Hi everyone, so i recently acquired a Sony Xperia Z Ultra C6833 from my cousin before he left for europe.
Naturally, i wanted to restore it to its factory settings so I could start clean with the phone.
The problem is. I can't seem to do it
My cousin has a lock screen pattern on the unit and I don't know what it is, I asked him and he said he already forgot what it is, nor did he set up any recovery questions or an e-mail to unlock the phone. (I already tried this avenue and I am all but certain that this isn't the way to go, please bear with me and don't offer suggestions based on trying to unlock based on the pattern)
I searched online on how to reset the phone to factory setting without having access to the menu. (I had thought that all Android phones had this feature by pressing combinations of physical buttons). However none have worked.
1. I've tried pressing and long pressing the "red" hard reset button near where you insert the SIM and microSD card, I long-pressed it while the phone was open and all it does is shut down, and it does nothing when the phone is turned off.
2. I've shut the phone off, and tried opening it using different combinations of volume keys and power button.
a. I tried holding down both volume and power buttons for long periods of time. Nothing happens.
b. I tried holding down the volume up button as well as the power button. Again, nothing happens.
c. I tried holding down the volume down button as well as the power button. The phone starts in Safe Mode, whereupon I cant do anything there anyway since I can't unlock the lock screen pattern in the first place.
3. I downloaded PC companion in my PC and was going to try to use System Update / Repair on it. But THE PC WONT DETECT THE PHONE. I assumed it was because I didn't have the drivers for the phone, so I downloaded the drivers online within a zip file but all it has is a bunch of .inf and .cat files which I dont know how to execute. So I cant connect the phone the PC at all because i dont know how to install the drivers that will enable the PHONE to be detected by PC Companion.
I really need help and really want this phone to work and for me to use it. However, I just cant seem to restore it to its factory settings given that I cant unlock the freaking phone pattern. :crying::crying::crying:
Thanks in advance guys and any help will be highly appreciated!
- Download Flashtool (on your computer)
- Download a TFT (firmware) here at XDA
- Kick the phone into flashmode by holding VOL DOWN while you connect it to your computer
- Flash the TFT in Flashtool and 5 minutes later you're good to go.
This won't void your warranty btw.
I'm on mobile right now, so I can't bother sharing links, but I can do it when I'm on a computer (but you should easily handle that task yourself )
Any questions?

Hi! First of all, thanks for the response.
A couple of questions though...
I've downloaded the flashtool (this is Emma right?)
Could you give me a link to a valid TFT? I'm not sure which to download, I'm from the Philippines and I need the TFT that connects to the playstore and all that (perhaps just the stock ROM?)
Also i've read that I need to unlock the bootloader for this method to work? Problem is, I can't seem to find out how to do this or even if my phone is viable. I've tried inputting *#*#7378423#*#* in the emergency call menu but nothing happens
*EDIT* Okay I connected the phone to emma and found out that the bootloader is still locked. Need help on how to do this.
Again, big thanks in advance!

DON'T RUSH, slow down
You dont need to unlock the bootloader to flash FTFs, and they can be found here http://forum.xda-developers.com/showthread.php?t=2453921
I've not used emma, we all use flashtool http://www.flashtool.net/download.php
No, you don't have to unlock the bootloader. You only need to do that if you're going to flash a custom (CM11, PAC, GPe) ROM.
- Download Flashtool and follow the installation guide (be sure to install the drivers)
- Download an FTF from here (this one will work just fine)
- Put the FTF where you installed Flashtool (C:/Flashtool/firmwares)
- Connect your Ultra to your computer
- Open Flashtool. It should say "Device connected" etc.
- Click the "Lightning bolt" icon
- Choose the firmware from the list to the left
- Hit "Flash"
- Follow the steps on screen
Tip:
- Flashmode = Turn your Ultra OFF. Hold VOLUME DOWN when you connect it to the computer. You will se a short burst from the LED, but it won't stay on.
- Fastboot = Turn your Ultra OFF. Hold VOLUME UP when you connect it to the computer. You will see a blue LED.
thanks!

