Flashing a New Rom

I have an issue. I downloaded the ROM, ATT modules and Super SU. I made a mistake though. I extracted the files before I put them on my SD card. When I booted into Safestrap, I did the wipe but when you go to then select the ROM zip, it isn't there because the files are extracted. If I try and boot my phone back up to retry, I get stuck at Galaxy S4 screen. What do I need to do in order to try again? Thanks.

While the phone was in recovery mode, you could have used adb to push the ROM to the phone. Since you booted out of it, you cant. You need to start over by flashing the stock using Odin.

How do I flash to stock with Odin. I have only used Odin to change my Kernel version so I could use Towelroot. Which slot do I use in Odin and where to I get a stock NI1? Thanks.

Computer Comptent - Can I root and install a custom ROM?

Super simple...as a confident and tech savvy guy yet I have zero mobile modding experiance could I install stock andriod onto my note 4?
I already know about the hardswitch that cant be revsered the KNOX Counter, thats fine with me.
Is it something I could do or would it be hard to do...whats the basic process?
I can build and repair PCs and install OSes and trouble shoot common problems and all that marlarky...know my way around a BIOS ect.
As far as phones I have hard reset then vis there BIOS equivlent and cleared the cach but never more than that.

Rom has 5 parts, 1) main android os 2)Modem: it controls radios of your phone 3)bootloader: it supports booting up the phone, flashing *official* firmware , it will decide if a upgrade/downgrade is compatible basically works like BIOS but note that it will let you install only official versions of android signed by samsung, samsung official firmwares can be downloaded from website called sammobile, after you have downloaded a firmware in your pc it will be in the form of zip file, when you extract that file you will get a file in the form of .tar.md5 format if this file is extracted again then it will split up in parts like bootloader, recovery etc but you don't need to extract it again just flash the .tar.md5 file to Flash samsungs official firmware in order to do this you will have to enter bootloader's download mode on your phone this is done by turning off the phone then pressing volume down+power button+homekey on your phone the phone will boot into download mode will ask you to confirm firmware installation by pressing volume up key, *BUT* remember the downloaded firmware file is still in your pc so now to transfer and install it in your phone you will need a Pc software called "odin" just google "odin xda" and you will find download links, after installing and opening odin you will see it has 4 options BL, AP, CP,CSC (these are the rom parts i told you about you click BL and it will ask you to locate the bootloader you want to flash on your phone, click CSC it will ask you to locate the csc file you want to flash) but since we did not further extract our downloaded firmware we don't need to locate and flash these different parts manually if we just click "AP" and locate the downloaded .tar.md5 file it will automatically flash the whole firmware along with its bl,csc,cp and ap NOTE: First you have to put your phone in download mode then you have to connect it to your pc via cable and open Odin it will intimate you with a green box saying "connected " then you can go ahead and flash ur firmware 4)csc: this is country specific code, it enables/disables functions in the phone for eg the Samsung android firmware released in uk will hve its own csc and minor functions...and a firmware released in france will have its own csc and minor differences. 5) Recovery, this lets you clear cache, do factory reset etc in most samsung phones recovery can be accessed by shutting down phone and then pressing volume up+power button+home button at the same time and phone will boot into recovery mode. There is just an overview on how to flash different versions of "official samsung" firmwares on your phone before learning how to flash custom firmwares i suggest you learn how to flash stock firmwares first ( incase the custom os messes something up in your phone you will be able to get back to official software) There are many videos on youtube demonstrating how to flash official firmware via odin first watch a few videos on youtube before performing this.
NEXT: CUSTOM OS
Custom Roms like (stock android rom which is known as "cm" ) can not be flashed via Download mode which i talked about earlier in order to flash a custom rom you will need a custom recovery the official samsung recovery was limited to clearing caches, doing factory reset etc but these custom recoveries like TWRP, CWM have additional functionality which lets you flash custom roms (without entering and going through download mode) so in order to flash a custom rom you will have to download the custom recovery (i recommend twrp) for your phone's model from twrp.me (be careful install the one which is specific to your model or you could brick your phone) just download the recovery file in your pc, when you go to downloads section of twrp it will ask you to choose the format in which u want to download the recovery just download the one ending with .tar . Now to install this custom recovery in your phone, put your phone in download mode and connect with your pc and open odin, select "AP" option and locate the downloaded .tar recovery file and flash it. Now when you have flashed this recovery if you go to recovery mode (VOLUME UP + POWER + MENU while phone is off) you will see a different recovery than samsung's stock recovery.....this one will have many additional functions and options . At this point don't do anything just reboot your phone. Now that we have a custom recovery we can go ahead with downloading and flashing a custom rom to install a custom ROM follow the below instructions
> download the custom os u want to install (CM in your case) and place it in your phone's sd card, boot into recovery mode choose the option "install" it will ask you to locate the file, select the downloaded rom file and it will flash it. TADA...you will now have the custom rom running on your phone NOTE : again this is just an overview i suggest you watch videos on youtube and do alot more reading before doing this.

