Xperia Z1 won't boot? Last resort try this. - Xperia Z1 Q&A, Help & Troubleshooting

I know this has been a common problem among Z1 owners. I recently purchased a Z1 off craigslist and it had been working for 3 days. Today I had powered down my phone and attempted to turn it on. To my surprise the phone would not turn on, and would not display any sort of charge indication when plugged it (LED, screen, etc). I had tried hard resetting it and all the common troubleshooting with no luck until I decided to remove the back cover.
- (With caution) Remove the back cover on your Z1 (Using heat, suction cup, and something to pry it up with).
- Once you have done that remove the 9 screws holding down the shell then (very carefully remove the shell).
- Once you have done that remove the battery terminal so the battery is disconnected.
- With the battery disconnected plug in your z1 and you should see the phone LED blink and screen flash "SONY".
- Now remove the charger and re-connect your battery.
- Hold the power button down and volume up until the phone resets
I hope this worked for you like it did for me.
PS make sure to replace the back cover adhesive as your phone is NO LONGER WATERPROOF.

I'm thinking to do the same thing as it helped many people. Just curious, was your phone Z1 completely dead? NO LED light at all?
Mine shows no sign of life so far, no LED, nothing.

How long did you leave it plugged in for?
When mine got bricked, it took about 24 hrs. before the red led started blinking.
Just wondering if it's actually the same problem.

24 hrs to charg by wall charger ?

This method didnt work for me, I'll have it repaired (then sell it) soon but warranty is void. Either way I wasnt able to claim warranty as I bought it from local classifieds without receipt of purchase. At the mean time bought another Z1 for $440 with no yellow tint issue.

This method didnt work for me, I have to change a new main broad。

[Q] Xperia Z, Hard Brick after battery drained

Hello, just about to pull the trigger on a new xperia ZU, but i wanted to see if anyone had any tricks for me to try on my Xperia Z. I was running near the latest CM 10.2 without issues for awhile now. Last night while i was bowling the battery died( nothing new happens all the time to me ). When i returned home i hooked it up to the wall charger for about 30 minutes, came back and still no life. I have tried multiple chargers and multiple cables with no luck. Device has been plugged into power all night and all day so far. When i attempt to power on with it unplugged i get the 3 pulse red led. When i hit the power button with it plugged in all i get is a solid red LED. Nothing more, nothing less. Cant get into recovery or anything. Most of the time a hard brick involves a mis flash or something along those lines....any idea what could have happened to mine?

It might be the battery...
Its not advisable to full discharge the battery but it seems that u did it a few times..
The battery might not take any charge as the red indicator means low battery...
Tried a new battery,i know after removing the rear panel n say good bye to water resistance but is worth a try...
Or u can send it to me for free if u wanted to throw it away...
hope this helps...
Had the same thing happen
I had the same thing happen to me. From what I read trying to troubleshoot it seems like the Xperia phones in general can take 30 minutes + after a full battery drain to even register that a charger is connected. I would try just connecting it to the Sony charger for a few hours and see if that works.
There is also a tip about holding down the power button when plugging in the USB charger and continuing to hold the power button until the phone turns on. Unfortunately, can not find the original post right now. EDIT: Found it. http://talk.sonymobile.com/t5/Xperia-T-TX/Xperia-T-Wont-Charge-Turn-On/td-p/252686/page/4
In my case the red light would not even come on when the charger was connected but would come on if I held the power button down while connecting the charger. After I did this for a couple minutes the phone booted and has charged normally ever since.
So its a mixed bag. Try just charging it for a while on the Sony charger or wall charger (not USB). Or try the power button trick.
Lesson I learned is I will not let the battery completely drain again.
Ahhahha it came back alive! I had tried pretty much every trick that has been suggested and it just wouldn't charge or start to boot. Left it on the main charger again last night and still no luck this morning. Again I decided to plug it into my computer's usb port( I did this multiple times already ) and I hit the power button, a backlight came on!!! and then sure enough there was the free xperia logo! I have no idea why it finally decided to power on, but its showing 1% battery so it was truly not charging any of the times it was left on a charger, computer or mains. Thanks for the responses guys, I appreciate it!
I know this thread is pretty old. But I'm having the same trouble. Xperia Z got bricked after battery drain. It wont recognize charging, i kept it on charge two nights in a row now. It did show a red LED while charging for some time and nothing else, but now its back to being stone dead. tried holding down the power button trick, didnt budge. I thought you can only hardbrick it by doing a wrong flash/update. dont know what happened in this case. is there anything else I should try or just take it to a shop and ask to change the battery?

