Need Help. ADB, Recovery and Fastboot/Download Mode don't work

Hey xda community,
last night i run into a tricky situation.
First, I explain what I did
I bought me the P9 EVA-L09 via Telekom Germany.
cause i don't want the Telekom **** on my device i decide to TWRP, Root, and flash P9 stock Rom on it.
Unlocking and install TWRP with the SRK Tool works fine. Install the Root was a bit more tricky, because windows lost the correct ADB connection when i go into TWRP Sideload Mode. Because that does not work, i decide to flash the P9 Stock ROM without Root to come forward.
While flashing, (i don''t now anymore which method i choose to flash) an error appers, and the flash process canceled.
The Device don't boot anymore. After a loot of googeling and testing, i've found out that the problem was the encryption of the /Data Partition.
TWRP was unable to mount it, same for the /cust and one more.
After reading about other Methods to get the Phone work again i try this Method i've found on xda.
http://forum.xda-developers.com/p9/development/stock-rom-dload-file-p9-eva-l09-b136-t3382818
Unfortunately the "press all buttons on the phone" Method don't work.
I also tried out the Huawei Update Extractor to flash single image files to the partitons of the phone. I used the dload file form the previous Method

Download from xda huawei update extractor and extract img files from the update.
Turn off the phone, then press vol- and power key, you are in fastboot mode.
Then, flash img files from extracted rom with:
Fastboot flash system SYSTEM.IMG
fastboot flash boot BOOT.IMG
And do the same with the others...
When you finish, fastboot reboot
Click to expand...
Click to collapse
But that don't work. fastboot already replies with "Remote Command not allowed"
i changed the Method a bit. I've put the BOOT.IMG and RECOVERY.IMG an an SD card and flash it via the Install IMG Funktion of TWRP.
That workes very well and expect the /data partition every partition was mountable again.
Then i used the "Fastboot flash system SYSTEM.IMG" again, and tada it works without errors.
The device is booting again to Android, but it reports that the /Data Partition Decryption failed and i have to enter the Recovery Mode and do a factory reset to unlock the partition. If i reboot for get rid of this error the phone does not boot into the Recovery, it boot to the eRecovery which is useless for that because it only provide the eRecovery function instead of also a normal factory reset (how dump is this )
Now the state is, phone boots normal, reports the /Data is not decryptable, reboot to eRecovery, shutdown or reboot. It does really nothing else.
I can't get into the Fastboot/Download Mode, it ignores the Key Combination Volume down + Power. If i press this it starts normal.
I also can't get into the recovery / TWRP Mode, it ignores the Key Combination Volume Up + Power. If i press this is starts normal.
I've also noticed that the Phone is not conecting to the ADB on my computer, only the virtual CDROM from wich the HiSuite is installable connects.
I've also noticed that the eRecovery is not able to starts WIFI on the phone. It errors with "Starting WIFI failed!"
I also tryed out another time the dload function. This changed nothing. Phone boots still normal and run into the Decryption problem.
And i tried out to boot into fastboot or recovery after a cold reset, battery empty
Now it's on you. Has anybody an idea how i can solve one of the above problems. I think when one is solved the others will disappear via flashing new TWRP or so

Try connecting your phone to usb and then holding power+volume down until it boots to fastboot mode.
Huawei phone won't boot into recovery if system and twrp don't match but it should boot to fastboot allways.
What is the last rom you had on your phone while it was working?

Sent from my HUAWEI VIE-L29 using XDA Labs

I see two possibilites for this behavior:
1) The phone only pretents to reboot but makes a kind of warm start (never running the code to branch to recovery/boot) -> if the phone seems powered off and you attach usb cable, do you see standard battery laoding animation (that's what it should be) or black screen / boot logo?
2) You flashed a wrong boot.img and/or recovery.img or flashing got screwed up
If you have wrong images, fastboot should still work as edint3000 said.
For the unlikely case (1) with non removable battery you have to wait until battery is drained before you can boot into fastboot after connecting USB cable. Edit: oops just saw you did that.
I had another phone that at some point decided to go only in fastboot with volume down and no power button, when powered up with USB power. But I had never such an issue with a Huawei phone. However, playing around a bit costs nothing (but time).
I see no reason why fast boot should not work. How did you find out, that everything is fine after flahing with TWRP and before flashing system with fastboot?
Did you do anything else than flashing the system.img with fastboot?

