[Galaxy Note5 Q&A, Help & Troubleshooting] feras239:
Hello, I''''ve a Galaxy Note5 N920I which wasn''''t bought from Saudi Arabia. My phone doesn''''t connect to 4G at all and at best even if it connects to 3G the connection is pretty much slow, even the Dial-Up calls are not stable and _quotlaggy_quot. I''''ve noticed that whenever I change the data connection to 4G network the device gets considerably hot at the power button side. All of this happened suddenly without any prompt about 3 days ago... I''''ve already tried changing the SIM card and testing it on other mobiles and the SIM worked just fine, also tried to change the APN and network settings but nothing worked. I am really concerned about the idea that the device might explode at any moment.

I have the same problem, my device N920I which I didn't buy from Saudi Arabia but I live there. Samsung S.A didn't help me out but rather than that they told me to contact with Samsung's branch in the country I bought the device from.

At the current situation, I have no choice other than waiting the device to explode maybe.

I regret that I didn't choose Apple's iPhone actually, as they would help me out without such irresponsibility.

Anyway, I am waiting for your assistance.

Has anyone successfully downgraded SM-N920T Note 5 (T-mobile) from November security patch DPK6 to final 5.1.1. LL ****? Or everyone is getting binary errors?

I cant downgrade to lollipop from marshmalow. Everytime i am geting binary error, meanwhile my phone is galax A7 (2016) and security patch level is december 2016. Anyway, I am waiting for your assistance about this issue. Please help me.
[Galaxy Note5 Q&A, Help & Troubleshooting] Cool Person:
You actually do not need to downgrade to lolipop just install package disabler pro and disable all unnecessry service.
[Galaxy Note5 Q&A, Help & Troubleshooting] lumikin:
Package disabler doesn't seem to do anything for my battery life, and i'm using a rooted version of it.

are you on stock firmware?
[Galaxy Note5 Q&A, Help & Troubleshooting] betamax90:
i don't want to package disabler pro. my primary goal is downgrade to lollipop. Can i do it? help please.
[Galaxy Note5 Q&A, Help & Troubleshooting] :
No, you can't downgrade.
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
Don't give up yet guys. I am doing some scary low level stuff to try to get us downgraded and I will have one of two outcomes. A) I will replace the build.prop and/or anything else preventing downgrade.. or B) I will smoke this phone and I will buy a unlocked main board then ask my son to replace it for me. (laugh) I tried being a reasonable person but my ocd is kickin my butt so I'm on the impossible mission now.

(My working idea right now is to get build.prop patched to the pb2 version somehow. That should definitely brick me)

edit: I'm not convinced that I can replace enough stuff to force a downgrade as I believe it is tied up in the bootloader. I'm an average inteligence person and I think this problem will need to be solved by the geniuses of android, problem is they chose other phones. I do think we will have a solution if we hold off upgrading but it will probably be a little wait and even though I am still trying I doubt that my hack skills are going to penetrate the Android 6.01 bootloader.. (if you have ideas see my forced downgrade thread)
[Galaxy Note5 Q&A, Help & Troubleshooting] mika0056:
Does downgrading to stock 5.1.1 trip knox?
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
It's tied into the bootloader and something else inside of cache.img and they even have something in the system.img now on newer firmware updates.. When I tried to downgrade using a box I bought it would start to flash and show me the % percentage amount flashed but would then freeze and say "wrong reply" and I'm assuming that has something to do with receiving the wrong password or something.

---------- Post added at 07:52 PM ---------- Previous post was at 07:51 PM ----------

No but you won't be able to downgrade once you've taken a certain firmware update. It'll prevent you from doing it.
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
Mike I got farm-root working for Note 5 which pushes and pulls recovery/boot image to the /dev/block partition. Or at least it seems to work I haven't tested it with anything except my legit images because I'm not willing to, I'm just the hobbyist hacker. One thing I realized is if I can push /boot and /recovery with the ol dirtycow then I can likely hit the bootloader directly with an unlocked one pulled from a like device.. Then wouldn't you be able to follow that with twrp?

if you need me to change the toolbox.c to point at your /dev/block/ let me know. Mine is this:

/dev/block/platform/15570000.ufs/by-name/RECOVERY"

so adb shell, cd /dev/block/platform/15570000.ufs/by-name, ls -la you should some sym links BOOT, RECOVERY pointing to partions SDA or whatever

(full path needed like I listed above and I can compile it for you no problem)
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
Mine are the same as yours.. Earlier today I tested COMBINATION_FA51_N920VVRU2APA1_CL7082958_QB8376876_REV00_user_mid_noship just to see if it would work and it DID but when the phone went to reboot the notification light lit up white and nothing came on the screen!! It would not boot or anything! No recovery nothing! I even selected factory reset and it wouldn't do it either! It's working again after reflashing BPI3 with odin.. I'll try whatever you want me to lol.

