Z5 Premium won't turn on - Xperia Z5 Premium Q&A, Help & Troubleshooting

Z5 Premium not turning on
hello everyone,
PLEASE HELP ME!
My z5 premium was working fine.. battery was charged too, and suddenly it turned off, and it didn't turn on back again. I've tried all the different ways and solutions that should turn it back on:
hard reset didn't work
2 minutes hard reset didn't work
hard reset button didn't work
plugged it in using it's OEM charger and usb cable didn't work either and LED didn't lit up
plugged it in to the computer nothing happened, wasn't detected with no sign of life
I had to take off it's battery cover (using professional tools) unplugged the battery, connected the phone to the charger while the battery is unplugged, and nothing happened reconnected the battery back, and plugged the phone again to it's wall charger, and no sign of life.
i left it there all night long since the afternoon. and when i came back in the next morning to check if the phone is charging and the LED is lit up, but again NO SIGN OF LIFE!
(BTW, the phone is in mint condition and it was never been disassembled or repaired)
Please if anyone have an idea what this could be?
if anyone has encountered the same problem and went through the same of what I've been, and was able to repair it or find a solution PLEASE LET ME KNOW!
Now, I'm thinking of 2 things: either the battery is completely dead(damaged) or it's the mainboard which I don't hope to be.
PLEASE LET ME KNOW YOUR THOUGHTS ABOUT THIS!
Now, forget about any sort of software repair, as I explained above, the phone didn't succeed in that.
So, any help or suggestion would be so much appreciated.
Thank you all for taking time in reading and participating in this topic.
Have a good day.

Not happy reading this thread. Why so many issues with Sony Android... Anyway;;
- I recently had the same issue - or an issue in the same ball park. Phone Just died and refused to charge, but would show a red LED and try to boot when plugged in.
- Sent it to Sony, Hoping it is only a dead battery
The OP sounds like a they have a USB port issue or a board issue, also OP phone will no longer waterproof after removal of cover.
Unclear as to whether you have tried the following;
- Turn on whist holding camera button instead of Volume up/down. it is worth a try
- Try to grab an official sony charging cable- basically impossible to buy nowadays, maybe a PS4 controller cable? try it

My stock unrooted Z5p died like this in April. Have the same issue as the OP and tried all the same solutions. My Z5p had only been used indoors for months with WiFi before sudden death. Replacing the charging port did nothing. Using the OEM cable and charger with a new battery gets a 2 sec red light when connected to power and starts booting up until the swirls (gets past Sony Xperia and powered by android screens). Then the screen goes dark and shows the big battery for a couple of seconds.
I didn't realize there was a sudden death problem with Sony phones until I started trying to fix this. What's even crazier is that I had (have) the Xperia Z, Z Ultra, and the Z2. The Z2 was used in the rain constantly and even survived an ejection from a handlebar mount at 15mph onto asphalt. (All these phones were rooted and using custom ROMs/kernels.) Seems like Sony has a serious QC issue they're not taking about.

[Q] Xperia Arc - Dead phone Flashing?

Hi, my 6 week old xperia arc suddenly went dead and does not switch on. None of the led lights are on, whether I charge it with its cable or other chargers. I removed the battery and put it back on; tried the software update yet the PC can't detect the phone.
I would like to try flashing it before I take it to the store and test a different battery. Flashing seemed to work for someone in this thread with the same "symptoms" : http://forum.xda-developers.com/showthread.php?t=829850
I would be surprised if it was the battery after 6 weeks and an excellent battery life of one day and half throughout...
Could someone tell me how to flash the phone? Cheers, Alex
P.S.: Carrier is T-mobile, phone is great, can't say I regret switching RIM for Sony but I was expecting the software to be a bit more glitchy...
If it's of any relevance: if I press the power on button it vibrates a bit when its not connected to the mains. if I continue pressing it it vibrates a bit every 6/7 seconds. The leds are never on.
Have you tried the flashtool?
Try this :

More likely the battery or charger / cable is gone. Because if there is no LED what so ever then there is no power.

