Oxygen OS 2.1.4 Downgrade?

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After this,you should be considering this one as OOs 2.1.4 is pretty outdated: https://forum.xda-developers.com/oneplus-one/general/guide-return-opo-to-100-stock-t2826541#login

TWRP version issue : can't install cyanogenmod

Hello,
I have a perfectly working moto G 4g with cyanogenmod, and did the install very easily the first time. I am stoked with it so when my mother asked me for a new phone I got another MotoG 4G, and went directly to install TWRP and cyanogenmod... BUT :
- when I want to flash Cyanogenmod build zip, TWRP tells me the version is not supported by this cyanogen build.... apparently it wants version 0x411A and nothing else. The only version available on TWRP website is the newest 0.3.2.0 ....
- I have tryed another twrp version found online (a 2.7.8 not official) and it fails again to install Cyanogenmod, saying the TWRP version is not correct.
Where can I get the correct 0x411A version of TWRP ? Or is the message actualy is about something else ?
Best regards and thanks in advance for your help.

I was confusing Bootloader version and TWRP version. I used a tool found on XDA that has updated my bootloader.
Then i was able to install cyanogenmod but was stuck on the logo for the first boot.
Updated TWRP to the latest one and trying again, flashed darvin cache, and i am flashing nightly cyanogen+gapps.
I hope it'll work this time

Go to setting > about phone and see Baseband version.
If you're coming from CM13.1 make sure to wipe everything except internal storage.
Download the ROM again if possible (the version you have downloaded may be corrupted) from the Lineage os official site and gapps(micro or pico).
Flash the ROM first and then gapps.
Reboot your device.
If you want the Root access download the Su add-on from the Lineage website also.
Hope it will work.
Let us know.
Thanks.

Sorry... but i don't have any os in my oneplus one... he is empty exept zip the lastest version of official website and zip of gapps.

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.

This is to all of you, you can't apply stock OTA updates on rooted devices or devices that have TWRP installed. Stock OTA updates require an unmodified system partition(meaning no root, no Xposed, no root mods of any kind).
OTA updates also require stock recovery, not TWRP.
You can all try flashing any stock firmware for your device then wait for the update notification then try the update process.
To those of you that have TWRP installed, this is a good example of why it is so important to create a nandroid backup of your stock ROM before you modify anything on the device. If you had that nandroid backup, you could restore the backup, then flash a copy of your stock recovery, then unroot the device, then wait for the update notification, then you'd be able to apply the current update. Then after applying the update, root the device again and flash TWRP again, then create a new nandroid backup of the updated stock ROM and delete the older backup from before the update.

I am running Lineage OS 15.1 when it applies the nightly update I get this error.
So what you are saying is they updated to MIUI 10 which as what I can see updates to MIUI 8.8.30 which includes new code
that TWRP and Lineage cannot install over. Also there is this Xiaomi's anti rollback that is installed as well so I am guessing
either live with the last Lineage OS update or install stock MIUI and call it day.

Oh, you mean a nightly update of LOS?
Maybe the MIUI update contained a bootloader update and the new builds of LOS were built to work with the new bootloader?

Interesting I encountered the same problem. Lineage Cannont update because 8.8.30 stock ROM Miui is required.

Simply download latest available miui firmware. Via TWRP install it and then immediately install latest LineageOS.

Here is the link to the new MIUI
