[Q] Hannspree Hannspad SN10T1 recovery

Hello.
After recent acquisition of a Hannspad tablet i decided to install ubuntu desktop on it. Starting from the basics, clockworkmod was needed to be installed. As this tables is a replica of the gtablet , following this tutorial was mandatory. viewsonic-gtablet-for-dummies.webs.com
After installing clockworkmod from that tutorial for the 1.2 branch, i discovered that the softbuttons from the right side were broken, only buttons working for clockworkmod were the up/down (vol+, vol-).
So another recovery.img was neeeded. NVflash for nvidia tegra 250 was downloaded. When trying to understand the program, i issued the default command residing in a batch file, in the nvflash dierctory root " nvflash.exe --bct flash.bct --setbct --bl bootloader.bin --configfile flash.cfg --odmdata 0x3c000011 --create --go " ( still wonder why i did that ).
After this, the tablet became unresponsive, except for the apx mode. Only thing working was the power button. So i downloaded the bootloader for gtablet. After loading that bootloader, the tablet will start for half a second, but restart immediately. No recovery mode, no booting, just the backlights staying up for half a second.
My answer is, if anyone has any time and patience to help me and others who might encounter the thread, is there something that can be done to bring back the device?
Thanks !

yeah, you´ve 2 options : first you delete the partition and tell them you don´t know anything...
or install win 7/ or use ubuntu

Second option

I don't think that win7 can be installed on an arm processor. As for ubuntu, i will try to install it, but i have to learn more about the post/storage/arm cpu in order to bring the tablet back to life.
Can anyone direct me to some resources on how to install an os on an arm architecture?
I tried to find the resources, but in no avail.
Thanks .

hmmm .. im really interested in this thread.
i also have this tablet and i would want to try some different roms but dont see any support for it anywhere (for the tablet).
hope u manage to recover ur device..
ill be watching this thread .

okay it´s easy....
download the update 4789 etc. from hannspree, rename just update, take zip file(update) into root of your external device than boot ( push volumen up+ and power button 5 seconds) than should the system reboot with old settings, if nothing happens try with ac adapter and usb.
@fxandrei : i try to install win 7,bootlloader etc. if you know something or have honeycombfiles/updates etc. pls say it thx

Thank you, i will try as you instruct and come back with feedback.

good luck ..

@RootRightUser
i dont .
im looking for stuff like this.
im hopping that this tablet gets some support (like acer iconia or asus eee transformer).

Any news on it? I am on a worst scenario, the one where one decide to use nvflash_gtablet...zip on the Hannspad (modify partition scheme, and worst cbt )
I can't boot, or rescue anymore, and trying to recover the partition scheme seems to end in only APX mode to work (no more wolume up or down + power working)
Reflashing nvflash_gtablet restore viewsonic start screen but that's all...
I need a fresh and complete dump of hannspad SN10T1 (cbt+partitiontable+every partition dump)

