[Q] P7 fastboot limitations - Huawei Ascend P7

I've been playing with custom boot images for the P7 (I run Ubuntu in a VM on my machine). Unpacking, repacking is not a problem. But I've discovered that "fastboot boot myboot.img" doesn't work! The error message is "remote: command not allowed". I know I can flash my custom boot image that is "fastboot flash boot myboot.img" certainly works. I've only done this once as my phone fell over and I had to rebuild it. Time consuming as you know. Is this a special feature of Huawei phones designed to make life interesting? Is there a work around/solution?
Edit:
I've found much to my dismay that Huaweis implementation of the bootloader is highly constrained. Most of the normally available fastboot commands have been turned off. Very disapointing. No easy way to test if a custom boot image works without flashing. And then if it doesn't, one has to rebuild from scratch or re-install from a nand backup.

[Q] booting from fastboot problem

so I've been playing with the options long enough that I'm not satisfied with what's available, so I figured I'd try customizing a kernel myself. I think I have a pretty good idea about how to make that happen, but I've run into a problem on testing. I can't seem to boot using fastboot boot ______. Whether I'm using the twrp recovery boot, dd of mmcblk0p35, or the freshly split boot.img(ramdisk and kernel), fastboot responds with ok, but my phone sticks on the bootloader fastboot usb screen, requiring a hard reboot. Is the only option to use the any kernel zip? or am I just screwing something up?

The strangest problem with oneplus i have seen!

Hey!
So i'm making this post after battling over 4 days with my friends old oneplus 3t.
All started maybe year ago when my friend asked me for help because his oneplus had suddenly gone into a bootloop kind of state (he told me that the phone was in his pocket working fine and when he tried to use it next time it started acting up.) Before i could even help him he had already bought new iphone, so the oneplus stayed in his drawer until last week when i remembered it and started to try to fix it.
So first thing that i noticed was this message "The dm-verity is not started in enforcing mode and may not work properly", the message eventually went away and i got to a recovery mode and thought that this is gonna be easy, hooked the phone to pc and started adb and tried to sideload the official rom from oneplus site, but everytime i tried it went to maybe 47 %or 66% and failed eventually. So i thought that ill try flashing original recovery.img, started fastboot and tried flashing and everytime "remote: Partition flashing is not allowed". Tried many times also oem unlock command and failed miserably, all i got was "remote: oem unlock is not allowed". Eventually trying every command from fastboot and adb i came to a conclusion that the device doesn't allow anything to be written to its storage (Tried of course flashing twrp, but same error).
Downloaded Oneplus 3T unbrick tool v3.0, and qualcomm drivers (turned windows driver signature off) everything went great and the green text came in oneplus unbrick tool and i proceeded to start the phone in excitement and the circling bootlogo started and it just stayed there, nothing, and after while shut down.
Things tried now:
-Sideloading (many times with different roms) no success.
-Fastboot (It recognizes the device everytime, but all other commands than "fastboot devices" end to an error"remote: something not allowed") no success
- Unbricktool v3.0 (Works like a charm everytime, but phone doesent still boot to os) no success
-recovery (wiped cache and all data many times) no success
My friend never flashed anything to this device, he doesn't even now how to do this kind of stuff.
Phone not dropped even once, is in a perfect condition and has all the original stickers even.
I have grown obsessed to fixing this phone, so any help is greatly appreciated :laugh:

I haven't personally ever had to use the unbrick tool, so I can't help too much with the core problem. But what I can say, is that the steps I've quoted above (trying to flash recovery partition, etc.) are going to fail by design, since the bootloader is locked. This is the very purpose of the locked bootloader. The expected result is "remote: not allowed".
And as far as I am aware, you have to have a working OS and have "OEM unlocking" first toggled on, in the phone Developer settings. Otherwise (again, by design) the "fastboot oem unlock" command is going to fail.
Spontaneous failure of the phone to boot to OS, and dm-verity warning, to me probably indicates the OS has become corrupt/damaged. The damage is showing as a change to the system, therefore the dm-verity warning. Normally, I would tell you to flash the stock recovery image. But of course you have already tried that. Probably difficult to determine for sure. but spontaneous failure, and failure to flash recovery image (multiple times) may indicate a hardware failure such as bad emmc.

