WiFi Country Code - One (M8) Q&A, Help & Troubleshooting

Hey Guys,
I'm running my One M8 on ATT, S-OFF, supercid. I decided to update to the newest international firmware and the only issue I seem to be having is WiFi. It is now setting my WiFi country code to EU. Is there any way to permanently fix this?

EU just adds channels 12 and 13, so even without changing it there should be no WiFi issues.

Hi guys,
Anyone with the latest EE firmware and with wifi calling working know how to extract the code so we can get it working on non EE firmware?
Cheers

Frequency bands

I own the HTC One M8 16Go gold Asian version, phone is rooted with ElementalX kernel but stock rom. My phone works with 700 (b28)/900 (b8)/1800 (b3)/2100 (b1)/26000 (b7). I had the TW Mobile carrier in Taiwan. I want to add frequency bands to enable 4G LTE in Canada. Most carriers work with 1700/2100 (b4).
So how to add these frequency bands?
You need s-off ($25 by sunshine app) to change radio baseband (which changes band support).
You can flash AT&T or T-Mob US firmware to change to the corresponding baseband (both support Band 4 LTE). Or the correct Canadian carrier version's firmware; if you want to, and can find it (ATT and T-Mob are probably easier to find).
But you should also verify what bands your carrier uses for 3G, and that the new baseband supports it.
In my experience, AT&T has past or current associations with some of the Canadian carriers (still has partial ownership in some); and the networks share a lot of similarities. So AT&T firmware may be the best bet.
I installed Sunshine app but can't perform any test because it says Xposed Framework has been detected. I delete it but still the same error.

Try to restore the stock ROM, then root and run sunshine.
One thing to keep in mind, its not guaranteed that you will have LTE even with the proper baseband radio firmware. I've seen a number of folks that were not able to get LTE, even after s-off and flashing the proper radio firmware (that supports their carrier's LTE band). Don't know the reason for this, and never saw a solution. But just want you to be aware, in the event you spend the $25 on sunshine, and still can't get LTE.
But the fact that the Canadian networks seem to be very similar to AT&T, leads me to think the AT&T baseband radio will work for you. Not based on any specific/exact experience, just a hunch. So don't come and yell at me, if it doesn't work!

HTC One M9 volte

Hello devs is there going to be a rom that will work on volte? I'm running an HTC One M9 AT&T with dev edition ruu right at this moment but I have flashed everything from venom to insert coin to lineage, aicp, more, beanstalk...... None will work on VoLTE I have to either run 3g all the time or turn 4g off while I'm not using data it's very annoying cause I forget. I have been looking for a solution Nada. Please help if anyone has any suggestions. Thanks in advance!
The dev edition firmware doesn't support VoLTE. You need to use a branded firmware which has VoLTE enabled. It doesn't matter which rom you use as long as your firmware doesn't support this feature.

Well the one I have is working its a dev edition but when I flash a custom ROM I have to turn off 4g to receive phone calls
As said before, the problem (normally) isn't which rom you flash. It's which firmware you use. If you convert your phone e.g. to the AT&T branded version and flash e.g. ViperOne, ICE or Leedroid, afterwards, you can use VoLTE.
The dev edition (just like the unbranded European and the unbranded Asian version) doesn't have VoLTE enabled by default. The stock rom of said firmware versions switches to 3G automatically as soon as you receive a phone call. I'm not sure why that feature doesn't work on your phone as soon as you flash a custom rom. From my own experiences, it's working fine on e.g. ViperOne.
I can confirm flippy, the wwe is capable of volte as I get it on O2. It would seem here in the UK you need a branded firmware to get onto volte BUT if you debrand the phone to wwe it can volte on any network.
For example ee say that only ee branded phones can use their volte, which is true because all other branded phones can only use 'their' networks volte as it is preprogrammed and cannot be changed by normal means.
If you root, change cid and debrand with another firmware then you can use any volte as it depends on the sim card in the phone.
On HTC devices custom roms just piggy back of the firmware that is pre installed. The rom is just another form of user interface for the device so in theory the rom 'should' be volte compatible providing the firmware installed before it was capable and unbranded. Remember that only "branded" devices can use the network unless its unlocked wwe. So if you had an att firmware and you flash a custom rom onto it then it is no longer branded and shouldn't be allowed.. If its previously unbranded and you flash a rom then it should be allowed. Needs testing..
A long winded way of telling you bugger all but I hope it makes the carriers requirements a tad clearer..

