Background: I attempted to update from SlimKat 7.0 stable to 9.0 stable and discovered my apn's were missing and when I try to add them manually it fails to save. I have also found others with this same issue but none have an easy fix. I'm on UCDLK3 firmware, after restoring to previous state using nandroid backup apn's are present. If I try to flash any ROM (even other than Slim) my apn's are missing, even a dirty flash of 7.0 over 7.0. I know I can fix this by flashing stock UCDLK3 and root/twrp/flash slim 9 and everything will likely work fine. I plan to do just that but want to make sure I'm doing things as smart and clean as possible. There is a lot of info out there and I'm finding it hard to sift through old stuff and find the current state of things.
Question: Is there an actual advantage if I upgrade the firmware from UCDLK3 to UCUEMJB while still planning to use SlimKat 9 Stable with BMS kernel and TWRP recovery? Are there any disadvantages? Either way what is the shortest path to get back to stock (either LK3 or MJB) and flash SlimKat?
Thanks
Your APN may not be sticking because your modem and bootloader may be too outdated.
Some of the latest CM11 and AOSP ROMs require a KK bootloader and modem.
And then there are some roms that require at least a 4.3 bootloader and modem, either the MJ2 (leaked) or MJB (official) bootlaoder/modem combos. I have seen mention of these working in some OPs and in the body of other threads. In some of the later TW ROMs you may have to use a custom kernel like kt747 or iBuddler's. I don't know if any kernel other than the stock in SlimKat and AOSP ROMs would be needed with the MJ2/MJB firmware and modem.
I don't know of any advantages other than some of the ROMs require firmware newer than DLK3 to properly boot, receive data, or have a working wifi. As far as disadvantages, KNOX was introduced with the MJB firmware and stock ROMs, once going to MJB or newer firmware you can not make firmware downgrades without a very real risk of hardbricking your phone. Also you will need to insure your baseband and modem versions match. If they do not you risk hardbricking of another variety.
I had not yet realized that the newer AOSP and CM11 required you to go all of the way to NE4, thank Audit.
Just wanted to close the loop on this thread and say thanks for the assistance!
I now have my phone working properly on SlimKat 9; it really was just the firmware not being compatible with newer ROMs as many have suggested. Here is the sequence I followed to do it but really it probably only needed a twrp flash of the mjb firmware and the ROM install:
1. Used odin to restore to stock LK3 (only because I had messed with things so much and wanted a clean slate)
2. Used odin to install TWRP 2.7.1.0 recovery
3. Rooted with SuperSU 2.40 using TWRP
4. Flashed combined MJB modem & bootloader using TWRP
5. Flashed SlimKat 9 using TWRP
6. Flashed Slim GApps using TWRP
7. Rooted with SuperSU 2.40 using TWRP (Lost root after flashing ROM)
thanks for posting fix. am sure it will help others. audit13 and dawgdoc , thank you for continued help with the awesome Slll. :good:

When you restored to LK3, what Firmware version were you coming from? I'm looking to go to LK3 from the NJ1. However there seems to be cautionary red flags all over the place due to bootloader changes that were made in 4.3.
The OP was already on LK3 with a custom ROM.
Since you are on NJ1, you cannot downgrade the bootloader.

so from what i understand about updating the bootloader to MJB, i can only flash custom ROMs based off TouchWiz 4.3 and up, correct?
but AOSP/CM based ROMs can be any version? as long as the bootloader is supported on that ROM? and worst case scenario, i can flash CM10.1.3 (Android 4.2.2)?
currently i'm on S3Rx 2.2, which uses Android 4.1.2. there would be no point in making a nandroid backup, since the bootloader would be updated and i could no longer use this ROM, correct?

then reboot to recovery, flash new custom ROM.
done.
a mistake i did was i only flashed the bootloader first. rebooted, then flashed new ROM. in which case i had no wifi and data. so i flashed the modem, rebooted, no wifi and data still. rebooted into recovery, factory reset, wipe cache, wipe dalvik, and everything worked fine after that.

