Downgrade from 4.3 to 4.1.2

My phone have
Custom Binary count: No.
Device status: Official.
In the setting>about device>status>device status:Normal. Now, I'm getting on 4.1.2 from MJ5 4.3. I used the followings
1. flash the respective official 4.1.2 firmware from sammobile.com. after finish flashing , go to recovery mode and wipe data.
2. flash Philz recovery via Odin.
3. install updated 4.1.2 modem (XXDME4 / DXDMF1 / DDMG1) from http://forum.xda-developers.com/showthread.php?t=2044937 via CWM (at this step you should get IMEI back.)
4. root the device with CF-auto root.(CF-Auto-Root-t03g-t03gxx-gtn7100.tar)
5. install Triangle away to reset flash counter.
6. full unroot super SU
7. wipe all data/factory reset .
Check the device status in setting. And then go to download mode to check again.
I'm not sure is this steps working on every Galaxy note 2 N7100. But actually I've been downgraded to 4.1.2 and I can get OTA also (already checked).
I decided to downgrade my N7100 because most of the custom roms use high RAM usage.
When at the firmware upgrade fail status,
1. Just flash "Philz recovery" via Odin.
2. After finished, Long press Vol up + Home + Power button to get into recovery mode.
3. Choose Wipe data/factory reset and "CLEAN TO IN STALL NEW ROM"
All of this step finished, Go to download mode "Vol down + Home + Power button" and flash the firmware (4.3 or 4.1.2 again).
NOTICE.
Dear all,
The latest 4.3 official firmware (MK4 or later ) has KNOX enabled bootloader and can't be downgrade. So, don't try to downgrade If your bootloader is KNOX enabled.

Remove KNOX bootloader to return to stock - using Dr. Ketan Method
Hi Guys,
I just want you opinion before i do this step. Hence asking
KNOX enabled boot loader has messed up my idea of return to Stock either via KIES or via ODIN.
I flashed the official Indian 4.3 ROM on my EU model NOTE 2 over the leaked ROM with MJ5 and it failed. I couldn't recover the phone with KIES either.
KIES will say that firmware update / emergency recovery has encounterd an error.
ODIN says FAIL and "Device Unsupported" appears in Download screen.
Shall i try Dr. Ketan's KNOX bootloader removal method to get my mobile back ? ( http://forum.xda-developers.com/showthread.php?t=2500823 )
Can i then flash the original firmware N7100XXDMF1 on my Note 2 (EU version) ?
Would appreciate if you guys could help me on this.
I can still access the download mode with KNOX boot loader.
Thanks

I am using Indian 4.3 rom on my EU device (N7100 Note 2)
It use Know enabled Bootloader.
* When I try to flash MJ5 bootloader with Odin, it failed. (incorrect version)
* When I try to flash EU 4.1.2 rom with Odin, it failed. (incorrect version)
Is there a way to downgrade to EU 4.1.2 rom? I guess NO

Same problem here
I flashed the 4.3 indian version. After 40 minutes it doesn't finished and my laptop battery is discharged. When i switch on the phone, it shows me the message error "firmware upgrade encountered".
Kies doesn't work.
I'm not able to enter in the recovery mode. I'm able to enter in the download mode. If i try to flash the rom again with odin, it shows me this error:
Any suggestion? thanks

flash recovery thru odin then maybe restore a nand backup or flash the new rom via cwm

So is there some other here already tried this step and got success??? please post location and if your from custom rom or from official rom? thanks

I'm able to flash the recovery thru odin, just do it and now i'm able to boot in recovery mode.
But i'm not able to flash the new rom via cwm because i'm not able to mount the sd card (it works only as usb storage, not as sd card mode and so i'm not able to upload the rom file on it).
I can find a solution for this, but i'm not sure it will work because now i have the knox firmware (warranty bit 1) and it isn't downgradable. Am i right?
thanks

I had to restore my efs data in order to downgrade back to 4.1.2.

I don't recall the exact steps, but I flashed my old 4.1.2 stock rom through philz recovery then ran the efs restore through dr. Ketans multi tool. Before the efs restore I would get boot loops at the Samsung logo.

