I am sick to my stomach. I tried to update my WIND version of the G2X to the T-Mobile V21E_00.kdz to get the newer baseband installed but it caused my phone to get stuck at "S/W upgrade Please wait while upgrading..." and the V21E_00.kdz
file I downloaded is corrupted (I've downloaded a few from various sources). I did do the NVFlash recovery and installed ClockworkMod Recovery before I did that but nothing I've tried, and I've tried virtually everything to resurrect my LG-P999 phone, worked. Various flashers I've used stop at extracting the V21E_00.kdz because it is corrupted. The normal LG update tool that is used for the T-Mobile G2X doesn't work for the WIND Mobile phone version because it detects that it isn't a T-Mobile phone and won't install the update and won't do an emergency repair. This phone can't be returned to WIND or LG because the upgrade I tried is "unauthorized" and they won't help.
Does anyone here know where I can get a good copy of V21E_00.kdz which will fully extract and, if you do, please post the link to it.
Is your phone the T mobile version?

Why don't you ask here:
http://forum.xda-developers.com/forumdisplay.php?f=1114
Your phone is a p999 if I understood correctly.
I think you should use nvflash to restore a proper system, it always work. Ask in p999 forums.

Hi Core Memory, I don't know if you finally got an answer to your problem, but I got stock in similar situation, T-Mobile G2X that no longer boot after doing a LG update,
tried the various ClockworkMod Recovery, nvflash, root, nandroid, img, fixes,
but ended with that procedure as last resort, which failed with the various files I tried. same corrupted error message while extracting...
In my case, the error message was misleading,
I finally notice that the file I tried were containing a space: 'P999 V21E_00.kdz' apparently those kind of tool can be picky, I just try removing the space in the name P999_V21E_00.kdz
My guess was right, I restarted the procedure and everything went fine,
the phone is now up and running, using Gingerbread (2.3.4 I think)
hope this can help,
Jonathan

Thanks for your help.
I did get the problem solved a long time ago and have learned a lot since those early days of owning the G2X. The V21E kdz file installs Gingerbread 2.3.3.
Hi everyone, I really need your help. I have basically bricked my phone but it is not beyond hope as some things seem to be working.
What I did:
I used ROM Manager to boot into a boot screen. I was very turned around and confused and I did not have Clockwork Mod on my CM9 phone, as I thought and I'm really not sure why I thought this was the right thing.... In that boot screen I flashed a TWRP recovery file (http://goo.im/devs/tonyp/P990-stuff/TWRP).
What happens now:
I get a white logo and then the phone turns "on" but on is only a white logo with a little splash of purple behind it (like 2cm long). This "on" state the touchscreen is sensitive insofar as if you touch it when it dims the brightness will jump back up again. That's it though. If I plug the phone into the computer (win7) the pc will ding ding and sometimes it says it installed properly, sometimes not, either way it does not show up in My Computer as a device. If I run SmartFlasher on the pc and plug the phone in (in S/W Upgrade mode which it appears able to do), SmartFlasher will detect the COM Port.
What I already tried:
I tried to use SmartFlasher to flash a stock ROM I found (http://www.modaco.com/topic/350555-lg-optimus-2x-stock-rom-update/) but I received a very non-helpful error that just says "type mismatch error". I tried another file, can't remember what it was or where I found it, but I got the mismatch error also. I also tried to update the phone via the LG Mobile Tool. It finds the phone, installs drivers, etc, even lets me open the update thing but then during the process it says it can not communicate with the phone and it is aborted.
Any ideas?? I can't afford a new/used phone... There must be some way to salvage this...?
Use this tool to solve your problems http://forum.xda-developers.com/showthread.php?t=2020737 ..... And as you have the old bootloader, so make sure you flash all files for old bootloader only and not new one....
And also make sure to read the instructions given in tool manual...

Thank you! I will do this in a few hours on my break and see where I get
Ok...so I had to do a LOT of stuff w/n that tool that did not work before I managed to get anywhere...but I got somewhere! yay!!
The phone now boots into TWRP v2.5.0.0. The next step is to flash a ROM because there is no o/s installed. Before I go any further I'd like to know, should I use the stock ROM or should I use the files from ParanoidAndroid 2.6 (http://forum.xda-developers.com/showthread.php?t=2097807 -- the link you gave me the other day).
Stock ROM sucks..... Use Paranoid Android... You won't regret it ...

Unfortunately more problems lol I was able to get it on there without problem. However I can not connect to my cell provider. The APN listing is blank and even if I manually enter and select save it does not save it, the list stays blank.
So, next I tried the most stable release of CM just to get this f'ing thing working. It went through and said it was successful but when I boot the phone up it is still Paranoid Android...which I don't mind except the APNs are still blank and my phone is still useless.
Any idea what I should do next? I tried searching for this APN problem and I tried two APN apps from marketplace, neither worked. I think the solution is to clear the phone and do another flash but that does not seem to be working...
If I remember correctly, some people had this APN problem but I NEVER had it... They solved it by manually inputting the APN... But seems you are having some weird problems as it doesn't even save the APN.... Try again inputting APN manually and save it properly ..... If it doesn't save then try CM 10.1 from link I gave earlier.... That is also a cooooool and smoooooth ROM with many more features ....
And make sure you install a new ROM only after a full wipe and also system format after taking backups of your apps, etc obviously ....

