Hi.
I want to mount my old V30 H930 in car, as multimedia station and satnav receiver. So I need to boot him up when charge. I have LG V30 H930, fully unlocked & rooted, with Resurrection Remix OS 8.6.4. When I plugged to charger showed only battery indicator and charging... I tried to put him in fastboot and sent the command: oem off-mode-charge 0 - not result ( FAILED. Remote: unknown command).
Is there any solution for turn on automatic boot when charging? I prefer for any changing for another rom etc, because this RROS working very well for me.
Thanks in advance!
don't power down. problem solved.
Yeah, excellent idea but I want to built-in the whole smartphone with no access to back and power switch... Sometimes phone will discharged to zero when I'm not using the car... I noticed that he is booting when using Qi charger... Only Qi...
Aby other ideas?

Hi. So I have an Lg Optimus G e970 from Att. Its runing stock 4.1.2, rooted (using CurrentRoot.bat) and has an unlocked bootloader (using freegee from the app store), the problem is that when the device is turned off it will not charge, I get the charging screen (where the bettery appears) for a few seconds, then just a blank screen. So it does not charge, and the screen remains on. Any ideas?
when the device is turned on I have no charging problems at all.
I had the same problem..i wont charge when switched off..Now using rootbox and everything working fine.
If memory doesnt fail me, all rooted devices do this. While theyre off the battery logo will appear for a while go out and then the backlight will stay on. if you touch the unlock button the battery will appear again. Are you using wall charger or travel charger? Are they original devices?, could be a voltage problem

Wall charger, original devices.
Yep, I'm having another round of issues on my One.
Just some information:
Running stock ROM, bootloader locked (not "relocked"), S/N HT346(...), Quick boot OFF, previously sent in for repair.
I believe this has been brought up before, but here I go:
I pulled the phone off the charger this morning with a full charge. However, Car mode unexpectedly opened up. I found this odd, since I'm running a stock AT&T ROM using the Sense launcher, which means Car mode is nowhere to be found. The device also reported using an "incorrect charger" or some other thing. I use the charger that came in the box with my phone. I assumed it was a mistake.
However, in my infinite wisdom, I decided to brush it off and went on with my day.
Usage patterns normal, maybe with a bit more GPS and camera use than usual, but more or less a normal day.
Come back home, plug it in. Phone will not charge. I do not believe it's a hardware issue. Why?
Troubleshooting time:
Plugged into another outlet, will not charge.
Switched wall warts. Will not charge (I have a few from older HTC phones and a few from other Android devices).
Switched USB cables. Will not charge (tried combo-ing with wall warts, same result).
Plugged into PC. Will not charge AND does not recognize USB connection (both ends). Tried with several different cables, no dice.
Rebooted, no dice. Did it again (and several times after that), no cigar.
Safe mode: Nope.
What works?
Connect via fastboot works (so "FASTBOOT USB" works)
It WILL charge when powered off.
Now, as the title states, I noticed the LED blinking when the phone is powered off and plugged in via AC or USB.
The orange LED will light up for ~6 seconds, dim down (to the level of brightness that would be considered "normal" for the phone) for ~6 seconds, then turn off. The process repeats after the LED turns off for about 5 seconds.
Any ideas on why this could have happened (including my own stupidity) and what I can do to solve this problem? I'm going to send it in to HTC if nothing gets it working again (and has it stay that way).

Hi,
long story short: I connected my Z5C to a bad (apparently, I don't want to test ) charger and now I have some strange issues. Is there any change that my h/w isn't fried?
Full story: As I said I connected my Z5C (newest CyanogenMod provided here) to a charger and it instantly did a hard reset. Afterwards it did turn on and continued to work for some time. As I was on the road at that time I could not charge it elsewhere and later that day it ran out of power. When I tried to charge it with a known good charger some days later, it did not boot. I suspect the boot process to healthd or whatever draws this cool animation takes more power than my working but small charger provided.
It did charge at my laptop, especially when I put it into fastboot mode.
Now thats where I am stuck; the phone won't turn off completely and keeps rebooting when I turn it off (via os menu or hard reset, no chance).
I can charge it after it runs out of power (managed to charge to 100%), but it won't charge if I unplug and replug it. It is not recognised by a pc after I reconnect it one or two times (checked with device manager and lsusb), only chance to get to fastboot or flash mode again is drain the battery to 0%. It does show a loading animation and I can boot into android from there. Battery drain in Android seems to be a little higher than usual (100 to 0 after 2 1/2 days of pure standby without any radio stuff on).
I have already reflashed the original Sony firmware and erased everything that came to my mind (cache, data....).
Any hope that I did not kill some piece of hardware?
Thanks for your answers, any help appreciated
tell me more about your z5c's software, why you mentioned Cynogenmod? did you flash it with cynogenmod?
seems to me that z5c was running on custom rom and did not support fast chargers and bricked your device!
if that so, try flashing it using flashtool with original stockrom.
i don't wana go in to details however there is possiblity that battery.sys file is corrupt and atleast I was never able to fix my LT18i when it got bricked and battery status use to become zero in 2 seconds and android keep rebooting, later it got silent for good! no charge no nothing and i still have the device sitting. I was running it on coconut (cynogenmod) when all this happened!
Thanks for your reply.
The charger was no kind fast charger, just a common 12V to USB adapter with an output of 800mA (when it worked). I was running CM 13 when I connected it to the bad charger, but as I mentioned I have since then reflashed it with Stock ROM. No real improvement.
I have continued trying and I found out that the device seems to believe it is still connected via usb.
Code:
cat /sys/class/power_supply/usb/present
gives me "1" with nothing connected, can you check if this is normal?
The file is -rw-r-- r--, would changing its value change anything or is it just some kernel thing (can't check, don't have root permissions now as I flashed Stock ROM)?
Also after I charged it on my PC today it still shows me the notifications for USB connection and adb (I can add a screenshot if necessary), also looks like it still believes to be connected.
It seems I found the solution: I was playing a bit with a USB-OTG adapter (the ones to connect regular usb devices like keyboards or storage to your phone). After I connected a USB keyboard I tried (just for fun) if the Linux "Magic" SysRq hotkeys were enabled. So I did press Alt-Print-o, which is the Linux hotkey for "turn off now". It did not turn off, it also stayed off (no instant reboot). After I started the phone again it also properly turned off via the power menu!
I will have to test whether the charging issues are fixed, too, but as far as I can tell the problem seemed to be something software-related
Sadly did not work for long. I think I will go for official repair, think this is still cheaper than buying a new phone (after completely killing it with some DIY "repair" attempt). This annoying brick simply does not turn off, no matter what I do (apart from draining battery to 0%). Guess its my fault, still to afraid to try that broken charger again.
My phone rn3 pro 3gb varient only turns on while charging(shows mi logo for 2 sec then turns off while unplugged), as soon as i unplug from charger it turns off. fastboot works even when unplugged, but for booting to recovery needs to be plugged. Already flashed stock rom via mi flashtool but didn't help

