Dear all,
Thanks for reading this post first. I have a G3 D855 with a unknown ROM inside (as i bought it from others, i don't know what the ROM is, but it is obviously a custom ROM). I try to flash a stock ROM and search the method from the net, but no method i can use for the following reasons:
1. i can't go into download mode (tried turn off phone, hold volume+ and plug in cable method)
2. i can't go into recovery mode with any key combination (used the method online, the screen will light up but LG logo won't show, there light off, keep looping like this)
3. i can't hard reset with any key combination
4. as you can see above, i can't get into fastboot mode with any key combination (but i do can use program in Win7 to call the phone into fastboot mode)
5. When i connect the phone (turned on) with Windows 7, it can recognised as LG G3, and i can explore the internal storage. But if i try to connect it for the Download Mode, then it can't be recognised, just "dang dang" sound from the computer. (i have installed the latest LG drivers). My phone can't be recognised in Ubuntu.
So, i try to figure out what has happened to my phone, and after searching for few days, i believe that i may flash sbl1.img, aboot.img, rpm.img, tz.img to get back the above modes for my phone (see http://forum.xda-developers.com/showthread.php?t=2582142). I would like to know if my thought is correct at this point.
If yes, can i just make my phone into fastboot mode with the help of the Windows Program to flash back those img, or can i use Flashify to flash those image?
Thanks for all your help.
hello geeks,
I really need serious help. First the setup I have is as follows
1. I have LG G3 D855 but its european or Hong Kong or Taiwan version I don't know. I bought it in India. I updated it to android 5.0 Lollipop. Everything is fine till now.
2. Then I rooted my phone. This step was also fine. No problem.
3. Then I tried to download camera mod v2.0 to get some extra camera features like 60fps. In this step I got problems. I downloaded the media_profile.xml and copied it to /system/etc. But I made a mistake that I did not change its permission and rebooted the phone.
I am troubleshooting from a windows 8.1 PC. I downloaded the LG USB driver.
Due to this my phone stop at initial LG,Life is Good Screen. I tried different methods in internet.
1. I tired to access the device file file through adb. But the adb does not list the device.
2. I tried to use fastboot mode, but still fastboot does not list device when in the boot screen.
3. I pressed down pwr + volume down button and release after screen come up and then press again. I was asked to erase user data. I said yes and it erased the data. But still the same symptom when I reboot. Stuck at initial screen.
4. I tried to use LG PC Suite. But it does not even detect phone through the USB and there is no repair button.
5. I tried to enter downloading mode. This one is strange. I pressed down the vol up and then connected USB. But sometimes only it enters downloading mode and sometimes not. May be once in 10 times it enters downloading mode and 9 times it goes to initial boot LG screen.
I am not sure whats going on. Can anybody help me to figure it out ? Please help.
Thats because your not doing it properly
Research a guide on how to enter download mode and after that you can use flashtool to wipe your system and reinstall the original lg firmware
I have just flash the custom 5.0.2 ROM using philz touch 6.48.4.
After I flashed the ROM, I reboot to the philz recovery and flashed back to cwm 6.0.4.8.
However, the device stuck on the LG logo screen.
I have try to enter Download mode/Emergence mode/Hard reset mode/Recovery, but all of them I cannot go into.
Please help! Thank you for your helping!!

Your boot loader is broken. Gonna have to get to the down load mode and reinstall either the or the stock. You can probably flash the recovery with .IMG file with lg flashing tool. Nerdy blond's twrp is one of those files that you can use. You can even try installing it first with the adb shell command, you can get the instructions at the same place where you download.

Thank you for replying.
I cannot do anythings since I cannot enter into download mode.
I pressed volume key + and - and insert the usb cable to computer. There is nothing happened, computer dose not show the devices attached and the phone stay in the LG logo screen.
Also, I cannot use adb commands to force the phone enters into download mode as it shows nothings under "List of devices".
Is there any methods I can go into the download mode???
Thank you!

If your phone shows LG start screen, it should go into Download mode. I had similar problem few days ago while I was testing some kernel patches, it just froze on the LG screen. Solution was to unplug it, remove it's battery, SIM & SD (you don't have to remove SIM & SD, I just work that way) , make sure it's off, return battery back, press Vol + & Vol - at the same time and plug-in the USB cable.
Before that, make sure you have installed LG Unified driver (can be obtained via LG's software from support site), because without that Windows won't recognise your device.
After that, once you make your phone usable with Freegee/whatever you use to install initial recovery, flash official TWRP, because others are too old - that Philz CWM is old but still working with Lollipop but not work good and is tends to lock itself into a bootloop if you use hardware keys to enter; that other one, from GPRO_recovery APK is not supported and not working well (for me since day one), so it should be replaced as soon as possible.
Also, I can suggest you to flash your phone from stock 4.1 (not KitKat), root, flash recovery via freegee and after reboot update to latest official TWRP via Flashify.

