[Q] Q How to root software version E97011c

[Q] Q How to root software version E97011c - AT&T LG Optimus G

Please help. I am a convert from Blackberry, the LG Optimus is my first Android. I really want to root this phone, mainly to remove the bloatware and also install a few of the cool apps that can be run on a rooted phone. I have the newer AT&T software version E97011c, and it wont root. How to go back to the old software version so i can root this phone. And good bye Blackberry!!!!

You need to use a tool called LGNPST on your computer to install an old version of the firmware that can be rooted.
I have not done this and can not offer too much advice.
But, you need to:
1. go HERE.
2. Pick a nickname.
3. Set your channel to #lg-optimus-g
4. Fill out the capcha.
5. Ask for the link to LGNPST (it can't be posted on here)
You can ask people there, they know a lot.
Instructions from PhantomPhreak53: (I believe these may be outdated... there is a newer version out I believe, again, ask the people at irc)
1. Install LGUnitedMobileDriver_S4981MAN38AP22_ML_WHQL_Ver_3. 8.1 (LG USB Drivers)
2. Install LGNPSTv1.3_Lab_Verison_RightClickReg (LGNPST)
3. Install LGNPST_GenericModels_Ver_5_0_12_0 (LGNPST Generic Modules)
4. Install LGNPST_Components_Ver_5_0_20_0 (LGNPST Components)
5. Copy the Models folder to C:\LG Electronics\LGNPST\
6. Start a command prompt as admin
7. Type regsvr32 "C:\LG Electronics\LGNPST\Models\LGNPST_LS970.dll"
8. Download the proper .tot file for your phone
9. Rename .tot to .bin
10. Open LGNPST
11. Select the LGNPST_LS970.dll and your .bin file
12. Press Start
If LGNPST errors out at 85%, turn your phone off and hold the power button until the phone powers on, then release.

How to "root" your Optimus G
(Optional if you have another means of un-RARing) Download and install 7-zip from here. You need this to open certain types of archives (specifically .rar, but you might also want to open .tar, .bz2, or other types of archives in the future). This program is supremely awesome in its ability to open almost any archive you throw at it. It's also unobtrusive and efficient.
Download and install LG USB Drivers from here. Without these drivers, your computer won't be able to effectively communicate with your phone. This is vital for the steps we will be taking.
Enable USB debugging by going to Settings->(General)->Developer options" and checking the box next to "USB debugging." You will get warnings. You can probably ignore them. This setting will allow you to run commands on your phone from your computer (via USB). For more info on the Android Debug Bridge, click here.
Download and extract (using 7-zip (or whatever)) the root exploit from here.
Connect your phone to the computer with your USB cable.
Open RootOptimusG.bat and follow its prompts. Your phone will reboot twice, do not disconnect the USB cable until this has happened and the script says it was successful.
Go to the Play Store and install SuperSU (or click here. Run it and make sure it works. This program allows others to gain access to superuser privileges. For more info on rooting and what kind of stuff it lets you do, click here and/or use Google.
If that didn't work for you, try bigworm50's guide here.

Do yourself a HUGE favor and don't do the version that requires all of the steps that bleached posted. They'll work, but they are a HUGE PITA compared to downloading and installing: tSilenzio's Automated LGNPST.zip In addition, it's a newer version of LGNPST. I believe that it's available on the irc channel that bleached linked.

LGNPST is grayed out

Sorry for being a noob but I downloaded tSilenzio's automated LGNPST.zip and I can load the LGNPST_LS970.dll file. But LGNPST is grayed out for everything except the DLL section. I can't pick the bin file even though I already downloaded the tot file and converted to a bin file. The phone is plugged in PC software mode. Thanks for any help.

I think its volume up, volume down, and power. Or if that doesn't work turn it off and hold up and down, then plug in the usb.

