Hi!, I am looking for the firmware to unbrick my tablet LT1002B, 10.1",CPU RK3066, WIFI5931, BT6622, board DA11G_V11_0415. The manufacturer is Letine but this tablet is sold under other brands like Flytouch, Superpad, Esperanza, Kingpad, Ippo, etc.

My tablet had a problem in booting (stuck in start page) so I tried to flash firmware but it for other tablet model. Now it is bricked so I need the correct firmware to make it work again. One thing that is very strange: I tried flashing my tablet with firmware of mini pc MK802IIISB (Rikomagic) and the tablet worked all ok except screen, touchscreen and wifi/bluetooth (image from hdmi port to tv ok). I tried other firmwares but no help.

I would be very grateful if someone could help me and tell me where can I find it.
Thanks in advance,
Regards!

Maybe the firmware/kernel for Flytouch 9 will work: http://www.flytouch-tablet.at/board75-flytouch-9-dualcore/board89-firmware-rom/2149-flytouch-9-dualcore-rk3066-cpu-rom-firmware/?s=4c7de78bd2a77ee45efb046c626708423a487760#post11001

Hi Oma,

Thanks for your fast reply! There are various firmwares for Flytouch 9: I tried from other site one  firmware that is specified for Flytouch 9, wifi8188 and other firmware for Flytouch 9, wifi8723 but both firmwares did not work and even the display was white. In the link you sent me (I am  also a member of flytouch-tablet.at site) I can see many other firmwares for Flytouch 9:

Original Firmware Android 4.1.1 - 20121112 : Download-DB:211

Original Firmware Android 4.1.1 - 20121128 : Download-DB:214

Original Firmware Android 4.1.1 - 20121216 : Download-DB:224 , but there is no specification of wifi/bt chipset. Do you know if there is a Flytouch 9 firmware version for wifi5931 and bt6622 chipsets?

Regards,

lgarrido.

No, I don't know. The idea is just to find a working kernel from a similar board. You need to test.

A white display indicates that the screen driver doesn't work.

MTK5931 wifi in combination witk MTK6622 Bluetooth is far away from mainstream. However, wifi/BT driver is in the build not in the kernel.

Here is an other firmware for the DA11G board: http://ublaze.ru/forum/topic1559.html

Hi Oma,

I have been testing all the firmwares from site "flytouch-tablet´s" but none of them worked on my tablet because in all cases the screen was white and in some cases firmwares showed the start screen through HDMI port but did not complete the boot process Just in one case the boot process was completed but seemed unstable (auto restart).

According to my search, I found three different brands of the same tablet model. My tablet is LT1002B, RK3066, WIFI5931, BT6622, board DA11G_V11_0415 and there are other models like Esperanza ETB103, IPPO V10 and Tabtronics FT9 that have the same board DA11G_V11_0415. 

Then I tried to contact the respective tablet vendors/manufacturers and just receive reply from Esperanza customer service who sent me the firmware but in 5 partitioned files, not a whole single image file. I flashed the tablet with these 5 partition files and the tablet screen worked but got stucked in boot screen (esperanza logo).

I tried other firmware from Archos Arnova97 G4 9" tablet and it had the same result as Esperanza firmware: the arnova logo showed in the start screen but there was no completion of boot process.

Any suggestions?

Thanks in advance for you kind help.

Best regards,

lgarrido.

Hi Oma,

At this moment I have tested many firmwares and just few of them nearly worked. 

Esperanza ETB103 and Arnova 97G4  firmwares show the word Esperanza or ARNOVA in the start screen but no boot process is completed. I could not enter the recovery mode (vol+ plus power buttons) to wipe data/factory reset (According to Esperanza Service instructions, after flashing the firmware, need to wipe data by entering in recovery mode).

For Esperanza tablet ETB103 firmware I have attached compressed files, also with tools.

For Arnova 97G4, here is the manufacturer link: http://arnovatech.com/support/updates_fwm.html?country=us&lang=en

Mini pc Rikomagic MK802IIIS worked almost ok, the boot process was completed, I could connect a mouse and manage apks, enter configuration (image output through hdmi port to tv ok) but no image in the tablet screen (just all white) and no wifi nor bt connection.

What do you recommend on how to proceed?

Thanks and regards,

lgarrido.

Change the attached config file (unzip first) in folder Flasher_tool and try again. Execute EraseIDB befor Flash Rom.

Hi Oma,

I tried flashing the firmware (erasing idb first) with the new config file on folder Flasher_tool but there is no change. The start screen shows freezed and I still can`t enter into recovery mode. While flashing the tablet I could see that the new config file of the Flasher Tool made one of the partitions files (backup.img) not to appear for selection.

Could something be wrong in recovery.img file?

Regards,

lgarrido.

Hi Oma,

I would like to ask you if it is possible to adapt the firmware of minipc mk802iiis (which works on my tablet) since at this stage of my search for a firmware it seems one of the two options I have (the other option is the firmware for tablet Esperanza ETB103).

Thanks in advance.

Best regards,

Hi laurentiufocsani,

I will see it later and tell you the part number of missing smd.

By the way, can you send me the firmware for this tablet? I could not find it anywhere. 

Thanks,
