hii, i am using Lee droid rom 7.4.2 with elemental kernel 4.xx for 2 months and all is working fine but recently i have changed my network to Zong Telecom here in Pakistan which is a subsidiary to china mobile telecom and i purchased its 4g LTE enabled sim card and yes i am in coverage area as well but when i go into settings and select 2g/3g/4g auto i do not get 4g signals and it stays to only H. it means my phone is not getting 4g signal while 3g is working fine... so i went to dialer and entered *#*#4636#*#* and in phone info i changed it to LTE only manually. and after few seconds all network dropped and i am getting zero signal..... i am afraid that this problem is due to my custom rom or custom kernel because i am getting 4g signals in my galaxy s5 .... so any idea what to do please?? any fix?????
Note: Zong telecom uses LTE FDD band 3 @ 1800 Mhz which our M8 supports... so no problem here as well.

Specific band support depends on what variant (CID). Are you saying that you know your CID variant supports LTE Band 3? Otherwise, it may not.
Check your APN. Carriers sometimes use a different APN for LTE.
Have you tried the SIM in another phone to verify LTE works on that phone?

APN settings are automatically provided by network when we insert sim and restart phone.. 3g is working fine and secondly i dont know about that CID thing i m using lee droid rom which is based on 4.16 european rom i think so, can you please help me out of this??

CID or Carrier ID is the carrier or region version of the phone. It has nothing to do with the ROM, and can only be changed with s-off.
To determine your CID, do adb getvar all. Don't post your IMEI or serial number, if you post the getvar output.
You can also try a CID app, but I think these sometimes are wrong; and adb getvar all is the most accurate way.

That version should support LTE Band 3. I would try the SIM in another phone, and see if that phone gets LTE. Could be a problem with the SIM or the account.

Hi guys,
I'm having a problem with my phone for a while already.
I have HTC One M8 of T-Mobile.
I'm currently living in Israel, and I bought it here locally from some private mobile store, back then I didn't really realized the difference
between International to all other like T-Mobile, AT&T and such.
After I moved to my current ISP, I'm having trouble with low reception in some places while other phones with my SIM card are working fine and getting good reception.
I understood it's happening because of the modem the T-Mobile are using, it's using other frequencies that aren't available here, only in US and such.
So, is there a way to flash or something a new modem? Or is it something that is hardware based?
Thanks in advance! :good:
Band compatibility is software based on this phone (unlike most previous smartphones).
S-off by sunshine ($25 US) and than you can flash another carrier versions firmware to change the band compatibility. You'll need to determine what bands your carrier uses for 3G and 4G (LTE) and see what carrier version's firmware will work for you. But the Euro international firmware (401) may be a good place to start.

But in the future you should research properly before buying a phone from a source other than your carrier. You're lucky this is fixable in software this time.

Hi, Thanks for the answer.
Well, I'm already S-OFF.
Now I'm using T-Mobile official ROM. But before that I was using Android Revolution HD based on International firmware (401), and I had those problems, too.
Because I experienced those problems with the 401 firmware, I tried and installed back the official T-Mobile ROM, to find out that I'm still ****ed up -_-
If it helps, my ISP is currently working on those frequencies:
3G: 900Mhz, 1800Mhz
4G/LTE: 1800Mhz
My previous ISP was working with 850Mhz instead of 900Mhz, and it was working just fine. It's because my current phone doesn't support this frequency.
I'm surely learned in the hard way that next time, I'll but only international releases.
Another question... If I'm using T-Mobile official ROM. When I'm flashing another firmware, will I have to re-install another ROM?
Edit:
I flashed the 4.16.401.10 firmware, while staying on the T-Mobile official ROM,
when finished flashing the ROM, I went to the About section -> Software Information
And I still see that the previous firmware version (4.20.531.4) is used.
I tried to re-flash again the firmware, but still the same.
It's just due to the ROM, ignore the software information in the offical ROM or well baseband.
If you'll go to HBOOT you'll have 4.16.
Also I feel your pain, while I am using partner myself, I can't get 4G despite changing the NV values although you suffer from another problem, sort of at least, I get perfect HSPA+ but I have no 4g lol. I am using the Verizon model though. You don't have either perfect HSPA nor 4G do you? T-Mobile is 2-4-12 with thier LTE bands.
You could change the NV memory to support 900 WCDMA and 1800 LTE but I doubt it would work.
Try flashing another ROM with the euro firmware. Also Redpoint73 can't he just change the MID and convert to a generic Euro device?

Thanks for the reply.
Yesterday I flashed a new ROM (ViperOneM8) with the 4.16.401.10 firmware, but still the same issue, no real LTE. I'm getting 3G speed (7-10Mbps DL / 2-3Mbps UL).
So I'm guessing it won't resolve my 2G issues either in some places, like in my current place of work.
BTW, what are those NV values you've mentioned above? How it can be changed?

Tried to do that, but no luck. Actually when I'm writing the new values, I think it's not saved. Because when I'm pressing 'READ' again, it shows me the previous values.
Maybe it's because that I didn't go into CDMA mode? Because if so, I have no idea how do I enable this mode. Couldn't find anything.
Thanks.

Ignore the CDMA mode, it doesn't apply to you, odd, it should save just fine as long as you got the right drivers in your "Device Manager", and since you can perfectly read the values, it should mean that your drivers are fine. And it would be grayed out if you wouldn't put that terminal command so no issues there either.
Your ADB and other usb settings are enabled right?

Yeah, I can see the HTC diagnostics interface in the device manager, after I put the command you gave me in the Terminal, and still.
Anyway, you said that you did that, too, and it didn't even help, correct?
I guess I need to wait at least another year till I buy a new phone
And unfortunately I cannot move to another ISP like Pelephone or Golan Telecom which will work fine I guess , because my current number is my work number.

This is normal, and as it should be. Software number in Settings only tells you the number of the ROM, not the firmware.
To determine current firmware, look at OS number on the bootloader screen, or do fastboot getvar all, and look under main version.
Alternately, if you look at the radio baseband number in Settings, it should have changed to the "Euro" radio. Although, you would need to know the radio number that corresponds to the 401 firmware.

Not very knowledgeable with these NV values. But I've seen multiple reports of changes not sticking on the "GSM" M8; and haven't seen a single report of it being successful (on GSM version). I suspect these are only changeable on the "CDMA" (Verizon, Sprint) M8, and its locked out on GSM versions.
I suggest sticking to trying radios/firmware or other solutions.

Just because the speeds are less than you expect; does not necessarily mean you are not getting 4G. Your network can have congestion, poor reception at your specific location, or other issues. I've gotten anywhere from 3 Mbps to 30+ Mbps DL on LTE with good reception, same location.
Do you get the 4G or 3G icon at the top of the screen (status bar)?

What 2G issue? I don't think you've mentioned anything about that. 2G is pretty standardized across countries/regions. At least to the point that band compatibility is usually one of the bands common to all M8 versions: 850, 900, 1800 and 1900 (CDMA networks excepted). If you are having reception issues, changing radios probably won't make a huge difference in 2G; at most probably just minor effects depending on tweaks to the particular radios.

Yes, that certainly helps. And this, and your s-off status (and as many details as possible) should have been included in your top post.
Based on your statement, and the specs on this webpage; the Euro firmware should only get (on your carrier) 3G on 900 Mhz (1800 Mhz missing) and LTE should be okay on 1800 MHz.
On the T-Mob firmware, the specs are missing all the bands used by your carrier for 3G and LTE.
However, it has been reported by some users, that some bands seem to be supported that are not listed in the "official" specs; further confusing the issue. Ideally, you would want to fine a version's firmware that supports the same exact bands that your carrier uses (as you've noted in the quote). While no versions listed in my link satisfy that requirement; there are other versions than those listed.

First of all, in the new ROM I'm not getting anymore the 4G icon. I have experienced it back then when I was using Android Revolution HD,
till I decided to try and install the official RUU of T-Mobile to see it the problem persists. Only then, in the T-Mobile ROM I saw the 4G icon.
Although the funny thing is it was always using 4G icon, no matter what, heheh, so I didn't really trusted it (only when I was getting 2G reception, and the icon changed to 'G').
And yeah, I'm pretty sure I'm not getting 4G, I tried it in few places. My ISP just upgraded their LTE systems and lots of users are now getting very high speeds like: 20-30Mbps DL / 10-30 UL, some even more.
About the 2G reception I can confirm that it's happening only in my device. When I was getting 2G reception, I took out my SIM card and put it in 2 other phones and they got 3G with good signal.
Anyway, my ISP is working with those frequencies for the 3G: 900Mhz, 2100Mhz.
And as much as I understood after reading about it somewhere, the T-Mobile HTC One M8 doesn't have the 900Mhz, only the 850Mhz & 2100Mhz.
Damn, I'm desperate ;(

Change CID and MID to convert to unbranded Euro is possible, yes.
I agree, it might be a good idea to "baseline" the phone to "official" unbranded Euro ROM and firmware. And therefore eliminate the possibility that the custom ROM or T-Mob firmware, etc. are causing any of the network issues. In particular, the US carriers are more restrictive than most (especially Europe) and US radios are therefore probably the worst to try.

