Bootloop after device got dipped in water -> Volume down button is messing around - Huawei P9 Lite 2017 (General)

Hey folks,
unfortunatly I am not able to boot my device properly since it fell into the bath tub. It boots into the download mode and stops after 5% saying Software install failed! That's because there is no .IMG on the SD Card I guess. Not sure what to do, I searched for a stock rom .IMG and put it on SDCARD/dload and got a good feeling that, maybe, it'll boot normally after installing this "update". So it boots into download mode and the update process is working just fine, but after the update successfully ends with 100% it reboots and starts the procedure over and over again.
I tried different button combinations to avoid booting the download modus - without success. I tried to get adb access by connecting it to the computer but just got an unauthorizised device - I never enabled usb debugging -.-
But then, somehow, it booted into safety mode and I was able to enable developer options and usb debugging. And I found the reason for the download mode bootloop. It turns out that the volume buttons are messed up. Volume up is not responding and volume down seems to be pressed all the time or repeatingly pressed in really short terms. Since my device is not rooted I installed an apk that allows me to disable the hardware buttons without root. But I found no way to run this app in safety mode. Also I have no access to the system files to change the key bindings on my own. I hoped to find a way to force normal boot out of safety mode but just got it booting up into the download mode again.
And there I am, my device is booting into download mode and nothing else. I don't know if it was just a lucky moment that the device booted into safety mode or if i did some magic that worked. But i can't get it to do something else than booting the download mode right now.
Do you have any idea what I can do without opening the device to unplug the buttons physically or to root it? If neccessary I am willing to do so but it's not the way I'd like to do.

[Q] Broken screen, trying to gain access to it

I have a S2 with a broken screen that had stock firmware installed (I don't remember which). I'm trying to gain access to the device to see if I can repurpose it for something else.
I tried following the guide here (http://forum.xda-developers.com/showthread.php?t=2786395)
I installed the adb/fastboot from here (http://forum.xda-developers.com/showthread.php?t=2786395)
I put the device in Download mode by pressing Vol UP/Vol DOWN and then plugging in the USB cable to a WinXP machine. On ODIN I can see COM6 light up, but if I run adb devices nothing shows up.
I think I'm missing a step somewhere. I think I need to get into recovery mode and not download mode, but I'm not able to do so without seeing the screen. I'm following what it says here (http://forum.xda-developers.com/showthread.php?t=1409769) but when trying to get into recovery mode it sounds like the phone just boots up instead.
Any suggestions? I think the goal is somehow enable usb debugging. I'm okay with losing the data on the device.

Samsung S7 can't boot into download mode

Ok, I bought a galaxy s7 from my friend, because he was getting a new phone, but I discovered that wifi wasn't working at all, so I thought it had to do something with the firmware and I decided to flash the rom with odin, with a newer version of the firmware.
This is where all my problems started, when I restarted my phone for the first time I noticed that the startup/booting animation was some weird ****, not like the usual one (the samsung logo) but was a weird loud animation with the letters of MTK, in that moment what came to my mind was that I just could be a custom rom or just a custom boot animation, so I didn't gave it too much attention, I continued to do what I was gonna do and tried to boot my phone into download mode with the classic normal method , Volum Down+Home+Power, when I tried this apparently It didn't work, I could stay there pressing the buttons for like 5 minutes and nothing would happen, and once I would release them, the phone would turn on and do the weird animation and boot like normal, at this point I was already worried so I proceded to Root my phone with KingRoot and install an app to manually boot my phone into download mode, it didn't worked. After hours of searching for a solution I found about ADB and I did all the steps to boot my phone from there, still nothing, when I typed the "abd reboot download mode" or something like that, the phone would just restart and do the ****ing weird animation again, so I tried booting into recovery mode and when I tried to do it, an android robot would appear laying on the ground with his chest open, and the words "No command". When I would press the home button the phone would react and send me to the recovery mode, normal.
So I'm begging you guys for help, since I don't know what to try now.
It looks like the download mode or maybe the firmware is broken, and I can barely do something without the download mode, pls help.
What I've tried so far:
-Basic 3 buttons method (can't remove battery, it's an s7)
- ADB method
- ADB fastboot method
- Vol Up+Vol Down+Home+Power
- Can't do anything with Odin since I need download mode
- Tried to install twrp recovery mode from ADB but says that It didn't found the file
If someone knows a solution for this please tell me what I can do. Sorry for bad english, right now I'm kinda exhausted because I've been trying over and over methods for like about 6+ hours
i had the same problem, phone is password pretected and cannou use factory reset and also phone wownt boot in download mode

No idea really but just to be sure. Did you try switching off phone completely and then trying 3 button combo for download mode?
Also post that **** boot animation logo as that might help us figure what you have flashed on phone.

