[Q] Sleep of Death

Well got the sleep of death last night.
Set the Alarm, woke up this morning after the alarm time to find the Z with the notification light blinking but otherwise completely unresponsive.
Had to do a power plus vol + reset.
Anything I can do to track down the cause?
Phone is rooted but bootloader is still locked.

Could be an application.

check carefully applications that u install after root
the apps that need su grant.

Well the only permanent SU grant I've given is to better battery stats.
If it happens again I may try revoking the grant and see if it makes a difference.

I have to add here, I'm regularly getting the Sleep of Death on mine, and it's not rooted, still completely stock... so I'm thinking it's not related to rooting or any kind of root-level process.
Initially I thought it might be to do with the new-fangled 'Stamina' mode - so that's turned off too now, but I'm STILL getting it - however, some days I don't - and there's absolutely no pattern to it at all.
My next step, though I don't want to do it, will be to take it back to factory settings (no installed apps, no accounts, no syncing etc) and see if I still get it then - if I do, then it'll be jolly well back into its little Sony box and back from whence it came toute-suite... (or quickly, if that doesn't mean quickly). LOL.
As an aside, on older Xperia models (was just reading) the Sleep of Death was a 'feature' but when connecting to USB, it was recognised as the QUALCOMM device - I've just plugged my death-sleeping Xperia Z into usb, and I get NOTHING.
Question: Does everyone get a green flashing LED when in Sleep-of-Death? Mine's always green, and flashing around 1Hz (once a second) for around 300ms (I would imagine, haven't timed it!)
Perhaps an Android Update will resolve it....!

Not sure if it will help, but on my old V the sleep of death disappeared when I switched off wifi

It's interesting you say that; as I was away a few days ago, and forgot my charger, so put the phone into Airplane Mode overnight, and for 2 nights, didn't have the Sleep of Death.
Tonight, I will try with no wifi, and see what happens.
Thanks!

Can I ask where did you buy your XZ? like all the people, who have this SOD problem, could you all write, where did you bought your XZs? may be it could clarify thing...
I bought mine in HK about a week now, and nothing like SOD or anything faulty, yet (touch wood, thank god). So I was thinking may be it was one of the earlier batches from manufacturer, that were defected.

Well, mine is UK based, and supplied by CPW (Carphone Warehouse) - fully unbranded, network independent device.
To add to the SoD issue, it happened earlier on without being on charge - and NO notification light flashing - it was, in effect behaving like it was turned off - no LEDs, no screen, no response to buttons. Hard reset (Vol Up+Pwr) fixed it again - 90% battery remaining when it happened.
It's gotta be down to some software related thing... surely...? Just - what?! Roll on 4.2.2

It does seem to be completely random some days I would get 2 SODs other times nothing for 2-3 days. It happened in the first 24hours I bought the phone. Mine was bought in Taiwan CC602, it's completely sold out so no replacement until the next batch arrives. However, the softkey reboot isn't such a big problem for me.
Stamina mode does seem to make it happen more often as well as task killers like ESTask Manager. Mine happened before root and after root. It has only happened when it hasn't been charging.

Mine was from Clove.co.uk, it's a sim free model.
I haven't had the problem since so hopefully it was a once off or at least is pretty rare.
I don't use stamina mode and I usually leave the wifi on.

Got SOD yesterday. At one moment i took the phone and tried to wake it up, but there`s no response from the phone. Set it in charging dock and wait for 15 minutes, still nothing, LED notification was totally off. After hard reset (3 times vibro) phone started fine. Stamina mode is always off, phone is rooted but the BL is factory locked. Bought it officially in Russia, color is black, 13W06.

After Xperia T and Xperia V, “Sleep Of Death” issue, has also appeared on the new Sony Xperia Z. There is nothing official right now, only some testimonials, from people who own the device, in forums and blogs.They experienced this issue with the Android 4.1.2 – Build 10.1.A.1.350 installed.
I have ordered Xperia Z and waiting eagerly for it.. but after knowing all these things.. I am very much worried.. I sold my beautiful Arc to buy this grand cell.. :crying:

This has happened to me too, the first time was within 24 hours after taking it out of the box. So far it has happened like 3 times in a week. 2 times it was overnight and the other time it was within 30 mins of the last use. I'm currently testing if turning wifi off before I go to sleep would make the problem go away but I'm not sure on that yet.

C6603 /Unlock Bootloader
I have the Xperia Z with unlocked bootloader. I don't know what I did. I think I flashed the wrong file using the Flashtool on the mac. I have been having trouble with my Xperia Z on the .253 firmware. It still thinks its on the old firmware and tries to update and then it fails.
I couldn't get rid of the message, so I used Root Delete (or something like that) to just *hide* the app, but then I decided to try a default .253 ROM and it didn't have the 4G/LTS like mine did, so I tried to replace the ROM using the DE Generic one, and that was fine, but it was missing some apps. So I thought I'd use my CWM backup on my SD card. For some reason CWM was missing.
I wanted to install CWM, but I did it from within the Flashtool, rather than ABD then Flashtool from Terminal.
So, it ended up just sitting on the Sony screen. Not what I wanted. Tried to get it to play nice....nuda!
Therefore I have just finished flashing back the 10.1.1.A.1.253 DE Generic/Unbraded .tft file and it's rebooted nicely.
Now what I'm going to do is work a way to get the CWM back on there. I really want that to try and restore my ROM to the original factory and just use Root Delete to "hide" the update from my sight.
[SITUATION] Now resolved back to a working Xperia Z.
[SECRET] Use the Power+UP key combination for 10 seconds until you feel 3 consecutive vibrations. Download a Generic ROM. Install using Flashtool~!

This is bad advice: do not turn it back on or plug it in after water has gotten inside the phone. I killed it by trying to turn it back on right after i saw moist in the inside of the camera lens. It turned on for a few seconds and showed the xperia logo before turning off dead.
Do not risk short circuiting it. Let it dry for a while before you turn it on or plug it in.
Regardless, mine got replaced but I will not submerge it in water anymore.
Edit: just so you understand what I went through, I tried every single piece of advice that I could find to dry the inside. After a few weeks I just had to give up and take it to repairs.
Note: if the damage was caused by the back panel coming unglued I recommend to document this problem when you bring your phone in. It is a known problem but it helps with service centers that will go straight forward to blaming you for the water damage. I printed this whole thread and the links contained in here, put it in a folder and discussed it with the repair center.

Yes. Tried it. Also tried the dehumidifier christals. Nothing.
It all depends on the extent of the water damage but it does not really matter if you short circuited the phone before trying to dry it.

[Q] Xperia Z - Red LED and three vibrations on charger

Hey guys!
Today my Xperia Z (on .350) seemingly died. When not plugged in absolutely nothing works. When plugged in to the charger it goes in a red LED loop where it does the usual charging vibrate, then waits a few seconds, then vibrates three times. After that it shuts down and just starts again.
Does anyone have experience with this particular issue? I couldn't find anyone mentioning these exact conditions.
Cheers!
Ambroos

Did you tried pcc or sus?
Why you still on 350? It has a sudden death issue.

Yep, phone just doesn't do anything over USB, no fastboot, no flashboot, just the same as the charger.
I was on 350 because I work with Sony Mobile on a project and got my phone (a retail sample) from them. Update wasn't available and I didn't want to screw around with FTF's to avoid problems. We have a long weekend so I can't reach any of them 'till monday and would like to have a working phone by then.

If you have an external sd,remove it and try.

Tried, didn't help...

I'm having the same problem, red led loop with 3 vibrates once the phone gets power to it. it wont turn on or show anything from the screen. Before this happened, the back camera had dew on the inside and the screen was flickering quite a bit before this problem occurred. i've opened the back of the phone (removed glass cover) to make sure there was no moisture inside. i'm hopeing it only needs something replaced inside of it. any help on this issue would be muchly appreciated

I got this problem also anybody have a way to fix this?

have you tried to flash a ftf from flashtool?

[Q] Xperia Z wont stop vibrating

My Xperia Z started to act weird from two days ago, when it started to vibrate during all the time.
I restarted the phone,discharged the battery and recharged it again but it does not help me at all. It keeps vibrating even when the phone is turned off and it seems that it will never stop.
Did you guys had any similar issue?
Plzzz somebody help me:crying::crying::crying:

Did you tried a hard reset?(hold power and Vol Up at least 15 seconds)
And if i understand right, it vibrates too if you shut it down, or only from boot on?

I now that it seems crazy but the problem started in my pocket when the phone was together with my bio-metric passport for a couple of hours. Maybe it s caused from the chip of the passport?!
I want to share another fact with you:
Always before having this issue when I was pressing the phone from both sides with two fingers close to the menu button it starts vibrating but stops immediately after releasing it. I don't know if it happens to all Xperia Z mobile phones.

Doesn't happen on mine.
Maybe you should Send it to a Service Center or go to the shop where you bought it and ask for warranty. Did you Already tried to re-flash Stock Rom using FT?
Try flashing an old 4.1.1 one, it could be the NFC sensor. The downgrade will Also downgrade the NFC software. It may help.
If I should upload mine 4.1.1. ftf, just ask.

no, NFC does not interact with vibrator motor. That two devices is so separated
Sony must replace your phone in any reason. That's definitely sony fault.

