Today Huawei two mobile g730-u10 and g610-u10 comes with monkey virus problem and luckely i have these firmware both sptool and sd card update firmware. Let's come to the point first i had tried to flash g610-u10 to sp flash tool as press download tab in tool in insert usb cable in mobile sp tool showed red line but after give 2004 error then i desided to flash after update.app file keep in dload folder to sd card try to recovery mode and select update firmware from sd card but dload folder not showing there. I could not repair mobile.
After hardky two hours later another Huawei g730-u10 mobile came with same problem and i had tried same ways but this mobile also not solve .
