It needs to be sent back, sorry. Please contact your dealer or local distributor.

YES!!! the same problem with my UCX II.

Failure in bootloader error 20002000
I just bought it a couple of months ago and just yesterday this came up and there is no way to remove it.  I had the message first and after turning it off and on it came back to life.  But today when I turned it on it didn't work anymore.  just that error message 20002000. I'm desperate.  I do not know what to do.

The unit will be repaired and returned to you.

Oh ok thanks.
I will contact the store tomorrow. 
it's good to know that it will at least be repaired. 

however I would have preferred a Fireface 802, It is much simpler and more direct to use. 
I don't really use any of the interface.  just as I/O (and AD/DA) for all my external gear. 
It's a shame they don't have stock in stores yet.  It would have been great to have gotten just that one

Thanks.

I am still waiting for my set of new screws for UCX II, they are all factory damaged, and now it's been 3 months since I report this problem to my store, and they told me they report this to RME, but that they are extra slow with shipping them new screws. Imagine screws so tiny, they can't even send them via UPS or just regular postage.... If they did, they would probably already come in this 3 months.

RME is starting to get kind of sloppy. Older devices only had some minor problems with supplies over time, but this new ones I think had more problems on other parts of card.

Hello, I would like to ask, how long would a repair like this normally take?  Today I spoke with the store that sold me this UCX II in Paris.  I will send it tomorrow morning.  My question was to know how long I should postpone my mixing jobs in the studio to give some approximate dates to my clients.  thanks for your help and messages

Mine is in Germany since 1 month, and I expect  atleast another month is needed due to supply short..
Sadly we have to wait and hope.

I asked too yesterday to italian distributor, that sent in Germany my UCX II about 1 month ago and they told me that at least/maybe/hope for april something will happen. They offered me also, due to these circumstances and that my unit was broken since day 0, to replace the unit with something other brand available in the shop where I purchased it, but nothing else can compare an RME, so I will wait patiently...

it is logical that someone has a backup but unfortunately it will not be of the same quality.  apparently according to the other customers, this wait will be months.  I have no choice.  I will have to try to ask for a refund or try to exchange it for another product.  it is unfortunate that RME has logistical problems with its products and interfaces.  I understand you.  but I am not willing to wait more than a month for a repair.  Thanks anyway for your messages

I have been reading this thread with great interest, as, you guessed it, I had the same boot loader error message pop up. I have only had the UCX ii for a few weeks. It seems like I can have my money back from the retailer, OR they can send my unit to RME for repair. So, my question is: Has anyone had their unit repaired and returned yet? Any experiences with a repaired unit?

I 'm waiting from beginning of february (my unit worked just few seconds from unpacking). Some days ago italian distributor told me that the april repair forecast will be moved to at least mid-May

Hi there. I've just had the same issue with my UCX II(serial 24069514). Turn it on before a gig and got:

Failure in bootloader
RAM error detected
0200200

Digital I/O were working fine on Totalmix and DAW (with AES) but no audio coming in or out of the analog I/O.

I've contacted with Exosound here in Buenos Aires, and waiting for a response.

I was thinking maybe a recall is needed for this interface, it is so good but this is a serious issue.

so all board labeled rev 1.1 are at risk ? do I void the warranty if I open my unit ? I really wish to know if my ucx II is reliable or not, because right now I can really tour with it knowing that it can fail any day...

edit : seems like the issue is not with the printed board

I'm sorry ... I took a clear photo again and it seems that the adhered flux is reflected and appears to have broken the wire.

It seems that it is incorrect to say that the electronic board is defective. My apologies.

Hello,

My Fireface UCXII has the same error message. Do you know if the spare parts problem is resolved? The model is not available in stores like Thomann or Music Store

Damn. I just got this message that I was afraid of before I bought this audiointerface.
Failure in bootloader.
    ''RAM error detected

The device has been running for almost a year and now i got this message on blue screen. The only thing is, I unplugged it, plugged it back in and it started up normally. But as I understand appearence of  this message is not good sign and I should expect this message to appear again  later or even after the warranty period has expired? Or can I count on the manufacturer's warranty in this case and the official distributor will be obliged to send the card to you for replacement?

Thank you for fast response, MC

I think I'm lucky for the reason that after this error my device rebooted and now it works. But I would like to know, and maybe you seen such case before. Could it be that this error  have appeared for another reason and is not related to soldering issue?  Just like a single time glitch in the firmware, or is it still likely to indicate a possible future dead device?
Asking because everyone who wrote about this error could no longer absolutely do anything with their device, it was just dead, but mine rebooted successfully.
Anyway i`ll ask about serial number in support. Just need to take back a box with sticker from village.
