How to root AT&T Nexus 6

Is there a thread on here on how to root the Nexus 6 with AT&T carrier, running stock Lollipop 5.1? Or rather, what is the simplest way to root? I already ADB and the necessary USB drivers installed.

Same technique as any other Nexus. Either use a toolkit or CF autoroot or my preferred way of using fastboot.

I've actually heard that some methods can't be used if you're tied to a carrier. Something about something on the phone being locked.

I used a toolkit with no problem and I am on Verizon.

Let's clear this up.
On an android device there are 2 things that can be locked.
1 - SIM lock. Some carriers lock this as they subsidised phones so they only want you to use it in their network
2 - the bootloader
On some other android devices, some carrier versions have either a locked bootloader or an unlockable bootloader, when other versions of the same phone do not.
However, unlike other android devices, there isn't any difference between the carrier versions. There are only 2 models of nexus 6. The North America version and the international. Both models are identical hardware wise, except different radio bands.. The carrier "versions" are all the same except logos, boot animations and sounds. That's it.
On the nexus 6, they all have a locked but completely unlockable bootloader. There is one process for root. Unlock the bootloader, flash a custom recovery then from there either flash a ROM or flash a SuperSU.zip

This would be news to me and I've had the phone since it launched on Sprint. AFAIK, the phone is rooted/unlocked in the same manner regardless of carrier. The AT&T version is Sim locked and possibly Rogers as well. That's it.

well said!
but one correction. when flashing a rom, well most but not all roms, you also have to flash supersu for root. or you wont have root on that rom

Good point. What I should have said is flash a rooted ROM.

Okay, I get it now

So which is easier and safer to use: CF auto root or the Nexus rootkit? Do these work regardless of Android version?

Source for phone with unlocked bootloader

I am looking to buy an S4 Active with an unlocked bootloader that will allow flashing of custom ROMs. I have found a vendor in Hong Kong that appears to be selling the S4 Active with either what appears to be the AT&T configuration ("i537 For ATT"), or a non-ATT configuration ("I9295"). Can anyone confirm that this is what the "I9295" is and if it will work with North American GSM networks? Is there another avenue to get an S5 Active with an unlocked bootloader that I am missing?
Here is the link to the vendor and phone.

The i9295 has the unlocked bootloader that you're looking for. I bought mine off eBay for $200 but had to weed through a ton of items claiming they were the i9295 but in reality were the i537. I used the i9295 on AT&T and am currently using it on T-Mobile. It works great, however you only get HSPA+ and not LTE, I'm trying to figure out it it's just a modem issue where I can just flash the i537 modems but I haven't been able to spend enough time to really figure it out.
If you want an S5 Active with an unlocked bootloader, try searching for the SM-G870F. It's the international version of the S5 Active, so theoretically it should have an unlocked bootloader. There are people posting on XDA who have this phone, so you might want to try asking them.

Thanks for the response.
I just pulled the trigger on one of these.,
http://www.ebay.com/itm/111235467917
I have confirmed w/the seller that it is a T-mobile unit.
In theory the bootloader should be unlocked.

There is no such thing as a T-Mobile version. That is an i537, an AT&T phone. IT DOES NOT HAVE AN UNLOCKED BOOTLOADER. You can see the AT&T logo on the back cover. The phone has been SIM unlocked to work on T-Mobile, but the bootloader is still locked. This not the phone you want. If it's not too late I would cancel the order.
EDIT:
Try this one: http://www.ebay.com/itm/Samsung-Gal...406?pt=LH_DefaultDomain_0&hash=item1c56327bfe
Or this one: http://www.ebay.com/itm/Samsung-Gal...444?pt=LH_DefaultDomain_0&hash=item2803e961ec

Thanks. I suspect that even though the seller said that the bootloader is unlocked and it is a Tmobile phone that you are 100% correct in your assessment that it's only carrier unlocked. I sent a similar message to an S4 Active motherboard seller in California who also told me that all of their mobos had unlocked bootloaders. I strongly suspect that most vendors have no idea what a locked bootloader is...

