sending 'boot' (20480 KB)...
OKAY [ 2.462s]
FAILED (remote: image is not a boot image)
finished. total time: 2.466s
Now before we all start screaming bad download, here's the list of things that I've tried...
- I've tried multiple boot images from various sources, validating md5 sums accordingly. I even tried the restoration procedure from your thread about restoring to stock.
- I've tried to erase the partition using fastboot (which doesn't return an error) but I still can't flash after that.
- I've tried using a different OS with fresh drivers. I normally run on a Fedora 20 box but I've tried on Windows 7 using Flashtool as well.
- I've tried to wipe & clear cache. (Didn't think this would help, but what the hell?)
Anyway, I'm out of ideas. Any thoughts would be greatly appreciated.
And thank you for all of your hard work on the Xperia line. I've appreciated all of the posts in this forum, the system images and tutorials, as well as the custom recoveries!
: flashing boot.img from CM11 works fine. Clearly I'm missing something about how to flash the boot partition on this device. Apparently not all boot.img files are created equal...
: I can flash the Advanced Stock Kernel with Dual Recovery without issue, so I'm going to flash my way back to 4.4.3 and go from there.
: In the end, it was because I was using an ELF image and fastboot didn't like flashing it for some reason. I reverted my phone back to 4.4.3 using the stock system.img and FOTAKernel.img, then used the Advanced Stock Kernel with Dual Recovery, since they were all flashable via fastboot. Once the system was up, I used adb to push the 4.4.3 stock boot.img to the device and the did an adb shell, su'ed to root, and dd'it onto the boot device. Rebooted, OTA'ed it to 4.4.4. Done.
What a night. This is what I get for starting this project late...
