RockBoxed Clip+ completely bricked

(1/1)

pbrainii:
1. I dropped the player, the power button came out of place.
2. I opened the player and reset the power button and applied some glue, it worked for a few days, after that could only use when turned on by plugging usb cable to power source.
3. The screen started fading and was completely gone after a week.
4. I could still use the player (with the voice file) for a few weeks with no problem.
5. While listeing yesterday, it died, I tried recharging, nothing, hard resetting, plugging to usb on pc, plugging to usb charger, nothing. I also opened it up again, cables seem attached.

When plugged on a PC, it either doesn't see it at all as plugged in, or it says device unrecognised..

HELP!!!

saratoga:
I don't think you're going to be able to fix that.

pbrainii:
Well, today I plugged it in on the pc and it came back alive, was recognised, could see all the files and after charging for a few hours it was playing normally.

Strange...

mcc01:
Hi,

I think it is not that strange...

Pure theory:
A certain hickup in the hardware screwed up the CPU (CPU internal hang up).
The battery was already below the lowest power to start the device but
delivers enough voltage to keep the (wrongly populated) internal registers
of the CPU alive: The confused state of the CPU remains and locks itself
off from the "real and healthy world".

After a night of doing nothing other than draining the battery a little more,
the voltage falls below the point the CPU keep their confused registers.
Everything goes back to zero, init, start or whatever.

Attaching power in the mornig was like a cup of fresh coffee for that little
device because the CPU now was able to start right from a blank sheet.

Voila!

I think some of the "totally bricked devices" could be taken back to
live to desolder the battery for a night or so to discharge anything
and to give the CPU a really really fresh reset without remembrance
of its confused past.

WARNING!
Pure theory extracted from the experience with other embedded devices.
I do not even own a Sansa player (but hope to do it soon... :)
WARNING!

Fingers crossed...

Best regards,
mcc

pbrainii:
well, the player still works fine.
I've had a sansa clip generation 1, act similarly (it wouldn't light up at all even when plugged), after several days on the charger, it came back alive, eventually died when it was about 5 years old...
