Hello guys,
I have a LG G5 H850 since the release in the UK with Vodafone.
Last week, got an update On The Air to the v10c, but then my power button suddenly stopped working (or it is a big coincidence)
Symptoms:
- When the phone is off (battery removal), can't turn it on only with the power button. Only way is to plug it to the USB cable and it automatically restarts the phone (so weird.....)
- When the phone is on
--> lock screen activated, I can't unlock it by pressing the power button.
--> lock screen not activated, I can't lock the screen manually neither by pressing the button.
Also, the fingerprint sensor works perfectly fine....
I tried the following to fix it without any results:
- Hard reset (Factory reset) through the settings
- Safe mode to check if an app could be the reason...
- Wanted to try to flash to the factory v9h rom but could not find it unfortunately.
I tried to contact LG customer service but they answered me 3 days later with a pre-made answer for the G4
Anyone experiencing the same issue ?
Is it hardware or could it be software ?
Any other things I can try ?
Cheers
Lyn.
I doubt that this is a Software relatet Bug, otherwise it would turn on using the button once the battery was removed.
I guess you can't reach the download mode either, otherwise I would recommend you to flash the V10a kdz and Cross your fingers.
Swapping the phone in a local Store isn't possible? If so, try it.. You won't get a repaired phone in near future as the repair facilitys don't have the needed parts yet and you'll be stuck with no phone for a while.
Thank you for your (quick) answer Savoury.
Yes I have some time to loose tonight, I will give it a try to this older version if I manage to find the kdz.
Keep you updated !
Cheers
Power button / fingerprint scanner just stopped working on my LG G5 tonight.
Don't know if it's related or not, but it seemed like I had just wiped the phone clean with a Wet-Nap just prior to the button failure.
Weird, because I've been using Wet-Naps to frequently clean all of my phones for years,
and never had an issue before. I attached a pic of a Wet-Nap for reference below.
Also, when I go in to SETTINGS and search FINGERPRINT, nothing comes up in the SETTINGS for adding or removing fingerprints.

Strange development:
As of this morning:
-the "fingerprint" option has returned to my settings
-the fingerprint scanner will unlock and turn on the phone again after going through the setup process again
- the power button will NOT turn OFF the phone's screen anymore
Any explanations ????
Here's my answer I just posted on another thread. Hope this answers your question. I had the same problem. Nothing I can do with it now and it was out of warranty. Still works fine. Just a nuisance.
"Hi there just wanted to mention my experience from today. I bought a g5 with the power button not working but the fingerprint scanner did. I ordered a part from eBay and replaced it fine.
Then when I put it back together, it wouldn't turn on still. I took it apart about 3 times and tried to redo it until someone online mentioned to clean the gold pins with rubbing alcohol... Well I was getting ready to do that when I looked at the pins on the motherboard that makes contact with the power button part and.... A gold pin was missing. A drop or something must've made it fall out. I barely touched the one next to it and that one fell out. It had a hook that went to the underside of the metal thing and it popped out of my tweezers and I was never able to find the piece after that....
What a dumb design that they made. Those pins should not be there without being attached to the metal that's there"
I bought a refurb G5 and power button would only turn off the screen if pressed 4 or 5 times in a row. But I was able to fix it by simply taking a Q-tip with Isopropyl rubbing alcohol and pressing the button down while giving it a rough cleaning. What happens is that fingerprint oils and other gunk get stuck inside the button but after you clean it out with alcohol it was working good as new.
May take 3 cleanings total to restore it back to 100% performance. But certainly try that before swapping out any parts. This is a known issue with the power button on G5 and a cleaning with qtip and alcohol will fix the problem 90% of the time
I fixed this buy buying a new button. I installed it with a phone repair kit, a blow dryer, and a new button.
You can find them on amazon. You'll find a few videos online on how to do it. It's an easy repair.
The hardest parts are getting the phone apart (careful about breaking the thin material at the edge) and heating the glue to remove the existing plate covering the button. Consider buying a new plate for this button too, as you may damage the old one taking it off. You might need a high strength glue to reinstall the plate.
It works like new now, even though my phone GPS is toast regardless lol.

My radio rom is GSM 02.19.21
I've configured my network in Network Setup Wizard, but it didnt helped.
My Prophet keeps popping up with Insert SIM card screen. I have to turn off phone(turn off phone signal) to make my Prophet work. By doing that, I cannot make any calls, but still be able to use other functions. And one thing is that the orange led is always ON !!!
Try and flash back to a WM5 Shipped ROM.

