Flashing Recovery Post Hard Brick

Hey,
I hard bricked my phone (no download mode, no recovery and no fastboot) and then managed to fix it (VIA SRK Tool) and got download mode back.
Now I need to install a recovery, and I cant go and manually check if the TWRP recovery is already installed or not, because if I do go to check and the recovery is not there then the phone will factory reset (and I'll lose all my data).
KDZ Method isn't working, it keeps saying I need to restart my device at 23% (same on two different PCs).
So is there any way of flashing the TWRP recovery through the download mode?
Thanks a lot
(I have a D801, I can get to download mode, factory reset screen and LG logo which then leads to the "Security error" coz there is no firmware in the phone.)

XT1575 Reset Loop

After messing up a rom flash somehow (phone was stuck on a gray screen after logo), I used the stock recovery factory reset function, but after doing so my phone is stuck in an 'erase loop'. The phone alternates between the "Erasing..." screen (with the little droid) and the "Bootloader Unlocked" screen.
I can enter the main menu for recovery mode, but if I try to go into the actual recovery mode (where you can wipe and install from sd/adb) the loop starts up again. I haven't seen this issue mentioned many other places, but the one forum I did find (for a different phone) just said to wait it out (20+ hours).
I was wondering if anyone else had ever encountered this, or if anyone had any suggestions for me.

Try flashing TWRP recovery image using fastboot. I presume you have bootloader unlock otherwise you wouldn't ended up in this mess in first place.
First reboot your phone into the bootloader (POWER+VOL-) from here you can connect your phone to PC and issue fastboot commands.
Code:
fastboot flash recovery /path/to/TWRP.img
After that don't reboot the phone , just select from the already present bootloader the Recovery option... And from there try to factory reset !
If that doesn't work, and the phone doesn't boot (bootloops), you might have the /system partition messed up. At this stage get your hand on the latest Stock Firmware for your phone and flash all the system chunks (no data will be lost, but might need to wipe cache after if you get too many Force Closed)
That is for sure if you want to have stock, you could also try and flash using TWRP a custom ROM, that by itself will restore your system partition ( wipe system before flashing to be sure, by going into wipe -> Advanced -> tick System and the two Cache options and Wipe)
Hope I was clear, ask if you need more step-through details!

Thank you very much, flashing TWRP worked!

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.

I'm sorry for your loss. To me it sounds like something may be physically damaged.

To elaborate a bit further, fastboot doesn't usefully exist without root, stock recovery can only wipe your userdata, and you've already said download mode reboots way too early to try anything. There is no safe way to try anything with the firmware, if it even somehow is a firmware issue. There's the leaked firehose, if you force it into 9008 mode, but that's risky and I have no personal experience with it to give more details.
Basically don't expect it to be coming back.

Without it already being rooted and the dirtysanta bootloader installed there is no fastboot mode on anything (which you would have seen if you had read the OP) but the h918 (which still can't flash with it) and us996, and you still need a working phone to actually set the options in Android to allow unlocking the bootloader.
And I'd put it at like an 80% chance it's hardware failure anyway, since it's boot looping in download mode too.

Try holding down volume down and plugging in USB.......

Same issue herewith...
LG V20 boot loop , restarting again and again , also when USB cable method is applied to enter into the Download Mode , it also restarts after sometime after showing download mode icon etc........

Question Help with Nothing phone stuck in Fastboot mode (A13 Beta 1.5.1)

Hello,
I was trying to downgrade my phone from the beta to Android 12 and it's now stuck in Fastboot mode. Won't let me enter recovery. Tries to boot but just stays on the nothing logo. My bootloader is unlocked. I'm assuming I need the same firmware I was running to reload onto the phone. Any other files needed?
Thank you so much! cheers

I can't enter recovery mode. Only fastboot.

Flash boot and vendor_boot and you'll be right back in recovery
If it's not booting try set active slot to either a or B and flash the images mentioned above

I'm having a similar issue coming off a fastboot stuck device. I guess I managed to delete the recovery mode from slot B so I can't get into fastbootd to flash some of the lower level partitions to make my fingerprint sensor work.
The vendor_image is the recovery?

Did you guys find any solution? I am stuck with my phone stuck in the bootloader mode and I can't seem to do anything.
Here's what I did:
1) Unlocked bootloader while being on NOS 1.5.1 Beta. Successfuly did it.
2) Restarted my phone to bootloader mode and flashed dtbo, boot and vendor_boot from SuperiorOS 11th Feb build.
3) Proceeded to restart to recovery as mentioned in the instructions but instead of restarting to recovery, it restarted to bootloader.
4) Stuck in bootloader mode ever since!
Nothing seems to be working. I have tried literally everything but cannot get past the bootloader. Please help. I don't have any secondary device to use.
