[Q] Bricked LG Nitro detected as HID - LG Nitro HD

Owner said she left it charging overnight and by morning it was dead.
battery was totally drained, i used my own phone to test the battery.
lcd does not turn on, no lg download mode and not even qualcomm download mode.
the wierd part is pc detects device as usb HID. vendor id is 05C6, which is qualcomm's id and product id f006, who knows what it is.
i do have jtag tools but i want to try other options first.
keypad lights turn on when battery almost drained like all nitros do but nothing else besides that. i have tried all key pressed combinations that i could think.

I am assuming you tried your own battery in the phone and same results? If so you may have to use jtag as there is "hidden" boot loader that gives access to the DL mode and recovery partition and if that's gone the only way I know of is with a jtag device. Good luck.

Yes i did. It drained it cause i tried lots of things. Tell me more about the hidden bootloader. Im no n00b, you can go straight to the real thing. I also do this for a living and if i can contribute to the forum, its better.
I went over 4pda and found that the vid+pid are supposed to be correct but it is detected as HID instead of qcusb. I will modify or update my drivers tomorow just in case.

i wonder, if this issue could be caused by faulty connection from battery to phone, does anyone know if the battery connection is faulty would the phone still turn on when plugged in? i don't think so, try pulling the battery from your working phone, and plugging into usb, my guess is it won't turn on, if thats the case you might want to see if its possible to replace the connection, i can't remember if it looked detachable when i was replacing my ditiziger, i would check these with my phone but i have a tripple layer case on it and its a pain to take it all apart and put it back together, its something to think about tho, i only thinking along these lines because its the only explanation i can think of as to why the phone would die while plugged in, and not work with a new battery. i think it might also detect as HID if there is 0 power in the device (which could happen if it won't turn on while plugged in with no battery) if the battery connection is faulty.

let me know, i'm curious

first thing in the morning i did today was test my device with no battery through usb but nothing showed up on device manager. after that not even the bricked one was doing it but eventually it did. i also did a voltage test from microusb charger to battery pins and Vs are same as my phone which is a little less than 1v, which is really odd cause it should be over 3v at least. battery is being detected by phone because when its very low on charge, keypad lights blink a few times.

hrmn interesting, one thing ur missing is there is no way the cap lights would light up to warn you about low battery if there is 0 power in the phone which is what it sounds like, so that doesn't really mean its detecting the battery. i'm honestly not sure if im right but it still sounds possible

hello! i'm new user. niceto meet you

When i first tested the battery on my own device, i plugged the charger and it did that. Forgot to mention that its only when plugged. I had to wait a little to actually see that it was charging. Ill try the same later today just to verify that im not wrong.
edit: i just recreated the HID connection with my working phone. it seems that they do that when they are discharged or something like that. when tried the other day, did not happened at all and i took sometime.
Officially gave up. Im doing jtag.

Major problem...(phone wont charge)

My phone has started acting weird lately and im not sure why, it could just be a bad battery but im not sure until i put another one in it tomorrow. Ive been using myns 2.2 for a few weeks, and cm6 for a long time.
Myns has been setup the same way for weeks, no changes at all. Yesterday i woke up and my phone was dead, but before i went to sleep it had a little over 70% battery.
Its not my charger ives tried different usb cables, car charger, etc. The battery icon will change to charging but the % never goes up....
Any other ideas except a bad battery?
Could always do a nandroid backup, then do a wipe reinstall, just to see if its OS or app related. Then if no change was found in regards to battery drainage,you could go do a nandroid restore, if you found it was just a bad battery all along.

i did a backup and full wipe earlier when my phone still had about 30% battery. Still wont charge.
Turn your phone off, and plug it into a USB charger, see if it charges. If not, try plugging into a USB port on a laptop/desktop, while the phone's still off.
Just a shot in the dark here.

yeah ive tried to charge it every way possible lol. thanks for the suggestions though!
So your usb will power the phone enough to turn on? Can you do all adb type things like the USB is connecting right? It could always be the battery or bad contacts/solder on the phone part

Assuming you flashed new Rom correctly, you can start to look at battery and hardware.
Id start wig battery, maybe sprint store has one laying around they could pop in ling enough to observe its behavior. Maybe buy heap battery from ebay.
I m not the authority on anything but I would flash back to stock and ask Sprint store to help you out. If you walk in with custom Rom they may flag you. I find it hard to believe you have a bad battery already, but I have seen stranger things.
How long does it take to charge? And precisely how long it last? An hour? 30mins?
Oh my bad, I see its not charging at all. Could be bad cable. Bad thing is, if they find that he usb port is damaged they may not warranty that. But who knows.

USB wont disconnect.

