Max supported modem BIT Versions for READ CODES / READ CERT methods
In this help we are going to explain what are BIT versions and we will show you how can you find it in your device.
Bit versions are modem versions, which can be different for every firmware. Our team works on adding newer BIT versions for all models with our new updates. BIT versions are cannot be downgraded however you can flash a firmware which has the same or higher BIT number as your current one.
To check the BIT version of your phone, you have to go to Settings, then About Phone and Software Version. In the software version you will find the BIT version as well.
Let's take an SM-A102U as an example: A102USQU4ASK7
A breakdown of a firmware:
A102U (Model number) SQU4 (Version and security BIT) ASK7 (Date of release and revision).
For us, the BIT number is important because that will determine determine whether the procedure can be done successfully. Usually the BIT version is the 5th caracter starting from the right. If you cound find the BIT number successfully you can search for the modem version in the table below. If the the BIT version is equal or lower than your BIT version the procedure can be done with ChimeraTool.
