First off, I apologize if i epicly fail at this post since I am a n00b and it's my first time here, and I'm hoping you guys at XDA could help me with this, but My Tracfone ZTE Z667G (Zinger?) has many issues. It won't boot up past the ZTE logo, my computer doesn't recognize it, and I can't seem to boot into recovery. I am confused because I have not done any modifications to it whatsoever. I also cannot seem to find any stock roms for it or any tools to restore it. I've tried various ADB & Fastboot commands and it just says "waiting for device..." since my computer wont recognize it.
The battery is new and I need my data off of the phone and I have no idea what to do. Any suggestions? Thank you all in advance.

I am trying to use 'adb' from the android dev kit but I cannot see the devices, i.e. 'adb devices' doesn't report any devices. It appeared to be working earlier this evening but not any more. I was going to push a rom file to my rooted phone but obviously since I no longer see the device I am stuck. I rooted yesterday and installed the maximus rom but my phone went into a loop of restarting. Unfortunately I didn't backup before I rooted and installed Maximus rom.
Can anybody offer any help? I am using Mac OSX.
Desperate since phone is now effectively redundant

if it didnt help u just reply and we´re gonna look whats next to unbrick ur phone
Hi
Thanks for your reply, I have hit the 'Thanks' button
I read the posting you referenced but it doesn't really offer a solution to my problem.
As described earlier I rooted my phone and flashed a Rom (Maximus) succesfully but on turning the phone on after installing the new Rom I got into a cycle of the phone rebooting without actually getting past the lock screen. My thoughts at that stage were to re flash using stock rom but on running fastboot and plugging into my Mac OSX machine via USB, the phone doesn't show up in 'devices' on the Mac. I have also tried 'adb devices' form within Android Dev Tools and although 'adb' runs fine no device is reported. Of course without devices being avaialble to 'adb' then I cannot reflash!
I have also tried from within a bootcamp installation of 'Windows XP' installed on the mac with the same results, this with 'HTC Sync' installed and therefore providing the USB Drivers required within Windows.
I have tried logging into fastboot using 'power' and 'Down Volume' at various stages of the boot process on the phone but have never seen the phone within devices.
Clearly prior to installation of the Rom (Maximus) I could see devices at both the Finder window on the Mac and from adb devices.
Any help or insight you could provide would be very gratefully received
Ok ok ok dont worry
I had to read a bit and found quit much german threads where they flash back the stock rom
as is suggested u cant flash it with odin...
the only solution i woul suggest is that u have to find a computer running windows
there its very easy to restore the stock with the methods u described earlier in the thread...
hope u get done let me know what happend
=)
The question remains; how can I flash anything be it a hacked rom or an official rom when I cant see the 'device' in both windows and mac osx?
I think what I am looking for is a reason why the phone isn't seen when plugging in via USB. Once it is seen as a 'device' I will be able to flash anything via 'adb'.
Thank you for your continued interest and assistance
ok so u know how the get it back but ur phone is not really recognized by ur computer
but i found a method using the bootloader
the problem is that the instructions are in german
but i think if u google a bit u may find it
Don't know if I misunderstood what you said..but to get into recovery, you hold volume down and the power button when the phone is turned off. Not during the boot process.
Yes you can do it with bootloader (power+volume down)

Yes, I know that. He said he attempted to do that DURING the boot process. I was stating that he had to do it while the phone was powered down.
Guys, I can get into recovery no problem. The issue is that my phone doesn't show up in devices on the mac finder window and hence when I run 'ADB Devices' from the mac when the phone is plugged into the mac with USB no device is found and so no serial number is reported in my terminal window on the mac. If I can get to see the device with 'ADB' I can push the rom and recover the phone. At the moment the phone is bricked.
Thanks guys for your continued assistance.

