HELP!!! Cant Flash My captivate

I ran a lag fix on my phone and it booted and gave me a million force close boxes. i'd like to flash the stock firmware and start from scratch but everytime i run the one click odin .exe i get all threads completed fail. i wanted to make sure as well, the way i get to download mode is holding all 3 buttons, volume up/down and power till the att comes up a second time. when it does i let go of everything except volume down and it gets me to the android system recovery screen. I've now done the master clear which first tells me it fails but then says completed i then just pressed start and it tells me it fails. what am i doing wrong here. i am phoneless!!! help!!!!
Edit: to get into download mode turn the phone off, hold both volume buttons and plug the phone in while odin application is already running on your pc

You need to get into download mode. The button combination you're talking about gets you into recovery mode. These two are different things.
To get into download mode, do this:
1. Make sure your phone is not connected to your computer and the power is off. Pull the battery if you have to.
2. Start the odin one click program.
3. Press and hold the volume down button while connecting the phone to your computer. You should see the download mode screen on your phone (android with the shovel).
4. Make sure odin detected your phone. If so, press start.
Good luck!

Hey thanks for the reply, i've tried so many different combinations of holding buttons to get into a different mode and the phone just wont do it. i assumed the recovery mode was the one everyone was talking about. when i try what you suggested, taking out the battery putting it back in, leaving the phone powered off and holding the volume down and plugging the phone in all it does is bring up the green battery symbol and nothing else
EDIT:
Ok, it was that i had to hold both the volume buttons and then plug the phone in. that got me into download mode. awesome. plan to try the froyo rom then. thanks

Oops, thanks for the correction.
Good luck with the Froyo ROM. I think I'll wait until the Captivate kernel is ready for 2.2.

Stuck on ATT World Phone screen

Phone is stuck on att white world phone logo and is not going to download mode by holding the volume buttons and power, and or volume down and power.
When i hold the buttons and plug it in and all i see is a damn battery that goes on then off. Odin is open and does seem change.
All this just to get some bloatware and fix a gps.

Try the third option which is the only one works for me:
1. Take battery out and put back
2. Hold both Vol buttons. Don't touch the power button.
3. Plug in the USB cable to your PC. Don't touch the power button.
Your phone should boot into download mode right away. Remember, don't ever touch the power button.

WOW
wow dude perfect you saved me from freaking out! hah SOLVED thanks a million bad power button!

You're welcome. There is now even another hardware hack that can force the phone into download mode even if none of the buttons work. It is posted in i9000 forum.

Entering Download Mode but odin not working
I can get in to download mode but when I open odin3 there is nothing in the text boxes and when I press start it just says all threads completed 0/0 failed. And does the same thing for master clear.
When I turn the phone on with SIM in and hold the up/down + power it enters the clockwork stuff and I have tried the restore default option and recovery option. I was hoping download mode would help but didn't.
If anybody can help it would be much appreciated.
Thanks

Here is the procedure you need to follow:
1. Install the proper driver so that ODIN can see your phone when plugged in. Drivers are listed in the thread where you download ODIN.
2. Open ODIN with phone not attached. Select the firmware file (*.rar) you want to flash in PDA field.
3. Power off the phone and enter into download mode and connect the phone to PC.
4. Wait for the driver to install and your phone recognized. It will show up in one of the boxes in ODIN.
5. Once your phone is recognized, press Start button on ODIN to start the flash process.
6. Leave the PC and phone alone for a few minutes and pray (that your phone didn't get bricked in the process).

Ok I got it to recognize but I don't know what (*.rar) I am supposed to flash. Do i just put the cognition folder in it or what.
Thanks for the reply

I want to flash cognition but when i press pdf on odin3 it doesn't see it...any ideas?

Cog does not use Odin. Just get clockwork recovery and install it. Then boot into recovery and flash cog. Go to stickies in dev section, there are guides.

I try to select cognition.rar but says it needs a .tar file. What do I do to make it work?

Cog does not install with Odin unless dg added that. You need to unrar it. Download winrar and extract it, see what's inside.

This guide lays it out pretty well. http://forum.xda-developers.com/showthread.php?t=884364
Personally, here's what I use to do. Go to the Dev section and search for ClockworkMod Recovery. Search that thread for the update.zip. I'm sure it's in there. Put the update.zip on your internal storage, ie, when you plug phone into pc with USB the thing you mount and store file on, not an added SD card.
Boot into stock recovery. Choose reinstall packages, it reboots. Choose reinstall packages again, now your in Clockwork. Choose > install zip from sdcard > choose zip file > then navigate to Cognition (assuming you've put that on your internal storage also) and select it. It flashes, choose reboot. Bam! You're running Cognition.

[Q] HELP! Captivate won't go into download mode with volume +/- and USB!!!

I was trying to flash my captivate with adb reboot download and the battery fell out in download mode. I tried volume +/- to fix but no luck! Please help me! Stuck at Phone warning sign computer screen!

odin1click? volumeupdown + insert usb, open odin1click click go.
should fix it.

Doesn't go into download mode at all! Just shows the corrupted firmware every time I try it.

can you get a adb connection?

No, computer doesn't recognize it. If I had an ADB connection, I'd adb reboot download but when I try adb, it says no device found.

try plugging in usb with the battery out and then holding vol+- and inserting the battery while holding the volume buttons if not you need to make a jig.

I've had success with this method to get into Download Mode:
1. Remove battery, SIM and microSD from phone (if you have one)
2. Wait at least 10 seconds with the phone in this state
3. Plug your phone into your computer (this step has always been optional for me)
4. Hold Volume Up/Down, don't let go!
5. While holding both volume keys, insert the battery
If it worked, you should almost instantly be in Download Mode. I've omitted step 3 and still had success using those steps on my batch 1007 phone. In general, I get my phone into Download Mode first, and then plug it into the computer.

I'm probably just going to go to AT&T tomorrow and get them to exchange it if I can't get it to get into download mode tonight.

Didn't work, this used to work for me but now no luck. I don't know why it just stopped going into download mode.

Could you usb connect to PC on debug mode? Is this connecton visible from your PC?

That's a semi-bricked screen. No, normal method to go into download mode won't work in this state.
There are instructions to recover from this state into download mode. I have posted a few links in the past but don't have it right now. IIRC, you need to hold both vol buttons and Power button and wait until screen goes blank twice before release the power button so that your phone could go into download mode.
The other way is to rig a microUSB plug with a 301k resistor connected between pin5 and one of the data pin. This will put your phone instantly into download mode. There is a thread dedicated for this. Search.

I've been having the same issue and none of the methods mentioned on the forums have worked. I recently updated to a custom 2.2.1 rom (Paragon) and when I tried to flash back to stock with odin (afterwards), it gave me the finger (got stuck in the process). I tried to unplug and plug back in the usb, restart odin, pc, reinstall drivers (none of which helped). So my dumbarse decided to take the battery out to reboot the phone. Usually after doing so in the past, I've been able to manually get into download mode using the 3 button combo, but haven't been able to so far. I haven't tried making a jig yet, knowing me, I might seriously break something that way.
I was reading somewhere that 2.2.1 breaks the 3 button combo (along with 1 click root for that matter). Just wondering if there is anything else I can try or should I just make a jig? Should I take it in to AT&T and see if they can do something or should I call them? Just wanting some advice from the Gurus here.
edit: and "no, I can't do it through ADB or I would've already".

was going to suggest the same....thats only happened once (after install of gingerbread alpha) but that was the only thing that worked....the download screen literally jolted on the instant the battery connectors touched.

2.2.1 puts the 3-button setup to whatever the i9000 uses, which is different from the Captivate. Nobody's made a fix yet AFAIK.

for me i managed to get it into download mode, BUT, when i try running Odin it's stuck at "DO NOT TURN OFF TARGET!!"
any thoughts?

What build is your phone, located under battery. Something like 1010

Search for Sparkfun in the dev forum for Captivate. Easy to make jig (that's been mentioned before) that will get you out of the woods.

