If you see only “QUSB_BULK” without “CID Verified” or the tool fails at verification:
Without CID verification, the host cannot trust the channel’s stability. Attempting a bulk write or read on an unverified CID leads to: qusb bulk cid verified
Thus, "CID Verified" is the green light that enables safe, fast, high-volume data movement. If you see only “QUSB_BULK” without “CID Verified”
One common misconception is that QUSB_Bulk_CID_Verified means the bootloader is unlocked or the phone is free of FRP (Factory Reset Protection). This is false. Thus, "CID Verified" is the green light that
CID Verified only confirms the chipset interface is authenticated. It does not mean:
To actually fix a device in this state, you must flash a full stock firmware (including persist, modem, and boot). This will wipe the device. For FRP bypass, you cannot simply flash; you must use specialized loaders that exploit the CID Verified interface to patch the storaged daemon.
Recovering all partitions from a locked or bricked phone for forensic analysis requires raw read access. Without CID verification, reads will be limited or incomplete.
