Hey guys,
I have an LG V20 vs995, that's rooted using the dirtySanta method. All was running well until I went to swap batteries. On power up I see LG, then it goes to multiple bars of static with what appears to be a circle in the middle. However if I plug in power then unplug it, I see the LG screen followed by the Safety check warning; then it boots up normally. I'm running TWRP with Magisk
Here are some things I tried.
reflash twrp
reflash kernel update
I feel like my only other option is to reset phone, but before I go there, I just wanted to see if anyone had any other ideas.
Thank you!

Hey guy's,
I found the fix for my issue, and just wanted to share. The screen that I was stuck at was the firmware update, but because I'm rooted I get static on this screen which in turn makes it hard to read. The other night I was stuck in rain. My charge port must have gotten a little wet, and this will make the phone think that a data connection is plugged in ready to update firmware. The quick fix is to dip the tip of the usb cable into rubbing alcohol, then insert into my phone charge port a few times. This cleand up my change port, and now my phone boots perfectly.
Had I known from the beginning, what screen I was stuck on this would have saved me a lot of troubleshooting.

Ok, so I have a Bell atrix and followed the instructions on this thread to install GreyBlur:
http://forum.xda-developers.com/showthread.php?t=1070076
I have not done deodex on the phone.
My phone ran out of battery and shut down, so I plugged it into the wall with the moto charger and the red logo came on, but then froze. Usually the battery charge status would come on (before i installed GreyBlur). But now it just gets stuck on the red M logo. If i unplug the phone, remove battery, install back in and turn on the phone without the cable, the phone turns on fine and i can charge it with the wall charger after the phone is booted. But not when the phone is turned off.
anyone knows why?
protip 1# change thread title to relate to the problem you face instead of 'OMGZ LOLZOR HELP MEEEE!!!!' you will get more responses
now for your help
a few things: do you have Tenfers CWM installed? im assuming you do as you are trying to do Greyblur
sounds like to me the phone is bootlooping. my solution would be to start clean with a frsh SBF install as this will be the quickest solution
I changed the title, thanks for the tip
Yes i do have CWM installed.
I have already installed greyblur with no problem as i followed the instructions that were provided in the link above.
There is nothing wrong with the phone as long as it is not plugged in to the charger. It boots just fine and loads greyblur. But as soon as I shut the phone down and plug the charger, it gets stuck on the M logo.
I am kind of a noob and would appreciate it if you tell me what you mean by 'installing a fresh SBF'
thank you
Hey there,
you may want to make sure that you set the system recovery app back to charge mode as this may be causing your error.
^^^ thank you so much. I tried what you said and it worked
glad to help
So basically this rom is awesome but it had only one problem. When I plugged my phone in the charger while it was turned off, it bootlooped until I restarted with the cable off. It was no big deal and nothing bad ever came out of it.
Yesterday my batter ran out while I was asleep and when I woke up it was already turned off. I, absentmindly, tried to turn it on, LG Logo, off again. Did it one more time, nothing happened, realized it's out of battery. Plugged in charger, try to turn it off/on, usual bootloop happens. Say ok and proceed with what I always did, phone gets past LG Logo, goes into SlimLP boot animation and for the first it has just stayed there. No restarts, just endless loading. Longest i Left it on to load was about 45 minutes. Never got back on.
Apart from that, I think that for some reason my recovery got uninstalled somehow, by itself, a few weeks ago. I only noticed this because before, when I wanted to get into recovery, I pressed the usual buttons and it went straight into TWRP. Now the same buttons take me to the "Factory reset screen". I know that everyone says to just go ahead and press power, but I am afraid, since I am not sure if TWRP is still functioning. This happened to me another time on the same phone, and when I confirmed the factory reset, it factory resetted.
My problem here is that I want to get my music and photos. I'm only able to enter that factory reset screen and download mode. Can I "flash" twrp safely from download mode? Should I use Flash Tool 2014 and Normal flash(which says it keeps the data) a stock g2 rom? Can I mount my phone to the computer in download mode to copy my files? I want the most risk-free approach.
Thanks in advance.

