Roadstar RD9200U - sec_smdkv210 - Can't backup current OS image - Android Q&A, Help & Troubleshooting

Hi,
I am software developer. I have a Roadstar RD9200U car stereo and i want to modify os, apps or develop new apps. I rooted device with z4root but before starting i want to backup currently running os. If i make mistake i want to restore original os. CWM and TWRP are not supported this device and i can't backup current os. How can i get os image and restore? Below is my device info.
There is not a usb connector for PC but two usb hosts. I can connect with adb over wifi. If i push eject and power button while power off i think the device is searching image from sdcard and then power off. ADB backup command is not working it says that "closed".
Thanks,

[q] how to get firmware and hardware info on china brands

Hi all, I'm from the Philippines and I currently bought a China tablet called TORQUE - DROIDZ FLASH. I want to root this tablet and install ROMS on it but How do I retrieve full info of the tablet with regards to Firmware, Hardware, Kernel, Original Manufacturer and other important information that may be used for a smooth rooting process and Rom installations.
The tablet doesn't have a developers config for debugging usb access... But when mounting USB drives, and using ADB, the tool has detected the device as 20080411...
I have used UNLOCK ROOT application for windows, and it detects it as Unknown Android Device, and when rooting it displays the message "Device already Rooted, Do you want to root again?"
If this is the case, I just needed to install CWM recovery (but how?) and determine the correct ROM to install...
Can anyone help me on this?

Chinese tablets and smartphones usually are created on the popular soc (system on chip). In many china markets like pandawill, aliexpress, etc there are more or less complete desciptions for china devices. In this information you can find processor name/series. From another sources you can find usb drivers for this processor. After installation you can debug your Android app on your china-noname tablet. I have Freelander DP10, based on mtk6575. After unpack device from box, it was not "visible" by ps. After installation mtk65xx drivers (found somewhere in internet) i can debug app on my device. Hope, you can do the same.
Some sources says, that you have Rockchip 1.2 MHz processor. There are a lot of Rockchip usb drivers available

[Q] Using dd for backup and restore in Qualcomm disk mode

Hi there,
I'm using a carrier phone right now, specifically, Smartfren Andromax-U LE. It's packing MSM8625Q (Quad-core Cortex-A5 1.2Ghz), 1GB RAM, 4GB Internal, 8MP camera, 4.5" IPS LCD (540x960, 240 dpi)
Here's what interesting to me, when I searching button combinations to bring me to recovery mode, I found a mode that is supposed to be qualcomm disk mode (Windows suddenly told me to format it, meh), and then I tried to plug it in ubuntu, and there's some disk showing up (including android root, FOTA partition, and many more).
So, I was thinking, can I backup the entire internal memory (all 4GB of it), and then restore it back (in case something's go wrong) with dd command?
(This question is moved from here)
commissions fronmpt
I would usually say this is a good (and better/easier in some ways) way to do a backup/restore but if its reading files from that partition/drive while its in its fastboot/recovery, it might mess things up. Its probably safer to mount the partitions and tar/zip them up unless your sure its reading the recovery/fastboot stuff into a ramdisk before running it.
It is not in fastboot mode, fastboot won't detect the phone. It's similar as nokia lumia series. Maybe if I backup the partitions one by one, it will give the result that I want, but not the simplicity
imp

Actually, my friend did this, and his phone come back to life, but his IMEI is same as mine (can later changed with another software called DFS -I think- )
Here's what you gonna do if you want to get your phone's life back
Get a raw image from your friend's phone (must be the exact same phone)
Firstly, enter Qualcomm disk mode, and then plug it to PC, and type this in terminal (you must running linux to do this, not windows)
Code:
dd if=/dev/sdX of=~\raw.img
change X with your corresponding drive (it's usually sdb, or sdc)
and then restore it to your phone (unplug you friend's phone, and plug yours)
Code:
dd if=~\raw.img of=/dev/sdX
Good luck!
P.S.: after this, your phone (hopefully) will boot again, but the IMEI will be the same as you friend's

