Hacking I am on kernel/dashboard 2.0.13146.0 on a Jasper fat so I can do RGH 1.2. Need help!

[Hammyface]

I am sorry if this is a noobie question but there's so much info out there it can be really hard to piece it all together.

From what I understand (and correct me if I am wrong) but RGH 1.2 is a bit better than RGH 2.0 in that RGH 1.2 has better boot times. Since I am on a pretty old dashboard/kernel (2.0.13146. to be exact) I am apparently able to use RGH 1.2 on my Jasper fat 360.

What exactly do I need to buy? Some guides show just the Coolrunner rev C or rev D but do I need anything else? Something to read the NAND? Or is that not needed because the Coolrunner takes care of that? Is there something better and easier than the Coolrunner? Someone here recommended yesterday to someone else that they get one of Team-Xecuter's chips but the item's page said "Jasper motherboards require a QSB and we no longer stock them".

I am not looking for a step by step guide. Just a little assistance in what I need to buy, and whether or not anything I posted above is wrong.

Thanks so much for any help anyone can give!

14699 is the last dash that can be used on RGH 1.

You can use the original RGH 1 wiring and RGH 1 chips for your dash.
These got pretty much the best boot times (RGH 1.2 can be better, haven't had the opportunity to have a RGH1.2 install)

Get a Coolrunner chip and a JR Programmer.
The JR Programmer is used to dump and flash the NAND.

I didn't even realize there was RGH 1.0. I figured the first was 1.2 for some reason.

Does that mean I should seek out a Coolrunner that can do 1.0? Or will all of them do 1.0 through 2.0?

I was reading something about having to remove an oscillator from the chip depending on which Xbox 360 I have? Is that still the case?

Should I get the revision C Coolrunner? I don't see them sold most anywhere

Thanks so much again in advance

All of them do RGH 1.

Revision D should also work.

Thank you so much!

Would you recommend the X360ACE over the CoolRunner for any particular reason?

Do I need to remove the oscillators on either the X360ACE or CoolRunner?

Or, since I am on a Jasper phat/fat console with a fairly low dashboard should I just wait for your R-JTAG guide?

And if I go with RGH, I want to make sure the chip is "using" RGH 1.2 and NOT RGH 2.0. How do I "tell" the chip to use 1.2 instead of 2.0?

It's cheaper and appearantly works quite well.
Call me a TX fanboy but I prefer their chips ;p

Afaik, you don't need to remove anything.


R-JTAG is possible.
Idk if those chips are still in production tho.

Basically, RGH 1 is the first iteration, the fastest.
RGH 2 is for Slims and updated Phats beyond 14699.
R-JTAG is for Phats and RGH 1.2 is an improvement on RGH 2.0
