From The Wiki

Vanilla software is computer software that is not customized from its delivered form – i.e. it is used without any customizations applied to it. Vanilla software can become a widespread de facto industry standard, widely used by businesses and individuals. The term comes from the traditional standard flavor of ice cream, vanilla flavor.

P.S.: After some time of using this ROM:

Cleaned some of my old apps (mostly the free ones that sucked the battery dry and adjusted some settings), and I must say it's one of the BEST roms. It feel like a new phone! No, really!

I'm a stock ROM fan, I don't like to trade in stability for speed (usually the case for most custom roms), but I must say this is a great all rounder, speedy, stable, usual features (all working) directly from LG!

I tested Zeus (some LG widgets don't work, I think Battery stats or Network meter), all stock 20x, roms, all 10x roms, an clearly this one is a winner, granted you clean the rom with Titanium or something else!

My list of apps I froze (In romanian - English Translation, could be wrong!):

CarHome 2.3.4

WhatsNew 1.0

[ALARMS] Clock 2.0.2 - Alarm app still woks, disables that stupid standby screen I never use!

Start Screen, Advices 1.0 - Widget

Finance 1.0 Yahoo Finance

Fire Work 1.0 - LWP , I cannot select the ones I removed ....

Galaxy 2.3.4 - LWP , I cannot select the ones I removed ....

Gmail 2.3.6 - LG Email Is enough for me And I use it for Yahoo and Gmail

Google Play Books 1.5.4 - It's not accepted in Romania

Google Play Movies 1.4.9 - It's not accepted in Romania, doesn't work on rooted phones

Google Talk 1.3 - I never Use it!

Google + 2.4.1.27037 - If you use it keep it!

Magnetic Globe 1.0 - LWP , I cannot select the ones I removed ....

Music Visualization Wallpapers 2.3.4

Polaris Office 3.0.3146.0 - Try WPS office it's way better than this version!

Friends + 2.0

Rainy Day2 1.0

RemoteCall 1.1.0.40 (Build 89)

SmartWorld 2.1.01

SNS 1.0 - Use Facebook Twitter, or web interface it's better!

SpaceLiveWallpaper 1.0

Tree in Snow 1.0

Widget Photo Album 1.0

Widget Photo Frame 1.0

It Touch ItTouch.24.03.2011

News 1.0 - Yahoo news - don't need it!

News and Weather 1.3.04 It's Used for Clock App - don't need it!

Also can be removed without any side effects, I suspect these are used for RemoteCall, but I'm not shure:

Remote Input Service

Remote Screen Service

Remote UInput Service

RSstarter

Also, everything related to Hidden menu (I never done this but it should work):

I don't know the packages by heart, but I think it's:

Lge.Hiddenmenu.... - removed Hidden menu

LGE. HIDDENPERSONMENU -??????????

Camera (the one with circle icon), it' sused only in hidden menu

If someone could shed some light on the packages needed by hidden menu, or if they feel this list is not ok, or could make improvements, please do so!
[LG Optimus Black] Mr. Dimples:
Done flashing! Hope it works well. Thanks to mihaiolimpiu for the flashable zip and also thanks to agritux for the guide. Hoping for longer battery life compare to V20F. :)
[LG Optimus Black] agritux:
what about drm services and packages?

i searched about it. they say it drains battery and can be freezed.
[LG Optimus Black] Duarte777:
I´m currentl using this ROM, you guys want a Slim, clean and zipaligned v20S ?
[LG Optimus Black] agritux:
i tried but i couldnt make

because it is different from previous versions

it will be good if you can

thnx koila33

As the Technaxx Techtab Users we don't have any specific forum I’ll post in general upgrading forums.

As you know Technaxx Techtab is not too much developed but the creators in Germany ported the firmware to Android 4.

EDIT: The Technaxx Techtab it's a clone of other tabs (this guide is useful for some Newpads including P9 and also some Intex Tabs)

Here is the guide:

Do it by your own. If you brick your tab I'll wash my hands.

1. Download all the tools.

Firmware image

Flashing Tools and old firmware

USB Driver

2. Extract the USB Driver and the Flashing Tools

3. Execute in Tool_1.4 the flashing program named RKBatchTool.

4. In the window search for the Android 4.0 Firmware (3719_update-DS803_with_512MB_DDR,_2_touch_points-2012-7-3.img).

5. Connect your Techtab to your computer by USB and connect it to the charger.

6. Power Off your Techtab.

7. Press Menu and power keys together and wait some seconds.

8. Your computer will start recognizing the device, no light in screen of the TechTab.

9. If your computer doesn't recognize your Techtab go to Device Admin and upgrade the drivers with those found in the downloaded folder.

10. In the RKBatchTool the Device Number 1 will turn Green.

11. Press Upgrade and wait till the Techtab starts with Android 4. :laugh::laugh::laugh:

RK2918

The Technaxx Techtab it's a clone of some Chinese tabs including Pipo DS803, Newsmy Newpad P9, Hyundai H700, Tomtec Excellent 8 and Xiron Excellent 8

So some RK2918 Tabs with 8 inch screen may be compatible. :laugh:
[Upgrading, Modifying and Unlocking] Oma7144:
Technaxx Techtab, Newsmy P9 aka Pipo DS803 (OEM).

