Root D320n doesn't connect to computer

Hello,
I'm new here in the forum and asking for some help with a L70 (D320n).
After having installed some update my wife's L70 run into the Purple screen with the "DBI Error fatal" message, no hard reset, no Download possible.
I found the thread http://androidforums.com/threads/gu...oad-mode-no-recovery-mode-no-fastboot.893311/ to unbrick the cell by flasing a new aboot.img, which is provided in the thread. It uses a Linux computer which I preferred as I'm a Linux professional. Furthermore I found http://androidforums.com/threads/dump-all-variants-aboot-files-and-how-to-flash.918174/ doing the same on Windows and providing several aboot.img files.

The cell got connected as a device on my machine and I started to "dd" the aboot.img files from https://www.mediafire.com/folder/1or45xhf4uttm/Aboot-Dump#h3pw1qt06fuc3 (sources the "windows thread" mentioned above links to): But none of both changed anything. Then I "dd"-ed https://dl.dropboxusercontent.com/u/14171402/stock aboot LG L70 MS323.zip from the Linux Thread. This one did some changes, but only bad ones.

Current status is: Connecting Battery, pushing Power-Button leads to a "LG" sign, but Boot process never ends. Hard Reset can be chosen, but never ends, and so does Download mode.
The worst: I can't connect it to my computer any more.

I found some hints that a connection to the computer may be possible after shorten "testpoints". Is this correct? Could somebody tell me the position of the testpoints?
Any other ideas?

Regards,
Radlwadl
 
Yes, those two files in the D320n folder were the first ones I tried (see the first link in the 2nd paragraph in my post above). After flashing these nothing changed: The Cell booted into the Purple screen with the "DBI Error fatal" message.
Finally I tried the bootloader from here as this link is mentioned in a L70 thread, too. After flashing this bootloader the cell hasn't been recognized by my computer anymore. So currently there's no way to flash another bootloader as I can't connect computer and cell.
That's why I'm asking for some kind of "very hard" reset by shorten testpoints.

Regards,
Chris

Your phone malfunctions because you've flashed a bootloader that's designed for another variant of L70, that is Metro PCS MS323. I have never seen any test-points instruction for L70 and I've been a D320N user since it's release. There're some for LG G2 over the internet, maybe those might help.
 
Yes, I guessed having flashed a wrong bootloader.

I found this post here in adroidforums.com. It describes exactly my D320n's behavior and I hoped that there exists some "trick" to at least enable PC-connection.

Hi there,
I have a LG D320 device that one day just freezes up on boot (sits at LG logo forever).
I cannot enter download mode (Holding vol+ goes to loading screen and says to keep holding down until loaded... it never does)
The factory reset mode is accessible but I want to get the data from it first (Vol- on boot)

The device will only connect to a PC if I short the testpoint on the phones motherboard. The USB mode entered is QUALCOMM HS-USB QDLoader 9008 (after installation of the relevant Qualcomm bulk drivers).
Like I said, I only want to get the data off it and tried following instructions:
http://www.droidsavvy.com/unbrick-qualcomm-mobiles/
http://forum.xda-developers.com/showthread.php?t=2582142
But the partitions do not show up for copying!

Does anyone have any advice on how to go further?
I believe I need to use either QFIL (http://www.androidbrick.com/download/qpst-2-7-build-422-qfil/) or BoardDiag3.99 (like this instruction http://gsm-tips1.blogspot.com.au/2014/12/tutoriallg-g3-boot-repair-stuck-in.html). But I don't have the required files on hand (they ask for a partition.txt file, tot file etc...).



Like I said, I just want to get the data off the phone can anyone help?
I have gone through what I can but seem to be at wits end.
I can set this up on teamviewer if someone wants to log in remotely to try fix it.


I have posted a picture of the mobo, the CPU is an MSM8210 and eMMC is samsung kmk5x000vm-b314)

This question remain unanswered as well just because there's no known method for l70 test points. At least for now.. Maybe there's someone who tried to find them but surely it haven't been posted anywhere here.
 
I understood the quoted post in that way, that its poster (het1) was able to create a connection between his L70 and his PC by shorten the test points. Seems that I'm wrong and that I've to improve my English ;-)
Anyway - we decided to send the cell to LG. Perhaps they're able to repair that. We would pay some Euros for that as we don't want to trash it.

Any advice how to mark the thread? Or should I keep it open until we got response from LG?

You may leave the thread as it is :)
BTW, this is a "root" related topic, so you've chosen a wrong tab to post this thread.

@scary alien can you please help us again?
These are surely "root" related topics ;)
