Dear folks,
One night I reached out my hand while sleeping, touched a glass of water (which fell over) and my Galaxy Nexus GSM got wet. In the morning I dried it (*no* hair dryer, just a vacuum cleaner and a radiator), and it still works like a charm. With few exections: Almost no signal anymore. Most often no signal, sometimes weak signal, rarely full H+ speed.
In my flat I have no radio at all (-110db if that matters). No speech, no data.
Outside I may have luck, I may not. Sometimes I get almost full HSDPA+ as stated, but most of the times with "standard" covering just no signal or a really really weak one, where my old HTC Hero (T-Mobile H2 Touch) and my work phone (Nokia 31xx) have full(!) radio signal. Embarassing.
Speaker was damaged, too. So was the USB port (not charging when switched on, no sound, wrong headset recognition).
I decided to repair it myself. I did this before many times with my old Nokia 3310, and ifixit.com suggested, it's not that hard. So I went to eBay and bought a new speaker part (that more bulky part at the bottom of the disassembled phone).
Well, this fixed the speaker/headset and the USB issue. Hooray! But my radiosignal was still bad.
So today, I replaced the antenna mainboard (L-Shaped). Well, this fixed… nothing at all. I still got bad radio (at least it's not broken down completely). Now I wonder: What could I do next? Flasing radio firmware has no effect either (I think, I tried three or so). Is it really because it got wet? Sth else to replace?
I'm looking forward to any suggestions on what to do next. If you need any information, just ask.
Thanks in advance.
I'm sorry I can't provide pictures atm, but I only wrote 5 posts or so.
Hey guys, like many Toro owners, I had my MicroUSB port finally go out on me. Followed unfortunately shortly after a tumble caused by a cousin just giving my phone to her 3 year old to play with at a family holiday party. This resulted in the screen being cracked all to hell, as one could imagine. In a stupidly rushed attempt to repair the screen glass with a spare piece I had from a friend, I messed up the digitizer, and decided to get a new screen assembly and start over. Unfortunately, after ordering both parts and starting to install both, I realized the mUSB board was no good and had to be exchanged. I slapped the old one back on, installed my screen, and went about my day.
The second time around, I actually remembered how to work on computers and went through my whole usual litany of prep and breakdown. Bled off all my static charge, made a mostly sterile work area, worked in gloves when I could, and proceeded slowly and carefully through the phone teardown. I made sure (to attempt) not to damage any ribbon connectors or even the LTE antenna coax cable and both ports for it.
All this only to notice a short time later that I was having poor call quality, call drops despite a couple of bars, random signal drops, all those good times. This was all with mobile data turned off entirely, but when I turned on mobile data, it hit straight to 4G full service and data was snappy and page loads/searches were fast. However, I cannot tell if it is area signal strength or phone error, but I'm inclined to believe I may have messed something up either in my first botch job, or in my second serious repair.
If there was any repair errors, I'm inclined to believe one of a few things happened. Either I screwed up one of the in-frame antennas the first time around, putzing about trying to pry the old screen off the frame. Or I somehow cocked up one of the CDMA antennas on the mobo itself the second time, but I find that very hard to believe. Or the old mUSB board with it's mic got screwed up, but I highly doubt that too.
Anyone have any ideas, further questions, or (preferably non) snide comments? I've tried to give as many details as possible in this post without overloading it, but let me know if I've left out anything useful. Yet again, it's a Toro, 32gb, running SlimKat's 4.4-1825 weekly. (Can't remember build date right now, and phone's in pieces again for visual verification/pictures)
Any help is greatly appreciated, and thanks!
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.
so today I got this strange headphone jack icon on the notification bar for no reason: I hadn't had headphones in the phone for weeks, and it popped up. I tried restarting, shutting down and turning back on, and finally trying headphones and taking them out, and nothing works. What's the deal? I also notice I can't play my music anymore without headphones. Could it also be I might have accidentally gotten some snow into the jack? Where I am now, snowy as hell, earlier I was outside and was cleaning my car off, and had to take out my phone.
Can someone help me!!!! I can't even talk on the phone without speaker!!!!! Pleasseeee
And if that could have been in all caps, it woulda been. I need help quick goddammit!!!!!

Hi I had a very similar problem recently, searched the web through and through but to no avail? It happened to me after the phone took a drop luckily there was no visible damage and I managed to get my carrier to replace it for free. I do believe that will be the only fix for this.
Good luck, if you do somehow find a fix it would be great if you could share.

Luckily, just as I walked into the ATT support center, the icon disappeared. But I still had them use the air can on it. Lesson learned: be careful when taking your phone out if your gloves have any snow on them whatsoever.
I dropped my honor 8 pro in water and it was been dead for some time, around 15 days. then one day I tried switching on and the power came on. I could make calls or receive messages but the camera and the fingerprint sensor were not responding. But when the phone goes into display off mode the display doesn't turn on again, unless I restart the phone. But the phone ringed if any call was made ,since the screen didn't display i couldn't receive the call.
So, gave it to a service center where they kept the phone for a month and then when I called them after a month they said the motherboard is dead and it will cost me 20k for a new one. i smell something fishy here. was my motherboard really dead? if so how come i could switch it on and even make calls? and why did they take 1 month to make the diagnosis? and does the honor 8 pro motherboard cost 20k?
please help.
Chances are high in motherboard damaged when drops in water . They will test in various aspects so it may took time nothing is fishy u purchase a new mobile rather giving 20k
Motherboard has all the parts attached one or the another way, they are may be right. Don't waste 20k on dead phone. Go for new one.

New phone is available in 20k ... Dont waste money
I had something similar happen to my phone it got water damage and went in lock mode 20 days later turned back on everything fine but a few days after wifi and booth stopped working in my case I would have to replace the wifi and Bluetooth module on the motherboard which is extremely hard to find for some reason, however, in your case, I think since u sead the phone still works, it just has calls problems u only have to change the communications board which tends to be a lot cheaper then the motherboard in most smartphones hower again this component is really hard to find and therefore can be quite expensive because there is a very low supply compared to the demand which is not huge. however, one thing that u can try which is not guaranteed to work but has a 50%chance is a chemical bath which the will provide in some phone repair centers
