Black screen after installing rom

Hi, I want to install SVHD rom on my Desire S but when I finished the installer and my device reboots the HTC logo appears and after few seconds a black screen shows up.

Steps that I've taken:

Put the zip in my SD then I restarted in recovery twrp. I did factory reset - wipe cache - dalvik - system

I went to install selected the zip and opened it

A kind of installer appears, I did everything I supposed to do and when it was done it said reboot system

When I did that the HTC logo appears and after a few seconds there was a black screen.

I've seen it takes some time too boot up ~10min, I've wait more :(

Carbon ROM on the S4 mini Virgin Mobile (UK)??

Hi everyone,

I'm really eager to get this ROM onto my phone but don't want to risk bricking it in case it's not allowed on this specific type. My first choice has been Slim Bean, but for the S4 Mini I could only get an unofficial version and that apparently had terrible drain issues, so I chose Carbon but can't find very definitive information on it. Can anyone confirm whether I can do this? Or, which ROM is available for the S4 mini on Virgin Mobile UK?

[edit] I just thought I'd add that I have searched this forum for S4 Mini carbon, and I've searched google. And also should mention that I successfully rooted my phone earlier using arco68's guide. Also, when installing apps from Play website, my device shows up as T-Mobile, not Virgin?? No idea why, I have a Virgin contract.

Hello I'm tryin to change the startup sound delay on my phone. Ima total noob when it comes 2 android, but I'm KILLER good with computers. Can't program, I can do just about anything else with windows, tho, so I'm not that dumb. ANyway, since my phone is a pos, there's no custom rom for it, and since I rooted, I don't really see much need? I can tweak just about ANYTHING I want/need 2. Except, when my boot animation STARTS, there is no sound? SOund file (PowerOn.mp3, in /system/sounds/lgesounds, btw, not in bootanimation.zip) plays after about 200 frames of bootanim? I tried editing desc.txt, adding delay, up to 400 frames, no good. SInce my anim plays first, adding deadspace 2 my soundfile won't work. In init.rc, the following lines appear "# boot sound play before userdata mount for sync. with boot logo display, jinkyu.choi@lge.com

# start bootsound

# Backward compatibility

symlink /system/etc /etc

symlink /sys/kernel/debug /d " seems to say that my anim plays first? I got no references to bootsound or anything like it in build.props, either. I'm kinda @ a loss, not a programmer or an android expert. May sound trivial, but a silent tardis is a really woeful thing... :(

Hi,

I recently bought a Chinese knock off of a Mate 40 pro max, it has come with a modified version of Android that's truly aweful and slow (considering it has 12Gb of ram) I was looking to swap to any custom ROM that it will take.

If you could give a little guidance on what version I should install for this device that would be much appreciated.

[General Questions and Answers] Fytdyh:
Well, that's quite the unknown. There are many variables that you don't know, the state of the bootloader, if it supports rooting etc. You could simply try to open the bootloader without any code, if it doesn't work try reading the bootloader with dc unlocker (from 4€ to 15€). Since this is a fake, there is no guarantee that any of this will work. You might need to make a custom recovery yourself, since there isn't any for your phone. Also, custom roms made exactly for a fake like yours don't exist. Your best bet would be treble roms, see gsi github. If all this aren't working, you could patch the boot image with magisk and flash it with sp flash tool, since this phone seems to use mediatek.
[General Questions and Answers] Fytdyh:
This is not a pc based forum. Would recommend to search somewhere else. Second, you could just boot Linux from USB, might be a better option than booting Linux in a virtual box on top of windows. In 4 gigs of ram, you will encounter problems.
[General Questions and Answers] The_Confused_Shopper:
Hi,

I believe the bootloader can be unlocked through the Dev tools section of the settings (see image). If that's the case would you be able to point me in the right direction on what I should do and the guides to do it.

Thank you for your reply.
[General Questions and Answers] Fytdyh:
That's the first step. Next you would need to boot into fastboot mode and send the command to unlock the bootloader. That option in developer option only allows for its unlocking, doesn't unlocks it.

Ok I got LGUP to at least acknowledge my LGE LM-K500 (LMK500UM, LG K51). it gets as far as checking anti rollback before it errors out.

