There is a debrick thread in Q&A that is often successful. Should work if the brick happened while flashing official firmware. Which did you flash exactly?

You may need to find a 4.4.2 debrick.img from an I747M. Pretty sure someone posted one at some point, but can't remember for sure. A 4.3 image might work, but it's entirely dependant on how successful the Odin flash was. If the bootloader got flashed, you'll have to use the 4 4.2 image.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] singhz905:
Yes, I was actually kinda looking into it. But I read somewhere that if Phone got bricked with flashing 4.4.2 then there is no going back So got kinda demoralised. I've searched various forums and non of the users have been successful. But will surely search again. Thanks for replying.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] DocHoliday77:
There have been some successful in debricking on 4.4.2. Its mostly only those that flashed a 4.4.2 modem on 4.3 firmware are unfixable.

This is my first attempt at a post, so please go easy on me if I don't get it done quite right.

I post this as a warning to anyone who might attempt to use Kies 3 to revert to factory firmware.

I recently started noodling with flashing ROMs, etc. Prior to that my device had received the AT&T OTA Kitkat. During my experimentation, I ended up with my I747 in a soft brick - VERY scary to a person new to this type of thing. Of the many things I tried in an attempt to regain functionality, one was to connect to Kies 3 and let it try to revert my device to stock ROM. I downloaded and installed the latest version of Kies 3 on my PC. When I started it and connected the device, in download mode, it recognized that my device was connected to my PC, recognized my model number and serial number, and said it could do a recovery. All seemed well, so I agreed to all the dire warnings and told Kies to proceed. After it finished, I discovered that Kies was flashing an older version of firmware (I don't recall which one, but older than KitKat). I should have paid more attention to the firmware version Kies said it was going to install, but I assumed (I know, I know) Samsung's own software would be smart enough to not push old software that would brick at device that AT&T already had updated to Kitkat (or does Samsung do the updates on behalf of AT&T?).

Fortunately the soft brick after Kies was no worse than the soft brick before Kies, but I still find it had to believe that Samsung's own Kies (version 3) program pushed an older version that could not work with the current, up-to-date OTA on my phone. I had just downloaded and installed Kies, for the purpose of this recovery, so Kies was up to date.

Again I post this as a warning to other noobies who might try to use Kies 3 to return to factory software.

Hey doc I'm tried to update to the cm12 alpha builds from cm11 and when I did ..my phone didn't recognize my sim. Someone suggested that I need to update my baseband to NF2. I'm currently on baseband i747MVLDMF1. I downloaded the NF2 file for rogers but I don't know how to install it. Can you please help ?

Yea i would like to know if i have to update the bootloader and if so then how ? ...and do I have to upgrade to a 5.0 ROM after updating the modem and bootloader ?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
No you don't have to update to 5.0 just because you updated bootloader & modem the last stock ota was kitkat all you have to do is flash the zip in recovery if you didn't take the ota from JB to KK you can upgrade to KK via Odin with the 4.4.2 tar. A lot of people just update the bootloader & modem by flashing the zip you downloaded. I took the stock ota so I didn't have to flash the zip. I don't think you have any worries, talk to some people in the 5.0 ROM threads I've seen a few with the same phone you have that have updated by flashing the zip. Read thru & ask around the cm12 threads there's like 3. All in all it's 5 or 6, 5.0 roms for our device! Good luck man!

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
[MENTION=5670416]bloodstorm666[/MENTION] I couldn't tell any difference MJB & NE4 but once I went to NJ1 I noticed my signal reception is much better, if you're on MJB then you were on 4.3 stock last, the 4.4.2 update would've changed it to NE4. I don't think you'll brick it by flashing NE4 just go to enewman17's files on android file host and get the MJB to NE4 update .zip from there that's where others & myself have had success?

Edit: oh yeah the .zip file should be around 19.8mb in size!

I think you can just flash NJ1, however I'm not 100% sure I've heard that you need to be on 4.4.2 OTA to flash NJ1 & I've also heard people say they flashed NE4 & then NJ1. I was on NE4 stock OTA when I went to NJ1, just ask enewman17 to be sure he really knows his stuff! If he says you're good then go for it!

