It is stuck on the lg screen

How do I get the phone working for data recovery?

I had mine die the same way. I got my data off by reflowing it with a high-wattage hairdryer (Conair 1875). My method is NOT for the faint of heart as it requires some electronics experience to get right as it’s a limited chance repair, but if you think you’re up to heating it up and maintaining it so it runs to get your data off long enough (without shutting down the phone, as it will likely be truly dead) it works for recovery purposes. I was a little more sensitive about how much heat I used on mine because I had a 509K phone (known to fail, so caution was needed). At the time, I agreed to keep evidence I was in low/nonexistent. It did work, though. That said, an approach to how I explain these kinds of recovery only fixes at work is I mention the LG, and I will flat out say it: If I had to pay the account holder off (I didn’t finance it) to have unlimited chances, I’d have done it. It’s a raw deal for the other side and a good deal for the other since they paid it off at the expense of MY DATA, but the data meant more.

The only real downside is LG may not repair the phone, but they will just replace your dead G4 with another G4 that will probably die the same way and Depot the dead phone. If they replaced it with a reliable phone, I may have sent mine in, but I wasn’t interested in another copy of the same crappy phone because they did the bare minimum — even then if the person financing wanted it done, I did warn them I would not use the phone, and to shove it in storage for all I care if they really wanted to "hold onto something" that I didn't ask for/caused me grief for closure (they didn’t, so I still have mine albeit a ruined board due to data recovery). That was the second (and last) LG phone I ever bought.

Nowadays with the current financing methods (and the death of the $200 phone for a 2-year contract), I buy my phones outright (even if I take the full $1,000 slap upfront) since it hurts less than 2.5-3 years of installment payments. The other issue I had was LG’s track record isn’t good. I have stood my ground on this since 2017 and haven’t looked back. In addition to that, LG has since left the mobile market since they quite frankly lost a lot of customers to this bootloop issue, and their middle finger to anyone affected.

This is how the device that was used to figure it out stands today — it’s a reminder of how I was left on my own to find out and get it done knowing the issue is hardware, and found a way to get it done. I point to it as a way to dispute others if anyone asks what my push was to figure out board level failures. The cat is a hint as to why. (Yes, I did remove the battery as I don’t need it for this, nor do I want a spicy pillow around, if it ever happened).
