Tronsmart T428 Stock ROM - disccusions on the best ROM

[Guest]

I do not think it is a port from a 3066. The reason I say that is I have in fact flashed 3066 ROMs but using 3188 kernel to my new 3188 sticks. THEY ARE SLOW AS HELL!

So for sure the 4.2.2 is modified to support quad core. What exactly that means is beyond me at this time but I am sure it's not just a port but is recompiled to support quad cores.

Another thing. I can now mod just about any kernel to 1080 for 3066. But 3188 is totally different. I have yet to figure out how to patch a 3188 kernel to 1080P. It is in fact very different. When I decompile a 3188 kernel, how the structures are loaded is completely different!

don't use your t428 kernel, but use the 3.0.36 kernel of the mk808 or mk808b and system.img of mk808 or mk808b. i think this rom is the same of mk808 or mk808b but i'm not sure. (for sure inside have the same bloatware)

The T428 with 1920x1200 ui is very very very hot (risk of burn) and the performance are not good like the 720p ui (I have already tested)

OK I will try what your asking but I still think it is not the same ROM. But I will look into it.

The fact is that Rockchip has not yet developed rom 4.2.2 for this board.

The first 4.2.2 firmware from rockchip is only for one tablet and is very very joung. was developed a week ago.

I do not like to be teased by the seller (not geekbuying that is only a re-seller), so I want to investigate with your help.

I like the geekbuying service, is the only one that help users.

Thanks.

Well we have verified many parts of the fake 4.2.2 rom and now we can definitely say that it is a derivation of the old model rk3066 mk808.

We have verified the framework.jar with dex2jar and the code base is almost the same.
We have verified also many others native library and all are the same.

Rockchip has not yet developed a stock rom 4.2.2 for this board.

In the new Rockchip roms, also the settings are different. For example the old icon called "Screen" now have different name "HDMI" and different icon.

Watch on youtube the new rom made for many rk3188 tablets.

The only original stock rom for the T428 is the 4.1.1

Now, i don't understand, why BOB want make a custom rom based on an old rom made for rk3066 devices.

The fact that the customization of BOB don't work on 4.1.1 and work on fake 4.2.2, is another demonstration that the rom was born for rk3066 devices.

Bob, could you provide a valid explanation ? Please.

Do you want that we use a good rom optimized for this device, or you want only a rom in wich you can add your patch but ruine the Android experience on this device ?

I really don't understand what is your interest.

[Finless]

What the heck?

Are you attacking me in some way?

So I myself have done some poking at this. I am not sure who did your file analysis but this 4.2.2 is not just some mod of 4.1.1. Why do I say that?

First off let me say that this is Android 4.x.x is based of Android 4. Not something totally new like Android 5. So I would not expect framework or other files to be much different! Most of it IS the same! All Android 4.2.2 does over 4.1.1 is add features.

http://www.android.com/about/jelly-bean/

And in fact many of those features advertised in 4.2.2 are there! Just because rockchip did not make it, why does that matter? 4.2.2 has not changed much of driver and lib files so again, I would not expect much difference in these files.

Rockchip has not yet developed a stock rom 4.2.2 for this board.

May I ask where you have this information? Proof or just people talking on some forum?
Many RK tablets now have 4.2.2. So unless I see some statement from Rockchip that they have not made 4.2.2 for 3188, I wont fully agree with here-say comments.

In the new Rockchip roms, also the settings are different. For example the old icon called "Screen" now have different name "HDMI" and different icon.

This does not prove anything. I can change the settings label to anything I want it to say!
Now lets make sense of this!
A tablet has a screen and if it has a HDMI port then it makes sense to have the setting called HDMI. However on a TV stick, it does not since it is ONLY HDMI. So the ROM maker could easily call this "screen" since that makes more sense for a TV stick and a user. In my opinion this argument as proof just totally falls short!

Do you want that we use a good rom optimized for this device, or you want only a rom in wich you can add your patch but ruine the Android experience on this device ?

Optimized for this device... Hmmmm. The kernel does most of this work and as I said the system files then add to better performance. AND Hmmm lets see what did you say?

We have verified the framework.jar with dex2jar and the code base is almost the same.
We have verified also many others native library and all are the same.

If these files are all about the same, then why is it not optimized? If the 4.1.1 files are "the same" then how will that hurt 4.2.2 framework performance? Thus the only thing that can ruin performance of 4.2.2 is in fact the system framework NOT the native libraries or drivers since they are the same! So what you are saying to me does not make a lot of sense! think about it! AND if I used the libraries from the 4.1.1 ROM and use them on the 4.2.2 ROM, what's the difference then?

Now, i don't understand, why BOB want make a custom rom based on an old rom made for rk3066 devices.

Bob, could you provide a valid explanation ? Please.

