Getting a new M8.. Help needed - One (M8) Q&A, Help & Troubleshooting

Dear all,
I am living in India and I'm planning to buy an M8. Since the phone is officially not available anymore, I am getting one from eBay, which is a US imported one. [ Linky ].
Though the seller is saying that 4G is working for Indian SIMs, I am a bit suspicious. I am using Airtel 4G SIM ATM and am planning to root/install new ROMs. Suppose if the phone supports 4G initially and after flashing ROM will it affect the bands? How do I find that out?
Any help is appreciated.

flashing roms won't touch the radio ( the bands that device supports ) it will be intact
so if the stock out of the box status support your carrier network then any rom will work just fine

Thanks mate. I believe the seller himself has worked around with ROMs to make the 4G work. If I flash a new ROM it won't kill the phone right?

Flashing rom doesnt change the LTE band . If its US imported phone then IMO only verizon supports indain LTE band . Even that model only supports one band not all and m8 is not volte supported . Airtel calling will be fine as it use rollback to 3g for calling .
I am from india too . Market price for 4g m8 is about 10 k . These phone (mostly) are not new , they are refurbished . I have bought 5 m8 from ebay .
Hit THANKS if somebody help you

Thanks for the reply mate. I don't care about refurbished ones, as I am buying this only for the audio. Could you please tell me how to identify a 'refurbished' phone?

Check sim slot..it will be of different colour as comaperd to housing .
Match imei on sim slot, box and phone real. All should be same.
Charging port/ audio jack should be in new condtion, no used sign in there .
No quality seal ( i have seen some white seal on refurbished) .
Bootloader menu ( should be s-on and locked ) . If opened or used then it will tempered as all varaint comes as international unlock so need for software programming.
Hit THANKS if somebody help you

Additionally, if it is the Verizon version, it will possibly have the back cover replaced. Verizon version M8 has the Verizon logo on the back like this, which when resold as "unbranded, etc." will have the back cover replaced with one without any carrier logo.
In this case, the model number on the back will often not match what is shown in fastboot getvar all.

Does the 'dual radio' on Incredible 2 really useful?

I'm tempted to buy this handheld, but I must admid that I've been saving up for the DHD. I found that the dual radio (GSM and CDMA) of the Incredible 2 will be very useful as modems. Need feedback.
this phone supports both for global capability and also comes in handy if you want to unlock it to work on a GSM carrier like T-Mo. Not sure I fully understand your question.
your question isn't clear , do you mean by using it as a modem that you want to do tethering ? . if so , GSM carriers also allow tether . Please note that tethering is subject to additional fees ( i read that somewhere ) although you have unlimited plan ??? . i don't live in us . so ,better you clarify that point before buy with your carrier .
you said you want to buy DHD which i think is a GSM Phone ,( i.e you are using a GSM Carrier ,NOT CDMA ) . this phone have good Dev community as a CDMA Phone , But Very very Few Roms for GSM , basically you would be stuck with the Stock firmware if you want a stable GSM Rom , note that the stock Rom is built for Verizon ( i.e many parameters will refer to Verizon network )

[Q] Stupid question EU on US

Hi all,
I've bought a EU M8 mobile...I think it's EU as I bought in Dubai.
Sooner I will relocate in US and I've just realised that my mobile potentially could not work there ....is this true?
How can I check?
Thank you in advance for your help.
If it's eu, it'll work fine but I don't think you'll get LTE. I may be wrong. But it'll work
As stated it'll work fine, I know from experience! (Not re-location but hey). I'm not sure about 4G/LTE though.
Thank you and sorry for the delay.
I can't understand why it should not work 4G/LTE.
Are you saying that HTC makes two different model with different frequencies/bands??!?
my phone is actually completely unlock and not branded. if i buy a new US sim cards why do you think that 4G/LTE wont work?

HTC does make two different models(GSM & CDMA). I don't think the frequency/bands on the GSM phone you have will matter much. As I understand it the Qualcomm RF360 Front End solution chip has 40+ bands on the chip exactly for this reason. It makes it more "Global", it should already be capable of receiving 4G/LTE on most frequency/bands available in pretty much any country.
I think the only thing that perhaps influences it is carrier specific requests to lock to certain bands... Probably for roaming purposes and to get more money. But a carrier free device like you have shouldn't have a problem to work(Even LTE) in the US if you insert a local SIM card for it.
But that's just how I understand it from a quick look up I did some time ago, can't know all the details though. You could probably read up more on it for yourself if you're interested.
Qualcomm RF360 front end solution
thank you BerndM14!!
you clearly explain what was in my mind.
i can understand if some locked/carrier phone could have some problem but i would be surprised to discover that a brand new mobile such this will have issue to work overthere.
i'm searching the web as well but it's quite difficult to find clear answer.
i'm just wondering if in case there is some "lock" if those are bypassable flashing a different radio rom
sorry for my bad English
maybe I m wrong (but that is what I have to say as Vodafone Germany employee to my customers)
the One M8 will work fine with US LTE bands cause the EU and the US M8 are technically the same.
that's also the reason why it´s works not with any European LTE network outside Germany

