Thanks for putting this guide up, I was stuck at the point where the LG Mobile Phone Software, would say that my device is not connected with USB. But I know it was because I had it all connected, it showed up in the device manger and was recognized by fastboot. I guess I just didn't have the right images to be compatible with flashed onto the device. Thanks to you putting all of this together, it finally worked again. Thanks a lot life saver!!!!!!!!!!!

Undesired lines in LG optimus L9 P765

I opted this method to unbrick because i was getting the same security error. And successfully installed all the 3 images. But it was after installing these the real problem came in. Now i could enter the bootloader but it appeared to be a set of multi colored lines. And when i tried to replace the installed recovery img with CWM img, the security error problem again came in. I am trapped in a situation that i have to get access somehow to CWM or any alternative. Can someone suggest me some good alternative for lg p765? or is there any work around for this?:confused:

Well i see this is ancient post, but anyway this is the proper metode to flash L9 if you are stuck in bootloop or something similar.

First if you installed any softwares or anything else go to control panel programs and features and delete everything then,

Follow this here : https://xdaforums.com/showthread.php?t=2797190

Don't choose emergency mode just leave everything to stock, hold vol up and connect usb cable it will go to download mod and install drivers(but first in flashtool2014 thread you have drivers which you have to install)

Press normal flash (leave to korean and all that you will be prompted for language as soon as the phone boot)

And then press start wait until 100 %(phone will boot itself)

and Boom everything is done.

EDIT : Of course you have to download proper .kdz file for your device.

Hello.

I was in the process of upgrading my HTC One from 4.2 and successfully unlocked the bootloader. But thereafter my phone just constantly reboots. It shows the HTC splash screen for about 10 seconds and the reboots again.

I am able to go into the fastboot screen (see screen shot). But when I select Recovery, the phone gors to the next screen - displays "Entering Recovery" - and nothing else happens thereafter.

Can anyone please help? Have looked at other such questions and tried but nothing has helped.

[One (M7) Q&A, Help & Troubleshooting] THeHopelessPainter:
I'm not sure you did ever flash a custom recovery!

1. Put your phone in fastboot from the bootloader meny. You already did this while rooting, so you got it already!

2. In your "SDK-tools" folder that you used while unlocking the device, put [nameofyourrecovery].img I recommend you to install TWRP 2.6.3.3, as it is the best one for flashing kitkat and lets you do this if you wish :) I cannot give you a link as I am a new member, but search google for TWRP 2.6.3.3 and you will find it. Make sure it is .img and not .zip!

3. While in fastboot, open a command prompt in the ADB folder.

4. To flash your custom recovery, type

Now give it another go ;)

Does not help. Used 2.6.3.3, the flash process went fine, then Recovery displays "Entering Recovery" - and then again bot loop.

Many thanks. I used your suggestion and rooted as per #9 in this post:

[One (M7) Q&A, Help & Troubleshooting] nkk71:
Not really, don't know much about your model. You'll need to find a ROM compatible with your device; if it doesnt specifically say it's for your device, then most likely it isn't!!

I think there's a Maximus HD ROM for your version, but i have no idea where.
[One (M7) Q&A, Help & Troubleshooting] Jcc1dls:
Did you..

Aside from flashing a recovery and rooting your phone, did you make any other modifications or flash any other partitions?

If no, then wipe Dalvek cache from TWRP. Boot into TWRP and select Wipe. Select advanced. Select Dalvek and Cache. Wipe power down. then power on and see if it will boot.

i had a similar problem last week with a One, a friend bricked his One by flashing "???" Dont know exactly whar he has done.

The phone had boot loops all the time.

my solution was:

- connecting the phone with the usb cable to my pc.

- started the phone into fastboot usb mode

- started cmd at my notebook

- change to the directory which contains adb and fastboot

- execute: fastboot erase cache

- restarted the phone

the phone starts normally into ARHD 40.3

perhaps it works ...

[LG Optimus 4X HD] noone1101:
Hello There.

First of all, is it possible to install both PAC-man 4.3 ROM and SlimBeam 4.3 using MultROM?

If Yes, how to do this correctly/what am I doing wrong?

I have TWRP 2.6.0.0 and MultROM installed. Tried different combinations and nothing work.

I'm not much into this stuff, so as far as I could go I have investigate the issue of kernels and kexec, but as I said, my knowledge stopped on knowing that there is such thing, and secondary ROM can be installed with different, separated kernel.

Thanks for interest.

I thought that it would be helpful if I write what combination/order of instalation gives what result, so here it goes:

1. Installing SlimBeam, and then PAC: E: Error executing update binary in zip 'tmp/mr_update.zip'

2. Installing PAC, and then SlimBeam: Installation complited correctly, secondary system(SlimB) loading forever with PAC boot animation - probbably because of kernel?

