Sadly you flashed an international rom. Sorry. I thought this would be a hard brick. But since you can boot you can odin back to stock.

Its not a hard brick since he is able to boot up, but beyond that IDK. OP, when you said you tried stock and still no go, did you mean that you used Odin to flash a stock image? If not, that is your best bet.

As long as you can odin back to stock and you have a Verizon device, there is a tool in the dev sections stickies that can restore your IMEI even without a backup.

Now that u r back to stock do a search for IMEI restore on xda to restore your phone.
For future reference note that there are several GS3 variants and u can only flash the one specific to your carrier if u want to have a functional device. The international version doesn't even have the same processor.

You are correct, but I think you mean more accurate not precise

THanks for all the pointers - I'm a bit confused though and possibly I haven't given enough info...
The S3 was originally running on AP i9300xxalef CP i9300xxlef CSC 19300OJVALEC and it was rooted - I'm in Ireland so it appears to be an international phone.
I can't get a product code because when I try it gives me NOt Registered On Network
Previously when ever I tried to update it via Keis I never could and it always showed the serial as 000000000 I also think the IMEI as different.
I did try to flash it previously and it failed I but it kept working - So I wonder could the IMEI switch have come from that - as I do seem to remember the 000000000 from before I tried Jelly Bean.
If I put it back on the same AP CP and CSC would it work again - and how would I go about it?
Thnaks

Brought it back to the original firmware - and getting a no signal icon now!

I don't know of any tool for the international model's Exynos that is like the tool for the Qualcomm processor.
Everything I've seen, says in order to restore it on the Exynos processor, you need to have backed up your EFS folder. There are a couple threads in the International GS2 forum (not the GS3 forum) detailing how to repair it, but that entails you having have backed up your EFS folder.
Not sure if there is a way to fix the problem if you are able to get the IMEI number from your box or behind the battery.
Edit: I just did some googling and found there is some kind of Samsung tool for repairing it. There are a couple youtube videos that I found as well. Some tec site is claiming that once you restore to stock, you get a new EFS folder on your phone and although the information will be incorrect inside of it, you may be able to edit it. :shrug: You would have better luck in the international forums though if you have an international phone.

Read this on another forum regarding this issue for MIUI for the Verizon GS3:
"In CDMA subscription, NV was selected, so I clicked UIM and gave it a reboot.and I had data. So decided to flash miui again right now and NV was selected again. UIM and reboot.and I have data."
Perhaps this is your issue as well. No harm in checking, I guess.

MIUI and the horror stories. I hope you get it squared away.

[Q] No SIM or wifi after factory reset

Hi,
Yesterday, I had an update from 4.1.1. to 4.1.2. I'm running the stock rom. After I ran in the update, I re-rooted using CF-Auto Root.
Today, I thought I'd do a factory reset. Now, my phone won't detect any SIM card (I've tried 2) and although it seems to detect my wifi, it won't connect.
I had the phone on airplane mode when I selected the factory reset, but I wouldn't have thought that would matter.
Interestingly, I can now select airplane mode to turn on, but it then ghosts out and I can't turn it off.
I have a Samsung Galaxy Note 2. Please help!

I'm inclined to think this is a software problem as both sim and wifi worked perfectly before the factory reset.
I've tried registering with SamMobile to download the stock rom, but their registration page seems to be wonky. It complains I haven't completed the anti-spam task, but this area of the form is just blank.

yep.. thats a loophole in google... try doing it again... this time with cwm.. if that doesnt work.. u have to get the stock rom via odin

I just flashed the exact modem I had before, and my baseband, imei etc. are all coming up unknown.
When I enter *#1234#, my cp number is also unknown.
Do roms also include modems? I was once told they didn't. Sorry, I've never flashed anything before besides when I was getting root access

Thanks for all the replies.
One further question, then I'll go hunting ....
I have the GT-N7105T. I know the T variant has different radios. Some people say you can use N7105 roms and some people say no.
Can I safely use an N7105 rom on my N7105T? The phone is pretty useless at the moment but I'd rather not brick it.

There's your problem!
The difference between the regular Galaxy model and the T variant is the modem. Telstra 'tweak' it on a hardware level for their NextG network and it means that the performance of the modem is affected to varying degrees (severe in your case) if you use a non 'T' modem.
There should be a modems thread, there should be a N7105T modem. I'll have a look and post back if I find one.

BOOM!
TDVDMB1 (Australia / Telstra) N7105TDVDMB2
TDVALK4 (Australia / Telstra) N7105TDVALK3
Either of these should work, keep them to flash after you reflash a rom onto your phone

good for u.. u got an australian to help u out..

I've tried flashing the modem but unfortunately it had no effect.
I don't have the phone on me so I can't confirm this, but I'm starting to have scary thoughts about the efs. Unfortunately the only changes I've ever made to my Androids was just to root, and I didn't even know what the efs was.
Thing is, after my update my phone worked fine for over 24 hours before I reset it. Does this sound like the efs? How can I tell if that's the problem?
I guess I had to learn somehow, and I've definitely learnt ...

Would it be possible for me to get a copy of an efs folder from another Note 2 and adapt it to mine?

For anyone else who may come across this, I solved the problem by downloading the stock ROM from sammobile and flashing that.
I have also now flashed TWRP and have taken a nandroid including the EFS.
We all have to start somewhere, but hopefully my bad experience will prevent someone else's.

[Q] Problem with nework

Hi everyone!
I flashed my i9103(Galaxy R) from 2.3.4 to 4.0.4 Stock India via Odin, and after that my serial number has become 000000000 and the phone cant find the network!
I tried flash another 4.0.4 stock rom, but nothing has changed. IMEI is OK, ONLY with serial number problem
Sory for my bad english
I will be very glad for advice! Thank you!

Yes, it is. You don't post in a forum for a completely different device purely because nobody posts to the forums for your device. Mods will be moving your thread to where it belongs.
