 take me 2 hours to know way the xbox wont boot open close that  xbox count find the fault i just inserted the modchip the wrong way how stupid but that gave me the problems to of "turning off/on-flashing red forever" but i dont think you have a problem with the worng way so better check your connections again or maybe you chip is just flashed wrong did you tried that old one and the new one at your friends that are my 2cents for your problem hope this info helps you a little bit.

if your absolutely sure the chip is flashed properly with x 4979 or later with eeprom embedded then you did something wrong with resoldering the chip to your box

Yep, I´m absolutly sure the chip was solded properly, my friend tested before on his Xbox, and even the embedded eeprom worked as he got a error about impossible to unlock hd, since the embedded eeprom was from my own xbox and the hd key was different.

And believe, I think the solders are ok, even tought, the Xbox still flashing with no chip at all.

Sooooooooooooooo...here I am..with a 3 weeks old Xbox broken for more than a month.

So it was broken a week before you got it?  
I had the same problem, probably what has happened is that in your zeal for soldering, a trace was burned through. I did the same thing. The best thing is to pay someone with the experience and a multimeter to check your motherboard. You should be able to find someone to do it for around 20-25 dollars. If it checks out then have them reinstall the chip. The total cost should be anywhere from $25-50. Or you could forget it, buy a refurbished for $125 or a new for $140. Then sell the broken xbox's hard drive, dvd player, controller, case, etc seperately and recoup some of your money.

The Xbox was working ok for three weeks, the suddenly stopped working with or without chip. Is not what you mention.

Whit the 2.29 cromwell it still frag red/green.

Now, my questions:
1. What the confounder in the eprom is used for?
2. Why Liveinfobeta changed a byte in the 1.5eprom after I saved it?
3. Are we sure 100% that all the eprom from 1.1 to 1.5 are compatible?
4. Starting from the blank 1.1 eprom included in Liveinfobeta2 is it possible to build a true 1.5 eprom?
5. Why the cromwell's bioses works differntly? (I've supposed that the latest built has focus chip support)

I'm now waiting for a brand new 1.4 Motherboard so I can take a look to the eprom and try that one; my next try will be to connect a cheapmod, I've already tested the voltages on the LPC and they are fine, I'm just a little bit scare of the mcpx wire but i've already done that on other boxes.

IF SOMEBODY HAVE ANY OTHER SUGGESTION PLEASE FEEL FREE TO SHARE YOUR KNOWLEDGE this frag thing is really bad for all the xboxers and as I read in the forum we are really a lot with the same prob.
Bye.

P.S. Sorry if my English is not perfect.

Vood did you forget to redo the added modifications needed for ground and 3.3 volts on the lpc of a 1.5 xbox? ( not entirely sure if your chip requires it but am assuming it does.)

Hi all, I have a 1.5 xbox, i've modded it with a 29 wire homebrew mod with 4981_06 xecuter  bios. ( I'm an electronic so I normally know what I'm doing and this is the 20th xbox that I modify) At the beginning everything went fine, the xbox boot up properly and i've installed the latest release of evolution x, xbmc ed other apps; one oer later I was transferring a Divx to the xbox and after the 10% it hangs, so I rebooted the xbox and It started fragging, with and without the modchip. I read for a week topics and messagges in this forum so I decided to try to read the eprom and check if it's corrupted. I took off the eprom from the motherboard and I connected it to a JDM programmer (I didn't back it up with evox)i red it out with liveinfobeta2 and everithing was looking fine except for the confounder number, I'm saying this because i've the backup of a 1.1 and a 1.0 xbox and the 1.5 looks pretty different: Confounder1.0=00000000C0C71900 Confounder1.1=00000000D0DB1B00 Confounder1.5=AE7A11C834844D69 Anyway I don't know what the confounder is used for, so for now forget it. I've tryed to load and save with another name the original 1.5 eprom file and then I checked if they were the same: no! something is different! At the address 031 the original file has a 19(hex) and the one i've saved has a 1A(hex) and I just don't know why, I can just suppose the original one is corrupted. Ok at this point i've builted a some new eprom files according to the fact that all the eproms from 1.1 to 1.5 have the same encription: 1. eprom 1.5 saved with Liveinfobeta2=1.5sav.bin 2. eprom 1.1 original that come from my working box (i've 3 xboxes now) 3. eprom 1.1 original modified with all the parameters of 1.5(serials,videomode,etc)= 1.1mod.bin 4. eprom 1.1 blank modified with all the parameters of 1.5 I could even try some more combinations but I don't have all that time. So, I reprogrammed the eprom with the JDM programmer with all the kind of files, but still fragging. I also tryed to put the reprogrammed 1.1 in my working xbox and its working fine, i've backed it up with evox and compared with the original one there is only a differnce at the address 0f9(the last addresses that i think are not used); then I solded the eprom of my 1.1 working xbox on the 1.5 but still fragging. I also tryed to build bioses with embedded eprom starting from the 498106 xecuter and M7 bios but with no success and then with the 1.8 cromwell-patched bios.....    Something is changed! I dind't see that the xbox with the xecuter bios was fragging red/orange but with the cromwell was fragging properly red/green. Ok I dowloaded 3 kinds of cromwell bios: latest 2.29 the shallax cromwell bios (i don't remember what version) the shallax cromwell with focus and hdtv support SURPRISE! with the last two the xbox stops fragging! Yeah, solid green light, but no video, no audio and no eject ( Whit the 2.29 cromwell it still frag red/green. Now, my questions: 1. What the confounder in the eprom is used for? 2. Why Liveinfobeta changed a byte in the 1.5eprom after I saved it? 3. Are we sure 100% that all the eprom from 1.1 to 1.5 are compatible? 4.

I just disoldered my EEPROM I´ll try to read it with ICPROG this evening.

Sorry about the mistake...my Xbox is non-working for so long that I forget it was a v1.4 version, not a 1.5, so no need for ground and 3.3 mods.

I finally managed to read my eeprom using a serial cable a pair of resistor and icprog......THE FIRST 97 BYTES ARE TOTALLY SCREWED and of course liveinfo even doesn´t load it. So I just writed the backup I saved on my pc when I first loaded Evox on my Xbox and...in a pair of minutes I´ll solder the eeprom back to the xbox...

[VooD]

I
JUST
REPAIRED
MY
XBOX!!!!!!!!!!!!!!!!!!!!!!!

I can´t believe it, finally I managed to repair it, neither cromwell or X2 embeded bios managed to repair the EEPROM ...but BRUTE FORCE (desolder program, solder) WORKED!!!!!!!!!!!!!!!

Sadly my Aladdin seems not be working...maybe I broke it when I first desoldered. That could explain why my friend´s Aladdin operated in a different way while the Xbox still broken.

[colibri]

how did you repair it.. i got a v1.3 mobo and it's toast.. but i still have a locked harddrive i need to unlock.. all my boards are 1.0 and 1.1 any advice.. i just learned that a epromm from a 1.3/1.4/1.5 and aren't compatable with v1.0's maybe if i get my hands on a v1.3 i can finially unlock this beast..
