Hello

is there any chance a kind person can help me with this dead stick?

a few information about this phone:

- as far as i was told, the phone died after an update

- when i plug the phone to the charger nothing appears on screen

- when i power the phone nothing happens

- when i volume up + power the phone nothing happen, same with volume down + power and volume up+down+power

i have installed the lg tools and using the imei downloaded a 600+MB package which should be the restore image of the phone but when the procedure starts to flash the image it gets stuck at 4% trying to connect to phone without any luck

if anyone has some ideas to give i would be very happy to try them!
[LG Optimus L9 P760, P765, P768, P769] noob.gamer:
the phone is dead. does it get hot when you connect it to the charger for some minutes? if yes, then it has shorted inside and you have to replace/repair it. same thing happened to my p765 and i had to get it replaced from lg.

Did you try to remove battery for a longer time and put it back? You can also try to remove SIM and SD card before inserting the battery.
[LG Optimus L9 P760, P765, P768, P769] mstation86:
thanks both of you for the replys.. makes me happy to be able to discuss this problem with someone..

i have been doing more testing. this are the new things i found out..

i have discharged the original battery by using it on a small circuit i have.. i then tested it with the tester and it was really low.. then i placed it back in the phone and left the phone charging all night to see if it would heat as noob.gamer said but it didn't.

interesting thing is that the battery is now charged again.. so i opened up the phone to look with the tester inside it..

looks like the charging microusb port works.. i can read about 5V on the pcb right where the connector is.. then i can read 3.3V right where the batter connect is.. when it is under charging, on the battery connector i can read much more than 3.3V which makes me suppose that the pcb is able to charge the battery afterall..

i just really can't understand why this thing doesn't give any sign of life.. power and volume buttons seem to close well when i press them, i can hear a small click.

is it possible that the phone motherboard can still charge the battery but has burned components on it?

components don't look very neat tbh, they all seems to have a black melt around.. here are some pics i did with another phone, sorry for quality

hope you can see what i mean, some chips have rounded borders and seem to have left some black liquid around them

Are you able to go in SW Upgrade Mode?
[LG Optimus L9 P760, P765, P768, P769] mstation86:
sorry, how can i do this?

do i have to enter software upgrade mode to be able to use the LG tools correctly? because this might explain why i wasn't able to flash it when i tried..
[LG Optimus L9 P760, P765, P768, P769] Roker1:
You have to press vol+ and then connect to usb(holding vol+), of course you have to be in SW Upgrade mode to get lg tool working

After you connected it, open LG tool and wait that it recognizes the phone
[LG Optimus L9 P760, P765, P768, P769] mstation86:
bah, sorry.. i have actually found a proper guide now here on xda.

so unfortunately i think i have a bigger problem here.. i have downloaded the universal lg drivers and installed them on a new computer, just to be sure to do everything from scratch correctly this time, and i then downloaded the lg support tools.

i started the tools which say the phone is not connected.. i then connected the usb to the pc.. then pressed vol+ and while it was pressed inserted the microusb to the phone. i tried it twice with the battery on and twice without the battery on.. (sd and sim are not in the phone)

unfortunately windows (xp) doesn't seem to recognize any device and doesn't install nothing. no new peripherals are detected in the device manager.

the lg suppor tools keep saying that the device is not attached and this btw was what i had with the other computer (when i just connected the phone without going into sw upgrade mode)..
[LG Optimus L9 P760, P765, P768, P769] Roker1:
Try to install drivers from lg tool, just to be sure that are right.

You should try also with another pc (win7) if you have this possibility, its strange that the tool doesnt recognize your phone in SW Upgrade Mode
[LG Optimus L9 P760, P765, P768, P769] mstation86:
i think there isn't much left to this phone sadly..

as you suggested i tried on another windows pc, this time 7.. i started directly the lg support tools and clicked on install drivers.. choose the lgp760 drivers and it downloaded them and installed them.. then i tried connecting the phone to the pc with the vol+ button pressed but nothing happens still..

is this sw upgrade mode suppose to start even without the battery?

edit: i tried rebooting the pc but still nothing has changed.. :(
[LG Optimus L9 P760, P765, P768, P769] Roker1:
I dont know, try, if you read SW Upgrade Mode on the screen it means its possible also without battery (i did this always with battery in)
[LG Optimus L9 P760, P765, P768, P769] devilanuj17:
can u tell how ur phone died..? while updating sw or rooting or it died due to heating?
[LG Optimus L9 P760, P765, P768, P769] mstation86:
actually the phone is not mine. the person who gave it to me just told me this exact words:

"i was using the phone and received an update.. i downloaded it and installed it.. then i used the phone a 2 days and then it didn't work anymore."

this is all unfortunately.

when i try to start in sw update mode, nothing appears on screen.. i don't even hear the phone vibrating or making sounds.. nothing at all.

really looks totally dead.
[LG Optimus L9 P760, P765, P768, P769] devilanuj17:
try claiming the warranty. ..? and dnt mention root dev kdz words to them..just go ang say what your friend told u exact lines..and if u had open the lg l9 then pls screw it well and undetectable..and if possible..try sending a girl/older age(max 40 lol) woman to the lg service centre representatives..cuz they wont doubt a female doin root\black ops stuff on the phone..

remember there's a limit to xda work. .and that ends at hardware problems.
[LG Optimus L9 P760, P765, P768, P769] PPCC01:
Funny thing, my p760 died yesterday with about the same symptoms and no way to get any vital sign of it. With the difference that the last update I did was like 3-4 weeks ago.

