Bootloop every 7 seconds!!! NO fastboot poosibly!!

Hi guys,
my phone just restarts today without any special hint of why it happened. Now it is in a bootloop with a restart every 7 seconds. I also cant get into fasboot because the phone automatically reboots in a too short period I used the CM10.2 unofficial now for 3 days without any problems.
Is there any way to get out of the loop? My phone was fully charged an hour ago so should last for the next 12 hours sad that i cant pull out the battery to turn it off.

Well that makes no sense I think. There were no problems before with the battery. Im also unable to navigate through bootloader with the volume keys. It seems it automatically pushes the power button all the time.
No I charged it to 100% this morning. No problems at all with battery life.
Is there really no way to turn the phone off? Well, bad bad HTC

Is the power button physically damaged and being depressed constantly? You may have to open the phone to take a look, or try GENTLY tapping the top-right corner off a hard surface.
All else failing...if you cannot reach bootloader or do anything practical with the phone, you will have no choice but to seek repair.

The power button is ok. I open the hox and i see no damage.
When you diconnect charger the hox turn off and dont Boot again. Right?

Now the HOX is empty. When I plug back in the charger the phone automatically starts bootlooping again.
The HOX does bootlooping ALL the time no matters if there is sth. plugged in.
The power button is not damaged. I dont want to open the case cause its glued and there is a risk to brake the display.

Yep I think so, too. So wainting until monday and sending it in for repairs -.-

Have you tried getting into fastboot by
Adb reboot fastboot
While it was bootlooping? It may pick it up and actually boot into bootloader. I'm not sure if you need acces to fastboot for this its worth a try

It is the power button that is constantly pressed. The circuit is disorted by water or something. I had the same thing.
If you open your HOX, wait till the white boot screen shows up, and then disconnect the power button flex cable, it boots normally. You can buy a replacement part for only a few dollars on eBay.

GSM Galaxy Nexus no longer charges

My Gnex, which I've had since March 2012, stopped charging.
I got a new battery, it didn't help
I got and replaced the daughterboard responsible for USB connections, and it STILL won't charge
I flashed complete stock android + recovery, nothing
Anyone have any idea what the hell is going on? I just want to be able to use my phone for a few more months till the Nexus 5 comes out!!!

I had this issue and only replaced the USB port on the bottom, and now it works.

Unfortunately that didn't fix mine. Computer can still see it, but it will not charge using any battery/cable/port combination

I had to change my main board

Same problem, but I haven't reflashed or done any sort of recovery. Problem first occured a few months ago after latest 4.3.0 update. Phone would only charge when plugged to USB or phone off. After a few hours the problem fixed itself. The only thing I did was revert back to stock launcher since it seemed like my custom launcher was using way too much memory at boot. Rebooted and the phone was charging. But honestly I think it was just a coincidence. Luck.
Thought the problem was gone but it happened again two days ago. I let my phone run dry (didn't have anywhere to charge). Got home plugged it in and it charged when off but not when booted. I have concluded it's software related. Chargers and USB cables all work, my different batteries work and micro usb port is clean. Device will charge when connected to PC in most modes but PTP works best (don't know why). PC doesn't regognize device however so I can't access it.
What fixed my problem was installing Wugs Toolkit for Nexus. I don't know why but it seems like when it was installing all the different components to communicate with my device it got it to work again. My device was connected to the PC during the install and suddenly rebooted by itself. After that everything was working perfectly.
Sadly I forgot to charge my phone overnight and it ran dry again and today I'm having the same problem again. Looking for a definitive fix, any suggestions are welcome.

My computer detects it as "Unkown device", but most often it will charge in PTP mode. Also, leave it connected to the PC for about 5 minutes. That's how long it takes for mine to start charging sometimes. This is just a temporary solution to actually charge the battery, but I'm sure we'll find the problem

Nope, mine's not charging while off or in PTP mode...

