TL;DR - I found a procedure to system / firmware update stock rooted, without needing to wipe data. Would people find a sort of noob-friendly guide useful? Reading up on other posts through the history of this subforum seem to be filled with misinformation that updating firmware on stock rooted = you will need to wipe no matter what...
----------------------
Hey guys, so I got a really reaaaallly good deal on the Galaxy Tab S6 (NON-Lite), and the nicer variant (256gb storage / 8gb RAM). Combining with 10% rakuten cash back, student discount, referral discount, and a slightly unethical "trick", I essentially bought it straight from the Samsung store for ~$280-$290-ish when all is said and done.
So anyway, seeing as how there's no original / non-stock Android development for the Galaxy Tab S6, I decided to mess around with the stock ROM for our device, the Tab S6 Lite. From the ~2 months I've owned this tablet, I've only used LineageOS. I only ever was in the stock ROM to unlock the bootloader. Literally less than an hour messing with the stock system. So my experience with stock was somewhat limited obviously.
Having read these forums before I bought the S6 Lite, and even now whilst doing research about stock ROM, it seems that the general consensus is that THERE IS NO WAY TO UPDATE THE STOCK ROOTED ROM WITHOUT WIPING DATA. That info was from several months ago, but it still seems that no one has explicitly stated that it actually is indeed possible? Now, I know that when you initially root, you will have to factory reset / wipe data. Also when you unlock bootloader. However, I've seen many posts saying that just to do an OTA update (obviously via Odin, as system update is disabled after root), you are SOL and will need to wipe data again.
Like I said, I have a Galaxy Tab S6 on the way, which only has stock-based ROM's. I'm not even going to use any custom ROM's and will instead go full stock + Magisk, just like I do with my daily driver phones. No TWRP either, encryption left default enabled. Actually, since the HTC U12+, I prefer going stock and no TWRP, relying on adb / fastboot (and in this case, Odin). Magisk and EdXposed bridge all the gaps I need in terms of mods, and I can't beat the stability and retention of all OEM features (as much as I hate Touchwiz... I don't care if it's called OneUI now lol). I figured I would play around with the Tab S6 Lite in order to get used to how I'll be operating with the Tab S6. My last Samsung device was the Galaxy S5 (phone, not tablet. "KLTE" model), and that feels like long AF ago.
--------MAIN POINT STARTS HERE--------
So anyway, back to the Tab S6 Lite - I was messing around with the stock firmware and found that you can indeed install firmware / system updates via Odin on stock rooted ROM, without the need to wipe data. But a lot of old posts, and even newer posts, seem to claim that you will have to factory reset / wipe again in order to update your firmware if you're rooted. Ain't nobody got time fo dat!! Well, I was able to update, without losing data and keeping root, and tested it by updating thru 2 different firmware levels (09-2020 -> 10-2020 -> 12-2020). Just needed to do things in a pretty specific order, but each time Odin flashed the new firmware, the next boot said "Optimizing Apps" or whatever, and I was updated to the new firmware / system update without losing data.
Again, no TWRP, no flashing special verity / vbmeta / etc packages. Just bone stock, Magisk-rooted. Like taking regular system OTA (the tablet being updated itself), but doing it manually with manual steps required.
Hopefully, assuming this will also work with the Galaxy Tab S6, this makes me much more confident that I can have a nice and smooth experience when I get the new tablet in.
So - my big question, especially to those who are more involved and/or have been around this subforum for more than me - were you guys already aware that it's indeed possible to system / firmware update while rooted on stock WITHOUT wiping data? If not (or even if you did), would you guys find a more noob-friendly guide to be useful or helpful? I just find it very strange that the possibility has been so far dismissed. Wiping data every time you need to update sucks!!
I'd love to hear some feedback... I also posted the bootloader splash warning removal guide over in the Guides subforum, and see a decent number of people have downloaded, but the thread has received no feedback whatsoever. I'm not sure if anybody is actually interested or if it would be worth my time sharing another guide. Anyway, thanks all and stay safe.
EDIT: I just downgraded back to 09-2020 firmware. I'm going to try setting up the tablet in its entirety this time before updating the firmware (last time, I didn't bother signing in and installing my apps and stuff since I was just testing and expecting to bootloop / softbrick at some point). Going to do each release sequentially again. But it's getting late and gonna go to bed for now. Still has another 100+ apps to install anyway, lol.
EDIT 2: Yup, all went good. Magisk 21.4 + EdXposed 5.2.1, a bunch of modules, etc. System updates went perfectly smoothly with no need to wipe. SafetyNet passing, etc.
What was your procedure to OTA update a tablet which is running stock + Magisk?

