Hey guys, I am a total noob when it comes to android, so please don't be upset by the noobish behavior. I just transferred over from using apple iphone for 5 years to the LG G2.
I installed twrp and clean rom xe 1.3 onto my LG G2 from AT&T. It comes rooted i suppose since i have access to superuser. Is my device now unlocked as well? I will be traveling to Europe next year and was wondering what I need to do in order to unlock the device.
Thanks in advance, and please correct me if I am wrong on anything I have mentioned so far.

No. Sim unlocking is seperate. I used: http://www.cellunlocker.net/. It ram me $10.
Now, if I misunderstood and you were referring to bootloader unlock, does not yet exist nor is needed for installing roms
Thanks for the info! I used to do software unlock using cydia on Iphone, but I guess that android does not have the same functionality.
May want to check this thread.

Hi there,
I would love to buy a S5 Active in the U.S. an use it in Germany. Since it is looked to AT&T which we don't have in Germany, I want to root it.
For the past 2 days I did some research in this forum. It turned out that it's more complicated than I thought.
My English is not that good, so before I actually buy a phone I want to make sure that I understood everything... more or less.
So, if I get my hands on a phone with 4.4. or 5.0 on it, there is no problem to root it because there is no blocked bootloader, right?
I don't know though which ROM I should use in that case? Which one runs best on the S5 Active?
If the phone is running on 5.1. there is the problem with the locked bootloader, right? In that case I use this guide?
If I get a phone that is running on 6.0 or 6.1 I need to downgrade to 5.0 or 5.1 using this guide and the just do one of the two steps above accordingly?
Does that mean it doesn't matter if the phone I buy runs on 4.4, 5.0, 5.1, 6.0, or 6.1? Can I root in anyway?
Thanks heaps for your help!
Cheers Sam
you dont need to root it for international use. If its not bound to a contract with at&t anymore, then youd just need to contact at&t to have them unlock it for international use. if youre worried about the cost to call at&t, just get the textnow app, get a usa phone number and call them via the app over wifi for absolutely no cost. or, if your worried about your english being a barrier, go to idoneapps.com and they can unlock it for you for $35. I unlocked 2 G900P (sprint S5) with them.
Hi, thanks for the quick reply.
Well, I also though about just getting a unlocked one or to unlock a locked one. BUT then I have all those atnt Apps that I can't uninstall.
So I figured, the only way to get rid of them is to root the device right?
Cheers, Sam

youre correct, those specific apps do require root to remove. Then youd want something like Titanium backup to get that job done
I havent found anything so far that will show me how to root a G870A ACTIVE on 5.0 (OF3) all these links go to methods that show how to do it on a G900 (non active) if anyone can point me in a direction that would work i would much appreciate it.

i think the bootloader is still locked on that device. Not getting much love from devs either. Not sure there is a solution for this, sorry good sir
Well I received the SM-G780A today. It is not locked to AT&T anymore so I can actually use it without rooting it.
However the preloaded apps are just a pain. So I am thinking about rooting it anyway.
The Android Version is 5.0 and the Kernel Version 3.4.0-4443965. Do I understood it right that the bootloader is not locked in Androit 5.0 yet?
What's the best way to root it and is there any chance to get a rooted Android 6 running on it?
Cheers Sam
Hi!
I am sorry if this has been asked here before. I'm fairly new to this kind of stuff.
So I'm a foreigner living in Japan. Due to the allure of local warranty, I decided to get the Axon 7 (A2017G JPV).
It has been months since the last Nougat update came to other A2017Gs but hasn't arrived on the A2017G JPV. So I thought, may be ZTE Japan was just taking a longer time, etc. So recently, I decided to contact customer support. And their answer was unclear at best. They were apparently still deciding if they would release a Nougat update for Axon 7.
So here's my question. Considering that my Axon 7 is also A2017G, is there a way for me to install the latest A2017G European ROM or any other A2017G Stock ROMs for that matter, without unlocking my bootloader and rooting? And get OTA updates from A2017G European? If so, can someone please kindly point me in the right direction, I'm getting a bit lost.
If that isn't possible, is there a way, to install the stock A2017G ROMs (aside from JPV) and then relock the bootloader afterwards?
Please help me. Thank you.

