That's strange. I have tried the code on two AT&T models and nothing happens. Which model do you have and can you explain what you did step by step to get it to work. I just entered it in the phone's dial pad and nothing happens.

It works for me, international version.
Also just put it as shown into the dial pad.
Though you should be abe to see some of the diagnostic tools if you go through the HTC Guide App, IF you have it in your app drawer? Doesn't give ALL of the possible diagnostics but it gives a couple of it.

International version. Just copied and pasted into the dialler. Have you tried enabling the developer options see if that helps?

Yep, developer's options are on. AT&T most likely removed the function or changed the code

Why the sim unlock code t-mobie sent me is not working, please suggest?

I bought a t-mobile dash with WM5 from ebay, I sent the request for sim unlock to t-mobile, and I also received the sim unlock code soon. but the unlock code is not working in my dash, when input the code two times, the below message appeared :
you have tired 2 times please wait for retry.
but I know if I try much many times, the phone will be permanently locked, so I did not try again. I also send email to t-mobile, but no feedback so far.
appreciate anyone suggest me. thanks
have nice day to all
make sure when you provide the IMEI is correctly spell, and also whether your phone IMEI (*#06#) and the back of your phone IMEI is the same, and that number is the number that you give to them. I got mine unlock with t-mobile too, my phone IMEI is two number extra more than the one i found from the back but they will figure it out and send me the correct unlocked code.
If the IMEI you provided is correct, then the previous owner nuked the configuration data or entered too many times a wrong code. I would be able to verify and correct that. Drop me a PM and I will make you a reasonable offer.

thanks for your idea
same as your situation, my phone IMEI is also two number extra more than the one on the phone back, but I send the t-mobile the phone IEMI(*#06#), not shorter one, if the unlock code is correct, i do not know why it is not working. what should i do next?

The code you will get from them will be the same as the one u got from T-Mobile and also the same as I would find for you: there is only one unlock code. However, your problem is that either the simlock data area is corrupted or the prev owner tried to enter unlockcodes too many times. Ah well, tried to explain that already ...

McAfee pin after factory reset

Could anybody assist please. I have bought a G3 from somebody on ebay and when I start it up, the device is asking for a MacAfee pin. Without this pin, download and factory reset are both disabled. I have not been able to get in touch with the seller yet however, from what I have been reading, after a factory reset, this will happen even if the user hasn't even opened the MacAfee app previously.
Could anybody help with this or have any experience with similar? :crying:

Can you post a screenshot of the mcafee screen? Also have you tried powering the phone off holding vol down and power to get into the boot menu and trying a reset from there?
You may have to press vol up on the screen to get into the boot menu.

I can't post a screen shot as my device isn't functional and I don't have a camera however my screen is pretty much this one http://forum.xda-developers.com/showpost.php?p=53722932&postcount=1 without the 'wrong pin too many times' warning.
I tried the reset option that you mentioned but this is disabled by the security as is download mode. :crying:

No, it's a uk model. The seller has got back to me. The code was 123456 (obviously )
It's a 3UK version. I assume I can flash the generic uk kdz? I'm on EE.

Not sure too be honest and I would stick with the 3UK firmware as this seems to support all LTE bands and the generic EU version seems to have an issue with certain 4G bands from what I have read here.

what was said above ^
but back to your question. Yes there is a diag mode available, but you need a bypass card in order to access it. this diag mode is normally meant for diagnosing faulty mainboards, and the such.
so basically yes there is a mode, but no your not going to be able to get access to it. cause the card itself is a unicorn, and there have been some home made cards but realistically if your trying to download / change the bands its nearly impossible. since the firmware's are so locked down.

it's avaliable on sprint m8 with this code ##3424# , so what's problem with t-mob m8?
i think there should be some adb commands at least, but i'm asking if there is some code for it , like it's on sprint version
It should be the same code for all devices, unless the carrier has disabled it

service mode

Hi,
I cannot access to service mode menu *#2263# , blank screen, I have exynos versio of note 10.
Any idea?
Works fine on my US SD model.
My unlocked 10+ flashed with t-mobile firmware works for that service mode.
BTW did you try other codes like *#0*#, to see if they work? I also remember something about Exynos having different sequence for some codes than SD in the past, but I don't remember details. I think there are some apps that can list all the codes available for your phone, so that would be my next step.

dl phoneinfo.apk or similar that lists all the dialer codes for u to try..
if none work then its possible ur carrier disabled them.. if u have root u can enable them.. on sd devices you would enable in the file /efs/FactoryApp/keystr and /efs/carrier/HiddenMenu..
i have vzw who blocks dialer codes so i always have to enable them manually..

But we can't enable on vzw on note 10 cause no root correct or did I misinterpret?

eSim/BL/root

Just a real quick question before i return the phone tomorrow.
On the g981u1 (purchased from google through Fi), same as everywhere else, has the sim manager disabled, bootloader not unlockable.
From all the searching i did today, which was horrible, i just wanted to verify in a last ditch effort before sending it back.
The only way i found to enable esim is to modify the features.xml (from sounds of it). However to do so you need root, and of course it appears root requires unlocked bootloader(unless i missed something somewhere)
I have been unable to find a way to unlock bootloader(am i wrong?)
I havent found root (without unlocked bootloader)
Edit- nvm i found what i was looking for

So far, no go on the esim. I did get unlocked etc, but it seems something else is keeping the esim inactive. I almost need a snapdragon with esim working (from another country) to compare to

Snapdragon variants aren't eSIM enabled, only Exynos devices.
I remember seeing the option enabled when you flash the Exynos magisk module on a Snapdragon device. It also gave me call recorder.

CSC change does not appear to work on snapdragon, i already tried it.
HOWEVER, editing Build.prop in vendor did enable sim manager for me, however status is showing esim imei as unknown (yes my box has 2 imei) and the add gets stuck

I am rooted/unlocked
In vendor\build.prop i found "persist.radio.multisim.config=ss" which is single sim. dsds would be for dual sim. Phone would not let me modify or replace the build.prop.
With the recommendation from Orphee i installed this package in my magisk
https://forum.xda-developers.com/apps/magisk/module-magiskhide-props-config-t3789228
From there it let me change that line to dsds, and thus here we are. I am unsure if dsds should be a different line for esim, or if something else is needed to "start" the esim.
Are both modules enabled ? CSC and Props config
And is there 2 IMEI written in phone About screen ? Not only the box.

Currently the IMEI for esim shows unknown, so it IS possible i broke that during UL/root or something, but i feel more inclined to believe it is just not enabled. On stock rom it only showed the normal IMEI
I have tried both yes
Then you must fix or find how to have the IMEI number shown in the phone menu.
Esim registration will not work until you have the IMEI number shown.

Download Google dialer and then enter *#*#467#*#" and there's some esim related toggles available now.
You can enable RCS here too if you know what you're doing.
