I was. But a stroke of luck brought me to stumble upon the solution. If your USB connections won't work for crap... do this at a terminal emulator. No root or custom kernel needed.
Code:
echo 1 > /sys/class/sec/switch/FactoryResetValue
You're welcome.
Thanks to UberPinguin for his kernel patch to enable kernel messages over USB, which led me to check out the other items in that directory.
EDIT: It's 7am and I haven't slept yet. I thought I posted this in general. Post reported.
EDIT2: This method isn't guaranteed and may not work more than once.
EDIT3: And for those wondering, my device is not back in service yet - this method worked once, then the problem changed.
Awesome konane. LOL about your posts edit though. GO TO BED!!!

what terminal emulator did you use?
I have been having this problem for a while now, but I couldn't get this one to work either. Still holding on to some hope
Epic Stuck on DK28
Have you guys tried using a different cable other than the samsung stock one? I've been having USB issues forever on various computers/OS's and NO ONE on the entire internet knows how to solve this--all leading to unknown device. I tried a different cable and suddenly it worked...I haven't seen my folder pop up via USB since I first got the phone until that.
I have tried upwards of 6 different cables (Blackberry, HTC, Motorola, and other random ones) and none of them have worked.
I had this problem on my phone and sent it in to Samsung. I wasn't able to get the device to recognize on the computer (checked with multiple cables, machines, lspci, etc). It was covered by warranty, but I went without a phone for over a week. This is what Samsung's repair log said:
REPLACED CONNECTOR AND U606
I'm not sure what the U606 is, and was not able to identify it in the teardown here:
www(dot)chipworks(dot)com/en/technical-competitive-analysis/resources/recent-teardowns/2010/09/teardown-of-the-samsung-epic-4g-smart-phone/
Since receiving my phone, I haven't seen the problem again.
Have you guys tried this?
Its crude but worked for me. All my phone was doing was charging, no mass storage, no usb debugging, etc. A little poke and like magic, I was back in business. I recommend using a guitar pic
When you mention that you moved the center slightly down. Does that mean more towards the center or towards the upper edge?
I guess either way this didn't help me

This fix worked for me...used a small leafing knife and just kinda wedged the middle pins slightly up and "out" of the Jack...charging normal, computer reads now...YeEeEaAAA
For anyone who fry's this...just very lightly "baby bump" the prongs....they are very weak and snap off VERY easily....hence the original problem

Ok. Thanks.
I'll try it again when I get home tonight. I dont really notice any of the small pins within the device... Mine might already be broken off.
I tried. Moved it up towards the top of the device. Nothing... probably SOL
Ok so maybe I spoke too soon. Yesterday I was telling my brother that the Note is the most reliable phone I've ever owned.....then....
I started having issues with charging. My Note would not charge, then it would change after several resets. It would charge, then stop, then start again etc etc....making a lot of beeping noises.
Now, it seems to be charging, but Voice talk keeps loading, and I've turned off the home key activation option. I also get the notification icon saying to disable car mode.
I really hope someone can help, thanks in advance.
kris
Great, now it's not charging, again!
Actually when I get the notification issue from Voice talk, the battery starts charging for a second until the notification disappears and stops charging....
Now factory reset my phone again and charging worked while restarting and restoring but when loaded the voice talk app keeps coming up and going off, so I have a black flashing screen constantly....gonna try restarting/reset without restoring...
Hi leicashot, this shouldn't happen. Which firmware version are you currently running? I recommend installing the latest LB1 stock, unless you have AT&T Note.
Some users have reported similar symptoms when there was dust in the mini usb port. Try cleaning the device, and if all else fails, you should send it back to Samsung for repair.

