Install stock rom on galaxy s3 through TWRP or dual boot - Galaxy S III Q&A, Help & Troubleshooting

I bought a used used phone rooted with slimbean on it. I did manage to update through TWRP and really like that rom so far. I'll present an app in a few days and want to use an mhl hdmi adapter to project the app on a screen. It seems there's a driver issue and slimrom wont ever support the adapter. So I need to install the stock firmware for the presentation and want switch back after and would like to keep twrp. I could also dual boot it and that would be even better, but does the stock rom supports it ?
Since I know how to use twrp, that would be the simplest way to install the stock rom, How can I do that ?
Is it possible to dualboot the stock firmware ? How can I do that ?
Thanks,
Kristian
EDIT: I have a SGH-I747m (canada) and don't know which stock rom I should use, I don't know the original carrier. I looked on sammobile but you need to know your carrier to find it's original rom.

Wrong forum, this is for the i9300 only.

YB-GB70/CW/XEG aka Samsung Galaxy S Wifi 5.0 DAB+

Hi guys,
I bought this device from a German online-shop. It's still on stock 2.3.6. Afaik this device is not rootable with superoneclick. I'd love to root it or flash a 4.+-rom, but do not know what roms and/or kernals are compatible. I do not even know if you consider this as a international or Korean device. It's 8GB and does have a physical home button. I use the DAB+-radio quite often and would absolutely not like to lose this option when flashing. Can anyone enlighten me on the options and pro/cons? Thanks in advance!

Go to the first link, follow the instructions there and if all goes well, you'll have a rooted Galaxy Player. Once done, you have to flash cm9 in your Galaxy player before upgrading to 4.3. Click the link, go to page 8, there's a step by step instruction that the ROM Dev wrote for someone who wants to go from 2.3.6 to 4++. And I'm not sure what's a DAB+ radio is but when I flash a custom ROM, the default radio is missing afterwards. Hope that helps.

Superoneclick does not work with firmwareversion 2.3.6. Losing digital radio is the main reason not to flash a firmware that doesn't support this. Is flashing a (rooted) kernal affecting usability?

[Q] complete noob but need answers xD

ok so i bought my international version galaxy s3 from ebay. it was already rooted and modified. i know cause i
cant receive updates. unless i use triangle away. obviously i still dont get updates because im on a custom rom which i have no idea what custom rom it is. rom manager doesnt tell me. rom manager says
that my custom rom isnt setup to recieve updates.
im on 4.1.2 JB. what im wanting to know is. can i flash straight to cyanogenmod 10.2 from my custom rom?
and will flashing to 10.2 keep me on 4.1.2 JB but with the cyan tweaks/mods or will it be 4.3?
also what is the best method to save my imei from any dramas. i also dont want to lose my network which ive seen people have this problem also.
is there anyway for me to find out what custom rom im using? i know that i have clockworkmod 6 installed.
im using 19300XXELLA on what i beleive is a custom kernel smp but cant be sure.
im sure this post has not made much sense but hope you can undersyand what km asking
i also looked at the sticky threads. they gave answers but i felt they werent the answers i needed specifically for me. except the imei question
First you can know your custom ROM most probably from about device info...
Second you can flash cm 10.2 or cm11 without any hassles with imei but if you want any Samsung based custom rom you should flash a newer modem... Search for them there are flashable zips available...
Before doing this,backup your efs by one of many apps on play store like ktool or samsung tool..
Cm10.2 means it is 4.3 android and cm11 will be 4.4.2..
And don't expect features of samsung firmware in those roms.. I mean better camera, swipe for screen shot and other features.. They are exclusive for samsung based roms...
For cm11 you must update your recovery to latest search for it flash then via Odin
Or cwm flashable zips are also available...

after all, i need to rooting the device to be more flexible

The device is already rooted, you just need to download any custom ROM you want, reboot to recovery, and flash your desired ROM from there.

first of all thanks for your answer.
If I understand properly
therefore, I'll have not any problem because of 4.4.4
that is correct ?
Yes, that is correct. The device is already rooted, with custom recovery, which means you can just reboot to recovery, wipe everything, and flash any desired ROM you want.
@@[email protected]........No disrespect intended, but this is "flashing 101" basics stuff........
The fact that you are asking it, tells me that you don't have the experience needed to do this comfortably.....
That's not a problem though.....we all start from the bottom, and learn as we go.....
But that being the case, i'd advise that you don't do anything to your phone until you've read, learnt and completely understood the processes behind the flashing procedure. It's best to understand what you are doing beforehand, rather than trying to figure out what went wrong afterwards.......

