HP dv7-3120eo bios flash help needed

[reaper57]

Hey, its me with another HP craptop. I've got this Hp pavilion dv7-3120eo (motherboard number: DAUT1AMB6E1 Rev E) here that has the two led blink problem, corrupted bios/checksum error. I need help locating the bios chip on the motherboard, and help with programing it. I've never programed a bios chip with an external programer before. I got a .rom file from a thread on another forum, but I'm not sure if that is all I need. My programer looks like this one http://www.ebay.com/itm/CH341A-24-25...item234c42a35f
I'm not sure if it's the exact same thing as it has no make or model on it, but it looks exactly like mine.
If someone can point me in the right direction I would be very grateful!

Before you going to flashing:
1. Make sure you was installed the programmer's driver properly
2. Running an executable application from your programmer
3. Make some screenshoots from your screen
4. Give us your screenshoot. Important!! Do without eeprom chips first. Just for take some screenshoot

Thank you for the advice! However, first I am going to need to find out what software to use and most importantly how to connect the eeprom bios chip to the programer. As I said this is my first time doing this so I don't really know where to start.

If using ezp2010 usually like this
1. Detect . Command to detect bios chips
2. Read. Reading bin file from chips
3. Save. Saving bin file for backup to any purpose like restore or to give for other people
4. Load. Load bin file from good file (from forums or already you've backup from working laptop
5. Auto. Command to erase, writing and verify bios
Its done

you must remove the chips from the motherboard first. before doing so make sure the cmos battery has been removed.

you must assemble mini board that legs are separated, unless you have soic8 208ml adapter for pinning IC

solder the chip to mini board which have 8leg, then put into programmer

Re: HP dv7-3120eo bios flash help needed

So I found a chip on the mobo that has a big MX on it and under it it says
2l16050
3c233900
Taiwan
z094235
I can't find any information about it online. Do you think that this is the bios eeprom?
I've added a picture of it in the attachments

UPDATE: The chip turned out to be a MX 25L1605D flash chip.
I managed to successfully flash it with the rom file in the attachments and the laptop is working now!
Thank you for the assistance meritosari!
