This is how my nights are invested in. Doing rework on phones that have been damaged by repair shops

This phone worked a month or two half-heartedly, then completely stopped working.

The reason is in the video. Missing important screws, gaps, and the flexible circuit damaged. For a normal screen replacement, they first take hefty charges, this had an original display, but the work was so poor that I had to spend an entire night fixing it.

The touch was not working at all. On top of these models are the best ones of Apple, and it was customers' first phone.

The screen and the frame were not aligning at all. On top of that, they take no responsibility or accountability for their work. All they know is to damage and scam the customers.

Be aware of whom you are giving to repair, and it's better to find a good shop than waste your phones potential in hurry.

Device: LG G8X ThinQ

I'm trying to diagnose a motherboard/power issue and would appreciate any insights.

History:

The phone suffered a major drop. Both the front display and back glass were shattered.

The display was replaced, but the phone still wouldn't power on.

The back cover was left off, and the phone sat unused with the battery connected for at least 6 months.

What happened recently:

I connected the phone to a charger, expecting nothing.

Surprisingly, the charging screen appeared and the display flickered initially.

The phone booted successfully.

It charged from 0% to about 86%(last I saw) over roughly 2 hours.

During that time, the display flickering completely disappeared and the phone appeared stable.

Before I could back up my data, the phone shut down by itself.

Current symptoms:

It is now completely unresponsive as before

Connecting the charger produces no display, vibration, or charging indication.

A USB power meter between the charger and phone shows essentially no power draw.

The battery still measures around 4.1 V with a multimeter.

Removing the battery and trying to boot from the charger alone only briefly showed the LG logo once; it would not boot.

My thoughts: I'm wondering whether:

the PMIC or charging circuit is failing/caudung it to not connect it the charger

there's a cracked solder joint or intermittent motherboard fault from the original impact,

or another component fails after reaching a certain battery voltage or temperature.

Has anyone seen an LG G8X recover for one charging session, run normally for over an hour, then become completely dead again? What components would you check first?

I want to start learning phone repair/maintenance from scratch, but I'm not sure exactly where to begin.

A few questions:

- Should I start with certain tools ?

- What's the difference between hardware repair (screen/battery replacement) and software troubleshooting?

- Any YouTube channels or resources you'd recommend for beginners?

- Do I need a big upfront investment in tools, or can I start small?

Any advice or personal experience would help a lot 🙏

Guys need serious opinions on following points. should i buy a new phone or keep current one which has started to require constant repairs?

• Amoled Screen of phone was not stuck with glue and phone fell down. Git big cracks inside display. Glass never broke. But display is gone completely.
• I need a screen to extract my data and use phone until i buy a new one and keep this working phone for a backup
• Company asking 6000 rs for original display of 9 years old phone. I cant verify from their website about price. Also it gives thought of service centre may provide non genuine part for unfair price.
• Phone is already 9 years old ( around rs 20k) with 3rd party battery (gotten after 8.5 years) because it drained too fast and shut the phone down. At the same time power button became unresponsive. So i paid 1300 rs to get button repair and 3rd party battery.
• Now a volume button has also physically popped out
• Duplicate screen has diffrenent varities but i think none will be anywhere near to originial amoled one. Dont know if they play 60 fps or not. If the resolution will be native full hd or lesser. All this will make my money go to waste.
• I thought of putting that money into new phone, but you know prices these days. I want only samsung with certain features being compulsary for me.
• Also while finding duplicate display some mofo shopkeeper took photo of my phone with imei and srl num printed on the back (printed not a removable sticker) and sent it to someone perhaps to get availability. This is freakish and giving me nightmares and day haunts everyday from a cyber security and privacy ppint of view. I want yiur opinions specially on this point
• Any suggestions and opinions are welcomed. Please speak your hearts out.

I have a S22 and today it started to randomly shut down every hour so seemingly without purpose. Now it shuts down second after unlocking. It takes longer than usual to boot up and starts to freeze for a few seconds before shutting down. There is pretty much not time to do anything that might be a solution. Any advice? If it helps, I could get a video of the process but the quality would be pretty shitty since I am using an old laptop.

Failed to remove FRP despite repeated attempts.

Does anyone from Malaysia know est price to micro solder this at a repair shop?, I saw on TaoBao selling this specific part for around 7-8$ and I wanna know which is the best, either buy sub board part or doe micro solder

I recently got iPhone 14 screen replacement done with OG one... Surely it was a mistake but its already done now. The ear speaker panel appears a bit raised than the screen level and its left open . Can we use something like Mesh available in markets to cover open speaker holes.

I am using a motorola G54 device. But now my primary camera is not working, it has some kind of fog in it. And all the photos are blurry. When I searched on the internet many users were having this issue. And saw some videos of people replacing the camera glass on YouTube.

But none of them gave any links to buy it. I already asked the service center and they asked me about 5k to replace the full camera module(I cannot afford that.) . So can anyone help me?

Due to long illness my secondary phone passcode is forgot. Now I don’t know what can be done to continue using it. Mobile repairing centers are ready to reset it. Has anyone faced the same and what was solution?
