so i recently dove into rooting my s4 after first spending a lot of time reading this great board, thought i had a handle on it, thought things were going very well, but i've hit a snag, which came while attempting my first restore - i'm hopeful someone will give me a little help,
a little background:
1. before rooting i backed up my phone with titanium, also backed it up by copying all of its contents to my pc.
2. i followed the excellent "[SGH-M919] CF-Auto-Root" instructions and it worked without a hitch, it was a quick and easy process, no surprises.
3. confirmed that i was rooted using "root checker", all systems were go.
4. once the root was done i made another backup using titanium and sms backup. i also made a full system backup using online nandroid pro and, to be extra safe, i also backed up efs using efs backup tool.
5. i then moved some folders and files to my external card and once again backed up my phone as before, including to my pc.
6. feeling confident that i could now restore my system to its rooted stock state if things went south, i decided to flash my first rom with cwm, i went with cm11 m7 4.4.3 - i saved the cm11 and gapps zips to my external card using rom tool box pro, rebooted into cwm recovery, selected the two files, and flashed. i also did a data and cache wipe before doing so.
6. needless to say i was thrilled when cm11 loaded perfectly, it worked great, and it was just what i was hoping for.
7. having been bitten by the apparent ease of flashing roms, i decided to restore my system to it's pre cm11 state, to it's rooted stock rom state, and try another rom, rather than just flash another rom from cm11 - i wanted to make sure that returning to my rooted stock rom state would be a simple matter.
and that's where i've run into problems.
1. as i mentioned i made two system backups of my stock rom before flashing cm11, one right after i rooted my phone, and one after moving some folders and files to the external card.
2. after doing a wipe, i chose to restore the second backup, the one i made after moving files and folders, and it didn't quite work out - everything appeared to restore perfectly, but my device was immediately inundated with pop up warnings about stopped apps, i also got a persistent warning that the system had stopped responding as well, prompting me to choose between "wait" or "stop it". not only was the restored backup mired in popup screens, but it was impossibly slow, impossibly "laggy".
3. so i decided to restore the other stock backup, the one i made before i moved folders and files, and the results were the same, pop screens for apps not working, system warnings, severe lags, etc., identical to the first backup.
then i panicked.
1. i decided to flash my phone with the "[SGH-M919] CF-Auto-Root" file again, again with odin, hoping that it would put me where i started - i didn't stop to think that my phone was already rooted, that the file was was for unrooted phones.
2. not only did the reflash not work (my phone just booted as normal, as if the flash didn't get a chance to finish), but cwm recovery in boot mode was gone, replaced by what appears to be the andorid stock recovery screen, a screen with an animated dying/collapsing robot, - the screen was titled: "android system recovery <3e> and asked for an "update" from the external storage or cache.
3. not knowing what "update" it was looking for, i selected a backed system files (the first rooted stock rom backup i made, the second rooted stock backup i made, and even the cm11 file) - none worked.
4. i then downloaded a clean stock rom from cwm's website, converted it from zip to tar, and tried to flash it using odin with my device in upload mode, it didn't work either.
so how badly did i mess up my phone? any help would be greatly appreciated.

If it boots at all you didn't kill it.
Not sure what rom you got from the CWM site. They do recoveries, not roms. The ROM manager app does allow you to download roms, but you can't just convert those from zip to tar. That doesn't make them flashable in Odin.
Here's what you do. Get the stock ROM from either here on XDA (use the search feature to find it) or from Sammobile.com.
Flash that in Odin.
Then you can start over.
---OR---
If you want to try to fix what you've got now, download CWM or TWRP RECOVERY (nor ROM) and flash that in Odin. Boot to recovery, wipe data and system, and flash any other rom you want. That will start you over with a fresh rom of your choice.

my apologies, i meant that i downloaded recovery files from the cwm website, not a rom files - i got them from https://www.clockworkmod.com/rommanager - i downloaded both (touch & non-touch) s4 t-mobile versions (6.0.4.7). i'm assumed those were recovery files?

again, my apologies - i meant that i downloaded *.img files, not zips, and converted them to tars for odin use. i used a batch file to convert them from img to tar, found at xda, here: http://forum.xda-developers.com/showthread.php?t=2281287 - it seemed to do the job, odin ran and reported success. wrong files? wrong conversion?

