TWRP bootloop after flashing TWRP Solved

Don´t know if anybody had this kind of Problem before. Couldnt find anything.
Was on Stock V image with cutom kernel flashed via fastboot and SU flashed via fastboo boot to root.
Problem:
bootet TWRP via fastboot with newest drivers. Flashed RC via booted TWRP.
Wanted to reboot system, but was stuck in a TWRP bootloop. No chance to boot into bootloader also. Even tried changing slots in twrp but still only bootloop to twrp.
Than I thought about sideload because that's what I did with latest ota image from Google.
Here is what I did:
sideloaded the ota.zip via TWRP from PC "adb sideload ota_file.zip" ota_file should be the name of your ota file
It gave me an error, but after rebooting system all fine again. Back to stock V and bootloader is there again.

Easier thing to do is flash boot.img from the factory image to boot_a and boot_b if you are having issues.
This problem occurs when you flash TWRP if you have root installed. To avoid, remove root before installing TWRP.
Oh, I should mention to get into bootloader from TWRP, simply use the adb command "adb reboot bootloader". Should work, worked for me.

I just have avoided flashing TWRP altogether. I rarely need to flash anything, so it can wait until I am at work or home to use a PC to BOOT TWRP each time I need it, instead of flashing it.

Until it gets a little more stable on the Pixel, this is probably a good idea.

Good idea. But I M sometimes flashing when I am at or on the way to work.
Flash junkie needs his daily dosis

I know its already solved, but here is what helps (for future):
Just flash SuperSU (latest Version)
Done. This will patch the boot.img so your phone boots in the OS again.

I have this issue and flashing supersu didn't fix my problem. Will go to factory image flashing.

Thanks! This worked for me.

EDIT: Never mind, I missed the comment guiding ppl to flash SuperSU. I suppose that when this thread was posted, that SuperSU was still being used instead of Magisk, so solution is essentially the same thing I'm recommending.
I think this thread is missing the much easier solution here:
I just ran into this issue with my Pixel 2 XL when I tried to update my TWRP version from 3.2.1-2 to 3.2.3-0. Here's how it went:
1. Downloaded the TWRP zip, md5 and so on from the official TWRP website for the Pixel 2 XL
2. Booted to TWRP and installed / flashed the zip of TWRP 3.2.3-0
3. Wiped dalvik and then chose Reboot to System from TWRP -- the phone booted right back into TWRP
4. Tried again to reboot the same way. Same result.
5. Installed / Flashed the 3.2.1-2 TWRP zip which was still on my phone, in order to revert to the previous version, and then Rebooted to System -- same result
6. Flashed 3.2.3-0 zip again, then flashed the Flash Kernel that I've been using, and then Flashed the Magisk v16.0 zip that I used to root, then chose Reboot to System -- AND IT WORKED; the phone booted normally and now I'm updated to the latest TWRP successfully.
tl;dr - The solution is to flash Magisk again after updating TWRP. Pretty sure this goes for kernel updates too.

Aren't the two systems (Pixel OG and Pixel 2) extremely similar? If they're not, then my advice should be ignored for anyone using the Pixel OG.

Few questions before rooting/twrp

I just purchased the ph1 and plan on rooting the device and also flashing twrp. I've found the guides and everything seems pretty straight forward. The phone should be arriving tomorrow so at this point I'm unsure of the build it will have when I receive the device. I noticed a thread regarding the February update not working with twrp. Has this issue been resolved or will I need to flash to the January version to complete the task? Is the February and January builds mentioned the most recent updates for the device? I've found the links to the essential website but it gives me a error that its server IP cannot be found so I've been unable to check it. Is the site going to be down indefinitely due to no longer supporting the device? Does anyone have a link to the updates hosted elsewhere? The device was listed as GSM unlocked and did not mention any carrier tied to it so I'm assuming it's a factory unlocked device but will have to verify upon receiving it. Is the updates carrier dependant or do they all utilize the same files? Whats the consensus on roms/kernals on this device as opposed to rooting and using twrp on the most recent stock builds? Which Rom would you recommend if I do decide to go that route? Thanks for any advice you can offer, it's greatly appreciated.

Count me in as needing to know this information. I am planning on installing the Android 11 release when it comes out this month and I am currently running 10 Build number QQ1A.200105.032 with February 5 2020 security patch level. Will I need to install the January build to install Android 11?

I ended up receiving the device and it had Android 8 out of the box. I received a update that took me to Android 9 which was roughly 1100mb and another to Android 10 which was a little over 1000mb. The second update automatically included the February security patch. Rather than downgrade to January, I simply patched a February boot image with magisk and flashed with fastboot. I also flashed ElementalX kernel via fastboot. As far as I can tell they are not carrier specific. I am considering going to January now so I can use twrp to test some custom roms. For downgrading to January do I simply flash the January boot image which shows to be about 65mb or do I need to find the firmware in it's entirety? Also rather than down grade and use twrp can I just flash custom roms via fastboot? I would say you might have to downgrade to January to use twrp to flash Android 11 unless it's possible to flash the roms on fastboot, hopefully someone chimes in bc I'm unsure at this point.

Noob question, but what's the advantage to changing just the kernel?