I am having issues getting into download mode myself. Samsung Captivate SGH-I897. I just got it less than two weeks ago. Played with some of the features. Did the root. Did the ROM manager. Everything I needed to do to have Serendipity 5.12 installed. Did it. worked great. Was missing some of the apps I enjoyed from the gate(Samsung EMail). So i read up that u could make a custom Serendipity in the kitchen.
Put the phone to JH6 from Odin. Also did the master clear. So now I am at 2.1 update 1 from Odin.
However, Now I cant get Clockwork Recovery at all ( when option is selected it goes to default recovery every single time ). I did try to re-install the correct flash for Clockwork, same results.
So, i thought maybe something didnt copy or flash or clear correctly and was going to do an Odin procedure again, cant get into download mode now. NOT AT ALL.
The phone will just re-boot into JH6. It operates normally, however I can shake JH6. No download mode. No Clockwork recovery.
I am noob, I am a quick hands on learner though. Not even sure if this will get the response desired.

excellent! and if the power button is stuck and let him yesterday when I left work without the battery and when you return in the morning and went back to get quickly rekindled, when you get home you have to hand screwdrivers do, many thank you! then comment as I was :good:

Two things can be wrong here. Power button or bad USB port. I replaced my power button that fixed only part of the problem. Can be imei problem. I'd put it into download mode flash back to stock. If problem persist you can rule out software n proceed to hardware. A way to test the power button is if you were able to boot into recovery.
One way to get it to boot up IF IF IF its not a power button problem
Slide out battery..... Slide battery back in ... right after you put the battery in plug in your USB charging cable(you have to do it pretty quick).... You should get a green recharging battery logo.... While this logo is up continuously press the power button...
Sometimes its just a bad/faulty or dirty USB port. Its a bit difficult to solder a new button thats that's why its best to make sure its the button. I'm talking from experience. you can clean the button.. I read some thread where people would just drop the phone purposely to get the button unstuck.
If not don't worry power button are pretty cheap on eBay as well as ports.

well ... Yesterday I opened the phone according to the video tutorial that I spend @amritn as seen in the image.
but when I do what you tell me to put the battery and place the USB cable quickly becomes thus passes this black screen, and press the power button nothing happens.
So if I saw this other tutorial yesterday and when I opened the phone yesterday I did the last step, I opened it and review only the shell of the phone does not have the button stuck and do not touch the equipment itself, not if I have to prove with doing what it says here in whole or proceed to restore the imei .... I say?
sorry for my bad English that comes thanks to google translator

reviewing found this video out there that is exactly what happens to the phone I have, just that I have that piece that put the end of the video that makes it ends in download mode
http://www.youtube.com/watch?v=AdSusfiSjqI
then ... that means the problem is if the power button?

If that exactly the same things happen in video, Then i'm afraid to say it's power button failure.
Or if u can go normally to download mode using volume up+ volume down and inserting usb cable when the phone is power of
go to my second process from heimdal one click and restoring efs. This may solve your problem if it's software related.

Samsung Galaxy A20e (SM-A202F/DS) bootloop | No more Download mode available

Hello,
I bought a Samsung Galaxy A20e, model name : SM-A202F/DS
First I unlocked the boot-loader,
then I flashed a TWRP custom recovery that I downloaded here :
https://drive.google.com/file/d/1Nbrmn7BgA3BxA1bqnLXYMuCY4KjpR0Vn/view
The custom recovery was working well. I tried to flash an another kernel in order to flash another system (various Android GSI I could find).
Apart from one kernel that seams to be flashed correctly from TWRP, no System would boot at any time.
So I decided to go back to the stock ROM of the phone temporarily.
To do so I found one on the internet, went to Download mode, and tried to flash it with Odin (v3.14.1).
The flash was unsuccessful. At that point I came with a blue screen (similar to download mode) telling me that I should use Samsung emergency recovery function in the Smart Switch PC software.
I installed this software (made all updates available) and went to the dedicated section. Unfortunately, no phone could be detected for recovery. But the PC could still detect the phone at that time.
So I decided to flash just the kernel (from stock archive) with Odin if I remember well. (unchecked other parts).
And since that, my phone is bootloop-ing when I plug it to the computer.
The screen first displays classic Samsung logo with model phone name and warning due to unlocked boot-loader.
And 2 seconds later, a little portion of the screen (top left) displays a message starting with:
“KERNEL REV. CHECK FAIL. DEVICE: 3, BI…” I can’t read the rest due to the front camera placement. I found results on the internet that it could be “kernel rev check fail-device:3 binary:x boot” for example. This message and only the text part is “backgrounded” with the same color as the Download mode blue color. And 5 seconds later the phone reboot for the same sequence.

