I have NFSFAN Latest rom with GPS, I want to go back to the original bell rom because bell world said they can't change my cell phone number with the custom rom.
Thanks
I have done it so many times......nothing hard nor dangerous.
Just use the latest bell firmware (with the GPS) and flash it.....

Hmm sounds kinda weird, I don't see why the need the stock bell ROM to change your number. Just re flash it with the bell ROM, go get it changed, then flash your custom ROM back. Just don't try to return your phone until you have downgraded the bootloader and flashed the stock bell ROM, but in your situation it does not sound like there is a need to downgrade.
just make sure that the Official Bell Rom has the 3.xx Radio or more,, and you will be fine.
Well I flashed to NFSFAN's ROM hand had nothing but trouble after that. Now, to be honest I couldn't say if it was the ROM or the flashing that caused the problem, as I unlocked as I was supposed to first, but I could not reflash back to OEM after that using active sync, I had to do it from the storage card. And now after trying it yet once again, my phone shows No Service...
So I would say that your mileage may definitely vary... I'd say if you're able to downgrade to the Bell 3.09.666 ROM from activesync you should be fine.
Keep us posted!
My radio initially is the original official radio, but then I want to upgrade to it 1.17.25.09.
Then I read some post saying that I should downgrade it to 1.02.xxxx or below, then I can unlock the security lock.
However, I think I misunderstand it and just downgrade it by flashing the radio, I think I am supposed to flash a rom which has an old radio with it.
But lucky that time I was able to upgrade it without security unlock my phone.
Now I just flash the radio 1.17.25.09 straight away, and now my radio is 1.17.25.09.
However, there is a little problem now.
I wasn't able to connect to the wifi internet I usually connect to, is it the problem of the radio? or is the problem of the ROM? Can I do some test to ensure my wifi function is correctly working?
Just one more question, what does the flashing a new ROM affect/change the performance of the phone?
Many thanks for reading this long thread, hope I can get some answers
I think the wifi Problem is a Problem of the rom, because 2 years ago i put a new rom on my htc wizard and then i was no longer able to connect to my home network.
Hope i was able to help a bit!
Thank you for your reply, I will try to flash a new room tonight and see whether it is functioning
Assuming that most users use their phone in the region they bought it why would you flash a another one, since the original was probably optimized for their region. Will flashing all these various ROMs also change my radio? Also...is radio the baseband?

Depending on where and when you got your phone could mean a newer, faster radio might have come out. I do believe radios are area specific, but not sure.
I think any radio for the t989 will work but your data speeds, call clarity or even phone performance might take a hit.
Usually roms wont erase or put another radio on and if they do you can always just flash the proper radio.
Generally going from rom to rom while doing a full wipe will not remove your installed radio. And yes the baseband is your radio version.
Hope this helps, I only have a basic understanding and usually try to stick to the radio my provider pre-loaded.
For some reason, every time I try to install a sense based rom, it never boots.
I'm fairly new to flashing, and have flashed 4 or 5 aosp roms. Every time I install one of those, it always works correctly, no issues.
I have tried to flash several Sense based roms, such as ARHD 20.1, Insert Coin, and nv, and each time, it never works. I always do a factory wipe beforehand as well as a wipe in the aroma installer. It will go thru the process and install, and then prompt me to reboot, which it does. Once the screen comes back onm however, it just hangs on the white htc screen with the red development text. When i get back to the hboot, itll show nothing for os.
I thought the issue may be that i dont have the latest firmware, but even people that dont have the latest firmware still are able to boot into the rom. Also, I just tried the NV rom which is based off my firmware, and it still gives me the same trouble. Does anyone know what I'm doing wrong?
I'm running an ATT Htc One m8, rooted, unlocked, s-off with sunshine, twrp recovery

Give the ROMs about 10 minutes, and I bet they will boot. The extremely long boot time, and lack of boot animation (another symptom of this issue) makes a lot of folks believe the phone is stuck/frozen, when in fact its just taking a reeeeeally long time to boot.
If its true that the ROMs in fact never boot, it might just be an issue with your recovery. fastboot erase cache and either re-install recovery, update to the latest version, or try another recovery (Philz).
Even if the Sense ROMs boot, you might find some serious things are broken with your outdated firmware, such a broken WiFi. So I suggest either update your firmware or stick or ROMs based on your present firmware.
Ok thanks, i will try again. Ive read a bunch of threads about updating my firmware but couldnt find an answer to a question I have about it.
If I upgrade my firmware to the latest WWE 3.28.401.6, will it mess up my ATT settings like the bands? Also, will it erase my internal sd card?

Firmware includes the radio baseband, so it may cause issues with reception on AT&T. It seems at least a couple folks have been flashing the 3.28 firmware, but I haven't seen enough reports to give me a warm and cozy feeling. With S-off (which is required to flash the firmware, anyway) you can always revert. But still, basic reception is more important to me than a couple updated features. Personally, I'll probably wait until the 3.x firmware specific to AT&T starts rolling out.
It seems like the M8 is radio agnostic like the Nexus 5 based on my experience.
I am on Rogers and flashed the latest firmware and my LTE works no issues.
The latest firmware is supposed to be EU so technically those North American bands are not supported but it works no issue.
Leads me to believe that the radio does not matter like the N5 where the 820 and 821 radios were interchangeable.

