I am trying to resurrect my old Samsung Galaxy i5500. A couple of years ago I tried installing some custom rom but failed and bricked the phone. The boot process halts at the Samsung logo (the very first logo to appear.)
Putting the phone into recovery mode (using the volume down button + center button + power button) works, at least i presume that it works - the logo with the android shoveling dirt and the word "Downloading..." beneath it appears - but neither adb nor fastboot can see the device.
My troubleshooting so far:

Thanks!
The "recovery mode" that you mentioned, is actually download mode and it's used to flash packages with Odin.
Use it to flash a custom recovery and then use that to flash a custom ROM. Format /system and /data as ext4 before flashing the ROM.

Hi,
I just briked my TF201. I have only the Asus screen and the "The device is Unloked." notification.
If I restart my TF201 and hold vol up and power, on my Linux I found it like:
Code:
usb 1-5: new high-speed USB device number 6 using ehci-pci
usb 1-5: New USB device found, idVendor=0955, idProduct=7330
usb 1-5: New USB device strings: Mfr=1, Product=2, SerialNumber=0
usb 1-5: Product: APX
usb 1-5: Manufacturer: NVIDIA Corp.
mtp-probe: checking bus 1, device 6: "/sys/devices/pci0000:00/0000:00:02.1/usb1/1-5"
mtp-probe: bus: 1, device: 6 was not an MTP device
The TF is reconise under Windows too with the APX driver.
So I think I can use nvflash.
My question is there is any solution to unbrike my TF201 by using old TWRP bakup ? (I have the original configuration too)
Regards
Totorux
Your nandroid will only help if you can get to twrp. You should've used NVflash to generate the blobs, without thosr blobs NVflash will not help you

Sorry to say, but as you don't have the nvflash back up files APX mode is of no use to you, try buying a second hand motherboard of eBay and replacing it
Sent from my TF300T using XDA Premium HD app
Hi, suddenly (without any ROM flash attempt) my IAIWAI AW920 tablet got in a bootloop.
IIRC it's a RK3066 but the RKAndroidTool/Finn Flash Tool didn't recognized the tablet with either PWR Vol+ or PWR Vol- boot modes.
In the past I got the tablet successfully rooted through some tools, so in some past era I was able to communicate with ADB from the Android SDK (Linux Mint Kernel +3.10) but before it got soft-bricked I had not the USB debugging bridge set and due a failing HDD I lost that environment setup.
While being connected to my laptop through USB cable I can access two modes:
USB + PWR + Vol+: Blank black screen but I detect a USB device with VID: 10d6 PID: 10d6 that doesn't seems to be an adb client.
USB + PWR + Vol-: Appears a Fastboot kind of picture (Android mascot laying in the floor with his chest open and a Red Warning Symbol ) but no output whatsoever in [dmesg] or [udev monitor]
In neither these modes adb or fastboot detect something
---- For the Vol+ mode with the 10d6:10d6 device ----
I can't get adb or fastboot to work, even with adb_usb.ini edited in windows or linux or several different udev rules
The only udev rule I could trigger was
#IAIWAI
SUBSYSTEM=="usb", ENV{ID_VENDOR_ID}=="10d6", SYMLINK+="android_adb", MODE="0666", GROUP="plugdev"
Click to expand...
Click to collapse
But it seems android_usb is not a link to a proper block device (the last number increases on each test)
ls -l /dev/
android_adb -> bus/usb/001/010
Click to expand...
Click to collapse
Or at least I can't make it work with
adb -p /dev/android_adb devices
or
fastboot -s /dev/android_adb devices

I'm having problems with a Chinese tablet that I believe to be a Mediatek TAB910 with a MTK6592 processor.
It started by having problems with the SIM slots which I put down to a faulty SIM card. I obtained another from the telco but that didn't solve the problem. I concluded that the problem was with the SIM slots or with the software so I did a factory reset.
That appears to have gone well EXCEPT that I cannot get past the "Enter Privacy Protection password" screen (PPP). Let me say at this stage that I have never used PINs on my SIM cards; in fact, if I put a SIM card in which has a PIN then the screen asks for and accepts the SIM PIN but still presents the PPP screen.
I have tried to connect to the tablet by USB in order to try SP FLASH, but that tool doesn't see the tablet at all.
I then tried sudo dmesg|grep usb to see if there was any recognition of the USB and got the following results:

It appears that the tablet is identifying itself, but immediately disconnecting again, hence no response from SP FLASH.
I can get the tablet to drop into two factory setting levels, one with English language instructions, the other with Chinese language instructions. Both of these appear to work as expected when I run through the menu items including, in the Chinese menu, "Eliminate eMMC".
I have also modified the udev files, but seemingly to no avail.
~$ cat /etc/udev/rules.d/80-persistent-usb.rules
SUBSYSTEM==”usb”, ACTION==”add”, ATTR{idVendor}==”0e8d”, ATTR{idProduct}==”2000“
SUBSYSTEM==”usb”, ACTION==”add”, ATTR{idVendor}==”0e8d”, ATTR{idProduct}==”2002“

Thanks for that but I have already been down that rabbit hole without success. My big problem is that the USB comes up but promptly disconnects again
Usually MTk preloader comport will disconnect if correct bootloader is not detected. So check you've got MTK6592 supported sp flashtool version and original firmware loaded. For privacy protection removal you need to format whole flash except bootloader and flash origin firmware then need to repair imei.
For some models you need to press and hold VOL+ or VOL- or both to get in to flash mode.