Hi
Thank you for replying so quickly.
Please bear with me as I am still a bit confused.
The link you gave mo contains Factory Images for the A2017G, right? Therefore, I should just put the factory images (zip file), into the root directory of my SD Card, and update via settings (no need to unlock bootloader or root, right?)?
My A2017G (JPV) is now on A2017G JPV1.0.0B03.
Which factory image should I use?
Thank you very much.

Are you mad?!!! This won't work as the signature's don't match.
At best you end up with a failed update, at worst a brick...

Considering @ultramag69 said, do you think I should still proceed with this?
I don't think you have to the same radio firmware with all the G version out there.... If you dare to try it probably you will end up bricking your phone.... So don try. Unless you are sure can warranty claim it if it is briked
Unfortunately this region locking thing came in, sometimes it's different hardware for different regions but mostly it's to stop the grey import trade...
Due to this it is a requirement to unlock your bootloader if you want to flash other region/carrier roms, which again is a trial in itself...
If you do wish to try it, make sure you have a flashable version of your FULL stock rom, not an OTA - the difference is an OTA is a patch, usually of a few hundred Mb or so to update parts of your ROM, the full ROM is a stand-alone installation that will completely replace the current ROM.
Generally this will get you out of hot water but be aware this is also not 100% guarantee...
It will probably also delete all your data, back up first....

What I'm confused about is he's not asking to flash A2017A/U firmware (where region locking comes into play) on his device, only another country's A2017G fw so why would he need to unlock bootloader? It's still fw for the global model if I understand correctly.

I'm on your side - the modem file might be different, but since the hardware is the same, it should work. Maybe the modem file has improved signal stuff for Japan, but it's extremely improbable considering ZTE's craptastic devs...
Also, what could be the worst thing that could happen? Here are the possibilities:
- Works: enjoy
- Installation failed: Should fail before even changing files anyways
- Soft brick: get to recovery, download full update zip, install, wait for Nougat
- Hard brick: "I woke up this morning and it was off, doesn't boot anymore, I want a replacement"
And if the modem is too crappy you can always go back to Japan's firmware
I believe that the Japanese version is different from the other G versions, at least on the modem level. Japan uses some bands that are not used by any other country in the world, so unless ZTE Japan decided to release the G model knowing that it would have some connectivity issues on all Japanese carriers, the Japanese G model must have at least a different modem.
Bold = band is present in the global G model
KDDI: CDMA BC0 / BC6, LTE 1/11/18/41
NTT Docomo: UMTS 1/9/19, LTE 1/9/19/21/28
Softbank: UMTS 1/8/11, LTE 1/8/9/41
I kinda get what you're getting at after looking further into the models. Basing off the spec sheets, Amazon JP has the exact same A2017G TD-LTE with matching bands sold by ZTE. Whereas on the ZTE JP page, it instead matches the bands of something named Axon 7 TD-LTE JP (couldn't find model number, but sounds like OP's A2017G). This has over half the exact bands available on A2017G, additional UMTS bands 6 & 19 and one CA band.
I think someone in another thread previously mentioned about potential signal issues with the Axon 7 being sold in Spain after flashing DE fw. Looking at their spec sheet, it appears to have a few bands missing, may have additional bands, but it's hard to tell since only the frequencies are stated. Could just be anecdotal as you'd think with the greater range of frequencies, it shouldn't face those issues. Anyways this is a separate matter, and potentially an apples to oranges comparison.
Thank you all for your advice and insights.
I figured, damn all worries, and just used the recovery mode to flash the update.zip.
Lo and behold, it was updated with seemingly no issue. Even tried if my mobile data would work properly. And it did.
Thanks everyone!