My Samsung Galaxy Nexus won't turn on

First of all I read all the possible posts here in the XDA forum about this problem but no one was able to help me :s
I was listening music with my cellphone than it crashed and turned of from nohting. My first thought was "Damm, it crashed!" and I removed the battery and after a couple minutes I put it back and than the cellphone never turned on again. No battery status is showing up, no leds, odin and flash mode doens't work either. I don't no what to do :s
I tried this:
◘ Unplug from USB, remove battery 5 min, put it back
◘ Odin and Flash mode
◘ Turn it on without battery on pc
◘ Turn it on while recharging
My GNexus model is a I9250 GSM.
Could you add some more details? How long the phone's been in operation, refurbished?, rooted?, your current ROM, kernel, radios, advanced kernel settings such as voltage changes, any tweaks, battery type, temperature.
This exactly happened to me on my DroidX. I spent 2 weeks trying everything to revive it including taking the phone apart before adding it to the pile and getting my current GNexus Toro.. so I know how much this sucks. I'm not an expert on phones bricking but I know that connections can go bad or come loose, especially if the phone has been dropped or other impact, components start to lose their integrity over time and voltage shorts 'burn out' op-amps. You mentioned listening to music, so I'm wandering about the IVA components burning out, which usually has voltage too high especially on boot... Hope you can get it working.

Well first of all I thank you for your concern and my phone is on again, thanks to my uncle. The phone is '4 months old', I rooted last month, bootloader unlocked and I was using samsung stock rom (4.2.1 JB). Yeah, that really suck monkey b*lls. If you got the same problem as me (I really hope not) that's what you should do: First remove the battery, plug the charger and than put the battery back. In my case, It kind "shorted" the battery and my phone is back on. I was reading posts and posts and discovered that GNexus has this problem and a lot. Dunno when it can happen again but I really don't want a paperweight. Once again, thank you!
Glad you got your Nexus back up and runnning. Thanks for posting back with details after you figured out the problem and got your phone working, +1 right there. There's always a good chance this will help out someone later on. :good:
Confirmation: balums worked for me
balums uncle's solution worked for me: specifically, (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button.
Thanks balums!
Does anybody have technical (design/EE) insight into what would cause this?
This was starting from a device that appeared totally dead.
The battery was *fully charged* (and showed up that way immediately when the device finally booted).
I had done the obvious things of removing/inserting the battery, cleaning contacts, checking the USB power connection.
Was about to pull it apart when I saw balums post, saving me huge time.
Device is about 16 months old. Stock OS and settings. First time this has happened.
Search terms:
CDMA (Verizon) Samsung Galaxy Nexus -- SCH-i515.
Phone won't boot. Device won't turn on. Won't start. Dead. No worky.
Thanks,
Seth
Awesome! You trick worked, balums!
Interestingly I also have the standard stock version of OS and Hardware which I bought 14 Months ago (nearly to the day). I was surfing over WiFi yesterday evening and when I turned the phone off I noticed the screen getting grey for a moment, not black. And this morning the Nexus just didn't turn on.
Anyway, thanks for the solution, have a nice day!
That is very odd because my i515 also did the exact same thing and I have owned it for 15 months. I can't wait to get home and try this trick. More to come.
Drew
Thanks!

Hey Balums,
My GNex didn't turn on this morning and I was really confused as to why it would do such a thing, until I saw your post. Thanks a lot for posting your uncle's remedy!
It fixed mine!

