Chuwi Hi9Air CWI546 - Android Q&A, Help & Troubleshooting

Hi everyone.
It's been one year I'm trying to mod my tablet Chuwi Hi9Air without big results. :crying:
I've started successfully unlocking the bootloader.
Then after few failed attempts to install a custom rom I've bricked my tablet.
Now I've managed to install a twrp and a stock rom (O000623 release-keys 20181122) with SP Flash tool.
Here the problems:
1. I don't manager to root the tablet
2. In the shell on my pc when I type *adb devices" as result I get 0123456789ABCDEF. I've already tried to look for a solution online but I didn't manage to solve the problem.
3. Trying to follow some guides I did not managed to recover /data /system and /cache.
I don't know if the problems are correlated, but I would like to solve all of them.
I thank everyone who will try to help me. :fingers-crossed:

I hope so. ?
Finally I succeed in installing a non standard recovery and in getting root permission.
I don't know if someone is still interested in such device, but here is the material you need.
In the enclosed zip you'll find:
recovery.img: it's a PhiltZ touch recovery (based on CWM), the only one I got working because it uses the phisical buttons of the phone. In this device the touch is not working in recovery mode. I tested all the main functions (wipe, install, backup e restore), and they are all working, the minor ones are untested. This recovery reads and writes only from internal storage (not from the external SD). To install it, you need "SP Flash Tool", which can be downloaded from Mediacom site, in the relative device page.
MTK_AllInOne_DA.bin e MT6735M_Android_scatter.txt: are the "download-Agent" and the "Scatter loading file" you have to use in SP Flash Tool to flash the recovery. The scatter file is already setted to flash only the recovery, not other parts of the firmware. Be sure, before flashing, that only recovery item is checked in the Download page of SP Flash Tool, with the proper recovery path in "Location".
BETA-SuperSU-v2.52.zip: it's the zip archive to get root permission. Install it via recovery, after you have tested that the recovery is working for you.
recoveryORG.img: it's the original recovery, for restoring purposes. Install it (if you need to restore your phone to the original state) with SP Flash Tool, in the same way.
N.B.: Of course, I do not take any responsabilities about brick or problems may occur to your phone after using this material. . If you decide to use it, you do at your risk, aware that this type of changes always involves a minimum of risk if something goes wrong.
Herewith enclosed the archive:

Coolpad E501 EU unbrick, reviving

Hi
I have Coolpad E501 EU (other names: Modena, Y76, Sky). It's dual sim, stock android 5.1, rooted, stock recovery.
After last mini update (9,2 MB) coolpad logo is showing and then it goes only to recovery. Phone was rooted using KingRoot app, and then applied update so I bet it was a mistake to do so.
I have second one same Coolpad phone - working, rooted, stock android, stock recovery. So it might help in restoring bricked one.
I searched almost everywhere on the internet looking for stock roms, recovery or something that I can flash.
I tried using YGDP tool with 4.4 official rom that I found but no luck. I get the message "Bootloader is old" in logs.
Tried to do backup with nandroid of working phone but it's making backup for custom recovery (cwm - .tar or twrp - .wim). My phone doesn't have one.
Recovery has an option to apply update from zip. Last update that messed up is here:
ota.coolyun.com/ota/Android/Coolpad%20E501_EU/P0/5.1.222.51.P0.151216.Y76_U00_5.1.222.61.P0.160510.Y76_U00/update_1464055522221.zip
I dont care about data., only working system.
Anyway I appreciate some help how to bite that, any ideas how to revive that phone. I was trying to do a system.img backup of /system partition in working phone, but no luck, partition is in ext4. I thought I can restore that using adb.
I will answer any questions if something I wrote is not clear. I'm not afraid of adb, flashed many phones, so I'm not looking for step by step tutorial, only to someone point me in right direction to solve this problem
Thanks for any help.

I found some custom roms and some software on chinese site, but cant flash them and I think it's because bootloader isn't unlocked. I tried unlocking it but no luck (using android sdk).

I have twrp for this phone, but I cant flash it. Every time I try to send a command in fastboot mode I get the message: "FAILED (remote: unknown command)". How did you flash it? Did your bootloader was unlocked in developer settings? Mine wasn't so I think I'm screwed.
Backup I have is with my personal data.

Hello ppl!
Is yours problems solved? I have soft bricked Coolpad Modena E501_EU and can't find solution.
Searching everywhere on internet, not find nothing about that phone: kernels, drivers, firmwares etc., like "ghost phone". Firmware version 4.4 is for E501-Y76-Sky but not for EU model and cannot be flashed. I need stock 5.1.222.........Y76_U00 and if can someone make backup and upload somewhere he helped me a lot.

