[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] strictlyphat:
Different story for me. Unlocl works quick and very high success rate. Now with the glove requirement at work, I can unlock with nitrile gloves on(no powder tho), my iPhone wouldn't unlock thru face id due to also wearing a mask. Makes my day a BIT easier.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] yrp888:
That's impressive that it can recognise your print through the nitrile glove!
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] DoKaTSuYa:
Thanks, very helpful, just press the sensor quickly, it works so much faster!
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] strictlyphat:
Agreed. I was so happy.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] Geekser:
Glad I could help you - it seems so basic - but yet, I think we intuitively press and hold thinking that is the way we need to use the Unlock --- but a light touch is all it needs and it ultimately lives up to the challenge that we all hoped for when the Fingerprint Sensor was placed underr the screen.
[Samsung Galaxy S20 / S20+ / S20 Ultra Questions & ] San Diego:
I have to say that I now have a S20+ (gave up the Ultra) and now, with the 2nd firmware release (ATCT) the fingerprint sensor does really really well. I do also use whitestone dome glass screen protector, and I've trained my main finger (R thumb) into two slots of 4 to give even greater response. the other two are R index and L thumb, but I suppose you could use all 4 slots on just one digit, and it'd likely be even better.

Good luck!
[Samsung Galaxy Tab S4 Questions & Answers] galefabio:
Hello,

I need help, I uploaded the upload of an old version of TWRP to the tablet, but starting it doesn't allow me to do anything.

Get stuck on the home screen "Samsung galaxy tab s4"

It doesn't even allow me to go into download mode.

Error: "Set Warranty bit Recovery"

How can I do?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
First of all thanks in advance for any assistance you can provide me.

A while back I installed Alex.v52.ATT.162.Cube.ROM located at http://xdaforums.com/showthread.php?t=363865 and all was working as expected. I decided to install Duttys_WM6.1_5.2.19700_Hybrid_V2_1_64.08.21_CubeV2_ ROM located at http://xdaforums.com/showthread.php?t=388947 but upon completion all I got was the boot screen. Rebooting did not help so I reinstalled the Alex rom. Upon completion of the installation process of the Alex rom, the phone tried to reboot but nothing happened. It just stayed off. I tried to hard reset and nothing. When connecting to the computer and the power adapter, the charging light does not come on. I tried to change the battery and nothing helps. At this point I am out of things to try so I am posting in hopes someone has had this issue and was able to recover the phone.

Please note that I created a separate thread for this since the Alex rom thread was discontinue and Dutty is no longer supporting the Kaiser.

Thanks!!!!

[edit] sorry, my advice wount deffently not help you here. Just saw that I adviced on another issue.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] zeezee:
Did you at all revert from HardSPL? b/c i assume you had it at one time since you flashed alex's rom earlier.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] scotchua:
Can you get into the bootloader (hold down camera button when you reset with stylus?)
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] zeezee:
he can't get anything, not even power from the usb
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] scotchua:
Oh, i was confused by his statement about getting to the boot screen. Hmm, that's way over my head. You might try PM'ing Gsleon3, he is the man to fix that kind of stuff. Be nice to him though ;)
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] RizwanKhan:
OMG ... IS THIS TRUE?? could this really be? (i am feeling a nervous break down coming) ... please tell me this is a rumor.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] scotchua:
In case you're not joking. Dutty has moved onto the diamond. He posted a farewell thread.

[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] RizwanKhan:
thanks for the post skat's. Nah man i didn't know about that. I have been completely away from phone/internet for the past 2 weeks so didn't have any link to the cyber world. Just got back on yesterday and really hadn't have time to comb through everything i missed so far.

That is a bummer but i guess thats his to decide. I don't plan on getting a diamond but i hope he will cook for touch pro when that comes out.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
zeezee: The phone had HardSPL v1 and I did not do anything to update or change it.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
One thing I did notice when I removed the battery and used a friend's phone to test if it was working was that it was at 40% and I know that when installing a ROM it calls for the battery to over over 50%. Could this have caused the issue. I did charge it to 100% afterwards and put it back on the phone with no success.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] scotchua:
yeah, it is kind of a bummer, but i understand leaving for a new device. he spent a lot of time cooking here.

