Why on earth Sanei/Ampe released totally different products with the same model numbers, I'll never know. Surely a change in the processor make and model should have warranted a different product model number........

Anyway, hope this info is of use to you.

Yeah. The s2 is dual core and has bluetooth, which the Ampe85 dual doesn't. The pipo should be a good product and is due in this week. I just hope the screen is good. But it seems to me that the a10 processor is still adequate so maybe I should have gone for the n83. I have owned a cortex a9 zenithink e98 which was as fast as the a10 and pleasant enough except for the resistive screen and it's shortcoming in the video department.
What do you think about the a10 v. the rockchip 3066 for casual use. I hear that to open several tabs on the browser it slows down quite a bit on the a10.
Thanks for your views,

Hi ! New problem !!

I think I really got my N83 bricked, cos' since I applied the compatibility.zip, nothing appears on the screen AT ALL !!

I'm kind of proud, because I didn't find anyone with the same problem so I feel unique, but in the other hand my tablet is out of order, which sucks.

It happens yesterday, the battery was full and the only sign given by the device is that green light that you can see from the mic hole. If I play with the power button this light goes on/off like before but on the screen, there's still nothing.

I never managed to enter recovery without Novo7tools (is it REALLY possible to enter recovery mode with buttons ??) so I'm really stuck now.

I read a post somewhere written apparently by a chinese tablet's specialist and he says that in the factory firmwares are pushed in the tablets with a soft named PhoenixCard. I have to find a miniSD card reader to test this last-chance-solution... it's here => http://www.slatedroi...85/page__st__40

If anybody has an idea, feel more than free....

Thanks in advance.

dvigrli,

I'm guessing that you have the dual-core Ample A85 because as far as I know, this is the only one that has Android 4.1 (Jelly Bean) available.

If you do have the dual-core version of the Ample A85, then this is not the best place to be looking for information. This branch of the forums are for those with the Allwinner A10 CPU based products (rather than the RK3066 CPU which the dual-core has)....... However, if I can help you, I will do so.........

As far as rooting is concerned, you'll need to Google RK3066 Android 4.1 root for a possible solution.

I don't know how you can make a usable backup copy of your current system rom. Ampe will eventually release the firmware you have installed and will post it on their website. But, trying to downgrade from JB to ICS will probably create more problems than it solves. Almost certainly, if Bluetooth is not working in JB, then any version of ICS you try, it still won't work. - are you sure that there is Bluetooth hardware in your tablet?

Dave


I appreciate your response.
True, my tablet is a Dual core RK3066. Then look for the most appropriate fora.
Regarding hardware, I know if you have bluetooth. All the tests I've done show that it is not.

JohnC

You're correct in thinking the browser slows down with multiple tabs open. I have heard that using a non-stock browser (such as Opera or Dolphin) these problems don't occur as much and browsing is much faster. A lot also depends on which version of Android you're using, Gingerbread was awful for browsing, ICS is better and JB is even better.

Comparing Antutu benchmark scores for the two processors shows that the Rockchip RK3066 is about 1.6x faster than the Allwinner A10 (around 4750 for the RK3066 and 2930 for the A10).

As I said previously, I've never used a RK3066 based tablet, so I can't comment on how good/bad it is. But assuming that it doesn't cost significantly more than the Allwinner A10 based tablet, I'd opt for the RK3066 dual core for the following reasons:

1) It's a newer processor and as such is more likely to be supported by the manufacturers.
2) It's faster.....
3) It already comes with Jelly Bean installed. Who knows when (or even if) JB will be ported to the older products - I've only found JB officially ported to one Allwinner A10 based tablet at this time.

However saying this, both have the Mali-400 GPU and as such have the same limitations in terms of processing video/graphical data. From my experience this is one of the main causes for these browser issues (OpenGL is crashing for various reasons).

I'm quite happy with my Sanei N83 Deluxe tablet since Ampe/Sanei released the upgrade to ICS. Yes the browser slows down ever now & then (but I do have around 14 tabs open at once - lol).

Hope all this makes sense to you and is of help to you in your decision.

Feudjay,

From what you've described, you haven't bricked your tablet, you've just managed to change some settings which stop the display from working.

OK, by far the easiest method to recover from this is to use the PhoenixCard method (I posted full details of how to do this further up in this thread). If you haven't got a micro SD card reader, you can always use a regular SD card reader along with the micro SD to SD adapter that usually comes with the micro SD cards.

The other method is using Livesuit.

1) Start LiveSuit.exe, confirm installation for drivers when asked.
2) You should see a welcome window. Just click the “No“ button.
3) Click "Select Img" button on the left to select the downloaded firmware
4) Turn the tablet off and disconnect the USB cable.
5) Press the following key combination to start the upgrade on the tablet:
5a) Press and hold down the “Vol +” on the tablet
5b) Connect USB cable to the computer
5c) Just as soon as you connect the cable, start rapidly pressing power button for about 10 times
5d) Keep holiding the “Vol +” button until the LiveSuit window pops up
5e) Once LiveSuit window pops up, you can release the “Vol +” button

If LiveSuit window does not pop up, repeat steps 4 and 5.

6) You should see a dialog box to choose mandatory format. Select Yes.
7) Confirm that you want to force format by clicking Yes again.
8) The upgrade begins and should take about 3-5 minutes.
9) Wait until the dialog box appears showing that upgrade is complete.
10) If the tablet does not start, use the power button to turn it on.

