Acer 5745g (ZR7 Insyde bios) recovery
#1
Hi guys

I was successful in unlocking all advanced featues including uefi boot. It was all working good unti i changed a setting in bios and now laptop wont boot anymore. It tries to boot and all lights come up for a second and it shuts down again in boot loop. I tried recovery for insyde bios but it doesn't boot and shuts again few secs. I tried removing cmos battery but no luck. If i remember i changed some frequency from 1066 to 1333 mhz.

Any ideas how to bring back life.

Thanks

Hi Compuwengo,

Was this a BIOS you modified or one in our forums? I would recommend removing CMOS battery and laptop battery, holding down power button to discharge the board, and then try to boot without the batteries in and just the AC and see if that lets you access the BIOS.

Regards,

Information 
I was updating my bios version and it failed, now my lappy doesnt respond. I found out many ways to recover BIOS via usbdrive, but that process needs '.fd' and other files but acer hasnt provided any of them, there's just an unextractable .exe file on their site http://www.acer.co.in/ac/en/IN/content/drivers
So guys, what should i do to recover my bios.//??
(also,I have created bios backup from same working laptop using universal bios backup, its in .rom format. can i somehow use it..??? i m attaching that file)


Attached Files
.rom   INSYDE-V1.11.rom (Size: 2 MB / Downloads: 24)

well m8 u dont need a .rom u can just use the .fd after u extract the ziped file on acer website the go to the windows bios folder and extract the the.fd from the exe file there it should be something like ZR7x64EC.fd u must rename the EC to EX.fd the flash it even using thumb drive by fn+Esc method i wish this was my problem but my problem went so far since the guy who used rom burnner kit flashed the wrong bios chip whish i hope u wont do if u used a toolkit try to know which bios shall be flashed and also u can help me after ur dont fixing ur laptop u can easly read the both bios firmware and save them as files then send them to me that will only fix my laptop and i will appreciate that

pls guys who ever can send me the firm ware on both bios chips on a working aspire 5745G email me Ntsnpr@yahoo.com