Hi everyone,

Could someone help me to clarify something that I'm not yet 100% sure please:

I was given a cracked-screen SGH-I747M Canada.

Its original (and currently) rom is: I747MVLUFNH2 4.4.2 stock (bell or virgin). <=== NH2

Rooted and recovery:TWRP 2.8.x.x latest.

I don't have a mini-sim card yet (I will cut the standard sim to mini-sim). It's a Rogers's sim.

1) My question is: Can I "cross" flash this phone by flashing a stock Rogers' rom ?

Since I don't want to pay to provider-unlock (I don't even know if the phone provider-locked). Danger of bricking ?

2) And I also notice on the 1st page that the modem for Rogers is Not NH2, but VLUFNF2 (NF2)

Can I overwrite NH2 (current modem) with NF2 ?

Thank you everybody.

Device Type: d2can

Build Description: d2vl-user 4.4.2 KOT49H I747MVLUFNH2 release-keys

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cain05:
Sorry for being a noob here, but I just want to make sure I do this right. I'm running a Rogers S3 and the bootloader I have is I747MVLUEMK5 and the modem is I747MUMUEND3 and I'm running CM11 (4.4.4). Can I go ahead and apply the modem in this thread? If not, I'm assuming I have to update the bootloader first, but I can't seem to find a download to just the bootloader. The I747MVLUFNF2 download on sammobile looks like it's going to put my phone back to stock, which isn't what I want if I don't have to because I prefer to use CM11. Thanks in advance.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] thetenthday:
I updated to the the latest Telus NK2 image on sammobile recently in order to ensure I was running the latest bootloader/modem for lollipop (was having issues on the mid-2013 bootloader/modem combo I had been running - and flashable bootloaders don't seem to be posted anymore). What I did, was 1) backup apps and make nandroid, 2) flash sammobile NK2 image through ODIN, 3) boot phone directly into download mode again and flash TWRP recovery, 4) boot into TWRP and flash the lollipop rom/GAPPs/SuperSU, 5) boot-up lollipop (first boot is sloooow) and restore apps. I got stuck in a boot loop at step 3 if I tried to actually boot back into the stock 4.4.2 rom, which is apparently fixed by wiping the internal card (something I was trying to avoid), but I was able to get around it just by flashing TWRP. Good luck if you go this route. I was ready to lose my phone to a brick, if needed, given all the caution about upgrading to recent bootloaders but thankfully it all worked out.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cain05:
I was considering flashing the stock rom, but I seem to recall reading somewhere about the bootloader being locked with the recent updates. If that's the case, I think I'll just stick with what I have until something doesn't work and I have no choice but to try and upgrade. I don't think I'll be using a L build any time soon since there's problems with the camera, among other things.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Is it locked or are we just not able to downgrade.

I thought a locked bootloader referred to being unable to root and/or install unsigned packages.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] cain05:
I believe a locked bootloader prevents you from installing stuff like CWM, which would then prevent me from going into recovery and loading CM11 back on after upgrading to stock. All I want to do is make sure my bootloader and modem are the latest versions. If I can flash the firmware from sammobile then restore my CM11 install from a backup made in CWM that's all I need. I can't risking bricking my phone, which is why I'm trying to figure this out beforehand. :)

Baseband VLUFNH2

Things are working fine, however there have been a few times when I've experienced a loss of mobile data despite having a strong signal. It would work in one part of the city then an hour later in another part, I'd have no data.

I'm now wondering if I need to upgrade the modem?

I see from this thread that there are two versions for Bell: VLUFNE6 and VLUFNH2

Which one is newer? Do I need to upgrade the modem?

No SIM error

Hey everyone:

I've been following this thread (and others like it) religiously for the last week, trying to solve a problem, but it is still hounding me, so I would like to see if anyone has any new ideas that I have not tried yet.

Situation: No SIM, not registered on network error

History/highlights:

- Samsung Galaxy S3 SGH-I747M Canada, SaskTel network locked.

- wanted to get the thing unlocked, so went to retailer and was willing to pay the $$$, but they couldn't get it unlocked.

- while trying, I copied the unlock code

- I believe it didn't work because I was messing with the installs, I had / have the following in my bootloader info which I believe is due to my messing with the OS.

Warranty Bit: 1

BOOTLOADER RP SWREV: 2

- I understand this implies bootloader is locked and there is nothing I can do about it, because this is post 4.3 with the knox implementation.

- currently knox doesn't work.

- Since I believe I have the actual unlock code needed, all I want to do is get back to working stock so that I can apply it.

- have applied new OS (4.4.2) via Kies and Odin numerous times, worked every time but continues to display No SIM error.

- have tried hardware fixes (paper behind SIM card, etc.) and software suggestions from numerous threads and nothing worked. I have 3 SIM cards from different networks and none of them are recognized (not even the original SIM card that was recognized when I took the phone to get it unlocked in the first place,) so the problem isn't the SIM card.

- I highly suspect it's OS/MODEM/bootloader related.

- OS/MODEM versions match, and currently installed is version I747MVLUFNH2 but immediately after install, updates itself to version VLUFOB1

- when installing new tar with odin, the modem file gets installed.

- have tried manually applying Sasktel_GalaxyS3_VLUFNH2_Modem.zip at same time (in PHONE data field of Oden) as OS (I747MVLUFNH2_I747MOYCFNH2_I747MVLUFNH2_HOME.tar.md5) but unsuccessful, but it's possible I messed up there.

Any thoughts?

As I say, I just want to get back to a stock, working (and locked, assumed) OS so that I can apply this unlock key.

Thanks a lot,

Bill

Could someone help me on how to fix the IMEI of my phone? it is null and it always says that simcard is not detected. after flashing a custom ROM, the developer said that it is because of the updater script on the meta-inf folder.

Which ROM is on the phone? Is the phone an i747 or i747m? Which bootloader version and modem are on the phone?

These things are important to know before flashing any bootloader or modem because an incompatible modem and bootloader combination could brick the phone.
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] padong23:
I'm sorry, but i hope that you don't feel angry on me, because i think i posted on a wrong thread, my phone is Alcatel onetouch pop d5 5038a. I successfully flashed the Rom, the only problem is it can't detect my sim card. It says sim card is not detected.

The Rom i flashed is Dexiotites Rom
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] audit13:
Sounds to me like the ROM doesn't support the bootloader and modem currently installed on your Alcatel. I recommend flashing back to a stock ROM and check for over-the-air updates to see if there are updated modems or bootloaders for your phone.

I'm on the NE4 bootloader. Can I mobil odin to the NJ1 modem and be okay?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
Once you have reached the NE4 bootloader and modem you should always keep the modem and bootloader at the same version. If you upgrade your modem to NJ1, upgrade your bootloader to NJ1 at the same time. Not doing so has caused bricked devices for many. And do not downgrade either bootloader or modem from here on out.

I have an S3 with 4.4.2 stock NJ1 ROM and bootloader with "null IMEI" and unknown baseband. Is there a way to fix it by flashing back to NE4 using Odin, or reflashing the NJ1 radio?
[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] dawgdoc:
If you have the NJ1 bootloader Do Not flash back to NE4. You will brick.

Being on NJ1 it would be safe to flash the same modem. The safest thing would be flashing the NJ1 bootloader/modem combination file. I have seen download links in several threads started by enewman17. At the moment I don't recall if any were Odin flashable. All I am sure about are the ones flashable from a custom recovery like TWRP. (Found in the OP of the other thread you posted to.)

[AT&T, Rogers, Bell, Telus Samsung Galaxy S III] canodroid15:
Don't flash NE4 if you're already on NJ1. that would be a downgrade. NJ2 is the latest & a step up from NJ1. Read back a few posts above your last 2 posts. You can find the NJ2 bootloader & modem combo zip by searching enewman17's threads. Download the phone info app from play store to be sure your current bootloader & modem match before going any further. If both bootloader & modem are NJ1, then simply flash NJ2 combo zip in TWRP recovery & reboot. Be sure to take the correct steps as there is risk involved any time you update firmware. Especially on d2att. Good luck!
