Help, can I Reinstall an OS on a bricked Z3?

Hello there, rooted my Device but ended up in Bootloader,
through Panicing i went Bootmenu and wiped my data with Format Data,
did no backup since i havent had personal Data on it anyways.
Now i just don't know how to install a ROM or OS and would need some help,
i have access to my PC via USB and TWRP is also accessible.
Would need some help if there is any.

It seemed a lot worse in title. Just use xperifirm to download firmware files and make a ftf in flashtool, then use prfcreator to make a prerooted zip file with root and twrp recovery. copy that zip to hpone by booting into twrp and connect your phone with usb, it will be detected. it will be helpful if you have sdcard in there as you can wipe all 5 internal partitions although that's not necessary
EDIT: I just reread and you said you only wiped data, before all this try wiping both caches in twrp just use wipe, and see if it boots.

I did format it(+factory Reset), so you say, i didn't delete everything, i just ended up in bootloop? I though it deletes OS too. (already tried to get rid of the Standart-Bootloop) When i connect it with USB it only shows the TWRP Folder to me.
Thank you so far

Download kitkat 4.4.4 or lollipop 5.0.2 for your region via xperifirm and use flashtool to flash it.

If you'd like to restore it to factory conditions,
1) . Ensure Sony PC Companion is open (URL="http://forum.xda-developers.com/showpost.php?p=63381257&postcount=98"]CLICK ME TO DOWNLOAD SONY PC COMPANION[/URL])
How to put my device in flashmode:
1). Plug the USB into your PC
2). Plug the micro USB into your phone and at the same time hold the Volume Down Button
3). If completed correctly i believe the device Notification LED lights blue for a brief second or longer

4). Once you've put the device in flashmode and Sony PC Companion is open it should detect a device in flashmode and it'll prompt you to install the latest version available,
I hope this helped!

we all started from that place only bro, Now install Nut Recoveries, SuperSU, Xposed and sound mods, hell yeah your good to go

I don't know what my buddy did...

Wow this thing sucks! I'm really appreciating my Samsung with Odin right now! So, I have years of experience rooting and flashing Samsung phones with minimal adb experience. My buddy from work asks me if I can try to fix his shield tab that he F'd up trying to flash a rom on. Come to find out he never unlocked the bootloader or flashed a recovery or rooted the dang thing, just tried to flash the rom over stock like a numbskull. We thought it was dead forever because the only thing that would mount or connect in adb was the side load through the stock recovery. So, I finally got it to connect to fastboot (don't ask me how, I don't know), unlocked the bootloader, and flashed twrp. Now it won't flash supersu in adb sideload, so I put it on an SD card (which now magically mounts and works now) and flashed the zip in recovery but it says at the very end of the process while trying to update the partitions that it can't mount the data and system partitions so I'm not sure if I'm actually getting root or not and if so if it's permanent even though it says "success" at the top after flashing. I have no way to tell. I think this is because they have been accidentally wiped. Do you think it is safe to try to flash a rom in recovery from external sd card? And if so, which one? I have no idea which version bootloader, kernel, or os is, or was, on this device, I'm not familiar with any of the roms for it, and I'm not sure what prerequisites there may be for some of them....
Thanks for the help!

I had the same Problem with the partitions you discribed, have tried wipe them, change the file format and change it back?
I flashed a lot of Roms from the external SD Card and it worked every time.
I think you should go with Bliss Rom. ( Just try Lollipop and Marshmallow)

I can't wipe them because they won't mount. It's as if the partitions were erased completely. Not like the partitions were wiped, but like they don't exist at all anymore...
What do you mean by changing the file format? Format of what?

TWRP, wipe ,Advanced wipe
If that doesn't work just try installing a rom, boot it
If that doesn't work try this

Tried all recovery options and tried flashing bliss 6.2 with no luck. It says that it flashes successfully but also shows some errors about not being able to mount the system and data partitions. Then when I try to reboot it gets stuck at the nvidia logo (this is the closest that I've gotten to booting a rom). I can provide pictures if you want. I'm going to try the steps that you linked to as soon as the files download.

Phone got stuck

i was trying to root my phone and install twrp in it. Then twrp came on screen then i wiped the data and copied one rom in internal storage and tried to flash it but it got into error. I tried again but result is same. so i tried to reboot phone into recovery so that twrp must reload again but it went to default oneplus recovery which it must not go(correct me if i am wrong). now as i know that no os is installed in my phone and i am in recovery so then i tried to soft unbrick my phone when i connect my phone to computer but device is not showing in device manager which it should(correct me if i am wrong). Now i don't knw what to do. Please help
Thanks in advance.

