[Q] Lumia 900 Country Variant ROM Flash - Nokia Lumia 900

Hello,
First I would like to note that because I am a new user with less than 10 posts, I am unable to post in the development sub section and I was redirected to post in the general forum.
I would like to know if I was to flash my Nokia Lumia 900 to for example country variant Vietnam whether I can have all of my localisation settings defaulted to Australia and have no hint of another countries settings on the phone at all?

AT&T Lumia 900 input language?

I live in Taiwan, and very interested in AT&T Lumia 900
Anyone knows is there Traditional Chinese input in AT&T Lumia 900? and what's the selection of UI language?
I hope it has Traditional Chinese input, if it has Chinese UI is much better
Please figure it out if you have it already!
Have you looked at the bands the USA version has? LTE isn't example compatible to the LTE bands here in Europe, neither is 3G.
For your original question, no idea. My Lumia 800 does seem to have Chinese as available language.... i think...
My AT&T-branded Titan has Chinese input available. There are a few different kinds (bopomofo, etc).
It also supports international UMTS bands (2100) so you will get 3G unless you need 900MHz or AWS support (which in Taiwan, you almost certainly do NOT need). I used mine on 2100MHz 3G networks in Singapore and Hong Kong.
No reason to think the Nokia will be any different. However you might have trouble getting it unlocked.
Thanks for your reply
Unlock code can be bought in ebay, it will be no problem
Because AT&T Lumia 900 only has English and Spanish UI, is it possible to add Traditional Chinese UI for Lumia 900?
In terms of input, I think all have tradchinese handwritten input, ui language, I think only samsung (bleh!) has, so far, put all wp7 supported languages on their usa bound devices. I am simply unsure if htc and nokia have likewise done so.

[Q] Rogers Lumia 900 for use with Fido

I did hit the search button with no definitive answers.
Does the Lumia 900, bought from a Rogers reseller, then unlocked, then used with a Fido Micro-Sim (already working in a Lumia 800) will have Tethering active (or or can be activated) without additional fees (other than paying for a real data plan, which I already have) ?
Fido does not have any LTE activated, am I right? Don't really care, just to clarify.
Can the Rogers-specific apps be uninstalled?
Is the Nokia Network Setup app available and installable (was installable before on my 800, but now says unavailable for my device in the marketplace, but still works on the phone)?
Phone will have Rogers logo on startup and Rogers colors (Red) instead of the Nokia blue? And since there's no generic Rom's (yet), it is not possible (yet) for North America to unbrand it?
On the same subject, would it be possible to flash the rom with a generic one from the RM-823 list, without 'deactivating' the North American bands (and not 'activating' the european bands)?
Are there manual Cab updates for the 900? I have unbranded phones since 2004 and don't want to be dependent on the original carrier for those important updates that may not be considered important for Rogers.
A few questions, but I don't want to buy a $525+ tax device that will not be as likable as my factory unlocked/unbranded Lumia 800.