Unbricking HTC U12+

Hey guys - I hope you're doing well.
I recently got an HTC U12+, but wanted to try using a custom ROM due to all of the bloatware . Unfortunately I think I've ended up bricking my device. Here are some things I've since tried:
- Restoring to the backup I made beforehand in TWRP - restore works without any errors, but then just hangs at the boot screen
- Method 1 from this thread (https://forum.xda-developers.com/u12-plus/how-to/collection-htcu-u12-ruu-firmware-t3794664) - TWRP always says the zip files are corrupted for some reason
- Method 3 from that same thread - this actually worked before, but I tried installing a custom ROM again, somehow messed up again, and now this method no longer works as it just hangs at the "HTC" boot screen for eternity
- Both methods in this thread (https://www.theandroidsoul.com/how-to-install-htc-firmware-ruu-and-zip/) - the first one leads to a "failed remote 99 ru unknown fail terrible mishap" error, and for some reason my PC doesn't see my phone when I try the second despite being able to see it in file manager
- Probably many other methods that I've now forgotten
I know this is a whole lot of information, but I'm in desperate need of some help. I typically like to troubleshoot things myself, but I've been trying to fix this for quite some time now and could definitely use another set of (much more experienced) eyes. I greatly appreciate any help you guys can provide.
Thanks.
Flash RUU with SD card method
Download RUU from here(important:check your CID): https://docs.google.com/spreadsheets/d/1wIRrVQawd5rD-t9VKPQ-SdRK20RcJVZhwD7lhmPIK8w/edit#gid=0
1. rename RUU to 2Q55IMG.zip
2. copy zip in the root of your sd card. - external card / not internal - it will not work
3. reboot to download mode,
4. your device will pick up the zip file and flash it.
5.follow on screen instructions and enjoy your RUU(this method erase all your data)
I'm having an issue with my u12+ where it just continually reboots to a message saying "The boot loader is unlocked and the software integrity cannot be guaranteed. Any data stored on the device maybe available to attackers, do not store sensitive data on this device" and then it shows the white HTC logo that says Powered by Android down the bottom of the screen, it stays like that for about 5 minutes and then reboots and does the same thing over again.
Holding the power down button does nothing, it will not turn off the phone. Holding power and volume down does nothing either. The phone just does this every 6 minutes and reboots and cycle and that's it.
I've tried putting the file 2Q55IMG_IMAGINE_DUGL_O80_SENSE10GP_hTC_Asia_TW_1.53.709.1_Radio_sdm845-000201b-1807311356_release_531499_signed_2_4.zip (renamed to 2Q55IMG.zip) on the root of a 8gb Fat32 formatted SD card, but I just can't get into recovery or download mode.
I've tried holding down all 3 side buttons for minutes, or just the power button, or combination of buttons, they all do nothing to the phone. (it's as tho they are disabled, but sometimes holding a combination of the 3 will make the phone vibrate a little bit, but in no particular time or order)
When the phone is in either state (locked bootloader message or white HTC logo) my Windows 10 PC sees the phone plugged in as a "USB Input Device", not an Android Phone or Android Device. So using ADB or Fastboot commands do not work to it. I've tried to force the driver to the HTC driver but that does not work.
I also tried using the RUU_IMAGINE_UHL_O80_SENSE10GP_NA_Gen_Unlock_1.30.617.2.exe file, but once again it doesn't detect my phone.
Any help would be kindly appreciated.
Cheers!
EDIT: So I was finally able to get into download mode by waiting until the phone done its 6 minute reboot and then holding power down until it vibrated once, then held volume up until it vibrated again, then let go of the power button, I was then able to choose recovery, download etc.
So I managed to get the file 2Q55IMG.zip to install, it said it installed 100% okay. The phone rebooted and now I'm stuck again just at the white HTC logo and Power by Android down the bottom of the screen.
This time the phone is not automatically rebooting itself and no key combinations will make it reboot. I've tried holding them all in certain combinations for periods of time, the phone will not reboot or turn off.
EDIT 2: So maybe I didn't wait long enough after installing the 2Q55IMG.zip file, I finally got the phone to reboot and now I've got a working phone again. happy days :laugh:

with the phone off, turn it on,when you feel first vibration
quick release power key and keep push volume down.
Smartphone should boot in bootloader mode.
can you get into this mode with this guide?

