Lg k7 x210 wrong root hardbricked

Hello guys and congratulations for the forum.
I have a problem with a LG K7 X210: I accidentally booted with Aristo 2 Boot and now the LG logo remains fixed and does not turn on.
The only accessible mode is fastboot or recovery mode.
I tried to flash with fastboot flash boot, cache and recovery but it still does not work. I found this version MT6580__lge__LG-X210__m13g__5.1__ALPS.L1.MP6.V2.19_ARIMA6580.WE.L_P42
If I try to flash the preloader or to unlock unroot oem i receive FAIL.
If I try with flash tool, it does not recognize it.
I kindly ask you for help, thank you
There's still no solution I'm still with the HardBrick...

[RS988] Help with brick phone

A few years ago, I ended up bricking my LG G5 RS988 variant, by trying to flash a stock rom, so I can remove the root, and everything else to give the phone to my brother. However, by flashing the wrong rom, I ended up being in a loop where the phone would start up, and 2 minutes into the set up screen, it would restart and be in a never ending loop. I remember trying to fix this problem, and made it worse by probably erasing access to my twrp recovery(can't access the recovery anymore don't remember what I did), then I gave up. I decided to try again to see if I can bring back this phone from the grave so I was wondering if someone could lead me into the right direction. I have the uppercut tool, the lg flash tool, and the drivers. Also in the uppercut tool I do see the version of my phone is RS98821d and I am trying to flash a RS98811c_00_ARB01.kdz. Also another thing to note, my phone automatically boots into firmware update mode(download mode I believe?). Also I have looked into the all in one lg g5 forums, and other forums of restoring their phones, but nothing works with what I tried on my rs988, is their someone that can lead me to the right direction?
Can you do this when you start the phone to get into fastboot?
Code:
adb reboot bootloader
If so, you should be able to get TWRP back up and running:
Code:
fastboot flash recovery [path to twrp image on your pc]

Bootloader unlock V30+ L-01K

Hello everyone..
I just got hands on LG V30+ carrier device from ntt docomo model number to be exact L-01K It's network unlocked and using adb debloat i have managed to get rid of almost docomo japan apps.
But i am stuck on android 9 pie. I tried to unlock bootloader official way but my device doesn't go for fastboot. I was wondering someone had this device and whether if it's possible to unlock and flash custom recovery..thank you
before you flash anything to your L-01k you need to backup the modem partitions with LG UP.

If you have no backup of the modem, you will lose network and there's no firmware for the L-01k anywhere on the net to restore... ask me how I know..

