I replaced my broken screen recently, the battery had been lying dead for more than a month. Now after replacing the screen when i try to charge the phone, the RED LED blinks on a frequency of 7-10 seconds.
When I disconnect the battery flex and connect it to my PC it goes to fastboot mode, I was even able to flash a stock rom. When I connect it to main charger with the battery disconnected, display shows sony and turns off.
When reconnect the battery it won't display anything and the RED LED keeps blinking frequently. What might be the problem faulty battery ? or main board problem ?

The battery is completely discharged. Keep it on the wallcharger for 24 hours and then try to boot it.

But if it is discharged completely and when tried to recharge why would the red led keep blinking and not continuously glowing ?

It is not unusual. Just wait and you will see that it comes back on

Now the battery is charging I guess, RED LED is now glowing constantly which has been blinking earlier. Even though I was not able to Switch it ON.
The only way to recharge the phone is by using charging dock

Hi, I was using my XZ yesterday flawlessly and then out of no where it just turned off. I did everything I could find on the forums but it just sits there with the red Led permanently on. I left it charge overnight, when I woke up the led was green and the screen said it had a full charge. I turn it on, it gets to the lock screen and then shuts down again. It's sitting there again with the red led on as if the battery was drained completely in 1 min! What can I do about it? THANKS!

Hmm... Try doing this:
Get it charged till you get the led green, KEEP charging, and then turn it on. See if you can use it for 5 mins, 10 mins, even an hour. See if it turns off automatically. If it works fine while plugged, then that shouldn't be the problem of your ROM. Then, unplug the charger, and see if it shuts down soon. If it does, we can make sure it's the problem of your battery.

I'm gonna check that out thank you! .. and I'm pretty sure it's a ROM problem because it was fully charged and yet it shut down never to be woken up again til 5 min ago that I connected it to the PC and it briefly showed me the charging screen (battery completely drained) and then the Red Led came back on and the screen went away as soon as I disconnected it from the PC. I connected it to the wall charger but the screen didn't come on again. Thoughts about this? (also the computer briefly recognized the phone and then it didn't anymore) right now is plugged to the wall charger to see if the battery picks up, so I can proceed with all the flashing stuff.
What causes this type of problems? I really had high hopes with this phone, it's gorgeous to look at (the best design on a phone IMO) but it failed me
Hi, first of all sorry for my bad english.
I just bought Motorola Moto G 2 and i tried to start it - white LED lights and the device isn't starting, i thought that its normal that the battery isnt charged because its new phone. I plugged charger and it showed me that battery is about 50% charged, and when the charger is plugged phone starts and works normally, when i unplug the charger phone still works (havent checked for longer time but didnt immediatly turn off, just worked), but when i turn phone off and try to turn it on again LED lights like its discharged.
I tried charging to 100% and unplugging, doing reset but still the same. Only works when starting with charger plugged. What should I do? Is there any solution?

If the led is lighting up for just a moment, you didn't hold the power button long enough. If device is not starting up even after pressing power 5-10 sec.... customer service
Just happened after nowhere. I got my hands on a z1 from a friend with a fully charged battery. Since I didnt have a simcard on the phone I turned it off. Now it wont turn on and the the red light in blinking when charging. Looks like a discharged battery but i dont know what to do. It's plugged on a 2A charger for about half an hour now but there's no sign of life. is there anything I can do?
PS: the bootloader is locked and I didnt messed with the system in anyway, it's was just factory reset

