Lg boot loop no recovery - LG V20 Questions & Answers

Hi I have a sprint lg v20. Shows lg boot screen and loops. I try to get into recovery mode to factory reset but says recovery mode please wait then continues looping the lg logo. I have not found anything saying they had a similar problem. As far as I know there is no fastboot mode I can use. Any ideas on how I could fix it? Thanks

Did it just start out of the blue, or did you do something?

Can you get in to download mode? (vol+ then plug in to PC) If so, you may be able to use LGUP to flash a kdz.
Good luck! :fingers-crossed:

LG G2 (LS980) Bootloop and no Recovery Mode!

While attempting to put Clockwork Mod Recovery on my Sprint LG G2, my phone restarted and was stuck in a bootloop. I attempted to boot it into Recovery Mode to wipe data and hopefully fix it, but when I held down the volume down and power button, a screen would flash saying: "Recovery Mode. Loading..." and immediately take me to Fastboot.
Does anyone have any idea on how to fix this?

[Q] LG D800 Download Mode Detection Problem

I have Lg G2 D800. It is stuck in bootloop. It hangs on LG logo screen with a blinking notification lite. It can go into Download Mode but PC did not detect it there. Whereas on hanging logo screen it is detected perfectly well. can be seen in Device manager but not in Download Mode. So i cannot flash stock firmware. There is no stock or custom recovery mode as well so that i could use sideload method. One thing i know is that its boot.img, laf.img problem. If i could go into fastboot mode again i can solve this problem. But do not know how can i corrupt boot partition. Please help me in any way to get out of this situation. Thanks

[Q] LG G2 loops LG logo, semi goes into download mode?

Hi
I was trying to restore my LG G2 D801 T-mobile to stock firmware but the phone would not enter into download mode. It would say something like boot certification error and then to a black screen. I followed this guy's tutorial on properly entering download mode but it then cause the LG logo loop http://forum.xda-developers.com/lg-g2/general/unbrick-lg-g2-qhsusbbulkqualcomm-9006-t2939627
When it is stuck on the LG logo it shows up in my device manager as 'LGE Mobile USB serial port', however when I go into download mode, it's stuck on
Fastboot mode started
udc_start()
-- reset --
-- portchange --
-- reset --
-- portchange --
and my computer recognizes the phone in device manager as 'Android'.
How can I fix this? Is it possible to even be fixed?
Thank you and apologies if this question has already been answered before.
Am I screwed here? I can't get into recovery mode or download mode. When I try to get into recovery mode, it says 'would you like to factory reset your phone'. I go about the process, it shows the android logo then back to the LG logo forever.

Lg v20 stuck on bootloop

Dear xda Developer,
I have a LG v20 H990DS international Model use in KSA. Every think is working good after I factory reset then it’s started the boot loop, shows Lg boot screen and restart again and again.
I try to enter into Download mode (Vol+then plug in to pc) but say Download mode please wait then continuous looping the lg logo. The only mode that I can get to is fast boot. Even doing a factory reset does not work.
I know only Fastboot mode is last hope for my phone alive.
I know the method of partition but problem is when I erase laf.img through fastboot mode its say device is lock cannot erase.
I check LG unlock bootloader page my device is not in listed.
Please any one provide unlock bootloader file .
If you didn't root your phone, your phone has a hardware problem. You have to send it to LG.

I'm sorry for your loss. To me it sounds like something may be physically damaged.
To elaborate a bit further, fastboot doesn't usefully exist without root, stock recovery can only wipe your userdata, and you've already said download mode reboots way too early to try anything. There is no safe way to try anything with the firmware, if it even somehow is a firmware issue. There's the leaked firehose, if you force it into 9008 mode, but that's risky and I have no personal experience with it to give more details.
Basically don't expect it to be coming back.

Without it already being rooted and the dirtysanta bootloader installed there is no fastboot mode on anything (which you would have seen if you had read the OP) but the h918 (which still can't flash with it) and us996, and you still need a working phone to actually set the options in Android to allow unlocking the bootloader.
And I'd put it at like an 80% chance it's hardware failure anyway, since it's boot looping in download mode too.
Try holding down volume down and plugging in USB.......
Same issue herewith...
LG V20 boot loop , restarting again and again , also when USB cable method is applied to enter into the Download Mode , it also restarts after sometime after showing download mode icon etc........
