Did I break my my T700? - Galaxy Tab S Q&A, Help & Troubleshooting

Hi guys,
I'm writing here to hopefully get a better understanding of what's goin on with my tablet.
It has 3.5 years. I was sending a voice message on telegram on it when I accenditally dropped it on the floor (50 cm glinding).
I'd say I broke some hardware component but i'm not sure it's the case.
In fact, right after it fell, I picked it up noticing there was no visible damage and it was still powered on. I have had just the time to quit telegram, realizing the touch was still working, when it turned off (it was charging).
Now:
- I'm able to access recovery and read the memory via its file manager when IT'S charging..but I can't get into the rom itself (it would just show me the battery charging icon).
- It won't boot to anything, neither recovery, when IT'S NOT charging.
It's pretty sad cause I recently gave it a new battery,book cover,screen protector and rom with new kernel and customization stuff u know..first time it drops also...
Any ideas?
I'm aware it's not 100% correct english, hope it was clear anyway. Thanks for reading anyway!
Greetings
EDIT:
I replaced the battery (which I swapped months ago) with the original one and now it's working fine!

Artemis white screen + screen shaking problem

hi all gurus,
my artemis recently got a white screen of death..
symptom
- the whole screen slowly becomes white
- will happens especially in hot (outdoor, noon time, or when loading big programs)
- the phone itself is noticeable hotter than normal when white screen happens...
- need to unplug the battery in order to restart.. soft-reset wont work when screen goes white..
- at early stage, still can connect to pc and flash new ROM, but now, cannot connect to pc already (pc just wont recognize it)
- the screen is seems to be shaking left to right all the time (a noticeable extra 5 pixels appears on the left most border of the screen, and the goes disappear, repeatingly)
- have already replaced a stable and clean ROM at the stage were the ppc still can connect to pc (i use the ROM before for few months, no problem)
- have try to switch on with a new battery, problem remains..
- battery drains quickly...
does anyone face this kind of problem before? it is hardware problem right? i search on the time, some says is the CPU need resoldering, some says need to replace the LCD ribbons... but the unfortunately things is, no pda repair expert near by area...
any feedback is apperciated. Sorry if my english grammer is not so good.
thanks.
i have the same problem...
i have bought a new battery and it still happens.
I now only get the following on boot:
IPL: 3.04.0001
SPL:1.11.0000
GSM: 03.08.90
I don't get the fourth one and it no longer loads - does this mean that the os is fluffed..?
Had the same problem, hard reset solved it

Hi...
I had the same prob. as in first post here...with my aretemis.Tried to fix it (after i ve read sh... load of threads) by heating up board and CPU (I was pissed so I just wanted to destroy it) and I managed to do so.
Now I get only red led when it is con.to PC.
After that I found post of some guy from ROMANIA who claims that he managed to fix it by one of these:
1. reheating CPU
2. changing CPY clock crystal
3.(I can't recall third thing, but it was hardware too)
After that I went on eBay, got a better one and now I'm happy with my new artemis,plus I have spare screen battery etc..in case I damage it somehow...
Ah yes...before I tried to f...(fix) it, I found that my warranty is expired for 1 month....so you can imagine why i lost my patience.
i know this will bring you down,sorry,but I had the same symptoms...
now I'm changing custom roms to see which one fits me, and still i get amazed with this beautiful phone....
cheers,
Z
Looks like a general problem with no fixes/solutions to be found anywhere.
My solution:
Get rid of this HTC sh!t and roll back to Motorola...
Found a solution!
Still being under manufacturers warranty, I took it to the repairs agents, they replaced the motherboard and voila!
Never blame a WSOD on software...

