[Q] Using fastboot to boot directly into Recovery? - G 2014 Q&A, Help & Troubleshooting

Hi, my device (euro 8gb dual sim, 5.0.2 ota updated) got crazy last night with lots of FC and unresponsive behaviour.
It boots into system but even screen is off most of time. I can only access power menu before FCs appear and screen goes off.
I tried to boot into recovery but it is not possible since droid on its backs never appears. (see this thread http://forum.xda-developers.com/mot...orola-moto-g-2014-t2994311/page2#post59096800)
Is there any command to launch recovery menu via fastboot?
Furthermore, since I can access fastboot menu, I saw a "Factory" option near "Recovery" option. What is it for?
PD: If Recovery is really not accesible to perform a factory reset... Maybe flashing recovery.img for my model and firm (5.0.2) could help? Or is it better to flash a full 5.0.2 firm?
Thanks!!

[Q] Can't boot into recovery or erase recovery (TRIED ERASING CACHE)

Hi I am trying to work through the process of rooting my HTC One.
I have some experience with android as I've rooted three different phones now, the One is the only one giving me trouble :/
So I got the bootloader unlocked via the HTC Dev method, and now I'm trying to get recovery to work. I've flashed CWM, CWMT, and TWRP, and no matter which I try I can't boot into recovery via "adb reboot recovery" or via the HBOOT menu. When I try the phone just goes through a regular reboot. I can't use ROM Manager to do it either naturally since I don't have root yet (need recovery to install SuperSU).
However ROM Manager does show I have CWM and TWRP installed (both? weird) so I tried to start over by doing "fastboot erase recovery" but it says
FAILED: (remote: not allowed)
I tried "fastboot erase cache" before and after flashing a recovery and nothing at all changes.
Any ideas? Could I have missed something really simple and stupid? I'm pulling all my hair out trying to figure this out.
I heard some people got it to work by flashing the recovery to the boot partition, but until I get assurance that isn't a terrible horrible idea (like it seems) I don't want to try that.
EDIT: yes, the "fast boot" option in the power menu is already disabled.
I had the same issue. Solved it by disabling the fast boot option within the OS. Under power options.
Worth a shot.

Thanks for the reply but that option is already disabled
I was facing the same problem, however, what I did was turn on fast boot under settings right after I flashed the recovery.
Then, I rebooted back into the bootloader and I now had ***TAMPERED*** at the top of my screen. I afterwards selected reboot into recovery and bam, I now had TWRP on my phone.

Just tried that, didn't work
Also why would you have TAMPERED at the top? Did you change anything else to get that like flash a different HBOOT or fastboot or something?
I'm about to throw this thing out the window -___-
SOLVED
Hallelujah, I got it!
I did nothing differently, but eventually it worked...very weird, but at least I got it! The final iteration to get it working was this:
1. Turn off fast boot option in power menu
2. Boot into bootloader via power menu, then power + vol down
3. go into fastboot
4. from a cmd window, fastboot flash recovery recovery.img
5. fastboot erase cache
6. from the menu, boot into recovery
7. phone boots to the OS instead of recovery
8. boot back into the bootloader via power menu, power + vol down
9. TAMPERED shows up, boot into recovery and it works!
note that i never used adb reboot recovery or adb reboot bootloader, idk if that matters, but I did everything from the phone.
thanks for all your help!
For what it's worth, I use ROM Toolbox's Reboot to recovery option and it works. Though I can see where you'd need to boot to recovery from startup.

Recovery doesn't come up -- Mismatched Partition

Moto X 1095 with 24.11.18 6.0 update doesn't boot into recovery. Everytime I try to fastboot flash a recovery, it prompts a mismatched partition.
If I try to reboot into recovery, it will give me a blank, black screen.
Any advice would be appreciated.. I am not sure what to do. No one has a solution to this. I've tried to look for a factory recovery.img but no where to be found.
Can I downgrade to 5.1 using the Motorola Factory Image ? If so, how?
I have a similar problem
Does the black screen have the Android robot with an exclamation mark in it? If so, that's the stock Recovery. Press Power + Vol Up, and you should be able to access it.
When flashing a custom Recovery, make sure that after issuing "fastboot reboot" you don't let the phone boot into system, otherwise you'll end up with the stock Recovery again. After the reboot, you should access the bootloader again and enter Recovery for the custom Recovery to take place.

