Hi guys, I have read a bit about rooting and flashing custom roms for the GSIV but being my first time (on this phone) I thought it would be better to ask for some help from you experts ^_^
I would like to convert my GSIV as close as possible to a Google Edition one, in the sense that I don't want to have a super custom ultra cool rom, I just want a stock-like one, stock kernel, maybe a few extra features, root, nothing special...
Now, is it possible to do that without voiding warranty, or at least with the possibility to turn back the phone in a warranty covered state?
Could you point me to one simple guide to do so and maybe suggest a rom suited to my needs? It can get a bit confusing, there's too much complicated stuff for a newbie!
Thank you in advance!
Yes, it is possible to convert the i9505 (almost) completely to a Google Play device (though you will not receive OTA updates, so you'll have to download them yourself). It's fairly easy once you have a custom recovery installed.
Though, warranty might be an issue. In many countries, it will be void once you root and install a recovery, though this does vary. This also increments a "counter" in the device, so even if you restore it to its original state, it is still possible to see that you have at some point modified the software (although there are methods to root the device without incrementing the counter, not to mention that many have managed to claim warranty despite this). That said, this will again differ based on your country.
Now, if you're still up for it, there are several guides online which can tell you how to root and install a recovery on the phone. If you're running the stock 4.4.2 firmware from Samsung, then you can follow this guide to root:
samsungsfour.com/tutorials/root-samsung-galaxy-gt-i9505-s4-running-on-android-4-4-2-kitkat.html
Thereafter, you can install a custom recovery from
gadgetsacademy.com/install-cwm-twrp-recovery-on-galaxy-s4-lte-i9505/
(These are just two of the links which you get after a Google search)
Note that you don't really need root for this, just the custom recovery. Though, having root is a nice addition if you want to back up your apps using Titanium Backup.
Once that is done, you can download a Google Play based ROM from here on XDA, such as
http://forum.xda-developers.com/showthread.php?t=2557353
or
http://forum.xda-developers.com/showthread.php?t=2544474
Just reboot into recovery, wipe data, and select the zip file from your sd-card/internal storage.
Though, remember to backup your apps/data first.
Takenoko_, thank you so much for the detailed answer, it has been really helpful! One question, if I understood correctly, it is possible to install a custom recovery WITHOUT rooting, so if I did this and then flashed a rooted ROM I should have root in the end, right?
That's right. As you'll be using Odin, root should, at least in theory, not be needed to install a custom recovery. You can instead gain this by flashing a pre-rooted ROM
Great, all done! Thank you!
No problem
yes you can
just install custom recovery, (philz i like)
then flash dandvh rom
done
it comes rooted
----------
sorry i forgot
in some cases, you need to update modems by flashing
or just update your s4 to 4.4.2 then flash the gpe rom
I've been poking around the forums trying to figure out an answer to this, but nothing so far has worked. My question is a simple one:
How do I root a stock ROM of Android 5.0?
First, the tech stuff:
Device: SM-N900A / AT&T
Android: build LRX21V.n900AUCUEOC1
I had Android 4.4.3 (rooted with Towelroot), which I was finally able to force to upgrade to 4.4.4 by using ODIN to flash a firmware update. In the process, root access disappeared, but my overriding concern was to get Android 5. I found a stock ROM of it here, which I downloaded and which did install perfectly.
Now, I've tried a bunch of different things to get it rooted--including trying to flash the pre-rooted Android that Walter.White posted in another thread (my phone kicks back an "invalid signature" error when I try, the install always fails and what I get is a device that's like it's fresh out of the box)--I also tried the CF-Auto-Root route, with ODIN says fails and which causes my phone to freeze. Towelroot doesn't work, and I can't get Safestrap to work either (it complains that there is no root access and there's no Safestrap option in the restart dialogue box).
I know that I'm missing something, and I know that it's probably something absurdly simple. I've got no doubt someone else has cracked this, any chance someone out there could help me figure out what I'm getting wrong?
You must go back to android 4.4.3 and root like you once did, then flash the pre-rooted version android 5.0 and you're all set. Sounds like you have everything you need, just need to do it in the right order.
I rooted my wife's N9008V which was running Android 5.0 with Kingoroot and afterwards removed Kingoroot with Super-Sume. After that I installed SuperSu.
I know that I'm missing something, and I know that it's probably something absurdly simple.
very simple .
Op you are in the wrong forum this is NOT Note 3 AT&T forum .
I rooted my note 3 by flashing TWRP through odin then flashing the SuperSU.Zip package through TWRP
The n900a can't be flashed with twrp if it has a locked bootloader.
IT CAN BE DONE
Here's how I did it. (And don't blame me if you brick the phone, etc., etc....)
PLEASE DO NOT ATTEMPT IF YOU DO NOT UNDERSTAND THESE NOTES! Read them thoroughly!
1. Install stock NC2 (Instructions are all over)
2. Root with towelroot.
3. Install latest SU from the play store and update binary (you know the drill, right?)
4. See Chainfire's site here. http://forum.xda-developers.com/general/paid-software/flashfire-t3075433 Get FlashFire
5. Place the AT&T stock lollipop .tar file on your SD card. It is available in the note 3 forum.
6. Run FlashFire. Once it has done its thing, click on the + sign.
7. Click on flash firmware package and navigate to the stock .tar file.
8. FlashFire will analyze the file and you will see a screen with partitions checked. These are the partitions that FlashFire can write (AND ROOT)
9. Click the download sign at the top on the red bar.
10. Click on the check mark to Create New Archive (FlashFire will create a .tar.md5 file take note of where it is saved and COPY TO YOUR PC BEFORE you run FlashFire! You will need it!
11. Next you will see the screen with ACTIONS on a red bar. Scroll to the bottom and touch FLASH
12. FlashFire will now write the partitions that are checked. When it reboots the phone, IMMEDIATELY hold the volume down, home, and power button to enter download.
13. Go to your PC where you copied the archive (that .tar.md5 fike). Right click on the file and choose rename. Remove the .md5 from the file name or odin will likely give you an error.
14. Open odin and connect your phone. Place the .tar archive FlashFire created in the AP section and flash. It will write the partitions that FlashFire could not.
15. Reboot and enjoy rooted lollipop on your phone.
Hate that I still have to wipe data to get it to boot at all, but a minor gripe I suppose. Just hate having to reinstall my apps and set them back up. Thanks for sharing this, been waiting for something like this for a while!
Yeah but if you're already on rooted nc2, why not just flash the stock rooted lollipop rom?
Doesn't that process require using SafeStrap, where this process does not?

