Looking for working APX drivers for Optimus 4x HD - LG Optimus 4X HD

Where can i find the APX drivers for this phone since i can't flash anything in S/W update mode but i also can still use it as a APX device. I found a APX driver on the forum but that isn't for this phone.

You can't flash it through APX because we don't have the SBK.
Better buy another phone.

Okay thank you for the reply it's not my main phone i am just trying to fix it to use it as a secondary phone.

Try again?
If you still have the 'brick' in a drawer somewhere, the blob.bin along with all of the other files is now out to allow you to try restoring that phone. Somebody needs to be the first to actually turn it loose and see which firmware version it loads, etc. and it doesn't sound like you have any better remaining options.
Look in this thread: Maybe a working nvflash method

[STUPID] Managed to get into APX

Heey,
So today I really did something stupid hehe, I risked borking my tablet in the name of science.. I flashed a complete image from the Transformer, with kernel and stuff included. So yes, that kind of destroyed my tablet.
It won't load into fastboot at all, nor will it load up stock recovery.. But... I managed to get my PC to load it as an APX device along with the proper drivers too. Now I wonder, isn't APX the full acces bootloader for Tegra devices?
In any case, I will see if I can get my device back up and running using this APX stuff, I have high hopes it would work but am no expert on this.
If you have suggestions in the meantime, feel free to post them.
(Don't even get the Galaxy Tab boot image with the open lock by the way, only backlight goes on and stays blank all the time)
im sorry! help please!
i have the same problem with my 10.1v
Wouldn't hurt to give this a try

Didn't work for me, APX seem to work, but to be able to write files in APX mode you need to have the SBK. Which we don't have ofcourse, so it's back to the shop today, I know some people there and I'm just gonna play stupid. They will fall for it, will just tell them that after the battery was empty it wouldn't boot anymore. They can't even see the padlock since the only thing the thing does when you power it on is turning on the backlight
ONCE IN APX MODE, GO INTO CMD WINDOW (START>RUN>TYPE CMD), DIRECT TO THE DIRECTORY IN C:/NVFLASH, THAN FOLLOW THESE INSTRUCTIONS TO RETURN BACK TO NORM, nvflash folder included in the post,

Going around in circles please help

Okay so i did something i shouldn't of.
After buying a T-mobile dell streak 7 online, i found out it had been rooted with clockwork recovery mod by dj steve v4.0.1.4. When i tried working with it i found out i couldn't use the phone functions of the tablet so i decided to do a factory reset in the settings. To my dismay the problem only got worse and now when the tablet boots up normally it asks me for a password that wasn't on there before. I read on a thread somewhere that this is because the device is trying to decrypt something but that it's because there's no OS on it. I can still boot up in recovery mode and perform all the options in there.
So i bought a usb cable for it hoping that i would be able to flash it back to factory settings, but now i am unable to get it to work with usb.
I have a win 7 64 bit and i have tried downloading divers from all kinds of places which seem to be the right ones but windows will not allow me to install them and insists that the best ones are installed.
I've downloaded android sdk tools and installed all the components that are pertinent to this version and make (at least i think)
I've tried downloading PDAnet, the pc sync tool that is available on the dell site and that didn't work either. Under fastboot mode on the tablet the driver is installed correctly but still appears as a unknow device and i don't see the fastboot window show up when i plug it in so...
I've literally read hundreds of threads to see if maybe i could do it by placing update.zip files on the sd card and then installing them under CWM, some have worked, some haven't but when i reboot it's still the same.
Please help!!!

You need to grab a NVFLash pack, put device in APX mode, install the APX drivers, and install a complete full restore.

Thank you so much for taking your time to help.
Ok so i downloaded NVFlash, that i have found to be able to put my device in APX mode i need to hold down the power button and the volume - button at the same time when booting up but that sends me to fastboot. Is this the same as APX ? Sorry i don't know much about this.
Also when you say install the APX drivers, i have not been able to find these, could you send me a link ?
I don't mean to be rude or mean, but this is a question that has been answered a hundred times here, please look around and read a bit, we are getting tired of holding baby hands.
Thanks for your imput

Hey! Thank you for answering. Please don't be too quick to pass judgement, I have read hundreds of threads and i have downloaded all kinds of different drivers, roms, and recovery images. I've followed all the instructions of the related posts but the Tablet's OS wont boot up. I cannot install any .pkg updates because any option i select when i boot it up holding down power and volume + buttons sends me to CWM recovery mod and all the update.zip roms that i have installed this way have made no difference.
I have come to the conclusion that i need to flash a recovery image from the computer but i cannot because all the drivers i have found for it have not worked. My device does not appear as a drive therefore i can't see it in nvflash or even windows for that matter. yesterday i called dell support to see if they had any drivers available that weren't already posted on their site but with no luck.
The reason i'm writing this is because i was hoping someone had a similar problem and could help me, i know you deal with people that don't even take the trouble to look into the other threads every day, but believe me i have.
If you can help i would greatly appreciate it, or point me to what i'm doing wrong Tks.
In NVflash or APX mode the S7 doesn't appear as a drive. With your S7 on plugged into your PC, you don't see it as a drive? This should work right out of the box. Although some have reported the manual mentioned Driver. Zip folder is missing.
If hold the Volume + and - button in a plug into your PC, do your hear a beep? If so, you would then go into the device manager, select the APX device and install the drivars from the NVflash download package.

