Phone [ROM] B92M No Cholesterol Jelly Bean 4.1.2 with 2.5GB internal

-----------------------------------------------------------
1. INTRODUCTION
-----------------------------------------------------------
I got myself a Star B92M China-brand phone. The phone features are awesome,
with Android 4.0.4 ICS ROM; HD display; 1GB RAM; and very affordable price
-- I couldn't ask for more.

However the stock ROM has a few caveats:
- It sends out SMS to the phone manufacturer each time I reboot the phone.
- There are a lot of junks inside. I don't need those China apps!
- The internal storage is pretty small. I got my storage full in no time.
- I want more recent Android ROM.

Of course there are solutions to this. I found them, I tried them out. I give
them credits (see below in credit section). More than that, hopefully I can
get my phone to do better. I'll just customize this.


-----------------------------------------------------------
2. FEATURES
-----------------------------------------------------------
- Jelly Bean 4.1.2
- 2.5GB internal storage partition
- Back to basic - trimmed down apps
- Will not SMS back to manufacturer
- Use external SD as primary phone storage, instead of the remaining 85MB.

-----------------------------------------------------------
3. INSTALLATION INSTRUCTIONS
-----------------------------------------------------------
3.1 REQUIREMENTS
The following are installation requirements:
Requirements:
- Microsoft Windows XP/7/8
- At least 400MB to unpack the ROM
- MT6577 USB VCOM drivers
- Mediatek SP Flash Tool v3.x
- ROM zip file
- USB cable that comes with the phone


3.1 DRIVER INSTALLATION
a. Unpack the driver ZIP file.
b. Run InstallDriver.exe

3.2 ROM INSTALLATION
a. Extract ROM zip file.
b. Switch off your phone. Then, connect your phone to your PC.
c. Run Flash_tool.exe from "SP Flash Tool".
d. Load "Scatter-loading" file named as "MT6577_Android_scatter_emmc.txt"
available inside the extracted ROM folder.
e. Click "Download".
g. Disconnect your phone. Take out the battery for a while, and put it back.
h. Reconnect your phone. ROM downloading process should start now.
i. Wait until a window with "green donut" appear.
j. Disconnect your phone.

3.3 POST INSTALLATION
If this is the first time you install a "2.5GB" ROM, you may need to reformat your
data partition before first use. Follow these instructions:
I. Enter ROM Recovery
a. Press Volume-Up button. Press Power button. Hold them together until
the green Android robot appear.
b. Release the buttons. You should be entering the recovery boot.
c. Use "Volume-Up" and "Volume-Down" buttons to navigate.
Press Power button to enter submenu.

II. Backup your existing data.
III. Wipe data/factory reset.
IV. Restore backup data.
V. Reboot system now.

NOTE: During creation of the ROM, I did not go through backup/restore process. I had the data
partition just wiped out. Therefore, please do not ask me if your backup/restore doesn't work
on you.

-----------------------------------------------------------
4. DISCLAIMER
-----------------------------------------------------------
I shall not be held liable for anything that happen to your phone, your PC, your cats/dogs,
or even the fat in your belly -- should you choose to use or not to use this ROM. While you may
ask in forums, or even email me about the ROM, I am not obliged to respond to any of your enquiries.
Any respond given by me is voluntary, and will be done at my own pace.

Please backup your applications and data.

-----------------------------------------------------------
5. CHANGELOGS
-----------------------------------------------------------

16 Jan 2013 - v1: Initial release.


-----------------------------------------------------------
6. KNOWN ISSUES
-----------------------------------------------------------
- Very upsettingly slow GPS fix. (Will work on this during the weekend.)

Thank you!

Does this include the latest GPS fix from the Spanish forum?
================================================== ============

Hi,

THANK YOU VERY MUCH FOR THIS!

You saved my a?? today - I killed my b92m and was not able to get it back to work again. Already the recovery mode failed .... and then I found this. All I can say is: Very cool work.

I was able to install it without any real issue on my phone (just one issue - see below).

Now about the issue:

I also have the 1GB RAM edition (at least my 4.0.4 Image showed up 1 GB RAM in every tool).
Now - after having flashed your package - I see only 512 MB of RAM.

Any idea how to fix this?

Thanks again!

Just checked mine using Antutu Benchmark.
Under Info -- System Info.
Check under Memory size (available/total). What do you see there?
I got 456.5 / 970.7 (which means roughly I got 1GB RAM total). Let me know your result.

OK - here is what Antutu tells me:
RAM size (available/total)
77,3 / 462,7 MB

Flash preloader from 2.5GB folder. You shall be fine.

Anyway, for the OP, how about the camera? Is it 8MP or 12MP? If it's 8MP, can you make a flashable zip for those who want 12MP? And any luck with GPS issue? Since the first day I got this phone I never have GPS fix. Oh, I almost forget, is this ROM deodexed?

Thanks in advance, dev.

Help ! )

I am new to all this flashing thing - thats why I was so happy when I found your work here - the "all in one package".

When you say "flash preloader ...", do you mean "take preloader.img from a 2.5gb-data-perm-root.zip file" and just flash that using the flash tool? Or do you mean preloader_vanzo77_twn_jb.bin from your zip file?

On the camera:
I can select only up to 8 MPIX when I go to camera settings ... is this what you need?
How do I create the "flashable zip"?

On the GPS:
Need to test it.

And WTF means "deodexed"?

Yes, the first one, from 2.5GB folder. If the issue persists, copy preloader from 2.5GB to JB folder, then delete the original one (the original preloader from JB something-vanzo-blablabla). Reflash using SP Tool and make sure the preloader is from 2.5GB folder. Reboot. I posted about the issue in another thread, perhaps you can relate to this too: http://forum.xda-developers.com/show...&postcount=503

P.S. Wipe data if necessary.
P.S.S This is very advanced. If you don't know what you're doing, stop where you are! You might end up bricking your device.

And yeah, the rest of questions I meant for the OP. You can care less.
