Does any body know if it is possible and if so how to enable the HSPA: 850/1900 band on a Global (GSM/CDMA) Version of the TP2.
It already has the HSPA: 2100 enabled... so maybe someone RF inclined could shed some light on this question.
Thanks
I dont believe it has the hardware to do it. It is not a software tweak.
That is why so many people waited for the ATT version to come out. There is an Australian version that works on one of the bands but not both.
Sorry to say that I think you are wrong about the Hardware reason...
Apparently the Pro2 has the chip installed, but it's locked down some how. That info has been floating around from an inside source at Telus. they say it actually has 850/1900/2100 UTMS bands but just got "locked" by Telus.
Also sites like Engaget has long posted some HTC FCC info proving that; http://www.engadget.com/2009/05/20/htc-passes-cdma-gsm-hybrid-touch-pro2-through-the-fcc/
Also The TP2 uses Qualcomm's MSM7600. The specs for that processor allow two major sets of radio interfaces, only one of which supports CDMA 800 and 1900. That major set has two variants that support HSPA: 2100+800 or 2100+1900+850.
So the question is; is there anyone with the proper knowledge that can tell what is onboard the TELUS TP2 and if it has infact the variant that supports the North American frequencies, how do we enable it?
Thanks for posting with FACTS and not Thoughts as this is the only way we will get a valid answer to this question.
Hmm this is definitely an interesting idea. I'd love to have the front facing camera of the Global Version, but I still need 850/1900 UMTS
850/1900 WCDMA on Global version
Gentlemen:
While the chipset has the various frequency capabilities, it is the tuning of the antannae that determines which frequencies are recieveable , ie, turned on, in the various versions. The AT&T version has a different tuning of the antannae than the global versions.
While theoretically possible, the anatanne is part of the main board and must be physically removed and replaced. I have not been able to find a universal antannae that could be resoldered to the board, if one was brave enough to give it a try.
there is software changes to the chipset controller required as well.
I think it is pretty impractical and likely impossible to do outside of have a new board installed with the properly tuned antannae to make it work. I have researched this for some time now, in an attempt to be able to use the EU versions here in NA. I travel internationally a lot, to Asia and EU, and need the 2100 band, so that has been my motivation.
There may be someone else out there who has different information, but this is what I have learned in digging through the available data for the past 3-4 years of various HTC devices and their variants.
Hope this helps,
MWS
I purchased the newly released UMI X2 Android phone. I am unable to use the TMobile 3G network. I am only able to use 2G/EDGE.
Voice and data quality are very bad, almost the phone is unusable. I spoke with T-Mobile and was informed that my modem does not support 1700 MHz and there are effort to re-farm TMobile network to support 3G on 1900Mhz but not set date yet. When I scan for available network I get three networks were available
T-Mobile 2G
AT&T 3G
AT&T 2G
Operating System: Android 4.2.1 OS
Processor: 1.2GHz MTK MT6589 quad-core processor
Connectivity Technology: GSM network & WCDMA - Standard SIM card
Network Band: GSM 850/900/1800/1900 MHz & WCDMA 850/2100MHz
Data Technology: GPRS, EDGE, HSPA
Baseband version
MOlY.WR8.W1248.MD.WG.MP.V2.P1
I would appreciate any help to get my phone to work on 3G.

Did you make any progress with this? I recently purchased UMI X2, for use with T-Mobile UK. But have the same problem of not being able to connect to 3G networks - it works okay on 2G/EDGE.
I know the phone supports 3G on 2100MHz, and there's been some debate whether it supports 850/900MHz as well, but I've not found a definitive answer to that.
There's an operator in the UK (Hutchinson 3G UK Ltd) that only have a license for 2100MHz. So I was expecting the phone to work fine on their network- but no go... phone won't register on network at all - even though it shows in the available networks list.
I'm now searching to see if anyone else has been having problems - as it's beginning to look like faulty phone hardware - rather than trying to use unsupported frequencies...
acid meaand
I am still in the same situation, I am unable to use the 3G network for T-Mobile.
I am looking into getting 4G Wireless Hotspot modem $50 from the same carrier, use my SIM card on the modem, and use my UMI X2 as pure IP phone. There are many issues, but it looks promising.
Please keep me updated with any progress you make.
Regards;
I have the same problem...
I have this same problem with a operator here in Brazil. Every 3G operator in Brazil, using 2.1GHz band, works fine except one: VIVO.
I can see the network when I click on "manual search", but the phone can't connect. My baseband is:
moly.wr8.w1248.md.wg.mp.v7.p1 2013/04/10 00:39
How can change this baseband to another? I tried to update firmware but unfortunately the newest firmware has the same baseband version.
firmware update will not solve the problem
Firmware update will not solve the problem. Until the manufacture identifies the problem and provides a solution, the problem is outstanding.
Beside the hardware has to be compatible and can support more frequencies which no one can confirm for the UMI or any other chines unlocked phones.
But, this is just my humble opinion.
I Found a solution (at least for me)
I think I found a solution for my problem. I flashed this very new (2013/07/17) rom, with a new baseband MOLY.WR8.W1248.MD.WG.MP.V7.F2.P1, 2013/07/10 23:14 that corrects 3G dropouts and disconnects. Now my 3g works find, with H and sometimes H+. Fast and reliable like it should be. The link for this new ROM is:
http://www.needrom.com/mobile/umi-x2-based-official-for-europeus/
Thanks for the update.
I have two questions.
1- There are two files in the link you provided UMI-X2-basedon_Official_250613.zip and UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. Which do use?
2- You mentioned the updated corrected 3G dropouts and disconnects, but do you know if the update have these frequencies to get 3G?
3G (850, 900, 1700, 1900, 2100 MHz)
HSPA+ 42
P.S
GSM/EDGE/GPRS (850, 900, 1800, 1900 MHz) original specs