Well, I did say I thought there was a new version. I have not had to use LGNPST yet, so luckily I'm pretty in the dark about it.
Thanks for pointing it out though.
:good:

Thank you. 1 more thing, when Jelly Bean comes out for this will I be able to upgrade over the air (If I only remove bloatware and install a few apps that work on rooted phones?) ]

I bought a LG MyTouch 4G Slide (myTouch Q)
I rooted it, upgraded the software, everything was great.
I was flashing a theme through zip and suddenly, it cut off and now my phone is unresponsive.
The LG splash screen shows twice, followed by displaying the following message:
E:Can't find misc
E:Can't find misc
Finding Update Packages..
E:unknown volume for path [SDCAR
D:/download/(name of the zip file)]
E:Can't mount SDCARD:/(File location)
Installation Aborted.
Factory Reset Failed
Restart Factory Reset
Then the cycle repeats its self.
I cannot access bootloader (power+volume down) no matter how many times I try, it continues to do the same process.
I have searched everywhere and cannot find the answer to this problem, does anyone know how I can make my phone work again?

how'd you upgrade the software? try loading a stock rom either through your computer or sd card, I'm not familiar with the exact process for a slide, but that's what I'd try.

I did it the old-fashioned way. Went into settings and searched for updates, then T-Mobile updated me OTA.
The phone worked perfect prior to the theme.
Every file I've put on the sdcard seems to not have any effect on this problem.
Do you know where I can find a stock ROM for LG M4GS? All the one's I've seen around are for HTC.
I downloaded ODIN but it only tells me to connect the phone when it's plugged in via USB.

I'll donate to whoever helps me, really need to fix this issue.

how'd you try to flash the theme? through a custom recovery?
and why did it stop?
did you give hard factory reset a try? (dunno what exactly it resets but it might help, and it might actually be exactly what your phone is trying to do according to the screen output):
http://forum.xda-developers.com/showpost.php?p=20310765&postcount=8
if that does not work, try to at least get some more logcat:
install the android sdk, plug your powered-off-phone into usb, run:
adb logcat
it should start the service and be:
Code:
- waiting for device -
then power the phone and post the output...
good luck

Questions should be asked in Q&A forums, not Development forums.

Attached is a screenshot of the error I receive everytime.
The phone does not stay powered off when USB connected, keeps trying to boot.
After two splash screens, the error screen shows.
I used SDK to obtain the screenshot, but none of the other tools seem to work.
Below I have attached the screenshot.

so did you try the hard reset?
if you did, can you get into recovery mode (supposed to be A [QWERTY] + F [QWERTY] + Vol Down + Pwr) or s/w upgrade mode? (E [QWERTY] + Vol Up + Pwr)
if you can get into either one you're probably ok.
through recovery you can flash whatever, and through s/w upgrade you can use a tool called LG Mobile Update Tool (you wrote about odin, which is a samsung tool for samsung phones. this is apparently the lg equivalent):
download the original 2.3.6 firmware here:
http://forum.xda-developers.com/showthread.php?t=1825818
and do what they say here (its for the mytouch 4g but i guess the process is the same. you might wanna read up on this a bitbefore you do it):

I looked every where for this and hope it does not violate any rules - but wanted to repost so that it might help someone else. Again if it is a violation then I apologize but was just before returning to LG for repair.
If you have a tmobile prepaid LG c800 ( may work with contract phone not Sure) this should un brick your phone. I am not the author and take no credit it came from here :
http://androidforums.com/mytouch-q-...-progress-porting-custom-recovery-over-2.html
1: Download and install Drivers from LG site Mines is C800VL. http://www.lg.com/us/products/documents/LG_OSP2.0_Setup_2.0.07.20111130.exe
2: Download and install LGMobile Support Tool leave open i read it is needed to flash. http://csmg.lgmobile.com:9002/client/app/B2CAppSetup.exe
3: Download the .kdz file Its for C800DG but works for C800VL , C800VL don't have a kdz file at least i don't know i looked every where. V10D_00(C800DG).kdz - 4shared.com - online file sharing and storage - download
4: Open LGMobile Support Tool leave open.
5: Download the Flasher from post one
http://androidforums.com/attachment...s-porting-custom-recovery-over-updater-2-.zip unzip and install msxml.msi included with zip
open KDZ_FW_UPD.exe set to 3GQCT - Smart Phone(WM)
browse for KDZ file (V10D_00(C800DG).kdz)
click lunch software update and you should be in S/W Upgrade mode wait for program to finish if it errors leave phone in update mode and click lunch software update again.
One note make sure to download the correct version, there seems to be several the "LGMobile Support Tool"( file name "B2CAppSetup.exe") one will take you to the LG site and do an automatic update and tell you that your phone is not supported and to contact LG and the - "KDZ_FW_UPD.exe" it will be the one with the "browse for file" on the opening screen, also not sure but on another web site it said to use windows enabler file V 1.1 it will run on the task bar at the bottom as an Icon of the seperate windows tiled, click on this so that it says"on" not postive it is necessary but this how I ran the KDZ file. There is a V10V kdz file but it would not work on mine.
Update: after flashing with kdz - V10D_00 (2.3.4) Reflashed/updated with kdz V10v (2.3.6) would not upgrade OTA or at the lg site.