man, try with a new battery, here in my country cost 14 euro . Or go in a service or buy a multimeter and measure the current of ur battery. Normal they from service will give u electrosock to bring it to life. And if will dont work i think u must sell it on piece and buy another
Same problem with my Z3 Compact: one day phone became hot and started to discharge rapidly and when battery became empty, cannot charge and cannot boot, only red LED is ON. I changed the battery and phone booted again. BUT when battery was discharged completely, phone cannot boot again, only red LED is on when trying to charge.
Looks like something wrong with motherboard is happening...
Xperia ZL battery completely drained, not starting up
I know this thread is old one, but I am having issue with my Xperia ZL. Its battery drained to zero and then whenever I plug in my charger, screen starts, Xperia Logo pops up, red light also starts and suddenly everything goes off. This goes on and on infinite number of times. Phone heats up but it doesn't turn on. I had issue with my battery, a couple of months back, so I replaced it with new one. If anybody has any solution about this, please let me know.

[Q] Phone bricked, red led flash twice

So I have my Z1 for 5 weeks now and I used some times in my pool in home to take some pictures, I've always been cautious with the flaps and everything, I even immerse it in rice overnight when I use it in water just to be safe. Today I used normally, took some pics with girlfriend, everything worked great, after taking the pictures I left it on the table and about 1 hour later I tried to use it and it was blank (me and the phone were completely dry by that time). If I connect to wall charger or USB the led flash red twice and then blanks. I'll leave overnight charging now but I have no idea what to do. Tried turning off using the red thingy, turning on holding volume up or down but nothing works.
Can anyone help or I will have to send it for warranty?
Oh, and I checked and not a single drop of water entered the phone (apparently).

You seem a little paranoid about water, if water had messed your phone up you probably wouldn't even get a red flashing light (as the motherboard would be fried) so you don't need to worry about water damage.
Firstly, presume everything you had on your phone is now gone. Sorry!
Follow these simple steps:
Press & hold the power button and volume up until it vibrates 3 times, then you can go ahead and try to turn it on. Quote me when you reply so I can see it.
Could you also plug it in to your laptop, does the computer read that a device is being connected?
If that doesn't work, we'll try some other stuff and explore some threads! Lots of links for bricked phones. Sounds like it's bricked..

Good thing it's not water!
Did it for over a minute and nothing happens. I've tried that earlier too.
Plugging it on the PC makes the sound of device connected, the red light turns on for a while (about 2 or 3 seconds, no blinking) and then it turns off with the sound of device disconnected.

Have you tried plugging it in with the Sony software? If you have that downloaded..
You'll need to do some research... http://forum.xda-developers.com/sitesearch.php?q=bricked phone

Have you checked the charger? Try putting it on charge for a few hours then try everything again. Do you have more than 1 charging cable? try the different cable.

I've already tried some solutions there and will try others now.
PC Companion won't detect phone. Same with Update Service.
Worst case I'll leave it charging for 12 hours. Thanks for the help, I'll come back later with some feedback. I'll probably get in touch with warranty tomorrow morning.
I'm experience this problem with xperia z after washed the phone. I thought is water damage so I'm just leave my phone. Buy new xperia Z1.... But after 1 month i check back my phone surprise!!!! Is revive again....
Almost 12 hours on wall charger and no sign of life. Still just blink twice the red notification light.

Try all the steps again, otherwise I really not sure what's happened. Some people report days later it comes back on, etc. Hopefully someone else may have an insight to what's happened, but personally I don't think your phone is buggered.
Has this been resolved? I just ran into a similar problem with my week old Xperia Z1 Compact. It was working fine until one afternoon, it was hot and wouldn't turn on. Got the blinking red lights and won't charge. Also won't do anything with the Power and Volume+ Combination.

