Hello XDA family
So, i'll start from the beginning of my issues with my xperia Z2, allmost two weeks of reasearch but nothing. I bought this phone preused and with broken digitizer, fixed everything and turned it on, booted up and everything was fine. Phone offered update wich i did and it was the beginning of my troubles. Boot loop was first thing, and few other things wich lead me into buying new genuine battery. I literally spent a day to get out of boot loop by disconnecting the battery, tried to reset and all sorts of thing and still don't know which of those many things actually worked but i got it booted up finally.
So yesterday i took it out of the box again and thought to update it to latest 5.1.1 Lollipop via wifi because i can't get phone into flashmode, so while installing update (android logo with blue loading line) my phone turned off. I turned it on again and same thing, android logo with blue loading line half done and turned off, and again and again. Finally disconnected the battery, connected usb cable to the wall charger, connected battery and red light poped on, so i let phone to charge, after few hours i turned my phone ON and voila, somehow i got latest android installed.. go figure.
When i bought this phone the rear camera didn't work, i saw the icons but didn't take any picture. Did cache clear and other tricks i found from google but nothing works, im not sure but i guess this issue came when last owner updated it from kitkat to lollipop.
So heres my biggest problem, to downgrade z2 to kitkat i need to flash it, but i can't..
When phone is on my pc will recognize it.
When power + VolDown, green led pops on (flashmode) and after few secons i get usb device not recognized. (Tryied some tricks that i found from google, no succsess)
When power + VolUp, blue led pops on (fastboot mode) and flashtool is actually connecting with the phone like it's suppose to be.
Im using Flashtool Version 0.9.19.8 and all necessary drivers are installed, included sony ones. I also Tried different usb ports and different pc, same thing.

Hello i have recently updated my ROM but sadly something happened with my service, it just said "no service" and i wasn't able to receive or take any calls so i installed this rom again from the recovery, and then when i rebooted this device, it suddenly stopped on the green goblin logo loading screen and my device was unrecognized by a PC, recovery didn't work... so i tried a RoFUSiON which can install a rom through the pc but my device, as i said, wasn't and isn't recognized anymore. What i can do? i can't even charge it, last night i connected it to the charger and let it on. When i woke up and unplugged it, it had no battery! probably it wasn't chargning, it was discharging, and the only way i can turn my mobile on, is plugging it to the usb, doesn't matter if into the power socket or usb-to-usb, even the screen lights up without the battery but still i can't go to the recovery or fastboot (probably, because as i said my device isn't recognized so either that's the problem either fastboot doesn't work). Here's also the video about this, maybe someone can help me since i don't know what to do.. thanks in advance.

I'm havin problems with offline charging after i installed cm11. I've tried change kernel and change rom (i'm using PA rom now) and i'm still with the same problem.
When i plug the charger on my phone while turned off, it shows a battery icon with a question mark on it and i think it's not charging. Is this a general problem or did i make something wrong?
Try keeping it plugged in. See if it charges or not.
Also,did you change your bootlogo?
I didn't change my bootlogo. it boots motorola bootloader and then shows the battery icon with the question mark. I left my phone charging this way for a couple of hours and tried to turn it on. my phone booted with 0% battery and then shutted down, so definitely it is not charging. other thing I notice is that when my phone enter this buggy offline charging mode, I have to press power button + volume down to reboot my phone, it kind of get stuck in this mode when my phone enter it
Try using a different charger.
It doesn't seem to be a common issue.
Can you power up the phone whilst charger connected.?
I've tried two different chargers, one of my Moto X and the original one. If I want to charge the phone I need to turn it on first and then plug the charger. I can't turn it on with the charger on cuz it is stuck on that screen with the battery icon
I'm starting to think I've done something wrong. I did the following to get where I am right now:
I was on stock firmware, so I rooted the phone and installed the newest version of SS. Then I downloaded cm11 and gapps and copied to the phone. I entered the SS and wiped everything. After that I installed cm11 and gapps.
When I discovered that issue I've tried install JBX kernel to fix it and nothing. then I wiped everything again and installed PA rom + gapps and still that issue. Did I do something wrong?
No, you didn't do anything wrong.
Since its persistent across both ROMS, its not a ROM issue either.
In my opinion, its most probably a problem with port or the board. The port doesn't deliver enough power.
You can try flashing the stock ROM back, it might repair in case something s/w related is corrupted. If it doesn't work after that, then its a h/w glitch for sure.
just in case, if I install stock rom and the problem goes away, what might be causing this problem?
I can't re-flash stock rom because I can't charge my phone and I can't boot into the rom or recovery. I don't think fastboot charges my phone. I just realized that bootloader is locked. Maybe this is the problem, isn't it?
it isn't a h/w glitch because before cm11 it was OK to charge offline
You'll need a factory cable to flash in case your phone has insufficient power.
Look for it, there's a guide about making one in the general section I suppose.
No need, I've managed to charge the phone through USB on my pc. When I plug the charger on my phone, that glitch happens, but when I plug the USB on my pc, the phone lights up a white led and apparently it charges the phone (slower, but charges). That's really weird. I really want to know what is happening to my phone
Hi. My xperia Neo crashed, I tried to send a photo via bluetooth and the phone just turned off. I tried to turn it on, it appears the "SONY" screen, then the "XPERIA" screen, and then it restarts, over and over again with the same 2 screens. I searched topics, they say that I have to flash it, but I can't start the phone in flash mode, with power and back buttons, any software (Companion, flashtool) don't detect the phone. Is there any solution?
Just like death

