Anyone know the validity of this? It is 9months old.
I've heard of that, even though I haven't been through it personally. I've also heard companies are easing up on phones being sent that are rooted so I don't know, probably just depends on the tech you get I think. Plus, only takes a couple mins to unroot your phone anyways for warranty purposes.
Generally, this is the assumed response for most carriers. Even though sales reps for some carriers are totally cool with you rooting your phone (like mine, for example), they'll still advise you unroot, since there are "no guarantees" that they can help you if you're still rooted.
In some cases you'll also have to reset the Download Mode counter (viewable by restarting your phone in Download Mode and looking at the counter on it). On certain Samsung phones (like my Epic 4G Touch), this involves using a "jig" that bridges pins 4 and 5 of a Type B Micro-USB connector with a 300-301K resistor (you can get a premade dongle for about $5 US on Amazon, or build it yourself with a Micro USB breakout board and an appropriate resistor).
If you're trying to troubleshoot something, one of the steps is to return to stock firmware/kernel/ROM/etc. and see if that fixes the problem; if it does, then a bug in your particular modification was the problem. If it doesn't fix the problem, then at least you're no longer in violation of warranty, so the manufacturer/carrier can fix it instead.
Hello all. Long time reader, first time poster here on the forums. I thank anyone in advance for assistance.
I just received a new Mophie Juicepack for my T-Mobile Galaxy S3 (non LTE). Charged it up and plugged it in and not working... In my efforts to diagnose the issue, I have verified the following:
1. The case does in fact hold a charge and is able to charge up an identical T-mobile GS3 (my girlfriend's) using the stock rom, unrooted, untouched really.
2. My phone has no issues being charged via numerous USB cables plugged into wall chargers or directly into the PC
3. I am even able to charge the phone using a 1700mAh external micro usb battery kit.
So the only variable that I can come up with is that it must be a software issue with my phone (since both my phone and the case function fine in other conditions). I have attempted updating my ROM to the latest stable Cyanogen Mod version, (10.2.1-d2tmo), wiping my cache, wiping cache with a factory reset and reinstall. I have also tried the latest stable AOKP ROM with no success...
My analysis leads me to believe that maybe there are some settings somewhere in CM that alter the conditions in which the phone will receive power. I imagine this would be some sort of terminal action or manually modifying the root files as I have searched the phone's menus a thousand times.
Does anybody have any ideas on how to solve this issue?
Has anyone else has issues with external batteries while running custom ROMs? Or with Mophie cases in particular?
Any help would be appreciated. Thanks!
I'm currently on a Moto x (2013), coming from a Galaxy Nexus. I switched because I needed a faster phone, and the GN hardware is just too dated. The moto x seemed perfect, until I found out I can't tether, root, or unlock the bootloader to save my life.
That being said, I'm in the market for a Verizon S3, which will likely already have 4.4.2 installed. My main concern is root access and native hotspot tethering (unlimited data). The following are what I have found thus far:
1) root: http://www.andromods.com/root-unlock/sch-i535-vzw-galaxy-s3-kitkat-rooted-nc1-ota.html
2) tethering: https://www.youtube.com/watch?v=PxBRrsucdLo <---- the guy who created the vid doesn't have VZN, so was hoping someone here can verify if that works.
3) bootloader: I found nothing on unlocking a VZN bootloader, but this is the least of my concerns
4) ROM: http://forum.xda-developers.com/gal...nt/rom-superliterom-v1-0-i535vrudne1-t2805797
My assumption was always that an unlocked bootloader was necessary to flash ROMs through custom recoveries. I'm unfamiliar with safestrap, but I'm all in for a bit of reading and enlightening.
Again, I don't necessarily need a custom ROM or bootloader. My main concerns are still tethering (main priority) and root access (second priority)
Thanks all, and I definitely appreciate any help at all!

Root is still possible. Tethering *USED* to work on stock by using the FoxFi app. I haven't tested it in quite some time though. There's a limit for the free version, use it for testing though.

Do tell how. Especially if you did start with a Verizon galaxy s3 sgh-i535 that was not rooted and was running on stock Verizon Android 4.4.2
To clarify, I bought it set up this way. I knew clearly well that I wouldn't be able to get any of this with stock 4.4.2.
On the other hand though, the camera won't focus correctly when taking pics, and the charging is ridiculously slow. My only two complaints

Hey Rice,
I'm still on the GNex, but my wife just offered up her old GS3. It's still on 4.1.2 unlocked, rooted. I'm working on bringing it up to speed...still reading....
P.S. Is there no kernel fast charge option?

