xbox 360 rrod repairs ?

i have been working with xbox 360 for many years now, out of all the consoles i have ever fixed i have only ever had around 20 not able to be fix thats only around 0.5% of all i have ever done, my repairs are not just those bolts and washers, i do a full gpu replacement to ensure that the xbox will work 100% why pay a really cheap price and just have the xclamps replaced, why not go all the way to ensure happy gaming, i do also offer a simple fix that is just a reflow of the current gpu for 30 this fix will last around a year maybe more, i also repair the open tray error as well for 30 for more information text me on 07531761861