Here is elf file if you dont have. You can go to qualcomm mode by plugging in usb cable in mobile and press volume - and power button and when black screen show keep pressing volume +. you also need to install qualcomm drivers to detect mobile in windows.
Thanks a lot for the files and advice! Will try to restore the modem now..
dont restore ftm i mentioned it by mistake.
I can't figure out how to flash the files back using QFIL. I was in download mode volup then connect USB, same as you do it with LGUP). But that didn't work. QFIL says "Download Failed switch to Emergency Download Mode".
I also tried flashing the modem.bin with TWRP (backup in TWRP, then replace modem.emmc.win with modem.bin and rename that accordingly, then restore backup in TWRP. But that did not work (SIM Card not recognized and no IMEI). Then I flashed back the original modem.emmc.win backup to fix sim card and IMEI.
I think I am missing the XML file for QFIL?
first install qualcomm drivers.
plug usb cable to pc and mobile. hold volume down and power button at same time and when black screen show on mobile keep pressing (don't hold) volume up without leaving other buttons.
when qualcomm mode is detected > run qfil and select port and than > select flat build and > elf file in programmer path and > select ufs storage type in bottom right.
then go to tools > partition manager and there you can find all the partitions first backup and than restore which i said before.
these backups will not work in twrp i think.
don't mix this with download mode in which we can go with just volume up and put cable in pc. if you don't know please google it first its qualcomm mode.
if you have fastboot try this command in fastboot:
fastboot reboot edl
if that works than just follow other steps. to quit this mode press volume down and power button for few seconds. in this mode screen just stay black and nothing will display on your screen.
OK found a youtube video on how to get into EDL 9008 mode:
- Connect the smartphone via USB to the computer.
- On the switched-on smartphone, hold VOL- and POWER
- As soon as the screen turns off, keep holding the VOL- and POWER buttons and simultaneously press VOL + quickly.
- The smartphone will have a black screen, and in the device manager on the PC will be "QUSB_BULK_CID: xxxx_SN: xxxxxxxx" or "Qualcomm HS-USB QDLoader 9008 (COM x)
OK, that worked for me (windows device manager reported "Qualcomm HS-USB QDLoader 9008) , but when I wanted to use the partition manager in QFIL i get the "Download Fail Sahara QSaharaServer Fail: Process Fail "
I'll try this now:
-downgrade to Nougat H930 KDZ ( H93010v_00_OPEN_EU_OP_1120.kdz)
in fastboot: (Using the modem.bin, modemst1.bin, modemst2.bin from L-01k QFIL dump)
fastboot erase modem (enter)
fastboot erase modemst1 (enter)
fastboot erase modemst2 (enter)
fastboot oem lock (enter)
fastboot flash modem modem.bin (enter)
fastboot flash modem modemst1.bin (enter)
fastboot flash modem modemst2.bin (enter)
EDIT: it didn't work
But at least I know now how to get into Download Mode from a Bootloop:
1. Connect USB to PC
2. press Vol+, Vol-, Power until the phone restarts with black screen
3. immediately release Vol- and Power and keep pressing Vol+
.. voila.. Download mode
did you add the v30 file in proggamer path in qfil which i provided and changed the storage type to ufs?
yes, I used that firehose V30 file and I verified that storage is set to UFS.
have you fixed it?
nope, but after flashing the modem with ADB and also trying the V300k Korean ROM, I have learned how to fix a near bricked V30 by using 9008 Qualcomm unbrick mode back to life .
I think the only way to fix this is if a L-01k KDZ is released or someone manages to root his L-01k without overwriting the modem and uploads his complete TWRP backup.
Thanks guys for ur help. It seems like no bootloader unlock for my LG L-01K. So modem backup didn't work. I'm so sorry to hear that. I wish i had rooted my device. But i can't even unlock the bootloader. I want to try custom roms so badly. I guess i have to stuck with android pie. Thanks again.

do you have wifi working and your imei is not null?
wifi works, IMEI exists, says Sim card 1 is "PERM locked".
I'm on H93020d_00_OPEN_EU_OP_0326.kdz now.
The same Sim card works perfectly in my LG G8s

Debloat Japanese Apps like Docomo Contacts App from L01K V30+ ?
How did you do that using ADB ?
With or w/o Root ?
Can you or anyone explain ?

Question Help! My Oneplus Nord N200 5G cellphone is bricked.

I am currently trying to install LineageOS on my phone. I personally have never unlocked or reinstalled a new operating system on my phone. I looked on some XDA forums for some guides and i found one and followed the steps. I unlocked my phone and I installed a custom TWRP because I was trying to downgrade the phone back to android 11. Once i was done flashing the file to the phone and rebooted it doesn't boot anymore and only gives me a booting screen for a few seconds after I hold down the power and volume up button for a few seconds nothing else works. I have use the MSM tool and put my phone into EDL mode and it detected the phone with a black screen. Every time I use the tool it works till about 18% then it gives me a Sahara communication failed error and then my phone gets out of EDL mode.. I installed all the drivers needed on my PC and used multiple USB 2.0 slots but it still fails. Any help would be appreciated.
There are warnings in the TWRP thread for the N200 that it is broken and should not be flashed.
I have written an easy to follow guide here to downgrade to A11 with Fastboot Enhance.
Unfortunately, now that you have used MSMTool on the phone, it is now bootloader LOCKED. This tool should be the last resort only if you are already hard bricked. You could have gotten the phone into fastboot if either boot.img was still intact and re-flashed the rom with a still unlocked bootloader. The phone will change slots after so many failed boots.
Now that your boot loader is locked, the only tool that can modify the phone is MSMTool. If you can get into Recovery, do delete user data and try again.
Otherwise, you will need to get an RMA and send phone back to OP.

Sorry I should have written more details but I currently have a hard bricked device. It will not boot and It failed to boot like 20 times. It will not enter fastboot or even get past the logo when you first turn it on. I did use MSM tool after it wasn't letting me into fastboot. Thanks for the help and I will send it back.