given a choice, i'd like to do what's bolded in red - but that's what i thought i was doing by flashing the cwm file i downloaded from the cwm website - but after the flash attempt it wouldn't boot into cwm, it would just boot into (i'm assuming") the stock rom i restored, which was a mess. i also unchecked auto-boot to see if that helped - but when i manually booted it didn't boot into cwm, it booted into the stock recovery, with the animated android.
i'll try downloading cwm from the sources you provided, and see if that does the trick. btw, why do you think i was able to flash the cm11 rom with (seemingly) perfect success, but wasn't able to restore either one of the full system (android) backups i made after i rooted my phone?
anyway Skipjack, thanks a ton for your assistance and i'll report back after i give your sources a try. fwiw, it sure is a great charge when a newbie like me sees a custom rom load for the first time, displaying a new ui as it boots, fun stuff.
Just download the ready yo flash tar files. Cwm has them. Twrp has them.
success Skipjack thanks to your generous time and assistance!
i ended up downloading the latest odin zip i could find and philz_touch_6.08.9-jfltetmo.tar.md5... my first try didn't take, with auto-reboot checked, my phone simply rebooted into the same problematic rom i had restored. i then tried it with auto-boot unchecked and manually booted when odin reported pass/success, and it worked. what struck me as odd was how long it took to flash, to report pass/success, around 3-5 minutes if i had to guess, a big difference compared to when i first used odin to root my phone with the["SGH-M919] CF-Auto-Root *.tar.md5 file - i'm guessing that's why it didn't work with auto-boot checked, just took too long?
anyway once i booted into philz_touch recovery i executed the wipe data/factory reset > clean to install a new rom command and then flashed the cm11 m7 (snapshot) rom, which i had flashed once before, right before i attempted to restore the stock rom it had replaced. and as was the case the first time around, it installed without a hitch and is running smooth and fast.
however now when i boot the phone, as soon as the cyanogen logo appears, very tiny text appears in the upper left hand corner which reads (i had to use a magnifying glass!) - it doesn't seem to effect the performance of he device but i'd like to get to the bottom of it, i've already searched and it appears to be a rather common issue.
kernel is not seandroid enforcing
set warranty bit: kernel
btw, i forgot to mention, when i purchased my sgh-m99 it already had 4.3 installed - when i flashed my first rom (cm11 m7) it included kitkat 4.4.2... could this be what caused my problems? did trying to go back to (restore) a 4.3 rom after flashing a 4.4.2 rom screw things up? can this even be done successfully?
and finally, at the risk of bugging the heck out of you, what roms do you prefer for your s4, assuming you have an s4? do you like aosp roms or touchwiz? does one type have a better reputation of being more stable? the primary reason i wanted to rot my phone was to get rid of a bunch of t-mobile / samsung bloatware, which i thought i could do by installing a lean custom rom. any suggestions, which are your favorites? thanks again Skipkack.
ouhned after
re the two lines of text i now get in the upper left hand corner of the screen whenever i boot, the kernel message:
kernel is not seandroid enforcing

well after a lot of searching and reading, including coming across dozens of "fixes" and "solutions" that didn't seem to work for many folks, these two responses seemed to make some sense, what do you think?

The tiny text on the boot screen is basically telling you that Knox has been tripped. You are right. It does not affect the performance of the phone.

thanks skipjack... btw i'm really liking the cm11 m7 rom but, via the learning curve process, i've discovered it does not support wifi calling, something that apparently all aosp rom lack, guess i'll have to go with a touchwiz rom even tho the selection seems to be few and far between. also, is it possible to revert back to 4.3 once 4.4.2 has been flashed? seems like there's a lot of mixed opinions on this, altho in terms of those opinions it's hard for me tell who the pros are that should believed, and who the other guys are that really don't know. thanks again.

Once you are rooted you can flash any custom ROM 4.3, 4.4, 4.2, etc. and then go back to stock 4.3. And only TW ROMs allow wifi calling

very interesting... i guess i misunderstood the posts i read on the subject, maybe they were discussing whether or not you could revert to 4.3 from 4.4.2 on non-rooted phones, which i'm guessing isn't possible. anyway, as i mentioned previously, i fist rooted my 4.3 phone, did a full system backup (using online nandroid), flashed a 4.4.2 rom which worked perfectly, then tried to restore my 4.3 backup only to encounter a bunch of problems, thought going from 4.4.2 back to 4.3 may have caused the problems but i guess not?
so if i'm using a 4.4.2 custom rom and want to restore a 4.3 backup i should be able to boot into recovery and restore from there? or would i need to do a 4.3 flash first, before restoring a 4.3 backup?

