Won't turn on but....... - LG Optimus L9 P760, P765, P768, P769

i have a friends L9 from T-mobile and i wanted me to try and look at it since he knows i love playing with phones. i got it and i tried to turn it on and see what was going on and nothing. i thought maybe it was the battery so i tried my external charger and charged it till the blue light was on. i put it back in the phone and nothing. i borrowed another l9 battery and still nothing but when i plug it into my pc it makes the noise like it know that something is plugged in. now my question is should i still try to get it to work or just say forget it and send it to the grave. thanks for any input.

Blank screen, red light?

Alright so a friend of mine wanted me to upgrade his phone for him to the new radio and all that stuff.
I tried run the official installer but I got an error that the battery wasn't at least 50 percent.
I left it charging overnight, came this morning to see a red light on the device. It won't power on at all. If it's plugged into the USB on my XP system, windows finds a new "Data Interface" device.
Tried doin the resets with holding the camera and power button and all that with no luck.
I've flashed both my phone and my girlfriend's in the past without anything like this going on.. obviously since I didn't get any kind of flash actualy going, I don't think that had anything to do with it.
Anyone know what do with a phone in this condition?
Also, my friend hadn't activated his sprint phone yet, he got the phone brand new from ebay, and had it for about a month or so, but had an overdue sprint bill he had to pay before he could activate it.. so if he took it to the store would they replace it there for him even if it was never activated?
Thanks for any help.

Is that just hitting the reset button? If so, I've tried that but it does nothing.. also tried that while holding the camera and power buttons but that does nothing as well.
If you're talking about something else, then please let me know.
Thanks.
Sorry for the double post, but I should also add that I put his battery into my phone and it works fine and shows 100% charge.
couple things here for debugging purposes.
Check your battery against your friend's for signs of abnormality. (especially leaks/contacts).
If all looks fine and it still doesnt work with your battery, you can try flashing with his battery (though that doesnt make much sense, but try it anyway just in case).
Since you say your phone works with his battery and not yours, it would lead one to assume you have a bad battery, though, you know what they say about assume, it makes an ass of u and me. ha. Anyway, try that and post results.
EDIT: See what happens when you put your battery in his phone, post results.

Thanks for the reply.
Both batteries will work in my phone just fine and both show a full charge. Neither battery will work in his phone, and neither will power up the device.
Both show only the red light when plugged in.
Any ideas?
Ah, i read it slightly backwards. Sorry.
Ok, so when you put a battery in his phone a red light comes on and a blank screen? No noises or any type of error message? Check the contacts on the back of his phone and make sure they're nice and clean, Check the back of yours against his, I think these phones have that open port on them (i dont feel like actually taking mine apart to be sure), and make sure those aren't "shorted" out by anything. If everything looks perfect compared to yours, I'd say your best bet is the phone is broken. (assuming you've tried getting it into bootloader with no luck, softresting and hard resetting with no luck). Let me know what you find under the batteries.
When I have the battery only inside the device, it does nothing, no red light, no screen, nothing whatsoever no matter what I press.
When i plug it in, it does nothing as well, but if I hit the reset button, the red light comes on and stays on until I unplug it. If it's plugged into a USB port, windows detects "Data Interface" but finds no drivers.
I checked the contacts, they look pretty much the same as mine, no signs of corrosion or anything.
that's very odd.
We've ruled out the battery at least. (send me the spare, just kiddin).
When looking under the battery there isn't a little hole for a factory reset is there? (i havent looked under my battery since i got the thing).
If not, that sucks. If there is, push it and see if anything happens.
Otherwise, I can't think of much else aside from a broken phone. Defect of some sort perhaps. I'm going to browse my manual real fast to see if it says anything about a red light, i'll edit this post if i find anything.
Try installing different bootloaders on there to see if anything happens. Also, try the exit-bootloader program to see if that helps. I'm not sure but when my phone has a redlight, it usually means that something is wrong. If all else fails, make that dreadful call to Sprint's technical support. Their customer service is a joke but their technical support can be very helpful.
i cant find anything in my book about a red light. I would probably give Tech Support a call (and tell them to send me their book) and see if they know what it is.
But as the guy above said, try different bootloaders see if you can get anything at all.
have u tired your battery onto his phone or try to see if your computer picks up anything expect data device
I had this happen once, Try this...
1. Remove the battery.
2. Plug in wall charger.
3. Power the device. (this may not do anything)
4. Install battery and wait for yellow light.
5. Press reset button on bottom of phone.
If you still get a red light and no power after that, I would guess that the phone is defective.

