Fastboot not working - Android Q&A, Help & Troubleshooting

Hi everyone !
Some month ago I flashed on my device a beta test of Nougat for Honor 5c. Yesterday I wanted to leave it and go back to a stable rom but I was unable to find a flashable ZIP of stock Rom so I used FlashFire to flash a update.app firmware package (some **** from Huawei...).
After flashing it I tried to reboot my phone but I just got a Error Mode - Please update your system again. (and Recovery image error + load error)
To solve this I reboot to fastboot and on my computer I tried to flash TWRP with fastboot flash recovery twrp.img and I got a error : remote : command not allowed. I search and search and search on forums but I found nothing.
I tried some other fastboot commands, i tried to boot from a img, ... but nothing, just Command not allowed.
I have a Honor 5c NEM-L51, fastboot is "working" lol, no recovery, no force dload update, bootloader unlocked, FRP lock (idk what is this), i was rooted with Magisk and I flashed the package with FlashFire.
Please help me :crying:

can't boot into fastboot or recovery, but the phone works

i bought from china the redmi note 2 and it came only with English and Chinese, and i wanted to install a global rom for it, in some instruction on xiaomi site/forum they said just download the rom, post in in the phone, enter the update app and there will be 3 dots, well i didn't had those dots, so i tried to flash custom recovery via flashify, it said all good, then i tried to enter recovery, it just doesn't let me(it gave me before the mi recovery, but when i tried to update zip from there it said invalid file).
so right now my phone is boot normaly into this chinese/english rom, everything works, but if i try to enter fastboot or recovery it just restart again and boot into the normal state
how can i reflash the recovery or get into the fastboot?
Install a Miui Developer Rom with root. Download flashify and flash twrp. Next flash your rom
that's how i have lost the recovery, i flashed via flashify the TWRP
i can't install miui developer rom without recovery
You can install anything with the MediaTek SP Flash Tool. Search for it on this forum or on Google.
install MI Flash Tool
then download fastboot developer rom or fastboot stable rom and flash it (not normal rom.zip but fastboot rom)
I have a similar problem - i tried to flash twrp recovery both by flashify and by fastboot flash and the recovery is simply not working. I can boot into fastboot without problems, or i can start the phone normally, but when i try to enter the recovery it just continuously reboots the phone and i have to take out the battery.
edit:
it appears i've been flashing wrong version of the recovery image, i flashed the one from this link and it worked - forum.androidurdu.net/showthread.php?tid=637

Redmi 5 - Bootloop stuck - No recovery

Hello everybody!
The last day my phone got stuck on bootloader screen. It just wouldn't boot the OS.
So I tried to fix that by flashing other rom. I have unlocked it trough MiUnlock.
Flashed in fastboot TWRP(rosy) recovery. It could boot TWRP but after a reboot, would launch MiRecovery.
After that the Android didnt start no more. After a new flash of TWRP I was able to enter recovery. I tried to flash a custom rom. After that the VOLUME UP + POWER wouldnt launch recovery no more (Also VOLUME DOWN+UP+POWER buttons, wont boot the Recovery)
Now i found an EDL mode to flash rom through XiaoMiFlash. Did it, Made the steps from tutorials. That, has changed the device to COM10 in MiFlash which let me try different official roms, and i always get the same error message: cannot receive hello packet, MiFlash is trying to reset status!
Also tried too flash a recovery img.
Tried everything i found on that, nothing worked to get those packets...
My only hope was to fastboot flash recovery TWRP or MiRecovery. And then flash new rom to fix my phone.
Tried many version of Twrp, but no success to actually flash.
I have tried removing recovery via adb and flashing another. Logs shows success but no effect on phone.
Still can't acces recovery mode on my phone.
Bootloop stuck. Shows MI logo and that its Unlocked.
Doesnt work flashing via fastboot - TWRP or MiRecovery images.
My phone is bricked for a week now. Please share a solution if you got one.
SOLVED
Good news. finally flashed chinese version through miflash tool.
had to rename some files from rom.
Flashed through BOOTLOADER.

