[Q] Can't access recovery mode via hardware, only via software - G3 Q&A, Help & Troubleshooting

Hi guys,
I have a F400L which has been giving me all kinds of havoc. Not sure what the main problem is but it constantly reboots, wifi and bluetooth don't work and I can only access recovery mode via using an app like Flashify (hardware buttons do not work).
Might have something to do with using a modified dll file from this thread http://forum.xda-developers.com/showthread.php?t=2799703 (my f400L thought it was an f400k and i couldn't flash the normal f400l dll file)
Please I need HELP

I think the only thing you can do is flash the KDZ for it. If you can still get into download mode flash the KDZ using CSE Mode which will wipe all partitions and rewrite the correct ones
Why didnt you flash the KDZ instead of using the DLL+TOT Method?

Just tried that. Unfortunately still having issues. Doing a bit of searching and it appears similarly to what is happening in this thread https://productforums.google.com/forum/#!topic/nexus/X6ZjAAauATc[1-25]

So just to be clear
You flashed the latest KDZ for F400L using CSE Flash Mode in LG Flash Tool? Is wifi and bluetooth fixed?

Try THIS tutorial to flash your kdz.. Also it's wierd because if you succesfully flash an kdz file (using any method) you should be completly (re)locked and unrooted.

i can barely remember what i was doing, im sorry
if you come from 4.4 you can flash through the lgspst from the teenybin thread the 975 kdz file by renaming it to bin, and then because you are with the ls970 dll file, you can root it, flash cwm through freegee then go to cwm and clear everything (data cache sddata system dalvik nothing else) and then go to download mode again and flash the original e975 kdz through the kdz updater, its a lengthy process but thats how i did it until i or someone else find another more short way

How did you try to get into download mode? Twrp can boot into download mode and also did you try the manual method to get into download mode?
Also how did you you flash the kdz because technically when you flash a kdz it should wipe twrp recovery and return you to stock recovery.

Internal storage is empty and the download mode don't go, I flashed the same firmware for unroot the phone but don't go. I've tried doing this http://forum.xda-developers.com/sprint-lg-g3/general/guide-fix-hard-brick-recovery-guide-t3132359 and the phone goes.

Stock Marshmallow rom needed urgently - H815 20E

My G4 has just gone on me again, just sitting at the boot logo and a flashing blue led. This is the 2nd time in a week and the last time it was due to a corrupt build.prop, which I was able to replace from backup. This time it has just happened randomly and the original build.prop doesn't help.
So if someone can help me out urgently with a stock marshmallow rom for twrp it would be a big help.
Cheers.

theres is softbrick and bootloop. you are aware that G4 can bootloop do to a hadware issue not software.?
maybe you have infamous bootloop. and not a soft brick. but you can try to KDZ does it boot into twrp.? if not then hardware issue.
for kdz search here to flash using LGUP.

Yes, it boots to twrp. Thats the reason I need the 20e zip file and not kdz. I was able to flash a 20d zip last night which then allowed me to flash the 20e kdz. But when I flashed twrp again just now, the same thing has happened again. I'm thinking now that this started happening when I updated twrp to the latest version via the twrp app, and it was only when I had another app crash and reboot my phone two nights ago that it happened for the first time. I'm going to downgrade twrp to an earlier version and see if that makes a difference.

??? you needed the zip to flash KDZ.??? that makes no sense.. then no hardware issue just a soft brick, a software issue. all you had to do was KDZ to latest version. using the refurbished option on LGUP.
then inject twrp and install twrp permanently and then root .
wich twrp are you using.? have you tried this.
the unnoficial beta5.

I was unable to boot my phone so I needed to reflash it. As I only had access to twrp, I had to flash a zip file. I couldn't find a 20e zip so I flashed the next best thing, which was a 20d file. This isn't the correct version for my phone and let me know that each time I booted it. So once I had the phone booted up, I used LGUP to flash the 20e kdz file. My reasoning for this is that I can only flash a kdz file using LGUP, and as I can't boot my phone, I can't use LGUP. So are you telling me I can flash a kdz file from twrp?
Anyway, it appears the latest twrp (twrp-3.0.2-1-h815) was causing the problem. I reverted back to the previous version and I have had no issues so far. I've taken a full nandroid backup to be on the safe side.
Thanks for the advice.

if you boot to twrp then am pretty sure you can enter download mode and use LGUP and KDZ. that was my point. its even better as its the official firmware that will fix any issues..

I couldn't get the phone into download mode. If I had been able to do so it would've made life a lot easier for me. Flashing the zip file and then the kdz was a long winded way to do it but I finally got the desired effect. And I was able to tell that the latest twrp looks to be problematic for the H815 (I've prepared myself for any resulting backlash).

give the one i posted link a try.. is unofficial and at the same thime official..
Just disabling automatic updates in your rom should fix all this. Latest twrp works fine.

1) Which way are you trying to flash back to stock - kdz or tot? If tot is failing then try to kdz, if kdz is failing then try the tot restore...here's a guide with all you'll need for either flash method: https://forum.xda-developers.com/showthread.php?t=2785089
2) Try using the original LG usb cable if you have it and use a usb 2.0 port while flashing.
If you have download mode one of those flashing methods should work for you as long as you have all the drivers installed and the correct files to flash.
Good luck :good:
