[Q] Help me in flashing firmware of One M8

hey, guys. I'm new to android. I bought a HTC one M8 used (not totally, it's a phone of a HTC developer I think) yesterday. But it's firmware or android is weird. First I thought it's a clone but it's real. All HTC features are present. But another weird thing was when I updated a new build, a girl named Jennifer showed up like first time on my card & a bunch of contacts saved. In details I found out all of them are HTC developers. So, I think it's a real HTC one M8. It has a demo app which stay open when display sleeps, prevent it from sleeping. Also many settings are locked. Like power saving quick settings, Airplane mode. Also it's in full brightness & both quick setting + main setting is locked. I can see & trap it but don't work. Most of the settings are locked including developer options. It's white & tapping on/off doesn't work. The retailer shop keeper said flashing a new firmware will solve it. But their shop is really far away & I've no ideas on android firmware flashing. I know about Symbian flashing though but that's no use. Please somebody help me. I need a procedure for flashing & link of M8's firmware. My phone is Europe version. & also it'd be nice if you can tell me how can I see or edit my external memory card. Please help. Thanks in advance

Try to do a Factory Reset first; it looks like it's stuck in Demo mode.

Okay. I'll try it out & reply. Thanks

The"ok" in Factory reset is locked too. I'd upload a screenshot but I dunno how to. Please help. I think flashing is only option. But I dunno how to flash or dunno firmware link

You don't know how to take a screenshot? Hold power button and press home button at same time.
Good luck with getting it sorted! Can't you ask the previous owner for help or do you not know them?

Dude, I know how to take screenshots but dunno how to post in XDA. And I thought my phone is used cuz a girl from demo app was set up as user. Then I found out their is a about 700MB zip file with those pictures and stuffs. Whatever, I'm gonna try hard resetting now. Wish me luck

You can factory reset from bootloader or from stock recovery.
To get to bootloader, press and hold power + volume up. Eventually the phone will shut off and the screen will go black. Let go of power and volume up. Press and hold volume down until the bootloader comes up.

I used stock recovery. I'm trying to install TWRP with one click root kit, the developer option is disabled but usb debugging is enabled & HTC One drives are installed. But get token isn't taking my phone to boot loader. if I succeed in installing super su & twrp, tell me how to remove the demo app?

Hi
So I changed the PIN on my tablet and forgot it. Now I am trying to get in and I cant, I assumed there would be an option to log in with my Google account, but I do not see that option anywhere. There is no forgot password button like most phones for some reason. Is there no option for this at all on this tablet? I've already entered the incorrect PIN 60 times, hoping it would pop up asking me to enter my Google account info but no luck. Is factory resetting the tablet really the only way to get in now??!

Company owned SM-P605, pin forgotten by employee, I've already tried Odin with stock rom that worked fine (just replaced the Samsung Boot logo with the telco's one) but it is still asking for PIN!
It's not rooted, and I wouldn't want to, how do you FDR with Odin?
Thanks,

Did you find a way to unlock?

Nah, mate did it in the end. It is possible. I didn't ask how tho.

PIN/Pattern required to enable fingerprint

Why is it when I set a fingerprint, I set a pattern for the mandatory backup security but when I try to unlock with fingerprint it asks for a pattern saying "Pattern required to enable fingerprint"?

As far as I know, as an extra security, a pattern/pin code is necessary when the phone is restarted/ switched on, once you chose to use the fingerprint scanner.

Finally figured it out.
It happens when screen is locked by a 3rd party app, in my case I use nova double tap to lock screen.
Was wondering why (and forgot to mention) it seemed random.
Edit: for Nova users looking for a workaround, if you enable screen off by root access method it will use a secure lock and enable the fingerprint to unlock.

yeah a lot of screenapp does ask.... if you are on elementalx you could use button mapper which gives you the same functionality of double to sleep and more doesn't ask for patter/pin everytime you unlock

This started to happen to me after a bug crashed the phone and had to force restart it holding volume down + power. I only have the default launcher so I guess it's factory reset time for me

For what it's worth, I had the same issue (until I found this thread) and it was caused by Action Laucher 3. The launcher was set as a Device Administrator and was granted permission to "Power screen off". Once I removed that permission my troubles were over.

Seems to me that it makes sense once you have a fingerprint setup, to require a pin as well. Why? Because what if the fingerprint reader stops working? You won't be able to login?!?!
Not sure until the poster above mentions a pattern is required. Normally it is a pin if you want. Then the PIN required upon restart option as well that is there.
Of course, if you are rooted, you can delete the system files that control/store that...but if not rooted with TWRP, you would have to try a master reset I would assume?!?!
IDK...guess I never thought of testing that out...haha

Guys, i hope it's ok if i conquer this thread for my question but i got serious issues here.
Got my 10 back from repair today and restored my backup.
But dumb me it seems as if i set a password/patern whatever and i can't remember it.
So after the first restart i can't unlock my phone cause it's asking for the code (and won't let unlock only with fingerprint) and i can't remember.
All combination that i would have used are wrong and now i got a working phone back again (after almost 2 month of repairing) and can't unlock it.
Is there any way of bypassing/ignoring the restart password or is it possible to only unlock it again with the fingerprint that is stored?
As i don't know what i should do if i don't get my phone unlocked

Try a factory reset via Android Device Manager.

I don't know what Android Device Manager is but I could do the reset in TWRP too. It's about not losing all of my data or a possibility to get that device unlocked without the code. It would be no problem as my fingerprint is stored. Damn, I could just hit my head against a wall or alternatively just cry like a baby. I never forgot a password or code in my whole life and by now it happens

Thx, but there I only have the options of letting the phone ring, lock it down or wiping it. As stated above I could do that easily in recovery, too.
I'm looking for a way of not having to wipe the phone (if there is one....)

