Trouble Permanently Flashing TWRP - OnePlus 5 Questions & Answers

Hi,
I'm currently using the Skipsoft Android Toolkit to unlock flash TWRP onto my device. I've followed to first steps (install drivers, backup device and unlock bootloader) to the letter and everything went smooth.
Now the final part of installing TWRP is not going so well. Flashing the custom recovery works as expected and I end up in the TWRP menu. However, as soon as I reboot my phone and try to go back to the recovery via Advanced Reboot --> recovery, I end up in the default One Plus Recovery Menu. Now the tool mentioneds when this process fails, renaming the Recovery Restore Files is recommend to prevent the system from flashing the stock recovery on boot (what happens to my device). I follow this option in which I end up back in TWRP, flash a zip named 'permanent-recovery.zip' (while read only mode is turned off in TWRP) and reboot my device. Still when I use Advanced Reboot to open recovery, I end up once again in the Stock Recovery.
Is there anyone who could tell me where I am going wrong and how to solve this issue?
Thanks in advance

The basic "mechanics" of what happens seems to still be as follows:
As your phone is delivered with Stock OS, it has these two files installed:
Code:
/system/recovery-from-boot.p
/system/etc/install-recovery.sh
I know from looking at mine when I got it that it had /system/recovery-from-boot.p installed. If it's there, it is run when it runs at boot.
To stop that behavior you have to get rid of those files before you reboot the first time from recovery or else recovery will be replaced with the stock image. I'm aware that supposedly the custom recovery supposedly renames either one or the other or both of these but am not convinced it does this or whether installing root (either Magisk or SuperSU) does it. Either way, since you're stuck with the problem, either from file-manager in TWRP if that's all you can boot to, you need to rename /system/recovery-from-boot.p to something like /system/recovery-from-boot.p.orig and maybe the other one /system/etc/install-recovery.sh to /system/etc/install-recovery.sh.orig as well.
Once even the .p file is gone, it's not going to rewrite recovery. You must, of course, be rooted before you can touch those files although if you can sideboot TWRP, it seems like you are rooted while it is booted and "should" have access to system files if you can mount system rw.
I've fixed it this way on other phones. On this one, installing the "official" TWRP and Magisk did it. When I booted into /system after installing Magisk, I looked for the .p file and found it renamed to /system/recovery-from-boot.bak.
I found a link for a Samsung s8 for the same purpose. It's probably identical. http://www.teamandroid.com/2017/04/25/install-galaxy-s8-twrp-310-recovery/3/

I looked into those two files while in TWRP and noticed I only had the recovery-from-boot.p file. This was already in fact renamed to recovery-from-boot.p.bak. I renamed it once again (just to be sure) and after flashing the .zip I mentioned earlier, the TWRP did not last another reboot...
Can I after flashing TWRP again, immediately flash Magsik? I intended to hold off rooting because the rom I was going to install has Magisk build into it. I don't want to create a conflict when flashing later on. Is this going to be an issue?
@hachamacha I've reread your post and wondering if rooting my device is even going to make a difference right now? Since I'm already able to rename files in the system directory, would it even make a difference?

To me, it doesn't sound like a conflict to re-install Magisk over itself in FOS and see if that helps. The real "action" that counts is all about whether you've already booted into the OS after installing TWRP and then how you go about getting rid of the .p file without doing a regular reboot via the OS. Even installing the FOS ROM should get rid of the .p file (rename it), so something else is going on. I'll look around some more and update this if I can.
By the way: Depending upon how exactly you got from TWRP to the OS the first time, it could already have rewritten the stock recovery by the time you noticed *.p file renamed to *.bak.
OK: I recalled how I did this without a problem: I wrote instructions somewhere but have no idea where. This is what I think I did:
1) fastboot flash recovery recovery.img (custom/TWRP)
2) fastboot boot recovery.img (so force it to load recovery without a traditional reboot).
3) install ROM from that point and after done just hit the reboot button (or install Magisk from that point and hit reboot).

