Very bad for you, so tablets with 121208 serial number have to be considered 3rd batch, w/different hardware and different bootloader.

Also notice that Root procedures doesn't seem to work on these batch.

Here's a post from F&l Superstore with few more info on this : http://www.slatedroi...post__p__470464

Fuser-invent will devellop more on this, he made an unbricking tutorial for the first batch...

Good luck Guys...

Once we get the 1208 firmware, we should be able to pull the bootloader and create a auto-flashable SD card. But if you hard bricked then you might have to experiment with the AML Flash tool as well. I've gotten a lot of reports that the AML flash tool got people out of M3 and M6 mode (I don't know the difference) and then there were able to use ADB or the SD card method but I've also got some reports from people who can't get the AML Flash tool working for them.

I happend to have a second tablet from the same batch with cyanogenmod installed, so i can't get the entire stock firmware, but here is a nanddump of bootloader and recovery.
So if someone is better at extracting the correct files from these than I am or helping out with some pointers, any help would be greatly appreciated. I did create u-boot-orig.bin by just removing the trailing zeros on the bootloader dump, but didn't have any bigger luck booting anything in AML flash, if something else is needed just tell me :D
Also, I tried reading out usb_spl.bin at 0xd9000000 with update.exe but I don't know the length.

Contact tigger-gg and she can talk you through getting everything we need. We also need some things for a batch 3 comp zip for the Crystal Clear ROM, so that would be super helpful.

All you can do is wait for a solution unless you troubleshoot it yourself. We're trying to get someone to make a nandroid backup and send it to us but no one has responded yet.

fuser, I ordred another unit from where I got the 121208 thats bricked, hopefully its batch is the same. If I google nandroid backup, might I find how to do a backup for you?

Tigger-gg has an idea. I guess what you would need to do is extract the CWM (Clockwork Recovery) files to your external SD card, boot into CWM, make a nandroid backup, boot up the tablet, copy the nandroid backup to your computer, upload it somewhere and post a link to the file.

Hi there, I bought two Crystals, one for each of my sons and these arrived today.

Having managed to get CM10 working on my Fire ... I was unfortunately feeling way too clever and tried to do the same on one of my son's Crystals ... which is now bricked :-(

I am wondering (and please bear with me - while I am very computer literate, I am very new to this ...) if it is possible to do a backup from the working one and get it working on the bricked one?
Also ... can I get information from the going one that would be of use to anyone here?

The serial numbers on the two units are 20 numbers different so I would guess that they are both from that 3rd batch ...
Best give me really good instructions given what I have already managed to achieve today! :D

Hi

GREAT TUTORIAL BTW very helpful :)

I have few ainol mars that are bricked....the only +ve is when i prepare a recovery card with usbit (USB IMAGE TOOL) the mars actually start flashing with that TF card inserted and power button pressed.
msg on flashing screen is

"upgrade step1!Do not Power off!"

this continues till battery dies (i guess)

I think it is the file structure and or commands in the "aml_autoscript" and the "factory_update_param.aml" i tried to change "factory_update_param.aml" with the commands in order of

--wipe_data
--wipe_cache
--wipe_media
--update_package=/sdcard/*****.zip


no luck as yet

Please help

What firmware are you trying to flash on your Mars? I took a peak over in your subforum and it doesn't look like there is any official firmware or recovery images posted there.