Sorry to say, but the phone is bricked...good luck having sprint replace a phone that was bought on ebay.
Please read THE JTAG PROJECT
Greetings,
Please have a look at my thread and determine if this project appeals to you. Remember though, only submit it if you are totally sure that there is no fix for it any other way. Thanks.
hi, im having the same exact problem.. was there ever a fix for it?
thanks in advance
anyone? please helppp!! i just got this phone :[
ive had this happen twice since i got the phone. it happens right when i plug it into the charger, screen goes black and red light comes on. i found that taking out the battery for a little over 10 minutes while off the charger and it will come back on. havent had this happen since i got a replacement though.
Three days after I bought mine, this happened. Had done nothing with it (no third party software, nor rom changes). The tech said to let it sit on the charger over night, which did nothing. They replaced it for being DEFECTIVE.
Slack in my duties but not forgotten
Greetings all,
The symptoms described here are the classic where the bootloader has become corrupt. I am still working on it and have not given up, just had lots on the plate.

Razr completely dead, anyone else?

Hey guys,
My Razr was FULLY charged and in the morning I think I tried switching SIM card and it just died. I thought that volume down + power button would reset it but NOTHING. I tried anything I can think of and any solution on google I could find but phone is completely dead. If i plug it into computer with USB cable, there is a solid light on the phone but computer does not recognize it at all. If I plug the charger, there is nothing, not even light. Phone does not start up in any case.
Any idea? I already sent it back but I am curious if anyone else had the same problem.
Dont have that problem...but it sure as hell dont give us a lot of confidence in the build quality of this phone....hope it never happens to mind coz I dont have warranty for the phone.
can you give more details on "how" you swapped sims?

I've had my Photon 4G get into an odd state like that.
The only way that I've been able to get the phone back to normal, is to remove the battery, let the phone sit for a minute, then put it back together again....
It's only happened about ten times since I've owned the phone, but it scares me every time that it happens.

[Q] SGS2 battery problem maybe?

Hey all,
so a few months ago my SGS2 went off. It was an interesting behave of it, it just started to turn off sometimes, without any reason, without any popups (eg. battery low) or anything. I was really curious about this problem but I didnt have a single idea of what happened to it. Like a week later, it didnt turn on at all. I disassembled it, and found out that my secondary microphones cable broke. I thought that was the problem, so I ordered a new module (which includes vibrating motor, secondary microphone, ear-piece, and the jack).. I waited 3weeks, the first one arrived broken. I waited another month, and today the second one arrived in one piece. I put it inside the device to see if it works but its not. NOW the problem is, like it was before I ordered this module, when I try to turn the phone on, it doesnt do anything at all.(with the broken secondary mic cable it did, it went till the samsung logo and then bam, blackout) IF I put it up on charger, it says the battery is FULL, and from then, I push the power button and it starts to turn on, but goes until the Samsung logo, or sometimes it did boot, but thats rare, and then again BAM, blackout. Now I was like wtf? So i tried to reach recovery, I did a full hard reset to the full stock SGS2 ROM, tried other kernels, recoveries, ROM's, but nothing helped me. NOW If i enter DOWNLOAD mode without the charger, it says "Low battery! Cant download." and this happens right after i plugged the charger out, and it told me that the battery is full (what a liar), but when i plug the charger in, I can reach DOWNLOAD mode, and Recovery mode too, but they do blackouts after a few minutes too...
Any ideas?
Would be happy if anyone could help me out...
thanks :good:

oh and if it matters, its GT-I9100, 2 years old.
if you can get your hands on a different battery, i would recommned you to test it with that too.
as your device is 2 years old and i am assuming you havent changed the battery yet, there are strong chances of battery life getting over.

thanks for your response!
well today i am about to test a new battery, i hope thats what the problem is... an extra thing, and yes im stupid because of this but i left my battery in the phone for the 2 months while it was off... a friend told me that it can cause the batterys death, is that possible?
If u want to leave your phone switched off then it's better to charge it and then remove the battery from the phone. So there is a possibility that your battery is Screwed because of that time when you kept it in the phone itself.

Phone completely bricked, charge light shows only initially

A few months ago, my oneplus x bricked for apparently no reason. I went to the bathroom, came back to my desk and my phone was making a hissing sort of sound from the speaker and then went completely black. Since then, it hasn't turned on. When I charge the phone, the charge light only shows for about 5 minutes and then goes off. I can't turn it on no matter how long its been charged/plugged in. My pc also doesn't recognise it (holding down power button + volume down does nothing). I thought the stock battery was dead so I bought a new one; same result. I've also reseated the ribbon/extension cables; same result.
wat do? I'm really lost.

I'd really appreciate it if theres a solution to this. I want my x back.
How did you changed battery?
Why don't just ask support? You bought it on the grey market?
Have you seen that?

Try on an other computer to see if it's recognised

I changed the battery by taking the old one out and putting a new one in.
I already asked oneplus support, but they wanted to run a RAT on my system and I declined. Now they don't want to help me at all. Also I've already tried another computer; it still doesn't get recognised.
Are you talking aboutOPX?
The battery isn't removable.

Yes I am talking about the opx. The battery is removable if you remove the back plate.
