Hope this isn't a noob question, I ain't touched android flashing in detail for a few years.
I have an LG G2 handset which I bought in mainland China (where I live), but is from Hong Kong as the G2 was never officially released here.
Anyway, I have got a 4G/LTE sim for it and as I expected, it doesn't work, just gives me 3G and after a quick google it seems other users have had success by flashing a rom specific to the region they will use the phone in. I have tried the 2 star/hash codes but neither seemed to work
Does anyone know my best option since I live in a region that doesn't have an official rom as such (although g2-lg.com seems to say theres a beijing rom)?
anybody throw me a few bones?! Getting desperate here!
It's early but I'm possibly relocating to Shanghai and currently have an AT&T phone I'm considering picking up at 6P but not sure my options in regards to sim cards and such over seas and there's no better place to ask than XDA. Thank you in advance for helping!
Hey, in case you still need info: I read that Huawei partnered with AT&T and China Telecom on the 6P, but you might want to double-check if there were separate releases. China Mobile and China Telecom often use a China-developed variant of network standards. In my case, I got China Mobile SIMs that stranded me on only EDGE networks, on my Nexus 7 2013 (LTE) tablet and an older Motorola Defy+ (3G/HSDPA). China Telecom even told me to go to China Unicom. You'll find most foreigners using China Unicom, partly because you can use your imported mobile no problem.
That said, if you buy a 6P in the Huawei store, or directly at one of the service providers, you'll of course have no problem.
I'm editing this to put the important thing I wrote at the top as well:
go to willmyphonework.net and select all types of nexus 6P (only 2 types) and all types of networks (only three types). You will see what sort of network coverage you get - I love that site so much.
I am by no means an expert in this area.
But I am using the 6P in Beijing and I am quite happy with my choice. However, I don't find visiting Phone stores etc easy - perhaps Shanghai will have more access to English speakers than Beijing... I have heard that some of my colleagues (non-tech) are now finding success with Xiaomi, one plus, and Huawei directly putting google services on their phones. I still end up assisting most who can't afford the iphone option and need google flashed onto their android devices.
2 things I have noted.
1. I was warned about it prior to buying, but did not fully understand. You need to follow a couple of processes to remove the problematic exclamation mark/wifi issue. You will have wifi, but it will be annoying each time to manually enter new networks each time until you do this.
2. If you root and flash new ROMS - unless you have internet access that has been redirected or vpn'ed (I don't know correct terminology, sorry) at the router level, you'll get stuck at the scanning for networks stage of device setup. You can't skip the network set up either. You just stare at a 'this will take 2 minutes' for eternity.... The fix is to find a network - like starbucks or some other western type of router set up. Then it allows you to skip the network initial set up.
I don't use China unicom, but that's because when I arrived in China 6 years ago, they sucked in terms of phone coverage. They are much better now apparently, but I have my china mobile number, and I don't really feel the need to change my set up.
If you have any worries about your phone working and which network to use, go to willmyphonework.net and select all types of nexus 6P (only 2 types) and all types of networks (only three types). You will see what sort of network coverage you get - I love that site so much.
Have fun in Shanghai! and you know ... Don't get Shanghaied
You will not get China Mobile and China Unicom LTE access with the US variant of N6P because of the lack of bands. With the international variant I have, you are free to roam the country and nearly all bands are covered. Sadly, no mainland China store will sell the N6P, unless you're willing to go to the chaotic imported phone market and seek for one - it's recommended that you get it through your US importers.
And yes, like said above, you need to root and do some (easy) steps to prevent the WiFi exclamation mark from showing up, otherwise your phone will refuse to automatically connect to WiFi even if the hotspot does have internet access.
Andy, thank you again for your advice and help in regards to the wifi problem.
USF guy, as for buying from taobao (online store) or markets, it might be fraught with difficulty for non-Chinese. My suggestion is to buy from as official as you can. Buy in HK is a good option.
The reason is because you just don't know what your getting from online sellers. For example, on my last travel to Guanzhou, I stumbled accross a phone market that was six blocks wide and long and sold every imaginable mobile phone internal and external. I very much doubt it is the only market of its kind in guangzhou and China. Simply, I don't think it would be too difficult to buy and make and sell counterfeit devices - and honestly, you might find it best to just pay the extra 400 rmb that gives you peace of mind.
You're very right about that kind of market - they might not sell fake devices these days, but the source and originality (i.e. not disassembled or no replaced parts) are questionable at best.
However, buying from HK will give you a charger that's unusable in mainland unless you purchase an adaptor separately. The only genuine option is from Taiwan, where an int'l variant is sold with mainland-compatible charger. If @USFguy is willing to arrange a trip there this would be a feasible solution. If not, then the only partially reliable one is to try and find one through US importers - at least they're more reliable than Taobao.
P.S. My own Taiwan N6P is bought on Taobao. There are many trusted importers out there, and for a device this new and this unpopular in China, there's no motivation for counterfeit.
Well, not exactly. There is one band working.
Tried Project Fi (using China Unicom) and China Mobile, most times you can still get LTE outside, otherwise, Edge you know.
I was in Shanghai last Christmas and purchased a pre-paid SIM card from China Mobile, it works fine. I also tested UniCom or China Telecom using my friends' sim card, Nexus 6P works fine with all of them: 4G LTE.
Hi guys,
I should be getting a Yotaphone 2 'yd206' next week, and the ebay seller has said it will work with all UK bands including B20 (800mhz) which is on the O2 network.
I thought only the yd201 worked with all UK bands, but can anybody who used the yd206 version clarify if it is working properly on thier UK network, particularly O2?
Thanks

