Is my 4 days HTC Sensation bricked ?

Today i flashed my phone with the latest leaked rom from htc (insertcoin), battery was charged 100%, and when the battery died i took my battery out from it then back again and let it to charge.Now, after 6 hours i went to the phone to turn it on with no luck. I took the battery out and i tried again to power on, but the led is blinking. I tried to enter bootloader( vol down+ power button) but nothing happed. When i connect it to pc the computer recognize something. I don`t know linux, so i don`t know any commands. When i connect it to charge led stays on for a few seconds then stars blinking.
What can i do in this situation? Throw a brand new phone from the window?

did you drained your battery till its fully dead ?
now you need to charge it (boost) at a certain point for it to turn on
you need minimal of 3.6v on your battery to power on the phone.
you can see the voltage in your battery with a multimeter
i had this problem, I drained my battery completely, when I plug it in, the led flashing 11 times last 3 flashes are slow then goes dark.
(my battery had only 2,80v, and i had to boosted to 3.6v)
the original charger has an output 0f 3.6v, i was lucky to have a external batery charger, and it has 4,9v output, so was a little faster to boost my battery,
but this process can take hours.
-methed one by lalitsehgal21
1. Take a spare usb cable.
2. cut it from between.
3. Peel two wires black and red from tip.
4. connect black to (-) point and red to (+) point on batt and secure it via tape.
5. plug it in any power source usb or charger.
6. lve for 20 mins have coffee.
7. remove it and put in fone.
8. Last shot as its almost discharged keep charger plugged in till it rches 50 then flash new recovery.
9. Buy me coke.....coz i dt like beer

Please HELP ME :( "S3 will not power on due to no battery life"

Hello,
Two days ago, i was on a plane and my htc ons s S3 turn off due to battery go to less than 5% and loses all power, when i came to home i try to charge it but the LED still off and when i pressing the Power key does not turn on the device, i have left more than 5h and the issue still here.
if i remove the battery and than try to charge it with an externel adaptater sector, it will be charged or not ?
Please any idea ?

You might have to leave it alone on charge for at least 15-30 minutes until the LED shows up. Then you should be able to power it on.

I have already leave at all the night, the LED is up but i think the phone is not charging, when i try to power on it, nothing happened.

When a put the sector to the phone, the LED flash about 10s with orange color, and than it's still off for some time and it's turn on (orange color) but no charge on the battery.

Have you tried to boot to hboot while charging(hold vol down and hold power same time).
If you plug into pc does it show up or do anything in pc.

Not working

Have you tried holding the power button down for 10+ seconds?
The only other thing I can think of is something has frozen, maybe you can leave it off charge for a day or two until the battery is really completely flat, then charge it for a few hours without turning it on, then see what happens?

Thanks for all,
It's work now
but believe me I heated my phone around 7min because I'm in a very cold city now and when i touch the phone i find it very cold so i decided to put it near from a fireplace and it's work juste after.
ooooofffffff

[Q] Black screen but charging led lights up

Hi There,
Yesterday morning I went to work with a completely charged Moto G. When I arrived at work my screen was black and had become unresponsive.
The powerbutton doesn't wake up the phone, tried several times, holding it for more than 150sec. When connected to a charger (tried multipe) the charging led lights up, not blinking.
I have read on a motorola forum that this could indicate that there's insufficient power in the battery to activate the display.
However it was completely charged.
My Moto G has an unlocked bootloader, is rooted and has a custom rom (C-Rom, [ROM][AOSP][KK][12/05] **C-RoM** -4.4.2- -v6.5)
Is there anything I can try or is my phone a brick now?
Thanx in advance

The same problem
I am having the same problem too.
My moto G drained its battery until it shut down. Then i promptly went to charge it. The screen is blank and and notification light is on.
snooze1973 did u find a solution or is it now working?
PS My Moto g bootloader unlocked, stock rom,rooted and it is on the Faux123kernel
Thanks in advance

No luck Yet
No luck yet, left it on the charger for a whole night, still just the white charging led. No response to the power button.
But I refuse to believe it is completely dead. Before I had a HTC Desire S, tried many custom roms, never bricked it.
I just can't imagine what happend the day before yesterday.
Perhaps I'll try and find a more powerfull charger.

I think I found a solution. I followed these steps
1. Charge your phone via USB cable on your computer.
2. The white notification light should come on.
3. Then, do not touch any buttons on your phone.
4 The iconic Battery Logo(white background) should appear after several minutes.
Followed these steps and my phone eventually turned on
Good luck!!

Still no luck, trying a different cable (blackberry) now.

Not working for me, still just a beautiful white led indicator.
Start to think it's probably dead. Or battery thinks it's drained somehow.
Maybe anyone else has an idea?