In my case seems like the back-top area gets a bit warm when charging, but I would say that just the usual. It might be, like someone said, a short circuit.

I guess it will not be a problem claiming the warranty and getting a new one. However I will not take the thing apart to be sure.
[LG Optimus L9 P760, P765, P768, P769] OperationNT:
If you remove the phone battery and then, plug your phone to your computer, is there any signal on the USB port ? For example, on Windows, you should here a sound like if a device was plugged, unplugged, then plugged again, unplugged...

See this thread for more information :

If you don't have at least this reaction, you can assume the phone is really dead. Otherwise, you have probably a software issue with the bootloader or an hardware issue with the phone battery.
[LG Optimus L9 P760, P765, P768, P769] PPCC01:
My bad, it is actually alive, and exactly as you said. I guess i didn´t press the combination properly :S. Seems like I might be able to update via "LG Support Tool" (vol+/power/usb). But first I need to try a backup, I would like to keep at least some photos I have on the phone.

Lets see if the sync software is able to do it...

---------- Post added at 05:32 PM ---------- Previous post was at 05:18 PM ----------

:/ As I expected the PC-sync software did not connect. And I don´t see any option to backup with the "support tool". Any options?

I suppose, the internal memory is just a memory card and I could just copy directly from the card, but I don´t want to take the phone apart (just in case a have to make use of the warranty in the end...)

Thanks in advance.

---------- Edit ----------

Well, the thing didn´t work out in the end. I tried upgrading with the "LG Support Tool" but the process never went further than 4%. :(

I will just return it, and I hope to get it back soon (or a new one... or whatever). In the meantime I can go back with my always reliable N5800 :D

Every ten or fifteen minutes when using the phone the router will reset. So I don’t just lose the wi-fi on the phone I lose my desktop internet connection. I have the latest firmware (1.35NA) for hardware version A4. ???

[One (M7) Q&A, Help & Troubleshooting] Tanquen:
I guess were just SOL. I’ve looked around on the net and the HTC One X and S had Wi-Fi issues also. This seems like kinda a big deal. Are they going to fix it or whenever you go someplace with a certain brand or router your just screwed?

I’ve had my router for some time now and none of mine or any of my friend’s laptops or phones or printers caused a problem. I was really hoping this One was the one but I guess it is getting returned.

Hackers?! Who needs em, I just walk around with my HTC phone and reboot routers.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
Spent some hours with Sprint and HTC but they say they have never heard of the issue and just want to replace the phone.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
Been looking around some more and it looks like the other ‘One’ models had Wi-Fi issues as well. I’ve tried some suggestions. Disabling WISH and QOS on the router seems to have made the dropout less frequent but there are still fits of them. Others also said to use WPA and not WPA2 and try a different Cipher but you should not have to do this just to get a new phone working. No other device has had an issue with my router or its settings. I guess I’m the only one though. Maybe no one uses router at home with encryption and passwords just free or open hotspots.

I also have this problem and the only fix i found for it was to set my router to use wireless G only, something with wireless N was causing the reboots on my router..btw i i have a dlink extreme N router...hope this helps u
[One (M7) Q&A, Help & Troubleshooting] slackercow:
not to take this slightly off topic, but i have never had any good luck with dlink routers and wireless devices in general. i thought comcast was to blame for all of my internet issues, but they were all solved when i switched router brands.

not saying the phone and router shouldn't play nice, i just think the dlink brand of routers in general has these issues. cisco/linksys and even asus have worked a lot better for me. i own the dir-655 and that thing has never been able to handle wireless traffic without dropping connections constantly (to laptops, apple and lenovo, to tablets, nexus and ipad, to phones, iphones and a variety of android devices)

[One (M7) Q&A, Help & Troubleshooting] godutch:
If the router resets, it's a router issue, it shouldn't do that, whatever bad signals are sent to it, especially if you have remote management turned off

[One (M7) Q&A, Help & Troubleshooting] Tanquen:
You’re are not wrong but I don’t see lots of people saying that the DIR-655’s 802.11n don’t work. I do see lots of people with HTC One, One X, and so on with Wi-Fi issues. The DIR-655 has been out for a while with no more firmware updates. No other devices have this issue and I had the DNA for a time and used it on the same router without issue. Just got a message from DLink and they just act like HTC. Have you tried other 802.11n devices it must be the phone that is at fault.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
Well I've never had this happen with any of the many Wi-Fi devices I've had. I even had the DNA for a time a few months ago and it did not do this. I know the feeling when you come to the conclusion that one brand sucks but I’ve found that they all can have issues. I’ve been reading up on new routers and seems like Asus has issues, even read a review where they had dropped connections. Maybe they were in a bad spot. Maybe one too many of my neighbors is clogging up the Wi-Fi now. ??? I just know this is the only device that has done this and as usual all the manufactures involved just point fingers.
[One (M7) Q&A, Help & Troubleshooting] tws101:
D-Link sadly makes unremarkable garbage. I have found that most residential router models are very bad....