I've been trying to upgrade to ICS (root or not is unimportant to me) for two weeks. I've followed every instruction, every guide out there and then some. I think I finally backed myself into a corner and don't think I'll be able to get out of it this time.
I have a TPT 64GB WiFi US model. Despite running the thing stock, it simply refuses under all circumstances to find OTA updates. That is, since I have owned it (since 2011), not once has the regular System Update OTA app indicated that there was any sort of update. I even followed all the Lenovo KB articles that tell you how to clear the Dalvik cache, delete stale update files, etc. to try and get it to patch. Nope. It's like my device is some kind of counterfeit that isn't even a real ThinkPad. I am totally at a loss.
So I ended up rooting it to try and force the updates down its uncooperative throat.
I was able to upgrade as far as 0039_0089, but every single time I try to boot up ICS, no matter what guide I followed, no matter whether my bootloader is CWM or stock, no matter whether I factory reset or wipe Dalvik, no matter whether USB charger or devices are plugged in or not, no matter whether I'm rooted or not... regardless of ANY variables WHATSOEVER, the thing just boot loops as soon as it tries to boot ICS.
I spent 24 hours trying to stop it from boot looping when it boots ICS. Things I've tried:
Tried some guy's "no-bloat" nandroid backup of 0039_0089, then to ICS after restoring stock files, using CWM with the removed asserts
Tried GodfatherIP's nandroid of 0039_0086, upgrading to 0039_0089, then to ICS using CWM with the removed asserts
Tried returning to stock recovery, which at first resulted in having no recovery kernel at all, but eventually I somehow managed to get stock recovery back, and had a non-rooted stock 0039_0089 based on GodfatherIP's nandroid plus the stock upgrade to 0039_0089
Tried installing the unmodified A310_0069_0130 on top of the above, using stock recovery, and it seemed to upgrade without a hitch
Rebooting, power cycling, wiping cache, and/or factory resetting had no impact on the ability of the above image to actually boot
Tried installing the unmodified A400_0069_0130 on top of the above, using stock recovery, and it seemed to upgrade without a hitch
Rebooting, power cycling, wiping cache, and/or factory resetting had no impact on the ability of the above image to actually boot
Basically, every single last thing I've tried has resulted in an utter failure to boot ICS -- not even once -- under any circumstances. I don't think I'm missing anything; I've literally followed instructions step by step. And just in case 99% of the developers/guide-posters got it wrong, I've followed at least a dozen guides, so statistically at least one of them is bound to be right, right....? Well, apparently not?
Right now I have a boot-looping system that's been factory reset and cache wiped, with stock recovery. All I can do is attempt to apply signed updates. I obviously can't go back to a nandroid backup.
Do I have any recourse at all, or do I have to throw my $600 unit in the trash? Right now it's basically only useful as a cutting board. I can't believe this has been so excruciating -- never in 3 years of rooting 10+ Android devices have I ever experienced anything this awful. And the problems are compounded by the fact that most of the guides out there are only for ROW or UK, leaving US devices in the dark / untested, so that may be one reason why I'm having issues.... probably nobody has even tested their methods on US builds except GodfatherIP, but even his methods proved futile for me.
I just want ICS... a unit that works... root is completely irrelevant to me, it always has been. But between the out of the box updater being completely and fundamentally broken, and the utter failure of all rooted attempts to upgrade to ICS, I am at wit's end.
Am I the only one experiencing this or has anyone overcome a similar situation?
I have been running CM (currently CM11) on my SGS4 since I bought it from Sprint in summer 2013. However, Sprint changed their international partners pretty seriously in the past 2 years, so I *really* need a PRL update for international travel. Normally the easiest way to do this is to reboot to stock or TriForce, run the "update PRL" and "update Profile" options from in TriForce, and go on with my life.
But I encrypt my phone. So I had to boot into TWRP, wipe and format *everything* and make sure the phone came up unencrypted in CM. All is OK.
So I reboot, flash TriForce 5.4 custom with stock (not KK) kernel. Flash works fine, I reboot... and am prompted to decrypt the device before I can do anything. None of the decryption passwords I've used in the past (I checked my password safe) are working. When I flash back to CM, it boots fine, and the settings says that the device is not encrypted.
I downloaded and tried TriForce 5.2 and 4.0, both are giving the same problem. I have used TriForce in the past on this phone, so it SHOULD be fine....?
Someone in #twrp said that the location of the encryption key changed from Android 4.4 to 5.0. So my only remaining thought now is that there was also a change from 4.3 to 4.4, and the encryption key for 4.3 didn't get removed in the wipe, and since the partition is NOT encrypted, the decryption, even if I have the right key, fails, so I can't get into the phone. Hope that makes sense.
Anyone have any guess better, or, if I'm right, know what I need to move/edit to fix this?
Followup: IRC #sgs4 suggested a full install of stock via odin, so I'll be trying that on Saturday, after I can get a new stock rom downloaded overnight. if there are thoughts before then, I'd love 'em.

