Well, probably its a problem with your boot.img partition. Extract boot.img from stock rom zip, then flash it via fastboot flash boot boot.img and then, flash orginal recovery same as boot. Then, finally, flash via recovery STOCK ROM. Probably now it will be fine.
If not, try flash TWRP and make FULL WIPE included system partition and repeat upper steps.
Cheers.

In twrp goto wipe and do normal wipe remember don't do advance wipe otherwise it'll format internal storage as well so avoid advance wipe only do normal wipe then install full 3.2.7 zip and super su. zip

before you flash 3.2.7 mount system read-only. you can do this under "mount"
it is a known bug with twrp and oxygenos
You can download the stock boot logo from here: https://www.androidfilehost.com/?fid=529152257862664522

if you are on stock recovery you cant change the mounts.
flash twrp to flash bootlogo and oxygenos 3.2.7
otherwhise you have to install via sideload but this is very slow and you cant flash stock bootlogo
so flash twrp and then mount system read-only and then flash oxygenos 3.2.7 and after or before this you can flash the stock bootlogo

Cannot install 4.0.2 update

I was using 4.0.0 stock with twrp and root. Tried to install the 4.0.2 update but every boot just took me back to recovery. Tried wiping clean, no change. Tried installing stock recovery v2.0, recovery would hang. Tried using new twrp 3.0.3 and I could get back in, but any ROM, stock or not I installed, would not stick.. Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM. So in the end I flashed OOS 3.2.8 with twrp and then flashed stock recovery. At this point I'm pretty much at factory stock at v3.2.8 with stock recovery v1.0. Now I'm trying to update to 4.0.2 via OTA and for the 3rd time already I have received a installation failed message and rebooted to system. The first time I thought it was because I disconnected VPN after starting the download, so I downloaded a second and a third time. I don't want to resort to sideloading again because I fear I might get the same no OS installed problem I got when I tried to install 4.0.2 in the first place. Does anyone have any insight on what is wrong?

Steps:
1. Install latest Official or Modified TWRP ( 3.0.3/ 3.0.3 version 14 by eng.stk)
2. Enter into recovery. Connect phone to PC and copy downloaded ROM file.
3. Wipe everything in the recovery- Data, System, cache and Dalvic. It will erase everything.
4. Flash ROM zip after completing, don't reboot phone. Reboot to recovery again, and then reboot phone.
If u reboot phone directly after flashing ROM, u will loose TWRP.

Even twrp would warn me "no os installed. reboot anyway?" even when I had just installed a ROM.

This is pretty normal for nougat OOS. I've faced it for all 3 ROMs i flashed. Don't worry, your ROM was flashed successfully. You can mount and check the /system partition, you can see your ROM files there.
So here's what worked for me. (considering you are on ext4 /data)
1. Flash latest official twrp recovert ext4 version or use the file system swapper zip if it doesn't decrypt your data in recovery. TWRP has some issues as of now and mounts f2fs as default, so you just need to flash the file system swapper zip in order to swap it to ext4 by default.
2. Wipe /system /cache and dalvik cache.
3. Flash full 4.0.2 ROM zip, should be 1.4 GB in size.
4. Flash TWRP image again just in case.
5. Reboot to recovery, not to system.
6. Flash stable 2.79 Super Su and you are good to go.

Thanks for the tip, however I don't mind losing twrp, I only want to get stock unaltered update and this procedure does not help in this

Have you tried this guide: https://forum.xda-developers.com/oneplus-3/how-to/guide-flashing-oos-v4-0-1-custom-rom-t3537757
P.S. I think you did, but I'm just asking.

Thanks for the tip, but I fixed it. Ended up flashing v3.2.8 via twrp and installed OTA to 4.0.1 via sideload. Recovery would not boot unless first fully booted into the system. After that sideloaded 4.0.2 via OTA and now back to complete stock.
Thanks guys!

