Hi XDA,
so basically i bought a Velocity Cruz T301 recently and followed the known procedures for rooting, flashing ClockworkMod Recovery and custom rom (SJHill Rom v0.3).
before the full brick my device was at ClockworkMod 5 and rooted with SJHill Rom v0.3.
i installed CWM by flashing the zip in stock recovery, then succesfully rooted the device, finally wiped and flashed my custom rom
after major dissapointment in this tablets performance i decided i wanted to get rid of it.
So i downloaded the stock rom, wipe and flashed it onto the tablet...
the tablet turned off when it was finished (i think it was attempting to reboot) and never turned back on again...EVER! :good:
i cant even get to recovery
i tried flashing with adb and fastboot but the device is never even presents itselft to the computer.
i found out that you can boot the device into USB boot mode where you hold the "VOL -" (Volume Down) button and press the reset button and while connected to the computer (windows only) a "JZ4760 USB Boot Device" appears.
i did some googling and also found out that the T301 is based on similar tech to a bunch of tablets and they can all be modified by some software released by Ingenic called USBBootTool.exe
the tool is written in chinese and i cant decypher it all, though i found out how to use it based on its usage for other Ingenic based tablets
1.) you will need to disable driver signature verification (press F8 on boot of windows and toggle the setting, i hate rebooting too but it has to be done)
2.) boot your tablet into USB Boot Mode (hold down Vol - and press Reset button)
3.) install the driver for your device (included in the files below)
4.) with the tablet disconnected you would open the USBBootTool.exe
5.) select your tablet in the options and fill each box with the files needed to flash (files included below)
6.) reconnect the tablet while still in USB Boot Mode and the software will flash your device on detection
everything goes fine for me except when i get to the flashing part in the end.
when USBBootTool detects my tablet, it attempts to flash and gives me a stream of errors and never flashes my device.
i dont know what to do at this point. i have provided direct links to all the software im using and also links to where i got them.
any help would be appreciated, thank you to the XDA community in advance

I have the same situation. I have gone through every menu in the USB Boot tool and to no avail am I able to recover my T100.
gmick is redoing the software because the coding is set up wrong. Once he gets that figured out there should be a fool proof unbricking method that we can follow. He is posting information over on Slate Droid if you want to take a look.

*Cross Post from SlateDroid* (but I can't post the link because XDA won't allow it)
I found out why the USB boot isn't working. Well, more appropriately I know where it fails but not exactly "why".
The USB Boot tool works like this:
1) Send x00 command (Get CPU Info)
2) Device responds with "JZ4760V1"
3) Host sends two binaries, stage1 and stage2. Stage 1 sets up memory stuff, and Stage 2 sets up USB flashing functions.
4) Host checks that the binaries executed by issuing another x00 command (Which serves as an "Are you still there?" function)
5) If the response is good, the host will flash the images, if the response is bad, it will abort.
Our devices are failing at step 4. The linux usb boot tools (xburst-tools) fail in an identical fashion.
I know that the first stage binary transfers and executes fine because if it didn't the device would be limited to 16k. The second stage is 120K and is transferred successfully. Once the second stage "execute" command is sent, the device crashes.
The second stage is also unique to the CPU type. I've used all of the binaries for JZ4760 I could find on the net and when that failed I cross compiled my own binary from source and it still crashed.
At this point I highly doubt I'll ever be able to fix it, and this completely explains why no one could get any usb recovery tool to work while others using similar devices could. I guess our board is modified just enough for ingenic's stock binaries to fail. Without knowing what's changed (getting Velocity Micro's source) we're SOL.
I can open it up again and solder on the serial header but I'm betting it's going to give me some generic "couldn't execute" message that isn't going to help me. I'll probably do this anyway though because I've come this far so what's the loss.
wow, i learned alot from that post, seems like writing a usbboottool-like application that can send the commands but also log and possibly bypass security checks etc but that def would take sometime. thank you for your insight, seems youve come the closest to cracking the case, actually you found the fault, hopefully your methods can eventually bring about a fix

for my JZ4770 Earlier USB tool was flashing .img without any problem but for now it is saying "load cfg failed". "API downlaod failed' like dialogues and doesnt flash anything. Any idea? Thanks in advance!!
First restart your computer (actually restart it) then redownload the USB boot tool and save it in a completely new directory and use a different USB port
Sent from my Pokeball
Yes, I did

