[Q] Phone won't stay in download mode?

I'm having some weird problems getting the phone into download mode. If I hold down voldown + power + trackball, the phone goes into download mode and is recognized, but then leaves download mode about 5 seconds later. The screen goes black and the charging screen turns on for a few seconds and then also goes black. If I just plug in the phone to charge, the charging screen turns on for a few seconds and then cycles with a black screen.
Is there something up with the charging circuitry? Is it possible to get the phone to stay in download mode?

Try doing the forced download mode method

Are you talking about the volume down + trackpad? Same thing happens, download mode screen flashes for ~5 seconds, phone turns off, starts flashing charging screen.
I also have a download mode jig, but that isn't working either.

Also, new development: the phone won't even turn on now when I hold down the power button. Bad battery?

No he means pull battery, connect usb, hold power, volume up, volume down, camera, and tackpad and insert battery. It should FORCE the phone into download mode.

That works, but I still get kicked out of DL mode after about 5 seconds. The issue was never getting into download mode--all button combinations work for that--but the problem is I get kicked out of it after a few seconds.

Hmmmm. I think its probably a bad battery.

Alright. I'll definitely check that out and get a new battery.

Got the battery today. Unfortunately, still the same problem! The Sidekick boot screen now displays in place of the battery charging screen, but I still get kicked out after 5 seconds.

Damn, well the only thing I can think is a problem with the board not receiving enough power. But I don't know, maybe someone else can help you better.

Another thread reminded me...
Fixed the problem! Seemed to be a ribbon cable or some sort of loose connection. I opened up the phone (all the way), removed the RF shield, unplugged all the ribbon/connector cables (minus the one for the camera) and removed the whole board from the phone case. Checked the connections, put everything back together snugly. It now works like a charm.

same problem
would you make a tutorial on how to do this ?

Yeah i had the same problem iv been trying to go into recovery mode and safe mode. I cant do it im having the same exact problem. I get kicked out every 5 seconds but Redct has a point. There may not be enough power going to the phone. I may attempt at taking the phone apart extremely carefully. If this works ill post then its a manufacture problem for not assembling the phone right or not finding out that people do lots of things with their phone and the phones is just a bunch of computer componets wraped around a piece of plastic. Better quality phones must be sturdy.

So I attempted to take apart the phone and put everything back together and successfully booted. I it booted into the Android OS but then for some reason crashed and entered the boot loop again god this is irritating

Same Problem
I am having the same problem. I took the phone apart, but I couldn't figure out how to get the circuit boards out to unplug the ribbon wires, can you tell me what to do? I had the same problems a few weeks back, but it was staying in download mode then, but now it won't stay in download mode for more than 5 seconds. I got a new phone because of it(LG Optimus). I would really like to get my Sidekick going again though!

Try using heimdal n enable flash bootloaders n hold the volume keys

I'm attempting this fix. Got arround taking out the board and just need some help with what to do with the RF. I can't simply take it out and put it back, my guess. Any help is appreaciated. Like what kind of tool would I need for that? Thanks!
The RF shield or the RF 5000? I'm confused.
BTW... If anyone needs help with how to dismantle the phone, follow this thread. It can be found in General section.

I know this forum is ancient, but I'm working on an E-Bay phone with this exact issue. I found the following thread the most useful and informative on the problem:

Samsung Infuse boots to logo..

I saw a Samsung Infuse 4g for sell as is. Only thing is it boots to Samsung logo then turns off. No water damage. Do you think can be fixed with a hard reset or some other solution?

Sounds like an easy fix. odin back to stock and your set. also if it already has CWM installed, super easy to instal custom rom with out the odin part

I just bought it for $160 in great condition with all accessories except for the booting issue. I should get it next week. Its a great price if I can get it to boot up. Any suggestions will help. Hopefully its an easy fix.. if not I'll throw it back up on eBay.

