Is A20s not A20x? - Samsung Galaxy A20 Questions & Answers

It seems like the SM-A207/M is not an A20x and ought to be called A25. Especially since the A20 is 205, not 207.
Anyway, what can you do with an unlocked bootloader that won't root and has no TWRP?
You can enjoy a pointless warning at boot.

Root LG V20 918-10r

How to Root LG V20 918-10r?
There is no root available right now for 10R or custom recovery due to the security patches that have been rolled out. Since H91810j anything after 10j is ARB firmware ( anti roll back ) so no downgrading to anything lower than H91810p . I'm sure there's ppl working on it ( root ) and recovery. Designing root and recovery for each individual security patch is a lot of work and trying to force a rollback exploits is high risk due to Q fuse blowing and forever bricking the phone or send it back to LG ( long wait times ) . I think the best route to getting this device to full root and recovery is by downgrading it's firmware and finding a loop hole for ARB so H91810j can be rolled back and once that's achieved we will be golden. I was on 10r i rolled back to 10p and sit here waiting for the ball to drop.
I have an unlocked bootloader but have 10r on my phone.... Unlocked bootloader sitting there being all useless and lonely with no friends like twrp recovery no root no xposed to play with.... My poor Poor bootloader
Haha, same here and in the past it's normally the BL that was the problem to unlock. The biggest thing we need is just to get these phones to roll back and disarm ARB. I feel bad i can't contribute to the cause or i would and to get the justification of saying T-mobile & LG nice try but your ARB can beat it. Out of all the things to worry about and lock down is to choose what version of 7.0 Nougat your on and it's the same version it shipped with, lol spending more time with security than actual OS updates.
So, H918, never touched with 10r, I'm SOL?
The phone lags something crazy, particularly running Android auto (means connected via USB and charging) and trying to dictate things, using Nav, playing podcasts. Rebooting doesn't help. Sent in one phone, got another one with the same problem. So, the phone is useless? Just don't try to do anything heavy with it, is that where it is?

I have an s8 that I have always used with android 8, magisk and rmm state.
When version 9 came out I tried the same procedure and it worked very well, I installed twrp, etc, after updating all Google app and reboot it presents the message "only official realease binaries are allowed to be flashed" and in download mode it accuses KG Prenormal.
In summary is there a way to have root on the S8 with Android 9?
Well I read almost every post back and I could not reach a consensus.
Someone?
up.

Yes you still can. I had RMM state prenormal and kg state prenotmal when ii flashed pie on my S8.
For me to be able to install twrp,root and xposed I had to get the
Kgstate = checking
Rmm state = normal ( in my case disappeared from download mode )
While I didn't use the method provided in the link below but due to work commitments over the last few weeks I haven't had time to re-try the method I used as I like to test a few times first as it may have been a fluke. I have an S9 with the same.issue to try on. The process took me about 15 - 20 minutes to do after a lot of trail and error.
Currently for my region the latest security patch is feb. which is the version I used to root the phone.
The issue with the new kgstate is still being looked at. The link below has more info and a another possible short term work around.

I just got it to work. I'm just testing the procedure again to make sure and put it here.
I arranged this item like this.
In Android 9, installing TWRP soon after installing Android no longer works, after installing TWRP, it appears in red "only official realease binaries are allowed to be flashed" and restarting in the download mode appears KG STATE PRENORMAL.
To fix I installed Android 9 again without the TWRP, Magisk, etc, that is, pure. I entered the system and started the updates by Google, when I came back to check in download mode KG STATE was with CHECKING which is normal.
With this I returned everything to normal, I installed TWRP, Magisk, etc. and I continued.

Do you mind sharing how you did it?
I had my bootloader unlocked and flashed TWRP successfully while on Android 9.0. My phone had a fit so I flashed stock firmware. Turns out my it was actually my mobile provider who had issues, not my phone. Also had to do a factory reset to get back my full 64 GB storage. Somewhere along the line my RMM_State tripped to prenormal. I think KG_State did too. I was fine to wait 7 days, which I did (over 8 days uptime). RMM_state is still prenormal. KG_State does not appear.
I'm wondering if it has anything to do with the fact that my original firmware was region XSA, and I've ended up on VAU (because I'm with Vodafone, though I bought the phone outright from the shops). So my firmware region is XSA, while my Carrier_ID (in download mode) shows up as XSA. Do these regions have to match?
I'd appreciate any advice on removing the prenormal state, even if it involves waiting. Maybe involving flashing an older bootloader? I've done a tonne of searching, and I'm finding it hard to find information that is relevant or likely to work on Pie. Cheers.

is root worth it on S10?