Thank you for your detail reply.
I have tried to reinstall the LG driver and try to enter download mode again.
The screen is still stuck on LG logo and I cannot find the device in hardware manager (cannot recognize it).
I cannot do anythings until it can recognize it.
(Is it the bootloader is broken? and can I fix it?)
Thank you very much and waiting for your reply soon.:good:

Which version of Windows are you using? It should be displayed under Serial ports in Device manager (named something like LGE Serial device) and LGFlashTool should recognise it immediately. I can't make you a screenshot/check for real name because I'm running Linux right now and can't reboot.
Also, try with another cable/port, remove all other android drivers you may have (Samsung's, Google's...) and disable antivirus.

OK, it doesn't enter download mode. So, step by step:
- remove battery and leave it for 15-30 seconds, return battery
- press Vol+ and Vol- at the same time and keep them pressed,
- plug USB cable in while keys are pressed
It should immediately put you into download mode, with no LG screen, just black screen with gray box and red text I've described to you.

So, whatever you try to do, phone just shows LG logo, not even a message in an upper left corner?
I'm running out of ideas. I have exact same variant (E988) but only time it didn't want to enter download mode this way was when cable I was using was broken...

FIRST install the DRIVER from this thread: http://forum.xda-developers.com/showthread.php?t=2785089
See in the part 2015 with TOT files...
(if any other drivers are present, uninstall them and do a clean install)
You need to get in Download mode to be able to fix it without having to open the phone.
1. Unplug phone from pc and power off
2. Remove back cover and remove the battery
3. Plug the micro-usb cable into the phone
4. Press and HOLD the VOLUME DOWN (make sure you press it from the edge, far from the powerbutton)
5. Put the battery - Dont let go of Volume Down yet.
6. Connect the micro-usb cable to the pc - Dont let go of volume down yet
7. Wait for the pc to recognize it, and the download mode appears on the phone, now you can let go of volume down
Repeat again, first time might not work.

PS, quote me because i might not see and answer then. good luck
I do not know in depth about all this stuff, I've just been thrown into it because my phone decided to brick itself in a system update after it got into my hands. I updated it and it went into crash dump, a few times, the just nonstop boot looped with the oneplus logo on, and some pixels bugging, then it stopped showing the oneplus logo all together and just boot loops, I can go into fast boot and nothing else, if I restart bootloader it now goes to a charge menu and rarely actually restarts fast boot, I just tried msm and I've tried booting into twrp but it wont work, i believe this is because the phone wont connect to my pc properly but i have tried universal adb drivers, new sdk, and official QUALCOMM ones to all get the same result of appearing in device manager as just andrioud and nothing else with no options for drivers, on msm it would show up but it wouldn't get past waiting for device. also i cant find a proper twrp rom for the 9 pro on here, atleast the stock one, nor can i find it anywhere else, i can only find the img. also i feel I'm missing something with flashing on the fastboot and am not seeing if I'm supposed to be doing something (of the limited things i can do) on the phone, or its all in commands and stuff on here. sorry this is horribly written, I'm tired and stressed because of this.
Search stock rom and download
unzip rom ,connect your phone in download mode and flash STOCK ROM.

You shod download "EDL" tool (even called MSN)
unzip and exetute ad admin (read specifications and troubleshooting in the related thread)
ensure tour phone is off
press and keep both volume buttons while connecting it to PC
then the COM X connection should become "green + connected"
go with "start" and just wait the processo to end

Download mode is not vol up + power, that's bootloader
EDL (Download mode) is both vol buttons + power
It should show up in the device manager on the computer as a Qualcomm device if it's worked correctly.

EDL mode is NOT both Volume buttons + Power, it's just HOLDING BOTH THE VOLUME BUTTONS and WHILE HOLDING THE VOLUME BUTTONS, CONNECT THE USB CABLE. The phone needs to be in a switched OFF state before doing this.
By holding both volume buttons and the power button, you will force restart your phone into bootloader mode (fastboot mode).
And VOLUME UP + POWER BUTTON is recovery mode.
