Can someone point me to a procedure to install a custom recovery. I'm currently on the stock recovery, have downloaded a CWM .img file, but don't know how to "flash" it using the stock recovery. Or is that not the way it's done at all? Thanks for the assistance.
Hi,
[GUIDE] Nexus 5 - How to Unlock Bootloader, Install Custom Recovery and Root
You need to flash it in fastboot. Boot into the boot loader and, fastboot flash recovery recovery.img. where recovery.img is the cwm image file
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.
I recently tried to install multirom but it kinda messed up, Now I can't either do fastboot boot recovery.img or fastboot flash recovery.img cause none of them works. I also tried to recover stock firmware but it didn't help. any help is appreciated.
I can boot into stock recovery via fastboot boot recovery.img but cannot boot a twrp or cwm.
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
I just installed Lineage, and it worked, installed it via fastboot boot recovery...
After installation, I wanted to install the recovery too, so i run the command fastboot flash recovery
Then I try it, and it's working. TWRP 3.0.2.0.
But, after reboot, it's booting directly to TWRP. Again and again. can't boot normally to system...
Anyone have a solution ?
Thank you

It has to be done in this order:
fastboot flash twrp.img
boot TWRP
install LOS zip