Followup - this was never solved before I dropped the phone and shattered the screen (literally days after this post). So if someone runs into the same thing... good luck.

Thanks for the update, I was actually going to suggest stock ODIN instead of TriForce, but you are saying it did not work ? It's good to know for the future. I was initially going to encrypt my phone a long time ago, but I had concerns about decryption when switching ROMs.
My question is why the encryption was not removed after the format ? I've used TWRP to pretty much hose out everything inside the phone, so it's possible the encryption location is located somewhere else. I came across this article:
http://money.cnn.com/2015/05/21/technology/resell-android-phone/
So I guess even after a complete wipe everything ISN'T removed. Maybe your encryption was also stuck as well.................................... What new phone are you getting ?...................................

I was never able to get the stock odin download. The whole problem came up because I was going overseas... I got around it by just buying a local SIM rather than using the Sprint roaming (again, I was doing all this just to update the PRL. new GSM SIM = no PRL update needed). On the way home less than a week later, I cracked the screen so bad the LCD and backlight wouldn't even go on.
I replaced it with a Nexus 6. A bit big, but it doesn't suffer Samsung software awfulness, so I didn't have to flash it with CM to make it usable.
Hi guys,
Have just spent the last couple of hours trying to research this but still not quite sure what's the best (safest!!) way of upgrading to lollipop on my SM-910G. I am rooted and currently on 4.4.4 and when I try to do an OTA update, I get the msg "The operating system has been modified in an unauthorised way.... etc etc"
When I connect via Kies, I get a pop up msg telling me that lollipop is available however when I try to update it tells me that I have to be unrooted. I read an article where some guy messed up his rooted S4 while trying to update via Kies. Can't afford for that to happen on my phone, I've backed up all my apps and data via Titanium Backup but now need to know what the safest way is to upgrade and keep all my settings etc.
I've downloaded the right 5.0 ROM (N910GDTU1BOC5_N910GXSA1BOC5_XSA.zip) for my model - am I correct to say that if I flash via Odin, I will lose all my apps and settings (and root)?
If I want to update and keep all my settings, am I safe to unroot via SuperSU, then update via Kies? I've read about how unrooting via SuperSU isn't really a complete unroot?
At the end of the day unless I'm 100% certain I will probably stay on 4.4.4 since there has been some horror stories with battery drain and stuff on 5.0
Has anyone been in a similar situation?

hi
Just a few points ...First if you " dirty flash" official stock Rom with Odin, then you will lose root ( so to me there is no need to unroot first ) However you do not loose any 3 rd party apps or settings . Also i never use Kies as my personal experience is that it is a waist of time .Regarding Lollipop well i have flashed several newer " version"/changelog/dated of Lollipop 5.0.1 over the past months and all of them have been good to me...( ..overall.) No real battery drain ,no lag ( only recent button and one " Samsung bug in the setting " Accessibilty" .
All my "problems " on Lollipop, on and off, was caused by 3 rd party apps
eg.Past few days i had suddenly random reboots over and over .i reflashed Lollipol ,i factory reset ,but the random reboots continued .
i then started to install all my +_ 162 ..?? apps one by one and checked
Eventually found my culprit ..'Greenify " (the experimental paid ,bolt on package, which is meant mostly for Xposed module with few functions you can also use without Xposed eg "don't remove Notifications " and Greenify system apps l)
After using Greenify for months with no issues it suddenly started giving problems .
So i could have given Lollipop the blame for my woes but i did not .
Yes I do believe Lollipop has issues ,but overall i cannot complain .
yes ,Titanuim is the way to go .
Also i "unrooted " via SuperUser app once, no problem at all, but then why do this if you just flash over it and root is gone
Bottom line ,
you can be "stuck " on Android v4.4.4 hoping and waiting .......?
or faceup to Lollipop ?
its your choice ?
good luck
Hey willcor thanks for the reply! Good to hear your experiences with this. Interestingly I've had a similar problem of sluggishness, lag and random rebooting (multiple times a day) on my Note 4 running kitkat. This went on for about 2 or 3 days. Tried installing some recently installed apps thinking it might have caused it, and now it seems it's fixed itself, I think??
Even pulling the battery and restarting often took ages to boot. Took my 128GB SD card out and tried to boot thinking maybe it was the card but it still lagged and restarted by itself. Like I said it seems ok now and has been ok for the last few days, but now that you mention Greenify, I have that installed too along with a few exposed modules. This rebooting problem is what motivated me to think about upgrading to lollipop to see if it would fix it.
Going by what you said, if I am not going to lose apps, data and settings, then I might flash to lollipop, then re-root. Sounds like the way to go. Maybe...

