I'm Sorry can't explain more detail , I'm Not Expert and I'm Junior
I try to fix that problem with trial and error so I share my experience
Maybe I' m to fast say that is the solution to fix the problem but That is my experience
I have 2 patient SX1 1 is Blinking & the other 1 is Contact retailer
Sx1 Blinking Can't upgrade with Winsup because the computer can't detect that mobile
but after diassembly and assembly lucky me that mobile detected by computer so after Winswup become contact retailer but not blinking anymore
I try to fix that with Init map and SX1 is fix and normal so I try that solution to the other one (contact retailer) and fix again
@ mobilemafia
I don't know if that solution not work for you (I'm So Sorry)
No don't ever use cracked martech. It is true that new martech support sx1, but you can't use martech without martech box, where algo is. Otherwise you'll kill your phone...
