If you have ever succeeded iPhone If you dropped it on the ground and damaged its display, your wallet will most likely cry. In the case of older iPhones that have a classic LCD display, repairs are slightly cheaper than those with OLED or Liquid Retina displays, but usually only if you reach for a non-original display. If you have ever held a iPhone with a replaced non-original display, you will certainly agree with me that the color rendering is definitely not the same as in the case of the original display. But that is only one inconvenience - another arises with iPhones 8 and later. If you use a non-original display on these devices, you will lose the function True Tone.

You might be thinking that the malfunction True Tone is a kind of penalty for letting your iPhone fall to the ground and breaking the screen. In reality, however, it is possible to do this even on non-original displays. True Tone reactivate. Hugh Jeffreys, who deals with the renovation of broken iPhones, reported this in his video on the YouTube portal. He ordered a device called JC from China Pro1000s, which can simply be specified as "diagnostics for iPhones". The JC box itself ProThe 1000s can't do much, but if you buy modules for it, it can really do wonders, including activating True Tone even on non-original displays. The whole procedure is quite simple for an experienced repairman. You can read the serial number from the original display using a special program, which you can then save somewhere. Then you just connect the non-original display to the JV box Pro1000s together with the connected display management module and start changing the parameters. You will overwrite the current serial number of the display with the serial number that you saved from the original display. Then you check the box on the screen, press the write button and you are done.

In addition to activation True Tone Hugh Jeffreys in the video, which you can watch under this breakdown, also deals with reprogramming the Taptic Engine module, which in some cases may not work after replacement. The entire process of changing parameters can be compared to the VIN number on cars. If you decide to replace a non-working control unit in your car with a unit from another car, it will most likely not work for you unless you rewrite the original VIN number in it. I Apple therefore, it has identification numbers written in its displays and other parts of iPhones, which it can then use to iPhone recognize whether you have connected the original part or a non-original replacement part to it. For the entire activation procedure True Tone you can watch in the video below.
