Remove Verizon Boot Splash Screen

Hi,

I upgraded my S8 to a S9 and would like to sell my old S8 as an unlocked device.

I was told that being that the phone is paid off, It is unlocked, and can be used on any carrier.

This is great, but am wondering how to remove the Verizon Boot Splash screen and the pre loaded Verizon applications after the device is reset.

If I were to buy an unlocked phone and were to use the device on a different carrier, I wouldn’t want the Verizon bloatware on my device.

Is there any way to get the stock android firmware on the device. As if it was bought directly from Samsung?

And if not, do you have any suggestions for the best way to go about selling it as an unlocked phone with all the added Verizon crap?

Thanks,

Taylor

Verizon phones will not accept any custom ROM. This has been done this way since the S4/Note 3. The way Verizon locks their bootloader effectively prevents other ROM’s from being installed - even the reference Samsung ROM from the Unlocked by Samsung series. AT&T is also guilty of doing this so Verizon isn’t alone. IT HAS to be the carrier specific ROM or it prevents it from BOOTING.

The feature Verizon uses is known as Samsung KNOX. They use boot signature enforcement, which verifies the ROM signature against the “correct” signature. The phone will not boot without the Verizon ROM installed since the signature varies per device (Unlocked, T-Mobile, AT&T, Verizon, Sprint). This “feature” prevents you from removing the Verizon ROM or modifying it to remove the bloatware. Root can be used to "force” it off, but you cannot change the ROM to remove it permanently.

How I’d sell it is I’d sell it as unlocked for any carrier, but explicitly mention it’s a Verizon phone. This is sufficient because while it’s SIM unlocked (FCC open network license requirement), it is still a Verizon phone. It will also deter buyers who want the ability to tinker with the ROM, so you will not need to worry about the KNOX 0x1 flag being tripped and hurting the resale. You are better off losing a sale from someone who opposes Verizon’s lockdown practices to avoid getting a tripped phone back.

I figured as much :/

Hopefully the buyer won't mind!

Yeah... There's a reason that the AT&T/Verizon phones are unwanted (or strongly disliked) by buyers who care about the ability to tinker with something they own. It doesn't bother everyone, but buyers who want the freedom to tinker with what they have will overlook them entirely.

The problem is if you're on Verizon, you can't use a tinkering friendly model unless the IMEI/ESN range is in their system. They don't like to approve phones that aren't locked down for that. I've added my advice to the answer.

If you buy a phone direct from let's say Samsung and use it on Verizon's network do they still use their boot rom forcing their splash screen on your device, and is it then un-removable in that case?

@Gordon No - this only affects the Verizon V/VZ 5G SKUs (Ex: SMG781VZBV). However, today they're using 5G to force people to buy branded hardware because they use a 5G band literally nobody else uses.

I'll pass on 5G until everyone stops using it as a circlejerk to break cross compatibility. Not much faster, more expensive plans and broken carrier cross support... I'll let people beta test the future incompatible devices and buy in when the bands are known (especially the FU for buying from anyone else like the Verizon UW one).

I guess you can remove not just bloatware but anything from any cellphone with a Pc, Minimal ADB and Fastboot installed on it and app inspector on the phone.
