I tried to update my G2x yesterday via the LG updater tool. Long story short, it froze on the S/W Updating screen and neither T-Mo or LG support could assist in getting it fixed.
I read that it was pretty hard to brick the G2x so I decided to give it an all out effort to resurrect it, especially after the T-Mobile tier two tech support told me there was nothing that could be done, if what he had tried didn't work, the phone was toast. I am just a woman who is more technical than the average woman my age, but I don't mod my phones much in general. I tweak.
I will list what all I have tried, as much in order as I can recall since starting this Friday at noon, don't laugh! (oh the phone is currently working, only 3g and with this Wind ancient looking version)
Flashed CWM on phone (tried all versions at some point in the process)
Totally cleared phone
Tried KDZ_FW_UPD_EN.exe to flash V21E_00 and V21Y_00 Neither would work
Flashed Cyanogenmod 7.1.0.1 Worked, looked beautiful, wifi but no cell service, no baseband, no IMEI
Flashed kdz WIND V11h - everything working but only at 3g
I thought if I got back to something that would put back in a baseband and my IMEI, I could find my way back to the most current update. I can't seem to flash anything new though.
I've tried this :http://forum.xda-developers.com/newthread.php?do=newthread&f=1149
and this : http://forum.xda-developers.com/showthread.php?p=25321356
Both awesome and helpful posts but I can't get anything other than this V11h!!
Help! And thanks! And I am sorry if this seems ridiculously easy, I think my brain quit working about 6 hours ago!
Oh, my question is, how do I go about getting it at least back to where it was? (Never updated from stock, March of 2011)

I'm by no means an expert -- an advanced amateur, maybe -- but I'll do my best.
What exactly were you trying to update when you bricked the phone? You said you were using the LG updater tool, but what exactly were you trying to do? Was your phone already rooted prior to the attempted update? Had you made any modifications to your phone or were you running stock? That may help us get to the root of your problem.
Are you still able to get into the S/W update screen using the directions in the PDF you attached? (Ie: if you remove the battery, hold both volume buttons, and then plug in the USB, does your phone turn on and go into software update mode?) If you can get it into this mode, you should be able to flash the stock TMobile ROM using NVFlasher as in this thread:
http://forum.xda-developers.com/showthread.php?t=1056847
This may get you back to step one, and you can try again. Or maybe at that point, someone more knowledgeable will come around with better advice.
Good luck.
Thanks for your quick reply!
I was trying to uh...update to 2.3.4 Gingerbread to hopefully help resolve some minor but longstanding issues I had had with my phone. Mainly, the random reboot and powering off I was really getting sick of.
My phone was not rooted prior to this. I was running stock.
Yes, I can still get into the S/W updater screen following the instructions in the .pdf I posted.
And funny you should post this thread: http://forum.xda-developers.com/show....php?t=1056847
That is where I originally started when my phone first froze. I have tried to flash to stock using the NV flasher right before I posted the original question. It didn't do a thing and that's when I threw my hands up and decided I needed help!

heh... I can totally relate to throwing your hands up. I just started tinkering with my phone a couple of months ago, and the first night, I spent from 10:00pm until about 5:00am just trying to get Cyanogenmod installed. It was frustrating, but after a lot of reading and re-trying, I finally got it to work.
Okay, when you run NVFlasher, do you get any messages at all? Once you click one of the buttons to flash the phone, I believe a DOS window should popup showing you the status of the flash, whether there are errors while flashing or if it completed successfully. If there are errors, be sure you have the proper APX driver installed, which should be included with the NVFlasher package. What OS are you using on your PC? Windows XP? 7? When you have the phone plugged into the USB and the S/W update screen is showing, you should see "'NVIDIA USB Boot-recovery" listed in your windows device manager.
lol...10pm to 5am eh? Sounds like me, I was (sounds crazy) noon Friday until 2am Sat and started up again around 9am and well...here I sit at 3 am my time, with a few breaks thrown in!
When I run NV flasher, it all goes smoothly. It looks totally complete, no errors. And I am familiar with the errors, the first few hours I had nothing but errors and dead ends. I have the proper APX driver for sure, I thankfully, run XP on this computer. And yes to the "'NVIDIA USB Boot-recovery" listed in your windows device manager. "
Scratching your head like me? I don't want to do Cyanogenmod again, which is what I am tempted to do, thinking now that I have the baseband back, the cell phone service would work. I really just want my phone back the way it was, albeit, updated..ok, so not exactly the way it was!
Currently on phone, so no links. But in other lg device forum on xda there is the "offline updater method" of kdz flashing. It tricks lg updater into using a custom kdz and not to check online. Look for v21y.kdz and use that. Its 2.3.4.
If you can get it working with the old wind mobile rom all you have to do is use the official lg tool from their website and it will update to the latest version for you I had the same problems you are talking about and the only thing I could get to work was the lg offline update tool and flashing the old wind mobile rom after i got that working just went to lg and used their program and it updated me to new baseband an 2.3.4.

