Hello guys.
I have been in the android world for a while, but just got this device.
I had tried to install twrp with no success. I already have bootloader unlocked by me with no issues, following a tutorial here. When I flash twrp it shows success but when I try to go there ñ, it just goes to miui recovery. When I boot directly from fastboot with:
Fastboot boot twrp.img
It goes there with no issues but of course, data is encrypted. So I want to install it in order to format my data and be able to root. Any ideas?
I researched and found that one way is to install a dev rom, but I really want to remain on stable one.
Thoughts?

Put a copy of twrp.img in your sdcard.
Put other copy of twrp.img in adb folder of your pc.
Type from a cmd with admin rights with device in fastboot mode connected to pc fastboot boot twrp.img and when you reboot to twrp slide allowing modifications and then flash your twrp.img through same twrp recovery
The first command will do that device can boot to twrp but it´ll not flash it in recovery partition.
The second action will flash it permanently onto your device.
Probably you´ll need to format data in order to can reboot to system again.

Thanks! I solved it after taking a look for a while. I do not have an sdcard, so I flashed it and then fastboot booted it, then I reboot recovery to make sure it was flashed and then formatted data. I worked flawlessly!

Hey guys,
i've got the following problem: Unlocking the bootloader, installing TWRP and other ROMs went hassle free and worked flawless until recently.
Now, after having to reflash a clean OOS 2.2.0, it says the bootloader is locked again. TWRP is still installed. When trying to unlock the phone, it just boots to TWRP (which shortly prints an error message, but its too short to read) and shows that the bootloader is still locked in fastboot.
The problem is similar to this one:
https://forums.oneplus.net/threads/opo-back-from-the-dead-story-of-a-brick.144155/
In that thread, a solution is pointed out -- namely, this one:
http://forum.xda-developers.com/showpost.php?p=54251992
The script is for OPO only, so I'm left in the rain. Do you guys know any other way out of my misery?

Install stock recovery and unlock bootloader again...
I'll give it a try. Would you point me in the direction of where to find the recovery.img for that?
EDIT: Phew, did it. Your way worked. I can't even count anymore how often I wiped and reflashed the whole thing in the last 24 hours...
I have exactly the same problem. I have the stock recovery file. Can i just flash it with TWRP ? and stock recovery will be loaded? because i can't use fastboot to load i because its locked
reboot into twrp
copy Stock_recovery.img to device folder
go to install
at the bottom select install image

Your phone is in fastboot mode, not download mode. Small, but distinct difference.
Since you've installed a custom ROM, your bootloader should be unlocked. However, it may be a good idea to issue the oem unlock command through fastboot anyways. Use "adb reboot bootloader" and "fastboot oem unlock" to ensure that your bootloader is unlocked.
Now, since your phone is in fastboot mode, you can do one of two things: 1. Flash a custom recovery and restore your device to stock, or 2. Flash a custom recovery and continue using a custom ROM. Either way, you will need to install TWRP or another custom recovery image of your choice. The TWRP thread is located here: http://forum.xda-developers.com/tmobile-lg-v10/development/recovery-unofficial-twrp-t3239740 Since you're already in the bootloader/fastboot mode, all you would need to do is download TWRP and use "fastboot flash recovery twrp.img" and then "fastboot boot twrp.img" to install TWRP. Please note that the 'twrp.img' will vary depending on which version you download, it will probably look more like 'twrp-2.8.7.1-h901.img'. You can just rename the file or use the full file name in the fastboot commands.
Once in TWRP, you can flash whatever ROM you want. To restore your phone to stock, go to this thread and flash the .zip in TWRP http://forum.xda-developers.com/tmo.../lg-h901-stock-images-device-restore-t3241170 after doing the standard wipe procedure. :good:

I'm kinda in the same boat now except that I already received the replacement device. Need to re-lock the old V10, but adb won't recognize my device at all. Any more option when that's the case? I can get into both download mode and fastboot. Phone is recognized by LGUP in download mode, but not by adb in fastboot mode for some reason.
(I've verified connection and driver using the other V10, the other V10 is recognized just fine)

