[Android Q&A, Help & Troubleshooting] sisilk:
Hi everyone,

A couple of days I posted in XDA Assist and was asked to seek help here. Therefore, I'm posting my original post here, along with some updates at the end.

Original Post:

I've got a reasonably unknown Tablet PC.. Here are the specs and miscellaneous information;

Name: Ainol Numy 3G P97

Internal Memory: 16GB

RAM: 1GB

GPU: Mali-400 MP

SoC: MediaTek MT8382 ARM Cortex A7 @ 1.3Ghz (Quad Core)

OS: Android Jellybean 4.2.2 (I'm pretty sure it's a Custom ROM)

Kernel Version: 3.4.5

Build Number: Numy_3G_P97_V1_2014090215

Custom Build Version: 1.19_20140822

Root Access: No (I never tried to root the device, never had a reason to do so)

I've been searching around for ways to upgrade the OS from Jellybean to Lollipop or higher. I've searched extensively within XDA Developers' various forums, but there doesn't seem to be any post in relation with my device.

I took to the internet and found some websites offering Flash Tools, Firmware (nothing above KitKat, or so it seems) and Android Studio. I've tried (in vain) to go through some tutorials on YouTube, but haven't come across anyone who's done anything with this particular device.

However, I have a rough idea rattling around in my head of what needs to be done, but I just need guidance from the Developers here to tell me how to get about doing it.

I have the following software downloaded;

1. MediaTek USB Drivers and Flash tools

2. SP Flash Tool v5.1620

3. Official Android Jellybean 4.2.2 System Image for the device

4. Android Lollipop 5.0 System Image (the site I downloaded it from says the Firmware is for a different tablet pc, but with the same specs as my device)

5. Android Studio (latest version, direct download from Google) - I read in some sites that Android Studio would help a lot to install a Custom ROM into any Android device, hence the download.

I'd greatly appreciate anyone helping me out in this endeavor. I'd like to install Lollipop (at least) on my Tablet PC, in order to gain some functionality as well as improved performance (hopefully!), as the current Jellybean OS is terribly laggy. I've seen other Tablet PC's with lesser specs running Lollipop smoothly, so I'm hopeful that there might be a silver lining to an otherwise very dark and sinister looking thunderstorm.

Updates:

While waiting, I've tried a few things. I downloaded the following;

1. Android SDK Tools with Platform Tools

2. Android Lollipop system images x 2 (.img file format) (similar specs to my Tablet PC)

3. Android Lollipop system image x 1 (.zip file format) (similar specs to my Tablet PC)

4. Android KitKat system image x 1 (supposedly the original and official KitKat OS for my Tablet PC)

5. Kingo Root app (Windows version)

Here's what I tried:

I tried using ADB to sideload a Lollipop system image (.zip file format) through a custom recovery already installed on my Tablet PC. Each time I tried, the installation would just stop with "Installation aborted". No matter what I did, I couldn't get it to work.

Next, I tried to "update" the current OS (Jellybean 4.2.2) to KitKat using the "official update" I found on the net, for my Tablet PC. I used SP Flash Tools to try and load the file, but that didn't pan out, as there was something corrupted in the Scatter file. Each time I tried to load the Scatter file, I'd get the error message that it was corrupted. Didn't know what else to do.

Following that, I read some articles where rooting the device in question was suggested, so I searched around for a bit, found the Kingo Root app, used it and rooted my device. Then, I tried using ADB again, this time using a more traditional method of custom ROM installation. But once I got to the Fastboot commands, I couldn't get any further. My device did boot up in Fastboot mode, but I got lost after that.

As of yet, my device is still running Jellybean 4.2.2. I've refurbished it by doing a master reset, but I'd really like to get Lollipop in, if it's possible. Any help would be much appreciated.

Thanks!
