Note 7 stuck in bootloop after failed flashing attempt. Can't get into fastboot. - Xiaomi Redmi Note 7 Questions & Answers

ood morning!
While attempting to flash a stock MIUI 10 ROM into my Xiaomi Redmi Note 7, to downgrade back to Android 9.0 due to some app compatilibty issue, I messed up big time and my phone is now stuck in a loop where the screen turns on, nothing shows up, then it restarts, going off for a few seconds and turning on again.
Power Button + Volume UP successfully brings me to the stock recovery 3.0 from xiaomi.
Power Button + Volume DOWN fails to bring me to the fastboot mode.
If I select the Connect with MIAssistant in the recovery the phone will show up as "sideloaded" after using the command adb devices, but the MIPCSuite app does not see it and the command adb restart bootloader also fails to bring up the fastboot mode, it just gets stuck in the loop again.
More context on what went wrong and caused this: I followed an online tutorial to flash a rom using the MIFlash app, so I unlocked the bootloader and tried to flash the rom usin xiaomi's tool. I got a failed to check sparse crc error code and it went downhill from there when I tried to fix things reading multiple threads on the issue. I tried deleting some lines from the flash_all.bat file and tried to flash it again but then the flashing process went seemingly forever so I aborted the operation and now this loop happens. I tried a few more times but with no success.
The first time I tried to use the tool I used the clean all and lock option so I'm not certain if the miflash tool locked the bootloader regardless of the outcome of the flashing attempt.
Is there hope? Can I fix this phone if I only have access to stock recovery and nothing else (although it shows up in adb devices but can't get into fastbootmode) ?
Thanks a lot to anyone who took the time to read and possibly help.

I finally managed to fix it through the Emergency Download Mode (EDL). It requires Xiaomi Authentication which I bypassed using this guide: https://www.droidwin.com/fix-mi-account-authorization-unbrick-xiaomi-edl-mode/
With that setup I flashed a stock rom using the MiFlash tool.

unaccessible fastboot / recovery

Hi,
Currently on 2.22.40.54 firmware, and successfully rooted it, but with a wrong root method. Therefore I lost camera access. Followed this guide , and flashed the 2.22.40.30 fastboot / recovery (which was successful), but the firmware flash didnt proceed, (had to restart), which resulted in not able to access fastboot / recovery. Tried flashing a new recovery tru xFSTK, but encountered the driver error and the ASUS Flash Tool gives me "serial number not found" error... I usually get the USB logo on start up, but sometimes I get a normal boot (which is nice).
Now, what is the best way to recover my recovery / fastboot? I'm willing to try everything except bringing it to a Service Center.
turn off devices and then pres power buton and vol. up y will see asus logo then pres only vol. up .. if it will works please write there

a6000 shut down during MIUI flash, won't boot into recovery

Hey guys I was trying to flash MIUI 8 on my a6000 lenovo. Bear with me because I'm new to this so I might have screwed up.
Rooted and installed TWRP perfectly. Phone was running kitkat.
I then, through TWRP tried to flash MIUI 8 from http://forum.xda-developers.com/lenovo-a6000/development/rom-miui-7-lenovo-a6000-a6000-t3355692
After first swiping right to install the zip, i got an "error executing binary in zip" error. Wiped dalvik,etc. again and tried again and then I got a MD5 file not found "warning". It was not in red letters and after that message there was no progress bar or anything and the phone just stopped responding. I assumed it wasn't working and few minutes later took the battery out. After trying to boot again it would give me the "mi.com" boot screen (not the default lenovo I used to get) and won't boot into neither recovery nor normal mode. (for recovery boot I'm trying holding both volume buttons and the power button at the same time. perhaps that is different now?)
I'm guessing the flashing was going on and i interrupted it. How can I fix this?
Update: It boots into MIUI now however pretty much nothing works as expected. It wont even go into settings. Recovery still seems botched and i cant boot into it.
TLDR: Recovery broken cant boot into it. Can boot into MIUI with very limited capabilities. Cannot select USB debugging and "adb devices" won't find the phone. What can I do?
Alright nevermind guys I managed to fix it. for anyone wondering or having the same issue, i tried many things but what I think worked is this:
Turnt on my phone in fastboot mode (hold volume - and power button) , connected it to the computer and used command "fastboot flash recovery recovery.img" to flash the old TWRP i had on my computer. After that I managed to boot my phone in recovery mode and reflash the rom properly. The weird thing is, my phone could not be recognized by the computer and "adb devices" gave me nothing back so I thought using any fastboot command wouldn't work. Oddly, it did and it flashed TWRP back into my phone.

