After reading many similar posts, I discovered that this common problem is the esn chip that needs to be replaced, ordered, and programmed .. very bad news ..

At this point I think it's probably more convenient and faster to buy another XTL .. but if it will happen again? ..

Maybe the XTLs after 6-7 years of life they go all on tilt ..

And after all, how I will be able to recover all the 4 model packs that I bought?

Thanks for your reply

- thinking more, now I remember that just after last reflash when I turned on again the pod there were no more symbols that are seen usually in the first screen about the model packs installed, the same thing was repeated I think for another 4 or 5 times, then the symbols have reappeared several times, and then disappeared altogether ..

- The nearest Line 6 Service Center is about 340 km from me, I emailed them to ask for a quote, but I'm sure the repair would cost almost the same if not more than another used Pod..

I'm thinking whether to buy another pod or not .. I am tempted, but I'm still undecided ..

I am worried that this problem can happen to me again .. and I lose even more money..

I know of people who have had this problem twice with different pods ..

It almost seems that these objects are designed to last for only some years .. and if it were, I would feel very disappointed ..

I would like instruments that will last as much as possible .. maybe all my life .. why not? ..

From different years I use products of line 6 in my work as a musician, because I like them a lot, but this latter one is not a problem so negligible ..

I'm confused .. I would receive a sincere advice

PS: about replacing eventually the model pack licenses, how it is possible to contact you from the register gear page?.. I don't see any link overthere

A service center wrote to me: "This not a defective ESN-Chip - it's a defective USB Controller" ".. yet another service center replied more or less the same thing..

I still do not give up, and doing further research I discovered that the responsible part of the problem is instead exactly the SMC chip (Secure Memory Chip) that has failed, the information on the ESN number, firmware USB version, and Model Packs installed, are all in there .. and when that chip fails, the symptoms are exactly what me and others have thoroughly described: dead USB, Model Packs gone, reading all zeros for ESN and USB ..

Since the service centers do not seem to agree with the replacement of the SMC, I was wondering if it was possible get one, programmed for my Pod, which I would let mount by a technician ..

Thanks Perry..

I understand what you say, but already two Line6 authorized service centers to which I explained in detail the problem, they replied they think the problem is due to the usb controller ..

From my extensive research, and from what you say Line6 regarding this issue, we should instead replace the corrupted SMC ..

At the end it seems to me that the only option left is to give up.. or not?.. at least not lose any more time and money in vain..

I'd say the second hypothesis is definitely the most probable .. wednesday I'm going to see a well kept XTL, at a reasonable price .. but I hope to be able to sell the other to retrieve at least some of the money I spent to buy it about a month ago, but since now it is defective, I do not know if I will have the same luck that had TheRealZap, who sold his XTL for $ 20 in less than a perfect .. In these cases here in Italy we say: - "Ci vuole un gran culo" - which literally translated means: - "it needs a big a_s_s" -, that is to say: "it needs a lot of luck", well, who knows, we'll see..

Thanks Don,

I bought a new XTL, it works well, all the model packs are already installed except the "collector classics" (so I presume it has been registered already).. before to my problem I had all 4 packs..

For my old bean XT (sold) I had bought the Triple Pack, and the Bass Expansion, which I then moved to the XTL (which ultimately broke) ..

If possible, I would like to restore to the new XTL exactly the previous state with all 4 model packs, and use instead my own license keys that I bought long ago ..

How can I do?

Very good news!

Thanks a lot for your support!

I will follow your instructions..
