I am trying to flash custom ROMs on my Rezound (bootloader unlocked) but I don't have an SD card for it (can't root or use any write ups for flashing a ROM).
This is my old phone (I currently used a Razr Maxx hd which is rooted and unlocked) - BUT I wanted to try flashing ROMs on my Rezound first so I don't mess it up on my current phone. Pretty much I want to use my Rezound to learn the process and if I mess it up, I will still have my current phone.
Any way! Can someone please give me a little bit of guidance on this? Do I even need to root in order to flash ROMs (I read that I can use ADB to flash ROMs instead of the SD card, but do I need root ?) If I do need root, how do I do this without an SD card? I'm cheap and don't want to buy one & I can't find the original SD that used to be in the phone.
Also, after I root/if I don't have to root, what are some guidelines on using ADB instead of SD card to flash ROMs?
I'm just terrified of flashing a ROM on my Maxx hd without first trying it on the Rezound since I can mess up without losing my daily-used cell phone!
And YES I am a NOOB!
I appreciate any advice! Thank you!