You could install the MJ2 bootloader and MJB modem which would allow you the ability to go back. Once you are on MJB bootloader, there is not going back without bricking. If you ever find that you need to revert back for any reason you will be stuck. If this does not bother you, then go for it.

i read somewhere that MJ2 was unstable or something. cause it was a preview leak?
but back to my first question, MJB makes it so i can only flash TouchWiz-based ROMs 4.3 and up? so i will be good to use AOSP-based ROMs of any version?
For clarification purposes:
If you upgrade to MJB you will have the 4.3 KNOX apps (OS) and KNOX bootloader (Firmware). You can easily root following this guide: http://forum.xda-developers.com/showthread.php?t=2538991
Once rooted by following the guide noted above you will have the 4.3 KNOX (OS) removed BUT not the KNOX bootloader. With the KNOX bootloader you will never be able to downgrade the bootloader. What that means is that you can never use odin to flash an older firmware or you will brick!
Now that your MJB is rooted you can flash any ROM you want 4.1.2, 4.2.2, 4.3, 4.4.2 since most custom ROMS dont include the bootloader in the ROM package.
Hope this clears things up?

Yes it does! Thank you!!
I'm on the latest bootloader and modem and I haven't had any trouble flashing any aosp based roms. Only thing I was told you might have to take the bootloader line out of the update script, but so far I haven't had to at all.

Flashing in recovery
If you've downloaded a flashable .ZIP from above, copy it to your SD card or internal storage. Reboot your phone into recovery mode (you can do this by holding "Volume Up" and "Home" while powering on your device; let go of the buttons when you see "Recovery booting..." in blue text in the top left of the screen) and install the .ZIP as an update. Reboot, and you're done.
Note: After flashing in recovery, you need to reboot before you (and ROM installers) actually see the new version number.

would i reboot first, then flash a new ROM?
or should i flash the bootloader, then immediately flash the new ROM?

Hello, I recently just updated my Rogers SGH-i317M to 4.3, which then downloaded a system update which put it at 4.4. I was running Jedi X20, which is based on 4.1.2, when I first tried updating, I flashed the "4.3param_tz" file in odin, and was left with an error screen saying I need to recover using Kies, so I downloaded the official release, flashed via odin, and thats how I got to where I am now. I want to try the "Ditto Note 3" rom, "Sky Note Air 4.3", "Mean Bean" and "Beanstalk". My main question is, can I just start flashing these roms like I was before on 4.1.2, or do I need to use the specific kernel listed on their page? Before you needed a specific kernel to run a touchwiz rom or an aosp rom, so is it still the same? Or can I use my stock 4.4 kernel and try both aosp and tw roms now? If so could you point out the kernels I would need? And educate me on anything else I should know about before flashing 4.3 and 4.4 roms, (I'm not worried about warranty), this would be greatly appreciated. Thanks for your time in reading this and helping me out, much appreciated!!
Regardless of where u are, I'd Odin to Rogers stock KK 4.4.2. Then Odin Twrp recovery, boot into twrp recovery and flash SU v.1.99. Finally choose your rom and flash away. This way you are on the lastest KK 4.4.2 Bootloader and KK Modem/Baseband.

I did all that except flash SU 1.99, so I tried flashing SKynote Air and it didnt work, upon restarting my phone it said no os is available. So I tried restoring from the backup I made of the official 4.4.2 Samsung rom in twrp, didn't work. Tried Odin, didn't work. Then I tried flashing the Skynote rom again and it worked. So I'm afraid of flashing any other roms now.
I rooted my dad's phone a while back ago so he can use tethering in case of emergencies etc. He recently got a smart watch and I wanted to updated it so that he can use it. But it has not been touched since that day. I essentially want rooted stock rom, I'm unaware of where to find that the closest I can find is StockMod kitkat. Which seems to not work on ATT phones? I just want to make sure that I don't brick his only phone on christmas. So is there something I should be aware of?
His model is SGH-i747
Baseband
i747UCDLK3
Build number
jro03
So how do I go about upgrading it? Can I just flash TWRP and flash any rom using TWRP?
I found this, so I should install new TWRP, then flash a specified kernel then flash rom? would this be safe route?
Some of the latest ROMs require a 4.4.2 bootloader and modem.
The simplest and safest way to get the latest bootloader may be to flash back to unrooted stock 4.1.1 and run OTA updates until the phone is running the latest KK ROM. You can then flash TWRP or CWM and a custom ROM.

