Why,in custom ROMs section on 6t forum,every one of custom rom developer in his OP states DIFFERENT "Flashing instructions"?
Not a single rom dev,in his OP have same flashing instructions as some other dev! As I read more,it looks like half of them are wrong instructions,or that they don't have this device,or they don't know.
- flashing on both slots a&b?
flash OOS rom,them twrp.zip,reboot to TWRP (to any of slots),and internal will be encrypted and unreadable.Theres no way to flash on both slots in one take in TWRP or in two takes in row(with in TWRP,reboot to TWRP different slot).There's need for at least one full boot to Operating System,then back to TWRP,and internal will be visible and decrypt ed.
Many custom ROMs need OOS on both slots to be able to make them run,but this looks like nonsense to me.
- changing slots in TWRP?
let's say you flash magisk while in slot A,go to "reboot" and change slot to B, but dont reboot to TWRP.Now flash magisk.it will flash on same slot as first time,there was no slot changing.
- delete wipe "system" in TWRP,or worse "factory reset"?
it's mistake that costs me a lot of time,Ill never do it again.As all custom ROMs now have script that wipes all unnecessary files,there's no need to wipe system and screw your phone for few hours until you fix it.For me,a big No No.
best way of flashing custom os over OOS?
for me,I go into TWRP,flash custom rom,flash TWRP zip,then I reboot into TWRP and flash gapps and magisk.if internal is crypted and I can't flash gapps and magisk,I do a boot into rom,and back to TWRP to finish my flashing.wiola,it boots and works,clean rom and all is fine.
Flash back to OOS?I just go into TWRP,flash OOS ,flash twrp.zip,reboot to twrp and flash magisk.if internal is crypted,I boot into OOS,them back to TWRP,and flash everything else what I need(like magisk and kernel)
a/b devices are nothing new,but it looks to me Like on 6t is all overcomplicated.
So,tell me how you guys do it and what are yours ways of doing it right?

I agree with you!!! This is a mess
even though I have flashed thousands of roms over the years, since I got rid of my Nexus 6, I havent had a phone that I could flash roms on, so, after dumping my Note 8 for this great phone, I was very hesitant to flash a custom rom, for all the reasons you have mentioned..
So, my question is, can you flash ANY of these custom roms by using the clear method that you mentioned in the OP?
If on one of the beta releases, is the procedure the same as I am showing below, or, do you always have to first return to stock OOS?
In my years of flashing dozens of phones, you never had to go back to "stock" if you wiped everything before flashing, but, it seems like on several of these roms, you are instructed to first return to "stock", THEN flash the new custom rom...
Plus, some roms say to wipe everything before you flash, and others say not to wipe system, or not to wipe data...
Unless I am nuts, I always thought that you wipe everything before converting to a totally new rom, but, maybe I am wrong here too..
"for me,I go into TWRP,flash custom rom,flash TWRP zip,then I reboot into TWRP and flash gapps and magisk.if internal is crypted and I can't flash gapps and magisk,I do a boot into rom,and back to TWRP to finish my flashing.wiola,it boots and works,clean rom and all is fine."
These instructions seem pretty clear and concise, hopefully, they are correct, and we can just use this exact method and be done with it!
No mention of wiping in your directions...what do YOU wipe before flashing a new custom rom?
Hopefully, this gets cleared up once and for all, and we can ask the MODS to make a sticky of the ACTUAL CORRECT INSTRUCTIONS>>
thanks