Hi, first If you can enter download mode I think you can flash kdz (Kitkat) file to stock using Flash Tool 2014. But I had this problem once and the keep data flashing didn't work (stucked at 50%), I ended up flashed it with other option (erased all data).
2. You can try the "Factory reset" nice and easy.
I think you can't see files on the device unless you enter Twrp.
It's wise to backup your phone on the computer montly or so, thank you.
I went ahead and nuked my download mode using the SRK tools. Then got access to fastboot, through which I booted to twrp and then I could move my files. All's fine, flashed my ROM again and it's going better than ever.
Okay, so heres my issue. Moto Z got wet. It happened during an accident at work and I got a bit side tracked and after a while I noticed the phone was getting really hot so I accidentally restarted it instead of turning it off. Now the phone is stuck in a boot loop. I can get to the boot loader screen. I can restart boot loader via button commands but anything else I try for instance, recovery mode, it goes in to the loop again. My laptop ( windows ) see the phone but not a as a Moto z and I can talk to it with commands on the laptop. I"ve tried flashing with no success. Maybe I'm not doing something right on that part. I'm not trying to unlock the bootloader mainly because I can't considering the model of it. I just want to restore the firmware on the phone. Is it possible? Many thanks in advance.
Yeah I own this cell phone as well. Some trick you could try is to let it drain power wise out. Get a zip-lock page for freezer add a folded paper towel with it and your phone. Leave it in the freezer for 30 hrs. Plug it up to power turn i on. Note if you have changed anything to the firmware to the cell phone this might not work.
Thanks for tip tipstir. I have been trying to restore the firmware for a few days now, researching like hell. I didn't touch the phone for about a week before attempting to restore it. Yesterday I used an all in one tool form a developer here and managed to stop the boot loop. Now all it does is boot to the fast boot screen. It still won't go in to recovery or anything. Flashing fails on RSDlite 3 out of 38 steps. Anything else I can try?
Please help! My S5 Neo was in a drawer for a few months after the LCD got smashed. I recently bought a new LCD assembly and connected it to make sure it worked before fitting and it was fine. However, the phone immediately started doing a software update but was interrupted after a few seconds as the battery was dead. Now the phone won't power up or boot into download mode or recovery. When I plug the phone in to its charger, the LED flashes red but nothing is displayed on the screen. I had a new battery for it and charged it in another device but still no joy. I've been messing around with old galaxy phones for a couple of years now, flashing custom ROM's etc, so I wanted to just re-flash a stock ROM into it but there's no way I know of performing this without getting the device into recovery or download mode. Does anyone have any ideas? The device is totally stock and hadn't even been rooted. I'm currently using an S4 Active running Lineage OS 17.1 so I'm not desperate for a phone, but I loved my S5 and really would like to get it up and running again. It never once had any problems.
TL;DR it's bootlooping, and I can't enter download mode.
My V20 H910 hasn't been touched for a couple years now. It started bootlooping years ago, and it's only now that I'm trying so hard to fix it. When I try to boot it, I get the LG screen for a few seconds, then it goes all black, and then it repeats until I pull the battery.
I can navigate to the screen to initiate a factory reset, but when I confirm, it freezes up for a moment and then goes back to the boot loop.
When I plug it in to initiate download mode, I get the screen that says it's trying to start download mode for a couple seconds, and then it goes back to the boot loop. I tried launching LGUP during this two second period, and unsurprisingly, it does not see the phone.
I've tried putting it in the freezer, and I've tried using a different battery. I tried "discharging the capacitors on the motherboard" by removing the battery and pressing the power button fifteen times. This causes it to vibrate briefly when I attempt to power it on, but then it bootloops as normal.
It's totally stock Oreo - no root, no custom ROMs, no TWRP, no unlocked bootloader. I might have enabled USB debugging, but that doesn't do me much good when it won't boot (yes, I tried ADB anyways, and no, it doesn't see it).
I did use third party USB cables to charge it back when it worked, so I am aware that this may just be a faulty motherboard. But I'm hoping there's another option I haven't pursued yet.
What do you think? Is it a brick? I've spent all day searching for potential fixes, so any help is appreciated!
