Here's my situation. I purchased a factory unlocked M8 from Amazon (m8_ul_ca, 0P6B12000, BS_US001). I then unlocked the bootloader, made it s/off & SuperCID. I updated the firmware to 2.22.401.5 and flashed ARHD 11.
Everything was great except my LTE speeds (AT&T) truly sucked, getting no more than HSPA+ even though my area has strong LTE. I tried many different radios, other ROMs, even the Dev firmware. Nothing helped.
Finally, I decided to try the latest AT&T RUU with the 2.23.502.3 firmware. This worked. I'm now getting true LTE speeds (10x faster). I'm also now on a different APN ("nxtgenphone" instead of "phone"). At first I thought this was the sole reason, but I changed back to "phone" and was still getting LTE speeds (albeit slower) on AT&T firmware/ROM.
So, here's my question: is this change in speed due to the radio in the 2.23.x firmware, which is different than the ones I had been trying, or something else, either in the AT&T firmware or ROM?
Sorry for the long-winded post. I'm just trying to get this all sorted in my head. ?

Found a "deal" on a SGSII branded from Bell - I live in the south US and want to know if I throw a ROM (say Cog or a US dev. ROM) or even if I odin back to a factory ROM from an AT&T model - will this work? I cant think of something that would cause this to be an issue & I'm pretty sure it would get rid of the Bell boot up screens or any other branding but I am not 100% on that as I have never taken a out of country phone and attempted to do this before. I'm no noob with flashing but I'm also no developer either so your experience & assistance is appreciated!
(I searched & couldn't find this answered)
You don't need to replace the ROM. If the Bell phone is sim-locked, you'll need the unlock code; there's an unlocker program in one of the other forums that works with the earlier ROMs. IIRC, more recent ROMs have a different unlock mechanism that hasn't been reverse-engineered yet.
You can't replace the Bell ROM with an AT&T one, since AT&T doesn't have one -- no US carrier has released the SGS2 yet. The factory ROM will do the job; I bought a EU SGS2 back in May and have used it on AT&T since then. I get 3G & HSPA+ data at speeds up to 7 Mbps, using an old 3G SIM I've had for several years.
Alright so ill start this of by saying, Picked up my note today and loving it so far. Got it rooted thanks to Da G and getting ready to get into roms.
Anyway im making this thread to see if anyone else has tried anything out on the non-AT&T notes(i.e I717M and what not). So far from what i have read people are developing mostly for the AT&T model and saying its not for bell rogers or telus. Now I have been in the samsung world for a while and when it comes to my galaxy there was always ways around this.
For instance most of my ROMs were made for the international version not my bell version. But as long as I kept a copy of the bell modem on my phone i could just flash that and the ROM worked great. So does anyone have a copy of the bell telus or rogers modem for the note? or know if there all the same?
Another example in the galaxy s world was the captivate(Same soft keys as our phones). A person with a captivate could flash an international ROM as long they made a soft key fix when they developed the ROM.
One of the main reasons I ask all of this is because i see so many N7000 ROMs up and running and am wondering what will and wont work.
Look forward to hearing from you all

Bell note here. Been. The at & t roms with no problem.
The only issue that I have is the Yellow Pages crap that appears in my contact list as well as at& t bloat depending on the rom. Easy enough to deal with though.
Aside from that, it's been perfect.
Currently on Team Perfection 4.0.4.

I forgot to add that I haven't had any issues with data speeds at all.
Also, Don't venture into the N7000 roms because they will not work.

The N7000 ROMs can hard brick your phone since the hardware if the two models are completely different. AS Far as ROMs go, most are based off the AT&T software simply because that's the only ICS leak we have available. But you can use any ROM for the i717 on your Bell Note. I have a Bell Note and flashed almost every ROM and never ran into any problems. Also, Ruth the help ofa lot of people on this sure, I've made stock images of the Bell, Telus, and Rogers Notes so we can always go back. Best if luck and don't hesitate to ask anything.
Thanks for the info, I get mine today and was wondering the same thing.
Yesterday I flashed my Rogers Branded Galaxy i717 with Bell Rom and Kernel and have not 1 issue. I chose to flash the rogers i717 with Bell because I use bell mobiletv and this was the only way to get this particular app to work. Again not 1 issue with data or anything else.
No Rooted device either. Just flashed using ODIN.
I'm currently running the UCLE2 Rom on my Rogers i717. I've noticed that I am not getting LTE where I should be. And GPS connectivity is shoddy at best.
I have a second i717 which is stock that is with me to compare (family member).
I am going to flash the Rogers modem to hopefully correct atleast the LTE issue. Anyone know if this would improve my GPS connectivity as well?
For a number of years I have been buying Canadian phones to use on ATT. Canadain ROMs have less restrictions than ATT. For instance tethering and NFC are not locked. Also after rooting my Roger's Note it took under a minute to remove the Rogers branding. (all except splash screen) I was left with a fully optioned unbranded ROM.
I did want to try the stock UCLE2 ROM out of curiosity but I thought it would not install because my phone was not an ATT I717. How did you install it eugenekim618? Personally I would rather wait for the Rogers ICS version. Keep checking everyday to see if it is available.
I have tried quite of a few of the ROMS on here with my Bell i717M, no problems at all so far, other than the "android.phone has stopped working" at startup, I don't know the cause but it only happens at boot.
DO NOT use N7000 roms! But all of the AT&T stuff has worked great for me.

