[Q] Cannot update bootloader?

Hello, I was originally running a beta version of Panandroid 3.99, and then I flashed a Stock modified Tmobile Rom on 4.3. I wanted to see if I could get wifi calling to work on it and it did, then I wanted go back to Quantum Rom.
For some reason I could not get Quantum Rom to flash, TWRP would read a "unable to .zip or something like that. Then I read I should update my Bootloader and Modem. So I restored an old backup to Cyanogen mod 10.1.2 (4.2.2 Update). I was able to flash my modem to the MJB update, but whenever I tried to flash my bootloader to the MJB update, TWRP and CMW would both give me Status 6 errors.
I am currently on the LK3 modem as stated by my Terminal Emulator.
Any suggestions on what I should do?
I'm also confused on how I was able to flash Panandroid 3.99(4.4.2 KitKat) on the LK3 modem? Should I have needed the MJB modem in the first place?

The bootloader and device ID is normally what determines if a rom can be flashed to a phone, not the modem.

Visit the S3Rx post and scroll down to the download area and you will see the modem and bootloader flashable zips. I would go with the MJ2 bootloader /MJB modem combo to allow you to go backwards in bootloader if needed.
You may need to update TWRP to the latest, I understand that 4.4 roms require the latest.

I think you meant the MG2 bootloader, which did install fine. After that, I was able to flash Quantum and GAPPS.
Thanks a bunch! :highfive:

Glad that fixed the issue. :good:
Actually, I meant MJ2. Interesting enough I now see is not on the boot loader list thread (http://forum.xda-developers.com/showthread.php?t=2321310) and appears to only be found on the custom 4.3 TW roms sites (which references to the S3RX rom thread (http://forum.xda-developers.com/showthread.php?t=2252932).
LK3 - 4.1.1
MG2 - 4.1.2 (OTA)
MJ2 - Leaked 4.3
MJB - Official 4.3 (OTA)(make sure you read the warnings if you go to this boot loader - there is no going backwards)
So unless you need to go to a 4.3 boot loader, which it sounds like you do not, I would stay where you are.

UCUFNE4 to UCUFNJ1 update 16 gig AT&T I747

The development for the AT&T I747 has been discontinued by the developer. Thank you for your support.
WARNING: YOU COULD BRICK YOUR PHONE
UCUFNJ1 4.4.2 incremental update contains firmware.... bootloaders and modem baseband.
MUST BE ON UCUFNE4 FIRMWARE TO CONTINUE!!! Guide can be found here. http://forum.xda-developers.com/gal...are-update-t2808654/post53984772#post53984772
This is the perfect time to use this update to return your S3 to stock for resale or whatever. Download and save these files for when you are ready to return your phone to stock.
*This is a rooted NE4 system.img, stock recovery.img and boot.img. The install script will format system and factory data reset. /media is safe.*
1. Flash restore zip in a custom recovery. CWM, TWRP, Philz. https://www.androidfilehost.com/?fid=95784891001611561
2. Boot your phone and go through setup.
3. Use triangle away and clear your counter. http://forum.xda-developers.com/galaxy-s2/orig-development/2014-01-15-triangleaway-v3-26-t1494114
4. *Optional* If you want a clean un-rooted phone for the update do this now! , Go into SuperSu >settings>full unroot.
5. Reboot your phone.
6. Search for the OTA in the about settings, download and let the phone update.
Or download this and place in the root of your phones internal storage. Reboot into recovery and select the update from update.zip https://www.androidfilehost.com/?fid=95784891001611091
Advanced users.
The original OTA cfg file. https://www.androidfilehost.com/?fid=95784891001611092
.cfg file goes in root/cache/fota
Rename the .cfg extension to .zip and you can rename it update.zip yourself or you can actually flash it in a custom recovery once renamed. if you choose not to use the stock recovery to update.
*You will loose root during the update* But the bootloader is not locked so you can still Odin your favorite recovery and flash SuperSU.
TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.8.1.0-d2att.tar
SuperSU http://download.chainfire.eu/589/SuperSU/UPDATE-SuperSU-v2.16.zip?retrieve_file=1
Once you flash your favorite recovery via Odin, you need to be ready to hold the Volume Up, Power and Home button combo when Odin reboots your phone. If you don't catch it, once the OS boots it will replace recovery with the stock version. Once SuperSU is installed your recovery will stick.​

