I touched on this in a couple of threads in development and want to get an idea if this is an issue all Inspires. We get into Hboot/Recovery mode by holding the "volume down" and "power" for about 5 seconds. For me though, this doesn't work when the phone is completely shut down. It works great if I does this during a restart though.
Why this matters?...Let's say you flash a ROM and can't get past the white logo (happened to me many a day on the captiavte ) without being able to enter recovery mode the phone will go into an endless bootloop.
Let me know if anyone of you have any issues entering hboot/recovery from shutdown.

Tricky or impossible . I've been trying for the past hour. What did you do to get it to work?
Geesh. An hour later still no luck entering recovery from shutdown.

So if you have a bad kernel or Rom there is no way to get back? That Is quite worrisome, making me reconsider the captivate...

Percisely what concerns me.
I'm sure you remember that on the Captivate, you can hold volume buttons and plug in USB to go straight to download mode as well. Maybe the Inspire is the same way?
EDIT: I do have CM installed, but I held Volume Down and plugged in USB and it went into Recovery.
The phone hasn't even been out a week; I'm sure all these things with kernels and radios will become easier and more clarified with time.
As far as booting into recovery goes, I'm still not sure what the deal is.

Soved. Disabling fastboot corrects things.

You mean disable fastboot on a working phone... lol. That's the potential issue I think we are concerned with. Isn't fastboot in the settings?

Yes but apparently a battery pull while the phone is off works just the same if you forget to disable fast boot (as I'm sure I will do )
I don't know what it is, but I've yet to be able to get it into recovery mode via the buttons. Well...that's not true, I've gotten into recovery after a battery pull by volume-down/power, but that's it.
Been having a lot of difficulties over the last day or so with the sdcard unmounting, usually accompanied with the error in the status bar. And apparently Rom Manager won't do reboot into recovery if it doesn't see the card :-/
So I've had several times now where I've wanted to get to recovery, and have to either get back to the computer for adb or do a battery pull.
Anyone else have troubles getting into recovery? I did disable the fast boot option in settings. (took me a minute to figure out that's what you guys were talking about, lol)

I've been seeing this the last day or two as well. Ejecting/Re-inserting SD card will usually remount ok. Anyone else seeing this?
I wasn't able to get to recovery from power off until I turned off fasboot, but then it booted right up with vol-/pwr.
Yea the 8gb card the phone came with, when I do a restart would not mount correctly once I got the phone booted back up, so I put a 16gb card that I had lying around into the phone and it doesn't do it now in a restart. Must be those cards that shipped with the phone, unless yours is doing it on a after market card.
Sent from my HTC Inspire 4G using XDA App
It's done it several times today. Just a few minutes ago I was browsing inside a zip file on the card with root explorer and then it cut me off with the error message that the SD card was unexpectedly removed.
Oh and I was able to enter recovery from a power off condition as described here (fast boot disabled in settings) But is there a way to do that when its on? Like with the N1 we can press volume-down/trackball/power and it will force a reboot.....anything equivalent on the inspire?
No reboot option in powermenu?

***Really Solved***
So, pull the battery, take out your SIM (just in case) and your Micro SD card. Then hold down Volume Down and then press and hold (for a moment) the Power button; release the power button after a moment while continuing to hold the Volume Down button. The Bootloader screen will load up and you will now be able to use the Volume rocker to select Recovery. As soon as the phone starts to reboot in to Recovery put your Micro SD card back in. I know this works because I just saved myself from what I though was going to be a Warranty claim.

Thanks a million...after flashing a different rom on my Inspire, I had a hard time getting into recovery mode...it most definitely worked best doing a restart rather than a full shut down!!
I screwed up a flashed a ROM from recovery that probably shouldn't have. I am unable to boot my phone (inspire 4g) and hangs at HTC screen. I can enter HBOOT screen however, recovery mode doesn't work. It's if the files needed to load into recovery aren't there. Any fix for this?
Thanks in advance
to enter recovery on DesireHD/Inspire 4G you must have your device booted up and hold down the power button. After that choose reboot. Then choose Recovery and press Ok. If you have a recovery installed it will reboot into that recovery if you have no recovery im not sure what will happen

HELPPPPPP i got to the stage where it says press power button once to enter HBoot then press enter on your keyboard. It did that and then i pressed enter twice on the keyboard. then what was supposed to come up was the part where it is supposed to say your phone should now search for the PD98IMG.zip. but it never did. then the computer said that it could not recognize the android driver. now the command prompt box is stuck at *daemon started successfully* and is not doing anything and has not for the past 10 min. should i turn off the phone and start all over?
Got it! Now i have to figure out which custom rom to install.Any suggestions??Guess it wasn't that hard after all. Thank god i have a son that knows how to do it!!

You still have a PD98IMG.zip file on your SD card. As long as this is there, bootloader will always try to automatically update with this file through HBoot. You need to remove this file from the SD card and you'll be able to boot to recovery

Then you some how doing it wrong then because every person I said that too has said that it helped them get into the bootloader. As soon as it turns off let quickly let go off the power button but still keeping hold of Vol- and then press and hold the power button. And as added bonus flash TWRP recovery when you get into the bootloader then you wont have it booting into recovery like it's doing now.

