Green screen

Buddy's Epic. He screwed it up. Iwas flashing with Odin (from a flash drive plugged in to computer, don't ask and don't do it) to stock. Halfway through it did this. I managed to fix it, but i wanted to share this picture.

Tabbed on my Galaxy 987

This has happened to me! Trust me, when you see that screen your heart sinks, haha. But yea it's either because the USB cord you are using is not good, or the USB port is not good. If you're on a desktop try using the USB ports on the back of the computer.

It ended up being a bad cable.

Yeah I would have just about **** myself. Glad you got it fixed.

I get those screens ask the time flashing with odin. I just remove the batt and put it back. Re Odin. I notice the usb in the back of the pc works best. I also noticed I'm getting the color screens almost every flash attemp with odin. Not bricked, just crashed. But have you ask figured out what exactly causes those crashes? Is out really the usb cable?

Well....at firat a bad usb cable prevented the pc from detecting the phone. It would charge. But no data. I got the green screen a couple of times when flashing from Odin that resided on a thumb drive (along with the rom). I then moved everyting to local C: and it flashed fine afterwards. Don't know if it was a coincidence or a problem with using flash drives. This was from a Dell Precision Workstation with XP Pro.

oh wow I think I would have screamed in horror~!

Yea I would freak the hell out. Considering I use my phone for work, and the fact I had to pay full price for my Epic. Never done a Odin flash before, anyone have any tips and tricks for a fist timer? So I will go down the road he was in.

Warning! Do not connect PS/2 Keyboard via USB OTG (PS2 Adapter)!

Just a warning to everyone who values their PS/2 keyboard / mouse. I ordered a PS/2 to USB connector and tried to connect the keyboard to the phone. The result was a fried keyboard that flashed its Caps / Scroll / Num Lock lights at a constant rate, and after a reboot of the computer, 2 of the 3 lights were on at about 10% light. This happened to me with a generic HP keyboard. Obviously the keyboard never worked again.

Disassembling the keyboard I could make out a bit of burnt electronics smell.
Yay, Samsung!

Great stuff. 1st device to be killed by being plugged into an S2? I've attached all sorts of random crap to mine via OTG and not managed to fry anything

YOU can use this application wifikeyboard it work very nice without otg

Luckily it was only a generic HP keyboard, although it was the most comfortable keyboard I've ever had.
I wish I had known about that app before I plugged it in.

u need just wifi in your pc and router of course or use : connectify software to turn your pc as router than install wifi keyboard from market
and try it and you don t need to use otg

The Lesson here is...
USB OTG is meant for real USB devices only, not something that requires an Adapter to convert it to USB

but Thanks for being our Guinea pig, now people will know what to expect

Yeah, I guess I trusted my SGSII too much and thought it was capable of handling any USB device.

But it wasn't a USB device though.

Yeah, but I just thought, if it connects then it should work. I don't see why it would have burned it though, if the computer can work fine with it.

USB Device not recognized - MTP Initialization

Ok, not sure if this should go here or the Samsung Epic 4g Touch Forum, as this is my phone and where the issue occured, but I figured this could apply to other phones and wanted to help whoever out.
Anyways, I had the phone for just two weeks and one day I connected to my computer with a micro usb cable, and the computer would fail to recognize it saying "USB device not recognized..." I tried everything including different computers, cables, reinstalling device drivers etc to no avail. Come to find out, I plugged the micro usb cable into the micro usb more firmly and pushed down on a little bit, and finally recognized the device. I guess the port was wearing down over just two weeks and the connection had come loose.
Anyways, wondering if anyone had this issue and if it was repairable as I can see the port getting progressively worst with repeated plugging and unplugging of the device. Thinking samsung would have been able to have built a more durable mini usb port for such a nicely designed device.

Well first, you were right with wondering if you were posting in the wrong place. This is the original epic forum, not the touch. Also,this question has been beaten to death already. Either your cable is faulty, or your drivers aren't fully installed. You can also remove your battery while in download mode and that can help it being recognized.

b16flybye -- I think I just said it wasn't the usb cable or drivers and that it was the actual micro usb port on the phone that was causing the issue.

If you truly believe that it is the port, you can get it replaced at a Sprint store.

and sorry I meant to post in the general forum. I will move my post.
Gavisann -- Yea, it is the port. Once I push the cable in further, the device will recognize it, but once I let go, it loses the connection.

He also meant wrong device. This is not the Epic Touch. It is the Epic forum you are in...slide out keyboard...1 1/3 years since release.....

