Hi there guys,
I was wondering if anyone could upload a copy of their u boot images. I am running a P768 on V10E Taiwan, it was originally on V10B, i believe this one. Could anyone send me their u boots please. Im pretty sure the KDZ version does not matter, as long as it a P768 file (I have flashed V10E, V20A and used Online recovery flash back to V10B and my phone is always shown as U2)
Edit: Ignore any references to U2 device - lelus has mentioned that U2 is the L9 motherboard code - it is not a different device - nothing to worry about.

backup your current xloader and uboot and ask someone with rooted jb p765 (non-branded) to do the same
Code:
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
then you restore nonbranded xloader and uboot
Code:
adb shell su -c busybox dd if=/sdcard/external_sd/p2.bin of=/dev/block/mmcblk0p2
adb shell su -c busybox dd if=/sdcard/external_sd/p1.bin of=/dev/block/mmcblk0p1
if something goes wrong and your phone doesn't boot you can restore your original files by using fastboot
Code:
fastboot flash x-loader p1.bin
fastboot flash u-boot p2.bin

If the backup doesn't appear, mount the 'system/dev/' folder as R/W and retry.

Good day.
I was hoping that somebody kind enough would post a download link of u-boot and probably x-boot backups of LG L9. I have P768 flashed with
JB rom (telcel mexico). Everything was fine at first, until I started the omap4boot procedure where I accidentally flashed Prada's u-boot into my phone. Mine was bricked now. It cannot be turned on and there's no way to put it in Software upgrade mode. I even tried to hardware reset it but i does not work. I think the same thing happens to Donk165.
Thank you.

Good day again.
I just tried to bring back my phone to SW upgrade mode just like what was instructed on the link but it didn't work. I removed the battery, connect
the phone to PC via usb, and then press and hold the Vol + and power button together for several seconds and still nothing happens. The only obvious thing happening is whenever I connect the phone (with or without the battery) to the PC is I keep hearing windows making noise as if the device was detected and then gone, then back again. This kind of behavior was also mentioned in LG L9 fastboot (omap4boot) forum. Also, somebody in the fastboot forum mentioned he accidentally flashed L9's u-boot with pradas and then after unable to recover his phone like mine.
Probably, LG L9 P768 was really brickable and probably Im not the only one who was bricked when prada's u-boot was flashed over.
So for P768 owner's be warned. Be careful unlocking bootloader using omap4boot as the instruction provided there was not clear about not flashing u boot.
Anyway, I would like to thank cmahendra for trying to help.
S/w upgrade mode is a part of uboot so yes you need at least semi proper one in order for it to work. You can safely flash xloader and uboot from http://forum.xda-developers.com/attachment.php?attachmentid=1846304&d=1364667944, which are from ics 760, that will bring sw upgrade mode back ,restore v20a with offline method which will also restore original xloader and uboot

Good Day:
Thank a lot Lelus. You're a big help. I will try to flash these files later.
Thank you for posting here lelus, I will flash the files from P760 when I try out JB again in the next few days.
Just to clarify, my phone was not bricked, I just thought my lack of working fastboot on JB was because of using Omap4Boot.
So are the xloader and uboot all the same throughout L9s? It was posted above, but it wasn't confirmed.

Technically the uboot or/and xloaders are different for each model even carriers , the difference seems to be purely cosmetic besides ability to unlock booloader. I'm talking about p760 765 768.
Btw if your phone is working fine,there is no reason to flash x or u especially ones from ics

I have 2 phones so I am willing to give this a try even though I may brick it.
Here is my device status: P769BK 10g rooted.
I need to know exactly how to attempt the bootloader unlock. Do I need CWM? What software and steps to flash? etc.....
Ok I'm about ready to give this a go. I've familiarized myself with fastboot, and will flash u-boot and x-loader thru fastboot. Does anyone have an original u-boot and x-loader so I can unbrick my phone when this doesn't work?(P769)

Here seems to be original files with patched files. And IDA working files... Take a look in archive.
Ok I flashed patched bootloader thru omap4fastboot. Upon flashing u-boot and x-loader the phone is bricked won't turn on or anything. Was able to go back into fastboot though and flash the original files back. Its back working again, however when booting up the screen is mirrored(just picture not touch) it stays inverted like this until I lock and unlock the phone after that its fine until next restart and a very minor inconvenience until I can get a hold of P769 u-boot and x-loader from some kind person. So confirmed not working at least on P769.

