You have HTC black screen with 4 (!) points in corners?
Just rerun RUU again, make sure its the correct RUU *& short data cable.
RUU(.exe from computer) should still run with this screen on
Opps sorry did not see the HTC logo was not there until posted!!!

Any solution ?

Leave it to a wall charger for a few hours.
Later press & hold all power+vol up+vol down buttons for about 3 minutes and advise the outcome.
Which RUU that you flashed ? What's your firmware no. ?

I was trying to update to firmware 6.20.651.3 updated successfully

Just posting you have the same problem, is not enough info, and is never the right way to post.
You were updating firmware 6.20.651.3, it was successful and now the screen is dark and the device won't boot?
You have the Sprint version phone?
Or did you not even mean to quote the previous post referencing firmware 6.20.651.3; and just have the black screen problem?
Its not clear if you give zero details. Nor is it possible for us to give you much help.
Describe your issue in detail: what version of the M8 you have, what Android version, what was happening when the issue occurred. What things you have tried so far. Describe everything specifically, step by step; and provide as much detail as possible.

Yes, you are right, I'm sorry. So here's the full story. Friend of mine gave me his HTC One M8S, it was stuck in recovery. Here are the first screenshots:
https://postimg.cc/image/kp35x8n9z/
https://postimg.cc/image/p61e8t837/
After that I unlocked the bootloader and installed TWRP (i think it was 2.8.6.0). Then I tried to restore it to stuck ROM, I found this thread:
http://forum.xda-developers.com/htc...lp-thread-htc-one-m8s-to-stock-howto-t3190238
So when I tried to do that (I used HTC Europe 1.03.401.11 image), update started just fine, after some time my device just shuts down (it was connected to charger so It was not that battery was dead) and after that I was unable to turn it on.
When I connect my HTC m8s to charger red led light is blinking, but the phone is not turning on. When I connect my phone to pc, fastboot and adb are not working, strange thing is that my pc is recognizing my phone like unidentified device.
So any ideas? Is my phone gone?
Thx

Try charging it for a few hours. Then hold power+vol up for a minute or so, and see if its boots at all (at least to the bootloader screen).
Neither fastboot nor adb will not work when the device is powered down like this.

I tried that already, still nothing..

I've bricked my flatmate's Desire? [FIXED, thanks]

NOTE: THIS ISSUE HAS BEEN FIXED, See this post #97 by "teppic74" for how I fixed the phone
My flatmate recently got a Desire from Vodafone, it's got their latest ROM on it with all their bloatware.
I told him I could debrand it, but the goldcard method didn't work because he had bootloader 0.83.
So I followed a thread to this site on how to downgrade the bootloader:
http://www.tolxdorff.net/tutorials/?step=2
So I did step 4... and then the screen went blank. I left it for a while, I thought it may be installing...
After a long time, I pulled the battery out and rebooted the phone ... I'm pretty nervous by this point LOL
Anyway, the phone reboots and I can hear the annoying HTC chime, which never happened on the Voda rom...
But I can't see anything. It appears that the phone is booting up, but the screen is not working.
Anyone got any advice on what I might do to fix this or am I toast? Grateful for any advice.
Have you try it again or download a original rom (maybe on vodafone...on my o2site it give a original rom and also here on xda)...or have you tried unrevoked...what say the h boot now..?????
with kind regards...Alex
Unforunately that's the problem... the phone is working and booting up, but the screen is blank... so I can't see anything.
I'll try to find and flash the voda rom, that's a good idea

you have no acsess to bootloader or recovery.....??
try vol down (hold it) and phone on (power)...
Well... I think I can get into recovery... it's just I can't tell because the screen is not showing anything...
if I was to make a noob guess at what's wrong, and this is unsubstantiated, it's that it's a new desire with SLCD screen and that it's get the driver for the AMOLED screen installed when I downgraded...
Two more people over at modaco at reporting the same issue, I think:

Test your theory.
Pull out the battery and put it back in.
Press and hold volume down and birefly press power on.
Keep volume down pressed for 5 seconds, then release it.
Count 20 seconds, then press the power key briefly once more.
You should now be in fastboot.
Connect your phone to the USB port and it should list it self when you execute fastboot devices.
If see it listed, you can restore the original ROM via the vodafone RUU file.

