I am trying to boot my samsung captivate into the boot loader. I've tried the physical key combos mentioned on XDA with no luck.
I tried using ./adb reboot bootloader but the phone does a regular reboot.
I am able to get a splash screen with that says "Download" and has a picture of the Android shoveling, by pressing both volumes and plugin in the power.
But if i do this, the device is not visible when I used ./adb devices
I am also able to boot into recovery using ./adb reboot recovery but I still cant see the device. I can also reboot into recovery with "One Click Root."
It says : Your phone is now in recovery mode. Select "Apply sdcard:update.zip" using the volume buttons and then press the power/home button.
But i don't see this as an option. my options are:
reboot system now
reinstall packages
delete all user data
delete cache data
formate internal sd-card
The question is how can i get this to reboot into the bootloader preferably from the terminal so that I can unlock it and install CWM.
Any advice would be much appreciated!
Running 2.6
Mac OS X
As far as i know, u can't reboot the Captivate into the bootloader.
But u could use Heimdall to flash a kernel that has cwm recovery built in.

[Q] HELP!!! Cant access recovery mode & WiFi isnt connecting at all [MIUI 1.11.25]
After I upgraded to the new MIUI rom, I noticed that the Gmail app and the Email app where crashing all the time so I thought it would be a good idea to to wipe the Dalvik cache, do a factory reset and reinstall the ROM...
I wanted to clear everything and start new... so I wiped the sdcard, sd-ext, data/cache, dalvik... then i flashed the Miui rom and made a new sd-ext3, made it 1Gb... the phone restarted normally, i installed the a2sd on the sd-ext3, everything was fine, I started re-downloading my programs. but then I restarted the phone and all the program I had installed were gone... and the a2sd+ partition was showing 0.00B of space while myy sdcard was showing that there was 1Gb missing... worse, the gapps (gmail, market etc) were gone... thought another factory reset would solve the issue, so I went into the settings/system/about phone/factory reset... it brought the gapps back but the a2sd was still showing 0.00B of space. not only that, but I couldnt connect to my wifi anymore (it keeps saying "obtaining ip adress")... also, ever since, I cant factory reset anymore... as soon as I do, the phone restart and is stuck in a bootloop... so I have to take out the battery and put it back to switch it on properly...
I tried to reboot it in recovery so that i could both reflash the MIUI ROM and re-install the sd-ext3 with less memory this time... but I couldnt get into the recovery mode no matter what. it was amon ra v2.2.1 recovery... I downloaded Rom Manager from the internet so I could switch recoveries, and I switched to clockworkmod, but still couldn't access the recovery. I thought Rom Manager wasnt not working properly so I tried flashing new recovery image through adb and fastboot, but it wouldnt even let me do it... looked for ways to bypass the recovery mode and flash the rom but it still wouldnt work... So now im stuck with the phone unable to go into recovery mode.
The phone otherwise still works, I still get and can make phone calls, but I cant connect to the internet unless using my credit, and even that for some reasons does not allow me to connect to google servers, meaning that I cannot use the Market...
