Ok I've got a generic tablet from Walmart, the DOPO MD-740. It's running ICS 4.0.3. I've been in contact with customer service about this thing, and while they're friendly and courteous, they really don't know anything about their product. According to their lead tech "there is no recovery or download mode".
Headache.
Well fooling around with this device, I've found.... SOMETHING....
While holding the volume up button at the same time as the power button, it boots straight to one single image, shown below. I have a feeling it's the download mode. Whatever it is, it's progress. Can anyone recognize what I got into? It's not a fatal error-- when I hit the reset button and reboot the tablet normally, all is fine.
I've tried to reboot into recovery via adb but I get the message that the command is not allowed. And of course, su is not allowed either.
Anyone have any suggestions on running adb on my computer... what process I would need to follow to manually root an ICS tablet? Would I just follow the same steps as I would in manually rooting a gingerbread device, or is there different lines of code I would need to use for ICS?
As for what device the kernel for THIS device has been ported from (it's obviously emulating something that has a magnometer which this unit doesn't have, etc...)... tech support doesn't know that either. The only clue I have that MIGHT help (other than the kernel version, build number, etc... all this is documented in another post, if anyone cares to take a look) is the FIRST boot image is of the penguin.
I would appreciate ANY feedback/information/advice anyone could offer in progressing with this "adventure"!
Thanks
Well with another twenty minutes of blindly pressing buttons I've found the recovery mode. From the screen displaying the android with the open panel (which I have concluded is NOT the download mode), pressing volume up, back, and power at the same time opens the recovery mode. The recovery is:
Android system recovery <3e>
Recovery system v4.00
No option to apply zip from sd, I guess this is to be expected on a stock device.
hi
in application select usb debug mode
install from unknown sources
connect to pc and run DooMLoRD_v4_ROOT
should work
regards
fred
didn't work.
After adb started successfully, sat for two hours and did nothing.
hi
are you using windows ?
is it reconized by windows ? do you have the drivers installed ?
ich processor use that tablet ?
Yeah I'm running Windows Vista, and my PC does recognize the device when it's connected (says drivers have been installed properly when connected under USB debugging mode, no problem transferring files in USB mode)
It's the ARMv7 processor
The device is recognized as Full ASOP on Rk29sdk
I've run across a new problem, which might actually be the main issue of the WHOLE problem. I was trying to push some files with adb from my laptop and it came to my attention that the driver for my device only acknowledges it as a mass storage device, even when the tablet is NOT mounted for mass storage. SOOOO... I guess I need a driver that will allow me to use adb. Any suggestions?
did you try with the drivers package from sdk ?
yup. Even gone as far as uninstalling the adb and sdk programs I had on my pc, downloading the newest versions and reinstalling. My computer "recognizes" the divice, but only as folders. Even when it's not mounted as mass storage.
STILL having te driver issue. Anyone have any suggestions on how to fnd a driver that will work with adb?

How did I root my “Full AOSP Rk29sdk”-MID 7-inch tablet (Android 4.0.3)
Hi Wingnut79 and others,
I have an Android 4.0.3 Tablet 7 inch, named "Full AOSP Rk29sdk" - and was also eager to root it....
After hours of search, trial and error, I succeeded.
My tablet is now fully rooted, and I can use ROM manager and all the aps for rooted android-devices....
How did I do that ?
I explain it here, in the attachment...
As you can see, my Windows is in the Dutch language, so I nevertheless hope everyone can understand what to do where...
I hope this can help...
Make sure it's not a Chinese Apad!
Make sure it's not a Chinese Apad! If u go on ebay u will see tons of tablets with ics 4.0.3. but the android on it it's a modified and weird version. I doublt it even is ics. One of my friends have it, and he cannot use the App Market, bcuz it said "Device not compatible with Market". Did u successfully downloaded stuff form the Market? If not, that maybe it's a piece of Chinese crap and u should call walmart for a refund.
It downloads apps from Android Market, Getjar, Amazon etc... just fine.
BAUDI--
I will try this later this afternoon, is it going to be an issue that my laptop OS is windows vista?
Mine tablet is a chinese tablet - but it's clearly really Android 4.0.3.
So, I also download and install applications from Playstore /Android Market/ etc.
It has Wifi, Bluetooth, 3G, GPS-AGPS, FM-radio,.... and evrything works really fine.
My sole problem was: no rootaccess (what I didn't understand, because it's "Android Open Source Project"...?)
Wingnut79,
as far as described in the guide I refer to, it works equally well on Vista. Just sometimes a little bit other name or place to find the properties or so - but should not be a problem at all.
I forgot to insist on the need to kill and restart adb after each change. I am not sure its really necessary each time, but I experencied that when I first thought "again nothing", it seemed well to work after "adb kill-server" and then "adb start-server"....
At some steps (I can't remember wich) I even rebooted my PC....
Now, everything works immediately...
So ROM Manager etc. works well, I have SuperUser... etc .
Good luck!