Hey, I know this is not correct place for Xperia X10 issue's, but i need to display it in general section, as this one is getting critical..
I uploaded a custom rom on my xperia x10, for that i unlockd the bootloader and stuff..
Now, my phone is switched off since 15 days, when ever i try to switch it on, it vibrates once and nothing at all afterwards...if i press power button again, it won't vibrate, unless and untill i remove the battery and reinsert it in phone..
i see three red flashes of light, when connected to PC..
1. PC Companion for update, repair and custom repair is not working...most of the time phone is not detected..
2. SE-update service is also not working and phone is shown as Xperia arc..
3. Flashtool, doesn't recognize the handset
4. few, technician told me box flash would work, but again, it didn't work out
Now, i don't know much about this, but i do understand that hardware seems to be good, till now, the only issue is software and that to initial boot process i.e. bootloader.
is there any other way i can upload a new custom rom on my xperia ??
or any other solution, will be appreciated..
I'm assuming download mode didn't work? Pull battery and insert cord/battery/press back button at same time while aytempting to flash through flashtools?
I have tried flash tools with this method, but doesn't helps..
I don't know about download mode, is it the same done through PC companion..
Thanks

I had the xact same problem and this worked for me..THANKS A LOT..i owe you one
Same issue
I have a similar issue.
When I try to flash it through flashtool, I get this error
"ERROR - ERR_SEVERITY="MAJOR";ERR_CLASS="SECURITY_CLASS";ERR_DYNAMIC="SIN header verification failed""
Plus the phone is not also going in the recovery mode.
Please please help me.
Red light shines for a few seconds, when plugged into charger, or computer. Flash Tool shows "Device connected with USB off", and "For 2011 devices line, be sure you are not in MTP mode".
Pushing, holding any and all combinations of power, volume up/down produce no other lights or actions in Flash Tool. This includes pushing in the "red Reset" button, while using the above combinations.
Bootloader is unlocked. Was trying to downgrade and I think I [email protected] up & flashed a wrong tft file.

The only thing I can suggest is:
Start flashtool
Connect GPe Ultra
Hold the vol - key down (use a rubberband or the like)
Hard reset using red button
Watch for LEDs and flashtool output
Thank you Blueether. Tried just as you suggested, but no reaction. I wish there was a way to turn usb debugging on. With out that, seems hopeless.

Yes it did.
Why are you worry so much, if your device is going into flashmode and showing in flashtool you are golden.........................no need for the usb.....debugging
just fire up flashtool connect your device to flashtool and falsh any ftf file (you have to download it preferly specific for your model from here http://forum.xda-developers.com/showthread.php?t=2453921) for your device don't exlude anything aaaaaaaand you are done.................
yepp... as the post above states, nothing much to fear at this point.. forget usb debugging... thats not relevant at this point.. just load n FTF and start flashing (without connecting the phone) till it gets to the point where flashtool will ask u to connect the phone in flashmode pictographically... connect the phone on usb (hooked to ur pc) holding the vol key down (with the phone powered off - obviously power's off thats why u scared its bricked).. u'll see a green led flash on ur phone for a sec... and on ur computer, u'll noticed that the flashing has begun.... just to be safe... to avoid ur phoney battery dying out amidst ftf flashing, see if u can leave ur phone hooked to ur charger for about 20 minutes atleast... before u atempt any of this... the phone might not turn on now... but it still can have its battery charged... alternately, if u happen to have a magnetic charger, u can hook that up to the phone the same time ur phone's connected to flashtool as welll... beats having to deal with worse situations if ur flashing gets cancelled midway... dont worry... we've all been thru it..
while ur phone's being flashed, u can download a RIC disabled modded kernel with recovery for the version of FTF u happened to flash.. download jackie's modded 681 kenel if u flashed 681 FTF... or chillychan's kernel if u flashed 290 or 136 FTF..
when flashin's done... and flashtool says unplug ur phone, do so and then much like u connected earlier, this time, hold the vol up (with the phone powered off - as it always does when flashing's over) connect phone back to USB.. this time u'll see blue led lit up continuously... thats fastboot mode... u can flash the above mentioned kernel using flashtool (i personally never used flashtool for fastboot mode) or like i do, flash the kernel using terminal (mac) or command prompt (windows) if u already have fasboot.exe adb etc from android development kit or standalone files..
then u can disconnect, start ur phone, set it up, download supersu onto ur internal or ext sd card, then boot to recovery. flash supersu and ur phone's rooted too... obviously, flashing kernel and su can be done anytime later not necessarily right after flashing FTF... i mentioned coz thats what i do... u can do it at any point it time since ur bootloader's unlocked anyway
hope all turns out well for u
This is for a GPe Ultra. No FTFs, only doomlords kernel,etc.
Make sure you know what you are telling someone in case you brick their phone.
Also note that they said it wouldn't go into flash mode.
OP can youu try the my steps again but with the vol up key held in?