CDMA galaxy nexus - unresponsive to touch

Hello everyone,
Basically went to unlock my phone today and touch screen is not responding, however the hardware buttons work fine. Now i've done some research and found other posts of people with the same problem, however their touchscreen problems seem to be fixed(temporarily, at least) with a battery pull.. mine however is still unresponsive after half a day and multiple battery pulls.
Id rather not have to send in for certified to replace an otherwise perfectly working phone.
Any ideas/suggestions would be greatly appreciated!

are u undervolting?
Nope, sorry forgot to say. Completely stock never unlocked or rooted.
Also i tried getting into recovery to try and do a factory reset but when i select recovery i just get the android on his back with the red triangle..
so instead i just went through the steps and unlocked the bootloader and booted up (in order to give me the factory reset without having to touch the screen)
It unlocked and booted up fine but still no response..
No new recent app installed and never had this happen before.
Mine did this after a few days of owning it, and luckily the store took it back and swapped it out with a perfectly working unit. Is yours within a few weeks of purchase?
Figured this out randomly. Remove battery cover. With phone turned on, press on the area to the to the left of the camera lens until the screen is responsive. My screen becomes unresponsive when the phone is dropped and this fixes it.

hrmm this does not seem to fix either. I also have never dropped my phone, although this seems to be worrisome if the issue is hardware related.
@ tmellen i purchased the phone from amazon and am a few days past my return date :-/
Guess ill just give them a call and hope for the best. Thanks for the ideas everyone.
(update) called amazon and they are sending me a brand new phone.
Knowing this i thought i'd try dailong's method again only this time i was quite a bit more "rough" with pressing down on that area, and it actually worked!
Ill still be taking the new phone once it gets here but for anyone who is having this problem there's a sweet spot on the left edge of the phone towards the top (looking at it with the back cover off) there should be a circle shape. press on that area really hard and it should fix.. weird
Experienced the same on my GSM version a few minutes ago. I had to call my mobile to get it to respond. After that it worked again as normal. I'll see if I get this issue again in the next few days. Hope it's just random
Had the same happen earlier to mine and I was on AOKP. I've had this happen to other phone before, shouldn't be a a cause for alarm unless it happens very frequently. Btw, next time it happens to me I'll give that left side of the camera trick a try.
mine got fixed by removing battery.

Black Screen, phone still works?

Hello XDA members, this time I'm writing to all of you to tell you something that happened to my Optimus G E987 from Claro Argentina, also, to ask you something related to the topic.
I bought this phone about 4-5 months ago, and I have taken really good care of it, without using any film protection or case, it was working perfect and with not a single scratch on it, not even a little hit.
But then, some days ago, I decided to "protect it" a little bit, so I got one of this:
htt-p://i[dot]imgur[dot]com/YtgK1aS[dot]jpg
htt-p://i[dot]imgur.com/la1kI5e[dot]jpg
(Sorry, I'm new to this forum so it won't let me post links)
I used it like.. dunno, 3-4 days. One night, my phone was on 53% battery, to lazy to charge it so I just let it like that. Next day I gave it some use, so it dropped to 33% of battery life, I had to go work so I turned it off. When I finished, I tried to turn it on again, but nothing happened, tried more times and nothing, then I noticed I liiiitle light in the screen, the phone was turned on, but with REALLY low visibility, almost everything black but with a little of sight.
I though it was just a battery problem, so I charged it, but to my surprise, nothing happened, well something did happen, the little bit of sight that I had just went full black with no visibility. I noticed that the touch screen and buttons actually worked, I could "easily" navigate through the phone by just using it as normal, but without seeing (you can do this by just knowing your phone a bit).
And that's the story, basically, after using that case, the phone "casually" stopped working properly, all I got was a functionally phone with a black screen.
I managed to connect it to my pc through wifi and launched Android Screen Cast, to see what was happening on my phone. The glow was at 100% (I tried changing it) and everything seemed normal.
If you don't want to read, here is a TL;DR
>Bought Magnetic* Flip Stand Leather Wallet Case for Optimus G
>Some days after, phone screen stopped working (phone was still normally working, just with a full black screen)
About the Magnetic thing.. is there any possibility that this was the problem? the magnetic thing?
Btw, I sent the phone to tech service because it was still on warranty and they have me a new one, now I'm scared of putting it again in the leather case I bought, I don't want this to happen again.
Something to comment? hope you can give me some advice, thanks in advance!
Also having similar problems as you. Somehow, i am quite sure its the stock rom causing the problem.
Had the very same issue few weeks ago, had to send the phone back to LG ( who replaced the motherboard :/).
I was also on stock rom, had root and unlock bootloader (of course I clean all that **** before sending it back).
For my part, I was unable to go to recovery and download mode was quit impossible to access (may be my finger fault )
BUT! some time if I let the phone off for a moment or spam the power key, the backlight turn back on until I power down the phone, so it's could be a software issue ...
Anyway, an other info, when the backlight was off, if i tried to change backlight level i was getting a error message about overeating or something like that...

