CyanogenMod 14 Lockscreen Bypass? Help? - T-Mobile LG G4

Hi everyone! So, recently I backed up my LG G4 running the 11-30 nightly and I had to backup and restore because I was messing with a few things on my phone. After I went back to CM14 and went to restore the backup it installed fine but it changed my pattern lock, so now I cant even get into my phone to turn on USB Debugging or Advanced boot. Im just stuck on my lock screen. Does anyone know how I could bypass that or enter into TWRP another way? Thanks!!

I had a similar problem. The solution:

In fact, it suffices to delete locksettings.db in /data/system. @codeworkx explained this workaround somewhere in the official CM thread.

Boot to TWRP by holding Vol Down + Power until the logo appears, release Power for 1 second then hold again until the factory wipe screen appears. Follow the directions to wipe (don't worry, this will not erase your data unless the stock recovery is installed.) After 20 seconds or so TWRP will load. Go to Advanced -> Terminal or File Manager to delete the file.

Unable to enter recovery mode after removing a system file by accident

Greetings. I ran into a major problem yesterday when i was playing around with titanium backup. I was a bit careless and touched some important system file. After which i was unable to reach the home menu nor restore the backup file. I rebooted and pressed the volume down button, and the "updating system.." icon appeared. Nothing happened for 1h, so i tried using the lg software suit to do a remote recovery. Nothing worked. I tried performing an update, hopimg the particular file might be restored, but the updater told me the new version is incompatible.
I'm a bit inexperienced in these matters, but i find it impossible that the bootloader could become permanently inaccessible due to a software error. I need to restore the original rom without accessing recovery mode on the phone - but how?
You're right, it's not possible.
You're trying to get into recovery wrong
Hold bother power and vol-, not just vol-

Thats what I thought I did, I always hold the power button until the boot screen appears. Still no improvement, seems I wont be able to restore my phone to factory default through normal means.
If you let it try and boot up, you might get it far enough to use 'adb reboot recovery'
If you ask me, the best solution is to flash the stock rom > root > restore titanium backup
As I said, there's no way I can reach any system menu whatsoever. The phone freezes at the LG logo on a normal boot, and in system recovery it freezes at "S/W Update". I can't do anything using the manufacturer's PC software, so what do I do? The rom is obviously rooted, but I'm not the one who performed the job so I don't know which software was used for that.

So how do I flash the stock rom? I can't get to the bootloader menu.

PSA: Unlocking Bootloader Before First Boot

Many people when they first get a Nexus device, choose to unlock the bootloader right away to prevent a mandatory data wipe if they unlock it later. Myself and a few others have encountered a bootloop after doing so. If this happens to you, follow these steps.
1) If your phone is stuck in a bootloop, Hold volume up, volume down & the power button until the phone turns off.
2) Wait a minute as trying to turn the phone back on may be unresponsive.
3) Hold volume up, volume down & power to boot into the bootloader.
4) Toggle to recovery and press the power button.
5) When you see the android laying down: press and hold the power button and immediately press volume up. It should open the menu.
6) Choose wipe data/factory reset. When completed the phone will reboot and should boot to the welcome screen
Hope this helps anyone who has this issue!
If I boot once, then reboot to boot loader then unlock will I be ok? I'm getting mine tomorrow.
Thanks for the heads up. I have no doubt that I will run into this issue and these instructions will help.

Yes.
Suppose that's from the update that happens when you first boot, we all know how well OTAs and unlocked bootloaders get along.

This is related to the typical Nexus data partition situation: If the data partition is wiped, the partition needs to be regenerated in some fashion before it can be written to, and this can only be done by booting once into the OS. Recovery and bootloader are unable to complete this operation alone.
If you find yourself in the situation of having wiped both system and data, you must flash any bootable OS version to system & boot via fastboot, and boot into it once, before you will be able to install ROMs via recovery again.
This is very important and I do this with every Nexus device on first boot.

This help, also had to format "data" because i skipped the first boot and installed the recovery right away
Thanks for this post
I booted mine straight to bootloader when it came and unlocked it with no problems. I wonder why this only happens sometimes?
did those of you who got a bootloop have to download/install the OTA when it finally booted?

[Q] Stuck in first Cyanogenmod boot?

