fastboot doesn't see my phone - Nexus One General

Hey guys,
Yesterday I unlocked my bootloader, and rooted my phone for further flashing of the latest CM rom.
Today I wanted to finish what I'd started by flashing the radio img into it, which i've read there's no problem doing so after completing the rest of the process. However, fastboot devices won't see my phone and adb devices (with phone on) says the following:
Code:
List of devices attached
???????????? no permissions
I had seen this before and yet I could access it with fastboot, but not anymore.
I haven't found any thread on this so if someone has an idea regarding what might have happend I'd greatly appreciate it.
Thanks!

Make sure you have the correct drivers and usb debugging on

Sorry I forgot to say I'm on Ubuntu 9.10, so there is no need for any drivers as far as I'm concerned (I didn't need them the first time).
USB Debugging mode is ON.

Yeah, I had the same problem. It's already been discussed in the forums (search!).
This is the thread that fixed it for me:

how to unlock bootloader 4.2.2?
yes usb debugging is enabled
I assume you are using Google Nexus 7 Toolkit?
If so there should be an option which says unlock bootloader.

I feel your pain as I too am having the same problem. I am posting on here so I can easily follow your post. I will tell you also that I think it has something to do with 4.2.2 but not positive at this point. I have rooted a Nexus One, HTC Dream, SGH679, so I do have some experience with this. I have changed ports, cables, started and stopped the service, rebooted the tablet, toggled the debugging just keep getting the offline. When I plug my phone in and use it, it sees it and it works fine, then when I plug the tablet back in it go back to offline. I even removed all the drivers on the computer just so it would get confused with the phone driver and still no luck. I think the driver is fine tho because it says it is in device manager, and I can transfer files back and forth from my tablet to my computer. Don't loose heart tho I think the answer is out there and I will keep working on it, and checking back to see if anyone else has had success.
Have you tried updating the data files in NexusRootToolkit?

So I was going to do it the old fasion way by following this guide
http://forum.xda-developers.com/showthread.php?t=2150661
I didn't quite get step four because the nexus 7 doesn't have an SDcard, but I copied the zip to the root of the device.
When I did step 7 the device did not go to Fastboot, it didn't go anywhere other than a black screen. I think I have a faulty unit, or the holding of the volume buttons with the power is really not the way to get to fastboot, either way I am looking at a brick right now. Any thoughts will be welcome. I messed around with it for 10 min now and got the device to re-boot. Not sure if I should try the fast boot option again.
Are you on Windows 8 by any chance?
Because I couldn't get it to work on Windows 8 and had to use Windows 7.

everyone i got it working! adb offline fixed
It took me a while but I finally fixed it! Here's what I did I went crazy and searched all over the web with the keywords adb offline nexus 7 4.2.2 I then found a website that related to my issue it said to update SDK manager so I downloaded the manager then found android 4.2 next downloaded all that was under the 4.2 package and next downloaded the extra packages next thing I knew I plugged in my nexus and on it on the screen it told to choose yes or no on USB debugging and that's all you have to do to fix the problem of the adb offline bullstuff. I hope you guys will be able to understand what I'm writing to you. I also use windows 7 for this.

FWIW, here is my experience:
PC: Win7 Pro x64 SP1 - SDK platform-tools 16.0.1 - SDK Tools 21.1 - ADB v 1.0.31
N7: JDQ39 Stock *
( *OK, i diddled default.prop in my boot image to set "ro.secure =0". I don't know if that could make a difference or not )
The Nexus 7 asks for confirmation of inbound adb sessions for every new adb server invocation on the client PC.
When it does ask for credentials, you have to get to the on-screen display pretty quickly - a couple of seconds at most. If you don't the device will be reported as "offline" by the first invocation of
adb devices
If you accept the connection, the next time you run "adb devices", the status is back to normal (reports "device" instead of "offline").
You can test this out yourself - just iterate in a loop these three commands:
adb devices
adb devices
adb kill-server
Nothing that can't be understood by someone who knows what is going on; but I suppose that all the toolkits are running adb underneath the hood, so it is certainly possible to get tripped up when using a toolkit if you aren't Jhonny-on-the-Spot when that dialog pops up on the tablet.
Also, for the adventuresome:
I note that the new stock JDQ39 (4.2.2) ramdisk has a new line in the default.prop that was not in JOP40D (4.2.1) :
Code:
ro.adb.secure=1
I suppose that could be toggled off if you have a favorite kernel/ramdisk setup and you don't want to be bothered by this stuff. But it does mean unpacking/repacking your boot images.
cheers
I'm having the same problem. Never recognizes an ADB device. When it does it shows my serial number followed by "offline."
Any ideas? I'm ready to return this thing.

Out of curiousity what driver are you using and how are you installing it?
Also where is your device coming up in the device manager?
I've tried so many things that I think I'm getting off track. Sadly my motorola phones were much easier to root.
how come you cant?

The sad thing is I have no idea what finally got it to work. Maybe just an extra reboot I had forgotten at some point. I do know however that I had to add a few extra lines (hardware ID) to the .inf file in the usb driver. Not sure which did the trick. I also used a combo of the toolkit to unlock and the manual method to root. Also I am unable to boot my device into the bootloader/fastboot via windows and rather have to manually (physically) shut down the device and enter the bootloader via the physical buttons. Probably an issue with the windows drivers again, but at least I have full functionality once in fastboot.
Only thing is now I can't get access to the storage via windows. And there's no way in hell I want to change the ADB drivers without knowing which finally worked for me. I'm thinking though that this is an entirely different device in device manager (I'm obviously not that knowledgeable).
Also I'm kinda annoyed by the unlocked padlock symbol on startup. I suppose that should be a welcome sign of achievement after spending all day trying to unlock/root, especially for such an unlearned person as myself.
did you clear this issue?

cause I'm a noob, I cannot use link here. :crying:
This issue is included in 4.2.2, and ADB is disabled by default for security.
I tested on my Nexus 4, 4.2.2 running. :fingers-crossed:
Okey. So to summarise: there is this new security feature in android 4.2. that makes the device show a popup if you want to allow the connected computer to use the adb = debugging bridge. But for this to work, you need to have the newest adb binary, which needs to print 1.0.31 when you run "adb version"
(found that info here --> http://www.androidpolice.com/2013/0...s-from-stealing-your-data-in-some-situations/ )
Under linux when you try to do it the old-school google-recommended way and download the huge "adt-bundle-linux-x86_64-20130219" and use the "android" tool to find new updates to the platform tools, it will tell you you already got the latest version which is rev 16.0.2 which contains an adb binary which will print version 1.0.26 which will not work with this new android 4.2.2 security feature.
So after searching for a linux adb 1.0.31 binary, I found it here:
https://github.com/mozilla/r2d2b2g/commit/2eefcc05366173ca51635da8f542fd8473ba0fea -->
https://ftp.mozilla.org/pub/mozilla.org/labs/r2d2b2g/adb-1.0.31-linux.zip
with that binary I finally can use adb on my nexus 7 again.

[Q] Droid Razr M not fully booting: Help Please

Hello,
Problem:
factory reset my Droid RAZR M with the hope to resolve in-call audio problems (very low ear piece volume at full). When I rebooted the phone the Welcome screen appeared asking for a language choice. Chose english US. The Message: "Please wait, This may take a few minutes" appeared with a spinning icon. But nothing else ever happens. The phone never moves beyond this selection.
I have android-sdk (Linux setup) installed on my computer in order to use the suite of tools like fastboot and adb. The tools work, in that I can see the phone, pull data, upload to the phone and even get a command shell on the phone. However in order for adb to recognize the phone I have to put the phone in "BT Tools" mode. In "AP fastboot" mode fastboot sees the phone. As far as I remember USB debugging was turned on.
I do not have a recovery image installed.
The phone has Kitkat 4.4.2 ver 183.46.10 and is rooted with TowelRoot. I just unlocked the bootloader today via motoapocalypse package. Status of the phone is unlocked Code 3
I also removed some unused apps - like NFL and a few other space and bandwidth consuming apps that I will never use.
I'd like to get this phone to work again. Is there any hope?
Please advise and thanks for reading.

[GUIDE][FAQ][DIY][KK] How to Root, Boot Unlock & More
Thanks for the pointer. I gather that RSD is a Windows based app. At the present time I do not have a Windows computer. So I took a shot at the job using fastboot, adb and all as found in the android-sdk. Did the steps as described in the flashing post. Now all I ever see is the "Bootloader unlocked warning message" and the phone never progresses beyond the warning. I disassembled the phone, to disconnect the battery -- hoping for a reset miracle. No change after reassembly. Given the latest state of the phone as described above, is there any chance of reviving this phone now that it's stuck at the bootloader warning?
(I read a post about a Motorola Factory Cable -- and if I understand the factory cable puts the phone in a special mode for flashing looking into this option).
I am out to learn and am not afraid of poking around -- so at this point I have no more to lose.
Would the Windows computer make the difference? Using linux mint atm.

