[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! ?

1. Latest CyanogenMod nightly - found here https://download.cyanogenmod.org/?device=onyx

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 :

Stuck in bootloop in all LOS and OOS based roms

Hi guys, been using my rooted but otherwise stock OOS rom with TWRP and Magisk for the past few weeks. Today I decided to take the plunge and try either the Lineage OS or Resurrection Remix roms.
I'm using the latest OFFICIAL TWRP.
So I decrypted following the instructions to flash "no-verity-opt-encrypt-5.1.zip", then format data. All went well, so I then sent over the ROMS I wanted to try out. I started with the official ResurrectionRemix. Bootloop. Then the unofficial LineageOS. Bootloop.
Ok, well I guess I'm not gonna get to use any of the cool new OS's for awhile. I'll install the full stock firmware zip so I can have a working phone again. Bootloop.
Now when I say bootloop, the phone is booting to the BootAnimation and just repeating it. It shows the proper boot animation for whatever zip I have installed (resurrection/LOS/OOS), but it stays on there for up to 20 minutes before I have to hard reboot to the recovery again.
I decided to install the stock recovery trying a few methods. I first tried the ALL-IN-ONE tool. It said it flashed the recovery fine, so I booted to the recovery and after staying on a black screen for too long, the language options came up and I sighed a breath of relief. But before I could select English with the volume buttons, it rebooted by itself. It did this again when I manually entered recovery. So I figured maybe the tool flashed the wrong version, so I googled stock recovery for OnePlus 5, I found a few random links for stock recoveries for the OP5 and flashed them, but they more or less do the same thing or not boot at all.
I've tried changing the filesystem for both Data and System using any combinations of EXT4 and F2FS. Everything results in boot animation bootloops.
I have been flashing Roms since the Samsung Galaxy S3 and every phone since and never had any problems.
Currently when trying to install the stock Full OOS official zip with TWRP, the phone won't even go to the boot animation, it only goes to a black screen with the top LED in a light blue color.
I have also tried every version of TWRP there is for the OnePlus 5. Unofficial, Official, 3.1.1-0 and 3.1.1-1.
So I guess my question is....What filesystem is each partition supposed to be on and for which OS?
Lineage based:
System: ?
Data: ?
OOS Based:
System: ?
Data: ?
And any ideas on getting my phone running again?
And anyone have an official confirmed working version of the stock recovery? The one from ALL-IN-ONE TOOL doesn't work for me. It loads the language selection, then the screen goes black with a light blue LED on the top of the phone.
Actually I'm getting that on some roms instead of the bootanimation, like FreedomOOS. What does it mean when you have a black screen and a white LED?

Man, I really thought I was getting somewhere. If I boot into TWRP, change the Data partition to "F2FS", then flash the stock recovery, the stock recovery will boot, however, when inside the stock recovery and I try to flash the stock zip, it says "Flashing, don't turn off your device" for about 5 seconds and then goes back to the list of roms on the SD card, not having flashed anything at all.

Ok, I have the official stock recovery from the OnePlus site, but still can't use it. Here is was happens depending on how I left it with TWRP:
System: F2FS
DATA: F2FS
- Stock recovery will load after some time, freeze, then the screen goes black with white LED on top.
System: EXT4
DATA: F2FS
- Stock recovery loads fine, I can go through the settings and install from SD card, but when I do it says "Flashing, don't turn off your device" for about 5 seconds and then goes back to the list of roms on the SD card, not having flashed anything at all.
System: EXT4
DATA: F2FS
- If I try to flash stock rom through TWRP, it just boot loops on the animation forever.

I have now also tried flashing the stock boot.img, but no difference.

I have 2 things you can try!
First, replace the bootloader with stock and do a factory reset:
1. flash the stock recovery over
2. then in fastboot mode enter, fastboot oem lock (This forces the phone to wipe cache and data, and also do a complete reset)
Did it work? if yes YAY if not go to Second!
Second if your system.img is ****ed up you have to replace it!
Download the newest version of the stock rom from oneplus link here
Unpack it
research how to use an extractor to convert the system.new.dat to system.img
once thats completed enter fastboot mode and flash the new system.img over with Fastboot flash system system.img
now go into recovery and do a factory reset and wipe cache, and dalvik
Please reply back wether or not this work

"Ihave 2 things you can try! First, replace the bootloader with stock and do a factory reset..."
Is the bootloader simply the boot.img?