bookmarked. thanks op.
Galaxy nexus wont turn on or charge.
I tried (1) removed USB power, (2) removed battery, (3) applied USB power, (4) inserted battery, (5) press power button but my galaxy nexus still dont turn on. i have 4.2.2 stock rooted. i was downloading something and my screen become weird in colors and i cent use the phone. i turn it of and now wont turn on again or charge.
after unlocking and rooting i installed this touch recovery from google play. [ROOT]Recovery Tools
Excellent! balums' suggestion helped me. I thought I had tried this before but apparently didn't quite get this in the right sequence.
The only remaining issue I have now is that when it does turn on, I've got the thunderbolt on the battery indicator, the phone says it's charging at the lock screen, but when I go to Battery under Settings it says that the battery is discharging. This effectively has my phone in a state where I can't unplug it (battery is too low but it also doesn't appear to actually "charge"). I tried replacing the Micro USB charge port PCB board and came up with the same results. To me, this seems like a problem and may indicate a motherboard or battery connection issue. I used the "Battery Monitor Widget" and it indicated that it was getting AC power. Any thoughts?
Thanks to XDA and Balum's suggestion! I thought my phone just died! It was on 70somethign % battery last I looked, connected by USB to the PC and I don't know if I turned it off and walked away for a while or if it turned off by itself, but it would not turn on no matter what I did after I got back to my desk. It is on Android 4.3 takju stock not rooted.
Thank you all again for the instructions on how to revive the GNex!
Samsung Galaxy Nexus won't power up
I got a Samsung Galaxy Nexus. I got it from my cousin and therefore don't have any information about the rooting status as well as the ROM but i guess it was running stock. The phone won't turn ON, it is not detected in the computer. No LED or any other indication. I tried the above method which worked for many people but it failed. What is special about the phone is that the upper part of the screen is heating up more as compared to the rest of the phone. Can somebody help me fix this? Is this a hardware issue?
I have the EXACT same problem as you do. I have no idea where to start to try to fix it. I took a picture, then lines went squiggly across the screen, then it flickered, and died. I cannot power it on at all. I tried Uncle's tricks. No luck.
Anyone have some ideas on what to try? Thanks.

Also having the same problem. My Nexus has been rebooting randomly for the past week or so, and finally, this morning, it refuses to turn on at all.
It's a Verizon Galaxy Nexus running stock, but it's been rooted. I'm using the extended battery. The trick that was posted earlier in this thread doesn't seem to work for me. I've tried multiple USB cables and power sources.
I'm going to try the standard battery when I get home, but I'm not expecting positive results.
Work-around
About two months ago whenever I turned my Gnex off, it became totally unresponsive to all attempts to start again. After a lot of trial and error, I discovered that if I pulled the battery for 30-60 minutes and reinstalled, it would power on normally. I have completely wiped and rooted the phone and the problem persisted.
Today I thought about it some and realized there may be some residual charge in the phone, and my waiting period is to allow the charge to drain. To test this theory, I powered the phone down and then tried to restart - nada. Pulled and reset the battery - nada. Pulled the battery, shorted out all four pins that would make contact with the battery, reinstalled battery, and it powered right up. I have not been able to successfully repeat a fast restart when shorting out all four pins. Pulling the battery and waiting 30-60 mins still works.
Incidently about the same time, my screen has stopped auto rotating (and yes it is set to do so).

What are you doing exactly to short out the battery?
galaxy nexus reboot
my galaxy nexus is about 1 year old now and this is the first time that i've encountered a problem with it. It suddenly restarted, and will take about 5-7minutes before it opens, it will be open up to the "X" logo and when it reaches the normal screen it will restart again. I don't know whats wrong with it. please help/

You saved my Galaxy Nexus
Similar problem + water
Ok, so I have a similar situation I believe. My phone took a swim. I left it off and riced it. Later on after I believed it to be dry enough, i turned it on. (wow it freaking worked) After a few seconds of using the device checking screen the phone snapped off and went into a reboot. I waited until it came back and i shut it down and thought I'd let it go over night. I plugged it in and let it charge (charge icon was displaying). Everything looked good.
Fast forward. Morning time. I go to turn the phone on. Nothing.
This time the phone won't boot. Instead all i see is the white battery icon show up indicating the battery is 100%. When i plug it in to the charger i get the battery with the charging bolt, then it shows the normal battery indicator light. After that, I get nothing.
I tried the method I saw above. remove power, remove battery, apply usb power, insert battery, press power. Sadly it didn't work.
Anyone have any other ideas as to what might be going on?

What could be the problem pls? Sudden red blinking light...

