Phone boots slowly in fastboot and canno't do hard reset! - Desire 816 Q&A, Help & Troubleshooting

Hello,
my friend gave me his HTC Desire 816 to fix it. Phone originally boots up in fastboot mode, but very slow and unresponsive. To describe it, when I push the power button to turn it on, only after 30 seconds the androids on skateboard image shows up and it takes approx 20 secs to get in fastboot. Then again, it has laggy menu in fastboot and I tried to do factory reset but after hitting it, it only shows androids on skateboards again only for few seconds then just turns off.
Phone has bootloader locked and It canno't boot normally.
Please help me and my friend.
Thanks community, you are the best!

Bump!

Try the htcdev unlock process and see if it works.
If so you should be able to put twrp 3.1.0.0 on it.
You can also try to
fastboot boot recovery.img
Replace recovery.img with whatever the exact filename is for the a5 twrp

Desire HD boot problem and can't reboot

Hi guys
I've got a desire Hd, over 2 years old now so out of warranty. Not rooted, Android 2.3.5 (official ROM), Middle East ROM and relocked.
When i turn it on,After a minute or less, when it would normally show an android screen, the screen goes to bootloader. and when I wanna reboot it or enter to the recovery , the screen goes blank but the phone is still on, and the screen is still on but in a very dark grey. if you hold it on an angle the backlight appears to be on. But from that point nothing happens, the buttons no longer respond, and I have to remove the battery to turn it off.
Although I've tried to reset factory my phone but it didn't work and the screen goes blank again when the backlight is still on.
Thanks for your help.
PLease help me asap.

nothing much. I've just removed the battery many times, because the Volume down didn't respond and I wanted to enter to the bootloader!!
any solution?!! :crying:
try this:
What happens after putting battery back whitout pressing the ON-Button?
If it's still off, try pressing once ON-Button AFTER holding Volume-UP till HBOOT comes... maybe your phone need that
OR:
Connect the phone (when its off) to PC. Then turn phone on. Flash the boot.img over PC with fastboot.exe (only boot.img, not hole ROM). I had the same troubles with every ROM i tried, i had to flash it manually.

Does it needs any RUU to do this or the boot.img is already exist in my phone?! (my phone is S-ON and relocked)
and what's the exact command to flash boot.img not the whole ROM?

Once you're in the bootloader, and assuming your computer has the correct drivers and img files, type in CMD:
"fastboot flash boot boot.img"
I think I'm in a worse condition than you. My phone won't even boot into bootloader, have tried all the hardware keys (Vol+-, Home, Back, Menu) with Power button. I have even tried taking the volume cable out and pressing the buttons directly but my phone still goes into the boot animation and then blank screen with backlight on. My computer is also not recognizing the phone so adb doesn't work. I'm out of ideas, anyone got any?

I did it but unfortunately I faced with this Failure:
Code:
C:\Android>fastboot flash boot boot.img
sending 'boot' (2840 KB)... OKAY
writing 'boot'... INFOsignature checkin
FAILED (remote: signature verify fail)
what should I do then?? :crying:
and about your problem i think the Volume Key is the problem and it can be fix by replacing the volume key or even with a simple cleaning. don't worry

Fastboot Reboots Normally Abnormally.

Hi, I am having an issue with my Asus Zenfone 2. The title says it, it's pretty normal, but at the same time it's not normal. I have been trying to flash a recovery in fastboot mode, but I can't. Once I get to the fastboot screen, it starts counting down seconds from 5, and it won't let me flash/send the file successfully, and my phone simply turns off and turns on normally, a normal reboot.
The only problem is that, it doesn't stay in fastboot mode, it restarts in 5 seconds after you get to the fastboot menu.
Does anyone know what can I do to fix that? I have no clue why it does that.
Thanks
Anyone? :/

HTC 10 stuck in fastboot

I am stuck with bootloader. Couldn't not enter recovery. Flashing from bootloader again and again didn't work. Couldnt enter download mode either. It goes into download mode then starts restarting. Tried RUU, it says low battery. When tried power off it and put to charge, charging icon comes and then restarts again and again.
N.B. DDR test looping, message on fastboot screen

I think you are the 4th or 5th member whom has posted about this issue. I don't think any of them came to any solutions, but search for the threads, I haven't been keeping up. Sorry to hear this and hope you get it resolved.

You wiped system, which is the OS. So of course, you have no OS to boot to, now.
I assume you did this in TWRP. Any previously created TWRP backup to restore?
adb will only work in OS (which you don't have of course) and TWRP, and if debugging is enabled. Fastboot will only work in bootloader-fastboot mode (debugging not required to be enabled). So neither adb nor fastboot can be expected to work "stuck" on the HTC logo screen.
Hold power+vol up for a minute or so (I'm guessing you just didn't hold that combination long enough), until the screen goes dark, meaning it is about to reboot. The moment the screen goes dark (but before the HTC logo screen appears again), let go of those buttons, and only hold vol down. This should boot you to bootloader, where you can then use fastboot, or boot recovery. If you fail to see the bootloader screen, it is almost certainly a matter of you just not getting the timing right. You either started pressing vol down too late, or let go of it too early. Just repeat the process, until you get it right.

HTC M8s wont start even fastboot aftrer unlock bootloader and flash recovery

I get new HTC m8ql_ul, first i unlock bootloader succes. Then flash twrp-recovery-2.8.6.0-m8s-qlul also with no problem. In TWRP i flash new rom, but gets problems. eg after start didnt see sim card. And after plug to comp, and set data transer not charge pc didn see my phone, also in twrp cant see or fastboot also. I tryed fiew times flash difrent roms. but also same thing : when install via aroma, never get 100% but eg stuck at 30% after fiew sec show 100% and info about succesed flash but stack on HTC logo.
But now when i off phone pressing ~10s power, afrer this push power + V+ and nothing, no bootloader no flashboot no reaction, when press only power phone start display big battery icon and thats its, must ~10 power to off icon, even not plugged to pc.
What can i do? Flashboot didnt see phone. Pliss
for me plugging my HTC one m8s into an wall outlet, and pressing the volume down and power button gets it to boot into recovery, im no expert at this by any means, but hopefully this helps!
