G4 Dead Software - G4 Q&A, Help & Troubleshooting

I`ll keep it short: I rooted it, wanted to do flash something without unlocked Bootloader and now it wont start, and also the Download Mode doesnt work anymore...
So I just wanted to know, where is the Software saved on? Do I just have to buy a new Motherboard, some other parts or can I alredy sell the phone with no hope it will ever work again?

Unfortunaly Download Mode doesn`t work... I do have warranty, but I dont think LG will even try to fix it, because it`s my fault. ..

not sure if it will work tell them you used bridge to update firmware and it didnt finish.. i have heard people saying to use lg bridge and disconect .. search or make a new thread about telling them that.. so they may fix it good lock.

[Q] Stuck in Secure booting Error

Hi
I´m a very new in this field, so I would appreciate some HELP!
I tried to find a way to have other ROMs installed on my Optimus G, but got lost in the proces and am not really sure where I ended.
The today I got a software update from LG, I installed it, but now I am stuck in:
Secure booting Error! Cause: boot certification verify
I simply don´t know what to do?
Thanks to whoever will bear with me...
Do you have a LS970 or a e975? Your sig says E975, in which case you need to use kdz updater to go back to complete stock.
Sounds like you are still locked. If you want to stay locked then look at Imperium Agent to see what you can remove/move and what you can't. Otherwise you need to be unlocked to install anything other than Imperium Agent.

As far as I can tell its e975, I come from Denmark and thats what they call it here...
I sent the phone to repair and of course they said that unofficial software had been installed on it, but they also said, that it was software for another model... :-S I guess in my attemot to root and everything I have tried to install the wrong thing!
So I have had them return it and hope to find a solution myself (all though at this point I am not sure if I ever will be able, if it wasn´t for guys like you!)
You think I can use kdz updater even if my phone is completely dead?
I´ll get hold of it and see what happens when I receive the phone...

Is your phone in Qualcomm QHSUSB__BULK mode?
If yes I recently got this problem on my D855 after getting an OTA update, it hardbricked, it will need to be boot repaired, the owner of the board diagnostics software is in the thread you got your software from, he restricted his software so that it will give the said error.
He charges 50 USD for repairing boot, I returned my phone to the seller, you should try the software in offline mode, i-e disconnect from the internet before launching the application, if it works then tell us, if not then probably the best option will be to ask the owner of this software for access.

My G4 H815 belivies it is a h818

Hi,
After upgrading from 5.1 to 6.0 my G4 got some issues.
First of all when i turn it one never turns the creen on. I had to do a work around using the USB cable to get the screen on and that doesn't wark very often eatheir so its preatty annoing.
Second the sim is not working.
I tryed many time to roll back or flash a new firmware but it didnt work.
I also find out when the phone is in download mode that is says LG-H818 but mine is fore sure a H815.
Is it some way to fix it?
Thanks

I just connected the phone to LGBridge and it notified the marshmallow update. I dont' know why it flashed a h818 rom
Does anyone know if there is a way to put the H815 firmware back? right know it believes to be a h818 so it doesnt allow me to flash it. WIth the h818 doesnt even turn on right now
Is ur phone recently repaired by lg or did u bought it used ? Cuz there is no way lg bridge can make mistake on ur g4s varaint...either someone u bought off tried to change the buid prop file to make u believe its h815 or ur phone is refurbished/repaired using components n sensors of other model
I bought it from a guy and the phone was totally new ( it had all the protection film on it and even the box was sealed).
I'm starting to think it was regenerated but i dont understand how could it be the dual sim one.
Do you have any suggestion how to fix it? right now i can just uplad h818 firmware from lgup but of course they are not working

Its probably refurbished ...if i were u i wont try to tinker any software things u might probably brick it so most probably leave it as it is good thing to know that atleast ur phone wont bootlooop like the rest...try contacting the person u bought it from or check it if its under warranty by lg from him
Right now its already rebooting aftern turning on, so i can not se how could damage it more. Any suggestion for possible solution?

Help [hardbricked device] urgent need of help asap

Ok so i was just rooting when my phone decides to die during so commands in adb. :crying:
Now i cant turn on the phone or boot into fastboot or bootloader. everytime i plug it in the charging light just flashes. Also my computer recognises the device as qualcomm hs-usb qdloader 9008 . ive read around the internet and ive found two methods. blank flash and qfil. issue is those tutorials were made for the moto g5 plus. I have searched around the internet and im beginnign to lose hope now. Can someone tell me how to fix this or give me the right blankflash version.
much appreciated
Im sorry that i cant post a useful reply for your problem that you cant even boot into fastboot / hardbricked phone.
The following link is for all those that are stuck in fastboot mode / boot loop.
This post says its for indian version, but i have EU version (1676) and it worked for me to get back my phone as it was when bought:

if you cant access bootloader take it to a repair shop - you need specialist software and hardware to re-image your phone
how on earth did you do that - you do know to root this device its just a simple zip flashing in recovery mode - no fancy commands or anything required once you have unlocked the bootloader via the very easy to follow guide on the moto unlock bootloader website

If you are using LineageOS all you had to do was just go into dev settings switch root to disable & restart the phone
If you used magisk just use the magisk uninstaller then reflash the kernel
I don't understand why you touched the bootloader partition

I dunno y either. Luckily I had insurance on it so now I got a new device
Although even though I'm sorted it think we need a way to fix hardbricked devices because the Moto g5plus and g4s have fixes but I haven't found any that work for Cedric devices

Hello everyone, it's been many months since I'm using the official LG v29a beta ROM installed with the booloader locked with LGUP.
I would like to go back to Marshmallow how can I do? My G4 is Italian no brand.

Cazzo... did you try the search box?
Doesn't matter. If I already lost a minute writing that, I can also advise you...
Flash V20p.kdz with LGUP. Don't forget you need to use the right .dll for the phone to be recognized.
If you use the search box you'll find what you need.

If you're stuck in LG logo boot up, just try to start LGUP (having the right files), connect the phone to a USB2 port and start the process.
Today, after try the RR ROM, I re-install v29a with TWRP but got stuck on the LG logo boot up, I just disconnected the phone from the computer, turned ON LGUP, connected the phone, was detected as it should and re-flash the v20p.kdz again. No problem... try it.
Can also see this: https://forum.xda-developers.com/showpost.php?p=76951541&postcount=30
Good luck.