Very nice. I am in the same boat.
Coming from a Nexus 5 where we had android M and Flemental X which allowed for under volting and over clocking of both the CPU and GPU.
I want to root my 9100c which is on 5.1.1 but have some doubts about this complete Knox issue.
Still looking for good info on Knox. I dont care about my warranty. But what if Samsung releases an update say android M and it says you cant update because your knox is triped. ?
What are the best kernels for over clocking and under volting on the 9100c for the Nexus you could go with Franko or Elemental X on the stock Rom and you got everything you need.
Anything like that for the Note 4 ?.
Id like to keep the stock ROM, Root it and be able to under volt and over clock. Pls advise.

Huh this threads be merged or moved so not sure what happened to my reply but massive thanks for that explanation it helps a lot, I finally delved in today, its simpler than I thought but its also easy to make mistakes, I got a bit in over my head and almost bricked my note , and have learned it the hard way how to do some things, I thought there was only rom and root ^ and thats why I borked it mucking up kernels, and all sorts to the point I could only get into download menu, however now have a better understanding off it, and with a fellow member help I have restored my phone to stock, and will be installing CM13 from there.
Thanks again.

Galaxy S4 (GT-i9500) Major problem

Hello everyone. I used Albe95 N5+S6 Port rom for my GT-i9500 and it worked flawlessly. I had TWRP recovery. After a lot of using I thought to re-flash the rom and start using it new, so I reinstalled the Rom file on my external SD card and flashed the rom using TWRP recovery and it was a success, but then I noticed I accidentally backed up some things which I didn't wanted to I re-flashed the Rom again, but this time when I (in recovery mode) wiped the data, I chose "Advanced Wipe" or "Advanced Reset" (It was something like that I don't exactly remember. So after that I reflashed the rom and when I had to press "Reboot" a message appeared above saying "Looks like super user is not installed in your phone. Do you wish to install it?" I said Yes and the screen went blank. I tried to reboot but It didn't. I removed the battery and then put it back again and tried to get into recovvery but recovery seemed to be lost and I ended up in Samsung's own factory mode where we have options like reboot, flash using external sd card, flash using adb, enable cp logging and etc. I tried to flash back everything but nothing works. Tried Odin and tried flashing custom firmware but it fails. If I reboot Samsung Galaxy S4 GT-i9500 comes on screen and then it goes blank no boot animation or anything like that. Please help me, Your help will be highly appreciated

I used advanced wipe many times before, I'm pretty sure something else caused your dilema.
And most Odin fail messages are caused by the USB cable, PC USB ports (back ports are recommended) and Windows version.

So what should I do now?

If the problems are caused by the above mentioned, you should obviously try to change things up.

It appears that your phone is in soft-brick.
Also, you lost your TWRP.
Check your bootloader version and install the stock firmware via odin. (If you still fail in odin, As GDreaper pointed out, odin fail could cause by usb cable, port and windows version so you need to keep changing until it works)
Root the phone. Reinstall the TWRP.
Then flash the custom rom again. When you install the custom rom please follow the cooker (custom rom maker) instructions on wiping.

Thanks for your comment. I'm kind of a noob, how do I check bootloader version? and how will I know after checking my bootloader version which stock firmware to install?

Bootloader has nothing to do with it.
If you flash a stock firmware, the Bootloader will also be updated to whatever Bootloader the download firmware has.
The only situation where the Bootloader would matter is if you try to go from lollipop to kitkat, in which case it will fail.

Thank you. My device is back now.

I am glad to hear that your problem is solved.
When I was on kit-kat, I did not check my bootloader version and flash the stock firmware with older version of bootloader which tripped the knox counter on my i 9500. That was why I said to check the bootloader version before installing the stock firmware. You can use app like phone info to see the bootloader info. Then install the firmware with the same or newer bootloader.

I recomend to Update drivers, Windows, Bootloader install Samsung Kies and Install TWRP again, After stock

I messed up - No OS installed! (TWRP)

Hi all,
I had rooted my note 4 and have TWRP installed a while ago. Been using my phone for ages without installing custom ROMS, but recently it's been restarting every once in a while.
So I went into recovery mode and factory data reset my device to start fresh (of course backing up all my data with Tit Backup beforehand).
But me being the cleverclogs went into Wipe -> Advanced Wipe and selected all the boxes thinking it will do a proper cleanout (Dalvik/ART Cache, System, Data, Internal Storage, Cache, Micro SDCard). But when I try to reboot it there's a msg saying "No OS installed! Are you sure you wish to power off?". When restarting the phone it just goes back to TWRP!
It's on it's last legs already but still it's my main phone. How can I install the stock ROM or I might even try custom ROMS (any recommendations?). I haven't installed a custom ROM since the S3 days so I'm a complete noob agian.
Thanks for your help.

Copy a ROM on your MicroSD using a card reader and insert it on the phone or restore using Kies.

Ok thanks.
How do I use TWRP to install it?
Is there any links to Note 4 latest stock ROM (Marshmallow I believe).

You can try a Note 7 port,you can choose Racerom or Enhanced rom (if you have N910F model, for others models i don't know)...personally i have racerom v9 installed.
You just need to copy it to your internal memory flasht it, reboot to download mode and install the latest bootloader and modem with Odin, reboot and it's done....you need to search it for BL and modem here on XDA, it's not difficult.
If you choose to install a stock rom, remember you'll loose TWRP and root, everything it's replaced. Yo need to use Odin too.

Nothing to worry about bro. This forum will get your phone all set up and working.
At this point you have two choices
1. Flash stock samsung firmware (download the ***correct one*** according to you phone's model no from https://www.sammobile.com/firmwares/. Flash it using Odin. Look up the procedure to flash firmware on note 4 using Odin. Its pretty straightforward. (Make sure you do NOT select the PIT section. Dont ask what it is, just remember its the most risky section and could permanently brick your phone... It is marked properly in the Odin tool so the chances of mistakes are very low)
Note that after flashing a custom ROM you will lose your Root and TWRP. (You can get both back later anyways.)
2. Flash a custom rom using your existing TWRP recovery. If you have samsung note 4 android drivers installed on your pc, then as soon as you boot into TWRP, you can just connect the phone to the PC via a cable and access its internal storage from there. Download one of the countless good samsung note 4 roms (again, check your phone model before you download) from this forum. Copy it to internal storage. If needed, download OpenGApps package and copy it to the internal storage as well. Then using TWRP, *install* the Rom package. Remember, the Rom takes 7-10 minutes to boot up after install so dont worry. Also you phone might heat up in this while. If it gets too hot, then maybe something is wrong... remove the battery and let it cool down. Then figure out if you have the right rom or not. Else download another Rom.
Once you have access to the storage, you could choose to install any of the custom ROMS available
Remember, there are many variants of the note 4 sold across different geographical locations. Before you download any firmware/rom, be sure to check if it matches the phone you have. Read through the Rom threads carefully. if needed, ask questions.
You'll be up and running very soon.
All the best!

Sorry to answer your question with a question but why if you have twrp installed on your phone would you even mess with Titanium Backup?..also always keep a copy of a twrp backup on a extra SDCard of thumb drive...twrp in my opinion is the best thing available for backup and restore over Tit Backup or Samsung kias..spelled the wrong

Just so you know, you no longer have a titanium backup of your phone , unless you backed up online....
That went when you formatted the sd card so it will be a total restock.
In case you didn't realise...

Went to the website and downloading this one https://www.sammobile.com/firmwares/galaxy-note4/SM-N910F/VOD/download/N910FXXS1DQE5/169965/ (Seems my Note 4 is SM-N910F according to an earlier post I made). It's about 2 gigs.
Will follow the instructions at the bottom of that page to install it.

With Titanium Backup I was able to backup only certain apps, not sure if you can do it with TWRP.