[Q] p769 - softbricked by noob

i finally figured out how to get CWM installed and working, after a couple of months of fighting with it, off and on. so, i guessed that meant i have my bootloader unlocked - "wrong!".
i deleted some thing that wasn't supposed to be deleted, then the damned cell network and lan network stopped working (keeps saying com.android.phone has stopped). so i was going to put cyanogenmod on it, because i thought that i could, and just be done with the whole "missing apps" crap. it turns out "just because you CAN put CM on it doesn't mean you CAN put CM on it". i bricked it. i have NO options to "load" or "flash" or "boot" any thing when the phone is booting up. i would love some clarification as to what i CAN do from here.
i would rather install CM and be done with all of this, but i'll take any advice that gets rid of the problem. the biggest problem is understanding how to put CM on your phone, or to do any thing at all like that, when you cant get into any kind of recovery / boot menu, even though you ARE rooted... i don't care if i have to install cyanogenmod or some one else's CWM backup, i just don't know HOW to do it - especially with no windows (only linux). it's a rooted p769v20d (originally p769v10g).
thanks

i was going to try some stuff mentioned in other threads, but i don't have access to a windows computer - and i don't think i need to root my phone again any way, considering it is still rooted.

fwiw, regarding the mysterious deleted app:
i lose my internet signal as soon as it says "com.android.phone has stopped", then i get it back again right before it says that message again - it ALSO shows a cell-phone signal right before that message. this repeats over and over and over every few seconds - aggravating as hell...
here's the apps that i still have installed: http://forum.xda-developers.com/showthread.php?p=45774770

Nice thread title. That is how I am feeling right now with this phone. I feel like calling tech care and yell at them for a bit to vent. Anyway, why not install fastboot for Linux and flash the ics u and x? I uploaded my u and x folder in the Unlock Bootloader for Noobs thread. Then, flash the 20h.....oh, dang.... sorry. Forgot.... no Windows. Maybe do the built-in restore by holding the volume down, home and power keys?

thanks, but i think i finally got it working. i never knew, after all this time, that after you do the l9recoveryinstaller, at the reboot, there are no cues to tell when when to hit some buttons, and it's not clear what buttons to hit. here's what i did, and, so far, its progress:
1: be rooted
2: install busy box, completely
3: install l9recoveryinstaller
4: reboot
5: after you see the LG logo, hold vol-down until you see the flashing lights (i thought you see the flashing lights and THEN you hit vol-down, but i was wrong).
still fighting to get a rooted rom installed ...
if i choose "install zip from external sdcard" is says:
"finding update ... opening update ... installing update ...installation aborted".
if i choose "restore" instead of "install" it will not let me select any thing, it just keeps saying file not found, when i try to select any further options, whether "restore" or "restore from external sdcard" or "advanced restore from external sdcard". and i already checked to make sure the sdcard was mounted...

