I have a Dapeng A7 mtk6573 Android phone I just purchased. It was supposed to come prerooted but for some reason it did not and the ebay seller wont take it back or exchange it with another one that is rooted like the original item description said he would. So Im not sure where to go from here. I tried Superoneclick and didnt get very far with it. I am still new to the whole rooting process but i managed to root and rom my Evo 4g without bricking it multiple times. I can follow any directions given just need some help to be pointed in the right direction on how to get this one rooted. Can anyone help?
hi, sorry fo my english
you must download a russian modded recovery here: ge.tt/5UwovRF/v/02
you must flash it with flash tool,...(see many guide in internet if you no know)
after you must enter in it, you pull power and vol+ together,
and install this file: ge.tt/1ili71F/v/0
after you had disabled verification of signature.
so reboot your phone

As soon as I have some spare time I'll try to follow this

But the SuperOneClick download is detected as virus, so I have downloaded it from xda-developers

SuperOneClick does not work on my Dapeng A7. Instead I use adb remount, then adb push superuser.apk into /system/app. This works.
Please note that adb remount does not always work. I have to try a few times. Most of the time, I got success by turning USB debugging on only after I connected the phone and umount USB drive.
Dapeng A7 1gb rom custom recovery
I have good news for 1gb Dapeng A7device owner (aka e1108_v73_hjy2a7) who wants to root/backup their phone.
I just finished modding a custom recovery based on 512mb recovery by replacing original boot.img with 1gb boot.img and tested to work fine (credit to linerty for the base of 592zn.com recovery image file)
To use this, please make sure you have 1gb rom via engineer mode by typing *#*#3646633#*#* on dialpad and choose Memory > Nand Flash ... if it states
Name : KBY00U00VA_B4, ID: 0xecb3, total size 1024mb
Click to expand...
Click to collapse
then this recovery is for you.
Using 512mb recovery on 1gb device will show below error due to missing partition when boot into recovery:
E:can't mount CACHE:recovery/command
E:can't find MISC:
E:can't mount CACHE:recovery/log
E:can't open CACHE:recovery/log
E:can't find MISC:

here is Dapeng A7 1gb custom recovery:
http://www.4shared.com/archive/83g2LqtZ/dapeng_a7_1g_rec.html
Dapeng A7 1gb scatter file: http://www.4shared.com/office/XWtNUNVL/MT6573_Android_scatter_dapeng_.html
make sure you download both files
Use SP flash tool, load the scatter file, make sure you only tick recovery and choose the img file ... remove battery and usb cable, press download on SP flash tool ... insert battery .. then insert usb cable (you have 15 sec to do this) ... once it finish, remove and reinsert battery, hold Vol up + power to boot into recovery
-------- after booting into the custom recovery -----------
Now you can flash the uniroot2.signed.zip to root it (get it here) or make nandroid backup, flash custom zip etc. (to flash custom zip - eg: custom rom, make sure toggle signature verification to disable 1st)
512mb device (e1108_v73_hjy1) please use the custom recovery as stated here.
Note : It is advisable to make a full factory backup using mobileuncle gscript after rooting your device as stated here : http://forum.xda-developers.com/showthread.php?p=27039072
Disclaimer: please understand that I'm just trying to help and do not take any responsibilities if you brick your device. (mt6573 devices won't easily brick if you have your backup or the right factory firmware - simply run SP flash tool and overwrite for factory firmware or use recovery mode to restore backup)
ps : recovery mode is good until you mistakenly flash preloader/dsp_bl/uboot img file .. other than these 3 files, the phone should be up and working after restore.
Problems with our two DAPENG A7 and mobiles-phones.cn
Problems with our two DAPENG A7
Hello,
(sorry for my english, it's not my first language)
We bought two Dapeng A7 from mobiles-phones.cn last month. both of them failed within a month !! The first one had video bugs and could not take phtos and videos anymore (cost 26€ to return it back)
The second one has no more microphone and needs an earphone to work !!
A friend of mine just received the DAPENG A75 last week and has a flash LED problem.
So, take care with these Dapeng products wich are not reliable (we had a chinese H7300 wich was very good) at all. Don't hesitate talking about chinese phones troubles on this forum, it could be good for someone hesitating to order over there.

DAPENG A7 = MT6573
DAPENG A75 = MT6575
Please do not mix between the models. Btw, have you tried restore to factory/factory reset? maybe it's only a software bug.
Dapeng A7 1gb firmware backup
Hi all,
After going through much trouble .. I finally managed to extract Dapeng A7 1gb rom (e1108_v73_hjy2a7) in the form of img files so that others can try revive their bricked Dapeng A7 1gb phone via spflashtool.
Take note that this is only for Dapeng A7 1gb nand/rom ONLY. Please check via dialpad *#*#3646633#*#* and choose Memory > Nand Flash.
http://www.4shared.com/archive/n3y60_1L/backup_dapengA7_e1108_v73_hjy2.html
This is unrooted, untouched firmware. So if you want root, refer to my previous post on how to root using custom recovery and uniroot2signed.zip
Now I don't have the phone anymore. So I wish all the best to those who wants to revive their phone due to wrong flashing/etc.

Hello Friends
Sorry for my bad English, I use google translator
I have the Caterpillar CAT B15Q dual sim
Processor: Media Tek, MT6582M QUAD CORE 1.3Ghz
Android 4.4.2 KitKat
ROM Flash: 4 GB
RAM: 1 GB
Extended Storage: Micro SD Up to 32 GB
I have make ROOT with Kingo Android Root - everything worked very well untilwhen i have unwittingly deleted white sim card icon with small circle gear.
Unfortunately, I have not done before any backup.
First smartphone stops responding so I turned him off ... after restarting appears only the logo CATB15Q welcome ...
and that's all. Hangs on the splash logo.
When I press the POWER button and the VOL + appears in the Android system recovery <3e>
After taking a wipe data / factory reset the phone sometimes handled exclusively but not functioning properly. Is seen by the computer.
Is it possible to somehow fix it? Are possible going to work support 2 SIM cards ? Is it possible to upload to it was something else, for example Android version 4.3. ?
Would someone please upload a cwn backup or a link for b15q rom, or B15Q_GENE_DS_1.019.000 because its nowhere to find
This is my first android phone
I don't really know what to do next ...
For all the help I would be very grateful

Update __
RK3188 adb is running no screen__help PLEASE
After erasing IDB in my unknown china tablet and loosing my whole system I was able to load different custom firmware from Chuwi v88 + different kernel and my Tab popup in windows showing 2 extra drives F and G.I did open android studio and notice access to adb and all activity in my android.The RKandroidTool also recognizing my tab.
No reaction to power button only automatically connecting to my comp ( black screen on my tab).
I have original CWM backup of my device.
Can someone advise me how to access recovery from this point or find the way to completely start my tablet.Maybe is possible to recover CWM from adb?I will need some help to use a proper commands perhaps in adb.
