My samsung galaxy s7 (SM-G930F) that was installing LineageOS 18.1 is stuck in a bootloop and I can not get into recovery or pretty much do anything. I can however get into download mode, but the phone is not recognized by USB connection. (From what I read online a year ago, this maybe a hardware issue with some samsung s7 phones. It has not worked for a while for me and I upgrade/update using the phone's hard drive or micro-SD card.) Is there a way to install/get in recovery without a USB connection (since the USB is not recognized). The USB connection does power the device so the issue is likely with the connection and data transfer part of the USB. I have tried other cables and computers and computer ports.
Can I flash a new recovery without USB? Is there any other option? Currently, the phone goes into boot (after the logo) and then keeps on the boot/install into lineage bubble from right to left and does not finish. I don't know if this means that the bootloader is corrupted.
I can get into "Download" mode, but because I can not connect by USB, I can not install a new recovery (unless there is some other option available).
I have/had a similar issue. To the best of my knowledge, you need the USB connector.
My USB port was broken because my meathead self somehow broke the contacts on the USB connector. I'd been using wireless charging to charge it in the meantime.
Replacing the usb connector through the back (soldering a new one on) isn't too bad a feat, and you don't have to mess with the notoriously fragile display at all. Here's a youtube video example

Hi,
Apologies if this has been asked before, but I did look at the suggested related threads and many other forums.
Ultimately, I am trying to root my son's Galaxy Tab 2 7" (wifi only) but I am falling at the first hurdle. When I plug the phone via USB to the laptop it claims the USB has malfunctioned and the device cannot be recognised, however, all my USB ports work perfectly. I have also installed the latest Samsung Drivers on the laptop (running Windows 8).
When I go to the Settings menu of the tab itself, there is NO USB connection settings at all, in any sub-menu and so I can't even check if it is set up to allow transfer. I have factory wiped in the hope that some updates removed this option, as I do recall (perhaps wrongly) that I was able to connect when we first purchased the device.
Is this a common issue with the Tab 2, or is it an issue with my set-up. If already known is there a solution, or is he doomed to walk stock for all eternity?
Any help would be greatly appreciated
If I'm not mistaken you actually want download mode, not usb, in order to flash a custom recovery via Odin. I think it's power plus vol down while plugging the phone to computer (phone is off).

I've had my OPO for a little over 7 months now. My issue began when I had my desktop at a friend's house and plugged my phone into a USB 3.0 port to grab some videos off the phone when the phone suddenly shut off and would not turn back on. I thought it was bricked somehow but after leaving it plugged into a USB 2.0 port for some time, the charging screen came on and I was able to turn the phone on, but since then both OTG and MTP/PTP transfer doesn't work. If/when the phone is plugged into a computer, it gives an error and Device Manager shows
"Port_#0001.Hub_#0004 Unknown USB Device (Port Reset Failed)" and I'm not only able to charge the phone with one out the dozens of micro usb cables I have. I've tried several cables and a handful of different computers and OSs (Windows 7,8,8.1,10, Ubuntu 15.04, Kali Linux) all to the same result.
I'm running COS 12.1-YOG4PAS3JL, rooted, and have TWRP installed. The phone doesn't show up when in Fastboot mode or the bootloader either. Nothing changes when I disable or enable USB Debugging as well. With DriveDroid if I set the USB system to "Standard Android" the phone reboots and that seems like the closest I've been able to get to any kind of progress. I've gone through unbricking threads as well as Googled until my fingers bled but I'm yet to find anyone with a similar situation where the phone isn't bricked, the micro usb port isn't broken, I can't pick between MTP or PTP mode (USB Connection just says USB is now disconnected), and I'm not running a custom ROM. I tried replacing the micro usb on the phone so I now know that it wasn't that that's been messed up but I'm not sure where to go from here. Any suggestions or help is greatly appreciated.
Hi,
Thank you for the forum (first post).
Trying to get the S6 recognised by pc:
When the phone is connected to the laptops usb port via micro usb and cable (usb debugging on, samsung usb drivers downloaded, mtp:usb on) the computer makes the 'plugged in' audio sound but there is no 'permission to transfer files via usb' type message.
It does charge.
Does this maybe mean the charging port is broken/damaged, or the usb is broken?
Only other detail is that I once got the computer to say in a pop up that it was labelled as a 'samsung s6' rather than unknown device, which it normally does. This any symptom maybe its just a software issue?
Trying to get my computer to connect to the phone and have tried most if not all software solutions so far (including factory reset) and now looking if its hardware. Any tips to get it connected welcome.
Thank you,
David

have you gone thru the usual suspects? (diff cable, usb port, diff computer altogether, blah blah blah)
Same happens here, it was fine after flashed Rom now it wont recognize it for some reason
Hi all,
A friend of my handed me his old Galaxy S6 with a broken screen. Like every typical user he had no cloud sync or back-up of his data. Normally I would tell them these lessons are hard-learned but in this case it's about important data and media of some projects in Africa he volunteered at some years ago.
This phone is a worst-case scenario. The screen is dead without backlight, the home button has been broken for some time and USB-Debugging is turned off. First thing I tried was connecting a USB-HDMI cable and OTG cable to see if we can unlock it with a conventional mouse, but sadly HDMI support was discontinued from the Galaxy S4. (Why!?)
I dismounted the phone and used an USB-Jig to force it into download mode. When connected to the computer both the MTP device and Samsung USB modem are visible. That tells me the phone still boots normally..
Connecting trough ADB did nothing, "no devices/emulators found". I also tried some commercial tools like FoneLab Android data recovery and some of the many (spyware-bundled) forks to no avail. Some detect the MTP device but off-couse need USB-Debugging to be enabled what seems to be impossible without a working screen.
Odin recognizes the phone but off course flashing the firmware will erase all data on the phone.
Replacement screens for this model are hard to get at and crazy expensive these days. Any other things I can try without risking data-loss?
Any tips are greatly appreciated!
Hi I am struggling to get data off my old galaxy S9, I have the 2 phones connected via USB but cannot authorise the old phone to transfer data, the screen is FUBAR and as such cannot press" allow" I think that presently the USB mode seems to be charging only, can anyone help? thanks
Use ABD and it comes with the the android SDK from google. But it requires a couple of your phones internal software switches to be set in order to access your phone via the USB interface. If you have not already set these switches before the screen got broken you may be out of luck.