Boot Img link [ https://img.vj.romanet.fr/samsung_a20e_sm-a202f-ds_bootlooping_1.jpg ]
I tried all combinations that could possibly bring me to the download mode or any recovery that could still be there.
Vol UP + Vol DOWN
Vol UP + Vol DOWN + PWR
Vol UP + PWR
Vol DOWN + PWR
Vol UP + Cable Plug
Vol DOWN + Calble Plug
Vol UP + Vol DOWN + Cable Plug
etc
The phone is still bootloop-ing if let plugged (USB to PC or USB to Charger), and get never detected by the computer. Neither on Windows 10 (previously detecting the phone) nor on Linux with "ADB devices" or "Fastboot devices" commands. I used 2 different cables including the one given with the phone.
I found a post on this forum, telling it could be due to damaged power button. I opened the phone, unlike the side panel buttons cable from the motherboard, same result.
If you have any ideas, they are welcome
Sorry for this huge post, hope my English is clear enough
Thank you very much and happy new year !

try heimdall, but dont use the gui, go on the internet find the instructions to flash all the nesscerray files, and done, i had a problem where my phone kept bootlooping back to download mode( bassicly i bricked it) and because i had linux i had to use heimdall to flash all files within the stock image

The screen first displays classic Samsung logo with model phone name and warning due to unlocked boot-loader.
And 2 seconds later, a little portion of the screen (top left) displays a message starting with:
“KERNEL REV. CHECK FAIL. DEVICE: 3, BI…” I can’t read the rest due to the front camera placement. I found results on the internet that it could be “kernel rev check fail-device:3 binary:x boot” for example. This message and only the text part is “backgrounded” with the same color as the Download mode blue color. And 5 seconds later the phone reboot for the same sequence.

I tried all combinations that could possibly bring me to the download mode or any recovery that could still be there.
Vol UP + Vol DOWN
Vol UP + Vol DOWN + PWR
Vol UP + PWR
Vol DOWN + PWR
Vol UP + Cable Plug
Vol DOWN + Calble Plug
Vol UP + Vol DOWN + Cable Plug
etc
The phone is still bootloop-ing if let plugged (USB to PC or USB to Charger), and get never detected by the computer. Neither on Windows 10 (previously detecting the phone) nor on Linux with "ADB devices" or "Fastboot devices" commands. I used 2 different cables including the one given with the phone.
I found a post on this forum, telling it could be due to damaged power button. I opened the phone, unlike the side panel buttons cable from the motherboard, same result.
If you have any ideas, they are welcome
Sorry for this huge post, hope my English is clear enough
Thank you very much and happy new year !

I found an app on windows that was able to put my android into download mode, after it did that I used the program to restart my device and quickly pushed the download mode buttons and flashed a stock rom

I also have this problem but I can't put the phone in download mode and I'm not sure what to do.

ReiBoot for android, when connecting your device it automatically put you in download mode, even though it won't look like it, using the program click exit download mode, it will put you in the boot option, quickly hold the power and the volume to enter the recovery options and choose download mode

There're obviously an Android and an iOS version available but they are paid applications.

It is paid but you don't need to pay for it, you can still use it without paying, It will still get you into download mode, that's free

Hey guys,
I just brought my phone (samsung SM-a202f) back from the dead it was stuck in emercency mode (asking to connect to smart switch) after I did something wrong flashing TWRP. I did it a million times but appearently I screwed up because my phone was stuck in the emercency mode bootloop and Odin did see the phone in emercency mode, but could not flash stock rom with or without bootloader.
I knew I had the right firmware (thanks to samfirm) and found the PIT file in the SCS .tar.md5 file. Just remove the .md5 of the name of the scs file and then unzip so you have the PIT file. What you do is feed that to odin under the pit tab and then use Odin like you normally would use it to flash a complete Rom on it.
Hope this helps someone. Happy 2022!
