@tigger-gg,thanx so much for the feedback.Is that same as the sd card method as posted by fuser for soft brick?
In the stock 0928FW,there are fewer files (3)inside the zip as compared to the elf image (6 files),will that affect anything?
Kindly clarify for me how to go about it so that i don't hard-brick it again hence go back to the same problem i had before (i don't want to go thru that AML flash thing again).i will appreciate detailed feedback on this step

- download the elf2_0527.img
- download the stock FW 0928
- unpack the stock FW 0928
- dont use an sdcard which is larger the 2GB!
You can use sizes of 500MB, 1GB or 2GB.
- follow fusers method to create the sdcard with USB Image Tool
- if the sdcard is succesfully created open it in some file explorer

- delete the following files from sdcard:

-- factory_update_param.aml
-- WhateverTheNameIs <img src='http://www.slatedroid.com/public/style_emoticons/<#EMO_DIR#>/wink.gif' class='bbc_emoticon' alt=';)' />.zip
-- u-boot.bin
-- uImage
-- uImage_recovery

- let aml_autoscript on the sdcard

- copy the following files from the unpacked stock FW 0928 on the sdcard:

-- factory_update_param.aml
-- g06ref-ota-eng.grady.wang.zip
-- u-boot.bin
-- uImage
-- uImage_recovery

Turn your crystal off. Put the sdcard in the tablet.
Push "Vol -" and "Power" together and hold it for a long time 8)
At first you will see the green Ainol Android with chinese fonts, then the screen goes black, then green Ainol Android with chinese fonts will displayed again. One moment later you will see another green android with the spinning thing in his belly and an progressbar.
Now you can release the buttons :pardon:
If the process is finished the screen turn off.
Remove the sdcard, turn your crystal on and pray ;)

EDIT: Sorry, you´re right that in stock 0928 there are only 3 files. Here are the other:
Attached File  aml_autoscript.txt   150bytes   56 downloads
Attached File  uImage.zip   3.45MB   90 downloads
Remove on both files the ".txt" and copy these files to your sdcard too.

1.- crystal open and connect by USB TO PC:

2.- Made a bridge with one needle in pin 5 and 6 and push power ON ... AND OK recognized like M6 Chip
(after install worldcupdriver)
for testing I unplugged usb from PC and put another time and OK .. recognized
In this point I turnoff the tablet ...

From this moment if i turnon tablet plug with USB to PC NO RECOGNIZED. I supose because i dont have the disolder wire red an solder wire red.

I must repeat every time with the crystal OPEN the point 1-2 with needle in pin 5 and 6 then ok again.

My doubte is the order :

with tablet off disolder wire red ?
bridge with the needle in pin 5 and 6 and push power ON ( its the step 1 ) then recognized PC
TURNOFF tablet and resolder wire red ?

OR

with tablet off disolder wire red ?
with tablet off resolder wire red ?
bridge with the needle in pin 5 and 6 and push power ON
and after turnoff

Sorry but i am very newbie in this aspects ....

Thanks again

Resume : I need to can have a Hardbrick without bridge with the needle in pin 5 and 6 and push power ON every time
Its like batter its blocked or something ...


Sorry that I ask again :rolleyes:
Did you find a permanently solution?
Next question:
You wrote that your tablet is recognized as M3/6 by your PC. Why you turned it off? Why you dont follow at this point the instructions for AML Burn Tool?

For the people who are unable to get their device recognized as M3/M6 on the computer, such as albertsbd, there is a hardware hack to short out the system and use the battery to trigger and on/off switch sort of thing. Here is the thread I ran across.

Thanks to tigger-gg this file might be useful as well.

If we have 2 of these chips (like in batch 2 and 3) which should we choose :wacko: ?

tigger-gg, I'm not sure which chip to jump but there is no harm in trying both and seeing which one works, it won't do any damage.

To everyone else, when I get a chance I will do another update to the main post with tigger-gg's additions and I will upload all the rescue images as .zip packages instead, so you can just extract the zip and place it on the SD card you created with the ELF2 image. I bought a 512MB SD card which should be here next week, they are damn expensive for being so small, maybe they don't make them anymore. Anyway, I'm thinking maybe if I create the images on that card with device mode it might work. If you create them in device mode on a 2GB card, the images end up being 2GB which is way to big to be uploading and downloading.

I dont know if you have readed my post.
Also for me AML stopped at 8%. I ignored this error.
If you want you can try my instruction from my last post.

Start AML, let it stop at 8%, then unplug USB from your crystal, insert the sdcard and follow the instructions in my last post.

I dont know why some people say we have to desolder the red wire and some people say no desolder.
I dont know which is the right way.
I have here 3 totaly dead crystals and I have tried many times to shorten pin 5 and 6. But the PC does not recognize one of them.
Did you pushed only the power button or power and Vol-?

Ok, I tried again with one of these crystals. This crystal is still alive, the battery is broken. I tested with another working battery and with this battery it booted.

I'm on my fifth Crystal having purchased them for family and friends. I just received another from F & L Superstore since I live in California and they are an advertiser on this site. I decided to try our Crystal Clear, however the re-boot resulted in a hard brick. I'm pretty sure this is batch 3 as this is a new purchase. I'm trying to go through these threads, but do I really need to open the Crystal and de-solder the red battery wire? Is there another method of force booting without opening the case?

I really like a step-by-step approach to fixing the brick. Yes, and many thanks ahead of time if you can post this. On the other hand, pointing to the right threads will be as good.

Before I started AmlogicBurning Tool I have edited in the AmlogicBurning Tool folder the file configure.ini. I changed lanuage=en to lanuage=de (my language that is installed on my PC:

[General]
lanuage=de

[Erase]
enable=true
erasecmd="nand rom_protect off;nand scrub 0;poweroff"


I started AmlogicBurning Tool as administrator.
...


So no need for Chinese or English Windows version then?

Here is the second Ainol Mars recovery test. If it doesn't work the first time, try creating the SD card with the Tornado .img and then copying these files over. Let me know how it goes and I'll try again if it doesn't work at all.


One more, hope it's not already mentioned/tested.