Yeah it was nonsense, they are both a2017Gs anyways
We're all a bit mad though, flashing stuff on a 400 dolar thingy...
ive got the A2017 Chinese, bought from aliexpress. Ive rooted and installed the twrp flashable B15 from @djkuz, but the nougat firmware is awful for my DoCoMo phone reception (in far regional Nagasaki). So i need a method to either flash the modem for A2017G (not sure which B# release), or wait for the next chinese firmware release and hope for the best. Any suggestions or experiences to improve my reception? Is it the modem?
Thanks for all the contributions to this thread, as it has got me in the right direction.

Hey I know this is an old thread but I thought I would poke in and add my feedback. I also live in Japan and have the A2017G. I bought it because it was the only phone on the market at the time that [supposedly] supported Google Daydream. Later I realized that only the US version actually worked with Daydream. Later on support was added to European ROMS (when upgraded to 7.1.1). But for some reason the Japanese ROM, despite being 7.1.1 would say 'Incompatible Phone', even when installed manually. I contacted ZTE's customer service, which was terrible; all they said was "we don't know when it will be supported". This was about a year ago, so this week I just got sick of waiting, found the German firmware (A2017G-N-B10), installed it and everything works fine. The radios have no issues, and I was able to download Daydream right from the marketplace.
Thanks for everyone who contributed to this thread!
Dear XDA Members and U Ultra owners,
I just recently purchased the U Ultra sapphire glass edition 128GB Dual Sim and I would really like to install the deodexed firmware with root that's available. However, in order to flash that firmware, I think first I'd need to unlock the bootloader and get TWRP? Is there a current guide on how to unlock bootloader and side load TWRP?
I'm familiar with the whole process just haven't seen a guide for this phone as of yet, or at least haven't looked well enough to find one. I thought I'd ask here and it would make it a little bit easier.
I have unlocked bootloader on many phones before and I was wondering if it's the same process for this phone... Do I have to unlock it through HTC Dev? And what about TWRP, where can I find it for this phone? The website? Or is there a custom build version for this phone since its not that popular?
Any and all help will be greatly appreciated.
So I guess I found out where to get the recovery from... Does this work with the dual sim version? https://forum.xda-developers.com/u-ultra/development/recovery-twrp-touch-recovery-t3558540
I guess the only thing left now is the bootloader. I could use some advice on that.

I managed to figure it out. I attempted to unlock the bootloader through HTC Dev website which was a fairly simple process as I've done this several times before. I'm just waiting on the email for the unlock.bin file and for some reason it's taking its time and I've not received it yet, been well over an hour. Odd isn't it? Or is this normal?
Now I guess my only question is the S-on/S-off.
I remember with HTC M9 and 10 you had to use sunshine to s-off. Is that also required with the u ultra?
Sorry, forgot to make an update letting everyone know that all of this was taken care of successfully, I'm currently rooted and on a deodxed 8.0 Rom with magisk and twrp. Everything going great!
hello and thank you for this monologue ...
I am on the site of HTC dev but in the choice of the phone there is no U Ultra, is it normal?
Would it be easy to tell me more about the S-off method, and more, please?
So truth be told I have a G5 plus that nobody wants, completely wiped and restored and still has a good battery.
Now here's my question, it's a XT1687 version PVTB w/ the AMZ variant. I did try the traditional method of unlocking the bootloader via Lenovo and was informed I could not. Fine. Does that mean I am SOL upgrading the ROM to a newer version of Android? I have read some conflicting opinions but I am not an expert with phones.
So just to clarify could one of you experts here tell me one way or another if it's at all possible? Why I ask is I would like to learn how to do this better and if I should brick this phone it's not the end of the world.
Thanks again for your help, believe me I did try to solve this myself.

I don't believe there is any other method to unlock the bootloader.
