@Tech = Spy-Biz kbank-811 v537 got working with usnf modded version
Yup v537 working.
( FYI, I used Android 11 GSI + USNF MOD Version + Signature Spoofing Enabled + microG Gapps Module with microG-GooglePlayStore frozen + 6 Services from v537 disabled + I installed v537 from aurora ) So thats either a miracle or the KB app Dev had mercy on KB clients

ICICI iMobile from Aurora is working too .
RBL Mobank detects Developer Mode ON & also detects Aurora download & installed using package installer, so wont work unless google Account present which means have to keep that peeemp-azz playstore app inside the phone with a peemped-azz gmail account on the phone, I find all this unnecessary on part of the bank bcoz i know one of the older versions of KB App was working with Superuser permission from Magisk app

.
If a bank app asks for SU permissions to work then thats a tradeoff the bank customers wouldnt really mind much bcoz there are plenty other possibly shady apps like SeFix App (malware flagged by Malwarebytes) using root privileges as well (I uninstalled it ofcourse).
I just wish the bank acts more maturedly with its customers coz its relation with its customers is a financial one not to spy on its customers which thankfully its not doing uptill now. By the word "Maturedly" I meant the banks should allow their customers to use rooted devices and should rather focus on other means to find out if security breach is happening real-time or offline remotely from a cloned SIM Card etc. For example -The banks can have some kind of software to check with their customers Mobile Carrier if there are multiple SIM cards registered under the same phone number, that would be better than to cause incovenience to its customers by not allowing them to use their bank app on rooted devices. It doesnt make any business sense unless google is paying/forcing the banks to make their customers use google accounts and Gapps. Thats really sick man! They can just create 2-step Verification or maybe 3 or 4 step verification for their banking apps instead of forcing clients to use google. Absolutely sold-out garbage peemping going on between the banks and google admob. I'm sick to the point of vomit looking at how LOW google is ready to stoop just to secure mainly one presumably sweet corner of the world and to make ships full of spy-money! What a PEEEEMP!