Doing Vice Versa Method?
Just to be clear, what if my galaxy s3 is on UCUFNJ1 and I want to go back to UCUFNE4, I can still ODIN the custom recovery and flash SuperSU?

For the advanced users, should we be able to install the update without any issues? I saw in another thread that someone had installed but now their phone will not boot past the Samsung logo to anything other than a black screen.
Also, do we know what this update contains yet? Other than new bootloaders, removal of root, etc.

You know if your not wanting to return your phone to stock I really wouldn't mess with this update. Far as the user who couldn't boot... Idk I wasn't there to watch them update. This whole mess with the S3 is exhausting. We haven't got a real Odin release so I'm woking with what I can extract from my phone after updating. The system.img in ne4 zip is 100% stock except for root. So I know the update worked because I did it. Also not sure what was updated either... The kernel yes... Firmware yes, all the system apps get patched so without decompiling ne4 and nj1 apps and comparing them afraid I have no idea what the update fixes or improves.

Thanks for all you do for us S3 owners, enewman17.
If we upgrade to the new NJ1 firmware, and then flash your latest SRX Rom, I assume we cannot then use your "restore.zip" to once again go back to NE4 stock since we would be on NJ1 bootloader? If so, is there a way to go back to NJ1 stock if we later want to sell our phone?

Towelroot no longer works after the NJ1 update. Can the CF-AutoRoot still be used? The only version at http://autoroot.chainfire.eu/ says it's for 4.0.4.

Yeah, I saw that, but I never had a custom recovery before, that I know of at least, and I suspect a lot of other people finding this thread in the coming days are going to be in the same boat as me. They just want SuperSU so their favorite 1 or 2 apps that require SU can continue to work.
Has anybody tried CF-AutoRoot yet on the NJ1 4.4.2?

I can confirm this as a root method for NJ1. You were exactly right regarding immediately booting into recovery after installing TWRP thru Odin. The files provided in your links (TWRP 2.8.1.0 Odin tar. http://techerrata.com/file/twrp2/d2a....1.0-d2att.tar and
SuperSU http://download.chainfire.eu/589/Sup...etrieve_file=1)
worked exactly as stated.
A BIG thanks to you. I can't live without AdAway, TiBackup and Xposed anymore! The few days without root left me a little grumpy.
And regarding the NJ1 update as a whole...I THINK the baseband upgrade IS an actual upgrade. Since NE4, I always thought Wifi operated was somewhat choppy/throttled. THIS looks to have been improved back to ICS "standards". Re: voice, I've had a handful of dropped calls, broken up calls, and choppy data in low signal areas over the past few months on with NE4. Initial observations (albeit a tad premature) lead me to believe that this has improved as well based on a weeks worth of data use and a few calls in a "controlled" environment (the area and physical structure of my work office complex is not cellular signal friendly to begin with) I have also noticed that boot-up time has improved a bit as well. Thanks again for your efforts with the ATT GS3!

I flashed CF-Auto ROOT via Odin without success, unable to gain root access. Followed your instructions via TWRP and flashed SuperSu 2.16, my SGS3-i747 is properly rooted and functioning perfectly on UCUFNJ1. As always, thank you very kindly for all your valuable time, effort, hard work and guidance. Be well, sir!