Coming back to XDA after over a year. Realized Google Play Store update ruined my Magisk status, and evetually root (SafetyNet stuff). Here are some notes I took while I flashed in 2019, hope it helps.
1. DISABLE Security (PIN/Pattern/Fingerprint)
2. Backup Internal Storage
3. Boot to recovery TWRP, and backup nandroid.
(must go to bootloader and change slot to boot twrp.img flashed on that boot partition slot)
4. Normal boot and drag drop nandroid backup to PC.
5. Syncthing/Resilio for extra measure.
Have latest OTA.zip, boot.img (same version as OTA.zip), and latest Magisk.zip in root internal phone storage.
Have twrp.img in platform-tools adb root for flashing in fastboot.
twrp.zip is optional stored in root internal phone storage.
Flash OTA.zip update in TWRP. (assuming system is under slot_b)
This will flash to opposite slot, _a.
(I flashed under slot_b and new OTA went to slot_a, I booted back to _b and
old system version remained with broken Wifi becasue I accidentally flashed new boot.img in TWRP image over older system image
in slot_b, without the image flash, I suspect the old slot_b would have been perfectly untouched and rooted, as OTA applied to slot_a)
(Went back to A and new OTA was perfectly fine, although unrooted).
Boot to slot_a (system_a), make sure it runs good and verify version within settings, should be unrooted.
Boot to bootloader (under same OTA slot_a), default recovery should be stock recovery (droid logo) after OTA flash.
fastboot flash boot twrp.img (this will replace stock recovery to twrp recovery, deleting stock boot img as well, breaking OTA slot)
Reboot to recovery twrp (remain on same slot and will run off of RAM, leaving boot partition open to flash back stock boot.img)
Install boot.img (make sure version is correct) boot partition should be back to working condition although unrooted OTA system.
Try booting back to recovery on same slot, and stock droid recovery is back. (you cannot edit partitions from fastboot, hence twrp flip flop)
Try booting to system, it will boot but broken, no wifi. How? Not sure, maybe used old boot partition .img in slot_b to boot to system_a
Then flash latest magisk zip to patch stock boot.img for root.
(if you flashed twrp.img and magisk, then you're patching twrp, which is incorrect.
You want to boot to twrp, then flash boot.img back to boot_a partition, then run magisk.zip to patch stock boot.img in that boot_a partition)
Magisk.zip flash log:

Which TWRP version to install?

I have moto x play xt1562 and on this page i see that there are different unofficial TWRP versions. Which version i have to install? ALso, if i have other custom recovery already installed, like linage custom recovery, do i have to take and precautions?

hi peter,
it depends on which image you want to install. since may 2020 there is a bug in twrp which no longer starts the phone with the ota update.
if you want to backup, delete or install your partitions you can install the current version 3.4.0. when you have everything set up you either have to import the updates manually or use its recovery as with lineage. twrp should also work in version 3.3.0 (or any other version before may 2020).
I am currently using the lineage with lineage recovery and it works. should you need more settings for the recovery you can simply boot twrp without installing! thus it is possible to set everything in twrp and still have the lineage recovery because of ota on the device.
if you want the recovery boot (no install) you have to execute this command:
Code:
fastboot boot twrpname.img
cheers

How to do TWRP after magisk is flashed

Basic information:
My Device: Samsung Galaxy Tab S5e, (SM-T725C)
Magisk: Magisk is installed, using falsh patched image.
TWRP link: https://twrp.me/samsung/samsunggalaxytabs5elte.html
Issue:
Now I wish to install TWRP to my device, but I can't. I followed the instruction on TWRP page, install TWRP app via google play, download the vbmeta.tar and flash it. Now I ended up with the result that I can't get into my system. (When I enter recovery, it's TWRP, when I boot normally, it just stays with samsung logo.)
I managed to reflash the magisk patched image and now I can boot into the system. But how can I flash TWRP, with magisk enabled at same time?
(I use TWRP to flash opengapps because google apps are not included in Chinese version of Samsung system)

I dont know if this works with the latest update, but it certenly worked with android pie and the first android 10 update.
Edit 'I have just seen your device is a different number so may not work'
Instal TWRP without a P.C. for Galaxy Tab S5e (SM-T720) keeping stock ROM.
I wrote this guide because I had difficulty trying to instal a patched version of twrp through odin so I found this alternative way which worked very well for me. Please read all through especially the warning at the end before attempting to...

N9005 problem installing twrp

I have an N9005 device, it comes with default stock rom (5.0 lollipop), the problem is I tried to install the last TWRP version but it doesn't boot into twrp, I can only install old twrp version 2.8.7.0, and I cannot manage to get it to boot into last twrp version, as I want to install an android 12 rom and can't do it unless I have latest twrp version.
What could i do to install an android 12 rom coming from stock rom?

There's no message or screen, if i flash twrp 3.7 using Odín or adb it directly boots normal when i try to boot into recovery, but if I flash old twrp versión (2.7) it works fine

You don't need to install version 3.7 right away. Do a trial with twrp-3.5.0_9-0-hlte.img first, but flash it directly from TWRP, not through Odin. Use the IMG option to flash the recovery partition.
