Got my new LG L9 and, after upgrading to V20B via OTA, I decided to downgrade to V10A to get it rooted (this was before I discovered this thread :/).
Here is what I did:
- I successfully used the KDZ_Flash-Package_LG to downgrade.
- Had to hard reset, then the phone booted fine.
- Rooted using Bin4ry's method
- Installed some L9RecoveryInstaller_1.3.0.apk for CWM (I think this is where I might have f***ed up?)
- Got into CWM recovery just fine, then flashed the lates CM nightlies (from here) +gapps (or maybe this was stupid?)
- Rebooted (wiped all data, cache & dalvik)
Now the phone is stuck at the "Securty Error" screen. The situation:
- Hard reset doesn't help....
- ...but I can get into the S/W screen just fine!
- The devices COM port shows up in device manager
- ...but not the ADB
The LGMobile Support Tool does recognize the device just fine and I can start the phone update process, however, my Internet right now is dead slow, so I'd be waiting for 8 hours for the download to complete (with a chance of things going wrong, again).
I hoped I could flash using the offline KDZ flasher again (as I did previously). However, it keeps complaining that my phone is not connected. I assume this has to do with the fact that the ADB is not initialized?
Anybody knows a way out of this? How to get the ADB up while in S/W mode?
Or at least some feedback on where exactly I made the mistake, so I can learn for the future?
Edit1: Note that I did make a backup of the phone in V10A state, so getting back into recovery would also help!
Edit2: Could this "fastboot" thing help? If I got the phone into fastboot mode, what specifically could I do to unbrick?
Cm won't work without unlocked bootloader. SW is a bit flaky in JB. What you need to do is get p1 (xloader) and p2(uboot) dump from same variant phone as you have. These dumps need to be from ICS then you have to use fastboot to flash them. S/W mode should work fine after that. I'll update my post with more details when I have more time.
Try getting p1 and p2 from someone first
Thank you so much for your response!

Who would be so kind?
Edit: I played around a little and I already manged to get into fastboot mode following this thread. So all I need now are these p1/p2 dumps? Is there any chance on finding this on the web, in case nobody can provide me with some, here? Also, with "ICE", you mean "ice cream sandwich / ics" version of android, right?

Yes, ics. I don't think you can find it on the web. I'll post instructions how to dump p1&2 later.
R: [Q] LG L9 / p760 stuck at "security error". How to get ADB up?
Hi, I can provvide x-loader and u-boot from ICS but I think you need the boot.img (kernel) because you flashed the cm's kernel with locked bootloader and that caused the security error.
Anyway with LG mobile support tool you can configure an http server to download the kdz from your PC (VERY fast).
As soon as I get home I will post x-loader, u-boot and boot.img from ICS

Thank you again for your response! So the backups posted in this thread would not help me, right? I need dumps of unrooted p1/p2's...
@sguerrini97: - almost missed your response , thanks for getting back at me, and thanks for your offer to help me! I'm looking forward to get this fixed again
You are welcome
Here is a boot.img from p760: https://dl.dropbox.com/u/95188513/Android/boot.img
And here is the x-loader: https://dl.dropbox.com/u/95188513/Android/x-loader.img
They are from V10H. Unfortunatly I can't find my dump of ICS' u-boot, anyway I think you only need the boot.img.
Once you get in fastboot mode, run this command:
Code:
fastboot flash boot boot.img
This should fix the security error...
To get adb working you can boot into LG's stock recovery if you didn't flash CWM from fastboot ([vol+] + [home] + [power]).
If you flashed another recovery (not the 2nd-init recovery, but a real recovery) here is the stock recovery.img: https://dl.dropbox.com/u/95188513/Android/recovery.img
You can flash this with fastboot too:
Code:
fastboot flash recovery recovery.img
Keep us updated on your situation
- flashed your boot.img:
- still security error
- flashed both your x-loader.img and the recovery.img you provided:
- still security error
- tried to get into the LG recovery mode anyway:
- YES! ADB Interface in device manager!
- Tried to flash V10A using LGMobile Software Tool (was the only image I ever managed to get offline):
- used "emergency" phone mode
- went through "ANALYSIS" and "DOWNLOAD" without problems...
- ...but now is stuck at 4% of UPDATE for 10 minutes now already
- (log appended)
I'm still having the update open. Should I pull the plug? What to try next? Try again? Different PhoneMode?
Again, thank you so much for your support!

