[Q] Is possible to download from 4.1.2 to 4.1.1?

Hi,
I am newbie for Android and this could be silly question.
Is possible for me to downgrade from 4.1.2 to 4.1.1 with original stock rom (international version N7100) and no root?
If possible, could you write down steps that I need to take?
Yes, I did search the forum but it doesn't comes with step by steps?
Reason is battery drain too fast especially at night.

I had the same problem... You must be rooted first to do it...
Download the correct firmware (http://www.sammobile.com/firmware/)
Install MobileOdin (https://play.google.com/store/apps/details?id=eu.chainfire.mobileodin.pro&hl=en_
Copy the tar.md5 file to your external sd card
Open Mobile Odin and flash the stock rom. It even has an option to root it without effecting the status. My phone is rooted but it still says official. Then use TriangleAway to reset the counter to 0 and you're good to go.

You dont believe you have to be rooted at all, I did this last night, the way I did it was went into stock recovery, factory reset and wiped cache, rebooted, turned off, booted into download mode, connected to pc, opened odin and flashed stock 4.1.1 simple as. It did get stuck once on samsung logo I left it for about 10-15 mins, went back into recovery and wiped and factory reset again, rebooted and all was good and now Im back on 4.1.1 so far its been off charge for 3 hours or so and its only gone down 1% it would have been around 8-10% on 4.1.2 for me
I wasnt rooted before, was on stock 4.1.1 then upgraded to 4.1.2

Absolutely possible. I just did. Steps are,
1- Make a batch backup with Titanium first, on your 4.1.2 ROM.
2- Flash the stock 4.1.1 ROM via Odin.
3- Root it.
4- Go to recovery and wipe data, factory reset, wipe cache partition, wipe dalvik cache.
5- Now you've 4.1.1 fresh ROM, install Titanium and restore all missing apps and system data.
6- Now you've a fresh 4.1.1 ROM with all the data and apps.

Jujuburi said absolutely correct, why you need root to simply flash stock rom.
Just to add.
After downgrading as described by jujuburi above, your device still will have new bootloader and that won't downgrade by procedure said above and so you have to re root with cf auto root or one of the CWM recovery, exynose abuse apk won't work.
Downgrading bootloader is needs different method and no need to describe here as it is not recommended/required at all.

The easiest way to do it without a pc or raising your flash counter is to follow my tutorial.

Okay, that mean if I dont root is 100% i cannot downgrade it to 4.1.1?

It's only a temporary root. Once you load the tar.md5 in mobile odin you have the option to keep it rooted or not. Just simply keep the box unchecked and you'll be good to go. If you're not rooted right now root it with cf-autoroot to keep your status as official on 4.1.2 then install mobile odin and finish the steps.

????? Your guide isn't the easiet way at all. The OP didn't say he didn't have access to a pc? And flashing stock roms via odin doesn't raise flash counter afaik?
Also your link to odin is a paid for version which isn't required.

+1
Absolutely right
-No root needed to flash using Odin, neither flashing stock ROM with PC odin raise flash counter.

hi guys
a have the same sleep drain issue with 4.1.2 and going to odin flash 4.1.1 but do i have to wipe data/cache ? and if so do i have to wipe b4 or after the flash ?? thx

It is not compulsory, but in many cases during downgrading, after flashing ROM device may gets bootloop OR stuck at samsung logo. in such caes you need to do it.
But i do prefer wipe always after flashing ROM for better performance, you can do it after flashing.

pls clear the confusion..
Hello all,
I have been reading, viewing videos etc for past 4 days. and have asked questions on youtube to people but no one replied now you are my BIG HOPE..
i have an international version unrooted galaxy note 2. I dont have much details about baseband etc as i never jotted them down before upgrading. But i do have details now after upgrading to 4.1.2.
Baseband- N7100XXDLK7
Kernal 3.0.31-679347