Cheer mates, issue sorted. I just updated my comment in my post.
Not sure if I'm game enough again now to try and put LeeDrOiD and Magisk on it.

Unable to boot, enter flash mode or enable USB debugging after 'succesful' flash

I use this forums a lot for info but in this case i can't find any leads of whee to go with this, so wondering if someone can chip in some ideas?
I flashed a ROM via flashtool but wasn't happy with it, so i thought i'd just go back to stock and so used flash tool AKA emma to flash one of the options given there.
First attempt to flash it said "flash failed" or something like that and had the "flashing failed, connect to computer" note in the phone when booting it. (I'm sort of making up the terms, not that much into the tech ). Anyway, i tried flashing the same FW again and this time it went through really quick being 'completed' in a few seconds.
Now when i try to boot it gets stuck in the 'Sony' logo. Can go into Fastboot but no Flash Mode (nothing happens using the vol down key), and USB debugging seems to be off now as well.
Emma only works in Flashmode so can't do anything with that. Flashtool doesn't offer anything useful in Fastboot and Xperia Companion recognises the phone when in Fastboot but asks that i unlock the screen and enter MTP...
Any help of where i can go with this?
Thanks
P.s. While keeping buttons pressed randomly it went once into flash mode, but trying to flash a ROM with flashtool it got stuck at "reding device data" and i haven't been able to enter the mode again. Is there an alternative key press combination that i stumbled on by chance? I think i just kept vol up and power held for a while and let go at a random number of phone vibrations
Just tried: Flashed twrp via fastboot and then rebooted into recovery. Same thing. It still opens to Sony splash screen and stays there
Ok, i'm kind of talking to myself here, but mild success and something that might help someone.
Managed to get back in flash mode. Don't know if it's a fluke, unique to this phone, or how it's actually meant to work, but the sequence is:
From the freezed up splash screen, and the USB connected, press and keep pressed power+vol up (hard restart/shutdown)
You get a single vibration, if you let go here it restarts. Keep pressing
You get a triple vibration, if you let go here it shuts down. Keep pressing
You get a single vibration, if you let go here it starts in fastboot. Keep pressing
You get a second single vibration, if you let go here it starts in flash mode.
Possibly a fluke but don't want to have to try again!
Anyway, i managed to flash the last working firmware and it's all good, yet this is the unwanted one. So issue is i still need to downgrade the phone to 7.1.1

Need help with my Google FRP locked [non-rooted] LGL455DL

I made the mistake of Factory Resetting my phone after a few failed attempts at remembering the Pattern to unlock the phone, in doing so I ended up being stuck in the set-up process because I forgot the Google account I was logged into on it before the Factory Reset, had been an account I just quickly made on the spot months ago just to set up an app on it. I'm posting here for help with this since I'm on day 4 of trying to find a way to bypass this and my head is ready to explode. I feel like someone with a fresh mind would be able to point me in the right direction.
If anyone can let me know if I'm doing something wrong or missing some steps that will help me try any one of these, or honestly any advice at all... I'd very much appreciate it and it'd help relieve a huge chunk of this ridiculous headache this has all been.
Thanks in advance!
What I've tried thus far --
- I know for most ways around this, USB debugging needs to be enabled. But since I cannot get past the initial set-up process, I can't access the settings to enable it.
- I also know that for a lot of Android devices USB debugging is enabled by default in Recovery Mode but everywhere I've searched for the hardware combination to boot into Recovery/Download mode, all say the same thing:
Turn phone off > Power up with Vol. Down + Power button until 'Download Mode' is displayed (for boot into Download mode, while holding Vol. Down + Power button plug OTG cable into device)
- My problem with this is that on my device, Vol. Down + Power button, restarts the phone. So instead of 'Download Mode', I'm just restarting the phone over and over again. I was able to get my phone to boot into was Safe mode using the Power button + Side button.
- I've also tried getting around this through a series of steps which involved the 'TalkBack' accessibility feature, but when I try toggling to enable it I just get a message saying "Complete setup first to continue"
From there --
I started looking up Stock ROMs that I'd be able to just flash the firmware. But for the life of me, I cannot seem to find anything for this device. And this is where I'm pretty much at now.
To remove FRP lock you boot into phone's Recovery mode and apply
1. Wipe data
2. Factory Reset
Every Android device gets shipped by default with Android Recovery.

I can't get my device to boot into Recovery mode. Everywhere I look up, it tells me to Power off device, then Press Vol. Down + Power key until the menu appears. But on my device, all that combination does is force the phone to restart.
