[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] No OTA for me and some noob questions

Hello,
I need some help to get the new ICS update. I have a TF101 (no G), serial B80, with firmware HTK75.WW_epad-8.6.6.23.
Previously I was on 8.6.6.19 and used razorclaw to root it. Then I have done the wipe data, and installed 8.6.6.23.
When I boot with Power and Vol- then Vol+ to enter RCK mode I get the green android guy with exclamation mark.
When I boot with Power and Vol-, then Vol+ I get 2 options: Wipe data and android cold boot.
I used some apps to test if the device is root and they say no.
Sorry for my english, but it's not my main language.
Any idea to fix this?

The 8.6.6.23 is firmware for the 3G model. You will not see OTA since ICS is not released for G model yet.
You can try to manually install 8.5.6.21. You could also try rooting and installing cwm recovery and flash the ICS ROM

Thanks for the answer. I've searched around and it seems that I can't get back to 8.5.6.21.
When I try to install it I get the android guy with exclamation point.
I guess I have to wait for ICS on 3G model

Easiest way is to root, install CWM recovery and flash an ICS ROM. Either the stock rooted ROM or one of the many custom ROMs

I was in a similar situation. The ASUS recovery did not work for me either and I couldn't figure out how to install CWM. There is not a lot of help for noobs with B80s and with all the methods out there it was a challenge to find the correct one. Here's what I did:
1. If you are not rooted, follow the instructions in http://forum.xda-developers.com/showthread.php?t=1427838 to get rooted. I had updated to the .21 firmware, and at that point, the nachoroot method is the only option. I had some trouble connecting ADB, but eventually I got it to work. This was the most difficult part of the process.
2. Install CWM. I was having trouble with this using the ASUS recovery, and I think it has to do with B80 models. I found the app in this thread http://forum.xda-developers.com/showthread.php?t=1346180 and it is amazing. If you are rooted, it installs CWM even on the B80 versions. The custom recovery will allow you to install any rom.
3. Download the option B ROM from http://forum.xda-developers.com/showthread.php?t=1514658. Place the zip on your SD card. This rom is the ASUS stock ICS firmware with root. Contrary to what some have said--I noticed a huge difference with ICS!
3. Backup all your user apps and data with Titanium Backup (optional). Do not back up system data, just user apps if you want to keep them.
4. Open your recovery. Shut the tablet off, and boot into recovery by holding down the power button and the volume down button until you are prompted to boot into recovery by pressing volume up. Pressing volume up should load CWM.
5. Wipe and then install! To wipe, select "wipe" on the recovery menu. Then wipe all data, cache, and dalvik-cache. To install, select install zip from SD card and find the zip file you downloaded in step 3.
Best of luck!

Hi,
may i hook in here, i've got a similar problem:
i TRY to get in adb mode, but it doesn't work as expected:
i used this thread initially (ASUS Transformer Root ToolKit V7.1 Universal (Windows) | 2011-09-22), i downloaded the toolkit, connected my turned off tab to the pc, booted via Power + vol up, it got connected to windows and i installed the drivers. so far so good. BUT: if i start adb server and use adb device, i dont get any devices listed... i cant do anything. And when i use this nvflash method with the download.bat file, i get an error and the usb connection vanishes... i dont have any further ideas what to do. but i can boot afterwards normaly to 3.2.1, though i dont get any updates
any hints? Thanks for reading anyways
thanks, DK
[edit] i have the version HTK75.DE_epad-8.6.5.21-20111216 installed [/edit]

What you did was put your tablet into APX mode. That's only good if you're doing NVFLash not ADB.
To use ADB just have yourtablet on like normal with USB debugging turn on

Hi,
thanks for your fast reply, you are right. i got my adb device id when beeing in the os, so this works. but, trying to use nvflash/Brk's Asus TF RootKit over apx, i got the initial connection, but when i want to flash it looses the connection or dies or something... no idea what
you got any hints how i can come back to a clean version, which is upgradable?
thx & best regards,

this is the program output btw:

[Q] Huawei u8500 HELP! Not booting!

Hello,
I have seen 1 thread that might help me under address:
http://forum.xda-developers.com/showthread.php?t=1320350
So basically I own Huawei ideos u8500 and wanted to flash it, but instead of editing flashbooting I clicked it. After this my phone does not boot past flash screen, what changed is that I get a notepad-font Android inscription between Huawei logo and Android, so the later just loads and loads again.
I'm noob with updating software, rooting or whatever. When I went into flash mode, I installed drivers for windows xp but the drive didnt appear there. I tried factory reset, didnt work, maybe rom update would work? I dont have clockwork recovery mod installed.
Any ideas how to get this done? Maybe some other way to reset stuff would help?
Thank you all for reading it

Hey,
I also got problems with PC... so I think I opened flashbooting.bat without flashing mode as my PC doesnt work...and my phone is screwed.
In flashing mode theres no new device, but when I open it normally and put usb I can see 2 disks (1 SD and 2nd Phone).
So basically I could install a new ROM, although I have no idea how. I need to put Clockwork mod to root file... But which disk?