Yes, I tried with this suggestion. Rather I reinstalled xp and the tried again. But the dialogues are same. The history is like this. Was having ICS on JZ 4770. Formatted with usb tool and put JB updates. It was not sensing touch so reflashed another JB updates. Now the tab boots, it reaches to boot logo for around 12 seconds and restarts in stock recovery. While it is in booting stage it get detected by windows and adb also. In stock recovery mode it get detected by windows and in turn by adb also. If I tried to install updates through SD card it shows it had installed and reboots after completion. But again the same way it goes to boot logo and then back to stock JB recovery. It also boots in ingenic boot device mode and gets detected by USB burn tools. But when try to flash any of the ROM it gives the same dialogues "check cfg failed" "api download failed" "boot. fw failed" and cant flash anything.
Is there any tool which can be flashed or a script which can be used from SD card for completely formatting flash memory so that USB burn tool can flash required ROM?
can you flash the stock rom in recovery?

thanks man but I managed to boot the device. I used following USB BOOT TOOL for ingenic 4770 boards. The goodness with this tool, this is completely in English. You will know what you are doing. Even after opening the main window of the tool you can right click and then get another options(yes again in English). My problem with this device was bad blocks at 1024. In the options there is chance to force erase whole the nand partitions which I used and erased all the partitions thereby made all the partions available for flashing and readable by the tool. Then from File option selected stock rom files and flashed them. While flashing selected JZ4770 iNanad.ini file in manual configuration. This tool has really helped me to come out of the issue and will be useful for guys using JZ 4770 board.

Got USBBootTool.exe kind of working.
1. Download the following file from Ingenic.
ftp * ingenic * cn/3sw/01linux/tmp/jz4770-20110610.rar
2. Download Applocale from Microsoft.
www * microsoft * com/en-us/download/details.aspx?id=13209
3. Extract the jz4770-20110610.rar and find the folder. (Using 7zip should keep the UTF encoding in Chinese)
20110610\04burn\20110524_4770_Programmer
4. Copy the folder 20110524_4770_Programmer to location you want to use it in.
5. Install Microsoft Applocale (Just in case, I don't think it is required)
Now Start Applocale and create a shortcut to USBbootTool.exe inside 20110524_4770_Programmer
中文(简体) is simplified Chinese option and should let you view the GUI correctly.
6. Now with the Applocale Shortcut created for USBbootTool.exe you can start the application with correct fonts.
Now this is where is breaks down.
TABLET-8 NAND FINAL BSP(S3 TEST) will allow you to read from it and write to it, but the CFG is off.
\tool_cfg\tablet-8-nand-final.ini is the configuration for it.
DO NOT CONNECT THE DEVICE WITH ANY OPTIONS CHECKED OR LOAD ANY FILES.
See Attached Images.
Next to the Read button is some Boot Option menu. I am not fulling aware of what this does.
What I need is a someone to help me fix/correct the ini/cfg files in
\20110524_4770_Programmer\tool_cfg\.ini
\20110524_4770_Programmer\4760\
to correctly match the files of the NAND.
Also if anyone has a copy (dd to img) or (cat to img) of the block devices.
That would help a ton.
# cat /proc/partitions
# cat /proc/mtd
I would also love another T10x Tablet for cheap.
I want to start building things like new bootloader, kernel, system image,
performance libraries to take full use of the Ingenic JZ4760 (www * ingenic * cn/product.aspx?CID=11)
I also bring Christmas gifts
2 APKS. You can place them in /system/app or /data/app.
Google Play will crash now and again, but it will load and work. (Vending.apk)
Secondly I bring the gift of performance increase, just by a slight bit.
edit the line of the heapsize in /system/build.prop dalvik.vm.heapsize=96m
Remember to make sure the permissions are set back to 666 or 644.
Original Vending.Apk before updates came from here: (Incase you are paranoid)
code * google * com/p/ics-nexus-s-4g/source/browse/trunk/system/app/Vending.apk?spec=svn20&r=18

Which block images do you want?
...also is there a way to rip the stock images off the jz4760 in the t301.
Such as:
Can i usethe ingenic uboot tool?
Anybody find the jtag pins?
Is the 4 pin conn next 2 the batt for serial?
.......i guess ill try to take a look this weekend
Ics would be really nice, but probably slower than stock..... especially with the limited ram
I unpacked the stock rom. I also unpacked an ics rom for a jz4770, and repo sync'd the aosp and mips 3.0.8 android kernel.
I'm still trying to figure out specs for the processor though. I know that its mips32 - el- fp- r1, but i cannot figur out the dsp version ... if it has one?