I think your phone bootloader is locked, you cannot flash any custom rom zip file. It will soft brick your phone.
Please restore P769 CWM back from this thread http://forum.xda-developers.com/showthread.php?t=2136204. Download backup file and unbzip it. Put extract files in your sdcard /clockworkmod/backup/2013-08-30.12.00.00 folder. Extract file should contain several .img, .tar, .a, .log and .md5

Well correct me if I am wrong, but I guess you "only" deleted some system files, right? Do you remember which ones were the ones? Or at least the folder they were in? Then you only need to extract that stuff from a kdz/ the bin file and push them on your phone using adb or maybe even the dd command.
Maybe if someone is kind enough, he ll probably provide you with the files you need. And cmiiw, but I guess you deleted stuff from /system/app...

Lol, you are a Linux user, you should know how to get your hands on a windows.iso
However, i would recommend using a portable windows xp (bootable usb)
VR is not the best option IMO
You will need this program http://unetbootin.sourceforge.net/

Sorry I can't provide a link to the iso but do a google search for

It's depend on what method you use. You can flash kdz using offline method here http://forum.xda-developers.com/showthread.php?t=2085344
or use LG mobile support tools from LG website. If you choose this you don't need to download any kdz. It'll download kdz automatically from LG server then flash it on your phone. It take about an hour or two.

thats awesome - i wonder if i can get by with using that on wine on linux, instead of borrowing a windows computer... i'm gonna try it...

well, the verdict is in, on this one: i'm screwed. i've tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried and tried, and i can NOT flash this damned phone. it's BRICKED.
i borrowed / hijacked my brother's computer (windows7), all day. i tried a few different things - i even tried the same way i flashed it to update it ( http://forum.xda-developers.com/showthread.php?t=2356536 ), which was worthless to unbrick it.
the problem in every case was that every time the damned flasher got so far along it would "lose the connection to the phone". drivers installed, etc, etc, no difference. i suspect its because i couldnt connect it in all the various modes (mtp ptp etc), since the ONLY way it would connect is in "software upgrade mode".
i had to buy another phone, won't have it till tuesday. lesson learned: NEVER buy a phone that didn't come from samsung... you just can't do what you want with them, without a lot of time, patience, experience, and a windows computer.
thanks for all the help.

Did you try to recover your phone with LG mobile support tool. It can reinstall rom in almost any soft-brick case. Please try it if you haven't try it yet. Many people restore their phone by that software. The steps are
- Download LG mobile support tool from LG web site
- Boot you phone to S/W update mode
- Run Tool and select recover phone
- Wait about 1-2 hours to download and flash
If it's not hardware problem, this should solve your problem

i never found that on their website, and i looked quite a few times. however, i noticed when i used the b2clientsetup.exe that if i run it without running the shttp server first, that it downloads a support tool from the net, which does not work - keeps saying phone lost connection. not sure if its the same tool.

Yes that tool. In my region, it has download link but for P769 it has request repair service.
Download from http://tool.xcdn.gdms.lge.com/client/app/B2CAppSetup.exe
You must remove following lines from hosts file

yeah, that's exactly what i did, but it would keep "losing the connection to the phone". not sure why, but i suspect it was a driver issue - and i installed the latest drivers, which made no difference. i also went back and installed older drivers, which made no difference. i must just be lucky as hell, or some thing .

In my country (RO) there are some GSM Repair Centers. You should not give up and you should go to them. Par example, I flashed an HTC Mozart when the battery was dead and I bricked it (idiot, I know). I went to a shop like the ones mentioned above and I think he said that he has to flash the phone using a JTAG or something like that (I know that he has to open the phone to reach it's motherboard, solder some **** out there and... flash I guess). The whole thing was about ~20E. Anyway, keep digging, maybe you'll eventually find something that works for you. If not, go to someone who can "force flash" it and maybe you can save the device.

