[Q] Changing from TD-SCDMA TO WCDMA

I bought China made BBK Vivo XPlay model X510t which is running on TD-SCDMA. My country is using wcdma and thus I have problem with 3G. I successfully rooted my phone and replaced the Vivo XPlay X510w ROM. With the new ROM, all phone features running well but the phone still running on TD-SCDMA.
May I know in what way, I can get it changed to WCDMA?
Your valued advice is very much appreciated.
Thx/ Jim

Yeah you'll have to return it to seller and ask for a WCDMA version. There's no way around that.

Nope. Snapdragon 600. Still it have TD-SCDMA modem and i don't think there's really a way around it. Only replace it with WCDMA model.

like xiaomi mi3, this phone come with 2 versions, one is wcdma, another one is td-scdma, td-scdma only works in china. both versions are equipped with snapdragon 600. unless there is a way to flash radio @ baseband like nexus, lg @ samsung phones, i cannot see any possiblities to change it.

Hello everybody,
This is my first message.
I have the same problem with a Jiayu F1. The mobile runs with MTK 6572 chip and it supports both base band, therefore, i am sure that is a software trouble.
I have installed the WCDMA ROM and I lose the IMEI and the radio identification file.
Is there any possibility to unlock of the last option (OEM-specific info/setings) of Phone Information showed by MobileUncleTools? I think that the solution is here hidden.
Thanks...

im late read this post...
i bought HUAWEI HONOR 3C... with TD-SCDMA mode...:crying:
and i think no hope to get HSDPA signal now ?

I have lenovo golden warrior s898tp it is also td-scdma and mtk chipset
That is mtk 6592 using mtk uncle but it doesot show option only show td-scdma bands
What can i do

I have a solution, but it demands our collective efforts. Both MTK and snapdragon 600, 410 MSM 8916 has capability to process the WCDMA frequencies, but the phone makers disabled the function. Radio flash of the chips will enable the 3G, 4G mode of WCDMA. So lets work and see if there would be a simple way to do that. If you got answers whatsapp me on +2348064782500

'Unkown' Carrier Name

Hello everyone!
I downloaded this beautiful MIUI V5 Rom from here (http://forum.xda-developers.com/xpe...lby-effect-xloud-bravia-t2466608/post50871980) But i've bumped into a problem, my Carrier name says 'Unkown' i still get signal but i don't want my carrier name to say 'Unkown' how can i fix this? i've tried to downgrade to ICS and then flash this rom again but it didn't work.... Any Help!?

That is normal "problem" in cm10 for some operator... Another bug/problem is that baseband is named as "error",but it's working great
In new version of cm10, was that unknown operator kindly fixed,after while,the official/standard operator get original name.:laugh:

So is there a fix or not?
Because on the MIUI from lozochum it would show up a operator name (T-Mobile UK Suppose to be orange but it doesn't matter) is there a way i can take the baseband or something out of lozochums and replace it into zolys' one? or How can i fix this?

I have a G6-L33 from Venezuela (Movistar)
I flashed the G6-L11 because L11 , L22 and L33 are "THE SAME". That is a LIE, I flashed a L11 ROM into my L33 and I lost the home button correct functionality and also 3G and 4G. Now the phone's network is only EDGE.
I will try to do the roll back..

[Q] H60-L02 dual sim update from EMUI 2.3 to 3.0

Hi everyone, I got a dual sim H60-L02 from China (rooted by the seller) and using it in Malaysia.
The shop dealer asked me not to update the phone as I will not be able to use Malaysia SIM card upon updating to the latest firmware.
Is it something to do with the baseband?
Is there anywhere I can find the baseband if I updated the phone and fail to connect to the cellular services?
Do advise / correct me should I have made wrong statement.
Thanks.

sorry but it sounds to me you've got either a clone device or spyware from your seller. try the app Z device test to check the hardware

I have L-02 type, unrooted, using it in Malaysia, 1st sim Maxis and the other one use indonesia's SIM. It's running properly for 3G. I unable try 4G coz my sim card not support for 4G.

thanks for the reply.
Just to update, as there is a small note not to update to EMUI 3.0 while in rooted mode, I had factory reset the phone and then only updated the phone to latest firmware. Since Gapps does not available in China, I installed the Gapps from huawei app centre (Google calendar and contact sync adapter are available in that app centre) and the phone works well up to now except whatsapp chat history problem.
Hope you all enjoy Honor 6 H60-L02, definitely a phone worth to buy.

