Help with Jiayu G5 Advanced phone - Android Q&A, Help & Troubleshooting

Hello
My Jiayu G5 has started a continuous rebooting loop. I am on a Skinny sim card in NZ
I took my G5 out one morning opened it and it was continuously rebooting. I have
looked on the internet and found many clips of how to fix the problem on a Samsung
but none seemed to work on the Jiayu. Of course iI might not have done the correct process
right so it didnt work. If someone could tell me the right procedure for the Jiayu so I could
have confidence that it is going tol work I would be very happy.
Regards
Hugh Williams

So you already tried the factory reset?
It is on stock rom?
Than send it in for warranty or bring it back to where you bought it and claim a new one.

If they can't give you the same phone again, they have to repair it or refund you.
With the money you get you can buy what ever you like.

Searching the web i found many people with this problem. Any help or info would be appreciated.

VERIZON LG V10 VS990W BOOTLOOP heeeeeeeeeeeeeeeeeeeelp me please!!!!

Hello friends, a few weeks ago I was using my cell normally and suddenly resumed. Wanting to use it again I realized I did not pass the LG logo screen. At the time I thought it was just that the software was failing. To take the service technician, after 4 days I said no rom had found on the internet. (I live in Mexico, and the city is small so there are not many specialists). I myself then started looking for the solution until you get to this page. Download Two rom, I think it was the 19b and 22a KDZ If I remember correctly. I went with the technical and I gave this product then tested one of the two operating systems but said I had only worked for a while and then returned to the screen logo. When I return my phone, no longer it worked. I press for a full day the power button and nothing happened.
My question is: Is it a hardware problem? it has a solution? battery problem maybe? I have to change the logic board? please them greatly appreciate your help, thank you very much.
Nobody has answered, sorry. It is definitely a known hardware problem. Unfortunately, you will have to warranty return it or swap it through your carrier.

My friend just brought over two of the same models for me to 'fix'. Both are stuck on the LG start screen.
I managed to boot in recovery mode and selected factory reset. After about half an hour being stuck on the start screen, it began to perform the factory reset. After connecting to the WIFI in my house it got stuck on the Start screen again.
This is all while I'm downloading the kdz file in the background.
Try this guide. That's what I plan to do.

LG G2 Mini (D620) lagging and stuck in LG logo after several flash attempts

Hi, I'm new in this but I'm also desperate for help. For starters, I live in Venezuela so it's a bit troublesome to visit a proper tech service and stuff. Well, as I said in the title, the problem with my phone is that it keeps getting stuck in the LG logo. I've already flash it several times, but this solution only seems to work for a few days. I'll explain the problems in a chronological order
1) I dropped my phone in january and the screen broke, so I bought a new one along with a new touch screen. At that time, the only problem that I had was that, even though I had a SIM card in my phone, it didn't have any mobile network signal. I tried many things but gave up on that and the problem's still with me
2) In an attempt to fix that issue, I factory reseted my phone and since that time I got the feeling that something was off with my device but I dind't pay attention to it cos my phone was working appareantly fine
3)After that my device started to get laggy and I tought it was the battery because sometimes it was at 87% and when you turn it off and turn it on again, the battery was at 67% in an instant. It wasn't that bad so I kept using it like that
4) Sometime around last month my phone reboot itself (it was usual that when my device got reaaally laggy it reboots itself). The problem was that it got stuck in the LG logo so I look for solutions and end up flashing it.
5) It worked for a few weeks but the cycle started again. Laggy and then stuck in LG logo. I bought a new battery (wich works fine) thinking that this would solve the problem so I did a factory reset, flash it and then turn it on but the problem still didn't go away.
I'm desperate for help cos I need my phone to work and since I live in Venezuela, I really need the money and obviosuly, I can't afford to buy a new device. Could someone help me?
A little note here. I tried upgrading the software using "LG Mobile Support Tool 2014" but the app shuts down before downloading the upgrade. I don't know if it's due to my laptop being really old (Acer Aspire 5920). I know I have A LOT of troubles but I'm in need of a friendly help!