What version of Odin do we need to flash that TWRP, or do you have a link handy?
I've seen quite a lot of different Odins out there and don't want to brick my phone by using the wrong one.
Any pitfalls to watch out for if using TWRP for the first time? I'm sure there is going to be a bunch of people having to do this now that both CF-AutoRoot and TowelRoot doesn't work anymore.
For me, personally, I just use root for AdFree and to edit the font fallback order to properly support Japanese instead of Chinese glyphs on shared Han-unified Unicode codepoints.

Use Odin 3.0.7
Not really any pitfalls to TWRP. It has an easy clean user interface and it works.
Once you have flash Super Su, in my how to ne4 update there is a flashable stock recovery. You just flash it with TWRP and once you reboot, stock recovery will be back on you phone.

Hi enewman17,
Thanks for your posts and work. I'm hoping you can help me get the new NJ1 update installed and rooted.
Here's where I'm at: AT&T SGS3 on rooted stock NE4, installed using your guides from back in June this year.
The OTA NJ1 update downloaded but failed to install (as did the NE4 OTA back then, I assume because I was rooted).
My phone still has the TWRP recovery from the previous update, so I was hoping I could install using the original OTA cfg file download from the "advanced" section in your OP so as to avoid factory reset, etc.
I downloaded the file, renamed to update.zip, and copied to my SD card. However, when I boot into TWRP and try to install it, I get an error after the system check, something like "assert failed ro.secure==1". I guess I'm doing something wrong, maybe I'm mistaken about how the original OTA is supposed to work?
Again, I'm trying to end up with a stock, but rooted, NJ1 firmware but hopefully without having to reset/lose data and settings on the phone. I don't really care right now about resale or making it look like I haven't messed with it.
Thanks for any help you can provide! Let me know if I can provide any additional details.

I am actually looking to do the exact same thing. Currently rooted, with a lot of the AT&T apps frozen via Titanium Backup.
Hope there is some way to accomplish this without returning to stock!
Thanks in advance!

Do you guys want it packaged with the stock recovery?

[Q] No carrier/SIM support after 4.3 stock restore

My ATT SGH-i747 was rooted and running 4.4.2 until an OTA this past weekend soft-bricked the phone. Phone would boot to a blank screen but still allowed access to download and recovery modes, thankfully.
With help from this awesome forum, and a stock 4.3 flash via ODIN, thanks to enewman17's epic efforts and thread , the phone is back, but now won't recognize the SIM - and baseband version is "unknown" - I suspect I need to now go up to 4.4.2 to get the hw recognized by the sw. Went to ATT and they put a new SIM in but to no avail
CWM recovery is gone, but I can reload that easily enough...
Do I need to just flash the modem, or is the bootloader involved too?
Is there a single flash or .zip that will get the ROM (incl CSC and Modem) up to 4.4.2 in one shot?
I never really wanted to go this deep but here I am so now I'm looking for advice or direction as there are so many directions to look... thanks in advance!

Mismatch in firmware
Digging deeper, using Phone Info *Samsung*, I have noted the following
bootloader version: I747UCUFNJ1
baseband version: <blank>
pda version: I747UCUEMJB
csc version: I747ATTEMJB
skip a bit...
modem version: <blank>
hardware revision: <blank>
mobile operator name: <blank>
mobile network code: <blank>
So it would seem I have a mis-match of versions, where it seems all should be the same..
Would it be safe to flash to MJB following this thread?

Your modem (baseband) appears to have been compromised in the process of downgrading from Kitkat. You could try either of the following solutions...
1) Flash the UCUEMJB modem via custom recovery to return you to complete stock 4.3. You can see the modem file here ....
https://www.androidfilehost.com/?fid=23269279319197285
2) Do a complete stock restore to 4.4.2. You can find the stock update zip via the following thread ...
http://forum.xda-developers.com/galaxy-s3-att/general/ucuemjb-to-ucufne4-firmware-update-t2808654
If you can reflash the 4.3MJB modem, you can check to see if you can get an OTA update to 4.4.2. Using Option 2 requires you to be on complete stock 4.3 so this may not work if you currently don't have the baseband/modem. I would strongly advise you stick to the custom recovery flashable files for now and avoid Odin. You would, however, need to restore custom recovery via Odin.
Hope this works for you.

