[Q] Need Help Rooting Cello 7" Tablet - General Questions and Answers

Hi guys, im not a noob when it comes to rooting but this new tablet is giving me a headache and i dont know what to do now.
So far, I have tried many one click apps, even ones for the pc... Even chinese ones and nothing has managed to root it.
Here is the device details...

Any advice on how to obtain root would be fantastic.

Update
Right, I read on another forum about Chinese phones and tablets with a certain type of chipset can have the firmware / rom copied directly from the device in the form of a scatter file which you then use to create the image on your pc.
I already tried the tools but unfortunately, the software is not compatible with my tablets hardware.
I have now sent an email to the manufacturer explaining that my tablet is stuck in a bootloop and even the reset pin and recovery modes won't work and have requested a copy of the original firmware to flash to my device.
If I am successful in obtaining a copy of the firmware / rom, is there a guide explaining how to modify it in order to root it and how to make a recovery compatible with my device.
At the moment, this is all relying on me getting the firmware / rom from the manufacturer but, if I am successful, I will share my modded + rooted rom with the rest of xda.
While I am waiting for a response from the manufacturer, does anyone know if it is possible to "rip" the current rom / bootloader / etc from the tablet, just in case they don't send me the files I requested?

Any news on this at all? I have an 8inch cello win 8 tablet that won't start up so any future info on cello tablets would be handy.

Any news?

[Q] Yarvik TAB360 runing on Gingerbread

Hi, first of all i am a noob and i want to apologyze for my english wich is not very good.
So... i've got a Yarvik Tab360 tablet wich runs on Gingerbread 2.3.4. kernel 2.6.36 wich i have allready rooted by zergrush exploit. What i want to know is how can i do ROM backup because i could'nt find any hint how to make CWM work on this tablet. I've allready tried to do like in Froyo Android 2.2.3 with flash_image but no success, the OS is diferent. So if you have any hints about this and if theres a way to install a nice custom ROM or Honeycomb, ICS... please let me know, i'll be glad to test. Another thing that drives me crazy is that i cant use properly App2SD ,because my microsd is mounted as .../mnt/extern_sd and internal storage is mounted like .../mnt/sdcard. There's a way to make internal storage as a single partition? because right now is splited in 2 partitions like one for system files and another for cache and data; or there's a way to configure App2SD to move data at .../mnt/extern_sd not on .../mnt/sdcard how it is set by default? And there's a way to pack my system files in a zip archive and restore it by recovery console like by just pressing on install update.zip?
Here is some info about my hardware so maybe someone knows a popular tablet with the same conf.

[Q] [Generic Device] Howto upgrade OS inside the img file

Recently i was given an android device by a friend.. once i got to looking around at it, it appears to be some generic device from china.
After searching for days, i found the maker as fugetek. I emailed them asking for a release date on OS upgrade (from 4.1.1 -> kitkat) and was informed that " Updates are needed, and won't be made. "
Emailed them again asking for the source / project files they used to build the android OS for this device so i could update it myself...
Here is what they sent me:
(image attached)
As you can see.. these are hardly project files / source files, but rather a flashing tool, a set of " how to " doc's for flashing the device, and a compiled *.img
My Question:
1) Is it possible to extract / mount the img file, and manually upgrade the OS to kitkat witout losing any hardware functionality
2) If it is indeed possible to upgrade the android OS version using the img file as src, does anyone know of a step-by-step guide / tutorial on how this is done.
[EDIT] UPDATE: Seems the PheonixUSBPro flashing utility links to an " Alwinner " PDF when you click help..
I am assuming this is pretty much the same image being passed around by the chinese for their generic 7" Android Devices
From what i'm reading.. this is going to a fun, and somewhat convoluted project
Device Details:
Manufacturer: Fugitek Technologies / Lonestar Group:
Model: OCOCCI_MID
Android: 4.1.1
Baseband: jellybean
Kernel Version:
308+

Build Number:
nuclear_pfdq88d-eng 4.2.2 JRO03C 20130913 test-keys
Any help would be most appreciated
If anyone requires the " source " zip they sent me, let me know, and i'll upload it somewhere for you.

Need help with root or custom recovery myPhone L-Line

Hello,
I need help with rooting my new device - myPhone l-line. This is typical Chinese phone rebranded by Polish company myPhone. It runs Android 5.1 on MediaTek MT6735M with 1 gigabyte of RAM and 3000mAh battery. I tried everything: oneclickroot, Kingroot (PC and APK), Kingoroot (PC and APK), framaroot (device not supported), towelroot (not vunerable to exploit), 360root, Baiduroot, rootkhp and many other metods and my device seems to have very good security background (i am simply amazed by the way, because this device is low-budget phone, about 80$ in my country) and there is no custom recovery to download. I have Oneplus 2 (previously Oneplus One and Nexus 5) phone as my second device and i am really into changing ROMs, recoveries, rooting and modding Android, but i don't know how to crack this myPhone. If there is no option to root this device, i will be very grateful if someone can tell me how can i remove bloatware without root, because this fone is full of uneccessary aplications, which occupy memory and slow down the phone. This is the only reason i want to root this smartphone. Please help me with rooting or if someone know how to compile custom recovery for this phone, i will be very grateful if someone could post it here, i will probably know how to change stock recovery in this phone to custom one (this device seems to have unlockable bootloader, thus i think that custom recovery can be sent to phone via fastboot). Thank You very much for any help and please forgive me if i make any mistake in this post, English is not my mother language. Below You can find full specs of this phone:
Processor: MediaTek MT6735M
Screen: 480 x 854 px (4,50")
RAM: 1GB
Internal memory: 8GB + microSD support
Dual SIM
Rear camera/front-facing camera: 5MPix/2MPix
LTE baseband support: 800, 1800, 2100 MHz
OS: Android 5.1 Lollipop
version of the baseband: MOLY.LR9.W1444.MD.LWTG.MP.V8.P28,2016/01/05 20:21
kernel: 3.10.65+ [email protected] #1, Tue Jan 5 20:31:51 CST 2016
complilation: L-Line_PL_V1.0.9
Android security patch: 2015-11-01
EDIT: I already unlocked bootloader, then i get scatter and stock recovery.img. If these files are needed to compile custom recovery or to get root access - feel free to PM me, because i can't post external links, but still i can send You these files via e-mail.
Cheers

