Man, I messed up my phone!!!! EPIC 4G

Here's my situation:
SAMSUNG EPIC 4G
I've updated roms without problem many times since buying my phone. I am currently on 2.3.4, gingerbred eh06. I cannot get the usb to work with my pc at all. I'm assuming that since the phone still charges, the usb is functional? I was going to try a flash back to stock ec05, but cannot do this because I don't seem to have CWM installed. I did, don't know what happened to it. All it says when doing a cw boot is android system recovery <3e>
I tried to follow the link for rooting my phone without a pc, but cannot get it to work because I don't have superuser access. I did but don't know what happened there also??? Apparently gingerbreak doesn't work on 2.3.4 from what I am finding. I'm about at the end of my rope here and am looking for somebody to throw me a bone. ANY IDEAS.
I should also tell you that I know the cables I have are good. I have 2 samsung and 4 aftermarket cables and they all work. My wife has the exact same phone and works every time, with every cable. Of course her phone hasn't had any "custom" work done to it if you know what I mean...

Try Heimdall. It installs its own drivers and is more robust. Post 2 in Development stickie of how to fix a semi-bricked Epic.

Tried that just now, didn't work. When I tell it to list devices, it comes up as unknown device and won't install any drivers. tried my wife's phone and it seemed to work just fine. Maybe the phone can charge with a broken usb port?????? AAAAARRRRGGGGGHHHHHHH!!!!!!!!!!!!!!!!!!!!!!!!

so you have no root and no odin/heimdall?

Yes it can charge with a bad port or a bad cable. Since the cables are good some of your usb port may be damaged somehow. Did you check for dirt or debris in the port?

Right, neither works. Its not the pc either. Tried win 7 64 and 32 bit, xp pro, ubuntu, joli os. Nada

Thought about tearing down phone and looking for dirt/debris. Just loking for all possibilities. I did fing a usb port on ebay for about 50 bucks, doesn't really look like something I could replace myself. ;'m assuming that it's soldered in.

I believe non warranty repairs like that are only $35 at Sprint.

Good job Sprint
Just left the Sprint store and they gave me a new phone. Tried like hell to get an upgrade to the Galaxy IIs, but no go. I gave them a boo hoo story and even told them i'd settle for the Nexus s, but they wouldn't budge there either.... Oh well. At least I got a new phone out of the deal. Kudos to the Sprint store and their employees though.

This happened to me at first too, then my phone stopped charging the battery. Maybe this is a sign of the port actually going out? Right now, I'm waiting on my replacement through Sprint without a charging phone.
I was able to finally get a good working combination of my brother's Evo cable and Odin 1.7 to flash back to stock for warranty work.

HALP, USB port is borked

My computer can't see my phone via ADB or anything else, and the phone won't charge. I'm positive it's a USB port issues, as I have been able to connect to my phone before, flash ROMS, move files back and forth, etc. I've tried different cables and different USB ports. USB debugging is turned on.
I want to return the phone to stock before I try returning it. Is there a way I can do this without a USB port? Maybe use a stock nandroid or something? (even if I could do this last step, I'm not sure how I'd relock the bootloader)

you could use this to lock the bootloader https://play.google.com/store/apps/...wsMSwyLDEsIm5ldC5zZWd2MTEuYm9vdHVubG9ja2VyIl0. flash a stock rom that you could download from a web browser and you should be good

OK, thanks!

no problem

Post 3 of my guide has a link to return to stock and locked with no USB access.

If you want to do it without Mobile Odin, there is a (free) way. See here. I've set it up for maguro, but you can easily replace all the maguro images with the toro ones. Then use segv11's BootUnlocker app (linked earlier) to re-lock the bootloader.

Thanks guys, exactly the info I was looking for. I appreciate the speedy replies!

Also, there just seems to be a generalized hardware problem with the Galaxy Nexus' USB port, I myself sent my device in because of it, and they put in a new USB port which helped prevent the problem for a week and I was extremely frustrated when it came back, and of course XDA being the lifesaver Paradise, I learned that if you get a small object like a flat-head jewelry screwdriver and slide it under the tongue of the port and apply small amounts of upward pressure (But not too much, because if it breaks you could void your warranty) to the tongue. Apparently the Nexus' port shorts out when touching the bottom of the phone, I have been good for about a month with no problems. You could try this before warranty.

