Question Rooted and booted into twrp but there's no recovery. - Google Pixel 5a

I have my phone rooted. I have the twrp image on my phone and can fastboot into it. But it does not flash as my recovery. I have no recovery at all. Phone boots fine but has screen I have to press the power button twice on before it will boot. Saying unlocked bootloader and unsafe phone don't have any personal data.. Ect. I downgrade from a13 to a12 and an currently running the fsociety kernel. What can I do to A. Get my recovery back and B. Get rid of the boot error screen everutime I boot.

The Pixel series do not have a recovery partition; you cannot permanently install a custom recovery. If you are not using a custom ROM, there is no reason to use TWRP.
Do not try to remove the bootloader warning screen. It is part of Android functioning as intended, and trying to remove it may corrupt your bootloader.

XT1095 Only able to boot into bootloader or TWRP recovery

Whenever my recovery is TWRP I am not able to boot into any type of ROM. Every time I reboot my phone it will be past the "your bootloader is unlock" and always boots straight into TWRP. When I flash stock recovery I am stuck at a image of a Android and it just stays at "erasing..." till it reboots itself. I have attempted to flash different types of roms by sideloading through TWRP and also attempted to flash stock recovery through fastboot with no luck at all.
The issue started whenever I was on stock 6.0 and flashed TWRP. Once I was in TWRP at the end when I was rebooting my phone I said yes to install supersu, which I know now was a mistake. Afterwards I was stuck in a bootloop were I finally attempted to do a factory reset which seemed to have made things worse. That was when I was stuck at the "erasing..." whenever I attempted to boot through stock recovery. Not sure what else to try at this point.
Any help would be great at this point.
I'm in the same boat. Exact same problem with no idea how to fix. I can get into fastboot screen, but that's it. Suggestions? Thanks in advance.

A Stock ROM and Bootloader that will leave bootloader unlocked?

As per another thread, I am having issues (bootloops at the android/moto logo screen) after replacing my Turbo screen. I am unlocked and rooted. I know this cause I was before I replaced the screen (used Sunshine) and had RR custom ROM installed. Still unlocked because I can get to the bootloader screen (Power + Vol Down) and it says "Phone is Unlocked. Status code: 3".
To try to at least get a booting phone: Is there ANY stock ROM and Bootloader that I can flash that will still keep my phone UNLOCKED? I don't want to re-lock it and then have it locked forever (which I think the latest stock updates does). I am thinking that if I can flash a stock bootloader and ROM, then I can reflash TWRP and custom ROM (and get rid of the bootloop).
I would assume that if I had put something together incorrectly then it wouldn't boot at all and I wouldn't be able to get to the bootloader screen.
Thanks for any info/advice.
P.S. I did try just reflashing TWRP but it still bootloops at the same point; and I can't get into recovery.
So, when you boot to bootloader (Phone off, then power and volume down button at the same time), and you then arrow up to "recovery" when you push the button to go there, what happens? Is TWRP not still installed or something? the only reason it wouldn't be installed is if you flashed stock firmware and wiped it out with stock recovery.
Use the hardware method
First of all, you have to turn off your phone.
Then, you need to press Volume Down button and hit power key.
Bootloader mode will be then displayed on your device.
From there, use volume up and down buttons in order to scroll up and down and power key to select.

If your Droid Turbo bootloader is unlocked, flashing stock firmware with bootloader won't lock it. The newest firmware is to PREVENT the bootloader from being unlocked by Sunshine. It won't lock it back.
However, with stock Marshmallow you will have to re-root with older SuperSu beta for initial root. Flashing with newer SuperSu causes bootloops. After you have initial root then you can update to newer SuperSu.
But first tell me what happens when you try the hardware method of getting to recovery.

also you can force the phone to boot to TWRP, even if you don't have TWRP installed on the phone...
fastboot boot recovery.img
Where "recovery.img" is your TWRP file on you PC.
if you named it TWRP.img, then the command would be
fastboot boot TWRP.img
If you need to force the phone to go to the bootloader, the commad is
adb reboot bootloader
and then from there
fastboot boot recovery.img
(where "recovery" is whatever you have named the TWRP file.)
It's basically "temporary" TWRP. It doesn't install TWRP, but makes your phone boot to TWRP from your bootloader screen. It uses the TWRP file (whatever you have named it) from your PC folder. You then will boot into TWRP, can install stuff, make a backup, whatever you want to do. From TWRP, you can even install TWRP!
But you can reinstall your custom ROM, or you can restore a backup -- whatever you want to do from the "temporary" TWRP.
I used this a couple of years ago to use TWRP to make a backup of STOCK Kitkat image. I was booted into TWRP but TWRP was not installed on the phone. The phone was still pure stock, so I could easily make a backup image.
Then I rooted the phone! And made another backup image. It was rooted stock, still with no TWRP installed.
And then last I actually installed TWRP, was rooted and made a backup of that. And posted all those images for people to use. But a lot of people forget that you can BOOT TO TWRP even if TWRP is not installed on the phone. And that "temporary" TWRP (one session) will still allow you to do anything you want.
It's a useful trick to know!