A2017G only EDL mode available, need help with brick

Hello
Long story short, i digged out my axon 7 to use it with some music apps.
I wanted to return the phone to stock firmware, it had unlocked bootloader and running a custom nougat rom (AEX i think).
I followed this thread: https://forum.xda-developers.com/axon-7/how-to/guide-axon-7-universal-unbrick-t3814413 and flashed full EDL package.
Now when i try to turn on the phone, or enter recovery i see the boot logo and quick flash of the commandpromt with a broken droid and the phone turn off again.
I can still enter EDL mode and flash the phone.
Any ideas how i get it up and ruunning gain ? preferably on stock firmware
Thanks

Use one of the less archaic methods:
Download "EDL Tool" from the ROMs, kernels, development section, along with an EDL package that goes with your phone model. Put your phone in EDL and just flash it with that tool. after that, if it still doesn't boot you have to format data, because you might have conflicting data. If you can't do it from EDL Tool (i think you can, don't remember) just enter the recovery with Vol+ and Power and make a factory reset
My story is very similar and now i'm stuck in EDL mode. I was able to flash stock Oreo B02 EDL package successfully and boot into OS. But after i was trying to unlock bootloader and reboot to recovery, ZTE logo appears for a second or two and then following error message starts looping:
(broken droid logo)
No command
Supported API: 3
E:failed to mount /cache: Invalid argument
E:Can't mount /cache/recovery/last_locale
EDL mode works but if i flash EDL package or boot/recovery again nothing changes, i still get the same error. Can't boot to OS any more and recovery does not work - screen just stays black.
So what are my options now to get it to work again?
From some other threads, I believe you could try to EDL flash Nougat instead of Oreo, it would work better.
https://forum.xda-developers.com/axon-7/help/help-edl-factory-restore-stuck-device-t4031619
I did that already but no luck, i still end up with the same error.
Is there some way to reformat or clean up internal storage completely in EDL mode? It seems that some garbage left behind by trying to unlock bootloader is surviving even EDL ROM flash and breaking OS boot.

According to other threads, the problem could be due to "sparse" structure while flashing.
I suggest the following:
- Use Axon 7 EDL toolkit to flash latest official TWRP recovery (for Oreo a specific TWRP would be requied).
- Inside TWRP then wipe data/factory reset and at the utmost Format data. Then retry to boot.
- If not OK, reflash with EDL full ROM and try again.
Already done that for several times with O ja N EDL rom's but no luck. Can't get to recovery nor make system to boot.
Did you successful unlocked bootloader?
If not, I would recommended Axon 7 EDL Tool by djkuz, flashing nougat edl package and unlock it through the options.
Can you get into stock recovery after flashing EDL package? It supposed to have a format option for userdata and cache.
Did you try to get into fastboot mode? Power + Vol up buttons if i'm not wrong.
If so, you could try to format these partitions.
fastboot erase /cache
fastboot erase /data
I have experienced the same problem but I have resolved flashing, with Xiaomi MiFlash (sometimes I use this program because occasionally flashing EDL packages with AxonEDLTool, it gives me problems like this) this package Axon7_RR-O_B32-B10_TREBLE-Ready_Oki20180803_FULL_EDL.
With this EDL, if the flash is successful, you will find NFound recovery 3.2.1-7 installed with which you can make a complete wipe and / or format them with the file system you prefer.
Afterwards, using MiFlash or EDLTool at your discretion, you can flash the EDL of the original system if you prefer.
I'm not an expert but this has solved my problem.
To unlock the bootloader, if the unlocking with EDLTool does not go well (it happened to me just yesterday while I was installing a Rom on another Axon 7), you can use Axon7ToolKit 1.2.1, it always worked well for me.
I hope it can help :fingers-crossed:.

Hi, just want to let here my solution for the same problem, it may help others.
I tried to flash A2017G_B10_NOUGAT_FULL_EDL and A2017G_B02_OREO_FULL_EDL but always getting the Can't mount /cache/recovery/last_locale error, phone completely bricked.
So I flashed A2017_B13_FULL_EDL_UNBRICK_DFU using MiFlash through EDL, you can find this here: https://forum.xda-developers.com/axon-7/how-to/a2017-4th-category-brick-repair-manual-t3585898 (if your EDL mode works fine there is no need to disassemble the phone as shown in that tutorial)
Now the phone is completely working, recovery and system, but everything in chinese.
Then I flashed A2017G_B02_OREO_FULL_EDL using MiFlash through EDL, and now everything is working and in english
Thanks a lot for the tip! A2017_B13_FULL_EDL_UNBRICK_DFU did the trick and unbrick the phone.
What i did:
1. used MiFlash to flash A2017_B13_FULL_EDL_UNBRICK_DFU
2. after that A2017G_B03_OREO_FULL_EDL
3. reboot to recovery and performed factory reset
First time I did not perform the factory reset and got stuck on the boot picture without the reset function (power button did not work). Drained the battery and performed factory reset and got the phone working again.
update:
Phone is not stable on B03, some apps crashing from time to time for no apparent reason and also soft reboots happening randomly.
Now I got stuck on the Axon boot screen again after rebooting the phone manually and waiting for the battery to drain ...
i did not install or perform any custom action to the system, just regular use and apps, but it is still acting up badly.
I was planning to use this phone as a secondary handset because it is actually a very nice piece of hardware but now i am starting to have second thoughts about that.

