Boot loop - flashing via fastboot works, adb does not.

Okay, so I tried my best to search the forums and read the Q+A first, but the suggestions I've found so far didn't help me solve my problem.
I started with Hasoon200's tool kit and successfully unlocked the boot loader. Then, however, I got stuck at installing CWRM (it just wouldn't boot into recovery after installing). So I gave it a try with the "One X one Click" tool kit. I downloaded the n3okernel v34 and -modules as well as the newest nightly build of Cyanogen Mod (cm-10.1-20130414-NIGHTLY-endeavoru).
Now my HOX is caught in a boot loop. No matter which option I choose (fastboot / hboot, recovery, factory reset), it'll always go to the white HTC screen and stay there. Since Q+A's Q11 mentions it: yes, the last time I could boot into the OS (then still the stock image) I disabled fast boot in power settings.
Currently I can only access my HOX via fastboot, I already got a stock image and extracted the boot + recovery images, which I then flashed with the fastboot utility, as suggested in the Q+A's Q9. I erased the cache and rebooted to no avail. I also tried the firmware executable (RUU_ENDEAVOR_U_ICS_40_O2_DE_1.26.207.2_Radio_1.1204.90.13_release_251288_signed) to no avail.
Q+A's Q15 suggests sideloading via adb, but adb won't recognize my device.
I've also relocked the bootloader, this was suggested in another online ressource after flashing the stock boot+recovery images.
The phones HBOOT Version is 1.36.0000. I've noticed a different radio version than the one mentioned in my downloaded RUU; phone says 5.1204.162.29, downloaded file says 1.1204.90.13. I've not yet found a working download link with the right version number.
Please help.

Unlock it, make a full wipe in the custom recovery, install cm10.1, install gapps, flash the boot.img from the cm10.1 Rom and reboot.
So
Unlock it, flash a custom recovery (if you havent got one). If you still have trouble entering it you do this command in the bootloader
Fastboot erase cache

Unlocking the bootloader works, but I'm not able to enter the recovery mode. It only shows a black screen (see attached picture).
EDIT: ok, wait... after flashing the clockwork recovery, I'm now getting into recovery mode. Will now try the next steps you suggested and give feedback later. Thanks a lot so far!

Press the Power and Volume down buttons which will take you the the hboot screen. From there select fastboot and flash a custom recovery like CWM via fastboot.
Now select hboot again and then select recovery!

Okay, so I successfully flashed CWM. I'm now able to boot into recovery. I also succeeded in flashing a boot.img which i took from cm-10.1-20130414-NIGHTLY-endeavoru.zip
c:\One\One\Data>fastboot flash boot boot.img
sending 'boot' (4960 KB)...
OKAY [ 0.684s]
writing 'boot'...
(bootloader) Format partition LNX done
OKAY [ 0.498s]
finished. total time: 1.186s
Now - when selecting hboot - the phone gets to another screen, the one where it displays the "HTC One" logo; I tried flashing the CM-image using fastboot (adb still doesn't work), but got following error message:
c:\One\One\Data>fastboot flash /sdcard update.zip
sending '/sdcard' (200098 KB)...
OKAY [ 25.507s]
writing '/sdcard'...
FAILED (remote: not allowed)
finished. total time: 25.716s
So close, yet so far...

So you have a working CWM installed right?
After flashing the boot.img... do "fastboot erase cache"
now go to CWM(recovery) and mount your sd card... copy the CM10ROM.zip and the gapps.zip to your HOX...
after that select wipe data and then wipe dalvic and cache...
Now select install zip from SD and install the ROM and then the gapps... reboot!

The problem is that I can't - or could'nt - transfer files any other way than using fastboot. However, I've now flashed Team Win TWRP2, and finally I'm able to access my phone over adb or just mount it and access it via explorer. Phew.

FINALLY!
So, if another noob like me finds this thread in the future...
After installing the TWRP2 recovery with flashboot flash twrp2.img, then booting into recovery and mounting my device, I was able to copy the CM-ROM-zip file onto the HOX. Then I rebooted into fastboot again and flashed the boot.img from aforementioned zip-file using "fastboot flash boot boot.img".
Booted again, selected the recovery system, installed ROM from zip file.
I'm getting too old for this ****. Almost had a heart attack when I thought I had bricked my phone. Thanks everyone for holding my hand, I appreciate it.