You can use flashfire...
Plus why go through all this hassle to reach the same result?
That's absolutely true. but think it is a matter of preference. I had some issues with Safestrap, but were it still supported for lollipop, I would probably still be there. I also had a soft brick when I attempted to do a backup, which supposedly still works by booting from the power screen. SO for those who would prefer a cleaner option, this might suit them better. Flashfire also has the potential to install other custom roms. I am still looking at that option.

this is the first post i've seen for the N900A that advised using Flashfire, all other posts required using Safestrap (which i personally did not like the idea of using just because it wasn't actually updating the OS on the phone, but essentially tricking the phone into loading a different set of files much like multi-booting). if it were possible to use Flashfire with the rooted lollipop roms, i'm surprised none of the thread OPs updated their posts to reflect that.
FlashFire has only been out since April. It is Chainfire's successor for Mobile Odin. It takes a while for all of the phones to be tested. There are a couple of other users that have tested it. Just search the FlashFire forum for Note 3 and you can read the comments. At least one other has used it on the AT&T variant.
reboot into download mode
I just finished your method successfully. Thank you. I would like to add that there was an option to reboot into download mode after flashing with FlashFire. I didn't have to worry
about immediately holding vol. down . I think the version of FlashFire I used is a little newer. Anyway thanks again!
I will keep trying
Hi all,
I was able to go through all the steps but keep getting stuck on step 14. Odin fails at the very very end and never finishes. I have done the whole process 3 times over.
Questions:
1. When picking the .tar in step 7, I am selecting the largest file of lollipop. I believe it is an AP file about 2.2 Gigabytes. This is the right one to select in step 7??
2. On step 10 when it ask you to Create New Archive, do i check ALL the boxes?? Nothing is checked by default when i press the download sign in step 9.
Other than these two things, everything else seems to work nicely. I did also notice that when Flash Fire runs and writes the system, wipe is set to OFF. I figured it was like that on purpose but just saying.
Thanks in advance,
John :good:
Sorry for the delay. I have moved on to the S6, so been busy with it.
For step 7, choose whichever ROM you wish to use. The one you have should be fine.
With regards to the second question, Flashfire should check the files in step 8 that are needed for the archive. Are you using a stock rom for step 7? If not, it might be able to flash without a separate tar file.
Ok,
Yes it was stock and thanks for the tip i will give this a shot as soon as i can and see how it goes.
So this will work to Root the Note III on Lollipop?
What exactly does Flashfire do in this case? Is it unlocking the bootlader, allowing for flashing a custom rom? Or is it only rooting Lollipop? I was looking at safestrap for running a custom rom on the AT&T Note 3, and someone mentioned in another thread that Flashfire was a better option for doing so, with no need for the multi-boot workaround. Thanks to anyone who can straighten me out on this, and if Flashfire doesn't allow for flashing a custom rom on the AT&T note 3, is there anything else out there that does?
I'm under the impression that the AT&T note 3 has a locked bootloader, which is my point of confusion.

Great Guide and find.
Flashfire has the power to bypass the security that would provent Odin from installing , for example a custom kernel, so be carefull with Flashfire, it installed a custom kernel on my phone and flagged Knox to a 1
Followed the steps in the 1st post...worked flawless! May I add its good to clear cache & delvic cache as well

Excellent. I don't like Safestrap, so this was perfect... I didn't have to wipe my phone, and everything went perfectly the first time. One note, I did have to put my phone in Download Mode (as stated in the OP) after the reboot from Flashfire. Thanks so much to all who worked on this!
Update: The OC2 update happened pretty much immediately after I booted. The OTA update actually managed to complete, and I still have root.
I am currently on 4.3 MI9 version..
i rooted it with chainfire method root de la vega.
Now can i flash NC2 with odin and continue the thing ?
Can someone point me to the stock lollipop tar? I cannot for the life of me find it in any of these forums. Please & thank you.

