Locked state and no access to settings to enable ADB - Nexus 7 Q&A, Help & Troubleshooting

Hi,
Original ROM got corrupted of some sort and I can no longer access settings to enable developers options / ADB
Device is locked. Original recovery is non existing....
So I cant recover, enable ADB or fastboot.
What are my options please?

Ok, I got it going. Here were my steps:
PRE:
Download twrp-3.3.1-0-grouper.img from Download twrp-3.3.1-0-grouper.img
1. Boot into fastboot (volume down + power).
2. From terminal:
Code:
fastboot devices
to confirm it is recognised.
2. From terminal:
Code:
fastboot oem unlock
and confirm on Nexus.
3. From terminal:
Code:
fastboot boot twrp-3.3.1-0-grouper.img
.
4. How to fix unable to mount data internal storage 0mb in twrp permanently : | XDA Developers Forums (xda-developers.com) .
5. Deep format from TWRP (advanced - clear absolutely everything).
6. Job done.
Helpful links:
Semi-bricked??
Weird: I was just using it normally, it switched off and now it stays stuck on the Google logo; when entering recovery mode, I get TWRP"s splash screen and it stays there, so I cannot even recover. Suggestions please?? Note 1: I'm pretty bad...

[Q] Nexus 10 will not boot after unlocking bootloader

Hello all,
I am trying to install Cyanogenmod on my Nexus 10. I followed the instructions on the Cyanogenmod wiki (I can't link to them as a new user). I got as far as these instructions to unlock the device:
Enable USB debugging on the device.
Connect the device to the computer through USB.
From a terminal on a computer, type the following to boot the device into fastboot mode:
Code:
$ adb reboot bootloader
From the same terminal, type the following command to unlock the bootloader (under Linux, you must be root):
Code:
$ fastboot oem unlock
A disclaimer will display on the device that must be accepted. Use the volume keys to cycle through the options. Pressing the power button should confirm your selection.
If the device doesn't automatically reboot, reboot it from the menu. It should now be unlocked. You can confirm this is the case if you see an unlocked icon at the bottom of the Google boot screen during reboots.
However, the device never rebooted. It just shows the glowy nexus X logo indefinitely. If I reboot to the bootloader, I get options for recovery mode, however the device does not show up on fastboot or adb from my computer in recovery mode, so I don't know what to do.
I am new to the world of unlocking and custom roms and whatnot, and am worried that I just bricked my tablet . Thanks for reading.
OK, I found the answer searching online. A video on youtube explains it. The forum won't let me link the video, but the youtube id is T1Se7Hr9Cww. Put that after the "v=" in a youtube URL and you'll get there.
explains how to fix it. Evidently unlocking the boot loader doesn't reset the device, but the device must be reset to continue. So you need to do mash all the buttons in recovery mode to bring up a menu to delete your stuff.

Some Help With TWRP and Bootloader Please

Hey guys. I've tried everything, and I'm stuck. Never had so much trouble doing something so basic. No idea where it's going wrong.
Here's the basic timeline:
1. Bought phone
2. Unlocked/rooted/flashed TWRP
3. Tried CM13 for a bit, clean flash +supersu
4. Tried Exodus for a bit, clean flash + supersu
5. Tried community build of 3.0.1, clean flash +supersu
6. Wanted OTA update, so dirty flashed community build to remote root, OTA update ended up replacing TWRP with stock recovery
7. I want to go back to exodus, and can't for the life of me get TWRP back on
Here's what I've tried:
1. Basic steps on any website to download adb drivers etc.
2. Tool box from XDA
3. Factory reset then try all of the above again
Issues:
When I try to fastboot flash recovery [file] I get error: cannot load 'recovery.img' I've tried renaming it to twrp.img as I've seen suggested in some places, no help. I've ensured that the image file is in the same folder as the command prompt. I have used the Grarak TWRP file as well as 3.0.2 and 2.8.7 as suggested on some other sites.
Things I'm noticing:
When I try the fastboot devices command, it only recognizes my device when in fastboot mode, but not when loaded normally. In fastboot mode I can issue commands to reboot, get info, etc. but once loaded it's all gone.
I haven't seen that prompt that comes up to authorize a computer RSA code for USB debugging (yes, USB debugging is enabled in developer options, and yes, I have tried changing the USB settings from charging, to MTP, PTP, even MIDI.)
When I use the device-info prompt I get the following results:
Device Tampered: false
Device Unlocked: true
Device is_verified: false
Charge screen enabled: false
Display panel:
console_locked: 1
exec_console_unconsole: 0
Any and all suggestions would be greatly appreciated!
Hi, Here's what i believe you need to do. If you have the correct twrp recovery img file and all you need is to just flash it to get custom recovery in order to continue enjoying your custom roms, then this will fix your problem.
1. make sure you have all the necessary adb, fastboot drivers installed and that if you run the command 'fastboot devices' fastboot can see your Oneplus device.
2. if fastboot can see your oneplus device, then worry not. use the following command to flash your custom twrp recovery.
3. Rename your recovery file to just recovery nothing else attached.
4. boot your phone into fastboot, open the folder where you have your recovery file and hold down the shift key and rightclick anywhere in the folder and select the option that says 'Open command Window Here'
5. this will load fastboot. after fast boot loads, enter the following commands :
fastboot devices (this will display your device, once your device is showing, then worry not)
6. the next command is to flash your custom recovery image. so u need to enter exactly the following :
fastboot flash recovery recovery.img (this will then flash your custom recovery. make sure you name it just recovery)
7. after flashing your recovery, enter : fastboot boot recovery.img (this will boot you into twrp recovery mode)
let me know if this helps. Cheers!!

