Anyone know what's going on here? Any general tips?
you have to reflash a recovery

[Q] Why is my flash from soft brick not working?

Booting normally and recovery takes me to a white screen. I can only enter odin download so i re-partitioned and flashed the stock rom. This completes successfully however booting normally or recovery still takes me to white screen with only odin download working.
Is this motherboard or is this fixable?

Thread Modes Teno W3 won't boot to TWRP recovery after flashing

I flashed TWRP on my tecno W3 using sp flash tool, after it went successfully, i powered my phone into recovery mode with the right combination of keys. But it wont boot into anything, but when i power it into normal mode, it goes successfully..and then i switch off and boot into recovery mode with the same combination of keys i used after flashing, it end up into stock recovery. It's like my phone is locked from booting into custom recoveries(even after unlocking the bootloader), and then it overwrites the custom recovery with stock after booting into normal mode. Is there any way i can get my phone to accept custom recoveries, and i have no root thats why im trying to flash a custom recovery first.
Also: I tried to use adb to boot into fastboot mode and boot into the same custom recovery i have by the command: fastboot boot <filename.img here>..but i didnt boot into anything, it just boot normally like i restarted my phone. I even tried to flash the img file in fastboot mode and then boot up with the fastboot command mentioned above, but it just boots into normal mode.

Did you install SU/Magisk after you flashed TWRP?This can usually prevent this issue.

No, just TWRP. It flashed successfully, but the phone won't boot to anything, and when i force it to boot into recovery mode after flashing a custom recovery, it doesn't do anything, it just stucks in the Hi logo with a red exclamation mark...and i usually have to press the volume + and power button to get to the menu, but the menu for the custom recovery i just flashed fails to pop up. After that, i boot into normal, and it overwrites the custom with stock recovery again (can tell from when i boot into recovery again after booting into normal by bringing up stock recovery)..
I used the recovery i ported myself using calvik image kitchen tool.
My phone does it too. The TWRP asks me if it has to be reinstalled, if default recovery is taking its place. Flash SU or magisk in your recovery immediately after TWRP.

Can't boot instantly into recovery mode after flashing twrp with odin

Hello guys.
Like the title says, I can't boot directly into recovery mode after flashing twrp. I know the combination for booting into recovery mode but it automatically forces it to boot normally. I have to power off my phone after it starts normally to boot into recovery mode. But the problem is that the twrp disappears after it starts normally after the flash because u have to get instantly into the recovery mode (I think.) so it doesn't reset.
Modelnumber: SM-A510F
It worked at first, but there was also a problem with the recovery system because it always showed "No Command". I didn't use the latest version of odin and twrp. I only followed a guide with download links for this model. The odin flash succeded btw. I hope for some help here.
Thanks.