WiFi is gone

I've had this tablet (SM-P600) for almost a year now & it has worked perfectly. Over the last week or so, the WiFi has been randomly turning on & off. Not just losing signal, but actually showing as off in the menus. As of this morning, wifi will not turn on at all. Just says "turning on" on the screen & sits. Never gets to the next screen showing all the open networks.
Everything is fully backed up so I went into recovery tonight. Did the full factory reset and wipe procedures. Tablet boots back like it is as supposed to, but wifi wont turn on when getting to that screen in the initial setup.
Tablet has been well cared in a case, not dropped, and not gotten wet. However I am still positive this is a hardware issue.
Any ideas for things I might try? Help!! Thx in advance
I've the same problem with my galaxy note 10.1 2014 edition SM-P605 :crying: Still haven't found solution
I am almost 100% certain this is some type of hardware problem. I tried flashing about 3 different ROM's and 3 different kernels, all of which successfully booted up. I finished by doing a 100% re-wipe (data & system included) & reinstalling a pure stock kernel and firmware. On every single revision, the words "turning on" would appear when clicking the WiFi option, but then it would get stuck. Message would eventually clear & I could continue using everything on the tablet . . . . . . . just no WiFi or Bluetooth functionality.
Final attempt was to gently remove the back cover. When lightly tapping around different points on the MoBo, the names of my local wireless networks would OCCASIONALLY appear. At one point they locked in & I really thought I had it. However, the whole thing disconnected again after a few minutes & I was back to square 1. :crying:
I never could figure out the perfect sweet spot to pinpoint the problem. My guess now is either a chip or ribbon cable that isn't seated properly, but I poked and pushed (gently!) on everything that was visible without removing any hardware other than just the back cover. Does anyone have a link to the layout of the motherboard that shows EXACTLY which piece is the WiFi/BT module? I did find an online disassembly tutorial with a random Google search, but for some reason they failed to identify this particular module.
Sorry for the long post, but I feel I am SO CLOSE to figuring this out once and for all. Just need a little more tech help to push across the goal line. Thanks!!

Sorry about that. It's just the initial release plain jane WiFi model. SM-P600
Update:
After a little more poking and prodding on the MoBo, I'm starting to see activity. Tablet will finally connect again, but will only hold the connection for 10-15 seconds and then drop back out. A few seconds later the cycle repeats.
I really wish I could find a good hi-res photo of the motherboard to help. HAS to be a simple loose connection, or maybe a not-so-good solder point somewhere???

never heard of 'em, is it a cheapo tablet? In my country there's a store of them (Allwinner 6.6" tablet with microSD slot, 2gb internal w/o bluetooth WIFI ONLY INTENDED FOR CASUAL GAMING, or should I call it kids only tablet, RM130 ($35))
That thing has a cheap plasticy housing, unneat design but has a pretty good performance (it plays dead trigger pretty well)