For those interrested, with the help of people from slatedroid and forum.hardware.fr, I've been able to recover my tablet (not stock 12 patitions, but a good working 10 partitions images).
You can find instructions and the full package (rom 1.2.1-4789 + Linux and windows nvflash +drivers for windows + scripts) there:
I can't post URL so go to
www-DOT-slatedroid-DOT-com/topic/20148-hannspree-hannspad-sn10t1-rom-dump
For now, I can give you my Recovery for Hannspad (put you directly to 1.2.1-4789 Hannspree)
Instructions:
Connect your PC and Tablet with the usb cable
Put your device in APX mode.
APX mode is obtained, whe you have bricked your device, or when doing the following:
tablet is off and you start it by pressing and maintaining volume down + power button, it must power on and go to a black screen, it it goes to a freezed boot log or a work in progress image, the try wolume up + power button.
Linux:
You can see if your device in APX under linux by doing a lsusb, if you can see a line with:
Bus XXX Device YYY: ID 0955:7820 NVidia Corp.
So now you have a APX connexion with your tablet.
Download Recovery-SN10T1-1.2.1-4789.zip (link at bottom of post)
Extract it where you want, and execute ./nvflash_sn10t1.sh
After it is finished powerdown th tablet, do the opposite combo key (volume up or down + power for 3-4 seconds) and make a wipe data/factory reset.
You can restart, you have a stock rom (10 partitions only, not stock firmware)
Windows
Download Recovery-SN10T1-1.2.1-4789.zip
Extract it where you want
Now boot your tablet in APX mode:
APX mode is obtained, when you have bricked your device, or when doing the following:
tablet is off and you start it by pressing and maintaining volume down + power button, it must power on and go to a black screen, it it goes to a freezed boot log or a work in progress image, the try wolume up + power button.
Now connect your PC and the tablet by USB cable. Windows should search for drivers, it won't find it so you can cancel the windows update search. Now go to device properties (right click on computer and manage), and make it install the driver included in the zip. Now you must be able to execute nvflash_sn10t1.bat
After it is finished powerdown th tablet, do the opposite combo key (volume up or down + power for 3-4 seconds) and make a wipe data/factory reset.
You can restart, you have a stock rom (10 partitions only, not stock firmware).

many thanks
Thanks, that fixed the problem. Although the tablet is working, the quest to have Ubuntu on the tablet is still on the table(some pun intended). On slatedroid forum there are some folks with the exact same ideea, so, let,s hope that running x11/Ubuntu on sn10t1 will happen.
Typing the message from the hannspad.

Cant boot into recovery
Hello'
Am sorry if I have posted this in the wrong thread.
I have a 53 version Hannspad and I was able to successfully install Flashback 7.2 onto it.
Everything was well until yesterday when I installed Rom Manager from the market and installed Gtab flash recovery by choosing first option in the rom manager and then selecting Gtab from the list (the list had Advent Vega' Elocity A7' etc).
It said "flashed successfully" and I almost forgot about it until yesterday when I decided to install fards Gtabcomb 3.3_refresh. Now I am unable to boot into either CWM recovery or stock recovery. The tablet boots and runs just fine just doesn't go into recovery. It says 'Recovery key detected' and gets struck though I can boot and use the tablet. I am writing this using the tablet. My main probelm with Flashback is that it doesn't allow me to download apps via market.
Please suggest me how to get CWM back.
Thank you

Help please! My device wont enter apx mode... it does open the recovery mode every time and i can't make modifications because the side buttons aren't working aswell.

I thank everybody for there hard work to get these problems solved, I do have a good one :
I tried to flash Recovery-SN10T1-1.2.1-4789.zip and it excuted ok on my hannspad I saw the Hannspree logo, than the Tap N Tap running logo .. but now the Hannspad didn't startup, it came in a loop of the Tap N Tap screen, after 4 times the screen became blank (only the green powerlight showing) .
Now I read i had to do a Data wipe (go into recovery mode) .. but After (hard) reboot and pushing the +/- button it just goes to APX mode and no recovery (stock nor CWM) i just can't seem to nvflash any recovery.img to make the thing work ..
I would love to have some help, i would really appreciate it

Sadly enough there isn't much of a Hpad community @XDA, so for help with your problem you might be better of in the [email protected] forums or, depending on your language skills at android-hilfe or hannspad.fr. All three have excellent recovery guides. Good luck.

You're a lifesaver!

I thought I had bricked my friends Hannspad for good after trying many other "solutions" until yours did the trick. Thanks for being both clever enough to know how to solve my problem and kind enough to share.

