TWRP suddenly stopped flashing .zips - OnePlus 3T Questions & Answers

Hello!
My TWRP stopped flashing ZIP files. When I try to install some archives, the message pops up:
Code:
mount: no mtd partition named "system"
but installation continues and completes normally. For some packages there is no such message, but always when I load in OOS, no changes were applied, for example I can't see apps that should be installed, or the bootanimation stays default.
In TWRP itself I can mount and modify System partition, and there are new files after flashing which should be able to work in system itself, but they are not. Even in system I can see necessary apps in /system/priv-app, but they won't load.
First encountered today when I needed to fix Magisk Safetynet checks. Tried installing different TWRP recoveries, but I end up in no real flashing ability. Please help!
Now on TWRP 3.1.0-1, OOS 4.1.6 stable.

How to use Magisk??? (add lost txt)

Hi to all
I have rooted OP3T and every time when I install new update, BETA small or full version zip file, I need again to install stock.zip from boatloader , then again, install TWRP and Super Su.
I hear that with Magisk I can easy install any update without lost TWRP and Root. I have flash Magisk and install from Google Store Magisk Manager.
So my question is how to install new update with Magisk and dont lost TWRP and Root?
Please tell me step by step
thx a lot for your answers
Magisk doesn't touch the recovery. And you'll still have to flash the Magisk zip since the boot image is updated whenever you update your system (Magisk modifies the boot image).
What does stay after an update (as long as you don't wipe /data) is any Magisk modules that you have installed. If you have a bunch of modules that change build.prop values, debloat system apps, change screen density, replaces system UI sounds, etc, you won't have to do those changes again after an update. They are found in the Magisk image in /data and will be loaded by Magisk at boot.
Even if you've wiped /data, it's just a matter of flashing the Magisk and module zips in TWRP after updating your system. No tedious manual editing of build.prop or deleting apps, etc. It literally takes seconds...
If you have issues with loosing TWRP after an update, you can easily fix that, right after updating. Just keep a copy of the recovery image on your device and flash it in TWRP.

Are there 2 copies of /system on the phone?

My phone (3T) has an unlocked bootloader, is encrypted, not rooted, and running stock OOS 5.0.
I flashed TWRP and discovered that stock OOS restores the stock recovery in boot.
I saw the Oreo dm-verity thread by xenet, had a look at the zip file, noticed that it just modified fstab to prevent force encrypt, so I flashed it to see what happens.
And nothing happens. After the system had booted, fstab is unchanged from the original stock copy.
So I'm wondering whether this file is also restored when booting up on stock.
I get aggressive and go back to TWRP and delete /system/etc and /system/bin and modify build.prop.
Surely now the phone won't boot!
Wrong! It boots up and everything is back to normal in /system.
I go back to TWRP and have a look at /system and it shows me one without the etc and bin folders and has the modified build.prop.
What's going on? How can I see one version of /system in TWRP but a different version (ie, stock) when the phone has booted?
By the way I've been an Android user for many years and have rooted and flashed custom ROMs on a variety of phones and I've never seen anything like what's happening on my 3T. I'm sure that dm-verity is somehow involved in this.
Happened to me on my earlier OOS 5.0 attempts...
But i suspected Magisk is involved in my case.
I downloaded Magisk Module "System Terminal Debloater,"
remove some apps like Duo, Chrome, and Google Play Movies.
Some restarts, they magically re-appear again on Apps Drawer...
Haven't touch them yet again after....

I should have mentioned that I'm also not rooted. So stock OOS 5.0.

When you boot TWRP for the first time, it should ask you if you want to put the /system in read/write mode or if you want to leave it unchanged, did you choose the right option?

No, I don't get that message because my phone is encrypted with a password. So the first thing I see in TWRP is the request for the password and then I'm presented with the menus.
However, in the Mounted menu, system isn't mounted and I have the option of mounting it in read-only mode.

After first time flashing TWRP a folder gets created on your internal storage, with a hidden file called .twrps, go delete it and reboot recovery to trigger the message "allowing system modifications" on TWRP's first boot...
It's not about encryption, it's just that TWRP remember the decision you made due to the file I pointed out...