Thanks redpoint, you were right, I gave it some time and it did come on. You always seem to be the one answering my questions, I appreciate it.
As for the new fw, I was thinking that would happen too from what I've read, I just needed someone more experienced to confirm that. I think I'll wait as well.
Thanks again

On the 2.x firmware, some folks in North America (I can speak mostly of AT&T specifically, although there are a lot of network similarities with Rogers) had varying degrees of issues with the "international" firmware. For some, the reception was worse, and others had NO SIGNAL whatsoever. Probably depended on what bands AT&T was using in their specific market.
Can't say whether 3.x firmware is the same way. But in my experience (or at least, reading reports by others here), I would have to disagree this phone is in any way "radio agnostic", at least from a software perspective (as the hardware is common among at least GSM versions, and baseband software is the only difference - but that is a slightly different topic).
So what is the latest firmware I can flash that's been known to work? I've seen that viper one is based off the 2.xx fw so do you know of anyone who's flashed it with att variant without any problems?

For the record, I have an AT&T model and am using the 3.xxx.xxx.6 firmware with absolutely Zero issues as far as signal. I get the exact same reception I did stock, and Very, Very similar reception to what my old Optimus G did in the same locations.
This indicates that there must be either a difference in hardware revisions (related to how some M8's can be firewater'd, whereas others need Sunshine), Or, the int'l radio firmware may not support the bands that are used on some towers in some locations. I'm leaning toward the former. For the record, my M8 is a "whelp", and I had to pay for Sunshine.

My guess would be the former as well. Keep mind that AT&T uses five different bands for LTE depending on your market region. Also keep in mind that travelling to another location may result in losing LTE reception (when you otherwise would have LTE on a AT&T specific radio).
Although none of this explains why I've seen some folks get NO SIGNAL whatsoever on AT&T's network after flashing the international firmware (2.x version, haven't seen any complaint yet on 3.28). Even if no LTE, those folks still should have been able to get HSPA and/or GSM since those AT&T bands appear to be supported by EMEA specs. So it leads me to believe there is something else going on aside from just band compatibility. Such as the network not falling back properly to HSPA/GSM.
I certainly don't have an issue if folks want to experiment with the 3.28 firmware on the AT&T network (as long as you know what you are doing, and are aware of the possible issues). Its certainly tempting with the 3.x based custom ROMs coming out. I might even experiment myself if I free up some time. But that spare time is a bit of a premium for me right now; and I also can't really afford ATM to have the possibility of reception issues or no service.
I was able to successfully upgrade my firmware to the 2.xxx by using skull dreams' method. As soon as my rom loaded, however, WiFi and data weren't working. I read through the thread and found that clearing cache and dalvik would fix it, so that's what I did and it worked. (initially I tried to wipe both at the same time, but it gave me errors; further reading showed I needed to wipe cache first and then dalvik).
I would now like to upgrade to the 3.xxx fw so I can install arhd 20.3, but want to know, if I upgrade my fw and it messes up, can I just do the same renaming and putting it on ext SD card to downgrade back to the 2.xx fw?

You could always restore the backup you should be making before you do any mods on your phone. That would be the safest way.
So if I upgrade my fw then restore a backup, I will lose my fw changes?
I make nandroid backups before I do any, so I have approximately 60gb of backups on an external HD, and I always keep 1 or 2 on my internal and external storage
Is there a way just to flash the Verizon radio only to a unlocked 6 pro and not have any issues on custom roms. I am currently on a custom rom and I flashed a non Verizon July ota update, but I have a Verizon sim in it now and something's not right with the cell/data service
Thanks !
It would be best asking in the ROM thread for that particular custom ROM, in my opinion. If the custom ROM already just uses the stock radio image as is without problems, then yes, you should definitely be able to just flash whatever stock radio image you want, to experiment, but there might be details I wouldn't know without being more knowledgeable about the custom ROM itself.
If you can flash it, you can Google it but it's probably something like fastboot flash radio <radio.img>. Replace <radio.img> with the filename of the radio image file that you have in the same folder as your ADB/Fastboot commands, or however you prefer to do it.
Good luck!

Yeah I know the commands from past experiences but rooting and unlocking has changed since I last rooted. Because of the different partition set up it changes things. I was used to having cwm recovery or twrp but it seems most phones now a days need to be fastboot flashed and not really having a custom recovery to flash things. Anyways I appreciate the feedback.
I will try just flashing the radio.img unless someone tells me it's won't work like it used to
I'd take a look at this thread:
Thread 'Verizon calling problems' https://forum.xda-developers.com/t/verizon-calling-problems.4460389/
I'm using the current VZW firmware (I'm on prepaid VZW) but flashed A13's beta 4.1 radio because it seems to work better for me in my locale. Do I have objective data to back it up?
Nope.

I'm willing to bet most of the radios for American based stock ROMs are the same. I think vendor and various system things are what is changed between carriers because they're all designed to run all the same bands.
