[Q] [PROBLEM]Basaband/Network - Optimus One, P500, V Q&A, Help & Troubleshooting

Hi everyone, I've been looking at this forum for some time now to customize my P500
But recently I got the unlock code for my phone and to be able to put it I need to put it back to the original software, I tried allot of things, got the original software but can't get the baseband right, i've used lmdp to flash the old baseband back, flashed the whole rom with kdz but can't put it to work, I always check in the hidden menu the baseband version and it's always the new baseband amss6038, and got no network connection.
I've searched for a solution but can't seem to find it, if you can help me I'd really appreciate it

Maybe try the new baseband fix which temporarily flashes the old baseband and using it try unlocking......
Hit thanks if i helped you!!

You have to install the Indian froyo 2.2 rom from lg, and update from the Lg software, if it does not works, force it. It has worked at me

[Q] Any Roms That Have Baseband For G2x

Hey ppl! I've been having issues with my baseband after I flashed to stock from Eaglesblood 2.5. This has been going on for 3 days and I haven't found a solution that works. I'm trying to think outside the box here to see if I can resurrect my phone. Are there any roms that I could flash that have the baseband? Since I can't flash over to the stock Gingerbread anymore cause of issues I'm having with the software and/or drivers, maybe I was thinking I could use some other rom that perhaps has the baseband I need.
According to GetRIL the baseband I need is this:
M6600A-SCAUNTZ-2.0.9720T [Jul 15 2011 10:00:00] MP:TRULGE_08.09.02R_MDM
If there are any roms out there that have this baseband, please let me know and post a link so I can download. Thanks in advance. Any help you guys can give me to ease my suffering a bit is greatly appreciated.

Easy answer is, no there isn't a rom or anyway to flash the baseband... you will need to update through the lg updater.
Sent from my LG-P999 using xda premium
The lg updater doesnt work at all. It stalls at 4% and does nothing. I've used the kdz flash but the pc won't recognize my phone anymore when I'm in S/W Update Mode. I've tried using smartflashtool and that doesn't work either cause the phone needs to be in S/W Update Mode. So that being said, what other option do I have?
Send it in to LG, it's sad to see another user going thru what i had to as both lg updater and kdz are such shyt programs even with the correct drivers they buggy as hell. I love my G2x but hate the crap software LG and nvidia put out to try and fix these softbricks/unknown baseband problems. I wish Paul o Brian would have followed thru with his comment about creating a smartflash tool for our P-999's similar to the one he created for the P-990.
Yeah, I was reading about that. Even if he did I don't think it would work.
I used this debug tool here made by slycog:
http://forum.xda-developers.com/showthread.php?t=1248644&page=9
Paul gave up cause it would take him forever to get the smartflash for the baseband to work. First off, he would have to go and rewrite all the drivers so that they work properly. The guy in the thread above like me, had the drivers installed as you can see from one of the screen shots he posted. I tried 3 different sets of drivers all on my desktop and laptop. None of them work when I put my phone into S/W Update mode and connect the usb cable to the phone. As slycog discovered which I'm pretty sure he did but never said it that the driver for the modem just is buggy. Paul's first stop would be to rewrite this driver and get it to work properly. Then Paul would have to create the smartflash and actually get the smartflash to flash the CP bin file. The current smartflash for the P990 has issues flashing the CP bin file. It's alot of freaking work for a phone thats soon to be obsolete in a year or so. Makes no sense for someone like Paul to invest so much time into a project like this that the manufacturer (LG) should have done and foreseen. I'll tell you this much, this WILL be the last time I touch anything from LG period. I'll use my replacement for a month and then I'm off to Samsung. Hopefully by then the Galaxy Nexus will be on T-Mobile. If not, I'll get a GS2. In the meantime, I'll keep searching for solutions. I'm sure there is one out there or someone that can actually find a way to bypass the modem interface and use a different method of flashing per say thru APX that still seems to work for me. I wish nvflash was able to flash the baseband and I wish there were other roms that would have the baseband as I was informed none of the roms do.

