my T-Mobile LGP999DW wont even turn on - General Topics

im a noob any1 no how to fix this problem?

some basic troubleshooting. Pull the battery out for a minute or two, put it back in, try to turn it on. alternatively, make sure the battery is not shot, plug phone into charger and try to turn on while charging.

na its none of that I had rooted it with superoneclick then ssomething went wrong it said invalid sim so i looked into the baseband neways i ended up flashing stock it worked till i powered down after that i never powered back up now i cant even get it in software upgrade mode ? any thoughts

Fastboot with a PC connection perhaps? It's a way to install packages/images from PC. familiar? I am not knowledgeable in it, Ive only done it a few times, but there is tons about it in the forums.

For the lgp999, it has tegra, so a different method to root is required. You have to have nflash or something of the like. At least this was the case when I rooted mine 2 weeks ago. Check it out on the forums.

[Q] Display going bad on my Infuse 4G

Hi to all this morning,
I spoke to the local AT&T manager about my phone. The lock screen numbers and letters are "burned" on to my screen. Every time I go to a "light backround, I can see the month, time and "phone locked". The manager told me to call AT&T service. I called the 800 number and was told I have to do a "hard reset" on my phone for the warranty procedure. I have an "unlocked", "rooted" phone. Will a hard reset unroot and lock my phone?
Do I have to "unroot" and "lock" my phone before calling them back?
Any help would be greatly appreciated.
Kind Regards,
Jim
Before u return the phone to store, I would strongly recommend restoring to how it was when you got it (stock).
How do lock and unroot?

Look for gtg back to stock or h8's back to stock. They both utilize Odin. Just read the op and you should be fine. Let me know if I can help.

I do need your help. I downloaded the app you suggested and tried several times to use it. Here is my problem.
My computer connects via usb for mass storage an media on com port 9
I have downloaded all the latest usb drivers for Windows Visa. When I use the procedure suggested by gtg, the com port does not show up in the Comm ID box. I have tried and re-tried several time with the same result.
Can you help??
My display is getting worse every day.
Thanks,
Jim

I assume that you are using http://forum.xda-developers.com/showthread.php?t=1116251 one.
I had to use this a whole bunch of times when I just started flashing and though it worked really well the first time after that it started to not work as well. Switch your USB ports that you plug your phone into. This will make it show up in a different are other than just COMM 9. If you cannot get it to work in any USB try a different computer, leave it sitting there for a long time. I don't think that it really had anything to do with my eventual sucess but after just leaving the battery out and the cord plugged into nothing made it work. Just telling you my experience. I hope that you are able to figure out what is wrong and flash back to stock before your screen gets any worse!
So you tried to odin back to stock and it doesn't work?

More questions,
It did not seem like it wiped everything off. auto reboot was checked and fast reset was checked.
first block on top left is green and says passed time 4.49
Just wanted to says thanks. I plugged the phone into my laptop and it worked. Now I am fighting with AT&T to get it returned. They seem to think a display hardware issue is a software/virus issue. Thanks I got it to work with your help!!
Kind Regards,
Jim

No problem. Glad that I could help. And do push the issue. Right to the manager if they still won't take it. Or you could try calling them and eventually you will find one rep who is willing to push it through. Either they will be dumb and don't know what they are doing or they will know where you are coming from and help get it returned. If not, and you are still under warranty you might be able to send it back to Samsung and see what they will do about it. Good luck!
i believe if its under 30 days they take it back on the spot and exchange it for you.. if not they might ask you if you have insurance on you phone and send it out to a authorized ATT repair store... just my expierience...

[Q] Phone is DEAD!

My phone will not switch on. The battery is fully charged, i checked it with a reliable voltmeter and it read 3.7 volts. I put a different working battery from a different working sensation and still nothing. The led does not come on when i connect it to the charger and i am losing patience.
The back story is, yesterday i flashed SENSEay onto my phone and all was good. I used titanium to restore the apps, no data, I made a backup and left the phone alone for a while. I decided later on that i was going to play a game of samurai vengeance, but to do so i had to install chainfire3d. I did this and tried to install the beta part of chainfire, unfortunately this caused a bootloop. I pulled the battery and went into recovery to restore, restore went fine and my phone was back to working. Before i went to bed i put my phone on charge and when i woke this morning the bugger would not switch on. Because it has happened during the night i have no idea what occurred to kill it, all i do know is that no-one else has played with it. What the hell has happened to my phone?
All help will be gratefully accepted.
Your in the same boat as me buddy
I started going through the same issue yesterday, finally gave up and called HTC. Your phone (like mine) should still be under factory warranty with HTc so they are willing to fix it for free. I am gonna send mine in but am hesitant because idk if they will be able to tell if its rooted or not.
I have no idea if they will be able to tell if its rooted. What have you tried to get your phone to power on? Most threads with similar problems seem to be battery related, but thats not the case with my phone.

