For warranty purposes you can revert to stock jellybean rom. this is the b173 rom which is the only rom available on huaweis website for the g510-200. this is a older rom and has no notification toggles, but power toggles is a very good alternative and much more customizable. hopefully huawei will add the newer b189 rom soon which has toggles.

Step 1: charge your phone to at least 75% if your phone goes flat while upgrading firmware your phone will be bricked!

Step 2: download factory rom http://www.huaweidevice.com/worldwide/downloadCenter.do?method=toDownloadFile&flay=software&softid=NDcxNDM= this is only for the g510-200 phone! DO NOT INSTALL ON G510-100 OR G510-010

Step 3: extract the rom and copy the dload folder to your sdcard

Step 4: shut down phone remove battery for 5 seconds then start phone while holding down volume + and volume - buttons. wait for upgrading firmware to finish it takes approx 2 min phone will reboot when finished and will be like brand new but remember your bootloader is still unlocked!

Step 4: optional. relock bootloader. connect phone in fastboot mode. you must have huawei drivers installed on your pc. fastboot mode = remove battery for 5 seconds start phone while holding volume - when phone freezes on the boot animation you are in fastboot mode. go to start menu in windows and type cmd then right click on cmd and run as administrator. in the cmd box type fastboot devices and you will see a code of about 7 didgets which means you are connected properly and have the correct drivers installed. you can also type fastboot oem get-bootinfo to see if your bootloader is locked or unlocked. now to lock it type fastboot oem lock. done your phone is completely factory stock.
