Won't power on - T-Mobile myTouch 4G Slide

My myTouch worked for a really long time, even while overclocked. Today, when I was playing a game (Minecraft) it gets much hotter than normal. So I place it on my fan, just a floor fan, to let it cool down. Once it's cooled down, I resume my game. Out of nowhere, it just freezes and shuts off, then restarts, then turns off again once the BIOS splash goes away. It doesn't power on until I press the power button, then it only runs the BIOS splash and shuts off again. I try again, and it powers on to the boot screen, and then it shuts off again shortly after. I try it again, then just BIOS. And yet again, then a successful boot after letting it charge for about 10 minutes. I take a shower and when I come out it works fine, but 10 seconds into use, while I pressed the Bluetooth notification drawer widget button, it freezes and shuts off. From here on, it won't power on at all. I plug it into computer, nothing. All that works is the dim red LED on the trackpad. I press the power button, trackpad light turns on for a few seconds, then off. I press again, turns on for a second then off. When I hold the power button, the light is on and blinks every 10 seconds. No key combos work. Charge light does not come on when plugged in to either computer or wall charger. Any fix for this?

Not a fun situation, very possible your emmc is fried but there is a chance its just the battery. Let it charge overnight and if possible test a new battery
But there is a high likelihood you're going to need a new logicboard
If you're after a new device I do have a few oneplus one invites left...
Best of luck!

I have a very similar problem, i recently came across the mytouch 4g slide in the closet and remembered that it died due to charging overnight, 2-3 years ago lol, well the phone still does what it did after it died, no vibrations screen etc, the only sign of life is the two red lights one at the top left of the screen and the trackpad, could this be just the battery that got fried that night? Should of gotten this fixed those years ago but just got a new phone instead.

Possible but could also be a sign of a bad logic board

I have an extra one if any of you want it, not selling it, I can just mail it to ya, PM me about it, whatever. It's got moderate chips and dents, but works fine except sometimes the soft keys don't always work and you have to restart the phone. It has the latest CWM recovery and the latest 4.4.4 ION ROM. No SD card ships, but baseband and all wireless works, but uh, it's SIM locked and S is still ON. Bootloader is unlocked. I'll give you an extra screen and an extra battery, too.
I fixed the one I posted this thread about after I realized I could buy a new motherboard directly from HTC with a few hidden strings pulled (I'm just that special) and before that I ordered the one I'm talking about now that I'm trying to get rid of on Amazon.
So, yeah. best way to fix one is to get a new motherboard, the one from HTC's old stock warehouse that I got took a week or so to ship, and I cracked the casing opening it and almost ripped a connector ribbon, and I also think that this phone surpasses the G1 as the most mechanically intricate device I've disassembled. I've done a few, but man, this blew the top.

[Q] Completely unresponsive Xoom

I've got a 4G Xoom, that I bought new about 13 months ago. It's been great to me so far. I had it rooted and was running CM 9 on it and had been doing so for about a month without any issues.
Yesterday, it was plugged into the charger and I happen to glance at it and it was doing some strange things with the screen, flashing on/off, black lines on part of the screen. I powered it off and left it alone for an hour or so.
Since then, it's been completely unresponsive. I've tried Vol Up+Power button countless times without it working. The charge light (white) came on briefly while plugged in, but then went off, never to return. The only reaction I can get is that after holding Vol up+Power causes an orange light next to the front camera to blink twice. That's it.
Any suggestions? Is it completly dead?

Given that it's sealed, how is this done? I hadn't even considered cracking the case.

You may not need to remove the battery as several people have reported success with just slipping some paper between the contacts for 30+ seconds. You will need to open it up though and here's a post with info and pictures to guide you through that: http://forum.xda-developers.com/showthread.php?t=1578365
On edit: here's another thread with good info for you http://forum.xda-developers.com/showthread.php?t=1528706&page=3
Good luck.
Well, I did the paper under the battery terminals for 15 minutes and still no joy.
One item of note is that when I plug the charger in, I'm not getting a white (or green) light. At least not much of the time. Occasionally, I can wiggle the plug a bit and it will light up, but I'm not getting to green at all.
I can put a multimeter on the battery leads, does anyone know how many volts/amps I should be reading?
Are we sure that its not just a crap connection with the charging plug. It is a wimpy little pin and my Xoom needs me to do a rain dance to get it to charge. I have to plug it in, wait a few seconds and then the white light comes on , but only if the wire is flipped back over the top of the screen. Another thought is I use Tiamat ics and there is an option to have the light on or off during charge and I think it is set to off as default, maybe you didn't set that up. I would bet its something stupid and you just need to keep playing with the wire and see if you can get it on. Good luck.

