Cannot access adb or fastboot - General Questions and Answers

I have a nexus 5 and am using wugfresh root toolkit. My phone is unlocked, yet somehow i cannot relock it or install any roms because the toolkit does not read that i have adb drivers or fastboot. unfortunately. to install adb i need fastboot and to use fastboot i first need adb it doesnt make any sense. I cannot figure out how to get it to work properly at all. Please help.

All problems solved !!
Thanx guyz for this post...
Now my a7 is working fine and smooth with the ics refresh ver 2 rom

The above response appears out of place. In any case regarding the above, try going into stock recovery (android w/red triangle) then press power on button while pressing middle of volume. This should give you the ability to toggle to sideload option. If you choose this option while your phone is connected to a pc, you should have adb access.
Good luck.

Thank You both
Download supersu.zip onto phones internal storage.
Fastboot flash or boot custom recovery.
Flash supersu.zip from recovery
Stock rooted.
Easiest way. Best way. Never fails way. The same way the phone was rooted in the first place.....
can't get Shabby's way to work. just searches for devices & on my phone it stays at the bootloader screen. how can I flash something if i'm unable to use ROM manager?

Follow the instructions below to install CWM on your phone and then you can flash super user binaries to get root access.
If you have lost recovery then install pdanet on your computer.(It will also install Nexus S USB Drivers) then put your phone into fastboot mode by holding down both Volume Up and Power buttons together. When you are in fastboot mode connect your phone to your PC using USB cable.Download ADB and recovery you want to flash put it in your C:/recovery (Put adb and recovery image in this folder)
Then open cmd and type
1)CD C:/recovery
2)fastboot flash recovery recoveryname.img (replace recoveryname with actual file name of the recovery image).
You can download recovery from here
Or you can avoid all this and just use this

how to root nexus s ? from jb ? more infos ?
To root ANY nexus the process is the same. All that differs is the files used.
1. Unlock bootloader
2. Get the proper su zip on the devices storage. Either boot up and put it there or do it by mounting storage in step 3
3. Boot or flash custom recovery and flash your su.zip.
That's it. If you're already unlocked skip step one. Make sure you got the su.zip on your phone. Use fastboot to flash or boot recovery and boot into it. Flash the zip.
ive tried everything in this post, but i cant unlock or root. Im assuming the drivers are my problem because in Device Manager I can only install ACER ADB or Android Adb Interface.
In shabby's one-click, I get to the step where it says something like "select the unlock option on my phone", but in fastboot i only get 4 options and neither say "unlock"

Its old but still works. Go into fast boot and type in cmd fastboot oem unlock, its not an option in fadtboot. Don't use one clicks, learn the original way. You will be much better off in the future.

Hmmm.. You basically have 2 options here.
1. Get ADB working (it's not hard, try the Koush's Universal ADB driver)
2. Restore back to stock ROM, but you will need Fastboot working.
The thing is, if you can get Fastboot working, ADB should work too.. so...
If you need help with ADB, just ask..

[Q] 4.4.2 downgrade to 4.3 - backing up ROM before downgrade??

Hi
I have a standard motorola moto g 8gb unlocked phone - not tied to any uk network on 4.4.2 .
I wish to downgrade to 4.3 or change the rom to another rom.
Before i do this what is the easiest/simplest way to backup the ROM (o.s) which is not root'd ?
Or do I have to root the phone?
Also do I need to install drivers or not for the phone as Windows 7 sees the phone fine in explorer/my computer when the phone is turned on - i can drag drop files on there no problem
Thanks in advance.

a way to backup without root? Yep.
a way to backup without unlocking the bootloader? Nope.
You see, for everything you need the bootloader unlocked: rooting, flashing, etc...
so if you want to backup anything you first need to unlock the bootloader to flash a Custom Recovery and then do the backup and that can be done without rooting the phone, or touching the rom at all.
You will need the motorola drivers and adb:

Hi
ok made a bit of progress.
never thought it would be so much of a mission !
got the bootlocker unlocked..
now how do i install the clockwork mod or twrp app sorry for my ignorance. i have followed the links you've kindly posted me.
i am familiar with dos commands etc. - so that doesn't phase me.
i've downloaded the apps from a site both clockwork and twrp - .img files - do these have to be installed via command
prompt with fastboot to install them respectively whilst the phone is plugged in with usb cable in the bootloader phase?
are there not any "windows" apps that can install these apps?
Thanks in advance
You don't have to install both of them!

and also
You do not have to install both the recoveries, either cwm or twrp not both of them!
you said you unlocked bootloader, that means you have adb installed with fastboot
copy the .img file for twrp/cwm whichever you prefer to the folder where adb is installed
rename it to recovery.img
then turn off the phone and boot into bootloader and run
Code:
fastboot flash recovery recovery.img

Can I still install any recovery(CWM or TWRP) after I have forgotten my password?

