Flashing S20+ Ultra - Samsung Galaxy S20 / S20+ / S20 Ultra Questions &

Can anyone post the steps for flashing firmware without doing a factory reset?
My S20+ Ultra has some sort of SW error and will not unlock the screen even entering the right password.
There is data pics/vids on this phone I don't want to lose and no other way to recover, I am hoping there is a way to recover the phone without deleting the date.

I have a copy of the firmware by using Bifrost, I would like to side load through an SD card, the resultant file after Bifrost ran is xxxxx.zip.enc4 do I rename this to update.zip copy to SD and boot into recovery mode and select Apply update from SD card?

G1 boot loop

Alright, I've been following a guide to root my G1 (won't let me post the link because I'm a new user...), and I didn't back up the files that were on the SD card. the guide says to format the microSD card to FAT-32, which it already was, so I decided to skip that step and I left the files that were already there on the card. next I downloaded the dreaimg.nbh file and immediately copied it to the microSD card. what I didn't realize was that the file wasn't finished downloading when I copied it to the microSD card, so that's probably what is ****ing up my phone right now. I tried to flash the image and that obviously failed, so I did what the guide told me to and re-formatted the card and re-downloaded the dreaimg.nbh file (completely this time).
Now whenever I try to flash the image from the microSD card the phone says it cannot find an image and goes back to the home screen. I can't boot up the phone normally now, and I've tried restoring the phone to factory settings with no luck. how do I fix this and root the phone properly? thanks in advance.
to be more specific, it's stuck on the bootloader screen
can nobody help...?

Stuck in emergency menu

Hi!
I was trying to install Kezra rom.
So i searched and read that i need to install Clockwork Recovery and i followed the tutorial but i made a mistake and when i should put the recovey file in internal memory i put it in external SD card.
So, after that i rebooted in recovery mode, wiped/cached out, and then when i was to access the sd card through the "external_sd" folder it doesn't show anything.
So, right now i just can access internal memory, and if i reboot normally it boots to the emergency screen.
I can't install MTP driver, it fails install.
Is there a way to access the internal memory through USB or any other way? To be able to transfer the file and then proceed with instalation?
Thanks in advance,
piro.lito
Can you connect it to your computer?

[Q] no OS and ROM zip files corrupted on external SD!

While on the below thread .. I eventually ended up making my TWRP to format my data, system, cache, as well as internal storage!
http://forum.xda-developers.com/showpost.php?p=46522379&postcount=364
Now it is all gone. successfully.
Note, when i formatted the internal storage - it did ask me to restart to update the partition tables. I did that. I warned me that there is no OS. I went ahead and restarted in recovery. I could browse using TWRP->advanced->file manager and see the zips on external sd card.
I had gapps and rom zip files copied on external SD card. When I try to flash those in TWRP, it throws an error - E: unable to open zip file!
Now I can not flash any of those! there is no OS also on the phone! I suspect that the external SD card is corrupt! I have good zip files on my computer (it has no working sd card reader).
Is there any way, i can transfer these zip files from my computer to phone's internal storage from where i can flash them?
please help!

There's no way to effectively access internal SD without having been mounted first.
But there are two ways you can do this.
1. Take the MicroSD Card and insert into the PC via Card Readers.Then copy the zip files there. Properly eject the card from PC then insert it into the phone. Now TWRP will recognize the files and flash them. If it still does not then its a bad download so download again. Also while there, get the MD5 values as well for your zip files. This allows the recovery to validate the files. If you still have errors then roll back TWRP to version 2.5.0.0
2. Put phone in download mode. Use Odin on PC to flash one of the rooted stock roms. After that, proceed to re-download on phone and try again.
P.S. - I typically never let Recovery to format my external card. Then the file system issues start popping up.
EDIT - I noticed from your other post that your PC does not have a working SD Card Slot. In that case, you could put the card in another phone and then copy the files to this sd card and then use that way.