[Q] RIP to my Sidekick

So today, as i was on my way to work I accidentally held down the lockscreen button and the power menu popped up (I was on Glorious Overdoes V2) in the middle of a text and i pressed reboot accidentally... My phone never rebooted... It was stuck on the black Sidekick 4G/T-Mobile screen and then it would go black, then once again that screen would pop up... I removed the battery and put it back in, and without me pressing any buttons the same screen came back up... I let it sit for a while and after 20minutes nothing changed except the phone got really hot. Luckily I had my OLD Nokia in my car and popped my SIM card in it so that i could continue having a phone. I let The Sidekick sit for 4hours and it was extremely hot and then eventually it just turned off completely (Im assuming the battery drained, it was at 90% 4 hours before.) I got home, plugged it in and it wouldn't even turn on the charging screen. Somebody told me that my Motherboard is fried but I don't know. I called T-mobile and they're going to send me a new phone since it's still in the 1-year warranty period.
Anyone know if they're going to be able to inspect my old device and find out if i rooted/flashed it? because i can't get into it or anything to ODIN
I feel like they will try putting a new battery in it, and if it still wont turn on you should be fine.
It got hot because the CPU was churning over something and couldn't enter a low power state. I bet you could coax the phone into download mode and reflash it.
what do you mean coax the phone into download mode? by using the button combo to get it into download mode when turning on? I've tried that and it doesn't work. I tried rebooting into recovery and that wont work either. Also, it wont charge the battery anymore...
I've always had a hard time getting into download mode, and my phone works fine. I just spent 5 minutes trying different combinations until I got it.
I've heard people say trackpad-power button, volume down-home-power button, volume up/down-put battery in-plug in USB, etc etc etc. But the only method that works for me is to put in the battery, plug in the USB, wait for the charging screen, then hold volume down-trackpad-power, releasing power as soon as the screen goes black
You say your phone is turning on as soon as the battery is inserted? What if you have it plugged into USB first?
I had the exact same problem, I sent it into samsung and they just replaced a part(never told me which one) and it was fixed. I did noticed that when the sccreen was poped open to show the keyboard, it would stop. But it's probably a loose cable like I've read before.

Worst case scenario if you can't figure it out here on XDA, you could always sell it on eBay for parts as defective.

[Q] HELP!!! my phone seems to have died

T-Mobile Sensation 4G. rooted, ICS (not exactly sure which version, likely custom)
I had a cracked screen, replaced it, ran into laggy screen problem but seemed to manage it for past few weeks.
Last night, battery ran out of juice. When I realized that, the screen is black but the bottom buttons r all lighted up in white. couldn't turn it off with the power button so I took the battery out. since then, pressing the power button will give me a phone that vibrates ONCE every 5-6 seconds. Nothing can change that state except taking out the battery.
I got home. plugging the phone into a desk charger (anker dock) and it starts giving me red light for a couple of seconds then darkness for 20sec then red light for 2s then darkness. plugging to the PC does the same thing.
I happen to have an extra battery (this seems to be the original one from HTC but kinda old). With this battery in, phone will only give me the black screen and vibrates and it will heats up a little bit when cable is plugged in.
I also check the voltage of both battery. original one (old from htc) gives 4.4v and aftermarket one (bought on ebay) gives 3.9v.
Vol.down + power button doesn't do anything. Computer won't recognize phone
Can any one please give me a hint of what's going on?
I also have this issue. Running CM9 Nightly 8-16. My battery was charging slowly, then the next day it was dead even though it was on charge overnight. I swapped batteries with another sensation ( I have 3 on my account ) and all I get is what the OP said. HELP PLEASE
Lol been way too long that I posted this. I ended up contacting HTC and they verified that I was still under warranty and fixed it for me. They even switch out the replacement screen and put in the original from htc-tmobile.

Moto G totally dead

Well, title says it all. My girlfriend's Moto G just went totally dead one day. I took it apart and measured that the battery voltage was very low. I also tried to charge the phone but all that it did is blinking white LED if Power button is pressed.
So, i went to eBay and purchased a new battery which arrived today. Popped it into Moto G aaand.. still no life. Even the white LED did flash no more Tried almost every single trick that I have found, still no luck, however few hours of charging with my G3 charger bring the white LED back to life. Now if I press Power button for a few seconds, white LED flashes quickly 2 times and then it goes away and nothing on screen. If I just let it charge without touching anything, I can see white LED flashing sometimes. Gonna leave it charging overnight and see if that brings it back to life. Any tricks what else I can do with this phone or should I just toss it away?

Can you enter fastboot mode, if you can that might indicate a sign of life.
Can't enter fastboot either Tried to press Vol - and Power, white LED flashed only one time but still no luck :/ Maybe the mobo is bad?
What you have done to it
Just standard use, but one night it just died. It did not wake with overnight charging. It is now sitting on my desk without charger, gonna try it in the evening when i go home. If it does not wake, i think it really is dead
Try looking up the led codes from Motorola's site or something. That might help if there are any. Seems to me that you have some hardware damage. But I might be wrong.
Try keeping it on charger for a few hours, then with charger connected, press power and keep it pressed for like 2 straight minutes. That should at least wake the device. If it doesn't work, I'm afraid it is busted :/

Tried that too, even pressed Power button over 2 minutes but all it does is white LED flashing randomly. Without charger it does absolutely nothing. I think the motherboard is busted
Seems like hardware damage to me too, use it for parts or sell it I guess.
why don't you take it to service center
it will be your best bet if engineer have a look whats the issue. just a get a approx cost. they will let you know. :good:

Phone shut itself off....

I took a nap today, and my phone had 60 percent. No background processes going or anything but the phone shut itself off anyways. Refused to turn back on or register that it was being charged when I plugged it in. I had to hold both volumes and the power button to hard reset it in to recovery (which is stock) to get it to power back on. Is there a fix for this or should I take the phone back and try something else? I haven't even had it a full 24 hours yet.
Something almost exactly like this happened with my HTC One X, after restarting it got stuck on boot... Eventually it would just show a charging light sometimes. Had to get the motherboard replaced.
On the other hand I have heard a bad battery can cause similar problems.
Just get it replaced, better safe than sorry.
Yea I just left the verizon. They pronounced my phone DOA. So they're giving me a brand new in box replacement but I have to drive to the only location in Colorado that has any white ones in Stock lol.
