Thanks for your support!

The installation of this ROM is easy even for me at 73. It is stable and fast. I started testing it. Best regards and thanks to the developers.

 

[lorisino]

Thank you I'm going to try it

I am unable to boot this ROM on castor_windy. ROM will flash fine but I get the red LED flashing when I try to boot.

I upgraded to 18.1 from Lineage 17.1 after formatting in TWRP and flashing the recommended rom and gapps. Has anyone tried to root? Magisk 20.4 (which to my understanding is the only compatible root with Z2 stuff now) refused to flash in TWRP, so I then tried the latest magisk. Now I am stuck in a bootloop of the Sony Boot screen. I've attempted to reflash TWRP 3.4 and although it flashes successfully, the sony bootloop remains. Maybe time for a factory reset. Its been so long i don't even know where those recovery images are anymore.

EDIT: I forgot to thank @qsnc for support on this. Pretty unbelievable that this tablet is still kicking. Much appreciated.

EDIT2: Flashing the stock boot image from the rom has me booting again. Would still like some input on root possibilities from anyone out there.

First of all, thank you @qsnc for your hard work to keep our device alive.

@bacon612: Getting Magisk to work is a bit tricky on this device. Look at the bottom of the following discussion on github, it worked for me: https://github.com/topjohnwu/Magisk/issues/3636

Installation is possible, coming from AICP 15.0. I've done all wipes, but after restart only a blinking red led comes up.
Whats the problem? To have a working system back i flashed the boot.img from 15.0 and the recovery from twrp. Than I restored my backup....

Good evening, I tried the rom is very nice and fast, despite having performed the whole procedure I can't get root permissions.
I have flash magisk 21.4 does all the installation without errors in the reboot I do not have root permissions. Hope it can fix this bug. Thanks I apologize for the bad English.

Hi, the standard package of Magisk will not work. Check the GitHub link in Post #7, you will find a modified Magisk 22.1 package for Sony devices there.

Thanks for the advice. Reading everything no one speaks for xperia tablet castor_windy Lineage 18.1. I did some tests but with negative results. I also tried to rename magisk 22.1 in zip then flash with twrp 3.4.0 sc1 does all the installation without errors in restarting the tablet is as before without root precautions. It's a good fast rom and I wouldn't want to go back to 17.1 How can I solve? Thank you

that should solve the problems people have been having with magisk. no support here for such things though guys, so please keep on topic.

 

[Jo_alfa]

Thanks qsnc this evening I will try it and I will keep you informed if everything went well. Thank you

 

[Jo_alfa]

Updated with builds for April 26. Especially for Windy users: please contact me with feedback.

 

[qsnc]

no windy users?

 

[JP_TouchDiamond]

Hi qsnc, I have just flashed the new ROM on my "windy" device and everything works fine. I am typing from a bluetooth keiyboard and I am using a bluetooth mouse. No issues with the installation. I will further test the image during the week.

 

[covester]

Windy user here! On this build and the previous one, NFC and Android Beam are constantly and repeatedly switching on and off. Otherwise, I haven't noticed or experienced any other issues. Thanks.

I stayed on 17.1 for now as I'm using MicroG so it's a non-trivial upgrade for me and I don't have the time to do it now. I do appreciate your work though. Thank you!