Good mate !
CASE CLOSED !

Twrp disappears after loading, recovery Red Triangle NO Command

Getting confused.
Loaded Nougat on my Nexus 5x... unlocked boot loader, loaded TWRP 3.0.2-2 rebooted, saw TWRP,
Moving files to the phone to restore using TB, but have not yet done SUPERSU.. reboot back into recovery, Android Flat on back Red Triangle, No command??
Can reboot into the phone it works, just can't get back to TWRP for reasons I can't figure out.
Feels like I missing a step, but can't figure out what. Looked at a lot of pages, but nothing really stands out.
Update: Used fastboot boot [twrp imagename].img
And it got me directly to TWRP. Able to load SuperSU then.
Update #2: What I didn't make clear in this original post was I did in fact flash the TWRP recovery, it just didn't stick.
Command used originally:
Code:
C:\SDK\platform-tools>fastboot flash recovery twrp-3.0.2-2-bullhead.img
target reported max download size of 536870912 bytes
sending 'recovery' (16433 KB)...
OKAY [ 0.421s]
writing 'recovery'...
OKAY [ 0.154s]
finished. total time: 0.579s
My mistake was to then reboot where it was apparently overwritten hence the confusion.

The reason that happens is if u fastboot boot twrp.img u will only have a temporary twrp until u reboot..if u had typed fastboot flash recovery recovery twrp.img then when u reboot the recovery would be permanent...

Actually, I did use flash the recovery. It came up just fine. However, after a reboot, when I booted back to recovery I got the No Command.
I had to re-flash TWRP, and then reboot back to Recover from TWRP, then reboot, then it worked like it should.

The command you posted was to boot a recovery, not to flash one in the recovery partition.
Anyway, you can't just flash TWRP and boot, because the boot will replace stock recovery, you got to flash supersu/another kernel from the recovery after flashing for it to stick.

You Can try this adb command :
fastboot flash recovery twrp_3.0-2-2.img
fastboot boot twrp_3.0-2-2.img
And normaly it's ok you have twrp installed

Thanks for the other responses...
Just to confirm what I did originally (I just unrooted so that I could use Magisk and PPH Root)
Code:
C:\SDK\platform-tools>fastboot flash recovery twrp-3.0.2-2-bullhead.img
target reported max download size of 536870912 bytes
sending 'recovery' (16433 KB)...
OKAY [ 0.421s]
writing 'recovery'...
OKAY [ 0.154s]
finished. total time: 0.579s
However, If after doing this I rebooted the phone etc... TWRP was no longer there again. I had to do the same, force a boot to twrp, and then install Magisk before rebooting for it to stick.
Just in case someone else runs into this confusion.
I am now on Android 7 Nougat on a Nexus 5X with Magisk using PPH Root and can now use Root, Android Pay and some other apps which won't run with root enabled. Happy Camper for now.

The step your missing is after you fastboot flash the recovery don't reboot the phone just yet. You have to reboot the bootloader by typing fastboot reboot bootloader. After doing that use the volume up button to access recovery. Once you do that then you can start the phone.

If you boot with a stock boot.img the android boot process will replace your recovery partition with stock if the SHA256 for the recovery doesn't match what it expects. The way you can stop this is to modify your boot.img, which would happen if you install SuperSU prior to first android boot after a new flash.

All drivers (ADB, Fastboot, Google etc.) are installed and are up-to-date. Bootloader is unlocked and it seems BL reacts the same way like BL is locked.
System is not booting and recovery won't boot too. Is there any way to get an adb shell in another way?

Were you able to solve that?
FWIW, the state you're describing is not unheard of and requires to use the fwtool (reference, for example, here). But that, in turn, requires you can have TWRP installed... because with the bootloader in this limbo state, it also refuses to load TWRP on the fly using "fastboot boot ..."

