It is frustrating when you can't install any paid apps for free using Tongbu. Unfortunately is it dead till now. No fix has been released to solve the problem. So I started to look for alternative for this. You may come across other similar apps such as VShare & Kuai Yong. I have tried all. It is somehow very difficult to get what we want. Even 25PP itself took some time for me to install apps without any problems and crash. But after a successful installation, I have no problems until now. I would say, it is much better and more stable than Tongbu. The only problem is, it is entirely on Chinese language. I tried to search for a simple guide to install PP25, but most of the time I end up in scam and just ads. There may be some other ways to install it. But this is what worked for me flawlessly. So be patient and just follow my steps very carefully. If you don't understand anything, please ask questions below. I will try to answer them as soon as possible.
