[Q] Transformer wont boot withou dock or usb

I'm having a problem with my transformer, it wont turn on withou being connected to the dock or usb to a computer...
I've tried to install another rom but it still keeps the problem.. What can i do?
I've updated to ICS, is there any way that this update is related to the problem? thanks
EDIT: Installing custom rom, downgrading back to HC and it still remains.. What can i do?

Does it work properly after its booted? I mean, can you disconnect it from the dock/PC?
My first thought was "busted battery", but that doesnt quite seem to fit...
You could try draining the battery completely in the tablet, then leave it charging over night (turned off, not connected to dock or PC) and see if that helps.

Sounds like a bad power button. After it turn on with USB or dock connection, does it still stay power on and operate normally?

Yes, its fully operational... I've tried to reset battery stats too...

Infuse USB Connection Issue

Recently we have been getting in stock i997's that are having USB issues connecting to the computer. As always we enable USB debugger and connect to the computer however now the units are going into charge mode a few seconds after connecting to the computer and shutting the device down. Once we disconnect the device from the computer it automatically restarts.
Here is what we have done so far with no luck:
-Enable USB debugging
-Disable USB debugging & enable mass storage
-*#7284# was set to USB=PDA, changed to Modem & back to PDA
-*#9090# Didn't see any relevant options
-Slightly bending the USB port
I don't think it is a hardware issue but a software issue that needs to be configured. Any help would be very much appreciated!!

USB
Get it as stock as you can with software. If the USB still does not connect correctly then it is a hardware issue. There was never a problem in any stock rom with USB connectivity.
Just my thoughts. It may not be the phone but the connection-- Computer, cable, oops,-- or drivers.

I'm facing the same problem !
I too have the same problem very weird tried several time stock have no issue in connection. this issue occur after few days not immediately and no regular pattern so can't say what's going on. right now my phone while put on charge shows charging but when un plug it still have 1% as charge no battery put to charge message shows up, tried with charger, usb to computer.
I also noticed before that charging stops and only come in effect when you pull the battery and plug the cable put the battery it will start the phone automatically and charge start up.
Can't ever put in charge in switch off mode as every time it automatically switch on my phone.
I tried several time these step 1. Go back to stock by heimdall , 2. heimdall kernal flash for red cwm, 3 wipe, format, fix permission 4. flash
couple of days work smoothly then problem reoccurs

Did you try mtp mode like with media player mode

Thanks RDomke for the reply.
We already flashed UCKD5 with no luck. Would there be anything else we could do? I agree that it may be hardware if stock doesn't work but we have been getting in too many units out of box with this issue. Not saying that it isn't possible to be hardware, just seems like it's something that could be software related.

SOLVED

RDomke,
Many thanks as we have solved the issue with your advise. The 1st unit we were testing did in fact have a bad usb port. Once properly diagnosed we tested another by flashing it back to stock and then performing a factory reset. Once done issue was solved and worked on many other with same issue.

USB OTG bug?

Hi, everyone.
im having this weird problem.
I use USB pen drive via OTG,
After i connect - use - disconnect, my tab fails to go in sleep mode. There is a battery drain as a result. Everything is fine, after i reboot the tab though, i mean the tab goes into sleep mode as soon as i turn off the screen. However, after using OTG, it fails to do so, even after closing the screen
Has anyone else, experience this prob?
Im on ICS, austrian Version. Ive noticed, this bug to be present in both the Austrian versions of ICS.
anyone has any clue as to what might be the cause?
thanks

USB issue

Hi, I'm having this issue with my Galaxy S6 (SM-G920F):
One day fast charging stopped working, but standard charge was working perfectly, OTG was working, Odin too. MTP wasn't working!
One day I plugged my phone at the wall, and it didn't show that it's charging, after some reboots it started charging well (not fast charging). Sometimes I have to wait 0% for charge it again, but if I use a PC instead of the wall adapter it works (sometimes not, but I just need to reboot it)! So I'm able to charge the phone only from a PC if the battery is not at 0%.
I checked if OTG and Odin are still working... MTP is not working, I can't event hear the USB plug-in sound from Windows, if I go in Odin mode, Windows says: "unknown USB device" and it won't work, I tried to reinstall drivers, but nothing.
So right now:
- Charging from the wall won't work well.
- Charging from a PC works better.
- Fast charging won't work.
- OTG is working.
- Odin is not working anymore.
- MTP is not working, PC doesn't find the mobile, I also can't hear the USB plug-in sound from Windows.
I tried different things: re-calibrate the battery, restore the stock firmware via Smart Switch, flash some ROMs... But nothing.
I can't understand why some days ago Odin and wall charging (not fast) were working but MTP wasn't, now none of thease are working.
The only thing that works well is OTG.
Right now I'm using OdexLite ROM with stock kernel, but I tried different ROMs, Samsung's stock included.

Hello
I have a same problem .
Please help.

check if in the setting there is an option: start manager, try to turn on MTP application.

I tried unsuccessfully to make my Fedora 24 and Fedora 25 detect the device, also tried on a MacOSX. It just charges, not only doesn't detect on download mode, as it doesn't even detect normally for file transfer etc.
Could it be an automatic update that killed MTP and fast charging? I've been searching the web for three days already searching for an alternative to flash/root or whatever to try to downgrade it and see if works with older version, but I couldn't. The device is 2yo, but is as new, I changed the battery and the connecting board on authorized service also with no good results. I hope I can make it work again! I appreciate any insight the community could have on this issue.
Cheers!

Question Android auto connectivity

Hi guys, tried to use android auto today for the first time and having absolutely no luck. Either with wireless or a cable. Car says device not recognized. I've rebooted both, deleted all devices off the cars system etc and still nothing. The phone connectsvia Bluetooth and takes calls and plays music no issue but android auto won't connect. When I plug the phone in via USB it says device not supported?
I've Googled and it seems this is a common issue. Does anyone know of a fix or having similar issues? I'm rooted so wondering is that the issue or could there be a workaround as I'm rooted instead perhaps. All suggestions welcome, thanks!
