Oxygen OS 2.1.4 Downgrade? - ONE Q&A, Help & Troubleshooting

Has anyone around here flashed OOS 2.1.4 using the recommended method and then flashed a different rom, Im tired of using OOS but i cant seem to find a way to flash CM13 again.

Just flash cm13 in a version of twrp with working firmware flashing. The firmware is included in official cm13 builds.

install TWRP again, and download and flash cm13?

Yes, as long as it's an offical build and you have a version of twrp that supports firmware flashing, like 2.8.6.0 or 3.0.0-1, it will flash everything it needs. If you flash something like sultans bulids flash offical cyanogenmod first then flash the modded build.

Hello!
First of all I'm sorry I'm late to the party ?.
I bought my OPO yesterday and I'm a newbie with all the flashing and so on. It happens to run Oxygen OS 2.1.4 as well and I was wondering if anyone could give me (a link to?) a tutorial to flash a new recovery and everything? I'd really appreciate it.
Thanks in advance

After this,you should be considering this one as OOs 2.1.4 is pretty outdated: https://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541#login

Do a full wipe and just flash OxygenOS. There's no reason why it'll fail. I've been hoping around OxygenOS and other ROM for a number of months and I never had that issue. Use TWRP 2.8.6.0 to flash
OKay my fault. I missed to unzip the downloaded zip file.
Now I got it

Trouble updating mi-globe rom

Hello! I have been using mi-globe & previous smiui for quite some time and never had an issue with dirty flashes. Now, I try to install 6.12.22 over the 6.11.24 version and I always get an "Updater gave an Error 7" and the update fails. I want to flash 6.12.22 to prepare myself for android 7 update. I have also tried to flash 6.12.15 version and also fails. I have tried with TWRP version 2.8.7.3 and later with version 3 which also fails. What can I do ?
Weired...
Are you sure you took the right one? DL again via a computer?
Your nov. build should have the last TWRP version. Did you tried to update it via fastboot?

You have this TWRP :
https://www.androidfilehost.com/?fid=529152257862699043
Or team's superluminal one? (this one I think.. https://www.androidfilehost.com/?fid=24421527759888487)
Did you try to install the same version on Xiaomi.eu before, and just flash over the Mi-globe twice?

thanks for the help but i succeeded by dirty flashing xiaomi.eu 6.12.22 over mi-globe 6.11.24, for some reason it worked. I don't know which one recovery I have, i flashed the 3.0 version using the TWRP app from tha playstore, I don't know which of the two is this ( I think the file I flashed was around 45mb so it's probably the first...).
UPDATE: I have the 3.0.2 TWRP version. Is it compatible with nougat ??
I'm not sure it's about the number only. On the mi-globe topic, it's explained. Flash nougat. Then unlockdevice, then flash twrp compatible

Upgrade my OPO to latest build

I see threads on how to downgrade but none explaining how to upgrade to latest build. Most threads are years old 13.1.2-ZNH2KAS3P0 being the latest i could find
My phone came with V.6.0.1. Cyanogen OS v. 13.1-ZNH2KAS1KN.
why not custom roms ? like lineage os , resurreciton remix etc.
The best way to upgrade is via a custom rom.
Follow this: https://forum.xda-developers.com/showthread.php?t=2788632
13.1.2-ZNH2KAS3P0 indeed the latest official version. If you want to get further updates, only customized ROMs can help you with that.
That was what I was trying to do was install custom ROMs, both new and old failed with TWRP error 7...so i figured there was an update i needed before i could install them. I installed 13.1.2-ZNH2KAS3P0. Still no go...
I already had followed that threads instructions but all ROMs failed. TWRP error 7.
I was finally able to install a ROM. Lineage-14.1-20170814-nightly-bacon-signed https://download.lineageos.org/bacon I am still confused as to why this one worked and the others didn't though... now I am too paranoid to flash any other ROMs until I figure this out .
Any explanation or advice would be greatly appreciated I Hate not understanding how I did something lol. Thanks for all your help!
once you follow the Lineage Os guide your unlocked and good to go. I usually sideload the install using TWRp..

If you want to switch to a completely different ROM, you will have to do the wipes in recovery then flash the new ROM. If you want to flash an update of the same ROM you have then you don't need the wipes, you can just flash the update without wiping, this is called "dirty flashing". Dirty flash usually only works when flashing an update of the same ROM that you have.