Lancelot enters fastbootd mode, does not communicate with adb and it's command, can't install twrp

Hello there.
Just like title says - I've got my hands on new Redmi 9 (lancelot) nfc 4/64 version. I've unlocked it from Mi stuff successfully yesterday and wanted to install there twrp, magisk and titanium backup to clean a bit and maybe to have foundations for further change of rom.
However, my phone gaves answers, that I do not understand correctly.
Firstly - after first instalation of twrp via adb it booted into this. However, after choosing option to boot to system from it, power off via ui and then another try to enter recovery...it gave me stock miui recovery again. When I've tried the same steps for second time, phone finished, but after restart it entered bootloop. I've followed steps from this guide - https://miui.blog/redmi-9/download-install-twrp-and-root-redmi-9-codename-lancelot/
After some time I've managed to make low-level rom instalation again (12.0.4 official lancelot rom, dated 31st of Mar, 21) to at least being able to communicate with it (done with usage of miflash 2018 version and rom in *.tgz file). This time, I've used help from this page - https://www.getdroidtips.com/guide-flash-miui-rom-xiaomi-devices/ - had some troubles with mediatek based phones before in my life, so it wasn't from scratch, but some time to understand it were needed.
Phone is working again, but this rom is based on Android 10 (which I would like to keep, if it won't cause too much trouble). And I think because of that fastboot mode changed now into fastbootD mode, where old commands from adb does not recognize the device, thus no flashing recovery action etc can be taken.
Is there a workaround here? I've stumbled across some articles about installing clean Generic System Image with Android 10 on this phone (since it has been released with android greater, than number 8), but again - this requires to have custom recovery, prefeably twrp. I cannot do anything about it, because I got back to stock recovery (which now at least works, yesterday phone was so twisted at one point, that he cannot even load this recovery, but somehow managed to open system and fastboot modes normally (!!!)).
Is there a way to work it out? Older miui version, older android version, then twrp, then update via twrp? Or an alternative method, since google changed something in partitions again (not sure, if I get it right, but it might be it)? I would actually like to stay somewhere around miui (at least let it be official with ota support without too much issues), but without twrp I cannot do anything. I also do know, that there aren't any official twrp/pbrp yet (just betas). Could it also be the issue with troubles with installing it and staying it on the phone?

After to flash TWRP you have to flash the vbmeta.img and then boot to TWRP not through commands but manually with hardware buttons, don't allow device to boot to system before to boot to custom recovery otherwise this will be overwritten again.
I've done that with this vbmeta, one and only difference might be that I was trying to get into twrp by commands (however, it did not work XD). Overwritten isn't an issue in my opinion, since I do have booted to recovery after installing it yesterday and then from it choose option "reboot to system". After poweroff from system and then trying to get into recovery, then stock showed.
I'm currently trying this - https://c.mi.com/oc/thread-3312019-1-0.html
After putting this command to cmd - bcdedit /set testsigning on lancelot shows somewhere, but I cannot install it (most likely due to this issue about encrypted drivers). I'll try to overcome it now.
Yea, well, I've tried this method from link listed above, phone still enters fastbootd mode, still is not-visible from cmd started from google platform tools folder (which a subfolder to working adb). Not sure what to do now.

No, this is not the method to boot to recovery from what I pointed out, you don't have to firstly power off device but from fastboot commands you can type either fastboot or fastbootd reboot and inmediately press the volume up till the TWRP logo appears, the fastboot/d command will act same as it be the power button.
The thread explains how to install unsigned drivers in Windows, not to set it on your Redmi but is for your PC. If you succesfully get the drivers installed then you have to reboot your PC entering again in safe mode (not normal mode) and from there the commands through fastbootd are generally the same than those for fastboot.

