[Q] Custom Kernel - Sprint Samsung Galaxy S7 Questions & Answers

Just a question, I do not have this phone, but may want to get it.
I notice that we have root, which it seems like an engineering boot.img allowing for root ADB. (lame method but it works, prevents updates)
But, if we use root, paired with "dd", can we flash custom kernels or does the recovery/bootloader check this and cause it to stop?

No custom recovery or kernels with locked bl.

That is what I was assuming. Turds. Do we know what is checking for custom kernel or recovery? Is it bootloader? Is it looking for a sig hash? Maybe we could bypass it somehow through dissassembler and hex editing.

I'm not sure. Above my pay grade lol. But I do know that we cannot flash anything through Odin without it being originally signed by Samsung. I am unsure if Flashfire could install a modified Bootloader. But I am pretty sure somebody would have already tried that.

We can technically install anything using "dd" command from terminal. There's got to be a way.. lol. I really wish Samsung would stop this garbage. They are perfectly capable of making a fully locked down version for those who want it and an open version for those who want it (obviously open version would loose out on features).

Never heard of superboot, but you can try my guide here: http://forum.xda-developers.com/showpost.php?p=13762825&postcount=17
It's not a 'one-click' solution, but that's how I kept my root with 2.3.4.
Any way Not need to return FRG33?
Or some version of Froyo, no, as of now you HAVE to. When Gingerbreak works (if it ever does) for 2.3.4, it will be hard to miss.

flash custom recovery via adb, flash su from recovery, then reboot. The stock ROM will erase the custom recovery and replace it with a stock image. Your phone will be the same as it would be with superboot. Stock, rooted ROM with stock recovery.

Not quite, as superboot also replaces your boot image with an insecure boot image, which su does not.
Granted, but I highly doubt the OP really needs insecure boot given that he thinks downgrading is too much of a hassle. Without more info, I assume he just wants root in order run Titanium Backup , or Drocap, AdFree or some other market app that needs root to work for (what I also assume is) legit, non pirating reasons.
Just going from my own experiences, the easy one-click nature of superboot is a safe first step into modding and rooting for those afraid to brick their phone. I get the attraction and understand the reasoning, but you have to take the training wheels off eventually.
I was successful root nexus one...
And I use install-recovery.sh put app to ext(4G), And everything looks well...

Question - why? What do you want to root your phone for if not to use the wonderful tools of root. Why do you think fully rooting your phone will harm something. Locked or unlocked bootloader is not going to affect your phone. Rooted stock rom with recovery will not make it act funny.... Sorry not putting you out there but just asking why? Feel free to ignore me if you must...
Edit: Sorry to answer your question like the post above said you can root and then lock it right back up if that is your preference

I have come from an HTC Desire, which I rooted and had a custom rom (Cyganonmod) on and was very happy with it.
I am still not sure of what I would gain by doing the same with my Nexus 4 ?
any advice is much appreciated.
Is this new Cyganonmod installer the best way to go?

This phone is built for rooting and modding. You wont know what benefit you have until you either read up and see if the mods are ones you want or actually flash a rom. Sure try the CM installer but if you dont toolkits or just basic knowledge of android can get this phone roooted in minutes.
the CM rom on your HTC will give you the same benefits on your Nexus 4

I used a toolkit but honestly you can unlock manually by just booting into bootloader mode. Go into development and try Wugs Toolkit.... Rooting the phone is easy and all methods are relatively the same.
I do not see anything wrong with giving CM a try as well

I recommend you to stick to your original plan, its your phone, do what you like, you don't need to flash custom roms if you don't want to. I am using stock kernel and stock KitKat right now and the performance is excellent.
Follow these instructions to unlock bootloader, install latest kitkat factory image, install custom TWRP recovery, and root. http://forum.xda-developers.com/showthread.php?t=2010312
The links to fastboot package and driver required is in my signature.
Link to download factory image: https://developers.google.com/android/nexus/images
Link for latest TWRP: TWRP recovery
Link for latest SuperSU package: SuperSU package
After you do all that, in bootloader menu, you can flash back the stock recovery (recovery.img), which is location in the "image-occam-******.zip" of the factory image. (fastboot flash recovery recovery.img)
Then lock your bootloader by "fastboot oem lock". You can also use BootUnlocker to lock and unlock your bootloader on the fly while in the phone, without losing your data, since everytime you do fastboot oem unlock, it will wipe the entire device.
By using stock rom, stock recovery, stock kernel and temporarily unroot (SuperSU) or hide root (SuperSU paid version), it allows you to receive future OTA updates from Google. If you want to modify your phones more while staying with stock, read up on Xposed Framework and its module Gravity Box, which is not yet compatible with Android 4.4 but will be eventually.
Just remember if you don't have custom recovery, once something goes wrong and your phone can't boot, its very hard to save the data inside. Once you have custom recovery like TWRP, you can make a backup of your stock image (which also backup your stock kernel) and try out other custom roms and easily go back to stock, then you can flash stock recovery again to receive OTA updates.
Thanks for advice everyone.
I rooted and unlocked with Wugfresh over the weekend. A lot easier than I thought it would be

[Q] Attained root with TowelRoot, how to install custom recovery and ROM?

