[Q] Hard Brick

Question, was in process of using ODIN when USB became discoed. Reconnected tried the process over but unresponsive. Decided to start over, pulled battery and now the phone won't power on. Anyone else experience anything similar or am I hard bricked to anyone's knowledge?

How much charge did the battery have when you started this process?

90% or so. Been charging it on the wall charger for the last 2 hrs but it's still not turning on.

Even though your screen Wont turn on sometimes Odin will still recognize it. Try this: turn Odin on pull battery from phone hold down volume buttons plug USB in put battery back in. see if Odin sees the phone. You may need to try several times.

It was just another example of my noobness. I didn't bother to try download mode. I forgot + and - with usb, so phone came on right into download. Only thing was Odin would not recognize phone. Hiemdall would but I couldn't seem to get that working. Then I moved the USB cable to different port on PC and ta da! Odin recognized the phone and the rest is history. Finally rocking the latest Valhalla.
Thanks again everyone.

That's great. These phones are very hard to brick!

OK, so I don't have to start a new thread and waste space (on the internet?), I wanted to try and piggy-back off of this one; feel free to move it.
Basically, I thought it would be OK to flash a Vibrant ROM over my girlfriend's GS4G. That was a stupid, stupid idea. I'm thinking hard brick, but cannot be sure. I've tried all sorts of button press/hold combinations, batter in/battery out, usb in/usb out and I get ZERO response.
Suggestions, or do I need to find a replacement phone and girlfriend? She works in Social Media and kind of uses her phone ALWAYS!

Well, hopefully worst case scenario you have to replace her phone. Make sure to plug the phone up to wall charger and let sit for an hour to make sure it has juice. Next, take battery out place it back in. Hold the volume up and down buttons together then plug in USB from PC to phone. This should get you into download mode. If you can get this far then there should be hope for fixing the phone.

OK, I think it was shot. We ended up going to T-Mobile, told them we did a software update via USB and the gal said, "yeah, you may have gotten a corrupt file. That'll happen." Then we got charged $20 for processing and she'll have a brand new phone by next week.
Thanks anyway.

i guess 20 isnt too bad. never flash a rom that is made specifically for your phone. dam, if you did this next week, you could have paid a little (and by a little i mean like 150. lol) and upgraded to a sgs2.

no APX device

Whenever I take out the battery, hold up and down, and plug in the cable, I get unknown device, not APX device. When I go ahead and try to point that to my APX driver, out says that it's updated. I uninstall, reboot, and try again, and get the same results.
What is going on?. Got the phone from someone, I'm guessing, botched the flash, now, I don't even have an option too switch between charging and mass storage.
Going crazy...I just want the phone back to stock do I can do it right myself

Are you using the same port you installed the drivers on, if you are then try reinstalling. Usually you have to use the same usb port for the phone to be recognized or it will show it trying to identify the device and throw up errors like your getting.
If you want the phone back to stock you can always hit up the rom for recovery thread and when followed correctly will low level flash your g2x to gb 2.3.3 ota rom.

I would, but I have no USB connection to PC at all. My phone will only charge. I don't even have to option for mass storage or charge in settings.

go to settings/applications/development and make sure android debugging is checked, then plug into pc by usb. Also did you install lg drivers for your phone?
Sent from my LG-P999 using xda premium

I did install drivers from LG. And I've.tried.with debugging on and nothing works. I believe IM also stuck on the stock recovery as well.

Check under the HDMI output protective cover and make sure there's nothing in there shorting any of the pins.
Sounds crazy, but I had the exact same problem as you, and it turned out there was a bit of metallic debris (little piece of something) rattling around under the HDMI cover that was shorting the pins. Took it out, worked great after that.

Good idea...I never would've thought about it...but alas, that isn't the problem.

so you downloaded the apx drivers, all you need to do is go to device manager and manually update the apx device so you can do the rom for recovery method.

got it....i finally got my hands on another charge/usb cable. for some reason, that was the problem. thanks for yall's ideas. though i do find it hilarious, that on two different forums, i had said that i had the drivers installed, and that the phone would ONLY charge when i plugged it into windows...everyone tells me to install the drivers.
as much as people on this site tell you to read the thread, very few people do. lol...
now i've got CWM recovery flashed, but when i try to choose to restore my stock zip, it tells me md5 mismatched

USB not mounting and computer does not detect

Ok I have drivers installed and USB debugging is off all the normal stuff and the phone beeps but storage does not show so I can mount the computer does not detect??

Go into settings wireless and networks USB utilities and toggle the setting in there.

Sounds like PC to me, happens reboot PC and phone if it does not help I would suggest plugging it into another computer. If it works then try your computer again. This happened to me before with an external hard drive. Hope you get it worked out.

This also happened to me, it was working properly before but it just stopped. It seems that the phone always detects that there is a USB connected even if there was none, evidence is it is always in the charging state when I check the battery status. I think this is a hardware problem. I'm still looking for a solution for this.

USB issues like this will never make sense to me. It's working fine and then not, back and forth. I too am looking for a resolution.

I've never UNCHECKED USB Debugging.... during Odin connections or transferring files between phone and computer. As soon as I plug USB into phone, the USB symbol appears in notification bar and then I press notification to transfer files between computer and phone. My SR internal and external storage are recognized as drive letters on the PC. Try leaving USB Debugging checked and see if that works for you.

