Umm I don't know but I don't think so. I can't help sorry, but I'm sure I have seen posts in this thread that tell how to recover from this situation. But it might have been another thread, I suggest you look through all the thread titles in the Q+A section and post in one that looks relevant. Make sure to quote your posts here and mention the lack of response, so that you don't get flamed for double-posting.

Good luck bro.

Best way is to properly update to the new lg gingerbread where the new baseband came from =), and then flash custom roms etc

I did the same as you and thought my phone was bricked, I tried this and it really worked, my phone is back from the dead.

Question

With so much talk going on around these forums about Baseband via LGMDP, I have to ask this: I am currently running devoid froyo final with Franco Kernel v18 with superblue theme v5 do I absolutely need this new baseband, what are the benefits of having this new baseband ? I really have liked using froyo final, it's fast and doesnt suck up to much battery but I have heard that those official roms are better in many different area's of performance, but there's nothing flashy about them atleast no in the looks department. I would like to know what is the best rom they've got available for the LG Optimus T ( I do understand that people will have different views on what's better). Before I get to off subject, which I seem to have already done, back to my original topic ? Do I need this baseband for devoid froyo final ?
[Optimus One, P500, V General] lekhwani:
No. You don't need new baseband for devoid froyo final or cm. New baseband is required only for newly released official gb. New gb doesn't bring much improvement from froyo roms. Major pluses are the audio effects and selective copy and paste features only. Rest is better in froyo 2.2.

But CM 7 has much improvement. It has the maximum speed in UI, 2D and 3D. It has audio effects, native theme Chooser, rom manager, awesome cm settings etc.

Hi, I have Megatron ROM android 2.2 and I want to flash to GingerLOL 1.5. So I wanted to flash the baseband P500-v20G-baseband.7z.

Now I have no GSM. Will that change after flashing to GingerLOL?

When I was flashing the baseband or when I try NV restore, I got this error:

1 NV_ITEM NV_FAIL_S until number 157

EDIT: ok I flashed baseband P500-v10E-baseband.7z and everything is allright. I guess I have to first do KDZ to 2.3.3 ROM and then go for the new baseband and GingerLOL
[Optimus One, P500, V General] lekhwani:
Your first step was alright. After flashing v20g baseband, you just needed to go to recovery and wipe everything and flash gingerlol.

Lost IMEI

Guys, I hope someone can help me troubleshoot. Here is everything I did, from the beginning.

New P500 on Movilnet Network (Venezuela).

-I flashed CWM through rom manager.

-I did nandroid backup.

-I updated to BB v20 with the LGMDP tool. Update went well, everything was as described in the instructions.

-I flashed nightlyFourE v4.6 Rom

Everything was working perfectly. So far so good.

Now I need to move to another operator, so I need to sim-unlock the phone. I go to the IMEI unlocking pages, they tell me to use code 2945#*500# to access the menu where I can enter the unlock code. As a precaution, I don't buy the unlock code just yet, seeing if I can get into that menu first. I can't. It doesn't even recognize the code, just ignores it as a number. I figure it must be the ROM, so I boot into CWM and restore my nandroid backup of the stock ROM. Restore works fine, the ROM comes up, of course, no signal 'cause I have v20 BB and stock came with v10.

I use the code, and this time it recognizes it but it instead of the unlocking menu, I get a "your phone is not personalized" error. I research a little bit and decide to look up my IMEI, and that's when I realize that my IMEI is gone. not coming up through *#06# nor in about phone.

I'm pretty sure it was ok when I had the nightlyFourE ROM, otherwise it wouldn't have been working well as it was.

I have the original .nv2 backup file from the time I updated to v20 BB. How should I proceed? should I try to downgrade to v10 again? else, how can I restore the .nv2 file? should I reinstall the fourE rom? There are too many combinations of things that I could try right now and in very different order, and I don't want to mess things up worse than they are right now, so I don't want to try things at random.

I'm not an ID-10-t, and I can follow instructions, if someone can help point me in the right direction. What should I try first?