Just saw this note:
Anytime you're in TWRP, you're automatically "rooted" for the time you're there. It's integral to TWRP having permissions to do anything like install etc. If you just "loaded" TWRP (as in fastboot boot twrprecovery.img) then you'd be rooted, but when you rebooted to the system, you'd be unrooted. While you were in TWRP, in theory you could make file system changes to the /system partition (a) if TWRP lets you mount it rw which I think that first swipe does and b) if you can see the correct files in it's file manager.
So it "seems" like those file changes should be actual file changes to the correct place. Keep in mind that while booted in TWRP, TWRP may have it's own ./system/ that has nothing to do with the OS's ./system folder, so you've got to be able to mount the OS's ./system. TWRP's ./system is already fine and of no importance for this. I can boot mine into TWRP and look around to try to clear this up, but it might not be crystal clear to me either.
The output of a TWRP terminal emulator "mount" command might be of use but it will be messy. Maybe if you can do this in emulator from TWRP:
# mount | grep system, and look at that output, perhaps put it in this post, it'd be of help. The mounted rw ./system we need is going to be the same one you'd see from adb shell or terminal emulator while booted from the OS. My guess is that the one we don't want from TWRP's perspective will be mounted as /system (params...) and that the the OS's system either will not yet be mounted and you'll have to go to mounts and mount it and then look at the output of the mount cmd again to figure out what it was mounted as. Sorry about how complicated this explanation has become. Anyway: The ./system that corresponds to the OS is the only one we care about.
There's no easy way to explain it so I'll leave it hidden to spare anyone having to look at it:
I just booted into TWRP and used terminal emulator and file manager to explore:
findings: While in TWRP, using terminal emulator to do a
$ df and then a $ mount command shows no ./system mounted specifically. // maybe not a surprise.
// TWRP just mounts it's root / file system and there is a /system folder, just not a specific mount point for it.
// TWRP does not auto mount the OS's ./system partition by default. It depends what you're going to do there.
Without going into "mounts" and clicking on /system, it won't even try to mount /system for the OS.
If you can get that mount to work in read/write mode, then you should be able to see the ./system mount using terminal emulator as such.
$ mount | grep -i system (and look specifically for ./system on the right side of whatever appears).
In theory you should be able to make changes to the OS's /system partition now. When you're done, unmount it. (I'm assuming all this works from TWRP, a dodgy assumption)
At this point: I'm just trying to figure out how TWRP does things like installs OS zips to the /system & /data partitions which it is clearly successfully able to do. It could do it without mounting anything because it could use the linux dd command, which just writes to the /dev name. OR: It could mount /system and use it. I'm not sure which.

I followed these steps and I managed to install FreedomOS without any issues. My phone booted normally and after a few complimentary steps I booted back into recovery and... TWRP! No more stock recovery. Thanks a lot!
Just one more question: TWRP currently asks whether it is allowed to install itself as a system app. Now I assume it is already a system app, but I'm not expert at this so I can't say for sure. Would you recommend me to install TWRP as a system app?

Great! Glad that worked. I guess it's all about how that first boot to the OS occurs.
Anyway: Your question, I'm assuming is about TWRP "Manager" the app? If so, yes, it should be a system app. The thing is that "Official TWRP Manager" doesn't really do much of use that you wouldn't just as soon do from fastboot, so it's not critical and nothing other than TWRP manager will "not work" regardless of what you designate it. All saying it's a system app does is puts a slot for it in Magisks "root table".
Cheers.

alt-w missing

I hope someone can help. Originally, when I downloaded Hero beta4 it came with a recovery file. Since I didnt know where it went, I did not adb it over. Now, everytime I wipe (i am now running rosie), it locks up at the Android screen and endless boots. I am sure it is because I am missing my recovery image. I presume I can use any update.zip and rename it recovery.something. My questions are
1. what is this recovery file named?
2. Where does it go? I have app_s installed to my ext2 partition for rosie.
If you boot up without holding down the home key (a normal boot in other words) the system doesn't touch your recovery partition. So having a damaged recovery is likely not the cause of your looping. If you want to install a recovery.img you can just grab it out of a full updater or as a separate file.
Thanks, but you said something interesting. You said recovery partition. Where is that? And would I use ADB to push the recovery file over to where ever?
it only boot-loops when i wipe. If I update, things go smoothly. Until I wipe again. Seems like i am missing the recovery image (since it came with the download but I never moved it).
Thanks jashsu for your prompt response.

I don't think it's the recovery partition. I get kinda the same with tehseano's Hero theme 1.1. When I wipe before applying the update, I get problems with home app. And after, I get a bootloop..

Problems Rooting Nexus S 4G with Mac

OK, so I just got my Nexus S4G two days ago, and I'm ready to root. My phone out of the box has 2.3.4 on it.
I follow this tutorial: http://www.droidfiles.us/nexus-s-4g/root-nexus-s-4g/ the link to which was provided by a good XDA'er. I get the bootloader unlocked and install CWR (recovery-clockwork-3.0.2.4-crespo.img) and that goes fine.
That's when things stop going fine.
First, I try to create a Nandroid backup, and that process seemingly completes fine until i note that the process says it couldn't mount /data. I don't worry about it.
So, I go to Mounts and Storage to prepare to push SuperUser.zip and I tell CWR to "Mount USB Storage" and I wait as directed, but the USB storage never mounts. I try mounting USB Storage and mounting /sdcard, neither of which work, so I can't push SuperUser.zip.
Figuring I did something wrong, I decide to restore from Nandroid, only to have CWR tell me that the MD5 checksum is incorrect and now I have no clean, base Nandroid to restore to.
Then I do some digging, and discover that there's a new CWR for the NS4G at Koush's site and I download the file (recovery-clockwork-3.1.0.0-crespo4g.img) from there, push it to my phone using fastboot's recovery command and start it up.
It doesn't work.
Clicking any of the options (like mounting partitions, or restarting/powering down the phone) causes the screen to go blank and just display the CWR logo in the middle of the screen. The only solution to get out of those loops is to pull battery and restart.
So, now, I'm wondering what to do.
I go back into fastboot, relock the bootloader and I now wait for a reliable root method to root a 2.3.4 NS4G on a Mac.
My questions are:
Where can I get a stock ROM to completely start over from scratch and even remove the recovery I've installed <-- found a base ROM here: http://forum.xda-developers.com/showthread.php?t=1078213
Is there a fully reliable way to root the NS4G on a Mac, and if so how? (I've looked at this thread: http://forum.xda-developers.com/showthread.php?t=878446 and it looks problematic as well).
Look in the dev section, stickies at top, the one talking about ns4g cdma. You have the su zip already. Put the cwm 3024 img file in the same directory as fastboot. You won't use adb. Boot into bootloader and do the fastboot command to unlock. Phone is wiped. Boot into phone normally and log in with gmail. On the phone, mount the device as usb so you can just copy the su zip to the root of the sd card.unmount phone on the Mac side then the phone side. Boot phone into bootloader. Do the command to fastboot the cwm into the phone again. Once finished, choose recovery on bootloader. It will boot into cwm. Choose install zip from card. Choose pick zip. Install su. Reboot into normal phone. Download busybox and a file manager you like that can handle root. With file manager, go to /system/etc and look for the sh file mentioned in the guide and add .old to the end of the file. If su pops up asking for permissions then you know everything is working. Boot into bootloader again. Install cwm again then choose recovery again. Once in cwm do wipe of caches and factory reset and dalvik. Go back and do backup with nandroid. Boot into normal phone. Sign into google again. Update profile and prl them you should be set. Pretty much that's what I did and it worked the first time around.