GHIA Tablet - ONLY AGILE B a.k.a AGILE A7i

So I have this tablet, thanks to my little nephew who loaded it up with tons of games and viruses/ads (he's 8 yrs old) so he asked me to repair it for him. My problem is that I can't seem to find any relevant info on this tablet, not even on the manufacturer's website , which i find truly strange not to find it there and it's not a very well designed site either. Does anyone know of any software for this tablet to restore or upgrade firmware on this equipment? Can it be TWRP'd or CWM'd?? Are there any Custom ROM's for it? I'm kind of assuming most answers will be hard no's due to the Intel Processor in this thing.
According to CPU-Z this are the specs:
Processor: Intel Atom (TM) CPU Z2520 1.20 GHz
Cores: 2 (4 CPU's)
Architecture: x86
CPUID: 6.35.1
Codename: Saltwell
Model: ONLY AGILE B (GHIA-pn)
Manufacturer: GHIA
Board: GB7_GEN_CN
Hardware: redhookbay
Screen; 6.94 inches
Resolution: 600 x 1024 pixels
DPI: 170
RAM: 1024 MB
Internal Storage: 3.85 GB
OS: Android 4.4.2
API: 19
Bootloader: Droidboot Provision OS v.2.0
IFWI version: F9.FD
Product: GHIA-PN
BUILD ID: G02TJET_A442_X04_006_607PRS_ES
Java VM: Davlik 1.6.0
OpenGL ES: 2.0
Kernel Arch.: i686
Kernel Version: 3.10.20 (eng.aily.20150128.132500)
Root: NO
Google Play Svc.: 20.15.16 (000700-309763488)
UPDATE 5/30/2020: I contacted the manufacturer GHIA and they responded quickly indicating this tablet is supposed to match up with the GHIA Agile A7i and even provided me this direct link to download the manual and firmware updates. It contains the IntelAndroidDrvSetup 1.1.5, iSocUSB Driver 1.0.1, and PhoneFlashTool 3.1.8.2 (win32) executables. I couldn't get the 1.1.5 or 3.1.8.2 files to launch, it gave me a "admin user has blocked these programs..." error msg even though I ran them as Admin. So instead, I downloaded updated versions of these programs and they installed fine (IntelAndroidDrvSetup 1.10.0, iSocUSB 1.2.0 & PhoneFlashToolLite 5.8.4.0). I was able to flash the firmware using PhoneFlashToolLite 5.3.2.0 which did give the tablet a better touchscreen response and eliminated the lag i saw originally (process is rather lengthy), but it did remain on kitkat 4.4.2 and no root access. It does offer the option to apply firmware updates locally via the system updates menu (online updates wouldn't connect to network), but I couldn't locate the correct directory in order for the system to recognize them that way.
I'm not familiar at all with the Droidboot Provision OS bootloader, albeit it looks pretty cool and useful. Unfortunately I couldn't find adb/fastboot commands that work with it to unlock the bootloader and be able to flash a custom recovery like TWRP/CWM (perhaps ported?) or get a custom ROM on it either. One major flaw i did noticed though is that not many games from the Google Play Store work at all even though they install but just FC. Surprisingly enough, it did allow you to uninstall any app it comes bundled with, so good for bloatware cleanup. I welcome any feedback anyone may have on this little tablet.

Flashing a custom Android on a no-name tablet / phablet

Hi,
I just bought a cheap no-name phablet (tablet with SIM card slot) on eBay (used, I want to use it for my doorbell system). It has an Android 8.1.0 on it and the settings say it's a model "K4", serial number
Code:
0123456789ABCDEF
(which perplexed me a bit in the first place), the boot screen says "MediaTek" which I found out seems to be the CPU's manufacturer. Build number is
Code:
O11019 test-keys
and kernel version is
Code:
3.18.79
. The ebay article said the tablet manufacturer was Padgene which I couldn't find any information about (except for this Amazon article).
Now I somehow fear (for the serial number alone) that this is some kind of weird Chinese Android ROM no one knows what it really does in background. And so, I want to flash a custom ROM on the tablet.
Now my questions:
1. How is it possible to find out the real hardware manufacturer to find out which Android ROM I would need?
2. Are there even custom Android ROMs out there for those Chinese no-name tablets at all?
3. How do I flash it, should I use TWRP for it or choose a different way?
Thanks in advance, taiBsu
Not the manufacturer is of any interest, but device's hardware.