bricked phone?

okay so i think i bricked my phone. its very strange like my usb got turned off but i have only installed infuse 4g roms so i have no clue how that could happen
anyways it will boot to the samsung logo and nothing else. even with a jig i made and tested on my friends nexus s (and every button combo for download/recovery)
any ideas? before i tried to reflash i was getting some weird problems like my phone would charge in sperts as if i was continuously pluging and unplugging the device. and i couldnt use the usb to transfer files

Skyrocket usb error

Hi everyone, this is my first post requesting help.
My skyrocket charges with the usb port but wont connect. I tried a darkside wipe, format of system data cache emmc and reflashing many roms. I want to use odin and try to use stock.recovery and rom to see if it works. I enter download mode and it still wont connect. I reinstalled kies and still doesnt work. Its not my computer cause my t989 galaxy s2 connects and these two phones are nearly identical.
Running ics real thing 4.2 v9 cwm touch by realsk8tr
If possible, try another computer.
I have the same problem with mine. This is a new problem that just started a couple weeks ago. Mine seems to be a hardware problem since it won't recognize USB connection in CWM, Odin, the stock rom, or my current Sky ICS rom.
I'll flash back to stock and send it back for warranty repair once I get another phone to use. I have a contract renewal coming up in May, so I'll do something then (I bought this one off contract, so I have to send it to Samsung)
Its a real pain because I have to transfer everything wirelessly between to/from my laptop.

It is a new problem that occured after using the ics leak. I cant believe there isnt a solution. Can you link me to a zip method that will return me to stock GB without the use of odin? And can i send my skyrocket in for warranty replacement? I never got insurance on it, i brought it in november from att nyc. This skyrocket also gets dev/block errors upon format. Any ideas guys?

What radios have you flashed? Also did the problem just happen after a flash or appear out of nowhere?
Just for the heck of it try uninstalling kies, the drivers should stick. Sometimes that'll do the trick

Mine happened while I was still stock/rooted. I had changed nothing for several weeks. It just stopped recognizing when it was connected to USB. I have tested on multiple computers and tested another sgs2 on my laptop. The problem is definitely with my phone. No other computers recognize my phone is connected, phone won't mount USB, etc. Yet other phones work fine when connecting to my laptop.
I even flashed back to stock GB 2.3.5 , etc. Its not an ICS issue since this happened prior to flashing ICS (it actually went tits up in March prior to the leak).
I have a GB 2.3.5 Nandroid backup I'll flash before sending it to Samsung.
Samsung warranty is good for one year. AT&T will only do a 30 day exchange type warranty. Anything after 30 days has to go back to Samsung repair.
My only concern is without a USB connection I can't flash to the stock recovery. I can flash to stock GB and unroot and clean it up on the ROM side, but it will still have CWM recovery. Oh well.
The way I see it this is definitely a hardware issue. Samsung should fix the hardware problem regardless of the recovery software.

I guess I should have stated I have tried about 6 different cords.... I am a Systems Admin, so I've tried all the obvious fixes. It just absolutely will not recognize a USB connection anymore. Also, none of the computers recognize that a USB device has been connected.
It's definitely something wrong with the USB on the device.

you're gonna have to send it to Samsung for repair then.
I did flash the note modem once maybe my efs is corrupt
No, it's not that. It's hardware. It's almost certainly a cold solder joint. Must be a bad batch of I727s out there, mine's doing the same thing.
Sunday, I had a 30 minute call. After, I noticed the phone would charge, but couldn't get the computer to see it as a USB device. Last night, after an hour long call, I tried it and it worked. Managed to get it into download mode, flashed the stock .tar with ODIN, and got back to stock. About five minutes after that it started failing again (charging but not connecting, etc).
I'm using my T989 as a charger. If you can find a way to charge the battery, what I'm testing now might work. [EDIT: I re-read the OP and you have a T989 as well so you're set!] I'll post back. I set up a call to a test number (909-390-1390 is a 1Khz continuous tone) and placed the phone on the back of my video card with the USB cable connected. If it connects, we'll know this works for heating the phone up enough to temporarily 'fix' the cold solder joint.
But my skyrocket charges perfectly, via wall charger and usb, i have no need to use a external charger
You may not have the same issue as I have. I will note that as mine degrades it'll start acting as though I'm repeatedly unplugging it (PC rapidly going through USB connect/disconnect cycles, etc), then it'll still show that it's charging although the PC no longer recognizes it, until finally it acts as though the USB does nothing at all. The hotter I get the phone, the longer each stage takes.
Im just concerned that cwm will bone you from Samsung. one crazy idea is force brick so it doesn't turn on at all if they can't see recovery then you can anyways claim power failure

