help did I brick my phone?

All,
I have a big problem. When I try to start my phone I get the black screen with google and the unlocked padloack, after which the screen goes dark and nothing happens anymore.
What I did before this are two things. I had been mukking around with the screen resolution (I had it set at 240 and 280, as some apps did not show up in the market) also downloaded LCD density to solve the market issue.
I then rebooted the device and entered CWM to do a backup which as far as I knew succeeded. unfortunately after rebooting, see the above.
I have tried a couple of reboots, tried restoring the nandroid (the above was the only one I had). that didn't work, so tried to connect to the PC to load a new ICS rom (original 4.0.4 by google), unfortunately my device can not go into USB mode in CMW (it comes up with UMS lunfile missing....)
so I am woring in circles. can't start the device to download a rom, can't open USM to load a ROM to start the device again.....
any help would be appriciated
thanks
Patrick

hey
flash a new ROM via fastboot then, there are enough guides
-Syn
Edit: Alternatively, flash the stock Google ROM via GNex toolkit and go from scratch.

as mentioned, I can't get a rom on the phone so that I can flash it.
I can't start the phone to donwload one, and can't connect it to usb to get one on the storage....
sorry, you mentioned fastboot.... not USB.
so connect it to usb cable. I then entered fastboot devices, no number came up, as was also the case with ADB. thinkin I might not have the correct USB drivers for my windows machine. any idea where to get teh correct one?

To flash stock images the files are on your PC, not the phone.
If you can get the phone to boot into fastboot (via vol up + vol dn + power) and get your PC to recognize it you're good to go.

thats the issue. pc cannot recognize the phone, so cannot get any files from the PC to the phone (ie. cannot get a rom file to the phone...)

Either directly from Samsung or download the GNex Toolkit (You might want to use it anyways to flash the stock image), the drivers come with it.
After you installed the drivers and have you phone plugged in, go to the device manager to check if it is connected properly.

For the drivers, I would recommend you remove all old drivers and install these. If you don't know how to install them, or are having issues, look here.

I had a similar issue with regard to my PC recognizing the drivers. I googled around and found that people were having success with installing the PdaNet drivers, so maybe you can try that too. I had installed the Android SDK as well as the PdaNet drivers, and I eventually got mine to work.
I would probably follow Efrant's links first though - if that doesn't work for you, then maybe you can try PdaNet drivers and/or installing the SDK.
Good luck.

Why not just do a factory reset from within recovery?
¢ £®0π π€XU$ |||

the factory reset didn't help, the phone just wouldn't go past the black lockscreen. So in the end I used the galaxy nexus toolkit. installed the drivers for the PC, was able to go through fastboot and push files and flash a new rom.
Al is now solved, just need to do a lot of work to bring the phone back to where it was and make a backup asap.
thansk all for the help!

[Q] Phone no longer gets recognized as USB storage on PC

I've tried this on both my work PC and my home PC. When I plug the phone in, it makes the familiar connection sound and will start to charge but the computer doesn't ask me if I want to open it up for USB browsing. This is recent and there have been no firmware changes. I've rebooted the computers and the phone but nothing seems to matter. Has anyone else encountered this issue?

do you have developer options (in settings) on or off? Has the usb cable been roughly removed from the phone lately. it may be damaged?

developer options are off, I've also tried several cables

Are you rooted and on a custom Rom?

It doesn't mount as a USB drive, it mounts as a media device because it uses MTP. That's not an issue with the phone, it has to do with how Samsung set it up.

that makes sense now but i cant not transfer any files to the card or the phone.

Do what the poster above me said, then make sure to unlock your phone after plugging it in or else your files won't show up

Its the same thing i can't transfer files to the phone or the external card.I don't get it i never had a problem with my galaxy 2.I've uninstalled the drives installed them again and used different cables.

i have the same problem too. my phone nolonger shows up as a storage device on my pc. i have developer options on and usb debugging checked. ive tried different cables , different computer , tried rebooting phone, tried reinstalling the drivers too .. nothing seems to fix this issue... earlier today it was working fine .. when i plug it in it pops up samsung modem and thats it.. please help

This is very strange, as a work around you can use Wireless Transfer. I've used this as my main method since my OG Epic.

same issue trying the fixes mentioned. after reinstalling the driver i get about 3 files transferred then it pops up with that error....WTH is goin on i have several gigs of books and music how am i supposed to get them off?
---------- Post added at 07:10 PM ---------- Previous post was at 06:50 PM ----------
THis is complete crap! why is this goin on?! I can get my pc to recognize the device i can browse directories but it suddenly tries to decide when to quit when i try to transfer files. I can only get about 5 folders moved before it thinks thats all and just stops it no longer comes up with the device not functioning error message anymore.......please somebody help. I dont have a large enough sd card to just transfer. Ive searched on google and there are not actually explanation only that you cant mount the internal storage as mass storage.....samsung is going the way of HTC for me. Stupid oversights renders the device a complete waste to me. !!!!!!!!!!!!!!!!

