So i've been having a lot of issues with my N5 lately, mostly small stuff like general slowness, poor battery life, not surprising on an almost 3 year old phone. I also lose cell service way too frequently (not an issue with my carryer, all my friends are on the same network and are fine). Camera won't focus anymore (though im pretty sure this was my fault, probably broke it while taking it apart). I'm pretty sure the battery connector on my motherboard is damaged. I've had many problems with the battery reading its temperature as -30 C (battery heath "cold"), i've replaced the battery 4 times now and i still get that problem every now and then. Pushing on the connector fixes it temporarily, so im pretty sure some pin is bent slightly out of place and i don't know how to fix that. It recently started having this issue where just moving or bumping the phone the wrong way would cause the phone to shut off. Probably an issue with the battery connector again. I tried fiddling with it but it didn't do much.
The other day i turned it on and the LCD was backlit, but black except for one single vertical white line. Rebooted and it looked normal. Few hours later i got really pissed off with it for shutting off in the middle of an important text and threw it at the wall (not the best idea i know). Screen was already cracked so i didn't really care. Ever since then the LCD has been a real pain in the ass. i can turn the phone on but there's nothing on the screen. Ii get haptic feedback when the Google logo would up, and the notification LED is flashing like i have a message. The backlight is on and pushing hard on the cable connecting the motherboard to the daughter board i can see it start to turn on, (Google logo, few seconds of boot animation) but then back to black (while still backlit).
I can post photos if it would help diagnose/fix this, my phone is my main camera and i don't want to bother anyone if i don't have to.
Anyone know any tricks that might squeeze another mouth out of this dying phone? Any response is appreciated, Thanks!
The issues could have been related to the power button or physical internal damage. My suggestion: replace the screen with a cheap 3rd party screen if the internal components are still working. This will give you more time with your existing phone and allow you to have a working backup.

Hi all,
I am at my wits end on this problem if anyone can offer any adivice it would be greatly appreciated. So let me give a recap of what has occured thus far. The water damage tag for some reason turn pink thus i am unable to get warranty exchange. I am pretty certain that the phone has never been expose to any water of anything of that sort, but i do live in houston, tx so might be humidity or what not that cause the tag to turn. Anyways.
1. This all started after i flashed RRE 5.2 RC3. Initially after a successful flash everything seem normal and fine. Then next morning i woke up to a frozen screen with many verticial lines running up and down the screen was almost unreadable. Initially i thought it was a bad flash or just random lock up. I did a hard reset and tried to enter the bootloader. Black screen, it does seem like the backlight is coming up but nothing on the screen. I can hear the phone power on and boot successfully into windows. Activesync connects i can browse the contents of the phone.
2. After flashing to stock att rom and stock htc roms same symptoms. So at this point i am thinking crap bad LCD screen. so I ordered both the digitizer and lcd screen for good measure. I replaced them hoping that a bad LCD was all. replaced both screens and i powered on the phone. same problem. black screen. The phone still powers on and boots into windows. Activesync still connects and i cna still reflash the phone.
3. I work extensively and do both desktop pc and notebook repair. I am not new to dealing with small electronic repairs. but at this juncture i am unable to identify the cause of hte malfunction. i am hoping maybe some of the gurus here might be able to shine some light on the subject.
Thanks in advance for any help.
I would have followed the same approach; your description makes it sound like it might be some kind of backlighting issue at first read. I'm inclined to think it might be a cold connection (bad connector) on the main board.
Silly question, what happens if you power up the phone with the keyboard exposed?
*EDIT* Not sure if you have been here yet: http://www.mikechannon.net/
Cheers,
i just tried to power up the phone with keyboard exposed. Powers up the same as with the keyboard hidden. Still boots up fine but black screen. I already have the service manuel dowloaded. i have checked around with several repair places both local and on the web. Seems like no one has any parts for the att fuze/touch pro gsm except for the lcd and digitizer and a speaker.
its quite possible that it is a main board but as the same time it might be something as simple as a ribbon cable. i have contacted htc about doing a possible repair and they want wayyyy too much for just a main board repair almost $400 USD.
Anyone have a bricked/ non working touch pro they would like to sell ? =P

