downgrade baseband?

Hey guys... Looking for 2 answers...
Can the baseband of an M919 be downgraded?
If so, can you point me to a tutorial or Instructions?

It all depends. If you're still on the MDL bootloader you can Odin flash the MDL baseband. If you're already on the MK2 bootloader you can not go back.

Already bought unlock codes from FastGSM... so, no need to downgrade now... But, for reference... How do I know which bootloader Im on? or how would one preserve an old bootloader if updating a ROM

You will get the new bootloader if you a) took the OTA update or b) update via kies or c) Odin flashed the whole 4.3 firmware.
In Settings/More/About device, look at your baseband. The last 3 digit should be MDL or MK2.
That's your modem.
Bootloader you need to go into Download mode I believed.

To be honest, I've found the best thing to do is not jump on the band-wagon and flash an update until you research what the Devs suggest before flashing away. It has saved me a ton of grief and aggravation. They know these updates in and out. For instance, they were warning people to hold off on the MDL to MK2 because of the bootloader and KNOX issue but people didn't research and now some are having problems and it is too late, you can't go back. If you did the OTA update or through Kies you are stuck with MK2 and KNOX. For most people it's no big deal, but if you enjoy modding your phone it can be a pain in the rear.

Picked it up with the MK2... was trying to do a SIM UNLOCK without paying $30US (The IMEI unlock is $30, the USB/software unlock is $15... and the debug unlock is free...but it looks like the debug is done away with in MK2)...
Should have probably mentioned, this is a Metro PCS flashed with TMo rom (did that to try to get the debug menu to work correctly as there has been some luck with it)... Anyway, now the fun part of getting back to MPCS...
On a side note... you guys know about the Re-Partition flag in Odin? You guys here in XDA make it sound as if its a good way to brick a phone... in the MPCS forum (on a dif. site)... has that mark checked when flashing back to the MPCS rom (stock) from a TMo rom... any ideas?

If so the carrier that sold it to you HAS to give you the unlock code.

[Q] EZ-Unlock & friend bricked my phone, help needed

yes, take him outside and beat the crap out of him. Then take his money and go get a new phone.
Other than that, I don't know.

No I cannot, my friend(parklane79) and I actually found a method, it seems promising but i need to try it out first.
im not afforded the link rights yet but the title is "Fixing a bootloader-bricked Galaxy S3 using an SD card (Qualcomm SGS3 variants)" and a more simpler guide for n00bs(although not a complete n00b been doing this for a few years now :good: ) like myself, "[GUIDE]Unbrick a Hard Bricked SPRINT Galaxy S3 (Without JTAG)" but for the second guide you need to grab the i747 debrick.img off the first page of the first guide.

Yea tried with a class 10 16g micro sd like a million times and it wont work.and i think its because i dont have the 4.4.2 img if some one could help me out by uploading it. u et the img via busybox dd if=/dev/block/mmcblk0 of=/sdcard/backup.bin bs=1M count=70

So the phone won't power on at all? Can't get into download or recovery?

are you %100 certain it's the AT&T 4.3 debrick.img? did you put it on the SD card using win32diskimager?

And yes I did use win32diskimager. I tried once on linux mint but i believe the file corrupted so i just ended up using win32DM. I mean they are supposed to do the same thing, if im not mistaken

Then you should be able to use a debrick.img. are you using an sd card the same size as your phone's internal memory? if you had it on 4.4.2 then you might need a debrick.img from someone with the same phone on the same network running 4.4.2?

sounds like you're stuck until you get that .img file. If you know someone with the same phone you could maybe get them to install 4.4.2 and get the file from them? otherwise keep asking around or wait until 4.4.2 is released for the s3, which might take a while.

I did, it was on CM 10.2 when i had flashed improper bootloaders and bricked it. I used the sd card to install 4.3, unroot+ reset flash counter then took it out so it went back to bricked. My only fear is that they may some how get it into download mode instead of just replacing the board and see the warranty bit: 1 which isnt able to be reset as it is an e-fuse which is blown when you install firmware without knox.

im sending in it through bell mobility. it was a replacement phone that i paid the $150 deductable on and has a 90 warranty. I said it was having issues/defective so they sent an s4 as free replacement on the 90 day. I prefer it to be bricked to fit the defective description as well as to decrease the chances of them finding out i had messed with it, the only real sign being "warranty bit: 1" in red on the download screen. I did use odin to flash the current 4.3 stock that it has right now, and i might be able to get it to boot without the card if i flash the bootloaders some more despite having done it twice and the card still being required. Like i said though, i prefer it hard bricked and i've erased every sign other than warranty bit: 1 that i messed with it by installing stock, unrooting, and resetting flash counter.

[Bootloader Unlock Code] 4.3 "EZ Unlock

Need someone to verify this for me. It says here that you can use a program called "EZ Unlock" to unlock the bootloader on the Galaxy S 3.
Can someone verify if this app would unlock my GS3 bootloader? I'm on 4.3 so mine is updated unfortunately. I would just get the bootloader unlock code from Samsung but I don't have an international model, that's the only one they would give you the BL code for.
EXTRA CREDIT I heard rumor of something called a "golden backup" supposedly a backup that exist on the phone of the older version you upgraded from, anyone?

