[Q] Zenfone 2 ZE551ML: will crossflashing to WW change radio bands too?

Hello all,
considering a ZE551ML (the 2Gb RAM model) for purchase from a chinese shop. My question is the following. This shop obviously does not sell the WW version. Would flashing the WW version as per http://forum.xda-developers.com/zenfone2/help/how-to-upgrade-cn-version-to-ww-t3101556 change the compatible LTE bands of the phone as well?
IOW, is the hardware of all these versions (WW, CN etc) the same and it's the firmware that actually selects which radio bands to work in?

Thx for this question.
I search a solution for the the problem. I can not find a solution. How can change the firmware (moDem) to receive of a CN hardware version of ZE551ML all WW LT frequencies?

I did not R&D the product hence i would not know if china zf2 have all the same parts with ww zf2.
lets say if they are different then the case would be no
CN run on TDD while the rest of the world mostly run on FDD. this is not like software can overwritten, its 50% hardware (filtering (selection of bands)) and 50% software (methodology).
UNLESS CN zf2 comes with FDD function then you CAN cross upgrade firmware it from CN to WW. you should google it if it is true. Or you could ask Asus if they are willing to leak this topic to you.

Well, from what we've said so far, we're mostly speculating here. Perhaps someone has something definitive to share on the subject...

LTE band 1(2100), 3(1800), 38(2600), 39(1900), 40(2300), 41(2500)

@corrsea: I am aware of these frequencies. The original question holds though: is the difference in bands between these phones on the hardware or only on software?

Someone who has ZE551ML bought in HK (ZE551ML - 6G013WW) knows exactly which LTE bands are supported?
Based in LTE band list provided by Asus, it should be WW (Global) and ,since I am in China and can use China Unicom 4G network, I can not find it matching with WW supported bands.
Thanks!!

I'm pretty sure that simply flashing WW software on a CN phone will have no effect on the band's it can use. I should be receiving mine soon (CN from aliexpress) and will flash the WW firmware at some point. I'm hopeful that bands 1 and 3 are FDD and 1 will be compatible with my Telco, but who knows. Only ASUS can awnser whether the hardware is capable of being enabled for other bands but I'm not holding my breath for that one.
A Taiwanese zf2 would probably have been best for me but I could not access one easily.
This wiki page is a good resource when making these type of decision.

@corrsea: thank you for your ONTOPIC response mate. Will be glad to hear from you how it has affected reception to LTE bands.

HTC 10 International Version with AT&T (M10H)

Will it work with the LTE bands?
The seller on eBay say's it fully works with AT&T and T-Mobile?

HTC 10h (International version) WILL NOT work on US LTE bands
If you go to this page: htc. com / uk / smartphones / htc-10
scroll to the bottom where the specs are and look under "Network" you will see the differences between the radio bands supported by the International/Asia and the America versions of the phone. The International version DOES NOT support all of the 4G LTE bands used by ATT in the US.
This page shows the LTE bands used in the US by major carriers. phonearena. com / news / Cheat-sheet-which-4G-LTE-bands-do-AT-T-Verizon-T-Mobile-and-Sprint-use-in-the-USA_id77933
LTE band 5 is on both models of the phone, and band 5 is used in some very limited areas of the US, (but not enough to make it worth having a regional only phone at this cost, and the newest LTE uses dual-bands so that technology wouldn't work for you either).
If you live in the US, you absolutely want the US model of this phone if you expect 4G LTE and newer technologies to work for you over a wide area.
Hope this helps someone... I got suckering into ordering an International version off Amazon and it would not work on AT&T 4G LTE in my area (band 2).
Better to order the US version directly from HTC.

Does the opposite work? I mean, does the US version work in Europe or not?
I'm asking because the color I want is only available in the US and I live in Europe.

You should check which LTE bands your European carrier is using. Just google it "What LTE band does [your carrier] use in [your country/city]."
The US version supports all LTE bands except 8 (Saudi Arabia) and 32 (no idea where that's used..). en. wikipedia. org / wiki / List_of_LTE_networks

Hello, I have the same problem...How you solved it?

