Two Sansa Clip Zips stuck in limbo, and reflashing NAND does not help!

[ihatesansaclips123]

Hello everybody! 
I've recently acquired two Sansa Clip Zips, both 8GB, and suddenly one of them started bootlooping out of nowhere! (The other one was originally bricked, showing the (free up 200mb) message, I just wanted to see if I could recover it).
So I saw some guides on how to get access to the hidden NAND partition with the supposedly corrupted firmware, so I shorted the recovery pins and yes, I indeed got access. I think it's important to say the partition is 30MB large, but per the Sansa Recovery guide on the forum it should either be a full gigabyte if working correctly, or 4MB if broken (but the OF is 15MB large, so I don't really know if it should be that large).
I manually installed the bootloader on the update file for 1.01.18 (important to say that the devices originally had 1.01.21, but it should be down-gradable, right?). After reflashing, the symptoms for both devices stayed the exact same! One kept bootlooping, and one got stuck at that error.
My goal is to get the Rockbox bootloader on, so I can access USB Mode and reformat the main partition and fix whatever mess is going on inside, but for now, me reflashing NAND does nothing! I am using Linux, and the dd command is showing a write speed, and yes, I've zeroed out the NANDs before flashing the new firmware on.

I just really want these clips to work, I've gotten them for quite cheap and I'm pretty sad at the fact that the second one died after five minutes of operating :/.

Please help!

TL;DR Any way to install Rockbox bootloader on these devices, where I have no access to the internal memory (other than the NAND)?

I think writing to the smaller disks doesn't actually change anything on the NAND, you need to get the full 1GB. Otherwise anything you copy is probably erased on reboot.

Thanks for the reply! How does one go about acquiring the full gig? Or if it's less, does that mean my device is just toast?
