[Q] My T989 wont turn on

Never seen or heard about anything like this. I wonder if anyone encountered a similar situation.
I have a good reason to believe my phone is not bricked, although I'm not sure which is worse.
I'm not sure if it's related, but it might be worth mentioning here:
I noticed, since I started using this phone, that the battery level sometimes drops very fast. Normally the phone maintains normal battery level, but while opening "heavy" applications (e.g waze, google earth) or even during a phone call, It drains the battery out rapidly, roughly about one percent per two minutes. Sometimes even while connected to charger the phone shows a slight decrease in battery level. And it gets hot too.
Few hours ago, I turned it off to save some battery for afterwards, and since that moment it wont turn on. I tried several things.
I left it to charge.
I took the battery out and placed it back after a while.
I tried all possible combinations of the three physical buttons on the device.
I took out the sim card and the sd card.
At home I checked the battery, It shows normal voltage of 4.1V. I used several usb cables and measured the voltage between the battery connector inside the phone while the battery is removed. It indicates that the phone keeps charging the battery even while staying in this situation.
While plugging it to the computer, the phone is not even identified by it. It wont react to the computer just as if it's not connected at all.
Getting it to usb mode showed no result.
I have installed new roms on the device several times, yet more than a week has passed since the last time, and the phone worked fine since. except for the battery issue that I mentioned.
It was originally bought from T-mobile without contract, and it has a warranty assuming I would be able to bring it back to stock rom. Anyway, I'm using this phone in Israel and the nearest T-mobile service point is 10,000Km away, so I would do this as a last resort.
Hope for some advice, and may this post be able to help others that got in to similar situation.

Have you tried getting it into download mode? Disconnect from the PC, then keep both volume buttons + power button pressed while connecting the USB cable to the PC.

Phone won't turn on
Just had this same experience. I had just taken mine off the charger in the morning, booted it up and minutes later, it restarted on its own. Never came back to life. No possible combination of buttons, batteries, usb cables, ODIN running/not running would bring my phone to life. I mean I tried everything including the famous usb jig. Nothing. Sent it in to TMo and as it was within 30 days, they sent a new one which is running fine.

The problem is...
The phone is not recognized by any device, while being connected to usb. The only thing it does while plugged is to charge the battery, and that I can tell by measuring the voltage. It gives no visual indication, or respond to any button\connected device. Using that jig is the only thing I got left to do. I know it suppose to reset the counter. What else will it restart? My rom?, internal sd? the recovery partition? Can this physically damage the components on the phone's PCB?
And assuming the phone hardware is unharmed, are there any firmware malfunctions which are impossible to repair? (Generally I know there are, yet I'm asking specifically for these phones that comes with "download mode")

Had a situation where the device wouldn't turn on. Woke up one morning and it was still on the charger yet totally unresponsive.
Pulled the battery, waited 30 seconds and everything was fine.

I wish it was that way for me too, yet it was one of the first things I tried. and yet, Nada. Here are some news: I gave the jig a try, and it didn't seem to work either.
On contrary to most of the fully bricked cases I heard about, my phone wont be recognized by the pc at all while being connected to usb. Not even a "Faild to connect" message. That leads me to believe that it is either a dead Boot-loader or a hardware malfunction.
I made a little research, and found out that it is possible to connect the pc through some kind of adapter directly to phone's processor, using specific pins. It is a simple kind of serial connection called Jtag. Initial factory configuration of electronic devices is only one application of it.
For that process I need to have that device along with it's driver, a boot loader to flash (According to what I've seen the T989 is not yet supported by these softwares).
I need to have some nerves to open up my device and to solder some pins (And I also need that Jtag pinout).
Does anyone know about a better way of doing it other than sending the phone half world to the U.S?

[Q] sponteneously bricked EVO-4g

I have a rooted HTC evo 4g. I rooted it about 2 months ago and have had no problems.
I woke up this morning, and it is bricked. I have not recently flashed anything or done anything beyond regular phone use.
i cannot enter download mode, and the "charging" led does not come on.
Any suggestions?

What does your phone do when you press the power button?
Have you removed the battery and inspected for indications of damage such as discoloration or bulges?
Have you tried connecting a different USB cable that is known to be working?
Have you visually inspected the USB connector for loose/damaged conductors?

the power button does nothing.
The usb cable and wall adapter works on my kindle, and i tried an additional one with no results.
The battery appears normal, however my next planned step is to try and get a replacement battery and see if that works.

