[Q] MT4g Not Booting - myTouch 4G Q&A, Help & Troubleshooting

My MyTouch 4G powered off one day and won't power on anymore. I've tried pressing the volume down and powering up at the same time, but no response from that. I've checked and made sure that the buttons are fully functional. When I plug the phone in to charge it or to connect it to the computer, the back, Flash LED lights up. Help please?
I've tried looking for other posts and seeing if anyone has had problems like I'm having and there seems to be no one else. Thats why I'm making this post. Anyone know how I might be able to fix this?
The phone was running the stock MT4G OS. I tried establishing adb connection but nothing happened.
Thank You!

Your power button might be dead.

Or you have a brick

So, the phone's dead now? There's nothing I can do about it?

Connect to charger, then put the battery in.
Try several time.
If it's power button failure - this might bring it to life.
If not - there's nothing you can do, give it to someone to fix.

Broken Power Button

My power button has been acting funky lately, i thought it was just a software issue until i switched my battery today and realized it was hardware. now i cant turn on the phone.
Is there anyway to power on the phone via fastboot or some usb command? i need to get some files off the device before the device swap but i dont know how to turn it on without the power button =[
any ideas?

One of the bloggers on Droiddog.com had the EXACT same question. Yes it's possible... read her method here:
http://www.droiddog.com/android-blog/2010/06/nexus-one-power-button-failure/
Basically:
Plug the phone in– USB or AC works fine.
Wait until the charging light comes on.
Remove the battery, while leaving the phone plugged in.
Replace the battery.
After about 3-4 times, the phone should boot.
i need to know if i can turn it on via usb command, ive already called in for the device swap.

it worked!!!!!!! fourth time it started right up. thank you so much you saved my life
if you take it out and wait till right after the charging light goes off then put it back in it seems to start up a couple seconds later!
Glad you got it up and running. Sorry I misunderstood the question.

NAND Phone-Off Charge Issue - *WORKAROUND*

I've been having this problem since the first installation of MAGLDR; The "Orange LED" bug, as most of us know, prevents the phone from charging while the phone is off, and the LED remains orange even AFTER the phone is unplugged. I've found a few circumstances where this will occur:
1. Powering down the phone with USB plugged in causes this issue with most builds
2. Same as #1 but when doing a reboot
3. Phone dies, then plugging USB will bring about the "orange LED" bug
I've found a workaround for these as I'm sure MANY of you have already, but I wanted to post a thread just for people who haven't found an answer yet. The following list corresponds to the items above:
1. Unplug USB before selecting "Power off" on your device
2. " " " " "
3. Kinda tricky.. a) if phone is COMPLETELY dead, pull the battery, plug USB, THEN replace battery, and b) If phone has battery and is OFF, power on phone, wait until "GO! GO! GO!" screen disappears, and then plug in USB.
I think the problem comes about when finishing the installation of your ROM via MAGLDR, OR it could be a bug within MAGLDR itself. It could quite possibly be the kernels, as JDMS' UltimateDroid ROM did NOT cause the orange LED when a REBOOT was performed...
Well either way, I hope this helps some people avoid this problem and gives the dev's something to work on.. Not that their work goes unappreciated
Or do like me. Leave the phone on, put it in flightmode and charge it.

How would this help if phone is completely dead? Seriously, this could be useful. Can someone try this and confirm?

I'm afraid to answer here as the OP might get upset, or tell me to start my own new thread.
Anyway. As I like to help people I will answer your question.
I bought a new battery for my HD2, and it did not have enought power to power on the phone (running NAND).
Not sure if this fixed the charging problem, but I removed the battery for +/- 30 seconds, reinserted the "dead" battery, plugged in the charger.
After some time (seconds) the orange battery came on, and the battery was beeing charged.
I left the phone charging for some time (expecting the light to go green when done), but it never did (NANDproblem?)
So after 1/2 day of charging, I disconnected the charger, and guess what.. the oragne light was still on.
Again I removed the battery, reinserted it again, and powerd on the phone.
The battery was fully charged, and I'm now enjoying 2 to 3 days of phone use before needing to charge it again.
Now.. I'm not 100% sure about 1st connecting the charger, and reinsering the battery, or 1st reinsering the battery and than connecting it to the charger.
I'm having charging issues but in a different way.
when i plug the charger to the phone while the screen is off, the LED does not light until I i press the red button (actually any button) to wake up the screen.
Is anybody having a similar issue?

