DX(G) Kindle write/read question

VVhiskey · 03-26-2020, 11:13 PM

Well, I got a DX kindle, and I want to jailbreak it, but I have a problem already. And I'm really struggling to find a solution of that problem:

Every time I try to upload any .bin files or .pdf files to documents folder I'm getting read/write error on windows(watch this screenshot):

On linux I have different behaviour:
When I'm trying to

Code:

cp Update_kindle_2.5.8_B005.bin usbstick/

It shows up in the root of kindle, but after a few seconds device dissapears(without unmount) and then reappears with other identificator(e.g. device name was /dev/sdc and then it's reappears with /dev/sdd):

Code:

ls -lh usbstick 
total 24K
drwxr-xr-x 2 root root 4.0K Jan  1  1980  audible
drwxr-xr-x 2 root root 4.0K Jan  1  1980  documents
drwxr-xr-x 2 root root 4.0K Jan  1  1980  music
drwxr-xr-x 4 root root 4.0K Jan  1  1980  system
drwxr-xr-x 2 root root 4.0K Mar 23 01:13 'System Volume Information'
-rwxr-xr-x 1 root root   12 Mar 27 01:26  test.txt
-rwxr-xr-x 1 root root    0 Mar 23 01:23  Update_kindle_2.5.8_B005.bin

The size of file with kindle update package is becoming 0 and I really don't know what I should do with that! I tried to drop files with the same size and extension

Code:

fallocate -l 24M test.txt
cp test.txt usbstick

Code:

ls -lh usbstick 
total 49M
drwxr-xr-x 2 root root 4.0K Jan  1  1980  audible
drwxr-xr-x 2 root root 4.0K Jan  1  1980  documents
drwxr-xr-x 2 root root 4.0K Jan  1  1980  music
drwxr-xr-x 4 root root 4.0K Jan  1  1980  system
drwxr-xr-x 2 root root 4.0K Mar 23 01:13 'System Volume Information'
-rwxr-xr-x 1 root root  24M Mar 27 01:42  test.bin
-rwxr-xr-x 1 root root  24M Mar 27 01:37  test.txt
-rwxr-xr-x 1 root root    0 Mar 23 01:23  Update_kindle_2.5.8_B005.bin

Also I've got an image of that partition and mounted it. Then I dropped there Update package and it seems like problem is not with a filesystem.

Does Kindle software deletes Update package and files like that or there's another problem? Please, help me, beacuse I really don't know what to do. Tell me how to hack that tough thing. I want to use it ):

I'll appreciate any help. If you need more info, let me know.

Kindle version: Kindle 2.5.3
Serial Number: B005*

Also, sorry for bad English. It's not my main language

I solved my issue. The problem was related to my usb ports on PC. Despite the fact that I used them to connect my usb flashes without any error and perform some operations with my Kindle, using other PC's usb ports solved my problem.

I'm not sure how I need to mark this thread as solved, but I'll add [solved] tag to the name

UPD

Didn't find edit button, so, admin, if you read it, mark it as solved or close the thread(sorry, I'm new here, don't know thread closing rules)
