confused sprint free tethering stock 2.1 gone 2.2

this is a short story of my past week saga.
a month ago i got 2 evos. wife and i.
i was sold on the fact that with these phones while one could pay 30 bucks a month for up to 8 on wifi hotspot,
OR!
they could be used for internet sharing over usb for free to one computer.
that is what 3 different sprint reps told me, and i was shocked b.c i thought there was no way to get that but i was clearly told and i asked repeated questions because it seemed like nirvana.
anyway i get the phones and as i am getting teh numbers set up do the dreaded late june OTA update which apears broke a bunch of your roots. bummer.
anyway.
i live in a 4g land and happily for a month on both phones I
turn the 4g radio on,
wait for connection,
connect supplied usb cable to computer with htc sync software installed
connect phone and use usb settings drop down to set the phone to
internet sharing over usb.
with in 30 seconds htc sync had added a network adapter and life was great.
i don't think i ever did it over 3g, however a sprint rep told me after asking "is this free tethering to one computer only on 4g thing?" replyied "i haven't had anyone say they couldn't over 3g but im not sure" but i tried once and i don't think it got working, i think i got error 67.
i thought it was hilarious b.c i assumed most were rooting for the great wifi teather, ?or usb? and it was working as so out of the box.
so after carefully reading the hundred or so posts by all rooting methods, what to do with adb, then the single click, then the single click removal due to messed up 4g stuff... i just kept waiting b.c although im sure i could follow a multistep nand root process, but as the phones worked so well as is, and i wasn't sure if teh 4g radio was sorted out yet in a simple root i just waited to root later.
so this past thursday or so i did on my phone the official over the air update to 2.2
3.26.651.6
and all day i was highly enjoying it. small changes here and there
UNTIL!!!
i went home and did the standard 4g radio on, usb connect, drop down,
hm... internet sharing has been changed to usb teathering....
and i did it, and nothing happened. error 67
so this time i unplugged radio 4g of on, confirmed in menu settings we were go with ip
and phone internet worked
but after plugging in usb and switching to usb teathering and quickly going back to the 4g menu status page i would watch the 4g radio disconnect, start scanning, maybe attempt to connect to sprint, then scann again forever
then dump a error 67.
so.... thats a frustration...
so i call sprint, and they say you need to go to a store to fix the update, yes they know it createdissues. so i go to a store.
they send me to another store, a tech store... they say oh you get error 67?
call sprint tech support they need to clear it up on their end.
so i call and they try it. i do the whole pound pount 32 somthing enter a code
off on
wait.
and still errors and no connecting...
so i call and they say you need to go back to the tech store adn have them put the update on.
i am slightly ticked at this point but totally staying cool.
i am starting to realize that this is an issue. and sprint has no idea.
next morning i do make it back to the store...
and speak with the tech guy
1st telling him the story.
2nd asking before anyother stuff, can we make this simple and restore my phone with thier tools to 2.1
he says basically, ah nope. i can't do anything. i have no tools.
i have no software. on this phone its basically the ota's htc send us.
so bascially spritn wants me to get all the way here,
and all he's going to do is go behind the door
punch around on my phone to make sure im not an idoit, then set the phoen back to factory settings, and make sure 2.2 looks aok.
so knowing this isn't going to solve anything, i let them go anyway so when i talk to sprint again i have followed their suggestions yet, i still have teh issue.
so that's what i do, and after putting contacts back on and using an app to restore most of installed apps. i head back home...
there is now frustration but still maintain my cool, bc after all i live in america, and i will get to eat today. overall life is good.
idea, lets call htc. so i do.
basically this person is slighly tech and proceeds to say,
from what i hear, due to a glitch 2.1 owners have free hotspot.
most likely that got fixed in 2.2
but i held my ground stating that hotspot and usb data sharing are two distinct thigns, and as much as sprint would like to merge and charge, that difference adn stated fact was the selling reason for me on these...
but she confirmed that there is no going back to 2.1
but also left me with a glimmer or hope.
so i called back sprint then sprint tech, then got on the phone waitng for advanced tech support to call me back on the idea that i just need my account provisioned for usb data tethering. which allows a 1 computer to share the data from my plan, and as i have unlimited, its no problem.
the tech tried to do something like that... but got to a point where we changed and confirmed something deep in my phone like either a 3g or 4g mac address was right, but i still had issues, and so he said he woudl have advanced tech call me back b.c they had better tools to assist me.
well that hour call back still hasnt happened and its around 36 hours know.
maybe i get a call monday..
however... at this point i am bugged b.c obviously there is still a 2% change this will get solved by the correct device provisioning,
however i believe now the sprint reps merely didn't know it was a glitch which allowed single person teathering so now if i call, basically all i get is big crocodile tears that say im sorry you were misinformed...
so the hilarious this is i still have the other phone, no way i will update that one, b/.c its our web lifeline now.
and if the other one gets sorted out great.
if not,
i have been waiting in the back, but this time.
im joining the others waiting for the FANTASTIC DEVS to find the exploit to allow nand rooting for the ota and stock shipped 2.2 evos
and i will be in.
it can't come soon enough.
thanks for reading, enjoy your night.
**newcomers like me to xda, please spent a couple hours reading up before you post or ask questions.
you will be shocked how many answers are here.

