[q] g2x no tmobile connection or battery data

Ok I am in dire need of help! I just flashed my G2x and have no connection to tmob ile whatsoever. Ive tried three different roms no including eagles blood, hell fire phoenix and now bionix. each time ive got no tmobile connection and no battery data also. dont know if ive done something wrong any help?

Have you tried CM7? Did you do a full wipe prior to installing? Have you tried to flash back to stock? We need a little more info, please.

yes ive tried cm7. i just recently reverted completely back to stock and still no connection or battery data. when i originally flashed rom yes i did full wipe cache wipe and dalvik wipe. well when i had flashed clockwork mod recovery i did it through rom manager and my first custom rom flash resulted in a boot loop and i wasnt able to get back into recovery.. after hours of searching i figured out how to flash recovery through apx and was able to get into clockwork recovery and there i flashed my rom.. since then ive tried everything to get a connection to the network with no success. even reverting to full stock.. now before it was stock gingerbread and now its back to froyo.. have tried over and over to use lg update tool with no success.. thanks for all and any help

So im still searching.. With no luck.. Turns out it is a baseband problem says unknown.. Im literally seconds from throwing this phone at the wall!! Aaagh...

If you have no baseband, you may not have a radio installed... no radio/unknown = no data. Try flashing your desired ROM and then flashing a radio. I don't much about the G2X... you might want to check this thread out: http://forum.xda-developers.com/showthread.php?t=1332350
Also, I just read that you can go to LG's website and use their official updater. Some users have said they had to return to stock to get it to work, while another claims they had CWM Recovery and CM installed and it worked perfectly. Bottom line is that is sounds like you need a radio.

Yea ez stuff. Downlosd radio and flash it

[Q] Soft bricked? Qualcomm radio is messed up

First off Im new here. Well I haven't posted on xda before, but I've spent enough time reading.... anyway, have an vzsgs3 cwmr bootldr unlocked flashed taste of beans... then wiped flashed slimrom and then nandroid'D stock over that.got the wonderful nonvzw triangle of death.... after that I flashed stock root66 via Odin. Lost my imei in that whole process. Didn't have it backed up either.went through pretty much every post that related to the sgs 3 and imei.Now I have a 4g ONLY device.I also found out that you cannot make or receive calls on 4g and the tower negotiation/propagation takes place over the cdma network. If I restart my phone every time I move to a different tower I can use it on 4g to surf the web. No call or texts ever. If I leave the range of a tower, I get a /0 slash zero for reception. Reboot and 4g is back.This is strictly 4g ONLY.it will not and cannot connect to the mobile network .try to dial out, error: mobile network not available. Factory reset several times. Phone is back to oob stock. I would be tempted to say there is something mucked up in the nv rf items. By flashing and resetting, it would set everything back to stock except the radio FW. Switched Sims with a working one... same. Imei is fixed, about status shows it correct as well as the correct phone number and everything else. Where should I go from here.? Let me know what info u need and ill post it.thx!

Nobody? I can't use my phone, somebody has to know somthing bout it? I've spent hours googleing and searching the forums... no luck, it would be helpful if somebody could post something that might lead me in the right direction... ANY help is greatly appreciated!

No one is gonna reply because you suck at writing stuff out and cant understand what you are saying.
As for your phone, the imei has been restored but the phone is still borked? Did you odin back to stock after all those issues? That would have reflashed your modem. Did you check the md5 on the crap you flashed too?

I would odin back to stock if that doesn't work. Try to instal one of these basebands from the link. I'm pretty sure flashing stock with odin does thatthough. I'm a noob but that is my best guess. Good luck.

There is a tool on here that you can fix your IMEI with, if you haven't already. I would try to reprovision the SIM if you have done everything else.

[Q] [CM10 ROM] No GSM, baseband coming up as "unknown"

Hi,
after being a lurker I finally made an account to ask for help with a problem I can't solve.
I flashed my P500 with the latest 7th build of the CM10 by Rashed97 from stock 2.2.2 with V10a badeband.
All wipes done etc. flash went well.
Only problem, the phone didn't detect any SIM cards, detected no GSM.
I went on looking at all the ways to flash baseband and fix it. In the end I failed, tried LGMDP got errors, tried the fix provided by some of the users but the baseband stays "unknown" (not sure if was like that b4 fix, so I recovered to 2.2.2 and gonna do it again).
I'm asking for some advice, just how am I supposed to handle it this time so in the end I get a functioning phone.
Should i update baseband first, then flash ROM?
Cheers, looking forward to your replies.

