[Q] Bootloop after disassembly - AT&T Samsung Galaxy Note I717

I was having some problems with my headphone jack and i opened my Galaxy Note to check it out. Took only those flat cables around it and used a Contact Cleaner. After that, it's stuck on bootloop.
I had a recovery mode installed and the touch wasn't working at all (TWRP)!
I tried to flash a stock rom, which removed the recovery mode, but kept the same problem.
What could i possibly try?

How far does it actually get before it loops back? Samsung logo? Boot animation? Home screen?
You might have a stuck power button.

Samsung logo.

I'm going to guess your power button is stuck.

Thanks for the answer.

The stuck power button is a very common defect in the original Galaxy note. It either gets literally stuck, or misaligned and is constantly pressed. I fixed mine by flicking the backside of the phone with my finger by the button. Some have fixed it by tapping the button rapidly. Others needed to take it apart and clean the physical button itself.

Couldn't be possible that the touchscreen is causing some sort of short circuit and the cellphone shuts itself as a prevention? I'm thinking that cause when i first managed to enter the Recovery Mode TWRP (before flashing a new rom), the touch wasn't working at all.
I'll try your alternative as well and will report tomorrow.

Bricked Help please!

My brother has a stock alltel 6800, brand new. He wanted to upgrade to dcd's ROM like I did but he thought he had to flash the 3.27 radio after the ROM so now he is stuck at the alltel screen. I have tried everything i could to fix it (which is still not that much because im just starting to flash myself) and nothing has worked.
Any help would be greatly appreciated
What dcd did you flash?
Hold down the power and camera button and hit the soft reset. Make sure you hold down the power and camera button after you soft reset till boot loader screen comes up. Load org rom.
bricked
DCD 2.3.2
and i did try holding down power+camera and hitting reset but it just restarts and goes to the alltel screen

i did but it just stays on the alltel screen
i know its suppose to bring you to the bootloader but when i tried it just did a soft reset
You have to HOLD them all down UNTIL screen pops up...if you let go to early it will just reset.
well its still not working
i just want to know if there is any way that you can get stuck on this screen with no way to fix it because for all i know one of the buttons might be broken

Pull the battery out, leave it out for 10 seconds, put it back in. Don't press the power button, but instead, hold power+camera and reset to enter the bootloader.
no good
tell me what i should do EXACTLY and what i should see while doing it then

hold power+camera and have your stylus pressing the button on the bottom of the phone...hold until rainbow screen
first of all, should it even be going through the reset routine (vibrates, htc screen, alltel)? because no matter what i do whenever i press (or hold) down the power button it resets.
So you are holding the power button and the camera button and having your stylus holding in the reset button on the bottom of the phone? HOLDING ALL OF THEM...lets say for 10secs?
still not working, just resets.
well one last question then,
i take out the battery, wait a little and put it back in, i hold down the buttons and it turns on, goes to the htc screen, then alltel screen.
is this how it is suppose to look or is it suppose to go straight to the bootloader because im now very certain that it must be a button malfunction
when holding in the buttons like that it should go to a tricolor screen...not reset...it will just reset if not held in long enough though
It is tricky but,,,,,
I have one that my camera button is sort of recessed a little and hard to make work, maybe his is also and may be even broken like he says as it is behaving like he is not holding the camera button. If it is new then I would take it back to them and say "it just did this" and play greeeeeen as grass dumb,,,,that is if you reeeeeeeally can not get it to the bootloader screen which would help.

Help: gTablet won't turn on any more

I've installed DRH JB 4.1 successfully 2 months ago. It has been running nicely since then. Today I decided to upgrade the ADW launcher EX. It all went fine.
I left the tablet on the table. A few minutes later, I came back to find it remains off. I tried to press power button for a few seconds, w/ or w/o holding + or - down. Nothing happens. Plug in the power, nothing.
I connect it to my PC (did that as a step to install DRH JB 4.1). But nothing happens either.
What can I do now? Is it completely dead?
Thanks
I've cracked open the back and press the reset the button. It boots up but won't respond to touch screen, soft button or hard buttons. I reset it a few times and about to give up. Then I put the back cover half-on (not snapped), it somehow worked. It responds to hard button, soft buttons and touch screen.
I felt lucky but want to try more. So I reboot it. Now, it only respond to the hard buttons, but not soft buttons or touch screen. Feeling I no longer need the reset the button, I snapped the back cover on. Now it goes dead again.
Has anyone seen this before? Any loose end?
Thanks
I just had this happen to my tablet today. Installed CWM 5.0.5 (for BL 1.2), installed the new Paranoid Android ROM played with it for a few minutes, went back to install market, which worked fine, logged in to start downloading apps. Played some angry birds, exited, admired the tab for a few seconds, turned off the screen, and then set it down. plugged in to charger. unlocked screen, made sure apps downloaded, turned off screen again, set down.
10 minutes later, picked it up, tried turning on the screen and all I got was black. will not respond to any button presses or anything I do. I would rather not crack open the case as I just purchased it, but will do so if that is the only thing aside from sending it in for repair.
Hope someone has some advice or help. Did search the forums for other ideas on what to do, but it seems like the only way to make it wake up is the hard reset. Someone please prove me wrong! :silly:

What you are having is a well known SOD that is caused by the Kernel we are using for right now. There are other options besides cracking the case and pressing the internal reset button. You can let the device drain its battery on its own. The best way I know of is to connect something that charges USB to the tablet so that the tablets power will die a lot quicker, MP3 player, Cell Phone or anything that can use a good charging up would be the quickest route. Then after plugging in almost everything and making sure that the battery is fully drained on the G tablet press and hold down the power button just to be safe and discharge what ever is left. Charge the Gtablet fully from red to green and then boot it back up and all will be good. Its a long process to take, but if you don't wish to open it up and drill the hole this is the alternative way of doing so.

