Issue trying to update to 4.3

(Originally posted this in the wrong forum, so I am reposting here.)
I have the Galaxy Note II with T-Mobile.
Some background: It was running Android 4.1.2. I rooted my phone once, about two weeks ago, just so I could take an image of it in case of an update issue. (I think the software was called nandroid.) Once I took the backup, I unrooted it again.
Since then, doing the Software Update check under settings never returned any results. It would just keep checking until I clicked cancel.
Anyway, when T-Mobile released the 4.3 update Monday morning, I tried updating to it using the Kies software on my PC (by connecting it through the USB cable). It got up to about 60% installation and then just hung for over an hour. So I unplugged the phone, re-plugged it back in, and then attempted the emergency firmware recovery through Kies. It went through this and got upto 76% installation and then just hung again for another hour. I again unplugged it to re-try the emergency recovery again, but every time I connected the phone, Kies would not detect it again. I re-seated the battery, rebooted my computer, uninstalled and reinstalled Kies, but Kies would not detect my phone again.
I am/was running the stock rom, but my phone won't even boot into it's normal screen. Any time I turn it again, i see the screen--"there were errors during firmware upgrade. try emergency recovery in Kies."
I can't even figure out a way to get to a screen where I can install the image I took using Nandroid a few weeks ago.
Any help or advice anyone can provide would be extremely appreciated!

Use Odin to fix it.
If you can put your phone into download mode then it should be 'saveable' ..

I am able to put it into download mode. When I follow the instructions I found for Odin, the process seems to go smoothly. However, once my phone reboots, it stays on the "Samsung Galaxy Note II" screen (with the black background). I've left it like that for over 30 minutes, and it just stays on that screen.
Should there be another step I should be following?

Try installing SuperSU from Playstore
It has an option of doing a FULL UNROOT
I am sure that will help.
If not then install Rom Manager from PS
Through RomManager reboot in Recovery
1.) Wipe device 3x times
2.) Wipe cache 3x times
3.) Under advance you will Find Dalvik Cache -- wipe that 3x times

But more importantly why would you want 4.3 stock anyway?
Install TWRP Recovery or ClockWorkMod recovery and install/Flash CM1 (Cyagonemod) or any other custom roms 4.4.x kitkat

Nothing is really working for me.
I can't boot into normal mode. I am able to get into "download" mode, but whenever I try to load an image using the Odin software (both a stock image and a Cyagonemod image), it starts to load the image, but just hangs a certain percent of the way through.
I also can't get to that screen where it gives you the text based options to wipe your device, cache, etc.
I've tried loading both TWRP recovery and ClockWorkMod recovery (through Odin), and though it seems to load properly (Odin says "Pass"), when the phone reboots, it goes to the "Samsumg Galaxy Note II" screen (the one with white text on a black background), and just stays there.
I've gotten T-Mobile to agree to send me a new phone. But if I can't get into any of the items I mention above, how can I make sure my old device is wiped before sending it back to them?

Just do this un root with chain fire root away app.
Then use triangle away app.
Then find 4.1.2 MB1 stock Odin tar. The complete package .
Odin to stock .
Reboot and then update via Ota.
You have to un root first and also have to triangle away which removes flash counter in Odin.
System modified status will not allow Ota.
That's the best suggestion I have

have you tried booting into recovery? after you load the custom recovery with odin and it reboots, pull the battery put it back, then hold vol up + home and then + power. hold all 3 until recovery. try a factory reset and reboot.

I have. It brings me to the same screen with the Samsung Galaxy Note II text on the black background and just stays there.
So, in summary, I can get into download mode (vol down+home+power), but it seems nothing else.

Try factory settings the phone through stock recovery and then check your phone status. It should say 'normal' but if it says 'modified,' download Triangle away and run the tracking setting (it'll make your phone say normal so you can download the OTA). Given you're on tmobile and your phone is the T889 model, check for software updates and install the OTA. Your phone will take a bit and will probably be stuck on the T-Mobile 4G boot screen for several minutes (it's normal). This should work.

Need help, stuck at logo and can't hard reset.

