While Samsung has stopped updating the Samsung Galaxy Note 4 since Android 6.0.1 Marshmallow, you can still manually install your Note 4 to the latest Android 8.1 Oreo by installing a custom ROM if...
For those of you who want to root your Galaxy Note 4 or Note Edge on Android 5.1.1, you will need to flash a custom kernel on top of regular root method, otherwise you may end up in a bootloop. This is because Samsung has updated Android 5.1.1 with root block and the only way to get around it is to install custom kernel before installing SuperSU.
For those of you who need to unroot your Galaxy Note 4, perhaps because you need to return your phone for warranty, need to get out of a nasty bootloop, or simply tired of using custom ROMs and want to run stock, you can do so easily by re-installing the stock firmware.
Now, unrooting with stock firmware does not erase anything if you are coming from stock ROM or firmware, it will simply update you to the latest stock firmware you flash. However, if coming from custom ROM, you may need to do a factory reset. Doing a factory reset in stock recovery (after unrooting) WILL ERASE EVERYTHING on your phone. You may have to do that so if you are coming from custom ROM, BACKUP EVERYTHING on your phone before following the guide.
For those of you who want to root your Galaxy Note 4 and also install CWM or TWRP recovery at the same time (so you can backup, restore, and install ROMs), you can use the CWM/TWRP root method for rooting.
This root method works on all KitKat and Lollipop including Android 4.4.4, 5.0, 5.0.1, 5.0.2.
Resurrection Remix ROM for Galaxy Note 4 is now available in full Android 7.1.1 Nougat format to bring you the best and latest Android OS. If you are looking for a good AOSP(What is AOSP?) custom ROM that brings you stability of original Android with a ton of customization tweak options, you HAVE TO try the latest version of Resurrection Remix ROM.
I know many of you are probably running the Dr. Ketan ROM for your Galaxy Note 4 and while that ROM is an excellent ROM, it wasn’t a full S7 Edge Port and didn’t have Always On Screen working.
After struggling to root my recently bought Verizon Note 4, I’ve finally been able to root and unlock the bootloader after about 10 tries. It is pretty easy to do once you know how to do it but it took me about a week to get this working correctly, mostly due to the fact that temp root was hard to do with KingRoot and KingORoot.
For those of you who have been waiting for S7 Edge port on Note 4, definitely check out the latest version of Dr. Ketan ROM.
Originally developed for SM-N910G, Dr. Ketan’s ROM can easily be installed onto SM-N910F Note 4. You should also be able to install on T-Mobile or Canadian Note 4 with custom kernel and data fix (see the download link).
For those of you who want the latest Android 6.0.1 Marshmallow with root (based on official Samsung firmware not AOSP) on your T-Mobile SM-N910T, Canadian SM-N910W8, or international SM-N910F, you can do it by installing Dr. Ketan’s ROM.
Based on SM-N910G (which is the only model available with official Marshmallow on Note 4 models), Dr. Ketan’s ROM brings you the latest official Android 6.0.1 stock firmware to your Note 4 plus root and much more.
So, you want to try Android 6.0.1 Marshmallow on your T-Mobile or Canadian Galaxy Note 4?
Well, previously, many international ROMs were compatible with the T-Mobile models but starting with Android 6.0 Marshmallow, this has sadly come to an end. You can still install them but your SIM card will not be recognized.
Ready to take your Note 4’s performance to new heights? Then read on.
With Resurrection Remix ROM for the Galaxy Note 4, you can improve the performance of your phone by 20-30% over stock performance and almost reach the levels of Note 5. Although still behind Note 5, I was able to score near 70K on Antutu. And as you can see in the video, the Note 4 performs just as good or maybe even a bit better in the graphics department also resulting in higher 3D scores.
For those of you looking for early bird experience into the latest Android 6.0 Marshmallow on your Samsung Galaxy Note 4, you will probably have to wait until January or February. But if you have a rooted phone with TWRP recovery and a model that’s supported (such as the SM-N910F or SM-N910G), you can grab the unofficial CM13 ROM to enjoy Marshmallow today!
