Tablet on Boot loop - Shield Tablet Q&A, Help & Troubleshooting

Help pls i just installed CWM on my Tablet using this code
fastboot flash recovery recovery.img
then when i was about to test it i accidentally entered this code
fastboot flash boot recovery.img but i was supposed to enter fastboot boot recovery.img
now i can boot to CWM but everytime i boot it goes straight to CWM not to the system
so i tried flashing the boot-root.img using this code again fastboot flash boot boot-root.img (the boot-root.img was provide by superPichu before)
and now my tablet keeps on rebooting =( i can still enter fastboot and CWM any help pls?

What rom was originally on the tablet? You'll have to procure the boot image from that rom and flash it. That or just reinstall the entire rom ...either from fastboot or from cwm. Your data should be intact.

hello i have a big trouble with my htc one s, is a S4 variant and i try to boot normally but is always boot on the cwm 5.8! i reboot and is return to cwm! help me i try everything
Sounds like no ROM
From the sounds of it, it doesn't seem like you have a ROM installed.
A few things to remember when flashing new ROM's:
-Try not to ever flash dirty* (without wiping data, cache, dalvic cache, and system)
-ONLY wipe the system if you have another ROM loaded onto the internal SD card and ready to flash
-Make sure said ROM is COMPATIBLE with your phone. (Device model, in our case HBOOT [2.15, 2.16 have their differences]
-Try to update to the latest Recovery when flashing, unless stated otherwise in the ROM's OP. THEY WILL TELL YOU WHAT YOU NEED.
There is plenty more, but for your issue these may help.
Update your recovery through FASTBOOT and then use the MOUNT option to mount your SD card and add a new [compatible] ROM and try to flash it. (and if it has GAPPs, flash that AFTER you flash the ROM)
i dont flash anyrom, i just flash the recovery and write this command line "fastboot flash boot recovery*.img" (just a cut of the .img of the recovery) and after that, is allways reboot in recovery mode

Code:
fastboot flash boot recovery.img
flashes recovery to boot sector. That's why your device boots into recovery every time. You should use
Code:
fastboot flash recovery recovery.img
to flash recovey correctly, unzip boot.img from your rom's zip and flash it with
Code:
fastboot flash boot boot.img
to be able to boot into your rom

[Q] Recovery not working

I just received my new nexus 5.
This is what i did:
1. enabled adb in settings.
2. booted in fastboot mode and launched the "fastboot oem unlock" command
3. rebooted end re-enabled adb settings
4. booted in fastboot mode with "reboot bootloader"
5. flashed latest CWM recovery with "flastboot flash recovery ..."
now my recovery is empty with a scary red triangle in the middle. If i reboot the phone all works normally.
I can even flash other recovery images through the fastboot mode but nothing changes.
What can i do now?
Thanks
Red triangle is stock recovery. You didn't flash other recovery.
Not sure what commands you're using for flashing but I wrote a detailed adb and fastboot thread which you can get to via my signature.

what command are you using to flash other recoveries?
i renamed the downloaded file as recovery.img then typed "fastboot flash recovery recovery.img"
it said transferring and flashing done

Download it again. In fact you should download TWRP not cwm. Also please read the thread I asked you to read.

So, i've tried with CWM, TWRP, with different cables, with different computers, it just seems that my recovery is not writable.
Have i received a faulty phone?
Now i'll try to flash stock recovery than again TWRP.
If it doesn't work i'll flash the whole factory image...
i dont have any other idea
Flashing stock recovery didn't work.
Flashing everything stock worked fine. I think something in the bootloader messed up
Backup everything then flash userdata.img with fastboot while in bootloader.

You didn't. You said "flashing everything stock worked fine" with no mention of "TWRP". ;]

tablet only boots fastboot, what are my options?

i tried updating from cromni-kk to zombipop. i wanted to try rom2sd so i formatted sd w/ aparted on my tablet then flashed the rom. aftter it flashed i rebooted. it initiated the boot process but when it tried to boot into os it rebooted and went to recovery (twrp). instead of twpr opening all i get there is the twrp splash screen and it keeps flashing. i can get into fastboot so are there any recovery options i can use from there?

If you want to try ROM2SD then you have to flash special TWRP. If you want to come back you have to flush normal TWRP. As you are able to fastboot, that should be no problem.

would you mind elaborating a bit?
i've managed to figure out how to get adb working on the pc, but beyond that i'm a little lost. could you point to to where i get my recovery file and where it goes when i run you rcommand?
nevermind, sorted. thanks for the help.

I kinda wiped away my phone's OS and I'm not sure how to fix it, help?

Hi, so I was messing with the recovery mode on my phone when trying to install a new rom and somehow ended up wiping the os. I actually managed to install the rom, but I don't know what possessed me to start tapping random buttons and that's how it got messed up. Now my phone is stuck in fastboot mode and I don't know how to get it back to normal. Any advice on how would be a great help, thanks in advance.

Fastboot flash recovery, then try using adb commands to boot into recovery and flash your ROM again. Or, try extracting the system.img from your ROM, place the system.img(rename the file to system.img if it is labeled by another name) in your fastboot folder on PC, open a terminal and flash the system.img via fastboot using the following command:
fastboot flash system system.img

How To Guide Xiaomi 12S Ultra TWRP(unofficial)

12S Ultra unofficial TWRP - link MEGA
Credit - UnofficialTWRP
They released TWRP under 12S Pro, but the code name is Thor which stands for 12S Ultra, and after flashing, I do confirm this is for 12S Ultra.
now they have a proper 12S Ultra section!
Download the image and rename as recovery.img for simplicity.
fastboot boot recovery.img (or full file name)
in TWRP, go to "Advanced" and "flash this twrp."
edit: the recovery image file is too large to be flashed directly via fastboot, so you need to boot first then flash using twrp!
edit2: backup and restore function may not be working properly on this version of twrp! I get boot loops everytime I do a full system backup and full restore after bricking the device, especially on the data partition. Clean installing rom then restoring data only still get boot loops. so use it with caution.
I suggest you to use 3rd party backup apps to do backups on apps and data, and stick to the flashing and other functions only for twrp.

No. You must type fastboot flash boot recovey. img

No I'm pretty sure it's:
fastboot flash recovery twrp.img
However my question was why the method outlined by @Nabicook vs this method. Is it because of the dual partition?
GodKingKnight said:

Because not only it is the method unofficialtwrp suggested, but also the size of the recovery img file is too large to be flashed via fastboot.
I already tried
fastboot flash recovery recovery.img
fastboot flash recovery_a recovery.img
and so on, but all failed.
only way to properly install this version of twrp is to boot first then let twrp to install itself to both a/b partitions.
Hi!
I'm following your guide...and after uploading recovery nothing happens
rebooting into recovery through ADB or just using buttons...still sends me into fastboot mode
What can I do?

are you sure you did
fastboot boot (your recovery file name).img
it should automatically boot into twrp without touching anything from fastboot mode.
then install twrp through the advanced option in twrp

Still having issues:
After flashing twrp + magisk, reboot sends me into fastboot mode ..
As I get it, previously I've messed up with boot image, flashing recovery into that partition
So question is:
Do I need to reflash stock boot.img (need help with getting it, stock recovery rom is packed into .bin and I'm unable to extract boot image
Or can I simply reflash stock ROM (in recovery or fastboot mode?)
*my phone is unlocked already

yeah you can try flashing stock boot img, and if that doesnt work, you can download fastboot rom and flash stock rom using flash all without wiping data(there is .bat file that says something like install without formatting).
That will fix any kind of brick issues of xiaomi device, and you just redo the twrp part.
