How to unbrick the soft bricked Captivate

NOTE:
So far this has been the only sure fire method I've found to 100% get around any brick situation regardless of firmware, etc. This only works for the captivate, not any other galaxy s variant.
Situations: phone-!-Computer / no download mode
Black Screen / RST_STATUS 0x0
Procedure:
1. Remove the battery, external SD card and SIM card.
2. Wait 10 seconds.
3. Open odin3
4. Connect usb cable.
5. Hold volume up + volume down + Power.
6. Insert battery.
7. Release POWER BUTTON ONLY.
You should now be in immediate download mode.
Please forgive me if this is duplicate some where, but I tried every procedure I could find on google to no avail, then accidentally found this method just before I was going to box it back up and see if my buddy at AT&T would make me eat it or not.
My situation was: Launched Odin3 to flash H3 firmware, died twice in the middle, and on the third time locked up half ways just at the beginning of factoryfs.rfs -- Then the phone did nothing. Blackscreen is all. Interestingly enough, while in the state if you hold volume up + power, it will give a hw diagnostic screen. Beyond that I could get no where. Just a black screen, no acknowledgement when connected to PC, no charging indicator, nothing.
If this is a dupe Im sorry but this method I could not find and hope to make it readily available to people who may think their phones bricked.
Update 12/22/2010:
How to BRICK the phone / WARNING!!!
If for whatever reason you decide to use Odin to flash a stock GTI9000 ROM and manually add the kernels and modems using a "pure" 2.2.1 sammy rom. BEWARE.
Researching a lot, it seems the consensus is that the sbl in the 2.2.1 versions of the GTI9000 has *hard* download mode crippled.. Meaning if there is a software screw up YOU CANNOT USE A USB JIG OR ANY OTHER METHOD OF GETTING THE PHONE IN DOWNLOAD MODE!!! To fix it you'll need a new one or JTAG to replace the bootloader.
As far as I can tell, beyond getting completely rid of the AT&T logo, there is no need to flash boot/sbl to get the "purity" of the 2.2.1 sammy roms.
Extract all files from the tar EXCEPT boot/sbl and re-tar and flash just those to avoid overwriting the stock captivate boot loader.
Also, it does not appear the boot/sbl from the captivate 2.2 leak suffers this same problem.
For any one iffy on bricking their phones, stay away from roms that remove COMPLETELY the AT&T logo on boot. This generally means the boot loader has been messed with any you may be screwed if you soft brick the phone. Most CWM roms dont overwrite the boot/sbl, but some can and do. Watch yourself.. if it the AT&T logo goes away COMPLETELY, I recommend flashing JF6 with One click while the roms alive using adb reboot download and try another rom.

thanks!
worked...took a few tries but some trick with this captivate to get it into download mode.. i was totally bricked too, diag screen with PC/Phone icons and exclamation mark. for me 1.) plug usb, 2.) hold power and vol up/down and connect battery (it fell out) and i was in download mode

I guess a similar procedure was on the odin3 one click thread, but there is something different in your procedure, it's not my case but it would be nice if some people confirms this as this may be useful and if it really works it should be included in odin thread

What worked for me was: Pull the battery, sim and micro sd card. Open odin on the PC. Insert the battery. Hold vol up and down then with the buttons held connect the usb cable. Just remember to plug in the usb cable with the vol up and down held in and odin must be open on the computer.
I also ran into the vol up plus power red text screen. Interesting to note that one of the fields will change depending if the usb cable is connected or not.

mine is dead
mi samsung captivate was working great but, suddenly it go black and only the touch bottom have light, when i plug it in the a/c it show is charging. i'm mac user and a read that i ned to use odin3 but it not work on mac. how i can unbrick the phone???
is rooted with one click lag
the dbdata was modif to
thats all
HEEEEELLLLLPPPPPP

Odin will not open on the mac?
Cant you use a virtual machine and use Odin on a Mac that way?
Or else take the odin 3 single click for JF6 and use on a friends Windows Computer.