Same problem here...Phone not boot/not enter fastboot mode/not enter recovery mode...just stuck "your device booting now" screen...any solution?

Hello Mossyhand
you should search for the recovery Method with an "dload" ROM. This are kind of special Roms wich are able to "selfflash" onto the phone.
You have to put the right file onto your SD Card and then you have to press some keys when i remember right.
Sadly i've forgot, when i solved my problem, to reply how i did that exactly ._.
But if you do search in the dload method you will figure a way out i guess
If you don't find an right file, i can upload you my file, i have it still on my computer

had the same problem
go into the erecovery, it will tell you the data partition has been damaged. u can wipe it from there. go into trwp again, install rom and stuff. voila, works
cheers

Flashed Wrong OS; 4x Won't Power On

1. I have successfully requested and unlocked my 4x.
2. I wanted to install: https://forum.xda-developers.com/xiaomi-redmi-4x/development/rom-2017-08-07lineage-14-1-t3653016
3. First step, install TWRP following this: https://twrp.me/xiaomi/xiaomiredmi4x.html (Fastboot Install Method (No Root Required)
3a. Using version: twrp-3.2.1-0-santoni.img as downloaded from the twrp site
3b. After many reboots and tries, finally get into TWRP. Password not accepted at first, press cancel, get to TWRP menu.
3c. Wipe->Advanced Wipe->System,Cache,Dalvik's/Art cache. Swipe, then get errors. Try again, errors. Press reboot option.
4. 4x OS will not boot. It is stuck in endless cycle of Mi logo, and recovery/TWRP boot (vol+ and power) does not work. Only way to break Mi logo is fastboot (vol- and power).
5. Try to reset phone so I can start entire process (starting at 2) all over again following this: http://en.miui.com/a-234.html
5a. Used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=mido_global&b=X&r=global&n=
5b: Edited the flash_all.bat following this: https://www.youtube.com/watch?v=_osMF9EubhI
5c. Left fastboot mode, device will not power on at all.
And as I type this I realize I put on the "Note 4x" instead of the "4x" version. I should have used this version: http://update.miui.com/updates/v1/fullromdownload.php?d=santoni_global&b=F&r=global&n=
As a potential next step I've identified: http://en.miui.com/thread-693884-1-1.html
I need some expert guidance at this point. Thank you.

Recovery is both volume keys plus power.
Maybe you should reflash firmware as well(v32).

you can try it
download and install last version ADB https://dl.google.com/android/repository/platform-tools-latest-windows.zip
enter to TWRP both volume + power. after choose Advanced - ADB Side load .. run it
run command line on PC after: adb sideload /path/to/rom.zip
wait while rom will be installed... press Reboot to System (if TWRP don't reboot byself)
wait near 5-10 min for first time rom startmust work.

I have gotten to recovery with just vol+. Regardless, the phone will not turn on from either combination.

vol+ and power ... have menu for reboot to Fastboot and Recovery .. choose it for reboot to TWRP and flash phone or in Fastboot and flash with Miflash

you know,, if you install twrp,, the combination key vol up+power cannot work,,, he work if you hold vol up+vol down+power until MI logo then realease.

This sounds a hard brick to me.
Every replies about Fastboot and Recovery are pointless, because he cannot start the phone in Fastboot.

either it's hard bricked or motherboard stopped working after the wrong flash.
i think you should give it try on test point method once as you have mentioned in this thread (do it on your risk) or you may have to visit service center since any button combination isn't working for you.
what is the status of device when connected to PC or on charge ? is it charging ? does led light blinks ?

I used the guide I posted in OP to fit it, though it wasn't easy. Gonna try lineageOS one more time. Thanks to all who tried to help.

