If you didn't change the phone's baseband, you can do a restore with CWM but the restore must use a backup of your phone's original ROM and kernel (If you don't have it, ask around for it on XDA) or you can reinstall the firmware, baseband, and software with a KDZ file and the offline updater.
If you changed the phone's baseband by updating the phone yourself (not updating through LG or your service provider), you have to reinstall the original firmware, baseband, and software with a KDZ file for your phone's service provider or the generic KDZ file if your phone did not come "branded" by your service provider which you can determine by what appears when you startup your phone.
Here's where there's information about installing a KDZ file.
http://forum.xda-developers.com/showthread.php?t=1610597
Don't use the KDZ file available there because it isn't Froyo. You'll have to get the Froyo KDZ file for your phone from somewhere else.

[Q] Reversing Gingerbread Baseband Flash or Correct Baseband for my Provider

Good Morning,
After flashing the Gingerbread Baseband I no longer am able to register on the network for my provider.
The device is from Rogers but unlocked and being used on the Bell network.
After flashing I realized there may be a different baseband for me to use in Canada (just North of Toronto).
I require some help in locating a Gingerbread baseband that would work or provide me with instructions on how to return to the original baseband.
Any help is appreciated!
Thank you kindly,
- Audi2Audi
Did you set the APN manually? You have to do that.
Hello!
APN in Menu|Settings|Wireless & Networks|Mobile Networks|Access Point Names ?
I have set that to: pda.bell.ca
Is there other steps required though?
Thank you for the response!
apn settings is for internet. phone must tower of sim. may be flashing baseband again will soveit because i am tower getting for my country
If you're wanting to go back to stock froyo first you need to visit here to get your original rom... these will also flash the baseband back too
http://forum.xda-developers.com/showthread.php?t=1246678
or here http://forum.xda-developers.com/showthread.php?t=1155874
then you will need to follow this turtorial in order to flash the stock rom back on (go down to second post that one is in English )
http://forum.xda-developers.com/showthread.php?t=1244490
Although it is a possibility that the BB hasn't flashed correctly, might be worth trying it again... might also be worth trying a froyo rom to see if you get a signal then, because if you do you still have the froyo baseband on...

Thanks adixtra i always forget about the tutorial of yours
You can flash a .Bin File for Your P920 or P920H.
Ok, now this is getting bizarre hah.
I reflashed the baseband again and everything went normal as it did before.
This time I searched for networks and selected my provider. After about 5 minutes of the device trying to register on the network an error was received that said it was unable to register on this network.
However, when I got to my home screen I was registered on the network. I tested a voice call and it worked. I have tested data as well.
BUT! This is where it gets even more bizarre...The device cycles from 4 signal bars to 2 signal bars to none to 3G (from H) followed by not being registered on the network. Then a few minutes later (sometimes only after a reboot) it returns to 4 bars and begins the cycle again.
Has anyone seen anything like this before?
Thank you again for your help!

Good Evening,
Would you be able to upload the KDZ file from your update?
I am having problems with the LG Phone Recovery indicating that I have the most up to date software and halting the recovery process.
Thank you!
- Audi2Audi
Hello,
I flashed an earlier KDZ which allowed me to use the LG Update tool to restore my stock rom.
Thank you everyone for your help and advice.
- Audi2Audi.
it will tell you that but if you use recovery mode and it will download the file then you will have to unplug the phone from usb hold vol+ power then plug it back into the usb and it should download. like i said i used similiar method to flashing baseband
On my windows 7 not detect omap 4 and i can't flash baseband,what can i do?

LATAM gb update

Hi
I just checked lg mx site nd they say there's an update available and that's v21a fw
going to update and they check the baseband for those who may want it, I just need to know how to extract it so you guys can flash it.
NOTE: this baseband may be similar to the one used by rogers canada
edit: trying to recover the phone from emergency or some crap like that. will let know as soon as the results are here, also if it gives me 3g again will upload the fw (if I get to know how)
argh false positive -.- we're still on v10a it sucks, I had v21a hate mexico

[Q] Firmware issues...

Wondering where I can find and download the proper baseband to get service from my carrier...
Running custom firmware and my cell service randomly drops out. I read I may need to flash a new baseband.
If so, where would I find that, and what exactly would I need to do to install it?
Thanks

Lg G4 hard brick... need help please wiling to donate cash.

