WOW!

Geeze... spent hours trying to unbrick this thing to no avail. HAD to create an account just to thank you!

Long story short: I bricked my phone when trying to go completely back to stock, from totally modded/hacked buttery goodness, in order to update to v21y. Aside from giving you a huge ":good:" and virtual :highfive:, I also wanted to say/reiterate some things for anyone else that might be in my same situation:

He really wasn't kidding... THIS DOES NOT WORK IN ANYTHING OTHER THAN WINDOWS XP! (I used "Virtual Box" so as to not have to dual boot).

I found out something interesting... after following this guide and bricking the phone (totally my own stupidity). I installed Windows XP in Virtual Box, and ran *your* guide, but used "V21Y_00.kdz" instead of "V21E_00.kdz". Instead of "CDMA", I set the "Type" to "3GQCT", and "Phone Mode" to "EMERGENCY".

Everything worked like a charm, and basically everything went down exactly like you said, except for the aforementioned changes to the steps (even the prompts / messages in the updater look the same).

ALSO: If you use Virtual Box and not something else (like VMWare, or whatever) I noticed that when the USB starts disconnecting, it won't reconnect to your virtual machine until you go to "Devices -> USB Devices ->" and click on your phone. Gotta do the same when plugging your phone in for the first time in "APX mode".

So you really gotta be on the ball and reconnect it to the VM quickly, before it times out and you have to start all over again (had to redo this guide a couple of times because I wasn't fast enough).

So your method basically ended up both unbricking my phone and installed the baseband upgrade I wanted!!! So CHEERS! :)

Links need to be updated, my girl's phone is bricked. I can't access recovery and the phone is stuck on a grim reaper android screen, the android is holding a death scythe. Please help, I'm freaking out! If I don't get this fixed, I owe her a new phone today
[T-Mobile LG G2x] djvoleur:
NVFlash ROM and then NVFlash CWM 5.0.20...then you will be able to access recovery and install whatever ROM you want to install...
[T-Mobile LG G2x] leolawliet:
Thanks :D
[T-Mobile LG G2x] leolawliet:
Worked flawlessly, she's really happy with CM7. Thanks again, I really appreciate the help dude ^_^

What roms should I have her check out?
[T-Mobile LG G2x] TMOfo:
I forgot to say thanks, I thought I bricked my phone for good and was ready to buy a new one some time back. I appreciate this, especially for the fact that at the time I didnt have the money to buy a new phone.
[T-Mobile LG G2x] austinlblanton:
Whenever I try to flash back to stock it says waiting for bootloader to initialize. I can't get it to do anything else. The phone doesn't turn on at all and only goes into APX mode.
[T-Mobile LG G2x] buru898:
Flash back using nvflash? Try using a different USB and different USB ports on your computer.

When the phone goes into S/W Upgrade mode and I plug the USB back in. Windows does not load drivers so phone is not connected :(
[T-Mobile LG G2x] churd83:
I just wanted to say thank you for getting my phone back up and running after failing a baseband downgrade.

I also wanted to note that if anyone is having trouble getting winxp setup for vmware or virtualpc you can get windows XP mode straight from Microsoft's website and use either virtual PC or vmware to run it.

I say this cause I couldn't get windows XP to install in vmware without having a product key, even with integrated version.

And also using the v21e kdz got me July baseband so now I can use my Bluetooth in cm7 now!

---------- Post added at 02:43 PM ---------- Previous post was at 02:33 PM ----------

And also a note: couldn't get nvflasher to work on winxp. Don't know why but it failed to open. Just flashed stock recovery in win7 first then followed the next steps in winxp.

Also if your not sure if the program is running or not go open c:\user\documents and settings\shared documents\application data\(some LG folder,forgot name not at home)\

Application data folder is hidden by default. Must go to folder options and enable show hidden files and folders.

In this folder you can see it writing files to the folder for use in flashing to phone. Guess its temp? Either way its good to look at if ur not sure if the app is doing anything or not.
[T-Mobile LG G2x] Sentinel604:
I know this is an old thread but my phone is bricked and I want to get things up and running again

Does anybody have the V21E_00.kdz file somewhere? All the links are broken including other threads on this forum as well (yes i've tried google already)

:eek:

Bricked

I have a bricked G2X (LG-P999DW) that got bricked using the LGMobile Support tool. I am able to install the APX driver, but as it says in the below log, when I try to flash the ROM I get a "vError 0x30012 command failure: bootloader download failed" error. I've repeated many times with the same result.