If nothing was being help by software,
Try .......
1. remove the sim, clean it a bit and put it back or
2. if the contact of the hardware is bad, try to put something a bit less then 1mm thick (like folding up a small paper) on the sim, put the battery back to force it tight, if you are lucky, it will be your temporary solution.
3. try to use the sim with other phone to double check if the sim was dead....
Good Luck

Not working too...Somebody help me please???
I had a similar problem a year ago. As dioxda2 said, take the sim card out, clena the contacts on the sim, and pull up with a pin, or similar, the contacts that are built into the phone.
I had just had the touch screen replaced the day before (the tech centre was literally round the corner from my work), and I was getting this message all the time. the technician did what I described, as he told me this was a common Prophet issue.
And it's been fine ever since...
This post is almost a year now.
Ok, I've figured out the problem. I bought second hand Prophet and there was this problem. So, I took it to the mechanician and he told me that my Prophet is damaged by liquid. I was surprised because the previous owner didn't told me so. The mechanician told me that look at the sticker at the back where the Sim slot is located.
"If the sticker is plain white, then it is fine. If it is pink, then it has been damaged by water."
The problem cannot be fixed. The mechanician cleaned my Prophet, but nothing happened. I was pissed off because this is my first WinMo device. So I took it and turn it on in the sink full of water. It vibrated, screen flashed, all leds shining and died. Later, I leave it dry and turn it back on again and it was fully functioning except my Sim card is not detected. I was shocked of the quality build of Prophet. I want to test how long it will go; I put it in my sink for several of times, same result happened but it is not dead yet. It was immortal device indeed. I took the only functional thing left, the battery, and throw away my Prophet as far as I can. Bye bye... My Immortal Prophet.
Anyway I bought it for around 100 dollars. This is quite an expensive lesson for me. If you guys are going to buy a second hand device, please make sure you check everything especially the sticker at the back!
My tablet will not boot any farther than the Viewsonic Birds screen. At first I thought this has to be a software-related issue. That being said, I've tried every single possible combination using nvflash to no avail. Today i decided to take a closer look into my tab and noticed on the docking station connector connecting to the system board, one of the wires were clipped. Now because of its position (fifth wire from the left) I at first assumed it came that way (not sure why I thought that but yeah...). Once I found a high-def picture of the tab's system board untouched I realized this was not the case and I somehow clipped it upon taking the tablet apart. I attached a picture of the one I found with a red arrow pointing to the wire in question here.

Does anyone know what exactly this wire is responsible for?
Is it possible that this wire being cut is causing my tablet to get stuck at "The Birds" screen?
Also, has anyone had any luck with getting their hands on any schematics or wiring diagrams of the gtab?
Has anyone done something similar to this, and how were you able to rejoin the cut wires (with them being such a small gauge)?
If this wire is the culprit (which I'm praying is the case, so I atleast know the problem), my best guess is because upon boot-up the OS goes through its checklist and once reaching the docking station connection, this wire being cut halts the boot-up process hindering me to go any further. That sound like an accurate assessment? I'm just trying to understand the issue as best I can.
Any insight would be greatly appreciated, Thanks!
I really don't see that as being an issue.
When did you open the tab up? Before or after boot issues?
Have you hit the internal reset button?
Have you double checked your nvflash files and stock image to make sure they are correct for your system/Gtablet?

Both, first time I opened it everything went smooth and started right up after back together. Second time was so I could put a dab of MX4 thermal compound on the tegra2 chipset, and ONLY on the chip; none on the board. After back together, it turns on but freezes at 'the birds'. During this whole thing, I had BoS 5.2a loaded.

Since this started, only every time Ive tried anything related to formatting (format all.zip), or nvflashing.

I have tried flashing back to bekit's stock (pre 4349, how mine came) and stock 4349 1.2 (since I was on a 1.2 BL at the time). Between every flash, I've hit the hard reset, ran the FORMAT ALL.zip, then preceded to nvflash.
Its also hard for me to believe this is somehow a hardware issue. Seems to me if it was, the tablet simply wouldnt turn on or I atleast wouldnt get a picture. One interesting thing roebeet brought to my attention was that eventhough it freezes at the birds screen, the little black bar along the bottom still pops up meaning the kernel is even being recognized, then it freezes. It would be nice if I could know the order precedence when this tablet is turned, as in the checklist the soft/hardware go through. Maybe that could help with narrowing this problem.
Anything else you can think of, please let me know cuz I'm almost at wits end.

Actually, weird things tend to happen in regard to hardware issues.
I had a laptop that I dropped from 3 foot up. Drag and drop function stopped working. Half my keyboard stopped working, but only for certain programs. Some boots resulted in the taskbar not registering until I control alt delete to bring up the task manager window. At first, I really thought these were all software issues. But after reinstalling windows for 3 times the same damn things kept happening.
So, yeah, hardware issues do result in weird software issues. It's like hitting yourself on the head with a hammer. It's a hardware issue, but you might end up a little cukoo afterwards.