I've seen some RK3066 tablets mentioned, but I think it's time to publish some software and assist those who can and are curious to develop.
First of all, this is the same old Teclast P85 with an Allwinner A10 chip, but this time it hosts a more powerful RK3066 dual core chip, with "quad core" Mali 400 (from what I understand it uses two physical cores and two threaded ones). Alongside it there is 1 GB of RAM, internal SD card of 16 GB, 1024x768, 8 inches...
What I bring here to the table is both a ROM from Teclast, the last working one to my knowledge (1.17) and a /system pull, in the hope that someone wants to pick them up.
If someone picks this and wants to poke about, I'll be glad to test and report.

Hi Logseman, are there any way to root this tablet ?
Yes, you can use ZhuoDaShi with these instructions:
http://tabletrepublic.com/forum/teclast-a10-dual-core/how-root-teclast-a10-dual-core-2491.html
Christian Troy has been able to bring CWM to RK3066 devices. I'm laying a How-To here, but I don't guarantee that CWM will work flawlessly or as intended. I just used these steps to install it on my tablet, and they worked,
You need the update.img with the ROM you're using in your tablet, Wendal's tools to unpack RK images, and Christian Troy's CWM build.
1) Unzip the file which contains Wendal's tools.
2) Rename your update.img to wendal.img and move it to the folder where Wendal's tools are.
3) Run Runme.bat
4) Go to the Temp folder and copy the parameter file you have obtained.
5) Unzip the file which contains CWM.
6) Enter the folder which says "rom" and paste the parameter file from your tablet, replacing the one that is there.
7) Run the RKAndroidTool app in the CWM folder.
8) Connect your tablet in Flashmode: switch it off, and connect it while you hold the VOL+ button. If Windows doesn't find the drivers, they're packaged in the "Drivers" folder of the CWM file.
9) Now the RKAndroidTool should recognize your tablet. Click on "Flash ROM".
10) The tablet will restart in CWM after the flashing. Just poke around for a bit, and if everything's all right, restart the tablet,
Thanks go, of course, to Christian Troy and Wendal. If you can, donate to those guys, they're amazing!

- use these file (make backup before!!!) with this guide and you are done
Update 12.04.2013: Different Sound improvements
People who have problems with sound try this link from Zopo-Forum
or from Patchworkoftips
Update 11.04.2013: Data Resize partition to 2.74GB Detailed description from here
1. We backup with recovery.
2. Unloaded and 2.74GB decompressed data (Thx to spanish friends! ).
3. SP Open Flashtool and as we have done before installing the recovery in scatter-loading MT6589_Android_scatter_emmc.txt select the file in the folder where we unzipped 2.74GB Data
4. We ensure that only EBR1 and EBR2 are marked.
5. We Give to Download, accept the prompt, connect via USB the phone off the PC. As with the recovery if the process fails, disconnect the cable, remove and put the battery and repeat this step.
6. If all goes well, will back the green circle. Disconnect the phone from the PC.
7. Now we go back to recovery (Turn on the phone by holding the power key + volume +).
8. In the recovery do wipe data / factory reset.
9. Optionally if you want to restore the data and installed applications we advance restore, choose the backup you made in step 1, and finally we give to Restore data.
10. Reboot from recovery. In this first boot after repartitioning we may see a notification saying the phone storage is damaged, then click in it. It will show a dialog box asking if you want to format the SD card, does not refer to the External SD but the phone's internal memory, so we do not fear clicking on Format. After doing the latter, voila, you have the Data partition (where apps are installed) extended to 2.74GB
Update 08.04.2013: 3G improvement
if phone is already root
Install from market the mobileuncle tools.
-> enter engineer mode (MTK).

