P768 security error + not recognized by PC - LG Optimus L9 P760, P765, P768, P769

Hello everybody!
Searched all the threads but none seems to cover all my problems. I'm newbie here so i'd need detailed help.
So, what do I have? I have P768, came to me like this for 20 euros with problem that on every boot it says "Security Error". I know that this one is not strange to you. I've installed Mobile Support Tool and LGMobileDriver_WHQL_Ver_4.0.3. When I go to Options > Upgrade Recovery (of course i switch phone to S/W upgrade mode - VolUP + Power button when inserting USB), but phone not seems to be detected. Also, it is not showing up when connected via USB in device manager. I had antivirus, tried (known to me) everything - but no luck. So, I am thinking about restoring phone to it's stock firmware.
Any help, suggestion, link to other thread would be welcome!
This is my first post.
Best wishes from Serbia!

I followed the steps given on that thread
My pc shows new device found ANDROID. Device is not getting detected
But on this step in cmd

it shows < waiting for device >
i too got such problem.
while holding down back +Vol down connect your phone to pc .It will enter into emergency mode.Then your Computer might detect it.
Can anyone of u help me ???? My phone is still stuck with Fastboot mode
Basically on a windows machine you download kdz updater and uncompress it as it is a zip file.
Download from here.
This is what I did on an xp laptop.
I had to down load the drivers from the official lg site. when here you enter the code that is on the box the phone came in or under the battery.
Chose the your county and laguage from the drop down box at the top right of the dialogue box. Then from the middle you can choose the drivers. For some reason I had to find the files and click on them to install the driver.
Ok once you decompress kdz updater there are three seperate files to work with. 1. windows enabler. 2. msxml.msi 3.KDZ_FW_UPD.exe
You will also need to download the right file to restore with,You can find it with google.
Please check here the The_ERROR thread wich explains it very well:
[ROMS] Original LG Firmware list.
Install msxml now.
Now you have to boot the phone into rescue mode. On Lg Optimus One turn phone off even if it means taking out the battery.
Press power - volume up - back (this button is next to the home button).
Connect to usb now.Computer found new hardware and installed four drivers.
Then open device manager. Left click my computer - properties - device manager. You need to disable the lg modem driver. Left click on it and disable.
Now launch kdz updater. There will be a drop box on left set to 3gspt or similiar. on the right drop box set to diag. The long box just above the info box with a file at the side lets you browse to find restore file. e.g. V10a.00.kdz.
Double click the button below and let it do it's thing. Took 15min. My phone shut down and came up with an error at the last minute. Anyway I rebooted and all was good.
Everything was the way I left it. Just had to re-root.
My only real problem was getting the kdz installer to see the phone.
After installing the drivers restart pc. If it finishes quickly and just before saying finished it says phone not found try removing all phone related drivers including nokia pc suite and the lg suite and remove and reinstall the drivers.
Hope this is of some help to you.
Finally, Recovered my phone by flashing KDZ through Emergency mode.. No other method worked..

I had the same worries coz my pc did not detect my device at all..
I was trying to get pass the Fastboot mode.. But in the cmd when i tried to erase and re-install recovery it said waiting for device.. Luckily and finally after many tries i could enter emergency mode. Only then the phone got detected but fastboot didnot work there.. The Only way out was to Do the KDZ flash. I flashed the indian GB V20b and did a hard reset now. Flashed recovery and for now have left it with the stock rom..
I wonder now this problem arises due to custom roms.

this problem was cuz didn't perform the steps carefully.
This can called bricking but not fully . As it can be recovered.
Bricking is when your phone is as useless as a brick.

[Q] Thl w100 bricked

My phone it's bricked, I rooted my w100 yesterday and to celebrate I installed the ifont app from the market, but at the third change didn't reboot any more, I have searched for the rom but seems to be very new...

its pretty easy, you can use the motochopper tool, instal the mtk6589 driver and connect your phone to the pc, then hit the runme.bat file and follow the instructions, very easy!
Here you have a very simple and good post that surely will help you.