Just to be sure you are doing fine and not missing something the adb commands work while device is on and fastboot/d commands work only in fastboot mode.
Can you attach some SS to see what you are typing and the error that brings the cmd?
Hm, you say, that I can type fastbootd into cmd and this will be recognised? It seems that it cannot be recognised in this case, when I'm trying to type fastbootd powershell says "unknown command".
Typing fastboot /d devices results in "waiting for device", despite phone being in fastbootd all the time.
I'll attach ss tomorrow - it is time to sleep for me now, gotta wake up early. Then we will also know something else, when it comes to behavior after restart pc (once again, I've done it all in one sit, it might be an issue here).
PS. if you want english errors, I'll have to use powershell - cmd is in my native language (polish). Found out, that it doesn't really matter, which program you use, powershell simply can do more, while cmd dates back 30 years or so.
Anyway - phone is still booting to miui 12 and android 10 normally, I do not set there google acc or lock yet, so don't know if there's any issue with it (most likely no).
I've also stumbled across some dude from indonesia, who had the same phone, miui 12.0.1 with android 10 and he installed successfully twrp, then magisk, but he also put some small img - misc misc.img. Could it be the issue?
I'm giving link to this material on YT -
FROM WHAT I SEE IN THE THUMBNAIL, this version of twrp is even the same (code number and english translated from chinese), that once worked here (md5 of the file might be different, though).
There's also an option to reinstall again whole adb, platform tools, drivers from official miunlock app etc, but since I do not had ANY android-related problems on this pc with previous phones, I'm not sure if this is worth our time.
And I think that if I would misspell something in cmd program would give me error instantly, instead of behaving like it was nothing - i've made tons of errors before and cmd/powershell always informed me about it in first line of their texts.

Yes, fastboot works normally while in cmd, this is intended for that, no problem to enter firstly toi Power Shell but you can switch to cmd from PS just typing cmd and all the commands from here will be for cmd, doesn´t matter at all how many old is, cmd can work inside PS keeping the same aspect.

You don't need to reinstall nothing, just from the downloaded SDK platform do all that you want to avoid misspelling path and folder directories, I mean place the files you need to use in the same directory and open terminal prompt (PS) in the same folder where adb/fastboot binaries are, pressing right mouse button and shift at same time.
I feel you are missing something simply here, not so hard to do.
The misc.img partition that you mentioned is just to restore something that went wrong in the process.
But if you are happy with this Miui ROM then great. No hurry to answer that, give your time to rest.
I also feel, that there is something simply to overcome, Only the fastbootd is new Stuff to me. However, any time I was doing something with Snap, i was long after finish by the current time (almost a month with It and 3rd day with fastbootd issue).
I don't get it. Now when I've tried to enter fastboot mode...phone entered it (fastboot, not fastbootD). Then I've installed pitch black recovery and sucessfully booted into it by restarting phone and then pressing vol up. Now I'm trying with magisk and another entry to pbrp.
Second try gave me stock recovery again. What is wrong with it XD?
something is wrong. Installing twrp resulting in nothing (stock recovery is still there), installing pitch black resulting in successfully boot into new recovery. However, this recovery does not see any zip (magisk zip, to be exact, that I've put there before it to root phone). After boot into system and then power it off to boot into recovery...phone boots into stock recovery. Should I downgrade system to miui 11 to be able to get over it? Or should I wait until miui 12.5 enters redmi 9?
My tries of installing it has been done by using cmd with admin rights, if it does make any difference.

