Newly Launched - iPhone 8/8Plus/X back glass separating with laser machine

For iPhone X, iPhone 8 Plus and iPhone 8, the biggest difference from its previous generation is that both the front and back cover are glass.  Among other things, this glass back enables the iPhone 8’s wireless charging capabilities. The phone’s glass back is gorgeous, but also makes it vulnerable. Although Apple says the iPhone 8 has “the most durable glass ever used in a smartphone,” However, it’s glass, after all, you know, glass, which is prone not only to shattering, but also scratching and other light damage over time. Better not drop your iPhone X. If it’s damaged, you’re in for a nasty surprise: The most expensive smartphone on the market is also the most costly to repair.
broken iPhone 8/8 plus back glass
However, believe it or not, breaking the fancy glass back on the iPhone X will do more damage to your wallet. Cracking the screen can be an expensive business, you need to pay $279 to fix a broken screen. As for the broken back glass, rather than counting as a screen break, it’ll fall under the “other damage” fee which is $549(according to Apple’s repair pricing page)
apple-repair-price
And the back glass is fragile and extremely difficult to repair. The back glass is connected to the iPhone X’s housing with both glue and tiny welds, meaning there’s unlikely to be a simple way of removing and replacing it anytime soon.

iPhone X Face ID not working after change screen repair tutorial

Note: This iPhone X Face ID not working after change screen repair tutorial offer by REWA. You can go to their website blog.rewatechnology.com to watch the video.

Recently we got many messages about face ID not available after screen replacement from our clients, which surprised our technicians greatly. Since the screen replacing would not affect face ID function at all according to our practical verification. However, REWA LAB has done some further researches and will share you the detailed analysis and solution for face ID failure caused by damage of flex cable after repair here.
How does face ID work?
First, let’s understand how face ID works. The whole functional area is dubbed the “TrueDepth camera system”, which is made up of flood illuminator, infrared camera, front camera, dot projector, proximity sensor, ambient light sensor, speaker and microphone. Every time you glance at your iPhone X, the flood illuminator detects your face with infrared light and forms an image. Then the dot projector will project out over 30,000 invisible infrared dots over your face to create a 3D map. Last, the infrared camera reads this map and sends the data to neural networks to create a mathematical model of your face. Your iPhone X will check that mathematical model against the one that you’ve set up and stored on your device to see if it’s a match, and if it is, it will unlock your phone.
How To Fix iPhone X Face ID Not Working After Repairing
How do we repair?
According to the description, this iPhone X was dropped once. However, the face ID is in normal status. It fails to work until a replacement of screen assembly. With all the knowledge, we begin our repair.
Power on the phone and it shows “unable to activate Face ID on this iPhone”. So we resort to resetting face ID. Go to Settings > Face ID & Passcode > Reset Face ID. We get the message “Face ID is Not Available, try setting up Face ID later”. Our initial judgment is that the unavailable Face ID might be caused by misoperation in the screen replacing process. Therefore, next thing we do is to check flex cables that are related to Face ID.
How To Fix iPhone X Face ID Not Working After Repairing
Disassemble the phone. And check the Infrared camera and dot projector module under Microscope first. Nothing goes wrong. Then move to the Flood illuminator module on the earpiece speaker assembly. Check the connector and flex cables carefully. Still, nothing goes wrong.
How To Fix iPhone X Face ID Not Working After Repairing
Then remove screws. And detach the earpiece speaker and front sensor assembly from the phone. Be careful not to damage flex cables in the process since the Flood illuminator module is bonded to glass lens with double-sided tape. We can see clearly that the flex cable where locates the Flood illuminator module is fractured at the edge.
How To Fix iPhone X Face ID Not Working After Repairing
Since the Flood illuminator module is an essential part for Face ID circuit, damage of the flex cable can result in not working of it, which can absolutely affect normal working of Face ID. Also, as flex cable repair is difficult, we can solder the Flood illuminator module to a new flex cable. To replace with a new flex cable, we need to separate the earpiece speaker and the ambient light sensor module from the earpiece speaker and front sensor assembly first. Heating with Soldering Iron, the ear speaker was separated successfully. Then, secure the flex cable in the place with High-Temperature Protective Tape for further separating the ambient light sensor module flex cable. Soldering Iron and Hot Air Gun are required to remove this flex cable. Once done, remove excess tins on the flex cable with Soldering Iron and clean with PCB Cleaner.
Now the fractured flex cable is separated completely. Next thing we do is to replace with a new flex cable. Remove the Flood illuminator module on the flex cable first. Prepare a new flex cable. Apply some Paste Flux to the bonding pad. Align the Flood illuminator module in place with the new flex cable. Be careful with the direction. Then solder with Hot Air Gun. Remove residual glue on the module afterward.
How To Fix iPhone X Face ID Not Working After Repairing
The repair part is almost over right the moment. Next thing we need to do is to re-solder the ambient light sensor module and earpiece speaker. However, the soldering of the ambient light sensor is a most difficult part for this repair. Whatever, let’s do it. Apply some Paste Flux to the bonding pad of ambient light sensor module. Then apply tins to the bonding pad with Soldering Iron. Clean with PCB Cleaner. Apply some Paste Flux to the bonding pad again. Get the detached ambient light sensor module flex cable in position. Secure the flex cable with one specific position soldered by Soldering Iron with curved nozzle first. Then use Soldering Iron with cutter nozzle to complete the remaining soldering process. Clean with PCB Cleaner afterwards. Now we need to solder the earpiece speaker back to flex cable.
How To Fix iPhone X Face ID Not Working After Repairing
It’s time to get the earpiece speaker and front sensor assembly assembled to the display assembly. Re-assemble the phone and test. Press power button to power on. Go to Settings > Face ID & Passcode > Set up Face ID. Face ID can be set up successfully. Press the power button to lock the screen. Press the power button again. The screen lights up. Glance at the iPhone X. The screen can be unlocked automatically. Fault cleared.

