Are you at least seeing a splash screen and continual reboots?

You need to format data and factory reset and try to reboot. That should have been enough without having to flash a kernel but you also need to revert your bootloader to OK1 in order to get Wi-Fi and camera focus.

Following tx_dbs_tx OP implies reverting back to OK1 with Odin BTW. That's a good fallback if you have issues rebooting or other undesirable results. Coming from Lollipop, I'd also recommend the factory reset and wiping everything but ext sdcard if you flash the OK1 stock tar. (Wipe and reset prior so it boots. But follow OP closely.)

The issues you had earlier, was it continually popping up a reboot prompt and get worse after factory reset? I think I know what that is: ItsOn saying hello in a bad way. If you had flashed a custom ROM after updating, you might have avoided that but rooting stock and flashing custom kernel requires ItsOn to be removed.

Edited some comments out. I may have misread initially.
[Sprint  Galaxy Note 4 Android Development] Consumers:
Sorry. Should've made it clearer--it is literally just a brick currently. After the initial failed boots, the device does not respond to the power button at all (no signs of mechanical power button failure and three healthy, charged batteries). No luck even getting a bootloop or getting back to recovery or download mode. The "random reboots" I referred to were hard crashes, the device randomly shutting down and restarting during normal app usage. I thought these symptoms only popped up since only a couple days ago, but I remembered the original reason I was digging up logs was to try to troubleshoot increasing occurrence of device crashes. It was simply accelerating at an extremely rapid pace over the past few days.

To elaborate on the day's events leading up to failure: after shutting down while running dumpstate, logcat, etc., I could only boot to the splash where it'd get stuck. I did notice a red error message about "emmc" at the top-left with some additional details. I didn't stick around to troubleshoot since I needed to fix it in the morning for work, but it does corroborate the idea of eMMC hardware failure that I wasn't aware of prior. I didn't actually flash back to a stock OK1 ROM before reinstalling the ROM since I assumed I was already good to go on the Note 5 port to OK1, so perhaps it actually wasn't the hardware but user error? Otherwise, followed the steps exactly and had a mostly working device for the day except for a few random restarts, but I know everything was fully functional otherwise including Wi-Fi, data, and the camera. Still figured it could be improved that afternoon, so I tried re-flashing the same kernel I had (BeastMode 2.2) without wiping anything. Seemed to help a lot since I didn't crash until the following morning. Randomly shut down without restarting this time, tried booting and I believe it wasn't successful (imperfect recollection here) so I figured I screwed up flashing the kernel so I flashed again wiping Dalvik and cache first. After trying to reboot from this, it was stuck on a black screen for several minutes so I removed the battery. I was only able to get a vibration from trying to boot up once (which got stuck on a black screen again and had its battery removed) before everything failed to respond. No amount of waiting, power draining, charging, battery swapping, or button combos got any screen or vibration response. And, again, no suspicion of button or battery problems coming in, but I did try some of the workarounds for those just in case.

Many possibilities for hardware or user error, so I'd be happy to hear what you think of the symptoms as honestly as I can recall...I can move this to a separate discussion to avoid cluttering this thread if you want to continue. Your advice so far was helpful, though. Thanks! Otherwise, I already sent it off for repair so I won't be able to try any recovery ideas but I'd still like to understand who or what caused it.
[Sprint  Galaxy Note 4 Android Development] samep:
I don't think it's user error. Sounds as you said eMMC failure.

I've seen posts from a few users thinking they resolved these random reboot issues. It almost has us thinking it was a bad flash but later fails again.

Main board replacement or phone exchange may be your option. Take it to Sprint. If it's a brick don't say a lot or mention root. Mainly because the issue stems from updates; it's unknown if rooting had anything to do with that specific hardware failure because there's been others having this issue and never rooted.

Samsung support confirmed to me over the phone that there is a known issue with updates. When I asked for more information on what's being done about it, the tech said I needed to speak with a higher level of support. I was placed on hold and must have rolled past support hours because my call remained on hold too long. No additional info was offered when I called back next day.

I do recall that Samsung support told me that it was both Odin and OTA updates that were corrupting partitions.

I can't recall the site I found the info to ask about but it appeared to be an ongoing issue on a to-do list- to be fixed in upcoming updates. I think it was Data corruption out something like that was carrying over as unresolved. It may have been Odin notes that was looking at. Many things have me wondering why Samsung wants to put an end to rooting their phones; this is one of them. But it could also be exasperated by a bad batch of components or out of spec solder wave batch of main boards. This should be a rare exception if leaked on the real world consumers but depends on Samsung's QA.

The question of failing hardware or corruption during update is not answered for me. I've suggested to others to explain that the problem right after the latest update. My opinion is that we have too many failures in our forum to dismiss as acceptable failure quota. How many are failing that we don't read about here.

