[Verizon Galaxy Note 4 General] radionerd:
Don't lock your BL again, LP or MM retail TAR's will trip the efuse, rendering your backup of aboot useless. No going back!

If you flash retail MM, or LP, your DevEd phone will be "retailed". Locked BL, no root, no way back to DevEd short of begging Samsung to fix at their discretion.

Once MM rolls out to Retail Verizon note-4's, it should only be a few days before someone will make a DevEd safe version of MM for us.

Be patient, and be careful.
[Verizon Galaxy Note 4 General] ryanbg:
I strongly advise you follow radionerds advice. Once you upgrade, you can NEVER go back to Developer mode. While it's probably possible to do what you're suggesting, it's not even close to worth it.
[Verizon Galaxy Note 4 General] stueycaster:
Just be patient. The word is MM for the GN4 will come out next month. Even if it runs late it'll still be worth the wait. Don't screw up the best phone on the market that you paid a ton of money for just because you don't want to wait.

[Galaxy S 4 Q&A, Help & Troubleshooting] isnull:
Hey everyone,

Please bare with me, this is my first time rooting & flashing a smartphone, so my knowledge on the topic is still limited even after some reads.

I also have the "misfortune" to not fall into the (apparent) easier route of having a non-Canadian Galaxy S4 where the model starts with "i950.." but mine being SGM-i337m. From what I've understood, the only reliable method I could use would be CF-Root, as described in this thread (OP's post), although the thing that bugs me, because I'd like to be able to install whatever ROM I'd like, is the line that says "[..] and those who want to keep as close to stock as possible. CF-Root is meant to be used in combination with stock Samsung firmwares [..]".

Also, which might be worth mentioning, my best bet is I'll probably end up flashing Cyanogenmod's ROM and they seem to have packaged installers, but I'm still worried it might not cover my model (if I take that route instead of rooting using CF-Root). From CGM's wiki under Supported Devices, there's a list that includes "jfltecan" (code name) for Canada, but I'm still hesitant. Do you guys think it covers Koodo (service provider) which I believe is owned by Telus (another SP) ? The last thing I want to do is brick my phone or have it unusable at the booting stage or whatever. And I don't mind reading, so any helpful links which covers this specifically would much be appreciated, although I don't mind an all cooked answer :)

Thanks

[Shield Tablet Q&A, Help & Troubleshooting] bigcletus:
Down to 15% with only 3.5 hrs screen on time. Mostly just web browsing and a couple of brief games. I keep the brightness down low too. Is this normal?
[Shield Tablet Q&A, Help & Troubleshooting] Judge584:
No this is not. If it is a new unit then do a factory reset. If problem persist just RMA it. I had same problem and only a RMA can save you.
[Shield Tablet Q&A, Help & Troubleshooting] bigcletus:
I had already tried the factory reset. I am rooted too so not sure if they will allow RMA.
[Shield Tablet Q&A, Help & Troubleshooting] Judge584:
Just unroot it ;).

A test to be sure: factory reset, then just add your gmail account but refuse to restore any apps. Don't touch any settings except screen brightness to 25%.

Then use your tablet for web browsing. If you're not able to achieve 6hours sot at minimum before your battery died, then for sure you have a faulty unit. And only RMA can solve this.
[Shield Tablet Q&A, Help & Troubleshooting] bigcletus:
I did not think it could be unrooted without unlocking bootloader , and flashing factory image. When i did the factory reset, root remained. The screen flickers too so maybe it is just a bad unit.
[Shield Tablet Q&A, Help & Troubleshooting] uuang:
Don't worry about root. Evidently the bootloader has to be locked except in cases of cracked corners but they don't seem to care about root. This isn't Samsung.

You should be able to get much much longer battery life though so RMA is your best bet.
[Shield Tablet Q&A, Help & Troubleshooting] CM17X:
SuperSu have an option just right there to fully unroot your device. There is not need to unlock. And even if you unlock your bootloader i don't can't see any grip for nVidia to deny your warranty because of the battery draining. Is not related to your bootloader instead you've installed a custom rom.
[Shield Tablet Q&A, Help & Troubleshooting] bigcletus:
I saw that unroot option but did not want to take a chance on it. I was still within 30 days so I just returned the tablet and ordered a new one. Hopefully the new one has a better battery.
[Shield Tablet Q&A, Help & Troubleshooting] James_Feltham:
I am having the exact same problem my shield. The battery life is awful and the max I have got out of a full charge is 4 hours screen time on low brightness
[Shield Tablet Q&A, Help & Troubleshooting] CM17X:
It's really hard to tell you what's going on with your battery just by one screenshot. You need logs and a software able to help you find out the culprits. Try BetterBatteryStats and/or Wakelock kernel and see which app is draining your battery.

