I've done much worse things to my Z5 and I've Always been able to unbrick it, so I'm fairly sure your phone will arise from the dead, after being charged for several hours. Good luck my friend ;)
[Xperia Z5 General] XperiassinceZ1:
I updated also my z5 last night. I was going to sleep and I set the timer to start updating 5am. The phone had 3am like 50% power and was plugged in to a powerbank with nearl 100% power (13000mAh) but in the morning when I woke up, the power bank was off (auto offs when not charging) and phone was dead. I plugged phone and had to click the power bank to start charging (usually it charges automatically when i plug in). Now the red light just flashes while its on powerbank/computer/power cable and if I press volume flashing stops, If I press power it runs only red. Seems like this ****ed up firmware update somehow 1) drained all my battery which should be nearly 100% at that 5am AND 2) while updating it disconnected somehow the powerbank.

Im afraid this thing is ****ed up as it has powered off while firmware was being updated. I have now charged it for nearly 3 hours and no response, only red light blinking. Great to pay for a phone 850€ and not even after year it does **** like this (the powerbank always stays on even with 100% power and charges, but this somehow under update the phone rejected the given current and the powerbank turned off AND didnt auto-turn-on).
[Xperia Z5 General] koekoek91:
Plug it in a normal wallcharger, and leave it alone for a few hours. It could be necessary to check every now and then if it's still charging (led blinking) or on.

I hope this works. I tried before to connect phone with pc to use sony's software to fix: it told me to power off, wait 5 seconds and then hold volume- and connect usb, but it didnt connect phone. I don't know was it even ever on or can it power off now if it is on.

For now I have also tried pressing power/ vol+ / vol- / power & vol+ / power & vol- for at least 10 seconds each and i tried pressing reset for like 15 seconds after removing sim card but nothing happends.

Only thing I'm concerned about is losing all data. Do u happen to know is there a chance getting backups anymore or installing software without losing everything or have I already lost everything as I have pressed restard and tried this Sony's fixing software?:confused: I have all my pictures, videos and notes on internal memory and damn if I lose it all..:mad:
[Xperia Z5 General] koekoek91:
Im not sure but I think your files should still be there. Unless you flash a new firmware over it.

Copy files to an external SD or pc before flashing again.

But for now, your biggest concern I think should be getting the device charged up ;)
[Xperia Z5 General] XperiassinceZ1:
reply

I'll wait and try. Thanks for the help so far. :) So there is a chance of getting it started "normally" after its being charged?

To copy the files I need the phone to operate, right? So if the last firmware update messed stuff up and the phone stays brick I'll have to reinstall it and probably lose it all?
[Xperia Z5 General] koekoek91:
I bet 99% sure it will get recognized by your pc again after charge. Just give it some time and keep an eye on the led every half hour or so if u can to see if it still flashes or stays on. If it keeps flashing just be patient and wait, maybe between waiting for the heck of it plug it to you pc and hope for the best. But ice had this so many times, I'm sure it will be working in a while :)
[Xperia Z5 General] XperiassinceZ1:
I've been charging it for like 7 hours now and still blinking red :rolleyes:

I have 2 exact same sony chargers, one on z5 and another on powerbank: the one charging powerbank is hot but the another one is barely warm. I don't know is it even charging the z5 and it has been so long plugged in computer/powerbank/charger that it should be already full? Still no response..

or try switch the chargers, if u havent already? I dont know what else I could tell u to try.

You dont have a recovery like twrp installed do you? sorry if u already said this before..
[Xperia Z5 General] XperiassinceZ1:
I switched chargers and now the the the phone charging one cools and other one warms up. I don't have any backups. Ill try to connect again PC but isn't it the way to lose data?

I haven't try flashtool, if it should mean "external programs", only Sony's own program. Should I try some flash tool? I've heard I could lose warranty.

added:

Ok I tried again Sony Xpreia Companion and it's useless because it wont connect and the only possibility seems to be fixing firmware with it which also deletes all files. Resetting wont help neither, and still I worry about those files so I don't want to do the forced 120 seconds reset. Is there a chance that it could charge the phone for like 10 hours? Only thing I care about is now my files (pictures + videos mainly, but text messages as notes would be nice to save too), because total factory reset shouldn't be a problem anyways?
[Xperia Z5 General] koekoek91:
Usually I think most people just flash the latest firmware to fix their bricked device, if they dont have a custom recovery.