Please help - unable to flash back with Odin3
I have pretty much tried it all at this point and am trying to figure out what I'm doing wrong.
I followed the directions just in case get to the big yellow triangle with the droid shoveling and the screen stays at "downloading, do not turn off target..."
Of course I had Odin3 open already but its not seeing my phone, USB drives are installed am using Odin3 ver. 1.30.
Any help would be appreciated, TIA!

Best way to get download mode is use adb and type adb reboot download.
Or follow the volume up/down held with odin open on the computer, then you plug in the usb cable to the computer.

Just sharing the info! Makes you think twice about trying something else don't it?

does not seem to work because as soon as my battery touches the contacts it goes to the diag screen. do I have to release the power button in super human speed times there?
looked at all threads here, looked elsewhere -- there are some that are not fixable. Wanted to add that in case others come here and think that they might be the only ones that can't get it to work.
Ended up sending mine off to Samsung to reset today. :/

I love you! I called AT&T to send me documentation to sign and it was going to cost me 125 dollars to get it replaced even with warranty. And you fixed it !

i have tried just about every single method detailed in these forums, and nothing works.
Trying what OP suggested just sends me to the battery charging animation screen.
Anybody have any ideas ?

file analysis
I keep can get to the download screen and I hit start and it does the same thing everytime it just does File analysis i cant figure what i am doing wrong here somebody please help me

I think the issue was it had something to do with 64 bit windows 7 i just re did the stock rom one click solution and it worked fine

Thank you for sharing your experience.
I don't have a Captivate yet but am doing research on it and hopeful of getting one. I am confused about one thing.
Every where that I have read about how to enter Recovery mode or Download mode on the Captivate using the 3 button method, it says holding down both Volume UP + Volume Down (plus Power button) will enter Recovery mode. But you say it enters Download mode which is confusing to me. As I recall, to enter Download mode you must press the Vol Down only (plus Power button). Could it be because the phone won't go into Recovery mode, it goes into Download mode instead? Am I missing something?
Thank you!

Download mode is for updating the phone's firmware.
Remove battery, plug in the usb cable to the phone, open ODIN on the computer (need usb drivers installed before hand) on the phone hold volume up and down then plug the phone into the computer. Your phone will say DOWNLOADING. This method works even if you run into problems and the phone refuses to boot properly.
Recovery mode is for installing Update.zip. The method is tricky but involves holding volume up/down and power, the phone will show ATT then go black. It will repeat that but after the second time it goes black let go of power.
If that doesnt work, android debug tools ADB reboot recovery will work even better.
Or root the phone and use Clockwork Rom manager to boot into recovery, just press the menu item.

Thank you askpcguy! I understand the difference between Download and Recovery modes.
So the procedural difference here is having the battery in + Power button, versus battery not in (use USB cable instead) and no Power button. Can the phone get power from the PC via the USB cable? This seems to differ from what the original poster said about download mode. Perhaps OP could edit his original post for clarification? Or am I still missing something? Thanks to all

The phone does get power from the USB cable.
The difference is one procedure uses the USB cable (download mode) and the other does not (Recovery mode).
The volume up+down method does not use the power button, the phone is powered on into download mode once you plug in the USB cable.
We say pull the battery to get the phone powered off. If a firmware flash stalled or doesn't complete, pull the battery and try again!

I now understand the precedural difference.
Thank you askpcguy!

Sony Xperia Z3 HARD BRICKED

Hi. My device is hardbricked. I see no lights while charging. Flashtool doesn't see my device.how can i fix this?
Edit:Easily fixed it.I plugged my device into the computer.I entered platform-tools and flashed boot.img.I saw "waiting for device" And i pressed volume up and power buttons. Suddenly boot flashed and i recovered my phone

You are very unlikely to have hard bricked it unless you have unlocked the boot and flashed something wrong.
If you did this please help us help you by telling us what you did just before this happened.
Also, just leave the phone on charge (Wall charger) for 24 hours and then see what happens.
In the mean time read this

solution for no LEDs no response no fastboot devices.
Take two rubberbands one to hold down the power button and one to hold down the volume up button on Xperia Z3 dual. I spent a lot of time figuring this out. Alter a few minutes the phone just booted up from the dead. It worked for me 3 times. Now if someone can tell me how to fix the fastboot remote command not allowed error I'll be happy.

