Boot Loop due to Software or Hardware Failure?

Hey everyone, I'm having a problem with my Samsung Galaxy Note 4. I came here hoping someone could give some closure on what is wrong with my phone as I feel I've done as much as I can in fixing it, anyway.

Model Data

Samsung Galaxy Note 4 (White) 32GB

Model: SM-N910G

SSN-N910GGSMH

Running Android 6.0.1

What happened: What started the first crash and the sequence boot loop is confusing for me but it's what happened. I was about to download data for an app whilst it was open but I didn't want to use my mobile data so I switched to Wi-Fi at the last second before the download started and then the phone crashed. From here it goes into a Boot Loop.

My solution: After searching the internet I used ODIN to perform a Flash since I have NO recovery mode access. Using the N910GDTU1DQL2_N910GXSA1DQL2_XSA.md5 file from the SAM Mobile site. The furthest I got using this method was making it to my home to turn off my Wi-Fi and Mobile Data before the phone crashed again, restarting the boot loop. I tried this method many times. As I have no real other idea what to use I also tried using a .PIT file for N910F 32GB since there was some forums saying there was no difference in how it's applied on either N910F or N910G phone. No success to that either, ODIN didn't even let me flash the phone that way, failed every time. I have no developer or de-bugging tools installed on my phone only Play Store Apps. Outcome from my trying is looking pretty bad.

Outcome/Ideas: I'm still stuck on a boot loop with the rare opportunity for my phone to make it past the 'Installing Upgrade' stage. But If I make it back to my home screen again I would try uninstall the app of which I was on when it crashed the first time. If not can somebody please tell me, exactly how do make my phone to a perform a factory reset state without access to recovery mode or phone apps/settings. Or using only ODIN.

I'm completely stumped on what to do next. I don't know if this is a software problem or a hardware problem at this stage. But I'm open to any ideas and help if provided. Thank You.

Is there a way to network unlock my AT&T phone myself??
[Galaxy Note 4 Q&A, Help & Troubleshooting] NShort:
Hello

I have a friend whose son died in a bad accident, 27 yrs old. She wants to unlock his phone to recover any memories of him. The model is a Samsung Galaxy 4 Note with Sprint carrier, US.

The phone is locked of course and is stock, un-rooted. I need to flash TWRP so I can use the recovery menu to load a script to disable the lockscreen. However, I am having trouble figuring out which version of TWRP to flash via Odin. Since I cannot get to the actual model number my best guess is either dl.twrp.me/treltexx or

twrp.me/samsung/samsunggalaxynote4qualcomm.html

Any help with this would be fantastic. Thank you.

Note 4 won't boot.

Hi everyone my note 4 fell but there were no physical damages or cracks to screen or the phone. The phone worked good for about 2 days after the fall but while I was using it the screen just kinda blurred like the attached pic and the phone never came back on it would just show the first boot screen when i try to turn it on, I have already tried to flash stock rom from Odin but still nothing cant boot to recovery only download mode . Could it be that I just need to change the screen or could it be some other hardware failure? Attached is a pic of the android man loading after flashing stock firmware.

New to all of this

I just inherited (Literally) a Note 4 from my father in law after he passed. I believe it is a Sprint variant of phone. I have looked around and seen there are Snapdragon ROMS and another type calle EXYNOS. How do I know which I have? Also, after clicking on each individual ROM post, there does not seem to be an in depth guide on how to actually do it to your phone. Is there somewhere else I should be looking for that information? Thank you for all these resources.
[Galaxy Note 4 Q&A, Help & Troubleshooting] w41ru5:
Install the app called CPU Z or Phone Info for Samsung.

There you will see what type of processor it has.

Usually Sprint and the American market has Snapdragon type.

If in doubt, post a screenshot here.

hi,

i currently have J7 Prime (2,5 years old).

is it worth it to change to note 4 from J7 Prime.

note 4 prices are reasonable here

2nd hand j7 is 100$, 2nd hand note 4 is around 170$

is it worth it?

I have asked on the corresponding thread (https://xdaforums.com/showpost.php?p=83170981&postcount=873), but concededly, many if not all, no longer use Alliance ROM v2.2 (Android Lollipop 5.0.1 custom TouchWiz).

I would like to know if anyone has experience using Magisk on the said ROM? I am aware Xposed is not supported.

[Galaxy Note 4 Q&A, Help & Troubleshooting] bitbang3r:
I've been out of the loop for a few years, but I'm trying to get back into AOSP development using my old Note 4 (mostly, because it's one of the few devices I have that's both AOSP-capable and I don't actually have to depend upon for anything). It's been in a drawer for most of the past few years, so I'm trying to quickly get back up to speed with it. I know a lot has changed since the last time I really played with it.

It's a T-mobile SM-N910T that was officially unlocked by them a few years ago.

