Moving from China to Indian Firmware. - LeEco Le Max 2 Questions & Answers

Hi guys,
I just bought a Chinese version of the X820 and I was wondering how do I move from China to Indian firmware? Do I do it via the updater and download the Indian firmware and renaming it to update.zip? (Not rooted)
and another question, which is better, Chinese or Indian version?
Thanks.

Yes, you can. I have flashed rom 16S X821 India for my mobile. Everything is ok.

Thanks. Which is better for you?

Hi, wanted to tell you that I moved from the chinese to the indian to the us version, didn't use the indian one, but between the us and chinese, the us is better as it doesnt have as much bloatware (for the rest is pretty much the same)

I had problems setting up the APN for my data on the Indian version tho. The China one was fine. Is saving APN working fine on the US version?

I didn't have to do anything after flashing the US one, so I would say that it just works.

Do all LTE bands sill work, whichever firmware you use?

Don't know about all of them, I'm currently in Asia, and this this had originally the Chinese version, flashed the us and still get 4g in Malaysia, Thailand and Singapore.
I'm inclined to think that they do work no matter the ROM.
Btw, I was trying to go from Chinese 14s to US 16s and it got stucked in a boot loop, so I flashed again the Chinese, then went to the Indian one, I think 15s, and then the US one, it worked without an issue that way.

Now i'm using CN 16S. I have a problem with 4G+/LTE-A in Malaysia.
When it switch to 4G+ coverage, all phone signal include data and call will lost (Can't use at all)
No toggle switch to turn off 4G+ only, but able set preference to 3G to run without signal drop (Only HSPDA)
Now my containment solution of this is :-
In Malaysia, telco using CA for Band 3 and 7 for 4G+. The coverage for Band 3 is higher than band 7. So i disable the Band 7 to stop the phone switch to 4G+, I still able to enjoy the 4G of Band 3, rather than only set to 3G (HSPDA)
Anyone with better solution, please let me know. Thanks

Hey, I'm from Malaysia too. Had the same issue. You got to make a new APN. Eventho it looks like an APN has already been set, it still won't work. I find my LTE to be working again after I set a new APN.

What if i choosed the wrong ROM country?

I am having a problem with 3G network for along time even though we have 3G coverage in my place
i installed lolipop 5.0.1 and it worked perfectly but the 3g problem still
im in north africa but my phone manufactured in brazil ,under the battery it's written ANATEL and a number of 10 digits following it Do you think this phone works only in brazil and only under Alcatel. network ?
now an idea comes into my mind is to install a brazil region ROM with a brazilian carrier , but some told me ROMs are all the same and it won't resolve your problem
Do you think this phone works only in brazil and only under Alcatel. network ?
Dear experts please advice me in my case .....Thank you in advance
Each phone is set to use different bands. So unless the band's match up you will have issues.
but i do not have that carrier in my country here
It's not the carrier. It's the band's that are programmed into the device itself. This is something you have to be very careful about when getting devices from other carriers and countries as they don't all use the same bands.
I would look your phone up and see what bands it supports and then check what bands tour carrier uses. It's most likely they don't use the same ones so you will never see 3g.
so how do i check the programmed band on my phone?
By checking the device under the carrier that it was made for.

will rn4x China version work on LTE under Global Rom?

First of all, thank you for paying attention to my question and sorry if my English is not good.
Hi, im from Chile and I bought a RN4x Global with Qualcomm, but the network works terribly slow. I just discovered that the phone originally had the China Rom (Box is half Chinese half English) but it was flashed to Global Rom by the man who sold it to me.
May that be the reason why it is so slow? (I mean, may the network be so slow because it doesnt work under the LTE band of my carrier?)
In short: If someone flashes Global Rom on a Chinese version phone, should it take the same bands as a originally Global version phone?
Thank you very much for your answers!
Hardware wise, the Chinese and Global versions of mido (your device) are identical. They should both support the same modem bands no matter the ROM version. If the global firmware is installed then that is the best you can do. But you could always flash the global version yourself just to be sure, though I can't help with that - there are already heaps of guides out there for that.
Not supporting certain LTE bands that you carrier needs won't make it slow - it will either work or it won't at all. Problem must be elsewhere.