[Fix] [How to] [Unbrick] 'fastboot mode started udc_start() (LG-P500)

REMEMBER: DO THIS AT YOUR OWN RISK..DO FOLLOW STEPS SO THAT YOU WONT ENCOUNTER ANY PROBLEMS.!
Thinking that your phone is bricked??
Ever wonder how to get the hell out of the ''Fastboot mode started udc_start()''..??
Worry not.. The help is here.. )
Note: *This usually happens when you flash something and failed.
*Don't worry your device is not fully bricked.. There are many ways to fix this..
*Before proceeding please make sure your phone is charged even if the backlight is always on while charging..
* Remember make sure LG UNITED (Driver of your phone) is already installed (to avoid PHONE WAS NOT FOUND)!!!!!!
*This will restore your Original Rom.
*This Works On All Variants Of Optimus One (LG-P500,LG-P505,LG-P506,LG-P509) and other few devices
*For the Prerequisites (Below)..
Prerequisites:
*KDZ Updater/Lg United
*Windows Pc/Usb cable
INSTRUCTIONS:
STEP 1:Download the prerequisites. Disable all LGE modems under modems from Windows device manager in
the control panel.. (Simply click start then type ''Device manager'' click it. then you will see there under MODEMS)
STEP 2:Exract the files..Open the KDZ Folder to your desktop and Right click on the "KDZ_FW_UPD.exe" and
click RUN AS ADMINISTRATOR.
STEP 3:Open the "Original firmware" folder and run it, type the serial number on the blank form entry. You can
Find you serial number on the back of you phone, remove the battery and look for the sticker attached to you phone.
If you fail to launch this software, you will have to install net. framework 4.0, just open your browser and type
NET.framework 4.0. Download it and install. After this you are able to run the software.After you type down the serial
number of your device click save and just save it on you DESKTOP. Wait until it is finished. This takes some time.
Internet connection needed as this software is downloading the ''KDZ file'' needed for the "KDZ_FW_UPD.exe".
STEP 4: Now lets go to your phone,press and hold both the back(return) button and the volume up button and
simultaneously connect the USB cable.. (The phone should light up and say Emergency mode!! in a green
The phone should light up and say Emergency mode!! in a GREEN/YELLOW background. (if not don't continue...)
STEP 5:After the download lets go back to "KDZ_FW_UPD.exe" .. Follow this settings... TYPE:3GQCT
PHONE MODE: DIAG Select the cab file (the one you downloaded ''KDZ file'' located at DESKTOP) The version
will depend on the ''KDZ file'' you downloaded. EX: (mine is V10F_00.kdz so the version will be V10F_00) after this
click "LAUNCH SOFTWARE UPDATE'' THIS WILL TAKE SOME TIME..... WAIT FOR IT....
For most of you it would probably say PHONE WAS NOT FOUND!..To avoid this please make sure you have
follow my note written above..
STEP 6:DONE... ITS ALL FIX NOW.. YOUR PHONE WILL REBOOT NORMALLY WITHOUT THE
'FASTBOOT MODE STARTED UDC_START()' :good: :highfive:
STEP 7:AND FINALLY.... ONE MORE STEP.... PRESS THE "THANK" BUTTON IF I HELPED YOU .:fingers-crossed:

First, this method should work for all Optimus One variants. P500, P505, P506, P509, and a few others
Second, a couple corrections, if you don't mind...
Step 3: ... type down the serial number... This is incorrect. This should be IMEI number. IMEI and Serial are two different things.
Step 4: ... Emergency mode!! in a green background... Emergency mode has a Yellow background and "Emergency Mode" printed on the screen in Red.
Third,
When something goes wrong, the device will first attempt to boot to recovery. If it can't boot to recovery for whatever reason, then the device will reboot to fastboot mode. From here there are other options, not just KDZ. KDZ should be the last line of defense as it has bricked many Optimus One's and it's variants. If the device drivers had been previously installed correctly to a Windows PC, then fastboot.exe or any GUI tool for fastboot.exe can flash a recovery that can then be used to repair/replace the device's OS. Linux/Unix users don't need drivers to communicate with USB devices, only a 51-android.rules file and a fastboot executable for Linux/Unix.
Don't take what I've said the wrong way. I'm not trying to shoot your guide down. This is the kind of activity that is encouraged at XDA not discouraged I just wanted to inform you that there are other options.