Hello guys,
Wondering if you know what this issue could be. Basically, I had not used my xperia play for a few years and I wanted to try a few emulators on it now, so I tried to start it up and it worked twice, I could see the Sony logo and then it went onto a white screen (this is why I changed it on the 1st place and I think it'll need a Flex cable).
The problem is that after those 2 times, the mobile was vibrating when I tried to turn it on but nothing on the screen at all (not even the previous Sony logo I saw). I managed to plug the charger, get a static red light, which then turned orange and after like 10h that I checked again it was green.
I trid to start it up again, but still nothing. What's happening now is that as soon as I disconnected the charger when it was with the green light, when I connect the charger again it has a blinking red light that doesn't disappear (I've left it charging for hours but same light still there).
I tried to connect it to the computer, but I get a message of USB device not recognized, tried to udpate drivers for Xperia Play or someone mentioned some Zeus drivers, but still the computer cannot see it.
I was wondering if it'd be worth buying a new battery as well to see if this fixes the problem? What do you think? As mentioned, before the problem, I just saw it booting up correctly a couple of times and I didn't do anything afterwards...
Cheers
I could be wrong, but if the phone wasn't used for a few years, I would suspect your battery is part of the problem. I remember that I had an orange light and the phone wouldn't boot for me either when my battery was bad. I bought Hyperion batteries and the phone has worked great since.
As far as the phone not being recognized... I'm not sure. I would probably try uninstalling all Sony related drivers, then reboot the computer and reinstall them. Maybe see if you can get Flashtool to recognize the phone in Flashmode or FastBoot as well.
Do you think the computer should recognized the phone (xperia play in this case) even with a battery problem? for example, if the phone is switched off and the battery removed? (or does it need to be turned on?)
The phone definitely needs to be turned on to be recognized... either booted up normally or on fastboot mode, Flashmode, etc.... I can't remember if it will work in Flashmode or fastboot without the battery inserted... but I'm thinking it won't. I'm at work, but if I get some time to try it out tonight, I will report back.
If you could have a quick look at some point (no rush), out of curiosity, to see what happens if you try to connect it to the PC without the battery? I was thinking that it might be recognizable (as there's power coming in from the USB cable), however in my case I keep on getting the red blinking light when I plug it to the PC without the battery as well and I get the message saying that the device has not been recognized.
I've ordered a new battery anyway to see how it goes. I will learn something from the experience whether it finally ends up working or not...
Cheers!

Ok. I did some testing and you definitely need to have the battery inserted for fastboot mode or Flashmode to work. There is no response from the phone or the computer when only plugged in with the usb cable (and no battery) while holding back button or search button.
If your battery is bad (like we suspect after not using the phone for a few years)....then hopefully you'll be able to get into Flashmode/FastBoot again once you get your new battery.
As far as the screen turning white... it sounds like you're probably correct with thinking something could be wrong with your slider /flex cable.... but that's hard to know for sure. When my friend's flex cable was bad, it started out with lines through the screen and eventually had a strange textured grey/white appearance when the cable finally went completely out.
Just quick update for future reference in case someone faces a similar problem.
The red blinking light when trying to charge the mobile with an old battery was caused by the battery being faulty after a long period without use. I ordered a new one and as soon as I plugged it in to the charger, the light became orange (rather than red) and a little while later green.
Even with the battery charged, I had the problem that I couldn't see anything at all on the screen. The mobile vibrated when being switched on but then just a black screen. It turned out to be the 'flex cable'. It was totally knackered. Replaced with a new one and all working as well now.
Cheers!!

Z5P problems.