Hi I just got a e4gt used from a coworker for 80 bucks. But I'm having issues with it. Even off the cord, it says mtp connection. Every time I turn off the phone it sometimes starts right back up again on its own, and sometimes shows that it is charging, again while it is off the cord. Anyone have this problem? Since I got it used can I still take it to a sprint store and have them fix it? Thanks.
Its really annoying. I want to root it before I switch my service over since I want wifi tethering.
Sent from my PG06100 using XDA
I have had this problem before. Once with my launch day e4gt and twice my current e4gt. The first one, I took to a corporate store and they replaced. The two times with this phone, I took a wooden tooth pick and cleaned the USB port (with the battery out). So far for me, that had remedied the problem.

Use another USB cable
I tried a different cable, same thing. Even when I connect a cable to the phone but not the computer, it thinks its connected. Starting to think I have a bad USB port or something. Since its used, do I have a manufacturers watlrranty or something?

If you have TEP, it would be free replacement at a sprint store. If you don't, it would be $35. We don't care about devices be used, per say.
However, this is all assuming there isn't corrosion in the charging port, which will generally cause the issues you are having. Take a peek in there with a small light and see if you can see any white cloudiness or rust.
Sent from my SPH-D710 using xda premium
What is TEP? Does the warranty carry over of im not the one who originally bought the device? The guy bought it in september i think.
Sent from my SPH-D710 using XDA
It sounds like liquid damage to me.
Look really closely inside your charging port for anything green/white, especially toward the very base of the pins. Also, look at the charger itself for any green/corrosion on the pins. If you find any, dip a toothbrush in some denatured alcohol and scrub your charging port.
Works like a charm.
Ok so after cleaning out the charger it seems to charge better, but it has a different problem too. It doesnt stay off. Every time i try to power down it automatically turns itself back on. I want to root this phone before i switch my service over. Is it safe to root this phone if it doesnt turn off and stay off? And would a coroded charger port be the cause of it turning itself back on?

Make sure the device is usable first. A corroded charging port could definitely help in bricking the device, by not completing a full flash during installation of software.

hi all,
n00b here so go easy !
im having similar issues to the OP, with the phone constantly telling me that charging has been paused , voltage too high , even when the phone is not charging.
my phone has just been returned to me from a warranty repair for a faulty button and camera , it took almost 2 months to have it repaired by samsung.
i really cant face not having my phone for another 2 months if it needs to go for repair again.
how much would it cost to have the usb replaced on the phone if i was to bring it to a standard phone shop ??
thanks in advance guys.
p.s. i wouldnt risk trying to D.I.Y. it as im really not good at that kinda stuff.

That's very odd. I've seen liquid damage cause the phone to stay powered on constantly, but normally doesn't have anything to do with the charging port.
Pull your battery and leave it out for a few hours to fully reset the internal battery and see if that does the trick.
Did you use Denatured or Isopropyl alcohol to clean out the port? If not, you may have damaged something.. It doesn't take a whole lot of alcohol to clean out the port, just a dip into the alcohol with a toothbrush and a lot of scrubbing.
Regarding this being a widespread issue, I don't know if the port is more susceptible to liquid, but I have seen this issue four times over the last month and a half.. (Mainly with the Galaxy Nexus) Cleaning the charging port has resolved it 100% of the time for me and I have not heard back from anyone saying the issue returned.
OK so for some reason the charging works and the phone is able to shut off. Now I have a new problem. My e4gt will charge when plugged into the pc, but the pc doesn't recognize it. I want to root my device, but the computer will not recognize it no matter what! I tried uninstalling the drivers, reformatting my phone / sd card, restarting the computer, reinstalling the drivers, and i just can't get the computer to see the phone. What can I do? This is driving me insane.

my xperia s isnt doing anything

My phone died last night because i forgot to put it on the charger before i went to sleep. The problem now is that it just wont charge anymore. I have left it on the wall charger all day but i just dont get the red light. I flashed a custom kernel, maybe that has something to do with it, but it has ran out of battery before so thats really strange.
Any thoughts on what to do? Really clueless here guys..
Just let it charge

What kernel? Can you connect the phone in fastboot/flashmode?

Try hard reseting it
Sent from my LT26i using xda premium
Yes, i did try hard resetting it but it gives just no response. Havent tried booting it in fastboot tho because im not home now.
Im running the kernel from the free experia project.
How screwed am i?
i'm not so sure but this is occured to me on my XAS .200 after flashing custom kernel not too long ago. but this is happen when i use custom kernel on XAS.
it will not charge, and fortunately fellow member here warned before it's too late and managed to reflash stock kernel before running out of battery.
i'm not sure about XS's battery whether it can be removed or not, but if any way to do it, you need to recharge that battery/replace the battery with fully charged one, and reflash to stock kernel.
again, this is from my experience with XAS though. i just thought it could be the same.
the same happened to me. I open the phone, removed the battery, conected the charger, and put back the battery. After that I got the red led and it charged. And yes, I voided the warranty.
Try connect it to USB port! I've had the same problem. I don't know why but it will only charge through USB cable connected to PC. Leave it for a while, u'll be able to turn on your phone.
Sent from my LT26i using xda premium
You should be able to get the phone into fastboot mode, once you are home that is. Im using FXP kernel too and have had no issues so far. Try flashing the kernel again maybe.
Some kernels have problem with offline charging (they won't charge if phone is turned off). It is possible you flashed that kernel and because of that it won't charge. Only solution is to replace battery with full one and then change kernel, like member before me mentioned.