Please Help Very Frustrated.

hello guys,
i bought a used galaxy s5 from someone running Poland Android lollipop 5.0 and it shows the model as SM-G900F When i try to root it with CF-Auto-Root-klte-kltedx-smg900f It gets stuck on the boot screen saying
"1. RECOVERY BOOTING (in blue),
2. RECOVERY IS NOT SEANDROID ENFORCING (red)
3. Set Warranty Bit: recovery (yellow)"
i googled alot and flashed Phillz recovery which removed the error above but when i go to recovery its the stock recovery? .... I cant install twrp-2.8.7.0-klte.img.tar Either because after flashing it when i go to recovery its stock recovery again. Activation lock is off, SE for Android status is "enforing" does this mean this phone has a locked bootloader? Maybe this phone was on At&T, Sprint or Verizon and the last owner flashed 900f firmware on it to make it look carrier free but it maybe a carrier phoone? Please help me i am very very frustrated right now. i dont even know what recovery is seandroid enforcing means.....:crying::crying::crying:

Ok guys, try this.
1. Download philz kernel that matches your modem number. I think philz_touch_6.26.6-klte.tar.md5 works good.
2. Put it in ODIN on PDA/AP
3. Uncheck "Auto Reboot" and make sure Re-Partition is NOT CHECKED (keep F. Reset time)
4. Flash
5. It will say RESET on Odin and nothing further when it is done so just wait 2-3 minutes when RESET appears to be entirely sure that the procedure is done.
6. Pull out phones battery.
7. Put it back in and now go into Recovery directly (Vol up+home+power)
8. ???
9. Profit
Hopefully this might work, i think i did the same

You need to just boot into download mode (voldown+home+power) then push volup to enter download mode
Use Odin to flash trwp 2.8.6.0 tar file in AP spot
Download a pre rooted rom of your choice for g900f
Place on sd card
Reboot to twrp by holding volup+home+power immediately during start of boot
Flash the rom you just downloaded
Now you'll be rooted
(That's what I did in order to get my phone rooted after installing the newest stock lollipop ota)

select install zip and flash the supersu.zip
then reboot it,after the first boot then go to the recovery and
install your custom rom

I followed instructions given earlier to install philz recovery, i opened it by booting into it immediately i selected format for new rom install. after that i am stuck on samsung logo i think the old rom is now deleted. Now i am downloading fresh 5.0.2 UK from sammobile i will download it and try to root it normally with flashing CF ROOT via odin. if it does not work then i will do what u guys said. I dont know if TWRP will work by the same method (booting immediately into recovery) but philz recovery did. And i will also try flashing a prerooted Rom. What i dont understand is that why is this happening in the first place? i had an alpha before i could enter into TWRP normally i rooted it with CF AUTO root normally...no errors or anything why is this happening on my S5? the last owner must have done something weird with it ...i am trying to figure out why is this happening in the first place. Appreciate ur feedback.

I also dont know why this is happening
and yeah
i had all the galaxy S series upto S5 and this the only device that is not rooting with CF-auto root
the latest updates from samsung may have done something i dnt knw
and eralier mentioned method worked 100% for me and i did root my device like that
And last owner may b or may not done anything with it because my device is a brand new and still i had that issue

SM-N910F > Bootloop // ROM Problems || Please Help

So.. hello.
Normally I don't come to forums to get help... but yeah. This is kinda bad.
I've got a little situation here.
I got my new Samsung Galaxy Note 4 (SM-N910F).
It was delivered with Stock 5.1.1.
First try:
I booted to the Downloader, fired up Odin, let it download the Autoroot.
Then I've got a bootloop.
Second try:
Booted into the Downloader, fired up Odin, let it install the 5.0.1 Stock ROM (Ending with 'BOB4')
It booted normally , then two things pop up constantly:
Something like "phone.xxxxxxxx.xxx Service crashed".
and "NFC crashed."
So I can't even unlock that phone.
Third try:
Booted into the Downloader, fired up Odin, let it install "N910FXXU1COI3_DevBase_alexndr".
Ended up in a Bootloop.
Then I tried to install the Bootloader aswell as the Modem and the Kernel, which are also in alexndr's Thread.
Ended up in the same Situation as the second try.
I don't no what to do anymore.
I'd really love to hear some help from you guys.

The third attempt was incorrect, that file is to be flashed from a custom recovery.
The second try might be because you did a dirty flash (Need to wipe data)
The first attempt boot-looped because in order to root in 5.1.1 you need a rootable kernel and the latest SuperSU (Not CF-Auto root)(Kernel is found in the Android Development thread)

What can I do to get a correct working System back? (Theoretically, I got time and bandwidth.)

I've already tried to flash TWRP via Odin, but I've never seen it.
Flashed recovery was for trltexx.
Getting to Recovery should be the same as getting to Download Mode, or?
Anyways. Will try it with tbltetmo and report back.
// Just installed the tbltetmo.
// Can't see how to get into the recovery.
// Am I missing something?

Update:
Just signed up at sammobile and downloaded the BOB6 (4.4 i think) for T-Mobile.
Flashed via Odin.
Seems like it does work again.
Currently its installing like 260 Apps.
Let's see.
// Edit: Nah. It got even worse.
// But I got a Recovery. So that's something.
IT ****ING WORKS NOW
Went into the recovery and cleared cache and data. (Kinda stupid I did not do it inb4)

Do a clean install in Odin. Since it came with stock android 5.1.1, then flash the 5.1.1 stock firmware in Odin. If you have a locked device of a specific carrier it will be even better to use the firmware made for that carrier only. And check the "Nand erase all" option in odin before hitting the start button to flash. That will erase all the data from ur phone and will do a clean install. Your phone must then boot normally. Also note that android 5.0 root file may not work for 5.1. Also check the model number before flashing.