Check if you have the latest drivers, connect the phone in recovery (vol- and connect to PC), flash with LGFlash Tool.

There is no other way...
Did you follow the tutorial? Did you remained calm and gave time for windows recognise your device?
Did you uninstall and re-install the drivers? You're able to reboot in SW mode (vol- pressed while connecting to PC)?
Here you have all files needed:

Delete your old files, download new ones and follow the tutorial.
Remember to remain calm and give time to system recognise and install everything needed.

TNQ...I fix my LG...and know work perfect I put 20A kdz. 4.1.2. and phone work perfect
Same problem here
I have the same problem. I think the stupid thing I did was to install V20a without rooting the phone. Now I cant root it. IS11LG_SystemBackupTest.signed.ap would not run and when I try to recover either with LGflashboot or LG firmware recovery I get the same error message "morning call is empty" (very strange error message). I can go back to v20a but since I am not completely happy with it I would like to resolve it. Is there any chance to fix it? I am not very confident to format bootload or installing custom ROM.
Thanks

You cannot root the phone on V20a using IS11LG_SystemBackupTest.signed.apk, since that file is used for versions V10x. Check out this link for rooting V20a: http://forum.xda-developers.com/showthread.php?t=2180688

Uninstall all drivers and folders like "LG United Mobile Driver" and "LG USB Modem Driver".
Re-install the drivers:

http://www.4shared.com/file/ZSMf2x6n/LGUSBModemDriver_Eng_WHQL_Ver_.html
Take out the battery, press "Power Button" (just to discharge all phone components), put the battery back on the phone.
Press "Vol-" and connect to PC. Wait while windows detect the device and search in windows update for possible new drivers.
Windows won't find a thing but will take some time while trying...
After that you should be OK.
Just did similar to my phone and followed the advice in this thread - now sorted. Thanks guys you rock!
if u epic fail to manually force the drivers in just install android jdk open it and update it.

[Q] Optimus 4X HD full brick

I tried to put the CM10 on my phone, after installing the zip in recovery mode, I rebooted the device and it never returned to start. Does not show a single light. Do not enter in any way with any combination. When I connect by usb the only thing that appears in device manager is "apx device." Already tried so many things and nothing worked.
anyone have any idea what's going on?
by the way, I tried a lot here in xda before opening a thread.

No, no, no and no. the only sign of life when it is connected to the pc. Appears "apx" in device manager.
Yeah you are in apx mode, which is basically the boot section of the nvidia tegra chipset.
You should be able to boot normally by unplugging the phone, remove battery for a few seconds, reinsert and hold power button for about 10 seconds
Also try holding power and vol+ (hold them a while) you should be able to boot into normal recovery

I've try that but dont work.
In device manager the apx device is it properly installed or does it have the triangle?
When it first connected as apx device it probably asked you for drivers, i doubt you installed them.
I don't know if the apx drivers for the 04 are out already, check these terms in xda i know some people have been working on them.
Maybe you can find them here
If the device isn't bricked you are in a situation in which you should be able to flash stuff.
For some this method worked:
Try turn off phone
take battery out
hold vol- and put usb cable into phone
if s/w mode starts put battery in and flash kdz
Otherwise check this thread out
or this
I have to go out and can't follow you for a while, sorry

The only way for you to get connected in APX is without battery, connect to PC while pressing vol- & vol+.
Anyway... why you want to do that? APX mode doesn't work in JB.
Ok... I got it.
Did you tried to deactivate the APX device in device manager?
You can try to performe the bootloader unlock again (run adb and connect the phone while the program wait for device...)
http://www.4shared.com/rar/HFf4newq/LGO4X-UNLOCK-BOOTLOADER.html (instructions inside).
Or try to get in SW mode by trying untill it works... (connect to PC while pressed vol-).
Any update on the problem?

No, i think what happened was that all the firmware is erased and this naturally gave access to apx that should be hidden by the software. Probably there was some error when I wipe to put the CM10. I see no other explanation.
The phone is actually mine. Already sent it to warranty hoping they'll fix it.
Resuming, the phone went unexpectadly in APX mode and havent found a way of quitting that mode, couldn't boot S/W neither bootloader.
And btw the phone is carrier locked and to be honest I'm not sure if it might be part of the problem or not. Anyway in about two weeks the phone should be back and hopefully fixed. If not I'll check here for some more help guys, thanks for attetion so far

Id send the device back into lg, is it unlocked? defaulting to apx say to me you have a missing/ corrupt bootloader and without access to nvflash (thanks again LG...) and if is we cant fix it.
You probably got into apx mode by holding both volume buttons while rebooting.
If the phone isn't corrupt you should be able to get out of apx mode by connecting the usb to the phone while holding vol-
You better try several times, eventually you should be able to enter in sw mode.
I don't know if the method you posted will work because of the apx drivers, someone was working on them for the 04x but i think the thread wasn't updated in a while
