[HW MOD] Replacing RK3188T with original RK3188

[serrj]

So after a lot of reading about limitations of T version I decided to try and replace it with original, non-T chip. I ordered one on aliexpress for ~$23. It comes already with soldering balls on it.

To perform this operation I used this magic tool


~80 sec. of heating and.. old CPU removed




Cleaning pads


surface is clean and ready fro new CPU


new with old RK3188


put some soldering paste (for BGA soldering)


And solder new CPU:



Result:

Well done on getting it to work, but why anybody would do this now with the T kernels unlocked I have no idea. It's not $23 worth of exta performance by a long shot, maybe $5.

Edit: Actually not even $5

I completely agree with you. I ordered this CPU when T model still was locked. So I made it just for fun
One small benefit - this one can be overclocked now up to 1920Mhz

The main thing is it worked for you, would of been a nightmare if it didn't and then was unlocked

That's an epic mod! Maybe a little over the top, but kudos!