Thanks for any help you may be able to provide.

Screwed.

Didn't work for me. I have no signal, no battery stats and no IMEI. So, I have no baseband. That's why I'm trying to flash the stock firmware by another way than nvflash (because nvflash didn't flash the BB neither)

The program freezes out just when I click on Launch Software Update, without showing anything on the log. It could stay hours connected (because I left the device HOURS connected), and nothing happens.

When I unplug the cellphone, the program de-freezes itself and obviously fails on the flashing.

I tried this, and similar methods, and nothing yet. Six entire days with this s...

Please, help me if you know how.

Hello guys ... am new here in this forum ...

I have a problem with my lg p999 wind mobile canada phone .... i tried to do a firmware upgrade from froyo directly to jellybean 4.2.2 but in rebooting after flashing the rom it got stuck with the lg logo and i tried so many things but didn't work out including trying to hard reset it in pushing the power + lower volume together but didn't work out went back to lg logo again n again ....

I tried the nvflash said it can't dectect the usb port even though np with the port ... tried the smart flash tool and i couldn't find the v11h firmware to put it back .... tried the new one v21y and it said the magic number does not coincide ... tried also the lg mobile tool to try to fix it but again it said fatal error in trying to update the firmware software.

Any help would be much appreciated ... Thank you in advance !

Hi all...

I was watching, reading and was excited about cm 14.1 for my LG g2 which was running on lollypop.

What a mess I created for myself. Will explain step by step. I I would be thankful if anyone can teach me get out with it and back to LG rom lollypop.

1. I rooted my phone with one click tool.

2. Then I installed Twrp through play store app.

3. Download cm 14.1 for lg g2. The as well as open gaps.

4. Next thing I did rebooted to twrp recovery and clean it after taking back up. But was not able to flash cm 14.1. Also loaded gapps7. 1.

5. After so many trials nothing happened I even updated twrp to 2.8

6. Then I found twrp 3.0 and tried to flash it.

7. Suddenly my phone came to a stage Fastboot.

8. My computer stopped detecting it.

9. Then I re plugged it into the USB of my computer.

10. I found the partitions are there. But no system is there.

11. Even I don't know to sideload it.

12. Lg flash tool is not able to flash it.

I request if someone know the way to flash it with lg roam. I L be thankful.

Can anyone email me steps to do to get out of it.

My email is optionstyles@gmail.com

Thanks

Qball,

Sounds like you have not successfully installed the USB drivers for LG on your non-Windows7 pc. Get the download for the LG installer, you probably already have it because you are stuck in the S/W Update screen. Install the LG updater and then run it WITHOUT the phone connected and select the download USB button. Let the drivers download and then close the updater.

Now go back to the kdz installer and get it started. Plug your phone into the USB and wait for the installing drivers popup to appear, and then monitor until the drivers are configured. The drivers may take several minutes to install, not sure why but they install very slowly. Once the drivers are configured, you should be able to complete the kdz process.

Good luck,

Steve
[T-Mobile LG G2x] chimchim54321:
Chris, be patient while the drivers configure after hooking up your phone. They load really slowly for some reason.
[T-Mobile LG G2x] Qballdz:
How long approx? This might be my problem. When I hook up my phone right before I start KDZ it says loading drivers by the clock icon on the windows task bar. But it never says Hardware Ready For Use. The only time that message comes up is after 5 minutes when I get frustrated and pull the USB cable.
[T-Mobile LG G2x] chimchim54321:
5 minutes could be correct. When the icon comes up on the task bar, click it to open and watch the progress of the driver configuration. There are 4-6 different drivers that have to be configured and a couple seem to take several minutes at the "installing drivers" process. I believe I was able to get this to work with even one of the drivers in a failed state, sorry I can't remember specifically which one it was. It was late last night and needed the phone for work this morning. I was just happy to get it going. :)
[T-Mobile LG G2x] Qballdz:
Not sure what finally happened, I guess just after patience and doing it over and over again it finally worked. Thanks for all of your help!!
[T-Mobile LG G2x] chrisdepew:
I too have never gotten the your hardware is ready to use notice. I am on about minute 6 right now and still haven't seen it. I am going to give it a few more.

