G925F boot loop / OTG & ADB not working HELP PLS?? - Galaxy S6 Edge Q&A, Help & Troubleshooting

Hi all,
I have a S6 Edge G925f, which is in need of some TLC.
It switches on into a boot loop, and has TWRP 3.0.2-0. It has no ROM.
I don't know if it has (or should have) anything else.
I have tried to send files via OTG and ADB, but both are failing, and I don't know why.
ADB (using fastboot) it spots the phone, gives the serial and recovery, but when I try to push a file, it waits... and waits.. and waits. Nothing happens. I have to pull the cable to force it to stop waiting.
OTG, I boot into TWRP and plug in a memory card with the ROM on, but it doesnt let me select OTG in the Install section. I tap it, but it work select.
I'm sure there is a really easy way to sort this out, but it is eluding me, and I'm hoping the community here can assist.
Any assistance would be much appreciated.
Thanks

[Q] Bootloop, USB Connectivity etc.

So, I have CyanogenMod 7.0.3 Stable flashed in my Legend, and it's been working just fine. Until couple days ago when I made some theme changes through Theme Chooser and flashed some theme add-ons. Now the phone is acting just stupidly. It's in a bootloop (sometimes loops in HTC bootscreen, sometimes in the CyanogenMod bootscreen), usb connectivity doesn't work (fastboot usb works, adb/mass storage etc. doesn't). I have tried to wipe the phone and flash that rom/recovery again through fastboot, but fastboot says "remote: not allowed" or something like that. Bootloader works, fastboot works, even recovery works but it's no use 'cause adb driver doesn't recognize the phone.
Please guys, help me. What should I do to get my phone running again? (working CyanogenMod or even a stock without root, I don't care, I just want this thing up and running again)
EDIT: And the weird thing is, that couple times I was able to boot the phone normally using recovery by just sticking the usb cable into the phone. And also, couple times I was able to boot it normally by just using fastboot reboot (I was able to get to the HTC Setup screen and then it would crash and show just black screen with notification bar)
It's possible the you're USB bricked. A quick search of "USB unbrick" should bring the required thread to light (search in development)

Yeah, I have thought of that! Only problem is that how am I supposed to get the required files (flash_image and .img) to SD card without a way to manage SD card? Can I flash the image using fastboot?
I can't do it inside the phone 'cause I'm in a bootloop and can't boot the phone.
EDIT: Is there a chance to do a wipe and flash a new rom using only fastboot or something?
In theory you can flash without recovery, but only if you're S-OFF. You'll need the ROM in .img format too.
I used a microSD to SDCard reader to transfer the files., they're fairly cheap in high street stores. Or borrow a friends Android phone

Well, am I able to flash those files once they are in the SD card? I mean with S-ON cause I don't have S-OFF?
Or is my phone a complete brick? =( Cause I'm pretty much all out of ideas..
Once you've got the files needed for a USB unbrick on your SD card you'll be fine
if you have recovery access did you try to make apply update from SD card in order to pass in cwm recovery.
if you got a USB brick you can use a multifonction printer to mount your SD on your computer.
So in a nutshell, my problems are:
- My Legend is in a bootloop
- Apparently my phone is USB bricked cause only fastboot works
- I don't have a recovery, when I go manually into recovery (recovery -> POWER + VOL UP) it goes into stock recovery
- And also my phone is S-ON
Could you guys point me into the right direction with this, I really want my phone back working. What should I do?
When you get to the stock recovery, navigate to ans select "flash update.zip from SDcard" That should get you to ClockworkMOD. Once there you'll need to use ADB to push the files required for the USB unbrick procedure to the SDcard (adb push [files-on-pc] /sdcard/) You should no be able to perform the the USB unbrick.
You may need your phone plugged into a PC for it to boot

But I'm getting this blue recovery screen with only four options instead of the original green one including option to flash zip. So wtf has happened?
EDIT: In the blue recovery screen it says Can't open cache/recovery/command. And when I choose "apply sdcard:update.zip" it says "signature verification failed" and it aborts the installation.
Fakeflash.

So I am able to flash roms only using this menu? Am I correct? Just do a wipe and apply update.zip?
Why does it say "verification failed" then?
EDIT: Oh I see, I have to download fake-flash update.zip and apply update.zip takes me to the clockwork recovery? When I put the update.zip to the SD card and apply it, then it should go on with out any "verification failed" errors?

My main priority is just to get the phone to run normally again, I can worry about the USB Unbrick later. So I just want to do a full wipe and flash Cyanogenmod again. Am I able to do all that is required to run the phone again normally with fakeflash?
Thanks in advance TheGrammarFreak, I really appreciate your help!
The phone won't run normally until you do a USB unbrick.
One of the things that happens with this USB brick is that a flag for advanced debugging gets set. It's a very deep setting, and the setting is read ad the HBOOT level. If this flag is set to on (like it is in a USB brick) the phone will not boot unless it's plugged into a computer. Remember that
In order to get your phone back I believe you will need to plug your phone into the PC and turn it on. It should boot, if not you will need to get to recovery and wipe/reflash (you'll need to do this while plugged into a PC too). Once you have a running system/you're in recovery you can use ADB to push the files needed for a USB unbrick to your SD card.
Assuming you got that far, you should be in a prime position to follow the USB unbrick procedure.
I'm going away tomorrow for a week, and I will not be online at all. If you need more help you will need to get someone else in. That said, I believe that with the information in this thread, the USB unbrick thread, the fakeflash thread and Google you have enough information and help top fix your phone

