Download Mode and bootloader - Samsung Galaxy Mega

Hi guys! I've been having problems with my Mega. My phone works really fine. I just got it the other day. But whenever I try to go to download mode or recovery I only get a blank screen but I know that it goes to download or recovery because my phone could detect it. I've been reading some forums that I have to reflash the bootloader of my phone so I could fix that error. Does anyone here confirm this and could anyone provide me a flashabble copy of the bootloader? Thanks!
Here's what I found on the other forums:
makeyourself said:
Your problem sounds similar to this one. I assume when you say 'blank screen' that the screen is powered on?
Power off the phone, hold down VolUp + VolDown + Power for 4 to 5 seconds. Then release ALL AT THE SAME TIME. Now press Volume Up. Now hopefully you will be in download mode even if you can't see that you are. If it doesn't work try it again a couple of times. The reason that you have to press Volume Up is that a warning screen is actually displayed before the phone lets you into download mode.
The phone will give you no other indication that its in download mode and won't 'recognise Odin' when not in download mode. Make sure you have Samsung USB drivers (comes with Samsung Kies) installed on your PC.
Oh yeah and by the way the thread I've linked to suggests you have to reflash the bootloader to fix the 'blank screen' problem.

Could anyone help me out on this one? Thanks

Is this a question with answer? That's a first lol.
Glad you sorted the problem.

This is a question. I need to get the bootloader..
Another question, if I flash the stock rom will it also fix the bootloader? And is it safe to flash with this kind of problem like with the blank screen (but the computer could detect the phone is in the download mode)

If you can get to bootloader and ODIN recognises the device then it is worth a try, can you get to recovery to backup first?

Can't use recovery to backup. I was still using the original recovery not cwm. But i finally flashed a rom on my phone but it still has the blank screen. Atleast I'm not scred anymore that my download manager is not working

[q] samsung vibrant overstock kernel problem

im having a problem getting into my vibrant phone.... i tried switching to one of the newest overstock kernel roms i followed each step i think and when i want to reboot my phone the only thing that shows up is the samsung vibrant logo and overstock logo over and over again.... i tried to go back into recovery mode but i cant.... so is my phone bricked or is there any other way i can get into recovery mode to get it running again?
Did you try to attach one end of the USB cable to your vibrant while holding down both the volume buttons then insert the other end to the PC?
This should get you to download mode.

I havent tried the usb from the pc yet.... Will it work with macs???
if can't get into recovery without the 3rd button combo, is possible that you phone is hardware locked and probably can't get into download mode. This is just a tip for you and some other people trying new ROMS/KERNELS, do some research on your phone before trying anything on it, such as getting the phone in download mode, using odin/heimdall, remember that by rooting your phone you voided your warranty.

Odin wont work on mac so you wont be able to flash to stock using that but you could try this way to check if your phone really is bricked or not. Then you can try it out on windows and flash to stock if you were indeed able to enter download mode.

You can use Heimdall. I don't think it allows repartitioning, but you can definitely flash back to stock with it. See this thread.
Thanks im gonna try this out.... hope it works
So you can't get to recovery with buttons?
Have you tried:
1. Hold both volume buttons
2. Power on phone (no USB cable attached)
3. Release power button at first Vibrant screen (keep holding volume buttons)

[Q] My Sgh i777 can't enter in download mode eighter in recovery mode

Well, my phone cant enter in this modes, but the problem its that also cant enter to the system, i can only see the logo of samsung and then the screen turn off, I dont know what to do, because I cant use the odin because I cant enter in download mode, I dont know if there is a button to hard reset the phone. I was trying to put a rom of ics but i believe that the firmware was wrong for my phone. please help me.
Sounds like you flashed something in Odin that was not for your phone. You probably need to get it J-tagged to get it fixed. Check out mobiletechvideos.com
It's like $50 dollars for the service, they'll J-tag your phone and flash the correct bootloader.

Thanks for your fast answer Mattix but you don't know another way to fix it, because I'm not in United States then its very dificult ( and take to much time ) to send my phone.

Since the phone will turn on, and initiate the boot process, it should be able to recover it yourself. Jtag is for true hard bricks, which your phone is NOT.
Please give a full description of what led up to your problem. What firmware was on the phone before, what did you attempt to flash, and anything that you can think of that would provide any additional information for trouble shooting. Also, a link to the firmware you tried to flash.

To get the SGH-I777 into download mode, continuously hold down both volume buttons (but not the power button) while plugging in the usb cable.
Can you answer my previous question?

Nobody knows what can I do in that moment?
I put my i777 on download mode by removing the battery and putting it back. Hold the volume button down and connect the USB charger wait for the buttons to flash and disconnect the charger while holding the volume down button. If that doesn't work nothing will.

Try this:
Pull the battery and leave it out.
Hold down volume button and plug in the USB cable. (PC will supply the power)
This should boot the phone into download mode.
If the above works to get into download mode, do the following:
Download the I777 secondary bootloader .tar from the Download Repository. See the link in my signature.
Unplug the phone (to shut off)
Open Odin v1.85 on screen of pc.
Enter download mode as above.
When connected put the secondary bootloader in the PDA slot in Odin and flash.

