[FAQ][REF] Korean Motoroi XT720 Updating, Root, OC etc..

well, not exactly a FAQ...
I write this as a user of a Korean Motoroi XT720, in Korea. I do not know or care much about using this phone elsewhere, but some things here may still be useful for people in that situation.
First the Korean version Motoroi XT720 is not exactly identical to the international Milestone XT720 and certainly not identical to the original Milestone A853 (Thanks to Mioze7Ae for pointing out about the original.. also see his comments in next post about more detail on the subject.)
For one it has DMB, the internal storage apparently varies on other versions (I think), radio frequencies and APN settings are not compatible if using ROMS from the wrong device.
It may be possible to make a ROM from another version work, but that's not my thing.
Roms from for the non-Korean versions probably will not work without some changes
And therefore, custom ROMs from English sites probably don't work. There are android developers in Korea, but I don't know if any develop for this phone.
Updating
repeating:
Roms from for the non-Korean Milestone XT720 probably will not work without some changes
And therefore, custom ROMs from English sites probably don't work. There are developers in Korea, but I don't know about this phone.
Froyo (android 2.2) gives you apps 2 sd.. which you need if you have many apps.
Froyo update linked from first post of this thread:
http://forum.xda-developers.com/showthread.php?t=881801
Don't worry about the bugs reported there if you are using the Korean model. The bugs (except for maybe the mediaserver issue, more later) are related to the fact that people are using the rom on non-Korean phones.
The rom there is the same rom as available officially on the Korean update site. It's just much easier to get it from the above link.
To flash it,
1)get any version of RSD-lite (I used 4.9 and it worked). I used windows xp to run it. Mileage may vary with windows 7.
2) Run it. Load the sbf file.
3) Check that the file stats get filled in (otherwise you got a bad download which happened to me once).
4) Put your device in download mode (keep reading for instructions).
5) Connect the USB.. use a good heavy gauge cable like the stock cable, and plug into a rear connection on the computer. This really can matter.
6) Hit start, and wait a long time, this phone's flash process is REALLY slow. (compared to Samsung)
Within a couple of minutes though it should be clear that something is flashing and progress indicators should be incrementing. Don't wait hours.
There's a good youtube video somewhere for the milestone.
**Official Update
Unlike the manual suggests, OTA does nothing.
The latest official ROM version seems to be reported here:
http://www.mymotorola.co.kr/product/PrdRsdPhoneList.aspx
So in the unlikely(?) event there's another significant update, we should see it there.
Official updates are flashed by a web app from here:
http://www.mymotorola.co.kr/product/PrdRsdMain.aspx
A thread discussion roughly how to traverse that complicated Korean web page process to do the update is here:
http://forum.xda-developers.com/showthread.php?t=908314
Notice the non-Koreans failed, but that's because they had the wrong phone. Your phone should be connected by USB when you start the web process. It took me two tries and a computer reboot to get it to work, but it worked. It probably helped that I can read most computer terms in Korean writing.
**Download and Recover Modes
Download mode allows ROM flashing. Recovery allows wiping data cache, and applying update.zip files (which can modify your rom).
Download and recovery modes keys
Recovery (mostly quoted from someone else):
Turn off phone
Press Power key + Camera Mode Key to power on the phone and bring up the recovery screen
(Trianlge with exclamation mark shows after motorola logo)
Press Volume Up + Camera Key to show the recovery menu.
Use Volume Up/Down Key to highlight and Camera Mode Key to select
Be careful.. selecting wipe data, will obviously delete most of your apps.
Download Mode:
Turn off phone
Press Power key + Volume Down + Camera key
Camera mode key is the little one next to the cammera key.
Volume up means the one toward the top of the phone.
If the battery is out of the phone and if it turns on when you put it in... then replace "power button" above with "insert battery". You don't have to contort to do both as some people say. Either way, the power key or battery should be the last part of the combination.
**Rooting
Super one click is said to work, and certainly it should. I used the rageagainstthecage exploit with adb (the same exploit as super one click). There's a similar hack described elsewhere here. I can try to improve this section if needed later.
**Market Games etc
Many applications are blocked to Koreans in the market. This includes all games. Use the Market Enabler app from the market to fix this. I use it to set my provider to [us]T-mobile. If you get the pro version it can be made permanent on boot up. The free version isn't.
**Some Tweaks and tips
Launcher
The stock launcher is a little jerky on this thing, or was in eclair, (update.. I think froyo and/or the mediaserver fix solved this)
Anyway.. you can try ADW launcher or launcher pro or something else if you have problems. These sometimes pause to reload though when you hit the home key.
mediaserver bugginess
