[Q] Do I really have to enter a password?

okay. i decided to buy the A500 tonight. after reading all the threads, it sounds like a good purchase. but when i looked at the demo they had on the showroom floor, it had a password on it.
i don't plan on putting a password on it. i just want it next to my bed and not have to worry about it. what i'm worried about is someone (like a friend) putting a password on it. the reason i ask this is because when i was looking at the demo model tonight, no one knew what the password was...so i "soft" reset it via metal wire into the reset hole AND also by holding up on the volume rocker. but in either case, it didn't do anything except for pop up the Android guy with an exclamation symbol. when it rebooted, it was at the password lock screen again. nothing changed.
after looking here for related threads, it says that if you don't know the password, then you're in deep kaka doodie (it has to be sent back to Acer).
i don't know how many of you still remember what CMOS is, but in order to set a boot password, you have to know the master password (which you need to know in order to make any CMOS changes to begin with. such as enabling the boot password option). that way the person who built the computer will be the first and only person to set the master password, preventing his/her jerk friends from pulling a prank by preventing him/her from booting their computer.
so my question is: is there a "master" password required to set the lock screen password?
my phone has a password/pattern. the reason i have it is because i leave my phone at my desk at work or on the coffee table at my friends. and i don't want them looking at my stuff. but the tablet is gonna be in my room and i don't have to worry about anyone looking at it or stealing it except for myself.
another question: will the custom roms bypass this password feature?
thanks for reading this far. sorry if i'm asking stupid questions, but i guess after the frustration at the store tonight with the demo model, i'm a bit annoyed. i never got to actually use the device and i still bought it anyways on the grounds that i would be happy with it (that sounds dumb now that i think about it). heck...its still sealed in its box & sitting on my bed as i'm typing this. but the password feature really sounds like a danger.
EDIT: the reason i'm asking this right now is because i JUST opened the box and am now charging it (for at least the recommended four hours), but i'll be asleep in a couple. so i won't find out til morning. but i'm hoping an XDA boarder can fill me in before i catch some Zzzs.

As far for a master password I've no idea if there's one...
Regarding installing new Roms, yes it will reset the password. I don't know if it's because the CWM wipe and factory reset but it will clean any password you have set.
You can use the tablet without any password. It's very easy to set it up under adjustements/security.
And I do agree with you that having a demo pc/tablet/phone is the most idiotic idea of marketing or sales strategy I can think off.
I've got my Iconia for 5 weeks now, gone trought a few roms, got back to stock but in the middle I've learned the "how to..." At the end I'm so happy with this tablet and how flexible is that I'm recommending it to all my friends.
Hope that helped.
Cheers,

very helpful. thank, mate. cheers!

just for your info, the ICONIA A500 is delivered without any obligation of using any passwords of any kind. In the showroom they have encrypted the tablet to protect it it from any unauthorized use.
In fact only if you want to whether protect your tablets content to be visible if ever it is stolen, or if you want to use enterprise (exchange activesync push) email capabilities, you have to encrypt your device, which then will oblige you to enter a master password during startup and a PIN password to exit sleep state.
So of corse no password protection except if you want it.

Nexus 6P angler-userdebug 8.1.0 question

hello, my first post, I bought a Nexus 6P from ebay. It has an unlocked bootloader (I get the warning when I turn it on) and the os build number is "angler-userdebug 8.1.0 OPM3.171019.01445.3998 dev-keys". there are applications that are not uninstallable: Better Bug, Nexus Logger, Traceur, and Volta. My question is, is this device suitable for personal use the way it is? any other information and/or suggestions are appreciated.

I am not sure about the rom version.

It sounds like somebody sold you a former test model from Huawei.
I can obly assume, that they sold remaining units, but after I searched a bit about those applications I can, like I said, only give you a vague assumption.
The important questions are -
Is the phone functional?Meaning: bootloop, sudden reboots, battery problems?
Are you able to use adb/fastboot? - > Is your phone being recognized by the command 'fastboot devices'?
Did you get a notification that is your system can be updated?
The unlocking of a bootloader isn't a reason to be distinctively suspicious?
But, if you are not satisfied with the phone in whatever way, you can demand to be refunded in regard of the unlocked bootloader with the argument, that the seller has tampered with it and should wrote it in the description.
I bought a phone a while ago and were unsatisfied with it, so I argued with the above mentioned and got my money back.
This was even from somebody private and there are no refund policies, besides the buyer protection.
If you have not passed thr chance and don't want to have a phone, which somebody has used most likely to flash a custom rom or recovery to root same phone, then go for it.
It is not a 100% bulletproof argument, but ebay excepted it, at leat in my case.
If you are okay with the device and adb/fastboot are working, in a way that you for example can test some commands, whicj you have to look up, but __don't flash anything__ as long as you are unsure of the condition.
If you want to remove these apps, you have to look them up, which is expandable and which isn't, before removing them.
And lastly - if you want to remove them, you have to root your phone (tutorials find you here en mass, the same goes for adb/fastboot usage).
But the same goes here for testing a ADB and fastboot usability, please.
If you decide to keep it, then you can remove system apps (>before a search if you phone goes boom..), aith this app for example
https://www.apkmirror.com/apk/jumobile/system-app-remover-root/system-app-remover-root-7-1-release/
With this, you are able to backup the apps if you want to remove them.
Some apps, especially the so-called 'bloatware' is from now on then, quite resistant.Just empty the trash, which you find in the app's menu.
Titanium Backup, a very, very versatile application, is fir example capable of backing up your entire apps including data, but I think, you have "some" pointers now and can give it (with carefulness) your own try.
Have fun & good luck