In the developer options, select "OEM unlock" it will ask for password / PIN / pattern and once activated, we look for "Debugging via USB" and we activate it also, then proceed to turn off the phone)
3) Turn on the phone by pressing Vol down + Power button together for 5 seconds until we get a screen like this:
4) Open adb command window and type:
Code:
fastboot devices
If your device appears on the command window you can continue with the guide, if your phone is not listed, install the Moto drivers correctly and verify if adb is working or not...
5) In the same adb command window type:
Code:
fastboot oem get_unlock_data
You will see numbers displayed like this, copy the code and paste it into notepad..Now eliminate the paragraph break so that there is only one line without spaces… Copy the entire code & login into your Moto account…Now paste the code on the same Moto webpage which was given above…

7) After re-entering the command, you will bootloader unlocked message
_______________________________________
3) Flashing TWRP and Rooting via TWRP
​
Note: Custom recovery (TWRP) woks only after unlocking your bootloader… Before flashing this recovery unlock your bootloader and enable USB debugging…
​
Files required:
1) Motorola drivers (https://motorola-global-portal.custh...ail/a_id/88481)
2) ADB installed (https://forum.xda-developers.com/sho....php?t=2317790) or (http://forum.xda-developers.com/show...8#post48915118)

2) In the adb command window type
Code:
fastboot flash recovery recovery.img
3) After executing the command, disconnect your phone & with the volume + or volume keys - we move until it says "Recovery Mode" . Press the power button to confirm the entry to the recovery.
4) Once you enter the recovery, select the right button & a menu to choose the language is displayed, it only brings Chinese and English so we will put it in English to know what to do.
5) We will see that it asks for a password, it is the same password that you put to encrypt the phone at the beginning when they set up the factory phone and always asks them to turn on the phone, it can be a password / PIN / pattern
6) Once the password has been entered, the recovery main menu will appear, we will go to "Advanced" and then "Install SU", it will ask if we want to root the phone, we accept by sliding and we wait for it to do the process. Then we give in "Reboot System" to restart and the phone will ignite with root
_______________________________________
4) Backing up / Restoring EFS (IMEI)
Note: This works only if you have TWRP recovery... Please backup your EFS using the method below before flashing any rom including stock rom
​
Backing up EFS (IMEI):
Method:
1) Boot the phone into TWRP recovery
2) Go to "Backup"
3) Select EFS
4) Create backup by sliding
5) Once finished, restart the phone
6) After restarting the phone, copy the TWRP folder from the internal memory to the SD, DO NOT CUT and PASTE, just copy with a file browser. Later from the SD card can be copied to the PC
Restoring lost IMEI / EFS:
Method:
1) Boot the phone into TWRP recovery
2) Go to "Restore"
3) Select folder (location where you have kept a backup of your EFS)
4) Restore by sliding
5) Wipe cache and dalvik and start phone normally
_______________________________________
5) Restoring original Boot Logo after unlocking bootloader
​
PS: This is used to remove unlocked bootloader warning when the phone is turned on (the black screen with letters)
Credit goes to : G4liant
Files needed:
1) Motorola drivers (https://motorola-global-portal.custh...ail/a_id/88481)

When you turn it on, we will notice that we have the original motorola boot logo again and that the previous warning does not appear even when the bootloader of our device is unlocked
_______________________________________​
6) Installing Xposed Framework
​
Files needed:
1) [FONT=&quot]Have TWRP installed (If not installed refer to section #3 on this thread)

Optional: Download latest Xposed un-installer but ARM 32 version not ARM 64 (http://dl-xda.xposed.info/framework/uninstaller/ )[/FONT]
Method:
1) Copy Xposed installation .zip, Xposed uninstaller (optional) and the Xposed APK to the internal memory (the TWRP does not mount the external SD so do not bother copying it to the External Memory)
2) Install the Xposed APK but DO NOT open it.
3) Enter recovery mode and open TWRP, Choose language and enter password to decrypt your device
4) Once the password is entered, the main recovery menu will appear, select "Install" and a file manager will appear, we will navigate the file down and look for the Xposed installer .zip, something like this:
5) Select the Xposed installer .zip and it will open a zip installer, slide to accept the flash of the .zip and wait for the process to finish. Then we give in "Wipe Dalvik / cache" and then to "Reboot System" to reboot and the phone will light up with Xposed already working.

