My Epic wont get recognized by any comp

Would appreciate it if someone could tell me how to fix this. It was always a problem my or any computer i used would never find my phone when i connected it via USB. I always got something saying usb port malfunction and when i go to my computer phone never shows but phone does charge through the usb so it is connected. Any help here would be appreciated.
P.S ive tried about 5 different usb cords and atleast 5 different computers even ones on campus

Take it to the store...

Get a new cable...a heavy dudty one like a Blackberry or Palm. It takes nothing to charge through the cable but a lot to pass data.

.. i had same problem: tried many cords, comp, reinstalled drivers, etc.
Finally i odined the phone as if it was bricked and all was well.
To make long story longer.... initially my comp would ID my phone great, (I rooted, mass storage the card,etc). but i took the phone to Sprint for other problems. I dont know what they did but my comp did not recognize my phone when i got it back, no matter what i did.
Odined the phone and poof! everything was back to normal.

HELP! i think i bricked my new galasy s 2

i just bought the tmobile galaxy s 2 and was trying to root it. obviously i did something wrong and now its stuck on a black screen. it will not power on AT ALL and when i plug it into the usb it looks for driver QHSYSB_DLOAD. ive tried everything someone please help. i will pay someone to fix my phone if i have to

You need to get in download mode and odin back to stock. Pull battery and put back in. Go to different computer, win XP works best, download/install drivers on PC then plug phone in to PC and download mode should come up.

Also you may have to hold both volume buttons down. It works both ways with and without volume buttons. Search threads how to get in download mode.

It's bricked. I had the same thing happen a few days ago. Just take it back to the T-mobile you bought it from (assuming you bought in-store) and they'll replace it. Seeing your phone recognized as that "QHSYSB_DLOAD" device seems to be an issue with Qualcomm CPUs and happens mainly to HTC phones for obvious reasons. From the hours of research that I did before returning my phone, no one has ever successfully recovered from that kind of brick.

i bought it used so tmobile wont replace it. BUT i registered the phone on samsungs website and it says its still in warranty with them. do you think samsung could replace it?

Yeah I'd do that. They should be able to help you out as long as you don't say you were trying to root it lol. Yours won't vibrate or anything when you press the power button right?

nope it doesnt vibrate. what do you think of this?

Yup, mine wouldn't vibrate either. The only sign of life was when it was plugged into the PC in an attempt to get into download mode. I read that when you get to the point where the phone can't even get into download mode properly(showing the usual warning about custom OSes, that the jig device won't work, unfortunately. It may be worth a shot though if the price is right.

just shipped out to samsung. hopefully they dont realize why its broken and try to charge me for it

Quick Q: Jedi Mind Trick Brick? Phone unresponsive;Veteran User

phone wont boot at all after install. wont even go into download mode.
phone worked perfectly when i was running beastmod 3.0 i believe. i stayed inactive ever since.. i made sure i could get into download right before i went ahead to the jedi mind trick update. like i said, everything worked perfectly. tested out all button combos for recovery and download mode (even did the pulling the battery and plugging the usb method) with success before i updated. yes phone was on 100% battery . it was on the charger the whole night.
i logged back on because i felt like updating and read about Jedi Mind Trick. installed TWRP recovery as well a few days ago. i wiped everything of course, flashed, repaired , reboot. I got a black screen for awhile and let it sit for 30min. no response, so i pulled the battery and tried to turn on. phone wouldnt turn on so i tried to get into download mode and failed. phone is completely unresponsive.
what to do? i'm just stumped now. i was inactive, but by no means am i new to this.

Are you sure your battery has a good charge?