SM-P600 is Samsung's actual model number for the WiFi only version of the 2014 Galaxy Note 10.1. Most definitely NOT a cheapo tablet!! Although this wifi issue makes me wonder. I had the functionality back for about a day or so, and then it disappeared again. This has to be a simple case of a loose connector, but I sure can't find it. Ugh. Utterly frustrating.
oo...my bad
maybe software issue
This was sent from my Lenovo A850 via XDA mobile app.
What firmware version are you using because I am having the same issue. I manually updated to the september update (P600UEUCNI1) for the wifi version and started experiencing the same issue.
Same here. I think it's an issue with NII firmware.
*****PARTIAL solution*****
I have proven 100% that mine is problematic hardware . . . . . NOT software or kernel. For the time being my WiFi is back up & seemingly stable. I had to remove the back from the tablet for the fix. You have to be *extremely* careful, but it just snaps off with no screws. Lots of YouTube videos if you choose to attempt, but please don't say I didn't give you fair warning!
The reason I say partial solution is that I haven't pinpointed the exact location of the short. I am 99% sure it is somewhere on the extreme upper left hand corner as you face the front of the tablet. There are a couple of ribbon connectors in that area, and a few snap on type connectors that look like little motherboard chips. After gently poking & prodding the ribbons and disconnecting & reconnecting the snap connectors (being CAREFUL; I cannot stress this enough), my WiFi reappeared.
My final tip is to keep the screen on the page that shows the list of available networks. If you are having the same problem I was, this screen will just show "turning on" and nothing else for the WiFi. While poking around, I would occasionally see the list of networks pop up & then go back off. I finally hit whatever the magic spot is, and the networks held. Snapped the back cover on again, and I've been online for probably 4-5 days now without a single hiccup.
And before I get flamed, I know how dangerous it is to poke around with a powered, exposed tablet. There are probably certain points that could make connection and FRY the entire thing in an instant. I was just willing to take the risk as my tablet was useless without network capability. I had nothing to lose. I would recommend at least trying to poke & prod with the tablet OFF a few times to be safe, but I personally got tired of rebooting over & over & over & over. My luck sucks. With the tablet ON, I was at least able to monitor when something was happening.
Good luck if you attempt it!!

I bought my Note in March of this year, I started having the WiFi issue after the April firmware update. At first I would get the Connected to... message at random times, even though I had full signal strength. At the end of September, I started losing connection at random times and in the middle of October, I had to send it in to Best Buy's Geek Squad service to have them repair it. It is a hardware issue, as the no matter what firmware version I use, it will never connect to the router. I know it, Geek Squad is aware of it, as I have sent it in for repair twice so far. I would have to send it in a third time before they will think about replacing it with a new Note. I will admit, that before I updated it in May, I did root it, because I tried to remove the Business Week+ and New York Times apps, as I never used either one of them. I tried disabling them, only to have them reactivate and update themselves.
Damn, what I read here is not good news. My SM-P605's died yesterday.
With Tapatalk on my Galaxy Note 10.1 (2014)
Hardware issue for sure. Same problem with mine. Opened the back case, disconnected the upper right (as your looking at the screen) small ribbon, reconnected, and boom, perfect wifi once again!
The EZ Package Disabler app is fine for debloating rooted and non-rooted devices with Touchwiz roms. It uses Knox, so that mustn't be removed. The apps are still on the system partition, but are completely dead now. While other apps, especually for non-rooted devices kill the system apps during boit and try to prevent their restart. But during boot the whole stuff is active until the app kicks in, allowing the system apps to receive updates, communicate, spam free flash mem etc.
The app wirks the same way on my rooted P605 and unrooted S5. And gives a reason to buy Samsung stuff, unlike Touchwiz and its bloatware. As far as custom roms go, i found that of my old LG L9 much better. Even if the early roms were AOSP 4.0.4 based, then 4.1.3, they had already had the fresh & bright look & feel of the future Kitkat, and a few useful enhancements like an integrated backup tool, which was more simple, but for me as useful as TB.
As for the main problem here, i think using a case with a hardened backside, and not one if these with a big hole(though being better than nothing), prevents oroblens like battery, display and seemingly wifi connectors loosening. Or bad solder joints. The backplate of the note gives thru any pressure on the back, especially in the middle area. It then rests on the battery, metal shields, connectors and stuff. This seems to generate enough wear over time for problems. The same back plate on a much smaller device(my S5, but that has a subchassis covering the innards, too) would be much stiffer, and my 7" tablet has an aluminium unibody case, such trouble is unknown there.
Hi Gents..
same problem here... I used to own a SM-600 purchased in 2014 unfortunately I lost it... (the first tablet worked without any proble until I lost it...) than I managed to found the same modell brand new on amazon... it worked for 2 weeks and 2 days ago wifi died... but funny enough not straight away.... first couple time just switched off the wifi... I managed to switch simply back... next day it only worked if restarted the device... now factory reset nothing... If it is hardware related why worked 2 weeks witout any problem? If it is software related why not working after software reset? Only installed a few apps from the store.. the device did not overheated or physically damaged...
I have the exact same problem.
Since I bought this a long time ago, I have to pay for the repair. I just want to know if it is worth it. How much did it cost you (if you bothered)?
In my opinion it would be foolish to spend a dime to repair a 4 year old tablet. If the battery is original, it may well be near the end of its useful life as well. FWIW, I bought this tablet used about 8 months ago and have not experienced this wifi problem.
It's still so well equipped, that you can't simply replace with a modern entry level or midline tablet, but with a top of the line one, so a repair is well an option.
I just don't have a clue about the SoCs performance level. To which current ones it would equal and where things get better. I can only compare it to my similarly(Snapdragon 801) equipped phone and my cheap 7" tablet's quad core Mediatek SoC, and that is considerably worse, though being three years newer.

LG G3 (D855) Blue Screen of Death

Dear community.
A few weeks ago I rooted my LG G3 and installed Fulmics 6.0.
Everything went as planned and worked seemlessly.
Today, while watching YT-videos my device turned off and tried to reeboot. After the first, non-animated LG screen, the blue screen appeared.
Same to say while trying to boot into TWRP recovery. After the blue TeamWin Startscreen, the blue screen shows up again. :crying:
Is there any help left?
Kind regards
Thomas
My friend also happen problem
He asked people to help take
Finally, open the motherboard
Then take heat
That seems to be a common problem LG G3
Welding where welding is not good
PS. I use google translate
hi guys, i had the same problem now for 2 days searching the forums for any sign of hope even ringing lg them selves to for them to tell me the repairs will cost more than the phone
so i new at this point i had nothing to lose.. after playing around for 13 hours with my phone i have got it all up and running at the minute for a full day an not once gone off so i might be the lucky one buts its worth a shot
this is what i did.
disassembled my lg g3 and took out the logic board
took off both heat i/o sheilds from the i/o
with a fine tooth brush and some contact cleaner (ipa 90%) i cleaned the main part of the board and let it dry out half hour
i then applied hot air onto the board both sides and let the contacts reseat them selves and the put phone back together (make sure you out the i/o shields back on)
i then tried resetting my phone with lg flash tools and the correct fireware for my phone
(when you are cleaning your phone there is a little sticker on the chip stating what firmware you phone came with, find this firm where as you know it will work)
anyways it didnt work for some random reason so i tried lg flash tools 2014 (i will link everything below).
so when i found the correctish .kdz file i flash the firmware making sure everything went
and for the first time it went to 100% first time.
played with my phone for a while all seamed ok wasnt the standard firmware what was on when cam out the factory.
so i then tried lg flash tools again with the correct firmware and it worked spot-on and has never played up are missed a beat since....

Just an quick update the phone is still working like a dream. Also upgraded to lasted OS. So this could of been a lucky fix or just a bad section in software.
Sent from my LG-D855 using XDA-Developers mobile app
I actually just got this yesterday, and fixed it. It started blue-screening and rebooting sporadically but quickly got to the point where I'd turn the phone on and it would blue-screen and shut off after two seconds. I could still hold Vol Down and power to get into the STOCK system recovery screen, and by choosing Safe mode (Factory data reset went to blue-screen) it went into TWRP. I tried a whole bunch of different things (and luckily was able to get a backup of the internal storage to my SD card) before doing a full wipe. FULL wipe. I then flashed the stock image via KDZ which is where I sit right now. No blue-screens. I had been on Jasmine 9.1 and Skydragon kernel, I'm thinking maybe a recent update didn't play nicely with either of those, or maybe some other custom firmwares too.
I also got this and somehow i manage to resurrect the phone. I was installing another stock-based ROM (Zoe ROM 3.0 - based on V30N) and after setup my phone got a blue screen. I unplugged the battery, i tried to start it again but only showed LG logo for one second, and after that was dead. I mean, completely dead. No power, no charging, no PC detection, nada!
What I've done:
1. disassembled the phone and pull out the motherboard (G3 is really easy to disassemble, really);
2. open the protective cover near the CPU/Memory (it's a weak metal cover, easy to pull down);
3. i wiped gently with a toothbrush and alcohol all the components (i put a lot of medicinal alcohol);
4. i used a hair drawer (hot) to clean the excess of alcohol and to heat the CPU zone (about 1-2 min);
5. i assembled all back together and i prayed to God (no joke, believe it or not);
6. after that i pressed the power button + vol- (to enter recovery) ... and surprise, it's alive;
7. i restored a anterior software backup, just in case... (now i use Zoe ROM 2.7 based on V30J);
Now it's working for about ~4 hrs and no problem at all... i will edit this if something is happening.
Good look! And pray... sometime it really helps.

