+Subject: [PATCH] drivers/hwbfm: Disable huawei Bootfail Monitor
+
+* Ive tried to disable configs in defconfig and also removing the driver entirely, but i keep getting build errors after solving an error.
+* I dont know if there is a simpler/better way to disable this since i lack C++ knowledge and its been a long time since ive did something in C++ ( i learnt some basic C++ at high school, but not advanced).
+* Now the phone doesnt reboot anymore and in dmesg appears:
+
+3,1093,2579384,-;func: bfm_init line: 2616, BFMR is disabled!
+
+* This driver is causing the phone to reboot to erecovery.
+* According to dmesg, the driver doesnt see that the phone booted succesfully, and after 30 mins since boot it reboots to erecovery.