Thanks, you are correct. I'd forgotten that that TWRP remembers. Deleting .twrps does bring up the RO prompt after decrypting storage.

I had allowed changes to the system otherwise I couldn't have made changes to it, which includes the ability to restore the system partition.
But I'm still unclear why if I make changes to the system partition and boot with the stock kernel, then after the boot none of the changes are present in the system partition, but if I boot back into TWRP then the changes are all there.
I recall someone in another OOS 5 thread saying that the stock kernal replaces TWRP with stock recovery if you don't flash root (magisk/superSU). Is it possible that the kernel re-flashes system on boot? Another possibility is that TWRP thinks it's making changes to system but it's not actually? Not quite sure, I've never heard of anything like this before either, just throwing other ideas out there.
I've never read anything about the OP3T or any oneplus phones for that matter having A/B system partitions like the pixels. *shrug*
@nhshah7, something's like what you suggest must be going on to account for what I'm seeing. I'm hoping that someone can confirm my observations and provide a definite answer.

Actually it doesn't explain how TWRP can make changes to system yet the phone boots up on an unmodified system if using the stock kernel. And then, when you boot back into TWRP and look at system, the changes are still there.
Where does the unmodified system come from?
Where does the modified system live?
Why doesn't modifying system result in a failed boot due to dm-verity, while restoring a backup of system does result in a failed boot?
So many questions with no answers.

Not sure if this is applicable in your case but the following possibilities may be worth considering for you:
1. Are you sure that the system image is actually getting modified? If the system partition is not mounted before flashing the zip and the zip being flashed does not mount the system partition in read / write, then no changes to system partitions will actually be written.
2. If dm-verity is enabled, then restoring system could result in an error as this is different from restoring a system-image (nandroid copy of the whole partition and not just the files in the system partition). DM-verity can be triggered if the files are all the same but the dm-verity signature computed by hashing the system partition has changed.
3. For boot partitions, strange behaviour can occur if remnants of the previous boot.img are still in the partition (...e.g. if the previous boot.img was of larger size and a new boot.img of a smaller is flashed, then there will be some bytes after the new boot.img that are from the previous boot.img). To verify this, format the boot partition from fastboot and see if you notice anything different with the new boot.img.
4. In Oreo / 8.0, dm-verity flags are stored in dtb (device tree blobs) inside the kernel and not in the fstab file. Only data encryption can be changed from the fstab file and dm-verity needs to be changed from changing the dtb (...Magisk beta v1456 and SuperSu 2.82 SR4 do this, I think).

I'll come back to 1.
2. That makes sense and accounts for why a restore of the system partition with the stock boot image causes me to get dumped back in fastboot mode. If I flash the stock system zip file then the system boots properly.
3. I've not had any issues with strange boot behaviour. I'm always starting with stock or flashing kernels that modify the stock boot image, like Blu Spark.
4. I gathered this from my reading of various threads. If I want to make changes to the system partition and get them to stick and not fail dm-verity then I have to flash a custom kernel. I've proven this in my testing. (A rooting solution would also work, but I've not done this).
Back to 1:
Here's what I've done:
Starting with pure stock image (flash OOS 5.0).
Boot into fastboot and flash TWRP.
Boot into recovery.
Mount system as rw. (In ro mode the next step fails)
Delete the bin, etc, and lib folders in system using the TWRP file manager. (Screenshot a)
Reboot system.
... First interesting fact ...
System boots ok, deleted folders are present in file manager. (Screenshot b)
Boot into fastboot and flash TWRP. (Booting with stock restores stock recovery)
Mount system.
... Second interesting fact ...
TWRP file manager shows that deleted folders are missing. (Screenshot c)
Flash custom kernel or patched boot image
Reboot system
... Third interesting fact ...
System fails to boot. Hangs on splash screen.
So TWRP made the changes (otherwise how could they be visible between reboots, including a replacement of recovery) and I only did them once.
Yet they don't actually take effect until I replace the stock boot image.
So, where are the changes hiding? What did TWRP actually change?
Screenshots (note that TWRP has the wrong timezone set so the time shown is wrong):

Some more thoughts for you to consider:
1. Have you tried this with the official TWRP recovery version 3.2.0-0?
2. Is there anything inside the folders that you see using the file manager after a regular boot? Folders of same name may exist in the boot ramdisk and these are merged with system folders after boot.
3. Try wiping cache between reboots and see if that changes any of your observations.