The baseband version is N910TUVU1COG2

The big things I need to know to get started again:

1. What's the device tree name I need to look for when building/flashing AOSP/Lineage/TWRP/etc? trlte? tblte? Something else? Was development for all the Snapdragon variants eventually consolidated, or are the unified ROMs still less stable and shakier than the Tmo-specific ones?

2. If I have an unlocked Tmo version, but I'd REALLY be using it with an AT&T SIM on AT&T, do I still want to go with the device tree name from #1 (assuming it's Tmo-specific, and not unified)? Or can/should I pretend it's the AT&T version going forward?

3. What do I need to do to get the best-possible radio modem firmware installed for using it on AT&T? I'm a little fuzzy about how this is supposed to work now. I know that in the past, a T-mobile phone (even unlocked) was a T-mobile phone "forever" insofar as the radio modem went... but I also know that sometime around 2015, Google changed the way Android phones are supposed to deal with this, so an unlocked phone with available radio modem firmware for multiple networks is NOW supposed to pick the best-available firmware when it wakes up connected to a new network. What I'm not sure is whether this semi-retroactively applies to phones like the Note 4, or whether that policy applied only to Nexi/Pixels, or whether the Note 4 is too old for it to apply.

4. Are there any baseband updates I should bend over backwards to avoid, because flashing them will slam the door on being able to do other desirable things like unlock the bootloader, disable Knox, etc?
[Galaxy Note 4 Q&A, Help & Troubleshooting] bmwdroid:
@bitbang3r can't answer but recommend to ask in the telegram group lead by ripee and triplr.

If you search there for triplr you'll find it.
[Galaxy Note 4 Q&A, Help & Troubleshooting] bitbang3r:
Well, I eventually figured out that:

trlte is apparently the general tree for Snapdragon-based carrier-branded SM-N910 phones (including the SM-N910T)

trltetml is specific to the T-Mobile SM-N910T... but as far as I can tell, is now mostly moot for AOSP, because everything AOSP-based targets trlte

trltexx is the SM-N910F... nominally, the same hardware as the carrier-branded Snapdragon-based models, but sold by Samsung as unlocked and non-carrier-branded.

I'm still trying to find an AOSP-based ROM to try building. I've done it in the past... but really, not since ~2013 (Galaxy SIII). Ideally, I'm looking for...

Official support by the ROM's devs for the n910 (ie, not one that's alleged to work as an experimental build in a 490-page thread that can ultimately be summarized as, "oops, I guess it didn't really work all that well on a n910 after all...")

Build files that the creator actually tested at some point with a fresh Ubuntu install. Google and Lineage tend to be pretty good about doing this... most of the others I've encountered over the years... not so much. It makes me weep for the "Golden Era" S3 days when devs would release VMs of their entire build environment (dependencies and all) alongside it for others to use directly, instead of having to spend days wading through dependency hell.

I wouldn't actually try to flash that scratch-built ROM first (I'm not that crazy), but given that re-learning how to do it is my main goal, I want to make sure I can at least get the ROM's build process to successfully run to completion before I invest hours installing and configuring it. I've encountered way too many AOSP projects that are just flat-out broken (mostly, due to all the radical changes Google made circa 2016 that catastrophically broke just about everything written before them, and killed just about any Android-related project that wasn't being actively maintained & reworked every 6 months to survive Google's next round of radical changes).

[Galaxy Note 4 Q&A, Help & Troubleshooting] SamaelThuum:
Hi, a have a ton of questions but I think they're all noob so maybe someone can help me with all of them please? I used the search this forum but didn't find my answers

Please consider this for my questions:

+ N910C with Exynos

+ I live in Colombia

+ I use banking apps that can detect root and would not open at all, (I bought an S10e but it was rooted with magisk and apps detected root, even after enabling "hidemagisk" options, I'm selling it right away bc i need these money apps working, and overall don't want any app to not run because of ROOT. The only reason I'd be interested in root would be to debloat and MAYBE some customization to stock TouchWiz/stock rom that'd require root

+ I DO use and need the pen and all features around it

Questions :

1. Is there any ROM with android 8 or newer I could have without Root? Or at least that my banking apps would act normally and wouldn't detect? Is there with Android 10?

EDIT: Answered by @bmwdroid (ty!)

2. Can I stay on stock 6.0.1, root to remove some bloat, UNROOT and would my banking apps work again?

3. In case it was viable for me to root stock 601, what are some "modern" tweaks I could do, without and with Root. I'd be interested in dark modes in as many places possible, like settings, also, i like stock launcher touchWiz but would like items size smaller to fit more things/icons/grids in screen, like in modern S8 or newer, where there is even a slider in settings for that

4. The battery on the unit I bought totally sucks, won't pass 87% and dies around 50%, what batt would u recommend me look for? I know that 99.9 of "genuine" batts out there are just useless counterfeits like the one I have right now (doesn't even have NFC antenna) and that all those in ebay/aliexpress claiming capacities of 4000-6000mAh are complete BS.

