[Android Q&A, Help & Troubleshooting] GuestD0775:
Hello and thank you for your help. I currently have a Samsung Galaxy J7 1st generation. The model number is SM-j727VPP.

I cannot root the phone, because no matter what I've tried the option for unlocking the bootloader will not work (I've tried every method) but the USB debugging option is available.

At some point I believed my phone had some kind of malware or rogue OS installed on it (since there is absolutely no security doing a hard installation (holding volume down, power, and home keys). Basically anybody who had access to my phone when I wasn't there could have installed some OS or malware using the download function since there is no security (i've heard the Galaxy S requires password or other validation to use hard reset/download functions.

At any rate, this is the phone I have and I want to root the phone with a custom OS to get rid of all the bloatware and use it as a Wifi phone (using a different phone as my primary phone).

So I've tried flashing with Odin, with no success and for a year now have been unable to root the phone and tried probably 10 times by now. The unlock bootloader does NOT appear in the developer options no matter what I do. Only the USB debugging options are available.

Also, if I try to do a system repair using the Samsung Verizon software repair tool it downloads the software, reboots the phone into download mode then has the following error: unsupport dev_type, and freezes at 83%.

If I hard reset the phone (holding volume up, home, and power keys it has some kind of error and displays the following messages:

E: unknown volume for path [/vendor]

E: [libfs_mgr]Error loading verity table: invalid argument

E: unkown volume for path [/odm]

E: unkown volume for path [/vendor]

remove failed dir '/system/carrier/ATT/priv-app/AttIqi_ATT' (No such file or directory)

E: [libfs_mgr]Error fetching verity device number: No such device address

E:[libfs_mgr]Couldn't get verity device number!

E:[libfs_mgr]Error removing device mapping: No such device or address

So basically, what I'm asking help with is to either (a) please help me find a way to root this device and put a custom OS on it to get rid of the bloat ware and/or (b) help me use the Samsung repair tool and get rid of the unsupport dev_type as well as these errors when I hard reset the phone:

E: unknown volume for path [/vendor]

E: [libfs_mgr]Error loading verity table: invalid argument

E: unkown volume for path [/odm]

E: unkown volume for path [/vendor]

remove failed dir '/system/carrier/ATT/priv-app/AttIqi_ATT' (No such file or directory)

E: [libfs_mgr]Error fetching verity device number: No such device address

E:[libfs_mgr]Couldn't get verity device number!

E:[libfs_mgr]Error removing device mapping: No such device or address

Thank you. ANY information and advice would be greatly appreciated.

Hi there,

Just a quick question are you able to boot into the device, like the home screen.

[Android Q&A, Help & Troubleshooting] GuestD0775:
Yes. I can boot the device and get into Android. However there is an app running called LLK agent and a user certificate called com.samsung.android.dqagent_SA_SDK that autamatically keeps reinstalling itself. There is also an app called SVC agent and BBC agent. None of them can be removed.

[Google Pixel 3a XL Questions & Answers] h8Aramex:
I know, odd question, but it's important for me.

There is a Note 9 in the family, a OP7 Pro to try, and so on. They all suck at GPS tracking/lock-on compared to my old Note 4 and former Mate 10 Pro.

Notebookcheck praised the Pixel 3a XL's accuracy, so I wonder... is it really that good?

I mean, the OP7 Pro can't even get a lock in buildings, and Maps/Waze will remove your route/tracking altogether cause it has 0 confidence, and happens in a city as well.

Note 9 is the same, although the route stays, it just keeps throwing the car like streets away from the actual position.

Ps.: Moral of the story? Dual-band GPS is nothing more than just a buzzword.
[Google Pixel 3a XL Questions & Answers] poncespr:
For what it's worth, I've had the 3a XL since launch and only once while using Google maps has it lost GPS signal, and it was in a tunnel, so there was no clear sky.
[Google Pixel 3a XL Questions & Answers] h8Aramex:
Thank you! I know it sounds silly to even ask this, since some had luck with their phone purchases and GPS just worked... but on the other hand, I was extremely unlucky. And trust me, there is nothing worse than having no GPS.

I'll place an order and sell my phone / one of the phones.

Have a nice day!

[Samsung Galaxy S10e Questions & Answers] alexacm:
So I just bought a 970U1 global unlocked SD/S10e. In my ignorance, I thought the bootlaoder would be unlockable because it isn't tied to any US carrier and it is marketed as a "global unlocked device".

I am wondering if it is possible to flash firmware for the 9700 to the 970U1?

Then the next question would be.

If no, why not? The hardware appears to be identical, all the way down to dual sim capability.

If yes, would it work with CDMA US carriers, specifically Verizon? As the 9700 does not appear to support CDMA.

If the 9700 does not support CDMA, would it be possible to flash the radio so it would?

thanks-
[OnePlus 5 Questions & Answers] panoramix.druida:
Hi,

I bought a oneplus 5 phone because I was told it was going to be easy to install Lineage OS. I have try to install Lineage OS 16 on it for 2 days without success.

The first issue i had was installing twrp. Most of the twrp available did not worked with my phone. After flashing them with fastboot and reboot to recovery I would end up with a black screen and the the blue led turn on.

