It would be nice to be able to flash back and forth at will, of course being GSM and Verizon capable at the same time with dual sim capability would be even better!
PS I have unlocked bootloader and I was able to OTA to 9 just fine. Some said if you unlock the bootloader it won't OTA, but mine did. They ma have changed it somehow not sure.
Never made a backup of the Verizon firmware, never wanted it in the first place. Only link I saw is here https://bluproducts.com/support/verizon.pdf
Apparently, BLU seems to do updates via IMEI - and it feels like a one-shot thing.
For example, I had the BestBuy dual IMEI model, which was a Verizon model that came with 8.04.04 (dual sim) - then December 2018 came around, it got "upgraded" to one-sim verizon. I then used the pie-beta to get back to dual-sim/no verizon.
When I used the roms floating in this thread to downgrade back to "stock" 8.04.04, I never received any OTA updates at all. Expected at least the December 2018 security patch, but nada. Contacted BLU and they said a pie upgrade will be coming in the future for Verizon phones.
It wasn't until you posted the official pie upgrade that got me a rom upgrade!
Unfortunately, a few days of enjoying official pie, my bloated battery caught fire spectacularly.