Thanks a lot. You really saved my phone. Worked like a charm. My device is back to life and working good
But some apps (play store, maps, etc) are shown as broken as I had earlier moved them to a second partition on my SD card.
I tried downloading play store apk, maps apk and tried to install, but installation is a failure
Is there any way to restore these apps?

Serial number
Hi there, I'm a complete novice at this but giving it a go...I'm up to step three and have opened the original firmware folder and run the application, but whenever I type the serial number (or the IMEI number - have tried both) and hit "save" it says "Unsuccessful in connecting to server or phone information is wrong!"
Any tips to get through this step?
Thanks

I also have a problem like this, and at the same bootloop "fastboot mode started udc_start ()". So I followed the tutorial as you post. It's just that there is a problem at the last moment, that is the error message by KDZ (like in the picture), whereas in the log is written "FINISHED" but instead restart my phone to fastboot mode (after previously being in emergency mode) and nothing happened.
Earlier after I remove the error message, there is a new log message after the "FINISHED". Is there someone who can give me help? :angel::angel::angellease !!! Until now my LG still brick do not know how what I can do.......:crying::crying::crying::crying:

.532 is the onlt firmware that has a root exploit, use the one that is linked in my downgrade thread, will work on all versions of the ZU locked and unlocked
Root with binaries tool - use option 0 or use [NUT]'s tool (see
my downgrade thread again)
That's it for now, will have a close read soon...

Thanks - @blueether -
Updated thread.

You can probably remove the section about the camera as that was a Z1 issue, not affecting the ZU

I am glad to at least see you guys trying to put everything into one thread.
This is still a huge amount of instructions for a newbie and any reduction would be great but at least having what you currently have put into one thread is still a major improvement.
Good going guys and thank you very much!

Great! We got one process shortened.
I am neither a programmer nor a hacker but I will try to contribute what I can for a "Rooting Xperia For Dummies" guide.
The next suggestion is actually lengthier but may make a scared newbie feel more safe since it comes from the Google Play Store.
Instead of dialing code into the phone,

why not change that to download an app from the "safety" of the Google Play Store?
https://play.google.com/store/apps/details?id=com.neoscreenager.xperiaservicemenu
It appears to be a good app that works better than always dialing code for someone who plans to access the service menu regularly anyway.

Great guide!

Brilliant guide :good:, thanks for the hard work.

I wasn't criticizing anyone in the post that you quoted. I was just explaining what I believe needs to be done.
I have posted in more than one thread that I don't have any tech skills to make contributions in that regard. The goal of simplifying and streamlining the root process for the public is going to take someone with developer skills that I simply do not have. I don't know the first thing about Linux and know nothing about writing Windows batch files. How much more humility regarding my tech skills do you want?
I get it. You guys are content with just doing rooting for yourselves and could care less about how OEMs mistreat their own customers let alone give empowerment back to the public or even stymie development to a degree that rivals Microsoft for that matter. If anything, I have seen more sympathy towards OEMs and patronization towards the public posted on this site.
I won't bother you guys any longer nor will I attempt rooting my phone with instructions on how to root and unroot all over the place in many threads with the lack of support being what it is on this site.
Have fun continuing to live in your own world indifferent to the rest of it. No wonder the rest of the world doesn't like nerds. At least I figured that one out after all these years so it wasn't a complete waste of time coming here.

meh
Lordmanhattan and I, and a couple of others that dont post so much now have put hundreds of hours in to help others, bring all the info into a couple of threads.
If someone has a problem with the process and has not just "how do I root my ZU" we (the general users of this section) will go out of our way to help.
I feel that having all the info in one post if counter productive, it becomes too much to read, too easy to lose you way - foss mantra: small tools to do small jobs => small guides to do small steps
The process is not that difficult, but there are many permutations of what the user is starting with and what they want to end up with.
Again: If they ask an intelligent question in the guide threads they will get a concise answer, if they open a new thread with the same question that has been answered 100 times before they will get a shot answer that they may not like.
The process is not overly broken, people just need to be less self entitled, not everything in life is as simple as they are

