Hi mates. I have a weird problem. Just last night I am restoring a Nandroid Backup of VANIR ROM for geehrc, which DONT have a problem with my phone. When suddenly after booting and showing the lockscreen, the phone becomes unresponsive and after a few seconds, turns off. After that, It wont boot, even fastboot or recovery wont show up. Even tried the hard reset combo, but to no avail. Download mode works, but I have not tried to flash KDZ yet. Also when I plug in the charger, LG logo shows up then a blank grayish screen, then a battery icon with charging animation, plus a label that says 0% charging. I leave it for about 4 hours, thinking that the phone might just depleted the battery. But still it wont turn on. When I turn it on while plugged in, the LED blinks in red color. The blinking is continuous. What seems to be the problem? Is it hardware or software issue? Please help me guys! :crying:
Any help mates?
Im really loosing my hope reviving my device. Tried different methods from the web. I just flashed KDZ, but the phone keeps flashing the LG logo when plugged in. When I unplug the charger, and power on the phone, nothing happens! Damn. Can anyone give an insight on what might cause the problem? Thanks in advance!
Sorry to hear about your troubles! Honestly, I have no idea what could have caused this, but if I had the same issue, and nothing worked as you described, I would probably crack the phone open, disconnect the battery and just let it sit for a day or so. Then reconnect it, and try powering up again (might need to charge it first). Who knows whether it helps or not, but it definitely wouldn't hurt, and you don't seem to have a lot of options right now...
It's interesting that the download mode still works. The common wisdom says that you should be good after flashing stock KDZ, but your experience shows otherwise...
i've experienced it before. It happen due to your battery is out of charge. What i do is, i open the case, pullout battery and install back.
After that i charge the phone. And voila...charge is on..and my hp on too. :good:

Thanks for your feedback! It's really weird. I have flashed 3 KDZ's already. From Original F180K to E975. Nothing. Other option I have aside cracking it open is returning it to the seller fro check up. But that's the last resort. I suspect something got "unglued" while I am using it. Since the device got really hot before it happened.

Will definitely try this. Thanks for the advice. How long should I remove the battery?
I just removed for a second and put it back. Most probably due to battery not fit. So i just retighten it.

Should you go ahead with it, and in case you've never opened an OG before, just a little advice... It's not difficult, but you need to watch for a couple of things:
1. Make sure you remove the SIM tray BEFORE removing the back cover.
2. Start opening it from the bottom (after removing two screws), and work your way along the sides to the top. When putting it back together, go in reverse (top to bottom).
3. Be careful around the SIM slot and the buttons when prying the cover open -- it's easy to break a thin "bridge" on the side of the cover. Just don't push on those areas.
4. When putting the cover back on, it might be a bit tricky to hold power and volume buttons in position. The easy trick is to use a piece of scotch tape on the outside, so they don't fall in.
Good luck!

I wouldn't suggest actually removing the battery, unless you absolutely have to. It's mounted by a double-sided adhesive tape, so taking it out is a bit tricky. My idea was just to disconnect it. You need to undo two screws that secure the power connector, right below the camera flash. The screws are under the plastic tape, just peel it off. When you remove those screws, carefully pull the connector up. That's it. Check the contacts for any signs of damage or corrosion, and clean up as needed. When reconnecting it, push firmly to make sure it sits properly.

Nice tip again! Thanks! Now I don't have remove the battery. Only problem left is finding the small philips screw driver. Haha. Hoping that this solve the problem. If not, bye LGOG.
Thanks for all the helm mates! My LGOG is back in action!! Thanks again! :laugh: :good:

ok. worked for me fine! Thanks!
now 80% battery instead of 0% very cool
and now i know how it looks into the phone very good working LG...
No more charge stuck on 0% sulation
when I plug in the charger, LG logo shows up then a blank grayish screen, then a battery icon with charging animation, plus a label that says 0% charging. I leave it for about 4 hours, thinking that the phone might just depleted the battery. But still it wont turn on.
SOLUTIONS:

Hey guys,
I have this weird problem with my HTC Desire 816. When i put the phone for charging its showing the RED LED and the battery Symbol is shown in the screen but it never gets charged. I put the phone over night and still not a single % charge.
So i asked the owner , my cousin who gave me the phone about the problem and then he told me its because of water damage. he gave to the HTC people and they said it can't be fixed.
So now i'm with this good looking brick, not knowing what to do. Can it be fixed ? Has anyone had the same problem ?
When i put the phone for charging, the screen comes ON and shows the empty battery recharge Symbol and then gets OFF again shows battery Symbol, Kinda like Boot loop.
My mind saying i can bring back the phone to life. Can anyone help me some technical ideas which i can try ?
I will upload some pics asap.
Thank you
You can try unplugging the battery and plugging it back in. I think it's impossible to tell if the battery is bad or something else in the phone is bad without removing the battery. You can find replacement batteries on Ebay and other places on the net.
BTW you can find a video on how to open the back in the thread about replacing the digitizer and lcd. Basically you need plastic pry tools and you start @ the sim/sd card slots and go around popping the back off. The bottom half also has sticky tape holding the back.

So i guess its not an easy task. But i wont quit. I just need the right tools for the job.
should i remove LCD plug , Digitizer to take out the battery ? Lets hope unplugging the battery and plugging it back will fix. :fingers-crossed:
Will get back to you, if i got stuck somewhere.
Thank you !!
No, just remove battery. I used cut up credit card strips and whole credit card to help me get back cover off.

Using a CC made it easy opening the Back Cover , Unfortunately there's nothing i could do to bring back the phone to life.
Apparently the board is fried.
So that's it i guess. Goodbye to HTC.
Anyways Thanks man for the help. :highfive:
But Still i wonder, how come the screen works if the board is dead & LED also works?

I think most everything in a phone is modular to cut repair costs. You don't want to have to replace the main board if someone drops the phone and cracks the screen. Maybe you can sell the phone on Ebay "as is" for parts. It seems like the screen and digitizer still work and probably the battery too.
hi everyone,
i having an issue with my battery level and it really pisses me off.
the battery level stuck at 50% - charging or not, it means you will never know if the phone is full charge(on charging) or nearly lowbat(discharging).
Also, it says "battery usage data isnt available.
it stays 50% when in recovery mode too.
i did the ff troubleshooting:
- wipe data, cache, system, etc.
- installed AOSP and CM ROM
- tried downloading battery test and everything is normal -
NOTHING CHANGED
The the battery stays upto 10+ hours but its hard to live without the battery level
hope you guys could help me with this - THANK YOU IN ADVANCE!

Got it fix
hi guys i found a fix here..
i did everything i mentioned above but none of those work so i thought it was a hardware issue and i was right.
this is what i did..
I removed the cover of the battery or battery plate (probably I had to unscrew everything) at the middle of the unit there were 3 flex connectors, and all i did was removed those 3 and carefully cleaned it. i used dry toothbrush then put the flexes back. and turned on the unit- and it workS!!!! then put everything back -
never had issue again with the battery
I am not responsible for anything if you follow what i did. there are some videos on youtube how to remove the battery plate that holds the battery..
thanks

Are you sure about this???, i did and nothings changed..
I had the same problem and i took it to a service centre,,, they told me it was the problem of the motherboard....They changed the motherboard and now its working fine
i lived with this for a month till i found an accidental fix for this. i plugged in earphones (first time) to listen to a meditation app that i'd just downloaded, and when i unplugged the earphones and charged the phone, the charging display went back to normal.
This usually happens when there is a loose connection between the motherboard and the battery. It happens on other androids too.
Same here...
I am facing the same issue.. battery bar stuck at 50%.. Sometime hitting at back restores the function.. but again goes back to same within a day or two.. very irritating..
The problem is not the software. the way you fix it is take off the back plate, remove all the tiny Philips screws and remove the hold down backing plate, and take a piece of paper and fold it 2 or 3 times and place it on the black foam piece that the battery connector is on the top of the battery, that's the battery connector connecting the battery to the phone electronic board. the problem is the connection is loose. what you are doing is creating a shim to push the connector in more. you could use electrical tape but paper works ok and you can control how much pressure to apply. do not use too thick of a piece for the shim or you would bulge out the hold down backing plate.

