Mega Download Mode - Samsung Galaxy Mega

I have a Galaxy Mega GT-I9205, which I have rooted and installed CWM recovery. I have had enormous problems in getting this phone into download mode with the stated key sequence of pressing Volume down, Home and Power simultaneously. It does work but probably only once in 40 tries, the other 39 times it just starts up normally and then has to be shut down before you can try again
I managed to find a different way to do this that works nearly every time and thought I would share it with you in case anyone else has the same problem, this is what you do.
Get your usb lead and plug it into your charger or a live usb socket on a computer. Plug the micro usb end into the phone and then without delay hold down the home and volume down buttons. Do not touch the power button. Keep these two buttons held down until the download mode warning screen appears (do not be tempted to let the buttons go when the phone vibrates to tell you it is connected to a power source or the method will fail). When you get the warning screen use the volume up button to confirm as per usual.
A couple of things I should say, there is absolutely nothing wrong with any of the buttons on my phone, they work perfectly in normal use, and secondly, I am not really a 'power user' when it comes to phones, I am more at home with computers, so this may be old news to you, but I have never read it before.
Hope this helps someone.

You could just install this Quick Boot (Reboot)

I also fail sometimes. Hold down vol down and home. Then press power and hold the three buttons until I see download mode. If I loosen any of the three keys too early, it may fail.

Download mode is Vol Down and Power only not the Home button as well.
Press both until the phone powers down and then you can release the power button but keep the Vol Down pressed until you see the warning screen.

And Recovery Mode is Power + Vol up (no home).
When we see a little blue line on top, pull up from Power but continue press the Vol up until Recovery arrive.

Whit "Quick Boot" we can go directly to Download Mode or to Recovery Mode. (no more Power + Vol xx)

Thanks for the replies. I discovered Quick Boot for myself, only today! It is certainly the best answer.
Sorry for not replying earlier, I subscribed to the thread, but got no notifications of replies, don't know why.
BTW Troute is absolutely right, Download mode is just power+Volume Down.
I got the 'home' key as well info from here: Edit Can't post outside links due forum rules, never mind.
Also
Code:
adb reboot bootloader
works as well (if you have adb on your computer).

Found a.convenient way to go into recovery or download mode a while ago:
Recovery : long press power button , select restart , confirm, put a finger near volume button, as soon as the phone vibrates, press vol up until booting recovery line shows up. The pressing must be quick and immediately after the vibration.
Download mode is the same as as above, only in the place of press vol up, do press vol down once and need not hold. Download mode shows immediately.

You can use Wanam Exposed module which has function of Power submenu. Tick Enable 4 way reboot menu option.

Can someone tell if triangle away works for Samsung Galaxy Mega 5.8 GT-I9152 or not ??

Can't get into download mode via button combination

My issue is as stated as above. I presume my phone has this feature disabled, making this phone near useless for me.
Tried having phone completely off and holding down volume down + home + power like in the videos, to no avail.
I've come from a Galaxy 3 which automatically started up download mode during the boot sequence.
Is there a way to root my phone without Odin or enter download mode with another method? Can't use "reboot download" in terminal as it's not rooted.
I haven't found any topics quite like my issue here. My phone is a international Galaxy III with label being exactly I9300. Any help is appreciated.
You could buy usb jig that will sort it iv never heard of this issue ever

Interesting, atleast there's something to fall back on if there are no other solutions.
Postage to New Zealand would be horrendous.
Please confirm it doesn't work in the following order.
- Make sure you have no case on the phone.
- Power off the phone
- Unplug it from the charger
- Remove the battery for 30 seconds
- Press and hold Volume-Down and center hardware button.
Make sure both buttons are proplery pressed, and the center button is pressed in the middle.
- Press the power button, and release it when the logo appears. Keep the other 2 buttons pressed
- Wait for it to boot
If it doesn't work, try repeating 2 times starting at the top.
If it still doesn't work something is faulty. Check if all the buttons work as expected.
Thank you very much d4fseeker, the battery out was the crucial thing I was doing wrong.
It shouldn't be necessary (and usually isn't) but I've seen on multiple occasions that Samsung phones sometimes don't react to the Download mode or Recovery mode when normally powered down.

Get out of "download mode"

This may be a noob type question, but how do I get out of "download mode" if I accidentally did the "volume down + home + power" trying to get into recovery? I've tried pressing buttons and even launched ODIN again to see if it had an obvious option to reboot (without downloading a file). I'm afraid to pull the battery unless I hear that it's okay to do so. Please help!
You can simply hold the power button for 5-8 seconds until the phone turn off. You can also do a battery pull, but only if you're not flashing anything.
If you don't have the usb cable plugged in. I don't think it will go into Download mode.
Remember to release the Power button after you feel the phone vibrate once.

You can go into download mode at any time.

