How to stop Stock ROM overwriting the Custom Recovery? - Oppo Realme 3 Questions & Answers

I was trying to flash a Custom Recovery(TWRP) on my Friend's phone(Realme 3) It was officialy supported by TWRP and was listed on their website so I downloaded the Custom Recovery. Then I unlocked the bootloader of his phone but yes a strange thing happened there after it asked for pressing the volume button to be pressed it unlocked the bootloader but after that there was option "Select boot type"(Not sure what it said). It had three options Boot to Bootloader, Boot to recovery and last Normal boot and also there was a arrow on the bootloader option. And there were some instructions something like volume up for select and volume down to move. But I tried every button but the arrow was stuck on the bootloader option. So I connected it to my device and used the "fastboot reboot" command to restart the device after restarting at the realme logo it was saying "You are unlocked you cannot be trusted" But after it booted normally and the phone was Factory Reset. After this in the Developer options the OEM unlocking was grayed out saying Bootloader is unlocked. Ok so we were successful in unlocking the bootloader. After that I pasted the twrp img file in the platform tools directory and put the command adb reboot bootloader and after the device was in bootloader I used the command fastboot flash recovery name.img to flash the recovery. It said sending and then writing in my terminal after that I used the command fastboot reboot and the the key combinations(power+volume down) for the device which used to get into recovery for that phone but this time instead of going into recovery it was in the bootloader. So again I tried fastboot reboot command and this pressing the power+volume up but the phone booted normally so this time I tries adb reboot recovery but it booted into stock recovery so again I tried flashing the recovery and tried using fastboot reboot recovery but it didn't work. And yes I know that after flashing the custom recovery the phone should first boot into the recovery but as I said neither the key combinations nor the fastboot reboot recovery command so what can I do to prevent the system from overwriting? PS: Sorry for long paragraph...

Need some advice....

I tried to root my phone and followed all steps until it asked to boot into the custom recovery and that only displayed a blackscreen and if I tap on the screen the phone vibrated. I cannot boot into bootloader as the phone just automatically tries to enter recovery with blackscreen.
Hold all buttons the phone boots normally and can use the phone as usual.
I've tried to use the adb and fastboot cmds to restore and factory reset but just reboots and tries to enter recovery with the blackscreen.
My device is htc_a51ul if that helps.
Thanks,
Phatzy
Tighten two volume buttons and the power button when you see a black screen and holding down the volume- and power button that would go to zagruzchik.Telefon must be connected to kompyuteru.Esli got to go to the boot loader, boot into download sistemu.Esli not work then you have forgiven stock rekaveri of loader. https://yadi.sk/d/nWnRAChBnEtxG
I think you have flashed a wrong recovery ,first thing to do now is flash stock recovery and whether if it is working fine if so then flash the proper version of twrp 2.8.7.0 is recommended and see if it works
I had the same issue when I first flashed twrp on lollipop but then I did the above and now everything is fine.
while its on the blackscreen only adb commands work. If i try fastboot commands its just waiting for device and phone dont respond. I cannot get into bootloader at all with volume keys or with adb command.
Many thanks for suggestions.
Ok I have now managed to get bootloader back and I can now enter the stock recovery but when I enter recovery it has a red triangle. Is there anyway to remove this?
Thanks.

Did you hold the volume down button + power button to get to recovery mode manually right after flashing?

If you have successfully unlocked the bootloader, you'll get a bootloader unlocked warning every time you boot. On the warning screen, click either of the volume buttons and you'll be redirected to a bootup menu. From there, you can select "boot to recovery" using the volume rocker and power button.
Alternatively, enable "advanced reboot" in developer options and reboot to recovery from the main OS power menu.
If these don't work, reflash TWRP using fastboot. Make sure that you're using at least version 3.0.3-1, best to use 3.0.4-1.
Tried manually reboot into recovery but it just reboots,
I can sucessfully unlock as i have the warning on boot, but there if i go to the menu and press for recovery it just reboots, tried several tipes of recovery TWRP imgs
Any help greatly wanted
Download this version of TWRP (jcadduono's 4.0.3-1). Rename the file to something like twrp.img.
1) Make sure adb/fastboot is working on your computer (if you've already unlocked the bootloader, then I am assuming it is).
2) Put your phone into fastboot mode and connect it to your computer. Open a command prompt where you can access fastboot.
3) Put the twrp.img file to the same folder where you opened your command prompt.
3) Enter
Code:
fastboot devices
in fastboot and make sure your phone shows up with its serial number.
4) Enter
Code:
fastboot erase recovery
to erase your current recovery
5) Enter
Code:
fastboot flash recovery [B]twrp.img[/B]
, where twrp.img is whatever you named your twrp file.
6) Enter
Code:
fastboot reboot
to reboot into your main system. You can either reboot then use advanced startup to enter recovery, or press a volume button at the bootloader warning page to boot directly to recovery.

