DOWNGRADING TO LOLLIPOP:: --- B151 from B331

I got it all sorted fellas.

Went to the 5X Repository. Downloaded the Stock 1.51 firmware. Placed the "update.app" from it under "dload" on sd card.

Opened up SuperSU on phone and went to settings to remove root and reboot.

After reboot hooked phone to computer and adb flashed the stock 1.51 recovery found in the repository. "same method as flashing twrp, only use 1.51 recovery.img instead"

Reboot phone again and then powered off.

Hold Volume up/down and power to restart and it updates form the 1.51 stock firmware on the SD card WIPING ALL DATA.

Now fingerprint and all factory settings are restored!

Thanks to all, and hope this helps others coming back from Marshmallow or CM13 like i did.

Figured the above was an important surprise for some of you... :) OP still valid

Hello Everyone! Im new to the whole Honor 5x thing, coming from an m8 now, and before that a nexus 6, and before that a z3 then before that an S4 and before that an HTC Evo 4G LTE... Along with some minors, LG Risio, Moto E, S5...

Im just happy to say that so far I really enjoy this phone! :) Within the first few days of using it on Lolipop, i was getting 1d 15h type battery life which if youve looked at the phones ive mentioned so far... Really..really..wasnt what I was used to. A Day? For sure, the htc would be at 18% getting back on the charger... and it would die at 10%... with how long id had it. But... A Day was doable.

Ive been looking for a phone for SOOooOOO long now that had good enough battery to last a day at max brightness... Tweaking kernels, and Installing various ROMS (all of them per device)... Crack Flashing, as some would say. It just became a hobby... Ive noticed many weird things about the community, to those reading... let me list them now...

1. People all of the sudden(within the last 2 years?) prefer stock android over anything, regardless of what additional features are being added... Such as battery life improvements, Multitasking improvements, theme improvements, usability improvements... People like stock android... hmmm?

2. People want to be nexus so bad they will theme other UI's to death, just to make it look like stock, generic android... hmm..

3. Battery life, while a common complaint, seems to be indifferent to how frequently people update their phones.. (note: Marshmellow EMUI has a multi core battery bug, listed on XDA under mods..) or what ROM they choose (note the most popular rom being one with significantly worse battery life than stock)

4. Security improvements are completely unnecessary to the community (note the most popular rom being one that hardly supports the fingerprint sensor)

5. No matter how many bugs (even those listed in OP) people will always flock to the latest update of android. And then subtly complain to the developer about the bugs they already know about..

Such a strange mixture of people...to be sure.

However what ive noticed here, is a complete lack of readily available information, so i am hoping some of you might be able to assist me.

TL;DR

So I succeeded in downgrading my phone from MM to LP, as the battery life thing is a legit problem for me, as much as it may not be for other people. However the fingerprint sensor has been disabled, and no longer exists in the settings list... nor is it part of the startup. (confusing to be sure, you would think it would be there, and just FC when clicking on it were there to be a bug, or if the OS didnt detect the sensor or something... it should still be there yeah? If i understand how it works...

Also I cant seem to flash a B151 rom at all, being on B33...3? <- marshmellow... and im assuming at this point that means i wasnt supposed to be able to downgrade... (oops)

So i got TWRP installed (whats up with all the random errors twrp is throwing? Assuming thats normal...?) and am awaiting a BMarshmellow rom to finish... Which leads me to...

Where are the Emui ROMS? Unless its closed... but if this rom maker can do it... ?

and also, is the fix to the battery life on marshmello noticable to those of you who also care about battery life at all?