Yup. That's most likely it. Loose ends. Check the cables going to the digitizer and the soft buttons.

Is there any diagram/photo showing where to check? Would really appreciate it.
What would be cause that the hard button does not work (power, volume)?
Thanks

For your problem, start reading from this post onwards. Pics are here.
I decided to open gTablet again. This time, things just come back to normal. I checked every wire and connector visible, but can't find anything loose. I am afraid to snap the back cover back so I am leaving it loose and put it back to the case. My plan is to drill a hole on the back cover later to get access to the reset button. But I doubt whether that will really help.
I am checking the pictures against mine. All looks normal. Checked every visible wire and connector. Nothing seems to be loose.

The symptoms point to a hardware problem. A visual inspection might not be enough.
Try pulling all the relevant cables out completely (at both ends), then plugging them back in again.
Then do a "Key Test" in CWM (under "advanced"). Post the key codes along with the keys pressed.
If all the keys don't show up, then get me a dmesg output:
Code:
C:\> [B]adb shell dmesg > dmesg.txt[/B]
You should also check that the cables don't have any breaks in them (flex the cable while doing the Key Test) or have their insulation stripped somewhere. This latter has caused some problems before.
I tried to tighten all the connectors.
All keys passed the test.
Keeping my fingers crossed now.

My S3 froze - now it won't boot? WTF?

I have an s3 that has been rooted running a custom rom perfectly for about 5 months.
Today I was using my phone and it locked up - totally froze..screen was frozen and everything was unresponsive. So I pulled the battery.
When I put the battery back in my phone displayed the Samsung logo and after that just displays a black screen.
I can put the phone in download mode, however it will only be on the download screen for about 3 seconds before the phone either turns off or the screen goes black.
The really weird thing is, when I put the battery into my phone it will instantly boot up (I don't have to hold download the power button). The power button is NOT stuck in the down position.
I know the battery is charged. So what in the hell happened? I don't know if my phone is bricked or not. I could re-flash it but I can't do anything in download mode because of it turning off.
Any help would be appreciated. Thanks.

When it tries to enter recovery mode I get the black screen as well
take out the battery. insert it after atleast 5 minutes. i've read somewhere that S3 is sensitive to the order of the keys we hold to enter download or recovery modes. so to enter download mode, 1st hold HOME button, then VOLUME DOWN button and then the POWER button. (not sure i did this all the time but no problem for me till now). good luck

Samsung Galaxy S3 Boot Loop Stuck

Hi guys,
One day out of the blue my S3 turns of then turns on again boot looping. It doesn't stop boot looping and the Samsung logo keeps flashing on them off. So i go and try to get into CWM Recovery and it doesn't work it keeps flashing so i try to get into download mode it goes to the option where it says 'Volume Up to continue' 'Volume Down To Restart' But in 5 seconds it restarts anyway and guess what it keeps flashing the Samsung logo again. I pug in my charger and the battery logo keeps flashing and doesn't stay still. WTF.... is going on?

Some people say to me its the power button is stuck because its not meant to turn on on its own but it does as soon as i put the battery in it does so what do you think?
Yes, power button is shorted out. Try giving it a wiggle.

Problem solved: It was the power button you must hit hard (not on the edge of a table) on the power button on a solid table, it has to be hard otherwise it wont work (don't be scared) but be careful hit it too hard on the edge of a table it will damage the screen or something else. If you are getting the same symptoms at I did i would try this as 95% time this is the problem, if you are still to scared that you might smash the screen or something open up the phone and clean the button out or keep wiggling the button although the hit on the table is the best solution/most effective. Hope this helped.

S3 Neo - loop while booting

Hello.
I get the Samsung Logo loop while I'm trying to turn on my smartphone. Phone was rooted several months ago. When i try to go to Download Mode it shows sign that I should press Volume Up or Volume Down but this screen disappears immediately and phone is trying to turn on again and shows Samsing Logo in loop. Is there anything I can do?
Sounds like the phone may have a stuck power button.
You could try to fix it by carefully removing the rear frame, cleaning around the power button with pure isopropyl alcohol, and then quickly pressing and releasing the power button using a bit more pressure than normal to see if that solves the problem.
By "stock" he means 'stuck'..
Yes, I meant to say "stuck", not "stock". My apologies.
Thanks for replies guys. I will do it in several days because i don't have time now. I will let know, thanks.
I cleaned it with alcohol and it helped. I have already ordered a new button. Thanks for help.
common problem, you can also carefully "bang" the power button to get it going again.
Yes, it works for now but I would like to have reserved button. Thanks for answers.
