I had a mostly-stock Nexus 7 running 4.1.1 - unlocked, rooted, TWRP installed, but no major /system changes. When the update came in, I figured "what the heck, I'll just see if it applies - worst case I lose root and my recovery console, but it's a nexus, it's easy to get those back". I applied the update, and it worked! It applied and rebooted, worked fine - but it did lose root and recovery as I expected.
So I tried to get recovery back. It won't come back. Here are the ways I tried:
Hold down VolUp+VolDown+Power to get to fastboot mode. Ran
Code:
fastboot boot recovery.img
(using a number of different copies of both clockwork and TWRP recovery). Each time, the screen went black, google logo came up, but then it booted to AndroidOS
Tried to do
Code:
fastboot flash recovery recovery.img
The flash seemed to look like it did fine, but when I selected "Boot Recovery", it didn't. It booted Android OS
I can get into STOCK recovery using the normal method of selecting it from the menu just fine.
Stock recovery doesn't have ADB running. Fastboot mode doesn't have adb running. Fastboot doesn't have any command for rebooting into recovery apart from the method I mentioned (fastboot boot recovery.img). Booting into AndroidOS reflashes the recovery console with the stock console (I tried to race it running adb reboot recovery, but lost).
I tore my hair out for hours. Nothing I tried would let me boot into a custom recovery. I eventually backed everything up as best as I could using adb (Since luckily Android OS still worked), and reflashed to stock everything. PROBLEM IS STILL HERE! Then I decide to revert the bootloader from 3.41 to 3.34. SUCCESS. 3.34 booted to recovery without any problems at all.
Any idea what the heck is going on here? Anybody else seen this? All the threads I've seen with people having problems booting into recovery end with somebody suggesting "Just get app xyz that will reboot into recovery" - but that is NOT an option if A). you cannot get it to boot or B). you are not rooted/are running stock, because you can't be in AndroidOS and still have the custom recovery flashed UNTIL you are able to get into recovery to actually fix it.
Here's a video of me trying to flash recovery, since nobody will believe me that it doesn't work. Turn off the audio, the bell noise is obnoxious, sorry.

I brought up the same concerns when I did a manual flash to 4.1.2 and went through a mess eventually reverting to 4.1.1, using OTA rootkeeper than updating again because on bootloader 3.41 *NO* custom recoveries successfully boot.
how do you flash the old bootloader? if you don't mind me asking.
I have been on boot loader 3.41 for a few days and no issues with twrp. I have flashed a few things since and all is good? Sorry not sure why its not working for some.

Huh? I have 3.41 and can go from bootloader to recovery with no problems. Even got a video of it if you don't believe me

You are not alone in this issue, me too, and others more, http://forum.xda-developers.com/showthread.php?t=1932063
I update to 4.1.2 using CWM, didn't lose root. Then changed back to TWRP 2.2.2.0 with bootloader 3.41, now I just updated to TWRP 2.2.3. Everything went smooth even though I'm android noobie.

Code:
fastboot flash bootloader bootloader-3.34-grouper.img
(or whatever the actual filename is). Then you do:
Code:
fastboot reboot-bootloader
You should at that point see the correct version listed in fastboot

I think the issue comes from going back to stock recovery without a rooted AndroidOS. Either one by itself seems to be fine. If you still have the CWR or TWRP recovery already flashed, 3.41 can boot to that. If you have root in AndroidOS, you can always re-flash recovery from ROM Manager or something, and that will work fine. And you can boot to recovery from Android OS (so long as you have root).
If you have stock recovery and no root, your only option is fastboot. And that fastboot flash and boot commands do not work. They look like they work - but they don't. So if you already HAVE a custom recovery, it probably won't even break it.
If you really want to do a proper test / prove this, go back to stock recovery with 3.41. Turn the tablet off completely. Boot up holding the three buttons and go into recovery to see that it can go into the stock recovery console. Then reboot with the three buttons again (don't boot AndroidOS), and run the fastboot boot command to run a custom recovery. If that works, I'll eat my hat.
(well, really all that means is that the problem isn't occurring on all systems. Doesn't mean it's not happening to me and many others)
The problem might not be that 3.41 can't boot to recovery -it might just be that 3.41 can't FLASH or BOOT a recovery console through fastboot. Many people will never notice that because:
A). They already have a recovery console flashed, so it still works
B). They flash their recovery from ROM Manager, GooManager, or whatever
If you lose root, you no longer have B as an option. If you also lose your recovery console, you can't get root access back without fastboot, so you have to use fastboot.

Not sure you've got it right. At least on my N7. My first try was flashing the update.zip in another thread without updating my ROM at all. Running Paranoid Android (2.1799 then) and TWRP. Not sure when in the mix I updated TWRP though.
Thought it might have been a problem with the update.zip, so downloaded the full update.zip from google and tried installing bootloader*.img from that via fastboot.
No change. Reverted to 3.34 without any playing around with deleting files and all is good.