if all your wanting to do is tether to 1 pc through USB, than just get EasyTether.
It works great for me, and I still get 7mbs with 4g turned on while doing a speedtest on my PC. And, you do not need to be rooted to use it.

Yeah, thanks for the reminder, i tried that and pdanet first, but stopped bc i was able to with htc's stock software, and i was told its legit from sprint, but at this point it might be the way to get along till more headway is made, only 10 for the https and would work well as i dont need root. At this point 40 quarters is a better use of my time Still though kinda ticked at sprint, i feel like this has been a mega bait switch. They have been helpful, but they cant fix it.

2nd phone same problem.

Hey guys, I bought this phone for my wife about 3 weeks ago and we having severe issues with it. It seems that there is a problem with going from wifi to cellular signal. Sometimes the phone wont get a signal until it reboots and at times it dosent even do that. Also data has been non-existent except for the first days we had the phone. I don't think we could have gotten two defective phones with the same problem.
At first we thought it was the sim card, but we went to Tmobile and changed it out, also I used my sim from my Vibrant and did not work as well but her sim worked just fine on my phone. I am also noticing the wifi signal is very weak compared to my Vibrant. I though this phone was superior to my Vibrant hardware wise, but I'm starting to think otherwise.
Can anybody shed some light if you have had the same issues? My wife really loves the phone and she just wants it to work properly. What settings do you guys use under wireless and networks?

Have you tried factory reset? That will give you the original wireless settings that everyone else uses.

You're not using wifi calling are you?

Yes its a must that is one of the main reasons for getting the phone. We get no sevice in our house. Is app a problem?

Not usually, but i've noticed that it sometimes takes a while to connect to service after leaving a wifi area. Try and test it when your in an area with decent service and wifi.

T-Mobile LG G2 WiFi Problem

Just received my LG G2 White brand new from T-Mobile about 2 hours ago. After many attempts to troubleshoot the issue it all failed. The problem is Wifi will connect to router and even work but after 30 seconds the connection goes down. The actual Wifi signal shows connected but no internet it gets stock. We tried resetting the phone and toggling with different features but still it did the same thing. T-Mobile is the worst they were trying to have me ship the phone back and leave me phone less for days. I complained and they are sending another one overnight but have charged me for the phone on my account. Mind you I've had months of bad service, after all I think I got a defective phone. I've read some other people having the same issue with other carriers. If I get another one with the same issue I'm jumping boat. If anyone knows of a work around let me know. I tried 2 different routers same issues connects then it randomly disconnects and stops downloading or transferring data.
Reset Phone - didn't work
Turned off mobile data - didn't work
Turned off wifi sleep - didn't work

Is it an N router? You could try putting it in G mode just for better compatibility and see if that does anything.

Tried on G same thing, New device should work on N by the way seems like is a hardware issue

Try a public router like Starbucks or something

Just did worked for 2 minutes and again it stops. This is either a software glitch or hardware issue, very random

This is the big thing I miss on my Nexus. I was thinking if WiFi calling worked well on the G2 I may actually go back to a Tmo device.
Any reports of whether MMS is working with the WiFi calling?

u might have a defective g2. i have the tmobile version since thurday last week and never had an issue with wifi

Yes. Yes it is.
Sent from a phone

Well Ive found out that the phone is having issues connecting to 5ghz network or not updated routers. I think the phone is hella fast, camera is quite good but this phone doesn't live up too the hype. Specially if in my business were all gadgets, macs, pc's connect with no issue Im not going to reset router settings just cause this phone doesn't like it. Jumping ship, it was quite an awfall experience. by the way LG is clueless, dont even bother calling them..

