[Q] No ROM, can't adb sideload!

So I wiped my phone, went to flash the unofficial kitkat CM rom, and found out I had the wrong recovery version. No biggie, I thought, I'll just reflash my backup ROM. Well, it wasn't where I left it, so now I'm stuck without a ROM to flash. That was okay, though, I could just push one via adb. Then my computer gave me the "USB device not recognized" thing, and so I've tried reinstalling drivers, cleaning the registry, rebooting many times, and all to no avail. I'm lost! Wise ones of XDA, what can I do?

Bump. I really could use some help, I use my phone for work and school and it's a paperweight in it's current state.

I'm guessing you have no access to an sdcard? Looks like you need to use Odin to go back to stock then reroot and unlock. Try uninstalling the drivers then boot your S3 into download mode (hold volume down, home, and power) follow the on-screen prompt, then plug your S3 into the computer to force install new drivers. Now, unplug and pull the battery and try flashing stock, and root/unlock. Try another port, keep the computer plugged into the wall, and also make sure you're using the Samsung USB cable.

No sd card. My computer shows the same "USB device not recognized" message while the phone is in either download mode or recovery, and while using my samsung usb cable and a new one I bought yesterday evening. I've deleted every driver for it, tried every port, and it's the same thing every time. EXCEPT, for some reason, when I plug it into my USB 3.0 ports, it shows up in device manager under "other devices- unknown device", but when it's plugged into my USB 2.0 port, it shows up under "USB controllers- unknown USB device (invalid device descriptor)".

If its not connecting to your main computer, try another computer. Honestly though, I think you need to purchase a cheap sdcard (format it to Fat32) and put a rom on there. Cuz you can still access download mode and also recovery correct? Maybe by then, there will be a few more replies or some idea that will get you in the right direction.

I just have my laptop. I've bought an sd card now, but I don't have a reader. When I fix this I'll put a backup on there I think I'm just going to reinstall windows and get a fresh start. Then maybe I'll be able to ADB sideload a rom.

I had similar problem
After I screwed up my device, this was the way I got the right recovery installed in order to flash 4.4
I cant post links in posts yet, I'll pm you the link.

[Q] Flash Tools

So I purchased an Xperia Z3 on Amazon and when I received it it had italian firmware on it. I was planning on installing the stock rom with flashtools but was wondering if it was really just that easy. Are there any drawbacks to doing this? Should I just do it? Normally I wouldnt care but there are loads of carrier apps on it that I hate staring at when I'm flipping through the app drawer.

Easy mate loads of tutorials around but flashtool tells you step by step what to do anyway. Just flash a generic firmware for your model and problem solved. Only drawbacks are if you unlock the bootloader which you can't do accidently anyway. If you need to send your phone in for warranty purposes just put the Italian firmware back on it. Just make sure your battery has a decent charge before you do it

Thanks!!!! It seems so easy, I should've done it long ago.

Use debugging shouldn't matter in flashmode make sure the phone is.off and hold volume down while connecting the usb cable. Also make sure your drivers are installed

Have you actually tried to flash the FTF?
Jus go ahead and give it a try

Download ftf for your model, flash it with Flashtool. You only need drivers to be installed.
Good Luck.

Shouldn't one just need to install PC Companion?
http://support.sonymobile.com/gb/tools/pc-companion/
All USB drivers should be included. Since it seems you have it installed already try to uninstall it (and the USB drivers if they still are there), reboot and install PC Companion again.
Otherwise if you have access to a Mac make it simple and do it from there. No bleeding drivers needed.

As Miche1asso said, PC companion should do the work.
Also install falshmod and fastboot drivers from Flashtool/drivers folder, if you're on Windows 8.1 you need to disable driver signature verification (Google that).
Good Luck
Xperia M2 D2303 on K.K. 4.4.4

Don't worry OP. As you said, your phone's pattern is locked so even if you connect it to the pc it won't be recognised.
1. Install pc companion.
2. Search for the repair option. (Google it)
3. Then select your phone model. Go ahead.
4. Official firmware will be downloaded now.
5. Pc companion will then ask you to connect phone in flashmode by switching off phone and then holding volume down button and connecting to usb cable.
6. Leave it for 20 minutes.
7. Previous data will be gone. Enjoy fresh stock rom.
Don't worry about the drivers. When you connect phone in flashmode, your computer will install s1 boot drivers which will do the work.