By the way, I think if you tried to flash anything other than the legit images then farm root won't work.. it just seems like it's working because you're using images that we're allowed to use.
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
I decided it's just a 200 dollar phone and I'm having fun so I started testing.. :) You are correct it isn't going to boot as it is but I am writing to and I can write to any part of the phone now. So we are going to get around this problem. For months I have been unsure if I would ever be able to be confident about that but now I am. We will take down our bootloader with dirtycow, we won't be the first.

But yeah I can flash modified images then I get a blue screen with white writing basically phone modified, take to at&t for repair. But I just flash back boot.img or recovery.img then it is fine again. This absolutely is writing 100% for sure. I have verified with code by pulling it back but I have a way anyone can verify. flash a recovery but don't enter recovery mode let it boot. boot as many times as you want. Then enter recovery mode, no more booting for you until you flash recovery.img!! chain of trust doesn't know recovery.img has been changed until you access it then after that it knows, rebooting won't solve it.

But back to the point if we replace the bootloader to a copy of an unlocked bootloader chain of trust turns off and the phone boots. See what I'm saying? And if I can over write boot.img and recovery.img with an unsigned image I am outside of the check, the bootloader isn't being asked anything because normally that would be rejected but now it isn't. I am confident that I can downgrade Note 5 phones by writing the sboot.bin from the original release along with the system.img at the same time. But I am not 100% sure, not enough to release that code for someone to try until I think about it more (test it on something)
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
So where's the farm root for me to test out? All I need is to push su to the system folder which we cannot seem to mount as RW.. does anyone actually have a sboot.bin that's not locked down? There's a lot more partitions that are not being shown too you know that right?!
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
farm root for Note 5 is on my github with instructions. I have a feeling sboot.bin contains device specific information after installed but I will try to confirm that. If so that means we can't just take an unlocked bootloader from any device. I know there is a hidden partition(s) but I'm not sure what it is I haven't really started sorting through this officially yet. But I don't think they are hidden from root + system_server or root + install_recovery .. Hopefully I will be back working on this in a few hours. I wasn't planning on exploring hidden stuff as a default go to (should i?)

I could easily pull some info with elevated privs, just what info should I pull and how? (like you think it out and i code it if you're willing)

Edit: Sorry I meant to mention my whole fall back plan right now is simple writting sboot.bin + system.img from the original lolipop 5.01 release. Not unlocked, just a very forceful downgrade. The important thing is I can't mess up and not write something all in one go.. (like downgrade the bootloader but not the system, fail, will have to flash firmware back to mm)

(am I missing anything? maybe from the CSC partition?) boot, recovery, userdata can all be written any version no check already. modem also
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
I already did a forced downgrade on my nix box I was able to flash all the images and .bins that needed to be flashed but after it rebooted it simply gave me a black screen with the notification light lit up white and the only thing I could do was hold down the power and volume down buttons to get back into download mode because even if I selected recovery or tried the recovery button combination it would just give me the black screen and white notification light and that's it! It wouldn't even do a factory reset however I noticed that there is no cache.img in the combination folder and from what I know it needs to be flashed in order to make the phone think it's upgrading or updating and I tried flashing several different ones from several different firmwares and it just refused to flash.. That's where I'm stuck at but I can always reflash the last firmware that I was using and everything is fine again..
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
One thing I am thinking with your problem right away is that cache.img happens to be an image I remember seeing included with twrp for Note 5. If that's true, and it could be wrong, then it might be fun to take that cache.img and include that into your combination file. The only other thing I can think is to just make farm-root consecutively replace each image on your list but include anything missing that you want also. (power combo file).. but I don't know what a nix box is it didn't google easily (assuming it's a powerful little box you can order up to flash stuff)
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
Lol no a nix box is a Linux system.. I can't stand windows so I don't use it! But I did buy a box to flash with similar to the z3x.
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
Ok I see. Yeah in that case you can just build out the list of what to flash with heimdall-frontend and test whatever cache you want.
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
Tried with heimdall too and the cache reached 67% and then stopped and won't finish..
[Galaxy Note5 Q&A, Help & Troubleshooting] fdogic:
omg i am looking forward to android Oreo and these guys want to go back to lollipop. hmm
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
Oh yeah I think cache.img is one we have to replace also. I am working on something I think will solve your issues or at least be a lot of fun. farm-root that pulls and replaces all of the visible partitions.

