@jkbuha

i also checked the operation and I specified it is a donation, not any kind of article shoping.

now it is pending to verify, I hope that get fixed soon

srry for all the headache of this things and huge thanks you for your donation

@mizyshamirul

uhh? :o

what did you flashed exactly to what hardware?

the bios at the first topic is only compatible with the 15z (L511Z)

mmm, well, I had once that beeping issue.

to fix it I had to take appart the machine and remove the optical drive and battery, then plugged again the battery, powered it on, shut it down a,plugged again the optical drive and it worked fine.


if it still acting like that , then it is bricked and you will need the recovery method mentionated at the first post.

not sure if jkbuha made a bios recovery cdrom for the 15z based on the one I made for the xps15 (l502x)

if there isnt any avalible bios recovery cdrom for the 15z , I can try creating one tonight.

6 beeps = Video BIOS Test Failure = Video card failure

I did flash the Bios of my XPS 15z and went OK, is booting fine just a bit slower than original one.
I am on Windows 8.

ok, took me a while to get the required bios and capsule files, repack and upload the patched image for the 15z, especially without being able to use my main laptop ^^

but here it is


--15z Recovery Method--

preparation

* get a working PC with internet ,a cd burner, burning software to burn ISO file on a cdrom and you will also need an emty cdrom.
* download this file , extract it from the RAR archive, then burn the ISO to a CD.
* put the CDrom at the bricked 15z optical drive and turn the machine off.

procedure.

1- turn off your bricked 15z laptop and put the recovery cdrom inside the optical drive.
2- unplug the power cord, and press end button.
3- plug the power cable, and then you relase the end button fast(like just 0.5 seconds after). (the machine should start automatically without push the power button)
4- the bios start reading the cdrom, it load BIOS.cap file from the cdrom.
5- you have to hit F12 fast when the dell splash screen is at the screen, it will bring the device boot menu, then select cdrom. (if you didnt hit f12 in time, you will have to power off the machine and repeat the whole procedure again)
6- bartpe - windows xp will start being loaded.
7- when you are at the main screen, click NO on the network message box. then click the GO button and click "Command Prompt(CMD)" open a cmd prompt. and type "repair" without the quotes, that will launch my main script (Dont close the CMD window, it still needed to reboot the system.)
8- follow the script instructions, it is a little modified script from my main custom bioses.
9- since the automatic reboot didnt worked for the winflash in that boot cd, my script will do it, just wait after the winflash window is closed and the system will autorestart.
10- black screen for some seconds and the flashing screen will appear , if the flashing procedure ends correctly, your BIOS should be working back ^^ (this recovery method installs A12 stock BIOS)
(this is based on the l502x recovery method, but I think it will also work )

let me know if that helped you to recover your machine