A few people using the Korean froyo on the Milestone report that there is a mediaserver issue where mediaserver consumes battery and slows the phone. I may have detected this on the Korean phone too, but not sure yet (not pateint enough). The solution offered around here is to replace the media server binary. Here's the link I found for a new one:
http://dateno1.egloos.com/28452
It is a Korean page, so it probably is an issue for the korean phone. I installed the mediaserver_d file, and the phone still works and yes, maybe better, but if you do the fix incorrectly, you can boot loop your phone and need a reflash. I don't know the difference between the two files offered there.
so the way to do this (assumes basic knowledge of adb use)
1)root the phone
2) cd to the directory with the mediasver_d file
4) do all this...(this has not been cut and paste tested, but it's what I did by hand, check for typos).
Code:
adb pull /system/bin/mediaserver mediaserver.original
adb push mediaserver_d /data/local/tmp/mediaserver
adb shell
$ su
# mount -o remount,rw -t yaffs2 /dev/block/yomama /system
# mount -o remount,rw -t roots / /
(the mount type and device name actually don't matter for a remount command)
# rm /system/bin/mediaserver
# cat /data/local/tmp/mediaserver > /system/bin/mediaserver
# chmod 755 /system/bin/mediaserver
# reboot
Keyboards:
If you want Korean and English entry, and want spell checking in English and an overall much better keyboard, I highly recommend Smart keyboard Pro, and download the English and Korean language packs for it. I've tried many keyboards. Keep in mind though, I don't like swipe. Don't forget to configure the spell checking stuff. You must enable it in settings and you must select it as your input method... long press on an input box.
Lockscreen
If you don't use pattern lock, skip this. If you use pattern locks you probably see no need to 1) press power 2) do a slide lock 3) do a pattern lock. On many phones the pattern lock disables the slide lock. On some, including this one, it sadly doesn't. The only unlocker toggle I found that fixes this is Anti Lock from the market. It uses a little battery and it flashes between screens real fast in an un-appealing way for half a second when you press power, but it gets it done. I like having it better than not having it.
Tethering
There's a 3G hotspot app included for this.
**Overclocking:
This device is potentially very overclockable/underspecced. (but don't take my word for it, I only know rumors and such.. do this AT YOUR OWN RISK This may damage your phone (if you overdo it) and you may be denied warranty repair.. real examples of this exist I think(questionable source)
First root the phone.
Get Milestone Over-clock. You must find version 1.4.2. On the web site you must click show all versions or something like that on the download page. Newer versions don't work on the Korean device.
Run it. Slide the slider all the way to the right to get custom mode (you really should use custom mode) Hit menu key. GO to settings. Do *NOT* check apply on reboot until you've tested your setting. There's a thread around here, I'll link too soon, with people's experiences. On my particular device I cannot get as a high a speed with as low a "vsel" (chip voltage I think). I run about 4 vsel higher or more to stay stable for long times during angry birds.
I found that 1 Ghz, at 60 vsel (most people run 1Ghz at 56 I think) rebooted my phone after half an hour of heavy use, and became pretty warm. I backed off to 900 Mhz at 58. I think this is ok for me. I may just be unlucky.. chip variation does exist, or maybe the Korean models are a little different (see Mioze7Ae useful comments in next post).
**A little about ROM file manipulation
This is just here to point the curious in the right directions. I have not explored this stuff much yet and some info may even be wrong.
Anyway, this is just a FAQ not a development thread.
Again custom ROMs from English sites made for Milestone devices won't work without some changes.
Kernels are locked by the boot loader (at least that's true for the Milestone), so no custom kernels exist (well not in a very practical sense).
Official Rom files are SBF files. SBF files are packed together smg files.
SMG files are apparently yaffs2 image files and can be mounted with loop mounts on a linux system or the phone.
update:
So actually you need yaffs2 support and you need to create a nandsim device on a ramdisk, so that's a bit involved:
http://www.aleph1.co.uk/pipermail/yaffs/2005q3/001356.html
and it seems you can probably dd the image file onto the ramdisk then, or unyaffs it.
but in the end that should allow actually editing the image, and possibly even producing modified flashable images.
but unyaffs works to extract the contents of CG39 (/system) and CG33 (/cdrom.. whatever that's for).:
http://code.google.com/p/unyaffs/downloads/list
You can google a windows version too.
MotoAndroidDepacker or sbf-recalc are two tools that can unpack sbf files to smg files and repack them again (possibly even making modified flashable ROMs). sbf recalc has a linux version but I only found a binary which dynamically links to the wrong versions of libstdc++ for my system.
It seems more popular around here to create "nandroid" images (which I think are also just filesystem images, but I haven't really played with it).
Open-recovery seems to be the tool of choice for making and flashing nandroid backups, but I haven't looked into this at all yet.