Actually this is not true, or maybe your wwe it's actually not wwe.
I have s.rom custom rom, if I have 4.28.401.3 firmware volte isn't working(the function disappear from settings)
If I flash the Orange UK firmware(4.19.61.1) the VoLTE is working, and no I don't have Orange UK sim, I tested with Orange RO and Telekom RO.
Flashing a custom rom doesn't debrand the phone. The debranding process consists of
getting S-OFF
changing the CID to one that belongs to either SKU 617 (dev edition), 401 (unbranded European), 708 (unbranded Asian), 709 (another unbranded Asian) or 710 (unbranded Australian)
flashing either a RUU or one of Sneakyghost's firmware packs that belong to the CID you chose before
And you don't need to debrand for using other carriers with your phone. Only a sim unlock might be needed if the carrier branding contains a sim lock.
If you really use one of the unbranded firmwares then the M9 isn't capable of using VoLTE. That's why all the Jio customers from India convert their phones to either the AT&T or the T-Mobile US version.
Like @lucyr03 explained, it doesn't matter which carrier you use as long as the firmware of your phone is capable of VoLTE.

Mine has htc_001 from factory so it is wwe. It was never branded and I get volte on 02 or ee depending on which sim I use.
To unbrand your phone you must flash either wwe euro or wwe usa firmware. All other firmwares are branded.
I was referring to this part of your last post:

And there are more unbranded firmwares than the dev edition and the European unbranded one (which both aren't called wwe since that's an abbreviation for world wide English).

can OTA Oreo update be transferred from 1 SIM card to another

I have purchased my Honor Pro 8 in India while traveling here. It is an unlocked phone with an Indian monthly cash card from Vodaphone.
There is an OTA Orep update available here in India now for this Indian SIM card, BUT... if I would install the Oreo update here in Indian on the Indian SIM, will it continue to work in my native SIM card I use regularly in Sweden; also a monthly cash card, unlocked
I worry that it could disable or BRICK my phone making it useless.
Is the Oreo update Indian specific for Indian SIMs, or can it work when I return home and put in my Swedish SIM.
...AND...if not..when is the projected roll out for that Oreo update for Sweden ?
Thanks for your help

Hi there,
I am no expert by any means. But I will try to answer.
Your question seems to have a flaw in itself. You bought the H8Pro in India which means the device is tuned for Indian networks, no doubt. Will it work in Sweden? It must work, because it seems to support all global network bands.
Regarding Oreo update, if you thought that Nougat would work in Sweden, why not Oreo? And Oreo is not tied to any sim. It is specific to the device and not the networks. So you can go ahead and update to Oreo and enjoy its features. Bests.

Thanks for your reply...so you are saying it SHOULD work regardless of whatever SIM card is used; even if it will be from another country soon...I just don't want to update it here only to find out that for some reason it won't work in Sweden, and in fact, could shut my phone down....you're absolutely sure about this ??
The only reason your phone wouldn't work at home is if the phone isn't compatible with the network bands in Sweden. Your phone cannot be bricked or disabled by the software. Hell, I am running Chinese firmware on my phone and I live in Canada. This phone isn't even sold here!

Stock firmware for Android 10 compatible with Verizon network?

Hello, I'm new to this so I apologize if this is a stupid question.
I'm trying to install Evolution X on my G7 ThinQ, but in order to do so I need to have stock Android 10 installed beforehand. The phone model is LM-G710VM (the Verizon model) for which the latest stock firmware is only Android 9, so I'm trying to find a G7 firmware I can crossflash that has Android 10, but so far the couple I've tried haven't been able to connect to the Verizon network. Does any such firmware exist, or will only Verizon firmware work on their network?
Thank you
After poking around in settings I was able to get my network connection working. In case anyone else runs into this, I fixed it by going to settings>network & internet>mobile networks>network operators>search networks and choosing Verizon. Also, the problem only happened when using firmwares coded for other regions.