Im sorry but not of this is working for me. Will lg even warrenty this? Is there a way to just return to stock form so I can wait for the ota
[T-Mobile LG G2x] chrisdepew:
Did you ever get a device is ready to use bubble? I have waited several times in excess of ten minutes and never see the device is ready to use. It just has a bubble that says new hardware found LGE usb modem or something like that. I have done this over, and over, and over again. It never works.

To the guy who asked if LG is warranting it, yes, I have a RMA number from LG to return it. As far as returning to stock, if you have flashed stock recovery then you are fine. In my opinion.
[T-Mobile LG G2x] chrisdepew:
Oh, you asking about waiting for the ota in stock form. That answer is no unless you can get this to load. Right now you phone is useless.
[T-Mobile LG G2x] PtbHien:
Doing these instructions will cause the phone to be running 2.2 Froyo right? I bricked my G2X when my usb cable accidently fell off my device when it was upgrading the firmware during the LG Update

[T-Mobile LG G2x] Jerster77:
Not working for me either

For some reason I cannot get this to work for me either. I have tried for two days to get this to work. I have downloaded everything several times my PC sees my phone and tells me it is ready to use. I have tried with debug mode on and off. It starts then stops in the same spot everytime. I have done several master resets. I have tried flashing other roms then going back to stock recovery. I guess it is time to send it in.:(
[T-Mobile LG G2x] crazythunder:
you haven't tried everything. did you try on a clean install of xp? did you try these drivers http://www.lg.com/us/support/mc-support/drivers/LG_T-Mobile_Android_USB_Driver_v2.2.zip? did you uninstall all drivers and start oiver? did you try a different cable and port? did you search through all my posts and look for something you might have missed?

CRAZY THUNDER

I just though that the pic was funny, untill i struggled to update my g2x then found the pic very rude to those struggling for hours to update and got nothing . and feel stupified by your pic.

I tried also the same following all instructions on a xp freshly installed.

didnt work i tried i 5 times. always failed at model dll msg not found 2010/ 3000

dloaded lg updater and worked first time..

Ive cm7'd and clwmodded 3 phones now..

there must be something causing it to work for some and not 4 others . I mean how do u screw up those very simple directions ?

maybe the program is just buggy.
[T-Mobile LG G2x] crazythunder:
so it's ok to make fun of others,as long as it doesn't happen to you? now that's just wrong lol.

anyways, it looks like you're close. many people have tried countless times,only to try once more and have success. it's noones fault other than lg's crappy software. you have to be creative when working with garbage like this. try uninstalling everything lg related. maybe do a search for older lg usb drivers. try different ports. try different cables. scream at your phone. nvflash cwm,wipe everything,reflash stock recovery,start over. everything i've read shows that people are having success with different methods. some got lucky and the update worked first time. some have been at it for hours,and then all of a sudden it worked. there's clearly no definite answer for someone who has followed the steps and failed. lg would give you less of a response than this. and then put up a picture like i did on their screen lol. good luck. i have some different versions of usb drivers i can send you if you have exhausted every other option.
[T-Mobile LG G2x] greatrafa:
The picture wasn't helpful at all. and it was a bit degrading. it's truly frustrating to have someone imply that you haven't worked as hard as you can to get your phone back up and running. As you said LG did a crap-tastic job with this, and it's not our fault it sucks. However it would be nice not to get blindsided with a tasteless joke/accusation when you're already feeling down.

I've been at this for over a day now, and I'm ready to call it quits. maybe t-mobile will send me another phone.
[T-Mobile LG G2x] rancidm:
i loaded xp pro sp3 on a win 7 box just to try it and it didnt..

Like i said i afterr trying 5 times i gaveup and tried the lg updater and it worked..

gues i got lucky on the lg updater huh ?

maybe try it on a different machine ?
[T-Mobile LG G2x] crazythunder:
degrading? really? wow. bit sensitive? i'm done here. you people have no sense of humor. i help and help and help. but it get's a little frustrating at times. i guess i'm not allowed to blow off a little steam? you're not alone as far as being at it for days. but i bet my last dollar you haven't tried everything. or you're doing something wrong. or you have the dwp model that supposedly can't be flashed,which i'm not to sure about that one...haven't read too much about it.
[T-Mobile LG G2x] rancidm:
its ok we still luv u.
[T-Mobile LG G2x] chrisdepew:
Guys, I have tried everything. Trust me. The only thing I can't try is a fresh install of XP. Sorry, I don't have they kind of power. I have tried on three different machines. If you phone will not be recognized, your done. You might as well stop. For those of you that are getting through part of the update through the kdz tool, keep at it.

