[Q] HELP: need different ways to get into recovery

I'm having a serious problem with my note 2.
I'm running omegaromv30, and for some reason i seem to encounter a returning error (com.android.systemui stopped working) and it keeps looping. Normally i just booted to recovery and reinstalled omegarom. But now i have another problem on top of that which is that my power button died and is unusable (ordered a new one).
So i cant boot into recovery with the 3 key combo, i cant boot into recovery with the use of some app, becasue my phone is unusable with this error loop. I'm trying to use adb, however it tells me "device not found". I'm not sure if it should find my note 2 when it isn't in recovery mode and is having some error loop. (edit: found out that i must enable usb-debugging, which i'm unable to do) I really need to get into recovery mode to fix at least this error.
Any tips how to get into recovery in a different way?
Or how to enable usb-debugging without being able to go into settings...
many thanks in advance!

D855 Softbrick. Can't seem to fix it. Help.

Current situation: I'm currently stuck at the "firmware update" screen when I turn the device on.
What I think I did: I think I messed up the partition file or made a mistake trying to install twrp custom recovery
What happened: I did a factory reset when I got confused at one point and that worked as it should. When I tried it again, I was stuck in/at fast boot. However, doing a battery pull would boot the phone up. Recovery was damaged somehow?
I tried putting the phone in download mode to flash it to fix this issue. I did the method where I change COM5 to COM41, use flashtool to flash a tot and dll, pulling the usb out and reinserting when the program says "ready" but I get an error: Partition Change fa00000064 and hence that process fails.
LGPCSuite doesn't work.
Any idea how I can rectify this issue?
Thanks in advance.

LG G4 H81510h download mode not working

Hello Gurus,
Well i am trying to boot my phone into download mode but i am continuously getting
secure booting error 1014 and my phone then boots lollipop 5.1 which is stock rom.
my lg g4 model is h81510h build number lmy47d, it is not rooting or flashed anyway.
I want to flash flash marshmallow kdz with lg flash tool but my phone is not booting into download mode, please help or suggest any other method
HALP PLS
I'm having more or less the same problem. I bought a used H815 and it came with Android 5.1 (software version h81510h)rooted and stock recovery. I tried upgrading to MM over OTA but tapping Update Center leads me directly to the App Update screen instead of giving me a choice between software update and app update.
That is when I decided to go the KDZ route but when i tried switching the phone to download mode it went there and in the top left corner there was this 'Secure Booting Error 1014' message and then it restarted in about 5 seconds. I have tried this multiple times with the same exact result.
ADB detects my phone but when I send the 'reboot bootloader' command it just does a plain reboot so I can't use any of the fastboot commands. I also have no idea whether this phone has an unlocked bootloader or not.
Also for some weird reason my phone is not using the MTP mode when I connect it to my PC. It either uses PTP or charge-only depending on what I select but if I select MTP it automatically reverts to the previously selected mode. LG Bridge doesn't detect it and neither does the Mobile Support Tool but I can transfer images just fine. MTP was working last night but it suddenly stopped working and I have no clue why.
I can get into the recovery without any problems.
Please help me get it working again

Im having the same problem.
Lg bridge, lgup and flashtool not detecting my phone. How to flash my phone with any os? Kindly help me
Same problem with my H811. Any solutions?
I cant get my g4 into download mode. I was able to earlier but it died on me. My buddy has the same phone so I am using his fully charged battery now (mine was around 40$) but I'm still getting nothing. Should I reformat the SD card and try again? I can't think of anything else.

Stuck on TWRP Recovery mode (LG G3 d855)

So after accidently wiping everything I had on both SD and Internal memory trying to make a custom rom work, I was stuck with a phone that only has TWRP on it, basically. Now after I've been through this guide TO THE LETTER: http://www.droidviews.com/install-stock-android-marshmallow-lg-g3-d855-using-twrp-recovery/ I can see it installed an OS but I cant seem to get my phone to load it! SO then I tried entering recovery mode and getting back to default, it didn't change anything, so I tried installing Zoe rom (https://forum.xda-developers.com/lg-g3/development/zoe-rom-v1-0-mm-6-0-stock-v30a-d855-t3402087) and It STILL ONLY LOADS TWRP even though the installation seemed to be successful!
So what do I need to do? Just flat out delete TWRP? or what? Pleas advise as I'm desperate. If needs be, redirect me to how to just completely reinstall everything from scratch to 6.0 or 7.0 (preferably). I was on 4.x.x for ages and I just wanted to update, instead destroyed my phone. Sigh.
UPDATE: Another thing I've tried is to flash it with KDZ file from the PC. I can see the phone, I can transfer files to it, but windows DOES NOT recognize in the device manage so when I tried to use the flash tool, after clicking "Start" it pops a new window which gets to 60% and then stops saying the phone is not connected to the pc.

I just got over something like this this morning. First, you need to ensure you have the LG Universal drivers installed for your phone. Get them here.
Next, reboot your machine.
After this, I made sure the PC recognized all 3 modes of my phone, TWRP mode (boot to TWRP, connect), Download Mode (boot to download mode with cable) and, at least in my case, the flashing lights mode (shows up as QHUD Bulk or something).
After that, I ran the KDZ restore program successfully.
Good luck and let me know how it goes.

LG G3 F400L Softbrick. Download mode available.

Hello everyone reading! I've tried many guides here, but none seems to work for me somehow, thats why im writing this post.
Whats my problem?
- I've been having this problem for a year or so now, like most softbricks im stuck on a bootloop while launching the phone, with red and blue led light flashing.
The message displayed in the top left corner of the screen says:
boot certification verify
Secure booting Error!
Cause: boot certification verify
How i have bricked my phone?
- I remember i have tried to unroot my phone after having cm installed, can't remeber the version though. Then the phone just got stuck in the bootloop and wont launch along with recovery.
What have i tried?
- I have tried flashing the phone to stock via lg flash tool (tot and dll) and Lg Flash tool 2014 (kdz) no luck unfortunately.
- While flashing stock F400L rom through tot files im having sometimes Milkyway connection failed error when im launching the program, but i don't think that's the case.
I'm doing everything in right order, drivers and programs installed, going into download mode, changing ports to COM41 or COM1 (neither works), launching lg flash tool 2014,
choosing suitable for F400L stock dll and tot then launching the process, unplugging the phone and after 5 seconds plugging it again.
Nothing happens, im stuck at ready.
- Tying to flash through kdz file seem not to work either, got errors after l start the flash process.
Phone plugged, in download mode, yet i get the message of program not being albe to access it, like it would have problems with connection to the computer.
Im following the instructions that program gives me though it does not help at all. It stops after reaching 4% and asks to connect the phone back after checking connection with the device.
Thanks for any help provided!