@Tablechair
Great you have tried without fear and congrats for recovering back phone when it failed.
But tell me, was your P769 already had the mirror issue due to earlier P765 flashing? Or it appeared after above procedure you performed and now screen working fine?
What happened was:
I did not have the original bootloader file from P769. I only had the unmodified files that payday was working on. I suspect he had files from another device variant P760 or something. The screen mirror thing I haven't experienced before. I believe if I can put the proper files back it will be fixed. So, I really need someone with a full P769 dump to share with me u-boot and x-loader. The screen problem goes away shortly after boot, but I've noticed another symptom when I try to flash using the method in your thread the tool hangs after trying to contact the phone. It was very late though I could've overlooked something even though I've used that method before I will be trying again tonight after work.

Now I start to have a picture of the pioneers in tech
Quick question: is this your primary phone or just a fun/backup phone?
This is my primary phone. Thank you for your kind words but, it was actually a really foolish thing to do. Next morning after this I tried a few times to flash a kdz to get root with Lelus's new method, but it does not work something got really messed up from flashing stuff in fastboot. Now after attempting to flash kdz I get security error again, and I will most likely have to send my phone into LG for warranty service. I'm not upset about it though, if I saved a few people from trying the same and bricking their phone I am happy and it was worth it.
Unlocking the bootloader on p769 is DIFFICULT, the most difficult part is working with the touch screen which is wonky during this process. I highly suggest that we wait for LG's latest Jelly Bean for p769 instead of doing this, but if you are wanting to experiment like me, then read on.
Please note that every boot will ALWAYS have a mirrored image after doing this procedure.
First and foremost, thanks to Lelus for helping me through the process. Second, you need to be very familiar in flashing KDZ offline with this procedure (thanks cmahendra)
http://forum.xda-developers.com/sho....xda-developers.com/showthread.php?p=36351786
1. Download this link to get p760 20B Europe open and flash it on p769 using the KDZ offline method.
http://csmgdl.lgmobile.com/swdata/WDLSW/LGP760/ANEUWH/V20b_00/V20B_00.kdz
2. After flashing you will notice you have two issues...Mirrored Image and Wonky touch screen. Mirrored image can be easily remedied by using a mirror to read the screen better. The Touch screen issue is the most difficult because after flashing 20B, we need to enable USB debugging in developer options. (thanks cmahendra)
Wonky Touchscreen:
This is how I got through the wonky touchscreen. Imagine putting a line in the middle of the screen crosswise (or like dividing the screen crosswise), you have to top screen and bottom screen. The Imaginary line would be the bottom of the top screen and the BOTTOM of the bottom screen (like the bottom screen's bottom is in the middle of the screen and the top of the bottom screen is in the bottom of the whole screen). It takes some practice but you will get it.
Make sure you face a mirror with your phone to get around the mirror imaged.
3. OK, now you have to go to Settings --> Developer Options ---> and tick USB debugging (You can also tick "Show touches" to make it easier).
4. LET YOUR PHONE STAY ON FOR 30 minutes or more (Very Important or you won't be able to unlock your bootloader). Then connect your device to PC and type "adb devices" and make sure your p769 is seen by the computer. Then type "adb reboot oem-unlock" This will reboot your device and send you to a "mirrored" confirmation screen. Basically just press Volume UP button to confirm unlock... then it will send you to fastboot, you can just press the power button for 10 seconds and reboot.
5. After rebooting, you need to flash 10G kdz back, in my experience, the offline flashing method by booting to SW mode did not work... It hanged up at 15% and said my device is not connected to USB. The only way for me to flash 10G KDZ back was to boot in JB (mirrored) and then instead of Emergency Mode, I used DIAG mode while the device is connected to PC. Only then was I able to flash back to 10G.
6. After flashing 10G KDZ, you won't be able to boot. Turn it off and do a hard reset (Power button + Volume UP + Menu Button).
7. Upon reboot from 10g, you will still have the mirrored image, but if you press the power button and turn it back on, the mirrored image will be fixed. Then comes the wonky touch screen. Beside from having the wonky touch screen you will notice that the whole left and right side is also inverted which makes it very difficult but doable with practice.
8. In 10G, we need to enable USB debugging again, then root the device with this procedure
http://forum.xda-developers.com/showthread.php?t=2171243
(Remember to use DIAG mode in reflashing 10G for the second time in rooting the device)
9. After rooting the device, we need to fix the touchscreen with this (Post #24)
http://forum.xda-developers.com/showthread.php?t=2182867&page=3
and go to post #24..
That's it AGAIN, I highly suggest we wait for JB for our devices instead of this.