But if this doenst work why dont u try the method with the recovery mode or the bootloader i suggested
Hi guys,
Wondering if anyone here has the know how to help.
Im fiddling with some new Kobo arcs, the 7HD and the 10HD and im having some bother with installing a custom recovery img.
For simplicity sake im going to refer to them as the same device as they are both behaving the same way
The device is rooted, and I am able to flash a custom recovery made by Jenkins builder but its not functional, when you boot to the recovery OS it just goes black and the back light flashes on an off (screen remains black it just lightens up)
At this point I can reboot as normal and adb to it and flash the original recovery img and all is well.
As far as I can tell its bootloader is unlocked but there might be a second bootloader im not able to interact with yet, possible called uboot?
From adb I am able to reboot the device in to bootloader and fastboot and both function as id expect, but the problem im having is booting directly to fastboot in case I bugger something up which would allow me to fix it.
I can boot the device in to a "mode" that tries to install an APX device, ive tried using various adb, fastboot, and composite drivers and nothing seems to work, ive downloaded some old NVidia APX tegra 2 drivers ive found but these fail to work with the NVFlash utility that comes with it, it says unknown device found, which would make sense given the utility is at least 3 years old
So firstly,
Does anyone know what might course the customer recovery rom to fail and yet flash like it is doing, if so any suggestions where to start to look for a solution?
Secondly,
Does anyone know much about this APX mode and how to actually put it to good use the driver appears to work and communicate but im needing something desktop wise to talk to it...?
hope you guys can help
edit
ive answered some of question 2 myself, it appears its a pain in the arse by all accounts and not as user friendly as I was hoping, I can send commands to it but it appears that commands may need to be "signed" of sorts as I don't get any response other than acknowledgment of the command sent, ill monitor the USB traffic and see if that sheds some light, it also appears that NVflash (not to be confused with its cousin in the GPU arena) is also hopelessly out of date and once again Linux is needed to get something more updated, if there is ANY help at all id appreciate some input

I know this is old, but how did you flash the original recovery? I think I need to do this so that I can install the update ZIP for the Kobo 10. CWM is failing to install the file.
Hey all,
So I successfully rooted my phone, and then I was going to go into recovery reboot mode to install a downloaded rom. I'm not sure what did it, but on that restart I got LG Security error. I first attempted on three different computers to do LG Mobile Support Tool. It stopped everytime when it was going to begin downloading the files. I'm pretty sure if I still had the Security Error image, I would be fine, because I now know of ways to bypass the LG Support Tool, and edit the host file, and then get it downloading.
Either way, in my research after no success with LG Mobile Support Tool, I came across Fastboot. So I got fastboot, I got the drivers installed, but I'm pretty sure my problem was, on the command prompt screen when Fastboot asks' you questions I said yes on them. I believe this is what caused my phone to have the black screen. It will not go into S/W upgrade mode now. It will not do anything, just black screen. I found a tutorial over on Android Forums, and with using Fastboot, I was able to sucessfully flash "p4_769.img" According to that tutorial, after doing that I should have a dead android guy logo, and then just be able to hard reset... but that didn't change anything. Still have the black screen. Still won't go into S/W Upgrade mode.
Now according to what I've read, the next step would be to flash KDZ Afresh...I've looked for this, whatever it is, specific to my model phone, but I can't find anything. If anyone else has any ideas, I would love to hear. I'm so frustrated at this point. Very much appreciate any help. Thank you.
It sounds like now what I have to do is, using how I flashed that recovery img, I first should flash the x and uboot.bin files to my phone. Then I will be able to get into S/W mode, and then restore from there. I just have to find these bin files. I don't have a friend or anyone nearby with the same phone as mine that can:
adb shell su -c busybox dd if=/dev/block/mmcblk0p2 of=/sdcard/external_sd/p2.bin
with theres.

Hello,
First off, I've gone through the forums and I have looked up other posts and despite everything I cannot figure out how to get my nexus 7 tablet to be recognized by the computer (I tried and after two days of searching for answers I decided to make a post). I like to include this information so people don't assume that I post without browsing or haven't tried anything yet.
The thing that I am having troubles with is that I have a nexus 7 tablet that is softbricked, I have already gone through a lot of ways to fix that problem (I found the best solution is this:http://forum.xda-developers.com/showthread.php?t=1809195). However, the issue is is that I cannot get my computer to recognize the nexus tablet to flash it and restore it back to factory settings.
I have installed and updated the device drivers on my computer, but still I have had no such luck. I found that ADB doesn't recognize the device whilst in the Bootloader, but still will not recognize the device in recovery mode. If anyone has any tips, or suggestions that might work PLEASE let me know, at this point I'm getting desperate and any/all help would be greatly appreciated!
Thank you!