I just recently got my SGS2 (i777) and decided to root it. Unfortunately I got the root from another site (dumb move) and today the phone went into a reboot loop. I can connect it and get it into download mode, but everytime I try to flash back to the stock rom, or anything else (bootloader) Odin says connection failed, unable to open COM Port. I know it connects because it installs the drivers for the phone. Can someone MUCH smarter that me assist with this one?

can you interrupt the bootloop by trying to get to recovery (holding VOL UP + VOL DOWN + POWER until recovery menu appears) and then go to backup-restore and restore a backup? That's what I would try. IF that does not work, I would reinstall the drivers for andoid on your pc --even though you had them working (presumably) once before. After reinstalling the drivers then odin should (may!) see the phone and work.
good luck

Need Help! SGS3 stuck at boot logo.

If you flash a official release from sammobile it should not increase your binary count, thus leaving your warranty intact. It is when you root or flash a custom Rom your binary will increase.
Worst case you need to use triangleaway if counter increases
Sent from my Jelly Omega SIII using XDA App
If anyone's interested, I had to return the phone under warranty where they replaced the main PBA.
The combination to get to recovery is this (for future reference)
Vol-up + home + power button. Once galaxy s 3 logo pops up quickly let go of the power button and hold in again then let all three go once in recovery.

You guy´s soft bricked your phones thats why u dont get any where re-flashing, but heres something worth trying without risking anything!!
---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
JUST GET YOUR SAMMY STOCK ROM FIRST FROM THEIR SITE
Use this Odin version >android.gs/download-odin-1-85/.
Above the country code and you can know the three-letter code which applies to your country. Now look for the date of release and select an appropriate update release for your phone.
Step-4 Rebooting
Reboot by holding Home, Volume Down and Power buttons. Remember you need to hold the Volume Down button and not the Volume Up button as in the first step. You will get into the download mode. So, you phone is now ready to get the firmware via USB.
The phone will flash a warning about the dangers involved. You should not worry as you are putting the firmware back on the phone.
On the computer, now unzip the Samsung firmware folder you downloaded from the official website. Now extract the .md5 file.
Now open Odin, select.md5 file in the 'PDA' section of Odin.
Make sure that Auto Reboot and F. Reset Time is ticked.
Connect your Galaxy S3 to your computer via the USB lead. Odin will automatically detect the phone and a pop-up message will show. Now start the process of transferring the file.
Step-5
Wait for the file to download. Odin will show 'PASS!' in the box once the transfer is successful. And the phone will then, reboot.
If it hangs on the Samsung logo, don't worry reboot into the recovery mode by holding down Home, Volume Up and Power buttons. Wipe the data/factory reset and reboot.
This will in all chances bring your phone to a functioning mode. Sign in and start working.
--------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
The extent of you phone being bricked may vary, but the symptoms are often the same -- a reboot loop, switching itself off after the Samsung logo or never getting into the operating system. As long as you can get into the recovery mode, there is hope to recover the Samsung Galaxy S3,
no success
Hi guys,
your solutions are great but in my case it didnt help at all.
My phone still stucks at logo. Only download mode is possible, but odin wanted a pit file always when i tried to download the sammy firmware rom. After all i even downloaded the pit file GT-I9300_mx_20120329.pit. But even with the pitfile and Re-Partitioning it didnt function at all.
My SGS3 T-Mobile can not start at all.
PLEASE HELP ME, i am helpless.

You gotta get into download mode somehow either with computer and Odin or through different button combination on device try Heimdall as well might be able to use that but if you can't get into bootloader or recovery then it's a wrap

Yes, do as UncleLester has said. Try hold volume down + power for 10+ seconds. If you're able to go into download mode, you can restore to stock. If the phone doesn't turn on at all, I'm not sure what else you can do...
yeah, I held down the volume up + down + power for almost a minute. Nothing :/
I'm with jpark623 with that if none of the above work I'm afraid your a bit stuck.
What device is it by the way? And how did you get into this mess?
Sent from my LT26i using xda app-developers app
Download mode is accessible by volume down + power. Recovery mode is volume down + volume up + power. Don't press volume up for download mode.
My phone is not even recognized in the ID:COM Section
Were you able to access download mode? If so, then you need to install drivers. If not, you NEED to be in download mode.

There is a thread with a link to a Flashtool download or do what I done and Google Odin and download that.
Odin and Flashtool are programs that make flashing a little easier, the device needs to be put in a fastboot/flash/recovery mode (depending on device it's usually a combo of volume up + volume down or sometimes including the home button) when it's in it, Odin or Flashtool will detect it thats when you can select your chosen Rom.
I use Odin more than Flashtool just because I came across it first and it's never let me down however I haven't used it in a while, when I downloaded it though it did have a little 'how to' guide so everything you need to know will be im there.
Hope this helped if so click that 'Thanks' button

I was trying out different custom roms that I had downloaded. I had just finished one and decided to change it. After booting it into recovery mode, I had wiped the cache and reset it back to factory settings. I tried to load a roam named "JZO54K.N7000XXLS7". It errored and stopped trying to install. Afterwards I ended up wiping it again and resetting the cache to make sure there were no remnants. Following this, I rebooted the phone and now i'm in this position

