My first ever contribution, always been a leech until now.

Instructions
Details
Device: Xperia Z2 Tablet - LTE
Model: SGP521
Version: 17.1.A.2.69 - stock
Customisation: 1281-5556 (Global LTE)

Changes - coming from 17.1.A.2.55
  • Probably not many, the last fw was 17.1.A.2.55 (only 14 iterations behind this), but judging by the speed they threw this out it probably fixes critical bugs/security
  • Vastly improved touch responsiveness (.36 = unusable, .55 = barely acceptable, .69 = pretty good!)
  • Much faster at everything (not tried benchmarking)
  • Let me know if there are other changes and I'll list them here

Stability seems to have degraded.

I never noticed any random reboots before in about 3 weeks of use, but I've just had one with this fw.

This FW is NOT rooted.

If you unlock your bootloader and use DooMLoRd's kernel then you can obtain root.

That at the minute is the ONLY way to root this device regardless of FW..

BUT - I already posted a question in this respect in Doomlord's CWM recovery thread - it is very much possible that Doomlord's kernel & recovery is NOT compatible with the .69 firmware! So... *eerie music* *ghostly voice* B R I C K D A N G E R!

As you can read in that thread, prerequisite is a .55 firmware.

But perhaps someone clears this up.

Judging by the very small increment number between the two firmwares and without going and looking it up I would place a high probability that the base stock kernel hasn't been changed and would, therefore, custom kernel compatibility is implied.

If you have the .55 fw or can obtain a 'About tablet' page view from that fw, you can compare the kernel versions to the screen in the OP and take a gamble.

But, in my opinion, the risk of bricking low, assuming you don't do something out of the ordinary.

Checked it with this FW .69 and the modified Kernel from DooMLoRD for the .55 Kernel. Worked like a charm...

This FW did fix touch screen issue a little bit, still the screen edge got very poor touch sensitive.