Instruction: how I doing it.
for new users like me who wants to update or reflash half-bricked U8500.
first, boot ur phone to fastboot mode (vol up+red tube+power) - it looks like forever loading with huawei logo.
download drivers for U8500 and install
download CWM fastboot for U8500
connect phone to pc, wait for drivers installing, then unzip cwm and double-click install.bat file from admin.
now you should have CWM.
boot to recovery CWM (vol up+green tube+power)
then go to mount ----> mount USB with volume keys and OK button or with joystick
now your phone connected as USB flash device, put any ROM that supposed to go for U8500 (for example Cyanogen mod 7 or even stock rom) in zip archive to root of SD card, click to unmount USB, go back to top and click install update from zip file and choose your zipped ROM located on SD card. after completing click wipe cache and wipe data then reboot device.

[Q] Dopo D7020

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.

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.

You are not reading what you are typing.
Obvious answer: If you end up in the STOCK RECOVERY you simply do not have a custom recovery installed (Clockworkmod as you wrote). Get yourself a copy of a recent recovery from AndroidAndi's download repository (TWRP, Clockworkmod Swipe, PhilZ Touch), and flash the .tar.md5 of the recovery with ODIN in download mode.
Obvious question: How did you flash a ROM, other than some OTA Stock Samsung update on the device itself, in the first place when you don't have a custom recovery installed in order to do so?
EDIT: What exactly do you mean by "factory reset"? Did you re-flash your tablet with a Stock ROM? If that's the case, then any custom recovery you had installed was wiped and replaced with the stock recovery. Hence why you now don't have a custom recovery anymore.

Just to recap on the steps you should have done...
1. You downloaded the .tar.md5 of the recovery you want to install, from Android Andi's filehost, on your PC
2. You installed the Samsung USB drivers on your computer
3. You installed ODIN on your computer
4. You unplugged the tablet from the charger and powered it off
5. You took your tablet and HELD VOL-UP while you powered it back on (to get into bootloader mode)
6. You plugged the tablet in to the computer and waited for a moment while Windows was installing the driver
--- Here the story ends, according to what you wrote as you say ODIN does not find the tablet.
Well, are you sure you did the steps so far in that order? Can't be that ODIN doesn't detect the tablet when it's operational (read: no a total dead brick) and it's in download mode.
The ONLY problem possible: You installed Samsung KIES, and not just the USB drivers, on your computer. KIES interferes with ODIN. You need to exit ODIN, bring up the Task Manager (press CTRL+ALT+DELETE and select "Task Manager"), find "kies" and end the running process(es) - ignore any warning message.
If that's too complicated: Uninstall KIES and then find the "Samsung Mobile USB drivers" installation package ... with a bit of searching (just to assign some homework to you) you will the links right here in this forum section more than just once.
Once KIES is terminated, or uninstalled and just the USB drivers installed, start ODIN again ... now it should detect the tablet.
Once ODIN confirms that the tablet is detected...
7. Select the .tar.md5 of the recovery as the "PDA"
8. Flash the recovery. Once complete the tablet rebooted into the newly installed recovery.
As for on-device flashing. That's possible...
- Your installed ROM must be ROOTED (no root, no fun)
- You need Chainfire's "MobileODIN" (the free version from the Play Store would suffice), and you need to let MobileODIN install the "p311x flashkernel package" (I think with the free version you need to download it manually from Chainfire's thread and install it manually) - jump into Chainfire's thread and read on
Once you have Mobile ODIN installed it is just a matter of:
- Download the .tar.md5 of the recovery on your tablet once more (or transfer it over from your PC)
- Start Mobile ODIN
- Select the .tar.md5 of the recovery (should automatically be set as a "PDA")
- Flash and reboot into the recovery
However, as a fair warning ... as with every flashing of your device ... keep in mind something could go wrong (just to straighten it out that there's always room for user mistakes or murphy's law getting into the way ("Everything that can go wrong will go wrong"))

For future reference: keeping VOL DOWN UP held while powering on/rebooting the tablet takes you into the recovery in case you borked the system and selecting "Reboot" -> "Recovery" from within the _custom_ ROM's power menu is not an option (the Stock Samsung ROM does not have that option by default). Though keep in mind that this only works when the tablet is _NOT_ connected to the charger/computer ... when the USB cable is plugged in it seems to ignore the hardware keys.

Umm isn't recovery power and volume UP? At least that's how it is on my 7'' tablet and the 10'' I rooted and installed a ROM on.

Now that you mention it... yes, you're right jrc... "VOL DOWN" == Download Mode / "VOL UP" == Recovery (I failed to recall the "UP as in update.zip" association).