However, if you are like me and tried every driver ever issued for the g2x including the newest ones, your done. Call tmobile or LG and get a replacement. I got tmo to send me one. I am tired of spending this much time with my phone, I have a family.

Somehow in the process, the phone drop what it needed to connect with a pc. I don't know what happened, maybe lg engineers can figure it out so it doesn't happen again. You can install every driver in the book and it will not connect. The phone is actually crashing the tool. That is what I have come to think. The drivers are trying their best to connect the phone but the phone is sending some back junk back to the driver.

I am not a programer but I do have some computer experience on me and that is just what I think. My phone should be here by Friday, I hope. I go on travel after that.

Someone Plz Help!

I'm running Vista and I've tried just about everything I see here from KDZ to everything else and nothing seem to work, does anyone knows what to do?
[T-Mobile LG G2x] Spunix:
It will not work on Vista or Windows 7, you need Windows XP in order to run it, I ran it on SP2 and followed my steps, it worked fine.
[T-Mobile LG G2x] gaww:
For some reason, normal USB connectivity go away when on the S/W Upgrader screen after awhile. I totally lost it a few days ago after trying on three computers (including an W-XP). When that happens, following the instructions for recovering is totally useless - period!

I am still able to connect with APX drivers and run NVflash. Paul over over on modeco.com set up a ROM for the 990 to perform a disaster recovery with NVflash. I have asked if he would set up a similar one for the 999.

I am surprised that no one at XDA with the necessary knowledge has done it yet here - especially given all the bricked devices due to the crappy LG Updater.
[T-Mobile LG G2x] symple:
this method drove me crazy!!!

A friend of mine semi-bricked his Gx2 yesterday running the update on tethering. I spent my whole afternoon doing this method until I gave up 5hrs later. . . :(

The Good thing is he called TMO CS and explained what happened and they're sending him a replacement.. (I basically NVFlash back to stock and called it a night)
[T-Mobile LG G2x] chrisdepew:
That's what I keep saying. The phone no longer has the ability to communicate with the computer. So, the computer has the drivers but it is not getting anything back from the phone.

I have a new one coming, so I am okay. Only bad thing, I have to use a BB pearl until it gets here.......;)
[T-Mobile LG G2x] gaww:
Lol - on BB pearl also.

I dont get this... i must be missing something or not... but come on guys help a person the right way and dont expect everyone to have the know at all you guys do... its fustrating to not have a phone... im currently unemployed and searching a for job like crazy i dont have a reliable phone to because my primary phone is bricked... I cant afford a new one and i cant afford to get a new one sent to me... so please stop with the read this post here and go over there... and just help everyone... in plain english please or a video or something... I cant express how many hours i spent in these forums trying to find a simple explaining... for those that it work you guess are not teling us the whole truth.. because for some reason you guys step away from your pc and then comeback and its fixed... do a video and run a camera nd if you step away it should be recored right.. but really take the iniative to help a person not ignor them or foward them away...

well i hope someone in here can have a feww mins to spare and do us the non techy some justice and do a step by step video... I cant express more but I really do need my phone to be up and running... its not fair LG screwed us over but we can make a difference if we help other in the correct way....

Thanks in advance...
[T-Mobile LG G2x] crazythunder:
dude, while i feel for your job situation, let me explain something to you. once the lgupdate is successfully run, it cannot be done again. it tells you that you have the latest software,even if you revert back to stock. i know. i've tried. so i can't just take my $1200 high def camcorder and record a documentary for you. if it was possible, i would. and what works for one might not work for you. i've been on here for days helping. i suggested a fix for someone earlier who was at it for two days and all of a sudden he got his phone updated. but there are too many variables with this crappy updater and with pc's in general. so that same fix may not work for you. click my name. search all my posts over the past two days, and you might find something you haven't tried yet. and that's wrong to accuse people of lying. and most of it is in plain english. most of us are not devs. we may use some of the terminology, but we usually try to explain as simple as possible. if you can't figure any of this out, it's time to sit and read for a few weeks. i used to stay up all night reading forums like this back in the mid 90's but it was about pc's. it's how i learned most everything i know. i never joined a site and on my very first post asked people to make a video for me. that's called spoonfeeding and i have enough trouble raising my 2 year old boy, let alone doing it for grown men. your post contained more rant than cry for help.
