Can someone help me - stuck on htc boot - very strange situation

Hi everybody,
first I want to thanks to all xda members for there hard work.
I read many many threads on this forum trying to fix the problem I have on my desire, but didn't succed with anything........ very sad
here is my situation:
- I get stuck on HCT logo on white screen. I can acces fastboot, my pc recognize the phone with fastboot devices but I can't acces recovery, when I get to hboot than select recovery and press power button I get stuck on htc logo, nothing
I tried Paul's r6 root guide, done succesfully step1 with a gold card, with no error everything working well, but than when I get in fastboot and tried to acces recovery the same thing I get stuck on HTC logo screen and stuck there.
I bought the phone in these situation from a guy that has no history on it. Is from UK orange branded.
When I bought, it i had 0.75 Hboot and after run "RUU_Bravo_HTC_WWE_1.21.405.2_Radio_32.36.00.28U_4. 06.00.02_2_release_126984_signed.exe"
I got 0.80 Hboot.
So everything I tried I can't pass over HTC logo screen.
The strangest thing is that the volume down button seems not to work: when phone is off pressing volume down and power got me in HTC logo screen, and also when in Hboot only volume up work while volume down do nothing - what could it be?
So please if anyone know or have any ideea what should I tried to make my desire usable.
The HTC logo screen drive me crazy..
many many thanks

make sure your ROM is ready on the SD card for flashing and try getting into FastBoot,,, using back button + Power, and see if you can use the controls to get into recovery,,, its worth a shot

thanks for your replay, I can get in fastboot, but the problem is with the recovery, it doesn't work at all. From fastboot I go on the hboot and than move with volume up button (volume down button as I said do nothing - the strange situation) to the to line with recovery and when I press power button there is no recovery just get the HTC logo screen (not the triangle from recovery or any other recovery).
anothe rhing to mention that I also tried to load the PB99IMG.zip with Hboot everything works ok but after finishig install just got HTC logo screen........

you have a rooted Desire right??
Give it a re-rooting and flash with a brand spanking new ROM follow the instructions here;
http://forum.xda-developers.com/showthread.php?t=696189

I know that - but just doesn't work for me.
I can only acces fastboot and hboot - nothing else, but I tried r6 from Paul roting procedure step1 but can't get in OS of the phone - get stoc on that Logo.
possible a brick
I read the thread about usb-brick-unbrick but I can't do anything cause I can't get in the OS of the phone to lunch the emulator.

I bought the phone in these situation from a guy that has no history on it.

Has the phone ever worked since you bought it?

No, it never worked, from the begging it gets stuck on HTC logo screen, and never succed to pass with everything I tried.........

I am in the exact same problem. Can't access recovery, only Hboot i can access.

[Q] HTC Desire blank screen after stock update

Hi guys,
first time poster but long time follower.
Last night i attempted to load the stock 3 UK rom onto my desire so that i could recieve the ota update today of froyo but now my screen is completly blank. It shows nothing at boot up and nothing when on the home screen. I know it's on because i can see the keypad light up when i press the power button. I can't boot it into recovery mode because i can't see the screen. Also i don't have a gold card neither so im pretty stuck. I believe it has something to do with different version of screens but i didn't see anything labelled on the rom to say which is for what screen. My desire has the AMOLED screen. Please can someone help i've tried allsorts but i need to get it fixed or i may try to return it at three but im guessing they'll know i've rooted it. Thanks in advance.

hold the volume key down and power button and hold till phone powers up. if your phone is rooted and has a custom recovery u can boot into that and flash rom.

I bet you have a slcd screen. Look for slcd brick fixed.

I can't because i can't see if it's gone into the recovery menu or not.

I had this problem too, you can fix it tho.
Start the phone as usual, install HTC Sync first, then connect it to your phone via USB.
Download the HTC Bravo stock rom from shipped-roms, and then just run the .exe file, it will reflash the stock android OS and your screen will be fixed.

I am having the same problem guys. i tried to unroot and reflash with a stock virgin mobile ruu... would i use the bravo rom too?

http://forum.xda-developers.com/showthread.php?t=821656
as long as you can get to recovery (even if you can't see it), you should be able to fix it.
i fixed my phone fine when I tried to install a wrong amoled ruu and bricked my screen.
my solution in the thread above

Repaired
You try reflash your HTC Desire this ROM RUU_Bravo_Froyo_HTC_WWE_2.29.405.2_Radio_32.49.00.32U_5.11.05.27_release_151783_signed.exe. Me helped it.