Nice!
About overclocking--be aware that according to paper specs Motoroi XT720 and Milestone XT720 have different CPUs. Supposedly, the chip in Milestone XT720 is rated for higher clock rates (800 vs 550 according to TI iirc, but Motorola put it to 720 to be cute, I guess). It has been claimed that it's actually the same die and manufacturing process but TI sold the chip slower initially. Motoroi has the same CPU as A853, iirc.
There are some korean ROMs. We don't know a lot about them here unfortunately due to language barriers. Another phone very similar to the XT720s is the XT701 sold in China. It has an exploitable bootloader.
From what we've been able to figure out the biggest differences are the TV tuner and the sensors. Things got really confused over here (XDA) because the froyo ROM we had was based mostly on A853's froyo (Dexter's ROM). Lately were working on a ROM that's mostly based on the Korean froyo. The file differences between the two are much fewer.
For now, the most important part seems to be running the right kernel because sensors don't work correctly when you're running the wrong one. The partition tables are baked into the kernel, so the Motoroi has a partition table better suited to froyo. The total internal memory is the same, but the Motoroi sbf has a larger /data and smaller /cache and /system.

Good info. I don't know these days, but years ago chips with different speed was largely the result of random variation and QC checks. If they sold it slower originally, then slower chips may have gotten through QC. I don't know if that logic still applies much anymore. I heard that many many years ago.

oops this post was in wrong thread somehow..

I have a Korean Motorola Milestone phone. I unlocked it in Korea & brought it to Europe to use. I did 'factory reset' and it worked fine. I had to 'root it' to install some special fonts. The rooting was successful and I was installing the font during that time the phone reboot itself and stuck at the first 'T' screen (Korean vendor). I tried to re install it to factory default but of no use. The problem persists.
At system recovery level I get four options:
1. reboot system now (tried & failed as the system is corrupt anyway)
2. apply sdcard:update.zip (I can't do as I don't have an update.zip)
3. wipe data/factory reset (yes I did this but still no recovery as the
default system is presumably corrupt)
4. wipe cache partition (yes, I did of no additional use)
with this background I wonder whether there is a way to recover my phone using SD card?
[ps. on two occasions the phone suddenly worked but I could never connect it to wireless network as the Input Keyboard did not work. Hence I could not connect it to Android application market (btw. the basic applications are still intact). Thus the possible way out is to recover it externally using my PC (if my phone allows me to connect it via USB or through micro SD card with system recovery console]
Any help?

[ROM]DocHoppyRom NEXTBOOK 7 Premium*updated DocHoppyRom Full On Rootv2.0*2/14/2012

I was working on a ICS based hoppy rom. Unfortunately I just had a catastrophic screen failure, apparently when my laptop bag fell last night, it landed with enough force to shatter the screen on my nextbook! Oh well. it may be a while before I can work on anything to further the version I was working on.
FYI- Due to work, my time is very limited for working on the next version of Hoppy Rom. I apologize in advance. The company I work for is
setting up new engine test cells in China, and my self and 2 other people are main points of support! again Sorry for anything new taking so long!
DOCHOPPY HAS BEEN SIGHTED (Other than on a DAYZ server...Stay tuned.
Ok I have decided to pass along what I have been working on.
Warning***
This is for the Nextbook 7 premium ONLY!

