Brick? Or Is this a Bootloop? Expertise needed. Video provided. H918 - LG V20 Questions & Answers

So I'm manning up and saying that I did indeed screw up this phone, but to what extent is unknown to me.
Didn't make any backups or anything. Can this phone be saved?
I can get to the fastboot screen and I can also get to TWRP... but that's it. Otherwise it stays at the T-Mobile white screen.

Lets cover the basic questions. Have you wiped cache and dalvik cache? have you wiped data? have you factory reset? have you flashed a rom (as in .zip file compatible with twrp)? did you flash a rom not meant for your phone?
Truth to be told. this does not look like bootloop nor brick. if it were brick, i dont think it would even pass from the first screen. Maybe some of your system files got corrupt. Reflashing the stock rom should solve the issue.

I've wiped everything TWRP lets me wipe (Dalvik/ART Cache, System,Data, Internal Storage, Cache, Micro SD Card, USB OTG). When I do the factory reset it tells me "No OS Installed" but I'm sure I picked the stock one.
I'm thinking you're right about the files getting corrupt (or maybe I accidentally deleted something important ). I actually wouldn't mind reflashing the stock rom, but I think the one I have is corrupt or I'm flashing it wrong, orrr I'm following an outdated guide.

Copy a rom for your version. H918. Or download Alpha rom for h918 then flash it through recovery. But don't forget to format only, "format data", internal storage then flash the rom. You should be good to go. I am here to help

Hey, thanks, flashed (Discontinued) Alpha Omega Rom zip through TWRP and I got the phone working again. However, I can't download the T-Mobile security update... not sure if I even need it though. Everything else seems to be in working order.

No u can't and u shouldn't if not it might cause an issue. Alpha rom is a stock rooted and tweaked rom. No need to update. Only the dev can do that. Just keep using it that way.

hmm i would probably try restoring sans odin...should fix whatever partition issues your having
I had to restore from KIES...
Wouldnt boot again.
Go in stock recovery and
Format data / factory RESET the thing...
WTH I almost tought i lost it for a sec !!
Never format data. What you should have done is odin back to stock, then factory reset through stock recovery. Kies is hit or miss when it comes to recognizing the phone in that state. You got lucky. There are a few topics on how to fix the problem you had.

I format /data every time I flash a new ROM and I experience fewer bugs because of it.
I just back up all my important files (data folder) to external SD and then restore after I install the new ROM. Works great for me. :good:

I'm mostly on TWRP but I do it in CWM also.
At most, your issue (whatever it was) was due to user-error or a random system glitch.
At worst, you have to ODIN back to stock which only takes about ten minutes to do, five minutes to re-root and install TWRP and then you're good to go again.
Don't know if any further research has been done on this subject, but it's the only thread that came back with TWRP+format.
This same thing happened to me last week, I *think* it was my first internal format on my i337, was able to boot then fail.
Odin back to stock fixed issues.
Any thought why this happens? Any suggestions for best clean format approach besides an Odin? Flash CWM/Philz for the format then back to TWRP if desired?
I'm currently stuck in the same situation. Used TWRP to format /data to try and clean up the internal sdcard and now I'm bricked. Flashed 3 diff recoveries and about a billion roms, nothing works. Downloading a fresh odin flashable stock rom as we speak.
edit: so flashing stock rom via ODIN wasnt quite enough. I then had to enter stock recovery and do a factory reset. I noticed any time I tried to format /data the system would crash and reboot. The stock recovery was able to properly format data and now I'm back on a custom recovery/rom again.

[Q] Galaxy S4 (....process.media-phone has stopped) Unroot failure! Please Help Devs!

