After the jailbreak, remember to update everything in Cydia to make it stable.

Step 2: Next add source: 𝐫𝐞𝐩𝐨.𝐭𝐢𝐡𝐦𝐬𝐭𝐚𝐫.𝐧𝐞𝐭 and look for a tweak named 𝐤𝐃𝐅𝐔𝐚𝐩𝐩 (Figure 1). If you can install Tweak, it will be outside the screen. Your doctor will point to and turn on all the buttons to the blue (Figure 2), then press the green button with the words “𝐞𝐧𝐭𝐞𝐫 𝐊𝐃𝐅𝐔” below the screen. .At this time, the device screen will turn black and 3uTools will receive the device in DFU recovery mode (Figure 3), I would like to congratulate you on getting into the kDFU mode easily.

Step 3: Switch back to the “𝐅𝐥𝐚𝐬𝐡 & 𝐉𝐁 𝐡𝐨𝐚̣̆𝐜 𝐍 upgrade & 𝐉𝐁” tab and select “𝐏𝐫𝐨 𝐅𝐥𝐚𝐬𝐡” or upgrade professional “click on” 𝐢𝐦𝐩𝐨𝐫𝐭 𝐅𝐫𝐢𝐦𝐰𝐚𝐫𝐞 or import software “(Figure 4), remember to select the correct Fw Custom downloaded earlier dentist. Select “𝐅𝐥𝐚𝐬𝐡 ặcor upgrade” at this time, it will display a bulletin board (Figure 5), the doctors choose “𝐅𝐥𝐚𝐬𝐡 𝐀𝐧𝐲𝐰𝐚𝐲 or just install” and this process 3uTools will automatically downgrade to your device. with ios 8.4.1.

Note: Be sure to plug in any USB hole for sure. Loose la is disconnected while running, the machine is dead, I am not responsible for it.
Step 4: If you have to read this step, I would like to express my condolences to you. Because I was not lucky and easy. The next thing to do is that the doctor downloaded me the “𝐅𝐮𝐭𝐮𝐫𝐞𝐫𝐞𝐬𝐭𝐨𝐫𝐞” software so that through it I could access “𝐤𝐃𝐅𝐔”.

Now your device will return to the black screen (kDFU) Note: for machines that 3uTools does not recognize “𝐊𝐃𝐅𝐔” even though the device is already dark, press the home button once The computer will receive it immediately. When 3uTools reports that it has received the device at DFU, then you can go back to Step 3 and proceed. I wish you success.