This is a good thread. My skyrocket is a used one from Texas. Won it on Ebay. Shipped out quick. Nice unit except it did exactly what I see described here.
It worked great the first day as a stock ice cream sandwich or whatever you call the ATT skyrocket software package Android 4.0 something. The USB hookup started getting flaky the more I used it, it would disconnect. It was unhooking, and I'd click to "copy files to PC" button again and again. It made rooting it a real challenge.
As if getting your arms around "Odin" wasn't intimidating enough...
I thought it might be from being jiggled, so when I was stashing the last of my downloads to flash CM9, I was careful to have it on a surface when I gently touched the screen and got all the files copied I wanted, and the phone, computer, and data cord left untouched, appeared to "work" ahead of the epic fail.
After I flashed the new CM9 from (wow thanks team chopsticks!) the USB is not recognized either in the skyrocket nor the computer, nothing. It shows charge, that's it.
I intend to get a USB reader for the microchip as a work-around. The phone screams. This is my second skyrocket and the new CyanogenMod 9 is the love I've been looking for. At last, a phone that can bring up a gallery full. My first skyrocket had trouble when the 32 GB microchip approached full. This one flips the 20 GB worth of pages full of folders up like nothing flat.
Also, interesting detail on this used Ebay phone... the first thing I noticed is you can't power it off. The seller shipped it with the battery removed. I tried plugging it in, leaving it unplugged, this i727 just will not power down. I do love the touchwiz recovery, and how you can select to reboot and then choose to boot into recovery. That part worked nicely and I am over all happy.
I know its late replay but I got solution!
I had same prob all i did was took toothpick stick it inside phone USB connector thing and pushed it little bit up and now it works perfectly FINE!
Yes the toothpick fix does work. Had the same problem with mine. Read about using the toothpick to fix this problem from a post back in December of last year. Don't pry up too much and break the toothpick off inside. A little twist is all it needed on mine. Noticed some dirt and grime came off on the toothpick. Maybe this helped clean it as well

Phone wont turn on help!!

Hey guys. I'd really appreciate your help. So this is how the story goes. Im pretty well versed in flashing ROMS. I flashed the CM10 Rom, don't remember the exact name, but it's the one where u can download a bunch of themes. Anyway the wifi kept coming on and off so I decided to try another ROM. I went into recovery mode and flashed the MIUI vs OTTER ROM, I think thats the name, I'm pretty sure . Just as the flashing finishes the phone turns off and BAM!! The problems start so basically phone wont come on now. I don't get the vibration before it starts, so I figured Id root back to stock and start all over...(Odin..PIT etc.) So this is what happens. The computer makes the noise that indicates something's been plugged in and then immediately it makes the same noise as if somethings been unplugged (phone is still plugged in though) Screen is completely blank still and a message comes up (ON PC) to install new software on ( the phone). The software or Device that registers as the phone in device manager is Qualcomm CDMA technologies MSM. Any help would be appreciated. And yes I did the whole wipe factory/dalvik etc. right before flashing the MIUI ROM. The computer says I need to flash drive F to be able to use it (which I figure is the phone, and flashing would erase everything right?) but as I try to do that it denies me permission because th phone is apparently coming in and out, or on and off.
Have you tried a jig? Do a quick Google search "Samsung Galaxy S Blaze 4G Jig" . It'll get you into download mode and allow you to flash through Odin back to stock, I believe.

I've tried everything including:
Taking battery out for extended periods.
Trying to hold volume up button and power/vice versa with both and volume down, whilst running odin to see if Added" pops up on odin so that I can root to stock and start over."
Every time i plug the phone into PC you hear the plug and unplu sounds as if the phone is continuesly turning off and on but nothing on the screen. Im not even getting the vibration.
I had a similar issue on my phone recently. It was incredibly frustrating so I just left it on the charger. When I came back 30 minutes later, it was on and charging.

I have almost the EXACT same problem. BUT, I do have a jig that I know that works...and it doesn't bring me to Download Mode. :crying:
No button combos work...download or recovery, I don't even know if it is charging...had it on the charger for about 30 mins so far.
(It says exactly:
You need to format the disk in drive G: before you can use it.
Do you want to format it?
<Format disk> <Cancel>
I of course press cancel
With a battery or without a battery, when I connect to the computer it installs the drivers as stated above but it continues to ask if I want to format it. If I leave it plugged up, the popup continues almost endlessly. I've not yet press FORMAT, as I would think that could make it worse than it is.
Has anyone seen this type of problem?
*EDIT: I'm sending it out on Monday to get it JTAGed, too expense and complex to even think about trying to get a box and attempting the fix myself.
I was basically told that the Boot portion (whatever it's exactly called) needs to be re-written and then probably just flash stock firmware on it.
Just wanted to leave this here to help others search and find this info...just in case they attempt to try to do more than they should and really mess their phone up even more.