You can try using SBF_FLASH or mFastboot-v2 (which has a linux version) to flash the system.img .
SOLVED: [Q] Droid Razr M not fully booting: Help Please
That worked. Thanks! So the difference between the SDK fastboot and the one in the link provided (mfastboot-V2): the linux-fastboot seems to be smarter about uploading the larger image files to the flashable device (guessing). I am sure I did "flashboot flash system system.img" with the flashboot util from the SDK.
@ATTACK do you have the source for that version of fastboot or patches? Would like to have a look.
Thanks again! Got an unlocked rooted working Droid RAZR M!

Your guess is correct, mfastboot allows you to flash larger system.img's that wont otherwise flash in fastboot.
As for sources... I have no idea who created mfastboot or where it came from. It's just one of those things that get's passed around the internet.

Well I'm happy to have the utility that works. Can thank you enough -- or the creators. Found it also on goggle code after a properly crafted search string. All this for an in-call audio problem that only worsened after I took the phone apart. Still works on speaker mode though so that's good enough -- at low volume. And I learned a few things. One interesting thing: The shell prompt got rewritten to say ${USER}@scorpion_mini/ after flashing the system.img. Pretty sure it only said android prior to re-flashing . And the getprop helper app is a new thing for me.
Feel like a kid all over again exploring this little device.

I have been trying to get this room to work but failed everytime, because of the encryption.
Everytime I get decryption successful but something went wrong. As far as I understand the encryption should be disabled on this ROM completely, but I can't get it done. I tried reformatting data to ext4 but that didn't work.
Edit: The problem was that I was using Magisk as root solution. I tried with the provided SuperSU and it all worked.
My device runs well with rr. I only notice the performance issue on startup, right after but the phone is very slow.
I noticed that there is no swap memory use in this ROM, while in stock there was a deal memory partition.
I'll try to figure out if we can enable it in this ROM. That might improve performance.

I'm not sure which post you saw, but I think my post on there were with an other device and yes, I have never bricked a device unrecoverable (yet).
That said, you will always be taking a risk when rooting or trying custom ROMS.
Then again if you never take risks you won't get anywhere. The question is how much are you willing to risk. In this case are you willing to risk your phone for the extra possibilities you might get when rooting it
First think you need to do before modifying anything is learning how to backup and restore.

Thanks JudgeDread. Yes, I've rooted several phones in my life time. I understand the risk, but I tend to research about that particular rooting method with my phone before going ahead and doing it. I feel like the rooting method for my phone is particularly more risky, not because of what I read but rather from what info I am NOT able to find. Did you have a Huwaei Y5 2017 MYA l22 that you rooted successfully without issues? Can you point me to the instructions? That thread is a bit confusing.

Yes exact same model, rooted and after several tries custom ROM.
I unlocked using the official method and then flashed TWRP in the recovery partition.
The difficulty was to get back into TWRP after rebooting. So I would advice to immediately install a root solution. I used Magisk. While root works without problem Magisk modules will only work if you use the f2fs workaround.
I am now running Resurrection remix (Android 7.1.2) without many issues. Only every now and then a forced close of the system UI.
It took some time to get it running. Because I used a different root solution the provided on the same page as the ROM. So on install use the provided SuperSU. After install you can change of you want.
Also the patches are needed. I still have bad videos on YouTube but haven't looked into the issue much yet.

I am not an expert but I can follow instructions! Any step by step guide on how to root it? So far I've gotten the unlock code from Huawei.

For rooting you need unlocked bootloader ( if you don't do ir then below won't work).
1)download the 4pda app from google play store and register an account .
2) download the TWRP.img file from 4pda website here is the link
https://4pda.ru/forum/index.php?showtopic=823938&view=findpost&p=74424572
3) enable developer mode in your phone by going to setting about phone , tap 6 times on the build number.
4)go to developer mode and enable usb debugging and oem factory unlock .
5) go to your pc install adb here link https://forum.xda-developers.com/showthread.php?t=2588979
6) now conect the phone to the pc and run cmd , type adb reboot bootloader . (Your device ahould restart and enter bootloader mode (white screen)).
7) now take the TWRP.img (must be copyied to desktop ) and type in cmd cd desktop.
8) type fastboot flash recovery TWRP.img (change the file name to TWRP ).
9) type fastboot reboot.
Now you have successfully install TWRP on your device.

