If you've broken your phone screen, here are some tips for display replacement. We will bring you a case iPhone X as a reference. All you need is a repair kit and a new screen. The repair kit should be included as below: tweezers, screwdrivers, pry piece, suction cup, heating pad, programmer, spudger, battery adhesive, and waterproof adhesive.
Before the screen assembly replacement, we need to check out the True Tone display function and whether it still works as usual or not to make sure the new screen will be working.
Firstly, please long press the phone to turn it off. Then you can use a pentagon screwdriver to unscrew the screws at the bottom of the phone. Please pay attention to putting the screws aside well. You can place the screen face down on the pad for about 2-3 minutes after the heating pad is up to the temperature of 70—80°c. And fix the suction cup at the bottom of the phone, lift the screen gently, and insert a pry piece underneath. Gradually move around the edge of the display, separating the screen along the gap. The display assembly is still connected to the iPhone by cables, so don’t try to remove it completely. Again, please pay attention to the position of the cable to avoid damage. The angle should not be greater than 90 degrees to prevent breaking the flex cable. The process of removing the cover is done.
Next, use a Tri-wing screwdriver to unscrew the screws on the shielding cover of the cable connector. You can use a spudger slightly to extricate the battery and the connector between the screen and motherboard. Now, continue to follow instructions step by step. Detach the earpiece speaker flex cable, and remove the old display assembly.
In order to retain the True Tone function on the display as everything in the iPhone is paired to another screen, it's suggested to make good use of a programmer. Fasten the old touch connector on the corresponding connector of the programmer, and start reading. After everything is done, take off the old screen assembly, connect the new one to the programmer, and start writing.
Please connect the new screen assembly to the programmer, start writing, then place the old screen assembly on the heating pad. You can use a Tri-wing screwdriver to unscrew the screws of the earpiece cable and take out the earpiece. Tear off the protector of the new screen assembly and reassemble the earpiece cable on the new screen assembly. Lastly, tighten the screws. Please pay attention to the position of the grounding chip. Finally, we come to the connection part. Please connect the display cable, touch cable, earpiece cable, and battery accordingly.
If there is something wrong with the repair process or assembly issue, it's better to do some tests after replacing a new screen.
It is the same step as the beginning. Long press to turn it on to do some screen test first. We need to do several tests: 3D touch testing, True Tone testing, and light adjustment testing. If your phone shows, all is usually working. Then you can tear off the waterproof adhesive and make it adhere to the phone body. Press lightly with tweezers to make it adhesive, tear off the film, reassemble the display cable, and touch the cable. And the earpiece assembly, and connect the battery. Install the shielding cover, and tighten the screws. Take off the waterproof film around the frame. Buckle the phone screen, and tighten the screws at the bottom.
Those are all iPhone X screen replacement steps we share with you. If there is any confusion, please leave us your comment.

Recently, some vendors sold outcell as incell on the market. Today's post is to help you tell outcell and incell.
In the first place, we have to know their structural differences. The biggest difference is the position of the touch panel. Incell's touch panel is embedded in the glass substrate, while outcell is above the polarizer and under the glass lens
The display and touch flex cables of outcell are separate while incell integrates two flex cables. Incell must be used with TDDI IC.
Outcell features a separate touch panel while incell’s touch panel is embedded in the glass substrate

Apple has encrypted the battery of iPhone XS and models above. Once you replace the battery, you will get the “Important Battery Message” and “Service” message. To make matters worse, the cycle count of the new battery will show the cycle count of the original battery. Especially the battery data of iPhone 11 series and iPhone 12 series still can’t be accessed. It has been verified by technicians that the “Important Battery Message” will show up after you put in an aftermarket battery or a genuine Apple battery. You can only avoid the problem by letting Apple Stores or Apple Authorized Service Providers replace your battery.
To solve the problem, REWA LAB has verified the latest solution. Today we will share solutions concerning iPhone XS series, iPhone 11 series and iPhone 12 series.
First of all, we will introduce the structure of the battery. The battery can be roughly divided into two parts – BMS board and battery cell. The battery management system board mainly serves as a protection board but also saves battery data. The battery cell is where the power is stored.
Taking iPhone XS for example, we need to prepare a battery data corrector and a new battery cell that can be an original one or an aftermarket one. Disassemble the phone and remove the battery.
Then we need to solder the BMS board of the original battery to the new battery cell. Remove the protective tape on the BMS board. Please do not break the flex cable.
Disconnect the cathode and anode of the battery with a pair of scissors.
Remove the original battery BMS board. Please align the anode and cathode respectively.
Solder with the Spot Welder.
After soldering, install the BMS board. Apply the protection tape.
Since the BMS board is replaced and the battery is protected, the voltage can’t be measured. We need to activate the battery with a Direct Current Supply.
Connect the battery to the programmer. Click reading. Battery data on the BMS board can be seen.
Recalibrate the cycle times and battery efficiency.
Then we connect the display to the motherboard. Connect the power cable to turn on the phone. “Important Battery Message” is displayed.
Please be noted that you can only turn on the phone by a power cable. The above step takes advantage of bugs in iOS and is a very important step. Then we install the new battery. Go to “Settings” to view the battery health information. The maximum capacity is 100% and there is no “Important Battery Message”.
Different from iPhone XS series, the battery data of iPhone 11 series and iPhone 12 series is encrypted and cannot be accessed. That is to say, even if you replace with the original battery cell, the battery data still can’t be read. Worse still, you can’t correct the battery health and cycle count. Recently, REWA LAB has got the latest battery data corrector on the market. Through verification, the corrector can effectively remove the “Important Battery Message” of iPhone 11 series and iPhone 12 series. Next, we will share the operation process in detail by an iPhone 11 Pro.
Remove the BMS board of the original battery. Solder the BMS board to the new battery cell.
Install the BMS board. Activate the battery with a Direct Current Supply.
Because the data of iPhone 11 series can’t be directly read, we need a specialized PCB board to read the data. Install the PCB board to the battery.
Then connect the battery to the programmer. Click reading. Recalibrate the cycle times and battery efficiency.
Connect the power cable to turn on the phone. “Important Battery Message” is displayed.
Then we install the new battery. Go to “Settings” to view the battery health information. The maximum capacity is 100% and there is no “Important Battery Message”. This method is easy to operate with visible repair traces. REWA technicians are now trying to remove the. “Important battery message” of iPhone 11 series and iPhone 12 series without traces. That’s all for REWA LAB’s solutions to the “Important Battery Message” problem. With the development of repair technology and Apple’s continued attention, we believe that new solutions will come up. REWA LAB will keep on bringing the latest information and technology. Please stay tuned. You can buy all tools and supplies in this article on REWA shop. Please feel free to leave a comment on repair topics that you are interested in.
There are three OEM screen assembly suppliers for iPhone 7, iPhone 7 Plus, iPhone 8, and iPhone 8 Plus while there are only two OEM screen suppliers (LG and JDI) for iPhone XR and iPhone 11. The backlight numbers of the three suppliers are LG - DTP & C3F, Sharp - DHK & C01, Toshiba - C11 & F7C.
LG is the universal version with high compatibility while Sharp and Toshiba feature poor compatibility.
If your original screen is LG and you want to replace it, your best choice would be LG because it has superior compatibility and is not easy to have a touch problem. If your original screen is Sharp and Toshiba, you can choose the corresponding screen type and LG will work too as it is the universal version.
If you want to replace your screen with one of these screens, your original screen must be OEM, Pull, or REFURB with the original backlight.