Would this require flashing with ODIN? I just want it so that it works with root is not required anymore.
Yes, you would flash the 4.1.1 stock ATT ROM via Odin. I prefer Odin 3.07.
You cannot install OTA updates with root.
You can try flashing just the bootloader and modem but I prefer the long slow route of OTA updates.
I rather do it this way, manually so my dad can enjoy it today. I was wondering how can I update it's TWRP? it's at 2.3 but the TWRP manager keeps crashing when I update it.
I highly recommend the latest d2lte version of Philz Touch for recovery.
https://goo.im/devs/philz_touch/CWM_Advanced_Edition/d2lte/
Ok I ****ed up, flash that kernel and did whatever and bam ****ed up. Not working... ****, I still ahve download mode and Recovery but it will not boot into the OS. I get a flash of samsung and then nothing else happends...****
I decided to flash stock DLK3 in odin. Then let the updates take it course (my dad doesn't need root) Where Can I find the file?
The stock ATT firmware is on sammobile.com.
If you want root, OTA to the latest 4.4.2, install Philz, flash supersu via recovery.
Hello all,
About a year ago I flashed v28 (4.4.2) of Omega ROM. I don't believe I flashed an sgh-m919 specific version, though I don't quite remember, and through a few searches I couldn't find the same older thread for the ROM. I also don't remember if I flashed anything else, bootloader, modem, kernel etc. I feel like I might have flashed a modem at the time. Possibly a kernel but I don't think I changed anything about my kernel.
My phone is getting slow and unstable and I'd like to update to v41 (latest, 5.0.1) of Omega ROM. The thread is over in the international i9505 development forum. I barely remember how any of this works anymore beyond simply putting the ROM on my sdcard, wiping everything, and flashing through recovery, and so the mention needing to flash XXUHOB8 bootloader and modem in the Omega ROM installation post made me question whether I could simply wipe and update, since the bootloader and modem are for international i9505 and I have the t-mobile phone.
Also, Im going to flash the latest version of TWRP. Initially I would think I would flash jfltetmo, as per the tmobile s4 TWRP on the TWRP website. But if I'm using an i9505 rom, do I need to flash the international version of TWRP (jfltexx)?
Basically, my question is, should I expect any problems if I just flash the i9505 bootloader and modem to my sgh-m919 and then flash the new Omega ROM? Do I need to do something with the bootloader and modem specific to the sgh-m919?
You don't need anything i9505. Just update to 4.4.4 NK2 firmware with odin and flash the latest twrp, followed by the rom
Hey all. I am fairly inexperienced when it comes to rooting, though I have done a few succesfully in the past. I currently have the newest version of TWRP installed on my Samsung I747M. The I747M I have is not from one of the major carriers, but as far as I am aware, the phone is factory network unlocked. Carrier is GCI, in Alaska.
I currently have a 4.4.2 Touchwiz Rom installed and started having problems after I attempted to flash the ROM Dandroid, which is 4.3 (http://forum.xda-developers.com/showthread.php?t=2121506). I had created a backup using TWRP before flashing the ROM and reverted back once I noticed the problem.
The main issue I am experiencing at this time is the Baseband Version, IMEI, and other information related to the modem is showing "Unknown" and features such as wifi will not toggle on.
I had also attempted to flash the most current version of the modem that I was able to find thru Odin. Odin showed the flash as successful. The version I flashed to the phone was I747MUMUEND3: modem_CWM_I747MUMUEND3.zip - 18.80 MB - April 3rd, 2014 (http://forum.xda-developers.com/showthread.php?t=1831898)
At this point, I can still get into recovery, download modem and I am able to boot up the phone and access most all functions. The next step I was going to try was going to be to flash back to stock firmware from sammobile's website (Was using to use the Roger's version of 4.4.2), though I don't want to cause more issues than I can handle or resolve thru software.
Any advice on how to proceed would be greatly appreciated or even just how to get the modem/wifi features functional again would be helpful. I'm just as happy staying on my current ROM at this point if I can get the phone fully functional again.
It's possible that the rom is not compatible with the kk modem and bootloader.
Flash cm12.1 to see if your imei comes back.