If you load the US unlocked on the international phone, you will pickup some LTE bands. I seem to be able to pickup 4/12, but not 2 with Tmobile

Hi I'd like to know if the US unlocked version of the HTC 10 (that you can order by the official HTC USA site) works on the Italian networks: band 3(1800MHz), 7(2600MHz), 20(800MHz);
so if I buy this phone and I do it to ship from America I can use it in Italy with any networks problem or restriction.
I'm very interested to know this, thank you.

m10h will not support 2/4/12 unless you convert to US unlocked. I have m10h and am on US unlocked. I seem to pickup 4/12 in some parts of the country, but have yet to see band 2. I'm also skeptical that I get all of band 4, I'm thinking I only get certain frequencies of Band 4.

So which version should I buy to use on AT&T in California?

Add LTE Band 3 to OP3?

Hi guys, so after a bit of research I found that you can add/enable bands on the OP1 as shown here
http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031
and Here
http://forum.xda-developers.com/showpost.php?p=56577252&postcount=455
My question is can I add LTE band 3 to my OP3 A3000?
Mine currently supports:
North America model(A3000)
FDD-LTE: Bands 1/2/4/5/7/12/17/30
The other models support:
Europe / Asia model
FDD-LTE: Bands 1/3/5/7/8/20
TDD-LTE: Bands 38/40
China model
FDD-LTE : Bands 1/3/7
TDD-LTE: Bands 38/39/40/41
If anyone has done this or attempted to do this please let me know

Looking for the same information.

Also been searching for this. Found another thread which says hopefully in the next month or two it will be looked into.

Its possible to add bands in Qualcomm devices .. i added h+ band in my Xiaomi mi note 1year ago. (Snapdragon 801) ... Somewhere in xda exist a tutorial to add bands in xiaomi mi note pro. Try the steps in oneplus ... But make sure you nandroid backup and EFS backup.

This is what I'd assume as well, but it looks like some have been successful in the past with Oneplus devices. Especially since Oneplus' response to the band omissions seemed a bit vague IMO.

Any updates?
I have a A3000 US model (Does not support LTE band 3)
AND NOW
I have just got a A3000 HK model (For my dad) (support's LTE band 3)
and the "about phone" part is identical apart from the baseband version.
Is there any way to tell them apart. And does this mean I can somehow unlock LTE band 3 on my US version of the OP3?
If there was someway to backup the basband and restore it on on my US OP3 that would also be great!

Hopefully something will come up..

Can this work on all carriers? Whether in North America or over seeas?

I've got OP3T A3000, tried multiple files and instructions to unlock LTE band 3 on it, no luck so far. Downgraded to Nougat, Oreo, different zip files, qcn files, hex editing stuff, most of these process went error free with still no band 3.

Redmi Note 5 China LTE Bands?

Hello
I plan on buying a Redmi Note 5, but I usually find the Chinese version 20$ to 30$ cheaper than the global one. I've read that there's no difference between the two except the LTE bands. My carrier uses the B3 and B20 LTE bands, can you guys confirm if the chinese version has these bands? I searched on Gsmarena but I got confused as it's listing a lot of countries there such as Taiwan and Indonesia.
Thanks!

So it does have LTE B3 band? Does that mean my 4G will work?

Sure it will work as long as the antenna you're connected to supports that frequency. Basically, you will lose LTE signal in every areas your provider only has B20 antennas. Maybe that's only a few, then again that also may be the most common configuration. You'd need a map of the network to know exactly how bad it'll be. Unless you know for sure, pay the extra bucks and forget about it.

Global ROM in China?

Hi guys, I would like to buy the S20 Ultra version in China from Samsung Store, to get the Snapdragon, but will be the Chinese ROM on it. Do you know if is possible to request to Samsung to have the Global ROM version? Or to install it at the moment of the purchase? Otherwise how can I solve this problem? Will be easy to do it by myself? Since is a expensive smartphone I don't want make any mistake..
Thanks for your help!!

Likely not. Hong Kong should get the SnapDragon. The Global model should be Exynos. Can't interchange the ROMs for it. Needs to be confirmed, but likely The snap dragon will behave better RF and battery wise. Maybe not a huge difference as with some older chipsets, but something to keep in mind. While Hong Kong may not get the OTA updates as frequently, you get a dual sim SnapDragon model.
hope this helps.