On the other side, if you updated your tablet to lollipop and didn't performance a Factory reset, do it, and if you do it make sure you configure your device as a new one.

[G3 Q&A, Help & Troubleshooting] kipue:
Hi guys, I'm thinking of going to the G3 from my S4 in the coming week, and where I live in HK, I see we can get the models F400 (S/K/L) or D855.

I read around quite many roms call for D855 only, does this mean that you advise me to really hunt down this model (I think it's EU model?), or the F400 could be compatible?

I must say that I choose my phones a lot for the possibilities offered by XDA, and other than the OPPO One (my first choice, depending how hard it'll be to get one here), this is the second best large screen available in my price range.

I'm not familiar with LG hardware her on XDA, so I want to hear from you all before I commit.

[AT&T Samsung Galaxy Note 4] IcOpRo:
You have to call ATT and give them the IMEI? I had a S5 (wife has it now) from TMO and its unlocked and we just popped her sim on it without calling ATT and she gets LTE with no issue. Just wondering if its something new.

I'm thinking of selling my ATT note 4 so I can buy a TMO Note 4 myself
[AT&T Samsung Galaxy Note 4] mircury:
No, most of the time it just works. In a few cases as with the international Note 1, ATT had a range of imei's programmed wrong in their database so it showed up as a phone that doesn't get the correct data plan (missing LTE or HSPA data) like an old blackberry/flip phone. It took them a few weeks to correct it.

Most everyone coming from a phone that has LTE should just be able to plug in their sim card and go, never having to talk to ATT.
[AT&T Samsung Galaxy Note 4] soraxd:
No you don't have to call. In fact the general conscious is; doing so will get your LTE disabled by at&t. I would absolutely not willingly report my attempts to circumvent at&t's restrictions.

if you're going to make a new tmo on at&t thread, change the op to be a collection of known knowledge. let me get you started.

T-Mobile

Quad Band GSM; UMTS: Band I (2100), Band II (1900), Band IV (1700/2100), Band V (850); LTE: 1, 2, 3, 4, 5, 7, 8, 12, 17

AT&T

4G-LTE Bands 1, 2, 3, 4, 5, 7, 12, 17, 20, 29

3G - UMTS 850/1900/2100MHz

GSM/GPRS/EDGE 850/900/1800/1900MHz

so what are bands 20 and 29? they're international bands not implemented in the US.

Known Issues using tmo N4 on at&t: no HD voice (supported by at&t as of 12/3/14)

cheapest off contract I've found new black: $699.99

[AT&T Samsung Galaxy Note 4] mircury:
Ya, I did a guide a while back here for the Note 3. I think a lot of people found it helpful with over 700 posts. It would be good for the note 4. Feel free to take anything from it you want.
[AT&T Samsung Galaxy Note 4] tbong777:
I didn't HAVE to But I was running Wap. Cingualar APN on the Note 2 so they had to provision me to work with the Phone APN for LTE. I had an ATT S5 IMEI ready if the native APN did not work as well as a new SIM card.

I asked if there were any signal losses since it was not an ATT phone . He said "only thing I may miss are the ATT apps"'. I have a couple I use like Visual Voice mail. and the account app. Otherwise I am ok.

Did have to freeze the T mobile wifi over phone app s I was getting an error message everyday as that app tried to find T Mobile towers.
[AT&T Samsung Galaxy Note 4] mircury:
LTE band 20 is for ITU Region 1 EMEA (Europe Middle East and Africa roaming).

Band 29 is for carrier aggregation with band 4 in the US. (Band 29 is download only). It is implemented in a few large cities so far, Chicago being one. It is for capacity only; not speed. The n910t does not support it, but it's not a big deal at this point because it supports the normal LTE bands offering the same service.
[AT&T Samsung Galaxy Note 4] tbong777:
Great Idea done.

Swappa is a good place for used devices as well. No Ebay fees and most are new resales. No need to deal with T Mobile at all
[AT&T Samsung Galaxy Note 4] tbong777:
I did not find this to be an issue, after I gave them my T mobile IMEI. There are no phone restrictions.

