[Q] Infinity won't start, just vibrating indefinitely

Hi gurus,
Updated the OTA patch today from ASUS. worked fine but got discharged while my son was playing with it. charged it and then tried to start it. It just won't boot. Starts vibrating which will not stop. Nothing on the screen. Pressing on Power button for about 10 seconds will stop it for a moment but will start again to vibrate after a short pause.
Tried the manual reset button, same result. Finally, pressed the power and Volume up button for 10 seconds which has atleast made it stop vibrating but is still dead. Tried to restart and same behaviour.
Has anyone seen this on infinity before? Have had it for 9 months and never been a problem.
Thanks in advance for your help.
Maybe a HDMI connection might let you see whats happening if its related to the display not working.
I am having the same problem. it vibrates..stop for 1 sec..then vibrates again and that's all..always black screen!! i think the problem (in my case) is my screen + digitizer coz my computer can recognize it as storage!
Yes my problem is the screen! i bought a micro HDMI to HDMI cable and everything works like a charm! The screen brightness works but no image at all!
Screenshots:http://db.tt/aBg7IXKd
Tried to charge it fully but to no avail.
still keeps just vibrating.
I work with leicesteruk (small world and why is he not using CROMi-X!?) and I think this is hard bricked! Device will not power on other than it vibrates once then on the second vibrate that normally signifies boot loader load it jus continuously vibrates and does nothing else. No screen, nothing.
We have tried various volume held down options and nothing works including reset hole and letting the battery drain. It still charges but just goes into continuously vibrating with no screen.
The only thing it will accept is power down plus volume down stops the vibrating after 20 secs if held down.
I have advised to RMA.
wow, that's extremely hard luck right after an update.
Was your tablet rooted, and were you using OTA root keeper?

No it was completely stock. Just a regular OTA. Note the device died whilst in use after the OTA had been applied the day before.

[Q] Restart Loop

Hi guys, I need some help with a restart issue. This is not a bootloop issue. When it's plugged into USB, it will go to the battery charge screen with the loading symbol, but then keep restarting itself from there. Holding the volume buttons does nothing, so I can't even get it into download mode. Any thoughts?

Try an usb jig which puts the device in download mode, you can find them cheap on ebay, I bought one because my buttons were damaged and it worked perfectly.

Hmmm...will this work for my situation, though? It seems like there's no charge on the battery either. I got this from someone else.

Check the power button it gets dirty from the inside and the button get stuck that happen to me when i was on stock froyo 2.2.1 without any modification no root no custom rom i tap the power button a couple of times and that fix the problem for some time but some time later the problem persist the solution was to take apart my infuse and clean the power button and the inside of the phone.
Sent from my SGH-I997 using XDA Premium 4 mobile app
Okay, cleaned inside with q-tip & alcohol, got the battery fully charged, got the jig & plugged it in. Still goes through the restart loop whether it's starting normally or going into download mode with the jig. What else could be causing this?

Z3 will not turn on no matter what

So this morning i unplugged my phone, fully charged, and used a flashlight app. Then all of the sudden my phone just went black and i have not been able to get it to do anything for over an hour and a half now. No matter what i do it will not turn on. Ive tried to power button/rockers combo to get it to turn on, nothing, Ive tried the little button in the sd card compartment, nothing.... Anyone else have this issue? I cannot find anything on the Z3 for this, only stuff for the older models... Thanks.
Hold volume up and power button until the phone vibrates. Then connect a USB cable to your computer while holding volume down on the phone. If the phone is recognised by the pc you should be able to flash your phone using flash tool and hopefully that will get you back up and running. That's the only solution I can think of. Maybe some other members might be able to help if this don't work.

Nothing... I cant get the phone to do anything at all. I really do not understand.
I can't help then mate other than suggesting taking it back to where you got it from or sending it to Sony. Hopefully somebody else can help you out to save you the hassle

Did you hold the buttons in for ages; literally 20 or 30 seconds?

Hello, my girlfriend have the same problem in his Xperia Z3. When she works his phone lying on the desk. She want call to me and the power/lock button don't work. She call to me from other mobile phone and she describe problem. After 10 seconds search in google I find a way to restart phone. She pressed little yellow switch under nano Sim/micro SD plug. Phone power down and never give up. Power button is dead, combinations : vol+ and power , vol- and power, vol+ and vol- and power also didn't work. When I plug the USB cable the charging will start normally. In screen I have a big battery icon with animation.
Maybe someone have similar problem with Z3 and know a solution??
Well if its the button, tap to wake could solve the problem till you decide to get it repaired.
It could also be a battery issue. Try charging for a few hours on a charger and then try turning on after connecting to a PC with phone drivers by holding the power button for like 10secs. That is the method used for HTC phones with similar issues.
The HTC One X had battery issues for some where it would not turn on until it was connected to thr charger for a few hours. I had, had the same issue you mentioned and tried the method mentioned above but never turned on. Repair shop tested the battery and eventually had to replace a bad mothetboard.
That is not normal and even if you could get it back from that sort of failure, you don't want this device unless it is fixed or replaced.