Hi guys, first time posting here, sorry if a question like this has already been asked but I've looked around and haven't managed to solve my problem yet.
So I have rooted my Samsung Galaxy Mini II (GT-S6500T) and used Odin 3.07 to install ClockworkMod 6.0.3.2 onto it; I then booted it into recovery mode and installed ZIP from SD card, selected CyanogenMod 10.2 ("cm-10.2-20131202-UNOFFICIAL-jenad.zip"), followed instructions etc. installed Google Apps and all that.
Now, when I selected to start up the phone again, it just gets stuck in the Cyanogenmod boot screen, the blue arrow just circles around on and on (I understand that it usually takes a long time but I don't think it's meant to take over half an hour... also, every now and then I notice it kind of makes a low vibrate sound?).
I've read that to fix it you can reboot it into recovery mode and reflash it but the problem is I can't even get into the recovery mode. If I force the phone off (e.g. by removing battery) and hold Vol Up + Vol Down + Home + Power to boot recovery mode, nothing happens. If I just hold Power it starts up and goes straight into boot sequence.
I do have a backup of my previous settings and all that saved - one saved on my external SD card and the same file saved on my computer, so if I can somehow load that back it would be great I guess.

I mentioned earlier I cannot enter recovery mode. When I hold the button combination to go into it, nothing happens.
Earlier I managed to get into download mode (Vol Down + Home + Power) and I reflashed a stock firmware, but now my phone is stuck in a boot loop, it just shows the Samsung screen and vibrates every now and then. I still cannot access recovery mode.
Managed to fix the problem but thanks for the help anyway. Followed one of the solutions here and removed everything, held power for 1 min, plugged my phone into the computer and managed to get into recovery mode. From there I did full wipe, wipe cache, wipe Dalvik cache, format /system (probably only necessary to do full wipe but I dunno), then restarted into download mode and used Odin to reflash stock rom, then reloaded recovery mode and reloaded my backup.
edit: My question now is, I'm not sure what I've done wrong in the process of installing Cyanogenmod to screw up this badly. Is it absolutely necessary to format /system before installing it? I did do full wipe, cache and Dalvik cache and mounted /system prior to rebooting and loading Cyanogenmod.
what i do > install rom > reboot > install google apps .. I had this problem aswell a while ago. what also can be the problem is when u don't format correctly..

Have You as well was unable to go into recovery mode and stuck on bootloop ? One thing I can do is to use Odin, tried to flash some stock firmware with no result. Still no acces to recovery and still Samsung logo loop. I searched, read many topics but nothing helped. Is there something except Riff Jig that could be done ? Thanks for response
-Flash stock rom via Odin
-Flash cwm via Odin
-Pull out battery
-Connect phone to pc (without battery)
-Wait until screen turns on
-Hold recovery combo keys until samsung logo shows (home+volup +voldown +power)
-put battery back quickly
-You should be in recovery now :wipe data, cache, dalvik cache
-Reboot.
I was in similar situation, if not identical. This worked for me. Good luck.
Edit: I didn't see you fixed it already. Ignore the post.

[Q] Please help - bricked?

I have been tearing my hair out for like six straight hours now... so first I started with completely stock 12B.
Here is what I did.
1) Root using ioroot method
2) Install TWRP using FreeGee (which I'm now reading caused this entire mess god damnit)
3) Go into TWRP and format data to get ready to flash stock rooted debloat
4) Accidentally format sdcard so I have to get my rom zip back onto my phone
5) adb push keeps failing because rom file is so big so i flash a smaller size AOSP rom which boots
6) MTP transfer my stock rom zip file to my phone
7) go back to TWRP, wipe everything again (except sdcard obviously) and flash the stock rom
8) stock rom hangs at boot logo for ~20 minutes so i force restart, try again three times
9) go back into TWRP, TWRP starts not flashing things and telling me I have a partition error
10) TWRP isn't working for me anymore so I try a revert back to stock (verizon .tot) method posted here using LG Flash Tool
11) Fails twice
12) Phone has no more TWRP and only download mode
My questions
1) Is this phone totally screwed because it is the replacement I just got for my old one and I can't even unroot it to get another replacement (using manufacturer warranty, no verizon warranty)
2) Is there a way to get back to clean slate stock or even flash anything (TWRP, etc.) with only download mode available
I cannot function without my phone and I am very stressed right now somebody please help
EDIT: tried doing reset to stock KDZ method and it passed but when i reboot the phone i'm still stuck with only download mode, no recovery, and nothing past the LG logo. still the same....
turn on phone, see LG logo, immediately see download mode. now at least the LG logo doesn't hang but now it's the download mode,.

2) Yes, using the method you've attempted already. Make sure you validate your download and follow all the steps carefully in the guide.

I've repeated carefully with multiple downloads, but I deduce I have the following problems.
1) Partition error with TWRP caused by FreeGee and probably deleting my /sdcard/ partition or something idk
2) My attempts at returning to stock have removed TWRP in place of download mode for some reason so I can't do recovery
3) Something is wrong with download mode because it's not being effective in the .tot or .kdz return to stock methods
4) I don't even know what's going on anymore I'll sleep on it and come back tomorrow
thanks for the quick response. I think I'll just see if i can pin this on the replacement guys and get a replacement.

