D802 update from CM12.1 to CM13

Hi, I'm currently running CM12.1 on my LG G2 D802 and I'm planning to upgrade it to CM13. I did some research but since I'm a newbie I would like to ask for some confirmation that following steps are correct:
Download and store following files in device memory:
TWRP BUMP Recovery: http://forum.xda-developers.com/lg-g2/development/twrp-twrp-2-8-0-0-kernel-f2fs-tools-t2898705
Hybrid Bootstack: http://forum.xda-developers.com/lg-g2/development/boot-g2-hybrid-bootstacks-t3183219
Latest CM13 Release: https://download.cyanogenmod.org/get/d802-snapshot.zip
GApps for ARM/6.0: http://opengapps.org/
Reboot to Recovery (currently TWRP v2.8.6.1 )
Flash TWRP BUMP recovery
Reboot to Recovery
Flash Hybrid Bootstack
Reboot to Recovery
Create a backup of currently running system (CM12.1)
Factory Reset
Flash CM13 and GApps
Reboot to System
Did I miss something?
It worked.
Thanks for simplified steps... the ones shown in the Official CM13 thread were a bit confusing. Going to try this now myself
Just some feedback, this worked 100%. Thanks again
i perfer to do a full wipe. factory reset then wipe dalvik, system, data and cache but leave internal storage alone.

Issue upgrading from oxygenos 4.5.14 to 5.0.2 on formerly rooted device

I have a formerly rooted OP 5 currently running oxygenos 4.5.14(this was dirty flashed from a rooted 4.5.3 device) and wanted to upgrade to 5.0.2 without losing my data. I have lost the root and that's fine. I am trying to upgrade to 5.0.1 or 5.0.2 and the update keeps failing. Anyone have tips or guidance on how to proceed?
unless you relock your bootloader you won't be able to update. i tried everything. make sure you backup your data before you relock bootloader beacause this process will wipe everything.
cmd code to lock bootloader - fastboot oem lock
alternatively you can try this but i haven't tried so i won't recommend this method - https://forum.xda-developers.com/oneplus-5/how-to/guide-upgrade-nougat-rooted-encrypted-t3734779

would you recommend this if I just follow this tutorial up to step 8? I'm on 4.5.14 and would like to update to 5.0.2 even I lose my data and internal storage.
Step
Always succeed to upgrade in my case and not losing any data, maybe my way can help you
1. Instal codeworkx twrp not bluspark twrp, if you already have codeworkx just ignore this step
2. Wipe dalvik and cache
3. Instal update (full zip not partial zip)
4. Wipe dalvik and cache again
5. If you want to root, instal magisk 15.2 (recommended) and if you don't just ignore this step and reboot
6. Wipe dalvik and cache again (last time)
7. Reboot and enjoy your update

To elaborate some of these steps:
1. Boot to fastloader and install codeworx twrp
2. Boot to twrp (codeworx) then wipe dalvik and cache
3. Flash the signed zip (5.0.2)
4. Wipe dalvik cache
5. Install magisk zip
6. Wipe dalvik cache
7. Boot to system
Is this right? What should I do if I have xposed modules and magisk modules currently?

Try with latest TWRP and backup your current rom
1) download pie rom and save it to your SD Card or OTG Pendrive
2) if you are from stock rom, possibly its partition is ecrypted, you need to wipe data partition first
3) wipe the system, data, cache, dalvic cache, vendor,
4) flash the rom and gapps and wipe dalvic cache, cache again
5) reboot to system
i am just sharing latest TWRP link, i didnt tested it, if it works please reply here. it will help others

Problem installing omnirom android 9 on oneplus 5

i follow the instructions as per omnirom thread... flash the vendor/firmware, wipe data , reboot recovery, and flash the rom, but the omni rom does not boot at all and just shows the OMNI sign on/off. How should i proceed?
Which ROM were you on? What Firmware were you on? Were you Encrypted? Did you only Wipe /Data or did you wipe everything?

Lineageos 15.1 (android 8.1)
I first flashed OOS stock firmware, then OOS, then LOS.
I format data and then wipe dalvik cache, cache, data, system.

Is your Recovery up to date? I'd recommend the latest Codeworkx TWRP. Did you already have the Vendor partition on your device before attempting to flash Omnirom?
If in doubt flash full OOS 5.1.3 and OTA all the way up to and including 9.0.1. Then reinstall TWRP by fastboot, wipe and format everything and then flash Omni.

I still tried, it does not work. My phone got bricked, so I used MSM tool to unbrick and after that I got Nougat 7.1.1. I upgrade my Android to 8.0 (OOS 5.1.3) from system update, and after that update another one came, Android 8.1.1 ( OOS 5.1.7). I then unlock bootloader, flash twrp, flash vendor/firmware, wipe data, flash Omnirom but I get stuck into the omni loading screen. The phone does not load.

Okay, i'm not seeing anything about a Format operation there. Wipe does not equal Format. I've just finished setting up Omnirom 9 on my own OP5, so it does work. (Great ROM btw)
Backup everything from Internal Storage to your PC, including all the installation files. The following will wipe your storage!
1) Boot into TWRP
2) Wipe Menu, Advanced, Select all Partitions manually and Wipe
3) Wipe Menu, Format. (Type Yes when prompted)
4) Reboot Menu, Reboot Recovery
5) Copy Installation files from PC to Internal Storage
6) Install Menu, Queue up and install zips in the following order:
i) Vendor/Firmware
ii) ROM
iii) Gapps
7) Wipe Dalvik/Cache when prompted
8) Reboot
9) Set up and done.

I did it, but I get a bootloop. Omnirom does not boot, it just shows the OMNI logo lights.

The only difference between the two of us that i can see is that i flashed OOS 9.0.1 and booted into it once before doing the steps above.
Don't know if it's relevant but the Vendor/Firmware that i used was 9.0.1 also:

Make sure you nuke everything before starting. Wipe and Format everything. Move installation files across and follow steps.

I flashed OOS first and booted everything and I followed the steps and got everything right, but still I get stuck with a bootloop that does not load OmniROM.
Works fine for me;
Flashed the latest OxygenOS. Now you dont need to worry about flashing firmware later in the process.
Enabled unlocking the bootloader in developer menu.
Rebooted into bootloader and flashed the recovery image from clockworkx and booted into twrp recovery.
Wiped everything and formatted data as well.
Reboot recovery.
Flashed rom. I always use sideload but that should not matter. Dont flash anything else; first reboot into your working system.