I had this problem using my front USB port on my computer.
When I switched to the rear USB port, it worked fine.
Well... it kills my DVI KVM every time. But the PHONE works.

i highly believe this is a hardware problem because mine started when the phone overheat and turned itself off. I already tried resetting to factory setting but still the problem persisted.

good point there have been instances where I have had to switch ports to get it to work.

I remember also having the same problem with a USB cable I used with my captivate. This cable worked well with the captivate but when I plugged my Sky, I had the same problem as you. It took me a while to figure it out and change the cable.
Hope it help

Thank you.

Hey guys. I recently came across the same problem as the OP.
My phone will not detect that it is connected to a computer, and the computer will say that the device is not detected/has malfunctioned.
I have tried a factory reset, I have tried USB debugging, checking and unchecking, I have tried going into USB Storage and hitting the connect to PC button.
The phone does not connect using any of the 6 USB ports. It does not connect to my home or work computer. I have used two different cables, the stock and a third party one. (I have always used stock, never any third party until now to resolve this issue.)
This problem also came out of the blue, no changes were made. The phone is stock no rooting or flashing. Although that was the plan, but now it seems pointless.
Judging from the responses on many websites, I would have to say it's a software issue that can't be resolved. Or maybe a hardware issue. Either way I'm sending it into Rogers (Canadian carrier it originated from) tomorrow if I can't fix it by tonight.
I would love help from the outside public, but please respond with suggestions that are more intricate than to hit the connect to PC button, as I have exhausted all of those options already.
If this is a random occurrence, (and it seems like a common problem from all the results I get when searching for answers) then this phone model really needs to have a fix or something down the road soon, because this is ridiculous.
EDIT: Also tried reboot of the PC. It's Windows 7 64-bit so shouldn't need drivers either, and it was working fine last week.

If u did all that, u did ur due diligence in troubleshooting the problem. I almost guarantee ur mini-usb is dead, or maybe damaged so that it still allows charge but won't connect to computer. Send it in to Rogers, they should give u a temp phone in the mean time becuz its under warrantt

Yeah I figured something hardware related decided to crap out on me.
Is there a specific cause for this to happen? I plan on rooting and flashing different roms when I get the phone back, and don't want to have this happen again out of warranty, or else I'm screwed.
I try to take good care of my phone, so it's weird that this happened. If it is a common problem, then I guess I'd have to be careful to not do anything on my phone that's not reversible.

Replacing the usb port on some devices arent solving the issue.
For example, i have a usb bricked GT-N7000 and technician said that usb port is working on another device but there is something blocking usb mounting in the emmc. I dont have a bricked emmc, but the thing is i have been searching all over to find a fix for this thing more than a year now.

Stock Charge problems

Starting yesterday my phone boots up in Car Mode- every time. Rebooted at least 10 times, battery pull etc. Won't stop. I've never seen car mode before. Same if plugged in or not. Also at the same time the screen now rotates when auto-rotation is turned off. Checked settings in Go Launcher etc. Can't figure it out! I'm up for early upgrade and can go get a Note 2 today but am hoping this thing will make it until the S4 is out! Phone is stock- the only reason i ask questions here is that i know you guys know your stuff and i might get a fix!

And speakerphone is on by default now when taking a call.

Even though it's charging many have said it's the usb port. I'll just live with it until April. Thx!

could be the car mode app - some setting in it is telling it to launch at startup. I would try to either clear defaults for that app or download another app that enables car mode (like vlingo), and see if you can force it to ask you upon startup.
regarding the rotation - you might need to uninstall and re-install GO.

My Charge did that once. It was a bad USB port. It sucked because it also kept the USB port from being used for anything other than charging...it would not recognize it as USB.

Bad usb port. I took a tiny screwdriver and bent the the little metal plug up inside the phone. Now it functions right. Can upgrade now but patiently waiting for S4.

MT4GS Wont Turn On Help

Ok so my mytouch was charging on my computer then i went to check on a text message, the screen was black but i could see the backlight. So I assumed it was a normal glitch or something so i disconnected it and pulled out the battery, but it wont even turn on or charge now.
I did everyting
I took out the battery
I tried a different battery
I took out both the sim and the sd card
I tried to load on bootloader
I tried a wall charger
Nothing has worked!
Anybody got any ideas.

When you say "Wont even turn on or charge"...
Do you get a buzz when trying to turn on?
How long have you left it on charge?
Does your computer recognize it when plugged in?
Have you rebooted your PC since the issue started?
When you pulled the battery, did you also unplug the USB cable?

What happens if you take out the battery and while holding down volume + & - you plug into PC via USB?

I hear the noise of something being recognized on my computer but nothing on the phone. Happens with or without the battery regardless.

Have you tried any adb commands?
adb reboot bootloader
adb reboot recovery

Sounds suspiciously like hardware, maybe main flex went bad and... well actually probably not as I think it would still vibrate. If you have debugging turned on and the proper drivers in pc the you can try a screen cast and see if you have anything, that or maybe some adb commands.
Also try another pc, one that it has never been connected to, see if drivers try to install

Ok. So it's not totally dead. (It's not necessarily recoverable, but it's not a full brick.)
A failed flex cable isn't out of the realm of possibility. You mentioned you were checking a text.
Did you open the keyboard, or hit the power button or trackpad?

I Hit the trackpad i think. Once i pressed it i got an empty screen. I already tried using ADB commands but adb wont even recognize my phone once connected. I have tried refreshing the daemon servers multiple times still no detect. Its like out of no where i decided to die or something lol
