black screen asking for password to start device

Hey, all; Apologies, if this has been posted before, but I cannot seem to find this partilular issue. I had purchased my new T813, off a retailer on ebay, they indicated it was a store return, and had the google frp lock. I managed to easily bypass the frp in a Tab E, so I figured (quite incorrectly) that this would also be a no brainer... not so!
I have tried flashing several firmwares, (got one from Russia that seemed to work okay, but still had google frp. I put the earliest firmware I could find on it; "T813XXU1APD7_T813XAR1APD8_HOME.tar.md5" It failed, and I was stuck on download mode, and would only reset, using the Vol down/home/pwr buttons, only to reboot to a green screen, stating; "firmware update failed" (on the tablet, and the red failure in Odin). I could not get the flash to work, 4 times, and was worried about the tablet running out of battery, so I flashed (not knowing what the hell I was doing (how many readily admit that?) I flashed a 20mb file called; "BL_T813XXU2APK6_CL9829844_QB11715585_REV00_user_low_ship_MULTI_CERT.tar.md5" and the tablet was able to boot, past the Samsung flashscreen, but loaded up to a black screen stating; "enter password... to power on, or something like that" Does anyone know what the password is? I can't remember where I got this, there's so much scattered around the web, I was just reaching for anything... any help would be greatly appreciated.

Sounds like a stolen Tab, I'd say. ?

That's what I'd say also. Return to seller.

In order to bypass FRP, you have to downgrade the firmware to the lowest possible build as it doesn't have any patch to fix security holes.
Like mine, SM-P580, I had to flash Hong Kong firmware to bypass FRP as it's older build than US version. As long as you can downgrade firmware, bypass FRP is easy. I have done it within 3 minutes.
Power + Volume Down will force your tablet to restart. When you can get to Download Mode, try to flash a new an older firmware again, regardless region . If you can downgrade firmware, your chance is 100%. A build that forces you to have internet connection in order to continue until it get Google account verification is a build that need to downgrade. Older build allows to continue setup after Software Update check failure due to disconnected internet. The latest builds will lock attempt to downgrade so don't flash any new builds . I experiment with the latest build of Android 6 and Android 7, they do the same thing: check software revision and lock downgrade if a lower one is detected. I can downgrade Android 7 to Android 6 as long as that build has security patches which lock FRP bypass.
This users did it by downgrade from T813XXU2APK6 to T813XXU1APF4

Not necessary to be stolen. I bought mine without password or PIN, but forgot to remove the owner's Google account when flashing new firmware.
It activated FRP but I was able to bypass it to use the tablet.

First thing to do when buying second hand: factory data reset.
Everything else is stolen goods.

Excuse my ignorance sonhow do you activate trusted face. I have already set up "my face"

They've also removed the functionality in which you can navigate using the fingerprint sensor ?

After the may 2018 update I noticed some 4G connectivity issues: no more internet. By moments, the phone would switch to 3G and then internet would work.
I thought I did something bad, so I reset APNs, etc. no luck. I even completely wiped the phone, but that did not change anything.
Then I saw this thread on Nokia forum:
https://community.phones.nokia.com/support/discussions/topics/7000025066
For now, by forcing 3G, I can get internet all the time, but I hope this fix will be temporary.

ah sorry for a super late reply.. if u have already set up trusted face then it's already been activated.. just lock the screen and turn on using the power button.. there will be a small face icon at the bottom middle of the screen .. when it recognized ur face it will show a unlocked lock(open lock) icon.. then just swipe up the screen...

Hi, I can't update my phone to may security patch. I try to restore the phone but can not find the update. My phone is the TA-1062 variant with android one

Much easier with the roll back firmware and sideload using ADB or straight from recovery.
Done the ADB and got 8.1 April version (no wipe and everything seem to work fine).
After that got OTA update to May security patch.
More here: https://forum.xda-developers.com/showpost.php?p=76546067&postcount=56
It may be working without enrollment to developer preview. Someone uploaded the zip.

What's your location?

