Try to turn it back on within 30 seconds after it went to sleep. If it wakes up then you've got the same error as skippie's.

We didn't find a solution for that until now.

I rebooted in recovery mode to flash the tweak to increase speaker volume. I downloaded the two zip (the modified and original one) to the download folder in the sdcard0 (not extSDcard)

When I try to install the zip in TWRP I select "Install" but I don't find any folder in the "sda1" folder. Is empty. If I click the button bellow "Select Zip to install" I only see

Micro SDcard (2950MB)  (selected)
OTG USB Stick (0MB)   (I can't sellect obiously because I don't have it connected)

Is this normal?

Go to the mount menu and mount your internal memory.

Or just put the zips on the sdcard or otg usb.

The problem is that the option to mount the internal memory don't exist, only extSDcard and OTG USB stick

 

I have modified the file manually

There are several occasions where you might need a bootable SDCard for your tab.

This is a guide howto create one.

The bootable card itself can not harm or brick your tab if you boot it.

But what you put on the data area of that card indeed CAN brick your tab or heal it from a brick.

So - be careful and always be aware of what you are doing!

The procedures were tested on Windows7 Professional x64 german edition.

Unfortunately I can't help the MAC users - lean back and eat an apple for your health...

Last Warning!

Wrong usage of the tools and scripts in this thread can ruin your tab!

First download and unpack to a folder on your PC.

And before all the noobs ask again and again - the answer to all the following questions is NO! ;)

  • Is this a new ROM for my tab?
  • Why can't I flash this using TWRP?
  • Could you create a flashable package for me?
  • Does BootableSD.img boot Linux on my tab?
  • Will this unbrick my V989?
After unpacking you will see four new files:

  • SDcardMaker_eng.exeTool to create a bootable SDCard.
  • u-boot.binBootloader extracted from Rozak's V2.0.1 4GB ROM to be used with SDcardMaker_eng.exe.
  • Win32DiskImager-0.9.5-install.exeInstaller for Win32DiskImager to restore/create images of SDCards (bootable or not).
  • BootableSD.imgThis is an image of a bootable 16GB SDCard. Use it with Win32DiskImager.
Now there are two ways to create a bootable SDCard:

  • The easy, correct and quick way.
  • The long way.
Let's take a look at the easy way:

  • Insert your SDCard in the cardreader attached to your PC. The SDCards size MUST NOT EXCEED 32GB as FAT32 can only use up to 32GB!
  • Check if you want to save data beeing stored on that SDCard as it will be cleaned by the following tasks!
  • Right-mouse-click to SDcardMaker_eng.exe and choose "run as Administrator".
  • Select the drive of your SDCard. Be sure to select the correct one!
  • Activate the checkbox "Repartition and format (to fat32)".
  • Select the bin file: --> Open --> Choose u-boot.bin you unpacked before.

    Should look like this now:

    attachicon.gifSDCardMaker.JPG

  • Click to "Make a boot card".

    The tool partitions the SDCard, writes the bootloader and opens the Windows format tool.

    Let it format the card. You may choose your own volume label here.

  • Close the Windows format tool.
  • OK --> Close SDcardMaker_eng.exe
Your SDCard now IS bootable even if it appears to be blank if you open it in your explorer.

And it will stay bootable no matter if you copy files to it or delete the files after use.

You only may not reformat or repartition it! This would clear the bootsector!

----------------------------------------------------------------------------------------------------------------

Now let's take a look at the long way for the people that do not trust the quick way or are unsure if they succeeded running SDcardMaker_eng.exe:

I only tested this with my 16GB SDCard. I do not know if this will work using a 8GB card or less.

Even your 16GB could be a few bytes bigger or smaller and could break the process.

Please report your results using cards of different sizes and manufacturers...

  • Insert your SDCard in the cardreader attached to your PC. The SDCards size MUST NOT EXCEED 32GB as FAT32 can only use up to 32GB!
  • Check if you want to save data beeing stored on that SDCard as it will be cleaned by the following tasks!
  • Run the Installer Win32DiskImager-0.9.5-install.exe. Grant it access to your system.
  • After the installation is finished you should have a new Desktop icon named "Win32DiskImager".
  • Open Explorer.
  • Right click to the drive holding your SDCard and select properties.
  • Select "Tools" and run the Error-checking --> Check now...

    This releases the drive locking to enable Win32DiskImager and get access to the drive.

  • Close the drive's properties.
  • Right-mouse-click to Win32DiskImager icon and choose "run as Administrator".
  • Under "Device" select your SDCard's drive.
  • Under "Image File" select the unpacked file BootableSD.img

    Should look like this now:

    attachicon.gifDiskImager.JPG

  • Click to "Write" and be patient. As 16GB will be written to your SDCard this takes a while...
  • Wait until it's finished, confirm the finished-message and close Win32DiskImager.
Your SDCard now IS bootable even if it appears to be blank if you open it in your explorer.

