    PLT7033D Proscan tablet

    Hello all, so the other day I ordered myself this tablet here : http://www.proscanvideo.com/item.asp?itemnmbr=PLT7033D it was cheap and I like modding stuff so figured why not. I got it today and it is running OK, the first thing I did was root it which worked fine using a Rockchip root tool for RK2918 devices found on another forum. Next thing I did was try to get the CWM recovery working for RK2918 devices, that was a bad mistake...It installed correctly using this method from root shell
    1. extract flash_image and recovery.img from CWM.zip
    2. put flash_image and recovery.img into device, e.g.
      adb push flash_image /dev/
      adb push recovery.img /dev/
    3. enter root shell
    4. flash recovery.img into recovery partition with flash_image, e.g.
      chmod 755 /dev/flash_image
      /dev/flash_image recovery /dev/recovery.img
    5. you may need to disable install-recovery.sh which restores stock recovery on every boot
      chmod 644 /system/etc/install-recovery.sh
    Now I can't get into recovery by holding down the vol- key and power button or using the command "adb reboot recovery" It just turns off the tablet. So, I killed my Android recovery partition...anyway to get it back? Or flash a different one? Another thing, my device recognises I put a TF card into the tablet, but it doesn't notify me and when I go into the settings it has the mount button grayed out saying "please insert a storage for mounting" When I remove the card it says "Storage removed, insert a new one." I have tried 5 different cards so far. If I leave the TF card in the tablet it hangs on the Android loading screen, it never fully boots into Android. As soon as I remove the card, I'm back on Android...Possibly a kernel issue? My kernel is 3.0.36+ I also tried to use VPN software but Tun.ro is missing, so that's another issue I'm having. So, can anyone help me out here? I can get a dump of my ROM if needed, but I don't think that will help with my killed recovery issue.

    Also, another weird thing is. Proscan say's is a RK2926 cpu, even states it in build.prop but a few different identifiers have all told me it is a RK2928, so I wonder what one it truly is..? I also got the Google Play store to work, but not all apps are compatible, that's okay..I'm working on the build.prop fix! My main concerns right now are recovery and the SD card, and I would like to have VPN support as well.

    Thanks for the help!

          May the best will be you make a Dump of the Firmware that´s in your Tablet.
          When we got the Kernel and the Rest we can make a Custom Rom.
          If you need help Message me.

            I sincerely thank you for all the help!

              When you make a Rom Dump of the Tablet via ADB we well have all Images we need to make a
              Custom Rom with new Recovery.

              Try this Steps:
              For ADB

              I had to put the device ID 0x2207 into the adb_usb.ini file located in c:\users\myname\.android\adb_usb.ini. I had done this previously, but windows decided it knew better and would name the file adb_usb.ini.

              After that was straightened out, I had to go back into the driver (last night after my dinner neomode) C:\Android SDK Tools\extras\Google\usb_driver\android_winusb.inf and add the device hardware ids again. (Like an idiot I forgot I screwed with it a few days ago and changed a bunch of values that apparently made the adb-usb.ini not work function.)

              ;ematic GP007BL
              %SingleAdbInterface% = USB_Install, USB\VID_2207&PID_0010
              %CompositeAdbInterface% = USB_Install, USB\VID_2207&PID_0010&MI_01

              under [Google.NTx86] and [Google.NTamd64]

              Rom Dump:

              But in a SD Card to your Tablet:

              Then Type:

              su
              cat /proc/mtd
              then you see the Listing
              then make dd if=/proc/mtd/mtdblockxx of=/sdcard

              make it with Kernel System Boot Recovery ...

              After this connect Tablet to PC and Download the Dump, and please Upload it.

                When I try the command it says cannot open for read: Not a directory...Then I tried this here http://androtab.info/rockchip/devel/rkutils/ after copying over the rkdump and chmod I type /data/rkdump /dev/block/mtdblock1 /sdcard/kernel.img and it says : unknown image <00 00 00 00>

                So, what should I do now?

                  Okay, so I just downloaded a different version of rkdump82b.. Anyways, I tried the following command : /data/rkdump /dev/block/mtdblock1 /sdcard/kernel.img and got /data/rkdump /dev/block/mtdblock1 /sdcard/kernel.img
                  Android ROM dumper v0.82b
                  <c>2011 Sebastian404
                  Device :

                  Creating required files... done.
                  Opening mtd table... done.
                  Dumping kernel config... sh: cat: /proc/config.gz No such file or directory
                  done.
                  Dumping boot partition... done.
                  Dumping recovery partition... done.
                  Dumping system partition... done.
                  Creating Checksums... done.
                  Cleaning up... done.
                  All done.

                  So I think I got them all, but I'm worried about the kernel, did it dump it or not?

                  In my sdcard folder I have boot.img, checksum.md5, config.gz, recovery.img, systeminfo.gz and system.tar I noticed the config.gz is 0 bytes so don't believe the kernel got copied...What should I do now?

                    1.
                    cat /proc/mtd

                    2.
                    dd if=/dev/block/mtdblock1 of=/sdcard/kernel.img

                    Make this with

                      That worked! I got them all, even got the recovery.img it will take time for me to upload because my system.img is 512mb and I have slow upload but I'll post a link as soon as it's done! You will get boot.img, kernel.img, misc.img, recovery.img and system.img

                          Zipping it now, I was going to upload it to Dropbox but whatever you prefer I'll do, doesn't matter.

                            Hey Neo,

                              Okay, so tonight my tablet started getting real slow so I decided to re-flash it using the images I had previously created. I got the RKAndroidTool V1.35 and it found my device fine after I entered flash mode by holding Vol - and power mode for 3 sec, I then proceeded to check the loader and erase IDB, that went fine. I unchecked loader and checked misc.img, kernel.img, boot.img and system.img after a few mintes it said it had went OK. My tablet turned on and went to the Proscan blue starting screen as usual but it doesn't go past that. Any idea what to do now?
