I already rooted and add CWM; however I can not unlock the bootloader. It keep on giving me an error message of "Unknown Error, maybe due internet connection issue please wait and try again later". Not sure what else to do... Please help
my suggestion: Go to the asus website, download the firmware for whatever version you are on, put it in the root of your prime and restart.
after it finishes restarting do an update, it will detect the file you just added and let you revert to stock through that file.
after its done reinstalling everything back to stock try unlocking again.
The asus installers tend to be really sticky about customized stuff on the tablets when you try to update. most of the time when i try to OTA i have to use this meathod to revert to stock first. Good luck!
I just download the apk from the Asus site. I installed it and the same error message happened.

silly question but you have a good internet connection? perhaps its failing because its not able to send the signal to asus and get the key in response?
If that doesnt work i know one of the root tools had an unlock function built into it, im not sure how it differs from the stock unlock tool i know it would do the same thing but maybe through your compuers internet signal instead of the primes? Sorry i cant remember the name of it right now, if it comes to me ill post it.
I do have good wifi signal. I keep trying and same thing happened.

Do you currently have CWM in your PRIME?
If yes, I think the bootloader was unlocked?
I installed CWM through Rom Managers

Can you boot into CWM? If you can then you're unlocked. If that is the case I would bet you are getting the error because you can't unlock twice
When you reboot your prime and if you don't see a message on the top left corner saying something 'unlock' then you're not unlock. When you reboot and hold the power button and volume down to get into recovery and you're getting the dead android you're not unlock.
When you run the Rom Manager to install CWM it will ALWAYS says success if you have root. It doesn't actually mean it worked.
It just show me the Android guy laying down. I did unlocked it before I sent it in for repair. Not sure if u can unlock more then once

When I reboot there is no unlock message. I can't get in to CWM when I reboot. I still try everyday using the unlock tool but with no success.

Think I found the answer to unlockable bootloader...
I can't say this will work for everyone but this worked for me just yesterday.
If you don't get the three icons when booting into bootloader you are not unlocked...those three being "Wipe Data", "USB", and "Android". Using the modded ViperMod tool (http://forum.xda-developers.com/showpost.php?p=25508554&postcount=52):
Unroot the Prime
If you have already downgraded to .15 great. If you have not do so now.
After the downgrade has completed, on your Prime go to "Settings" then go to "Backup & Reset" then a "Factory Data Reset". (Warning: All data will be erased).
After the reset has completed go back through the ViperMod tool...first root, then unlock (If you have done it correctly the Asus Unlock Tool will show up in your app drawer.) Then install CWM.
You should now be ready to flash your custom ROM.
Hope this helps. I have a bald spot from scratching my head over this one.
ok. giving a try tonight.

Im not sure if you finally fixed your issues but I am having the same issue with my dads tablets. I could really use some help.
He has a TF201, build number -- iml74k.us_epad-9.4.2.11.1-20120118
This is whats going on
--When I try to boot into recovery I get the android guy on the ground with the red triangle
--When I try to unlock the device I get "unkown network errors please try later"
--When flashing the newest CWM trough Rom manager I get "blob signature verification failed and the reboots normaly
--Theres only 2 options in bootloader "wipe" and
--Also when I try System Firmware update i get no updates available
--Ive tryed viper mod with no luck, I was able to "unroot" and "root" the tablet but I cant do anything else, theres the option to downgrade to .15 but I need to upgrade and I cant.
little bit of the back story is: he bought tablet new, had to update to ICS, then rooted the device somehow (he doesnt remember), he thinks he had CWM before but Im not so sure.
Im completly lost and I have no ideal what to do next, please I need some help.

