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..

Hello,
I'm new to tablets and their operating systems. I was wondering if anyone knew how to root the dopo D7020 tablet. It was gift for my children and I would like speed it up so my kids don't come up to me 5 minutes telling me that it's froze.
Thanks and any help is appreciated,
Jon
Rooting won't fix your problem. A custom rom is needed and it's hard to find these for such tablets.
I'd recommend using a lightweight launcher so you have more free RAM.
Stuck in CWM 5.5.0.4 No ADB DOPO D7020
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.

How did you go about rooting?
No expert but I can suggest ADB...

Using windows or linux, please try to boot into CWM (since it only does that I'm sure that's automatically) and then use ADB to push, pull or even restart in bootloader or recover mode if I"m not mistaken. The commands are "adb reboot-bootloader" and "adb reboot recovery" without quotes. This should allow you to work with your phone. Use ADB to reboot into the bootloader (fastboot mode) and then use fastboot to flash whatever you may need. Hope this helps. I spent a lot of time working on my kids Tablet too and ended up in a similiar situation.
-Q
Cheers! Good luck.
I have a Galaxy Tab 2 7'' Wifi (P3110) with CM 10.1.3.
Thing is, I wanted to install the latest nightly, so I booted in Recovery mode, tried to install the zip file and I had a Status 7 error. So after that I decided to stay with my CM version, but when I try to boot the tablet it goes to recovery mode and doesn't boot! I tried to wipe everything and still. I can't flash anything else (not even the CM version I already have) because I keep getting the Status 7 error.
I am desperate, I don't know what to do!
Well, you attempted to flash CM11/Omni with the wrong recovery, that's why you got the "Error 7"
Anyway, the problem should be easy to rectify.
1. Install ODIN3 on your computer (don't forget to also install the Samsung USB drivers as well).
EDIT In case you are about to install the drivers by installing "Kies" ... make SURE that NONE of the Kies components are running in the background (on Windows) once you try to flash with ODIN3 - or it won't work. If you Google around for a bit, there are several Downloads for JUST the USB drivers - I can upload you the USB drivers installer I used for my P3110 (flashed back to Stock to sell it off)) /EDIT
2. Download the correct .tar.md5 recovery file for the ROM you're going to use from Android Andi's file repository.
For CyanogenMod 11 you want to grab either PhilZ Touch or CWM Swipe Edition, for OMNI you want to grab TWRP.
3. Start ODIN3 and select the <recovery>.tar.md5 as a PDA file (make sure that nasty checkmark at "Repartition" is NOT checked"!)
4. Power on the tablet and make sure you get it into Download Mode
If it boots into Download Mode itself, that fine. If not just press... was it Power + VOL Down?... until you see the screen telling you to pres VOL up to proceed into Download Mode.
5. Connect the tablet to the computer (wait a second in case Windows decides to install the driver)
6. Flash the recovery
7. Disconnect after flash, jump into the recovery, flash CM11 or OMNI
Of course you can also flash back to Stock ROM (given you have the ODIN flashable tar.md5 at hand), verify that it boots after flashing, get into download mode, flash the custom recovery, flash the custom ROM.

Thanks! I didn't know that was a recovery problem!
Somehow I couldn't reboot into Download mode with the key combo so I used ADB for that, and flashed the new recovery with Heimdall (in the CMW official website the versions are old, maybe that was the problem...).
Then I installed CM.
Thanks again!

I am aware you managed to flash the ROM, but just as a hint about "this is a trap for young players":
IF your tablet is connected to the wall wart (power supply) or to the USB port of computer while trying to trigger the key-combo to hop into download mode or recovery it won't work! Your tablet needs to be _disconnected_!
Update Recovery!
hey you can try update your custom recovery to latest version by downlading the zip file here http://forum.xda-developers.com/showthread.php?t=2548257
and than try re-flash your current rom or any kitkat room for your device
I have a nexus 5 16 GB and i downloaded the recent software update android 6.0.1 and then I decided to root and I used 'Nexus root toolkit v2.06' and first unlocked the bootloader and then rooted. Everything worked fine but after the process was complete it was rebooting and the booting animation went on and on for many hours and the device did not root. I really don't know what's going on. My purpose is to install a custom rom: cyanogenmod 12. Now what should I do ???? PLEASE HELP. When i try to enter recovery mode it shows a picture of the android mascot with opened back and exclamation and cannot enter command as well. and after some time the booting animation begins and goes on and on...
please help...

Unless something has changed, version 6. requires that you flash a special kernel before you can root your phone otherwise you are as you are now, stuck in a boot loop. You should probably download the factory image from Google, and then flash the system image to get rid of what you have done.. Perhaps then your phone will start normally

Thank you very much for the reply, I really do have no idea as to how to flash the factory image because i am very new in this area. Could you please recommend software and which factory image i should download, please ?? thanks very much.
:good:

Also, you mentioned a 'special kernel' what does that mean. All i want to do to my device is install cyanogenmod 12 and for that i believe it needs to be rooted, so i am really confused. What should I do know
I'm having this same problem, and unfortunately, when I start the phone on fastboot, I can not access the recovery mode in order to upload a factory image of nexus 5.
I used the new tool available her for quick flash, and now, I don't have a phone.
First, don't panic. Your phone is still very easy to recover. Unfortunately I can't get you a complete walkthrough here (for now at least), so I'll give you the main idea and you'll have to do your homework (as maybe you should have done before).
1. You need to get fastboot working on your computer. It's included in the Android sdk package, but there might be some easier way to get it. Google it. You might need drivers for your pc too. Google it as well.
2. Then you need to get into fastboot mode on your phone. To do it, hold down power button AND volume down button until it gets into fastboot mode. You will see an android on his back with the cover open. At this point, connect your phone to your pc, open a terminal on your pc and type "fastboot devices" without the quotes "". It should find your phone if fastboot is working. If it doesn't work go back to step 1.
3. Download TWRP recovery on your pc and place the img file in the same folder as your fastboot executable (not mandatory but easier). It can be found here https://dl.twrp.me/hammerhead/
4. Always in fastboot mode, type "fastboot flash recovery twrp-2.8.7.1-hammerhead.img" assuming you downloaded that file, which you should have by the way. It should install fine. If you haven't placed the file in the same directory as your fastboot executable, you will need to provide the path to your img file as well.
5. Then use the volume rocker to switch between modes and choose reboot recovery.
6. You should now be in TWRP recovery. At this point, download a custom kernel (anyone found on xda for hammerhead should do) and push it to your phone. It should be fairly simple with TWRP. Then flash your new kernel using install. It should help you get your phone booting normally. Alternatively, you can download a custom ROM like cm12.1 and flash it altogether. It will install everything needed for your phone to boot up too. Beware if flashing a ROM though, I strongly advice you to do a factory reset before flashing it. You will find that option in the wipe menu.
Hope it helps, let me know if you need further assistance.
Yesterday, I have tried everything to have my computer to recognize the "fastboot" command, and I installed like 2 or 3 different programs for that. With my old Windows 7, I have been able to push a flashed image to fix this issue, using the fastboot command, but with Windows 10, it's always telling me it's not a valid command. I'll keep trying it, otherwise, i'll have to "resurrect" my old Windows XP computer.
Also, I noticed now that, while trying to install the fastboot, as per some files that I could download, but no file has been copied into my computer, not even if I run it as admin.
fixed. but no RECOVERY mode options....
Hi Guys,
Thank you very much for the help, I have finally recovered the phone and running android 6.0 MRA58N but it is not rooted. Now if you don't mind could you teach me how to root because i have checked lots of videos and tuts but none worked for me...
IMPORTANT:
when i am in recovery mode why cannot I access options even when i press volume up + power button and release them at the same time...????
Thanks in advance.
Just flash a custom recovery via fastboot. Just make sure your bootloader is unlocked. Can't link though.
hi guys i have used nexus 5 mobile with cyanogenmod 14.1 .It worked properly in 1 year. after that suddenly switched off and it not properly boot up .i try to switch on my mobile , first it show google with unlock logo properly and when it show cyanogenmod logo it stuck and again show google with unlock logo....i try recovery mode to wipe and flash the same rom ....the process is interrupt at middle stage and again show the google..i try lots of time . after few try that process finished completely without interrupt. then use my mobile 1 day same as i used first time root. after that same problem occur on my mobile ..so help me guys
@[email protected], possible power button problem?
Hello, first post on XDA forums.
In one sentence, my goal is to back up data from a tablet that doesn't boot beyond the Samsung logo.
Details:
- tablet: Samsung Galaxy Tab 2 7.0", model GT-P3113
- problem: when you turn it on, it boots to the point of showing the Samsung logo and is stuck on it
For the past 2 days now, I've been trying to figure out how to back up data from this tablet so that it can be put on a new tablet.
During these 2 days, I educated myself on Android and especially how to use Odin to install new firmware and I've been reading about TWRP. I learned about recovery mode and download mode.
I was able to use Odin to load a ROM image for version 4.2.2 and according to Odin the process went through without issues. However, that didn't fix the boot problem, it's still the same.
I even wiped the cache partition in recovery mode but still the same problem.
I was very hopeful today that I would be able to use ADB with the "pull" command to save the data to a computer. Unfortunately, after installing ADB on my laptop running Ubuntu, it doesn't see any devices connected. My understanding is that with Linux there is no need to install a driver unlike on a Windows PC.
Current situation as I type this message:
- stock tablet, not rooted, default recovery system on it (Android system recovery <3e>)
- tablet in recovery mode
- tablet connected to computer via USB cable
- ADB installed on Linux computer
- the command "adb devices" returns no devices found
Question to you guys: if the tablet is in recovery mode, shouldn't ADB see it on the Linux-based computer?
Please advise.
Thank you in advance for your help. :fingers-crossed:

It seems u got stuck in the bootloop, try to wipe data/cache/dalvik ur device and I think it would solve ur problem
root the tab, install custom recovery twrp and a nice marshmallow custom rom. then you have a new device.
why backup data from a non booting system?? for me it makes no sense.

considering you never rooted,
and you were on stock 4.0.4 or 4.2.2?
whichever version you were on, you're supposed to use the same firmware build which you were using before.
different firmware flashed on another Build's data results in bootloops as well.
solution: you should flash a custom recovery first instead of a firmware. that will not erase the data.
then you switch to recovery, make a backup of the data partition.
save it on your ext card.
wipe your system,data, factory reset.
flash the official firmware you were using before.
let it boot.
flash custom recovery again.
restore data and check.
if it still goes into a bootloop,
try entering safe mode.
you can get an app that can restore selective data from nandroid backup. (forgot the name but it was on play store) or you can extract from the backup the data you need.
there is a detailed guide link just below here in my signature. you can give it a read, when you feel like stuck somewhere.