[Q] flashed 4.0.4 stock rom, messed up IMEI

Hello everybody this is my first post on this site but it has be invaluable to me in the past for getting phones up and running.
I have a photon q that received a forced update to JB i rooted the phone put CWM on and flashed a stock 4.0.4 ROM to it (asanti_c-user-4.0.4-7.7.1Q-6_SPR-125_ASA-10-11-release-keys-Sprint-US )
Everything appeared to have worked correctly (IE it boots, i can access the internet/youtube app, receive gmail .etc) however the play store wasn’t working.
Fast forward 2 days of debugging and I realized that somehow my IMEI and MEID are messed up ( 0 and 00000000000000 respectively)
I have been looking at ways to restore the IMEI to the phone (i have to original number as it came on the screen protector when I bought the phone), however I cannot seem to find a method that will work with the photon Q.
Tried the terminal emulator method, After reboot nothing has changed.
Can’t find the /EFS folder (after looking that one up i do not believe it exists on this phone) so the method of manipulating the files within won’t work.
So the meat and potatoes of my question is how do i put my IMEI number back into my phone so I can use it again?
thank you in advance

Did you try using RSD Lite to flash the phone back to factory?
RSD lite
I Used RSD lite to flash the ROM.
As far as I know that rom is a factory/stock ROM.
If it is not where would I go about finding a factory ROM?

Ah, OK I was mistaken about how you flashed the device...
I'm not sure why that would or how it could erase your IMEI, I have used it many times.
That is why I am confused i have done this for other peoples phones prolly 20 or 30 times and I have never had an issue with it.
untill i go to do my own
So i need to figure out a way to put my IMEI back onto the phone. like i said i have the number i just dont know how to get it back into the device... :/
Still unable to find information on how to fix this.
I have however found out that there are three differant versions of the "stock" firmware for the same version and same model.
I am going to attempt to try them all and I will post results here.
FIXED
After looking the problem over i determined that my phone must have shipped with a different firmware than the "stock" one I had flashed. I found 2 other 4.0.4 firmware "stock" ROMS. they are all stock but some of them shipped on different devices. I guess with this phone you have to have the exact same "stock" firmware that came with it.
what I did
found and downloaded the other ROMS (will post the site to get them if I am allowed)
re-flashed the ROMS until one automagicaly had my IMEI number populated (i double checked against the number I had written down from when I got the phone and they are the same so it is not a "fake" IMEI)
I hope others who have this problem will find this helpful.

i mean that erasing imei is impossible on photon...simple question...is your phone switched to gsm mode?

Hi dude
I faced the same problem
Could you post the site to download roms?
Please help me

Bricked S6 please help

Hi guys
recently bought a s6 from ebay which was frozen on S6 logo. Basically managed to clear cache and factory reset from recovery but that didn't work, anyway I DL the O2 firmware and odin and put it into download mode I get a fail on odin when trying to install the rom
The phone has knox 1 and also has red writing SW Rev. Check Fail. Device: 3 Binary: 1.
I'm unsure what to do and if theres any chance for me to recover.
Many thanks
Mav
it failed because you flashed an incompatible Firmware.
where did it stopped flashing in odin? In sboot.bin?
If thats the case, you need to download proper firmware/country for your device.
Let me know what country is ur fone made of.
Hi thanks for your reply.
I managed to get it working by installing root and unikernel, it boots into O2 the firmwarw is 5.1.1
Only problem now is imei is 3500000000006
And it wont make calls dont know if imei is corrupt ir they sold me a stolen or lost phone?
I may install tw recovery and custom rom and see if that works.
Any suggestions?
Hi
Ive managed to sort out and get it to work infact typing on it now. Its currently rooted custom rom and twrp. I e managed also to restore original imei number so overall im quite pleased with myslef lol.
Anyway one last problem i have is ive tried all sims but none work i know ita picking up signal as the bar shows top right. Also chexk my settings.
Ive tried automatically and manually going to register networks but it says unable to connect try again later. I know uts not my area as my wifes s6 works perfectly. Sim also def works. The phone also picks up when a new sim has been inserted so i dont think its sim slot.
Any ideas guys
OK new update if anyone can help I'd really appreciate.
Installed new vador rom Imei reverted back and serial number is all zeros
Is this something to do with baseband if so how can I fix read somewhere about ariza patch but that was s3 4 etc.
Thanks
Mav
1. Your EFS is corrupted. The IMEI you see is a generic one, phone will be useless for network provider only wifi will work.
2. The one thing that caused this is by flashing an old bootloader to your phone. Thats why youve encountered Check Fail error on Download mode.
Happened to me also but got it fixed in the end.
OK thanks for the info how do I fix? I do have my wife's s6 but that's not rooted and don't want to root can I restore the efs
Many thanks
Mav
Been searching for ages can anyone please point me in the right direction for a fast download of stock o2 5.1 rom? I believe I may need this one G920F_O2U_G920FXXU2BOGC_G920FTEF2BOG1.zip at the moment rapid gator is going to take 10 hours lol.
Thanks

I think I know one thread that has a firmware downloader with ultra fast download speed you may try searching it.
I dont know if it will help, but you may be able to successfully flash the firmware but many of those who have problems were unable to boot the phone due to corrupted efs data.
Here's my way of fixing it (if you still have intact efs). http://forum.xda-developers.com/showpost.php?p=63693480&postcount=28
But if its already wiped, there's no way you can retrieve it unless bringing it to samsung or any repair shop.
Anyways, mine was fixed (IMEI) using Octopus box repair tool. Since I cant do anything to recover my generic imei.

