Hi
I tried to flash the knock code for open-devices over a rooted stock rom with custom recovery - so everytime I boot it automatically boots into custom recovery.
How do I enter download-mode to unbrick it using the offline-fix for the LG R&D Test tool? Holding volume up while plugging in the cable boots into TWRP and holding volume up+power also boots to TWRP..
Everything I try boots into TWRP even if it should boot to Download-Mode
SOLVED: (my problem was wrong searches within XDA and Google - "no boot after flashing knock code" isn't "LG G2 download mode doesn't working")
1. Open in TWRP:
Advanced - Terminal - Select / as folder - go to terminal
2. Enter
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
and hit "GO"
3. Enter
Code:
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
and hit "GO"
4. Back to main menu in TWRP - hit reboot -> System
now worked...

I had the stock CWM from rom manager and I tried reinstalling team rouge. Now everytime i hit reboot, it reboots to recovery the rom manager version. Any advice?
Ive also tried a hard shutdown, it powers up into recovery.
Well I solved it. I rebooted it held the vol down button and instead of telling it to go into recovery i let it sit till my system booted normal. Good job me, I wish i could add thanks to myself
Go here and see how to fix it.

If not you'll have to go through the cold boot process with the buttons every time
I also had this problem few days ago. But, I deal with there steps:
1. press power button and volume down
2. seeing the ASUS logo, don't press volume up and wait for few seconds
3. the TF will turn to a screen and ask you whether to wipe or cold boot
4. Cold boot it and the TF should boot regularly
and try these steps to install new recovery:
1. after booting, use cmd to access adb shell
2. type: echo boot | dd of=/dev/block/mmcblk0p3 bs=1 seek=0
3. place your new recovery in sdcard
4. flash it through rom manager
5. wait for flashing and rebooting. the frickin' recovery should be gone
Without adb

Worked for me from shell too. Just switched off the device and cold booted after entering the above command (echo boot .... ) to bypass the damaged 5.5.0.4 recovery.

If you've used TWRP and can't get out of a repeated loop of recovery boots, follow the instructions at TeamWin's page:
http://teamw.in/project/twrp2/79
Specifically:
- If your device is always booting TWRP run:
Code:
adb shell "idme bootmode 4000"
- If you still can't get out of booting TWRP, first run:
Code:
adb shell "idme bootmode 4002"
reboot your device, then run:
Code:
adb shell "idme bootmode 4000"
reboot again and you should be out of your bootloop
(PS to Mods - Seen so many asking this, and if it belongs in General, sorryandthanks for moving if you do !)
Where or how do you run this?

This worked for me (Galaxy A7 SM-700FD) 5.0.2
-u need to remove TWRP recovery from your phone totally.
-i Flashed stock android recovery (well i got it by experimenting, as i rooted my phone again by ODIN it replaced the TWRP recovery with android recovery(turn off Auto-Reboot))
-you will be stuck in boot loop mode (stuck with the logo- good news is you are out of TWRP recovery boot loop)
-you have to get to boot loader anyhow (either by adb commands or vol down, home, Power key pressed all together)
-Flash TWRP recovery again using ODIN (turn of Auto-Reboot)
-hold the power key which will try to restart the phone.
-still it is boot loop mode.
-enter Boot loader (pressing Power key, Volume down, home- all three keys together or by adb commands)
-enter TWRP recovery (pressing Power key, Volume up, Home key- all three keys together or by adb commands)
-Restore your backup
-and you are good to go

You could try asking in the Google Pixel forum?
- If your device is always booting TWRP run:
Code:
adb shell "idme bootmode 4000"
How should I type this command in TWRP Terminal Command?
Please, advice.
Hello I rooted my tablet and try to do a system backup (filed cause no memory in sd) now I can't get out TWRP
In my case, EMMC rom was stuck in read-only mode. I ordered a new one, changed it and completely updated my phone via Flashtool.
thanks you too man
Easiest solution for a700fd is... reflash the same twrp from odin(turn off auto reboot) and simply reboot.... worked for me... and please someone tell me that this phone jumps again after some time or i flash something(not always) in twrp or recovery bootloop...????
I just used this method
""Enter the following commands to flash TWRP Recovery on your tablet:
adb reboot bootloader
fastboot flash recovery openrecovery-twrp-2.2.1-grouper.img
TWRP Recovery will then be flashed on your Nexus 7.
You will also get a “Finish/Okay” message at the command prompt. Type this command to reboot your tablet:
fastboot reboot
To enter TWRP Recovery, switch off your tablet. Press and hold the Volume Up, Volume Down, and Power buttons together.""
to install twrp on my nexus 7(rooted and unlocked with stock ROM).
It went well but when i try to boot it into recovery mode from bootloader, its just stuck a the google symbol screen.
I tried an alternative, using goo manager. when i reboot it using goomanager, it goes into twrp but not when i manually reboot the device and go into bootloader mode... Please help!!!!!
There's a bug in the boot loader that requires you to be plugged into a computer to access recovery.

as previously mentioned, there is a bug.
I can boot into TWRP via hold Power button -> Reboot -> Recovery, if your ROM [stock rom?] does not have this, download ROM Toolbox on Play Store, and select "Rebooter" on the bottom, and "Reboot recovery"
Or I think you can use Terminal Emulator, and type
# su
# reboot recovery
that should work too..
or you can just plug it into a computer
Thanks a butt load!!!!!!!!!!
I also think goomanager or rom manager has a bug that it wont let me power on my tablet unless i hold the power button down for 10 seconds. I remove those apps then all is fine.

Ok guys I accidentally took the OTA today stupidly, on my rooted phone with twrp, and it rebooted to recovery to install the OTA and now, it will not boot out of TWRP no matter what reboot option I choose.
Is there an easy fix for this????
I have ADB and all of that stuff.
Solved:
You go TWRP -> Terminal command -> select and type.....
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
then hit enter
type
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
then hit enter and reboot.
i dont know what happended but after flasing my mobile is rebooting into recovery mode only i dont know what happended, plz help me
solved
i followed a youtube link thanks mate..
Go to advance, then go to Terminal and write down these codes one-by-one.
1. Code (Text):
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/fota
Now press enter, and write down another code.
2. Code (Text):
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/misc
Press enter again!
Then go to main menu, go to Reboot and hit System.