PROBLEM SOLVED.
So at first I used Kingroot to rood my device, and it failed, but then i just realized few days later that Kingroot was installed and used root checker to check and said that it does have root access. After that decided to change the Kingroot to SuperSU by following this video https://www.youtube.com/watch?v=WevWdErXWy4 (It's the SuperSU Me app). I then updated SuperSU binaries and restarted the phone, and now its stuck at the loading screen. I tried hard resetting my phone but it would only show the screen with the android logo and shapes in its belly for about 2 second and go back to the stuck logo screen. Now I'm wondering if there's any fix for it, and if there's no fix then I'm going to try resetting it through this http://lgg3root.com/lg-g3-root/how-to-unrootunbrick-lg-g3/ guide and I was wondering if I should download and use the bell stock factory firmware (I have a virgin mobile version).
Edit: fixed to be more clear.

if you can get into recovery you can probably do it without unbricking. to you have stock recovery or twrp or what? If you have stock recovery then boot into recovery and just run it and itll hard reset your phone, if you have twrp or something just download the flashable rom of your choice (there are stock modded roms too if you like stock) put it on an sdcard and wipe and install that rom.
if you don't know how to get into recovery then make sure your phone is off (if ur not sure do a battery pull and put it back in). hold volume down and power button until the screen comes on. when it comes on let go of vol down and power and then push vol and power again and hold again until you see the writing)
btw if you do a stock recovery hard wipe then you will lose root.

I also faced this problem...

Problem solved. I just flashed the stock firmware onto my phone and it fixed the stuck on logo problem.

At a loss... SM-920P, MM, continuous reboot loop no matter what

I upgraded to MM back the beginning of the month, tripped my Knox bit (I had rooted via PingPong root on Lollipop), but I was eager to go to MM and try Xposed so I could improve the horrible battery life.
I had the system working fine, rooted using CFAR, and no problems. Randomly, about a week ago, it just "lost" root. I wasn't sure why, and CFAR from Odin wouldn't bring it back. I did a flash with SuperSU in TRWP yesterday and it worked, and I did a NANDroid backup, saved it to my computer, and installed Xposed... On a stock ROM.
And my phone has been a continuously rebooting brick ever since, no matter what I do.
So, I've tried everything I can think of. Because my data was completely backed up, I did a complete wipe, and nothing. I tried flashing the Xposed-uninstaller.zip and that supposedly worked, but the phone reboots about 53 seconds after it starts up, continuously, no matter what.
I've tried the default MM firmware, tried letting it go through it's paces on its own (but it just reboots every 53-57 seconds), and also tried with a fresh clean default MM ROM, which does dump TRWP, then restart into the default bootloader, have it dump the cache and do a complete re-wipe, and nothing. Still restarts.
With the stock MM firmware load, the first boot it always stops at 32%, reboots, and when it comes back up it sometimes makes it through "optimizing xx of 30 applications" but always reboots and comes back to it over and over, ad infinitum. Sometimes it makes it to 30, usually it doesn't, but it always fails, reboots, and comes back to the same menu on a stock ROM.
ADP and MTP in TRWP work fine, and all my data is backed up. So, I'm willing to do anything to the device; nothing left on it to care about (I already tried NAND erase in Odin and format partitions in TRWP). It still continuously reboots at around 53 seconds.
I've also tried custom ROMs loaded up from TRWP (Renegade 1.1 and TeamSPR V3). They apparently load - everything looks/works great from inside TRWP - then invariably they reboot at about the 53 second mark. Can't even get Renegade past the boot screen.
Nothing was done hardware-wise to break it; the Knox bit flipped three weeks ago, and the SuperSU upgrade had been working fine. The action that killed it was attempting to install the Xposed framework on a default ROM that only had SuperSU installed. But I've since installed a default ROM and ran the Xposed uninstall to no avail. The uninstall Zip in TRWP gave all the right responses that it worked, but it still rebooted 53 seconds after restart. Continuously.
I don't even know how to go back to Lollipop because attempts to load G920PVPU1AOCF in Odin gives me an immediate failure of "SW REV. CHECK FAIL. DEVICE: 3, BINARY: 1," so downgrading appears to be out of the question.
Someone has to have seen something like this before or there's something I'm missing. About the only thing I can think of is to try a custom ROM install and force the Xposed framework again without even letting it boot up (because it won't anyway) from a TRWP install. I'm going to attempt that while hopefully someone else comes up with ideas for me...

rebooting
people have had luck letting their phone battery die completely and rebooting after charging just a little bit. make sure its completely discharged before rebooting

Stick it in Odin mode and let it die, once it gets to the point where you cannot turn it on anymore, it's good :good:

Bootloop from hell - messing around with kernels

Hi folks,
I had my G920P on PB6 base, with TWRP from here; http://forum.xda-developers.com/spr...nt/tool-utility-twrp-3-0-0-1-teamwin-t3335260, and installed TeamSPR 3.6 ROM (http://forum.xda-developers.com/sprint-galaxy-s6/development/teamspr-rom-v3-t3380648). All was running dandy.
Then one day, I flashed @tdhite 's SkyHigh kernel (v3.2, can be grabbed here; http://forum.xda-developers.com/sprint-galaxy-s6/development/kernel-skyhigh-mm-6-0-1-kernel-t3350673). All was smooth.
Then I wanted to revert back to the default kernel that shipped with TeamSPR ROM, so extracted the boot.img from the ROM zip, and used Flashify (got latest from the Play Store) to flash it. This is where things went downhill.
Upon rebooting, and entering recovery, nothing happened. I don't recall what happened at this point (whether I rebooted, or went to flash SkyHigh zip again, because I was panicking?), but upon attempting to reboot, I entered this bootloop from hell, in which the ROM would not get past the "samsung" screen (I am assuming the equivalent of the Sprint LTE screen, since the TeamSPR ROM replaces that with the international screen :good.
In desperation, I booted into recovery, made a nandroid backup, and took out everything I wanted out of the device.
Then, I went here; http://forum.xda-developers.com/spr...ide-links-files-update-root-restore-t3366862/
got the latest (PF4) TAR (yes, MD5 checked out), wiped the phone from TWRP (system/data/cache/internal storage), and ODIN-ed that.
According to ODIN, all went without a hitch.
When the phone rebooted, it went into stock recovery, and it displayed a "applying update" message, followed by "erasing...", and then "applying update". And then, abruptly rebooted itself.
Bootup now went to the Sprint logo, and then "optimizing apps" green/teal screen (it optimizes 32 apps, for whatever it's worth). Almost instantly after the 32nd app is "optimized", the phone reboots again, and this bootloop restarts.
If I broke the loop by going to recovery (still stock recovery at this point), I am greeted again with with "applying update" message, but then I get the dreadful android with an exclamation point sign on top, undoubtedly having failed to apply whatever updated it was trying to do.
Pressing the power button at this stage, gets me to the stock recovery.
Here, I wiped cache, and did a factory reset. Both yielded no different behavior upon reboot from what has been outlined post-ODIN flash.
(I have tried versions 3.10.6 and 3.11.1 of ODIN, by the way - same result).
I got the latest TWRP available (link posted here; http://forum.xda-developers.com/spr...ide-links-files-update-root-restore-t3366862/), wiped system/cache/data/internal storage, and installed TeamSPR ROM (but not their 3.6 OTA). Rebooted the device, but the device goes into bootloop again on the flashing "Samsung" screen, so back to square 1.
At this point, I am not sure what else to try. The phone is a paperweight at this point, and I am really hoping for it not to remain as such.
Ideas?
Thanks in advance!

Everything you have said is normal. EXCEPT rebooting after optimizing apps.
What I suggest, is power down phone COMPLETELY via TWRP. Boot phone to download mode. Flash PF4 TAR.
Let it do its thing, including rebooting to recovery to apply the update. But pay close attention!! After it shuts down to reboot to Android, interrupt it and go straight to recovery. Then WIPE data/factory reset from stock recovery.
Then reboot to Android.

You have to let it die completely, and when it does die boot into download mode continuously until it wonr anymore (completely dead), and charge until 15% (incase u have to try again). Should b fixed

The post above (assuming this gets there in time) about killing the battery and restarting is correct (generally).
But what you did was not correct (in the quote). You cannot simply pull a boot image, restore that and presume that's enough. The reason is at boot, before selinux is turned down to permissive (init.d processing usually), your file contexts will likely not be correct. There are many commands in the flash updater-script handlers that fixup the permissions to match the ramdisk used. Additionally, there will probably exist inconsistent init.d handling, or otherwise none at all (i.e., with a stock boot.img).
My Skyhigh kernels generally fixes up the permissions in updater-script, even for ROMs that did not set up their initial files contexts correctly, so things will be smooth as you note. Going back to an improperly formed kernel flash, or just pulling the boot image and forcing it into place is not a good idea in general. Flash the full kernel flash next time so it can do its work. Or ask for help first -- we can get you settled.