I had this same. I saved my phone using this toturial:

Be careful with the screen and sim tray!
My phone was 100% dead (no fastboot or recovery). I have tried everything before and only that works.

cannot access TWRP after successful flashing

Hi guys
today was my waiting time over and so i opend the bootloader and flashed:
Twrp_3.3.0_Cepheusv11
xiaomi.eu_multi_MI9_9.5.23_v10-9
Magisk-v19.2
all with success.
The phone (Global version, 6gb+128gb) boots normal and everything works fine up to the point where i want to boot in TWRP. After starting the phone with power+Vol up i get the mi unlocked screen and then for 1 second a black screen, then its reboot and i'm on the mi unlock screen again. Fastboot and normal system boot works fine, i have root over magisk and everything.
Any ideas how to get into twrp again?
Longer version:
After unlocking the bottloader i followed this guide-how-flashed-twrp-xiaomi-eu-rom but with newer files. For TWRP i used the Twrp_3.3.0_Cepheusv11 version from here. The eu rom came from sourceforge and the magisk version from here.
I flashed twrp over terminal from my pc with "fastboot flash recovery twrp.img" and uploaded the rom and magisk with "adb push rom.zip /tmp/" + "adb push magisk.zip /tmp/" to the ram. After disconnection the usb cable i hold down power+vol up while still in the fastboot mode and the phone reboots into twrp. from there it was strait following the guid eg. wipe menu, format data, confirmed with "yes", wipe menu again, factory reset. Install rom.zip, install magaisk.zip both without any errors. Reboot menu and select "do not install" for the twrp app.
From now on the eu rom started up, i connected to my wlan and connected the phone to my mi account and after that to my google account. The rest was normal installation.
After installing everything i debloated the phone with this list. Instead of pasting the full list i chose just the follwing parts:
Android Stuff: none
Google Stuff: none
Xiaomi Stuff: all
Xiaomi Apps: all
Extra Stuff: none
To be Tested yet (try at your own risk):
com.miui.compass
com.miui.calculator
com.miui.cloudservice.sysbase
com.miui.gallery
com.miui.screenrecorder
com.mi.webkit.core
com.miui.providers.weather
Unfortunately is the android.providers.calendar app in the xiaomi app list and my calender didn't sync to google without it. So i read a bit about the com.android.providers.calendar app and learned that it is a specific app for every version of android and i cannot simply use the version from my other phone.
Okay, i thougt, my system is just about 2 hours old i reflash the eu rom and magisk and be done with it. So said, i wanted to boot into twrp, powerd the phone off, hold down power+vol up and got the miui unlocked screen, after that 1 second of black screen and than the miui unlock screen again with is followed by the normal system boot.
First i thought i missed the right moment for holding the buttons down so i installed apps which allowed me to directly reboot into recovery.
But with ervery app it was the same: miui unlocked screen, after that 1 second of black screen and than the miui unlock screen again with is followed by the normal system boot.
So i reflashed twrp over the terminal "fastboot flash recovery twrp.img" and it was stated a success. But again only: miui unlocked screen, after that 1 second of black screen and than the miui unlock screen again with is followed by the normal system boot.
Next i tried to reboot into recovery from adb but it was the same result.
Next i tried to just boot twrp from terminal with "fastboot boot twrp.img" but again, same result.
Next i tried to install different versions of twrp. From beta8 to beta11 i flashed every version but again, same result.
Now i'm sitting here happy with a new eu rom and fully rooted but unhappy with the knowing i cannot update anymore. Any ideas how to get into twrp again?
Edit: i reinstalled my android.providers.calendar after i read the "How to Re-Install an Uninstalled App" section again ^^

I read somewhere the Chinese recovery should work with latest Xiaomi.eu. TWRP is still in early stages.

Re-flash the recovery in fastboot mode. After flashing don't reboot recovery with a command but reboot recovery by pressing vol+ and power, keep both pressed untill you see twrp booting. Happened with me as well but than got sorted by flashing again after setting up the rom, enabling usb debugging and going back into fastboot and flash. And can I ask why did you use version 11 when the latest on that recovery is v17 beta and a final version but v17 is good and decrypts as well, hope this helps, cheers.
version 17 is on this page: click on the mega link

The system has been destroyed

Hello, after unsuccessful OTA update my phone doesnt boot into Android any more.
I had an original, untouched xiaomi system (not a custom one, not rooted etc).
Bootloader locked like default.
I think update.zip could be faulty - I have no idea how.
I am able to run Fastboot but due locked BL I cannot do much there.
I deasemble phone, pull out the battery, connected EDL pinouts with a wire, and all this togetcher connecter to PC.
Phone is visible by PC.
Downloaded ROM, and tried to flash via MI Flash..
On last moment I am getting error with information that my mi.com account is not athourised to do such a thing.
I tried also Mi Flash Pro founded on Cyanogenmod forum, but without luck - still getting same error.
Does anyone know how to get out from this situation or should I rather open warranty process in Gearbest?

Just flash a custom recovery, the device even had the offical twrp. So?? Just not into fastboot and then flash the recovery by the -- command
fastboot flash recovery recovery.img
(You have to rename the twrp file to recovery or whatever, just write the image file name instead of recovery in the second one. Ex fastboot flash recovery 123.img)
Then command
Fastboot reboot
(Hold the power up button for booting into twrp before hitting enter)
Download a miui recovery rom for your device from anywhere, I don't know I'm lazy.
And before flashing, go into mount select vendor and system if not selected.
And then select wipe
Advanced wipe
Select vendor system data cache.
Swipe to clean
Move the rom to your device
(If your device does not show up in your pc, then go into mount (twrp) select enable MTP if it's disabled, if it shows disabled then enable it again)
After that just flash your rom and then a permissive patch you can ask anyone. Or just flash pitchblack recovery. Fixed my problem of not not booting.
Sorry for the wrong format, wrote it on mobile, as I am a lazy bum.
Wut bruh.

Something similar happened to my friend's Poco F1. It was locked and I only could boot into fastbook, looked everywhere for a solution and found this lifesaving tool . It may work for Redmi 8 too.

Question Phone stuck in boot loop, unable to get to FastBoot

Hi,
Sequence of steps:
1. Extracted the boot.img from payload.bin and flashed it to the phone. At this point I was able to get into Fastboot
2. While in Fastboot I went into advanced and wiped the "System Settings", and that's when the trouble started - now the phone is stuck into a boot loop forever, I do however get the options to "Power Off" and "Restart"
3. But none of the options above in Step 2 is able to bring me back to Fastboot (and hence into fastbootd either)
Question: How can I get the phone into Fastboot Mode - have tried MSM Tool v4 as well, but that doesn't even recognize the phone

Edit - This seems to have been resolved now, think I had to press Vol Down + Power instead of Vol Up + Power
Was able to enter into Fastbootd as well, will try to proceed with unbricking the phone with a fresh mind tomorrow

FYI for others reading I was able to install magisk by booting the patched file (dump the payload using the python script mentioned above). Running the command Fastboot boot filename boots into the operating system and then magisk can be installed using the direct method.
I assume running this command the phone doesn't actually flash the boot image but could be wrong

Thats right, "fastboot boot <file_name>" loads temporarily your custom recovery of choice. After rebooting your phone, the custome recovery is gone.
Otherwise, the command "fastboot flash <file_name> recovery" flashs permamently your custom recovery of choice to your device.

Hi I have a oneplus 8t and I tried flashing a payload.bin file using fastboot enhanced. after the operation completed I tried to reboot but the phone only shows the logo and then the bootloader unlocked warning message and then turns off briefly, then it does it again and the screen goes black. When connected to the PC, the PC recognizes the devices as android adb recovery devices but i can't do anything from there. Tried the volume up+power combo and it just does the same thing. tried the volume down+power combo and absolutely nothing happens. If i could at least get to the bootloader I could unbrick it but I just can't get there. Any advice

I have exactly the same issue, on a nord 2

How about vol+/vol-&power all together? When stuck that gives me some screen that allows start, recovery (the one where you can enter advanced settings I expect from your description) and bootloader booting.
