Help with broken lcd device - Android Q&A, Help & Troubleshooting

Hello,
recently my bluboo xtouch (android 5.0.1) got its display broken and so i cna't see anything on screen, so to get access again to it i wanted to use [email protected] but my device isn't recognized by adb.
the touch on the phone still works but i don't know how well, the phone is still working as it is receiving messages and phone call, i managed to get the phone connected to the same network of my pc.
Now, usb debugging should be on as i never turned it off (is there a way of testing if it is enabled?), the phone is set to PTP as windows recognize it as a camera and i can access the phone but only the folders called
DCIM and Pictures. Under device manager it shows up as a portable device. The problem is that it won't show up in adb, i tried a lot of solution but nothing worked (the adb_usb.ini is set to the right VID, i got the drivers for my phone installed, i got 2 version of adb (one sohuld be 32 another 36) one from a freshly new install of android studio and another that i think is the universal one).
IT DOES SHOW UP IF I PUT IT IN (VOL+)+(POWER) MODE
Now i have no clues of to get it working i thought that, if the problem is the PTP mode i would need screenshots of the ui so i can change the mode without seeing the real screen, but the rom that is used by my device
is not that popular.
Anyone has any idea on how to show it under adb devices?
Thanks in advance
NEWS
i managed to reach the "select type of connection" and i've tried charge mode (doesn't work), old for xp (it shows up as a cd rom), and now i'm trying with MTP but i got problem with drivers
NEWS II
i managed to connect the phone in mtp and to copy all the files i needed to the pc, but still i'd like to get [email protected] working, i can swap between connection mode (mtp, ptp, charge) and i can unlock the phone (cause it's fingerprint locked). My new problem is: how do i backup all of my contacts?

[Q] galaxy s4 slow to start charging and will not connect to computer

I have searched all the threads I can find and can't find an answer so please forgive me if this is a common problem.
To make a long story short I had to replace my LCD and then the digitizer stopped working. I did a factory reset which solved the problem but then when I tried to install my backup I messed everything up and nothing was working. I could no longer connect any computer to my phone using several different USB cables. All my google services were not working along with my proximity sensor and light sensor.
I was able to get a fenny rooted stock rom to install using Mobile Odin Pro and I seem to have most of everything working again except the USB port.
I was unable to connect to a computer or charge. After trying everything I could find online including factory resets, *#0808# settings, USB debugging mode, I broke down and ordered a new USB port which I installed into my phone and I am having the same problem with the new port installed.
When I plug my phone into the charger it does nothing however if I turn the screen off and wait about 3 to 5 minutes the LCD will light up and indicate that it is charging and then the phone takes a charge. If I use the phone while it is plugged in it will never indicate that it is charging, I have to power the screen off for several minutes. I have tried a second known good battery and I have the same issue. I have tried two separate factory chargers which both work fine on my wife's S4 and neither work properly with my phone.
When I plug it into my computer I do not get the normal message to select MTP or camera. using the settings recommended on *#0808# of USB of AP and USB Settings of MTP + ADB.
If I use *#0808# and select CP under the USB tab and then plug the phone into my computer I hear my computer instantly make the sound it usually makes when you plug a usb device in but nothing else happens. This same computer works fine with my wife's other Galaxy S4 and I have tried this on three separate computers with the same result so I don't think it is a computer or usb cable issue.
Is there a way that I somehow deleted drivers or a file on my phone that controls the USB port? I am unable to attach screenshots on this post for some reason so below is what my about phone screen shows. Is it possible I have the wrong kernel or radio installed that could be causing this issue?

I would really appreciate any help someone can give me. Thank you in advance. If anyone is local to Rhode Island and willing to help me out in person I would be willing to pay you for your time, I just want to get this to work as I use my phone for work and need to be able to transfer files to my computer.
Last night I changed the SD card and when I did I plugged it into my computer and it started to charge. After about 10 minutes the computer beeped and I was now able to access my files on both my phone and SD card but it was not showing as connected using Kies.
It worked off and on today but now when I plug it in device manager shows qualcomm CDMA technologies MSN with a yellow explanation point saying driver not installed. When I plug my wife's s4 into this computer it works fine. Is it possible my s4 is somehow showing up to my computer as a galaxy note? That is the phone that I find in Google when I search that qualcomm driver.

[Q] [Q ; HELP] IMMEDIATE HELP for USB Debugging Problem

I have an LG L7 II Dual P715, and I was in 4.4.2 before, now I downgraded to Jellybean so that I'll be able to root it [I GOT THE KDZ FILE OF THE JB FIRMWARE FOR MY DEVICE FROM THIS LINK http://lg-phone-firmware.com/index.php?id_mod=21 ]. When I connected my phone to my laptop running windows 7 32-bit without turning on the USB Debugging yet and keep it in MTP connection, my phone got recognized immediately by the laptop (because i already had the drivers installed even before), but whenever I turn on the USB Debugging, when i connect it to my laptop, it just charges and it doesn't automatically enter the USB Connection Type where in i supposedly have to choose whether to use MTP connection or LG Software connection etc. unless I manually go to that section in the settings of the phone.
I have downloaded the driver of my phone. I even downloaded a universal driver of LG yet I still get the problem.
so basically, the problem is I CAN'T CONNECT MY PHONE TO MY LAPTOP IF IT'S IN A USB DEBUGGING MODE. I opened the Device Manager and I can't seem to find any trace of my device when it is in USB debugging mode Except if It is TURNED OFF.
What do you think is the problem with this? Is it my LG phone or the computer who has the problem? When I was in kitkat, I never experienced such issue, but when I flashed it back to JB, I cant rid of this problem anymore, PLEASE HELP, I badly want to connect my phone to the laptop while the USB Debugging is turned on.