I've had wifi issues like that on my Vz G2. 2.4 and 5ghz channels. None of my other devices have the issue. Forcing a new channel on the router resolves the issue for awhile, but it's like the radio is very sensitive to channel interference or something.

I have the same problem. It seems like it only works if you set your router to 802.11g only

My WiFi calling, SMS, MMS, and general WiFi connectivity on my T-Mobile G2 works fine. However the call quality over WiFi sucks.
What sucks is I really really like this phone. I'm conflicted on if I should return or keep. I go back and forth hourly.
Just for comparison sake I am using an Asus RT56N router and my G2 is connected to N network with Comcast but I frequently use G at a friends house using Century Link. It connects just fine on that POS network.
So I don't know what's going on here.

Well I just got a Galaxy S4 and I must admit the G2 has by far the better looking screen, camera and speed. I actually think Im going to send the S4 back and get the G2 again hoping that the one I got was just defective. Im so conflicted cause I really liked the G2 but the wifi issue is a deal breaker. Not sure what to do!

Maybe it was just a defective unit. I had to return my first one and I may have to return this one too. I keep noticing weird touch screen issues now. The first one didn't have touch issues but had speaker issues. This one looks like it may or may not have touch screen issues.
I took off the Zagg Screen protector to see if that was the cause. We will see.
My issues are a far less version of what's happening in this video.

I thought i had a defective phone.
Nothing worked even after router firmware upgrade
But at the end, it was because i had outdated router from 2005. Silly me lol
Bought a new router and now it works like a charm XD

I had same problem. I called TMobile and LG. But no solution. Then finally I found the reason. Just update your Router Firmware! Access your router setting thru the IP addess and update with latest firmware. Now my LG-G2 WIFI is working perfectly. My router is D Link DIR-655.

Problems with Tomato
Is anyone having issues with a non-dlink router? I have an Asus RT-N16 set up with Tomato firmware and have very similar issues as well. Everything on the internet suggests upgrading my dlink firmware... which obviously doesn't help me . Other people have suggested trying "G only" on the router, which sucks and is pretty heavy handed. Will report back if it works though...
Verizon version of the G2 VS98011A
Tomato Firmware v1.28.9054 MIPSR2-beta K26 USB vpn3.6

I have used my old NETGEAR wndr3300 (setup for 2.4 & 5Ghz) and my phone connected to either flawlessly. Then I purchased a DLink DIR-855 Xtreme and the problems started. Tried to update firmware, and the router would constantly reboot every few minutes when my G2 would connect to either frequency. Now I am using a WD MyNet 900, and no problems as of yet.

new g2 kills wifi
all of the symptoms mentioned are happening to me too but im on ee (UK version of T mobile). the network drops out on after a short time of network connection, i have spent 45 mins on Saturday talking to the (well not really talking more like listening to hold music) tech dept about internet connectivity problems and even convinced them that it was not the internet that was hiding but the router that was not performing so they sent me a new one; i eagerly swapped it over tonight and even factory reset the phone like lg have suggested but guess what...........
i have sent lg a snotty response as this issue has now cost me a bout 6 hours of my life trying to work wtf is going on and the on the phone to tech call centers and the inevitable net trawling for answers plus the effin and jeffin about after a complete factory reset.
it seams we are not unique in this and samsung have had this as an issue for quite a bit and best guesses are that it is a o/s issue with jelly bean 4.2 but this is not what google would have you believe and do not acknowledge this as an issue. im no expert just someone who wants the effing thing to work and have someone who has the power and capability to sort this out to do so without having to convince some faceless organisation that the problem should not be mine cos i dont get paid to sort out the crap.

Exclamation marks on WiFi and Phone signal

Every once in a while I go to use the phone and my WiFi and Phone signal will have exclamation points beside them. I have to disconnect and reconnect on the WiFi to fix the issue. Is anyone else having this issue?

I only see the exclamation point after boot or when I turn on WiFi: the antenna is in the process of connecting to the network / wireless router. Otherwise, I don't see the ! again.

I had it this morning. Turned off Wifi, and the cell exclamation point went away.

Same here. My phone was sitting beside me and had been getting calls and text messages all day long. I picked it up to look for something on Google Play and it would not connect. I was getting it on my cell signal but that was before I turned on Advanced calling. I was out of town for a conference and would see it while I was on the phone and email was trying to sync. Things that make you go hmmmm.

