Upgrade from custom ROM to Android 7.0

Hi guys,
Not sure if this is the right place to post this but unless I am missing something, I have yet to find a thread or instructions on how to do this.
I am on Pure Nexus, but I posted here because I'm guessing the answer applies to virtually any custom ROM. What are the steps involved in upgrading from a custom 6.0 ROM to the newly released Android 7.0? Is there a way to do this while keeping root?
Thanks,

There's roms you can flash, other than that just wait for the images to release and there will be alot options

So if it's a custom ROM based on 7.0 I can go ahead and flash using that specific ROM instructions?
I thought the official 7.0 came out yesterday, that's why I was wondering if I could update to the official and keep root and how to do that.

I'd Mae a backup send it to PC and try tupac4us rom or digitalhighs . They have vendors built in the zip .

I was on Benzo rom and this is exactly what I did; I restored back to stock rom only leaving bootloader unlocked. I joined the Android beta and the N ota was ready to install. I then flashed the latest twrp. I made sure to do a full nandroid and physically backed up anything important to my laptop before I restored to stock. I noticed until I flashed ditialhighs N rom my twrp would not "stick" but no big deal I just flashed it and went into recovery. It seems Android Pay is working with digitialhighs rom, you just toggle off root, use it, toggle back. Good luck

Which guide did you use for restoring to stock while keeping the bootloader unlocked?

i was on pure nexus 6.1 i used this guide to revert everything back to stock then i subscribed to the developer program and got 7.0 update in seconds, section 14 is pretty much all you need

the best rom

hi what is the best rom for zuk z2 pro?

AICP ROM oa CM froh Emmaus

and the mokee?

Is there a rom (pure or almost pure) that works well in zuk z2 with ota?

I'm waiting to get my phone and it's said it has Global rom. Is this rom good or should i change to other?

Sadly, stock room is the best as for now

You should probably flash another ROM. Either the stock one (which can be set to English but comes with A LOT of chinese apps and bloatware) or AICP / Mokee.
The "international" ROM that comes with your phones is most likely a modified ROM installed by the shop, which will be outdated, will not receive OTA updates, and might contain malwares. My Z2 came with a ROM on which the keyboard didn't even work at all, so I could not connect to the wifi, register my google account or anything untill I flashed a new ROM via USB.

I had that problem too. fixed it with changing keyboard language to norwegian.

Moving to LineageOS worth it (and possible) from Cloudy G2.2?

I've been running Cloudy G2.2 for a year an a half. It's given the phone enough legs to mostly make it through 2017. However, about every other week I have to restore my latest backup when Bluetooth stops working because it saw too many devices. This wouldn't be terrible if it wasn't for Authy refusing to sync my newer 2-Factor auth accounts. I think I've convinced myself that the G6 (US997) is my next phone, but now is a silly time to buy as the price should drop like a rock as the next wave of flagships come out.
I'm hoping to make it another couple months and was wondering anyone's experiences moving from Cloudy G2.2 (or other ROMs) to the latest lineage? From what I've read, it's very stable. However, I'm on Kit Kat bootloader, so it doesn't seem like this will be a straightforward process. I was hoping to get some experiences from people who made the same move before starting.
I currently have:
LG G2 D800
Root using stumproot (I think, it's been a while) with supersu installed
TWRP 2.7.0.0 installed by autorec
Cloudy G2.2 KOT49I

So, after some research, I set off to install LineageOS. In hindsight, this might have been a bad idea since it specifically only mentions the D802 in the title. However, it listed links for D800 builds, though they were crossed out.
I updated TWRP to this version by Blastagator and that was painless. I then wiped the phone, made a fresh backup and flashed the latest nightly of LineageOS, and the latest GApps (Mini) for 7.1. That was disappointing since I got the quick "LG logo" followed by a blank screen, that I later found was mentioned in the same Lineage post. Should've read farther.
I think the issue is that I'm on the wrong bootloader. I thought I was on KitKat which the post requires, but in order to enter recovery, I have to press enter three times (rather than using volume buttons to navigate), which indicates I'm on JellyBean bootloader.
So, this is the scary step that I was hoping to avoid. My big fear is that I run Linux on my desktop, so I can't use the LG Flash Tool. As long as I can keep a working recovery, I have backups, so I'm fairly safe. Following the Blastagator bootloader post, I'm not really sure how you go back and forth between bootloaders so easily as it suggests. Is that really as simple as loading the zip file on the phone and installing it in TWRP?
Is there a safer way to handle this?

From my experience, it is that easy. Simply install the zip file and you have loaded a new boot loader. Also, I was in the same boat as you with Cloudy rom and moved to Nougat with crDroid. However it's not stable and I am considering looking for something else more stable but fast like crDroid.

When you updated your bootloader, were you still able to run the Cloudy ROM before you switched to crDroid? Once I flash the KitKat bootloader, am I only able to use the Nougat ROMs? My big concern is that there might be something a bit off with my bootloader, so I won't be able to get back to TWRP.
I think there's something a bit off with my bootloader as is, because about a year ago I flashed back to stock Jellybean, and took all the OTA updates. However, when the phone tried to take the KitKat update, it softbricked, and could only be recovered using the LG Update Tool, which I don't have access to anymore. Because of this, I'm a little worried that just dropping on the Blastagator KitKat bootloader may have some atypical issues.

i m using it for a while. u know, on Los you won't be able to use lg features such as qslide, qmemo, plug&pop, knockcode etc. Only worth it if you want your phone to look a little bit fresher and lighter or you need a newer android version for some reason. Else, don't take the risk if you can't use flashtool. You can consider installing another kitkat rom. There are lots and they are nice :]

My primary issue is that KitKat (or whatever Cloudy G2.2 is?) has the old Android bluetooth bug where once it sees too many devices, it stops connecting to anything. I have to make sure to turn off my phone if I go somewhere like an airport, and have been having to restore my clean Cloudy backup about once a month. It's getting pretty frustrating. On the other hand, I'm hoping to upgrade to an LG G6 (US997) in a month or two when the V30 release pushes down on prices. So, if it's a case of potentially hard-bricking my G2 at the worst possible time, I should hold off flashing.

I think you need hybrid bootstack for android 7.

That makes sense, but will I not be able to use my Cloudy 2.2 backup after that? It says that the hybrid bootstack will only boot CM 12.1, CM13, and LP stock roms.

These questions if this works with that or that are easier to answer for yourself by reading what goes with what.
Just Google LG G2 bootstack and you can probably find the ones you need for any available rom.
I use hybrid on Marshmallow 6.0.1 but I tried Nougat 7.1.2 too, it works.

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

Stock Zuk Z1 inquiry?

Our zuk z1 is installed with los 16.0 and me and my dad is planning to return to stock,, no root no mods locked bootloader, but there are 2 OS for z1 which is COS lollipop and the zui... We just want to install the stock rom with working playstore plain stock no additional fuss... Which one should be? Zui is the updated one with nougat so when we flash that one will it become locked like factory default ones?
