    Hi. I will be reinstalling this notebook for a friend, and unlocked BIOS will come handy.

    I have one question: is there any more recent version of the mod with newer ROMs, microcodes and such?

    Another question: does the unlocked BIOS allow for faster memory than 1333MHz?

    It does, however you need proper CPU that supports such memory

    Is it possible to change BIOS on l702x to have XMP (extreme memory profile)?
    Does modded BIOS have watchdog function?
    Thanks

    Anyone know how to clear (or even view) the efi variables WITHOUT being able to boot into anything? Issue I have is that I accidentally zapped all but one entry, but that entry doesn't work to boot into anything. The bios still works, but I can't boot into any OS and there's no shell of course. I'm using the modded A19 bios, but Crisis recovery doesn't work since that just gets me to an older bios but the same entries.

    Hello, this topic is probably a little inactive.

    I have the XPS L702X with the modded A19 BIOS.
    I found this interesting setting called TOLUD, after a little Googling I find this setting has something to do with the allocation of video memory.
    My XPS has 12 GB's of RAM memory and the 2760QM Processor.

    My question is if this setting will affect something or if it is changeable in my situation.
    The GT 555m is a very ****ty GPU.

    I'm hoping to see some reply!

    Hopefully somebody can help me out on this outdated thread and system which I am currently still using.
    Since the stock A19 BIOS didn't support my RAM running any higher than 1333MHz with my 1600MHz cards I flashed this modded A19 BIOS so at least that problem is solved. Unfortunately since installing it my cooling fan is running unusual, even at idle. Fan even turning on at random and quite high while there is only 1-3% CPU load, which I didn't have before I flashed the modded BIOS. Also the system has been cleaned and re pasted with thermal paste so personally I don't think that is the problem.

    I have been playing around with the processor and thermal settings but I still haven't figured out what setting(s) may cause this problem.
    Could anyone maybe elaborate on the processor and thermal settings? or perhaps another setting that has influence on my cooling fan?

    Settings on the processor management, everything the same except "Long Power Limit Time" being 0 (not my image):

    Couldn't find any images of the actual thermal settings though.

    Hi. Thanks you for the bios!

    I wrote Oct 12, 2015 - I found and replaced the picture in the file 0C7F41A9-0A6F-43F6-A0D9-1E2D01DBD7BE_1788.ROM

    Tell me, please - How to repack the wph file with the new Rom? What to set and click in the phoenix? I have the wph file (L702X_A19_Unlocked_Menus_&_updated_cpu_microcode_&_sharadeos_vbioses_version6_beta.rar) and folder with dump (after start phoenix):