Odys-Xpress aka Pipo DS820 (OEM).

DS820 and DS803 are technically comparible. For verification: http://www.pipo.com.cn/product.php?id=73

Pls find attached the kernel extracted from the update.img provided in #1, so you can use it with different ICS images.

Maybe its worthwhile to try this ICS image. The image has specific config and firmware to run on an Odys-Xpress.

[Upgrading, Modifying and Unlocking] Oma7144:

This doesnt work in Intex itab 8"

Though Intex itab looks like exact clone of technaxx techtab,this ics doesnt work..After flashing this rom,it took half an hour for each boot.touch screen doesnt work.ics runs slow like anythung in intex tab..
[Upgrading, Modifying and Unlocking] Oma7144:

Could you pls upload the log of "dmesg" that I can see your hardware?

2.auto rotation not working

3.camera only in inverse landscape mode.

[Upgrading, Modifying and Unlocking] Oma7144:

Do you have a ring on your screen?

Autorotation: no function or wrong direction?

pardon me if i am wrong..in sys/bus/i2c/drivers i see sis809_ts folder of airpad kernel.i can unbind it also..if its possible to copy goodix gt801_ts drivers and bind it to the screen using adb,itab touch screen may work in oma ics..its a guess.please guide me ..

intex itab works with oma ics

oma rocks..!! intex itab works swiftly with this kernel_308_excellent 8_atp7658_5p_xirion..touch screen(Goodix gt801-ts) works smoothly..almost everything including wifi,hardware decoding,pinch zoom and even my evdo cdma usb dongle works smoothly..so most of other 3g dongles must work..hdmi i havent checked yet..camera works well..battery icon status is ok now..nand is shown as sdcard,but i hope it gets fixed on applying omas intsd-to-nand fix.i will check n tell

only prob remaining is auto rotation..it rotates in its own way..no relation to how we move the screen..also oma ics shows my ram as around 250 but my actual ram is 512mb.mild jitteriness on multitasking is there compared to gingerbread,but its not annoying much..

any ideas on correcting autorotation??... once again OMA rocks..thanks man..cheers to u:good::good::)
[Upgrading, Modifying and Unlocking] Oma7144:
Fine.

The ICS only see 250 MB RAM, this is ok. The rest is the ICS itself and reservation for video-RAM.

Could you pls upload the footprint of the system (take a screenshot of settings/about tablet)?

Could you also pls upload the dmesg log?

I will do a model-fix later on. In the meantime use attached app to fix the screen.

[Upgrading, Modifying and Unlocking] Oma7144:
Load until accu is full (LED out or at least 8 h). Then boot into CWM and wipe battery stats (advanced).

Have you been asked there for the firmware? I guess the support can help in this case.

Your tab has the sis809 touchcontroller (dualtouch), so try Oma ICS with kernel:

- kernel_308_excellent 8_atp7483_2p_xirion

- kernel_308_excellent 8_tomtec

- kernel_308_ds803_pipo

- kernel_308_p9_newsmy

@ sir OMA, i used your ICS with Newpad P9 kernel and my Kingcom Joypad C81 now working smoothly and also the touchscreen now working. Thank you very much sir! I will post here if i have encounter any problem with my tablet. I'm now on testing stage with any bugs on my tablet.

Here's the Update on the problem that i have encountered so far:

1. "Connection Time-out" when i go to Play Store.

2. Auto-rotate sometimes in a wrong position.
[Upgrading, Modifying and Unlocking] Oma7144:
Ok, now the value of your Joypad C81 has been increased dramatically ;)

Can you pls upload the dmesg that I can document your hardware?

Can you also pls upload the footprint of the system?

[Upgrading, Modifying and Unlocking] kobekoy:
- Here's the dmesg [pls see on attachment].

- Also pls see attached footprint of the system.

- I'm from Philippines.

- The auto-rotation problem has now been solved by using this fixer [Display orientator_v1.7.apk]

In Addition:

- The Google Play Store still problem accessing. I got an error " Connection Timeout".

- I also notice that when i go to Settings>>Storage,

The Nand Flash is my External Memory while the SD Card is the Internal Memory. I already used your fixes [format Nand, Fix Int/Ext.], but still same.

Dual Boot ICS

Isn't it better to test ICS as dual boot on SD card rather than wiping out a perfectly stable s/m? Do you guys have any idea on dual booting ICS(on SD card) with GingerBread on device. I have an Intex iTab(rk2918).
[Upgrading, Modifying and Unlocking] kobekoy:

Recovery key combination

What is the key combination for Recovery on Techtab with Android 4.0? When i press menu key on boot, my iTAB with Android 4.0.4 update shows just a belly open Android logo with a warning triangle. Nothing else. In stock GingerBread 2.3.1 firmware random buttons could be pressed at this stage to get Recovery menu. But, it's no longer working after the update. Since Techtab is similar to iTAB(though it isn't an exact clone), its key combination might work for iTAB as well as all rk2918 tabs with Android 4.0 ICS.
