[GUIDE] / [ FIX ] - Accessing downloader & recovery w/ locked hardware access

LET ME MAKE THIS VERY CLEAR - MOST OF YOU ALREADY KNOW HOW TO ACCESS DOWNLOAD MODE OR RECOVERY VIA HARDWARE BUTTONS....
BUT NEWER PHONES SEEM TO HAVE HARDWARE ACCESS DISABLED.. THIS IS A WORKAROUND FOR THESE LOCKED OUT PHONES...
THERE IS NOW A ODIN FLASHABLE FIX FOR H/W LOCKED PHONES
SEE THIS THREAD - THANK YOU untermensch
http://forum.xda-developers.com/showthread.php?t=804305
METHOD 1: ACCESSING DOWNLOADER/RECOVERY:
(if the following directions do not work... then your phone may be locked out from using hardware buttons to access downloader/recovery)
Download Mode:
With the phone powered off
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should say Downloading.
Recovery Mode:
With the phone powered off
UnPlug the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down
Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should be on the recovery screen.
METHOD 2: STUCK AT VIBRANT SCREEN:
(and are not able to use vol+ vol- methods to access downloader/recovery)
You will need the samsung ADB drivers installed for your phone as well as ADB...
ACCESS DOWNLOAD MODE
1) remove back cover and take our sim card and sd-card.
2) take out the battery
3) hold ALL 3 buttons down at the same time. (Vol +, Vol -, Power)
4) while holding down those 3 buttons put the battery back in
5) continue holding all 3 buttons until the vibrant disappears and reappears... once it reappears, release all 3 buttons
6) Setup ODIN and get it all setup and ready... (if you are flashing your phone via odin)
6) now connect your phone to your pc via USB cable
7) open a cmd prompt and navigate to the folder with ADB and type ADB REBOOT DOWNLOAD
8) Your phone will reboot into the download screen... go back to ODIN - A com port should now appear for your phone...
9) Click start and wait for your phone to do its thing
ACCESS STOCK RECOVERY
1) remove back cover and take our sim card and sd-card.
2) take out the battery
3) hold ALL 3 buttons down at the same time. (Vol +, Vol -, Power)
4) while holding down those 3 buttons put the battery back in
5) continue holding all 3 buttons until the vibrant disappears and reappears... once it reappears, release all 3 buttons
6) now connect your phone to your pc via USB cable
7) open a cmd prompt and navigate to the folder with ADB and type ADB REBOOT RECOVERY
8) Your phone will reboot into the stock recovery and flash whatever update.zip you need
METHOD 3: STUCK AT PHONE ! COMPUTER:
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold Vol Up and Vol Down
Press and hold the power button with your right index finger.
The screen will go black, continue holding.
The screen will come back on, you'll see the same Phone to Computer icon
Continue holding, the screen will go black
The screen will come back on, you should see "Vibrant" release the power button and you it should go into Downloading
METHOD 4: STUCK AT PHONE ! COMPUTER:
(and are not able to use vol+ vol- methods to access downloader/recovery)
CALL TMOBILE AND BEG FOR THEM TO REPLACE UR PHONE..
METHOD 5: ODIN ERROR - ODIN HANGTHANKS EUGENE363)
When you can't get into Download MOde....
assuming you just got a Hang in ODIN Flasher...
1. Un-plug usb from Phone ( But still plugged into the Computer )
2. Pull Battery
3. Let the Phone sit for 15 to 30 seconds
4. Plug in USB to Both Phone & PC if not already
5. Hold Both Volume Buttons
6. Put Battery in while still holding Volume Buttons.
My Phone is HW Locked as well, with a v1 board.
every-time I get odin hang, doing the above always results in letting me re-flash.

Interesting! I'll give it a try.

UPDATE: I have successfully reflashed my vibrant... now I will reinsert the SD card and SIM card... and back in business!!!
I am 100% positive my phone was a newer "locked" model... I was unable to access the downloader OR the stock recovery and out of frustration.. I figured out how to access ADB and reboot my phone into downloader or stock recovery!
Hope this works for everyone!
For those of you that just want to test this method out... it does not seem to work for me now that my phone boots past the vibrant screen.... this method only seems to work if you are STUCK at the vibrant screen...

