[HELP ASAP] Possibly soft-bricked phone, and flashmode won't work.

Hi there.

I'm using a Sony Xperia SP C5306. After attempting to install XperianZe OTA V3.0.5 (and Gapps), I find my phone stuck on the Sony Logo. It doesn't move. So, I do the sensible thing; I download a stock FTF (C5303_12.1.A.1.207_AU.ftf) and Flashtool, and attempt to install the stock ROM. But here's my problem; I can't get it to stay in Flashmode.

When plugging in my cable, I hold the VOL down button and the light goes green. Great! So the Flashtool starts flashing the FTF and my phone's green light goes out immediately. But it keeps flashing for a moment. And then the tool tells me suddenly that the phone has been disconnected. The phone goes to charge and sticks at the Sony logo again. This happens every single time.

TL;DR - My phone goes from flashmode straight to USB charge and I can't flash it to fix my softbrick.
If it's any help, my phone has a Locked Bootloader, and cannot be unlocked.

Help with possibly bricked SGH-T889 Samsung Galaxy Note 2

Long story short, I haven't done any of this stuff for a long time.
I did stuff here: .teamandroid.com/2016/03/08/update-tmobile-galaxy-note-2-t889-android-601-resurrection-remix-marshmallow-custom-rom/2/
I followed the instructions but I think where my hiccup happened was for whatever reason, CWM didn't install it's custom recovery system even though it said it had. So I'm stuck at 3e restore. However, in my stupidity and haste, I already wiped the data because I thought I was already in the CWM menu and didn't realize the 3e system would look so similar to the screen shots. Now I can't install the custom roms because they're not signatured, and I can't install a way to bypass the signature because that stuff is also not signatured. The only access I currently have to my phone is now through an ADB Sideload functionality using my PC.

Trying to at least get back to square one, or is there a way I can flash the CWM recovery system from this location?

Thanks for any help, not sure how to proceed from here (phone has no OS on it)

Phone not staying in flashmode (possibly just for a couple of seconds)

I managed to delete my system files (through TWRP). Thus I've been trying to flash my phone with the stock firmware (have been using the [Guide for NOOBS] for it), though after I connect the phone to enter flash mode (when flashtool asks for it) while holding the volume down button the green led turns on, flashtool doesn't says anything, and then the green led turns off, and then I see the Sony logo followed by TWRP.

I'm using the Xperia Flashing tool version 0.9.18.6 (by Androxyde), in the newer version I couldn't get it to 'see' the .ftf inside the app.
Quitting ADB nor using the 32bits instead of the 64bits version have helped.

Does anyone know a solution to this? :confused:

G930A FRM Bypass (Possibly other models as well)

This method requires a way to turn your Wifi on and off. I used a Mobile Hotspot from another phone for ease of use.

Begin by setting up the phone. Connect to Wifi when asked.

Agree to the terms and conditions. When it says "Checking Connection" (A few seconds after hitting Accept), disable your WiFi from the source (The hotspot, or unplug your router). If done at the right time, it will tell you 'Could not connect'. If it says anything else, back up, reconnect to WiFi, and try again. The timing isn't difficult. Hit next. Turn your WiFi Hotspot back on (The power), and make sure your phone reconnects automatically.

It should ask for date and time. Skip ahead until you get to the Privacy Policy screen with 3 check boxes (You have to scroll down to see them all). Click on the 'Privacy Policy' link. Scroll down to the block of text. Click and hold on any word. Click Share. CLICK AND HOLD on the button that pops up. Click Force Stop. Pull down the settings menu and scroll over to 'Ultra Power Saving Mode'. Turn it on. Select your language.

Click More, Click settings. WiFi will have been switched off; switch it back on from this menu. Back out and go to Internet. Go to https:// goo . gl/vzoLBx (Won't let me post links, so remove the spaces) and download the file (Quickshortcutmaker).

Exit the Internet. Click More. Click disable Ultra Power Saving. Click 'Emergency Call'. Dial 112. Wait for it to connect. Scroll to the right and select Internet. Search for 'Samsung Galaxy Apps'. Click the first link. Scroll down slightly, in the banner it will say 'Samsung galaxy Apps' and have an icon next to it. Click the icon. This will open the App. Search for 'Maxi Explorer'. Install it. This will require registering with Samsung, create an account if you don't have one.

Once installed, click the 'Play' icon next to Maxi Explorer. Find the file you downloaded (Should either be in 'Storage/Emulated/Download' or 'sdcard/download'). The file will be 'com.sika524.android.quickshortcut'. View, Settings, Turn Unknown Sources on, click OK, Click Open.

Once Opened, search for 'Google Account Manager' Click the drop down arrow next to it. Find the FIRST 'Type Email and Password', click on it. Click 'Try'. On the upper right, hit the 3 dots and select browser. Login with YOUR gmail account. Once you're back at the menu with 'Try', restart your phone.

From here, you should be able to go through the normal process without any issues. Hope this helped, I can provide more information or screenshots later.

Charging/Battery Problem, Possibly Hardware

I have an S3 I9305 with CM11 and a ZeroLemon 7200 battery. Have had no issues until last night, after years of use.

I have more than a few chargers, one of them always goes slowly. It's good for overnight charging and usually I can get more than a day out of a charge with this big charger.

Last night, though, I put it on to charge and after a little while I noticed that it was scorching hot. My battery monitor app read 131F. The charge percentage had gone down although it had been plugged in for a while.

When it had cooled, I tried plugged it in to a different charger and it failed to register that it was plugged in. The same is true for every charger I've tried. The only one that shows up in the OS is the one that caused the problem, and it immediately gets hot.

I have cleaned lint from the port and tried a stock battery. The issue remains. Also worth noting that when I plugged into a PC, it registers for five seconds and then behaves a though nothing is plugged in.

Finally, if I plug in the only charger that registers, with the phone powered off, it seems not to actually charge.

I've scoured these forums and I've found similar issues but none that seem quite like mine.

Is it a hardware problem? I recall that the phone took a bit of a fall yesterday.