Its a really easy fix:
1) download odin-look in the super thread
2) put phone in download mode
3) run Odin
4) your phone will now turn on
This phone is 99% unbrickable...the only way its gonna brick is if you have actually hardware failure, if Samsung logo pops up then there a simple Odin back to stock will fix it
Sent from my SGH-I997 using XDA

Thanks for the suggestions. I'll post some more updates after I receive the phone and make the fixes.

Well got the phone used Odin back to stock...its up and running except camera. So I installed Zeus build 6 still camera not working.
Sent from my SAMSUNG-SGH-I997 using XDA

It is possible the camera was broken physically.
Are both cameras not working? Is there an error message that comes up when you open the camera app?
You might want to email the ebay seller and ask if they had trouble with the camera before it got bricked.

I found a solution. I turned my location off in settings then reapplied camera firmware. It works. The key was just to turn off my location. Weird huh. I can turn my location back on now too. Phone works good as new just flashed Zeus rom build 6 nice! But I miss my CM9 on my Captivate.

Similar problem
I'm having this same problem with my phone. It boots to the logo and then immediately turns off and does it again. I found ODIN-lite here, but that's where I'm stuck. I don't know how I can do step #2, put my phone in download mode, because it never turns on all the way. When I plug it in to my computer, it boots up to the charging screen and then promptly restarts. My phone is not rooted. Am I SOL?

I found the "stuck in a bootloop" thread. I've tried pulling the battery, putting it back in, holding power + both volumes when the Samsung screen comes on, and then releasing the power button. I've also tried to go into download mode by putting the battery in, plugging the USB in to my computer, and holding down both volume buttons. Neither of those do anything. If only the battery is in, it just boot loops to the Samsung screen, if the battery and USB are in, it bootloops to the battery charging screen. It never asks me what mode I want to go into when I'm plugged in to my computer. I'm pretty sure none of the buttons are broken, as I used them all the time before my phone randomly started boot looping.

Two things: to get into download mode, you pull the battery, hold down one of the volume keys (I forgot which one!), insert the usb cable, and put the battery back in. Or something like that. The crucial point is that you should be holding down ONE of the volume buttons.
The other thing is that you may have a stuck power key. Fairly easy fix. Find the thread in the General section.

Actually he is doing it the right way. One must press both vol buttons to enter download mode.
But effectively your phone seems to have a stucked power button.

[Q] Infuse Won't Power Up.

I recently downloaded SD Maid Pro, cleaned out all the double files and now the Infuse just blinks Samsung until it dies. Can't get it to go into download mode or anything else. It just blinks Samsung til it dies. I plug in the charger and it just shows the starburst loading emblem. Can't turn it on, once I unplug the charger, it'll show Samsung and then just blink. Pulled the battery, put it back in.. automatically Samsung comes up and just blinks. Tried everything. I think it's done. Any suggestions?
-Rob

Can you tell me step by step how you are trying to get into download mode...maybe you might be doing something wrong...also even if the screen goes blank after doing steps for download mode try and see if Odin/heimdal recognize it
Sent from my HTC PH39100 using XDA

Odin won't recognize it. I pulled the battery. Put it back in. Before I can plug in the usb cable it's flashing the Samsung screen.

Ok, try this
1) Pull battery
2) hold volume up + down
3) plug USB into phone/pc with Odin or heimdal running
4) place battery in
See if it boots into download mode that way
Sent from my HTC PH39100 using XDA

Nope, Just shows the starburst loading icon blinking like before.

Hmmm...well, if your not too sketched out and you pay for shipping, ill take a look at it and try to fix it...this is just an option and I understand if you don't wanna do that option ad I am a stranger and these phones ate expensive...
Can you check the power button...make sure its not stuck down...helped a guy not too long ago who had a similar problem only to find out his power button was stuck down

Yes, i've tried almost everything to get in download mode
download modes
nothing works it's like my power button is stuck, but it looks fine

M8, im dealing with the same situation with a couple motherboards. If im able to find a solution for that i will let you know. Ive done more than you have because i have even applied unbrickable mod to one of those two mobos with no luck. Pretty much same thing. The resurrector recognizes it but before it can resurrect the phone it will dissappear for good. So im starting to think it could be a damaged or corrupted file on the very lower levels of the infuse. But, at the same time, it maybe some hardware failure since i think unbrickable mod basically goes to the lowest level on the phone. Its a shame, but i have seen this many times on infuse phones. Never had to deal with that myself though....

