C6833 upgrade/downgrade using fastboot - Sony Xperia Z Ultra

Hi guys.
I just need some inputs here because I'm on a deadend.
I am currently working on a friends Z ultra that has bugs on current build 14.6.A.0.368.
The thing is, when I am trying to enter flashmode, its not letting me because it will just blink with the green led then it will turn off. However, I have no problems connecting on fastboot mode.
So I am just wondering if there is a way I could somehow install a recovery on the current build without using flashmode? Once I have recovery, I could figure out my way from there.
Hoping someone can help me. Thanks in advance!

1- The proper way to enter flash mode is to first turn the phone off which I think you can do with no problem. Then while the phone is off, hold the volume down button and connect it to your pc with the USB cable. It will not show you a while lot of visible signs of entering that mode but if you are running software on your pc, like flashtool, that anticipates this mode, it will show you that the phone is in fact in the flash mode.
2- If your phone is rooted, you can install Xzdualrecovery. You download the latest installer (not flashable) version for xperia Z ultra (Google it to find out where to get it) and then run the installer on the PC. Then you put the phone in USB debugging mode (Google to find out how) and continue with the installation. If the phone is properly rooted the installer will put recovery software on your phone and ultimately reboots it into recovery.

install those three and i'm sure your problem will be ok
Hi @bluestricker_21

Flash and fast boot drivers are installed using the exe downloaded from the link you have provided.
Restarted machine
Still not detecting the phone in fast boot mode.

If it is not detecting then the problem might be your cable

You can get into fastboot without flashtool if drivers are correctly installed.
Stupid question: Have you already unlocked your bootloader? If you haven't done any modding before (e.g. flashing custom ROM) you might haven't done it so. That can explain why your phone goes charging when you plug USB cable instead of fastboot mode. Try also some Linux live distributions. Some of them have adb and fastboot included.
I have done flashing and modding.
But right now I am not able to put the phone in fastboot mode
I am expecting some helpful comments instead of asking me to search for answers.
Because I have already searched for those, came here finally.
Please provide helpful comments to put the phone in fastboot.
I am not able to find the answer
How did you unlock your bootloader?? I mean by which method did you do it?

First, you didn't provide importrant information. Which ROM you currently have, which one you are trying to flash, have you tried to update firmware via OTA, because there are some situations where you can accidentaly relock your bootloader. I assume you didn't brick your phone earlier with FOTA, like in my case.
Next, when you try to connect into fastboot mode, try it without FlashTool and open device manager and watch if it responds when you try to connect phone with usb while holding menu key. Fastboot is a command line application which can work without FlashTool (which is a GUI frontend to fastboot).
Second, you didn't read my post thoroughly. I suggested you to try a Linux live distribution, e.g. ubuntu. Just boot it from CD or USB and when it is ready you can connect phone in fastboot mode, just hold a menu key and plug the usb cable and see if blue light goes on. It will probably not solve your problem on Windows, but will give us some answers.
I too am facing the same problem!
Im currently using CyanogenMod 10 with the same Kernel which was pre-installed on the Neo V when I bought it.
I wish to change the Kernel to Lupus as it is compatible with most of the ROMs. I tried flashing the kernel with Flashtools and Kernel Flasher but to no avail.
Kindly help!

I have the same problem. I want to get into fastboot mode but nothing happens. The computer only gives a sound of connection the device and that's it. No blue led when pressing home and connecting to the computer.
How can I flash the kernel?
I have adb drivers installed
When I normally have neo running then there's no problem in turning int Fastboot pressing a lighting in flashtool

[Q] Tablet Z bricked?

