I ordered MY UMI X2s specifically from this seller on aliexpress, the unit description states 900/2100, additionally, in the checkout I specified in a message to the seller that I wanted the 900/2100 unit.

On aliexpress you will find a few vendors that sell it listed as 900/2100 but most sell it listed as 850/2100.

This particular page, which seems to be somewhat official states that the one they are selling is 900/2100.

When i received my two units, the packaging material stated 900/2100 and works as expected. Here is a picture of my packaging. picture.

The dual sim slots work like this;

When you have only 1 SIM in, it is like a normal phone, everything works (wcdma and gsm), regardless of the SIM card slot.

When you put a second card in, SIM slot 1 becomes WCDMA/GSM and slot 2 becomes GSM only.

How did I get 850mhz to work? I just put in the sim and it worked, no fiddling or anything. It was a telstra "next g" sim.

How did i know what frequency I was on if i didn't set it in the engineering menu? i used this website and a spectrum analyser.

You are a Champion

WELL DONE, THANK YOU for your quick & articulated reply....you really know your stuff.

I guess it's a toss up for me where to buy from the seller you suggested is the same price as Merimobile IF I get it delivered by DHL for the 2G RAM & 32 ROM Version.

One thing I like about Merimobile is that I can use PayPal should there be an issue etc They replied to my email about ETA and their answer was Monday.....wait and see

One thing I forgot to ask about was Does the GPS does work well here in Australia?....... I recall reading someone's comment that it didn't work too well.

Have you had to install firmware updates for bugs etc as you would with for example router & other hardware etc

BTW ...connecting to the internet Does it have good range and speed as it is stated as working only in b & g draft, which is good if you are near an Access point, I noticed the X1 had n draft so maybe the X2 really does have n draft but a typo etc

This maybe hard to answer as its too soon to tell But in regard to Operating System Upgrade do you think this device is capable of upgrading to future Operating System eg Jelly Bean 4.3 in the next couple of months and Key Lime Pie 5.0 at the end of the year.

Again THANK you

Thanks bgdwiepp. We have AT&T 850/1900 network and a lot of MVNOs on AT&T network in US but AT&T has no 2100 band. I am puzzled if two bands really required for decent megabit-scale speeds (like with Tmobile) or just one is enough?
[Android General] Animal_Chin:
Was finally able to unbrick my phone thanks to bgdwiepp's suggestion to use shuame. After fumbling around for a couple of hours I managed to hit the right combination of buttons and shuame popped up on my phone and gave me the option of installing a custom rom from the external sd card. Woot!
[Android General] S4X:
By the way what your packaging says about 3G - is it 900/2100 or 850/2100? Or even just 2100 i have seen too?
[Android General] Animal_Chin:
packaging says3g WCDMA 900/2100MHz
[Android General] bgdwiepp:
Glad you got it working! It seems like a very good/powerful tool, but being in chinese is really quite a bummer :(

Used UMI X2 to sell...

If anybody is interested in buying an unpacked and 2 week used UMI X2 (4x1,2 Ghz / 2GB RAM / 32 GB ROM) from Germany, please contact me for further discussion.

It's been tested for 2 weeks and the only issue i found was a not working vibtation motor. Everyting else seems to work fine.

(As I won a SGS4, I've got no need for it anymore :) )

If I violate xda-rules with this offer, please forgive me!
[Android General] S4X:
Pandawill shows that their phones have 3G 850/2100.

Well, unless both 850 and 1900 are needed for AT&T network to run on 3G that could be a reason that it did not work with StrightTalk. If just one band is sufficient and bgdwiepp claims 850 is still there even not being listed then i do not know what is causing the problem not having 3G

Did you try the exchange?
[Android General] Animal_Chin:
Not sure what that is...
[Android General] S4X:
Return and exchange the phone with one which explicitly says 850/2100. You may claim that you have got not what is listed on the website
[Android General] Animal_Chin:
Too much hassle for me...

seems like the way some people are talking 850 is probably active anyway. I need to find those settings on the phone that tell me...