Thanks for the detailed reply with links, Larry :good:
So I guess my plan of actions will be
1) re-install custom recovery w CWM to my external SD card as was previous
-do I *need* later version of CWM? Previous one of mine was 6.0.2.3, IIRC, that is what I can easily flash back to the phone
2) install .zip (from https://www.androidfilehost.com/?fid=23269279319197285) via CWM
If that doesn't work, I was interested in the S3Rx ROM vs. a stock 4.4.2 ROM - is there any way to go straight to a custom 4.4.2 ROM or should I get the modem working in 4.3 first?
Lastly, Where can I find a later version of a CW Recovery Touch .tar to flash via ODIN? (third stoopid noob question in this post, I know...)

You aren't the first to have this issue. This is why I am still on NE4 and did not take the OTA to NJ1. The update is pointless anyway, all it does is patch the kernel so towelroot won't work anymore aside from updating the bootloader.
Since your bootloader is NJ1, that is your firmware which cannot be downgraded. If you try, you will brick. You have to work with NJ1 files here only. Sure you can flash older modems, but stick to NJ1. I suggest using ODIN to flash a custom recovery, then use enewman17's NJ1 .zip file in said recovery to reflash all the NJ1 stuff. Then do a complete factory reset. You might need to flash stock recovery to do the hard factory data reset, as I am not sure if it can be done in CWM or TWRP.
In the future, I suggest freezing the update and not upgrading until people on here do it and report how it's working or rather not working in this case.

I have CWM and TeamEpic v5 on external SD, so a version of custom recovery is there (CWM 6.0.2.3) - but do you have a link to enewman17's NJ1 .zip /recovery?
As far as freezing the updates in the future, yes. I tried to keep the OTA push from happening, apparently not ardently enough :crying:

You might want to post in that thread asking if it works when you are already on NJ1 though, or get a hold of enewman17 via PM or something.

SOLVED!
enewman17 posted NJ1 modem .zip here, and now me has modem and cellular service again!
Question: can I update the thread tag from [Q] to [SOLVED] myself?

You'll have to format your internal sd when going from Lollipop to KitKat. Afraid its the only solution.

Good to hear from you enewman17. Question, if I return to stock unrooted NJ1 first, should the OTA work? It says it is "checking", but after awhile gives me an "interrupted" message and says to try again in 24 hours.
Download mode says official with warranty bit 1

Enewman17, I know that you are one of the sharpest fellows on this phone. Do i need to update to NJ2 before i flash this? Is there somewhere i can find that modem, and is it worth it as far as performance goes? Thanks for a new build. Your roms are always spot on. Thank you very much for the good job. I know i will enjoy it.

I use the stock rooted zip I had uploaded and that worked for me. Once I got the update I grabbed the OTA file, copied to my ext sd and renamed to update.zip. Then I flashed the stock recovery and selected install update from sd and installed the update zip that way.

You will need to update the firmware to NJ2 or your wifi will not work on this rom. The bootloaders and modem are linked in the OP, I don't use the phone so I can't comment on any performance really. I did notice that NJ2 definitely seems snappier and I did read in my general posts that someone had better data speeds. after updating the firmware.

OK sorry to be dense, but are you saying you returned to NJ1 unrooted stock using your earlier NJ1 rooted zip? And then you went to Update Check and downloaded the update? I am on your the same NJ1 unrooted stock, but I get the "update was interrupted" message trying to grab the update? Is this normal due to server traffic? Or do you think I need to try something else.
Just trying to see if I am able to grab OTA the usual way.
Thanks

I didn't unroot I left it rooted. I used this zip https://www.androidfilehost.com/?fid=95784891001613266
After a clean install I logged into gmail and all that jazz. I waited about an hour before I checked for an update... let all the apps update and everything. Maybe that's the key is to wait a little bit. I'm not sure about or what the update interrupted message is about... could be network traffic.
The only thing I did differently is I didn't let the OTA reboot and install. I renamed the file to update.zip and flashed it manually in the stock recovery.
I've attached the 2400258.cfg OTA file for anyone who wants it. Will have to unzip...

