Whoever is using this rom still, i suggest you stop and flash los17.1 instead.
Indeed! I have been able to successfully upgrade directly from the 17-07-19/16.0 version to the newest 10-04-20/17.1 version on my Galaxy S9 (960F), keeping all my apps and settings and without any issues.
Maybe this will help someone:
1. Make sure your TWRP version is 3.2.3.0--if it's older/newer then upgrade/downgrade to 3.2.3.0 by going to https://eu.dl.twrp.me/starlte/ and grab the twrp-3.3.0-0-starlte.img file. Use your current TWRP version to flash this image file. Read more about TWRP here: https://xdaforums.com/galaxy-s9/samsung-galaxy-s9--s9-cross-device-development/twrp-exynos-t3763464
2. Flash the new Q BL (Bootloader). I've grabbed the BL_G960FXXS7DTB5.zip file from https://mega.nz/folder/oFJ1nK5Z#eWD2AU4CQxWSdA_kxxRkHA/folder/QFZhxKqI. After installing the new bootloader my phone wanted to reboot. This wasn't a problem: the bootloader booted the 17-07-19/16.0 version without problems.
Note: there's also a vendor.img file in the same folder, but you do not need that one!
3. After booting into in Recovery (TWRP) again I've used the Advanced Wipe option to *only* wipe the Dalvik/Art Cache and Cache partitions.
4. Still in Recovery (TWRP) I've flashed the file G960FXXU8DTC5_vendor.img file that I've grabbed from https://mega.nz/folder/0McClQKJ#ic8c0LEYF3zGSo_Ivv1nSw/folder/MdNGlACQ (source: https://xdaforums.com/galaxy-s9/samsung-galaxy-s9--s9-cross-device-development/rom-t4075725)
5. Still in Recovery (TWRP) I've flashed the latest 17.1 ROM version that I had downloaded from https://mega.nz/folder/0McClQKJ#ic8c0LEYF3zGSo_Ivv1nSw/folder/gcMkHK4T. Read more about this new ROM here: https://xdaforums.com/galaxy-s9/samsung-galaxy-s9--s9-cross-device-development/rom-t4075725
6. Finally, still in Recovery (TWRP) I've flashed the Open GApps that I had downloaded from https://opengapps.org/. I had selected: Platform ARM64, Android 10.0, Variant Nano
Rebooting the first time took some minutes to complete. The next time the phone boots fast as always. And everything works great!
