I'm working on a small project and am currently looking for a Tablet that I can use. As far as I understood, the "Sony Xperia Tablet Z2" (SGP 521) could be a good candidate for my project. I am asking this forum to potentially assist me with your knowledge and experience if the following is possible with the device:
(Some questions or comments seem to be obvious but I still write them down so that I can be sure we are talking on the same level. Please do not simply refer me to the search functionality of the forum, I did my homework and searched each of the topics before -- I just need a first-person-confirmation of someone if the below is really working.)
- I need to modify and compile the Linux (Android) Kernel of the device. Thus, the Source-Code of the Kernel for this device needs to freely available.
- The modified Kernel needs to be able to be uploaded and booting from the device, thus the Bootloader needs to be unlocked.
- The device needs to have running NFC and LTE communication, plus touch and usual tablet capabilities. For this, the necessary binary-drivers need to be able to be integrated to the custom kernel. I expect the drivers are not common (GPL-like) drivers but proprietary and at maximum available as binary-package to be integrated afterwards.
Is this all possible or can I expect major problems somewhere? The used LTE network most likely will be some LTE network in Germany. To my best knowledge, it is possible to unlook the bootloader and compile a custom kernel. Critical point is: Is NFC+LTE working and available as binary package to be integrated in the custom-kernel?
Thank you in advance for your time!