When I tried to install the newest stable CM I did do a full wipe (according to the TWRP v2.5 ). That's why I don't know what to do now. I can't seem to get Paranoid Android off / change to a different ROM.
Any ideas?
Okay so I have put 3 different versions on now and they all look and work great...except no cell connection, no apn's. I saw some people fix this by replacing their BB via smartflash but I can not do that because I get timeout errors. Smartflash doesn't work at all. Neither does the LG Update tool from w/n that toolkit. The only thing that does work is flashing zip from sd card and changing the recovery image via adb in that toolkit. I can not find any methods of replacing the BB except via Smartflash.
If you get timeout errors in smartflash, then do this trick.... When you click "Start" in smartflash and the flashing process starts then immediately pull the battery back inside phone and then you shouldn't get timeout errors ..... This always works for me.....

I live in Canada, my provider is Wind Mobile. This was originally a T-Mobile phone from the US. I bought it used, it was unlocked and running an older version of CM. The actual model number is P999DW
For convenience I just want to recap the issue:
I'm open to ALL ideas! On the all in one toolkit that I downloaded from the first reply only a few options work. The LG Update Tool and Smartflash...whether using them via the AIO toolkit or just using them independently always error out with some sort of communication based error. I can repartition and change the recovery image but that seems to be the only options that work from AIO toolkit. My understanding of the problem is that there is no, or an incorrect baseband file. The phone is behaving almost like a tablet. It won't search for networks and it doesn't even give me a SIM error, it's just not looking for it at all. I have formatted sys and repartitioned and wiped and re-flashed several different ROMs (Paranoid Android, stable CM, tonyp CM 10.1, etc) but this problem remains.
What? Do u have a P999? I'm not sure, but I don't think that P990 ROM will work correctly on it... In fact it shouldn't even install as the updater script checks whether the phone is P990 or not.... And if it isn't then it should show error and not flash the ROM... Did you change the updater script line to P999 instead of P990 to make it work...

I didn't do anything different. The P999 is just the T-mobile version and P990 is the International/Rogers/etc version. It was previously running CM so I don't really think that is the problem. http://forum.cyanogenmod.org/topic/37457-p999-vs-p990/ The only errors I am getting are communication errors between the PC and the phone...not version related errors.
I would happily put the stock P999DW kdz file on if I could but the only method I know to do that (LG Update Tool via that AIO toolkit) does not work because it is timing out.
Okay so everything on my phone before and also now says it is an Optimus 2X. I started searching after your last comment and does this mean I have a Optimus G2X? F'd up...even the battery says it is a P990 Optimus 2X. Gonna see if I can find any NVflash ROMs for that one since nvflash method is working.
Use this link to download latest Official firmware for your phone
http://csmg.lgmobile.com:9002/csmg/b2c/client/auth_model_check2.jsp?esn=[IMEI]
Replace [IMEI] with your IMEI in the link...
OR
Download firmware from here ... It also gives list of official links .... There are P990, P999, SU660,P990HN firmwares with different countries listed...
http://lg-phone-firmware.com/index.php?id_mod=3
Try to flash it as KDZ (or) extract .bin & .fls files from it using AIO Toolkit and then Smartflash those two files ... If you want to flash only baseband then .fls one is the baseband ....
I'm telling to do this because it may be possible that you are trying to flash wrong KDZ or wrong baseband and that's why, may be, you are not able to do it ....
If you flash v30 firmware then your bootloader will, most probably, be changed to new one .... So consider that in mind also before flashing .....
Or a better solution ..... Natalya said that he/she might be knowing the solution to your problem... So try to consult for that also....
Again, there is a dedicated development for P999 also on CyanogenMod apart from P990 http://get.cm/?device=p999 ...

You just got a bit ahead of me in writing this comment ... I couldn't see it before writing my reply .... So one of the methods for confirming your phone is to look beneath your phone battery on the phone and another is to go to the first link I gave above and insert your IMEI also there in the link and then see what firmware download link LG returns .... Phone model will be also written in the download link, so you can check there also....
Hey guys,
So I had this problem with my 4x because of rooting it there was no baseband atleast it was unkown. I followed a guide but that didn't help. I tried Lg Flash Tool but that gives me a Download error after some seconds. Then I tried putting back the orginal KDZ but it says everything worked but the phone won't reboot like it should. Waited 20 mins to do something.
Running Windows 8 64x
I have no idea what to do now, please help.

