[Q] Backup Baseband Before Root - Galaxy S III Q&A, Help & Troubleshooting

Hi all,
Please could someone advise the best method to backup my unrooted baseband before I root.
I previously rooted my old s3 then accidently flashed the wrong stock fw onto it and broke it by upgrading the baseband so it couldn't get a singal, need to avoid this
Thanks in advance

I doubt that you can backup it without root, whereas you could note down your current one and just download it from general sections baseband thread.

[Q] Root gone with ICS upgrade

Hi, apologies if this has been covered but i couldn't find anything specific on this.
I got the ICS 4.0.3 upgrade yesterday for my S2, but my root access seems to have disappeared (upgrade was the official Voda UK upgrade via Kies). I originally followed the instructions on this forum to root the phone a few months ago. Titanium backup has stopped working
Presumably I need to re-root? If so, should I follow the identical instructions which I used for rooting my 2.3.5 version?
Cheers
Wat lp version is it? Just install cf root kernel and u should be fine. Or speed mod. Up to you.
Yes the same instructions, just make sure you root using a cf-root kernel for ICS

[Q] Galaxy S3 Firmware Update [how to]

hi,
I recently rooted my galaxy s3 with Odin, and installed a moded Rom.
today, I decided to go back to the stock rom, and restored my phone with a backup I made before installing this Rom.
-will the firmware update automatically in a rooted phone?
-my build number is I9300XXALE8. Should I update to a newer one? (androidromupdate[dot]com).
-can I do it withput Odin? (through the update/restore page)?
sorry if these questions were already answered...
and thank in advance.

[Q] how to install ICS old bootloader

Hello to everybody.
First of all I need to tell that this is my first post in this huge community, so as you could understand I am so totally noob, besides I am from Latin America so excuse me for my bad english.
I have a S3 I9300 (bought on december 2012) and I am feeling worry about the sudden death issue, according with what I've read one of the possible causes of this issue might be the bootloader of the jelly bean, so they recommend to install old bootloader the one which came with the ICS 4.0.4, but doing this may brick my device.
So my question is does worth the risk to install this old bootloader? another thing is that I have the red exclamation mark when the phone is booting (I am currently using Sotmax v12 rom with Yank555 2.8f kernel).
And in case the answer is yes do someone has tutorials or video of how this should be done?
Thanks in advance for your help

Thank you for your response, I've read the thread you suggest and I still do not understand some aspects like:
1.- Do I need to be on 4.0.4 Stock to flash the bootloader?
2.- In order to flash the bootloader just need to place the ICS old bootloader XXALEF provided in the thread in the bootloader section in Odin 3? or is needed to do another procedure first? do I lost root?
I am sorry to bother you, but I want to be sure about what I am going to do before try to do it.
Thanks
I think do what you see in the other thread.
The trick is look for a country that has not gotten uodated to JB 4.1.2. Stuck at 4.1.1. DL the last 4.04 (ICS) of that country. Flash it via Odin. Then upon first boot (dont root in the mean time) let it update to 4.1.1 via the phone's OTA Software Update. This is the key part when a JB 4.1.1 Bootloader will be installed that will break the XXELLA bootloader's protection.
After that OTA update is finished (285 MB file) then you can flash that XXALEF ICS Bootloader through PC Odin.
Then do root or wahteva you want.
This is described in Dr Love's thread. I'd done this way.
Another way is this one.

Thank you so much for your response. I will try the second method and see what happens.
Sorry for my persistence.
Now I understand almost every step on the procedure to downgrade the old bootloader, but one still question still remains do I need to be on 4.0.4 stock to downgrade or it does not matter what firmware I am using?
Thanks for your help

[Q] Do I need unroot to get stock rom?

Hello everybody
I am new in this forum so please don't hate.
I hade S3 with orginal branded system but it was very slow so i wanted to get orginal rom without branding. I gave my phone to my uncle and he roted it and instaled TWRP (teamwin), galaxy apps and namless rom. This rom is a custom room and it has a lot of problems like: sometimes camera isin't working, widgets are invisible, galaxy apps weren' working (so i made a mistake and deleted it and now other google apps like YT aren't working) and there are a lot of another bugs. I have Odin and orginal version of non branded system from SamMobile. My question is do I need to do unroot before pluging telephone to pc and using odin or this is unnessery? I am new in xda and I don't now much about programing and stuff like this. So please help me!!
I would not use the image file from SamMobile to repair this issue. If you give me your exact model and serial off the sticker under battery, I can get you the Service files you need to COMPLETELY fix your issues.
And NO, your not going to need to unroot the device if you use the Service Files. It will under it for you!
Please let me know!
You can just flash the same rom over it to repair it.
You can flash with odin but im not 100% about debranding. If the phone is unlocked you should be ok using a btu (international) rom.
Make sure you know your efs version if you plan on flashing anything less than 4.3.
The answer to your question is no. You do not need to unroot but you WIll lose root.
Sent from a stolen phone!
The best way is to tell your uncle to restore stock firmware debloated.
Otherwise,find out your baseband version and model number and search xda for the CORRECT rom and flash it using ODIN.
