Could anyone elaborate on this? Does it happen with 250gb corona xbox 360e-s too?
Anyone can confirm this?

Wunderbar. So it seems this sk hynix eMMC chip somehow just cannot endure the constant 5 sec reset pulses? How come? So if I see this chip on a 4gb 360e then I can prepare for it to be a sonofabitch?

Got one mfg date 2013-08-12 sk hynix eMMC nand, cr 3 lite glitches once then stuck. out of maybe 10 tries it boots at first glitch, and sometimes very rarely it does not get stuck and will try glitching for 8-10 times then it boots. But most of the time it stops after one glitch i it boots all fine, if not then power out, retry. I'll try the slim proto soon with this though. EDIT: with slim proto it behaves much better, boot rate is OK'ish. Sometimes needs a reboot is all.

However I have seen some machines mfg date 2013-04-xx with sk hynix eMMC nand (corona v6 4gb is what we are talking about) and they all seem to be working fine. What could be the difference?

Dexxxterek. You're in Poland? Where abouts. I'd like to take a look at one of these consoles.

The "non glitchable" Coronas are in every Tesco. There is no problem with v5

Hello. I have tried "Advanced - Create an image without nandump.bin" and everything works perfectly. Earlier I had the same problem - after 2 cycles corona V6 stop glitch and make constant noise of fan. My friend found how to solve this problem (he has just edit something in glitch image with winhex. but did not tell me what :) ) My another friends made idea "Create an image without nandump.bin" and it works for me. Please try this method and post about your results.

P.s. I had glitch image made my friend with method by winhex. but i can"t see what actually was edited. if you are interested - you can see all my files (original dump, my first glitch image which did not work (fributsverchit.bin) and edited by winhex which works too (fributnormalzapusk.bin) and kv_info) http://yadi.sk/d/2qFHKGaQDNFHW

P.P.S. Corona V6 mfr-date 08-04-13

It seems someone in Ukraine knows how to fix it...
Challenge accepted :cool2:

I'll try to find the solution :) even without Xbox (as always)

If you have some high-quality photos of the whole X360E motherboard (problem and good ones!), please send me.

See you later ^_^

P.S. For everyone: the problem is exist. It isn't related to bad wiring or fake CRs. Something new was added [or removed] in august coronas.

120 ohm resistor on E & F point is the solutions for this issue on CORONA V4 & V5 & V6

For this manufactured V6 the problem is other....

Amazing! I will try this soon. Those russians / ukrainians are again at it - with some good tracing work the solution is found :)
After all there were reports on this forum about someone replacing the skhynix emmc with other chips and the trying to rebuild it as 16mb corona, same results - so it was not the skhynix emmc after all :) byt the sb chip sending a reset pulse to the emmc after recignizing something went "bad" (well rgh went bad lol)