[Q] Retreive Files from Bootlooped ATM7029

This was originally posted over in XDA Assist (Thread over here) but was recommended I post it over here to see if people could help. Pardon the copy paste.
A friend of mine that I gave a tablet to left it in a hot car and now it is bootlooping. She has a bunch of photos and documents that were written on the tablet that she would like to get back. The only trouble is that this tablet is one of those Chinese Action ATM7029 clones with little to no information on the internet about them. I figured out the combos to get into the stock recovery and do have access to SD cards to load recovery images onto it. ADB bridge / debugging was never turned on in the tablet so going into recovery does not create an ADB link. Here are the details:
Device: FastTouch 10" 8gb
Android: 4.2.2
Processor: ATM7029
Memory: 8gb flash / 1gb ram
ADB Enabled: No, USB Debugging was never turned on
Recovery: Accessible, but only stock version
SD Slot: yes, 8 and 32gb SD Cards are available to be used
Computers and Operating systems: I have a Mac with 10.8 with ADK 'installed', access to a windows 7 machine available
(Amazon link to the device: amazon_com/gp/product/B00ECKG0XK/)
Here is what I have done:
1) Got into recovery
2) Tried wiping cache and rebooting, still stuck
3) Tried ADB from a Mac machine, not recognized (ADB was not turned on in tablet)
4) Looked for any sort of recovery for the device. Sketchy possibles, no direct compatible found
5) Posted here.
Here is what I want to do:
1) Get the files off (if possible)
2) Get the device working, even if that requires wiping the files out (if possible)
Can anyone point me to a CWM or TWRP that would work with this device and let me form an ADB link to backup with? Even if the recovery ran out of ramdisk and didn't install that would be enough. I really want to get those files back out before doing dastardly things to the device. Thanks in advance for any help that can be provided.

First hardware steps for new ROM - NAND Backup

Hi,
I have a AN6B01 based Cortex A8 android car radio and i want to create custom rom for this device. I am software developer and i have electronics knowledge.
Firstly i want to backup nand but this device has not usb port for connecting to PC. It has usb host ports for connecting modem, wifi, etc.
I rooted device but there is not a supported nand backup software. I tried wifi adb and similar apps but no luck.
I disassembled device and investigated circuit. There is usb hub chip and all usb ports connected to it (smsc usx2064).
1- If there is a usb port for connecting to PC how can i find it in circuit?
2- I can access nand chip on circuit. How can i backup and restore nand with a reader/writer device in circuit?
3- Is there an another solution for backing up nand and restore (software or hardware solution)?
I can't upload images because i am new user. If you want to see circuit images i can send you.
Thanks,

Archos 50 Diamond - how (is possible) to custom recovery or ROM without touch screen

Hello, i have Archos 50 Diamond with stock Android 4.4.4 Kitkat:
gsmarena.com/archos_50_diamond-7042.php
archos.com/us/products/smartphones/diamond/archos_50diamond/index.html
postimg.cc/gallery/ctjgb6yk/ (images of Archos 50 Diamond internal parts and removed LCD glass, digitizer and battery)
Issue: Phone is restored to factory default, screen displays good, but is cracked in the corner and touch does not react.
My aim is to run Android app on it and be connected to the internet via WIFI or run general Linux app like SSH, rsync on any ROM that would work on the device.
So i need to somehow control the device via either USB (manufacturer says MicroUSB V2.0 support), bluetooth or via wifi (i read some apps can manage phone via wifi thanks to higher android version (maybe lolipop and up).
1.
I want to ask if i can connect USB hub with the mouse and keyboard or if there is hardware limitation. I tried to connect the mouse, but it not shown any cursor in post installation menu after boot (where one select language).
If there is a SW limitation, i found there is Android 5 Lolipop beta (blog.archos.com/en/beta-version-of-android-lollipop-for-the-archos-50-diamond/), but i am unsure if i can use that update.zip on sd card and update from sd card in stock recovery menu. (from the article they speak about internal storage)
2.
Next question is if i can use some "update from SD card" package that would enable ADB and USB debug mode or
3.
if there is any ROM for this phone that would support connecting USB peripherals and WIFI. I found no ROM for this exact Archos phone.
4.
is there any custom recovery for this phone? i also not found any that would indicate this phone type
5.
is there any package for rooting the phone via stock recovery "update from SDcard" function?
6.
the repair of the touch function is doable by me or for low price under $50 ?
Thank You
