[Q] [HELP] How to back up stock rom (& upgrade) for UNKNOWN brand tablet

Hi guys.
I've recently bought a android tablet,
the brand was MBI and the model was i7
(which is a not known brand ... can't find much info about it).
In my quest of rooting it, I've lost the bundled disc (with Win32 driver). after reading up tons of articles. I've decided to download google's USB driver and edit the .inf, the the tablet's VID & PID info. Somehow I managed to get adb working.
And for rooting, I've tried .apk and none of them work, then I proceed to SuperOneClick and it hung. Lastly I've tried the Easy Rooting Kit by ZoomLord and ta-da, my device is rooted!
Then I attempt to back up the stock rom in case of anything. But Rom Manager kept restarting the device whenever I run 'Back up current ROM'. And when I try to flash the ClockWork Recovery Rom .. the only option was 'Nook Color' & version 3.2.0.1, even Rom Manager reported recovery rom flash successfully, but whenever I try to boot to recovery mode, CWR is not running... and default recovery image doesn't allow me to back up my rom either.
So, in short, I hopes any of you could help me out on following:
1) How do I backup stock rom? or get any recovery rom working?
2) After that, can I just flash to any custom rom? e.g., CM7 Gingerbread ROM? although my device isn't in their supported list?
any help will be appreciated, thanks.

Now I'm trying this fastboot,
somehow when I entered fastboot mode (hold Vol+ & power the device on).
"FastBoot" was showed on center of the screen,
but whenever I issue # fastboot devices
the device will reboot itself ....
any idea? I was trying to flash recovery image via fastboot here

hello
did you manage to root your phone as I too got this tablets thanks

I have a same problem too.. can't use cwm after rooting. Now my mbi i7 tablet can't be used anymore. It just show blank screen after boot up. I can't revert it back to factory setting because the rom is corrupted & the update.zip file is missing. Can anybody upload the update.zip for mbi i7 tablet please.. - sorry 4 my bad english..

[Q] DOPO D7020 Stuck in CWM no ADB

So I rooted the device no problems , and I used a generic CWM recovery for RK2918 devices, since I thought thats what it's running
Livesuit Shows no Rockchip device , it is now detecting a A10 device and I cannot load a Rockchip driver for the life of me , in the CWM recovery mode.
1. Is this device rockchip or not?
2. I have no control with volume controls can only press power which reboots right back to CWM
3. Is there a proven recovery technique for this issue?
4. Does anyone have a backup <--- I was installing CWM to do this I belive I may have put the wrong on or
5. The factory firmware image <----- Double powertech site does not even list this tablet.
6. Is there a way to get the device out of CWM recovry mode? Yes I have done a hard reset via the reset button still CWM recovery.
Device is a DOPO 7020 it detect under windows as a D7016 though
Im not sure how to get out of this if I could even gain control of the menu up down to apply an update from zip this would be fine. I can work in WIN. MAC, Linux dont matter just need to get it working agin for my kid. Any help wold be appreciated.

RK3066 Boot loop in recover mode

hi i purchase China brand rk3066 label as UG007 II
here the story
i wanted to flash finless rom on the stick but i want to backup my stock rom thru CWM
firstly i tried to root, using petrus. install it. run the reboot apk. when i choose reboot to recovery, my tv reboot and after awhile it goes back to home with ALL my apk missing. it seems that chat comand has factory reset my tv stick.
secondly i tried this method from Geekbuying website
install moroboro, and tpsarky successfully and my stick now rooted. moroboro successfully detect the rk3066 chip.
thirdly i want to install cwm as i want to do nandroid backup from here and choose genericrk3066 as i am not sure whether i should use imito or ug007 as this china brand tv stick
so.. following the method rename the cwm to update.zip and placed in external usd lashand reboot.
upon reboot, it goes stright to recovery menu ( it takes quite sometime to reboot probably few minutes). but unfortunately i cant move my mouse up/down. the cursur stuck at reboot system. when click the mouse, the stick reboot.
no matter what i do the cursur wont move and i cant highlite the install from sd to flash rom.
so no i am stuck at recovery mode.
worse part is the reset hole/button seems doesnt do anything. presing it while in recovery mode does not do anything.
if i press the reset button and connect microOTG to notebook usb (tried many method combination microOTG/power/reset), my notbook cant find the driver. if i able to do it, i able to flash new rom. but unfortunately. but Moroboro still can detect the stick when i install it.
anyhelp can extend to me please. i have open up the stick at techbliss website says you can short two point to go into mask recovery mode but the circuit is different:crying:

I able to flash new rom now. there's program to install rk driver. forgot to backup the rom before I flash new rom, now my wifi won't work anymore

boot problem

When i boot or reboot my rooted my Samsung galaxy grand prime g530h it directly enters in recovery mode , WHY ?
Due to this problem my mobile does not show battery percentage while charging switched off mobile.
Even when i have not installed any rom , why does this problem occur ?
The only thing i did was just rooted my mobile using odin .
But , I do have custom recovery CWN
Why does it boot or reboot in recovery mode ?
What should i do to solve it ?
Need an quick answer .

Depends on the situation on why it boots to recovery. Probably would need more information. Do you have a custom recovery and if so what one? What were you doing before this behavior came into play. Please give as much detail as possible and I might be able to help you. Or someone else can.