You must be the absolute first to brick your w100.
Did you succeed installation of kok's rom ?
I bricked my phone too...
First I installed a partitioning app to my device, my plan was to merge the two inner partition into one.
Then i become frozen boot.
After that I tried reflash with sp Flash Tool, I made a "format" and a reflash, and now the W100 is in boot loop.
When I try to do a factory reset in recovery it says: "Mount /data error"
Could you guys help me please? What the hell can I do now...?
I've succesfully unbricked my THL W100

Hi everyone,
Few days ago, I've also bricked my THL W100... My mistake was one of the most stupid one: instead of click on Download in SP Flash Tool, I click on Format and accept the operation without reading the warning message. Result: first boot I got the white THL logo in bootloop, and second attempt give me only a black screen with only a faint red light on the front LED.
I've read many threads about unbricking MediaTek based devices, made many manipulations without success. I've even disassemble my device in search of a secret 'test point' dedicated to full memory flash.
Unbricking THL W100 in far more simple than all this. You'll need one of the 'THL W100 original ROM'. I've choosen the May 16th edition (130516) on NeedRom (http://www.needrom.com/phone-roms/thl/thl-w100/). And off course, you'll need SP Flash Tool, also available on NeedRom.
Unpack the Rom files, launch SP Flash Tool, and load Scatter file, and press 'Download' button
The 'deep memory flash mode' require activation of the 'MTK DA USB VCOM' driver. To activate this mode, you'll have to:
1) disconnect the battery
2) keep the Vol+ down and connect the USB cable (without battery)
These are the main operations...
For my problem, I've tried to flash:
- the whole Rom except Preloader... but it fails,
- the whole Rom including Preloader... but it fails too,
The solution came by using first 'Format' function, and select 'Format whole flash' option, before flashing Rom as previously described. But, I used this format function with classic flash connection, e.g.: connecting the THL W100 to the PC via USB cable without the battery, and inserting the battery (and no use of Vol+ button, off course).
Be carreful: before trying this kamikaze procedure, try to unbrick your device by simply flashing the Rom without/with Preloader.

Afraid I don't understand...
The format is what you had done to brick it in the first place isn't it ?
So you needed to format again using 'Format whole flash' option ?
Is that correct ?

True: I've bricked my device by using 'Format' with the option 'Format whole flash except Bootloader". At the first reboot, I got a THL white logo bootloop. After second reboot, nothing but a black screen and a faint red light from the front Led. I've tried 'Download' and 'Upgrade' SP Flash Tool functions to reinstall ROM(s) with or without 'Preloader' partition: got lots of sybilin error messages, and correct download.upgrade achievements, but my device remains bricked.
I've also tried 'Format whole flash except Bootloader' function + immediate Rom download, but it fails... until I use 'Format whole flash' function (USB cable connected + battery insertion) and immediately after whole ROM (130529) 'Download' (no battery inserted + Vol+ pushed + USB cable). First boot took about 4 minutes... but everithing works after that.

Hi everyone!
When I got my w100 I tried to put an other ROM with sp flash tool, flash tool process completed perfectly but when I tried to boot my phone, the pone it started up but the screen only showed white lines. I even heard the sound of the boot.. But screen remained black with white and other colours lines.
I tried to flash it again with diferents many ROMs..W100_130912_backup_131001-214504, W100_130504_ForFlashtoolFromReadBack_130605-170952, ThL.W100.130701.JBV2.HD.EN.COM.8P32_MT6589.
Even though the process got complete, the perfomance of the phone was the same as I said.
As I got tired of flash it once and again, then I followed your advice, so I did a "Format whole flash", I got it, but after I tried the "Download" I always get the same error, after first red bar it's 100% sp flash tool always shows the same message:
BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032)
[EMI] Enable DRAM Failed!
HINT:
Please check your load matches to your target which is to be downloaded.
Now when I tried to do whole format or download, I got the same error.
I tried by vol+ pushed + cable usb and cable usb conected without battery then I put de battery. But still the same result.
I'm starting to think that can be a motherboard damage or samthing!!
Can anyone help me please!!?
I found the solution!!
I did it by using Windows xp!!! Then the error message disappeared!! And i've got my phone working!!