[Q] stuck in HBOOT, S-On, unrooted, no buttons work

My little sister's G2 has been stuck at the hboot screen every time the phone boots. Her phone is completely stock, with the most recent (that I know of) update, the one in PC10IMG.zip. She didn't do anything to damage it at all, it just started booting like this out of the blue.
When at the hboot screen, no buttons work at all, the only way to get out of it is to do a battery pull. I even tried using ADB but it wouldn't detect the phone.
Any suggestions?

first thing i would try is to somehow wipe the phone... push power & volume down to enter bootloader; choose recovery (a red triangle or something like that should appear) then push power & volume up (the recovery menu should appear); then wipe everything...
if this doesn´t work post here again
EDIT: sry, just recognized that i didn´t read your post carefull enough... if your buttons do not work, you probably have to flash a RUU

i booted it with vol down+power, then i pushed vol up+power and it started searching for zips. I had pc10img on it and it found and tried to update with it, but it gave "main version is older! update fail! press power to reboot." and rebooting again brought me to the bootloader.
edit: i don't have any experience with ruu files, so if that's what i need to do, can you tell me how?

Search for a RUU which is similiar or higher than your actual version, download it and put it on your pc... on your phone push power & trakepad to enter fastboot mode, connect your phone with pc and start the .exe on your pc...
Before you do this remove the pc10img.zip from your sdcard and try what i posted before again...

i tried doing this, but it failed, saying that my phone model wasn't right or something like that. but it did make the phone boot into the rom! and it appears to have all of its data still, hopefully everything works now.

rebooting will make the phone enter fastboot still. none of the ruu files i've tried work. is there a link to one that will work? i haven't found any.

ok, before you do the ruu thing, try to do a factory reset (either in the booted rom or through recovery)
here some links:
http://forum.xda-developers.com/showthread.php?t=1074391 (this is a pc10img.zip - you have to put it on your sdcard)
or
http://www.filefactory.com/f/b8dc837b1ed80be8/ (...all official ruu)
pls use the thanks button

htsger 3
i used the pc10img you linked me to. gives me: "main version is older! update fail!"
i tried the ruu files you linked me to and those failed as well. they kept telling me my phone image was wrong or something like that.

Try some from shipped-roms

same error as above

I did some thinking and thought that getting it to boot by trying and failing to use an RUU, downgrading it, rooting it there, and then flashing another rom would solve my problems.
I managed to get to downgrading and rooting the phone, but after apparently flashing cwm through rom manager, I turned off the phone and tried to boot into recovery by vol down + power. Those are the buttons I use to boot my g2x into recovery, and through searching I didn't find any other combos for the g2.
That didn't work. I got sent to fastboot again, and no buttons work. I then tried RUU again, and this time it worked, booted. I turned it off and back on to see if it would actually load the rom this time. Alas, fastboot screen again. Still no working buttons.
I tried the PC10IMG.zip again. It flashed, but when it says <Press power to reboot> and I press power, I get sent to fastboot.
I pretty much consider this phone a lost cause, but if anyone has a suggestion that might help, please tell!

I can only tell you that I have same problem, just happened to me y/d and I am stuck on white HTC logo not having adb access and can not flash any stock rom for signature errors. not sure how to continue. thread is: http://forum.xda-developers.com/showthread.php?t=1614042, good luck for both to solve it

Help getting back from semi-brick

Something has gone very wrong with my HBOOT.
Whenever my phone starts, it always goes into HBOOT without pressing any keys.
In HBOOT, I cannot press any key, so I can't get into Fastboot
I was able to get out of it once by running "ADB reboot", at which point I put a stock ROM back on, which slightly downgraded HBOOT from 0.85.0024 to 0.85.0007, but when I rebooted I was right back into HBOOT, only now I can't detect the phone in ADB, so I can't reboot it from there.
So I'm stuck on the HBOOT screen, and all I can currently do is auto run a pd98img.zip file, but I don't know what to try auto-run. Can I restore an S-off boot using a file, or do I need to use the ace root kit?

If your phone goes straight to hboot then seems that your volume rocker might be broken or stuck. Check that first. If you can not navigate in hboot could be a corrupted sdcard, so take it off and try booting again. If your volume rocker is messed, then try fixing that first otherwise success might be difficult. :good:

Strangest thing.. you were right about the volume rocker, but it was a weird problem. Several months ago, I had replaced my battery with a 2000mha one and it has worked well until now, but as I was getting ready to get the phone repaired, I swapped back to the stock battery, and the rocker came back to life! Who knew. So I am back and re-rooting and rom'ing as we speak

Have you tried flashing a stock recovery via fastboot? Or flash TWRP again then flash a stock nandroid backup from the backup/recovery thread?

m8 white screen
Good evening community
I think I bricked my M8. Tryed to flash a custom ROM, unrooted and installed it but didn't liked and decided to go back to stock ROM. Went to TWRP and wiped one position more than needed - data. So now my M8 booted just into white screen with HTC logo, power off doesn't work at all, hard reset combination doesn't work, power on + volume up - doesn't work. It's always on and CMD says <waiting for device>
Who can help me?
Thank you in advance
Edit: got into bootloader, thanks to Niorun post edit.