Found the solution to the the issue (sorta), I too went through all this trouble as you did in your OP.
I did not have to do anything other then straight up flash this version "recovery-clockwork-touch-6.0.1.5.b8147-grouper.img" via fastboot and bam! recovery works. Link - http://forum.xda-developers.com/showpost.php?p=32810167&postcount=228
Problem is with previous versions of 6.0.1.0 (Official) and TWRP 2.3.1
I still prefer TWRP, but hey This is better then the alternative (No recovery at all)
Now we need to figure out what changed between CWM 6.0.1.0 and 6.0.1.5 and get the other guys (TWRP) to fix their **** for us poor saps that seem to be a minority in the Nexus 7 world having this issue.
I would love to know what actually the fix is and why only some have these issues with older versions of CWM and TWRP.
Hi,
I'm having a bit of trouble. I had a brand new Redmi 4X, and I was advised to install TWRP, root it, and install the Xiaomi.eu rom until LineageOS is released. I unlocked the bootloader, flashed TWRP, managed to get into it once and now I can't do it again. When TWRP loaded it asked me for a password for decryption but it let me just skip it it seems (not sure if that is the problem) but now I can't boot normally, I can't boot into recovery, but fastboot seems to work okay. How do I go about fixing this?
I've tried reflashing TWRP but I still can't get to it, and I don't really know enough about this stuff to know where I've gone wrong.
UPDATE - I think this is to do with dm-verity and having the stock kernel installed. Now it's too late to undo what I've already done, so I hope to god that someone knows how to fix this.
UPDATE - Right, the problem is solved I think. I had to do an awful lot of googling, and I'm not entirely sure what it was specifically that fixed it. But I found a guide that taught me the fastboot command "fastboot boot twrp.img" which saved the day. Even when my phone wouldn't let me into recovery, it allowed me to flash a no-verity.zip which i think is what allowed me to boot, and it allowed me to flash superSU.zip and then the ROM I was aiming for. And now I've booted into the ROM successfully and hopefully I am rooted and all is well. Plus I can access TWRP as normal now.
Any help would be greatly appreciated
Can you boot into TWRP by pressing the buttons so that you boot directly to TWRP??
Have you tried Command Prompt to boot with commands in to recovery??
And if you get into TWRP you should have everything on the SDCard and then just
format all things except SDCard and then flash from SDCard everything
That is what I would try..and yes it ask for a password but just skip it to get to it
If you can get into TWRP to flash from SDCard then you good to go..if not
Google all the commands for CMD..and plug your phone to the PC and flash everything with the
commands.....
Let us know what is working and what not and what steps exectly you are doing
EDIT
Turn off your device > Press and hold “Power” and “Volume +” buttons at the same time.
After short vibration signal release the power button and wait for TWRP to start.
To boot in stock recovery open “Update” app.
In the setting select “Boot in recovery”.

Thanks for the reply. I can't get into TWRP. Even if I could get into TWRP how would I get files on the phone to flash them?
Is it possible to flash any rom from the pc directly and if it is will this possibly help? I think it's not booting because the kernel is still stock.
I'm not sure what you mean in the edit, how do I boot into stock recovery without being able to boot the phone (and when I have already flashed TWRP)?

Hii
I just have been reading about this bootloop
Go over here and read all of the 6 pages..will not take much time but could help you out much
https://forum.xda-developers.com/xiaomi-redmi-4x/development/official-twrp-3-2-1-0-xiaomi-redmi-4x-t3718217
Hey, I have exactly the same problem. Latest stock rom, flashed twrp in fastboot and got into the boot loop. Nothing works. I can only enter fastboot. What exactly did you do then? What is this no-verity.zip? I can't find anything about it.
I had a problem
I unlocked bootloader then installed redwolf recovery and took a nandroid backup. After that i rebooted to system but stuck into bootloop, could not boot to recovery, could not boot into system, So the only thing worked was that i flashed fastboot rom with mi flasher. And syccessfully rebooted to system with bootloader locked and stock recovery. So, if anyone have same problem you can do the same. How do i install recovery safely again? Should i use TWRP only? Should i flash v3.1.0 with lazy flasher or v3.2 directly without lazy flasher? I don't want to stuck into bootloader again, have to get all data deleted.
I downloaded and installed the official Pie update today, then procedeed to unlock the bootloader which was a success. However now I found that the phone wont boot (not flash) a custom recovery (latest TWRP).
I'm only interested into booting a custom recovery so I can root, otherwise I'd prefer the phone to remain as close to stock as possible.
When trying to boot into TWRP using "fastboot boot twrp.img", I get a success message, phone reboots and then gets stuck at the Android Logo (fastboot commands still work, it doesnt say 'download mode' tho).
Any solutions?
Hey there, I need help. I tried to flash latest twrp for Mi A2 but after flashing everything seems fine on command window but phone isn't booting in recovery mode. Either it get normal boot or get switched off completely , even if I try to boot into recovery by using volume up and power button , it shows 'no command' . I tried to flash magisk and it worked, but after every boot it root is getting lost automatically.. please help.. thanks

Yes it's not easy to flash twrp on mi a2 , don't know why. What you do is go to this link (https://twrp.me/xiaomi/xiaomimia2.html) and download both .img and .zip file from there. Then get into fastboot mode and do the command -
fastboot boot twrp.img
Then it will boot into TWRP. And then flash TWRP.zip file and it will flash it permanently to your device. This step is mandatory so the stock recovery doesn't come back.
Hope this works !! Let me know if it helps !!
I've had my phone rooted until 2 days ago with MIUI10, then MIUI11, also tried all Custom ROMS everything fine until I installed the Global Stable 11.0.5 and as usally it wipes the custom recovery. I ran in this many times, and sorted also that many times by fastboot flash of the recovery. Something happened and right now I am stuck with global stable and cannot install again the custom recovery, tried I think 10 versions.
I open the commander run fastboot flash recovery ...img / fastboot boot ...img and it seems that it all went good, I wait as usuat that it boots in twrp, but instead it is taking longer and every time I end up in a normal restart and boots the system.
I am blocked and don't know what to try to get back my custom recovery, any advices are appreciated!

Try this recovery: http://files.mi-room.ru/files/twrp/cepheus/3.3.1-1030/recovery.img , someone said it's the only recovery which works on his device.
Have you tried to boot into TWRP with power+vol up?
