[Q] A500 can't boot in recovery - Acer Iconia A500

Yesterday I installed unlocked bootloader v8, TWRP recovery and rooted my device. But now I can't boot in recovery, when I try bootloader says: "booting recovery kernel image", next thing I see a android logo with a red caution mark coming out of his belly.
Can someone help me? What am I doing wrong?

Because you still have the stock android recovery installed.
And that's more than likely because you probably restarted your tab, under a stock ICS rom, and didn't delete the boot.recovery.p and/or install-recovery.sh files in the System directory. In this case, every time you boot into the OS, it overwrites your current custom recovery, and installs the stock recovery.
Delete those 2 files, then flash your custom recovery.

[Q] Flashing TWRP over RA recovery

As the title says, GooMananger appears to download and notifies "recovery successfully installed!" but on reboot recovery, its still RA-Iconia-3.17. I've done the same process more than 5 times with the same result.
I have tried to install the image via fastboot, but on reboot, again, its RA recovery.
Can anyone lend a hand?

Can't boot into recovery mode

I have my Fiance's XT907. I rooted and unlocked the bootloader with no problem but when I try to install a ROM or just even boot into recovery, I get the red triangle and android with his stomach open. I tried using ROM Toolbox, ROM Manager, Goo, and every time I try to flash TWRP in ROM Toolbox it gives me an illegal instruction error. I tried flashing it through fastboot and it flashed successfully, but still can't boot into recovery. The red triangle stays on the screen for maybe a minute, then the unlocked bootloader message appears and reboots normally. I don't get it. What do I need to do?
You have to flash your recovery in fastboot

Tried Installing CynagenMod 13, Stuck In a weird Recovery Bootloop

Hello Guys,
So i managed to fix my previous error. Now I'm at the end almost. I'm installing CynagenMod 13 on my N9005. I installed ClockworkMod Recovery, I think. I say I think because when i try to boot into it I get the below message.
"Recovery Booting"
"Set Recovery Bit : recovery"
Then it goes black and vibrates twice and boots normally.
I have the CynagenMod in a zip on my SD and the guide i am following refers to the ClockworkMod Recovery menu. The normal Recovery menu loads fine, ClockworkMod Recovery doesn't seem to load. Can i use the normal Recovery or does anyone know a way of getting ClockworkMod Recovery to work?
Root is not required to flash a custom rom or recovery.
Try flashing twrp and then flashing a rom from twrp.

Boot into twrp by pressing VOL_UP+VOL_DOWN along with POWER_KEY and release the power key once the lenovo logo shows up.
Then flash any new rom.
Thanks sasukay it's working, I was thinking my phone is dead

Device Boot Looping/Soft Brick

I decided to unlock the bootloader so that i could flash TWRP recovery but after unlocking the bootloader on my device, it has been stuck on the logo screen with "powered by android" under it. I have tried using fastboot to clear userdata & cache but that just leads to my phone again being stuck on the logo screen. The device also can't boot into recovery. When I chose to power off in fastboot it causes me to be stuck on the logo screen. Any help is appreciated I am on android oreo btw
Did you try a back to stock zip? go to fastboot and run flash-all.bat, while your device is plugged in ofcourse.

Let me guess.
You unlocked the boot loader and flashed TWRP and now you are looping, right?
There is no compatible TWRP that is compatible with Oreo on this phone.
You cannot leave TWRP installed. You can only install it along enough to get the recovery to boot.
You then must flash the stock boot image.
I had this problem tonight also. In my case I suspect it had to do with the install of magisk in which I checked both boxes and patched the bootloader. on reboot I was stuck on boot. Just wanted to add my solution. I got the pie back to stock zip here https://forum.xda-developers.com/essential-phone/development/stock-7-1-1-nmj20d-t3701681 then I put it into the adb folder and ran the flashall.bat script. I tried the no wipe one and it saved my information. very happy I didnt have to resetup my phone in the end.
did you remember to flash a stock boot.img before flashing magisk (to clear TWRP?)