Hi, I´ve got similar problem. A year ago my Neo V went dead (I thought so). Just for fun, I tried to connect it to PC yesterday and what happened? It started charging and after few minutes I started it (YAAAY)! So I thought It was just some bug that disapiered after discharging. So I did a hard reset, to gain factory settings, repair the firmware via PCcompanion, everything was OK until I shove a memory card inside. After that it died again. Its not charging, no reaction after connecting to PC, no reaction on ON/OFF button, no reaction for button-hard-reset, no response while trying flashing with EMMA or FLASHTOOL, nothing... Does anybody knows what to do with it or do I have to wait again until it discharge and pray it would work after that?
help
I have the same problem as you did it to solve? :crying:
Hello,
I picked up a white Sony Xperia Z Ultra two days ago. Yesterday it died because of my own stupid fault.
So, I got it second hand. Everything working fine, but, it had CyanogenMod 12. Only I noticed it was quite buggy with phone calls, WhatsApp, etc. So I wanted to flash a stock ROM on it.
Using Flashtool I tried flashing it, no success. So then I decided to put CyanogenMod 10 on it, given I heard it was stable. I thought if calls and whatnot are all stable I don't really care.
I booted into recovery and flashed it, and now it won't start. It's stuck on the Sony logo, the LED is purple but turns to orange.
Also I can't get into recovery. I tried recovering using Flashtool, but I get a loader.sin error.
It does respond with 3 vibrations when I press power + volume up.
On power + volume down my phone gets connected to my PC, but disconnects itself and boots up, or atleast tries to, but, stuck on logo.
Sony Companion doesn't recognize it either.
Right now I am at the end of my rope, given I just got it two days ago, and I enjoyed the phone for like 4 hours...
Please, can somebody help me? I searched the forums for hours.

First of all, let me clear that;
1. The 3 vibrations are related to hard reboot, so forget about it.
2. loader.sin error usually appears when ALL the drivers isn't installed properly.
3. Finally,
your phone connects for a while after pressing volDN+connect USB.
This means Drivers isn't installed on your PC.
Solution:
First of all, install essential drivers to your PC.
Navigate to Your Flashtool folder (where you have installed) and then open DRIVERS folder. Install it for your phone and CHECK boxes (Xperia Z ultra, Fastboot, Flash mode).
Now,
In Flashtool select your downloaded .FTF and flash it.
Hope the above guide helps you and your phone gets a life.

I found out what the problem was.
All the drivers were installed correctly and so on and so on, but, apparently, the USB cable was just messed up... I have another phone here, a Samsung Galaxy Mega 6.3, and that one can't connect either, only charge for some reason.
Used a laptop with another USB cable and all worked, so now I am finally enjoyed my fixed Z Ultra with Lollipop. Great phone so far~
Hi guys. So I have been going through xda and Google for hours and hours trying solutions, to no avail. I almost never post on forums for help because I can usually find the solution. Not this time. This is my last resort next to throwing my phone out a window or praying for death's sweet release.
The facts: I have a rooted Xperia Z3v. I tried to upgrade TWRP in order to follow some directions on upgrading to Nougat. I flashed TWRP from 2.8.X.X to 3.X.X.X. I rebooted and it never made it to the Sony logo. Now, if I plug the phone in to either a wall socket or PC it vibrates, endlessly at three second intervals, each time with red LED. If I try to enter flash mode, then its the same but with a brief green led after the red. I can enter fastboot (the only way to stop it vibrating while plugged in) and my PC sees it, including Flashtool, but since my bootloader is locked permanently, I can't really do much with it.
When plugged into the wall-charger, I noticed that the charger's LED changes from "Active" to "Inactive" with every vibration. I'm pretty sure I'm in a reboot loop. The screen is totally dead and there's no logo, but every three seconds it kills it self and comes back.
I have tried everything I could think of.
What I have:
I have the stock firmware ready to go
I have TWRP backups on SD card and PC
I have Flashtool
I think my drivers are good, but not 100% sure
I can fastboot
I'm at my wit's end and losing hope.
Please, I'm open to any suggestions at all.
