You hardbricked your phone like many people... You should have downgrade it to 4.4.4... As of now, there no fix

Phone not turning on after installing OTA!

So I tried updating from 4.4.3 to 4.4.4 OTA and for some reason during/after the install the screen went blank and I am now unable to turn the phone on. I tried holding the volume down and power button for two minutes but the screen stays black and I don't get any vibrations. Next I tried disconnecting the battery too and even that didn't fix anything either. I now have no clue what to do!

Anyone?

i'ts happen to me too

[Q] Moto G won't turn on

Hey! I have a Moto G LTE and about six hours ago I returned to stock after trying out some CM ROMs, everything was fine, I was in 4.4.4 with no issues and after updating all the apps that required it I had an update to Lollipop. I clicked the download button and after it finished downloading the phone restarted and started to update the system. After it was done the screen turned black and the phone just turned off. And that was it.
I literally have tried everything I saw in the net, I left it charging for about two hours, but it didn't solve anything, I pressed the Power + Volume Down button for 30 seconds, the Power button itself from 30 seconds to 5 minutes, yet nothing happens.
When I connect it to a PC Windows plays the sound when a device is connected, but it does not show the phone and doesn't seem to turn it on or anything.
Is there any way of solving this? I don't know what else to try, if at least I could get into the fastboot menu I will install a ROM, but I cannot.
Thanks in advance.

@Zox09 - How did you return to Stock? Did you use a firmware image? If so, provide the exact title.

I used Android 4.4.4 (Retail Europe) KXB21.14-L1.56-1 CID7 taken from this thread:
http://forum.xda-developers.com/moto-g/4g-development/xt1039-moto-g-4g-stock-firmware-kxb21-t2805619
It's the one I've always used and gave me no problems.

Try the following again.
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.

Thanks, I've already tried both of them a couple of hours ago and still nothing.
Someone in the Motorola Forum has said that I probably have bricked the device because of downgroading to 4.4.4 and then updating again. I didn't know this was possible since I have made this a couple of times with ROMs.
Is there anything else I can try?

The reference to hard-bricking due to doing a downgrade does not apply in your case. It would only apply if you upgraded to Lollipop, and then flashed the KitKat firmware. Even then, the hard-brick is due to a specific order of events: downgrading from 5.0.2 to 4.4.2 and OTA Update to 4.4.4.
It can be tricky following those steps sometimes. Are you sure the power cable is working? plugged into a wall socket?
If that method still fails to work, you have a hard-brick and need to wait with others for a Lollipop solution in this thead: http://forum.xda-developers.com/moto-g/help/how-to-revive-hard-bricked-moto-g-t2833798

I have tried with two different cables and two wall sockets, the USBs are one the original of the Moto G and the other from a LG tablet I have, and the sockets one from a Samsung mobile and the other from the tablet (the Moto G came with no wall socket), and in neither of them are working.
I think I'll have to wait for a solution :crying:
Thanks for your help anyway!

@lost101, I don't know how, but the LED just started working and it was on for a couple of minutes. I tried to turn on the device but it didn't work and the LED turned off a few seconds later. Does this actually mean something?

I've had a few occasions when I thought my Moto G was dead. Keep trying to charge it and follow the steps for another 24 hrs. That being said, I believe hard-bricked devices sometimes also only show some LED activity. You are best asking in the thread I mentioned above.

Problems with my d6633 Z3 Dual

Hallo people,
I have a very big problem with my d6633. I installed tonight TWRP - so fas, so good. After installing TWRP asked me to root the device, I said YES. My bootloader was unlocked. Then I couldn't exit TWRP. After every reboot the device started into TWRP. Now I can not start the device. I tried with Power+ Volume+, reset button - nothing.
Any suggestions?
Thanks for your help.

How much % did it have before you started the procedure?
Did you try holding down vol+ and then plugging it into USB?

Hello Jkay7,
Thanks for your support. My solution was to leave the device switched off over the night. Connected via original cable. Today in the morning my dyouzhengwen evice was detected via flash tool and as youzhengwen suggested I could flash the original ftf file.