Could not enter Recovery after flashing 757 kernel
Thanks for your helpful post.
I just have a problem at step 25 (Go to Recovery) under ROOT 14.3.A.0.757. Everything was fine until I attempted to enter Recovery mode to install SuperSU. After flashing the 757.img kernel, I disconnected the cable, pressed power button, and hold volume down (I also tried volume up) button when the Sony logo appeared on the screen. But my phone just kept booting to Home Screen.
I was wondering if anyone had had the same problem? If so, please help me to fix this.
Thank you in advance.
Update: I managed to enter Recovery mode by pressing both volume up and volume down after pressing the power button. Everything is fine now. Thanks again for a very clear and complete step-by-step guide for a Noob like me.

You're not supposed to hold the volume button up/down, but you should simply press it once or twice when the LED lights up above the screen

Hi, I am trying to flash my phone following the steps for Flash 14.1.B.1.532 ftf file to phone. Once I get to step 13 I have a problem. I am using Flashtool to flash the ftf file in flash mode but there are no files to select from. I have already placed the ftf file in the firmware folder.
PS:the flashtool is version v0.9.16.1. Has anyone experienced this problem?

Hi blueether. Thank you for your link. I would like to ask you a question. My ZU firmware version is .290. Should I update to 757 then downgrade to 532, root and back-up the TA partition. Or should I just upgrade from .290 to 532, root and back-up the TA partition. Which do you think is the best way? Thank you.

for a start 532 (4.2) is older than 290 (4.3)
@ OP This is the porblem with yet another guide thread about rooting the ZU...
As of 4 or 5 days ago you dont have to down grade at all. With the thread I linked to you can root any of the current Sony firmware I think (untested, but 767 will root).
I would:
upgrade to the latest 4.4.2, Sony's x.x.x.767 FTF
root with the tools linked to in that thread
back up TA
unlock BL if wanted/needed

Soft-Bricked LG GT540 Optimus

Hello. I've tried using multiple ROMs in my rooted phone with KDZ Updater, and I guess that one of the updates hanged, or maybe it was something else... I really don't know. What I do know is that my phone currently isn't able to enter recovery mode, and is also not showing any boot logos (neither 'LG' nor 'Android').
I did see some threads about this, one of them talking about starting in Download Mode and using KDZ in CS_Emergency mode with some French ROM. Well, I tried that and as soon as I press "Launch software upgrade" the program freezes until I plug my phone off the PC.
I feel as if something was stuck in my throat and the only way to get it out is by completing this... so any help will be greatly appreciated!
PS: All this happened in the process of trying to install Cyanogen Mod 10.1 (which I did not try yet).

Need to make sure to get the right firmware, DLL file, and make sure you have the right port set on the program.

Thanks for the reply!
I appreciate the info, and I'll be checking what you've said. All the links in that thread are inaccessible because Fileserve only lets you download what you upload. Anyway, I'm curious as to what this "DLL" file does on a smartphone... why do I need these things? I never heard of them being mentioned anywhere.
I'll start educating myself ASAP. Meanwhile, thank you very much (and by the way, if it's of help to anyone, my phone is a GT540g from Personal, Argentina.

You're welcome. Sorry, didn't check to see if the files were still there and most every other site just had reposts of the fileserve links. However, finally found what you need here:
http://files-gsm.ru/lg flesh/GT540gAT-00-V20a-722-34-DEC-28-2010+0.dz.zip
I found this dll for your phone but not sure if it works with the firmware you have for that version:
http://www.mediafire.com/download/9v9e78xronadm0c/GT540g_100506_MP.dll
"A dynamic-link library (DLL) file is an executable file that allows programs to share code and other resources necessary to perform particular tasks..."
Basically it ties together a few things in Windows to let the flash tool work for your specific device is my understanding. But they have to be specific to the phone or it won't run once it checks the build.prop of the phone vs the firmware you're trying to install.
Keep in mind, I do not have this phone and have no way to test if they will or won't work so just like any other mod or upgrade - you do so at your own risk.