Em not really most of it is copy and paste anyway but before doing that I think it be best you flash TWRP recovery so it should be easy to get into the bootloader again.

Hey everyone I have a HTC inspire which I flashed jelly time onto, before that my volume buttons worked but now they don't work and the button is complety gone HTC did a very bad job with that it easily came out... So recently when I boot the phone on it boots the normal jelly time startup and the black screen. I have seen the only way to fix this is either factory reset or reflash ROM. But I am unable to do that since ,y volume button is broken. I have read that you can get to recovery via adb and or flash via adb can someone help me out please?

you can connect your HTC phone to your computer via USB cable, and use the command below, before that you need to install adb shell on Windows.
adb reboot bootloader
Also, you could enter Recovery mode through ROM Toolbox and if you're using TWRP, its touch, so you dont need hardware keys.

So you're stuck on booting and your hardware buttons dont work?
There is a way to get into the recovery in such a situation but that usually relies on the hardware buttons. What device do you have? What recovery?
Try this
Remove battery n reinsert it
Now connect the phone to charger.
Don't do anything keep the phone as it is for 5 -10 min.
It will automatically go to recovery

Follow these fool-proof steps:
Locate your android sdk folders-> navigate to the folder where adb is located ->hold shift + right click on the folder containing adb and select ''open command window here'' ( this will automatically take care of pointing the directory to that location) -> 'adb reboot recovery' ENTER
This will automatically enter recovery. I suggest you restore your old backup .
As for your volume buttons, you should be able to fix it easily if you know a little bit of soldering and know-how.

HTC Desire HD hard reset without volume buttons
I have htc desire hd and my volume buttons is broken ,my phone is much dispute and have lots of bugs i want to HARD RESET no factory reset only hard reset with rebote. Please help me how to reset my HTC DHD without volume buttons!!
!!sorry for my english!!
SOLVED! (At least for me)
To whom may still be interested, I found a way to get into recovery and subsequently wipe data/factory reset the HTC Inspire 4G/Desire HD without using the volume buttons.
Phone background: the phone that I used had the internal volume buttons broken. It was rooted and unlocked using the effen hack kit, then I flashed a custom ROM on it and I forgot to do a factory reset before I firstly boot up the phone with the new ROM. So it was stuck on the boot animation forever.
Steps for getting into recovery mode without volume buttons:
1. Take the battery off
2. Plug the phone to a wall charger for at least one or two minutes.
3. Put the battery back on along with the battery door and don't touch any buttons.
- The orange led on the front will light up and stay on for a few seconds before the phone automattically gets into recovery
Note: use the touch capacitive buttons to manipulate recovery:
- Home/Menu buttons to navigate up/down
- Back button to go back
- Search button to select
That's pretty much it. At this point you can do anything!
I hope this can help someone out there... If it helped you please hit the thanks button!

You can use adb commands to enter in recovery mode. Connect your android to PC. Enable adb debugging and open command prompt in PC.
Type "adb devices" without qoutes and enter then type "adb reboot recovery" and enter. These commands boot your android in recovery mode.

You may need to uncheck usb debugging in developer options then reboot and go in and check usb debugging again then try adb tools using adb devices and see if it works then. Some m8's can be a real pain that way you just need to keep trying.

I would run the newest ruu that dottat has posted in the android development section for this phone, put it on your sd card using your computer, then put it back in your phone and boot to fastboot and let it pick it up and hit I believe it is yes and it will restore your phone. You are on 4.4.4 right ? If you are having problems getting to fastboot hold power and volume up until you see the lights change and or it vibrate then quickly switch to power and volume down and it should take you to fastboot, it may take you multiple tries to get it there. This sounds like the screen of death issues people have had on viperone which the fix for that so far has been to reverse the 4g handoff fix as most people that have the sod they had used the 4g handoff fix but if you cant get past the black screen then you cant do the fix for that. Have you tried leaving your phone sit for a while to see if it comes out of it ? Also most people only had that issue in weak signal areas so a good signal area could get your screen working again if you had done the 4g handoff fix. If you did some have said that the change can stick even through a ruu, but I cannot verify that either way.
Can I say I'm having an almost same problem.
I wiped my phone in prep of loading a new rom.
RUU the firmware for 4.4.4
Loaded twrp
and then it rebooted to the htc screen.
Now I can't get past that screen. I can hard reboot but it only comes back to that screen. and if I try to access it through the computer it can't load the driver so that I can sideload.
Help please

it's tricky to get it back to hboot... but you can with practice. Hold power a both volume buttons until you think it finally has rebooted. Switch to only holding vol down to enter hboot. Timing and practice makes perfect.
It took about an hour of trying. But I did it. Plus I had to do a few other things to get things remounted.

Once I was back in recovery I reformatted before rebooting and then from recovery I installed the rom.

I agree with Dottat, faced the same issue when trying to flash ARHD 22.1 on my Verizon M8. I think I sprayed some **** in my pants with that loud fart .
After trying several times I got the trick and could get into Hboot. The issue I think was I was holding Power + Volume up & down for more than required time and it Rebooted. We need to Switch Off the device by Holding Power + Volume UP & Down button for about 8-10 secs and then just remove the finger from Volume UP button. It takes you to Hboot mode..
