[Q] Firmware upgrade encountered an issue

It looks like I got myself in a pickle. I have a GS4 running 4.2.2. I picked up my phone today and successfully rooted it with instructions from DroidView using files from chainfire. I then installed CWM recovery with ROM Manager and backed up my ROM with it. I decided to replace chainfires SU with the one fom CWM like I had on my S3. After rebooting from recovery mode I noticed I had lost root so I used the same method to root it again because I thought it had reset itself. Before the reboot occurred there was option to prevent the possibility of the ROM flashing itself to stock. I went to select the Yes option but bumped the power button which selected No. While trying to reroot and failing, the phone displayed the message "Invalid percent of drawing download progress bar." On reboot the error “Firmware upgrade encountered an issue“ along with a cone and a couple of other pics. I have tried to get into recovery mode several times but repeatedly get this error. I can get into download mode and have tried to flash the stock ROM for this phone but it fails in Odin 3.0.7. Odin sees my phone and verifies the md5 but fails very quickly upon clicking start. I tried this with KiesPDLR running in the background and disabled. I have not tried anything else out of concern for messing it up further. Attached are screenshots and log from ODIN along with the text that is being displayed in download mode. (I will have to post these later as the attachments option will not work properly on my wife's S3).
Two other notes. 1) I used ODIN 1.85 to root as that was what was included in the chainfire download. But I used ODIN 3.0.7 to try and unroot because that's what the DroidView directions said. Would it make any difference to use ODIN 1.85 to try and flash the stock firmware? It sees my phone as well but the F. Reset Time option is unchecked and grayed out and the directions says it needs to be checked. Don't know if that really makes a difference. 2) My phone is actually with US cellular but there is not a forum for this carrier. I chose this forum because my previous phone the Mesmerize had an identical model number as the Fascinate. Please do not pass over my request for help because of this as I am in dire need.

Try odin 1.85 I use that to odin back to stock and dont worry about the other ones just make sure auto reboot is checked.
Also are you sure the phone you have is the sprint gs4 sph l720 jfltespr?? Cause odin a tar file not for the phone could potentially brick the phone.

I would try to download the stock rom from a different source if you can. These tar files are so large for this phone that the possibility of a bad download is pretty high. Also, make sure you don't have to extract the actual .tar file first from the archive you download. Lots of these stock roms are repackaged into a zip file and you need to extract the tar file for use in Odin before installing.

I am back in business. I have my phone and home internet back now. Yeah. I used the same stock ROM I had since it was the same as sammobile which was also a zip file and I already had it on my system. I just used Odin 1.85 instead. I guess I could have done this earlier and prevented a near stoke but everything else I had done seemed to get me deeper in a hole. These large zip files have always made me a bit nervous but I haven't found where to get one otherwise.
I have some follow up questions.
1) Why would it flash with Odin 1.85 and not with 3.0.7?
2) Is CWM's SU not compatible with the S4? Everything was working fine until I switched this from chainfire to CWM using ROM Manager.
3) Is there a good source with unzipped ROM's?

Chainfires SuperSU is much better with JellyBean than cwm SU. For some reason most people that try to switch to SU from SuperSU have the same problem you had.

Okay. I decided to go with chainfires after this fun little ordeal. The few small things I preferred from CWM is not worth it. Besides it looks like chainfire made some upgrades since I last looked at it. I guess I was lucky with my S3 because I converted several times.
Thanks for all the help everyone.

[Q] Odin Keeps Failing

Hello. I have been searching for hours like a mad man on Google for a solution to my problem, but i'm having no luck. Excuse the nooby nature of this post please. So I rooted my Galaxy S4 and I am trying to get it back to stock by flashing the AT&T md5 onto my phone (Galaxy S4 SGH-I337) through ODIN and it fails every single time. Initially, with ODIN 3.07, it would return something like fail (auth). Then I tried with ODIN 1.85, but that version returns "Complete(Write) operation failed." In addition, I attempted Kies but it too failed (no specific error code), and now the phone wont boot. It says that the firmware upgrade encountered an issue. I am not able to access stock recovery or TWRP because it will automatically go to Download Mode with "Could not do normal boot" in the top left corner if I in any way attempt to access it. I am using the stock cable with USB Debugging enabled. I also tried two different computers, two different cables (one being stock of course), and tried every single usb port on both computers. What went wrong? I will give you my upmost respect if you can solve this. I also am absolutely willing to supply any information you may need. Just ask. (Please don't be bricked. Please don't be bricked)
-With kind regards, Branden.

Let me guess you had the att mf3 firmware and tried retoring by flashing the MDL firmware via odin? You said md5 so I assume mdl? You might at this point still be able to fix it visiting a best buy near you if it has a samsung center. Also att store can reflash mf3.

Click Here throw this thread in the MF3 pile... guys we got another noob here, take a trip to your closest best buy and hope the samsung experience will flash the mf3 update for u

You mention md5, which as febby assumed I'll assume to be mdl, and twrp. Do you have mdl firmware on your phone and did you have twrp installed. Assuming you had twrp you were probably on mdl firmware. If so, I would re-download the firmware and try again. It would help if you could explain where Odin is failing too.

I never actually got TWRP working. I flashed it through Goo Manger and I was never able access it (It went to download mode with "Could not do normal boot" in the corner). Does this change the type of firmware I was on? In both cases of ODIN, the newer version (3.07) fails immediately after you start the process at around NAND Write start. It returns Fail (auth). In the older version (1.8.5), it reports that the write operation failed. I attached screenshots of both cases.

If you never got twrp to work then I'm almost positive you have mf3 firmware. You're best bet is best buy and have them re-flash the firmware.