[Q] Hardbricked handset whilst charging overnight

I've recently been experiencing some charging issues with the handset taking forever to charge, the latest charge was taking well over 15 minutes increase 1%. I tried various chargers, including a brand new original one (the one in the box).
Well, last night I put the phone on charge with the handset turned off around 2am, woke up around midday today and the handset was showing the green LED, so it was almost, or fully, charged. Went downstairs to have a cup of coffee and came back ten minutes later to find the LED off. Tried turning the phone on and nothing happened. Tried the reset combination and the red button under the SIM flap, nothing, tried connecting to SEUS, nothing. Tried connecting to Flashtool, nothing. I left the phone on charge for another hour and tried the same things again, nothing.
No lights, no vibrations, no screen activity. The phone isn't even getting warm like it normally does on charge (confirmed that with another charger)
My girlfriend said that whilst I was downstairs she did take it off charge and put it back on charge straight away when it wouldn't wake up BUT she wasn't sure if she put the charger back on the right way (the magnetic one) however the pins don't actually touch if the plug is the wrong way round as the pin towards the bottom of the phone is offset slightly so I don't believe it has shorted.
So great, my almost new Z1 is now a paperweight. Sony won't touch the handset as the back glass has a small crack in so they just spout off about water damage. The phone has never been near water, let alone in it.
C6903 on 757 firmware, bootloader relocked and non rooted. No nasty apps installed and basically running stock,
Anyone have any ideas? I'm resurrecting my old BB for the time being.
I bet its been shorted
Leave it on mains charger for 24 hours

That's what I'm thinking. The design of the dosk pins should prevent that, but apparently it doesn't!
As probably there is stripes to check if water was inside I will exclude that. Also the magnetic connector have his way to plug so is close to impossible to revert it, hardly if you try maybe it will, but I did many time and nothing happened. At last I think you girlfriend mess up with you phone and now she now don't remember because she knows you will be furious...LOL...
BTW, I will press Sony to take look at it. They don't have to replace the cracked glass, they have to check where is the problem.

As you say, none of the water indicators (if I'm actually looking in the right place) are a different colour to normal. The dock pin is offset to one side slightly, it can be seen if you look closely so you are right, it really shouldn't have damaged the handset.
She isn't even sure if she did plug it back in! She was half asleep so I don't know lol
Sony will be getting some nasty words in a letter if they fail to do anything. I don't care about the glass, it doesn't bother me, as long as the phone works,

[Q] Xperia Z does not turn on.

Hello everyone,
In the past week, I have decided to sell off my Nexus 4, and I went on to buy a new cheap unlocked 40$ android phone and a used water damaged Xperia Z.
I had just got the Xperia Z a few hours ago, and the guy who I bought the Z from, said a bit of water leaked into the phone about 2 weeks ago, and ever since then the phone does not turn on.
So far I have pretty much disassembled the whole thing, and noticed that all three water indicator stickers at the ports have turned red.
But I seriously cant find any water, damage or corrosion on the phone's connectors, internal frame, battery connectors, anywhere.
I guess only a few drops has entered the phone and over time the water evaporated.
Now after drying the internal components in the sun, and using 70% isopropyl wipes (I looked everywhere for 99% isopeopyl Alcohol liquid, I cant find them everywhere) I wiped it over the phone's motherboard and then used a toothbrush to remove any dirt or corrosion building up in the board.
Now the thing is that the phone does not do anything when I plug in the charger.
But when I remove the battery, and plug in the charger, and press the power button, the phone's LED blinks red for about half a second, then vibrates once and then a blue LED light comes and stays on. However nothing comes up on the screen.
I tried the Power button and Vol.Up button, but it does not do anything.
The Z's battery seems fine, as I tried it out on my Xperia C and it works perfectly there.
And I tried the Xperia C's battery on the Z. Same thing no response from the phone
What should I do?
I guess look around or a 99% alcohol solution and properly wash the Z's motherboard?
Or is this some sort of a software issue?
Any help will be appreciated.
Thanks!

To me it rather looks like the seller modified the software and hard bricked the device... My Xperia T had the same sympoms when it was hard bricked....

Every fault is not caused by a faulty battery. I know you fixed your phone with a replacement battery, but that is not the solution to everything.
If you had read his post properly, you would see the battery powers another device just fine. A shorted battery would surely not function at all.

Well today, I bought some distilled water and washed the phones motherboard with a toothbrush to displace any particles left on the board.
Now When I plug in the charger (with out the battery, as the phone does nothing with the battery plugged in) the phones LED blinks red and the phone vibrates once. It then goes on to repeat this process over and over again.
But my computer kinda detects my phone, as it tries to install the phones drivers. If I remember correctly the devices name on my computer is 'S1 FlashBoot'
But for the computer and Sony PC Companion to detect my phone, I have to remove the battery ribbon to let the phone start up on USB power, and then reinsert the battery ribbon when the phone vibrates and flashes its LED once, and then I have to remove the Button ribbon since, for some reason if the button ribbon and the battery ribbon is connected at the same time the phone shuts off.
Sony's PC software detects my phone, but since I cant press the power button due to the removal of the button ribbon from the motherboard, I cant repair my phone using the software.
Maybe theres something wrong with the power button/ribbon is having a few issues?
I also found some corrosion bottom right hand corner under the network antenna, and a severely corroded 3 segment ribbon, where 2 out of 3 segments were non functional due to corrosion,. As I tried to open the connector, I sneezed and accidentally ripped it.
Dammit.
It didn't work before I ripped it, so I wonder if I somehow fix this ribbon would it help solve a few of the above issues with my phone?
What does this small dinky ribbon do, anyways?