I wonder if this will work for people that are stuck at the computer ! screen... I am unable to get to download mode or recovery with the vol. buttons. tried all the methods that i can find in the forum.

That sucks... give my method a try play around with it... follow the guide.... see if the computer ! screen flashes... if it flashes.. release all three buttons when the computer ! screen reappears and see if it shows up when you connect the USB cable and type adb devices

Oh, I don't have the problem. I'm just thinking if this will work for it. This is the main reason why i'm not messing with different roms/firmware until i can figure out a sure way to get into download if anything would to go wrong. As of right now, i'm just rooted and running Vibrant6. Will not go any further until i figure out the download mode on these newer batch.

This actually does not work for me. I have to 1) Pull the battery to make sure the phone is off, 2) Put it back in, 3) plug into USB, and immediately press and hold vol up/down.
Or ADB Reboot Download, but only sometimes.

If you are about to immediately press and hold up/down you are clearly not using a locked phone... and believe me.. this method works.... i tested it out about 10 different times trying to make the how to as easy as possible... if you are STUCK at the vibrant screen... how were you accessing ADB?
LIKE I SAID... This seems to only work for phones that wont boot past the VIBRANT screen.. My phone is locked out of hardware access to downloading mode and recovery... If you arent locked out of hardware access... then this would be a pretty irrelevant GUIDE..
Here is what makes me believe I am locked out of hardware access... when I follow any of the tutorials on how to access download mode... my phone just flashes and goes back to the vibrant screen... or back to the battery.... it NEVER does anything else...
can anyone confirm that that is what happens with "locked" phones?
I have seen a few posts... in this thread as well as the general Q & A thread .. regarding people having this exact same problem... and having to take their phone back to t-mo to swap it out..

Heh seems like a lot of work. Here's what I normally do and always get into the desired mode.
Download Mode:
With the phone powered off
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold (left thumb) Vol Up and (right thumb) Vol Down

Press and hold the power button with your right index finger til you see "Virbant" release the power button and it should be on the recovery screen.
Get to Download mode while displaying the Phone to Computer Icon"
Plug in the USB cable.
Turn the phone on it's side and use both thumbs to hold Vol Up and Vol Down
Press and hold the power button with your right index finger.
The screen will go black, continue holding.
The screen will come back on, you'll see the same Phone to Computer icon

The screen will come back on, you should see "Vibrant" release the power button and you it should go into Downloading

Yes... my method seems difficult... BUT IT IS ALSO FOR NEWER VIBRANT PHONES THAT CANNOT ACCESS DOWNLOAD OR RECOVERY VIA YOUR METHOD OR ANYONE ELSES METHOD... because t-moble disabled hardware access...

That is exactly what happens with my phone. Either reboots or goes to the battery screen.

Well hopefully between your method and mine.... nobody should have a problem accessing the downloader.... I have tried your method about 15 times with zero success accessing downloader or recovery... and I am pretty savvy... not sure what the differences are between our phones...

I just got new Vibrant and everything works fine. No need for any of that.....just have to hold volume buttons and release power button at the exact specific time with usb pluged in, phone goes straght to download mode.

RIP vibrant
just tried this method, and it didn't work for me. My Vibrant has the phone-!-computer error and it's the newer phone that doesn't load to recovery/dl mode via hard keys. I so happened to be loading a rom using odin and unplugged it because the process didn't show a status bar, it basically sat there doing nothing. Once i unplugged the phone it showed nothing but that error message on power up, hardreboot, charging ect. Thanks, tmo for locking hardkey recovery mode =(

had this happen twice and those steps worked for me both times:
"have your usb in, press down both the volume up/down toggle and the power button.... hold them until the screen goes black and as soon as it does, let go only the power button and it should appear there again
however, i found out that you need to take out the battery and get into download mode freshly again...."

This is exactly what I do on my phone. Actually had to do all three of this last weekend when I made a bonehead move and damn near bricked my phone. ODIN and Titanium backup saved my bacon.
I still do not fully understand this whole disabled recovery access thing. Has Samsung acknowledged it as a bug or a new permanent change? I heard they were going to fix it in the Froyo release?

