No, you will need custom recovery for that, pitch black is best one

The problem is I updated Pixel Experience and after changing active slot on TWRP I now have the stock recovery

Hello
Same here after installing pixer experience when i try to go recovery , stock recovery come back , how to do , did i have to install twrp again or what?

fastboot --set-active=a
or b
this depends on version of fastboot but you can see all cmd by using "help"
alternatively just run :
fastboot boot recovery.img
***this will boot recovery without installing it but then you can install magisk or install a twrp recovery zip or you can change active slot in the reboot button or tab
**** obviously for this to work you need to put twrp in the fastboot / adb folder and rename it to recovery.img and also open cmd window there with aright click

---------- Post added at 11:22 AM ---------- Previous post was at 10:53 AM ----------
Let me know is that work? If not I give u full guide how to prepare phone for custom rom.
The problem is that I cannot install zip file. Whenever I try to install any file through the CWM, I get the error as per attached.
I tried to reinstall the recovery and the boot files bit it is the same.
Try to change the cwm
dont install that chinese cwm, unzip and instal cwm i've just added, instal by fastboot!!!
Thanks. I'm going home, try it and let you know.
Thanks again
Hi.
I'm still getting the chinese recovery and still not able to install from zip file.
Find stock cwm
Try to instal stock recovery and after install cwm I give u before... Is ur bootloader unlocked?
I did that but still I cannot install zip file.
Ok, try this....
Just post screenshot of ur bootloader and I see what I can do....
Use this guide!
If u still have problem use this whole guide and start from begining, root again, install cwm gain and start with rom from this guide, if it works other roms will work also! So this is the guide:
Get ROOT on your Device
Get RECOVERY on your Device
Get BinDroid.zip on your Device
Reboot in RECOVERY, flash BinDroid_SensationXL_TotalWipe.zip
Reboot to Bootloader and Flash THIS BOOT.IMG | Commandline: fastboot flash boot boot.img
Flash BinDroid.zip
Reboot

Are you able to get into fastboot mode? if yes, you could go into ruu mode and flash your stock firmware, iirc the ruu zip only has to be on your computer.
anyway, this seems to be very odd tho... maybe you should wait for some expert to reply,because my knowlegde is kinda limited also if i remember correctly, there is one guy on this forum, that offers free unbrick support via chat...

HTC ONE stuck on recovery

Hi,
I hvae HTC ONE after trying to install custom rom and they didn't work (status 7) but now I can't load the system it automatically boot into recovery mode, also I can't factory rest in fastboot menu. plz help
Thread moved.
You have to download a custom rom like Viper or ARHD. Notice that you have to get the right recovery to flash diffrent roms. When using ARHD you have to use TRWP 2.6.3.3 recovery!
So make sure you are using the right recovery.
Some custom roms need to flash the boot.img via command prompt / terminal

Unlock the bootloadee again with a new unlock.bin
So you have to redo the process at http://www.htcdev.com/bootloader/
You have to use the new unlock.bin that you will receive from htcdev

TWRP Recovery 3.0.2-1 Official for OnePlus3

fastboot flash recovery twrp.img
Is only fastboot img or can it be flashed true twrp
I flashed from another twrp, after reboot i can not enter recovery any more.
Any ideas?

I think that after flashing you have to reboot recovery instead of rebooting system

Happened to me, too. Flashed via fastboot, forced a reboot, booted to recovery, and (I think after entering my encryption password) it wiped the /data partition. Glad I had a TWRP backup from earlier in the day. :/

Probably not, the official TWRP for the 5X and 6P still need security removed before backup. But it doesn't hurt to try!

[Help] Bootloop after unlocking Mi 9T PRO

Hi, thanks for reading:
I own a Mi 9T PRO 128GB.
After waiting for a week to unlock, I was able to do so.
Once I unlocked my device I tried to flash TWRP. I flashed a few until I found mauronofrio's TWRP.
Once I entered TWRP I couldn't read my data partitition so I selected Format inside Wipe option.
Now I'm stucked at fastboot logo!
I've tried to manually flash the official ROM I was using (raphael_eea_global_images_V10.3.4.0.PFKEUXM_20190923.0000.00_9.0_eea_65ad59b1cb) manually using fastboot.
Now I have original recovery, but it still won't boot. It just keeps resetting to Miui Unlocked screen.
Please, help me.

I don't have the answer, but don't sweat it for now. If your bootloader is still unlocked and you gave access to fastboot. There is a way to recover.

I'm going to follow these steps:
Flashing Recovery ROMs using XiaomiADB
Download and unzip XiaomiADB from here.
Download the Recovery ROM you want to flash from here.
Enter MiRecovery by holding power and volume up simultaneously for 5-10 seconds, then select the third option (Connect with MiAssistant / 连接小米助手).
Connect the device to your PC and open a command prompt in the unzipped folder by typing cmd into the address bar and hitting enter.
Type xiaomiadb sideload_miui into the command prompt, then drag and drop the downloaded ZIP on the command prompt window and hit Enter.
Wait until the installation finishes.
Disconnect the device and wait for it to boot in.
The first boot may take up to 15 minutes.
Wish me luck

Hi!
I'm stuck in the exact same spot at OP (stuck in fastboot loop).
I'm unsure how to put roms on the phone, or any data for that matter.
I was in twrp, then i disabled MTP and rebooted, now i can't get back to twrp. When i flash twrp again, it does not show up, instead goes to fastboot no matter the button combination.
Could you or someone please provide me some help. I'm very new to this process and am afraid i've bricked my phone.
Thank you!
I was unlocking bootloader and now 15 minutes I only see mi logo and moving dots above android.
Is this normal and I must wait more or is this soft brick?
