Hotspot mod native attempt (L720T) - Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot

I've been attempting to hack the on board hotspot. I'm referencing this thread.
http://forum.xda-developers.com/google-nexus-5/help/how-to-tether-blocking-fix-t2544487
I've made the changes to the db file, replaced it and it did activate. Just couldn't make a connection. I don't have great signal in my area at this moment, so I'm on assumption that it didn't because of that. Either way, I think I messed something up too because I had to hard reset after turning it off. There is also talk of changing your APN to IPv4 from 6. I didn't get that far. I think my error was with resetting the permissions. If anyone would like to attempt this with me, please post results. If anyone needs help I'll assist in what I know. This is for NC6 to be specific.

rooting will not kill your network connection. that's something that you did. you need to provide a LOT more information in order to have people help you out,
what ROM are you on, what settings did you change, what mobile carrier are you on, etc. etc. this is a simple fix, but we need to know what caused it first. :good:

Well the person above me said it. You just made a mountain out of a mole hill by giving out your imei to everyone on xda. Anyway, have you tried a factory reset? If that doesn't work take it to Best Buy and tell them Kies wrecked havoc on your device and they can re-flash your phone for free. Don't tell them it was your fault.

I don't know what the problem is but you should be able to flash the stock firmware in Odin and get your phone working again. Double check this in the i9500, i9505, i9505G S4 forum. You can get the stock firmware from sammobile.com

He should be able to flash it himself. The i9505 is not locked down like the i337. It's an international version so he probably can't take it to best buy, which is what I was responding to.

Data enabled, but no internet connection
Hello,
I have the stock rooted i337 (AT&T), running on another provider network. I am aware that i337 is very difficult to do modifications due to the built-in by AT&T vicious locks to prevent using it with other network providers. This is the reason I did not flash ROM, because I am afraid to get my phone bricked and lose it entirely. Recently I subscribed to a data plan from a third party provider and I have 4G in the status line and HSPA in the data type, but I still did not have internet connection when WiFi was disabled, except that my Hotmail somehow worked. No other apps requiring internet worked. I spent a week researching the issue myself as well as working with the provider's tech support, but nothing worked. Two days ago, almost out of despair, I installed a new app called Opera Max, which is developed to route the unencrypted data to their Virtual Private Network in order to compress it and save the data use. As soon as I connected to VPN, all applications started working. I still have to turn Opera Max off when I use WiFi, because it disconnects my WiFi every few minutes, claiming that WiFi signal is too low. (My signal is very strong and no other devices have any issues with WiFi). However, this is a minor problem, considering that Opera Max saved my data plan.
It is still a mystery to me why Hotmail worked, but no other apps and why using Opera Max VPN solved the problem. If anybody has ideas, I will be happy to hear.
I must say that all data settings, including APN are checked, rechecked and correct, so this was not the issue.
Thanks,
Dan
I am also having connection issues after rooting my S4 i9505:
I am on a Telcel (Mexico) which is supposed to support 4G connections... However, ever since I rooted I can only access 2G/GSM networks. I have the official APN network configuration and I have tried two roms but still no luck...
Any advice would be most welcome.

Sprint LG G2, no tethering option, bought from best buy.

Hi. I bought my phone through best buy and noticed I don't any of the sprint apps. Ive been trying to get the native hotspot to work but the option to turn it on isnt in the menu.
I'm rooted and tried the iceroom and stock versions of native hotspot. Also I've contacted another user who had the same issue, no hotspot option, also purchased via best buy.. Which is kinda odd. Does anyone else have this issue or know of a way of fixing it?
ya know, the same thing happened w/ me.......bought the phone from best buy and was looking for a hotspot feature and lo-and-behold, theres none to be found, even enabled dev settings and didn't pop up. I'm kinda dumbfounded and i really like the stock OS coming from the galaxy s4 and was hoping there was a hidden setting for it or if theres a rom that enables it because i'd be all over that lol

Extremely odd that it hasn't been mentioned by anyone else either. I cant even use any of the other tethering apps (wifi tether, barnacle, etc etc), I recieve ad-hoc errors, which I'm assuming is the issue with the native hotspot not appearing in the menu.
Still looking for a way to fix this if anyone knows how, would greatly appreciate it.

If you root and DL wireless tether you can't? Its a carrier option not an retailer option- makes no sense. Just trying to understand.. Contacting a friend now..

No. The phone is rooted and Ive tried the wireless tether app, pdanet, barnacle. Every wireless app shows an ad-hoc error in the log while pdanet gives me a htc sync error 2.
Thing is theres no hotspot option in the menu. Im sure its like that for everyone who bought the phone from best buy.