I'm definitely hitting up the touch pro. it looks fantastic. i will miss the tilting keyboard, but it looks so much better.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] zeezee:
ah..ouch this might be a tough one :(
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] JNasty:
Try this

I've had a similar problem when my device wouldn't power on:

Try holding down both soft keys and pressing the power button if that doesn't work

try holding down both soft keys and pressing the camera button
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] warwolfx0:
Unplug the device, remove the battery, take a nap (longer the better), replace the battery, then try powering it again, i had the same thing happen to me when i tried to cooking a ROM, scared the crap out of me. Thought i bricked my phone. but it came back to life after the cycle. You have to make sure that all the juice is gone from the unit, just changing the battery may not have enough time to discharge it, also make sure that the sim door is close and there is no SD card installed, after i got it to turn on i had to flash my device with a SD card cause the USB didn't work.

Hope this helps.

Good Luck
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
No luck!

Thanks everyone for your input but none of the suggestions worked. I guess next step is to put it up on ebay for parts :(
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] camboy06:
Were in the same boat

Same thing happend to my phone after flashing duttys rom and im still trying out how to fix it
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
Camboy06 please do let me know if you find a solution. I only had my Kaiser for a month or so. This obviously hasn't happened to many folks so finding a solution wont be easy.

Thanks!
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] JNasty:
Try This

Holding the 2 soft keys and pressing the reset button. If not that try holding the camera button and pressing the reset button.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Macgyvec3:
Happened to me too last night. Similar anyway. I was using skype and charging my phone from the charger then it just stopped charging. I soft reset and it still didn't work. Hard reset and that didn't work. The USB port is dead. I'm going to try flashing from the SD card. Maybe that will flash I'm sure but we'll see if it fixes my problem.
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] Macgyvec3:
Figured it out. The pins were no long bent on my usb port on my tilt. I have to replace it. Anyone know where to buy one?
[Tilt, TyTN II, MDA Vario III Windows Mobile ROM De] donjgmz:
JNasty...I tried both those suggestions already with no success. Phone doesnt turn on or get any power at all.

CHANGED: You must flash the dm-verity.zip on ROM install to use the backup/restore feature of TWRP. It won't work if /data is encrypted. I jumped the gun when making this thread.
[Moto G7 Power Guides, News, & Discussion] arkansawdave74:
EDIT2: I had also flashed dm-verity on install so /data wasn't encrypted.
[Moto G7 Power Guides, News, & Discussion] Trusaint:
Which Dm Verity did you use which version??
[Moto G7 Power Guides, News, & Discussion] TaZeR369:
Does this mean even today with the latest versions of twrp and magisk you cant restore the backups made of an encrypted phone? I just got a new Moto G7 Power and got it setup with those two things and made a backup - havnt tried restoring yet. Does your solution of flashing the dm-verify.zip thing mean the phone will be unencryped then? Because I cant have that, I rather not have backups. What about the old "adb backup" type command line does that still work?
[Moto G7 Power Guides, News, & Discussion] flash713:
I've had my phone since the day they were available at metro and I can't and don't even try to backup or restore anything anymore. On roms it always has broken lockscreen where you cannot secure phone. Because of this I stay encrypted and setup my **** all over again when I change roms.
[Moto G7 Power Guides, News, & Discussion] TaZeR369:
I see, too bad it's a nice function to backup/restore I guess I'll just backup my important data individually and try not to mess up my Rom.

Me too. I haven't a bit of luck with encrypted stock restores. I was told it would work if you don't restore /data, but when I made a backup without /data, it failed to restore. I HAVE been able to restore unencrypted customs though. I only backed up system, data, and boot when I succeeded. It's been a while. I think you have to wait a long time for the 1st boot after the restore, as if it were rebuilding ART or something. Haven't had any luck stopping stock from encrypting either. I hate not messing up my ROM. Boring.....
[Moto G7 Power Guides, News, & Discussion] googleverifysux:
Perhaps I am missing a critical detail, but I just successfully restored my latest LOS(lineage-17.1-20200524-UNOFFICIAL-ocean) & older CRD(crDroidAndroid-10.0-20200405-ocean-v6.4) backups(*) using TWRP(twrp-installer-3.3.1-2-ocean).

SELinux is NOT enforced, but "Trust"(lulz) claims the phone is encrypted.

