Hi

I currently have a Samsung Galaxy Tab S3 aquired cheap from my employer (sm-t820) which has Samsung Retail mode installed, it is not a specially designed demo unit (ie. sm-t820x) but is proving impossible to return to factory.

I've successfully reset a few in the past by using the easily found passwords of 5444 and M729Q16K8546 as previous versions (like this one) have two apps that offer seperate settings, one has options to disable or customise Retail Mode, the other allows for removal (which forces a reset back to stock where retail mode is completely absent.)

Problem is the app that allows for removal keeps crashing on opening so I am unable to enter the passwords and run the reset. I have tried several workarounds including trying to set a password so I can enter it wrong 15 times (forcing a reset as a security measure) but the option to set one is missing (deliberatly removed) in settings, downloading apps from play that disable startup of services or do a reset in one click but they cannot get admin rights. Download mode is blocked so no Odin flashing is possible and attempting a reset through recovery mode is also blocked. I have also tried a few attempts at root so I can use busybox to reset but again no admin access.

The only solution I can think of is to get the retail mode app working again and the first thing would be to reinstall it. I have found a few versions out there, the most recent from Oct 18:

https://www.apkmirror.com/apk/samsu...etail-mode-9-3-20180905-android-apk-download/

It has options for country / channel etc but requires a password to begin the install (not the same one as for removal) which I can find no record of anywhere. If anyone happens to know it I would be grateful if you can post it here or anything else I can try.

Many Thanks...

[Samsung Galaxy S9  Questions & Answers] Jmack3d:
,

Hello everyone,

So I have (had) a Galaxy S9. A lady friends dog bit it (no b.s), and broke the screen touch input. Gradually the entire screen turned black. So now I have an S9 with no possibility of seeing or touching the screen.

The worst part is the screen broke WHILE IN maximum power save mode. Which means the USB can't be used for anything other than charging.

Making matters even worse, I had a 64gb SD card in it which had very important pictures and other valuable items.

I can't use the sd card on another phone because it says it has to be used on the original device (unmounted).

Does anyone have any ideas of what to do with getting my phone reset, get the info off, get the SD card data off etc.? I was quoted $300 for the repair.

I also have numerous, and I mean numerous, website/app logins using Google Authenticator. I can't access the Authenticator codes without the S9, and I also have A LOT of cryptocurrency wallet addresses on the Authenticator, and of course the key to access the Authenticator is on the SD card ?*♂️

Sorry but I never knew the SD card would be specific to a phone.. because if the phone breaks or is lost forever what do you do?

[Xiaomi Mi 9 Questions & Answers] rizzino:
Hi, I have this problem with the fingerprint reader under display of my xiaomi mi 9.

When it is resting on a surface I cannot unlock it with the fingerprint, I find this very annoying especially when I am at work and the phone is resting on the desk and I would like to unlock it, or when it is on the bedside table. The only way that allows me to unlock it with the sensor under the display is to take it in hand and unlock it.

I did several tests and I noticed that it is enough to touch the metal frame with a finger to allow the phone to unlock with the fingerprint reader. Alternatively, just have the USB cable inside the door.

If it is on a surface (for example a table or a desk) it does not allow me to record the imprint because it does not even detect the finger.

I don't understand if it is a thing wanted by xiaomi or it is a problem?

I leave below a video where I show what I said.

That is really weird
[Xiaomi Mi 9 Questions & Answers] Qidamin:
I have the same problem. It is quite weird that sometimes the fingerprint is working ok, sometimes it doesn't work at all, especially when on flat surface like in your example. I think it is working better for me now, after having erased and registered fingerprints again. Also, I feel that slightly "rolling" your finger on the fingerprint is working most of the time (for example put the left side of your fingerprint on the sensor then roll it to the right side, it should work better). I am on latest Xiaomi eu rom (9.5.1) and it seems a bit better too (or maybe I just get used to it!).
[Xiaomi Mi 9 Questions & Answers] Rversse:
My FP is good, doesn't have the problem like you said. On flat surface or anything, it's working. I'm using Xiaomi.EU Dev 9.5.1
[Xiaomi Mi 9 Questions & Answers] engineer000:
Try to add same finger multiple times like fingerprint 1, 2 3 and 4. That's what I did and it is now better.
[Xiaomi Mi 9 Questions & Answers] rizzino:
I'm on the last Global Beta (9.4.26) and before last EEA but the problem persist. I tried to record several times but without success. When the phone is resting on a surface it does not work. If it's in my hand it almost always works perfectly.