I followed the posts in the Dev section to Root the phone.
Then installed CWM.
The picked a ROM I thought was good and followed the instructions in it's respective post to install.
I've done a lot of ROM installs for the Dell Streak I used to have and for a Sony Xperia X10.
So I am not totally unfamiliar with the process. Just a matter of getting used to the delivery method for each manufacturer. And then, dealing with the quirks of a ROM that is not 100% for your carrier. Goes with the territory, right?
I tried to read all the posts in a given thread as much as I can.
So you are saying you didn't install the one click odin stock UCLE2 ROM?

No, that doesn't work for non AT&T phones I believe. I tried it, and ODIN recognized the COM, but failed to install. From my readings, can't do the one click install on Rogers since it's not a Rogers ROM.
all custom roms should work no problem, ive flashed tons on my unlocked bell note.
its the stock odin files when you want to make sure you get the proper device.
Hey guys Ive flashed pretty much all the roms I can and some I cant lol. So far my experiances have encountered a few setbacks but nothing substantial and allot if not most of the bugs and glitchs occurring in the first & second gen of roms have been fixed or patched.
As far as roms go as was already mentioned as long as you stay away from n7000 model roms and stick to i727 youll be ok. With at&t roms I always seem to have signal and gps issues. Generally tho I find my signal problem will clear itself up on its own and I believe is actually just just caused by the fresh software 'settling in', even though my signal appears low or fluctuating speed testing always shows Im getting peak d/l & u/l speeds. If the signal doesnt seem to improve flashing the Bell stock modem via cwm always does the trick. Gps usually works great, very fast & accurate, when Im having location issues I use the 'faster fix' app from the market, I dont know about anyone elses experiance but allot of the times theres a problem the gps server isnt set to the normal 'north america pool' but servers Ive never seen before or set to an 'international pool'.
All in all besides signal headaches the only other recurring problems are the inherent and unpredictable random force closing of system apps. It can be pretty random but I find a few constant trouble makers to be at&t software update, android phone. At&t update can be disabled easily under applications in the main settings or I was able to actually remove it using 'rom toolbox's app manager but strangely not with root toolboxs remove system apps. For pretty much all other f/c problems the remedy is a running of 'fix permissions', there are a bunch of ways/apps to do it and Ive found using 'rom manager' works the best meanwhile rebooting into recovery and fixing permissions from there will actually cause more problems.
Ok so those are the most recurring and annoying issues Ive had to name a few but the list is too big to write merely because Ive tried just about every rom right from the sketchiest unstable first releases and everything in between lol so feel free to drop me line if your stuck on a problem cause I might be able to help.
But before I end this novel here lol I just flashed the new 'OnlyOne Beta2' rom from the development section and it runs great. The rom is super stable, very fast and features both fully functional S Voice app and fully functional S Notes app. If you havnt tried S Notes yet its awesome the new functions and abilities totally blew me away so I highly recommend you give this rom a try!

If you had LTE before and lost it through flashing a custom ROM or whatever then try changing your APN to your Carrier LTE network. If you never had LTE when you bought your phone, probably the seller gave you a wrong sim. tell her to give you a 403 LTE capable sim, the 401 is only 4G.

Thanks for the tip. But I got everything running again. I did have LTE to start, and have a LTE sim card. The *#2263* certainly helped. And Flapjaxxx's GPS tools in his ROM helped me get the GPS back up to par.

ok now I just lost my LTE after flashing new ROM from Seraphim Stratosphere. How did you get it back. I factory wipe everything and flash Rogers modem and it doesn't work. How did you manage to get LTE back? btw I have a Canadian Note with Rogers. the Saurom ROM was canadian and I had LTE too.

Try *#2263#
Then force select LTE, and select ALL. That should force the LTE connection. So watch the connection bars. You should see a loss of connection, then reconnect on LTE. Once that is established, do the code again, and just select automatic.

When I try dialing it, it says error can't find USSP or something like that... What does this mean?
Just to be clear that im doing the right thing. I go to the dialer and punch the code *#2263#. How do I "force select LTE"? will something popup for me to select it or should I go to settings/ wireless and networks... I don't have those options in "wireless settings", I only have APN settings...
Hi,
I am using CM 10.1 M3. I haven't updated my modem in a long time. It is I717UCLF6. Is that the right one? How do I know which one to use?

