Never wipe everything
Go to fastboot and flash via there the ROM, maybe even the persist partition

THX for your answer. I´ve tried to install via Fastboot. With MIFLASH but i got the anti rollback check error. I´ve read an tutorial where it stands Wipe everything execpt USB OTG. Now im Smarter...
After i installed boot.img recovery.img and system.img with the official Rom. it boots up to the original recovery.

So after you erased all but OTG, you did not install a rom? Cause you only mentioned "after that".

Try via fastboot on ADB console, not miflash.
Start with the persist partition and then flash TWRP again and flash a ROM that you are positive that TWRP flash fine (some don't). Stock MIUI i'm speaking.

Yes did it with ADB fastboot. I can install the Rom complete fine but nothing works. I´ve tried with TWRP. Will do that again.
Im Sorry you mean first: flash persist.img? and then the twrp recovery and after that install the rom over twrp?

Soo I flashed an older version it works. But No Wifi i will try to Update it over LTE. Do i have to flash the persist.img ?
Everything is fine now! Thank you for you´re Help!

If the sensors are not working (gyroscope, camera, etc) you will need.
If you solve the Wifi issue then no need

Can't go back to stock system, no fastboot, no adb

Hello my friends.
I have here a zenfone 5 with pinaslang twrp 2.8.6.0. Any usb function dosn't work with it. Can't use fastboot, adb or mtp. I have another one here, same model, and all this works, is not a pc-driver problem.
I want to return to stock system, but as I don't have access to fastboot, it's been a struggle.
I've tried replacing the internal board that contain usb plug with the other zenfone I have, but it didn't work.
Nandroid backup in the good zenfone and restore to the bad one didn't work, because I only found 2.8.7.0 twrp to flash, as to restore in a 2.8.6.0 twrp, it didn't recognize.
It was send to warranty, but it was void... so no deal...
That's something I can do?

Flash this package via TWRP: https://drive.google.com/file/d/0BwEWY6gMvYOeelBEQ2J0ckxnRmc/view
After that you should make a factory reset.

Then flash modded stock Rom for Asus_T00J/T00F ZenFone 5 via twrp and before flashing stock Rom wipe data/ factory reset in twrp recovery...
If you flash modded stock Rom then your bootloader will be locked and twrp recovery will be replaced by stock recovery....

Thanks for your help guys.
I flashed this file, wiped data, and got a bootloop.
Funny is that my recovery wasn't replaced.
I tried recovering with this file from ressuction rom thread:
How to go back to stock rom:
Flash this package via TWRP:
https://drive.google.com/file/d/0BwE...J0ckxnRmc/view
After that you should make a factory reset.
After this, my bootloader changed, and of course, didn't work. (the usb problem as happening before this.)
Did I brick my zenfone?

The fastboot not working maybe is a hardware issue.
If I flash a custom ROM, it'll boot. But my battery only fully work with full charge... That was what it looks.
any more help??
Sorry guys, it worked!! I don't know why, but the I let the phone to boot for more than 10 minutes, and it was looking bootloop.
Today it simply boot normally.
I'm having a poorly battery use... it's normal? Lasting 2 hours.

Phone always booting into twrp recovery mode, any solution?

2-3 days ago I successfully rooted my Moto E3 power by unlocking bootloader and installing twrp recovery. Yesterday I installed Lineage 14.1 custom Rom (7.1.2) for Moto E3 power from here
https://forum.xda-developers.com/moto-e3/development/rom-lineage-14-1-moto-e3-power-t3610435
The Rom installation was successful. Phone was working fine. But there was some minor lag and screen was appearing to be yellowish. Hence I decided to Factory reset the phone. I tried to reset it from phone settings. The phone switched off and turned on into twrp recovery mode. Then I tried to factory reset through twrp mode. But it is always booting into twrp recovery. I wiped all cache and data including system data and flashed the above Rom again. But whenever I try to system reboot, it is not booting normally, but always going into twrp mode.
Please provide solution for the issue with appropriate information and links.
Thanks.
Beauause u delete the all ROM
For Reset phone -: not need to wipe system and boot.. Only do a factory reset

Yes, I know that
I had done just factory reset earlier, but after that it kept on booting into recovery mode everytime I reboot the phone. Then I cleared system data to flash the ROM again. I should have done factory reset through recovery mode rather than from phone settings.

Update: Don't know if you still need the solution, but I am gonna share my info. Although as the phone you were talking about must be Moto E3, my phone is Lenovo K3 Note, but the processor should basically be the same, as both runs on Mediatek processors. And for the same reason, they both would use the SP Flash Tool to flash a ROM. You'll need to download the Stock ROM file for your moto E3, and flash it through SP flash tool installed on your computer. You'll get the tutorials on youtube. When the stock ROM is flashed, the phone will start with your stock ROM. I have had my phone do the same and it is fine now.

Yes i recovered from the situation.
You just had to download the sp flash tool and the stock ROM for your respective phone, and flash it . Remember for the above problem you just have to use the "download only" option in your sp flash tool and it will work. if you use "format all+download"
you will left by losing imei number of your phone and then you have to follow other procedure to fix that. but according to me your phone will start by choosing download only.

Just install the Android Studio: https://developer.android.com/studio/index.html
Let only the things install what the installer ask, restart PC and you should be able to sideload

I would:
- install TWRP again (using the stock recovery)
- Download OOS
- Put it on a usb drive
- Connect the drive to your OP5 using USB OTG
- Install OOS via TWRP

if u want to use custom rom just follow proper steps and it will install.
-unlock bootloader (which i assume u already have)
-fastboot boot latest twrp
-do a full wipe and reboot to bootloader.
-again fastboot boot the latest twrp
-now copy rom,gapps,magisk(mandatory) and twrp installer(optional)
-install rom and twrp installer only
-reboot to booatloader and fastboot boot twrp again or if u installed twrp installer just reboot to recovery.
-now flash magisk and gapps
-reboot system
By mistake if u flashed factory.bat then read this : https://forum.xda-developers.com/mi-a1/how-to/guide-how-to-restore-imei-permanently-t3759190
if your phone is rebooting after every 60 sec then u most probably corrupted /persist. Don't worry custom roms will work without any problem as they don't touch persist.
did you by chance used flash_factory.bat in mi flash tool ?

i will try to use custom rom and i hope it will work
and i did use flash_all_lock_crc.bat in mi flash tool then i'm start getting the restart problem with unread sim card
use flash_all_lock.bat only or flash all except storage.bat or flash_all.bat .except these nothing else.
flash custom rom or flash_all_lock.bat in mi flash tool (it will work work most probably).

Mi 9T Bricked - No Rom

Hi guys. I accidentaly wiped System and now my phone has no rom on it. I tried to install stock rom from https://xiaomifirmwareupdater.com via Fastboot but it won't install because of anti rollback. My Bootloader is unlocked and i have TWRP, can anybody please help me... THX!
If you can boot to TWRP, try to install a MIUI recovery rom: https://mifirm.net/model/davinci.ttt or a custom rom.
Or, try to flash the images with CMD/Terminal.

Could you describe to us the steps you did to succesfully reflash your device?
In the future in case that happend again... its easy, if you still can enter to TWRP just connect to the PC and transfer any flasheable ROM... Flash it and thats it

The TWRP method didn't work because i wiped everything : system, vendor. etc... my phone had nothing on it, not a single file of the original firmware. When i flashed the rom with TWRP it always booted to TWRP and not the rom , even if the rom was installed successfully. Even when i tried to flash with FlashTool i got the anti rollback error. The CMD/Terminal flash worked for me.
