Samsung S20 Combination Engineering firmware used to check all hardware features like back camera, front camera, sensors, RAM memory, ROM memory. You may also run a test that shows you the results of the Galaxy S20 phone diagnostics. You should be able to use this professional firmware to bypass and remove Factory Reset Protection, Google Account verification or Google Account protection.

Cheers

Samsung Galaxy S20 Ultra SM-G9880 Combination Firmware

Below is the combination file/eng firmware(flash file) for the Samsung Galaxy S20 Ultra SM-G9880 phone.

Below are some of the servicing functions you can do with a Samsung Combination / Eng (Service)Firmware.

What do you mean by repair Knox? Restoring the Knox counter?

isn't ems a know person why would he post something thats useless?

don't know.. he is a known person as he has a RT status which you don't just get unless you contribute to XDA and apply for it and get approved.

The firmware isnt necessarily useless as it does work and is official firmware. These are the few points I have:

1. The firmware is valid factory/combination firmware and what he indicates in OP is accurate things you can do on this firmware.

2. The title is misleading as well as in OP when he calls this "engineering" firmware because it's simply not ENG firmware at all. ENG firmware you would need a ENG device to be able to use and ENG firmware is rooted by default. There are 4 types of binary/firmware. User bibary which is what comes on phones i.e. stock official firmware. Factory binary aka combination firmware which is what he has posted in this thread. ENG binary/firmware which is rooted by default but requires a ENG device or a device with ENG mode enabled which requires a ENG token. EanG firmware is hard to find these days and is mostly useless without ability to flash it. Userdebug binary/firmware which also requires a dev device or token to allow userdebug firmware which is also rooted by default and even more difficult to use/find than ENG stuff is.

3. The factory/combo that is posted in OP can only be used if you have a factory binary token or some sort of exploit to bypass need for a token so most everyone that is on XDA can't use the combo/factory firmware listed. When you try to flash it, it will prompt you that you need approval to use factory binary (aka token) even if your BL is unlocked.

Hope that clears up your question and for anyone else that reads here.

    Dear Scott,


    - we talking about Samsung firmware or about Qualcomm firmware?
    - what part of firmware most important for root or we need just complete firmware?

    please more details

    thanks

    Exynos models are typically able to be bl unlocked

    Snapdragon chinese or latin america devices are typically able to be bl unlocked

    Snapdragon usa models aka U U1 W or carrier specific models are not able to be bl unlocked and need exploits to root which has become difficult since s9 models (although i released extreme syndicate root for usa variants of s9 s9+ and n9)

    I tried various things on g975u and n976v with no luck in rooting even on combo firmware or edl.. I only managed to elevate to system privs..

    Is it impossible, no. is it difficult, yes. Until exploits can be found then it will not be rooted.

    If anyone doesnt know, I have been researching samsung security for a few years now. I was worlds first rooted S8/S8+ as well as worlds first rooting s9 s9+ n9 all usa variants and various exploits I found during my research.

    All exploits have been patched with each device release i.e. 8 devices exploits dont work (to an extent) on 9 devices and 9 exploits didnt work on 10 devices so i cant imagine any of my 9 exploits working on 20 devices.
