hello.

i tried to make custom rom and something went wrong and i put it to my tablet.

then i'm unable to boot and cant enter to flashmode.

i have black screen as same when i put custom rom into my tablet.

the problem:

i power my tablet off(by holding power button about 10 secs) the i open RKAndroidToolv1.37 it says "No Found..." then i hold power button and volume(+)  while holding them i plug usb cable then RKAndroidTool says like half a second "found RKAndroid ..." and then it goes back "No Found ...".

and thats the problem this tablet cant enter/stay in flashmode.

Looks like there is no kernel on the NAND to start.

 

You need to bring the tab in Mask-Rom mode: http://www.youtube.com/watch?feature=player_detailpage&v=wMl6IbYBLtU

I don't know your tab. The video is for a similar RK3188 tab called Chuwi V88.

Pls find below some written instructiuons for the V88.

Together with the Video it should be possible for you to recover your tab. Good luck!

Part 1: Open v88 and short out NAND module
1. Unplug usb and power charger from v88.
2. Perform a "Deep Power Off" by pressing the Power button for at least 20 secs
3. Start up both RKBatchTool and RKAndroidTool using admin privileges
4. Open v88 casing
5. Power on v88
6. Connect v88 to PC using USB
7. Locate pins 8 & 9 on the #1 NAND module and short them out using a small pin, paperclip or small screwdriver. If shorting out pins 8 & 9 don't work, try shorting out pins 7 & 8
8. By shorting out the NAND module, you have put your tablet in "Mask ROM Mode." The RKAndroidTool should now indicate your tablet is recognized by showing the following message: "Found RKAndroid MaskRom Rock Usb"

Part 2: Erase corrupt NAND memory
1. Click on the #1 box within RKAndroidTool (the Loader box)
2. Click on "EraseIDB"
3. Wait for the RKAndroidTool to indicate the EraseIDB was successful
4. You can now close out RKAndroidTool

Part 3: Reflash firmware/ROM onto v88
1. Load firmware/ROM into RKBatchTool
2. RKBatchTool should have it's #1 Box highlighted in blue
3. Click Flash ROM
4. Done

The following users say thank you to Oma7144 for this useful post:

hi again.

now i have littlebit difference broblem.

when i trying to enter normally to flash mode always in rk patch tool connected device turns blue and it enters after 7 secconds while holding power button and volume up(+) and i dont even need to hold volume up(+) it enters automaticly when usb cabel is connected.

thats too wierd.

 

oky when its in flashmode then i can change my rom but no matter what i do restore or upgrade always i see error "Prepare IDB Fail".

with "RKAndroidTool" i can press button "ereaase IDB" but it dont erease it .. it just showing me "IDB ereased seccess".

 

only one time i had green colored connected device then i'm abled to erease idb and restore device but device had black screen and screen backlight was on.

 

what i'm trying to do is to just abel to press button "Upgrade" and it goes successfully without any errors.