But there are more things you can do, but not before it gets recognized. Maybe you should make a seperate thread in the troubleshooting forum for z5.

Maybe more people will bring idea's.

Personally what I think I would do is just leave the device alone for a night and try again fresh the next day.

One more thnig I have read about is that draining the device battery completely also could help, but I havent tried this before or have any experience with this.

You could do this by trying to tape the power button once its pressed in, but I dont know if this works and will stick with the button pressed in, or if there is a better way.

Im just shooting idea's but im pretty much out of idea's i think.

If i remember more ill post it though:fingers-crossed:

---------- Post added at 05:51 PM ---------- Previous post was at 04:57 PM ----------

If you did a backup in the phone itself you might be lucky and will be able to restore most things next time you have flashed the latest firmware.

You should run a back up every now and then, but im sure you will from now on if u will be able to fix your phone.

Search google for similar cases to yours and see ifthey got solved. Or search here on XDA, and definetly post a thread here and ask for help: http://xdaforums.com/xperia-z5/help

Anyway,s im out of idea's im sorry. Like I said post in the help and trouble shooting section and ask for help.

Leave your phone charging for a whole night, and google searh for flashtool from [MENTION=2807379]Androxyde[/MENTION] and try getting it to recognize your phone.

This is all I have left to say for now. Flashtool can probably help you, but I dont have time to explain every step you need to do, but google is your friend ;)

Sorry I couldn't help more...

Good luck!:fingers-crossed:
[Xperia Z5 General] XperiassinceZ1:
Thank you very much for your help. Nice to have ppl helping and making some effort to help strangers. :)

I've posted a new thread to z5 premium - trouble shooting. Lets see how this ends up. And in case this gets solved and someone has the same problem, here is a link to that thread http://xdaforums.com/z5-premium/help/z5-premium-bricked-red-light-flashing-t3481798

I just checked the phone and still blinks red but the charger feels even more cooler, a bit warmer just than room temperature. :confused: I guess that rubber band power on thing wont help as I have had my z1 on for weeks when it had a broken screen and it was logged in without sim.
[Xperia Z5 General] langeveld024:
Just unplug, hold power button and volume UP button until it vibrates 3 times quickly.

Then u can connect in flashmode and fastboot again or u can try powering up first.
[Xperia Z5 General] koekoek91:
This doesn't always just simply works sadly[emoji14]
[Xperia Z5 General] langeveld024:
Not when u really bricked it.

But I see lot of people lately "brick" their phone with official firmwares but it's most cases just hanging on boot.
[Xperia Z5 General] Pandemic:
Simply flash an ftf with flashtool and update again, you can blaim better yourself instead of Sony because its not a smart idea to update when you Z5 is connected with a powerbank, use normal charger in a wall next time.
[Xperia Z5 General] 4Strings:
Can't really flash an FTF when the device won't boot or be detected by Flashtool, can we? ;)
[Xperia Z5 General] 4Strings:
OK. So I got my phone back from the repair shop and, of course, they didn't manage to fix it (at least they didn't charge me, right?). So I've decided to take matters into my own hands before shipping the damn thing to Singapore.

Luckily, I have at work access to a variable DC power supply with digital readouts of output voltage and current, and so I was able to do a bit of testing:

I set the power supply to output 5.1 volts at the maximum possible current and spliced a USB cable's positive and negative power pins (the red and black wires in the cable) into the PSU. After plugging in the Z5, I observed that, while the phone is charging (red LED blinking) it's only charging at a rate of 75mA. I plugged in my sister's old HTC M8 (she loaned it to me until I either fix my Z5 or get a new phone) and it charges at a rate of 500mA, so I know it's not the power supply.

With the Z5 plugged in, after waiting about ten minutes, I tried to press and hold the off button next to the SIM tray for 120 seconds and the Z5 gave a sign of life by vibrating three times! But it wouldn't do it again whether it was plugged in or not, meaning that what little power the battery managed to store was completely depleted by the vibration motor.

This means that the phone is NOT permanently dead, but that the battery somehow got so depleted that it only charges VERY slowly. I did the math and since the battery has a capacity of 2900mA, at a charging rate of 75mA (with a 20% efficiency loss) the battery should be full in about 45 hours... :/

It's not an immediate solution, but at least it gives some hope of getting the phone back (maybe even without any data loss).