From what I've read online you do need both 850 and 1900 for 3g to work. That's just what I've seen people say on other websites though, nothing concrete.
[Android General] bgdwiepp:
AT&T only require one or the other, at any given time to establish a UMTS connection, unlike T-Mobile requiring 1700 and 2100 simultaneously. Eg, AT&T is 850up/850down or 1900up/1900down opposed to T-Mobile being 1700up/2100down.

This shows the AT&T coverage of the 850 and 1900mhz bands seperately circa 2008, however this offers no garantees.

Open mobileuncle tools on your phone, choose engineer mode, then engineer mode (mtk), in the "telephony" tab, select "band mode" and then select "sim 1", that will show what bands are"supposedly" enabled.

Also, if you type *#*#4636#*#* into the dialer, choose "phone information", then press the menu button and choose "select radio band", to see what is available.

Additionally, I am curious as to your baseband version? should be visible under "about phone" in the settings menu, starting with "MOLY"
[Android General] Animal_Chin:
ok, well, interesting results maybe you can help clarify them:

under gsm mode:

egsm900

dcs1800

pcs1900

gsm850

under umts mode:

wcdma-imt-2000

wcdma-pcs-1900

wcdma-clr-850

wcdma-800

wcdma-gsm-900

baseband version:

moly.wr8.w1248.md.wg.mp.v7.p1, 2013/04/10 00:39

If the map you had is still accurate it explains why I have no 3g. No 850MHz band in my state.
[Android General] S4X:
Yes, looks like you do have 850 band in the phone. This should work in US. Are you sure you don't have 850 in the state? AT&T 850 is covering whole your area pretty densely.

Hey. So I'm slowly moving towards buying a UMI X-2 Turbo from Aliexpress and I'm curious if anyone else is looking for a phone right now - are there any good alternatives at a similar price and at 1080p/2GB RAM/ 1.5Ghz(+) Quad Core specs?

Or is this the definite phone to get.
[Android General] Chucho72:
Umi X2 doesn't start

I'm in the same position as you were. I see Android on the phone and it doesn't start.

What did you exactly do to get it running again?

---------- Post added at 09:51 PM ---------- Previous post was at 09:09 PM ----------

If I connect a SD CardI can only get to the internal SD card from recovery, the 2nd SD Card is not selectable.
[Android General] Animal_Chin:
First thing you have to do is install shuame on your computer.

The trick is to push shuame to your phone. Once you do that you will be able to go into the shuame recovery menu much like the factory recovery menu except it will have the option to install from external sd.

I have no Idea which button combo I used but It seems like I had to use the volume down and power button to get it into the menu that shuame liked.

Like I said it took a coupe of hours of fumbling around before I was able to get it to work. Hope this helps a little anyway. Just remember it is definitely possible!
[Android General] Chucho72:
Do you have a link to the CWM 6.3 recovery. Don't seem to find it, probably looking in wrong place

To what extent do you think dozens of Chinese sellers on Alibaba are trustworthy offering grassroot prices but asking to pay only using Western Union or bank transfer?
[Android General] Chucho72:
Well, my problem is my Umi X2 is hanging on the splashscreen.

I tried everything I know to flash it again. The recovery screen in the Umi X2 only lets you do UPDATES of the system, not full zip installs.

I think I'll give up and return it to China.

[Android General] S4X:
It is pity to realize that there exist only one single user of this phone per whole US and this users is living in the area of possibly no 850 support..

Can you call and ask AT&T tech department to tell *exactly* about 850MHz support in your area?

[Android General] Comp1demon:
I am on at&t too. Customer service says 3g in my area is 850MHZ. SO I really want to get a chinese android phone.

I was looking at the UMI, Zopo, Xaiomi and iOCean.

iOcean is out of the questions as 850 is there but does not work according to those who tried it and on at&t it doesn't work at all pretty much.

So it comes down to the other 3.

What is the at&t users experience with this phone?

Working well?

Does at&t detect it is a smartphone and tack on a data plan. I read many other forums that 99% of the chinese phones will not register on at&t and a thread that was updated as early as yesterday claims he has a UMI and a ZOPO on his at&t plan wifi only and it's been close to 6 months now with no issues of a data plan getting added.

I really want a good 1080p phone for my line that has no data plan to use wifi only.

