[Q] USB not recognized - Samsung Epic 4G Touch

OK, so I rooted my 4G Touch and everything was going along smashingly until I let my son play a game on it and he tried to plug the charger back in and broke the tip of the cable. Thankfully, it wasn't broken off inside the phone, but now ANY USB cable isn't recognized when I plug it into my laptop. The phone will charge, but I can't transfer data. I tried swapping cables and changing ROM's, but to no avail. I need to know if anyone else has had this happen and how were you able to fix it. If not, any idea on how I can unroot since Odin will not work without the USB connection? I would like to be able to send it back and have it warrantied, but I can't unless I can unroot it first.
Thanks!

I had the same problem but not from a broken usb cord.. I lost all usb recognition from flashing a botched gsm rom on a cdma phone..
I can tell u this take it in to a service center the reason being they give two cents less.. That its rooteD .. they are theyre to do a hardware repair not software.. them guys are good at what they do... they even add insurance on the spot if you dont have it.. just hand them the device tell em u think usb ports bad and say nothing else... .
I flashed bad software and they ended up installing a new motherboard in ten minutes i signed a Paper and was all set
thats my advice ..no real need for a replacement. They have more parts then phones .
Good luck

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.

USB Issues...

Hi All,
My SGS2X no longer connects to any PC for anything other than charging.
I've tried everything, trust me. I've come to the conclusion that it is defective and want to return it for a new one. The problem is that I have rooted it and need to undo this before I return it. Telus told me it would need to be sent to Samsung for testing before they will give me a new one, so I need to unroot before I allow this.
Is there any way to unroot without a USB connection to a PC or am I screwed?
Thanks,
Mael
you might want to send it in for repair, to have the USB port replaced
Try using a different wire this same thing happened to me i believe

every time my phone drops to the floor while plugged in, the first thing i always worry about is the usb port
because of those issues reported above
Tried different cables, same problem.
Same cables work with other devices and other phones...
Phone has never been dropped, plugged in or not, so must be a defect.
Seems like a defect to me and thus covered under warranty, only prob is that it's rooted, voiding the warranty. Hence the question on unrooting, but I don't think it's possible.
I may just put up with it for now... It's a hastle not having access to USB storage, but I can work around that. Once I decide what I want for a second phone (Nexus or Note), I'll buy that, then brick the GS2 and go for warranty replacement then...
Pain in tha a$$, but thems tha breaks...
just ... never mind
i was going to suggest Odin, but then i remembered, sheet no USB, no can't do
the stock rom can't be flashed form CWM on the external sd card? I didn't realize that ODIN was required to put back to stock. Just wanted to clarify this.
Have you tried blowing out your usb port on the phone with some compressed air ???
Had a friend of mine , brand new phone, his USB just stopped, it would charge, but nothing else ... Screwed with it for hours, then he blew it out, and it worked ..
Sometimes your phone just wants a good blow job, just like the rest of us ...
(yeah yeah rude crude and socially unacceptable , but hey still funny) ...
Never thought of that... I'll give it a try...

This thread describes a method for flashing a stock kernel and (somewhat) stock ROM by flashing the files with CWM. You won't need your USB port, I just don't know if the stock ROM linked to in that post, will pass for "stock" on your Telus SGS2X. It may be good enough to pass for a warranty exchange/repair, etc., or there may be a stock Telus ROM floating around that is CWM flashable.
Good Luck..
Have u tried the samsung usb cable that came with your phone? ive found samsung phones to transfer data with the stock cable...everything else just charges the phone....just a suggestion
Sent from my SGH-T989 using xda premium
Tried the compressed air, no effect.
The ROM on the phone is stock, all I've done is root and install CWM.
To al appearances the phone is stock, but for the presence of superuser and CWM.
Tried the original cable, no difference...
Telus told me to go where I bought the phone, so I'm going to try going to BB and raising a stink, see if they will replace it...
By bb u mean bestbuy im sure they will they are awesome with returns well atleast the one by my house i like there no questions asked hahaha

You can use something like dropbox to transfer some more stockish looking ROM on your phone, but i'm not too sure how to lock it without USB cable. I'm too lazy now to reboot my phone into bootloader, but wasn't there an option to re-lock it?
Anyway, if this will happen to my GN i'll just pay €30 for USB port replacement. I had same issue on SGS2.

