I can't go to download mode or recovery mode . It scews me
if you have no way into download mode your screwed. Look for different ways into download mode and see if you can get it

If you forsure cant get into download mode ask T-Mobile for a exchange. It is very easy to complete and since it happened after an official update you should have no issues completing the exchange
try pullin battery. plug phone into computer. hold volume up and volume down. put battery in. prest-o change-o you should see an android w/exclamation point in a triangle. if this fails a jig from skorpion(I believe that is his name) might help, just fyi ur vibe is probably 99% un-brickable.
Try to connect ur phone to pc & if you' ve seen an icon phone+pc+!, your in download mode..odin can read it..or you can simultaneously hold vol up + power to get into download mode

Odin COM POrt detection

Hey Guys, Im sorry for the newbie question but I have a Samsung galaxy S4 thats stuck on the ATT logo and Im trying to reload the phones stock ROM onto it.
Ive gone through and wiped out all the cache and set it back to factory settings but that hasnt worked. So Now I have found my stock rom to upload it and ODIN cant communicate with it with the phone in download mode.
I can get into Recovery mode also but for whatever reason, I cant get ODIN to communicate to it.
Any help is appreciated.
You need to install the Samsung usb drivers

If you're on Windows the drivers should automatically install. Also make sure its download mode that you're booting into. Hold Volume down and power button while the device is off and press volume up when a screen appears. Happy Odin flashing

Samsung Galaxy Grand 2 SM-G7102 not charging and turn on

PLEASE HELP me. i just charging my samsung grand 2 sm-g7102 and the downloading mode was appeared and after that my phone not charging and turn on. what can i do for this problem ? thanks in advance!
Hello..
That sound pretty wierd but can u enter recovery or download mode manually by pressing vol +-, home and power button? If not... Then I would recommend you to claim for a warranty ( if applicable ).
Might be hardware problem.

you need to flash your phone by Odin in pc
and try to flash a recovery first
just start Odin and select the zip file then connect your phone to the pc and see if the phone is detected
if it's not then maybe your phone is hard braked that time you need jtag and search about the problem more in xda

Problem solved, may be deleted

I was flashing an .Tar file(complete BTU)
Half during the flash the cable moved a little bit(USB still connect) but I heard the sound off disconnecting...
So the phone has a half flash and doesn't take new Odin flash.
I am now using Kies, phone goes directly in a kind of recovery screen and Kies is trying to connect (then I can use emergency flash)
But the problem is: it is still in connecting.....
Anybody got an idea?
