iPhone 6 iTunes error 56 failures? 3 Methods to Fix It!

Image
Many iOS device users may have received the error messages like iPhone error 56 or iTunes error 56 when they are attempting to update or restore their iPhone. The customer failed to update iPhone 6 IOS by WIFI network at home. When we received the iPhone; it is in iTunes data cable mode. We need flash it again by iTunes, when the flash progress bar reaches 80%, iTunes reports unknown error 56 (the failure has camera power supply circuit and NFC). In order to fix iPhone more efficiency, it's necessary to measure the iPhone camera  circuit; The result is that the camera circuit is normal. Picture 16-5-1 We can ignore the issue of iPhone baseband CPU , if iTunes reports unknown error -1, and then we need to repair iPhone baseband CPU part. But this iPhone can be used normally before flashing, so we suspect the NFC module is damaged; now we decided to remove the U5301_RF first. Remove U5301_RF by QUICK 861DW  hot air rework station, and the measure the diode data for bot...

DIY slove iPhone 6S Audio and Vibration

Image
We will discussion one issue concerning IPhone 6S today concerning the sound and vibration of the device. and vibration does not work whenever the phone gets hot. This can become annoying ,  Let’s take a look at the particulars of this issue and how to resolve it. The receiver signal CODEC_TO_RCVR_N CODEC_TO_RCVR_P of the normal call mode comes out from the iPhone 6s audio IC , passes the FL3153 FL3154 to the receiver flex cable interface J3100, and then sends signal to the receiver to make a sound. There are two microphones in the normal call mode, one is LOWER MICI, the other one is LOWER MIC4. And there are two microphone signals, one is LOWERMICI_TO_CODEC_A1N1_P LOWERMICI_TO_CODEC_A1N1_N, and the other is LOWERMIC4_TO_CODEC_A1N2_P LOWERMIC4_TO_CODEC_A1N2_N. Open WUXINJI dongle, we know that the two sets of microphone signals pass the charger port flex cable, charger port flex cable interface J4600, and then respectively through inductance FL4610 FL4611 and FL3613 FL4614 t...

iPhone 5S iTunes reports unknown error 40 when updating firmware

Image
In today’s world, people are constantly on their mobile devices. U.S. consumers spend an astounding 5 hours per day on mobile technology. We’re reliant on our phones for everything from business to pleasure. Customer said that iPhone 5S iTunes reports unknown error (40) when updating firmware. As the matter of computer system software, when rooting, different computer may have different circumstances. After receiving iPhone and rooting it, I find that when the progress bar goes about one tenth, as shown in picture 7-16, it reports error40. Judging from my repair experience, when the progress bar goes about one tenth, it reports error40, which may be related to EEPROM. Next, remove motherboard and pry up EEPROM, as shown in picture 7-17. Use EEPROM testing jig to test EEPROM, finding no series number in EEPROM, as shown in picture 7-18. Thus I know that the EEPROM is damaged. I am preparing to replace EEPROM. As the series number is stored inside EEPROM, at the same ti...

iPhone 6 motherboard is burned out and cannot be turned on when in charge

Image
Trouble Phenomenon It has 1.4V current when turned off. Customer said that it cannot be turned on as the motherboard is burned out when in charge. Repair Process Plug the original charger, but it has no response. Tear it down and plug adjustable power supply . The current rises to 1.4A. I can feel that the chip is hot, which suggests that there must be short circuit. Remove the shield cover and put rosin on the charging chip, as shown in picture 6-78. The chip is obviously hot when energized and the rosin melts up. Picture 6-78 Replace the chip and then measure the inductor. There is no short circuit now. Clean the chip and energize it to test. The current is normal. Assemble the screen and plug the charger . The charging icon is shown normally, as shown in picture 6-79. Picture 6-79 Here, I recommend a USB current voltage meter . It is small and useful. It is convenient to check whether iPhone is in fake charge, as shown in picture 6-80. Picture 6-80

Solution iPhone 7 Plus iTunes error 56 after damaged water

Image
In modern society, mobile phone is our spiritual partner, mobile phone and we formed a wonderful spiritual partnership, our life has been inseparable from mobile phones, when your iPhone 7 Plus accidentally fell into the water display error 56, do not worry,Vipprogrammer can help you solve. The iPhone 7 Plus dropped into the water and got serious damage, the colleague has simply repaired it for once, but not working, the iPhone 7 Plus now has leakage, no WIFI, no Bluetooth, no vibration, no ringtone, no camera, no flashlight, and stuck phenomenon. Now, we are going to fix it. After careful repairs, all problems we mentioned on above has been repaired except iPhone stuck problem. Considering that it may be due to a software problem, so we connected the iPhone to a computer with an iPhone lightning cable , and then used the iTunes to flash iPhone directly. When the Flash process bar runs to two-thirds, iTunes reports an unknown error 56. Picture 15-11-1 According to our repa...

Simple ways slove iphone 7 plus water damage does not work

If your iphone is flooded, Apple can't help you, do you need to reduce losses and buy new? Not so fast, many people have successfully solved the problem and are happy to use them after the water. Fault description: The iPhone 7 Plus won't turn on, the reason is that the iPhone 7 Plus accidentally dropped into the water while taking photos, after a day, the customers send it to use for repair. Use phone opening tools disassemble iPhone to check iPhone motherboard; there are no obvious traces of water. And then remove all sockets, no traces of corrosion were found on the socket and the socket interface. Connect iPhone logic board to DC power supply , supply power to it, it shows large current and won't boot. Remove iPhone logic board and check it under the 7-45X Trinocular Stereo Microscope , we found that both the capacitor and the main supply capacitor on the bottom of the iPhone motherboard to backlight are corroded. According to our experience, for iPhone 7 or i...

Repair guide iphone6 plus won't boot-vipprogrammer

According customer description,iPhone 6 Plus the main problem is that he is unable to turn on the device, how to diagnose and repair the common failure? don't worry! we have come up with solutions to fix iphone6 plus boot problem. Disassemble the iPhone 6 motherboard and connect DC power supply , there is no short circuit, then triggers we find that the current directly jump from 400mA to 1A, the main board is short circuited, now taking off the main board to observe, the iPhone 6 Nand was repaired before. Use Fluke 15B+ Digital Multimeter  to measure the power supply around NAND, it shows 1.8V short circuit, we are going to remove the NAND to observe under Trinocular Stereo Microscope. As shown in picture 15-8-1. It's a little dirty on Nand chip parts. First, we reprocess the pad. There were 2 points were dropped, as shown in picture 15-8-2. Measure the two points and see if there is any problem. The point is measured as ground connection (the normal point value sh...

iPhone 6 Charging Failure problems

Image
To get your iphone better fixed, please reading the article. The iPhone 6 is unresponsive when plug in charger, so we check whether the charging interface is clogged, however, we can’t find anything in it. Open the iPhone 6 screen to direct test the battery seat voltage B+ with Fluke 15B+ Digital Multimeter , it displays 0.46V, there is no voltage can directly exclude the battery problem. Test battery seat resistance B+385 (abnormal resistance will cause white apple restart symptom) normal, disassemble the single board test the 5V sent by USB. There is a test point below the battery interface. If there is 5V, it means there is no problem with the tail plug flex cable(if not, then replace a new tail plug flex cable to test again). Continue to test which IC is damaged Measure whether the capacitance C1704, C1408 has 5V voltage, if neither of them has 5V voltage, you can short connect Q1701' s pin 1 and pin 3. If either of the two capacitance has 5V voltage, then jumper wire c...
