[Q] [Solved] TWRP Restore / I337UCUAMDL Odin Restore

Hello all
So I have been doing some flashing and I wanted to restore to the original stock ROM that I made a backup of (via TWRP) right after I rooted my device using the Casual tool in the dev forum but I had a question just to make sure I don't botch anything before I go for the restore:
I am coming from CleanROM 1.5 the MF3 based ROM -- I'm assuming the ROM didn't touch the bootloader
1) I performed an Odin recovery of the I337UCUAMDB baseband version of the OS (factory) from the Dev Forum
2) My original backup was of the I337UCUAMDL baseband version -- Am I able to perform a TWRP restore without causing any problems here?
3) Do I have do Loki-Doki after I restore?
I would try this myself but I really don't want to risk a hard brick in case this isn't the correct way - thanks for the advice in advance all.
An Alternative to this would be to obtain the Odin PDA file for the I337UCUAMDL baseband firmware which I have been unable to locate

Alright well I just went ahead with the restore and The baseband version stayed the same despite the fact that the backup was originally from the MDL baseband. Is there anywhere I can download the Odin file to flash the MDL firmware?

No one's helped me with my problem, so might as well help you out lol! Here's a link for MDL http://storagecow.eu/Xda/AT&T S4/St...s.com-SGH-I337-ATT-I337UCUAMDL-1367050591.zip Flash with Odin

I just did some digging around and actually found this awesome website and I am downloading the MDL right now
http://www.sammobile.com/firmwares/1/?model=SGH-I337&pcode=0#firmware
I do believe that this is legitimate - if not someone please correct me. Have 2 hours until the download is finished anyways lol

Thanks for the offer -- but as long as the steps are essentially the same as Adam's Factory Stock thread in Android Development then I should be alright! I'm assuming that is the case

they should be (post a link ill check).via ODIN, install UCUAMDB, then UCUAMDL, root and install custom recovery, and freeze the update processes (i forget what they are called, im looking for them now) with titanium backup so that it does not auto update to MF3.
if you happen to know the process names or find them, please PM me im making a thread about it.

Yes, Currently have the MDB installed and running, going to enter download mode and flash MDL via ODIN and basically my plan was to freeze the AT&T auto-update checker application - I have frozen it before and I'm guessing that is the first application in the chain that initiates the update. I'll keep ya posted the MDL is still downloading lol

When you finish downloading and flash firmware by oding go ahad and root ifno here : http://forum.xda-developers.com/showthread.php?t=2314494 then install GooManager from play store https://play.google.com/store/apps/details?id=com.s0up.goomanager&hl=en open and from menu choose install script. good luck

All of the information in this thread is readily available in the stickies located in the "General" section. Looking at those threads might save you a lot of time, some potential problems down the road, and help from making mistakes that have already been mentioned. Good luck.

The firmware from (http://www.sammobile.com/firmwares/1/?model=SGH-I337&pcode=0#firmware) was spot on. Used Odin to restore. Already re-rooted and froze a few of the update apps. Thanks all for the help, added [Solved] and altered the title to help guide searches

[Q] The Ultimate BRICKED Samsung Galaxy S4 Challenge =)

Long Story As Short As Possible:
1-I Rooted my Sprint Galaxy S4 (with MF9) using Qbking77's You tube instructions (No Probs) !!
2-I dropped the Services.Odex, and Services.Jar into the systems/folder to replace the ones in there using root explorer to get the native hot spot working (It did NOT work) !!!
3-So I flashed via oden a "New" hot spot for rooted roms: "MDCHotspotMod-Odexed" onto the system, and now I am bricked...
I can boot into TWRP, BUT can't flash a rom to the system as it Fails.
I can flash the root "CF-Auto-Root-jfltespr-jfltespr-sphl720.tar" via oden which puts the stock recovery back onto the phone, BUT that wont't flash roms either.
SO, at a complete loss, I factory reset the device wiping everything, and it just boots to the Samsung Galaxy S4 Logo.
I downloaded the following: L720VPUAMDC_L720SPTAMDC_L720VPUAMDC_HOME.tar.md5 to try and flash back to stock in Oden, BUT, when I hit "Start" it doesn't do anything but say "The Parameter is incorrect"
This is the Stock MDC File, NOT the MF9 that my phone was currently on...
ANY SUGGESTIONS !!! Thanks guys.

Solved !!! Used MF9 Stock Tar file in Oden !!!

Glad you got it working!
Just in case you were wondering why it didn't work initially - you were on MF9, and you tried to flash the MDC hotspot mod.
And yes, flashing the stock MF9 in ODIN was the right step to fix this. If you now want to install the hotspot mod, make a nandroid backup, download the MF9 version and flash it in TWRP.

Any word on getting the hot spot feature working on the MF9 ?? Either Wifi Tether (specific settings), OR the regular built in Hot Spot?? Thanks... Also, I def know about the different software versions I.E. MDL, MDC, and MF9, the site said that particular file would take me back to stock & I would just have to OTA !!! Guess they were wrong, lol...:laugh: Anywho, thanks again, it's nice being able to get help when needed !!!