SMP PREEMPT Wed Dec 26 10:26:20 KST 2012
Build Number
JZO54K.N7100XXDLL7
AP: N7100XXDLL7
CP: N7100XXDLK7
CSC: N7100DBTDLL2 (which is germany)
I am downloading N7100XXALJ3 N7100DBTALJ2 from dr.ketans N7100 all in 1 old rom posts of 4.1.1 Oct 2012 as thats what i cuold find for DBT germany firmwares. Is that right one........???????????????????????
like others i upgraded to 4.1.2 and have been facing battery drain problem. first of should i wait till samsung comes up with fix in next update or shuld i revert back to 4.1.1.
I read this post as and it is so confusing-
Battery only lasts 1 day so want to go back to stock firmware 4.1.1 and want flash counter zero and everything legit. one member said root is needed then other said its not. then dr. ketan in the end say just to go back to stock root is not needed and just flash with odin and it wont increase counter as well if flashed with odin pc. is that right that we dont need root to just go back to stock 4.1.1 as he said.?
---------- Post added at 09:44 PM ---------- Previous post was at 09:24 PM ----------
Now i am confused as i have multiple options suggested by all in this thread--
* If root is not needed should i just download 4.1.1 (enquired about the firmware N7100XXALJ3 N7100DBTALJ2) and flash it with pc odin just like bradmax 57 said and keep it all legit and will i still get OTA samsung kies updates in future..?
OR
* Should i root my phone first using cf-auto root with method given in your N7100 all in 1 forum and then flash 4.1.1 with mobile odin and then remove triangle away once and for all.? if we go this way obviously phone will be have full root access with limitation of not being able to flash zip files from pc (but will be ok with mobile odin for that) and cant use nandroid backup and restore - i am not fussed about these things but want my phone to be legit for warranty and do need future updates OTA and from kies.?
Also do i wipe cache, factory reset from recovery before or after flashing 4.1.1 as bradmax57 had to do it twice before flashing as it was getting stuck at samsung logo but on the other hand dr.ketan suggests to do it after flashing 4.1.1..
Kindly help.
Thanks in advance for your precious time.

Here i giving clear answer and you should not have any confusion.
-No need to have root to flash 4.1.1 with Odin
-after flashing, you may stuck at samsung logo, in that case you have to reboot to recovery and have to wipe cache and data
-I don't recommend to downgrade, as latest 4.1.2 having SDS fix, on 4.1.1 you device can be brick without any reason. if you have battery issue, download latest MA6 ROM , not necessary you will have to flash DBT ROM, you can flash any country ROM and whenever your country get same update, same way you can flash that ROM with Odin.

First off a big big thank you to dr.ketan, mazdamiata and jujuburi who assisted me and cleared confusion. I have down graded to 4.1.1 easily and see a massive battery difference already. All i had to do was download stock firmware for my phone csc region and flash it with odin. wipe data , cache in recovery mode as it did get stuck on samsung logo and its all good. no root needed and flash counter etc remains untouched as well..

So you're saying we can flash a different rom to our phones without it breaking? I find that hard to believe. Why would there be different firmwares then from samsung? I need TTT firmwares, so I could flash any DMA6 firmware since mine isn't available yet?

dr.ketan said csc doesnt matter. if we flash rom of different country. the rom has kernal, csc information. the only thing is we will get ota or kies update of that country whose rom we flash. rest i wouldnt know lets wait for a word from dr. ketan or some one on this

You can flash any ROM of N7100 to your N7100, that is that simple.
I never seen a case of bricking by just flashing stock ROM. just selecting own country ROM will help you for better language support, and some priority/selection of application for your country on play store when you search OR google suggest you. You can flash any country ROM which is latest and still not available for your country.

d2tmo(SGH-T999v) Bootloader and Baseband version

I'm looking to see if i'm all up to date. I have the T999V version. I do a lot a search, without being 100% sure if I have the latest version of the bootloader and baseband for my phone.
Is someone knows what are the last version ?
My current are:
Bootloader: T999VVLDLL1
Baseband: T999VVLUEML2

All the modems are listed in this comprehensive thread. I don't know if you are on Wind or Mobilicity.

