[GUIDE] How to get CM 14.1 working.

Hi,
So I have created this thread just because I can see many people creating new threads as after flashing CM 14.1, their phone doesn't boot up. So for all those who are going to flash CM 14.1 or have already flashed it and can't get it working, this thread is for you.
What you will need:
1. Rooted OnePlus X (Obviously)
2. Custom Recovery (TWRP recommended)
3. Latest CM 14.1 build
4. Arsenic Kernel or BlackReactor Kernel
So this is how you get CM 14.1 working on your OPX (make sure your battery is above 80% just to be sure that nothing will go wrong considering battery's point of view)
Make sure you have backed up everything before performing the following steps as the process will wipe your data completely. (I would recommend to take a Titanium backup of all user apps and then taking a nandroid backup of system and data)
1. Download the required files and place them in your SD Card or internal storage
2. Reboot your device into recovery
3. Go to wipe, and swipe to factory reset (Note! This will completely wipe all the data from your device including app data and SMS! This won't wipe the contacts but just to be safe, have a backup of all your contacts)
4. Go to Wipe again, and go to Advanced wipe, select the following partitions - System, Cache, Dalvik cache. Swipe to wipe (Note! Make sure you have a backup of the System as this will wipe the Operating System from your phone!) Although this step isn't necessary, I like to do it.
5. Go to install, and direct to the location where you have saved the CM 14.1 zip file and the kernel. Select the files, and swipe to flash.
6. If you want anything else in your system, direct to that location, select the zip file, and swipe to flash. (Note! You need not flash the SuperSU zip file as CM offers Root access in developer options)
7. Reboot your system and wait for it to boot.
Viola! Your device is now running official CM 14.1 nightly.
Hope this helps! ?
Downloads:
1. Latest CyanogenMod nightly - found here https://download.cyanogenmod.org/?device=onyx
You can have any version of the nightly as long as it is CM 14.1

Good Evening, @aamodjoshi23 THX a Lot. You are my Hero. Finally it works.
greetings

If you're facing some Error 7 while trying to flash cm 14.1, you can try updating the bootloader following this
http://forum.xda-developers.com/showpost.php?p=69267239&postcount=2560
I used the Oxygen OS 3.13 full ROM as recommended, edited updater-script (following those instructions)
Immediately after flashing the OOS 3.13 rom, you don't have to reboot.
I immediately flashed twrp 3.0.3 original from https://dl.twrp.me/onyx/
I then rebooted into twrp 3.0.3 (using the reboot button in twrp, then bootloader)
Then I installed (in this order):
cm 14.1 (https://download.cyanogenmod.org/?device=onyx)
arsenic kernel (as recommended above)
opengapps
Not sure if this step is necessary, but I wanted to let twrp patch the rom to not overwrite twrp so I rebooted into twrp again (using reboot --> bootloader in twrp)
Then I used reboot --> system
First boot took a while, but now I have nougat!!

Yes, as when you flash the CM 14.1 build, the kernel that is provided with the build is also flashed, and that is not supported. So you need to flash it every time you flash a CM 14.1 build, but if you want to flash any other build, something like CM 13.0, then you need not as the kernels provided in those are supported.

Hi,
I have a very specific problem. I rooted my Oneplus x few months back and everything was fine. I use to get update notifications and after downloading it use to update automatically. But since last 2 months i download the update files but it takes me to recovery and then i cant find the zip file to flash/install. (i also started using external sd card two months back, but not sure if it has to do anything with this). I tried searching a solution on web - tried checking 'system' under Mount tab, installed an app for auto update and some more but no use. I even connected my phone in recovery mode to laptop and copied the zip file to internal memory but while flashing it gave error.
Now i am not sure what the problem is. Do i need to update my recovery or something else. Pls help.

In October oneplus updated to 6.0.1 officially i.e OOS 3 it brings new bootloader to the device as you are using old recovery you can't flash new update..so you need to upgrade to latest bootloader by following thread available in general section or you can flash stock recovery and upgrade to latest OOS and flash whatever you want to flash..I recommend you to see how to upgrade bootloader in general section if you are planning to flash custom ROMs or if want to flash latest OOS then simply flash stock recovery and upgrade. onece you updated to OOS 3 after that you can flash new official twrp 3.0.3.0 from its official page.
Edit: for old bootloader you need stock 5.1.1 recovery..which is not available in official oneplus download page..so just follow below link

I made a blunder. I read somewhere to upgrade TWRP to 3.0.3 and after doing that now i just can't access the recovery mode. When i try to boot in recovery mode the screen gets stuck with One+ logo. Then I even tried to Factory reset and the phone rebooted to the same screen stuck with logo. I longed pressed the power button and it got switched off and then again turned it on. It started and is working fine but I cant factory set it, nor cant I access recovery to flash anything.