To be honest, I don't think so. There were loopholes before, but they have been closed. :/

So doing a factory reset and restoring /data is the only way of getting back control of my phone again (without losing too much data)?
I think i will get rid of locking my phone with fingerprint again as there seems not ot be a failsafe mechanic for forgetting a (backup) mechanic

OK, so it seems that I have to throw that piece of aluminum against the wall. The code seems to interact with /data, because after restoring only /data I have to put in the forgotten password again.

I really suggest starting from zero, when you get everything set, then set a password.

Thanks for your advice, but it's not about starting from zero. I've already done this twice today
It's about at least being able to get (some of) the data of /data

Please help - Sold OnePlus 3 on eBay - Buyer is stuck on "This device was reset" even though I have reset/wiped the device.

The device was sent on the latest OxygenOS.
Thank you so much in advance.

I believe you would need to login to the phone.
The bypass menu only comes up if you reset with either a screen lock active or a google account on the device when you reset.
I am sure when it first came out there was a way around messing with the keyboard or something, but I am unsure if this was patched or not?

this is a google security feature - you need to log into the phone.
best way to do this might be to have them log into the phone and immediately change your account passwords afterwards. not sure what else

Why don't you tell them to turn off the phone, power + volume down, select forgot password and wipe the device? That should be enough to get rid of all previous account data

This system uses a special partition to "flag" the device as protected from factory resets. These will not work.

I work retail and return phones every day; we NEED to remove the accounts before wiping the device, or else the only reasonable way after wiping the device is logging into the account. 2x4 is right.

Exactly the system, wipe the device by flashing Open Beta or unlock the bootloader and flash a custom ROM and wipe everything, reload stock recovery, wipe everything then sideload 4.1.6.
Working retail you can't play around with phones the same as I would with my own phone so you're dealing in a completely different environment.
There are options in place in case someone messes up its not unrecoverable

Will not be able to unlock the bootloader anymore, it needs to be enabled in the OS. If it's not already unlocked it's not going to be.
I also doubt flashing stock OOS would remove the FRP, that would kind of defeat the purpose of having FRP in the first place if you could just go to the OEM's website and flash something in 5 mins.

Why not simply use the unbrick tool? That should return the phone in a factory-like state.

1) Check this article to see if you can remotely remove the device from your end (never tried this myself): https://help.ting.com/hc/en-us/articles/205666168-Removing-Android-Activation-Lock
2) Assuming your account is not full of sensitive data, change your Google password temporarily and give it to the buyer (may be easier to call or live chat them if possible). Once they get in, change your password back. Not exactly safe, I probably wouldn't do this myself. If you do be sure to take caution- 2 step your account after, force log out all devices to your account.
3) Cough up the shipping cost to return the item and try to sell it again. Unfortunately you would have to pay the return fee + lose the original shipping fee.
TIP: Before selling a device, DO NOT factory reset it then box it up without turning it on. Factory reset, THEN test to be sure it goes to the home screen and working properly. You can then reset it again or sell it at the home screen after skipping the setup steps.

For reference to others reading this thread - always REMOVE your accounts BEFORE factory reset of your devices prior to selling to avoid this issue.

There are lots of ways to bypass this on YouTube. I actually did it yesterday. I had to unlock a tablet. If adb is enabled, it's piece of cake.

Encryption

I have the unlocked Pixel 3a XL and would like to encrypt the phone. As far as I have been able to tell, that is not possible with the standard ROM and I would have to wait for another ROM? I do prefer LineageOS since previous phones. Of course, I would also then need to install TWRP which would also need to handle encrypted partitions.

The stock ROM supports encryption, which is typically enabled by default. You can check that it's enabled here:
Settings > Security & Location > Advanced > Encryption & Credentials

I did see that but since I do not enter a passphrase when I turn on the phone I am not sure what exactly, if anything, is encrypted?? The PIN on the lock-screen does not count, of course.

That's normal. Everything is still encrypted/inaccessible until you enter your PIN or password. It's a feature called direct boot that was added in 7.0. https://developer.android.com/training/articles/direct-boot

I looked at that quickly but it does not seem equivalent to encrypting the entire partition which is what I am looking for.

In that case, you'll need to wait for a rom that supports full disk encryption.

Thank you, that is what I surmised. Waiting for LOS and TWRP and for them to support partition encryption.

I am concerned now after reading this. I factory reset a phone that did not have a pin or any lock screen at all. I need to return it and cancel lease since I bought a new 3a with unlocked bootloader.
Is the data recoverable? If so, can I make a pin and do another factory reset and would that be sufficient for privacy? I have all my passwords on Roboform.

If you removed your Google account before resetting you're safe. If you did not then log back in, delete your account from the device and factory reset again. I doubt anyone really cares if you are returning it to a carrier. If you are sending it back to a third party I'd be a little more careful.

The dirty trick is to remove your account, leave password on it, the reset from recovery. That will trigger a full wipe.

There used to be a way to force a pin on startup before boot. Is that option gone? Haven't used it in years since it was such a pain.

I am not sure anything changed, encrypting partitions have always been the best - and only real - way of protecting your device. The PINs etc. are eye candy.

You put on a pin, use the fingerprint scanner for bank accounts, good passwords, what else can you do? A thief will go for the person that has none of these, there are many devices for them to choose from.
If you are that concerned then keep the information off the device. No one wants your stuff as much as you think they do. If I have to encrypt my phone I might as well leave it home or use a pen and paper.

Our needs and concerns are obviously different. I think it is clear that encryption is recommended by knowledgeable people.