I was also stuck on 8.0, till I decided to go with manual method and update to 8.1 (I am in Ireland). I installed the 8.1 image with local method, no ADB needed. After that the updates were pulled without a problem.
If you want to follow the same procedure please find the topic "How to convert a Nokia 7+ from China Variant to Global" from the main Nokia 7 page and download "B2N-213B" which is 8.1. Ignore "B2N-3050", that is P preview which is very unstable. Place the file in the main directory of phone and dial the code provided in that thread. If you have the global variant there is no need to rename the file. To find the variant go to settings>about phone>build number. 00WW is the global while 00CN is the Chinese. (Thanks to hikari_calyx for making this possible).
It is likely that Nokia pulled the 8.1 updates off because of the stability issues on 8.1. The only issue I experienced after update was the NFC force close once. I enabled "show all force close in the background" from developer options, without that I wouldn't be notified, and after that I used NFC successfully, though the phone only recognizes my card near the camera! That is a terrible range for NFC, may cause serious issue for Android pay as payment devices have all sort of indentations on them. Anyone else had this issue?

Main directory is the same directory you open first when you connect your device for file transfer, that contains "alarms , android, data" directories. I put the file there without renaming it, and dialed the code. There are posts on the same thread that cover file not found issue, check them out. In any case if it doesn't find the file the only option is ADB sideload.

Face unlock was added

Scared about February security update

I bought MIA2 in January, global version and update it to pie without problems and then, aI installed the January security update, then I had a bootloop problem, and since it was untouched the only option was warranty or test point. Since I didn't want to lose some pictures, I opened my brand new device, :crying: did the test point, and put the V10.0.2 rom with MiFlash. It worked but I couldn't recover mi pictures.
Now, phone is offering me to install the February security update, and I'm scared to have the same issue again. I have USB debbuging activated and also the option for the OEM unlock activated. But haven't touched anything else.
Should I try to install this update?
Are these options enough to recover the phone if I have a problem or should I do test point again in case of bootloop?
Thanks for your answers!!

As of now we cannot unlock bootloader coz the update just messed with our device my laptop shows this device has malfunctiond failed to recognise...but it charges fine
If you unlock the bootloader you can install custom rom and do a bunch of cool tweeks in your phone totally worth it

ok, thnx... but I didn't have good experience with installing custom rom on my previous phones... there are always some bugs in the custom roms ... aren't there?
what should we do now, except waiting for new update?!!

This issue is not hugely addressed in the forum's they might not fix it in the next update (maybe)
There is nothing much we can do
the best part is that the phone charges! xd

Same here since May update, still waiting for a fix.

I experienced the same issu since April
Now i failled to update twrp then my phone is bricked

I'm guessing yours isn't (Android One) "jasmine" Global ROM? Because mine's got no such problem... Last screenshot is with the device ejected and unplugged, after having transferred these files.
EDIT:
Dumb question, but have you factory-data-reset it? "Erase all data (factory reset)" on this phone, under System, Reset options.

November 2019 update is now available

November 2019 security update is now available in India. Showing 93.9mb size for 4gb_64gb model.

Yes got in Malaysia also

also in iran but 88.4mb

Got it too(15=>17) 93,9 MB. Restart without any troubles.

Here in Brazil as well, everything went fine with magisk.

Got it here too. In the Netherlands. Size was about 93.6 MB.

I think that the biggest updates size are the ones that comes from version 15 (first October patch) and the smaller comes from version 16 (the last October patch)

Well bootloop as i expierienced and got it working agian.
1. ..remove simcard
2. Plug in charger. Wait till u see screen of battery power then power on ( phone will start then ).. or u do not see this screen during power on u will see bootloop. Then power off and repeat,took me 10-20 times power on/off but this worked for me 4 successful times (restarts)...sim i pushed in after the phone started and loaded android since then always charged and never turned off until the latest ota to 10.0.0.17!
So rom 10.0.0.15 creates bootloops.. now the phone updated via ota to 10.0.0.17... no bootloops expierienced any more...now i can sleep again
If u get the phone restarted u can see the rom version at about screen. U can update through ota this solved bootloop issue for me.
P.s. without battery charger connected and bootloop problems u will see phone turn off immediatly with some vibration or small buzz. In short u need to this with charger connected
Goodluck.

Updated from September to November. No issues.

What do you mean? Do i have to charge the phone while updating? Or do i have to charge the phone when the phone bootloops?

Manually installed it (by pressing myself check for updates) No new problems until now.

Yay more bugs!!