I think you are not following the right direction, if you want consider what I pointed out; you don't have to power off device prior to boot to recovery for first time but you have to type from fastboot (no matter fastbootd) and inmediately from there boot to the custom recovery, when you succesfully booted to custom recovery then flash the recovery zip if there is one (PBR and OFR have one) and if not a zip then flash the image again to the recovery partition, also check if there is some installer apart from the image that can fix it in the ramdisk partition, at this point your issue is solved, next step is to reboot device to system normally, if you don't have any issue on that then OK but if you can´t there some steps more that you should do, but let this for last.
Ok, let's group it.
I do not think that particular matter of how do I restart phone matters here (at least, I do not believe it, that it does anything).
Option to restart to recovery from adb still not working.
Trying to find magisk.zip in main directory of internal storage still fails under pitch black recovery project.
From new stuff - I now got an error message, while opening pbrp, most likely with the issues about system being read-only (not sure though, since I do not remember it now, might look into it once more). I have the options to mount partitions, available from main menu, but since I do not used it at all before, I do not know, how to deal with it.
Also - my system boots normally, it must have overwritten recovery (or at least header of it) sometime during boot, since custom recovery is unavailable to access after first full reboot.
I'll try now to install newer version of twrp from yt that I've posted days back. I would also try with orange fox (however, i cannot find img for it, just source code, don't get it).
Is there someone, who can and will to help me?
Situation looks this - on this 12.0.4 MIUI with android 10 I'm unable to install ANY recovery (either phone do not restart to recovery after proper command from cmd or it boots into it, but after visiting system and then to recovery again it shows stock (even without any operations or updates from ota).
I cannot force to work either twrp 3.4.2b, twrp 3.5.2, pitch black recovery 3.0.0 beta.
After trying to install magisk 21.4 zip from twrp 3.4.2b phone entered bootloop, because f**k you, user, I cannot even get it to fastboot mode now (btw, fastboot now works, fastbootD is luckily a long-gone crap).
All cmd's have been run with admin rights. There are NO SUCH THING, as misspelling (cmd and adb would not execute command ,if it is misspelled, either command or filename). I've installed drivers once again and used cmd from dedicated folder with adb fastboot portable version (runned as admin, of course).
Now I'm downloading older version of rom for fastboot (miui 11.0.9) with android 10. Something has to finally work on this piece of junk.
Writting each time is success (cmd says "OKAY" nad displays time, it took to do so), downloading recovery image to start from it also works, there aren't any errors in cmd, yet phone still isn't working.
Where's the issue with it? Apart from being mediatek, which seems to somehow enormously hardened any flashing? I did not encounter anything like this with qualcomm, yet mediatek still manages to pisses me off with their really weird implementations and working (???) of their stuff.
another update from battlefield. Managed to finally get mediatek verify bypass in smart phone flashing tool, however it ended with forcing me to format anything in the phone (if not, program would not let me install anything).
Second problem is forcing me to disable verify, yet command fastboot --disable-verity --disable-verification flash vbmeta vbmeta.img put in fastboot mode (yes, it works now) does not work, because adb says, that "--disable-verity" is not a recognised command.
SPFT cannot properly download images from phone and welcomes me with error about download exception, happening either in recovery part or in boot part. SInce I do have access to fastboot now, I can overcome it (I think).
Old miflash tool to install roms via fastboot says it cannot flash rom in locked stage (I might have lost unlocked status, but I'm not sure about it). Do you know ways to overcome it?
It is me again (inb4 use edit). Had to unlock phone again by using miphone unlocker (it went ok). Still cannot flash using SPFT, miflash started showing idiotic errors like "no file in directory" or "cannot access to directory" (it could before, I did not changed name of it). Will continue reporting of progress (or the so-called "progress").

Question [Fixed] ASUS logo stucks on recovery, only access to bootloader

Hi all,
I'm encountering a very annoying issue with my brand new Zenfone 8.
I wanted to install the last LineageOS image, but now my phone seems stuck.
Here are what I did:
- Unlocked the bootloader: success with the ASUS APK after a few tries (error 11000 and 11006 ans eventually worked).
- Rebooted to bootloader
- Entered into recovery
- Used fastboot to flash the vendor partition.
At this point, everything looked OK. But then.... :
- Powered off the phone and restarted to bootloader.
- Tried to enter into recovery to flash the Lineage Recovery
But at this point, I had a ASUS logo stucked on the screen.
I can't do anything with adb or fastboot commands.
I tried the method explained here (https://www.asus.com/Content/Android-13-Beta/) to rollback to stock Android 12, but nothing happened too: I looked at the shell script (I'm on Linux) and I reckon that it stucks on fastboot command (the phone is in the bootloader).
Any idea about what failed? The last command used (vendor partition flash) said "OKAY".
And especially, what can I do now? Any way to reinstall the ASUS recovery?
Thanks in advance guys.
Not quite sure what your status is if you say "can't do anything with adb or fastboot commands". I've flashed Zenfones a couple of times (my household has 3 Zenfone 8's on LineageOS) and I had one that went into ramdump. I recovered from that using fastboot to manually reflash all 19 firmware partitions, in both slots. That got the phone out of ramdump, and I got to continue the upgrade to the new LineageOS. So: if you can boot to the fastboot environment, then that would be a road that might leaed you out. But if you can't even get a response to the command "fastboot devices" then I don't know of a course of action for you.
To use fastboot commands I had to run the phone into bootloader mode, then to "recovery" and eventually "fastboot" (I'm note 100% sure but it's what I remembered).
Without that, I was unable to use any fastboot commands like device or flash.
And now the issue is that I'm not able to go to recovery/fastboot again, because I have just the ASUS logo and nothing else.
It looks like that the stock recovery was dead, but I don't know why - and I don't know how to fix/reset it.
From the bootloader you should be able to flash the raw image again, it should flash everything

Good to know - but with which commands/tools?
As I said, I was unable to use fastboot commands from my computer on the Zenfone bootloader.
On the bootloader page, I just have "waiting for devices" and noting else. I had to go into the recovery > fastboot to make the commands work.