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.
How can I recover data from dead iPhone 6S
However, current reading on the ammeter is normal, which indicates that the phone is turning on yet with black screen.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
Then stick High Temperature Protective Tape on connectors around.
How can I recover data from dead iPhone 6S
Heat with Hot Air Gun at 330℃, air flow 1, detach FL4221, C4221 and C4220 from the board.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
Connect the phone to computer with a digital cable, launch the iPhone Data Recovery software iTools.
How can I recover data from dead iPhone 6S
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.
How can I recover data from dead iPhone 6S
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

What do you do when Galaxy S6 edge Plus turn on with black screen

Did you ever encounter with black screen after turning on your Samsung Galaxy S6 edge+? It’s a common issue on Samsung Series. When you press power button, the phone stuck with black screen. Yet the buttons were lightened up and the LED indicator was pulsing. So we know its just the screen that fails to wake up.

There will several common ways we will try to solve this problem.
1. Hold the power button and connect the charging cable
2. Boot to recovery mode and wipe cache partition
3. Factory Reset your Samsung Galaxy S6 edge+

You may also read: iPhone 7 black screen repair tutorial

However, if the screen still stays black, it may relate to hardware issue. That’s what we are going to share with you. Fix Samsung Galaxy S6 edge+ black screen – logic board solution.
Disassemble the phone first, and check the logic board. All going well. For Samsung devices, Black screen and other graphics issues are common problems, which are mostly resulted from the damage of OLED relevant inductors. Therefore, our initial judgment – the fault may be related to OLED circuit.
Measure the voltage value of OLED supply with Multimeter.
Normal voltage value on C9028 and C9026 means a normal voltage and normal status on OLED supply. Next, measure the diode value on each pin on OLED connector one by one. With no value measured on Pin 25 and Pin 27, we judge there might be an open circuit on relevant circuit related to the two pins. Since PLCD_MIPI_D0_N and PLCD_MIPI_D0_P of CPU are connected with Pin 25 and Pin 27 on OLED connector via Pin 3 and Pin 4 on F9013, our next step is to check whether PLCD_MIPI_D0_N and PLCD_MIPI_D0_P are in normal status. Let’s do it.
1. Removing the shielding cover on F9013.

2. Take out the logic board and attach it to PCB Holder for the detachment of F9013.

3. Measure the diode value on Pin 3 and Pin 4 of F9013, which is normal.

4. Continue to measure the diode value on Pin 25 and Pin 27. Judging by the measured value, circuit from OLED connector to F9013 is in normal status.

5. So the fault may be related to F9013. and we need to replace with a new F9013.
6. Align to the right place and solder with a new F9013.

Assemble the phone and test. Press power button to power on. The phone turns on with normal display and normal touch function. Fault cleared.

Hope you can solve your problem with our repairing guide. Any problems or suggestions please leave us a message. We will try to reply you in time.
