I have a samsung galaxy trend s7392. Since it lags when playing high end games or using heavy apps, I'd like to overclock it. I have already rooted it. It has JB 4.1.2 as stock firmware with samsung touchwiz 4.0. Since it's not a popular model, the developers might not have developed anything yet for it. But since this phone's look, feel, features and stock firmware are a lot similar to more popular models like grand quattro i8552, i9082, etc some of you could know what roms and kernels would work good with it. Please help. I've googled my hands off. Thank you so much.

You might have better luck by going into the i8552 forum and ask a developer there if he knows if it is compatible. They would know the best.

Hi, I also own a Galaxy Trend S7392 and looking for a custom rom. But I couldn't find one. To start developing a new rom, I tried building from AOSP sources. The build was successful, but while flashing it on phone, ODIN reports FAIL as soon as it starts writing system.img. I am unable to figure that out why is it so.
I am looking for some concrete steps so as to compile a ROM for our phone and flash it from AOSP sources specifically. If you have any idea about that, please help.

After successfully building a rom you need to flash the rom from inside of recovery. I'm not sure of the specifics of your rom for flashing. You will need to go to your rom thread for that and read the guids on how to flash it correctly. You will also need a gapps package. goo.im has this. If you built for 4.3 aosp they have the gapps there. If you built for 4.4 you can try these gapps. http://forum.xda-developers.com/showthread.php?t=2397942

Thanks for the reply atrus5.
My phone is currently using STOCK ROM for my Galaxy Trend. There is no thread dedicated for Galaxy Trend Duos S7392 so there is a little information available at the moment.
I am stuck on flashing the AOSP generated system.img to my phone. GAPPS will come a lot later .

You have to flash the whole zip that gets built not just the system.img

OK, but I don't know how to generate the whole ZIP. Moreover,
ODIN requires .tar.md5 package to flash it. This is what I did :
1. Extract STOCK tar.md5 package
2. Replaced system.img with the one I compiled.
3. Repacked tar.md5 package.
4. Used ODIN to flash the tar.md5 package.
5. ODIN reported failed as soon as it started flashing system.img
Further help will be highly appreciated.

You will need to flash the rom from recovery.
First you will need to be rooted. If you don't have that you can find it here at this link. http://forum.xda-developers.com/showthread.php?t=2494471
You will need to have a cwm recovery. Here is the link to that. http://forum.xda-developers.com/showthread.php?t=2552935
Inside of cwm recovery you will need to factory reset/erase data, erase cache and dalvik.
Then flash the rom and gapps packages.
i don't know if your device is locked or not since I do not own this device. This is the best that I could find. I don't know if it works. This advice is for the i8552. Your best bet is to look through these threads to find what you are looking for. http://forum.xda-developers.com/grand-quattro

Lots of links to study.... Thanks
1) The phone is rooted. NO issues with that.
2) CWM recovery is not available for my phone. I tried the CWM recovery builder to build image, but the build failed. I tried to build the same manually, but on flashing, I get E:Failed to Verify Signature.
NO way ahead...

you can remove those bloatwares by just rooting and using root app delete to locate and delete. it will not only free rom but will also make your phone faster since the bloatwares that used to run in the background consuming cpu, battery and ram will have been removed.
Samsung galaxy trend s7392 folks use kingoapp from kingoapp.com to root your phone. it will surely root it. I've upgraded to galaxy i8552 quattro and the two phones are just a copycat of each other. so there are chances a custom rom intended for quattro(more popular of the two) could work on trend.

It's already rooted bro. I have done it on the very first day I bought the device. Still, not all bloatware can be removed by just rooting. So, I think there is a need of optimised ROM like CyanogenMod or any other.

Hey first of all, after rooting you will gain super user access and ofcourse after that you will be able to remove any system app(bloatware).
pls help i also have the same device
I have gt7392 pls help me to put any custom rom available if u get any solution pls share with me.
Thanks in advance
I am also an unhappy user of s7392. It is indeed a laggy phone and to be honest, root (vroot)+ removing any unused application, including play store, hangout and google+ didn't help it too much. Phone is still hanging, lagging and sometimes not showing who is calling or, worst, not ringing at all.
An optimised ROM it will be really grate.

