That's the parameter file you flash. Try the variable par file.

tried using the variable parameter file from the lollipop 1.2 5.0. Can anyone verify if the android bootlogo should appear for longer time before going to the cyanogenmod logo? The parameter file contains the size of the internal sd card, and i thought the former parameter file (variable size) would also work with the new lollipop cyanogenmod 12.1.

things that don't work yet:

- visible camera turned to the right

- size internal sd card 16 gb instead of 32 gb, guess we need a new parameter file

- auto rotation of screen doesn't work

So, in order to conclude.

Up to now we have an almost working ROM from OMA on U30GT2 with the below non working list from Mark06

 

things that don't work yet:

- visible camera turned to the right

- size internal sd card 16 gb instead of 32 gb, guess we need a new parameter file

- auto rotation of screen doesn't work

 

Shall we create an installation guide? So I can edit the 1st post at the front page? Mark06 what's your opinion?

PS: Thank's all for your support at this "old tablet"

You can do that, just think the kitkat 4.4.2 from kasty is a little snappier. Had this rom working at antutu 26900, i guess with the 38 kernel, but i can't get back to that score. Highest i can get now is about 22000. Maybe we need to first get that high antutu score back and know how to do that, then maybe it's even better than kasty rom last year. Then make a manual.

Totally agree, if the general feeling of the ROM is lower performance than the Kasty 4.4.2 (20140606 funromstudio) we need to wait for something at least with the same stability.

@stathis1985: it is very stable now, the cyanogenmod 12.1 for cube u30gt2. Just it's a bit frustrating sometimes waiting for an app to open. Maybe the performance can be tweaked. Normally i just overclock it with : cpu1800,gpu798,mem720, but then it's even lower than the normal non overclocked kernel. This hasn't happened to me before with the other roms. Would almost say, overclocking at that clockspeed is downgrading the performance. Maybe take a little step back, so cpu1800,gpu768,mem720, will do the trick. It's just not stable at the overclock to the max speed like the kasty rom f.i. is.

 

*edit: there is also a newer androidtool v2.3

*edit2: format with androidtool and kernel overclocked 38 gives antutu 22000. Had antutu @26900 with kitkat 4.4.2. But when the social apps you have installed are in memory, you can work very fast with the tab. It's a 2 gb tab, so if memory is used well, the user experience is very good with the cyanogenmod 12.1.

 

*edit3: used 'root app remover' to deinstall the bloatware (also phone stuff) and apps are very handable. Facebook is also very well showing the movies in the posts. Parameter file for 29 gb is working well. 

 

Manual:

Download newer androidtool, cyanogenmod 12.1 rom.

Unzip all.

Install drivers for usb connection u30gt2(see the unzipped cyanogenmod 12.1).

-turn tab off
-hold down volume up and power button
-when you hear a click/tab is turning on release power button, keep holding volume up button and insert the usb cable to pc
-after 2 seconds also release volume up button
-now windows should find the tab(bootloader mode) and you can (start flashing) continu.

Startup androidtool, do an idb erase/lower format.

Then select:

/CrewRKTablets_Odys_Iron_CM12_LP_5.0.2_v1.0
ockdev\Image:
- boot.img
- misc.img
- recovery.img
- system.img

/CrewRKTablets_Odys_Iron_CM12_LP_5.0.2_v1.0
ockdev:
- rk3188(L)_V1.24.bin (loader file)

parameter file: androidtool parameter file.

kernel.img

Mark all the loaded files for the flashing.

Start flashing.

At the end of the flashing the tab wil reboot into clockwork menu. Now do a factory reset. Next reboot the tab(select two times no (fix su and fix recovery menu))

Now wait some time and you're in android lollipop on your cube u30gt2!

 

thx to shokk2(parameter file), Oma7144(cyanogenmod for cube u30gt2).

Simply awesome. Now you did not mention in manual where the tablet should be with regards to flashed rom on tablet. kitkat bootloader or JB bootloader? Can you clarify in manual please? I have 2 Cubes, one on JB and one on kitkat. The kitkat has a bum, yet still working screen. I want to try it on it before trying on the Good JB rom Cube. So I know I will have more work coming from JB rom? yes?

Off course like all the lollipp firmwares, it's on jelly bean bootloader. Only kitkat has off course kitkat bootloader.

 

*edit: Stathis1985, is this something you were looking for? Still antutu score of about 22000, but hey it's working fine.

It's strange i guess, but thanks to Oma7144 i got about 27.000. Trick was to put the governor to Performance. This made a difference from 22.500 to 27.360 points in antutu benchmark(clean system install, set cpu and antutu installed only). That should make the new cyanogenmod 12.1 rom for the cube equally fast as the previous roms, just more options. 

 

Btw i used the kernel 38 overclocked 1800,789,720mhz.

Apps installed, antutu score 27.041.
- facebook
- pinterest
- instagram
- fstrim/fstrimmer
- es file explorer
- mx player and mx player codec arm v7
- nova launcher, speed as lightning set
- entropy fixer sEFix
- set cpu
- all apps updated

score antutu:
- ux multitask: 5087, runtime:3803
- cpu integer:2569, float-point: 2645
- cpu single-thread integer: 1895, single-thread float-point: 1627
- ram operation: 2359, speed: 974
- gpu 2d: 1120, 3d: 3796
- io storage: 451, database: 715

* developer settings activate, settings\About tablet\5 times tab on Build number to activate
settings\Developer options\windows animation scale off, transition animation scale off, animator duration scale off
* sEFix set entropy to 256 ( fixes the lags in ui)
* nova settings\look and feel\scroll speed and animation speed both faster than light
*Setcpu\min clockspeed 312, max clockspeed 1800, set on boot marked and performance as governor
* settings\Developer options\Advanced reboot activated (for rebooting in recovery mode, bootloader mode)

Further maybe a dalvik wipe and cache wipe you may do(reboot in recovery mode by pressing the power button, pushing reboot and push reboot into recovery mode)

 

Nice day!