I am unsure of what phones are locked and which ones arent... its kind of weird that some phones are locked out... my question for Eugene or JAC...
Is it possible to take an unlocked phone... and flash everything over to a locked phone... "unlocking it" so that the hardware buttons work?
and by unlocked I mean... able to access downloader/recovery via hardware buttons...
Those of you that ended up on the Phone ! Computer screen... if your phone is hardware locked... you are screwed... the method I originally posted only works if your phone will at least boot to the Vibrant screen (and have a hardware locked phone)
If your phone is not hardware locked... you can follow the millions of posts telling you how they access download mode... no need to follow my guide

Recently, I bricked my phone due to the hardware recovery/download feature being disabled.
Sitting here waiting (for 3 days) for the prepaid UPS return sticker from TMo I had a thought...
What if TMo/Samsung did not actually lock some of these phones down.
Follow along...
In the past, every single phone that I have ever owned would power up via USB connection (from the wall) even if the battery was not installed.
Tonight I noticed that my Vibrant will not power up unless the battery is installed.
USB (from PC) - Battery = No Power
USB (from wall) - Battery = No Power
Battery +/- USB (any) = Phone--!--PC icon
If someone who has a fully functional Vibrant (hardware recovery/download feature works) could try this out?
I'm curious to see if this is a possible pattern...

People keep saying to hold power in some way or another to get to download mode... You dont need to ever touch the power button!
Turn phone off, plug usb into computer, hold both volume buttons in and plug usb into phone. It will instantly go into download mode.

[Q] No really, I bricked it...

OK, I've been reading here for 6 days all manner of Captivate unbricking. Here is my story...
I picked up a Captivate on the Rogers network. I connected it to my email server (Exchange 2010) with no problems, poked around, noticed the lag, noticed the SMS time issue, then promptly rooted, installed clockwork, and then threw cognition 2.2 beta 9.1.3. Quite frankly I was shocked at how much faster it was.
Anyways, after a day of poking around, I could not get my email to my exchange server running (tried the email.pak floating about), so I actually decided I was going to go back to the backup I made of my phone using clockwork before I installed cognition. When I restored my backup, I thought I had bricked my phone.
I let it rest for a day, then came back here, and found one of the 3-4 different variations of the 4 button download mode combo that permitted me to do the 1 click restore. This restored me to the AT&T version of 2.1. It worked, but was less than desirable.
I decided that at that point I really wanted to go back to stock, so I downloaded the stock backup on the Rogers Captivate wiki page, and did the restore using clockwork. The phone has not been the same since.
When i turn it on, I get an at&t splash screen, then in about 20 seconds I get the at&t "jingle", but the splash screen stays on. I can't seem to find any key combination that will permit me to get back into download mode so I can restore using the One Click that worked for me the first time. I have tried:
1. 3 button salute with USB in first, battery out initially.
2. 3 button salute with USB plugged in *as* I was inserting the battery.
3. Power and volume down (both with and without USB, and with battery being plugged in after USB and "during" insertion of battery)
4.Power and volume up with same combo's as #3.
5. Just volume up and volume down with same combo's as #3.
In all cases Odin was running before USB connected, running as administrator. I'm running 64bit windows, but I'm sure I have the correct drivers because I did this the first time with Odin and download mode and I haven't added or changed anything. But just for arguements sake I did uninstall, and then install the drivers again.
Any combination of power and volume buttons just gives me a battery charging logo. Occasionally when holding up until the second black screen I will get a quick indication that the computer might see something, but it dissappears withing a handful of seconds showing it promptly removed.
I'm downloading the Android SDK in the hopes that when I get the normal at&t splash screen after the "jingle" that something might actually be running in the background and maybe I can adb reboot download it but I'm not holding my breath.
Anyone seen this that has managed to get out of it? I'm starting to think the "unbrickable captivate" can be bricked. Assuming it is bricked, short of taking it back, is there anyone on the internet that can jtag these and in some fashion bring back to life?
Cheers,
Tim

and download mode is easy.
1. start odin3 and have data cable plugged into the computer
2. insert proper files if needed
3. hold volume up and volume down for 2 sec (no power button needed) then insert usb cable, continue to hold volumes till either the download mode screen pops up or odin3 sees the phone(if you bork the phone bad enough you can corrupt the download mode image, i did it with the not to successfull manhatten project kernel) but despite the screen being black it very well may be in download mode.
4. start flash
5. if it doesn't work send it to me ill find a use for it
alternatively if the phone can go passed the splash screens and boots fully you can adb reboot download. just get the development kit and drivers on your pc.

