Hello Forum,
well I guess I kinda soft bricked my OPT as I somehow managed to wipe everything (with TWRP). Of course the Device won't boot a OS, fortunately fastboot and TWRP is working but no matter how I flash a ROM (via recovery or via fastboot) no data gets written to the phone. For example if I open my phone on the computer there is only one folder, the TWRP folder.
I already tried several toolkits and fastboot images. (for example)
Any help is really appreciated thanks
I was in the middle of a restore in twrp and the phone shut off in the middle of the restore (while restoring recovery), and had such, my android system will no longer boot, nor can I get into recovery. It simply goes into fastboot mode and that's all. Is there a way to flash twrp (Archlinux?) using fastboot/adb?
Thank you in advance!

Depends on what variant you have. If its a dirtysanta one while in fastboot do
Code:
fastboot flash recovery (twrpimgnamehere).img
and it will install the twrp image you have downloaded. If you are on TMO you need to revert to stock using a KDZ and then re root.
Fastboot commands aren't working on the H918? My model... -_-
What's the difference between recowvery and dirtysanta?
OK. So let me ask this then. If fastboot commands don't seem to do much on the H918, then how does one go about backing up the internal storage before being formatted? Is there like a dd command to copy everything over? Or will the phone still attach storage to the PC when attached, even in fastboot?
In other words, how can I backup my internal storage before reseting to stock?

The difference between recowvery and dirtysanta is multiple things. One thing is the fact that recovery goes after the recovery directly and dirtysanta replaces the bootloader itself. IF you use dirtysanta on a H918 you WILL BRICK. non recoverable. Dirtysantas boatloader is a debug bootloader that has full access to the phone. H918 bootloader only has limited commands available.
The other difference is how the methods goes about actually doing everything. Jcadduonos recowvery attacks recovery uses scripts to start a factory recovery installer/updater but makes it install a temp root instead of a recovery then the device has access to fully install a twrp image. Dirtysanta skips that and attacks the bootloader directly by replacing a higher level function of the phone temporarily that has access to the phones bootloader(for some unknown reason) and replaces it with the debug one. Once the debug one is in the device is able to be rooted like any other device with an unlocked bootloader since it has full access.

You don't. you can copy everything manually but If you backup the data partition(which has your internal storage inside) it will not be usable on the device after you root. If you do manage to back it up then restore it afterward since the device itself is normally encrypted and is now decrypted the settings and stuff will cause crashes and force closes.

Very interesting how different the two are and how they work. Very interesting indeed.
As for the data partition, mine is already decrypted as is (was rooted already and tried to install a cm rom to test; ended up glitches during restore). But I have no intentions on restoring an backups. I simply want my photos, saves, books, etc off the actual internal SD storage (not my external SD card, obviously).
My question here I guess is, will the internal storage mount while in fastboot mode the same as if the phone was on normal (adds a new drive (win)/mtp link (unix))?
I just want to copy and paste all the files off the internal storage on to my unix desktop. Then format the whole phone and start fresh again.
*bump*
I have tried to access the SD card while in fastboot mode. Absolutely nothing I do can make the PC see the internal storage on my V20. I have some files for my job on my internal SD card (NOT my external SD card, but the actual built in storage), that I absolutely, positively cannot afford to loose. These files are for my job. If I loose these files, I will loose my job.
Please, can someone tell me how to access the SD card in fastboot mode? It's really really important.
If anyone, at all, has any clue or any ideas on how to access the internal storage or how to restore my v20 without a full reset, then please please please help. Hell, I'll even be willing to donate some money to whoever can figure this out for me. Seriously, it's really that important that I get my files off the internal storage.
Thanks to anyone who can help.
P.s. I have access to Windows and Linux computers.

