HDC Galaxy S3 G9300 - ROOT

Has anyone got a root method that works for the HDC Galaxy S3 G9300?
Have tried Bin4ry v18 and another script but they didn't work.
The phone has JB 4.1.1. The Kernel is 3.4.0 dated Dec 3 2012. The build number is; e1920_v77_zlh_9p017_asx_20121203
Thanks for any help or advice.
Is now rooted, read on..

Me too. I've spent probably 6 hours today messing around with the 1.8 version script, on both windows 7 and Linux. It always fails the same place, with mount permission denied ... are you root?
I have other issues with the G9300 that I'd like to tackle, like WiFi range, but digging in requires root access. Here's hoping somebody smarter than I can find a way to root this thing.

Same here. I need root to build a custom CWM recovery.
Anyone has rooted phone that can help rip out the rom?

..

Finally. I've rooted my HDC G9300.

My phone is now nicely rooted with no problems. But it's not an easy process.

The tutorial isn't clear about how to run Android Kitchen. In the Android Kitchen folder is a script called 'menu' that has to be executed by cygwin. Launch cygwin first with the .bat file in its install folder. Then, navigate to the 'menu' script. Hint: '/cygdrive/c/<path to Android Kitchen>/menu'
Nowhere does the tutorial say to copy 'Root_Superuser_3.1.3_Busybox_1.20.2-Update1-signed.zip' onto your sd. You will want to do that before beginning the final recovery step.

Its great you figured out a root method, and thanks for sharing it :good:
I have just run through it on my phone and all has gone well until I got to where mobileuncle tools flashes the recovery.img. It needs Superuser access to do that and I don't have it. I am thinking it must be something to do with the Menu script you mentioned. How to you run that script? What is the command for it?
Thanks for any help!

Sounds like you're 95% there

From what you've written I will make a few assumptions. It sounds like you successfully did the rebuild with Android Kitchen, where it created a new recovery.img. And then you used SP Flash Tool to successfully transfer the new image to your phone.
You don't need mobileuncle. It's a great utility to have, but you don't need if for this process. Install it later when this is all done.
If the above assumptions are correct, you already have downloaded the modded recovery to your phone and you're 95% done. It sounds like all you need to do is put the zip install for su, superuser, and busybox onto your sd card, boot into recovery (upvolume+power), navigate to 'install zip from sd card', install the su-superuser-busybox zip, and reboot.
If that doesn't work, I suggest working your way back up the chain – re-downlod the new recovery.img; if that fails, rebuild the new recovery.img; etc.

Finally, you rooted the phone. Do you think you could upload the rom somewhere? Others can just download it and flash without going through the entire process. Good Job!!

Hi - Yes you are right, I have created the recovery.img and transferred it to the phone.
Thanks for the tip that I don't need to use mobileuncle.. So I have booted up into CWM and have the su-superuser-busybox zip on my sd card. Trouble is CWM doesn't recognise the sd card and says E: unknown volume. That is strange because android sees it fine when the phone starts.
I am still wondering if my problem is from the the android kitchen part. I wasn't able to run android kitchen. I think I better run through the process again. How did you bring up the 'menu' in kitchen? I ran cygwin first and then navigated to kitchens path and used /menu and also ./menu but just got an error message. Even dumped all of kitchens files into cygwins root directory in case I had messed up the navigation path but still got the same error message whenever I tried to run menu. How did you get it to run please?
Thanks for your help :fingers-crossed:

I have uploaded the recovery.img that I created here. Remember, because it works on my phone is no guarantee that it won't break yours. You use it solely at your own risk. Also, you will still need to use CWM to install the su+superuser+busybox zip from your sd.

Next problem - no 3G
Having the phone rooted, I've gone on to the next problem that has no ready solution.
That is, no 3G. I use the AT&T network in the USA. AT&T uses WCDMA on 850MHz and 1900MHz for their 3G service. The HDC G9300+ doesn't support WCDMA at 1900MHz, which is the band that AT&T uses most. Where I am (Phoenix AZ) there is only 1900MHz service, which means that I can't get any 3G. Only 2G "Edge".
The problem *might* be remedied through software - or maybe not. If the MTK6577 radio doesn't support 1900MHz in some hardware sense, then the game is over. But I doubt that for two reasons. First, from a marketing standpoint, the AT&T network is too big to just ignore when designing a generic platform like the MTK6577. Second, from a hardware standpoint, the transceiver frequencies are synthesized from one base oscillator through a set of on-chip frequency multipliers and dividers. If the MTK6577 can generate frequencies in the 2100MHz band it can almost surely generate frequencies in the 1900MHz band. What's required is a software driver that properly sets the multipliers and dividers.
My bet is that somewhere out there in the world there is a software driver for the phone's radio that can set the chip to work in the 1900MHz band.
Can somebody find that driver so that we can bundle it into a ROM for this phone? Or a tool to adjust the driver that's bundled with the phone?

Please tell me

Thanks for uploaded your recovery file. I thought I would try that before going through the process of redoing mine. This time it kicked straight into CWM without any sdcard errors, so was able to install the zip file. It is now nicely rooted and has been running for several hours, and as yet I have found no problems.
Great job and thanks for sharing your knowledge :good:

First time I purchased from them, found them very good and had no problems. Took about 15 days to get it. Considering there were xmas & new year holidays at the time it was pretty good.

How to root your HDC Galaxy S3 G9300+
For those wanting to root their HDC Galaxy S3 G9300+ phones follow these steps;
Download wseverin's 'recovery.img' from post #10.
Download my 'MT6577_Android_scatter_emmc.txt', 'su+superuser+busybox.zip', 'SP_Flash_Tool_v3.1224.01.rar' and 'MT657x_USB_Win7_Driver.zip' files that I have attached to this post.
Install the USB drivers to your computer if you don't already have them.
Copy the su+superuser+busybox.zip file to your phones SD Card.
Run Flash Tool (Flash_tool.exe) in administrator mode.
Load my scatter file.
Next, backup your original recovery file (This is very important in case something gets messed up) Do this using the 'Read-Back' function. Select Hex and enter 0x1588000 for Start Address and 0x600000 for Length. Before clicking the Read Back button, shutdown your phone and remove the battery and USB cable. Next click Read Back, plug in the USB cable and replace the battery (But do not switch the phone on) The software will backup the file and come up with an OK window if successful.
Next flash your phone with wseverin's recovery.img. Do this from the Download tab in Flash Tool and tick the Recovery option. Before pushing the Download button you will also need to shutdown the phone, remove the battery and USB cable as above.
Next start the phone holding the volume-up + power buttons. This will boot the phone into CWM. Choose 'Install zip from sdcard', then 'choose zip from sdcard', navigate to the su+superuser+busybox.zip file and select yes to install it.
That's it! So easy!!
If you followed the steps correctly, after you reboot the phone it should have root access.. However, be warned that your phone could be bricked if something goes wrong or your phone is a different model, so do this at your own risk and backup your original first!
PS: thanks to wseverin for the modded recovery file and being the 1st to root this phone.

Do I detect a hint of cynicism?
It seems to be a decently built phone. The display is good; actually better resolution than many competing models. Fit and finish are as good as you'll get anywhere. The capacitive touch screen is just fine. GPS, WiFi, and Bluetooth all work well except that the WiFi range is a bit anemic. Software is pretty much standard Android Jelly Bean. I consider it worth what I paid for it, especially since I am not about to spend 3X that for a cell phone. Oh, and it actually makes and receives phone calls!

Hello,
First of all, please excuse my english...
I have a Star G9300+ smartphone with the same JB 4.1.1, same kernel (3.4.0 dated Dec 3 2012), same build number (e1920_v77_zlh_9p017_asx_20121203) than yours, but 1Gb RAM memory.
Could I use the same method to root my smartphone? How much RAM have yours?
Thanks!

