Someone from a South African site used this method and it worked to unbrick their Latitude E6400. Still no luck from me. Tried reseating the RAM and CPU.
I have a latitude E4300 which my cousin updated the bios from A23 to A24 but the laptop shut off in the middle of the update now i can't boot to setup or boot options after a while it tells invalid system information - please run setup program. i followed the steps to flash the BIOS again but it doesn't seems like it works, anybody can point me to some other solutions? ill gladly appreciate it.
open CMD and drop the E4300A23.exe on it.. then add (space) /writehdrfile E4300A23.exe /writehdrfile put that in usb stick. take battery and power cord out. hold END key and plug in power .. now it should recover. if not try different usb ports.. and try a different usb stick.. works for sure with sandisk cruzers .. transcend seems a no go. names LOLA***.HDR or E4300***.hdr maybe E4300.hdr Code: in the hdr file with hexeditor LOLA?à.0BIN... HDR..`C.E4300. *** = bios version A23
thanks again for pointing this info, i tried yesterday but no luck i know it takes time to try until it's finally done, will try this today.
Hi there, thanks for all the info here, I'm trying to recover my E4300 that failed BIOS update from A24 to A26. I think I'm having trouble to enter BIOS recovery mode, when holding END key and plug in power, with battery unplugged, I only see battery LED amber and then off, nothing happens. Please advise, thanks!
that's where i am right now however i haven't have the chance to try what LatinMcG suggested last week, ill do it tomorrow , i know it takes a couple of tries until you get it right...
I'm reporting a success story here hopefully to help those who are stuck with bad BIOS on the E4300. It happened when I tried to update BIOS from A24 to A26, the update process hung... Sandisk 4GB flash, formatted with FAT default (slow format took a while), my 1GB USB won't work with no reason. A single E430026.hdr file (extracted and renamed from Dell E4300A26.exe by CMD e4300a26.exe /writehdrfile), LOLA26.hdr or LOLAA26.hdr won't work in my case. Remove battery pack, plug in USB flash, hold END key while plug in AC adapter, battery LED will show orange, release immediately upon seeing orange color, after a couple of seconds, PC will start reading flash, you will see battery LED flashes orange and blue (never RED), for about a minute or two, then reboot, wow, A26 BIOS. I appreciate all the previous postings, though not entirely proven true, inspired me to try and eventually figure out the right way for my specific model. Let me know if I can be of any help to the forum users, good luck!
another success story here, i followed LatinMcG steps and it worked! however i had to rename the file just like jackpapa, my laptop went into reading the USB and finally boot up without any issues; Im re installnig Windows 7 on my laptop, im really happy i managed to get this to work thanks again guys!, if i could i would invite you guys a beer haha thanks again!

Hello, I got a E6420A08.hdr file for my latitude E6420 from E6420A08.exe using DecompNewDell.py I put the E6420A08.hdr file on a 2GB sandisk usb stick and tried the DEL key method, but it's not working for me. The power led stays white for 3 seconds and that's all; it doesn't turn orange not even after 30 seconds. One or two dimms, all usb ports. Any ideas? Thanks
Looking for a HDR file for Dell E6430 BIOS version A03 or lower... Please help because I tried Code: D:\Hardware\HDR>E6430A03.exe -writehdrfile and Code: D:\Hardware\HDR>E6430A03.exe /writehdrfile on my wondows 7 64-bit machine many time but windows just throws an error and nothing happens...
I tried it on my Windows 7 (64-bit) machine. But every time I rum it from command prompt with admin rights I get windows error message that the application E6430A03.exe has stopped working. I used the JimboBobB's python script (DecompNewDell.py) to extract the HDR file.. Now I can extract rom file using the following command Code: E6430A03.exe /writeromfile becasue I am getting the same error message as before