Not sure I can answer everything but Fido does not have LTE. In fact I don't even think they have 4G. I'm not sure if tethering works or not. Yes the Rogers apps can be removed easily. Yes Rogers logo will be on bootup. Not sure if you can flash unbranded rom yet since we've seen no luck with AT&T model either. Nokia apps will be available for it as per whatever is in the Nokia section of the Marketplace. No their arent any cab updates. There was the last update which was available for all phones to force the missing keyboard update and could be installed by cab files but that's all I've seen since.
Some of my questions were answered in my research.
Thethering is a gray zone. No definitive answers.
Fido = 4G max. No LTE (yet). It may be announced as a back to school promotion a Fido rep told me. But would require a new SIM card which support LTE?
Uninstall Rogers crap = yes.
Nokia Network Setup app, still not available (as per Marketplace) on my 800, which seems to a North-American 'problem' (there's a topic on Nokia suppot on this). This needs to be confirmed or infirmed by someone who can install or update with a North-American Sim.
Branding may be removable if flashed with a generic rom from Europe, if the radio part is not affected by a flash (as with the 800).
Cabs have been seen, so manual updates = yes.
My experiences on Fido with Lumia 900
Hi,
I would love to hear other peoples experiences with the Lumia on Fido. I am going to mention mine below and would love to hear if any others have experienced the same.
First I would like to say I really enjoy the Lumia 900 although I do have some qwirks that I will mention.
As mentioned previously you can remove the Rogers apps since they don't work. The rogers branding does show up on start up which doesn't bother me that much.
What does bother me is that the phone seems to be slower loading data then Samsung Focus I previously used when on the cellular data. When on Wifi the phone is blazing fast.
I did reset the phone with the Fido sim in it as I initially didn't have it in on setup but it still seems slow when browsing in the browser or even in the market places.
On that note my experience is that this phone switches bands quite frequently in places none of my phones have ever done so. For example the Lumia in Toronto near the airport will drop to Edge and I don't remember ever seeing my focus drop to edge near the airport. The lumia in fact will drop to G here in Nova Scotia where I am temporarily working where I never had an issue on my Focus.
This can cause using the data functions on the phone to be frustrating at times. I would love to hear if anyone else has experienced this.
Thank you and please feel free to ask specific questions about using with Fido.
Thank you.

[Q] Lenovo Z90-7 (VIBE SHOT) 4G UK HELP PLEASE?

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be connectiong to 2.4ghz network instead of 5ghz. Also I cannot get mobile data working.
What ROM/kernel did you flash? Many ROMs run 5.1.x

Hi I used this rom Z90a40_USR_S118_1505272046_Q2020131.4_ROW_qpst
which was mentioned here on the forum as the best for Android 5.1
Hey man, I've done some research and it seems your ROM/phone should support LGT(4G). I would highly suggest completely wiping your phone, reflash ROM/ Gasps/ kernel (if you have one) and see if the issue persists

The seller says I can send the item back for a full refund but unsure if he will give me a refund as I've changed the ROM to 5.1 The worst thing would be sending the device back to China
Okay, have you tried manually setting your APN? Fallow the steps below and findnthe APN settings online for your carrier, let me know what happens.
Many users have told me their 3G/4G LTE data network connection is broke after installing a custom ROM. *Well, in most of these cases, it can easily be fixed by manually setting the APN (Access Point Name). *This applies to any GSM networks such as*AT&T or T-Mobile. *For CDMA networks like Sprint or Verizon, they also use APNs but you don’t have to set them and should work out of the box.
Every carrier uses its own APN Settings to get its 3G/4G LTE network working on an Android smartphone or tablet device. *Now, these APN settings are usually “downloaded” automatically to your*phone*when you insert a SIM card. *BUT, there are times where the APN are not selected automatically OR when the APN settings are not downloaded.
In those instances, your 3G/4G LTE data will not work but that can easily be fixed.
Step 1. First, browse your Settings menu and find the “Access Point Names” menu. *This is usually under “Mobile Network Settings” or “More*mobile Networks or “Mobile Networks” under Settings menu depending on the Android device used.
Step 2. Once you are in the APN Settings menu, first thing you should check it that the APN is on the correct one. *If the correct APN is not checked (sometimes this happens), simply check ON the correct APN for your carrier. *That will make your 3G/4G LTE data working right away
tep 3. There are also times where the wrong APN is listed or there’s simply no APNs listed. *In these rare cases, you can simply add a new APN, hit the “+” button.
Step 4. For APN setting, the “Name” can be anything. *“APN” setting is the most important, usually you only have to fill this out for your phone to work.
For T-Mobile, you can set the “APN” to “fast.t-mobile.com”. *AT&T, you can set “APN” to “phone” or “pta”.
Now setting “APN” will get your data working but you still need to input additional settings to get your MMS working.
ep 5. You can usually Google APN settings for your carrier. *Whether you are in Thailand or in the U.S., simply Google for your APN settings like:
Google “t-mobile APN 4G LTE” for T-Mobile 4G LTE APN settings in the U.S.
Google “True Move APN 3g” for True Move 4G APN settings in Thailand.
Eventually, you should be able to find the full APN settings for your carrier whether you live in Hawaii or on North Pole.
Once you have the correct APN settings, simply input them into your APN settings on the phone
Step 7. Next, make sure to select the new APN Setting you have saved. *Within 5-30 seconds, your phone should start picking up 3G or 4G LTE signals and your data should be working again on the phone.

