OTA upgrade on an new device will leave most Chinese text in place. It's best to do an clean flash
to remove most Chinese text and to set English at boot. Remove other apps at will and disable the rest.

(WM aka M Antutu 13600 Gbench2 1471)
It seems that the MK6589WM, aka M, has been used for the A820. Apart from the gpu on the standard MK6589 being clocked higher,
the performance will be just about the same for the qHD ips display, with the added power efficiency as bonus.

Only things that 'may' be missed on the A820 are a flash and a front camera. But the 8 mp bsi camera sensor makes up for it
by utilizing it's low light environment capabilities. Meaning less intrusive flashlight is needed.

Others versions of the model are:

A830, released early May 2013, is a 5'' model with flashlight. It is larger and comes with an 2200mAh battery.
specifications are the same as the A820 and has an slightly different casing (147 x 73 x 9.4 mm - 165g)

A830 Recovery <here>
Custom ROM V7_Jack44 (20130701)
MIUI v5 <here> (20130523)

A820T, again the same specs but It doesn't come with WCDMA 3G support, but is GSM/EDGE unlocked
and has an slightly different casing.

A820e, is the Qualcomm version using a Snapdragon 200 S4 Quad Core (MSM8225Q) SoC running at 1.2Ghz(?)
It also has an 8mp camera, has an Adreno 203 gpu and comes with an flash on the back. (Antutu 10910?)
Its not officially available for the western market but supports GSM/CDMA2000 1xEV-DO and has an slightly different
casing and higher price tag.
ROM's cn here and lenovohome
USB driver

Modded ROM : and
Streamlined version firmware A820e_1_S_2_002_0081/rooted(130513)

Official ROM :

S820, release May 13 is an other MTK version using a MTK 6589W Quad Core SoC running at 1.2Ghz
It has an 12mp camera with flash and front cam, also and 720 x 1280 pixels, 4.7 inches screen. 2000mAh battery and runs JB4.2.
Better specs come with an higher price tag, currently twice as much as the A820. It also sports an different casing in an variety of colors.
nothing at this time...

lenovo Ideaphone A800
( Antutu aprox. 6200 gbench2 1050)

A800, released early 2013 is the dualcore version with MT6577T running 1.2Ghz and an PowerVR SGX531 GPU
Currently(A800 has 512MB RAM) only supports Android ICS 4.0.4 and although it is an A8xx with qHD res. it
has slightly different hardware and has an different casing.(spec. 4.5'' IPS, 4Gb ROM,2sim, gps,bt4.0,sd, 5 mp(no flash)
Good low price device, bad community support. Rom developments, aside from lenovo, is weak and sloppy.

If you think this information is wrong, please let me know and I will adjust it accordingly.

Please note that Google apps are not really supported on MIUI
for the obvious reason that MIUI isn't officialy part of Google and there's
also is a lot of splintering in the MIUI ports branches for other devices.
That being said, try it out, it may work for your build.

If you find one that works let us know.

Been trying ColorOS on the A820 for an couple of day's now and I must say that it is an enjoyable experience so fare.
It's an bit of an minty flavor, if you know what I mean. It's Chinese but not completely which is an good thing.

To start, the ColorOS standard Oppo launcher is very well designed and has some sweet features. The camera page and
music page are very nice. The icon design is detailed and very consistent throughout the application. I runs very smooth and
also has an advanced theming engine with on-line support. It's all is an personal tast but having seen so many launchers over
the years I can say that the Oppo launcher is an visually well worked out and professionally build application.

There are lots of security settings in the ROM, which is always an big plus and something you see with lots of Chinese roms. And
though there are lot's of app's on the play store that do the same thing, it's nice to see it implemented as an standard feature with
the same visual style as the rest of the ROM. It adds to the overall experience.

And most app's in this ROM are nicely styled. Calendar, Notes, Files, Lockscreen, email etc.. have been fittingly redesigned to match the
ColorOS style. Sadly at this time some do not function completely on the lenovo A820.
There are still some bug's with this first port like the Camera, which works in taking pictures, but fails at recording video. The Video
app on the other hand is an advanced application in ColorOS. It plays just about anything it should, and adds some great on-line features
to it. For the moment only(mostly) Chinese contend but it all works great. So does the Music app which seems to be and advancement
to the lenovo music app you'll find on newer lenovo devices.
At the time of writing the the FM Radio doesn't seem to work in this port, which is a bit odd as it seems to work on most others ROM's.
Hopefully this will be fixed with the next update. It is an feature that in combination with tasker makes for an great alarm clock.