This is not a problem for me too. The real problem is with whatsapp
when ever someone sends me a message on whatsapp while the screen is off, i dont receive it until i press the power button to unlock the screen. So i thought this might have anything to do with the charge issue.
I have no problem with this bug,he it is on the charger,so why turn it off is my question.....i just turn the sound off lol.

[Q] mt4g flashing LED no vibrate no screen

Hey guys, Im trying to fix this mt4g for a friend.. It wont boot, I cant get into hboot or recovery, all it does is flash the LED. I have read post saying its because I was unsuccessful at loading bootloader, however it doesn't vibrate like the others are saying. I left the battery out for a couple hours along with sd and sim, also tried charging through the night... I cannot figure this one out, also, the computer will not recognize any new hardware or drivers. Is this phone bricked beyond repair?
I put the battery on my battery charger and let the battery charge outside of the phone now when I put the battery in the phone and plug it in to the computer, the red LED comes on and stays on, along with a red glow on the trackpad... Anyone know what to do?
Blinking LED is either the battery is charging to at least one percent, or you didn't press the right button combo to boot into bootloader. Power + Volume Down is bootloader, Volume up will give you three vibrates and a flashing LED, where you will have to pull your battery.
Thanks, I cant get the phone to do anything... I plug it in with the battery in, without pushing any buttons and the LED comes on and the IR trackpad light comes on... It wont respond to anything, no drivers popup.. Is there anyway to recover a bricked mt4g? Im new to it, as I have an Evo and have never had anything like this occur with all the evos i've flashed and rooted... If someone knows anyway to fix this feel free to give input..
Thanks everyone!
ya .. mine is doing the samething.
I just try to turn it on and I get one vibrate ... nothing else
I hit down and power and I get one vibrate .. nothing else
I hit up and power I get 3 fast vibrates and a flashing orange led ... I try to plug the USB here and I get 3 fast beeps on the comp
I hit up and down vol and power I get 5 fast vibrates with a solid green led and noting else... usb again beeps 3 times on the comp
neither will recognize the usb and I have reinstalled the drivers .. and of course none will work with adb either.
I think we are screwed really ... but maybe someone knows something i dont on this here. Thanks for any help.
if you fix your phone. let me know

ya .. no luck so far ..I have tried a lot .. different drivers .. HTC sync .. etc.
I have tried different button pushes .. usb ports .. wont work in adb .. nothing is doing anything.
all I hear thru my speakers when I plug it in is that damn the fast 3 beeps .. ike a "hell no go F yourself you arent connecting it"
and there isnt a lot of info online bout this .. other than some others have the same LED blinking and stuff .. I still dont know what the different LED modes mean.
so IM screwed .. BUT I am getting an LG G2X as an alternate exchange thru T-Mobile warranty though. goodbye mytouch 4G Hello to G2X AND Galaxy S II(bought) .. fun times!
I found a thread somewhere, not sure where but it said that if you cant get anything and the infra-red on the touch sensor is lit the phone is completely bricked!
Its not bricked. Somethign is wacky with the phone, mine has done it and thats why im trying to find out what the hell is going on. My phone acts like its completely dead. This post migt end up being really long.
Ok, i notices this, i used my phone as a wifi hot spot. Turned it off. Left my phone alone, i then put it on charge and went to sleep. Woke up looked at the battery, no color other than the lighting bolt. Unplugged it then went off. Pluged charger back in and orange led flashes. Tried to get into recovery nothing. Tried to power it on, nothing, tried the volume down and power, three vibrations. Ok then i decided to take out the battery in and out, didnt work, tried leaving the battery out for a few minutes, then put it back in, same. Took out memory card, sim card. Then plugged in the charger. Let it sit for awhile then it works. I notice if you dont use the orginal charger that may also be the problem. I dont have my orginal but i used a walmart charger and seems like a super charger and some how charged my battery enough to be booted up, i daily use a charger that i found with the same connection x-( , that could be the problem. I dunno what makes this happen but it happened to me at least three times. I kinda figure the battery or the emmc chip is involved, could be the hotspot, could be anything, but we dont have enough evidence to figure it out, ill try to post what my battery usage on here. I use cm7 and it only happens when i use it. I tried all other roms but no repeats. That was my story.

