Develop Bugs

[Q] More Dev support, GSM or LTE version?

I'm sure a lot development will be cross compatible but as I've seen and experienced on multiple other phones, including the NS and N1, there are certain things that are unique to particular models aside from the radio. Any speculation as to which version of the GN will likely receive the most support?
I don't know the ratio of US based developers vs European developers generally is but it would seem that with Verizon being the only officially named carrier at this point in the US that most devs here will be working on that version while other areas that will have GSM launches will see dev work in that direction. I'm hoping the GSM version gets a quick carrier release in the US or at least a proper domestic retailer (importing is both expensive and warranty is either a hassle or strictly unsupported).
Just wondering if there are any opinions on this, especially from developers.

It will end up on every carrier eventually.

There will most definitely be more support for the GSM version, as it will be sold in the USA and the rest of the world. The LTE version will only be sold on Verizon in the USA.
If the G2/Desire Z combination is any indication, having thousands more people outside the US with almost the same phone as the T-mobile G2 has brought huge amounts of development to the platform.
But overall, FWIW the phones will be pretty darn similar, and the only difference should be the network stack required for Verizon's LTE network to be added into custom ROMs. There will be plenty of people on VZW with the GN to develop ROMs. It might just take a little extra time because VZW's official updates will no doubt be slower coming out.

What he said

i'm sure the same ROM will work on both model as it's in Nexus S and Nexus S 4G
the DEVelopers just need to include the extra reference/drivers into their kernels and/or ROMs

Or it could simply be an overlay setting when compiling. It's probably not that difficult and any decent roms will be based on source anyway.

I agree. ICS was intended to be platform independent. It'd be a large oversight if developers missed that.

AT&T Note II Cons compared to the International model?

As with just about every AT&T phone now a days it seems stuff is missing or gimped from the international models.
Already it seems like the Note II has only Tri-Band 3G and possibly no FM Radio, I've also heard something in the forums of it only supporting 21mpbs 3G rather than 42?mbps 3G like on the international models... can anyone confirm these things or know of anything else the AT&T Note II is missing? I'm really disappointed with this kind of stuff.

Iirc att doesn't even support 42mbps, that's Tmobiles area. We have LTE, which is better. No FM radio is on all US versions. Blame the FCC

but.... it's not just ATT.
Some people just have weird personal vendettas against some cell companies saying they're "gimping" their phones. There is usually a pretty good reason. Like everyone was freaking over the s3 only getting a dual core in the US but it was because the chipsets didn't support LTE yet. Is that the carriers fault? Nope. Sure ATT wants you to use more data (they aren't a NPO lol) but they aren't the only ones to blame for stuff.

AT&T negatives:
LTE will use more battery power (even if you don't have LTE towers in your area or mess with the APNs - there's currently no known way to disable the LTE chip so it will draw power at least searching for a LTE signal.) For some, the positives of LTE outweigh this concern.
Carrier locked device - can't toss in a tmobile SIM and expect it to work. On the other hand, it's usually possible to SIM unlock the phones if you can talk AT&T into it and/or pay someone for a code.
Carrier controlled firmware updates - AT&T devices are typically 3-6 months (and more in many cases) behind international phones on firmware updates including bug fixes. The only carrier slower than AT&T for firmware updates is Verizon (and they might actually get the SGS3 to JB before AT&T does.) It's quite possible that a serious bug is found on the gnote2 and gets fixed for N7100 users, but AT&T (and other US carrier) users are left having to deal with the bug.
Carrier bloat. (Most of this can be frozen, but there might be parts coupled tightly enough with the rest of the firmware that it's difficult/impossible to properly disable it.) In some cases, a user actually might want some of the carrier bloat, however.
Missing firmware items - This goes further than just the FM Radio. I noticed that on my i9300 (international SGS3) there were many more programs than on my wife's AT&T branded SGS3. For example, dropbox, samsung apps, etc. Some of these are just bloat (so don't matter) and some are significant depending on the user.
Possibly a locked bootloader - this is unlikely, but until the phone is released, it's always possible.
Lack of (or less) support in the developer community. The AT&T phone likely won't get near the level of developer support that the international one gets. Put another way, for every 1 developer with a 317m, there are a dozen with n7100's.
This is only a partial list and is likely missing items that we won't realize until the phone is released. On the other hand, I've purposely included at least one item I doubt will be an issue (bootloader) to make the point that we don't yet have complete info.