Goodluck
Awsome
I'd add ,disable your lock screen before flashing jb
Awesome work :victory:
By the way, you might want to bold the warnings involved with this process so that it stands out better. I have a feeling some people won't read the entire post and dive in without knowing exactly what they are getting into
I have successfully overclocked our GPU to 384 Nenamark 2 scores from 32.7 jumped to 36.9 Do we have a working CWM with our proper mount points?
I also noticed the OC'd the GPU at 384, I cannot OC the cpu to 1200 via kernel.
Awesome work!
I completely agree with waiting on an official update to JB.. I personally don't see much of a point in unlocking until we can boot into a custom ROM.
I've given up on this device - but with a hopeful update to JB and a hopeful official unlocking method on the horizon I may hold on.

yes, using omap4boot
Mine is now unlocked too. Back on 11a with fixed touchscreen. You weren't kidding about the touch being tricky. Took me longer to get into developer options than any other step I took the recovery.img from the jellybean root/recovery thread and flashed it in fastboot and now have working recovery too. It's mirrored like you said but it's easy enough to navigate like that. Restored data from the backup I made before starting, it's like nothing happened.

I have flashed the original x-loader in my unlocked device and it seems OK so it is definitely the p769 u-boot that is locked. I also noticed that the screen is still mirrored at boot and I believe this is due to the screen size differences of the p760 and I we can find a way to fix the screen size in u-boot, then we will get the mirror image fixed.

Here is a little script I put together to fastboot L9s with ability to flash/restore ics xloader and uboot (p760, p765, p768, p769) jb (p760)
*I've only tested it on Win 7, but it should work on Vista , not sure about XP and 8
Very useful post about installing the drivers
*Some phones may need a different timing, 4 seconds won't work, worth to try between 0 to 4s and see what works best

#1 is just a general fastboot, you can put whatever (boot.img, recovery.img, etc) you want to flash via fastboot in "yours" folder - type: fastboot devices and you'll see if your phone is recognized
and the rest is mainly for recovery, ics xloaders and uboots work nicely with offline flashing method also several people mistakenly soft bricked their phones with omap4boot by flashing prada files which can't happen with this tool
For me general fastboot works on ArchLinux. But I only put recovery with it...

of course if you have functional rom and unlocked bootloader you don't need it
Hi there, its been a while since I tried fastboot again, but I have good news. Fastboot worked on my P768 using this method, I selected option 1. Then I was able to send recovery to my phone and then root the phone using a flashable SuperSU zip! 'adb reboot recovery' takes me straight into CWM!
I have some questions though.
Is fastboot permanently on the phone like it is on the P760 now? or do I have to use this program each time to send fastboot commands?
Does this mean that I could potentially flash a custom rom to my phone now? I know all the custom roms out there are not for the P768, so I will get camera problems. But is this the missing piece of the puzzle for custom rom development/testing?
Thank you lelus for this great tool!

Fastboot is definitely there but something doesn't get passed along during adb reboot bootloader or oem-unlock and phone just reboots instead of booting to fastboot.

