HDC Galaxy S3 EX/Star B92M Android 4.1.2 JellyBean Update, Rooting, and GPS Fix
A very nice share from Xuan69, here’s a video tutorial (English) for updatingthe HDC Galaxy S3 EX/Star B92M to Android 4.1.2 JellyBean. The video will also teach you how to root the device, and apply GPS fix. This is a really great stuff for those who own this phone, enjoy!

HDC Galaxy S3/Star B92M Android 4.1 JellyBean Update
For a refresher, the HDC Galaxy S3 EX and the Star B92M are very much similar to each other. Both are really close S3 knock-offs, featuring 4.7 inches screen with 1080×720 pixels in resolution. This JellyBean update adds the support for the following languages: bahasa indo/melayu, deutsch, english, espanol, francais, italiano, netherlands, portugues, brazil/portugal, turkce, puccknn and other asian languages.
All the files you need can be downloaded from this link, its a 400MB archive hosted on torrent.
Some reports say that after they had used this JellyBean firmware update on their phones with 1GB of RAM in configuration, the phone wont recognize that amount of RAM. There is already a support-discussion about this phone unit on XDA-forums. Here’s the tip to get the 1GB of RAM fully working:
- Download this archive file.
- Suppose you already have flashed the Android 4.1.2 JellyBean ROM, flash again what you can get on that archive except for the boot.img and delete as well the preloader_vanzo77_twn_jb.bin file inside.
- After flashing, go into recovery mode by holding the power + volume up button at the same time when booting the phone. Do a factory reset and reboot the system.
- Done! You now have a 1GB of RAM on configuration.
Rooting and GPS fix for the Star B92M/HDC Galaxy S3 EX is included in the video as well. Enjoy!

hi, have you tried root with restore by b1n4nry method? I had posted a link of it on how I rooted my HDC Note 2 PRO
Thank you for replying I will try this method if it works I will let you no
Any Updates to this? Maybe a workaround to fix this problem?
I have the same problem like william. My B92M has already Jelly bean installed (v4.1.2) – everything I tried failed. I used Binary v1.8 – failed. Binary v.1.7 seems to work well – but failed also.
i need it just rooted – all other methods failed too.

Hi,

I have the s3 EX v2. Rooted by FCT. nfortunately in chinese. Enter recovery by holding down menu. Is it possible to exchange recovery image with the same method as described? I have large battery drainage, haven’t got a solution to that. ( also disappointed at FCT, said it was 1,2 GHz but is only 1,0. Doesn’t answer email either)
Hi guys I found some one in the UK who can root your star b92m if you can not do it your self it did cost £15 + post but was worth it if you are willing to try him out and save your self from stressing email me and I will point you in the right direction konone@hotmail.co.uk
hai thare…can i flash this rom in my note2 clone mt6577 http://postimage.org/image/yfktd1lcv/
http://postimage.org/image/z57qpjqvr/
not so sure, can you tell me the source for that? If you plan to flash that, just be sure do a backup of your stock rom first so in case you end up with an incompatible rom, you can always go back.
Thank you, followed the whole process and managed to update from 4.0.4 to 4.2.1 on my HDC Galaxy S3 Extreme 1gb version !
Hi,
I have a Star G9300 Andoid 4.1.1 smartphone (alps E1920_V77_zlh_9p017_asx) 1G(RAM),

Dear William,
I have the same problem, but find nothing how to get 1Gb back…
I ave been checked but the instruction can not be understanding…
Is it posible to contact with Ian Albert Austria? maybe he can help us?
I asked about that problem but nobody answer yet….
Best Reg….
Doron
Thank you for letting me know I am not the only one with this problem doron if I some how fix this myself or get the correct info I will update you but I have tryed every day since I got this phone their must be away to fix this…
Dear william,
have you read this message? I have it but did not try it yet:
For anyone having issues with having only 512MB after flashing JB, this is what I did:
first Copy all the files except boot.img from / 2.5GB-data-perm-root folder into / b92m411/FILE NECCESSARI folder.
second Delete preloader_vanzo77_twn_jb.bin inside / b92m411/FILE NECCESSARI folder.
third Flash using flashtool untill the green mark appears.
4th Unplug your phone then boot into recovery (volume up + power).
5th Thurs factory reset, then reboot system Voila! Now you have 1GB of RAM. If you want 2.5GB internal memory (not phone memory), flash and preloader.img EBR1 only inside / 2.5GB-data-perm-root folder by Flashtool. Then boot into recovery, go to mount and storage, format / data. Reboot your phone.
If you try this let me know about the results
Best,
Doron
Dear doron
I have read about that but some reason the flash tool don’t seem to be working on my PC but I’m going to try it on the PC I did the jelly bean4.1.2 update on I will let you know if this works as soon as I get time..

Hello willaim,
I’d like to know how your phone is working after you fix the 512M problen?
have you try the GPS? is it working also?
i’d like to make the upgrade you told me,,,
Thank you,
Doron
Doron after flashing my phone on a windows vista PC the sp flash tool worked no problem GPS I do not use so carn’t help you on that one to be fair I have grown to hate this phone now for many problems with this phone like the middle housing breaking and no replacement can’t be found and the screen has crack and the cost is stupid for a replacement one and and the phone has no extended battery so all in all if you have had problems with this phone my advice is get a better phone cause from day 1 of having this phone has been trouble for me
Sorry to hear about your phone. have you try the JIAYU G3S phone? It seen that the quality is defferant. I also have several problems but it working. also buy a new one Star G9300+.
My son is checking it but i think it work butter that the B92m.
I will try to applay the patch and maybe i will buy new one….
I have samsung galaxy S3 Clone (not sure which model exactly). The GPS does not work in my phone as well. Can you suggest if this fix will work for it as well.
Also I do not have the box or any original accessory. Is there any other way to find out the model number?? I looked beneath the battery but could not find anything.
The 400MB archive hosted on torrent fails to download with an error “Existing file with incorrect size”.
Hi Ian
can I ask you whether you has got the original rom for STAR G9300 (512 Mb, 4,8″ display?
I’m facing with lot of problem to find it.
thanks
