Help! Phone won't boot up at all

So, I woke up this morning and I went to go check some messages on my phone, but when I checked, the phone wouldn't turn on. I charged it like I usually did and when I got to it, the blue led light was flashing. Not brightly, but just like it would try to turn on, but it can't so the light slowly fades away. I tried to hold the power + volume buttons (both up and down) but it still wouldn't do anything. Any help before I take it into sprint?

can you charge the battery? is the battery loose? I would take it to sprint and let them check it out.

Yeah. I think I might just take it back to sprint. But it won't charge at all I think.

Pull the battery and leave it out for a few minutes then try again.

I've done that and I actually start seeing the empty battery logo. But It's only for a second. I think there's a problem with the battery or the charger thing

Okay, My phone actually started up now. The battery is not charging though

Just kidding. It's charging. Anyone know if I should be worried about anything?

Are you using an after market charger?

Get a brand new quality USB cable. A HUGE amount of issues can be resolved by just doint this, believe me.

I was using the charger cable it came with but connected to my computer

well your computer USB port can only push 500mA out max. sounds like its undercharging your phone. the stock charger pushes 1000mA or 1A.

Arc S Won't charge, replace usb port?

Hi! Last night i had like three percent battery when i left it for the day. Today, in the morning, the phone was dead. Now, i thought maybe there was a little bit of power left, so i turned it on. It worked for like 15 secs and then turned off again because of the battery running out. I went up and put it on charge and it didn't turn on ,the led just flashed red three times, repeatedly til' I released the power button. I have now tried with three different wall chargers, includin the original, and also two different usb-cables. Everytime, just the three red led flashes again. Is there anything i can do besides replacing the micro-usb charging port, and if that really is the only option, is it just soldering to replace it, is there any instructions. Btw i'm running CM10 (unlocked bootloader) if that helps. Thanks in advance! :fingers-crossed:
EDIT: Okay, it really seems like this port is indeed broken. Will try to replace it myself and see how it goes along.

[Q] HTC One X Discharged and Now Won't Charge At All

Hi, I have a One X which discharged to nothing on Saturday night/Sunday morning as I was in hospital and my wife was using it to call people.
I had a similar problem in June, once dead it won't take any charge, it won't power up normally and it won't boot up either with the volume down being pressed at the same time.
Nothing lights or flashes.
In June I sent it to O2 and it came back fixed, but I've had a conversation today to say the warranty is voided as I've rooted it.
They are saying that it needs a new main board as it is rooted. I kept explaining that I don't need a new board, just some charge to be put into the battery.
I do think that I've tried everything this time, and last, to get the phone started again without sending it away, but I'd appreciate advice on getting it up and running and how best to deal with O2, what arguments to use etc.
Many thanks

Try plugging it in to the charger and pressing the power button quickly 3 times. Keep trying that until it powers on and then charge as usual.

Just Plug it in With Official HTC Cable In A New PC which has USB 2 or greater port. Eventually after sometime you will c blinking red light. Once you get blinking red light pull out and plug it back in again after some time red led will become stable. at this point turn on the phone.
Once the OS loads again repeat Plug out Plug In USB Cable. It should now charge. If it stops charging repeat Plug out Plug again. Hope this helps.
I am doing this now and i have reached 12%. Hope this helps you

I left it charging all night but pressing the button quickly did not work.
I'm now trying leaving it plugged into my PC.
Any idea how long before this might show a red light?
Also, is this any different to leaving it plugged into a power lead?
Cheers

Actually it should show the blinking red light after 20 appx minutes after charging. Then after few minutes it should get stable, and then you can powerup the device.

Hmmmm, back from lunch, it's been plugged in since 9.00 this morning, 4 hours, and nothing.
Repair needed?

Ok, having taken it to a repairer I was told there was nothing wrong with the battery, charging unit etc, it was a complicated matter that they couldn't sort out.
Does anybody know of a reputable repairer who may be able to take a look please?
Many thanks.

Flashing Red Light, Now Phone Unresponsive

So I woke up this morning and my phone was A-OK. Charged to 100% overnight, and I left it plugged in while getting ready for work. I came back to it 20 minutes later and it was really warm/borderline hot to the touch (through a case). The battery was down to 85% yet still plugged in. I then drove to the train station 5 minutes away and it went down to near 50%, still really warm/hot.
Streamed some music and watched some Netflix on the 90 minute ride, and the battery was down to 35%. At this point I turned the phone off because it was still hot.
Plugged it in to charge at the office, and got a blinking red light for about 10 seconds. It then went solid red and stayed that way until I unplugged it 4 hours later. The phone was still quite warm, but no longer hot. Hold down the power button... nothing. Plug it back in, same red light pattern. I got nervous at this point and hit up good old El Goog to see what could be wrong.
Found a lot of threads pointing to the One X suffering this fate, along with a few One's. Followed the advise of holding VolUp + VolDown + Power for 2 minutes. The phone got hot again. Unplugged the phone, removed the SIM, and held the buttons again. The phone had cooled off dramatically while doing this, to the point that it is now cold to the touch. Reinserted the SIM, and plugged it in again... no light at all this time.
From this point on, the various threads disagree on the next steps. Plugging it in to the computer yields no light, just like an wall charger. I don't have the HTC cord with me at work. I've tried a Nokia micro USB cable and a Sony wall charger. Other suggestions call for leaving the phone off (like I have a choice on that part) and unplugged for several hours. Others say to mash the Power button for 10-20 times and that may cause it to power on.
Any suggestions on how I should proceed with this? My phone is unlocked, so I'd love to avoid replacing it.