I'm pretty sure* you can use Android Kitchen to replace these files in latest Cyanogenmod zip with ones from p768 jb and have camera working.
*i might be wrong

great, keep it up @donk165
Thanks. When I find the time. I'm going to make a guide for unlocking the boot loader, pushing CWM with fastboot and rooting.
I'm not confident in building CM, but I did see another user who was willing to try but was stuck with a locked boot loader. Hopefully together we can get the ball rolling for P768 development.

i think we need help from devs to port camera from official p760 cm to p768 maybe @markolino631 can do it for us, seen we had unlocked bootloader and able to push cwm using fastboot.
I got a P769 from a friend and it is total dead,black screen, no SW update or hard reset key combinations works, only can fastboot and shows a mirrored LG logo , on top right it says V0.5, but unable to flash x-loader, u-boot or recovery, always show the error "remote partition does not exists", i tried to erase the partitions with fastboot but still the error is same. does somebody experienced the same? they call this phone un-brickable

My guess is corrupted nand or partition table.
What did your friend do to the phone?
Well I don't know, he just sent me that it is not booting. Is there any tool / way to initialize the nand?

Just heads up, the fastboot files are from lg prada p940 which has somewhat different partition setup but it's definitely worth trying as a last resort if nothing else works.

Hi,
I'm not a newbie to Android by any measure, but this is my wife's phone, not mine (I have a Nexus 4) so I'm not familiar with a lot of the LG stuff.
Anyways, I rooted her phone to get rid of some of the bloatware and the stupid Qslide thing, and also to edit the build.prop so Netflix will have the Chromecast button. I had deleted quite a few bloatware system apps, and rebooted, everything was fine. I deleted a few more, then edited the build.prop. Rebooted.
Now it shows the LG logo, but then the screen goes blank, but is still on (you can see the backlight) and never boots. I only removed a few more of the LG and Tmobile apps and edited the model and manufacturer in the build.prop
Do I have any easy options to fix this? Or do I need to flash the KDZ?
Flash kdz then install cwm then backup the stock ROM THEN do your mods. Every time every phone. Good luck

Yes, offline flash the kdz. Always backup your rom whenever you so something like that.

If it's just the build.prop causing it not to boot, you can flash (with fastboot) the boot.img for the kdz you are on. Look at my signature on how to extract it.
If that doesn't work, flash the ice cream x & u partitions for p769 in fastboot, and then run offline flash

Thanks for the suggestions guys. I've tried the offline KDZ flashing it, but I can't get my computer (tried two actually, mine and my wife's laptop) to do anything once its in the S/W Upgrade mode. I used the method previously to update her phone the JB when Tmobile pulled the update. Since then it downloaded the most recent OTA. But anyways, I don't know why it wont work. It just continally tells me that my phone isn't connected, even though I'm using the latest drivers and the phone shows up correctly in the device manager. It's driving me nuts since it worked previously!
Any ideas?

Sorry I didn't break it down enough for you. You have to get fastboot up and running. Jellybean does not operate when starting in S/W mode, that's why you get the connection problem. Now ice cream, does operate when starting in the S/W upgrade mode. With fastboot you can flash everything you need to get the offline flash working. These three links are all the info you need.

Factory LG mobile support tool has an option to "update recovery" in top right menu. This will download latest factory rom via internet and reflash phone in software update mode to reset everything.

Works well.
might have to set phone into software update mode by pressing vol up and then inserting usb cable..

Ok, I got the timing down and fastboot seems to come up, but after I can see the logo on my phone with the v 0.5, the script just says < waiting for device >. Thats where it should flash the ICS xloader? Or am I missing something and I should flash the JB images with fastboot? Where can I get the images?

No, you shouldn't. I think you will get bootlooped. I have no alternative at the moment. I'm stuck like you. May I ask, how exactly did you enable updates? Mine is on JB but each time I try to update it says "Phone not registered*

So noob here, found this when trying to figure out how to update to 20y. I have 20k currently.
I am rooted, just went back to stock rom, tried update and ended up bootlooped, got out of it by following an xda post by Weston Madsen (can't link, haven't made enough comments to allow me), and am now back in stock wanting to update.
If you want this file, I have it copied on my comp, let me know if anyone could use a link
Still don't have the file. Tried messaging DrDanTm too... Bump for visibility...
