PP Jailbreak is another underrated team but i never had trust in Tiongs. And Tiongs don't trust their own
Lenovo PC and smartphones not only gives u bloatwares but malwares, spywares.
Also rooting tools by Tiongs, iRoot formerly VRoot, Kingoroot comes with malwares - the former exposed by Malwarebytes. Worse is it installs itself as system app making hard to unistall. Factory reset won't remove it. The only way to get rid of it is to flash it with customized ROM.
Towelroot and Framaroot also has been detected with Trojan but both can be uninstall after rooting and replacing with SuperSU.
Use Odin for rooting Samsung phones.
Use ADB (Android Debug Bridge) or Android SDK for other Android phones.