This is because you flashed wrong recovery twrp 3.0.3 is for new bootloader and you are on old bootloader..that's why it all happened..so you just need to flash old recovery..then follow given link to upgrade bootloader and recovery.

I've got a good news and bad news for you.
The bad news is, no one has the older 2.8.x TWRP image files and there are no threads that have the download links for the older version of TWRP. So you're stuck and you have lost your recovery. You have lost everything... Having no recovery means you can't do a lot of things like factory reset, any wipe of a partition, you won't be able to update your system, you won't be able to flash zip files to enhance your experience and many more... I'm sorry my friend...
The good news is, I've got you covered. I had saved the older TWRP so that if anyone one day would need that recovery image, I would be able to help them.
Download the older TWRP from here : https://drive.google.com/file/d/0B2Ms-zaNd3SiTmpxX0UtYUV2R1k/view?usp=drivesdk
Flash it. You should get back your recovery.

By stuck on boot, I didn't know you meant that it showed only the OnePlus logo and not even powered by Android.
In that case, follow this guide to update your bootloader :

Cant flash any ROM

So here is my problem i can't flash any custom rom i tried twrp cwm philz edition and the problem is the same i get stuck at* patching system image unconditionally at the very beginning of the blue line i tried with resurrection remix, slimrom, and other ROMs and when trying MIUI 8 i get an error couldn't mount system rw
Itried with adb sideload get stucked at 45%.
I e2fsck -y /dev/block/mmcblk0p23 wich is my system partition and fixed so many error but the problem stay the same ... i can flash a recovery or a kernel with no problem with TWRP the problem as i think when dealing with the system partition .. so im stuck with a stock rom that i flashed with odin btw who works great .. so is it my system partition messed up or the gpt table isnt right or is there a way to flash custom rom using odin

It could actually be the permissions. Other problem could be the recovery.

hi i know it's been a while since, but have you found a solution? I am getting exactly the same problem and tried everything possible. at the stage ready to sell it off ebay and upgrade if this doesn't work.

I had same problem with galaxy note 3 sprint variant and twrp 2.8.7.0 helped
If you are not getting twrp 2.8.7.0 try two or three lower versions
Don't use the latest twrp it won't work

1. Try to put custom rom to external storage microSD card or USB otg
2. If not helped 1. solution try older version TWRP 2.5.xx
This 2 solution help for me sometimes

You need to flash the latest TWRP.

Thanks, and I was on the latest already at the time of posting. Will try the two suggestions with getting the older versions of TWRP 2.8.7.0. Interestingly enough the CWM has done the same thing, as well as TWRP's sideload.
Will post back later.

tried all the possible versions of twrp, sideload, cwm, different roms, fixing permissions and formatting the partitions...no luck, still gets stuck at 45%. I guess it is time to give up and get myself a new xmas present.

Boot Partition Hidden in TWRP

My rooted Axon 7 (A2017U) does not show the boot partition in TWRP when backing up or restoring a backup that previously showed the boot partition. Here is what I did prior to the problem:
1. Manually updated stock rom to B32 using DrakenFX procedures, which includes flashing bootstack. (I made a backup after the upgrade of boot, data, and system - as usual.)
2. When I restored AICP nandroid, boot was shown along with data and system. Phone operated normally, but would not flash OTA upgrade - error 7. (Attempted to flash a previous version that I had flashed before with the same error 7.)
3. Rather than unzipping the rom and deleting the asserts line, I flashed the universal boot image from LineageOS and was able to OTA without issue, but when I ran the TWRP backup, boot did not show and only system and data backed up.
4. Restored the stock nandroid, boot did not show.
My phone is operating normally, but I find it disconcerting to have made an unintended change and would appreciate any help in correcting my error.
Thanks in advance.

No, still waiting for assistance.

Reflash TWRP. I had partitions missing and there was a weird version of TWRP installed for unknown reasons. Reflashing the latest TWRP fixed my problem.

That worked. Thank you very much. Weird how that happened.

Just as a matter of interest, I just did a clean install of AICP, which required installation of universal bootstack, and found that TWRP version had been replaced with an old version that did not show boot partition when doing nandroid. Reflashed current build image and boot file was visible.

Keep the latest .img on TWRP, and when you flash the universal bootstack, flash the TWRP .img after. I've asked over at the LOS thread if they could update the TWRP version on the bootstack and nobody answered lol

Should we use the one from twrps official website? I'm having the same issue but I can't remember changing my recovery.