Just had the same problem, My sony Z is a repaired one just over a month old. It is Always in a Leather Case. Just 15 min ago the Phone just started vibrating (thought it was a call) non stop. Turned the Phone off but didn't stop. Turned it on again but nothing changed.
meanwhile searched the web for solutions, only thing i could find that it was hardware related.
Since the Phone is little to big for my pocket i thought it could be from flexing the Phone or something like that. So i put it back in it's case, and put it flat on my hand and gave it a firm tap on the back with my other hand. The 2nd try was succesfull and the Phone stopped vibrating.
Checked if normal vibration still works and found no problems.
My experience with the latest Phones is getting worse with every model they (HTC / Sony) release. Feels like the phones suffer more and more from stupid (hardware) problems. Looks like the Urge of releasing a new model every half year is showing its flaws...

Mine vibrating too and getting worse!
The store guy told me it was the cover I had it in. Bollocks. The cover has been off for two weeks and still it vibrates! Seems to be worse if I charge it via a USB charger in my car. Related perhaps? I just tried the suggested holding down of power and volume and it has stopped vibrating. Fingers crossed! Glad I'm not the only one but need a fix

same thing here. my phone is vibrating RIGHT NOW!
my z3 is dual sim model the D6633. only 2 weeks old.
the phone first stop working on the touch screen. phone would not react to any finger. so when its locked, i can use the camera button to wake up and take pictures. still will not respond when i touch it.
then the phone getting warm at top area near the headphone.
so i google it how to turn off z3 with button, so i did, power+ volume
when phone turn back on, no screen. only a black screen with back lighting on. i can tell when i put phone right infront my eye.
then the phone start vibrate!!! none stop vibrate.
at this moment, i CAN turn off the phone with power+ volume but WON'T stop the vibrate.
really need a help, im in US and purchase this Z3 from NEWEGG and it is a DUAL SIM model, can i get warranty in SONY retail store????
GOD! why me

vibration problem
Hello,
I had the same problem.
Sony claims that there products are waterproof.
We as customers like that and want to try it out.
Maybe not in a swimming pool but at least clean it under de faucet.
That should be no problem, it is waterproof right!!!
After a while this vibration problem occur to your device.
Because none of these solutions help to stop this problem I decide to open my Xperia Z2.
My surprise was that I saw very small tracks of water inside!
Then I put it in the hot sun while it was open en the problem disappeared.
My conclusion:
It is NOT waterproof en a small short circuit causes the vibration problem.

[Q] Phone keeps shutting down. Three vibrations

My Xperia Sp brought on contract from EE was working fine until earlier this week. The phone had 30% charge left when the phone shutdown. When i went to turn it back on, the phone vibrated three times and nothing happened. I tried plugging the phone into the mains and charging but the phone kept vibrating in a series of three vibrations. I tried the common answer to any problem with this phone and held the power off button at the back in and pressed the on button but this didn't work. I have also tried other combos such as the one Sony emailed me which was to hold power up followed by the on button but this did not work. The next day the phone magically turned on and i used this as an opportunity to back up my data off the internal memory and re-flash the stock android 4.3(12.1.A.0.266). The phone lasted a couple of hours but then did the same as before and kept vibrating. I left the phone a bit and when i got it to power on again, i flashed android 4.1.2 (12.0.A.2.245) onto the phone. The phone worked for only an hour before shutting down again and not turning on. I have tried various shops in my town, the first said they think it is software but they couldn't fix it, the second said it is a battery issue but they would have to order in a new battery and I also tried EE who refused to even look at it as my contract didn't come with warranty. Sony have emailed me back asking me to send it off to them, but i have no proof of purchase so that is out of the question. I have also searched Google for hours trying to find a solution but the only on that sounded remotely like my issue was apparently a sleep problem, but this is clearly not the case. I would really appreciate any help anyone can give to me about this issue. Thanks in advance to any help given

Thanks for the quick reply. I have noticed that the button looks a bit damaged but i had no idea this could be the problem. I will see if i can get it repaired.

If you bought it recently just take it back in warranty. Have you ever used that off button? Because my friend had xperia z ultra and he used it ONCE and it broke and sony didnt give him warranty
Sorry for my english, im doing my best

I brought the phone last october after my first sp(red) stopped charging as the usb port got damaged. I have used that button loads of times before using pens, pins and even a ds stylus to use it. The slight cover on that button has gone as a result.
