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:

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

well I do but I think the problem starts when I connect l70 in ubuntu. begins to apparate windows error saying assemble. is normal that to happen? after putting the second command starts the error, any suggestions?
excuse the English but I'm Mexican.

you had errors when connecting the phone to linux?
or is it normal?

I suggest to both that using a Ubuntu live CD to avoid this kind of errors or problems.
