Ipaq 3870 hard Reset doesn't work.

Ipaq 3870 hard Reset doesn't work.

hard reset doesn't work. Holding keys 1 and 4 while resetting for 5,10,30 seconds
produces a soft reset, NOT
the desired hard reset. I can remove the battery, but that little connector won't
do it many times before it breaks.

Google finds others with this problems, but no solutions.

I do a lot of experimenting with this system. Factory reset would save
me some trouble. I just wasted a day trying to make the serial port work.
Pulling the battery fixed it.

Also, that's the way you put it into "shipping mode"
so the battery doesn't discharge and murder itself between projects.

The rom version is 2.15.12 ENG.
I think that's the stock version???


My 3850 hard resets just fine. I'm a little fuzzy, but when I replaced the 3850
battery, it refused to do anything until I stuck it in the charging cradle. That's
a symptom of being in hard reset mode. Reconnecting the 3870 battery
makes it power up by itself
.
Is there ANY way to hard/factory reset the 3870 without removing the battery?
Or a way to force it into battery disconnect/shipping/ mode.
Thanks, mike

There's third party software you can use that includes a way to perform a hard reset by selecting an option off a menu.

SKTools includes such an option and I think I remember seeing an option in PHM Task Manager.

Still can't do battery disconnect mode on ipaq 3870

Thanks, PHM solves the hard reset problem, but the PDA still restarts
after running it.

The ipaq 3850 goes into battery disconnect mode on left-right-reset hard reset.
PHM does the full factory reset, but does not go into battery disconnect mode.

Battery disconnect lets you stick it in the drawer for extended periods without permanent
damage to the battery. I've got 22 pda's...I've killed more lithium batteries by letting them
run down than by use.

The 3870 just restarts after PHM hard reset.
The left-right-reset with the buttons results in a soft reset/restart.
Software issues surrounding hard reset solved by PHM.

Still need way to get into battery disconnect mode on the ipaq 3870.

Ideas?

Thanks, mike