[Help] Bootloop on Xiaomir Redmi Note 4X

Hello, I'm kind of new at this (this is my first post) so be gentle
So, the last few days I've been trying to install a new rom on my phone (Redmi Note 4X) and the problems started with the model. I only seem to find Redmi Note 4 roms, and as I've come to find, mine is supposed to be the mido one (correct me if I'm wrong though). I have unlocked the bootloader, I have installed and enabled the fastboot on my phone, so the next step was to install the latest TWRP.
There came more problems; I tried doing this through the app and it just wouln't flash it. So I found a guide on how to root my phone and install a new recovery through adb and I followed it. It didn't work. I couldn't find the right twrp version for my phone. When I finally did realise my phone needed mido, I found the latest from the TWRP website. It wouldn't load through adb again. I found a thread about a fixed mido version, which finally worked for me. But my brother who was helping me, and isn't as much of a noob as I am (he has flashed rom and recoveries many times on his Nexus 5X), decided that I necessarily need the latest twrp if I'm going to flash a new rom, so he flashed the new twrp through the old one, and soft bricked my phone (I think). So I'm searching for a guide to unbrick it. (Which I can't seem to find to work at least).
To conclude;
I have unlocked my bootloader
I have access to the fastboot
I tried to flash a recovery
I failed many times, but I managed it
I flashed the latest twrp and bricked my phone
I don't have access to the recovery
My phone is still on a bootloop
I am not sure about which phone model I have
Help!
Thanks in advance.
1. Just check your phone model on its box. If its Snapdragon version (Mido), then just install it via fastboot. (code: fastboot flash recovery twrp-midoxx.img). If you are success, then try to reboot to recovery (fastboot boot twrpmido-xx.img). After booted, then you just manage to rom.zip you want to install. If you don't have it, then download it before from your PC and push it to your phone. Or just enable Mtp checklis from TWRP n copy that file to your internal phone/sdcard. Wipe all/factory reset except internal storage. Then you dan install rom.zip normally. N reboot. (Note: if you are on MIUI and wanted to always stay on it, just flash the file called lazyflasher.zip. n' wipe cache n art cache only then reboot). Flashing custom recovery on stock MIUI Will manage the device Going to bootloop)
2. If you have mediatek version (nikel), searching the fastboot Rom from miui website and flash it normally via fastboot. (SP Flash tool)
Warning: flash the wrong rom file into wrong phone Will make your device brick. So becarefull n knowing what model/code name you have.

Hello and thanks for the reply. I have the snapdragon version, but all I'm asking is how am I supposed to flash the lazyflasher without accessing the recovery? Through adb?

Firstly, enter fastboot mode on your device. Connecting to pc and flashing the twrp for mido. "fastboot flash recovery twrp-mido.img". Then boot to it using " fastboot boot twrp-mido.img". Then you will enter the recovery (twrp) in a second. Copy the lazyflasher into your phone (enable mtp first in Mount option in twrp) that you downloaded from pc. Just flash the lazyflasher.zip and reboot.
And why you don't want to flash lazyflasher when it very easy to flash it using recovery twrp? adb? You mean android debugging? Actually, you cant flash a .zip file into your system partition except through fastboot mode. However, fastboot mode (in cmd) only recognize a .img file. I just try to tell you the easier method to make your device boot up.

As I said above, I can only access the fastboot, and I get errors in the adb when I try to flash the twrp image.