Xtrons PX5 PBX79ATT suddenly loses all BT

I'm a long-time programmer, but this is not a programming question, and I'm not even sure that this is the right place to ask this question. If not, my apologies. I cannot find any real Xtrons support anywhere on the web. I have emailed them, but have not received a response, and I'm impatient.
I purchased and installed an Xtrons head unit, and it worked OK for a few weeks. This morning I went to breakfast and was able to play music through BT into the head unit. After breakfast, all of my BT pairs were gone, and when I scanned to see local BT devices, the scan never terminated: it went on forever. Attempts to pair to the head unit from my phone failed. BT is suddenly totally dead. I've power cycled the head unit (turned the car off and on) repeatedly.
Not sure if this is a driver, software (OS), or hardware issue. Not sure if there is a BT antenna that could have been shaken loose. I can't see any way to force the Android device (the head unit) to do a normal power down as one would with a phone or tablet: the "power" switch seems more like a "sleep" switch. There are two BT-related processes, which I can see, one of which I can force to terminate, the other of which I cannot, but that has not helped. I cannot see any way to clear the cache or data for these processes. I'm looking for some kind of "reset", without joy.
Any hints would be appreciated. Assume that I'm somewhat experienced at Android use, but not at Android development.
Thanks
Jon
Edit: I stumbled upon the hidden location of the Reset button. Once I reset the unit, the BT functions returned immediately. There documentation does not include a photo of the front of the unit, so finding the Reset button was not obvious. And many emails and an hour on a chat session did not have Xtrons support suggest a Reset. Anyway. It's working again.

What do you think about to secure the HU to prevent giving access to the stealer?

What do you think about secure your unit by PIN or Password? Do you use it?
I think it is a good idea, if the car or unit get's stolen the system would be locked and i'd have time to change my google password and remove the connection to my account.
But it is a little bit tricky to find these settings, because they are mostly hidden.
Tell me how you think about it.

Just install Google Find My Device and send command to wipe device. Even if it is turned off, as soon as the device gets online, it will be wiped.

Bypass the lock screen

Hi all - I imagine this has been asked a thousand times before, but I am new here and in need of some real help.
My brother recently passed away, and his phone (Huwei P Smart 2019) mysteriously went into Airplane Mode, and has no sim card. The lock screen is on and none of the 'usual' numbers or patterns he used appear to work. This phone was his lifeline before he died, using it to speak to doctors and care workers - which is why I do not think he set it to airplane mode himself.
Shortly after he died a 'friend' went to his house to 'secure valuable belongings' and he had my blessing to do so. When I managed to get there, and secure those belongings myself, lo and behold the phone was locked.
Apparently, it does this when it powers up after the battery drains. Apparently, (according to the 'friend') on a reboot it shows a lock screen... and somehow goes into airplane mode. All I know is his two other older android phones do not have passcodes and all are open and accessible after a reboot - I've already been able to check these for data easily enough. I cannot even see what version of the OS is installed, but I'd guess it is the default that the phone came with.
I am not an Android user, and am certainly not a 'power' user of any device, so I don't know if what the 'friend' is telling me is total BS or not. What I do know is there is likely to be some essential information stored on that phone, let alone photos and memories that his family would like - I am specifically looking for any details of his medical treatments and messages he might have received just before he died.
I've trawled around countless 'phone repair' booths in countless malls, and everyone tells me the same thing - it can be opened, but you have to wipe the phone. Obviously, I don't think that'll help as a) I don't want to reuse the phone and b) I need the data from it to help with an ongoing case.
So, the question is, can it be done... and if so, how?
Thanks in advance to all who reply.

Not sure if I believe the story.
Probably with testpoint, with unlocktool, with chimera, with EFT dongle.

I've tried some methods the testpoint methods I tried all erase the data.
All other working methods are on youtube search for huawei frp without data loss and similar search strings, and click on Related videos.
Don't connect the Android to Internet to avoid security update.
Try the method with sim card with PIN however that may need a previous version security.
If there is important data wait some time and check youtube again however there are fake videos on there.
If it's too important probably someone can attack it through some method.
However if you have no good reason to attack this device better move on I do not believe the story with deceased relative and whatever is on the device maybe it's water under the bridge move forward. If not then it is a high cost in your time effort money patience better invested elsewhere.
Whatever the case not judging