I did copy my Tit backups to my PC before formatting it

I didnt take the time to read the post above but if you saved your backups on a PC I hope you're talking about your twrp back ups... if so transfer them onto an SD card put it in your phone and restore through team win you're good to go.... as far as a custom ROM for your phone as you probably already know all ROMs are just a preference no ROM is better than the other however my two favorite ROMs for this phone which I am back to lollipop would be Maximum Overdrive and the one I'm running now ...TEKXous hibrid n4... and I've basically installed every single custom ROM available for the T-Mobile Note 4 on marshmallow and on lollipop

Well after I downloaded the firmware and installed it with Odin following this guide:
Instructions
Extract (unzip) the firmware file
Download Odin v3.12.7
Extract Odin ZIP file
Open Odin v3.12.7
Reboot Phone in Download Mode (press and hold Home + Power + Volume Down buttons)
Connect phone and wait until you get a blue sign in Odin
Add the firmware file to AP / PDA
Make sure re-partition is NOT ticked
Click the start button, sit back and wait few minutes
I get this error in Odin:

Do you have the correct device drivers? They're needed in order to Odin recognize your phone.
Also, you need to delete the ".md5" extension, it only end in tar extension
Or you can try another Odin version...i'm using Odin 3.10.7

its realy realy hard to brick a samsung phone^^

might be the usb cable. also may need to get the pit file and try with a NAND ERASE ALL & repartition. BE SURE AND PUT THE PIT FILE ON CSC

So while I'm No Odin expert, I think that this Odin flashing process has many dependencies.
People have encountered wierd errors with Odin and they were resolved even when the person just chose to use an original Cable (or another) Cable.
samsung drivers are very very crucial. I think you may be able to find them by searching for Galaxy note 4 Odin drivers (they basically come with Kies I think but not sure)
also very important to have kies turned OFF while you're flashing through Odin
make sure you have at least 80percent or more battery when you flash.
theres also some other stuff you need to be careful of that you should look up on Google.
there's a thread on Odin flash troubleshooting on xda...icant remember the name but you should be able to just Google it.
also Google for the exact error message you seen on Odin.. remember there are bound to be other users who have seen the same issue... so you may be able to find a solution via google
And most importantly don't worry, you'll be good soon.
edit: As far as possible don't mess with the Pit files. they're very risky if you don't know what you're doing .

I googled the error msg looked like I needed a PIT file since the Note 4 is 32GB. I also used an earlier version of ODIN and redownloaded the firmware (not branded)...and after a few goes it worked!
I'm back on stock firmware.
Thanks everyone! :good:

Might have Bricked S7 Edge SM-935FD. Need Help to recover

Hello guys
My phone is Galaxy S7 Edge Duos- SM935FD. I seem to have bricked the device.
Below are the actions I have performed.
1. Flashed TWRP using ODIN as described on https://www.the***********.com/root-samsung-galaxy-s7-edge/
2. Booted successfully into the OS. Found superuser app installed.
3. When I went to back to Flash ROM i erased multiple things such as internal storage/dalvik/cache/system after which device got stuck in bootloop. Showing NO OS.
4. I tried flasing Custom ROM Zip files through OTG. The process failed showing package corrupt and still stuck in bootloop.
I can enter recovery/download mode however cant seem to get the device booted. How can I get the device to work either Custom or stock ROM.
I will be going through some threads in the meantime, your guidance is very much appreciated.

Flash stock rom with Odin: This shouldnt be posted on Development Forum but rayher questions and Answers.
Find what your Stock Firmware for your phone is using Sammobile and flash stock then re do rooting and TWRP Process

zzThrain is right -- I wouldn't risk flashing custom ROMs at this stage, especially because many contain new bootloaders or other stuff that might make this even worse for you. Just pick up the relevant Samsung stock ROM file (from, for example, SamMobile) and see if it boots normally again. Once it does, re-do the process *after checking all MD5s of the files you used* -- I, too, have had it happen before that a download went corrupted and I flashed it. If all is well, get into Download Mode and let Odin rip.

Go to recovery mode & transfer rom to phone using pc. wipe cache, delvikcache, data only. No need to wipe internal sd. Install rom & reboot.
if you phone goes to recovery or download mode, no need to worry. If it doesn't go to neither recovery nor download mode, them your phone might have probably bricked.

It's my pleasure to help you if you still facing this problem

Hi
I tried flashing stock rom from sammobile. I could find for SM-935FD hence downloaded SM-935F.
It got stuck at 90% showing System in ODIN.
From the ZIP file which is the file that needs to be flashed among below ? I tried AP.
AP_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship_meta.tar
BL_G935FXXU2DRB6_CL12365438_QB16944063_REV00_user_low_ship.tar

HOME_CSC_OJV_G935FOJV2DRAG_CL12785220_QB16560277_REV00_user_low_ship.tar
Now when I try again it immediately shows FAIL. Am i Flashing the right stock rom ?

It Worked. Thanks to all who helped.
I wasn't running ODIN as Admin and also was using an slightly older version V3.10.7.
