Chosen Solution

Hi to everybody, i have a question and like the title, i want to know how to reprogram the U601_RF ic on the iphone 5, because, im about to change mine because it has physical damage, and its blinking to me “error 16”, i have heard than i have to insert the serial number of my device on the ic to be paired with the baseband main chip, others tell me about i have to change U4 (Nand Flash) U501_RF (Baseband main chip) and U601_RF to have a successful repair… and others tell me about its not necessary to do anything… just replace it and restore the iPhone, because its a programmable ic, and the U501_RF programs it in the restore… i heard all this theory’s but i don’t have any proof of this… so… i want to know this 3 things

  • I need to reprogram it?
  • How i can do it?
  • Anybody have do this repair yet? (not for iCloud hardware removal, only for solve error 16 from physical damage in the ic, before i have the error, the phone turns on normally but it doesn’t gave signal, after i decided to restore and it gives me that error) Thanks to everybody for any response, i want to solve my problem and discuss about this theme. PD: im going to do the ic replacement when it arrives, and in that moment i will know the truth, but this post its for know about if i have to order any other thing, and again… discuss this enigmatic theme! Greetings!

The entire baseband subsystem is impossible to reprogram. It is possible to copy or repair the content on U601_RF, however it requires the U601_RF to be intact. The baseband main chip has its own boot chain so it may be possible to boot it and restore its own data into U601_RF. I haven’t seen any successful repairs though. So my suggestion is try with a new U601_RF, if not working, replace U601_RF and U501_RF as a set, then use the factory tool to rewrite U4 to match new IMEI. Probably too difficult and too expensive so just replace the logic board or give up altogether.
