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.

I rooted it with this tool:

it is in chinese, but is pretty automatic.
It will flash you a recovery mod in chinese also.
Still trying to find a recovery in english at least.

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

Just flash the stock ROM for your model with ODIN. It'll take less time than waiting for somebody to post the file (unless.. a miracle happens.).

I figured however i have limited bandwith where i am now and will only be able to download the stock next weekend. want to get my phone up and running asap
Have you got an authorised PC to push the file from? I'm certain to get adb access in 4.3, you get prompted to authorise the connecting machine, a security feature, if that's the case and you haven't done it, you may not new able to rectify your phone anyway, without the full firmware?

Yes I can get recover and download mode. so I tried adb but windows not load my device. so adb pull /system/build.prop not work. is it possible do use apply update from adb or use a update.zip via external storage, if yes how do I have to make this zip?

Check to make sure if the correct driver for your device has been installed.
You can install Kies to get the driver also installed.

you should always make a copy of the rom, I have roms and firmwares at my site...
happened to me 2 days ago, I changed one hltexx to hlte or hltetmo to get my correct icons, and black screen, I just flash my good rom, keep a good copy on your sdcard or ext. so u can flash back, or restore ur backup nandroid copy.

Don't ask me how, I installed wrong Rom on my edge 7, as result, no USB connection.
So can't use Oddin to replace ROM and of course can't root.
Also, all rooting app fails, I guess because they recognize it as a different device.
A part of that the device works great, but I can't do any updates and I have a challenge...
Any ideas?

Download a suitable ROM onto the phone internal memory or onto SD card. Flash the ROM via twrp. Giving details of your phone helps too if you want tailored advice.

Nope... Didn't work because not rooted also tried original ROM.
I assume the problem Is not the Rom but the bootloader or whatever is the similar for pc operating system.
Phone is edge 7.
I'm desperate ?

Phone model number? What did you install? was it an odin flash? or a twrp flash? can it still be detected by your computer in download mode? did you enable usb debugging on your current ROM?

Hi,
Phone is Galaxy S7 Edge SM-G935F
Have no Idea what was installed...
I believe it was kernel - I attached a picture of the SFTWR details
Don't know if it was ODIN or ZIP
I can put phone in Download mode, but it is not detected - well if it was, then I could have reflash it with ODIN
And yes, USB debugging is ON
try kingroot to get root easily, then use a
twrp app to flash recovery and finally go to rwcovery, wipe everything, flash proper rom
every rom thread has an i fo about models how did you manage to flash the wrong one? if you too lazy to read you need a lot of money to repair damages ^_^

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.

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
