Hey Guys -
To apply a ROM to my HTC One A9, it requires I set aside about 3 hours of time. Since I choose to use my microSD card as "Internal Storage," I must follow a specific set of sets to apply and root the rom or else formatting & use of the SD as Internal Storage fails. An overview of these steps are...
My Question
Recently, I got notification on my phone that a new OEM rom was available - 1.57.617.52 (AT&T phone I converted to DEV) and I've already downloaded the full rom to my PC. Before wasting tons of time doing the above, I wanted to see if there was a way to upgrade to the new rom on my phone and either maintain root or really just any procedure where I didn't have to do the long list of steps above.
I recently read a bit about the fairly new FlashFire, but don't know if it could be used in this scenario or is even compatible with my phone. Also, despite having downloaded the updated rom from HTC, even if I wanted to upgrade via TWRP and follow above steps, I'd need the full OTA instead, right?
Overall, if anyone has a suggestion for the easiest way to upgrade in my situation, I'd really appreciate it! If it does require a full OTA, if you happen to know of a link for 1.57.617.52, I'd appreciate it. If not, looks like there will be a backup, wipe and half a day of fun in my future... :)

- Apply desired rom to phone
- Root with latest SuperSU
- Take backup of boot partition via TWRP
- Using Android Image Kitchen, extract boot partition from unmodified rom
- Replacing verity key and couple other things in the backed up, rooted boot image from the extracted unmodified boot image
- Reflash newly modified boot image via TWRP