[Q] What Tablet have I bought ? [ Also help with problem ! ]

Hello XDA!
I have a big issue here.
I bought a Tablet from Ebay
|
v
10" CAPACITIVE MULTI TOUCH ANDROID 4.0 TABLET PC ALL WINNER A10
http://www.ebay.com/itm/10-CAPACITIVE-MULTI-TOUCH-ANDROID-4-0-TABLET-PC-ALL-WINNER-A10?item=290721601261&cmd=ViewItem&_trksid=p5197.m7&_trkparms=algo%3DLVI%26itu%3DUCI%26otn%3D4%26po%3DLVI%26ps%3D63%26clkid%3D9104166066624506894
When i unboxed it the manual said the name was " N500-B " But i haven't found anything about that one either.
And the info about the " About Tab " is this
Modelnumber : BC1077
Android Version : 4.0.3
Basebandversion: 0.5
Kernel Version: 3.0.8+
[email protected] #33
Version: Crane_bc1077-eng 4.0.3 IML74K 20120407 test-keys
Problem is, that i haven't found anything about this pad, nothing at all.
And yesterday i think i ****ed it up real bad.
I installed CM9 from Slatedroid
http://www.slatedroid.com/topic/33373-rom-cm9-nightlies/
With this for wifi bt etc etc : 907c_compatibility_X.X.X.zip.
And obviously it's the wrong one.
My screen looks as if it was cracked and I can't see anything, i can't even access CWM.
What pad is this?
And is it possible to fix my problem.

Why did u install a ROM not made for your device?
Desire S • Fallout V2.0.0 • xda premium

Just been trying to search for you tablet i think it is a clone of Protab2XXL
Try this link it has an ics image and livesuite
http://downloads.poi...28-20120412.zip
then follow these instructions
Turn the tablet completely and starts in UPDATE mode.
This may be difficult but this is the easiest way to correct in update mode to get:
- Turn the tablet completely and then wait a second or 10 for the security for when the screen is the tablet is not quite ready to close.
- Press 'Home' and 'Power', and press up 1 times the reset button with a paperclip or toothpick.
- Keep your 'Home' firmly and let the 'Power' button and press it 5 times. (As the count-to-5)
If all goes well and the USB cable is connected to the PC, the screen remains black and now the tablet windows sees the new device in device manager. Also notice the sound message that windows does when connecting a USB device.
Run LiveSuite and select the Image from the Zip file and hopefully it will prompt you to Format your device and will Flash it with the ICS Image
or your can follow the upgrade instrcutions in this pdf

I followed this and all went well until i come to the step
" Now unplug the usb cable from the tablet and plug it back into the tablet.
 Wait a moment for windows to recognize the tablet. After this is done the following windows will appear.
 Press Yes "
When i unplug the cable and plug it back windows says " Usb not recognized " and in the device manager it say's " Uknown device "
So livesuit never starts flashing

bricked huawei g730

hello there,
I have huawei g730-u10
"MTK6582, quadcore cortex A7, 1GB Ram, 4GB Rom"
last week, I was trying to install a CWM recovery using "mobile uncle" app. after it finished , a prompt for restarting appears and I pressed "yes".
it was the last time seeing my phone alive!!! it restarts to huawei logo for about 20 seconds and restarts again and again and again....
unfortunately my device doesn't have a rom online, even on HUAWEI website, so, I downloaded a similar phone ROM "hdc-s5-gold" to use its preloader, cache, boot , etc
the problem is when I connect the phone to SP flashtools the red bar appears and then it holds for seconds and a message with connection loss appears while the phone is going in its infinite restart.. so the flashtools seems to find the phone for a while but fails to write to it thanks to power loss.
notes:
1. I have tried many flashtool versions
2. I have tried with and without battery connection, and with and without volume up holding.
3. the phone can't access to CWM, download mode or factory reset mode.
4. the drivers are installed shows: "MT65xx preloader" and I think there is no driver problem
5. even when I connect the phone to charger, it keeps restarting and the charging logo doesn't appear
I appreciate any help

SP log files attached
thanks

I'm not sure but i did find links for G730 official ROM.
There are 6 ROMs for this model, G730-U30, G730-C00, G730-T00, G730-U00 & more..
ROMs LINK
Then another link: Huawei G730-U00,Android 4.2,Emotion UI,V100R001CHNC17B137 Official Firmware
Seem's like there is stuff out there on internet, no offence. Just sharing information. Well, back to the bricked situation.... As i remember, there are methods to restore/fix semi/soft-bricked phone. Hope you find the solution. Search forum/internet.
I'm not an expert. Thats all i can share.

