I was asking in xda because I can't find any tutorial for fixing unknown baseband for this device.
No tutorial for reverting to stock after on LineageOS.
No tutorial for downgrading from Android 7 to 6.
There's tutorial to use IDT but it requires opening the device and shorting test pins

If You think can find solution only 1 place continue find by Yourself, I only notice for You if the tablet still can access Fastboot/Upgrade mode dont need open mainboard, and You still want open it use method testpoint good luck for You

reboot in to recovery, power off the phone, and power on, pressing volume down, until it enters recovery mode.

It worked, thx. But now, I had a bigger problem. After I rooted the phone, it cant connect to the mobile network, I even can´t make a phone call. I write - No service. I tried 3 sim cards including my own, which worked in this phone before the root :-/ I cant install gapps, becose it write, that it cant verify the signature. Can this be undone somehow? Because now the phone is useless

I'd like to, but i don't know, where to find it and how to do it. Could it be done from some back up, that you can create from your phone?

Well, if you installed this ROM then you should be able to root by this method and then you can install custom recovery.
that method for me as like asking me to make new window 11
the Q, why if i try to install any SD update it say signature failed?

If you have to ask this question. Then you should of never rooted you phone. These are Basic things you should be able to do. Before you root.

You need to download Odin, then download one of the recent firmwares like PD8 etc. Put your phone in download mode, hook it to your computer, open Odin, click AP then pick the firmware file you downloaded and hit start.
You should have Odin from when you rooted and you can find the firmware file on the forum here. Just search for PD8 or PG1.
You soft bricked your device. no big deal Samsung makes it fairly easy to fix. Download Smart Switch to your computer and use the Emergency Software Recovery/ initialization process to recover your device. You will have to re initialize your device and you will lose everything on your internal storage but your phone will be fine.
Again the root method discovered uses an ENG boot and is not meant for every day use it is not true root and will always cause more issues than it is worth.

Stuck on Android 4.4 CUCC

Hi Folks,
my situation is the following, I'm stuck on Android 4.4 CUCC. My cellphone wont get recognized by the PC, I think it is something related to the SIM Card reader according to a post in another website.
So, i would like to downgrade to Android 4.3 but I cant get root access and I cant change recovery or whatsoever.
I was thinking, maybe, from recovery install directly the old firmware but with the current recovery.
I dont want to brick the cellphone or something.
What do you think? Would that work? Any other suggestion?
Or a way to get root access or install at least the play store?
Thank you in advance
Why you can't change recovery?

Thats why i am asking if there is another way, or maybe trying to install from the droidboot mode the 4.3 firmware. But i am afraid I will brick the phone and since i am not able to connect it to the pc, i wont be able to save it

There's no flashable zip for 4.3, so, the only thing you can do is flash custom-stock based Lollipop ROMs, or another custom ROM.

first of all, i need your firmware, your root method you tried. If you bootloop your phone you must flash the stock firmware through odin .. and then root with a legit way.

i am little bit confused, help me to help you ! Well , now your phone is bootlooped or no? If it is not , what rom do you have? stock one ?
You can try this method as well, because the method you tried needs to flash a custom rom . i do not like that kind of root method . For me first you flash twrp through odin, flash root, better magisk, and then flash your rom .

alright you are gonna need to flash stock rom from sammobile look the link bellow, but first create an account on sammobile . the process will take like 3 hours . after that you flash the stock rom, and boot your phone normally, enable dev option by tapping 7 times on build number on software information, then go to developer options and enable Usb debugging, get your phone on download mode by turning off your phone and pressing the power button, bixby button, and volume up to flash root . i think you know the process . i will be waiting for you reply.
search for your country and csc first. unless if you already have the firmware on you pc.