This happened to me tonight for about an hour. I tried everything but eventually it came back on it's own but only on 3g.

The exclamation point means that the WiFi or cellular signal aren't getting connectivity. The reason that turning signals on/off works is because you force them to reconnect.
You're getting these indicators because for some reason, your WiFi and cell signal are dropping out. If you were at a conference for a few days, then it makes sense you would see that on WiFi (since conference centers notoriously have horrible WiFi; especially when you have a few hundred people all trying to use the WiFi at once). If you saw it on your cell signal, then for whatever reason the cell connectivity dropped out for a moment.
This also happens on other phones. Have you ever tried to use internet connectivity on another phone, only to have it not work? You see full signal strength; you see the data indicator look like it's trying to push / receive data; but for whatever reason, you're not getting data for the moment. This isn't new to the Moto X Pure. It happens on other phones as well. The only difference is that the Moto X Pure tells you its happening.

Honestly, I really don't remember it happening on my previous phones. I'm not saying it did not happen but if it did it was not on a regular basis like here. My business is in my home. I have a wireless router downstairs and upstairs. It has already happened twice today.

I regularly get connection timeouts when browsing the play store, surfing the web, and using xda. On both WiFi and cellular data. I'm assuming its a software issue.

I believe that the cell bars with an exclamation point means that you have voice but no data connectivity. That's the way it has tested out for me over the years on various Android phones. So, you can make and receive calls, but not data.
I think, but am not sure, that the exclamation point with the WiFi icon means that the OS connected to the WiFi access point but not the Internet. That would indicate a handshake issue between the phone and the access point/router, maybe resulting in the phone not receiving an IP address or something. Though I've only seen this happen once or twice over many years, disconnecting and reconnecting the WiFi (turning it off then on on the phone) usually clears the problem.

Just sent mine back as my signal issues really hindered use of phone. Was hoping for ROM before return deadline to see if it would fix it. But that has been slower than I thought. Tried everything in the book to fix this issue. Doesn't matter if I'm in excellent coverage or not. Screen off phone goes 1x then screen on stays until I play around with settings or hidden menu. This is on Verizon. Tried new sims. Wonder if Verizon is doing something to limit these unlocked phones.

That was a given. New nano sim not trimmed down micro. At first I had trimmed my g2 micro sim which I thought was reason for issues at first. I have a friend at local Verizon store who is more knowledgeable than usual CS agents. Still couldn't get anything to stick. Hidden menu setting for network always switches back to lte ,gsm CDMA auto prl. Phone was purchased through amazon. Hope its just hardware related. Gonna go to best buy and pick one up there. Easier to deal with them.

Liked the phone so much. I decided to reorder. Will have today. Here's to hoping it fixes my issue. Lots of signal issues with the custom ROMs right now. Especially Verizon users. Hope it gets ironed out soon. This really makes me think Verizon is doing something even though its not a carrier phone.

It's not necessarily a phone issue. My wife's Moto X 2013 and my Moto X 2015 had this come up on both phones at the same time, exclamation mark by both wifi and lte signal icons. Rebooting phone didn't help. Calling still worked, data did not. I went in and rebooted my router, and the exclamation marks went away on both phones.

I gotta try that.My fiance's X 2013 always gets it in the apartment.Maybe I should try to get her a new sim as well?

I had this happen to me today. I had installed an app that was burning through my cell data, used 90% and I have two weeks left on my billing cycle. I turned of cell data because even with just routine phone useage I did not see the 10% lasting. However after doing this I could not connect to wifi. I have full strength signal and it says it is connected but there is an exclamation mark by the wifi meter and nothing will connect to the internet. I turned cell data back on, and it connects, but wifi will not. I found that by running my vpn it connects and now I get data via wifi through the vpn. If I shut the vpn off, no more wifi data. WTF??? I've researched and this seems to be a lollipop issue on several different phones. I've tried every solution I could, (except for those that require root). Has no one found a solution for this? Motorola?