I now use commercial grade Mikrotik routers that

cost less

than the Residential routers. The Mikrotik router NEVER goes down.... I have an up time that is 1.6 years and that was its installation date. I probably should update the firmware, but why reboot it.... It's working fine.

Models like this one RB/751U-2HnD are great.

I have been having the same problem. WiFi drops every ten minutes or so. The router doesn't reset though, I just lose signal and have to turn WiFi off on the phone and turn it back on again I know the WiFi still works because my husband had it working on his iPhone at the same time mine drops. I've only had the phone since today and I need to have WiFi work because I don't get a good signal at my work. There gas to be done sort if software fix for this problembecause I see a lot of posts about this same issue.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
Well I've-

Set the phone for Best Wi-Fi performance, uses more power.

Disabled WISH & QOS.

Restarted the phone and router a few times.

Today I'm trying:

Set the phone to 2.4GHz only.

Set a DHCP reservation for the TCP/IP address.

The next step would be to use 802.11g only. :(

[One (M7) Q&A, Help & Troubleshooting] Tanquen:
That's lame but I don't get why my HTC DNA did not seem to mind the DIR-655. Did you try to re-flash the router? Going to 802.11g only takes me down to 20MBPS from 27 with 802.11n.

I could not tell the difference. With N only setup and everything at auto it would just show 55-65 Mbps in the router status. I forced the transmission rate and channel width to the highest settings and while the Mbps on the router status page would then show 130-150Mbps it was still just as slow. The Wi-Fi analyzer on the phone still showed a 65 Mbps connection. ???

I have a I9000 and 2 laptops working on G and N, no problemo.

Just yesterday evening it appeared, after about 10 min, no Wifi, and couple of seconds later it reconnected.

Strangest thing, never had this before on any other device, also my son and his girlfriend who have a S3, no problems.

I've had this problem on my DLINK DIR 615 with my original HTC INCREDIBLE S and my HTC ONE and the only way I found around it was going to the advance settings of your wifi menu and make sure wifi best performance is on. It will drain battery power but it will maintain connection on router with out causing the router to fail.

Hope this helps

I had this exact same router, and ny wireless was dropping constantly, I had done everything everyone said on dlink support forums, to any other site that Hamdan suggestion. I had enough, reset to factory defaults the thing,made sure qos, dlna, and reserved ips and it was perfect. Hasn't dropped in 5 days.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
This was already mentioned and will not help with the HTC ‘One’ WiFi issues.
[One (M7) Q&A, Help & Troubleshooting] Tanquen:
Reset the router to factory defaults? Made sure what about QOS and DLNA? I’ve tried disabling QOS and using a reserved IP address and it still drops. Again, other 802.11n devices work fine with this router. There are to be some WiFi updates in a new HTC One firmware and the newer OS but I don’t know when/if Sprint will get them.

The only thing that worked for me and others was to disable 802.11n and use 802.11g. Both are faster than my internet access so it's not that bad but it bugs me that the Wi-Fi chip in the HTC One is not standard.
[One (M7) Q&A, Help & Troubleshooting] soul40k:
Yes, to defaults, QOS and DLNA off, I didn't actually reserve IP's this time, where as before I had it on everything. I have 4 N devices working including my HTC One, as well as multiple G and even a B working :-\. Only other thing I can think of other than that, was to make sure my password was TKIP and AES, Auto mode (WPA or WPA2), and that I kept it on Auto Channel.

Honestly, I had nothing but ****ing problems when I started fooling around with this router, everytime I changed a setting from auto, it decided to take a dump. You wouldn't believe how absolutely pissed and amazed I was when I reset it to defaults and left everything auto, and it started working properly. Most likely the last time I am going with D-Link too, their support and updates blow for all of their routers.. They don't update firmware, they just pump out a new product version.
[One (M7) Q&A, Help & Troubleshooting] Prod1702:

not sure if i should say that i'm glad to find this thread as i'm also having wifi issues with my t-mobile usa htc one and the d-link dir-655. for me, the wifi signal will drop all the time, especially when i'm trying to stream video (netflix, youtube). prior to getting this phone, the d-link router has been flawless with all other devices in the house including iphones, ipads and my 2 previous htc phones (G2, HTC One S). it just sucks that i might have to purchase a brand new router just because of this phone. it's either that or hope that htc/t-mobile releases a driver that will fix the wifi problem. to me, it seems like the 802.11ac chip in the phone is very picky as i was able to use the wifi with no issue when connected to the HTC One S as the hotspot.

the t-mobile version of htc one is currently still on 1.27 software and it doesn't appear that 1.29 or newer versions address any wifi issue. so i may just have to either bite the bullet and get a new router or stick with mobile data only at the house.
