No valid licence key found on this device

Hello. Yesterday I factory reset my phone. Today when installing ratio it says “No valid license key found on this device”. It install from the PC with the same key but the key is invalid while enter in the phone.


You need to do factory reset. You need a new code now.

Please don’t do factory reset. Look into the issue shared. It’s exactly same your are in now. @jayanta

I had some issue in my phone so I reset my phone. I didn’t know that the code won’t work after resetting my phone.

Please Dev @Ismael @adham @olivier solve this issue. I know that there are lots of people in queue to get their invitation code. But the wait is killing me.

hi everyone apologies for the delay we had loads of internal work to do and were working cases fifo.

Here are 5 new codes please everyone just comment the one you used so others can use another:


if the code works to install ratio but phone still shows a missing license please mention your old code so we can reset the liscense. We will set up a fix for all that asap.


Thank you @adham. It install from some code but from some some it says the code is assigned to another phone PC but on phone it show invalid licence. Please reset my code it is 2FENk__Dk

Thank you for the new codes.

  1. Works to install Ratio from BllocDesk
  2. BllocDesk says it’s been installed successfully.
  3. Ratio shows Invalid License message on the phone.

So, it’s not the license.

I used HTTPCanary to see what was happening with my phone, and I got the following:
