| Post subject: | Reballing BGA? |
This is most likely a stupid question, but since there's no manual anywhere, I have to ask: is it required to reball the BGA-chips prior using them in the adapters? (More specifically, the eMMC-adapters) I got hold of two scrapped Android-phones, both using eMMC, but nothing shows up when I connect them to the adapter hooked up to the SD-port. There is ofcourse a possibility I damaged the chips whilst removing them using the IR-station, but other than that I fail hard to understand why nothing happens with the adapters. |

No need. Use without reball. Just clean the chip very good. If you not clean enough it could be not recognized. Also there is a chance that you damage the chip. |

Thanks. I'm aware of that the chips could have been damaged, but I have to try everything I can before scrapping them. It's way harder than I thought to get dead devices to practice on. People are very very unwilling to donate their dead phones / pen drives etc, even if I assure them I only want to practise and learn on them. I wish I had a truckload of dead devices. These two phones are the first one I got hold of since november last year. Too long time between the cases = I forget everything I learned last time, and have to start all over again. And that sucks. |