I've got a quad core 6589 version, so far cannot find a way to root it..
And it's NetworkLocation.apk is missing, i tried a couple of NetworkLocation.apk from JellyBean gapps zip files, no one seems to work, either not installable, crash on boot or not working.
3G connection seems to be dodgy, H/H+ is shown on the top bar but data is not coming down normally, during 1 minute, only less than 100k data come down and not able to load even 1 page...
Anyone has the same problem?

star b943 (mtk6589 b94m)
could someone translate recovery menu from Chinese Language
Yes the baseband or antennas seems to be crap.
Start download and remove your hands from the device or take it only with two fingers on the upper side, then my downlads finish and downloads show normal values. Speedtest with upload is seems to be fine,...
If someone needs root or cwm write me pm, or give me public upload location I´m not so experienced with this,...
Best regards
Thanks for the advice

The MT6589 is really good stuff, for me its my personal Favorite , but I would prefer smaller devices with 4-4,7" max screensize.
5,5" and higher does not really fit in any shirt pocket. If I ever have to carry a bag for my phone I would prefer a tablet with much better screens and battery life.
So i´m looking forward to Jiayu G4, G5, UMI X1S, or something similar screensize

5. using the SPFTools load in directory 2. Scatterdatei -> load and Recovery.img, boot.img and flash (press download and then return battery back)
6. Disconnect the data cable after green OK
7. When switching power and Vol + hold when the Green Man comes release Power and Vol + hold on.
8. In CWM now either only make complete backup, or install zip from SDcard install the superuser zip ...
9. skip step 7 +8 and install superuser using the MTKdroidtools and make backup (but it takes a relatively long time)
10. You can now delete with MTK Droidtool some China-apps."

That's great!!!!
Thanks, it worked!
Now I still have two problems:
- amazon app-shop doesn't start (it remains black with amazon logo)
- doesn't vibrate on call in vibration mode
does someone else have the same problems?
Thanks

vibration problem was a wrong setting by my side... still have problems with amazon app-shop (very strange, I've it installed on many devices and different versions of android, jelly bean included)

Thanks for the alert.
I've got a quad core 6589 version, so far cannot find a way to root it..
And it's NetworkLocation.apk is missing, i tried a couple of NetworkLocation.apk from JellyBean gapps zip files, no one seems to work, either not installable, crash on boot or not working.
3G connection seems to be dodgy, H/H+ is shown on the top bar but data is not coming down normally, during 1 minute, only less than 100k data come down and not able to load even 1 page...
Anyone has the same problem?

The MTK chipsets have always been weak on data connection starting from the MTK6573. It's so bad that connection can be lost while my Samsung right beside it has a good connection.
Anybody knows what is wrong with this China made phones?

I managed to root. Thanks for the help guys (sarcasm).......The files that "cmoegele" posted worked except for the usb driver files. I had to use PdAnet for connection. I'll be watching to see what other members find on the camera focus and poor data comms.
Thank You
Data upload is stable, and downlad has good values for a while, but slows down from time to time. So I think the device is not doing completly wrong. There needs to be still some finetuning in Baseband and Rom like man other devices always need.
The performance and quality is really good, even +2 days Batter lifetime is a good value for this powerful device.
I´m waiting for new Roms

Hi fmehrtens, may I know the RAM and ROM capacity of your phone model? I am wondering if 8GB ROM and 1GB RAM model can be rooted using same method, thanks.
Spec says 8GB ROM and 1GB RAM, however AnTuTu shows only 1GB ROM and 1GB RAM. Am I missing anything here?
Hello,
I've ordered this new phone Star One B943 Quad core, and i want to thank u for the rooting method ^^
I'm searching for the ROM stock, does anyone have the idea where i can find it ?
And i found that the Miz Z1 is the same phone, but with Android 4.2.1 installed. Do u think it's possible to upgrade the Star OS version with the Miz Z1 firmware ?

It is a 4G ROM and 1G RAM. Just FYI, the first time I tried to root it did not root, I had to try it a couple of times, and then I also loaded the ZIP file on the ROM memory along with the SD card. It worked that time. Not sure if that's what helped or not. The phone is a really nice phone ecpecially after rooting. I am also having trouble with Amazon App store app, Netflix playing too slow and the camera focus.
Good Luck and Thanks!

I have got a Copy of the origin Rom done with SPFTools. If it is needed. You also can use the Scatterfile from the zip-file.
Do you have a link for the 4.2.1 Miz Z1 firmware ? Perhaps its a fake,...
Otherwise I will flash it to our device except the Preloader, so if it fails I could go back to stock.

May I know the country you using the phone in? I have very bad experience with MTK chipsets with regards to data transfer. Other phones e.g. Samsung, LG do not give me this problem.
How to improve the data performance?
Hello every one i have an issue here, i got a chinese device a samsung galaxy s(it says its an S4 but i think it is an S3)its a 1Ghz dual core processor if im not wrong(firmware use to say MT6575_S01)
it had loaded apparently a wrong rom, the device wasnt loading OS and restore wasnt working, i tryed to flash a new rom with Android Flash Tools, and the device got bricked, i am able to connected to the computer, the device does not turn on, does not charge, but the PC is able to detected as a MTK USB Port Com.
i found that trying to load different rom with the same tool was not possible cause it gives me an error just before start downloading the info(this is because the device lost connection on the device manager) so it doesnt charge anything.
as i already mention i am able to install drivers, but all of them goes like a Com Port, i used USBDeview and i am able to see the old MTK65xx usb drivers but the direction for that port its not valid(at least it does not recognize the device as a USB directly)
i was wondering if any one can help me with this, i need to know if there is any way to prevent windows from disconecting this device or if there is any way to make the device go on away, if i can do that i am sure i can load the image to it.
BTW i tryed a few roms and some of them tell me they cant complete the process cause not enough space, cause it looks like they are for another device.
my system and device specs (device as far as i can get)
device :
CPU MTK6575
Model: M-9162 cnc moviles (could not find any website related to them)
as far as i know the processor is a 1.2 Ghz dual core
512 RAM
dual SIM
8 MP cam (back)
as far as i know it could be 2MP or 1.3 MP on front
Front camera and sensors are located on the left side(not on the rigth side like most of galaxy S· and S$ even clones)
use battery
model : 303
li-ion 2200mAh(it says samsung)
PC SPECS :
Windows 7 64 bits OS
dual core 2.4Ghx processor
4G on ram.
Please help me with this and i will love you all forever
PD : i belive that the model is a replica of I9200 but not sure .
THANKS.
mk6575 bricked device
as an update i manage it to flash a nand rom apparently for an s3 mt6575 NAND memory, but i am not sure if it is the right one, cause memory on smarth phone android dlashing tool, shows flashing 2g of ram and this is my memory test results :

wasn't necessary thinking Linux ubuntu only...but if you made bootloader look for a system on a sd card android,linux,windows,exc...you could have a dual boot system....this would be awesome it would make it easier to mod system files and experiment with different os and have the ability to pop out the sd card and be back to stock config if you didn't want to boot off sd card make an sd card to redirect boot loader back to internal system...or if bootloader can't find a os on sd make it default back to internal system. ..I think something like this would be one of the best things that could help speed up development and allow roms that were built for different partition sizes and systems become more Universal .

Can you help us root this firmware ? https://drive.google.com/drive/folders/0Bz8umNL1qrsoLVh5cHVSdmVQOWc
Yes I have seen that that's why I wanted someone to use titanium backup on there unit and do a full backup or nandroid. Also .titanium I believe will generate a update.zip file that could be flashed...once this is done you could just do a standard restore with a titanium or nandroid backup. ....I have reached out to a few people about a multirom boot setup hopefully we can get that to work and boot and flash to sd cards....
Also remember some units are 16gb and others are 32gb so the partition tables will be different. .but that's nothing that can't mod to be fixed...another reason multirom flash to sd card would make life easier
this can be the answer if can this be done with our head unit.... http://www.xda-developers.com/install-use-multirom-xdatv/