Maybe somebody can help me with this. I went through all the steps to unlock the bootloader and root the phone using Lokifish Marz guide(very helpful by the way). and now when you boot the phone up in the top left of the screen is the word unlocked.
However, when I go through the process of moto-fastboot. it acts like it's working just fine,erase recovery...OK, Sending Recovery.... OKAY, writing Recovery.... OK. but when I go to boot into recovery (power+volume down, scroll down to Android recovery and hit volume up) I get the Triangle with a !.
To make matters even more confusing, is I have got it to boot up to CWM. I did a full back up on internal, including web top and I thought I was good. I had to run to the grocery store so I booted my phone back up for the time being and went and did my errands, came back and booted into recovery(with the above way.) and bam! triangle, !, android guy.
I've done this a couple times. I'm assuming I'm doing something wrong however I can't seem to find anybody else that has had the same problem. I've held of on trying to flash a different rom, so I'm still running stock rooted.
I'm running Android Ver. 2.3.4 Build 198_6 and I've tried flashing a coule diffent versions of recovery3 including the one that came with Root-Unlock-Recover.
Anybody have any ideas?
I also have the same problem with my motorola photon. i went thru the steps
to unlock the bootloader it said it was unlocked i checked to make sure i was rooted with root check and it said i was. but when i power the phone on and boot i can see android recovery but when i select it the menu is not there just
a triangle and the android symbal, then i have to pull the battery to restart
it does and the phone seems to be working ok.
Well it make me feel better that im not the only one. What tools did you use to unlock your boot loader?
Sent from my MB855 using Tapatalk
What version of stock did you guys start with? I think there was an USCC OTA that IIRC locked up the boot loader on the Electrify.
Sent from my MB855 using xda premium
Started with Android Ver. 2.3.4 Build 198_6 , its the same one that's on there right now. and it's saying my boot loader is unlocked, I actually went through the fastboot unlock process again to check and it said it was already unlocked. Although I just tried flashing twrp recovery and the same thing happened, so it seems to be behaving like it flash's the new recovery but it doesn't.
Strangely though, I've been able to get into Clockwork Mod once or twice, but as soon as I reboot, and to go to recovery it takes me to triangle !, is that just stock recovery/bootloader? So basically CWM is a one time use then back to fast-boot to try again and again.
maybe I should look into re-locking and just going with a boot-strap?
So with some more Tinkering it seems I can get to ClockWorkMod so long as I don't reboot my phone all the way.
if I flash clockwork mod. pull the battery and boot into CWM it works fine, but if I fastboot reboot all the way it goes back to stock recovery. I'm beginning to think the boot loader isn't really unlocked even though it says it is.
Anybody else heard of this?

Are you still on the factory kernel or did you upgrade to the DoomKernel? I found the reboots happened with the DoomKernel but have not had a single reboot since I went back to the factory kernel.

Im still on doomkernel, I don't know how to go back to normal, this is my first Android device haha I only got it because it was 169.99 on a one year term since I work for Rogers in Canada. I could fix my iPhone easily but this is proving to be a little more challenging
here's what you need to do:
backup whatever you can
Re-lock the bootloader. (using the instructiones at htcdev.com/bootloader)
download and run the RUU file from htc.com/us
it will update the version of the device and will clear all the data from it, including root access and kernels
now that the device is like new again - root it if you wish to, but do not flash the kernel by doomlord. its not stable.
Okay so to relock bootloader do I just plug it in and go to fastboot and use the command fastboot oem lock? I will try when I get home from work, I tried this before but got an error when I tried to use the RUU installer I cant remember what it was exactly, but ill post results when I have them

Correct. Relock, run the Ruu and then root and install the doom recovery. I've done everything but put his kernel back on (not the insecure kernel, that gives you root) and am very pleased with how my Jetstream functions. Still needs a good custom ROM though.

For immediate access, upgrade to FileFactory Premium. Alternatively, you can try again shortly.

it says the rom update utility cannot update your phone please get the correct rom update utility and try again
there is a chance that there are two different RUUs. one for Rogers and one for at&t.