After doing the first thing, it simply says that the device is corrupt and will not boot. But it is locked again.
But I will have to unlock it again to do any further flashing.

Hmm, I think I may have gotten it. After unlocking again, flashing the stock recovery and boot.img, then locking again and wiping in the stock recovery, I have finally booted into the stock rom.
I still have no idea what went wrong, and I really want to know, so that in the future I can flash other Roms, like LineageOS.
I mean, I followed the steps exactly.

If it says the device is corrupt it simply means you got something else besides stock rom.
So now unlock it and try the system.img instead

It was because I still had TWRP with the stock rom.
I got it working though, thanks for your help.
Do you have any idea on what might have went wrong when trying to flash the lineageOS based roms and why it got messed up so royally?

Great to hear you fixed it ^_^
Probably some minor bug, if you wanna try installing lineageos again use the 3.1.1 TWRP build that supports backups and do a full backup so you don't have to go thru all this again
---------- Post added at 12:17 AM ---------- Previous post was at 12:13 AM ----------
Not really just try again but remember to use TWRP 3.1.1, as 3.1.0 don't support backup and probably have been part of your problem
If your trying again and gets it successfully installed could you do me a favor and test if Drivedroid works on it? And pm me the result, I'm looking for a rom where Drivedroid will work... Haven't found one so far

You know, I did do a backup with the OFFICIAL TWRP, but it also resulted in a bootloop. I made the backup after decrypting, so I don't know why it bootlopped.

https://forum.xda-developers.com/oneplus-5/development/rom-unified-lineageos-7-1-2-t3635483
Is this the one you tried installing?

I tried like every ROM at one point yesterday, but I think I started with
https://forum.xda-developers.com/oneplus-5/development/rom-resurrection-remix-n-7-1-2-t3636578

Did you remember Gapps?
Also in some cases its better not to root before you have the custom rom running, you usually only need a custom bootloader like TWRP

Yeah, I tried with Gapps, and I never rooted before first trying to boot.

As of yesterday Ressurrection remix, released the first official stable build so try again your should'nt have any problems if you follow the guide 100%

Ever find a solution? I'm stuck here now. Can't get any ROM to boot up, they all get stuck on the boot animation

Bump. I am also stuck in this state

Why can't i use any rome except OmniROM? The Phone does not boot at all.

Hi there folks!
Sorry if i open a thread, probably you've discussed somewhere before about this problem that i'm experiencing.
My OnePlus 5 basically works only with omniROM, it doesn't boot at all when i try to install another one.
I tried with this:
https://forum.xda-developers.com/oneplus-6/development/rom-aospextended-rom-v5-7-t3825642
and this one:
https://forum.xda-developers.com/oneplus-5/development/rom-crdroid-android-5-0-t3836886
I followed every step (About CRAndroid), radio firmware 5.1.5 + TWRP 3.2.3 + Gapps + Magisk 17.1 and No Verity v3 (First try without noverity, second using it)
and i followed also every step neeeded in AOSPExtended rom.
When i try to boot the phone, after the OnePlus logo, nothing happens. The phone reboots in recovery mode, that's it.
If i repeat the same steps with OmniROM it works all fine, except Magisk. If i flash Magisk on the Omni it doesn't boot, if i flash SU it works.
Could it be something related to the encryption/Decription of the device?
When i go into TWRP it doesn't ask me for a pattern or a code. It should be decrypted, right? (i'm a bit confused about that).
I purchased the phone on Gearbest, could it be a particular version of the phone that doesn't allow me to work properly with roms?
Help

did you tried old stock ROMs, 4.* versions ? then 5.0.0 and then the others

Sometimes the partitions need to be wiped. Try a fastboot format userdata; fastboot format system.