Good questions. They got me thinking more about how this could possibly work.
I had a look at the cache and there's definitely no copy of the system hiding there.
I also unpacked the ramdisk in the boot image and it had nothing in system. Furthermore, the boot position is only 64 MB, no where near enough to hold the system.
Then I installed Magisk so that I could browse around the phone's partitions and take copies.
I learnt two things from this:
1. If there's a second copy of the system there are only three partitions large enough to hold it (/proc/partitions shows the sizes in 1 kB blocks). The system is about 1 GB. There is space in the system partition (sde20) for 3 GB. There's also space in the data partition (sca15). And there's space in the major partition holding the modems (sdf).
I could eliminate the data partition by formatting it but restoring the internal storage (sdcard) is such a a pain.
So I'll just accept that there is space for a copy, but I'm unlikely to find out exactly where.
2. When I had Magisk installed installed and the system boot, I added a folder and file to /system/priv-app using a file manager (so not using TWRP). I then booted into recovery, flashed the stock boot image, and rebooted. I was expecting it to fail dm-verity (modified system) but it didn't. After booting up there's no evidence of the folder I added to priv-app.
And if I restore the Magisk boot image then the additions show up again.
I'm actually very impressed with how the stock system (kernel, recovery, system) protects itself from modification. Very cool!

How to? MAGISK for Oreo Exynos

I failed similar times to root my phone with twrp 3.2.xx and 3.1.xx. I used Odin 3 v3.13.1.
Any ideas or thread links for the young padawan?
I appreciate your advice masters :good:
Using Odin Flash TWRP latest from the note 8 TWRP thread here on XDA, one on their site is not latest.
Install magisk manager app from play store.
Download magisk from the app.
Reboot to TWRP and flash the magisk file just downloaded.
Reboot and check magisk manager for root and hide.
Should be good.
Nope. Not working and still ends in a bootloop and it's unable to mount the internal storage.
Something went wrong, so.. my phone is unable to boot the system after that!
The issue is the version of TWRP and Oreo, its not yet compatible on this device, it needs porting over
If you want MAGISK you need to do it all in one hit.
Flash TWRP
Select Read Only Option.
Format Data
Reboot Recovery
Flash the DM Verify Encrypt file
Reboot Recovery, You could be able to flash files wihtout a Data mount error.
Now flash the files you want, i..e MAGISK
Once you have booted the ROM and return back to TWRP you are unable to mount Data.
This can cause various issue when flashing files
Funny you.. How can I format if the internal storage isn't able to mount?
"Select Read Only Option.
Format Data" <-- seems like a contradiction to format a missing
partition.
I think we need to wait until someone will port the twrp for Oreo. cheerio!
Because it needs to be done when you first flash it.
Once you have flash Oreo, Then TWRP, You boot into TWRP and format. You then Flash the DM Verify.
Data is accessible, its empty but accessible, Flashing any files like MAGISK work without any errors.
I have it all working on mine without any issues, I do know if i need to flash any additional files it wont work properly due to Data no longer mountable.
There is a updated version of TWRP that fixes this, but its not been ported over.

Magisk Install Error - insufficient Partition Size

Hello. I'm attempting to install magisk on a Samsung Galaxy Tab 4 10.1 (SM-T530NU). Base android has been replaced with crDroid (crDroid-7.1.1-20170312-v2.3).
When I go to flash the magisk .zip via TWRP the log reads:
...
-Flashing new boot image
! Insufficient partition size
- Unmounting partitions
Updater process ended with ERROR: 1
Error installing zip file '/sdcard/download/Magisk-v17.1(17100)'
Updating partition details...
...done.
I have tried the following:
made sure to have the latest zip from Magisk Manager
removed previous partial installs of Magisk by using the flashable remover
unrooted supersu (which I'm also no longer able to flash now, systemless or not, to reestablish root and try other methods--it sticks on the boot screen)
reflashed base crDroid
pulling Magisk 17.3 separately from Manager and using that to flash
I haven't found any resources on whether the 'insufficient partition size' problem is with TWRP or the Magisk flashing process so I haven't found anything to try specifically to fix that.
The last thing I have to try is making the flashable boot image and fastbooting it.

