I followed @neo.ank's all-in-one guide and am having trouble flashing a custom recovery (twrp-2.7.1.0-condor.img). My bootloader is unlocked and fastboot flash recovery recovery.img works without problems:
Code:
C:\Folder>fastboot flash recovery recovery.img
target reported max download size of 268435456 bytes
sending 'recovery' (7300 KB)...
OKAY [ 0.235s]
writing 'recovery'...
OKAY [ 0.232s]
finished. total time: 0.471s
I then use my volume up and down buttons to select "Recovery mode," which returns me to the bootloader (the logs say "Boot up failed"). So I boot up into Android and adb reboot recovery, which works.
Now I see the "dead robot" with "No command." Huh, oh well, pressing power and volume up shows the "Android system recovery." A step ahead, but where is TWRP?
I think the guide I followed may be outdated. Has anyone had success using it to flash recovery on the 2015 Moto E?
TL;DR: Successfully flashed TWRP recovery, but it seemingly disappeared when trying to boot into it.
Fixed. I used the wrong recovery.img. Using the surnia recovery instead of condor works: http://forum.xda-developers.com/devdb/project/dl/?id=11449

Hi, all.
I was messing around with Android Tweaker 2, zipaligning my apps, performing vague system tweaks and the like, when I rebooted my phone for the changes to take effect; however, the phone booted up, finished the booting animation, and where the home screen should be showing up only showed a black screen. From there I can only reboot again, reboot into STOCK recovery, or reboot into fastboot, which has limited function in an Asus device (inability to flash unsigned custom recovery images, inability to flash rom images, stock firmware images are unavailable ANYWHERE, etc.) My device WAS rooted, however, I did a factory reset from the stock recovery in hopes that the problem would be resolved, so I'm not sure if root access was retained. I've tried a lot of things, but what I need is access to adb to push some files, or just figure out what the hell happened to the device.
Any ideas? Thanks in advance.
Details:
Asus Padfone X [4.4.2 stock rom]
WAS rooted
LOCKED bootloader
STOCK recovery
Fastboot is basically useless, given the "safeguards" Asus has implemented
Read the CM12.1 for instructions on unlocking bootloader , there are instructions on booting from custom recovery using fastboot from there you can adb push the files to your phone as posted in the Nandroid Stock backup thread and install using TWRP.

Thanks for the advice.
I have consulted the CM12.1 thread, and I see the instructions, the first step of which is to "boot into CWM, CMRecovery, or TWRP." However, I do not have any of these custom recoveries flashed on my Padfone X. Is there a way I can boot custom recovery off an external microsd or something?
Note: upon attempting the "fastboot flash recovery CMrecovery.img" command, the cmd window returns the following:
Code:
target reported max download size of 1879048192 bytes
sending 'recovery' <11220 KB>...
OKAY [ 0.438s ]
writing 'recovery'...
FAILED <remote: can't flash unsigned image>
finished. total time: 0.444s
EDIT: Problem has been resolved, used
Code:
fastboot boot twrp.img
and restored stock.

Glad I was able to point you into the right direction.
Hi all,
I have an LG G5 H850. I'm trying to install TWRP using ADB. I've had it previously and it worked fine. I'm pretty sure the bootloader is unlocked. Anyway, when I do "fastboot flash recovery twrp-3.1.1.1-0-h850.img" I get the following output:
target reported max download size of 536870912 bytes
sending 'recovery' (19076 KB)...
OKAY [ 0.431s]
writing 'recovery'...
OKAY [ 0.345s]
finished. total time: 0.781s
To me, that looks as though thats worked fine. Now when I try fastboot boot twrp-3.1.1.1-0-h850.img I get the following:
downloading 'boot.img'...
OKAY [ 0.432s]
booting...
FAILED (remote: unknown command)
finished. total time: 0.456s
Has anyone got any ideas on this?
Same here
I am having the same problem, please help
Had this issue a while back. I resorted to doing complete flash with LGUP to the latest version and then it worked. I had been messing around with various ROMS on different android versions.

Don't happen to know where I could get a rom that it would work with do you?
Managed to solve this. Flashed the TWRP image using fastboot flash recovery <img> via adb. Then I unplugged from USB, and got into recovery mode by doing power + volume down buttons and quickly release and repress ont he LG logo. Answered yes to both questions and got into TWRP.

That is the required way of doing it. You have to boot into recovery after flashing the recovery or it gets reset.
Hi,
Having a similar problem since trying to update my ROM ... and the Magisk install failed. Now I can only get to fastboot, can't get to recovery. And, tried this,
Code:
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp-3.1.1-0-h830.img
target reported max download size of 536870912 bytes
sending 'recovery' (18644 KB)...
OKAY [ 0.439s]