Did you use Triangle Away and flash stock recovery on the NJ1 before grabbing the NJ2 update?

I did not use triangle away and I actually didn't flash the stock recovery until I was ready to do the update. So I actually got the update while I still had TWRP installed.

Ok, my only other suggestion is to flash the stock recovery and do a wipe with that.

Searching around, somebody said they had luck flashing CM 11 then flashing TW. I'll try that first. Thanks.

One additional thing you might try after the full wipe is flash the bootloader/modem zip and then the ROM. I've done that a few times and it's worked

Will you update your awesome ROM with this update?

Something that worked for me. Flash Carbon rom. Then let it boot up. Just go through the info stuff. Reboot into recovery, then flash it. Make sure it is on your sd card. Internal storage wouldn't work for me. Then you should be golden. There is a new bootloader/modem that enewman put up. I flashed it. NJ2. Some people say that it works better. I am still seeing for myself, but it does seem a little stronger, signal wise. Hope it helps.

[Q] Help with going back to stock (from CM11)

Hey, sup?
I need your help, I'm trying to go back to stock firmware on my i747, currently I'm running CM11 latest snapshot.
Background: Some time ago, I accidently erased my imei. Took the phone to a guy who restored it but the phone doesn't work with 3G now, only 2G. So I wanted to try going back to stock firmware to see if that fixes the issue.
I tried downloading the CUEMJB file from here, but it doesn't work (keeps looping the same page) http://androidromupdate.com/att-samsung-galaxy-s3-sgh-i747-odin-stock-firmware/
Can you help me? Also, it is safe what I'm trying to do?
Thank you!

Triple check to make sure the imei displayed in About Device matches exactly to the one on the sticker under the battery.
If it does, and after you get stock working again, PM me and I can probably help.
As for the looping, do you mean the Web page? Just get the stock files from enewman17's thread. It's either in General or Development, can't remember for sure. Probably General.

Thank you. Yes the IMEI matches.
I was able to download the file.
Unfortunately, the thing didn't went ok. After flashing my phone is unresponsive, black screen, no more boot
If I connect it to the computer at this point, it tries to search for a QHSUSB_DLOAD driver. Not sure what is that, I think I bricked my phone.
I've seen some guides for unbricking by placing a sd card in the phone at boot but so far it haven't worked

Going to one of the 4.4.2 bootloaders and modems for your device may fix the issue, maybe without going back to stock. But I do recall that a return to stock has been required by many. If you are on newer bootloader and modem than 4.3, do not use a 4.3 (MJB) file no matter the source. As Doc said use one of the releases by enewman17 that you can flash in your custom recovery, NE4 is here. enewman17 also has threads for MJB, NJ1, and NJ2 stock ROMs; all of these are flashed in a custom recovery. With the i747 I have continually seen it recommended that you upgrade bootloader and modem sequentially, that is upgrade to NE4 before going to NJ1, and NJ1 before going to NJ2. I can provide links to enewmans other threads if necessary.
BTW, the 4.3 release was not a full rom, it was an update/patch. Files I have seen run 100 mb or less. If that is the file you want, and can use w/o bricking your device see this thread http://forum.xda-developers.com/showthread.php?t=2722660 Only use it if you are on 4.1.1, 4.1.2, or 4.3 bootloader and modem.
Another way to get a 4.3 Odin flashable update is here. You must be on 4.1.1 or 4.1.2 bootloader and modem to use this as instructed.