How do I flash CM or MIUI ROM using odin? I am trying to search the forums but unable to find anything! odin needs a tar file and all these roms come with zip file! What do I do?
You can't unless the dev specifically made an Odin flashable version, which they never do. Flash the stock root66 firmware with odin.
You can't access the internal storage simply because it's not there anymore. When you chose to format data, it completely wiped out the /data partition. Your internal sd is really located at /data/media, but until you can reboot, this won't be recreated.
I doubt the external sd is corrupt or you would've seen issues before your wiping frenzy. But you can use adb while in recovery to connect the phone to your computer. Search for adb sdk install guide, or similar.
Best option now is to try Odin flashing the root66 firmware.
Oh, and you probably know by now, but never format system! This should only be a last resort type thing imo. Never understood why people recommend it for things like prepping for a Rom flash. The Rom will format system during install anyway.

I used this
http://apcmag.com/how-to-unroot-your-galaxy-s3-and-flash-it-back-to-stock-rom.htm
and got the stock rom back. appeared like that was the only way to get back to running system. Now it's alright.
to my surprise, following problems disappeared.
1. The SD card no more automatically ejects!
2. battery lasts longer!
3. no random reboots at all!
never thought .. i would feel good getting back to stock rom !
Isn't that exactly what we were telling you to do in the first place though? Use odin to flash stock/root66 firmware? I think you just took the long way is all. I also have all that firmware hosted so people could download it much faster than by using sammobile or samsung-updates hotfile downloads.
Either way though, glad you got it running again!
Just posting so others know if they come across this in the future.

yes guru! you said it.
I tried adb route too ... but for some reason it never detected my device. I tried removing, installing drivers, getting sdk and all. then tried the odin route.
Now will stay with this rom for some days ... before I get back to MIUI ... want to see it working ... for some reason it was continuously making my phone reboot! now that it is a clean slate, i hope this time, it will work!
fingers crossed!
If you want to try adb again for anything in the future, there's a different driver pkg that would probably help there. Adb universal drivers. Theyre in my driver repo with the rest if you ever need them.

problem flashing "encrypted" ROM from SD card

I'm trying to flash stock WW Nougat ROM onto my UK Three P2 from an unencrypted SD card but it says file is encrypted and fails. I've renamed file update.zip and tried it on a few cards all with the same problem.
Can anyone help?

Maybe download it again. Download it on a pc and format card prior to copying it to card and put card in phone while off etc as phone encrypts it I think soon as inserted. Just did my wife's and had to re format the card that was in my p2 as above or it failed.
i had the same issue with the three uk edition its because the phone keeps the file encrypted when downloading directly to device you need to download it on a laptop or pc (ect) and then move it over to the device through a sd card (take it out the phone) it will work then if you change the name of the rom zip file to UPDATE.zip (must be capital's) it took me 2 weeks to figure it out the phone has same kind of block on it being oem unlocked on a few devices (comes up with some weird things in bootloader mode)
Update don't need to be capitals.

0 internal memory after removing sd card

Hi!
So i formated my sd card as internal memory, and few days later just remove it from slot and format when in other phone. Then i placed it back in my phone.
The problem is, now in file explorer it seems i have 0B/1B memory free, I can't make screenshots, make photos or download files, but i can download apps from google play.
Any ideas how to fix it? I didn't try factory reset yet, but it is last option for because phone is rooted, and i have apps that aren't backed up at google.
Device:
Xiaomi mi a2 lite
magisk rooted
no twrp

As far as I can tell , when you formatted as internal storage , you have transferred the data from the main storage to SD card. Before you remove any SD card , transfer the data from the card to internal storage , then format the SD card as external from the phone. You didn't do that , so you messed up the partitions right now. For me the Factory reset is not the last , but the only option. Never take out the SD card if it's not formatted as external.
The last thing that you can try before factory reset is to try to flash the stock firmware via MiFlash tool, but you need to choose the option "save user data " from the bottom right corner of the tool, the hit the flash button. It might work. If you don't wanna use MiFlash, just decompress the stock firmware and execute this . bat file : flash_all_except_storag.bat
You can try to boot in TWRP and backup the data partition. But I'm not sure that will help, but these are the options that I can think of.
