Hold down the power button and vol down button untill the phone reboots to the bootloader again. Make sure its in fastboot mode and type
Code:
fastboot erase cache
Then type
Code:
fastboot flash recovery recovery.img
Then
Code:
fastboot reboot-recovery
Hopefully it will boot into recovery.

only works on hboot 1.44.
as mentioned above hold POWER + VOLDOWN (under a bright light), when it reboots let go of POWER but keep holding VOLDOWN, once in bootloader follow steps above to flash recovery
i think "fastboot reboot-recovery" doesn't work (at least for me), so do a "fastboot reboot-bootloader" then enter recovery.

I had the EXACTLY same error as you. Didn't know what caused it. After about 20 attemps I finally managed to flash it. I changed the USB Port several times... But I didn't do any other things. Just try and try and try again. And whenever your screen freezes, do what @nkk71 said.
Volume down + Power button for several seconds...

OK, I have resolved my problem, thanks all of You.

unable to flash recovery on CRR-UL00

Hi all - I'm not entirely stupid, but I'm probably doing something basically wrong here.
I'm trying to convert my Chinese CRR-UL00 to something a bit more western, but still with dual SIMs, so converting it to Middle East/Africa model seems like a good idea. I'm not interested in root or even a custom recovery in the long term. I just want to change regions.
I have been trying to follow the instructions both here and elsewhere but am getting stuck early in the process. I've tried a bunch of different things so my phone may be in an odd state.
I have, I believe, unlocked the bootloader via DC-Unlocker. When I reboot into the bootloader (using adb reboot bootloader) I get a white screen with a header that says "Fastboot&Rescue mode", an Android icon, and "Phone Unlocked" in red underneath.
Attempting to flash a TWRP recovery.img using fastboot doesn't seem to have any effect, even though fastboot reports it has successfully transferred the image. Trying to boot into recovery - either using adb/fastboot or vol+/power keys results in the phone hanging at the Huawei logo at bootup. I've also tried to flash back a "stock" recovery.img. At no time have I been able to get the fastboot menu on the phone - it's either the white screen with no options, or the phone hanging at the Huawei logo.
Despite all this the phone will still operate normally! When operating normally the phone now reports its running CRR-UL00C00B172.
Any ideas what I'm doing wrong? What recovery.img should I use?
Thanks for any help!

I'm not home right now but from memory the one I've used was named somthing like TWRP-2.8.7.0-Carrera.img

Thank you for the quick reply. I've had some time to have another go at this. Still can't seem to get TWRP recovery onto the phone...
It seems to flash...
C:\Program Files (x86)\Minimal ADB and Fastboot>fastboot flash recovery twrp3.img
target reported max download size of 471859200 bytes
sending 'recovery' (24454 KB)...
OKAY [ 0.532s]
writing 'recovery'...
OKAY [ 0.242s]
finished. total time: 0.787s
but then rebooting and holding down various keys to get into Recovery, I either get a hang at the Huawei logo, or I eventually end up back at the stock recovery. (I think if it boots to the full OS it overwrites any TWRP recovery)
What is the actual key combo to get into recovery? Various web pages report different combos:
- vol+ and vol- and power
- vol+ and power
- ?? something else
Many thanks,

- flash stock recovery
- boot device normaly
- go into developersettings and look for OEM-Unlock
- if available, enable it. if not go to fastboot mode and use "OEM-Unlock" command with code again. (sometimes the bootloader isn´t unlocked fully on first try)
- then try to flash TWRP 2.8.7.0
- fastboot reboot
anyway whats your current build?
i can only access recovery via. "adb reboot recovery" command

