What I used to root 4.2.2 was root with restore by bin4ary version 33 worked flawlessly with nothing extra needed this however was once I finally figured out getting the drivers installed..

Edit: as for the other two questions when I extracted the recovery it was the same file extension you mentioned but flashify still saw it and flashed it so I'm not sure about that..

As for the downgrading question I used the 4.1 backup with cwm already injected that was posted early on that came from htcmania I think. The trick with that is you have to extract it then move just the extracted backup to your existing backup folder and simply restore it in cwm recovery.. Highly suggest using tibu to freeze the ota apk once downgraded or you'll be ask to upgrade like every 30 minutes... If this is too confusing and all over I can do a proper write up if need be hope this helps
[General Questions and Answers] fipsy:
Exactly! :D

Press "Volume -" and then Power for about 3 seconds, then release Power and keep on holding "Vol -". I think you have to rename the file to "UPDATE.ZIP" on the SD-Card because Stock-Recovery only flashes updates with this filename as far as I know.

These are just apparently 10% after 8 hours of inactivity. As soon as you start working with the device you will normally notice an extraordinary drain. You may install Battery Mix for monitoring your battery performance over a longer time.

Try! I bet you won't get that far... :p
[General Questions and Answers] lvcongtou:
I have the same problem as you before,So I exchanged for another one.Everything was fine for a months.

Perhaps the update file doesn't contain driver files.I didn't find these files in the update file, such as:i2c,hardware,driver,sensor.

Hi ! I'm planning to buy this tablet and I'd like to know if its cpu is an a5 based or an a9 based quad-core : on the net you can't find much answer and some say that is an a5 based and other says that is an a9,like It's written on hannspree official site.

I'm looking for a good tablet with long battery life and no lag without spending too much money,do you sugest me this tablet ?

PS : I read about 4.1.1 and 4.2.2 difference in terms of permormance so I'd like to know if with 4.1.1 software everything is fine (battery,performance and connections)

MEDIACOM SmartPad 810c

ROM : First 4.3 (4.0.3)
[General Questions and Answers] fipsy:
If you are able to read german (or want to use google translate) you will find a lot of information about the CPU here: http://www.ainol-forum.de/ainol-novo-10-hero-1-i-2-ii/hero-2-ii-allgemein/p13005-welcher-cortex-a-ist-wirklich-verbaut/#post13005

The CPU is a custom production and cannot be directly compared to any other processor like Cortex-A5 or Cortex-A9. It's a kind of mixture of both. But the problem with this pad isn't the CPU but the quite poor GPU (graphics processor).

Definitely not. Wait another one or two years or invest 100$ more.

Yes, it is. But you cannot expect a turbo machine. The WiFi, Bluetooth and HDMI connections are okay in both Android versions. No problems with this. Even connecting to the internet via mobile connection (UMTS) is no problem with 4.1.1 if you are using a Huawei E1750 Surfstick on the USB port.
[General Questions and Answers] Bluze:
Well I decided to keep mine instead of sending it back. It seems to be working fine since it "came back to life".

Fipsy, I followed your instructions again after the OTA upgrade and all went well. I tried flashing SuperSU with the stock recovery, as I thought you said a few posts back that you can do that, but all I got was the "dead robot"...it failed. So I flashed CWM per your instructions and then SuperSU worked just fine. Thanks for all your hard work on this! Hopefully I'll have even a fraction of your knowledge one day!
[General Questions and Answers] fipsy:
Attention:

Due to an error in the CWM kernel (it's not my fault) there is an issue with the restore function in CWM Recovery. I cannot fix it myself. We have to wait for a new CWM kernel.

If you restore a full backup you will get the error message "Error mounting /emmc/.android_secure!" and the restore stops at this point. As a result the cache won't be restored and all Apps that were moved to the SD-Card won't work (that's what the .android_secure folder is for). But don't panic, there is a workaround:

After the restore stopped with the error message above first manually restore the cache partition from within CWM

Reboot the device into Android

You will notice that all Apps that were moved to the SD-Card are not working

Connect the device to your PC via USB and go on with the windows file explorer:

Locate the file .android_secure.vfat.tar.a within the CWM Backup folder

Copy this file to a new one named android_secure.tar and unpack it with WinRAR into a new directory

Copy the complete content of this directory into the folder .android_secure on the SD-Card of your tablet

Everything will work again

Oh, SORRY! I didn't give it a try with the stock-recovery - just with CWM. So if rooting with the stock-recovery doesn't work it would be necessary to first install CWM using adb shell.

