My Caterpillar S50c is stuck on the boot screen with the following message.
"Your device didn't start up successfully. Boot failure because of the unsigned OS image. Please contact custom service to recover the device. Press power key to shut down device"
Any help will be greatly appreciated.
I can't find a way to get into recovery but when I press and hold volume down and power button, it says "Booting into recovery" then later takes me to the startup screen with the above message.
I can boot into fastboot. Kindly upload any firmware or recovery that can be flashed through fastboot. Or advice how I can put my device into working order.

Alright I need some help here. I borked my Photon this afternoon and have been trying to fix it since then by trying various things to no avail.
Now when I press the power button to turn it on I get "failed to boot 1".
When I press Vol up + power I get "Failed to boot 1 with PwrReason: RWR_KEY_PRESS Starting Fastboot protocal support".
When pressing Vol down + power I get something on the screen for a split second then nothing.
I am able to use fastboot, but can't find anything to flash without failing after sending it to the device. by rebooting in fastboot RSD will see the device. I try to flash any of the stock sbf, and they too all fail when "switching device to BP pass through mode". I am thinking that fastboot is my only way to save the device. but need the proper files and sequence to install and get rolling again.
Well the Sprint store replaced my Photon. They could not bring it back to life. Lol
Hi guys,
I have a small issue with an android mini pc, a Rikomagic MK05. I try to enter in recovery using a toothpick(pressing the recovery button) but all I can see is the RKM logo and then "Rebooting" message. The issue is repeating no longer how much I keep pressing the recovery button. You have the video attached for more information. Can you give me an advice?

Hi,
No matter what I try to do, when I turn on the phone (LeTV x800) with the power down button held in, the phone loads an image of a penguin and then reboots.
When I hold the power up button in and turn on the device it loads the stock recovery. But won't allow me to flash TWRP recovery which I have renamed to the devices required nomenclature (update.zip). It says it is corrupted.
Please help!
Good day everyone. Recently my Mate SE (BND-L34) was left to charge overnight and wouldn't boot up the next day, it's just stuck on the start up screen. Unfortunately, developer options weren't on so no usb debugging although I can only access fastboot when I hold power + vol down. However, when I hold vol + up, nothing happens so I can't access any recovery menu. The phone is completely stock so no root, no custom recovery or firmware, locked bootloader, etc. I did try both methods mentioned here for locked bootloader: "https://forum.xda-developers.com/mate-20-x/how-to/fw-emui-9-1-0-123-evr-al00-t3935995"
Neither of them worked. With HStool, the program (HStool) closes itself after HiSuite has decompressed the download and is about to start installing recovery. The other method mentioned, when "installing recovery" part of the process starts, the phone exits fastboot and goes to the boot screen... both methods actually end in the same result with HiSuite giving me the error message "Recovery Failed" and the phone being on at the boot screen (exiting fastboot before the procedure has finished).
In case it's of any relevance the current firmware on the phone is BND-L34 8.0.0.362. Any suggestions would be greatly appreciated, thanks.
Hello! i don't know how but my rooted Mi A3 last night decided on its own to update to Android 10. So i woke up with all of mine Magisk magic all gone. I tried to root again but my phone is stuck on the 'Mi' boot screen.
So here's the situation:
if i press volume up + power button, instead of entering recovery mode the "no Command" screen shows up;
if i try to fastboot, my pc doesn't recognize anymore my device;
There is any another way to enter recovery mode? Can i flash a boot image on a sd card? Do i have to throw away my beloved xiaomi?
You have most probably incompatible Magisk module which prevents phone from booting Android 10. Flash stock boot image to get phone working (fastboot should work, double check your drivers etc.).
Or perform factory reset from stock recovery:
"If presented with an image of a broken Android with "No Command" shown on the screen, do the following:
- Press and hold the Power button.
- While holding the Power button press the Volume Up button then release the Volume Up button then the Power button."
