[Q] Several root attempts - will not move from stock recovery!

So
I have been struggling a couple of hours with this issue: Trying to root my samsung galaxy s4 i 9505, with three different odin versions (now last tried v.1.85) and both CWM and TWRP. I finally managed to get a pass from odin, but whenever I go into recovery mode on my phone, I am at the stock recovery "page", saying Android recovery on the top. Which must mean that I am not rooted.
I have no idea what to do, anyone there with some tricks up their sleeves?

Cheers for your reply, unfortunately I haven´t gotten longer than the first step. I try to flash stock rom, but it seems like i need a pit file and i cannot find a working one anywhere around the internet. Is there some way to find the pit file stored in my phone? Or another place where I can find a working pit file other than the one called CSB_signed_Fusion3_EUR_0325_V2?
Edit: Now I successfully reflashed stock rom and installed CWM recovery. Problem is that whenever I try to flash a rom I get the message "installation aborted".
What to do?

My phone is stuck in downloading mode after installing TWRP

Hi everyone,
Sorry to bother you with this. I recently purchased a Samsung Note 4 (less than a month ago). I successfully rooted it and it worked fine. But today I was incredibly stupid and I tried to install TWRP on my phone. I followed the instructions on this site (which I can't link because I am a new user) and tried to install TWRP using flashify. However, something went wrong and now when I reboot my phone it goes into downloading mode with a green android and text that says "Downloading.. Do not turn off target".
Now every time I reboot it goes into this. I googled this and I tried
1. to click cancel on the download
Does not work, goes to green android screen anyways
2. to go into recovery mode
Does not work, goes to green android screen anyways
I cannot perform a factory reset because I cannot go into recovery mode. I don't know what to do. Is there any software from the PC that would allow me to reset my phone? Of course it would be ideal if I can get it working without resetting it but at this time I just want the phone to work...
If I take my phone to someone, will they be able to fix it? Please help.

Download Odin and the TWRP .tar file.
In Odin, click the AP button and select the TWRP .tar file. Then just flash it that way and it should work just fine.
If that doesn't work, download a full stock ROM from either Sammobile or one of the mirrors here and flash it the same way using Odin. The stock ROM is probably a .tar.md5 file. Don't extract it further and just select this file in Odin.
You might have to install the Samsung USB drivers for Odin to work.

Thank you. If I knew I could have just flashed TWRP in with Odin earlier, I would not have gone through all the trouble. Unfortunately, the method I chose made my phone stuck in downloading mode.
I downloaded the stock ROM and used Odin to install it. I was able to get out of download mode that way but then my phone got stuck in an endless reboot loop. But at that point I was able to access recovery mode again so I just gave my phone a factory reset. It works again now. (Hooray!!)
If I every do try to flash TWRP in again, do you know which version I should use?

Just use the newest one on the official TWRP website.

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.

Really old modem and bootloader, what are my options from here?

It's been a while since I've flashed anything; at least a year, though more likely two. Whatever I have now I'm guessing is a rom called stock(ish)v06, since that's what is listed in my bootloader. I guess the modem (baseband?) is NAE, and I'm still using a very old version of TWRP (2.6.3 according to my signature, haven't checked).
Obviously, the development that still exists for this device has moved well past me. But given how temperamental my device has been lately, I want to give flashing something newer a shot before buying a new device.
Trouble is, I'm not sure how to go about flashing roms and finding the right modem/firmware when everything I have is so out of date.
Suggestions?

Download latest fully stock firmware so you will have latest bootloader and modem from http://www.sammobile.com
which is Lollipop, then flash latest TWRP. If you like stock, there is a stock deodex ROM, there is the awesome Wicked X (heavily modified Lollipop stock), or if stock is not your thing you can get CM12(Lollipop) or CM13 official(Marshmallow)

I want to make sure I understand what you're telling me to do, so a few clarifying questions:
1) I am meant to be updating TWRP first, then using it to flash stock firmware to update the bootloader and modem, and then flashing a rom of my choosing?
2) Why is that method preferable to using Odin to update the modem?
3) If I flash this newer official firmware, am I going to lose root?
4) In flashing the newer firmware, won't my bootloader lock, making it not possible to flash a new rom?

