This CR4 XL install guide covers
Corona v3 - v6 Motherboards. You can have the absolute latest version dashboard installed if you wish :)
Recommended Hardware:
(This is what I use myself in my own personal install)
- CR4 XL
- CR4 CORONA QSB KIT
- XECUTER POSTFIX ADAPTER V2 (There are a TON of fakes out there - save your money they are shite quality)
- DOUBLE SHIELDED PRO CPU RST CABLE - SLIM
- JR PROGRAMMER V2 (You can use a v1, v1.1 or a NAND-X and even a DemoN)
- XECUTER CORONA 4GB NAND R/W KIT (IF YOUR NAND IS 4GB)
The CR4 XL Board comes with wires and tuning caps
10pf, 22pf, 30pf, 47pf, 68pf, 82pf, 100pf (the caps aren't always necessary but included for those who like to do a monster fine tune). I personally like to use the double shielded pro cables that Xecuter makes because it gives a perfect grounded line so you are guaranteed a clean wave. For less than a couple of bucks it's a no brainer - and i'm sure there are some bundle kits you can buy where it's probably thrown in as a freebie anyway.
I'm going to break this down as simple as I can. Remember CR3 PRO / SLIM PROTO and how awesome it was? Remember the install guide and the crazy long list of settings and tuning and a zillion options? CR4 XL is as basic as it gets. We took all of the awesome results of CR3 PRO/SLIM PROTO, fine tuned it to the nth degree and made the install as simple as possible and the setup as simple as possible. There's very little for you to do so I will keep this guide as simple as possible. Simple.
Oh and have you noticed there's no messing around with POST QSB's and wire lengths or wrapping wire around the xclamps or messing around with any of that nonsense any more? ;)

DIP SETTINGS:

This will give you dead center timings for Corona. Feel free to set the 3 dip to OFF and/or to add a CAP to get the maximum performance. You really can't go wrong it's a pretty solid setup.
POSTBIT JUMPERS:
These fine tune the resistor on Postbit. The jumper should be set to 0 Ohms by default. In a very few minor instances a 10Ohm or 100Ohm resistor was required to shape a perfect wave (we're talking 5 out of maybe 100 motherboards - so we added the option for those cases)

This is the QSB kit for Corona installs. Not entirely necessary but recommended to ensure a perfect install with all the necessary connectors for NAND-X, JR-Programmer, USB COMMS Cable, RATER etc

Forgive my soldering it's a little ropey here. As you can see it doesn't get much easier than this. I have added a tuning cap just to show you where it sits but it didn't really need one (the caps legs should be cut nice and short, sitting as close to the board as possible - this pics was just for visuals only). I will explain the dip switches and jumpers further in the guide. You can add an extra wire to K for RATER auto reset support (KIOSK).
Extra Pads: ROL is for Ring of Light LED mod, CR_EN is for DemoN Coolrunnr Enable/Disable Mod etc
Use the Xecuter XCLAMP Removal Tool to remove the CPU heatsink and install the XECUTER POSTFIX ADAPTER V2. This gorgeous cheap little tool is something
EVERY modder should have by now....

Solder the Yellow wire (C - Postbit) to the #5 CM solder pad. There is no real need to use the other solder pads as the wire lengths aren't of any real importance anymore. Just keep things nice and neat :)

Flip the board. This is where the Xecuter XCLAMP Removal Tool comes in very handy. The blue wire (CPU_RST) goes to
C5R11 for optimum results. As always I recommend you use Xecuter's Double Shielded Grounded Pro Cable - it's kickass and some retailers usually throw it in for free with a bundle deal. You can also use the IPEX CPU_RST cable which is also just as awesome and super neat and tidy too.

You can EASILY remove an xclamp in seconds (The other sharp end is to help take apart a 360 slim case btw)
If you want to have permanent external access to the NAND, you can hook up an adapter we made a while back which is actually quite nice called the QSB EXT V3 but I think the price was a bit high so it's languishing in the back of the warehouse somewhere. I'll have a word with the boss and see if he can be nice and throw them out cheap to you guys.

If you require support for you installation, do not ask in this thread - create your own thread and include photographs with a detailed explanation of your problem. Thanks.
