Yes you can downgrade. But make sure to flash Old modem otherwise security will crash. Just clean flash (wipe everything except internal storage)

Installing cyanogenmod 12.1 for the 1st time so pls help
Hello I'm going to flash custom rom for the 1st time so I have some doubts........ If in future I want to change the rom then again do I need to flash the stock rom or I can directly install any other rom...... N after installing the rom, will my phone n SD card data lost?
Thanks in advance......
Hi anuj, if you want to change the ROM in future you can flash it without going back to stock ROM, but remember you can only flash same android versions, if you are on KK and want to flash a Lollipop ROM then you must be on stock lollipop for the first time, after that you can flash any lollipop ROM and also Marshmallow ROMs . If you are on stock KK then you can only flash KK ROMs.
Your SD card data will be safe, unless you format it. As you are going to install custom ROM for the first time, I will advice you to backup your SD card data and internal data too. Prevention is better than cure.
Let me know if you have any doubt
Hit thanks if you find it helpful

SM-A500FU Bloatware and stable custom ROM

Hi guys!
I have SM-A500FU and I'm using stock ROM 6.0.1 rooted. First I want to remove some system apps but I'm not sure on what to remove and what to keep. Do you have any suggestions on what is safe to remove?
Also I've seen that there is not any stable and full working android 7 ROM (correct me if I'm wrong) Is there any good 7 ROM out there?
Sorry if my questions are stupid but I'm trying not to brick my phone.
Thanks!

You can try the Resurrection Remix Nougat 7.1.1 Rom for your Galaxy A5 Sm-A500FU.
Resurrection Remix ROM
It was made for the SM-A500H but it will work with the "FU" too.
I installed it on my SM-A500FU two weeks ago without any problems.
The only thing is that NFC doesn´t work. But I don´t need it.
I hope this is " stable and full working " enough for you because i did not found a better Rom with Android 7.
If you want a more stable ROM with Android 8 you should try this:
LineageOS 15 ROM
You can remove every Google App from you Phone like Hangouts or GMail.
You can try my Lineage 14.1 ROM, which is android 7.1.2 nougat.
It is designed for a500fu
Lineage 14.1
The ROM is very stable and suitable to be a daily driver. Some features like NFC I haven't tested but should work, I only built this yesterday
Also if there are bugs please tell me.

Nrml flashing couldn't make any problem that to be said from nougat to oreo since for now they have same baseband ver. but for you definitely flash stock rom first(nougat) via adb or twrp both work fine. There is difference between baseband in mm and nouhat and will create problem to you in future

As the post above states ensure you flash the stock nougat ROM before flashing nougat custom ROM. Flash stock nougat, reflash twrp, wipe system, data, cache, ART cache and then flash custom ROM.

Thank you, helps a lot!
As others have said, I would like to say you should update to N. As otherwise you might face a few issues namely baseband and fingerprint. The problem is a big MIGHT but I would recommend updating first

You must flash BL+CL otherwise your Sim card won't work and you will have very slow GPS.
Everything that you need is on Resurrection Rom threed

Nope, you're good to go. Just flash RR-O like you would any nougat rom, and you'll be fine.