Could be a bad ribbon cable ... and firmly pressing around the front/back of the unit shows no change?
pressing the phone front and back show no changes to display. in a very dark room I can see that there is light emitting from the display but its just the screen is not displaying anything visable. this occured both before and after i changed out the screens. I'll do another visual inspection of all the boards to see if there is any bad resistors burnt out circuits etc.. but i didn't notice anything mentionable during my first 2 inspections. Maybe 3rd time is the charm.
Thanks for all the feedback thus far Hilaireg it is quite appreciated. All this venting has at least made me feel 1000% better than after i replaced my lcd and still same problem at least i don't feel like a complete idiot!
Sorry I couldn't be of much help ... you've done all the steps a seasoned hardware person would do.
Do post back to let other folks know if you get it back up and running.
Cheers,
you have a pm fkoong.
I have possibly the same problem. Phone got wet, dried it out for 2 days (in a container of rice). Phone worked but had "water marks" on screen that disappeared after two days and everything was fine for about 2 weeks. Then one day (happened to be humid misting rain eve in Charleston) the screen is blank (hint of backlight only). A soft reset and it seems OK for about 1hr, then blank again. The hard resest screen displayed OK (readbale text etc), but didnt work. But as I write this, I retry to document it results correctly and the NATF ROM is reloading and the screen works! We will see how long!!
Well.. not that long, the end of the ROM load and it went blank again, seems like a video driver problem. The Press VoluP to boot does show some red artifact.
Trying hard reset again (No SIM no uSD)
The NATF v4.4 loads and gives me the Tap screen, Align Screen, stylus, loads customization, opera, tf3d, then loads a bunch of files under ...... and then the screen goes blank again, seem like what happened last time, so Ill try loading a fresh ROM copy... later
So, there I was, eating dinner while my phone read me a book.* And suddenly, it stopped. Because my phone crashed. And the amount of a boot cycle it can get through before crashing has been decreasing ever since. A complicating factor: when I still thought it was possibly a software issue, I booted into recovery, and attempted to re-flash the OS (currently it's on 10.2.1). It crashed partway through the process.
On the off chance this was a humidity issue (and not having a lot of time to mess with it) I opened up the phone, removed battery, sim, sd and the small screws in the main body of the phone, and left it in a dry well ventillated place. Now it will get as far as the initial "samsung" splash screen the first time I've reinserted the battery, and won't boot at all beside that. (It's possible that the power button was behaving weirdly, but the phone's behavior was generally so erratic that I can't say that with confidence.) Also, sniffing at the keyboard there is ever so faint a smell of burnt electronics... maybe. Maybe just platicizers. (I've noticed a bit of
This is the same phone that had screen issues (assumed to be related to a small amount of water** though subsequent evidence suggested a loose connector as an alternative hypothesis) around the beginning of February. It's been fine ever since, discounting the occasional weird usb connectivity issues that seem to be common with this phone.
I'm pretty happy to take the phone apart, but other than a general decase everything and look for loose connectors or other obvious trouble, I'm not even sure where to begin. (Also, I have about twelve hours to put in an order if I want Amazon to send by a new phone by tomorrow. Which is kind of silly, but this is swiftly and impressively dead. And otherwise it'd be no phone until Tuesday, which wouldn't kill me, but which would annoy me mightily.)
Any thought regarding common problem areas for this phone? I'm hoping to be able to leave the lab early today, which should give me some hours of working time. Well set up for tools, always happy to have things to take apart.
* Text to speech is awesome, once you get used to the robo-voice.
** Really, not a lot - none of the moisure stickers showed anything, and I don't think it got into the main body of the phone.
The de-casing was fun, and yet there isn't an obviously damaged component. It was pronounced dead at 6:20 yesterday evening.

Get a new battery for it....had this issue before and placing new battery in it fixed my bootlooping and not being able to flash or get past samsung screen...the samsung batteries have an overcharge feature which has been known for causing errors such as this...
Hi,
My Note Pro 12.2 P900 64gb is now stuck on the samsung screen of booting up and I am wondering if anyone can help me figure out what to do next.
I was experiencing the flickering issue for the last two weeks which got progressively worse and eventually caused random rebooting. One time last week it started booting slower and then it wiped out some widgets on my start screen and the apps in touchwiz but most everything else was OK. Then yesterday it would not boot up past the samsung screen. It charges up OK, and I can get to Odin where it asks if I want to load another operating system by holding power and vol up. But unless it is plugged in, just holding power off puts it in a boot loop.
The other part is if it is stuck and I hold power off it usually vibrates twice before boot looping.
I rooted the tablet when I got it, but still run stock touchwiz, I just needed some rooted apps namely LMT pie controls.
Can anyone please point me towards what to do next. Thank you very much for your help.
I guess wiping data and factory reset is your only solution right now
I shall warn you you could lose your data so I hope you already have a backup!
And also I've read that lollipop fixed flickering issue in p900 devices
I hope everything goes well for you
Good luck
hey there, you are not the only one, check this post. it seems is somethig related to battery issues