Hello
I had the same problem with REMOTE COMMAND NOT ALLOWED till i managed to solve it.
1st thing you need to clean that ANDROID folder you made on C: drive.Install all from the begining including flashtool.Boot windows to install unsigned drivers.In the flash tool folder youll find the driver downloader,just enable usb debugging and choose Mass Storage not MTP .; You have 4 options usb debug on/off and usb connectivity MTP or Mas Storage ;with every version selected connect and disconnect from pc with flashtool running.
When you use Fastboot start the flashtool and close it if it cant kill ADB (that assuming you succeeded in installing drivers).
Good Luck

Try a different driver package from another download source and use another usb on your pc.
Maybe it works. If your device can enter flash mode it definitely can be recovered.

The green led indicates flash mode so the problem is probably on your PC not detecting it properly. Does it show up in the system manager of windows if you plug it in at all? (Like a new device/android with a yellow triangle)
You could also try to fastboot a recovery and flashing a ROM from there. Not sure if it works but that's what I would try.

i m not even able to fastboot a recovery ...tried twrp and cwm both of them...

Me too

in my phone after charging 24h, only the red LED blinks, this is not normal any suggestions?
--------------edit
ok another week and still nothing
maybe I'll describe the problem:
I wanted to upload clean soft 5.1.1 and flash it
after the phone turned off it's start in recovery i used zip with SU and the phone turned off with no respond i try too reset (vol- + vol+ + power) but no reaction
there were no three vib
so I found that you have to reset the button under the sd flip
after this treatment you already know the charging of 3 days and only the red LED blinks
So any suggestions??

I‘m having the same problem, I can’t open my Xperia Z3. I tried with holding on/off button, holding volume up and on/off button, holding volume down and on/off button. When I connect it to PC, nothings happen. No vibrates, no led on, no screen on. What should I do?

Like you I have a Xperia Z3 mines the 6633 variant.. Signs were showing it to be hard bricked, for example:
No led charge indication!
No power led!
No fastboot leds!
No USB detection sound when plugging into windows.
Literally a Z3 that was essentially a glass brick I bought off ebay for £6.50 GBP for spares/repair.
Since I had a bricked device, I had nothing to loose.
I applied heat to the rear glass with a hair drier & removed the panel, I removed the battery ribbon cable & plugged in via USB only to find the phone would show LEDs so put it on charge.
The Z3 now goes into flash mode, so then re-flashed a stock ROM from flashtool. I did a apps log & user data wipe, cust reset & fota reset.
To date I have no idea why the phone would not take a charge before or even detect via USB, though Id say give this method a go, you may be surprised!!
Good luck

[Q] Soft-Bricked (I think) not being recognized by PC or Flashtool

Hi everyone. My first post after about 48 hours of reading and trying to fix this problem on my own. I think I've tried about everything. I'm new at this stuff so bear with me.
I have a Xperia z3. Rooted. I had an issue with a locked safe mode and I flashed the phone with some modem file which ended up bricking my phone. I've followed just about every thread related to getting a phone out of soft/hard bricked state. What it comes down to however, is the fact that my phone does not communicate with my computer in any shape or form. It does not show up in device manager in any way. I do think it charges....but not even sure of that because I have a constant red light.
Basically, as you'll see in the attached screenshot, I'm at this stage. I've charged my phone for over 24hours. The red LED is lit. When prompted to plug in my phone, I do so with the volume button pressed down....but nothing happens. I've done the elastic trick and had it attached over night. I've done a hard reset, discharged the battery, and charged to red led and tried again....but nothing. Phone is not recognized whatsoever. I've tried different cords, different computers, different programs to no avail. I'm at a loss as to what to do.
Ps. I've followed instructions on how to install Flashtool properly, with Flash Mode/Fastboot and Xperia z3 drivers.
What to do next? Any suggestions

nothing specific, just ideas out of my mind:
- try a different USB cable
- try a different USB port
- try to shut down the phone (I think, this is some combination of the power button + volume down)
- did you let the phone boot into flashmode (when off, hold volume down, then connect USB cable)?
maybe, this helps: http://forum.xda-developers.com/z3/help/xperia-z3-d6603-flashmode-problems-t2986336

Thanks for the suggestions.
- I've tried 4 different USB cables, including the on that came with the phone
- I've tried about 10 different USB ports on 2 different computers and a laptop
- I've hard reset the phone a number of times (Power button + volume up, 3 vibrations)
- Every time I've tried flashing the phone I've held the volume down button to make sure it's set in flash mode
No luck thus far...