I've just been able to (finally) get root on my AT&T G900A Galaxy S5. (And I tipped TowelRoot, because this is awesome.)
I just tried installing a custom recovery with "dd," and Sammy's secure boot broke everything until I was able to restore the stock recovery via Odin. How can I install a custom recovery on this device? Is there a way to stop and deactivate Samsung's secure boot now that I have root?
I'm really looking to get started trying out Team Hydra's CM 11 implementation for the device, but first need a recovery and a way to bypass the secure boot feature on the device. How do I do that?
Yeah, this is going to suck to hear, but you can't. The G900A has a locked bootloader, which means the best you'll be able to do is use Safe Strap and other TouchWiz based roms only.
Just wait on hash code once he gets done we can put cm on I'm this phone lol
Sent from my SM-G900V using Tapatalk
I'm hearing mixed replies: one says that it's not possible, one says that it is.
Will we ever be able to flash custom recoveries and ROMs to the G900A?

If you have the AT&T S5 it has a locked boot loader which means sadly that you are not able to flash a custom recovery.
Ever? As in "permanently, no you will NEVER EVER EVER be able to flash a custom recovery?"

Understood. Sorry, I was just trying to clarify whether I should completely give up on the idea of possibly running CyanogenMod on my phone.
By the way, how does unlocking the bootloader work? Can they just dd the bootloader and brute-force it, or what's typically done?

Moto Z Play Rooting Guide

As usual, I am not responsible for any damages done to your device after trying this little guide.
1.-You need to unlock your bootloader first, which means this doesn't work on the Verizon variant. You also need to be sure you have your system image available in case something goes wrong.
2.-Then flash the chinese TWRP found here. Thanks to @hjk23 for providing the link.
3.- Flash SuperSU-v2.78-SYSTEMMODE.zip from here.
4.-BOOM, you're rooted. You need to have in mind that this is using the System mode and it works without modifying the boot.img. This means you will NOT be able to flash OTAs the usual way. I haven't tried using Flashfire since I have not received any OTAs so far.
If this didn't work you can also try flashing this modified boot.img, it has only been tested with the Mexican AT&T variant, so I don't know if it will work properly with other variants.
Thanks!
I would try this if I was certain Flashfire would work...(don't want to reflash for an OTA)

I take it back, sadly it is stuck at boot for me I tried it yes. No other SuperSu? I think I had the 03 version and you have 02... I think?
EDIT: not true, I had 02 too, but it just wouldn't work.
EDIT: It forced somewhat of a factory reset on me when I tried the same SuperSU but no systemless, I didn't lose any media but I had to relog in my account and download and update all apps again.
I will just wait for nougat...
several people commented that password is required to enter the recovery......

The same password that you used to encrypt the phone while setting it up. If you're using a pattern you can use the numbers equivalent to the pattern you used.

says it is not necessary to flash the .zip SuperSU only accept the root for the TWRP own. It is true?

Isn't there a warning to never accept the root from the recovery?
Another thing, if deencryption doesn't work you can sideload the SuperSU zip using adb through TWRP.

If you dont mind, could you provide the details of your device?
So I see there is a Chinese twrp for moto z play but is anyone working on a north American version? Same question for SuperSU? Will there be official versions with systemless root? I guess what I'm asking is should I wait a bit or go this route? I like otas. I also reeeeally like a rooted phone (exchange server BS needs to be bypassed for piece of mind).
Not enitrely sure what happened, but my phone wouldnt boot after flashing SuperSU, even after i restored stock system,boot, and EFS. The boot.img got me booting again though and now rooted. (US variant)
Edit: Can someone upload a stock boot.img for the US variant? I think my backup boot.img might be corrupt, as it causes my phone not to boot.

can't update to marshmallow

Hello friends
My phone is HTC One m8w
There isn't "update" in
Setting
About
Android version,
5.0.1
Software number
1.0.0.m8w
Build number
4.19.1402.15 CL458284 release-keys
Please help me for this problem
How can I update my phone?
Thanks a lot
Hello, I experienced something similar- complete absence of system update! A little digging revealed that any modifications to the system partition would render the device un-updateable, so naturally I downloaded the complete marshmallow package update for my device, booted into standard recovery, and updated from sd card
Hope this helps

if you are willing to, just root your phone and flash the marshmallow rom on to your phone and use titanium backup to backup everything before you do so.

You don't need root to install TWRP, nor to install a custom ROM.
Exception is Verizon, where you need root to s-off, and then unlock bootloader; as bootloader unlock by HTCDev.com is not supported for that version alone.

If you get bootloader unlocked, you basically rooted your device cause now you are allowed to modify the system data and make modification that can result in unusable phone. Plus if you are willing to take the risk of unlocking your bootloader, why don't you just root anyways, its just a matter of flashing super su zip.

No, you didn't. Root is a very specific thing. You either have root (SU) priviledge, or you don't. Unlocked bootloader does not give you root privilege. It only allows you to flash unsigned zips to certain partitions.

Think of it this way. If you flashed a cm ROM without root in the first place, you would get root. I'm not saying unlocking bootloader immediately give you root access but it allows almost anything that you flash to have root access

Some folks keep incorrectly stating that you need root to flash custom recovery on this device (on some devices, you do - but not this one). I'm just trying to make sure that misinformation doesn't keep getting conveyed (the post after yours said it, too).
Stating the process precisely, is the best way to do that.
