[Xperia Z4 Tablet Android Development] retikulatus:
Hello everybody

i have a lot a questions ;)

i have a z4t LTE (karin-sgp771), on the service area , unlocking bootloader allowing is "NO".

1) If i understand correctly, bootloader and firmware are two separate things?

I mean, a specific .ftf file will never be able to set "unlocking bootloader allowing "yes"?

2) With this device, can i still flash stock rom (.ftf files) with flashtool?

3) can i flash the Nimadroid (thanks to him!) [ROOTED][STOCK][KERNEL] [SGP771 - SGP712] 32.4.A.0.160 DRMFIX, BusyBox on this topic

4) i installed the z4t drivers (sa0112adb.inf) + UniversalAdbDriverSetup.msi + Update_Service_Setup-2.11.12.5.exe AND xperia companion (update service doesn't load , there is message it can't work, whatever)

in normal mode, my device is perfectly recognized by flashtools (INFO - Android version : 7.1.1 / kernel version : 3.10.84-perf-g99119bc / Build number : 32.4.A.1.54) and xperia companion. But when i put my device in fastboot mode( vol up) or recovery mode (vol down), my device is no more recognized, i have the flashtool message:

ERROR - Drivers need to be installed for connected device.

ERROR - You can find them in the drivers folder of Flashtool.

So, i installed the flashtool xperia drivers pack v1.9 ( in the flashtool drivers folder), i choose flashmode drivers, fastboot drivers AND the Xperia z4 tablet device drivers.

Unfortunatly, i still get the same ERROR message in fastboot/recovery mode. Is that because the bootloader is locked?

In flashtool, when my device is in system mode, when i click "check drivers" in the "devices" tab, i get:

5) As we are supposed install stock rom (.ftf?) with Xperia companion (am I right?), i saw we can change manually the proxy setting.

Can we set it to localhost so it can use one specific .ftf located on a local harddisk?

I mean, if there a .ftf file on the root of C:\ , does Xperia companion will install it?

5) Even i saw 32.4.A.0.154 firmware seems to work with the Nimadroid kernel,with Xperifirm, i tried to find the SGP771 32.4.A.0.160,but there are only 32.4.A.0.154 versions.

Do you have a link where i could download the SGP771 32.4.A.0.160 advised in this topic?

6) if, at last, i can install a .ftf stock rom, regardless of the locked bootloader, could somebody make a light (lightest! :p) drm free, rooted rom with opengapp pico software? ;p

I suppose it is doable because , somebody did it on a motora defy .sbf file i used...

Sorry for asking so many questions but i really want to have a rooted drmfree stock rom in my device, even if i know i won't be able to install a Lineage custom rom...

Thank you