Ok last one. I was considering getting the note 8.0, is this something that all of their devices are gonna suffer from?

I'm not going to pretend to know what's wrong with your device, as I have 2 Galaxy S3 and a Gnex and 2 Epics which all connect just fine and I can transfer any and all files from the desktop or laptop no issues.
But I will suggest maybe you set up a drop box and you can share all those files from your phone to computer or visa versa.

well after a couple deep breaths i went ahead and did that after posting those. I still cant locate a reason why it would come up with that error. There are a couple posts in another forum talking about it being win7 related and not the device it self. Ive tested other cables, rebooted pc/device, checked/reinstalled drivers, and nothing come up out of the ordinary. I hope someone locates the issues, just for having an answer to this headache. thx

An answer-
For those who are having issues insure that your device is on a Stock TouchWiz ROM.
MAKE SURE DEVICE IS UNPLUGGED THIS ENTIRE PROCESS.
1.
= Go to the Dialpad.
= Enter this code ##3424#
= Menu will pop up click Qualcomm USB Settings.
= Click the 2nd Option MTP+ADB
= Press Save
Done
2.
= On your computer go to Control Panel Click Category for the viewing style.
= You will see Uninstall A Program. Click that and go to S- Uninstall Everything Samsung.
= Plug your device back in and let default drivers install takes average 45-60 seconds.
= Device detected as MTP. You may now transfer files.
Done
Let me know if this worked for you.

Ok i tried that and when i plugged the phone back in to install the drivers,they all installed except the CDC serial it says no driver found.I need help please.

do you have any other phone drivers installed on your PC?

As you said, the CDC serial (Unknown Device) popped up. Unplug your device and install drivers.
http://www.samsung.com/us/support/owners/product/SPH-D710
Click "Download" tab at the bottom and press the "EXE" button to download.
-Plug your phone back in afterwards and keep "Device Manager" open you will see the CDC Device disappear.
-When its installing I recommend keeping the "Installing Drivers" window open to see when everything is finished.
-After that's done switch phone to PTP via the notification menu. Let it load drivers and it will install as a camera.
-Switch back and MTP should be working.
Let me know how it goes.

Well it finally worked.Thank you so much did what you said and i can transfer files over to the card and phone.Again thanks for your help.I never had trouble with with the original epic and epic touch.

Did I "brick" or damage the device somehow?

Howdy y'all,
So I was rooting and flashing and when I tried to flash after successfully rooting the device, I went to wipe everything in TWRP and then flash another ROM. Well, something happened and it gave me an error saying it could not wipe (I think it was OTG something something, it's been 2 weeks now since I did this), and now it won't allow me to transfer ANYTHING from the computer to the device. It will not allow me to create folders, nothing. I have uninstalled the drivers, installed the drivers and tried SO many drivers. Anyone able to provide me a suggestion? The odd thing is on the device itself, I can create folders and everything, but when it connects, eventually, I can open the device from my computer, BUT when I attempt to create a folder, the PC gives me an error dialog saying that the device is not there anymore.
Any help would be greatly appreciated!
Thanks!

Have you tried using ADB push to get a new rom onto the device? Also I'd do a permission repair
Edit: As a side note, I don't think it's possible that you did actual damage to your device. It's probably just the software that's messed up. If you want a sure way to fix it, try downloading and flashing the stock factory image.

Bootloadeer wouldn't help and neither would ROM as this problem has to do with /data

Have you rebooted your PC?
Have you reconfirmed you are using mtp rather than ptp?
Does your /sdcard show more directories than dcim and pictures when viewed in adb shell?

That's your problem right there. PTP mode is camera mode, so you only get access to a couple of directories. Switch to MTP mode (menu under Settings / Storage).

I've tried MTP mode before and I get nothing. In fact the computer doesn't recognize the tablet is there. It's odd b/c I have done EVERYTHING I can think of and read about to install drivers (multiple kinds, like PDA, android, RAW, etc) and uninstall drivers. It sounds like a driver issue but I don't think it is.
EDIT: ok so after switching to MTP mode on the tablet, I went to device manager and uninstalled the "portable ADP drivers" as some people were saying they had issues that were similar to mine (but not exactly) here (http://forum.xda-developers.com/showthread.php?t=2380978&page=1).
After doing so, I unplugged and re-plugged the N7 back in and had it re-install the drivers from the Google USB drivers that I downloaded onto my desktop. That allowed me to get it to work and access the internal SD card on the device. BUT, when I go back into the PTP mode (camera) mode, I still have the same issue where I cannot creat subdirectories, transfer anything to the device AND I cannot see any directories except for DCIM and pictures. Really weird. Both modes obviously worked before I rooted it. Now that I have unrooted and gone back to bare bone stock I am still not getting it to work.

