[Q] Inspire 4G flashes full battery screen when plugged in, won't turn on.

I plugged my phone in last night and when I woke up today it was off. I pulled out the charging cord and held the power button with no effect. Thinking the cord may have slipped partly out and let the phone die, I plugged it back in and was greeted by the battery charging screen, showing full charge. I pressed the power button and the phone went black. On further investigation, it seems my press of the power button didn't have to do with it turning off, as whenever I plug it in it shows the full battery screen for a couple of seconds before turning off again. If I unplug it and plug it back in it just repeats this. I've reseated the battery, I've tried holding volume down and the power button, and nothing's changed the phone's behavior. The phone is completely stock, and never opened beyond the battery and card doors.
It's pretty old and I'm pretty sure I do have an upgrade available, so I'm not too upset if I have to buy a new phone, but I'd like to confirm that it is FUBAR before I go that far, and I'd like to be able to extract my data if possible. Any suggestions would be appreciated.

If you have access to another battery, you could try that, but since you're seeing the full battery symbol I'm guessing that that's not the issue. You can always recover your sdcard data by putting it in a card reader, but the phone's apps, app data, and settings may be more difficult.

Well, turns out the problem was much less serious than I thought: my charging cord has bitten the dust. I'm not sure why I've been seeing the full battery, but when I took it to the AT&T store, the person who helped me plugged it in and it started right up. I just need to get a cable that's not my years-old piece of crap that came with the phone.

[Q] HTC 8x stuck and rebooting after logo screen

Hello,
Had a perfectly fine HTC 8x till this morning. Then the pet at home chewed on the USB cable while the phone was charging .. I suspect the power cables may have shorted with the data cables. In any case, now the phone is totally dead when the charger is disconnected. If I reconnect the charger (new cable) then the phone vibrates, afer that the screen lights up for about 10 seconds with the HTC logo and then it switches off - it keeps doing this till the time I remove the charging cable. The Red charging LED does not come on at any time. I have tried the hard reset with Vol down and power key etc. and that did not work. Any help to revive the phone would be greatly appreciated.
Thanks & regards

I bought one listed for parts on ebay a while back that would do a constant boot loop. what i did was buy a cheap phone tool kit 2$ off ebay as well. removed the rear shell on the phone. dang phone is held with sticky adhesive. its take a minute to separate the housing and screen. if you have watched those videos on youtube where there using a blow drier to heat the plastic to take the phone apart is completely nuts. It only takes patients and dont force it . then disconnected the battery. 2 whole screws. woo hoo.. i couldn't do the hard reset either because the phone woudnt charge in off-mode. just constant boot loop. i had no choice to battery pull. strange thing was the charging light would always stay on even when it was unplugged. once the battery had been disconnected from the pcb it hasn't had any problems.
T-MOBUS HTC 8x Developer Unlocked, Sim Unlocked, and Running Windows 8.1

[SOLVED] Disconnect the battery from the phone for few seconds
Problems faced:
1. Boot Loop
2. Factory Reset using Phone buttons never worked, tried everything and never ever got the " ! " icon
3. Phone keeps restarting showing the HTC logo without "quietly brilliant" ( if you don't see that probably not going to boot the OS)
4. Phone does not work at all unless connected to phone charger
SOLUTION:
After trying almost every possible thing i got this to make it work.
1. Open the back cover ( you will need a hair dryer, check YouTube)
2. Unscrew just the two screws at the bottom of your phone and disconnect the clip-pin thingy (this connects the battery to the phone) for a few seconds. ( it has a metallic cover kinda thing)
Press the power button and your phone will go back to normal.
Make sure you connect anything that gets disconnected in the process... they are quite strong so dont worry, nothing will break or cut off, but do be careful.

hi there ok i found a solution you need to take the cover off and the plug in the charger because a button is stuck
there is only 2 screws you need to unscrew and boob it works

My Case

MY CASE... I've posted a thread explaining that...
This procedure works.. but in my case not at 100% fine... cause i can't insert back the sim card since the bootloops return if i do it...
That left us with a software issue i've not been able to solve yet...
Best regards...

Bootloop + Power Menu problem

So today i started having bootloops, it was showing the Powered by Android screen for 2 seconds then booting again over and over for few hours
Now after it somehow got fixed by itself, i managed to turn the phone ON and to clear Cache
So far there are not bootloops anymore
BUT
huge BUT
the phone is poping the Power Menu most of the time, and then every touch on the screen just "presses" on the Shut Down option
If i press on the Power button myself it shut him down automatically ...
EDIT:
Would like to add, that i never unlocked it, it's the regular OTA version.
I doubt a wipe wll help, but i really wont mind if thats the case
Its almost like something pressing the Power button sometimes, but even WITHOUT the back case it still pops that power menu. even if no one is touching it at all it still pops it once in a while, which cause shut downs once in a while ...

