[Q] LG G2 bootloop, No recovery mode, only download mode

Hi guys, (LG G2, Rooted, had twrp but now its vanished?!)
I managed to get my LG G2 into a bootloop. I was replacing bootanimations and rebooting and testing them out. I finally tried this 1080p boot animation that looked sweet. Once the device rebooted it would show half the boot animation and then reboot. I had twrp installed but now every time i try to access it it just ignores the hotkeys as if it doesn't exist anymore. I can only get into download mode if a usb is plugged in.
All i need to do is flash TWRP again so i can flash the stock bootanimation back. I do not want to do a fresh install as I have many important files (i know i should have backed them up). I have tried to access my phone via adb using windows commandline tool whilst in download mode. however, adb doesn't find my device (I was going to attempt to push the stock animation back).
Please help me guys i need my phone to be working by monday as i have work! thanks in advance

1. If you connect your phone to PC, what happens?
2. I also had trouble accessing TWRP, so I did the "Factory reset" button combo (Don't remember what it was) and when I slided to confirm, twrp booted. From there I think you have adb and can fix everything.

To get to TWRP, hold the power button until the phone turns completely off, then turn on the phone while holding the power and volume down buttons, then when the LG logo pops up, let go and re-press those buttons. When prompted for a factory reset, press the power button. Works every time for me.

Alone i used lg flashtoolnow,its ok. I didnt click factory reset i assumed it would delete everything? With lgflash i have restored system and everything is how i left it.

First off, you'll need to make sure your phone isn't plugged in or it won't work - I'm afraid if you can't enter recovery you'll have to go back to stock. http://forum.xda-developers.com/showthread.php?t=2432476

Try to flash the Kitkat baseband or if you are fully stock then i suggest you to flash the KDZ to go back to full stock(http://forum.xda-developers.com/showthread.php?t=2432476)
If you still have important data like pictures or what then do normal flash. Use the Android version you also had as stock and use that as KDZ. If you are not stock then can you reach TWRP?
and what did you do before that causes the black screen?

Stuck with the LG logo. Nothing happens in download mode
Hi All, not sure if this has been answered prior. This is what happen, I wanted to flash SOKP so I backup my phone and saved to PC using Titanium. I have TWRP installed.
Boot Into Recovery Mode and Wipe Data,System,Cache,Dalvik
I restart so I can flash the SOKP Rom and all I see on my phone is the LG logo. I try to restart using the Power and Up button, but it just sits in the download mode saying "Firmware Update" with no movement or action.
The phone is unable to turn off now. This is my first go at Flashing a Rom. Any help or suggestion would be greatly appreciated. Thanks in advance

Hey, I have the nearly same problem with my G2 running CM12 also installed recovery
But I can't reboot in recovery neither with the factory reset buttons, nor manually with SDK Manager, because the device is not found.
So I can just reboot and it shows the CM boot image, or get in the download mode.:crying:
Any suggestions?:fingers-crossed:

Help!!
I have boot loop, only download mode accessible, device not found on adb. When I try LG FlashTool, instead of using the KDZ file I provide, it starts downloading some other firmware at times, and at times it says your software is up to date. What do I do? :|

USE method with .tot is working for me

messed up trying to root

MODEL: SM-G900V
hello i messed up my phone by trying to root it, i used a random md5 that someone online said would root it with odin under "PDA" and now my phone will only load into recovery mode
i tried wipe data/factory reset and clear cache neither of them did anything
i tried doing it through kies and doing Firmware Upgrade And Initialisation but i couldn't even get my phone to connect to kies OR my laptop except it attempting to while the phone was starting up,
and when i tried to enter my S/N after my model number it continuously told me it was wrong
and i've tried loading a normal rom into my phone through odin and i couldnt because like i said, it'll only load into recovery mode, not bootloader..
but i think at first it could load into bootloader, but now it can't? it's hard to remember since ive tried so many different things in a very short time
if anyone has any idea how to help me, i'd appreciate it so much! please try to write simply if you can because i am a noob,

You don't need to go into bootloader. You should start with download mode which is accessible by holding vol dn home power.
If that doesn't show up, try taking off battery for a short period of time. If it boots into download mode your good to go.

ah it worked ty!! (incase any1 is here needing help later) the complete fix for it was taking out the battery for like an hour, holding down volume+power+home, plugging it into pc, using Odin3 and a clean rom of my version from sammobile.com, then pressing up volume+power+home again

Note N900w8 Stuck

Hi, so the problems I am experiencing are that I tried to install Resurrection Remix ROM for my phone. I do not know where my idiot brain messed up along the way, but I installed ROM Manager on my phone, and then pressed backup current ROM, which immediately set the phone to be booting in Recovery Mode, but unfortunately wont be detected my phone. The error code is the following:
RECOVERY BOOTING:
RECOVERY IS NOT SEANDRIOD ENFORCING
Set Warranty Bit : recovery
I tried pushing the VOLUME DOWN + POWER and the HOME buttons together to open Odin mode, but this is just stuck, as nothing happens in that mode. After several hours of trying to figure this out by myself, a frustrated me decided to come here to see if the community could help me out. Does anyone have any ideas? I really cannot afford a new phone right now :crying:

Flash twrp in odin mode.