Ive tried all three roms found in the dev section! The first two were exes and didnt work and when i tried to flash the zip i get an error that says FAILED Remote: 12 signature verify fail -sigh
if u'r having crashes you need to flash the RUU from Rogers. RUU means Rom Upgrade Utility. it's an exe file published by htc/rogers.
you need to d/l the file, connect the device to the computer and run it, after relocking the bootloader.
the ROMs that are in the development section are very raw and pretty much neglacted by now. do not try to flash them, it will probably only make things worse.
Okay, so where would I find the Rom from HTC. I work for Rogers and we do not provide them.
try searching the forum for a rogers version.
if you can't find one - i'd try resetting the device first.
long press the power button.(20 sec).
than turning it on while holding Vol. down. there you can find the factory reset.
if that takes you to the recovery try wiping all the data (cach,data,delvik whatever)
if nothing works, try the link below. maybe it'll work on your version.

Dumb question, but how do you know that you are not unlocked? Have you tried to install CWM or TWRP? If I recall, when I ran the unlock tool all that happened was that I got "the device is unlocked" on the splash screen, it rebooted then back to stock exactly like it was before. Nothing was different.
Sorry to thread jack but do unlocked people always get "the device is unlocked" on the splash screen on every boot? I have got the impression from screenshots etc. that happens every boot. I only saw it once though, now my splash screen has no text on it when I boot (unless I run CWM )

Hi All,
After a failed attempt to root my L9 769, I have an issue where when the phone is turned on, it does not boot, it goes to a screen with the LG logo and the words "security error" beneath it. The phone then powers off. The only thing I have access to on the phone is this screen and the software update mode. I used the offline flash method in my root attempt. I am sure I screwed up in the process. I have scoured the internet in an attempt to resolve this, but I have yet been able to. This seems to be a fairly common problem when a root attempt fails, however I cannot correct this.
Things I have tried:
Fastboot: I try to run fastboot, but it stops at waiting for device.
Offline flash: I tried the offline flash method, but the tool freezes at 15% saying the device cannot be found.
Online flash: The tool recognizes the phone but sees it as being up to date. I try to use the recovery option but it locks up at analyzing the phone.
I am at a loss. Any help would be greatly appreciated.

Some help on how to install fastboot
Did you install the omap4430 driver twice?
Open an elevated command prompt and type
Code:
SET DEVMGR_SHOW_NONPRESENT_DEVICES=1
devmgmt.msc
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",
"lightbox_start_slideshow": "Start slideshow",
"lightbox_stop_slideshow": "Stop slideshow",
"lightbox_full_screen": "Full screen",
"lightbox_thumbnails": "Thumbnails",
"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
Then open the Device Manager and see if you have the omap4 driver installed twice (in two locations)
Note: In Device Manager click the View tab and select Show hidden devices
If you don't see the omap driver installed twice, do this
Select the "other devices" and start deleting/uninstalling all of the devices you find here (I think the device you are looking for is "lg u2" but not 100% sure)
Once you have uninstalled all of the unknown drivers you found, run the start.bat again and follow the directions to flash the x & u img's (for your device).
Now go back to device manager and find the new unknown/other device created (should be lg u2) and install the omap4430 like you did the first time.
After you have done all this, rerun the start.bat and hopefully it will work for you.
Another thing, If you do see the omap driver installed twice, then it has to be your timing when you enter the battery. Keep trying different times to enter the battery
example. wait 1 second and enter battery, if that doesn't work wait 2 seconds then enter battery and etc.
Good luck
No luck yet with connecting to fastboot, I will give this a shot and report back. Thank you.
You were absolutely right, the issue was with having multiple drivers. I followed your steps and restored my phone to life. Thank you so much.