did you manage to fix this

Android 4.2 and 4.4 Mediatek bootloop after installing Magisk 18.1

Hello everybody.
I've read that 18.1 supports 4.2+ so I've tried to install in two MTK6589T devices I've. One running 4.2, the other running 4.4
CMW/TWRP gave an error mounting system, so I mounted system manually and it started flashing. Firstly it detected old root installed and disabled the old root. But when it tried to find the boot, installation was aborted because installator claims cannot find the boot on both phones.
Then I though, okay, lets reboot back to android, I will try to install a few days later, maybe its buggy now, but both phones cannot boot.
I can easily fix them by flashing rom again I guess, but I would like to know where's the issue and also post it for more people could face the same problem.
Any idea where's the problem/how to fix without rom reflashing? I've tried magisk uninstaller but after mounting system in recovery it is also giving error.
Thanks
UPDATE: For now, if no other solution is found, bootloop can be bypassed by dirty installing the rom again. But it has to be an easier workaround...
We know now that the problem is caused because of two factors merging:
1- Using Magisk.zip installer through custom recovery
2-In the case that the custom recovery CMW/TWRP installed in the phone is very old (for instance, CMW automade for MTK6589X or TWRP 2.5.0).
While installing, Magisk tries to send commands to the custom recovery that cant be understood by it, leaving the installation incomplete after some modifications in /system (read below recovery log).
Acording to the recovery, it seems that Magisk did some modifications without running correctly survival script - Adding addon.d survival script ("Unrecognized option '-Xnodex2oat'") and .zip installer is not designed to revert actions in this case.
Also, Magisk couldn't reach the boot modification step, so boot is not damaged, therefore workarounds for restoring boot won't work.
Using Magisk Unistaller.zip is also not possible as the uninstaller is mainly designed for boot backup restoration, and again, this is not the case.
Currently needed: Find what's wrong in system due to the incomplete Magisk installation to revert it back to the original state (before faulty magisk.zip installation).

I' also having the same problem. My Samsung J2 Prime stuck at logo after updating to 18.1. Any tips on how to fix it without resetting my phone? Thanks.
Update: Bootloop fixed. I used TWRP to restore boot image. I then update Magisk by flashing zip file from TWRP. Everything went back to normal. Hope this help.

If you have a backup of your boot image, you can just restore it using TWRP. But in case that you have no backup of boot image, you can try to get boot image from the internet and restoring using it. In my case, this is what I did.
1. Go to TWRP and then make backup of boot image of the faulty phone*. (Folder 1)
2. I used another J2 prime to create a boot image backup. (Folder 2)
3. Once that is done, copy and replace the files inside the Folder 2 into Folder 1.
4. Reboot to TWRP again then use that to restore the boot image on my stuck J2.
Tips: make backup in SD card so you can easily swap it in between the bad and good phone.
*This is to create a folder of the backup file. I did tried to directly copy and paste the backup boot image file from another good phone but TWRP didn't detect it. So this is the workaround that I come with. And it worked for me.
Thanks for your answer but I doubt your case is mine. Your device is much newer than mine and according to your comment, you've sucesfully installed previous version of Magisk without issues. This is not a problem while updating, as Magisk v. earlier than 18.1 was not compatible with android 4.2+. I think Magisk is not compatible with MT6589T even if they run 4.2 or 4.4.
I think that it cannot be a boot problem as TWRP/CWM displayed msg 'Boot cannot be found' while installing Magisk, so that I don't think boot was replaced or modified in any ways. Moreover, the bootloop is not in the boot loading, as phone can pass boot image without any problem, but it is stuck in android loading image. I'm thinking in some script or root modification that Magisk did before trying to unpack the boot, however I'm not that deep into the Magisk install to find the proper workaround.
I can restore boot backup and also I can take boot file from the original rom and flash, because in Mediatek-based devices, boot.img is inside de zip, but I dont think it will solve the problem. Anyhow I'll get back ASAP with the answer.
Any more ideas??
Nothing, boot/uboot restoration or flashing again just the boot won't fix the problem, so it's something that Magisk installator touch in /system or /data I guess, but what?