That really sucks, I wish there was a way I could help.. For the time being you could buy an external battery charger (not expensive), but that means having to take out the battery every night Otherwise there is always the hardware options like changing the USB port or the main board. Have you tried pushing the tongue inside the micro usb port up towards the middle? This is a known issue on the GNex and causes connection problems (because the slot is badly engineered)
There's one more thing I'd like you to try. Plugg your phone in through usb to any computer. On your nexus go to the dialer and type *#*#4636#*#* this will take you to the testing menu. Select "Battery information" and tell me what the top 2 lines say. When I'm plugged in with the wall charger it just says "Not charging" and "Unplugged". However when I connect through usb I get "Not charging" and "AC" or if I'm lucky "Charging" and "AC" which shows that the phone detects some sort of input.

[Q] HTC ONE (M8) is not starting... :(

Hi,
My uncle gave htc one m8 as a gift to me. He had bought it from Dubai. I have Started the mobile and filled all the personnel information to set up software. After that software update had come and it is downloading the update it is downloading slowly so i went outside i came back to home and checked my phone it was off i thought the charging is over and kept the charging but red led notification is not blinking after that i switched on the phone but phone doesn't start. The next day i went to the HTC authorized service centre and we have expalined the problem to them they said its a major problem but they are not saying the exact problem to us. and also we cannot send to service because it is dubai's model pls help me what do now...... Please help.............

First step would be to try another charger and cable.
If it still won't charge, it's likely the mini USB port or some other hardware issue.

try hard restart by holding the volume up until it restarts (maybe it will work)
do you feel the heat from your device or be in totally dark place do you see your screen bright?

You need to hold vol up and power for this to work, not just vol up.

I would suggest keeping it on the wall charger (not connected to PC) for several hours. Then try to power on again, or the button combo I gave above, as well as power+vol down.

Dead SGH-I317 what to look at first?

A friend of mine gave me dead Note-2, does not respond to buttons, battery inside was completely discharged.
I tried to hook it up to the charger, no signs of life, put precharged battery in, still nothing (in another words it does not respond to any buttons pushes or plugging into the charger).
Phone is in perfect cosmetical (close to like-new condition), no signs of water damage, so what else to look at or try to bring it back to life? I put the battery into my alive Note-2 it charges fine.

Phone ever dropped? Possible loose connection?
If you are using a Windows computer, does anything appear in device manager when the phone is connected?

Not a single dent on the besel or screen dry inside (I already took the back cover off), no mechanical damage inside, sadly no signs of life when hooked up to computer....

You took off the battery cover or the frame surrounding the motherboard, battery compartment, etc?
Have you tried leaving it on a charger for a few hours?

Yes took it apart all the way to PCB, no fully charged the battery up in another phone.

You did everything I could think of other than swapping out parts, I at a time.
The phone may have to be examined by a repair shop or Samsung.

Ok when the phone is left with the charged battery inside, the whole screen surface and battery gets noticeably warm, not burning, but evenly warm.

Is it possible that the screen is dead? The only way to really tell would be to put the motherboard into another phone. Don't know of any other way to really diagnose the problem as there is nothing on the screen when connected to a charger.

Its hard bricked, probably due to one of a few reasons.
1) it had a locked bootloader and someone flashed TWRP in an attempt to root it, a common cause.
2) someone rooted it, flashed TWRP then somewhere along the line flashed a ROM for a different device, also a common cause.
3) someone tried to update it manually by flashing a stock update in Odin but flashed the wrong firmware, or part of a firmware, again a common cause.
4) it had a locked bootloader and someone improperly tried to unlock it.
There are some more but aren't very common.
Have you tried a USB jig to see if it boots to download mode? If so you can flash the stock firmware and maybe revive it.

Its a device that costs $3-4 USD on eBay, it forces the device into download mode even of it won't with the buttons.
You can also make one with an old USB cord and a 300k resistor or combo of resistors equalling nor more and no less than 300k.