As for Google app's, they don't come preinstalled but adding gapps 4.2.2 seem to work just fine. And so do all other standard features
like 3G, Wifi, bt, Hotspot(wifi and bt!) etc..
It doesn't come with an standard browser, which is an bit strange, but installing one from the store is no problem.

I am not going to elaborate to much on this ROM, you'll have to discover it for your self, but as an brand experience this one does an
great job. lenovo may need to up there game on this. Nevertheless, we have this for our A820, so there you go ;-)

All in all It's an very consistent experience and, besides the current bug's, I would recommend it.

Now, lets get those bug's fixed so we can make it an featured post on slatedroid!

Problem is that you can not just transplant all lenovo modifications to an other rom, Staff1988i.
They did a lot of work to make it an lenovo experience rather then go for an stock android one.

I fear you will either have to install an prober lenovo rom, which I recommend, or make do with the apps in post #1
Or you could opt for MIUI an try to get your language in there. The MIUI rom is very nice.
Thanks.. Also i cannot instal a new rom..Says error.. i m going into recovery and then says instalation aborted...Thanks for help, anyway!

Some Tips to spice up you phone: (I'm not affiliated to any product!)

It's probably a goofy topics, but hey..

A thing that is missing in the box is an screen protector. An obvious thing to have.
Though some retailers add one as a gift, I didn't get any.. gifts.

So I order one that meets my needs and found the Benks HR series protector.
These seem really good quality products and at a reasonable price delivered.

Some info:
Made of high transparent material, further sharpened screen display, high transparent and ultra clear, <br />
great picture effects. Professional primary-color protection, clear and comfortable visual effects and rich color <br />
layer of liquid crystal surface. Scratch-proof, wear-resistant, easier to use, without hardness and obscureness, <br />
show the beauty of flowing rhyme.  <br />
Experience HR high transparency series protective film, and enjoy it in your own way.
Well, you know, thats gotta be great stuff :)

edit; and it is great stuff indeed. Very bright and scratch resistant quality item. Very recommended.

A Case:
Is an other thing that is practical in many.. cases. There mostly made rather bulky but some are of very slim form.
I was a bit hesitant to buy. So eventually I didn't get one.
Nonetheless I found this nice Chinese brand of cases, Nillkin, that's worth considering. They have an slim backcase in
there arsenal specifically for the A820. It's not all that perfect as I would like, but it's definitely one of the better one's out there.

For a case I would recommend it.

One of the advantages is that you can flip it on the front when you need to protect the screen.

Anyway I didn't get one.

What I did instead was buy an piece of transparent vinyl, with a carbon motive. Cut out what I needed.
And stuck it to the back. Best to opt for an decent quality for best stickiness.
Now my device has an structured look on the back that's also nice to the touch.
It think it looks great if I say so myself. Not worry about scratches at all.

Took me about 15 minutes of fun time.

Hi Ebsbow,

Thanks so much for providing this information. I am pretty new to android and am hoping to root this phone. I basically have no idea how to though. I've spent hours online trying to find the exact process but can't find anything. There are some Chinese forums with dozens of pages dedicated to it but are pretty hard to follow.

Would you please be able to provide an exact process as to how to root the a820? I see you've provided the root but I'm not sure what to do with it. Is it as simple as putting the zip file onto the micro sd and booting in recovery mode and selecting something there to get root access? One of the Chinese forums suggests so.

Do I need to sort out some kind of recovery software first? I'm use a mac if that is helpful. I see CWM is common but needs a rooted phone first. What about flashtool - that says it can be used to root your phone. I'm interested in following rooting the phone up with replacing the ROM with MIUI.

Sorry, I really am stumped by this and have already spent the best part of my day off trying to find the exact step by step info. Appreciate the help if you have time.

Many thanks,

Hi podgos, the procces has been simplified over the months you should be fine.

But you will need an Windows XP/7 machine or at least one running on Mac. If you have access to
one let me know and I will help you trough the processes.

Hi ebsbow,
Thanks for the reply. Yes I can get access to a Windows 7 pc. So if you could run me through it step by step, I'd very much appreciate it.
Many thanks,

Wow thanks so much ebsbow! That's excellent - it looks to be a really great, easy to follow guide. I will give it a go when I get the phone later in the week.

OK, no problem. I was going to make one anyway.
Hi again,
Just looking through the guide and thought I'd double check something. You say it's not mandatory to root the a820 prior to flashing the rom. This seems strange - but I assume it's the case. Would you recommend rooting first though? Is there anywhere in particular on the sd card that either the ROM or root zip files need to be placed for this? What do I select when I boot into TWRP recovery mode?