Yes mine is also 1Gb RAM. I have read that HDC and Star are the same, however I don't know this for sure. This is where I purchased my phone;
http://www.fastcardtech.com/goods.php?u=53399&id=8113
Does yours look the same??
If yours looks the same you could always try it I suppose, but make sure you backup your phones entire ROM first. That way you can reinstate the original in case it doesn't work.

Telsda A198

I bought a chinese phone Telsda/TSD A198 . The firmware reports it as an MT6589 CPU but the computer reports it as a spreadtrum phone. I need to root the phone to get rid of some apps on this to make space. Also without rooting is there anyway to backup the stock rom on my phone before I mess up to root? I have seen a method on XDA but that requires root. Now I am trying to backup to get to rooot !!!! Also I have also researched researchdownload but without a ROM backup and not knowing which CPU model to flash its impossible to it right. I also looked into mtkdroidtools and it tells me "unstructured rom backup not possible" , so I am guessing its a fake MTK CPU that is being reported by tweaking the firmware.
This is the link to the phone

Any help is appreciated.
Thanks

I also interesting for this phone, but I have some doubt about the specs of this item. If you could clear some important properties for me, such as:
Does it have GPS functionality?
If not, this indirectly indicates that CPU is not MTK-based (likely Spreadtrum SC6820 if 3G functionality is absent or Spreadtrum SC8810 if it is present)
What is the real width of the phone?
It seems to me it is about 64mm, not 60.8 (as described in seller specs)
What is the RAM size?
Does it have 256 or 512MB RAM?
What is the real Andriod version?
Does it have Android 2.3.X disguised as Android 4.X.X?
I will be grateful for your response.

Ok, first my honest suggestion dont buy this phone it has pathetic performance. For the same price go for a real MTK6577 dual core. ANyways below are the answers to your question
> Real CPU frequence seems to be 1GHZ
>Mali 300 GPU
>no 3G
>no GPS
>256MB RAM and 256 MB ROM
>I am not sure if its real JB and I cant figure it out but it says JB 4.2.1 and the kernel is 2.6.35.7 and hence I guess its a fake JB. The funny part is under baseband version it says "MT6589 1.5GHZ quad cores" !!!! offcourse it means the firmware/build.prop has been tweaked and is reporting false values. Also when I ran Antutu it gives a score of about 3500 which is useless when compared to what is required to run games ..etc. I hope I have helped.

Thank you much - you helped me to avoid hasty purchase. And good luck in rooting your device.

Finally I was able to stitch a ROM, using bits and pieces from different sources and its perfectly working. I only need to build a CWM recovery image based on the recovery image I have attached. Can someone help me do that? so that I can do a nandroid and ump my rom in case someone needs to recover their telsda A198

I need help. I have the same smartphone. But I need it to flash. Do You have the firmware for it?

ok looks like lot of people have issues with this phone. Its a junk phone, all fake stuff on it. ANyways I will upload the firmware images and then you guys can use those to flash on your phones. Below is what I have done
1> Patched a 4.0.4 ROM which works perfectly
2>Removed useless preinstalled apps
3>rooted
4>Perfectly working dual sim,GPRS,WIFI,Camera,Camcorder .,..etc etc
4>The issue is with the IMEI, because of the way its stored you guys will need to use your own NV files.
The only thing I havent been able to do is get a working CWM, but you dont need it as you can flash the firmware images using researchdownload.

Braindia, you even pierced smartphone using researchdownload? Maybe I need a USB driver or researchdownload? What have you used? I can't understand how to enable the firmware on this phone: food & + -test menu; food & - picture with your phone and the triangle, but windows does not find the device driver.

Here you go, you flash at your own risk. If there are bricks/issues you are responsible for your own device.(Standard disclaimer) . I have uploaded all the files except system and NV, system image is kind of big and I am trying to figure it out where to upload it.. You dont need to worry about NV unless you completely erased the flash(never erase the complete flash or format it). If you havent done so then you are good to go.
Please google to find researchdownload and use it to flash the attached files. I wont be able to write the tutorial on using researchdownload so google is your friend.
I have also uploaded the gapps zip which will get you up and running with google play store. You need root to copy these files directly into system/apps folder.
I will be able to upload a system file which works, not the patched one with google play store, root ...etc etc . You do that on your own, I will help you do it.
Thanks !