CRAMFS STYLE 3.0
AND
FULL ON ROOT v2.0
Disclaimer: I am not responsible for Bricked Tablets. This is known to work on tablet with SN starting with YF1011, and some YF1211.
First you will need to decide which version of the Rom you are going to load. The CRAMFS Style version has SU but you CANNOT write to the /system directory. This is a good all around Rom for those who may need SU but do not need to write to /system.
Full On Root is just that, you have full read write to the /system and can customize the Rom to your hreats content.
HOW TO INSTALL:
TO FLASH CRAMFS STYLE 3.0 Put the UPDATE.IMG file from the Cramfstyle Folder onto your SD card, while tablet is on and follow the on screen instructions.
After running the self extracting Zip file you will have a directory containing the following folders and files.
Drivers (folder)
CramfsStyle(folder)
FullonRoot(folder)
Log(folder)
Language(folder)
Readmefirst.txt
Rkusb.log
RkusbComm.dll
Setting.ini
RK29update.exe
TO FLASH CRAMFS STYLE 3.0 Put the UPDATE.IMG file from the Cramfstyle Folder onto your SD card, while tablet is on and follow the on screen instructions.
To flash Full On ROOT, Plug your nextbook into your PC via usb cable. Turn your nextbook over and with a safety pin or something of similar size, press and hold the reset button for 2 to 3 seconds.
Run the RK29update.exe
Select your Rom files via the boxes containing the .... And navigate to the correct directory for the rom you want to install.
Insert eache file in order according to the update tool.
Clear IDB. (this is like a lowlevel format for the Rom tool:
After the Tool says OK. Select Run. This will begin to load the Rom onto your tablet. It will go through loading and then checking the Rom install.
After the Rom loads and the tool comes back with an OK, patiently wait for the tablet to reboot, and load the new ROM. If the tablet is still connected to the pc via USB when the rom boots it will show the screen allowing you to select weather or not to turn on USB storage. Press the home key and you will be given a choice of Golauncher or Rklauncher. (go lock is a screen lock program.)
Enjoy the Rom!
Disclaimer: I am not responsible for Bricked Tablets. This is known to work on tablet with SN starting with YF1011, and some YF1211.
Features for both Roms:
Complete and correctly working market. It now correctly associates the tablet to your gmail account allowing purchases from market.
Launcher 3.0 as well as Go launcher ex. Launcher 3.0 was pulled from an rk2918 firmware3.0 update and put into this rom.
Google Calendar is now back and working correctly.
Original Email is back and working correctly.
Included Kindle App
Included Estrongs file explorer.
Both have SU though the Cramfs version cannot write to SW.
Removed Apps Added in last release and return to more of a original rom state.
Rom is pretty clean. And seems speedy.
Cramfs Style 3.0 Rom has 200mb internal Ram +/-
Full On Root 2.0 has 894MB of Free Internal Ram.
Cheers!

So freaking sweet, great work on RW!

I used Wendal's tool to decompress the cramfs file system.
As for the /system, Because the device uses cramfs, and based on everything I have read, using Wendal's tool to decompress the file system, make the changes, and compress is the only way I can see to be able to
customize the rom for the device. The image is rooted, but after the update.img is compressed, the /system file remains read only. I tested this using root explorer, but anything requiring su works fine. But all hope may not be lost, I was reading on a chumby forum someone suggested using mkfs.jffs to make it writable, but further down it notes that you would need to change the kernel (easy enough to recompile I think), to utilize a different file system. The boot loader would also need to be modified, something I am not ready to try and tackle just yet, I think I would be bricking my nextbook pretty quickly.
It is a start and I am actually learning a lot as I go.
Any thoughts or suggestions are welcome.

I am definitely a long time user / cyanogenmod / aosp fan, but as far as ripping open .img files its definitely new territory, I tried to find an internal SD card like the nook has, to maybe dump it, but I cannot find such a beast. Any progress you make is awesome. So do things like root explorer work, just not on /system due to cramfs?

Correct, root explorer does work, but due to cramfs, it does not allow you to toggle to rw from ro on the /system.
Working on taking apart apk's and customizing and rebuilding and resigning next.

just flashed this rom and it works great!
How would I go about doing a custom boot animation or image?
... even if it means flashing a new rom from clean?

This is great. Thanks. The only question I have is why do I see so few items in Market? Does it have anyhting to do with compatability?

Calendar & Sync Access
First, thank you for your work.
Before I update by Next7P, have you included Google Calendar and Sync access in this update?
I use MyPhoneExplorer and will need calendar sync to work so I can fully use for business.
Thanks.
There is another method to get Google Market on the Next7P, I am a new user so I can not post the link, but google , forums Whirlpool net au archive 1756859
, very easy and works great, but cannot get sync to work.
Dan,

Thanks for the responses!
sgtfoo : You can use Wendal's rk29xx tool to take a copy of my rom image, or the original update downloadable from nextbookusa.com, and
unpack it. You then have access to the system directory in an editable format. you can go into the system folder /system/media and replace the bootanimation.zip file with another one. Just be sure the image format is 480x 800 and that the zip file has 0% compression ratio. After you make the changes, just repack .img file via Wendal's tool and reflash.
dodoclub : Not sure why. I have a full market. You might try clearing the data and cache for the market. My market shows pretty full, I.E. I got 31050 entries when I searched for facebook in the market.
Danno65: Actually that is something I have been working on. I can get my google calendar to sync, currently I am using a calendar from the market called Jorte, which works great, how ever, googles actual calendar.apk closes unexpectedly, I am thinking it is just a version problem with the calendar, but haven't had a lot of time to follow up on it.
FYI here is the link to Wendal's tool, which makes it much easier to work on the update.img file.