I can try to install the .eu and see if there are improvements.
[Xiaomi Mi 9 Questions & Answers] nitroax:
I have the same issue on lastest EEA update. When the phone is on flat surface, the sensor barely recognizes my finger input. Im pretty sure that was working fine before the last update.
[Xiaomi Mi 9 Questions & Answers] rizzino:
I hope this is a problem that can be solved via software with a future update. The point is that some have the same problem as me, while others work perfectly in any situation. So it is difficult to understand what is wrong.
[Xiaomi Mi 9 Questions & Answers] arddy1:
I have the same issue. It almost never work unlocking in flat surface. The only way is to press the sensor really hard with force, then it will unlock. I have similar case in redmi 3x, the screen dramatically lose sensitivity in flat surface. I dont know what causes. Maybe it is related to electrical grounding.

Yes Mi Forum is read-only since today, they want you to use Mi Community instead, but looks more like a Facebook group than a serious forum.

For me (latest 10.2.9 Global ROM), the fingerprint when flat on a surface works just fine; but as others said before, try re-adding your fingerprints using more different and wider angles; perhaps your finger was at 0 degree when you added the fingerprint whilst in real-life practice your finger is usually at 15 degrees. Making sure you cover all the sides of your finger helps (I have 5 fingerprints for 5 fingers registered, one was responding badly, so I readded that one and it works fine ever since).

But perhaps its indeed (latest( EEA ROM related ?
[Xiaomi Mi 9 Questions & Answers] Ataemonus:
Same issue with the latest Global Beta, sadly.
[Xiaomi Mi 9 Questions & Answers] Marcgyver675:
Hi. The problem is that seems like the fingerprint is disconnected. It doesn't react to any finger, it doesn't turn on. As soon as you pick up the phone it works flawlessly with any of the registered fingerprints.

[Xiaomi Mi 9 Questions & Answers] Ghon93:
I had the same problem on stock MIUI, with locked bootloader. Now I'm on Revolution OS and the problem seems solved, so I think it's a software issue.

Anyway when I had the problem, when the phone was on flat surfaces, I used to put my thumb on the bottom frame of the device, unlocking with the index (so using just one hand), and it worked perfectly. You can try this as a temporary workaround waiting for a software fix.
[Xiaomi Mi 9 Questions & Answers] SKiLLa XP:
Ok, that clarifies things; I thought it was conditionally unresponsive or inaccurate, but what you describe seems like the wakelocks are too aggressively set., very typical of MIUI.

Normally one would go Settings | Battery & Performance | Power Usage, and in the top-right hamburger-menu select 'Show System Apps' and select the Lock Screen or Fingerprint / Biometric services app and disable it's 'Power Restrictions' , but MIUI hides all most internal services.

Instead, download the MiAppa and click the 'Battery optimisation' tool; then in the blue title/dropdown bar select 'All Apps' instead of the default 'Not optmised' ... now a lot of internal services and components show up. Scroll down to 'MiuiBiometric' and changes it's 'optimize' setting to 'dont optimize'. That might help with it's wakelocks being filtered. I haven't tested the setting myself - and there are a lot of other system services that might be relevant to test - so please give it a good try.

Alternatively, run a custom ROM or enable the double-tap to wake (and/or pickup to wake, but I think you already had that active), so you tap to 'wake' it, and then the fingerprint does work instantly. Internally in 'deep sleep' state it might not respond to the fingerprint directly (i.e. after a few minutes idling with screen off), whilst screen-off idle before the deep-sleep state still works fine ...

Latest 10.2.24 EEA, zero problem.

Cue the "omg omg I have a bad phone how to fix plzzz"
[Xiaomi Mi 9 Questions & Answers] Marcgyver675:
Thanks. I've been trying what you said without success. Doesn't matter if the screen is on (on lock screen) or off. It seems like you need to be touching and holding the device with the hand.

What is surprising me is that if I am touching with a finger the frame of the phone in the usb port zone (the only part exposed as I am using a Nillkin cover) then seems to work the fingerprint sensor.

The problem only appeared since the last update so I am pointing to software error. I've reported to Xiaomi through the app.

[Xiaomi Mi 9 Questions & Answers] arddy1:
Have you tried unlocking with fingerprint in lockscreen (screen on)? Doesnt it different from the phone off? Mine is still same. When screen on, it should not be optimized.