Yep. Your phone boots and everything, correct? Just factory reset it (Settings > Backup & Restore > Factory data reset). After its been reset, unlock it, turn on Developers Options, and enable USB debugging. After usb debugging is turned on, connect the v10 to your PC and be sure to hit "Always allow" when prompted by your phone. ADB should now be able to see your device.
If you can't get it to boot up, try restoring through LG UP/Bridge. I don't use any of LG's software, so I'm not sure what those apps can do and whether or not you'll be able to restore through them.
If nothing else, your phone is recognized in fastboot mode, so you can always manually flash the stock system images as well. You want to use the "fastboot flash boot boot.img", "fastboot flash recovery recovery.img", and "fastboot flash system system.img" commands After downloading the stock system images located in this thread: http://forum.xda-developers.com/lg-v10/development/lg-h901-stock-img-files-boot-recovery-t3238638
If you haven't ever flashed system images from fastboot, please read this first, as I am not responsible if your phone turns into a paperweight! https://developers.google.com/android/nexus/images#instructions While the instructions are for nexus devices, it works pretty much the same, except you'd want to use the individual commands instead of a flash-all script.
Hope this helps!

Thanks for the follow up! No the phone would not boot at all and kept stuck at boot loop. I ended up just doing the OEM Lock and call it a day, the old device just won't boot to anything at this point.
I tried fastboot flash recovery recovery.img but it's giving some kinda kernel panic message and I was never able to get into recovery. This reminds me of the time when my Note 3 eMMC was fried, it wouldn't give a device ID to adb.
I think I am in the same boat too. I've been OEM unlocked yet recently my phone won't keep the TWRP recovery and keeps putting me into bootloop. I can't install a ROM and only thing I can do is fastboot mode. What did you do OEM lock the device? I am hoping that solution will get rid of that message bootloader unlocked during the bootloop and then I can try and get it serviced.
How can I lock the phone back after unlocking bootloader, rooting, installing Xposed?
Wipe installed custom ROM (System+data+cache+dalvik).
**Internal storage optional (You may have to flash TWRP again though).
Install MIUI recovery ROM pack through TWRP. Run MIUI initial setup. Reboot to fastboot and flash stock recovery, you can find stock recovery in MIUI forums. After that check for successful flash and successful system boot. Only then run the fastboot command to lock the bootloader :
fastboot oem lock
**Do not lock with TWRP. You'll hard brick your phone
***After flashing MIUI in TWRP flash lazyflasher or your device will be stuck
If you don't understand the complications in this method please ignore it, am sure there are some easier ways using MiFlash. Check MIUI forum for relocking and recovering to MIUI. If you wanna come back to the world of custom ROMs and Mods XDA is the place.