Yeah, hardware issues like that I'm accustomed to having 15+ years experienced working on/building oem/aftermarket systems and being a pc technician by day. But this issue is getting harder to believe it is hardware since A)The wire accidently cut belongs to the docking port and B)The symptoms its exhibiting are the exact same symptoms I've experienced with my tab in the past before opening it at all. But with that being said, I dont know what else I can try on a software level.
One thing I thought of last night that I'll try sometime today is just trying to install bekit's stock 1.1 ROM from my external sd. Read somewhere that the internal sd has gone bad on some gtabs. Dont know if this will work since nvflash seems to flash properly, it just doesnt reboot and I dont know what else to do at this point. Thanks for your input though.
Hi,
Ok so I decided to fix an annoying little rattle I had with the battery today. I opened up the 2 screws, slid of the cover and placed a little foam between the battery and chassis. Job done. Then I spotted a switch here

}
So I switched it (Yes the Tablet was off) and then I switched it back the other way. Put it all back together and attempted to power up. No good. Dead. Held the power button for 10 secs and still nothing. Plugged in the charger and lights flashed then could power it on. The battery was already fully charged and also indicated this when successfully powered on.
SO what did I switch ?
Sony Tablet S 16GB Wifi - rooted
Any one any ideas ?
Do you mean it works when plugged in? but not on battery? If so what percentage charge does it show - maybe try measuring voltage on battery - preferably direct if you can open the case again, or try some soft first - I saw som widgets etc measure voltage, temp etc - I don't use any of them so cannot recommend. I believe setting menu has battery status too but I believe it's just stating its state or something simple like that not the voltage.
It works perfect now, it only didn't switch on the first time till i plugged in the charger. Now it works fine all the time. If you look at the picture the word OFF is printed on the PCB next to the switch. I'm really just curious to know what it switches off.
wtf... could this be like a manual s-off switch?
Would you be able to re-post the picture? It's not showing up for me (could be the work computers though) Or a link perhaps.

I wanna check this out myself when I get home, but firstly, how deep did you have to go to get to this, and did the rubber feet go straight back in easily and stay inplace well? Don't wanna have them falling out all the time
Here you go
or here too
taking the rubber feet off was a little tricky. I used 2 nail files , one to push the rubbber from the edge of the hole and the other to lift it out. They are quite sticky and go back easily.
Check this out as it might help

I had a look at the pictures on the link above but still no mention as to what this off switch it for.
There is a switch inside the asus transformer that kind a looks the same and it is for the batery, when your device does not see your batery anymore than you can use the switch to deconnect and connect your batery again without removing it.
When the batery drops under a certain voltage the tablet wont reconize it anymore and than you need to do this.
I think when pulling the switch you"removed" the batery, that is way you had a scary startup after that
Is possible to add a better battery?
The battery is completley removable so it can be exchanged. Its only a matter of waiting for one of the after market battery makers to come up with a bigger battery to install.
My Atrix seems to have a significant problem hopefully someone can help with. I dropped my phone and my screen had some issues when touching certain areas (ie. It wouldn't register as a touch during any app in certain parts of the screen)...so I replaced my LCD and Digitizer, and no luck, similar issues. So today I replaced the ribbon cable with a new one(with power button, front facing camera etc) ,and STILL the same issue.
I've tried new Roms, and done fresh/clean installs of everything but I've no idea what else I can now do, please help?

Although it doesn't make much sense, you may need to try the PDS partition fix. You'll need to google that and find the files and tutorial for fixing it.

Hey really appreciate your quick response to the issues I'm having.
I have tried PDS Partition Fix and unfortunately this hasnt helped ... both methods were followed to the letter and nothing the same issue applies.
Dont suppose there are any other suggestions that anybody can come up with?
I am thoroughly grateful for all your help!!

Only other thing I can suggest is warranty.
when you replaced the lcd and digitizer did you clean it very well between them? I have seen the slightest amount of dust disturb the digitizer, also when holding the phone upright is it the "e" "s" "d" "x" area of the keyboard that is acting up?
Moreover
Unfortunately, the warranty is now void since unlocking the bootloader, which I knew was a risk. I cancelled my insurance too since the policy excess was ridiculous.
When replacing the digitizer I cleaned the connectors using a microfibre cloth, the ribbon cable connecting the digitizer to the board was also replaced, so potential board connector issue?
Its random, what works...if the screen was in quarters from top to bottom then quarter 1 and 3 do NOT work...so i cannot pull down notification bar unless I rotate screen, and use a working area of the touchscreen. But thanks to Go Launcher I have set up a swipe gesture for notifications. And thanks to perfect keyboard I can change the height of the keys so I can at least send a message. But this isnt ideal, since the keys are so small.
Any other thoughts on how to clean the connector properly or anyone experienced the same?
the digitizer connects to the speaker ribbon cable and then goes to the board, but that ribbon cable usually doesn't get damaged.
you can reflash a vanilla 4.5.91 and possibly not brick and if it comes back it wont show the unlocked text I don't recommend this due to some people experiencing hard bricks doing it. But then you might be able to return it.
you say its random, so does the entire screen work sometime? or is it always quarters 1 and 3? if its not changing I would say its a bad digitizer.
Well I've tried 3 different digitizers so I know this is not the issue.the change of ribbon cable was merely a stab in the dark. Its random the places that doesn't work, but ALWAYS the same places work/don't work...so quarter 1 and 3 DON'T, but 2 and 4 ALWAYS do.
How might a reflash work? I'm 99% certain this is now software related...my only other theory is the mainboard may be damaged in some way.
Reflashing may be an option, this is my current set up...I've upgraded the radio so whether this will cause issues I've no idea ...