I have same problem.How to solve it.

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:

HELP! ROM Manager bricked my O3D - Is it fixable?

NOTE: Before we start, I have now googled it and in hindsight I probably should of left RM alone!
Anyway as the title states my O3D seems totally goosed! I selected the recovery flash in ROM Manager for P920, it rebooted and all it does now is show the logo for a second, vibrate then off. I tried the usual tutorial stuff...
Power button, Vol up battery in - it comes up 'USB Device Unrecognised' and then It also keeps popping up 'Unknown Device' however when I click on properties every entry is 'Unavailable'
Power button, Vol Down, battery in does nothing (tried it a million times)
If I do...
Power button, Vol up then apply the battery - Device Manager finds... 'LG Mobile USB Modem', 'MAP SMS' (Other Devices) and 'LGE Mobile Composite USB Device'
No sign of OMAP44xx so the flash tools don't see it... strangely LG Mobile Support Tool sees the phone and tries to update it however it says it has the latest firmware, when I use the update recover option it gets to 15% but then complains that it can't communicate with the phone.
Is it dead? :crying:
Any help would be much appreciated.

dont worry. its not dead. has happened to my phone a trillion times ..
all you need to is try as below:
1. without connecting phone to usb first hold down 3d button then volume down and keep pressing power untill it starts up and then off again , then release all 3 together as it is off and repeat (remember first 3d then volume down and then power). this time just let the power button go on lg logo but keep pressing the other 2.
2. if this doesnt work, then easiest method - download omap4boot for optimus v1.21 or all in one p920 v1.3 by XDA, remove battery, only press down the volume up button and while pressing connect usb. make sure you hear 1 ding of connect , 1 dong of disconnect then 2 dings of connect. after this the ding dong should end .. if you have all drivers installed , then it will install omap drivers. a window will pop up and everything will have a green check. once it does that you can install a custom recovery twrp or cwm using fastboot . boot into recovery and flash a rom.
still if doesnt work, have patience, post a reply and will tell other steps to proceed with .....

Thanks for your time RVBSD, unfortunately (although I will keep trying!)
In No. 1 - I get the first logo, but when I re-apply the 3D/V and power, I don't get the second logo.
In No.2 - I get the first ding/dong then just 1 ding, no sign of Mr OMAP! - I'll keep trying though.

Once u get the second ding and then this music stops, Open device manager. Look for lg usb modem and disable it. Then look for omap44 something. The device manager may be refreshing quickly. Somehow i had a chance to right click on omap device and chose update driver. Select manual and choose omap.inf from the folder that u have to download as per my previous reply. Restart computer and check again.
Alternatively you can install all inf manually, right click and install, before connecting the device.
Let me know
Sent from my LG-P920 using xda app-developers app

Again, thanks again for your input but I am still no further. I manually clicked the inf and it said it installed fine... but nothing changed in Device Manager. I then attempted to 'force' the driver on the unknown device, however after it installed it returned a 'Code 10' error... unable to start.
Even tried the service software 'LGNPST' but it couldn't even connect to the port! ho-hum...

i tried it again. even on my computer it didnt take the omap drivers this time.... strange .....
but i could install fastboot, then installed cwm recovery . then flashed a rooted rom and its working ...
1. Turn off your Phone, pull out battery.
2. download omap4boot-for_optimus-v1.21 (run "start_fastboot.bat" (it will wait until phone connected)
3. connect phone with USB cable without battery, the usbboot will start
4. insert battery while the usbboot is waiting, it gives 5 secs only
5. unplug USB cable the LG logo will appear with fastboot on top
6. download the attached files to your desktop and extract
7. open cmd and in cmd navigate to fastboot.exe location, where ever downloaded
8. run fastboot.exe from cmd and choose the cwm file to be pushed to your phone
command : fastboot -s flash recovery recovery-clockwork-6.0.1.9-p920.img
9. reboot device into recovery , try to wipe cache and factory reset and try to reboot
if this works it will take you to existing installed rom, then you can reboot to recovery and flash Su_Bbox_1.20.2_gazhead_signed.zip to root it
10. else copy a custom rom to sd card , insert in the mobile , reboot into recovery and flash the cutom rom

