TWRP and rom install - Google Pixel 2 Questions & Answers

I've been reading about bricks.
TWRP install is:
Get adb/fastboot working
Boot the img
From TWRP install zip
Rom install is just like any other TWRP rom install?

I just rooted mine over the weekend since taking a break from spending way too much time on that stuff since I had an HTC 10 ... To answer your last question, I think it differs a bit (at least from what I remember) in that you have to fastboot flash the patched boot from Magisk.
This worked for me, but for some reason, it look me half a dozen tries to obtain root, no clue why, but it was frustrating. And I swear the unrooted device was hella faster. Just installed the full iteration of the stock image per that thread.
+ Magisk install
adb push boot.img /sdcard/Download
adb pull /sdcard/Download/magisk_patched.img
fastboot flash boot magisk_patched.img
fastboot reboot

Could you tell me your cid? Bootloader unlock is arguing with me....

Need help rooting Nexus 5

hey guys, I need help rooting my Nexus 5 running the latest version of Android, 6.0.1
I can't seem to find a method which sounds safe enough ..
I'm no newcomer to rooting as I have done it with many other devices but this is my first time trying it on a device running marshmallow
You could try what I did successfully with SuperSU 2.62 - I'm on MM 6.0.1 and was completely stock. I believe newer SuperSU versions are amendments/improvements to the install method rather than to the SuperSU binary functions.
Copy SuperSU 2.65 (brand new today) to your device, boot temporarily into TWRP ("fastboot boot twrp.img" rather than "fastboot flash recovery twrp.img" which will permanently overwrite the stock recovery - make sure to get the right version for your N5), then in TWRP install SuperSU and reboot. You retain stock recovery (because TWRP lasts just for that session) and you can use SuperSU's full unroot function when the next OTA rolls out, install it, and then reroot.

Although Chainfire does stress that this is experimental, I've had no problems with it at all, like most other people. Still, I'll repeat his warning that everybody roots at his/her own risk. You'd have to be really unlucky, careless or stupendously incompetent to do unrecoverable damage...

i am not currently running twrp.. how do i flash it from recovery ?
Download into fastboot mode and you can use fastboot commands to flash TWRP on a permanent or temporary basis to the phone, boot into twrp, flash supersu, and reboot.
I provided the link to TWRP (rename it to twrp.img after downloading) and the command you need ("fastboot boot twrp.img" without inverted commas). Which piece isn't clear?
Edit: you aren't flashing TWRP from recovery. TWRP is the recovery. All you're doing is temporarily installing TWRP to allow you to install SuperSU. I obviously have to work on my communications skills...
Edit #2: To be sure that my message is clear, the temporary TWRP installation is done via Fastboot on the PC, not within TWRP. When you've temporarily installed TWRP, which will cause your N5 to display the TWRP screen, install the SuperSU on your device (put it somewhere where you can easily find it, like Downloads), then reboot. Job done.
Questions...?
i just tried flashing and i run into an error
FAILED(remote:image is not a boot image)
i have run into this error before but i cant recall how i fixed it . any suggestions?
I have to ask - sorry...
"I'm no newcomer to rooting as I have done it with many other devices but this is my first time trying it on a device running marshmallow"
Marshmallow is admittedly slightly different from previous versions, but not show-stoppingly. I've given you the best root instructions as clearly as I can with pointers to a Marshmallow-specific root.
What exactly have you done to invoke the "FAILED" message? Did you follow my instructions to the letter?
(Edit: I do feel your pain. Sorry for appearing frustrated, since I was a total noob not long ago and am still very far short of the many people here who know the technicalities of Android infinitely better than I do, but you really have to follow the advice and provide better information if you want people to have the patience to help you.)

Are you running a Windows PC? Is the phone detected properly in fastboot mode? What command are you typing in?
yes I am running a windows pc, device is detected and I have used both :fastboot flash recovery twrp.img and fastboot boot recovery twrp.img
Now I see two mistakes in your commands, maybe mistypes.
:fastboot flash recovery twrp.img - this would install TWRP permanently in the recovery partition - if you lose the colon at the beginning.
fastboot boot recovery twrp.img - no "recovery" - just fastboot boot twrp.img - this will boot TWRP temporarily.
And have you downloaded TWRP, renamed it for ease of typing to "twrp.img" and put it in the fastboot directory? If Fastboot doesn't find twrp.img in its directory this would cause an error.
oh kk .my bad .. thanks
So you've had 15 minutes. It must be done by now, right?

What is the best version of TWRP ro install on nexus 5 cata 6.0.1?
I suggest 2.8.7.0.
Just out of curiosity, why not 2.8.7.1? I think I read recently that someone had had some sort of problem with it, but I've been using it with no problems at all.

Installed TWRP to Boot, want to boot myself in the a**.

