SX66: upgrade, then battery ran out and unit won't power up

[eleveneleven]

Hey all,

I've had an upgraded SX66 (1.4 cooked WM2003) for a few months now. Working fine, carrying it around with me and using it all the time.

The other week I left it upstairs without charging it - now it won't power up, sync etc. I had a spare battery for testing, the same problem happens. It does however, have the red 'charging' light on the corner of the device for about 20 - 30 minutes. If I pull it out, no go - but I can recradle & the light turns back on. Anyone experience this? Anyone have a workaround to resetting, reflashing, etc?

Since it went 'dead' here's a few of the things I've tried.

* Hard reset
* Charging 2nd battery
* upgrade with 'real' factory siemens firmware - since it can't sync it errors out (101)
* upgrade with maupgradeut_noid.exe util. With regular firmware, it claims to connect giving a here's what roms are on here's what we're installing screen. All lines empty. With the cooked roms it starts something up, says it's finished - but it still doesn't power up.

Any help appreciated, driving me crazy.

Have you tried entering bootloader mode?

Try Power + Record and reset

I have the same problem. Left mine out over night, battery went dead now it won't turn on. Red light on the front when plugged in. Any ideas?

seriously... same thing happened to me...

force into bootloader mode by

(soft reset button + Power + voice record button)

It worked for me...
