Just installed the v20 and done the boot unlock. Now my phone is stuck in a security boot loop error, I cant get into recovery or into software update mode. Is this screwed? Cant even get back to adb or fastboot!
Can you get into APX mode? (Vol+ Vol- Power)
I've seen an SBK posted somewhere in forums, it can be used to reflash using wheelie and nvflash

To flash in LGFlash, you need com port, to get com port you need to get into software update mode.
APX is like "direct flash access" mode.
didnt work for me
Looks like the root went fine for me, the unlock somehow screwed up though, because ive now cat'ed the imgs over and am getting the DRM secure boot failure. Cant get into recovery, bootloaders bust and software update doesnt boot either. Can only get into APX, hopefully I can do something with that.

If you hold vol- power you get what?
Edit: I mean, take out battery, hold vol-, insert usb, repeat if screen gets striped.
There may be 3 possibilities:
When you did cat the file was not found -> you screwed corresponding block.
You misplaced blocks: overwritten boot with recovery and recovery with boot.
You did not check unlock state: in hidden menu or s/w update.
I'll go with the last option on that. I think my bootloader is still locked and the copies went fine.

I think you should keep trying, because the thing you described is because of insufficient voltage at start moment.
Try to connect to more powered usb port / disconnect other devices from same hub (!!!), as soon as you get into S/W update mode reinsert battery.
or try not to use usb3.0. i coulnd't go into s/w mode because my hub was connected to usb3.0 so when i connected phone directly to my usb2.0 s/w screen showed
AWESOME
Thanks man. I used a different USB port and the same was happening, though I thought what if i put my battery in as soon as it starts. Viola! SW Upgrade is working!
Just have to get the battery in very fast.

Ok so i was on 2.2 Firefly and tried to flash stock GB. Did a reset and wiped the dalvik. Put the phone in DL and Windows (Vista 32b) is not detecting the phone, it spits a usb unknown device. Had to pull and plug the usb a few times until it finally get a good detection in Odin.
Now the real fun begins.. Started the flash and got stuck at "Do not turn of target" for more then 5 minutes. No activity, no bars going up.. nothing. I unplug the usb and replug..No more detection. Remove the batt and try DL again...Bingo black screen of death ! and can't go in DL anymore.
I got a usb jib and it works.. hooray or so i thought. Plug in the device and now windows is still not detecting the phone and install a "unknown device" under usb section. I uninstalled all the drivers i had and reinstalled... same issue.
Downloaded heimdall and that's were the revelation came... My device is f*** up real bad. My USB\VID and PID are now both 0000 (VID_0000&PID_0000) and not "VID_04E8&PID_681C". Windows driver can't recognize the device because of it. Tried putting a entry with 0000 in the driver .inf but it still can't detect the phone. I only have a "Samsung USB Composite device" with a error code 10 (cannot start device) under device manager.
SO..Is there a magic solution to bring this thing alive with Odin or heimdall or is jtag recovery the only solution left ?
EDIT: FINALLY !!!!!!!!!!!! After 3 days of driver install and port switching i found a way to get Odin to detect my soft brick phone in DL. I used my usb hub (yes you read that correctly) to plug in my phone and Odin detected a com8 connection. I flashed via the usb hub and i'm now back on track !!!
Stuck with this same problem...
I can get it into Download Mode ONLY with a jig...
other than that anything i do (turning it on, plugging it in) makes a weird screen appear that has the following:
[cell phone] .. [caution symbol] .. [computer]
both windows and ODIN will not detect phone both on this screen and in download mode
got ODIN to detect phone twice after multiple attempts and it says that it starts the flash but that is as far as it gets... second time i left it all night connected with ODIN running in a feeble attempt to get to flash back to stock
trying different USB ports, i do not currently own a USB hub like the author of this thread used to finally get it working...
quite frustrated...

Have you tried flaking with odin one click or the drivers from designgears thread in dev section? Also try uninstall drivers and go to advanced and install those drivers manually. Let met know if helps if not we can try something else.

Try a diff USB cable too.
Mine did the USB not recognized thing due to a faulty cable.
This happened to me a while back. There was only one way I was able to get to download mode. See if it works for you -
1. pull battery, count to 10
2. reinsert battery, DO NOT TOUCH ANY BUTTONS exept to follow the next step
3. When I would hold down the vol Up and vol Down together for several seconds, the screen would blink. When the screen blinked I inserted the USB cable. Bam - download mode.
Hope it helps.
edit: well, this is coming from the "phone ! computer" screen. sorry
Able to get unto download mode... I will try the different cable idea in the morning... well... it is morning so in like 6 hours lol... thanks I'll let you know...