MI A1 can't boot in either stock or custom rom

Hi all,
I hope someone can guide me through. My MI A1 device has suddenly stopped booting for no reason. To fix up I tried many thing but with no luck.
here is link to one of the thread I have followed
Reddit thread
This guy exactly had the same issue as mine but on different model and I followed all the instruction as in this thread.
Summary of things I tried so far (Including instructions from the thread I mentioned) :
- Try mi flash tool to flash stock rom (Which succeeds and nothing actually works )
- Tried my luck with lineage os 17 and GPAPPS but no luck. (Interestingly, when I Install LOS and I the reboot device, it boots in LOS recovery fine but when I try to boot system it just keep rebooting and then finally stops at charging screen.)
PS. One more observation, when I flash it with MIflash tool with stock rom and it boots up for the first time, an intermediate screen with circle logo and erasing text appears just like when we get update screen not sure why!
Guys, this is my last bet on XDA. I almost wasted my whole day searching for solution on #Youtube and other forums, nearly read a ton of things but still no luck!
Please Help!
UPDATE :
Here is a little more progress,
So, I tried flashing the original stock rom boot image with fastboot
Code:
fastboot flash boot boot.img
and as usual first it just got rebooted with no luck but later somehow booted the device. I tried the same with recursion OS ROM and then again flashed boot image and just like prev attempt it rebooted first & then booted normally.
Also, when device was booted normally, I received a call and when I tried to pick it, It just got rebooted and I am where I started!
I really don't get the point why it boot when I manually boot it with fastboot and its not able to boot itself.
Anyone knows, why this is happening? Is there a way to clean whole and then install? am I doing something wrong here?
Update :
Yes, confirmed when I flash the boot image from fastboot it does boots up. the only problem is after a few seconds/minutes it just reboot and goes back to problematic state.
This thing is really pissing me off! Can someone help?
Update:
After a few more attempts now, it seems like the device is completely broken! It only boots up in fastboot and does not even boot in recovery ( Volume up + Power)
I also tried with pushing twrp recovery image with fastboot but even though the command succeeds the device just reboots with MI logo continuously.

asus zenfone max m1 recovery, rom not working. help

Please HELP
I am writing here the whole story.
I unlocked the bootloader of my Asus zenfone max m1 (3/32GB) using the unlock tool which I downloaded from Asus's website.
Then, I went to fastboot mode and flashed TWRP recovery and then tried booting into it through the cmd screen using fastboot boot twrp.img command and it worked.
Then I followed a really good tutorial and flashed the pie firmware, Pixel Experience and magisk and ZIPs in order.
And it showed no error, everything was fine and then I clicked on the reboot system button, it rebooted the system but the phone was stuck at the google logo with a loading bar and didn't go beyond that even when left for 30 mins and I tried rebooting the phone multiple times and that did not help. the phone was stuck at the google logo every time.
Then I turned off the phone and tried going to TWRP to flash the pixel rom again but the phone only went into fastboot mode, it never booted into recovery even though I tried multiple times(I was trying to boot into the recovery through the volume and power buttons, not through fastboot mode).
I flashed the phone's recovery multiple times and also the boot image (I even tried flashing the stock recovery) but the problem is that everything goes fine in the terminal, it shows that it flashed the img file successfully and it is finished but the commands like fastboot reboot recovery don't work at all, they all just reboot the phone normally and the phone just shows the ASUS logo for few secs and then turns off.
Note: I used fastboot erase commands to remove the pixel experience rom and now I'm only left with a phone which boots only into fastboot with no rom and I don't know about the recovery because it shows that it flashed but it never opens.
Hi
I am having a similar problem in that I can oly get into recovery mode with adb reboot recovery. I researched and tried all possibilities with the phone key but I can only go into bootloader mode.
After flashing recovery successfully (?) I can only boot the phone normally and that seems to reinstall the default recovery manager.
While researching I found that there are some discrepancies with the ID out there. While my phone is a Zenfone Max (M1) with the ID X00PD some places (TWRP) confirm that but others refer to Z555KL.
Did you get any further?
