Does TWRP work on android 7.0?

If I upgrade to 7.0 on my nexus 5x, will i be able to install twrp as i normally would through fastboot?

You need to decrypt the phone for it to work.

Hmm anyone got the 7.0 recovery? I installed it thinking it would work but I want to keep the system encrypted. Does the stock 7.0 recovery mount system? I want to mod my build.prop dpi.

I just tried 3.0.2-1, and it worked. Before that, 3.0.2-0 also got stuck at the splash screen. However, I wasn't able to root. I tried installing SU via TWRP, but it didn't successfully root.

I had no issues obtaining root with the new twrp on an encrypted phone.

Am I the only one who encounters the flasing of recovery not sticking? After system reboot, then going back to recovery, it reverts to stock.

Flash twrp, while still in bootloader volume down to reboot bootloader, hit the power button, volume down to reboot recovery, hit the power button. Twrp should stick now.

If you decrypt it first by flashing the modified boot.img, and then flash recovery and reboot it should stick and work right? Can you kindly describe your steps?

In my case I updated mine from DP5. I had my DP5 decrypted and rooted and update it using the flashfire app to flash the ota. I don't think any of the existing modified boot.img will work on the final release yet idk mate.

-1 installs, but two issues if you're encrypted:
1) TWRP doesn't stick. After a restart, you won't be able to get back into TWRP and need to reflash it.
2) Installing SU via TWRP doesn't work. It runs into an error if you read the responses during the flash in TWRP.
We'll just have to be patient until the devs do their magic on the encrypted version.

If you root using phh's superuser and magisk, TWRP will stick. His solution also allows you to use Android Pay with root, albeit with a little hoop-jumping
http://forum.xda-developers.com/android/software/mod-magisk-v1-universal-systemless-t3432382

I had the twrp not sticking issue in the past. What has worked is to boot twrp, not flash it, then flash SU. Then boot back into the bootloader and flash twrp.

Stuck rooting

Hi all, so I have Verizon's Pixel XL. I have unlocked it successfully and had rooted. I asked on the forums about upgrading the OTA update and was told it was fine. After doing so, I noticed my SuperSU was gone (although I might have lost it earlier and not noticed). So after trying to get it back and keeping getting stuck, I bit the bullet and ADB sideloaded the factory image from google (NDE63X) and got it able to boot up. Yay.
So then I ran the 'adb reboot bootloader' command, then verified my device was connected with 'fastboot devices' and finally I ran 'fastboot boot boot-to-root.img'. And here I am, stuck on the splash screen again.
So I looked around and saw some mentions of people that had used older versions of Chainfire's SuperSU. I tried the newer one (2.78 SR3) and the same thing happened. I do see that there is a SR5, but I also see Chainfire's comment "Do not use the SuperSU ZIP on work-in-progress TWRP releases for Pixel, it will not work - use the model specific links above instead.
I can get it to run just fine without using chainfire's supersu...but then I don't have the supersu app or any real gains from having rooted.
So, I feel like I must be doing something wrong. Any suggestions?

@smokeydriver,
You probably should update your Android SDK package. This problem can also be caused by an obsolete fastboot.

The OTA update I took only got me to a new version of 7.1, not 7.1.1 (from NDE63P to NDE63X). It still shows an available update to 7.1.1 which I have *not* done.

Try using the Unified Toolkit. It saved me from having a bootloop disaster when I tried upgrading from 7.1.1 due to poor instruction availability around the web. It should fix whatever problem you are having, even if that means flashing the factory image first again.

I've tried, but keep getting an error 21 code that it can't install...I tried this with SR5 and SR2.

How I Rooted
Personally, I'd flash to latest OTA via Unified Android Toolkit before starting this process.
Then use Minimal ADB to flashboot boot twrp.img (The Alpha2 Version)
AT this point you should already have 2 zips on your phone, TWRP-RC1 and SuperSU v5.
Flash TWRP, then SuperSU.
Reboot into OS, confirm root, give it 5 minutes.
Reboot back to Recovery and flash Kernel if desired.
Do not flash root with RC-1 (thats why we flashed root while using Alpha2 adb twrp.img), do not restore backups made with Alpha2 using RC1 or vic versa. AKA Backup and Restore with same version of TWRP.

Ok, I must be doing something wrong on a very basic level. It gave me error 21 (signature verification error) when trying to use the unified android tookit to install 7.1. Anyways, I'll just move on and skip that step and see what happens.

Flashing SuperSU SR5 works just fine with TWRP RC1. All you have to do is delete the file you're told to before flashing.

