hi everyone, just one question: What have i to do? I flashed the cm9 beta4 on my p500 there wasn't baseband, it said unknown baseband. So i went to the thread to read about baseband, and in the first post it said:"rom will be only new baseband 'cause cyanogenmod support it natively!" i downloaded the v20g baseband and put the baseband on the phone following step by step your instructions (i did this process few days ago with cm7 and all went good), and now i'm stuck in emergency mode and lgmdp in timeout after 20 min of amsss burnig. I didn't touch anything as you said..

What i have to do now? Unplug the usb and reboot?

Edit: I unplugged the phone and kdz doesn't work.. The phone is bricked

i had already read it somewhere in cm9 thread....
Do not flash baseband while on cm9 as while phone gets restarted, it isn't recognised in cm9

Dok should put in first post "not to update BB while on CM9".

I flashed new baseband while i was in Perfect peso2.2 and it got a bunch off errors, but after clicking ok it said download successful, but the phone stayed shut down so i needed to unplug it and turn it on. On first boot it bas black screen with bunch of white letters saying some kind of error and phone restarted and after that it booted normaly, and everything worked well, exept that in baseband there were just a few strange symbols and not baseband version! :confused:

Anyhow, then i flashed ICS beta 4 and in baseband version it says: V07u-000-000-MAR-23-2009? Is it right??? I thought it should be v20g, but gsm works regardless...o_O So i tried updating my BB once more and everything went ok without errors this time, exept when it finished, phone was again off so i needed to unplug it and turn it on, but it still says baseband v07u???:confused:
It all works well but is this a problem?:confused:

It's now moved to 'Download end' with 'Error! AMSS' written at the bottom.

Phone is still in Emergency Mode.

What next?

Can I assume that due to the lack of response that I am now the proud owner of a plastic frisby?

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.

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.

Beware, it may not work first time, it certainly didn't for me but keep trying and it will eventually.

I tried..but it showed Error Erase after NV Backup...!!
I dont kno about it.
I would try once again but it wont brick my phone ??

well for me, upgrading to new baseband with this method was really a piece of cake...:Dit was the most safest way either, so I was pretty confident that I won't end up with a brick...did u read all the FAQs?? like disabling LG virtual modem and all???
or try upgrading to official GB...u will automatically get the new baseband with that...

    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!

    Reviving a dead P500!

    Hi,
    I'd like to share my experience for those having problems with nv2.
    3 days ago, my Optimus One couldn't boot at all. The only working part was the Emergency Mode. KDZ couldn't fix this as it didn't recognize the chipset.
    I used LGDMP and upgraded to V20 Romania, but there was no signal. I figured out that the NV2 was gone! But the good point was that luckily I had backed up my NV2 a few months ago. But I couldn't restore it at all. LGDMP said: "NV2 file doesn't exist". Actually this file should be in a folder named as "_COM_6_". Notice that 6 is the COM port I used in my own PC. Yours might be different. Then create another folder having the same name as your IMEI and put _COM_6_ in it. For example: LGDMP/3540430**********/_COM_20_/NV_P500_20110808-212402.nv2
    But the point is that the NV2 can't be restored while the phone is connected to your PC in Emergency Mode. So all you have to do is to install a ROM, whatever it is (I used CM7), and enable USB Debugging, and then connect it to your PC. Now Open LGDMP and Select Port, and finally NV2 Restore.

    I was happy I could bring my dead mobile phone back to life.

    I hope this can help you.

    Which file should i flash if i want to switch to cm7? If i have to flash p500 v20g baseband to get back to cm7, the name seems to be a misnomer.
