I sent my phone to HTC and they replaced the motherboard. The whole cost was still cheaper than buying a new phone, so I went that route.
Since they get the replacements from their available stock, I had not much control on what they were using. So guess what...Samsung eMMC chip again.
1-Is this chip really that bad and I'm condemned?
2-Rooting my phone would give me any options if the same problems happens in a future?
a) I have the old motherboard
b) a Sandisk eMMC chip does cost about 10 bucks
c) I know someone with the right tools to replace this chip.
If the same problem happens in a future and I replace the chip myself, should this work immediately of should I have to "prepare" this chip with some special software?
Thanks for all the support given with my issue.