I transferred those 2 files to my download folder on my phone, ran the twrp.img script, and then when I go in...the file names are not normal. Everything is random letters and numbers. Again, I feel like I'm making some stupid basic mistake that I don't understand (and I've rooted plenty of phones).

Ah, I see. I misunderstood. I thought you were just under the impression that you couldn't flash SU with RC1. My apologies.

Ok, so can someone tell me why I am getting stuck with 1 thing. I go to my stock recovery and into ADB sideload. When I tell it the file, it keeps failing to verify whole-file signature. What is wrong with this one step?
Or alternatively...when I'm in TWRP Alpha 2- why are all the files within the sdcard random letters and numbers?

Twrp is not decrypting you're data. Try rebooting twrp from fastboot a second time.

How to flash official nougat without wiping internal storage?

Hello all!
I am currently on OOS 3.2.8, and official TWRP. I have read all the instructions on the forums but all lead to one option, formatting internal memory. So, my question are:
1. Will flashing oos 4.0 work with official TWRP or 8 have to use modified 28 version?
2. How can I flash oos 4 with modified TWRP and not have to wipe internal memory?
I would appreciate all the responses. Thanks

I was the same predicament as you. I finally took the plunge and now I have Nougat running on my OP3. Here is what I did :
Start: OOS 3.2.8 w/ custom kernel and modified TWRP
1. Flash stock recovery (Google for a forum post in the OP3 forums on downloading the stock recovery and flash it through fastboot)
2. Reboot and let 3.2.8 start
3. Download Snap VPN and change the country to Canada. You will be prompted for the system update.
4. Let the update download (~1 GB)
5. Install the update. You may see an error of the installation may fail as your phone is rooted. Ignore and go ahead.
6. The installer will now boot to stock recovery and reboot with Nougat. All settings and apps will be maintained
The only catch is that you may have ext4 instead of f2fs. I am okay with it for now... But your mileage may vary
All the best!

Edit : Nougat running on my op3.

Are you rooted? Are you encrypted? What file systems are you using for your partitions? You're not giving full information. Why is formatting not an option if it'll give you the results you want?

To get to F2fs (I do recommend it)
Take a backup of your Data partition. , copy it to your pc with "adb pull /sdcard/Twrp/whatever".
Now go to Twrp>Wipe>Advanced select data and click on change file system. Change it to F2fs. Now restore your backup (Reader the guide all info is there). Profit!

I don't have any issues with ext4, infact i do feel ext4 is more stable than f2fs so file system is my last concern. Thanks for your method, but then how did u root again? Installing nougat is fine but what after that? I have read that you can't use modified twrp without formatting internal memory first, as it'll show you the pin issue. Let me know how do you propose a safe method to achieve root.

Yes i am encrypted, rooted, stock OOS 3.2.8 + Franco kernel. Official TWRP(not modified). I am using ext4, never used f2fs at all. The time to backup data and then to restore it all back is the reason formatting is not an "preferred" option for me. I can do it, but i would have to wait until i find enough time to do the whole process. I am in a full time job, so i hope you would understand.

Well this again defeats the purpose of my original question, but thanks mate. I would definitely read the guide if decide to switch to f2fs.

@abhibnl. BTW your encrypted. So the modified TWRP won't work.
How to fix:
Wipe Userdata with Fastboot / fastboot erase UserData
Boot into Twrp modified twrp.
Flash OOS 4.0 flash SuperSU and let it boot
You should be decrypted DO NOT install a boot password since you will be encrypted again.

I haven't rooted my phone again. My only reason to root is to install Adaway to block all ads. With DNS66 and Adguard, I have little incentive to root my stock nougat install.
Edit : I had encryption during 3.2.8 and it carried over to 4.0

Thanks a lot for informing me mate. I really don't want to decrypt my storage as of now. I guess flashing stock recovery is the only solution now. Will hope someone would pick up the twrp and update it.

Seems like stock recovery is the best way as of now. Seems like I'll have to love without root until someone updates twrp to support encrypted storage.

I haven't updated to Nougat yet, but I looked over Chainfire's SuperSU changelog and its installation script and both of them confirm that from March installing SuperSU prevents forced encryption. Also many guides suggest installing it as way for disabling forced encryption. Of course you have to flash SuperSU just after flashing ROM, before booting the system.

That i already knew mate. But i WANT my storage to remain encrypted. And that's the issue with modified TWRP. You can't enter into recovery on that if your storage is encrypted.

Again, "You can't enter into recovery on modified TWRP if your storage is encrypted." So i won't be able to enter into twrp in the first place, let alone flash anything.

In the same boat as you. I have OOS 3.2.8 encrypted, rooted and TWRP 3.0.2-1.26. I too would like to update but have way to much stuff on my phone to back it all up and restore it. Hope you or someone come's up with a solution. I will be following your thread.
Thanks.

