Wondering if anyone with an i5 has been able to successfully downgrade to 6.1. I have my blobs saved since 6.0 and am running tinyumbrella server while the phone is in dfu mode but I still get error 1600. The only way I found around this error message is to use refs now but reds now says my i5 is incompatible. Any help appreciated to get rid of this error 1600, thx all.
