[Q] Coming from int'l to att - AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin

Hello all,
I'm coming from int'l i9505 to att version (long story). So I've got some basic questions... First of all, it seems that the bootloader is locked, does this imposes any real limitation or is a just a matter of unlocking (through loki, i suppose)? Can I upgrade baseband firmware freely or should I stick with the current one? I'm missing the "Cloud" account which provides sms backup and picture sync (with dropbox and picasa), can I flash any int'l based rom which provides these features (after unlocking, of course) ?
Cheers

decision to buy htc one developer edition

hey guys .i just pre-ordered htc one developer edition.what do you think i get the benefits purchasing the developer edition instead of at&t version.
do you think it works with at&t and t-mobile lte networks ?
will i get the software upgrades first like the international version ?
normally the at&t version device get upgrades very late compared to the international version devices.i always wanted to buy a device which works on every kind of gsm networks(hspa+,4g and lte ) in usa and internationally(3g,4g and lte).and which gets the software upgrades right on time .i thought this would be the one .
someone clarify me the choice i made was right

If you want non bloated att software, possibly faster updates, and bootloader unlockable.
Lte will work for both networks.
Updates will probably be quicker due to the fact that there is NO carrier testing. So updates should be fast as the international version.
Sure why not!
There is an entire thread dedicated to this. The dev edition had an unlocked bootloader and SIM. It will only function on AT&T correctly at the moment, but later this year tmobile should have enough of their lte and refarmed hspa network up for it to work properly on there.

The benefit of the Developer Edition is the unlocked bootloader (allows you to use custom ROM), and the unlocked sim (which ATT won't unlock for you even if you buy outright).
Since it is a non-branded handset, it should allow you to upgrade your software like the international version, although this is not as important if you use custom ROMs (since Custom ROMs usually updates as new software is released).
The Developer Edition will work perfectly with AT&T for HSPA and LTE as it is identical besides the branding and unlocked status. It will likely work with T-Mobile's LTE when it's ready but will not work with the 1700mhz HSPA+ network. It may however work in areas where T-Mobile uses 850/1900 frequency (Not everywhere at the moment)
So in terms of advantage over ATT version, the Developer Edition is much much better as it allows you to use customs ROMs (since you are here asking the question, I would assume custom ROM is something you would like to use). SIM unlock is not important to everyone as most will stay with the network anyways, but the lack of custom ROM ability flat out makes it the less desired version.

Well, you asked the questions and I answered them for you (the differences should be black and white for you). Whether or not if it's the right decision is up to you.
32gb or 64GB? Worth the extra cash?

Hi:
I know this thread is about the dev edition but I was wondering if there's any other difference between the 32gb and 64gb dev edition? I know the dev edition has unlocked bootloader, but couldn't we achieve the same thing on the 32gb unlocked edition using this method (htcdev), or am I wrong? Thanks for your help :fingers-crossed:

Yes, it can be unlocked via HTC Dev. Only the AT&T branded devices will be blocked.
Edit: according to your post title, you're asking if dev edition is worth the extra money? YES. Not even $100 more for double the storage.
You can unlock yes. Your getting a extra 32 GB basically

So the dev version doesn't have custom roms, or very little custom roms? If so why would that be? I love flashing roms, but this would be a real bummer.
Nevermind...I read it incorrectly. The Dev version does have custom roms. How are the custom roms different on a dev phone than lets say the sprint version?

The Sprint version of the phone has different hardware as it is a CDMA phone, not a GSM phone. You could potentially brick your phone by flashing ROMS that aren't for your specific device. Stick to this forum for your mods and ROMS/kernels.
Make sure that you install a recovery (CWM or TWRP, both located in the Original Android Development section), which is necessary before you begin to flash anything. Again, ONLY FLASH MODS FOR OUR DEVICE FROM THIS FORUM
this might not the right place to ask this, but does anyone know if HTC will be releasing a developer edition in black?

[Q] Flashing TMo Rom on AT&T

Hey guys,
I unlocked my galaxy s4 from AT&T and now I use T-Mobile. I was wondering if I could use the t-mobile rom since I would like to use the tethering and wifi calls from it.
I don't really want any custom rom, just because I'm fine with the carrier ones.. so I searched somethings and I figured out that I could use the t-mobile rom with loki doki.
Can I just instal the stock firmare of t-mobile? (It would be the M919UVUEMK2)
By the way, right now I'm running the MF3 and idk why I don't receive the OTA update (never received, I suspect that's because I unlocked it)
I found some other posts but unfortunately it doesn't contain enough information.

[Q] Which GSM version is most "hacker friendly"? What are the tradeoffs?

I'm frustrated with the locked bootloader and lack of developer interest and no Ant+ on the latest update so I am going to buy a phone that does not annoy me. Note 3 is my leading choice but I am also considering the Xperia Z Ultra Google Play Edition.
Right now, I've got more money than time. I have tons of good paying work backed up and I would rather pay for what I want than try to stay one step ahead of some carrier's control issues / bloatware.
I'm on AT&T with a grandfathered unlimited data plan. Don't really need LTE but will take it if it makes no difference. I do want at least HSPDA.
I'm willing to shell out the full cash price for an unlocked phone with an unlocked bootloader. What I really want is a phone that will get timely updates from the manufacturer and won't try to shove a locked bootloader down my throat later. It would also be fantastic if I could get a USA warranty in the deal but I can live without that.
So is there a significant "hacker friendliness" difference between the various models? If I give up AT&T LTE frequencies for the international version, what am I getting in return (besides the obvious international frequencies)?
Thanks for your time,
David

A limited unlocked bootloader if you choose the N9005. The N9005 has the better development options -
However, the N900w8 (Canadian/Mexican model) has a complete unlocked BL for upgrade/downgrade 4.3/4.4. - Runs most, if not all N9005 ROMS also. - Probably your better option IMO at least -
N900T - T-Mobile similar to the N9005 but BL cannot be downgraded as freely as the N900w8
You will have to sacrifice LTE though, but as you said you aren't fussed about LTE - you should still receive 3G/H+ without issues.

Why would you want to downgrade the boot loader, to be able to switch to a rom that depends on an older kernel / bootloader? Or is there some other reason?

At first most wanted to due to CM being incompatible, however now that CM runs on the new bootloader most don't want to. - The few remaining I guess prefer 4.3 due to different errors they have had or problems on/due to 4.4.2

[Q] Considering S5-G900T for AT&T, can I update OTA?

I'm looking to get an Galaxy S5 for AT&T, and am wondering how I would update my ROM when using the G900T (T-Mobile)
My understanding is that the G900T comes with unlocked bootloader. I would be getting that model for specifically that reason "just in case" - i.e., if down the line I want to use an alternate ROM.
In the meantime, though, I want to use whatever the most "official", straightforward (i.e., "most approved") ROM I can, even if this means being "behind" on the latest and greatest.
Does this mean that I use the T-Mobile ROM? Or the AT&T ROM? Can I update OTA (as is my preference)? If not, what would be the most straightforward method of updating the ROM?
you would need to get a sim-unlocked G900T, and then you can just put your ATT sim inside and it works.
Not sure if you'll receive any OTA updates if you're not using a tmobile sim though. Most of the newer phones are already on 5.x, you you'd be pretty current.
I got an unlocked G900T last week and put a custom touchwiz rom on it from the att dev section, and it works just fine.

Which GS5 to get - AT&T, Sprint, T-Mobile or?

Looking to pick up a GS5 and put on Nougat via LineageOS. Is there a certain carrier's phone that is more desirable than others? Since I do not already have the phone I would like to acquire the best one to get to my ultimate goal of unlocking and putting on Android 7. Phone will eventually be used on the AT&T network.
Thanks in advance,
Bob
Try and see if the international G900F works on AT&T, or simply get the G900T, to not go through the hassle which involves an international version.
If you like using custom roms and such STAY AWAY FROM AT&T!!! Bc they lock there bootloader's haha
AT&T Galaxy S5 has Locked Bootloader, which means you can't flash custom ROMs. Sprint variant has different hardware for CDMA support, so some ROM may be incompatible. If you can invest on G900F (International Version), G900F is the most ideal one for custom ROMs (Or G900W8, which is Canadian version) Otherwise, you would want to get G900T since it has unlocked bootloader.