On Linux and maybe macs too you need to run fastboot commands as Root (sudo fastboot devices) for example. The raw image script should ask you for your Root password for this reason
Yes I know - I well used sudo for all commands.
The ASUS script asks me for password but then does absolutely nothing - not even a print. I waited a few minutes and finally canceled.
For you, fastboot commands should work on the bootloader screen? (I ask that because the script starts by a fastboot command).

Yes, they work from the bootloader, I always run the script from the BL too. Ironically, I had issues running fastboot commands from fastbootd for installing Omnirom, so I did it all in the bootloader and all worked fine.
I am not sure I can help you more at this point, it looks like it maybe got interrupted mid flashing and now something is wrong somewhere. Maybe if you look inside the bash script file you can find the command that it got stuck on and run that manually if you manage to get fastboot command access.
Strange - they have never worked from the bootloader. I tried that before according to the LineageOS wiki. I thought it was a mistake and use the recovery > fastboot to do that. I dont like that - I hope it's not a local version of the Zenfone or something like that.
I'm not at home tonight but yes I'll try to find commands not requiering the fastboot command.
Unfortunately all commands from the script are using fastboot. And as "fastboot devices" sees nothing, I can't do anything.
I've tried from the bootloader screen (with start, recovery, poweroff option) - from the start screen showing unlocked bootloader warning and from the ASUS logo when I try to start the recovery. I've tried the commands/scripts with Linux and Windows: same result.
So :
- I can't use any fastboot commands.
- I don't have the ASUS recovery.
Speaking of the ASUS recovery, I've found screenshots on internet and they don't have a "fastboot" submenu (I'm not sure it's a Zenfone 8). May had I a different version?
I don't like that. If I don't have others option, I guess that the warranty doesn't work because the phone is unlocked?
I eventually found a solution! I've tried with my old OnePlus cable and fastboot commands start working from the bootloader screen.
I have no idea why my other cable was faulty (it can charge the phone and executes commands from the Recovery > Fastboot menu - but not on the BL screen).
Anyway my problem is now fixed.
Thanks all for help and support.

Question Un-softbricking a PEEM00

We have a few Chinese Find X3 Pros for development and were looking into rooting them for more advanced development capabilities (especially around the Hexagon SDK). I went through the "deeptest" application process, got my bootloader unlocked, and applied some sketchy Magisk boot image I found. Unfortunately, I think the boot image was for the international version (the CPH2173), and it was unhappy with that. It rebooted back into fastboot. Foolishly, I flashed the image again, only for it to go into the *other* boot image slot. Oops.
I notice fastboot says "Secure Boot: Yes", and I'm curious what exactly that means. Is there a way to turn that off, or is that a fuse that's blown? If I can't disable it, how far does the verification process go? Before fastboot? Including fastboot? vbmeta?
I made *some* progress by flashing vbmeta (again, from some CPH2173 firmware) with --disable-verity and --disable-verification. Then, I can send it the boot image via fastboot boot boot.img and make *some* progress. However, after about 10 seconds, it just crashes and goes back to fastboot. Is there a way to get a log of why it failed?
I've heard that you can't use an international version of the firmware on a Chinese model due to partition size differences. However, the CPH2173 files I have also have all of the partition tables that I could theoretically flash. There's also some files I could use with Qualcomm programming tools if I could get it into EDL mode (assuming it would pass the secure boot checks). I'm a little skeptical about going down this route as it might get this device into an even more bricked state.
I do have another Chinese Find X3 Pro that I can *temporarily* get into EDL mode by tapping the version number in the fastbootd/recovery screen. Unfortunately, it quickly leaves EDL mode before I have a chance to explore what's possible. Has anyone been able to pull off existing partitions via EDL mode?
Any advice for recovering this device?
