[Q] Hardware Locked Problem. paypal winning answer!

I have a hardware locked vibrant. I cannot access recovery with my vol + / - buttons however I have found a way to enter download mode almost 100%
1. power off phone
2. While phone is powering off plug in power cable
3. hold -/+ volume
4. the phone enters d/l mode as soon as the charge connects
DOWNLOAD MODE!!!
but my question is. Is download mode sufficient enough for modding/romming my phone? Is access to Recovery needed or very important? Seeing as I can enter recovery with clockwork.

and how do you get out of dl mode? what happens if you get that pc and triangle screen? how will you put it to dl mode again with locked vibrant?
If you can get into dl mode you can get into recovery. Hardware locked means just that. They use the same key combo but different timing.
EDIT: nvm... I can't read lol.
I just pull battery to get out of d/l mode, however, recovery mode has not been obtainable. Regardless of which method i try. I have tried over 200+ times trying to get into recovery so im really confused. Think its safe to still Mod/Rom with only a d/l mode..
so if i can get into download mode. i should be able to get into recovery? because i can't get this damn to get into recovery via hardware buttons. but download works everytime
call tmobile, tell them your phone is defective (cant access boot recovery)... they will send you a replacement phone... profit
(i know, i did this)

I have this same problem...
You should be fine with just dl mode, tho most roms will be flashed trough recovery. In your case, I would keep your phone. You risk Tmo sending you a completely hw locked phone.
To get into recovery, you still have 2 options:
Rom Manager if your phone works fine or
'adb reboot recovery' in adb if you happen to get a boot loop (this is hit or miss)
If you happen to get the phone!computer screen while ODIN-flashing, dl mode is more than sufficient to restore... hope this helps
I wouldnt start flashing without recovery. I had the same issue and returned the phone. If you don't want to return it, you can always use odin to flash with download mode, but clockwork is much, much more convenient. Like I said tho, I would return it. The phone is defective.
If you can get to DL mode.. install Odin and flash to stock.. Get phone rooted.. Install ROM manager and flash any rom you want and your done.. A lot of users probelm is to get into DL mode.. but if you can get to it.. you shoul have not any problem falshing another ROM..
Download mode is the more important of the two.
If something goes horribly wrong, Download can save you where nothing else can.
As others have stated, as long as your phone is functional, you can always adb reboot recovery and get into the recovery menu to do whatever you need to ['adb reboot download' works as well, but if your phone isn't functional, you can access it]
yeah i bought my phone off CList. The phone has no warranty w/ Tmobile. But after calling Samsung warranty (AKA INDIA) I had to cause a fit and ask for a supervisor. they gave me a shipping label and said they would "Reflash" my phone. Is the issue with entering recovery mode = a software issue or hardware issue?. Now im reluctant in sending in my device because they may send me another locked one.
BTW thanks for all the info.
Both my phones (original then new waranteed) have the same issue. I flash roms/etc. but I am VERY careful when I do it...HW locked phones suck, and T-Mobile says it is not a defect--in essence, they said that function doesn't exist to them.
...riiiiiiight.

[SOLVED] Can't get to download mode

Hey guys,
I've been dealing with a few unrelated problems that lead to try flashing a different bootloader onto my phone. Now that I've done this, I cannot get into download mode at all. The usual button presses do nothing and I even tried the AIO Vibrant Toolbox, but selecting the option for download mode simply reboots the phone and does nothing.
At this point, I simply want to go back to stock, but I'm not sure how to do that without being able to go into download mode and using odin. I am currently able to boot up into my rom and even boot the recovery manager as well. Is there anything I can do at this point?
Just for starters, I'm sure this is silly of me to ask. But just for verification, you know that GB boot loader has a diff button combo to get to download mode right?
Press and hold volume up + power button. This would give you yellow download icon. Then you'd plug in USB cable.
Actually, it seems I asked the foolish question, as you were exactly right!
I've been mistaken about my BL for a long time it seems, I thought that the this method was the old way, not the new one.
In any case, thank you so much.
Glad I could help.
wow thank u guys, i made the same dumb mistake and was trying all these complicated forms of fixing it. Passed up simplicity.