@trol_sg I'm gonna guess it's got to do with the absolutely ancient TWRP you're using. It just can't handle everything that the Magisk installation script is trying to do...
Your best bet (if Magisk will work at all on your device) is to patch the boot image with the Magisk Manager and then flash the patched image manually. There are new and shiny installation instructions available here: https://topjohnwu.github.io/Magisk/

Your best bet (if Magisk will work at all on your device) is to patch the boot image with the Magisk Manager and then flash the patched image manually. There are new and shiny installation instructions available here: https://topjohnwu.github.io/Magisk/

Thank you so much for your answer. So it's the recovery, but can't find newer ones, sadly. Too old phones I know, but just curious if I could make Magisk working on them, lol.
I was going into the boot modification manually right now, but in order to patch the boot I need manager installed first, and phone couldn't boot so I did dirty flash of the rom to be able to boot into it again.
Lets see what happens then. I'll be right back.
Anyhow, this is not a solution to fix the problem of bootloop that I am requesting help in case someone could face the same and did not make a backup of the phone and didn't want to make dirty re-flash. Any idea?
Update: After I did dirty flash of the rom, and now Jiayu g3s android 4.4 booted.
UPDATE: So, after patching manually boot and installing (using restore in TWRP 2.5 as image flash is not yet implemented AFAIK), phone booted and yes Magisk is working.
Magisk installation .zip through a very old recovery is making the bootloop. So that, a thing learnt now.
But, for other people facing this bootloop, can we do a research to find what magisk.zip did to the phones to leave them in bootloop? Maybe we can revert without rom flashing easily if we knew what's the issue...
Thanks in advance!
Doing a bit more tests I found that magisk.zip did something in /system so that it is left in bootloop, but still no idea why/whats causing that...
There are delay complete boot like 4 5 second in j7 prime. I didn't love this version
any more help?? up!!

Yes, I've read them before I made the post. I've also looked for a solution in some of the threads and using search, but couldn't find a way.

- volume up and then boot to TWRP
- copied magisk uninstall to phone memory
- installed magisk uninstall
- rebooted in fastboot/bootloader mode
- flashed original boot.img extracted from stock image zip file ("fastboot flash boot boot.img")
- rebooted to TWRP
- installed magisk 17.0 zip file
- rebooted to system, all OK!
Only problem is that I lost previous magisk configuration, but it's a snap to reconfigure it!

1) Do not update via Magisk Manager.
2) Do not update via TWRP using the zip you can download via Magisk Manager.
3) Uninstall Magisk using Magisk uninstaller (ZIP).
4) Boot to Android.
5) Reboot to TWRP
6) Install V17 ZIP via TWRP and boot to Android.
If you HAVE INSTALLED and got a bootloop:
1) Download the uninstaller ZIP.
2) Enter TWRP during the bootloop.
3) Uninstall using the uninstaller ZIP.
4) Boot to Android.
5) Download V17.
6) Reboot to TWRP and flash the V17.
7) Boot to Android it it should be working.

Hello, thanks
This method won't work in my case as in the step:
- installed magisk uninstall = gives error
Note 5 is much newer phone with a recent recovery TWRP that allows all Magisk.zips commands, but unluckyly not this case.
Also, this method is for wrong boot installation/damaged boot. In my case what Magisk damage is /system, not boot.
I wish it could be boot, because that is very easy to fix (flashing through fastboot/SP Flash tools in the case of MTK, recovering boot twrp "backup" even if you didn't make backup...) as you mentioned.
Hope someone have a great idea to revert system to origin, then we could post the solution for those who would like to install Magisk in 4.2+ old phones, and instead of doing boot flash manually, they try to flash magisk.zip and they got bootloop.
Main post updated with all thread information. Up!
Nothing?? Up!!

The only part of the Magisk installation that actually touches /system is if it installs the addon.d survival script. The log you posted earlier shows that it's trying to do this, for some reason, and failiing. I'd start looking there...