Brom error: S_ft_enable_dram_fail (4032)
Hello,
my THL W100 arrived yesterday and i was immediatelly interested in some custom rom so i began flashing it not knowing properly, what i was doing, so firstly i ended up in boot loop, then completely bricked with device refusing to boot (black screen).
I tried recovering using SP Flash Tool these builds, but nothing worked for me:
thl.w100.130529.jbv2.hd.en.com.8p32_mt65
ThL.W100.130701.JBV2.HD.EN.COM.8P32_MT65
ThL.W100.130802.JBV2_.HD_.EN_.COM_.8P32_MT65892
W100_130504_ForFlashtoolFromReadBack_130605-170952
I also tried using different versions of SP Flash Tool (.119, .139 .150), but all showed error BROM ERROR: S_FT_ENABLE_DRAM_FAIL (4032)
As said here before, tried on Win XP and Win 7 64bit and it showed same error.
So then being despred for several hours I actually dig up a lot on internet and found up some information:
1) There are apparently some hardware revisions, according to beginning of serial code:
BFYSG94W - Rev. 1
BFYSG9410 - Rev. 2
But my phone has CFYSGM4W - maybe its a new Rev. 3?
2) Based on many other mtk6589 phones having the same problem, you should look for firmware released by date of manufacture. It should be written somewhere, but I didn't find any information on device no package, so I decide to look for latest.
3) The phone shows up in device manager as "alcatel RNDIS" under network cards, I had to manually update the driver selecting "Preloader for Flash SP.Flash" .ini file manually from a disk. It may tell that the device may not work or something, but don't worry, reconnecting it shows up as MTK USB Port under COM and LPT ports and it should be fine.
4) I also had to disassemble to device and short LCOLO test pin to ground - here is the original post with image http://forum.xda-developers.com/showthread.php?p=44208574#post44208574 I soldered a single wire of hdd ribbon cable to lcolo, the other side being wrapper around USB cable. I flashed without battery, shorted all the time. The Flash Tool immediatelly discovered the device, when the lcolo pin is shorted, then when progress bar turned from red to violet the MTK USB Port device changed to 'MediaTek Preloader USB VCOM Port' so the preloader was owerwrited and phone successfully flashed back to factory state.
(before you lose your warranty try connecting usb > inserting battery or connecting usb without battery + holding volume up, it does practically the same job)
5) There are lot of stock roms here - http://www.needrom.com/phone-roms/thl/thl-w100/
So finally the version that worked for me was: ThL.W100.130912.JBV2.QHD.EN.COM.V01.8P32-kol
I even managed to get CWM working, (used same scatter, checked only recovery and doble clicked and selected recovery-cwm-6037-w100-130912).
To make it easier for people having the same problem I put up the things that worked for me and uploaded it, includes:
ThL.W100.130912.JBV2.QHD.EN.COM.V01.8P32-kol
SP_Flash_Tool_v3.1316.0.150
recovery-cwm-6037-w100-130912
and drivers for ADB and Preloader for Flash with SP.Flash

I also received a THL W100 with a CFYSGM4W serial today.
I flashed a different stock rom to it and it refused to boot (just showed some black and white lines). Google led me here and your package worked great . I tried a few different roms but the one you provided seems to be the only one to work.
Thanks

[q] softbricked? i think?

So I recently wanted to load a custom rom on my p769.
Unfortunately, I tried to flash a rom without actually having the bootloader unlocked (thought i did?)
Now i'm forever stuck at the "LG Security Error" screen.
I can't seem to do anything else! :'(
The only other mode I can boot into is S/W update screen (holding volume up and plugging in usb cable).
I tried to get to another mode I read about (vol up + vol down then plug usb cable for "download" mode, to no avail)
Anyway, once I do get it into sw update mode, I can't seem to do anything either way, when i try to list adb devices, none are listed, when i try to use lg mobile tool, it never connects, when i try to use kdz offline update tool, it doesn't see the phone, it just keeps trying to connect, the log freaks out at "_IsConnectedPhone Call", and just keeps trying to "connect" to phone but can't
Am I totally screwed here?
What can I do? Any help appreciated!

You're on JB, right? KDZ offline flash tool cannot detect phone in JB. you have to flash ICS x-loader/u-boot then that tool can detect your phone. please visit http://forum.xda-developers.com/showthread.php?t=2292828
For LG mobile support tool problem, it need to download rom from LG server. Have you remove/comment 1-2 line that you add to hosts file? You said it never connect that mean it don't see your phone?

I've tried this as well, but I don't know if i'm doing it correctly
I installed the 'drivers' it needs (following the readme file) when it shows the "unknown/other" device (the part where you have to catch it in device manager).
After this, I run the start.bat, enter 5 and hit enter, i unplug my phone and hit any key, then i plug it in as it says and it does it's thing, then i wait for 4 seconds when it begins to say "waiting for device", i put my battery in and it just stays there, waiting for device
Can you help me figure this out? Am I doing something wrong?