There is no way to fix your problem currently so like jd1639 said, take it to best buy to the Samsung Experience area and tell them Samsung Kies firmware update fail and it did this to your phone. Thats what I did yesterday, they flashed it and I have my phone working again.

And just so everyone knows...md5 is part of the package name I believe... (.tar.md5) or could be referring to md5 checksum...anyways as was mentioned and you acknowledged, best buy is your best bet

Yeah it is the dreaded one! Root your device and flash a custom ROM or use titanium backup to freeze the update apps.

[Q] Failed root with odin, cannot detect with Kies 3

I recently got a Galaxy Note 3 from Verizon. I wanted to root the device, it was really easy with my old original galaxy so I looked at a few guides which were all using "Root de la Vega" and finally tonight in an attempt to root my device I used the guide at:
phonearena.com/news/How-to-Root-the-Verizon-Samsung-Galaxy-Note-3_id48247
I put the phone into download mode and connected it to Odin with the included Samsung USB 3.0 cable. I selected the root de la vega firmware using the AP button and hit Start to begin flashing. Almost immediately after the write starts it fails and on the phone it says:
"Secure check failed: cache"
Click to expand...
Click to collapse
In the guide it mentions there may be problems using the USB 3.0 cable so I tried it with a USB 2.0 cable with the same results. I tried rebooting the phone to see if it had wiped it. Indeed, it had been wiped and is now going to the screen which says there was a problem updating the firmware and says to use the Software Recovery Assistant to restore the firmware.
I am not sure why this has happened. I feel like I followed the instructions to the letter. After looking at some different guides I am noticing that many have you put the phone into USB debugging mode which the guide I was following doesn't mention. Is this why it has failed. Is this strictly required?
I would like to get this device rooted, but now my number one priority is getting it back into a state where it will be more useful than the paperweight on my desk. I tried downloading Kies 3 which I read can restore the stock firmware on the phone. I was extremely annoyed when I realized that Kies 3 would not recognize my phone at all. It says that the device is not supported by Kies 3 and gives me a link to check support (which just brings me to the Kies download page which clearly states that my phone (Note 3) is supported. I even tried to download the original Kies software which will not even recognize the device enough to tell me it's not supported.
Can anyone point me to a way to restore my phone to factory settings? Can I download the stock firmware and flash it with Odin, will this work if I couldn't get the custom firmware to flash in Odin (possibly because of not setting USB debugging?).
EDIT: Note that, following the guide, I did not check which build number my phone is before running Odin, now I have no idea which it is and what stock firmware to download. Is there anyway to figure out which build my phone was on or which stock firmware I need to download?
EDIT: So it looks like my problem is similar to this problem posted on XDA. I followed the link in that thread to this guide to restore the stock firmware. However, it has three different downloads for different builds, I am not sure which I should download or if there is a way to figure it out. Will any of them work? Can I try them one at a time safely until one of them works. I don't want to mess things up any worse than I already have.. I downloaded the MI9 firmware from that page, but this is just a guess... Anyone have any idea?
Any help will be very much appreciated.

Click the link in my sig and d/l the MJE tar, flash it in ODIN (instructions also provided)
Then, you can follow the root, safestrap and cust rom links...
All links, step by steps, everything you need to get you up and running are in the link in my sig
Start fresh with the OEM MJE tar, then go from there... Hit me up in that thread for additional help!

Thank you very much! I wish I would have found your guide first. I flashed the MJE firmware, was able to successfully root using Kingo (after a few attempts). I also installed safestrap and the open source superuser app.
Now I just have to figure out what roms I want, looks like I can take advantage of the multiple rom slots and try a few before installing one into the stock rom slot.
Again, many thanks!

Odin to MJE Question
Hi, my phone is fully stock with MJE on it. To root my phone, would I need to install the MJE tar file and also use King or just the MJE file? So far, I have had no luck using Kingo to root my phone.
Thanks

Just Kingo should do it for you. I did this last week stock on mje. Make sure you have usb debugging enabled or it won't work. I also used Kingo 1.1.6 instead of 1.1.7 and I had no problem at all woth knox or anything. It worked like a charm.

I used 1.1.6 because I wasn't sure if their new version was going to automatically add a custom recovery and trip Knox. I was reading the comments on their facebook page (Kingoapp) and saw one that said it will trip knox but a few days later read that it was a option to install a custom recovery. Instead of taking a chance I downloaded the older one and used that. Also in the 1.1.7 comments there is a link to official Samsung drivers if you want to be sure to have the latest ones. There are links for all their versions on the fb page if anyone wants to try that route.

Rooting w/Kingo
Finally was able to get root! What I did was uninstall the Samsung drivers and re-install them. Thank goodness it's finished. I also just installed HyperDrive and Beans. It's kinda nice having a choice each time I turn the phone on.
Thanks for your help.

soft brick, which tar to use?

ok, so my phone hangs at the SAMSUNG, GALAXY S4 screen no matter what I wipe or flash. I want to odin it back to stock and start over, but all I see are the mk2 and nb1 .tar files. I have one of the very first gs4's, had it first day and it rooted without safestrap. Where are those .tar files to odin?

Go to sammobile.com and search. Get the MDL firmware, and be ready to root and freeze the update or put a ROM on it before it updates and you can't exploit it anymore.

Make sure the download is full. Try different USB ports and different cables. Make sure you have the latest Samsung drivers also. If it's giving you an issue still then you might have partially upgraded and might need to flash a newer firmware, but I would hold off on that as long as possible in order to keep your freedom.

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.

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.

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.

Quite a few steps in those threads but I got it working again. I really appreciate all the help/advice given. Now to decide if I want to remove the safestrap screen on boot. Again Thanks.

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:

Had the Wifi Not Working - Fixed

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.

Would I be able to use this fix?
