This is not a ROM thread, so I'm not going to answer again and again and again the same questions over and over and over again.
You can't read - quit this thread now. You can read but you can't understand more or less simple things - quit as well.
You can read and you understand things, but you are too lazy to read the whole thread before asking the question - watch this first. And quit.
This is what we know so far:
1. It's very nice to see that finally someone separated "internal sd card" from userdata partition. So it's no longer linked to /data/media, as it used to be on Asus Transformer, Transformer Prime, Galaxy Nexus etc. but it's a separate partition now - mmcblk0p14. Basically the biggest benefit from that is that now formatting userdata partition will no longer erase virtual sd card content.
2. It seems that NFC and WLAN deep settings are stored on separate partitions: mmcblk0p1 (wlan) and ? (NFC).
3. There is a 5th PHYSICAL core, but it's invisible to the system. Android only sees the 4 main cores. The 5th companion core is not controlled by Android. Tegra 3 architecture itself handles the load balancing between the main cores and the companion core. (Thanks to Diamondback)
4. There is no radio.img in current RUUs.
Download firmware for HTC One X (PJ4610000)
Firmware from 1.28.401.9 RUU
--- MD5 checksum: 83375DF988C86E92417AA8949012A1C2 *PJ46IMG.zip ---
--- CID's added by users requests are marked with green color ---
Why it's better then full RUU:
1. It doesn't contain stock recovery
2. It doesn't contain stock, non rooted system
3. It doesn't contain secured boot.img
4. It wont wipe your data partition
5. It's much smaller
