[Q] How to get into HBOOT. - EVO 4G Q&A, Help & Troubleshooting

Sorry if this is a noob question but how do you get into hboot. I just got the evo came from a rooted hero. I understand that the new evos have not been rooted yet. I have powered on the evo and held down the volume up and down keys, and it just makes my evo boot up faster.

Turn the phone off.
Pull the battery.
Hold down Vol Down button
While still holding the Vol Down button, put the battery back into the phone
Continue to hold the Vol Down button until you are in the boot loader

Thank You that worked.

No problem! Glad that worked for you.

Without the battery pull, you just need too change your fastboot selection to off in settings, then you can power down, and use the button method

[Q] Cant access bootloader on leedroid 3.0.5

Hey all,
I am running leedroid 3.0.5 on a HTC Desire and I want to install another ROM. I went to run bootloader by turning the phone off, holding down the lower volume button while hitting the power button. The phone is just restarting but in a quicker than normal mode. I have tried this a few times and it is still the same. I tried also hitting the power button and then holding down the lower volume button - this just brought up the HTC logo and the device was delayed for several minutes.
Can anyone tell me what is going on or what I can do?

Hey. Anyone else have any idea's? I turned off the setting as you suggested but it is still not working.
Takea out the battery. Wait few secs. Put back. Hold POWER + VOL DOWN.
Pull battery and try again. If it doesn't work then it may be that your volume button is acting up. If that is the case, pull battery and press power while holding down the back button. This will bring you to fastboot menu. From there select the first option to enter bootloader.

Thanks guys. I got it working by pressing the back button instead of the volume down button.

[Q] Stuck in bootloader, HELP

My phones stuck in bootloader and it doesnt respond to both my volume buttons and my power buttons. Anyone have any idea how i can fix this? Also when it boots up it looks for a file called pd98IMG. Ive tried putting it onto my sd and the phone boots into bootloader and loads the file but it still stays in bootloader.
The phone is also rooted and i was running android revolution
Anyone who has the answer to this gets a reward, most likely to be cash. Thanks
Pull the battery, put it back in and power and - volume down should see you to recovery and just reflash your current rom.
It doesnt boot into recovery when i do that, it just boots into bootloader every time
I think i had the same problem a while back, the trick here is speed As soon as you put the battery back in try and get into recovery.
Take the battery casing off and the battery slightly out, now push the battery back in and press the bottom of the volume slide and quickly hold the power button down for a second, than release the power button still holding the volume down, you should now be in hboot, wait 2 seconds than go to recovery.
thats not working either, you got any other ideas?
Would you have adb?
Try this http://forum.xda-developers.com/showthread.php?t=1304940&highlight=stuck+in+bootloader
i get error:device not found, how do i get rid of this? :s
Is it still bootlooping? There should be a sweatspot where it works just as the led lights up, simply a matter of timing. Though i would give the battery out hold power and volume down and put battery in approach another go if all else fails.
nope, my laptop doesnt recognize my phone as its in bootloop so therefore i cant really use adb with it or anything,
Just want to make sure, as soon as the phone is powered off, it goes back on by itself automatically? If so take out the battery plug it in put the battery back and try to boot into recovery with charger.
i cant power the phone off using the power button, i have to remove the battery since its stuck in bootloader and the power and volume buttons dont work in bootloader for some weird reason

ROM Manager Hard Bricked My Phone?

I wanted to update my phone from CM9.1 to CM10 and wanted to back it up first. The first backup never went past "clearing space..." so I cleaned out all of my old ROMs and a couple of backups. Then I thought, maybe I don't have the latest version of recovery, so I reflashed Touch recovery. Then I hit the "reboot into recovery" in ROM manager. The phone vibrated and "Samsung" boot animation appeared very briefly....then nothing. I tried pulling the battery and then holding going directly into recovery with the volume buttons and power and it would just vibrate and show the opening samsung boot screen. After trying that a few times, now all I get is the vibration.
Today I tried the "soft brick" solution, but all it does is vibrate every alf second.
So am I bricked?
Your are soft bricked.
Take battery out for ten seconds
Insert back in hold volume keys press power
Let go while continuing holding volume key. Some people hold volume keys and power continuously but that doesn't always gets it.... g luck

To enter recovery, your timing during the phone vibration has to be somewhat perfectly timed.
Power up and keep one finger in the middle of the volume control so both volume controls are pressed simultaneously with one finger on the power button. When the phone vibrates one time, remove finger holding the power button while still holding the volume buttons until recovery appears.
Good luck OP.
When I do this, all I get is a black screen after the initial Samsung boot screen. Am I supposed to follow the instructions on the soft brick thread? Or just do this over and over until something else happens?
Good news guys. I used the soft brick instructions and loaded recovery through odin and it booted up into CM9 on its own! Thanks for the help!

Have you tried holding volume up and down at same time while holding in power button at the same time plugging in the power cord this will get you to download mode so you can use odin to flash new rom if possible. Or just turn power on while holding down volume button while it powers up this will get you to download mode without the power cord also.

[Q] can't acces HBOOT. Help please

Hi,
I'm trying to root my HTC One V following this tutorial, but got stuck after succesfully unlocking bootloader. I got to point 18., then confirmed unlocking and the phone turn on. Then screen where you type your pin apeared. So I hold down POWER button and choose to turn off the phone. When it's turned off I press VOLUME DOWN and hold and then press POWER and hold but the phone always just turns on istead of going to HBOOT. Now I have no idea what to do and I don't want to try things on my own because I might brick it or something. Help me please
11 hours, first reply
@KaCZeR2
hold power button for approximately 10 seconds. you will see out hardware keys at the bottom of the screen start to flash and then your screen will turn off.
as soon as your screen turns off, release the power button and then hold down the volume-button.
this will boot you into bootloader mode.
:thumbup:

Help with brick?

Hi I was running the Cyanogen Mod Nightly for my phone, and hadn't updated it for about a week. When I went in to my settings to update it, I downloaded the latest one and when it was done it prompted me to start it, so I did. It got to about 2%, and after that it's been looping in boot. The screen flashes on and off instantly every 5 seconds. Power + Volume Up works, it shows the HTC screen and says it's going into recovery, but then it just loops in boot again.
Is there any fix/hope for my phone?
Press power + vol up, and as soon as the screen goes black, press and hold power + vol down. You will boot into the bootloader. from here you can flash an RUU to go back to stock

So I tried doing this, but nothing happened.
I did however, fix my problem, by holding down Power + Volume Up until it showed the initial "Booting into recovery" screen (which was failing), but kept holding Power + Volume Up until the Battery Charging screen showed up (I had it plugged into my PC). Once I let go, it rebooted the phone normally, and started up Cyanogenmod. Now the phone works, so I am going to back up my data, and switch to a non-nightlies version (or just never update).
Thank you!
Next time if you are in a bootloop, just holding vol down during the next restart cycle will get you to bootloader.
If the buttom combo (Power+vol up to force a restart, then just hold vol down to go to bootloader) doesn't work, its virtually always due to getting the timing wrong (either not pressing vol down soon enough, or letting go too early). And the fact it was looping makes the timing tricky. But holding vol down during a bootloop (restart) will always get you to bootloader.

I already tried that, it would automatically go back into a bootloop. And I tried your second option, which also didnt work. The only way I personally was able to fix it was having it plugged in, holding Volume Up + Power through the bootloader screen (which would crash) until the battery icon with the red disclaimer text showed up. Then it would reboot without going to bootloader (Pretty sure the Cyanogenmod tried to get it to this and failed).
Still cant get it to update without crashing so im just going to flash a new rom.
