How to finish the mp4 rescue ?
 

Hi,
I have a problem with my mp4, bought on eBay, like everybody here ^^.
It's the same like this one
http://www.mympxplayer.org/2-rockchi...ew-vt4410.html
It stayed on the loading screen and my PC didn't recognize it.
So I followed the Dead player recovery guide
http://www.mympxplayer.org/dead-play...ide-vt567.html

I managed to enable the ADFU mode and I installed this firmware http://www.mympxplayer.org/full-firm...515-df766.html because my chip is an ACU 7515
Miracle the mp4 appeared in the Explorer. I saved my songs ans I formated with MP3 Utilities 4.05.
Finally my mp4 is almost rescued. But the screen is now black and it doesn't want to started. According to the guide, i have to put a backup dump.bin (that's i don't have) and I don't know whose firmware I had to install. So can you help me please ?

I apologize for my bad English but I am French ^^.

If your player is like the one in this picture

then your player is Rockchip and you should follow this guide to recover it:-

did you check the chip inside your player?
is it really a ACU7515 or is it a Rockchip?

I also thought it was a Rockship, it's exactly like the one on the picture, however the chip which is behind the LCD screen is an ACU 7515 (69119EA 59S). So I'm lost :s.

Plus I read the Rockship guide but I don't have ConsumerUpdate soft and I'm clueless about my firmware if it isn't an ACU.

Here is a picture of the inside of my player

and here a picture of the chip http://img156.imageshack.us/img156/5884/pict0023we0.jpg

Thats not a Rockchip for sure, it's just using the same case.
You need to get the number on the PCB then look for a firmware on http://en.s1mp3.net

check out the useful info here too:-

On the PCB, I can read B0-050 **2007*02*18VER:C** on one face and B0-050 **2007*02*18VER:B** on the other face. Is it the right number because i didn't found it on s1mp3 ?

It's probably B0-150 try typing B0-150 into the http://en.s1mp3.net search engine

There are two files
LG_LZY_B0-15005_TFT70023_7515_V9.1.52.rar
LG_LZY_B0-15005_TFT70023_7515_V9.1.52_��������������_2007103 1(���޸�)����.rar

You may not know whose file I have to chose. I fear that I have to start it again :/
By the way, is it right what I've done untill now ?

Hi, I have tried différents firmware but they don't work
I have this error
"Read or write device information failed!Please exit the program and check if device is connecting"

When I renamed them "dump", I have this other error
"Invalid firmware upgrade file"

I will finish to think that there are no way to recover my player, all the more that there aren't any signs of life.

You will need to extract the .rar archives by using a program such as WinRar- google free rar extractor.

Once it has been extracted there will be the firmware files (.bin)- rename it so it is like this:

LG_LZY_B0-15005_TFT70023_7515_V9.1.52.bin

I had understood that i had to extract with Winrar.
The extracted file is a .fw file. I renamed it but I have still the error message "Invalid firmware upgrade file"