Hi there,
yesterday I tried to root my new Tablet Z (16GB, LTE, Model: SGP321, Firmware: 10.4.B.0.569) and it doesn't start since then.
I used an ubuntu live CD for all these tasks because fastboot doesn't work on my win 8.1 and my debian wheezy didn't have the libc-dev needed in its repositories (didn't want to mess with packets that weren't yet integrated into my OS).
What I did:
unlock the bootloader according to http://unlockbootloader.sonymobile.com/instructions
I followed the instructions here: http://forum.xda-developers.com/xperia-z/general/how-to-root-10-4-b-0-569-t2590781
a few annotations to this:
the firmware rar didn't include a "Recover.zip", so I used the boot.img directly inside the firmware rar
although sony and this CM tutorial use the "-i" parameter of fastboot, I didn't use it because it wasn't used by the tutorial
after I did the "fastboot reboot" step, the device wasn't listed anymore when typing "fastboot devices", which, I think, is okay since the device should restart then.
I think it didn't really restart, because the LED on the side glew red.
I tried to turn on the tablet but it didn't do anything (the LED kept glowing red).
I tried holding vol up and power for a few seconds (until the LED blinked first once and then three times) but the tablet wouldn't do anything except for the LED glowing red. at somepoint, the LED would turn off (I think that happened when I hold vol up and power for more than 10 sec).
I was able to let it glow red again by pressing vol up and power again and release the vol up button before the power button.
I also tried to use the PC companion on my windows machine to repair the tablet but the tablet wasn't even recognized (either using the fastboot-procedure by holding vol up while connecting the tablet nor normal plugging in...)
any ideas what I could do next?
Same Problem!
Hey wullxz!
I have the same problem. Red LED most of the time, and I cannot make ANY USB connection to the PC. The tablet won't show up in the device manager. So obviously cant use flashtool, nor PC companion. Ive tried all this volume up and down button stuff, but simply cannot get it to show up on the computer.. Tried a different USB cable as well.. Same issue. The USB port is definitely not broken. Its brand new..
Have you found any solution ? Or anyone else? Mine just got back from Sony Repair.. they wont fix it cuz they detected that Ive tampered with the original software.... meaning Warranty Lost!
Great!
hi,
i also sent mine to sony for a repair. i wrote that i did a firmware update and the tablet wouldn't boot afterwards.
i didn't try the bootloader-unlock again afterwards.
Help Needed!
Tablet Z with unlocked bootloader and rooted 10.1.C.0.370
My issues occured after a downgrade to 4.1.2.
I CAN:
1) Start my tablet, everything normal...
2) Charge my tablet
3) Go into safe mode
4) Go into fastboot mode (solid BLUE LED)
5) Use the memory card and use root apps (maybe this could help restore?)
I CAN NOT:
1) Get my PC to recognize that a USB device is connected. Neither in Mass Storage mode, Media mode, nor fastboot mode.
- Tried with several cables and computers (this is not a driver issue, since it won't show up at all in device manager)
- Flashtool obvious;y says, no device connected
2) Get in to flashmode: device blinks red for about half a second, then green for half a second, and then LED is off. Nothing recognized via USB on PC
3) Get into recovery mode
4) Update over WIFI (fails because unlocled bootloader I suppose)
Any help would be greatly appreciated!
i think you should open a new thread for your problem because it seems like it's not really similar to my issue.
you should get more/better replies in an own thread.

let it charge to 100%, check for flashmode drivers installed and then try attaching it to pc only when flashtool asks you to do it.

Hey thanks for your reply... It wont go into flashmode... Theres something fundamentally wrong.. I cant figure out what... I leave it plugged in for 48 hours..but it doesnt really get full.. the most Ill get the orange LED.. like 50%... now its on since about 12 hours.. no LED on at all... strange..
But yea.. no flashmode... Nothing showing up when connecting the USB cable... nothing in device manager..and therefore flashtool sees nothing!
SOLVED
Problem solved! I can't believe it. Two bad(?) USB cables. Bought a new one, charges fine, flashmode fine. Flashed stock ROM.
However the Camera still doesn't work. Maybe the problem of the cable inside which may have come loose!

[Q] Bricked (Cant boot, turn on the screen)

Hey guys,
So I wanted to try out the newest CM12 ROM with A5.0 but seems like it didnt exactly happen how I wanted it. Rooting the device and then installing the XZDualRecovery without a problem. Then downloaded the ROM and gapps.
I have SGP311 (pollux_windy) so I downloaded that version of the CM12 at first. It said that my device is pollux, which I ofc was dumb enough to just skip and download the pollux ver and then install that one. So I installed the pollux ver instead of pollux_windy and when I hit restart device I didnt see it boot again.
So I wanted to connect it to my PC, PC didnt recognize it ofc. Only way my PC regonizes my tab is by fastboot mode. I had to install a driver for that. And even then only the Sony Mobile Flasher by Androxyde recognised it. I run into bootloop various times before with my tab and Emma always fixed it but thats unfortunately not the case here as Emma doesnt recognise it either :/
So now here's the problem, I can only do fastboot mode (not flashmode) and the only program able to do sth with my device is this Sony Mobile Flasher. I downloaded a official FW there and wanted to install it but it required me to go into the flashmode which I can't.
Is there sth I can do? The only thing working is the LED and fastboot mode.
Is there a way to put the device into flashmode via PC, that would solve all issues or maybe a trick to go into flashmode? As there was some thread about it but the thing they did didnt work for me :/
Please help
Thanks in advance
Nevermind, I just forgot how to use Emma....
For anyone to whom this happens:
Computer: Open Emma from the Start menu of your computer.
Connect a USB cable to your computer.
Phone: Turn off your tab.
Connect your tab to the USB cable while holding the VOLUME DOWN.
Computer: Select the software you want to flash in the Service list. The tool automatically detects the tab and lists available software versions, which are called Services in this flash tool.
Click on Apply Service. The tab will now be flashed.
Phone: When you have flashed your device, you can disconnect your phone from the computer. The first time you start your device after you have flashed it, the boot-up might take a little longer than normal.