well... to be honest, i think thats a lot of money that can be spent on a phone thats pretty new. With that being said, it is cheap compared to what i would be paying if i had to pay full retail price.
------
To update this thread, I got my phone and charger replaced free from verizon. Basically, i had a bunch of different roms downloaded and tried to install some good ics looking roms. They didnt really work as well as i wanted so it was an easy solution to "brick" (and brick is used very very very loosely) my phone.
1. Wipe data/ cache / dalvik
2. Install zip from sd.
3. Pick out a different rom and let it install ---- BUT WAIT
4. Pull battery in the middle of installation.
I had to do it a couple of times, but eventually i got it to the point where the only thing that would show up was the google logo.
My thought was that they would just reflash to stock in the store, but the rep didnt really know what he was doing. He probably figured i tried to root (he asked if i tried to root... duh, NO!), and probably spent most of the time trying to get it to come on and didnt bother putting on their falshing machine thing.
Anyways, Since it was still a phone under warranty and they had no evidence of it being unlocked or rooted, they replaced my phone as well as my charger for free.
------
Im just hoping they dont secretly put a note under my account that i might root my phone.

nexus not charging

i know it is already posted but my issue is different. Some can charge their phone when it is off but mine cant charge even if its off.
When its off and i plug the charger the lightning logo appears, it indicates that its charging but when i turn it on the percentage of the battery remained the same. it didnt charge at all. Also my pc does not recognize my phone whether if its off or on.
i tried with no luck changing rom, kernel, used different cables and chargers (i even used one from LG).
i want to take it back to samsung but my bootloader is unlocked, im using costume rom, and rooted. They will not accept or repair it
EDIT: i want to install the stock rom and relock bootloader but how? since my pc doesnt connect to my phone

Use a cocktail stick and try push the chipinside your phone slot upwards a little (if the phone were laid faceup on a table). Be delicate as you dont want to force it, but a little nudge up and your problems should aaaaall be resolved.
ive already done that no luck.
bump!
if i can restore my phone to stock recovery, stock rom, stock kernel, remove root will they accept it(warranty)? or do they have something to know that i modified my phone?
EDIT: because im planning to return in back to samsung
Please read forum rules before posting

Is it a play store model or international? If it is international and you are located in the USA, Samsung will not do it. You can replace the usb port yourself..
mine too
Mine did the exact same thing. Good luck sending it in and having them actually fix it. I'm beginning to think their tech guys are really just a room full of chimps randomly putting stuff together.
I told them exactly what the problem was (because I looked it up before sending it in and my problem was the exact same as everyone else's) and they ignored me and just switched out the battery. That didn't work, so I sent it back again. Then, they updated the software. Since it's a hardware issue, obviously that did nothing. Now, they have repaired the PBA. I don't know what a PBA is or what it has to do with my USB port, but I'm betting the issue still will not be fixed and I'll have to send it back, yet again. After all this mess, I think I'm done with Samsung entirely.

i have sent it already. fortunately i was able to return to stock without USB. Hope they cant detect that ive done a mess on my phone.
probably the repair shop where you took your phone are just too lazy to repair. I hope they wont do the mess they did to you but i think it depends on tech guys if they are lazy enough to repair.

Did you get it fixed?
This is kind of what my phone is doing too (here's the thread i've made)
http://forum.xda-developers.com/showthread.php?t=2059289
It will charge, but only to a certain point, regardless of rom, kernel, on or off, etc
over the past few days the maximum charge has gone down and down. Now it only charges to a max of 82%. I have 2 batteries and it does the same thing on each. My (hopeful) solution is that i bought an external wall battery charger and will charge batteries that way. I have the verizon model so if i wanted to do some sort of warranty work i'd probably have to go through them (not even sure if im still covered). I really dont want to deal with it. It boggles my mind why my phone is doing this though, charges fine but not to full. Oh well c'est la vie.

