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

[Alexdream]

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:

   ls /dev/sd*

   It should appear something like this:
   

   /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:

   sudo gdisk -l /dev/sdb

   you will get something like this:

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:

sudo -i

then type your password
now you must be under root access.

8. type the following dd command:

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

Nice job. This is what would be needed to be done.

dd  if=/home/alexdream/Desktop/aboot.img of=/dev/sdb#

might not be sdb6 on all variants

Also link a donation link instead of your email address, there is no way to control internet spam crawlers

I can not do it because when you use VM does not recognize me more than two devices, when I try to flash it , tells me that the file does not exist in the specified path and indeed what I have on the desktop

 

[tommy856]

any help with this error ... Problem opening / dev / sdb for reading! Error is 123 ... after putting the command ..sudo gdisk -l / dev / sdb

 

[sammyz]

Oh, I wouldn't use a VM. Try a live boot from a USB drive.

you must have installed in windows qshusb_dload drivers.

Which VM machine did you use? Some don't even support plug n play virtualization.

I use VMware Workstation 10.0.1 and everything was good. Virtualbox didn't work for me. I would recommend that use use live CD

Yea, live DVD/USB is less of a pain

you had errors when connecting the phone to linux?

[tommy856]

you must have installed in windows qshusb_dload drivers.

where I download the drivers?

 

[fearblade66]

whenever i run linux on livecd on my computer and plug in my phone it gives me volume 38 error and when i enter ls /dev/sd* i get sdd1 sdd2 sdd34 etc and i checked if it was the phone only happens when the phone is plugged in

Here is the tutorial to create a booteable USB Stick on windows, you must have a USB stick with at least 2GB of free space. To make a DVD boot disc just download the ISO file and burn.

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

Wait so when I download VM workstation does it come with Linux operating system or do I have to download a separate ISO file for Linux. What do I do next?!

You have to download a separate ISO file for linux like Ubuntu.. I suggest to you that use a LIVE CD to avoid to Ubuntu not recognize the phone..

Ok! Can I used my Micro SD card insert it into the USB SD card reader as my " USB memory stick" if so then I will definitely do it without a virtual machine.