1. Yes
2. No. Jio VoLTE will NOT work.
3. Bands may be supported, but if there is 4G+ (LTE-A) in India, that may not work. And if you use a Jio SIM, only data will work, no voice calls due to lack of VoLTE.
4. No it won't.
5. Aside from the fact that VoLTE / LTE-A will not work on any network. Not really.
Regarding the band compatibility;
The S9+ USA model supports the following LTE bands (source: https://www.gsmarena.com/samsung_galaxy_s9+-8967.php)
LTE band 1(2100), 2(1900), 3(1800), 4(1700/2100), 5(850), 7(2600), 8(900), 12(700), 13(700), 14(700), 17(700), 18(800), 19(800), 20(800), 25(1900), 26(850), 28(700), 29(700), 30(2300), 38(2600), 39(1900), 40(2300), 41(2500), 46, 66(1700/2100), 71(600) - USA
India LTE bands (source: https://m.gsmarena.com/network-bands.php3?sCountry=India)
LTE 850 (5), LTE 1800 (3), LTE 2100 (1), LTE 2300 (40), LTE 2500 (41)
So you should be fine regarding LTE compatibility (not sure about VoLTE and LTE-A).
Regarding warranty only the local Samsung customer service will be able to answer this 100% accurate (most likely no warranty).

As far as i know
1. No. You need to insert a country specific sim to activate/unlock the device.
2. No.
3. Yes. But in the first place you need to unlock the device which is not possible.
4. No.
5. You cannot root the device because bootloader is locked in snapdragon version and No carrier aggregation(LTE-A) support because the ca combinations are country/CSC specific.
Hi,
I have US bought tmobile unlocked s9+ device..JIO VOLTE doesnt work .. is it not fixable at all ?
Or is there a way out ?
Thanks
Bharat
M too facing same issue.
I researched a lot in last 2weeks on same but of no luck, found our that regarding volte the issue arising in many countries,
Small positive info got day before yesterday in s8forums Tgey said it was due to CSC in the firmware . And now a days all firmwares are multi CSC loaded, but since we used the phone in usa CSC from there was loaded, so I order load indian CNC we have to do the below.
if they just activated the phone after hard reset using indian sim they were able to use usa version with jio.. But I tried that too in vain no luck for us.
You may try above but.. you may lose data.. advise smart switch feature to sd card... if willing to do hard reset.
Please update if any luck

I have not played with these before ..like installing firmware and all..mine is SM G965U model .. not sure the method mentioned would work ! 965F us international model ? And tweaks to this model only work not US models ?
I checked with Samsung too.. they said its country specific .. i dont know whether to try this method or leave as it is !!
Thanks
Even I got stuck over us CSC, and all samsung pay rewards which were only for us citizens..
Mine is G965U1, VOLTE doesnt work in india.
Since snapdragon not yet unlocked I had no options for VOLTE.. even If I do I may have to let go the Spay...
My advise don't Buy.. during deals we almost get similar rate e commerce sites in india...

Hey,
I am facing a similar issue. I got a unlocked USA S9 SM-G960U1.
I am using it in India but VOLTE does not work.
I am looking for a workaround. Any help will be appreciated
Thanks in advance
I have a S9+ snapdragon from T-mobile. Recently visited India. Jio volte does not work which was expected. But Airtel had bad reception and the internet would not work even intermittently when the 4g symbol was in display. However, in the same location, side by side, another airtel number on moto g worked flawlessly.
Even though the S9+ specifications shows all the network bands supported by Airtel, i did not expect to face the above problem. I am planning to sell the phone in the USA and buy a oneplus from India.
[SOLVED] use JIO SIM card on S9+ US Version in India
I purchased an S9+ ATT in December 2018, tried to use JIO SIM in India but no luck , then I wanted to get rid of ATT logo, which comes up every time I reboot my device. Did some research then and came across this forum https://forum.xda-developers.com/galaxy-s9/how-to/how-to-flash-u1-firmware-to-device-t3765200.
Was able successfully flash my device to US Unlocked version from ATT version 4 months ago , now I can see VoLTE toggle. Again tried to use JIO SIM , didn't work . Since then my device gets regular OTA updates :angel:.
AIRTEL network in my area sucks, Now 09/2019 again I tired to use JIO SIM and it works flawlessly.
HELLO I HAVE GALAXY S9+ U.S. VERSION. my jio sim is not allowing voice calls, and messages in this . Can anyone transform the trouble shoot method please
Like wise it is not working apple ( us version) 6 too

download the firmware for your carrier from www.sammobile.com/firmwares and flash it via Odin. If its the same android version, br sure to use the HOME_CSC file when flashing vs the normal CSC file to avoid an unnecessary factory reset. Flashing the HOME_CSC vs the CSC will allow you to keep all your stuff on your phone, CSC will factory reset it.