Hi did the phone work with B20 (800mhz) ?
I have just ordered the phone, but have just realised that 4g may not work, unless I change network provider.

He's either lying or mistaken. The YD206 is the Chinese version which has only B1/B3 LTE (2100 and 1800 Mhz). B3/1800Mhz is used in the following countries: https://www.frequencycheck.com/bands/lte-band-3-1800
B1/2100Mhz works here: https://www.frequencycheck.com/bands/lte-band-1-2100
It should work with EE, Three, BT Mobile, Freedom Pop and The People's Operator on the 1800Mhz band. LTE won't work at all on O2 or Vodafone, and 800 Mhz rural coverage on Three (800Mhz) will be non-existent. http://www.4g.co.uk/4g-frequencies-uk-need-know/
I think there's also B41/2500Mhz LTE on the YD206, though I'm not 100% sure.: https://www.frequencycheck.com/bands/lte-band-41-td-2500
Some purportedly YD201 (800, 1800 and 2600Mhz for the whole UK) versions have been coming out of Hong Kong, but I have a hunch they're YD206s which have been flashed to register as YD201s, though they're still missing the 800Mhz band. Here's a new thread on how it's done: http://forum.xda-developers.com/yot...grade-yotaphone-2yd206-running-4-4-4-t3506293.
The one to go for, if you can find one (and they do cost more) is the Russian YD201. They sold out a couple of months ago and the current flood of Chinaphones hitting the market is because Rex Global of Hong Kong bought into Yotaphone with an agreement to pay down $43 million of debt. Dumping dead stock is a classic way of doing this - remember those killer devices the Blackberry Playbook and Nokia Pureview 808?
They don't just cost "more", they cost the same as an iPhone 6. Vastly overpriced is the term for the Yotaphone "russian" phones, actually manufactured in Singapore.
Plenty of British people already own Yotaphone in UK.
Thanks for the info, yeah I bought the Chinese version (YD206) with the snapdragon 801 processor, for 96GBP it was too cheap for me not to.
I will probably get a Three sim once I receive the phone.
Does anyone know if its worth flashing and then updating the devise to lollipop, from the pre-installed kitkat?
I ask because people have said in the past that this phones battery performance was compromised once lollipop was first updated on to the device.
I used to have a oneplus one (before I dropped and smashed it) which also had a SD801 processor, and when it was running kitkat I was literally getting days of standby time. When the phone was not in use, the battery level would hardly go down, but that quickly changed once lollipop arrived. Things got a bit better after a few incremental updates and then finally updating to marshmallow, but the battery life experienced on Kitkat was never to be had.
Does anyone know if this is the same with the Yotaphone, or is battery life with lollipop now just as good as it was with kitkat?
I do not recommend flash the device, because of problems with the e-ink screen, it happened to me, and can't solve this even flashing back to KitKat.

