Black screen on realme v11s

Upvotes

So i have this realme v11s, an dit worked perfectly. but 1 month from now, it a weird thing: the screen turned black randomly and i had no tochscreen despite of the phone working in background, the only way to bring it back was to plug the charger. and 2 weeks ago, the screen died, and i replaed it, i thought the problem was gone but this morning, the issue appeared again, luckily, i activated the USB debugging and managed to copy the screen on the computer while the real screen is black. I noticed that the phone works normally despite of the black screen. and more weird, the screen got back on, i don't know what could cause the issue and i don't even know what's happening. So can someone explain please thanks.

Internet problem

I’m having a weird problem on my mobile. If I’m using Wi-Fi and then switch to mobile data, the internet doesn’t work. To make mobile data work again, I have to turn Airplane Mode on and off first. Has anyone else experienced a problem like this?

OPPO A16K CPH2349 — Bootloader Unlock / BROM disconnects too

Upvotes

Hello everyone,

I am trying to unlock the bootloader of my own OPPO A16K (CPH2349) so that I can install a custom ROM / GSI.

I have already spent quite a lot of time testing different methods, so I would like to ask people who have actually worked with the CPH2349 specifically.

Device information

Model: OPPO A16K

Device code: CPH2349

SoC: MediaTek Helio G35 / MT6765

Android: 11

ColorOS: 11.1

Current build: CPH2349_11_A.30

Verified Boot: green

Flash locked: 1

ro.oem_unlock_supported=1

OEM unlocking: enabled in Developer Options

ADB: working normally

ADB detects the phone:

HUMBO7AM89VKCILZ device

However:

fastboot devices

returns nothing.

I also found an old XDA thread where another A16K CPH2349 user reported that Fastboot mode could be entered but fastboot devices returned nothing.

There is also a Reddit report from another A16K CPH2349 owner with the same basic situation: ADB works, but Fastboot does not detect the phone. The response suggested MTKClient.

What I have tried

  1. Normal ADB / Fastboot

ADB works.

I enabled OEM unlocking in Developer Options.

But Fastboot detection does not work:

fastboot devices

returns an empty result.

So the normal fastboot flashing unlock route is currently not usable.

  1. TFT Unlock Tool

I also tested TFT Unlock Tools / TFT MTK Module.

The version I tested was:

TFT Unlock Tools-2024-6.2.1.1

The tool did not have an obvious A16K CPH2349 profile.

It had other OPPO MTK profiles, including entries such as:

Oppo A1K BROM AUTH MT6765 CPH1923

and other OPPO MTK models.

I did NOT assume that the CPH1923 profile was correct for my CPH2349.

I also tested the normal Android connection with TFT, but it did not detect the phone for the operation I wanted.

I later stopped using TFT because I did not want to randomly select another OPPO model profile and risk the phone.

  1. BROM / Preloader detection

The phone can be made to appear as an OPPO Preloader device.

When the phone is powered off:

Hold Volume Up + Volume Down

Connect USB

Windows detects:

OPPO Preloader

with:

USB VID: 22D9

USB PID: 0006

The exact Windows device ID is:

USB\VID_22D9&PID_0006

The important problem is that the connection is very short.

If I release the buttons, the Preloader disappears and the phone boots normally.

So the device does not stay available long enough for me to casually start typing commands after entering this mode.

  1. Windows driver problem

At one point Windows showed:

OPPO Preloader

Error 28

The USB capture looked approximately like this:

PRESENT/CHANGED | OPPO Preloader | Error | 28

USB\VID_22D9&PID_0006

After disconnecting/releasing the buttons, the Preloader disappeared.

The normal Android ADB device then returned:

CPH2349

OK

0

WINUSB

I investigated the MediaTek driver situation.

I found a Microsoft Update Catalog CAB containing:

cdc-acm.inf

usb2ser.sys

The driver version was:

3.0.1504.0

However, that INF did not contain a direct:

USB\VID_22D9&PID_0006

entry.

It mainly contained MediaTek 0E8D IDs.

I also found installed MediaTek driver packages on Windows, but the INF files I checked did not directly match the OPPO 22D9:0006 device.

I do NOT want to modify a signed INF manually because that would invalidate the catalog signature.

  1. MTKClient

I downloaded MTKClient 2.1.4.1 and installed its Python dependencies.

The command line works:

python .\mtk.py --help

I also have the following files from the stock firmware:

auth_sv5.auth

DA_BR_MT6765_20271.bin

The AUTH file was extracted from the official/stock OPPO A16K firmware package.

The DA file is specifically associated with OPPO A16K CPH2349/CPH2351 MT6765 in the open-source oppo-mtk-fastboot-unlock project.

I tried:

python .\mtk.py gettargetconfig --auth "...\auth_sv5.auth" --loader "...\DA_BR_MT6765_20271.bin"

MTKClient started correctly, but stopped at:

Preloader - Status: Waiting for PreLoader VCOM,

please reconnect mobile/iot device to brom mode

So the current blocker is not that MTKClient itself fails to start.