I'm using the latest 2.6.35.7. Any idea how to try clean the port? Definitely seems like something is wrong with the port....
No charging issues for me but my Note started doing the driving mode thing at about 3am today and has been doing it on and off all day!
Exceedingly annoying!
are you trying to charge from a PC or a wall outlet?
I usually charge via mains but it wasn't charging or even plugged in at the time this started happening. It was just sitting on the table by my bed. I even powered it off but it switched itself back on!
Here is how to fix it.
Take out the battery and take a plastic edge like credit card or even a regular tiny small screwdriver and push the pins (strip) inside the phone. I mean, to take the screw driver and push in the pins back inside the phone, in inside the usb charging port. your problem will disappear. make sure your plastic flexible after-market phone cover has a big enough hole at the bottom to allow you to connect a usb cable easily to the phone, or else, cut open a bigger hole on the cover.
Good luck
so here it is again: you have to push in the usb port pins back inside the phone, straight in without bending them. you can also buy a usb charging port from ebay for 22 bucks and change it yourself in 10 minutes. its a hardware problem so stop resetting your phone.
Nop bro i dont think so, cuz it happened same with me sometime after i bought galaxy note same thing happened with me too. I mean exactly same. So before i didnt knew rooting and flashin roms and all so i gave to service centre and they put newer version of ron in it and my problem was fixed after that.

Indeed. I remain convinced this is not hardware and is software related. The main reason for my thoughts there are that as well as the driving mode thing it seems that some piece of software is trying to load up as it asks me if I want to run whatever it is in either Clock or TuneIn Radio. Bizarre. Also, the first time it happened it was bang on 3am. Everytime I turned the phone off it would come back on exactly two minutes later.
The second night it started doing it bang on 1am.
I'm waiting to see what time it starts tonight.
It doesn't (so far) do it at all during the day.
Going to give it a couple of days to see what happens then go figure out how to go back to a factory ROM rather than the the Rocket 22 I have on here now.

Same thing is happening to me. I tried pushing the USB pins in slightly. I'll let you guys know if it helped or not.

I've been having the same problem for a few days now.
I've just pushed the pins in with the corner of my charging cables connector and the problem stopped.
There was also a notification that flashed up saying something like: USB connector or device removed.
Voice talk is still managing to launch itself, even after pushing the pins in. I'm on stock LB2 so maybe I've finally found a reason to flash a GB rom?
Happened to me yesterday. Got a toothbrush and cleaned usb port on phone. Now seems ok

Hi guys,
I tried to update my Standard U8800 with Pro version by accident, the installation failed and when I pulled the battery and tried to start the phone it simply remains dead.
Tried pulling the battery off and on countless times, tried to charge it for a bit, tried it connected to the pc, etc. Hard reset doesn't work.
Is there any way to recover the phone?
It's still under warranty so I can just take it to the store and say it simply went dead and doesn't turn back on but I'd like to fix it myself if it's possible.
Help appreciated, thanks!
Im not sure but the case could be that your motherboard needs to be replaced, somebody who knows more about this stuff can hopefully tell more

Well,
My Lepro 3 has a very very strange problem :
Everything started Monday : it was at 20% and he just switched off, and then did 0 sign of life for like 4 hours (it was charging, but no led, etc..). After those 4 hours, the red light started blinking but still. And after 1 hour, I was able to boot (he had 10%). I decided to reset the rom, however, there was no way to get the phone recognized by my computer. I then decided to go to sleep and to charge to 100% the phone. Of course, nothing changed. And i even realized something worst : it takes like 5-6 hours to get to 100%, and it was 1h30 before.
FURTHERMORE : my lepro 3 isnt recognized on any PC, and neither in fastboot mod.
PLUS :
- when switched off, he won't power ON if i plug him to usb/sector.
- when powered on, he will vibrate TWICE when plugged to usb/sector : charging for 1 sec, then not charging for one sec, and then charging (like if he was trying to fast-charge, fails, and then switched to low-speed-charging
- when switched off, i sometimes need to press power for 10sec+ to get him booting
- I tried different cables
- tried usb debugging on/off
I don't know what i can try.. the only way seems to reset it with adb-wireless by pushing him a new rom but well..
I think it is a problem with my USB-C port (lepro 3 side) and i guess it is not using fast charging anymore
However, my headphones (usb-c) still work
Thanks in advance...
PS : I forgot to mention that i am running with Cydras Google-like rom 0.20S
I would switch to see makes a difference I have used that ROM without issue

Well I don't really know how to change the rom with no USB access.. Dunno if adb wireless is safe
Moreover, since the phone doesn't power up when off and plugged.. I guess the rom has nothing linked with this.. But maybe i'm wrong ! Could it be the kernel ?