My methodology requires installing the same base f/w I used when originally installing the ROM(former newest RETAIL for CRD & newest RETUS for LOS), root, flash copy partitions zip, flash>factory reset>1st boot of the original ROM zip, enable debug, install TWRP, boot into TWRP, wipe all & restore backup(*).

I just restored successfully 2x's on my xt1955-5.

I loaded LOS 10 & 3rds from scratch, made all my settings tweaks & made Titanium b/u(JIC), made TWRP b/u(*) then restored my previous CRD daily install using steps above. Then I repeated the above steps(again) to go back to my new, fresh LOS. It is annoying to have to reload f/w, et al, but def easier than reloading & retweaking the OS & all 3rds from scratch... Titanium fails to restore most settings + other nits.

To restore a backup(*) of a ROM I am currently running, I just boot to TWRP, wipe all & restore.

*: To make the original TWRP backup, I will run it & it will fail. I open the log file and find the last file/folder that "error"ed, delete the offender & re-run backup(boot, data & system). It works for me, no DM-verity flash required.

As always, YMMV.

Edit: PS: The problems seem to be stemming from beta testing the new "Trust"(lulz) framework, on all 10 ROMs(?). Would be nice to get that ironed out. A new Recovery wouldn't hurt, either. AFAIK, these problems exist in OFR, too.

[General Questions and Answers] LGZACRO:
Hi everyone,

I have rooted my last few smartphones and was always happy with it. Now I got new Blackview BV9800 PRO and I want to root it with Magisk. but as the phone is new, there is lack of information on the internet, Anyway, I have found some information, but it is not complete and I believe You, smart guys, can help me to root my smartphone ;)

This is the information I got:

How to root it with Magisk :

Download your rom from : viewtopic.php?f=285&t=532354 (you can alternatively extract it with SP Flash Tool and WWR)

Download and install Magisk Manager on your phone : https://github.com/topjohnwu/Magisk/rel ... v7.5.0.apk

Patch the boot image with Magisk Manager

Unlock the bootloader. (Wipe the phone! )

Flash the patched boot image with SP Flash Tool or Fastboot. (ONLY the boot image)

Reinstall Magisk Manager

This is what I did and what happened:

I installed latest Magisk apk from official sources. I opened the app, clicked on "Install Magisk", then via this app I downloaded the zip file, then tried to installed it via Magisk but got an error "Unsupported/Unknown image format".

Any ideas what have I done wrong? Did I have to flash boot image from the ROM, and not the one Magisk downloaded? P.S., the smartphone is new, nothing more then I written above is done to it (no oem unlocking, no usb debugging, etc).

Hello

Yesterday during an update, by accident, my equipment, BV9800pro, performed a complete formatting, "Full Format + Dowload", it seems that Nvram has also been rewritten. it is possible to provide us with a solution or file with this data, specific to our equipment. i need a original nvram.bin, and nvram.data, in firmware from Blackview site this its not exist..

if someone wants to help me, I send them a private message with their email address
[General Questions and Answers] LGZACRO:
My phone is not rooted unfortunatelly, if I can help in anyway (if there is a way) I would pull out the files for You.

Do You know how to guaranteed root BV9800 Pro without running into problems?
[General Questions and Answers] ryddk:
who guarantees this?

rooting worked for me with that solution given to the PM. I wanted to install AOSP, but I found that the thermal image did not work anymore, there were some problems when previewing the video files from Facebook, and I gave up. from the mistake as I mentioned I format + dowload and delete all important partitions. nvram .bin si nvdata. Nothing works properly, TEE and Google Key are inactive, the thermal image fails, some applications are closed immediately. This is the experience with rooting and installing AOSP on the BV9800Pro
[General Questions and Answers] LGZACRO:
Oh man... Sounds bad... have You emailed blackview after sale support (via email, not forum)? No response from them?

And let's say I only root my BV9800Pro, will I be able to send You the files You need?
[General Questions and Answers] ryddk:
make total firmware dump and send the bakup , or nvram.bin nvdata.bin file,
[General Questions and Answers] LGZACRO:

[General Questions and Answers] james35888:
I just rooted BV9800 pro yesterday.

You don't need to SP flash tool or others, just need adb and fastboot.

