Hey there!

In the past few days I'm lurking all over the internet for info about "ZTE S7Q", I've managed to root it with tpsparky root and tried to flash some recoveries(cwm then twrp then generic cwm for 3.0.36+ kernel from crewrktablets), it seems that the recovery is flashed, but the screen is black. The menu is existent, even if not seen, when you press pw button right away - it reboots the device, if you play with the volume - it acts like there's a menu there and you can go back to the first option and reboot it(just like regular cwm), but all that happens when the screen is black. The weird part is that even before the root/recoveries flash, it went black screen on download mode/recovery mode. It came that way, but it seems that its not supposed to work that way.

Then I tried to flash a full system that seemed fit, with the rockchip batch tool. It failed and I soft bricked it. Now I stumbled upon this forum which seems to have a good community and a lot of helpful info that could be very usefull at the start of my journey.

Good news for me - I got 2 of these tabletswhile the second is untouched. My questions are:

1) Will this tool work for me, if I try to dump the img from the untouched tablet and batch it onto the softbricked one? How do I properly batch it?

2) What roms would you offer for these tablets? Is there any roms at all, for these weird chinese creatures? I like customization and xposed stuff on my phones, but this tablet seems rather weak and mostly oriented for media/web, so I'd be glad if there's anything stripped from features and fast, with moderate customization(basic tiles/navbar/pie customization).

The specs that I can get from the top of my head are:

  • rk3188 chipset,¬†1,4GHz Quad Cortex-A9
  • 1024x600, 160 dpi, 7" physical size
  • 1 gb ram
  • 8gb internal memory
  • 3.0.36+ kernel
  • rk30sdk(not sure what it is)
  • Came with modified and bloated 4.2.2 JB
  • pw button, +/- volume, 3.5mm jack and microUsb, 0.3mp front camera, 2mp back

I'm thankful for your time and sorry for this wall of text,

have a great day!

Hi, thank you for quick response.

I'm trying your utility, but it seems to be stuck for more than 5 minutes on root.jpgImage Enlarger

am I doing something wrong? 

P.S. If I root it the way I did with the first one, and then dump the firmware with this utility, it should be fine, right?

Try to root with Kingo-Root.

If you cannot get the shell (in the tool) then just do it on the tab. Load a terminal emulator from Play Store and type:

su
dmesg >/mnt/sdcard/dmesg.txt
logcat -d -v time >/mnt/sdcard/logcat.txt
cat proc/cmdline >/mnt/sdcard/cmdline.txt
cat proc/mtd > /mnt/sdcard/mtd.txt
dd if=/dev/mtd/mtd1 of=/sdcard/kernel.img bs=4096
dd if=/dev/mtd/mtd2 of=/sdcard/boot.img bs=4096
dd if=/dev/mtd/mtd3 of=/sdcard/recovery.img bs=4096
dd if=/dev/mtd/mtd8 of=/sdcard/system.img bs=4096

Did that, but problem once more.

Dumped everything except the system - the system goes up to 5.3GB(and then I'm out of space), so I tried to dump it to the external sd(7.3GB), but fat32 wont let me write more than 4GB(obviously).

That way or another, how the hell a system that should be around 1GB max, is writing img file over 5GB?? I'm fascinated.

What will be your advice in this situation?

Ok, dump looks good. Tab has RTL8188 wifi.

Kernel: http://crewrktablets.arctablet.com/?wpfb_dl=2509

Try this build: http://forum.xda-developers.com/showpost.php?p=47181523&postcount=900

Just change the kernel in folder rockdev/Images before flash.

Nothing newer than the 4.2? *avid kitkat lover*

Also I have 8GB internal storage, is there any fix for that? (Current NAND limits it to 4GB)

Your NAND is 8 GB. On your NAND are different partitions. Partition userdata (internal storage) is now 4 GB. Partition user (internal sdcard) should be around 2.5 GB. The remaining space (up to 8 GB) is used by system partitions.

You can check out our Omni build: http://crewrktablets.arctablet.com/?p=3555

Change the parameter file and your kernel before flash. In CWM install 160dpi fix.
