How-To Recover your Bricked S9 using Tcctool

[WAI]

Hello, a User: joecool finally found the right value to unbrick his S9. other users who had bricked theirs followed and accepted to use this value and it was a success! we all would like to thank him for his work and help

NOTE: Tcctool should ONLY!!! be used if you..

-Can't seem to connect your S9 to a PC [S9 not being detected once connected]
-S9 appears to reboot [A repeated Loop while accepted to load the OS [Firmware]]
-Can't turn on S9
-All other things Failed [Tried turning on while Charging or trying to use the reset button, Etc.]

DOWNLOAD TCCTOOL

[Note for Windows Vista and Windows 7 users] i have found out that tcctool doesn't work and is unable to find the S9 while accepting to use Tcctool for Unbricking your S9. reboot PC and hit F8 before Vista or Win. 7 boot logo appears. There will be several options. Select [Disable driver signature enforcement] and that should allow you to use Tcctool. You'll have to do this step everytime if you want to use Tcctool though

I was following the other tcctool thread. At last someone found the right value and that's amazing that we dont have to send our s9s to cowon for unbricking. thanks to all people working a lot on this especially as i remember "who am i" "joeyg" "joecool".

[rvasquez6089]

I Try to check as often as possible to see if y'all figured out the memory code and you finally got it ! =D I freaking yelled when my cowon turned back on after 3 months of sleep. thanks to you guys =D

Take care

@Who Am I

I have the exact same situation with the Cowon X7. I have manage to go through almost all the steps (you can plug it in boot mode by pressing "M" (menu) when plugging it. But in the final steps, it is not detected. I suppose it is because Tcctool is not programmed for the X7. Do you have a clue as to what I could do ? (Tcctool did successfully upload the .bin file to the X7 but then it's not detected.)

Thanks

Thanks

so after the File Transfer through Tcctool X7 doesn't get detected by Windows? may i ask how the X7 got bricked? last thing i read was somebody transfered a few Files then they turned it off and couldn't turn it back on

[michael.amouyal]

I just transfered my files on it, and when starting again, it gets stuck in the "updating database" phase. There is apparently nothing I can do (I tried a lot of things). I just discovered that I could put it in USB boot mode by pressing M when connecting it.

Hi, I have a problem with the s9 8GB
I do everything according to your instructions, but after installing COWON_S9_FW.BIN player restarts and the computer does not see his ((Please help me
PS: please forgive my English the. I'm from Russia = D
Google translate))

[WAI]

are you completely sure you followed the steps correctly? does your S9 come on after the first step?

[Menny]

Yes, he included a little loaded and off. On your computer, it does not appear as a separate disk, but only T7901 usb-boot mode.
He stopped working after formatting with 64KB cluster ((
My hand curves)

[WAI]

idk, after the first step your S9 should be detected. could try another Computer

[Menny]

after 1 this after
-Open CMD and input cd C: \ tcctool then tcctool-d cowons9 COWON_S9_FW.BIN then press ENTER
or after
-Connect the S9 WHILE Holding the play / pause ??
tomorrow will try on another computer

[WAI]

the S9 should power on after this step: 'Open CMD and input cd C:\tcctool then tcctool-d cowons9 COWON_S9_FW.BIN then press ENTER'

[Menny]

This move I did already many times, nothing happens (