I aware of that thread, but it's only for modem(baseband) but not bootloader
I'm looking to find a solution for newer rom that won't boot since cyanongenmod merge s3 variant together to d2lte
Some people seems able to boot, and some like me can't
Maybe it's just cause by older bootloader like mine (VLDLL1 for SGH-T999V)
Sent from my SGH-T999 using xda app-developers app

The newest bootloader for your device is ML2
Sent from my SGH-T999 using Tapatalk

If you want to be up to date with T999V phone valid for everyone, stock rom, any custom rom. doesn't matter, work for any scenarios.
Most up to date file by 2014/03/03
You'll need this:
Odin 3.07
T999VVLUEML2_T999VYVLEML2_T999VVLUEML2_HOME.tar.md5
UPDATE-SuperSU-v1.93.zip
philz_touch_6.19.3-d2lte.tar.md5
DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V1.1.zip
DE-SAMSUNGNIZER_SCRIPT_V5.0.0.zip Optional ( to remove lot of samsung crap if you stick with Stock T999VVLUEML2_T999VYVLEML2_VTR )
You have to be in download mode, hold HOME+VOL_DOWN+POWER)
Then connect with USB
Now with the PDA button in Odin, select the tar file in VTR-T999VVLUEML2-20140104101338.zip and Install
Then install philz_touch_6.19.3-d2lte.tar.md5 ( or any other recovery in tar file ) Like the rom, use the PDA button to install it.
Now reboot you phone in recovery( hold HOME+POWER+VOL_UP )
In the recovery, install UPDATE-SuperSU-v1.93.zip and DE-SAMSUNGNIZER_KNOX_REMOVAL_SCRIPT_V1.1.zip ( if you want to get root acces and remove knox new samsung securty)
Optional install DE-SAMSUNGNIZER_SCRIPT_V5.0.0.zip
Reboot
And now you have the latest Bootloader and Modem(baseband), rooted and without Knox for T999V and can install any other roms you want.

[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.

Thanks for the response, Stoney :good:
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!

[Q] Update Baseband - From M919Uvufnk2 To M919Uvufoh3

Hi,
Am on CM12.1, T-Mobile Galaxy S4 SGH-M919, Rooted, Android 5.1.1
How i can update the Baseband - From M919Uvufnk2 To M919Uvufoh3 using TWRP?

You can't. You have to use Odin.

Ok, i can use ODIN. But from where i can find the baseband for rooted custom ROM (CM) SGH-M919?

My method...Backup your current rom. Odin the oh3 stock release, odin cf root, odin twrp, backup the new stock rom, restore prior backup.

Hmmm...thats what i am actually thinking as of now....but looking for easy alternative like if we get the flashable zip or something of this baseband i can just flash it without taking backup of ROM and reinstall the ROM etc.....
But am looking for a site where i can download these basebands....

i take it you are trying to update the modem/baseband ihere you go. Must be done thru odin.
http://forum.xda-developers.com/galaxy-s4-tmobile/general/foh3-modem-bin-mdl-bootloader-t3191094
IMPORTANT: DO NOT CHANGE THE BOOTLOADER unless u KNOW EXACLY what you are doing...changing bootloader to the wrong bootloader will brick your device and some modem packages conatin bootloader. so make sure that you are getting a ODIN file that only contains the modems and no bootloader!
if you wish to properly update the bootlaoder and baseband properly ....just ODIN the OFFICIAL samsung release for your device and then re-root and reinstall recovery and then your rom.

Perfect....I will use this one....

And on S4 you don't even need to root before flashing TWRP and your ROM of choice. Just double flash the stock release with ODIN, let it boot up and make sure all is well, go into Camera to let it see if it needs a firmware update (happens automatically first time you run stock camera app), and when satisfied your phone is good, go into download mode, take TWRP + whatever else you want.

Modem / Kernel / IMEI / Stock rom 4.4.2

I'm using note 2 stock rom version 4.1.2 baseband DXDLK7 but I flashed DXDLK5 to fix problem about SOS Call only , the problem is when I flash stock rom 4.3 or 4.4.2 I got SOS only problem again and I stuck in 4.1.2 forever . I flashed modem MJ9 but still not work , and all modem download link in this forum died since hotfile server down . All new custom rom such as lolipop and marshmallow require baseband modem XXUFND3 but i can't go to that modem because SOS Call problem . So how can I fix this problem ? Thanks

Make EFS backup and then:
Download firmware from sammobile for your device i.e. N7100.
Install 7zip to extract it and copy SBOOT. and modem, then use 7zip again and pack (*.tar) those files separately, so you will have sboot.tar and modem.tar
sboot is the bootloader and modem is...modem.
Use Odin to flash modem and bootloader in download mode, then use also Odin to flash TWRP.
Then go to recovery mode and install your ROM using instructions in ROM thread (1st post).
You have to know that stock ROMs are identified by letters and numbers, the newest is probably OE1, I used bootloader and modem from French ROM.
