LGMDP not recognize LG P500 after ICS update. How to flash baseband?

---

Greetings,

I am relatively new to the world of custom ROM but have tried to research as much as possible during my spare time. I am having some difficulties in flashing the new baseband to my LG P500 and I seek your help.

Long story: I have 2 LG Optimus One (P500) with stock Froyo ROM. They both has the old baseband (v10). On one of them, I managed to:

1) root it,
2) installed recovery,
3) flashed the ICS 4.0.4 (LG3 UI, here: http://forum.xda-developers.com/show....php?t=1759908).

Two mistakes I made during the process were:

a) I did not back up,
b) I did not flash the new baseband before I flashed ICS ROM.

Now I have an almost fully functional phone but without GSM access. I tried to flash the new baseband using LGMDP, but LGMDP does NOT detect the P500 with ICS, even though

- USB debugging is turned on

This is on a Windows-7 machine. The Device Manager simply DID NOT detect the LG modem. However, if I plug in the other P500 with Froyo ROM, The Device Manager will detect it and so would LGMDP.


Can anyone please shed some lights as how I should proceed at this point?

thanks in advance,

I think you flash one of the ICS version that windows dont reconze phone,but in recovery it do,Try to flash the baseband with phone in emergency mode..

If dont work flash GB based rom so pc can reconize phone.

Till the time you figure out how to flash new baseband or whether
to flash a new baseband or stick with the old one..
Use this patch.. this will help you get GSM network.
Flash it through recovery!!

Try going into recovery, ldmdp should detect it.

I managed to flash the baseband by turning the phone into emergency mode. LGMDP detected the phone this way.

Thanks very much
