X1 won't start, but shows red LED on USB.

Title says it.I've tried powering it on(the button is gone, so i had to push it with a knife), but no go.Whenever I connect the USB, a red LED is shown.Is it even working, or dead completely?I've recently got one, and it is untouched.Except for the fact it won't boot.USB connecting doesn't show anything, just the red LED, windows doesn't detect any USB drives or anything.

I have two batteries, first the old original one and second a "Tel1" china made, whatever. On the first battery this red LED never had apeared but on the second one, that red LED is present only when the battery voltage is very low (battery is drained). The difference is in the batteries, i think the original one has to have a shut down cicuit to prevent such low voltage drop. If charging for a long time did not help, there can be a hardware problem with the charge circuit inside the battery or worse as BrianXP7 said - on the motherboard.

[Q] what exactly is going on? phone not turning on

Hello everyone,
So I am new to XDA forums and I have a few questions about the HTC Vivid. I just recently purchased a phone for cheap just to practice doing how to root and do certain task on phones. When I purchased the phone I knew that the phone was not working properly. When I tried to turn on the phone nothing happen but I saw that the screen did light up in a black screen. I took the battery out and checked the battery and the connection to the battery on the phone everything seems fined. When I put the battery back in and tried to turn it on nothing happened. Think it might just be a dead battery I charged it all night. While changing I noticed the phone led light was not constant it kept blinking and a screen showed up real quick and it looked like it booted into recovery real quick and shut off. It kept doing this by itself for a while. (Cycling) Then it finally booted into the white boot screen with the HTC Logo. I thought the phone was finally going to work but nothing happened it continued the cycling process again for a while. Thinking there was a possibility of fixing the phone I connected it with my PC and using both Windows and Linux. When I connected it with Linux (Ubuntu) nothing seems to happen. When I connected it with Windows it does the same thing as if i charged it. The orange led light blinks a couple times and then becomes solid for a bit and blinks again life it was Morse code. This time I see a black screen lighting up more and boots fewer times booting into recovery. I think it booting into recovery because I remember the CWM. Through all this process while connected with my computer I see that it is attempting to connect with my computer but then shut off. After approximately 8-10 minutes of cycling i get the white screen with the HTC logo again and then the cycle happens again.
My question is what is the problem with the phone? A few things that pop into my mind is probably just the battery is fried, the microusb is bad, or something went wrong during the process of flashing something onto the phone. I was very detailed about the problem and what I noticed because like I said I purchased this phone only to learn how to root and do other various things on a phone. Is the phone salvageable? I will post a video later if my detailed description didn't make sense or you just have to see it happening.

OK, first thing to do is to charge the battery in an external charger. That is the *only* way to eliminate the battery as a problem. If the phone wont boot with a fully charged battery, see if it will boot into recovery mode. If you can't do that, it is quite possibly dead.

[HELP] Xperia Z brick?

hi,
sorry for my bad English,
I bought Xperia With a damaged touch. The phone is normally turn on. the touch did not work. I decided to take himself for the replacement of touch (glued to the LCD). I disassembly phone . before removing the motherboard still plugged in the battery to see if the battery will not hurt the dismantling of the display, the phone is turned saw the Sony logo and disconnected the battery (do not know if it was a good idea). After removing all nicely warmed the screen and slowly removing pieces touch. Unfortunately, at the end it turned out that a little too much it warmed, because the screen began to appear discolored, so were pissed, I ordered a new display and in the meantime, as I wait for the touch I wanted to see if it works. I have connected to the display board, tape, buttons and battery. Turned on, the phone vibrated and enough black screen. So I stitched it to "poop" and I wanted to run, but it was all the same. Computer can not detect, etc.. After some time, as it was plugged into usb turn on the red light. Ive loaded software program SUS, and after you press the power button flashing red LED 3 times. I left the phone on the charger overnight from nokia (1200mA), but it does not improve, after that, that when you try to turn the vibration and again, so much. The phone is detected in fastboot mode (blue LED) and flash (theoretically green), because as I press the phone turned off and hold down my Vol- is a second red LED will flash immediately changes to green and then turns off the computer recognizes the phone as SOMC Flash Device (SEMC not SOMC) and in this mode for the update service is normally upload the software to the end, in the Flashtool the same situation. I do not know if it's important, but after every uploading the software when you try to turn this unfortunate flashes red LED 3 times as if the battery is discharged. Could this be a defective battery? Phone before you got in my hands was lying unused for some time. How it got it it plugged into the car charger (840mA) for around 40min +/- and normally work. I do not remember whether if it was on some LED.

