Does changing motherboard repairs lg g4 bootloop issue?
Guys i want to know whether lg g4 bootloop issue is a motherboard problem ?
Also does your g4 works fine now after changing the motherboard or has it faced the bootloop issue again?
first off yes it will fix the issue if it is not hardware related to anything else in the phone. to answer the question of if it will happen again. that will depend on what is causing the boot loop, majority of the time boot loops can be fixed with out changing the whole mobo or motherboard. i personally have not had any boot loop issue with my unlocked att lg g4 and it is my daily user phone. can you give us more info?
1. any damage or drops?
2. any attempts at rooting or was it rooted?
3. any software mods?
4. any recent changes in temperature of the phone or any kind of changes, cases or battery swap, etc etc?
You can try the baking method, but even if it works, it will only last for a very short time. I tried and it worked for about 5 minutes. I am going to flood the chip with flux and try again, but Im probably pushing chain. The lead free solder they use requires around 220C for about 5 minutes to soften. Quite a bit hotter than lead/tin which has worked very well for a very long time until idiots like Al Gore came along. The Ball Grid Array is a very bad idea IMHO. it depends on solder being used as the conductor, and solder can crack under thermal stress (Especially the crap they use) It is not like soldering a wire lead, where the wire has tensile strength, and the solder merely coats the wire. Another bad idea by a bad engineer with no grasp of the physical properties of materials. I see this more and more today, don't you?
LG has no idea what they are doing. They should get out of the consumer electronics business. Very poor QC
2 time i replacing lg g4 new motherboard together new display and new battery….the problem still same…screen display still not wakeup again….maybe damage caused by one .. maybe the vibrator..mic..loud speaker..camera circuit..with the circuit .. small speakers of the speakers and also the switch on off…i suspected…just a few minutes to see it work normally .. after a few minutes it's back craze
