Okay.. Bro.. I'll try..

Couldn't update ASUS ZenFone 2 laser 550kL
Facing the same problem
Baseband version - 202c10_10.0.0_160602
Build no. - WW_21.40.1220.1708.20160621
First I tried to update automatically through OTA update but failed.
Downloaded file from ASUS website (build no. 1877 ) and tried to do it manually by placing it in the root folder but still that failed.
ERROR - E: failed to mount / asdf ( invalid argument )
Please help with updation using simple method

flash stock recovery first if you want to do Gabbro16Hz method.

3gb ram varient of ze550kl has this kind of problem.
You need to download latest firmware from the asus' site. Place it in the sd card.
Enable usb debugging in developers' setting. Then boot your phone into fastboot mode. Connect phone to pc via cable.
Then put the tools.zip file in the pc and unzip it. Open that folder. Run 'flash all.bat' file. This will flash stock recivery to your phone.
Now boot phone into recovery mode. Select 'apply update from sd card. Select the firmware and flash. Then reboot. Work done. Your phone will have latest update.

I think you used sp flash tool with format + download
So ok
You have to again Flash with format + download
Why?
Because error files will format from your device
After flashing , don't power up your device
Just disconnect your device
And download sn writer tool V1.15552.00
Then extract in computer and open
Tick on , barcode,IMEI ,bt address,WiFi adress and serial no.
Then, tick on,IMEI checksum,dual imei
Then, choose your modem and apdp file
And save it
Then click on start,and fill up proper details
And now connect your Moto E3 power with usb
And it take some time
And it will show successfully pass (with green sign)
And then power up your smartphone
Now it's fix

Help with Rooting Nokia 5 (Can't bypass the checking for update process)

Hi!
I am newbies to all of these but I will try to explain.
LinkA : https://forum.xda-developers.com/nokia-5/how-to/guide-how-to-downgrade-official-oreo-to-t3746007
LinkB : https://forum.xda-developers.com/nokia-5/how-to/guide-ta-1053-downgrade-official-oreo-t3893053
LinkC : https://forum.xda-developers.com/nokia-5/how-to/root-nokia-5-android-8-1-t3831303
I have Nokia5 with android Oreo and I want to root it so I browse a lots of tutorial with zero prior knowledge and follow them.
1. I downgrade to nougat by following LinkA and LinkB <-- I use rom A02 from this guide.
2. enter download mode on my phone
3. unlock bootloader temporarily by using "Unlock Bootloader.bat" from the script mentoined in this guide LinkC
4. flash TWRP v3.2.3, v3.3.1 img files-- > I tried both but none of them work
The problem is after I flash it using "twrp flashing.bat" from the same script. I pressed power up and power button together until the phone vibrate but it just boot to the default rom that I downgraded to.
How can I boot to the newly installed TWRP recovery ?
Moreover, I can't enable USB debugging because I can't skip checking for update screen in default rom. Nokia want me to upgrade to Pie or whatever their latest version is. I tried removing sim/disconnecting wifi but it won't work. The only way I can access the phone right now is to update to Pie which is opposite to what I have been trying to do.
Edited : I tried updating as system suggested but it won't start. I am unable to use this phone now T_T
Edited 2 : I tried to flash new nb0 rom but I can't access recovery mode. It's all black. I don't know what to do now it's dead end pls help!
Anyway to fix this problem?
Thank you in advance

smt-580 locked on chinese firmware (bootloader release 5)

Hello,
On my SM-T580 (TAB-A wifi) I flashed the last official rom with odin : PDA : T580ZCU5CSF1 / CSC : T580CHN5CSF1
2019-08-23 Release 8.1.0 T580ZCU5CSF1.
The flash went well but the tablet doesn't start anymore (black screen when switching on).
when I start in "download" mode, I get the download screen in chinese ...
However it is absolutely impossible for me to flash any other official ROM.
the flash starts and then goes to fail immediately with an error message in chinese "Bootloader locked".
the message on the tablet is: SW REV. Check fail ( bootloader) Device:5, Binary: 4.
I understand that the bootloader is now in release 5 and that all other ROMs are in 4 maximum. So it doesn't seem possible to downgrade my tablet and install an official (or unofficial) rom.
It seems to me that there is no solution as long as Samsung will not develop a functional ROM with a bootloader in release 5.
Do you have a solution for a possible downgrad or to make my tablet work ?
I also tried to flash a sm-t585 bootloader with a version 5 bootloader but without success.

Hi, did you found a solution? I did the same , and I have the same problem, the only difference is that I'm able to use my tablet, I flashed the last chinese firmware from march, its functional but with no google services.

The only way to bypass a locked bootloader/downgrade your bootloader is to buy a JTAG/Riff/Octoplus box and write the firmware you want to flash directly to the board.

Hi I have the same problem,
I was looking on Sam firmware for latest firmware and saw firmware for last month for my t580
Problem was it was Chinese, I thought just change the language during setup right? And then after I oem unlock and enable adb I can flash TWRP then root.
HOW WRONG WAS I?
The problem is the firmware for the t580 in China has bootloader locked.
Not only that, the bootloader has been updated to recent firmware and the btu (UK) and other firmwares only have a patch 6months prior.
So I am screwed unless the other countries update to a later security patch so I can pass the SW rev check and unlock bootloader again.
Just so noone else tries this as it's a PIA
#####EDIT ##### To solve this problem let the tablet boot up with the error code, connect to odin and flash the Chinese firmware again, then download and install crom service apk, goto developer options and do the usual, adb enable, oem unlock. Open the crom service app and select OK/Off whatever and reboot to download mode...
Once reboot to download mode and you will see crom service off and will be able to flash twrp, roms etc again.

An error has occured while updating the device software.

Hello everyone!
Today i tried to install twrp on my s10+ SM-G765F/DS to install android 12 lineage os.
I placed TWRP at AP and VBmeta at CS.
VBmeta was stuck at the installing phase, for a very long time too.
I decided to quit Odin and unplug the phone.
Error showed up : An error uas occured while updating the device software. Use the emergency revovery function in the Smart Switch PC software.
Using smart switch pc : device dosent show up
FRP Bypass : into download mode, tried flashing original firmware, back to download mode, tried flashing twrp, didn't work, with vbmeta and without.

Please help me, i dont know what this means and whether my phone can be saved.
I have found a fix.. to everyone who is facing this problem, here is what you need to do.
1.get frija ( you will need visual c++ 2010 and 2008.)
2. obtain your model number and your csc ( found if you search up your carrier in sammobile along with your phones model number product code in my case, i got it under starhub in Singapore therefore, STH)
3. key in the details into frija
4. download the firmware from frija.
5. frija will give you a rar with your firmware, unpack that.
6. match the BL, AP, CS and CSC with the firmware and start.
The process will take a while as its a big file but your phone will be saved!
precautionary measures if you were to attempt again
1. keep the firmware files
2. use a good version of Odin, my error happened because my version of odin didnt work.
3. do a lot of research

For me with my S10+ G975F, this saved me:
