[Sony Xperia Z Ultra] 7273457111:
Hello

I am attempting to flash my Xperia Z ultra sol24 variant for the first time. However I am running into problems and cannot seem to make any progress.

Ultimately, the goal is to root the device, unlock the sim carrier (au_kiddy) and flash the device to the c6833 Global rom, whilst keeping the 32gb internal storage that this latest variant (sol24 Japan only) comes with.

I am following the guide here (Its in three steps):

Firstly (http://tealic.blog.shinobi.jp/Entry/1663) I was told to backup and make a ftf backup using the sony PC companion and flashtool which I have done. The ftf file I had created is SOL24_14.3.C.0.239_au_KDDI.ftf

Then after doing so, the guide says to download the android SDK and adt bundle, then download the latest xperiaRootkit (rootkitXperia_20140719.zip) and extract the rootkit to platform tools folder of SDK and connect my XU to the pc using usb debugging the run the bat which will essentially root my device.

After doing so I downloaded the SuperSU app and finished the root.

I was then told to download the two files from (http://htcsoku.info/htcsokudev/rudimentary-knowledge/sol24-globaledition-rom/)

SOL24_Xperia_Z_Ultra_GlobalEdition_1.20.973.4.zip

SOL24_Xperia_Z_Ultra_GlobalEdition_Baseband.ftf

And place the GlobalEdition_1.20.973.4.zip onto my SD card, then using the XZU&Z1recoveryv4Windows tool (http://xdaforums.com/showthread.php?p=45149758#post45149758) boot into CWM mode and install the zip.

That is where my problems started, and upon installing the SOL24_Xperia_Z_Ultra_GlobalEdition_1.20.973.4.zip I selected the "reboot" option and upon reboot, it was stuck at the SONY logo and the phone would not boot any further.

I hard reset the XU and tried using the flashtool to flash SOL24_Xperia_Z_Ultra_GlobalEdition_Baseband.ftf as that is the next step in the guide, however the device was still stuck at the sony logo. So I attempted to flash my pre-made SOL24_14.3.C.0.239_au_KDDI.ftf file back to the device, which worked, but took me back to where I had started.

I am trying to redo the steps above but I am getting an error, I have re-installed the XZU&Z1 recovery v4 Windows tool to the device, command promt says that "Installing has finished" however my XU did not automatically restart and boot into CWM (Similar to the first time I installed it), and I cannot enter CWM mode on startup via manually shutting down and restarting. (The phone does not vibrate, nor does the green led appear) it just skips straight to the xperia logo and boots.

Is it possible that I have somehow flashed my pre-made SOL24_14.3.C.0.239 ftf incorrectly? As the CWM tool was working originally.

There are three columns, "Wipe" "Exclude" and "MiscTA exclude" on the side of the flashtool that I have played around with, however after flashing a few times and going through the steps I'm still unable to get the CWM tool to work, and am ultimately stuck at the moment.

I feel this can be easily resolved, however I am not sure which ftf to download or even how to properly flash the ftf(What do I need to exclude from the ftf flash?)

Can I please request some assistance?

Edit: I attempted installing the XZU&Z1 recovery v4 tool whilst the phone was off this time, and it was a success, it seems the CWM tool is now working properly. I will attempt to re-flash the global rom now.

Edit: After installing SOL24_Xperia_Z_Ultra_GlobalEdition_1.20.973.4.zip via CWM I am stuck at the SONY logo on boot again.