So i woke up
The phone is off, i cant turn it on
I charge it for few hours already and still nothing happens the power button doesnt do nothing, it doesnt vibrate
So i connect it to my PC, it shows it as a Marshal something in the device manager but it KEEPS disconnecting and reconnecting every 2 seconds
I have found a "fix ur bricked phone" threads but they all using a tool that needs the phone connected to the PC, well my phone cant stay connected more than 5 seconds for some reason [ different cables, different computers] it keeps on popping in and out

Did you drop your phone in the water or something? Wet or damp from the rain maybe?
And did you try connecting it while in fastboot or recovery mode?

Maybe wet from Humidity but thats all
i cant reach fastboot nor recovery
as now it all black, not turning on not even for a bootloop
This problem happen when the phone is getting wet ? its certainly didn't but maybe i should "fix" it as a wet phone should be fixed? should i open it and dry it out? maybe take the battery out? its not that easy to take it out tho

I had a phone which was wet from the rain, it made the power button faulty. It would randomly turn screen on off like in your case. I took it to the repair shop and they cleaned the insides and it was fine again. If you're sure it's not the rain or anything then maybe that's not the reason, just a guess.
How about plugging in the charger? Does it light up? If it lit up and you cant turn it on after maybe its the power button problem.

plugging the charger doesnt do nothing
Although i got a portable charger with a led , the led turns on when i plug the One, BUT, the led bar doesnt decrease even after few hours, so its like "trying" to charge but not charging anything

Try this from OnePlus Customer Support:
2. Power cycle the One by holding the Power button for 20 seconds 5 times.
3. Attempt to start the phone by holding down the Power button along with the Volume down button to start recovery mode and performing a factory reset.

or hold Power button with the Volumn up button to see if you can get into fastboot mode.

lol bro... seriously.. you really think i didnt try that stuff before opening a thread?
I already scanned the entire web and no one with the same issue have posted a fix thread
one plus doesnt even care about their customers

Is this the guide you said you saw? http://forum.xda-developers.com/oneplus-one/general/guide-unbrick-oneplus-one-t3013732
Why not give it a try? Follow the steps and see if you are able to unbrick your phone.

I mean there's not much you can do if you can't even turn on your device in the first place :/

Unresponsive / Dead Phone - Any ideas?

So i recently picked up an XT1254 for a great deal. The phone is pristine, not a scratch on it. It looks brand new. It is totally unresponsive. If I plug it in the light on my charger turns from blue to green, telling me it's fast charging. But nothing from the phones LED. Also if I place it on a charging pad, color changes as well. I tried both options over night and still nothing. The phone does get warm (usual amount), leading me to believe it is charging the battery.
Holding the power button - nothing (no vibration, no moto logo, no LED responce)
Holding power + vol down - nothing ( = )
USB to PC - phone is not detected at all (I have ADB and current moto drivers installed)
I opened it up, and everything seems to be in order. No loose connections, no water damage. I checked the battery, and it reads roughly 2.5 volts across each pair of pins. Should it be reading 3.7-4 volts across each pair?
I unfortunately don't have another phone to check the MB, battery and LCD against.
I don't have a SIM installed in it, but I doubt it makes a difference?
Any ideas or advice would be greatly appreciated! Thanks-

Quite low for li-ion/-poly, I don't think it ever sees 3v or under in normal circumstances. It might be well into "damaging the battery" territory at this point, and it should certainly be higher after charging it for a while...might be a goner.
Have you tried removing the battery completely and running it off the USB cord? I would expect it to, if nothing else, bring the screen up complaining of a bad/missing battery. That said, I've never tried unplugging mine to see what happens, so no real idea.
I would suggest trying to fabricate a factory cable (which would provide power directly, ignoring battery status), but I don't know if post-OMAP Motorolas are physically configured to use them. If they aren't, it'll do nothing at best and burn up traces at worst : \
Also, holding Vol - while plugging it in should bring the boot menu up, regardless of available battery charge (therefore serving as a quick test to see if the power button is the problem). But that might go out the window as well if the battery is deader than a doornail.

It doesn't. When I fresh-install a ROM, I remove my SIM card to make sure none of my data gets used before I can turn various unwanted syncs/auto-updates off. The phone doesn't care at all, and nowadays Google isn't too whiny about a missing SIM either.

Hello guys.
Sorry for reviving an old thread, but I have similar problem with my Droid Turbo. During the replacement of the battery and speaker, I noticed oxidized resistors near the proximity sensor (which wasn't working since the purchase of the phone second-hand). I have cleaned the oxidized residue with ethanol and assembled the phone. After pressing the power button, the touch buttons light up and phone was vibrating every 20s but the screen was blank. So I disassembled it again to check all the connections but everything was fine. Since then, the phone won't even vibrate, just heats up a lot after holding power button. I have tried both batteries, speakers and also powering the phone without battery (only power cord connected). Both batteries are shoving around 3.8V.
Do you please have any suggestions how to fix the phone? Or should I assume that the motherboard died?
Thanks

