[Q] LG P500h with recovery issues...

Okay, so I read and read, searched and searched. So far I'm pretty stuck.
I did a ton of research before taking my LG P500h, and flashing the ROM because I wasn't a fan of the Froyo android setup. Did everything properly, ran an nandroid backup, everything that I was told to do.
Rooted using Gingerbreak APK, custom backup using Amon_RA custom recovery. All done using the latest USB drivers LG updated me with.
I am currently with Koodo Mobile here in Canada. Pretty much an offspring of Telus Mobile. Currently I am running Cyanogen Mod 7 the 6.5.7 beta build, and the phone is not bricked, or giving me any errors or hassle.
The problem is that I cannot use the 3G network or use the Koodo network. It only defaults to Telus towers. No android market showing up anywhere either. From what I've found on here, there doesn't seem to be a bugfix solution to this, and no settings I've been able to change on the phone has helped my situation. Maybe I missed something.
So, I decided to take it back to where I began, back to Froyo 2.2.1 . This is where it all went wrong. Tried going through the Nandroid backup and restoring that, I was given an " Error : run 'nandroid-mobile.sh restore' via adb! " . Okay, I'm not exactly a Java programmer so I'm a little intimidated. I do however have Android SDK going on my laptop.
Some more searching revealed the KDZ_FW_UPD.exe flashing method. I got the right KDZ file for my Koodo phone, V10V_00.kdz and began the process. Everything checks out, good to go, started update. Wait, phone not found? WTF! My laptop recognizes it, says my phone is connected and working. No problems here, just can't find it? UGH.
So, I need someone to either give me info on getting it to flash the kdz, or get Cyanogen Mod 7 working properly on my device.
Please help, I'll fully admit I'm a noob to this, and not an expert programmer either. But, I know computers and I fully understand what I have done so far to my phone. Just not enough to fix it.

Okay, I have gotten some things working on my phone. I think I am settling into Cyanogen Mod nicely. I missed the Google apps flash zip so I have my market and stuff. Its a shame the data does not work though. Oh well I will keep updating as it gets developed.

GOT IT! finally...
Finally got my phone recovered to OEM specs. I had to restore my computer back to before I installed all my drivers and reinstalled all my USB drivers from there. Phone connected to USB properly, ran the KDZ updater, and it sucessfully installed the V10V kdz. All is well.

finally good luck.. enjoy androiding..

When you flashed the cyanogen mod rom what program did you use to flash the phone? And how did you make a rom backup? When you reflashed the stock rom did it still have all the original bloatware?

LG Optimus P500h TELUS became dead during Upgrading
Hi everybody!
I have LG Optimus P500h Telus. I purchased from Kijiji. I don't have any papers or documents for that so i cannot claim its warranty.
I was trying to upgrade its version during upgrading my device was stuck so I disconnected and plugged out its battery and inserted again. When i tried to turn it on. It never turned on again. It never ever appeared emergency mode again. I tried for several times by pushing home, power, and volume up and down buttons, and escape buttons. Now its just like dead. It never showed any sign of life. If anybody have any idea what happened with it and how I can recover or where I should take this one for repairs. I am in toronto, canada.
Your help and suggestions will be appreciated.

HELP!

Cant reflash Baseband since Phone is back from Service

Hello,
i gave my phone to service 3 weeks ago because my Power Button doesnt worked anymore. Yesterday i got my Phone back and they said they changed Mainboard and i have a new IMEI. So since ive got it back i cant reflash ginger baseband which i had already on the Phone before i gave to service. Progress ends at 0% with EBL error.
Can anybody help me??

You could flash V21a (can be rooted) or V21b. They are both gingerbread ROMS:
http://forum.xda-developers.com/showthread.php?t=1287236
It will probably invalidate your warranty though if your phone isn't a European open model.

Hmmm the same thing happened to me with the power button before christmas and they replaced the mainboard. I seem to remember also have the same problem flashing the baseband but i got it to work eventually. I cant remember exactly what i did but i think it had something to do with the drivers on my computer and that i had to start from scratch. It worked eventually so dont give up. Try reinstalling all the computer software and then try reflash.

Help with Bricked Phone

Alright so I have a LG Optimus P925 that was updated to Gingerbread. I rooted my phone with megatron and installed the Cyanogen Mod. However, there was a slight problem with it. It would say I am not connected to a network. It was working fine before I installed Cyanogen so I decided to revert back to stock form. This is where the problem had arised. I had no idea what I was doing and bricked my phone . NOOB
Anyways, so I used the method in this link:
http://forum.xda-developers.com/showthread.php?t=1629307
and now I am back to a stock LG Optimus. But now it says the model is p920 instead of P925. Also, I am on Rogers in Canada. The Rogers logo would appear when I was booting the phone before but after I bricked it and brought it back to stock, it does not show up anymore. Furthermore, it is not detecting my sim card at all. I try to select Rogers from the mobile networks list but it says it cannot connect at the moment.
One final thing. It still says I have no mobile network.
Like I said, it went back to p920 instead of P925. Also, the android version is 2.3 and it is V21d. I dont know if this information will be of use but hopefully it will. Please help a brotha out!!!!!

Try flashing a P925 rom using the official LG flasher. I'll update the guide tomorrow with the P925 files.

Thanks for the response. Everything is sorted out now. But on to my next question. While I had the CyanogenMod installed, it would say I have no service. But before, on the stock rom, I had full bars. I couldn't make a phone call, set my APN settings, or choose my carrier from the options menu.
Does anyone know what thats about?

Not sure. Might be a corrupted baseband? Or the radio-related files screwed up somehow.

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.

[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.
