Sometimes download mode can work even if the screen isn't turning on. You should follow the instructions for download mode and see if Odin recognizes your phone.
if see odin has recognized ur fone, flash it with the stock firmware using odin!
Thanks for the response but I tried several times but phone is not booting up in downloading mode.

Try this (it may or may not work)
Launch PC Odin & get rom ready (I recommend LiteningRom [NB, it is custom rom that can be flashed via Odin]
turn ph off & remove battery...
plug ph into pc (NB, battery still out...)
**now you may need extra set of hands here (I managed it by myself though)**
now, hold the button combo to get ph in to d/l mode...
keeping the d/l button combo depressed... put battery back into ph...
hopefully ph will show d/l mode ready on screen & it will be seen by Odin :fingers-crossed:
(if above worked) flash Litening Rom & count your lucky stars...
NB, this saved me when my S2 had BSOD.... i.e. nothing showed on screen after flashing a recommended kernel (by a more experienced user/member - not the OP)
always read up before doing anything kernel/recovery related
Try USB jig.

[Q] Samsung Galaxy S Plus cannot go to recovery and download mode

Hello Guys. I own a Samsung galaxy s plus(GT-i9001), rooted and running cynogenmod ics by ivendor. My phone works fine before before i installed swapper 2 memory swap. I followed the instruction on this link http://forum.xda-developers.com/showthread.php?t=1445543 . Then when i rebooted my phone the problem happens. My phone do not reboot anymore, i can't go to recovery mode and download mode. It's completely paperweight. Even if i connect a charger, no battery charging status display on the screen. I've searched the internet and found the same problem from others who intalled swapper 2.I removed the battery and re insert it but nothing happens. My theory about this problem is the bootloader affected by manipulation of swapper 2 in /dev/block/mmcblk0p2.. but i dont have any solution....i can't use odin just because i can't go to download mode .............:crying::crying::crying::crying::crying::crying: . . Any solution for me to go to download mode and install a fresh rom????? Please help me. Thank you.

[Q] My Galaxy Mega Doesn't Work! Help!

Hello everyone.
My phone: Samsung Galaxy Mega 6.3
Today I decided to install CM11 on my phone. When I try to install recovery with Odin it was succesfully but when the phone restarts "set warranty bit recovery "
I researched this problem on the internet, someone writed If I reinstall the original ROM (from sammobile.com) the problem would be solved.
But it was worse. Because now the phone doesnt turn on. recovery mode and downloading mode doesnt working.
How can I recover the phone please help me. If you tell us step by step..

Hi..what model is your mega and which recovery did you use and were did you get the recovery from as the yellow warranty means that knox security is on you phone and any custom recoveries or custon roms will show this..but first have to find what model your phone is and which recovery was used.

samething happened to me, but its not broken, something just happens to where you cant see the boot logo picture anymore but the backlight still comes on.
try this.
when turning on your phone go through the steps to get to download mode
then plug it into your computer you should hear it connect.
if not you dont hear the connection then either your computer volume isnt up or you
didnt follow all of the steps to enter download mode correctly.
once youve gotten to download mode flash PHILZ CWM recovery for the i9200
then reboot
when turning on your phone go through the steps to get to recovery, the phone will stay on a black screen until you reach recovery.
wipe data & factory reset.
you should be fine afterwards. although you'll still have a black screen on boot up. just install a custom/stock rom
hope this helped
Thanks a lot for answers. I solved this problem. It was a screen problem and i changed screen of my phone. The phone is working perfect with official samsung Gt-i9200 rom which is published for Russia 4.4.2..

Galaxy S3 stuck on bootscreen (can't access recovery mode)

Hi, today I tried to downgrade my Galaxy S3 from Cyanogen 12 to stock firmware (So from Lollipop to Jellybean) but now it's stuck on the bootsceen and I can't access the recovery mode, I can just access download mode.
Hi Hencick - Welcome to XDA.
I'll just naturally assume that you're familiar with flashing roms...
Were you running a custom kernel with CM?
Can you access adb functions with a pc?
I have a similar problem on my phone I discovered today. I just get the Samsung logo on screen, it goes off, then comes back (bootloader loop i guess).
It was just sitting on charge. It hasn't done anything for a while other than updates, now when I come to it, it's like this.
I can't get into recovery mode, adb mode, download mode or anything. Just the Samsung logo flashing up, then going and coming back up.
Is this recoverable?
As it it keeps powering up, then off, then back up I'm not even sure I can use Odin on it.
TIA.
Edit: Ok, I can get it into download mode it seems. Only, now I'm not sure what to do! lol

Rom i9100 in i9100T, does not leave the bootloader !! without recovery mode or downlo

Hello friends, my son has a i9100T, yesterday left a friend it change the rom, but he put the i9100 rom, and now the mobile phone is in direct bootloader screen and never leaves it. Does not go into recovery mode or in download mode, I need help I can do to fix it?
Sure you can't boot into recovery or download?
The way I see it, a USB Jig might help.
