Ok, after some reasearch I found out my xt 925 is bricked now. In devices, it shows: qhsusb_dload.
I had this phone perfectly working well, but now it is dead.
Seems like no one is willing to help, but at least I think the creator of this post should say that after the flash is done, USERS SHOULD NOT FLASH THE AVAILABLE ROM VIA OTA, BECAUSE THEY WILL END UP WITH A DEAD PHONE, like I did.
So, please, after you guys do the procedures shown here, DO NOT FLASH THE AVAILABLE FIRMWARE VIA OTA, OR ELSE YOU WILL END UP WITH MONEY THROWN IN THE TRASH.
I tried the blankflash procedure for the moto x, but it does not work.
Hopefully someone will find out a method to unbrick this phone. In the meantime, DO NOT UPGRADE THE OTA FLASH THAT THE PHONE WILL SAY IT IS AVAILABLE.
Also, the topic says that the flash is good for the razr HD models, but I think the problem is that it is only intended for the razr hd 926.
If someone can help, please post here.
Thanks.
