Thank you so much for your mentioning regarding mechanical connection to the flash memory daughterboard
When I got that bluewhell of death, I prepared for long manipulations with flashing device in manufacturing mode, but luckily that was enough to gentle press the piece of foam above the battery. After that device booted normally. :smileyvery-happy:
The story was: my device had hang up after I accidentaly pressed record button while listening to music. The usual Recording screen appeared, but with no stop or pause items. Power button did not respond, neither one of others, so I had to remove back panel and remove the battery, after which bluewheel got in place, and Windows seen only Tango Media Platform instead of Sansa.