However I did find two TWPRs that work:

- twrp-3.2.1-1-cheeseburger.img

- twrp-3.2.3-0-20180822-codeworkx-cheeseburger.img

There might be other that would work, but this are the ones that I have tested.

After being able to boot to TWRP I try to flash the firmware 9.06 with success. Without reboot I flash lineage without success. I try to reboot and the system did not worked and I never reboot.

After a while I found a OxygenOS 4.5.10 that I hope is the stock rom. I has the following sha256sum: 7a8268f6a133f090a2d304aad2f92393aefbd4df34a6c2ed088909aaf7ccc2dd

That did worked and give me a breath. At least I had a working phone now. However I try to update and it did not worked.

From there I have been strugling with this project to install Lineage OS in my new phone. I know there are guides out there, but most of them did not work or are outated. There ara also threads in this forums, but are to big to try to follow. So I start this one, hopefully you can help me.

It would be great if there is a step by step guide on how to run Lineage OS in this phone.

Best,

Panoramix Druida
[OnePlus 5 Questions & Answers] strongst:
Hello, seems that you did not follow the installation instructions within the official LineageOS thread https://xdaforums.com/oneplus-5/development/rom-lineageos-16-0-pie-oneplus-5-t3843064

Your issues are clearly missed or skipped steps.

Please follow the instructions there and if you get stuck, report back with detailed information :good:
[OnePlus 5 Questions & Answers] panoramix.druida:
Thanks a lot for your quick response. It do have an issue with that guide and it is with point 1:crying::crying:

I have OxygenOS 4.5.10 and it does not upgrade to OxygenOS 5.1.4. What happened, is that in my first attempts to get this thing working I brick the phone and loose the stock firmware. Then I found this rom that allow me to use the phone (OxygenOS 5.1.4)

OnePlus5Oxygen_23_OTA_015_all_1708252353_f05918.zip

sha256: 7a8268f6a133f090a2d304aad2f92393aefbd4df34a6c2ed088909aaf7ccc2dd

It make the phone usable, but not upgradable. I doubt is the original, but I found the link on the Oneplus forums. (I can not post links because I am too new here)

After that I search for a ROM that comes with 5.1.4 and was really happy, and try to flash. It did not work, it is like it tries to boot, but never finish booting. I wait at least for 10 minutes. This the file and the sha256 hash:

OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip

sha256 2bb2e21a43572ac4bd2e5d1d30a3fb7562ddec280df3d452d61f58a4a8135f14

So I guess my first step would to find a way to get Oneplus 5.1.4 working. When I first try to upgrade the phone, I upgrade it from OxygenOS and it worked, however then I mess things and brick the phone. I found the rom that allow the phone to work (4.5.10), but for some reason the upgrades do not.

Thank you very much for your time.
[OnePlus 5 Questions & Answers] strongst:
You need to clean flash oxygenOS 5.1.4, then take ota update to 9.0.7 so you have the latest firmware.

Clean flash means that you need to wipe system, data, cache and format internal storage too.

So please backup everything off your device at first!

Everything you need you find here on xda, like the roms https://xdaforums.com/oneplus-5/how-to/oneplus-5-mirrors-official-oxygen-os-t3628190
[OnePlus 5 Questions & Answers] panoramix.druida:
Thanks, I would try this when I have time later today.
[OnePlus 5 Questions & Answers] panoramix.druida:
Finally I had time to work on this. The rom for 5.1.4 is: OnePlus5Oxygen_23_OTA_037_all_1807181258_7b4b6.zip, that I already tried and never boots :(. With twrp it seems that the Rom is installed, with the stock recovery the installation never ends. I am going to try with other ROMS. Hopefully one of them would allow updates.

I am going to start with the newest 5.1.7, and if that does not work would keep going down.

Thanks again.
[OnePlus 5 Questions & Answers] panoramix.druida:
5.1.7 did not boot, however I have some progress. I installed 4.5.12, I was previously at 4.5.10, so my android setup security patch levels went from July 2017 to to September 2017. Small step forward.

I have have that hypothesis that it would work with 4.x.x versions and not with 5.x.x versions. Tomorrow I would try to flash the latest 4.x.x and the earliest 5.x.x to see when does this things stop working.
[OnePlus 5 Questions & Answers] panoramix.druida:
I did the tests and I can flash up to 4.5.15. I tried to flash 5.0 and that did not worked. It flashes correctly, but it never finish booting, I waited up to 10 minutes.

So there is something preventing the phone to use version 5.x.x Should I try upgrading the firmware? Other ideas?
[OnePlus 5 Questions & Answers] strongst:
Please give detailed steps what you did including file versions. Otherwise I cannot help further.

Every oxygenOS version has firmware built in, no need to update it seperately.

Follow this:

1 flash this recovery with fastboot like the first time https://drive.google.com/file/d/1UlTftbe6wooAs4Fp0cjwXlOKmfQHgdfL/view?usp=drivesdk

2 boot the new twrp recovery

3 flash magisk 18.1 to make twrp stick

4 FORMAT internal storage(not wipe only) and wipe system and data partition

5 transfer oxygenOS 5.1.4 to the phone and flash it

6 boot oxygenOS 5.1.4 and take ota update to tg and latest OxygenOS(9.0.7 actually.

