Kindle Keyboard 2 wont update

[raunak]

Hi Fellow Readers.

I have had a kindle Keyboard 2 B002A(sprint ) version for quiet a while now .

I am facing a few obstacles in updating the firmware for the same .
Currently I am at the version 2.0.4 which i believe is the base version it came with.

I am now outside the US and want to update the same to the latest version 2.5.8 so I can use the wireless while traveling .

have tried downloading the firmware to my pc , then connect the kindle over USB and transfer the .bin file into the kindle removable drive root folder.
But once i eject the kindle safely and go to Menu>Settings the Update Your Kindle option is greyed out and never accessible.

Also once I connect the kindle back to the PC , in the removable drive the .bin file has disappeared.

I request anyones help who may have successfully solved the same.

I did a bit of reading on the forums and realised that (correct me if I am wrong) I cannot go directly from 2.0.4 to 2.5.8 ? IS it so?

IS there any other intermediary firmware versions which I need to update to before 2.5.8 ?

There shouldn't be a problem, Amazon doesn't list any intermediary updates. Normally incremental updates are listed. Did you make sure to download the right update (WiFi vs. 3G)?

The B002 model **is not** the international model (its US only).

So be certain you are trying to install the correct model's update.

And I'm too lazy to actually check, but in addition to the model mismatch knc1 pointed out, your initial deduction does sound vaguely familiar, you might have to jump to 2.3.x before being able to move to 2.5.

EDIT: Yep.

2.3:
Minimum OTA 291330095
Target OTA 399380047

2.5.8:
Minimum OTA 399380047
Target OTA 555370010


Perfect match .

Just fudge the D/L link manually if FW 2.3 isn't listed anymore on Amazon's Kindle Software Update page.

That is positively stupid of Amazon. Why don't they detail and link the usual incremental upgrade procedure???

Wildly inaccurate upgrade page

FW 2.3 for devices with serial numbers beginning with B002

It no longer lists the older FW, so ....

https://s3.amazonaws.com/G7G_Firmwar...e_2.3_B002.bin

Install that one, and then ....

https://s3.amazonaws.com/G7G_Firmwar...2.5.8_B002.bin

Then install that one.