Ok, I opened the Moto G and disconnected the battery, reconnected it after 10 sec. still no luck
Odd thing though and not very promising is that when the battery is disconnected the charging led still lights up when charger is connected.
Could this just mean that only the battery is fully drained or that the device is messed up?
Guess I going for a new one.

See if a new battery helps

Bought a new one today, so I can try and fix the other. First I will leave it for at least 24 hours.
Perhaps I will exchange the batteries at one time to see if that helps.

i had the same problem, i had no idea how to turn on my moto g.
anyone could help please

Black screen but charging led lights up
I am experiencing the same issue.
I bought a dead moto g for part replacement with my current moto g. Just out of curiosity, I plugged in the charger to the newly arrived moto g and observed the similar behavior.
To go further, I swapped the battery and tried to turn it on, and voila, it boots!! It has C-ROM. But it won't charge the battery any how. Its again back to
original behavior : No Screen, No Battery Charging, Only notification LED glows. I kept it on charger for whole night, but no luck.
The notification LED turns on even if I the battery is removed and charger is plugged in. What does that really mean?
Is there a probability that the charging circuit is broken? or it has something to do with bootloader, C-ROM and custom kernel? Does any one thinks reverting back to Stock ROM will help out in any way?

Same here...
Exactly the same with my little brother his Moto G 4G (1st gen) (stock rom, BL unlocked & rooted).
Solid white LED when plugged in, no other response.
The most advertised trick does not work (step 6: flashboot screen doesn't show up)
[SIZE=+1]Q28: Moto G will not power up (addition to Q16 and Q25)[/SIZE]
Plug it into the charger
Hold the VOL DOWN key
While still holding the VOL DOWN key, press and hold the POWER key
Hold both keys down for over 120 seconds. This is more than two minutes and will seem like a long time. You might want to time yourself to make sure you hold it longer than two minutes.
After holding the keys down for more than two minutes, release them.
The Flash Boot screen will display, and the Normal Reboot option will be highlighted
Press the VOL UP key and the device will start a normal reboot.
If you have tried the above and it didn't work, try this:
Plug in the phone for 15 minutes.
Proceed to Step 2 above.

It has been an hour on the charger of my Asus T100 Tablet (5V, 2A). Still no luck...
Due to the lack of other solutions, I guess all our phones are ready for RMA...
Update: an overnight charge on a 5V 1A charger did the trick. White led was gone this morning, booted normally.

I don't know why a USB charger and a PC connection should make any difference when the phone is not booted up.

I had the same problem. I solved it by removing the battery by opening the phone (mine was out of warranty) and taking it to repair shop where they charged the battery for an hour. Then when I put it back in, the phone rebooted normally with 10% charge.
But ever since, my battery life has deteriorated. Doesn't even last one full day. And I have had the same issue twice. I think I need a new battery.

I have a simple solution for that I have faced this issue long time ago and now I know a permanent solution. You all have usb cables in your house...just took a old one and cut it from the mini usb side..there are 4 wires...you have to care about red and black..open your moto g battery and took it off from the phone now connect the usb cable to your pc and touch the red wire to the positive and black to the negative ...just do this for 45 seconds and immediately connect the battery to the phone and connect the charger...phone will starts charging from 0 % pls do not wait to connect the switch and back cover just charge it upto 20 % the cover it up.....DO NOT LET YOUR BATTERY DRAIN MORE THAN 30% AS THIS IS COMMON PROBLEM IN LI ION BATTERIES...

Interesting, but how did you determine the negative and positive terminals on the battery flex? Can you, please, mark the attached photo of the battery of moto g to help the community?
Also, as a side note I think I discovered a solution - I connected the phone to my PC's usb 2.0 port and held the power button for 2 minutes - at which the LED blinked momentarily and then continues to shine. I left the phone connected and continued to browse for solutions to this battery charging dilemma - then about 5 minutes the LED stopped shining (and I breathed a sigh :silly: !!! becaue this is the sign of battery being charged!) and after about 30 minutes of charging I turned the phone on and it was 16% charged. Well I haven't been able to reproduce this solution (since, I have been extra cautious with the battery now!) but I would surely like to know if anyone can reproduce this solution:
1. Plug in your phone to USB 2.0 or 3.0 port with original moto g cable and confirm that the LED shines continuously.
2. Hold the power button for 2 minutes (which I discovered to be a long time if you just continuously stare at the phone!) after which you will notice that the led with blink momentarily before continuing to shine continuously. (I suggest you continue holding it for another 2 minutes after which the led will blink again momentarily)
3. Leave the power button and leave the phone attached to the port for at least 30 mins before attempting to power on.

Phone crashed and won't turn back on

I have a stock phone HTC One (M8) that has never been rooted. Today I pulled my phone out of my pocket and it wouldn't turn on. I've tried:
pressing the power button along with the volume up
Pressing power and volume down
Pressing power and volume up and down
I took it to the Verizon store and they said they would have to ship a refurb out to me. I wanted to check this forum to see if anyone has ideas before I get a refurb.
Thanks in advance!

