AW: [ROOT GUIDE] How to Root SpreadTrum SP6820 on Android 2.3.6/4.0.1?

Hi Yekdall,

thanks 4 ur rom. I will test it but I need a few days because yesterday I completed the non-rooted system with all apps I need. And I have to say the phone is working great also non rooted. The apk.installer which let choose u to install on extern sd works great so I have no problems with space after installing tons of apps. Only WLAN is a bit laggy. The overall performance, built quality and touch responsness is superb for this low priced phone.

But I didnt recognize that SMS were sent by spy apps because I still had not installed any SIM card. Is this really true that the rom sends SMS ?

And at last because I did not check it: 3G (WCDMA) is not working with this processor, right ? Only slow edge is available, right ?

Hi, you can have a quick check to verify it. If you have a look at the applications menu, in the execution list, see if you can find a running app named "com.android.caivs.app".

If you check the permissions, you will see that it is allowed to send SMSs on your behalf, which, in fact, it does. There's some history in the internet about this app. It looks like it is not really a malware, but a SIM tracking app for the China market. Anyway, the truth is that it does send SMS messages from your device, as I have sadly been able to verify myself in another device I have. Actually, I found out about this app because I saw some messages been sent to chinese numbers in my bill.

Hi Yekdall,

I tried your rom. I flashed it 3 times but always I got a bootloop only. The system does not start. Maybe you have deleted too much things which were necessary for booting. Maybe you could make the rom only rooted. The other things (apps) could be deleted after installing. What you think ?

Edit:

When I got this phone from the seller, I had a prerooted firmware installed. I played around a bit and there was no problem. When I remember right the system was booting with the very first stockrom until I deleted the stocklauncher. After I had only bootloops. I think you should not delete the launchers and lockers.

I don't know how you extracted the pac.firmware and how you compilated it. But maybe you could try this implement this clockwork recovery:

http://ge.tt/api/1/files/6komeiS/0/blob?download
[Android General] Yekdall:
Arrggg... You are probably right and I deleted something I shouldn't have... :(

Well, thanks for testing it, I won't post a new version until I have tested it myself, which I'm still not able to do as I cannot make the ResearchDownload program to flash my device. It gets stuck on "checking baudrate"...

Anyway, the same program ResearchDownload unpacks and repacks. That's what I have used for modifying the firmware. Once unpacked, I used Yaffey to modify the system.img file.

Cheers.
[Android General] pogodancer:
Do you mean with unpacking that the single files are in Win7 in "C:\Users\Manfred\AppData\Local\Temp\_DownloadFiles204......." ?

1. If yes, should it be possible only to change some files in this path, f.e. the recovery.img and continue after to flash the rom ?

2. If yes, could you leave the system.img as it is but only root it ? Upload it for me and I could exchange it and flash the rom after ?

Hi Yekdall,

1. Be sure to have the drivers installed correctly (SCI-android-usb-driver-jungo-v4-.rar). Then your Win7-device manager should look like the attached picture when you have USB-debugging enabled on the phone.

2. Try another USB-cable. Often chinese cables and power-plugins are crappy.

3.

a) Start ChannelServer and ResearchDownload in Windows.

b) Take off the phones battery and place it in again.

c) Put the USB-Cable in the phone only.

d) Press the -volume (Minus = lower volume rocker) and keep holding this button.

e) Connect the other end of the USB-Cable to your Windows-machine. It should not take 1 second that ResearchDownload starts to flash your phone. Now you can release the -volume-button.

same device no playstore

Hi,

i have the same device but it does not have playstore in it but is really working fine. Can anyone give me a firmware link which has a working playstore. i will be really thankful to you guys
[Android General] pogodancer:
Hi hemya,

the original firmware which comes to me with the phone did also not have the playstore. BUT IT WAS ROOTED !!! And it worked like a charm. Do you have the app "rootexplorer" installed ? So it is the same firmware which I had before until I deleted the stock launchers. After I could not boot again.

If this is the fact with your phone I recommend not to flash the firmware because it is not rootable until now. It would be interesting if there is a possibility to extract your firmware for the other users here and me.

Activate "unknown sources" in settings-security and use 1MobileMarket. It is a fine alternative to the Playstore:

https://play.google.com/store/apps/details?id=me.onemobile.lite.android

[Android General] hemya:
no rootexplorer

Hi,

Thanks for the app it looks good but i do not have rootexplorer installed so i think this is not the same firmware that you had. If you can let me know the process of extracting the firmware from my mobile i will be really happy to have it uploaded on this forum for everyone. But i must say rest everything is working fine with the mobile i just needed playstore to work so that it would have been perfect for me.
[Android General] Yekdall:
Yes, that's exactly what I meant.