You're right. If you want to be 100% sure you are getting an i9295 with an unlocked bootloader, have them send you a photo of the phone's About screen showing:
Device Model
Baseband version
Kernel version
Build number.
Those should tell you whether or not it is an i9295, particularly the baseband version which is linked to the bootloader. The other information can be faked if they know what they're doing, but the baseband information is pulled directly from the modem and there is no way to fake it on the i537.

Thanks for the information.
So am I correct in assuming that all non-ATT phones have a Device Name/Model number that is SAMSUNG-SGH-i9295?
What is specific to the non-ATT phones in the Baseband version?

Locked Bootloader = SGH-i537 (AT&T version)
Unlocked Bootloader = GT-i9295 (international version)
The i9295 baseband will say something like "I9295XXUCNE5" while the i537 will say something like "I537UCUCOC6". There an entire list of i9295 firmware on the Sammobile site in case you want to check where the exact baseband is from. So basically as long as it has i9295 in the baseband it is safe to assume it has an unlocked bootloader. When I was looking for my phone the first thing I did was look at the picture to see if it had the AT&T globe on the back cover, if it didn't I then asked for the photo showing the About screen to confirm. As long as both of those things check out I say you have a 99.9% chance of getting the i9295. You're probably going to have better luck with sellers in Europe because that where a majority of the i9295 sales occurred.

Just got my LG V40. Is it better off to cross flash it? Can I do anything else to it?

So I just got my sprint V40, Model Number LM-V405UA
android version : 9
Android Security Patch: March 1st 2020
And the software version is : V405U20d
Are these all up to date on my model?
______________________________________________
2nd question
What exactly is the benefit of cross flashing the phone with US unlocked KDZ or ATT Unlocked or any other KDZ?
What do you gain from doing it?
is there anything else I can do with my phone to improve it?

1) Yes.
2) & 3) More bands available to you/better compatibility for when you decide to leave Sprint for another carrier (make sure the phone is SIM unlocked first!), plus the ability to connect to more towers if you travel to other countries. Less Sprint bloatware.
4) Unlock bootloader and root device. Take full control of the tech you own!

I dont actually have sprint, I have Tracfone as my carrier and use the AT&T sim card
which KDZ would be best to use? I looked at LG Firmware and saw US Cellular but there's also the US unlocked one too
The only information i've seen about rooting and unlocking the bootloader is to contact someone that has a octoplus box

If you crossflash use the US unlocked.
Look here for unlocking the bootloader.
Once you've done that, rooting is as simple as using TWRP to load Magisk.

Get the US unlocked KDZ. I also had the Sprint model. Crossflashing to the US unlocked allowed me to use wifi calling and the additional bands for T-mobile.

A71 SM-A715F/DS and A-716U questions

is the unlocked A-716U rootable using magisk and does anyone think there will be development on it(ie Custom recoveries ? One last question one this specific model; assuming root is possible on unlocked would it be possible to get a carrier locked version (cost saving) and reflash firmware similar to oneplus's MSMtool?
lastly is the A71 SM-A715F/DS root-able with TWRP support?
Thank you
ps
I will also contribute to bounties
everyone is going to say/think "search the forum!!!" but unfortunately the posts available dont list specific model numbers when talking about successful root/custom recovery,.

U.S. variants usually can't be unlocked and therefore you can't install custom stuff like magisk patched files.
That used to be the case until recently that a person was offering bootloader unlock as a service to many 2019 and onward devices, as you can see here: https://forum.xda-developers.com/t/sampwnd-usa-model-bl-unlock-info-u-u1-w.4201689/
But, you would have to ask if the A71 is supported. It probably would need to be tested, but the owner of the thread was quite confident that it could be possible.

Oh okay, so there is no MSMtool like with oneplus devices where you can just change to international firmware? If so if there an international 5g version of the a71 (any a-series) with 5G? sorry the model/SKU's for samsung devices is confusing and there is an insane amount of them.

I'm sort of guessing that's the Odin equivalent of Samsung devices, not sure I've never owned a OnePlus device.
You can use Odin to flash different firmware on the device as long as it's the same SoC. For example, I've flashed Galaxy S9+ Unlocked firmware on my T-Mobile Galaxy S9+. One is variant SM-G965U and the other is SM-G965U1. However on this case, both firmware were US. One was unbranded U.S. firmware and the other was T-mobile branded firmware. I've also flashed Poland firmware on my Mexican A71, they're both model SM-A715F on this case.
I don't know if there's an international variant of the A71 5G. I guess you'll have to look that part up on your own. I think there is though.

The MSM tool enable users to take a carrier locked oneplus device and unlock it among other things. can odin unlock bootloaders ?

Not really. Odin can only flash firmware, either stock or custom (you use it to flash TWRP and then basically everything else you flash with TWRP).
And no, Odin doesn't do any bootloader unlocking, any unlocking is done with the device itself. But as I mentioned, U.S devices aren't unlockable out the box.

when you say "out of the box" do you mean there is NO possible way to unlock them or it takes a process?

There is no possible way to do it... for free as of now. If you want to unlock the U.S. variant you have to do it via the paid service I pointed out and thats only IF it works (as I mentioned, its been untested on the A71)
In comparison, you can buy the F variant, turn it on, head to developer settings and select OEM unlock and then unlock the bootloader.
If we ignore the paid service, sampwnd, that I pointed out in my other response then it is impossible to unlock the bootloader of the US variant and therefore, impossible to root.

how much does the paid service cost and do you have a link? i didnt see you mention it before. also do you have the aseries discord invite or telegram?

SM-G973u1 snapdragon root

Sorry to just drop a question, but I can't find the answer. Can the snapdragon S10 SM-G973u1 bootloader be unlocked? If not is there another way to root it?
Thank you
Chris

HelloChris333333, just when you post on a forum the courtesy of saying hello. Yes you can root just with the firmware of your model S10 SM-G973U1 US model so not compatible with EU firmware.

I'm not sure that's true, but I would love to find out I'm wrong.
In my research, the SD phones cannot be unlocked unless you are on (and remain on) an older BL version. The last unlockable BL version was 4, as I recall... if you're running updated firmware you are likely on BL 6. Even on 4, the process was not free and once you did it you could not update to a newer version of FW without losing the unlock.
For this reason, I gave up on getting root/BLunlock on my phone... and honestly, I have not missed it. This is also why I have not seen much development of FW for the SD phones anywhere.
Again, if I'm wrong, I'd love to learn how it's done!

Hello meric57
Can you share a link to the firmware I need? I just bought this phone and there is no OEM unlock option, it is a US phone. If I cannot root it I will have to sell it and get another phone.
Thanks
Chris

I guess another question would be where can I get a S10 with the Exynos chip?
Thanks
Chris

Using ADB I keep getting "waiting for device" and then I find I need to unlock the bootloader. This crap is an endless circle.

U4 can be unlocked before , I can unlock it , Special engineering documents need to be made

I'm V6 nothing available. I bought a G973F instead. G973u1 going on ebay.

Exactly, there is really no root/unlock for snapdragon phones unless you're on a very old BL (and you have to stay there so you can't update). IMO, that's not "can be unlocked" even with "special" steps, particularly since most phones today will have newer BLs (even a year ago, I couldn't find a BL4 phone)... but, yes, it's technically true to say it can be unlocked, but only in very limited cases.
@Chris33333 For this reason, I get that you may want to go to the Exynos instead... I'm curious, if you're in the US, how does that work with carriers? Does it? I've found most US carriers refuse to activate phones that don't match their list of "compatible" IMEIs... I imagine an F-series phone won't be on that list.

I'm in the US using Straight Talk with T-mobile. I've had a Galaxy S5 rooted for years. With straight talk I can use AT&T, T-mobile, or Verizon. But this international phone does not do Verizon.

And StraightTalk will activate the F-series phone without complaint or issues? If so, that's great to hear... because I know VZ and ATT typically won't...

I haven't put the SIM in it yet. Still trying to delete all the crap off the phone.

Lol
