Software or Hardware problem ? And please, how to repair.

[Luko69]

hi guys,
i am an newcomer at this forum.
i need your help.
i have an problem with my mk808.
In the beginng, with the original fabrical SW run the MK 808 very fast, would say like" flash", performed many operation at a time /for example , in the backround I was downloading movie, in the foreground I was watching the another one, sometimes I was also net on-line..this all at a time/
In "ANTUTU" it has 9700 points.
Because there wasn`t possible to switch off this MK808 directly in SW, so I decided to upgraded it at altern. SW finless 1.7c.

At first, there was a problem with driver, but I instalated it , finally.
Then I made the upgrade to ..1.7c.
Was doing this exactly like in manual was written, didn`t become any system mistakes, the new system started to work.
I downloaded the "ANTUTU" as the first to see,if the MK808 works better like before.
Was dissapointed, because it was in lower quality like before... flickering in 2D test,3D screen fall down completely.
This I repeated more times.
allmost whole Test run in the backround(black screen)with result 5000-5600 points, sometimes it fall down total.
The power capacity of the MK 808 got down rapid.
I am not able to consider, if it is caused by GPU, CPU fault, or ..the all system has some defect. The actual situation, I have is, that it is no more possible to permormed many operation at a time..as in the beginnig was /downloading, watching movie, and be NET -online/.
sometimes, f.e. by "googling" I observed that the screen-colours were changing, it was violet, like in the situation when fall down the G component of RGB signal.
Could you, pls,help me in this case?..What occured here actually?
I am not sure, if it is caused by HW or SW, but I think, if the HW was damaged , it would fall down completely.
I opened this also to optical check all electr.contatcs, but all seem s to be OK.
Tried also „unbrick to fix NAND“..what I found in that forum as a possibility, but it didnt help.


Thanks a lot for your help.

Try to change your power supply.

Thanks leolas, I try another power supply with 2A, but no success.

Can you try to install stock firmware again and see if it works fine? Is strange, and it sugest a bad flash. I don't have a mk808, I have the b model, and I can assure you 1.7 for my device works better than stock one. The colors gambling issue suggest some problems with gpu or with hdmi wire. Do you use the stock kernel provided by Finless?

I think you might be trying t do to much antutu in particular the 3d one can wreak havoc on 808's don't use that as an end all be all of it working. Certain finless versions especially don't play nice. what it sounds like, especially if you get violet overlays has to do with GPU or the HDMI connection. if you experience it again try unplugging the HDMI and put it back, see if it fixes it. Don't open the case and try to stick a needle between the 8th pin Methinks either reflash of finless or switch to a different rom will clear it up, do me a favor and stay away from antutu tho, that can cause video issues (because it stresses your card clearly) if you absolutely HAVE to have some sort of bechmark score.. just disable vid tests. use software you plan to actually use as a benchmark, if it works fine PASS if it sucks, then start poking it with needles!

AW: Software or Hardware problem ? And please, how to repair.

Antutu is not the Score of all to Test it.
Try Epic Citadel from Play Store.

You can optimized the ROM for performance or Antutu.
What I will say don't trust it to much.

Many thanks to all for help. But, problem is not Antutu, it was an example. The whole system works slowly, now I go on "fabric" JB 4.2.2, but the initial speed is gone.

I ordered a new one MK808.