Irony or fact? We just had an update. I Odin'd the PG1 update with no issue. I've also not had random reboots unless it was the issue I mentioned earlier. Another reboot issue I had was the phone's case and belt pouch with seat belt secured would cause reboots while driving. Those issues are resolved so not so random for me. My phone only reboots when I want it to.
[Sprint  Galaxy Note 4 Android Development] thereynolds:
Hi, make sure your battery isn't going bad. I started having similar problems after loading this 4our ROM with r56. Random reboots, couldnt boot without charger connected. Got a new battery, everything back to normal.
[Sprint  Galaxy Note 4 Android Development] samep:
Hi, I think you quoted the wrong user. But maybe I left something out?

It's a long post. I addressed my recent random reboots as not so random but explained.

I did neglect to mention this time that my original Samsung battery only lasted about 13 months. At that point, it did shutdown the phone at about 20% capacity remaining. Did it again at 30% while waiting for replacement battery.

An easy tell was to plug in battery charger while powered down on that shutdown. It showed 0%.

Replacement battery has not shutdown the battery. I don't like shutdowns if this nature do feel you did good adding this to the conversation.

[MENTION=4814837]Consumers[/MENTION] should consider battery health as a possible cause of corrupt data; if not already considered. Not a very good battery design but at least removable.

Heat seems to degrade these batteries so I don't even use fast charge and try to avoid leaving on charger any longer than necessary.

How did you make your font Diablo-like? Does it work on MM odexed version too?
[Sprint  Galaxy Note 4 Android Development] Death-Dealer:
Font fix

https://play.google.com/store/apps/details?id=com.jrummy.font.installer

Diablo font has always been my favorite and used it for yrs until I think the note 4 got lollipop. Or maybe I couldn't get this font at all on the note 4 until a couple months ago. I kinda forget when I had to stop using it but I got it again. The main trouble which was a bit time consuming was finding which fonts had to be replaced with Diablo to make all font on the phone Diablo. I don't remember exactly which ones, but it's at least 6 that had to be replaced. And u can just Google Diablo font to get the file for it as well because it's not in the available fonts on font fix. Sorry I don't remember which files to make Diablo, it's been a couple months since I flashed my phone and had to do it, but I had to sit there and redo the fonts anytime I flashed a Rom.

Back on topic..... Wanna report kernel works fine with rooted PG1

Sent from my 0x1 Note 4...... I love tep
[Sprint  Galaxy Note 4 Android Development] mustasusi:
Yes, it applies only for some and not every piece of text. I tried some flashable zips but these prompt an instant error message. If you flashed the font over recovery, maybe you could link me to the file worked for you.

Following the settings you suggested and the CPU heats up like crazy! It easily exceeds the 90⁰ and I do experience occasional reboots too. No min\max freq control and it looks like the CPU is constantly on full stress. Default settings never go above 70⁰ for me. I'm afraid to use under direct sunlight... Any advice as for how to reduce the heat?

This is for Ondemand but I checked interactive as well.
[Sprint  Galaxy Note 4 Android Development] Death-Dealer:
First your phone just might not be able to handle those settings. Second did u also undervolt. I am uv to -40 on all frequencies. I do not get overheating. These are the settings for thermal. If I change the temp to something higher, it messes everything up, so leave that alone, maybe that's ur prob. As for the vdd restriction, when I turn that on the min frequency becomes 1.9. I don't know y, and I wish it didn't, but for me it doesn't eat up any more battery than some other settings I've tried. Leave the gov on interactive unless u have problems.

As for the font, just download a font file. Just Google Diablo font. No flashable file necessary. But to get all fonts changed, u are goin to have a hell of a time. I just picked ones I changed at random and got lucky, now all are Diablo. I know, I know, there are like 100 font files u can change. Good luck
[Sprint  Galaxy Note 4 Android Development] mustasusi:
It turns out that the version of Kernel Auditor I've been using was faking it and -30 under-volt. I took the one came with Freeza's ROM and under-volted by -40. So far so good. I didn't try to higher the temp limit, just lowered it to 50 and noticed nothing. Games tend to drain faster this way but that's because the run smoother with less occasional frame drops. So instead of 6 min/% for MKX I get like 4 min/% (ZL 10,000mah). I guess smooth performance has its price.:good:
[Sprint  Galaxy Note 4 Android Development] shadowcliffs:
Thanks so much for this great Kernel. Just flashed #56 on PG1 Stock deodexed.

[MENTION=2430742]ianmb[/MENTION] thx for the help and suggestion, but I was not aware that tx_dbs_tx had updated his stock roms recently, I was using the ones he had posted initially, so I was not using the current stock roms he has posted.

Because I believe that the previous ROM versions contained freezas first stock kernel for OK1 which was giving issues for some and I think it had SuperSU 2.65-66. Wouldnt hurt to try

Hi,

I assume that the ZL version is for the ZeroLemon Battery, because it's a 10k battery?

