I'm with last OB4 and tried to restore the nandroid backup done with A10.3. The restore was completed without errors but at reboot the phone restarted always to TWRP recovery.

I tried to reflash magisk but the result was the same. My experience has been for many years on single slot phones, so I have some doubt on the correct methods to restore an entire rom with TWRP. Do i need to restore twice for each slot? thanks
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Timmmmaaahh!:
Exactly. When poo hit the fan, there are very little situations that your bootloader will fail to load so that's always a handy backup and with fastboot commands you can make a lot of magic happen. One of those things is switching A/B slots but there's a plethora of other resque methods.

Oh and if it's been a while, make sure your fastboot is up-to-date by downloading latest SDK Platform-tools.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Arkmars20:
Thanks. OOS 10.3.0 is very stable so haven't had any issues installing mods. I wasn't aware of all these fastboot rescue commands. I'll check it out

I need help installing Android 10.3 on a friend's Oneplus 6T (on which OOS 9.017 is installed). I would like to confirm that the following steps are correct:

1) - Boot to TWRP

2) - Flash full ota

3) - TWRP flash 3.3.1-30 installer (TWRP 3.3.1-30 Q Unofficial by mauronofrio -> is it correct?)

4) - Reboot to recovery

5) - Flash Magisk 20.3

6) - Reboot to system

Thank you all

Sorry, I forget to mention that it would be better to flash first the magisk uninstaller before flashing the rom.

The sequence I follow is the one from the OP of this thread and I don't have normally problems flashing with this procedure (TWRP user):

Is nandroid backup/restore working? If so are there any special steps that need to be taken?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Vortell:
I recommend the thread dedicated to this issue. Not sure where it is sorry. I read it through a link somewhere else. The other thing you should think about though is getting a USB c thumb drive, an otg adapter and standard USB thumb drive or as I did micro SD to USB into said otg adapter. I actually use USB c to USB c and two phones for fastboot/ADB as well. I have also successfully used droiddrive to emulate thumb drive and used another phone for backup through USB c to USB c cord as too. So if u have an old phone you could do that with right cables. I did it with old phone using USB c to micro SD. So there are a bunch of options. The best for you might be to use ADB push to move the file from computer to your phone. Most TWRP builds have this. I have not tested this on TWRP for this phone.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Causical:
Nice, I've always wondered about this. So what, do you just use a terminal emulator to run fastboot/adb from?... I'm think you need some sort of mobile SDK tool right?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Vortell:
Yeah you need the tools on Android. The easiest way to do it is install magisk and then install the Abd & fastboot Android ndk module in the manger. Then either terminal emulator or termux. You need root access so use su to elevate to root user. Ie: su adb devices. I have yet to find a good rest to install framework/lib/binaries that will let me run full Linux programs easily. I'm to lazy to fully compile something like Arch Linux on my phone. I want to run full Firefox. So I can bypass the widevine loss from unlocking bootloader. Userland kind of works. You can use droiddrive to boot Linux on computer! It even will spoof DVD/cd drive.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Causical:
Yeah I actually used drivedroid to install Linux Mint on my laptop, I love it... It took a moment for me to realize it wouldn't install on the hard disk because of the SATA controller, but luckily I figured out I could just boot safe mode on windows, change it without losing windows OS and now I've got dual boot set up.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sronweb:
Unfortunately it didn't worked for me. I tried to restore a nandroid but, at the completion, it finishet without errors but at reboot always returned to TWRP.

But I didn't remove the security (password, fingerprint) in the nandroid backup.

Perhaps it's necessary to remove them and then it should work. Anyone that can confirm it?

I'm using TWRP on previous phones based on single slot memory and with external SD card, so I'm not sure about the correct procedure on our phone.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] urgali:
When restoring, make sure you only restore rata partition, avoid boot and system

Had same issue and I solved this way
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sronweb:
So, it does nothing to do with the encryption (fingerprint etc). Isn't right?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ogkillergreen:
So we backup everything and just restore the data partition?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sronweb:
Just to make sure. According to guides here on this thread I back up the following:

- Boot

- System Image

- Vendor Image

- Data (exc. storage)

- Modem

- EFS

Skipped from backup:

- System

- Vendor

To make it working I understand I should restore everything except boot. System is already skipped in backup.

