Hey heads up to you all... None... I mean NONE of the X1 prototypes work properly... NEVER BUY THEM... After sometime the power and voltage will really take a toll... The X1 was never meant to be that cramped for air and temp control... The K1 models strangely enough DO work without any power/heat issues. The X1 units have the speakers lose juice/crackle, and sometimes the game controller/system hardware will shut off randomly and need a hard reset. Bottom line... The X1 units were dreams and concepts... Never really developed on much. The older LOKI with the K1 chips must have had MUCH more debugging and designing done for it. The K1 unit I have has tons of apps meant to test/crash/force system performance problems and correct them.
*GOOGLEPLAY Store is not supported... This device is not known nor has any ID for the store. Just use another alternate STORE apk and sideload. The debug commands are nice and the ADB support is good on this. I just used the generic GOOGLE USB driver and it worked. You can tell that LOKI is not playing too nice though. I can send commands to the deivce and reboot it with the command ABD shell, it just loads no bootloader. It does not have one. Somehow there is a STOCK ROM on the recovery partition. Factory reset works and I have done it a few times.
Keep your eyes peeled for the K1 units... So please... DO NOT SEEK THE X1 models... Even if you find one that works to an extent... The design was NEVER perfected and the voltage and power draw is just too much and will eventually kill the hardware... The cracked tablets and Nintendo Switches PROVE they cannot handle the X1's temp and power needs. The Shield TV Box CAN because of design and fan design.
I also find that these prototypes are locked and not always usable. Devkit Keygen encryption etc. SO BEWARE...
I took a gamble for $170 and assumed that the later LOKI prototype with same 5" 720p LCD+ scaling chip / SAME as normal Tegra 4 portable would be way more developed... I was right. Seems that the only difference is the Android version and the SOC drivers for the K1 chip. One annoying thing I will say about the K1 protos is this... They are called LOKI Diagnostics in their model name and as such the device is not MADE for gaming rather for testing hardware and thermal limits. The SOC/CPU has 4 cores... Yet, 3 of them are LOCKED and turned OFF... I gained ROOT and got them firing up so it is possible to get them back! Just a FYI.
The only issue I have the with K1 model is the GPU drivers are older and the OpenGL support in the older Devkit ROM is not updated with optimizations. I hope to make my own ROM or get some help to modify the DUMPed ROM of the stock Devkit ROM. I also am surprised that the factory reset did not brick my unit... My K1 has no bootloader, it boots to a blank screen when using ADB bootloader reboot commands, so that is odd...
The K1 prototype I have never gets hot and the fan never kicks on. I did have it kick on when the 4 cores were running at full 2.3Ghz though. The fan did come on and once it hits the MAX 90C Temp/junction it shuts down. I do not think pushing it is good. Good luck finding one guys! Rooting was easy with Towelroot and SuperSU all works perfect.
THIS THING is the one one of the rarest things I have ever owned.
Nvidia Shield Portable Tegra K1 LOKI Prototype - Need help with updating the OpenGL ES 3.0 graphics source. Total NOOB.
UoYabuse runs way too slow and has glitches and such. I need newer OpenGL support for this Devkit Rom. Any ideas? I can dump the factory image and see about making my own ROM. I mean, I have the will but the skill will not be so easy... Heh.
The LOKI K1 prototypes are either busted with disabled CPU cores or bricked. The unit I have has a full factory ROM somewhere on the partition, somehow... The bootloader is gone... Only a black screen when using ADB for the bootloader command. So yeah, Very odd. I will say that it is great to have a working Prototype that has no crashes and power shutdown issues. I just want to update the ROM's graphics support and source to the recent K1's updates. Any ideas guys?