This is what you will have to do. It took me a while to figure it out. But when you have the programs and files you need all downloaded and setup it works without being online. It worked for me once I figured it out. I had to read it a few times and do some searching for all the files but they are out there. If you do not find them via this site Google it. Good luck.

Awesome! What finally worked for you?
Hmmm...can I even remember?? My brain is still swimming in downloads and error messages!
I had tried the offline updater earlier, but the "Automatic Offline Procedure.vbs" file never would load, I kept getting an error on line 25. I downloaded it all again from other links, and this time I thought it would go through but I kept getting an error at line 70 something.
I finally read "instruction.docx" (the steps that the vbs file was going to have me follow) lol
I turned the windows enabler to the ON position.
I also disabled my LG modem first as I had read that on the .pdf file I posted earlier and it had allowed me to get Wind on there.
I disabled my firewall and anti virus temporarily also.
I opened the UpTestEX_mod2_marwin.exe set it to "3GQCT" and "EMERGENCY" and chose the V21y kdz
I hit "Normal web upgrade test"
Then start upgrade or something and the LG updater tool opened, it found my phone, I think I pressed Start upgrade or whatever again, waited, held my breath too long, passed out, woke up VOILA! DONE!
That is a VERY rough translation of what I did, I have had so many trial and error attempts and variations of settings, files etc, that I don't know what really finally worked! But thank you for your encouragement last night, because I was really about to give up for good (thus the last ditch "when all else fails ASK for help" post) and throw not only my hands up, but the phone across the room!
Now I am finally getting around to re loading my apps and all my settings, ringtones, etc etc etc. I don't know if I now love or hate my G2x!
Thanks to everyone for their replies! And everyone else who posts here and helps so many novices like me!
Glad to hear your back up and running.

I have literally tried everything I could possibly think of to get v11h updated to v21e or even v21y and nothing is working for me. I am stuck at the part where the phone begins to update, but disconnects at param(5) and then fails after that. I have tried every method and tutorial that I could find and I am still searching. Any help would be most appreciated. Thanks!

What does "disabling the LG modem" mean?
I have a Wind P999 phone with the V11h base band. Of course, the LG updater tool says that I have the latest baseband.
I tried updating using the KDZ tool but that did not work. for me.
I tried pushing a T-mobile Stock Rom too. It did not updated the baseband. LG tool still says I have the latest update.
I have also tried the hack of using the LG Updated with a local shttp server. But even then, when I pressed the "Normal web upgrade test" and "Start update" nothing happens.
Am I supposed to get some feedback while the upgrade happens? How long does this process take?
I am using Window 7 Ultimate 64-bit. All antivirus disabled.
Anything else I could try?
BTW, I have been able to revive a bricked p999 T-Mobile phone that I got from Ebay. it has the stock T-MObile Rom with the March 2012 baseband and software version v21y. This Wind phone is just testing me
Ok, I have a phone that I purchased used. When my S3 got the Jellybean update in December, I found out it had Clockwork Recovery Mod installed on it. It scared the hell out of me, but I went ahead with the update and it was fine. I am a complete newb to rooting and would never root my phone (I lack the skills). When the update went through in December, I was relieved. For more details on all that, see this thread: http://forum.xda-developers.com/showthread.php?t=2048805
Today's update was a different story. This update appears to have broken my phone.This time, it won't even boot up. It just say "System software not authorized by Verizon Wireless has been found on your phone and go to the nearest Verizon Wireless Store for help." Any suggestions on how to fix this? Am I completely screwed? I have almost no knowledge of rooting, ODIN, etc.

The weirdest thing just happened. Ok, I put in ODIN mode and pressed cancel. Then like 3 minutes later, it just started up all on its own. The update failed of course but the phone is working again. Weird. Was able to turn it off and restart.
I think I may trade this phone back into the same folks who sold it to me. I am clearly not cut out for this.
i'm glad the problem solved by itself
anyway if you still want to attempt to reset the phone to stock here is everything you should need to know :

let us know how it went and don't hesitate to ask for help if you are still in doubt after reading the forum
I hate how I am average Joe with my root knowledge and I could fix your phone without thinking twice.
It surprises me you have an xda account and can not even root and unlock boot loader.
You ask for help then say. Never mind.

