You may have a problem with it but it is not just a code of honour it is also in the warranty. This is why in the BQflasher thread there is a big warning in red telling you that it may break the drive and you take full responsability for it. It realy does not matter how experienced you are, and it applies to some manufacturers of PCs too I have built over 20 yet if I put a hdd in this commercial PC I have the warranty is void.

Hindsight is a wonderful thing, you should have got intouch with Philips the moment you started to have problems. As you have crossflashed they can turn around and say prove you had the problems first. It's not just them being harsh, but they don't know your experience, they don't know if there were problems first, they just know you have done something outside of warranty and against their general advice. It's done to protect themselves from idiots who try things witout the knowledge or experience.
