No the US doesn't use B20. If changing firmware doesn't offer B20 then its may be possible to use the QPST tool to open the band.
I would try all working compatible firmwares first. Plus drive to someplace where other people absolutely have B20 before doing anything drastic.

You can try OPO guide: http://forum.xda-developers.com/oneplus-one/general/guide-unlock-aditional-bands-qualcomm-t2877031 but I dunno if it works or not so don't blame me if you'll break your phone.

Thank you very much! I read the tutorial, and is very interesting , although I have sufficient knowledge to dare to do it, I 'm afraid to leave my phone like a brick. Need to unlock the band 4 ( aws ) but I worry that the phone does not work anymore.
Has anyone tried this?

X720 with USA LTE Bands

I have an x720 and have been reading on how to unlock band 17 and 12 for at&t and t-mobile LTE service. As of right now I have some limited LTE service on band 2 and 4 (at&T) but it leaves much to be desired.
I see everyone here flashing the x720 firmware to get their x727 bootloader unlocked and then flashing back to the USA Firmware to get their LTE bands back. Is the reverse possible for the x720? Can I flash the USA firmware to get the LTE bands? Will this re-lock my bootloader?
I tried flashing the modem fix from https://forum.xda-developers.com/le-pro3/how-to/flashing-guide-roundup-leeco-le-pro-3-t3511901 on my x720 and now my sim card is being detected even after a wipe and reflashing my rom. So I'm assuming i'm gonna have to go back to stock firmware anyway. I've been a long time flashoholic and modder and I'm dedicated to getting this to work for us x720 people in the US.
What about this guide for the le max 2? I've heard all qualcomm devices can benefit from this procedure:
https://forum.xda-developers.com/le-max-2/how-to/guide-unlock-bands-leeco-le-max-2-fix-t3439154
UPDATE: Fixed no sim error after flashing x727 modem.
Downloaded a stock version of the Chinese Firmware and extracted the zip, then booted into fastboot and flashed the modem. You need the NON-HLOS.bin file. Then run "fastboot flash modem NON-HLOS.bin" and reboot! Voila. But still no band 17
I think unlocking the bands is not as easy as just flashing a ROM. When I was investigating OnePlus 3T, there is a long thread about it and basically band unlocking requires a lot of tools, some from Qualcomm and not easy to get, and a process that is not for noobs, not even for "professional TWRP flashers" but hardware-engineering-mode noobs anyway.
You can have a look here on how complicated it is (OP3T forum):
https://forum.xda-developers.com/oneplus-3/how-to/guide-unlock-additional-lte-bands-t3519563
Initially I liked OnePlus3T more because of optical stabilizer in camera, but lack of bands (or better to say, their separation into North American and European version) was a no-go for me. I need bands 2, 3, 4 & 20 and there is not a from-factory OP3T with those 4 bands in one device. Band unlocking might be possible but I would not risk messing with a $450 hone to get bands 3 & 20 unlocked on NA version. So I went with Le Pro 3 X720 and I am a happy camper.
So unless you know what you are doing, or are an adrenaline junkie, I would not mess with band unlocking.
I would absolutely LOVE to see an answer and/or progress on this EXACT scenario being made. Both myself and my wife have Le Pro 3's because of the universal network band support and INSANE performance of this phone (I've literally never seen such a performer with such large battery AND ridiculous band support at such a cost effective price) ((I bought both for $249 each).
I would LOVE to be able to buy the Chinese version with the 6G of ram, and then unlock the NA bands, specifically and especially bands 2,4,12,17,and 20 would be needed for our phones. So I'm super interested in this. You want to do exactly what I'd like to do, although you have the Chinese phone in your hand and I don't.
Both of our phones (x727) are bootloader unlocked, rooted, and TWRP recovery installed on stock .21S done by myself. So if there's anything I can help with, let me know.
Are you rooted? Download Network Signal Guru and lock bands under the menu in the top-right. See what LTE bands are listed there.