Did you wipe before you restored? And do not misunderstand this, you cannot downgrade firmwares once you go 4.3 and up, but you can downgrade the system, which is what you did with your backup

thanks very much for the clarification, i was under the impression that firmware and system were somewhat synonymous in this context, i.e. if you upgraded firmware you were in effect upgrading the system, but i see that's not the case, again thanks. and yes i did do a full wipe before trying to restore the backup, was i not supposed to?

Updating firmware does update the system. Based on your previous comment the only thing you did was update the system by flashing a ROM which only contains the system, data, and kernel, so you can still flash the 4.3 firmware. Firmware consists of bootloader, recovery, modem, and system, what you cannot downgrade is the bootloader, the flash will fail every time because it will try to downgrade it. And you should not experience any issues restoring your back up. What were this problems?
btw serio22, do you have a favorite tw rom?
Yea serio22, what is your favorite TW ROM?

but the cm11 rom zip i flashed included 4.4.2, before flashing i was using 4.3 - so didn't i update (or change) both the system and firmware?
btw, fwiw, - now that i'm up and running thanks to skipjacks help, i decided to try restoring my 4.3 backup again. when i tried this in the past it would restore to the same state as it was before but it was virtually unusable because of severe lags and multiple app not working popups that made navigating almost impossible. well now when i try to restore it fails and i get the following message:
checking md summs...
md5 mismatch

update:
well it looks like the *.md5 file was pointing to my internal drive rather than external which is where i had moved the 4.3 backup (and apparently the *.md5 file didn't update or account for the move), anyway i copied the backup to my internal drive and, viola, no more md5 mismatch errors. more importantly, it restored the 4.3 backup perfectly, in the exact same state as before, without all of lagging and pop up issues i was having before, so i'm one happy camper! not sure what i did the first time around, but all is good now, for he time being, sure wish i knew what i mucked up to cause the problems in the first place, i really have no idea, other than being a newbie at this. also, fwiw, the tiny text in the upper left hand corner that appears during boot (kernal message) no longer appears now that i have restored the 4.3 system backup... fwiw2, i'm liking the philz_touch_recovery but it sure has taken some getting used to, the commands are so close together and the thing is so sensitive, very easy to accidentally select the wrong option, and some of the wrong options aren't too friendly if it wasn't what you had intended to select.

I used factory reset and now my phone is stuck at the tmobile logo. I was rooted before but I removed SuperSU before doing the factory reset. I also tried wiping out the data at recovery mode but I'm still having the same problem. Is there anyone that can help me fix my Note 2?

I hope you didn't wipe system my mistake
Wiping /system is a trivial problem to solve, just flash again and voilà.
What are you trying to accomplish exactly? If you want back to stock, flash the appropriate ROM with Odin, boot to stock recovery, factory reset and call it a day. Unless you've messed up your NV items or done something incorrect with the bootloader, that's pretty much all there is to it.
I wiped out the cache partition at recovery mode and now my phone is working just fine. The reason I factory reset my phone because I want to try if the system will let me update OTA after a reset. Unfortunately it won't let me update still because my phone was rooted. Is there a way to bypass this so I'd be able to update my phone?
Ah! Flashing back to a non-rooted ROM would allow the OTA mechanisms to work normally.
There's inherently a risk for a ROM update to patch something that's been modified in ways it does not expect, such as root on a stock ROM.
In the case of Samsung devices, you could always Odin flash back to stock, or a pre-rooted stock image.

Well I've always been on stock. I just rooted my phone before for some apps and that's it. I never use any custom rom. Im still at stock but wont let me update still
Consider yourself as "custom" the moment you change anything on your /system partition, that includes root.
Samsung ROMs have this check that's displayed somewhere in settings, where your ROM will say if it thinks it's been modified. If so, OTA updates will be disabled.
Factory reset alone won't completely unroot you. You must unroot, then factory reset.
At this point, since you just want a stock rooted ROM and have already factory reset, you could flash the latest pre-rooted ROM with Odin. Will probably be simpler than prodding the phone into getting the OTA.