Thank you very much

EDIT: In case someone finds themselves in a similar problem as mine:

Found and downloaded an official v20g ROM (it happened to be romanian, I think)

Flashed it via LGDMP, only changed language.

The 2945#*500# code now worked and the IMEI was there. Bought the NCK code, entered it, presto, O1 sim unlocked.

Re-flashed my choice of ROM.

Screwed Up Process

Howdy,

I ran this process using an XP virtual machine. things got a bit screwed up, this is what I did to make it work:

1) set virtual machine to always control the phone

2) disable LGE virt modem

3) once phone reboots, reboot into recovery

4) flash rom again (I had previously flashed oldbbfix.zip)

5) profit!

V20H

Can this method be used to flash V20H baseband? Does anyone have the required files...
[Optimus One, P500, V General] sweetnsour:
You can grab the required files from the V20h kdz:

1. Download V20h kdz

2. Use "LG-Utils-0.4.2" (available on xda or you can google for it) to extract cab file from kdz.

3. Extract dz from cab file (I used WinRAR to extract the dz).

4. Use DZDecrypt to extract files from the dz.

5. In the first post of this thread, the files for the V20g are provided. Replace these files with the files that you extracted from the dz in Step 4 (amss.mbn, amsshd.mbn, partition.mbn). Use the new files in LGMDP.
[Optimus One, P500, V General] melando:
Thanks, attached are the V20 files listed above (from I think a Romanian ROM) in case anyone wants to try

Try Oldbasebandfix

Meanwhile, use the oldbasebandfix. Applied by pushing three files to /system/lib/. I keep them handy on my sdcard, ready the copy when I flash a new ROM. Once copied, no need to reboot, will simply work after a few seconds.

If the baseband is till unknown, try restoring some com.lg files from the Froyo backup (you do have one?). I looked for anything with a suggestive name. I believe that com.lg.providers did it but I copied several. (There are no com.lg services shown running on the handset.) Recopied the oldbasebandfix files and voile.

in A tight situation- no data,network

hello xda

i screwed my phone's something very badly.

after flashing aokp build 40 consecutively two times. my network's gone haywire.

first, i have to turn airplane mode on and off several times just to get a 2g network.

and then when i enable data, it takes more than 1 minute to just come up with the 'e' sign over the network bar which is fluctuating by the way, like a sine wave or something.

and then, i try to load a simple web page like mobile.verge.com in opera mini and it takes more than two minutes to show up. its like my connection is giving me 2 or 3 bytes per second download rate.

will flashing the new baseband will somehow refresh the network settings and make it usable once again?

please do help, as i am struck in this thing for three days and the cell sim is basically unusable since.:silly:
[Optimus One, P500, V General] Sau123:
Hey bro u wil have to update the baseband to V20..!! your cell is not searching the network. This is because you have flashed The CM9 without baseband update..!! Update The baseband. The BEST WAY to Update baseband which has 1% of chances or less than that of bricking is to connect the phone to pc suite and click on phone software update. It will update it !! NOTE : YOU MUST HAVE USB DRIVERS INSTALLED!! I didnt tried this process nor the KDZ updater I tried this process which is basically official..!! JUST DNT UNPLUG THE CELL WHEN THE SOFTWARE IS BEING UPDATED :D
[Optimus One, P500, V General] creagrox:
Thanks for the reply once again sau .

Now, I have been using cm9 since December (and cm7 in March ). So, i have the new baseband already. And i used the dreaded kdz method when I first changed from froyo to gb2.3.3. But whats unusual is the fact that it works flawlessly when I change it to 3g sometimes. So i am having a big confusing turmoil here.

But i will try your method after updating pc suite and let fellow xda users know how it went.
[Optimus One, P500, V General] Sau123:
you are welcome mate my method is best and safe..!! and if something goes wrong then you can claim at LG care center that i was updating throuugh pc suite only (if somthing went wrong). They will charge you less as the chances of bricking here is 1% that also if you disconnect your cable :D