How can I get My phone to work properly again?
I know you might have done this but I gotta ask the following:
- Did you pull out the battery, put it back in, and hold POWER + Trackball + Volume Down until you got to fastboot. Then select the recovery option?
- Can you please tell me what exactly it said when you tried to flash a new recovery to your phone via adb? What commands did you use to flash it in the first place.
Please provide more details so we can help you.
Is your phone unlocked? If so, the easiest way is to just reflash a recovery image using:
Code:
fastboot flash recovery "C:\location\to\recovery.img"
Then you can boot directly into the new recovery by changing the flash command to boot.
Code:
fastboot boot recovery "C:\location\to\recovery.img"
Then I would wipe the /system partition and reinstall MIUI.
Start a fastboot mode:
+ Download the fastboot http://dl.dropbox.com/u/8180983/N1/fastboot.zip
+ Extract the contents of fastboot.zip to some directory of your
preference
+ Download the su.zip http://dl.dropbox.com/u/8180983/N1/su.zip
+ Copy to the root of SD * Do not extract the contents, simply copy
to the root of SD *
+ Turn off your phone
+ Press and hold the trackball, press the power
+ The phone will connect in fastboot mode
+ Plug the USB cable
+ You will see a highlighted message "USB fastboot"
2 Unlock your bootloader:
<WARNING - This procedure below deletes all your
SETTINGS!>
+ At the command prompt / terminal, go to the directory where you
Drew fastboot.zip
+ If rWindows:
+ Go to Start> Run> cmd
+ Use the cd command to access the directory where you extracted the
fastboot.zip
+ Type-windows.exe fastboot devices
+ In the list will show your device
+ Type fastboot-windows.exe oem unlock
+ If it is Linux:
Run the + terminal of your choice
+ Use the force, become as root (su -)
+ Go to the directory where you extracted using fastboot.zip
cd
+ Enter. / Fastboot-linux devices
+ In the list will show your device
+ Enter. / Fastboot-linux oem unlock
+ If Mac, use the same steps as replacing the Linux
for fastboot. / fastboot-mac
+ Confirm unlocking
+ Now your phone will accept any customROM
3 Install any custom recovery:
- I used ClockworkMod, but there are others, such as Amon_Ra's.
http://mirror1.kanged.net/recoveries/recovery-clockwork-2.5.1.4-passi ...
+ If linux:
+ With the phone connected to usb fastboot mode and type:. /
linux-fastboot flash recovery <caminho/ para/ o/ arquivo/> / recovery-
clockwork-2.5.1.4-passion.img
+ If windows:
+ With the phone plugged into usb mode and type fastboot: fastboot-
windows.exe flash recovery <caminho/ para/ o/ arquivo/> / recovery-
clockwork-2.5.1.4-passion.img
+ If MAC:
+ With the phone connected to usb fastboot mode and type:. /
fastboot-mac flash recovery <caminho/ para/ o/ arquivo/> / recovery-
clockwork-2.5.1.4-passion.img
+ Okay, you installed a custom recovery and now has several
features such as nandroid backup / restore and etc..
- Accessing the custom recovery
Press + power and return to the bootloader menu, you will see an option
called RECOVERY, select it using the volume buttons and press
power to start the customrecovery
+ Will load a black screen with an exclamation point, press power
and the volume +
+ You are on the menu, scroll using the trackball or the keys
volume, to select, press the trackball