Go to twrp. Press backup. Select only data. Save to PC youre backup for safety..
3.2.8 it's Android 6, 4.0 it's Android 7. Some apps might not work from base to base.
If you want to change to F2FS it will format youre phone, wipe phone full internal memory. If you want to change it back to ext4, same.
Clean flash, full wipe it's always better.

My suggestion (and my steps are in #1), install stock recovery, install snap VPN, download the update and install (ignore any errors on root). Once done, you will have Nougat with stock recovery, encryption maintained and all app data also intact.

This is the last resort brother. With this method, unfortunately I won't have any root available. The only way now is to wait for updated twrp.

Well, I tried something, waiting on it to finishing booting and see how it went.
I flashed twrp-3.0.2-1.28-oneplus3p version,
Flashed the OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2af7.zip inside TWRP,
Flashed SR1-SuperSU-v2.79-SR1-20161221223537.zip right after flashing OTA zip.
Its rebooting and says Android is upgrading. Fingers crossed.
EDIT: Its booted and I am on Nougat, didnt lose my data and phone is still encrypted!
Edit: Ended up having issues with settings app locking up. So, I went a different route and its all working great now.
Downloaded the stock recovery image and renamed it to recovery.img
Make sure after you rename it its not named recovery.img.img, If you have show file extensions enabled on your pc you should already see the file extension.
Rebooted to bootloader - adb flash recovery recovery.img
Using the volume keys and power button selected - reboot recovery.
Now in stock recovery - flashed OnePlus3Oxygen_16_OTA_035_all_1612310359_e10cadfb2af7.zip
After rom is done flashing, went right back into bootloader. Did not let my phone reboot to start the OS.
Renamed twrp-3.0.2-1.28-oneplus3p.img to recovery.img
adb flash recovery recover.img
Powered off phone and Manually boot it into recovery by holding Power + Volume Down button.
Phone booted into TWRP
Flashed SR1-SuperSU-v2.79-SR1-20161221223537.zip
Wiped cache / dalvik
Rebooted system from TWRP and waited. System is really smooth now, no issues yet. Been playing with it for awhile now.
During the booting up process it might take a minute and it will reboot twice. Dont get nervous like I did thinking it was going to start bootlooping. It booted just fine. I read in a nother thread that SuperSU is what causes it to boot twice.
So......Now I have OOS 4.0 Nougat, Rooted, Encrypted and everything seems to be working fine.

How to Root Using SuperSU and TWRP on Oreo OPR6 Official Release

After a bit of trial and error, I managed to find a combination of files and actions that allowed me to successfully root my 64GB Pixel C on 8.0.0 by installing SuperSU via TWRP.
Steps:
Perform a clean installation of the official release, found here
Use the unofficial 3.0.0 TWRP release found in this thread (direct download link here) and boot to recovery ("fastboot boot [TWRP filename].img") - the latest official 3.1.1 TWRP did not work, either via flashing or booting
ADB sideload SuperSU 2.82SR3 found in this thread (direct download link here)
Hope this helps!

Stuck at TWRP after
Flashed the TWRP from the link and side loaded the SuperSU, now my Pixel C is stuck at TWRP on reboot, any idea ?

Thanks. My problem was my pixel kept booting to TWRP even selecting to boot the system, kind of strange. I think I missed your first step, the pad was OTA updated to 8.0 from 8.0 Beta release. I will try again with flash the factory image of 8.0 first.

It's driving me absolutely mad. I just got a brand new Pixel C today. It's updated to the latest Oreo but nothing else has been installed yet. I unlocked the bootloader and copied the SuperSU zip file onto the device via USB file transfer from my PC, then I set up a password. I'm booting (not flashing) TWRP because all I want is root.
When I'm prompted for a password in TWRP I'm told it's invalid. I also tried "default_password" and that's invalid, too. I looked all over for a solution and found a modified TWRP that doesn't prompt for a password but it won't decrypt the internal storage.
I'm really pulling my hair out here. I can't figure out why it's working for some people and not others.

Try format userdata, then boot straight into twrp
Command is "fastboot format userdata"
You also have to flash SuperSU while in twrp to stop the tablet from encrypting again.

I'm confused about "stop the tablet from encrypting again". I know TWRP needs to decrypt the data partition to access it, but are you saying encryption won't be re-enabled when I reboot the system? I had to ask because it sounds strange that installing the SuperSU zip would mess with encryption.

If everything goes to plan yes.
You can encrypt again if you wish through settings once the tablet is booted up

Does this mean when I flash the factory images for the monthly updates and need to root the device again that I'll be wiping all userdata each time?

