*Updated* How to re-enable Tethering on KitKat. (New method on T-Mobile without root.)

Re: TIPS: How to re-enable Tethering on KitKat.

No such line exists in the factory image scripts.

It does exist as part of this guide which has 150K+ views: http://forums.androidcentral.com/ne...3923-guide-nexus-4-factory-image-restore.html (step 5).

Also, someguy01234 says that, in flashing, you "have to not type: fastboot erase userdata, which also delete alll your data". But the Guide says that the "first command is going to wipe all your old EVERYTHING from the device." The "first command" listed is "fastboot erase boot" while "fastboot erase userdata" is the last command listed. So, to save the data, do we not type "fastboot erase boot", "fastboot erase userdata", or both?

These three fastboot commands will wipe your data:
-If you unlock the bootloader for the first time, your data has to be wipe, you have no choice, which means anytime you type this and accept Yes on the phone: fastboot oem unlock
-When you flash an image, within the "flash-all.bat", there is the command: fastboot -w update img, the -w will wipe your data, you can remove the -w, to prevent wipe. However, there are times when your apps data have incompatibility with the new firmware image you just flashed and the phone stuck while booting, you would need to boot into recovery and wipe data. Stock recovery "factory reset" wipe everything including your internal storage, custom recovery leave internal storage alone.
-And lastly, fastboot erase userdata.

Notice that everytime you erase a partition, you need to reflash it or reformat it otherwise it doesn't exist anymore for the phone to recognize, which mean the phone might not boot successfully. So if you erase userdata, you need to either: fastboot flash userdata userdata.img (this is already included within the factory image), or "fastboot format userdata" to create a blank internal storage.

If you need to backup apps data before unlocking, use Helium and it's desktop companion app.

It is broken at the moment. But I cannot find any info for my phone specifically. But when I'm not busy I'll give it a shot.

@someguy01234 - Just so we are 100% clear, please confirm that "fastboot erase boot" does not erase the data, even though it is the first command on the Guide's list, and the Guide says the "first command is going to wipe all your old EVERYTHING from the device."

Thanks,

After some Googling I figured out how to edit the database file using command lines, this method will required some know how and is for more advance users, but if you are interested the instruction is in the first post.

No it wont. That command erase the kernel. All your apps data and stored data are in "userdata" partition.

it took me about 4 hours total to go from unlock > root to adding the tether_dun_required string. I bought the SQLite Editor for $3. A small sacrifice. Now my Nexus 4 can tether again after updating form Android 4.3 to 4.4

Re: TIPS: How to re-enable Tethering on KitKat.

I love the freedom that buying the N4 without a contract gave me. I just popped in my sim from my old Atrix and away i went. Now with this one PITA change in kitkat, i'm worried the carriers are putting a squeeze on google. So how many ATT + unlimited grandfathered data, people applied 4.4 and still were able to launch tether?

Does the N5 have these restrictions? I was thinking about buying one as an upgrade, but no way right now.

I am a grandfather at&t unlimited DATA customer and I able to Tether without issues on my N4 and N5 on 4.4.

Helium question: I decided to try rooting and started by installing Helium. When I went to backup, the only options presented were Backup to internal storage or Backup to cloud. There was no Backup to PC option, even though the Helium website says this is possible. I assume the rooting process erases internal storage, so the only viable option is cloud backup?

When you back up to internal storage it will save all your settings to the folder "carbon", just copy it to your computer (MTP sucks so wait and make sure all the files appears before copying). By default, carbon only save apps data, not the app apk, but you can swipe up from the main window and enable it.

You can also let Google back up your apps data by going to Setting -> Backup and reset enable backup, then sync your phone with "Apps data" enabled in the sync menu. I never tried it though, but it should work.

Great, thanks for the info. So after rooting just copy the carbon file back to the phone and it will be good to go?

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

Well copy it back, then launch Helium app, swipe left to open the restore menu. If you set Helium to backup APKs before then it will restore the app directly, otherwise it will ask you to download the app from the playstore first.

Hi
I have a lg l9 with 4.1.2 . I had also read on another website about using SQlite editor to change tether_dun_required to 0. I can do that easily but when I reboot and check it the value is back to 1. I do hit save before I reboot. Any suggestions? Also is there a way to tether with a usb cable to a Nexus 7? Would buying an old nexus 4 or a new nexus 5 straight from google help? Thanks!

 

[someguy01234]

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

This is for KitKat only running stock Android. Locked LG phones have their own settings that may prevent tethering. What you can try is head over to XDA and find a way to install custom recovery to it and install CyanogenMod rom.

Google do not sell the Nexus 4 anymore. You can order the N5, but you have to root it and redo these steps.

Thank you someguy01234. I used your easy method and all is good.

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

@nathan118 - That app is only for USB tethering. The 4.4 update did not affect my N4's native ability to tether via USB, so perhaps no app needed for that.

Would love to hear about an app that restores free wifi tethering! Installing an app would sure be much easier than rooting or flashing back to 4.3.

Is there any chance that 4.4.2 or any future update will restore free wifi tethering?

Good to know. Which carrier do you use? I have TMO, and losing tethering is the reason why I've stayed at 4.3. If you're tethering with USB on TMO, and others report the same thing, then I'll upgrade.

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

I am also using t-mobile. But why update? You would lose WiFi tethering.

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

Much thanks. I got hit with this exact problem when Nexus 4 got upgraded to Android 4.4 with Tmobile $30 plan unrooted. Recently (within last 4 days or so), Google pushed 4.4.2 OTA, and my hotspot has been working again (still unrooted). Not sure if that is going to stick with future updates...

Do you mean you lost Wi-Fi hotspot with 4.4.1 and got it back with 4.4.2?

Re: TIPS: How to re-enable Tethering on KitKat. *updated*

I didn't need to use the sql lite stuff like suggested and I don't have my phone rooted. Just do the following:

• adb shell
• put global settings tether_dun_required 0

Bam, no more popup!

I followed the Easy method and was able to fix the tethering for my laptop browsers, but I'm still not able to connect my PS3 like before.
