[Q] Stuck in AT&T Screen boot loop, can't get into either recovery or download mode

I went back to stock (or tried to) and after Odin was done the phone just stuck in the AT&T boot loop, download mode is not working (it was working before so I know I am doing the right combination/timing) doing endless combinations of Vol-/Vol+/Power doesn't seem to get me into recovery mode-

I put my girlfriend's captivate on Continuum over the weekend so I'm sure I'm pressing the right keys to get into download mode, but I get nothing but the battery.

I do have the Android SDK in my computer but I'm never able to get past that naggy screen, so I can't do a 'adb shell reboot recovery' is a JIG my only option?

To recap, can't get into download mode and pressing volume up / volume down and power buttonuntil the AT&T screen and then release the power button doesn't get me into recovery mode.

Need help!

I've been in the exact same situation.A jig is most probably the only option.

Many people have had this problem and find that a jig is the answer.

first try with just holding vol buttons and then inserting USB cable...hold vol buttons till its goes into download mode or the screen changes..if not then try following steps...

1. remove the usb cable, battery, sdcard, SIM.
2. wait 10 seconds, then insert the USB cable.
3. press and hold the 3 button combo while you insert the battery
4. continue to hold until phone's screen goes black twice and release power button.
5. timing is critical, it may not work the first time. Keep going until you see the COM port is connected properly.

still no Dl mode..then buy a jig or make one yourself

Right so I'm download mode now, but every time I go back to STOCK I'm re-stuck in the same loop, seems that I can't get out of it.

I got into download mode with a JIG, but still can't see my phone from my computer, so I can't run the adb shell to get it to boot in recovery mode

I'd appreciate any help you could give me!

Restart your computer, use a different usb cable, a different usb port. if that doesn't work, unistall the drivers and reinstall, restart your comp and try again.

For anoyone that might find this thread, Odin 1 Click didn't work for me, so I flash back into stock using Odin (not the 1 click version, another one), here are some links that proved to be very helpful (I ended up Flashing to Serependity 6.4):

I had the same problem just a few weeks ago.

The problem is once you start using 2.2 you can't use ODIN 2.1 anymore.

This is the one that worked for me I897UCJI6-OCD-REV02-Low-designgears(1)

this is actually a false statement.

i can still use odin 2.1 after flashing 2.2 roms and even stock 2.2 upgrades

Anyone thought about trying Heimdall if Odin doesn't work?

 

[langka]

Yes, i tried using heimdall and that didn't work. I'm wondering what leopic did to fix his, if you could list the steps instead of the links that would help a lot!

stuck in att screen and battery loop

so i have tried searching for threads that match the issue i am having and some of them do and some doent so i have decided to post this. i tried flashing back to stock from a custom rom i was using. i used Odin to do this. i didn't work so i tried it again, same result. it dosent boot just sits at the captivate splash screen. i tried using a different oden tool and after that it just loops through the ATT splash screen and if i have the usb cable plugged in, it just loops the battery screen. im not even sure if it charges. i have tried everything i can find to do to get the download mode to come up and nothing, just loops. i have not tried the jig on this phone yet b/c i haven't made it to radio shack yet to pick the resistors up. is that going to be my only option?

 

[TRusselo]

what rom WERE you on?was it cm7 or miui?

 

[TRusselo]

Connection Issues? < click here for information on download and recovery mode....

information you should have had BEFORE FLASHING your phone..

 

[asorendo]

i was on serinity 6.2.
i have tried all possible ways to get into d/l mode that i have found

 

[asorendo]

so from the link provided


FROM A POWERED-DOWN STATE - BATTERY REMOVED
- Insert battery, then press and hold Vol+ and Vol-, then insert your USB cable..
goes into battery loop
- Press and hold Vol+/Vol-, Insert Battery, Insert USB cable
goes into battery loop
- Press and hold Vol+/Vol-, Insert USB cable, Insert Battery
goes into battery loop
- Use a 301Kohm jig between USB pins 4-5 (can be manufactured jig or homemade chain of resistors)
have not tried yet

Sounds like a jig is in your future.

I had this problem before

Users - I am new on this forum and I know this thread is old however I had this problem and it resolved itself. Here is how.

Background: I tried to charge my ATT Captivate using a Nokia microUSB charger that was plugged into a 120v outlet. After a few minutes of charging, the phone would no longer boot past the ATT World Phone screen. Afterwards I tried everything under sun to get a computer recognize the phone so I could reflash the ROM. Nothing worked (different computer, different USB cables, reinstalled the Samsung drivers, etc....).

Resolution of Problem: As a last ditch effort, I tried charging my phone with the same Nokia microUSB cable that appeared to cause the problem in the first placed. This time the Nokia USB cable was plugged into my computer instead of the 120v outlet. My computer had the Samsung phone drivers installed. To my amazement the phone booted up after I unplugged it from the USB cable and all is well.

I am not sure what happened but my Captivate is back with no damage. Hope this helps some poor soul who is trying desperatley to get a computer to recognize a phone that for no apparent reason will not be recognized.