I've never used Livesuit myself, I prefer the PhoenixCard method as it doesn't need the messy button pressing - which I've heard from others doesn't always work every time. So these instructions have been 'lifted' from my tablet suppliers' website.

Hope this helps you get your tablet operational again.

Thanks Dave for addressing my concerns so well. That sounds like a nice tablet.
The fact that dual core are not that much more expensive kind of moots the issue of the quality of the N83. However, I bet it's lighter and much slimmer than the Pipo S2 (which I'm expecting any day) so I will keep open the possibility of trading for the N83.

Hi Dave,

I just see your answer, I'm travelling right now, far from my tablet...

I'll be back on wednesday and I'll keep you posted, will try the Live Suite method first as you adviced.

Whatever happens, I have to say thank you for helping people like you do, I've read a lot of posts on this forum and I have to say that I'm very impressed !!

Talk to you soon.

Jeff

Anyone know how to open an A85 to look inside? I broke the screen inside.....


Ramjali,

It's 'fairly' simple to open. Firstly, get yourself a old credit/bank card and 'sharpen' one of the edges using sandpaper or a sharp knife (just to make it thinner). I use a plastic bank card rather than a screwdriver (or some other object) as the plastic is less likely to scratch or mark the trim or casing.

  • Make sure you've powered OFF your tablet.
  • Remove any micro SD card you might have.
  • Place your tablet on a cloth on a firm surface/table with the screen facing down.
  • Insert the corner of the prepared card in between the metal casing and the outer trim and gently ease the outer trim away from the casing, working your way around the whole of the tablet. I find starting at the hdmi/sd card socket is easiest. The trim is held in place by a series of tabs which lock into the case, so by being careful, you shouldn't break these tabs.

If you have broken the screen, it's probably cheaper to buy a new tablet than a replacement screen (if you can find one). Remember though, that you could always get yourself an hdmi cable and just use the tablet as a video player if you link it to a tv. You'll probably find that while the screen won't display anything properly, it will still work for the 'touch' functions.

Regards

RokSiEu,

Have a look at post(s) #48 & #50 on page 2 of this thread. I've posted instructions on rooting there along with the files needed. Just a warning, there are several versions of the script floating around, the one I posted works, some of the others don't.

Let me know if I can help further.

I have rooted my A85 and then installed cwm_recovery_6.0.1.2_a10 and now when I go to recovery I see android with red triangle in it. When I press volume key I entered recovery and I didn't have "apply from zip" and I choose "apply update from external" and flashed cm10_a10_20120913.zip . Then I rebooted and now my touchscreen isn't working. I tried to apply (using apply update from external storage) gapps and n83-deluxe_compatibility_1.2.0 but I get "e:signature verification failed" for both.

What to do?

RokSiEu,

I've never tried installing CWM10 or AOKP, so I don't know how to get CWM10 working properly.

The reason I've never tried is that there is no Bluetooth support (and never will be) in CWM10/AOKP and I need Bluetooth.

You should be able to easily restore your system back to one of the standard factory ROMs by following my instructions in post #106 (on Page 6 of this thread).

Can I ask, why do you want to install CWM10 on your tablet? - Most of the original reasons for installing it were removed when Ampe/Sanei released the official v4.04 ROM. Can you also let me know exactly which Ampe A85 you've got (Elite, Deluxe, or Dual core) - It's possible that CWM10 won't work on your system at all.....

I'll do my best to get you back up and running.

Dave

Hi Dave,

since I'm using Windows through Linux via VirtualBox, it's hard to believe that the LiveSuit method will ever work (never got the button combination trick to work, now or before !!)

I just ordered an adaptater, I will wait for it to complete the PhoenixCard method that you described before.

Again, many thanks for your help.

RokSiEu,

Here's the latest version of the Ampe A85 Deluxe firmware (Android v4.04) -> Ampe A85 r4.0.2463

It's the version I'm currently using on my Sanei N83 Deluxe and Livesuit is included in it.

BTW from reading previous posts in this thread, it would appear that your 'Android with a red exclamation point on it' indicates a low-battery state. Charging your tablet for several hours 'should' resolve the problem.

Thank you.

I've run LiveSuitPack_version_1.09_20120301.exe
1. I get language selection screen (I choose english)
2. drvinstaller_X64 Shows up InstallRootEnumeratedDriver message with only OK button (I click OK)
3. message shows up "add device fail!" with only OK button (I click OK)
4. nothing happens


Then I tried to install phoenix but it's all in Chinese and when I came to end of installation progress bar went back to start and program was NOT installed... I don't know why (don't understand chinese but I think it's like the rest of the software (next,agree,install,finish), but it isn't I guess.


Wooohooo, the issue lies in windows 8. I tried with windows 7 and it went smooth!

Damn, there is no "settings" icon so I can't change nothing. Everything is in Chinese :(
Also I can't connect to wifi and nothing... here's error(or something) showing up when I click on wifi icon

FINAL EDIT
everything works after rebooting the tablet :)

Yes everything is working now, including bluetooth!

One question tho, did you find a way to spoof device as nexus 7? So that all apps would be available in play store? Tasselhof script doesn't work for this.
