SM p607t root/custom roms

Is any method of root or custom ROM compatible with our T Mobile Samsung Note tablet? Coming from a HTC one m7 where all rom were compatible other then CDMA/ GSM
I've used the towelroot but really looking to install aosp on this thing already

Your best bet is to ask in the rom thread. I have yet to flash anything on my P607T other then rooting. It looks like Dev work is very slow for this tablet. So you may not get a 100% working AOSP rom any time soon. Stock rom is really fast and sable once you root and deboat it. That is what I am sticking with for awhile.

I'm looking for ROMs too. But I think I'll stay with stock for now. Any recommendations on what apps to debloat?

Your best way is to just use TB and froze whatever you do not want. If you run into problems just unfroze it. If you uninstall and you run into a bootloop you will need to have the stock Odin firmware ready. here is a link to get the stock odin file.

I just uninstalled whatever I did not want. If you google What apps are safe to remove on a Note 3 to debloat, it will pretty much be the same as the 10.1. Both the note 3 and the 10.1 are pretty much the same other then screen.

unlocking bootloader
I think we need to get the bootloader unlocked to get development on this thing rollin'
I'm willing to lend my device to a well-reputed senior-member/developer and pay shipping both ways if they think they can work some magic for the SM-P607T
Should I make a new post with regards to this?

Was able to root using this method no Knox either

bootloader is unlocked and there is no problems getting root and current Twrp can be installed which says the bootloader is unlock. if the bootloader was locked you wouldn't be able to flash Twrp. from the looks of it no one has a p607. it is all 605 or the wifi only one p600 and 601. stock rom with root and debloated works great. try a 605 rom. hopefully CM starts to pick up more then we are set.

Do P605 ROMs even work on a P607T? I've been wondering that myself. I have a 607T and although I am very impressed with the stock ROM it just is never going to measure up to CM for me.
I've been thinking about giving the P605 CM 11 port a try in a few weeks when it's just a bit more stable, but I have no idea how similar they are or if my device would even boot after flashing it!

Guys... Did you even read that thread in the link?
You should be asking these questions there... That whole thread is dedicated to making calls on the P607T.... And if you read the thread you'll know the author hit a brick wall and a boot loader hack is needed to flash the proper modem files for phone calls.

Haha. Thank you kcrudup for pointing to that thread, gave me some useful info on using P605 Roms on a P607T.
Any idea about what sort of problems may pop up from doing this? I got a reply in the CM thread that their P605 version of CM should work fine on my P607 but... Surely it can't be that simple? Any idea what differences there are between thecode of the two tablets or is it really that similar?

I'm 95% sure the only difference physically is the radio "front end" hardware is tuned for the T-Mo LTE frequencies so the modem baseband SW reflects that, and software-wise all that's new is a few pre-installed apps like the "My T-Mobile" app and that (loud-and-annoying-as-hell-and-quickly-removed) T-Mobile "jingle" on startup; I've put several P605 ROMs on my 607T and everything's worked OK ('cause the bootloader won't let me overwrite the radios and potentially-dangerous bootloader files anyway).

Awesome info thanks so much!! So if I understand correctly, any differnces that would render my tablet completely inoperable are already protected from flashing? So I don't need to meet with the TARs for the Roms to remove the modem files or anything?
I mean, I don't mind if my radio breaks or something, I can handle flashing back to stock I am just never sure when I start flashing a new Android device what risks there are of bricking it completely (which, with Knox in the picture, could totally screw me).
So with that I will probably be going flash crazy tonight and tomorrow to test our some different 605 Roms starting with Cyanogen. I'll try to post any findings or quarks here or in those threads!

You will have to remove all the "*.mbn" and "*.bin" files from (Samsung-supplied) non-P607T ROMs, though- Odin will abort the flash if it receives a bad status from the bootloader when the bootloader rejects the flash operation. But it should be a straightforward unzip/rm/zip operation to repack, and I'm sure the CM flashes are just "boot" and "system" (and possibly "recovery") partitions anyway.