So I recently purchased a Z5P unlocked, with a contract in vodafone, regardless of that ive been having many problems with the Z5P. I love the phone and all its features. On to my problems and if anyone has an idea how to fix it please tell me!
1: my first problem is the water thing, if i take it in water its all fine, until water touches the jack, say if im in the rain, listening to music(which i have done to experience this problem) it will keep going into headphone mode, this isnt a huge problem, but if theres some work around to this id greatly appreciate it.
2: This is my biggest problem, the charging port just doesnt work properly! i connect it, it charges just fine, 100% in an hour or so, then it drains throughout the day i get home from college, from about 8-5/6 its down to about 50/45% i plug it in and no charge, or even worse half way through the day it'll pop up saying charger not charging battery, with nothing connected into the charger! its just died on me and will not charge at all, until i plugged it into my computer via fastboot and the lil blue light pops up and is now charging. Slowly, but is charging. any ideas as to why it isnt charging through wall charger? all official cables, and around 3 it was charging, in college fine. i get home and it doesnt charge.
other lil problems include the brightness thing, which i guess will be fixed in marshmallow? it keeps going into adaptive brightness even though i turn it off?
another problem is when i turn it off (Press the power button>Power off) it doesnt turn off, it forever restarts, red light, sony screen, black screen-repeat.
also another problem is the lag?! not in general, its all smooth but in snapchat the device starts lagging and then heats up? might be snapchat, i dunno. but the charging ones the big one!:crying::crying:
EDIT: i have done a full reset of my phone before it fully died on me, and this is the first time its ever fully died.
I don't know what country you're in but I'd return it for a new one. To many problems you got there...
Sent from my SGP311 using XDA Free mobile app
Can any body please help me Nd let me know how i can search messages in massaging app? using search option it only searching inside message content but i want to search by contact
I have the same problem as you, when i plug in the phone to the charge, nothing happend but, when i connected to my PC the phone appears to work fine until i restart it, after that, my pc wont reconice the phone either and i cant charge it until the battery is completely dead and of course, when i turn it off, the phone do the same as yours, white scren whit the sony logo after the red light and do the same thing over and over again, i tried hard reset twice but wont work, dont know what to do either............. did you connect your phone on a PC with windows XP in college???, because my problem start when i connecte to an old PC with Windows XP...

cm11 Arc won't charge, and battery is 0% - so the phone is dead. is there a solution?

hi.
my xperia arc (lt15a) has all of a sudden stopped responding to the charger - it won't charge at all!
tried other cables, tried connecting the usb to a desktop pc - but no respond!
the battery was at ~40%, and during the night I connected my powerbank to the charger, and the Arc to the powerbank (so trying to charge both of them simultaneously - something I never did).
in the morning I discovered that the phone didn't get charged.
I didn't worry much - I thought it was a bad cable, so I let the battery drain completely to 0%. but later I have discovered that it wouldn't recharge at all, and won't respond to a charger or a pc.
I have tried several things - which probably got the battery to get very drained-out. So now, if I try to power-on the device, it wouldn't turn on at all (it could turn on before), and the led near the micro usb port blinks in red for 3 times.
there is a very very tiny chance that a micro drop of rain got into the micro usb port, before the problem had started. But now I can't see any corrosion - maybe I don't know how to recognize it well enough? Anyway, I have tried to clean the port with alcohol and with electronic cleaning solvent (tuner cleaner) - but the phone still doesn't charge. maybe I didn't clean well? I really tried my best!
this Arc has mikeioannina's CM11 from 17.4.2016 - I used it for several months until now.
http://forum.xda-developers.com/showthread.php?t=2545354
the last thing I could do before the battery totally drained out was to enter the recovery mode (by turning the device on while holding the volume-up button), and then performing a factory reset. but it didn't help.
and I also want to mention that initially when the problem had started, when I connected the charger, sometimes the legacy xperia logo had appeared - but without the battery indicator afterwards (the phone just went off afterwards). now even this don't happen, and the phone doesn't respond at all to the charger. that's why I think it's a software problem, concerning the 3rd party rom that I've installed.
the mistake I've made was that I didn't try to reinstall the rom while there was still enough energy in the battery.... but I was abroad, and busy, and without a PC - so I couldn't perform it even if I was aware of the problem and wanted to solve it.
I don't have another battery or an external (desktop) battery-charger. and I am not enthusiast at buying these for this old phone (unless people here would be certain that it would definitely solve the problem).
I really want to keep using this device for a few more months - until the galaxy s8 / lg g6 would be released. I don't want to buy the current devices.
So could anybody help me?
hey i can help

the mistake I've made was that I didn't try to reinstall the rom while there was still enough energy in the battery.... but I was abroad, and busy, and without a PC - so I couldn't perform it even if I was aware of the problem and wanted to solve it.
I don't have another battery or an external (desktop) battery-charger. and I am not enthusiast at buying these for this old phone (unless people here would be certain that it would definitely solve the problem).
I really want to keep using this device for a few more months - until the galaxy s8 / lg g6 would be released. I don't want to buy the current devices.
So could anybody help me?
