Need 720T Carrier folder contents

Hello, fellow 720T owner.

I just picked up 720T in decent shape off the bay. To properly activate it I need contents /carrier directory from 720T running preferably stock rooted ROM. If such person could copy contents of the directory using any root enabled file manager (I personally partial to ES File Explorer) and shared the contents, I (and probably other people) would be quite grateful. It should be quite small, under 40k, probably would have 4 small files and one sub-directory.

You have to use the file manager on the phone, not adb or anything on the PC.

I would appreciate anyone's help.

Thanks in advance.

WIFI FIX

Hello, after countless forevers trying to fix the wifi from the OTA NG5 update... i have successfully found a solution.

From your wifi-less NG5, you need to CF_AutoRoot. From there, Use triangle away and reset the counter. This will reset the binary and system status to official. Immediately following this step, reboot to download mode and flash your ng5 firmware in odin again.

whew.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] aprilx0x:
noob to samsung

Im being a total scardy cat with my new phone. I am familiar with the whole root process. I have had a Nexus5, MotoG, LG L9, HTC Rhyme, Tmobile MyTouch 3g, and with all them I have successfully rooted, flashed roms, custom recoveries, and unlocked the bootloaders on the ones I could. My son has a Samsung Stratosphere at one point and thats the only time I have played around with a Samsung phone. And that one I was never able to get rooted. So im a little cautious with attempting to do anything on my s4. I have the Sprint Galaxy s4 sph720t of course, and its the NG5 version/model whatever lol. Anyways.. I really want to root this phone. I cant stand all the preloaded apps and after 2 weeks its starting to seriously over heat and lag. So its about time.. Like I said I AM familiar with the whole process just not for Samsung. Any tips or anything that you can offer me? Anything I need to do BEFORE I attempt the root process? If somehow I mess this S4 up I will be without a phone for a good while since this is my 4th android this year. (I got kids and kids and N5 dont go well. They have cracked the screen on 2 different N5's)

The CF Auto-Root method looks to me that it will be the easiest for me to attempt considering my Noob status. Stupid question... Does this phone have bootloader that needs to be unlocked prior to rooting? I have googled it and havent come up with anything. Any and all help would be great!! :)

Team, I am becoming convinced that we do not have a working native tether solution. At least not a stable one.

Can some of you please try this and confirm your results? Also please confirm which native tether mod, you implemented.

1) implement a native tether mod (I used the telephony.db method).

2) turn native tether on

3) using another device (laptop, pad, etc), connect to the native hotpot

4) sit back for 5 minutes and watch your 720T to see if this message (see pic) pops up

5) please confirm your results in this thread (whether or not you got this error message, and what tether mod you used)

Thanks.

I have the native hotspot working fine on NG5. I got it working with both the telephony.db copy, and by manually editing the telephony.db myself.

You will get this error message when your phone loses data connectivity. Were you in a good coverage area, or was your signal weak? I have seen this message before, but it's only when I'm getting poor signal and I lose data connection on my phone. This makes sense as a wifi hotspot is useless without a data connection.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Thanks for the post and assistance. I'm in a high signal area. If you take a second look at the pic I posted you will see full bars in the signal graphic. Furthermore, tether router seems to work flawlessy in the same area strengthing the fact that the data signal is strong.

I have and like sqlite editor also, but if the telephony.db swap method (not galaxy tools) worked for you, then why is the moral of the story to get sqlite and do it your self?

I'm still trying to figure out why the telephony.db method is not stable for me. I wander if it has anything to do with me not setting the file permissions (that I've seen other people mention ocasionally) on the telephony.db file after making the swap.

Of course that is just a shot in the dark.

I only said do it yourself because I like the challenge and feeling of accomplishment of figuring things out for myself. I'm only trying to help others by relaying exactly what worked for me. I don't know if I mentioned it in my other posts, but my starting point for doing the telephony.db edit was after I did a profile update. That way I had a "clean", correct telephony.db from sprint. I then did the edits to the APNs in the telephony.db. Has worked perfectly since then. But it also worked perfectly when I copied over the telephony.db from the other thread. Here are screen shots of what my telephony.db looks like for the APNs needed for the hotspot to work - specifically the last 2 on the list. The first shows the names of the APNs, the second shows the edited values in mine that got me up and running. I am attaching the screenshots as well as my telephony.db file for anyone that wants to try it out. Of course I can't promise it will work for you, but it does for me. I'm running stock NG5 rooted with CF-AutoRoot.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Cooljb:
You're right I didn't notice your signal strength in the screen shot was good. It must be something else flaky with the configuration. I just posted a copy of my telephony.db file in another post on this thread along with screenshots of the edits I made to it. You can try either copying my telephony.db file to your phone to see if that works, or try to edit yours according to the screenshots I posted. All I can tell you is my native hotspot works flawlessly with the telephony.db I posted. I'm running stock NG5 rooted with CF-AutoRoot. Hope this helps. Good luck.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Your welcome. It has been beneficial for me too.