just to be clear, you are holding volume up as well as volume down starting with the phone being powered down and continue to hold them after you plug in usb untill something shows on the screen?
if your phone is not seeing the volumes buttons you are one of the very unlucky few that had a problem at the most inopportune moment.
there is also a way where you hold all three buttons till the phone reboots twice, or something. let me try it and ill give more specifics.

Pull the battery, open odin, plug usb into computer, hold vol up and down, plug usb into phone still holding vol buttons, drop in battery still holding vol buttons, when dl screen pops up and yellow com port lights up in odin release volume buttons. Do not touch power button at any time
Swyped...and sorry I don't proofread

Have you tried rebooting into recovery mode instead of download mode? Stock recovery is adb-ready and you should be able to adb reboot download. Its a long shot if you're having problems using button combo to get to d/l mode, but it's probably still worth a shot at this point.
If you were able to use 3 button combos before all this happened, and did NOT have to install the 3 button combo fix, its strange you don't have access to it now... Could restoring a Rogers Cappy to AT&T stock be the problem?

Yes, that's exactly correct. I do this:
1. everything pulled (battery, USB, sim, sd)
2. Open Oden (1 click)
3. Install battery
4. hold down (and keep holding) volume up and volume down
5. insert USB cable
6. depress (i.e. don't hold) power button
Goes straight to battery charging indicator.
If I swap #6 with holding the power button down, it continually reboots while just barely showing the battery charging indicator. I've tried letting go between black screens on the 1st, 2nd, 3rd, 4th, and 5th black screen. Still no android dude with the shovel.

Try all the steps you stated but not the last one where you press the power button. Don't press the power button.

Trying to get into recovery mode gets me the at&t logo and the "jingle", but no recovery mode menu to reboot, etc.
This is what I'm worried about, restoring the Rogers stock over top of the Odin 1 click restore (which is an AT&T image) has bricked it and prevents download mode from invoking.

I know, I played with adb before I bricked it. ADB needs to "see" the phone, it no longer sees it (I have three computers, all three can't see it, but they can see my friends cappy with no problems first time, every time). Same process for his phone works every time to get into download mode, but not on mine.
And yes, have tried other USB ports on the same computer, both on the mainboard, and on the front ports.
Keep the ideas coming though please, I will try every one.

There's a trick to prompt download mode through a "jig" which you can hack together for about $2 in parts and a sacrificial microUSB cable...it works on the other SGSes, but I think it should work on the Captivate as well. Never tried it personally...

I work in a tech shop so have access to electronics, sacrificial cables, soldering irons, resistors, caps, etc.... could you point me in the right direction?

Oh, nevermind, found it in the i9000 forum. Will test first thing in the morning!
Cheers,

I bricked one today as well. Exactly what you are talking about here. The only thing is that i was still under the 30days so i swapped it out for a new one. As of right now ive been debating whether i want to do the voodoo fix (which i think is what bricked it to begin with)

Recovery Mode with three buttons

I have read over and over again that you hold down both volume buttons, and the power button, and it'll boot into recovery - but it's never worked for me. Last night, by accident, I let go of the 'up' volume button, only the 'down' was down along with the power button and low and behold - recovery mode. Is this proper procedure maybe only for certain phones? I was so frustrated, all that would happen with three buttons held down is the AT&T logo screen would flash on and off. I guess I'm just looking for affirmation here.

It's always been a fickle thing for me. I just use ADB for recovery.
Turn on USB Debugging, open cmd prompt in Windows, navigate to where you have android\tools, then adb reboot recovery
I prefer it because it is reliable. I know I can do hardware keys to recovery but I always seem to require 3 or 4 tries before I can pull it off right.

Thank you - I'm definitely going to have to get more familiar with ADB. I have it set up, but I've never used it. Reliability is what I want, I really don't like the panic attacks in the middle of a ROM install!