You....you're a good guy.
I did the command you said, then i booted into TWRP, flashed AospExtended, Gapps Pico and Magisk 17.1 - after reboot it has been stuck @ 1+ logo, then it rebooted again (as always when it doesn't work) and i said "ok here we go again in the TWRP-loop" and INSTEAD it booted rom! Yes!

TWRP install impossible, phone doesn't make it past fastboot splash screen

Hey guys,
I just oem unlocked my new 6T and have access to the bootloader. As I try to install TWRP with
HTML:
fastboot boot imagename.img
my computer says that it pushes the image just fine, but my phone restarts and then never makes it past the fastboot splash screen instead of loading up TWRP.
I was following the fajita (6T) instructions from the lineage OS website.
The first time I did it it worked, but following the instructions on installing lineage and telling me to wipe and format data, both the recovery seems to be gone and i cannot fastboot boot into TWRP.
Can you help?

Seems the same with what i experienced. Have you tried installing a fastboot rom? I had my oneplus 6t bootlooped into fastboot mode even if i try to turn it off, it just boots back automatically to fastboot mode. Last resort was to flash a fastboot rom. That worked for me.

I tried 3.3.1.1. and 3.2.3.0.

What you are describing, I'm going to assume you are trying to install Lineage 17. You can't install TWRP if you are going Android 10, at least that's the conclusion I've come to at this point in time. It will fail to boot or end up in crash dump mode every time you try and enter recovery if you are on a custom ROM. If you are on Android 9, it's not an issue. I believe it's OK stock as well, but I don't know haven't tried, haven't been stock in a long time.
For LOS 17, only boot the TWRP image, never boot to recovery, never run the TWRP installer. You will likely still have to format data.
I have a post here, from when I had a similar issue. (instructions)
You'll notice the OmniRom instructions don't mention installing TWRP, only booting it.
Once I was in your spot, I always went back to stock using the fastboot ROM, installed TWRP, updated (still using TWRP), then started over with my install.

Well no, i was actually trying to install Lineage 16, which is Android 9 I believe.
The problem for me is that I do not get to the point where TWRP opens after "fastboot boot"ing it. So I understand, I should use a fastboot stock ROM? Is there such a thing? Where would I find it? Or would it be an OnePlus Oxygen ROM that I can fastboot?

Quickest way to start over:
To get back straight your gonna need to access a Windows PC, and run the MSM tool. Make sure you install both OnePlus and Qualcomm drivers. ( Don't wait for Windows, just pre install the drivers) here are some links. Not my work. Please be sure to thank the developers for creating and hosting these tools ?

Were you on Android 10 before (OOS)? That will do that. LOS 16 is Android 9 and should have no problems installing TWRP or booting to it.. For LOS 16 I'd go back to 9.0.17, then install LOS 6T.
I posted these LOS install instructions a long time ago for another user.
Remember the MSM Tool will relock your bootloader so if something goes wrong the MSM Tool is your only choice. That is why it is always the last thing I resort to.
Thread to get Fastboot stock Roms if you want to try that route first.

Hey guys,
thank you so much for all your help. I've managed to use mauronofrios workaround here on xda to put my phone in a 9.0.17 state again (no idea what i had originally), and this way i could fastboot the twrp image again. so that worked fine, but so far flashing lineage hasnt worked, for whatever reason it seems to boot into a lineageos kind of recovery only (which i didnt even know existed).
So i guess in terms of this thread the problem is solved. Thank you again!

Did you see my Lineage install instructions above? LOS installs its on Recovery when you flash the ROM. When om Android 9, boot TWRP, flash the TWRP installer, reboot to Recovery, install LOS 16, flash the TWRP installer again (replaces the LOS recovery that was installed), reboot to Recovery, install gapps / magisk if desired, reboot.
Read my instructions post though, the first time install is different, as you need LOS on both slots. Updating is different as well, its much easier.
It should go smoothly.