I used the file UPDATE_UMI-X2-THB-ROM-based_on_Official_170713.zip. It was based on the Official ROM from 07/17/2013, but I was unable to find the official stock version. This version has a very new bandbase that, supposedly, fixed the problem with 3G on some operators.
3G on Brazil is on 2100 MHz, sometimes on 850MHz but in my case the problem was on 2.1GHz band. Three WCDMA operators in Brazil, all in the same 2.1GHz frequency, work fine, but VIVO doesn't. Now, with the new rom, it works with no drop outs for over a day now.
no changes or additional frequencies
I successfully applied the update but no changes or additional frequencies
I have serious issues with HSDPA, t-mobile uk works but only on GPRS and it keeps dropping out. GiffGaff seems to work without dropping out. It has worked for a minute on HSDPA today but only once. Other than that t-mobile has been dropping out badly. GPRS works for a bit then it drops out. I have took an MTK modem log with MobileUncle Tools to see what it says but haven't looked at it yet. Trying to work out if it is a hardware issue or Baseband.
I get this from my X2 Radio Logcat:

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

So, my phone's android version is 5.1
Z90-7 device can't support 5ghz WIFI network? or ROM's problem?

If anybody answer for me, I'll be very grateful.

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...

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...

ok so frequencies are from 900 - 1800 for all speeds E up tp 4G and are using At&T Mobile

I take this to mean 900 and 1800 MHz (bands 8 and 3), rather than the way you have it typed "from 900 - 1800" which makes it sound like a range, which doesn't make any sense.
I also don't think this information is correct (as I've interpreted it), as far as I can tell, 1800 MHz (Band 3) is not used for 3G anywhere in the world: https://en.wikipedia.org/wiki/UMTS_frequency_bands#Deployments_by_region_.28UMTS-FDD.29
You need to be sure of exactly what band is used for each (2G, 3G, LTE), before we can proceed:
What band (or bands) used for 2G?
What band (or bands) used for 3G?
What band (or bands) used for LTE?
It pretty rare that the same exact band or bands are used for all 3 (2G, 3G and LTE) by one carrier, so the answer is expected to be different for each, and should be asked, and answered on an individual basis.
Reason we need to be so specific here, is that there is no radio for this phone that supports Bands 3 and 8 across 2G, 3G and LTE (and in fact, no radio that supports Band 3 for 3G).
Once you've properly determined what bands are needed, and identified what M8 version supports those bands, the way to proceed would be:
1) S-off by sunshine
Note: If sunshine temp root doesn't work, you may need to unlock bootloader and root, before you can s-off with sunshin
2) Possibly need to change phone's CID and/or MID
3) Flash the firmware or RUU which contains the desired radio baseband
Even then, its not guaranteed that LTE will work. I've see a good number of folks on these forums that properly flashed the radio baseband (or converted to another version by RUU) that supports the desired bands, but still didn't get LTE service. I don't know why this happens, and have never seen a solution. But its a distinct possibility.
But at a minimum, you should be able to get 3G working on your carrier. Which alone may make the above process worthwhile.

Hello and thank you very much for you time i will go again and ask for more direct info's about bands individual
i have found back up of a radio and i flash my phone and now i do get LTE singnal's but hardly get H and 3G when no 4G detected it goes to E ... well ....
now i got another problem maybe i shou ld post a new thread ... my gestures won't work suddenly ( omg !! ) i calibrate and uncheck and reboot and check them from setting's over and over nothing worked

You need to specify exactly what you flashed, and where you got it from, for this info be worthwhile in any way.
Also, still need to know what bands your carrier is using, in order to determine what radio to flash.
Why you are flashing radios, without knowing if its the right one (supports your carrier's bands)? This is really careless and reckless.
Is the phone s-off? That is normally the only way you can flash radios manually (aside from a signed OTA, RUU, firmware.zip). And flashing things with s-off is a great way to brick the phone, if you flash the wrong thing (and it doesn't sound like you know well enough to know right vs. wrong).
Hello i have n910P, but it isnt work with europe LTE bands, then i want to switch motherboard to N910F, is it possible, or there are some methods to unlock LTE bands on P?
You will need to sell and get a GSM capable model. Switching motherboards just invites problems. Unfortunately the CDMA radios cant tune to the Euro frequencies afaik..
Almost every GSM model will work..just look into your local LTE bands available and research which devices support said bands..most will be at least dual-band, some will be tri-band, and some will be quad-band. Hope this helps, cheers
