I've read that Sanei N83/ Ampe A85 with rk3066 chip has some battery issues. It seems that Sanei released a firmware atempting to solve those battery related problems.

You can find it here: http://www.szsanei.c...own.asp?id=1004

If you test it, please let us know. I'm going to buy an N83 as I found it very cheap on banggood and it's nice to know the tablet will work as i should.

Which firmware is this ?
I am running the 4.1.1 Sanei N83 but I need to downgrade to get ROOT since I could not find any root option for the 4.1.1 version.
I hope this wont affect battery or other options, 4.1.1 is perfect as I see other than the fact I cannot root.

Any idea ?

I think it's 4.1.1 with battery fix. Have you tried zhuodashi to root?

Thank you for posting. However I cannot trust you having just one post and providing a link for a software that could potentially brick my device.

rkbatchtool doesn't verify *oops, so you can flash wrong firmware. If the tablet is bricked, you can reflash it, but you have to open it and desolder battery and maybe use rom mask.

Here is the link for last official firmware:

https://mega.co.nz/#!bMYXXY5A!Cyqw5XwuwHS6CrrXbbrrWAElPWN4LzIU-D3fhzQBIus


It took me 10 hrs to download as sanei's site is very slow, so I am uploading to mega for all who need it.

Note: I've just got N83 since two days ago. I will provide a detailed review for it, and a review for the site I bought it from.

I am also an experienced developer and I am even thinking even of porting cyanogenmod CM10 and CM10.1 to this device if I have time. Currently I am porting CM10 and CM10.1 to LG E400.

Thank you very much for your upload it was really helpful because sanei's servers are really slow!!!!

Could you please tell me how to upgrade my tablet with this firmware? In the 310.zip there is a folder with RKBatchTool, which cannot recognize my tablet when I connect it. I using windows 7.

Power the tablet off, insert usb cable, hold power + volume up keys and windows should detect the new device and add drivers for it. If it doesn't add drivers, open device Manager, use update drivers and point to the directory with rk drivers.

Update Manager says the best driver is already installed. Adb fastboot and livesuit recognize my N83 but rkbatchtool won't. Can you help me flash this firmware, I'm stuck in boot. Because I installed what was apparently an incompatable CWM recovery.

Just do what I said. You need a different set of drivers.

Hi there, I have my Ampe a85 for about two months now and I' m a total noob (first tablet). I'm thinking of using your prescription neuro to root the tablet. build number is RK_anpei8am-r4.0.51-20121207. I'm generally pleased with the tablet, the only drawback is the battery time which varies from charge to charge. Only two times in those two months it managed to reach 5 to 6 hours! (with Wifi constantly on). Wifi had issues at the begining (low signal) then i thing was getting better for some reason! since I changed rooter is much better now.

I was not looking at this post for a long time using my new and fully customizable u30gt, but after a while i told myself, let's see what's happening. I looked at a post by neur0 on slatedroid (thanks) and i saw sanei had published a last firmware. Gently it is upped on mega.nz, imagine what i've done! My n83 was linked to my tv set with an external mouse and i used it as an android tv usb device, but i told myself: let's see this firmware.
THIS FIRMWARE WORKED, RESETTING MY TOUCH SCREEN AT NORMAL VALUES!!!!!
Here is the firware, it is indicated as 310.rar and in rockchip batchtool fw time appears to be 2013-03-11

https://mega.co.nz/#...LzIU-D3fhzQBIus

Unfortunately it's not rooted but this is the minimum following my guide, when i've some time i'll surely try.
This one someother uploaded, not working for me https://www.dropbox....83_root_cwm.rar anyway it does not brick your devices

Yep, you can used my rooted fw if you need to root the tablet. Since it's based on last Sanei fw, I'm curious if battery life will change for better. Can you please tell us if battery life changed after you update the firmware?

I'm only getting 4hrs of constant browsing with wifi and screen at 50% brightness. But the router is like 30 meters away and I have 4 walls between me and the router.

I followed your instructions and the tablet is rooted! Thanks neuro. I got 4 1/2 hours of browsing -50% brightness, which is great (I used to get around 2 hours).