No just use flashfire to update and keep root, it won't encrypt the tablet. You can still boot official twrp as well after using flashfire to update as your tablet shouldn't encrypt.

Is removing encryption something everyone is doing, or is it just a workaround for the people who can't get TWRP to work? I never ran into anything like this before.

Use FDE then and it reportedly works.

Just curious though, is this a standard prerequisite for using TWRP and rooting *all* Pixel C devices?

Don't know, only telling you what I did cause I had the same problem as you

Well I'm finally rooted. I didn't change the encryption, just tried a different method and after several tries it finally worked. I used adb sideload inside TWRP after canceling the password screen. Odd that it took several tries, though, to get through it without generating errors. We'll see how it goes next month.

I have had a lot of trouble with rooting Oreo...
I started out trying to use Magisk but gave up after many attempts. Every version, and every kernel I tried resulted in booting to recovery and not system. I could have tried the ADB method but I actually want to have TWRP so I didn't try that.
By the time I tried SuperSU my factory image had had an OTA and many apps & files installed so I can't say my system is "clean" but I have Fastboot flashed the stock boot image many (many) times to recover from whatever Magisk does to the kernel. I never looked all that hard for this unofficial TWRP people talk about so I used 3.1.1-1. At some point I converted to File Based Encryption because it is so much nicer to use, and so TWRP cannot decrypt my internal storage, but the workaround is to put zips and images on a USB drive. It also does not ask for a password. So far so good, I have my workarounds. I do also have this weird error where TWRP cannot unmount the system but I can flash kernels without problems. I have chosen to keep system read-only for superstitious reasons. I think it will fail if I look at it funny sometimes lol.
From this state I flashed the latest SuperSU and it booted! So I do have root. I still would like to try Magisk for the modules but it seems this isn't ready. However, my trusty old terminal app hangs at the su command... and several kernels will crash my tablet... so it's "working" but there is more to do. And literally just now I see I have an OTA. lol.

I followed the original instructions and got rooted with the latest version of Oreo. But, TWRP still wouldn't flash correctly without causing boot loops.
I finally got it resolved by using the original instructions, then loading the Official TWRP app from Google Play. I used the app to flash twrp-3.1.1-1-dragon.img.
Everything is working properly now. I have 8.0.0 (OPR1.170623.032, Nov 2017) loaded and rooted, and the Pixel C will boot into TWRP and see the encrypted data.

Is it posible to flash latest Oreo stock factory image https://developers.google.com/android/images ryu-opr1.170623.032-factory-020f1cf9.zip using stock TWRP or do I have to side load it ?
I'm getting a Invalid zip file format error in TWRP when I try and flash it

Help Updating to December Security Patch

I'm running the stock rom on the November patch. I have TWRP installed with Magisk and the Kirisakura kernel. I've read and Googled for a solution and still can't get it to work. I have the latest ADB told installed but I am unable to push the update through. Can someone tell me what I'm missing? This used to be so much simpler lol. Thanks in advance.

From what I understand you can not do ADB in TWRP to install an update. What I did was download the factory images, remove -w from the flash all.bat. flashed the images and let the phone boot normally. Once I knew it was running I went to the bootloader and booted TWRP temporarily. Once that was up I flashed Magisk and then my kernel
I don't install TWRP anymore.

Adding to what hatdrc said, you want the full image, not OTA, and install from your PC in fastboot mode. If you are concerned about saving your data, remove the -w switch from flash-all.bat first using a file editor like notepad. Have the twrp.zip, kernel.zip and magisk.zip files already staged. I personally don't boot to system first (but you can), I "catch" the reboot after flashing completes with the volume down button to reboot to fastboot mode. Then fastboot boot twrp.img, and then install twrp, kernel and magisk zips all in one go using the "add more zips" button in twrp. Every month when you update, you'll lose twrp, kernel and magisk, so those have to be reflashed each time. You'll soon get used to it and can do the whole thing in about 5 minutes consistently. Just make sure to pre-stage the 3 zip files on the phone before you start. Best of luck.

I tried that but couldn't get it to work. I downloaded the ADB tools again just in case there was an issue with that. I'm going to run the flash-all script again to see if I can get it to work.

if whats suggested above doesnt work, you can make the OTA work....download the ota to your PC, boot to Android Recovery (not TWRP), apply the ota via ADB from the menu. Whenever I have "odd" issues applying the Full image, this always works for me. Obviously you need to re-root after.

Yes it does. TWRP replaces the stock recovery.

Ok, I got the flash-all script to run. My brain shut down and I was running the wrong command.
