RoadNav S150 // I802 Running Android 2.3.4 (MCU: 0421, IAP: 0002, Model Name: I802, F

Hi,

My name is Dimitris and i would like if possible to have some answers since you are high engaged with S150 as i can see on forum. I am trying up to 3-4 days to reach a conclusion if is good to "jump" to 4.0.3 Android F/W.

I Own a S150 - I802 Android with pre-installed 2.3.4 (Not Rooted) Android version with details as bellow:

RAM: 512MB

MCU Version : 0421

IAP Version: 0002

Model Name: I802

Flash Version: S009.

Version Number: GRJ22.V2.02.03-20130423

Kernel Version: 2.6.35.7-gb0f15e2

AM@rdjdz120033 #1

DVD Version: 1227

Here are some of my questions/concerns:

1)Root: I tried to root with up to 15 different APK's but the only one worked after the reboot was Baidu Root (All versions even if the Chinese . What's your opinion? Have you tested it on 2.3.4? Which APK you use to break 2.3.4 version?

2)Trying to make an SD boot-able i have the bellow questions:

a)Which are the differences between SD_FLasher and the workaround that provided in forum (Linux-wise). I have made the 1st one with the SD_Flasher. Is there any difference ? Should i have to make it ONLY via Linux shell e.t.c ?

b)What's about config folder? I have rooted my device and copied 7 files (xml & *.conf) into it. Is that correct ? Should i copied them in new SD so as to flash them or i should take the XML's from the ZIP files that i downloaded ?

c)What about MCU. I downloaded from a forum some MCU.bin files but i cannot see mine (0421). Will i have any problems if i leave MCU to be patched with the files that are on ZIP or i have to find somewhere and somehow the correct MCU.bin for my I802 ? As i read MCU needs to be OK so as no problems appear. Is that correct ? It's a critical issue i suppose. Is there any way to keep my default 0421 MCU version ?

3)If i "jump" to 4.0.3 all applications for CAR like (Radio, Equalizer, Speakers Calibration e.t.c are pre-installed or i have to find them on internet and re-install them ?

4)On 4.0.3 is there any issues except iGO that as i see is exists a workaround ?

5)I contacted local distributor that i have bought I802 and he told me that he needs up to 70€ so as to H/W and S/W upgrade my model to android 4.x versions He didn't tell me what kind of H/W upgrade will made (i suppose RAM that is quite small)

6)On 4.0.3 as an experienced use did you noticed any delays that are prohibitive to install 4.x versions ?

7)Without entering any SD so as to patch/upgrade/downgrade any Android S/W is there any procedure so as to enter device in Recovery mode ?

8)After Installing 4.0.3 did you thing that i will loose Wheel Controls ? I drive a Toyota Corolla E12 (2006 model) and till now i use Wheel Controls as it should. Probably it's a CANBUS connection right ?

One last question/concern.

I feel to be as accurate as i can so i was trying last day to find in all folders of my HDD including all / (root) directories and never find MCU.BIN

I find in a sub-folder called MCU somewhere into my system folders including some (4-5) files but i don't know if i have to zip them file and make zip to bin.

Have you identified the folder that MCU.BIN is kept so as to crop/paste in new installation SD_Slot and make a correct Flash to 4.0.3 ?

I would be pleasant for your reply since i am in a very big mess

Thanks in advance for your answers.

My Kindest Regards.

Dimitris Vampoulis
