Having Trouble Getting Back to Sense After Converting to GPE

Okay, so the other day I decided to convert my HTC One M8 to a Google Play Edition (I mean the full conversion with OTA updates and everything, not just a GPE ROM). It was nice for a few minutes, but I immediately started to miss Sense, and I'm not a big fan of stock Lollipop like I thought I'd be. So, I used an online tutorial to restore back to Sense, except when I tried to install the custom Sense ROM I was using before the conversion (LeeDroid) via TWRP, I got an error during the install in AROMA that said "set_perm: some changes failed". Then the install failed completely. I tried wiping Data, Cache, and Dalvik Cache again, but that didn't help. Then I tried wiping the System partition, but that didn't help either. I also tried other ROMs like Android Revolution HD and SkyDragon, and those installs both returned similar errors. I can flash CyanogenMod without any problems.

I know that converting to Google Play Edition changes the partition sizes (specifically the System partition), but I followed a tutorial and successfully factory reset my phone via the stock Recovery...so the partitions should be back to normal. I also re-flashed the firmware version I had before (4.16.401.10), so that can't be the issue. But just to experiment, I also flashed an older firmware version (specifically 1.54.401.5) and an older version of TWRP (2.7.1.0) and then installed ViperOneM8 v. 1.6.0 (which is over a year old). For some reason, that worked just fine and I can run KitKat and Sense 6...but why won't Lollipop work?

I'm sorry if this is confusing, but in a nutshell, I can't flash any Lollipop, Sense-based ROMs. I get either a "set_perm: some changes failed" or "some symlinks failed" error during installation in AROMA Installer. I really don't know what those errors even mean, which is part of my confusion. Does anyone have any advice?

Help with converting to Otterx without a computer

Hey, guise! Would you look at that, my first post here is one asking for assistance.

Alright, I have a Kindle Fire first generation, and I'm thinking about upgrading it to OtterX. I've already been there, done that, and beaten the bush up ten times over with playing with that Kindle. It's currently running CyanogenMod 11, Otter version, with self modified partitions which I needed to change up again anyways to offer more System space and maybe more Data space, something I wasn't worried about when I repartitioned it last time.

Anyhow, I was wondering if there was any way to power through the conversion process without a computer, as I'm lucky if I ever get on the computer.

Thank you in advance, and I'm sorry for asking such a noob question.