it won't fix the problem but it is a way to remove the "unlocked" text from when you start up the phone, or are you completely out of warranty / no chance to return ?
HELP! "Ghost touch" (Screen unresponsive when it randomly occurs)
Ok, the best way I can explain what happens to my screen is a "ghost touch"
As in, sometimes when I'm using my phone, there will be a spot that gets stuck on my screen; just like if I was holding one finger on my screen.
This causes my lockscreen to be unresponsive, and even _if_ I am able to unlock to my launcher, I cannot press any buttons at ALL!
I turned on the (Developer Options - Show Touches: "Show visual feedback for touches") when I had a hunch this was happening, so I could try and diagnose where on my screen it was "touching"
This is a screenshot of where it happens:
{
"lightbox_close": "Close",
"lightbox_next": "Next",
"lightbox_previous": "Previous",
"lightbox_error": "The requested content cannot be loaded. Please try again later.",

"lightbox_toggle_sidebar": "Toggle sidebar"
}
It's on the VERY far left of the screen. And I have never dropped my phone, I take very good care of it - and it's been in an Otterbox since week 1.
If I touch it when it happens and slide my finger directly up and down; Upwards: it goes about just under the status bar, and Downwards: it goes a little above the lock ring - any further and it snaps back to the same spot.
I _just_ dealt with this for about 30 minutes prior to me writing this post from my phone right now. I had to keep holding the Power key and doing a faux "battery pull" (force restart) - I would try a normal restart, then I would reboot to recovery, then TWRP, wipe my cache/dalvik, carefully clean my screen with lens cleaner liquid (for contacts and glasses) with a soft cloth, using very little liquid as to not get any inside the phone/screen (trust me, I know you're thinking "Oh this dumb guy just got liquid in there and that's whats causing this!" - That's not it! lol)
And as of right now I'm able to use my phone fine, but it _really_ [email protected](king sucks when I get a phone call and pull my phone out of my pocket and am unable to answer my phone because of the "ghost touch" - then I have to spend another 20-30 minutes going through my reboot/clean routine until it works again.
Any suggestions? Has anyone experienced this? (With this phone or any other device?) Should I bring it to a Sprint store? or should I just say "screw it" and get a new phone?
Only problem with getting a new phone, is I plan on switching from Sprint to Ting (Ting uses Sprint towers, and is a pay-as-you-go type of plan) and Ting only allows a VERY small list of devices to be activated under their plan. The Evo 4G LTE being one of them. And if you purchase a new phone from Ting, they charge _FULL_ price (even more I think, for example: I believe a new iPhone is $700+ from their website) and I'm not spending that kind of money. Also, I can't get an upgrade from Sprint and renew another 2 years, so I don't think I can even get a new phone
Anyway sorry for rambling on, I'm just upset... This ghost touch BS is really pissing me off. I want a new phone and can't get one, without paying full price AND has to be on Ting's list.
HELP!
P.S. It's my birthday today, Happy freakin' Birthday to me huh? lol - zmag
Buy a used EVO from eBay. Expect to spend about $70 - $90. I had to replace mine just a few months ago.
My wife and I are both on the same ting plan and our highest bill so far was $43. Not sure what you're paying more, but you'll probably break even in 2 months on Ting. Happy birthday!
Sent from my EVO using XDA Premium 4 mobile app
Yeah I'm probably gonna bite the bullet and go in a different direction (thinking galaxy s5, but if I buy from Ting now it's $597)
Or you gotta wait 1 year from release date to use Ting's BYOD - dunno what I'll do yet
Thanks! - zmag
I seem to have found something out about this...
Out of pure frustration, I took my phone and physically tried to bend it (when the ghost dot appeared) - In doing so, it temporarily removed it from the screen.
Do you think it has to so with the screen touching the sensor inside in that area?
It goes away for 30-60 seconds then reappears (probably when the plastic goes back to that spot)
Any input?
Same thing has been happening with me the last few days. Except that when it happens, the screen goes down to the minimum brightness setting. I usually reboot by holding the down the power button. I haven't tried wiping cache but I think i'll try it next time. Any other suggestions?
