[Q] Sim-card NOT working, LOST IMEI after Flashing CM 7.2.0 - Optimus One, P500, V Q&A, Help & Troubleshooting

Hi all,
Flashed a new ROM for the very first time and I guess I've screwed up something.
I flashed the stable version of CyanogenMod 7.2. Everything seems to be running fine EXCEPT my sim-card is NOT being detected!
Cant find any network. Also the new ROM has completely wiped out my IMEI no. (That could be the source of the problem, dont know.)
Also, I really dont know my current or previous baseband,, err newbie!( maybe thats the cause of problem)...
Pls somebody HELP!
PS. my phone aint carrier specific and was earlier running on 2.2.1(if it helps )

Baseband problem, you was on a Froyo (10b-e) baseband, CM7 requires the 20G baseband, restoring a Nandroid should work. If you haven't got one. Then you will be using the LG flasher, good luck!

There's a baseband fix script lying around the forums somewhere that should allow new baseband ROMs to work for you. Search for something called "bbfix", or something like that.

[Q] Lost and need help please

I recently rooted and started applying roms to my nexus s. Everything was going fine until my network data stopped working.
Have tried to unroot and return to stock but cant seem to get it right. whenever I try to use clockwork recovery any update zip i apply fails. Im currently on:
version - 2.3.1
baseband - 19020AUCKF1
kernal - 2.6.35.7-g7f1638a [email protected](hash sybol that isent on my mac keyboard)1
build - GRH7
I am based in the UK and think nthat my radio could be wrong?
When I factory reset in 2.3.1 i get the official update to 4.4 which dowloads, verifies then on installation stops and wont complete.
I am confussed with all the terminoligy and find the info on here overwelming to follow correctly.
on another forum i got the response that if i dont understand the process then I shouldent be doing this. Fact is I thought I did know what I was doing until it went wrong.
Could somebody be good enough to help me through this so I can restore my nexus s to working order please?
Read this thread: http://forum.xda-developers.com/showthread.php?t=1116884
Check your phone model, behind the battery. You probably have a gt-i9020 since you are in the UK.
Probably you need to flash the correct radio. What's a good choice? If you do have 9020, anything in the list with kb3 in it.
Kb3 has no limit to how fast it can upload data, which can be a benefit depending on how you use your phone. Most people would choose kl1 which is the most recent.
Download and flash in cwm recovery. Reboot.
Let me know if that works for you.

can you make calls? if you can, check your apn settings, settings>Data and networks>More>APN and delete everything, and retype the correct values for your carrier. if calls doesn't work, follow the post above. ^

Problem when flashing CM ROM

I'm not sure if this has been covered in another thread, but I was looking around a bit and found nothing and sorry if this isn't the correct place. I wasn't sure.
I have an LG P509(TmoUSA). Yesterday I rooted it for the first time and installed CM10 on it via ROM manager. After it successfully installed, I noticed I didn't have any signal and that my imei was missing. It said "Unknown" . On my dialer I pressed *#06# and a little box popped up with nothing in it. I switched back to stock rom using LG tools and both my imei and signal had been restored. I attempted it again but this time, I tried installed CM 7 via the ROM manager along with Google apps. The same happened. I again, restored back to stock. I attempted it a THIRD time, but, this time I did it via clockwork. I cleared cache and data and installed from zip. I installed CM 7 and CM 10 though this method. Both times my imei was gone and my signal was as well. Right now I'm sitting with stock rom and rooted.
Does anyone know what's going on? Can I not install custom roms with my phone without loosing my imei?
I think you did not upgrade your baseband, thats the only reason you are not getting signal. I cant tell about p509 but i had the same problem, but my phone is p500. You have to flash v20 baseband for new roms i.e higher then gingerbread search the forum i have a link but its for p500. Not sure if both p500 and p509 baseband are same anyway here is link for p500 baseband, just ask if both p500 and p509 baeseband are same if they are same you are good to go.

I had the same issue but with cm 9 and upgrading to the new baseband fixxed it for me
Thanks for the replies guys. I was in the process of upgrading the baseband, but I fell asleeping during the back up. I'm doing it now as we speak though. :good: I will post results.
It did work! Upgrading the baseband worked! Thanks for helping me out My IMEI and service as came back.
..and by the way, I think P500 and P509 are the same.