Volte

Hi I have Taiwanese HTC 10.. s-off.. inlocked bootloader.. converted to wwe...runnung latest 1.90 firmware with viper rom..I am from India and my service provider JIO fully supports VOLTE
I cannot use VOLTE , and in the phone option, their is no choice of Volte..
Any ideas how to activate Volte calling on Htc10.
I think /system/customize/ACC/default.xml needs to be modified in order to do that..
Need help.
My understanding is WWE doesn't support VoLTE.
It is framework dependant and not just XML editing. You would need to flash back to the RUU for your country/market.

If you can, load US unlocked code, 1.91.617.1. It has August security patches, as well as VoLTE and Wi-Fi Calling.

This may not work due to both a CID/MID mismatch and differing radios for his market.
I'm curious to see if it would though. Radio/framework mismatch may leave it not functioning on LTE properly.

Frankly I don't believe flashing US firmware, radios or OS will work. US software is optimized for our bands and carriers, not yours leaving performance questionable.
Is your 10 a lifestyle or regular HTC 10?
Your best bet is to flash the most recent software for your market and if that allows VoLTE them great and if not then not much you can do.

Mine is regular HTC10
Can any one Provide with the HTC engineering Code? If you can provide with that code, than enabling VOLTE is possible. Just few settings to be changed and VOLTE can be activated.

I had a chat with HTC customer care just now, and they said HTC 10 won't support VoLTE in India. They say the phone does not have the hardware specifications for Jio VoLTE, or even the upcoming Airtel-VoLTE.
You should have told that uneducated fool not to lie
SD820 includes GPU, CPU and Radio hardware inside it, it is not an independant hardware.
Those bastards just don't want to upgrade it
U should know that in other countries VoLTE is supported.
In Australia it was enabled via software update for Vodafone customers (pls confirm this fact urself)
https://www.reddit.com/r/Android/comments/5tce24/htc_10_in_australia_seems_to_be_getting_the/
unless the VOLTE in india is so different to other country it is hard to imagine why it will not work except HTC don't want to include it.
anyway did you try the Jio4GVoice app?
@DummyPLUG Yes. Jio4GVoice app is working.
I think we should comment bomb their FB and Twitter
What say u guys?(Indian owners)
Other country users also please support our cause and question their software support

Yes. I had a chat with HTC. they are talking rubbish saying its a hardware issue. what pisses me off is we pay so much money to these companies and they neglect us. even cheap Chinese phones got volte support. but HTC developers are lazy to include a volte option. what a shame.
I had a chat with HTC customer support today and I got a positive response regarding VoLTE update
I have a htc10 from Dubai
Took me 15-20 days working on it with diff rom and radios finally
Now my jio(India) sim is working on it
It does not show Volte on the top but call, 4g and sms is working

LG G8 T-Mobile signal issues

Hi,
I would really appreciate if someone could help me with my LG G8.
I bought it off ebay , the phone is on T-Mobile version running Android 10 with the software version G820TM20i .
Since the phone was not available to buy in UK, i've ordered it from US .
I am using it with a EE sim card which is supposed to have the best network coverage in UK , but still the signal bar only shows 1 or 2 lines from 5 ( 5 being max strength ) .
When using the SIM card with another phone ( S10+ ) originally bought from UK I am not having any signal issues.
My question is : Could this be a problem with the stock ROM being a US version ?
I am thinking of flashing another ROM probably one from Europe or even UK, but unfortunatelly I don't know which one is the best.
Could anyone advise me ?
Thanks.
I have the same issues. Mine is a factory unlocked G820QM (US version).
Not working well in Singapore.
On the network with the best coverage just 2 bars and just UMTS.
With another network 3 bars and LTE but ... no mobile data.
Not easy getting these US phones to work overseas ...
It should be easy, i used to flash my lg g6 and lg g4 with ROMs in order to fix this kind of issues, with the help of the DEVs from here.
It's so sad that this forum is no longer that active like it used to be .
The G6 and G7 was also sold in Europe, SEA and so on. So flashing to other locations would be possible.
The G8 was only sold in the US, Korea and Canada. Still possible to flash to be able to work in the UK?

Question Hey guys one guy is selling 9pro only gsm working chinese rom should I buy it .

Hey guys one guy is selling 9pro only gsm working chinese rom should I buy it .
Can you elaborate what do you mean by only GSM working? Or by GSM you mean only GSM for calls and text or only edge {E} network instead of 3G,4G,5G , the only reason I can think of is that back when I was there China Mobile was using TD SCDMA and is this a TD LTE phone? Thats what you meant? Or by GSM only you mean GSM is working wifi not working? Or a software bug?
depends on the price. let me know cause otherwise i will