Seeing as it's already been successfully rooted, I don't think the bootloader is an issue.

I don't think it'll be an issue either, but the AT&T model hasn't been rooted - the Canadian variant has. Being that the devices will have different pre-loaded bloat, it's also possible they'll have different bootloaders.

This was back in Sept, posted by Briefmobile.. they've been pretty good with their sources.. and per article, the source has been spot on with the info it's been giving out... and it's said to have been rooted and comes with an unlock bootloader..

Serious question, but why would this be the case? Other than the radios, aren't the hardware on all of the US variants and the international Note II pretty much identical? Couldn't we just flash the rom, but keep the modem corresponding to our carrier?
Not a developer or anything, but I'm just a curious consumer that might buy the Note II when it gets released on AT&T

That would be ideal, but it's doubtful. N7100 firmware doesn't work on the N7105 (international LTE), and there have already been kernel-level differences noticed between the 7105 and the tmobile variant. Chances are high that the tmobile variant is closer to the 317 than the 7105.
Of course, it's all guesswork until we start actually messing with the phone.

2 more (slight) cons. Native tethering on ATT is not free. And no FM radio app. Hopefully both can be fixed later by devs.

Lack of FM radio - pretty trivial I think.
Lack of a 32/64gb version of the phone (16gb only). Also trivial considering 64gb cards.
ATT tethering not being free isn't only an ATT issue and it's also not a phone hardware limitation....so I don't see this as a con of the phone itself, rather a carrier con. You can get this via rom

I read where someone mentioned that the AT&T model was missing the multi-window feature. Is it still not on the device? The international Note 2 has it. That's a pretty big omission if it's not there. I've been thinking really hard about which one to get but I'd rather have no bloat, fast(er) updates, and full manufacturer software instead of a carrier crippled device with LTE.

I kind of agree with this (especially since LTE is over a year away here) No FM radio ( I do use it and it saves battery as well as a lot Data)
Deal breaker is ROM development though. I learned my lesson with the Captivate insofar as development I was really hoping the ATT version would be equivalent to the International. Have to wait and see.

I realize that people really want custom ROMs, as I would, but considering how much better the hardware and OS is getting (note 2 cpu + project butter + 2gb ram) is bloat really so much of an issue?
Seems to me that we can always remove some of the apps we don't need.
Now as for customizations, like the "phablet" stuff that Jamie did with the paranoidandroid rom, those I'll miss.
But overall I'm excited to see how well this phone works, I should have mine on the 7th. I'm looking forward to the new S-Pen integration features, which should be really cool I hope. I am also anticipating a very smooth running device even with the bloated ATT rom As to custom rom's we'll have to see how it goes and keep our hopes up.

Pretty sure the i.international models did not have the multi window function on release either (except maybe the Korean version). They got it in an update.

Same with the original Note vs. the international Note. The development was totally different. The development for the AT&T Note didn't even compare to the international. I almost traded my att Note for an international model but I decided to sell it and buy the One X. I forgot to mention in my previous post but that is also a huge consideration. It looks like, as of now, I'll be going with the International Note 2. I use Straight Talk on my One X and plan to with any of my future phones so it's not like I'd be able to use LTE if even my area did have it, which still won't be for at least another year or so.
I wonder tho if the development will be roughly the same since they have the same chipset this time around. Such as roms for the international being portable to the carrier versions and vice versa. Still, even with that, it looks like international versions usually have more development. Plus they get a head start.

Is our Samsung galaxy s3 T999 LTE capable?

I am 100% sure as I have consulted with Samsung internal people and Tmobile managers. The S3 is the SAME device for all carriers in the USA hardware wise. Each Carrier then gets source from google, and samsung modifies it (like adding TouchWiz for example). Then they dispense the devices. So if you believe that much....it would be logical to reason that our T999 can use LTE once ready with android updated to a version similar to the one running stock on Verizon handsets for example, which currently does. Also the point about FCC making some rule against it is wrong. I know for a fact that T-Mobile is deploying LTE in a few test cities now! And over coming months some large cities including NYC, LA, etc will be turned on to LTE. I believe at that point we should get another OTA just like the MD5 example (a new radio and Touchwiz and Android updates) will be pushed and also devs will make rooted versions as Jovy does for us now. Again I am unsure why everyone wants to piss and moan and argue that this is not true. I would think most people such as myself are thrilled I do not have to spend several hundred dollars more at the end of the Fall to upgrade to the S4 since I do not believe that phone has really tons more things I need (13mpx camera I dont care...quad core...slightly larger screen....so on....all minor stuff to me). I like the S3 and wish to use it for a while. So say what you like but I am certain our phone with same Qualcom chipset MSM8960 (review this for proof: http://en.wikipedia.org/wiki/Snapdragon_(system_on_chip) will work on LTE network once it is updated in coming months.
Sincerely,

Out of curiosity, why would T-mobile release an S3 with LTE, while the S4 is already capable of LTE? That just doesn't make sense especially at the fact that they will most likely cost about the same. If this ends up being true, T-mobile makes the dumbest decisions imho.