My question is: Is there any way that i can install any custom recovery now, when I am locked out of my phone, so I can try Method 7 from this post . I have enabled USB debugging, but for some reason, my device is unauthorized from executing adb commands.
I have Xiaomi Redmi Note 3, and have forgotten its password. I have tried Method 2, 5 and 6 from this post, but to no avail.
I tried method 2 and 5 which requires ADB to be installed, but I was not able to access my phone. I have USB debugging enabled and my phone is not rooted. When I tried to run the following code:
Code:
adb devices
adb shell
it showed that my phone is unauthorized and error: device unauthorized This adb server's $ADB_VENDOR_KEYS is not set
Here's the screenshot:
When trying method 6, I had to change the path of ADB driver because the file I downloaded from the post, had its own ADB driver which clashed with my already installed ADB driver, but even after that, it again showed the above error. Here' the screenshot:
Finally I want to try method 7 from the above post, which requires custom recovery to be installed on the phone, is there any way now?
Though it seems now that the I have only one option left and that is to factory reset my phone, but if , there is any other way by which I can bypass my lock screen, please please please inform me.
Of course you can. Just boot your phone into fastboot and do "fastboot flash recovery <recovery image name>.IMG" and you'll flash it. And you can't access the adb because your screen is locked... This is how companies prevent phone hacking
So flash custom recovery, backup the /data , factory reset and after resetting restore the /data backup. And you're good to go. I suggest you using TWRP, because I use it and it never left me hanging Keep me updated.

OK... So first boot into fastboot. When you've done that, connect It to your pc with usb, download fastboot package from somewhere on xda(you'll find it).
Open command prompt "CD" to the directory where your fastboot is located in, put recovery image in the folder where fastboot.exe is and type "fastboot flash recovery <recovery file name>.IMG". I'm gonna update this answer in 2 days, when I get to my pc, so try to do it by these instructions, if something isn't working, comment and we'll resolve the problem. If something isn't clear, just ask. Keep me updated.

How to (root BLU Advance 5.0 HD)

Hi all
I'm looking to learn how to root a BLU Advance 5.0 HD phone (Marshmallow Android 6.0)
I'm newbie...
I already found a a blutwrp.img on https://bluroms.info/ website but this is the only thing I'm sure I have to use it.
About ADB I found the genuine google package (platform-tools-latest-windows) and the SR4-SuperSU-v2.78-SR4-20161115184928 package too.
I don't know if all this part are good for my phone...
Thanks for help...
I'm also looking for a root. I tried a few suggestions like Kingoroot but nothing has worked.

there is no automatic root for Marshmallow this is why I posted this thread ...

Yes you have to use the twrp recovery. Have you even flashed it? Using adb when the device is on, (make sure to enable usb debugging in settings and authorize your computer) run adb reboot bootloader and then make sure that fastboot recognizes your device and run fastboot oem unlock to unlock your bootloader. Unlocking your bootloader this way is the easiest and doesn't work all times. If it successfully unlocked your bootloader, just do fastboot flash recovery <recovery.img location> and then reboot into system and run adb reboot recovery, from there you can push the su zip or just adb sideload it. To push you do adb push <location to supersu.zip> /sdcard and then go to install and find the zip and flash it, to sideload it, go to advanced and hit sideload and type adb sideload <location to supersu zip>
If I helped, hit thanks Hope it works!

What's the codename for that device? Open up an adb shell, and report whatever comes before the $ sign
Hi
Thanks for help
There is many info here
please look at the file attached
I am strongly doubting that came before the $ sign. The attached file says [email protected] in the shell, indicating the codename to be ducati
its not rooted device
what is the command line to see the codename ?
In build.prop I can see :
ro.build.version codename = REL
ro.product.device=BLU_ADVANCE_5.0_HD
when I open a terminal I see:
[email protected]_ADVANCE_5.0_HD:/$
this is what you want ? So the codename is BLU_ADVANCE_5.0_HD
thanks
You don't even need to do anything or have root access, just open a terminal window and see what text is there, don't you're anything
[email protected]_ADVANCE_5.0_HD:/
this is what I see when I open a terminal windows

Huh, no offense to the creators but that is a pretty dumb name, anyway, you have fastboot and adb access right? I will try and have a check at the twrp image and see if I can verify that it is for the correct device and if you don't know how to flash it, a guide on that as well
---------- Post added at 09:30 PM ---------- Previous post was at 09:26 PM ----------
Update: The website seems genuine. Using an mtk flashing tool you can flash this file (youtube guide) and then using the supersu zip you've downloaded, use the methods I mentioned in my first post.
Good luck!
Yes its the device name. Thanks for your help I appreciate. The root process is often described on many website but there seems to be a doubt about a possible boot loop problem depending on the command executed... so I will follow your guide for sure.
I do not really understand.. You say I have to use MTK Flashing Tool+ADB + TWRP + SuperSU ... ?? I need two more university years ...

Should work with just using the mtk flashing tool to flash twrp then flash SuperSU. If it says something about bootloader being locked, just boot I to fastboot via adb and do fastboot oem unloc.

hey thank you so much for help I appreciate ! I understand that if i use adb to unlock the bootloader this will erase all my data right ? but if I use mtk flashing tool I get a chance to do a clean root to save my data right ?

It's fastboot to unlock bootloader, and I believe you're correct. Though, always make backups.
I managed to flash the blutwrp.img file but it put me into a boot loop. It would boot into Twrp, scroll information about being unable to mount anything and just boot loop.
same for me