-if on custom rom,probably it's good to first go to stock OOS and then to another custom rom.but this is also strange to me,as I don't understand what are benefits of this.i also read this,Google heh.i tried going from AOSCP to PixelEcpirince without flashing OOS in-between process,all was fine.
-I haven't been on Beta OOS yet,only stable.But that thing bout "before flashing custom rom,flash stable OOS even if your on Beta OOS" is also a big question to me.they are practically the same,both are latest OOS,one maybe more stable them other,but this also can be discussed hehe
-i don't wipe anything!! when my custom rom boots,I go into it's settings, without setting my Google account and other stuff, and I do "factory reset"( not in TWRP,in custom rom's settings!).Phone reboots,and all is fine,clean beginning,TWRP works,root works.About unwantedFolders in internal storage,I delete them manualy.
Only thing in my experience to wipe in TWRP is DATA,but this is also questionable,as I run into problems also doing data wipe I TWRP.
Now ROMs(maybe only for a/b devices) have scripts that wipe previous System during flashing new rom,so we don't have to do a Clean Flash anymore.
I'm also confused,more I read,less I understand ?
I like the idea of wiping via factory reset, once the rom boots, but, if it does NOT boot, then you wouldnt be able to do it that way..
I guess flashing an OOS based rom over an OOS based rom would always allow you to boot, if done right..
But, roms like RR, Carbon, AICP, and a couple others that have shown up here recently were never really OOS based roms, but AOSP based, at least I thought so..
the more I think about this, the more confusing it seems to get..

This is from the pixel 2 xl forum another a/b device
First time installing Pixel Dust ROM, or coming from another ROM:
As mentioned above, you are required to flash stock ROM before installing this custom ROM.
1. Flashing Stock ROM:
Follow these instructions: https://developers.google.com/android/images#taimen
2. Flashing PixelDust ROM:
Reboot to twrp
Wipe Dalvik cache and Data partitions
Flash ROM
Flash twrp zip
Reboot to System and enjoy the Pixel Dust Goodness!
Flashing Magisk:
You cannot flash Magisk during the initial install. You must boot into PixelDust ROM at least once!
Reboot to Recovery
Flash Magisk-v17.x.zip
Reboot to System

You make it overcomplicated.
To flash both slots you only need to do a complete reboot to make sure the OS is not hosed.
You do that so if it is you can use the other slot. This is not necessary.
You flash in TWRP, change the slot and reboot into TWRP and flash the other slot.
It could be easier if TWRP allowed flashing on the inactive slot.
But, even if you are rooted and want to upgrade it is suggested to upgrade both slots.
I think it's just a minor pain. There are bigger problems.

it's not a minor pain if most of time that I go to flash custom rom,I lost all my 60-80gigs of internal data, cuz of failed decryption,or failed rom flash,or failed TWRP flash.There were times when I did Factory reset in TWRP,flashed OOS,flashed TWRP.zip,did reboot to recovery,and I lost recovery.I was left with bootloader (fastboot) and had to fastbooting OOS few times(which led to full wipe of internal storage).OOS wasn't even flashed,or TWRP wanst even flashed.And I just followed instructions.
this are the things that I'm talking about.Even if I follow instructions, instructions are not detailed.
now I probably know how to do it right,,but still...I learned it hard way,and still learning
thanks for your opinion and answer:good:

I understand now.
The instructions are not clear for most of this stuff and you can screw up.
If something fails to flash, there are very few reasons to ever completely wipe. Even a factory reset does not require a complete wipe of data.
I would suggest at all times keeping a boot image of the current OS you are using.
I would also suggest keeping a TWRP.img on your computer. You can always boot from a TWRP image even if it's not the one you want to install.
That will at least get decryption and the ability to flash.
I don't flash custom ROMs, because the stock one with root does what I need. Also the fingerprint sensor is not guaranteed under custom ROMs and I need that to work.
no verify opt on most after data wipe or that brands version of it, then reboot to twrp verify is still not there because twrp will say no os installed the avb changed things every phone is different depending on their security Samsung for one
Try this guide. Read the first paragraph if you have problems with decryption.
Boot twrp
Wipe dalvik and data
Flash rom+twrp
Reboot SYSTEM!
Boot back to recovery
Factory reset
Flash gapps+magisk
Reboot and done
No data loss or PC needed...
So here's some food for thought. I read somewhere that when you install a ROM zip via TWRP it actually Installs to the Inactive Slot. And when you reboot to TWRP after reflashing the Installer it Switches Slots and then you can Flash GAPPS etc. But what if someone were to flash the ROM twice ; once to each slot? Would be noice if We can use this to Multi-Boot Two ROMs at once....