:fingers-crossed: can install or update MultiROM, it's recovery and kernels. It can also install Ubuntu Touch system-image based builds into MultiROM as a secondary ROM.
MultiROM is one-of-a-kind multi-boot mod for Android devices. It can boot any Android ROM as well as other systems like Ubuntu Touch. Besides booting from device's internal memory, MultiROM can boot from USB drive connected to the device via OTG cable. The main part of MultiROM is a boot manager, which appears every time your device starts and lets you choose ROM to boot. You can see how it looks on the left image below and in gallery. ROMs are installed and managed via modified TWRP recovery. You can use standard ZIP files to install secondary Android ROMs, daily prebuilt image files to install Ubuntu Touch and MultiROM even has its own installer system, which can be used to ship other Linux-based systems.
.Here's the deal... if we could dual boot another android os for head unit let just say rom from joying or other brand/manufacturer you could test rom see what works and what doesnt , modify rom ,extract apps from rom and if rom was better you could make rom you primary boot ..(i also believe we could add or mod the mcu part back in the rom).:fingers-crossed:... and you would be able to test this all with out erasing you stock configuration or stock rom ....you would be able to test and develop new updates as they come out.. you could test with out erasing or wiping your system.. you could run Ubuntu ,Ubuntu touch or other more pc based os and still have the ability to reboot and be back in radio os android mode....and I think there is a fun factor here with experimenting and adding more function to the head unit

there are now at lease two types of intel units out there ones based off mtcd and non mtc ones on a totally new board...the firmware should be similar as for there both built for intel x86....developments that help one should be able to be applied to the other...the biggest thing that i think that would help both platforms would be the ability to dual boot these models so you could run experimental os fw os a sd card and still have the ability to go back to stock configuration simply by removing the sd card with the os on it or just telling the bootloader to boot the stock system img....thist is where i think we need to focus and develop.....
Joying JY-UL135N2 2G RAM 32G (Intel Sofia3g and STM8S207C8T6 MCU)
My unit:
Joying JY-UL135N2 2G RAM 32G (Intel Sofia3g, STM8S207C8T6 MCU, TDA7388)
This is not MTCD based unit. My MCU chip is STM8S207C8T6
I got following MCU Version: 2016-08-29 15:46:12 JY_(NOR)__90_C9_7706_5009_CAN(GX)_Newlap.
Purchased from here: Joying on Aliexpress
Photos of the unit outside
Photos of the unit inside
Original (non-modified) boot.img and recovery.img
Note that I have not verified the content, as I do not have sufficient knowledge. I was guided by gurus to extract these partitions from the unit just in case someone really needs them. I have not tested files personally.

Root instructions (credit to Spider84 for providing instructions and modifying boot.img):
https://drive.google.com/open?id=0B2DmzEjJljx3OXlQM2RFbWp4UWc
Method 1 (didn't work for me, as I could not figure out how to enter revovery):
1) Copy to USB thumb Drive
2) install from recovery
Method 2 (didn't work for me either):
1) Copy to USB thumb Drive
2) Go to Settings -> about device -> system updates
3) System should ask if you want to install update
Method 3 (worked for me):
1) you need to know how to connect and use adb. I connected using head IP address from laptop connected to the same wifi router. I did not use any additional apps or software (other than adb from android sdk). Hint: https://developer.android.com/studio/command-line/adb.html
2) extract su.img, SuperSu.apk and boot.img form the update.zip, place it on USB drive
3) use following commands:
cd /mnt/usb_storage3 (change path according to your USB drive)
cp su.img /data/su.img
cp SuperSu.apk /data/SuperSu.apk
dd if=boot.img of=/dev/block/mmcblk0p9
4) reboot
THIS IS A GREAT START THANK YOU
a system ROM zip for seller would be useful ...
.also please use apk extractor (updated instructions and link in first post)and back up all apps and system apps and upload that would be helpful.....
we need a full backup copy of total system try to make with nandroid backup or titanium backup you would need root to do this ..
I just got what you've been waiting for, the Joying upgrade file dated 10-31. I have the JY-UL135N2, just like StingerRUS above. I e-mailed Joying about the update shown in Boy ka's youtube, and they sent it to me here: https://mega.nz/#!iUECzLDB!oxXcP9Xa_jOeH3NTWoqwlPNzfYbeOHcJ_hP1NhvHCQs
I kept trying to ask them to show me how to root, as stated on their website root is supported, but they kept saying it's not recommended and would "make chaos for the unit". I tried Kingoroot, but that failed. Hope this file helps.
