Hello I'm having some serious trouble with my android device. Whenever I turn it on it will just show a white screen. I can put the phone to sleep and when I press the power button again, the screen is still white. I can hear my text ringtone etc but the phone is useless with the white screen. Factory reset won't help either.
Any ideas?
what lead to the white screen?
external reason - water, dropping, general impact... ect?
i don't think it would be software since you did a factory wipe and since all the other software bits seem to be working.
i would suspect that the flex cable sending data to your lcd has come loose. either from the board or the lcd. hopefully its on the board side. thats easier to fix.. depending on how comfortable you are taking something apart.
I rooted my phone and was trying to make it run faster by deleting files using Titanium Backup. I deleted some essential Google file so now i cant access the market. I don't think this is the cause of the white screen though. Every now and then the phone will boot up correctly without the white screen so i don't think its a software issue.
How would I re-attach the flex cable?
You could still try to reflash via Odin.
Ok thanks I'll look into that. Any other ideas?
flash it
Boot into recovery, usually a power button volume button combo but varies depending on device. Then wipe/reflash Rom.
Should I use RSD?
I have a motorola spice
And how do I reflash rom?

Via Odin, I am pretty sure, that there is some tutorial around here.
I found odin tutorials but none of them have a Motorola phone. They only used Samsung phones. Would it work on a Motorola phone?
Ok I think I found a way but I need the sbf file for the Canadian Motorola Spice. I have a friend with the stock rom. anyone know how to extract it?

Sadly, I dont remember the commands.
OK so I'm going to take it apart tomorrow to see if it is a hardware issue.
What's the deal with flashing a custom rom? What limitations are there on the rom I can use?
I figured out I need to install the application G apps to access the market again. how would i do that?

Download the gapps package for android 2.1. it should be a .zip. Then go into CWM and flash
sorry for the really late reply.. for some reason i only just now got notified...
rsd lite is what i used to flash my electrify. which is a Motorola. i would assume it would be the same program from you as well.
as to reattaching a cable or reseating a cable its all a matter of how comfortable you are with taking things apart. if your really nervous about it.. i wouldn't suggest doing it at all. you are going to be dealing with a lot of very small bits... well maybe not so many but there will be a few.
the tools you will need are jewelers screwdrivers and maybe some small torque bits.

Hey guys. Sorry I didn't check back in. I took my phone apart and saw that half the flex cable was ripped. My phone is a slider and the edge of the keyboard would cut a little bit of the cable each time. I replaced the cable and Motorola took care of giving me the stock rom. Guess I got lucky.
Thanks to all you guys for your help
Hello,
my phone get little wet. Water didint get inside though. And immediately i pull out the battery
Inside everything was quite dry, I took phone into pieces. (stickers are white)
But after all when I turned it on the touch is not working ;/ I do not know what could go wrong there? Digitizer looks like it is made from one piece and I would thought that it is waterproof, there is nothing to damage? Or I am wrong? Connector is also fine from both sides, and It was completely dry.
Any ideas?
There is a way to get back my contacts from phone now? And maybe some data?
I had same problem, I refresh first recovery and I put not touch, old version of recovery. After I flash rom again, and after recovery touch 4ext and phone was again ok. Try.

Nope, doesn't work ... Actually I can did also a backup (image) of the rom, but how I can extract raw data from there? Like contacts etc?

You can open the backup images on Linux and search for the files you need

with ext explorer you can open ext images also in windows or if your backup uses tar format you can open it with winrar or 7 zip

Ok phone is working. I changed the touch screen with LCD. You could ask why LCD? Because dissasembling it again I broke it a bit...
and I paid 50 euro for everything, quite expensive comparing to used working phone but... whatever, I am happy that is working now
I am just curious why this oryginal touch is not working? There is no any visible damages and water couldnt go inside.. hmm

Water can get inside very easily. Even if you can't see it, a tiny amount of liquid in the membrane between the two layers can stop it working. I work with EPoS sytems (touch-screen cash registers) and the amount of screens I have to replace because of liquid damage is incredible.

