Oh no not another bricked c240, please help. I've done quite a bit so far

OK. This is my first post on the Rockbox forum.
Before posting I had trawled through these forums and others to find and follow various solutions, but still no hope.
My sisters sansa c240 v1 stopped working. Only the menu  blue light comes on, No LCD.
It had rockbox installed and was working fine for about 6 months until now.

I went through the basic rock box unbricking steps in the wiki (using Unbuntu)
I tried the recovery mode step = no 16mb drive visible

Tried the erase procedure with e200tool and 240erase.bin and tried previous steps = no luck.
Note= its says in the wiki that it could take more than 45mins! mine took about 10-20 secs!
I tried it many times, same result.

Assuming Im in manufacturing mode
I then tried the recover pribootloader.rom via e200tool = it executes as described but does not go to recovery mode as written.
note= in the wiki it states "you need to hold down the record button on your player, otherwise you may miss going into recovery mode"
I only press+hold  the rec button just before I hit enter to execute the code. right or wrong?

I now believe I am in pre bootmode as in corrupt i2c. (lsusb command lists c240 as PortalPlayer)
The problem now = not many files for c200 series, specifically my c240. I cannot find a
a i2c bin file to repair in preboot mode. Can anyone upload a sansa c240 i2c file bin image please.
(I believe u can use the e200tool to do so, correct me If Im wrong).

So can someone now please help? I am a noob in linux, but have followed exactly and searched much before I resulted to posting. Its a cheap mp3 player to buy again  but would rather save what we have rather than throwing away.
Any mistakes in technical stuff please forgive.

Thank You

I don't immediately see anything wrong in what you did. The c240erase.bin on the wiki is definitely working (I just tested it again to make sure), so if it doesn't work for you your c240 is definitely in a weird state. Does c240erase show any errors on the c240's screen?

Do you have some idea of what caused this state (i.e. did it "just happen", or was it formatted, or...)?

Hello, I thought no one would help or had a clue.
Thank you for answering my call.

The c240 one day was working fine, and the next nothing.
Unlike others, never had a database problem, crash or other. just would not turn on except for the blue power led.

When I run RECOVER command with the c240erase.bin file it takes a mere 10-20 secs to complete.
No errors occur. memory is written, but I never get the next bit

"When the erase is complete, it will prompt you to press a button to shutdown. Do as you're told. You may need to release hold first."

Nothing promts on the linux terminal or the lcd. (right from the word go, the lcd is not even on, no blink, no flash or prompting, its like its dead. So i cannot from the players point of view know whats going in there as it cannot indicate to me.)

Yesterday I happed to come across a totally different rockbox page to the unbricking page I have been looking at. The Diagnosis Mode!

I tried that and suddenly it came alive. The screen then kept cycling:

erase sd nvp
erase sd media

this was going really fast at the start and then after about 1min it slowed down to a complete stop. I tried the pribootloader step, but nothing.

That diagnosis modes has not worked again, but I know its alive! alive I tell ya.

There must be something Im missing or have done wrong, or not timed correctly. Any clues?

So the e200tool says (amongst other things) "Execution started"?

This should appear on the c240's LCD

I'm not familiar with the diagnosis mode, sorry.

hi,

Yes after running c240erase.bin it states "Execution started".
It just sits there, i gave it a couple of minutes but nothing.
No LCD indication of any sort.

Do i have to wait for longer?

Im at a dead end.

Do you think it could be the i2c pre boot or am i jumping too far?

thanks  thus far