Tutorial researchdownload not needed. I installed the USB driver and researchdownload. When the phone is loaded, I can connect it to your computer . BUT when I try to flash the phone with the help of researchdownload I need to enable firmware on your phone. In the mode of firmware (if I understand it correctly) phone is not detected by Windows. I wanted to know what USB drivers and version researchdownload used you, and as included mode firmware on your phone.
I have the original firmware.

your phone is probably not detected due to 2 reasons
1> windows disabling non signed driver.. if thats the issue while you start the PC keep hitting F8 you will be shown various options
Select disable windows driver signature enforcement
2> Second reason is you need to add an entry in adb_usb.ini file I think its 0x1782 which is for SPRD enumerator. There are tons of links for this one of which is

getting root is simple, flash a CWM I have attached one, please note this does not work but it works enough to get you root. follow the below steps
1> Flash attached recovery
2> boot into recovery ... this will not show the normal CWM options but dont worry just connect to your pc
3> run ADB shell, you will be automatically in root mode
4> perform mount /system and then exit shell
5> push su binary & busybox directly to /system/bin (from the command prompt using adb push)
6>change permissions for su & busybox to make them runnable
7> exit from the shell and reboot
8> do adb install superuser.apk(optional this can be done later)
thats it you have su, and then you can sideload the superuser apk or you can do step 8 as above. Once you have rebooted and verified that you indeed have superuser you can flash the stock recovery back on the phone.
Note note note : The CWM recovery image is only for you to get root and it doesnt work and doesnt show the normal CWM options... you have been warned. You should flash your old recovery/stock recovery after you have achieved root.
Also can you give me the stock recovery image so that I can build a working CWM out of it. I overwrote mine and now stuck with another recovery which works but is not for this phone.
Thanks

1> Flash attached recovery

Hmm... I am not sure what is the issue please try attached drivers and pray that they work . use either 64bit or 32bit depending on your OS.
Also you said you have the firmware can you upload it ? I can do something more with the stock/original firmware, so please upload it

I installed a different driver for windowsXP and windows7, but the result is the same. Too much time for 54$. I buried this smartphone. So good luck to you on the path to custom firmware. One month firmware will be available my personal archive: http://files.mail.ru/A9FBE04381094135959559784E5F49A4

[Q] Backing up stock firmware (rom)

Hello everyone, this will be my first question/post since i just started using an android phone, my first andoid device is Blu studios 6.0 LTE
I am trying to get into the field of basic cellphone troubleshooting and understanding, i have a good understanding on ios, now it androids turn,
anyways i am planing to root my phone, but i wanted to know if i am able to create a back up rom non rooted, (hope that made sense lol)
i searched everywhere and only getting results leading to use titanium backup (which requires root) and clockwork recovery, which i also think requires root
there are some methods to create backup without root, but i don't think my phone is supported (only MTK?)
so i came to the conclusion that there are no methods to creating a back up stock rom of my blu studio? yet?
should i just go for it and root without making a backup?
or am i just understanding it differently, cuz i am thinking if you create a backup rom when you are rooted, you will have a rooted stock rom right?
instead of a rom that will have the fresh os from a factory phone.
is it important to have the clean rom? or it really doesn't matter if its a rooted rom?
also i have not installed driver for my blu studios yet, can anyone link me a good site to download the drivers? i went on my phone's company page, but no drivers.
google searched and the top 2 sites looked really fishy, they all had the same file for all model phone. rest of the search is just people also asking for drivers. . .
i am planing to use the swapper app to increase my phone's ram, its really laggy since it only has a gig of ram >_< other than that no other reason to root xD
A note to the moderators: i am really sorry if i posted this in the wrong section, i didn't know where else i could post this question.
Thank you for reading!

first you should write this thread on the Q&A....there is a way to root mtk devices using framaroot which you can find here http://forum.xda-developers.com/apps/framaroot/root-framaroot-one-click-apk-to-root-t2130276 ....if your phone is not a ubifs type system you can easy create a cwm for it then create a nandroid backup.....
hit thanks button if this helps you

Sorry still new to the scene, can you do a quick explanation on what mtk devices are? and ubifs?
i have the Blu studios 6.0 LTE phone
Edit: was checking what mtk devices are, so its model of the cpu? i used cpu-z to check and it say my model is MSM8926
"The models for MTK devices always start with Mt prefix, while that of Spreadtrum often start with SPD or SC." -copy pasted from an article
so i guess it's not an mtk device after all, does this limit my options?