3. Installing PAC and then SlimBeam with seperated cernel: (In Multiroom when booting SlimB) Error Kexec-hardboot support required to boot this ROM...

In this case I'm guessing that patching this kernel could help, but it's superadvanced for me ;)
[LG Optimus 4X HD] Dexxon:
The kernel of your primary ROM needs to support kexec. I don't think this is true for the pac nor the slim kernel. You will have to flash a custom kernel on your primary ROM.
[LG Optimus 4X HD] noone1101:
Exactly.

Idk either how it looks like with pac as secondary, because of such mentioned problems.

I am on a good way to finding right kernel for that and trying to flash it, and test if it works.

Ty for reply.
[LG Optimus 4X HD] Bogeyof:
Your Problems consists of 3 things:

1. U need a kernel with Kexec-Support for the primary Rom to be able to boot secondary rom with other kernel. If u use same kernel for both rom, u dont need a kernel with Kexec-Support

2. To flash the kernel for secondary rom, u need a repacked kernel with ramdisk from destination rom, anykernel wont work, cause u cant flash it on secondary. It writes with "dd" direct to partition and this is wrong way for secondary Rom. So u have to choose a repacked kernel for secondary...

3. The script in most install.zips for 4.3 roms contains symlinks written over more than one line. These scripts wont work with multirom installer (TWRP MultiRom), so u have to modify script, extract from zip, write all symlinks and all other commands (which are broken into more than 1 line) in 1 line and copy back into zip. Install will work now (modification is for "Error executing update binary in zip 'tmp/mr_update.zip').
[LG Optimus 4X HD] Flying_Bear:
the alternative to problem 3 is to install a rom, do a backup, install the rom you want and restore a backup as second rom. thats how i did it, noob-way :)
[Nexus 5 Q&A, Help & Troubleshooting] k8826324:
I've noticed a very subtle but strange behavior on KitKat generally. When I unlock my device, there is usually a smooth window animation that leads you into the home screen. However, if you access the camera by swiping right on the lock screen, the next time when you unlock the device, the animation seemed to be gone and just enter the home screen really quick. I set the window animation scale to 10x in developer option just to see if I was right and I found out that indeed when you enter the camera from lock screen, the animation is gone. It does come back after a reboot though. I am wondering if this happens to everyone or just me.

[Nexus 5 Q&A, Help & Troubleshooting] jamel_tza:
Like others have said, this is a confirmed bug. An easy workaround though is to swipe left on the lock screen as if you're going to access the camera then quickly swiping right before it goes into the camera app. In other words, swipe left then right.

If it doesn't work for you after you try it, let me know and I'll try to be more specific.

So bear with me.

Im on 02 contract.

I could install new rom. Openup the extended rom. Delete all the files I dont want (leaving the o2 ones).

Hard reset again (I have only done this about 100 times since last week).

I would then have the new rom with only the o2 stuff in extended rom.

Can the extended rom be used for anything else ??
[JASJAR, XDA Exec, MDA Pro Software Upgrading] JRH:
What I did was apply the new rom, then hard reset and allowed the new imate rom to run its customisaton. That prompts you to select your phone company and installs the default cabs you will need. It also installs skype and nackgammon but you can remove these afterwards via add/remove progs in settings.

Search the topics here for how to unlock the ext rom, then you can back it up to your pc and then delete it. I personally install apps such as pocket weather and tomtom to the ext rom.

Hope this helps...
[JASJAR, XDA Exec, MDA Pro Software Upgrading] Anton.Valleyman:
Even better...

I applied the new ROM, reset afterwards and then before it was able to apply the customisations I soft reset. This bypasses installing anything from the ext_rom and gives you a blank canvas. I then unlocked and unhid the ext_rom (there are tools in this forum for that), reset and removed ALL files in that partition.

I've since reinstalled only the ones I need from the files that WERE in ext_rom and have installed various apps such as Resco File Explorer, TCPMP etc into ext_rom. You cannot get back the memory from deleting the files, so it's good enough to use as a little bit of app space instead.

Cheers

[JASJAR, XDA Exec, MDA Pro Software Upgrading] CRJL:

Ant I'm new to this. how do I know which files I want.

[JASJAR, XDA Exec, MDA Pro Software Upgrading] Anton.Valleyman:
Props to the app owners...

Open the unlock first and run it. It will show "SUCCESS" twice, OK through and soft reset. Then run the unhide - which I think then requires another soft reset. Once back in, go to any file explorer program (even via your PC once connected) and you should see Extended_Rom as a folder on the root.

Cheers

I know I'm a dimwit but what files should I be leaving in the extended rom. I want to be able to use mms and txt and video calling. I'm on 02 so am guessing all the o2 ones for contract?

also if I want for example to put pocket weather into this to run from extended rom do I just put the cab file into the extended rom and away It goes or do I need to do something else.

thanks for your help