i wouldnt recommend that to people, for me it went from a phone with "phantom charging" (ie flashing on and off for charging) and issues charging to a short circuit on the usb connection, so that the phone switches off when a usb cable is plugged in. What is well worth trying first is simply giving the port a good clean, a little bit of alcohol and that same cocktail stick may well solve your issue. I've been left charging via a chopped up usb cable to the dock connectors.
i dont doubt that forcing the tab in the port may have worked for you, but it has failed badly for others (ie me), so just be careful suggesting it
I had a similar problem as my micro usb socket was damaged. Don't worry about sending it for repair, do it yourself. The circuit board with a new micro usb socket is available on ebay, I paid £5 for mine. Watch a tear-down video or 2 on youtube and you will be sorted.
The GNex is easy to take apart requiring just a small philips head screwdriver and a pry tool, i used a guitar pik, and these are also available on ebay for just a few ££'s.
Can do the whole job in 15 minutes.

[Q] My s3's motherboard fried?

Last week,before going to sleep, I put my s3 phone to charge before going to class. When i woke up in the morning i knew something was wrong because my alarm never rang.
Because i live in india now, I first called samsung and they told me I would have to pay 70$ just to ship it to texas center and then have to pay whatever the cost is to fix the problem.
Naturally, I took it to a mobile repair shop down the road. They first said my phone had some boot problem. After a week they said nothing could be done and that the motherboard is fried.
Here are the problems.. When i woke up, the phone was off and the charging light wasnt even showing. I kept trying to turn thr phone on and it tuened on once all the way to the samsung logo and sound and then shut off again. After that, it hasnt turned on since. Boot menu doesnr work. Download menu also doesnt work.
It doesnt turn on but the charging light shows uo when i insert thr charging cable.
What do you guys think? What should i do? Is my motherboard really fried? Should i try to find a new motherboard on amazon and try setting it up myself? I dont think my warranty is still active with at&t if that makes any difference.
Looking forward to any help,thanks.
Plug into a computer and check device manager. If it says qhsusb_dload or something similar it may just be bricked. If so try the debrick method in this section. Worth a shot before spending money on it.

After I plug into the computer..nothing happens.
Ill try again after i get home.
The phone is rooted. Though i havnt updated it in a very long time.
Also i should mention that sometimes the red charging light comes on and sometimes it doesnt. Also when i connected it to a different computer it showed a message rhat something failed to download.
Which charging adapter did you use? Was it the stock samsung adapter or an aftermarket one?
so after plugging in the phone to the computer, I tried to look for anything in the device manager, however have come up empty handed.
So, its safe to assume, its not bricked (as that is semi-reversible).
And that the phone is most likely motherboard fried...which sucks and means I have to get a new phone.
Is there anyway to extract the information from internal storage? like documents and pdfs and possibly notes? Or is that option not available aswell?
I am thinking it is a hardware failure at this point. I would say to check the USB port as those to tend to get damaged sometimes, but you took it to a shop already and they should've noticed it if that were the case. These devices are getting old though, and I've been seeing more and more hw failures lately, so considering all that you said in the op, what the shop told you and what has been discussed here I am thinking that will be the most likely conclusion.
As for getting your data back, I kind of doubt it will be possible. If a shop can't get to it with special equipment and programs, you won't be able to do much more on your own. If its very important/valuable data, you could always try a professional data recovery service, but you're probably going to pay a good bit for that.
I am sorry that this happened and that I can't be any better help to you. Good luck with whatever you decide to do. And feel free to ask for a second opinion. Its always possible I could've overlooked something.

Have you tried a fully charged different battery. You're USB port could be bad not allowing your battery to charge or connect to the computer. If this is the case, your battery didn't charge and went dead during the night and it also may not be getting power from the computer when plugged in. With another battery you might power up and retrieve your data.
S3 motherboard replacement
Hi guys,
I hope somebody here can be of any help. my i9300 (s3) got fried while charging last month. while i was planning to dispose the phone. due i cannot use it anymore and i bought one for good which currently in use, my co-worker just broke the screen of His phone too (s3), fortunately,he agreed to give me his and ask a friend of mine to replaced the motherboard on my s3 with the one from my co-workers phone. the replacement proceeded successfully but upon testing any sim card does not work. it display it has a coverage bar signal, but the notification on top says no sim card.
anybody who would share a thought about what will be the solution is much appreciated!
thanks in Advance