Why could you buy a Xperia Z with damaged touch? And why you try to repair it yourself?

If battery was working properly before the experiment that you did there must be something wrong that you must have did.
Try a different battery and see whether it solves issue or else you must have damage the mo-bo

My Xperia dead after remove battery.
Stuck in flash mode.
Fastboot and flash mode works. (Blue and green led)
unbrick from flashtool?

[Q] [Help Thread] Nook HD not booting at all

I recently went on a 3 month trip. Before I left, my nook was working perfectly fine, when i got back, it didn't work at all. It's not dead because i left it plugged in overnight but it still didn't turn on. when i plug it in the LED goes from orange to green and then off (or green to orange, i can't remember). The screen doesn't turn on at all. I can't get to recovery either.
This is a Nook HD, I believe it had CM11.
:crying:
Can this be fixed
or should i plan it's funeral

Same here
The same has happened to me. Screen doesn't turn on, but there is power, I can play it into my laptop and something is there, just not enough.
Good excuse for a new tablet!

It can be fixed. I've done it before. It has to do with the fstrim not being compatible with certain hardware versions of our device. If I can remember how I fixed it, I'll post it here. Trying to fix mine (again).

If would be fab if you could fix. Seems to be a common issue

I was able to fix it. YMMV.
1) Make sure the Nook is completely off and unplugged
2) Take out your sdcard
3) Hold down power button until the "battery depleted" icon shows, then promptly plug in the power before the icon disappears.
4) Let it set. The screen will go black, then it will attempt to boot and get stuck on the faint black screen, but this time, the charging light should stay amber.
If you want to be safe, wait until the device reboots itself. That could take hours though. If you're plugged into the wall wait at least 30 - 45 minutes before holding the power button down til it shuts down and then rebooting it (with the sdcard inserted).
Good luck, I hope it works for you.
EDIT: Also, I've read this may also have to do with wifi sending the device into some sort of strange bootloop when the screen is off. I personally believe it has more to do with the fstrim of JB but perhaps changing the wifi sleep policy may prevent this issue from happening again. I'm skeptical, but figured I'd pass that info along if anyone wants to try it as well.

Not sure we have the same problem. My screen doesn't come on at all, I don't get a battery depleted icon, no matter how long I hold in the power button. The only sign of life I get is when it's plugged in, when it goes from orange to green after about 10 seconds.
Thanks for the help, but I think it's a lost cause.

YMMV. But mine was the same issue. You should be able to get the icon by holding the power button down for 5 or 6 seconds. I'd say just eff with it until that icon appears. Try different button combinations. I used power and home trying to get the icon to show.

Anyway... since people are continually running into this kind of issue...
Give or take 21 seconds after turning orange it turns green during actual boot cycle into rom
Give or take 10 seconds after turning orange is cwm internal recovery.
After about 10 seconds the charging screen image disappears.
The charging screen image once finally no longer may not show up again until full power off/on (holding power button > 10 seconds or full battery discharge). Unplugging and plugging back in does nothing except making the device look bricked if there's too much light shining on it.
Device may not automatically leave the above state under a specific situation(s). May still need manual full power off/on.
Guessing 10 seconds could also be something else during the early/late boot process or other. The light changing color though should indicate that something is indeed happening.
Light should stay green during the boot process if its completely and fully no questions asked 100%. If you go based on that than yours doesn't appear to be completely fully charged which should either mean its turning on and using battery or not charging correctly.
The light turning off is curious. The device could be shutting off. If light comes back on a moment later then the device has rebooted. if the light stays off = n/a.
If its booting into recovery then the device would be available via adb. At that point it could be further evaluated.
On the off chance the screen was damaged it should boot and usb should be available via computer as well as adb.
If not then its probably toast unless its simply not getting a good enough current causing mislead battery stats and/or not enough energy to get to charging screen (bad wall power adapter in use, damaged power cable - though could be bad battery, defect, damage or whatever). OR there's some major error on behalf of the user happening (think should have tried that in the morning not while 1/2 asleep or came home from long trip and forget how that works).
Maybe the only other things are the emmc brick bug, was left sitting in the sun or heat or ocean air or other physical damage/defect even to the power port as well.
Or maybe it was mad that you left it. Shouldn't have hurt its feelings you know. At least its not crying battery acid on you.
That should just about cover everything except for the things not mentioned. Since its your device, you decide what happened.
Its complicated so anyone see any improvements, clarifications, or mistakes? Please put it in a post.

