Flash - File Check Error, Bricked? Help!

[aw079]

Hi guys,

I have searched everywhere to no avail, so I assuming that this will be a new question.

Device: MK809 [T002] with Hynix flash, MediaTek MT5931 WiFi
Netxeon MK806 v2.0 written on PCB

I have previously flashed Finless Bob and stock ROM, no problem and have used it successfully, then suddenly today after attempting to re-flash, my problems starts.

When flashing, after data has completed downloading to Nand, device always fails check [data verification] at approx same place [roughly around 180 MB]. Any ideas on what can be causing this?

The only thing I can think of [but hoping that it is not] is that the flash memory has developed a fault in that area, [just like a HDD having a bad sector] but this is just a guess, as I am not even sure if such a thing can indeed happen, it could be all or nothing on flash, no bad sectors?!

If need be, is there a way or a line I can change in the RkbatchTool to disable/bypass the checks?

I have tried flashing both another custom ROM, and the stock ROM without any luck, same result, after download, checks fail.

Hi,

Sorry for you pal,

It happened to me several times, and it is always a pain.
It can be caused by several things.
Some causes are easy to fix, some are not fixable.
So, hope it will be easy

* you use a usb3 port : it can cause some problems. If you have a usb2 port, try it instead
* you use a usb hub : don't do it. Plug your device directly to the pc
* try on another computer, it may work better
* the hardware you have doesn't support the bootloader included in the rom kit.
Let me explain that one :
- I have an Arnova 10G2 tablet sold in Europe
- The rom maker (Bob) has an Arnova 10G2 sold in the US
- The roms he releases run without a problem for me unless I flash the provided bootloader too.
- So the same bootloader can work on some devices and not on others.
- If it is the problem you face, try to flash the original firmware, then try to flash the custom firmware without the bootloader
* last solution : you have a faulty NAND chip. And all you can do is return your product for an exchange

Notice : there may be other cases I don't know. I only speak about the problem I faced or heard about.

Edit : maybe this thread can help too : http://www.freaktab.com/showthread.p...D-on-the-MK808

Mine flashes fine and it completes that stage, its just the verification process where the flashed data does not match the image file. I tried both MK809II stock FW and Finless Bob 1.7 Sunval clone as they both use the same Wifi chip and previously worked perfectly okay.
I think the nand chip is gone, maybe I flashed it too much, a total of 8 times [worked perfectly], then another 20 times, trying to get it to work.

Brought off **** from China, so it was cheap at £28.50, which makes it unfeasible to send back. Besides I think the warranty may also be voided due to the fact that it was opened and flashed repeatedly.

Gotta bite the bullet now, and shop for another one.

I have been looking at the G-Box M6 with AM logic MX Dual Core processor, apparently it suppose to play XBMC much better than the RK3066 chips, so might give that a go.