Thanks, but...
First of all, I'm very sorry not to have replied before, but I've been busy. Anyway!
Thanks, I appreciate the links, but I don't understand where to put the .dll file in my phone. I know you'd think I'm an idiot who doesn't know how to use Google, but I actually did search beforehand. I simply don't get where to put it.
Also, if it's worth the shot, I just noticed that I should disable the "Modem" that activates when I plug my phone in. The problem is, KDZ just does this simple log [attached] and states "===FINISHED===" (Note that I have 2 Modems listed in my device manager [attached screenshot])

Solution GT540
Thanks for your help everyone, I came to a solution after a full year lol. Here's my enlightenment, from another Thread:
Just wanted to leave my 2 cents here, I've been trying to do my best since around august 2014, no success. 2 days ago I retried this, and I DID IT! I will tell everyone what I did very shortly:
My problem that I solved: I can boot, device works like a charm. But: no boot logos, no recovery.
My solution for TL;DR: UNINSTALL ALL DRIVERS FROM DEVICE MANAGER 1ST, then reinstall. After that, flash a fastboot ROM and use it to WIPE ALL THE DATA IN YOUR PHONE! THIS was what I needed and was never explained: you had to WIPE the old data in order to get the boot screens back.
IN THIS ORDER (THANK YOU to those people from previous replies, gathering all your info was of great value):
Uninstall all of your phone drivers from your PC!!! This is what made most of my headaches go away, just use Device Manager and uninstall anything from LGE. After that, plug in your device in your USB ports (always BACK ports, not front ports, important). It should detect all drivers and download them.
IF it fails (it generally does with LGE USB Modem), you can go to Device Manager > Unknown Device (the one that wasn't recognized) > Right Click and Update > Choose 2nd option, then choose "choose from a list of local controllers" (or whatever the button says). After that, scroll down to LG Electronics, Inc. and install what didn't install.
I also found these drivers, but I did not test them: http://www.mediafire.com/download/p693hcz6kkouh19/USB_Driver_LG_GT540.zip
Huzzah!
Now you're set to begin:
FIRST thing you wanna do is a factory reset, this is something I'd forgotten with time, don't make the same mistake as I did. You can do it by turning your phone on and pressing Volume +/- & Home & Quick Search buttons all together for 5 seconds (it works, be patient and wait for it, even if you open the camera or any other stuff).
Download this Google SDK Tools (unzip and put the folder in C:\ drive) and this Fastboot drivers for GT540 (unzip and put the files inside the folder in C:\android-sdk).
Skip this next line if you know your ROM has fastboot.
Now, if you don't have a ROM with fastboot, I recommend you use either European Open+Fastboot or V20C Orange France Fastboot ROM.

Since you have Fastboot enabled, now all you need to do is turn off your device (all this with its battery on it, no weird things) and hold the Camera button before turning it back on. This should take you either to a black screen, or simply to no display, like me. Either one will work anyways.
Now press the Windows key > Type cmd and open it with Right Click > Run as Administrator.
In it, type all this, command by command (you can paste by right clicking):
cd C:\android-sdk
fastboot -w
fastboot erase boot
fastboot erase system
fastboot -w
fastboot reboot
Click to expand...
Click to collapse
And now it's go time! Do what everyone else says in here: Take out your phone's battery, SD and SIM cards, fire KDZ Updater up as Administrator (If your KDZ freezes, then it's either faulty or you did not install msxml, look for a good KDZ that comes with that file and delete your current one), choose CS_Emergency PhoneMode and:
1-Plug your phone while holding the volume DOWN button (don't worry! My phone didn't show "Download Mode" either, if you hear the Windows "Somethingpluggedin" Bump noise, it's ok).
2-Flash French V20A
3-Unplug your phone once KDZ says "==FINISHED==".
4-Plug it once again, holding the volume DOWN button.
5-Flash out.kdz (remember! it's CS_Emergency).