Correct that's me.
I tried a normal boot, unrevoked found the phone but got stuck waiting for boot loader.
I did follow the test you mentioned regarding fastboot.
Windows did make a bleep bleep sound when i plugged it in, but when I ran adb devices (is that what you meant when you asked "is it listed"?), there were no devices listed.
The phone does make the annoying htc sound on normal boot... just no screen

ADB will not find your phone in fastboot. You need to download fastboot binary and run fastboot devices to list devices in fastboot mode. If you use windows, you also need to install the fastboot windows driver. (I think you can find that in the android SDK)
I no longer even get the startup beep. Think I am totally screwed?

I'm getting the bleep bleep cause I tried to install the generic rom... you're probably not getting it because you only tried to root the existing rom, is that correct?

[Q] Phone dropped into water, can I RUU back?

Hey guys!
I need a little help: my phone has rebelled against the law of physics and somehow slipped from the side of the bath into the hot water. Basically everything works, but the screen's touch.
No problem, I've made a contract with my carrier for such case.
But I'm running Cyanogenmod 10. I'd like to RUU it back to Sense. Should I try it before I take it to the carrier? Do I have to interract with the screen during the process of RUU?
I've connected my phone in fastboot mode, my computer recignizes it perfectly.
Thanks for your help!
Bump.
You're phone will not be repaired if its water damaged.
Its beyond "economic Repair"
Sorry :/

I know, but as I had stated I have made +warranty with this device for such cases with the carrier.
Nvmd, starting to RUU back.
Since it is obviously not a software failure i don't think you have to revert back to stock. I am pretty sure it will work to go back as far as "fastboot devices" and "adb devices" gives you back an adequate info.
If it was me and i had some spare time i'd revert it anyway, just to be sure.

Howto is ok. Stick to it. Plug in the phone to your wall charger first to make sure you have got enough power. In the fastboot bootloader you can see your current H-Boot but not if you upgraded it. If you can't remember doing anything to your H-Boot you didn't upgrade i guess...

The battery should be around 90%. How can I stop from constantly rebooting it? I can't even turn it off.
By the way the only thing I remember is that I have upgraded a few months through OTA, and I needed to get a newer RUU. Not sure if the hboot got upgraded or not.

I only have one idea to turn it off is to throw it to water. -.-
Maybe it is more defective than we thought. Try pressing the power button really long and or.press volume up to enter fastboot. Otherwise just send it in, if it constantly reboots the Tec guys can't to much, too.

Unable to get into bootloader or recovery mode, stuck at white HTC logo screen

Hey everyone,
I have read the various topics with a similar title but none helped.
Here is my problem, I bought a used HTC Desire on eBay. It booted just fine on the first start, then I did a factory reset (from within the Android system menu).
Since then, I'm stuck at the white screen with the green HTC logo. I have tried to get into bootloader mode by removing the battery, holding vol down and power, but it just goes straight to the white screen again.
Also connected the phone to the pc, but adb isn't picking up anything...
Any ideas?
Try Power+Back button.
just got one step further:
I can get into fastboot mode with BACK + POWER. But volume keys doesn't work, is that a known issue that I can solve somehow?

Then you'll have to flash a RUU to make it work.

It's official HTC Firmware. Your phone will boot after this.
So:
1. Install HTC Sync.
2. Download and extract the RUU.exe from the zip (It's somewhere in there)
3. Run the exe while you connect your phone in fastboot (Power+Back)
4. Wait for it to install
5. Boot

Weird.
This may be the reason:
Now, that may not sound too bad to some of you, but there's more: the 2.3 RUU update is limited regionally, as well. It's not available to users in Germany, North America, South America, South Korea, or Japan.

wtf... tried again flashing the 2.3 RUU, this time it worked, YEAY
But now I have a bootloop, device starts, vibrates 1 time, waits for 3 seconds, and then vibrates 7 times. And restarts...
Ok. Tests are done.
According to the screenshot above and the 7 vibrations, you have a radio brick. It's a brick that can hardly be overcome.
The only solution is flashing the RUU and hoping that the phone will eventually boot.
That's why I don't buy second hand phones.

freecer did it, was able to flash the 2.3 RUU again successfully. But now I'm back at the bootloop, but now, it simply does vibrate once (no more 7 vibrations) and reboots after some seconds.
So what can I do now? RUU flashed successfully, I'm running out of ideas...
and again the freezer did it, put it in, normally started via POWER button, it booted right through into Android.
Well, let's see if it keeps running now or if this overheating issue also exists in normal operation mode...
Thanks so much for you help so far, the freezer hint saved this device and hopefully will make my gf very happy tomorrow
Hold on I thought it was some pvt1 devices that had overheating issues.
Thought it was fixed on your newer ones. Then again I've never had a problem with my pvt1 desire flashed both hboot and find countless times.

it is a PCT3 device.
but the overheating-reboot issue is rendering it useless. I can use it just fine outside (-2° currently) but as soon as I'm inside, boot-loop...
Anything I can do from a hardware perspective to fix that? Sending it in for repair/replacement is not an option, it's simply not worth the cost.
do you think installing a custom rom of any kind might help?

It's a motherboard fault. If you don't send it to repair, you just got yourself an "Ice-Phone", or a very complex paper holder.
i think a custom rom would help a small bit, like the rom in abaaaabbbb63 sig (mildwild redux) because its small and lite unlike a sense rom. therefor it mite not overheat as quick or as often. but thats only a guess. the only dodgy thing is trying to get ur phone s-off or rooted because if ur phone overheats in the middle of the s-off/rooting progress u could brick ur phone. plus charge ur phone using ur computer coz it uses less power and the phone does'nt heat up as much as plugging into the wall.

HTC Desire HD won't boot.. help!

Ok guys, I definitively need your help now.
This morning I woke up, i toke my phone (already on) and I saw that keyboard didn't work anymore, so I rebooted it and appeared the white screen with HTC LOGO, then three or four vibrations and BUM... FREEZED.
The phone is rooted, with custom rom. S-OFF.
The problem is that i can't enter into RECOVERY of the phone anymore, but I can still enter into BOOTLOADER. I tried to do a FACTORY RESET, but doesn't work (the display show again the htc logo with some vibrations before the freeze).
There is some way to format/repair with the help of PC ? Like when i changed my RADIO some weeks ago... or.. I don't know.
Thanks.

That sounds like a fried motherboard. Try flashing a RUU from fastboot usb. If after the flashing the phone keeps not booting, then your motherboard needs to be replaced.
If you need help with the flashing read the guide in my signature to find out how to perform that stuff. :victory:

Check or volume rocker/keys. On the mytouch 4g, when u press volume up and power key while phone is off, it vibrates and the notification light blinks red. So maybe or volume up key is stuck.

M9 maybe total brick after stock flash

My htc m9 upgraded to 6.0 i tried to downgrade with official
5.0 the flashing process went faster than usual
It asked me to reboot and it never came back to live
No charging led nothing and my pc does not even feel it when
I connect it
Please i appreciate any help thx
Not sure if tried or not.... Have you tried simply holding down Power and both volume keys to force a restart? Seems odd that it would brick the phone.
Normally when an RUU sees that your phone has a newer software it would just fail and the phone would be fine. Unless you're S-OFF in which case it would flash it anyways.
We need more details.
1. Did it successfully upgrade to 6.0 and you had no issues prior to trying to downgrade?
2. How did you try flashing it? Was it the RUU wizard on Windows, or the rom.zip via a command prompt/terminal

Can you boot to the bootloader from power off state (POWER+VOLDOWN)? If so, hope is not lost.

I suspect you are hardbricked (why on earth did you downgrade?) but it's possible the flash got confused somehow. Try holding down all three buttons while the phone is plugged in for at least minute. If that does nothing, leave it plugged in overnight and try it again. If it's still dead, you have a brick. Next time, be more careful about flashing random stuff you find via Google.

Not sure if tried or not.... Have you tried simply holding down Power and both volume keys to force a restart? Seems odd that it would brick the phone.
Normally when an RUU sees that your phone has a newer software it would just fail and the phone would be fine. Unless you're S-OFF in which case it would flash it anyways.
We need more details.
1. Did it successfully upgrade to 6.0 and you had no issues prior to trying to downgrade?
2. How did you try flashing it? Was it the RUU wizard on Windows, or the rom.zip via a command prompt/terminal

What type of M9 do you have? Is it a generic GSM model or something else?"
If it's generic, you may have gotten a corrupted download. Did you check the MD5 before flashing?

The exact same file?
Downgrading can be tricky. It doesn't always work exactly right. If your phone is still dead after this, something went wrong with the flash. It can happen.
Sounds like a bad flash. Double check file sizes and md5 hashcheck to be sure the rom was complete.
If the phone won't even show any sign of life you may as well call it dead. If you live in USA you could try the uh-oh policy that htc implemented. They promise to replace the device one time only no questions asked.