Forgot to mention, this is something I did try. I attempted to flash Cyanogen Mod 12.1 (Download: cm-12.1-20151017-NIGHTLY-d2att.zip (286.76 MB) ) and most recent nightly build & the most recent stable release (CM11) (Download: cm-11-20140210-SNAPSHOT-M3-d2att.zip (194.37 MB) ). When flashing these, I transferred the downloaded ZIP file to the internal storage of the phone in the root directory and attempted to run an install from TWRP. Both installs failed.
Since the phone is an i747m, I recommend flashing back to stock using Odin 3.07 and stock ROM file from here: http://www.sammobile.com/firmwares/database/SGH-I747M/
The i747m versions are interchangeable between Rogers, Telus, and Bell.
After flashing back to stock, install TWRP using Odin 3007 from here: https://dl.twrp.me/d2att/twrp-2.8.7.0-d2att.img.tar
Create a nandroid backup using TWRP and then try to flash a custom ROM again.

I'll give that a shot when I get home. Stock firmware was one of my next thoughts. I have it downloading at the measly 15 Kbps offered for free from sammobile so hopefully should be done by the time I get home & update this thread with any progress.
Another possibility is a custom kernel, if you are wishing to stay with TouchWiz and not wanting to upgrade your bootloader and modem past 4.3.
Some of the 4.4.2 TW roms will run on 4.3 bootloader and modems using one of ibuddler's kernels or ktoonsez's TW kernel. This was discussed most in the Likewise ROM thread and links to the various versions of ibuddler's kernel may be found there. It may have also been discussed in TMS3KK thread. The ktoonsez kernel can be found in its own thread.
But, you may really want to consider a newer ROM in order to change to something with the stagefright fixes. I think any of these may require the latest 4.4.2 bootloader and modem. (What say you @audit13?)

I'm not opposed to any of this. Mostly just trying to slim down this phone to the basics as much as I can and am quite open to any recommendations. Main thing I want to maximize is battery life & simplicity since this is for my wife and those are her major wants in a phone. I figure any kind of ROM that just covers the basics should cover my bases & would prefer one with a darker/black skin to maximize battery life w/ the OLED screen. I am in the process of flashing to the Roger's stock ROM as I type this w/ my fingers crossed.
Just to add, no over clocking or anything of that nature is desired. If I remember correctly I ended up putting the ktoonsez kernel on one of my handsets, either this Galaxy S3 or my Galaxy S5, though I can't recall which since it was so long ago.
Alright! So progress! Wifi, Baseband version, IMEI and all other missing information restored & now works w/ stock rom flash. In process of reflashing TWRP now.
Let us know what happens.
Still all good with TWRP installed. Have not flashed back on a custom ROM yet. After reviewing some of the above recommendations, I am kind of liking the looks & features of TMS3KK (http://forum.xda-developers.com/showthread.php?t=2725750) and feel it would suit my needs.
I factory reset, cleared cache, and cleared Dalvik thru TWRP & then made a back up. Prior to this, I confirmed everything was still working normally w/ phone fully loaded after TWRP was installed.
One of the things mentioned on the installation instructions for that ROM is the following:
---
Do not mix and match 4.3 firmware (bootloaders/modem) with the new 4.4.2 ones. You will hard brick and I warned you. This works the same as any 4.3 or ND8port ROM with 4.3 firmware and it can use the new 4.4.2 ones also.
Link to recovery flashable i747 and i747M 4.4.2 bootloader and modem packages: http://forum.xda-developers.com/gala...hable-t2856914
---
How would I go about confirming my current bootloader/modem versions to make sure they are both 4.4.2 before flashing this ROM? At the link provided, those files/links to the files were removed because they were causing some bricked devices per a note at the top of that thread. Here's a link to the thread I am referencing since the above link looks to be broken. (http://forum.xda-developers.com/gal...mware-ne4-ne6-nf2-recovery-flashable-t2856914)
If you flashed the latest stock rom, you are running the latest 4.4.2 bootoader and modem.
You can download and run the Samsung phone info app from the play store to confirm this.
You should be good to flash any d2lte or d2att rom.
I recommend not flashing any modem or bootoader from this point forward unless the bootoader and modem are newer than the currently installed botloader and modem. Also, the botloader and modem must be matched to each other.

Thank you so much for the help and information. I guess I never realized that the bootloader & modem were installed w/ the stock rom as I always have flashed those separately through Odin when needed. Definitely good information to have and not easy information to find. I have successfully got my custom ROM on there and am now fine-tuning it for the wife.