He's a long way from home. Good luck with your...port, or cable, or whatever the hell the problem is. Sounds like you knew the problem before you posted in the wrong place though.....

Camera relocation

I'm installing an HTC flyer in my car permanently where the radio would go (2DIN mounting), but kind of sad at the prospect of losing camera functions (video of dashboard interiors are boring).
So, what would be involved in removing the camera module and placing it somewhere else, as the dash for example? Would I just need to unsolder the camera module, solder on a whole bunch of cables, and connect them to the same contacts? Or am I barking up the wrong tree?
Alternatively, if a device has USB OTG capabilities, is there any way to make it talk to a regular USB webcam?
Discuss

Alot of research could go into what you're trying to do.......
However, I'd recommend just trying it and see what happens. Make sure your wires are all the same length.
So yeah.. In this situation, i think the Leroy Jenkins approach is appropriate.

PRICELESS!! lmao. @OP, awesome idea for the in dash flyer. Please post some completed pics!

have you thought about removing the camera from the back ad making "jumper cables" to put it up front? you might need something to make a housing for it to sit in the dash, but it would be better than writing a driver for it.

The thing is in adding(soldering?) 2 proper connectors to longer flex IMO, hard to do at home, but nothing is impossible. ^^
About OTG connecting - you'd probably use universal WebCam drivers from Ubuntu for eg. though the problem would be in powering that I think, WebCam has to be OTG compliant (with external power connector maybe?) or you'd need some special adapter, the rest is redirecting Android to use your webcam, but don't think it's hard comparing to other things.

I did this with a fascinate in my 87 BMW 325ic
I bought 2 extra cameras ( paid $16ea somewhere, cant remember off hand)
I failed at getting it to work myself as I suck at soldering.
However-
I had a friend take it into work and solder it in for me. We then took a light sensor from a 4th gen camaro , mounted it on my dash, ran the cam there, installed the phone and f-in-a . it was sweet.
this lasted for a full 3 weeks until something came undone and now the cam doesnt work. Ive switched back to the stock deck and just wired a bluetooth receiver into the tape deck, mounted a droid x down by the ashtray and it works. Not as great as what I had, but it works.
Point being, it can be done. and its pretty sweet when done right.

grab fried boards from ebay and start from there.

Wait some more weeks, cotula is developing usb host mode driver, and he has developed a working driver. Its for android. It will be available soon to public when he corrects the errors.
So u can simply plug in an usb cam to ur phone( providing only external power supplay is needed.) So u can do it with out bricking ur phone. Till then use it as a phone..

iPod Classic [USB C addon] [WIP]

This is in the concept stage. There are no guarantees.
I am converting my Ipod classic to use a series of SD cards, and I picked up a spare iPod for cheap. This is going to be my work log for removing the stock 30 pin connector and replacing it with a USB C connector. I'll need to design and 3d print the bottom cover of the device except where the connector is. I'm not even sure if there's enough room on the board for this to happen, I might end up needing to cut into the iPod board and do tracing stuff to make room.

One thing I'm wondering is if I can attach the firewire of the iPod to the firewire of the USB c port. I think I'll try to make a 30pin connector to USB C to test and see if there's any advantage before I attach anything to the board itself.

I have a 3d printer now, and the dev boards have arrived.

Please update your work log!
I thought I was the only one wishing to upgrade my port along with my other mods to my ipod. I'm curious as to how you did it and what steps you took to make it happen! Following for future updates.

Unfortunately I'm stuck. I've tried translating the pins from one to another, but nothing I've tried works. It does not recognize it.
If someone knows what pins to what to make the conversion, all I care about is making sure it can still charge and sync. Not the other 30 pin features.

Any updates to this?

Am wondering the same, has anyone else attempted this? Wonder if there's a QI adapter anywhere. Would love to get rid of the crappy charging cable it requires.

Great project any news

lets reignite this project !
Save the BS and simplify it, just 4 pins, "D+", "D-", "5V+" and "GND", these are all we need to charge and transfer data.
What was the road block here? just unable to obtain USB connection ? Type C is a little tricky as it has a parallel design like lightning. Maybe you had got the pinout jumbled or connected one side in reverse? Ordering some test boards and Type C port components to see what i can achieve!
https://www.theiphonewiki.com/wiki/30-pin_Connector
Someone else commented about QI charging, it is entirely possible and would not be very difficult to do, the only problem is the iPod has a solid metal back so it would need a custom manufactured back replacement. I absolutely love the idea but i dont think anyone has the money/time/resources to design, manufacture the parts required. Because even if they did they would be sitting on it for a very long time with very limited sales(not to mention how many different variations.)