Nicely work
Really nice thread. Just one thing...
Could you credit me for the modified logo.bin?
https://forum.xda-developers.com/showpost.php?p=69273602&postcount=37
Can I flash logo.bin zip in twrp?
Nope, has to be unzipped and flashed in fastboot, which shouldn't make much of a difference, as it has only to be done once. No need for reflashing after switching your custom rom.

Need help fixing my bricked phone

Hey Guys,
I have a redmi 3s prime and i tried to install lineage os on it, during the process i accidentaly flashed twrp over both the recovery and the boot. Now i cannot get into the recovery (and fastboot) unless i flash it over boot before rebooting my phone. After that i AM able to flash an new rom but it seems to always have wifi issues.
atm i am trying to flash the xiaomi developers global rom to see if it makes any difference. My main goal is to flash TWRP and a curstom rom (linage or resurrectionremix).
Can anyone help me?
Thanks alot!
Update #1
The flashing of the global developer rom worked and the wifi seems to work aswell, i will try to boot into fastboot and recovery.
Update #2
Its seems i am able to boot into fastboot and recovery again
Update #3
Following a tutorial for flashing TWRP and a custom rom but cant se2 anyone help me here?:
Code:
>>> Check then next step to root :
- launch minimal adb tool (previously installed)
- type : adb devices (to list phone connected) it will appear "unauthorized"
- on the phone : accept the computer
- re type : adb devices
it has changed in "authorized"
- type : adb reboot bootloader
it will go in fastboot mode (the same that power + vol down)
- type : fastboot devices
your phone will appear as in adb mode (unless the bad signed driver is choosen in win10 ; i won't repeat it again)
- type (optional) : fastboot oem device-info (to verify if bootloader is locked or unlocked)
now, we go to root
- type : fastboot boot twrp.img (if it is your renamed twrp copied in the minimal adb folder)
link for TWRP guide at the end if needed
!!! it will boot temporary in this recovery but it will keep your original recovery !!!
> allow to modify system (don't keep the "read only" if you want to root or flash recovery later)
go to settings to set date, hours, language, set custom options...
My optional advices :
- save your EFS & persist partitions or all whole partitions (except cache) to make a backup
- export this backup in computer or SD card in case of future problem
(EFS, persist are usefull to save and restore your IMEI in particular)
- you can flash directly TWRP with fastboot command : fastboot flash recovery twrp.img
>>> Root :
Now flash DM-verity patch, then superSU.zip to root and accept to wipe dalvik/cache after, finally reboot !
Device is rooted ! and you have kept the original recovery.
the reboot is quite long like rom update (because of cache rebuild)
sometimes, parts of theme are lost after rooting : just restore your theme
some devices don't need DM-verity patch as explained upper
superSU app shows "systemless root" from android 6+, it is normal, read below
>>> Change the Recovery by TWRP (optional) :
Now you are rooted, you have 2 methods :
- Install one TWRP app with googleplay and flash recovery through app on rooted device.
New official app in development (flash/backup .img & .tar)
- OR reboot in fastboot mode (with TWRP app method or power+vol- method or adb reboot recovery method)
in fastboot mode, and type commands :
fastboot devices
fastboot flash recovery twrp.img
(be sure your twrp.img is unlocked and correctly copied/renamed in minimal adb folder)
Now, long press power to turn OFF phone
power + vol+ (release power at vibration) to enter in TWRP or by TWRP app or Updater app or under Windows with minimal adb reboot recovery command
Note for devices with DM-verity : flashing TWRP needs to have patched system with DM-verity patch before because you will modify system most of time - generally, you don't need to patch again because you have ever done it in previous steps - in case of bootloop : go to fastboot mode, boot in TWRP with command and patch it.
Chainfire has recently modified superSU for android 6+ devices with DM-verity to install root without modify the system : it's called "systemless root". When you flash superSU.zip, it detects automatically android version, cleans old files and installs with appropriate method. Maybe no need to patch boot in this case with DM patch.

I seems that the right command is "fastboot flash recovery twrp.img"
Unless you wanna install the recovery onto the kernel partition.
@OP: The correct command to flash the recovery is
fastboot flash recovery twrp.img
Please correct it in your post.

Because the instruction in first post is incorrect, after you flashed recovery you also need to use this command: "fastboot boot recovery_image_name.img"
This is needed only to boot into TWRP for first time, if you intend on flashing custom ROM's then Format DATA,reboot to recovery again and you can use it normal.