If you have any request or questions please feel free to ask, I will help anyway I can.

Thanks Dochoppy
Got one of these tablets for Christmass to replace an old broken tablet I use for work.
Google hosts our work email, so I still need to get Contacts and Appointments going, but I maybe able to side load them.
Noticed build.prop still has ro.secure=1. This prevents adb from having root access??

Calendar & Sync Access
DocHoppy,
I came across a post where the "Calendar.apk" and "CalendarProvider.apk" files must be in the "system/app" directory to work properly, I tried to copy these files to the above directory but found it to be read/only, will wendalls tool have to be used to get access to the directory?
Also, did you get your google calendars on your desktop to sync with Jorte on the Next7P, I tried but no luck.
Thanks
Dan
The updated image file worked great, thanks again

Thank you so much for your work in building a new rom for this thing. I am anxiously awaiting a new filesystem so we can have true root. How do we manage to recompile the kernel for ext4 support and change the /system fs?

Hello, first of all, thanks for your work!
I am having trouble loading this rom. it says there's an invalid image file in my sd card and if I want to delete.
Now, I don't know if my tablet is a never or older version of what you guys have...
Next7p
2.3.1
kernel: 2.6.32.27
build: v2.0.7.....
my serial is also different from alot..it starts with YF0511
any help or tips?

I would say the serial number would have something to do with it, check on the site for nextbook and see if your serial is in the same *batch* as ours, if the original serial is in a different group, im assuming the hardware may be slightly different? If so, you can always use his method to repack the original with root.

First off I would like to say that I was very pleased when I came across this thread from another one. I haven't flashed this ROM yet, but plan to. Thank you for your work on this as I have been searching the whole internet since I got this thing [4 weeks now] for some sort of custom ROM. It is hard to use this tablet when I have ICS on my Captivate and Vibrant. GB just isn't as cool.
One thing I hope we can work on is root access, so we then can use Titanium Backup. Then we won't have to manually reload everything when new releases come out.
With all that being said, if there is anything I can do to help, I would love to. Like I said, I plan on flashing this probably tomorrow or Tuesday. Thanks again.

For the record, I got titanium backup working fine on this rooted rom. it is capable. You just need to reboot after it restores a backup.

i'm new to android. glad to see rooted rom finally, keep it up!!!
i have a clarification, any improvement in the booting time? my device took 1min30sec (power ON to ready to use, for me, 90sec seem like not fast enough).

Good luck on improving boot time. And besides a tablet is best used when on all the time... try using the suspend state to quickly wake it. We're just starting with the early versions of this rom... give it time to grow.

Build.prop editing
Okay so observation:
Our tablet is not recognized as a "tablet" by the Android market, only and android device.
What prop would I have to edit in order to have us recognized as I tablet. I noticed this when:
I finally managed (through some internet tutorial before this rom) get the market working (the first version, not 3.1+). And when I downloaded apps (I'll use Minecraft Pro as an example) I noticed that the way mine looked and the way the tablet version looked via android market photos and Youtube, ours looks like an enlarged phone version rather than a tablet optimized version. What can I edit to fix this?

Flashed this today... so for it works great. Love the new boot animation. Great work and can not wait for future releases!

One thing that would be great on a future release [not sure if it is possible yet with out r/w], would be a bigger data partition for apps. Moving everything large to the SD is ok, just takes longer to boot those apps. A kernel that would allow voltage control app [like CPU Master] to work also. Just a thought!