Yep - this is the one that I use as well.
@Ar3ohdee Just make sure that you get the correct version depending on your ROM - odex/deodex and MDC/MDL/MF9
BTW, if you were on stock MDC, you could update OTA to MDL and then to MF9 - that option would have worked too. But flashing the stock MF9 is quicker.

just bricked my galaxy s4 and its stuck at samsung custom screen.. cant get it out of it.... what do i do.. i'm new to this and i new i was going to do this sooner or later....

you may need to give us more info than that. what did you try flashing? were you already running a custom rom? mdc, mdl, mf9? did you try manually booting to recovery? (power + vol up)
open a new thread too, may have better luck

Bricked on mk2
So I was on stock rooted mk2 with twrp recovery. Did a nand. Flashed kt kernel. Phone wouldn't get passed Samsung splash screen. Couldn't even boot into recovery. Took it to best buy. Tech, if you can call him that, said was bricked and I needed a replacement. Luckily just bought it so free replacement. Played dumb. Probably could have recovered if I Odin the stock firmware. My question is, what do you think caused the brick? Mk2 bootloader? Twrp? The kernel? I flashed plenty of roms and kernels on my s2 without problems. BTW flashed Hotspot mod with cwm and worked.

4.3 downgrade -> 4.2.2 epic fal

I just did legend fail.
Been on stock MK2 (MF3 sideloaded to upgrade MK2), then i decided to go back to 4.2.2 stock since i really did not like the 4.3, did not make any research, so i odin the MF3 files and tried to flaash, but got an error in first 5 sec. Now every time i switch on the phone its saying i have to make upgrade through KIES, what sounds work w/o luck.
I know we dont have 4.3 odin files yet and not sure we will have them, but is there any way still to get this device to work ? Or its absolutely broke ?
Would appriciate any help ty

If Samsung experience at best buy has the new update, you could try to see if they could help. If not, I feel you are in for a wait.

I did the same thing on my SGH-I337M. Kies was a waste of time. I used Odin, downloaded the newest 4,3 firmware and reflashed it in update bootloader section only. Took about 8 minutes but saved my phone. Knox won't let us downgrade so we are sad at the moment.

can any1 please share this file bootloader of MK2 so i can flash it throu odin to make the device to work, would appriciate any further info or help ty. w/o phone for 3 days already

I know you used the xda app so you probably didn't notice the OP is located in Athens, Greece. So no dice

Yeap got the phone from my bro he is leaving in Rochester, if i would know that he sent me At&T and its as block as it is now, i would spent money to buy it from Amazon Germany, internatioonal fully functional =) but my luck

Since we got the 4.3 update closing our download funtion in phone, will we be able to flash through odin the stock 4.3 MK2 to re-stock bricked sgs4 ? like you can do with MF3?
I am asking since currently i am w/o phone and waiting for someone to post the stock MK2, but will that for sure make it work normal excluding its blocked downlaod etc. ? just curious

Same thing happened to me.. I worked for hours and finally just tried flashing the I337 PIT file thru Odin in the Pit option.. It said failed but I pulled the battery and rebooted into recovery then restarted.. Google for the pit file.... I have the full zip MK2 file but you have to have the MD5 files for Odin
Sent from my GT-N8013 using xda app-developers

If i will flash PIT file i will be able to enter recovery ? since know the only option i have is download mode, and kies recovery (what is useless)
When u flash PIT with fail and enter recovery what did you do next ? the device booted normally ?
Where can i find this PIT ?
Ty for the help

So let me ask this so I do not make a similar mistake. Yesterday I used odin to go to mf3 then sideloaded mj9,. If I have the file for mk2. Can I just side load it even though im on mj9?

Yes, you should be able to sideload or flash the zip through recovery.. With all these fails at updates, I wish I would have stayed at what I had and not messed with it..lol.. It seems nothing is guaranteed and it's always a risky chance when you flash something..

I decided to update to 4.3 and didnt like it so i stock flash 4.2 back via odin. flash said "pass" but now i have knox on recovery. Im guessing i have the new bootloader. 4.2 flash on but with errors like wifi wont toggle on & on every reboot i get an erro "kernel seandroid is not reonforsing" or something like that...so now im stock on 4.3 :/

The mistake i made was to go downgrade from 4.3 to 4.2.2 do not make it since we do not have files for ODIN flash 4.3.
There is full 700 mb file witch you can easily sideload, if u get any error just go back to odin to flash stock MF3 and then sideload MK2, worked for me w/o problem but pls do not downgrade !
If i were you i would not go 4.3, TW is much more bugged for me, and phone feels way different thats why i wanted to go back to 4.2.2

I was able to downgrade... kinda..
I had my own epic fail when bell's update came out.
Flashed stock/counter reset.
Got OTA update no prob.
Rooted - Deleted too much bloat... (didnt backup) MY EPIC MISTAKE.
Thought "oh ill just start again"
Odin Back to 4.2.2 FAIL!!!
Stuck.. kinda
found someone with the international version in the same issue that odin flashed files from another carrier and was able to fix his situation...
so i went to http://www.sammobile.com/firmwares/ and downloaded the NEWEST date 4.2.2 rom for my 337m, which happened to be Dominican Republic carrier.
Flashed the DR version successfully in odin, and had no sound, no mic, no wifi.
I was then able to Odin flash 4.2.2 from bell... but still had no sound, no mic, no wifi....
the only real fix was LUCKILY within 24 hours of the OTA release, the odin file was posted to sammobile and saved my ass... all works now.
Played with the 4.3 update for a couple hours, then went back to 4.4 builds... LOL
At least i got to use my captivate again for a few calls for a day. that was nice.

Really have no idea how i an fix this w/o odin files.

umm you cant.

Problems solved, any1 who will have the same issue as me:
Had MK2 update installed and wanted to downgrade to 4.2.2 and failed to kies update, just flash the attached filed, it will fail you in download mode, but after 2-3 tried, just restart the device, and it will normally boot into 4.3 =)

[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.

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.

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.

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.

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:

Would I be able to use this fix?
