**sedra** · 14th July 2014, 12:32 PM

hi all
i have Zumo 660 soft ware missing , the steps that i made is :
1 - update with cure FW
2- format the memory

now i am trying to update with original FW but could't pre-boot
i remove the battery - insert it - drag and drop the FW to updater - press and hold the upper left corner - connect the cable
computer recognize the device as hard disk , but updater did not recognize it at all
any solution

Did you read what GarminCure3 is needed for?
Did you read that you need to be sure that you can enter pre-boot mode BEFORE using it?

i pre-boot the device first and use the cure ,
and i use the updater to cure and it was pre-booted , but now it is not pre-booted

It's because, when SYSTEM SOFTWARE MISSING is displayed, the bootloader enters pre-boot mode automatically.
So, in conclusion, you simply didn't read the manual for GarminCure3. I'm so tired of people not reading simple instructions.
Also I'm surprised you're brave (I should probably use the word suicidal) enough to flash a firmware patched by some program, which you're not familiar with.
So now sit and wait for someone who knows how to enter the pre-boot mode on your device. It should be possible.

How you enter in pre boot with upper left corner on zumo 660?

as Kunix said (when SYSTEM SOFTWARE MISSING is displayed, the bootloader enters pre-boot mode automatically)

Yes, you're right, you can't know for sure. If the system enters the pre-boot mode automatically, and not because of your manipulations, you can't know. That's why you shouldn't use GarminCure3.

That's the right solution in your case. SYSTEM SOFTWARE MISSING means that fw_all.bin is corrupted. You just have to flash it correctly.

yes i have business in garmin GPS and start to learn 2 months ago from your amazing site , but when i have a problem that i could't solve and do not find any old solution i post it here to help me , is there any problem about that or something not legal
honestly i asked some people to teach me in a paid program but they told me just read and you will be learned , and i am trying to improve my information and skills
and as you know if you did not make a mistake you will never learn
