Why cant I flash custom recovery on 4.3?

I downloaded the latest twrp recovery and put the file in my platform tools. (also renamed it to twrp.img) and I go into fastboot mode. Run cmd in my platform tools directory and type fastboot flash recovery twrp.img and I get this message twrp.img no error. Im following a youtube video and the guy does the same thing im doing and his works..

Does it do the same with CWM?

1. Is your bootloader unlocked?
Use "fastboot oem unlock" to unlock your phone's bootloader. Be warn that it will wipe everything if you do not use "fastboot format cache" afterwards.
2. Can you see your device after you run command "fastboot devices"?
Install the fastboot drivers, download google usb driver here: http://developer.android.com/sdk/win-usb.html

yes my bootloader is unlocked and when I run command 'fastboot devices' it works. Im really stumped..

is your kernel rooted? if yes use Recovery Tools (on play store).

I just flashed it last night without any problems but I renamed the file recovery.img. You sure you have version 2.6 for the Nexus 4? TWRP has different recoveries for each device.

Here's another thing to check. Make sure you didn't rename the file twrp.img.img as windows hides extensions by default. In my case when I renamed the file recovery I didn't have to add the extension .img as it was already there.

If you're rooted, try this method:
1. Boot to Android system.
2. Enable USB Debugging
3. Connect your phone with USB.
4. Run the command below:
Code:
adb push twrp.img /sdcard/twrp.img
adb shell
5. Next, get root permission and flash the recovery.
Code:
su
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
6. After confirming every steps, boot into recovery.
Code:
adb reboot recovery

Thanks guys i just used a toolkit and I have twrp for 4.3 now

[Q] ADB sideload & fastboot not working

Hi,I just installed android 4.4.3 from 4.4.2 rooted with kernel mat1x v13.5 with the following steps:
adb reboot bootloader
fastboot flash bootloader bootloader-mako-makoz30d.img
fastboot reboot-bootloader
fastboot flash radio radio-mako-m9615a-cefwmazm-2.0.1701.02.img
fastboot reboot-bootloader
fastboot flash system system.img
fastboot flash boot boot.img
fastboot format cache
fastboot reboot
Then installed CWM by:
adb reboot bootloader
fastboot flash recovery recovery-clockwork-touch-6.0.4.7.img
fastboot reboot-bootloader
and then I tried to go to recovery mode with:
Code:
fastboot reboot-bootloader
but the command line says:
Code:
<waiting for device>
. If I write:
Code:
fastboot devices
, nothing happens, but if I write:
Code:
adb devices
it does recognizes my phone.
Anyway I went to recovery mode with volume buttons (CWM is properly installed), went to sideload options, USB connected and typed:
Code:
adb sideload UPDATE-SuperSU-v1.99r3.zip
but it says:
Code:
error: device not found
While I'm in Recovery mode (in CWM) adb devices can't find any device.
SDK tools and platform-tools are just updated and PC is just rebooted.
EXTRA INFO: when i go out of CWM it says:
Code:
Root access is missing. Root device? THIS CANNOT BE UNDONE.
and options are
-no
-Yes - Root device (/system/xbin/su)
When I choose Yes it just starts with no problems.

Anything?

Try reboot the phone and then reboot to recovery and see if that works. If not, try TWRP recovery.

You mean turn off the phone and turn on to recovery? Because I've already done that as I mentioned in the first post.

Not sure but aren't recovery mode and fastboot mode different?
Can you manually boot into fastboot mode on your phone rather than using adb commands?

I just used fastboot to go into recovery with my pc because i'm lazy, I can do it with the mobile, but when i tried I discovered the <waiting for device> error. And I need to use adb coomands to sideload SuperSU. I think i can flash it from the phone, but it still bothers me the fact that there is something wrong, because I use my phone to test personals apks.

I assume the drivers load the first time you connect your phone. Does running the command prompt as an admin make a difference?

Ok, but ADB won't recognize my device when it's on CWM (CWM v6.0.4.7)
I realised that in "device manager" of Windows a yellow triangle appears on "Other devices" -> Nexus 4 (when im in Recovery)
and when I normally boot my phone it appears normally under "Android device" -> android composite adb interface

No clue?

Can't update

So my dad went out and bought a nakasig/tilapia it's running Android 4.2.1 and bootloader is 4.13. Having just updated my razor/flo via fastboot everything was setup and working. "adb reboot bootloader" reboots the nakasig/tilapia into fastboot mode and "fastboot devices" shows the nakasig/tilapia serial number. Every other fastboot command just hangs there and does nothing. "fastboot oem unlock" does not prompt me to unlock bootloader. "fastboot reboot" doesn't even reboot the tablet. I use Linux so I figured I would try Windows following the thread sticky'd in this forum http://forum.xda-developers.com/showthread.php?t=2175086 same problem adb works fastboot will list the device but can't do anything with it. "fastboot getvar all" did give me an error however "FAILED (command write failed (Unknown error))" all the other commands just hang there doing nothing saying nothing. Having tried Windows and Linux setups which I have used on my other Nexus devices without issue I am starting to think its an issue with the bootloader maybe I need some older version of fastboot.
Is there a way to flash bootloader from inside Android or Recovery? I can use Towelroot to root the tablet then flash TWRP from Android and boot into TWRP but I don't think you can flash a bootloader from there or unlock the bootloader can you?
Edit: according to http://forum.xda-developers.com/showthread.php?t=2068207 the nakasig/tilapia bootloader is encrypted so you can't flash or unlock it without fastboot.