Wow. Sounds to me in my opinion that u soft bricked your device. But have no fear. Samsung devices are virtually impossible to perm brick as long as you operate Odin correctly. First thing your going to have to do is find an custom recovery to put on the device. In my opinion as soon you rooted you should of done it because people do make mistakes.
I do not own a Samsung device personaly my wife does but she won't let me touch it LMAO. Try searching on Xda for Samsung galaxy grand prime g530h softbrick

Universal unbrick guide:
Terminology - types of bricks:
Soft brick - often occurs in the shape of a bootloop or any other problems with booting such as always getting to recovery or not getting past the carrier logo. This type of a brick, which shows some signs of life, can in most cases be fixed.
Hard brick - As the name implies, your phone can essentially used as a brick and it shows no signs of life. This kind of a brick is rare and in theory should be unfixable. However there are advanced methods of fixing your phones such as JTAG, but they require extra tools and accessories.
The decision:
Is my phone soft or hard bricked?
If you answer yes to all of the questions below you probably have a hard birck:
Test as said in order!
Nothing happenes when you hold or press the power button
You cannot get the screen to even turn on by pressing or holding any combination of buttons on your phone
Nothing happenes if you do the same as about but with your phone plugged into a charger
Nothing happenes when you plug your phone into a computer
When you plug in your phone into a computer it does not recognize it as a phone, storage or any other media device
Nothing happenes when you try all of the above again, but with removing the battery in between steps for 10 seconds and putting it back in again
Nothing happenes when you try all of the above again, but after leaving the phone plugged into a charger for 2 hours
If all of the questions are a "yes", then you either have a broken charging port and and a discharged battery or you have a hard brick.
The unbricking:
There are many methods of unbricking and they are all different to each phone. Here I will list the most common methods that often succeed.
Samsung users skip to 4. method.
1. If you have access to a stock recovery:
Method 1:
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Choose “Wipe Cache Partition”.
5. Choose “Wipe Data / Factory Reset” to delete all your settings and apps, using the correct ROM.
6. Reboot your device.
Method 2:
Download the stock rom for your phone. It should be in ".zip" format. Make sure it's the official version
(Find it by Googling something like "[your phone model] stock rom")
Put the file on your phone's external SD card.
Make sure that the rom is for your exact phone model.
1. Shut down / turn off your phone.
2. Boot into Recovery mode – hold down the volume down button and then hold the power button (the button combination is different for every phone. Look yours up on Google)
3. Use volume keys to navigate the menus, and power button to select the menu items (Again, might be different for every phone)
4. Select "apply update from external storage"
5. Navigate to the zip file you copied to your phone
6. Install it.
If you get Status Error 7 that means you didn't download an official stock rom.
2. If you have access to a custom recovery:
Method 1:
Try stock recovery method 1
Method 2:
1. Find a stable custom rom for your phone or if you want to download the stock rom
Make sure that the rom is for your exact phone model.
2.. Copy the zip file to the phone's external SD.
3. Install the zip
(If you have a custom recovery you probably know the drill)
3. If you have access to fastboot mode:
First install ADB and fastboot drivers (if you haven't already):
To install it on windows there is a handy tool called the 15 Second ADB installer which will install pretty much everything you need.
On Ubuntu install with:
Code:
sudo apt-get install android-tools-adb android-tools-fastboot
On Fedora:
Code:
sudo dnf install android-tools
On OS X using Homebrew:
Code:
brew install android-platform-tools
Once you have the drivers installed you have to find a recovery image for your phone to install a custom recovery.
You can try one of the popular recoveries such as CWM or TWRP.
You need to get the recoveryNameHere.img file for your phone.
Find it by Googling:
"[your phone model] TWRP recovery"
or
"[your phone model] CWM recovery"
Make sure that the recovery is for your exact phone model.
Now on your phone enter fastboot mode:
Turn your phone off.
You can try different button combinations. For my phone it's holding power and volume down buttons.
Once you're in fastboot mode plug your phone into a computer and open your terminal/cmd.
Type in:
Code:
fastboot devices
You should see a list of devices. There should be only one device ID number.
If you see the ID it's working. If you don't you didn't install the Google USB driver properly (on Windows) and if it says "'fastboot' is not a recognized command" or "No command 'fastboot' found" then you didn't even install your drivers.
If you have problems with installing Google "how to install adb and fastboot drivers"
Now that you know fastboot is working type in:
Code:
fastboot flash recovery C:\Path\To\Recovery.img
Replace "C:\Path\To\Recovery.img" with an actuall path of the recovery file you downloaded.
It should say success.
If it doesn't try to execute:
Code:
fastboot oem unlock
This will delete all data you had on your phone (games, game progress, apps...).
Now try
Code:
fastboot flash recovery C:\Path\To\Recovery.img
again.
Once you're done type in:
Code:
fastboot reboot
And your phone should still not work. Now what you have to do it try the custom recovery method above (number 2.)
4. If you have a Samsung device:

No you didnt do anything wrong. Some h/phone models do not respond to Vol+/- + Power. Out of the 11 device I owned my latest MTK powered phone do not respond to the hardware button.
But you did not describe your phone completely.
What SoC? Kirin, Exynos or MTK? (I assume it is MTK)
Are you rooted?
Do you want to access customs recovery or stock recovery?
If you are not rooted and on stock recovery, you can only access (for these problematic models) via "fastboot recovery"
command. It is not hard install adb driver on your PC, and your device driver. search for "fastboot adb" installer from the web. It is less than 1 Mb size and your USB cable from PC to device. End users cant do much when facing this problem.
If you are rooted and on customs recovery all you need to do is to install "Rebooter" from Playstore and click the rebooter from Android homescreen to get into TWRP recovery. (this doesnt work if you dont have root and on stock recovery).
I rooted , install customs recovery, by using fastboot and my device ROM flasher everything works well for me. And I enter TWRP via "Rebooter" and clear my dalvik and cache. Try it.