Yes it is necessary, the .mbn files relate to the bootloader and the .bin files is the modem and NON_HLOS, being that they are for a different ROM it could cause major problems and maybe even bricking. @kcrudup even mentioned the bootloader conflicting with Odin if the device models don't match, so it seems you won't get the 605's installed without removing said files.

I have been looking for a guide for flashing twrp onto my sm-p607t but i cant find one. I mainly need the correct twrp img.tar file for odin. I found this one ( openrecovery-twrp-2.6.3.3-lt03wifiue.img ) but I don't know if it is the right one. I used towelroot to root it and i used the proper supersu to disable knox so i just need the custom recovery now.

[Q] Upgrading Samsung SCH-I435 to Android Lollipop

I haven't found any information for my specific model for some reason.
What I want to do is install stock Android 5 (by stock, I mean what comes on the Google Nexus) on my Verizon Samsung s4 mini (SCH-I435).
To my knowledge, this would involve:
Rooting the phone
Finding a compatible ROM
Flashing the ROM
I just can't find any guides or ROMs for my specific model. Can anyone here help?

I have the exact same model of the s4-mini as you do, and I've looked around just about everywhere. It seems that the bootloader has never been unlocked for this variant of the S4-mini. Verizon also just released a new firmware update that patches the kernel, preventing the use of previous root methods, and it may be some time till someone finds a way around it. If you find anything, please tell me, as I can't stand this bloatware crap on my phone.

How do you usually unlock the bootloader?

Usually people create software, such as Cyanogenmod, that exploit vulnerabilities in the software on the phone, giving them access to the bootloader. One of the many issues with this variant is that it is distributed by Verizon, and Verizon is very vigilant about patching vulnerabilities.
EDIT: After a little more digging, I found that the bootloader is completely locked and there is a 99.9999999% chance that it will never be unlocked, typical Verizon for you.

Correction
You can root the SCH-I435 with towel root, install SuperSU and Busy Box from Play store. Then flash phils touch recovery and then flash a rom from SD card in recovery. Beware, if you are on Bluegrass cellular. Any rom must be for CDMA phone for the SCH-I435.

Where would I find a compatible ROM?

Definitely not legit. They simply have tons of links on their site to upgrading every single phone to lollipop. Inside of each page is exactly the same link to the same "ROM" for every phone, and the comments at the bottom of the page aren't actually real, they are just a picture. Try changing the number at the end of the link "...updateupgrade_70.html" and you will see what I mean.

I was able to successfully root my phone by flashing 4.4.2 NE1 (opposed to the latest version) via Odin and using Towelroot.
Has there been any progress on the addition of a custom recovery?

I found something interesting that might be worth looking into. This guy (http://forums.androidcentral.com/samsung-galaxy-s4-mini/527518-serious-question-needing-advice.html) claims to have installed a custom rom that was designed for the GT-I9195 on his SCH- i435. I have actually run into him before on other on some other threads and he seems to be legit. But the problem still remains that when he installed the rom his sound and mic didn't work. Still worth looking into though.

Just curious, would over of the international variant ROMs work if we managed to unlock the bootloader or would the SCH-I435 require its own specific one?

I found an app called Flashify that claims to be able to flash a boot loader or recovery to your device from your device.
Do you think flashing CWM or TWRP would work this way?

It seems that the only thing that this has to offer for us is a way to flash your phone without using a computer, and to back up your phone (I haven't actually tried restoring from a backup). But we still need a version of CWM or TWRP that is made for the sch-i435.

[Q] I am trying to unlock T-Mobile S4 from ebay

So, I recently bought a galaxy s4 from ebay, and it seems to work on the network, so I don't think the IMEI is blacklisted. However, when I tried the steps here http://forum.xda-developers.com/showthread.php?t=2282683 and here http://forum.xda-developers.com/showthread.php?t=2283068, I am unable to complete the process. When I do the latter, which seems more like what I did with my S3, I get the same message "unable to process request". I remember I was getting this message on my S3 when I had the SlimKat ROM on it. But when I look at my S4, it looks like it has the OEM ROM on it, so I am not sure what is happening. I looked at my boot loader/baseband, and this is what I have: m919uvufnh7. I know that with my S3 I had to make sure I used the correct ROM to flash my phone, so I could get it unlocked the free method. So, does anyone know what bootloader and ROM could help me accomplish these steps in the second thread?
I am thinking I should flash a different ROM on my phone.