I have made some progress. Looks like my Windows 7 64bits didn't like the spreadtrum drivers, so I have set up a VirtualBox with Windows XP and voila!! I have been able to flash the firmware.

My progress so far:

- Added su binaries to system.img for rooting -> Half success. Binary is there, but both SuperUser and SuperSu apps fail to use it. Need some more digging...

- Removed caivs.apk -> Success. Not a rooted device, but at least I won't pay unwanted messages.

Almost there!!! :)

AW: [ROOT GUIDE] How to Root SpreadTrum SP6820 on Android 2.3.6/4.0.1?

Hi Yekdall,

thanks 4 working on it.

Do yo have an easy way for the user Hemya to extract the complete firmware from his phone 4 us ? Just to compare it with our rom.

---------- Post added at 10:54 AM ---------- Previous post was at 10:42 AM ----------

Hi hemya,

thanks 4 helping.

If playstore is important 4 u then I maybe can help you. First your phone has to be rooted. Download superuser-app and maybe rootchecker-app. Install them and reboot your phone. Then start superuser-app and try to update binaries with the info-button in superuser. Try it 3 times if you get an error. But if it succeeds your phone should be rooted and you can check that with rootchecker.

Let me know if you are rooted. Then I can tell you how to get the playstore.

[Android General] hemya:
Hi,

Even after trying for more than 20 times it is showing the error messages. not updating the binary. Anything else that i can try?? Or any other firmware with preinstalled playstore?????

AW: [ROOT GUIDE] How to Root SpreadTrum SP6820 on Android 2.3.6/4.0.1?

Hi hemya,

OK if you have rebooted after SU installing it seems that U dont have root.

So you can install the rom I have posted above. I have described how to install it. Be sure U have a Feiteng A7100 phone. In this rom playstore is included.

Gesendet von meinem H9500 mit Tapatalk 2
[Android General] Yekdall:
Hi,

I think I found out the reason why the su binaries couldn't update even though they were present. The boot.img file in the firmware seems to be locked and it makes the su binaries to be ignored (or so I have guessed).

Thanks to Android Kitchen I have been able to root the boot.img as well so now I can say I finally have a rooted (and working) firmware. Yupiiii!!!

Only thing is that I added both Superuser and SuperSu as I was unsure which one would work... so now I have 2.

Let me try to compile a pac file with just one and test it. I'll post a rooted firmware during the day.

Cheers

if Yekdall's rom does not fit with your device and you have a sp6820a-device you can try this firmware:

[Android General] pogodancer:
Sorry I cannot help you. There are 2 possibilites:

1. You have another hardware. I had originally firmware: 6820_2.3.5_c910_hteng_s5_en_4.0_v01 and baseband sprdroid_base-user 4.0.4 MocorDroid2.3.5 MT6515_C910_HT_EN_4.0_V01 test-keys. It differs from yours. So you should contact your dealer to send you a link for the firmware.

2. Your hardware is defect.

It's because there is different versions of android on Spreadtrum processors.

To use Z4Root, android must have a security hole used to bypass security and inject the root utilities.

This bug has been fixed on newer roms for Spreadtrum, so there is no way to root them with z4root.

I have started a new thread on which I list every possible way to root a spreadtrum phone. http://xdaforums.com/showthread.php?t=2165554

Hi, unfortunately I have not been able to get a copy of the v05 firmware. I've also tried some suppliers, but still no luck with it.

Nevertheless, I have seen in the russian forum of china-phones that they have also gone ahead with the rom I uploaded and got the same issue with the green colors.

They have sorted it out with this app: https://play.google.com/store/apps/details?id=com.netmanslab.sa&hl=es

Not sure if it will work, but as it is a free app, it's worth a try.

[Android General] NuttyBunny:
Just killed mine (T101)

Yesterday I got my new Tesveden T101 phone http://dx.com/p/196938 , it's a SC6820, it had a Mocodroid 2.3.5T firmware (no, no, I don't have the information anymore).

The phone had Android 2.3.5, and it faked the version string to 4.0.1, so zergRush wouldn't run.

It's a SpreadTrum, I tried almost al known methods to root it, you name it, I tried it.