When connecting to Odin. Odin should be open and running prior to putting your phone into download mode and attaching to usb.
It was at the time...
...but I just got it working =] can't believe I went a month and a half without my Captivate and finally bought another just because of a bad cable =\
Any clue as to hat might have made the cable bad? It still charges phone and looks fine =\
Thanks 41LY45 for the cable suggestion and everyone else too for everything... now to root this new phone... (wont be easy this time Rogers and I guess its NAND locked or something)
Thanks again!

How I solved USB soft brick.
I had something similar, and have been searching for hours to find the following sollution:
Source: http://android.modaco.com/topic/309961-usb-brickrickrolledb0rked-fixed/
...
Also, SD card functionality has to work. For this, do 'fastboot oem enableqxdm 0' in fastboot mode.
Steps involved:
1. Find out your CID. Go into fastboot mode, and do 'fastboot oem boot'.
The log will say something like the following:
Code:
#INFOTAG:Ramdisk OK
#INFOTAG:smi ok, size = 0
#INFOTAG:hwid 0x0
#INFOTAG:skuid 0x21F04
#INFOTAG:hero panel = 0x0
#INFOTAG:engineerid = 0x0
#INFOMCP dual-die
#INFOMCP dual-die
#INFOTAG:mono-die = 0x0
#INFODevice CID is not super CID
#INFOCID is HTC__E11
In this specific case, the CID is HTC__E11.
2. Get the following mtd0.img from here or from here: mirror provided by SgtDavePwnage.
Edit this image to the CID you found above with a hex editor.
3. Get flash_image from here or from here: mirror provided by SgtDavePwnage.
Move this to /data/ , and flash the modified image using:
"/data/flash_image misc /data/mtd0.img"
You can move both mtd0.img and flash_image by putting it on your sdcard, and issueing the following command in a terminal emulator:
'cat /sdcard/flash_image > /data/flash_image'
'cat /sdcard/mtd0.img > /data/mtd0.img'
You might have to do 'chmod u+x /data/flash_image' before you run the commands (or chmod 755 /data/flash_image)
4. Repeat step 3 a couple of times if it doesn't seem to work well.
5. All done! Reboot, you should have normal usb connectivity. Post your 'fastboot oem boot' log and intermediate steps if it fails.

After that I followed the r4-legend-root Step 1 and skipped step two by placing Clockworkmod as update.zip on the SD.
Recovery Vol up + power. And I was back in the game. { I lost that other game while typing this }
It took me a while to learn all this. In 24 Hours 5 hours of actual work and frustration. But I'm There.
I hope this helps you as it did me.

Hi there, I'm new here but I have been following this forum for a long time.
Here's my problem:
I own a LGP990 with DJANGO rom. apart from the random stuck in the DJANGO loading screen which required me to reinstall it, it was all working fine.
Until yesterday, when I plugged it to recharge. The battery charged for a while and then got stuck for hours when almost done.
I unplugged it and try to turn it on but since that moment it always gets stuck at LG logo screen and when plugged it doesn't display any battery charging. I then tried to start recovery to reinstall from zip as I did every time it got stuck in the django loading screen, but recovery does not start.
No problem, I thought, lets smartflash/nvflash a stock rom and i'm good to go. Wrong, the phone won't even get recognized by windows, though I installed the driver several times (disabling driver signature as well) and running it as admin; i tried different driver versions, different usb cables... It does not even play that background sound when plugging usb devices...
I'm using windows 7 32bit.
That's it, I have ran out of ideas... anyone got one? (besides sending it to assistance, since warranty is voided)
little edit: whenever i plug the battery the phone start by itself!