Trojan
Had any one else had a warning about a Trojan hidden in device management 1.0
Have re flashed more than once trying to deal with chrome err_connection_refused problem, every time the Trojan is back, you have to use titanium to get rid of it.

Tablet is brick!
I have a P98 3G A9H8. I used the flash tool here to install the ROM using the "download" option & I got an error that the ROM is not there. I tried to start my tablet immediately & I could not.
Then I chose the "firmware update" option and it came back with a list of errors (3 errors). I tried to power up the tablet again- again fail- nothing happens at all. Not even attempt at rcovery.
In other words, by flashing this rom, my tablet is not BRICK.
Does anyone know of a way to unbrick it? I am thinking perhaps flashing a stock rom can resuscitate it? I googled but could not find its stock rom to download.
Any help will be appreciated.

This ROM is just crewed up!! So many different errors it is not funny. Don't ever touch this- it screwed up my tablet big time.

Lenovo S856 stock rom and fix bootloop / stuck

Hi everyone,
I just want to share about this Lenovo S856 LTE rom. Yesterday, I have accidentally uninstall 1 system app which is I do not know if it will make this device bricked and it is IDEA.apk and some themes app. Before that, I have also root this device using kingroot and all work fine as it should. Spent all night trying to find best solution as the device won't booting and just stuck at bootanimation and ended with blackscreen. Since this is my first time using this model, I also don't know it's quiet complicated to flash new ROM with QPST softwares.
But thanks to whoever who compiled this Lenovo s856 rom into 1 flashable file ( QSB file ). It's huge than normal ROM I ever found, it was 1.5 GB and I did successfully recover my device after several attempt and findings.
Firstly, download ROM - I can't include ext links here as I'm still new :angel:, you can find the rom Lenovo_S856_ROW_S138_141113 from google drive. Using IDM would be great to download this 1.1GB zip file.
2. Enter recovery mode by pressing Vol + and Vol - together and press Power button and reset device to its factory. ( format data/cache)
3. Reboot again and now enter Service Mode by pressing Vol - and Power button. There is 13 options available and selecting them using volume button and power button is for OK.
4. Choose number 5 ( factory reset ) and number 6 ( erase user data ) this is necessary as I tried once skipping this option and device keep rebooting non stop. I'm not sure what makes it rebooting and rebooting. maybe caches or dalvik not wiped completely using recovery wipe method.
5. Choose number 8, ( backup MRD data ) and next number 10 ( Save Parameter ) to backing up modem files into your external SD card.
[Edit] 6. Once you got your download file ready, extract it into your PC or directly to your sdcard ( external sd ).
7. Create a 'new folder' in sdcard and rename it to 'sdfuse' and copy .qsb ROM file you extracted earlier into sdfuse folder. So the path will be /sdcard1/sdfuse/romfile.qsb
And now, reboot into service mode. Now choose number 4 ( SD update ) and let's it do it work, flashing will take about 5 minutes.
and REBOOT!
Now, let see if you're having any issue e.g stuck at boot, please repeat the process once again and I'm sure it will fix.
And if phone not detecting your SIMcard. please boot into Service Mode and choose number 11 ( Load Parameter ) and REBOOT.
Good Luck! :fingers-crossed::fingers-crossed:

Low ram issue on my s856
Hi mate thanks for the info, i have td-lte model i think is cn set. I have problem with low ram issue, my free ram always below 300mb which causing game auto quit eg. Coc, boombeach. It started auto quit when free ram reach below 150mb. Need restart phone to restore free ram above 300mb then can run game but after a few play the game auto quit again, also having problem keyboard not display in game due to low ram. I find out that the vibe ui is consume alot of ram than non vibe, example open setting it consume about 66mb of ram, with non vibe from lenovo a536 just used 23mb of ram. Now im root and disable unimportant system app to free up more 300mb ram just to get some game run. When compare mine s856 without app running with a536, mine will get average 350mb(heavily system app disable)free ram but a536 without app easily get 550mb free ram. Any solution? Or how to downgrade to non vibe.