hmm now I am facing with the problem that battery drain is much higher then before (before changing screen+touch). Why it is behave like this?
Maybe I should do some calibration or so after changing those components? But touch i accurate and just fine so I do not think that I should calibrate it.
Hello, I've registered especially for that problem, so what happens is after I get the cool NVIDIA bootscreen, I instantly come up with a message saying "Turn off" or some kind of shutdown message.
Before you ask, yes, my bootloader is unlocked, and it was rooted until I do a factory reset, since it was doing this auto shutdown, I also currently have CWM Recovery, which is quite a nice recovery !
Here's a list of things I tried and that didn't do anything:
Try to cancel the shutdown somehow
Booting the tablet multiple times
Factory Reset
Also, I can't seem to use it with my computer since, well, that damn shutdown on startup.
So what can I do ? I still have access to the recovery. Could it work to give it some ADB in the tablet's face ? I really need this beautiful piece of hardware to play vidyagames.
And also, the battery is full, and working properly (I can kind of see the battery on top, it's probably at 80% or something.)
I'd also like to point out that it suddenly started doing that. And there's also a SD card in it. And also, when I access the fastboot, well, I can hear it on my computer, guess it's a good sign !
And yes, it's the one with Wi-Fi, so if I have to use a ROM, I don't think I would have much choice. Also Android version is Lollipop.
EDIT: Nevermind for the ADB, it requires my tablet to be on, at least I can still use CWM Recovery and fastboot ! yay
EDIT 2: The message is:
Power Off
Shutting Down...

So... do I have to reflash a new recovery image and put a new OTA ? Or just a new OTA ?
EDIT: Of course not.. I got it, I have to flash a new OTA with CWM right ? So.. it means that my current OTA is corrupted or something. Nice... but how do I flash it ?
EDIT 2: Ok found how, I sideloaded the OTA, which is quite a new thinig to me.. I never ever did modifications to my tablet without a tutorial, it was upgrading... so I guess that's good... And it didn't do jack s***. It stills power off... weird.

I have the same problem. I've tried flashing the recovery 2.1 files, sideloaded the 2.2 ota, etc. The last thing i'm going to try is wiping the system with trwp then installing the 2.1 recovery again.
-that did not work. I have initiated the RMA process.
Anyone has some instruction how to safely open a NVIDIA Shield Tablet ? I woud love to check if some hardware went off so I can rebuild it.
EDIT: Wait, it can't be hardware... It just can't ! Why ? Well... simply because right now i'm in TWRP recovery, everything is working exept... oh wait... CPU temperature is going crazy. 429491929 C... yep... I don't think that's right.
Ok, sorry for the double post, I know it's really bad... BUT I THINK I KNOW WHY !
Bad thing, it's the CPU thermometer, it has gone crazy.
So, I installed you know, that TWRP recovery, and I checked the CPU temperature.
Wanna know what it is ? It's hotter than plasma, or lava, or anything. Heck even the big bang.
CPU: 429491899 C.
That's right, that much, so... any idea how to fix the CPU Thermometer ? I knew it was something with the hardware. My theory is that it is not connect properly to the CPU. Since everything on TWRP is working... TOO FAST COOL! like all the apps I had on that tablet.
So here, problem half-solved. The tablet shuts down because of the CPU temperature, to prevent it from overheat !
EDIT: Finally fixed it ! ;v; Like I said, it was the CPU Temperature, since it kinda fell off my bed now that I remember, what is the CPU thermometer ? Well, it's a small bar near your stylus slot. Inside the thing, also, when you insert you stylus you insert it directly into the hardware part, next to that CPU Temperature thing, maybe that caused it, but well, basically, I opened my tablet with a cool little trick, basically, I took the back of my stylus and I forced softly on the tablet in the stylus slot. And what happened ? It opened a little ! So, what I did is slowy remove the plastic around to to not cause any crack of damage and it worked perfectly ! I saw that little CPU thermometer going off and what I did is basically push it back into where it was ! Also, the wi fi antenna is next to the camera, it's pretty small for your information ! But yeah, I putted back the plastic case after that and booted my tablet... and IT WORKED!!! It booted perfectly ! So: It was not the ROM or the OTA, it was the auto shutdown to prevent overheat. Also, it seems like recovery mode and fastboot don't care about temperature... so they won't be shutting down ! I'd like to thank the creators of that TWRP Recovery, it's the thing that helped me find out that it was the CPU Temperature ! It's also the first time of my life I touched to some hardware. And i'm really proud of myself even for such a small thing ! Hope it helps someone in the futur ! Thanks for trying to help me !