Flashtools doesn't have drivers for Xperia M2.
Trick to install Xperia M2 drivers.
1. Remove Xperia M2 from devices and printers section. Reboot.
2. Install PC companion.
3. Click how to connect and select usb cable.
4. When PC companion asks to connect phone just connect and leave it.
5. It takes a little time but you can see a window saying installing drivers for Xperia M2.
6. After finishing all of this, you can check in flashtools whether drivers are fully installed or not.
If this helps, use it. ?

Try with this flashtool:
http://www.flashtool.net/index.php
Try connecting it in flashmode to install drivers (connect phone turned off to PC holding volume down button).

just the same problema
ihave do it but nothing .
download the adb driver installer to find my device but nothing no device founded
i try many times connect phone turned off to PC holding volume down button but cant in to flash mode . thnx for your time
i want suitable *.inf for manual driver install for wxp sp3 32bit

Do you have access to another computer? I'd try to see if it works on that. At least you would rule out the option that the phone USB is burned or something. And in case you didn't do it already, I'd try with a third USB cable.

You're making a mistake my friend.
Why am i sure? Because i did the same thing. Drivers will only be installed by pcc as far as i know. Flashtool doesn't have drivers for M2.
Follow my tutorial exactly the way I've given it.
Start fresh. A new pc running windows 7 will do the work.

thnks my friend but...
I have already done in Laptop with windows step by step your tutorial but nothing just same problema.
i dont have hardware proble with usb port because the battery is charging
i try original usb cable but nothing change
from pc companion console if this help

Technically that doesn't give 100% certainty that the USB is working. if one of the other pins has gone, you can still charge the phone but you may get no communications.

Sorry, not sure how that is supposed help. I mean, it doesn't give out much information.
Still, I know you tried everything, but either you keep doing something wrong or the phone has an HW problem. Did you try to see if Flashtool recognizes the phone while connecting it in flash mode (hold volume down with the phone off while you connect it to the PC via USB)? Maybe you could copy&paste its log after doing it.

device cant on in flash mode

I think it restarted on me as well a couple of times holding Volume down, once. That was because I took too long I believe. Try this:
1. Start Flashtool
2 Switch off the phone. Better if pushing the little bottom in the hole near the SIM card (it's faster and it resets it anyway)
3. Have your USB cable ready
4. Hold Volume Down and immediately plug the USB cable keeping holding Volume Down until the small led color changes
5. See what Flashtool is logging

i have allready do this bro just flashes on time green led thats all .... i dont know mayde have hardware problem ---->usb connector

It should flash led green just once and then turn it off, the point is to see what flashtool reports, it should say 'Device connected in flashmode' and that's it.

Hi,
I have a sony xpera L. It is stuck in a bootloop and i dont have CWM or TWRP. My device doesn't have a recovery mode. I already tried to fix this with Odin or flashtool but my PC doesn't recognize my device. When i try to connect my device to my PC i still hear the sound that it connects. My device isrooted
any solutions?

Are you able to enter the Bootloader/Fastboot?

I am able to start my phone in fastboot, my phone will show a blue light

PC doesn't recognise - Clearly means you don't have driverw for your phone installed.. A simple google search will lead u to them..

I cant install a new driver, my pc is pretty useless now since my phone cant conect to my pc.
thanks for your quick replies sir

Maybe install Ubuntu or another Linux and try again. Had the same Problem with Win8 and HTC of a friend.

Thanks for helping, i fixed my phone by flashing the stock rom. I used Wmshua for flashing. Its easy to use.

Nice to hear that

Is There any way to root and install TWRP without using pc ??

hello my firend, i want to ask you Is There any way to root and install TWRP without using pc ?? because my phone cant connect to pc and i have try everything and everyway from previous thread the result still same, the only thing i never try is flashing another rom. if i can install twrp so i can flash the rom without connect my phone to pc. i dont know what happen, i think maybe my usb connector is broken, but its brand new phone, so i think its imposible if the usb connector broke because i can still charge my phone. the only problem is it cant charge and connect to mtp mode when pluggen in to pc