Atrix boot loop

I got an Atrix from a friend who was having problems with it.
I tried turning it on and it stays tuck in a boot loop with the "Dual Core Technology" screen.
I tried a couple of key combinations to see if I could get to fastboot but nothing works. So far I've tried the following combinations:
1. holding the volume up button while powering on
2. holding the volume down button while powering on
3. holding volume up + volume down while putting the battery in and then pressing the power button
4. holding volume up + volume down while putting the battery in and then letting go of volume down and pressing the power button
5. holding power and volume up button while putting the battery in
I also tried this. After holding down the volume up button and pressing the power button, i tried hitting the volume down button once and then hitting volume up, hitting it twice and then volume up, 3 times and volume up, etc. etc. and then plugging in the phone to the computer, just in case the fastboot menu was there but I couldn't see it, but that doesn't seem to work either.
As it stands right now, all I'm getting is the boot loop. The phone had been sitting around for a while so I'm not really sure what the history is so all I have to go off of is what I have in front of me.
I'd appreciate any help in the matter.
Can you tell more history of the phone?
Is it rooted?
Is the bootloader unlocked?
Which ROM is it running if it's running one?

I'm pretty sure its not rooted and almost certain its the stock rom but I have no idea about the bootloader. My friend is not very tech-savy so I'm guessing that the bootloader is locked.
I have no way to verify any of this. All I have at this point is the phone that sits looping at the "dual core technology" screen.
If you have any ideas about which way to proceed from here, I'd greatly appreciate it!
What exactly is happening (down to the last detail) when you boot while holding Vol(-)?

When I have the volume down button pressed while booting, the green led stays on for 4-5 seconds, then the phone boots to the dual core screen, it'll stay there for about 5-7 seconds, then go to the M logo with the ripples and then the screen goes black for a second and then it loops back to the dual core screen. Only, this time, there is no delay between the 'dual core technology' screen and the M logo with the ripples.
Try this:
1) Remove battery
2) Replace battery while holding volume down button
3) Navigate to recovery
Should get you out of the loop.

Maybe the easiest way to get make it work again would be to flash the original stock rom with RSDLite.
It's very easy, you just need to connect your phone via fastboot ( when powering on hold vol(-) key until it says fastboot), then press vol(+) and the computer will detect it.
Just remember to flash the correcto sbf for your phone, otherwise you will have another bootloop.

Where do I get the stock rom?
How about you do some searching on your own for a change?
This time search for fruitcakes. That's the stock ROM.

GApps error after installing Phone no longer starts.

Hi all.
I have a phone Samsung 920I not "L"
OK to start from the beginning. I am new to this and followed steps from watching Channel48 on YouTube. Not blaming him it's just so you have an Idia of where I got my info from.
Instlled Odin
I installed twrp-3.1.0-0-zeroflte.img and it didn't work.
I then found twrp-3.3.1-0-zeroflte.img and installed it over the top, Now works when booting into recovery.
I then installed 920F Samsung recover file that was only about 25Mb in size and got my phone working again.
left it for a day then tried again.
Installed twrp-3.3.1-0-zeroflte.img with Oden. works
Installed: EvolutionX_4.1.69_zerofltexx-10.0-20200331-0232-OFFICIAL Works I was happy Looked at "About" and it now says my phone is 920F :/ Andoird 10 cool it works so who cares if it says 920F right!!!
I then booted back into Recovery and Installed: open_gapps-arm64-10.0-pico-20200228 and that said it successfully installed and I swiped to restart the phone.
My phone powered off and that's where this ends.
I have tried holding the power button for about 30sec and nothing happens I tried plugging into the charger and it doesn't respond to show it's charging
Is there something I can do now or is the phone dead This is my main phone as I love the Samsung S6 over the rest because it has the main buttons, not on touchscreen and IR so I can use the phone as a remote.
Thanks
edit. update
I got my phone working again. I will leave this thread incase someone else asks the same thing.
How I got my phone to work again. This is what I found on Google search and I will BOLD the option that turned my phone on.
Press and hold Power button for more than 20 seconds to check whether it turns on your phone or not.
Press and hold Volume Up button for a few seconds and without releasing the Volume up button, press and hold Power button until your screen displays something.
Press and hold Volume Up button for a few seconds and without releasing the Volume up button, press and hold the Power + Home buttons until your screen displays something.
Press and hold Volume Down button for a few seconds, without releasing the Volume down button, press and hold Power button (totally 2 buttons) until your screen displays something.
Press and hold Volume Down button for a few seconds and without releasing the Volume down button, press and hold Power button + Home button until your screen displays something.

bricked chinese tablet

i have this tablet which i think is bricked, it wont turn on even if i hold down volume up or down. when I connect it to the pc, after 30/60 seconds the com port appears (screenshot), after 1 second it disappears and continues like this. would anyone know what to do? flash a firmware? in the screenshots there are all the information of the motherboard
similar issues i had with my chinese tablets. The core issue i figured was that they don't hold charge any more and the battery drops like 20-40% with every restart. so the best way to get this up back is to put it on charge for few hours. then hold the vol up + power button, you should see the recovery mode/options page where when you press vol up button you can choose between 3 options of recovery, fastboot, normal. keep presessing vol up and go to normal and then press vol down to reboot into normal mode. if you have a different battery to replace, start there. Good Luck!