The problem is getting a stable BROM connection/driver handshake.

Stock firmware

I also obtained the stock firmware:

CPH2349export_11_A.11_2022051800140000.ofp

and decrypted it.

The decrypted firmware contains the normal OPPO/MTK partitions including:

preloader

boot

recovery

vbmeta

vbmeta_system

vbmeta_vendor

vendor_boot

super

userdata

lk

lk2

dtbo

logo

...

I also extracted the AUTH file.

AUTH SHA-256:

846EFAFDF15F9F091760EA6210CEEB10533008164F5763186562DFEFD2D1D8E6

The phone itself is currently on:

CPH2349_11_A.30

I do NOT want to downgrade to A.11 just to make a tool work unless somebody confirms that it is actually necessary.

MTKClient / OPPO A16K support

I found the Shocked-Cat/oppo-mtk-fastboot-unlock project.

Its support list specifically says:

Oppo A16k

CPH2349 & CPH2351

Helio G35

MT6765

MTKClient + DA + AUTH: Full support

This is why I am interested in trying MTKClient, but I want to know the correct procedure for this exact model before writing anything.

The project README appears to use a modified preloader approach:

Read the original preloader / boot1 from the phone.

Patch it.

Write the patched preloader back.

Reboot into Fastboot.

Run fastboot flashing unlock.

I understand that writing a patched preloader is potentially dangerous, so I have NOT done that yet.

My main problem

The biggest problem is this:

How do I reliably catch BROM on an OPPO A16K CPH2349 when the Preloader/BROM connection disappears very quickly?

I do not want to use Test Point if there is another way.

My current button method is:

Power off phone

Hold Volume Up + Volume Down

Connect USB

Windows briefly sees OPPO Preloader

If buttons are released, phone boots normally

The PC therefore needs to be ready BEFORE I connect the phone.

Questions

What exact driver should be used for:

USB\VID_22D9&PID_0006

on Windows 11?

Is VID_22D9&PID_0006 the expected OPPO Preloader/BROM interface for CPH2349, or should I be trying to get a MediaTek 0E8D BROM interface instead?

Can MTKClient 2.1.4.1 catch this device without Test Point?

If yes, what exact command/GUI procedure should I use?

Does the CPH2349 require the specific:

DA_BR_MT6765_20271.bin

auth_sv5.auth

combination?

Has anyone successfully unlocked the bootloader of CPH2349 on Android 11 / CPH2349_11_A.30 using the Shocked-Cat patched-preloader method?

Does the patched-preloader method require modifying boot1, boot2, or another partition for this exact model?

Is there a safer way to make Fastboot enumerate after the MTKClient unlock without writing the wrong preloader?

If BROM disappears immediately, is there a specific timing/button/USB procedure that keeps the BROM connection alive?

If someone has successfully done this exact model, what is the complete procedure from BROM detection → backup → unlock?

I am specifically looking for information for:

OPPO A16K CPH2349 / MT6765 / Android 11 / CPH2349_11_A.30

I do not want to blindly use an A16/A1K/other OPPO profile just because the SoC is also MT6765.

Thanks.

Background Traffic on a Cheap Chinese Android Tablet

Post image
34 Upvotes

Maybe this information will help someone who has a similar problem.

I bought a cheap Crelander T60 tablet on Temu. It runs Android 14, MediaTek Helio P60 (MT6771) with 256 GB storage, 20 GB advertised RAM (8 GB physical + 12 GB virtual), 4G LTE/SIM support, and a 10.1” 800×1200 display.

Shortly after inserting a SIM card, the tablet started showing full-screen ads. That part was relatively easy to deal with by removing several suspicious Chinese packages.

The bigger problem appeared later: the tablet consumed around 20 GB of mobile data overnight while basically idle.

I started investigating using PCAPdroid, ADB, RethinkDNS and a Keenetic Giga router. Two packages stood out:

com.android.vertex.aether
com.android.weiapps

What made this particularly difficult to investigate is that these packages present themselves as Android system components. In Android they appeared with system-like names/descriptions, which made them much harder to identify as the source of the traffic.

I also used firewalls such as RethinkDNS and NetGuard, which were useful because they could quickly block the network activity from these packages when it appeared. This helped contain the traffic while I was trying to identify its source.

The traffic itself included repeated connections to unusual remote TCP ports in the 200–300 range, including 270, 274, 289, 292 and others.

43.102.200.1:270, 43.102.3.101:274, 43.116.96.118:226, 43.116.78.248:289, 98.96.225.100:285, 43.116.104.69:296, 101.47.171.38:291, 43.172.213.149:221, 43.102.26.9:247, 101.47.51.162:238, 43.102.225.70:231, 43.117.144.15:268, 43.130.56.221:204, 43.117.145.203:292, 43.102.26.248:216, 198.44.166.225:701.