I'm going to give your method a try. Thank you for your rapid response...
I see the subtle change you suggested: simply rebooting after unlocking and pushing recovery, and moving SU to the device via USB. Wish I'd thought of that.
(I'm still concerned about the Nandroid issue I reported. But I'll have to avoid any new ROMs for the time being, until I can get an answer for my Nandroid problem...)
My first nandroid choked. After root and final recovery install, I cleared all the caches it was *****ing about the first time, went in normally to make sure everything was okay, then went back and nandroid and no errors the second time. I probably will just stay with rooted stock but I would not flash other stuff until the dust settles and many of the bugs are worked out of the roms and kernels before jumping in.

If cwm mount won't work then boot into the phone normally and copy over the file like usual is the only other quick and easy way to do it that I could think of at the moment the snafu happened. Yeah the way I did it might not have been the most efficient way but it got me past the hurdle that cwm made quickly. In the end, the result is the same so no big deal.
I don't know if cwm backs up wimax keys so I did it manually. There's a post on how to do it, I don't know if it's in this section. It might be dev?

Factory Reset wiped out the internal SD card! I thought it's not meant to happen?!

This is the first time I'm using a device that doesn't have an external SD card, but I've all along understood that the internal SD card does not get wiped when you do a factory reset, and I'm sure I read that again on another thread just the other day.
My N7 is rooted using Wug's toolkit, with CM10.2 and Bulletproof kernel.
Yesterday I decided to do a factory reset (under Settings, Backup & Reset, Factory Data Reset), but after I did it, all the stuff I had on the internal SD was gone, including my backup files, the ROMs I had transferred there, etc.
Surely this is not meant to be the case, is it??
internal sdcard used to be a different partition.
Now it is just a directory in your /data and the "sdcard" is an emulated sdcard.
I know stock ROM and stock recovery wipes /data and everything in it including the virtual sdcard.
TWRP recovery will only remove the /data user stuff, leaving the virtual sdcard alone.
Which recovery are you running?

Thanks for that! (Thanks coming your way). Well, better to know now than later! The down side is that I lost my CWM backups and my Titanium Backup files, but the good thing is that I think I have a TWRP backup that's on my computer.
I'm using TWRP, but not really liking it, cos I cannot boot into recovery from the phone and have to keep relying on the Wug Toolkit. I've just downloaded CWM and will be switching to that.
So the moral of this story is that if we are to do a factory reset, we should do it via recovery, correct? I'm presuming CWM will also leave the virtual sd card alone, yeah?
Oh one more thing, I think I lost root after the factory reset!!
I checked my All Apps and SuperSu wasn't there anymore. Just rooted it again using Wug kit.

I am not sure what issue you are having with TWRP, but you can flash it to the recovery partition and boot to it automatically. If that's the only reason you don't like it, I'd work on fixing the install rather than jumping to another recovery.

I would probably do it from recovery. I don't know what CWM does on this platform as I've only used it on other platforms.
What do you mean you can't boot into recovery with twrp? I'm using twrp and have no problem booting into recovery.

When I try to boot into recovery, it ends up showing a dead android with the red triangle "!" sign. I remember doing some searches and it seemed like this was normal. I remember the reason was that the N7 would always rewrite the recovery or something. From your responses, I'm guessing it's not normal?
The only way I could get into recovery was using the Wug toolkit using USB debugging/ADB, which really sucked, cos if it bootlooped and I can't get into the system to turn on USB debugging, then I'm not sure what I would do (though I read there's some way around it or something). I had never encountered any such thing with all my many other devices which all run CWM.
So what's up with all that?

This will work fine. If you have no aversion to installing apps, Rom Toolbox Lite gives you power widgets you can put on your desktop then go to recovery with one touch. I use Quick Boot PRO, although the free version of that all may do recovery also. One might work for you until you want to play with mods.

That is stock recovery.
You need to get rid of /system/etc/install-recovery.sh
You can get rid of it by hand, or just install SuperSU from TWRP. Then flash TWRP to the recovery partition.
Thank you everyone for your input!
I'm happily back on CWM right now. If I revert back to TWRP next time at least I'll know what to do!