I may try asap. Thanks to confirm it.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kevk60:
From what I have read and past experience, it is always recommended to disable security before making a nandroid backup
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sronweb:
I read it too but I knew that it was a problem on the preliminary versions of TWRP. In theory it should have been fixed since some time as I understood.

In my past experience on previous devices (HTC, Samsung etc) I never had to remove the encryption. But I know that the memory partition was different, no dual slot, and also the Android version is different.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] kevk60:
Thanks for the input. I know years ago with my Nexus phones and custom ROMs it was mandatory to disable the security before making a nan bu. The only reason I still do it is to be safe. Only takes a couple of minutes to do and I know then I will not have any problems. I got bit a couple times by not doing it. Have a good one.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Arkmars20:
What does 'disable security' mean? I tried recently to backup all partitions on OOS 10.3.0 in TWRP then later when I tried to restore it wouldn't restore the data partition. I'm on OOS 10.3.1 now with Magisk 20.3. What would you recommend using to do a complete backup? I tried titanium backup (paid version) & had issues with that as well. On my OnePlus 5T in TWRP I was able to backup everything and restore but that device didn't have A/B partitions
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Hp6t:
Mostly working

Thanks for this guide and all the work you put into development, and all the knowledge everyone here shares, I am greatful. First timer here. I have used a few different guides here to get to where I am. I have a used (amazon certified) tmo 6t. I used msmtool to go OOS 9.0.11 and unlocked bootloader, then got twrp 3.3.1-1 and installed Lineage 16. Had some boot issues so read up on the a/b slots and think I understand them.

I have lineage up and running on slot-a but I have never had a good boot where slot-b was the active. Slot-b always goes to fastboot.?? I cannot install to slot-b. I re-traced all my steps that worked for lineage on slot-a, but made sure to install the rom on both slots and reboot system while on slot-a inorder to boot to slot-b, which then goes to fastboot, then I reboot to recovery and twrp shows I'm on slot-b as the active slot, so twrp works on slot-b, so why not the ROM?

Order of operations:

(Auto updates turned off)

1. In twrp -format data

2 reboot revovery

3. Twrp fastory reset

4. Adb push .zips

4. Install Los then twrp

5. Reboot to recovery

6. Install Los then twrp

7 reboot to system,: if its slot-a then Los loads, but if its slot b it boots to fastboot....

I've tried all I can think of and hope I have done the required amount of reading/searching before posting

Can a slot be broken? But if it was, twrp shouldn't still work on it right? The msmtool would have fixed it? I did start back from there trying to figue this out.

I was initially contemlpating going stock Lineage for the simple updates but now I'm dirty flashing everything on slot-a. I'm at a LOS (pun intended)

Any insight/help will be greatly appreciated.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] TENlll423:
when they talk about security they are meaning if you have a pattern or pin setup disable that before entering recovery..
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] sronweb:
I guess you are right. I had a chance to review this point with [MENTION=4712355]mauronofrio[/MENTION], who confirm that is better to remove the security for back up and restore. I will follow this steps for the next backup.

I have a question. My phone is a OnePlus 6T currently on OOS 9.0.15 build ONEPLUSA_6013_41_190625. I am rooted using magisk 20.3 (20300) and I have magisk manager 7.51 (267), also my recovery is twrp 3.2.3.2

I would like to know what is the safest way to update my phone to the latest OOS OnePlus6TOxygen_34_OTA_042_all_1912142031_b9f0d133d6884048.zip

I downloaded the complete zip from OnePlus website and I also have a copy of Magisk-uninstaller-20200110.zip and Magisk-v20.3.zip on the root of my 6T storage.

Basically what I want to know is, are the steps below the proper way to update my phone?

1- do I just reboot to recovery (twrp.3.2.3.2).

2- flash the OTA that I downloaded from OnePlus website.

3- flash twrp_3.2.3.2

4- flash magisk-v20.3

5- wipe dalvik cache

6-reboot system

Please advise and thank you in advance.
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Striatum_bdr:
Why do you absolutely want to use an outdated TWRP?

ALWAYS LATEST VERSION

You method won't work as you don't respect the rules for an A/B slot device. You must reboot to recovery after 3- to switch to the newly active slot and flash Magisk on the right slot. What you do will flash Magisk on the 'old' slot.

