I went into the recovery mode and connected again.. now the MTP mode is working fine.
But it doesn't work within the OS.

Hisense u989 Pro - No OS installed

Hi,
I have a Hisense u989 pro with a custom recovery installed, I performed a restore from a previous backup. After completed, when wanting to reboot, I saw a msg "No OS installed, leaving the phone connected to my pc and charging via usb, my wife needed a usb cable and unplugged my phone. when I returned some time later the phone was completely dead.
Some issues: Phone not charging or switching on, cant boot into recovery or fastboot, sp flash tool not detecting phone via usb cable, tried different usb cables, cleaned the micro usb charging port. left phone connected to charger for over 24hrs and still nothing. Im unsure whether it could be the charging port or the battery.
Ive got the hisense u989 pro stock rom, i just need it to switch on. Any advise or assistance to resolve my phone issue will be appreciated.\
thanking you

Unbrick Onda V701s tablet

Hi everyone!
I have an Onda V701s tablet that runs on the Allwinner A31s SOC. Specifications of this tablet can be found here: https://www.imei.info/phonedatabase/onda-v701s/
While trying to root the tablet with ADB commands, I bricked the device. When powering on the device, it is stuck on the Onda boot logo. This boot logo shows the brand logo with the text "SINCE 1989" underneath it. The device does not boot any further, no matter how long I wait.
I've tried to connect the tablet to my Windows 11 (64-bit) laptop in a special download mode using the following steps:
Power off the tablet
Press and hold volume button
Connect USB cable from the tablet to the laptop
Press the power button up to 10 times until the tablet is recognized by the laptop
These steps indeed result in a different connection between my laptop and the tablet, but I am still unable to flash the stock firmware. To do this, I've tried LiveSuit and PhoenixSuit, but both pieces of software do not recognize the tablet (no device connected).
Does anyone here have experience with flashing bricked Allwinner chipset devices?
If more information is needed to solve this issue, please let me know
yo ask this guy on fivver he knows everything https://www.fiverr.com/mateenqamar564?source=inbox
