Purchased Honor 10 COL-L29 8.1.0.130(C636) No LTE on ATT - Honor 10 Questions & Answers

Hey guys any help with this would be amazing. I grabbed this for really cheap the other day and thought it would be able to use ATT LTE since others have had success but no matter what it will only connect to H+ even when LTE finder finds the band I wanted. Really frusted as I thought I got the right model. There is only ONE international one right? Any help would be really appreciated. Thanks you guys. Hopefully I didn't mess up and get a wrong version or something though I can return it if I did.

I'm having the same issue, but on T-mobile! I don't know how to fix this.

What I can't understand or just not knowing is the amazon version I have does 1,3,5,8 and up but the listings on Ebay have them 1,2,3,4,5,6,7,12 etc...basically all bands which I can't seem to figure out. Is there a difference? I have the UK model which is the Worldwide model not the chinese one but are there OTHER regional differences that unlock more bands? Is there a way to manually force this if so? I figured return to amazon and then get the ebay version but that is stupid if they are incorrect and they really dont' cover 2,4,5,12 for ATT that is needed.

I searched around today and found this. Scroll down to the connectivity part and you see that the phone supports 1 of 5 ATT LTE bands, and 0 of 5 T-Mobile LTE bands. However, I'm not sure if this information is accurate since my phone detects a neighboring band 4 LTE cell tower (which my old phone instantly connected to), but does not connect to it. Also, why is the rest of the forum quiet about this issue? Is it really just me and you that are experiencing it (or that live in the US)? I also am very confused why Huawei removed the USSD code menu option wherein you could force it to LTE. I've heard that changing something in the build.prop can force it, but you need to be rooted for that, and I've gotten bored of rooting phones lol (and the risks involved).
Luckily, for me, this isn't that big of a problem as data still works (albeit slowly), and in the beginning of September I'll be in France for at least a year. So, I made sure that this phone's bands matched up with what the carriers are on in France, so hopefully I should be fine. Otherwise, it's a sleek, awesome phone.

Honor 10 isnt made for US and US bands, even if its the global version. The bands in US are different from those in EU or Asia.
As the guy above confirmed this, the it has just one LTE compatbile band at ATT.

the one on ebay global version from Singapore is not what u think. there's a misprint on its ad. these are the actual bandwidths it supports ;
col~L29
Primary SIM card:
4G LTE TDD: B38/B40/B41
4G LTE FDD: B1/B3/B5/B7/B8/B19/B20
3G WCDMA: B1/B2/B5/B8/B6/B19
2G GSM: B2/B3/B5/B8
Secondary SIM card:
4G LTE TDD: B38/B40/B41
4G LTE FDD: B1/B3/B5/B7/B8/B19/B20
3G WCDMA: B1/B2/B5/B8/B6/B19
2G GSM: B2/B3/B5/B8
I want to tweak the build. prop, too, but root is required but, unfortunately, Huawei pulled that recent maneuver everyone frustrated about.

Yeap its a bit dead end without unlocking the bootloader. I dont know if by building and compiling original firmware from released sources and make the changes there, if it would allow you to install it.

Yes I too can pick up band 4 on LTE finder on my phone but I cannot use it, if I could then I would have fine coverage. If I go 5 miles away the other half of the city has full ATT LTE 5 coverage so I was bummed LOL when I went up there and saw full bars LTE+ LOL. Yeah the ebay guys are just putting false info then. I have my bootloader code to unlock as I have done to my V10 but not sure how that would enable the other band 4 I need. I don't have quite that much experience.

---

I don't know if there is something comparable to this available to be done (since Honor 10 has a Kirin and not a qualcomm), but I'm just going to leave this here for now.
https://forum.xda-developers.com/galaxy-s5/general/how-to-add-rf-lte-frequency-bands-to-t2886059
I don't know if Honor went the route of having a few more lte bands and just disabling them in software since my phone does detect band 4 lte, but can't connect to it, but what do I know.