Yeah I've read through that process before I posted. I don't know if I'd call that "hardware-engineering" just because it puts a device into serial mode and communicates with NV memory.... I used qualcomm's boarddiag tool to unbrick a nexus 5 with the serial connection... doesn't seem any different at all actually :fingers-crossed:
I'm not ruling that out as a method, however I think we may have hope to do it easier. The x727 has been many times on this forum successfully flashed to x720 firmware. Everyone who did this reports the loss of usa bands though i have not seen confirmation that they GAIN additional chinese bands. That indicated to me that the baseband/modem is the only difference between the x727 having band 12 and the x720 not having it. We just need to tweak the x720 modem with the bits from the x727 modem.
https://forum.xda-developers.com/le-pro3/how-to/flashing-guide-roundup-leeco-le-pro-3-t3511901 In this thread there are several users that say they successfully flashed their x720 with x727 firmware and had full LTE, however there are also users reporting flashing the x727 firmware gives them a "no sim card detected". The latter was my experience. I believe this has to do with the switch from dual sim cards to single sim cards, i tried several build.prop tweaks to try and resolve with no luck.

From my x720: 1, 2, 3, 4, 5 ,7, 8, 20, 38, 39, 40, 41
I think that's what is officially listed online. Most people in the US would be fine with this except the notable lack of band 12(tmobile) and 17(at&t).

Then let's get started! Looks like all we are missing from your list is band 12 and 17.
Can you get me a dump of the baseband? I'd like to start digging into it and compare the x720 and x727.
I may try the qualcomm tools if I get the chance this weekend. If I have success and don't brick my phone I'll do a write up specifically for the LP3...

Sure man, I'm totally down to help however I can. I've never dumped a baseband before (never had the need) so the process eludes me, but I'm more than happy to perform whatever steps needed to do so.
Just give me a detailed rundown on how to do it or what tools/commands to run and I'll have it done for you ASAP. You can privately message me if you'd like, makes no difference to me. Give me the knowledge and I'll give you the love.

I'll shoot you a PM in a bit.
As far as progress on this goes, I'm trying to enable them via the DFS guide that was copied over here: https://forum.xda-developers.com/le-pro3/help/unlocking-bands-t3565979
I'm going to see how complicated it is and if that negates the time we are spending here first.
I am having the exact same issue as the OP. Any movement on a solution. I am willing to help/test. Not a noon but far from an engineer.
Question, how do I unlock the bootloader now? With the us servers down I can't get twrp files. Also, I can't unlock the bootloader with adb. I'm trying to flash Lineage OS onto my x727. All help is appreciated, thanks.

4G Bands Elephone P9000 US Version

Hi, I hope that you can help me, please. I have a Elephone P9000 US version, I bought it a few weeks ago, and it works good, the bands for 4G B2 and B4 works perfectly.
Now, my problem is that I have updated it to Android 7.0 with the ROM P9000_20170418 that I found in the forum and now the bands B2 and B4 and the others that belong to the US Version have stop working. Now my Elpehone P9000 works as if was the Europe Version.
I need help to see what can I do for the restore the bands of the US Version, I don´t know if you can share me the original ROM for the Elephone P9000 US Version or how I can restore the US Version bands.
I hope you can help me, I would appreciate it very much, Thank You.

Converting 7T Pro McLaren to International McLaren

I couldn't find a post that clearly stated or answered the question. So the question is, is it possible to flash the international 7T Pro McLaren stock rom to the 5G TMobile version if you don't care about losing 5G?
Not at the moment,no
No you cannot, the MSM tool is hardware specific so at this point there is no way to get around it. I wish we could get a working TWRP for the 7t pro 5g McLaren. On my 7 pro I dirty flashed international system of T-Mobile stock room through TWRP and had dual SIM support. I then added all the bloatware I actually want from T-Mobile and had no problems. I'm hopeful we might, one day, get to do that to these!!!

Thank you for your input. I appreciate that you elaborated on the setbacks. I am also hopeful that we will eventually have twrp and an msm tool. I love this phone and will wait as long as needed.
Thank you for the question. and answer. I was wondering this as well. One day we can get rid of the TMO stuff.
Dang. I just ordered the 7T pro McClaren *yesterday*. I didn't know we couldn't unlock the bootloader until after 60 days. Guess I'll just ask nicely after it arrives...
Any update on this?

Thankyou so much for reply.
But I think it's the same chipset as the Global one.
Different network chipset.