You can't go by what the stock T-Mob ROM says (signal icons). T-Mobile calls HSPA+ "4G".
Don't know about T-Mob, but AT&T has different icons, where "4G" icon = HSPA+, and there is a different icon "4G LTE".
Confusing, I know. But blame it on the marketing gimmicks of US carriers.
And the "G" icon is really bad. It means you are on GPRS, which is the worst possible data connection, slower than EDGE (which will show "E" icon).

Hard to help, if you don't give the proper info. Looking at this website, it seems that most carriers in your country use 900,2100 for 3G. If this is correct, and your carrier uses 1800 for LTE, than the Euro firmware is where you should be, as it supports all those 3G (900, 2100) and 4G (1800) bands.
T-Mob firmware will give you the needed 3G bands (900, 2100), but not LTE (1800).

1111111 is SuperCID, which will "pass" all CID checks (although, it may/may not block official OTA updates according to some reports, I'm not clear on this). So your CID is okay to "convert" to the Euro version.

Another "helper" asked me specifically if you can change CID and "fully convert" to the Euro version. "Full conversion" requires the correct CID and MID, and makes the phone a Euro one, as far as software is concerned (including enabling Euro OTA updates).
I'm not saying you need to do this, I was just answering the specific question posed by another.
But I'd at least suggest going to stock Euro firmware and stock ROM (changing MID probably not required to do those) and see if that helps. Stock T-Mob ROM and firmware is certainly not helping, might be hurting.

That baseband probably matches that of the 401 firmware. Since you said you tried 401 and T-Mob firmware (and not any others?). The T-Mob Lollipop baseband is 1.23.2133 blah blah blah
The baseband version will change whenever you flash a firmware. But the build version (in Settings) will change whenever you flash a ROM. They are independent of each other.
BTW, I noticed you are running a really old version of ARHD. This is not doing you any favors, either. I'd recommend the 4.15.401 firmware, and the same base custom or stock ROM, and see if that helps.

BTW, I noticed you are running a really old version of ARHD. This is not doing you any favors, either. I'd recommend the 4.15.401 firmware, and the same base custom or stock ROM, and see if that helps.

How could you notice that I'm running ARHD? Because I'm running ViperOneM8 (4.5.1), based on firmware 4.16.401, which is newer than the one you suggested.
Hello there guys, im wondering if it is possible to unlock a band from my htc one m8 from at&t, i live in venezuela and my current company (Digitel) the 3g band is 900, but this phone only have the 3g band on 850, my question is can i unlock this by any chances because is annoying that my phone is from E to 4G and manually i can even recive calls when its 4G and it wont change to 3g
(sorry about my english)
You need s-off by sunshine (if not s-off already). Then you can flash another version's radio/firmware to enable the desired band(s).
May also need to change CID and MID (after s-off) if the firmware is signed.

According to the following specs, Euro or Asia firmware should support 3G 900 MHz: http://www.gsmarena.com/htc_one_(m8)-6074.php
Although, keep in mind you should also verify the LTE (4G) band used by the carrier is also supported by the version's firmware you pick. You didn't state what band your carrier uses for LTE.
Also, it should be kept in mind, anytime you purchase a phone from a 3rd party source (other than your carrier) you need to do the proper research to verify the device actually supports your carrier's network. You're lucky this time (if you get the proper bands working). This is the first smartphone chipset that allows band support to be changed in software. On previous smartphones (and may also be true on other current smartphones using other chipsets), band support was set in hardware, meaning there is no way to change it.

thanks, my carrier uses band 3 (1800MHz) for LTE and for 3g uses band 8 (900MHz) so what firmware do you recommend?

Same as I've already stated, EMEA (Euro) or Asia supports both those bands.
EMEA is a very common (probably most common) version on this forum, so that may be your best bet as far as ease of getting the files, fellow user support, etc.

NO. The Developer version is US, not Euro or Asia. Why do you think the Dev Edition has the bands you want, or corresponds to the Euro or Asia versions?
The Dev Edition has the exact same band support as the AT&T version, so this is the exact opposite of what you want (doesn't have the bands you want).
Euro firmware is probably what I would recommend (as previously stated), and can be found on the following threads (as well as other places):

Follow the instructions as applicable, for changing CID and MID (after s-off).

Try the SIM in another phone, if possible, to see if it works on 3G on another device.
Also, be sure the APN info for your carrier is properly entered. Double check and triple check every input to make sure every single character is correct. Even a single added space or missing character can prevent you from getting data properly.

How does the APN on the HTC compare to that on the Nexus? Are they identical?
