Not booting to recovery

what i did -->
1. Unlock bootloader
2. Flash cwm via "fastboot flash recovery recovery.zip"
3. Boot to recovery
4. Factory reset
5. Flash cm zip from sd card.
what i got -->
1. "E:Can't open /sdcard/cm.zip
(bad)
Installation aborted."
Then -->
1. Rebooted, copied again, booted to bootloader
2. selected recovery
Now -->
1. shows the android mascot with its lid open and "No command"
2. no cwm (where did it go ?!?!)
Everytime i flash recovery, it boots the first time (till the time I've not rebooted after flashing recovery) and still won't flash my zip file, and then the recovery won't show.
EDIT (FIXED)
WHAT WENT WRONG...
1. Was using CWM (When i was last active in android flashing, twrp was just another custom recovery, cwm was needed for cm)
2. When i did use TWRP, it was an older version, and did not work (did not even boot to recover, in fact)
3. When i did get twrp working, i used a bad cm.zip file (corrupted)

first mistake here is u used Flash cwm via "fastboot flash recovery recovery.zip" which is wrong u need to use .img after recovery but not zip so try once again and flash latest twrp as cwm support is ended

Thanks for the promt reply mate. Actually it was recovery. IMG only, not zip, i typed it wrong here otherwise the recovery wouldn't have loaded at all, as mentioned earlier. Moreover, I did try flashing twrp, but using twrp, I can't even get recovery to boot once (which does happen on cwm 6.0.4.7)
P.S - can it anyhow be related to bootloader ? I am on stock Lollipop. And device is dual sim (xt1033)

If u r on stock lollipop then u boot loader is already upgraded and its good for twrp recovery can u try flashing twrp v 2.8.6.0 and check it out using adb if it is already rooted then try flashing by flashify and let me know

Ok did that. When it booted to cwm (which is all i can manage to boot to, if at all) i selected root phone option. But it didn't root actually. Then i rooted successfully using cf auto root. Then used flashify to flash twrp image, and now when i select recovery from bootloader, it boots normally, not even showing the "no command" screen. (And yea, I'm pressing vol up to select, not power)
Update -- Ok flashed 2.8.6.0 and now boots to revovery (even after a restart) but still can't flash cm. Something pops on screen for a fraction of screen and then recovery reboots. It says "no md5 file found". Any chance of zip being corrupt ?
Update 2 -- Now my internal memory has stopped working :/ can't even take a screenshot, nor a photo. says memory full. Doesn't even copy file to memory when connected to pc. Although in recovery mode (twrp) , with usb mounted, it does copy.

weird did u flash normal recovery or gpe recovery ? U have to flash normal recovery and one more thing are u sure that its going into cwm recovery ?
May be the ROM is corrupted buddy download again and flash or try other Roms

Haha. After a hell lot of effort, i did get TWRP installed, and after breaking my head on why cm nightly won't install, i downloaded another one, and it installed fine. Now rocking CM 12.1 (4th device which I'm using on CM, and yet never had so much trouble getting it running..)

Unlock bootloader, flash twrp, vbeta, flash rom...ok but phone no boot!!!

Guys!!! what the hell!
i did everyting was written in here. Bootloader unlock, everything ok, flashed twrp, flash vbeta.img then flash any rom but the phone never boot! still go always and alwasy again to recovery!!!
What am i missing?

Format data in twrp.then reboot

I've done everything. Format everything ecc but nothing has changed...still no boot and recovery immediately.
I've tried to put the stock recovery again and it boots (i flashed of course via twpr the c.01 RUI ozip file before). I really can't understand.
I've tried to root the phone but again problem. I put the twrp recovery again (on the C.01 stock rom) then flashed magisk 20.1 or the latest. Everything ok, rebooted and....it says the boot img is corrupted, write or go to the service support! So i entered again in fastboot and flashed a new boot.img. No boot but can enter recovery. Put again the twrp, flashed stock rom again, put stock recovery, format data and now eveyrhing ok. Why so hard to even root???

Did you check format data on right bottom of twrp.this is not same as the wiping data

i made all format.
another curious stuff is. I put twrp, vbeta img . Reboot in twrp. ok. I reboot phone, go to RUI then i try to go again in recovery and .....no more twrp! but stock one! twrp has been replaced! why!!!!!?

Correct,Stock rom will replace twrp to stock recovery.but custom rom not changing recovery

I was doing the same mistake.
You must Format Data after flashing Rom and if on reboot to system it says Os not installed then first reboot to recovery.

uhm ok.
So basically - Flash twrp - go to twrp - flash rom (pixel experience for example) - format data - and then reboot to recovery again?? what's the point sorry

oh man i missed up the format stuff.
Thank you very much. I made it. After format data then i insalled the pixel experience rom via adb sideload now it started let's see hows it the modding rom world on this device!

I followed all those steps. My phone boots, stays on Lineage logo for 4-5 minutes and then it reboots back to orange recovery. Any idea? Thanks!

TWRP shows internal storage folders named as random letters.