voLTE wont work unless you flash the CSC for your carrier on the device. voLTE is a carrier specific thing and requires the carrier specifc software to be installed which happens when the correct CSC file is on the device and the corresponding sim is entered

Wifi Calling not activated - ROM issue?

Hi
received my Mate 20 Pro 256GB Dual Sim from Trading Shenzen.
So far great device, but missing Wifi calling.
There is no option to activate in settings.
My phone details:
Modell: LYA-AL10
Build Nummer: 9.0.0.161(C00E155R1P20) GPU Turbo
So maybe i had to switch to another firmware.
Wondering in hiSuite: Got information there that i have the newest Developer Version?
So can some assist / help to get wifi calling?
Or is it possible to flash LYA-L29 to this device?
thanks
I've never had WiFi Calling on any Huawei phones running EMUI or Xiaomi phones running MIUI but I am in the United States. MIUI doesn't have any option for WiFi Calling but maybe EMUI does depending on region.
You have the Chinese hardware version so I don't think you will be able to flash any international firmware on it but your best bet to find out would be to contact FunkyHuawei.
In case you haven't heard of them FunkyHuawei is a paid service many Huawei owners use to flash firmware updates, rebrand their phones to different regions, obtain bootloader unlock codes, etc.
I'm not personally endorsing the service (although I have used it) but the person who runs FunkyHuawei would probably be in the best position to answer your question since he reverse engineers the software on Huawei phones and owns Chinese and international variants of the Mate 20 Pro.
Can’t go from China to Non-China
Hi I have the same problems (want to move from Chinese LYA-AL10 to a non-Chinese version such as LYA-L29 for instance).
I ask FunkyHuawei and they replied to me «*cannot go from China to Non-China*»
If someone still manage to do it, please let us know !
Cheers
I have the lya variant I picked up in Malaysia on vacation. WiFi calling does not work with my T-Mobile (US) SIM card. However it does work when I had a Malaysian Sim card in it. The option would show up in the sim settings. From what I read WiFi calling does not work outside of Asia.

It does work outside APAC...I'm in Canada and while my provider (Videotron) has NOT enabled VoLTE and VoWIFI for this phone, I borrowed a Rogers (other CDN provider) SIM and VoLTE and VoWIFI were available. The provider has to enable these features for a particular phone.

LG V60 TM Unlocked Greece 4G/5G Bands

Hello i have imported an LG V60 TM to greece. It is my second time that i import a lg v60 to greece. The first time was 2020, and back at the time that lg v60 TM was having 5G in my county (i dont know how..) now the second time i bought a TM model, i have not all 4g bands and i am missing 5G. The TM is as far as i know app unlocked. What i can do to enable 4g+ or lte or 5g to my lg?
It is now updated to A13.
Thank you all.
Do you by any chance have the model, rom, or any other data from youur previous phone that had 5G?
I'm also in Greece on Cosmote and haven't found a way yet to get 5G on my v60 (TM originaly, but converted to EA). I have tried 6+ roms (v10,11,12) without success. The TM rom might show 5G on the top right but NetMonster says its actually 4G. If you have some luck plese update the thread. Thank you.
No I don't remember the model the rom was definitely TM original. But the main difference from the one I have now. It's that mins now has something that tries to activates network but it failes. And then I did not had that.
Also can you share info about your lg60? Mine says it has LTE but I only can reach 30mbps in Athens . I can see band 3,7,20 but I don't think volTE is working.
I get similar speeds as you in 4G, maybe double in good cell towers. VoLTE, VoWifi never worked after trying many posts on this forum, with rooted device. I decided to stay in stock and check for solutions later. I think I should start looking for JigsawMobile moded modem files and if this doesn't work reinstall my original TM rom backup to get the Android 13 OTA. If anything comes up I'll post updates.
What information would you like from my V60?