Have you enable mtp ?
Twrp recovery is best recovery use it
Download twrp.img from official site
Flash it through your present recovery.
After it format everything data, internal storage,dalvik, cache.
Reboot twrp
Install any custom ROM.
Enjoy

You got a option in recovery to enable mtp
If you select keep read only partition them you can only read you can't format or write anything.
When TWRP starts it shows this option Keep read only partition. Many of guys check this and swipe.so they have problems to flash and wipe anything.
Connect a mmc using card reader with PC.
Copy custom ROM
Select install
Select mmc
Select file
Wait for process done
Wipe dalvik,cache
Reboot phone.
Done

In need of help! TWRP!

first some back story:
it's been a long time since i did a lot of rooting so i lost a lot of knowledge.
I got the phone close to release in the EU.
There was only BETA stage twrp at the time.
So i flashed this unstable twrp and rooted with magisk.
And i run stock Oxy Rom.
But the main problem is, whenever i boot into recovery, twrp ask me for a password. (i have none) so i press continue.
And it then ask for unmodified system partition. (not sure what to select here)
But when i swipe to allow modification, i can't find the root of the phone? i cannot find the download folder where i flash updates or other modified apk's.
It's all just numbers and random letter. i have no idea on how to proceed or how to update twrp safely without falling into boot loop and other problems.
Some help would be appriciated. Thank you.

and which of my problems does this solve?

First of all flash official TWRP now. Makes no sense to use the unofficial version because its not stable.
Enter PW -> decrypt data for TWRP
No PW -> hieroglyphs

I successfully used official twrp, version 3.2.2 and then did a "format data" and then used fastboot again to install the full rom.

U have corrupted u r data partation u have to factory reset along with wiping internal storage and then transfer u r rom File through MTP in sd card of phone and then flash rom.
Or u can flash fastboot flashable rom via fastboot mode.
Then install your official twrp via fastboot mide after installing rom.
Now twrp will detect all data from sd card

Can Anyone help me, please? I have somehow the same problem. The phone literally itself without doing anything started doing a download(odin) mode loop. So I deleted data, dalvik, cache, system partitions without internal storage since it has very very important files for me and a lot of projects for the university!!! and before and after the folders in internal storage in twrp shows as random numbers and letters. I don't know why since when the phone was working normally I was protecting it by fingerprint and a password. And when I installed a stock ROM after it without wiping the internal storage. The storage is showing in negative. If anyone can help me this would be super appreciated and helpful. Thank you!

If it is already showing folders with random file names in the internal storage it means it needs to format data (to remove file encryption) which deletes all files in the internal storage.
Don't wipe system because it removes your OS.
Always secure backup before messing your device.

You may try this boot.img just rename to boot.img only.

Sorry I thought you are also literally same issues with OP but then it's not. Are you able to reboot to twrp? And what is the whole story of you device? I mean if you are rooted, what ROM you came from and all that you did before the issues occur. And did you tried to switch slot? Since you wiped everything with system included then you have no OS installed. Did you tried to flash OS via OTG? Or flash via fastboot.

I flashed another os without deleting the internal storage but the storage is now showing in negative values. Story is The phone literally itself without doing anything started doing a download(odin) mode loop. So I deleted data, dalvik, cache, system partitions without internal storage since it has very very important files for me and a lot of projects for the university!!! and before and after the folders in internal storage in twrp shows as random numbers and letters. I don't know why since when the phone was working normally I was protecting it by fingerprint and a password. And when I installed a stock ROM after it without wiping the internal storage. The storage is showing in negative and yes I can still boot into twrp

First of all, rom and recovery are not from me... I just want to make a full guide to help you
So let's go !!!!!
1 step: unlock bootloader

Be sure to have adb and fastboot tools on your computer ... If not take a look at here
https://forum.xda-developers.com/showthread.php?t=2317790

Open a cmd here.
Enable usb debugging on your device
Reboot your phone on bootloader (hold volume down + power), connect it to PC and tape:
fastboot devices
fastboot flash recovery TWRP_umi.img
Then tape fastboot reboot while holding volume up button on your devices to reboot in recovery
3 step:
At the first launch of Twrp You have to choose SWIPE TO ALLOW MODIFICATION

Does Xiaomi EU Rom run either on encrypted and unencrypted storage?

