Hi.
I currently have Sony Z5C, but it's slow as hell with encryption enabled, so I'm planning to get s10e and (obviously) root it.
As far as I understand some things will become unavailable, like SHealth and SPay, but those I can live without.
Will whole partition hardware-accelerated encryption still work though?
Thanks, Oleg.

Has anybody here used the built-in honeycomb encryption feature? From what I understand, and correct me if I'm wrong, your data is only encrypted when the device is off? If that's the case, I'm not sure what help it would be since I generally leave my tablet on 24/7.
For those of you who have tried it, does it slow the startup/shutdown process at all?
Are there alternative encryption applications that can keep my data safe even while the tablet is running?
US998 unlocked and rooted.
For a completely offline device, is it possible to disable gps amd cell radios in the firmware and/or flash an incompatible gps version and still have the device boot? Something that makes it impossible to enable them without reflashing the entire phone.
Can the service provider be prevented from pushing app updates? Changed providers and an emergency alert app was installed whereas before it was hidden away in settings.
Thanks!
You can try flashing an incompatible modem, which is the communications driver for WiFi, cell and, I think, GPS services. People occasionally do it accidentally and lose services until they flash the correct modem.
Perhaps an easier solution would be to see if you can find an app that can do it, though... either a business app that can disable all communication for security purposes or a parental control app so that parents can restrict usage on their kids' phones. Either way, you might be able to lock it with a password so that you can enable it from time to time for emergencies or to update the apps through the Play Store. I know that you said that you want it to be impossible to undo without reflashing the phone, but perhaps a less drastic solution would suit you better.
As for the service provider pushing app updates, if you disable the cell service by either of the above methods, they shouldn't be able to do that. You can also simply remove the SIM card, instead, if you're using one. Finally, you can install a 3rd-party ROM, like Havoc-OS, which I'm using. You might consider that if you really just want nothing to do with service provider or LG bloatware. There's no need to disable communications and make an offline-only device if all that you're really trying to do is make your service provider and LG leave your device alone.

Congratulations on successful bootloader unlock and root. Thanks for telling us the model number.

Good options. The only caveat would be NOT to use T-mobile H932 modem. It is so incompatible it will brick a US998. For US998, flashing one of the H930 variant modems (H930, H930G, H930D, H930DS) over US998 would probably do what he wants. Very good suggestion.
I can't remember where there's the TWRP flashable modem files are, but I know they exist. Because some LOS users have had use them.

I'm guessing he's trying to prevent any digital footprint for his own reasons and from something being enabled on the backend without his knowledge. Like how it's been proven turning off "location services" still doesn't prevent Google from tracking you...

Thanks for the replies!

ChazzMatt is correct.
Want to confirm that gps is part the main radio firmware?
Probably not advisable but can the modem file be successfully edited?
Hello there! I was a relatively early adopter of Android and while I am not a programmer I am a nerd who can follow directions. I like to dial my devices in and maintain as much privacy as possible. I really don't like bloatware and when I was still working I would buy from Google rather than a pre-loaded cell. Now I am looking to get back to work and broke. I lost my last phone and got a lifeline (free) phone. It is a SKY Elite H55 with AndroidGo installed. The last time I had to use one of these phones I just took the sim card out and installed on a Motorola E5. For whatever reason I lost and had disabled location. While I am grateful to have cell service the Go phone experience is terrible and all I could manage to do is setup a wifi hotspot for other device. Just navigating menus was terrible and this one is newer but seems to have even more restrictions and less options. Also I have a thing for reading ToS and dont think anyone needs my data free. When I powered on the device I saw this as one of the only settings:
Allow Scanning: Allow apps to scan for wifi and nearby devices even when wifi or bluetooth is turned off.
What is the actual fudge is that? It BS and no I dont want that. I have not activated phone and qwould like to make this a more stock phone that just does basics. I can make calls with google voice on my iphone 8 all I need is this as a hotspot. The idea a default setting lets apps scanat will even after you turn of wfi/bt is offensive. Do I have any options.
Whatever I lack in skill I try to make up for by reading and following directions. I just did a complete softmod on a olld Nintendo DSI and it turned out perfect so I am ready to own my device. If possible. Danke.
Basically the title. Extremely tempted, but not if that's going to be an issue.