Hi everybody..
I'm in desperate need of help. After attempting to root my g4 somehow something went wrong and the phone is completely dead with no sign of life . I know there isn't a way yet to unbrick the g4 but I'm hoping somebody out there is working on it and maybe can help me out.. I'm willing to donate for the help Thank you !
What exactly are your symptoms? Does it not even turn on? Have you tried getting into download mode? How exactly did you try to root it? What were your steps and are you able to identify where you went wrong exactly?

I was trying to gain root access following this method : http://forum.xda-developers.com/g4/orig-development/root-tmo-vzw-intl-variants-soon-root-lg-t3164765. everything seemed to go well but after it was complete the phone wouldn't start and it booted only to a message on the LG LOGO with something failed. At that point I was still able to get to download mood so I tried to restore it to stock doing this : http://forum.xda-developers.com/g4/general/guide-lg-g4-stock-firmware-to-stock-kdz-t3107848. again the process went like it should but at the end the phone went dead with no signs of life, No led light, No vibration, can't turn on to anything and only gets detected on the computer as " qhsusb bulk ". My guess is I used the wrong KDZ files
I would appreciate it if you can help.
It indeed sounds like you have a hard brick, in which case the device can't be brought back to life.
However for chance, and for future reference. Which kdz did you try to flash? Assuming your device is the ATT model, then did you download the Puerto Rico kdz?
Because there is not a KDZ or TOT for the ATT H810 model the Puerto Rico KDZ from Claro will recover an ATT soft brick. These are labeled H810PR.

Maybe you downloaded the wrong img file from the first post? It has to not only match your phone, but ALSO match the version of the firmware you're currently running. That's why this method here is better:
http://forum.xda-developers.com/g4/general/lg-g4-100-root-success-directives-root-t3180586
Because you just make a backup img of your system partition and then inject root into that and you have a new rooted system partition img file along with your original system partition image file so you can go back to stock if you want some time later. I'm guessing you tried flashing the wrong version of your firmware. Do you know what version you were on? Looks like the only one listed on that thread is version g. I'm on version b, so if I were to have tried that, I would also have had an error when trying to boot. Had you made a backup of your original system partition as mentioned here you should have simply been able to dd it back and you'd be up and running. However now it looks like you've "hard bricked" your phone indeed. Out of curiosity, which KDZ file did you use? What's the file name that downloaded?
It looks like there are some utilities created that can UNBRICK some phones when they get into this state, but it looks like they have had custom scripts written for the partitions of those phones, for example:
https://www.youtube.com/watch?v=ERZvlJIC9dE
https://forums.oneplus.net/threads/solution-recover-from-hard-bricked-oneplus-one.104943/
Maybe someone familiar with how those apps run could modify that app for unbricking the G4s? Currently however, there doesn't seem to be anything you can currently do to immediately fix your phone. So ... can you get it exchanged or replaced????

Honestly, bring the phone to ATT and tell them it said an update was available, and upon accepting it...the phone ended up in this state. They will most likely exchange it for you.

not an option because I bought it from somebody on craigslist... I already bought another one so I'll just wait and see if somebody comes up with a solution if not I'll sell it for parts.

Any chance they can give you the original receipt and that way you could possibly send it in for warranty work.

Q - TOT file for H955?

Hi guys, I bought this phone and I'm really enjoying it, but had a problem last week. I soft bricked the phone and couldn't find any TOT firmware files for flashing, only KDZ and had that known problem being stuck at 9% when flashing the KDZ.
I've searched everywhere, but couldn't find a TOT firmware files. Arent there any firmware version for the European H955 in TOT file format?
I've sent my phone to the local LG service, and they've flashed it and brought the phone back to life. But still I'm feeling kind of insecure having no way to bring the phone back from dead when I'm trying or testing things.
So, question for you guys - did you came across a TOT file for the H955 of GF2?
Thanks for taking the time to read and answer...

BTW, how did U softbrick that?
Thx for reply. They did flash that for me. How I bricked it? I made a custom flash zip file with G4 apps and setting the permission for the system partition. Well, it didn't went well...