Why don't you just, without rebooting to TWRP:

- update with local update

- don't reboot

- in Magisk Manager, flash latest TWRP as a module, install Magisk on the other slot (in that order to be sure to have Magisk, as installing TWRP erases Magisk)

- reboot

Why do you need TWRP by the way?
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] rfvreynoso:
I apologize as in #3 I mean to write twrp-3.3.1-31-fajita-installer-mauronofrio.zip

That's the latest one that I have. Please advise if that is latest. I do not want to use an outdated twrp.

Also I was unaware of the method you pointed out for me where magisk manager has a twrp module. I like to have twrp as I do a complete backup of my phone from time to time using twrp.

So I can do steps like this:

1- Reboot to recovery (currently twrp 3.2.3.2)

2- Flash latest OTA, I got oneplus6toxygen_34_ota_043_all_2001151910_ab93e4deb6c1b.zip

3- Flash twrp-3.3.1-31-fajita-installer-mauronofrio.zip

4- Reboot to recovery

5- Flash Magisk-V20.3

6- Wipe Dalvik cache (unsure if needed)

7- Reboot system

Thanks for your reply and advised. Will this work ? Also with your method, do I just keep using that method to update future ota releases ? Could I boot into twrp to do a nandroid backup that way too ?

Thanks in advance

---------- Post added at 10:41 AM ---------- Previous post was at 09:48 AM ----------

Also, in my readings I found out some information about this file >> OldKeymasterFlasher.zip.

Is it necessary to flash this file for Android 10 update using twrp and root or not ?

What is this file for ?

As far as I read it mentions to flash ota in twrp and then flash twrp and then flash OldKeymasterFlasher.zip and then reboot back to recovery to flash magisk.

Is that how it goes ?

Thanks in advance.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] ZerBri:
Hello,

if I have installed TWRP.img (ramdisk) and want to restart from TWRP directly into recovery TWRP, I automatically end up in the recovery of LOS.

I only get into TWRP when I start fastboot boot twrp.img via adb.

Apparently I have problems with the slots here. Maybe TWRP on _b, LOS on _a

How do I get a handle on this? It's already put me in crashdump mode.

[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Oblias:
I just finished reading through more than 5 pages of thread search results regarding the question of will this great version of TWRP now successfully make, and then restore, a nandroid backup. I lost count, but I would say a good guess is that the question has been asked more than 50 times, at least. After reading all the results of my search, I come away with this..... I'm still as much in the dark as I was when I entered the search query.

So, I'm going to make it the 50+ time the question gets asked. On my OP6T, running the newest twrp-3.3.1-31 version from this Dev, is it possible for me to make, and restore a nandroid backup? Next to flashing files, I would say this is the most important function of TWRP.

The closest I got to an answer, and to me it wasn't that close, was to make a backup of all partitions except Vendor and System, after removing all security. But then in the very next sentence it was advised that when it came to restoring that backup, that the only thing that should be restored is the data partition. It makes no sense to me why it's required to backup all those other partitions, if all you can do is to restore the data partition.... Anyone see my confusion and dilemma here??

Does there exist a simple, straight forward answer to this question. Is this TWRP able to do a reliable backup and restore in Android 9.0.17 ?? If there is an answer that includes 'yes' in it, what would the EXACT steps be to obtain that goal?

TIA !
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Arkmars20:
I've tried many times to make Twrp backups including all partitions (over 10GB) but can never restore, always fails. On my OnePlus 5T with OOS I used to backup all partitions and restore if I needed to on Android 8, 9 but no luck on my OP6T with OOS 10. I've asked for help a few times to with no feedback. Apart from that Twrp works fine
[OnePlus 6T  ROMs, Kernels, Recoveries, & Other Dev] Oblias:
I completely understand. On every OP I've had, from the OPO to the OP5T, TWRP did it's job. Now, on the OP6T, seems as if it has lost some of it's starch... I'm convince it has to do with the A/B partitioning, but my way of thinking leads me down the road that says if they can get a MSM tool for unbricking, a MSM tool to convert the TMO to a International version and cut the strings of T-Mobile, then this would be something that would have been dealt with long ago. I'm far from being a Dev, but over the years, I have seen what these fine Devs are capable of.

Which leaves me even more stumped as to why we are still dealing with making and restoring a reliable backup after 2+ years.....

Don't get me wrong, I'm far from complaining! Anything made available on this superior forum is a great gift for us. I just sort of got used to the gift that TWRP used to provide for us..... :)
