KG or RMM state Prenormal ? Know your hardware - Samsung

[lla]

Sure, there you are
I followed different suggested solutions regarding the RMM and KG Status (try to trick the phone into believing it’s been more than 7 days, the corsicanu bypass zip, etc…), it did not work. I can activate the OEM toggle with no issue but I can’t install non official FW.

[piero]

from what i have understood, you need to insert a SIM card, turn on the device, make a call and wait for a week.

not sure, but flash latest firmware could help to avoid this period

what is your country ? https://samfw.com/firmware/SM-G950F

[lla]

Thanks, My country is France

[piero]

so “XEF” Download Galaxy S8 SM-G950F (XEF) G950FXXUCDVG4 in Samfw - Samsung firmware download is latest (carrier independant) s8 french firmware

[lla]

Thanks again, I checked on the phone, a firmware more recent ending with DVG5 (instead of DVG4) is already installed, is that ok ?

[lla]

how do I flash it ? with heimdall in download mode or adb with the android recovery mode ?
I don’t have Odin (I did not find how to install it on mac), but I have heimdall, SDK platform tools, adb enabled

[piero]

Not using recovery mode, .

It is possible even complicate using Heimdall

Flashing Samsung Firmware with Heimdall
.
Flashing Samsung Firmware with Heimdall Frontend

It is easier using Odin

Finaly, i am not shure if reflashing stockOS will be usefull in your case.
as you said :

@lla

on the phone, a firmware more recent ending with DVG5 (instead of DVG4) is already installed

I looked, I am not competent enough to make it… How to install Odin on a Mac Os ?

[piero]

it is long and fastidious using Heimdall but doable with assiduity.
i am affraid Odin4Linux can’t be installed on a machine running macOS,
don’t you have a partition running Linux or Windows ?

for installing Samsung Stock OS (incuding original Samsung Firmware) my advice is generally to use Odin3 on a friend’s or a neighbor’s Windows PC…

[piero]

@piero

i am affraid Odin4Linux (CLI) can’t be installed on a machine running macOS

there are some hope for a near future with Galaxy-Flasher (GUI) :

@piero

the developper said :

Yeah, Heimdall is not user-friendly at all, sadly.
I will add support for Heimdall in a future release of Galaxy Flasher. Probably not in the next release (v0.5.2), but hopefully in v0.5.3. Then I’ll just have to make some instructions on how to run Galaxy Flasher on macOS.

for the moment you can try to use Download JOdin3 for macOS, Linux, and Windows [Odin for macOS]

Thank you,
Twice, I waited 7 days or 168h (checked in the status of phone), the RMM is still pre normal, how to do ?

[aibd]

@lla

Twice, I waited 7 days

Please can confirm that the SIM card was used to make more than 5 minutes of calls already with this phone and that the SIM was installed for the full 7 days.

[lla]

Yes I confirm , all of it

[aibd]

Is there anything in the history of the phone that could be responsible for the phone still showing RMM Prenormal ?

Please open the linked topic where a number possible issues are explored.

@aibd

KG or RMM State Prenormal

In the examples below RMM refers to remote monitoring by Samsung . So if Prenormal is triggered the device will require to be online (probablly with an activated SIM card) and (generally) in normal use, in order for the remote to be checked and for Samsung to release the device. As we see below the behaviour can be quite different depending on why the lock was applied.
…
Prenormal is a “conditional” partial lock which will allow the phone to be used as normal user, but locks the bootloader. This prevents the flashing of /e/ or a custom ROM.

Could it be (from anything you know about the phone’s history) that Region lock, Carrier lock applies or might the phone be an

@aibd

Imported device

In the case of a Samsung phone sold in a non-intended market, say a European or Asian market device somehow imported to USA, then the above Regional terms can never be met (by official means).

[lla]

Regarding the first link, I don’t see why it is still locked on prenormal
Regarding imported device, apparently this phone was made in Finland (7th and 8th digits of the IMEI are 10 which from what I read means Finland as country of origin), I live in France, it should work, no ?
It is not carrier locked, how do I check region lock ?

[aibd]

@lla

Finland as country of origin), I live in France

It is difficult for me to tell … but if originally sold out of EC it is possible that the phone is not suitable, idk if there is any sort of economic, political or other barrier.

Do you have any clues ? Did you use the phone in Finland, was it imported / sold to you recently ? Is there any possibility it was refurbished in Finland or France ?

There is Samsung support in Finland Tuoteohjeet ja tuki | Samsung Suomi if you feel like researching with DeepL Traduction – DeepL Translate : le meilleur traducteur au monde . Can you find out, perhaps, are there any Regional terms / restrictions applied to Samsung phones sold in Finland ? Seems a bit unlikely as Finland is an EC member.

[lla]

I just bought it refurbished from a French company (backmarket)…

[aibd]

You might consider returning the phone on the grounds that is does not meet your requirements / expectations. In my view a phone still showing Prenormal on the screen is not normal would be my argument to the seller.
