hello everyone. i just want to ask if there is someone can help me about my Coby Kyros 9740. it was stuck on CWM and i don't know what im going to do now. please help me, thanks in advance.

I am impressed, I had talked to Coby sometime ago they told me they would be taken actions eg modifying their tablets to prevent the use of the livesuite and to protect from a certain dev. So this is it, I have looked at your dump and see what they have done, I wont post how to defeat this security.

I will warn you not to try any roms or any livesuite images, you will regret it.

your rom is the newest that I have seen

ro.build.date=Wed Feb 20 18:51:54 CST 2013

Ok download and flash below recovery, it will allow you to do what you want, again do not install any roms or livesuite images period.

9740_secure_recovery_signed.zip

After you flash new recovery, power off tablet wait 1 minute then restart tablet this will reset one lock on your device, and it will be able to work correctly.

By the way, your rom is 4.0.4 while other roms are 4.0.3 so I may try and install your rom on my tablet to see if there are any improvements beside the added security.

hello sir, thanks for your reply. here's what i did. i've downloaded 9740_secure_recovery_signed.zip then i "install zip from sdcard" then i select the file that you gave to me. then after i install, i turn off my device in 1 minute then i turn it on after i minute but i still back on cwm. did i do it right sir? sorry for bad english.

ah sir, is there any software like livesuit that can flash my device even in cwm mode so i can use the file that you gave to me?

 

[vampirefo.]

in cwm select wipe cache partition

after wipe cache is done

mount and storage

mount /cache

then reboot system now

 

[xanvier]

after i
mount /cache

it say
Error mounting /cache!

 

[vampirefo.]

are you sure you flash new recovery?

do you have adb setup?

 

[xanvier]

sorry my being noob sir. i only use cwm to flash the file that you gave. i don't get what you by to flash to new recovery and about adb setup. can you guide me sir on how to do it. your the only hope i have to fix my mid9740.

can i flash the file by using adb shell? if can, what command should i use?

 

[vampirefo.]

Ok download 9740_update_signed.zip place on your sdcard

install 9740_update_signed.zip

in cwm select wipe cache partition

after wipe cache is done

mount and storage

mount /cache

now install 9740_secure_recovery_signed.zip

then reboot system now

 

[xanvier]

i made video on how i use the file that you gave to me sir but im still no luck. please watch the video sir and see if im doing it right.

 

[vampirefo.]

You are doing it correct, just your cache isn't mounting so it's blocking the install.

Ok you have adb working so lets go that route.

download nand.ko

place nand.ko on sdcard

then mount sdcard in cwm

note using adb type one line at a time press enter after each line, so the command is give to the tablet.

open terminal

adb shell

busybox cp /sdcard/nand.ko /tmp/nand.ko

chmod 644 /tmp/nand.ko

insmod /tmp/nand.ko

lsmod

mount -t ext4 /dev/block/nandh /cache

rm -r /cache/*

now install 9740_secure_recovery_signed.zip

Below is what the commands look like in terminal.

root@Vamp:/home/vampirefo/Desktop# adb shell
~ # busybox cp /sdcard/nand.ko /tmp/nand.ko
~ # chmod 644 /tmp/nand.ko
~ # insmod /tmp/nand.ko
~ # lsmod
~ # mount -t ext4 /dev/block/nandh /cache
~ # rm -r /cache/*
~ #

 

[xanvier]

~ # busybox cp /sdcard/nand.ko /tmp/nand.ko
busybox cp /sdcard/nand.ko /tmp/nand.ko

~ # rm -r /cache/*
rm -r /cache/*

2nd try

~ # busybox cp /sdcard/nand.ko /tmp/nand.ko
busybox cp /sdcard/nand.ko /tmp/nand.ko

chmod 644 /tmp/nand.ko

~ # busybox cp /sdcard/nand.ko /tmp/nand.ko
busybox cp /sdcard/nand.ko /tmp/nand.ko
~ # chmod 644 /tmp/nand.ko

look at above commands again

insmod /tmp/nand.ko you are missing insmod from the command.

try the commands again.
