Hello
I have been exploring custom ROM options for my Teracube phone & wanted to see what others have experienced. While Teracube devices are known for their open-source friendliness; not all ROMs work smoothly out of the box. 
Some require additional tweaks for fingerprint sensors, VoLTE / battery optimization. If you’ve installed a custom ROM, which one worked best for you & what adjustments did you need to make? 
Additionally; I’ve come across conflicting reports about whether bootloader unlocking affects OTA updates or warranty status. Some users claim relocking the bootloader can restore stock functionality, while others warn of potential bricking issues. Checked Customizations - Teracube Community Alteryx Course documentation guide for reference .
What’s the safest way to experiment with ROMs without permanently losing stock firmware access?
Any additional insights or experiences from this community would be greatly appreciated!
Thank you !!