Yes, tried it all again with vol up key held in, no result. In FlashTool, flash mode, I can see the FTF under firmwares that bricked me. It's a .290 ftf for C6806 models. Debating weather to try the Hard Brick method or just paying Sony to repair it.

Sadly no. Played dumb with Google store rep. & sent it back. They received it 8 days ago. Supposed to have an answer by 14 days. Instead of option of receiving a new phone, that I would have to pay for, I chose a refund. If they tear it down I'm screwed. Bootloader was unlocked. Good luck to you.
Last night, i accidentally swiped to restore to an older ROM that i had. Not meaning to do this, and beginning to panic, i attempted to stop it, while it was still at 0%. I did this by holding the red button down. As i have now realised how stupid that was, i am wondering if there is any chance to fix it. It is now stuck on the Sony logo. Although i have seen many problems here, i cant find anyone that had the same problem as me. I was running the existenz ROM, and the ROM i was accidentally restoring to was the official ROM. Please help me
Thank you

I had the exact same problem, I created a guide to help other people with this problem. Here it is. I can't post links yet but if you want to have a look, search for this on google ( oneplus : Xperia z2 bricked help!! ) It's the first link ( fourms Oneplus Net )
---------------------------------------------------------------------------------------------------------------------------------------
To get Sony's UI/ROM back:
Download and Install Flashtool from here.
Download a proper ( official ) ftf firmware for YOUR phone ( eg Sirius ).
Now copy the downloaded ftf firmware file to ( C:\Flashtool\firmwares )
Open the Flashtool and click on the little lightning rod and choose Flashmode.
Now a window will pop up and ask you to choose firmware for your device, Choose the one you downloaded and click flash.
--------Choosing a wrong one WILL further brick your device--------
Meanwhile, turn your phone completely off, To do this hold the Power button and the volume UP button until you feel your phone vibrate 3 times.
Flashtool will pop up saying you need to put your phone into flash/fastboot mode.
Now put it on fastboot/flash mode ( connect the usb to your computer and hold down the volume up button while plugging the other end to your phone. Your phone's LED should be blue at this stage.
The flashing process will start and once it's done, Flashtool will ask you to unplug the device and restart the phone.
The first boot takes 5-10 minutes.. CONGRATS YOU HAVE UN-BRICKED YOUR PHONE.
Now if you want to root your phone and install a custom recovery ( TWRP ), Download this package and extract it on your desktop
Make sure you have usb debugging turned on ( on your phone )
Navigate inside " to root" folder and run install.bat
Once thats done, to install recovery, navigate inside the " recovery folder " and run install.bat
Make sure to follow on-screen instructions. ( your computer and your phone )
Now you have Rooted sony ROM.

Currently, I'm making a toolkit for all xperia z devices, just hoping it goes according to plan
my xperia device is stuck on the sony logo. wont pass that part. doesn't go into flashmode or fastboot, nothing. what can I do plz I need help. cant use flashmode on the pc as the computer never recognizes the phone bcuz it doesn't go into fastboot mode.
If your phone even starts, then fastboot and flashmode should work just fine. What's the last thing you did before it wouldn't boot?
1. Hold VOL UP while plugging it in the USB on your computer. The LED should get blue
2. Either use fastboot through command-line or use QuickIMG to boot a custom kernel with recovery.
3. Flash or restore a ROM

Do the following exactly as outlined.
1- with the phone DISCONNECTED from your pc or charger, hold the power and up buttons until it vibrates and turns off.
2- open the flashtool and select an ftf to flash, and wait for the message that asks you to connect the phone in flash mode.
3- the phone must still be off. Hold the down button and connect the phone to the usb port in the pc. The flashing will start.
I tried that it goes back to the sony logo.

