[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:

[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] (SOLVED) Bricked/Bootloop weird

Hey guys,
I got an infuse from a friend. When she gave it to me it was all stock and functional minus the fact that it would bootloop. When you would turn it on it would show samsung, turn off, samsung, turn off... About 3 seconds per on time. It would do this whenever it had the battery in or was plugged in. At first I was able to get it into download and then flash stock OEM. This fixed the problem, then I got into recovery and flashed a custom rom. All of this worked fine. Here's the problem
I tried restoring to the stock that I got the phone to before the custom rom was installed. This took 25 seconds and I knew something must have been wrong but I rebooted anyway. When rebooting I was faced with my original issues up above. Unfortunately its rebooting too quickly to put it into download mod. By the time I press the volume buttons and insert the usb it already boots and then starts over. If I do it quickly enough it goes to charge and bootloops to charge. The problem is that the phone bootloops whenever the battery is in. I don't have to press power for it to start.
Pretty frustrated and really would like some help. Thanks
EDIT: I ****ING FIXED IT!!! I swear this isn't a joke... I was reading a forum that had this problem and they all were saying they got angry and threw it/hit their phone and it booted up. Sitting there I eventually started entertaining the idea. I did a quick survey of the library I am in and... smacked it on my fist. THEN THE ****ING THING BOOTED UP!! What the hell!! SO excited. If it happens again, most efficient way is to drop the device on the top off the phone on a carpeted floor from about 2 feet

Am I looking for a replacement or what? Thanks for the speedy reply

psal may be on to something however it sounds like you are not trying download mode correctly - if you had the battery pulled and the usb disconnected it could not be rebooting.
Edit: If the power button is sticking, most likely no need to replace- here is a video of how to replace the screen, not what you are doing but the point is it shows how to take the phone apart so that you can clean the power button. Hope this helps : http://www.youtube.com/watch?v=1WS5I0SpL6c

It reboots only when I put the battery in. So the moment I put the battery in to try and get it into recovery it starts booting immediately. It doesn't give me enough time to actually press volume up and down and then insert usb. If i do it fast enough it just boots to charging mode and boot loops to that instead of the samsung splash
Edit: I have already taken apart the phone. Not really sure what I should clean. It looks completely fine and acts similarly to the volume buttons. How would you recommend I clean it?

I am not so sure that this is a hardware issue. Why would the problem disappear when I flash the OEM but then return everytime I restore to the faulty stock. I already took apart and the power button seems pristine.

With this extra info, it is pointing more toward a sticking power button with a hardware issue still something to consider... have you tried pulling battery, install usb, hold both volume buttons (no power button) and while continuing to hold vol buttons insert the battery ?
Edit: If the issue is indeed in the faulty rom, delete it and use something different.

Not sure how I would delete the rom because I cannot boot the phone, boot to recovery, or boot to download. I did try having the usb in, holding volume and then putting in battery. It didn't work. Do you think a jig would work? Thanks

Yes, I think for such a small price it is worth a shot- best of luck !!
It would also be worth mentioning to be certain you have a good usb cable as well as a good usb port on the puter.

Use this to go to stock old version:

Then open kies mini connect your phone on kies update and upgrade to the newest GB version.
At this point u are on a stock if u want root try this:

I can't do this because in order to go to download mode the phone needs to be off. The moment I insert the battery it automatically starts bootlooping

Pony and psal are prolly right. Try fixing your power button.

[Q] Samsung Infuse 4G Rogers constantly restarting

Hello XDA community,
I installed a cm10.1 rom on my brothers Samsung Infuse 4G Rogers phone. It was working fine no problem and today, he shut off the data at work and now the phone constantly restarts. I tried different cables, different key combinations, pulled the battery for an hour and still nothing. The device does not connect long enough to the computer to even install drivers. Is there anything else that I can do? Or is the device pretty much a paper weight? I did research on XDA, Google and all the research that I could find led me to an unresolved thread or they sent the device back to samsung. Obviously it is out of Samsung warranty.
Am I missing something XDA? Please any and all help will be appreciated.
Thanks!

Does it boot or does it keep rebooting about every 3 seconds?
Sounds to me like a stucked power button..
This little test should say for sure:
Insert the battery and if it turns on automatically, it's the button.

Yeah, I guess I would have to take apart the phone and go from there?

That's practicaly it..
There's a thread around that shows some possible home-fixes before sending it for repair. It should pop up after a quick search
You could try cleaning the contacts or maybe soldering it back if you think you have the skills.

thanks for the help i figured the skyrocket would say sky rocket on it lol so i just jumped into the s2 i777 forum like a noob i feel so dumb but will the jtag thing for sure fix it

Almost nothings for sure but it's a pretty good chance they revive it. mobiletechvideos is who a lot of people have used.

yes i am for sure its hard bricked im so mad at my self i could rip my head off lol but i guess thats what i get for rushing into it im guessing everone would reccomend the mobiletechvideos fix for 50 instead of the 30 dollar ones on ebay or does it matter?

Spend the extra 20 bucks. lol It might matter or it might not. You don't wanna be the one that finds out it mattered though. lol

I would trust mobile techvideos over anyone on ebay. They have a stellar rep.

Hey there, Today my phone got stuck in a bootloop where the screen was black and there was an intermittent vibration. I couldn't get out of this bootloop at all. I tried getting into recovery mode, download mode, using Odin, holding down power for more than 20 seconds, removing the battery for 10 minutes, etc. Anyway, I figured, there has to be a solution without having to take apart my phone and trying to use JTAG, Geez! ANyway, I decided to try pressing the power and volume buttons in different combinations with and without the battery, and while being connected or disconnected to the PC. OK to make a long story short, here is the combination.
Plug USB into computer ( I used win7) without connecting it to your skyrocket.
Remove the battery from your phone.
Insert the Data cable into your phone without the battery.
Install battery and quickly press both the volume up/down button and the power button repeatedly (about 5-10 times) Basically press and release both sides at the same time over and over again until your skyrocket pops out of a bootloop. It took me only 5 presses.
I'm not saying this will work for everyone, but it worked for me. Due to the fact that this happened on a whim, I can't test it out to make sure the steps are just right. Whoever tries this, take note of the steps.
I hope this helps you guys out. Cheers.

what you have sir is a stuck power button, by repeadetly pressing the power button you momentarily "unstuck" the button, it can stay unstuck like that or it can become "sticky" once again, more info on that in the 1stop sticky

uhhhh, another person who is slightly misinformed. a boot loop doesn't equal JTAG. if your phone turns on AT ALL u should be able to recover it and get it working. JTAG is required for a brick, and like its name implies, a brick is just that. A phone that does absolutely nothing but sit there. No display, no sound, no vibrate, nuthin