And it will stay bootable no matter if you copy files to it or delete the files after use.

You only may not reformat or repartition it! This would clear the bootsector!

----------------------------------------------------------------------------------------------------------------

Now - what can we do with that card?

To be continued in the next post...

-----------------------------------------------------------------------------------------------------------------

I have 4gb mSD and new ONDA V975m 1.1.0 V4 stock. You think that your procedure how to create a bootable mSD is ok for my situation? I have to use the U-Boot.fin file you suggest in the post? I want to load the last Rozak's TWRP rom and i wanna be sure to do everything in the right way. If i can start the TWRP without flashing what i have to do to lo ad the last Rozak's ROM? I have to copy it on the sane mSD? Sorry if i bother you with a lot of questions bit i'm a little bit confused

Maybe i can update from 1.1.0 V4 stock to 2.0.1 stock with clean install and then i can create a bootable mSD with the u-boot.bin of the 2.0.1.Or i have to do it with a custom rom?

What can we do with that card now?

Part1 - boot a recovery TWRP without flasing it

----------------------------------------------------------------------------

For all tabs V1, V3, V4 running stock ROM or rozak all versions:

  • Download V2 TWRP
  • Open the archive.
  • Within the archive navigate to system/etc and extract the file "recovery-scibee-v2-twrp2.7.img"
  • Rename "recovery-scibee-v2-twrp2.7.img" to recovery.img

----------------------------------------------------------------------------

For all tabs V1, V3, V4 running stane1983 ROM all versions:

  • Download V3 TWRP
  • Open the archive.
  • Within the archive navigate to system/etc and extract the file "recovery-scibee-v3-twrp2.8.img"
  • Rename "recovery-scibee-v3-twrp2.8.img" to recovery.img

----------------------------------------------------------------------------

After you successfully extracted and renamed the appropriate TWRP recovery.img copy the file to the bootable SDCard you created in the first step.

This is the only file needed to run TWRP on your tab!

DO NOT COPY "aml_autoscript" or "factory_update_param.aml" to the card! Both files could wipe or clear your NAND!

You may copy flashable zips to the card if you want to install them of course.

 

You can now use this card to:

  • Backup your tab
  • Restore your tab
  • Install flashable zips
  • Test if you have that new touch controller in your V4 which is currently not supported by TWRP.

    Boot the card to TWRP and see if the touch reacts to your finger tips. If not - you are affected and you should not install any TWRP until further notice!

    In case do not use stane1983's TWRP installer as he in fact uses my TWRP (of course I agreed to that).

  • skippies tab MUST use this card to successfully boot to stane1983's ROM because he has a hardware problem and I found no way to repair that until now.

 

Hi Scibee, if i start in TWRP without flashing it , in which way i can install the latest Rozak rom "ONDA_V975m_V3V4_v2.0.1_rozak-2014118-TWRP"? I have to copy it on the same mSD card or i have to put it in a USB stick connected to the OTG adapter?

Didn't try myself but it should work if you copy the zip file to the sdcard.

Do not unpack the zip. Just copy it.

I don't own a MAC but I heard of people using a XP virtual machine on their MAC. This way you should be able to run all the Windows tools.

I tried to re-flash the stane Rom using USB_Burning_tool and in this occasion the soft has been able to erase the bootloader and the flash operation is finished without problems.

 

I'm still stuck in a loop too, can you please tell me what did you do (which files to download, what do I click in Usb burning etc)?

 

Edit: Ah, found it

These files can only be found in non-TWRP versions.

You need the ones that are capable of changing the application space.

Only these ROMs recreate the partitions and reinstall the bootloader.

You can't directly go from rozak to stane1983's Lollipop because the NAND partitions need to be redefined first. First install Stane1983's Kitkat ROM via USB Burning tool. Procedure is in the opening post of "Onda V975m ROM by Stane1983". After that you can update this to Lollipop.

Hi,

 

Thank you for your answer.

 

Stane1983 description not too clear to me, could you help?

I've download onda_v975m_0.9.2-usb.img and when I want to download Amlogic_USB_Burning_Tool.zip 2.0.4, setup_v2.0.4_x86.exe. downloaded.

Is it OK, or the link is wrong?

 

Update, the link is ok..

 

Am I right, that I don't need SD card for it (only just for copy the zip out from the img)?

 

When I start USB Burning Tool, it recognise the tablet with pressing Vol+ and Power, and when I start with the image, it stops after a few second with:

 

 --- [0x30101002]UBOOT/Low power/Send command/USB Control setup error --- message.

Does it mean, that I have to charge the tablet?

When I plug the wallcharger to it, screen blacklight blinking

Hy!

 

I follow the instrucion, but the tab don't boot from the sd card. It uses the default recovery, not the twrp recovery. It is only a 2gb card, so the other boot version is not option for me. Any solution?

Hi,

 

When you run the 3 script, did you remove the SD card? 'cause it isn't need for the flashing and the restart.