Just because it says it is 4.0.3 doesn't mean its pure AOSP. Remember that the China gov has its hands into a lot and there are things that they like to install on their devices to monitor the users and then close it up so it can't be changed.

Hello,
So SuperOneClick did work for you?
What kind of tablet do you have?

I tried this and it worked. I got root on my device thanks alot for the guide.
Now to the real problem. I have two identical devices (rk29sdk). One is not booting and I can't manage to reset it.
My idea is make a full backup of the working device and somehow install it on the other one (the broken).
How can I do that - when I try to connect with adb it says:
Code:
C:\Windows\system32>adb devices
List of devices attached
0123456789ABCDEF device
Then this
Code:
C:\Windows\system32>
C:\Windows\system32>adb backup -apk -shared -all -f /backup/mybackup.ab
adb: unable to connect for backup
So it sees the device but I can't backup?
[edit]Now I connect to the device, the 'adb reboot' command works and the device responds. it's just the backup command that is not working.
Please help

The thing is I don't have access on my tablet. It won't boot.
So I can't start an app from the tablet, or maybe I can?
Hi to all here. i just want to ask anyone what to do with my phone. well first of all, my phone is a sky pantech vega racer im-a760s, not really a match for samsungs popularity but budget wise this is the model for me. it has a dual core. now my problem starts when i started editing the build.prop in its system (tweaked for some texting problem of limited character sending). of course i know what im doing on that part, but the only thing i didn't think that would happen was, i copied it in my computer, i edited it there, then i saved it as "all" in file type so it wont become a ".txt" format. but when i placed it in my phone. the file instantly disappeared, i think it was only hidden and the phone just cant identify it nor read it like something. now i restarted the phone, it booted up to its logo then it just went blank and it just stops there. i tried pushing recovery with adb in my pc cmd. but it cannot detect my device(no problem with my adb installation to eliminate this from the question), i also tried putting an sd card with a recovery file but there was no option for sd card path. but the phone can still function well, i know because it can still be loaded under flashboot, download screen and S / W upgrade menu and it can still perform wipes for all partition and caches and can reset for factory settings etc. but whenever i will reboot, its not going to complete. anyone please help me how to make my phone be detected by my pc. The usb drivers are just fine, updated it many times, read all procedure for making the driver connect perfectly. i reformatted the sd so it wont be a problem when i put it in. but in the recovery menu i just cant see my sd card, theres just the option for "update from external storage" but it doesn't have anything inside. what a mess. i cant make my phone reflashed cause its not responding with the connection with my pc. but when i am opening an odin (just used for connection monitoring) there are two yellow boxes with com port like these: 0:[com7] and 0:[com9], so i know it is still somehow communicating with my pc. please help any advice, i dont want to resort to jtag for im not sure if it will support my phone and it's already avialable for the model but definitely not going to send my phone for repair cause it will be costly. thanks to all who will respond. Please help thank you. additionally: OS was ics version 4.0.4 and rooted. already gone through rooting several times with no problem. just the editing part.
to edit Android files on Windows use only Notepad++ anyway do not use Windows notepad this is for Windows files formatting only
well, you have to get build.prop from your phone edit on PC then copy back
so enter recovery connect phone to PC create a folder say C:\tmp
to get build.prop from phone
Code:
adb devices
adb shell
mount system
exit
that's to mount system partition then
Code:
adb pull /system/build.prop C:\tmp\build.prop
edit it and copy back to phone
Code:
adb push C:\tmp\build.prop /system/build.prop
maybe is not your case ? but I wanted to give you an idea
@ruscan.calin
Thanks, great. i will try this one once i get my phone recognized by my pc, adb seems not able to find my devcie have this message like this one:
"
c:\>adb devices
adb server is out of date. killing...
*daemon started successfully *
list of devices attached "
and that's it nothing happens.
thanks for the advice i will definitely use this once i get my phone connected with my system. thanks a lot

start phone in recovery mode do not connect to PC at this time
open Device Manager now connect phone to PC
if you see ADB Interface connecting in Dev Manager it's ok if not you have a problem with phone drivers so install it again