That is how ptp mode is supposed to work.
That is why people prefer mtp mode.

Like I said, that's what you get in PTP mode. You are able to write to those 2 directories though (not the root directory).

No way. PTP mode is restricted on purpose. Here is the commit:

Thanks guys. I appreciate all the continued help and patience. Now that I went back and thought about it, I was only transferring images WHEN it was working before. It is all good now that my silly drivers were all sorted out. Really odd how the drivers just took a crap on me like that. Weird. All is well now though and I can get back to studying my PDF's for school.
Thanks again y'all!

Hard Bricked LG E980 USB device not recognised

My LG E980 is bricked. I can access download mode and that is it! I am unable to boot into recovery,
and the hard reset screen simply sits there forever. My computer only recognizes my device as an "unknown usb device."
I'm unsure what can be done about this, but I feel like this is better than the infamous QHSUB icon displayed when the device cannot be recovered.
Does anyone have a remedy for this problem?? I have GOT to fix this phone and can't afford to Jtag the device, but I'm losing hope that this is possible, PLEASE help. :crying:

Have you installed the LG drivers for your pc and tried the unbrick method?

Yeah dude there's an unbrick method. If this doesn't work just sell the phone on Ebay. http://forum.xda-developers.com/showthread.php?t=2302660

There is never a time when this device cant be recovered. even the qhusb is a fairly simple fix. ill go ahead and make a sdcard boot image tonight. do you have a 32gb sdcard? (or larger) and an sdcard reader, if you have those two things i can make an unbrick.img that you flash toi the sdcard and put in the non-booting phone and it will get you to download mode/recovery mode. ill have to check out what partitions are where as i dont wish to include my efs along with it all .

Happened to me.
1. With the phone on download mode and plugged in the computer; uninstall the unknown device on your computer using device manager. The computer should try to get the drivers for your phone.
2. If it doesn't. Repeat step one and install the drivers first.
That worked for me hopefully I'll work for you.

I do have a 16gb sd card, but I can pick up at 32 gb sd at my local best buy. I have an Asus laptop running windows 8 and it has an SD card reader. I am a little confused (semi-noob) as to how this will work because my phone will boot up, and the led changes colors on the home button for about 4 seconds and then the light stops flashing. The phone is stuck on the LG boot screen, and there is no way out of it but to pull the battery or to reset with power button. Of course no recovery as previously mentioned. I really just want to get back to stock, but I can't manage to get both the windows 8 computers I've tried to detect the phone in download mode. Ever since I switched to the Candykat rom 4.4 the computer wasn't able to recognize the phone, even when the phone was fully functional inside the rom.
I have tried it on my dads windows 7 laptop as well with no dice. Instaled LG drivers, uninstalled LG Drivers, uninstalled device from the Device Manager. I've done everything I could think of. I previously was in a Philz touch recovery, but every rom I tried to flash wouldn't work. I tried to flash another recovery from inside it and then the device bricked like it is now. What a head ache. If you think this method would work, I am more than willing to try it, just unfamiliar with what I need to do on my end.

Okay

I will give your method a shot, but I have done this a lot already. The only thing I can think of is I usually unplug the phone from the computer right after deleting the drivers and uninstalling in device manager. Maybe I should just leave the phone plugged in and see if the computer automatically downloads the drivers, but I don't think it will because I've tried to update the drivers before. It gives me an error code "10" and says the device has malfunction or stopped working This phone has been undetectable via USB since flashing the candykat 4.4 rom. Every computer I've tried (3) and every USB cable (3 again) has displayed it as an "unknown device"

I dont know lg's download mode, kdz, tot etc all that well. im more of a samsung guy. however qualcomm since the s4 chipset has allowed for sdcards that are properly formatted to boot the os instead of the internal emmc. here is a decent guide, just need to make teh image for this device. this will let your device boot no matter how bad it gets you are welcome to try with 16gb, the rule of thumb i know of is as big as teh emmc is use that same size or larger sdcard, however some people have had sucess withs maller, just not many that i know of. http://forum.xda-developers.com/showthread.php?t=2439367
however afaik the only way to reflash teh bootloader partitions is via kdz/download mode so perhaps the sdcard will let you get into that mode and then you can flash, so long as you keep your sdcard like that it will boot fully, but in order ot get your sdcard back you need to repair teh files on your phone .