I experienced something really curious today: I wanted to see what happens if I execute a factory reset with stock-recovery. After this reset all Apps were gone as I expected. But the rooting survived: The system partition isn't affected by the factory reset. Then I noticed that the clean 4.2.2 system had much more performance than the old system that was converted from 4.1.1. This wasn't surprising me. Then I restored the former 4.2.2 system using CWM. That was the point where I noticed the error described above. After I had finally successfully restored the system and restarted it I noticed that the restored system had the same excellent performance as the clean system before. And this was very surprising! The browser that was really laging before now works faster than ever. Also the boot procedure is much faster than before. I don't know how long this will last but at the moment it's a rocket. :laugh:

So this maybe a hint for others that suffer from a slow acting device: Perform a full backup with CWM Recovery, then make a factory reset with stock-recovery and after this restore the system with CWM recovery.
[General Questions and Answers] Bluze:
Thanks for the info. I just finished making my first backup with it, so good to know in case I need to use it.

Write up

A write up would be awesome. I am trying to revert to 4.1.1 and can't tell if I HAVE to root, or if I can use the stock recovery and flashify. Also, which image. I don't want to end up with no cameras, g- sensor, or worse, a brick.
[General Questions and Answers] HamBone625:
I'll do a proper write up when I get home but you do new root and cwm recovery..
[General Questions and Answers] fipsy:
If you want to use Flashify you will of course have to root! Look into the Playstore -> Flashify (for root users)

But meanwhile I would recommend what I told in my message above: Make a full backup with CWM, then flash the stock recovery, make a factory reset with stock recovery, restore CWM recovery and restore the backup you have made before. Since I did this my device is as fast and flawless as with 4.1.1. And even the power consumption declined to the earlier degree. I suppose that upgrading from 4.1.1 to 4.2.2 produces the problem! After this upgrade you should make a factory reset. Otherwise this update makes your device unusable. Obviously parts of 4.1.1 remain on the device that interfere with parts of the 4.2.2 system.
[General Questions and Answers] dmcrx7:
I have done a factory reset with the stock recovery and don't really have anything I need to bring back using a backup, so is this as good as its gonna get? It was never unusable, just slower. Should I just root it and add cpu tuner?
[General Questions and Answers] fipsy:
Okay. Are you really sure that your device is slower with 4.2.2 after the reset than it was with 4.1.1? Do you have any objective tests to prove that? Meanwhile I cannot confirm this anymore.

Rooting is always a good deed. :D CPU tuner will not do much as I suppose. It enables you to choose and configure different governors dependent on the battery status. It may save battery power but it won't make a compact to a racing car. :cyclops:
[General Questions and Answers] wyelkins:
My experience with the update has been entirely favorable. Before the update, I found the tablet sluggish and slow to react. Now, it is quicker. I must admit that I bought it back in December and have not used it much. So, there were not many apps loaded and very little data on the SD card.

When I got the Hanspree, I was a little disappointed with the performance but chalked it up to the $129 price. Now, it is much better in my opinion.

I just found this thread last week after I did the update and was very pleased to find it. Thanks to everyone who put in the time and effort to figure this out and share it.

I tried to flash the Supersu Zip in the stock recovery with no success. I never looked at the original recovery so I am not sure if this was modified also by the update, but it does seem different than described by the OP.

Recovery now has options to flash zips from internal or external SD and it will display and attempt to flash any zip it displays.

I tried flashing by renaming to update.zip but this did not work either. It unpacks it and aborts.

I guess I will have to flash CWM, which I have used in the past. I currently use Philz on my S3, but I have used TWRP.

I would like to install CWM using Terminal.apk but I think I need to do more reading. It does not recognize the su command. Is this because I am not Rooted? If so, then it is a chicken or egg problem since I am installing CWM to flash the root zip. Lol.