Well, trick of unlocking with finger hold in side of phone seems help, but not much.

Plus add this trick, register your thumb 2 or 3 times, focus registering and unlocking in the center of thumb, not the tip. Dont use index finger. These combination of tricks really help for me unlocking in flat surface.
[Xiaomi Mi 9 Questions & Answers] bungalowbill:
Thank goodness this is not just me. I thought it was my fingers. I can concur that since the last update fingerprint recognition is horrendous when the device is laid flat but fine when held.
[Xiaomi Mi 9 Questions & Answers] Joad:
i had this problem . i think its fixed in latest global beta 9.5.9 . try it
[Xiaomi Mi 9 Questions & Answers] Ataemonus:
I have also another issue with the FP reader.

For instance, I registered both my thumbs, left and right.

Left unlocks in zero time, 99% of the time. Right does the same but only a few minutes after I register the fingerprint, then it's like my right thumb fingerprint changes. So I re-register it, works again for 1 hour tops, then back to the beginning.

So, unless my right thumb is shifting the fingerprint, there is something wrong.
[Xiaomi Mi 9 Questions & Answers] arddy1:
Yes its fixed in global 9.5.9. And the unlocking gets faster. Finally ?
[Xiaomi Mi 9 Questions & Answers] rizzino:
I confirm. It seems that the latest global beta update has fixed the problem. Great!

UPDATE: Unfortunately it's not as perfect as I hoped.

After a day on the phone switched on, the problem returned. But after a reboot it started working again (to unlock).

This has not changed:

I cannot register the fingerprint in the settings if the phone is placed on a surface. I can only register the fingerprint if the phone is held in the other hand or I touch the metal frame with a finger.
[Xiaomi Mi 9 Questions & Answers] rizzino:
I tested it a little more. If I turn on the screen first (with double tap or button) from the lockscreen with the fingerprint it does not unlock. If I try to unlock it with the fingerprint when the screen is off it works.

Here is the example video: https://youtu.be/Ve6eCVPhcY0

Fingerprint problem fixed

Delete you one or tow fingerprint and put your mobile phone on flat surface and add you fingerprint make sure not any other part of hand touching mobile body its take bit time to read fingerprint but one its done. You can use fingerprint on flat surface. 2nd option is when you want to unlock your mobile on flat surface or on mobile holder make sure when your finger on sensor your finger touching the mobile body this you get unlock you mobile phone whith delete you old fingerprint data

Hello friends.

I've received my Mi 9 yesterday, and guess what ? Same issue.

I can't even register one single part of my fingerprint when it's on a flat surface, no matter how hard i'm trying...

That's a very blocking problem...
[Xiaomi Mi 9 Questions & Answers] gerhard_wa:
Take the phone in the other hand or put it in your lap or put it on a non-flat surface. There must be a way for you to do this without having the phone on a flat surface.

[Xiaomi Mi 9 Questions & Answers] andrazek:
So, it seems like a hardware issue then. I have these problems too with my Mi9. Have you tried to return it?

In the past, I've experienced similar grounding problems with screen digitizer on Mi3 and Mi4c (not recognizing touch when on flat surface), that was very frustrating.
[Xiaomi Mi 9 Questions & Answers] Nate91:
Had the same problem. Like I did not press on the FP scanner. Sometimes there was a response if I pressed really hard. A minute ago, I updated to 10.2.14.0. PFAMIXM (released today I think), and the fingerprint scanner works like a charm, even when not in hand. It works faster, too.
[Xiaomi Mi 9 Questions & Answers] Terminator14:
Had same problem. Also just updated to 10.2.14.0 + rebooted an extra time. Fingerprint on flat surface got better and unlock feels in general faster.

Will try to delete fingerprints and make the new.

BTW digital wellbeing is also now included in that update ;)

With new fingerprints it works great.

Interesting enough, when it is lying on the table, it sometimes works best if the sceen is off and not showing the fingerprint on the screen.
[Xiaomi Mi 9 Questions & Answers] andrazek:
I have the latest xiaomi.eu rom (9.9.26) with MIUI 11 and no difference. This annoying fingerprint grounding issue still present. It cannot be fixed by software update imo, since the sensor doesn't even turn on when on flat surface (some surfaces are more problematic than others). The recognition success rate and speed is different thing and can be improved with the update.