Own the OPP6; Rooted, on OxygenOS 5.18.
Went to install the newest TWRP (was going to install XXX no limits), when asked where to install it to, accidentally, without thinking, hit install to Boot.
Problems.
I can get into fastboot, the PC sees the phone in fastboot.
Have tried to flash a recovery image and similar, got an error saying: FAILED (remote: (recovery_b) No such partition).
Just want to get the phone booting again, wipe the whole thing start over, from fastboot.
Any help appreciated.

What you should have done was fastboot boot twrp.img. which would start twrp, then you could have used the installer in to install twrp on phone. After that you would have to installed stock or custom kernel.

That is exactly what I wanted to do.
I could get into TWRP, but I couldn't see the phone on the PC and couldn't move files (ROM) to the phone (although fastboot was working and I could see the device using adb) but I couldn't figure out how to have TWRP look for or find the ROM on the PC.
There's no recovery partition on A/B phones remember.

Thanks for that. and that explains a few things and explains why when I installed TWRP, I didn't see the recovery option. Doesn't pardon my hitting install to Boot.
Just thought of another Q, if there is no recovery partition, where is the OEM recovery stored? (I figured the lack of a recovery partition is why TWRP gets overwritten if installed without a custom ROM)
I did a quick read on that, it seems really interesting and may be of some use as soon as I learn more.
I've got so much to learn about this. I keep meaning to take time to begin, but stuff comes up and boom more changes.
I've got to do more reading to take advantage of that.
@MrSteelX mentioned that I could have used TWRP to install a ROM from the PC.
Is this what is referred to as "sideloading". I've been looking for some info on this and haven't really come across much that is any good.
Are there any available guides that anyone can point to so I can learn about using TWRP that way?

In twrp, you go to advance/sideload. Twrp then waits for adb sideload to push file to phone then auto flashes file.
In your case, you would sideload rom to flash and have been go to go.

I will give this a try. After I learn a little more about the A/B partitions & recovery on this phone, I want to try one on the custom ROMs.

Thanks for the link/guide. I had been trying an iteration of this (and the guide) but after reading your link, it too explains some things. I was trying to restore a Stock ROM from fastboot according to your link:
Things are changing with the advent of project treble. OnePlus will no longer release ROMs flashable via recovery (either stock or twrp) because is no more needed. The updates will be done on the slot not used for example if you are using slot a the update will be installed on slot b and the slot b will be set as default. If you brick and you are in bootloop how you can restore the rom? You can't with Stock ROM you have, because the zip can be only installed via Update Engine, so what can you do? Flash a stock rom via fastboot. I have extracted all images from the stock zip and i have made a new zip with the Fastboot ROM with a flash-all.bat included. This will work only if your bootloader is unlcoked. This will erase all your data and will wipe
I download and was trying to use the stock ROMs, I didn't see any bats, and now I know why.
Lots more reading to do. I love doing playing with this stuff, but trying to learn & keep up with things burns time, which most days I don't have.
This is the longest I've ever been on a stock OS (6 weeks? got the phone right after its release) although it's rooted (can never leave things completely alone).

"recovery" (what's left of it... wipe and mostly nothing else) is inside the boot partition. TWRP on those devices is installed into the boot partition (NOT overwriting the boot partition, but into the "ramdisk", a part of the kernel where OEM recovery resides and where TWRP, Magisk, Xposed and all the mods do their stuff on the kernel. On a phone with A/B partitions, you have to fastboot BOOT twrp, and then you have to flash the installer zip, you should never ever flash the image to any partition since there isn't any.

Thanks for the information.
and this is what I did, originally I thought I had accidentally selected the wrong partition, but it seems since there is no recovery partition, I did it wrong from the start.
Q: I'm guessing this is why when you do load TWRP (the correct way, which I did once, following a guide) without a custom ROM (still using Oxygen OS) that the OEM recovery overwrites TWRP or the OEM recovery is called up at the next reboot into recovery?
Q: I understand, at least in theory the benefit of the A/B partitions, what is the benefit of eliminating the recovery partition other than giving more control of the phone to the OEM and OS? Is this setup limited to the stock kernel or mandated to be copied by any potential replacement kernels (this information is new to me, I haven't yet read up on kernels).

How to install TWRP after Magisk?

How to install TWRP after Magisk?
I have a OnePlus 6 running Oxygen OS 9.0 and I managed to install Magisk by obtaining the stock boot image and using the magisk manager app to patch it to include magisk, then I flashed the patched boot.img using fastboot and ADB.
The reason I did it this way is that every time I tried to boot with twrp.img in order to flash twrp.zip, I would run into a screen saying Qualcomm CrashDump Mode and TWRP wouldn't boot.
Now I want to install TWRP and I was wondering if there is any way of doing it by using Magisk, so I wouldn't have to boot twrp.img.
Any help would be greatly appreciated.
Same problem here. Already tried to boot every version of TWRP without success.

