Rebooting New Official GB without Pulling out battery...

It never worked me before Official GB Release.. I had to pull out battery everytime.. But now it looks easy..
Today I was messing with Phone root files and deleted system file and suddenly fell into a Focre Close message loop which was not ending... and at other time, My Desire hanged and was not responding...
Press in sequence Optical Trackpad button + Volume Down + Power Button..
The phone vibrates and then reboots fully...
But I couldnt manage to let it enter recovery... Maybe some trick you guys might know may allow it...
Let me know if it worked for u...

Or you can disable fastboot in menu->settings->energy->disable fastboot. So you can fully turn of your phone and boot in recovery

That makes sense... but if its somehow possible to enter recovery with it...

Stuck on loading screen :(

Hi... I have been using CyanogenMod for at while.. And it has been running great...
Then yesterday my phone started acting up, so i restarted it....
Not it gets stuck on the CyanogenMod startup screen when i turn it on...
And I can not enter bootloader, I have removed the battery, and then powered it on while holding volume down down, like I normaly do...
But i just end up on that CyanogenMod loading screen no matter what i try...
Is there another way to force it into bootloader or to force flash a new rom? (The rom i am currently on has been working fine for over a month, untill this happend)
I really hope someone has an idea... Please do ask if you need more info from me
Best Regards.

Hold your volume down before holding power button at the same time. Wait until it went into bootloader. If it is not, most probably your hardware keys is broken.

Hi... Thanks for your answer...
But that is how I have been doing it all the time...
Is there anything I can do? No way to force it into bootloader from the PC or anything?
Any advice is greatly appreciated!
Regards.
Looks like my volume down has broken last night
I was able to boot into bootloader using adb on the PC... So this thread can be closed

Stuck on "Entering Recovery..." after trying to update TWRP version

I tried to update the version of TWRP I was using(v2.7.0.2) on my HTC One M8 (rooted) to v2.8.7.0 using the TWRP Manager App that I downloaded from the play store. The screen is stuck on "Entering Recovery...". I would appreciate any advice anyone can give me about how to get out of it. I tried holding down the power button it does nothing. The screen is frozen. How do I turn it off / get it to boot properly? Please help.. :crying:

Holding down the power button for what feels like an eternity got me through this when it happened last. I also had to flash TWRP again.
Alternatively, I believe holding both the power button and volume down during this stage is supposed to work. The only other way would be to either grin and bear a battery drain shut down (Not good if the device won't take a charge afterwards), or pop open the phone / remove battery.. Which I'm sure you can find a guide for both here and online. Hopefully it won't come to that, though!

Thanks a lot! Holding down both the volume buttons and the power button at the same time worked for me.
