How much do you know about the iPhone display

The unevenness of quality commonly exists in the mobile phone spare parts market. Many non-original screens are actually sold as original. It seems that the quality standard varies from country to country. Asking specific questions before purchasing from your supplier is half of the battle to get cost-effective products, while not every provider in this industry will give you an honest answer. Therefore, always try to master the rule by yourself. How to tell original LCD from the copy? How to distinguish different grades of quality?
Original iPhone LCD Differs from Copy One in These Ways:
                                                                                                          Original                                     Copy
1. Original LCD Assembly possess tighter and easier PCB connector installation onto the logic board

2&3. Original iPhone screen always has the clearer texture of QR code and flex cable

4. The edges of the backlight unit of original LCD are well sealed

5. All original iPhone LCD assemblies are equipped with Waterproof glass lenses

6. The identification code on backlight unit is usually painted while copies are all the same

7. More accurate screw holes
8. No excessive glue residue between glass and frame
9. Apple logo on QR code and flex cable
10. Precisely soldered backlight unit flex cable
11. Colored ring printed around the front camera hole


Till now it’s far more likely that you will have a very distinct understanding of the original and copy iPhone LCD display screens. Your vendors for iPhone LCD displays are effortless to be found in the Asia area especially in the city of Shenzhen China, but a very limit amount can afford to be frank and honest regarding the different grades of quality of iPhone screens. A majority of mobile phone repair stores and facilities owners mainly make their decision on the basis of price and quality. When encountered with this dilemma, the relative more reliable and practical tactic is to conduct your due diligence before purchasing.

How can I recover the data from my dead iPhone 6S?

A faulty or dead iPhone is a disaster for many people, however losing all the photos and data of your phone without any backup seems to be an even greater disaster. iPhone data recovery thus becomes very important in cell phone repair industry. We are going to show you how to recover the losing data from a dead phone.

Connect the battery connector with DC Power Supply, and press the power button to power on, there is no response from the screen.

However, current reading on the ammeter is normal, which indicates that the phone is turning on yet with black screen.

Our initial judgment is that the display circuit might have been damaged, and we need to check LCD/Digitizer Connector J4200. Run diode mode measurement of pins relevant to display on J4200. The measured value of Pin 33 is lower than normal value, which is abnormal.

Pin 33 is the reset signal pin for display circuit, the reset signal sent out by Pin J3 on CPU reaches Pin 33 via FL4221, C4221 and C4220. Our next move is to detach FL4221, C4221 and C4220 for further measurement.
First, remove sponge around the connector with tweezers.

Then stick High Temperature Protective Tape on connectors around.

Heat with Hot Air Gun at 330℃, air flow 1, detach FL4221, C4221 and C4220 from the board.

Then tear off the High Temperature Protective Tape and run diode mode measurement of the two pins on FL4221. The measured value of Pin 2 is abnormal.

Since Pin 2 is connected directly to CPU, we can confirm now that CPU has been damaged. As we all know, a damaged CPU can not be replaced separately. And therefore the 1.8V AP_TO_LCM_RESET signal cannot be supplied. To avoid data loss, we can recover data by voltage borrowing.

Choose an 1.8V voltage point nearby, For example, C4118 for our course today, which is the 1.8V voltage point of BUTTON_MENU_KEY_L.
First, remove sponge around with tweezers.

Then heat with Hot Air Gun at 270℃ to remove black adhesive.
Run voltage mode measurement of C4118, the measured value is 1.8V, which is perfect for all operation.

Apply some Paste Flux to FL4221 bonding pad, the remove tins on the pad with Soldering Iron at 350℃, prepare a length of tin applied Enameled Copper Wire of 0.1mm in diameter, heat with Soldering Iron at 350℃. With one end of the wire soldered to C4118, solder the other end to Pin 1 of FL4221. Once done, clean with PCB Cleaner.

Now we can assemble the phone and test, Connect the battery connector with DC Power Supply and press power button to power on.The phone turns on normally.

Connect the phone to computer with a digital cable, launch the iPhone Data Recovery software iTools.

Go to Toolbox>Phone Transfer, choose ’Restore backup’, and click on ’Backup’ to start the Backup process. Once finished, save all the recovered data on the computer.

Tips: make sure that the screen stays on during the data recovery process, otherwise the data recovery might fail. Also, this works for data recovery only, the phone is still not prepared enough for normal use. iPhone 6s data recovery from dead board completed successfully.

It is a special case for the iPhone 6S data recovery, if you use others iPhone devices and want to recover the date what you lost, REWA will be your best choice. More info please go to blog.rewatechnology.com