I see by no means are you a rookie but I will ask have you tried to plug your phone in to your pc and see if it makes a noise and recognizes it. Honestly I would assume prior to posting you probably tried everything so it may be unfortunate but you may have to send to JTAG or go through insurance.
Cant see a rom doing that to your phone? Unless you had some hardware failure

Have you tried using a usb jig to force it into download mode?

yes. i made my own actually. it was the first thing i used to make sure i could get into download mode,with success, before the flashing process.

after flashing:
1) i did plug into 2 laptops(windows 7) and a 2 desktop(vista and xp). "tries" to install the drivers and then makes the fail noise.
2) tried to use the SGS2 toolkit as well.
prior to flashing:
1) phone mounted successfully to 1 laptop and 1 desktop. thats all i tried it on. i used my laptop to transfer the flash zips and my desktop to back up my internal memory since i havent done it in awhile.
2) everything just worked. my only gripe was that my phone was still on gingerbread and decided to update to to ICS
i'm just puzzled myself. i did try everything that i could think of to at least get the phone to turn on somehow. i even went back to sleep and put the phone on the charger hoping the phone would just magically turn on itself >_<
i know i've been super inactive for awhile, but it only took me a few of days to get myself back up to speed and catch up on the new information.

Also would like to add that i used 3 samsung micro usb cords(2x sgs2 and vibrant),jig,2htc cords(hd3 and mytouch 4g) and even my old nokia micro usb. No success but at last the laptop is detecting the phone when trying to install drivers and then fail.
I know i did not download thw wrong rom either its not like i go off to other phone sub-forums to look for stuff.

Chalk this up to bad luck and move on. Its not the ROM. Period. Like pmtr3 said, 20,000 downloads plus, and your the first one to say this happened. Sorry to hear about your phone.

Have you tried pulling the phones battery out sim and micro sdcard... then hold the two volume buttons then olug in the usb and then place the battery while still holding the volume buttons? (Open up odin before trying)

i have no clue what happened. maybe some kind of freak hardware failure. i used to be so into flashing,but decided to use my phone as a phone instead of always flashing.
i did call TMo for a warranty replacement, but the SGS2 is supposedly on back order -____- they recommended an alternative device,but not details yet until they get back to me.
this isnt my first SGS2. i got mine during TMo's firesale on Nov. 19th. 3 days later, i exchanged under the 14day grace period it due to horrible data drops and robotic voice. The phone was stock at the time. Data drops made it impossible to download-on-the-go for whatever the professors assigned . 2nd one worked like a charm.

yes....i'm cutting my loses and doing a warranty exchange. Hopefully an SGS3 due to having 2 SGS2's. Usually,they will upgrade to the next device if your current device is not available and you had 2 replacements.
i'm trying to find my Good ol' G1 that never really failed me. i used to like using it from time to time whenever i had my vibrant just for nostalgia purposes.

[Q] USB connection Issues

For the past few days i have been racking my brain trying to figure out what went wrong.
For some reason I can no longer connect my phone to my computer to transfer/move files. it acts as if the drivers will not take. when i check the device manager it reads SAMSUNG_Android with the yellow !
I have reinstalled lastest drivers from Samsung site, removed all drivers and tried from Kies software/ rebooted pc and phone countless times. tired my laptop where it use to always work and same results. One this i did notice was at some point i got an error on my internal sd card and that i should format it. I backed up all files via ftp formated the internal sd and tried again.. all with the same results. I have also tried 3 different cables.
PCs both windows 7 one 32bit the other 64.
Phone e4gt rooted FI27, everything else stock
All and Any Help greatly Appreciated.

Here it comes!!
I'm hoping that I'm wrong BUT, that is exactly how my EMMC brick started. Let us know if your phone just shuts down and the only thing you will get is a blue light. There us nothing you can do then but take it back to Sprint for a free replacement. I couldn't figure my USB issues out for maybe a week and then it just died when i plugged it in to transfer photos I'd just taken 30 seconds before it died. Lets hope I'm wrong but I'm writing this with my new phone ate the exact same symptoms with my previous Sammy. Try to get your internal memory backed up now! Boot your CWM and mount your external USB. I wished I'd have.

Try a brand new cable and see if that helps. This phone seems to be especially intolerant of if connections.

Not sure what you mean by boot my CWM. External memrory is ok I can just pull that out. the internal I backed up with FTP was a pain but i did it. I hope you are wrong about the phone dying out on me I am sure they will give me a referb if that is the case.