The problem is, I can't remove the battery with this model, it's embedded in the phone like an iphone. Also, I can't get it into fastboot or flashmode... as I can't really do anything with the phone right now it might be best to just bring it to a repair service...

I know battery is non replacable (without voiding warranty) but still there are ways to replace it
But it doesn't matter, bring your device to a service and hope they will bring it to life again.
Well I know this idea sounds stupid but I try it on my Xperia S when my phone gets hanged or when the screen is totally black like its dead. I just press the power button and volume button simultaneously for some seconds. And after that my phone gets restart. I'm already telling you that I use this method on my phone and it works too.
Thanks

You CAN remove battery, just not the normal way. You have to remove the screws, that's why you will have to void the warranty

Unresponsive Phone

I bought my Mom a used Inc2 on eBay. Rooted/S-OFF running SlimRom 4.2.2 on Page Plus.
My Mom messages me on Facebook to tell me she thinks the phone is broken. I have to agree. I don't know what she did, but she seems to think she had somehow got the phone into fastboot/bootloader/recovery and was trying to pull the battery to get it back to normal. She thinks she selected something before the battery pull, but doesn't know what.
Phone won't turn on (no splash screen, no boot animation, no nothing).
No LED when phone is plugged in.
Tried several charging cables.
Tried switching with a battery known to work and be charged.
Nothing.
Anyone else ever have a similar issue? Is there any way to repair this (taking apart phone and replacing parts)? Or should I just buy her a new phone?
Pull the battery completely..wait a sec with your finger on the power to completely discharge it ...pop battery back in volumedown +power to get into recovery check to see if she formated anything fix w.e profit perhaps ?

Battery is my guess
My guess was the battery too. Your mom may not have put it back in correctly (My mom sometimes can't see the little gold connectors without her glasses.) Make sure the connectors match up.
If that wasn't the problem, try using a (cell phone) universal battery charger.
(Amazon.com has them for cheap, and they save your life if your usb port ever dies until you can replace the charging port.)
Once you know the battery is charged, and put in correctly, you can tell if it's the phone or not.
If she wiped the system cache, you won't boot. But, you can always try placing a new ROM on the SD card (easiest way is using a desktop computer with an SD card reader,) and re-install the phone's operating system (rom).
Even if the phone is somehow bricked: you can still get her data and pictures off the SD card with any SD card reader connected to a computer.

Thanks for the responses. But alas, it is not a simple matter of battery wrong way. My gf has the same phone and hers works. I tried switching batteries and the one from my Mom's phone works and has about 40% juice in it.
But her phone won't respond at all. When you plug in the USB charger, the LED should come on to signify that the phone is receiving power from the wall/computer/etc... There's nothing.
The phone doesn't turn on at all. I can't get into recovery because it won't power on at all.
She said the phone booted a couple times before I got it, but got stuck on the boot animation and never made it into the actual ROM. Now it won't come on at all. I guess the phone is bricked completely (by no fault of the software - I think this is some sort of hardward issue but I just don't know what)
I guess I'll activate her old phone. Thanks for trying to help.
(I really thought holding the power button without battery in might work because I had used that trick once before, but alas, nothing)
Maybe the power button is dirty try to clean it there's I tear down guide...you won't need to go far into it tho verrrry simple...voids warranty for sure

I have same problem and when i got maintenance center they told me must change the IC flash for phone :crying:
Check the USB port
These phones came out so long ago I imagine original warranty is long gone. I that's the case, might as well open it up and check or fix the power button like chilly suggests.
There are little ribbon cables everywhere inside, for things like the USB port, screen digitizer...and if the phone was dropped, it could have squished the power button, and easily, jarred a ribbon loose. Checking them all out and inspecting the power button might be all you need to do for a fix. At the end of it all, even if nothing is solved, you can sell the phone for parts on ebay and make at least $45.
I thought about doing that once, but I'm glad I inspected mine before I hit the "sell button." I watched some tear-down videos on youtube and decided to give it a go. Now I'm much more comfortable with tinkering with phones. It can be a nice learning experience.
It started when I once tried to plug in my phone in the dark, and I actually managed to cram the USB charger into the phone upside-down!
What this did was make the phone un-chargable, even though the usb cable would still fit in there just fine.
Same symptoms you are having: cord goes in, no light comes on. Yet, the cord charges other phones just fine.
On ebay you can buy new USB ports for about $6-9. I purchased one, found a how-to video on youtube, and repaired mine myself with just a cheap torc x screwdriver set that I purchased for $8.
Fix worked 100%. Don't give up just yet.