serious USB-port issues

Hello!
First things first: i already googled and search-functioned about 8 hours for solutions, tried them all and still got no luck so basically you girls and guys are my last hope. i hope my english isnt as rusty as i think it is. if i make any mistakes of any kind, please bear with them.
Used Hardware: Galaxy Nexus, the original Samsung OTG cable and the original Samsung charger
Software: Rooted, Bootloader-unlocked, stock-Android 4.0.4, 4.1.1 and 4.1.2
What is my problem?
as soon as i plug in the original charger it charges (duh!)
however, the moment i unplug it, the phone keeps thinking it is being charged. forever!
plugging in a original samsung USB cable without connecting it to something doesnt help, it still thinks of being charged.
but plugging in the original OTG cable stops the phone from thinking of being charged! (i dislike the thought of running around with a OTG dangling around the phone so that isnt a solution to me )
what happened before that incident?
bought on 15th December 2011
last software update 4.1.1 to 4.1.2 on 16.10.2012
worked perfectly until Yesterday
Recently i played around with the OTG cable and tried the following hardware to see wich works with my setup:
external HDD - NTFS formattet
PS3 Sixaxis controller
Corsair Flash Voyager USB3.0 Stick
AKAI MPK mini USB MIDI controller
Newest apps installed:
Sixaxis Compatibility Checker (18.10.2012 installed, used for half an hour and deinstalled)
Wolfram Alpha (17.10.2012 installed)
MyBoy (an GBA emulator - 12.9.2012 installed)
-latest ROM for that emulator downloaded on 13.9.2012
what did i try to fix the problem (in exact order)?
rebooting
changing the battery from 2000mAh (its an original, bought about half a year ago) to stock 1750mAh
removing the battery for 10 minutes
draining the battery to absolute zero and fully recharge it
carefully cleaning the microUSB port (with battery remover of course)
super carefully bending up the thounge-like part inside the microUSB port so that it doesnt get in contact with any surrounding metal parts (battery removed of course. when i say super carefully, i mean super duper carefully! i know how fragile those parts are!)
trying to hard reset the phone (that was a failure i just got from fastboot mode to a droid with a red triangle and an exclamation mark on its open stomach)
factory resetting the 4.1.2 via factory reset option (backup with Titanium Backup was made correctly but i forgot to copy it from droid to PC :silly: )
wiping the cache via fastboot
quick reflashing the 4.1.2 via fastboot
quick downgrading back from 4.1.2 to 4.1.1
quick downgrading back from 4.1.1 to 4.0.4
quick upgrading to 4.1.1 (it still is in that state)
complete reflashing the 4.1.1
- with reflashing bootloader
- with reflashing radio
- with reflashing recovery partition
now i am out of ideas
i think the USB port is seriously damaged. but since i am not so good with soldering and electronics i fear that i am not able to exchange that.
any more suggestions or ideas what might have been the cause?
next few days i will take it to the service center wich i really dislike to do because here where i live that means they keep it for about 6-9 weeks to fix it and i will not get a replacement in the meantime. anyhow my hopes are low that they might fix it i rather believe they replace it for a new one wich i also would dislike. Good thing i made a insurance for that device so in worst case i dont have to pay a single buck...
greetings everyone

Weird. Did you try flashing a stock Google 4.1.2 image? (Check out mskip's thread in Galaxy Nexus Android Development and download the toolkit - make sure it's compatible with 4.1.2 first)

Yes your USB port is most likely broken. Many others have had this problem including me.
Mine was so bad that my PC wouldn't recognize it and neither of my pogo pin docks would work.
I replaced the USB flex cable this week and it works great now. It was a relatively easy repair if you take your time and have the right tools.
The part only cost me $7. http://www.ebay.com/itm/190704059979

thanks mohitrocks but i also tried that, not only once.
El Daddy are there some how-to's? If it is easy i will try to do this before handing it in to the service center.

The USB ports should be the same as micro sd is a universal standard I believe.

I had that same issue after my phone got wet. After about 2 weeks the issues with my USB port went away altogether.
You take your phone places where water might condense on/in it?

thanks miketoasty and thanks El Daddy! i really like this forum a lot very helpful people here.
i ordered the part. Estimatet shipping date somewhat between 30. october and 5. november.
will post updates
at least that error of mine doesnt drain extra battery
reuthermonkey:
i cant think of any place i visit frequently with high levels of moisture or with wet places. I am really careful about that because i love my Nexus witch even goes as far as never ever taking it into the bathroom (not even to a save and dry spot) while showering or bathing. Rain is a bit rare here and even if it is raining i wont leave the house without putting the phone inside a phone-pocket and into the inner side of my jacket.
greetings

I had the same issue as you. I ordered a new charging port cable for $7 on ebay, installed it in 15 minutes, and all is well in the world.