Rom Question. S6 Edge - SM g925Z Japan Softbank.

I Have the SM G925Z Version of the galaxy s6 Edge [Japan SoftBank]
I See many Roms that say "Works with many g925 Versions !" but the Japanese Z Version is never listed anywhere.
only the F T U V P etc etc versions.
If I use TWRP 2.8.6.0 to backup my current Rom, can I try these other Roms and safely return to my Stock Rom
if cell or wifi service stop working? If I try 5.1.1 Roms, I can not return to 5.0.2 roms?
Can I use TWRP to install a 5.1.1 rom that I download, even while my current Rom is 5.0.2 ?
or can I only install Roms using Odin Flash tool ?
My ZTE Warp phone was able to install Roms from downloaded Zip files with TWRP.
But I am not 100 % sure about the process.

First the s6 edge is a different style of device. To install 5.1.1 roms on the device you have to be on 5.1.1. Same with 5.0.2. Yes you can try any rom from the s6 and the s6 edge rom so long as you flash a special kernal for your device that makes the rom work on your device. If cellular data does not work, revert to your nandroid backup of your origonal os and flash another rom and you'll be good if that one works. Just repeat if the roms dont work or if you get tired of it then just stick with your stock rom which should be your nandroid backup.

Thank you. I can understand this, except for the kernal part, please explain.
How can I backup my current Kernal so that I can return to my Stock Rom backup.?
will a TWRP Nandroid backup do that automatically ?
how do I install the correct Kernal? with TWRP ?
for example, from the ROM installation , it says
[5]Install Zip from storage
[6]Flash The Capsule ROM
[7]Flash arter97 kernel
[8]Flash SuperSU
[9]Reboot
Im assuming 5 means, copy the rom to the phone, 6 means use TWRP to install,
so flash the kernal after the rom ? with Twrp ?
how can I backup my kernal first? so that I can return to my 5.0.2.
and last question, you said I need to be on 5.1.1 to try 5.1.1 roms.
the Japan SM g925Z is a 5.0.2 rom atm, they never updated to 5.1.
most of the roms I see are 5.1.1
Does that mean there is no way to upgrade to 5.1.1 while on 5.0.2 ?
or does that mean, if I flash a new TWRP and 5.1.1 Rom, I can just never return to 5.1.1 ?
Does TWRP Mean Kernel ?
maybe that is what I am missing.
I already have a working TWRP.
some roms do not mention flashing kernels in the installation, some do,
does that mean it does not matter? or does that mean that the installation guide is terrible and people are going to brick ---- if they dont know about it ?
Im not exactly sure the difference between kernel and Rom.
To answer your first question, the nandroid backup you do in twrp backs it up because it is a required portion of your rom. Which also answers your second question as yes.
The answer to your third question is you have to find a flashable zip of a custom kernal for your device. You can also try restoring your boot from the nandroid which contains the kernal and if that one doesnt work flash the custom kernal zip.
Next i need a link to the rom your trying to flash to check it out.
The only way to install 5.1.1 roms is to be on that android version. The reason is that android uses an sdk platform and 5.0.2 uses sdk 21 and 5.1.1 uses sdk 22 so those are incompatable with each other.
No way to update that device to 5.1.1 unless it is released for that device or unless the hardware sources are released for aosp roms which may be a while where samsung has not released them yet due to the new Exynos processor that they recently created.
No twrp is your recovery but it backs up your kernal with the backup.
Those roms are for specific device varients and will work without installing a kernal because the kernal that it needs is for the devices they are meant for.
The others that say install kernals are ones that didnt have the kernal put in the rom zip.