Need for MRD and Parameters data backup.
Unfortunately, restoring modem configuration (11 . Load Parameter) doesn't work for ROW firmwares installed on Chinese models.
Regards,
Luigi

Hello RidzVarn, unfortunately I read your post too late... :'(
I also flashed Lenovo_S856_ROW_S138_141113 because the stock ROM was the Chinese one. While the OS is far more stable and polished now, 3G/LTE functionality now is gone... GSM radio signal is also less stable than before.
I'm desperately trying to find the original Chinese stock ROM so as to backup MRD and Parameters but... no way, only ROW firmwares out there.
I'm wondering whether your phone is the same Chinese LTE version (MSM8926 CPU, 1 GB RAM, 8 GB ROM) of mine and, if you saved those MRD and Parameters data, you want/can share them with me in order to allow me to bring 3G/LTE functionalities back.
Thank you in advance,
Luigi

Hi Luigi,
Apparently, I'm not very sure if my S856 is China Set or not ( but well.. specs are same with yours though ). You can try to restore this MRD and Parameters backup files onto your phone.
Backup your own modem files first and copy paste them into separate folder ( e.g : 'sdfuse-backup' ) in case something going wrong.
Download here ( Google Drive )
Good Luck

Hi RidzVarn,
sorry for the late reply. Actually I managed to take those files out from a stock Chinese ROM, but simply saving/restoring them through the Service Menu doesn't do the job. I guess there are other file and settings in /system and/or in other partitions that are needed in order to make modem working.
In the end, I just reflashed a Chinese ROM flashing also GApps and SuperSU through TWRP, and I'm fine with the result.
I'd like to thank you, however, for your efforts to help me in sorting the issue out -- it was very kind of you.
Best wishes,
Luigi

Please try to:
pull the battery out;
wait 20-30 seconds;
plug the battery in;
plug the USB cable to the PC end only;
and keeping pressed Volume-Down...;
... plug also the microUSB connector to the phone;
release the Volume Down after 3-5 seconds;
check via Device Manager if a 'Bulk' interface has been detected.
If not, retry the same procedure but keep pressing the Volume-Up, this time.
If the Bulk interface got detected by Windows, use the MiFlash tool to flash your favourite firmware again.
Remember to disable the Windows' 'Driver Signature Enforcement' at the boot-up, and disable also any Host-IPS and Antivirus running on your machine.
Hope this can help.

Hi dxshah,
Weeww.. That's quiet buthurted. You can try to fix it using MiFlash tools as said by Luigi.
Always take a pre-caution step before flashing/updating ROM. Make sure your battery is at 80% and above or just plug in the charger while doing live update.[emoji1]
Thanks Luigi for your post, I didn't know and haven't discover that steps yet. Will try to find out more about MiFlash tools[emoji106] [emoji1]

You can find the download link to MiFlash (look at the bottom of the page) and a bunch of other useful information (well, the post is quite lengthy) here:

Did you flash a custom recovery (e.g. TWRP)?
If so, restore the stock recovery first, and then try again.
Cheers,
Luigi

Thanks for the explanation! i got my lenovo working again from chinese ROM which is horrible. Thanks guys[emoji8]

Hi Pjajiro,
Where did u put that .qsb file? Actually, you have to create a 'new folder' in your sdcard root and rename it to 'sdfuse' and put the ROM qsb file in it. And try again. [emoji1]
My apologies, I have forgot to include that step in this thread, and will edit the line asap.
If you still get the same error, then it might be caused from ROM itself. Maybe its not for your device.