Have you tried the bright light trick? Hold the phone under a bright light (really bright light, the brighter the better) and hold down the volume button + power for 15-20 seconds. That should get you into your bootloader. This will tell you whether or not its rom based, or phone based.
If you cant even get into your bootloader, it sounds like a hardware problem. If you can get into your bootloader but it will not boot to your rom, then its software.
Thats all I got for now. Sorry.

Seriously sounds like a battery/charging issue, gives all signs of a discharging battery. That would explain the heat build-up.

Was you using the charger that came with it? Or are you using a different charger? I once used my motorola cord to charge my phone and it felt like it was going to burst in to flames. I then got the HTC cord that came with the phone and it cooled down.

No luck on the bright light trick. I tried holding just power, power + down, power + up, and power + both underneath a fairly bright fluorescent light.

I don't have the OEM charger here, but I was using it at home to charge it. I'm hoping leaving it alone for another 4 hours will bring it back to life on the HTC cable.

Lets hope that it didnt turn on because the battery died. Hopefully the OEM HTC cable/charger will fix your issue.
If your battery is truly completely drained, it may take a few seconds for the light to finally come on... so dont freak out in the first 10 seconds.

Your battery could of went bad. Does your phone look like it has swelled anywhere from the battery expanding ?

I'm trying to remain calm until I get home. I haven't gotten a light in 30+ minutes of being connected to the Sony charger, but I'm chocking that up to it not being the HTC original.

It's tough to properly gauge it with my eyes, but nothing looks off. If I press down on the center of the phone at the top, the it does not lift off the table. If that push from the center at the bottom, it does lift off ever so slightly. But I don't know if this is because of the camera location or what.

Called up Verizon just to make sure there's no other method that I didn't try, and they advised me to get a replacement. I've got a few days to try and get this thing working before I'll have to send it back and say goodbye to root.
Interestingly enough, they were sure to warn me about physical damage and being subject to a $299 charge if there is any damage. But they didn't make any mention about if the device is found to be unlocked.

Well the cooling down certainly could have been the battery finally being completely dead. Maybe stop in a Verizon store to try another battery? No chance a bad SIM card could cause this right?

Try another battery? You mean just pop off the back cover, take out the old battery and try a new one? You're one sick troll.

I did remove the SIM before doing some of the steps as there were reports that a missing one will cause the phone to pop into recovery. I really hope I can get this one back to life so I don't have to wait for an S-Off exploit to root again.

Got home, plugged it in for several hours, no light. Looks to be quite dead.

Really sorry to hear this man.
I would keep it off 12-24 hours.
try it out.
also I have sent back MANY HTC Dev unlocked phones, they just flash the new software re-setting it back to S-ON, and stock. I don't think they really give a ****, esp if it's not an issue from say, S-OFF.

That's a pisser. My One has been rock solid. Sounds like a really weird issue. I doubt it's recoverable. I'd just go for the replacement. Generally even if it's unlocked they won't have any issue replacing it. In fact, here is Australia, retailers aren't allowed tor efuse warranty claims even if the device has been unlocked, rooted etc...
Perhaps put it into a bag and into the freezer for a few hours. That can sometimes resolve battery issues.

Did I read it correct that you were not able to go into the bootloader? (full Power off > vol down + power)?
If that's the case then you should head for a replacement.. if it is dead they probably wont be able to fire it up to check if its locked or not anyway

Very good point, and by the time they do, the guys at the repair center can't physically go and find every rooted phone, then bring it to corporates attention, they get the phones, reflash the software fix the problems listed and out goes another returd. I mean refub, sorry.

Tab S 8.4 died suddenly..HELP!!!

Hi guys.
I think my problem has been covered before but I can't seem to get the tablet to turn back on.
It was working fine. It was on about 20% battery so I put it on charge overnight like I often do. I went to use it the next day and it was switched off. I tried to turn it back on but nothing. No light indicating it was charging either. I have tried holding power and volume up and down and home keys (All combinations) and nothing has worked. Done this whilst plugged in to the mains and laptop and unplugged as well. Nothing. I've even tried taking the back cover off and unplugging the battery cable and plugging it back in but still nothing. I haven't been able to find anything else that might help.
I've ordered a new battery, hoping it's just the battery that has died.
Anyone else have any ideas or experiences with a similar problem?
Thanks in advance
Simon

Try holding POWER + VOL DOWN for about 20 secs.

Thanks for the reply.
I have tried this numerous times. Nothing.
I ordered a new battery and fitted it but there is still no sign of life. I'm thinking its maybe a motherboard issue. Anybody else have any thoughts??

MATE if u still have warranty return it, but if not get it replaced, u can do ur own diagnostic and use a multimeter to check if power from battery to motherboard has voltage, if thats to hard for u to do, get it repaired at ur local authorized Samsung dealer.

anybody near you got ipad? use their charger and see if it can power up or not.