This happens because of a bad battery. It may charge OK but its increased internal resistance will stop the boot process which at peak demands over 1A power supply. If you connect it to a good 2A charger with a short quality USB cable and turn it on, it may actually properly boot Android. So, it's time to replace the battery.

but fastboot boots up without any problem. On fastboot the device doesn't switch off itself.

I'll quote myself from this post https://forum.xda-developers.com/redmi-note-3/help/phone-mi-logo-1-off-help-t3766929/post75976361
"It can not handle the high boot up current required for Android stage but is good enough to run fastboot. Sometimes it may boot Android if (2 Amp) charger is connected while turning it on."
"Damn man! You're the man! It's been lying unused since a freaking year!
I tried with my S7 Edge charger and it turned on. Turns off if I unplug it.
Can't believe the SC told me to replace the mobo.
Shall I get a battery off eBay? Is it easy to replace the battery by myself? "

I replaced battery, now it's working perfectly fine
Same problem with me
Today I have replaced the battery
now its working as usual
Hi!
Last night my phone started acting up when I connected the USB cable to charge it (connected to PC).. it kept saying the phone is charging slowly so I had to take the cable out and reinsert it multiple times to get it to charge properly.. today when I was charging using my powerbank the screen turned off and when I tried to use the phone it was unresponsive so I restarted using vol - and power. Now when I restart the phone it turns off and only boots if I press vol - and power for 10 secs.. also when I turn it off I cannot turn it back on by pressing only the power button and I have to press vol - and power together to boot.
In the Developer Mode Options.. USB Configuration screen is completely blank.. All I see it "Only Once" and "Always" options with nothing above them.
I cleared cache and that seemed to fix it for several hours (maybe a fluke) but now even that is not working. I upgraded to Pie using LGUP a month ago and did not experience any problems since this. Now the phone is not detecting ANY connections in the USB port (PC connection or wall-charger) meaning I cannot charge it. I do not have a wireless charger on hand to test wireless charging. I tried soft resetting it using the Factory Reset option inside the OS. Made no difference. Cleaned the lint out of the port using a thin plastic straw.. still the same.
Has anyone else ever experienced this? Is the charging port bad? or will somehow charging it using wireless charger (if that works) and then going back to Oreo fix it? Can hard reset work? I had less than 30% charge remaining so I turned the phone off.. will turn it back on in the morning to see if that made any difference.
Help.. :crying:
Update: Hard reset did not fix it.
Update2: Phone charges for a while when I reboot it by pressing the vol - and power from within the OS.. charging normally now and also letting me choose USB configuration mode... will see in the morning if its charged and responsive..

Yes, Qi wireless charging can charge if USB port is messed up.
Yes, hard Reset can fix stuff also.
Rather than PC and powerbanks, I would stay with regular plug wall charger, preferably with QuickCharge 3.0.

I don't think its a HW issue.. seems to be a Pie issue.. I had the AME Oreo on this phone and LG did not release the Pie for the region so I installed the HK Pie on this.. maybe that is the problem and I need to refurb the SW using LGUP again or downgrade to Oreo

I'm in a job where I am mobile most of the time and do not have access to wall chargers.. Have my laptop and powerbank with me at all times though.. Thanks for your help.. :good:
I agree on it being a Pie issue. My V30 is having ISB Configuration problems too - can ONLY detect it to charge, 0 other communication with 3 computers using 4 different cables.
The vol down + power trick doesn't make mine work at all either. Currently I am stuck with a fairly useless Verizon phone because I can't use the damn USB connection on it.

I'm still on rooted stock Oreo firmware because I don't see anything better about LG's Pie. The last Oreo is the most stable.

I wouldn't be on Pie if the phone wasn't already on it when given to me. Seems like it broke USB Configuration on a lot of phone models, but the V30 still hasn't been issued a fix and nobody can explain why not all V30 were affected. Verizon basically told me to go **** myself because I am not a Verizon customer, lol
Fixed it once by reflashing the software using LGUP and now its back again... backing up now to reflash... this is a pain in the backside.. took just 3 months for the USB to start acting up again.. I got the moisture or debris in USB port message this morning.. so cleaned out the USB port and now acting up just like in my OP...