1) No, use Odin to flash full stock that you downloaded from sammobile.com, you cannot flash full stock from recovery.
2) Because some if not most newer ROMs require you to be on Lollipop bootloader.
3) Yes you will lose root, but this flashing of stock firmware is to update your bootloader and modem so you can flash the newest ROMs. The lack of root doesn't matter since you will be flashing latest TWRP via Odin and modified ROMs soon after.
4) if you have Sprint L720 the bootloader isn't locked. Check I'm 'about phone' to make sure you have an L720 and not another variant of S4
Make sure Samsung drivers are installed on your computer.
So your flashing steps go as follows:
1) Download everything you need first:
a) Full stock from http://www.sammobile.com to your computer
b) Latest TWRP tar file to your computer
c) The custom ROM of your choice (and correct gapps if AOSP or CM based) saved on external SD card on your phone since it will be flashed via recovery.
2) Turn phone off completely. I pull the battery then put it back in then boot directly to download mode: power + volume down. (Rebooting to download mode doesn't always allow a proper flashing)
3) Start Odin (uncheck reboot and reset time) and then plug phone into computer.
4) If COM lights up green in Odin click AP and select the file you downloaded from sammobile (it will be PDA instead of AP if you are using an older version of Odin) and click OK or start (I don't remember which it has)
5) If it flashes successfully pull the battery and then put it back in and turn the phone on normally. It will take a while to boot, like 15-20 minutes possibly. Flashing stock myself I have seen it say it was successful and it wasn't and the fix for me was to leave reset checked and let it do it's thing.
6) Once you have booted into your newly flashed stock OK3, do step 2 and 3 again, so you can flash TWRP.
7) When you go to flash TWRP in Odin uncheck reset time and DEFINITELY have reset unchecked (if Odin reboots your phone TWRP doesn't stick). Do step 4 again except this time select the TWRP tar file. Once it flashes successfully pull battery put it back in and boot directly to recovery (power + volume up) from there do a backup if you want, if not you can flash the custom ROM and gapps if necessary that you downloaded earlier.

[problem] sm-a700fd - cant flash rom

Hello,
I have a SM-A700FD. Some time ago I installed a ROM from xda (https://forum.xda-developers.com/samsung-a-series/development/rom-t3462703) The ROM ported from c7.
Now I am trying to go back to the stock ROM, but I just can not flash any rom.
Some reasons:
1. The PC doesn't recognize the phone (neither download mode, neither recovery, neither with a ROM). I tried in 4 different PCs;
2. I've got the recovery TWRP. I can flash the ROM, but the phone is stock in the boot screen.
3. Without the connection between the phone and the PC I just cant use the ODIN. Then I cannot flash again the stock ROM.
4. I had success flashing the CM 12.1 (UNNOFICIAL, but the ROM is old and full of bugs). Neither the resurrection rom, neither stock works on my phone.
5. The phone goes to download mode and recovery mode. My custom recovery is a TWRP 3.0.2-0.
Then I tried many ROMS (AOSP and stock, flashing by recovery) and all of them stops on boot logo.
Anyone got any suggestion?
Thanks.
Regards.

You need to wipe your data partition. AOSP/CM based roms and stock roms do not have compatible DATA partitions.

The rom I installed wasnt aosp. Made the wipe already... Nothing changes.

If you don't have a hardware problem then the procedure below should restore the device to a bootable state.
Wipe data
Install stock with odin
Wait at least 10 mins for boot to complete.

Well. Tried but, as I said, my pc (tried in até least 4 different PCs) doesnt recognize my cellphone.
Thats not hardware. It appeared just when I tried tô change the rom.

1- Load the following Samsung USB drivers for Windows:
http://samsungusbdriver.com/download/samsung-driver-v1-5-61-0
2- Install the drivers while you mobile is disconnected.
3- Put your mobile into download mode. (Vol Down + Power)
4- Run Odin and then connect your mobile after (It has to be recognized by assigning you a port number COMx in Odin under ID:COM).
5- Make sure that only F.Reset Time and Auto Reboot are checked under the ODIN Options tab (IMPORTANT: NOTHING ELSE IS CHECKED)
6- Select you Stock ROM in the AP tab of Odin and as soon as it is loaded hit Start.
7- The phone will restart and wait for few minutes till the Stock ROM builds its caches, optimizes its apps and start.
Hope this helps you restore your stock ROM and tell me how it went

Hi.
I made the procedure you said. First of all, Thanks.
The odin doesn't recognize the Phone.
The rom I installed in the first moment was Port from c7. I got that messages "warranty bit kernel" "Keynes is not seandroid".
Maybe something went wrong in that place.

Ok then it seems you have a bootloader problem. I suggest you unzip your A700FD stock ROM tar.md5 file by deleting the md5 extension (Rename SM-A700FD-ROM.tar.md5 to SM-FD700-ROM.tar), then unzip the ROM.tar file using WinRAR or 7Zip. Now you will have all the ROM partitions files including boot.img and system.img files as well as others. I suggest you place both files on your external SD Card via the PC (using a card reader) and then flash both from within TWRP (You can change in TWRP to flash img files instead of zip files) while formatting the data and cache partitions and reboot.
I believe that way you can restore the boot.img and system.img partitions, correct any corruption in the boot and system partitions and can flash the whole ROM again using ODIN or flash any other custom ROM (non ported) as soon as your mobile gets recognized by your PC.
Let me know how it went.. Good luck

Thanks a lot. I did not think in that way. I'll try and then ill post here if that worked. Thanks a lot.
