OMG i FINALLY found a fix!!!!! i kept getting the "read-only file system" error with NO su installed/accessible. I couldnt find any forums or thread with a working solution. 98% of them recommended zergrushroot (and/or remount -rw), with about only half the users having successful roots. (if it's of any importance, i have the T679 model) Anyways, I didn't have SU installed and the file system was write protected. since i couldn't get root privileges, i couldnt remount, chmod or install su, and since i couldnt install or chmod, i couldnt root (vicious circle!) After trying 3120597 different zergrushroot versions and 335 other root methods, i decided to go back to the basics, with a little help from a few google searches. I figured the os itself was locking the filesystem, and must have some kind of hidden service preventing remount, or writing to system directories, especially since ADB wasnt even allowed to perform any root functions, even with the usb debug box checked, no screenlock/timeout, and the Samsung usb tether driver installed. that, or superuser wasnt even installed at all! therefore, i figured the only solution was to install it from outside the operating system, which was exactly what i did. Solution: i got busybox/su installer from HERE, then placed the zip on the root of my sd card in windows. then, i simply booted into clockwork/recovery (turn phone off, then hold volume button up, turn phone on while still holding the volume-up button) and installed the zip folder. (if you use the factory recovery mode instead of clockwork [or initially install clockwork with factory recovery] you will probably have to rename each .zip folder "update.zip") Voila! Fully rooted, and with busybox installed too! Also, normal CWM doesnt work on the Galaxy Exhibit II, i believe. you have to use a customized one, found here: xda-developers - View Single Post - Samsung Galaxy Exhibit 4G *This fix does not risk getting viruses since you do not even need a pc, or only need it to download and transfer .zip's to the sd card on your phone. Also, zergrushroot and many other "root kits" (double entendre??) are marked as trojans by antiviruses, whether truly malware or not. both su- and busybox are known and trusted across the globe. the factory recovery mode is prebuilt into the phone, and the galaxy clockwork alternative is based on clockwork mod used on most rooted phones. the entire process takes less then 10 minutes on an experienced users first try. also, btw im new.
