Downloade Mode - Write Protection : Enable- safe flash with Odin?

I have Galaxy S4 i9505. I downloaded latest MEA firmware from sammobile I wanna update via odin. WHen I get into download mode. It says Write Protection : Enable. Will this effect from flashing via odin? Is it safe to flash? I have not rooted my phone, original stock rom doesn't give me the latest update of firmware. So I would like to update it myself. Even kies doesn't have it.
Please assist me. Thank you all.
I really don't want an expensive brick.

Yep just flash newest firmware whit odin
Sent from my GT-I9505 using xda premium

Mine said exactly the same... nothing to worry about, just flash as normal through Odin

I tried flashing CWM recovery instead. it says success but I still do not get CWM recovery. What did I do wrong?

for boot into CWM , you hold "power + volume up + home" after shutdown phone

I have a "GT-I9505". I was able to Odin TWRP. My objective is actually to turn it into an SGH-I337M, a bootloader unlocked version of SGH-I337, which is locked. All 3 are S4 variants. The mainboard of my SGH-I337M recently died. Since I couldn't find a replacement I337M board anywhere, and my research shows the mainboard of these 2 variants are interchangeable, hardware-wise, I bought an I9505 mainboard and dropped it in. An I9505 certainly comes with I9505's bootloader and baseband. Since I live in the U.S., I'd like to replace at least the baseband to North America, ie. my original I337M baseband. However, when I tried to Odin either the entire I337M stock ROM or just the baseband alone, it kept failing due to (AUTH). Since I was able to Odin TWRP, does it not imply the bootloader of my I9505 is unlocked? If it is unlocked, why is it preventing the baseband or the entire ROM from being flashed? I do have this "WRITE PROTECTION: Enable" message on my download mode screen too, but you guys have determined it can be ignored. Thank you in adv for any tips.

The I9505 is bootloader unlocked and comes that way by default; it's the US that loves locking bootloaders. Regardless, you CANNOT mix and match boards and basebands, as the low-level firmware in the S4 will detect the mismatch and reject the change. I know, as I attempted it with a flashable zip on my I9505. The device refused it and would not install it. Odin will reject it as well, for the same reason.
You would have to re-program the cellular radio's low level firmware to accept North American bands. People have tried it, including myself, but most of them were unsuccessful, including me. There is a thread in the forums here explaining what to do. Read it, and good luck.

I337 AT&T S4 - Return to Stock (No WiFi)

I recently bit off more than I could chew with my S4 (I337). I had 4.4.2 KitKat on it and wanted to root it to add teathering. I decided thought there was no root for 4.4.2 so I thought I would try downgrading to 4.3 then root. This seemed best because I didn't like the way the SD card is handled in 4.4.2 and some of my apps (like ftp server) have stopped working.
When I got the phone back up from flashing with Odin it says it has version 4.3. My WiFi will not turn on. If I slide the switch to on it slides right back to off and the phone tells me that an operation was block (can't remember the full verbage. I have installed and attempted to install many things on my phone. I have used recovery mode / Odin3 and Kies (Kies doesn't allow much).
At this point I just would like to get my phone back to 4.4.2 with the WiFi working. Then I can restore my backup and be back to square one with a lesson learned.
I have an I337 that currently thinks it has version 4.3 on it. The baseband version is I337UCUFNC1 currently. The build number is JSS15J.I337UCUEMK2.
If anyone can help I would greatly appreciate it. I have read and tried many things over a two day period and finally decided to ask for help.

Had this issue before on my Bell Canada S4, but don't recall exact way to fix it.
Think the solution was to find an older (might be newer) stock. I think I used a different version like the Telus Canada version as well and it ended up working. Then you update through kies after.

Wifi does not work because of the modem/kernel mismatch, i.e. MDB modem and MK2 kernel. Not sure what your goal was when you began flashing your phone but since you fortunately did not flash teh MK2 bootloader you are still able to locate the MDB full odin tar and flash back to stock which will resolve your issue.

It depends on what you are trying to accomplish. Are you trying to upgrade to MK2 or higher while maintaining your unlocked MDB bootloader?