Thanks for the help. Clearly I'm doing something wrong.
On rebooting normally after flashing recovery I don't see an OEM-unlock option in Developer Options. Attempting to fastboot oem unlock again gives me failed, already unlocked.
I've tried four different downloads of TWRP recovery from different places, I've even tried different adb/fastboot binaries to make sure that's not the issue. The TWRP recovery images I have are:
25,040,896 bytes (three different downloads, and I've seen one or two sites that claim this is only for the L09 version)
25,378,816 bytes (from a random Chinese web site that says its for the CRR-UL00 B131)
I'm on CRR-UL00C00B172. I wonder if I need to flash everything back to something earlier? (e.g. I have a full download of UL00C00B153).
wd

OK, success!
At some point I ended up in stock recovery and it suggested to download and install UL00C00B131. (why B131? Maybe because at some point I had been using the Chinese download with B131 on it?). Did so.
adb reboot bootloader
relock and unlock to confirm unlock is definitely working in fastboot
fastboot reboot
adb reboot bootloader
fastboot flash recovery twrp.img
fastboot reboot
adb reboot recovery
...now I'm into TWRP!
Thanks all for your help.
wd

...and now I've got it localised to MEAFNAF (C433) - so still dual SIM but with Google Play by default etc. Running CRR00-UL00C433B146 which is available from Huawei.
I followed these instructions. (based on the original Russian post but much better than Google Translate
At the end, the install of update.app hung at 90%. Using vol+/power to get into recovery dropped me into a Chinese recovery (probably from the recovery.img I flashed back to remove TWRP). Factory resetting from recovery resulted in booting to the full OS, but I didn't get the option to enter a Google ID in setup and the full OS was dog slow with a black home screen.
Doing another factory reset, I was then asked for a Google ID during setup, and this time resulted in a fully functioning Googley OS.
I understand I won't get OTA updates as I've changed my localization, so I'll keep an eye out for the final Marshmallow release from Huawei's web site.
I hope this thread is useful to others.

can only get into fastboot after trying to flash twrp recovery

I was trying to follow the steps in this guide - https://forum.xda-developers.com/oneplus-3t/development/recovery-twrp-oneplus-3t-t3507308 - and I got hung up at step #7. After flashing the twrp recovery in fastboot, I could not get it to boot into twrp recovery.
Code:
fastboot boot twrp.img
That returned with
Code:
[email protected]:~/$ sudo fastboot boot recovery.img
downloading 'boot.img'...
OKAY [ 0.069s]
booting...
FAILED (remote: bootimage: incomplete or not signed)
finished. total time: 0.089s
And when I tried to reboot it took me into what I thought was the stock recovery warning me that my device was unlocked and not to be trusted and gave me the options to power off, restart, recovery or fastboot. Fastboot takes me to the fastboot mode. Recovery takes me back to this same screen warning me that it isn't to be trusted. Powering off and restarting either take me back to the warning screen or simply give me a blank screen and the white led on.
I don't know where to go from here. I've downloaded the stock rom but I don't think I can flash that from fastboot and I can't get connect to the phone with adb because I can't boot the phone.
Does anyone have any suggestions? Aside from to stop messing with stuff when I don't fully understand what I'm doing that is...
Thanks for any help!
Jono

Go back to fastboot and try booting the stock recovery. Then choose to update worry ADB sideload. That worked for me, but I'm still having issues with TWRP.

Thanks for the reply! When I try that it just takes me back to the screen that says it can't be trusted because it's unlocked and 5 seconds later if I haven't pushed the volume keys it shows the oneplus logo for a second and then the screen goes blank and the white LED comes on.

solved
Ok, I managed to flash the stock recovery; which I downloaded from oneplus directly. I'm a new user here so it won't let me post a link but they do provide a download for the stock recovery there.
At that point I was able to reboot into recovery, and now I can get it to start up again. Here's what I did in case anyone needs help.
Code:
[email protected]:~/$ sudo fastboot devices
[sudo] password for jono:

Hope that helps anyone else. After I did that it rebooted and took me through the whole setup procedure. I'm going to hold off on trying to root this thing for now.