I think that question was asked in one of the threads in here "can use this to Multi-Boot Two ROMs at once" and I don't think it's possible. I'm sorry I don't remember the thread it was in. You might try Google.
It's wise to do the oos in both slots which you can switch slots without rebooting fyi because when you flash a custom ROM no matter if you switch back to a it'll flash magisk and probably gapps in the inactive slot. If you try to return the custom ROM to slot a after it flashes it will say insufficient room for gapps and such. So to me it seems this makes it a clean slate so it can flash to inactive slot. Hope that clears up why they encourage the double oos flash
Everyone, I think you have almost helped me figure out how I screwed up my 6T. I made a post needing help but this thread I believe is the answer. I wanted to install lineage16 but opted for Resurrection Remix since that dev claimed the fingerprint reader worked. To make a long story short, I flashed the latest .15 OxyOS update first, switched partitions via TWRP and flashed it again, them flashed TWRP and rebooted to recovery. Flashed Remix then TWRP again and rebooted to Remix. Now I have no room for anything in storage although it's only 25% full and my file explorer cannot access any storage not can I update apps through play store or anything. I have the latest OxyOS on my OTG flash drive as well as TWRP and magisk, but every time I find a thread on hope to do an installation, it varies and I keep coming back to this storage issue. Can someone PLEASE link me out tell me where to find the correct process to now start from the beginning and get my phone back working on the OxyOS .15 stock rom? Thank you very much and I'm glad I found this thread because it finally makes sense as to how misinformation is causing many people to have issues.

You may have solved this by now, but I found that using the MSM Download Tool has enabled me to return to stock OxygenOS even after getting stuck in a boot loop. I've not been able to successfully flash RR or LineageOS however, still getting stuck in said boot loop...
I was using OOS. Switched to Lineageos. Now I'm on Havoc.
OK that's out of the way.
I installed the update today for Havoc. Went to reboot into twrp to re-root, now it's booting into the lineageos recovery. I would just use my computer to boot from twrp again, but alas I'm stuck at work
Any ideas?

Try switching slots. Chances are, you flashed havoc to the other slot
How do I do that?

In recovery. When you hit reboot, at the bottom you will see A and B. Choose the other one
I don't have that option.
Oh. So you're not on an A/B device. Gotcha. Well, you may just have to clean flash then. Since you don't have to worry about a recovery partition. Because you have a dedicated recovery partition. You can't dirty flash different ROMs over each other
Delete
I'm on a 6T. I flashed the new version of Havoc on it, went to reboot afterward to install magisk, but twrp was gone. A recovery from when I tried lineageos was on the other partition, and I'm guessing it swapped to the other partition.
Just flash the rom twice so it is on A and B. Here never had a problem on my.op6 and 6t
Hey guys
I made a post and got no replies but have been looking into it more and remember I need adb to flash the 10.3 update, I've got all the files ready but from reading I'm confused as to how to flash via adb.
I've read you need the phone in twrp while doing flashing you need to flash the other slot blah blah blah , doesn't make sense to me...
Can anyone help me out? I've seen stuff has changed since the 10 update and I'm at a loss right now..
Thanks for any help in advance

You nearly never need adb to update.... Dable in some circumstances with fastboot.
Just...update. You don't specify what OS you run now, rooted , twrp etc...
Read my thread about OOS stable in Guide News section and ask there if it's not clear

You're seriously late in versions of TWRP and Magisk. Update twrp with latest installer.
Then in twrp flash OOS, then twrp installer again
Reboot to recovery to switch slots
Flash again OOS and TWRP installer again
Reboot to twrp and flash Magisk then reboot system
If there's issues with encryption in recovery you can eventually use an OTG disk if you have one or ADB sideload
Last possibility is fastbooting oos ROM

Brilliant thanks! I've updated twrp and magisk now, had no internet so couldn't update. Do I not need to wipe the internal storage at all when flashing stock oos ontop of havoc?
And for the slot just so I know for certain;
I flash slot A with oos, twrp.
Now I reboot go to slot B, do the exact same.
Reboot again, flash new ROM , twrp/magisk.
Profit? I read you post detailing the slots, that's the part that confuses me. I'm going to have another read so I fully understand what I am actually doing instead of doing everything blind.

