QMobile A2 Classic rooting problem - Miscellaneous Android Development

QMobile A2 Classic is a recently released phone.
It is different from QMobile A2.
It is based on MediaTek 6575 chipset.
I have tried without any success the following ways to root it:
-> Manually copying su binaries to system folder via ADB.
-> Installing su binaries from stock recovery.
-> Reading stock ROM to modify it.
-> Using all the available vulnerabilities to copy su binaries.
The reasons for not succeeding as far as I understand are:
-> Locked bootloader.
-> Stock recovery (3e) doesn't allow non-signed updates.
-> No access to download mode.
-> Locked bootloader.
Possible fixes for these issues:
-> Currently no way to unlock the bootloader.
-> Modify 3e or install any custom recovery, but root required for that.
-> Get a copy of stock ROM.
-> Currently no way to unlock the bootloader.
So, the only option right now is to modify a copy of stock ROM and flash it.
Good news is that someone has been able to read the CPU flash file of QMobile A2 Classic.
Download, credits to original uploader.
I need help in modifying and then flashing this file.
Or if anyone can think of some other way to root this mobile.

First give some information about ur phone I.e, kernel, baseband version,android version.

This device is not supported by Rom manager and clockworks.
For sony devices you need to read the device forum (As i stated above) and use flashtool to root (And flash stock ftf's) and to flash custom (Stock based) roms you need a CMW based recovery (A dev will have made one in that device forum I presume).
Furthermore, to flash custom kernel you will need an unlocked bootloader.
Sony only have official bootloader unlocking for some 2011/12 devices, so it may only be possible on this device if a dev has found an unnoficial way
very true

[Q] Karbonn A2+ ROMs and CWM?

Hello all.
I'd like to know if there's any custom roms for Karbonn A2+. I'm already guessing the answer is a "No" so I'd like to know if/how I can port any rom with JB firmware and any CWM to my device (Please tell me what rom should I take to port
The device runs on 4.0.4 ICS, with 1ghz 256mb ram, and a 4" WVGA capacitive touch screen. I've rooted it via Framaroot and am using an additional 1gb of swapped ram.
Thanks in advance.
Bump, is there anyone who can point me to the correct guide to follow?
Your phone?
What is your phone?
I mean what phone are you using?
the model and the brand?
I'm facing the same problem.
hardware config.of a2+are- mt6575 with kernel 3.0.13
brand- alps , model- A2+
hey guys.. i got karbonn A2+ replaced via company..