6.The phone will restart second time,still the same as first time we did.Then start third time,same as we did in last two times.Click enter then phone was rooted.
7.You will see two more app was installed in your phone that means root phone successfully.
After successfully rooted, it will install root explorer.apk Chinese version which is rather useless for installing Market because it's all in Chinese. Thus, you need to download this "ES File Explorer" in order to put Google Play into the system folder. People who have a problem when installing Google Play by using apk, for example: Error processing purchase [DF-BPA-13]
Here is how to install a new and working Google Play Store:
1. Download "Vending.apk" from the same mediafire folder above.
2. Copy Vending.apk to \system\app\ folder in your phone by using ES File Explorer in root explorer mode with system file mounted.
3. Change permission of Vending.apk to Read/Write for Owner; Read for others (rw-r--r--)
4. Shutdown your phone.
5. Switch on your phone, you will see Google Play Store app, and Enjoy !
*UPDATE 2* Here is a custom firmware ( most of functions are working and rooted ) , all credits to yiminghung and angelobiz, as usual general instruction and faster links are brought to you by zBeYuz
0. How To Flash Haipai Noble I9220 Firmware On YouTube By Angelobiz
1. Before upgrade to this firmware, remember to backup all your apps using My Backup or Titanium Backup so that we can restore those apps later.
Download ADB driver if you have not installed it ( Tested on Windows 7 )
You must have debug usb active in your phone. this driver need for use adb command example for root script or use MTP function.
2. Download firmware + flashing tool + drivers from here: May 7 Firmware With New System.img
OR Only Driver For Haipai I9220: Drivers
3. Unrar the firmware, turn off your phone and take the out battery, then plug the phone into your PC.
4. Install the driver from the firmware folder that you unrar before, then plug out the phone.
5. a) Go to Flashtool folder and run SPMultiPortFlashDownloadProject.exe
b) Choose Factory Database --> Setup data source file: "MTK_DATABASE.mdb"
c) Choose File --> Open download agent file: "MTK_AllInOne_DA.bin"
d) Choose Scatter File: "MT6575_Android_scatter_emmc.txt" in Firmware folder.
e) Choose the figure same as the picture: SmartPhone MPD.jpg, which can be found in Firmware folder.
6. Make sure the phone turned off and the battery was taken out. Click Start All and plug your phone into the PC then wait about 5-10 minutes for the flashing process to finish ( Write OK ! ).
7. After it is done, we are good to change the IMEI. However, before that try to turn on the phone to see whether the phone is working or not.
8. If everything is ok, excepted IMEI was missing, download IMEI Changer Tool from here: IMEI Changer For Mtk6575
9. Unrar, install the program and run SN_STATION, which can be found on your desktop. Follow the instruction in the Chinese manual, but we only need to follow the picture in that manual.
The file "Modem Database" and "AP Database" is in firmware folder. You need to choose exactly the file that you see in the picture.
10. Write down two IMEIs on the back of your phone ( you need to take the battery out to see it ).
11. Again turn off your phone and take the battery out, then plug the phone into your PC, but this time we need to put the battery back in very quickly as soon as we see:
"COM port searching and preloader handshake ok" on SN Writer Log.
11. Wait until "Write Result Indicator" becomes green, then the IMEI has changed successfully.
OR you can try to change your IMEIs by using ZOPO IMEI ( Thanks to colouriste )
1. REMOVE SIM CARD(S) FIRST !
2. Check "Dual Imei"
3. Type in original IMEI #'s 1 & 2 and then
4. Click "Write"
Enjoy the new firmware with GPS working, wifi improved, front camera working, beautiful font and more...

Tips + Tricks:
1. Thanks mikeysteele: "One thing I noticed after installing Set CPU is the kernel defaults to the Performance Governor. This means the CPU is always running at the maximum frequency so that might explain the poor battery life. I changed it to the On Demand governor and my battery life has improved."

FIGHTING !!!

Hi I would like to update some information about this phone,
1. The resolution of the screen is 800x480.
2. The original battery with 2800mAH capacity is so so, normal usage about 1 -2 days. On the battery stated that the cell made in Japan, yet finished in China.
3. The phone comes with the case with Samsung logo on it, together with a screen protector (not really good).
4. Additional infomation:
a) The front camera is on the left hand side, which is quite bad, because the Galaxy Note's is on the right side.
b) 3.5mm audio port is very depth, I have no idea why, so normal headphone or earphone like Beats Monster,for example, will be loose. But we still can use the one comes with the phone.
c) Camera is 8Mp and the picture looks quite nice if there is enough light.
d) It runs very smooth without any issues.
e) There is no touch pen.
f) Android 4.0.3 without Google Play or Market, Youtube, Google Map.
g) The camera sometime has a noise, like tac tac, when the apps need to use it ?!
At the end ? I still like it and I will try to update other good and bad points later if I can find any
*Update on 17/05/12*
h) After a long usage, the phone using original rom sometime can't rotate the screen even the "auto rotate option" was on.
--> Solution: Remove the battery and put in back in 30s, the phone will be functional as normal.