Try taking battery out and then plug usb cable in only and try to turn on...

no dice.
also wondering about the cause... 2 potential things:
- I've noticed that the phone gets very hot. 40+ degrees even when not running much. Is this within normal tolerance or could i be looking at heat damage.
- I've been getting the pop-up asking me to do some sort of OTA update. I keep saying no, because i know these ota updates can be incompatible with rooted phones. Could it have pushed through somehow and if it did could it cause the problem i am experiencing?

phone is fixed.
A read on the sprint forum that sometimes holding down the power for an extended time can get the phone to be responsive... had to hold it for like 90 seconds. It then flashed the white evo boot screen and powered back down almost immediately.
After this, however, the orange charging light came on and i was able to get to boot loader. I let the phone charge for a while, then it boot up as normal.
One of the things i noticed is that the battery is practically completely drained... this is odd as it was plugged into the charger when it died. On the same sprint forum, others have speculated that sometimes the battery can drain to the point where it wont accept a charge anymore... so maybe thats the issue.

[SOLVED] [Q] Possibly bricked....

Hi,
my battery ran very low (~2%), and I put it in a car charger, and used it for a call. I've heard of car chargers or combination of different cables etc. causing problems, but I think I can rule out a burned out motherboard, as the phone was functioning for the call and a text was sent after.
About 5 min after I took it out of the car charger (got home) I noticed that the capacitive buttons were lit. I tried turning the phone screen on, nothing happened. So I held down the power button for 20 seconds or so, again nothing. Then I held down the power button and volume down, and it went into recovery (twrp)
Not sure why I did this, but I wiped the cache and dalvik cache, and hit reboot system. Now at this point I don't know if the battery died, or if it tried to reboot and didn't work. Either way, it is now dead
I have tried the following;
Hold power button, no response
Hold power button, and volume down, no response
Hold power button, volume down and volume up, no response
Left charger plugged in for an hour, no response
There is no led light on when the charger is plugged in
I have tried connecting to a pc, it makes the 'new device connected' sound, and soon after, the disconnect sound. Windows states that the usb device is not recognised.
Any ideas?

Forgot to mention I'm on Slimrom 4.2.2 build 8 official
Is it true that the phone can't be charged while in TWRP?
Any help would be appreciated, I need to flash KK!!

Shameless bump
I have tried the script to get the phone to charge/ get battery voltage here;
http://www.hackmyandroid.com/comprehensive-guide-on-unbricking-the-htc-one-x/4216
Also, I have read that there could be a script to get the phone to charge, post #4 here mentions that;
http://forums.androidcentral.com/htc-one-x/300271-htc-one-x-will-not-turn.html
Can anyone pls help with this script mentioned in post #4??
I've rooted/ custom rom'd about 9 phones, I can't believe that it can be bricked by losing battery power while in recovery... nothing has ever gone wrong like this, please help!!

Try leaving it charging for ~24 hours

Try unplugging the battery from the motherboard and plugging it back in, if not get a new battery HOX is only about 5 pounds or you can upgrade to a HOX+ battery for about 20 pounds.

tried charging overnight ~12 hrs, no joy, but thanks
I have it opened up now, so might try disonnecting and re-connecting battery, thanks
I have been speaking to the team at TWRP on irc chat. Somebody suggested to strip USB cable back and connect bare wires to terminals of battery to see if it will charge. Will this cause problems as USB is ~5v and the battery is 3.7v??

I wouldn't risk the USB thing. You might as well get a new battery. I have a spare HOX+ battery which is 2040mah bigger than the HOX, I could sell that to you for a cheaper price than everyone elses.

I have since replaced the battery, and also a new power flex cable (that I broke during disassembly!) and something has changed at least......
Beforehand, Windows did not recognise the device at all, sometimes the 'USB device not recognised' dialogue box wouldn't even appear, although it would make a sound
Anyway, now it says that it's not recognised, but in Device Manager, it says it is a APX device (before it was an unknown device)
Can anyone shed any light on this?

HTC M8 Doesn't Boot, Red LED Flashing, Not Charging

HTC M8 doesn't boot red LED flashing not charging
Hi,
I have big problems with my HTC M8. It is 11 month old.
I is rooted, has 4.16.401.10 firmware, Android Revolution HD 43.0 and
S-off SunShine.
In the evening I put it on the charger with 61% battery left. The next morning it didn't start up anymore and the red LED was flashing.
The battery didn't charge and so long it doesn't boot up at all, I can't connect it to the PC. It is only shows the big battery sign when I connect it to the charger which disappears some seconds later.
I didn't want to send it to HTC for guarantee, because I couldn't put on stock software.
My lokal handy-doctor changed the battery... nothing!
He changed the USB connection... nothing.
The red LED keeps flashing, the battery doesn't charge, it only becomes warm, I cannot turn it on. I have tried to press the power-volume+ -volume- buttons, nothing.
I think HTC will charge me, if I sent it for guarantee, or does anyone have other experience?
What should I do? Any idea?

Try holding the power and vol up for a long time, maybe a minute or so, and see if there is any change.

That was one of the first things which I tried. It has no effect.

Try power+vol up, and also power+vol down, with and without wall charger connected. I've seen a couple people have luck with that. Otherwise, if it still won't work, its pretty much bricked.
Especially since you've already had a new battery installed, it may be a problem on the mainboard.

Since you've had a 3rd party take apart the phone, replace the battery, and replace the USB port, your warranty is void.

I did that so many times. It doesn't help. I think its a hardware problem.

As you tried all the things I suggested with no luck, I agree its probably a hardware problem.
This would have been justifiably covered under warranty, since its a hardware problem. And since the screen doesn't come on, they wouldn't have known it was ever bootloader unlocked, custom ROM, etc.
But now that you've had a repair shop open it, it will be obvious to HTC the phone has been opened and they will probably charge you for repair.

From what I'm seeing, the M8 is only eligible if purchased after March, 2015 (which the OP did not):

This isn't the "same problem" unless you (like the OP) took it to a repair shop, had them replace the battery and then the USB port? I doubt it.
Posting "I have the same problem" is just lazy, and doesn't give us the proper info for anyone to properly help.
How did this condition come about, did you just find the phone in this condition? Or were you flashing anything or any other actions to cause this condition?
Plug the wall charger (not connected to computer) overnight. Then hold the power and vol up buttons for a minute or 2, and see if there is any change.
Also try a different charger and cable.

Ok, sorry for the lazy answer.
So, yesterday the phone works fine, when i go to sleep.
Today, the alarm clock sounds, I woke up, and when i take the phone, the screen is black. Therefore, it didn't work.
I used another charger and cables, but don't work.
The S.O is sense stock, only had custom recovery, but I never used.
If i plug it to the computer, isn't recognized.
Maybe, you can know any solution for that?
A lot of times, I try, with power + vol up and power + vol down, for around 20 seconds.

Thanks for all help, but my phone didn't change the red flashing.
I think I have to accept that my phone died the red flashing death. RIP

I specifically said to hold power + vol up for 1 to 2 minutes. 20 seconds isn't enough in some conditions.

Nothing shows up in Device Manager (if you are using PC)? Such as with an exclamation point by it?
No message about Qualcomm drivers?

I try again yesterday, hold the 3 buttons of 1-2 minutes. After that, hold power and vol + for the same time and any signals.
If i use my PC, doesn't recognize, didn't install drivers, or something else.

Flashing "M" screen and only powers on when connected to the computer via USB

Flashing "M" screen and only powers on when connected to the computer via USB
Howdy...not new to the forums, but new to this forum as a member. I searched for this many times but never really found an answer that works for me.
So that being said...here we go...
I have a 360 1st Gen. I have the a usb cable (that I made) and have unlocked the boot loader, factory reset it, installed all the drivers, yada yada.
My issue is that when the 360 is connected to the USB cable (to my computer) it powers on and loads just fine and the watch is fully functional, even with my
iPhone, but as soon as I disconnect the USB cable it turns off. If I put it on the charger it just flashes the "M" screen and vibrates every 2 seconds. If I put it back on the
USB cable, it powers up and is fully functional again and everything is saved and reconnects to my phone. disconnect the USB, and power off instantly.
Any one know what the issue is? If so, can it be fixed with RootJunkies Super Tool?
Thanks

Someone has had to have this problem before...
I'm thinking it might be a battery connection problem. I guess I'll take the watch apart.

i can surely say ,this is battery problem..
open ur watch (take apart)
check ur battery connection
if needed u have to replace battery..
i had opened 360 , without battery and usb connected this is fully functional.. so just check ur battery

Have you solved the issue? I have exact same problem.

Yeah these are classic symptoms of a dead battery. You will need to replace it.
eBay usually has some of the official batteries on there, swapping requires a complete disassembly, some soldering and some fine work to put it all back together. Its about a 30 minute job if you know what you are doing.