Hi guys,
I have just bought this phone and flashed it with the latest firmware Android 5.1 as per the post on this forum. I am now very worried because my phone only seems to be working on 3G. When I go into settings and network it only gives me the options to pick a 3G network. I did a lot of research before buying this phone and was assured it would work on 4G within the UK my old phone the Sony Xperia ZR worked on 4G fine. I do have the latest nano sim.
Here are the details of the Lenovo Z90-7 As per GSM Arena
Technology
GSM / HSPA / LTE
2G bands GSM 850 / 900 / 1800 / 1900 - SIM 1 & SIM 2
3G bands HSDPA 850 / 900 / 1900 / 2100
4G bands LTE 800 / 1800 / 2100 / 2600 - Lenovo Z90-7
And from my network operator's webpage I get the following info
4G from Tesco Mobile (o2) uses the following network frequencies:
800 MHz (0.8 GHz)
Am I having this problem as I flashed it with new firmware?

I believe the phone doesn`t have the LTE 800 frequency.
Search other websites than gsm arena.
That`s why you don`t get 4G.
Hi Friends,
Thanks for the quick replies I really appreciate the help. In regards to the APN settings I've checked these and these seem to be correct.
So it *Should* work EE
Interesting, I was hoping the APN settings were the cause. I'm sorry you couldn't fix your issue. I'm sure you will have better luck with your next device.

Valter84 you are correct I spoke to the seller and he advised that there is a mistake on the listing the phone does not support the LTE 800Mhz frequency.
So it *Should* work in the UK on the network EE which uses Band 3 FDD LTE (1800mhz). I've tried an EE sim and it still does not work at all on 4G.

Hi, I have the same trouble as you , anyway I have not flashed my Z90-7 yet. My chinesse seller from Aliexpress claims , that this phone supports all usual LTE frequencies including 800 Mhz.
But I can use here in Czech republic at T mobile provider only 1800 Mhz which covers only Prague and Mlada Boleslav . Rest of our country covers LTE on 800 Mhz only.

This seems to be a worldwide problem outside China. It is nothing to do with APN settings, etc.
A company is selling this phone on Amazon USA and they have specifically mentioned 4G does not work in the USA.
I am based in the UK and 4G doesn't work. I have flashed the phone and have now android 5.1 installed on it, but until official EU version of this phone is released we will be stuck with 3G

I can't connecting 5ghz too.
Just only can connecting 2.4ghz.
I can't find 5ghz network in WLAN list.
I succeeded installing the ROM. (use MiFlash tool)
ROM Version: Z90-a40_S118_1505272008_ROW
So, my phone's android version is 5.1
Z90-7 device can't support 5ghz WIFI network? or ROM's problem?
I want to know about this problem's solutions. (I want to use 5ghz wifi network!)
If anybody answer for me, I'll be very grateful.
Thanks for reading.

Dear people, wake up, many Chinese markets are deceiving customers by providing them misleading information. LTE bands is one clear example. Chinese LTE bands are diferent and they just flash the device's ROM for multi-language and add Google Play to make it "international version" but it is not. DON'T BUY IT!
I double checked with this company minideal.net which i cannot recommend. The company confirmed full FDD LTE (4G) functionality on following frequency bands: 800/1800/2100/2600MHz. But my smartphone IS NOT WORKING on 800MHz in The Czech Republic because it is only 1800/2100/2600MHz in fact. Within the PayPal Dispute and Claim they completely turned around their statements concerning LTE bands.
Complete tests were made with my network operator provider to rull out other problems. You can easily check that in these comments and in some fair e-shops where they don't twist the truth.