Note 4 no longer supported by T-Mobile No Network

My husband and I both have a stock N910T. When we woke up yesterday neither phone would get signal, and not even make wifi call. Went to TMo shop today they told me that they were no longer sending signal to Note 4's (Thanks for the heads up TMo). We really like these phones and I wonder if I could root them and flash a stable ROM and get service on them again. When I pull the sim it shows 5 bars, put the sim back and X. I have rooted many phones, but not since I got this one 6 years ago, so I'm sure I'm a bit rusty.
Any advice highly appreciated. TIA

I'm in the same boat with the note edge. It stopped working friday night for me. Put the sim in a stock note 4 and same thing, so I thought my sim card died. Went to the tmobile store on saturday and they said 2 people had came in with the same issue and they had note 4s.
What I don't understand is how they can just stop supporting a phone. I thought that if it accepts the sim card and has the proper bands it'll work. I mean for ****s sake my car takes a tmobile sim for a hotspot and traffic updates.

same exact. i just factory reset and updated stock to see if it would fix but it wont. Any solutions here??

Try to:
a. flash a custom TWRP (recovery) with Odin
IMPORTANT - after you flash TWRP PLEASE TAKE A FULL BACK-UP!
b. flash a custom ROM with root
c. why root? because you can change the build.prop file and "pretend" to be another phone (newer more likely) so that the lovely t-mobile can still allow your phone to connect to the network.
This way you have zero costs, you keep your note 4.
Unless it's too complicated or the procrastination level is TDH (too damn high)
Or you have the cash and buy something new(er).
There's info on this forum about all these steps.
Before you do anything - go and read, search on this forums and on youtube. There are a LOT of tutorials.
Please be careful and READ. Get educated about custom recovery/ROM's.
You will get good knowledge and your satisfaction on make things work will be enormous.
You will be responsible on your actions with the phone.
Good luck.

mine is already rooted with a custom rom. which parameters do you recommend changing in build.prop?
my audi is older than the note 4 and data works fine and calls work on a motorola L6 from 2005, so I doubt it's the age.

someone on reddit came up with a temporary solution until they fix this. you'll lose 4g/LTE tho
To set to 3G/2G turn on airplane mode and enter *#2263#* on the phone dialer. Then select GSM/WCDMA Auto. After that turn airplane mode off.

Hey all - same issue here - Note 4 stopped working Friday morning. I tried everything on my end (factory reset, ROM flash, SIM swap, etc). I even tore the phone down and checked the connections. I ordered a replacement SIM / SD card tray reader thinking that was the issue. Now I hear others having the same issue. I live in Colorado FWIW. Calling into T-Mobile now to see if I can get some info here.
---------- Post added at 02:50 PM ---------- Previous post was at 02:31 PM ----------
After speaking on the phone with a tech support person, T-Mobile reported that they were aware of an issue with Note 4 users not being able to access the network. They said that they "were in contact with Samsung and were actively working on an issue" and reassured me that they would have a solution for customers soon. I sure hope so because I do not want to give up my Note 4!

Note 4 user here too. This sucks. I did the workaround on the dialer posted in one of the above posts, and now it connects. Says 4G at the top, but probably only 3G. That's fine for me in the meantime, but not acceptable in the long run. I just spent 2 days wiping the phone, unrooting, etc only to find this now! Got lots of work to do to get it back to my rooted state. Thankfully I have the backups to do it, just have to find the time now. Thanks T-Mobile!!

Has anyone heard any more on this issue?

Just had the same issue. Called T-mobile support and they had no idea of a widespread issue, said it was likely HW failure. I got a new SIM and that didn't help. Called local cellphone repair shop and they indicated they'd had several calls about this issue and fixed at least one so far by replacing the card reader. I applied the workaround above and got the phone working again so I don't understand why a new card reader is going to fix this.

Note 4 seems like it's back working on T-Mobile as of last night.

HI I purchased galaxy note 4 3 years ago in the first time I put him on i has that problem yet
But I live in curacao in the Caribbean and I think that the mother board was not good.
Then I has flight to medellin Colombia with the phone he began working I was glad but when I arrived to curacao from medellin the same problem
Sometimes he is working sometime not
I have the same problem T-mobile N910T

Thanks for the update! I reversed the workaround I applied earlier and mine is back to 4G LTE now.

Any update on this issue?
The N915-T is spotty and I'm trying to figure out why. It was officially kicked off the network by T-Mobile, but it still works. It connects to most towers but not to a particular one. Whenever I'm on that block the network can not be found. If I walk two blocks away it would connect to another tower and I can make calls. If I walk back toward the 'faulty' tower while on the call, the quality would degrade, the call drops and the phone would lose signal.
This would NOT happen with other phones - not even an older Galaxy S2.
This is likely a different issue altogether, as the phone actually connects and works elsewhere. I'm just hoping someone has an idea.