Possible fix
My son brought me his phone last night with this same problem. I was not in the best mood to deal with it so made him, a teenager, go without a phone for a whole night....yeah dad of the year here. LOL. Anyway, I started working on it this morning and tried just about everyting I could think of until it thought of the Handyman's#! rule....If it doesnt work just bang on it. I took phone and with battery in it and cover on slapped it against my knee on the back cover in area where camera is. Dont try to break it just give it a good smack. Right after that it booted up and is just fine. LOL. I know it isnt the most scientific way to fix it...but it works for me and my son has his phone back. I hope this will help the rest of you out until we have a more defined solution.

[Q] Ultra Sensitive Power Button

i changed the title since that is not the issue any more. i re-melted the solder on the power button and it stoped the loops but now it just made it super ultra sensitive like its a touch screen button. any ideas?
so my phone just randomly shut off one night and it automatically turns on when i have my battery in and it just stays on the samsung logo for about 2-5 second and sometimes the touch key lights turn on but just turns back off and does the same. when i try to boot into download mode it doesnt go into it, it just show the image of the batter loading with the loading circle for about 5 second then shuts off. The phone its rooted but running stock. any help with be greatly appreciated!

If I searched for something like this I'd probably find info on the power button being stuck.

Already tried that solution, im slowly starting to think it is a hardware issues. there is no water damage at all.

Hey.
So I have the EXACT same problem...
Phone was on CM10 Jellybean (no OC). Randomly shut off and started to bootloop. Phone will start bootloop when battery is plugged in.
1) Put in battery while holding vol+/-
2) Put in battery while holding power vol+/-
3) Put in battery while holding vol+/- and USB plugged in (I believe this is the correct method of getting download mode)
4) Put in battery while holding vol+/- and USB Jig plugged in
5) Put in battery while USB jig plugged in.
I am all out of ideas. When there is a USB jig, the phone DOES get into download mode, only to immedialtly bootloop back into download mode.

Did you Odin or Heimdall back to stock (since you are in download) and see if it still loops?

Ehh i have other phones but i like to learn since i work for a electronic repair shop and this isnt the first time i ran into the bootloop issues but now i have some base on how to fix it... not not the ultra sensitive button part xD

Do you remember what the power button looked like? I think I am going to pay for this service. People have said they are reliable.

[Q] Im having issues with my phone right now.

Hey guys i have a samsung infuse 4g and one day it just turned off now it goes on and goes to the samsung logo then goes of and back to the samsung logo over and over again. i take the battery out and put it back in then it just does the same.

I really need help here. Its my moms phone and shes freaking out cause she cant afford a new phone so I need to get this fixed or atleast find out whats wrong with it. I let the battery die all the way down but still same issue.

This is a common problem. You need to get the phone into download mode and use either Odin or heimdall to revert the phone to stock. There are several links to several guides on the site, and the super everything thread has most of them. Search is your friend.
My Infuse is Stalking Beans

the phone wont even go into download mode because it shuts off too fast

Have either Heimdall or Odin on your PC ready to go with the correct drivers installed. Then take the battery out. Plug in the USB connection to the PC (preferrably a USB connection in the back of the PC). Hold Volume UP and Volume DOWN (but not the Power Button). Then insert the Battery, this will put you into download mode. Flash the "back to stock" of your choice.
If this doesn't work, you have a power button issue. Search for that fix then.

it's prolly the power button loop..look in the general thread and the q/a, M

Ended up smacking the phone around a little bit and fixed it right up xD good times.