This is correct, the phone doesn't work on 800MHz. However it should because Qualcom 615 supports 800MHz. the reason it doesn't work is because the modem is probably locked within the ROM. I am hoping once this phone is release european version then it should work at 800MHz.

Hi, i already have had the European version of Lenovo Vibe Shot (chinese name Lenovo Z90-7) in my hands. I purchased it recently to compare the Czech and the Chinese model concurrently. All worked perfectly well with the Czech model. The device connected to 800MHz LTE band (band 20) INSTANTLY after the Android system start. No setting necessary at all. It connected to 800MHz T-mobile band in the Czech Republic. While with the Chinese only 3G or less! Another LTE band (2100MHz perhaps) worked well - Vodafone Czech Republic. So LTE hardware is ok but 800MHz missing...
The test is here: youtube.com/watch?v=Mv5RoN_BYSc
No doubt i was intentionally deceived by the seller namely minideal.net; and many others customers are being deceived the same way!

Well, i consulted this with some mobile phone services earlier and they did not recommend updating the ROM like that. Your device can end up dead after it. The ROM must be perfectly tuned to the particular HW specification of your device to avoid the fatal consequences. It is quite risky... i was thinking the same way. I am disputing the seller via PayPal asking for partial refund to be able to re-sell the phone to someone who can do without 800MHz.
Also you cannot freely update the android system without loosing the multi-language and Google Play... So shopping mobile phones in China? NOT A GOOD EXPERIENCE FOR ME!

Ok, i understand your point. I was thinking the same way. Some mobile phone services would refuse to update the ROM like that though, because it can kill the mobile completely. And who will take the responsibility? The Chinese dishonest dealers should! Let us tell them, we don't like their deception and lies! They are playing the "we don't know" game, but they surely know enough about the differences between Chinese and non-Chinese LTE bands.
But yes, there should be a way to change the ROM the same way the distributors of the real European version of this phone do it. Only where shall we get that ROM and ROM update done? Because, as i have already experienced, the local (Czech) Lenovo representation has no interest in helping owners of Lenovo products purchased in China. How predicable...

MetroPCS 4G LTE on Lumia 640 XL LTE?

Occasional lurker, first time poster. I found out about this site by way of the Windows Phone subreddit. They've helped me out quite a bit, but I seem to have encountered a problem that they aren't quite able to solve.
I recently bought a Lumia 640 XL LTE (Model #: RM-1063; running Windows 10 mobile) thinking that it could be used with my MetroPCS service. The phone apparently comes from AT&T, and it may or may not have the appropriate hardware capable of being compatible with MetroPCS's 4G LTE network (according to gishan dot net).
I tried calling MetroPCS to switch from my Lumia 640 LTE to the 640 XL LTE , but they said that it's incompatible with their network. They also gave me a list of compatible phones; none of those on the list were Lumias even though I had called them from a Lumia. Someone on the Windows Phone subreddit told me that "spoofing" the Lumia 640 XL LTE as another phone (a Lumia 950 XL?) using Interop Tools may resolve my issue. I figured I would come and ask about that here, but the XDA forum is enormous! I managed to find this subforum, but I don't even know where to begin to look for information on my specific problem. Conducting a search for resolutions to my problem didn't yield any adequate results either.
I would like to use the phone I bought (the Lumia 640 XL LTE) on MetroPCS's 4G LTE network. Is that possible? If so, how would I go about doing that?
I understand that there are certain sections of the forums for certain problems/projects/questions/etc. If this is the wrong place to ask this kind of thing, I apologize: please direct me to the appropriate forum.
