I'll try again as soon as I get home. thx so far

Edit: with what last hexpatch line did you patch? from first post or the one mentioned somewhere on page 10:

Hi, I know the FAQ says it's possible to update magisk via manager. Knows magisk manager how to properly restart the device if I let the manager restart?

Thx
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
same.... choose restart... after choose restart press vol up and bixby until red warning appear...
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
Sadly this doesn't work. Updated and flashed via manager, restarted and pressed vol up + Bixby and released it when warning screen appeard.

I had to reflash patched ap

Edit:

So if I reflash patched ap + home csc and trying to patch the kernel following happens:

See pictures

After that I have to reflash patched ap etc again..

Magisk isn't updated via manager also because I should have left it as it was..

OEM-Unlock isn't greyed out as well.
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
After reflashing the patched ap I can't patch the kernel anymore. Always stuck at the screen above :/
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
i ever had that screen...

when i upgrade to SH2...

all i have to do is... reflashing rom with odin... but not magisk patches Ap but stock AP.

get in system.. re enabled developer setting... usb debugging etc.

then after that... i reflash again with patches SH2 AP and home csc, boot etc..

after flash... must go to recovery and wipe cache. then reboot.

thats what i remember...

but to which magisk you update ?

because I'm still using 19.

i dont use beta for this time
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
I have updated magisk via magisk manager (see Screenshot). I've already had a patched AP file.

In 1st or 2nd post it is written that updating magisk via magisk manager works.

But if I let the device restart by magisk manager after updating magisk it doesn't boot anymore. It only boot into kind of download mode. Even with the key combination vol up + Bixby pressed it does not work.

Then I have to flash patched ap again and I'm able to boot again. But after that patching kernel isn't possible anymore.

Every step for patching kernel runs without problem via adb shell. But after reboot the device stucks in download mode shown in my last Screenshots.

Weird, I don't understand this.
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
i can't get out of the semi-download mode :(

i've even completely restored stock with factory reset to reflash everything from scratch.. but nothing..

:(

is it possible that I've to restore original kernel? or remove the patches? because this happens to me since patching the kernel.

thanks
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
i think when you flashing all stuff with odin... with csc... not home csc... you already restored to stock.

---------- Post added at 14:20 ---------- Previous post was at 14:18 ----------

sir [MENTION=235313]qwerty12[/MENTION] .... new updated rom for tgy already released... with more features updates.

https://www.sammobile.com/samsung/g...e/SM-G9750/TGY/download/G9750ZHU2ASIK/294817/

will you have a time to check if the patch still valid ?

thank you..

* still downloading the rom... but maybe sunday will try it*
[Samsung Galaxy S10 Guides, News, & Discussion] qwerty12:
Yes, you flash AP again. I've ran into that many times during the testing of this, but I've always been able to flash just the kernel and all has been well. On that matter, I've intentionally started my phone without Magisk at times (Xposed module conflicts) and I've never had a problem with being able to use Magisk again.

[MENTION=2780783]Vuska[/MENTION], I'll check when I have it downloaded (no ETA, sorry), still running ASH2 here :)
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
i only have home_csc or am i missing something? I've to check again if extracted firmware zip contains another csc file.

I've already flashed several times stock AP. but everytime I flash patched ap again I run into this semi download mode. I can't pass this screen without flashing stock. first it worked with patched ap, patching kernel also. but after updating it via manager it always stucks at this semi download mode.

I'll try to recover completely stock one more time.

to restore stock I only have to flash ap, csc or home csc, bl, etc.? or do I have to lock boot loader again or something else?

and another question. I'm on stock right now, without root,without patched kernel, etc. but if I wanna use Samsung pay for example it says it can't work because I'm rooted. how does this comes?

big thanks for every help!5
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
i guess flashing csc not home csc was the right hint. i'm able to boot with patched ap again.

its rooted and everything works.

BUT a big BUT updating magisk via magisk manager does NOT work. after rebooting it stucks at semi download mode.

i now hopefully know how it works and what doesnt work.

after flashing patched ap again there is no semi download mode. guess flashing with CSC restored to stock properly. but updating via magisk manager does definitly not work.

edit: so now after patching kernel i'm again stucking at semi download mode. what the hell i'm doing wrong?

[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
does anyone of you have any other idea why I'm always stucking at this semi download mode?

I flashed back to stock: with Odin AP, BL, CP and CSC, not HomeCSC for fully restore.

After that i flash patched AP by magisk. this works as it should and the device is rooted.

then going to adb shell into device and do exactly what I did the first time to patch the kernel.

There is nothing which i didn't do the very first time as it worked.

but now.every time patching the kernel I get the semi download mode. it's the first screen you get when starting the device with “Samsung Galaxy S10 etc. but with infos from blue backgrounded download mode in the upper left corner.