Hello ,
I am talking about the cm14.1 latest firmware and not about the custom room updates. Is it possible to install without any issues
Thanks in advance

What do you mean the latest CM14.1 update?
NitrogenOS and CM 14.1 ARE BOTH custom ROMs, they are NOT firmwares. Some devices were manufactured and sold with CyanogenMod as the stock firmware but CM is still predominately a custom android operating system.
And, as I said, if the update is an update to the exact same ROM as what is already installed, then all you have to do is flash it without doing any kind of wipes(this can even be done when updating stock via OTA, it's actually recommended to not do the wipes when updating stock via OTA). For example, if you have CM13 and want to update to CM14, or if you have CM14 and want to update to CM14.1 or if you have CM14.1 but want to flash a newer CM14.1 update, understand yet?
BUT!!!!
If you have some other ROM(something other than a version CM) currently installed but want to update to CM instead of what you have then you would have to factory reset, wipe cache and dalvik cache before flashing.
Let's make this simple since you can't seem to make sense of what I'm telling you. Tell me what you currently have installed and what you want to update to.

You have nitrogen OS installed on your android and if you want to install update of nitrogen OS then no need of wiping.
If you want to change to different rom ( nitrogenOS to CM) then you need to first wiping/factory resetting or clearing dalvik and cache.
So, you are changing your rom then wipe/factory reset first and then flash CM. That what @Droidriven trying to say you.
Again you are confused. ROMs like Nitrogen runs on CM firmware ( or you can call it architecture). It's not the OS again, It regarding firmware. please someone help me on this I dont want my phone to get bootlooped or any other sort of issue. FYI : I don't want CM ROM/OS. I want Nitrogen itself but want to upgrade to the latest firmware. Please check the link i had provide before replying

This is making sense now. You see, you are the one confused. You aren't asking the right question because you don't understand the difference.
You aren't looking for the "CM firmware", this does not even exist. This implies that the firmware was created by CM. It wasn't made by CM, it does not contain CM in it so it can't be called "CM FIRMWARE", it's a STOCK FIRMWARE that is COMPATIBLE with USING CM and other custom ROMs.
What you are looking for is the "stock firmware" that needs to be on your device BEFORE using CM13/14/14.1/AOSP Nougat ROMs.
The thread that you linked basically explains that if you want to use any kind of custom 7.0/7.1/7.1.1 Nougat ROMS then you need to flash this updated STOCK FIRMWARE in order for the device to be able to use those custom ROMs. It is not "CM FIRMWARE"
You're looking for the STOCK FIRMWARE that is compatible with CM and other nougat ROMs.
The thread that you linked explains what you need to know and how to do it, it says that you flash the updated firmware via TWRP and factory reset, wipe cache and dalvik when you flash it.
If you are looking for a newer update than the one in that thread then you'll have to find it in a TWRP flashable .zip. If there is not a TWRP flashable zip to apply the new update then the only way to flash the new update is to flash it via PC then root the device again, install TWRP again and then flash your NitrogenOS ROM again.

I just explained what you needed to do, did you read it? It is simple, are you even reading the thread that you linked? What you are asking is irrelevant, just do what it says to do in the steps below.
1) Boot to TWRP
2) Flash the updated firmware via TWRP
3) Factory reset, wipe cache and dalvik
4) Flash NitrogenOS
5)reboot, enjoy.

Download and flash: https://forum.xda-developers.com/attachment.php?attachmentid=4302781&d=1508010356
You should now be rooted with Magisk.
Make sure you have TWRP 3.1.x from the twrp thread

Is it really that easy? i have mine rooted with TWRP 3.1, i can flash that file and I'll have magisk? I'm on the same HW/SW version as the OP.
since the Oreo is coming out, will I need to flash stock to get the Stock Oreo update when its released? I assume so. I am new to the Mates and they seem to have a much different flash method/path than the Nexus 6p and HTC devices i have done in the past. I'm kind of leery to pursue Installing ROM's and Magisk (never used it yet) but would like to. Any tips or links to detailed instructions for the Mate flashing? I cant find, what I feel, to be detailed instructions on XDA.
thanks

If you're rooted with SuperSU or Phh you will need to restore your stock boot image before flashing Magisk,
this can be done by downloading your firmware from http://pro-teammt.ru/firmware-database/ then extacting update.app and opening it in Huawei Update Extractor where you extract BOOT.IMG.
Flash it using fastboot flash boot boot.img.
As long as you're using firmware B182+ (Loop device support) and TWRP 3.1.x you can install official Magisk/SuperSU.
Oreo will be a full firmware so it shouldn't need to verify any partition, meaning you will only need to restore stock recovery.
