Hi,I found on www that firmwares: V200R001C284SP100 and V200R001C297SP102 are for Huawei E5172Bs-925 - NOT for E5172s-920 !!!You must be sure that Your router is E5172s-920 model. I prepared firmware for E5172s-920 with software V200R001C1158SP101 - only with this software upgrade will be successful. This firmware is MOD_Universal_MPWUDP_V200R001C00SP061.bin - reed INFO.txt in archive. Below links for RAR Self Extracting file with 10% recovery data:https://ufile.io/dlv7m
Before the upgrade process ( and after it) I suggest to you "restore default/factory settings" on the device.
REMEMBER -> Flashing/upgrade software procedure is very RISKY and could BRICK You device !!!