While I know that most people don't have access to variable power supplies, this should also work with a regular (good quality) charger. What this means for anyone else that has this happen to is that (maybe) you just need to leave the phone undisturbed for about two days and maybe, JUST MAYBE, it will come back.

I'll leave my Z5 connected to the power supply at work until tomorrow morning and hopefully it will be 50% charged by then and turn on. I'll post an update with what I find.

Cheers,

[Xperia Z5 General] koekoek91:
Very useful post.

Good job and I'll read tomorrow about your progress [emoji1]
[Xperia Z5 General] xasbo:
That's not how Li-poly charging works. Below a certain battery cell voltage, the charging circuit only allows a very low current to slowly add energy back to the cell without damaging it. This is basically a recovery mode, and the charging circuits are designed to never let you get into this state in the first place normally. Sometimes, though, it's possible to - through a combination of heat and discharge rate - blow past the safety limits that are in place and either kill the cell, or come close to it. Based on the scenario you described - high discharge with no charging, this is probably what you've done. But, it's probably salvageable, since you did get the vibe motors to go off.

The absolute best thing you can do is to set up 500 mA current limit and a 5.25 Vdc over-voltage protection settings, then leave the phone be for another 24h. If you have any chance of saving the battery, it will be by doing this. It may come back after a few hours, it may take another day, it might not come back.
[Xperia Z5 General] 4Strings:
Thanks! That's what I guessed happened. Though I still don't understand how installing an OTA while charging could completely deplete the battery past its minimum limit like that...

I checked on my setup this evening/earlier tonight and noticed that now the charging current is sitting at about 76 or 77 mA, but will occasionally jump to 96, 182, or 210 mA for about a second... It's not happening in connection to the LED flashing, and it's not happening at regular intervals (at least as far as I could tell), so I don't really know why it's happening now, but I'm hopeful that it means that the battery is nearing the minimum limit and is periodically trying to charge at a faster rate.

I'll check on it again in the morning when I get to work and post an update if anything changes.

[Xperia Z5 General] YasuHamed:
the behavior you are describing is similar to what happend with me in 2013 with my LT36H (Xperia Ion)

it got BRICKED while flashing, i had to DRAIN the battery by pressing the volume key for 12 hrs ( used rubber band trick) then for next day or so i kept the ion on wall charger (power charger) until finally it showed red led light! connected then to flashmode and reflashed it!

your phone will come back to life

what is astonishing for me is WHAT EXACTLY the service center did ? didn't they just dismantle the batter and reconnect it after some time? or what?

why we generally have xperias bricked because of non removable battery. the kernal booting get stuck in the memory and there is no way to shutdown or reboot unless your battery drains and/or u dismantle it
[Xperia Z5 General] koekoek91:
So your ion did not give any led at first when plugged into charger (before you drained the battery)?

Any idea on whats the best way to go when its flashing red light after its bricked,. let it charge, or just drain it and try recharge?

Im trying to help [MENTION=7800112]XperiassinceZ1[/MENTION] with his bricked z5 premium.

I told to let it charge for a whole night, but after charging for about 10 hours still just blinking red he says.

Im wondering if he should let it charge for even longer, or drain the battery first.

I've had several times the exact same issue with my Xperia Z5 (E6653), also right after bricking gave me red flashing led when plugged into a wall charger.

For me, letting it charge for a night (about 6-8 hours) has everytime moved my flashing red light to ongoing red light and then connecting it to pc with usb + volume down brought me in to flashmode.

So now im writing this, I think he just needs to let it charge for even longer.

Any thoughts about this? :p
[Xperia Z5 General] 4Strings:
So what you're saying is that the reason the phone is charging so slowly is not because the battery is empty, but because it's actually full and just the phone THINKS it's empty?

If that's the case, in need to disconnect it from the charger, drain the battery by holding down the power button for 12 hours (so that the battery level matches what the phone is expecting), and THEN charge it, and if that doesn't work I need to open the phone and disconnect and reconnect the battery?

I took the phone to a general phone repair shop, not a certified Sony service center (there aren't many of them in the U.S.), so I doubt they did anything with the phone...

I managed to get a list from Sony of actually certified service centers in my area, so if both the long-range and the discharge-then-charge methods don't work, I'll start going through the list and see if any of them will open the phone and disconnect/reconnect the battery without voiding my warranty. If none of them are willing, I'll just follow the iFixIt guide and do it myself...