Let ur s6 die meaning go to odin mode let it sit for hours until it auto shuts off ..while off plug in cable charge to about 10% plug off cable go into recovery first wipe data and cache n restart ...and wallah ur phone is fixed ...hit like it will help...100% this will work on ur phone

If I broke the loop by going to recovery (still stock recovery at this point), I am greeted again with with "applying update" message, but then I get the dreadful android with an exclamation point sign on top, undoubtedly having failed to apply whatever updated it was trying to do.
Pressing the power button at this stage, gets me to the stock recovery.
Here, I wiped cache, and did a factory reset. Both yielded no different behavior upon reboot from what has been outlined post-ODIN flash.
(I have tried versions 3.10.6 and 3.11.1 of ODIN, by the way - same result).
I got the latest TWRP available (link posted here; http://forum.xda-developers.com/spr...ide-links-files-update-root-restore-t3366862/), wiped system/cache/data/internal storage, and installed TeamSPR ROM (but not their 3.6 OTA). Rebooted the device, but the device goes into bootloop again on the flashing "Samsung" screen, so back to square 1.
At this point, I am not sure what else to try. The phone is a paperweight at this point, and I am really hoping for it not to remain as such.
Ideas?
Thanks in advance!

Hey bud thats that constant rebooting issue yes it reboots about ten times before it can optimize those apps then if u do get to start up itll still reboot every min right. well let it die completly man die so much it wont turn on at all then plug it in aand turn it on bingo

I'm not sure if anyone mentioned this but there is a Soft Power-Off(basically the same effect as pulling out your battery) on a Samsung Galaxy S6. All you need to do is Hold volume down and the power button.

The post above (assuming this gets there in time) about killing the battery and restarting is correct (generally).
But what you did was not correct (in the quote). You cannot simply pull a boot image, restore that and presume that's enough. The reason is at boot, before selinux is turned down to permissive (init.d processing usually), your file contexts will likely not be correct. There are many commands in the flash updater-script handlers that fixup the permissions to match the ramdisk used. Additionally, there will probably exist inconsistent init.d handling, or otherwise none at all (i.e., with a stock boot.img).
My Skyhigh kernels generally fixes up the permissions in updater-script, even for ROMs that did not set up their initial files contexts correctly, so things will be smooth as you note. Going back to an improperly formed kernel flash, or just pulling the boot image and forcing it into place is not a good idea in general. Flash the full kernel flash next time so it can do its work. Or ask for help first -- we can get you settled.

The letting it die has done it. I am still not sure why it worked, but I am really glad it did. Thank you!!!
RE: writing boot.img into BOOT partition manually. Yeah, not the best idea to go about it (to put it nicely ). My line of thinking was, any file contexts would have been set by the init.d scripts that run as a result of your kernel having been previously flashed. Clearly, I paid for this assumption with an entire day of panic. There's so much I still have to learn about kernel development, and especially for our devices.

I did do that multiple times, to no avail.

[GUIDE][ROOT][Magisk v20/v19.3] Samsung Galaxy A50 ( Update 12.11.2019 )

Magisk v20 worked stable on Galaxy A50 but If you want to use Magisk v19.3 you can patch and downgrade it using Magisk Manager - Custom Channel Update https://www.youtube.com/watch?v=vcF0pfdQyW8
-----------------------------------------------------------
Complete Guide for Rooting Samsung Galaxy A50 using Magisk v20 / v19.3 ( tested on SM-A505F ):
* Download the firmware Galaxy A50 (SM-A505F).
* Unzip the firmware and copy the AP tar file to your device. It is normally named as AP_[device_model_sw_ver].tar.md5. Copy AP tar file and MagiskManager apk to your phone.
* Install Magisk Manager on your phone.
* In Magisk Manager: Install → Install → Select and Patch a File
* Select the AP tar file. Magisk Manager will patch the whole firmware file and store the output to [Internal Storage]/Download/magisk_patched.tar. Copy magisk_patched.tar the tar file to your PC
* Enter Download Mode : Turn Power Off. Press and hold Volume Up key + Power Key,* When Samsung Logo appears release Power Key only, keep pressing Volume Up key until Android Recovery Mode Appears.
* Select Wipe data / Factory reset, Select Reboot to bootloader.* Connect your Samsung Galaxy to PC using USB Cable.
*Flash magisk_patched.tar as AP in ODIN, together with the BL, CP and HOME_CSC files. Never flash only an AP file, as Odin can shrink your /data file-system if you do. Checked "Auto Reboot" and "F. Reset Time" only in options.
* Magisk is now successfully flashed to your device and Rebooting!
* After the device is booted up, do the usual initial setup. It need more time and patient.
* Connect the phone to Internet copy Magisk Manager apk to your phone and Install it
* Open Magisk Manager. It will ask to do additional setups. Let it do its job and the app will automatically reboot your device.
* Done! You can use Root Checker to check it, Enjoy!

thanks i rooted latest stock F2 firmware

Oh I wish I could get magisk on my phone. Unfortunatly I can't find the firmware, for my phone, anywhere on the internet (A505W). Will do directly once I can!