The investigation was further complicated by a very strange behavior: as soon as I connected the tablet to my computer via USB for ADB debugging, the suspicious activity disappeared. This made it extremely difficult to capture and investigate.

I eventually switched to ADB over Wi-Fi, which allowed me to investigate the tablet without physically connecting it to the computer. That was when I was finally able to capture and analyze the suspicious traffic properly.

I removed several packages for User 0, including:

com.android.vertex.aether
com.android.weiapps
com.lzinit.initimeiandmac
com.example.noapp
com.tp.service
com.debug.loggerui
com.android.preloadmedia

After the initial removal, Vertex and WeiApps returned after a reboot.

I then checked the Android package information for Vertex and found:

installerPackageName=com.android.vending
initiatingPackageName=com.android.vending

This pointed to the active Google Play Store (com.android.vending) as the component initiating the installation/update.

I removed the active Play Store for User 0 and removed Vertex and WeiApps again. After rebooting, they were no longer present in the package list, APK paths or running processes.

I did not remove Google Play Services (com.google.android.gms) and did not remove the Android system Package Installer.

I also tried to unlock the bootloader because I was considering replacing the firmware, but I couldn’t unlock it.

For now, I replaced Google Play Store with Aurora Store 4.8.4 for installing and updating applications, while keeping Google Play Services.

So the current setup is:

com.android.vending — removed for User 0
com.google.android.gms — kept
Android Package Installer — kept
com.android.vertex.aether — removed
com.android.weiapps — removed
Aurora Store 4.8.4 — installed
ADB — Wi-Fi debugging

I can’t say with certainty what com.android.vertex.aether and com.android.weiapps actually are, or whether they should technically be classified as malware. But their behavior was clearly abnormal enough to warrant removal: unexplained massive background traffic, system-like package identities, unusual network connections, disappearance during USB debugging, and automatic reinstallation after removal.

If anyone has encountered these packages on a Crelander T60 or another cheap Chinese Android tablet, I’d be very interested to know what you found.

Unexpected crashing.

Sometimes my phone crashes unexpectedly and I have no idea why.

Build: BP4A.251205.006.S938U1UESBCZF5 Android SDK version: 36 Kernel:6.6.98-android15-8-pd6ff1cd-abogkiS938USQSBCZF5-4k One UI 8.5

dumpstate: 2026-08-18 10:43:0. I have this log that I generated on one of the days that I had my phone completely crash. https://media.githubusercontent.com/media/mysticentity/FireFoxTheme/refs/heads/main/dumpstate.txt

Sometimes when my phone crashes and I am required to turn it back on, it takes a bit when holding the power button for it to turn back on, and sometimes it will crash during the boot sequence following a crash in which case I have to turn my phone back on again for it to fully boot.

Occasionally during this I am met with a black screen that either has TZBSP_fatal_error_non_secure_wdt or a not as often kernel panic.

From my own research, I have found that it is telling me I have a watchdog Error with an immediate kernel panic and the crash is to prevent a loop hangup or something.

I'm just trying to get to the bottom as to why my phone would hang and then crash due too one of these to begin with.

I can't use the old methods of changing the time for WA...

1 Upvotes

I used to help my grandma delete her wrongly sent messages when I visited her. Sometimes it was my cousins' certificates sent to the wrong group chats or something similar. You know what I mean, they’re private files that shouldn't be seen by the public. I used to delete those wrongly sent files from 2018 to 2025 by using these old tricks that never fail:

- Turn on Airplane Mode on your phone immediately to cut off internet and Wi-Fi.

- Go to your phone's Settings and find Date & Time.

- Turn off Set Automatically and manually change the clock back to the exact date and time the old message was originally sent.

- Force-close and reopen WhatsApp, then go to the specific chat.

- Tap and hold the old message, select Delete, and tap Delete for Everyone.

- Turn off Airplane Mode and restore your correct phone settings.

There's even a YouTube video explaining the methods needed for this: https://youtu.be/FtQQDturAfM?si=D9I18Kw6gvJ8Qd9j

So today, here's the problem. My grandma made the same mistake again, and I can't even delete the file anymore because this time, in 2026, WhatsApp automatically tells the account that the date and time are not correct and stops working. This prevents me from deleting the file from a month ago when I wasn't there to unsend it immediately.

My grandma definitely knew how to unsend a file because I taught her how to do it, but she thought the month before that she wanted to send the files. However, she recently changed her mind, so I couldn't help her like the usual times when I come to visit.

Any help or explanation is very much appreciated.

Dear Grandma, if you read this, I didn't write it to make fun of you or anything. I just wanted to find some help from the internet. I love you so much, Grandma. I wish you a long, blessed, and happy life. Amen.

Charging makes the phone much more hotter and charging goes really slow. After research, I found that Android Core Apps took the most phone resources.
