Hello everyone,
So I have an Venku Android 10 PX6 unit that I had installed Hal9k onto some time ago, and for months everything worked fine.
However, about a week ago, the device got stuck on the boot logo and does not actually boot up android.
I have removed the power to the unit, pressing the buttons while its unplugged to drain any residual power, but that has done nothing. it just goes back to the boot logo once again.
The backup camera does work, but aside from that nothing else does. I do have the OEM FW on a flash drive, and I have tried to access recovery mode to flash it, but holding reset down doesnt seem to get me there. When I press down RST, the button lights turn off, as does the screen, but the button lights never flash indicating that I can release. I've tried holding it down for 15+ seconds, but no matter what, once I release it, the button lights come on like normal and so does the HAL9K boot image. It then just stays there.
At this point, I am thinking that this is a hardware failure, but I wanted to see if anyone had another creative way to get into recovery or something else I can try to get into recovery or reflash without recovery mode. I have looked at other posts, but couldnt find one that yielded any results.
Thank you all in advance.
Perhaps read MTCD forums and the detailed recovery / OTG posts

I was running Cyanogen 6.1 on my HTC Dream fine, after that i decided for full downgrade. So i searched google for it and found the cyanogen wiki for doing it. I followed each step and after flashing DREAIMG.NBH to my phone, it restarted. And so it entered a boot loop. I took off the batery and then tried to enter recovery or the bootloader.When powering the phone normally, i see the T-Mobile logo, and after that, the screen turns black. Whenever i try Camera + Power, after the logo it goes to black screen. Home + Power points the same thing and so does back + power. Fastboot doesn't seem to work even though i have all drivers properly installed and the Android ADB Device shows under Device Manager.
I know i messed up because i didn't wipe before the downgrade. If there is any possibility to repair it? If so..what is to be done?
Thank you in advance!
My son's Vega had Vegacream installed and was working fine until this afternoon, when it wouldn't turn back on, I could only get the backlight to show for a few seconds, then just a black screen. I had to hold the power button for 5 secs to reset it, only to get the same backlight for a few seconds then black screen.
I've made sure I had all the correct drivers installed using AUDI, and I can get the tablet into nvflash recovery no problem and reflash roms. I've tried reflashing vegacream, no difference, just backlight then black screen again. I've also tried reflashing vega moddedstock and original stock 1.10, it says they've flashed correctly in the dos window, but they just show the green android logo for a few seconds, then black screen again, and I have to hold power for 5 seconds to shut it down, then it just boots to the android logo again etc etc etc.
I know there are loads of posts already about Vegas that won't boot, and I've read lots of them , but I can't seem to find a solution to my problem.
Any help and advice would be greatly appreciated, my son is badgering me every 5 minutes, is my tablet fixed yet Dad?!
Hi all,
I'm facing a curious issue with my Oneplus 5. I bought it back in July on launch day and though I have rooted and used custom ROMs on all my previous phones, I never got around to doing it on my OP5 (never felt the need, no availability of root early on etc)
I started facing a problem with my mic not registering in Google Assistant/Alexa and while on speakerphone, all while sound recording works fine in recorder apps.
Tried attempting to reset the cache from recovery,
1. On pressing vol down+power while turned off, I get nothing. No vibration or anything.
2. On trying to reboot to recovery by turning on advanced reboot, I'm greeted with the 1+ powered by android splash screen, followed by a black, blank screen. Have to long press power button to get the phone to boot again (takes quite long).
Could anyone help if they are aware of a similar issue, or any ideas to correct the problem? I'd be really grateful.
I'm on latest Oreo Stock update.

Downlod the zip , extract it connect the phone to pc with pressing volume up and then use the tool for flashing up .
So, I rooted and tried flashing the stock ROM (from Sammobile, same country, same exact model [SM-G950F], I already had the stock ROM and had never flashed anything else to the phone other than root, June security update, my phone had July's) to see if I could fix a problem that couldn't be fixed with any other method I had tried.
Everything in Odin seemed to go well, I got the PASS green box at the end. But then the phone couldn't go pass the Samsung logo when booting up. I left it quite a few minutes, before trying to boot into recovery mode and wiping data. Only to realize that I couldn't boot into recovery mode. In fact, I can't even turn the phone off. No combination of hardware keys works other than power button + bixby + vol down, to get into download mode. But that's of no use, because when I plug my phone into my PC (with the same cable and port I used before to root and flash the firmware into it) it is not recognized by Odin or the PC.
It just has the Samsung logo flashing slowly over and over because I can't turn the device off. By the time the battery dies out I'll most likely have the logo burnt into the display.
I also haven't been able to find any help online. Everyone's suggestion is “boot into recovery and wipe data”, but I can't do that.
Is my phone gone for good?
downloaded magisk, created the patched boot.img
fastboot unlocked
flashed patched boot img
fastboot reboot
device powered on, charging indicator light comes on.
vibratr motor spins for about 10 seconds, screen stays off, restarts and goes again.
tried pressing v+ and power, nothing. all other combos, v-/power, vol+/- and power, nothing.
anyone have any clue how to recover from this?
It also happened with me 2 weeks earlier, but with my tab 4 10, I think its beacause of dm verity (verified boot).
Hopefully you are lucky , but I was not at that time, no one helped me ?, I spent 1 week to come out from that but you can recover your tab with in few minutes.
Just go in your browser and type lmsa.
You will found a lenovo motorola smart assistant website there, just click on it and install that app.
Then open that app , click on rescue and feed your device credentials, it will automatically start downloading the firmware and after downloading, it will guide you to how to connect your device to pc correctly for flashing and then it will automatically restore your device to it's orignal state.
No hassle of installing drivers etc.
And you will have your device working again ?.
First boot will take upto 5 min so be patient.

Click to expand...
Click to collapse
Use the tool on the lenovo website: rescue_and_smart_assistant_v5.3.0.21_signed_setup.exe
You can restore your OTA
Have you tried this?

It's a year later... I'm having a similar issue. Were you ever able to resolve the screen problem?
