CM9 with Old Baseband and maybe other stuff - Optimus One, P500, V General

Hi all,
So this is just to help noobs and similar with what I tried so that I got the CM9 port by lupohirp to work. As you know the CM9 thread is devs/geeks only and not quite intended for feedback and discussion. The same applies to the new KANG thread
P.S. Lupohirp, this is just to help you and not to take away any of your credit!!
A brief background so that those with similar situations can relate and not ask too many questions. I asked all that I needed so I don't think you should have more. And if you do, I am unable to answer most of those.
So here goes:
- I first had stock Froyo
- Then Rooted with z4root and got ClockworkMod and so on
- then put on CM7 by mik_os which works with old baseband only.
(baseband is the bit that allows your phone to talk to a cellular network)
So the baseband story once again after the hundreds of posts on it. Froyo (2.2.x) from LG has the old baseband. Those LG phones that got upgraded to factory gingerbread (2.3.x) were also upgraded to the new baseband. However coming to custom ROMs the story is different. Some work with the old e.g. mik_os CM7 and some work with new e.g. official CM7 by adfad666 and unofficial CM9 by lupohirp.
That means, since I had Froyo and then moved to mik_os CM7, I still have old baseband.
- moving to today, I wanted a new ROM and got excited by the CM7 and CM9 ports. Both said they want new baseband.
Two ways of going about this:
1. Upgrade to new baseband via the various ways (KDZ, etc) which seems to be a bit scary from the instructions though it might not be!
2. Get old baseband to work with the new ROMs. This is possible based on what I read here. The file is available here under the Old Baseband paragraph.
So I decided to go with Option 2 since, baseband can be upgraded/downgraded irrespective of the ROM. The difference will always be that only one will work by default and the other one is a patch away.
So now,
- I got the zip file for the cm9 beta from that thread
- I got appropriate gapps (ics version not gb) - http://goo-inside.me/gapps
- I got the old baseband fix from the baseband link in Option 2 above.
- I put the gapps and the cm9 zip in the root of the sdcard for ease of access
Now using ClockworkMod 5.0.2.0 (remember 5.0.2.0 is for old (and probably new) baseband and 5.0.2.7 is for new)
- wiped /cache, /data, /system, /sd-ext
- left /boot as is. This is of utmost importance. You wipe this, you're on your own (ok not so bad but if you do, do not RESET your phone, learn how to get it back and then fix it)
- and /sdcard contains the new files so do not wipe it
So then the usual route, flash the zip after selecting it. obviously CM9 first. Then the gapps file. You can do the gapps file after a restart as well.
Now everything should be ok except your cell signal. That should be dull/inactive, etc. If you go phone status it will also not have much there.
So now get the old baseband fix files. extract to a folder of choice. adb push these three files to /system/lib/ (I just learnt that you should have 2MB free in /system AFTER the copying)
P.S. adfad666 has advised against doing this because of a risk of corruption. I don't know why, I couldn't get them in any other way so I took the risk since the fix is just a recovery away, so if you do this its your own risk
I then rebooted the phone and all was well.
Tested 2G and 3G and data as well. I didn't see whether it did HSDPA or not. The SIM also had all the APNs etc ready. SMS is good too!

Thread Summary
So this here is a companion thread (hopefully) to the main dev thread. Its for people not reporting bugs but closer to how something is done. Those doing patches and stuff still go to the main thread.There is another companion thread here as well which I had not seen.
A brief summary of what has happened so far:
- lupohirp has compiled ICS for our beloved Optimus One P500s from CM9 source code. It comes with Apex Launcher as of the latest beta.
- there is active work going on and people complain about things here and there and provide great feedback.
- this thread was started for noobs trying to get old baseband to work (Many thanks to aspee's thread here for the baseband info!) with the CM9 port but I felt like helping out more so I am explaining what I know.
- some alternate kernels have been compiled whose links are further down this post.
- somewhere along the line CM team has decided that we can get official CM9 subject to some coding practices being fulfilled

Because he is awesome.

No, but you can have it.

Overclockin works, camera wont work even if u use a 3rd party app since the basic problem lies in the software(the ROM)... the system cant connect to camera...

adfad has warned against using the LGMDP/KDZ method when you are on CM9. No problems in copying a few files.

SMSing will work when you copy the file libwms.so to /system/lib as well. Get that file from the A8 rom (in /system/lib).

Will try improve this thread if time permits.
What I know does not work so far in my experience:
- WiFi status bar indicator is dull although the connection is fine
- Camera does not work with standard Camera app and Camera ZOOM FX
- Link2SD is unable to create mount scripts no matter the partition file system so its a bit of a pain now to install apps
All the above are known issues.

Thanks for that!!!
Ok so, can you get us the file so I can just edit my post and put it there. Indeed my sms doesn't work and I had not checked until now. After getting it, you or I can ask adfad666 to edit his baseband description.

Link2SD very much works with ext2 partition,using it from ALPHA3,working well with latest FRANCO_3.0 kernel too!

Has it worked with all the kernels??
EDIT: I have now added a link to sweetbinodray's thread for more support before we go nagging the devs !

Old baseband fix
The old baseband fix does not work, I copied the files from the zip folder over but my phone still has no network, can anybody help me?

---

Kernels has nothing to do with mobile data...and I'm glad someone has said something about this thread,I imagine OP faces same problem as me ? T-Mobile USA,I'd assume ? You go to flash new baseband (v20g) than flash cm9..you get working wifi and notification signal bars illuminated but no signal status icon ie...3g/hdma ? From what I know, these fixes are being worked on..

I am not sure why. I have old baseband. I flash the images as usual. And when I feel like it, I overwrite the files with the old baseband fix and everything works. Including the status indicator for 3g hspa. The wifi indicator doesn't display signal strength but everyone knows that. As far as I know some sims still have issues and that is with regards to getting apn info out of the sim.
If the normal fix doesn't work, why don't you try aspee fix?

Yes indeed kernels and mobile data files are independent from what we see here. Actually my issue was using these ROMs that needed new baseband. So a lot were asking about old baseband. So I looked around and put a thread about it. I stayed away from new baseband since its a lot more of a risky upgrade than a ROM flash!

It is risky,I had a scare recently when I had a ln AMSS error and phone was stuck on emergency mode (god I'm glad I didn't take the battery out or disconnect) I've flashed from v10e to v20g about 6 times..I stuck to v10e with using old baseband fix...I've been wanting to find a reason why tmobile usa doesn't have working 3g/hdma etc... on v20 basebands versions but I'm sure someone will have fixed soon...as far as cm9 ? I have personally not tested using old baseband fix but I've heard from more people about it not working than from people saying it works,even Arjen himself recommended me to do that,good guy...I still have yet to figure out why we can't add apn's manually

So now, for cm9, should we switch to new baseband LGMDP method or should we choose the second option on continueing with old baseband...??

I would take 2nd option
