[Q] Need help with a soft brick

Alright, so i have a Galaxy s3 (sgh-i747) and i rooted it with philz bootloader
So i was going to install a custom rom, so i had to wipe.
I downloaded the rom, and wiped.
But then i realized i actually never put the ****ing rom on the phone and now my phone has no rom loaded.
I can still boot into download/recovery
I really need help with this, what are my option?
So my phone is not rooted any more i guess because the recovery/bootloader is the default one

I still really need help with this

Do you remember what (stock) firmware or Android version you were on before the attempted installation? Your best option now would be a return to stock. If you were on anything earlier than 4.3 (e.g. 4.1.2 or 4.1.1) you could try using Odin to flash 4.1.1 since you can get into download mode. To do this take the following steps ..
1. Download the required files via the following link <http://fortedge.com/downgrade.html>and extract the Odin flashable file
2. Install Odin
3. Boot into download mode and flash via Odin
OR you could find the correct stock image via the following discussion thread and flash via Odin. This would be a complete stock file that will flash all partitions including bootloader, modem, kernel and system.

If you were on Android 4.3, then you cannot use the above method or flash via Odin and any attempt to do this will create more bother for you. In this case, you would need to flash custom recovery via Odin and restore the stock recovery image via custom recovery. Please download the stock recovery file via the following the thread ...

If you need any further detailed steps on how to complete this, please do not hesitate to holler.

Download Odin.
http://fortedge.com/downloads/Odin307.zip
Download the Odin flashable custom recovery file via the following link ...
<http://techerrata.com/browse/twrp2/d2att>. You need one of the more recent images ending in *.tar e.g. the one below
<http://techerrata.com/file/twrp2/d2att/openrecovery-twrp-2.6.3.0-d2att.tar>
Install Samsung Kies on your PC if you don't have this already (this will be useful for the drivers)
Install the twrp tar file to an easily remembered location on your PC
Extract the Odin zip to get the executable file (*.exe)
Click on the exe file to run Odin
Now boot your phone into download mode by powering off completely then holding down the Power + Home + Volume Down buttons simultaneously until you see a warning message.
Press the Volume Up button to continue
Connect your phone to the computer with a good quality micro-USB cable
If everything has been done OK, Odin should immediately recognize your phone and you should see a message saying "Added" in Odin. If you don't see this, then you may need to check the drivers are properly installed.
Click on the PDA tab in Odin and navigate to the twrp tar file you earlier downloaded. Select this file and click OK.
You should have the Auto-Reboot and F-Reset Time boxes checked in Odin. Please do not check or uncheck any other boxes!
Click on the Start button at the bottom to start flashing TWRP and wait until you see PASS and a green (or blue) box fully displayed. Your phone will automatically reboot after this although it may not be able to boot since you don't have an OS installed. You may disconnect the cable and close Odin after you see the PASS message. If you see FAIL, then disconnect, remove the phone battery and try again.
If you successfully flash TWRP, then you may proceed to reinstalling your ROM.
1. Download the zip file in the thread below <<http://forum.xda-developers.com/showthread.php?t=2658486>>
2. Save to a recognizable location on your phone's SD card. If you can't install files to your phone via your PC, then you may save to a micro SDHC card using another micro-SDHC compatible device (camera, another phone, card reader/writer etc).
3. Boot into recovery mode
4. Select Install from the TWRP menu and navigate to the zip file you download. Swipe the arrow key to confirm installation and wait for installation to be complete
5. When installation is complete, clear your cache and dalvik and reboot system and you are good to go.
Hope this works for you. If it does, please remember to hit the thanks button and let me know.

You may also try Odin 3 v1.85 if the v 3.07 didn't work. I've been looking for a safe download link for that online but I've not been able to find one. You may try searching for it online.

