I have been looking to Root my A510 and drop KitKat on it, but I am stuck trying to install the recovey,img
Steps completed so far:
Bootloader unlocked
adb reboot-bootloader
fastboot oem unlock
fastboot reboot​
Obtained the recovery image 6.0.4.5
Loaded recovery image
adb reboot bootloader
fastboot flash recovery c:\AndroidRootTablet\recovery.img
fastboot reboot (holding volume down)​
Just boots up normally... I can get into the stock recovery using adb reboot recovery, but I see no way to add the recovery image...
A510 version is 4.1.2
I probably have this out of order, but I tried to root the tablet first, but that didn't work either. A few questions:
-- Do I need root before installing the recovery.img?
-- What is the current recommendation for rooting the A510?
This is what I tried to use for rooting:

No need to root before flashing a recovery
You have to reboot in recovery directly after flashing it via fastboot and flash the zip "disable stock recovery"
With a JB bootloader you have to : Hold Volume- (**), and when vibrate, release it and hold Volume+(*) until the recovery load
If you reboot in Normal mode, the Acer ROM will erase the recovery.
Check the initial CWM thread with it's installation guide: http://forum.xda-developers.com/showthread.php?t=1866378
Could be applied with any version of custom recovery
A510 Updated to KitKat
Thank you sir for you help. That hit the spot. I greatly appreciate the work you are doing with the A510.
Hello! I've tried to root my phone (Moto G XT1541 Europe 1GB) but failed. I got an error when trying to flash the custom recovery. Unfortunately, it has overwritten the stock recovery and it didn't install. So, now I have a phone without recovery and I can't do a factory reset because of that (I think).
So, this is my question: how can I re install the default Android 6.0 recovery mode for my phone?
Also, my phone boots automatically on bootloader mode and I can't re-lock the bootloader because I can't flash anymore either; I got an error because the pre flash validation failed when trying to flash with adb fastboot, but this is minimal issues that doesn't really bother me, but they could be helpful and if someone knows how to get rid of them, I want to know!
I hope someone will help me!

The bootloader cannot be relocked in the Moto G 2015, the best you can do is hide the warning screen. Find the stock image and fastboot flash the recovery from there, or better yet, flash the entire image so you are in a known working state
If you are in Pre-Flash validation, you do not have the correct image for your device... I suggest you post in the "How to flash factory images" thread about returning to stock, if it is possible. You MUST factory default before flashing factory images, if you can't, try 'fastboot erase userdata' and try again.
Flash latest twrp via fastboot and reboot into recovery ,
don't reboot into system,
reboot into recovery manually, then you can enter twrp recovery and can flash supersu 2.62.3.
when you just reboot after flash twrp and reboot system erase custom recovery and save stock recovery, so don't enter fastboot reboot, enter fastboot reboot recovery after flash recovery via pc.
Rename twrp recovery as only twrp in fastboot folder in your pc , not as twrp.img,
But cmd as fastboot flash recovery twrp.img , then no errors ( are you unlocked bootloader ?)

Hey! Thank you! I've been able to flash the TWRP recovery and now I can do a factory reset (and also send sms, which I couldn't do anymore for some reason).
I still have the issue where the bootloader screen appears everytime I turn my phone on, and I still can't re lock my device because I can't flash anything either. I've recovered all of my data, so I think I'm going to stick with that for a moment but maybe I'll try what you said some day.
Again, really thank you for helping me!

Now I understand why my flashing TWRP did not take. I simply rebooted to system and still have stock recovery installed. I was successful booting twrp via fastboot and successfully flashed supersu 2.62.3. Is this step in listed in any faq? I must have missed it.
So after flashing TWRP, do you then power down device prior to manually booting to recovery?

Don't power down, already you are in fastboot mode, you can just enter recovery from that. I forget the reference, but i will search and post.

I get this from twrp official page
Note many devices will replace your custom recovery automatically during first boot. To prevent this, use Google to find the proper key combo to enter recovery. After typing fastboot reboot, hold the key combo and boot to TWRP. Once TWRP is booted, TWRP will patch the stock ROM to prevent the stock ROM from replacing TWRP. If you don't follow this step, you will have to repeat the install.
In our phone press simultaneously volume down + power button to enter recovery.
Hello guys, I don't have no more idea to fix it.
Today I unlocked my bootloader, all was Stock and no Root. I want try This Lineage OS 15 and is mandatory flash the TWRP to install the Rom.
OK, I unlocked my bootloader and downloaded TWRP Dual Version, extracted the img file from zip and flashed in fastboot mode like the tutorial says: fastboot flash FOTAKernel recovery.img
the flash was donne fine but I can't enter in recovery mode, I tryed in adb adb reboot recovery but isn't work too, anyone have an idea?
Attached some images to explain...
Sorry for my bad english.
Forget, xkeita give me a tip and I can now enter in recovery, I suppose that the Stock kernel don't boot it, just flashed the Kernel rom that I want to use and in sequence, flahsed the TWRP and it worked.
Sumary:
1. I extracted the Boot.img from ROM ZIP and flashed it with: fastboot flash boot boot.img
2. I Extracted the TWRP IMG and flashed it with: fastboot flash FOTAKernel recovery.img
reboot the phone, and turn on pressing vol key down ultil boot in TWRP.
Maybe this is usual to someone.
Thanks a lot @xkeita and @serajr for all the help and suport, I Learned a lot, thanks.
Moderators, can Lock this tread please....

i managed to flash twrp via fastboot, with command:
fastboot flash recovery recovery.img
and then i applied:
fastboot boot recovery
and it booted into twrp (yay), but when i try to reboot it into system (or poweroff, and on), it boots into twrp. succesfully managed to replace stock recovery, but now i cant go into system. i got backup of system, but i don't know how to boot into system now.
phone is Allview Viva H801
I don't know how i can get into fastboot now via twrp. Is there way to communicate with twrp via PC. because twrp terminal , closes keyboard when i press key 'b', which makes it impossible to type any command (to get into fastboot )
can i fix this via twrp as i cant go into bootloader

TWRP don't have reboot bootloader option!?
Re-flash Stock ROM.
Thread closed as OP removed the content from the opening post.
trying to install a rom to my realme Q, through fastboot I installed a TWRP recovery that left me in bootloop and by mistake with the same fastboot I deactivated the bootloader and now I can no longer enter ADB mode to connect I have installed the recovery or the boot from stock, what can I do to reinstall at least the recovery or activate the bootloader again and thus be able to install a recovery and a rom again through fastboot.
