[Q] Jiayu G3 - Android Q&A, Help & Troubleshooting

Hello everyone, just bought a new Jiayu G3 and I cannot get any rom/backup to work. I've rooted using Bin4rys 'Root with recovery', but everytime I try to use ROM Manager or any other software to backup or even test rom flashing, my phone just shuts down and a picture with android with his 'hood' open pops up. Could that be caused by a 'bad root'? And could anyone link some actual working, up-to date Jiayu G3 JB rom with a guide on how to install it? Thanks.
P.S. Used to root phones like LG Optimus One back in the day, but I never had any problems like this one.

Bump? :/

[Q] [HELP] LG Chat Optimus (LGC550) stuck on LG boot screen

Hi there guys.
Recently i bought a LG Optimus Chat C550 and tried to root it using this method which worked great!
After that i installed a few apps including Rom Manager and tried to install ClockWorkMod Recovery though Rom Manager. It ask me which model my phone was but since it didn't had my model there i chose 1 that said "And others", the phone rebooted after awhile and now its stuck on LG screen.
I've been trying everything but with no luck, my PC doesn't recognize the phone nor ADB.
I'm not a expert just usually follow guides/tutorials. I can't find anything about how to fix it here on the forum or on google :/
Does anyone know how i can get it fixed?!
Thanks in advance

[Q] Revive LG optimus L5 II Dual E455

I have an LG optimus L5 II Dual E455. For some reason the operative system failed and the android logo appeared broken when I tried to turn it on. I took it to a shop and they make it worst, now it doesn't go beyond LG logo.
I'm trying to reset the phone to factory setting via download mode, but the LG Mobile Support Tool doesn't help that much, it stuck at 4 or 5% and doesn't go further. I'm trying to flash it but it doesn't work either. I'm using LG Flash Tool 2014. I think the problem might be I'm not using the right .KDZ, I'm not really sure.
Can someone help me? Theres a better way to do it? Needless to say, I don't know a lot about this. Also I've never rooted the phone, not that I know anyway.
HI
Hello starfox3000
Needless to say, we don't have much data on XDA regarding our phone LG E455.
But i have compiled a few things here and there.
Please read the posts by slipsystem, they are quite useful for our phones.
The KDZ for our phone is V10D_00.kdz which is available at:
http://csmgdl.lgmobile.com/dn/downloader.dev?fileKey=FW376985432109876543213/V10D_00.kdz
Its a file of size 516 MB. I found this on the XDA forum only and many thanks to the developer who gave the link(Sorry, I don't remember his name right now). I hope it works.
For complete guide to rooting the phone, please refer alley23 guide:

Hope your problem is solved soon.

If you have a custom recovery installed than you can just flash the stock rom LG has provided for the public.
This happened to me not to long ago. The LG support tool is the software you'll be looking for. Download, install, connect device while holding up and use the tool to do the rest.

LG Transpyre | I need a stock rom |

So I kinda messed up.
I soft-bricked my phone. Out of impatiences I didn't
back up my phone. Now my phone is stuck in a boot-loop.
I need a stock rom for my phone so I can push an update through the SD.
LG Transpyre
LG(E) VS810PP
Android 4.4.2
I don't remember what I did last to put it in one.
My phone still boots up. Gets to the LG boot screen then to my custom one.
It stays on the custom loading screen. When I press the power button it vibrates.
Same as with the volume buttons.
It won't load in to Safe Mode
and ADB can't find my device.
I am on Linux (Debian Jessie) so any support will be nice.
I really need this anyone?"
I really need this anyone?

omg bro Ibe been waiting so long for that. Your my hero. Not the guy who posted and never have posted before but I have 2 transpyres needing update so thank you.
Not a problem. Took me a while to find it, every site I found that claimed to have the link kept coming up as invalid. I discovered that I had to tweak the link address slightly and it directed me to the right place. ?
LG tool says phone is disconnected
Hey guys, I had a problem finding the stock ROM but I eventually did, however when I try to flash the firmware using LG flash tool 2014 it says that the phone is disconnected, were any of you able to fix your soft bricked phones using the stock firmware and would share with me what program or methods you used to flash the stock firmware on to the device. Your assistance would be much appreciated.

I've run into a problem when extracting the .kdz file for the VS810PP, when I extracted it into a .cab file I was unable to open it with WinRAR. Any suggestions as to how I can successfully open the .kdz file?