It's kinda hard to answer which modem you need without some more details. It's also a personal preference based on where you live. Some modems/radios work better in certain areas than others. What network are you on, AT&T? I'm on AT&T and heard the latest modem for our i717 is the i717UCMB4. You can flash that one in recovery. I used it and it works but for some reason the i717UCLD3 modem is working better for me. I got that modem when I used odin to install this rom, then flashing my favorite rom on top of it. Some people say the UCLF6 modem works better for them. You can get that one here and flash thru your recovery. Sorry I can't find the i717UCLD3 flashable zip. Maybe someone else has a link so you can flash between all 3 and see what works out best for ya.
No need to do any modem flashing. LF6 is the latest and greatest modem available.
Updating.....AT&T released 4.1.2 and a new baseband/modem which can be found here http://forum.xda-developers.com/showthread.php?t=2261713 and is flashable from custom recovery.
I'm testing out a possible switch to T-Mobile. Had AT&T unlock my phone today and got a prepaid T-Mobile SIM in it. I'm getting H+ (LTE?) speeds while doing data transfer and then it drops back to 3G when data isn't being used heavily. I'm on UCLF6. Although I've had this phone for a year, installed tons of ROMs, compiled my own kernel, etc. I'm a noob when it comes to modems and have just used whatever worked. What's the advantage of using a "T-Mobile" modem if UCLF6 seems to be working on T-Mobile anyways? Do you get more speed out of it?
I don't want to lose AT&T compatibility yet as I just got the prepaid T-Mo to test out (been getting crappy reception with AT&T at work and tired of the expensive plan of minutes I don't use). If T-Mo improves my speeds at work I'll probably just pay to cancel my AT&T contract and transfer my number, but for now I'm just testing.
Well I am not sure about the baseband/modem issues on T-Mobile but most important would be the GSM Bands/LTE are compatible. As some AT&T phones don't support 3G/LTE frequencys T-Mobile use. If you are using a prepaid SIM it may not even support LTE for example Straight Talk on AT&T supposedly will only use HSPA+ .
Every time I flash a custom ROM based on 4.16.X firmware I either lose LTE (though HSPA+ still works perfectly) or the ability to receive calls. I've tried ARHD, SD, the Stock WWE, and the US DEV edition, and all of them have exactly one of those issues (it's never both). I'm currently back on ATT stock 4.4.4 ROM (3.42.502.1 firmware), rooted, S-Off.
I thought flashing the WWE RUU before flashing a ROM like ARHD would be enough to upgrade the firmware, but maybe I'm missing something.

WWE RUU indeed updates the firmware, however to the WWE radio and other firmware.
I think a couple things are going on here (assuming your are on AT&T's network):
1) A number of folks have reported call issues while on AT&T's LTE network and running WWE based custom ROMs. The suspicion is that the changes being made by AT&T in advance of HD Voice (Voice over LTE) deployment is not playing well with Euro based ROMs. AFAIK, there doesn't seem to be a fix for this, although I think some devs like Team Viper are looking into it.
2) US Dev Edition is intended to be used on AT&T's network. However, its not clear from your description, but it seems you are using the WWE firmware (radio probably most importantly) with the Dev Ed ROM. If you haven't already, try the Dev Edition firmware with the Dev Ed ROM; either by RUU or flashing the firmware separately. That is the configuration I was running until just last week (giving Sense 7 a try) and seemed to have no issues on AT&T, including travel to a couple different locations around the country.

If you don't mind wiping the phone (backup any personal data that you want to keep before RUU, obviously), then yes that is probably the easiest way to do it.

I just did; LTE is working, but I can't receive calls. When someone calls me, it goes directly to voice mail without ringing
EDIT:
So I actually got a call to come through. When it did, LTE went away and wouldn't comeback, so it definitely seems like an issue of VoLTE compatibility, even on the Dev Edition ROM for me.

Weird. I wouldn't think that you would have the issue on Dev Edition ROM, running Dev Edition firmware.
Can you confirm the RUU properly installed the Dev Ed radio, by stating your radio number?
Forgot to mention that turning off LTE is a workaround. But obviously less than ideal.

I confirm that is the correct US Dev Edition radio baseband.
Weird, I've used mine (as mentioned) not only in my home area of Boston (and surrounding areas) but also while travelling to North Texas, and Washington State, and didn't see any issues. But that is by no means exhaustive. We really have little way of knowing what changes AT&T is making to their LTE network and where (in preparation for HD Voice).
You might fall back to the AT&T 4.4.4 ROM (and even the corresponding radio) to see what will happen. But that's of course kind of disappointing to fall back to KitKat from Lollipop.
You can even try the WWE firmware (4.16.401) zip. But I'd be very surprised if you get a better result on the WWE radio versus the Dev Edition.
Recently ended up with this phone, wanted to use it on straight talk with a AT&T sim since it is unlocked.
It works, kind of.
I get one bar or no signal in places I have 2 or 3 bars on my old HTC one M8.
I thought about trying a different rom or a different radio if you can flash those on this phone. I am used to the unlocked bootloader on M8.
I even tried the aluminum foil mod around the battery I found on these fourms. Currently I am back on the HTC because this thing gets no service. Any advice would be appreciated.
Thanks,

Search the General and Q&A sections for unlocking radio bands, although I don't personally have experience with this - have just seen the multiple threads.
I finally managed to get into the Verizon hidden menu and enable all supported bands, 2 and 5 were unselectable but I think AT&T uses 4. Still getting spotty service, anyone know if any modems are better for gsm than whatever version is with the stock 6.0.1 rom? I've seen a few post mentioning 12b, is that the most stable or something?
How did you did that? Interested in getting 2600Mhz (if possible)