Lol, I've been with Tmobile for 6 years, nothing they do surprises me. But, the T999L is fact, and on its way. The S4 is more then a S3 with LTE, at least that's what Tmobile is betting on people think.
Edit: I think it came out last month!

Teardowns of the T999 have indicated that the LTE hardware does exist, but remains dormant. The baseband and duplexers can support it, of course. The band 4 power amplifier supports WCDMA and LTE. In fact, so does the band 1, band 2, and band 5 power amplifiers. Also notably, the T999 features a band 12/17 LTE power amplifier with a band 17 duplexer.
The better question is: would flashing the T999L firmware work properly on a T999?

You know what would be ironic? What if the T999L was simply T999's that have had their "dormant" LTE components activated and then resold? That the T999L is the T999 recertifed by the FCC and requiring a new designation but not actually a new phone?
Thus one runs out and purchases the T999L for LTE and has the same phone in hand (with possible solder pad jump or other non-software override for LTE).
That's my tinfoil hat conspiracy for the day. :cyclops:
This would be a closely held secret. Especially if the customer turns in their old phone and it's turned into a T999L for the spares/replacement stock.

But, how does one tell which board rev is in his phone? is there an app?
I don't get the same kind of dashboard details on my (now stock) GS3.
About Device says:
Model: SGH-T999
Android Version 4.3
Baseband version T999UVUENC2
Kernel version 3.0.31-1962493 (Sat Mar 8 2014)
Build Number JSS15JT999UVUENC2
nothing about Board version or Device.
One local TMobile store said it wasn't finding 4G/LTE only because I had rooted it (I since unrooted it and ran all updates).
Another store insisted on the T99l designated models had LTE.

yours is NOT lte enabled. rooted or not doesn't matter.

[Q] Modding the GT-n7105 to get LTE on Tmobile

I was recently gifted a Note 2, which is awesome and I love it, but I feel it's a shame for such a nice phone to be stuck on edge, even with Tmobile's refarming (laaaaaame). Everything I can find on Google says that it's a hardware limitation, not firmware. So I wonder, what if I swapped out the radios?
I'm aware that such a feat would require replacing the entire motherboard. If I buy a T889 motherboard and put it in my phone, what kind of issues would I run into, if any? I would have to flash firmwares and radios and such- would going to the Tmobile Note 2 board and flashing everything stock that I find over there be sufficient? Any IMEI issues that I would run into? Would my phone now be considered a SGH-T889?
No, returning/reselling and buying the T889 isn't an option. It's too much effort for uncertain risks for something I don't care all that much about. I'd be open to a trade, but it would have to be an exact counterpart to my own (unlocked, titanium gray, screen protector from new, great condition). I'm sure trading is much easier, but modding sounds much more fun.
Even if I do the mod, it won't be right away, as motherboards are rather scarce and the prices are higher than I'm willing to pay.
Not sure if it matters, but my note 2 is stock rooted and my efs partition is backed up.

1. research/check on the LTE frequency bands t mobile uses then go check for example at gsmarena.com if the N7105 supports those bands by checking it's technical specifications
2. in the mean time you can try this.. go to SETTINGS then MORE SETTINGS then MOBILE WIRELESS change your NETWORK MODE to LTE/GSM/WCDMA AUTO
if this doesn't work and t mobile runs in an LTE frequency band supported by your handset it could also mean you need to upgrade/replace your SIM card .....same number but the new chip has LTE features inside it..it's possible

I've done my research on this. Tmobile uses AWS, which the n7105 doesn't support. Tmobile is refarming some of their 1900Mhz to free up frequencies for LTE, which the n7105 does support, but I'm not getting 3G speeds in those areas at all. I've seen around these boards that I'm not the only one to do so.