First link in my signature below. Try flashing that.
If didnt work, unzip it and place it in /system/lib and set permissions right.
Same as other lib's permissions.

I used the fix already, didn't work. Tho i didn't figure out how to get it into /system/lib (where do I find that directory?). You mentioned in an earlier post, that one has to use root explorer, as in an APP?
Or maybe I'm supposed to flash the fix while I'm still on stock 2.2.2?
EDIT: Ugh, I'm tired and my posts are quite bad, but I got some news.
Baseband turns to unknown right after flashing ROM (flashed gapps also). So I'm gonna try that method of yours with putting the fix into /system/lib , I'm off to figure out how it's done....
EDIT2: Copied and overwrote the files from system/lib but where do the META - INF folder go?

Meta-Info folders are for recoveries not for us
No need to extract them.
Sent from my LG-P500 using xda premium

Sadly, even extracting the fix and putting the files manually into system/lib doesn't fix my problem ( I even checked the permissions).
Maybe I should just try updating the baseband first on 2.2.2 and then flash the CM10 ROM?

So I updated my ROM and baseband with G Mobile Support Tool.
Right now I got stock 2.3.3 with V20c on my P500. I guess I'll make a recovery of this and start flashing the CM10 again.
EDIT: Now this is bat**** crazy. After getting stock 2.3.3 had to fight to root it (finally managed with Onec Click Root). Now when I got my superuser I can't even go into recovery. Holding home + vol up + power makes a factory reset instead (superuser stays, other app like rom manager, quickboot and settings get deleted). So wth?
I think I'll try reflashing recovery with rom manager (after i once again dl it).

Victory!​
:laugh:
Finally I managed to get it to work.
After updating to stock 2.3.3 I already had the right baseband, so then I just had to reflash recovery (which fixed the issue of going into recovery mode) and finally reflash the whole CM10 ROM.
Got greeted by phone asking for PIN, GSM works with full bars and now I can sit back and enjoy the smoothness of JB Android.
I'd like to thank all the people who answered my posts, gave me advice and tried to help.
I really, really needed this :victory: because changing to P500 with 4.1.2 is a really great upgrade from my GT540.
That's both for soft and hardware (finally multi-touch, Donkey Kong Adventure on SNESOID, here I come).
Rock on guys! :highfive:

The Lg LU6200 is a much different phone from ours and probably has a much different solution to your problem, I would recommend you ask on the forum for that phone. The nitro HD is a very similar phone, and there is a development subforum for your phone in the nitro hd's forum so there is probably a solution somewhere on there: http://forum.xda-developers.com/forumdisplay.php?f=1445

You can search the forum mentioned in the previous post or this thread as I think it may be more along the lines of the answer you're looking for. Since I don't have one of these devices, all I can do is search and hopefully point you in the right direction.

Help Pls, I think I've just Bricked my phone :(

I've installed the new CM10 on my P500, It's working just fine, the problem is I have no GSM reception, it doesn't detect my sim card. When I upgraded from my GingerBread Void version, I wiped the system clean, and I do believe (knowing what I know know) that I've erased everything, including my baseband.
I've been looking into the problem and it seems that I should have kept the base-band (or something).
I've downloaded the LGMDP and the V20 Baseband in order to try to rewrite it. But no dice. After I hit download the End window shows nothing but the IMEI, no Bluetooth ADDR, nothing, just the IMEI.
Also no NV2 file is generated.
Does anyone have a clue?

Does it boot but not ask for the PIN to unlock the SIM?
Sent from my LG-P500 using xda app-developers app

Yes, it boots just fine. The CM10 works brilliantly ), smooth and clean, but I have no GSM, it simply doesn't detect my SIM. If I try to make a call it says something like "no network detected"

In the "about phone" menu, the baseband reads "Unknown"

Ok, I've been reading some more and It would seem that the phone is not literally "Bricked". I think I have to flash a stock rom back in order to get the right baseband. Please correct me if I am wrong because this is what I am going to do when I get home, being that I'm at work right now I have no way of testing anything.