Let GO
I think you missed an important step of the process of getting into recovery.
After you see the AT&T screen the 2nd time, LET GO of the power button.
Some phones are quirky about which button to let go of, and according to some posts, european builds do it with just one volume button and the power button. (I think)
Anyway, glad you got there, but be sure to let go of the power button next time.
Out of curiosity, does download mode work?

I can get into download mode with Odin no problem, but not with just the buttons, unless I'm doing that wrong, too.
I did try letting go of the power button, but all that did was boot the phone.
These things are so tricky, and the panic swells when it doesn't work and you're trying to flash a ROM for only the second time in your life!

I know the feeling... when your heart starts racing in your chest..
Been there.

Hello everyone,
I cant use the 3 button combo at all to get to recovery mode. I've done the "Down Vol., Home, and Power" before and it worked. However, i am not able to get to it after i flashed Bionix-v 1.2, and 1.3. I pretty sure its not because of the ROM, but i just can't figure it out WHAT! I've tried the "Vol. UP, Down, Power" as well, but still not luck. Please help!
Thanks,
Yahase

Turn your phone off, and plug in the USB cable. That worked for me.

While your phone is switcher off, press and hold both the Up and Down buttons in the volume. And then plug in the USB.

[Q] Broken power button / how to boot without

Hello everyone
I own a Samsung ACE S5830. Recently the power button stopped working -- which was annoying, but I could live with. I just wouldn't lock the phone manually.
But now, finally, the thing I feared has happened: I let the battery run down.
My question is, of course: Is there any way to boot the phone other than the power button? Perhaps over USB?
Should the phone show up in adb devices's list, even if it is off? Because it doesn't, but I may be doing something wrong.
I am out of warranty -- so I'll have to get the phone serviced. Is it worth it, or should I just buy a new device?
Thanks a lot for your help.

Sorry to reply to myself.
Just wanted to let you know I suceeded in booting the thing. I don't really know how -- just hitting random keys while removing and re-inserting the battery, connected to usb.
I am starting to wonder if perhaps the power button does at least partially work -- any way I could test it? Obviously it doesn't perform normally, that is, not locking, booting, holding to get the shutdown menu, etc.

Hey!
If you can enter to DOWNLOAD mode(hold together 3 buttons[HOME+POWER+VOL DOWN]), then its probably working.
CHEERS!

Maybe this will be the solution:
1. Hold Home button
2. Connect to usb (or charger) still holding Home button
3. When in recovery menu, unplug usb
4. Select reboot system now
5. Succes?

Just created an account to say THANK YOU! YOU SAVED ME!

use adb reboot reboot commands
with adb you can start shut down download mode etc without touching phone

Well, my power button also kind of stopped working just recently, but if I press it really hard, it works Might be same for you.. However, it's still very annoying..

ZUK Z2 not booting anymore after restore

Hey,
so I was running cm13 (some version from november) and i wanted to go back to zui so i restored a backup that i created when i first got the phone. i booted into twrp, pressed on restore and selected my backup. after waiting for the backup to restore i saw that the process failed. then i pressed on the return to system or whatever button and now my phone wont boot anymore. when i hold power it just vibrates and the notification led flashes once. when i plug it in to charge the notification led doesnt light up. also when connecting it to my pc it is recognized (sound when you plug something in/out) but its not recognized as a phone or storage. what do i do?

Hi,
small question.
Did you do a full wipe?
Please delete system and data partition.
Because you come from cm13 to stock.

Are you able to enter fastboot? Press and hold volume down button and then hold the power button. Alternatively if your phone is off just unplug it and leave it for a few minutes, then whilst holding just the volume down button plug it into your PC and then check with "fastboot devices" in your terminal (I'm assuming that you do have adb and fastboot tools on your phone since you had a custom ROM).

