How can I get to Android N preview 3 from a custom ROM and rooted?

I don't have a PC either but I have TWRP installed!

the only way if to find someone who does a full TWRP backup of Android N (untouched) and upload to you.
you put it in TWRP folder and restore it. then you need to flash the boot.ing for android N.
it is a long way and I doubt you will find a backup uploaded since it is around 5GB.

Download the DP3 image from Google then unpack it and transfer it to your phone. You can flash system, boot, and vendor in TWRP 3.0. The radio must be flashed in fastboot. You will want to do a factory reset before flashing N IMG's. If you want continued access to TWRP after flashing Android N, you must be decrypted. TWRP does not work with Android N unless decrypted.
Alternatively, use fastboot to install the factory image. You still need to be decrytped to use TWRP on N.

How can I install a decrypted version of N?

Fair warning. I have not done this nor do I use N previews. I am decrypted on MM though for several months. Also, I strongly suggest having a PC on standby so you can troubleshoot any issues that will arise.
In TWRP, do a backup then transfer that to a backup device. While in TWRP 3.0:
-Flash the vendor and system from N DP3
-Flash this DP3 modified boot
-Flash SuperSU 2.7x
-Wipe internal storage via TWRP. This step erases everything from your phone and is necessary to remove the encryption. Fastboot format userdata also does this from a PC.
Once you boot up, the phone should indicate you are not encrypted wherever that is located in Settings. If done properly, you should still have complete access to TWRP 3.0.
Notice that radio and bootloader are not mentioned. It is my understanding these have been updated in DP3. You need a computer to flash these two files. If you notice signal issues or anything like this, you are using older radio and bootloader combo than is specified for DP3.

OTA updates with TWRP?

I really want to have TWRP installed on my device and have OTA, is there anyway I can achieve this, maybe a flashabe zip that updates the device?

Let's start from the scratch. Unlock the bootloader and grab latest recovery image. Put your device into fastboot mode. Now boot into recovery temporarily and don't flash twrp. Now go to Backup and take a backup of Boot partition (make sure it's completely virgin). Now you can flash twrp and Magisk if you wish. When an OTA comes in, just reboot to twrp and restore the boot partition. Now your device is free from twrp and magisk and ready to get OTA update. But make sure you don't play with build.prop or uninstall any System app or play with System partition.If you change anything on System partition, you need to un-change them before trying to get OTA update. Boot partition will only help you to get rid of twrp and magisk. But if you wanna play with System partition, it's better to take a complete nandroid backup the same way I told you.

So when I boot TWRP to backup the boot partition, I should keep read only?

Don't worry about it. When you boot into twrp (temporarily), just swipe to allow modification and head on to Backup and take a backup of boot partition. Thats it.

[Help] Stuck in fast boot- boot loader after restoring twrp backup?

[Solved (look at bottom of post)]
so, hopfully this is in the right place.
Following the procedure I've done on my nexus 6p many times over; I created a TWRP backup on my 6t then tried restoring the backup I made with twrp and when it finished I pressed reboot to system. The device then only booted into twrp. I saw it was on the "a" partition and I knew I was previously on the b partition so I manually switch partitions and now I'm stuck in fastboot boatloader I have tried flashing a temp twrp.img but im getting an error "FAILED (remote: 'Failed to load/authenticate boot image: Load Error')" in fastboot
After that I switched active partition in fast boot and got into twrp but my data appears to be encrypted and after restoring sys,data,efs,vendor (skipping boot as it holds the recovery now) I only have fast boot in both a/b partitions. I'm going to try to fast boot twerp then install twerp permanently and see if i can get a wotking twrp if not then ill have to get a factory image to get back to stock but was hoping to get some data off but whatever..
I'm kind of new to this a/b partition setup. any help is appreciated.
Edit: for future reference All I was doing was trying to restore a backup? how do I restore a backup on an a/b partition system? As far as I know I did it right...
1) remove lockscreen pin ect..
2) backup boot,sys,ven,data
When restoring
1) mount partitions
2) select restore backup and restore all .....
What am I missing?

Solved:
twrp for 6t is borked when it comes to backing up/ restoring...
The version in question: twrp-installer-fajita-3.2.3-1.zip
I restored my 6t to stock with msmdownloadtool and reinstalled twrp then made a test backup. After restoring it I was left in a twrp bootloap and encrypted data partition.

I don't think you should ever need to manually switch slots.
If you are on slot A, and flash an update, it will install to slot B. When you restart your phone, it will automatically switch to B for you.
Also, you shouldn't be flashing the TWRP.img, but booting it instead.
You could try starting fresh with the msmdownloadtool which is found in these forums.

I'm currently stuck in TWRP with encrypted data after restoring a backup. I didn't know you couldn't restore backups on this phones. That sucks. I guess I'm going to have to start over now. That really really sucks.

Yup, I felt the same.. it's a huge bummer especially when you get it all set up and perfect. Use msm to fix it if you can't use twrp. Hopefully twrp gets fixed soon (I'm really surprised I can't find more people who have noticed this or even twrp team talking about it) for now Im waiting for proof it works on the op6t. I even tried to use Chainfire's flashfire to make a backup and.. no it doesn't work.