So I tested some pulls on different partitions now including what I think is the bootloader, the very first partition. I know we have the horsepower we need but for our tool to work for now two things must be true. 1) the images we write must be signed images but that includes any official firmware version available to you. 2) Our write needs to be consecutive and include every file needed, for example sboot.bin, system.img, cache.img and then the rest too just for good measure.. I am using dd to write and I know it is writing correctly so when I forcefully write all the images for Android 5.01 which does infact match the hardware signature I know it will boot up Android 5.01.. (but also I think we don't have to write bootloader!!)

I personally am running boot.img from the previous baseband S3 binary when I am on S4.., love it, runs great.. that's why I don't want to root because I lose < 1% battery overnight, it's Android 6.01 and Samsung can't upgrade me. I screw with props after boot, I change others stuff. (oh and also I have a PE6 versoin recovery.img which works also, I can clear cache and wipe system..)

That's how I run my phone all of the time.. It is is so mixed backwards it can't be updated by trickery now, crash crash crash goes their attempts.. but it runs without error messages except att software updater when i first turn it on.

So maybe now you understand why my confidence is skyrocketing. I think actually we could leave the bootloader as is, downgrade everything else and it will run fine.. It's not the bootloaders job to check version post flash.
[Galaxy Note5 Q&A, Help & Troubleshooting] frknl:
did you guys try to flashing pre-Octaber MM ROM to Note 5?
[Galaxy Note5 Q&A, Help & Troubleshooting] Rainbow_Dash:
I actually did successfully downgrade to lolipop today from nougat.

It was hard as **** and required a cluster of bootloader mods (including flashing samsung engineering files)

I will write a guide tomorrow perhaps

And yes before anyone will ask.....it will apply to the note 5
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
You have an unlocked bootloader so it's easier to downgrade like that! People with locked bootloaders aren't going to be able to do this unless you have the eng files to flash and even then it may not work.

---------- Post added at 06:58 PM ---------- Previous post was at 06:56 PM ----------

That's exactly what us developers expect someone who doesn't understand to say!
[Galaxy Note5 Q&A, Help & Troubleshooting] Rainbow_Dash:
(Im actually talking about combination files and bootloaders yea)

And i have flashable unlocked bootloaders (by unlocked i mean downgrade-happy) for all note 5 variants (except the n920r4). Could upload em. Not an issue.

And i asked a few testers to try it out and it worked for the n920c and g928f and g928c variants (dont have any testers for anything else lol)

Tbh theres quite a difference between nougat and lolipop.

From the 5hrs ive used lp i can say its faster. Even tho tbh even nougat was fine as-is.

But battery life is terrible

---------- Post added at 01:27 AM ---------- Previous post was at 01:04 AM ----------

Its not really about the version itself or what it has to offer.

Its more about the sense of....control that you have over your phone. Samsung to put a bootloader that doesnt let you downgrade is......wrong at the very fundamentals of android.

The only other company who does this is apple and......well.....lets not get into that
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
I have the Verizon and AT&T variants of the Note 5 both with locked bootloaders but I'm always willing to break them lol.. So if you have something I can try I'll do it and let you know if it worked.. I did try 1 combination file for the Verizon variant and it flashed problem was when I rebooted it, it turned the notification light on a white light and black screen, nothing else.
[Galaxy Note5 Q&A, Help & Troubleshooting] Rainbow_Dash:
Let me see........

The only combination file i have for the N920V is this:

http://d-h.st/TDsU

Just let me know if booted. The downgrade procedure itself is kinda different and complicated
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
Same one I tried already. Flashed via heimdall and passed but tried flashing that with odin and failed. The flash with heimdall-frontend gave me the white notification light and black screen.
[Galaxy Note5 Q&A, Help & Troubleshooting] Rainbow_Dash:
At what file exactly?

All we need is the sboot and boot.img to flash rest is useless.