@djsven I just went into twrp and tried to restore my back up not more not less. I cant delete the data and system partition as my device isnt turning on and my pc doesnt recognize the phone as a storage device.
 @Uivalf39 by holding volume down and power button i cant enter. all it did was vibrate + led flash. I think its on 0% power now because holding power now just makes the led flash once (no vibration anymore). can you tell me what exactly you mean by "check with "fastboot devices"".
thanks to everyone trying to help

You'll first need to install adb and fastboot tools, as well as drivers for the phone and google utilities. I assume you already have these since you must have unlocked your phone and flashed twrp to install CM13.
Sending the "fastboot devices" command through an adb/fastboot enabled terminal will show you if your phone is fastboot-enabled. Your phone is bricked, the only way to go back to the original software is to follow the guide (available both here and on zukfans), TWRP backup won't work with stock ROMs.
Don't worry though, you should be able to recover it, but it'll be a lot of trial and error.
Have a read through here and here and here, seems like a lot of good troubleshooting material for bricked devices.
Let us know how you get on.

My phone was recognized as QUSB_BULK in device manager. i installed qhsusb drivers and now its in ports and its called "qualcomm hs-usb diagnostics 900e (com10)". trying to find out what to do now.

Oh dear, from the stuff I found on Google, it sounds like you'll have to disconnect the battery to force the phone to shut down everything before carrying on.
Check out this thread on zukfans, specifically these comments: [1] [2]
This is the danger of having phones with non-removable batteries. Sounds like you might have to remove the back glass, shouldn't be TOO difficult, looks like it's just glued down without any clasps so you'll need a heat gun (hair dryer should do). Here is a guide on doing that.
If you do end up doing that, would you be willing to film it and upload it to YouTube afterwards? I can't find any video of such a feat and it would be useful for anyone else who needs to do that. Maybe even add some comments of whether there are any clasps, how long you had to heat it up, etc.
In the past I've been successful in unbricking my phones by draining them until the battery protection circuitry wouldn't allow for any more power to be drawn. This would roughly be equivalent to unplugging the battery so it might work for you depending what the phone is currently doing. If the screen comes on then you should be able to drain it, if only your notification light flashes then it's a fool's errand.
NB: The zukfans poster's step 1 was to fully charge your phone as you'll need full battery for the solution. What I described above will probably not work but there's always multiple solutions to every problem and if you're weary of removing the back you can try that, don't hold me on this, but I it shouldn't do any damage.

@Uivalf39
I managed to remove the battery connector. after putting it back in and now im trying to do the sequence i still dont understand because of bad phrasing (hold vol up then hold power then after 0.5s plug usb in? hold vol up hold power for 0.5s after plugging in? idk). all i now get is a slow flashing led when connecting it to anything via usb no matter what i press. i dont even know if its charging

After doing that, what do you have on device manager? Is it still as before with the 900e?
Alright, so from what I understand it goes something like this:
Unplug battery connector
Wait 10-15 seconds with the connector unplugged
Plug back battery connector
Press and HOLD volume up button
Whilst holding volume up press power button and hold it down
After 0.5s of holding power button plug in the usb (connected to the PC) - still keep holding the volume up and power button
Keep holding volume up and power button, and the ZUK logo should pop on the screen and phone should vibrate
Now release buttons and your phone should appear in device manager as port 9008
How did you find removing the glass back? How did you do it and how difficult would you say it was?

@Uivalf39 Im pretty sure im getting the timing right but all i get is a slowly flashing nofication led. no vibration and no logo. also my device doesnt get recognized at all on my pc i cant find it in device manager.
removing the back was pretty easy i just heated the 3 corners (the ones without a camera) on max for like 2 min each with a hair dryer. then i pushed in a plectrum and went around the edges with it.

@mdeoinko That's really strange, maybe we'll need to think a bit outside the box. What version of Windows are you using? Do you have the qualcomm/zuk/google drivers installed properly?
Here's one comment that might be useful.
Also, Francko from zukfans (main ROM guy so I guess he knows his stuff) did some trickery with the USB cable, not entirely sure what it is and how it works, but it looks like it does so you might want to look into this.
I'd say that you should maybe post to zukfans, you'll get more help there.
Godspeed my son!

@Uivalf39 damn i completely forgot about modifieng the cable brb hopefully i can fix it now

@mdeoinko
Hiya, any update? Hoping that your lack of posts means that you solved the issue and no longer need help. If so, could you post here what you did to solve it? Such that anyone else with this issue that comes across this thread might know what works and what doesn't.
Cheers!

i need help, cant signup into zukfans giving error as spam activity, cant go into 9008 mode, tried everything accept removing back of the fone. any guesses...
