Thanks for the guide, everything worked and I'm on new baseband now,

The only problem I had was that the phone booted to my rom during the flashing and the application was trying to communicate and just stuck there, I left it a bit and restarted to recovery and it finished everything.

P-509 Old Baseband (v10S)

I've noticed that no one on these forums has ever posted the old baseband for us Optimus-T users who applied the new baseband but want to revert to the old baseband given that the old baseband fix is available (http://xdaforums.com/showpost.php?p=35924286&postcount=2). I finally got around to doing extracting the old baseband files myself (with DZDecrypt) from the v10S KDZ and packaged them with the tool from this thread. This means that a full restore with the stock Froyo ROM is no longer necessary to get the old baseband. Just run the tool in my .zip as you would the tool in the original post to return to the old baseband and flash the old baseband fix to get compatibility with new baseband ROMS.

Will an admin or the OP please place my attachment in the original post so that us Optimus-T users no longer have to go the longer and more dangerous route of a full restore to get the old baseband? Attached is a screenshot of my phone with the old baseband running the Oxygen Gingerbread ROM.

Thanks!

lg optimus G radio not working properly

i own an lg optimus G e970 at & t version on ics

i rooted it.... installed slick JB on it http://xdaforums.com/showthread.php?t=2084431

but forgot to install the modem via recovery.... so when i turned my fone ON, i had carrier network signals available but wifi was not working....

i downloaded a KOREAN kdz for f180L and tried flashing it on my e970 via R n D tool...it was successfull but when my fone rebooted, it was country locked (required some password at the beggining)

so then i started looking for the other kdz,s available online (as i was specifically looking for kdz for at & t LGOG)

then i found a brazilian kdz for e977 and flashed it to my fone via R n D tool and my fone booted up.....everything working but no network signal showing a sim error icon in status bar

edit 1: finally i got the LGNPST to work and flashed the stock at & t rom but still it shows "no sim card"

flashed a different jb radio...its getting weak signals

working on it now

may be need efs

[Optimus One, P500, V General] ibub:
How badly is it bricked? No signal, but OS running? Your NV2 backup should be 179kb. If lgmdp timed out, chances are that it lost connection to your phone. Try this: start program, turn off phone, pull out battery, access emergency mode by simultaneously holding back button, volume up, and while holding these buttons connect to computer (not easy to do, but this causes phone to be recognized). When program recognizes phone, select nv restore. After only a few minutes, program should finish.

sent from the p509 that I thought I killed again... no trouble at all :cool:

I'm trying to use LGMDP but it never recognizes my phone.

I installed the drivers (a second time to make sure, I already had it once to install cyanogenmod), I enabled usb debugger and have tried every combination of usb storage on/off and every usb port on my computer to make sure, all to no avail. I went looking for the LGE Virtual Modem drivers but couldn't find anything, I don't have a ports or modem category on my device manager even after showing all hidden.

Can anyone help? I've tried everything and I am completely out of ideas.

I'm using cyanogen mod 10.1 on an lg optimus one.
[Optimus One, P500, V General] ibub:
Virtual modern appear with phone connected.
[Optimus One, P500, V General] Toxic_Ninja:
I flashed CM10.0 to see if it would fix it, but when it was booting back up I noticed windows did it's "installing drivers" thing, one of the drivers was the LGE virtual modem and it failed to install, had the little red X next to it. Is this an issue? It's to be disabled anyway so not being there can't be a bad thing... right?
[Optimus One, P500, V General] ibub:
In the case of flashing baseband, I think that is a good thing. But I honestly don't know what function the driver performs. I could guess that it's for tethering. But again, I don't know.
[Optimus One, P500, V General] Toxic_Ninja:
Thanks for the help anyway.

I figured out the problem, I had to be in recovery mode... nowhere in the instructions did it tell me that. But whatever I'm good now.
[Optimus One, P500, V General] ToolPunk:
Awesome.. followed everything and it kept giving me NV2 fail. tried it from emergency mode and now the phone is stuck in emergency mode and when I plug it into the computer it doesn't even detect it... just dandy. Cant boot into recovery, it only boots into emergency mode.

---------- Post added at 02:18 AM ---------- Previous post was at 01:28 AM ----------

FIXED... If this happens to you.. and this happened because I tried to perform this in Emergency Mode and this app got stuck on AWS Burning so I disconnected the phone. All you need to do is remove the battery, wait a few and connect your phone with the battery removed and perform the same steps.

Now this ended with download complete but I do not know if it actually gave me my v10 baseband because I have Miks and I have the CM7 slew of numbers where my baseband version should be. Good thing is I can at least boot the phone again.

I tried doing it from the Recovery and this app first couldn't find my model then it just kept timing out and different points.