No netwrok or IMEI number on installing CM7

Ok, I know there are a lot of threads on these topic and believe me i have spent a lot of time reading multiple threads and the end result is i am not sure how to proceed , for my particular froyo version so I am posting it here hoping some Kind soul will help/suggest me on installing Cyanogen mod 7.
So here I go.
I have an LG P500 model phone with Anroid Froyo 2.2.1 (Software version V10c-DEC-08-2012, Build number FRG-83, KErnel 2.6.32.9 ). After trying several ways finally I have rooted my phone successfully. after making a clockwork recovery of my custom ROM, I proceeded to install CM7 Stable (for P500) using my 2GB memory card with 200 MB free space, it did not succeed and got stuck with the CM7 android logo.
I cleared up my memory upto 450MB and proceeded again by deleting cache/data and installing CM7 stable. This time it did install but i lost the IMEI number and the phone could not detect any network. I got the same result when i tried CM7 RC-3 . being unable to get a working phone I have reverted back to my custom rom using recovery.
After reading so many threads about these issues, i feel that this is some kind of basband problem as mine version is V10C, Can someone please help me how to install CM7 without loosing my IMEI and netwroks. (a step by step approach would me most appreciated). Thanks in advance.
Yes you need to upgrade your baseband to V20, there are several tutorials (step by step) on how to upgrade baseband on this forum.
Sent from my LG-P500
Thanks for the reply, but do i need to install the new baseband after flashing with CM7 or prior to installingCM7, Please clarify this. as I dont want to get stuck again.
cm7 roms are new bb. u need to upgrade to v20 b4 flashng cm7. u can do it using lg pc suite or kdz updater.
Solved
I followed
tried to install V20 using this http://forum.xda-developers.com/showthread.php?t=1217504 which i found from here
I followed the steps in the thread but nothing noticable changed after doing it.
Thinking it had worked somehow I Flashed it now with CM7 but sadly nothing changed and my phone still did not had any network or IMEI even now.
I followed this http://forum.cyanogenmod.com/topic/44849-My-experience-rooting-and-ROMing-the-p500-on-Android-2.2.2..... and flashed using oldBBfix_signed.zip and whoa I got my network working again in no time.
Thank you guys for your reply and special Thanks to the people who made the threads that i have added above. :good::laugh:

[Q] No service, tried everything

I got a p500h from my friend since my razr droid died and I needed something to hold me over until I can save up for the note3. It had 2.2 on it so I flashed CM 10.1 for 4.2.2. When I put my sim card in I had no service.
I checked the baseband and it was unknown so I flashed it for v.20 and it appeared but I still get no service.
I don't have gapps installed because I don't really need it.
And that's pretty much it. I can't think of anything else to try, can someone help? I'm using a non-smart phone in the meantime and it is quite terrible.
Try the old Baseband fix, that did it for me some years ago, not sure if you need the v10 baseband coming from 2.2 but the fix should work. You can find it here on the Forum.
If nothing works, use kdz to flash the Stock Rom and start over.

Thanks, I wanted to try that but when I go to download the milk_os fix at the bottom of this page
http://forum.xda-developers.com/showpost.php?p=14743798&postcount=2
I get redirected to some bull****(lp.downloadsetup.net)
And I just don't trust this thing, is this really what I'm suppose to download?
Is definitely the fault of baseband. Some rom is incompatible with any type of baseband. Try to download from play store an application with baseband-ril match...

Sounds like you have an old baseband phone, but you flashed a new baseband ROM on it. In that case, simply flash the zip indicated below (I suggest you mount /system in recovery before flashing, even though the script auto-mounts /system, just to be sure). I'm attaching two zips for the sake of completeness; the one you want is the Use_New_BB_ROMS.zip.
Use_New_BB_ROMS.zip -- Flash this zip if you're trying to use a new baseband ROM on a phone that uses the old baseband. If you have no network on 2.3 and above ROMS, your phone probably uses the old baseband, so this is the zip you need.
Use_Old_BB_ROMS.zip -- Flash this zip if you're trying to use an old baseband ROM on a phone that uses the new baseband. If you have no network on 2.2 and below ROMS, your phone probably uses the new baseband, so this is the zip you need.

