I can't stress this enough, if you lose power while the eMMC is doing one of its read/erase/re-program cycles internally - the device will self-destruct.
- The flash memory as used on the Kindle requires a special set of options for its format.
The Windows formatter does not support those options, so don't use it. You will only make your problems worse.
- The storage area of a flash memory is not organized the same as that of a spinning rust storage device.
There is no relationship between the erase block location and the storage block order.
The relationship changes with every "write" (flash devices do not support a "write" operation - their internal micro-controller is faking it).
- The boot-up procedure of the Kindle will detect if the USB storage area is formatted, and if not, format it (with the proper options).
Use this feature, you have two choices:
- Select 'format USB storage' (or whatever similar menu entry you have) from the diags menu.
Keep it on external power and repeat until no errors exist (the eMMC's internal micro-controller will deal with blocks that fail ecc checks).
You have to repeat this because you only have access to a limited number of erase blocks and the entire set of internal erase blocks have to be cycled.
Did I mention? Keep it on external power ALL OF THE TIME.
- Use special Window's tools to access the raw storage area of USB storage (a very poor choice) or run a Linux LiveCD on your PC so that you can corrupt the USB storage area format and then let the device re-boot (and re-format the area).
Directions for forcing a USB storage re-build can be found in the original de-bricking threads.
- Keep the Kindle on external power!
You will probably find that all of this is a waste of time.
Most likely, you now have a used touch screen for sale.  |
Thank you for the info Knc1
much appreciated.
prior to 2 weeks ago I had zero knowledge and took a while to get used to the terminologies and tools being stated and mentioned in the forums...
i used checkflash 1.16 to check. I guess that may not be the best option or tool.
I am not very familiar with ssd and flash drive's.
I will follow through your advise and re-read through that particular thread.
while the battery gets charged.
I do have a linux desktop, will attempt recovery etc via that later on.
some extra info:
With the amount of time spent thus far it is probably wise to just swap the screen haha.
I am actually attempting an upcycling project as such I managed to secure a couple of K5's on the cheap (total < 20USD)
3 are plain dead (screen and hardware is somewhat kaput) but the batteries are healthy
1 has a faulty screen
1 has faulty Hardware and bloated Battery (this k5 that I am trying to fix*)
-*Battery has already been swapped with a known healthy one.
also
What do you mean by

Do you mean I corrupt the area on purpose?
once again thank you for your help thus far.
And yes I will keep it on External power!
