Hi Pete, can I just dirty flash this in recovery (PBRP)?
That should be OK. I clean flashed because my test device was running Los4microg, but thereās no reason why dirty flash ***shouldnāt *** work. Iāll keep my fingers crossed 
Dirty flashed today from SD card, reflashed Magisk directly afterwards, rebooted andā¦ Hell yeah! Works fantastic. GPS not tested since no app with GPS functionality on board anymore.
Everything seems to work with one exception: when I enable Tracking Control most apps refuse to connect to the internet. Strange, because other devices donāt have this behavior. Regardless if I release all blockers. When I disable TC apps have webaccess again.
But all the rest is great. Thanks Pete, itās really an awesome job!

I emailed Sony Developer World and asked about the Japan-market tablets. They replied:
It is only possible to unlock the bootloader for certain releases. The flag that enables/disables bootloader unlock is set at the factory according to the operatorās preferences and JP models could potentially not have unlockable bootloaders.
So best to avoid those, I guess.
Running V1.13 without any problems for some weeks now, thanks once again @petefoth
I even managed to complete a Seedvault backup for the first time!

No one who his this problem, that Tracking Control doesnāt work? See 2 posts above.
Hi @petefoth
First, Thanks a ton for all the work youāve done on this build.
Iām trying to refresh my old tablet and I was hoping to install /e/ on it to replace the old Android 6.
Do you still take questions in case I run into some issue when flashing the device?
I do, but itās also worth joing the XDA Forums thread for LineageOS on this device
https://forum.xda-developers.com/t/rom-8-1-0-lineageos-15-1-unofficial.4540297/
People there have much more experience than me, and the first post has links to the recovery you will need

Thank you for your reply. So far, I didnāt even manage to unlock the bootloader (as you mention in a post on the xda forum, it seems to be the hardest part). I found the right usb driver (it took quite a while), fastboot detect the device, but when sending the unlock command with the unlock code given by sony, I get a failed message. Iāll check on xda if they have a solution for this (service info says the device is unlockable).
Edit: Tried again this morning and it worked on 1st tryā¦

So. I managed to install PBRP Recovery and to boot into it. But I have no idea what to do.
In PBRP, I go to install, select the boot.img from the e-1.13-r-20230725-CUSTOM-z3tcw (that i unzipped into the device), I select System Image et Swipe to Flash but then if I want to reboot, I have a warning saying āno OS installedā.
I have no idea what I did wrong (or did not do).
Edit: My bad. I had used the file in the unzipped āe.1.13ā¦ā folder, when I had to use the zip file directly. I flashed it now, but for some reason, the battery wasnāt charging while plugged into the computer, so I turned it off and plugged it to the wall, waiting for it to charge a bit before turning it on again (it was litterally at 0%). Iāll update when I turn it back on)
Are your instructions Copy the .zip ā¦ ?
not needed
donāt care about it
.
Yes, my bad. I edited my message to include the correction. I didnāt use TWRP since I installed PBRP directly with fastboot (petefoth mentioned that it was probably unnessary to install TWRP after all and they were right). I could load the zip file into the tablet internal memory while in PBRP and install it from there.
Thanks for your input.
So. I restarted it but I get the Sony splash screen (with green-red-green led sequence), then the /e/ loading screen. But then the screen stays black with an orange led. And I can tell the screen is on since backlighting turns on and off when pushing the power button. And if I hold the power button, I get the option to turn off or restart the device. Maybe I should try another OS, like Lineage, to see if itās a software issue.
Edit: I went back into recovery, wiped cached data, rebooted and it worked fine.
Glad you got it sorted with help from @piero - sorry I didnāt reply, I was away from my computer.
I hope you enjoy the ROM on your tablet
WARNING: I have this ROM installed, rooted with Magisk 26.1
Magisk offers an upgrade to 26.3 - as soon as I install this (tried several times) it ends bootlooping ending in recovery. Dunno what to do but since the ROM development ends here anyway (with /e/) I just switched off Magisk-updating for now.
Hey @petefoth1 I just flashed another Z3TC with your unofficial /e/ build, thanks for that once again!
On the weird side: I had to flash your unofficial LOS 4microg firstā¦
And I remembered that I had to do this once already on another unit.
Have 4 or 5 of these great devices running in my family now
And also interesting: on this one the app icons stayed to be the ones from /e/ and not the ones from Trebuchet which I use on the tablet. Once again thank you for that to Peteā¦
Hi @MaxO @Infinity @petefoth
The specs for z3tc state:
USB microUSB 2.0 (MHL 3 TV-out), OTG, magnetic connector
Are any of you using MHL at all? Does it work?
In my lager family are quite a few SONY TVs and so far I keep older Samsung S2 on stock with KODI as an app install, hooked do these TVs, which works just great. And I still have one Z3TC on stock for the same reason.
If MHL would work on /e Iād switch the Z3TC now, but so far I never got any LOS working with MHL, in +6 years.
As you can see, I also would have to ask, what TVs you got it to work ā if at all.
Cheers

Unfortunately Iāll not be able to help as I mostly use the Z3TC for reading comics. Never used a TV-output.