Hello all,
I'm determined to get root for Lollipop. I've seen several other Samsung devices that, like ours, lost root in the 5.1.1 update. These devices also have twrp working and attempting to flash root results in a bootloop.
Based on what I can gather, modifying the kernel by setting selinux to permissive should do the trick in allowing root to be flashed safely.
I'm setting up a vm right now, so I'm going to attempt compiling an insecure kernel in my ubuntu vm.
If anyone would like to test, that'd be awesome! I actually haven't made the jump up, so I figure if anyone has and would like to test, I might as well ask and save me time in dl'ing the firmware and odin'ing up.
Thanks

I just made the update, but haven't gotten to twrp'ing it yet. Here's the kernel. You actually need to flash it via odin as a PDA. The kernel output is automatically a boot.img, which we can't really install. So i converted it into a .tar which we can flash through odin.
Edit: It just boots right into twrp for me, it won't boot system
Remember this is a test. If something terribly wrong goes happen, I'm not forcing you to test this: IT'S ON YOU.
That means that we need a flashable stock kernel as well. So we can flash SuperSu and right after the stock kernel and we should be fixed. In a way the same auto root does.
After flashing your kernel I couldn't boot into system. But I am able to flash TWRP with Odin and boot into TWRP. So I flashed SuperSU and wiped caches. I flashed back self made kernel.tar.md5. But still couldn't boot into system. Just flash whole thing again.
Now with the second try TWRP sticks and I was able to flash SuperSu and flashed my stock kernel back. But now I have bootloop after the startup sound. B.t.w. I used SuperSu 2.46
What's next?
If I remember right, bootloop after startup sound means some of the files in your ROM are corrupt...
The device loads in this order: Bootloader, Kernel, ROM. So if it won't boot at all, then the bootloader is corrupt. If it only boots to splash screen but not boot animation, then kernel is corrupt. If it bootloops at start animation then ROM is corrupt.
In other words, it's getting closer!
Edit: @andrewnelson23 Did you download the kernel from Samsung Opensource? If so I tried to edit their kernel following the changes here https://github.com/glewarne/S6-UniKernel/commit/4e3880c912ade3468f3f42189acb1d8d205901fb but it wouldn't compile for me...

It hits splash screen and will not go further. Actually this is the first time I've just done a kernel edit so forgive my incompetence.
Yes, I downloaded from Samsung source. The sprint note 4 had the same issue, and I believed the dev simply used a few menuconfig edits to disable selinux and root checking. First up, I need to build a kernel from their source to confirm that I'm actually doing it right. Then I will only try removing the selinux(with menuconfig). If that works I will attempt disabling the root check stuff. If it doesn't work, I'll undo the selinux stuff, disable root check and see if that boots. We'll see.

An option that might work is KingRoot
Once you are rooted you can use Super-Sume to remove the KingRoot apps and replace them with SuperSU
Kongo Root doesn't work. I have already tried.

Of course we can get your started but see
But first you must answer us these question three.
Why do you want root?
Do you have a computer? (This is a must for root.)
Are you ready to be disappointed?
https://forum.xda-developers.com/tmobile-s7-edge/how-to/how-to-root-s7-edge-t3410470
follow this (use odin to flash rooted kernel) ......you should search before posting things like this.....google is your friend bro.
GOOD LUCK - BTW use flash fire app in play store to make backups and flash roms
Okay okay.
A quick glance at T-Mobile Samsung Galaxy S7 Edge Guides, News, & Discussion would have led you to the "How to root the S7 EDGE" thread.
I'd take a look in there if I were you.

Well while I was waiting I just rooted it. So what do you think that would be the next step towards installing a rom? To answer your survey questions :laugh: :
1- Because a phone without being rooted is like a bird without wins.
2- I do
3- Oh well... tell me more

EDIT: I just checked and the root didn't go through... even though ODIN said it was successful

Well then.
Rooting the phone (as I'm sure you had already found out) was fairly easy.
BUT... since we do not have an unlocked bootloader then we cannot have any custom recovery. Which means we can only (for now) use adb and Fireflash to flash any custom firmwares. And while we're on the subject of that... there is only one custom rom. Well... technically there are two but only one for you since you updated to the latest firmware.
Echoe ROM which was updated (ummm...) September 9th (not including the Verizon version which might work but with no promises)
Tekxv2 which was updated back in July. Unfortunately, that is flashed by adb (computer required) and only supports G935TUVS3APD8 which is... pretty old.
Things that you may notice with root.
Battery life may be shorter.
Strange icons on your status bar.
Might start to have random reboots for absolutely no reason.
Can't use Samsung Pay and some other apps.
Phone might be laggy.
Phone might feel hot.
Some of those can be resolved by flashing the only custom rom that we have (Echoe ROM... which is a rather nice rom) but it's not "there" yet.
Or you can use the guide in my signature to resolve issues like the lag and the strange icons. Yet even after the "fix" you might still experience both again from time to time.
You might even have the IMS force close issue which I used to get about once a month. It would piss me off because no sooner that you click the button, it'll pop up again and you don't have time to do anything. You're pretty much forced to reflash stock, wipe, re-root, restore a latest backup... which can take hours and is rather inconvenient if it happens to you while you're at work like it always seemed to happen for me.
SO...
All in all... root is okay. It's better than nothing I suppose. But until we get more developer support for this phone then in my opinion it's kinda pointless in my opinion.
Too many drawbacks. I eventually unrooted two weeks ago and I love my phone now. I'm using the heck out of Samsung Pay especially since their promotions are pretty nice right now! Plus a few members are testing the Nouget update which probably won't be getting root at all since rooting requires an engineering kernel which we don't have and might not get. Or an unlocked bootloader which we've pretty much given up on.
A lot of members that are testing the Nouget beta firmware are extremely satisfied with it so if we can't root Nouget then having a rooted S7 will probably fade away as more people update to Android 7+. That's where I see this going anyway.