Did you try twrp sideload adb push ?
yes, i tried adb sideload but say a thing like: protocol fault (no status)
Here is some thing that worked for me, even i could not get into Flash Mode.
turn off your phone
run flash tool, select the firmware you want to flash and click flash, wait for the tool ask you to connect the phone.
Now connect the USB cable to the phone with the Volume down pressed and do not let go of the volume down button until the flash process is done.
if the phone is still not detected, do the same but change the USB port.
it happens to me that if i let go of the Volume down button, the phone disconnect from flash mode.
if you are able to boot to home screen then it best to boot to fastboot using the option in Flash tool and then disconnect the USB cable, and then start the Flash process

Need help with bootloop -- A tricky bootloop.. Donation will be given!

Hi there peeps!
My Xperia Z2 has gone into a bootloop, with no recovery, no boot logo, not registering ADB / fastboot drivers anymore.. BUT.. the buttons seems to work, so i may reboot it some different ways. The only indication of life it got, is the red light when booting.
Someone want to tag team with me to find the solution?
Donation will be gived to a working solution
Best regards!
There is no solution for this atm. The best way to fix it is to send it to the service center.

I may have a solution. Red light usually means it cannot boot the kernel.
I have a simple fix. Follow this guide and make sure to download the firmware of your exact model and current software version number.
When you get to this step, on the right side don't check anything under 'WIPE', leave them blank. And under 'EXCLUDE', check everything except 'KERNEL'. Leave Kernel blank and the rest under exclude check them.
Proceed and press 'volume down' and connect the usb cable at the same time. Let the flash finish and boot the phone back up. Let me know how it goes.
Thanks! I'm trying your solution now, but i dont think it works... none of the drivers are either so. Give me some hours, i will walkthrough here
I can say, it is NEARLY dead i would think, but there must be a way somehow..
Yeah, this will not work.. It gets stuck on "HOLD THE VOLUME DOWN + PLUG THE CABLE" and both ADB and Fastboot are missing so.. It won't do anything there. Holding the Volume UP + Power reboots (that works for some reason). And the orange reboot button in the charging is working but nothing that will help me i think.

When the device is connected in flash mode (USB + Vol down), go to device manager and see if the device is there (may be called 'Xperia Z2" or "Unknown Device", right click and go to properties and update drivers to this. Update me how it goes. I had the EXACT same issue and it took me some time to resolve, by solving the drivers issue you can flash the kernel again without losing data.
If that doesn't work, install these drivers: http://forum.xda-developers.com/showthread.php?t=2588979

When my went to Bootloop the only thing that woked was using sony's Pc recovery tool.

Try Software repair on the new Xperria Companion
http://support.sonymobile.com/global-en/xperiaz2/tools/xperia-companion/
Both Sony Companion and Sony Emma are not registering the devices, but after fiddling around with VOLUME UP, VOLUME DOWN and lots of trying, at some point the device manager finds a unknown device. "hiredantispammer" may got the solution, but i will try all posted solutions right away! Post update soon
1. On "VOLUME DOWN + PLUG" the Device Manager refreshes, and the Z2 got the "red light" -- but Device Manager does not show any connected devices nor drivers needed.
2. The Sony Companion does not find the device either.
But.. i was reading about some Windows 10 driver problems, so i will try switch to Windows 7 x32 to ensure the drivers are working correctly.
Another thought.. Is it some way to put a "update.zip" on a sdcard for force installation of new kernel or anything?
Yeah, the solution is right. Hopefully Win 7 solves your driver issues. I had to reformat my laptop and install Win10 again because of driver issues when I have the exact same issue as you. Hope you get your phone working again!

And no, there's no other safe way to reflash the kernel. Even with an unlocked bootloader, you need fastboot drivers.
This worked for me.
Grab your original cable and make sure the phone is charged to st least 80%.
Start the pc companion and the repair program.
Hold the down key and connect to the computer.
In around 20 minutes the phone is repaired
Hope this helps.
It is important to use proper cable and not any old thing laying around. Mine would not connect until i got the original one.
Ah, charge your device fully. Reboot Windows 10 in safe mode and disable driver signature. Install device drivers. Use Sony PC companion or flashtool to fully reflash the right firmware for you device. You are still able to turn it off and on, so it should work if you do it right.
Best to first flash just the kernel and see if it boots, if it doesn't since you have the firmware files, flash everything and don't wipe data.
