HPH RK3288 ROM v1.2 by mo123 (20141117)

[mo123]

Hello I flashed the HPH_RK3288_ROM_v1.2_mo123 to a RKM 902II. It boots fine and I see apps but when it starts up it say to click to enable wifi. However not networks show up. Is there something else I need to do. This is my first attempt...noob.

You need to flash your stock kernel.img & resource.img with this ROM since Rikomagic RKM 902II uses a different wifi chipset and configuration.
Use the second tab of the flash tool to unpack your kernel & resource.img from your stock ROM.
If wifi is not working you might need to flash your boot.img also.

Hotspot bug : resolve !!!

I finaly found how to solve my problem, I just delete all the folder /data/misc and it works ! No more reboot, I think that the initial configuration was wrong.

Can use Catlog app from the Play Store to log all actions/services operating on your device.

I install the app and the last line before it reboot are :

Thank a lot for your reply, I check the heat, but it's very not cold, i'm not sure that the Wi-Fi chipset is overheating. Is there a file where the system errors are logged, to check the cause of the reboot ?

Maybe the Wi-Fi chipset is overheating? You could try using a small piece of thermal tape (they come in little squares or in a big sheet that can be cut to fit) or thermal paste and either a small heatsink or a copper shim. I had this problem with a linksys wrt160n, and ordered the thermal pads bc I saw some others fixed theirs with thermal pad(tape) and copper shims but never got around to fixing it. I was just restarting it every few days when it overheated. I ended up replacing it recently with a linksys e1500 that I got for free from a client when I replaced the e1500 with something more heavy duty. I put dd-wrt on the e1500 and haven't had to restart it a single time since. It's extremely stable and been running now for weeks. I'm not using dd-wrt to increase the signal output above norma because I already get good reception at stock output throughout the house.

Check out this http://toomanycomputers.blogspot.com...ution.html?m=1

You can get the thermal pads and copper shims very cheap on **** if you don't mind waiting on shipping from China (could be a couple of weeks up to a month or possibly more depends where you live). If you order domestically you can expect faster shipping but cost will probably be a little bit more.

Could also be a software issue, but possibly worth trying this. I don't know which system you are using, but if you crack it open, I'd check under the heatsink of the cpu as well and if it has a thermal pad it's probably a good idea to replace it with thermal paste because the paste will transfer heat to the heatsink much better than the pa. It's very cheap and readily available on **** and lots of other places, too. Even local computer/electronics store should have it(though **** is likely cheapest. I use this a lot so I usually order about 6 syringes of it at a time. I don't see much difference in cooling if I check temps between the cheap stuff and more expensive brand names like arctic silver). Thermal paste conducts heat much better than the pads, but is probably fine for Wi-Fi chipset. Especially since it's sticky and you need to stick something to it to dissipate heat(thermal paste is not sticky). There is a thermal epoxy which is permanent. I have not tried the epoxy, though, so I can't say how well it works. Hope this helps!

Odd, Ugoos is telling me different, that because of the "HDMI Switch" used it limits the output to 4K@30Hz, HPH_Tina said the same thing in a thread i read here about there box with the same PCB

Maybe different people with 4K TV's can test it and report back.
Only way to know for sure.
I know new firmware added 4K 60Hz support which wasn't present in earlier firmware.

Why such an old busybox? Safe to update?

Thanks!
-SB

All the RK3288 stock ROM's come with that busybox.
Can include a new one, but will have no effect for 99.99% of people.

[mo123]

@mo123 Can I just use the android tool 2.3 under download image to flash your boot.img on top of the existing tronsmart boot.img on the device or do I have to go through the whole process of using mkupdate.bat and flashing a single image again?

Yours is 44KB larger than the stock one, but I used your parameter file when I made the image before so it shouldn't overwrite any partitions or anything, correct? How about wiping the partition first? Is that automatic?

Off topic but has anyone found an accurate way to monitor the temperature on these?

Thanks!
-SB

Yes, better to flash individual images.

[mo123]

So, Yes or No, is 4k@60Hz possible on my UT3 4/32GB w/ fan?

Yes, 4k@60Hz
You will need to use a compatible HDMI v2.0 cable and use a compatible 4K TV.
Unfortunately not all TV's display all the resolutions.
The HDMI-IN port only works at 1080p@30Hz.

Oh I just reread your post and saw you are using tronsmart r28. I dunno if they are using the thermal pads on the CPU as the r89's are or not but if I had it open I would certainly check.

Cheers,
-SB

According to this http://www.cnx-software.com/2014/09/...-r28-unboxing/
There is thermal paste and not a pad, which is a good thing. Although this is a beta model, but surely they kept this in the production run.

I guess if you pop the top you can let us know.

Yes the HPH also has an HDMI-In and uses the same board as the first Ugoos UT3 without a fan.
To use the 2nd version of Ugoos UT3 with a fan, you will need to find the driver/name to make the fan fully compatible with a custom kernel. Maybe open the device and post the make of the fan if possible or ask Ugoos.

So, Yes or No, is 4k@60Hz possible on my UT3 4/32GB w/ fan?