Redmi 4X bootloop after installing TWRP?

Hi,
I'm having a bit of trouble. I had a brand new Redmi 4X, and I was advised to install TWRP, root it, and install the Xiaomi.eu rom until LineageOS is released. I unlocked the bootloader, flashed TWRP, managed to get into it once and now I can't do it again. When TWRP loaded it asked me for a password for decryption but it let me just skip it it seems (not sure if that is the problem) but now I can't boot normally, I can't boot into recovery, but fastboot seems to work okay. How do I go about fixing this?
I've tried reflashing TWRP but I still can't get to it, and I don't really know enough about this stuff to know where I've gone wrong.
UPDATE - I think this is to do with dm-verity and having the stock kernel installed. Now it's too late to undo what I've already done, so I hope to god that someone knows how to fix this.
UPDATE - Right, the problem is solved I think. I had to do an awful lot of googling, and I'm not entirely sure what it was specifically that fixed it. But I found a guide that taught me the fastboot command "fastboot boot twrp.img" which saved the day. Even when my phone wouldn't let me into recovery, it allowed me to flash a no-verity.zip which i think is what allowed me to boot, and it allowed me to flash superSU.zip and then the ROM I was aiming for. And now I've booted into the ROM successfully and hopefully I am rooted and all is well. Plus I can access TWRP as normal now.
Any help would be greatly appreciated
Can you boot into TWRP by pressing the buttons so that you boot directly to TWRP??
Have you tried Command Prompt to boot with commands in to recovery??
And if you get into TWRP you should have everything on the SDCard and then just
format all things except SDCard and then flash from SDCard everything
That is what I would try..and yes it ask for a password but just skip it to get to it
If you can get into TWRP to flash from SDCard then you good to go..if not
Google all the commands for CMD..and plug your phone to the PC and flash everything with the
commands.....
Let us know what is working and what not and what steps exectly you are doing
EDIT
Turn off your device > Press and hold “Power” and “Volume +” buttons at the same time.
After short vibration signal release the power button and wait for TWRP to start.
To boot in stock recovery open “Update” app.
In the setting select “Boot in recovery”.

Thanks for the reply. I can't get into TWRP. Even if I could get into TWRP how would I get files on the phone to flash them?
Is it possible to flash any rom from the pc directly and if it is will this possibly help? I think it's not booting because the kernel is still stock.
I'm not sure what you mean in the edit, how do I boot into stock recovery without being able to boot the phone (and when I have already flashed TWRP)?

Hey, I have exactly the same problem. Latest stock rom, flashed twrp in fastboot and got into the boot loop. Nothing works. I can only enter fastboot. What exactly did you do then? What is this no-verity.zip? I can't find anything about it.
I had a problem
I unlocked bootloader then installed redwolf recovery and took a nandroid backup. After that i rebooted to system but stuck into bootloop, could not boot to recovery, could not boot into system, So the only thing worked was that i flashed fastboot rom with mi flasher. And syccessfully rebooted to system with bootloader locked and stock recovery. So, if anyone have same problem you can do the same. How do i install recovery safely again? Should i use TWRP only? Should i flash v3.1.0 with lazy flasher or v3.2 directly without lazy flasher? I don't want to stuck into bootloader again, have to get all data deleted.

Bootable custom recovery after Pie update?

I downloaded and installed the official Pie update today, then procedeed to unlock the bootloader which was a success. However now I found that the phone wont boot (not flash) a custom recovery (latest TWRP).
I'm only interested into booting a custom recovery so I can root, otherwise I'd prefer the phone to remain as close to stock as possible.
When trying to boot into TWRP using "fastboot boot twrp.img", I get a success message, phone reboots and then gets stuck at the Android Logo (fastboot commands still work, it doesnt say 'download mode' tho).
Any solutions?

[SOLVED] Device recognized in recovery (TWRP) but not in bootloader?

Solution: Not sure why or how, but I got it to actually boot into the new system that I flashed. Now all is good and working as it should
So rooted stock ROM, but with TWRP, unlocked boot loader and USB debugging enabled... I'm No stranger to flashing custom ROMs in TWRP and flashing stock ROMS longhand by fastboot commands.
Using MacOS with latest platform-tools...
So today I decided to flash resurrection remix. Downloaded it to storage as usual for flashing via TWRP, flashed it successfully. Only it would not boot. It started going to the stock boot screens and said it could not decrypt... or something.
Anyway where I am right now is that I can boot into TWRP or boot loader just fine. But in boot loader I can't get get it to see my phone using
Code:
./adb devices
Only... for some reason in TWRP if I do ./adb devices, it sees my phone and reports back the correct device ID.
What now? I want to flash back to stock again, but I don't know how to flash line by line without being in boot loader. But in boot loader I can't see the phone?
I know there has to be hope if I can see it in TWRP. But I have no system I can boot to.
-Peter
Great that it works for you now.
For what it's worth, I think that the reason it didn't boot was that the stock rom had encrypted your phone. Current custom roms unfortunately use a different encryption, so that the whole data partition needs to be formatted. I assume that's what you ended up doing.
As to the bootloader, it was never intended to work with adb, only with fastboot.