I cant get this to work, ive been trying everything for hours. I am sure i am missing something stupid but if anyone has any new ideas please let me know. I unlocked my device today, flashed twrp via fastboot, rebooted to recovery, formatted data then went on to install xiaomi eu rom. Ever since trying this, i am constantly booting into recovery or hitting a boot loop. i have formatted data more times than i care to think of ha ha. ive tried flashing the latest fastboot rom via mi unlock tool to do a fresh start but keep getting ''flash crclist error". Ive also tried flashing miui stock via twrp and it also, doesn't boot. ive tried many combinations in between. My next option is to try the fastboot global rom (though i believe i have a chinese device), i am waiting for it to download. If anyone knows what i am doing wrong i will be eternally grateful if you can tell me what it is. I'm so frustrated, been flashing roms for years, never had anything take as long as this :crying:

I have followed the tutorials to perfection like 2-3 times and I still face the same issue
I always go back to TWRP after trying to boot into system.
I have tried 2 different recovery files
The experimental one asks for a password. and the other one works but keeps going back to recovery after flashing.
MIUI 11 rom
MIUI 12 rom
No matter what I do It keeps going back to recovery.
It's my only device so I truly need help.
I have tried re installing everything already.
At this point I just want to install stock rom and keep using it without flashing anything please help.
PHONE FINALLY REBOOTING INTO SYSTEM. I myself don't know what i did!!!

Bootloop (stuck on 5G logo) after flashing Xiaomi.eu ROM
Dear fellow XDA-dev community members,
Xiaomi Mi 10 (umi), coming from original stock ROM, MIUI 11 GLOBAL version V11.0.2.0.QJBMIXM.
Bootloader unlocked official way via MiFlash Unlock 4.5.514.47.
Custom recovery TWRP 3.4.1b-0313 installed via XiaoMiTool V2.
Tested root by installing Magisk 20.3 via TWRP, no problem, then updating to Magisk 20.4 with the Magisk Manager 7.5.1.
The problems started when I tried to install Xiaomi.eu Custom ROM : xiaomi.eu_multi_MI10_V11.0.25.0.QJBCNXM_v11-10
Downloaded the Xiaomi.eu ROM to PC, then copied to the Download folder of the Phone.
Started phone in upload mode or TWRP. > Wipe > Swipe to Factory Reset + Format Data.
When formatting data I erase all folders in the phone, including the Xiaomi.eu ROM copied in the Download folder.
Some tutorials suggest to copy the Xiaomi.eu ROM from PC to phone after formatting the data, just by connecting the phone in TWRP to the PC, by going to > Mount and enabling MTP.
Tried this method but when I send the Xiaomi.eu ROM file to the phone the progress bas doesn’t move.
So I restarted the phone, without installing the Custom ROM, went through all the screens of initial phone configuration. Lost Magisk and root (but I supposed that it’s not mandatory to install Custom ROM). Copied again the Xiaomi.eu ROM zip file to the Download folder. Rebooted to TWRP. This time I just did Factory Reset but without Format Data. Then > Install to install the Xiaomi.eu new ROM. Cleared Dalvik Cache then reboot.
PROBLEM : bootloop. Stuck with the 5G logo forever, waited more than 30 min, no change.
Still have access to recovery TWRP and to bootloader mode. I suppose this is a soft brick?
I did > Wipe, Swipe to Factory Reset + Format Data, restarted… no change.
Copied this time the Xiaomi.eu ROM to a clean formatted (FAT32) USB drive. As shown in some tutorials, you can us an external USB drive via USB OTG to install the Custom ROM via TWRP.
Factory Reset + Format Data, then I installed again the same Xiaomi.eu ROM from the external USB. Still stuck in bootloop.
Please I need help to fix the problem
I’m not an expert developer, but I’m not a complete noob either.
This is the first time I have troubles with a brand new Xiaomi Phone.
It’s the first time I get a very expensive phone, but had no choice (they are getting very expensive), because I always buy a Flagship Xiaomi to get all the community support possible.
And I had to change the ROM to Xiaomi.eu, because the Official Global ROM is full of bloatware I had a good experience with Xiaomi.eu ROMs with my old Xiaomi Mi 4 and Mi 5.
At this point I don’t mind going back to stock MIUI Global ROM.
I suppose that with access to boot loader I can flash the Official ROM from PC with MiFlash2020-3-14-0? If it’s the case can somebody show me detailed steps to do that?
For Mi 10 Official Global there is the Stable Full ROM (miui_UMIGlobal_V11.0.2.0.QJBMIXM_4f986c08cb_10.0 ) (2.45 GB) and Stable ROM (umi_global_images_V11.0.2.0.QJBMIXM_20200328.0000.00_10.0_global_09b168ff9e) (3.76 GB). Which One to flash from PC with MiFlash?
I can’t afford to hard brick the device
Thank you very much.