I'd suggest flashing an original factory image and re-rooting / re-installing TWRP.
Worked for me also !!! Without praying

i then applied hot air onto the board both sides and let the contacts reseat them selves and the put phone back together (make sure you out the i/o shields back on)

This worked for me! Didn't even need to reset the OS. My wife's G3 shut down on her one day. I started trying to fix it, but couldn't get past it showing blue screen, boot looping, and then going dead to the point where it wouldn't even boot to the flash recovery screen. I couldn't even get it to turn on at all until I took the battery out and held the power button down for 20 sec.
Then I read this post, removed the circuit board and shields on both sides, blow dried on hot/low setting for about 7 min each side, and let it cool off for about 10 min, then re-assembled everything. First boot it went right to the PIN lock screen like normal. So far so good it's been running for about 30 min no issues. Thank you!
Glad it's working mate I got my phone to my little one now and still going strong it did have a little TIFF a few weeks ago with not even turning on but left on charge for a day as for some reason the battery drained that much it couldn't even charge so yeah
Yeah just did a drop test and smacked it around a little, so far so good still going...
I have a solution to this problem.
When you disassembly phone and remove protective cover (from processor site) remove little battery from motherboard - near to processor.
Thats all. G3 is back to live (at least mine)
The bsod happened to me as well. After trying everything, flash stock firmware, boot to recovery and wipe data, cache etc and nothing worked. I then disassembled the phone and put the motherboard in the oven at 180degree for 10 minutes. So far so good, it booted up fine and it's working pretty well till now. Flahed v30b version and it's working since 10 hours. Will report back how long it stay alive eheh

Looks like this disassambling things really works cuz i read so many places and heard from friends that it works.
But really strange why it suddenly started this problem on everybody
I solved the problem by putting CPU limit. It is not a good solution while your phone works as half of its potantial but it works. Maybe one day i will bake it too
Here's another proof that the heatgun solution seems to work.
My G3 was randomly crashing from time to time over last month but the bluescreen appeared for the first time today. Since then it didn't make it past the LG logo before it would turn blue and shut itself of. So same problem as described above.
I took it apart and took of the metal "heatspreaders" from the motherboard, then heatgunned it from both sides for like two minutes each (with waving the heatgun around so I wouldn't burn the entire thing ), let it cool down a little and reassembled it.
I then just powered it up normally and it works just fine.
I'll update you in a few days.

Yeah, it works, in most cases. The question is - for how long... You may be lucky, and it could be a permanent fix for you. However, the nature of the issue is a manufacturing defect which can only be fixed for sure by reballing the chip (or by just replacing the whole board). Going a bit deeper into technical details, the chip in question is a BGA type (Ball Grid Array). It means that it doesn't have traditional leads for soldering on the board (the ones that are either sticking out or just located on the sides). Instead, it has soldering pads on the underside, and the soldering is done by putting a pre-arranged set of solder balls (hence the name), and the flux on the pads, and then heating up the assembly until it melts. A flaw in preparation or in the soldering process itself results in a bad contact on some pads which usually manifests itself either after the chip and board heat up under load, or when the board is physically deformed even a tiny bit (hit or dropped), or just after some deterioration/oxidation over time...
Sorry for the nerdy stuff, I am done now... Basically, consider the heatgun trick to be about the same as banging on the side of the old tube TV trying to fix the static on the screen...