OK let me get something straight.
Obviously, the factory resetting that wiped out all internal storage (the original point of the thread) has nothing to do with TWRP, and I never said it did. On this point though, I'm surprised that it doesn't seem to be more well known that a factory reset would do wipe out all your data (did several searches and only found 'confirmations' that your internal SD data would be left untouched), though I'm glad that I know it now.
The suggestions on different ways to boot into recovery were helpful, though I believe that I would still have encountered the dead android, or would I not have?
What's certainly still not clear to me though is regarding the problem of not being able to boot into recovery and getting the dead android with the exclamation/triangle. After the first few replies, I expected to hear that this was NOT meant to be the case and that I did something wrong in the process or whatever.
However, what I seemed to get was that this is the expected behavior, and what I needed to have done was to "get rid of /system/etc/install-recovery.sh".
So let me ask these questions for clarification:
1. Is the dead android normal, given what I did/didn't do?
2. Is deleting /system/etc/install-recovery.sh part of the process of installing TWRP in order to be able to boot into recovery?
3. Would I also need to get rid of /system/etc/install-recovery.sh if using CWM?
(so far it doesn't seem to. After installing CWM I'm not getting the dead android and I didn't delete the install-recovery.sh).
Thanks. And just to be clear, I hope no one takes it the wrong way that I'm bashing TWRP or anything, because I"m not. Just been a long time user of CWM and this is the first time using TWRP and encountering the dead android.

Dead android = stock recovery, so normal there.
When you flash a custom recovery on a stock ROM, there is a file, /system/etc/install-recovery.sh, or I actually prefer just renaming /system/recovery-from-boot.p, which will automatically verify your recovery image and restore it to stock if it doesn't match. So you must always remove this file, or the ROM will restore the stock recovery on boot.
TWRP makes it easy to remove either file by mounting /system in read-write mode and using its built-in file manager to remove it. You can do the same in CWM using adb.
As for point 3, yes, try to reboot into recovery again. If you didn't remove (either file), you'll find stock recovery again.
Thanks, Khaytsus. I booted into recovery (long press power button, reboot menu, recovery), and it booted straight into CWM, like it always has with my other devices. (And to confirm, I have not even looked for the install-recovery.sh file, let alone removed or renamed it.)
So far it seems to me that TWRP requires removal of install-recovery.sh, whereas CWM does not, but this doesn't seem to be what you guys are telling me is supposed to be the case.

It really depends on what ordering you do your actions in.
/system/etc/install-recovery.sh doesn't exist on a stock factory shipped system.
It only gets put in place after you install an OTA. If you do all your upgrades using the factory images, you'll never encounter it.
What it does is during your boot process, it will check to see if your recovery is different than what it expects (ie stock). If so, it will install stock recovery by taking the stock kernel and patching it.
If any of the following are true, it will not overwrite your recovery:
/system/etc/install-recovery.sh is missing (or modified to not run as the original file)
/system/recovery-from-boot.p is missing
you are not running the stock kernel
The most common way for install-recovery.sh to be missing is you always used factory images.
The most common way for install-recovery.sh to be modified to not do the original function is if you installed SuperSU. It will overwrite install-recovery.sh with its own.
So in all the back and forth, it is quite possible you got rid of install-recovery.sh or had it modified simply by installing root.
If you then subsequently installed custom recovery, it would stay in place.
Previously you were installing TWRP and flashing it onto the tablet, but upon booting into android, install-recovery.sh realized it wasn't stock recovery, and overwrote TWRP with stock recovery.
That is why whenever you rebooted, you got fallen android (which is stock recovery)
If the way you installed cwm is to use "fastboot flash recovery cwm.img" then the only reason it is around is because something else you did got rid of or modified install-recovery.sh. cwm would be no more immune to install-recovery.sh than twrp was.

