Hi,
today I wanted to flash a new firmware on the M4 Aqua (E2303). But I cant come to Fastboot/Flashmode. In Windows a message comes, which says that the device get not fully detected. On the device manager I get "device not recognized" and the hardware id is USB\CONFIG_DESCRIPTOR_FAILURE or USB\DEVICE_DESCRIPTOR_FAILURE . But when I boot into the system, the usb connection works correctly. Also when I shutdown the device with connected usb I get sony mass storage usb. I also followed the quide the, but without luck: http://troubleshooter.xyz/wiki/fix-usb-device-not-recognized-device-descriptor-request-failed/. And drivers are for sure installed (also installed at least Xperia Companion)
I did...
... adb reboot recovery -> device not recognized" with black screen, reboot (sound like because usb disconnect, but screen is still black), device hangs and it is a odyssey to get it boot again with long hold power and/or plug the reset hole!
... power off -> hold volume down + plug usb -> "device not recognized" and black screen or sony logo... sometimes I had shortly a blue screen, but than the device reboots and than hangs like on adb reboot bootloader
... power off -> hold volume up + plug usb -> device shuts down
... power off -> holt volume up (and also a try with vol up+down) + power till the 3 times vibration comes. but after that it also not boot into flashboot/fastboot.
... wiped the data/internal partitions from recovery -> same like before
... boot into recovery and selected reboot into bootloader -> device hangs
I can only boot into the installed Stockrom and into the twrp recovery.
Any idea where to get the stock rom in zip format to flash it over recovery? Or is there any app to flash the rom from the booted system with root? Anything else?
