How does iPhone5sA 1582 use 4g network?

Iphone 5a 1582 to crack and use 4g, you must jailbreak first. Detailed tutorial:

Step 1: First, add the super snow source: apt.chinasnow.net to cydia, and download and install the operator profile signature patch of CommCenter patch for iOS7.

Then continue to install the Super Snow LTE Activator (National Bank Beta) in the Super Snow Source. After successful installation, the carrier version is 15.7, and then you can wait patiently for a while. Under the right conditions, 4G will appear now. After the emergence of 4G, enter Cydia to uninstall the Super Ice and Snow LTE Activator (Bank of China beta). After uninstalling the Super Ice and Snow LTE Activator (Bank of China beta), the operator version should be 6544.

Step 2: Go to the directory of System/Library/Carrier Bundles/iPhone, and delete all the subfiles in Cmcc_cn.bundle (actually, there is no need to back up here, because there are only four things in it after you use the Super Snowflake LTE activator, and I will upload the original file later).

Step 3: Go into the directory of System/Library/Carrier Bundles/iPhone and copy the files under Carrierlab.bundle to Cmcc_cn.bundle Many people will make mistakes in this step. The correct way is to export all the files in the Carrierlab.bundle folder to the desktop. Then open the Cmcc_cn.bundle and drag all the files in the Carrierlab.bundle folder on the desktop directly into the CMCC _ cn.bundle..

Step 4: Restore the network settings. After recovery and restart, the operator will use English. At this point, go to Settings-General-About this machine, and update the operator to 16. 1 (If you can't update, please click this machine several times and operate it back and forth, understand? It will be normal after the update. ) After the update, 4G will appear automatically. If it does not appear, please see below.

After the update, I directly input the search signal, and then 4G appeared. I believe many front-line friends are like me. If it doesn't appear, it may be that your base station is not deployed, or there is something wrong with the replacement file. You'd better change your mobile phone after brushing it. Of course, it's up to you. You can also use the flowmeter (how to install the flowmeter, please search for it yourself) to quickly restore 4G. . . . After 4G appears, call to see how the call quality is! The call quality here is much better than that with super snow, and there is basically no noise.