(Help)Hard bricked U11

Never thought I would run into this moment that I need to ask for help on the forum, but I guess this is my last hope.
Here's the story:
I was on Oreo firmware and thinking of going back to Nougat because there are some apps only work on Nougat at this moment and I overall prefer Nougat design.
My phone was on S-off so I thought it would be perfectly fine for me to just flash Nougat firmware then flash the Nougat rom I desired like the good old days.
So then I launched Sunshine app, passed the compatibility test and the phone rebooted to download mode with S-off shown, everything was working fine so far.
And here was the problem happened, I typed in the command"fastboot flash zip firmwareXXX.zip".
Terminal showed error needs to reboot and flash again immediately as normal, the phone rebooted but never come back to download mode.
Now it only stays on black screen, if I tilt the phone a bit I can see the backlight glowing.
I've tried hard reset by holding power and volume down, it will reboot but still stays on black screen, neither system nor bootloader is accessible.
Even plugging to the computer detects nothing, not even QHSUSB_BULK mode.
However, the phone is able to charge though, I hook up the usb cable with a digital meter and it shows 5 volts and 0.5 amp.
I'm running out of solutions, I've searched through the entire forum and see no one has the similar experience.
This is the first time I hard brick a phone, been a loyal HTC user since good old Desire HD days.
If anyone has experience or solution for this, a kindly help is appreciated, thanks!

Have you held the power and volume down button both together for exactly 1 minute,
I have a u11 that took for ever to reboot with corrupt os youll notice the capacative buttons start flash if its doing something or going to reset after about 30 seconds if not and nothin happens
Take the backing off and unplug the battery,
To do this heat the backing up with a hair dryer and get some really fine guitar picks, work your way arround slowly, in my case the U11 was not glass backed only plastic and was original backing ive heard they are glass now though so be careful,
Now with the backing off and exposed, take all of the 5 or 6 screws out from the plastic ariel cover with NFC chip attached (chip is gold bend it up off battery it is not glued down)
Then from the left of the device at the bottom of the plastic cover with ncf chip on it you should see a slight gap where the vibration motor is located and sits
Get a rounded pair of tweezer and insert just the tip into the opening and very carefully pry it up, it make take a while as some of the adhesive from the backing will be holding it down,
After that is off you have now exposed the devices PCB,
From the battery youll see the connector making its way to the PCB port disconnect it and reconnect it now try to boot directly to download mode with
Power
Volume down
Both at the same time, if this did not work the disconnect the battery again and wait 24hrs for the static electricity to disperse and try again, had this work on a completely frozen unresponisve evo 10 and u11 + and also my U11
Still no luck id say the emmc on the board has gone haywire either that or possibly one of the thermal transistors has blown in which youll see either black and burnt or white and powdery,
Im a phone tech you shouldnt have any problems doing all this just take your time,
Good luck mate

I've tried holding volume down and power buttons both for around 5 mins, no capacitive button blinking.
However I can tell the phone reboots several times during the procedure by seeing the backlight goes black and light up.
And about the reconnect battery route, I guess I'll just do it anyway, since the repairing price might be the same as buying a new one.
Thanks for the reply, mate!

Sounds like the logic board is trying to initialize but there isnt sufficient power to boot it,
its kinda like when you take the battery out of a phone then plug it on to charge without a battery and there is nothing but a lit up black screen and nothing else happens as theres not enough power to boot, this sounds the same to me as there are no red or green light after the orange when plugged in,
Get a hair dryer and heat the back of the phone up a few times and then plug it into charge to see if you cant boost the cells back to life, do this a few times,
If no change id most certainly suggest removing your back cover and unplugging and replugging the battery, once unplugged leave it for a few minutes, then plug back this will refresh the chips (especially emmc as this contains your entire system and bootloader, including download mode, RUU mode)
as soon as battery is reconnected plug it in on charge and try to boot it to download mode straight away also look for any change in the batteries light colour and any blinking,
the orange light when first plugged in is normal but should blink once or twice only then change to a solid red for discharged and charging or solid green green when near on 100% charged
If the above does not work disconnect the battery for 24 hours and try again, this will fully drain any static electricity in the device that may be lingering,
If still nothing after the 24 hours buy an OEM battery from ebay and install yourself, once you have the back cover off youll see the battery takes up 3/4 of the phones actual internal size,
Same as the back cover get your hair dryer place a shamwow or thick cloth over the PCB board then heat the battery up (NOT TO MUCH THOUGH only so its hot to the touch), then with the really thin guitar picks again (they should be bendable easily and flexible) work your way around the battery to cut through the adhesive securing it down,
CAUTION be very very careful the adhesive is strong keep the battery heated at all times to avoid pericing the battery and or damaaging the lcd as this is what its secured to, just take your time and work slowly do not force it out, once all the adhesive is cut it will remove easily by using the guitar pick insert between battery and housing and gently turn the pick from left to right and will pop out, (you will see the battery move when using pick from left to right if not you havent cut the adhesive properly work around the battery once again until you get movement from it)
Sorry for the long reply haha but dont send it to htc they are absolute rubbish hope this helps ive tried to be as detailed as i can its actually alot harder trying to explain it than it actually is to do it
