So i want to try cm9 on my p509. I've tried many times to upgrade the baseband, but whenever i do i get no gsm and my imei disappears. trust me i've followed the guide EXACTLY. so i just stick with old bb. I want to flash to this cm9 http://forum.xda-developers.com/showthread.php?t=1614420. My question is if i flash this rom will it brick my phone (because i'm on old bb). if it won't then can someone post a link to a old bb fix so i can get data working on my phone when i flash it. I need this info urgently because i'm about to travel in a few hours and want to flash before i do. Thank you!
It will not brick your phone, and I haven't the FIX yet.

i've followed all the directions, and it doesn't work. i downloaded the v20 file and extracted with winzip to update to v20.
Do you've restored the NV2-file after flashing the new baseband?
Just a note, try not to mess around with nv2 it can create such a hasle in the end

Guys i'm stupid. i was trying to update the baseband while using cm 7.2 (i used an old bb-fix for data) so i flashed cm9,, and then updated the baseband and it works!!!! so now my question is, if i re-flash cm 7.2 and am still on the upgraded baseband will it work? (yes i know i can just restore a nandroid backup, but i just need to know this information)

I think, it doesn't work. The ROM boots, but you have no signal etc. Even restore a nandroidbackup doesn't downgrade the baseband.

Why would he need to downgrade
Both cm7.2 and cm9 run on new baseband,right?
Though not sure what restoring nandroid will do in this case as then it would have old-bb fix on new baseband:cyclops:
yeah i hear ya. so is it reccomended that i reflash cm 7.2 so then i coulld stay on new baseband? then it would be easier for me to flash roms for new bb right?
okay... i am gonna explain this and hope i am right..sry for big post
Our phone has many partitions like(system,data,boot,recovery,cache,etc)
The mbn files that you see in P500-v20G-baseband.7z are partition images(or pieces of it or bin file or something similar....am not sure)
Now to install a custom rom, you format system,data,cache(or boot too in some cases) and then flash the rom, which basically copies new files to these partitions.
SO,custom rom does not affect other partitions present on your phone.
However when you install stock through kdz, it basically wipes your whole phone and install each partition again(including the one containing baseband).So, after installing a kdz...you are stuck with that baseband no matter which rom you install through recovery unless you install a kdz again with diff baseband.
The lgmdp method only changes the partition containing baseband (amss.mbn). So,again custom roms have no effect on baseband.
Now, to answer your ques.

No, you dont need to reflash any other rom. You ARE on new baseband now and can flash any rom for new bb and it will work.
Note:All info above may or may not be entirely correct.Its just how i think it works.:good:

Because you need to reflash the darned ROM which you have screwed with the non-working patch. Read!
i even reflashed the ROM dude........bt same prob
plz gimme a link of ur kernel version
RoM n baseband
Well, flash a full stock ROM via KDZ and move on. When you have done some reading (which clearly hurts your brain), come back with some non-PEBKAC issues. While you have mismatch between your baseband and ROM, you have no GSM and data. It is written in the howto, but then again, too long and boring to read, huh?
Bye.
Hello ppl. I have flashed to new baseband w/ Cyanogenmod 9(lurpohip) and franco's newest kernel. I can call and send text messages, but data doesn't seem to work. Would appreciate help. I've gone through both how-to's pt. baseband LGMDP.exe. Also did a full data wipe before installing the rom.
I noticed some NVRESTORE NV_FAIL_S errors when I changed to new baseband in LGMDP.exe though.. Any ideas? Tried to change 3 times, same errors occur.
Thanks in advance. Sorry for being a noob, but I have been searching for 2 days.
Unfortunately, CM team has removed some frequency from sources and now, with some carrier (eg. Vodafone or 3 IT), data connection doesn't work. I have the same problem. The solutions are:
1. Not use a CM rom
2. Use old baseband with patch for CM.
3. Wait for a fix

I was on stock GB 2.3.3. then i rooted my phone for the first time today. i was planning to install custom ROM 2.3.4 Phoenix. then i read somewhere that i need to be on the old baseband. and i saw a guide to do that. i did the same.
I purchased ROM Manager. i tried to download ROM. it asked to do a backup, and i did that - within ROM Manager. then it showed me few available ROM's. and i clicked the Mik's CM 7.1 and installed it. but there was no network. Wifi was working.
So, I tried to do a restore. but it said i can't do that because Clkwrkmod Restore is not installed. I installed it using WiFi, but it didn't work saying there was some files missing. then I thought of downloading 2.3.4 Phoenix to overcome this situation, hoping that network will comeback. i downloaded and installed it. but still no network as well as no WiFi.
What should i do now? is baseband an issue here? Pls pls.. anyone help. I know i did some big mistakes..
i will be more than happy to go back to even Froyo 2.2, my original stock ROM. i need to get network working.

Baseband question: i'm on the new baseband (was on stock 2.3, then flashed to openoptimus). I really like the look of some of these .32 kernels and roms but everything says its for old baseband.
Can i go back to the old baseband? Is there a thread somewhere? Is it safe? From my own investigation, it looks to me like I don't go back to the old baseband, but rather flash some patch to make the roms work anyway. Sound right?

It won't be OK. If your phone uses the "new" baseband, ROMs made for the "old" baseband will work on your phone (as in flashing will be successful, the phone boots etc.) and everything works except for the most important thing in a phone: the GSM/UMTS module. Which means you won't be able to connect to your mobile network and won't be able to make and receive calls. Bummer. Now, there's a patch that solves this BUT something will still be missing: mobile data. You will be able to make and receive phone calls, but you won't be able to connect to the internet using the mobile data connection (only WiFi).
So, if you want to use a ROM that clearly states it's made for the old baseband, old baseband is what you must have on your phone in order for both calls and internet to work. How to tell which baseband do you have right now it's a different discussion and we'll get there if necessary. I just detailed vlt86's answer for you to understand.
EDIT: I see you already know what baseband you have - the new one. Follow voyager20021's link in order to find out how to return to the old one.

Hey guys i have been having some signal problems with my ace, but I only have them when inside my house. This started happening when I flashed gingerbread 2.3.5 to get a custom rom for my Ace (which is awesome btw!) the rom I am currently using is WP7 Rom by Jinavs. I have googled & searched a lot and all I found was a code to change the GSM too 900/1800 but I tried the code and it said that it was invalid, the code is *#2263#. Then I read something about changing the phone's modem is this possible on custom firmware? I never had any problems when I was on Stock Froyo 2.2.1. Any help guys?
Also master reset or factory reset does not work :/
what I do sometimes is airplane mode or turn off the phone and it sometimes works
and it only happens inside my house it works fine in any other place.
Any help will be appreciated

create a cwm backup then. the point of reflashing stock rom is to get correct modem for your region. after that u can just restore the cwm backup, it wont overwrite the modem.

As we know there are two types of baseband's available for our device, old baseband which is used by froyo and some gingerbread rom's and new baseband that is used by gingerbread onwards.
To switch baseband you either need to flash baseband through lgmdp or flash firmware using kdz and both involves a substantial degree of risk of bricking your device.
What I will be telling will not actually change your baseband but will make the ROM compatible with the baseband you are using. So here it is how it goes.
-> If you are having old baseband and want to use new baseband ROM, flash this after flashing ROM

i dont have this problem when i was using roms based on the old baseband. so i am wondering what would the patch do to the system.