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager
whenever i try to run the kdz offline flash tool (if i'm using the right one), it still doesn't detect the phone as connected, doesn't even try, just errors and tells me to connect to usb port and restart or exit
what am i supposed to do once i'm in fastboot recovery for my phone?
should i comment out the 2 listings i added to the hosts file? should i NOT be running shttps app? which kdz offline flash tool should i be using? (currently trying: UpTestEX_mod2_marwin.exe)

i think i'm making some progress, thanks for helping so far!
anyway, i'm able to get fastboot on my phone (i think?), the screen on the phone shows the flipped LG logo and at the top right it says 2.0 fastboot (flipped of course)
but, what am i supposed to do here?
i see the 2 omap devices listed on my device manager

You should run start.bat and select flash ICS u-boot/x-loader for P769
When it finish, reboot you phone to S/W update mode and try to use UpTestEX_mod2_marwin.exe to flash your P769 kdz again to restore your phone.
Maybe I miss something about P769 model, please search in FAQ forum many people have this issue, and most of them have fixed it.

How to fix partion problem !!!
After countlss hours of messing with the LG P769 This is how i got into S/W mode to work !:laugh:
ASSUMING you know how to install fastboot drivers there are instructions on the forum ...so follow those guide note fastboot drivers work best on windows 7 windows 8 was giving me hard time ...
1.install fastboot drivers
2.run lelus script at the same time hold vol+ button once the script shows the OMAP device close the script and immediately put the battery back in .The LG phone will boot into S/W mode !
Make sure you write down your imei or serial number AND make sure battery is fully charged . then
Now simply use the LG software tool or the KDZ offline flasher look around the forum for how to guides
Thats it

Then try enter in lelus fastboot mode, ad then flash x-loader, uloader, boot.img and recovery.img from stock rom for your device type model. Then repeat steps 1 and 2
Where can I find the lelus script?

Sorry for reviving such an old thread, but oh well...
Your procedure doesn't seem to work with my device. Just to make sure we are using the same driver packages, can you post a link to the fastboot driver you have successfully used?
My L9 is always showing this "partition doesn't exist" error message, no matter what I try. Lelus's script seems to do the job and the phone is detected as a fastboot device, and can even be detected in LG Flash Tool (using a 910K cable), but flashing will stop after a little over 2 minutes, because the phone disconnects. During all of my attempts, the screen stays black.
Any hint?

Then you need a Technician with a Octopus Box to repair your partition table...

Can you boot into recovery? We now have a custom recovery for locked bootloaders (and CM roms). If you can get into recovery, I would try some adb commands to mount the partitions.
No, no recovery. Just to make sure that I'm not doing it wrong, what is the key combination to boot to recovery?
I have also tried:
Code:
fastboot boot some_recovery_image.img
It says ok, but the phone just hangs at the black screen and becomes undetectable as a fastboot device, until I pull the battery. So, unless the some_recovery_image.img is unsuitable for my P760 (which may be!), there is something seriously wrong I think.
Or maybe I can try the same command with the custom recovery for bootloader locked phones... Where can I find it?

Your EMMC partition is wiped or fried... you really need a JTAG service or a Box like octopus because your L9 is Hard-bricked...
Thanks for your opinion. Yet, I still want to hear from others.
I'm running into more and more problems with the L9 as their me grows.
-Fastboot doesn't work under Windows 8.1 and 10, but under the now obsolete(for me) Windows 7, unlike my other devices, which are fine with Win 10.
-ADB seems to work, but requiring the device to be still able to boot.
-I always boot to recovery from within Android as long as the L9 ain't bricked. After a failed rom install, during which the sd card failed(could no longer write or be formatted afterwards, the last time stamps of files and folders were set during the failed install) I discovered a problem with TWRP(Artas182x's and Edwin's), which may have been present since a long time: Trying to invoke TWRP via keypress will brick the device!
So, if my P760 no longer boots, there's only download mode available, sort of the final line of defense.
-There's sort of a trick if even download mode fails: After a failed attempt unplug phone, force switch-off, if the phone is in brick state. Then switch on, force switch-off again, and only then attempt download mode again. And have patience while holding down the vol button, it might take up to 20 seconds for the phone to switch itself on into download mode. (A single forced powerdown will cause Fastboot NOT to work the next time)
But I'm absolutely clueless about the recovery issue, for now TWRP is semi-working, can only be accessed via Android, as long as the phone is fully working.
W/o Fastboot, I now have flashed stock rom several times and rooted it with Kingo rooter just to be able to run Flashify to install TWRP. If Flashify is the culprit for the TWRP issues, I could need a recommendation for a better working app.