7 now you're on the latest OxygenOS and firmware version

[Android Q&A, Help & Troubleshooting] febtober:
I have Samsung Galaxy Tab S2 that I attempted to root earlier today. I used Odin and CF auto root method. Everything appeared to go fine, until it restarted itself after it was done. When it booted back up, the WiFi was not working. When I turn it on, it is simply stuck on "Turning on...." and nothing happens.

Problem 2: When I connect the tablet to a computer via USB cable, it does not recognize it. I'll hear a chime, so it detects it, but it does not show up in the file explorer. The tablet is set for a MTP USB configuration.

I tried a factory reset, but that did nothing.

I'm not sure what to do now. I do have a micro SD card, so I'm able to move it back and forth from the tablet to my PC to install APKs and other files. I'd like to try flashing a custom ROM to see if that fixes it, but now I'm not rooted. I used the SD card to install a couple of the one click root apps, but they were either unsuccessful, or require an internet connection to use.

I don't know if it's possible to actually install a custom ROM on a device that doesn't have internet access and can't use a USB cable.

If anyone has suggestions as to either of my problems, I'd love to hear it, because as of now I can't do anything with my tablet.
[Android Q&A, Help & Troubleshooting] daphr:
You can try to:

wipe data/cache from recovery and reboot it again to see if the wifi error still exists, or you can flash it again.

You can get and use adb/fastboot, if you haven't already, and check if fastboot (execute fastboot devices in cmd) recognizes your device after the chime sound. If you're lucky and your device is displayed, you can flash it again. All the best!
[Android Q&A, Help & Troubleshooting] febtober:
Thanks. Executing "fastboot devices" returns an empty list, however "ADB devices" returns some sort of serial number with "offline" next to it.

edit: I've been running adb kill-server and adb-start server commands, followed by adb devices, and that will switch the device status from "offline" to "unauthorized". I'm not sure how to fix that. I navigated to my .android folder on my PC and deleted the adbkey file but that didn't help.
[Android Q&A, Help & Troubleshooting] daphr:
In developer settings Enable USB debugging, revoke current USB debug authorizations and allow your PC's fingerprint. You can also enable OEM unlock in case you plan to play with the bootloader and custom ROMs.

Next in cmd after plugging the device in, check if it gets detected: adb devices

If you get the list you've mentioned, execute: adb reboot bootloader

This should boot your device into the fastboot mode where you have full access to your phone, so be careful what you're doing.

If you need more info on fastboot and adb, check out the forums.

Good luck!
[Android Q&A, Help & Troubleshooting] febtober:
Unfortunately it's still showing the device as "unauthorized". I've toggled developer options and USB debugging on and, and repeatedly tried "Revoke USB debugging authorizations" but it hasn't help. I can't execute the adb reboot bootloader command while it's unauthorized.
[Android Q&A, Help & Troubleshooting] daphr:
Have you been asked for a new computer ID to accept after revoking old ones and plugging the device in again?

As long as you don't add new fingerprint of your computer to the device, your device will be unauthorized.
[Android Q&A, Help & Troubleshooting] CosToDie:
You need to restock your tablet via odin (to put modem back aka Wifi)

After you restock Install Twrp and install magisk to root, instead of cf-root like you did (this will not breaking the safety net or knox even the modem)

(Note:before install magisk backup your "BOOT" via TWRP)

My data cable (usb port) also stoped working hence I changed my usb port, and its starts working but after a day problem revives again so I start charging from desktop/wall charger. Yesterday I test my data cable (usb) and found that its working. but I noticed that as soon I plug the usb cable the battery starts draining quicky (1% a minute) but after removing the data cable i softreset my cell and found that battery is still at its orignal level (before pluging the usb cable). Now I have also disabled the usb charging (registry hack) but all vain.

I dont know whats the actual problem I have also hardreset couple of times?

[Redmi K20 / Xiaomi Mi 9T Themes, Apps, and Mods] Scarface1991:
I stumbled on Reddit at this cool App that simulates a Notification LED using the actual screen. It was also featured on XDA and I decided to give it a try on the Mi9T. The App is called NotifyBuddy and is available for free on the Play Store.

My experience with it over a whole day was great. It actually looks like an LED lighting up. Since we have a Amoled screen it just uses a tiny part of the screen, so there is no huge battery drain. Also to prevent burn in it moves slightly in position every 5 to 10 minutes or so from left to right. You can have different colors for different Apps and how long the LED effect will be active until switching off. I have mine on for 5 minutes.

My major concern was battery life since when the App is active the phone probably doesn't go to deep sleep but after now 24 hours of the phone being unplugged I can say it's great. Just look at the Screenshots. I'm at 50% right now and almost 4,5 hours of SOT over 24 hours of usage. It works very well so far and if this doesn't get worse there is no reason to not keep it. Try it out guys if you are missing a Notification LED on the actual front of the phone.