I can't explain it. Damn I just want my device to be stable as before I flashed the magisk update via magisk manager.
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
before doing patch are you already get into android os ? (finished restart and setting... check developers setting too ?

everything must be work... if you do it step by step.
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:
yes, everything works. i already used Titanium Backup, etc.

what I've noticed:

1. OEM lock was greyed out before flashing the patched ap.

2. after flashing patched Ap the device was rooted, but OEM lock wasn't greyed out anymore in developer settings.

3. in semi download mode if you take a closer look it says “OEM Lock: ON (U)“ see attached screenshot pls

does this anything mean as before patching kernel it was OEM unlocked in dev settings?
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
Yes... (U) mean unlocked.

i think i dont do anything different ... after flashed stock.. i get in system.. setting all i intro setup... go to developers.. and yes... once i ever not seen oem unlock in developers... so i remember i plug out simcard (i forgot where to see about this)... then back to developers setting and oem unlock is there...

then replug simcard.

Patch Magisk AP, rebooting... press vol up bixby until red warning... and it done.

strange.. [emoji848]
[Samsung Galaxy S10 Guides, News, & Discussion] redplate:

No chance. as soon as i flash patched ap or patch kernel i'm in this semi download mode. i really don't know why this happens. Could it be that something went totally wrong while i updated magisk via magisk manager?

Nothing to do with this patch. I updated Magisk from its manager to 20.0 from 19.3 and it also ********ed my phone, like it did yours. G9750TGY2ASIK, no kernel modifications, just Magisk 19.3's modifications to the AP image.

It's up to you, but I think most people just use Frija or SamFirm...

how do i flash 19.3 only? if i patch ap with magisk which version to i get?

latest manager is v7.5 with magisk v20..
[Samsung Galaxy S10 Guides, News, & Discussion] Vuska:
maybe use other phone with magisk 19.3 to create AP... or... after you clean flash stock with odin..installing magisk manager then make sure use stable for magisk source in magisk manager setting.

then patch the AP.

as i remember the stable magisk still v19.3,

edited : aahhhhh just check... its already v20..

how did you manage to flash 19.3 instead of 20.0? Could you share please? Would be really great.

[Redmi K20 / Xiaomi Mi 9T Questions & Answers] sinners007:
The official Xiaomi website suggests the Mi9T supports LTE FDD: B1/B2/B3/B4/B5/B7/B8/B20/B28. However many sellers have told me that their Mi9T does not come with Band 28. My understanding is that the box itself doesn't show the bands of the phone but the booklet inside the box does - thus perhaps confusing some sellers.

So, my questions is, does anyone have a definitive answer if all Mi9Ts have the same bands and more specifically, do they all come with Band 28 (700Mhz)?
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] Cardos0_:
I want to know this same exact question.

Because here in Brazil many resellers don't know if it has or not the band 28 (700Mhz).

[Redmi K20 / Xiaomi Mi 9T Questions & Answers] sinners007:
Xiaomi make different phones for different regions with different Bands. We can't rely on their website either. It says that the Redmi Note 7 has Band 28 but the RN7 has 3 different variants, only one of those has Band 28.

My question is whether the Mi9T is like the RN7 with different bands for different regions or whether all Mi9T have the same bands?

[Redmi K20 / Xiaomi Mi 9T Questions & Answers] sinners007:
I am asking if ALL Mi9Ts have Band 28. Many sellers don't list the bands for the phone and other sellers say it doesn't have Band 28.

GSMA claim that (unlike other phones like the Redmi Note 7 which has multiple variants) the Mi9T only has one variant which has Band 28.

Does anyone know the official answer?
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] toobywedge:
I just got my Mi 9T from TobyDealsAU today, and the booklet says it has band 28, but in the cell info app band 28 isn't appearing... When I put my sim in my Mi Mix 2 it connects to band 28 instantly, bit disappointed...

Maybe it's something to do with MIUI Global, going to try flash Xiaomi.eu in a week when I can unlock it, still disappointed though
[Redmi K20 / Xiaomi Mi 9T Questions & Answers] HockeyLan:
Straight out of my instruction manual in the box

1/3/7/8/20/28/38/40

which is not accurate because it supports band4 too. I guess since it's made for Europe they don't list it there. The best way to find out is to check FCC or similar regulatory bodies with the device ID.

---------- Post added at 09:25 AM ---------- Previous post was at 09:02 AM ----------

Ok, I looked up on FCC. Mi 9T https://fccid.io/2AFZZ-XMSF10G

If you look at the LTE reports, it has approve cert for these bands.

[IMG="FCC"]https://i.imgur.com/6nczILe.png[/IMG]

I don't know if that's conclusive since band 28 is Asian maybe FCC doesn't test that. Overall I'm guessing this device doesn't support any 700Mhz band like 28 or 12 etc.