Thanks

Wow, that sounds awesome. I followed most of that. I access download mode on the device by pressing vol up and down simultaneously and plugging in the usb cable. I am more willing to try this, and if it works I will pay you from my paypal. I guess all I need now are those files to run to the sd card. I read the tutorial you posted for the samsung and downloaded the windows disk manager. I am eager to try this method, though it is admittedly very new to me.. If you can post those files, I will follow the instructions you give and pay you a little bit of money for your help!
I am a broke college student so it won't be much, but I really appreciate your response and information on this method with the qualcomm s4.

Here is the unbrick image. follow the guide for your platform (gunna guess windows) and write this to your sdcard after backing it up. from there you need to restore your partitions by flashing them .

Okay so I bought the 32 gb sd card. Just wrote the .img file you sent me to the sd card.
I powered on the phone and nothing happened, I got the same LG screen where the led flashes and then stops.
I followed that guide, but am I supposed to go to download mode instead of just powering on the device?
I got a little confused by the samsung jargon lol. I just want to know after I've written the unbrick.zip to the sd card
how do I get my phone to recognize the card is there? And once I am able to do that how do I "restore my partitions by flashing them?"
I do have the factory firmware set to flash through lg flashtool, but the phone can't be detected of course due to the usb issue.
Just want to say thanks for walking me through it this far, I feel like I'm close hopefully but unsure what to do next.

you wrote the image to the sdcard? i wonder if its because you still have the low level bootloaders that it may not be booting from the sdcard, normally this is done to fix qhusb errored devices. as for restoring the partitions all you would need to do is one its booted up push the unbrick image to the phone and use rooted adb shell to write it back onto your phone.

Possible hope??

I meant I used the windows tool to write the debrick.img to the sd card. But no dice, the device isn't recognised.
However! I installed a driver clean up tool and now if I plug in the device it is recognized as Android Original ADB Interface.
The LG Flashtools even says the port is ready! But I get the error code "10" "device cannot start, A request for the USB device descriptor failed."
So now I am stuck on that instead lol. This just sucks.

that sucks about the sdcard, it must be because you arent "truly" bricked. sorry i thought it would help ya :/.

What is the driver repair tool you used? I know this thread is old but I'm having the same problem. I was trying to root my E980 and now my computer wont recognize my device. The phone works perfect, its just when I plug it in to the computer it isnt recognized. How can I fix this?

+1
Just wondering if anyone's come across a solution to this besides a sledge hammer... been having the same "Code 10: Device failed to start" when in Download Mode, though Windows finds a driver fine when the phone is stuck on the LG screen... doesn't help much, though, 'cause it won't receive adb commands. I manually installed the LG USB Composite Device driver, which added a modem and a COM port, both of which Windows recognized to be active, but the LG FlashTool USB Viewer showed no open pipes. I'm a relative noob, so please feel free to point out the obvious, like an alternative to adb that the phone can always receive or a way to brick it the rest of the way so the MicroSD trick will work.

I came across this problem like the OP and just wanna let everyone know that you have to use computer with USB 2.0 port then the driver issue would be fixed.

[Q] Wiped everything with TWRP 2.8.4.0, now softbricked?

So just as the title says, but here's a little back story (might help).
I'm trying to help out a friend with his Bell Mobility i747M. He wanted to try out Lollipop, so I looked into it and said I could do it. Last I even touched his phone was quite a while ago when he wanted me to flash CM11, back when KK was still pretty new. So it's been over a year. I flashed CWM back then, got the ROM installed, and everything has been good ever since. Fast forward to now, and he wants to try Lollipop. I figured the first thing I should do is update the bootloader/radio, which went perfectly fine (after some researching, I chose 4.3/MK5 for his i747M). I tested them by booting back to the ROM and checking About Phone - everything was good. So I booted back to the old version of CWM, and thought it would be a good idea to get a more modern recovery. CWM or TWRP didn't matter, just as long as it was more up to date (I thought it might help with Lollipop compatibility). So I decided on TWRP, and I got the latest version (2.8.4.0 as of now) and flashed it. Successfully flashed, then rebooted recovery. TWRP is there and working. Great. Next step... I had the Lollipop ROM and Gapps already downloaded and ready to go, so in TWRP, I proceeded to wipe everything (system, data, cache, internal sd).
Uh oh... Half way through wiping, the phone reboots itself! Now there's no ROM, so naturally it has nothing to boot to. Try going back to TWRP, and I see the splash screen again. OK, false alarm... Well, not really... Because now it just reboots itself after the splash screen, every time. Can't get into TWRP no matter what! I can access download mode, but Odin doesn't recognize the phone. Yes, I have the drivers. In fact, the device isn't detected by Windows at all.
So here we are. Download mode boots, but Odin doesn't work because there's no communication through USB at all. There's no ROM on the phone because it was wiped. And TWRP won't boot beyond the splash screen.... Now what?? I tried the 80MB MK5 debricking .img on a 64GB microSD. It does nothing - besides, USB isn't reading anyway, so it's not like I can proceed with Odin.
I'm at a stalemate here... Any suggestions?
My friend's gonna kill me if I killed his phone I'm pretty experienced with several devices, but not much with Samsung. I've never seen anything like this happen before...

