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

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
Hello All,
I've been rooting etc for a few years now, but last night I ran into my first snag I can't seem to get out of. I was attempting to install Viper 3.0, I had flashed in twrp2.6.3.0 beta like they said to do. Went through the wipe, etc installed and it failed. Message was along the lines of "Failed: Installer status 7." So i went through the process of trying to again, but now I'm stuck in Recovery or hboot/fastboot. I had to reinstall Windows 7 on a old hard drive because the whole Windows 8.1 thing doesn't work right. So I can see my phone in adb in WIndows 7. I've successfully pushed twrp2.5 to my phone, but I can do nothing else. I've tried sideload, but that won't work. At this point the main thing I'm trying to do is push an older ROM over to my phone to see if it installs correctly, but I can't seem to even push files in adb. Any help would be greatly appreciated on the matter, as I'm sure I'm overlooking something.

Put the phone in recovery mode and plug it into your PC, and make sure adb devices shows your serial number. Then you should be able to just run
adb push C:\path\to\your\rom.zip /sdcard/rom.zip
Then just find it in recovery and flash it

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.
Hello XDA community, this is my first thread, i had never needed to post anything cause i always find everything im searching for in this awesome community... until now :crying:
Last week I got a new android device which is made by Polaroid, model: PSPR355, its a pretty low class device but I thought it would be enough for me.... then i realize I needed root permissions, for obvious reasons... easy I thought... i had rooted many devices...how hard can it be...right?... WRONG! :crying: . The first problem I encountered were the drivers..couldnt find em anywhere... fortunatelly i found a tutorial were i could install the drivers in a different way...although I took 2 days to do this...Ive been about 5 days trying to root my phone.... Ive tryied about 10 different programs with their different versions... and any of those rooted my phone, nor Oneclikroot, nor Unlockroot, etc, etc..... I really gave up trying to find something on the web cause i didnt even find the phone on its official site, so I came her defeated asking for any solution, idea, or if you want to help me with commands, a programm or anything else to root my phone, Im not even afraid of trying programming (Im trying to learn how to make roms, kernels, etc for this phone cause theres nothing on the web abou it but this is a theme for another time) if you wanted to help me i would really appreciate it, im a little desperate so anything would come useful thanks everyone and I hoppe you can help me!!! :fingers-crossed:

I would recommend trying the towelroot application. It can be downloaded from here, just click on the orange lambda to download the tr.apk file. Then open towelroot follow the instructions in the application. After the device reboots I would recommend downloading, Root Checker Basic form the Play Store and running that to make sure your device is rooted. Finally install SuperSU, and you should be good to go.
First thanks for answering so fast shimp208! And I guess I forgot to tell that I was in Mexico and Im using Telcel's network, I downloaded and installed the apk file but it doesnt starts I click the button pops up a black screen and then closes to the last app I used...any idea about this error...or if its beacuse of the carrier, by the way the device has Android 2.3.7 I dont know if it has something to do with this error

Does it present an error message of any kind before it force closes? Try uninstalling and then re-installing the application, and if that doesn't work go to application manger under settings, find the towelroot application and select the options to clear it's cache and data. The carrier won't have any effect in this case, and with it being Android 2.3.7 your device most definitely has a kernel build date before June 3rd, 2014.

No it simply closes without showing anything, and without even giving the "Force Close" message, i thought it was because i first installed it on the sd card, or because of not enough space but no, I moved it to the phone and uninstalled some apps I had, I uninstalled and installed towelroot twice and it didnt work, I installed the v1 of it and i got to the [make it ra1n] screen but when I click the button it closes immediately again without any error message

Very interesting, while in theory the app should work for any kernel build date earlier then June 3rd, 2014 the app many not be compatible with devices running an Android version less then 4.x.

Since you have the usb drivers working on your computer, try booting into the bootloader and using fastboot to see if the command fastboot devices returns anything. If the computer see's the device in fastboot that's a good sign. If your device doesn't have a locked bootloader which it likely doesn't, then I can try and create a rooted system image for you to flash in fastboot. Provided fastboot see's your device if it does, if you can provide me an adb dump of your /system folder then I will see what can be done.

Unfortunately if fastboot doesn't show your device without any other flashing utility, even with the system dump there is no way to flash a rooted system image if it was created.

Hello shimp well I connected my device on FastBoot Mode and my computer recognized it and it installed a driver named: ADB Testing Interface I dont know if thats a good sign or what should I do, I tried entering into recovery mode but it shows only an android little guy and exclamation quote... so I think it doesnt have a recovery boot I dont know if thats relevant, Could you help with the adb dump i dont know how to get it. And.... I dont know if besides you help me with the rooted system image you could teach me how I do this.... anyways thanks a lot for helping me! I'll keep doing everything you need so we can root this device!

Since your computer recognizes the device and installed the driver and shows the device when in fastboot mode that's a good sign. The Android with the exclamation point is part of normal stock Android system recovery, it just means that the recovery menu has been hidden (You should be able to get the menu to appear by pressing the power and both the volume buttons in recovery mode). To dump /system run the following command:
Code:
adb pull /system
Then please send me a link to the /system dump, from there I will make a rooted system image.
Factory Rooted??
Hey guys I'm new to this so I may be wrong but has anybody thought to check if the Polaroid PSPR355 comes Factory Rooted??? I had a Polaroid Tablet, PID something(I forget the name), which I tried for hours to root resulting in: bootloop, hard reset, root, bootloop, hard reset, root, bootloop, hard reset, about to give up. So I Googled how to root Polaroid PID something (again, I forget the name), and I come to a post somewhere(forgot that too) that tells me my Tablet and similar Polaroid electronic devices(as well as most electronic devices coming from China) are factory rooted due to some Chinese law. So after the last hard reset, I downloaded HowToRoot App to check if my Polaroid Tablet is, in fact, rooted. I press the little lock button(root checker) and I find that, to my surprise, my Polaroid Table is in fact rooted. So all I had to do was download SuperSU from Google Play Store and Update Binary when prompted and I was Super User. Don't know if this helps but it worked for me.
I'd like to start off by apologizing for having to waste somebody's time for something I can't find the answer to. I should preface this post by saying that I know nothing about ADB, but in the last couple of days I've done plenty of reading and to be quite honest the more research sometimes adds to the confusion with contrary and outdated information.
I'm basically trying to get TWRP onto my Mi Pad 4 LTE using ADB on my Windows 10 PC coming from the MIUI EU ROM Bootloader unlocked from the supplier. USB debugging enabled drivers installed etc
I had a lot of trouble until I came across this thread http://www.testedtechnology.co.uk/debloating-the-huawei-p30-pro/ because of an error I was getting in the Powershell window.
https://forum.xda-developers.com/attachment.php?attachmentid=4781060&stc=1&d=1561218064
So basically in short, thanks to the above thread I was able to get into fastboot mode having recognized the device using the precursor .\ as shown above, but one of my problems is I'm not sure if I should be use the .\ with all commands? My problem from here now that my device was in fastboot mode I didn't know how to direct it to the file. I just have no idea what commands to you use to find a particular directory to get to recovery-TWRP-3.3.0-0429-XIAOMI_PAD4(PLUS)-CN-wzsx150.
I'm really concerned about putting the device into bootloop as some of the problems I've seen seem almost insurmountable!
Anyway sorry again and TIA for anybody taking the time to help.
All sorted now thanks for all the help.