Well if it boots, you haven't got a high-tech brick. I had a similar problem recently although I didn't check in any of the menus like you said. I knew when it didn't ask for the pin. For some reason it wasn't detecting the STK.apk although it was there.
Have you got some kind of file explorer (root enabled) installed? If so, check /system/app to see if STK is there. If not then you need to put it there (get it from another ROM). And edit the permissions to RW-R--R--.
As it was there for me, I tapped it so it installed (as a user app) and then uninstalled it and rebooted and it was fine. I guess it just needed reminding that it is, first and foremost, a telephone.
Formatting everything through recovery shouldn't wipe your baseband but if you still get nothing there are tuts here about flashing BB.
Hope you get it solved.
Sent from my LG-P500 using xda app-developers app

Hmm, thank you, I'll be sure to check that.

If you were on Void before you transitioned to cm10, most probably you may just have to flash an "old BB fix" ( available in many threads in this forum, just search) as Void was for old BB & all the current new ROMS including CM10 are on new BB. Avoid new BB flashing thru LGMDP or any other means as far as possible. old BB fix can be used without any side effects on CM 9/10 based ROMS.

If your using AmonRa recovery you have to mount system before you flash obb fix or it wont work.

At the moment I'm using Team Win recovery, but I'll definitely give that a try

Not at the moment, I've finally gotten home, I'm working on it right now )

Brilliant, I've got it working, I'd like to thank all of you, especially WidowCranky and 3ncrypt3d_Droid who gave me the right clues . The permission wasn't set on my TeamWin recovery and the BBFix Update wouldn't work. Set the permission right, flashed the fix. Works perfectly. Thank you all very much. I am officially on Jelly Bean

Congrats & enjoy.

There is another work around for that issue also, just to keep from having to apply the baseband patch after flashing ROMs. Instead of flashing P500 ROMs, flash P509 ROMs instead. The hardware is identical, only difference is baseband. P509 will always be old baseband as they never got official GB support from LG. Just a thought. That's assuming the dev for the ROM you are using builds for P509 too. Again, just a thought.

Glad you got it working, glad I could help, even if only in a small way.
Enjoy JB.

Hi, trying to USE the app GSII_repair from the android store.
Phone phone seems to be having the "no sim card" error come and go, I think there is some weird problem with the radios, pulling my hair out.
No the app i got, that might fix it says you don't have .nv_data.bak and his md5 files, canceled
I wonder if this helps figure this out ?
Thanks anyone ! would love someone that could help me a bit here.

Your efs may be hosed which wouldn't be good. That's above my grade level. See if cschmitt can help. He's your only hope of it is a hosed efs.
EDIT, I just looked at that app, and sorry dude, but I think you hosed your phone. It messes with the partitions and is not for the i727.

What does your baseband say in settings, about phone? Also, check your apn settings.

try icenight's fix

read and try this.
I used that app before and got the same thing. I odin'd back to stock GB at the time. Flashed a gb radio (Ics leak just came out) That worked for me.
However this should fix your problem.

1727RUXLF3
when i try to go to the "moble networks" menu,and click the apns, there is none, when i try to ad my apn settings, after i fill everything and out and hit save, it is blank under apns.

If I were you I would start from scratch and Odin the newest official release of at&t or Rogers depending on what carrier you're on. Did you reflash the radio?

Thanks for the help so far...
So here is where i am at now..
Have flashed Slim Bean, and various radios, I had the factory firmware on there for a while, it up and running, I have and IMEI number, my sim card it being picked up as it says rogers, but it says "no service".. it's weird because in the APN settings, it gets the settings from the network, they are there (rogers LTE) so it must be connecting somehow right ?
I have tried searching for available networks, nothing comes up, it's like my attennas are off or broken.
Is there any way to force my phone to see if has any antenna working or something ?
Thanks guys for the help, your the best, but I might need a new phone.