I have a Redmi note 8 with MIUI 12 installed. Bootloader is unlocked and the phone is rooted.
When I try to flash TWRP recovery in fastboot mode using my PC, it successfully flashes and boots into the TWRP recovery. TWRP does not ask for any password for decrypting the files, and when I go to install>sdcard then the storage is all in random letters, completely unrecognizable.
I have tried a lot of tutorials on youtube but none of them worked. I tried flashing the latest version of TWRP, didn't work. I tried formatting all data and rebooting back into recovery mode, didn't work. (if you reboot to system after installing TWRP, the phone automatically deletes TWRP and the next time you open recovery mode you just get the default MI recovery, and you have to flash TWRP again to open TWRP recovery.) I tried almost everything on the internet but none of it worked. Is there any way I can make it ask for the decryption password? or have my files decrypted? I just need the TWRP for a one-time-use to install a custom ROM. I don't need it to be installed permanently, but no problem even if it does get installed permanently. I just want my custom ROM.
Please help

does that work?:
Boot into twrp, then
Code:
adb shell
twrp decrypt myPassword
(myPassword is your user password)

Okay, interessting. What's the exact error?
However, since you only want to use twrp to flash a custom OS, you could try to boot twrp (without flashing)
Code:
fastboot boot twrp.img
and then wipe data via twrp and then install your custom OS. You can use sideload which should be located under "advanced" I guess.
Code:
adb sideload myCustomOS.zip
EDIT: Don't boot out of twrp before sideloading, since your os should encrypt everything again after wiping which makes it unpossible for twrp to decrypt again (at least in your case, since it failed for some reason).
If you booted out of twrp, just wipe again and then sideload.

the correct and recommend way to install TWRP is
Flash TWRP
Erase userdata partition <~ it's important to do this as soon as possible since booting your device would just encrypt everything again
Format userdata partition
by doing this you would be able to access data partition files and folder would not be random letters.

Sorry for the late reply. Earlier i just gave up on installing the custom ROM and continued with my stock from. Today a tried again, installed TWRP and turns out it is not showing random letters now. its all regular storage. i didn't even do anything to decrypt it lol it just fixed itself. Now I will install the room myself. Thank you for your help though

Ah sh** here we go again. So i installed the custom rom successfully and everything worked fine, the TWRP too. but when I tried to flash a magisk patched image (the image that I used to root my phone in MIUI) then it got stuck in the boot screen. I had to flash the stock fastboot rom again.. And as expected from my piece of **** that xiaomi calls a phone, TWRP will show encrypted folders, and does not ask for a password. Same problem. Rooted my phone again, using the magisk root image, and it worked like usual, the phone rooted. Now i am stuck again in this bs. I guess I will wait for about 4-5 days and continue using the phone like normal. Maybe it will work again this time. I will try your method here first

Okay i tried wiping the data, cache and dalvik but it shows a huge essay of "error opening xxx/xxxx" in red text. Data wipe failed.
See you after like 4-5 days... hopefully

Update. I finally found a solution. It took literal hours of experimenting to find this.
-Flashed the fastboot ROM of the phone
-Rooted the phone by flashing magisk patched image
-Flashed Inception kernel via FK kernel manager
-Rebooting after flashing the kernel, It will get stuck in a black screen with no text whatsoever (probably a bootloop)
-Installed TWRP (This time TWRP does not show encrypted letters), Wiped all data, Transferred the custom ROM zip to the phone (while in TWRP) and flashing the rom
-The rom is flashed successfully. On the first reboot you get greeted with another bootloop. Fortunately the phone booted into TWRP. This time the folders are encrypted again.
-Successfully wiped the data (advanced>wipe data). No errors in data wiping this time.
-A fully working Corvus OS setup appears on rebooting.
I think the whole TWRP problem was fixed by the custom kernel. Anyways I am finally done with this now. You probably enjoyed seeing all this xD

I like that you keep trying and finding a solution, even though you had to invest hours to make it work!
Let's hope it will work if you update the OS though – I'd actually suggest a backup of all of your data before you do an update in the future, just to be safe!

tell me how to turn off a smartphone with a non-working sensor?

you can still use adb push command from pc to transfer files to your phone :
adb push "nameoffile" /sdcard
(place the file in your adb folder) I was able to root a phone that had this issue using this technique.

I think u should flash dm verity becoz when i flashed the rom and flashed dm verity it worked fine

Cannot fastboot into TWRP

Hey,
I updated already rooted phone with Oxygen updater (forgot that he will remove TWRP in auto install) and now can't get it to fastboot into TWRP with ADB. I tried several .img files but non worked. Every time it goes to Crash dump.
Did someone successfully fastbooted into one? Or the only solution is to go back and do it manually from OOS 10?
Thank you!

If you are on OOS 11 then use the attached file and try the below steps.
1. Reboot to Fastboot mode.
2. Use command : Fastboot boot boot.img (use attached TWRP alone)
3. Once rebooted to recovery mode Install recovery by Advanced -> Install Current TWRP . This should install the image automatically to your device.
Reboot your phone to system mode and then reboot it back to recovery mode later.
Hope the above helps.

TWRP is wonky on A11, for now.
If I'm not mistaken the TWRP provided by other poster will have issues with making and restoring backups.
If you are still rooted and looking for a backup/restore method, you might as well leave TWRP alone for now and simply maintain root through the Magisk app. If root was lost, then you can use the version provided here: https://forum.xda-developers.com/t/recovery-11-unofficial-teamwin-recovery-project.4306803/ which is likely what other user posted, to restore root and then wait for Google to release the full deets on A11 to hobby developers who can then make a new TWRP.

This worked for me to get back TWRP and root after upgrading. Thank you very much!

Twrp boot loop

I patched twrp img with magisk and then ran fastboot flash boot "patched file" in fastboot mode. Now, whenever and however I start my system I get only the twrp menu. My device is Lenovo tab 4 8(tb-8504f)

Re-flash tablet's Stock ROM to get rid off of all modifications you applied so far.

re flash the ROM. dont flash the magisk or twrp after it. you will be saved.
you can use twrp via adb boot twrpxx.img So flashing it not needed.
Magisk installation has now become trickier simply flashing via recovery won't work

hello thanks for replying. Could you provide me with the official rom. I've found one but not sure how reliable it is. I also in the twrp menu installed the patched twrp image from sd card to boot. After rebooting I again get the twrp menu but the file is not being show in sdcard anymore.