For this phone, as long as the screen comes on, its almost certainly not bricked.
Being stuck with OS not booting is a common thing when flashing ROMs. It just happens from time to time for one reason or other. Folks that freak out about this (and think their phone is bricked) need to relax and learn some basic recovery steps.

Wiping data will not make the phone get stuck on the HTC logo screen. Wiping data just erases user data. So the phone would have just booted into the OS, but with no previous user data present any longer. Failure to boot was for some other reason.

Power + Vol Up reboots the phone, this should always function as long as the screen comes on.
Power + Vol Down to boot into bootloader similarly should always work as long as the screen comes on. Failure to do so is almost always a matter of user error, not performing the button combo correctly (either not pressing vol down fast enough, or letting go of it too early).

Power + Volume Down
So, in response to

Try it this way:
1) Reboot the phone using Power+Vol Up
2) The moment the screen goes dark to reboot and before the white HTC logo screen appears, let go of the buttons, and hold the Vol down button. Do not let go of vol down until you see the bootloader screen
3) If the bootloader doesn't appear, you either started pressing Vol Down too late, or let go of it too early. Just do the steps again until you get it right.

Clarification
I have to anticipate when the screen is going go from black to showing the white HTC logo? Then do vol down then?

htc m8 brick
i too am having issues with a bricked htc 0ne m8. We purchased the phone as-is really cheap. its freezes while booting up. i can get into fastboot and recovery just fine. i have been successful in installing ruu files but the ruu file doesn't fix the "boot loop" freeze at startup issue. The device is s-on still which sucks because i can't find a method of achieving s-off in fastboot mode. i was able to unlock the bootloader, hoping that it would help and now the ruu files won't work anyone. now i can't get the bootloader to lock through the method that htcdev.com tells me to use. ive also tried to install update through adb sideload through recovery without success.
so i have a s-on, unlocked bootloader htc m8 that i still can't get it to boot up.
any help would be appreciated.

I just timed it (in my head, not with a stopwatch), and you have about 3 seconds while the screen is black, before the HTC logo screen appears. Plenty of time to let go of the power and vol up buttons, and hold the vol down button.
The reason I say "the moment the screen goes dark" is that some folk wait too long, and start pressing vol down when the HTC logo screen is already up. By then, its too late.

What CID (or original carrier version)?
What RUUs did you try?
Don't know what method HTCDev says to relock the bootloader, but as long as you can still get into fastboot mode, its simply the command: fastboot oem lock
Also, there is no other currently working s-off method aside from sunshine (which requires booting into OS) so you can stop looking for one.

I "Softbricked" my htc one m8 AT&T
i recently rooted it and made 4 back ups. I deleted two of them and tried to roboot to fastboot. but it says 'No OS installed" . My computers reconize it as a disk drive and when i click on it, it asks me to insert a disk...Please, ANYONE with information that will help, share

Well, you say you can't get in the bootloader or recovery, have you tried to hold down the power button and volume up button, and then when the screen goes off switch to power and volume down? That should take you to your bootloader! If you can get there I would guess you would have a backup in recovery

It doesn't. The tool is very outdated, and I typically (virtually always) recommend against using it for that reason. The toolkit uses the old firewater s-off method, which hasn't worked since December 2014.
When I said there is no other working s-off method besides sunshine (and to stop looking for one), it was a statement of fact, not a guess.

I need some help, I have a m8 rooted and to make an update from htc (I have te stock rom) I have flash de stock recovery (te old one was the twrp) but now after the update de phone is stuck in the htc logo, I can enter in the fastboot but I dont know what to do and what direction I should take

Follow my steps if your phone is not booting up.
1. Lock bootloader if you have unlocked bootloader.
2. Download HTC One M8 4.16.401.10 Stock Lollipop RUU [0P6BIMG] ( search google because I can not post link since I am new forum member).
3. Rename the downloaded RUU to 0P6BIMG and send the zip file to your phone SD Card.
3.Reboot your phone in to the bootloader mode by powering off the phone and rebooting with Power button and volume down or use fastboot mode command : adb reboot-bootloader.
-This way our phone will automatically detect the RUU file that you pasted in SD card (step 3) and flash it.
Your HTC One M8 is alive

The advice given here is good, except it assumes too many things. There is the assumption of S-On, and of current firmware version. Also, if you are using ADB to reboot to bootloader, the user might as well fastboot flash the RUU.zip, or run the RUU.exe that is also available.
@W_KuP, Post the results of fastboot getvar all (edit out your IMEI and serial# ~ that's private info)
If you are indeed on WWE/International firmware, that RUU.zip will work for you. Download link here.
If you are S-On, you will need to relock your bootloader first. In fastboot: fastboot oem lock. If you are S-Off there is no need to relock your bootloader.