@kuma82,
Before I start, I had NO IDEA how crazy the L9 was! I've rooted/unlocked/custom recoveried/custom ROMed 4 other phones without any major set backs prior to hitting this wall.
Also, this is my daughter's phone and I'm really took a lot of precautions before starting.
Here is what I did prior to attempting to wipe (factory reset) and install CM 10.1 (here):
Device model: P769
[was] rooted
CWM Recovery [was] installed
Stock JB (T-Mobile US) ROM backed up (full nandroid)
I was concerned about the many submodels of the L9 and verified both in the about phone within the ROM settings as well as what's printed/etched below the battery under the back cover. Both checked out to be P769.
I ran `adb reboot recovery` and then proceeded to wipe/factory rest from within CWM recovery. After this, I installed the ROM zip from the external sdcard. It failed the update script's assert of ro.product.id and would not install. OK, bummer, I'll just restore the nandroid backup. Nope. It was unable to restore /system and so now I really got concerned. I then found the weirdest thing of all. After seeing what is asserted in the update script for the ROM zip, I ran getprop for each of the properties it checks for and got back the Prada 3D "p940"!
Well now I felt like I was in a world of pain, so I decided to hack the update script so that "p940" would be accepted. Well now the install went fine without any errors reported. I proceeded to flash the latest gapps for 4.2.2 and it too installed fine. GREAT! Now for the system boot.........
From that point on, I've been stuck in LG Security Error land
I was able to get the special fastboot to connect (after many failed attempts) by selecting option 5 for ICS x & u flashing.
Could someone be please be kind enough to help me get my daughter's phone back to some ROM? I'm alright with even stock right now. At least then she'll have a functioning phone and I could even extract apps to restore from the CWM nandroid I made via Titanium.
peace.

To install custom rom or CM10 you need to unlock bootloader first. You should follow kuma82 in his post above to flash back stock rom.
The security error is because you didn't unlock it (sorry to hear that). Just flash with fastboot ice x & u for p769. Then put your phone in s/w upgrade and run the offline flash.

The security error is because you didn't unlock it (sorry to hear that). Just flash with fastboot ice x & u for p769. Then put your phone in s/w upgrade and run the offline flash.

I swear I read every link you posted above and still could not figure out what: "flash with ice x & u" is. I downloaded the fastboot zip and ran start.bat and selected option 5 for ICS x & u for p769 and that got me an inverted LG fastboot screen. I was also able to then choose option 1 for fastboot which dropped me into an empty yours directory.
It was midnight and I had at least 8 browser tabs open to various xda posts, but I still couldn't figure out what I needed to do with the start.bat next.
Thanks in advance. My weekend is dedicated to solely fixing her phone

Hi All,
After a failed attempt to root my L9 769, I have an issue where when the phone is turned on, it does not boot, it goes to a screen with the LG logo and the words "security error" beneath it. The phone then powers off. The only thing I have access to on the phone is this screen and the software update mode. I used the offline flash method in my root attempt. I am sure I screwed up in the process. I have scoured the internet in an attempt to resolve this, but I have yet been able to. This seems to be a fairly common problem when a root attempt fails, however I cannot correct this.
Things I have tried:
Fastboot: I try to run fastboot, but it stops at waiting for device.
Offline flash: I tried the offline flash method, but the tool freezes at 15% saying the device cannot be found.
Online flash: The tool recognizes the phone but sees it as being up to date. I try to use the recovery option but it locks up at analyzing the phone.
I am at a loss. Any help would be greatly appreciated.
Thanks,
J

I've been wanting to try this: go to your computer and check your device manager and disable the LG drivers then try the offline flash again. Kuma way works but it's very long, found this while I was reading but never tried for our phones. Same problem though as updating stops at 15 %

Another thing, more than likely, after you flash with the r&d tool you will need to do a hard reset because you flashed cyanogen. Also, you will still need to root to fix the touch screen.

