Will Qtek Provide Warranty Service on a 9100 with 2.26 ROM?

I recently upgraded my Qtek 9100 to the T-Mobile 2.26 ROM and shortly thereafter, my speakers died. In reviewing multiple posts on this site, it seems that others have had the same problem. After wiggling the headphone jack as much as I feel comfortable and inserting more toothpicks and the like in the jack than I care to remember, I have determined that I need to send the unit to Germany for warranty service.

Before doing so, I wanted to revert / downgrade to one of the "official" Qtek releases (1.1.7.5, 1.6.7.1 or 2.17), but I have been unable to do so. I am able to downgrade to the Bubble 1.05 ROM but the 2.26 SPL remains. This prevents me from installing any other ROM except back to the T-Mobile 2.26. I realize that the warranty service centers frown on custom ROMs (such as Molski's - which is great!), but do they feel the same about provider ROMs such as T-Mobile since they are not a Qtek release? I just didn't want to send my phone away for 3-4 weeks only to have them tell me that they can't honor my warranty because of an unofficial Qtek ROM.

Is there any hope in sight to being able to downgrade the 2.26 ROM (and SPL)? Was anyone successful using BootLoader or the like to do so?

Thanks!

Do the downgrade again. I've had to do it twice on a few 8125's before all the versions went to 1.x

Thanks for the suggestion.

I am able to downgrade to the Bubble 1.05 ROM, but Iam still unable to upgrade to a Qtek official ROM afterwards. Reading through the posts, it seems that others are having the same difficulty.

Anyone else have any other suggestions? Has anyone turned in their Qtek for service without a "Qtek official ROM" on it? If so, did they perform the warranty service or refuse?

FYI, David (MMB) recommended sending the unit to Teleservice in Flensberg, Germany. Anyone have experience with them?

Thanks!
