Infineon i6 dual-core detailed line swipe brush the whole process! Finally solved the problem of upgrade failure

As we all know, before the Infinico i6 dual-core can not brush, this is a brick, there is no way. Afterwards, the short-circuit card swiping tutorial was dumped, but because it was difficult to short-circuit into recovery, the success rate was not high, causing the card brush to become a bottleneck.
Later began line brush research, Brush software found, drive installed, the computer also identified, but that is not to find a suitable drop line brush package, once went to other forums to find other flat drop package, replace, brush, later Failed.
Until later, Taobao finally came out with a line brush pack, and the jars were also shared by @Dai Long 100 million. They immediately evaluated it, but they stuck at 69% of the progress bar. Then they failed and became red. Someone evaluated, the evaluation was successful, and notices were issued, saying that all usbs were removed, including the mouse. But at the time, it was thought that only the wireless mouse should have no effect, and it would be re-flashed, or the card would be 69%. It didn't matter if it did not succeed, instead it drove the recovery completely. Can't pass the recovery card swipe, nor can it be upgraded by ota push. It has been in version 2.04 and cannot be upgraded.
I have posted several times and later found out that I was dropping one case. Enthusiastic dripping mode master stone so I take the initiative to add buckle, and analyze the problem with me, and finally to the stone engineer plus me, get a few times to engage in remote, but also replace the brush for recovery, or can not succeed ota. Finally, engineers could not find a reason. Thanks to the stone development team, the big gods are eager to solve the user's drop problem. Then read the post reply, said that without usb can line brush success, then change to remote control, mobile phone remote control computer operation brush, get rid of usb drop interference, and then miraculously brushed 69%, to 76% card for a small meeting Passed, green, and successful, the line brush tutorial is not detailed,