LG Mobile support tool is the easiest way..
You should download the last kdz for your IMEI (the version that the tool can find) and place it in:
"C:\shttps\www\swdata\WDLSW\LGP760\XXXXXX\VX0x_00\VX0x_00.kdz" and set the http port to 80.
(Replace Xs with your kdz info, you can grab them from the kdz link).
You should put only one of the two lines in the hosts file, I don't remember whick one but you can try..
LG Mobile Support Tool will connect to the internet but it will "download" the kdz from your PC, it will be very fast.
Sorry for my englesh
Okay, I'm not sure if I'm still doing what I'm supposed to:
To which version of the LG tool are you referring? The original one? The original one in combination with the fake KDZ server?
The folder you are referring to doesn't seem to exist.
Whats with the port? I never set any port before in the KDZ procedures...
Otherwise, I think I get what you mean with the path:
WDLSW/LGP760/ADEUBK/V20b_00/V20B_00.kdz
This file I am already downloading in a DL manager for some time now... (should be finished in 2h )
Next problem: I just tried to go through the regular update (without any offline tricks). It now asks for S/N and IMEI data (which I happily provide). Then update stops immediately:
Updating is not possible any longer due to a fatal
error while the LG Mobile Phone Software Update

If that procedure doesn't work, follow my previous post
Sorry but flashing boot.img will get you nowhere, system partition has been overwritten by cm, best you'll get is bootloop.
I don't know if lg intentionally broke sw mode in JB or why it doesn't work but that's why your phone isn't being detected by lg tool or kdz flasher and you won't be able to fix security error with plain adb.
to dump:
adb shell su -c busybox dd if=/dev/block/mmcblk0p2 of=/sdcard/external_sd/p2.bin
adb shell su -c busybox dd if=/dev/block/mmcblk0p1 of=/sdcard/external_sd/p1.bin
to restore
fastboot flash x-loader p1.bin
fastboot flash u-boot p2.bin
after that software mode will work and your phone should be detected by either lg tool or kdz flasher
@Lelus: You seem to be right... It looked so promising, but indeed, both following the instructions from the GUIDE and the workaround sguerrini97 posted, something always fails...
@sguerrini97: You already helped me sooo much, but do you think you could create those dumps for me? I'm kinda lost here :crying:
Now I've got the PACMAN rom, x-loader and u-boot are the ones from JB, I don't know if they will work..

I'm not sure, either... this is mostly new to me, and I know just as much as I learned today (which is already a lot ).
Theoretically you could use xloader and uboot from ics of p765 or p768
Two questions:
Where could I look for people that could help me?
Why is my CWM backup I made from my ICS install (after root, before flashing cm 10.1) not helping?
I have the following files:
Code:
.android_secure.vfat.dup
boot.img
cache.ext4.dup
data.ext4.dup
nandroid.md5
recovery.img
system.ext4.dup
Is system.ext4.dup not what we are looking for? (.dup = dump?), system = x-image? Most of these files are pretty small, though...
You need a backup in .tar format to restore it from adb, you made it in the new CWM format and I don't know if it's possible to restore it from adb. Maybe if you flash my x-loader and my u-boot you will have unlocked bootloader to flash a real recovery to restore it.

You mean your current JB x-loader / u-boot, right? I'm willing to try, could you upload those files?
x-loader: https://dl.dropbox.com/u/95188513/Android/JB/x-loader.img
u-boot: https://dl.dropbox.com/u/95188513/Android/JB/u-boot.img
CWM recovery: http://download2.clockworkmod.com/recoveries/recovery-clockwork-6.0.2.9-p760.img
You have to flash everything from fastboot:
Code:
fastboot flash x-loader x-loader.img
fastboot flash u-boot u-boot.img
fastboot flash recovery recovery-clockwork-6.0.2.9-p760.img
Then try to enter in recovery with [vol+] + [home] + [power], you should be into CWM.
Greetings, I have a problem with this phone, when repairing the IMEI does not appear on the screen, although in the software it appears, in the reading of the software used.

The easiest method to read the QCN file, is using the software PSTTool1_725, using the Developer Mode option, with the password: 123456.
And with this programming code *#*#248#*#*
, you will have a menu in view, but you enter the USBMODE TEST line, and select TEST_MODE, with that operation you can activate the diagnostic port.
With the PSTTool1_725 in the system manager tab you will find the way to read and restore a QCN file, then images.
include the link to download the PSTTool1.7 setup software together with the USB drivers Sonim Smart Phone USB Driver Diag_1.4.