I had only two more options:

1. Recompile zergRush to leave the version verification off and just force it to use the 2.3.5 settings, but this would have implied getting a dev toolchain, and I wanted to do things quickly (in the end I think this was the sanest choice since maybe it was vulnerable to zergRush, providing it didn't barf on the Android version)

2. Use your ResearchDownload method to install CWM and then root it the old way, but something went wrong.

I installed the drivers and everything on a VirtualBox windows XP 32bit VM, I even had adb access. I also disabled USB 2.0 which made adb cry sometimes. I tried the Brazilian guy Root method (both), from the .bat file and with the individual commands, I tried DooMLoRD scripts, but they all used zergRush. I even tried with a viperMOD_PrimeTime which wasn't for the SpreadTrum but I thought WTH...

It doesn't have fastboot as well, just a crappy test and the download mode.

In the end I had an unrootable device until I returned to this post. I tried the options, none worked, and the last thing was using the ResearchDownload option, so:

I downloaded everything needded, and tried several FDL files for the test. In the end I got it working with Set1\fdl1.bin and Feiteng-A7100-SC6820-C910\fdl2.bin.

And then, I started trying the cwm-recovery files.

They do flash, but after trying to enter recovery it didn't work. I thought that maybe I was pressing the wrong buttons, I tried and tried. In the end I decided to look if it was still working, and ... well, I found out that it's stuck in a boot loop

It turns on, vibrates, and the phrase GOOD LUCK appears on the screen. Normally it showed an animation with an annoying sound and went to android, now it just sticks in the good luck screen, it turns itself on, and the process starts again.

I'm trying to contact dx.com to see if they can send me a working firmware to reflash it, and perhaps modify it beforehand to have root access.

If you didn't read correctly, no, I didn't make a full phone backup because after I tried to flash cwm the phone didn't start anymore, not on recovery, not on Android.

So, now I have a little brick over here until someone locates a firmware for it, which I haven't yet.

I think it won't even go to download mode anymore ;)

Help? :D lol
[Android General] Demn:
Well, my T101 just showed up today, and I found this thread looking for a way to root it. Anything I can do to help?

Bearing in mind that this is my first android phone and I've had it for all of an hour, so I'm pretty damned new to things.
[Android General] NuttyBunny:
Wait and don't do anything else. As far as my tests went, it dies when you flash the cwm on it, perhaps the partitions are in different places.

I think someone would have to recompile zergRush as it's the one that may work on 2.3.5, but commenting out the 4.x verification. I didn't do this because I didn't want to download the compilers, etc, but as my phone died and your may if you do the same things as I did, I think the safest way will be to try this.

If someone has the compilers and everything and can help us with this, we'll be happy for you to jump in.

Demn, http://xdaforums.com/showthread.php?t=2165554 is the thread I followed. Don't do step 4, please, you're our only hope right now. ;)

Step 3 doesn't work btw, the phone doesn't have fastboot

Please, gather all the info you can, I can't anymore.

Use the device information, and maybe an app like antutu to see if there's more relevant info.

AGAIN, please, don't brick it, I want to fix mine :D
[Android General] Demn:
Well, I've tried that thread up to 1.2 where I get stuck as the USB driver doesn't seem to work for the phone at all, so no installing adb (haven't tried it yet without adb). I'm waiting for antutu to finish downloading at which point I'll run it, but I'm afraid I'm so new at android that I'm unlikely to be able to recognize what information is helpful. Might just take screenshots of any info screens and link them if that's OK.

I sure hope people figure out how to root it, because the phone is pretty nifty, and being able to clear out useless default apps would help so much. But (on mine at least) I'm stuck at 20 megs of free internal storage with a factory reset, and that's... just not a lot at all.
[Android General] NuttyBunny:
Well, those drivers are important. You have to install them in a 32-bit Windows (I used XP in a VirtualBox virtual machine)

Yeah, I didnt try the factory reset, silly me, I was stuck with 1 or 2 megs of free space which didn't make any sense at all.

I couldn't install anything in the internal memory, my tests went directly to the SD, but whatsapp refused to install (and I got the phone specifically for that app)

I hope someone help us with the zergRush binary. In the meantime I'll try to download it and compile it.
[Android General] Demn:
Ahh, didn't realize the drivers were 32 bit only. Well, I'll give that a go, then, though I'll probably just set up a separate machine for it (god bless spare parts.)

I had that happen (1 meg free tops) the first time when I had used google play, which installed a google play service thing, which then ate all my memory. After doing the reset I didn't touch google play at all and only installed things manually. That's let me manage to hold about 15 megs free out of the initial 20, which at least doesn't make the phone freak out with constant warnings.
