I need to return my Mediapad s7-303u to stock and it looks like I'm going to have to try and do it through the "fastboot flash" method since when I try to use the onboard stock recovery it seems to freeze. I found a "T-mobile Original Stock Rom" on the Osimood rom site but I'm not sure what build it is or if it would damage my device. I want to use the files in the firmware from Huawei's site but I don't know what a couple of files are. 1 is bq27510_pro.bqfs the other ones are NON-HLOS and huawei_partition.xml Are these important using the method I want to use? If they are how can I flash them to it? i.e. exact command line for them. And in what order should the files be flashed? Also what windows program can I use to uncompress the flash images to see what's inside them? I would like to compare what's going to be flashed to what's on the device. Oh. And what should I erase with the flash method to make sure everything is clean and wiped before I flash to make sure it was like stock?
