Pixel 4 - Google Pixel 4 Questions & Answers

My pixel flame is already upgraded to 11. Can I flash stock 10, then flash twrp recovery? There is no recovery for 11. Do I need to even set up phone before flashing twrp? Bootloader unlocked, rooted with magisk, will perform factory reset tho,

As far as I know, you can flash back to 10. You will have to leave the -w in the flash-all file and let it wipe your phone. If there is a working twrp, you fastboot boot the appropriate twrp image (in twrp) flash appropriate twrp zip, flash magisk, reboot. You should be rooted with twrp installed.

Cannot boot stock kernel

Hello, I want to switch from Franco to Elemental X kernel, I read that first I must go back to stock kernel.
Here's what I do:
1) download factory image angler-n2g47w-factory-bd87661a.zip
2) unzip factory image
3) unzip image-angler-n2g47w.zip
4) copy boot.img into fastboot directory
5) adb reboot-fastboot
6) fastboot flash boot boot.img
When I reboot the phone stucks on first page with the google logo and the lock at the bottom of the page.
Fortunately I can go back to twrp, reinstall franco kernel, reboot the phone and everything works fine.
Can someone please help meto find out why I cannot boot stock kernel?
Thank you in advance
Dirty flash your rom together with stock boot.img, or do a factory reset.
Dirty flash is not working, before factory reset I need a backup.

Backup with twrp, unpack the zip in the factory image, wipe system and caches with twrp, flash boot, system and vendor.img with twrp from the unpacked zip. Why does dirty flashing isn't working?
Edit: your bootloader is unlocked, right? You didn't relocked

Dirty flash the whole stock image.
Remove the -w from the flash_all script. It is the option to tell fastboot to wipe and you don't want a wipe of data.
I dirty flash like this for stock all the time.
Thanks I will give it a try ??

Dirty Flashing ROM (pure nexus by the way) and boot.img from stock cause a bootloop
and I never relocked bootloader I will try flashing boot+system+vendor.img
OK, as you wrote before I thought u are on stock rom with Franco kernel, now it's pn. A bit confusing, if u are planning to switch between roms a clean flash is always recommended.

TWRP Mount Decrypt Data

I purchased a used Nexus 6p from ebay. I've unlocked the bootloader and installed TWRP. When I boot into recovery, I get a screen that's titled, "Mount Decrpt Data". It wants me to enter a password. I don't have the password. What are my options?
I want to root the phone and install custom ROMs.
@msmcintosh- The 6P defaults to data encryption on first boot. You need to do a factory reset and before booting to the OS install TWRP and then boot back into TWRP (reboot recovery). If you want to keep your data unencrypted you now have to either flash SuperSU or a custom kernel. Either of these will disable the force encrypt flag. Also make sure you are installing v3.1.1.0.

I managed to screw it up. I'm stuck at the Google screen. I can boot into TWRP. I had tried to install Pure Nexus, GApps, Magisk and Franco kernel, but obviously didn't do it correctly. How can I recover my phone?
Uppdate: I download and installed the Oreo factory image and flashed it. Then TWRP. Now to figure out what went wrong flashing Pure Nexus. I'm coming from a nexus 6.

I keep screwing this up. I have TWRP, factory Oreo, rooted with Magisk. I made a backup in TWRP. I per Pure Nexus instruction, I installed the Vendor image, Pure Nexus ROM, GApps and Magisk. The system won't boot. Gets stuck at the Google screen. Can't boot into TWRP either. I can reflash TWRP, but the backup is no good (gets stuck at Google screen). I end up reflashing the factory image and TWRP. Then it will boot into Android.
I'm not sure what I'm doing wrong. It was easy to do this on my Nexus 6.

Not sure what you are doing wrong with the clean PN install, but you can't downgrade from O to N by flashing an older PN ROM. You may get more specific help in the dedicated PN install thread by nathanchance.

You have to flash TWRP, enter TWRP and then reboot directly to Recovery. That way, TWRP will modify the system so it will not replace TWRP with stock recovery.
Flash TWRP;
Boot directly into TWRP;
Flash Magisk with TWRP.
Magisk should prevent the stock recovery from replacing TWRP.

you need to flash supersu or magisk right after flashing OOS to prevent OOS from overwriting the recovery with stock one, as mentioned above..

Bootloops after flashing Magisk OOS 5.0.2

I've been getting bootloops after installing Magisk on my OnePlus 5 unlocked bootloader , rooted before at 4.5.15.
I directly updated it to 5.0.2 which resulted in many errors in the end had to flash it completely and then clean install the ROM .
The ROM works perfectly with almost no trouble.
I then flashed almost all Magisk versions I could get hold of (14.5,15.2,15.3,15.4(beta))
But none of them could get past the boot animation.
I've also flashed the no Verity mod file both before and after the flashing of Magisk nothing worked.
But everytime after all this I flash the Magisk uninstaller and I get easily get back to using the device but without root.
Anyone help me rooting this ?
The ROM has been downloaded from official OnePlus website and the twrp I'm using is the codeworkx version.
First do this then tell me how it went.
1. Boot to fastboot and flash twrp-3.2.1-0-universal-codeworkx-cheeseburger.img via command window, make sure you have adb installed on pc.
2. Then boot DIRECTLY to twrp.
3. Dirty flash OOS 5.0.2 over your current rom in twrp and then wipe dalvik and cache.
4. Then boot into fastboot DIRECTLY again and flash twrp-3.2.1-0-universal-codeworkx-cheeseburger.img again.
5. Boot into twrp directly and flash Magisk 15.2.zip
6. Finally boot into the system.
7. Optional: then you can go ahead and update Magisk via it's own flash tool.
I'm already on 5.0.2 so do I dirty flash it again?

(help me) how to install twrp on android 10 fw407?

I reinstalled fw 060 and lost twrp, then I continued to upgrade to fw407 and started reinstalling twrp and now I can't install twrp anymore, I have tried many ways (still unlocking bootloader). Everyone help me reinstall twrp.
is your bootloader locked or unlocked?
Twrp flashing process is same as earlier. Unlock bootloader if it is not already and flash recovery from fastboot. Reboot to recovery before 1st boot...
