Boot Loop with Non-Removable Battery

**Noxzoul** · 05-22-2012, 05:33 AM

I know from time to time on my old EVO I will get a in a boot loop messing with ROMs and would pull the battery. Does the new EVO have a button combination to force a reboot?

Thanks.

if its like the OG EVO then you hit Vol up, Vol down and Power at same time. i would assume its the same.

Yeah it does. I read somewhere (can't find the link now) that it's "Volume Down" and "Power" held down performs a reset.

According to the User Guide, you hold the Power button for 10 seconds to reboot the device.

This is what I have to do with my Acer Iconia if I don't have a pin to push the reset on the bottom.

I'm not too worried, there will be some way to reset it if it's not one of the ways listed above.

Like I said, the method I stated is directly from the User Guide for this device:

The concern of many is that, at various time on various devices, something strange happens (might be a system bug nobody ran across before or perhaps even the users fault even when rooting or messing around with things) were NO hardware buttons respond. Not the power button, not the volume button, nothing. On several phones and devices I had issues like this if let the battery drain too much for too long. Then, even after charging back up, the device would not turn on without a battery pull first.

Not saying HTC hasn't solved this somehow, but I have $5 that says somebody, sometime will find themselves in a situation where they are stuck somehow and pressing on the power or the volume or whatever does nothing!

I could see that if this was a software function, but it's supposed to be a hardware function, in my understanding. Though, I did see an entry in the build.prop that seems to apply to the HW reset function:

Code:

# Support HW reset
ro.product.hwreset = 1

I actually considered throwing that line into my current EVO's build.prop to see if it does anything . . .

I guess we'll know more once a few of us actually have the device in hand.

Yes, time will tell. problem is that there would seem to still need to be some bit of code somewhere that tells the phone what to do if the power button is held down for 10sec or if the power button is held down at same time as volume key and so on. Unless it is a physical disconnect of power to the device, I'm sure one of us here will manage to screw it up at some point.

Doesn't Power+ Vol +/- =Hardware Reset?

Edit: Thats on the 3D.

Unless pressing a button physically interrupts the power supply through the physical act of pressing the button itself (which power+vol or power-hold does not do) like a true "on/off" switch, there must be some bit of software or code telling the phone what to do. And where there is software, there is a way to mess things up.

HTC may have things so well done that the buttons will reset everything fine, but its still not the same as a true reset button that interrupt the power or being able to pull the battery.

i remember my WM phones having a reset button.

It does. When mine either froze or stuck in boot loop after messing up with the ROM I held down volume down and Power and it reset

**Hurleygm** · 07-11-2012, 12:42 AM

This link HTC support multitasking/ proximity sensor says that holding the power button down for 30-45 seconds mimics a battery pull.

It could be hardware if there was some kind of "external" timer on the switch. That doesn't route through programming software. Going out on a bit of a limb here.

Also says how to get into safe mode.

Hold down power button for about 10-15 sec....when pop up comes up on your screen ignore it and keep it held down...you capacitive buttons will flash and phone will reset...its same thing as battery pull...
