My phone is a Sprint-branded ZTE Flash N9500 but purchased through Kroger iwireless, an MVNO of Sprint. I *think* what I used was one of Bin4ry's apps or shell scripts or something. I had been having issues with cell signal all day today so I was troubleshooting the phone and did a factory reset which of course un-rooted the phone.
The major issue I am having with finding a workable root guide is that I use Mac OS X, not Windows or Linux. I downloaded Root_With_Recovery_by_Bin4ry_v33 but it is not going as planned. I think what I used last time was v32 or v36 but I downloaded the linked file via the forum post here in XDA-Dev's but the file is corrupt or something. It is a never-ending cycle of zip and cpgz that just I can't do anything with. I thought that was the one, but perhaps OS X Mavericks isn't able to natively decompress the file whereas Yosemite beta could.
Info about my phone:
Baseband version: N9500B01
Kernel version: 3.0.8-perf-svn22621
SW Version: N9500V1.0.0B18
HW Version: c7zA
If you could point me in the right direction to be able to re-download the correct (or A correct) root guide for this phone along with files that will work, I would greatly appreciate it.
