My GT-I9192 device keeps rebooting to "GALAXY" logo, even when trying to go into Recovery Mode I have a Samsung Galaxy S4 Mini that turns on just to the "Samsung GALAXY S4 mini GT-I9192" logo and keeps rebooting to it..
even when I try to go into recovery mode it just reboots to this logo and restart again
I download its firmware from sammobile.com and tried to flash it with ODIN. ODIN said everything went successfully, but the problem won't go away
I also tried to install CMW recovery, it went successfully too in ODIN... but I still can't go to recovery mode

Please, what would be the best solution?
That happened with me too, sorry, but your phone is probably bricked. I fixed my S3 by purchasing an un-bricking device off ebay/Amazon. They look like so:



(If your phone is rooted, make sure you have the right root file (International or For a carrier) I corrupted mine because I had the international root file when my phone was sprint.)

Hope this helps!
