Hello, I'm attempting to fix a G2 for a friend, which hasn't been able to connect to Wi-Fi, and in addition to said fix, they wanted CyanogenMod for the phone as well. I've had no such luck after a factory data reset, flashing the ZVG Stock ROM when Download Mode was available, and getting the phone to use apps such as GeeFree have been unsuccessful to flash TWRP. When I try to enter Download Mode now, the LG logo appears for a bit, but then shows the charging animation. Recovery mode is still available, and I can wipe the phone from there, but still no Download Mode. The phone currently can power on and function as normal, but Wi-Fi cannot be used, and there isn't any root access. Any help is appreciated!
UPDATE: I've successfully installed CyanogenMod, however I'm still not able to get Wi-Fi working at all. And the issue I had with Download Mode was that I used a bad cable. My apologies.

Sorry, I'm relatively new to rooting and I looked through the threads and found similar problems, but none that seem to exactly match mine.
I have a rooted VS985 that I was trying to flash with the AndroidNow HD 6.1 ROM using TWRP and I guess the flash tool crashed. It was stuck on a black screen for an hour or two so I hard reset it and after that, the phone will only flash the LG logo for a second before the screen turns off and the indicator light alternates flashing red and blue. As far as I can tell, the computer does not detect it when it is in this mode (seems similar to the secure boot issue that some people have been having). I cannot enter download mode (the LG logo flashes on and the indicator light flashes blue once and then both turn off) but I can still boot into TWRP Recovery. When I try to boot into download mode, even while the screen is off, my computer detects the phone as QHSUSB_BULK. Also, when in recovery mode, my computer can detect the phone as a G3 and I can access it with adb tools but I don't know where to go from here. I have tried using the LGFlashTool but I can't seem to access the phone because it will not enter download mode and I've tried reflashing AndroidNow HW 6.1. The flash completes and says it is successful, but the phone still will not boot properly.
Luckily, I got the phone a few days ago from Costco, so there is a good chance I can still return it, but I would like to fix it if I can.
Any help would be greatly appreciated.

You said you have adb working.
Did you make a backup of your stock download mode at anypoint of time? (Iaf.img)
I guess it can be pushed back using adb, but am not very sure. Even if not, maybe you can take the stock Iaf.img from someone else and try pushing it via adb using this command:
Code:
dd if=/storage/external_SD/stock-laf.img of=/dev/block/platform/msm_sdcc.1/by-name/laf
Then you can boot into the download mode using the command:
Code:
fastboot boot stock-laf.img
It doesn't look like I have the stock laf.img backed up. I'll try to get it from someone. Thanks, I'll let you know what happens when I get it.

hi guys
so basically i installed some roms on my note 2 but i didnt like them so i reflashed note 2's stock firmware.
when i got the phone i wasnt able to go into download mode, the problem was i could go pass Volume Up: Continue
once i reflashed the stock rom i waited for it to boot, ive dealt with difference samsung phones and from my knowldge it wont boot until i do a full wipe after the flash. i pulled out the battery and tried to get into recovery but it wont go in it.
i used adb to go into download mode and recovery mode before since it was the only option. but now i cant because it doesnt recognize the device. odin detects the device when not in download mode but wont do anything. i really need help guys.
thank u i hope someone can help
Hello all,
I have downloaded CM 12.1(Lollipop 5.1 09-10-2015) to install. Then I tried recovery mode, got secure boot error. I don't remember the page, but from here in xda, I found some solution, which I entered some codes to code terminal involving aboot.img. Somehow it worked and I used TWRP to install CM 12.1. It works fine.
Then I wanted to go back to stock, downloaded LGFlashTool. Problem starts here. When I tried to enter download mode(volume up) it installed the driver to pc. Then my phone went to download mode, but on top of the screen there was "Secure boot error" message. I looked into driver installing at first and it was qhsusb_bulk.
I have searched on xda and over the internet then, but I didn't find a solution. All the solutions for completely gone G3s.
To sum up, my problem is I can't go back to stock ROM because of the secure boot error in download mode. TWRP recovery works, I can use my phone with CM 12.1 Nightlies Android 5.1 but I can't go back to stock ROM since download mode is not working(secure boot error). I have .kdz file, and now downloading 2.1 GB tot file(not sure where to use). I also have bootdiag, which may be a solution.
I really want to fix it and go back to stock. Any help appreciated.
Thanks in advance!
What I've done:
1. Tried LGNPST method but phone never showed up in the software
2. Tried flashing with LG official tool. That always resulted phone disconnected.[I did put my phone into download mode]
3.Tried almost all KDZ_FW_UPDATE methods they always stopped either in not responding-> close program OR extraction error
4. Tried sideloading using adb but they also resulted in "bad file" even push didn't work saying no permission to write(I think)
for adb I tried converted .zip of kdz using some guide in xda.
My phone is totally clean now. I can boot to Recovery or Download Mode. There's no file that's flashable right now. I'm in Philz touch recovery
This actually happened while I was flashing to unlock bootloader and charge went low.
I desperately want it to function properly. Please anyone with any new or updated methods, help me.
When normally trying to boot up, Google logo comes and phone switches off.
I was in F180L converted to E975.
I've INDIAN(20a) version kdz also european(10h) and korean(30e).
Hi Folks,
I have a Tab S 8.4 wifi that I seem to have broken. I was attempting to restore the stock Marshmallow rom and something has gone horribly wrong. This is what I did:
1. I installed the latest stock rom by Odin and booted
2. I then downloaded and installed CF auto root/TWRP for the SM-T700, however, I failed notice that I had left NAND erase checked in the Odin settings so now all I get is the device attempting boot into TWRP which doesn’t work.
The device won’t turn off to allow me to use the buttons to access download mode which I know is what I need. I have tried draining the battery completely but as soon as power is restored it attempts to boot into the failed recovery again and is, in effect, stuck on the TWRP screen, periodically flashing the screen. It its broken TWRP state, the computer recognises it as a USB MTP device but will not recognise with the correct drivers to allow me to use ADB to force it into the download.
Does anybody have any suggestions? Otherwise I have a £250 paperweight!

The file you flashed doesn't work on Marshmallow.
Use the updated twrp and supersu in the dev section.

Thanks for the reply ashyx, I don't current have a way to achieve that as I cannot access download mode. Any suggestions on how to do that?

You can access download mode anytime irrespective of the current state the device is in.
Hold POWER + HOME + VOL DOWN until the device boots in to download mode.

I did't realise it would work in any mode!
Thought I'd tried it but obviously not held long enough.
You are a star! Thank you so much.