I have done all these as well, and still unable to get past the black screen, or acheive bootloader as well. I have even left the battery out for a couple of hours, and still no different. Going to try recharging the battery once more, and some other things.
As for adb it is of no help as of now. I keep getting an error saying no device found. Has anyone found a way past this yet, to try rebooting through adb?
*Edit*
After trying to replace files on the sdcard I was not able to get past this issue. Also spoke with tech support, and was not able to get anywhere with their help. After speaking with them, I have come to conclusion the is bricked. I still cannot figure out what caused the phone to do this I broke down and sending it out to be replaced. Thankfully I have the insurance so I don't have to pay anything for the replacement.
Apparently its not bricked cause I'm still using mine. Try a different charger probly a stronger one like walmarts. I think the battery has a fart and is messed up for a little when it doesn't have a good charge

I have done this, fully charged it twice, and no change for me. I am glad it worked out for you.
Its not bricked.
Download the stock rom, and put that .zip in the root of your SD card. Put it in, press Power + Volume DOWN and wait for the bootloader. Once it boots, it should recognize the .zip and ask if you want to update it, run the update and your phone will be at stock again. Then root again, install Clockwork, and hopefully you backed up your ROM. This won't effect S-OFF, but you will have to run VisionARY again to get root permissions to run clockwork.
Hope this Helps.

I am too having this problem
just blink orange
can't access bootloader or any else....
I too had this problem not too long ago. My power button wouldn't work though... I just connected via USB to my computer with the battery out, put it back in while connected and it turned on. Maybe I'm just lucky but give it a try

[Q] Nexus 7 wont turn on!!! Making a very small buzzing sound.

Ever since 2 days ago, my Nexus 7 has not been able to turn on. I have tried holding the volume down button and the power button multiple times, tried that while plugging it in, tried it after waiting for several hours of it being plugged in, and even popped off the back cover to unplug and replug the battery. I tried holding the power button for more then a minute. I have tried everything. One thing I did notice when I took the back cover off is when the battery is plugged in, I can hear a vary faint buzzing sound that appears to be coming from the top of the tablet above the battery area. Not sure what it could be. Wondering if anyone has any recommendations to help me? Thanks!
Bump.

It might help if you could provide more details...
---------------------
Such as...
Prior to your current predicament.... did the device just crash? ... or was it simply dead from power on?
What was the battery charge level? (If you can remember).
Were you rooted? Running a custom ROM? ...or stock?
Have you flashed any custom kernels? ...and if so, which?
What happens when you plug in the charger? What do you see?
What happens when you connect the N7 to your computer?
Have you tried booting into the BOOTLOADER (cf. http://forum.xda-developers.com/showthread.php?t=2133986).
---------------------
The more details you can provide, the more likely somebody will be able to offer a diagnosis, and hopefully a solution.
Rgrds,
Ged.
Last time I checked was the battery was reading 51%. It was during a sleep mode and I tried to wake it up again. I am unlocked and rooted. ParanoidAndroid 3.16 and FrancoKernel r60. I have tried all key combinations with the buttons to get it to turn on. Nothing shows on the screen. Not a flicker. Nothing happens when I plug it in. Loading into the bootloader, nothing happens. The only thing I notice is when it gets power (from either the battery or the charger), a small buzzing sound comes from the top area above the battery. That is it. Tried re-setting the battery connector with no success. Charger does not help in any form. Thank you!