Well, you can understand what you want! I disagree this is a old ROM and I will make a ROM from whatever base I want. If you don't like it.... DON'T use it!
What kind of pisses me off is you do not know WHAT I am making a ROM from AND in a post a few up I said I will make 2 ROMs! One from the stock 4.2.2 and one from the 4.1.1.
Some people want a ROM based on stock and some will want other things!
So is not it better to offer options and choices?


Sheesh man..... not sure why your coming here now jamming my ass trying to tell me what I need to be making ROMs from! Your argument is not logical or has any basis of fact behind it that you have proved to me. Go make your own ROM and let me decide what I want to do. Sheesh

The only tablet with 4.2.2 rom beta is the cube rk3188

Thanks for your reply.

[Finless]

Incorrect... Pipo has one in BETA as well.

Bob

[Guest]

Well we can have another real 4.2.2 rom from rockchip as base rom.

And not a rom that is for mk808.

Bob a suggestion for you, the rom of cube rk3188 work also on t428. Work on it for a good rom.

The ui is at 1920x1200 attention, your t428 became too hot.

The 1280x720 kernel of 4.1.1 rom have better performance.

Thanks for the info

[Finless]

Yes I have the cube ROM and am going to look at using it. I have to change much to fix things like screen rotation, etc.

But yes I plan to look at that as a ROM to base on.

Right now I am working on MK908 because it's ROM is REALY REALY BAD! So it needs help right now.
I put out my first T428 ROM for now but it is just a start., I plan to work more and more on it as I learn things.

Thanks,
Bob

For the moment, since the 4.1.1 rom is the most stable and faster, I leave some tips for customizations:

To hide the status bar, you can use the app full!screen

To block the screen rotation you can use the app Rotation Locker

For Xbmc you can use the last Xbmc 13 Gotham build http://mirrors.xbmc.org/nightlies/android/

Gameloft games work natively with no problem

If you want all apps in google play you can edit the build.prop in this mode:

ro.product.model = GT-I9300
ro.product.brand = samsung
ro.product.name = m0xx
ro.product.device = m0
ro.product.board = smdk4x12

[fwupow]

from Rockchip or not from Rockchip. 3D gone 2 poo.

So it yet remains to discover why 4.1.1 is so much faster. My understanding is that the new 28nm process allowed Rockchip to overclock the Quad Mali 400 GPUs, but are special kernel enhancements necessary to actually provide the overclocked clockspeed? If so, then it would makes sense that Rockchip would be the source for any such enhancements.

So the mystery of whether 4.2.2 is from Rockchip still plagues us. If it is, then what happened to the performance, especially the 3D graphics going from over 4000 down to 2500 in Antutu? I didn't buy the T428 w/ RK-3188 just to get the same 3D performance as RK-3066.

Well, anyhow, at least, we're off to a much better start than the GK802!

[Finless]

FYI, if you look at other devices where people have gone from 4.1.1 to 4.2.2 even on other processor platforms, the usual "theme" seems to be complaints of less performance. Just like when ICS first came out to replace GingerBread, the first releases of ICS were plagued with bugs and performance issues and complaints! Over time updates solved much of the early complaints. I suspect 4.2.2 will as well. AND if this 4.2.2 was not made from a generic Rockchip release, I am sure we will see one from Rochchip anyway.

FYI, looking at comments in the code of 4.2.2 and even in the kernel code for 36+, I see the same persons name in some of the new 4.2.2 code areas. So if that 4.1.1 was made by Rockchip I find it funny that the new code areas of 4.2.2 have the same user name comments as the rockchip 4.1.1! So I am not fully sure this is not from Rockchip as a base or "leaked beta" and then was modified Tronsmart or some software house they use.

Rom 4.2.2 of Cube U30GT2 from Rockchip on T428

the attachment is 1920x1200 because the kernel have a native resolution of 1920x1200

In this mode we can understand if sdk 17 is the problem for some apps or the problem is the old mk808 4.2.2 rom full of patch that ruined the Android experience

Only for app testing, because at this resolution the T428 is slower than the kernel 1280x720 of the good 4.1.1 rom


Who is tronsmart.com ?

Where is tronsmart in our discussion ?

[Finless]

The T428 is made by Tronsmart. Or at least advertised that it is. Do you have this stick?
Seems odd you would not know that.

the attachment is 1920x1200 because the kernel have a native resolution of 1920x1200

That is the screen resolution right? WHat is the HDMI output resolution? Seems many TV would not handle 1920x1200. 1080P is 1920x1080 not 1200.

The hdmi output resolution is the same of cube tablet 1920x1200 and this screenshot is taken from t428 with 4.2.2 rom of cube inside.

The tv scale this resolution to 1080p, but if you take a screenshot, the real resolution of the android ui is 1920x1200

Same kernel, boot , system, recovery, parameters, misc

Now in my opinion, the best solution is to integrate the kernel and modules of rom 4.1.1 to system image of this good 4.2.2 firmware.