Usb was working before
I just realized that when the phone is off :
if :
i plug it : nothing happen
i try to power it on : it vibrates one but doesnt boot
I need to unplug it and then to power it on
EDIT : I just managed to install twrp with flashify, but i would like to know if it will be useful to install a new rom or if it won't change anything....

EDIT : With the new rom (AICP 7.1.2) it's even worst : doesn't even charge when android booted, the only way to make it charging it to boot in recovery mod and to plug it

Yeah I tried..
It sounds like your usb card is fried.
I had this exact issue 2 months ago, I was lucky that the vendor exchanged it for a brand new phone.
It was probably fried by your usb cable. See if you can exchange the phone under warranty. Ask the vendor that you purchased it from, to honor the warranty, since contacting Leeco is difficult. Worst case, you will need to replace the USB card, its about $10.
VYeah, i guess it's the USB card... But there are two problems :
- its pretty Hard to disassemble a lepro 3
- i think that the original pro3 USB card comes with the vibrer, the speaker, and the microphone, and i didnt find any USB card with all of this on aliexpress...
He is no longer under warranty (15months vs 12)
Edit : another strange effect is that on cydras's ROM, the phone actually charges when powered on (but slow). On AICP 7.1.2, it juste says "plugged, not charging" when powered on

You are either bricked or its your battery, if bricked and the computer doesn't recognise the phone it still might recognise the port

Hey tsongming i have read quite a lot of posts from you in the last few days before commenting, i already tried before hand everything you said to get my phone detected by my computer and it still dosent get detected:
- tried multiple computers
- multiple cables
- and just in case, different driver versions.
Tried it all except the EDL Amazon cable you recommended in another one of your posts.
I have read that if i can't get it detected then theres nothing i can do.. which would suck.
ATM i have google pixel, beforehand i had AICP which worked really horrible on battery issues and would sometimes crash it. I have been using stock cable for 2 years which as i've read it the past few days is a terrible a ideia, and stock charger but as you say and qualcomm, i also believe its ok.
At this time i believe the problem might be a burned USB Card or the Battery itself bugging out(?) but since it charges when turned off (e.g: charged for 8 hours in supercharge to 84% =S), im clueless.
Since you said that you had the same issue on one of your Leeco, anything else you can recommend for me to try?
P.S: its worth noticing, i can Fastboot, Recovery to TWRP and turn it on, if indeed bricked i would call it a soft brick i guess..

If you can boot to Fastboot and Recovery, Then its not bricked. Your software is probably corrupted from a power spike or short. Its possible that your issue is just the USB card, which you can find for under $10, on Alibaba, Ebay and even Amazon.
Note that when you remove the screen do not use a Hairdryer to heat up the glue, there is way too much glue! You will need to briefly use a heat gun , and the screen will slide off with ease, the display and battery connectors are the lego type.. There are demonstration videos on Youtube.
Since you are removing the screen, you might as well replace the battery while your at it ( It should not cost more than $12)
If you want to buy a Backup LCD they are about $18 to $25 . ( definitely, recommend since there is a good chance of breaking the LCD, that you currently have)
If you order the screen, remove your LCD screen first to make sure that you order the correct one. They come with either black or yellow Flex cables ( not sure why) But if you have yellow obviously order yellow.
Make sure that the USB card is all inclusive and includes the chips, you are better off to spend a few dollars more for the better quality board. Sometimes the cheap ones come with missing chips for quick charge and CDLA ( Read the reviews)
Good Luck.
If you don't feel comfortable doing this, you can find Leeco Repair with a Google Search, or you can use TaoBao to get a "guaranteed fix", for really cheap. ( Even if its the motherboard ) They replace components and resolder) I doubt its the motherboard, but it's possible. In my case, I fried the motherboard and the phone still came on , but would not boot to system, also the screen was very pixelated.