Thanks for the response, but I have not tried it, because I don't think it is that easy. I also purchased AT&T tablets and tried unlocking them, but AT&T said they were 'active' under someone else. They were not not showing as stolen, but active. I am not sure what that entails, but I am guessing I have to register it under my account first, before I can request to unlock it. So before I try going through the long process of figuring out how T-Mobile can unlock my device, I thought I would give this a try. It seems simpler and since I plan on modding my phone after I unlock it, I see it as just part of the process. (At least I hope so.)

Alright, I was able to get mine to work, so maybe I will list my steps. However, I must say that I had some failed attempts (in part due to not understanding the post referred to by radoo7701) and some issues with my phone. But those steps wont be included. Also, my version was m919uvufnh7, not NK2. I would think it does not make a difference, as long as you reflash back to NK2 at the end.
1. I locaed the modem for M919UVUAMDL and m919uvufnh7 modem (as I did not make a backup of mine before starting)
2. I used Odin 3.07 to flash the AMDL modem
3. I tried the steps here http://forum.xda-developers.com/showthread.php?t=2283068, but this would not work, I could not even get the menu to pull up, as it would say request unable to complete. So I tried this http://forum.xda-developers.com/showthread.php?t=2282683 and that actually worked, so I went through these steps successfully.
4. Use cf-auto-root to root your phone
5. Download regionlockaway and transfer it to phone, then install it on phone and run it.
6. flash m919uvufnh7 modem and booted up with my AT&T sim, and it did not ask for unlock code. It just worked!
NOTE: I did have to use a T-Mobile sim card to do the menu process, but radoo claims that he did not do the menu portion. I had already done the menu portion when I finally got to reading his comment. So I can't say that it will work or not. Either way, his suggestion worked for me and I am content with the result!
Thanks radoo7701!

I was reading note4 AT&T thread and found this, like i said do not take any updates!
AT&T released an update with security enhancements yesterday, any word about this and how this affects us?
I am not sure. I know that I have my OTA blocked; however, I too find it interesting that a sudden security update is released now about two weeks after the Verizon hack is discovered and rolled out. It is stuff like this that tells me that their devs know something that we have yet to discover.

This may work for you AT&T guys.......
Plus, the tools to finish this are already public.
You compile SamsungCID (in a KitKat tree), and use it to change the CID using temp root, then you can flash the corresponding developer edition aboot via ODIN. The reason I haven't release it is that there is an easier method.
Ryan has a slightly better method, he extracts the CID blob from the developer edition aboot, and places it into the current aboot partition, then changes the CID to match the blob. This allows us to convert without needing to be on the developer edition aboot's increment version to unlock.
I have opted to not release the former method, as it could result in people who don't read thoroughly enough bricking due to flashing the old aboot on a newer increment.

Make that two of us, I am typically very thorough when I read instructions and have a way of thinking outside the box when looking at issues. Not to mention, if we can unlock the darn bootloader on these things, many of us could do a MM OS update from a more unbloated and pure form.

We should be able to change the CID on any Note 4 so I don't see why this wouldn't work. Don't we need root to copy the aboot? My understanding was that the kingroot method doesn't work anymore after an AT&T update. It is now soft bricking phones. I am wondering if the security update could be removed by flashing the original 5.1.1 or maybe even 5.0.1.

Unfortunatly, once you are on 5.1.1 you are stuck there. I believe that all attempts to roll back to 4.4.4 ended either in failure or a bricked device. To complicate matters more, after king root released I believe version 4.2 it became successful and unstable. Once the phone reboots automatically or manually, you cannot make it past the boot screen. You get a display that tells you to return to an att store. If you root now, you have to reboot via Odin to get the phone up and going again. With all that said, king root is stable to use, but only for a few minutes before unstability and then ultimately reboot. I always have faith in the possible and know that there is and will be a way around all this mess for a permanent unlock bootloader and root.