Can't boot into recovery, stuck at samsung logo

I'm trying to fix a friend's note(sgh-i717r) and it won't boot into recovery. When pressing the button combo, it just keeps vibrating and when I let go it's stuck on the samsung logo. I can still go into download mode and flash different custom recoveries or firmwares with odin but I can't get past the samsung logo.
I'd really appreciate some advice because my friend can't even use his phone at all until then.
Is your power button getting stuck? ?
This problem is very common ...and the device just loops ...g
I don't think so since I can get into download mode without problems
What button combo are you using? Make sure you let go of the power button after the first vibration and continue to hold volume up and down or it will keep vibrating.

With the right combo...even a device that is stuck, is not really stuck, as the same combo will boot you to either the recovery, or the DL mode.....
Are you sure that recovery is present ??
You did mention that a flash of recovery was successful, but have you seen it ??....as it may have failed, even though odin says "pass"....g

For download mode I use power + vol down, and recovery I use power + vol up + vol down and after the first vibrate I let go of everything except vol up. I was able to enter into recovery before trying to flash superuser but now it's stuck.

The recovery is there as I used it to try and flash superuser but it gave me an error about an incorrect md5(and I know it shouldn't be giving that problem because I used the superuser file from the stickies that the majority of people had no problems with) so I tried using the latest version of twrp instead of cwm.
Well...
I suggest you go into download mode, and push a factory image to the device via Odin, and start over completely...
It's looking like the device has a bad recovery image, but if DL mode is still there, you are able to save it by a restore.....
Go into the super thread at the top of the general section, and scroll down the first post to the restore area, and you will find the links and instructions to put the device back to stock, and re-root....
At least that way, you know where you started from, and the device will get cleaned out for a fresh try again....g

[Q] Is this a Brick? What should I do?

I recently sold my og note to a friend. it was rooted running black star. He has asked me to try and fix it for him because it will not boot up. when he gave it to me it was stuck at the download mode warning screen ("volume up : Continue ; volume down : Cancel (restart phone)") . I was able to get it into recovery . I tried to flash a few different roms i had on the phone when i gave it to him. I was able to flash a rom and get a successful message but then it would not start it would just go back to the warning screen. I then tried to use odin to flash stock rom but it wont go past the warning screen. pressing up or down doesnt do anything. the only thing it will do from there is boot into recovery mode. Does it sound like its bricked or should i try something else? anyhelp would be greatly appreciated.
thanks
matt
Sounds like the volume down button is stuck. When you reboot if you hold volume down with power it takes you to that screen. Pull the battery and see if you can free the button.
Agreed ....the device is not bricked ....g
Or friend deleted OS files and it can't boot. Worst case is you connect to a pc and Odin or Kies flash a new system.

download, unzip the downloaded file until u get a tar.md5 file
got o recovery and wipe data/factory reset (and format system, preload, data and cache if on a custom recovery, check under mount and storage)
reboot to download mode, plug your phone
open odin, click pda, select the tar.md5 file, hit start and wait.
if the phone does boot after flashing, wait a minute, reboot to recovery, wipe data/factory reset and reboot (even if the device boots at first time, i advise u to do this wipe anyway)
back working again, couldnt get into the recovery mode, tried the up volume home and power, also searched and tried the up down power also, all i want to do is unlock my phone lol

Keep trying that combo, do it while the device is off, press it till you get there.
And why the hell do you want to get into recovery in order to unlock the phone?
Sent from the little guy
the guy above recommended i go to recovery and delete all data, so thats what i was trying to do, he also helped get my phone back working, is it possible to unlock without rooting ?
Yes, by getting the unlock code from your carrier.
I suggest you read a couple of threads before you attempt rooting it.