[Optimus One, P500, V General] moiwillys:
Hello there I have to be in what mode to start the operation of the flash? Should I leave my phone off and plug the usb cable? Should I turn on normally and plug my cable or I have to put in emergency mode and connect the cable? I tried the first two options but lgmdp does not recognize my phone. So I go into emergency mode and the software can clearly see the COM port and I started the flash. It makes the download until the end. I have not see Nv2 backup step. Now my phone reboots but the pc(Desktop windows 7 x64) crash simultaneously. I restarted the operation and the pc crash again for restarting the phone. I told myself that pc that has a problem and I changed machine. Always the same, the new pc (laptop toshiba windows 8)also crash when the phone restarts. Oddly the phone is not bricked. Base band version is no longer unknown and now it recognizes the sim card. Calls work without problem but I think there is a problem because the operation did not complete successfully. What should I do? Please help me and thank you in advance.
[Optimus One, P500, V General] ibub:
The NV2 is backed up at the beginning of the process, before actual flash. To be sure, look into the folder where LGMDP resides. You will see a subfolder named after your IMEI, and a folder inside that named _ COM_x. This will hold NV2 files(179kb) from each attempted flash. You can use these to restore, by copying one into the folder containing LGMDP, and then running program using restore option. Although it sounds to me like you now have a healthy V20 baseband, so you should not need to restore. If you choose to restore, then you will have V10 baseband again. You should also see your IMEI in About Phone. [emoji4]
[Optimus One, P500, V General] sintoo:
Hi everyone,

My IMEI (inside home/settings) says unknown after I did the procedures outlined in the thread.

(before this, IMEI is okay, but Network is Unknown).

The problem during this procedure was that there was no .nv2 file but only a LGE_myIMEI_date.XML file but inside, there is only some header, no IMEI inside this XML file.

Since I recorded my IMEI number and IMEI SV number, is there a way I can inject it some how back ?

:( Please help. Thank you everyone.

Before today:

I was on the new baseband because I updated (via LG official update windows program) to latest 2.3.3 for Koodo (V20a , P500h). Then I upgraded to 4.4.4 OS2SD no problem. Android runs fine. IMEI is there in settings. But Network says: unknown.

UPDATES:

- I reflash stock firmware (123MB) V20A_00.kdz (koodo.dz) and got back IMEI. YAY .... YAHOO... YIPPEE ....

- Stock didn't make the phone exactly 100% like originally when it was stock (because the Network is still unknown and No Call/No message can be made.

- So now I'm back to the initial problem yesterday: Android working, phone number/IMEI are shown, but No Network.
[Optimus One, P500, V General] ibub:
Go to settings, and under "Wireless and Networks" select "More", then "Mobile Networks", and "Access Point Names". Look to see if your APN is listed and selected. If not, then you will have to add a new one. If you don't know the correct settings then you should be able to get them from your provider. The reason you didn't have data while using CM-11 may be because your APN was not included in APNs.config of the ROM (would need to add it after flash also) .

LOL I ruined this phone!!

I had this phone stored as a backup for a couple of years and since someone stole my Moto Razr, I figured I'd use my old Optimus One.

It had a Froyo ROM so I installed CM11 via Clockwork and got no cell signal. After some reading I figured it was on the old baseband so I installed the drivers which were pretty flaky on Windows 10.

LGMDP wouldn't recognize the phone and "Modem" wouldn't show up on Device Manager so I put it in emergency mode and voila LGMDP recognized it (emergency mode), after that I followed the instructions it all seemed well until the phone rebooted, I guess the drivers crashed and they crashed Windows 10 (BSOD) and then after I restarted my computer went to the folder where LGMDP was and there was nothing on the NvBackup subfolder, just some XML files next to the LGMDP .exe

So now I don't have IMEI or baseband or anything :(

Because you don't have installed the thing... not having it, is the same as disabling it.

because of a weird reason, the second time I did this tutorial, the modem thing appeared, so everytime you are going to do this, make sure you dont have it the thing installed, and if it's installed, disable it, or in the middle of the process it will fail.

everything was going fine, and as it was restoring the NV, there was a powercut.

the rom boots up, works, but i cant install any app (it gets stuck at the progressbar). also when the root patch is applied via CWM, rooted apps dont detect su access, although i can see the su app in the menu.

so i flashed again, and this time, at completion, it fired loads of nv restore faliure messages. and still my prev problems persist.

totally irrelevant for the users here

switch between ROMs

.

Uh... Way to confuse people here. Again:

v20? baseband(where ? stands for ANY and ALL letters) is ONLY for the ROMs explicitely specified in the first post and other ROMs based on v20? LG ROMs. There is no other ROM at the moment which would

not

be based on LG v20 and would work with the v20 baseband. When such ROM comes out, the developer will mention that for sure in his howto.

v10? baseband (where ? stands for ANY and ALL letters) is for all other ROMs.

This was posted by another user:

don't worry , stay calm i brick'ed my phone like 50 times, i brick'ed so bad it diden't want to start, power button was usless.

TRY this:

- remove battery , while holding the UP volume key and back button connect it to PC via USB Emergency mode should apear , then open KDZ and install via 3GQCT and EMERGENCY an original/stock firmware ( Froyo 2.2.2 v10E.kdz http://www.4shared.com/file/O3Nw1b4s/V10E_00.html )

- after KDZ finishes an animation will apear , then you must put back the battery.

- things that you may encounter , errors in KDZ , phone fails to start after KDZ resets it , KDZ successfully installs rom and powers off phone when you power on phone it stopps at Android logo, sometimes the android logo animation work's and lags for 2 3 seconds (do a battery pull, put it back then power on the phone if it lags then you must reflash) , you must do a battery pull, connect usb without battery and chose DIAG in KDZ, reflash.

​

- as i was saying i killed my phone alot of times, KDZ always helped me bring it back to life , be patient.. and if you get alot of errors and flash meny times the phone gets hot , leave it to cool for a while and then try again.

you can install Froyo 2.2.2 v10E.kdz