I have H60L02 .. Bought in Chinese... I am in India
I want or remove chinese app ..
Even in Contacts i could see chinese.. kindly Help in rooting it to International version EMUI

Xperia XA (Us Warranty) no LTE service

Good day all, hope I'm on the right place/post here.
Wondering if someone can help, I've purchased a Xperia XA F3113 via Amazon from SA.
Phone works 99.9%, the other 0.01% is my issue.
To start with all the settings are set to LTE(Preferred)/WCDMA/GSM, my carrier Vodacom has sent and verified that my sim is LTE activated (Used the same sim on other phones with LTE present)
Here's everything I did to resolve the problem....
1- Phone came from USA with android 6 and no LTE signal just 3g (In a 4G environment)
2- Vodacom sent settings and confirmed. did not work
3- Spoke to Sony and they suggested I upgrade software
4- Upgraded software via Sony Companion to Nougat Android 7
5- Vodacom re-send the LTE settings still no luck.
6- If I search the mobile networks it only finds 3g-Vodacom, 2g-Vodacom, MTN, Cell C NO LTE on any network. Screen shot Attached....
7- Think I've reached Google's end of their information network (searched everything)
OK so now I'm thinking I want to flash/re-install ROM/Firmware with SA (South African) settings due to different Base band versions.
I came across a link but are not allowed to post it yet due to my 1ste post on you're site. But the ink only have the "(F3112_1302-4393_33.3.A.0.127-R1B_Customized_SA.ftf)" for model F3112 dual sim and apparently it wont work on the F3113 single sim....
Google this: 2017/06/xperia-xa-android-7-0-nougat-firmware
Can Anyone maybe help or have some suggestions except for returning the phone.....?
Thnx

Hi, I think that it will not solve your problem. Did not you asked yourself why Sony sell 3 differents single sim device (F3111, F3113 and F3115)?
Look here and "Networks":
http://www.xperiablog.net/specifications/2016-xperias/xperia-xa/
And if I look here Vodacom SA uses LTE B3 for 4G:
https://www.frequencycheck.com/carriers/vodacom-south-africa
To confirm your problem if you look here you will see that only F3111 and F3115 will have 4G on Vodacom SA:

You can try but it will probably brick your device or Flashtool will not let you flash it (never tested). Firmwares are not unified probably for a good reason. Maybe an other user can confirm if it works or not

I don't want to break your hopes but the problem is not your network provider so changing some lines in build.prop will not enable LTE Band 3 on your device. It's a modem feature (or maybe related to modem firmware if you are lucky) so it's on the hardware side of your phone. You can try but I know the result The better way is to know if modem chips are same on all XA Single Sim and, if yes, try to flash the modem firmware from a F3111 or F3115.

Cool, will investigate and try that. Thank a lot

Flashing ROMs from F3111 or F3115 to F3113 is not a good idea. Like @rrvuhpg said it can brick your device. My advice is to send it back and ask for different model (if they have it, because you have warranty). There is also a possibility to change just baseband, but I don't have expirience in extracting baseband. I remember that when I used Huawei G510 I flashed MIUI rom with Chinese baseband and then developer added one small .zip file to flash it for other regions and it worked (but I changed that ROM because it takes too much resources for a that phone). So try contacting some senior developer or google for it, but do this if you can't change your phone, because you will lose warranty if you root phone.

Thank you guys I will definitively try some of you're advice's, thanks again....... Will give feedback asap. have a good one..