HELP I deleted OS via twrp

I need help. I deleted/wiped in advanced mode in twrp the system and now I have No OS installed. I don't kow what to do now the phone does not bood except into twrp.
Use NOST
Sent from my NB1 using XDA Labs
After hours of "work" I have my phone running again. I was able to get the phone run stock recovery again and then was easy to just flash the oreo zip.
well good to know you solved the problem.
but just in case keep your phone bootloader critical unlocked so you can use NOST if you face such problems again.
Just happened again. I wanted to put twrp img back on the phone and as it reboots... its stuck on "Powered by Android". I cannot flash or do anything since its stuck and does not turn off. I tried all combinations of volume/power button and hold them for minutes... just does not turn off. So its not recognized by NOST or anything. Now I am really screwed as it seems...

I am at such condition too... how long battery lasts? I think it's possible to wait for the phone to fully discharge and then we may have access to recovery. right?

If you tried to "fastboot boot" the TWRP image: thats "normal", fastboot boot is broken on every firmware since august. You have to flash TWRP to your active boot partition to boot it. However, at least for me, when being stuck in that screen I can still use "fastboot reboot" or "fastboot reboot-bootloader" to get the phone back in a working state.
Also, if you try to flash TWRP to your active boot: Please don't flash the image from the official site, since that is unable to boot into the system normally. Use my recompiled generic TWRP boot image that you can flash, regardless of security patch version: https://forum.xda-developers.com/nokia-8/development/twrp-data-decryption-android-9-t3911411
If you did not fastboot boot an image: Hold down volume up, volume down and power for multiple minutes until the phone turns off. Then hold volume down while connecting the phone to a computer through USB, and it will start into fastboot mode. Then just revert whatever you changed and reflash the stock image.

It turns out that there was Pie on my partition B and I was not aware of that. Booting into TWRP wasn't working, so I flashed it and then factory reset system. And it broke the phone.
Now I tried to boot the TWRP from slot B and rebooted partition A. Now the phone is up... Thanks
Where can I find the appropriate stock boot image for my partition B? and should I fastboot it with boot_b command or what?

Motoe5(Nora) Custom recovery not installing

I tried to install twrp in my Moto e5 (XT1944-6) device. I flashed the latest twrp image using adb platform tools. But when I switched to recovery mode, the TWRP logo appeared for a long time.
Instead of TWRP UI, a screen came called "Mount". It told me to enter a password,and a keyboard was open. There were 2 options " cancel" and "change language".
But I wasn’t able to do anything. Touches were not working. After a few moments the screen slept.
When I clicked the power button, a complete WHITE SCREEN appeared.
I was trying to go to fastboot mode, but it was coming to recovery mode every time. After a few try, somehow I switched to fastboot mode & restart my device.
Again I went to recovery mode, but TWRP wasn’t there. It was the stock recovery and still it is. Please help!

stock overwrites the recovery, you must change the rom to avoid it, and the password thing is called encryption and to remove it you must hit cancel, wipe format data and write yes [THAT WILL ERASE ALL YOUR DATA]

Unable to enter Recovery mode after reboot from twrp or stock recovery.

Moin,
My phone was one day suddenly unable to boot into system nor Recovery, but could still enter fastboot.
Took me a while to figure out that USB Hubs let flash attempts fail too. (you can watch the drama in my older posts)
Now i was able to flash System back into a workable state and it looks like that recovery is also successful flashed.
BUT...i can enter recovery only ONCE per Vol - and Power on Button.
i have NO OTHER WAY to enter Recovery at all. i have no reboot option in system (LOS 18.1).
In fastboot/adb command and after one succsesfull reboot per keys, it always stuck after the Sony logo into a black screen. i then have to restart it into system with Vol+ and Power (one vibration) or shut down with vol+ and power for 6 seconds (three vibration) to get it either into fastboot (Vol+ and USB connect) or system again. then i have to flash it again to get into TWRP once. i tryed the latest twrp version (3.7.0) and one older version (3.3.1) that had once worked until the phone broke.
Any idea what is going wrong here. i have already try to completly wipe everything from the phone and try to fix SEL Linux in twrp. nothing seems to work. Did i miss something?
/€: Now it is again in the full broken state. recovery nor System won't boot anymore and end in a black screen.
/€²: Found the Problem: my lilca zip was polluted with altered files i forgot about.
