Fix Bulk

Bulk Mode Fix

Bulk mode can seem like a "brick" but is sometimes fixable. If the phone cannot boot into download mode or recovery or the rom.. it may be in "Bulk Mode"

If your device is being detected in Windows device manager as "QHSUSB-Bulk" and you also see USB drives trying to mount then you have a good chance of fixing your phone. Be sure not to format any of the drives in Windows.

Linux users can use lsusb and ls /dev/sd* to see if a Qualcomm Gobi device with 30+ partitions is mounted.. if so you also have a good chance of fixing your phone.

Once BULK mode is confirmed...
Boot into LINUX.
Open terminal and enter: ls /dev/sd*
You should see 30+ drives mounted. Ex: /dev/sdb1, /dev/sdb2, /dev/sdb3... /dev/sdb30, /dev/sdb31, /dev/sdb32...
(If you do not see 30+ drives mounted something is wrong. If using a VM use VMWare and set up properly.)

In terminal enter:
sudo gdisk -l /dev/sdb
(b represents drive letter with 30+ partitions.. could be "sda.. b .. c .. d")
You will now be able to match block # to partition names. aboot is 5... laf is 23 or 24... etc

Confirm aboot and laf number for your device.
Download proper aboot and laf img/bin for your device.

Use "dd" commands in LINUX to write aboot and laf partition from your computer to your phone.
Examples:
dd if=/home/*insert proper directory here*/Desktop/aboot.img of=/dev/sdb5
dd if=/home/*insert proper directory here*/Desktop/laf.img of=/dev/sdb24

Confirm each partition wrote correctly with no visible errors in the output.
Unplug USB cable from phone.
Hold power button for 15 seconds to reboot and power off phone.
Press volume up and while holding vol up.. insert USB cable into phone.
Phone should now boot into Download Mode/Firmware Upgrade screen.
Repair phone by flashing proper stock tot or kdz for your device.