I had it finally rooted like this since yesterday thanks to this process. Got it in root mode running today all day. THE PROBLEM IS: It doesnt stay on anymore after i reboot once again. It starts, I can put in the pincode of sim, but after 10 seconds it reboots. Without sim also reboots after 10 secs. This goes on and on and on. I read on web delete cache can help. I can sometimes boot normally once thanks to that. Root mode is hopeless, then it always reboots. I used the right stock rom. Didnt make changes of system apps etc. I havent tried factory reset yet, but i'm tired of reinstalling all apps and settings again and i asume it just will happen again. Who knows what is causing this?
Edit: It kept rebooting in any way. Used the factory reset at the end. Booted it up once without root. Set up Wifi and google account. Tried to reboot in root mode and voila: stuck in bootscreen with red letterd 'custom binnary not allowed'. Can't startup, can't go to recovery, can't flash the magisk patched zip (same red letters). Flashed stock rom and wait for the possibility to flash magisk patched again.
Edit 2: Booting in the stock rom probably registers something to let u flash something else again. Magisk patched flashed again. Booted normally, magisk up to date and working. Just gonna install fake gps, smali and magisk hide app again. Not in the mood to test reboot then again. It probably fails again. But i can spoof again for now.
Edit 3: After trying some more things, I think the conclusion is: U can only use Root mode once with this, until it reboots.
I wonder if I'm the only one with this.

I have tried everything but failed, I have tested on some device but it's only happen to A50

That's seem pretty unstable as it is right now. Was tempting to try this on my A505W, but I'm reluctant now.

Now I'm just wondering why the heck my root is still active with 2 random reboots. Last 20 runs the random reboots made it lose root and got stuck with constant rebooting.
When i started the recovery of samsung backup, it rebooted again (3rd time) (again root is somehow still active). Screw it, gonna forget about the backup and keep it like this. I think the random rebooting seems to happen often when installing much apps.

Read my First post, I have updated it for fixing lost magisk root after reboot

I cannot pass through the flashing of image modified by Magisk. During the flash some red text appears on top saying that custom binary (VBMETA) blocked ... then there is a front camera, so I can not read it all and then "Lock" word. The flashing stops and odin waits forever. The only thing I can do is to interrupt and then reflash the whole firmware with odin since it ends up at the "error has occured while updating the device software".
My device is SM-A505FN, firmware XEZ-A505FNXXU1ASE3, OEM unlocked, tried Magisk Manager 7.3.2.

Flash whole stock rom. Boot and login. Connect to wifi. Wait few minutes. Flash magisk rom again.

So what would happen if, by a mistake of mine, my battery dies. Do I have to reflash magisk again and factory wipe everytime? Or is the problem occur only with the "reboot" function of android since it work while fully powering it off.

Mine is still rooted since friday. It sometimes reboots randomly. Then i have to reset with volume down and power button or else is keeps restarting. Root is still active then. Battery also died yesterday. Could start up with power key only and root is still active. I still don't understand why but im good.
(I used the root mode function with volume up and power key till logo popsup only once after the flashing of magisk patcher to let it install magisk manager. )
I'm still wondering if I'm the only one with random reboots or constant reboots

Worked great for my SM-A505G.
In summary, after installing Magisk:
(Powering up normally) → (System with NO Magisk)
(Volume UP + Power) → (Splash screen) → (Release all buttons) → (System with Magisk)
(Volume UP + Power) → (Splash screen) → (Keep pressing volume up) → (Actual recovery)

Hi there,
Yesterday I rooted my A505W (Canadian Variant) and got random reboots like almost every one else. It got so bad, I decided to go back to un rooted stock. Before flashing stock firmware I took a look in build.prop file, hoping I might find something that does not belong there after rooting. And I think I found it. At the very end there is line like this:
ro.expect.recovery_id=0xf1dee4214a6ffec6b8
2cec9a13222d4f34c7fd10000000000000000
000000000
Comment it out to lool like this:
#ro.expect.recovery_id=0xf1dee4214a6ffec6b8
#2cec9a13222d4f34c7fd10000000000000000
#000000000
Wanted to delete it, but it was enough to comment it out whit #
Since last night I don’t have any reboots, it looks like commenting it out did the trick. So try it for yourself an see if it helps.
One more thing, if you need to reboot your device do not do it from Magisk, because it will keep rebooting, just power down and boot with the key combination. As I said since last night I have no random reboots.
