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.

-----------------------------------------------------------

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

Hi there,

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://xdaforums.com/showpost.php?p=36285435&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. :)

OK, cool. Done.
I flashed the preloader and now I am back to 1 GB RAM (max 970 / free 548).

On the GPS topic:
I used the gpstest app and did a clear AGPS / request AGPS step. Afterwards, it took about 2-3 minutes to get a fix.
And while driving home, I constantly had 6+ satelites in view and an accuracy of about 10-15 meters.
In short: GPS is working as before (i.e. before=my old 4.0.4 ROM)

Thanks again.

Guys,

What is the build number of this custom rom based on ?

I just got a B92M with 1GB and preinstalled with JB 4.1.2 . Build number is B92 20121222- 160954

Any advise on how to root this Jelly Bean ?

I'll check out the fix. So far I have no issue with my GPS.

Checked the GPS fix.

I tried out with two units of B92M, one with GPS fix and another without the fix. Result is somewhat non-satisfactory. The fix does not seem to help much in alleviating the GPS fix issue.

I tried out "GPS Test" and cleared AGPS & redownloaded AGPS data. This seems to help better as I could get the GPS info faster this way.
Haven't tried out physical antenna mod, tho.

I will keep you guys posted on this.

Steelburn,

Can you advise what build version is this ?

My phone comes with Build 20121222.

Would like to just root and repartition to 2.5GB and external on SD. Can you advise how ?

Best regards,

Lim

    Hello, I have not tried this particular ROM, but go to the Messaging app, then hit menu button, go to Settings. There should be an option in there to vibrate and ring; un-check the vibrate option. Almost every ROM for any phone I've had included this option here, in the settings for the Messaging app.