Interesting, could you please dump the rom?
"Jellyfish"?
Root & cwm for karbonn a2+
It is a simple procedure, but it took long time for me to make it work.
Points to consider
a. After flashing my phone didn’t boot. I just flashed only the recovery, I think that would caused the problem, later I re-flashed the stock rom boot img separately).worked !
b. Instead of backup copy I tried with the stock rom imgs, It worked for me. If you don’t want to lose any data please use your phone backup copy img files.
c. I am not a developer & don’t know how the stuffs work inside the mobile, with the help of XDA contributors & developers forum messages, I was able to do something.
d. Please do read the rooting & flashing guides thoroughly.
e. Please don’t panic if something goes wrong. Stock rom is available, flash it & you get your mobile back.
ROOTING & BACK UP
1.Frama root will give you the root rights ! - http://forum.xda-developers.com/showthread.php?t=2130276
Download & Install - open it choose install super user, then click "boromir" success message will appear, click ok and reboot your phone. You can see a message "android is updating" after you reboot your phone.
2. Dowload MTKdroid lastest version (older version also fine)-sorry I couldn’t find any working links
Backup your stock rom using MTK droid tool, before making any changes to the stock OS. MTK droid tool may ask you to root again. Please read rooting and flashing instructions thoroughly before doing any changes.
a. Install MTKdroid tool in your pc & open it, If the tool asks you to root, click root, in couple sec or mins yellow signal will turn green.
b. Click on the “Root,backup,recovery & then click backup – Please wait till the process completes
If the message says “end with error” – The backup copy will not help us to re-flash the OS
(I tried many times, but I am not able to flash the backup copy with SP flash tool, gives me some error.
(for making CWM the above copy is fine, because I hope there won’t be any error when the software creates a backup for boot.img & recovery.img)
c. Ok assuming that there is no error, the next step is Click on the button “To prepare blocks for Flash tool” – wait till it completes. This process will gives us the entire copy of the rom to flash it with SP flash tool – Can find the backups in MTKdroid tools /backups/ Karbonn-A2+_number _date_backup_ folder/file to flash tool. (MTKdroid tool is required to create CWM, so don’t close the MTKdroid tool)
d. No stock roms were available when I was testing that time, so I ended up with the service center. Thanks to XDA member “Forever Alone”. Now working stock rom is available.
3.CWM CREATING & PORTING
a. Select “To choose the boot.img file & click recovery & boot. Software will ask you to select the boot.img. Select the boot.img from the backup copy in MTKdroid tools /backups/Karbonn-A2+_ _backup_ /file to flash tool.
b. Click Yes - To make CWM automaticllay
C. Click yes - If phone isn't loaded, it is ness to flash this file...to phone? Software may show a write error, just leave it for now.
e. Click NO - Install created recovery to phone ?
Copy of the recovery & boot img will be in MTKdroid tools /recovery
Now CWM has been created & that needs to flashed via SP flash tool
4. Flashing CWM recovery
Download SP flashtool - http://forum.xda-developers.com/showthread.php?t=1982576
Copy the scatter file from Mtkdroid backup folder to mtkdroid recovery folder to avoid confusion in selecting the image files.
Open SP flashtool – Select the scatter file from mtkdroid recovery folder & flash it. You are done. Now you can see the auto made CWM instead of stock recovery
attachment has screen shots-please refere that to this section
5.Download the stock rom from - http://forum.xda-developers.com/showthread.php?t=2520719
Extract the files & store it in separate folder.

Root Moto G google play edition on Android 5.0.1 Lollipop

First u to download the Philz touch recovery for GPE device, then you have to flash it using ADB and don't forget to backup your stock recovery.
Then download the SuperSU.zip v2.37 by chainfire as it supports root for all Lollipop devices, then flash it using the custom recovery you downloaded and flashed to your mobile and it successfully flashed and your device will get rooted....
Happy flashing and rooted the lollipop device......
Here is the recovery download link

There are many threads have info on how to root.. why did you started the thread in development section.. did you developed anything? Reported to mods for moving this thread to General section...
It is especially for people who are suffering to root on moto g gpe device after lollipop update.
So i think it will be helpful to them.

It gives the full root to the device but the thing is that , some root apps are not fully supporting in lollipop devices and think they will give full support in future updates....

I am a new user of Xiaomi Mi 4i Indian version. I am on MIUI v 7.2.3.0 with no root and so no TWRP installed.

And what i have to do if something goes wrong during downgrading process. plz help me..... i don't want to my phone bricked.
Download previous version and just flash it using stock recovery or just go to updater and select update zip and let it flash
It is official way to do it manually. Without any root or twrp
And don't worry xiaomi gives warranty even on rooting device

thanx for replying.dude... i know the TWRP process. It has backup and restore option. But rooting v 7.2.3.0 Is little bit hard(have to use pc). I just want to know if there any process for backup and restoring process without root as i want to downgrade without root and i dont want to go service centre.... thank u
When flashing MIUI, it is recommended to flash it via stock recovery as if you flash it with Custom Recovery (TWRP), it will output errors and flashing won't succeed. If you want a clean start, I suggest flashing via fastboot.
Thus, download desired version of MIUI, and flash it via stock recovery itself.

No, you can't flash any zips without custom recovery or root.
You'll have to build a recovery for your device based on the series of MTK CPU you have.
There are guides all over the internet for building or porting recovery for MTK devices.
