so part one will backup my system as it is now? and not the out of box state?
and i would love to contribute, but that post might as well have been in chinese, way over my head unfortunately! but i thank you for the hard work to help the rest of us out!
Yes, part one and part two in the case of someone who has used their tablet for a while would back up in the current state.
The guide, while useful for everyone to be able to backup their tablet, is designed for people who have just bought the tablet and thus getting a nice clean OS backup made for sanity's sake.
If all goes well in its creation then yes, but it's always better to trust your own backup over someone elses, which is why it's a good idea to backup as soon as you get the tablet (hence the guide). I myself didn't know of nvflash backups, so I fell into the trap that I'm trying to save others from.
First of all, can I just offer my humble thanks for such a fantastic piece of work for an android noob like myself. Perfect.
I'm having the same problem with the 'backup' download though? Makes it to a couple of megs, says it's done, then when you try to extract - even using 7zip - it tells you the file is broken.
Any help gratefull received. I'm slowly trying to pick my way through things to get the most out of this tablet.
While carrying out Part 1, seems to get stuck transfering partion 14. Have to close command line & then end up with a file size of 108,800KB for part-14.img. Does that seem ok or has something gone wrong? I have stock 1633 model.
Cheers.
Edit: Just read that partion 14 isn't restored, so not worrying too much. Have CWM back up saved as well.
Thanks again, great help! (Better safe than sorry!)
I'm currently in linux so can't help much with windows 7zip issues, but all I can suggest is trying a download manager to download the attachment such as freedownloadmanager.org or if using firefox I think its called DownloadAll (bad that I use it and cant remember the name).
From what I've read, if it gets stuck then it means you have a bad section of flash on your storage, and you'll just not to be able to backup part14.img (which most of the time doesnt seem to restore anyway).
Many many thanks for this thread!
It helped me come back from an almost bricked tablet!
I has installed HannsTitan-v0.2d on my tablet and it worked great for a while.
But once it had been turn off by holding the power button down too long, and then turning it back on, I got stuck on the Hannspree startup logo.
I could not even boot to the recovery mod!
But after running the restore, I was able to get manufacturer recovery (as it overwrote the custom one) and then was able to rerun the rom installations!
I'm still amazed at the amount of people who just flash other devices roms without knowing how to roll back if it goes wrong - or just plain flashing and hoping

Well can't say I wasn't one of those who knew about flash etc, I mean coming from windows I knew the first thing to do myself was to backup my partitions, which I did in CWM - had no idea about the whole flashing business till it all went wrong. If it hadn't been for KickIn and his viewsonic based rom I'd have had a brick myself thanks to trying out flashback and then reverting to tntlite.
Needless to say it's all your fault for making tntlite so good I wanted to go back to it
getting an error on mine when trying to backup the partitions, it is completing 2-8 then failing on number 9 and stalls there. I have only just received the tablet, i have switched it on and there was a new update that i downloaded. not sure if this is why it now wont backup using the info on the first thread. The error is below
Nvflash started
[resume mode]
failed executing command 15 NvError 0x120002
command failure: read failed (bad command)
bootloader status: unknown operation (code: 1) message: flags: 0
Any help appreciated. rebooting and trying again does the same thing, halts on number 9, this is the 53 tablet for info.
Thanks
i have managed to get the CWM recovery image (modified by roebeet) working, this has now enabled me to do a full backup which is good as needed something to go back to if all goes pear shape.
Thanks
