Xiao Bai answers, what is a demon machine?

What is a demon machine; ? What about the demon chance? Here's what I learned. These machines are all hard-modified with locks, which can't be seen from the appearance. Only a professional maintenance master can take them apart! So some time ago, many buyers and even businesses were fooled. As far as I know, only a few people have used this machine ... Originally, Apple had a deep knowledge in hardware encryption, so the 4th generation and 4S fonts have heavy encryption.

The Death of Programming Machine Reading

A4 tube system small font tube all signals. Then look for a breakthrough, that is, an unencrypted IC; So they may choose a small CPU because of the least risk. After replacement, they can use hardware vulnerabilities to read and write small fonts to rewrite baseband data and IMEI. After completion, just rewrite the serial number and model, and you're done. So some will become CH. ZP: Actually, they all changed the information. In fact, the sequelae have long been revealed! Because this small CPU is not encrypted, it is definitely not Apple's original factory, so Apple's server will not have the identification code of this IC. "Whenever the official firmware is upgraded, the progress bar is two-thirds; Apple server will authenticate your baseband certificate; If the certificates do not match, an error will be reported immediately: 3 194! This is also a way to identify this kind of machine at present (and several methods in my post! If you have this machine in your hand! Then you're sorry. This machine can only upgrade its own firmware for life (please consult me for details). And the baseband of this machine will never be upgraded to D. Because upgrading to baseband will prompt 3 194 to report an error. Only self-made firmware can be brushed. And then solve it. . In addition, some machines will become three noes after hard fall. . What is three no? No baseband, no Bluetooth, no wifi. . In the words of this demon. . It's normal to be lucky. You can continue to use it as long as you don't brush the machine. . If it is not good. You will find that after the next restart, you will return to the original shape. It's three noes again. Don't panic at this time. . Open the back cover. Blow it twice with a hot hair dryer. It can be used again after being turned on (about the principle? Experts should know. I won't go into details one by one). But this is only a stopgap measure. It can't be solved for a long time. I suggest you have this kind of machine. . Keep it for use. It is better to sell (suggest not to destroy the world again. Keep it for yourself. ) That's all. . Welcome to add. .