How did you try to unroot? It's weird if you don't have working fastboot or flashmode, and without those, you're pretty much screwed. Those two should work even if you screw up big-time, like flashing a wrong kernel, but you must have done something weird if they stopped working?
And let me get this straight, you are pressing and HOLDING the volume buttons when you plug it to your computer, right? Make sure that the device is completely off by pressing and holding POWER + VOL UP. It'll vibrate a couple of times. Note that you're not supposed to be connected to the computer, since it'll then just boot again.
Then press and HOLD VOL UP for fastboot (blue LED), OR VOL DOWN for flashmode (green LED flashing shortly)
You probably already know these steps, but we have to make it absolutely certain that it's a hardware issue, and not an issue with the thing you do

I was going to flash the stock rom using flashtool right but everytime i tried to put the phone into fastboot mode it would go to the battery icon. At this point the phone was working fine. But no fastboot mode at all. Then i factory erased the phone through twrp. After that it doesnt boot up. Just sony logo no led lights. Even if i do vol up or down. Straight to the sony logo. Vol up plus power button, vibrates couple of times. I redo the process and it goes back to the sony logo.

The thing is that the screen shouldn't power on when you enter fastboot. The only thing that should go on is the blue LED. I don't use TWRP, and I don't know how it wipes stuff and if it only deletes user data, or if it formats the system. If it does the latter, then it literally wipes the system partition, making it empty, so if you ever format the system, you should flash a new ROM ASAP. A little late for that now though, but I'm still not convinced that fastboot isn't working.
ONE LAST TIME :laugh:
NOTE: The device should be disconnected from the computer.
1. Turn the device OFF by holding and pressing the POWER button and VOL UP. It should be disconnected from the computer by now. Got it? Nice.
2. Plug the USB-cable in the device first, since it's easier to plug it into the computer. Do not plug it into the computer yet. Only the Ultra.
3. Now HOLD VOL UP. Just hold it in.
4. Stick the USB cable, which is already inside your Ultra, to your computer WHILE still holding VOL UP.
5. The blue LED above the screen should light up now. The display should not power on or anything else. The blue LED is the only thing that should turn on.
Still nothing?

Check whether the drivers have been properly installed in ur PC. If u can't get into flashmode try another system to flash the ftf. Procedure hold volume down while connecting the usb to plug. U will see a green led blink.

Oh! You probably haven't installed fastboot on your computer. Download and install, and try again.

Wooooohoooo phones alive jajaja. Thankssss. Though i got some more questions. First time i unlocked boatloader i was told to backup my TA files. what do i do with those now? I just flashed a stock c6806 unbranded rom. When i try to update the phone through settings it says it couldn't verify the update. i retried the process through sony companion app, and it says my phone is modded so it wont do anything.

The TA partition is where your DRM keys are. It's a good idea to backup those keys in case you want to revert to complete stock in the future, or when you need to send it in for repairs. Unlocking the bootloader will remove the keys, but since your device was - weirdly enough, already bootloader unlocked, I don't think you even had DRM keys to start with, which is again, very weird.
No biggie though. Gone is gone. The reason why PC Companion told you that it's been modified, is because you're rooted, and it knows it, so you'll have to unroot before you update. That's only if you're updating through official channels, but you have a second alternative; Flashtool. It allows you to flash stock Sony ROMs, or FTF-files.
But you're saying that you flashed a stock 6806 ROM now, and that's what? 5.0.2? Why don't you just download the .368-update (Android 5.1.1)? Then you'll be on the latest version.

I did unlock bootloader myself, TA file were backup. My phone is the 6806 model. The only ftf file i found on xda with a working link was for 4.2 jellybean. I just restored my TA files am going to reflash that stock rom and see what it says now.