Cheers,

Just be aware that the waterproofing might be void by opening the case to get to battery. Not even certified Sony centers have a solution for this, as far as I know...

it reads only fat32 format

if its exfat , it wont
[Xperia Z5 General] 4Strings:
I know. But unfortunately, if it's the only option, then there's really nothing I can do about it...

I checked online, and since Sony SG said that I'll need to pay all duties/taxes plus shipping to and from Singapore, it'll probably cost me about $300US. So my warranty is basically worth s*** since sending the phone will cost almost as much as a new Z5...

So I've really got nothing to lose and if I do manage to resurrect the phone there's nothing stopping me from unlocking the bootloader and rooting... ?
[Xperia Z5 General] 4Strings:
UPDATE:

So I checked on the phone this morning and it was still charging at 75 mA with the occasional fluctuation to ~200 mA, but the phone still wouldn't boot...

So I decided to try YasuHamed 's idea and unplugged the phone and rubber-banded the power button for about ten minutes. After the ten minutes, I plugged the phone back in and lo-and-behold, it was charging at 487 mA! After about five minutes it dropped back to 75 mA, so it seems like the battery is full but the firmware/software thinks that the battery is empty...

I'll try leaving the power button pressed for 12-24 hours and then try to charge it again and see what happens...

Well there's a couple things you can do:

Flash a custom kernel and a recovery to format it to the correct format.

But if you have an sd cardreader I would take it out of your phone, plug it to your PC and copy everything thats on the sd card to a temporary folder on your PC.

Then format the sd card using your computer and copy back the content.

Hope this helps.

[Xperia Z5 General] koekoek91:
You're on latest .305 firmware with sony stock kernel? Or diferent kernel? Maybe I misunderstood before.

With stock sony kernel fat32 should work.

If you're on a custom kernel, if this is the case then you could flash twrp recovery via minimal adb and fastboot tool.

Then in twrp you could try to format to fat32.

[Xperia Z5 General] YasuHamed:
If I were you, i would have tried DRAINING the BATTERY by volume button trick, kept on charge for days until the RED LED comes and then tried reconnecting it to fastTool.

its over all problem in the world with sony local dealers that they are only representing Sony Japan in USA / EU / MENA but they have very limited knowledge to fix Sony Devices! and usually it goes either to Singapore or Japan etc, takes months and you have to bare all the charges!

The reason for several iterations of the same firmware seems to be the messed up volume control settings (upon pressing vol up/down keys in home screen mode there were no options to adjust all three sounds). At least NOBA wise, latest version fixes it.

yes rubber band you xperia in a way that it keep pressing VOLUME UP button! the battery should drain over few hours! BUT if it was not fully charged at the time of getting bricked then it might be sooner than your expections!

later try charging for hours until u see RAY OF LIGHT :P (red LED)

then try unplugging and try connecting to flashmode

[Xperia Z5 General] piponxs:
Its fine im not complete noob. So from beginning i was on normal .253, Then I decided to flash some custom roms, I unlocked BL, rooted and tried many different custom roms, after some time I saw that my fingerprint sensor isnt working "fingerprint hardware not availible" error. So i decided to find a solution because Im really using it a lot.In that time .305 fw arrived so I tried with flasing it via flashtool but still nothing error is still there, something is messed with ub because more and more people report this issue after unlocking bl. Then I saw thread rooted .305 kernel for dual z5 http://xdaforums.com/xperia-z5/general/mm-firmware-z5-dual-e6683-32-2-0-305-t3477378 so I took a risk and flashed it via fastboot over .305 fw, booted up everything is fine, no errors on fingerprint sensor but now phone doesnt read sd card. Maybe because that rooted kernel is for dual z5 and Im on E6653
[Xperia Z5 General] koekoek91:
Okay now I understand better.

Well... I have never tried flashing a kernel for dual Z5 on my E6653, so I wouldn't know about that. I wouldn't recommend it.

Can you try flashing twrp recovery and see if you can format your sd card from there to fat32?

EDIT: I just see your post on the the thread you linked that you downloaded the kernel from.....

You already have acces to twrp? Under advanced, go to partition SD card and try to format it to either fat32, or if that doesn't fix it try formatting it to ext4 format.