So for what I understood the dev support for this phone is very limited... I know the issues I may encounter, I had them with the galaxy note. but any way... If something I'll unroot it but I want to try it out Thank for you time. I've rooted it.
EDIT: Damn... I really don't like the visual style of Echoe... is that one the only one I can flash??
Binary100100 said:
Well then.
Rooting the phone (as I'm sure you had already found out) was fairly easy.
BUT... since we do not have an unlocked bootloader then we cannot have any custom recovery. Which means we can only (for now) use adb and Fireflash to flash any custom firmwares. And while we're on the subject of that... there is only one custom rom. Well... technically there are two but only one for you since you updated to the latest firmware.
Echoe ROM which was updated (ummm...) September 9th (not including the Verizon version which might work but with no promises)
Tekxv2 which was updated back in July. Unfortunately, that is flashed by adb (computer required) and only supports G935TUVS3APD8 which is... pretty old.
Things that you may notice with root.
Battery life may be shorter.
Strange icons on your status bar.
Might start to have random reboots for absolutely no reason.
Can't use Samsung Pay and some other apps.
Phone might be laggy.
Phone might feel hot.
Some of those can be resolved by flashing the only custom rom that we have (Echoe ROM... which is a rather nice rom) but it's not "there" yet.
Or you can use the guide in my signature to resolve issues like the lag and the strange icons. Yet even after the "fix" you might still experience both again from time to time.
You might even have the IMS force close issue which I used to get about once a month. It would piss me off because no sooner that you click the button, it'll pop up again and you don't have time to do anything. You're pretty much forced to reflash stock, wipe, re-root, restore a latest backup... which can take hours and is rather inconvenient if it happens to you while you're at work like it always seemed to happen for me.
SO...

How are you doing with the ads? Like youtube, pandora, spotify? I just installed xposed and the phone feels very hot, and If I unroot it (which I'm thinking to do) I won't be able to get things without ads (I know about vpns and browsers). Also how can I install teaks for apps? Installing apks from pages that promise you this and you have to log in is very untruthful. Any suggestions to all this?

I just put up with them.
In all reality, I don't use my phone for the purposes that require my viewing of ads to begin with.
Sure when I was rooted I had adblocker. But honestly, I had completely forgotten all about that benefit of being rooted until now.
I suppose if you absolutely need to be rid of ads then by all means, retain root. However ads don't effect my daily use one bit.

I just flash the appropriate firmware that you had prior to rooting with ODIN.
Never had any issues. Which "guide" are you referring to?

You're probably trying to flash a firmware with a V3 bootloader over G935TTMB4APK1.
If you were seriously following that (outdated) guide step by step then you tried flashing TMB_G935TUVU3APG1.zip over a PK1 firmware. Yeah... that doesn't work.
Download the latest firmware from sammmobile.
https://www.sammobile.com/firmwares/database/SM-G935T/
Try it again.
IF that doesn't work... try using Smart Switch.
I haven't done it before but I think it's the Emergency Software Recovery and Initialization.

You have no idea the help you gave me. I went to sammobil before but since it said that the download speed was too slow, I didn't do it through that page. Now I did it and it's working fine thanks bro.
But when I start it, it says: custom in the log in, how can I totally put it original?

You should flash everything.
BL= Bootloader (which should be V4 since you updated to the latest firmware already. Anything less than V4 will fail.)
AP= Is for System, Cache, kernel, etc.
CP= Is for modems
CSC is for your HOME_CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 file.
Important! If you use the CSC_TMB_G935TTMB4APK1_CL9507190_QB11413830_REV02_user_low_ship_MULTI_CERT.tar.md5 (doesn't have the word "HOME" in the name) then it'll wipe your phone!
If your phone still says "CUSTOM" on it then make sure that reboot and check again. If it still says custom then make sure that you don't still have the engineering kernel. Re-flash the AP files again if so. It shouldn't though if it's 100% stock. Also note if you saw the unlocked padlock on the S7 Edge splash screen (before the bootanimation).
Good luck and happy New Year.