As I said before, my research indicates that it's a radio hardware issue, not firmware. There are posts on how to get AT&T/Verizon/Sprint/Tmobile versions to work on each other's networks, but not much on getting international versions to fully support LTE in the US. Besides, I get 4G just fine in my old G2.
Which brings me to my original question- what issues would I run into should I do a motherboard swap?

Bump.

There are posts on how to get AT&T/Verizon/Sprint/Tmobile versions to work on each other's networks, but not much on getting international versions to fully support LTE in the US. Besides, I get 4G just fine in my old G2.
Which brings me to my original question- what issues would I run into should I do a motherboard swap?

I have seen my note II bring opened up and I have seen a video of a N7100 being open up...they are virtually identical to me atleast.... I saw all the complex/circuitry /smart chips were all on one board like RAM, CPU including the radio...Obb the motherboard..most things if not all which connect to the motherboard are dumb circuits like there was a small board which holds the charging port and Mic and that board has a cable to connect to the main mother board...which I'm pretty sure it's dumb.no advanced circuitry...the 3.5 mm Jack port same thing, the antennas are just cables nothing smart on that, the LCD had a one cable I believed just connecting to the mother board...I personally, only my opinion there could even be a good chance somebody could even switch a note II motherboard and force into a note I so if you want to change mother boards between note II variants I think you could be successful...but again..I could be wrong...see some note II tear downs on YouTube between note II variants..and do the judging by yourself

On Verizon, will it work and any links for this specific version?

Hi guys. I've been a member of XDA for some time through many phones rooting, ROMing, etc., and customizing many phones. But I haven't done anything for awhile, still rocking the Note 4, and am by far no expert. I am really looking to get my hands on the Xiaomi Mi Max 4GB 128GB dark grey version. I've never bought a phone that wasn't compatible or made for my carrier, so I need some help.
1. Does anyone know if they will get these back in stock, or am I stuck purchasing a gold one?
2. I am on Verizon. From my understanding, it will work except LTE. Do you still get 4G but not LTE? Is it a huge deal really? Can you still stream on Netflix etc, without a huge lag? I've read from some users online it wasn't a huge difference.
3. Which version do I look for, International?
4. Would it work better on AT&T? Because I am willing to switch for the phone I want. If it's the same as Verizon, no LTE, then I'll just stay with Verizon.
Thanks for any help guys. I really want this phone. I was disappointed the Note 7 is still so small. The Note 4 easily fits in my pockets, so I can't see why they won't go bigger with all the use of media and internet these days. I know some people wear skinny jeans and already have an issue with the size, but that's why they have other options like the S7.
Also looking into the Asus Zenfone 3 Ultra. Will that work any better on a US network?

I'll pay you $1,000,000 if you can get Verizon to activate this phone on their network. They would never let you use any of these phones on their network.

I thought you could use it if you put in the APN and stuff, but just not get the LTE? I guess not?

They block it from accessing their network. They limit what's allowed to run on their network. I even tried my friends Verizon sim in my Mediapad X2 and Mate 8 and nope, if it's not in their whitelist it won't work. That's one of the main reasons I left Verizon a while back.

Ok, few important things to share with you.
Consider the 32gb, 3 gig ram version because it has the most development, global ROM, and possibly lower cost. I'm seduced by bigger specs models but frustrated to no end by lack of global ROM, I've got the 64 gig.
Secondly I ditched Verizon for this very reason. Lack of open network and hassles getting devices to work.
Thirdly, look at network coverage in your area, pick the better of AT&T or T-Mobile. I've gone with T-Mobile and not looked back. Speeds are good enough at H+.
Finally, Lenovo Phab Tango device with US LTE bands is about to hit the market, so research that also. ?

THANK YOU so much!!! That was awesome information. Lenovo Phab 2 Pro, seems to be the only fairly current phone over 6.3" fully compatible in the US right? I've had so many cell phones over the last 15+ years, more than 15. I've never cracked a screen. But with having such a larger screen, it concerns me a little I have not seen anything about it being Gorilla glass. Other than that I'm sold. Not that there are many choices in that size compatible in the US, but it has pretty good specs overall. I only wish for a little bigger battery and Gorilla glass. But you sold me sir. I'll be waiting for this. Guess I'll be switching to AT&T soon. Thanks!

I have the data and sms/mms working on Verizon currently. Did all the troubleshooting with them and on my own. Not your typical customer, 32 years in technology network engineering. Been fighting with them to have it added to their system. Finally someone submitted the form for me waiting to see. As for now I have my Verizon number forwarded to my Google Voice.