Sometimes it helps to use fastboot to boot the image directly after you flash it. This ensures you get into recovery since it loads it off your computer.
It should then work normally afterwards

Firmware Update

Recently i've unlocked my bootloader in order to install a custom ROM. Everything went fine until i flashed twrp image. Whenever i try to get into recovery ( power+vol up ) it pops a window saying "Firmware Update". In the cmd log it says that recovery flashed successfully. I've enabled OEM unlocking and adb in the dev settings. BL is unlocked. Device was connected to the PC at the moment of flashing ( obviously ) aswell as at the moment of entering the recovery.
Please help me find a solution, thanks.
fastboot flash recovery twrp.img and then enter recovery by holding power + vol down (to get into bootloader) and then choose recovery mode and enter.
Exactly what Przemcio said. Flash the TWRP from your PC using fastboot, and then boot into it from the bootloader. I never use Pwr+Vol_Up, I always use Pwr+Vol_Dn to get into whatever I want.
Vol up is for LG Flash tools only.
I flash recovery via fastboot. Press vol down

yeah, it's orange encrypted and now i have to decrypt.
i just can't bypass this message "your device cannot be checked for corruption". Whenever i try to choose the recovery this pops up and then phone reboots. I flashed stock google image for nexus 5x and it didn't solve the issue, nor fomratting data thru adb.

Unable to boot into TWRP

Hello everyone,
I really need help from you guys.
Yesterday I successfully flashed LineageOS 17 but unfortunately I forgot to flash Gapps using TWRP. I booted into system and then only few seconds afterwards I realized that I forgot to flash Gapps.
Then I tried to boot into recovery but the problem is I got forced to boot into stock recovery instead of the TWRP that I managed to flash in the first place. After that I tried to re flash the TWRP but then I got booted into the stock recovery everytime. Here is what I did and still failed to boot into TWRP:
1. adb reboot bootloader
FastBoot Mode
PRODUCT_NAME - ZS620KL
BOOTLOADER VERSION - WW_90.11.162.72
SERIAL NUMBER - J8AZB760J064ADX
SECURE BOOT - yes
ACTIVE SLOT - b
DEVICE STATE - unlocked
2. fastboot --set-active=a
3. fastboot reboot bootloader
4. fastboot flash boot boot.img
5. disconnected my usb cable
6. press volume keys to change the START to RECOVERY MODE
7. long press power key
8. press volume down and power key at the same time until Bootloader Warning Message appear
9. and then "POWERED BY android" appear
10. my phone is now booted into STOCK RECOVERY.
Please help me guys
I really need to install Gapps

Can't boot to recovery

Hello guys,
I have a Ginko device. It started to act weird, as if the volume down button was held down at all times. I took it to some shop and they told me it's most likely software and not hardware, and to try and flash a new ROM.
Now, I believe he was talking out of his ass. Rebooting the phone automatically puts it into fastboot because of the volume- button being broken. If it was a software issue this would not happen, I believe.
Whatever, I decided to try and flash a ROM just because maybe if I have root I will be able to block that button from working somehow.
The issue is, I can't boot into TWRP.
I unlocked the phone through Xiaomi and downloaded TWRP for Ginko. I did the `fastboot flash recovery twrp.img` thing and it works fine, but after that the command to reboot it to recovery `fastboot boot twrp.img` does not work. The fastboot image goes black for .1s then it shows the fastboot image again. Nothing happens. If I run the command again it takes a few seconds shoing "booting..." then the phone reboots to SYSTEM and an error shows on the CMD saying "FAILED (status read failed (Too many links))".
The only way I've found to boot to recovery is by using `adb reboot recovery` but that needs me to boot into system, which means TWRP is erased and the default recovery comes up.
If I reboot the phone the only way to go into system is by holding volume+, as it seems to counter the broken volume- button... But that means I can't boot to recovery, no matter how many times I try.
So I have no idea what to do.

Did you also try to flash recovery as you did before but right after that booting directly into recovery using hw buttons (vol- and pwr button till boot splash appears) from fastboot?

to prevent twrp to be erased flash vbmeta (attached) using :
fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img
i suggest you use OrangeFox and enable "aggresive stock recovery deactivation" in settings
This is a hardware problem and it's better to replace it
you can disable that button (while on Android) using xposed edge by setting "none" to click and long clic (need root + lsposed or edxposed)