I remember seeing you around MWs FML thread! 5.0 is looking decent over there, so I'm very happy for them.
If you get the chance, I'd definitely recommend CM11. It make me feel like I'm running a nexus device again, except significantly faster than the gnex with a better camera.
Regarding the charging speed, I don't think it's a kernel issue. With the phone plugged in, I keep getting notifications that it's being disconnectedAnd reconnected spontaneously. I've done some reading and and it seems there is a bit of oxidation or hardware issue within the charging port. The port also requires soldering of the mother board to change. I've resorted to ordering some qi chargers[emoji106]
As for the camera, this seems to be an old issue of cm11. I flashed a camera fix zip, but to no avail. The focus issue seems to be problematic only at macro distances though. I can't find a fix besides touching to focus prior to taking macro shots

Don't want to start a new thread even though the title is irrelevant at this point, but was hoping someone could chime in regarding the camera auto focus issue. The camera focuses beautifully when I touch the screen, or when I allow it to autofocus. When I proceed to take the pic, it will try to focus again and take the pic right as it's completely blurry. This happens on both the stock CM11 camera and google camera.
I tried to flash the zip mentioned here http://forum.cyanogenmod.org/topic/85493-camera-wont-focus-cm11/ and nothing has improved.
Does anyone have any insight about this? These symptoms are identical to what many have mentioned in the thread above, so this is certainly not an isolated incident. Thoughts or input?
Who reads titles anyway?
I flashed Slim, and messed around with the camera a little, but I had wifi issues and am in the process of flashing cm11 11-09.
On Slim, the camera seemed to work fine. I took some "macro-esque" shots of text that came out pretty good (at least as good as the GNex, if not better).
I'll let you know how it fares with cm11...
So far, camera FCs on hitting the "No Thanks" button for location reporting.
OK, Camera is now functional (probably didn't wait long enough for the phone to settle on initial setup). The quality is mediocre. I'm still messing with it and will report back.
switching phones, want to keep/root the old Galaxy s3 as a lab/toy
Have an old Verizon Galaxy S3. Just got a new TMo Sony Xperia Z3 (which I am liking so far).
Will soon disconnect my Verizon service. Would like to root the S3 and use it wifi only as a experiment/toy thing, since there's no trade in value (cracked screen).
Possible? Cyanogenmod recommended?
I'm a total n00b at all this, and would steer totally clear of it for my main driver. But since I don't really NEED this phone anymore, thought this would be a safe way to dip my toes in. If I brick it in the process, no great loss.
Any advice or links would be much appreciated. Definitely want it to keep working as a wifi device and not brick once I cancel my Verizon service. Would be cool to be able to play with some of the fringier apps that require root. Those are my only requirements. Camera, cell service, etc all unnecessary. But do need wifi and don't want to create a big vulnerability to the rest of my home wifi network from this device once I'm done.
Thanks again!
evbb, depending on your current OS version, you might be able to root. If you are on the most current official OS, then you will likely just be staying with that.
Rushead, any update on how CM11 11-09 is going? If everything looks stable, I think I'll make the jump to that build.
Update about my charging times: The phone seems to charge at a normal rate if I use a 12V car charger made by Griffin (item does not specify amperage). I don't believe amperage has antying to do with my situation, as I've been yielding miserably slow charge times with the Nexus 7 (2.1 amp) charger. The phone is also very picky with cables. I've used 4 different AC adapters so far in different combinations with 4 different USB cables. I don't know what to think of my charging situation anymore...
When my wife had the phone it was extremely loose as far as cables went. I could use virtually any cable whereas my GNex is super picky.
I haven't had much time to mess with the camera yet. I'm using it as a WiFi device, too, so I can't comment on data, signal, etc. But so far it seems pretty stable. The battery drain is excessive imo. On standby for most of the day, battery was dead by 10pm. That's factory kernel.
For those looking for a decent tethering app there's one on sale, free on the Amazon app store. Easy Tether is the name of the app. It's free 11/14 & 11/15