Whenever I try Flash Tool it gives me a Download Fail with error code 210? Help please.
try to change the phonemode on software update(KDZ) from DIAG to EMERGENCY. that saved me a week ago .i had the same problem
Similar Problem...HELP
Hello, I seem to be having a similar problem. I tried KDZ, as per the flashing tools page, but after running the KDZ unpacking and then it stops at paramenter 210. The phone screen stays at S/W Upgrade, and nothing else happens. The KDZ log stays at parameter 210, and goes no further. I am following all the exact steps. Also in the KDZ Phone Information link/Button, no info shows up about Phone, meaning all fields are blank. Back ground Information: i had before a CUSTOM ROm 4.4+ & later 5.0+ installed, but somehow after some time, my phone stopped recognising any SIMs. Android would work but no Sim was working. I thought it was a hardware defect, but later i checked in Settings> Status, there was no IMEI showing. Something had messed up, I read up that reinstalling the stock ROM may solve the issue, so i tried it. But all i have now is that a phone that doesnt boot up, always shows S/W Update screen. And with KDZ only goes up till parameter 210 (in software status log) and doesent go further. Tried all DIAG/Emergency etc. Is my phone bricked or is there a solution ? Please HELP ..... Any help/suggestion appreciated. Thx

I searched around and found that this phone had a system update that didn't complete correctly and now is stuck like this. I have no idea how to fix it though. I tried the "Flash Stock KDZ Offline LG L90" process, which was apparently successful but it didn't change what is happening.
Notes:
* If I restart with power+volume down it goes to the factory data reset page, but when I select yes it just does the reset, so no recovery is installed.
* If I hold volume up and plug in USB I can get to the software upgrade screen, that's how I did the KDZ flash. Can I do anything from that screen?
Please let me know, or point me in the direction of useful posts. I haven't done anything like this in a couple of years, so I'm a little out of the loop on most things.
Another Note:
On the Firmware Update screen there's a box at the bottom that says:
USER B40

I had no responses to this in any of the forums I posted in. I tried everything I could think of and eventually just contacted LG support. They took the phone in and yesterday I got it back. Looks like they switched it out for a new one, and the problem is obviously solved.
Not a very XDA solution, but an effective one nevertheless.

because, when I flashed new KDZ it again boots into the same ..
I am trying to get adb access,
If I got the access I can remove laf.img so i can enter into fastboot mode. where I can flash rom/ recovery
otherwise wiping cache and fota partition might work...
still doing some experiments..
But in G2 forums,
one member mentioned that it can't solved until u go to LG service..
but I saw some guides in G2 to unbrick ..
I'll try....
The notes from the repair said something about a "bad language" and that they replaced the motherboard.
It's definitely a new phone though, there were scuffs on the corners of the one I sent in that are not there now, it's scratch free!
i was freezing and uninstalling apps last night and must have removed something critical to the operating system. Now my phone will only load the Security Error screen with (authetication failure) in small print. i've been told that my phone isn't bricked but that i need to reflash the image.

I believe I used 10g instead of 10i version (which I downloaded from the root-tmo-vzw-intl-variants-soon-root-lg-t3164765 page at xda-developers.com/g4/orig-development/), but now cannot seem to use any of the recovery methods because I do not know how to push the proper [system.img] file to the root directory. I can get to the "Firmware Update" screen but the hard reset function does not appear to work.
Can anyone help?
Hey hey i'm also having an authetication error with my LG G4 on sprint. I HAVE NO CLUE WHAT TO DO THO. Sorry for the caps i'm seriously freaking out because no where on my phone in the settings could i find out if it was LS991Zv4 or Zv5 or whatever i was so i used the method that seemed to work for most people and now i'm just sitting here crying because i just GOT this damn phone ;w;
i can't find a KDZ file for my phone anywhere ;w;
and the TOT file requires me to log in to the LG Flash tool? I'm so confused ;w; rooting motorola devices back in the day wasn't as troublesome as this ;w;

Download LG Flashtool zip, install LG Flashtool ( dont open the program) in the unzipped files copy paste mega.dll, copy this file to C:\LG\LGFlashTool and replace de original file... after that Run the program and you was to able to flash TOT file
Also stuck
Hi, saw you helping a lot of people. Hope I can be next, lol. I'm attempting to repair a botched root attempt on H8110. Apparently, the first rooted image was not the correct one. The phone is stuck in a boot loop with "Security Error". I can get into download mode, but can no longer USB copy the correct image over. What steps can I take to get back on track? Thank you!

Help meeeee
My phone won't even really turn on, the welcome screen comes up and says that there's a security error, and stays on that screen. I don't want to do a hard reset if I don't have to

Well you're gonna have to use LGUP to restore using the TOT.

Hey, could you share your solution here, not as a "cure-all" but just for an idea..?

The new LG Bridge tool doesn't work and the old LG Mobile Support tool does not work on the G4.
