Can't mount system as R/W!

[Skinjob]

Got a problem with my Huawei Y530, that I can't get past. It's running stock ICS 4.3. I rooted the phone but obviously, without recovery, since recoveries and custom ROMs don't exist for the Huawei Y530, far as I know. I am using the latest SuperSU Pro (4.6) for superuser, and "Root Checker" confirms I'm rooted. The problem is, things like Link2SD mount scripts won't work, because the system is read only. I installed the latest version of BusyBox, FWIW, and it (eventually) said it installed correctly. I tried running Terminal Emulator commands to mount the system as rw, but got blocked with the error "read only filesystem".

Is there a way to mount the system as r/w, on stock ROM and without a custom recovery/bootloader installed?

Maybe a fastboot command will work?

I tried a fastboot command in the Terminal Emulator app... it wouldn't recognize the command. Does it need to be from a computer via the ADB shell? Interestingly.... I just discovered through a YouTube video that there appears to be a clockworkmod-type recovery on the device, that you can boot into. Its limited in what it allows, compared to cwm but.... aside from wipes, the commands include:

1. Apply update from external storage
2. Apply update from ADB
3. Touchscreen firmware update

What I'm not sure of is, if there's a way to use this in-built recovery to open up the r/w permissions so I can change system files.

Sorry for the confusion. I was referring to a PC shell command.

Well the fastboot commands didn't work in Terminal Emulator. The error returned is that the system is read-only. Installing apps that claim to mount the system as r/w didn't work either. Is the PC version of ADB slated to work where the Terminal Emulator wouldn't? (I ask because it's a lot of trouble for me to set this up, as I have a Mac).

I've always been under the impression that the Terminal Emulator can't do all functions of ADB/fastboot commands. Changing the R/W is something that, as far as I am aware, needs to be done while the phone is in fastboot mode.

Uh-oh.... does putting the phone in fastboot mode not require an unlocked bootloader... (which as far as I know, is not available for this phone)?

No, but the R/W change probably will.