When power on, try pressing on the back, near the center with your hand. to see if it can boot normally,
Keep pressing while power on. if it works I will tell you what causing this problem.
https://www.youtube.com/watch?v=VeSG0hHpAG8
here you can look by the minute 2:30 where the connector is located, basically under the samsung logo. I'm not doing tests yet because i have a busy day ahead
Thank you all for the responses. Holding down the back while powering on does not help. I do have the flickering thing and that started leading up to this. Lay night I took it the battery and disconnected it for a half hour and that did not help. Looking at the connections with a 20x hand lens did not reveal any cracks.
I don't remember how to wipe the data off the device, I got it right when it came out rooted it with cf root and never got around to twrp. All I wanted was LMT and Xposed. I never even updated the OS.
If anyone can help walk me through this to get it running again I'll send you a green poetic skin used once or a white well used GumDrop hideaway case I tested for work. I just would like to get this running instead of needing to purchase a new one.
Thank you again. Sincerely.
Flickering screen is caused by cracked battery connector which cannot be seen under magnified glass. Re solder will fix it, trust me I did fix some of them

So resolder the 6 posts connecting the battery connector to the motherboard? Is there anything special I need to do that, just my soldering iron with a fine tip and solder? Anything special I need about the solder or do I need a wik or anything? The last time I did any soldering work was about 25 years ago.
Also will this fix the bootlooping and hanging on booting up at the Samsung word on the screen? If it is not going to fix that problem, maybe I should look at something else first.
Thank you very much again for your help.

First, pressing the battery connector help your tablet to boot is a confirmation of cracked battery connector solders. 90% flickering problem is from cracked battery connector. 10% is bad battery. You should fix the battery connector first as it's major defect seen in many Samsung tablets. Re solder is simple, apply flux, then heat these pins and add more solders as possible to secure these pins. Even new main board, this connector will crack just after 3 or 4 months depending how you use your tablet, especially with who using it on their laps. The main board sits on a flexible LCD and only 3 screws to hold it to the frame at 2 speakers. You don't need to remove the main board, just disconnect your battery and re solder the connector from the top.
Be careful as this connector is very close to other components. Trust me, this re work will fix this problem as I have seen in some cases, battery jumps up from 8% to 45% after the re work, other cases pressing the battery connector help the tablet to boot or stop flickering.
This person applied the fix and succeed.

I have the Note Pro 12.2 and I had this same screen flickering issue. It would start to flicker at first around the 38% mark. I did research online and found this thread and many others. I tried the software fixes like the enabling of Developer Mode and screen brightness and other tries, but to no avail. When I pressed on the back of the tablet, the screen flickering would stop but then shortly return. So I saw the fix of trying to raise the motherboard which worked for about 2 weeks, then the screen flickering did return. It would then start to flicker around the 58% battery level mark and when it got down to around 26%, the tablet would shut down. When I plugged it in, it would show battery level of 0%, then quickly jump back up to the 26% mark when it shut itself down. So then by this time, I saw more of this thread and now was shown the soldering of the battery connectors. I had soldering equipment, but it was too large for this repair as these 6 pins are very close together. So I went to the hobby shop and purchased new equipment for about $30 with a smaller pin to be able to do this. Now, I am not an electronics guy and my past experience was replacing two bad capacitors on my Plasma TV when it went bad. That was the extent of my experience to date. So I opened up the back of my tablet and soldered the 6 pins again and the screen flickering has not returned. I am on my 5th battery cycle from 100% all the way down to 2% and the screen flickering and shutting itself down has not returned. Some people have said an electronics guy will do this for you for around $30. Well, I spent the $30 and did it myself. I want to thank the people for posting the solutions here as the soldering worked for me.
And from this post, a confirmation that repair center will do the same thing to fix flickering , auto reboot, auto shut down.....etc...all problems caused by cracked battery connector ( Connector Header ):

