Root (GUIDE) Unbrick LG L70 No Download Mode No recovery mode, No Fastboot

I tried live CD and my 2gb SD card but neither worked so I decided to try VM workstation 11 and I got ubuntu (32bit) desktop 14.04 to install and it works. So how do I attempt to install qhsusb_dload in windows and what do I do with the aboot file?! Thanks for the guide by the way. Hopefully I can unbrick my MS323
 
ayudenme yo segui la guia al pie de la letra pero aun sigue sin encender. lo copie todo exitosamente y nada mi telefono sigue muerto por favor ayudenme
 
I'm having the same problem gentlemen. I've got the same file system and the phone loads under the qsub whatever drivers there. I'm running unbuntu 14.10 distro on a 2 Gib thumb drive. When i plug my phone ine the usb port the phone starts cycling through a black screen with 3 levels of backlight acsending. (bootloop??). I really want to get this phone back up and running. I had two of these phones and i rooted the other one unlocked the bootloader and have CWM recovery istalled and scripted to run dumbass backups before i do anything else. I'm thinking I'm missing a driver and also looking into go=mptfs. I would appreciate any input. thanks for your time and effort in advance
 
Never mine that,this guide help my phone, but it stay stuck on boot (LG logo) and i have fastboot but what should i do next?i tried LG Laf Recovery Multitool v1.2 to restore recovery.img but how to go to recovery mode? i cant restore download mode. i see the tut on unlock ms323 but it when trying to restore download mode i have to put back my laf.img (partition) in sd it say"adb push laf.img /sdcard/".when doing that it say cant detect device?HELP please,im so close to fully reviving my phone.

(UPDATE)
Now the phone can boot normally but take about one minute to fully boot on.then i use "LG Laf Recovery Multitool v1.2" to to restore my back up of my laf.img(in phone)and to restore download mode,then noticing that my my mobile data signal bar had an red x indicating of my service is disabled.my SIM card was still in the phone.I didn't went in the phone and do anything.then on the LG recovery multitool, i use the option to boot into recovery knowing i have CWM flash in the phone,then i choose the option to "wipe data/factory reset"and"wipe cache partition",hopping that will fix the problem of service being disabled.when finishing setting up the phone i still notice that the service is still disable with no bars but a red x next to it.When googling my problem, the perhaps the only way to fix this problem is to using something called Octoplus box which require a card or a box??In other information i notice in my status in option "phone #","IMEI","IMEI SV",and "ICCID" had the word null. how should i fix the problem without this octoplus.

Hi all, I just want to said Thank you to Partarger.info member of xda forum for your guide for LG G2 that I used to fix my phone after that I followed this guide to put in my phone CWM recovery and no one was able to help me or tell me something about this problem.

The problem to this situation was you wrote over the aboot which is needed for booting the phone.

Symptoms:
  • No download mode
  • No Recovery Mode
  • No fastboot
  • Just Blacks creen
  • When you connect the phone to pc you can see two folders: one is "Image" and the other one "verinfo"
  • LG detected as qhsusb_bulk in device manager
Requirements:
  • A little Knowledge of linux
  • You will need to use Linux, you can use Ubuntu or another that you want. You can use a virtual machine, live cd or a bootable usb stick.
  • Download stock aboot of the phone from here.
Step by step
  1. Boot into Linux and plug your L70 to the computer. Note: if you have linux in a virtual machine you must have installed in windows qshusb_dload drivers
  2. Put the downloaded file decompressed in the desktop
  3. Open terminal in Linux then type:
    Code: 
    ls /dev/sd*
    It should appear something like this:
    Code: 
    /dev/sda /dev/sda1 /dev/sda2 /dev/sda5
/dev/sdb1 /dev/sdb2 /dev/sdb3 /dev/sdb4
/dev/sdb5 .......... /dev/sdb34
  4. In this case my device is detected under sdb. you may have it under sdc. look for the biggest number, in my case /dev/sdb34 so it is sdb.
  5. In terminal type:
    Code: 
    sudo gdisk -l /dev/sdb
    you will get something like this:
Code:

6. We are only interested where is located aboot partition, in my case is located in sdb6. Be carefull because in your case it may be located in another partition. not be confused with boot partition or abootb.

we will use dd commands to push aboot.img inside the right partition.
7. in terminal type:
Code: 
sudo -i
then type your password
now you must be under root access.