Quick steps:

1. set OEM unlock to allow

2. connect phone to windows

3. use adb to check if connecting. command: adb devices

4. using adb to reboot to bootloader, command: adb reboot bootloader

5. And then the phone will enter fastboot mode ( you could see small string at left bottom corner)

6. use fastboot command to unlock bootloader. command: fastboot flashing unlock

7. If fastboot program is waiting, please check windows device manager, there should be an unknown device, let windows search driver automatically. it needs android interface driver.

8.Using volume up or down to agree unlock.

9. If agree, all data will be disappeared.

10. Install Magisk manger

11. Download stock ROM from blackview forum. it is zip file. Unzip it and copy boot-verified.img to phone.

12. patch boot.img by Magisk manger.

13. Copy patch image file to windows

14. use adb to reboot phone to fastboot mode

15. reflash boot image file. command: fastboot flash boot patched file name (normally, I would put patch image file in the same folder of fastboot)

16. reboot (fastboot reboot) and reinstall Magisk manager

There are many Magisk root steps instruction in internet. You could refer to other steps, they should be clear than mine. I prepared lots of drivers and application. Finally, I only used adb and fastboot to root this phone.
[General Questions and Answers] LGZACRO:
I rooted it exactly like You and it worked perfectly! Thanks for auch detailed rooting guide!

By the way guys, I think we Should open the request for TWRP for BV9800Pro. How do You think?
[General Questions and Answers] james35888:
After you unlocked bootloader, it changed to orange state, and it always shows "Your device has been unlocked and can't be trusted..Your device will boot in 5 seconds", it could be resolved by modified LK image.

Refer to

1. https://forum.hovatek.com/thread-31664.html

2. http://bbs.blackview.hk/viewtopic.php?f=286&t=532899 -- included modified LK image

Of course, you could reflash by fastboot, no need to use SP flash tool.

hi if u have back up on your phone could u provide for me link. I had some problems with my loudspeaker and i thought its from the root, or software and i did full format and download. and now it show some watermark and probably is because i l deleted NVRAM.

i download already official version but didn't help ... thank u upfront.
[General Questions and Answers] vinko2000:
Hi, I'm not rooted (yet) and my BV9800 PRO is having some issues with the loudspeaker, any media like YouTube or Spotify, play audio for a second or two and then just go mute, volume can be high but no audio at all, phone calls last longer but also go mute and have to go back to regular "ear-speaker" to keep listen to the other side. Are this the same problems you refer to? I can't remember if this happened after the OTA update tho. Thank you.
[General Questions and Answers] zlatkomas:
Hi, rooted and installed twrp successful. In the beginning i thought from that could be the problem for the loudspeaker.and i factory restarted, and the sound come back with full potential,but it was last few day that pleasure and it started again. And i decided to download full rom and format fully and hopefully the problem will be solved. But it didn't. First i thought its software bug, second i thought the speaker need replacement. And if i replaced it won't solved the problem. Today i just sorted my problem.

How(my way how it solved the problem) i had that months this problem with the loudspeaker and i ordered new loudspeaker but i couldn't be patient and wait it.

1. j need to open your phone until u get to the speaker check youtube video how to do it.

2. U need some soldering knowledge and equipment.

I just applied a tiny bit of little Lead Flux Cored Solder on speaker connectors and assembled it.

Probably it was bad connection between the loudspeaker and the mainboard. If it continues same problem i recommend soldering with wire and it would be permanently solved.

Just to remain u u don't need removed the speaker from the back case, if u do that u will need some supper glue to put it back.

Soon i will upload some pics and video what i did and i hopefully u will find my explanation useful and solved the problem with many of you have same problem like mine. And i hope someone could help and send me a their backup, On my phone still show with this watermark Google and TEE on right top corner of the screen with some Chinese red letters: which means probably unregistered google or something after my full format

Thanks u and good luck.

bv9800 watermak TEE and Google

I had some problems with my loudspeaker and i thought its from the root, or software and i did full format and download. and now on the right corner on display it shows watermarks with red letters TEE and google and after some Chinese letters. probably because I deleted the NVram, I tried everything what i found on internet but pointless nothing working, ex. changing IMEI, WIfe address, Bluetooth,format, reformat reset, i got my original Imei but it still i have those red watermarks.

Could u send me the backup from your device to try if i could remove this, or if u have some full backup or some advice?