I recently tried to root my D850 with 5.0.1 Of course, I botched it and it got stuck at the boot screen. I figured a factory reset (hard reset) might save the day, but it didn't. The device was not recognized by the PC and the MTP driver would not work no matter what I did. In desperation, I chatted with an LG USA rep. He said to submit a repair request, which I did. There was no mention of cost but at this point, I don't care if it does cost to fix it. They emailed me a FedEx label and I sent it off yesterday. There was another thread in which the OP sent his in to LG with pretty much the same thing happened and his device was repaired free, so I'm hoping for a free fix. Point is: I got this device from a seller on eBay and I was upfront with LG about that. Warranty or not, they seem willing to fix it for me. So, instead of beating your head against the wall trying to fix it, you might want to consider sending it to LG if you get it fixed yourself.

Then try another PC.
Sending to the company is a last resort type thing. Some cases people have been charged more than you can get a used one for at times.
The method in that thread is the exact way LG will be fixing your phone. (Unless they just replace your motherboard)

If that's the exact way and it works for them, GOOD! Because I tried it and several other methods and it DID NOT WORK. As the person the said in another thread, they fixed it FREE. And, if they charge me, so what? I'll have my device working properly. I don't know where you'd get one of these for under $100, but if they fail to restore it, please DO tell me as I'd sure like to know. In fact, tell me now so I can grab one for my wife.

They normally at least charge $200 + for a phone repair. . I've dealt with LG and LG phones for a good while now.
And not sure if you have ever posted in my guide asking for help.
Different methods? There's ONLY ONE method that works for the D850 which is the TOT method.
After downloading and installing the drivers , software and zipped tot, did you make sure phone was IN download mode? Did you make sure you changed your COM port to COM41?
You have to be sure your following everything step by step.
The guide is very simple. I can pretty much gurentee that if you lived nearby I'd have that phone fixed in under 20min.
I'm just stating myself and my guide has fixed 1,000s of LG phones.

Maybe so, but it didn't fix mine. See, when the PC does not see it, nothing is going to download, upload, flash. It's a moot point anyways, as it's on it's way to LG, Ft. Worth.

Wishing you the best of luck, Provide and update as to what happens.
SO the phone was in download mode when you tried? You`d look for LGEmodem under ports in device manager.
UPDATE
So, I sent my G3 into LG_Ft. Worth approximately a week-and-a-half ago for the symptoms sited at the beginning of the thread. Bear in mind, I got this phone from eBay and I told them that. I also told them that after I tried to do a Factory Reset, it locked at the LG boot screen. That's ALL I told them. No questions asked: They sent me a replacement unit. F R E E!
The invoice stated "Bad ROM flash. Replacement sent." I'm restoring from back-up now.
Same issue as OP
I have one G3 soft bricked. At first, i was be able to connect to dl mode. I tried LG Mobile Support tool to flash the phone back to stock , at the end, it failed. Now the phone not let me enter dl or recovery mode. PC not detect the phone at all. I'm using original Nokia USB cable. Tried with 3 computers, none of them detect when plugin and hold Vol up or down etc...
I want to follow TOT method but what can i do if computer not detect the phone?

I'm sure there will be others that will have you try different things, but FOR ME, I went to the LG website and chatted with a tech. He told me to send it in. Even provided a shipping label.

Yeah but using my back to stock guide can take about an hour depending on your connection. If connection is good then maybe 20 min.
And not all cases will be the same. There's some cases of people getting charged even just to get there phone back.

Sorry for the delay in case you didn't find out no, the method uses official lg firmwares. Which requires windows. So no way to do it on a Mac unless you use a virtual machine which is very buggy to do this with.

On the topic of bricking (and unbricking !!) the D850, I just received a D850 from ebay today. I tried hyelton's procedure
to restore a stock ROM (LGD850AT-01-V10d-310-410-JUN-19-2014+0.tot) and it failed during the download.
My D850 entered a horrible bricked state, booting with a "secure booting error" message, and then alternating with red and blue LEDs. It was impossible to enter download mode. Trying to use the default recovery to do a factory reset failed. Basically it seemed like the device was bricked.
I was a little panicky because I just received the phone earlier in the day.
I then found this amazing thread on the Sprint LG G3 forum, which describes a sort of hard reset you can do inside the phone. (kind of like an alternative download mode to transfer files to the device). This requires you to short two connections in the phone with a ~2cm piece of copper wire, so you obviously need to be comfortable disassembling your phone.
http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359
I am happy to report that this procedure worked perfectly to return my ATT D850 back to life, notably giving me download mode back, which I used following Hyelton's procedure to download a stock ROM back into the phone, which now worked fine.
I hope others can benefit from this.