As far as i know if your EFS partition is corrupt and you do not have a back up of the EFS partition to restore which you probably dont as you bought this as broken then sim capability is dead, im not sure of any other way to fix this unless you have the intact efs partition
Hi
How can I tell if the efs is corrupt it shows a baseband it now shows the correct ime I
It just won't connect to network it says try again.
I can post a screen print of efs folder on es Explorer if anyone knows what it should look like
Here are screen prints but I think I'm speaking to myself lol
Hi there i spent months on fixing issues like this (i now have a tool that takes care of all this) , best thing you can do is flash to a rom where the original imei came back do a backup of the efs, flash to a orginal rom ( latest rom) make sure its the right one for your device, connect to kies, install the rom again root and restore the efs failing that the imei is blocked use checkmend.com the uk version if your from the uk, message me if you need help

Your rom, recovery and kernel doesnt have to do with corrupted efs.
Only way is to bring it to repair service using box tools to re enter/validate your imei so that you can connect to your network provider. There is no other way around other than retrieving your efs and installing it or thru repair service.
You may now relax yourself at finding ways to connect, I assure it wont help trying to flash and flash and flash stuff to your phone.
---------- Post added at 08:46 AM ---------- Previous post was at 08:37 AM ----------
Uhm can you send sms or make calls? It seems you have a valid Imei
Ok ive tried all stock roms including o2 and a uk btu one but no luck they all do the same thing get frozen on Samsung logo then I flash unikernel and it boots.
When checking my efs folder I can see no modem file I'm now wondering could that be the fault? so I downloaded modem and BL for 5.02 and 5.11 both will not flash via odin I get a fail message and on device check fail device: 3 binary: 1 messgage in red?????.
So I'm a little lost, I was wondering if I managed to root my wifes s6 which is virtually new could I back up her efs folder then copy it into mine and just amend the imei to my original would that work? also is there a way of rooting my wifes phone without triggering knox?
Any other suggestions guys I really don't know what bootloader was on it to start with or rom is there any way for me to find this out?, also another weird thing when the o2 uk roms install they install german apps?
Thanks guys
Ive repaired EFS Partitions with scripts downloaded from links at xda.
For example i trashed my EFS partition on my note 3 so it caused hard reboots after android booted up and it couldnt be fixed with anything else than the EFS partition repair scripts.
Edit: friend repaired his Note 4 also.
Thanks but where can I find these scripts as I've looked everywhere and if I did find how do I go about doing it. At the moment when I try to flash modem and bootloader it fails.

In some real trouble, help please (G4 H810)

Hey, I am not sure if I am posting at the right place or should I create a new thread or not, really sorry if I am doing anything wrong, but I am in some real trouble here. I have At&t g4, it was on h81010g stock firmware version, it was working great and I was loving it but I wanted to update it to android 6, so I followed this guide https://forum.xda-developers.com/att-g4/general/lg-g4-h810-upgrade-to-android-6-0-t3323995 to update my version from 10g to 10o and then finally to android 6, 20o, (by the way its a great guide), everything worked fine but I have no signals, I tried to reset the phone and tried a few other things like hidden menu, airplane mode but nothing works,
I couldn't get the signals and shows a small cross above the signal bars, After that I used the LG UP tool to downgrade it to h81010o but still the same, I think my region don't have the upgrades further than h81010g or whatever the reason, I can't find the H81010g stock firmware anywhere, can anyone please share the original h81010g tot or KDZ file with me,
so I can get my phone back in a working state? a question for senior devs, bro if I can't get a h81010g file, what are my options then, any kind of help will be very much appreciated.
Thanks...

There's no other firmwares other than one ones I uploaded in my guide other than 21y which I'll upload in a few hours which was recently leaked (which is a shocker ). Also remember you MUST be on AT&T for OTA updates to work so that might explain why you cannot update via the phone.
I can't speak for that guide and not having service as I've never used it, you did perform a factory reset after doing that correct?
Did you attempt to try another SIM card in the device? And did you remove and reinsert the sim?