They did not try to take LTE away and they did not care where I got the phone. They only want the service. I asked about that and was told things have changed and they are not penalizing those who buy elsewhere. They don't sell phones for profit and make no interest on those NEXT Plans. I think they want to get out of the $299 two year contract phone business and just sell service. In my case if they did not make it work, I was ready to jump to a developer Phone on Verizon. So the tech really wanted to make it work and he did,

I am using the same LTE APN as an ATT Phone,

They just have to be able to provision them for LTE, If you are coming from an LTE device you likely would not have to do anything but put the SIM card in.

My phone does not show up as a Black berry. So far just a unknown flip phone. I am disappointed with LTE speeds here. When the phone says LTE I get about 10 down. Verizon does about 23. ATT LTE is very spotty here. I use my wifes ATT S5 as a reference. Her phone does not get better than mine.
[AT&T Samsung Galaxy Note 4] IcOpRo:
I think if you give them the IMEI also the phone will register in the ATT website as a note 4, don't think it will show the picture of a flip phone. ;)

This helps with insurance claims if something happens. If I'm not mistaken

Also [MENTION=2993323]tbong777[/MENTION] could you fix the band 29 info in the OP? It should say it's for carrier aggregation in the US and not international support. Thanks!

I gave them my SM-910T IMEI and it shows up as a flip phone however I still show 4G LTE downloads where I can get LTE and the speed tests confirm its not standard 3G HSPA+

There have been mixed reviews on which IMEI to use. I got one off a demo S5 just in case and will keep it ready if I need it bit so far so good with my 4 year old SIM chip and 910T IMEI.

I would say if anyone is going to go this route you will have to be ready willing and able to buy a phone as warranty service would be doubtful. The good news is the phones are getting cheaper. For $200 I am keeping my International N7100 Note 2. Its worth more to me as a backup than the $200 I may get for it
[AT&T Samsung Galaxy Note 4] soraxd:
all of our information seems to conflict, where are you getting your information from?
[AT&T Samsung Galaxy Note 4] tbong777:
I noticed the same thing but the important thing to remember is our T Mobile phones are working on AT&T in LTE mode.

I could not sort out all the information. But as more people chime in with 910T devices , some of those questions will be answered, I was confused researching and looking at "bands" etc. but what sold me was the real time users who were not having issues. I bought mine knowing I could sell it if I was wrong.

The only way I was going to find out for sure is buying a phone and decided to try it out on my own because there was some conflicting information. I had had no issues using an old Note 2 SIM on wap.cingular even giving AT&T the IMEI of T Mobile's phone. After inputing the LTE APN and having the tech ensure the provision was correct I was happy I test it against a know ATT branded LTE device and can confirm it works.

So I would not get too hung up in drilling down into the bands and frequencies at this point. Many of us are using the devices on AT&T without issue. Those who are having issues may get some help here.
[AT&T Samsung Galaxy Note 4] mircury:
LTE info:

LTE info including international band 20 roaming info is from here. It also show which blocks correspond with the bands.

Band 29 info is below. Fiercewireless is an telecom industry publication.

AT&T carrier aggregation plans/Mobile world Congress presentation here and here.

All LTE bands listed with their corresponding uplink/downlink frequencies. Some people only list the frequencies so this helps to find what band they are talking about.

UMTS info:

USA Cell frequencies in use here.

Phone info:

N910T info is from the back of the box and FCC reports.

[AT&T Samsung Galaxy Note 4] IcOpRo:
Actually I was surprised that I didn't even had to put the APN. When I went to the network settings and AP settings there was already the ATT Phone APN in there. I just selected it and I got Data.

Is anyone using square trade to insure their tmo phone since I'm pretty sure Att would not insure our phones
[AT&T Samsung Galaxy Note 4] IcOpRo:
I'm wondering if there's a way to get the phone to show up on your ATT account webpage. The insurance company that ATT uses insures the line, if you go to their website and go to the steps on reporting a lost or damaged phone you will Hey to a parte with a drop down that shows the devices you have used in that line. As long as the device you are reporting is under the 90 day policy you can report it.

So if there was a way to get the device to show on your ATT account page the insurance will work.

I had a CAN S4 a while ago that did show up the picture of a S4 on my ATT page.

You can flash the update via ODIN when it gets released on Samsung. Or you can root get TWRP and flash the stock ROM when someone post it.

what do I have to do to get the phone unlocked ? I read around and said you need to pop in a TMobile sim card first on initial start ( for region lock purpose ) ?

Can I just insert my AT&T sim card to turn the phone on and get the IMEI for the unlock code ?

Any one have a decently priced unlock website/ebay that they use?

I don't think you need to put the TMO Sim card first. Place the ATT Sim card so that it would ask for the code the insert the unlock code.
