Hi! I'm not new to android modding, but with this phone (the 3D) I founded some difficult. There is some confusion in my mind about the baseband,ROM etc... Now I run CM7.2 with baseband v21d, but before I try to install CM10,but I encounter some problem:
1) My phone, like happened to others users, works properly without SIM, but when I put it inside the phone, and then PowerOn the device, it stuck after about 30 sec and then reboot.
2) I bricked my P920 trying to come back to GB stock (there are too many guides about it,and maybe I forgot something...). However, now my P920 is like new because I havd warranty and my store repaired it.
The question now is this:
I install CM10 on baseband v21e and v21d...but the result was the same: reboot with SIM.
What can I do to have CM10 on my wonderful P920? thx for the attention :good:

Download the latest nightly and gapps. (There are links everywhere.)
Flash v28 baseband (There are links everywhere.)
Flash your CM10 rom.
Flash Gapps.
You're good to go.
No SIM problems here.
No problem with V21D and V21E here. *knocks on wood* However, I recommend flashing wpark's v1.25a bootloader (or BIOS - same thing) as it forces any modem firmware to stand up - V21D as a minimum - just go with V28A if you want the fast way out of SIM issues on original bootloader (or wpark's).

so...if I install wkpark's bootloader on v21d,and then CM10+gapps it should run with SIM? tomorrow i Try (in my country,Italy,it's half past one :silly: ) thx for the reply
You can try V28 first and see.

Ok...so the plan is to flash the v28.kdz and then install cm10 right?
now I'm on CM7...if I flash v28.kdz it's right? sorry for my ask...but bricking this phone make me careful!
You can install cm10,gapps and wkpark's bootloader now. That's the easiest way now. Besides that thing is actually nearly unbrickable there is a good chance you could have repaired it by yourself. But let's not talk about the past. Try, it should work.

ok guys...I don't know how to say but... IT WORKED
I wiped cm7.2,and I install CM10+gapps. then I go into fastboot mode, I flashed manually u-boot+x-loader by wpark and then...it doesn't freeze! I really love you guys...really...now I have a badass phone with cm10...

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

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.

thank you, but i have no luck, few user of LG LU6200... bad luck..
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.

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.

Today I decided to root my phone, and did so with z4root. Then I installed a rom, using ClockWorkMode recovery, and crystal rom cm10 Jelly Bean. Everything works fine, except I get no cover/connection at all. From what I gathered by googling all day I probably didn't upgrade my old baseband to a new one, thus causing all of this. I get a null IMEI.
The version on my LG P500 was 2.2. I didn't make no backup whatsoever (I know, I know...).
Can I revert all the stuff I did today, returning to a factory state? Or any way to solve this mess?

Don't do what the person above says, it will brick your phone and you will not be able to use your phone at all. Download lgmdp and flash v20g baseband through it (for files and tutorial search Google), do not interrupt the process. After it has finished, restart your phone and your network signal will come back.

Mr. Junior Einstein, read the whole post before you say anything. Stop provoking me to take any step against you.
I already posted a link for lgmdp thread for the convenience of user.
Thank you.
Unfortunately the computer won't recognize my phone when I connect it, if I don't switch mass storage on. Can I follow that procedure anyway? Otherwise how do I fix it?
Thanks.
KDZ should be the absolute last option you try, only if all else has failed and you r ready to accept a chance of a brick . Instead You can just flash the old bb fix http://forum.xda-developers.com/showthread.php?p=39893089. This works for all roms ( makes them compatible with phones whose base band has not been upgraded). Enter recovery, flash rom, reboot then flash old bb fix then reboot. Works flawlessly. You have to flash this after every new rom you try and you can be on old bb for ever. No worries. Hope this helps.

KDZ will not brick your phone. If anything, LGMDP is just as likely to brick your phone. It is all about what you do or do not do, as in: do be careful, and do not interrupt the process until it says complete. This is true for BOTH programs.
I've used KDZ more than 20 times and not once have I bricked my phone.
I was able to fix using the old baseband fix here.
Thank you very much for your help!

Both have near equal chances of bricking / not bricking. All depends on how much you understand what each tool does, how it works & and what precautions you take.

ager, and then I just added the rom file to my sd card. Then I pushed the buttons (3D+power+vokune down). I cliclicked the install zip on sd card and i choose the zip file. Then I saw a android logo and i think it was installing. It then reboots and i see the lg logo, but then i see a black screen.
Can somebody help me. Sorry for the bad english
Each rom has a wsy how to be installed. It is always written on the first page. There is written also on which base you shoukd be and all requirements that your phone should have before yiu start to install custom roms.

do you have ICS or GB as a main base? which one 1A, 21E, 21F, 28B, 30A... etc.
what kind of rom you try to install GB or ICS?
Have you open the boot loader.
Read always the first page of the threat if you want to install any rom. Follow the steps inside them, no the steps of a programs that do that.
