Welcome to our forum. No doubt you have already found this resource: https://forum.fairphone.com/t/purchase-disclaimer/47160
You donāt say whether intended FP2 has any remaining Fairphone warranty left or not; if so you need to know sellerās original Fairphone order number and ask him/her to inform Fairphone support https://support.fairphone.com/hc/en-us that you are the new owner. Be aware for example in UK where FP2 sourced from Phone Co-op not Fairphone themselves original Phone Co-op receipt required for warranty work.
Slightly confused by need to register FP2, is this with Fairphone or authorities to tie SIM to IMEI? I do wonder about insurance as quite often mobile repair companies used by insurer have no knowledge of Fairphone devices and usually write off as repair not viable.
I would try to ensure that your purchase is one of the later models (left picture of two in link by paulakreuzer) as SIM pins in holder much more robust.https://forum.fairphone.com/t/fp2-microsim-adapter-broke-sim-card-slot-pin/12225
Make sure that you get a picture of the phone showing the date on the screen.
Not the date of months ago, but the date of today or yesterday.
It is easy to check if an imei number is a number of a Fairphone. Search for āimei number checkā in your browser.
And sadly, I have to warn you that we have seen fraudulent attempts, even at this forum.
Hello @aspergerguy and @Lidwien thanks a lot for those answers.
the seller gave me many informations:
IMEI 1 / IMEI 2 / SKU / Made On date / Assembly date / Assembly Number / Serial Numbers.
and she told me that āthe primary microphone must be dismantled and reassembled according to the diagnose of Fairphone technical serviceā.
I did some search on the web about IMEI but founds nothing;
should i post all those informations here ?
Please forward this information to me personally.
Click on my name and then on message.
okay iāll do it now thank you very much 
Hello again; i did more researches on the web and i found those IMEI checker:
those 3 webside said āthis FP2 is cleanā; should i trust em ? are those website usefull ?
I hope that you have deducted cost of possible replacement module and shipping cost from Fairphone from sellerās price, should dismantling and re-assembly not be sufficient.
hey
thank you for this advise, yeah i thinked about all of that;
the price she want for this FP2 is really cheap (45ā¬);
she said she used it from many years only with Android without touching anythin, and now she buyed an FP3;
i may have to change: the primary microphone/bottom module;
then buy a slim case and probably buy a second battery for more autonomy.
i regulary āplayā with Flash zero of informatics objects, and i āassembleā computers for fun since many years ago, thatās another reason about why i choose Fairphone,
i like so much to do those things by myself; if i can i wish i could work on informatics or electronics job 
At that price probably worth it for a āworking screenā. Hope you enjoy your FP2 with the advantage of a wide choice of operating systems available:
Fairphone OS
Fairphone Open OS
Lineage OS (With or without Google services)
Sailfish OS
Ubuntu Touch (with or without Anbox)
/e/ OS
Did she already showed you a photo of the phone with the display showing the date?
hi, not yet (i answered you in private).
haha youāre accurate thank you, i was just searching āOpenOS vs UBportā on the web these days, and i just found that LineageOS =D
i am trying to get out the GAFAM, because they too evil (and i am about to achieve my goal ^^)
First: iām not on any āsocial-mediaā since years; i was here before them, still alive without emā and IRC+Forums is enough
(and i lovely remember that old good times when trolls where not allowed to disturb everything for free)
Then i use Protonmail (instead of Gmail), Telegram (for communicate privately and safely), Brave navigator (no dirty ads anymore), PreSearch (accurate as g00gle but really private).
i am also making my own invasive addās filter with PiHole (on my Raspberry Pi).
the last two of āthemā i aināt found any replacement for are Y0utube for videos and Micro$oft Windows10 for gaming.
I use K9-mail , Signal, Fennic and Osmand
wah, i know Kmail, but not K9-mail; and never eared about them; are they in your country based ? Open-Source ? iām curious haha
(i think you are a Linux user am i right ? wich distro do you use ?)
i will notice these names and do some research about it;
because the more non-GAFAM solution i know, the more safe i can be =D
Sorry, itās K-9 Mail. I downloaded it from F-Droid.
I always start looking for an app on F-Droid first.
Yes, I am on Linux. Fedora 30. Need to upgrade to 31 at least. At home I prefer a desktop, itās better for my working posture.
Only on holiday I use a laptop. Itās on Xubuntu now. I had a problem with the wifi on Fedora.
Did you ever hear from Boinc?
BOINC is an open-source software platform for computing using volunteered resources.
I am running for World Wide Grid, mostly on OpenPandemics - COVID-19.
There is NewPipe or SkyTube from F-Droid to watch YouTube videos directly from phone. Quite handy.
For eMail I also suggest FairEmail which offers encryption with PGP and S-MIME (check out e-mail certificates from CAcert, in case) or pEp based on K-9 mail with similar capabilities.
Like @Lidwien I also suggest to search on F-Droid first.
For OS, I personally like LineageOS (just plain, without Google framework, but I understand itās sometimes difficult), or /e/ OS which is a fork of LineageOS with - as they claim - many deactivated Google calls but they include microG to replace the Google framework with open source rewritten code. According to e.foundation itās made for an easy-to-use OS without using Google.
nice, i should keep an eye on BOINC.
for myself i work with Debian for my server and my projects; i also use Windows10 on my main computer because of gaming ^^
@Amber hi, F-Droid looks usefull, maybe i should use it when i have my FP2-with-non-g00gle-OS-installed. 
btw i should stop with full of many questions in this topic,
i have to search a bit by myself , because i want to compare all of those FP2 Systems.
i will create another topic in a more-accurate section of the forum
oookay, i just receive an answer from the team;
they said my FP2 does not appears stolen \o/
now i can focus on buy part for my FP2 and some other things;
thanks yāall for all answers, see you soon