There are plenty of YD201s you can buy in and around Russia, both in stores and online, for around RU20,000, £250/$310. The rouble was in freefall until earlier this year so the US/European price is now much less than it was. Nothing like an iPhone 6.
I also bought a YD206 from Gearbest yesterday for £96, a no-brainer. They're selling hundreds of them until Monday, so I expect to see more community support for custom firmware and hacks. There's already a big Russian following, with a strong consensus in favour of the Lollipop upgrade for better power management etc. I'm waiting until I've owned it for a couple of months before attempting anything too adventurous.
Most people on here have successfully flashed their phones, particularly the cheap Chinese yd206 phones that don't have an option of doing an OTA.
In nearly all cases this is straightforward but if you read here, some have had problems.
My Russian lollipop Yd201 gets 4-5 hours heavy screen time on wifi. You can always go back to older ROM if you don't like the battery life on the lollipop version. There are more widgets, apps available on lollipop. If you go back to an older ROM , you should wipe user data too.
In Early 2015 , just last year, The Official UK Price Of The yotaphone 2 was 555 Pounds 699 Euros , More Expensive Than The Iphone 6 . Yes my Chinese yotaphone was 96 quid too, the dollar price quoted is dropping week on week due to the strengthening USA currency.
Thanks guys,
As long as i'm able to download my main apps, I think I'm going to stick with kitkat for the time being, and maybe in the future think about updating.
Reasons are:
1. I'm not very confident with regards to flashing, and as I'm on my 3rd phone this year due to a serious case of butter fingers, I really can't afford to ruin another phone for at least the next few months .
2. From my experience with my oneplus one, lollipop actually felt like more of a downgrade with regards to performance rather than an upgrade.
It would be great if someone was able to do a side by side test on this device, comparing the latest lollipop update with the YD206 Kitkat.
If Marshmallow or Nougat comes out on this device, I think I may be more inclined to update.
If anyone has any experiences comparing Kitkat with Lollipop, it would be greatly appreciated if you could share your experience.
Cheers
Have just received a YD206 from Gearbest for £96 and all text is in Chinese which I do not understand. Cannot therefore navigate the menu at all to select English language.
Eink screen appears dead.
I have not fitted a sim card. Will that make any difference to the language?
Try getting the correct setting for English language by first flicking down from top, first click on blue user symbol at top right, then click on the white cogwheel next on left for settings. Go through the settings, look for a symbol looking like planet (line 20). This is the language setting, click on the the top setting which is the language selection setting. I guess "English" should be in English language.
Of course it's shocking that they sent you a chinese language one.
Look out for Russian ROMs being in Russian too. Luckily I studied A level Russian.

Why are you defining yourself as a no-brainer? The YD206 just lacks of the 800MHz band, but it's still a Yotaphone 2! I'm asking because I bought one, too.

In English, A "no-brainer" is NOT someONE who is stupid, it means someTHING obvious that you don't have to even think about.
http://www.dictionary.com/browse/no-brainer?s=t
In this case he thinks it's very obvious that the price yd206 is such a good deal and he agrees with you.
I bought yd206 too.
Just got mine this morning from GearBest, so far the only concern I'm having is the fact that the response time is a little off, I type fast on my phone, and sometimes the keyboard doesn't pick up two separate taps and registers it as one, resulting in typos and a lot of backspacing.... Way to overcome this is to use one hand to type, and the speed at which you tap the buttons is not a problem.
Other than that, the phone is great. - Just having a hard time getting a screen protector on it :'(
mine works fine in english, no problem with the e ink screen, no sim card installed yet, sounds like yo might have a dud. Mine also came from Gearbest.
Have any UK users discovered the best radio files to flash? I'm using the Chinese radio but have a really patchy signal on EE. I see there are versions for other regions, worth a try?

Hi guys ive been trying to get an o2 3g sim to work in the Yotaphone 2 YD201 ANDROID 6.0.1... BUILD RU1.1.47 everything works apart from sim card, it sees it as o2 in drop down but no signal and cant find it in carrier search. It sees EE but not 02...
Ive gone into the testing mode but in the UK which is going to be the preferred network type for o2, Ive the following options....
WCDMA, GSM, CDMA, EvDo, LTE, Lte/GSM there are others including unknown..., when I change this and reboot it seems to default back to WCDMA and picking the option doesnt hold.
Can anyone please suggest the best of the networks to pick and also how to save the selection in these settings.
Many thanks
Hi has anyone any idea on saving the settings in the testing phone mode I set it to GSM and reboot but it comes back to CDMA and the GSM option is lost.
Has anyone got 02 to work with this phone as its a good phone Ive got a EE sim to work but I prefer the O2 payg plans.
Any help appreciated.
Thanks
I haven't been able to find out much about this version even though I have it. Seems like the hardware is slightly different than the other ZenFone 3 models. Front camera, proximity sensor, headphone jack, mic ,etc... are in different places. Leftovers from the ZenFone 2 stuffed in a new shell? Will root methods and roms translate from the other versions?

ASUS has no information available for this model. I bought mine from Newegg and it is listed as ZC551KL according to their information, but that isn't what I received.
It's a mystery phone.
I looked at the box again and it has both numbers listed. But nowhere in the os does it list ZC551KL.

The model number seems to be ZC551KL(Zenfone 3 Laser's global model number), with Z01BDC being the US Region model code. The difference is only in RAM size - 2GB instead of 4GB as the rest of the world seems to be getting with their Laser's. I could be wrong, but it makes the most sense. Plus, it keeps up with ASUS's odd double-model nomenclature from the old Zenfone 2 devices, which were all Z00_ models alongside the longer name strings.