Please share this with us!
I received this same device today. It is not dual core, see: http://dualsim-smartphone.com/img/smartphone/i9220_mtk6575_dualsim_8.jpg
If any vendor claims it is so, what they are referring to is that it has both a 'normal' cpu plus a graphics chip. This is normal and its not the same as dual core!
Neither is the display qHD, as that would be 960x540. This device is 800x480. The display is... mediocre. I don't find the low density to be an issue, but a grainy texture is visible on light areas, e.g. the background in the Messaging app. Colour accuracy is also pretty bad: you get what you pay for.
FWIW I arrived here by googling DF-BPA-13 as I have the same issue. My temporary solution is to load apks onto the microsd on my old phone, then install those through "File Manager"

Thank you, guys. I will update my post above.
Btw, Does anybody hear anything about customised and rooted rom for this phone ?
To richardkemp, can you teach me how to recognize a dual-core phone ?
I thought all the mtk6575 phones were the dual-core phone.
Thanks in advanced.

@zbeyuz: The picture I linked above is from the link you provided in your first post. The first line of the results on the left hand screen shows "Number of cores: 1". Further the vendor correctly lists the chipset as the Mediatek MTK6575. Googling this might bring you (eventually!) to Mediatek's product page for this chipset. You can be sure that if it were actually dual core, the manufacturer would want to tell you about it: they mention no such thing.
Something I noticed while browsing chinese phone websites was that different sellers would provide different specifications for the same devices. Some would claim that a chip was dual core, by counting the presence of a separate main processor and graphics processor as if it was 'dual core'), and some would claim higher chip speed, e.g. 1GHz main processor + 500mhz graphics processor = 1.5GHz total. This is misleading and nothing more than a sales tactic.
It's a shame there's so much misinformation, the vendor I purchased my Haipad from marketed it as having an AMOLED screen, which it plainly doesn't.
As for ROMs, I'm gonna get stuck in to some ROM cooking once my exams are over, but that won't be for another month. In the mean time, I sure would appreciate any tips on getting root. To save anyone checking, SuperOneClick doesn't work.

Additional info on the device:
- Screen is capable of detecting 5 simultaneous multitouch points
- (In the UK at least) Network location does not work. Google maps cannot find my location from cell towers, or from my Wifi. GPS does work however.
- My device came without Android market installed, and as mentioned above, does not work once it is installed.
- Either the proximity sensor or the light sensor (top left by the front camera) flashes faint red constantly when the screen is on. Not a big issue but slightly distracting. The values reported by the prox sensor are just 0 and 1, no middle ground.
- The light sensor reports only 3 light levels: 160, 1200 and 2600. This makes automatic backlight pretty rubbish.
- The speed of the phone is fine - I will add some benchmarks later. Right now it's a pain in the butt since I can't get the benchmark apps from the market.
- WiFi signal seems weaker than I'm used to - my reference devices are my desktop PC, my Fujitsu ST5112 Win7 tablet, my (retired) HTC Desire, and my girl's Samsung Galaxy Y Pro and Asus Win7 Ultrabook. These all received moderate to good WiFi signal in my room from my WNDR3700 N router, all capable of streaming video at this distance. The Haipad on the other hand shows weak signal in the notification bar, and subjectively it is much slower than when it is downstairs nearer the router, a bit of a disappointment here.
- Lots of info on the device is available by starting the "EngineerMode" activity belonging to the "EngineerMode" package. This can be done by making a homescreen shortcut with a third party launcher (eg Nova), and choosing to add an activity shortcut. I recommend only look, don't modify any settings in case you break something!
- I don't know if it's just me but I find the overscroll elasticity way too 'loose'. If I flick a list hard and it hits the end, it takes a long time for the list to settle into the correct position. I look forward to being able to tweak this...
- The battery seems to charge quite slowly. I know it's large so getting to full charge would take longer than with a standard battery, but I am used to large batteies - I used a 2200mAh battery in my HTC Desire and I'm pretty sure it charged faster (using the same charger). Of course a factor in this will be that I have had the device active with the screen on almost constantly, so a lot of power is being diverted to that.
- My phone is capable of connecting to my network (t-mobile)'s proper 3G service, but seems to sometimes choose a 2G service instead, even when there is just as good 3G signal.
Will update this with more as I think of them.
zbeyuz, you say your camera is on the left, I presume you mean the front camera? the main/rear camera is right in the middle.

