Does updating Custom ROM require a factory reset ? - Samsung Galaxy S7 Edge Questions and Answers

Hi I currently use the custom ROM Renovate 2.1, and want to update to 3.0, which was just released on 22nd July.
So if I just want to update a custom ROM, do I still have to backup all apps with Titanium Backup, and do a factory reset with TWRP before flashing the updated custom ROM? Or can I skip these steps?

So I just did a dirty flash anyway, and it seems I didn't lose anything, but I just noticed that Xposed Framework is now gone.
Do I lose anything besides Xposed Framework after dirty flashing a new version of a ROM?
By the way, do people usually dirty flash when updating a custom ROM? Is it safe to dirty flash when installing a new version of a ROM?

Usually its specific to the ROM that you're trying to flash. However, as a reference, if there aren't any major features added, it's probably safe to dirty flash it. They'll hopefully indicate if you should wipe in the instructions, though.

[Q] Going back to 4.4.4

Currently running the latest/last Euphoria rom on my n4, prior to that it was factory OTA'd up to 5.1 so the radio is bang up to date I would imagine.
For nostalgic reasons, I want to flash Mahdi rom. Is it as simple as flashing the rom on twrp, or will I need to flash via adb the the newest 4,4.4 radio too? I don't want to run into wifi/signal issues down the road.
Thanks.
I recommend flashing TWRP and then the ROM. If you run into an issue, then start changing bootloadesr and modems.

OS replacement vs 'de-bloated' stock ROM?

Scanning the forum today, I came across this:
[ROM] Z.A.D.Mix7 -Stock Base Rom-

It looks like it would solve all the issues I'm having with my A7:
Enable multi-user mode
Enable on-screen buttons
Replace ZTE's built-in apps.
Is this a safer route to go in general than installing Cyanogenmod (when it's ready)? I've got CM on my Nexus 4, and yes, there's nice stuff there that's probably not here, but is a de-bloated stock ROM more likely to be bug-free? More likely for the camera and sound system to work fully? Also, will a debloated ROM allow for OTA updates - or allow for them to be sideloaded? I guess I'm asking, if I were to install this, what would be the procedure to get Nougat once ZTE comes out with it? Wipe and re-flash? Or wait for a de-bloated ZTE nougat ROM and flash that?
In order to flash a ROM on your axon 7 you need to unlock your bootloader which causes your warranty to be void and you can no longer receive OTA updates. Also if you are running a custom ROM you will have to wipe your phone before flashing an OTA update. However if you are running the stock rom you will probably only need to flash the update. I've tried both CyanogenMod and Z.A.DMix7 and honestly Z.A.DMix7 is definitely the way to go. In my experience using Z.A.DMix7 it seemed to be as stable as the stock rim and didn't have any major bugs. The only problem I had with it is that since it it rooted there is no way to log into Snapchat. How ever if you don't want root I think there may be an way to remove root from the ROM however I haven't tried it so I'm not sure if it'll work.
I use the debloated rom with android n-ify, xStana, and gravitybox and it is much better than the stock rom. I haven't tried the cm rom. You would have to flash the stock rom and recovery to get OTA updates.

Help needed for upgrade

Hi there,
I'm using 4.4.2 wanamlite 2.9 rom on a i9505 with twrp 2.8.
Recently I encountered lot of problems like modem not working properly, rebooting, videos playing in slowmo, no sound etc... weird stuff...
I'm convinced to upgrade to (lets say) marshmallow (any custom rom) but I dunno how to do it properly. So here my questions:
- should I flash the stock rom and start again with root / custom rom etc? Or...
- should I upgrade with odin to stock modem and bootloader first, and after that install a custom rom via twrp? Which way is the correct one?
Btw. Should I upgrade to lolli, marsh or 7.x? Dunno whats better. I'm using touchwiz with xposed framework. I dont need tw but i find xposed very helpful. Any advice or link to guides?
Thanx
Upgrade the individual components. In your case, that means recovery, bootloader, and modem via Odin. Your copy of TWRP is ancient and the newer versions of Android need a newer version of TWRP to properly flash them. Once you've upgraded the components, download any Android 6.x ROM for your device - since you want Xposed - and flash it via TWRP. Android 7.x ROMs are available for your device, but Xposed does not work on them, and I don't expect it to work any time soon.

Thanx Stephron.
Yesterday I updated via .img the recovery (TWRP 3.2).
Now I'll look for bootloader and modem. Should I use the stock ones or are on xda some threads with better modems and bootloaders?
I think I'm going for resurrection remix or for some aosp. Any experience?
Best and happy new year .

GT-I9505: Best Custom ROM and what order of installation?

Hello,
I have a GT-I9505 with an untouched Android 5.0.1 and I want to use a Custom ROM. Questions:
1. Which ROM is currently the best one available?
2. Can Anyone provide me a foolproof instructions / order of installing everything?
Thanks in advance
There are many tutorials on XDA on flashing a custom rom, it`s easy once you know how. YouTube also has some great vid`s to watch step by step.
My advice is 1st install a custom recovery like TWRP, concentrate on that first, you will need to download Odin software to flash TWRP to your phone, after that it`s as simple as downloading a zip rom to your sd card and flashing to your phone through TWRP recovery.
ALWAYS BACKUP your current working setup and read the entire rom description as SOME may have a few functions not working.
So far I have flashed about 5 diffrent rom`s to my i9505, all of which have been great, im currently using - [JDCTeam] Aosp Extended Pie Release 2.91 [9.0.0_r21] [unofficial] - with no problems.

Installing custom rom after pie update

I'm currently on stock pie Jan patch, and I want to install a custom rom instead because I'm fed up with stock bugs. I'm looking forward to install pixys os, but I have a question. Are there any additional steps to install a custom rom? I don't want my phone to be bricked and lose my IMEI.
I have flashed LOS 16 without problems after Pie update.
You can flash the custom ROM without any big issues. Not sure about VoLTE though, if it is something you are concerned about.
Make a low level backup so you can recover in case something goes wrong
