[Galaxy Note 4 Q&A, Help & Troubleshooting] Kawalpreet Juneja:
Hello,

1). Rebooting while restoring isn't normal. Were you restoring system app? I can't say much on this since I never experienced reboot while restoring. For system apps, I install apk manually, or if it's already included in ROM, I choose 'data only' as restore method.

2). My CPU's temperature usually crosses 70°C on multitasking (not that much on gaming). This is problem with Snapdragon processor. About normal behaviour and max. temperature, I can't predict anything. It can go to any level. By the way, my device is much cooler after flashing Ram Kernel. You won't find link now since it's removed:( But you can subscribe to that thread for future updates.

3). USB debugging have nothing to do with Titanium Backup. Why would it be?

And it won't affect anything unless you connect your device to computer with USB debugging on and do some serious ADB commanding.

4). Yes. Greenify. I have also selected many system app with it. What it does is that it force closes app and not let it open again until it's done by user. You can check screenshot to see settings.

5). SD maid is a good tool for cleaning. It doesn't matter which app you use for freezing app since all perform in the same way. But I recommend you to visit link that I've attached. It contains list of all unnecessary apps that can be removed (uninstalled). It also contain list of app that are safe to freeze. This will help you to free up CPU and RAM usage.

Hello , hope this post find you find

1- i never backup system app , restarting happened in 2 apps only , your point is clear regarding restoring data only for system app

2- My CPU temp sometimes reach 72 , at normal condition it below 37 for cpu & below 30 for battery

3- when i run titanum backup it give me a notification regarding system configration and ask me to enable debug mode from developer option , so i asked you

4- i use Greenify too , and modify the seeting according to your screenshot (don't have xposed frame work yet , will ask u later about it :) )

5- i will not uninstall any bloatware apps , only freezing it , i review the list for safe freeze , i select from it , but i wounder as it miss instagram app , is it safe to freeze ?

here is the list off apps i freeze , bluetooth (com.sec.knox.bluetooth) , dropbox , email , evernote , facebook , galaxy apps & widget google play books , games , newsstand movie , music , google + hangout, instgram , all KNOS apps , page manager , peel remote , pen.up , samsung content agent , samsung push service , samsung dlp service , security log agent , waether , launcher (com.sec.android.emergencylauncher )

note : for bluetooth (com.sec.knox.bluetooth) + launcher (com.sec.android.emergencylauncher ) i don't freeze them i find them freezed , don't know why

appreciate to review the above freezed app & tell me your opinion

Here is my today update :

from last post i wrote to you , my device work well , no significant battery consumption all the night when it lock , it restart when

1- freezing above list ( actually after i restart by myself to check functionality , it restart twice )

2- when i install facebook messenger

3- i add the following to freeze list , facebook app installler , facebook app manager

New update

device shutdown & can't power it on as happened before

last thing i did on device is : installing root booster & some automation apps like tasker & macrodroid

I have a question regarding s-finder in note 4 running stock kitkat. My note 4's s-finder and my files app can search for keywords inside a pdf, document, powerpoint files without opening it and shows results like a mac's spotlight and windows search. Unlike the note 4, both my note 5, s6 edge plus, s7 edge running Nougat and marshmallow previously is unable to show the same results. It would only display results related to the title only. The note 4 can search for keywords inside a big pdf file (>1000 pages), word document or any file. Any idea how to fix the newer devices.

SD card size brand?

Hi,

I tried to search for this, but I think I am not using the correct terminalogy....

I have a note 4 ( N910T ) Which I have rooted, put TWERP on, and am looking at various ROMs to play with.

My Question: What is the max size SD card I can use?

I ask becasue I think the official limit is 64 .. but in my wandering all over the net, I saw several people say that they are using even larger then that.. like 128 and 200 gig...

The larger size cards are significantly more expensive... so I would prefer to get one that I know will work, so I woudl LOVE it if you have the same phone, and use a larger sd card, if you could tell me the brand and modle as well...

Thank you in advance!!

Danny

P.S. Considering my first computer was an Atari 400 with a CASSETTE Tape drive for storage, I am blown away with what PHONES can do now!!! (Then I bought a floppy drive for it.. for only $350 )

I just swapped out my wife's Note 4 (old one died). I got the new one activated but no 4g. Ad I get a message: Unable to establish a wireless data connection EHRPD: 7

OK it's been years since I last visited XDA, so I can be considered a "renewbiefied".

A friend game me a 910F with a problem and I try to figure out what to do.

The device boots to Android and a few seconds (or minutes) later, it resets and goes to download mode.

I suspect something is wrong with the ROM image (except if there is something else you happen to know).

So I would like a newbie friendly point to the direction of how to reflash stock ROM (and which and the tools needed... the works).

Please?

Next step install Twrp - https://xdaforums.com/note-4/orig-development/tool-utility-twrp-2-8-1-x-teamwin-t2956011

From now you have two options :

Hello, i own an 910f, few days ago i've flash cf autoroot / twrp / Dr Ketan's M12 Rom everything juust perfect, best phone / Android I've ever had..