Anytime you go from AOSP to OOS, or back you generally have to wipe DATA. If you don't OOS will dump you off at recovery, wipe data and then it will boot generally.
As for the slots, when flashing a ROM it always flashes to the opposite slot. So if you are currently on Slot A and you flash a ROM, it will flash to Slot B. The ROM will also overwrite install it's own recovery. So you install TWRP again if you want. Then you reboot to recovery, it will automatically switch to the new slot since you installed a new ROM. Now on the slot where the new ROM is installed, we could install Magisk or Gapps, things like that if needed. If we wanted to update the original slot (A) we would install the ROM again. As well as TWRP again. Reboot to recovery again, Magisk, etc.
ROMs install to opposite slots. After a ROM installation, rebooting to recovery will switch slots for you. Most other items install to the current slot (that is why you need to reboot before install things like Magisk, Gapps, etc). Hopefully that helps clarify things? If not ask.

That does clear up things for me, I've either mis-read or not read that when on slot A you are actually flashing slot B and Visa versa.
I'll be flashing both my slots to 10.3.1 just so they're fully updated. ( A is my main)
Finally part from me, when I'm going to flash my custom ROM (havoc again) I've just got to repeat said steps but flashing havoc instead of OOS then on the last reboot, recovery and magisk?

Fair warning, I don't use Havoc. I use Lineage, here is how I install AOSP ROMs, (link) However, yes, on the final reboot would be when you install Magisk (Gapps as well if you need them). In theory recovery should already be installed, but installing it again won't hurt anything (installing recovery wipes out Magisk, so install Magisk after recovery if you do that). Remember you need Havoc on both slots (you don't want OOS on one and Havoc on another). So flash it twice.

Something didnt want to play when I was flashing... Got to flashing gapps and magisk, gapps flash gave me a error 64 and i got magisk installed, booted, now I've got no twrp and when I use fastboot it just softbricks then restarts after about 5 minutes, I'm gonna try booting from 3.2.3-2 as that was fine and hope I can boot into recovery and just go lineage I think for something new
EDIT
So I used fastboot --set-active=a, managed to get back to twrp so now its flashed on both again. In the process of flashing lineage now, hopefully this wont chuck another error at me for gapps
Okay so I've tried Pixel experience, lineage os , omni rom treskmod and couple of other custom android 10 roms, all stable and official and also updated ones, the wifi just simply doesn't work, wifi hotspot won't turn on either. I've tried every solution on the internet. I've even factory reset my phone using msm download tool and no luck(did this countless times).
I'm back in OOS 10.3.2 and there's no issue apparently.
At one point , i flashed a custom rom and the wifi didn't work, so I flashed OOS in the two slots and checked , the wifi works in OOS apparently, and never in custom roms.
Has anyone got this issue before and knows a solution?
How is your installation procedure?

I flash OOS and twrp on both slots, reboot recovery,
And then flash the rom and twrp, reboot recovery,then format data and factory reset, reboot recovery, if needed for some gapps, then reboot system

That's a lot of unnecessary steps. OOS on both slots, reboot to bootloader, boot twrp, format data and flash the custom rom, reboot bootloader, boot twrp and flash gapps, don't install twrp permanently if you are not going to install Magisk.

I need magisk too, I usually permanently install twrp
Also you think it's the way I'm installing at fault here? Or the rom? Or is it something wrong with my device?

Alright so got one doubt, I used OOS 10.3.2 to flash, should it be oos 10.0 only?
Thought that didn't make a difference.
I am also facing the same issue. Were you able to find any solution ?
So I found out treskmod omni rom and Paranoid android quartz 2 work perfectly , try those out, it still doesn't solve the problem in the other roms though. So not exactly a solution.
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!

Have you tried without Gapps?
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.

If you have a TMobile 6t I can confirm I have had to manually change the slots during the flashing process to get custom ROMs installed.

I found out that I do have the T-Mobile version that the seller flashed to International Software haha
When I reboot to recovery, I do see that the slots are being changed though.
Would you mind post the exact steps you took to successfully flash a ROM/GAPPS?
