Hey guys. I tried rooting my LG G4c but after rebootingen it seems that my phone is stuck in a loop, and i can't fix it.
What happens when i turn the phone on:
1. LG logo turn up
2. The following message appears:
[670] --------------------------------------
[670]
[670] Boot verification fail!!
[670] - cause : MISMATCH_SIG_LEN
[670]
[670] --------------------------------------
3. Phone reboots
Using the power button + volume down does NOT work anymore to start recovery mode (although starting the IMEI display still works).
I tried using LG UP to install the original firmware via USB but the device does not show up in the list (probably because the phone keeps rebooting itself). Some website also said to connect the phone with the pc, turn LG UP on, then put out the battery and put it back in to make it work, but that also didn't work.
Anyone know what i can try next? What method can i use to reinstall the firmware? And if it's not possible, does it cost much to repair and who should i ask?
Edit: It seems i can start "Factory data reset" but when this proces starts the phone restarts and continues the loop with the error message.
I also tried connecting the device with LG UP while the phone is stalled on the IMEI screen and the Factory data reset screen. This way the phone does note restart itself and it might appear in the device list of LG UP. But too bad it still didn't work.
I don't know if i'm reaching anyone who can help me, but even a answer from anyone saying that the problem is hard to deal with would already be very relieving I really can't find anything related to this problem on the internet and i'm noobish myself. I'm probably gonna visit a some phone shop down town in the next days because i really don't know what to do.

I had this problem too. I send it to LG and said the phone was unplugged during update process. They flashed it and I gave it to my mom. I have an S4 yet. Much better performance and rom support.
download mode

Can you get it into download mode?
So i was rooting my phone with TMWP then my phone was encrypted so i used Odin with an original AP of my samsung device
in the progress of doing that i canceled the progress.

Use the Emergency recovery function in the Smart Switch Pc software. so i did that but now i am at this step, telling me to put the phone in recovery mode but when i try to do that it keeps giving me the same error (An error has occurred while updating the device software. Use the Emergency recovery function in the Smart Switch Pc software.)
Im freaking out right now if you guys could help PLEASE.

Probably the phone is not detected?
Sent from my SM-G925F
How are you getting to recovery mode?
Should be Vol Down + Home + Power all at the same time
Are you able to power off your device?
If not, press and hold Power + Vol Down until it vibrates or you see it turn completely off, then hold Home (while still holding Power and Vol Down).
Give that a shot to get to recovery.
I had this problem when i tried messing around with TMWP. I dont belive there is one for the S7 egde US models to my knowledge or at least not for att currently due to the us and international models having a different processors International having a Exynos 8890 and US models having a Snapdragon 820. Im pretty sure because of those having different processors TMWP needs to have a build for both processors to my knowledge fix me if im wrong.
Heres what i posted on another thread about trying to flash your phone back to stock and it not working.
Post:
So I would suggest going to this post here and downloading the ODIN 3.12
http://forum.xda-developers.com/showthread.php?t=2711451
I was trying to unroot for a clean root and this one worked for me the one made by PrinceComsy did not work for the flashing the stock ROM but it did work for flashing the ENG Boot ROM. I used 3 out of the 4 file to flash the stock rom I didn't select the BL file at all but you can if you want.
If this help you or you need further/help assistance please feel free to reply to this post

I had the same problem. It is a screen that says something along the lines of 'Update failed' or 'an error occurred during update'. It turned out for me that that actually was recovery mode just with the error screen. Plugging it into Kies on that screen allowed the emergency firmware to work and fix my phone.

If you can find the firmware you can fish from that screen. Boot download and when error pops up you can see it connect in Odin. The issue is finding that firmware

Thank you, very good to know, i need this firmware now
Phone still broken. Attempted to flash active-G892AUCU4BSC1 firmware just to have it running and odin 3.13.1 fails everytime. It gets to the end and just fails. Still don't have answers
The BSC1 firmware is linked 4PDA, in both AT&T and unlocked form.
Hey there, I never backed up my tab A through smart switch. I ran into a problem with a software upgrade and now it won't let me reboot into download mode, recovery or even shut the stupid thing off.
It tells me to connect with smart switch and reads as I quote
"An error has occured while updating the device software. Use emergency recovery function in the smart switch PC software"
Well there's no device that shows up
I've reinstalled the drivers and the software.
I am at my whit's end here
As I stated, I can't even get the darn thing to shut off it just continually reboots to give me this same crap.
Any help would be appreciated, I am on stock rom
So while looking around the house I found my old phone, the Samsung Galaxy J5 and I tried to turn it back on. It looped on the logo screen and that's when I remember that I bricked it when I was playing around with rooting device all those years back. As someone who never tried to play around with my phone data ever since then, I decided to just check a lot of thread relating to the topic and conclude that all I need to do is to flash the device with a newer version of the android OS(?)
I get to work and download Odin and manage to find some of the data needed. All is fine until when the bar was about 90%, it says
"Custom Binary(system) Blocked by FRP lock"
After a lot of reading, I found out that it's a safety system so people can't just steal and reset the phone to be sold again. Understanding that, I kinda gave up on the whole "fixing" this phone thing and just decide to reset the whole thing since the stuff inside the phone shouldn't even be that valuable; perhaps a lot of photos and memories but nothing other than that.
Now my smart ass decide to just unplug it from the PC and just turning the phone off by taking the battery off. Turning it back on now shows a new page
"An error has occurred while updating the device software. Use the emergency recovery function in the smart switch PC software"
I tried to flash the OS from Odin again, it stopped at the same exact 90% line with the same "Blocked by FRP lock" on the top left corner. I tried downloading smart switch, there's nothing on the emergency recovery function page other than "403 Forbidden". I tried to download an older version of it and tried to just use the device initialization and it says that it isn't supported for some reason.
At this point I'm lost and stuck with a bricked phone asking me to use the emergency recovery function. I cannot even go to download mode or the "Home+power+volume up" mode anymore.
At first I want to save the data but now as long as I can reset it I'm just happy. Can anyone give me a guide on how to fix this? I feel like I manage to pile problems on top of problems and now this phone is basically hard bricked.
My phone is Samsung Galaxy J5 (SM-J500G/DS). All help is appreciated!