Any help would be appreciated
Sony Xperia Z3 Dual D6633
I have tried just about every method seen. My problem with the flashtool or PC companion is that the phone is recognized by the computer but I can only start to turn the device on which I don't believe it actually boots. Broken display and new display does not power on.
Or it connects in fastboot by holding volume up when connecting. This shows a blue led.
But trying to connect in flash mode by holding power down just makes the led flash red then green continuously.
And for the pc companion it always says the connection was unsuccessful once the led turns green on the device.
I got the phone for only $40 in this condition. So I cannot say what entirely was wrong or what it's last working state was.
I bought a new screen and power flex cable. As well as a back plate and tempered glass protectors. I was going to wait until everything works perfect speakers and all before I sealed it tight with water proof adhesive stickers.
Even before I bought the new power flex the computer recognized it and the battery health and charge %. The battery was able to charge. But I couldn't turn the device on.
The computer confirmed that it had been at 29% after some time charging and then 100% after leaving it on charge.
Now with the new screen and power cable the phone still does nothing if not plugged it. The light was red at first, but then yellow, then after some time green when the battery fully charged. This was again even before the new parts.
I have to plug it in to try anything.
It goes red then starts to turn on and turns green.
But I hear no sound, get no vibrations, the computer only sees it as the phone and shows absolutely nothing on the removable disk. Just blank when I click on the drive volume. But it is seen as an Xperia D6633 phone or fastboot Android device.
I've tried the reset button, holding power and volume up, volume down, all three. Tried my factory cable. Different cables, different ports, uninstalling it from service manager and letting the flash tool recognize and install it.
I also tried the new display on the old power flex and the old display on the new power flex.
Nothing changed, no vibrations, no sounds, system never actually fully starts as far as I can tell, and cannot connect in flash mode only fast boot. And the flashable file is only seen in flash mode. Fastboot can only see the folder but it is ready to flash files as far as I can tell.

@xdathekilljoy
That's a lot of money you're putting into an (apparently) broken phone Brave!
Okay so what happens if you hold Vol+ while it's shut down and then connect it to USB, the LED turns blue, right?
So why does flashing it from there on not work?

Well it didn't seem that broken at first and both it and the display were only about 37 piece. Power flex was almost 10. Seemed like a rightful price.
Yes the led turns blue and it is in fastboot mode. The flash file seems to only be readable for flashing in flash mode "volume down". I can see the folder of the flash file in fastboot mode " volume up ", but not in a flashable format.
And when connecting " volume down " it fails a connection while the led just flashes green to red to green to red continually

Two updates
1. I thought I should mention that when I do plug the phone in to a charger or computer the top does get a bit warm or hot as well as the led turns on. Different color depending.
2. With much fiddling and trying if holding the volume down button for different lengths of time while connecting up a computer I finally got it to connect in flash mode and flashed a file...... No change.
At this point maybe I should try a new battery for the hell of it even though this one seems to be working.
Or there is a minute hardware damage somewhere. Maybe the power ic? Or s capacitor?

Help - my honor 8 was block - No access Fastboot Mode or Debugging Mode

Hello,
I downgraded my Honor 8 via Rollback and installed the Rom FRD-L09C432B131.
But my phone is stuck on the blue Android startup screen.
I can not use the Volume +, Volume - or Power buttons.
All I can do is let it turn off by itself when the battery is at 0%.
When I put it on, it turns on by itself. Arrives on a blue screen. Reboot once and then stays eternally on the blue screen while heating up enormously.
I have no access to the Recovery, erecovery or via the computer (by plugging it into a USB port).
Thanks

Once your phone turns off, press power button amd volume up button together. This should take you to recovery. Or you can't access this at all?

I can not turn off my phone. It goes off when the battery is at 0%.
If I put on USB or mains, it recharges and restarts automatically. And I can not stop it ...
When I plug it into a USB port, the Power, Volume + or Volume buttons are ineffective.
And when it's plugged into the PC, it does not show up!
So I do not have access ... except perhaps by a software that would force the connection ... or a manipulation other than Power / Volume ..

When I say reboots, it is a program to display the Android blue screen and hangs on it!

does it say android or honor?
going to dload is kinda tricky sometimes and should be done when connected to wall adapter, not pc
can you keep vol- and power pressed while your phone is connected to pc. keep them pressed even after the phone restarts. dont let go. it might take some time. does it go to fastboot?

He can't even boot to recovery.
Sent from my Honor 8 using XDA Labs

Ohhh, sorry my bad

dats prolly because he has mismatched files for the os he's running. he should deffo check if he can go to fastboot. the fact that he cant go to dload doesnt really mean anything because i cant do it either 40% of the time. its a bit iffy. the fact remains, if it boots to honor logo, means some type of os is up there. if he can go to fastboot he can flash stock recovery/recovery2 and try dload again. without proper recovery combo he wont be able to flash anything anyways and warranty prolly wont cover it since its users fault, esp if he has unlocked warning.

Thank you :laugh:

Similar to me, only way is go into bootloader mode, then charge the phone for awhile, you cant do nothing cuz of 0% battery, flash stock recovery, update via dload or direct wifi recovery.

He can't go to fastboot

if he completely bricked it, he'd be stuck at black screen/android logo, not honor logo. either he's not telling us everything (ran out of juice while upgrading / error while flashing / flashing wrong rom), there is no chance all key partitions got wiped if the process finished successfully. meaning at least he should be able to fastboot cause thats the first thing flashing alongside bootloader. no way any type of system partition is up there, and bl/fb is not, even if they are from a different OS. h8 can be stubborn at times, but keeping the cable in pc and holding vol_down+power for good 20s deffo will force it to at least reboot. thats the only way. if this doesnt work, you should take it to a service center.

I guess it's better if he takes it to the service center

Nothing works. So I have to send it to the service center

Thank you all !