I could get to the fastboot and was selecting the recovery option, but then it was stuck in a bootloop. When I was trying to flash using the command prompt it was saying that there were errors. but Dont worry, I fixed it. Turns out the errors were due to the fact that the command couldnt find the location of the image...
ok i set up ADB
Rooted the phone with Superboot
oem unlocked
flashed recovery-ra-nexus-v2.2.1
here's the problem
Next step i want to do is to install a custom rom.
So I try to do the following
"1. Download the ROM you want from our Nexus One ROMs section.
2. Turn off the phone.
3. Turn it back on by holding down Volume Down and Power until the bootloader screen comes up. Let it finish searching then select Recovery by using the volume buttons and click power to select.
4. Once the recovery screen comes up, select Nandroid Backup (to save a backup just in case, optional)
5. Then select Mass Storage On and plug your phone into the computer.
6. Copy the ROM .zip file to your phone’s SD card then unplug the phone.
7. Click USB MS Toggle."
Problem is i don't see nandorid backup, nor do I know where USB MS Toggle is located.
Rom is on my SdCard.
can i just flash Clockwork? :/
go for 4EXT. its the best out there nw.

4ext is nice I use it now. did use amon_ra for 2 years no issues
don't like clockwork
if you go 4ext bu's are in clockwork backup folder
usb toggle should be on first ra screen under reboot now
nandroids or "backups" are under "backup/restore", however you should see nandroid folder on sdcard
if you just flashed a new recovery for first time did you remove this file to allow your recovery to stick--/system/etc/install-recovery.sh may be no issue for you at this point.
I'll try these out...
NP hit our thanks buttons if we helped
I managed to get into recovery and flash a rom, BUT....after I successfully install the rom and reboot. I just get a black screen that leads to nothing :/
Oh and the led buttons light up when i press the power button
Propably you just didnt wipe data. The entry is called something like format data/factory reset.

Did you follow this on installing recovery and removing stock recovery image as mentioned above, you can also remove it with root explorer if it is on phone
http://forum.xda-developers.com/wiki/Nexus_One/Recovery_Images#Installing_a_Recovery_Image
try to pull/reinstall battery and see if it boots
did you wipe all 3x with amon ra before flashing, should do system too--
http://dl.dropbox.com/u/28338566/Extreme-wipe.zip flashes from recovery
and I like sdformatter to format card then partition 1gb ext4 0swap
http://dl.dropbox.com/u/28338566/SDFormatter 2.0.mht
if battery pull don't work, pwr off and press trackball and pwr at same time and see if you can get into bootoader. there you can get into recovery, rewipe all 3x and reflash rom
did you check md5 with a a file mgr like es file explorer
what a2sd are you using, I prefer Dark Tremor beta4, flash it after rom and reboot, reboot again then with terminal emulator run the DT scripts as mentioned on Op of thread
worse case go back into adb/fastboot window and reflash recovery as per above link, wipe, and reflash rom
you can even wipe phone and fastboot rom thru command window by extracting the roms system and boot images and placing on sd card where you had ra recovery and fastbooting them--little more complicated and no need to try yet
just some ideas for now--
britemb 1332
Ok this is exactly what I have done from the start
Oem unlock
flashed recovery-ra-nexus-v1.7.0.1 (because the later ones don't work) through superboot
Went into recovery
I had previously formatted the sdcard with sd formatter as you suggested
converted ext2 to ext3
converted ext3 to ext4
-Did NOT use Dark Tremor, cause idk how to use it (don't understand instructions)-
wiped with Extreme wipe
flashed rom - Bugless Beast
reboot
and still black screen-led buttons light up and turn on and off as i press the power button.
hope that gives you a better idea of what i have done.
still no luck
can you get back to your stock rom
that recovery is too old
if so try ext4 from market or a pre 3.0 clockwork
am not sure why amon 2.2.1 won't fastboot
i did not use superboot so not familiar with it
i set up sdk/adb/fastboot--oem unlocked--fastbbooted amon ra--then flashed a rom with superboot in it
did you remove stock recovery
are you fastbooting the recovery or going thru a terminal on phone
i cannot go into phone and into market (as phone won't load)
I did NOT remove stocke recovery (link to file is broken)
and I am fastbooting the recovery
not sure what's wrong
you do have sdk installed? and when you type adb devices and fastboot devices you do see phone ID--?
and your images you fastboot are in your fastboot.exe folder ie "tools" for
it must be all correct or couldn't have fastbooted old recovery--just asking
do you have a backup (nandroid) on sdcard and maybe even backup sdcard at this point--i put all by bu's on pc as soon as i bu to phone
not sure what the lights mean
can you boot in to fastboot screen as i mentioned above and see hboot you have--could be an hboot or boot partition issue
not sure i want to instruct you on that--you would have to get correct hboot to fastboot
here is amon 2.2.1 i used
http://dl.dropbox.com/u/28338566/AmonRa 2.2.1.mht
fastboot flash recovery recovery-RA-passion-v2.2.1.img
Could try
1) Boot into fastboot and plug into your computer.
fastboot erase system
fastboot erase recovery
fastboot flash recovery recovery-RA-passion-v2.2.1.img
here is passimg link if you want to go back to stock and start over

I've done the Passimg method and nothing, still a black screen with the led buttons going on and off as you press the power button.
don't know--sorry
maybe google your problem
pull battery and leave out 15 minutes
try another battery
do you get vibrations when the screen goes off and any orange light
could be hardware
let's see what anyone else says

make very sure that you name the file PASSIMG.zip and not PASSIMG.zip.zip cos windows hadles the files such way.
after that reboot into bootloader (power+trackball) and then choose Bootloader by pressing power button. nw your phone should detect the passimg.zip and should be reverted back to stock.