If you don't care about losing your MDB unlocked bootloader you can get to the latest kitkat firmware by flashing the NB1 full odin tar from here:
http://forum.xda-developers.com/showthread.php?t=2674223, then once flashing is complete go to settings/more/about phone/software update then take the ota update to NC1 which is the latest kitkat version for our phone.
But what I would do is keep your unlocked MDB bootloader and since you already flashed the MK2 AP file you can get your phone running well again by flashing the MK2 modem: https://mega.co.nz/#!pwESna5I!YK7EKG37xXIG1ReB-Z-mfSMoXNkXQ9t2EdMK9ofgJKg
From there, there are still a number of options available to get to kitkat which I won't get into.

excited to give this a try. rooted with the downgrade method a couple months ago but left with a non-wifi device. my only issue is that the thread says it's for I337UCUFNC1 and our devices are on jss15j.i337ucuemk2. will this fix still work? I've heard on other threads on the subject that the modem kernel doesn't match up with the flashed rom or build number or something.

Do you already fix it??? cause i have the same problem

Same question, different thread!
Not even an hour ago did I answer the same question in a different thread: How do I get WiFi working on my S4?
Well here you go.
My original answer: http://forum.xda-developers.com/gal...-4-4-2-nb1-t2850878/post54978150#post54978150
The problem is, in order to get WiFi working, you need to install the NB1 modules, but to do that, you need to install Safestrap. However, you can not install Safestrap because the app keeps closing on you. There is a simple fix to this, which I will explain later. For now, just read this WHOLE post BEFORE you do anything, and keep in mind that I am NOT held liable if you mess up your phone. Use this at your own risk.
1.) Root your phone
If you're already rooted with something like SuperSU or Superuser, skip this. If not, read ahead. Download and install the Towelroot APK file attached to this post, open it, and click 'make it ra1n'. If your phone didn't reboot, now you have root (they need to trademark that). Now, down below, I also included the APK for SuperSU. Download and install it. Now open it. When you open it, let it install the 'Normal' way, not via the 'TWRP/CWM' way. Also, when it asks you to disable KNOX, say yes, wait a couple of minutes (it will still be loading) and reboot your phone. Open up SuperSU again, click 'Yes' to disable KNOX again, and now you have a good base to start from.
2.) Install Safestrap AFTER fixing the error
The error your are getting is easily fixed. Go to the Play Store and install 'SELinux Mode Changer'. Open it, grant it root access, and change the mode to 'Permissive'. Now, open up Safestrap again (you mentioned you already installed it), and it shouldn't force close. Click 'Install', and if the 'Reboot to Recovery' option below is not grayed out after that then it worked.
3.) Download and install the NB1 modules
On your phone, download the included NB1 modules ZIP file I attached for you, and once that is done you need to reboot. After the Galaxy S4 logo, you'll see a screen that says 'SAFESTRAP: DISABLED' and there will be a little robot. TIP: To enter Safestrap, press the menu button (physical, hardware key) under 'Recovery' at that screen. To continue to Android, press the back key (again, physical) under the 'System' tab. For now, press the menu button under 'Recovery'. Now, click 'Install' which should be in red, click 'Add zips', and navigate to your Downloads folder. Now click on the NB1 modules ZIP you just downloaded. Swipe to install, and reboot. This time, hit the back key under 'System'.
All done!
Now, Android should (and will) boot up, and you'll have working WiFi! If, for some odd reason, you don't have WiFi- do NOT panic! Just search around for the MF3 modules and flash those! All is good, all is good. A lot of this guide was taken from my post about my personal method of SIM unlocking the AT&T Galaxy S4 without the dialer codes or an AT&T SIM. It was just modified a little to work for you.
Remember, hit thanks!

Those are my exact words. Also, the attached files (NB1 modules, SuperSU, Towelroot, etc.) can be found attached to my post in the link above. Have a good night, and best of luck! :good::good::good:

can't boot phone

Hi, I started a thread needing help with my wifi but it has developed into not even being able to boot at all; it stops at the galaxy logo and either freezes or keeps booting. I have gone to the Odin page with all the different things to do and flashed the file to get back to the original rom but that is really where the trouble began. right now the only thing I can do with my phone is get into download mode, I can't even get into recovery. I have flashed a pit file that worked the first time but I don't know if that is part of the problem or not. Can someone please give me some directions, thanks
Also the phone won't boot at all unless hooked up to a power supply, the battery alone doesn't do anything.