So far your telephony.db file is stable for me. I never thought about the update profile making changes to the telephony.db before. I can see that as a real possibility. I have run the update profile several times over the last few months. It may have changed my first modified telephony.db file and that may be when the problem started.

I will continue to study this and eventually update the op if needed.

Thanks again.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Cooljb:
I only thought about updating the profile when I was trying to get the native hotspot to work with galaxy tools. I emailed the developer and one of the things he mentioned is that when you update your profile it would wipe out the settings in the telephony.db file. So I experimented with it and in fact it did kill the hotspot when I updated my profile. I don't remember exactly which items it changed, but most importantly it took out the "dun" parameter. So it was a combination of looking at the telephony.db file that was posted in the other thread, the "clean" one created after doing a profile update and the modifications the galaxy tools app was trying to make to figure out how to manually edit the telephony.db. I decided a good starting point would be to have a fresh, clean telephony.db to start with.

So be aware that updating your profile WILL wipe out the hotspot modification to the telephony.db file. But even if you do update your profile, all you have to do is modify telephony.db with the hotspot parameters and you'll get native hotspot back.

On a different note and some time ago on a previous post, I said that I think wifi tether router will allow 10 connections and native will only allow 8. I want to correct that statement.

I think wifi tether router will only allow 8 same as native. The number 10 that I saw is in wanam. Wanam has a mod setting under "system" that will supposedly allow you to increase your limit of connections to 10. Whether it works on 720T native and/or wifi tether router, I don't know because I've never tried connecting more than 7 devices so far.

Supposedly, wanam will also allow you to reduce your limit to 1. This could be used to increase security by ensuring extra users cannot join your network if you want.

Knox flag and custom flag

Ok so if I am understanding, all the ng5 root methods trip at least the Knox flag correct? I understand that installing the custom recovery has alot to do with the trip, however I want to know if there is a flash counter associated with the Knox flag? If there is a flash counter at what flash count does it brick or is there no limit? By custom flag are u referring to the in os system menu status or something else?

I'm assuming that this Knox flag is occurring on more devices than this one, so has no one been able to reset it or has a method just not been developed for this model?
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:
Correct all ng5 root methods trip the knox. The knox flag is like a fuse. Once it's blown, it cannot be reset. The knox flag and custom flag are seperate flags. I have not messed with custom recoveries, but as I understand it, I don't THINK the custom flag is the same as the flash counter because the custom flag will trip on a non-recovery root method. The custom flag can be reset easily.

I don't know where the flash counter is. Hopefully, someone else will chime in and tell you. From what I've read, flash counters can also be reset.

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] bgmg:

[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Synderelle:
I Understand they are separate flags. My s2 epic 4g touch had the emmc flash counter built into odin, which was built by Samsung to alert them the phone had been flashed and after so many flashes the phone bricked by default. Using triangle away would fix that flash counter and set it to 0 as well as mark the system as official in Odin.

So I guess my question is for somebody who obtained root from a ng5 method, installed a custom recovery, and is using a custom rom.. I would like to know, when the phone is booted into Odin what it says exactly on the screen..

Ok, so I got the native tether data error again today using your telephony.db ...so I think it was more stable but not completely stable.

Next I'm going to try restoring my original telephony.db file, updating profile, then manually make the sql changes myself.

I am also starting to wander if NG5 may have a more stable native tether than NC6 does. I'm on NC6. It could be a intermittent bug they also fixed on the latest release.

I also use Mac address filtering with 7 mac addresses in the allowed list. Perhaps the mac filtering has some stability issues.
[Sprint Samsung Galaxy S 4 Q&A, Help & Troubleshoot] Synderelle:
So other than that nothing counts up right? On my s2 the counter would go up every time a rom was flashed and like I said if it wasn't reset to 0 it would eventually brick the phone. So I just wanna know if there is a flash counter or not.

Interesting. I didn't realize you weren't on NG5. Supposedly the same mod worked on NC6, but who knows. If you haven't already, you should consider updating to NG5.