Either that or they didnt modify the kernals in the rom zip to the specifacations that they wanted so they fixed it and posted the kernal.
Sent from my SM-G925P using Tapatalk
thank you, that does explain alot.
I am not sure which Rom I should try. None of them actually say sm g95z.
Which roms would you recommend I try first?
I am not sure any will work, they all appear to be 5.1.1 only.
which means my 5.0.2 system can not test any of them.
or more specifically, if I upgrade to 5.1.1, and they fail to connect to wifi or cellular, then I can not return to 5.0.2 I guess.
Do you know of any that are 5.0.2 ?
those should be safe to try I guess.
I just want to get rid of the 500 retarded A-- Samsung apps that auto update.
I dont need Sfinder X_x, I dont need quick connect, I REALLY dont want virus protection from samsung clogging up my performance.
I have read about build.prop tweaks and updates, but the sm g925Z version did not get 5.1.1 updates, so those fixes do not work.
I do have Root access already, but with TWRP 2.8.6.0 (Because its said that it doesnt trip knox).
but I can not un-install these fkn bloatware apps, even with root access.
This appears to be a 5.0.2 Galaxy S6 Edge Rom.
http://forum.xda-developers.com/gal...edge-g925fxxu1aocv-v1-0-deodex-aroma-t3102974
but it says G925FXX, my phone is G925ZZ
I should be able to test it, and return to my g925ZZ TWRP backup pretty easily right ? since it is 5.0.2 ?
Just to confirm for other people.
I tested the VNRom 5.0.2 for G920F
it ran like S--T.
I used TWRP backup to go back to Stock 5.0.2 just fine.
no problems.

Hello, Have you found any compatible rom?

Samsung Galaxy Alpha (SM-G850L) Queries

Hi guys!
I recently bought a 2nd hand Galaxy Alpha Korean Variant (LG U+) here in the Philippines for about 130 USD. I have done several Google-ing and successfully rooted my device (after several attempts and soft-bricks). Unfortunately, I can't seem to find the compatible TWRP md5/tar file for my phone (have tried several files but no luck). May anybody provide me the right one? My device has a baseband version of G850LKLU2CPJ1 and currently running Android 5.0.2.
Secondly, can I flash an international stock ROM (e.g. the stock ROM of SM-G850F) to my device? Is this safe?
Another is that, I came across several posts mentioning that a 2500mAh battery is available for samsung galaxy alpha, will it be compatible with mine even if mine is a Korean Variant? And may anybody provide a site or shop where the extended battery may be available?
Fourth thing is that I am using an LTE sim card and I have known for a fact that 4G/LTE signals are available in my location. However, when I am using this phone, it only registers 3G connections. Are there any tweaks that I can do to use the LTE signals?
Lastly, may anybody recommend a good ROM compatible with my phone. I very much enjoy using cyanogenmod ROMS but haven't installed any because of my custom recovery problem.
Thank you very much and hoping for some positive responses.

Theres a TWRP 3.0 for korean variants made by serenityS. Do not attempt to flash ROM for G850F/M/W to your G850L it will soft brick your device. The only compatible ROMs are G850S/K/L. Its hard to find a 2500mah. You can use 4G switcher available on google playstore for switching different bands. There is no stable build for CM ROM yet, you could try the epsilROM for the mean time.

Of course you cannot flash a custom rom to the original/stock recovery manufacturers wont be liable for the damages to yoir phone due to incompatible of flashed ROMs.
1. You should root first.
2. Install custom recovery.
Galaxy Alpha (sltektt/SM-G850K). Galaxy Alpha ( sltelgt/SM-G850L). Galaxy Alpha (slteskt/SM-G850S).
Your phone variant is SLTELGT look for the thread of serenitys for TWRP 3.0 i havent tried the latest build of modpunk which 3.0.3
You can flash the above ROM jumbo alpha from twrp if you have a stock ROM. Its a debloated /system
