TWRP 3.3.0+ for SGP621? - Xperia Z3 Tablet Compact Q&A, Help & Troubleshooti

Been looking all over the forums and run into some dead ends and old threads, so I though I'd straight up ask instead. Is there a TWRP 3.3.0 (or at least newer than 3.0.2) for the SGP621 (LTE variant) available somewhere? Or do I have to tweak the ROM zips somehow to make them flash using the official TWRP 3.0.2 for SGP611?
Specifically, I'm trying to install the LOS15.1 ROM, coming from Floko ROM. SO I must have had a working TWRP at one point, but I seem to have lost the files and LOS15.1 flashed over the one on the device...

Me too. The whole Internet has nothing available

It works with 3.0.2.0 - 3.3.0.0 does not exist for scorpion windy
Step1: Flash the TWRP in the boot partition, as reported in the quoted message (unlocked bootloader necessary).
Enter Fastbook mode by pressing VOL down and plugging in USB cable to your PC.
Code:
fastboot flash boot twrp-3.0.2-0-scorpion_windy.img
Step 2: Edit LineageOS zip file
Trying to flash the lineage15.1-20190922-unofficial-z3tc.zip indeed outputs ERROR 7 in TWRP, failing the installation. I solved this issue. (Edit the contents of /META-INF/com/google/android/updater-script to the text pasted below this instructions. Try to edit within the zip wothout expanding)
This solves the issue reported in the quoted message, which was solved mentioning the use of TWRP 3.3.0-0 which actually does not exist for this device.
Step 3: Final installation process
Reboot to recovery mode:
Code:
fastboot reboot recovery
Flash the edited .zip file of LineageOS
Flash GApps and SuperSU or Magisk (v18 worked in TWRP, not 22, but you can update later from Magisk Manager)
Step 4: Fix Recovery partition
After OS installation, you will not be able to reach the recovery again, as it was installed in the boot partition. Hence, reboot in fastboot mode, connect to the computer and run:
Code:
fastboot flash recovery twrp-3.0.2-0-scorpion_windy.img
updater-script. Replace existing content with this:
ui_print("Target: Sony/SGP611/SGP611:6.0.1/23.5.A.1.291/3706784398:user/release-keys");
ifelse(is_mounted("/system"), unmount("/system"));
package_extract_dir("install", "/tmp/install");
set_metadata_recursive("/tmp/install", "uid", 0, "gid", 0, "dmode", 0755, "fmode", 0644);
set_metadata_recursive("/tmp/install/bin", "uid", 0, "gid", 0, "dmode", 0755, "fmode", 0755);
mount("ext4", "EMMC", "/dev/block/platform/msm_sdcc.1/by-name/system", "/system", "");
run_program("/tmp/install/bin/backuptool.sh", "backup");
unmount("/system");
show_progress(0.750000, 0);
ui_print("Patching system image unconditionally...");
block_image_update("/dev/block/platform/msm_sdcc.1/by-name/system", package_extract_file("system.transfer.list"), "system.new.dat.br", "system.patch.dat") ||
abort("E1001: Failed to update system image.");
show_progress(0.020000, 10);
mount("ext4", "EMMC", "/dev/block/platform/msm_sdcc.1/by-name/system", "/system", "");
run_program("/tmp/install/bin/backuptool.sh", "restore");
unmount("/system");
show_progress(0.050000, 5);
package_extract_file("boot.img", "/dev/block/platform/msm_sdcc.1/by-name/boot");
show_progress(0.200000, 10);
set_progress(1.000000);

Hello, sorry that my language is translated by Google. I have successfully installed LineageOS ROM, but I found that there is no Google component. Therefore, I plan to rewrite Google-related components (GApps) through TWRP. The current situation is that I can only open TWRP but cannot enter ROM. At the same time, I don't know why, the TWRP installation directory shows that my storage and SD card storage are 0MB. Therefore, my Z3TC is currently unavailable. Is there any solution? Because I am trying for the first time, it may be a very elementary question.
Regarding other issues, currently my Z3TC cannot enter the green light mode, nor can it be connected to the computer to drag and drop files and only displays an icon. Therefore, I have no way to write to the official ROM.