Really old modem and bootloader, what are my options from here?

It's been a while since I've flashed anything; at least a year, though more likely two. Whatever I have now I'm guessing is a rom called stock(ish)v06, since that's what is listed in my bootloader. I guess the modem (baseband?) is NAE, and I'm still using a very old version of TWRP (2.6.3 according to my signature, haven't checked).
Obviously, the development that still exists for this device has moved well past me. But given how temperamental my device has been lately, I want to give flashing something newer a shot before buying a new device.
Trouble is, I'm not sure how to go about flashing roms and finding the right modem/firmware when everything I have is so out of date.
Suggestions?

I guess the modem (baseband?) is NAE, and I'm still using a very old version of TWRP (2.6.3 according to my signature, haven't checked).
Obviously, the development that still exists for this device has moved well past me. But given how temperamental my device has been lately, I want to give flashing something newer a shot before buying a new device.
Trouble is, I'm not sure how to go about flashing roms and finding the right modem/firmware when everything I have is so out of date.
Suggestions?

Download latest fully stock firmware so you will have latest bootloader and modem from http://www.sammobile.com
which is Lollipop, then flash latest TWRP. If you like stock, there is a stock deodex ROM, there is the awesome Wicked X (heavily modified Lollipop stock), or if stock is not your thing you can get CM12(Lollipop) or CM13 official(Marshmallow)

I want to make sure I understand what you're telling me to do, so a few clarifying questions:
1) I am meant to be updating TWRP first, then using it to flash stock firmware to update the bootloader and modem, and then flashing a rom of my choosing?
2) Why is that method preferable to using Odin to update the modem?
3) If I flash this newer official firmware, am I going to lose root?
4) In flashing the newer firmware, won't my bootloader lock, making it not possible to flash a new rom?

1) No, use Odin to flash full stock that you downloaded from sammobile.com, you cannot flash full stock from recovery.
2) Because some if not most newer ROMs require you to be on Lollipop bootloader.
3) Yes you will lose root, but this flashing of stock firmware is to update your bootloader and modem so you can flash the newest ROMs. The lack of root doesn't matter since you will be flashing latest TWRP via Odin and modified ROMs soon after.
4) if you have Sprint L720 the bootloader isn't locked. Check I'm 'about phone' to make sure you have an L720 and not another variant of S4
Make sure Samsung drivers are installed on your computer.
So your flashing steps go as follows:
1) Download everything you need first:
a) Full stock from http://www.sammobile.com to your computer
b) Latest TWRP tar file to your computer
c) The custom ROM of your choice (and correct gapps if AOSP or CM based) saved on external SD card on your phone since it will be flashed via recovery.
2) Turn phone off completely. I pull the battery then put it back in then boot directly to download mode: power + volume down. (Rebooting to download mode doesn't always allow a proper flashing)
3) Start Odin (uncheck reboot and reset time) and then plug phone into computer.
4) If COM lights up green in Odin click AP and select the file you downloaded from sammobile (it will be PDA instead of AP if you are using an older version of Odin) and click OK or start (I don't remember which it has)
5) If it flashes successfully pull the battery and then put it back in and turn the phone on normally. It will take a while to boot, like 15-20 minutes possibly. Flashing stock myself I have seen it say it was successful and it wasn't and the fix for me was to leave reset checked and let it do it's thing.
6) Once you have booted into your newly flashed stock OK3, do step 2 and 3 again, so you can flash TWRP.
7) When you go to flash TWRP in Odin uncheck reset time and DEFINITELY have reset unchecked (if Odin reboots your phone TWRP doesn't stick). Do step 4 again except this time select the TWRP tar file. Once it flashes successfully pull battery put it back in and boot directly to recovery (power + volume up) from there do a backup if you want, if not you can flash the custom ROM and gapps if necessary that you downloaded earlier.

Thanks for the very detailed response. This totally clears up my questions. I'll charge my phone this evening and give it a shot in the morning when my battery is at 100%. :good:

Help recovering data

So I have a friend who decided to mess with his phone, of course without doing a backup, and now he's stuck in a situation that it can't boot even into recovery.
Currently all I see when booting to recovery:
Recovery Booting. . . . .
Set Warranty Bit : recovery
The phone is G900F
He has no idea what version was installed on it before.
I don't need the phone to boot, I need to recover the files on it.
Being a oneplus person myself, I'm not that familiar with samsung phones (my latest samsung was s2).
I've tried to install with odin (3.0.7 - if that matters) the following recoveries:
official twrp 2.8.7
twrp
cwm
All these recoveries showed "Recovery is not seandroid enforcing" message as well as the above when trying to boot into recoveries.
I've tried the official recovery as well:
https://forum.xda-developers.com/galaxy-s5/general/sm-g900f-stock-recovery-5-0-lollipop-t3228871
which removed the "seandroid" message, but that's all.
Not sure what I'm missing.
Any help would be appreciated!

