I've never seen anyone actually state that they've replaced the chip and resurrected a bricked box.
The tutorials over the net are a mess and never include the needed files. I've posted in the classifieds - hopefully someone will sort me out.
Hi it can be and has been done by many members here..
Most sent motherboard back to seller to replace flash chip but there are a few that have done it themselves.
I tried but naffed it up because I did not research it enough..it's really fairly easy to do as long as you have the tools etc
There are on here a few tutorials somewhere including video.
I would send it back to seller or find someone who can do it properly for you..