So if you enter flash mode, does the LED light up (I think it is blue)?
And you did install the device drivers?
Did you try the official Sony flash tool or this other one?
(sorry for not adding links)
What you could also try is to download a Linux live image, boot this (from a CD or USB drive), which will not change your current pc setup, and try commands like lsusb (list attached USB devices) or dmesg (show kernel messages) to see whether your device which is working somehow is recognized at all.

I've already tried your above suggestions a number of times. Booting a live image of Linux on the other hand, is something I've never tried. I'll definitely look into it and see if it helps. Thanks Abprie for the suggestion.

booting a live image is really very easy. burn the image to a cd (or dvd). boot from this. after loading, open a console and type "lsusb". connect the device, and retype "lsusb". if it is properly connected it should at least show that there is now another usb device present. you may do the same procedure for "dmesg".
sorry, no more ideas.... :/

Sony Z3 D6633 is dead , wiped system accidentally ,Led not Blinking, screen blackout

Hello There
I was trying to hard reset my Sony Z3 D6633 and I firstly wiped the Rom then after that I tried to install Stock Rom using "Sony Mobile Flasher by Androxyde" , unfortunately the power went of while it was flashing and now the phone doesn't even boot or show any thing on the screen , and the led doesn't even blink , I tried the following :
-pressing the volume down then connecting it to the flasher (No Response)
-pressing the yellow reset button in sim tray 10 times then connecting the charger (No Response)
-holding volume up and power together (No response)
I'm currently putting it in charger but it doesn't give any response , I think I deleted an important part in the system , is there's any software that could help me ,if someone could guide me I would be very grateful for him/her

Usually a normal flash with a flash tool shouldn't brick your device in a way that it can't enter stock recovery or download/flash mode.
Did you check the device manager when connecting with volume up/down?
You can try EMMA by Sony to flash full stock, but you need to follow a tutorial to set it up (there's a specific file you need to put in the install directory of the program to skip the devs login).

When connecting the charger does the red LED light up?

Resolved
Sorry for the long absence, after three days of posting this i was about to give up until I plugged my phone into the charger and the led turned on which was a good sign that now I know that the device is still working, after charging it for a couple of hours I connected it to the PC and used "Sony PC Companion" and followed it's steps, and the device was restored to it's original firmware.:laugh::laugh::laugh:

Please help me

Hi
I've made a bad mistake which I'm hoping people can help me with. I tried updating my phone wit MIUI 8 as I had an issue with my battery. My updater app on my phone was not working so I downloaded zip file and tried doing it manually from the app. Then my phone just turned off and I'm unable to turn on or charge. None of the button combinations work and when I plug in to my laptop through usb port I get a message saying it doesn't recognise device. I've tried using unlock function on website but get error messages in chinese around ip address to malfunctioned phone number so no luck there.
Appreciate any help as I had a lot of information, apps and data that i would hate to lose. I lost my wife 3 months ago and I have some precious memories on that phone. I know I should have done a backup beforehand and that was stupid of me.
Is there anyway i get can my back in without losing data. if not then anyway at all to get my phone working.
Thanks, from a very down MI4C user

Try holding one of the power buttons(don't remember which one) and plug in the cable so the phone boots into fastboot mode. If you manage to get into fastboot boot TWRP and copy your files straight from it as it has mtp support. If your PC sees your phone as an unrecognizable device there's a big chance you can recover your data. Last hope would be to use a modified usb cable for edl flashing although this way you'll most likely lose your data.