Thank you very much.
But I'm with a phone that doesn't boot now. What would you recommend to do if there's something to bring it back

Alright! I just tried the SD card method w/ one of the files in the threads linked. Phone boots!
So it seems my bootloader is bad right?

Can you get into recovery? If so you can flash the appropriate stock rom by enewman17.
Do you recall what bootloader and modem you were on? If you have TWRP as your recovery there are terminal commands you can use within the recovery to determine your bl/modem versions. This may also hold true for CWM and Philz Recoveries, but I don't know for certain.
If you can not get to recovery you may need to put a debrick image on an external sdcard to boot and then restore your device.

Yes sir. With the SD card method I managed to boot the phone. Yay!
I don't recall bootloader and modem unfortunately. I know I was using CM11 one of the latest snapshots for d2lte.
I have access to download mode. Screen reads bootloader RP SWREV:2
I have access to recovery (its a basic one though). Reads Android system recovery <3e>
What do you recommend from here?

That is the stock recovery. If you were successfully running one of the latest CM11 snapshots, you were probably on one of the three 4.4.2 bootloaders ( and modems ), they are NE4, NJ1, and NJ2. This would explain why the MJB (4.3) image you downloaded and flashed would soft brick your phone. It looks like that flash may be responsible for you being back on stock recovery, at best guess. Before anything else, do a factory reset from the stock recovery. This is frequently necessary to boot when going from a CM/AOSP LP rom back to stock.
Since you can get to download mode, I think the best bet would be to install a custom recovery. TWRP for the i747 is here, the top image is flashable with Odin while in download mode. Remember not to reboot from Odin. Instead remove the cable, pull the battery, then boot straight to recovery. Once you have TWRP loaded, boot into recovery and use the terminal emulator in it to determine bootloader and modem with these commands:
Code:
getprop ro.bootloader
getprop | grep version.baseband
Once you know the version of bootloader and modem you had been on, reflash that version from TWRP you will probably need the file on an external sdcard to do so. After this you can flash your rom of choice from TWRP, stock or otherwise. Since you were having imei issues go with one of enewman's stock roms, as @DocHoliday77 suggested. He can then help you with the imei issues if still necessary. Any other ideas Doc?

Ok, so
Bootloader = I747UCUEMJB
I don't get anything when running getprop | grep version.baseband in the recovery.
This is what I've done so far.
Booted w/ the sdcard trick (bootloader in the sdcard).
Installed twrp
Installed the following files:
AT&T_I747UCUEMJB.zip
d2att_I747UCUEMJB_bootloader.zip
d2att_I747UCUEMJB_modem.zip
d2att_Kernel_Stock_init.d_4_3_MJB_v1.0.zip
That brought the phone to life again (w/ stock 4.3). Then I flashed CM12 from the recovery. All went ok.
Problem is, I still don't have 3G connectivity, only edge.
What would you recommend try next?
Thank you

Alright, I was able to upgrade to UCUFNJ1 for both the bootloader and baseband. Still no 3G. Ideas?

Pm me. As I said before, if the imei is correct, I might be able to help. I can't do it here though because it's against forum rules to post the info publicly. (Too many people want it for illegal use).
When you pm me, include your current bootloader and baseband. (Just so I don't have to keep coming back here for reference). Also include how it was lost and if you know how it was restored.
I know you've already posted some of this, but I get lots of PM's so it'll help me keep track of everything without going back and forth between here and there.
Also, you need to be stock for this to work, so don't flash anything else just yet.
Glad to hear you got it running again BTW!

Alright, I'm happy to say that with the help of our fellow DocHoliday77 I was able to solve the issue !
Thanks everyone!

Glad you have it working.
Way to go Doc.

Damn japi2000. You did that quick good job.

Thank you!
I can't believe I went from a almost dead phone to a fully working one in only a few days, even with the 3G/4G working again !
This forum and people are amazing! Thank you!