Do you have access to a USB jig to try and force download mode?
Before pressing vol down, home, and power, is the phone powered off?What do you mean nothing happens? The phone won't power on?

Fixed, thank you for your help

What I did to solve the issue was flash a stock Andriod 4.4.2 tar file from Odin. The computer would not recognize the device sometimes, however, I did manage to get it through. After that I managed to get everything figured out and get Reserruction Remix ROM on my phone. Thank you for your guys help!

Recovery Is Not Seandroid Enforcing

I tried to root my phone S7 Edge 6.1.1 just a moment ago using ODIN and CF Auto Root. I got the PASSES! sign in ODIN but upon phone rebooting I am stuck on the Samsung S7 Edge logo screen with text in red 'Recovery Is Not Seandroid Enforcing" up the top.
At this time I am unable to turn my phone off, when I do it just turns back on and goes to the same screen. I can't get into download or recovery mode either.
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Also thought I should add, my phone doesn't get registered when I connect it to my PC either, it wont show up in ODIN so I am unable to flash a stock recovery at this time.

It's trying to boot into recovery.
When you say you rooted with CF Auto Root, what did you do precisely? And did you follow Chainfire's specific instructions regarding the lack of screen output during the process?

Thanks for the reply.
I used CF-Auto-Root-zerolte-zeroltexx-smg925f.tar to root.
The steps I used was to simply put my phone into download mode and use ODIN to flash the file mentioned above. That is as far as I got unfortunately. I did this once before, a few month back when I first got the phone with no issues. I remember having to install TWRP but I couldn't remember if I did that pre-root or post-root. But I think that is where I went wrong.
Now I am unable to do anything with my phone. I can't turn it off, get into download or recovery mode. When I hold down VOL UP+POWER+HOME it just resets the phone back to the samsung logo screen.
Any ideas on what I could do?

You used the CF Auto Root file for an S6 Edge.

OH GOD. You're right. I just realized that. I was supposed to have them saved into their own folders but I guess I saved that one too the wrong folder.
So what does that mean for the life of my phone then? Is it toast or is it recoverable somehow?

What is your model? Is it the SM-G935F? If so, first things first, download the correct CF Auto Root file for your device (here) and try again. Press VOL DOWN+POWER+HOME and it should reboot into Download Mode. Then try to flash the correct file in Odin again.
These phones are very difficult to hard brick, especially with something like CF Auto Root so you should be ok.

Yes, it is a SM-G935F. Unfortunately I am unable to reboot the phone into Download Mode. When pressing VOL DOWN+POWER+HOME it just takes me straight back to the Samsung logo where it says "Recovery Is Not Seandroid Enforcing". I'm hoping that once the battery drains completely I will be able to boot into Download Mode again.

Try simply resetting it instead. Press volume down and the power key (don't press home) for around 7-10 seconds. Once it starts to reset, remove your fingers from the buttons very briefly then press volume down, home and power to enter download mode.

That hasn't worked either unfortunately.

I just found this thread from a guy having a similar problem. He just had to wait for his phone's battery to drain completely and then he was able to enter download mode again.

You shouldn't have to though. If you can get the phone to reset at all (even if it's to make another attempt to go into recovery) then providing you time it right, you should be able to get into download mode. Did keeping your fingers on just the volume down and power buttons do anything? Keep them on continuously for up to 20 seconds and see what happens. Did you say pressing vol up & home & power made it reset and try to again get into recovery? What happens if, as soon as the screen indicated it's resetting, you remove your fingers and quickly press vol down & home & power instead?
Anyway, even if you have to wait until the phone dies, getting into download will be possible eventually. Then worst case scenario would be you having to reflash stock back. Or, as would be my preference, flash TWRP then flash a custom rom zip like Superman.
Just to confirm, I take it you selected OEM Unlock in dev options?

