So yes...
There's very instructions of how to flash the new baseband to the phone... but here is also the v10 baseband,.. and is not clear if you can flash the old baseband FROM the new baseband, with the same procedure.
In fact there's a Q/A which suggest it's impossible...
From the post:
Q: This appears dangerous. Is there an alternative for switching between ROMs based on LG's GB and others like CM7?
A: Life is dangerous. If you want to flash CM7-based ROM (like mik_os' CyanogenMod 7, andy572's Gingerbread ROM or Noejn's void. #forever) and have the new baseband already, there is a baseband fix by mik_os but....
I just wonder if I can flash it back so I can flash again stock Froyo 2.2 to my phone.
A little tip...
a quite few apps that worked awesomely on Froyo, now FC just before opening.
Gingerbread update sucks...
Thanks for the help.

Hi All,
I searched the forums and though this question has been asked couple of times, I failed to get a satisfying and consolidated answer, so seeking a solution here.
Scenario: X10i, 2.3.3 Stock, rooted using aZuZu. Self-customized framework-res.apk and SemcUxpRes.apk and a truckload of apps. Poor battery life, slightly laggy.
I am equally drawn towards CM7 as well as Wolfbreak 4. I know that both are completely different flavours, but much as I love the Cyanogen innovations, so do i love the tweaks done in WB's ROM with minimal changes to the UI.
Questions:
When I backup my current ROM using xrecovery, what all elements get backed up? More precisely, if I make a backup of my stock ROM using xRecovery, will it backup all the installed apps, conntacts, messages and appdata?
If I restore this backup at a later date, will I be able to get back my phone in the same state as it was backed up? (e.g. I am on level 14 on angrybirds and I made a backup, wiped my phone, and then restored the backup, will I have to start Angrybirds afresh or I can continue from where I left off, as though nothing had happened?)
Is it possible to have multiboot on the X10? So that Everytime I boot up, I can choose whether I want to load the CM7 ROM or the WB4 ROM?
Thanks in advance.
1 yes, the things you mentioned will be backed up (but not the baseband & the kernel)
2 yes, you can play angry birds from where you left off (but as I said you can't backup/restore baseband & kernel)
3 no, not yet. Before official gb there was a solution for dual booting a 2.1 rom with a 2.2/2.3 rom, but I believe dual booting two 2.3 roms is not possible for now

Thanks for that! Just a couple of doubts here:
As you mentioned, the BB and kernel wont be backed up. How exactly will that affect my device? Will it lead to any compatibility issues if I restore to a backed up ROM?
Do I need to keep a note of the Baseband and Kernel versions of all the ROMS which I intend to flash, and flash the corresponding bb & kernel versions prior to recovering a backed-up ROM? To be more clear, supposing I am on bb .71 and kernel 2.6.29, and I flash a new ROM with a different kernel. If I wish to go back to stock by recovering my backup, will I have to flash the bb .71 and 2.6.29 kernel again?
I noticed Woflbreak's ROM uses kernel version 2.3, but I am on a different kernel version (2.6.29). Do I need to downgrade to 2.3 kernel before using the WB ROM? Won't an older version of the kernel cause a drop in performance?
well to sum it up yes you need to keep a note of kernel & baseband for avoiding any compability issue, the kernel part is pretty easy, 2.1 roms all use the same kernel & 2.3 roms another kernel, If you want to go from a 2.1 rom to a 2.3 rom you need to flash the appropriate kernel (& the baseband) with flashtools, but switching from a 2.1 rom to another 2.1 rom or from a 2.3 rom to a 2.3 rom shouldn't be a problem kernel-wise, you just need to pay attention to the required baseband & flash the right one if necessary
what rom are you on?
& by the way 2.3 on Wolfbreak is not the kernel, it's the android version
the bb and kernel are in a 7zip archive linked on the page for wolfs 4.0 along with the newest patch. it explains how to do it all on the page. You must take into consideration when trying a new rom the basebands that it is made for.
Basebands can be found here.
Most newer roms will tell you in the post which baseband you need.
Also see if users post other working baseband versions along with kernel versions. how to use a custom kernel with it and a post explaining custom kernels is here.
I flashed my phone with cyanogen 7.2 yesterday(it was running stock gingerbread 2.3.3) and lost network access. Everything else works fine ony there is no network reception. I have tried resetting the phone, flashed another rom (icslunar) but still no luck.Pls Help
Okey man, i will play Sherlock Holmes. So:
I wondering that you didn't read FAQ, Guides etc.... like me ;p
But also i think that you are NOT as tricky as me so,
if cyanogem 7.2 is a next version of 7.1 (which has OLD BASEBAND) it seems like 7.2 is for OLD BASEBAND TOO.
What is more you have some ways to fix it:
1. Install patch from mik_os from his 7.1 CM thread.
2. Flash old baseband because stock GB in LG i equiped with new one. >>CLICK<<
3. Flash rom for NEW BASEBAND like Nitrgen - it has very very good performace.
You choose, I suggesting
I am in very good mood today - chrismas ;p
Press thanks if you want..
Cheers
Ok got my network back by restoring previous baseband but data still is not working!
Ok, here's your problem.
When you upgraded to 2.3.3 stock gingerbread, you eliminated the possibility of any ROM based on the old baseband for .32 and limited your options to ROMs supporting the NEW baseband, .35.
If you want to switch to the old baseband so you can use those ROMs I suggest you use this guide but be VERY CAREFUL.
As for your data problem, go to Settings--> Wireless and Networks-->Mobile Networks--> AccesPointNames and check. If it's empty, you should call your service provider and ask them for your GPRS/EDGE settings.
Hi all,
we used to be able to switch between roms with the same kernal. There are so many roms and kernals I don't know is there a kernal we can use with the latest MiniCm 2.1.7 and stock 2.1?
MiniCM7 need nAa kernel, and we know that nAa is kernel for custom GB rom
for stock 2.1, I just try ZP kernel, and I think kernel for both MiniCM7 and stock is not yet build
Thanks for the info.
Only on rare cases do I need something from the stock ROM and sometimes if things go wrong I might need to go back to that ROM for a moment, but I miss having one kernal for both...it was so easy to switch.
I can't complain though, the dev on the newer roms is just brilliant.
If you try to use ZP kernel with stock 2.1 eclair, you will not be able to use your touch screen. Modules are not same for GB and stock ROM.
Hello XDA developers.
Im a bit confused, hope you could help me..
I have an LG Optimus P500 H , and i want to install a cyanogenmod ROM with gingerbread.
Of all the information i had gathered, my phone is in the OLD baseband, with a kernel version: 2.6.32.9
I have readed that i have to install a new baseband for the cyanogenmod "P500-v10E-baseband.7z " from this thread http://forum.xda-developers.com/showthread.php?t=1149530 , is that correct?
Wich version of cyanogen do you recommend me to install? I live in argentina and i dont want to lose my 3G/HDSPA/EDGE connection.
The other thing is, that all the links are dead because of the megaupload closure. =(
Thanks.
You seem confused. New baseband is v20. As long as you are not on T-Mobile, data and 3g should work fine. If you are, you can try and if it doesn't work, revert to v10. One of the network frequencies doesn't seem working with v20 (I Think its 1800hrz - correct me if I'm wrong) and as long as your network isn't dependent of that frequency, its fine.
Try out adfad666's N2 or a cyanogenmod nightly if you want. Lupohirp's ICS is almost complete and its for the new baseband, and as far as I know, the newest oxygen tom is too

Or if you don't want to flash new baseband you can try the old baseband fixes for cm7 or cm9.

Thanks-a-lot!
I think i will go for "CyanogenMod 7.2.0-RC0-OptimusOne-KANG [.32][.35][BothBasebands]" when adfad666 releases the removed link, until i feel more confident messing with the basebands and kernels, hehe..
Last year i had a HTC, wich i flashed so many times i lost count, now i see this as a whole new world!
PD: Dont like much the homescreen of "nightly" version. I miss SPB shell so much...

you need to update to stock 2.3 you can do with lg updater tool or kdz updater also if if you don't want to update then you can install mik os cm7.1 or A8 and you can install any obb(old baseband) or you can flash old baseband fix patch you can find this patch on p500 forum but make sure 1st install rom then flash patch
any links to those roms you mentioned i've used the search and can't find which to use like do i just copy and paste on sd card then load with clockwork mod manager to reflash the phone and when you say add a patch how do i do that ? sorry if this is too much of a bother for you but how else are we to learn?
i just figured it out thx for all your help
