I decided after some back and forth to keep my Sprint EVO 4g LTE a while longer. Compared with the new Android phones out there I didn't see much benefit that updating the SD card and installing a custom ROM couldn't solve. And besides I didn't want to get into another 2yr commitment with Sprint, let along pay hundreds for a new phone. I figured too with rooting my wife’s LG LS720 how hard could be? Well after some time last night and several hours today I'm stumped!
I initially tried rooting via the command prompt and Flashboot method about year ago and ran into problems and so put it aside and told myself "I'll wait until some better instructions or guide come out and give it another shot." Well this time I stumbled across the WinDroid Univ Android Toolkit and figure I'd give a try.
Despite some initial hiccups on my part, I was able to get to the point of unlocking my bootloader, installing TWRP 2.8.30 recovery, and obtaining what I thought was my SU root. While in TWRP and hitting reboot, system and choosing to install SU and rebooting, I get the following error in red letters: "E: Failed to get default context and file mode for storage files.", followed by MTP enabled and then saying it is loading the SU script.
Once booted up and going into Apps, I found no SU app. So I tried the install process once again and obtained the same results. I even went to Google Playstore and downloaded SuperSU and installed it and then received the following error message: "There is no SU binary installed, and SuperSU cannot install it. This is a problem." However in TWRP file explorer I see that the SU directory is created and what "appears" to be all the appropriate directories, files and the apk listed.
I did a google search re the red lettered message in TWRP and came across a thread at the Android Stack Exch and found that another TWRP user reverted back to 2.8.0.1 and found that the error message went away. Would this error message be tripping me up? Should I revert to an early Windroid toolkit version and if so which one? I tried too, installing the SuperSU 1.94 zip file via TWRP and had no luck there either. I do have S-ON. Do I need to be S-OFF? Finally, I do have a SanDisk UltraPlus 32GB micro SD HCI card installed. Should I remove the card?
As for specs the following are of my phone:
HTC Sence 4.5.,
EVO 4.1.1.
Jewel PVT SHIP S-ON RL
SW Ver: 3.17.651.97IORD
HBOOT 2.09
Radio: 1.31.11.0830
Open DSP: 131.11.0.45.0815
eMMC-boot
I have Windows 8.1 desktop and Windows 7.0 laptop. I started out using the desktop a Sony Vaio A-n-1 but was having USB connection issues so switched to using my laptop.
Thank you in advance for your time and any helpful instruction you can provide.