My question is: Why would a carrier do that? That is an upsell that they want to extend to every smartphone purchase, it's lost revenue. That is why I'm perplexed and have placed a call to my friend (MGR for VZW).
anyone figure this out yet? i have the same problem. bought my phone from best buy as well.

Apparently this issue is caused by not fully finishing the activation process for Sprint. Sprint base apps install after activation... my sneaking suspicion is they are installed via the "Sprint ID" app but Im not sure. Either try doing the activation again, or more likely to work is to do a full factory reset and make sure you do not interrupt the process all the way thru activation.
You will then have your tethering options back. Its likely the reps at bestbuy are bypassing that part of the activation process by interrupting it so they can finish your sale and get you outta there faster. Might also be unintentional on their part but who knows.
Do a factory reset.
noob question... will factory reset remove root and twrp? i have both, stock rom. i already backed up via twrp. however, will i need to install everything again afterwards?
You need to do a factory reset, no It will not loose root or twrp. As soon as you the phone boots back up, update prl and profile. Make sure you are in a good data location or are hooked up on WiFi. After updating both of these your phone should install all the Sprint apps and you will have tether option in settings

As bigpappa pointed out... it's not necessarily a best buy thing. It's the fact the rep probably didn't finish the activation process when setting your phone up in store. It could have been any store... it's just coincidence that the people with the problem happen to have bought from best buy.
lol i don't doubt that but i just had to give him hell because he was essentially trying to call us out who didn't have the tethering option and "debunk" it when it was just a simple statement that it wasn't there and was curious as to why, ive never really seen that happen before w/ an incomplete activation but its not like it really matters because theres tethering mods n **** out there that enable it anyway so just had to give him a little bit of hell haha
so... i factory reset my phone and it never went thru the activation process again. when i tried to activate device in settings, it said it was already activated. i quit and just installed the cm nightlies and now have wifi tether but im curious as what the fix could be.
After activation the Sprint Zone app runs and installs all the sprint bloatware and base apps. If you didnt have sprint zone load and start installing those apps, or quit that process manually then you didnt finish full activation. If Sprint Zone failed to load after the factory reset I dont know what to tell you other than to do it again.

i think that's part of the problem... there was so Sprint Zone app at all. i looked into downloading it but couldnt find anything.

Sorry, I muffed on the app name.... I meant "Sprint ID" app, not Sprint Zone.
Edit: check /system/app/ folder for sprintzone.apk, sprintid.apk, and sprintinstaller.apk. They may be there.

Neither were there when I went through my apps before... However, I already installed CM or I'd look. maybe someone else with the problem can take a look and test it out? Otherwise, I'm pretty happy with CM for the time being and takes me forever to switch as I'm still learning.

[Q] Lost LTE/4G

My very first post but a long time reader!
Somewhere along the way I lost LTE / 4G. It shows only 3G. Since I am almost always on WiFi, I just recently noticed it. I am on NI2 and 12.6 of OtimalROM. I am in a known 4G area as two other phones in my house are showing 4G - one is another S5. I have tried swapping SIM cards and it made no difference.
Under About / Status - it shows the following:
- Network: Verizon Wireless
- Mobile Network Type: eHRPD
- Service State: In Service
- Roaming: Not Roaming
- Mobile Network State: Connected
- MIN, PRL Version, ERI Version, IMEI, IMEISV, ICCID all have information in it.
When I type *#0011#, I get:
- No Service
- NETWORK: UNBLOCK
- IMEI Certi: PASS, 1
- Unknown
I have tried installing another ROM, ODIN an earlier version of the modem - without luck.
Any suggestions on how to get 4G back?
Not sure if this helps but I tried something I had not tried before. I went into ServiceMode (*#0011#) and then placed the phone in airplane mode and then turned it back on while watching what would happen. This is what I observed...
1. https://www.dropbox.com/s/xnikrs6lmnk1x0d/1.png?dl=0
2. https://www.dropbox.com/s/60c3qv7rtckqdx7/2.png?dl=0
3. https://www.dropbox.com/s/c57ibulvhl64g6l/3.png?dl=0
#1 occurs as soon as I turn off airplane mode
#2 occurs about a second before #3 appears
The other s5 in my home belongs to my spouse and is not rooted so I can't see what her ServiceMode settings are. I can see that her Mobile network type is LTE while mine says eHRPD.
Thanks again for any help.
I also have this problem, nice to see I'm not the only one. I was ready to think it was a hardware issue. I have tried all number of things. Have you at any point been on NK2? I'm on a Dev Edition S5, but stuck without LTE. Hoping someone can come up with a suggestion. My phone status reads the same as yours.
I'm hoping someone will have a fix as well. I have to think it is a setting in a config somewhere that got changed.
I'm on NI2. Have not tried NK2.
I was probing around in my build.prop file. I don't want to change anything in there because I really don't know what I am reading.
Is it possible that there is a setting in there that got changed?
I have looked to see if I can find a "stock" build.prop somewhere but no luck.
Can someone possibly provide me with their build.prop so I can compare my settings?
Thanks everyone.
how does one use that servicemode code? sorry I don't have anything to offer about your problem...
I typed that code into my dialer and nothing happened... actually dialing that number just gives me a message saying Verizon can't connect my call...
Open file /efs/carrier/HiddenMenu and modify its content from OFF to ON. Then reboot the phone.
I am on a Verizon s5 and I also lost LTE/4G. Also I cannot select any APN or mobile network. Any luck on your situation?