hi,
Just a quick remark. When i was on Android v4.4.4, most of my issues eg. Private mode S HEALTH... (yes i know there was quick fixes /patches , that you could apply) Play store not installing apps, lags from time to time etc was caused by Xposed Framework. As far as i can remember Xposed was never optimise for Android v4.4.4? As "good" as Xposed was, it gave me "terrible headache /problems" on my Note 4....... even after uninstalling Xposed it broke some apps functionality! (This is a fact for me) . but yet, on all my other devices, no issues ! As stated in my previous post, that Lollipop experience, has been over all, very good for me.,(I have accepted the few bugs, that comes with every software update be it Android v4.4.4 or Android v 5.0.1.)
Lollipop also enabled me to use other apps /features eg Network Toggle app (change network only to LTE or LTE/3G or 3G only.. root required)
Bottom line
for me is.... yes, Lollipop has issues, but most of mine was caused by 3rd party apps not optimised 100% , work smoothly on Lollipop.
good luck
..............................
post note....
Titanium, i forgot, you might have some minor issues at first. Titanium could not find backup folder on my ext sd same as on Android v4.4.4) , so i used NextApp Sdfix (Play store, free app) Titanium, then was able to locate back ups. Again yesterday, i factory reset my device because of a Nova launcher, toggle notification issue and because i also wanted to for a period of time.
Titanium could not write and above NextApp Sdfix said i had no write premisson after running NextApp. i formatted my ext sd on laptop and NextApp did its work and Titanium working 100%
Just thought to make you aware if issue arrived.
Thanks... I forget all these root features have to be redone. I've also given extsd access on kitkat after rooting. Will have to do it all over again I guess!
Ok just a quick update. Flashed to 5.0.1 with Odin and rooted with CFautoroot. Everything seems to be ok apart from after rooting and rebooting, I got a "could not do normal boot" msg, saying that the phone was in download mode and not to disconnect the target. I pulled the batt and booted up normally ok. Checked in Titanium and found root access ok, activated write to SD and all seems normal.
Things seem a bit sluggish with lollipop, so I uninstalled xposed (which now won't work on this version), greenify and some other apps, and booted into recovery to wipe cache partition. When it was done wiping the cache and said to reboot, I got the same "could not do normal boot" msg. Once again I pulled the battery and it booted ok.
Not sure what has happened or if anything is affected - should I re-flash 5.0 with Odin and re-root all over again?

hi,
i am sure i read somewhere about.re: your remark, when you rooted and got a msg, with
"could not do a normal reboot... I am sure it could be ( @ Chainfire,) Cf autoroot website not sure.?
I would have search for a answer /reason!/ explanation Then i would afterwards, reflash Rom. (depends on you)
Just a quick question.... At what stage did you uninstall Xposed....? before /after flashing etc. i stated before that i found Xposed "broke /caused issues after i uninstalling it. (facts about two or three times it happened , in past )
Also i had no problem in using Greenify again (i have re installed it) its just the donation /paid / experimental package i am a bit hesitant with.
good luck

Hey guys, I have since reflashed and rerooted and now seem to have less problems, although the phone is still sluggish, randomly locking up and restarting , and sometimes restarting to the green android "could not do normal boot" screen.
Question now is, can I boot into stock recovery to do a factory reset? I've done some research but the views seem conflicting. Is this recommended, will I be stuck in a bootloop and will I still be rooted after the reset?
I never did a factory reset when flashing from 4.4 to 5.0.1 so I'm hoping this will fix the issues I've got now.