You should try a very specific type of cable. The problem is the fact that you use a data cable at all. What I use is an aftermarket universal USB cable and it has the detachable tip for other phones. What this does is force the phone in "Charging (AC)" mode no matter what charger you use. Attached are 2 pictures to help identify exactly the kind of cable to solve your issue. I can charge my 7000 mah battery attached to my phone in 5 - 6 hours. A 2100 ah battery should be 1 - 2 hours with this.
Sent from my SCH-I535 using XDA Free mobile app
Some chargers identify as a USB hub rather than an AC adapter, and others do not. This is why on some chargers, it still charges slow. If ever the phone thinks it is on USB, it will not allow more than 650mah to pass through the cable. So even if you had a 10amp charger, it would not use that much if it identified as a hub.
Using the cable I mentioned removes the ability for any charger to send the identifier info to the phone. Reason? You are missing the data+/- cables that data is transmitted through. Only the +/-5v wires remain.
Sent from my SCH-I535 using XDA Free mobile app
But why would the phone have a constant disconnection and reconnection while being plugged in? That's the part that confuses me.
Regardless, I just received my qi charge in the mail! It's been pretty nice so far! I'm happy to answer any questions about it if anyone is interested
Rushead, wanted to give you a heads-up about the latest CM11 build I used. I clean flashed 11-15 and everything was great except for the camera, which consistently gave me a "cannot connect to camera" error. Otherwise, it seemed like a great build with some great options. I gave up and clean flashed 01-15. Camera is all great except for the autofocus issue mentioned before. GPS lock is great, and battery life is loads better than my GNex days.
Regarding my qi chargers, I am pulling a net positive charge of 315mA on my house charger (Nexus 7 2.1amp AC adapter). This is with the phone turned on, connected to Wi-Fi, screen off, and doing nothing.
My car qi charger is doing about the same. I ran the GPS with screen on (auto brightness) and the charger only charged the phone 3% in 2 hours with screen on and GPS running the whole time. I might switch the DC socket to the included one to see if I get better results.
Has anyone had the problem of USB no longer working? It charges the device, but PC will not recognize the device - no icon or ability to see it as a drive in the PC. I've tried different cables and laptops, but same problem. (And the old cables & laptops work fine with my other USB devices). The phone & USB worked flawlessly the first 4 days I've had it - no problems transferring files from PC to phone & back.

Thanks for any guidance.
Check to make sure the drivers are on the computer and try a different USB ports

Make sure USB debugging is checked. Go to about phone. Go to "build". Tap on it rapidly until it says you now are a developer. Back out of about phone and go into the new option "Developer Options" and check USB debugging. When you hook up your phone you may get a popup that asks if you want to trust this computer. Say yes. On your notification page, it might say you are connected as an installer. Change it to media. Sometimes you need to toggle back and forth from camera and media.

Thank you. Yes, tried Dev mode and USB debugging, but no luck. Phone double-beeps when I connect the USB to it (and begins to charge), but no pop-ups on either phone or laptop in relation to storage / ability to manage files. No drive shown for the phone (whereas Thurs-Fri the phone showed up as an extra drive when I plugged it in.)
I also did a Factory Reset, just to see if going all the way back to square one would help. No luck there either. Phone still won't recognize laptop, laptop doesn't recognize phone.
That leads me to think something died in the hardware, firmware or something. This Win8.1 laptop works great with all my other devices.
I'm in the 10 day trial/return period (and coming from 2 yrs of flawless-except-****ty-camera HTC One M7 experience) - so if this is the "crap" quality people say is endemic to Samsung (srsly, 3 days and the phone does this? WTH), please let me know so I can get a G4 or Nexus 6 (can't go back to HTC M9 since the M7's camera was a 2 year prison sentence).

Been on the line with Verizon Tech Support for 2 hours as of this writing. Re-did all the diags, reset, Kies, etc. that I did Sunday from the VZN and Sammy websites. Combined with the re-setting of folders, Peel remote, TouchDown, etc. I'd done on the first phone, I'll have wasted a full day just fixing the phone.
Wish the HTC M9 had a better camera, G4 had better battery life or Nexus 6 had a better audio chip. If they send me a new GS6 and it flops again, does anyone have a recommended fallback phone to get as a placeholder until something better makes it to market (M9+ with fingerprint reader, better CPU, better camera)?

NO HELP FROM VERIZON "TECH SUPPORT" OR "WARRANTY" having spent 3 hours on tech support with Verizon...
Our Samsung GS6 failed Saturday (USB won't connect to any laptops using any cables) and I spent Sunday doing Verizon's online fixes (including safe mode, factory reset, Kies, etc.) and 3 hours with Verizon tech support this morning with no resolution.
Verizon is calling Samsung and "will get back with me later this week" if and when they find or make sense of other field failures that match my phone. (Really? And how would Zappos, Amazon and other customer service benchmarks handle it? Yep, overnight a new one after 5 min call and issue RMA for the defective item to be overnighted for tear-down / fault analysis). And by the way, my wife and I are paying for "next day" replacement and within the 14-day trial period...
So one would think Verizon would overnight ship a new GS6 out to me immediately and have me ship the defective GS6 to Samsung for tear-down analysis.
That's not the case. How Verizon is handling this frankly has us spooked that Verizon does not in fact stand behind either their products or "warranty" services.
I'd hope that our 14-day return-policy time-clock be reset and a new GS6 black 128GB be overnighted to me, or find some way of extending the return window (since the device, and its "warranty" and the customer "service" have all failed within 2 days of receiving the phone).
Think I'm going to be stuck with the LG G4 or maybe even swapping carriers.
Go to a store. If they can't do anything ask for a refund.