Use Msm download tool:
https://www.google.com/amp/s/forum....-msmdownloadtool-v4-0-oos-9-0-5-t3867448/amp/
I think that's the right post but make sure it matches your device. I used msmdownloadtool around 6 time just testing twrp and only had one hiccup where Msm wasn't detecting my one plus 6t but I eventually got it working.

use the other twrp unofficial but problem you had with would be fixed with big file system fat32 can't do it right

Could you post a link to it and are you sure? I used the unofficial version so which one are you talking about? I'd really not like to have to re-setup my daily driver from scratch.

https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482 your using early version of twrp the black one is made by same guy download unofficial twrp.zip not twrp.img reboot recovery flash twrp.zip then magisk it may work if not then format data (erases phone) then twrp,magisk reboot recovery to see if it stuck I flash magisk again when it starts up go to magisk thread get the manager 18.1 don't insall it

Which one? I've tried the 3.2.3.28 last and restoring didn't work. Should I try the most recent installer in the list? And can you confirm that backup&restoring works on the one plus 6t? Also is there anyway to backup my phone without twrp before I try this? I'd really would not like to have to use msm again?

sorry that didn't help format data then flash twrp then magisk should boot without msm
---------- Post added at 01:06 PM ---------- Previous post was at 12:52 PM ----------
i had to use extfat format on htc 8gb backup to get it to work maybe devs will fix that

Has there been an improvement on twrp for the 6t yet? Just curious if I can rely on a backup is there any updates?

[STOCK PIE (march)] Will I get my data wiped if I hotboot TWRP?

Hello, I've been trying to root my phone, I followed a guide that tell me to
Code:
fastboot flash twrp.img
and got all my data wiped for some reason. LATER, i found out that you souldn't be doing that, instead you should be doing
Code:
fastboot boot twrp.img
But by then, I got everything on my phone deleted (i flashed an original rom from MI forums and restored a manual backup of data and some apps i had, but still I lost like a day setting up everything).
My questions are, if I hotboot TWRP will I get my data wiped again? (my bootloader is still unlocked so no danger there)
If not, can I backup my data normally using TWRP GUI on hotboot?
Also, once I've installed magisk, will I stop receiving OTAs?
Thanks

No, you won't get data wiped if you boot twrp. I'm doing this periodically and everithing is ok.
Probably you flashed twrp wrong. It should be
fastboot flash recovery twrp.img

You can receive ota's with magisk. Prior to installing ota, you should uninstall/"restore partitions" with magisk but not reboot. After ota is installed, you install magisk into secondary partition (with magisk manager) and reboot.

But isn't HIGHLY recommended to NOT flash the recovery?

I'm not flashing it too, just "fastboot boot" it when I need it.

I hotbooted TWRP and made a backup, after rebooting from TWRP, the phone boots slowly and hangs at the lock screen. Any ideas what could have triggered this?
The only "abnormal"thing i did was to rename the media folder in "data" so TWRP could include it into the backup. After that I renamed the folder to "media" again, and rebooted.
There was a "mediadrm" folder, but I don't remember if it was already there or not.

Why do you want to include media folder into backup? It has only mount points to sdcards. Do you want to include sdcard content into backup? Where is backup stored? On the same sdcard which content you backing up?

Media folder has internal storage. Anyway, i was able to boot again by flashing to latest stock rom and then restoring "data" from my backup.

On Mi A1, TWRP can't be flashed from fastboot, because it doesn't have /recovery

TWRP can't stay, even flashed by installer

Hi guys,
I'm not newbie with flashing but this one I don't understand.
Probably I've done some mistakes with flashing/install/uninstall of roms/magisk/twrp.
Now I'm stuck with TWRP and can't boot into system because of something.
Every time I run TWRP and try to install all my files are encrypted, no matter I install TWRP by .img or .zip. Only working TWRP with decryption is temporary one, by "fastboot boot twrp-3.3.1-6-fajita.img" command. But when I flash it by regular .img file by this tut (https://forum.xda-developers.com/on...overy-unofficial-twrp-touch-recovery-t3861482), after reboot it's back like 3.3.1-6-fajita version, BUT without decryption skills.
I thing I done some mistakes with uninstalling magisk ect. but I think it doesn't matter.
I tried to uninstall magisk by Magisk-uninstaller-20190204.zip on both slots, I tried install all again in regular way (install temp TWRP through fastboot command, install TWRP through this temp TWRP, install full newest OTA .zip, install TWRP again (I know I shouldn't but I tried both combinations - .zip and .img) and install Magisk and at least system reboot. But when I rebooted between OTA and Magisk (like guide tells) TWRP can't decrypt files. No matter what I've done nothing helped.
What can I do that I have not done yet? Of course, all is about I don't want format my data and re-install all from the scratch...
So... tell me, is possible to make TWRP great again?

Is everything only showing as encrypted when you try to restore a backup? I've been booting the img via fastboot then flashing the zip as it seems you have and it's been working fine as far as it staying installed and not showing all my files as scrambled, I also made the mistake of using Magisk uninstaller at one point, that didn't end well. Seems these A/B phones are temperamental as hell. I read somewhere else that doing backups to USB storage my be more reliable for a backup restoration, not sure if that would effect the encryption issues or not but I may have some time to test that tonight.

I've done that too - not helped. I restored my full nandroid backup by fastboot temp recovery (as I wrote, only this one can decrypt my files) but I've got "You device is corrupt"... and of course TWRP can't decrypt my files.