No joy there, I'm afraid. Ol' Sam knew what he was doing with the 4.3 bootloader thing and a BL with EZ Unlock is a No-No. I just tried it now and whilst the whole process went well enough, the outcome was a hard brick. It, therefore, doesn't seem possible to 'unlock' your bootloader, at least, not for now.
The 'golden backup' is an option you see in the service menu. Not sure what it does though.

Yeah. Just to see if there was any way I could add to the body of knowledge... I'm aware EZ Unlock works with older firmware versions of the VZW model. The instructions on the site, however, suggested it works with the i747 as well. Apparently, this must be with older firmware versions as well and not the 4.3. After powering off the phone following the process, the phone just wouldn't power back on again. At least, not until, I'd inserted my debrick card and done a firmware restore.
I know I've seen the golden back function when accessing the service menu via *#197328640#. Never had to use it though so I wouldn't know if it does back up from older firmware.

Well, your failure has become my knowledge lol. I'm still really interested in the learning about the "golden backup" though. I wonder if the Galaxy S4 unlock procedure would work for us? I may play around with it.

Honestly, I've read a lot of stickies but most of the OP's don't mention things supporting 4.3 or not, so it makes trying things out a little tougher. Is there a "back to stock" 4.3 guide? I assumed that's what you did when you bricked. Every 4.3 forum/guide I find is all like (4.3 beware this and beware that!) lol

Oh! I wouldn't risk "bricking" my phone if I wasn't reasonably sure I could recover. In fact, I've "intentionally" bricked this particular device in every way you can imagine just for learning purposes. I really think an unlock exploit is possible and we may be closer to one now than we know. Indeed I feel Touchwiz 4.3 has been unduly vilified because of the secure bootloader and other than the absence of a free unlock option, it's a major improvement on previous versions. I haven't seen the S4 unlock procedure. Can you send me a link to any thread on this?
There are a couple of threads dealing with recovery and return to stock for the 4.3. The first is a guide on how to recover from a hard brick caused by flashing the wrong bootloader. That was where I got my debrick file from ...

Yes, it should work - as long as you are not flashing a non-compatible bootloader. I noticed also from the development threads that someone has now put together an Odin flash-able image for 4.3

[Q] Accidentally Hard Bricked an S3

I was updating an s3 running cyanogenmod 10.2.1 to 11. I realized that the bootloader needed to be updated long story short i accidentally flashed the i9300 bootloader instead and now my phone is hard bricked. I heard about a method using the sd card to allow the phone to enter boot recovery so i could get into download mode could someone help me to do this?

The only fix that I personally know of is using a jtag service. If there is an sd card fix floating around out there, you'll need to search for it. If you fail, mobiletechvideos.com can help. Expect a week to 10 day turn around time

You are probably referring to the method posted in the thread below ....
http://forum.xda-developers.com/showthread.php?t=2549068
You have nothing to lose in giving it a try. Doubtful if it will work, however, since it is specifically for recovering from a brick caused by flashing an older bootloader after 4.3 upgrade. As BrianRay advised, when you have a brick caused by flashing a different model's bootloader, a JTag operation may be required.

Sadly, no, I don't. You could create one, however, if you know someone who has a similar device running 4.1.2. If you need further instructions on how to do this, you would need to contact the author of the original post. He is the expert there. A JTag may still be your best option, however.

Hey, try to get the phone into a download mode by using at USB jig. You can buy one for 3 bucks from ebay. If that doesnt do it, then you can go to the method of using the debrick image.
Once you exhaust all of these possibilities, then you can try the JTAG. But the Jtag service is expensive too. Good luck.

[Q] SGH-I737M - modem issues

Hi all,
I have a Bell Canada Samsung Galaxy S3 that I can't get the modem to work on. I have Philz recovery on it and have tried a few modem files but neither the wireless or the mobile carrier works.
I have tried putting cyanogenmod on it but am back on a stock ROM at this point. I am at a bit of a loss as to what to do.
The phone boots fine, looks all normal but I just can't get on the mobile network(tried multiple SIM's).
I am really hoping you can help!

Does your phone display the correct imei when you dial *#06#??

It does, it shows my IMEI with a /5 at the end.
At this point, I am running I747MVLUEMK5_I747MOYCEMK5_BMC
I also do show cellular signal but can't seem to connect. When I scan wireless networks, I pick nothing up.
Any ideas?
Thanks again!

Is the phone blacklisted?

I don't think so, how can I verify that? I did buy it used just over a year ago and it only broke about a month ago?

You've had the phone for a while so I didn't think it would be blacklisted.
Since you have the 4.3 bootloader, you need to have a compatible modem and, from my experience, only the mk5 modem will work.
Did you use Odin to flash back to stock?

Yes, that is how I put the current stock firmware on it. I had cyanogenmod on it at one point...

I am at a loss as to why you cannot connect to a network. Which carrier do you want to connect with?