Good day everyone, i am going to report my delicate and infuriating problem that has been haunting my head for two months
I'll describe my problem in extreme detail, hoping you guys able to identify this disaster.
My android phone is Lenovo A6000 Plus, i've bought it 2 years ago and it's running on latest Lollipop version 5.1.1 I never alter the system files, since i only use my phone for games and communications, and i'm not really into tinkering android's software. so i use my phone like a normal person, do the updates when the settings asked me, update the apps, etc. and this phone running smoothly in my service. i wanted to ask both WISDOM and HELP in this thread.
1. The Bootloop disaster symptoms started on april 2018, when the phone boot SLOWLY AS HELL, seriously.. it took about 1-2 hours to boot, and it also shows the (ANDROID IS UPGRADING 0/132 apps) like wtf? , i haven't update or install any new android apps before this symptom happened. So i leave my phone plugged in and wait it to complete the upgrade; then it worked normally as it should. Unfortunately, it happened EVERYTIME i turn my phone on, EVERY SINGLE TIME.. T_T. so i struggled to avoid my phone from running out from battery as i can. This symptom happened for 3 weeks and it got from bad to worse. I wonder what kind of problem is this?
2. The worse part came when my phone is running at high RAM usage, let's say, i game on my phone alot in my spare time, using the ram up to 1800mb everytime i play game or open chrome browser (Lenovo A6000 plus have 2GB ram). When i close/task manager the apps, my phone launcher wont appear normally as it should (long pressing bottom left button) and it FORCED me to restart the phone and suffer the 1-2 hour LONG BOOT. That's unusual, i cleaned my phone regularly (using cleanmaster) and preserve both of my internal and external storage with 3-4GB free space. I wonder what kind of curse is this?
3. So the bootloop disaster finally got me this May when i turn my phone off and tried to reboot. And... no Android is upgrading 0/132 showed up, i waited for 4 hours and reboot my phone again and again and again. And its finally STRANDED on BOOTLOOP :crying:
Im on panic mode when problem 3 happened, then i searched the almighty Google for help, and found that i can backup my data with TWRP recovery, so i do as it said, followed the guides and BACKED UP all of my data.
For once i felt relieved my data is now saved. Now onto the main problem.
I've had enough of this problem so i format the phone into factory reset, wipe the Dalvik ****s, cache, system and data. All of it. thus, making my phone virgin again.
4. Now im trying to resurrect my phone, and tried my effort by downloading Stock Lollipop 5.1.1 OS again along with its prerequisites. I tried to zip-install it using TWRP but it said that "has not switched carriers and cannot be upgraded" i scratched my head and searched almighty Google again then found that i need to do ####6430### thingy before doing that. umm.. so my phone domain need to be changed, how can i do that with a phone who can't boot? (I'm from Singapore btw). What did i do wrong?? did my phone just turned into useless BRICK? but i've read that bricked phone can't even start the recovery, yet my phone still able to start either with Lollipop stock recovery or TWRP (if i adb fastboot it with adb tools from .cmd), so it's not totally fuc.. uh., BRICKED and i got the chance to fix it.
TL;DR
So, Guys.. i desperately need help. i'm a peon both in work and college, and a dead phone will not make a great company for a person like me.
I searched for enlightments and breakthroughs but always ended up failed resurrecting my phone, can you guys PLEASE :crying: tell/give me a SAFE and WORKING walkthrough to re-install my Lenovo A6000 Plus with Lollipop 5.1.1? And does it running a custom OS like those Cynadrogen thingy is good and worthy enough to speed up my phone? is the chances of getting bricked is unavoidable when running custom OS? I thought its going to be easy like reinstalling Windows, but i was wrong.
FYI, my phone now is UNROOTED and running on TWRP 3.0.2 and i can easily revert it back to Lollipop stock recovery if needed (does it considered rooting if i install custom recovery?) I also need a valid info if my phone would never turn like this again if i resurrect it again.
PLEASE HELP ME PEOPLE
THANK YOU.. ! :highfive:

Good day everyone, i am going to report my delicate and infuriating problem that has been haunting my head for two months
I'll describe my problem in extreme detail, hoping you guys able to identify this disaster.
My android phone is Lenovo A6000 Plus, i've bought it 2 years ago and it's running on latest Lollipop version 5.1.1 I never alter the system files, since i only use my phone for games and communications, and i'm not really into tinkering android's software. so i use my phone like a normal person, do the updates when the settings asked me, update the apps, etc. and this phone running smoothly in my service. i wanted to ask both WISDOM and HELP in this thread.
1. The Bootloop disaster symptoms started on april 2018, when the phone boot SLOWLY AS HELL, seriously.. it took about 1-2 hours to boot, and it also shows the (ANDROID IS UPGRADING 0/132 apps) like wtf? , i haven't update or install any new android apps before this symptom happened. So i leave my phone plugged in and wait it to complete the upgrade; then it worked normally as it should. Unfortunately, it happened EVERYTIME i turn my phone on, EVERY SINGLE TIME.. T_T. so i struggled to avoid my phone from running out from battery as i can. This symptom happened for 3 weeks and it got from bad to worse. I wonder what kind of problem is this?
2. The worse part came when my phone is running at high RAM usage, let's say, i game on my phone alot in my spare time, using the ram up to 1800mb everytime i play game or open chrome browser (Lenovo A6000 plus have 2GB ram). When i close/task manager the apps, my phone launcher wont appear normally as it should (long pressing bottom left button) and it FORCED me to restart the phone and suffer the 1-2 hour LONG BOOT. That's unusual, i cleaned my phone regularly (using cleanmaster) and preserve both of my internal and external storage with 3-4GB free space. I wonder what kind of curse is this?
3. So the bootloop disaster finally got me this May when i turn my phone off and tried to reboot. And... no Android is upgrading 0/132 showed up, i waited for 4 hours and reboot my phone again and again and again. And its finally STRANDED on BOOTLOOP :crying:
Im on panic mode when problem 3 happened, then i searched the almighty Google for help, and found that i can backup my data with TWRP recovery, so i do as it said, followed the guides and BACKED UP all of my data.
For once i felt relieved my data is now saved. Now onto the main problem.
I've had enough of this problem so i format the phone into factory reset, wipe the Dalvik ****s, cache, system and data. All of it. thus, making my phone virgin again.
4. Now im trying to resurrect my phone, and tried my effort by downloading Stock Lollipop 5.1.1 OS again along with its prerequisites. I tried to zip-install it using TWRP but it said that "has not switched carriers and cannot be upgraded" i scratched my head and searched almighty Google again then found that i need to do ####6430### thingy before doing that. umm.. so my phone domain need to be changed, how can i do that with a phone who can't boot? (I'm from Singapore btw). What did i do wrong?? did my phone just turned into useless BRICK? but i've read that bricked phone can't even start the recovery, yet my phone still able to start either with Lollipop stock recovery or TWRP (if i adb fastboot it with adb tools from .cmd), so it's not totally fuc.. uh., BRICKED and i got the chance to fix it.

When 5.1.1 update arrived?
Okay lets get to the point. Just don't panic. You have the stock rom file, extract a file named 'system.zip'. Now go to TWRP, perform advance wipe (wipe dalvik, data, system and cache partitions) and flash that file from TWRP. You'll be on stock rom with a fresh new experience.

Custom ROMs are amazing and far better than the stock lenovo rom. Believe me, no one here is using that crap stock rom. You just need some instructions to flash and your phone will get a new life. We are here to assist you.
Hello,
I'm new on this forum and rooting is all new to me. Please don't simply delete, at least indicate where I can find my answer.
So I found a CFA that's supposed to come with SuperSU and I flashed it with Odin. The first time, I could boot, but TouchWiz constantly displaying a bug pop-up without letting me access the tablet had me flash the stock firmware back. It was unusable.
I tried again and it worked but my Tab wouldn't boot. After several attempts, I cleared partition and did a factory reset. It seems like I can only boot as in a stock firmware. I had to redo basic questions/settings as if I opened the tablet for the first time, but it doesn't seem like I have access to delete bloatware apps or anything.
1) Did I cancel my CFA flash with the factory reset?
2) I still have stock firmware and do not care about datas or anything since it's an old tablet I don't really use. Is it better to do the factory reset, then try to flash back the CFA file?
3) Did I simply miss something when I flashed and got TouchWiz bugs?
Again, please consider the fact that I'm new and I'm just trying to learn here. I can understand If I have to post this in another category, but XDA seems to be the only place where I can finally get to root, delete unnecessary apps, play with a custom ROM, etc.