can you let it boot up and will it just hang on the lg logo or is it rebooting into fastboot?
really my only advice would be try letting it hang on lg logo and see if adb is present, furthermore you can get a adb always moded boot.img and push that to the phone using fastboot then see if adb is a option.
If so you can do the adb commands to pull the userdata portion off the device the same way the system dumps are done i believe, but the sad fact is its probably all currupted anyway from your restore you were trying.
The other option is push recovery again to device, and then try a dirty flash of the stock rom, in hopes it can get the system partition back up and running,
furthermore, worst case wipe all and flash the rom, once its back up and running, download diskdigger from playstore and see if it can recovery the deleted stuff, or try the phonedoctor program for windows that runs against your internals and trys to recocvery stuff..
The biggest question is why were you flashing your device without saving stuff thats "soooo important and can cost you your job" ? seems like a oversight on your part really, and a lesson learned. Backup work stuff always, and dont play with roms during work days lol, not to be mean but really, why risk your job and lively hood over some unsaved stuff?
I did actually have a back up on my S6, which I dropped and broke a mere hour before this. So it's not at all an oversight. There were backups in place. And it won't boot at all or I'd had been able to get adb Atleast. ADB won't see the v20 and I tried to flash recovery using fastboot flash recovery recovery.img command. It says unknown.
How can one going about flashing such a boot.img in the H918? Where can one find such things? I assume you mean a kernel of some sort, right?
I truly appreciate the reply. Has I said, it's not like I didn't have backups. I did. It really is an issue of bad luck. : (
i tried this it worked https://forum.xda-developers.com/v20/help/lg-v20-access-to-fastboot-t3557328
Have you tried power on and volume down to go through the factory reset screens.
A bunch of us had this problem and it was because an update downloaded on it's own and the bootloader snoops it out and forces recovery to boot.
Just do the volume down + power button - as soon as you see the lg logo release power only then immediately re-press power and continue holding power and volume down until the factory reset screen pops up. Select yes and yes, (don't worry - if you have twrp recovery it can't reset). It will boot you into TWRP and I'm pretty sure it will delete the update files in fota folder.
In TWRP select reboot - system and it should boot normally like nothing happened.
So, I have a Asus ZenFone 3 Max WW-firmware, android 7. A few months ago the motherboard broke down, without any apparent reason, so i managed to pull a backup to my sdcard from stock recovery mode. Sent the phone to repair, tried to restore backup, didn't work (successful decryption, corrupted data).
Now, I rooted my phone, with the Magisk method, installed the patched boot in the bootloader, restored the backup. I ran the system check from the default recovery, which told me that some system files are corrupted or missing. So i supposed that the data (pictures) i want to retrieve are there, and then installed the twrp in the bootloader (ADB won't let me install it in the recovery partition, which is locked and not unlockable).
I already tried adb commands, phone is not recognized in adb, i can run the sideload mode, but it returns "error:closed", when i boot into fastboot i can only put another bootloader. Device is recognized in fastboot and sideload modes.
I have no idea of the decryption password, probably i had a fingerprint unlock at the moment, for sure no "regular password".
Any suggestion on how to recover these pics? Maybe also unpack the .backup files from pc
Thanks in advance!
Hello,
I have a Asus Zenfone Selfie stuck in bootloop. It is full stock without root, usb debugging or unlocked bootloader. The phone just shutdown without warning and is stuck in bootloop.
I want to recover data like contacts saved in system and pictures so I cannot just wipe everything to get the phone working. I tried various methods without success.
What I thought : I need to unlock my bootloader to load (or flash) a TWRP for backup or root the phone ; but the phone is in bootloop and I cannot install the official Asus application to unlock the bootloader.
=> Is there any way to unlock the bootloader without the application ? (I found methods that required root :
Code:
adb shell ; su ...
but I have no root on the phone )
I also tried to get root without unlocking the bootloader (1clickroot, quickroot ...), but all failed (no error in terminal but can't flash TWRP).
=> Is there a way to get root without unlocked bootloader ?
I also have another zenphone selfie with root and lineage if any hack would need one copy.
Thanks

Edit : I gave up and wipe the userdata partition, but I'm still interested if anyone has a hack.
Is it possible to rescue data from an encrypted phone (copperheados installed) that won't boot?
I don't really know why it stopped booting other than the OS was complaining about 'low on space' on the SD card. Apps then started crashing and I simply tried a reboot. Which left me in a position with locked bootloader. Phone boots to encryption unlock which succeeds after providing the pin code but is then stuck on the copperheados boot-logo.
Can I recover my data (mainly photos) in any way?
I can get to copperheados recovery and the only available option is "adb sideload". But where can I find a copperheados image nowadays??? I'm guessing that is my only option?
Adb can't find the phone while on the pin code screen or in the bootloader screen. Only fastboot and I'm guessing unlocking it will make file recovery impossible??
I seem to manage to get into "sideload" in copperheados recovery. Maybe if there was an ota image I could download and sideload? None seem available though
Ofcourse I don't know what is actually stopping my device from booting.