When connecting to the computer, have you tried different USB 2.0 ports and USB cables? Have you tried different computers? Different operating systems?
Is the phone recognized using adb or fastboot commands?

Yeah, I figured that would be the case. Just about done downloading Ubuntu which I'll boot from USB. I'll post back with results once that's ready. I should have it booted within 10 minutes. Once I get there and verify the phone connects, what would be my next step? Should I try flashing stock 4.3 first?

I would confirm the bootloader that is on the phone before flashing anything from sammobile.com.
You may be able to use fastboot commands to get the information by typing fastboot getvar all.

OK, in Linux now. ADB/fastboot won't connect. Tried different USB ports and cables, ones that I know work. No luck...
The only thing I can boot to in the phone is Download mode, so that's where I'm trying from.
For the record, ADB picks up my Nexus 5, so I know it's all set up right.
I'm gonna retry the debrick img, using dd to write it this time.

No luck. wrote to the SD successfully, and it just boots to download mode. Nothing else.
ADB and fastboot still do nothing

Maybe the phone's USB port is flaky?
Have you tried Kies to see if it recognizes the phone?

I don't have Kies, but I'm doubting that would work anyway. There's absolutely no communication between the computer and phone. Nothing happens when I plug it in. No sound, no indication anything was even plugged in. Running lsusb in a terminal doesn't show the phone either.
Edit: Downloading Heimdall (Linux-compatible Odin)...

Okay, forget kies. Sounds like a USB port issue. Does the phone start charging when connected to a power source?

Plugging into the wall makes the phone vibrate every couple of seconds, but nothing shows up on screen, and there's no indicator light.
The vibrations lead me to believe it's detecting something, but no indicator light worries me (unless that's just because there's no kernel)
The red light does come on if I plug it in without the battery.
Heimdall fails to detect the device as well (no surprise there)

If the phone was bricked, it would usually be recognized as a some sort of device under Windows' device manager which leads me to conclude that it is a USB port issue.

I agree that it is weird, because it's not coming up as a device at all, in either Windows or Linux, yet it does receive power.

I'm guessing here but it appears to me that the only left to try is a debrick image. Is it possible the battery is drained and needs to be charged?

The debrick image is what I've been trying. It's on a 64GB microSD. And I made a new one from Linux a few minutes ago (booted back to Windows now).
The battery was about 80% before all this started, and the phone powers on without being plugged in, so I doubt it's the battery.

Maybe you need a different SD card? Based on posts I have seen, it seems that certain brand/size combinations work while others don't.

I only have one card over 16gb...
Either way, I still have the USB problem. I'll need USB to flash with Odin. The debrick card only seems useful when Download mode isn't working, but that part works fine on the phone, even without the debrick card. My problem is with recovery. If I could run that from the SD, I think I would be fine - just flash a ROM. But I'm not finding anything for that (not surprised).
I thought it could potentially be a corrupt driver, so I tried using USBDeview to uninstall all disconnected devices. I tested it with a portable hard drive, which indeed had to reinstall after. So the program works as intended. However, the phone still isn't detected when I plug it in. No sound, no notification saying it's installing or install failed - absolutely nothing. Power goes to the phone through USB, with multiple cables and USB ports. Just no data connection.
I'm starting to think there's just nothing I can do...

The phone may need a USB port replacement. I know of no way to push recovery to the phone from as SD card without USB capabilities.

Yeah, that's what I'm thinking. Found this, and it's cheap enough... But that shipping!

You'd be better off getting it from China with free shipping. The problem is the amount of time required to get the part.
Maybe contact a cell repair shop to see how much it would cost to have them replace it. Soldering is not my strongest skill

Yeah, doesn't look easy. I already tore down to here, and visibily, it looks OK. I'm not so sure about soldering either :silly:
I appreciate your assistance.
