Iphone 4S error -1 solution – looking for proper solutions of iphone software or hardware issue
I have here Iphone 4S Along with strange problem. The story goes like this:
I have bought Iphone 4S Along with -1 error , phone is like new never water damaged. Last owner say that this phone worked good and he wanted to put latest IOS 6.1.3 and have error -1. I try all things here mentioned on forum like few batteries, cables, dock cables, few computers, rehot BB… and always error -1.It just go fine until goes to updating iphone firmware (BB) and error -1.
For now just forget on this phone for a while.
I also have one motherboard from Iphone 4S Along with updating problem. But on this one I can not even start to flash. In iTunes is preparing iphone and after that error 1603 or 1611. kindly dont tell me that this is problem Along with my computer, host file or something similar ( I repair Iphones almost every day) because I already try that. But there is something strange on display when I start to flash, the picture of screen is in attachment. It just freeze there.
I decide to use this motherboard like donor for repairing other iPhones so it is not important to repir it. It is only important to know what kind of error it have.
Now we are going back to first phone. I started to measure/repairing it but didnt find any problem. As I have donor motherboard i try to change U18_RF (some people say here that this can make error -1 ( I didnt measeure first VREG_MSME)) and not to believe now this phone that have error -1 dont want to even start updating and errors 1603 or 1611. I put his originaly U18_RF back (also try Along with connected pin 2 and 4) but same thing error 1603 or 1611 (first time when I connect it will be 1611 and after 1603). Offcourse same screen like donor motherboard…
I put logs from 1603 and 1611 if someone can tell me where to look for a problem kindly do.
Thanks in advance