Device product name has changed.
TMO_US -> NAS_US

I can get firmware for TMO, VZW, METRO PCS. To my knowledge and I could be wrong I have never seen anything for any firmware on any device that is NAS. so unless I can find a firmware file for that product or I'm able to pull firmware from my product then I think it's dead in the water in terms of being able to root until a piece of firmware comes out. Any suggestions would be greatly appreciated.
[General Questions and Answers] DragonFire1024:
I found a few references to it but nothing that seemed dramatic enough for me to read far into. Never even knew there was a such thing as upload mode until I found this. I was hoping maybe it was a splash screen for fastboot but apparently it is not. So far I have yet to find any hopeful functionality in this mode. But that doesn't mean there isn't any.

On this same device I have managed to make KingRóot the device owner using ADB shell dpm. Kingroot does have a receiver for device owner. However it doesn't seem to have an effect that I can see. Hopefully something else might have a better effect at escalating privileges I don't know. was hoping this would be enough to get some kind of privilege escalation to get root access. Beforehand I was also able to make icebox apps freezer device owner as well. The good thing about that is the application can be used to legitimately disable or freeze every application including system apps.

Been reading around here but couldn't find any info on my specific device and from what I read a lot of the modding is device specific.

I have been gaming for 6 months and gotten interested in tech. I own a Lenovo tab e7 and wanted to try to root and overclock, game and maybe even mod the cooling system.

I searched for the device in Lenovo category but no option. I saw a video and someone done it but wanna know what XDA think.

If it's possible to root and OC my TB-7104F running Oreo Go ( 4x1.5ghz, 1gb ram) ?

[General Questions and Answers] Fytdyh:
Well, it's a simple process.backup your data since you will delete everything. Delete your Google account from your settings. Recommended would be to factory reset your device.

First you need to unlock the bootloader. Install on you computer "TOOL]Minimal ADB and Fastboot [2-9-18]". It's a zip, unzip it on your computer and you are done. Then, enter settings, about, press build until developer options appear. Then select "allow bootloader to be unlocked". Reboot into fastboot, read online how. Most likely will be something like power + volume down. Type "fastboot OEM unlock", hit enter, something might show on your tablet, choose the needed option and you are done, the bootloader is unlocked.

Root you can get either by using a one click app, like kingoroot (there are about 5-6 apps like this, search online) or to use the sp flash tool (your processor is mediatek). If you need to use the sp flash tool, you need to get the stock rom for your tablet and extract the boot.img. Install on your tablet magisk manager. Patch the boot.img with magisk, then flash it with the sp flash tool. That's how you get root.

For gaming, would recommend to install LSpeed(you can find it online, playstore remove it) and GL Tools (https://xdaforums.com/t/app-2-2-gltools-1-99xda-graphic-optimizer-updated-20-3-16.2828630/). Give them super su access.

Also, see if anyone made a twrp for your device. Really helps restoring it back to working order when you break something. Can't really recommend anything, since the twrp I found are on spooky websites. Take care.

Im at the stage of unlocking the bootloader. I have got the fastboot running via that program ABD and fastboot you recommended. once the fastboot opens on the device i try to type in command "fastboot OEM unlock" but it says <waiting for any device> and thats it. I also tried " fastboot flashing unlock " but no.

Have i done this right or do i need a unlock code from lenovo or is the bootloader locked and cant unlock?

Thanks so much for the easy to understand guide!!
[General Questions and Answers] Fytdyh:
Is your device in fastboot mode? Did you rebooted into fastboot mode? If not, that's the cause. Another cause for fastboot to not see your device is faulty fastboot drivers. You need to reinstall them.

The most safe way of making sure you ve got the right drivers would be to install lenovo link to both your pc and smartphone and connecting with it. If you manage to get it working correctly, this is ensure you ve got the best drivers. Afterwards, simply reboot the pc and uninstall the app from your pc and you can try unlocking your bootloader again.
[General Questions and Answers] SilvaGi:

[General Questions and Answers] Fytdyh:
Like I said, your issue is caused by the fact that your computer doesn't sees your device. Install lenovo link, on both, connect your smartphone to the pc, when that will happen means you ve got the right drivers fully installed and working. Then reboot, uninstall the pc app in order not to interfere with fastboot app and try unlocking it again.