This is great but is there a way to uninstall it (if necessary) and get back to the primary ROM (stock or Lineage OS) without losing data?
tried to do a bit of light research and couldn't find what's different between this and other preexisting multiboot solutions. I've been using Dual Boot Patcher for sometime without issues. Is this somehow better? and if so, how?

EFIDroid is what you would call a "second-stage bootloader". The main advantage over Dual Boot Patcher (at least for me) is that you no longer have to patch zip files before installing. Also, EFIDroid is more than just a multi-boot solution. Quoting @m11kkaa:
efidroid tries to focus on simplicity, and doesn't require any kernel modifications etc.
in general: well having such a powerful bootloader in your boot stage gives you lots of possibilities, like multiboot, replacements/additions for kernels/ramdisk/cmdline.
This project has a lot more potential than what's currently implemented. i.e. you can give samsung devices fastboot and sony devices a standalone recovery. Also you can natively boot GNU GRUB if you're into booting linux kernel's the desktop way.

The two solutions are similar enough that you can migrate your setup from Dual Boot Patcher to EFIDroid without losing any data. I'll try to post a guide later this week.
I was I under the impression dual boot required multiple ROMs running the same kernel... If that is the case a huge advantage efi has is each ROM having their own boot img. I'm currently running 3 ROMs a lollipop a marshmallow and of course a nougat. I really just wanted to see all 3 latest android os running flawlessly on 1 device. And I did just that hats off to the developer for this.

There's an uninstall button in the app. Or, you could just flash the original boot.img via TWRP (basically what the uninstall button does).

Thanks for bringing us this tool. One thing I can't figure out...how do we Odin a different bootloader? I have DOK2 loaded now, and want to put Dr. Ketan's on the phone. The sub instructions say to Odin the BL and CP, as the ROM is generally generic. There us also a datafix and an essential fix that needs to be applied. Doing all of that is easy, but how do I keep two separate bootloaders (LP and MM) totally separate? If I flash a LP over a MM, my camera breaks, and if I flash a MM over LP, WiFi breaks. And I'm not talking about dirty flashes, a full system, data, and cache wipe 3x. Only Odin back to the base ROM keeps my phone happy.

There's no way to have two different bootloaders. EFIDroid comes between the bootloader and the boot.img, so it has no control over the bootloader.
EDIT: EFIDroid may be able to emulate the behavior of another bootloader... you would have to ask @m11kkaa for details...

I will have to look into it... The EFIDroid app error messages are not exactly the most helpful kind. (Good thing the app is being phased out soon). That particular error message could mean many things, but most likely it's a connection issue. We will continue this in Slack.
Will this work on tw 7.0 if i was porting a rom. Also why wont aosp kernel work on tw.. i always thought tw was aosp with skin..
Go to back to the link posted above where you got the unofficial apk and go to post #83. The OP posted an apk there that works fine on our phone.

Tried what you suggested but it didn't work either. So, I chose the 'nuclear option': I wiped the phone completely then reinstalled the stock Marshmallow ROM. using Odin. After that i installed TWRP v3.0.2 (trltetmo) and Supersu v2.79 as well as Busybox v1.26. Only then was I able to install EFIDroid successfully. Now, I'm able to boot the stock rom as well as Resurrection Remix.
It seems that if your going to install EFIDroid you must have the phone rooted using SuperSU. Using Magisk to root your phone instead of SuperSu won't work (at least it didn't work in my case).

This should work anywhere, regardless of ROM... But btw, it's a stretch to say TW is just a skin on top of AOSP. In fact, TW is probably the farthest you can get from AOSP... There's a lot of significant differences that make AOSP kernels incompatible with TW ROMs...
On Custom Oreo ROMs/kernels such Renovate ICE O, Batman ROM, Nox Kernel, notorious kernel , Wifi does not work on my S8 G950F. The only way to make these work up to now, was to restore the boot image from stock rom.
Whilst restoring stock boot.img does resolve the issue, it creates another in that after reboot wifi takes about 2 mins to turn on.
This Solution Worked for me, but doesn't always work for everyone, try it:

the stock boot is one you would take from twrp, or if you don't have that can install soldier rom, skip all the install options, then just backup boot in twrp

I take it the 2 files trick didn't work for you? So are you facing the issue of really slow WiFi start-up after reboot? Glad your here anyway. The more people we get the more chance a dev or devs will take notice
Still dealing with this in 2020. I'm using a Japanese S8+ with stock Oreo firmware and a custom kernel, the second I flash Magisk and my boot image gets replaced, WiFi breaks. I checked the file directory mentioned in post 174 and I see both files are present on my phone, unless the files @noxxious posted are modified in some way.