I still say try a brand new cable. When I first had this issue I tried 3 or 4 old ones before buying a new one.
Today my brothers nexus s wouldn't charge except with one particular cable. I think that the cable and port are still within individual tolerances but together there is just too much play in the connection.

took your advice and tried a brand new cable. I am stil having the same issue. anything else i can try? I tried with both usb debugging on and off still same issue

Damn, I was sure that'd work. I guess if you were able to back it up it's time for a replacement.

I think I bricked my EPIC 4G -- Please help!

I know there's been several threads on this in the past and I've tried most if not all of the solutions in them (except for the JIG) to no avail.
My EPIC 4G was on stock GB and I tried to ODIN GB08 as per this thread. The process failed (the message didn't tell me much) and left my phone as it is now. No lights ever and no way to go into download mode or recovery mode.
I have:
- tried to go into download mode by pressing 1+Power without the battery or SD card and then inserting the battery
- tried to go into download mode by pressing 1+Power without the battery or SD card and then plugging the phone via USB (using different cables)
- left the phone charging overnight
- left the phone without the battery for a while and then attempting the steps above
Nothing. Not a peep. Not a little light or sign of life anywhere.
Did I fully brick my phone and have nothing to do other than use it as paperweight or sell for parts? Keep in mind I'm no longer on Sprint, so I don't think I could get it repaired by them.
Any help is appreciated, except for the little reset button under the camera. Let's not go there again. LOL

Don't flash ROMs designed for the Epic Touch 4G SPH-D710 on your SPH-D700 Epic 4G.

OMG!!! I didn't even realize! I googled "EPIC 4G ODIN GB08" (is that even the latest stock ROM?) and that was one of the results. I didn't even check!
Anything you would recommend at this point to get my phone back to life? Remember I'm no longer a Sprint user.

If you are indeed on our device, SPH-D700, and flashed a SPH-D710 ROM, then you're hosed.
Our device's last official release is FC09.
Learn from the mistake.

God, this is so ironic! The phone was perfect yesterday and the only reason I was upgrading from GB was to enjoy it for a little while as a backup WiFi only device and then sell it. It's MINT. It looks like it just came out of the box. Not the slightest scratch anywhere. That's how I kept it for the whole year I used it as my primary phone. And here I thought Samsung devices were unbrickable, since you could overwrite ANYTHING on them with Odin, including bootloader.

Someone on that forum suggested I buy and use a JIG. I wasn't really sure what it was, but found many on eBay and the description sounds like what I need. They claim to get you into download mode even if you're bricked. Is that wrong or non-applicable in my case after this huge screwup? Would this one work?

To my knowledge, a jig should do the trick, but I'm not entirely sure. Only way to really find out is get one and try I guess. Or maybe someone else will pop in and answer.

That would be your last bet basically. If it doesn't work then you definitely have a paperweight on your hands.

You completely didn't read this thread. This guy flashed an Epic Touch rom on his Epic 4G. He's tried all normal methods of forcing download mode. He's at the last step before considering it a paperweight, which is using a jig.
Read and understand what is being asked and suggested prior to blindly posting.

i think I'm bricked too, any updates on the Jig method?

We're just waiting for razor1973 to update us on it.
Sent from my SPH-D700 using Tapatalk 2

Oh, sorry for the delay. I got the jig and it didn't work. No download mode. Nothing. My mint EPIC 4G (it doesn't have the slightest scratch of scuff anywhere) is now a paperweight because of a silly error on my part.

I have a bricked sph-d700 and noticed after fooling with it in the dark that when trying to get into download the device actually comes on. The screen lites up a little. It then won't turn off without pulling the battery. So, after every attempt to get into download pull the battery.
My problem is I can get into download but Odin does not see it. I have tried on a windows XP machine and Vista 32 machine. Windows see the device (Unknown Device) but does not recognize it as "Samsung USB so and so". Is"unknown device" good enough for Odin to see the device? I have tried several driver fixes and the cable I use I have used for data transfer and flashing another Samsung phone.
Where do I go from here?

Next time start a new thread for your problem; don't hijack someone else's. You sound like you have driver issues. Use a different USB port and if still nothing, another computer.
