eSIM?

[VICosPhi]

the lady on phone said i didnt have to, this is my first claim so idk ... i guess ill see monday when i get it,

She probably was misinformed. You have to return your defective device within 14 days or something once you receive the new one.

Gotcha. Thanks. I was going sell it. Guess better wait then

Be pretty nice if they just gave you a $1200 phone for only $99 and nothing else. I'd be making claims all the time and selling them to make some money lol.

Weird. Never seen that screen before. Idk but I flashed Verizon firmware on my xaa to try and get certain features, also flashed back to unlocked firmware with no problem. I'm also not rooted tho, so idk.

Changing CSC to Verizon doesn't provide you all features? Do you really need to flash firmware? Just curious. What additional features does one get by flashing firmware that you wouldn't get by changing CSC?
Or Is it because u had XAA firmware?
FYI i have unlocked Tmobile branded Note20U and then when i moved to ATT, i changed CSC to ATT and get all features, no need to flash ATT firmware unless im missing features im not aware of.

RCS does not work in samsung messages on unlocked Verizon no matter what you do. I had also followed another thread to get RCS working but it turns out it's a Verizon thing that is blocked on unlocked USA phones. Flashing Verizon firmware gave me that feature, but I eventually went back to XAA because I just use Google messages now.

After unsuccessfully trying to root latest DUB5 firmware form T-mobile with Magisk - found a solution:
Samsung apperently changed vbmeta in ONE UI 3.1 so we need to wait from vbmeta 3.1 disabled.

1. Patch original T-mobile AP with Magisk.
2. Replace BL_N986USQU1DUB5_CL20936746_QB38027387_REV00_user_low_ship_MULTI_CERT.tar.md5 with other BL image from Android 11 (One UI 3.0 XAA will work).
3. If you do not repalce BL file, you will get an error "vbmeta_fail" and your phone will get locked.

The t mobile euicc is looking for 30.0.6 version before it will install and run correctly.
I can't mount it as editable to look for just 30,
Any ideas, unpack on my laptop and edit that way...
If I put it to look for 29 and up it should work. I got it to back door install but it's,not writing profile cause version it's looking for ain't there yet

I can attest to that , briked mine 5 times

What exactly are you trying to mount? What is 30.0.6? Verison of euiccservice?

looking into the tmb euicc file i got from you, you know how thye look for version of android to run and install on, this one is looking for 30.0.6 to install on, open up the installer package and in the android manifest, in complie version sdk it says 30.0.6 for version name r.0x1 android:versionName "30.0.6" like its looking for highr version than is installed as om sdk 30
i found a retorfit installer inside the package that writes the kotlin to metadada but looking at install log it freezes after it sees im only on sdk 30...was thinkingif i could modify the version it was looking for to 29 and up that it might install correctly maybe 30 and up because file system is way different, i cant edit the file though , im going to try to open on my laptop and see if i can modify...but thats project for tommorow...theyre laying foundation to enable but this should have been back in 10 like they promised, i got it halfway working and it found and added my plan but wont make or recive callss as it cant fine imei for esim ......

Ok ive seen a lot about the esim but what about the dual sim option? or does the snapdragon model not have the slot for that? I know it doesnt com with the dual sim tray and its obviously not as easy to just get a new tray and pop your sims in. But is it a software or hardware issue for it?

I have euiccservice running on TMB DUB5 firmware natively. 30.0.6 is the actual verison of euiccservice.apk, NOT SDK. Min SDK is 30 and Taget SDK is 30 as well. Still cannot get eSIM to work, it gives me "Invalid chip on eSIM" whne trying to add plan.

I flashed AP from 9860 into 986U1 and it does appear with 2 physical IMEI numbers. BUT the SIM is not recognized in secondary slot (I bought a tray with DUAL-SIM from Exynos verision) so no LUCK.

A dual SIM tray will fit, however there are no SIM contacts for the second slot. Only contacts for an SD Card.
First IMEI is for the physical slot, second is for the eSIM.

 

[Fluke1979]

ok so how do we get the esim activated then? with unlocked bl this should be possible now right?

 

[a43]

hey guys, I am wondering if there is a way to open modem.bin file system somhow on computer? I want to check mcfg files from 986B phone and try to apply them on my 9860 as mentioned on 13-14 pages here...

 

[a43]

Do you guys have anything in this UE menu (LTE BANDS & CA COMBINATION)? I'm trying to set aggregations and don't find a way to do it. On recent firmware update I see 4G+ sign is way less often and using NSG app I can see that phone tries to connect to 2xCA finds second tower and then disconnects.

 

[a43]

What carrier/ country are you in. I can get you CA up to 3dl and carrier features by modification of the sx55 fusion modem file.
This is my map carrier list, bri chc and tgy only have 4 options by default. All the same. But I can add NA SA and some euro carriers with simple copy and paste inside mdm files.

Would you mind sharing these files with me?

 

[a43]

I've been trying to enable CA combos. Unfortunately Snapdragon 865 and it's sx55 modem is not using 00028874 file anymore for carrier aggregations and I've found that TGY (Hongkong region CSC) and CHC (China) firmwares have different CA combinations in /nv/Item_files/modem/lte/rrc/cap/prune_ca_combos files. Also TGY firmwares have additional folder /ca_band_combos with ca_bands_454_06 (45406 is the MNC of SmarTone mobile operator) and it's having same format for CA something like that:

e-3AA-mAll;e-3CA-mAll;e-3CC-mAll;e-3AA-3A-mAll;e-3AA-3A-7A-mAll;e-7C-20AA-mAll;e-20AA-7A-3AA-mAll;e-38CC-mAll; etc.

I`ve created my own prune_ca_combos list and ca_bands_ files for 25001, 25002, 25099 - I live in Russia and those are Russian MTS, Megafon and Beeline MNCs. I can see my newly uploaded combos in *#9900# logs and also in UE Menu *#*#27663368378#*#* Protocol state - AS info - LTE PRUNE CA COMBOS page they are there but looks like my phone is not really using them. I have an old Samsung S10e Exynos as well and it always gets LTE 3xCA if I check *#0011# code while my Note 20 Ultra 9860 Snapdragon only connects to LTE 2xCA sometimes and doesn't use ULCA. It's weird and I thought maybe someone here knows where we can read more about it or where to dig in the modem or firmware together?

Would you guys be able to post your prune_ca_combo files from different firmwares of different 986x phones you have? You need QPST for that.

So, I've read in several places the US N20U has eSIM. I see the eSIM control app is in stalled. But that's all I see of it. Even an article here on XDA says all N20Us have eSIM except Japan, Korea and China. Can anyone confirm? And if so, how? (I've never used eSIM)

Pretty sure it's for google fi