Then the flash tool didn't take. I've used it three times now and after the flash says its successful, you take the USB out of the phone and use the hardware keys to factory reset.
Instead of going to twrp as it usually does, it actually does the factory reset. If you don't do that then it bootloops till you do. The flash tool doesn't remove everything to make it factory stock.

I doesn't seem like you're pressing the right button combo to get into the Factory hard reset menu.
Do this:
1) Power the phone off completely (press and hold the power button until the phone shuts off).
2) Press and hold the power and volume down buttons at the same time.
3) When the LG logo comes up on the screen, let go of the power and volume down buttons, then press the power and volume down buttons at the same time again until the Factory hard reset menu comes on the screen.
4) Once in the Factory hard reset menu, press the power button twice to factory reset the phone.
If you already knew this, then I apologize.

Yeah, when I do that I get the download mode "firmware update" screen. previously it would lead to TWRP, but now it leads to firmware update screen.
ty
New update: I finally got 11A .tot to flash, but booting it was really unstable, kept rebooting / blank screen of death like every time I tried to get in. Finally became slightly more stable when I took the SIM card out, used WiFi to download 12B update using OTA. Installed OTA and now it's hanging at the "Updating software 2/2" page at 35% (the page with the beautiful picture of the lush green grass and the blue sky). I'm just going to leave it for a night plugged into the wall and see where it goes, maybe it's frozen, maybe it's not.
Probably it is. In which case I'll probably have to force reboot and I'll wake up to a host of new problems.

[q] lg l90 d415

After downloading CM11 and GApps, I put it in my SD card and went into my recovery cwm9 by using an app. I got in and tried to flash my zips but I couldn't find them. Before I actually tried to flash them I did this first:
Wipe cache ( only required on first installation )
Wipe Dalcik cache ( only required on first installation )
Format /system and optionally /data ( Only necessary if coming from stock or a different ROM )
So when I rebooted I was greeted by getting stuck at the T-mobile boot splash.
I don't know how to get into recovery manually. I can't try to use download mode because I used fastboot. When I get into fastboot I tried using ADB to boot into recovery but device is not found when I'm in fastboot.
Please help me, I literally just got this phone and wanted to flash a custom rom because the LG stock is disgusting.

See FAQ thread for getting into recovery.
[SIZE=+1]Q14: I've flashed a custom recovery but what are the key combos to get there?[/SIZE]
Power off the device
Press and hold Power + Volume down
When the LG logo appears on the screen, quickly release the Power button, still holding the Volume down button, and press and hold Power again until the "Factory Reset" screen appears. Don't worry, this won't reset the device.
Use the volume keys to navigate up and down and Power to select. Scroll down and select "Yes" and repeat once more. It may take up to 10 seconds for the device to boot to recovery.
I've now gotten into the recovery and installed both cyanogenmod and GApps. I've actually had to change the rom found here:
http://forum.xda-developers.com/lg-l90/development/rom-cyanogenmod-11-lg-l90-lg-d415-t2871371
I've had to change the updater script that contained "w7" to "w7ds" because it said my device wasn't w7 and that it was w7ds.
I've rebooted and now it's just stuck on the cyanogenmod boot screen.
What do?

You've got an older recovery it seems. Download Philz-Touch from my thread, the link you posted, or get TWRP from this thread
Since you're having booting issues, use fastboot to flash the recovery.
Thing is when I'm in fastboot, ADB won't detect my device. I've only gotten it to detect my device once and that's when I was unlocking my bootloader. I don't know how to do it again.
So what do I do? BTW, thanks for helping me.
Edit: I formatted everything again and tried to reinstall the cyanogenmod and GApps. Seems like I just had to wait for the boot screen.

Put device in fastboot mode. ADB can't detect the device when it's in fastboot mode.
Type:
Code:
fastboot devices
You should see a listing similar to "adb devices" output.
Copy recovery image to the same folder fastboot is in. Then type:
Code:
fastboot flash recovery recovery.img
or
Code:
fastboot boot recovery.img
First one will only write the recovery image to the device. The second on will write the image to the device and should then boot the device to the recovery.
EDIT:
Yes, the first boot takes a couple minutes.
Seems I just had to wait for bootscreen.

easiest way to explain. Go to Settings and toggle Mobile Networks off/on.

Well, yeah, but a faster way. Like in LG in the notification bar there was a button that would turn data on and off. Does cyanogenmod have anything like that similarly?