Oh one more thing, I think I lost root after the factory reset!!
I checked my All Apps and SuperSu wasn't there anymore. Just rooted it again using Wug kit.

Just to clarify, you didn't lose root. You just lost the supersu app, a root permission manager, because it was installed to your /data partition. The su binary was still in /system, all you would have had to do was install supersu from the market.
I'm not sure what else you were expecting from a "factory reset"

Did you read the thread? He explained his reason for expectation quite well.
I just started up on a Nexus 4, and was also surprised to see this. Coming from a Galaxy S2, the "sdcard" being left intact was pretty convenient when flashing from ROM to ROM. Albeit, leading to some messiness. When did Nexus change to this behavior?

Depending on which level you are looking at, it didn't really change the behavior, but rather how your data is organized.
Factory reset has always wiped out /data.
On older devices, they put the /sdcard in a separate partition and formatted fat32.
These are the ones that were surviving a factory reset.
On newer devices, the internal /sdcard is starting to migrate onto a directory in /data and the "sdard" you see is "virtual". Since it is on /data, when you wipe data, the virtual sdcard is also wiped.
Some recoveries try to simulate the previous behavior by doing a "rm" of every directory except the virtual sdard when you choose to wipe, instead of the erase/format that Android is doing.
The advantage of keeping the sdcard as a directory under /data is you don't need to decide how much space to split between the sdcard and your /data. Also permissions on files are more flexible being in an ext4 filesystem. Finally since everything is emulated and accessed via MTP, you don't need to unmount the filesystem, so your PC can access it.
There are also cons with this approach, but that is what Google is going with.

Create Stock Recovery.img from FTF File

Hi, I am in the process of preparing for upgrading from 7.0 to 7.1.1
I know I need to replace the Custom Kernel with the Stock Kernel. And I have to replace TWRP with Stock Recovery.
Can anybody tell me, which file inside the FTF is the stock recovery? I already found the kernel. Need help to find the stock recovery, thank you!

We don't have one which is why we have to use TWRP.
So my only way is to flash via Flashtool without wipe?

Do that then mod your own kernel. [How To] make your own XPERIA DRM-fix kernel.
And flash a TWRP.img to the recovery partition.
fotakernel.sin reside's where we flash twrp on stock. you do not need to flash it to upgrade, contrary you can exclude it in flashtool and keep twrp between updates.

this is real knowledge, thanks! so just to be sure, this is what i will do in flashtool:
1) wipe: nothing selected
2) exclude: fotakernel.sin selected
can anybody confirm this is correct?
then after this, i will flash a custom kernel via fastboot and magisk via twrp.
one question regarding magisk: will it be deleted during the flashtool update?
So I ran into a problem...
The Upgrade to 7.1.1 via flashtool was smooth. Then, i flashed twrp via fastboot as usual. When I tried to enter twrp, i get a password prompt to decrypt the phone. So i don't know which password i need to type in. I tried the unlock PIN, doesnt work. Any suggestions?

To get round that you need to run the following commands...
Code:
fastboot format userdata
fastboot format cache
...so you'll need to backup all your data first.

Ok, so I decided to keep my data and don't install twrp. Now I got another issue, is it possible to install Magisk without TWRP? I already got my kernel using my ta backup according to the instructions a few posts above, which really works great.