Thanks, first suggestion doesn't work unfortunately. I have now been given permission to unlock bootloader but problem is the device is not recgonised due to usb issue.
So I cant turn on, won't charge etc and none of button combinations work. Has anyone encountered the issue with usb before. Unsure of 'modified usb cable for edl flashing'. All very frustrating.
thanks for any help

Anyone else have any ideas. Desperate here without my phone and important data

Have tried everything at this stage...utter despair. My phone just won't turn on or charge or enter fastboot mode etc
Anyone please help

The modified USB cable that I spoke of is used to force boot the phone into emergency download mode. It's baisicly a last hope flashing method that should work regardless of how broken the phone is. The only downside is that using this mode you only can flash via miflash and this will wipe your data. As for the cable you can either make one (look for deep flash USB cable schematic, it involves swapping 2 wires) or just buy one. Once you get into edl just follow the unofficial bootloader unlock guide to flash the 6.1.7 rom as it is flashed in the emergency mode.
Edit: whenever you plug your phone into your PC does the screen or led diode light up at all? You can also try holding vol- and power button and plug the phone into a charger (not PC) to see if it will respond at all. Charger gives more current so maybe it will force the phone to boot.

Thanks Adi. I don't think I will be able to make one. I've seen some threads elsewhere about getting into EDL mode, do you always require modified cable to do so?
Nohting happens when I plug it into PC, no lights etc. Tried charging using normal power supply but nothing happens either. Have even tried connecting to powerbank overnight but no power is taken from it.

So there is no "unrecognized device" popping up in windows anymore?
If so, let the phone lie for 1 more day (without connecting any power sources to it). Afterwards charge it (with a normal charger and a cable that works for another phone) for about 2 days (or until you see the notification led charging). if nothing happens you can try a different charger or an usb port for another 2 days.
If your computer recognizes the device ("unrecognized device" or just any reaction by connecting the phone) try to reinstall all the drivers (xiaomis/qualcoms, as well as adb, fastboot) and see if there is something happening.
Report back if it helped.
Edit: Did you try different cables? had similar problems with op2 (not recognizing) with xiaomi cable...
Edit2: to make sure the device is completely dead, use a linux distro (e.g. Ubuntu, ensures that there are no driver problems, you can install it on a usb drive) and a cable which surely works (try it on at least 2 other phones, if data transfer works its ok) then first install fastboot (ctrl+t to open a terminal) by copy/pasting "sudo apt-get install android-tools-adb android-tools-fastboot". Afterwards hold vol- and power button for at least 12secs and plug mi4c in (release the buttons after plugging it in). Now you can run "sudo fastboot devices" and see if there is sth listed (should even recognize it in edl).

You don't need to use the modified cable as you can enter edl from fastboot, but the cable method is used to force the phone into it if you can't enter it the normal way. As for rescuing it, try the method @wertus33333 suggested.

So there is no "unrecognized device" popping up in windows anymore?
If so, let the phone lie for 1 more day (without connecting any power sources to it). Afterwards charge it (with a normal charger and a cable that works for another phone) for about 2 days (or until you see the notification led charging). if nothing happens you can try a different charger or an usb port for another 2 days.
If your computer recognizes the device ("unrecognized device" or just any reaction by connecting the phone) try to reinstall all the drivers (xiaomis/qualcoms, as well as adb, fastboot) and see if there is something happening.
Report back if it helped.
Edit: Did you try different cables? had similar problems with op2 (not recognizing) with xiaomi cable...
Edit2: to make sure the device is completely dead, use a linux distro (e.g. Ubuntu, ensures that there are no driver problems, you can install it on a usb drive) and a cable which surely works (try it on at least 2 other phones, if data transfer works its ok) then first install fastboot (ctrl+t to open a terminal) by copy/pasting "sudo apt-get install android-tools-adb android-tools-fastboot". Afterwards hold vol- and power button for at least 12secs and plug mi4c in (release the buttons after plugging it in). Now you can run "sudo fastboot devices" and see if there is sth listed (should even recognize it in edl).

Did it work?? Any information would be appreciated, so the next one with this problem doesn't have to open a new thread.... @colb16

Apologies for not updating, I got an answer on MIUI official forum from a very helpful member called Codex. Below are steps he asked me to follow and although it took a few attempts my phone came back to life after following below and then pressing power and volume down for numerous minutes.