No Fixes Yet. Tried Hooking Up To A Windows 7 Machine. It Keeps Switching Between the LG Drivers & VZW Drivers For The Phone.. Going to try using only LG Drivers. Be Back with hopeful results
Just wanted to update that I received phone back from LG all fixed.
I'm new to the XDA Forums and even forums in general so if I speak out of place or anything like that I apologize ahead of time. So anyway, where do I start? I'll try to give you the short version. So I bought an LG Stylo 2(model: LG K540) through Cricket the day they came out. It was $170 phone. On the second day of using my new phone I got the bright idea that I'd try and root it BY MYSELF. I knew better but for some reason I had this false burst of confidence & thought I had everything under control. Well, thanks to Kingroot that burst of confidence didn't last long and there I was with a 2 day old phone BRICKED. Reason I never posted on the forums is because I've got a buddy who , in my eyes, knows everything there is to know about Android and thats who I'd normally go to when I wanted to root a phone so he's who I immediately turned to but even he couldn't figure it out. He couldn't help me unless we had the stock firmware or someone with the exact same phone and according to him we could some how use a backup of that phone to fix mine. Cricket just wanted to sell me another phone even though I was standing there with a 2 day old phone and LG just wants me to send the phone in to them, which I have no desire to do. I've searched all over the internet trying to locate the firmware because even I can fix the phone if I had that but nothing. Had hoped by now LG would have released the firmware but at this point who knows when that'll happen. I'd even pay for it at this point. Anyway, just thought I'd give the forum a shot on the off chance someone might be able to help me or point me in the right direction. Oh and if you were wondering what the phone does now, when I turn it on the LG logo appears like it should but then right as it appears you see a message in red lettering that says: BOOT VERIFICATION FAIL!!- CAUSE: MISMATCH_SIG_LEN And it just loops this over & over until you pull the battery out. Please someone help me!
send to lg said stop working no luck with tihs hard brick
Source code to rom¿?
I ran into basically the same situation as you. I'm currently downloading Android open source project on to a fresh install Ubuntu 16.04. I am currently in the middle of running sync.
I'm curious if there is anybody out there who would be willing to give a few pointers, on compiling the ROM from LG open source code. They told me I had to use it in the readme.txt.
Im a noob with fair knowledge of modding and stylo not stylo 2. There's no way to say for sure if this will work but on lg mm on h631 u need to unlock dev option in settings 1st. Make sure to check off oem unlock and usb debugging. Connect to pc and you will get a popup or 2, one will ask to allow pc to connect to phone, the second is to allow usb debugging. After you allow both, open cmd in your adb fastboot folder. Type " adb reboot bootloader." should reboot the phone to bootloader/fastboot mode. Then you type " fastboot oem unlock." you will see sending.. Once sending is done type " fastboot reboot." when the phone restart you should see bootloader unlocked on splash screen. Then i rooted with kingroot. Then use rashr to flash twrp. Then used twrp to flash supersu to get rid of kingroot.. My h631 now in business and i just started working on a port for lg ux 5.0. This is the guild i use for a better idea http://forum.xda-developers.com/lg-g-stylo/how-to/guide-lg-g-stylo-how-to-root-t-mobile-6-t3333916. You might need lgflashtool and kdz to unbrick..
NO NEED to beg.
I don't know very much but I know $$$ talks and since no one save the few who suggested contacting lg wants to help, Ill try. At the moment I am efforting a solution via the Chinese. I expect to have a working copy in the next 48hrs. when I do, we can arrange for you to get access to the mega.nz cloud and get urs.
say a prayer......

BIN File
Hello, I have a Stylo 2 K540 from cricket, it is having issues with the Wi-Fi, it will not connect to either Wi-Fi or bluetooth, MAC address was set at 02:00:00:00:00 or something like that, I opened the phone and it has humidity sensor active, cleaned the affected area but it seems like it was useless, eventhough I was pretty sure that was not the main problem. I looked for some troubleshooting options and found non of use, firmware is sold for $30 online so it is not an option since I am not certain loading firmware will be of any help. I tried repairing MAC address via Octoplus using other addresses but was useless as well.
I have little to no experience with software on phones, but I like to read and learn. I decided to connect the phone to the computer and "Read full flash" on Octopus, I have created the Bin file, I have a perfectly working phone as well, I was wondering if there is any way to get the KDZ file from the Bin file doing some sort of conversion, or if I could do some sort of fix or workaround with this bin file, I can share it if anybody needs it or if it can be of any use to get the firmware

I'm new to the XDA Forums and even forums in general so if I speak out of place or anything like that I apologize ahead of time. So anyway, where do I start? I'll try to give you the short version. So I bought an LG Stylo 2(model: LG K540) through Cricket the day they came out. It was $170 phone. On the second day of using my new phone I got the bright idea that I'd try and root it BY MYSELF. I knew better but for some reason I had this false burst of confidence & thought I had everything under control. Well, thanks to Kingroot that burst of confidence didn't last long and there I was with a 2 day old phone BRICKED. Reason I never posted on the forums is because I've got a buddy who , in my eyes, knows everything there is to know about Android and thats who I'd normally go to when I wanted to root a phone so he's who I immediately turned to but even he couldn't figure it out.
