Yes, similar things happened for the TowelRoot on the S5 too.

Here is the Verizon Samsung Galaxy S 4 General [HOW TO] [ROOT] [APK] Root for NC5 OTA (All Kitkat devices) without PC!!! thread.

It also refers to TowelRoot app, which only works on older firmware versions ... unfortunately no longer on latest versions. (As they have the respective exploit patched.)

And the Verzion S4 has a locked bootloader. That's why you can't flash a custom recovery etc. with Odin.

A possibe solution coud be to "downgrade" to an older firmware (or kernel) and then root it with TowelRoot.

EDIT: I see that you have already asked in the Verizon Samsung Galaxy S 4 Q&A, Help & Troubleshooting forum.

That's the right place. Be patient and wait for a better advice from there.

MALI GPU VOLTAGE CONTROL

OP's,

Have you had any luck getting sysnapse controls to work with [MENTION=4167023]AndreiLux[/MENTION] patch for Mali Voltage Control ?

For my N915S SkyHigh kernel:

I've implemented GPU synapse controls as displayed in screenshot, but changes immediately revert to stock values upon "apply".

No problems with the devfreq synapse contol implementation though, all working as it should (so far).

Just wondering if it's just my GPU synapse implementation or AndreiLux's patch/s ?

I did check the permission are 0644 for volt_table. Also, I check with DVFS disable/enabled with wanam DVFS xposed app.

Synapse boot canceled

I am facing "Synapse boot canceled" message at the very first 5 seconds after rebooting. and it always show that "Synapse granted SU permission" , I mean just after that "canceled" error shows.

When opening synapse after the reboot, It always says "the last applied settings have not been deemed stable due to a possible crash or reboot of the device, settings are deemed stable 2 minutes after they're applied at boot. press cancel to reset to the last savd settings".

I think It is something related to SuperSU, especially after update, It was working fine before updating SuperSU.

Kernel is v.9 (I had the same issue with .7 already), my device is 910C for sure, and rooted, with Dr. Ketan V2 ROM.

Is this error affecting the kernel modification settings, any known solution for this???