I meant to enter recovery. If your phone turns on when you put in the battery, the power button is stuck in a connected position so to enter recovery remove the battery, press the vol- and then insert the battery. If you get your phone to enter recovery and reflash the rom I will tell you what to try to fix the issue.
1.)remove battery
2.)press volume - and volume +
3.)connect phone to pc via usb
4.)download apx driver
5.)(go to device manager install manually apx driver, select the folder where you downloaded and extracted apx ini driver file
6.)flash using nvflash

mmmmhhhhh..... change usb port, change cable, reinstall the drivers. other than that I am at loss
AIO tool has an option to install Nvflash driver. Its the last option in a different color.
Or you could try to reinstall LG driver. I just downloaded the latest driver from lg support tool today. It works fine.
And be noted that you have to hold down both volume up and down while plugging the USB cable to enter nvflash mode. Holding vol down while plugging the cable in will enter boot loader mode which is not the same thing. Remember to remove the battery first of all.

hey...ur problem solved??
Hello I have an unlocked Lg optimus 4x hd software version 4.1.2 JB. I recently successfully rooted it but CWM said there wasn't one available for my phone on the rom manager app so i found one. I would post a direct link to it but apparently im not allowed to yet.
I realised that this was realised almost a year ago after the fact, this probably is what messed my phone up.
I installed it and ran it, when my phone rebooted it was stuck in a boot-loop. I can still access the default android recovery screen and I tried hard resets and clearing the caches but I'm still stuck on the LG logo. My computer still says that its installing drivers when i plug the phone in but it won't let me do any thing. I have looked around the forums and the solutions i found aren't helping me. Any help would be appreciated.

great it looks like im nearly there but where you saw three ports active and one actually downloading i only saw one active but it wasn't downloading, i feel as if though it could work i just need a little more help. Sorry if this is wasting your time...
simple, run windows enabler to ON, connect phone in S/W mode, go to device manager -- modems --- LG xxxxx *13 ... and the number is the port ... for me i have 13 port selected .. or you can try one by one ... if one fail ( RED --- FAIL TO OPEN) then try another ...
Thank you everyone!!
It worked thank you guys soo much!!
Hi there,
I flashed the wrong cwm as well on my gf phone. (she's going to kill me)
Anyway, the All-In-One tool does'nt help me. I can perform the root (which is useless, because I cant even boot) but I cannot anything. I think it's because no sd is mounted.
Code:
Choose The Number :-7
Now connect your phone with "Debugging" enabled .
Drücken Sie eine beliebige Taste . . .
Copying files ,, Please wait ...
failed to copy 'O4X_OR_R.img' to '/mnt/sdcard/O4X_OR_R.img': No such file or dir
ectory
sh: cat: /mnt/sdcard/O4X_OR_R.img: No such file or directory
rm failed for /mnt/sdcard/O4X_OR_R.img, No such file or directory
I can't even boot into the S/W mode. I just get a grey (or sometimes blue) screen.
Please help!
try to take the battery out plug the phone with a cable on your computer. Insert battery again. Flash firmware
edit: it seems like your all in one tool doesn't find the image.

flash a firmware using LG-KDZ-UPDATE-TOOLS. Search them in google,
Follow instructions found in the internet. I can give you a link but its in german. There is probably an english equivalent here somehwere.
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
Hi
I've been reading all the topics in here and trying many methods, but now im desperate, so i dediced to post here
When i try to run my phone the red text appears: [LG-Security] Error: Boot Image Signature!
I've tried to run http://forum.xda-developers.com/showthread.php?p=35971349 this guide, but when i plug off my battery i cannot get into s/w upgrade in my p880.
When the battery is plugged in I can run s/w upgrade, but my computer doesn't see the device.
Is the phone bricked?
Can i do anything to ressurect it?
EDITroblem solved - still don't know how, but after 5000th reboot it is just working without any other bugs etc...
it's bricked, you tried to install custom recovery without unlocking bootloader?
you can revive it using that tutorial. leave the battery in in order to get to s/w upgrade screen, but before that, you need drivers (and if your computer isn't detecting it in s/w mode, the drivers aren't installed)
It seems that you didn't install the proper drivers on your PC as it doesn't recognize it.

Yes, your device is (soft)bricked, and yes, you should be able to recover it. Try the LGMobile Support Tool. Run the tool and plug in your phone while holding down the volume down button (with or without battery). If it doesn't see your device, make sure you have all the latest drivers for your device installed. You can find them on LG's website. Then, try again and once found you'll have to force an update. You can find that option somewhere in the top right menu's. Then be patient.
I seriously doubt whether you have properly searched the forum, or Google for that matter, though..

Anyway - thank you again, and sorry for the time you lost