[Moto G6 Questions & Answers] hydroman202:
I need assistance as the title says. First up my bootloader is not unlockable, (believe me I've tried) and here is my situation. I cannot flash the next OTA, because of failed error in recovery upon trying to install. There is no full firmware to reflash the device, only an OTA that I obtained (and yes it is completely for my phone model) (XT1925DL). I would sideload the OTA or apply it from sdcard in the recovery, however the device is not detected on Windows via adb or on linux, after hitting the sideload zip option, and Sdcard cannot mount. I get (sdcard failed to mount, E: installation aborted in recovery). If someone knows an option to maybe allow me to use the OTA file to repatch the system, without having to resort to the recovery mode, or adb sideload option, it would be appreciated if you could help.
[Moto G6 Questions & Answers] Ragarianok:
Is it a TracFone? You're probably going to have to flash in Fastboot.

Download the most recent firmware here:

https://mirrors.lolinet.com/firmware/moto/ali/official/TRAC/

And use this guide to flash:

https://xdaforums.com/moto-g6/how-to/guide-faster-updated-guide-to-root-t3914228
[Moto G6 Questions & Answers] hydroman202:
I appreciate the response. Unfortunately that site is not up to date with the TracFone firmware. The latest official one I have. And I can't flash it unfortunately because I'm on a newer firmware and it throws security downgrade errors when I try. If I could figure out how to get recovery mode to show up on my pc I would be ok.... Then I would be able to apply the OTA I need for the next one to complete successfully.
[Moto G6 Questions & Answers] Ragarianok:
Have you tried to run those Fastboot commands without:

[I]fastboot flash partition gpt.bin
fastboot flash bootloader bootloader.img[/I]

Should work if you exclude those two; that's what I did to downgrade from Pie back to Oreo.

You could also try Lenovo Moto Smart Assistant.
[Moto G6 Questions & Answers] Ragarianok:
I just realized that I totally misread your original post and, man, I feel like a total dummy.

Is the OTA currently on the root of your phone's internal storage?

If it's an actual update.zip file and it's in the root of your internal storage, you could try going into Settings/Apps & notifications/Apps info (tap the down arrow and select Show system)/Moto Update Services and make sure that Storage permission is toggled on. After that, try to perform an update.

I had a similar error when trying to sideload with ABD and update from SD in recovery, but it turned out that I was trying to update using full firmware.

Can you link the update file you have?
[Moto G6 Questions & Answers] hydroman202:
Unfortunately I cannot not link it but the file size of the ota is roughly 1.47 GB. And the ota was a upgrade to pie. I'm still on that one. Needing to reflash it so I can correct a partition issue. That's preventing the next ota from succeeding. The reason the next one doesn't succeed is because it checks the modem partition and it unfortunately fails to verify it because I accidentally flashed the wrong one. The ota should patch the modem in the device now I'm thinking because the modem that is currently on the device is the one before the ota arrived. All other partitions are the ones meant for the current firmware.
[Moto G6 Questions & Answers] Ragarianok:
Hm.

You could try to use the Lenovo Moto Smart Assistant. It has a Rescue option that returns the phone to stock firmware. It also has an Upgrade option; I've tried it but there aren't any updates for my phone. You could Rescuing and then Upgrading. Or you could Rescue and then try the OTA again.

The only downside is that everything on your phone's internal storage will be erased.

So, after using my phone at FHD+ for quite some time (without checking the resolution after update to 9.0) i changed my resolution to QHD and surprisingly phone started behaving better. As in it became much smoother and i gained performance in day to day apps even animations got better. Now i unterstand that this is not how it should go, or so i think, because to me it's not logical that it performs better by pushing bigger resolution.

[Android Q&A, Help & Troubleshooting] Tazerzero1:
I did the same exact thing, so far I've figured out that with that being the newest flash of combination we upgraded the bootloader to binary 3 now, the only firmware that will work is going to be the PVPU3ASC2 which is April's update but online you have to have membership or pay to download, unless that's all a scam? I just did this same wipe on a j327p and had no problem going up from binary 2 to 3 and flashing stock ROM. But from what I understand there's a way to just turn factory off in the combination ROM. I've spent hours pouring over different avenues to go. I was going to change device id to j337U being the unlocked version but I'm getting stuck on gaining SU permissions in the Shell with this new factory binary ROM. I can get adb shell while it's running and side load from recovery but nothing installs or flashes. I believe it's running a sort I emulated VM instead of running ON the phones persistent memory.

FINALLY someone to talk to about this specific problem. It was my fault flashing the U3 combo instead of the U2arj2 I should've.