Help!?! ... and thanks!
Before:
I just unlocked the bootloader and installed a custom ROM (LineageOS 15.1: https://forum.xda-developers.com/huawei-y6/development/lineageos-15-1-huawei-y6-2018-t3832278) on my Huawei but it won't let me flash the TWRP from adb. I tried before flashing the custom ROM and also after but no progress. I tried with 'fastboot flash recovery recovery.img' as well as 'fastboot flash boot recovery.img' because I knew some smartphones include the recovery in the boot.img but I am always getting the same error:
Code:
fastboot flash recovery recovery.img
target reported max download size of 535822336 bytes
sending 'recovery' (16544 KB)...
OKAY [ 0.522s]
writing 'recovery'...
FAILED (remote: partition table doesn't exist)
finished. total time: 0.553s
I am not an expert but I understood that 'recovery' partition doesn't exist. I found some possible solutions online such as writing 'fastboot flash RECOVERY recovery.img' or 'fastboot flash erecovery recovery.img' (because Huawei calls the stock one 'erecovery') but they both gave me another error:
Code:
fastboot flash RECOVERY recovery.img
target reported max download size of 535822336 bytes
sending 'RECOVERY' (16544 KB)...
OKAY [ 0.522s]
writing 'RECOVERY'...
FAILED (remote: Command not allowed)
finished. total time: 0.528s
UPDATE: I found, maybe, the correct name of the recovery partition and it seems to work:
Code:
fastboot flash recovery_ramdisk twrp.img
< waiting for device >
target reported max download size of 535822336 bytes
sending 'recovery_ramdisk' (14026 KB)...
OKAY [ 0.443s]
writing 'recovery_ramdisk'...
OKAY [ 0.323s]
finished. total time: 0.767s
BUT it actually doesn't work properly because when I boot into recovery it boots the stock one. I tried other solutions found on the net like instantly unplug the phone after the flash and reboot it into recovery immediately but again it boots into stock one...
OTHER UPDATE: I managed to find and flash a TWRP that can boot up but it shows the internal storage 0MB not allowing me to install any .zip file. Because of that, I cannot install SuperSU to get root access.
I tried installing TWRP also with stock ROM but still showing 0MB because the phone is encrypted. To disable encryption I need to install the bluspark TWRP (As I found online), the problem is that bluspark won't boot and gets immediately overwritten by the stock ROM as it happened with the one I mentioned in the first update of the post.
Now I will try buying a microSD card and see if it shows right so that I can still flash .zip from the microSD card.
Now:
LATEST UPDATE: The SD card is working properly and I see it as around 60 GB instead of 64 but that's not the problem. I can see the .zip files I'd want to flash but when I try to do it it says me that it failed to mount every single partition and after some research I discovered that my Huawei has all the data encrypted. After other research I found that there are some TWRPs like blu_spark that could decrypt the data but every version I tried doesn't work and gets immediately overwritten by the stock recovery.
Does anyone know other methods to decrypt all the data on Huawei? Otherwise it's impossible to flash any .zip. Actually it flashes it but it fails to update the partitions state so the system doesn't recognize the changes.
Rooting Huawei is so difficult.. I will buy an OP5t as soon as I have the money XD.
Y6 2018 twrp
Any progress? I'm also looking for a version of TWRP that works with the Y6 2018.
Hi,
my Xperia Z2 (runs on Android 4.4.2) is rooted with Kingroot app, the bootloader is unlocked and I flashed recovery with fastboot to TWRP and got the notify flashing was finished.

When I open the ROM manager app it says my recovery system is TWRP.
My problem: I can't boot in TWRP!?! Intention is to flash system to Lineage OS 17.1.
Not with Volume down+power, not via adb command "reboot recovery" and not with some apps I tried with reboot options, nothing works.
Meanwhile I flashed 3 different TWP images, 3.0.2-0, 3.2.3-0 and 3.3.1, always with the same results like listed above. Booting in TWRP is not possible. Of course I would try it with an similiar image like clockworkmod, but couldn't find one for my device.
I've the same problem in the moment...
Do you've a solution for me?
I tried to install lineage OS 17.1 on a Moto-Z with Android 6.0.1, and failed.
Here is one error I'd like to solve - this command:
fastboot flash recovery twrp-3.3.1-0-griffin.img
Results in:
(bootloader) has-slot:recovery: not found
(bootloader) is-logical:recovery: not found
Sending 'recovery' (20536 KB) OKAY [ 0.443s]
Writing 'recovery' (bootloader) Image not signed or corrupt
OKAY [ 0.481s]
Finished. Total time: 0.932s
twrp-3.3.1-0-griffin.img is the lastest image, from here.
The same error appears when I try to flash the lineage recovery:
fastboot flash recovery lineage-17.1-20201211-recovery-griffin.img
So what is wrong here?
I've been flashing a Moto e5 Plus today, and the ADB messages were the same, except without the "has slot" line. I think they are standard.
I also had trouble getting TWRP to "stick". What ended up working was booting into the bootloader, flashing TWRP and instead of rebooting I selected "recovery" with the volume buttons.
The TWRP site says this in its instructions:
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.

but holding Power + Volume Up after reboot didn't seem to work for me.

How did you flash TWRP - from the bootloader?
Or from the PC via fastboot - in which case there is always the above error, not just with TWRP images.
This is how I flashed TWRP from a linux desktop:
Code:
./adb -d reboot bootloader
sudo ./fastboot flash recovery ~/Downloads/twrp-3.4.0-0-hannah.img
(bootloader) is-logical:recovery: not found
Sending 'recovery' (19798 KB) OKAY [ 0.795s]
Writing 'recovery' (bootloader) Image not signed or corrupt
OKAY [ 0.552s]
Finished. Total time: 1.352s
The first line results in the screen with the open-chested android. Then I ran the fastboot command. Then I selected "recovery mode" on the phone.

Not different from my technique.
So we seem to have different conditions on the phone, firmware, whatever.