This actually fixed it, I got the battery of my phone replaced from the service center for another issue and got this problem after they replaced it. Wondering why they don't know about this problem they could have prevented it before it's released. First time I had to do this on my own as I'm frkn tired of going back to them. Thanks @eksine :victory: glad you visit XDA from time to time.
I must say : Asus Zenfone 2 is a peace of sh.. or maybe garbage.
I have problems with this phone from the day one.
Whatsapp,
battery (died after 4 months),
bad signal for internet (my other phones works much better),
software,
now the new battery is stuck on 50%
I promise that I will never again buy any product from Asus in my life, because this phone has destroyed my nerves.

Good find!!
I change a battery by myself and after that I stuck at the 50% too. After I read your post, I reopen the cover and found that the battery connector is really loosen and I apply your shim method to make it more better connection and it can read the actual battery percentage.
Thank you!
Hi
I have a problem with my G3. When i start it, it shows lg logo then few it reboots again without getting anywhere. But if i put the charger it does work flawlessly. If i take off the charger, few seconds and it reboots. Is it a battery issue? Software or hardware?
Thanks
Yes, its battery problem. I think its time for you to change the battery.

Yes, it is a battery a problem, so i bought a 2nd and a 3rd but the same problem happened with the 2nd in less than a month, the 3rd in 2 weeks.
I wasn't ready to buy a 4th one so i looked around and i found a solution and it's working for me so far without a problem.
the solution isn't mine so all credits goes to Marko Peltonen in Android Central forums.
He explained the problem here
And the solution with pictures here
Some remarks to take in consideration:
the wire should be thin (from a strand);
when you're manipulating the wire be careful not to let it touch the body of the battery (if you peeled the plastic off the battery) when it's connected to the + connector.
the soldering point on top of the control board should be as thin as possible so you can put back the plastic cover
hope you can solve this frustrating problem

It could be a software problem. don't go hardware at 1st. What's your configuration (ROM, kernel, Recovery)?

Everything stock. Flashed MM stock firmware a few days ago.
While it was flashing the lg flash tool crashed on my pc at %70 or so. Phone did a reboot automatically and booted up.
Then the phone started to shut down and restart automatically while it was in sleep mode.
Then i flashed stock mm again. This time it worked. But the phone keeps restarting. It does only restart while the screen is locked. If i double tap or use the power button to unlock the phone nothing happens and the screen keeps black and then the LG logo appears and phone boots up.
Tried different custom kernels, recoverys and rom. Issue is still there. Thats why im thinking its and hardware issue and battery is faulty.
Sorry for bad english
@sakarya making this step properly won't harm you G3 in any way, it'll enhance the power connection because the connection is made by glue and with high temperature it becomes faulty, so yes you can give it a try but before going that far if your not familiar with soldering i recommend you to download and flash a stock firmware from here then go to this page and download the proper firmware you need. since you have this problem when the screen is off, in my case it was random.
You'll find here a guide on how to flash a KBZ properly.
Good luck

Thank you. I will try this.. Bought yesterday a new battery, problem does still exist. Must be a software issue.
Paper trick wont work for everyone. Solder or use a bit of foil and paper for pressure.. I prefer to use a bit of tape as it is a cleaner solution. Batter life seems to fall a bit, just a tad after this mod tho but no reboots fixed 3 out of 3 batteries like this.
The chinese batteries run down quicky.
The anker batteries that also have the reboot issue can be fixed by using the board from the chinese on it fix 1 out of 1 anker this way
Hey, months ago my battery was swollen up I decided to change it so I ordered a new battery.. A few days back I got my new battery *original* after replacing the battery I found that my fingerprint sensor button isn't working when I touch.. The only thing I can do with it is just press it.. Pressing the home button works but nothing happens when I touch it..
Please give the solutions guys I changed the roms twice even flashed the stock rom.. But nothing happened..
Please share the answers
Reopen your phone and check near the home button, you may have dislodged/damaged the connector that goes to the sensor. If it's just out of place, take it out and put it back in, making sure it snaps in properly. If it's torn somewhere you will need to order a new one.