[General Questions and Answers] SilvaGi:
I couldnt install lenovo link on PC only the lenovo tab, i think lenovo dont support it anymore, only app.

So i tried a zip file form a website and also successfully connect the tablet to pc via lenovos "rescue and smart assistant" program ( which should have drivers right?)

BUT when i try to unlock bootloader again i get same answers.

I connect the device, enter the cmds, i get to the some sort of fast boot, not sure if it is blackscreen on tablet, THEN I enter the cmd "fastboot OEM unlock but met with "waiting for any device"

How can i get drivers? i tried the drivers/ manuals downloads on website for my tablet but all there is is that rescue and smart assistance progeram and some open source code file .

Do you recon i dont have drivers still or maybe bootloader is untouchable??

Thanks mate
[General Questions and Answers] Fytdyh:
That may be. What you could try is the following : install magisk manager on your tablet, get the stock rom for your tablet, extract the boot.img, patched it with magisk manager and then flash it with sp flash tool. Some bootloaders, even when locked, do allow for such method. This way you gain root even with locked bootloader.

hi , i been trying to use sp flash tool to install a complete stock rom on my lenovo s5000. i have installed the vcom and preloader drivers , but every time i press the download button on the sp flash , it runs the installation until 50% , then it appears a error saying: 4008 install fail. i been trying on several versions of flash tool and it keep happening the same error. what can i do , i am stuck. help!!!!!!!
[General Questions and Answers] Fytdyh:
This error 4008 is generally caused when trying to flash a ROM or partition that isn't correctly addressed in the scatter. Either the scatter is addressing the image to flash at a spot that doesn't correspond with the partition setup, or the image is larger than what's specified in the scatter. Double check your scatter file. Most likely is faulty

How do I get my legally purchased google play apps to run on my amazon tablet? I have a fire 10 HD and I used the fire toolbox to debloat and install google play, and I was able to download my owned apps though google play onto my fire tablet, but some of them give a license error (mostly kemco titles) when I try to run them.

I'm going to stress that these are apps I purchased from the google play store and

legally own

, I'm not trying to pirate stuff. I can run them on my phone and through bluestacks on my PC just fine, but they fail the license check on my amazon tablet. I've tried rebooting the tablet and launching them through google play games but nothing works.
[General Questions and Answers] Fytdyh:
You ve bought the right to play those games under Google license agreement. Since Amazon fire tablets aren't under Google license agreement, you would need to buy them again under Amazon license agreement. Or try to speak with the developer, maybe you can get those apps on Amazon as well.
[General Questions and Answers] Waxfruit:
Other apps from the same developer work just fine though, and some of the ones that don't work aren't even sold on amazon. That's what confused me.

So basically some license checks look at the actual device too and not just whether or not the app has been purchased?

[General Questions and Answers] Fytdyh:
If the bootloader is tightly locked then it won't allow you to flash a patched boot image. But on some mediatek devices you can still flash a patched boot image, since the loose bootloader lock. You still can't flash a custom recovery or a custom rom.

The manufacturer sets the cpu voltage/clock speed in order to have the best ratio of battery life - performance. The difference between a computer and a smartphone, among others, is that on computer you have administrator rights. Rooting, on smartphone, gives you those rights. Out of the box you are not the administrator. Overclocking can damage your device if done incorrectly. That's why isn't available out of the box.

Hi,

I have a problem with my phone lock screen and I was pointed to this site. Hopefully some of you may be able to help me. I have a Sony Xperia ZX2 Compact which I unlock using either fingerprint or pattern. However, it all of the sudden asks me for a PIN which I do not remember setting. I have tried all possible PINs that I could think of. (And Im pretty sure that if I did set a PIN I would keep it the same as the default 0000). It does not prompt a "forgot your pin" google thing. It lets me try as many times as I want and just shows me the amount of times incorrectly entered my PIN.

I tried finding my phone using the google find my device app, but it cant find it. It is connected to the wifi and says it has internet, however I can no longer receive app messages (so it is probably not really connected to the internet).

Does anyone know how I can fix this without factory setting my phone and losing all my personal data?