[Q] 10.1v stuck in boot loop

Hi all,
Looking for a little advice -- I've got a completely wiped (ie no data on the internal SD card) Galaxy Tab 10.1v that's stuck in a boot loop -- just continually cycles the first 'Galaxy Tab' logo again and again.
I'd ideally like to reset it to the stock Samsung 3.0.1 rom, but I can't get Odin to see the device.
I can happily get onto the Fastboot/Download mode screen, and Fastboot mode works fine (skitzandroid's recovery image from his rooting guide will let me get into basic recovery mode). However, switching to Download mode and checking with ADB for connected devices just yields a blank list -- ADB seemingly cannot find it, although it shows up in Windows Device Manager just fine.
I've confirmed ADB is working by plugging in my SGSII phone -- it's seen instantly.
I'm presuming that as ADB can't see the 10.1v, Odin can't either.
Does anyone have any advice on getting ADB to work?
Thanks!
------------------------------------------------------------------------------------
Scratch the above -- installed Kies and tried a bunch of different USB ports and that eventually fixed Odin's ability to detect the tablet. (It's worth noting that ADB still couldn't see it, however.)
Hope this helps anyone unfortunate enough to come across the same issue; I'm going to go clean the inside of my pants now.

Serious problem

Hi folks!
I've made some mistake and i dunno how to get out.
So today i was trying to flash CM9.
I didn't put the rom in the sdcard in first place cause i thought that would work in CWM. Now i've done everything like unlocking bootloader, install CWM and install CM kernel but...i'm stucked cause i have no way to access sdcard & push the zip file to install the ROM.
Mount options in CWM are not working and i'm not able to access adb to push the file.
What should i do?

Do you have fastboot?
Turn off phone, disconnect usb. Hold down Volume up and connect usb cable to pc. (dont touch power or home or something else, just keep volume up pressed). If you see a blue led and type in cmd: Fastboot devices. And a device pops op. You have fastboot and we can help further.
You could also try flashmode:
- Switch off the phone
- Press the Volume down button and hold it
- (While holding) Plug in the USB cable
-If successful, the LED should turn green
You could then flash a tft file from here using flashtool: http://www.mediafire.com/?tefi2sficc17a10
I have fastboot working of course!
I've flashed another kernel (official modded) and now i'm able to access sdcard!!!
I think that i've resolved :victory:

[Q] Stuck in whitescreen after boot / No ADB connection

Please HELP!
Yesterday I flashed my Odys Xelio (Allwinner A10) with CWM. After booting in a working state, I restarted in Recovery too full whipe and whipe dalvik, I installed gapps ans the compatibility.zip also from CWM.
After that I got stuck in a whitescreen. I can not access anything, not even CWM recovery anymore. In win 8 I only could see 1 to 2 undefined devices (should be a problem with the device AND a driver issue).
In Linux I could see a device in adb yesterday and could put it into "adb reboot recovery". Still whitescreen on the tablet, but I could push a recovery file with adb to the /sdcard/. Rebooting didn't bring me to another state.
Today I am not able to connect via adb. It always tells me "List of devices attached" and an empty list.
Display should be okay, no cable issue or sth. else. I really hope someone can help. Perhaps theres a way to JTAG the devices or there is a trick with pressing some buttons and using the USB cable...
BTW: While booting into CarbonRom the first time, the button-behaviour was strange or even totally not working. Perhaps that's a point?
THX in advance
EDIT: Now, after playing around with a needle into a "reset-hole" I finally found a way to see the device in adb. How do I go on!?

Huawei P20 Lite data recovery with a broken display (touch works, can unlock to get into phone, and fastboot works)

I'm in a bit of a pickle right here. My friend's P20 Lite got dropped and now the screen is dead. Backlight turns on, but the LCD is really, really broken. I can boot it up and unlock it using his swipe-code (by guessing where the dots are), but I cannot recover his data, because USB debugging is disabled
If I reboot into fastboot mode (Power + Vol Down), I can indeed see it on my PC as a fastboot device, but I can't use that for anything, as far as I know.
If I reboot into recovery mode (Power + Vol Up), adb doesn't work.
If I turn it on, unlock it, and plug in a Type-C to HDMI dongle (with power), it does not mirror the screen onto the display. I know the dongle works, as I've tested it with several devices.
HiSuite detects the device is in recovery mode, but then continues to say the device is not supported for system recovery.
What other options do I have? I can plug in a keyboard after it's unlocked, so maybe it's possible to navigate it that way? Like "press KEY to access settings, press down key 20 times, press enter to enter menu" etc. etc. Unfortunately I don't have a P20 spare laying around, so I can't use that for guidance.
The phone's bootloader is NOT unlocked, so I can't even flash TWRP and get into adb that way.
Hopefully someone can help!

Hi,
Cloud you maybe help me too? Because I have nearly the same problem. I have a Huawei P20 with a broken screen, the touch does not work and I have a password and therefore I cannot unlock it, I would like to be able to get all the data back from the phone and I have tried in many ways how to do it without being able to use it and the only solution is do it through a computer, I have already tried to activate usb debugging with a program, only it shows me the notification but I can not approve, I checked if there was active ADB but it says it is unauthorized and now I wonder if I should send the phone in recovery mode or fastboot mode so that I can control it from a pc or somehow receive the data, the question is how can I do? I have no idea how fastboot or recovery mode can be and whether it will make me lose everything or not so I would like to make sure by asking an expert, I would be very grateful if you could help me.
Hi.
Do anyone has a solution to this ? I'm in the exact same situation...
- normal mode no adb devices
- fastboot mode works, but... what to do in it ?
- recovery mode, no adb devices, nothing
- download Mode too, "adb devices" list it, but unauthorized... Maybe there is a way to copy a custom thing through SD ?
Need help please :'(

When is see on the internet what Download Mode is for, i imagine it's possible to copy a custom firmware/OS on the SD card, and then, install it automatically by this special mode.
I just want to retrieve my data... The only viable solution for the moment, is to buy a new P20 Lite screen and change it...