Recovery bootloop

Guys, here's the problem:
I've clicked reboot to recovery in power menu in Pure Nexus ROM and now I'm stuck in recovery bootloop.
The phone tries to boot into recovery, shows the leeco recovery message and then flashes red triangle android robot and just shows black screen. If I connect to PC at that point, adb recognises a device in recovery mode. But I can't flash anything.
If I try long enough I can boot into fastboot, but then I get the "Android Bootloader Interface" in the device manager - but adb doesn't see the device.
Any suggestions? Can i somehow make ADB see the device so I can reflash TWRP?

Dear
Press and hold vol - and power button together, then your phone will boot into fastboot mode.
then simply you can use fastboot commond below to flash recovery.
fastboot flash recovery recovery.img

OK I've managed to get my PC to recognize the device. Now fastboot sees the phone.
The thing is that I can't flash anything. I had probably disabled "Allow Oem Unlock" in Developer options.
So I have fastboot but can't flash anything there. Any suggestions? If I reboot without holding Vol- the phone tries to boot into recovery and fails.
EDIT: At this point I can either boot into fastboot, where I can't do: "fastboot oem unlock-go"
Or boot into recovery, which doesn't load properly, all that's left is a blank screen - but ADB sees a device in recovery mode"
Is there anything I can do to get out of those two options?

I want to know which recovery you tried to flash through fastboot. It may not allow you flashing twrp ultill oem is locked. You can try flashing stocking recovery.

Tried that, it tells me that I can't do this because the phone os locked. Now I'm looking for Stock recovery IMG for x522

Its the same whether its TWRP image or stock recovery image.
I was thinking of using this:

But, unfortunately, there is no file for American x522.
It sucks to be able to get into fastboot and not be able to do anything.
Thanks for the suggestions so far

Try Leeco AIO tool kit to reboot your device into recovery . It's working for me

leco le 2 x520 recovery problem
I have a problem with recovery in le 2 x520. It installs via fastboot by unlocking the bootloader but stops at the Le recovery logo and nothing else happens. I installed from version 3.0.2.0 to 3.1.1.1 and nothing happens, I do not have recovery and writes everything okey went. what is going on ??

I have same problem. how to fix

I have a new one (acutally two, got them for U$D 108.99 each one)
Using ADB devices it recognize the UID like 0123456789ABCDEF, so I think the recovery is corrupted, intentional or not, it is blocking fastboot and recovery to load normally.
At this point I can't do anything.... any suggestions?

You solved it ?
I having the same issue maybe the issue is with stock rom since i flashed in normal twrp,chinese twrp and also that stock recovery.

p8 lite bircked - rescue mode func no 7 - how to boot into twrp via fastboot

hi have a bricked p8 lite in front of me. when i start the phone im in rescue mode and get the rror:
func no 7(teeos image)
error no 1(security verify failed)
with power button + vol+ i cant boot into recovery. phone does nothing. just blinks red.
booting into fastboot is possible. bootloader is apperently locked(phone locked). if its possible to install twrp with a locked bootloader then ive done so via this tutorial. if not, am i f+++ed because huawai doesnt give out unlock codes?
i guess it doesnt work with a locked bootloader:

is it possible to reboot into recovery via fastboot? fastboot reboot recovery dosnt seem to work.
any suggestions what i could try next?

with locked bootloader, you're pretty fu****d... but, some third party app/sites give bootloader codes for some money... had something similar long time ago, fortunately for me, I had my bootloader unlocked... I guess there aren't other solutions... and from fastboot, you can't go to recovery...

okay found this, you can try it... I too got my code this way, but back then Huawei was open to unlocking bootloaders, now cannot say... but you can still try

unfortunatly the led just blinks red when i press all 3 buttons. flashing a stockrom or parts of via fastbootin locked bootloader also isnt possible i guess?

today i unlocked ale-l21 with dc-unlocker for 4 euros.

You need to install stock android 5 and root it with kingroot, then open a bash terminal and get the bootloader code with grep, there's a tutorial on how to do all of this, and it's free. This should also unbrick your phone. If you have an sd card you should be fine. If not, you may encounter complications but you should be able to do it too.
