If you phone Kindle CS they'll offer you a discount on a new Kindle.

Already did that, got 15% discount. My battle with this Kindle it`s not about money. I just don`t like to waste resources. I don`t want to throw mint device in trash bin. I will try to do what i can, if there will be nothing more i can do - so be it.

If he can get the serial number and such off the mmc, is it worth trying to flash main back?
At least part of the mmc is working, right?

Do those errors with cmd resp code and the IO error definitely mean the magic smoke has come out of the chip?

Yes, they do.
Note that the example above is the result of read commands, not of write commands.

Flash chips do not support "write" operations (the hardware and/or software is faking it).
All they can do is read, erase, merge new and old data, then re-program complete "erase block" sections.
They are actually an eeeprom (electrically erasable, electrically programmable, read only memory) behind an included micro-controller with built-in high voltage generator for the erasing.

They can sense (some types) of erase block failures, and do have spare erase blocks that they can substitute.
But they only have those in a limited supply.
When they run out of spares and good (programmable) erase blocks, their useful life is over with.

No, it did not smoke.
The battery ran out of charge during that internal sequence of operations that fake 'write' operations once too often.
The usual sort of failure is the micro-controller has recorded an erase block as 'erased' (while the erase sequencer was erasing it) and the high voltage (erase voltage) generator lost power before completing the erase sequence.

So now a non-erased, erase block is recorded in the list of erased blocks, when its turn comes to be used, it will not program (an eeeprom has to be erased (all 1's) before it can be programmed (0's written where required)).

The micro-controller in an eMMC is not sophisticated enough to recover from such a situation.
The micro-controller in SSD devices is considerably more sophisticated.
The micro-controller in a USB flash stick is considerably less sophisticated.
The specifics of the micro-controller and its programming are trade secrets of each manufacturer.

You can not flash anything to a flash memory that does not work.

Replace the flash memory chip that has failed.
We have (in the developer's sub-forum) a thread with directions.
Follow directions to flash the proper (for this purpose) u-boot to the new chip.
Directions in the same thread.
Follow directions to flash the proper diags kernel to the new chip.
Directions in the same thread.
Use the kernel's initramfs ("Recovery Mode") to flash the diags system to the new chip.
Directions in the same thread.
Use the 'Diags' system to flash the kernel and file system of the 'main' system to the new chip.
Directions in the same thread.

You are in the wrong forum for getting extensive repair directions, use the sub-forum (where the threads you will need already exist).

OR

List the device for sale as: "Not working, for parts only"
Sell it for the display and touch screen.

First thread not second thread.
Oh if a device is not working, it is no longer mint.
Good luck.

First is the replacement thread I had in mind.

The second may be of additional help, I haven't compared what information is available in both of them.
(The second one does not require an installed or working Diags system. It is from someone who used "erase all" on the device - which does what the label says.)

Paperwhite Gen 6 should be the 2013 model, I'm not sure where you are located for shipping, but I have been happy with this site where you can buy a replacement logic board.

https://www.powerbookmedic.com/Amazo...3-p-46083.html

So if the screen and everything else is good, you could just replace the logic board ( if you really want to buy the MMC chip and replace that, go for it, but this is a lot easier :-) )

The only one they have in stock is wifi-only with Special Offers though.

I will check this out. Thank You. I live in Eastern Europe, Riga, Latvia
Is it Plug & Play? Just replace logical board and we are ready to go?
Will I be able to do JB on this board? So i could get rid off Special Offers.

Keep a copy of all the device specific numbers.
You may want to transplant those to the motherboard you buy.
(The idme command can write them into the motherboard for you.)

That will also cover you in case the board you receive happens to be blacklisted.

And once you get it running again, jail break it before it can connect to the Internet and update.
Once jail broken, make a complete backup:
https://www.mobileread.com/forums/sh...d.php?t=289690
That backup routine is the only way you can get a proper version, matched pair, of diag kernel and diag filesystem for the device. *
Amazon does not include those in the full update image files.

Put those files in some safe (not on the kindle) place for the next time it breaks.

(*) And for all the people who have asked for it, and all the people who should have it, I find it hard to believe there has only been 16 downloads.

Yes, a bit ironic.
By mint i meant, that my Kindle doesn`t have a single scratch on it. I have treated it like a newborn infant for two years. But it seems that my Kindle eMMC doesn`t give a damn.

When i will get this thing rolling, there will be 17 downloads, that`s for sure.
Thank You.

Ah, so it is like a stored Corvette with blown engine. Looks cherry till you try to start it.