My friend's s3 mini home button has malfunction and doesnt work. Well sometimes you forget simple things. He entered recovery mode from 4 way reboot menu and flashed a system that is not booting and always giving bootloop.
Now we really want to boot in download mode or recovery mode to boot the device and flash a working stock or custom rom.
The question is how to boot to recovery without home button if there is a way.

Open the phone and see if button can be fixed, or buy a cheap USB-jig to force it to download mode.
Good luck.
Use ADB:http://dottech.org/21534/how-to-install-adb-and-fastboot-on-your-windows-computer-for-use-with-your-android-phone/ :good:
1. Install ADB on your PC.
2. Download and install the Samsung USB drivers or, install KIES to get the drivers.
3. On the Phone, go to Settings, Developer Options and enable USB debugging.
4. Connect the Phone to your PC via USB cable.
5. Open a command prompt in your ADB folder. The text at the prompt should read C:\ADB. (You can just click on the Command_Prompt.bat to do this).
6. Verify ADB is working by typing "adb devices" (and hit ENTER) in the command window. You should see a device number listed for your Phone.
7. You are now ready to use ADB functions.
8. Below are the commands for your problem
- To boot into Download mode: adb reboot download
- To boot into recovery: adb reboot recovery
If this isn't work for you do what tys0n said

So I had unlocked my bootloader. rooted, and install TWRP, I tried installing cm11 which was in my sdcard, I factory reset, but when I when to look for the zip file it didn't come up in my ext_sdcard.... I did made a backup on twrp, but I don't have an os currently install, Idk how to boot into my recovery, I have the fastboot drivers install and when I put the phone in fastboot mode and run adb shell I get error: device not found.
What can I do?

To boot to recovery:
Power off device
Press and hold Power + Volume Down
As soon as the LG logo appears, quickly release Power and press and hold Power again until you see a screen titled "Factory data reset"
Use volume keys to scroll down to "Yes". Press Power to select
Do the same as before one more time
You will then boot in to recovery
As for TWRP:
Make sure you're using the latest version.
Up towards the top of the TWRP Install page there is a line with a gray background the starts with "Storage:". Press it and then select Internal storage or external sdcard. Now press "Ok" at the bottom of the screen. Now browse to the folder where your zip is.
Now for your fastboot ADB thing. The adb executable cannot communicate with a device in fastboot mode. That's what the fastboot executable is for. Where you used "adb devices" you should have used "fastboot devices". ADB is for when your device is booted in normal device mode or in recovery mode and the recovery supports USB debugging. Unfortunately you can't boot to recovery thru fastboot.

As in title - How to check if I have recovery partition installed?
I already flashed FTF with TA update by Andropax, but its doesnt work for me...
Any idea?
Thanks
Try do 'adb reboot recovery' or select reboot from recovery from power menu if you have any of those advanced power menu mods installed.

Won't work, the new recovery partition doesn't work with adb and so won't work with power menu mods either. Normally, POW+VOL DOWN and releasing POW on vibrate takes you to the recovery, if you've installed a recovery using 'fastboot flash recovery recovery.img' , but I find that inconsistent with Stock ROMs. If you're running an AOSP based ROM, that should work and it will directly take you to recovery.
so you mean the only way to check if i have the recovery partition is by actually flashing the recovery in fastboot?
If you are rooted you can download terminal emulator from play store. Run it, type in su and hit enter. grant super user access. Then type reboot recovery and hit enter again.
Your phone should now reboot into recovery if there is any. Otherwise the phone will just reboot to its system.
