Question on downgradability. I am on Version 2.9 and there is no upgrade and no downgrade update available from the ZTE website.
Can I just flash the Full EDL 1.6 on the phone without unlocking the bootloader?
So, now I am in bootloop, only the zte sign in blue shows up for a second --> disappears --> shows up again and so on.
As you probably recognized right now, I am a bit nooby here, so please be kind But I would really appreciate your help here!
Edit 1: I forgot to mention that I can press vol + and vol - to get into fastboot mode I guess. But all the options lead to the same bootloop here. The EDL Tool does not recognize the phone.
Edit 2: I managed to get into edl mode. I tried to restore my backup I made at the beginning. But there is an error, that files are missing. I see a bunch of files in the folder though. I am willing to only restore my files and leave the rest as it was. So if anyone has an idea, please help.
I figured out that one main issue could be that I should have start from Android 9. I did start with 10.
I stop editing my first post and make a new one.
I looked up the log files. I found this:
Warning: C:\Axon10_EDL_TOOL_v3.2.5\backup\all\last_parti1.bin - not found !!!
Warning: C:\Axon10_EDL_TOOL_v3.2.5\backup\all\last_parti2.bin - not found !!!
Warning: C:\Axon10_EDL_TOOL_v3.2.5\backup\all\last_parti3 - not found !!!
Warning: C:\Axon10_EDL_TOOL_v3.2.5\backup\all\last_parti4.bin - not found !!!
Warning: C:\Axon10_EDL_TOOL_v3.2.5\backup\all\last_parti5 - not found !!!
Indeed the files are missing. But why? Can anybody tell? How could I make something wrong with a backup?
Am I right that I first have to lock the bootloader to get away of bootloop? And maybe the backup will work after that? If yes, how can I do it?
Edit: Managed to flash EDL Full 1.6. Got Android 9 running right now, but still with bootloader unlocked. Which means I can not flash any stock android higher than 9, correct? So, should I lock the bootloader or should I root and flash LOS? Somebody reading this at all? :-D
!!! Whatever you do, you do at your own risk !!!"
!!! If you are not sure of yourself do not use this program !!!
Special requirements (read first) !!! 1. The program must be unpacked
2. Before using the program, make sure that:
- It is desirable to copy the program to the root of the disc, for example: C:\Axon10_EDL_Tool\ or D:\Axon10_EDL_Tool
- You launched this program as administrator
- You have drivers installed, preferably original for Axon 10
3. Read carefully what the program displays on the screen (I specially wrote the tips, the information is very useful, many questions disappear)
Features of the program: 1. Automatically reboot the phone into EDL mode
2. Unlock the bootloader for supported variants only
3. Finds the connected phone and forces the COM-port speed to 115200
4. Can flash , backup, restore
5. Analyzes folders for missing required files
6. and others ...)))
Structure of program folders: 1. Folder flash - in this folder you need to copy the files you want to flash Subfolders:
folder full - if you want to flash full firmware (official, adapted for EDL mode), then in this folder you need to put all the files from the firmware for EDL mode:
its name usually looks like this: A2020 _......._ FULL_EDL
folder boot - if you want to flash your kernel file, you need to put a file named: boot.img in this folder (the file name must be exactly that!)
folder modem - if you want to flash your modem file, you need to put a file named: NON-HLOS.bin in this folder (the file name must be exactly that!)
folder splash - if you want to flash your splash file, you need to put a file named: splash.img in this folder (the file name must be exactly that!)
2. Folder backup - the folder contains backup copies of the phone partitions created by the program Subfolders:
folder all - this folder contains backups of all partitions, except userdata
folder full - this folder contains backup of all partitions included in the FULL EDL firmware
folder boot - this folder contains a backup of the boot partition
folder recovery - this folder contains a backup of the recovery partition
folder modem - this folder contains a backup of the modem partition
folder splash - this folder contains a backup of the splash partition
3. Folder logs - contains all the logs of the program
4. Folder tools - contains all the necessary files for the program (do not touch it!)
For those who still do not understand how to flash (FAQ): Question: I want to flash the full firmware for EDL mode, how to do this ??? Answer: Download and unzip the full firmware for EDL mode, for example A2017_B17_NOUGAT_FULL_EDL and put all its files in the folder Axon10_EDL_Tool\flash\full\. Run the program Axon10_EDL_Tool.bat and select the Flash -> Flash FULL EDL
Question: I want to flash a patched or original boot, how to do this ??? Answer: Download the boot you need, rename it to boot.img and place it in the folder Axon10_EDL_Tool\flash\boot\. Run the program Axon10_EDL_Tool.bat and select Flash -> Flash Boot
Question: I want to flash the modem, how to do this ??? Answer: Download or take the NON-HLOS.bin file from firmware and put it in the folder Axon10_EDL_Tool\flash\modem\. Run the program Axon10_EDL_Tool.bat and select Flash -> Flash Modem