More info is needed. What firmware / bootloader are you on? Was it rooted? Did you have a custom recovery installed? What version of ODIN are you using?

It is the AT&T s4. To be honest I don't know what firmware I am on, it is the one the Odin page said to use if you want to go back to stock. I never rooted it. The bootloader would be whatever the latest update was for this phone. I can't get into it to tell you anymore. I am using ODIN 10, the latest one. thanks

Well I finally got into recovery and did a factory reset, now it boots into the AT&T white splash screen before it just turns off. I am also wondering if my battery just died for some reason?

ODIN 10? Try using ODIN 3.09 and see if that helps. The latest update would be Android 4.4.4 NJ4 firmware. This link should help you, it will give you root with safe strap recovery though: http://forum.xda-developers.com/galaxy-s4-att/general/guide-odin-to-stock-updating-rooting-t2926642

Check out the link I posted in my last post. It should help you get your phone fixed.

I have been there. I went to the very last option which seems to be what I need unless I am missing something.

Neither odin 3.09 or 3.10 will even flash any file now. it either says invalid md5 or fails when it attempts it.

Well, I finally got it to boot into android but it is flaky at best. It is android 4.3 instead of 4.4 where it was initially. The wifi still doesn't work and now the keyboard keeps crashing everytime I do something. The build is jss15j1337ucuemk2 which I know is older than I had before. Does this give anyone a better idea of what I need to do? If I can get a stable flash then can I flash a modem file to fix the wifi? I really need some direction, thanks
Turns out the battery was completely drained which was causing some of the boot problems, I don't now how that happened but I am charging it now.

Well after using odin 3.8* I got it to install some older firmware ending in mk2 rather than the nc1 or nf4 that I had before the trouble. After I got it to boot, I went back into download mode and flashed the modem file and now everything works execpt I had to force stop Samsung keyboard and use swype. I would like to upgrade my firmware but since for a couple of more weeks it won't have a sim card I can't upgrade OTA. For some reason Kies says that firmware upgrade and initialization isn't supported with this model which makes no sense to me. It also says my firmware is up to date
Does anyone know how to flash to the latest firmware without me going through this nightmare again? thanks

I agree. But google has basically all he needs. More so rapidgator

I haven't found anything from Samsung to download. If I flash a newer build, do I also need to flash a modem file and a bootloader or can I just flash the PDA? thanks for explaining this to me.
And can I do a dirty flash so I don't have to lose everything again?

well, now I see that there is no sound. so I guess I will have to flash again.

There's. Something I'm yet to understand. Did you finally manage to boot into recovery? If so, flash a custom recovery (I recommend philz touch recovery) then use it to make complete wipe.
Then boot into download mode and flash latest pda firmware in the compressed file you downloaded. Ps: make sure it's from your region.
May be if you provided me with your region I'd get you all the files required

GT-i9505 S4 (Globe Telecom) Rooting and Flashing

No, it won't affect your network status nor be locked on your carrier. :good:

If the phone was neverlocked then flashing won't change anything.
But if the phone was locked and then unlocked at some point, it might lock it back.
It depends on the unlock type used. Some unlocks are permanent.
But if you bought it unlocked from the store/carrier, then there is nothing to worry about.

I was unsure of that though, might ask the previous owner for that thank you for the replies sirs. I'm trying to root the said S4 via odin by trying to flash the latest TWRP recovery via odin but the odin says
No Pit Partition
Removed
Added
Something like that, I tried 3 different USB cables and 3 Different computers already installed kies and reinstalled usb drivers in the process but still no luck.

Rooting can be done without the need of a custom recovery.
Did you un-tick re-partition in Odin before trying to flash?

