The change of heart leaves Huawei highly restricted. It's still on the Commerce Department's Entities List, preventing it doing business with US companies unless there's explicit government approval. Trump said the US would decide on removing Huawei from the list later, and noted that there was a meeting to discuss the subject on July 2nd.

The turnaround comes as part of a larger concession that could be good news for technology as a whole. The US is indefinitely postponing additional tariffs on Chinese goods in return for China buying large quantities of American farm products. This is far from a permanent solution, but it could reduce pressure on tech companies to move some production outside of China in their bid to avoid tariffs.

If Huawei does resume key US partnerships, it might come just in time to mitigate a crisis. Huawei has reportedly scaled back phone production knowing that its loss of official Android support and other partnerships would hurt its phone sales, and its PC business was in serious trouble without parts from American firms like Intel. Some of the damage is already done, but Huawei could leap back into the consumer space in key countries without resorting to alternate operating systems and less-than-ideal PC processors.
