I have a Samsung Galaxy Tab 2, GT-P3100. It has quite an outdated firmware and is bulky with loads of unnecessary apps. I wish to flash it with CM13.
Now firstly my device isn't rooted. Secondly I have no prior experience in rooting/flashing. Lastly, I don't have an SD card, but do have a PC (and of course internet access to download all the necessary tools).
Under such circumstances, is there a way for me to flash CM13 without having to purchase or lend an SD card? Also, is it worth the flash? Will CM13 run at all, given about 500 mb or RAM is at most free when the device is idle? If not, what are my alternatives, if any?
Edit: I have the zips for CM13 and Gapps.
