I decided to root my ME302C tablet to remove some bloatware using an app that required a rooted device. I had the latest firmware so I couldn't use any of the rooting guides online, but I tried Kingo Root, an automatic rooting PC program (all I had to do was enabled USB Debugging), and it worked, at least for one session (after a reboot, it appears to stop working).
After I removed the bloatware, I reset the tablet to its factory state without using the remove root option in Kingo SuperUser (not SuperSU) (I did not know that the option existed). I'm not sure if it would have made a difference if I had used that option, but after resetting, Android booted properly, but I had no lock screen, broken default browser, unresponsive on-screen home button, no notification area, and I lost some options that appeared when powering off (airplane mode and mute). I occasionally get "unfortunately *app* has stopped" errors, but it doesn't appear to affect anything. The tablet works fine otherwise.
I would really appreciate it if someone could direct me on how to restore the default firmware entirely. If I factory-reset, it just removes the apps and resets the settings without affecting the system (clears cache and user partitions), and this website confirms that: search for Isn't Factory Reset exactly the same as wiping /data and /cache? stackexchange. I can't link to it directly. Sorry.
I found a post about an unrelated problem while typing the title where somebody attempted to root using an unofficial firmware update and totally bricked their FHD 10. They ran these commands:
fastboot erase cache
fastboot erase system
fastboot flash update "updatename".zip
Suppose that instead of using the unofficial, rooted update.zip he used, I used an official one from this page (it contains links to updates for my tablet's firmware): search for me302c asus. I can't link to it directly. Sorry.
Would that work? I am assuming that a firmware update is a copy of the entire firmware.
If I could use an update, could you please let me know how to flash it exactly? I can boot into recovery mode, Droidboot Provision OS. It has an option to update the firmware, I believe, called "SD DOWNLOAD". If I place an update.zip file named ASUS_BUNDLE.zip on an external SD card and use the option, it'll look like it's updating (there are a few screens, I think they say "clearing cache" and something else, but nothing mentioned of the system partition) - however, it just acts as if it is a factory reset, taking me back to that state where things are borken.
SD Download doesn't look like it is doing something for every random ZIP you put on the SD card, because if I use a ZIP file that has, say, a picture of my cat enclosed, it will not do anything. I think that it does do something with the ASUS_BUNDLE.ZIP, but just not anything that solves my problem.
In Droidboot, if I plug a USB cable into the tablet and the other end into my PC, an icon will appear saying "USB connected". If I enable USB debugging in Android and connect the tablet to my PC in the Droidboot Provision OS recovery mode, should I run the commands then?
I realize that this is a mouthful and thank you for taking the time to read my post.