Well, I would have taken a picture, but I have nothing to capture pictures with... so.. yeah. Else I would have taken photos, it's pretty safe to open it by the way.
If the "bar" you're referring to is the one just off center on the right side, then that's where a Sim card is installed on the LTE model...

Nope, it's a sort of small bar near the camera, just on the top of it, it's made of some steel I think !
2 questions
I'm having the same problem. I already have opened the cover based on how you described it.
1. I can't find the thermometer and what kind of fix should I do with it?
2. How did you install TWRP when the device couldn't even boot properly.
Thanks
---------- Post added at 06:39 PM ---------- Previous post was at 06:01 PM ----------
I blindedly pushed some components back (dangerous) and decided to put back the cover. I rebooted and yeah, it booted properly! However,after a few minutes it auto shut down again. So I guess the theory that it's about the CPu thermometer might be true.
The question is, where is it really located and what should be it's position? Thanks.
Finally Fixed!
After several sessions of tinkering the unknown components of the hardware, I finally decided to take it to the next level. So I carefully removed the electrical tape covering the perimeter of the battery. Lo and behold - there's a white wire that is loose and I've determined its correct connection through its length.
Since I didnt have a soldering iron and I'm too afraid to use it should I have one, I used brute force connection via electric tape. I peeled more skin to secure conductivity.
Apparently, it's the connection to the CPu thermometer. When it is unlinked, it should register as weirdly high value, triggering hard reset. During the boot up and initialization, the firmware takes note of the value. After studying the behaviour of the problem, apparently the firmware in the chip also occasionally checks the temperature esp when an app is launched. This explained why I couldn't boot at the beginning or if ever boot was successful, antutu causes shut down. So as a solution, I made sure the contact between that freaking white wire and the solder placement on the board MUST be secure.
I'm using my fixed shield tablet to post here Btw. Apparently it has become faster. Antutu is 55,000. But charging the battery seems slow. I must have accidentally messed up something with the battery.
Boy I love my Shield tablet!
Thanks many many times!!
It fall down of the carpet and later that evening I noticed that it s off.
thanks the happenstance that TWRP shows the CPU Temperature it was fast located.
so I was able to search for.. and finally xda did it again..
Thanks all of you
Same problem
Well, my tablet got the same problem
Here some pictures, can you tell me where is the temeprature sensor?
Faced the same problem and I fixed it as suggested by soldiering the white wire behind the tape. Look at the picture to know where it is located.
First attachment with the tape on. Second image with the tape off and after soldiering the white wire to the board. I hope that helps.

wow ... excellent post. this also solved my restart problem. thank you very much.
interesting side-fact: this only affected stock images. all alternative roms (bliss, etc. ...) started fine ...
I've got this exact problem as well but even after soldering this white wire, it keeps shutting down..
Edit: after some more attempts, I got a new temp: 92c. But I still got shut downs.. So I managed to switch it back to that weird 42516516161 etc temperature and now it wont turn off with the Custom Rom Bliss Pop.
I had the same issue. The device started to shut down by itself, sometimes right after boot. Luckily I stumbled to this thread while googling for the issue. Then I verified the problem by installing cpu-z and watching the temperature while waiting for the device to power off. Indeed, just before powering off the sensor jumped to -46 C. So with your help I found the culprit and soldered it back. No shutdowns ever since!
Hello,
so my sister droped her phone in water and gave it to me to repair it. Because it didn´t boot up at all I cleaned the motherboard with isopropanol. After this I charging worked but I was still stuck in the powered by android screen. (The phone tries to reboot every 10 seconds or so). I did flash twrp and could save all of her data via mtp. After that I tried to flash a custom rom, a stock rom with samsung smart switch and a stock one via odin. It always did work but the phone is still stuck in the powered by android screen and wont boot up
Is there anything left I can do or is the phone lost?
Thank you very much for your help!
Looks like too much mess with hardware, do youself a favour and do not mess with it anymore and get a help from 3rd party service (not samsung ofc, they would charge you a hell of a lot)
Sounds really familiar. I do repair phones for my work and a customer with a custom ROM had the same problem. I also tried everything, custom ROM, stock ROM, update, downgrade, etc... Nothing worked. Keeps rebooting. In the end a mainbord swap was the only solution. I'm afraid , especially after water damage , this could be the case with your s6.