PLease help
CAn you tell me how can mount recovery partition

HELP Please; soft brick

Hi everyone.
Ok back in August I purchased an Oppo r7plus "m" version not knowing the difference, from a 3rd party seller. I know I probably should've waited until the phone would go on sale in Canada but I wasn't sure if it ever would. So anyways the phone worked great for a while. I noticed that it came pre loaded with OPPO Tools and Super SU. I thought wow, this phone is rooted right of the box? Great! So I started uninstalling some native apps of which I thought were just "bloatware", everything went fine until I uninstalled the weather app.
When I turned the phone back on after restarting, it now goes into the OS but continuosly flashes on and off and you can only access the dropdown notification screen. Luckily from there I can still access the settings menu. I tried holding the power button and volume down button to go to the factory boot screen. That worked and in there its says the color os version, but in brackets says
(rooted).
I can only assume the phone is still rooted but is stuck in some sort of soft brick. I've been doing alot of reading into how I might be able to fix the phone but I'm having trouble figuring it out. I'm good with computers and all but not to this level and I never rooted an android phone before.
Please somebody HELP.

So I've downloaded the ROM for my phone model, r7 plus m, and I transfered the zip file over to the internal storage of the device. I then held down the volume down and power buttons to boot to color os recovery. Than I cleared cache and install from sd found the zip file and it started to run.
After about a minute or two into the installation it stops and reads "Installation Failed". I'm thinking I need a recovery.img file but I'm not sure. Even if I had that file I don't know what to do next.
Anyone have any ideas?

Hi, how did you sort it? Are you still in need of stock recovery? I have one for model F, dont know if it works with M model.

1. Download and extract my RAR files ---> HERE
2. Open your PC device manager
3. Connect an usb cable only to your pc then press and hold the phone volume + button and then connect the usb cable to the phone
3. In the device manager you will see Qhsub_bulk then release the volume+ button
4. Right click on Qhsub_bulk and choose update driver
5. Use one of the driver folders which you alredy extract to install the Qualcomm driver and you will see it like 9008
6. Your phone have to be charged very well for a few hours before you try to flash it.
7. Remove it from the charger then connect an usb cable only to your pc.
8. Try to press and hold the volume + and power buttons at the same time for a few seconds and connect the usb cable to the phone.
9. You have to see the driver in the device manager like 9006 (you can release the buttons) [it wasn't easy for me so keep trying]
10. Open the MSMDownloader and press start
11. If everything is ok you will see a green progress bar flashing. (I was stuck here with the "NON-HLOS.bin" file which you can see in the "Other NON-HLOS File" folder inside the rom which you download)
12. When the process complete in about 10 minutes you can remove the usb cable from your phone.
13. Now you have to do a veeeeeeeery long press and hold on your power button untill you feel the vibration and after that you will see the OPPO logo.
14. Leave it for 5-10 minutes to load the Color OS.
15. Ok you have a working phone but still some apps icons that are missing and the keyboard doesn't appear when you have to write something.
16. Download THIS zipped ROM and put it in the internal storage of your phone.
17. Shut down the phone then press and hold the volume - and the power button at the same time for a while intil you enter into recovery mode.
18. Choose english and then install rom from zip file. After the installation complete reboot the phone and you will get a working keyboard and few more apps like Browser, Chinese market and else....
For me i still need to insert the IMEI's because they are lost... and now i have message: Oppo nv backup. The NV partition is invalid...
Good luck to all! And if you want to give me a beer: paypal: [email protected]