Tried OMAP flasher ? It needs memory configuration file in order to work with our device
No, I didn't. I have sold the phone for spares.
Inviato dal mio LG-D855 utilizzando Tapatalk
I never needed the OMAP drivers and tools. As they are ancient, they will probably make even more problems with newer Windows versions.
I could by no means invoke Fastboot on this device with Windows 8.1 and 10, Seven worked. So you had to go for Download Mode instead to recover to stock rom, then root with the Kingo tool, then install TWRP via Rashr or Flashify, the most time consuming way to recover from the frequent bricks.
And the LG Flash Tool 2014 always needed several attempts to get the job done. The latest official recovery tool from LG works in D/L Mode, but will always download the rom image anew.

[Q] Stuck at LG logo

Hi all!!
Yesterday i tried to install android 4.4 but the procces didnt succeed, it stuck at. LG boot logo. So i decided to restore my backup in ckockworkmod,it started the process then stopped at the phase "restoring /system" . I waited about a half hour, and because it didnt take the much time before, i took out the battery. I read somewhere that formatting the system partition in cwm could help, so i did that. Then i retried restoring my backup. It stuck at the same phase. Later i downloaded the official kdz, and decided to flash it. I could bring the phone in update mode, but the process stopped at 15% at lg update manager.
At the moment i can get into clockworkmod, but cant restore /system . The update mode is also okay. I dont know that fastboot works or not. I havent tried it yet. Please help me thanks in advance
@trapistasajt
You will need to get fastboot working and use lelus's fastboot script to flash the "u" and "x" loaders for the device and then perform the offline or online flash
http://forum.xda-developers.com/showthread.php?t=2292828
Also as you found out you cannot flash custom roms without ulocking the bootloader first and you cannot use the L9 CWM bootstrap recovery for Locked Bootloaders, too flash custom roms.
try this online flash methode with B2CAppSetup

i had the same probleme and i fixed it .
My bootloader is unlocked. I tried the fast boot method, but it doesnt go further than "Waiting for omap...." . So, i couldnt go into fastboot (probably my fault). Yesterday i sent it to the service. If they notice that my varranty is void (because of the unlocked bl) and send it back, i will try it once more. I would be very thankful if someone could write a noob friendly-fastboot guide. As i read, lots of people are struggling with the same problem. Thanks in advance!!!
You have to use LGMobile Support Tool (Install drivers from it first) Then enter in download mode conecting the phone to pc pressing vol+ and the rest its automatic.

It didnt go further than searching for "omap device", so i couldnt load fast boot, as i said. my phone is still in the service
If they 'll send it back to me, because of unlocked bootloader, i wil try it once more. Any suggestions?

I dont know about fastboot.
LG Mobile support tool let you download the correct drivers. Then connect your phone while u keep pressing vol+ and it enters in SW Upgrade mode. Then just click "additional features" and "upgrade error recovery"

It shows something about firmware ir will restore. Ir will flash the latestbfirmware from original carrier release.
For example i actuallybhave v20L but my original carrier only released v10a. It will restore to v10a
None of them works, other ideas?
This fastboot method worked for me in 5 min, pay close attention to the instructions and it works!

Spent days with LG update tool which if you read the log has no url for files to download.
Good luck!
I got my phone back from the service. They didnt repair it, because my varranty is void. I tried the methods mentioned above.
First, I tried flashing kdz, (with the solution for post-jb problem), but i couldn't get into S/W mode, which was available before the service.
Second, since i couldn't load S/W mode, the LG upgrader wasn't successfull, too
Third, fastboot still not work.
I am sure, that im not the only person with this problem, since it happened during installing @artas182x 's JB 4.4 rom. Please @artas182x or somebody write a noob-friendly guide/suggestion which may help to unbrick my beloved phone. Thanks!!!!!