Sorry...I have not. I finally did a complete wipe of everything and took the phone back to stock - no safestrap, no root. I still had the problem. i don't know if there is a file on my SD card its pulling from. I have not taken the initiative to reformat my card. It's 128 GB and is half full. I don't want to even tackle that - as I really don't think that is the problem. I also don't think it is hardware though. Don't really know what else to do other than wipe the phone back to stock and replace it with another.
Well guys - I got 4G back!!!
Even though I'm still waiting for OptimalROM r13, I decided to install Extreme Syndicate OA8 in the meantime. I don't know why but it's back!!
I have imei cert pass 1 but still no service what now?

Wifi won't connect to open network. Connecting, then saved.

I tried searching this fourm, online, and no results after countless hours.
This is my problem. At work there is one big open network with a lot of extenders everywhere. When I got my new phone phone from BB when I broke my screen I tried to connect to it and it says " Connecting...." for a few seconds then automatically goes to "Saved".
I tried the obvious, forgetting network, rebooting phone, restoring to factory, updating firmware, nothing has worked so far. It always goes from connecting to saved. Every other device has worked flawlessly besides this phone
My last few phones have had no problem connecting. I do not have the authority to reboot the whole system, change frequently, add a pw, basically I'm only allowed to connect.
Wondering if anyone has experienced this problem, and might have any ideas or solutions. This is the only network that has ever gave me a problem.
Thanks for taking your time to read and help!

Axon 7 hotspot problems oreo b12 edition

ive seen a few people post on here with this problem but none of the posted solutions are working for me. Im on oreo b12, on verizon. i have tried rooted and unrooted. I have 4g lte data connected no problem, but when the hotspot goes up it is not transmitting data. I do pay for the hotspot which makes this aggravating. i did some searching on here and the xda forums, and i read about changing the APN settings, which i have to no avail in helping this. I read about the "settings put global tether_dun_required 0" and tried that only to get an error "failure calling service settings" (i may be a little off im running from memory right now). when googling that error i read about changing the selinux to permissive, thats where i was over my head and was denied, but i stopped there. does anyone here have an idea of another way for me to try to tackle this? was i doing something wrong? I was rooted when i tried all of this, i reinstalled and went unrooted to see if that would help but it did not. Any help or a guiding light would be appreciated and i know this question has come up a few times before its just not working for me.
I'm still on stock, non rooted Nougat and encrypted and have 2 SIMs, was hotspotting my personal SIM no problem but couldn't hotspot my work SIM which was a real PIA. I ensured the APN was good but that didn't help. After some googling for solutions I used my PC and ADB to alter a setting for it.
Now I can hotspot it perfectly. Can't remember what it was but it was a basic command. At the time I also removed a bunch of system apps I didn't use, mostly Google bloat. Made the phone snappier again too.

Keep your pants on, I never saw the reply here
If I get some googling time I'll have a look, but you guys could do the same...
Do it for all of us Google it for us before you post a incomplete reply. If you are unaware of how to create a link to save others to complete your reply maybe try posting that .
It's like saying I know where the true superior being resides in religious texts "Google It" as educated beings know there isn't one but that doesn't stop people googling it and leading them into a pointless search on truth based on someone's made up fairytale.
My pants are on the way they should be on unlike yours because I use a belt as where you has their bare arse hanging out for others to see.

Have a read of this and you get the idea of what needs doing. You have to be comfortable using ADB.

Another setting to try is:
net.tethering.noprovisioning=true
I can't check it myself as after Oreo update my phone works with hotspot off either SIM anyway.