The Ultra international version is likely SM-G988F/DS, where the SnapDragon Hong Kong/Taipei version could be SM-G9880/DS.

The chinese versions typically have wireless bands that aren't supported in the US so I wouldn't use that. However, the Korean Version *will* use the snapdragons this year, and should be completely unlocked. Those should be fully compatible. I bought a Korean Note 8 because that was the only one which came in 256gb and the rare blue color and I've had no issues. It was Exynos, though. I'm hoping a lot of people in the developer community will buy this unlocked snapdragon version but I may not be so lucky. I might be forced to purchase the european "global" version.

Perfect!! Thanks, I will buy it in South Korea. Unfortunately they did it in only 2 colours this time...

Not sure which spec sheet you have seen. The SM-G9880 from Hong Kong should cover all the North American bands. AWS may be missing, I see it on some lists and not on others. I would be surprised if the Korean N version is better than a global F or Hong Kong’s 9880 version. I expect the 9880 to be similar to the U version but in dual sim format.

Yeah, I could be mistaken. My hope is just that with the Korean version also using snapdragon this year, people will be more open to buying that version over the International F. Development should be much easier and last longer with a snapdragon.

I hear you. I wish the Exynos was better, we’ll see what this new SoC will do, but the biggest hurdle as I understand it, it’s licensing and regulatory. I’m sure SAMSUNG would prefer to make a single version for the globe and just apply CSCs for customizing. To me, carrier and market demands are crazy. Single va dual sim, price, customizations, band support and features. If you put dual sim for everyone, a region will ask for a cheaper single sim. There’s no way around it, it’s insane.

Here’s the official band list from the Samsung China e-store. The 5G bands listed are more limited than what the Techwalls site says for GM-9880 (doesn’t support the US 5G bands listed there). The 5G bands listed are the same as the China Note 10+ 5G version, so it might be right. I was hoping it supported all the same US model 5G bands, but not sure now. If anyone has an actual G9880, sharing the real bands via an app would be great.

I think one of these apps will give you information of which 5G bands you are connected to. I thought there was an app where u could select different bands and force it, but maybe not or it has to be done manually. It looks like you are on T-mobile, so maybe you could try different areas/towers and different bands to test. On the Play store, there are also a few other 5G apps with maps of the different towers that can help you get close to test the high or low 5G bands. Thanks for your contribution. I’m really curious if both the high bands and low bands for T-mobile are supported on the 9880.

Hold on,
can you check the following please :
Settings -> Connections -> Mobile network and tell me if you can choose 5G on your SIM. Thanks
As for the moment on my 9880, i don't have 5G because "apparently" HongKong and Taiwan don't have 5G yet, thus it will be coming in a future firmware update. I tried to flash via ODIN the HK firmware but i got the BRI (Taiwan) CSC back again...

per my device :
5G Bands Sub6 N41 (2500), N78 (3500), N79 (4500)
But so check this, I have my 9880 and my girls 9810, both rooted unlocked etc.
She's on ATT i'm on T-MO
Neither of us are getting carrier aggregation. a S8 on t-mo got 102mbps and i got 34mbps in the same spot.

I just did it regardless of it being supported.
I'm on TGY now and i have 5G and the caller id\ spam protection options, but still no carrier aggregation, one step closer,

Do you want the following information?
I live in Taiwan, the phone model is SM-G9800
Taiwan ’s current telecom operators have not yet provided 5G services
If you need to provide other information, I will try my best to assist you

same issue here... got TGY on my 9800, i live in Switzerland and should get 5g or even 5g+ but nothing... i guess it's a frequency issue.
Now my question is : can we change the frequencies of the 5g on the phone?

Would anyone know if the sm-g9880 snapdragon model the 256gb 5g would work in Australia ? I think we use band 78? I can't find any details anywhere.

How are you able to get that? What app is that ?
My model is the sm-g9880 Taiwan firmware.
I tried to download the hongkong firmware but it didn't change the CSC for some reason. I did a full reset.
I thought maybe it's the firmware that's not approved for 5g yet because apparently Taiwan hasn't activated 5g yet.

Its called Quick Shortcut maker.
My G9880 was originally csc BRI but I have changed the csc to TGY using Samkey as 5G hasn't been activated on the BRI model yet but was activated on the last update for TGY.