8. type the following dd command:
Code: 
dd  if=/home/alexdream/Desktop/aboot.img of=/dev/sdb6
Note: alexdream is the name of the user in linux, you have to replace for you own user. Replace this path by the appropriate path to your file

Once you finish just reboot your phone, if everything was good your l70 now can boot normally and you can go to the download mode too.

You can follow this guide to replace recovery is you want, just remember not replace stock recovery to the recovery partition.

This guide is for LG L70 MS323, other variant can work but you have to search stock aboot file.

DISCLAIMER: I am not responsible for anything that may happen doing this. Make sure to make it right!

if you fixed your phone can collaborate to pay me a beer :D

Friend, my situation is similar to yours. "I tried LG Laf Recovery v1.2 multitool to restore LAF.img and say :NOT FOUND , ZERO Laf say:Not Found.Other options work fine,but restore laf not work
AD Shell say : Device not found .How to put the boot image and the LAF on the phone if the message 'Not Found' in ADB Shell and LAF Tool?????

In recovery mode the error is:
"Invalid Boot Image Header "on screen

In Download Mode almost make update via LG Mobile Tool suport but the error is this:

system:system_3653632.bin(524288)
BackupGPT:BackupGPT_7633920.bin(524288)
Cross D/L Fail, phone : LGMS323, binary : LG-D325
Download exception Error
¡Ú¡Ú ERROR REASON : LAF_ERROR_INVALID_INPUT_FILE

Please can someone give some suggestion or solution. Repeated several commands and various tools and has no effect. Thank You all .

Hi!

Just wanted to share my experience, it might be helpful for someone ☺


So, after I messed up (soft bricked) my phone, by wrongly mounting/unmounting during repartitioning the system - this is what I've got:
Userdata and cache is gone and the rpmb (whatever that is?) is wrong size?
I can reach adb (twrp) and fastboot (download mode) and I've already tried all possible methods to restore laf, aboot, boot and different recoverys, even the stock recovery? Restores alright, but I can't get to stock download mode with button combo (a ms323 thing I think).
I believe my last resort would be to learn (if it's even possible) how to create/repartition/resize partitions in adb? Or if it's possible to flash userdata.img and cache.img (if someone can upload it)? But I assume I have to create those partitions first?


LG optimus l70 ms323, messed up partitions:

mmcblk0:

p31 1587200 system
p32 # [295mb] cache
p33 # [1.48gb] userdata
p34 20463 grow
rpmb 4096 [512kb] xx

# = non existing partition

[ ] = original size

???



Solved ☺

Couldn't have done this without all the brilliant help from: @Kamil Mazik, @DevMyAndroid, @Shahell Salvin Deo and @crutchcorn ☺

Thank you so much guys!!!

Even before this problem, I never solved the restoring of laf (download mode), but thanks to Kamil Mazik's recommendation to flash an older twrp:

https://drive.google.com/file/d/0ByEz7OmJjgdcdkFSRUFMWG9GNEE/view?usp=sharing

it worked ☺ Well the actual flashing of the laf.img worked before, but now the download mode works ☺

I'm not sure if it matters, but crutchcorn shared the proper ms323 laf.img if needed:

laf.img (ms323)
https://mega.co.nz/#!5h93lRyJ!3T_woM7e2W8xB8jNA4MPsSaOfEPe1cNhIzClv2aCHH4

And then the flashing of ms32310c works at last:

LG flash tool
http://androidforums.com/threads/unbrick-twogbsds-simple-unbrick-guide.864922

And please, straight after unlocking bootloader, restore laf, so you'll keep download mode - it makes everything so much easier (in case of brick)

And after rooting and unlocking bootloader (again, puh) the repartition worked flawlessly with PhilZ recovery thanks to Shahell Salvin Deo's post:

http://androidforums.com/index.php?posts/6917893

Have in mind that if you want to restore a ROM backup after internal repartition, make sure your backed up system aren't bigger than the repartition makes it and also, I think it's important that the ROM backup was made with the same recovery that you will restore it with.