Found this post through google while looking for a solution for my Xperia Z.
My first experia also had the same problem, sort of. The battery would jump from 90% to 60%, then 73%, then 20%, then 71% and so forth.
I decided to update the system software, to which it turned off during the process. The OS became faulty, and it rebooted all the time, showing a weak red light, then a strong red light, turn on, turn off and so on. The authorized service replaced my battery, but I guess that's not your problem in this case, and I doubt it that it's a faulty OS. Because even with a faulty OS, it would atleast show the Sony or Xperia logo.
Now I have the same starting issues and I blame the ribbons I guess, since when I press it the right way, it suddenly accepts charge and boots up. Replace the ribbons, and you might be fine. Guess there's some short circuit.

Xperia T - stock, not rooted potentially reversed USB connection, now won't switch on

Hi
I’m wondering if anybody has any advice regarding my problem. I have looked here and tried what has been suggested.
My stock, never rooted, never flashed, Xperia T (think it was Android 4.3 but can’t now check, the latest Sony rolled out) was working fine until yesterday. I was on a plane and noticed it had 20% battery life left so I plugged it into the onboard USB port. The problem is I think I hay have plugged the cable into the port the work way round – not the connection on the phone, but the actual USB socket. This should be impossible but somebody obviously had broken the port and it turned out the cable could be plugged in both ways! (I don’t know if it was plugged in the wrong way round but is the only thing that could possible explain the sudden death.)
Could this have bricked it? I suddenly couldn’t get a red light to show charging and holding down power on and volume up or down does nothing. I tried charging overnight via a wall socket when I got home but the result is still the same. Just a black screen and no sign of life. I have also tried plugging it into a computer with Sony’s PC Companion but as the phone is not ‘on’, it can’t be found.
Does anybody have any advice where to go from here? I’m more concerned about some recent data from holiday on the phone than the actual handset itself. If the phone is dead, is there any way to read the internal memory?
Thanks
Try this: Unplug the charger, press the power button. The phone won’t power up because there is no charge left in the battery. But press the power button along and while doing so, connect the charger without releasing the button. Now, you will probably see the red light. Please don’t take off your finger from the power button for around 1 to 2 minutes when the red light for charging will glow continuously. If you feel tired holding it, you can try sticking a tape on it in it’s pressed mode. Once you are sure that the phone is now charging the battery again(red light keeps glowing even after the power button is released) kindly wait for 5 to 10 minutes or may be more before you press the power button again to power the phone up. Now the phone will be up and running
If that doesnt work maybe ur battery is dead or usb port broken
Thanks for the advice. I gave that a go after trying a 24h wall charge and not touching it (which did nothing).
So, I held the power down, plugged it in but nothing. I held it down for around 5 minutes both manually and then repeated the process using the rubber band trick to keep the button held down but no red light ever came on. I think I’m going to try a new battery as I genuinely see that I have nothing to lose as I doubt it will be possible for anybody to recovery data given as the phone can’t be switched on so if I break it further I’m in no worse position!
Thanks again for trying to help though!:good:
When I got my xperia t it was in described condition. I also tried everything (rubberband trick and so on) but the only thing working was to open it and pull and put in again the plug of the battery. After that it booted immediately and I got this sleep-of-death-thing nearly every day... Since I soldered the battery as described in this Topic it happens only ~once a week. Good luck!
SOLVED! In preparation for the new battery arriving, I decided to take the back cover off. I unhooked the top battery connector and decided to connect it back up again, just to see if it did anything. Plugged in the charger and a red light came on straight away! I let it charge for a good couple of hours and switched it on – not as easy without the case attached – and it worked. I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!

I’m so frustrated with it being such a simple issue as needing to disconnect the battery but even more frustrated with the design that it is meant to be a ‘sealed’ unit with a non-removable battery. I used to often need to disconnect my old Omnia II battery to restart it but that was a simple case of cover off, remove battery, replace battery , put cover back on, not the creaky, back cover fear of cracking exercise of yesterday. Still it’s working now and hopefully life in the old phone yet!
