Sorry for the late reply, but i just saw your post in the developer's forum (Cpasjuste's Thor Gapps), where i cannot post due to my lurker nature.
i'm on the same FireOS version as you: 13.3.2.1
i had trouble getting Cpasjuste's ROM to work, because i was trying to use thor-gapps-13.3.0.0-v2. i didn't dare using thor-gapps-13.3.2.4-v1, because of the several warnings.
i then saw someone else having success with thor-gapps-13.3.2.4-v1 on an earlier version and thought i'd give it a try after all. i took the risk of closing the door to an unlocked bootloader, i took the risk of bricking my device. i decided to do this, because of my year long experience with custom ROMs, also on devices that were not intended to have them (Nook HD+, Kindle Fire...). i'm not sure, if the kernel is touched during the flash process, but i
assum(ed) it isn't. i can boot into FireOS which still shows 13.3.2.1 as version, but who knows what has happened under the hood.
The ROM feels stable so far for such an early version. i haven't tested much, but the few apps I've been using regularly worked well. Ironically the amazon appstore crashed after about 20 seconds. Makes me think they are trying to block the "freed" devices, but it might just be a bug after all.
So, again, if you feel like risking to lose the possibility of an unlocked bootloader, if you want to risk or can afford to brick such an expensive device, you can try using thor-gapps-13.3.2.4-v1.
All i did, was to follow the instructions provided in Cpasjuste's thread exactly as they were.
Don't hold me accountable, it's already been a week, but if i recall correctly, these were my steps:
- DIsable WiFi / Enable Airplane mode in FireOS (just to prevent automatic OTA updates)
- Root device (i used towelroot)
- Install Safestrap (i had to use Safestrap-Thor-3.75-os3.2.4-B02.apk, despite the instructions in the safestrap thread telling to use 3.72 on our version - another risk i took)
- Boot into Safestrap
- Backup Original ROM
- Create ROM Slot (keep this new slot active/activated)
- Restore Original ROM backup, but only the DATA partition
- Wipe Cache + Dalvik Cache
- Flash thor-gapps-13.3.2.4-v1.zip
- Wipe Cache + Dalvik Cache
- Boot into system