I thought you excluded fotakernel so you did not have to flash twrp again. Oh well anyway you can use twrp to flash zips just fine although /data is encrypted, most flash zips do not write to /data anyway some like supersu use /cache (which is not encrypted contrary to the info above) to get around encryption at next boot. And like magisk also patch the boot.img live on your phone, some write to /system which is not encrypted either, I never seen a flash zip that did write to /data. Only backup/browsing/etc on /data is affected.
So when presented with the password screen in twrp just press cancel and make sure the zip you want to flash is located on the external sd card (do not encrypt this in phone settings, your card will be unreadable from pcs to) then choose flash zip and choose the external sdcard to pick the zip from and flash magisk or whatever. You need to run your kernel through ta poc or rootkernel first and disable dm verity and sony ric. (you write you did this so just install twrp and flash away) Do not wipe cache before rebooting just in case magisk uses this in a similar way to supersu (I have no idea)
Also if you do the above fastboot format commands suggested in post#8 without disabling 'forceencrypt' for /data (fstab in the kernel image or with a tool) the phone will encrypt itself again as soon as you turn it on.
If forceencrypt is disabled the same can be achieved (clearing encryption) with a factory reset btw.
So if you did not bump into the password in twrp before you likely did a factory reset with a kernel with encryption disabled. Then, maybe after updating you rebooted stock and the phone encrypted itself again, then now you can not access /data in twrp. Thats also because we have no version of it that supports encryption on the X-compact though. Again do not worry, I have not meet a zip I could not flash, supersu, magisk, etc because they do not access /data anyway.

Yes, after the first upgrade attempt, i let twrp untouched. then when entering twrp, i didnt have a password, so i skipped it. i couldn't find the sd card in the file browser, and after i hit reboot in twrp the phone restarted and got stuck in boot.
So I flashed again, this time deleting twrp. the initial boot up went fine. Then i flashed twrp again and once again, without having a password, i just skipped the password prompt. still couldnt find the sd card, and i rebooted out of twrp. and the phone got stuck again.
after 2-3 trials, i figured out that everytime i rebooted out of twrp, the phone gets stuck during boot. even after turning it off and on, so a reflash was needed.
now i have given up using twrp, so i have an unrooted phone with an unlocked bootloader. which does not allow me to use android pay. i think to solve my problem is:
1) i need to know which twrp version really works, i have tried
this version
and this version
both cause a boot failure for me
2) i need to find the sd card location in the twrp file browser (all the folders show empty for me)
if nothing works, i guess i need to wipe my phone, but that's what i would like to avoid. thanks for your help guys!

The 2. issue with the sdcard is easy. After pressing 'install' button in twrp at the bottom left press the "select storage' button, a small window will pop up then select the 'micro sdcard' and press 'ok", you should see your files now.
The 1. ssue is really odd! I use the second twrp you posted, for some wierd reason the first one does not boot for me (twrp does not start). But I talked with another guy for him it was the other way around. It was really strange. I think most can use both though without problems
There is one more twrp 3.1 from bambamx, but I really do not get this, twrp boots from its own partition with its own kernel. They should be separated unless twrp does something to system ofcause which it very well shouldn't unless you ask it to, deleting a important file or flashing something. I have never heard of this sorry. One thing is certain our device sure could use a stable nougat encryption compatible twrp!
I will let you know if I find something, you can try the last available version, I have no idea if it will exhibit the same strange behaviour. But maybe its worth a shot although it seems something else is at play.
A couple of stupid questions sorry; You disabled dm verity and sony ric in ta poc right, and it does not happen if you boot your phone normal a couple of times.
Edit: sorry Mr. Sandman had not left so I did not read properly here from the morning. I will edit my post to actually answer as best as I can lol.
Just to let you know:
1. You do not need to install TWRP to use it! You can just do
Code:
fastboot boot <TWRP image>
to run TWRP on the phone (instead of
Code:
fastboot flash boot <TWRP image>
). The only drawback of this method is that you will always need a computer to enter TWRP. Btw. with this method you can also try out a custom kernel image before flashing it.
2. You do not need write access to /data partition to install Magisk. It was explained in another thread that Magisk can use /cache temporary when access to /data is not available. It will write to /data on first boot instead.
3. While using TWRP you can use adb to transfer files onto the phone, so you don't need to have them ready on the internal storage.

I did, but the SD card can't be selected, and the size shows as 0kb. I did a workaround though: i formatted a spare sd card and copied magisk on it. it was instantly recognized and selectable.