If all you need is to root your device then you don't need USB debugging. You just need to use copy Framaroot's apk to your device and install it, and that you can do in MTP mode as well.

Never had similar problems with the USB drivers nor needed LG's tools, so can't help you there.

[Q] Backup Phone, Enable USB Debug on Samsung Galaxy S3 that has a broken screen

Hi,
I was wondering if anyone can help with my poorly phone?
My phone broke a couple of days ago and the screen is black and digitizer has broken therefore I’m unable to use it. I don’t think there is any point trying to get the screen fixed but it will cost as much as a new phone would. But what I would like to do is backup the data on my phone.
I have not got USB Debugging enabled and when I connect my phone to the PC, the drivers are installed and I see my phone as a portable media device but there are no files or drives to display the phones data through windows explorer! Please help!?
After some research on the internet I have downloaded [email protected] and ADB.exe but the phone is not recognised (I believe this is because USB Debugging is not enabled).
I then did some further investigation and managed to book my phone under fastboot in recovery mode and selected ADB mode, this connects to my PC and new driver is installed but I am now not sure how I can use this mode to backup my device? And enable USB debugging so I can use my phone on [email protected]
Anyone able to help?
Thanks
Sir,
Please wait until mods will move this thread to the device specific forum for more relevant answers.
Stand by
Good luck

Same problem :crying:

LineageOS 14.1 - How to activate USB massstorage access?

Hi!
I have searched XDA forum and other forum concerning LineageOS. But I have not found a solution.
My latest experiments were with installation of the adb interface on windows. At first, this worked well and I got full massstorage access. The Galaxy and its both memories did show up in Windows Explorer (like in old ages).
At the next restart of Windows (Win 7 64-bit Pro) when I connected my phone, Windows immediately did install the samsung drivers again. And since that things got even worse: No even the MTP and PTP Mode did not work, so that the Smartphone does not show up at all in the Windows Explorer!
At F-Droid, I have found an app, called USB Mountr. I tried this, but without any effort.
In the device manager of Windows I can see an „Android Composite ADB Interface”. It tells, that the device would work OK.
Now I am stuck with this and I hope, someone will help me, to activate usb massstorage access.
BTW: I have flashed my Galaxy S2 with Heimdall, running on Ubuntu. Heimdall on Windows 7 did not work, because of libusb error -12.
Latest status:
I have uninstalled the app USB mountr and did reboot the phone. Now the USBconnector is only active for charging the battery. I even get no connection in PTP or MTP mode.
Then I have deactivated USB debug mode and ADB. did a reboot, reactivated ADB and USB debug etc. and did further reboot the phone but with no success.
USB connection is nearly dead and cannot have connect with LUBUNTU Laptop. On Win 7, I get the signal tone, which is typical for connecting an USB device. The GT.i9100 shows up in Explorer but cannot be connected. Device manager tells me, that it is an Android device and all would be OK.
As a work around I am using MyPhoneExplorer on Win-7 and KDEconnect for Ubuntu.
Please can anybody tell me, what I should do, to get back at least USB connection in MTP or PTP mode???
I have the exact same problem.
I did notice, that after first boot, there was a message (several times) the MTP daemon/service stopped working (Crashed ?)
Does anyone else encounter this ?
Did anyone else resolve this ?
(Currently I was only able to get/send files to the device via BT, which is slow, annoying,
and a lot of work moving files to their required places after transmitting over BT)
Quick Fix for stuck on boot
This probably isn't the right place but you said there weren't many solutions. If your phone randomly gets stuck on boot you need to Delete Everything including system, factory data reset, flash ROM again with ADB, go through setup. The reason it probably hanged is because you installed an old version of SuperSU Binary or because you flash OpenGapps before setting up phone.
Hope this works
P.S Sorry for the late reply

No touch, no otg, no adb, can i save my data?

I dropped my phone and touchscreen went dead. It still worked but wasn't registering touch input.
Bought a new screen and replaced it, screen works but still doesn't react in any way.
The otg adapter for some reason doesn't work although it works on my other phone.
Thinking the rom has a otg switch I booted into twrp hoping it would work but unfortunately not.
Did a pc format since i last used adb so even if debugging is enabled on the phone pc isn't authorized and adb devices returns back empty
Data recovery programs don't pick up the usb connection with the phone (also if i plug my phone into the pc it charges, it doesn't mount any storage and device manager doesn't show anything particular connected)
Any ideas if and how i can recover my data?
