Hello, i found this thread on xda:
In short some portugese guy erased and bricked his Razr by doing:
fastboot erase boot_signed
fastboot erase cdrom_signed
fastboot erase devtree_signed
fastboot erase ebr_signed
fastboot erase mbr_signed
fastboot erase mempodroid
fastboot erase preinstall
fastboot erase recovery_signed
fastboot erase system_signed
fastboot erase logo.bin
fastboot erase mbm.bin
fastboot erase mbmloader.bin
fastboot erase cdt.bin_signed
fastboot erase radio
He erased and deleted every file on his razr so it created perfect paper weight/ total bricked phone.
He said that it wont even power up.
But there is one thing i am curious...
He told that after connecting to pc through usb, :
it recognizes only the OMAP4430 chip, and is detecting and disconnects after 3 seconds and back.
So there is small sign of live.
Now the person who made Boot menu manager, whirleyes,
and later this:This sounds like OMAP ROM Code.
image from - http://omappedia.org/wiki/Bootloader_Project -- look here - there is boot process described
Upon boot, OMAP ROM code will search for a 1st-stage bootloader.
Probably in these location order.
1. Internal Storage (NAND Loader)
3. SD Card
Since you've delete your NAND loader...CPU trying the next order
(at least give you 3 second to upload a bootloader via serial)
There's a chance we can load a custom boot loader from sd-card
p/s : someday when I don't need this phone.. I'll kill it this way
If I'm lucky, I'll get to boot an unlocked bootloader.
but this guy is no more reachable, also he is using windows 8.Thanks a lot for the schematics & the technical insight. Maybe we can try something in this case..
Dude, let's try something...
1- Grab a Micro-SD with at least 4GB
2- Format it to Fat32
3- Extract & copy all the files from the 672.180.41 SBF update to it.
4- Put it into the phone
5- Remove your SIM card
6- Plug the usb cable & connect to the PC.
7- Wait to see if it loads the MBM & try to flash again, using the same files that I mentioned earlier.
Did you understand? / VocÍ entendeu?
I am curious, is it possible to recover in this way ?
Anybody have such bricked razr to test ?
