I'm flash V20I kdz , after flash rom 4.1.1 P509 , how to fix UnKnown BB

If you flash V20I you won't be able to connect to your cell network anymore, V20I is for T-Mobile UK which uses different frequencies from T-Mobile in the US, try flashing one of the old baseband fixes.

[q] p925g rogers froyo bin ? Where ?

i have tried to search in the forums and google and could not find a original version of froyo for ROGERS P925G (VERY IMPORTANT)
why? because i have tried flashing v21e and the phone is not usable, tried ICS from xsball its reallly cool but phone or internet doesnt work... so i found a original GB 2.3.5 with v20e in it (WITH GHOST CALLS !!!)
now i want to put back the original froyo but there is nothing that i could find.
i need a bin file for use with LG FLASH TOOL , it is the only way to flash something on this stupid rogers phone!!
anyone have any clues?
YES I SEARCHED THE FORUMS BEFORE !
thx

its a kdz file from rogers, if you want to extract the bin and the fls, download this tool:

COOL!
i read alot that V21E have corrected the ghost call issue, i tried to flash it and then bricked my phone!
is there a v21e specific to rogers??? , i mean that will work for sure with a P925G rogers edition
like i said i tried flashing a V21E but bricked the phone in a bootloop, perhaps i didnt do the right thing hmmmm
and will 4G work? hmmm many questions!
I think es the 20c

V21E may not work with your country.
Use whichever baseband Lg offers to your country.

I tried every in the list without luck, some of them did allow me to use wifi until I rebooted phone, but network was unavailable for all of them
it appears I don't have IMEI after smart flash to 21e, do I need IMEI to get internet connection / network ?

No sim network

Could do with some help after doing restore via LG mobile support tool.
UK p920 that was bought second hand and unlocked to all networks I am using a T-mobile[ UK] sim card
I updated from froyo to 2.3.5 gingerbread 2 weeks ago using LG mobile support tool. The sim card was in at the time.
update successful and then rooted phone all ok. Tried doing backup of current rom with rom manager and failed. also tried orange, and rom manager,none would backup anything. tried flashing rom and bricked phone!could not even get into a boot recovery. Last resort I used LG mobile support tool to download and auto re-install 2.3.5 (without sim card in) didnt think this would affect anything. Phone booted up and all is ok, did a titanium restore of apps and settings all ok, but cannot get the phone to connect to sim network-tmobile.
Current config; model number LG-P920
android version 2.3.5
baseboard version L6260_modem_sic_01.1042.00
kernel version 2.635.7+
build number GRJ90
software version LGP920-V21e-APR 19 2012
Has the recovery loaded the correct version for my phone?
I am a noob so please reply using basic language and instructions, thanks for reading.
AW: No sim network
Have you changed baseband ? Normally it is a baseband problem.
The rom must suit with the right baseband.
And watch if you have imei.
EDIT: are you on stock 2.3.5?

Everything is stock 2.3.5 used LGmobile support tool which is a recovery tool as well. Had to use this method as rom manager decided to kill phone as described in original message.The update tool did find my imei number as it did when I upgraded using the same tool from froyo to gingerbread.

will all roms will work on this baseband
Baseband is for the radio service, that is, network...roms are built to work with the baseband. All new roms cm7 onwards are built for the new baseband. So yes, if you already are on the new baseband, on flashing these roms you get network.
If you are on old baseband you can flash the "old bb fix" (my post above) after flashing these new roms & you've got your network back.
Hope this helps...