I need to read the whole thread again but any help will be appreciated.

Thanks again.
[General Questions and Answers] Bluze:
If you did the 4.2.2 upgrade, you should have root automatically. At least in ADB shell you should, I'm not sure about Terminal. There is no existing su binary after the upgrade, so just install the one linked in the first post following the instructions from fipsy.

I was not able to flash SuperSU with the stock recovery, but as soon as I installed CWM using cat in ADB shell per fipsy's instructions, it installed just fine.

Yes, read the whole thread, but the necessary bits are in the first post. Read it carefully...it's a little confusing as it started out with the original version then switched gears after the upgrade. I had to read it a couple times to get it all but I'm a little slow sometimes. :D
[General Questions and Answers] shouldbeshroomin:
Question: How to boot into stock recovery after flashing CWM? It just boots into CWM first and I didn't remove the stock recovery fix thing
[General Questions and Answers] fipsy:
I have about 70 Apps installed and about 500 MB system memory free. Nevertheless it runs perfect since I made a factory reset after upgrading to 4.2.2. Now it has a really excellent price performance ratio!

The recovery is being replaced by the upgrade from 4.1.1 to 4.2.2. The 4.2.2 recovery is different from the 4.1.1. Both recovery images are separately available for download here: http://xdaforums.com/showpost.php?p=49376465&postcount=204.

For this tablet only CWM recovery is available for now. You have to be rooted for installing CWM recovery. On 4.2.2 you are automatically rooted if you use adb shell. So first install USB drivers and ADB on your PC. And then with adb shell you can flash CWM as described in the first messages of this thread.

---------- Post added at 01:29 PM ---------- Previous post was at 12:55 PM ----------

You're right! Meanwhile it is really confusing! I noticed it by myself. It's because this thread maps the whole (stony) road from the first desire for being rooted to the successful implementation of CWM recovery. It's nice to read for a freak but not for someone who just wants to be rooted and use CWM. Furthermore changes between 4.1.1 and 4.2.2 made the thing even more confusing.

We should create a new description with hints for 4.1.1 and 4.2.2 and then Omegadrive should update the OP.

---------- Post added at 01:36 PM ---------- Previous post was at 01:29 PM ----------

After replacing stock recovery with CWM recovery you (of course) are not able to use stock recovery anymore! If you want to use stock recovery for factory-reset you have to flash it again (see my download link above). You may only use stock or CWM but not both!
[General Questions and Answers] Omegadrive:
I was thinking about it, but these days I barely have time to even read some posts, I'll see what I can do during the week.

In the meantime have to inform you that I did the update to 4.2.2 and factory reset of my brother's tablet and now runs beautiful, I'm having second thoughts about the sale now lol.

The only thing I noticed is that the clock speed can't get above 1008Mhz now, on 4.1.1 it did the same, but I changed the Interactive governor settings to have "boost" enabled and that pushed the CPU to get to the maximum 1200mhz, but now is not working. :(
[General Questions and Answers] b0joker:
Hello, I have been following this thread. And it has helped alot. Just thought id add this cuz you guys are telling everyone to factory reset after upgrade to 4.2. I just booted into recovery and wiped cache partition and dalvik cache. And my system is running sweet. And didnt lose my customized settings.Thanks for everything guys keep up the great work.
[General Questions and Answers] wyelkins:
Thanks to everyone for the replies. They have been very helpful. I have enjoyed reading through the thread and it really gives me a greater appreciation of the time, effort, determination and expertise that has been invested thus far in this device to enhance everyone's user experience. Wow!

I agree that it is confusing and that the OP could be rewritten to benefit new readers. They still should read the whole thread to get that feeling of gratitude and maybe also give them a desire to learn how to do these things themselves.. Hard to ask a guy to rewrite something for a device he does not even own anymore,. But, if you do, Thanks again.

That is another thing. Very few folks even hit the Thanks button, when they have been helped or learned some valuable information. OK, Sorry for the rant. Just a pet peeve of mine.