UMI the way to go? Thoughts?
[Android General] Lawk:
Does UMI provide OTA updates for the X2?
[Android General] chronic8000:

[Android General] anasahmad17:
Hi guys,

I got my X2 3 days ago.. i was having a lot of problem with both 2G and 3G data connection.. it just wouldnt stay stable..

whatsapp was crashing upon startup and wifi was a total mess.

I did a factory reset yesterday in desperation.. Whatsapp started woorking fine after that but netowkr problems were there.. i left my sim in the phone and let it download random stuff whole day, also installed this app called netowkr booster..

By nightime my 3G was stable somehwat i was gettin H+ speed.. 2G is working totally fine now.

For wifi i downloaded fasterfix and it has improved it so much..

Overall i am very happy with the purchase as of now.

Was pulling my hairs three days ago :D

And its 1.2ghz 2Gb version.
[Android General] ohagas:
How did you fix the 3G?
[Android General] chronic8000:
I found on my x2 in the UK GiffGaff an MVNO of o2 Telefonica couldn't hold a 3g signal at all, neither could t-mobile and the only network to hold a constant 3g hsdpa / hspa+ signal was 3. It seems like a baseband issue but trying to get hold of someone from Umi to fix the issue is going to be difficult at best. Wonder if someone in the XDA community is good at updating basebands?
[Android General] anasahmad17:
I used this app Network booster from the Play Store and set my connection on WCDMA mode only from settings.

After that i let it download 10-15 apps and a movie.. it was very slow at beginning but with time the stability and speed improved.

I think UMI comes with Quad band support on GSM and dual band for 3G.. From where did you bought it?

There is immense potential in this device just need more developers to iron out the kinks.
[Android General] chronic8000:
It is quad band for 3G and dual band for the second sim. Though you can swap between the 2 which sim you want to have 3G from anyway. I got it from Aliexpress in China, but it just will not hold a 3g signal seemingly from any network. It works sometimes but most of the time it says either "No Service" or "Emergency Calls Only" with a red x through the signal bars or it says Edge or GPRS. I thought at first it was the network but I have tried 3 different ones and they are all the same. I swear it is a baseband problem rather than a hardware problem.
[Android General] ohagas:
Thanks. Is this the app? (some reviewers say its' rubbish!):

Ignore the ticks it is the basebands in white the phone supports and the ones in grey it doesn't.

I unticked some of the basebands to see if I could get the signal more constant. Didn't make a difference.

JiaYu G4 is also another option using the same MT6589 quadcore + SGX 544 GPU, along with ThL W8, Ou Sheng (iocean) X7, Huawei Ascend P2...etc.

As for rooting, I believe I read somewhere (forgot link exactly, you can probably Google it), most of the Chinese phones come with an app that roots & installs SU for you (it's a security hole, but a small one). It's an extra step that's required and not activated for those who don't want it. Same goes for enabling Google Play & non-Asia GPS servers.

confusing is ram, 1 or 2 gb?

at text wrote 1 gb, on some picture also 1, but on antutu score 2 :confused:

and how much mah has battery, 3600 or 3000 mah (3000 wrote on some similar phones)?

and this phone is not rooted, how done it?
[Android General] Whyzor:
RAM is 1 GB, the 20xx in Antutu is just the score in memory tests. Battery is probably 3600mAh considering how big the thing is, it can hold a big battery, but I'd be skeptical, so call it 3000mAh. Rooting will have to wait for people who actually get it to know. Or ask HDC tech support.

Fastcard is one of those places nobody recommends because they always lie about something, so I wouldn't take their videos as proof.

Sadly the only way to know about the 6589 power is to wait for users to test it. I was shocked at how bad the 6577 ran games like nova3, I thought for sure it was better.

I would really not get the 1080 guys, it takes a lot of power to move so many pixels and there is a reason why the Nexus 4 has a 720 screen even with a much better chip.

[Android General] NixZero:
true that you cant take most chinese dealer at their face value but you can compare an item with other similar items.

we knew that 6577's sgx531 was really, extremely bad from everything else that mounts it, we know at least another device with 1920x1200 display that mounts the same sgx544mp1 gpu as 6589: the 8.9" kindle fire hd and it plays games decently even if it has a slower cpu than 6589.

so, yeah, you wont have snapdragon 800 performances but nothing as bad as 6577 ones, even at 1080p resoultion.