I recently picked up a Samsung SM-T280. The first thing I did was to come to XDA and see what modifications are possible. I haven't read everything but I've read a LOT trying to learn what the situation currently is as regards this device. A forum that tracks several different devices together (SM-T580, SM-T350, etc) makes this process a bit harder.
Ideally I'd like to unlock the bootloader, root the device, install TWRP then install a custom ROM. From what I've been able to gather:
- It appears to not be possible to unlock the bootloader of the SM-T280
- There are several methods to root the SM-T280 and then install TWRP
- There seem to be a couple of custom ROMs for the SM-T280, although I may be misreading this as I thought you couldn't install a custom ROM on a device with a locked bootloader.
Could someone who's followed the development of the SM-T280 far more closely than I give me a general sense of what's currently available for this device? I AM reading the threads in the forum and I AM trying to look these things up for myself. I just can't be sure that what I'm reading constitutes the best and most undated information.

It is a complicated and sad story. Lol. No there is root for device but it is Samsung and do not use bootloader to root. Little different with Sammy. There is an app for PC called Odin that directly flashes you rom if it's in tar format. . Md5 also works. Or you can use heimadal but I have no experience with this. @ashyx has a guide to rooting device and it worked perfect for me. I actually am without a PC at the moment and have had to flash. Img files to get back to kinda stock recently. Rom development is almost moot for our device although the 285 had a crap ton of stuff and our s had all the same insides from what I can tell even the ril files. They and phone. Sec have been blocked but if you expierement you may be able to get a working rom with the 285 files. I could be wrong though. I would just stick with the one available for 280 if you are not familiar with rom making (like myself). It is called tinker edition and is rooted with Xposed installed all beit a old version. But I thank that man everyday for that rom. Really makes a huge difference in usability. If I can help in any other way let me know good luck
That was incredibly helpful! Thanks for taking the time. I've used Odin many times so I'll likely start with Odin for root and TWRP. No unlocked bootloader is a shame but root is the thing I need most, as I imagine is true for most people. Thanks again.
Thanks. I was gathering info for rooting my device and most one-click roots don't work. I have the same model, the SM-T280. So Odin would work even with a locked bootloader? And will it wipe any data?

Sorry, I hope this isn't too late. Yes, odin will flash directly to the device. First you will get the .tar for twrp and flash it using the ap slot in odin. Make sure to be ready to hit the keys to go into recovery.(power vol+ and home) you have to get in to the twrp recovery to format data the very first boot otherwise the stock system will overwrite recovery and you have to flash it again.

Thanks!
Has there been any significant updates to this? It's hard to understand if custom rom was created or not since SM-T280 shows up in search along with SM-T285 and other A tablets.
So far I've been able to flash TWRP and install SuperSu, but I don't understand what to do from there. There is Tinker Edition out for the SM-T280 but I cannot for the life of me find out what that is and what it can do.
I'm on the fence whether to return this tablet after buying it on black friday for a more rootable tablet, or even a 7th Gen fire.

I managed to root it using the many guides on the site. Unfortunately I did return the tablet because there are no custom ROMs for the T280, and likely there won't be any.
i didn´t can install a new twrp and i m sooooo streesed D´x somebody knows how can do it? odin give me PASS and green, but when i try to open the twrp new open the same old twrp. when the odin finish, in the tab on mode download say.

Sorry to revive a dead thread, but you just have to hard reset so get out of download mode. I had the same problem. Just hold volume down and power button.
First of all, I want to tell you that I'm not very familiar with rooting but have just a bit experience flashing custom roms, so please go easy on me.
I have done some research and found a couple things that I couldn't find answers for:
1) First one is that apparently you need your bootloader unlocked/ OEM unlocking enabled in developer options, however since I upgraded to Oreo in last August, that option disappeared. I've tried two methods for making it appear that I've found online (keeping phone up for 7 days straight and reverting time back) but none worked. I've read somewhere that if you downgrade to Nougat, enable it then re update to Oreo your bootloader will remain unlocked. So, can someone confirm this? Can you downgrade with a locked bootloader? And if so, can someone guide me through it? (Additional question: will the downgrade reset user data?)
2) After unlocking bootloader you need to flash TWRP but I have so many questions on that. First: I couldn't find a TWRP for oreo. Does it work regardless of os version? Second: I found a guide from XDA that is written long ago, and it says "make a full backup of your system, including EFS before flashing". How do you backup without flashing it tho? All guides are about using either a custom recovery or rooted app.
3) Do you really need TWRP? I mean, can't you flash Magisk via Odin/ADB directly, perhaps without unlocking bootloader? What happens if I use install command from ADB?
4) So does tripping knox fuse achieve anything other than killing the nonexistent system updates and samsung guarantee? I want to make sure Samsung health is going to operate.