Greetings all,
I have the i9500 S4,
I was running Hassan Rom and everything was fine, yesterday i've tried to boot the OzcanRom, and kept getting the (process.media. and process.phone not working)
The phone was not working, and after multiple tries of rebooting the said rom, i decided ill go unroot it and install the stock official rom (as i need my mobile for work etc...)
What i did is wipe the dalvikcashe and the system files (which i think was wrong) and tried to flash the stock rom via Odin the old simple way.
Everything went fine, when my mobile turned on again, i kept getting the same messages:
(the proccess android.process.media... & the proccess android.process.acore... & the proccess android.process.phone... Unfortunately email has stopped...& the new message Unified Deamon (EUR) has stopped.
The mobile is useless, can't access anything, can't connect to USB media so i can backup the files, can't connect to WIFI as it restarts...
Please help me guys as soon as possible i really need my mobile for my work...
(Preferably without a full wipe, or if necessary offer a backup way for my gallery)
Should i try installing a different stock rom? as i chose one from SamMobile that was the closest to my region...
Perform a factory reset. You can do that from the recovery or from within android. Make sure to backup the files on your internal storage.

Thank you for the reply.
I can do that, but i can't backup the files as nothing on the phone is working, pressing the gallery button for example, leads to the (process.media not working) message.
Any other solutions? i don't understand, isn't flashing a stock rom supposed to solve all these issues? should i try flashing another version of the Roms (different region perhaps)?
It does solve it, but you need to factory reset.
What I would do:
- Flash a custom recovery.
- Do the wipe option prepare for new rom.
- Flash stock/custom rom.
That way your internal storage won't be wiped.

Great, Got me relieved when you said internal storage won't be wiped.
Thank you for the reply, i don't want to be a pain in the ***, but could you please explain a few things,
What i'm gonna do is, flash a custom recovery (please recommend one that has the wipe for new rom)
Then, Do the wipe option, which wipe option, the recovery i had had only 1 wipe option, how do i know its not the one that's gonna wipe my data)
Finally, ill flash the rom. (Do i need to root my device again then? to flash a custom rom, if yes, im just gonna go with stock rom and let my mobile work for a few days where i need it then root and install a custom rom again)
I really appreciate your help, and your prompt answers.

- You can use Philz recovery
- You know the wipe option when you see it. The one that say prepare for new rom. No custom rom will wipe your internal storage. That option is somewhere hidden.
- You don't need to root, just flash.
ps you will lose all your apps. It will not wipe your internal storage.

Encryption that can't be formated

Hi,
I set up TWRP 2.8.7.0 and cm-13.0-20160129 on my Samsung Galaxy S4 LTE-A (GT-I9506), and run into an odd problem where it would work after install, but would not work after a reboot (booting screen would just roll for ever). Installing CM again, would work, and than the problem would still be there. Mindlessly I decided to play a little anyway and set up encryption. The phone ended up rebooting, and not loading, so I'm here without a password (default_password doesent work) and with an encrypted /data that TWRP cant wipe or format
Unable to mount storage.
Unable to decrypt data
Unable to wipe '/data' -- unknown file system 'auto'
Unable to format to remove encryption

I've attempted to use ADB to format it, but it seems parted isnt installed. With that phone being a less popular variant I'm kind of afraid to just flash whatever there, but I guess I need a recovery with a least parted, or possibly one that would be able to format the drive itself. Any pointers?
Have you tried flashing a stock ROM via Odin? Is this your phone: http://www.sammobile.com/firmwares/database/GT-I9506/ ?
not yet; I don't have windows, and didn't see any point in changing the soft used for flashing, will try but cant download the polish rom at the moment o0 (ends up with a dead link or a server down?)
I know of no other way to flash a stock ROM from sammobile.com other than Odin.
Did you create a free account on sammobile.com to enable the regular download?

You can also flash it with Heimdall. It's the open source variant of Odin.
aaaand I'm back, managed to download, got some windows, flashed to stock using odin, and it's still encrypted. is running 'repartition' from odin safe? I've noticed some warnings against it but without any explanations.
edit; running the same operation with repartition failed. this bloody encryption might be able to survive nuclear war.
After flashing back to stock via Odin, did you perform a factory wipe before booting the rom for the first time?
I assume you have a pit file for the phone since you repartitioned?

never managed to do that. I wonder what advantage does the wipe from factory ROM have over custom recoveries... anyways thanks to all who helped, the issue is solved. also it seems that the problems with non-rebooting CM were my mistake of not wiping the cache/dalvik after install
I find that a wipe using a custom recovery is not always as through as a stock recovery. Can't say how or why, it's just based on my experience with Samsung and Nexus phones.