I actually used your forum first before I looked into other possibilities. Unfortunately, the issue still persists. I feel this one is out for the count. DEAD!!! haha too bad. I really liked it!
Sorry to hear that. Since you followed all of my recommendations, chances are your N7 really needs to be returned. Bummer.
maybe need to be returned

Nexus 7 won't turn on

It seems there are already several threads about this seemingly common issue with this tablet, but I've tried the normal checks and still can't get any life out of my dad's nexus 7 whatsoever.
I've found several threads stating it's just a loose battery, but in this case it isn't. I've checked absolutely every single connection I can get to without removing the void if removed bits, and can't find anything suspect. However it still won't turn on, won't charge, etc. It's not a faulty charger or cable either, we've all got android in my immediate family and we can't get any life out of it with any lead or charger. It was simply working one day, it was turned off the way it always is once my dad had finished using it, and now it simply won't come back on again.
I also saw some people say to get it into bootloader mode by holding volume down and power straight after plugging it in, but that too does nothing whatsoever?
Does anyone know of anything else I can try, short of sending it back to Asus?
How long have you had it?
This sounds like something that should be addressed as a warranty situation, as anything else may be kludgy at best, and may fail again just after your warranty runs out.
I wouldn't really waste any more time.
JMnsHO.... :beer:
My dad has had it about half a year, maybe a little more. But he bought it from Comet, who no longer exist since they went under just after Christmas, so he can't return it to them now. Unless it'd just go straight to Asus instead.
I had exactly the same issue.......I fixed it by disconnecting the battery and reconnecting which by the sound of your post you have already tried.......you should be able to go straight to Asus for repair.......good luck....
Sent from my Evo 3D GSM using xda app-developers app
After probably 30 days it would need to go back to ASUS anyway.
As I'd said, I wouldn't waste more time fussing with it.
They'll take care of it and still preserve the balance of the warranty.
If you messed with it too much, you may find yourself with none at all, and on the hook for the cost of the repair.
Make the call.. :thumbup:
Well I've not done anything that shows I've been in there like I say, so any manufacturer warranty should still be intact. Same goes for the software too, not rooted, on the standard rom and kernel, etc.
I was just hoping I could fix it for my dad without having to send it off.
Not yet, but anything else would be more 'intrusive'.
How long have you been working on it?
Not long, only 10 minutes here or there to see if I could find something loose. I might check the voltage of it's battery to see if it's flat, and also check to see if any power is getting to the battery while charging. That'll help prove if the battery or it's control board is dead or not.
Just checked the battery over. It's a 3.7v battery according to the label, and my multimeter shows 3.7v, so the battery is fine with no loose connections. At the connector for the power button ribbon cable, I get the 1.8v that should trigger the tablet to power up when the power button is pressed, and the power button is good too, only showing continuity when pressed. Again, no loose connections. But the bloody thing still won't turn on.
Any more ideas?
When you say that you "tried all the normal checks", does that include all of the fixes listed in the sticky dedicated to this subject?

Yes, your thread is about a faulty or loose battery. As I've said, it's not a loose connection and I've now tested the battery too. Unless you can think of something that I've missed?

That sticky has all of the well-researched methods of addressing the collection of related issues (won't turn on/won't turn off/battery status). It is not only about a faulty or loose battery - there's much more.
Give it a read and let me know if there's a fix in there for you.

If your able to get to bootloader maybe try to power off then let it charge for awhile then boot, or hold the power button for a good min
It won't turn on at all, so it can't get into the bootloader. Tried already.

I know you tried almost everything in the box, but when you plug it in the wall and press and hold the power button do you see the screen light up but still black?
If yes ( hopefully ) then continue holding power button then press VOL down til arrow pointing with START appears. Cycle through with VOL down til you see power off and select.
After it shuts down unplug from wall and replug and let it sit for a long awhile
If this didn't help at all sorry......good luck....warranty?

Nothing happens whatsoever mate, even while plugged into the charger. Tried the original charger, my s4 charger, my old HTC chargers, from the pc via USB, etc. None of them make any difference.
Got a feeling it might be the motherboard, as it has power. Can't be the display since I've tried getting a logcat from it after holding the power button for a while to make sure it would have turned on. ADB just kept saying "waiting for device" as if it wasn't plugged in, confirming it isn't even turning on.
Can anyone think of anything I've missed?

Can the pogo pins be used to charge? bit of a long shot and you`d need to buy/borrow a dock of some sort. Definitely sounds like a hardware failure issue.
