Latest version of Android 11.
OOWOW does not recognize FAT32 formatted, 1 partition USB memory devices. Impossible to format USB. Impossible to back up eMMC memory to USB.
I am having an issue similar to user DonQuichotte, in which OOWOW is not able to mount or format an inserted USB stick – thus it is impossible to back up eMMC memory onto the USB memory.
I prepared a 32 GB USB stick with one full-sized partition formatted with FAT32 file system.
I boot into the OOWOW wizard, quit to the main menu, and select 3 - Dump Image from eMMC.
Result: Notice, Can’t find mounted removable or remote storages.
So I select 8 - Avanced, then 5 - Mount dumps storage SD/USB.
Result: the display screen blinks once, with no errors or messages (nothing happens).
Then I select 8 - Format dumps storage USB.
Result: Warning, system fail.
Select 2 - Device testing, then select 5 - USB check info.
Result: /sys/bus/usb/devices/1-1.2:1.0/uevent:DRIVER=usb-storage (similar message is displayed when
USB stick moved to other socket).
It appears that a part of OOWOW recognizes the inserted USB stick, but another part can’t use the information to mount/format/copy eMMC memory.
Should the USB stick be preformatted as one partition, FAT32, or should it be empty? Is there anything else I can try? Thank you.