Have you tried booting to recovery? Vol up + Home + Power
Or Vol up + Power if you don't have home hardkey.
Have you tried booting to download mode? Vol down + Home + Power
Or
Vol down + Power
Does the device even vibrate when you hold power? Does PC show anything when you connect the device to PC?

Thanks found it, will make one tomorrow. So it works on newer ones as well?

Or, if you have a sdcard to put in it you can convert the sdcard to a bootable drive by using a debrick.img for your device, if you can find one or get someone to pull a copy from their device.
That makes the phone boot from sdcard, then you can restore everything back to the device then return the sdcard to normal use.

USB jig works on all Samsung devices, they are made that way purposely. also, it isn't guaranteed to boot it to download depending how bricked it is, but if its all possible for the device to perform the function, it will do it.

Yes I have SD card and another Note-2, where are the instructions how to make that debrick.img?
No PC does not see it, does not vibrate and I tried every button combination with no luck.

It took a few minutes to make USB jig, tested on another phone, works sadly does not do anything to the patient

Here, this is the method, the thread says its for S3 but the method works on other Samsung devices also, the debrick.IMG has to be from the same exact model, can't use a debrick.IMG from a different model number. Use this method, just find your debrick.IMG and use it, also, make sure you understand the partition structure on your note 2 and you know which partition is which and which mmcblk0 each of your partitions are in, if you get the partitions wrong you will have wasted your time.

This method doesn't work if the device doesn't at least vibrate when holding power.

I weep for dead notes...

plug into pc see if its even recognized if not lg waranty or a new battery

Try these steps
Hold down power button for 30s at least and try power again
If that doesn't work
Pull battery
If that doesn't work
Pull Battery and clean prongs where battery connects and battery prongs
Try different charger
If that doesn't work
Clean charging port with toothpick GENTLY....again GENTLY and dont jam it inbetween the side it doesn't fit where connector is

I have the same problem since today.
Does not start, not even Download Mode is accessable.
Seems like I have to send it to repair, but then I'll lose my data right?
I have data that I don't want to lose on that :/

Did you try steps I posted

Except for the different charger I've tried the options.
I think a different charger would not help anyways :/

plug into pc and see how device manager reconizes the device

Consider another charging block
If not go to local repair shop have them test the charging port for voltage
---------- Post added at 02:59 AM ---------- Previous post was at 02:56 AM ----------
Also try this....hold down the power button 30s
Considering you can't turn it on
Charge it for an hour or so. Battery might be completely drained
If your charging block, battery doesn't need to be replaced, and charging port has voltage
You would need to send it in
---------- Post added at 03:01 AM ---------- Previous post was at 02:59 AM ----------
Easy way to check the charging port without going to shop is
Does the cable going into charging port wiggle around and is loose? Or is it firm

He took the battery out and connect the phone to the computer, it's recognized as Qualcomm 9008 (or something like that). Is it the famous bootloop or is there anything we can do?

If he was not doing anything. Like trying to root it or downgrade then yes. Basicly bootloop. Lg waranty. If he was rooting or dowgrading. There are a few guys that may hve fixxed it but its a long complicated prosscess.

You might be able to follow the lgg4 hardbricked threads. Theres a few diffrent ones goin on now. In the generalsection. I dont own a g4 anymore. So if its changed and is bootlooped u may be able to disable the big cores. To stop it from bootlooping. Dont get hopes up yet. But thats a start

We've checking a few, seems like root is needed. Do you know how to root it? it's H818P MM, can't find it so far.
And there's a bit update. The phone was a few months died, now after I charge the battery using external charger and trying to turn on the phone. There's nothing happened, probably because the juice is not strong enough, but now there's a battery animation with a question mark when I connect it to the computer without the battery (still recharging the battery again).

Mention this before

This is a common issue, it happened to m last month. You can try anything with you PC it wont work because the problem comes from the main board.
Just contact LG and get your phone repaired.
