(UEFI) Dell XPS 15z L511z modded BIOS - and HOWTO

[CodeRush]

@Kasar, if last version of spipgm don't work on Windows, then I don't know any tool that works with that type of LPT-based programmers in Windows. I could write one, but I don't have a motherboard with LPT port.

@jkbuha, thanks. Christmas time is for family and friends, not for BIOSes and chips, I think.

[kasar]

oh

I tested the latest spipgmW (wich is a windows version of spipgm) this one can write the chip, and in windows

thank you

tried programing and verify the chip

both operations worked



I also preffer this one now over flashrom because I dont have to specify programer name everytime I use it and it also show the operation percentaje so I know how much time remaning, I think it is also a little faster, but not sure ^^

hey kasar - did you ever get round to trying the hybrid me8 1.5mb firmware - would be great to see if we have any progress with ME.

also - any luck with shorting the pins on boot to enable r/w? sorry i'm still trying to decipher as much as possible off a mobile device

[kasar]

@jkbuha

nope, didnt tried anything yet.

tomorrow will move to another city for stay in xmas with family, I will dont have too much time or tools over there, and I also will need to have the laptop operational since I have no other computer for traveling

however I will be back on 2/january/2013

then if you point me to the hybrid firmware and timewalker give me a hand to integrate it on the rom file by hex editing on the chip file, I will be able to flash it and report results ^^

[jkbuha]

Besides a merry xmas to you all, I just wanted to say happy one year's anniversary to the start of this thread! Exactly one year ago to the date (and also after way too much food) I wrote the first post to this thread in the hope of sharing (and gaining) some knowledge on unlocking our Dell UEFI bioses. Am happy to say we have accomplished a lot as a team in the last 12 months! Here's to another year of discovery, success but importantly fun doing it

Thanks y'all!

Yeah, New year's eve is right around the corner.. best wishes for the following year. Fullfil all your new year resolution and don't ditch it all in mid January lol
Even thoughI kind of came towards the end of the party I believe like first 3 quarters of the year were not that exciting as the last one.

p.s. on a side note I'm happy Tapatalk just rolled out a full-fledged HD version optimized for tablets so I won't be cramped with my 3.2" smartphone anymore (if you can even call it so ) a nice Christmas gift to go along with a tablet-optimized version of Flipboard released recently. Maybe I will be more productive on the go in terms of forum activity.

yes agreed TW - the last 3 months have been definitely the most exciting parts of the year

I've got some interesting news for you btw - remember when I said that sleep worked fine on my 15z? Well I've finally managed to patch my AppleHDA to work with the 15z's ALC269, and as soon as I deploy it instead of the VoodooHDA - bam! sleep breaks. I'm still trying to figure out why (including trying out your DSDT patch) but thought you'd be interested to know this latest discovery.