Try to delete all other files except those,create a tar and flash

In odin (i never made heimdall work w my phone so donno what to say)
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
It failed instantly on cm.bin on odin but that really isn't an issue I can get around that easily.. Because the bootloader is locked when I try to flash an older version of say system.img or cache.img it will not go! And I noticed the only way to get the phone to boot after changing everything is to flash a cache.img that will work and then the phone will boot back into it's old system aka the last working one. Oh and heimdall-frontend doesn't go on the phone it's for use on Linux and other similar Unix systems like odin is for Windows.
[Galaxy Note5 Q&A, Help & Troubleshooting] Rainbow_Dash:
Yea i had that issue when i first started testing too.....

System rev check fail

I got around that by flashing an 5.1.1 rom in twrp and then after that (bcuz it wasnt booting) flash the bootloader in odin.

But i guess thats not a solution for you since you dont have a twrp for the n920v
[Galaxy Note5 Q&A, Help & Troubleshooting] MrMike2182:
Correct because the bootloader is locked and checks every file before allowing it to flash.

There is now a tool available that allows dirtycow vulnerable devices to pull any partition you can read from your device all at once.. (or all of them..) you can also write them back!! I have done limited testing but I've tested it a lot..

If it doesn't load by the way just add a screen lock password, then remove it.. sometimes I have to do that a couple times but it always, always works.

back soon, let me know what you can do with it!!! pulling BOTA0, BOTA1 is safe I've done it 20+ times.. writing it back, hmmm... that's the bootloader bruh be, like, all, nervous and stuff
[Galaxy Note5 Q&A, Help & Troubleshooting] lumikin:
Very tired right now, so all this just looks confusing. If you have the time, can you look into writing up something for the newbies please? Particularly when it comes to simply downgrading the BL as that's mostly where people get hung up when installing a 5.1.1 ROM.
[Galaxy Note5 Q&A, Help & Troubleshooting] droidvoider:
My research right now is 100% focused on downgrading to 5.11 with interest to gain permanent root for people then taking it back up to nougat, that's my whole gig now. This will be to solve issues with switching carriers and to repair phones which are trapped between combination file setups. When it is working 100% and tested I will port it to Windows, it will have a ton of error checking included and etc. To do this I need to research very carefully all the information and then fire my test on a less expensive device. Only then will I say this thing works.

I will have time to work on this again soon. This is fun stuff for me I love researching, building.. I am definitely open for help with research on replacing BOTA0, BOTA1, SYSTEM <and anything else blocked> with the original 5.11 firmware. The first move for helping me with that research is to pull the image, compare that image to your version firmware to discovery exactly what each file represents.. sboot.bin, cm.bin, param.bin, recovery.img and etc.

The other idea is twrp to help with that we need to know for a fact the addresses match 100%. We need to take down BOTA0, BOTA1 with whatever is on the Note5 unlocked with twrp.. I need the finalized partition file to flash them individually, absent any mac addresses, serial numbers for device and etc.. To know if that's a problem we could simply review the twrp sources to see what's what.

I know my information on this tool is poor right now. Please carefully review everything before writing. I have destroyed BOOT and RECOVERY completely, I have written twrp to both.. while it gives the at&t error I get to download mode with pwr + vol. down.. it's reluctant, but eventually black screen then I grab power + vol. down + home to hit download mode.. But please realize I haven't wrote to BOTA0 or BOTA1 even as a test with my own image yet. that needs some thought first and is why I didn't include it in my example. I would love to hear some successes but it will literally make me sad to hear you bricked it. don't brick it i will work through this slowly and safely in a matter of time..

if you need to stop the carrier apps do a search for my thread on this for disabling carrier apps on Note 5AT&T they will crash then stop for the most part.. 90% of the apps I crash out give a message at startup then never again.

Lollipop battery drain

Hi Guys,

I just downgraded my Galaxy Note 4 910C from Marshallow to Lollipop 5.1.1. using this forum. Big thank you to everybody. Process was very easy.

Immediatelly after firmware was installed, I noticed that the battery estimate time was 9 hours?????? Battery percentage was about 90%, phone was fully charged to 100% before downgrading.

Battery on MM was performing fine, with solid usage/idle some 26 hours was estimate time, with heavy usage some 9-10 hours.....thats what I remember. :confused:

Also, immediatelly after switching WIFI on, received a notification that I am able to update to MM over OTA :laugh: so if you are worried that you won't receive updates, don't be.

I always Google when want to do something, but this problem can't fix.

My question is what to do to have battery life like before, like on MM? Also recently purchased brand new OEM battery and drain is the same. Phone is 16 months ols and came with MM.

Thank you in advance.