Still nothing. Power/unlock button is dead. Today I go to sell point (T-mobile Poland ) and leave for warranty repair. I used Xperia Z3 for 2 weeks
If you are within 14 days TMO should give you a brand new device.
I'm having the same problem too. I tried to use the flashlight app for the first time and it just completely bricked my Z3.

Just happened to me today- Xperia Z3 Compact
So last night, i left my phone to charge after reaching 5%. When I woke up, my phone won't start and it won't charge either. The LED indicator was not lighting when it is plugged.
I tried every trick:
1. Pressed down the power button in different lengths.
2. No. 1 but with the volume down key
3. Pressed down the yellow button on the sim card tray
4. Tested 5 different charger heads and different wires
5. Tried connecting to 2 different laptops to see if my phone will be recognized
I work close by a Sony Center so I was planning on passing by after work. I was already having a really bad day and my phone is not under warranty. Throughout the morning, I'd randomly check the power button if it will finally work. FORTUNATELY, during lunch, the LED indicator finally lit up! The batt was drained so I had to charge it and wait a few minutes before turning it on. Finally it's on. I don't know what the eff happened or if it is really resolved.
I'd still want to know what the hell is wrong with Xperia Z phones??
Mines 'died' twice, both times the only way I could get it to turn back on was to connect to magnetic charger dock/cable
this is really works on me.. !!! try this one.....

just do the no .3 ... and it works to me... thank u for posting this .. it helps me a lot.......
It's called the 'sudden death' bug and a small number of sony xperia phones die from it., including the Z3. It is more common in the Z3 Compact (I suffered from it and had to get it replaced). Just google sony Z3 sudden death.
Did the OP use a quick charger on his Z3? The reason I ask is that the repairer I sent my Z3C to originally said the motherboard was gone and needed to be replaced, possibly cased by current. I used to use a quick charger on my Z3C and wonder if it caused it as the phone worked perfectly for 6 weeks before dying.
There are several so called fixes and workarounds that work for some people, not all. Only a motherboard replacement fixes it properly.
Fix for Z3 not powering up / no charge LED
My Z3 would not power up and no charge LED when cable plugged in. Finally found this solution on Sonymobile support website which fixed my phone!
To force the device to restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") until the device has emitted three vibrations, and then release the OFF button. The device turns off automatically.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
If a forced restart procedure as described above doesn't succeed in turning on your device, you should try another kind of forced restart - the 2-minute restart procedure.
To force a 2-minute restart
Detach the SIM card slot cover.
Using the tip of a pen or similar object, press and hold down the small OFF button (generally indicated by the text "OFF") for 120 seconds (ignoring any vibrations), and then release the OFF button.
Charge the device until a charging icon appears on the screen.
Turn on your Xperia™ device.
I had to hold the 'off' button for about 60 seconds before the phone vibrated and sprung into life - phew!
I bought mine with the broken screen so I don't know for sure what happened. Bid won for $37
The led light came on when plugged in, but no vibrations. The computer recognized it and installed as the D6633. Properties show the battery had charged to 29%, 60%, 99%.
But clicking into it just shows a blank page. No folders, drive volumes, or anything.
However if it is not hooked up to a charger or computer then as well as no vibration there is no lights either. Does get a little warm though.
Bought the new display and powerflex. Still wont turn on, no vibrations, and only shows led when plugged in.
Tried the volume up, down, power, all three, reset button in sim tray.
PC Companion can't work with it. It almost worked once but said if there was a google account and I did not have the info I would be facing the whole account lock fiasco....No thank you. Can't even get it to recognize it for that option properly anymore anyway.
Could easily connect it into fastboot mode, but getting it into flash mode took much much much more effort. But eventually I did and flashed an image with flash tool. Went fine. Flashed everything......NO CHANGE......
I'm guessing at this point maybe the board was more damaged than seems....Though it's weird how the computer recognizes it and can flash everything.
Or there is a damaged power IC, transistor, capacitor, or something.
I really hope Sony took care of this in the Z5 and it is no longer an issue in future devices. It was said in a few comments above that only a few people are affected....Yet there are endless searches and pages with a dramatic number of users facing it.

Is my Moto G dead

Hey guys,
My Moto G LTE will not turn on. When I plug it in, the LED turns on and stays on, and I've been charging for a few hours. It still won't turn on no matter what I've tried, I've tried all common troubleshooting methods out there. It just shut off on me randomly and will not work anymore. I've searched a ton and can't seem to find anything.
Thanks for any help!
Connect it to your computer to see if anything appears in your device manager.

I was hoping that it would appear as a new device in the device manager so you could try this: http://forum.xda-developers.com/moto-g/help/how-to-revive-hard-bricked-moto-g-t2833798

Phone not booting at all

Hi,
I updated my phone, rebooted, it was all started up, it was installing some play store app updates, then my phone powered off and I'm not able to power it on anymore... Not at all! Tried every combination of buttons to press for a long time. Really nothing helped. Phone is not charging... I'm having a bummer here... Somebody faced this? I can bring it to the shop and get a new one but... Yeah... I'd rather not...
Ow pls help me Xda!
Try vol down + power for more than 7 seconds
I tried everything... What solved it was my wireless charger. It had to charge a couple of hours to have only 12%. But I tried powering the phone back on and there he was!! Woop woop
