Any chance to get Root for the SM-G8870? - Samsung Galaxy A8s Questions & Answers

Hey @All...
i get this device short time ago and think it is a very good basic smartphone.
Is there any chance to get a recovery and root? If doesn't thats waste of a good phone... and i must sell it
Best greets and wishes for 2021 !!!

Update...
Unlock Bootloader, in dev options now constant ON. This option now always displayed, also after flash stock firmware and factory reset! USB debugging is also on.
RMM state is checking
FRP lock is OFF
OEM lock is OFF
Think problem is Qualcomm secure boot stay always enabled!
Secure download always stay enabled!
I tried the method to patch the stock AP or boot.img via magisk and flash with odin to get root access. Only patching boot.img after extract them failed in magisk at repacking...
Patching the whole AP file works great!
After flashing OEM BL, CP and CSC with my patched magisk-AP.tar Odin shows passed and all succeded.
When i boot back to stock recovery, factory reset and try to boot the patched system it went till the boot warning with the kernel warning and reboot automaticly. At this point the phone gets a infinity boot everytime till this warning...
I tried this method to boot into the patched system...
"Press and Hold Volume Up + Power buttons, release all the keys once the Bootloader warning appears. You have to set up your device like a new device."
Every help is welcome to get a rooted Galaxy G8870!
Best greets from germany

Last update on my side!
Seems we can flash magisk patched boot.img/AP file. But no way to boot the device into the patched system. I think qualcomm secure boot block this...
If there's a way to bypass the secure boot we can get root, if not theres no way!

This is how I unlocked the factory reset protection on verizons galaxy mission
If you want to unlock the factory reset protection there's no way to do it through the old-fashioned going into developer mode on this phone particularly you have to basically erase all your accounts off of it Google and your Samsung account and your little message will a pop up saying that you are factory reset protection is not enabled do you want to do this blah blah blah and then there it is unlocked once you reset it it won't be there when you redo your phone so this is the way to have your factory reset protection off when you go to root it...... and thank you very much..... ps... it's right there in the instruction booklet of the phone when you buy it guys come on
Thanks...I was unaware of the instruction booklet for I Em A Reel Old Gee and got mine off the meen streets of Mayne. Thanks A Gain

[Guide] How to Bypass the RMM Lock widthout waiting 168hrs

1. flash the exact rom that you have (stock) with odin deleting all and UNCHECK "Auto Reboot" in options tab
2. restart ODIN and the phone DIRECTLY to DOWNLOAD MODE (don't boot to recovery or rom)
3. flash a custom recovery
4. enjoy
(in case that the phone starts rom after flash, retry from step 1)
It works on my A7 2017, and a guy with an A5 2017 works too7
*I'm not responsible for 0x1 knox, incorrect recoverys or whatever you do with it, this is just a way to skip the 7 day wait.
Good Luck
Excellent! This is yours experiment?
Can someone confirm that it works ?
You can't flash custom recovery when RMM is locked
???
is too strange, that works some times, if don work try with other country rom or another android vercion, just be sure to don install the July pach that blocks Nougat bootloader (you can't install Nougat again or custom roms)
Hi experts,
I am using A520F/DS. When I bought the phone one year ago, the boot loader is U2, the Android version is Marshmallow (6.0). After updating through OTA to Nougat (7.0), I found that boot loader is U4, baseband version is A520FXXU4BRC1, build number is NRD90M.A520FXXU4BRC4. My questions are:
1. May I wait 168h without touching the phone to flash TWPR successfully?
2. After waiting 168h, how can I boot into ODIN mode? Switch off the phone normally then boot into ODIN mode or boot directly into ODIN mode while the phone is on.
I know to boot into ODIN mode by press Power+Vol Down+Home at the same time.
Thanks in advanced

After waiting for 168H, just turn off the phone and switch on download mode (Vol -, Home and Power). Uncheck the option "auto reboot" in odin, flash twrp, then just force the twrp before starting the system and flashing the rmm zip.
It is now 2022, so is this procedure still relevant? Also is it OK to go from phone on to download mode by using the command adb reboot bootloader ?

'fraid not. I have a A7 2018 and can only flash firmware with Bit/SW REV. 5 using Odin. Any other firmware, TWRP etc, fails.
Does anyone know how to overcome this?
But yes you can go direct to download mode using adb reboot bootloader.

Huawei Mate 10 Reboot Loop - No recovery - Fastboot only

Hi All,
I am currently in the phone repair business. Well i buy as much as i can fix and sell on. Its all fun. I have a very nice one currently and looking to see if anyone has ideas. All i want to do is boot to recovery that is my current goal.
So phone clearly has corrupt installation, likely a flash Rom or update gone wrong. It boots to Huawei logo then reboots and that's all it does. Tried de-powering and all sorts including removing battery cable but to no luck.
There is no recovery mode
No download mode
Can get to fastboot but unable to run commands it seems due to FRP lock. I am not worried about FRP lock at this time, i only want recovery back.
Tried:-
All flash commands and all fail
Any attempt to get to receovery or download mode fails
All three buttons to force SD card boot fails
Currently trying to boot using SD card but seems i need to change boot devices from within recovery. Well it has no recovery mode so no luck there.
So it is pretty much a brick at this point and could be a write off but before I give up does anyone have any other ideas? maybe a FB command i can run with FRP lock and bootloader lock on?
Thanks
Karl

Cannot power off

I installed stock Android 10 Q (from 9 P) via Odin on my galaxy tab s6 LTE, then i unlocked the bootloader and rooted with magisk (manager 7.5.1, zip 20.4) following the magisk git site installation instructions (which are a bit more complicated than from some third party sites.)
Everything ok, but then when i power off it reboots. It's not in a bootloop: it boots up normally, but if i can't power off then that's not good when I'm not using it. I tried patching again and checked i got the the same md5.
Eventually i found that if i booted to recovery mode and there i choose reboot, it reboots to unrooted, but it does power off.
To get root access again i start with the recovery key combination but let go at the splash screen before it enters stock recovery mode. This means that i have to reboot each time i want to either switch it off or have root (but not both.) It's good enough for now, so I'm posting this in case anything else has the same problem.

Anyway to recover my S7 Wifi?

Edit: I used Odin to flash back all the stock firmware and I can now get back in the tablet. Any idea what I did wrong with Samsung Multi Disabler?
Was trying to flash my tablet and was mostly done but after trying to flash the Samsung multi-disabler the tablet will no longer boot. The Samsung and Knox logos come up with the Red Text warning about the root but the screen then goes to black and the device reboots. I am able to get in to download mode but I am unable to get into Recovery Mode as the button combo will not work.
1: I unlocked Boot Loader
2: Rooted with Magisk
3: Disabled VBMeta
4: Disabled Android Safeboot
5: Flashed the TWRP for Android 11
Everything booted just fine at this point so I flashed the Samsung Multi Disabler using the "TWRP Manager" from within Android. Now my device is stuck a boot loop and I cant get out.
Any help is appreciated.