Simular situation - will not power up or hold charge
Im S-off and unlocked .... I downloaded the new RUU 4.4.4 and everything was fine. the next day the battery drained completely and I plugged the charging cord in. I got the battery icon in the center of the screen and 0% life. The orange light is blinking, but the battery level doesn't change. I cannot get it to power up or get into the bootloader. Once I unplug the power cable the unit doesn't power on. if the keep the unit plugged In for a power source I'm still unable to boot. I'm totally out off ideas ... can I get someone to respond to help me out in this desperate time.

Can you try a different charger and cable? The blinking orange light is what they do when they are completely dead. Starts out blinking and wont go solid until enough charge is present to actually boot the phone.

I just upgraded to 4.4.4 as well maybe 3-4 days ago. I had been able to charge the phone a couple of times without issue right up until it wouldn't turn on yesterday.
I left the phone off the charger overnight and tried rebooting again this morning, and nothing.

Try this:
Battery is fully charged, but the device does not turn on
Plug device into the provided HTC wall charger that came with the device.
Press and hold the Power, Volume up and Volume down keys for 1 - 2 full minutes. The battery should re-calibrate and the device will then turn on.
or
Battery shows less than 0% charge level
Plug device into the provided HTC wall charger that came with the device.
Charge the device until the LED indicator glows solid red.
Attempt to power the device on as usual. If it will not power on, press and hold the Power and Volume up keys for 10 seconds while still on the charger.

I tried this just now, nothing.
When I hook up the charger, I don't get any lights to indicate that the phone is charging.
It's like the phone is bricked, but I haven't messed with any ROMs at all. I'm completely stock and locked.

I am unlocked but am having the same problem. I've had the phone since almost launch day and it's been fine until now.....all of a sudden it won't charge. I've tried many different cables and chargers that I know work, but nothing gives.
Were you able to figure anything out? Really don't want to have to get a refurb as I don't think I'll be able to get it rooted/unlocked anymore.
edit: After letting it "charge" for about an hour I was able to turn the phone back on. It said the battery was at 30% but was draining like 2% every 15-20 seconds. Looking at the settings it said the battery state was unkown (where it usually says not charging or charging). Something is definitely doing on here, but I have no idea what. I tried rebooting to recovery from the ROM but it just shut off. Now it's doing the same thing again (0%, won't turn on). Ugh!

LED is blinkin red.. no charging, no hard reset..

Hey,
yesterday night i wanted to check some Whatsapp and grabed my Z3 from the desk.. it was off and didnt react to powerbutton and even not to vol up + power..
When i pluged usb on it, the led was just blinking red.

did you try charging it over night?

Yes.. Didn't change anything
Sent from my GT-I9305 using xda app-developers app

Did you charge using pc or wall charger? That can make a huge difference. Try charging overnight with wall charger. Mine usually comes back to life after a few minutes at wall charger. Pc just doesn't charge quick enough

2 things you can try.
- the reset button at the SD and sim slot. Its a white square far at the left (display facing upwards).
Press and hold it for 10 seconds or so. (Don't press too strong)
But that didn't ever do anything to me, as I once tried to reboot at recovery mode with it.
- wait, wait and wait until the battery is empty (as it's not easily to be taken out). Then connect the stock standard wall charger. Wait for 15min. You can check what happens, but don't touch the phone.
If the led remains red, you can try to power it on, but chances is that it still doesn't work.
If everything else happens, you might be lucky (the led might not be red again).
Good lluck
I'm always curious if a thing worked, leave a message if success or not.

Hey,
after days on the charger i get following:
Phone charges for about 10 seconds.. screen goes on and so and then it stopps, fashes the red led and starts again. i believe the screen takes to much energy at this stage of charging.
i also know what happened.. at this night my phone showed me a looooong time 50% battery.. and it went off.. so the battery drained to much and i dunno how to get it back to work right without giving it back
i can enter fastboot but adb cant conect.. so i dont know how to make a backup other than this..

Sounds like your charger or your cable are faulty (at least, hopefully it's that)
With the wallcharger it should charge quick enough to not go off again.
Definitely try a different charger and cable, if that fails i recommend you claim warranty because then it's probably a hardware failure.

Chargers were all okay, tested them with my i9305, but with my Z3 they didnt work.. just a loop (Charging Loop i will call it yaaay)
I went to o2 today, they took it without charger or else and will repair it.. they gave me a S3 mini for this time (my s3 lte doesnt take any sim cards anymore x.x)
so, hardware failure i believe.. but it was the new 5.02 lollipop.. so be careful if the battery stucks at certain point!