Here is Odin 1.85

Or you could try putting a room on an SD card. That's why I always check to see if a room is there before flashing

unbrick Nokia 3.2

Hello together,
after many tries to get my nokia 3.2 rooted, i end up now with a black screen.
Only the Qulacomm mode is working.
Get anyone managed to flash the stock firmware with QFIL provided from the rooting thread?
I always end up with "sahara fails".
Every help is welcome!
Thanks!!!!

After many tries I have finally put my phone back to life.
My instructions how to do it will come soon!

please do, i encountered a similar problem.

HowTo Flash STOCK 00WW
1. Trigger nokia 3.2 to edl-mode (https://forum.xda-developers.com/nokia-3-2/how-to/guide-how-to-trigger-nokia-3-2-to-edl-t3962841)
2. Flash the given image from this thread (https://forum.xda-developers.com/nokia-3-2/how-to/rooted-nokia-3-2-t3945206)
- This was the main problem. I never managed it to flash the image with the Windows Programmer QFIL. After more research in Internet, i found finally a Linux application called QDL that work directly without any problems. This application can be found here https://www.96boards.org/documentation/consumer/guides/qdl.md.html .
- Flashing the software ends up into a bootloop. Also i got a message on startup that the bootloader could not be trusted anymore. After a software-update, this message disappears.
3. Flash all the user images again manually with fastboot.
fastboot flash boot boot.img
fastboot flash dtbo dtbo.img
fastboot flash system system.img
fastboot flash vendor vendor.img
flastboot flash vbmeta vbmeta.img
Whyever you have to flash this partitions only to the active partitions without the suffix _a or _b.
Then the bootloop is finished.
The phone boots normally to Android ONE.
The next problem which occurs on my phone is now that it is not able to connect to GSM network. I guess this happens because i deleted all the necessary partitions for the modem (modemst1, modemst2, fsg).
I get it managed to restore the imei, but still no service available.
In original my phone had the software 00EEA. Perhaps they use different drivers. My luck is that i got a cheap damaged phone from ebay with that firmware.
My next step is to modify the code from QDL that it can read the partitions from the damaged phone and save the software to computer.
Then i will flash this software to my phone and look if this software will run on my phone!

Thank you for your reply, it seems that your problem is more complicated than mine.
I have a global variant with 00WW software and i attempt to root the phone. I successfully flash the patched boot.img and had root access. However wi-fi didn't work after that.
Since before flashing the patched boot.img my phone was running on a different firmware from the one that boot.img was extracted from, so i think that was the problem.
I attempted to use QFIL to flash my phone back to 00WW_15 and it failed half way, bricked my phone.

Normally you can use the EDL Mode every time.
My phone only showed black screen and it was always possible to connect in EDL Mode and flash again.
Did you try to flash again? What happens then?

What did you mean by Flash the given image ? Was it flash the firmware package with QFIL ?
My main problem is flashing, it always failed half-way and the error log reported that needed files were missing from the package.

Okay. I used the linux program QDL for flashing.
But i saw, that in the xml file rawprogram0.xml a few files are missing.
The linux programm jump over these files but perhaps QFIL do not.
For example is there a picture.img listed which is not available..
Try to remove them manually from the rawfile and test again.

@update:
Also the files "demoapp.img", "dp_AP_signed.mbn" and "dp_MSA_signed.mbn" are missing.
Remove them from the XML file and try again!

Okay QFIL still failed half-way but i manually flash the user images and my phone boots normally now

Hello,
my nokia 3.2 europe variant wont boot up its stuck in fastboot mode. What can i do to bring it back?
I get this: FAILED (remote: partition table doesn't exist)
P.S. if i do a fastboot reboot it boots back into bootloader

I also had this problems for many many times and don't know what went wrong when this happens.
The only thing that helped was flashing the complete firmware again in EDL-mode.
You can try first to flash only the 5 user-images with fastboot, which i mentioned before in this thread.
I uploaded this files for you, because you don't will find the europe files in internet yet.
Here is the link:
https://transfernow.net/81iti7q21s0s
Good luck!