OK so you have a 2013 N7 that does not have this problem, but your dad's 2012 does. Two different pieces of hardware.
Could it be a driver issue? Sometimes when the drivers are not talking to it correctly you get these flaky results. Different USB cable/port?
Theoretically there is a flash all command you can use to flash an update of the whole thing including the bootloader without it being unlocked. However if you are getting write errors then you should really be cautious because that could just fry it instead of fixing it.

No, AFAIK they're different drivers, and different devices often require a distinct driver install too.

Got any sources on that info?

WOW
weird! really weird!
I really don't know what the issue, the fact that it happens on Linux and on Windows makes me think to an hardware realted issue, unfortunately..
As long as I know adb and fastboot do not use exactly the same drivers, but you download and install them together, so it should n not be a problem, this one..
The only think I can suggest you atm is to try with Linux by logging in as superuser (su). On my slackware with my "normal" user adb works as usual, but if I try to use fastboot the terminal says me No permissions..
I hope someway your distro has the same issue, even if your fastboot devices success!
So login as superuser and try to use fastboot. If you do not install it in /bin partition you should have to locate its directory and then use
./fastboot devices
or any other command but with ./fastboot instead of fastboot..
hope it helps.. I really hope!!

For that matter, on a whim... when you open a command prompt in Windows to adb to your device, try running Command Prompt as an Administrator. Sometimes Windows is weird like that.

Please keep questions in the Q&A section. Development sections are for development only.

[SOLVED] Z1 not showing up in Linux ADB devices

hi,
trying to flash the breadcrust recovery using my linux pc, but the Z1 doesn't appear in the list of devices when running adb devices. Image attached. Normally I would get a request to accept the RSA key for a trusted pc when enabling usb debug. But I don't get this option.
- Adb tools are loaded and working on my linux laptop
- My nexus 7 responds to ADB devices and shows up ok
- tried on wifes windows laptop with adb/sdk tools loaded and no joy there too
- i have developer USB debug options enabled, i've tripple checked this
could it be the cable? I'm using the one which came with the phone, so that should be ok?!!
cheers
SOLUTION - I ran this One Plus Two script modified with the Z1 device ID and now I can see my device in adb devices and interact with it. I get the SHA screen to allow access and can run commands from linux terminal. YAY!
See the attachments for script.

I think it´s a driver fault. Did u install them in windows?

im using linux, i dont get any rsa pop up confirmation either!

But u said, that u tried ur wifes Windows notebook. Did u install the drivers there?

ADB doesn't work for me, too. I work around this problem by booting into recovery (simultaneously press Vol+ and Vol- and Power until phone vibrates) and choose "Boot to bootloader" from there. After rooting I installed "Power Toggles" from Play Store and use the toggle to reboot to recovery or bootloader.
By the way, when I boot into recovery, I'm able to ADB sideload. So I don't think there's a driver issue.

ok some progress.....
got the trusted device RSA screen to appear on my wifes windows pc. i could then run adb devices and see the device.
I could run adb reboot bootloader, but the device doesn't boot into fastboot, just reboots as normal!
I could also hold down up/down volume buttons and get into the bootloader, but again the device isn't picked by any fastboot oem checks for unlocking!!
arrrgh!!!

You'll have to add -i switch followed by the device ID to your fastboot command. I don't have it at hand, so just read the TWRP thread.

ok! Some progress...ish.
running "adb reboot bootloader"command in windows worked when I switched Cyanogen recovery updates off in developer options. The Z1 reboots into bootloader.
Running "fastboot -i 0x2b4c oem get-device-info" returns nothing just "....."
So I tried "fastboot -i 0x2b4c oem unlock" an error returns cannot unlock use command "fastboot -i 0x2b4c oem unlock-go" which works. The phone wipes data and reboots back into OS.
I re-enable the developer options and adb debug. and reboot into bootloader
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.
weird!

Your commands are simply wrong, thats why they don´t work.
It is:
fastboot -i 0x2b4c oem device-info
fastboot -i 0x2b4c oem unlock-go
Run "fastboot -i 0x2b4c flash recovery z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img" - some time stats are retunred and OKAY message. But when I boot into recovery it's still the cyanogen stock recovery. not TWRP.

Flashing does NOT work on the international version, you have to boot into it directly from fastboot.
fastboot -i 0x2b4c boot z1.twrp.2.8.7.0.By.Breadcrust-UPDATE3.img
Should be correct instead of the flash command.