Hmm...
I see that your friend messed up his phone very well .....
Hopefully the eMMC memory is not corrupted becuase then only motherboard replacement would be necessary.
Summarising what you wrote:
1. you flashed "official recovery 2.8.7" -> where did you get it from? 2.8.7 is the very old version!
2. you flashed unofficial TWRP very old (2014) recovery (I checked your link)
3. you flashed unofficial CWM very old (2014) recovery (I checked your link)
4. finally you flashed stock, from old OS 5.0 Lollipop recovery provided from entrusted source - nobody reported that it works in the thread.
I listed this for you in order to underline one thing - READ, READ, READ, ASK, ASK, ASK .... before flashing anything to the phone and tell it to your friend.
Le's start with flashing from ODIN ver 3.12.7 (I am using it) this version of TWRP:
twrp-3.1.1-0-klte.img.tar for G900F which is the latest official recovery:
https://twrp.me/samsung/samsunggalaxys5qualcomm.html
Read how to flash it with odin method (when you open the link).
Edit: Are you sure the phone is SM-G900F? Please check model number on the label under battery (inside the phone).
Edit2: When you enter odin mode check phone model version as well - it is provided by installed bootloader.

First, thank you for trying to help me!
Please see attachments:
https://drive.google.com/folderview?id=1euC7-CoBeeUQxTGXQnPPgRE2-5VxFXLh
You can see that it is indeed g900f. I've also checked under the battery.
I've flashed the recovery you asked, however I could not find odin 3.12.7 only 3.12.10, so I've flashed with that (the odin thread on xda does not provide a link for 3.12.7 download).
You can see that it's still not booting with that recovery, it's just stuck at "booting recovery" screen.
I'm thinking perhaps it has a bad bootloader? How would you suggest to proceed?

Ok. Let's continue ... I hope (as I had very similar situation) that the phone is not hardbricked and eMMC memory is not corrupted -> I faced this on my phone and finally had to replace motherboard.
But let's be optimistic:
1. For data recovery - I don't have a silver bullet for this but I found this software: http://www.recover-android-iphone.com/recover-android/how-to-recover-data-bricked-samsung.html
It needs working odin mode so under condition that it supports s5 G900F it should be able to restore some data.
2. For unbricking - I recommend to flash via odin the latest official Samsung stock firmware dedicated to your friend's country/region:
https://www.sammobile.com/firmwares/galaxy-s5/SM-G900F/
You must be registered to download the software. Link for odin 3.12.7 is available on the bottom of the download page.
Just to underline - odin flash most probably (anybody please confirm that) will wipe your data so be aware of that.
Good luck.

Why a full firmware is needed? Perhaps I can flash only the parts required to get into recovery? I count mount the phone from recovery, that's why it's my priority.
I would like to know also if odin will wipe everything if flashing a full firmware?

Because it is commonly recommended way to unbrick a phone.

Perhaps, yes. But:
1. I don't exactly know what restricts your recovery to run properly. Flashing separate recovery failed.
2. You, for example, could try flashing separately one of the latest bootloaders dedicated to G900F from BL section with odin but I doubt it would help.

As far as I know yes but I am not 100% sure because I didn't try that myself on s5.
I would appreciate if somebody else confirms that.

In my opinion, if odin mode works then bootloader should be OK. But as you wish -
tell me first what stock firmware will you later on trying to flash on your friends phone or in which country the phone will be operated.

Latest available Firmware version for Hong Kong is G900FZHS1CQD1 however I can't find a separate flashable bootloader for you.
Generaly, in my opinion you might try any of the latest bootloaders compatible with SM-G900F phone (here you can find a collection: https://forum.xda-developers.com/showpost.php?p=54094068&postcount=3, I am on G900FXXS1CQI4) but again:
1. I doubt it will help for entering recovery;
2. I still recommend to flash complete stock firmware to unbrick the phone.
However if you anyway decide to try with a bootloader, flash it with odin from BL section (untick auto reboot). Also turn off the phone before and after flashing and pull out battery for about 30 sec. It happens that bootloader doesn't flash properly at once even the odin says "PASS" so some people reported that they needed to repeat flashing a few times. I managed to flash bootloader at first time.

Unfortunateely the phone is not with me anymore, so I won't be able to continue testing. Thank you anyway for trying to help me! I really appreciate your help!