The only batt I've ever seen for this phone (haven't tried it) with proof of good quality (people uploading pics and testimonies of using mAh counter devices) is of a brand NOHON (Chinese I think) but everywhere I find it it's only 10-20usd but shipping is like 30+usd, which is in total what I paid for entire phone $45usd

EDIT: QUESTION 4 answered by myself,

Ok, I figured since batt is available at AliExpress but very expensive shipping to Colombia but free shipping to USA, I guess I'll just ask a friend who's coming on January from USA to bring me a couple of those NOHON batteries

Ty for answers. I know many ppl trying to use this phone nowadays would find all this very useful

Afaik there is NO custom ROM which will support s-pen fully.

Only marking, drawing and pointing possible.

The rest is blocked by Samsung to be implemented in not Samsung ROMs.

I have three (sorry 4) different Samsung devices with custom ROMs and S-pens but none has full features.
[Galaxy Note 4 Q&A, Help & Troubleshooting] bmwdroid:
@SamaelThuum perhaps best to look for a debloated stock ROM.

You can use then TWRP and stock as well.

Used to have that on one of mine.

Without Magisk you'll have no root so that should suit your banking apps and you keep spen functionallity.

There are many custom ROMs out there 4 the note 4, what is the most stable AOSP-based custom ROM 4 the T-Mobile variant?
[Galaxy Note 4 Q&A, Help & Troubleshooting] SGN4User:
Dear XDA Forum Senior Members, Members and Co-Noobs (yes, I fall in the latter category)!

I have been a user of a Samsung Galaxy Note 4 (N910C) for the past 6 years, and I still feel this is the best device ever built. I would like it if Samsung continued to build devices that have removable battery, Infra-red blaster (aka universal remote), heart rate monitor, plus all the other great features this phone has. Sadly this is not the case, but life is what it is. Anyway, enough reminiscing.

First off, I really appreciate the fact that there's a NOOB FRiENDLY post, which is exactly what I need.

My question relates to security and software updates for the Samsung Galaxy Note 4. I know that Samsung devices usually get security updates for normally 2 years, then they are no longer supported in terms of software updates for their devices. Hence, I was surprised when I recently received a notification stating that there is a software update available for my device.

The new version (according to the notice) is N910CXXU2DVG1/ N910COJV2DVG1/ N910CXXU2DVG1 and file size is 389.90 MB

The current (existing) firmware version is N910CXXU2DRL1/ N910COJV2DRL1/ N910CXXU2DRL1

Other information: Product code is SM-910CZKEXSG; Firmware CSC code is XSG; CSC country is UAE/ AE. Note that the device is using stock ROM (v.6.0.1) and is not rooted.

Before I allow the software to be updated in my device, can anyone confirm that the information above is the latest firmware version? I could not find information regarding this update anywhere.

If indeed this is an official update, then I am impressed that Samsung is still supporting this device.

Regards,

A Samsung Galaxy Note 4 fan

[Galaxy Note 4 Q&A, Help & Troubleshooting] ananjaser1211:
Very late reply, but i recently was working on one of my custom note 4 ROMs and noticed a familiar bug report in GPS, sometime in 2021/2022 majority of samsung phones got an update out of the blue (even ones older than 5 years) to do "gps improvement" or whatever, it turns out it was due to a GPS 10-BIT Rollover bug that basiaclly screws up GPS time.

the main purpose of this update was to fix that GPS time bug (which basically makes the phone think GPS time is 2003 instead of what it should be)

more context here (S7 / S8) and here (Note4) , this bug as far as i am aware spans devices from the note 4 all the way to the galaxy S9, as i had to manually patch the issue in all my custom ROMs, in the second github issue page i attached screen shots of GPS before and after the patch

[Boring context about the rest of the update]

You can get details on what each update does via the official samsung notice page https://doc.samsungmobile.com/sm-n910c/xsg/doc.html , this is what the OTA/Updater app pulls for changelog / description

Anyhow, i thought the note 4 was exempt from that as i did not see any newer firmwares at the time, but it turns out there was, in august last year DVG1 was pushed to all models, however the N910C and N910H only (dunno why) did not actually receive a full downloadable firmware, i.e one you might get from sam mobile, samfirm etc, instead they only got an OTA update

there have been some other minor changes in the firmware, but i dont think there is any "major" or worthwhile change aside from the GPS Bug, also the baseband firmware was updated (to N910CXXU2DVG1) the bootloader has not been updated since latest release (N910CXXS2DRL1), other parts of the firmware had timestamp changes for the most part, the android framework did change but i did not bother to inspect it beyond just comparing file changes

somewhat of an important change was that the device google fingerprint was updated, which might deprecate the older N910CXXS2DRL1 or N910CXXU2DSA2 fingerprint, which means it could start failing safety net checks.

You probably flashed a wrong file. You could try to fix it by selecting the correct checkbox in Odin and then flashing the correct files.

Also, why don't you use LineagrOS 18? There is a very long way since Android 5.1 and there is zero reason to stay on stock ROM since LineageOS 18 have almost every features of the stock ROM.