Ok I'll try to resolder it this weekend and report back. I think that my pertinent problem is that I have both the battery issue AND another problem that the tablet won't boot up at all but I will try the battery fix first and see what happens. Then I will report back.
Thank you very much for your suggestions.
Your feedback is very important as I see many " Hit and Run " users, they get the solution they need but never post back. Your first priority is fixing the battery connector, then next is the battery if problem persists.
This is a hardware defect I have seen in many Samsung tablets: battery capacity fluctuation, quick discharge, auto reboot, auto shutdown.......all come from battery connector . Read the threat Flickering Screen you'll see others try all solutions but never work because they don't know this is a hardware problem coming from this tiny connector.
Hello all! Some time ago my nexus 5 started to have some issues with the microphone and a couple of days after it stopped working. I searched how people generally fix it because I have no warranty and I didn't want to spend much money giving someone to fix it or even get another phone. So what I did was I open the motherboard plastic protection and put a tape (a bit thick) right below the camera (above the battery) to make some pressure on the mic connection. I closed it, closed the phone, turned it on and the mic was working again. So far so good.
Then I noticed that out of nowhere the screen went black and if I pressed the power button it would give only black light. After some research again I noticed that it wasn't the LCD problem because if I rebooted the phone (power button + volume down) it would work perfectly, but after some time it'd go black again. Sometimes it even makes weird colors, grey orange and some lines (like broken screen) and then goes full black.
I already factory reseted the phone but the poblem still persists. I wonder if it has something to do with the battery (maybe should get a new one) or with some hardware connections. What makes me think that isn't a hardware problem is because it always works during some time when I reboot it. But ofc im not 100% sure because it looks like this happened a little while after the mic fix.
I saw someone talking about memory cache wipe could fix this. I did try this recently but I don't think this could be the problem and this is why: Some moments ago I tried to reboot it to make the screen work again but this time the reboot didn't work. It started to give those weird colors and lines. So I connected it to the charger, waited a bit, tried to reboot again and it worked. The screen is now temporarely on and working what makes me think even more that it could be battery's fault.
I hope I explained everything well if you have any doubt please do ask. I'm just trying to know exactly what the problem is so I don't waste time and money fixing actually non problematic parts.
Thank you.
PS: Before I got the phone like 2 months ago, it was used for almost a year by a family member.
Hi, my situation is; got a galaxy s7, the rear camera was bad, bought a new original one, stripped the phone down, fitted the camera, followed the tutorial (ifixit), put a new battery in at the same time, now rebuilt it all, (without the rear case on so can still easily take it apart again) and it wont turn on, wont go into safe mode, recovery mode, soft reset etc, tried every method, also via usb to my laptop, however it does charge, it comes up on the screen with the green battery icon and the LED light illuminates as if it is charging. Therefore, the screen is not damaged. And as far as i can see, all the connections are back joined onto the motherboard, it just wont boot up.
Also, if this makes any difference, I am running the Superman rom.
Any help would be massively appreciated as I have scowered so many websites searching for someone with a similar issue with a solution and I'm struggling, massively!
Are you sure you have connected the battery as required and no other circuit was touched?
Also, do you have the certainty this "new" battery works? I suggest you do the next 2 things:
1. Take this battery out and connect your old one. this way you can check if the new battery is faulty.
2. If doesn't work, even after inserting again the old battery, take your phone to a local repair center. (probably you messed something up).

I'd start by reversing everything you did until it powers on again, if it still doesn't power on with the old camera module & old battery in then start looking at other things, i'd probably start with the battery though as it is a power issue
The new battery charges and it comes up on my screen showing the green battery image charging so it is being recognised. Tried the old battery and its the same situation. I genuinely believe I didnt accidently short anything and im confident everythinf is where it needs to be. Ive just booked in to go to the samsung shop this weekend so hopefully they manage to find skmething althpugh probably end up costing a daft amount. Thanks for the replies so far

New camera module? Did you remove it to see if it is causing the problem?
I know there are different sensors, and if the wrong one is replaced the camera won't work, not heard about it stopping the phone booting but you never know
Just taken it to the local phone repair shop, lets hope they can find something with it. Keep you updated. Thanks so far.