I recently got a contracted Exynos S10 and have been reading some of the horror stories here after failed root etc
How stable is the S10 after root/unlocking bootloader? magisk is pretty cool , aye
Should I root it?..
Horror stories come from people whom don't do research and follow instructions slowly and carefully, and not confident.
And make it out as its the actual root that's the issue, not them.
I got my s10 plus just 4 weeks ago, i read up for few days, watched videos, understood how root is different slightly to past models.
I found this video which is excellent to help understand about unlocking bootloader and rooting.
https://www.youtube.com/watch?v=o3a8YnWT3yk
Thou i used only how to unlock bootloader from this video, after i downgraded back to pie from ten, then installed a stock with twrp and magisk already patched with superb help from the member, Comsite:-https://forum.xda-developers.com/s10-plus/how-to/root-unsuccessful-everytime-t4042427
Then if you want to get rid of ugly bootloder warnings splash screens, go here:- https://forum.xda-developers.com/galaxy-s10/development/g97xf-soldier9312s-splash-screen-t3929748
Yes rooting is different, but take your time and go for it, so many benefits from rooting for personal reasons :good:
It depends. If you are fine using the phone without Samsung Pay and OTA. Is worth it.

But is it stable. I find the S10 unusable when Ive got too many background apps running or do something else it doesn't like. Nearly every phone Ive owned has been rooted so I know abit about it.
Ok so I wanna root my S10 ,but when I reboot to download mode (OEM unlock checked) I hold volume up but I don't get a prompt to unlock bootloader, also, i can't enter recovery or download manually , bixby + vol down/up & power. Any ideas??
Success!
I tried to install official twrp in the thread. Big mistake. Nearly killed my S10
It wasn't untill I flashed stock including stock ap file from Odin that I could flash magisk, kept saying only official firmware can be flashed to this device or somethin... :silly:
In my personal opinion,
- 5 to 10 years back, rooting has lots of more benefits
- currently, there are many alternative solutions to rooting for ad blocking, freeze apps etc.
I did not root my phones after S8 and now s10+.

I did not regret rooting my S10 on pie. Themes, magisk modules like viper4android.. it's awesome
I rooted my S10+ Snapdragon (as I have my last 5 phones) first and foremost for Gravitybox and 'Hold back to kill'. After that it was for Afwall+, Edxposed/Magisk, Xprivacy, AppOpps, Greenify, Button Mapper, Icebox, Isolated app storage, and the excellent Maxlock. Samsung warns rooting makes your phone less secure, which is true if u lose it. Password can be bypassed and won't be encrypted, ADB vulnerable etc... So don't root, just let Samsung(among others) run network connections in the background for almost every function you choose
I feel much more secure not being data mined constantly.

I updated to 10 with magisk 20.3 and it's much better than pie. Awesome
Edit: downloaded with frija this is the ops stock rom I used. 1/3/20 sec patch. Includes already magisk patched ap file :good:

Changed an SM-G935P to SM-G935U but cannot root

Hello. I am a Noob when it comes to rooting, but I've unlocked over 600 androids and 10 iPhones, so I "ain't no dummy"...lol.. My problem is this... I took an SM-G935P w/ unlocked bootloader and flashed G935U (bootloader 11 ) 8.0 firmware to it. Now i can use it on whatever network, which is cool, but even though in Developer Options it has the OEM Unlock toggle turned on, I cant seem to be able to root the damn thing.. TWRP keeps failing ( Recovery), CF Auto Root fails (Recovery)...Even the One Click Root crap fails.. I've seen several Oreo root files, but they are all for binaries well below mine...
I need some help here. Did I possibly lock the bootloader when I flashed the firmware to U? What can i do now to acheive root?

How did you manage to flash G935U bootloader to G935P, hence unlocked carriers. mine is also G935P

CANT ROOT!!!!! tab A 8" 2019

I have tried every piece of software and read every forum on the internet and this thing will not root!!!
Kingroot, kingoroot, magisk, framaroot, superSU,
All give me an error saying they are designed for an older system and then crash.
Is it possible that this tablet cannot be rooted? Or that I need to wait for software to be developed or something?
Easily over 20 hours of reading, reformatting, plugging and unplugging and I have tried everything 5 times now.
HEEEEEELLLLLLLLPPPPPPP!!!!!!
bump.
every time i get al the way to the end of the tutorials the tablet says
SECURE CHECK FAIL VBMETA
SECURITY ERROR THIS PHONE HAS BEEN FLASHED WITH UNAUTHORIZED......
Are you flashing the multidisabler ? https://forum.xda-developers.com/t/...of-stock-recovery-proca-wsm-cass-etc.3919714/
And everything you listed there is old and probably will not work on 2019 version.
