The iPhone 8 vibration function is not working, we try to fix it by restarting, updating and restoring, but all not working. Is there a problem with the iPhone motherboard?  We need to disassemble the iPhone 8 to check.  After disassembled the iPhone 8, first replace the new vibrator, it's really a motherboard problem. We need to replace the new vibrator. Find a iPhone junk motherboard , take out an vibrator, and then install it to the iPhone 8.  After replacement, power on iPhone 8 to test it, the iPhone mute button, it has response.   Go to Settings to check,  enter the test interface, the vibration function of the first few tests is normal, and the next thing is that there is no vibration function. What's going on?  Is the IC burned? We need to remove the IC and then test it.  Use QUICK 861DW hot air rework station to remove the iPhone vibrator IC, and then check iPhone schematic diagram via ZXW Dongle . Use digi...

As we know, the light sensor and vibrator is very important for iPhone screen. If you want to replace the iPhone screen, you also need to transfer the original screen data to the new iPhone screen(iPhone 8 to iPhone Xs Max),so you can make sure the new iPhone screen will work fine. Here is a  JC V1 programmer  to fix iPhone light sensor and vibrator problem (for iPhone 7- iPhone Xs Max), it also can repair iPhone baseband eeprom IC or iPhone logic eeprom IC problem. The JC V1 Programmer comes with 24-inch HD display screen, three-color LED indicator light, two small connecting seats (for connecting function panel) , two buttons and one function panel (including light sensor/touch connector, baseband function connector, vibration connector) It support 2 languages (Chinese/English) and three lines of code (read/write/burn/save), the function panel can be changed, the software can automatically update What’s the functions? - Repair iPhone Light sensor/ true ...

Recently, we found a problem on an iPhone 6, the iPhone speaker doesn't work. When we answer the calls or playing the music/video, the iPhone 6 is no sound from the speaker.  How to fix iPhone 6 speaker problem?  Please keep reading.  Because the iPhone earpiece works fine, so we think it's not the problem of the iPhone audio IC . Based on our experience, we suspected it's the problem of the iPhone speaker and iPhone  audio power amplifier circuit.  Firstly, we need to disassemble the iPhone.   After the demolition， use digital multimeter to measure the  resistance values of 1# and 2# on the flexible cable   connector of the charging port, the value tested is normal, which means the speaker buzzer is normal.  Continue to measure the resistance between 1#J1817 and ground, 2# with digital multimeter , the value of current is normal, which indicates the circuit from the charging port connector to the U1601 is also normal. ...

After pressing the iPhone power button, the iPhone 6S doesn't respond to boot, the iPhone screen keeps black.  Before the iPhone 6S got this problem, it works fine, after we charge it, the problem arises.  After plugging the iPhone lightning cable to charge it, the iPhone  charging icon appears abnormally, after few seconds, the iPhone turns black.  How to fix this problem?  Based on our repair experience, we suspected that it's the problem of the iPhone charge part. Open the WUXINJI Dongle to check iPhone 6S schematic diagram, we know that there are    three components are  directly related to the charge part, they were  Q2300, U2300 and U4500. Now we start to repair. Disassemble the iPhone 6S, take out the iPhone motherboard. Measure the iPhone motherboard with DPS DC power supply , the boot current jumps from 200mA, it's abnormal, because the normal current should be around 40mA, it's short-circuited. This  p...

Why my iPhone 6 Plus restarts infinitely? When press the iPhone power button, the white Apple logo appears normally, but then it turns off, the iPhone 6 Plus always restarts when the white Apple logo appears.  We tried several software solutions, but all is not working. Now we will try hardware solution to fix this problem. As we know,  the iPhone CPU,   iPhone Nand flash , iPhone logic eerpom IC, iPhone baseband all will cause the iPhone restart failure. So, we need to check them step-by-step.  Firstly, check the working condition for these chips. Measuring the grounding resistance value and power supply for the iPhone CPU, both measured value are normal. Next measuring the working condition of the iPhone Nand flash, it's also normal. When measured the iPhone eeprom IC, we found the bus (AP_TO_EEPROM_I2C) connected to the iPhone logic eeprom IC and the iPhone CPU  has some problem, the grounding resistance value for one of clock bus is mo...

This iPhone 6S fell into the ground, and then the iPhone won't turn on anymore. For the drop-damaged iPhone, mostly the iPhone boot failure is caused by hardware problem, so now we are going to DIY fix it in hardware aspect.  Use phone opening tools to disassemble the iPhone 6S, remove the iPhone display assembly, and then take out the iPhone motherboard. Connect iPhone motherboard to DC power supply , there is no current. The iPhone motherboard doesn’t have an obvious short-circuit phenomenon. Short connect boot pin, and then turn it on, the current tested is larger than normal, which means that a voltage in the boot circuit is short-circuited. Use digital multimeter   to measure the diode data of main power supply for each circuit on the iPhone motherboard, we found the diode data of PP_CPU voltage is smaller than normal value. Because there are many components are connected to the PP_CPU, so we are going to use rosin method to find out the short ...

You have an single-SIM version iPhone Xs Max , but you want Dual-SIM version, is there any way can change Single-SIM to Dual SIM version on iPhone Xs Max?  Yes, here is a way that will show you how to DIY change it in hardware aspect. Firstly,  let's go to Settings->General->About to check the single-SIM version interface,the foreign single-SIM version of the iPhone Xs Max can only install one physical SIM card, the another SIM card can write numbers in a "burn" way to achieve normal communication, so we will see "physical SIM card" and "Digital SIM card" in the iPhone Xs Max "about" interface. Next let's check iPhone Xs Max single-SIM version motherboard under the Trinocular Integrated Microscope , compared with the dual-SIM version iPhone Xs Max, the R26_SIM, R27_SIM, R29_SIM and R30_SIM are not the core resistors. When we change the single-SIM to dual-SIM, firstly we need to use QUICK 861DW hot air rework station and Tit...
