Going from Nougat (rooted) back to CM13?

Is there anything in particular I need to know regarding flashing from a stock rooted Nougat to the latest CM13 nightly? Or just the standard backup, factory reset in TWRP, install CM and open gapps, and reboot?

Just the usual flash routine. You'll need to flash the appropriate vendor too.

Thanks. I actually went ahead and did the usual flash routine but didn't flash the older vendor... Upon booting it just sat at the Google logo (the text, not the boot animation) for 10+ minutes so I quit and reverted to my Nougat backup. Did it stall upon booting because I didn't flash vendor?

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.

changed to 3.1.1-0 and did everything you said, still have boot loop...
when flashing this RR i still get this, not sure if it's a problem but thought I would just let you know
"mount: failed to mount /dev/block/bootdevice/by-name
/modem at /firmware: Device or resource busy"

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

I tried crDroidAndroid-7.1.2-20171119-clark-v3.8.3.zip and it still boot loops :\ I also already tried LineageOS and AICP before we started talking
I went back to my backup and it put me in a bootloop which never happened before but changing cache back to ext4 instead of f2fs fixed it..

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.

so should I just straight up flash the nougat image via fastboot from your thread here? https://forum.xda-developers.com/moto-x-style/general/xt1575-moto-x-pure-edition-factory-t3704142
i dont need to go back to mm stock or something first? I don't really have much knowledge about this.

Correct... And verify everything is working properly before you flash TWRP, root, or take any OTA update.

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 tried out AICP, AOKP, and RR. All latest versions and they worked but for some reason my data doesn't work on any of those customs.
guess my happiness was short lol. Considering just staying stock now

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..

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.

Actually when the phone arrived i've just unlocked the bootloader and installed a custom rom....what's the purpose of this?

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!

Going from xXx NoLimits 12.1 to OOS 9.0.4

Hello all,
I have been having issues with upgrading from NoLimits 12.1 to 9.0.4. I know I have to go to 5.1.7 to jump to 9.0.4, but when I try to go back to stock 5.1.4, it keeps rebooting into recovery whenever the phone is booted up. It would get to the NoLimits splash screen and then reboot into recovery.
This is what I try:
https://forum.xda-developers.com/showpost.php?p=78687697&postcount=23
Any combination has the same result (It would get to the NoLimits splash screen and then reboot into recovery). I am at wit's end. No idea what to try anymore. Can anyone help please?
EDIT: I did try NoLimits to 5.1.5/5.1.6/5.1.7 but same as above.

Maybe you did not wipe system, data, cache before flashing 5.1.4, as clean installation so you have the splash screen left?!
Maybe you can describe your personal steps and files you flashed as detailed as possible.

Sorry, I wiped everything and followed what it said in the thread I linked. However, wiping system before flashing the rom just gave an error that no os is installed even though I flashed the 5.1.4 rom afterwards.
Recovery is TWRP 3.2.3-x blu_spark V9.85.

Also, the issue isn't the splash screen but the fact it reboots into recovery after flashing any rom that is not xXx NoLimits.

Even jumping from xXx NoLimits to 9.0.0 after removing the compatibility.zip from the ROM file results in the phone getting to the splash screen and then rebooting into recovery. I don't understand what could be causing this issue. I can't think of anything that would cause such an issue.
EDIT: When I wipe vendor, I get stuck on a black screen after the splash screen.

I solved it. I had to flash blu_spark_r161-oos-pie_op5-op5t_2b876d534.zip after everything.

Flash a Custom Rom in 2020?

For the past 24+ hours I've been trying to flash a few custom roms on my UNLOCKED BOOTLOADER OP6T, but the phone TURNS OFF a few seconds after the boot sequence/animation.
I've read about the A/B slots and tried the Roms' flashing instructions, along with a few suggestions from others, but I cannot get any Custom Rom on my phone...
Here are the steps I've taken to flash (a few times I tried different things that I'll put in parenthesis). Is there anything ya'll see that I'm doing wrong?:
Starting from OOS 10.3.2 Fastboot Recovery and all required files on an OTG USB Drive

My Guide for Lineage, however it will work for most AOSP based ROMs.
I assume you arent manually switching slots. Don't, there is no need, in fact dont worry about it. Slots will switch automatically after flashing a ROM when you reboot recovery. There is no cache partition, stop wiping this, its not doing anything. There are two slots, but only one data partition that is shared, there isnt a reason to keep wiping it.
On most instructions adding or removing steps will make things not work. Unfortunately for this device there is a lot of out dated information and information that just doesnt work. My guide has been tested with 10.3.3, and the latest version of LOS, however if you have a T-Mobile 6T you are on your own. (I have a regular 6T)

Thanks for the comment! I just followed your guide, but still seeing the boot animation for a few seconds, then the phone vibrates and turns off.
For kicks, I decided to Format Data and I see the boot animation longer, all the way to the end when it's about to start Android, but then it vibrates and shuts off. Strange.
I'm thinking there is something different about my phone... It's a global, unlocked version and I've rooted/flashed hundreds of roms over the years on various devices, so all of this should be a piece of cake................. Thanks!

After the shutdown go back to twrp and extract the content of /sys/fs/pstore/* and upload the files here.

Thanks. I actually gave up and setup stock OOS again, so it took a while to get a TWRP backup, etc. etc.
So after the backup, I installed Xtended + TWRP, reboot to recovery, installed Xtended + TWRP, wiped dalvik, and reboot to system.
Boot animation shut down issue as usual.
Afterwards, I copied the pstore folder (attached zip).
Thanks!

Anything in the logs I can look for?
This is driving me crazy. I flashed MIUI just fine (because it had the .bat file that does everything for you). Essentially it's doing the same thing as flashing OOS & Rom on A/B, right?
Just tried flashing the newest Xtended Rom (May 11th), same issue. Phone vibrates and completely turns off while the boot animation is running.
