Soft or Hard Brick Samsung Galaxy Note II: N7100

Soft or Hard Brick Samsung Galaxy Note II: N7100

 

I have my N7100 for almost 3 months now and yesterday my son accidentally spilled water on it. The whole unit did not get wet, just the side where the volume rocker is. And it switched off by itself. I removed the battery and let it dry for a few hours. I switched it on and yes it did turn on but one volume button ( - ) is not working and the back and menu keys are not working also and it does not recognize any touch on the screen but when I used the S-Pen it recognized it. It's a rooted, heavy customized and tweaked phone. I noticed that it went to "safe mode", it was indicated on the lower left side of the screen and all installed apps were gone. DPi value went into default. I tried to install some apps, it went successfully but I can not find it in the apps drawer. I went into recovery mode, hoping to remove it in safe mode (foolish me, did not even tried to read or search on xda for possible fix), re-flash a custom ROM but same thing. I also found that the two water damage indicators inside the phone turned pink. The components inside were dry when I opened it, but because I am eager to fix it I tried using a hair dryer to (of course) dry it a little bit without damaging anything. After a while I put everything all together, switched it on and it now recognized "touch". But issues with volume key ( - ) and menu & back buttons still remain and it is still in safe mode. I decided to restore it to factory default via recovery mode, I cleared everything, reformatted system, data, all menus with the word "reformat' I pressed them all. Restarted the phone and it just stays on the logo where it says "Samsung Galaxy Note II GT N7100". Tried to go back to recovery mode but with no avail. I tried to go to Download mode also, I was able to make it to the part where it says "press volume up to continue; press volume down to cancel" I then pressed volume up but nothing happens. I pressed the volume up and same thing. Tried to charge it while it is switched off, the battery icon charging appeared, it shows the circle animation but it does not animate and it doesn't animate also like it's charging itself. Plugged it into my laptop and it doesn't recognize it. I've been reading some XDA articles and I only came across one possible way to resurrect it...To get Download Mode without 3-button combo using homemade JIG.

Yes this will be my first post for my blog. The reason why I started a new blog because I can post any articles that I want even on the go using my Samsung Galaxy Note II, but since it's not working now, this posting while on the go will not happen for now. I just hope that I can resurrect this without spending any $$$ on it.

If I can repair this on my own, I will put it here because it might help others like me who is having the same issue.

 

 

 

 

 

 

 As of the moment I am trying to make my own Jig hoping to boot my Samsung Galaxy Note II to Download Mode

 

 

 

 

 

UPDATE: Too bad I was not able to resurrect the phone. Today is a very sad day for me. I will be sending my Note II to Samsung Service center for repair, I just hope it won't cost me too much.

How To Create Wireless Charger For Your Android Phone

How To Create Wireless Charger For Your Android Phone

 

You will need the following:

 

Palm Touchstone £5.24 (Amazon UK)
Palm Pre Touchstone case £3.49 (eBay)
Electrical Tape
Copper foil tape [thanks rj3005]
Solder Iron & Solder

Instructions: (Will use Samsung Galaxy Note II here)

 

Take the induction coil out of the Palm Pre case carefully.

!!! Its very important that you peel the silver sticker off carefully and not cause any sharp bends which could cause cracking. You need this silver sticker to stay intact for the whole operation to work!!!

The top pin is positive and bottom is negative as shown in the picture, this is also the same on the note the top pin being positive and bottom negative.
Place the coil in the center of the battery case then place the silver sticker over the coil as it was on the Palm Pre (this is very important that you place the silver sticker back over the coil as without it the induction doesn't seem to work.)
Check where the charging pins on the note meets with the case and marked it with a pen to indicate where the wires copper tape would have to be.
Using copper tape, stuck two tracks going from the charging circuit to the charging pins positions, make sure you leave enough copper track to fold the tape twice over itself to create a spring going against the charging pins.
Solder the track to the charging circuit by tinning the end of the copper track and soldering it to charging circuit contacts, then cut electrical tape to size and place it over the copper track. After place the original insulation cover over the coil with the magnets.
Place the battery cover over the Palm Touchstone dock and checked the voltage from the copper track with a meter (should be 5.6V any less means you have left the silver foil off or not placed it correctly) to check everything is working and the polarity is correct.
Place it back on the phone and there you go, you have now wireless charger.
NFC works and magnets do not affect the phone testing the S Pen and Compass seem to operate all good.
