Huawei have released a OTA software update for the B315s-22, version 21.313.03.00.983. After you install this update LTEwatch will no longer retrieve signal information from the router.
Do not update if you use LTEwatch and want this information available. Now I need help to see if I can downgrade my router. The first step is to find what the last working software version is (I did not have a chance to note it down). Can B315s-22 users of LTEwatch tell me the software version of there off the shelf (not provided by network operator) B315s-22.
You can find it if you log into the router under the settings/system/device information. Once I know this hopefully I can download it and downgrade the router. Veccu's suggestion does not work, I am not sure where he heard that idea from either, I did a quick search and it seems that is more related to unlocking operator locked routers (which mine is not). Indeed it is a general firmware and it comes with preset Elisa settings, The situation is Huawei have told me my operator (Elisa) pushed it to my router because as a company Huawei do not push updates regionally or worldwideto routers (at least that is what they have told me so far). What I really need is the previous firmware version to hopefully fix my problem which is 21.311.03.00.983.