HELP: Rooting Essential PH-1 on android 9

Guys, I'm at my wits end here. I don't know what to do. And it's driving me crazy.
After saving for 3 months, I got a used Essential Ph-1 from craigslist (for sprint). It came with Android 9, and a February 5, 2019 security patch.
All I want to do is to root the phone. And I have tried everything in my power to get it to work. It just does not. I have unlocked the bootloader, I'm seeing the device in adb and fastboot, but unable to sideload, or flash anything. I've been following different threads on here and youtube looking for directions, but my phone will just not do it.
Can someone please help me? I will send my phone over to you and pay you to have it done. I've tried almost everything to do it, and nothing works. I've even tried to flash android 8 and 7, it still doesn't do it. Someone please help me. I don't know what more i can do. Any guidance is appreciated.
Can someone please help me? I don't know what more to do. Please.
Can you temporarily boot to twrp?
Are you using fastboot.exe from the essential ph1 driver folder?

No. I can't sideload or boot into anything other than the android 9
I also bought my PH-1 on CL, but it was an open market version. I can only outline what I found on this forum, and what worked successfully for me... I assume you are on Windows. First off, make sure you install the drivers provided by Essential, and use adb/fastboot that comes with it (it gets installed and put into the system path when you install the drivers).
I didn't care about TWRP, so the only thing I needed was root. So, after unlocking bootloader (and also unlocking critical, as recommended), I simply followed the steps to install Magisk, which are really straightforward:
https://topjohnwu.github.io/Magisk/install.html
Just use the "Boot Image Patching" section.
That's it. Works perfectly, and I just need to repeat the patching after OTA updates (there is a thread about this procedure specifically).
If fastboot flashing doesn't work for you for some weird reason, I don't have any good ideas about that, sorry! Sounds like you are able to get into the fastboot mode (since you are saying you can see your phone in the device list), so why it wouldn't let you flash is kinda baffling...

I tried that too. But it kept saying unable to unpack boot image | installation failed.
I tried it with the stock images from the Essential website, both the OTA and fastboot versions. I'm getting the error for both files.
I would suggest checking out the PH1 Dev telegram group https://t.me/EssentialPH1DEV . not only will you find pre rooted stock boot images along with ones with TWRP as well you will also find help flashing them if you need it. Hope this helps you out.
Thank you everyone for all your help. Special thanks to kt-Froggy. I got it to work. I had to change my usb port from 3 to 2 and i was able to get it to work!

Root Samsung Tab A SM-T510

Hi all,
I've been trying for hours to root my Samsung Galaxy Tab A (SM-T510) and am completely stuck...
I have managed to unlock the bootloader, enabled developer mode, that is fine but when moving to Odin I'm getting stuck, have read all kinds of guides and can't get past the next stage.
I'm actually unclear as the the correct steps, my only reason for rooting is because I need to issue this command so that I can have the device boot automatically when the charger is connected:
Code:
fastboot oem off-mode-charge 0
Do I first use Odin to load twrp and then I install the ROM? I'm not sure of that part.
One other thing I'm noticing is that when I try and and use Odin to flash twrg is that on the tablet in red it says 'Only official released binaries are allowed to be flashed', is this relevant and how to resolve?
One thing I have successfully done is to flash back the stock ROM from Sammobile (via Odin) and that worked fine.
Would really appreciate some help on this. I do not have a preference on which ROM to load, I just need to be able to run the above command.
Thanks in advance!
There are a lot of great video tutorials on YouTube. Just search for Odin flashing tutorials and watch a recent one.
Also these types of posts should go into the General forum and not the Development one.

Samsung devices do not support FASTBOOT nor do they have a FASTBOOT mode, So you will not be able to do this even if you root.

RTFM!!! There was a post just yesterday in the discussion forum on how to unlock the bootloader and that has to be done FIRST. Until recently, the only Samsung tablet with locked bootloaders were those tied to a "carrier". That is no longer true. In oder to flash ANYTHING other than a stock ROM, you must first UNLOCK THE BOOTLOADER!!!!!!! And you DON"t do it with ADB or fastboot.