If anyone else is having issues, I have a spare USB flex cable that I can send you for just the price of shipping...most likely $3 or so.

Rooting without being connected to comptuer.

Hello XDA members,
Couple of weeks ago, I plugged my charger and then all of a sudden, smoked started coming out accompanied by a burning smell. I quickly took out the charger and now I am not able to charge my phone. I recently sent it back to Samsung for repair but they could not fix it under warranty and was asked to pay $200. Imo that is way too much considering brand new Galaxy Nexus is around $500 where I am from.
Prior to sending my phone, I unrooted my phone, reverted back to stock rom and now I am wondering if there is a way of rooting my phone without having to be connected to the computer via the USB cable. I want to install a custom rom but is that even possible without having the ability to connect to your computer?
Thanks

You can fix the USB port for a few bucks, i seen people say it cost $10, not really sure as i never came across one, but it should be out there on ebay.
You will be looking for a microUSB board

I am in the same situation as sgs064. I have a Gnex that I need to root, but it will not connect to the PC with the USB cable (strangely, it does still charge via USB). I probably will just fix the microUSB port as Mach 3.2 suggested, but in the meantime it would be nice if there was a way to do it without USB. I realize that it probably is impossible, as efrant indicated, but if anyone has any ideas, I'd be willing to try em out. This is an extra Gnex, not my everyday phone, so im willing to mess around with it a lot more.
Thanks.

Having a Number of Problems

Hello to all. I am emperiencing a number of problems on my deb. Some are listed below. These problems were not experienced in the first 3 months:
1) THE BATTERY
I cannot use the tablet while charging. It does not charge i.e. It needs to be in a specific position to charge.
Also, I am experiencing Huge Battery Drain. It charges 5-15% in 2:30 hours. This happened after I used the PA 4.5 beta 1(Using MultiROM. This stayed even after I deleted the ROM And reverted back to stock.
2) THE SIM CARD
I don't know when it happened but the sim was working fine before. I didn't use the sim very often except for validating whatsapp. But as I tried to validate, no messages arrived at my nexus. I thought that the sim had become defective. But it worked just fine in other phones!
I even contacted Asus about this but they asked me to first factory reset it. I decided it was too big a deal and did not.
3)THE OTG CABLE
My Nexus recognized the otg usb drive at first. When I tried to use it again, It just wouldn't recognize it. Tried using a mouse too (had worked before). Did not work. Tried on different roms. Nope.
4) USB COMPUTER CONNECTIONS
I had used it before to copy files from my laptop to my nexus. It worked fine. After some time, I tried to do it again, the pc would recognize it sometimes say it was unknown sometimes say it was Nexus 7 but wouldn't install drivers. Tried using Wug's to no avail.
Today, I tried using it on my other pc. The drivers installed just fine, but there was no sign of it in My Computers. In Wug's, the device was able to operate fully! It tried using various backup commands, and they worked! But the push/pull command did not work. Though that turned out to be a problem of the toolkit as I pulled the files I need with ADB PULL command in cmd.
So, as some of these problems are hardware related, I am thinking of giving it back to Asus. I am rooted and performing The Wug's Flash Stock +Unroot Option Now. Please if you have any advice, post it here.

Judging from the symptoms, you likely have a bad usb port. I wouldn't say the cable since your otg cable yielded the same result. According to some, it's really fragile when you handle it rough. The port is soldered to the I/O board so either you (1) try to bend back the inside pins; or (2) replace it if you're skillful enough with your iron; or (3) replace the board (ouch!). It's a shame if you have to choose (3) since that means throwing the board away for just one bad component. Litter.

1) The inside pin is fine. The cable just seems really loose. Though the other cables have the same effect.
2)I dont have the skill.
3)Why should I waste any money if It is under warranty?
And usb otg should come at least once, as the tab does charge once maintained in a specific condition.
And As the tablet charges when its connected to a pc, its not a problem of bad usb port

I didn't realize your tab was still under warranty. Nevertheless, the fact that the cables fit loosely suggest that the housing is not in good condition and the pins, in turn, while not damaged, make poor connection (to wit, the tab charged only if held in a certain position). If the tab consistently charges while connected to a PC, then you're right, the fault lies elsewhere, like a jarred battery connector, or the other USB end, or the charger itself. This, however, leaves the OTG issue unexplained. Warranty seems your best bet for the moment, however. Good luck.

I don't think it can be a mistake of mine, so Asus will definitely have to replace it.
Thanks for your support though!