If so, what if I have a 10k battery, but it's a different brand? Should I still use the ZL version?

Thanks!
[Sprint  Galaxy Note 4 Android Development] samep:
Yes. The ZL is for all batteries above factory mah spec.
[Sprint  Galaxy Note 4 Android Development] Zeuszoos:
Okay, I'll Calibrate too. Do you know if it's only for battery size? Or were there some other related issues it fixed (if you know)?

Thanks! :)
[Sprint  Galaxy Note 4 Android Development] samep:
It would be the equivalent of the fixes and mods in the kernel without the ZL mod at the time it was released by the developer.

But be aware it's based on the source of original kernel and wouldn't have the security patches that came afterwards.

Developers can update more often than manufacturer but this kernel hasn't been updated in a long time so I wouldn't expect it to have any recent security patches in it, particularly the big ones currently being patched (melt and spectre). I don't think Samsung has patched that Note 4 stock kernel yet.

And the bootloader may yet again get upgraded with a major security update being put in place. When Samsung upgrades bootloader, you cannot downgrade it which makes flashing older stock tars with older bootloader impossible to flash. But you can keep corporate and kernel and flash older custom ROMs or TWRP backups and test for vulnerabilities. Maybe it passes but you would likely need to flash the stock kernel and latest SuperSU zip to get it to boot. You may get MM to boot with this kernel but if security patches are important to you, always test the vulnerability.

Can't say the security patches transfer either with any bouncer and kernel combo, even stock kernel. You always have to test the vulnerabilities yourself. And since the whole OTA update patches the previous update, you may be losing other security patches by flashing older custom ROMs anyway.

Lineage OS, if supported with recent security updates, may be patched and include ZL mod if that matters. But it's been notably buggy on Note devices in the past. I never tried it so maybe it's worth a try; you decide.

Check the development forum later but I don't think Samsung has patched those vulnerabilities in stock yet. You may have to run stock rooted without custom kernel to have most recent patches. That's what I was doing before I upgraded my phone. But again, maybe Lineage OS has a better custom solution and is more stable now.
[Sprint  Galaxy Note 4 Android Development] Zeuszoos:
Thank you for your very informative reply!

Just FYI, I have been running the non-ZL Beast for a little while now (see my earlier post about the issues I'm having) and while it is much, much faster, aside from the issues described, my 10k "iBestWin" battery would run down super fast! Like down to 20% in 3 or 4 hours of just reading on it or something.

I didn't tie the timing of it together until recently though, thinking maybe this new battery went bad or something, because when I first switched to Beast, I didn't notice a rapid drain.

Anyway, once I switched to the ZL Beast today, man what a difference!!! It actually sat at 100% for a while and the drain has slowed waaaaay down!

Thank you very much!!! :)
[Sprint  Galaxy Note 4 Android Development] samep:
The battery capacity should be normal now.

Battery drain can be a mystery but I've had best battery stats with Beastmode and it's generally snappy out of the box, when flashed.

It's best to flash Beastmode over stock kernel because other kernels and ROM developers may tweak the /system/lib/modules. It's also a good idea to backup the original ROM with kernel (system and boot partition) or backup the modules to restore to flash other kernels over original.

Running Beastmode, I generally just disabled the input boost frequency in CPU settings and only slightly over clocked and used under volt conservatively at 20 to 30mV globally. Didn't get too fancy with it but kept the default interactive governor and enabled per core control and MSM Limiter.

In CPU Hotplug, MPDecision was enabled by default so I didn't see any boot options there.

I know some have said they could only run stock kernel so I shared those settings. My phone always did better with Beastmode in daily use, battery stats and performance. Ran cooler too.

I used a modified build of Kernel Adiutor, build 15 is what I currently have but I don't think that's necessary. I believe it had some preset profiles but I never used them long term. Can't comment on those profiles.
[Sprint  Galaxy Note 4 Android Development] Zeuszoos:
I tweaked a few things additional.

Entropy = 1344, 2048 (important)

SD Read = Deadline, 2048 (boost!)

Net = Westwood

Then there's some other settings (I forget the name of the section), like "VFS Cache Pressure", or something to that effect. Dropping it from 100 to 10 makes a nice performance difference!

I only change what I've proved to be beneficial. I can give you a list if you want to try out some changes.

I wasn't aware you could get a custom version with profiles. But you say they haven't made a difference?

Thanks for your post!
[Sprint  Galaxy Note 4 Android Development] samep:
Sure. I can try a list of your settings. Post them if you don't mind. Thanks.

I can't recall the profiles or results that I had but I seem to recall some lag. I think it was profiles like battery, balanced and performance. I didn't stick with anything very long; just went back to my settings. Maybe those profiles could be personalized as well but out of the box, I didn't like them.