It won't be a wire, it would be a ribbon connector, like this: https://www.ebay.com/itm/Boton-de-I...hash=item33ea2b57dd:m:mcafy4h6tL2vnIt0TJT6vaw
If you're sure it's not broken, just pull it out and snap it back into place. Wiggle it a little to make sure it's not loose. Then put your phone back together and check.
Hi all,
I have a general hardware problem with my Samsung Galaxy Tab S4. Maybe someone here has an idea or tip for me.
I still used the factory software without any rooting or unlocking the bootloader. So everything original and up to date.
A few month ago the tablet began to restart in the middle of using it. At the beginning it happened seldom, but then more and more often. Also during the restart new restarts happened more and more often, so that it took several retries, until it started again. Now it is not usable anymore, because it is not running longer than a few seconds before the next restart if it happens to boot completely at all.
I was able to make a factory reset but this didn’t solve the problem.
My first theory is, that this could be a problem with the battery, that it is slowly dying and had more and more problems to hold the voltage. But the problem also exists when the power supply is connected. So I am not sure if this rules out the possibility, that this could be cause by the battery? Does somebody know how this is internally wired, if a broken battery could still have a negative effect when the power supply is connected?
Do you have other ideas/advices, what could be the problem or would could be helpful to do?
Thanks in advance for any help.
Best
The USB power input can't sink enough current to boot it or even run it without the battery acting as a reserve during peak usage spikes.
Replace the battery and go from there.
Thanks, then I will try this.

Hi Vertex, have you tried this already? I have pretty much the same problem and the battery was also my first intuition, but I don't know if buying a new one is worth it. Thanks!
Hi,
unfortunately I didn't had time to do it yet. I want to change the battery myself and for that I will need time and somebody to borrow me a hot air gun, because everything is glued together.
I will report, when I have done it but it will be at least a few weeks.
Alright, so I'll probably try it sooner, I'll update after replacing the battery. Also, if you haven't tried it yet, you might want to try just disconnecting the battery from the motherboard and connecting again after like 20s, I've read that it sometimes resolves this problem, but it didn't work for me. Fortunately removing the back lid of tab s4 is pretty easy, I used hairdryer, so with heatgun it should be even easier.
Thanks for the tips. I am currently on vacation but when I am back I will also try with a hairdryer.
Any additional tips for removing the back lid to somebody doing it the first time beyond what you can see in the youtube videos? How do you glue it back together?
Hi, sorry for the late reply.
I have eventually replaced the battery, and nothing changed unfortunately… I did a factory reset, etc. However I also had an issue that you didn't describe in your original post, which is that USB connection is not working, it only charges the battery, when connected to the PC while booted it's just not visible at all (tried with several cables, two computers, on windows and linux), when in download mode it kind of shows up, but it's not recognized and no drivers or any solution that I've found are working, so I don't know if it's still hardware problem something with the USB related parts or something in the system on lower level. Well, I'll be trying.
About the back lid. Beyond YT videos only thing that comes to my mind is patience. About the glue, you have few options and it depends a bit on how removing the cover goes. 1) glue stays in the more or less same condition as before removing the cover - that's how it went for me - in that case you can just reuse it, just by closing the cover and pressing it down for some time, it's probably not as strong as new but for me it worked just fine, especially if you use a book cover for the tablet there won't be a problem.
But if the glue came off, wrinkled a lot, or just doesn't stick anymore, 2) you can either use a special epoxide glue often with signature like T-7000 or T-800 but if you just look for a glue for smarphones you'll easily find it. Or 3) Buy a special sticker for this exact device which has a specific shape, it's pretty much the same thing as is used by manufacturer.