how to root doogee bl12000

Would anyone help me get root on doogee bl 12000? This is a version without a pro so this is a different topic than this one.
No kingoroot or framaroot programs work.
I have flashtoola and rom for this phone. I tried using adb to upload files with the 12000 pro doodge but there was always some error.
I also tried to upload files via flashtoola and recovery. However, without success.
Root Doogee BL12000
Hallo there. I'm trying to root my Bl12000. I've got a TWRP from twrp builder. It works, but whatever zip file I'm trying to install I always get "failed to mount data", invalid argument. The twrp also tells me, that there's bo OS installed, but there is. Phone is working fine after reboot. SuperSu can't be installed. Full wipe is not possible, also "failed to mount" and so on.
any help ?
Tia, Chris
I think it's the encryption. Any ideas how to remove it?
Installed twrp via fastboot and sp flash tool, but I can't boot phone into it. Searched dozens of sites, no success. Flashed the twrp again with sp flash tool and according to sp it was successful. I tried several ways to boot the phone into it afterwards, no luck
My goal is to root this phone only. I'm not very experienced so if anyone could please give me a hand here and tell me where or what I'm doing wrong, that'd would be great and much appreciated. Thanks.
Ok. If I flash the twrp with Sp flash tool and type "fastboot reboot" on the adb console, sending the command while I hold vol+ and power-, the phone boots into the twrp. Next time it will be gone, so I have to flash it again. Noticed that, done.
But all this is taking me nowhere, because the encryption still prevents me from installing any zip file or format a partition. Yuck ?
Root Bl12000
Since the SuperSu method took me nowhere I decided to try Magisk. And.......HURRAY !!!!!!.......it worked.....for a moment. Booted the patched boot.img and got superuser. But with the first reboot I got stuck in bootloop. Tried again, in case I missed something, but same ****.
IT WORKS !!!!! My mistake was to assume, that Magisk works the same way as rooting with SuperSu does. So after rooting with Magisk I tried to install root apps as I was used to, but Magisk does not work that way.
Well, it'll take me awhile to figure this out ?
Why does an app keep coming back on my phone after I have done factory reset?

This Recovery is only supported for Doogee BL12000
You should have either PC or Laptop.
Make sure to charge your phone for at least 50%.
Download and install latest Doogee USB Drivers on your PC/Laptop [All Android USB Drivers]
Download the SP Flash Tool Software
VCOM driver: Download – Instal the VCOM Driver on your computer (still compatible with MT67xx phones)
Before flashing a custom recovery, you need to unlock the bootloader on Doogee BL12000
Take a full backup just in case if you need it later

HELP ME PLEASE!! My phone Vivo Y71 stuck in TWRP

Hello, I'm a beginner.
Yesterday I unlocked the bootloader on my smartphone (Vivo Y71). Then I want to install TWRP for my smartphone, but no TWRP for my Android makes TWRP, and I try to find a way to make TWRP to support my Android. After I finished making it, I installed TWRP on my Android via ADB tools, and my recovery system has changed to TWRP, but the problem I experienced started from this, TWRP asked to enter a password. And I am looking for a way to bypass this, I do Wipe Data, but I get the error code "Permission Denied" and now my Android can't boot to the homescreen, and when I reboot / shutdown my android I always go into TWRP. and now I am confused what to do, to do flash recovery via ADB can not, because the Fastboot option is not in the TWRP that I installed, and my device is not detected on my computer. Can you help me with my problem?
NP: I use google translate, my English is very bad, please understand.
Thanks.

And , regarding your TWRP encryption problem i think i can help you. Try every solution below. One might work for you.
Solution 1: Try password as " password" , it may work !
Solution 2: Try : default_password if this doesn't work.. Then am sorry my friend you have to format full data.
Solution 3: Its asking for the encryption password. The default password is "default_password" (without the quotes) try that. And if doesn't work then enter Bootloader (fastboot mode) and enter the following commands into CMD.
Code:
fastboot format userdata
Code:
fastboot format cache
Code:
fastboot reboot
This will unencrypt your phone and you'll be able to boot/enter TWRP normally.
Please do note that you'll lose ALL of your data from the commands.
Also, I'm not sure about this but you also might need to flash TWRP again.
Solution 4: Try flashing DM vertiy zip. It solves the problem (most recommended solution).

May i know what happened to your device. Have you solved the problem. Please share experience.

Question Big problem with Redmi Note 10 / TWRP - Failed to mount system_root / system_ext / etc.

Hi all,
had for a few weeks already installed the Pixel Experience Rom on my Redmi Note 10. Unfortunately, the phone could not be started yesterday (Google logo has not stopped loading), so I wanted to install the Xiaomi EU Rom via TWRP. I had probably done a lot wrong at the time of installation and that is now avenged.
About ADB / Fastboot I managed to get TWRP on my phone, but that was it. I can not get the ZIP "xiaomi.eu_multi_HMNote10_V12.5.4.0.RKGMIXM_v12-11.zip" directly from the PC to the phone. Then I put it on a SD card.
When installing I get the following errors...
Can you please help me somehow?
Thank you very much!
Best regards

First you must format the data
Twrp/Wipe/format data write YES(if red ligne error,reboot twrp and format again)
reboot twrp
flash zip rom
reboot system
If it does not work use this tool https://forum.xda-developers.com/t/guide-use-xiaomi-flash-tool.4262425/
worked perfectly with that tool, thank you so much
I used this tutorial:
How-to use Xiaomi Flash Tool to flash or install Firmware
Step-by-Step guidelines to use Xiaomi Flash Tool to Flash Stock Firmware on Xiaomi Smartphone and Tablets.
xiaomiflashtool.com
Nice
I had same problems here, but the Flash tool saved my day.
But from now on I get an message: "Gerätespeicherbeschädigung festgestellt. Das Gerät ist jetzt unsicher."
Don't know what this mean so be back on cDroid.
