Linux Users, Coby 8042, Root, Recovery, Update, All Without Livesuite

[vampirefo.]

Thank you, may this work on an imac?, using the "terminal.app" that comes with it?

Yes as long as you have adb setup.

Is there a video to show you how to do the root? Sorry didn't have the chance to read the whole thread. Thanks for your root Vamp.

Im not sure if theres a clockwork recovery for your model. This one is for the 8042 and may not be comapable with yours. The instructions for root would be the same, tho. If you want a somewhat automated version, try this thread:

Development Index and Root Utility

Maybe you could do the video

tpaine I thought it worked for the 9042? Will this work on the 9042?

There is a ClockworkMod recovery for the 9042, linked in the Development Index and Root Utility. If you're running Windows, carefully following the directions in the thread should get you rooted with Google apps installed.

 

[afterlife2]

or this one?

 

[Traveller]

That root process will not work on any Generation 3 tablet.

Thank you Traveller1701! Which one should I use to root the 9042 and get marketplace and flash? I have windows 7.

 

[Traveller]

tpaine told you where to go.

I just got my 8042 today,all help here, so far is only for windows users, "LiveSuite", if you are happy with livesuite you may use it, however it has two major set backs, one it's only for windows users, second if your usb malfunctions you are out of luck.
I have read through most of the 8042 threads, and have taken from them what I needed, "temp root", from that we can do almost anything.

What I will be covering in this thread is how to root, install recovery, install a modified boot.img, install a custom rom. all without using "livesuite"

You should check your boot.img md5sum, if your boot.img md5sum doesn't match eda433b85d9729422a4be5889982d46d this update isn't for your tablet, you can still root and install recovery, but not update nor boot.img

you will need adb setup and working, I am a Linux user, don't want to use windows to modify my tablets.

Anyway lets begin.

download 8042_root_recovery.zip

8042_root_recovery.zip


extract to your desktop you should have a folder called data, and a text file root_recovery, it contains the following commands. type one command at a time allow each command to finish before typing next command.

The first command is simply coping the contents of the data folder to your tablet, the second command is asking for shell, third and fourth commands are setting permissions, fifth command is sending exploit, sixth command is asking for root permission, seventh command is installing recovery, eight command is booting into recovery.

open a terminal

adb push data /data/local/tmp/

adb shell

chmod 0777 /data/local/tmp/mempodroid

chmod 0777 /data/local/tmp/install-recovery.sh

/data/local/tmp/mempodroid 0xd7cc 0xad27 sh /data/local/tmp/root.sh

su "Note at this point you can backup your system, recovery and boot.img, you don't have to but you might want to, see note 1 below."

/data/local/tmp/install-recovery.sh

/system/bin/reboot-recovery

once in recovery

volume up and down to navigate power to execute. silver button is back.

at this time you should make a backup.

download 8042_boot.zip

8042_boot.zip


adb push 8042_boot.zip /sdcard

then use recovery to select install zip from sdcard and install it.

reboot

download 8042_update.zip

8042_update.zip

place on sdcard

adb shell reboot-recovery

select install zip from sdcard and install it.

If there is anyone that I left out of the credits, please let me know so I can give you credit for any work that I might have borrowed.


Note 1 if you want to backup your recovery, boot.img and system before making changes run commands below.
adb shell
su
mkdir /sdcard/dump
cat /dev/block/nandc > /sdcard/dump/boot.img
cat /dev/block/nandg > /sdcard/dump/recovery.img
busybox tar -cvf /sdcard/dump/8042_system.tar /system

then use either adb pull to put them on your pc, or mount the tablet with the pc.

after recovery is installed

to boot into recovery from shutdown

press an hold volume up + back press power release power at coby screen keep holding volume up + back until you see cwm screen.

to get into recovery from normal mode download terminal from market

su

reboot-recovery

or from adb shell

reboot-recovery.

Quick question how do you check if your boot.img md5sum matches? Expecting to get an Kyros 8042 for X-mas just doing so Homework before I get it.

Hey guys I ran into a little issue. The touchscreen doesnt work. I flashed the 8042_update.zip and I have an 8042, everything went smoothly and when the tab booted up I cant press ok. I rebooted into recovbery and reset factory and cache again and when it boots up I am stuck at lock screen. I was able to get into it by hooking up a mouse but I dont know what to do next. I made a backup and it is in my sdcard directory in a folder called dump in three files. What should i do? Restore? if so how? or start over from scratch and try again.

Flash your clockwork backup from cwm recovery. you will be just where you were before you applied the zip file.

You can check hte md5 sum from ex file explorer on the tablet. On your desktop you can download an md5 checker (md5checker works for me.).