Lost Magisk and root (but I supposed that it’s not mandatory to install Custom ROM). Copied again the Xiaomi.eu ROM zip file to the Download folder. Rebooted to TWRP. This time I just did Factory Reset but without Format Data. Then > Install to install the Xiaomi.eu new ROM. Cleared Dalvik Cache then reboot.
PROBLEM : bootloop. Stuck with the 5G logo forever, waited more than 30 min, no change.
Still have access to recovery TWRP and to bootloader mode. I suppose this is a soft brick?
I did > Wipe, Swipe to Factory Reset + Format Data, restarted… no change.
Copied this time the Xiaomi.eu ROM to a clean formatted (FAT32) USB drive. As shown in some tutorials, you can us an external USB drive via USB OTG to install the Custom ROM via TWRP.
Factory Reset + Format Data, then I installed again the same Xiaomi.eu ROM from the external USB. Still stuck in bootloop.
Please I need help to fix the problem
I’m not an expert developer, but I’m not a complete noob either.
This is the first time I have troubles with a brand new Xiaomi Phone.
It’s the first time I get a very expensive phone, but had no choice (they are getting very expensive), because I always buy a Flagship Xiaomi to get all the community support possible.
And I had to change the ROM to Xiaomi.eu, because the Official Global ROM is full of bloatware I had a good experience with Xiaomi.eu ROMs with my old Xiaomi Mi 4 and Mi 5.
At this point I don’t mind going back to stock MIUI Global ROM.
I suppose that with access to boot loader I can flash the Official ROM from PC with MiFlash2020-3-14-0? If it’s the case can somebody show me detailed steps to do that?
For Mi 10 Official Global there is the Stable Full ROM (miui_UMIGlobal_V11.0.2.0.QJBMIXM_4f986c08cb_10.0 ) (2.45 GB) and Stable ROM (umi_global_images_V11.0.2.0.QJBMIXM_20200328.0000.00_10.0_global_09b168ff9e) (3.76 GB). Which One to flash from PC with MiFlash?
I can’t afford to hard brick the device
Thank you very much.

Hello,
i have a silly question about step 4:
someone says we should "Wipe Data", someone says we should "Format Data" ,
i don't see a real difference unless we want to change the filesystem type.
Advices ?
And also, when we format ( or wipe ) the "Data" partition, are we formatting the 256 GB partition ?
if yes, this is a really huge drawback for us who want to change ROM more frequently than other android users, because we have to backup a 256 GB partition ...
This is not fast to do online ( at least with my poor connection ) and it is not fast to do on PC or on a USB KEY.
So we have 256 GB and we need to format at each ROM change ? Too bad ...
In the good old times i did extract my microSD card and i was safe .
Someone could explain me please ?
thank you all for your patience...

Hello,
You have to format data the first time you flash xiaomi.eu rom because their rom is base on Chinese firmware (if you don't or just wipe it will not boot)
Each time you will flash a rom with different base (from Chinese base to global base or global to Chinese) you will have to format data !!

You format data to remove encryption.

Stuck without solutions
Hello,
I tried to flash the latest miui 12. I followed all the steps...
But now I can't acess recovery nor rom.
Basically when i try to flash TWRP with bootloader it just goes back to fastboot.
Also note that the flash is successful. But I somehow can't acess TWRP, just goes back to fastboot
And when I flash the experimental TWRP on the dev thread it boots to recovery but asks for a password.. Impossible to flash anything.. Even after I formated data and everything
I tried flashing other TWRP I found but nothing boots even after trying a lot of time.
I tried <fastboot boot recovery.img> as well
I tried <fastboot erase recovery> and then flash the TWRP as well
I've been trying hard for the last 8 hours.
I also have a backup of when I had MIUI 12. But impossible to flash it with the only recovery I can boot to.
I feel so desperate. I'm out of ideas.
If you have any ideas, I'm listening
Thanks for the help guys.