Hi, cant still afford to make the adb component in my device manager to appear, but it's good to inform you that it helped me a bit because i was able to see the storage of my phone and i was also able to put some files in there without any hassle that alone was satisfying me that my phone is not really dead. sad to say i did everything i could to have my pc detect my phone via recovery menu, but still no devices found. it's really weird that some links are saying that i should make my phone's "usb debugging" enabled, wherein fact i cant even go beyond my original problem(bricked phone), i can't even see the inside of my phones directory, only the storage one that was activated just recently. i even did a reinstallation of my usb, uninstalled every other phone related usb installation to avoid conflicts reinstalled my phones proper usb installer then restart. no progress still to be called. it makes me feel that the phone was just trap in the state of booting and not knowing what to do because it cant see any command inside its system. i cant go into the systems directory as well. and that's the only way i think i could revive my phone in replacing a new build.prop, as you advised to be edited in a notepad++ which i recently acquired and installed. by the way how do i save the build.prop to its original file format, and what is the extension. thanks alot for helping out. im getting a little brighter each step of the way, im not loosing it to come to smashing my phone to pieces instead of keeping a very expensive paper weight.
usb debugging enabled is not useful in this case (you can't set it )
build.prop is a file with .prop extension save file with notepad++ name it build.prop then check location of file it should be build.prop notepad from Windows saves it as build.prop.txt that's not good also notepad adds some formatting characters inside file that's wrong so use only Notepad++ when working on Android files (or VIM for Windows editor etc anyway do not use Windows editors they are good for Windows files only)
-try these things on another computer (to install drivers etc)
-I advised somebody to send a mail to manufacturer and he got a reply with a link to stock rom... that's great !
-if you link me your build.prop file I can tell you if it's ok
-pc link - that's to be solved firstly check manufacturer site for sync software/ drivers even send mail

that's great news, you actually come to emailing the phones manufacturer? wow, im flattered. well you're a very nice guy to help me out on this. and i have good news too. i found out that i have a little conflicting usb drivers, as i have installed samsung for my previous phone(samsung galaxy 1) i had it liquidated for this new one. but a little hard on the support. you gave me a new idea about the usb. so i uninstalled all the related usb drivers and have it reinstalled. now i am able to communicate with OTA firmware server, and i got a reading that was not happening before(stucked in just detecting the phone) now i have a percentage reading of downloading or so. but i still have to wait if it will complete and have it repaired. so by now you can give me a little more help cause im still not at it in pushing through the use of adb programming. and the link you mentioned, i'll wait for the progress about it and see what really was it. and thanks a lot. really appreciate it.
fixed bricked phone via OTA by fixing link to pc.
Hi, i thank you for your help. i managed to fix the phone myself. i just missed the simple step that you advised me. fix the link first to pc. i have installed another model of the phone for the same manufacturer with different type so that was causing the mixed up for updating and recovering via the OTA site of the phone. so yey. you helped a lot. i thank you. i am now running at ics version 4.0.4 and now rooted. i will not commit the same mistake of saving the build.prop with another format. that was bad. so then i'll be very careful in editing the build.prop and first of all, i will keep a backup inside where i can access it even if it will be hard bricked. never forget that one from now on. so this is it. i thank you. of all the place ive been circling around for answer. here is where i found it. and just one person. hooray. thank you very much.

feedback is an invaluable resource ! (some just forget about that from my experience :laugh: NOT your case ! )
Hello everyone,
A device of mine fell into the hands of someone whom I'd rather it didn't. This person is computer literate enough to try something. I have encrypted my phone, which is running CM10.1 (an android 4.2.1 variant), and have employed a password (not a pin code).
I wonder how secure the encryption function is. From poking around the net, I've learned that if one can obtain access to the phone's system partition, one can grab the password database/hash, desalt it, and run a brute force on it. This is assuming that one can get into the phone and grab that file, which is not possible from recovery at least (mount operations are apparently protected by encryption). My bootloader is unlocked. I wonder how worried I need to be.
Note that I'm not asking for instructions on how to crack through a phone's password screen; I'm merely asking if it would be possible so that I can know how secure my data is. What do you guys think?
Cheers
If you had Enabled USB Debugging then he can easily get access to your Files.He Just needs to pull them on his computer which is very much possible.Or if you had a custom recovery he can create a Nandroid and then get access.But if you dont have a Custom recovery or USB Debugging enabled then it should be hard but not impossible.

Hi, thanks for that.
I flashed ClockWorkMod recovery so that I could flash ROMs to the phone. It's possible to reboot into the recovery menu, but because it's encrypted, there's no way to mount the USB storage and push files to the phone. If USB debugging is disabled, would it suffice to keep CWM on the phone?