GREAT advice! I launched TWRP from ADB and successfully flashed Magisk using ADB sideload. Thanks, my phone is rooted again!

Freezes on Google screen after attempted SU Install from TWRP

Ok I am sure I did this before without any problem, but this time, through TWRP on the NRTK, I installed Magisk, no problems, and then went back to install the SU with the zip file in TWRP again and then on the reboot it freezes on the Google startup screen.
I didnt even want to install the SU zip, but when I ran SU after Magisk installed after reboot, SU gave an error, so I decided to install SU from TWRP.
Did I do something wrong there, so I dont repeat the same error next time?
And how do I get out of this locked state?
I've tried wiping all cache to factory reset without deleting internal storage data... I am hoping I dont have to delete and wipe everything and start all over. I did not have a chance to eve install TiB yet.

Flash the stock boot.img from the image/rom you were using before this and reboot. You will have to re-root (properly) afterwards, but your phone should boot up. If you use Magisk, you don't need SU, and vice versa. Use only one method to root.

Hmmm ya I prob should have posted that SU error message instead of what I did, douche move.
But how do I flash the boot.img... I have an original copy of it on my PC... can I somehow while in TWRP on the phone connect to my PC via cable and run commands from my PC in CMD and execute that old boot.img flash? Or is there a location in the stock Nexus already I can use? Because there is no file in the root drive after I did the soft wipe.
P.S. Everything I have done so far has not deleted my whole storage, yet.... not sure if that is necessary at this point bec it seems reflashing the boot.img wipes absolutely everything again? If I have to it is what it is... just painful when this happens before I could get TiB running... unless my Nandroid backup file I have will restore and work after I do this?

While in TWRP you have MTP (file transfer) so you can add files to your device. Transfer the boot.img over to your device via MTP and then use TWRP to flash. Just be sure to select flash IMAGE rather than ZIP. Lesson here is when you get back up and running, install fastboot/adb and make sure it is working well and communicating with your PC. Then you can learn how to use it. This would take literally 5 seconds to flash via fastboot (device in bootloader mode).

NO, flashing boot.img will not delete any of your files. It will only write to the boot partition. If using fastboot the command is fastboot flash boot boot.img

Yep I actually had those platform files already, and yes the MTP was active there, I just never tried that before so didnt know it was even a possibility or the right way.
So I tried via flashing my very old boot.img and also the one from
https://forum.xda-developers.com/nexus-6p/general/stock-modified-boot-img-regular-root-t3306684
via TWRP "Install" via image install (not zip) and to the "boot partition"
and no change, same stuck on Google logo screen.
I tried the fastboot command from CMD and it says
< waiting for any device >
and doesnt do anything. I had it on the default TWRP menu screen.... I waited over 20 min although I know it shouldnt take near that long, just in case.
My bootloader is unlocked BTW, I dont want to assume anything here.
You need help getting the latest fastboot/adb binaries working on your PC. So many tutorials on how to do this. Ugh.

Which OS security patch were you running? Flash the system (to the system partition in TWRP) and boot images (again) from the 6P factory image of the same name:

See if this helps.

Not sure what you mean... I JUST did all that when I redid my phone completely back to factory etc etc.... just few weeks ago and then again on my new replacement. But just to be sure, I downloaded all those files again today and it didnt make any difference.
Still stuck on the
< waiting for any device >
I have to be missing some other step or something else is wrong here.
FYI not sure if this matters but when phone boots to recovery there's a red error message
"Unable to mount storage"
but it loads to TWRP fine anyways.

Yep thats what I been doing.....
So the CMD command still doesnt work, which I think is weird in itself... and when I try to install from recovery, it goes through the whole process, both boot.img and system.img, but then it freezes on the Google logo again, so no change.
Sorry I am not sure what security patch, I just got this used from eBay, and one thing, not sure if this means anything, it says its a beta version or something and that message came up all the time when I rebooted when the phone was working.
Do I need to suck it up and redo the whole phone again........ :/