I tried to flash it but I get an error: can't copy META-INF/com/google/android/updated-binary
Should I be wiping cache for this? Dalvik cache?
I used LGMDP-v1.5 to get bb v.20 on my phone in the first place, I tried to do the same with v.10 after v.20 didn't work but it just went back to baseband unknown. when I tried to download the milk_os fix it just linked me to some phishing page.
What recovery are you using? I've tried with AmonRa & CWM 5.0.2.0 and both work. Other CWM versions will probably work, too. Haven't tried with TWRP.
If this flashed successfully but you still don't have service, then you might have borked something when changing baseband in KDZ. If that's the case, then hopefully others will be able to help you as I've never touched KDZ myself.

I tried it, here's what happened.
First I just flashed it, I checked the baseband, it was unknown. Previously it was v.20 so I tried flashing in v.10 since this was a fix for v.10 AFAIK
Still unknown.
Tried flashing the fix again just to overwrite whatever it needed to overwrite and still unknown.
I'm back to square 1 on this one.

[SOLVED] No network? bb is correct...

Hi everyone,
I have just started playing with ROMS etc. and its turned my sluggish old-looking p500 into something beautiful,
The only issue is I just can't seem to get the network to work. Wifi is fine, but no service with the SIM card I put in there. I don't even get asked to put a SIM code or anything.
I have spent the last few hours desperately trying to get baseband v20 on my phone since LGMDP was not recognizing my phone, and I finally got it to work, expecting miraculous results, but alas! nothing! Anyone have any idea what I can do?
Specifically I have installed this rom: [DEV][ROM][4.4.2][CM11] KITKAT for LG-P500 [WIP][VER-12 OTA]
but have not updated through OTA yet.
And i flashed v20g using a stock version (one which didn't come with my phone). I guess I will try flashing a stock which depends on the new bb and see if that works...
Also, I don't know if this matters, but I got the phone in canada a few years ago and am now putting a UK SIM in there.
Thank you so much for any help you can give!!!! I really want to get this to work!
-A
extra words:
Also, I deleted a bunch of stuff on my SD and know very little about how SIMs work, so if I have the "wrong kind" of SIM or if I deleted something (I have it all backed up) that I need to put back on the SD card to make this work, please let me know!
Thanks!

If baseband is correct, then check your APN ( Access Point Names ). Settings->Mobile Networks->Access Point Names.

With my old SIM, I can see the APNs from back in Canada, but when I put the new UK SIM in (which shows APNs on my wife's samsung phone) I see nothing listed for the APN.
Should I create a new APN with the same settings as from my wife's phone? Or do I have to do something else?
Does it matter wether the bb is v20c or v20g? As long as its for the optimus one I mean?
Could this have to do with my phone being locked? I'm not sure if it is locked or not... I was trying to unlock it using the code:
2945#*900#
Thanks so much for responding, I had all but given up!
but nothing happens when I put that in. Do I have to revert to stock rom for that to work?
Update:
I tried to put in the right APN info, but I couldn't save it for some reason. Doing some reasearch, I found that this might be a "Funny SIM" problem, but only see patches to fix this under CM9, and I am running CM11. Any ideas?
Cheers!

Patch may work. Old baseband patch worked thru JellyBean ( CM10 ).
What you're referring to, v20c, IS NOT baseband but software version. What version of Android was the device running when purchased? Anything under 2.3 is old baseband while 2.3 and newer is new baseband. There are two baseband patches floating around XDA. One for new and one for old. Old baseband patch can be found in my FAQ for the LG Optimus One. Post #8 I believe. FAQ

I thought I had upgraded to 2.3, but since it wasn't working I flashed the new bb using this guide :
http://forum.xda-developers.com/showthread.php?t=1149530
and made sure that it had definitely flashed. My rom says it is baseband version V20g under the about phone section. So unless this ROM is supposed to be running the old bb (which it didn't seem like that was the case) the baseband version should be correct...
Also, I had previously tried the old bb patch which you are talking about; that didn't work either. What I understood was that "Funny SIM" is a different issue, but maybe I'm just reading the threads wrong.
Thanks again for your continued help!
Solved!
Okay, so it was because my phone was unlocked. I had to:
- Flash the stock ROM
- Flash the OLD BB
Then I was able to put in the code to get to the unlock screen. Once the phone was unlocked,
-Flash new BB
-Flash new ROM
And it works! Hooray! I'm not sure how to mark the thread as solved though?