Stock firmware can only be flashed with Odin.

the unit is from Globe and I have this annoying globe bootlogo at startup

UPDATE: Got to flash the custom recovery and use a custom rom Lollirom V9.0 the problem was the sync cable not sending enough current to the phone which causes the issues with the odin.
For those who have the same carrier and baseband, you can safely flash a custom recovery (CWM) and flash a custom ROM. It will be fine, networks still there even after I updated the modem to PA1. Goodluck

Repair malfunctioning Samsumg S4

I have a AT&T Samsung S4 that I would like to give to my daughter. Unfortunately, the S4 is out of whack. First, I keep receiving the message "The device has detected an application attempting to perform actions that are not permitted. These actions have been blocked. It is recommended that you restart your device." Second, Wi-Fi will not turn on. When I try to activate Wi-Fi from the pull down screen, it blinks green and then goes back to gray. Third, I cannot delete any of Knox apps. There is no option that allows me to delete the Know apps, just the option to force stop. Considering that I don't have cellular service (because the purpose of the S4 is just to use on Wi-Fi and download apps for my daughter), I can't really download apps without Wi-Fi.
Is there any way I can get my S4 to function properly again, such as reinstalling software? I'm not tech savvy, so I apologize. A lot of the threads I've come across only address one of the issues. Your assistance is greatly appreciated.

The wi-fi chip could be defective. I also have an i337 sitting in my desk that has no wifi.
You cannot delete knox apps without root.
Did you try a factory reset?

Yes, I did a factory reset. Is there a way to root the device without WiFi access? Given that I can't access WiFi, I can't access the Play store to download the apps I need to root.

You can root the device. But you need to be in stable condition first, like working everything fine and no system message popping up.
Could you tell me your android version, baseband, bootloader etc.. so that I can tell you the directions you need to take.

Look at this thread to get back to stock: http://forum.xda-developers.com/showthread.php?t=2616221

Android Version = 4.3
Baseband = I337UCUFNC1
Build No. = JSS15J.I337UCUEMK2
Kernel Version = 3.40-1921628
Secure Boot Status = Samsung
I hope this is helpful and thank you for your time and assistance with this matter.

You could try smartswitch or Kies to perform a factory restore. If that doesn't work, this thread may help: http://forum.xda-developers.com/showthread.php?t=2616221

It appears that your are on Jellybean 4.3 OS with Kit-kat NC1 modem.
You have several choices.
Like audit13 said you try smartswitch or Kies to perform a factory restore .
If that is not solved your problem you can flash the firmware via odin.
If you are not familiar with using odin this guide explain about the odin.
In that guide you will find the sections about how to get back to MK2 stock and links for the necessary files.
Once you were back on the MK2 stock see whether your wifi is working. If you want to stay on MK2 and root the phone you can use saferoot to root the phone. Here is the link for root.
You could also upgrade your android OS to NC1 Kitkat too. Then you could use Towel root to root the phone.

Thanks for all your help. Unfortunately, I tried the Odin method and during the process i received the Failed message in Odin. I suppose I'm SOL.

Can you post the screen shot of the odin message?

Did you try flashing the latest stock firmware from sammobile.com located here: http://www.sammobile.com/firmwares/database/SGH-I337/ ?

Here's the screenshot of the failed message.

If you download roms from sammobile.com, only unzip the file once and flash in ap.
Since it is stopping at the aboot.mbn file, either the rom you are flashing has an outdated bootloader or the rom is not for your phone.

How would I flash it? Odin?

Yes, ROMs from sammobile are flashed using Odin. Unzip the file once to yield a tar.md5 file. Then, this file is flashed in ap.

Yes I tried the latest stock firmware today and same problem...received Odin message "failed." Given that I cant seem to get back to stock via Odin, I'll probably trash the phone. Thanks for everyone's patience and help.

Dont' give up yet. You could install safestrap to get close to stock.

okay, so i follow safe strap instructions and bypass the odin steps in that thread? thanks for your help.

and just one last note...i cant even get passed the laoding screen. it is stuck so not sure safe strap will work if i cant download the app and get it the phone

What loading screen is it stuck at?
Maybe take it to a cell repair shop to see how much it would cost to force flash the firmware via jtag cable.