Use the official charger (that is 1.5A) and report back..
Else try to send it to service
Left it charging the whole night but still just the blinking red led. Since it's not on warranty anymore I don't think it's worth sending it to service. I'll penalty try to reconnect the battery to see if it helps
@Castro27 Try flashing the stock firmware via flashtool its very easy and it will bring life to your phone...
I have a strange problem. My Z1 was in the original dock charger over the night. The alarm woke me up in the morning and the battery was 100% full. An hour later it did not switch on. I have tried to put it to a original USB charger and a red light is flashing fast and continuously. I have tried to press power+vol down key and nothing happens. Is my battery dead? I don't mean fully discharged, but dead.
Hi,
After many years of enjoying this magnificent phone the disaster came.
The phone discharged overnight and switched off. In the morning I had to send some texts, so plugged the wall charger into USB socked (a weak one ~500mA), after few moments a charging icon appeared and stated that battery has 1%. Ok, I really had to send those messages: I've pressed the power button and phone started to boot.
Sony logo: OK, purple wave, OK...
After 10-20 seconds it suddenly switched of, red LED started to blink.
I thought: OK, system startup needs a lot of power, maybe a charger is too week to keep up.
So I left phone for few more minutes to charge, but without success.
That was the last time I saw screen was on.
Phone is a C6903, running on a stock, rooted 14.6.A.1.236 with the recent XZRecovery.
Bootloader has been unlocked.
For the moment I've tried everything but opening back and doing the testport-trick.
When I connect the power only red led blinks (I left the phone charging overnight, no change).
When I try to enter flash mode: nothing happens but red blinking light.
When I try to start phone nothing happens at all.
But there is still hope:
I connected the phone to 2A charger using a magnetic cable.
Then I've connected normal USB cable to my PC, strange thing started to happen:
When I pressed volume Up (even after few minutes of connecting power+usb) the phone suddenly jumped to fastboot mode (blue led, it was discovered by PC, fastboot terminal was functional)
When I press power button, phone vibrates for a second, then the led pattern changes to: 1s red followed by 0.1s green, then long red, then it repeats...
I'm still unable to enter any recovery nor flashmode...
I'd really appreciate any help, have you got any ideas left how can I revive my phone?

Hi, this just happened to me, my phone has been dead for over 4 weeks with just the red led blinking. i tried the test point thing with no success at that point I gave up but last week i decided to get a new genuine battery and it worked it booted up. Your battery is just completely dead thats why it won't boot up!

Thanks for the info! I've ordered a replacement battery already.
I'll open my phone today and measure all voltages. I'll keep you updated.
Good luck

Yup! That was it (at least I think so, I don't have new battery yet)
The Al part of positive battery terminal was broken: I have no idea why, maybe because of age, oxidation and high currents that were drained from this LiPo cell...
Anyway I've managed to temporarily join two broken Al parts, kernel and recovery booted successfully.
Now I need to wait for a replacement battery.
Phone is alive again, thanks tilakpatel for help!
But the magnetic cable trick might be useful in other hardbrick cases: just connect magnetic charger, connect normal USB cable to PC and hold volUp. Phone should be able to enter fastboot even with completely drained battery...

no problem
So one morning I woke up and saw phone keeps rebooting(bootloop).I had breakfast then came back to pick it up,and i connected it to charger and phone was totaly dead.I tryed other cables but still same result.Only way to power it on is when I use original cable and connect it to charger/pc.Then red led turns on and display showing low battery,and led keeps blinking.Sometimes it can boot into system and works for few minutes and shuts off cuz 0%.I changed battery but everything is same,I also can go into TWRP.
**I TRIED EDL MODE/two pins or whatever and my PC is not showing Qualcom driver or anything else in relation with phone
i had same issue before, i simply just buy new cable and it working again!!
PS. Before i buy new cable i already had 3 type-c cable bot non of them working
I had the same issue an hour ago. My MI5 had ~25% charge left when I saw it shutting off, maybe I unknowingly did it. Then I decided to leave the phone in TWRP at night but in the morning it appeared to be dead. The red LED blinked only when I pressed the buttons, no turning on, fastboot or booting into TWRP was possible. When I plugged it into the charger an empty battery icon appeared with the red LED blinking continuously. After some time a new animated battery icon appeared, in the still turned off state, but this time showing the exact charge percentage (2%). It went to 3% and I turned it on with the power button.
Should be a faulty battery which needs to be replaced!