Unfortunatly, once you are on 5.1.1 you are stuck there. I believe that all attempts to roll back to 4.4.4 ended either in failure or a bricked device.

Yea, that's why I have been looking for the info that you were talking about. I want to see what I could do to help breath new life back into our phones.

[SM-T837V][Combo Firmware and Stock Firmware Files]

Hello Folks!
As soon as I got the tablet I spent a good few hours looking around for the combo firmware to start looking for exploits so figured I would provide you guys with a link to the firmware for free
It was quite funny actually, after I soft bricked and got stuck in a boot loop I realized I couldn't find any stock firmware anywhere either haha, so I spent a few hours looking for that as well.
I have the Verizon variant, I am not sure if it will work on other USA variants or not as I have no way of trying. With that being said, below will be the links. I will provide a rev1 combination firmware and a rev1 stock firmware as well as a link to a modified ODIN for easy flashing!
And with all that being said, the combo firm is good to bypass FRP. You can enable the oem unlock switch but other than removing FRP it is useless as of right now. You can however, mix and match the firmware unlike my S9+. I am currently on stock firmware with a permissive boot.img for example.
If you got questions or need help, well, you probably shouldn't be downloading anything or flashing haha. But I will try to help when I have time. I do not have any current plans to keep this thread going with updated filese as I had to pay for these. If I can find em free moving forward I will re-upload if I can but I typically stay on the lowest rev/firmware I can until I find a root method
T837VVRU1ARG4 COMBINATION FIRMWARE/FACTORY BINARY
T837VVRU1ARGG STOCK FIRMWARE
MODDED ODIN v3.13.1
If you feel like buying me a beer...​

What is the main benefit of this?

In the q&a section someone wrote it is readily rootable with Magisk. Is that not the case?

@elliwigy
Is there any firmware for the unlocked LTE snapdragon. I got the Verizon version but it's not playing nice with AT&T. Any ideas? Maybe flashing the unlocked firmware would help.

I think it's just the tablet, my Verizon one isn't playing nice with my Verizon service. Constantly not switch towers and losing service when full service is available. Or it's a tower problem but my note8 doesn't do it when my tablet does

Thanks for this, have been looking for a couple days for the build.prop file.

If you get permissive boot, try adb verity disable and mod through push pull adb style like we did on Att note 5

Will this work on sm-t817v?

I actually had a 817v. They called it the pro version. It was just an updated version at the time.

OEM Unlock
I have the T837V and would like to ODIN flash your files, but as you know there is no OEM unlock in the Developer Options on this tablet. Are you saying that you can flash these files without enabling the OEM unlocking?
I would like to install TWRP, but I believe this is not possible without enabling the OEM unlock. Do you know if this is true?
Thanks

there is no unlocking the bl so no twrp is possible..
you can however flash T837V/A/P/T/T1/R4/R7/W firmwares using modified odin

@elliwigy any idea what I could flash on a T835C without breaking Knox? Do you think I could flash a T835N or T835 no suffix ROM with modified Odin?

Forgive my apparent noobishness but what exactly will that do? Looking for a way to root and wanna know if u have found something I haven't.
Flash firm then what? Does it make OEM show or what? I just happen ta have the most difficult version of the tab S4 which is SM-T837V

I am currently working on a root method with the N9 but it should also work on Tab S4 once all is said and done. I actually found the exploit I use on the Tab S4 originally before I started workin the N9. Nothing is released yet as so far have only gained root on S9 Exynos and I am currently super bricked and waiting for a device replacement lol
Flashing other carrier firmware won't help you unlock any bootloaders or anything nor will it necessarily help you root. Only benefit I can see really in flashing other carrier firmware is say if you have an sim unlocked tablet (we'll say it's a Verizon tablet) and you want to use it on say Sprint. You can flash the Sprint software in ODIN and everything should work. It would be like you purchased the tablet from Sprint essentially.

I was wondering if i could flash firmware for my 837T for tobile to work on AT&T? I understand how to work odin etc, i just was not clear on the software variants and their capabilities.......
thanks
