not even via adb?
Hard luck.
Hope you didn't pay for it.

Yes. But adb sideload is working. But it saya can not read install.zip or bla bla. I checked the screen i saw footer is wrong. What do you think? I guess if adb sideload does work i can change the firmware but how?

Afaik you can't change/flash system via sideload.
As long as you can't get it into download mode I don't see a chance.
To be precisely: "adb reboot bootloader" isn't working?

Bootloader unlocked, now...confusion.

I'm having trouble getting this POS rooted. Got it unlocked with little problem, but now that it comes to rooting, it's extremely confusing to follow the tutorials. Is there any working one-click methods? I'm no stranger to Android OS, I had my Dinc2 rooted in about 5 minutes after unboxing. But this abomination is really working my nerves. Help please?
There is no "One-Click Root"
But rooting using the given instructions is not difficult at all.
Its as simple as downloading a few files, and typing a few codes.
what have you tried so far? and what firmware are you running?
Since you unlocked your bootloader,here is how you get Root
http://forum.xda-developers.com/sho...m.xda-developers.com/showthread.php?t=1130639
download the .img ,put it in your fastboot folder
download the rootxperia.zip to your SD card
Turn phone off,plug into your PC/Laptop and hold search button ( might take some tries) ,you should get BLUE LED
SHIFT+RIGHTCLICK on fastboot folder and open in command window (assuming your usiing vista/win7) and type
fastboot boot recoveryPLAY.img
wait 2 minutes,it takes time.
Apply zip from SDcard and you are rooted

the wait for recovery to load is HORRIBLE!! lol. push the menu button once in a while if you are unsure. i did. it makes the wait (for me) less painful but installing the .zip and rebooting successfully with a rooted phone is AWESOME!!
Thanks for simplifying it for me Cat. I'm sitting here with my blue LED, my blank screen and my command window that now says "waiting for device" so that's what I'm doing. Waiting. Smoke break time.

are you sure that you installed the "S1Boot Fastboot" driver completely ?
cause i had some problem like yours ... just go to my computer=> right clik => manage=> devicce manager
and check if it's already install or not (( other devices ))

Sony Ericsson sa0102 is installed, but I'm not seeing anything in my device manager about S1 Fastboot. Hmm...how would one go about installing it? I have the fastboot folder on my desktop. It has two subfolders, Fastboot and USB_drivers .

In this case if it's either still 'waiting for device' or trying to boot recoveryPLAY.img, then you're safe to try again since nothing is being flashed
When connected next time, in fastboot mode, before booting the .img, type this:
fastboot devices 'enter'
It will show a list of devices attached.
It might be that your missing some drivers so fastboot is not working correctly and won't detect your device. Have you pc companion installed? I don't remember if there came any drivers with the fastboot download but check that, there might be some drivers you didn't install.
Regards Dousan...
This is what happens. I just get another prompt. Here's a screenshot of that, along with the drivers folder.

That means no device is connected. Unlike ADB, fastboot does not return the usuall "list of attached devices" line. Have you installed fastboot drivers?

I don't know, I just installed what the guy told me to when he did the remote bootloader unlock. Fastboot IS in my device manager, however, it says there are no drivers installed. I've got the blasted things on my desktop with some DPInst.exe installer, but it says I need the 64-bit version, which I can't find. Microsoft tried to have me download some silly .ISO file but I really think there must be an easier way than to burn some DVD installation disk.

Ok these are the x32/x64 fastboot drivers.
http://www.multiupload.com/0XZV1LXRVA
Download them and unpack them. Connect your device in fastboot mode. Then navigate to device manager on windows, Find the S1 Fastboot thats not installed correctly. go to update driver and navigate to the driver package you just unpacked. Done

I did it. No, f**k that, you did it. All of you, thank you so much. You guys really helped me out bigtime, without berating me and calling me a noob lol. I sincerely appreciate it.
Also a special thanks to Alejandrissimo for unlocking the bootloader. Without you, this wouldn't have even been possible. Yay this blasted phone is finally rooted...
...and nobody had to die in the process.
That's what we are all here for. Learning about things through each other. We were all without knowledge at one point

[Q] Device not detected only on recovery mode

I'm trying to update my G Watch by sideloading a zip file.
I installed the sdk tools and usb driver as usual.
On debugging mode and bootloader, the watch is detected as an ADB device normally. 'adb devices' command works.
But when I reboot and get on recovery mode, the watch disappears on the device manager and never get detected again. So I cannot use 'adb sideload' command.
I've never experienced this kind of issue with smartphones.
Do you have any solutions?

Ok, does anyone know how to get my computer to recognise my watch in recovery mode? It's not about 'driver' the computer plain doesn't recognise that anything is plugged in at all.
I know the post is quite old already, but I experience exactly the same phenomenon...
I tried multiple PCs Linux and Windows,but non of them recognized the watch (neither on 4.4W1 nor on 4.2W2).
Anyone any idea?

The problem, as @osikiri stated, is that the device does not get recognized at all (no unknown devices in devicemanager and the sound that comes on plugging in a device does not come as well). Furthermore, afaik Linux does not even need any drivers

If this really helps (seems weird): I guess the exact setting could be necassary:
You simply ran out of battery while the watch was running(not recovery or fastboot) and then plugged it in and went directly (or not?) to the recovery?
Thanks in advance, would be really great to fix this!
Anyone ever find a fix to this? I'm trying to manually install the 5.0 update and I'm having the same issue. Every post I find with search tells me to update drivers but I'm on a Mac that doesn't even use ADB drivers. I've updated the SDK.

I'm doing the same thing and having the same issues!
Yeah, same issue for me as described.
Windows (Win7 x64 for me) doesn't even realise that the device is connected when it is in recovery mode. Although it will connected properly when booted normally.
+1 Any ideas?
Same issue for me. I've tried removing and replacing it on the cradle, killing and restarting the adb server, entering recovery by the touchscreen or by the adb/fastboot commands, clearing debugging keys, etc... Anybody have any other ideas?

Ok, so it appears that the recovery img on 4.4w2 broke adb support or something. There are a few threads that suggest you can root and flash it or just wait for the OTA. We'll see whether I get the OTA before I have time to try this out.

I've similar problem, and I've spent almost 3 hours to find the solution. I found that following solution work for me:
http://forum.xda-developers.com/g-watch-r/development/manual-ota-update-root-t2969845
I've changed the step slightly according to the comments inside the thread:
- Enter Bootloader (swipe top left-bottom right as soon as the LG logo pops up on boot)
- Unlock bootloader (fastboot oem unlock) and boot the watch normally once
- Turn off and re-enter bootloader
- Flash 5.0.1 Stock Recovery (fastboot boot recovery.img)
// Do Not Flash 5.0.2 stock recovery
- Enter recovery and ADB sideload the update (tap the android, select install update from ADB and enter adb sideload filename.zip)
//you might have to reinstall the ADB drivers, just follow the simple step to install ADB driver
Done.
fi thought it was finally the solution, but fastboot oem unlock bricked my sony smartwatch3. I see tomorrow if with my windows pc i can fix with sony companion, otherwise i'll have to use the warranty

I didn't need to enable unknown sources or usb debug because there was no system to begin with. I hope it helps you.

[ROOT] How to root the new Wiko View

Hey, I'm french so if I do mistake, it's normal, sorry
Here is a way to root this Wiko, finally!
Before doing this, i want to say that me, XDA or nobody exept you is responsible of what you can do on your phone, this method work for me, surely for you, but this operation will delete all your data, so remember to backup your data.
Now, you Have to go to Developper options, enable "OEM Unlocking", "USB Debugging" and disable "Verify apps over USB"
After, set "Select USB Configuration" to MTP. After That, download file (https://mega.nz/#!ioBQDZra!z6ntj85aM-mjg4dnscPaPBjvd-qpSY9HQiDkKuYbxcU) and extract it
Connect your phone to your Computer, Copy and Paste the SuperSU zip file in your SD card, and reboot your phone in fastboot mode (shutdown, and boot it by pressing Power and Vol+, then, when you have a choice between recovery and fastboot, select fastboot by clicking Vol-)
Open a command prompt in the extracted file, and type: fastboot oem unlock
Here, all your data will be lost by a factory reset.
When the phone restart, in the command prompt, type:
adb root
adb shell
cat /proc/partitions
ls -l /dev/block/platform/soc/7825900.sdhci/by-name/ (7825900.sdhci may be different, so use tab to find the correct file)
in the list, you will have a file with "recovery -> /dev/block/XXX" (XXX may be like mmcblk0p22)
cat /dev/block/XXX > /data/local/tmp/recovery.img
exit
adb pull /data/local/tmp/recovery.img
adb reboot-bootloader
fastboot flash recovery "CUSTOM recovery.img"
fastboot reboot
if there is no problems, you phone restart normally, so stop it, and boot to the recovery (Power and Vol+ and whene the choice appear, Select recovery with Vol+)
if your phone don't want to boot to the TWRP recovery, try to flash the stock recovery, reboot and flash again the custom one. if the problem persist, leave a comment.
In TWRP, swipe the button, and go to Install, Up a level, select external_sd and then, select the SuperSU file, select "Reboot after installation is complete, and swipe to flash.
When it's done, install or not the TWRP app, and reboot. The device can start twice before finally boot, and can be longer than usual, but don't do anything, it's normal.
When the phone finally boot, SuperSU may be installed, so go check if it's true, and if it is, go to the play store and install BusyBox (by Stephen (Stericson))
After the installation is complete, open it, and click install.
If there is no problem, the root acces will be request, so accept it and all is done.
If you have a problem, or any question, ask me.

Oh, well, it figured my way out! First SU installation, the phone isn't rooted (I don't know why, either). But I factory reset the phone, set the phone up, then go to TWRP and re-install SU and it worked. Now the phone is rooted!
Thank you very much for your guide and files.
By the way, I guess most people will get stuck at "adb root" command.
Simply dial *#*#84666364#*#* (this launches TinnoEngineerMode)
- go to "Tinno Debug Feature"
- tap on "persist.tinno.debug" and choose 1
Then you can go on with "adb root" command
Hope this helps!

please help me to root my wiko view 32gb+3gb. i place fastboot oem unlock in pront comand i see waiting for device, and nothing. please creat a apk our anything for root
Would it work on k-Kool ?
We'll this sounds horrifying, just to get root permission, you have to accept to get rid of all your data and parms ? It must be another way.
I'll explain my real need for rooting my Wiko k-Kool. I bought a 64GB SD card, to be used normally as external storage, not for apps install. However I want to be able to backup my phone onto that card, just in case. I use Helium to backup my data without needing root (uses internally adb) ! However non-rooted Helium as a 3d party application has no permission to write to the SD card ! The reason I want to root is just to give Helium the permission to wirte into a backup directory.
Therefore I dont want to put my data at risk just to get root permission, but found no other way to change heliums permissions.
Thanks for any help.