---

I have the same issue on t-mobile network.
From all the research i did it looks like the US bands are software locked. P20 supports all LTE bands (including US) and it runs on the same chipset, Kirin 970. Also as few people said, they are able to see band 4 in LTE discovery (and other apps), I can see it as well, but can't connect.
As for the software to unlock lte bands, there is nothing like that for Kirin right now.
The only option for now is to find the right modem files, edit them and flash to the device. At least that's the only thing that comes to my mind.
I'm digging through source files, which were released by Huawei, whenever i have a chance, but i'm not even sure what I'm looking for.

really sucks because of all the phones I have (a lot LOL) this is by far my favorite one to use, the way the backing was slightly curved and everyting is just perfect except for that pesky LTE issue. I know they are software locked like you said but have no way of getting it unlocked. I hve picked up LTE 4 here as well but cannot use it at all. I can get full 4g LTE when I drive 5 five miles up the road LOL but only 3g+ here at my home which is the issue. Argggg.....i have about a week left before i have to return it or keep it so I'm on the fence. My honor v10 with 970 has all bands, and my P20 lite has all LTE bands too I just don't get it.

This is my favorite too. I guess Huawei really just wants to push the more pricier p20's in the U.S, even though they aren't really in the U.S. market to begin with anymore. With very similar specs to the P20 pro, the honor 10 would easily take away sales from the P20. Can't stop gearbest though, lol. Anyways, the extent of my modification to an android device was decompiling a rom (I think?), editing in specific MCC/MNC values for an AT&T MVNO in a certain file, recompiling it and flashing it to get 4gLTE back, since my phone thought it was roaming. I'm assuming the software-locked band information is a lot harder to find (or fix). I'm keeping my fingers crossed that HajmeR or others manage to find what we're looking for-maybe I'll even give it a go.

The question is whether LTE bands are only locked in software on your device or whether there really is a reason in hardware (missing antennas and such) that prevents you from using your preferred bands. People seem to disagree on this topic. Some claim that hardware reasons will prevent you from changing the set of allowed bands; however,
with respect to the Honor 6X, it seems that altering the oeminfo partition (https://forum.xda-developers.com/honor-6x/help/debrand-to-enable-lte-bands-indian-t3663359) can make a difference with respect to allowed LTE bands.
I have a Chinese Honor 10 (COL-AL10) which I rebranded to COL-L29 C432 by adjusting (not completely replacing) oeminfo, more precisely by carefully editing model number etc. Everything works well, but I noticed that the device does not connect to LTE band 20 towers that are in my neighborhood - even though I can connect to them when I put my sim card into a different phone. The Chinese COL-AL10 does not have band 20, so this lock or unavailability of band 20 seems to have survived the rebranding. A real COL-L29 C432 would be able to connect to band 20.
So, to investigate this further, one would have to study the oeminfo partition of a real COL-L29 C432 and investigate where information on the available LTE bands is stored - if this piece of information is hidden in the oeminfo partition. I can share the oeminfo of the COL-AL10 but have to make sure that my IMEI number cannot be extracted from it.

yeah i got my refund already from amazon and looking for a replacement, I don't like phones that are 72 mm or wider they are hard to hold, so my view 10 is tough at 75 mm..........the lg g7 is only 71 mm wide and 6.1 screen which is incredible but VERY pricey and it's LG, we know how they are on updates of ANY kind. I have the P20 lite too, which get's every single band in the USA on GSM, I don't get why the honor 10 was hampered so much because I'm not gonna buy the more expensive P20 i've used one and they are not nearly as nice feeling as the honor 10, the body is totally different not curved at all on back and feels like crap.
So the search is on, lenovo has an 845 with samsung super AMOLED on amazon for 450 with 6 gig RAM and 64 ROM and all the other bells and whistles edcept it's not glass on back which is actually like. I really really wanted the nokia 6.1 plus which is perfect in every way except once again 1,3,5, bands only LOL. So not go again. The Xiaomi A2 lite is interesting, metal back, 4000 ma battery which is insanely big, but then only 2.4 wifi and microusb LOL? 625 processor but only 200 bucks so really a good value and get's every band like the p20 lite.

I just happened to trade my Samsung Galaxy S7 to Honor 10 andit happens to be that what you're looking for. Can you help me out to help you how to get that information.
I uploaded screenshot where to check its correct build.
Hope this camera beats Galaxy S7 as thats the only reason to change phone at the first place.

Do you have an unlocked bootloader? Otherwise, you cannot read out the oeminfo partition.

---

I'm sorry I don't have it right now. Maybe I'll root this later on then or can I lock the bootloader again?

Wouldn't you need to pay a third party to unlock it at this point? Or do you keep an unlock code obtained earlier from the days when huawei handled bootloader unlocking? Just wondering. I've kind of learned to suck it up at this point since I'm no longer in the US, so the band issues only affect me when traveling back. However, if there is anyone out there with an unlocked bootloader that can share the oeminfo/know how to understand it, it would be nice to finally figure out if this really is a hardware issue or a software lock.
