[Q] Firmware not installing on S5570

I have flashed multiple roms on the phone, still the same error, could you please suggest further steps?
The phone had been sent to get the simlock removed, once I got back I performed a wipe to remove all personal data. since that time it's not booting at all.
I can turn into download mode and flash anything, but cannot enter to recovery, I got the notification "ramdump mode (arm9 mode)"
Thx in advance for any help.

If you flashed a stock firmware successfully it will not boot into twrp, flashing a stock firmware will install stock recovery, which means the stock firmware did not flash properly. Have you tried smart switch at all? Are you sure you have the correct firmware to flash through odin?

Yes I am sorry I didn't explained that. Atfer I tried to install stock ROM it got stuck, then smart switch didn't recognize the device but I manage to do the emergency recovery thing with model number and s/n but same thing it got stuck on the same installing system update screen. After that I installed TWRP via Odin to try to push a custom ROM zip, I did that but when I tried to install it failed.

Download Samsung SmartSwitch and from the upper menu select Emergency Recovery Mode, put your phone in Download Mode and connect it to your computer, enter your model number and S/N when asked, and it will download and install latest firmware for your model.
Sorry, i haven't seen that you already tried that.

That means TWRP works and Fastboot/Download works. What is the actual Galaxy S6 model? Mine is G920F.
What custom ROM did you try?
What version of TWRP are you using? The wrong one can create issues.
Did you wipe the phone trough TWRP first? Twice? Including internal memory?

Galaxy S6 probably softbricked? Ran out of things to try,

I've tried everything that i could find using google. Nothing has worked so far.
My friend has a S6 that was on 5.1.1 with root. It didnt received OTA updates so he tried to flash the new Nougat rom using ODIN. Alas the phone softbricked.
I can access download mode, but doesn't matter what firmware i try ODIN always end up failing. It's either sboot.bin, cm.bin so i think it has something to do with the bootloader? I'm not sure.
Tried to use SmartSwitch too but after it downloads the firmware it gives me an error and says to enter safe mode (????) so that's not working either.
Has anyone have an ideia of what to try next?
Thanks in advance.

Hold down all the buttens on the phone , it should eventually get to download mode , then flash twrp and then flash a rom and see if it boots that way

Already tried. Touchscreen on TWRP is not responsive.
Do you using latest Odin 3.12.7 and newest Samsung USB Drivers and latest right firmware for your model (the best way to get it is SamFirm)?
Softbricked S6, Only Download mode
Hi,
I'm facing the same issue. Tried multiple firmware from sammobile using latest version of odin. I can access only download mode and when not in download it boots till the samsung logo and goes into bootloop. https://imgur.com/a/9bJnM

Touchscreen is not working on TWRP. I'm downloading a Custom ROM and will try to install it trough ADB using TWRP commands. Shot in the dark.
Ended up not working.
Tried PhilZ recovery and I got to flash Global Elite rom but it doesn't boot. Is PhilZ compatible with Nougat roms? What else can I try with this recovery.

I flashed TWRP using odin and got "pass" message. But i cannot access recovering mode. I can access only recovery mode and after flashing with stock rom i get the message as "pass" in odin as always but same bootloop.

Download right newest firmware for your model, use SamFirm to get it. Then use Odin 3.12.7 with newest Samsung USB Drivers to full-flash stock ROM. Set also "Factory Reset" in Odin then START. If Odin shows you 'pass' then everything comes good.

Did you for sure used right firmware correctly for your model etc? Look HERE, try like that.
How is/was your reactivation lock? On or off. I had problems with odin when it was ON.

It is OFF. See here => https://imgur.com/a/9bJnM I downloaded the right firmware for model. I'm sure of it now. Used samsung smartswitch to know my csc code using serial number. Still i'm facing the same issue. I'll try flashing it on another pc later today. Also, Should i change any odin setting while flashing ?? Like NAND erase or bootloader update etc

Not necessary, just "Factory Reset" and that's it. I don't know why Odin shows you "pass
" and your phone still shows "system status: custom". Looks like Odin didn't flashing correctly.

This was before i flashed using Odin. I tried flashing twrp first and then stock rom. Does this make any difference ?
P.S: I'm not able to access recovery mode, only ODIN is possible.

Ok, but why stock? If you flashed TWRP then full-wipe and clean install for example Noble ROM. Try like that...