adb is not designed to be usable in bootloader mode. You need fastboot for that. If you have the fastboot.exe program in the same folder as your adb stuff, try this:
fastboot devices
If it reads, then all you need to do is fastboot flash the various .img files back to the tablet. There are tool kits that do this for you, but I prefer doing it manually as there are less chances of things messing up and if they do, you're more likely to know at what step which could be useful for further troubleshooting if need be. It is important to download the correct img files due to differences between the generations and wifi / data enabled ones. There is a flash-all script that you can find in the download of the factory images, which might make it easier, but you can just manually flash the separate files as sometimes you don't need to bother with them all (like the bootloader) though if the script works, then it'll be fine and might make it easier if you are not familiar with the commands.
If you don't have fastboot at all, just grab it from here: http://forum.xda-developers.com/showthread.php?t=2317790

You won't get adb in bootloader mode.
You have to use the fastboot command.
Please tell the OS on your computer.
Use the tool in my signature as an environment.
Download 7zip, and install that.
Then go here and download the proper image for your device.
It would either be "Factory Images "nakasi" for Nexus 7 (Wi-Fi)" or "Factory Images "nakasig" for Nexus 7 (Mobile)".
Grab the 4.4.2 version.
Extract the downloaded file with 7zip into the "Work" folder in the tool form my signature.
Then extract that "nakasig-kot49h-factory-83d93b5f.tar" file with 7zip.
Then go into the folder that came out of that, and extract the "image-nakasig-kot49h.zip" into the Work folder.
And enter the following commands while in bootloader.
Code:
fastboot oem unlock
fastboot erase userdata
fastboot erase system
fastboot erase recovery
fastboot erase cache
cd nakasig-kot49h
fastboot flash boot boot.img
fastboot flash recovery recovery.img
fastboot flash system system.img
fastboot reboot
Make SURE you grab the correct image for your device. Wifi or Mobile.
I also assume that you know the .img files should be in the Work folder before you type thse commands into my tool.
Hey guys, first of all thank you for the speedy replies and steps I should follow.
Right now I'm using OSX but for the tablet I'm using a virtual Win7 machine to try and get this damn tablet to be recognized by the computer. The process is being delayed a little bit because my micro USB cords are being temperamental, meaning that the tablet has no juice, and when I mess with it (using the power + volume buttons to boot to bootloader/recover) the cord comes unplugged. I know automatically you guys are going to pinpoint this as the source of the issue (mainly because I would too), but it works fine if just laid flat and stays connected. It just has zero charge so when it disconnects/reconnects I literally have to power it back up, just need to wait for it to have some charge before I tinker with it more.
I will post updates after it charges.
Although I already thanked you guys, thanks again for speedy reply. It's much appreciated.

I suggest to STOP!!!
If you are trying to restore the device and the cable disconnects in the middle of it, it might not be recoverable. That would be one of the few ways to really damage the tablet as they are pretty difficult to hard brick. Don't half ass it with stuff like this. A good cable is not THAT much and will certainly be cheaper than a new tablet or getting it to a point where you might have to send it somewhere for service.
I'm not familiar with Macs, but if you are more so, then this might be better than using a Virtual set up:

It's actually working fine now (in the sense that the computer can now read it). The Virtual Machine also works just as good, but for some reason the toolkit I'm using won't properly return the tablet to the stock image using the SkipSoft Android ToolKit, so I'm going to have to try and find another way.
Thanks for your guys' help.
Hi there I think I have softbricked my Nabi 2. I tried to update the software from ICS to JB using files from the XDA Nabi 2 Wiki but have come to a massive problem. I can't boot back into TWRP because all I get is an Android laying down with an ! on his chest. I can't re-install TWRP because my Windows 8 PC can no longer see the device!! I can get into the tablet options menu with fastboot, forced recover etc. I think the biggest problem is getting the PC to see the device.
If I try selecting different options in the tablet boot menu then Windows will see the device as Android ADB Device or MTP USB Device.
Can anyone help me get over this problem? I'm not used to using shell commands but fear I will have to install the Android environment to use ADB to get things working.
Please help if you can as this tablet belongs to a nephew of mine and he is missing his YouTube. I am close to tears trying to find the solution. I have read and re-read XDA posts in case I missed something.
Many Thanks In Advance.