have my xperia z ultra same error that file will solve i dont know if my sony has unlock bootloader,
Hello,
I have recently made a horrible mistake, I flashed the incorrect ROM on my Xperia Z3v leaving the phone bricked. I am asking for your help. I have tried using the Flashtool but I am not certain if it's the phone or I that is causing a mistake. The steps thus far that I have followed.
Downloaded: Flashtool & Drivers
Installed: Drivers for Xperia Z3v
Downloaded: Firmware from XperiFirm
Now, the issue next is nothing shows up in my firmware when I attempt to flash. I have checked the source folder the .ftf files are there.
Furthermore:
When I hold VOL UP and plug in the USB>Blue led is indicated
When I hold VOL DOWN and plug in USB>Red flashes with a second of green whilst vibrating
Found this video on youtube: https://www.youtube.com/watch?v=dtaUxuorVSA
Exactly like this, checked for a solution seems like he repaired it via sony. Unfortunately for me I don't have that luxury.
**Update**
I installed the lastest release of flashtool (0.9.22.2) but it occurred to me to revert back to the previous release (0.9.18.6)
Now I can finally see the firmware but I am still having issues actually flashing the file. I get errors such as:
ERROR - root : this bundle is not valid
ERROR - Cannot delete C:\Users\Juan\.flashTool\firmwares\prepared\userdata.sin
**More Information**
I should include I am on a locked bootloader
same
that seem the same with my situation
Okay the green light is flash mode / upgrade mode. The blue light is fast boot. You want it on with the green light on to flash it once it's bricked. You can't flash it using fast boot mode because the boot loader isn't unlocked.
Now what you have to do is get it with the green light on and then the drivers installed.
Can't delete the file means that it had error while trying to flash and all that you have to do is restart the app and that goes away.
Now for the next problem is that I had this one and what I did to fix it is that I had to reinstall the drivers because those weren't correct and I did reinstalled it and it all worked good. Thanks.
Download the correct firmware for your phone (model and Country).
Use flashtool to install it on your phone
Works with a locked bootloader, no need for USB debugging.
The first error might be you ended up downloading the incorrect or incomplete firmware
I had the exact problem that you are having. I ended re downloading the flashtool a few times from various computers and then i got it to work. I figured when i downloaded it the first time i had a version that was to old/new. Or a bad connectiin when i downloaded it first time. After i downloaded flashtool again itthwn worked without issue just as it should. Whatever the provlem was for me was having to do with the download or version i downloaded wouldnt work completely. I think my internet connection when i downloaded it wasnt very good and maybe didnt download it right.
I made the same mistake too, trying to flash a z3 zip file. Then I got to run around my home city to find help. Then there's a guy. He had to open the back cover and connect directly to the circuit board in order to do something about the eMMC and SEtool or... something, I'm not sure. The phone is alive again! (costed quite a lot for a student, but... yay?). Funny though, he said the circuit board is similar to a z2 and not a z3. Maybe you could find someone who knows about these kinds of thing. Hope that help.

That's strange were you on a locked bootloader?
Currently attempting to fix it once more, will update if I find anything out.

Yeah, I think? I mean, it's right out of the box. Also, I think it's worth mentioning that the guy had to use SEtool twice to get mobile signal.
Did you fix the problem? I have the same problem now.
With a Z3v. D6708. I have a problem, got a wrong ROM, the flashee and now not start the phone in any way. The only way to start is "System Recovery" volume + power, which has 4 options: 1. "Continue Power UP", 2. "Safe mode", 3. "Factory Reset" and 4. "Power Down". The thing is try from flashtool but when I give "volume down" and connect the computer does not recognize. When light it even reaches the boot animation. When I give power with USB cable is connected in a loop is vibrating and shows red, blue and green.
I have exactly the same problem of the youtube video.
As it could fix the problem?
Some help ?
Thank you !
Pd. The device only have FastBoot.
did u solve this?

got solved? me to have same problem
Bricked for days!
Is anyone still following this thread. I have the same problem after trying to install MIUI 6 on my rooted unlocked TWRP'd Xperia z3V. After the MIUI installation I have nothing but the symptoms below.
Not able to get into flashmode
No screen or bootup
No recovery
Symptoms:
1 -When plugged into PC or wall it only blinks RED/GREEN light and vibrates.
2 -Holding POWER the light turns and stays GREEN until released (then returns to #1)
3 -Holding POWER + VOLUME UP BLUE light stays on and puts phone in Fastboot mode
4 -Holding POWER + VOLUME DOWN does nothing (continues to do #1)
Please Help!!!
Google Sony Developers. Try to unlock your bootloader.
Sent from my D6708 using XDA-Developers mobile app
I think the phone will reject the command. Tried on a bricked z3v and that's the response I get from fastboot with the Sony commands given through the developer aite.

The phone is not and most likely never will be bootloader unlocked. Planning to buy for another phone is your only option.
I've already moved to a tmo note 4. Not much development there either, but it's nice. Miss the z seires though and may come back to it next year. We'll see how they fair with phones for the next few months state side abs if prices even out on the x or z5.
I fixed mine
I bricked my phone it was just a paper weight Email Me I will make u a video step by step instructions to fix it

Unless you're going to post a link or YouTube video we all have access to, wouldn't bother asking people for direct email addresses to send them. That's the reason for PM'S and the forum on general. If you have a fix, we'd all like to know what it is you were able to do that none of us have figured out.