If you have magisk manager with working root.... Then YES you can.... Just download Official TWRP app from GPlay... Open it give root permissions and follow the onscreen instructions.... Thats it...and yes use the zip not the img file

But there's no button to flash, I open the app, select flash recovery, select device, but theres no button to flash it.
See screenshot
do you have fastboot and adb installed on your computer? I assume so as you have oem unlocked to flash magisk, correct?
Copy the TWRP file that ends with .img to your desktop
if so, open a command prompt (windows key +R and type cmd press enter)
type "cd desktop" without quotes and press enter
type fastboot boot "twrp.img" (whatever the file name actually is)
Congrats, you are now in TWRP. But wait, there's more! if you reboot to system or other wise leave TWRP at this point you will revert back to stock. to flash recovery onto your device permanently, install the TWRP.ZIP (The ZIP is IMPORTANT) as it changes the boot on the OP6 to have the TWRP image (oh, by the way, there is no recovery partition on OP6 like previous devices [Thanks A/B partition!])
Now you can reboot to your hearts content. remember if you update OOS, you will lose the custom recovery, so flash the TWRP.zip after every update!

Yes I have fastboot and ADB on my computer (Linux btw), and as I mentioned it the first post, I already tried that, except that instead of booting into TWRP after "fastboot boot twrp.img" I got to a screen saying Qualcomm CrashDump mode (see attached image (the image might not be exactly the same as mine, I found that on the internet because I don't have my computer to reproduce it now)).
super odd. maybe your boot image is corrupt? still doesn't explain why fastboot boot isn't working though... Try bluSpark's TWRP image. it's a solid build and I am not having issues with it.
https://forum.xda-developers.com/oneplus-6/development/kernel-t3800965/page17
or you can also try swapping to the other partition by typing 'fastboot --set-active=_a' (or fastboot --set-active=_b) and booting to that recovery.
if that doesn't work for ya, try and restore stock via fastboot is my only suggestion:

I wonder if this problem has been solved? After having Root without TWRP since last year, I decided to flash TWRP now because I miss having a Nandroid backup. But just like op, right after I type in "fastboot boot TWRP.img", I end up with that Qualcomm crash dump error, resulting in a fastboot boot loop every time I restart the phone. My only recourse is to use the MSM flash tool that reflashes everything and returns the phone into factory stock. In the process wiping out all my data. I don't think there's anything corrupted
EDIT: the problem wasn't the procedure; it was the damned bootable TWRP .img files. I downloaded different TWRP.img versions, and they all failed to flash into temporary TWRP, except for this one that I found here: https://drive.google.com/open?id=1CJoBQ5ZuAExv27XLWwLMFYfHoLEu5YFJ You can use this bootable .img to flash any TWRP version compatible with your device
Does it work for Android 10?

Hello I'm having magisk root access and official TWRP app but can't use it for NAndroid backup, how can I use the app for backup and fishing custom ROM?

Anyone please let me know the OOS 10 and TWRP/Magisk Situation...

I am currently on OOS 10 OB2/31 and can't seem to find a way to install TWRP and Magisk. Found ways to install TWRP and Magisk via patched boot images on OOS 10 stable but not for OB2/31.... anyone know why it's not as simple as flashing TWRP via fastboot?
I also have a problem

Because OnePlus upgraded the bootloader in their OOS10 release. One of the changes was disabling the fastboot boot command that you usually needed to boot to TWRP. Without that command, you had to flash the TWRP img files onto the boot partition first in order to be able to boot TWRP.
There are many -- maybe a bit too many -- guides on how to install TWRP on OOS10. Here and here are some I found.
The gist of it is to boot to TWRP by running the fastboot flash boot twrp_file.img command, rebooting to recovery, then flashing the twrp zip file. And that's pretty much it.
PS In my case, I wasn't able to reboot to TWRP by using mauronofrio's twrp-3.3.1-14 version, and had to use his twrp-3.3.1-11 instead.

To be fair, the only difference between this method and the old method is just one word and manually rebooting to recovery. You still have to flash the twrp.zip after flashing from bootloader file to install TWRP, so it's not too radically different.

Because OnePlus upgraded the bootloader in their OOS10 release. One of the changes was disabling the fastboot boot command that you usually needed to boot to TWRP. Without that command, you had to flash the TWRP img files onto the boot partition first in order to be able to boot TWRP.
There are many -- maybe a bit too many -- guides on how to install TWRP on OOS10. Here and here are some I found.
The gist of it is to boot to TWRP by running the fastboot flash boot twrp_file.img command, rebooting to recovery, then flashing the twrp zip file. And that's pretty much it.
PS In my case, I wasn't able to reboot to TWRP by using mauronofrio's twrp-3.3.1-14 version, and had to use his twrp-3.3.1-11 instead.

I have successfully installed TWRP and Magisk with the help of those links. Thank you again for your help.

Thank your for the in-depth explanation.
Just download oxygen updater and install 10.0.1 and be done with it

LZMA (Elementalx), TWRP, Magisk -> change LOS 18.1 recovery to TWRP in order to get root access,

So, backround is, I want to use AFWall+, which requires root, which I would like to use Magisk for.
In order to get Magisk I need TWRP, I learned so far.
I run LOS 18.1 and I used the lineage recovery/fastboot to flash it (according to the offical LOS-guide).
Changing the recovery is not the easiest thing for me.
Found this thread: https://forum.xda-developers.com/t/from-lineage-recovery-to-twrp-recovery.4253669/
but this seems to be very Samsung specific using Odin (I use a Pixel 4)
I also tried this guide: https://www.droidwin.com/boot-into-recovery-from-fastboot-mode/
but this just "deleted" my OS.
This is why I will be asking a few questions prior starting a new attempt, so please bear with my incompetence
At TWRP I read, I have to install a LZMA ramdisk kernel in order to get TWRP (https://twrp.me/google/googlepixel4.html).
I would go for elementalx, assuming it does support lzma.
From here things are getting tricky for me.
TWRPs guide tells me to get the kernel first, at Elementalx I get the instructions to use TWRP to install
It does say however its not neccessary to install TWRP permanently, but I would like to, because no matter what I want to do with my phone it requires TWRP. So I would like to change the recovery permanently.
The easiest way to do all of this seems to be this guide: https://elementalx.org/how-to-install/
But that will not change my recovery permanently...
What I would do (using a videoguide, because you know, I'm a noobish newbie):
1. Download TWRP img + zip, Magisk zip, Elementalx zip to my fastboot folder
2. Copy the Zips of TWRP, Magisk and Elementalx to my device
3. On my PC -> in the fastboot folder I run cmd as administrator
4. boot into bootloader
5. using cmd -> fastboot boot twrp.img
6. using TWRP -> flash the custom kernel
7. using TWRP -> flash TWRP
8. check if TWRP was proper installed: in TWRP -> boot -> recovery
hopefully the recovery was replaced
9. using TWRP - > flash Magisk
10. reboot
Would anyone please tell me if this will work?
Is there anything I need to do to avoid horrible things to happen?
This is not a request to blame something that could happen on someone afterwards. I just want to minimize the risk...
You can just flash the kernel from fastboot no twrp needed. Just fastboot flash boot boot.img.
You can have magisk patch a boot image then flash it from fastboot as mentioned above.
Usually its just recommended to fastboot boot twrp.img instead of flashing it to the actual device incase you want to revert back and install an OTA.
You can also just download the magisk apk from the device to patch the boot image, flash kernel from fastboot, then reboot with root and have magisk finish doing what it needs to do.
Thank you.
TWRP got stuck booting: I see the logo, "teamwin" and the version used 3.5.2_10-0
Everything was up to date, I'll try it again with an older version of TWRP.
Well, I dont know how to boot into LOS. It just froze on the mentioned screen.
Has anyone a idea what to do?

Ok, I tried it my way - it wont work (of course). Maybe TWRP is still not supported for Android 11.
Now I'll try it your way (thx again).
In order to flash the kernel, I'll have to unzip the elementalx file, I assume. And boot the avaible image, which is called "dtbo.img".
I'll give this a go...

fastboot flash boot boot.img did not work. I renamed the file to boot.img (did not mention this before).
Tried it twice, but nothing worked afterwards, not even recovery and I was not able to turn the device off.
Had to flash LOS again.
I also tried flashing the kernel using sideload while flashing the rom again.
Sideload did work, BUT the wifi was not working at all.
I dont want to bother you, but might there be another way?

That is all. Keep in mind things like wifi might not work if you forget to flash the kernel modules! - Just be sure it is always a 2 step process.

This is what I am experiencing when using sideload. It does install the kernel, but wifi wont work. I guess I do need a working (permanently or temporarly) recovery.

Wifi is usually a kernel module that gets loaded through an init script on boot. It's possible to build the wifi module built-in to the kernel, which makes it so it doesn't have to load separately through an init script.
So if youre not using the stock kernel you'd have to ask whoever makes the kernel you are using.

Magisk should not be that complicated. All the hard work has been done and can be found in Magisk documentation. There are install instructions for just about any type device and if there is LOS for your device I'm sure it is covered. The latest Magisk is not TWRP flashable the same way as it used to be and newer devices often don't have ramdisk in boot image and root is achieved thru recovery instead. You referenced several threads and guides but no indication of Magisk instructions. Read the Magisk installation instructions for your device type, they're not just suggestions, they work.