Yeah, I was able to repeatedly get the inverted LG fastboot screen and see everything you saw in device manager as well as successfully get `fastboot devices` to show (echo) the device. I even tried `fastboot flash recovery p4_769.img` with the file linked in post #3 and it flashed without error.
Here's my problem: What do I need to do now that I have a working way to run fastboot commands? Is there a recovery image I need to flash (stock)? Is there a boot image I need to flash? Or, is there some other fastboot command I need to run?
I'm assuming the advice you're giving me is to ultimately get a stock ROM back on her phone. Is that correct?
I'd really like to unlock the bootloader so that I can do what I know with CWM: backup, wipe, restore, flash, etc... If that is something I can do from where I'm at now, I'd prefer to put the effort in to that. If this darned 'Security Error' splash message must be resolved by getting back to a stock ROM first, then I'm game.
Final request for clarification: Am I still needing to "flash the ice cream x & u boot for your device (in fastboot) to get the offline flash running again"? If so, could you please provide instructions for that step? So far all of the steps linked here have been to get Windows drivers sorted out and fastboot working. I've got that now.
Thanks again!

Okay, did you get all your info about unlocking the bootloader from carloswii5 video? So you had flashed 20b kdz right?
You gave me a hand full Lola, but I'm help you out. It get is going to take me some time to give you a guide, but I'll give you everything you need today and yes, you need to get back to stock.
I'll send you another link on how to use fast boot manually. Plus it has the images for ice cream. But hold up

THANKS!
Her phone had the stock TMOUS jelly bean ROM that we received OTA. I had only rooted her phone previous to my CM10.1 fiasco attempt.
So I've never flashed anything (successfully at least) on her phone. All of my previous android experience has been on 3 nexuses (One, S, 4) and my current HTC Sensation. That means I've only unlocked one bootloader that didn't support the fastboot oem method
I'm an experienced dev with the entire weekend to "play" with my daughter's p769
I also promise to provide lengthy posts in the Optimus L9 forums to help any future people from soft bricking any more devices.

This will tell you how to use fastboot manually http://forum.xda-developers.com/showpost.php?p=43642515&postcount=21
The system image is to big to flash with fastboot, sucks.
1. Use the above to get back on stock (you need 10g kdz).
To enter s/w upgrade remove battery. Hold volume up and enter USB cable, then put the battery back in.

UH OH... The "volume up" method isn't working on this device. I posted more details about it here. I'm beginning to think I may need to return the phone. I never thought flashing a ROM zip in CWM recovery could brick the phone. When I restoring the CWM backup also failed (when I at least was in CWM recovery which now is inaccessible), I freaked.
P.S. - I'm all out of thanks for the day. I think you got the lion's share though
Could someone help me with this issue?
I unlocked the bootloader of my p768 a while ago, and then I sent it to the carrier service, because it was having some signal problems.
I read that, once you unlock your bootloader, you can't lock it again, so, when I got it back, it was kind of restored and today I tried to flash Clockworkmod (.img file) and when I tried to reboot it, it said "Security Error", I followed this guide:
http://forum.xda-developers.com/showthread.php?t=2470248
And when I connected the phone to the computer, and it says that the device already has the most recent version.
What do I do? Any suggestions?
Thanks

Hi @speakerstick
You need to update the recovery in the LG mobile support tool and then it should work.
Look in the top right screen and select "Support Tool Options Menu" and then select "Upgrade Recovery"

I've tried, but when it says it's uploading it to the phone it suddenly disconnects and I have to do the same process again, but the same thing happens.
What do I do?
Thanks

Are you using the stock cable? If not, do so.
Have you made sure nothing else (NOTHING ELSE BUT THE NECESSARY) is connected to the other USB ports? Unplug stuff.
Do you have the drivers needed? Uninstall, redownload, reinstall.
Have you tried on another USB port?
Do you have any idea, based on the logs the program generates, about what might be wrong?
I've done it! I finally was able to do it. I uploaded it with the battery, I know the guide says you shouldn't but it worked, now... Does anyone know how to re-root the device? I unlocked the bootloader a while ago and then I sent it to service, but how do I "root" the phone again?
Thanks!

Maybe you should try doing it the same way when you first unlocked the bootloader? Just a thought....lol.