Hope you are right about US version called Z01BDC, I was starting to distrust amazon cause, according to the Bulgarian Asus website (The only asus site where I found reasonably detailed specs of this ZC551ml) the US version is the only one that comes with LTE band 4 aws, which is the only band my local carriers do support for LTE network but, using the phone right now I do not get any LTE signal at all, so I thought maybe amazon sold me an international version by mistake...
Does anybody have confirmed that this supposed US version (Z01BDC) works with LTE band 4 frequency? I've asked to Asus by mail but it seems a pretty complicated question to them... who are actually the phone makers...

I can confirm that the phone works for AT&T's 4G(not sure if LTE) where I get roughly 30Mbps download on my current AT&T-using provider, with it maxing at 40Mbps down/17mbps up. In addition, the FCC listing of the Zenfone 3 Laser is specifically for the Z01BDC model.

Thanks for the confirmation. As regards mine device couldn't get it to work with LTE at all unluckily.
One curious thing is that when i did try reflashing through adb-sideload to see whether that manage to solve the problem, phone was OTA updated accidentally, couldn't get it to work; in fact the only way i could reflash it was by SD card update, I thought about flashing from fastboot but it doesn't seem quite simple as motorola to me. (lack of knowledge about droidboot, boot, asus system partitions, and so on..)

oh my god don't get the 2GB Laser. It's awful. ASUS' ZenUI takes up 1.5GB of the 2GB in the phone. And because of Android's RAM management, you can barely open two apps at once if you're lucky. I returned it real fast and got myself the 4GB Zenfone 3 instead.

You're over exaggerating. It's pretty fast and fluid in my case. I have disabled all Asus apps that I can (I think there only a couple that you can't disable) and I am using Nova Launcher. It's very smooth. The fingerprint sensor is also lightning fast

Hey guys I've had my Axon 7 for almost 2 years now, I am planning a trip to Tokyo for just over 2 weeks at the end of August and want to be able to get a sim in Japan and use my phone as normal. Now our Axon 7 u supports 3/4 of SoftBank lte bands and 2/3 of the other bands it needs. So this option doesn't seem too bad.
Now getting closer to my question.
International or us versions of the a7 all have the snapdragon 820 which contains the modem. This same chip is available around the world including Japan. So
Does the snapdragon 820 have different versions with different modems? Or is the software the reason only certain bands are available in different versions of the phone.
If the software decides which bands are available is it possible to edit it to unlock any bands I may want when I am in Tokyo this summer?
I am on unlocked bootloader twrp etc. and have used lineage os and other ROMs right now on a stock based room rooted
Any help and knowledge is appreciated. I googled around a bit and didn't find much on the subject
Simply having a chip that supports a band is not enough, it needs antennas that are properly modulated and shielded for that frequency.
Even if you were to patch the modem to enable a certain band, you would most likely not get reception at all or cause interference on other channels

I'm guessing you aren't too aquaintanced with custom ROMs and that kinda stuff for the axon 7. lemme explain.
There are 3 versions: A2017 (china), A2017G (Int'l, the one used in Japan i think), and A2017U (US). All of them have different modems.
The updates for each device all come with different NHLOS.bin files, which are the modem files. If you flash the U file on a G you won't have any signal. Sometimes you can even wipe out your IMEIs.
But why do you need LTE for a 2 week trip though? You'll get phone signal and data anyways...

I know all about the different versions of the phone, I've been around here for a while. My first question was simply if the 820 has different versions with different banded modems. After reading your reply I'm still not sure. Like I said I know about the different versions of the phone and the fact that they have different modem firmware. My question was hardware related, based on another guys reply it seems not likely it's there antenna that is the deciding factor in what bands can work as far as hardware is concerned which obviously means there is no possibility of unlocking any bands

What I mean is that installing different modem firmware basically makes the modem inoperable. hence, there are key differences between the models
I'm in Tokyo right now and get LTE on Docomo via band 3, which doesn't seem to be advertised anywhere. I was quite surprised! Speeds have been great!
Technically, it can work in Japan. It will get LTE in urban areas and a mix of LTE and HSPA+ elsewhere. From a practical point of view, the garbage radios in the Axon 7 are a serious problem if you're roaming. Hopping around on different bands and carriers causes the radio to constantly die, lose data, or lock onto the wrong cell tower. You'll have to cycle airplane mode frequently and you can't count on incoming calls/texts working.
I haven't had time to try LineageOS in Japan yet. It seems to have fewer radio problems so it might do OK.

Hey, I use a American Axon 7 in Japan with no issues, if you use any MVNO sim that uses NTT Docomo Network you should be fine, for example BicSim, IIJMio Travel sim etc.