Bumping this thread to make it aware that there is a real answer. I have been able to duplicate this problem and rather easily too.
The problem is indeed from bad power. The device isn't receiving the correct amount of power needed to charge and start from a fully discharged battery.
To safely* duplicate this you can use a usb extension that isn't fully connected to the nook power cable. You may need to fully connect it first then slowly disconnect/connect till the light turns green when it should actually be charging. It won't actually charge in this state, or if it is, its very little and the battery percentage will continue to drop.
Leave the cable as is and unplugged. After the tablet is fully discharged, connect the usb cable. The light will change through the modes and turn off. The device will not turn on.
There are probably other ways to cause the problem like for instance a portable usb battery that doesn't put out enough juice (not the orange kind). Etc.
* It didn't hurt mine, but not my fault if it breaks your device.

I actually ended up fixing it yesterday!! I haven't touched it in about 3 months, and I was planning on just throwing it out getting rid of it some how. For the heck of it, I decided to plug it in, assuming that it was gonna go through the same process. But this time it went from green to amber, but it never went off. So I pressed the power button and the battery icon appeared. This was a really good sign. So I left plugged in for about 5 to 10 minutes then tried to power on.:fingers-crossed: As soon as I saw that '' Nook" boot up screen, my heart stopped. It booted up perfectly and I almost blew up from excitement :victory:. So I then flashed the stock firmware back onto it, so this would never happen again.
I guess the battery had to be completely depleted or just had to cool down. Idk but either way this was one heck of a miracle
So I recommend for anyone having this problem to just leave it off and don't mess with it. I wouldn't say for 3 months like I did but maybe test it each week or wait a month if you have good patience

Wow. Man, that's awesome! Glad you posted that update on it. Thought if you had posted an update it would be the opposite as in trashed it
Actually, I guess only you could answer if you had also moved/unplugged the power cable from the wall adapter or put it into a different wall adapter, etc. Thinking there could have been a difference there.
These modern day devices are so finicky, guess anything is possible. Like you say, maybe sitting without power is another answer.

From some experimentation I have etermined that your power adapter (that plugs into the outlet) is the issue. It does not like to be leaft plugged in indefinately. It will continually use power even when the nook is not plugged in.
Also, if you use a differnt adapter you will have the same problem unless it is also of the exact same voltage and amps.

Phone doesn't turn on

Hello everybody, i have a big problem with mi P9:
i was to replacing my cracked display and the battery, so i bought them. Took off the old display, replaced with the newer and the same process done with tha battery.
But, after that, i tried to turn on the phone....nothing. No vibration, to display, nothing. I plugged it to the power adapter, and a red led started to blink while charging, tried on more time to turn it on, and it get the bootup vibration, but still nothing on the display. After the short bootup vibration, the led blinked faster for 2 seconds, than nothing. After minutes, the phone show the charging screen with the 0% battery, not growing up. As last chance, i tried to unplug the battery, reconnect to the power adapter and...boom, it booted up with the animation. The phone show the unlock screen with the PIN screen, but only for 1 second: Battery low, the phone is about to turning off, and so it does.
Now, i tried with a different battery, but nothing. I don't know what is the problem. I was supposing about the motherboard flex, maybe i damaged it while removing the old battery, but i'm not sure. Can you help me?
Thank you!

No one can help me?