Hi,
Thank you very much. Is this the complete Firmware? (All Images from Device) Another question: I couldnt Access the recovery System. Did you have the same Problem when your Nokia didnt boot up and was stuck in Bootloader? So is this normal that the recovery is unaccessible?

Yes, that also happens sometimes with my phone.
No, that are not all firmware files, which you need to do a full EDL-Flash.
But with this files you can first try a fastboot flash!
If it does not work, you can take all the other files from the Global-Stock-Firmware, given in the thread https://forum.xda-developers.com/nokia-3-2/how-to/rooted-nokia-3-2-t3945206.
Delete the 5 files with the same names, flash the Global-Stock-Firmware in EDL-Mode, with QFIL or QDL, (without the 5 files) and in the following flash the 5 europe-image files with fastboot.

Thanks, ive sent it in and got Friday a 00WW Variant of the device back. I will upload those User images for 00EEA to my Google drive so that anyone who needs those files can download them

Download the stock recovery from this guide extract it and flash it while your phone is on fastboot.
Before you flash stock ROM, you need to have the rom zip file either in phone storage or the sd card. You can use adb push commands to transfer the rom file to phone storage folder. ROM OTA can be downloaded from the realme official website.
Once you have the file, just select install from phone storage / install from sd card and it will flash the stock rom.
This is how I recovered my phone when it was bricked.

Softbricked Mi10t Lite (gauguin)

Hello guys,
I have rooted 2 days ago my phone with TWRP and Magisk; everything worked fine until I tried to change somethin in /system/ folder. It always said I dont have write rights. So I decided to go back to stock rom. I have downloaded the stock rom for my phone (gauguin, Global 12.0.8.0 , Android 10.) Now I have the following problem. My device is soft bricked.
So i decided to google and try to flash another Rom for my phone. I found one here.

For the love of god, I just spent 3 hours to install fastboot ROM and did not succeed. No idea what went wrong, but at the end I finally restored my device..
1. download recovery ROM and transfer it to internal SD
2. download fastboot ROM, unpack it
3. modify flash_all_except_storage.bat and delete lines with CRCLIST and SPARCECRCLIST
4. run the script
5. phone will keep rebooting on MI logo
6. boot to TWRP "fastboot boot twrp.img"
7. install recovery ROM from TWRP
8. (install Magisk), reboot phone to system
For some reason fastboot flashing doesn't install /odm partition correctly. I have the latest drivers, android tools, tried 2 PCs, 2 different USB cables, different USB ports, using Mi Flash, nothing helped. The only solution was to flash recovery rom from TWRP. Fortunately no data has been lost.

Can you boot into fastboot? You said it's soft bricked so I imagine you can. Reply and I'll get back to you, I soft bricked mine and fixed it fine.

Hey guys, I was finally able to flash the Rom.
I used to flash a Rom with Xiaomi Flash, accidentaly it was a wrong rom, which I saw later on.
So I installed TWRP recovery with fastboot commands and downloaded the right rom. I used to download the EEA Rom instead of Global Rom. So I transfered the EU Rom to micro SD Card and flashed it with TWRP.
Everything is working now, except the access to /system folder, after I rooted with magisk 20.4. Even with the newest Version it does not work.
So I tried in the terminal the following command while I was in /system folder: mount -o rw,remount/ But this does also not work. How can I get acess to it?
Sorry for my english again

Think you storage is corrupted what I did was download the ROM for my phone open the tar ROM to you see a file says images flash all and other stuff play rom folder in mi flash tool folders and open CMD use flash all in ROM folder

Make sure your phone is in fastboot before you use the flash all file it will return your phone to stock ROM

Hi,
I have the same problem.
Any chance you could share the method of how you managed to connect otg to transfer the ozip file? I also only have access to stock recovery and the fastboot mode.
I have the stock rom in zip file version which i am absolutely certain works because i have used it before but i can't install a custom recovery no matter what i try.
If possible could you also share the ozip file and the odp file?
Thank You!