Update from 3.2.7 to 4.1

Hey guys. I am still on marshmallow on my op3. I am rooted and have twrp recovery. My question is what firmware/modem do I need to flash before I update to latest Nougat update and if my steps below are correct.
I would prefer not to do a clean install.
My steps would be:
Download full rom
Flash any firmware if required - this is what I need to know
Flash Magisk as I need root
Profit?

this is stock rom, you don't need to flash any firmware...
if you're coming from MM, i would recommend sideloading the rom, wipe everything, then go back to stock recovery then sideload then before 1st boot fastboot TWRP again, then reboot to TWRP and flash Magisk...Profit.
if you want to flash from TWRP without going through this (which i don't recommend), make sure in TWRP to format data as f2fs, wipe everything then flash the rom, and then form TWRP flash TWRP again, then reboot to recovery (not system), then flash Magisk.

Thanks a ton for replying. Another question for you. I get the OTA notification. I could just let that run and flash twrp after the installation right.

if you're already rooted it wont install..and you can't flash the small ota file from TWRP, you have to flash the Full rom (1.4 GB)...
how you download is up to you, but why download from the update when there's many links available around !

Thanks for all the help. I flashed the new update successfully.

Root for OxygenOS 4.1.6

Hello everyone, I am using OOS 4.1.6 on my new 3T, however I am unable to get root even though I have already tried with latest TWRP, magisk 12, and SuperSU 2.82. Nothing worked everytime I've got not rooted on root checker.

Please describe in steps what you did.

Hi,
We unclocked the bootloader, then we did flash with twrp 3.1.0 and installed SU 2.82.
After doing all this, the phone was not restarting.

Well first of all, format your whole phone over TWRP. (System too, but make sure you have the full Oxygen OS zip on a computer.)
After formating all partitions, move the full OOS zip and Magisk 12.0 on your phone. Flash the OOS zip, restart your recovery and flash Magisk after it.
That worked 100% for me all the time.
If you still need assistance with that, we can setup Teamviewer so I can guide you through this.

Same here! The phone freezes in boot animation screen. Even the animation stopped!

Guessing it's about the f2fs file system. I used to have a situation like this with Oneplus 2. My step was to format data and cache partitions back to ext4, and that worked.
Using 3t now, still not rooted. Don't want to start over after bootloader unlocking

I had the same problem and was solved with twrp 3.0.4-1 and SuperSU-v2.82.

Ok, I will try and update here then.

I'd say wipe everything possible in TWRP except for system partition, then boot the system and then eventually flash some kind of a root package - either Magisk or SuperSU. I always do it that way and it works. I am not really sure but otherwise it might have something to do with the data encryption.

Use following and you should be all set (just did it 2 days ago):
1st Flash Stock Recovery (go back to stock - https://forums.oneplus.net/threads/...-3-3t-and-go-back-completely-to-stock.456232/
Flash TWRP after you achieve STOCK OS 4.1.6.
Use this TWRP version for now (there is some issue with 3.1.1-2 i saw on forums):
twrp-3.1.1-0-oneplus3t.img
To Root just use Magisk-v13.3.zip (IMO way better than SuperSu + has MagiskHide for AndroidPay/Snapchat/SafetyNet checks):
https://forum.xda-developers.com/apps/magisk/official-magisk-v7-universal-systemless-t3473445
That is it, done!

Flash twrp via fastboot.
Boot to twrp via
Fastboot boot twrp.img
Replace "twrp" with the file name of your twrp.
Once twrp booted, go into reboot menu. And reboot to recovery again. That will make your phone boot again into twrp, but this time with more rights.
Go into wipe. Advanced wipe
Change data partition file system to ext4.
Reboot again into twrp via the reboot menu ,just like before.
Now go into wipe again, and format system,data,dalvik and cache.
Flash your rom.
Flash gapps (if not otherwise stated by ROM thread)
Flash Magisk (optional, if you want root)
Wipe dalvik and cache.
Reboot. And enjoy

We only have one bootloader.
We have different firmwares though like nougat and marshmallow.
You will need Firmwares S244 for nougat ROMs.
That firmware must be flashed through ota. Stockrom-feature. Simply using twrp does not count as doing otas.
Basic starter things: Have Firmware S244 or S251 installed through stock ota feature.
Then use my earlier stated instructions.

Thx alot it worked & no problems