Yesterday i wanted to have my snapchat back and being noob i didn't know that snapchat "knows" when the phone is rooted.. I've searched Google and saw that only solution was installing Magisk.. I've unistalled SuperSu, installed Magisk and i think by mistake i pressed the root option too, the phone was rooted with Magisk.. Untill. Now everything was good.. Snapchat trick works.. But i wanted to have back Super Su.. Unistalled magisk from the program, unistalled from Playstore and flashed UNINSTALL ZIP for Magisk provided by Magisk Developer.. I start flashing super su back but.. S**t! It doesn't want to install / root my phone anymore..

I tried with Odin also with Twrp (both ways).. Super Su doesn't apper in apps and when i'm installing it from the Play Store it tells me that the phone is not rooted..

My question is.. What i'm doing wrong? What can be done to have my classic SuperSu back..?

Sorry for my bad English, have a nice day gentlemans

EDIT : I wiped everything and reinstall Rom back, rooted the phone with SuperSu and everything is back to normal.. As an advice i found out that Magisk and Dr Ketan's Rom don't work to well together at some points

Note 4 how to revert to stock?

Hi

I'm not a youngster and struggling a bit I was wondering if you are able to help or point me in the right direction.

After rooting my note 4 I am unable to run my banking app, I get the message unable to run on rooted devices. I use this app more than most to ensure I don't overdraw etc.

Question is can I revert back to how things were before the root. Not sure what details need but here are some:

I used Odin and twrp-3.0.2-0-trltexx.img.tar, UPDATE-SuperSU-v2.76-20160630161323.zip

Hi all, new to the forum but long time lurker.

My name is Lee and I have a Note 4 SM-N910F running Android 6.0.1. On the Vodafone network in the UK.

I've been tempted to install a custom ROM on many of my android phones but never taken the plunge.

My contract just ran out, and now I'm sim only, thought I'd finally give it all a go and liked the look of Dr. Ketan's N7 rom.

So, utter noob question, but what should I do from start to finish?

My understanding is:

Back up stuff on PC first.

cf-auto root/super su.

Twrp

Backup to sd

Put rom on sd

Boot to recovery

Install rom.

Am I missing anything or is that pretty much it? If anyone has a few mins spare just to make sure I'm not going to screw anything up and point me in the right direction (hopefully not the door!) it would be most appreciated.

Thanks guys!
[Galaxy Note 4 Q&A, Help & Troubleshooting] callumbr1:
That's pretty much it buddy in that order.

Before flashing custom rom, in TWRP, Wipe data/cache then flash Rom.

---------- Post added at 04:14 PM ---------- Previous post was at 04:14 PM ----------

Reflash Stock rom.

Or use full unroot from SuperSU app.

[Galaxy Note 4 Q&A, Help & Troubleshooting] madlee7:
Funny you should say that! I've put the BL and Modem md5 on the sdcard along with the ketan rom zip.

Do I need to do anything with the BL and Modem thing? Only the ketan zip shows up in twrp.

The instructions in the ketan thread only cover flashing with odin and it says to copy the md5 over with auto reboot unchecked etc before installing the the ROM.

Just checking as I don't to screw up! (Everything is backed up though).

also, just noticed you're in Leeds. I'm right next door in Sheffield :)
[Galaxy Note 4 Q&A, Help & Troubleshooting] callumbr1:
Before you do anything else, in TWRP go to backup, backup your efs files. This contains your imei and if that gets corrupted you will not have Mobile signal.

Then you don't need to do anything with BL and modem. Just go to install in TWRP, select the rom and swipe to flash.

Wow that's close :) not far at all.

EDIT: You may need to flash the bl and modem through Odin depending on which you have now. But you can flash the rom and then if needed flash them.
[Galaxy Note 4 Q&A, Help & Troubleshooting] madlee7:
Cool. Thanks ;)

It's finishing the first boot now fingers crossed!

I chose to back up EVERYTHING with TWRP btw, so I'm good there.

[Galaxy Note 4 Q&A, Help & Troubleshooting] madlee7:
Well I flashed the modem with the recommended file and then it got stuck in a boot loop.

Tried to recover things but it still got stuck in a loop.

Rewiped, then followed instructions exactly by installing modem first, then the rom. Still bootlooped.

Ended up with it softbricked.

Managed to get a BOC5 Rom and flashed that for now. :eek:

Flash TWRP first, then flash SuperSU through TWRP. Then flash Rom.

Or flash Rom without root as it's pre rooted so it will Root your phone during flashing process.

It won't let me boot into twrp at all. If i use twrp in android, it won't let me download twrp file. Says there is no sdcard to download to. I fi reboot to recovery from within twrp, it takes me to stock recovery and says dm-verity verification failed.

Edit: Also, tried to put the twrp img on from windows. Windows recognises phone. Shows storage remaining on card and phone but when I go into either of them, it says they are empty despite several things being on there.

Edit2: factory reset and cache wipe seems to have sorted the problem.

Twrp on.

BL and Modem on.

Installing Ketan.

Fingers crossed.

Again.

Installed ketan, wiped cache/dalvik.

Applied fix.

Wiped cache in twrp. Still the same. Sigh.