One of my laptops is personal Win 8.1, the other is corporate Win 7. Neither laptop recognized the Samsung GS6 after day 2, but worked flawlessly up until that time.
Still nothing back from Tech Support / Samsung "researching" the problem. Total WTF with those yaboes.
Monday I engaged the team who originally sold us the GS6 at our local store, and they're saying my new phone (replacement) will be in the store by Sat 6/27. 5+ days without a phone, but if this replacement doesn't suffer any issues, great.
Have you solved this issue? My wife's meet the same issue. And we did a lot ..... But it still no work.
This happened to me today. Computer would not recognize device. I toggled USB to camera mode then back to media device in phone settings and my pc recognized it again.
Hi, I bought a used Verizon Note Pro 12.2 SM-P905V and when I got it, noticed that the wifi is very flaky. Initially, it connected to my router fine but took 9 hours to load 120 apps when I signed in to Play using my normal Google account. So I did a factory reset, and then it wouldn't see my router at all. Restart router, factory reset device, no dice.
In the notification shade, wifi icon is always green as if it's on, but when I go into settings, the toggle is off. When I slide it to on, it turns gray and after a minute or so goes back to off. Multiple hard resets, still the same issue. Occasionally, it will "see" the routers, but this only lasts for a few seconds and then they are gone.
So I decided to flash the firmware. I did not complete another factory restore before I embarked on this, but had only just gone through the initial language screens and signed in on the tablet with a brand new Gmail account that had nothing on it. So I downloaded official 5.1.1 ROM from Sammobile, installed device drivers, installed Odin, (followed some great instructions found on XDA, thanks), got the tablet into download mode, connected to laptop and Odin on my laptop showed connection was live and it began to do it's thing. So I left it alone for 30 minutes and when I came back, Odin read "all done!" (or something similar) highlighted in green , and the tablet had restarted, so I assumed all is good.
However, I expected that the flash process would have wiped the setup I had begun on the tablet, but it did not. And the wifi issue still exists. Looks to me like nothing has changed. So two questions for you:
1) Does this mean that the flash did not happen correctly?
2) Do you have any suggestions on how I can fix this wifi issue? (LTE works fine but I don't want to eat up all that expensive data.)
Thanks for any help!
Wifi circuit has many components on mainboard and I believe it's beyond abilities of most users even professionals as you cannot find components and schematic to fix them.
Your best source is looking for this tablet with a broken LCD like this one:
http://www.ebay.com/itm/172145691764?_trksid=p2060353.m1438.l2649&ssPageName=STRK:MEBIDX:IT
http://www.ebay.com/itm/Samsung-Gal...069075?hash=item1a15927393:g:D8MAAOSwbYZXZKDb
If you don't have the need to LTE connection, Note Pro wifi mainboard SM-P900 also fit but you need rear camera for SM-P900 as rear camera of LTE won't work in Wif mainboard.
Any LTE Note Pro 12.2 like P907T( Tmobile) P907A ( AT&T ) mainboard will fit to P905V as they are exactly the same mainboard, except firmware, bootloader and software loaded into it.
I swapped a SM-P907A mainboard to a SM-P905V tablet, it works as an AT&T tablet because the software is for AT&T.
I purchased a verizon note pro 12.2 SM-P905V refurbished from groupon last October. For the last few months the wifi on the tablet has been very flaky. I have a number of devices and only this one frequently drops connection. I never upgraded from kitkat I and was hoping that this issue was software related. Seeing that moransw is experiencing the same problem with this same model but is trying to get back to sock kitkat gives me concern that a software update will not resolve the problem. The other problem I've been having lately is that the device no longer recognizes the stock charger, and will now only charge painfully slow. I've tried a different charge cable from a samsung s6 to no avail. Is the SM-P905V a lemon?
You should use this one to test your charger and usb cable
http://m.ebay.com/sch/i.html?_nkw=u....Xusb+voltage+current&sqp=usb+voltage+current
If you're using correct cable and charger, current should be 1.7 A and voltage should be 5.3 V
Test with known working cable and charger, if nothing is different you should consider to buy new usb flex charging port, around $10.
These basic steps you should do first as nobody can give exactly an answer with many unknowns. It happens to many used tablets, not just this model.
These basic troubleshootings are easy done for simple problem of bad cable, charger or USB port
Try them first then post your results if you need more help for further steps
