There are a few reasons why can't some people out there just go and install a custom ROM, here are a few:
1. You are not rooted
This should be clear, you have to have root, I can't even see a way of installing a custom ROM without root. You can search for a guide on XDA Devs to help you.
2. You flashed your ROM the wrong way
Even though there are a few ways of flashing a ROM, only some of them are correct. You can't use Flashify for a ROM, trust me you'll only get into trouble. You can't and you should not try to flash a ROM through Odin, remember, Odin is only used to flash Stock ROMS, yes, you can maybe flash a ROM trought Odin if you knew how to convert your ROM to system images and then pack it up to a .tar.md5 file.
3. Your ROM zip may be corrupted
Double check if your ROM zip is the right size and check if you can open it via WinRAR or 7Zip.
4. You flashed a ROM for a wrong model
With Samsung devices, there will be the F, the I, the A and all the others. If you have an F and flash a ROM for an A, your device will not work. Also, some people don't see the 5 in SM-G925 although they have a G920, so their ROM will work fine, but the touch sides will be inverted.
5. Your proccessor isn't compatibile
I don't know if this is true, but my friend now lives in America, so he has a Galaxy S6 Snapdragon model and I have a Exynos model. This could be a potential problem, but I don't really think.

hello..
i need a cutom rom for galaxy s5 g900h but it must be (.tar.md5) to flash with odin not by intalling from recovery mod...pleaaaaaaase..thanks
usually tar file is a firmware... you can easily find a customed recovery,don't contradict it.
You can't install custom ROMs via Odin, it doesn't work that way, only stock ROMs work with Odin, just install a recovery and flash the ROM, not that difficult. Google is always there to help.
I need rom for lntex slice 2
You can't do that, sorry. Just go through with it on recovery.
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.
Hi guys, I need just a little help, I am the new owner of a Samsung Galaxy S7 Edge, but not new to XDA or flashing ROM's rooting devices, s-off'ing phones etc, but only on HTC's.
I know that before you change anything alwayS know how to fix it first, so.....so far I have downloaded all of the following to be what I believe to be for my phone:
G935FXXU1BPH6_G935FVIR1BPH2_VIR.zip ROM ZIP with contains 5 files (im with Virgin mobile in the UK)
Samsung Drivers for windows (already installed)
Odin 3.11.2 (didnt need anything like this for doing HTC's)
I already have fastboot and ADB from working on my HTC.
Now the phone is an SM-G935F Exynos Octa 8890 chip and when I check for updates comes up with 3 sets of digits of whats already installed, G935FXXU1BPH6/ G935FVIR1BPH2/ G935FXXU1BPH1
So all I want to know, is if I flash a custom rom for my device, and TWRP etc, will that come with 5 files too or do I just flash it in the AP section of ODIN ? also if anything goes wrong and I need to flash the stock rom back again, do I just flash the whole zip in the AP section, or do I extract the zip and just flash the AP part, or do I need to flash all parts, AP, CSC, BL etc ?
There is also something I read somewhere, I think it was at Sammobile, about before flashing a rom you must set a pin and also modify some kind of meta data, extract the zip, modify and then zip back up ? sometimes there are just too many guides and they just lead to confusion.
They are both snapdragon 800 device,but 9508v is the China mobile 4g version(with unlock boot loader).How can I use 9506 ROMs for 9508v?If I simply flash it should end in bootlooping or no signal or no lte connection?What can I do to let it work perfectly?
You don't. Odin will refuse to install a ROM not meant for the device, even if the ROM you're using is from Samsung. So there's no way to put an I9506 ROM on the I9508. Your only alternative is a custom ROM.
Oops it's my fault,I didn't describe it clearly?
Actually what I mean is a custom rom(flashable zip in recovery),how about that?
One more thing,it's i9508v rather than i9508?
A custom ROM should work, but you likely will encounter issues with the kernel. If there is a custom kernel for your device you'll need to flash it after flashing the ROM. Otherwise the device won't work correctly, if at all.

ok, I have a question about the i9508v, I couldn't find a custom rom or recovery, if, say, the i9506 has a custom rom and recovery, it will work with the corresponding ones, won't there be a boot loop or a brick?
@predator1222 Kudos. You actually used the search engine to find a relevant thread! Most don't.
To answer your question, the recovery includes the drivers for the hardware as part of its makeup. This is why there is no generic recovery that works for all devices. So, while you could install the 9506 recovery, chances are good you'll not be able to use it.
You would have a similar issue with the ROM itself, as the kernel and binaries are designed for a specific device. It would bootloop, though Odin should allow you to recover by installing a stock ROM.
and if I try to flash the factory ROM to the i9506 with Odin? would odin load it or throw an error or would it end in a boot loop?
I have issues with my current ROM, and need to flash a new one.
My firmware is the L31C432B411 however there seem to be three .zip files out there.
A update.zip, a update_full_VNS-L31_hw_eu.zip and a update_data_full_public.zip.
Back when I used to flash Roms in my Galaxy S3 there were only ever one .zip I needed to flash so I'm a bit confused.

Hi Pman96,
yes those firmwares ( FULL OTA MF ) include three files you must use all.
If you cannot use Firmware Finder to directly update, then exist a couple of methods ( similar to themselves )
like HWOTA or HuRU that can do the trick. Both methods requires your bootloader should be unlocked
and install a custom recovery.
You have single sim model so choose B413 or latest B415, just in case...
Best regards