Fipsy, I have been following your instructions, but I am having trouble getting ADB to work. I have used it over the last 2 years on several laptops with XP and Win7 with various phones, Samsung Prevail, HTC One SV and Samsung S3. Having problems with the tab but it may be because I am now using an old Vista laptop. That laptop has had USB drivers for several devices installed before, which may be interfereing.

But, let me say that, I think I need to go back and try again, because I was in a hurry. I think there is a step that I forgot to do.

Tablet has been running great and I am starting to use it quite a bit now. Not really in a big rush to root it until we get some Roms to flash.

I think you guys have probably given me all the info that I need, I just need to take the time to do it.

---------- Post added at 12:49 PM ---------- Previous post was at 12:38 PM ----------

One thing that I forgot to mention. I bought this through Walmart in the US. From reading the thread I get the impression that some tablets were sold with a lot of bloat. I must say, that mine did not. Not really anything on here that I am wanting to uninstall like is usually the case with every phone I have rooted. I think that I noticed that after the 4.2.2 OTA that ES File Explorer was missing, but no big deal. I prefer to have apps installed as user instead of system anyway.
[General Questions and Answers] Bluze:
One thing to double check is that you made the change to the windows profile. My computer would not recognize it at all until I did that. Be sure to reboot after making the change.

---------- Post added at 01:32 PM ---------- Previous post was at 12:58 PM ----------

Fipsy, mine is running very slow now so I want to attempt what you suggested. Just to make sure I understand, first I download the stock recovery image you linked, flash that, and do a factory reset. Then install the su binary again, flash clockwork, and install SuperSU from the update.zip file. Does that sound correct?
[General Questions and Answers] fipsy:
*smile* I'm also very satisfied since I did the factory reset.

Did you use CPU Tuner to activate boost and change the clock speed? I suppose there are no "normal" governors anymore. Maybe they just changed their names because the three (new) performance options sound quite weird. Or maybe they now have another concept?!

---------- Post added at 03:25 PM ---------- Previous post was at 02:52 PM ----------

What does your device manager say before and after installing the USB drivers? Normally your device should be shown as unknown before the installation and afterwards as "Ainol Composite ADB Interface". Look here: http://xdaforums.com/showpost.php?p=48635635&postcount=62

I'd recommend installing CWM recovery because it gives you the opportunity to make a full backup of your system. Maybe this can "save your life" some time. :silly:

But integrating apps into the system ROM (e.g. with Titanium Backup) can save a lot of precious internal memory!

---------- Post added at 03:36 PM ---------- Previous post was at 03:25 PM ----------

Right. But you won't have to root again because the factory reset on stock recovery doesn't kill root. But you will need CWM to restore your system.

Perhaps it is also enough to just wipe the cache and clear the dalvik cache as b0joker suggested?! It's the easier way. So you may perhaps first try this before doing all the effort with restoring stock recovery and so on...
[General Questions and Answers] Bluze:
Thanks fipsy. When I get done with work for the day I'll try wiping the cache and the dalvik cache first and let you know if that works.
[General Questions and Answers] Omegadrive:
Used ROM Toolbox Pro and tried also with Trickster mod, it let's you select the governor and scheduler plus tweak the governor properties, tablet still has the same 4 governors as 4.1.1 but before I could enable boost in the Interactive governor, lower the clocks and then move them back to 1200 and that would be enough to stick through restarts, now it won't go up to 1200 no matter how much I play with the clocks.

I will try tomorrow with another app and see how it goes.

And btw, it does make a huge difference with boost enabled, on 4.1.1 my Antutu score was around 9.5k at default, with boost and clock working at 1200 it jumped to 11.5k+
[General Questions and Answers] fipsy:
Okay, 20% more clock speed makes 20% more Antutu score. :cowboy:

But does it really make a difference in everydays work? I mean the bottleneck is the GPU not the CPU score, or do you disagree?
[General Questions and Answers] Bluze:
I tried wiping cache and dalvik cache but it didn't help. Everything was very slow and sluggish. For example, loading a web page...the status bar would start, then just hang for a number of seconds, taking forever to load each page. Most apps opened the same way, very slowly. So what I did was make a nandroid backup, restore the 4.2.2 stock recovery, and factory reset. Then I flashed CWM again. Things are running great! About Device still reports 4.2.2 and I can mount RW with ES File Explorer, so I think I'll forget restoring the nandroid backup and just install the apps I want again.