From just reading that I think your device has had it, if your getting no response from those combos them I doubt the computer will read it as it wont have power.
Sorry chum bad times

There is a thread with a link to a Flashtool download or do what I done and Google Odin and download that.
Odin and Flashtool are programs that make flashing a little easier, the device needs to be put in a fastboot/flash/recovery mode (depending on device it's usually a combo of volume up + volume down or sometimes including the home button) when it's in it, Odin or Flashtool will detect it thats when you can select your chosen Rom.
I use Odin more than Flashtool just because I came across it first and it's never let me down however I haven't used it in a while, when I downloaded it though it did have a little 'how to' guide so everything you need to know will be im there.
Hope this helped if so click that 'Thanks' button

It seems that i'm not even able to even get into recovery or download mode as it is a blank screen, no matter how long I hold down the buttons for.
Sounds like you somehow hard bricked your phone... Not sure how you can recover your phone without professional help. Sorry I couldn't help.
I had only just got this phone a day ago :/

[Q] Samsung Galaxy S2 GT-I9100 flashed wrong kernel???

I have a Samsung Galaxy S2 GT-I9100 that I recently rooted and when I rooted it it flashed a custom Kernel as well. Upon rebooting the phone, now my home button and back button soft key is not responding. I think I may have flashed a kernel from one of the Galaxy S2s that has the 4 soft keys along the bottom rather than the 2 soft keys and the home button, Whenever I try to flash anything through Odin now it says that a connection failure happens. If I put the phone into Download mode it is not recognized through Odin anymore either. Also, when I plug the phone into the USB of my computer and try to do anything with the phone through the USB it shuts it off and just shows the battery charging symbol. If I try to flash anything through recovery it says that Signature verification failed. I'm a bit stuck and I don't know what else to try.

Try another usb port/usb cable/pc.
If it sees you phone, don't forget to close all kies applications (if you don't have kies, download it!)

If you can acces recovery mode (Volume UP+Home+Power) you can save yourself:
-If you can't access the SD card by USB, try to remove your external SD card and connect it to PC through a card reader, if you don't have one, buy it because it's far cheaper than an new SGS2 (or 3)
-Download Phil'z kernel that suits your current ROM and copy it to your SD card
-Put SD card back into phone and flash this kernel (See post #3 of the above thread), depending on what kernel you have flashed, read the appropriate instructions (usually: Install Zip from SD Card > Choose Zip from SD card > select and apply)
-You are done :laugh:
BTW, can you provide a link to the kernel you flashed ?
Hope this helps
I have tried that. Everything I try to flash through recovery it says "signature failure" or something along those lines.

Put your phone in download mode and flash philz kernel by downloading the tar and flashing through odin

Signature check error means that you are trying to flash a custom kernel (I may be wrong) on non rooted phone
Philz kernel could bypass this
Have you tried cwm flashable philz kernel ??

Download mode is available, but when I plug it into the USB port Odin won't recognize it. But all of the drivers are installed. I've tried to flash philz through Odin but it won't recognize my device as being plugged in unless the phone is actually booted into Android OS. Then when I try to flash it just shuts the phone off and pops up the battery charging image.

Regardless of what it says there, what does it say for model on the label under the battery?

It says GT-I900.
But everything worked fine, then I flashed that file through ODIN and ever since the home button and the back button soft key wont recognize. So I'm pretty sure whatever I flashed was for the Galaxy S2 model with the four soft keys rather than just the two with a home button.
So flash another kernel for I9100.
Get it at xda tho.

I've been trying. Odin won't recognize my device when in Download mode, when i boot into Android and try to do anything through USB it shuts down to the battery charging logo, through recovery I get "signature verification failure" all of these suggestions are helpful, but I have already tried them.

Try keep phone and pc linked through USB cable and restart the phone in download mode.

Try all usb ports, usb cable and / or another pc / laptop.

Hi
Have u tried flashing another kernel through mobile-odin ?
I'm still new to this stuff but I think it should work for you.
If u want to try it look for the thread with same name dl it ..free version, you will also need another file in same thread called
MobileODIN_FlashKernel_I9100-v2.0 (in same thread further down)
you can dl them on pc, put on card install them try.
or try rom-customiser u should be able to flash a diff kernel or Rom without pc-odin or recovery mode.
Good luck
Peace
I tried keeping it connected and restarting it. I also tried stopping all Kies processes and that didn't work so I uninstalled it but kept the driver. That didn't work. So I tried reinstalling the drivers.

So you can get to DL mode right?
And you're sure It's a I9100 Model.
- You've re-installed kies already, so we good there. If you've unistalled it, please re-install again & close all 4 kies applications running on background.
- Get a couple of USB cables (along with the original I9100's cable) and start trying them one by one on each USB port.
- Still don't work? Try it out on another PC, same drill.
- No luck? Try the same steps in "Windoze".
- If all above fail, try it all again.
You gotta make that PC see your device, it already did, so it can do it again.