Thank You
BTW If you have the time could you write this more in steps like for a noob. If not it still kicks a$$ and thanks for reply
First you need to get rid of your current ROM and it's data. For that boot into TWRP and select wipe, in the list of partitions displayed select :
•System
•Data
•Cache
•Dalvikand confirm wipe. This step removes the ROM and data associated with it. Now the only thing you can access is TWRP and fastboot.
Also during wipe you can also select to wipe Internal Storage partition but after you do this you may lose TWRP also at the next boot. Now your phone can only boot into fastboot mode. So if you did wipe your internal storage also flash TWRP again from fastboot. If you ask how..:
•Download TWRP recovery from here
•Copy the downloaded file to any folder on your PC.
•Install ADB and fastboot drivers on your PC if you haven't.
•Reboot phone into fastboot mode(Power + Volume down) and connect to PC.
•Go to folder where your placed the TWRP image file.
•Open command prompt in that folder (Shift+right click mouse, open command window here)
•Type the following commands without the quotes :
" fastboot flash recovery twrp-3.2.1-0-mido.IMG "
•Now try rebooting into TWRP (Power + Volume Up). If you followed the steps right you should be able to.Remember this step is only if you decide to wipe internal storage also else it is completely not necessary.
OK now that you are left with a phone that only has TWRP we need a ROM to boot into, in your case you want a MIUI ROM. Download latest stable MIUI recovery ROM pack from MIUI website or just google if your having trouble finding it. For MIUI ROMs to successfully boot on a custom recovery you need to flash an additional zip called lazyflasher else your phone will be stuck at the MI logo. I'll attach the zip below. Okay so now since you have the required files copy them to your phone's internal storage.
Boot into TWRP and install the MIUI ROM zip first and the Lazyflasher zip after that. Reboot into system and phone should enter MIUI initial setup in some minutes(be patient MIUI initial boot can be long). Finish the setup.
Now you need to flash the latest stock recovery of your phone. I don't have it with me now so a simple google search will do the work. The procedure for flashing the recovery is the same as flashing TWRP which I have mentioned above. The only change you have do in the fastboot command line is the file name of your stock recovery.
After flashing check for successful boot, only then proceed with the relocking procedure as follows:
•Boot phone into fastboot mode
•Connect to PC
•Open Command prompt
•Type this fastboot command without the quotes :
" fastboot oem lock"•Once done reboot your phone.
Now you must have a relocked phone.
**Never relock your phone with any custom mods like custom recovery, custom ROM or even a MIUI which is rooted. Also be on 100% stock configuration before relocking device. Failing to do so will result in a hard brick.

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.

Share your error please.
Try fastboot boot twrp.img
Hi, I'm having some issues trying to install the newest update of A10.
I was on A9 with unlocked bootloader, root and twrp of recovery.
I first tried to install the .rar image via recovery but I couldn't find in the memory, but I already wiped system vendor and data.
So when I rebooted to try if the file was there or not, there was no recovery anymore.
Now I'm trying to flash the newest rom via fastboot but through the flash_all.bat it gives me fastboot tz_a error, so I'm trying to install a recovery through fastboot using this guide https://forum.xda-developers.com/mi-a3/how-to/basic-guide-to-flash-recovery-rom-via-t3989603 but of course it doesn't work and when I reboot it doesn't enter the recovery but always in fastboot (even tho I press the + button).
What should I do now? Is there anyway to erase everything and install a clean OS from 0 just from fastboot? (Without the flash_all or miflash because it doesn't work)
P.S. I don't care about the data, I've done a backup of all my important files before
Thanks for the help

First, you have to understand what you did. You wiped your system and vendor image, and didn't installed a newer one afterwards, you didn't wiped your recovery (it's inside boot partition).
Further, .rar files will not be flashed through TWRP, .zip must be used instead, with proper format, there must be a compatible flash script inside.
You can't access your recovery, just because you wiped system; inside your bootloader there's a component responsible to manage the slots, bootctl and by default if it detects a corrupted or invalid system partition, it will always boot onto bootloader mode.
As for the tz_a error, you must unlock critical partitions flashing, just because, tz is a critical partition, thus, run in Fastboot:
Code:
fastboot flashing unlock_critical
If you want to know your current state, use:
Code:
fastboot oem device-info
Your current slot is blocked by bootctl, but this doesn't mean your inactive is too, so, use:
Code:
fastboot set_active other
And reboot into TWRP again, that is, if you do have it installed in your inactive slot.
Fastboot/ADB and other tools, you will find it in here:

Thanks for the help but I managed to get into the recovery and install the rom via fastboot, the thing I was missing was a recovery working for Android10 (even though I remember recovery doesn't have nothing to do witg the installed OS), so I managed to install the recovery and root, and everything went fine after a few tries between various guides. Probably my partitions now are all messed up, but if I boot normally it goes into system (slot A), if I boot into recovery it goes into twrp and also works fastboot. Probably I also installed the OS on slot b, but I don't care as long the first partition works well