I have never had any trouble getting into recovery or download before so I know the method. But just the properly clarify for you I will explain some of the combination I have tried without success. Bare in mind the phone is constantly turned on and idles on the Samsung logo.
I have tried:
Hold VOL DOWN+POWER+HOME, the phone resets and goes back to the logo.
Hold VOL DOWN+POWER, same as above.
Hold VOL UP+POWER+HOME, nothing happens at all.
Hold VOL UP+POWER, same as above.
Hold VOL DOWN+POWER+HOME, release and repress all on black screen, just goes back to logo.
Hold VOL DOWN+POWER, release and hold VOL DOWN+POWER+HOME on black screen, just goes back to logo.
and numerous other things like random combination to try and enter Download or Recovery mode, which have all failed.
Right now it's just stuck on the Samsung logo and staying there, taking forever to drain battery. I work in the morning so hopefully it is dead by then and I can get into Download mode.
Have already started download stock firmware in hopes that I will be able to flash it after.
Thanks a bunch for your help. If you think of anything else I might be able to try let me know!

Oh wow. 100+ attempts and I followed your last post about holding for up to 20 seconds. I was waiting ~5 seconds and releasing thinking that it hadn't worked.
Finally go into Download mode and will flash stock firmware and let you know how I go.
Thanks again! I owe you a cold one.
EDIT: Was no need to flash stock firmware. Just flashed the proper version of CF Auto Root and it worked. Again, thank you so much!

Fantastic. Hope you get it sorted.
On a side note, you have probably already tripped knox and you will have lost you OS data and possibly even what you have stored on internal storage. If so, I suggest you install TWRP, format data (you will lose everything with this but it removed encryption) and install a custom rom like Superman 1.9 from your external SD. It's better than plain stock and comes pre-rooted with plenty of other mods.

I can't get it to work? What keys did you held down?
This is how my screen looks

I tried to root with Odin but I think I might have failed. How can I undo this?

recovery is not seandroid enforcing
hello,
my S7 Edge was rooted with cf-auto-root and worked fine but after 2 monthe I've installed LBE_Security_Rel_6.1.1928_A1_DE_v5_signed and reconized the message device is not tooted.
I was not very clever and cofirmed the question "fix the root problem" I don't remember exactly the words. After that root was gone.
I've flashed the stock Fw G935FXXU1APD1_G935FDRE1APC3_DRE but I still have the message "recovery is not seandroid enforcing" after trying to root with CF auto root.
AP:G935FXXU1APD1
CP:G935FXXU1APD1
CSC:G935FDRE1APC3
Is there any way to get root again
Any help on how to fix would by greatly appreciated.
Thanks in advance.

Simply hold down Home + Power + Volume Down for 10-15 seconds - don't release when the phone initially reboots and gives the same error, keep them held down and download mode will appear. I have to hold for 11 seconds, a strangely unrounded number.

Hello Guys I have this Same issue Yesterday....... This happens when you flash outdated CF Autoroot. CF Autoroot Updated on 25/08/2016... Download it...
Fix for Stuck in Logo Screen
Just Click and Hold ...... Vol Down + Menu + Power Keys ...... DO NOT RELEASE. IT Will Restart. DONT release. It will restart again and you will be download mode.

i found this during the rooting process. its a bit different to older samsungs on the s7 / s7edge. YOU HAVE TO KEEP HOLD OF VOL DOWN + HOME + POWER until it enters download mode, which can be 20-25 seconds

928f in boot loop, used smart switch but still boot loop

If the phone is in bootloop she's not dead.
Try wiping it trough the fast boot menu and start over.

Ok, i searched and donwloaded platform tools to get ADB and fastboot, but from what i read i need to be in recovery for adb to pick up my phone, and i cant seem to get into recovery mode, pushing vol up + home + power does nothing, holding power to turn off phone also does not work, as soon as i connect phone to charger it turns on and goes into boot loop, only thing i can do is enter download mode, but in download mode i cant seem to get adb to find phone.

Put it in download mode, push an original OS from Samsung on it and after that you should be good 2 go.

So you already did this;
Phone in recovery mode; wipe it completely and restore to factory settings.
Phone in download mode; original OS via Odin.
After those steps it should work. Had to do the same to my phone last night. Lol.

the only part i didnt do is
Phone in recovery mode; wipe it completely and restore to factory settings.
because i cannot enter recovery, it supposed to be vol up+ home + power, but i think it requires phone to be off, and i cant turn phone off, holding power to turn it off does nothing, already let batery die, but as soon as i plug the cord it turns itself on, and goes back into boot loop, so again when i try the combo to go to recovery it does nothing (because i think it really needs to be off to enter recovery) so all i can do is do vol down + home + power and go to download mode, but i'm not getting adb to recognize phone in download mode, so i could command it to reboot to recovery =(

If you hold all buttons down it will restart the phone. And as soon as the screen goes black release all but volume up and power you should get into recovery mode

I'm having similar issues with my Galaxy S9+. When you say "Wipe it completely" I should do the standard wiping or advanced wiping and select all folders?