I think the difference is that a custom recovery only wipes /data partition so that the internal sdcard will not be wiped. The stock recovery formats /data partition. When you want to lose encryption you need to format /data partition.
You can also format the /data partition with a custom recovery, but that option is hidden for good reason. Because it will also format your internal sdcard and that's not something we want to do when changing roms.

Booting issue -

I used Flashfire to flash a radio.img without checking flash bootloader.
I can get into the bootloader and twrp.
When wiping the device and flashing another rom or restoring a backup my 6p does not get passed the custom rom splash screen.
I was thinking of trying to fastboot flash system/data/cache of the March update and see if it boots.
I know I messed up. don't even know if it was because I didn't check the bootloader option in Flashfire. Just my guess because everything was working fine beforehand.
Any help or ideas would be welcome.

Hey... You said you wiped your device? What did you wipe in TWRP?
Try to install a ROM from TWRP. Once it's over go in wipe and do a factory reset. Reboot. It should likely fix your issue.
Good luck...

Hey thanks for the reply.
Yeah, I wiped data, system, cache. Just the standard - I still have internal storage intact.
Its just strange, I've used Flashfire before but not for flashing a radio and it worked out fine.
I am on 3.79 and used Flashfire to flash 3.78. Went to the bootloader just to check and it still shows 3.79. Just my fault . I didn't check flash bootloader in the Flashfire settings. Atleast that's what I am guessing. Things were just fine before

Well, if nothing work, maybe backup your internal storage and flash a factory image... Then in recovery do a factory reset afterward. Who knows. Going back to stock shouldn't hurt anyway.
Good luck...
@dirtyreturn
I've used FF to flash only radio files to the modem partition many times without issue. You untick all but modem, and you untick inject SU and preserve recovery. Not sure what went wrong for you. As mentioned , you should be able to manually flash stock and if you're careful, you'll still have your data. All your settings will be reset, but the userdata will be there. You can even use flash-all.bat, but open it in a text editor and remove the "-w" flag so it will not wipe your userdata. The Google page where you get the full factory image will have instructions.

Thanks. It was obviously my fault somehow.
I do remember there being only one option to tick.
Using fastboot back to stock did the trick and made me realize maybe I should hold off on using Flashfire for a bit.

Didn't read the instructions very carefully, now did you? The very FIRST thing you need to do when booting to TWRP is to FORMAT THE DATA PARTITION. Not wipe, but FORMAT. The data partition is encrypted and TWRP can't read it. That is why everything looks weird. Also, that is why you need to backup any pictures, downloads or anyting else you want to save because formating the partition will erase EVERYTHING and not just system stuff that wiping deletes.

My post pointed out that formatting would erase everything and that you should backup prior to doing it. And there are several other methods of backing up data and apps besides TWRP. Yes, it leaves the data partition blank, but flashing a ROM and gapps will put the directories back. Of course, they will still be empty. If you used a Google Account, then that should have at least backed up your apps and some settings. When you setup a new ROM, it should let you restore them.
BTW, yes it was the first time it happened for most of us. Samsung keeps trying to improve "security" and adding encryption, by default, to the data partition is in all of their new tablets and phones.

You can't backup a stock ROM with TWRP because it can't handle the encryption. But you can use TWRP to root a stock ROM. In that case you just ignore the wierd internal data and put what you want to flash only on the external SD. IOW, if your reason for flashing TWRP is to use its backup function on a stock, don't bother, it won't work. But if your intent is to ROOT the stock ROM, then go ahead, but DON'T format data. Just put the files needed to root on the external SD and flash from there. You format the data partition in order to flash a custom ROM.