What made the change? I was able to see the RSA screen only once, but after device restored to defaults I can't get it back. same drivers installed, and it appears in the device manager.

I honestly don't know, it just worked after many attempts. I read somewhere about USB 3 ports with Linux so might be the same for windows?

It's an USB 3.0 issue. Plug the phone into an USB 2.0 port, or an USB 2.0 hub plugged into an USB 3.0 port and it will magically start working. God knows why this is the case...
Ironically, fastboot works fine even on USB 3.0...

For to be able to boot (not flash) the TWRP recovery you shouldn't need to unlock bootloader. Am I right?

Okay, I have found out that it is impossible to boot from TWRP as log as the bootloader is locked. It just took me 2 hours to setup my phone again after unlock.

Have a look at this thread, I am going to give it a try later.

This did the trick on Linux (Ubuntu):
- run on terminal "sudo gedit ~/.android/adb_usb.ini"
- put "0x2b4c" in
- run on terminal "adb kill-server" and "adb start-server"
And run the fastboot commands with "sudo".

Fastboot mode issue in MiA1

Hi.
Recently I decided to flash lineage os 15.1 on my MiA1
For that I have downgrade to Android nougat.
After downgrading I booted my device.
After setting up device I booted device in fastboot mode to follow further steps like flashing TWRP and all but the problem is my device goes in fastboot mode and it is not identified by abd and after that it is automatically getting restarted and is not holding in fastboot mode.
Please help??

Odd issue. What are you using to flash? If you are using XiaoMiFlash.exe, you'll want to try the (THIS WILL REMOVE ALL YOUR DATA) "clean all" option. Please note that this removes all your data.

I have used MiFlash tool for this and now My device automatically reboot from fastboot mode so I am not able to use adb as well to flash rom or twrp also Now MiFlash tool is not recognising the device.

It should boot if you've fully flashed it and cleaned the user data partition. If it still isn't, you'll want to wait for other members with more experience in bricks to chime in.

My device is booting up without any problems.
But the problem is bootloader is still unlocked. So i am not able to update via OTA.
And as the device does not holds in fastboot mode so I am not able to do other flash work.
Is there any way I can share a video of my problem with you?

Oh. If it's booting up fine, then you shouldn't be worried too much.
If it keeps restarting in Fastboot mode, it could be a driver issue which is preventing your PC from recognizing your device and vice versa. I'm on Windows 10 which installs drivers automatically so I've never had experience with it.

I think that's expected behavior? If it doesn't recognize itself being connected to a device, it'll exit fastboot mode.
I think you need to connect it to the USB cable and into your PC for it to not restart/power off.

wait.. what exacly did you do when you booted into fastboot? did you type "adb devices" or "fastboot devices"? also, try rebooting into fastboot mode by typing "adb reboot bootloader" in cmd, with your phone plugged into your pc, and with the proper platform-tools installed. it shouldn't really go away from fastboot mode like that.

Hy man, I know basic of adb and I use cmd "adb devices"
My device is recognised when it is on.
I can also give various cmd like boot in recovery or fastboot mode or reboot and the device follow the instructions.
Please see the video that I've shared.
Once fastboot mode is on the device is automatically restarted in about 10 to 15 sec and within this time MiFlash tool or adb cmd prompt bot does not recognise my device.
I have tried to flash OTA via adb side load but it is showing error.
Help me with your input!

Your device doesn't get detected in your CMD prompt when it's in fastboot AND you type "fastboot devices"?
If it doesnt then you might have flashed something incorrectly.
Also, make sure to have your android drivers up to date in your pc. It's very, very likely that you don't have them installed on your PC, or they are outdated. See this: https://developer.android.com/studio/run/oem-usb.html

I have faced this issue. Yesterday i dirty flashed a custom rom. but i forgot how to dirty flash. i just simply flashed the rom and restarted the phone. it was mandatory to flash custom recovery and gapps after flashing a rom dirtily or normally. but i didn't. After the reboot completed, i remembered that i didn't flashed the twrp and gapps. So, i go back recovery mod, guessed i could flash twrp now. But i didn't see any custom recovery on my phone. But the phone boots, and i can use the phone. Still, i'm on that phone, while i'm typing this comment. i didn't lost my data cause i flashed dirtily. But the problem is, as i didn't flashed gapps or magisk (for root access), now i can't use google apps like, play store, and more. As i don't have root access on my phone so, i can't run flasify, to flash custom recovery. neither i can run other apps that need root. As i didn't flash custom recovery, now i can't flash gapps, magisk and whatever that needs a custom recovery.
I told some rom porter about the matter. They told me to flash stock rom. So, i was trying to flash stock rom. but flashing stock rom requires a fastboot mode. But my fastboot logo doesn't appear and it's blank. I told this to a rom porter. But he said, He doesn't know about that and he can't help.