Help me with Realme 7 bootloop no fastboot or recovery available

I unlocked the bootloader succesfully then i tried to root the phone so i downloaded a relame 7 rom and patched boot.img with magisk then i did a fastboot then i typed in my pc cmd (fastboot flash magisk_patched.img) then (fastboot reboot) then i stucked at bootloop and i can't go to fastboot or recovery , Even the pc don't detect my phone, I think its because i downloaded a rom of newer version that i didn't update to it before flashing the patched boot or maybe i typed wrong cmd , Please any help guys there isn't any realme support center in my country, Thanks in advance.
you should have flashed vbmeta.img so that you don't get in bootloop
You mean your phone wouldn't go into bootloader by "Vol. down button + power button" holding from power off state?

fastboot flash magisk_patched.img

Do you mean "fastboot flash recovery magisk_patched.img"??
the correct command is fastboot flash boot magisk_patched.img
Maybe he wrote fastboot flash magisk_patched .img
but I think it would have returned an error

Maybe the rom you downloaded and the base rom running on your device is not the same version, that may cause the error. {Mod edit}

First you all. Say the Model Number. You talk about Realme 7/Pro or 5G...
This issues is fixable. Just need extra tools to bypass Google FRP and a factory images ROM versions. Fixed few devices with the same situation!

did you find soultion of this at now because i also have same problem?
I've done the same thing I accidently typed "fastboot flash recovery magisk_patched.img" and now I cannot get out of the boot loop as there is no way due to messed up recovery + boot. I have been reading about finding and downloading a firmware in zip format that can be flashed with "SP Flash Tool" but when I try I cannot get it to work. The Firmware should be for the Realme 7 5G [RMX2111].
If anyone else can figure it out.... Please help!

It'll be kinda hard. You're gonna have to find a stock ROM - not an OTA update - and you're gonna need to use python to extract the contents from the .OFP file. This should be it. https://firmwarefile.com/oppo-realme-7-5g-rmx2111
basically you can follow this tutorial
the only difference is you have to use realme 7 firmware not C3. this is ofp file for rmx2151 you can extract it with ofp extractor. also I link this guide for RMX2155. its bootloader unlock guide for RMX2155, but you also follow that guide to revive RMX2151 (until step 10 is sufficient, unless you want unlocked bootloader too)
SF Flash tool is a quite useful for flashing/unbrick Mediatek phones. just read instruction more carefully from now

[SOLVED] I think I bricked my Mi 10 - Please help

Hi,
So long story short, I tried to get good phone for someone for a good price, I ordered a Xiaomi Mi 10 from China - But it came with a bunch of Chinese bloatware so I wanted to flash the Global ROM and have Google on there
I added it to my Xiaomi account, unlocked the bootloader (waited 168 hours), then followed instructions from a youtube video (
)
It worked well - I used adb to flash TWRP, and was able to install the Global ROM from xiaomi.eu using TWRP (version 12-11) (filename: xiaomi.eu_multi_MI10_V12.2.9.0.RJBCNXM_v12-11)
This worked well and everything went smooth, and I thought I was done, then I wanted to remove the device from my Xiaomi account, so I did remove the device from my account via Mi Cloud, and then I went to factory reset the phone, and then it just keeps booting into Fastboot.
I tried to hold buttons to boot into TWRP (volume UP and Power) but just goes into Fastboot, I tried to flash TWRP again via adb using "fastboot flash recovery twrp.img" but am getting this error when I run "fastboot boot twrp.img" - FAILED (remote: 'Failed to load/authenticate boot image: Load Error')
Please let me know if there is anything I can do - even to get back to the chinese stock ROM
Thanks in advance
Hi all - I solved the problem by using the Global Fastboot ROM and MiFlash tool - I got a CRC error "update sparse crc list failed" but followed some advice to edit the "Flash.all" script and remove the 2 lines that contain "CRC"
Then the Flash process worked and the phone did boot into Global ROM
The xiaomieu stable version has a problem with custom recovery, so you grabbed fastboot.
if you want to use recovery, you need to boot recovery via ADB with the command fastboot boot recovery ....
Do not use on a stable version of xiaomieu recovery via the restart button to recovery
Actually, one can boot to recovery via restart button, but only after flashing the twrp 3.4.0 little turtle.
However, this recovery isn't able to decrypt the partitions, and could be used for flashing ROMs only from OTG drive.
The one that does decrypt and could be used in "normal" way is twrp 3.4.2.1206, but this one can only be booted as you said with fastboot boot recovery.img