You don't change your recovery, the universal bootstack zip does
It's the same whether you use the zip from TWRP's official website or raystef66's download center really

Stuck in bootloop trying to flash 7.1 custom rom

My phone is android 6.0 and I've been using "TruPureXMM 2.9" ever since it first came out. I have a February 1, 2016 android security patch level and my system version is 24.11.18 clark_retus.retus.en.US retus
I had an older version of twrp so I just updated it to the latest one before attempting this ofc...
I tried flashing the latest RR and AICP and both give me boot loops and I always get this one problem where it says
"mount: failed to mount /dev/block/bootdevice/by-name
/modem at /firmware: Device or resource busy"
I'm not sure if this has anything to do with the bootloop though...
Going to recovery after seeing the bootloop I always get the "keep system read only?" prompt where i swipe to allow modification but i usually just restore back to my backup from there... i dont think allowing it and trying to boot again will get rid of the bootloop...
I followed the process of first doing a full wipe with twrp > flash rom > flash gapps > restart system
no idea what i'm doing wrong..

1st - you need twrp 3.x+,
2nd - full wipe - format data, adv.wipe - all without micro sd.
3rd - flash rom, flash gapps(opengapps.org, ≤mini, arm64, 7.1)
Last Rr is for Nougat modem - you are on MM modem.
Flash RR 21.11.2017.

The first 3 steps I've already done that since the beginning
Where can i get the nougat modem/is it possible to update to it? I guess that's the reason every single 7.1 custom rom I tried in the android development section gave me boot loops...
And could you link the 21.11.2017 version of RR? I'm looking at the download links for RR and I dont see one with that exact date
edit-just saw your edit

Custom roms for MM modem works better.

I fully wiped using TWRP, checked everything I possibly could except my micro SD card and I flashed RR-N-v5.8.5-20171121-clark-Final.zip then gapps arm64, 7.1 nano and it's still giving me boot loops. I'm using TWRP 3.2.1-0
im gonna try using gapps arm64 7.1 mini really quick since you said I should use that one and see if it boot loops... - Edit guess I was too optimistic thinking this would fix it

Bugs probably after flashing december RR.
Change twrp to 3.1.x, reboot twrp, change all partitions to ext4 - adv wipes - One by one - cache, system, data, reboot twrp.
Change back to f2fs - only cache & data, wipe all, flash what I wrote.

It doesn`t matter.
Try another custom - LOS f.e.
If bootloop still will be - you should flash full stock.

A little late to chime in and this does not help with your current situation, but here's a little advice. I flash a lot of ROMs (how else am I going to test builds right?). This error happens all the time, BUT if you flash a ROM twice it should not show on the 2nd flash.
So flash order goes:
Wipe/Factory reset
Format data x3 (yes I format my data 3 times for every ROM)
Reboot
Wipe/Factory reset
ROM
ROM again
GAPPS
Wipe caches
Reboot
Do the Initial setup
Reboot before use
OPTIONAL Kernel (if its not already build in)
OPTIONAL Magisk (I never flash Magisk on a clean build but heck I'm expecting a NON boot most of the time anyways)

At this point I would flash the stock Nougat image via fastboot to get the device operational again... Then look at TWRP, root, or custom ROM.

Boot TWRP (don't flash it) and make a full back, and I would recommend not talking any OTAs either.
Then knock yourself out... You can always get back to this state if things go badly.

I'm not sure for others but RR - only 5.8.5-04.12 works with N modem.
Did you check/set access points properly?
All customs for N modem(I think) have problems with notification sound, so you can stay at stock.

I'm using t-mobile and I've checked the access points, clicking on the one im using and hitting save doesn't fix it. Always getting a notification telling me to sign in to network. Not sure what else I can do. I'll give it a day since I had this kind of problem before when I switched sim cards and data didn't work until the next day
Edit - just went back to stock and my data doesn't work now either... just going to stay at RR now and hope my data fixes itself because my access point settings for tmobile should be correct since I looked it up on the official website..

Can't install any custom ROM. But why?

I wanted to upload a new rom to my phone (pine, 16GB), but it will never boot. Always after rebooting, TWRP will be loaded again. I'm tried multiple ROMs (LineageOS, DotOS, MokeeOS ), but the problem occurs for all rom. TWRP says, flash succed for every one system, but not booting after reboot.
I'm used twrp-3.5.0_9-20210101-pine-arm64 version. Only I can do flash a stock rom using MiFlash, but no custom rom via TWRP.
Mi device is correctly unlocked via Official Unlock Tool app.
Can you tell me why?
Thanks

Maybe try another twrp version or another completely like OrangeFox can't really tell you why i don't have as much knowledge in why or how it works but i have tried a lot on mine so this should be ur first troubleshooting step from my point of view also have you flashed the ROMs with their instructions some say the sequence you should format or wipe ur data etc...

Working for now,
The problem was that I didn't choose to Format data