Nexus 5X stuck in bootup

Hi,
I have a Nexus 5X that was on the latest 8.1 firmware, and I successfully downgraded to the latest 6.0.1 firmware by unlocking the device and flashing everything separately. Here's what I did
Enable OEM unlock in Developer settings
Reboot to boot loader
fastboot flashing unlock
fastboot flash boot boot.img
fastboot flash bootloader bootloader.img
fastboot reboot-bootloader
fastboot flashing unlock (had to do this cos after rebooting, device is locked again)
fastboot flash radio radio.img
fastboot flash recover recovery.img
fastboot flash system system.img
fastboot flash vendor vendor.img
fastboot reboot
After this, I get the "Your device is corrupt. It can't be trusted and may not work properly" boot up message, but continue anyway, after which the device boots up and I set up the new device as per normal.
Then, I tried to flash TWRP in order to install Magisk. It is during this step that the device is stuck in the bootup process with the 4 colorful circles. Here's what I did
Reboot to boot loader
fastboot flash recover twrp-recovery.img
Reboot to recovery to check TWRP has been installed (it has)
Reboot to system (stuck in bootup!)
How can I get it to boot up again?

I ended up waiting for the battery to drain and the device to shutdown.

Rooting Motorola G6 Play gone wrong

Hi everyone,
I bought a Motorola G6 play model XT1922-3 type 374B and wanted root acces on this device.
So I started by succesfully unlocking my bootloader using the following tutorial.
After this a started tried to root the device using this tutorial.
This tutorial doesn't link to boot images anymore so I was able to find the moto-g6-play-jeter-patched-twrp.img somewhere else.
I did the following things:
- reboot to bootloader [Succesfull]
- fastboot boot moto-g6-play-jeter-patched-twrp.img [Unsuccesfull]
The device did boot the twrp image but I was unable to interact with it in any way. I couldn't swipe or press buttons.
I made a short video to show this.
I wanted to retry the whole thing so I did reboot to bootloader but then I accidently entered the following command:
fastboot flash boot moto-g6-play-jeter-patched-twrp.img picture of command prompt
After this I wasn't able to normally boot my device. When I try to do so the screen goes black and says n/a in the left corner.
Please does anyone know how I could either be able to boot my normal stock rom again or to have a rooted rom?
Kind regards Sven Onderbeke

Hi Sven,
This isn't going to be the most advanced reply, as I'm not very experienced with this stuff either, but it seems you have accidentally flashed your twrp image to 'boot', wherever that is, which is why the phone isn't able to boot to system.
Can you still boot into bootloader and recovery (twrp)?
If so, then I'd suggest using fastboot to flash a sock or custom ROM. I'm not sure exactly which one though, you have basically the same model as me and that seems to use the JETER ROMS a list of which are over here (can't post links yet, so you will just have to search on mirrors . lolnet . com /firmware/moto/jeter/official/ or remove the spaces
I seem to have somehow lost the partitions on mine, but will start a new thread question about that.

Just flash a stock boot.img to boot. Then just flash TWRP to recovery. In TWRP, format data. Type yes. Then reboot recovery. Then Use TWRP to flash magisk. Done.

Hi again Sven,
I just wanted to let you know that I just downloaded the following RETAIL ROM
ALJETER_RETAIL_9.0_PPPS29.55-35-1_cid50_subsidy-DEFAULT_regulatory-DEFAULT_CFC.xml
and used the following fastboot commands, one at a time.
fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img
fastboot flash modem NON-HLOS.bin
fastboot flash fsg fsg.mbn
fastboot flash dsp adspso.bin
fastboot flash boot boot.img
fastboot flash system system.img_sparsechunk.0
fastboot flash system system.img_sparsechunk.1
fastboot flash system system.img_sparsechunk.2
fastboot flash system system.img_sparsechunk.3
fastboot flash system system.img_sparsechunk.4
fastboot flash oem oem.img
fastboot flash vendor vendor.img
fastboot erase carrier
fastboot erase userdata
fastboot erase DDR
fastboot flash logo logo.bin
fastboot reboot
Which rebooted into bootloader so pressed "start" and all booted fine now. It looks like we have the same device, so hopefully that will work for you too.