Do I need to be on Android 9 Stock when I start that process? What I did was boot into TWRP, flash TWRP installer, reboot into recovery, then format and wipe ALL partitions (except USB), then reboot into recovery again and then flash LOS, flash TWRP, reboot into recovery, flash LOS, flash TWRP, reboot system. Still no luck...

Wiping, Dalvik / ART, System, and Vendor is generally a bad idea. You can do them in certain situations, this isn't one of those situations you should be wiping those though. Factory reset, means the slider on the main page of the wipe screen that says swipe to factory reset, format data is the button that says format data. Don't do anything extra. If you did, yeah I would go back to 9.0.17 using the fastboot rom again, that will put everything back on both slots.

like OhioYJ stated, don't use advanced wipe. re-run the msm tool. Then follow his instuctions. You shouldn't need to preform any manual data wiping. The process of flashing will do everything required. looks like you're almost there

Thanks guys. I will try it out and let you know.
Edit: So I finally managed to properly install LOS - OhioYJ, your instructions worked! I installed 9.0.17 and went from there without wiping any additional partitions.
One questions remains: in your instructions you mention that after installing LOS once, you can update LOS as normal and you mention doing it via the recovery with flashing TWRP or GAPPS later again. Is it possible to do the update via the normal update function of LOS as well? Or will that overwrite TWRP?
You guys are awesome. Thank you so much for your help!

I seem to be stuck on the fastboot screen as well. Being on a MAC, anytime i try to do something in fastboot it goes straight back to the fastboot screen. I Thought I was on Android 10.0 trying to install recovery for that lead to bootloop of fastboot, tried using the Pie recovery and same thing. I am open to suggestions.
Thanks.

What you are describing, I'm going to assume you are trying to install Lineage 17. You can't install TWRP if you are going Android 10, at least that's the conclusion I've come to at this point in time. It will fail to boot or end up in crash dump mode every time you try and enter recovery if you are on a custom ROM. If you are on Android 9, it's not an issue. I believe it's OK stock as well, but I don't know haven't tried, haven't been stock in a long time.
For LOS 17, only boot the TWRP image, never boot to recovery, never run the TWRP installer. You will likely still have to format data.
I have a post here, from when I had a similar issue. (instructions)
You'll notice the OmniRom instructions don't mention installing TWRP, only booting it.
Once I was in your spot, I always went back to stock using the fastboot ROM, installed TWRP, updated (still using TWRP), then started over with my install.

Twrp is working fine with Android 10, using mauronofrio version and magisk 20.2

Yeah it starting to seem like it maybe isolated to Lineage. You cant install TWRP with LOS 17. Someone else mentioned in the Omni thread that it worked. This thread is about Lineage, but that should be clarified, or clearer.

SM-P580 custom rom boot animation loop

I have installed custom ROMs on several other tablets but the Samsung Tab A has me stumped.
1) started with the most recent Samsung Rom from SamMobile. Used ODEN, skipped all setup steps to the end. opened Developer Mode and set OEM unlock to YES.
2) PWR+VolUp+Hm to stock recovery, Factory reset.
3) Pwr+VolDn+Hm to download mode. Used ODIN to flash TWRP 3.3.1. Rebooted directly back into recovery not system which was TWRP as expected.
4) Rebooted back to download mode and used ODIN to flash Stock ROM again, again no setups and OEM Unlock Yes
5) Went into Download mode. Reflashed TWRP. Rebooted straight into TWRP again
6) Reformatted Data drive YES and validated drive > 0
7) Flashed Magisk with TWRP
8) Reboot into system. Stock ROM works perfectly and Magisk is working fine.
9) Reboot back into recovery and wiped data and cache
10) Flashed 3 different custom roms (1 after following all the steps above) and I cannot get any of them to progress beyond the animation bootloop.
I have read just about all of the references and others have success following a similar approach.
I am probably missing one small step. Please let me know of any ideas.
Thanks as I really want to move up to a Pie Rom

Ignore - it looks like all custom roms are for the t580 not p580. sorry.

Have you had any luck finding a solution to this?
I am also looking for a working custom ROM for the Tab
