I'm currently using the Omega v10 ROM but I would like to go back to completely stock. I also flashed a new modem bc the wifi didn't work when I installed the custom ROM. How should I start? Should I use Triangle away first, reset the counter and after that flash the stock firmware? I'm using an UK unbranded GT-I9505 and downloading this stock firmware file for it:
United Kingdom BTU (July 2013)
PDA: I9505XXUBMGA
CSC: I9505OXXBMG3
Version 4.2.2
When should I flash the modem and where can I find it? Also, how can I go to download mode directly after reseting the counter?
Thanks :}
I usually have problems with the wifi after flashing myself, but heres how I do it:
1. Flash either stock or pre-rooted rom from the thread in xda. Doesn't matter if wifi isn't working here.
(1.5. Root the stock rom with cf-auto-root if it's not already).
2. Install triangle away, and use it.
3. After triangle away finishes up and gives you the option to go to download mode, do that.
4. Flash stock rom (or whatever rom you want), with auto reboot off.
5. Power down phone after its finished. Then power back up, and go into the recovery (it should be the stock recovery).
6. Do "Wipe data partition" then "Wipe cache partition" (phone will reboot after doing this one). You want to go directly to download mode again after the phone reboots.
7. Flash the modem, as "Phone" in odin, with auto reboot off.
8. Restart phone again into download mode, flash modem again with auto reboot off. Then start up phone as normally when flashing is done. Hopefully the wifi works after that.
It is long, and sometimes doesn't work but its my best method so far. Using triangle away seems to help it.
EDIT: Triangle away gives you the option to go straight to download mode after it finishes. Also there is a thread here on xda which has all the modems. If you are restoring to MGA, the Omega thread has the modem in the installation instructions I think.
Hi,
Modems are HERE

TESTED AND WORKING!
My phone previously was running TWRP with a custom ROM and kernel on MDL baseband. I wanted to switch ROM's anyway and didn't care about retaining information, so I was looking for the simplest thing to do without reverting to stock. Do the steps below and you can go from an MDL rom to an MF9 rom as well as MF9 kernel and modem in a matter of minutes.
1) Upload TriForceROM to your SD card. You can technically use any MF9 compatible ROM, but this is the one I used.
2) Boot in to TWRP and do a full wipe, then install TriForceROM. When the install is done DO NOT reboot the phone, you need to get it to shutdown completely and the only way to do this is to pull the battery. So pull the battery and turn the phone off completely.
3) Put battery back into phone and boot into Download Mode by holding VOL UP + POWER. Press VOL UP to get it ready to receive data. Plug your phone into the computer (if not already) and open Odin 3.07.
4) Proceed to flash the MF9 modem and other firmware updates as instructed in noobnl's post. You must follow the step to flash the bootloader as well.. it takes like 2 seconds to fix, don't forget it!
5) When Odin flash is done, reboot phone and let it load into TriForceROM for the first time and voila... everything is MF9 now.
When TriForce opens for the first time Android will say "finalizing update" and may reboot one more time (it did for me)... once you come back to the ROM you can look under about and it will say MF9.
Easiest firmware upgrade ever.
Ive been trying to upgrade my rooted I9505 to 4.3 without getting any of the knox bootloader.
I have installed I9505XXUEMK8-PRE-ROOTED-DeOdex-KNOXFree-SupeSlim-CWM.zip via TWRP but get really intermittent signal & data (no entry is on most the time).
I tried upgrading my modem via ODIN to I9505_XXUEMK8_MODEM.tar but after the reboot the modem is still MGA (tried several times once without the reboot option ticked)
I've also tried finding my CSC using *#1234# but every time it loads SuperSU and when i press back it just goes to Phone.
Any suggestions or past experiences welcome and greatly appreciated. I really wanna check out the hidden permissions control in 4.3

I have just done that but installed rom using Philz
Modem tar file must go into PHONE in Odin
Autoreboot must be unticked
Flash modem once
Reboot straight into download again
Flash modem again
Important modem must be flashed twice
That's worked thanks very muchly. Will now test for a few hours to make sure it solved the intermittent signal issue
to clarify for anyone else trying this:
1) boot to download mode
2) select modem as PHONE
3) untick auto-reboot
4) click start, wait for red text on phone to say END (ODIN will say RES OK!!)
5) hold power button to power off
6) boot straight back into Download mode
7) exit ODIN and reopen
8) follow steps 2 -> 5
9) boot back to android and check it worked
I followed the instructions in the thread that describes how to update to NAE from MF9 while keeping the MF9 bootloader: http://forum.xda-developers.com/showthread.php?t=2277480
I was on MF9 stock rooted (with TWRP recovery installed when I flashed the NAE modem via odin 3.0.7, not sure if that makes a difference).
All the steps seemed to go okay. As far as I can tell the versions look good. However, the device is super sluggish at times, especially the dialer. Sometimes I have trouble waking it. I can't toggle the WiFi on. I have not set the hotspot mod or sd card mod yet.
The device is essentially unusable. Every so often I will get a request to force close some app (like the dialer) because it is hanging.
I tried repeating the steps described in the thread above over and still get the same behavior. The second time I also did some more checking in the intermediary MK2 step after everything was set up and I did notice that sometimes it was doing the weird hanging problems there too (i.e. even before the NAE rom was installed).
I had no problems whatsoever with the device when it was on MF9.
Help! Any ideas??
Have you tried to install the nae modem. Its been observed that you need to install it in order to get full use of a NAE rom

Yes, that is the very first step in the instructions. For good measure I even went back and reinstalled the NAE modem (even though it appeared to be successful).
I am thinking maybe I should go back and try to install/downgrade back to the MF9 modem to see if that would help.
Update: Everything seems okay now. I went back and flashed the MK2 modem, then reinstalled the MK2 ROM, then the NAE modem, booted into MK2 to see that it was okay, then installed the NAE rom. So far so good :fingers-crossed:

You could flash a MF9 stock rooted zip. Or Odin MF9 tar.

I had the same exact problem and I found a way to fix that so I can run NAE.. I read someone post and I just did these step to have a perfect running NAE stock rom.
Steps How To Install NAE (Odex) properly with MF9 Bootloader
1. Back-up apps with Titanium Backup or MyBackup
2. Download the following tools and files to have on-hand
A. Odin 3.07
B. CF-Root
C. Philz Recovery [I used the latest one 6.41.6.tar.md5]
D. MF9.tar Official
E. MK2 Modem.tar (No Firmware)
F. Stock MK2 Odex ROM (No Bootloader)
G. NAE Modem.tar (No Firmeware)
H. Stock NAE.Odex Rom (No Bootloader)
I. SDCard Fix for NAE
J. Hotspot Mod NAE (Odex) [If you want Hotspot]
3. Put the following files on your External SDcard from Step 2 (E,G,H,I)
4. Start by opening up Odin 3.07, and flashing MF9.tar (Make sure everything is unchecked but Auto Reboot)
5. Once flashed let the phone boot up and skip all the steps of setting up your phone. Then check to see if your baseband and firmeware is on MF9. If thats all okay completely shut down your phone.
6. Go back to Download Mode and to Odin. Then flash CF-Root (Make sure everything is unchecked but Auto Reboot)
7. Once its booted shut down and back to Download Mode and to Odin then flash MK2 Modem.tar (Make Sure Everything Is Unchecked) Once that is done Hold the power button for 10 seconds.
8. Boot up and check your baseband and firmeware in About Phone. Once everything is okay shut down the phone.
9. Boot your phone into Philz Recovery Mode then find and Install Stock MK2 Rom
10. Boot up the phone and skip all the steps setting up your phone, Do the lockscreen fix shut down your phone.
11. Go back to Odin and Flash NAE.Modem tar file (Make sure everything is unchecked) Hold the power button for 10 seconds
12. Reboot into Philz Recovery Do the wipe to do a Clean Install of Rom
13. Install Stock NAE Rom then Boot Up
14. Shut down and go back to recovery and install the SDCard Fix and Hotspot then Reboot
Then you can get Triangle Away and wipe your counter clean.
This is what I did and it worked perfect several times without problems.
(Optional part if you want to reset custom ROM counter)
1. Odin flashed a full stock firmware (ROM and all) MF9 or below (I had MDL tar already so just used that)
2. CF-Root the installed rom.
3. Run Triangle Away to reset boot counter.
(Main part)
1. Odin flash TWRP recovery .tar and did a full wipe.
2. Odin flash Mf9 AIO .tar
3. Odin flash MK2 modem only .tar (NAE won't stick unless you do this first)
4. Odin flash NAE modem only .tar
5. Odin flash TWRP (You can use other recoveries for some other ROMS, but most NAE roms including Sacs Custom ROM and NAE stock rooted need TWRP to install properly or you get no cell. I haven't tried it on CWM, but know when I tried it wouldn't work on PhilZ Touch)
7. full data wipe using the recover for good measure (not necessary, it should be clear already)
6. Flash your ROM in recovery (I used stock rooted NAE)
8. Flash your add-ons, mobile hotspot, boot screen, kernel , etc. (I just flashed the odex mobile hotspot for NAE and a boot screen, left the kernel at stock because of a camera issue ktoonsez seemed to be presenting)
9. Reboot and enjoy.
(Note, only if using NAE stock rooted)
If your using the NAE stock rooted you will need and want to run and let the pre-installed supersu app disable Knox, then using an SE linux status changing app from the app store you will need to temporarily change your SE linux status. From there you can install the Xposed Framework and Wanam Xposed. In Wanam Xposed you can set the SE linux status so it wont reactivate after a reboot. Now you can uninstall the SE linux switcher you downloaded before. Next you can download an app that will do it, or manually fix the SD card write permissions. Finally using a root exploring file manager you can fix the permissions to make the lock screen work.

Thanks fir this. I flashed one modem than the next one right after and wifi fixed. Been working on this all day glad I found this thread

Hello everyone,
So I have flashed every GPE rom I can find and every time I get no signal upon reboot. I go into settings and search for a carrier and Rogers shows up I click it and boom I have connection, shortly after I go back to No Service again. I have tried flashing a modem but no result
I have tried these roms...
http://forum.xda-developers.com/showthread.php?p=52144457
http://forum.xda-developers.com/showthread.php?t=2343513
http://forum.xda-developers.com/showthread.php?t=2349077
All with CWM, Wipe, Flash, Reboot
I just don't know where to go with this... I was on Jellybean touchwiz before trying these kitkat roms, could it be that I have to upgrade to Kitkat touchwiz then to GPE?
Thanks all
EDIT!
To fix this problem do the following
1. Flash Modem with Auto-Reboot off, when it says "PASS" unplug battery
2. Flash Modem again
3. Reflash Rom(GPE in my case)
4. PROFIT!

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.