Yes, but... VoLTE always works, but VoWifi only works when you use the dialer code after each reboot

Is there any hope of it being permanently enabled?

Probably can if you root, I haven't bothered to check since I don't care about VoWifi unless I need it (very rare), then I enable it.
They might release an update too, who knows.
The vowifi issue messes up my 5G and mobile data completely until enabled. A fix from ASUS seems very unlikely because its been an issue since zenfone6. It hasn't been that big of a deal after figuring out the couple steps to follow after each reboot (which isn't that often): https://forum.xda-developers.com/t/...stability-fix-with-root.4490423/post-87497837
Great phone. I recommend it.
Just got the phone and love it. Noticed 2 issues with 5g/Vowifi:
* 5g was off by default. After enabling it it worked, but occasionally phone would lose carrier (would not be able to receive any phone calls)
* vowifi works after using the dialer code, but doesnt persist after a reboot. There must be a way to make it persist?!
First, to clarify, I have the Samsung Galaxy A21 (there is no dedicated forum, so it seems we A21 users must use the A21s forum.) Although this may at least somewhat apply to the A21s (it may actually have the advanced service menu, so may at least have that as an option. The A21 is considerably more gutted in even the most basic functionalities.) One bit of confusion on my part is the actual SoC is a MediaTek, not a Samsung Exynos. However, all warnings regarding these exploits list "A21" so I'm assuming that the modem may still be a Samsung modem. Though of course it may just not apply and they really mean the A21s (these models are so completely different they really should not have been given the same number,) I have no choice but to assume the A21 is included until someone says otherwise.
The main vulnerabilities are these four:
CVE-2023-24033
CVE-2023-26496
CVE-2023-26497
CVE-2023-26498
Apparently there are 18 in total, but these are the ones that allow "zero click" remote code execution (presumably with at or near root access.) One thing I've been unclear about though is if you have to actually accept the call or not. The implications of the warnings seems to be that all they need is your phone number to initiate the exploit (which would mean that bad actors could just simply use an automated system to run through basically every number if they really wanted.) Though to me it would make the most sense if it actually required you to accept the call. (I'd really like some clarity on this as that would mean simply rejecting any call not known to be safe would usually be sufficient.) For now I have to work with the assumption it truly is "zero click" as they describe it.
Given that VoLTE is normally not an option the user can toggle (especially in recent ROMs) there seems to be basically no way to turn it off these days. Phones used to sometimes have a toggle in the cellular settings, but not anymore it seems (probably due to it being basically required now.) I tried to enter the advanced service menu (*#26833662#), but it said not supported when I did. The standard service menu does not have any options or controls (let alone anything regarding VoLTE.) I remember in the past on an older (less locked down) phone I did have options to enable/disable VoLTE (though it didn't work due to the hot flaming mess that is VoLTE -- it really should have been required to be standardized and enabled across all devices physically capable of it before the 3G cutoff) via one of the service menus, but unfortunately this one doesn't seem to have that. Is there any other way I can disable it and at least keep my cellular access? I realize this means data only, but that leaves at least some possibilities such as VoIP calling like Google Voice and, more importantly, does leave me access to online things when I don't have WiFi.
It should go without saying, but I do have WiFi calling off, so no issue there.
Bump. There is still no security update on mine. There may never be. I wouldn't be shocked at all if it's abandoned at this point. Even just a data only connection would have to be sufficient until I can come up with a better phone solution if that's what it takes, but I need to at least be able to use it for some basics on data, so removing the SIM isn't going to work.