Once again, thank you fipsy!
[General Questions and Answers] Omegadrive:
I think the GPU is fine, it even scores almost double the speed as my Motorola RAZR (my current phone) on every 3D test I have done, is the CPU that is lacking imo, almost all benchmarks is slower than my RAZR, which is dual core @ 1200mhz, only when I enable boost and clocks get to the top 1200 then I see a small improvement over my phone. People that are saying this GPU is weak are probably comparing it to more advanced phones like the Galaxy 3, 4, etc
[General Questions and Answers] fipsy:
Thanks for your test! So just wiping the cache is not always sufficient to "revive" the device. Good to know...

---------- Post added at 11:58 PM ---------- Previous post was at 11:46 PM ----------

Thanks for the information! While I'm just creating a new version of CWM recovery (6.0.3.3) based on the 4.2.2 recovery I noticed that there are some kernel modules not being loaded with 4.2.2. One of them covers CPU clocking. Maybe we can fix this issue as well as the missing internal support of UMTS surfsticks. But first I want to build the new CWM ... first things first ... ;)
[General Questions and Answers] fipsy:
A question to all CWM-users: What do you think? Should the new CWM recovery also backup the internal sdcard? This would take some time and space if the card is quite full. I'm not sure if this is reasonable because you also may create backups of the sdcard using winimage or other backup tools on your PC.
[General Questions and Answers] wyelkins:
No, it is easy enough to manually copy the SD card to an offline source like a PC or to manually copy the internal SD to the external. It would not be a feature of CWM that I would use.
[General Questions and Answers] Sparkrite:
No, don't bother Fipsy. I think you should keep CWM recovery as just that, a recovery method and not an integrated general backup util.

BTW Thank you very very much for all the work you have done on this tablet, it is very much appreciated.

New CWM Recovery v6.0.3.3

:victory: Here it is: The new version 6.0.3.3 of CWM Recovery for the HANNspree HANNSpad SN1AT71 (HSG1279)

Beside some minor bugfixes the main benefit of this release is that there are no more errors when trying to restore the .android_secure folder. So the "dirty" workaround to restore this folder is not necessary anymore.

The .android_secure folder is also automatically restored together with the data partition when selecting "data" from the "advanced restore" options.

BTW: Thank you wyelkins and Sparkrite for the comments! Following your suggestions I still omitted the sd-ext option which could have been used for the sdcard-backup.
[General Questions and Answers] Bluze:
Thanks fipsy! I'll try it this evening.
[General Questions and Answers] wyelkins:
The CWM that Hroark ported for the Samsung Galaxy Prevail used to back up an sd-ext partition on an external SD card. This was useful on this inexpensive phone because it had very little internal memory and we used the sd-ext to extend that. Backing that up was useful.

On this device, at this point we don't need it. Thanks for thinking about it and THANKS for the New and Improved CWM!

This Tab just keeps getting better!
[General Questions and Answers] fipsy:
I see! Thanks for the info! I also use this on my motorola milestone. There is an ext2 partition behind the vfat partition on the sdcard to source out user apps, libs and dalvik. It's quite similar to the .android_secure folder on higher android versions.
[General Questions and Answers] Satoooooshi:
Thanks for all the awesome work! My device is pretty snappy now and I'm definitely satisfied with it now.

Question though, how were you able to install 70 apps? I could barely install 15 without running out of space or having to delete something to make room.

In fact, I've only installed: Google Drive, Chrome Beta, Pocket Informant 3, Swype, the Amazon App Store, and a Tools app. Of course, I updated Maps, YouTube, etc when it asked me to, but I'm down to 553mb's now.

I'm in the US and have the Walmart variant if that makes any difference. On 4.2.2, already done a factory reset and cleared the various caches, and moved all the apps I could to the SD card.

Did you somehow increase the internal storage? Any help on this matter would be greatly appreciated! Thanks again for all your hard work :highfive:
