Hey guys

I was super happy with my Australian Telstra M9 until an hour ago. I plugged it with 3% of battery in for charging and turned it off to speed the process up. When it was off the charging icon showed up just as usual. After a few hours I came back, unplugged the phone and it flashed 100% for a second. After that - nothing! It just won't turn on! I pressed every button and every possible combination of those. I plugged it back in for a bit and connected it to my laptop. But it's not even recognized. I googled for a bit but found no solution. I rooted the phone a couple of weeks ago but didn't do anything like that today. No updates, no new apps only some WhatsApp and 9gag.
What do you reckon? Is it bricked? Will I get a replacement and how long will that take? I have to leave Australia in 9 days so I'm quite on a schedule. -.-

Does anyone have any advice?!

Cheers Max

Edit: is there a chance to recover the data? I'm traveling and forgot to back anything up. Some of the data is quite important. And do you think I'll get into trouble because of the root?

I tried three different charges plus my laptop. Neither of them worked. Is there gonna be any way to rescue the data from the internal storage or will the just wipe it after they repaired it?

I would try holding the power and volume up button for at least 2-3 minutes. If it does come on, as soon as you feel it vibrate, move your finger down to the volume down button and hold it until you get into download mode. Then boot to the bootloader and then recovery and restore a nandroid.

Oh my god!!! Thank you so much! I have no idea why but after a minute it booted up just fine an all my data are still there. I'm never ever gonna forget a backup anymore. But what happend? Why did it start again? Battery is down to 50% so it seems it has been running all night and was stuck at some point. What can I do to avoid this from happening again? I don't wanna get a heart attack every time the phone won't turn on :D

But for the moment I'm alright! Thank you, thank you, thank you!

Hold power + volume up button will work in most cases.
TBH, don't really know what happened to you. Did you flash custom rom, recovery? or only root? :confused:

I didn't know that. I only new power + vol down. And I didn't hold it for a minute. I did nothing but flashing TWRP and root the stock rom. I didn't even change much with the root and only use it for titanium backup and adaway. That's why I was so baffled, when the phone suddenly "broke" because I didn't do anything unusual to it.

I'm glad you got your phone up and running. I know exactly how you feel, I had the same thing happen to me. I thought mine died when the screen went black after I flashed a kernel. Its always scary when the phone won't respond.

The phone was likely frozen. Power + Volume Up forces the phone to reboot after being held for a while. It could be some weird software issue due to the rooting and TWRP, but no one can say for sure. It might happen again but now you know how to reboot it :) If you really want to avoid the possibility of problems, you probably want to run stock and not root the phone or change bootloader... but what's the fun in that?

You're right :D no risk no fun. I'm actually waiting for cm so running stock is no option anyway :D

Thanks for saving me lots of headaches

FYI - I thought I had bricked mine as well - no flashing activity in a couple of weeks, all good chargers. Even made an appointment for repair.

Read the "hold power and vol up for a minute or two," and was like... nooooo... 10 seconds is the max you'd do that for... but tried it... bam, worked like a charm at ~45 seconds for me. Got into HTC FTM mode in which no option worked (reboot to bootloader, simlock, couple of others seemed to just pop immediately back to this weird non-download menu). Holding power for a while after that reset the device. Working now.

Thanks for the thread... been doing this for five years and this is the first no-charge no-response event I've had

Hi All,
About a week ago my M9 powered down while on charge and then wouldn't power on again. No response at all from the standard power button but only holding it for a few seconds at a time.

I knew the buttons to hold to enter bootloader and after several tries it powered on again.... It then ran for a couple of days with no issues.

Then a couple of days later had to power off the phone on a flight - same issue - wouldn't power on - dead.

It took several attempts to bring it back to life. I'm now in a position when every time I power off the phone it just doesn't want to come back on? Thought that it may have been a custom rom issue or a kernel issue - have tried changing both (painful experience by the way - having to wait for the phone to decide when its ready to wake up "when it feels like it after each new installation) but the problem is still there.

I have also found that entering bootloader using the power button and volume button isn't the only solution to "waking up" the phone. Just holding the power button for 10-60 seconds has the same effect - but it sometimes takes several attempts over several minutes - its very random.

Does anyone else have this recurring problem every time they power off? Does anyone on "stock" have the problem?

I'm starting to think that maybe its hardware rather than a software issue?

Try turning off the phone, plugging in the charger, and holding all three buttons for two minutes.

HTC has recommended this as a fix for battery issues like the slow charging bug. Apparently it clears all the battery settings and recalibrates it. The phone will reboot repeatedly while you're doing this, but that's normal. Keep holding the buttons.

I have seen HTC phones do this in the past when the battery system gets confused.

Bricked M9

My M9 is not quite 6 months old - ALL stock. Went to bed last night , M9 quick charger plugged in with green light and phone power on - just in airplane mode. Woke up 4 hours later and found the phone dead.

I tried 1 button, 2 button, and 3 button holds for 5 minutes each, plugged in and not plugged in - still dead!

Any help would be appreciated.

Best to run a logger like BetterBatteryStatsor GSam Battery Monitor to find out what is draining it

I am unaware of any way to do this if the phone wont turn on - it's dead.

Ah you cannot even get it charged anymore?
I know HTC phones had an issue that when they are completely drained, they seem to be dead, even not charging or anything. Yet if you keep them in the charger, eventually they would show as charging and being able to turn on again.

Leave it in connected to the stock charger overnight and see if that helps. If not, you might have a hardware fault and need to return it for warranty service.