@richardkemp: Thank you for your quick reply. I did mean the camera in the front is on the left. The main camera is right in the middle, yes.
However, last time, when I tried to put on the Galaxy Note's case, the main camera didn't fit in the right position of the case. Maybe, because the screen was bigger than the real Galaxy Note's, I think ?
Update: The default browser of phone ran quite fast even there was a low wireless signal, but the browser didn't have back and forward button, is that right ?

This is from my seller and it works.
1.Please download root file on
www.t-kstore.com/4.0root.rar
2.Go to*setting-developer options-click USB debugging
3.Connect the phone with computer,turn on usb device.
4.Click the file you download from the link TPSparkyRoot.bat*
5.Your phone will restart first time,after the phone start finish(until you see the unlock),click enter in the window of TPSparkyRoot.bat.
6.The phone will restart second time,still the same as first time we did.Then start third time,same as we did in last two*times.Click enter,then phone was rooted.
7.You will see two more app was installed in your phone,that mean root phone successfully.
After successfully rooted, it will install rootexplorer.apk Chinese version which is rather useless for installing Market because it's all in Chinese. You should be able to find Filexpert.apk from the web, and install it.
Here is how to install Google Play Store:
1. Download Vending.apk from http://downloads.androidadvices.com/apks/Vending.3.3.12.apk
2. copy Vending.apk to \system\app\ folder in your phone by using Filexpert in RW mode
3. change permission of Vending.apk file to Read/Write for Owner; Read for others
4. shutdown your phone.
5. switch on your phone, you will see Google Play Store app, and enjoy!

Did anyone mange to get GPS working ? I tried with Google Maps, but fail.

Thanks a bunch bthoven. I took the liberty of tidying up the script a bit, and including the latest Google Play Store and an English root file manager (Filexpert, as you suggested).
I put it on mediafire: http://www.mediafire.com/?qnmvebaa3k8usjw
Same instructions as before, just extract the archive and run TPSparkyRoot.bat with your phone connected by usb cable, and USB debugging mode enabled. If you wish you can disable USB debugging mode once this process is done.
Beware that the play store I included is the mod version from http://forum.xda-developers.com/showthread.php?t=1582422, to allow you to access apps without region restrictions. In future we can properly set the phone's region in build.prop should remove the need for this temporary fix. That's for another day..

[ROM] Custom Rom For ChaCha - GB

Hello everyone!
Finally, I am satisfied with my chacha. I was constantly shifting between stock custom rom and cm roms. In stock rom everything works but automatic backlight settings are just terrible (especially dim threshold and keyboard light settings) and status bar is bigger than in cm roms (32px vs 25px). Cm roms have all of this but there are other things that still need improvement (front cam, some stability issues etc.). Therefore I decided to create my own mod of stock rom. It is based on Europe RUU 1.3.3 android 2.3.3. I couldn’t find anywhere 2.3.5 Europe rom but to be honest I don’t see any difference between the two. There are two versions:
1. Full sense rom: Link
What is different: rooted, added busybox, support init.d, dta2sd included (you need to partition your sd to ext2 or ext3 after installation and enter dta2sd commands from terminal emulator – google for the commands if you don’t know them), changed the ugly calculator app, added file explorer, added latest play store, Flash player 11 is working. I haven’t removed any apps because in this version I wanted to leave that to the user according to his/her own preferences. Status bar is smaller (more space on the screen) and I themed it a little, removed charging icon (I know that it is charging because phone’s led is orange ). Automatic brightness is tweaked (added lower brightness level, lowered the max brightness of the f button, and added one level for the keyboard lights (sometimes, in stock roms, I couldn’t see my keyboard clearly and the damn lights just wouldn’t turn on so I had to do this tweak as well). And rom is fully deodexed.
2. Stripped rom (no sense): Link
What is different: rooted, added busybox, support init.d, dta2sd included (you need to partition your sd to ext2 or ext3 after installation and enter dta2sd commands from terminal emulator – google for the commands if you don’t know them), changed the ugly calculator app, added file explorer, added latest play store, removed sense, added widget locker, holo launcher, removed a lot of bloatware (at least, bloatware for me), f button is not assigned (I’ll leave that to the user, I use it to turn my screen off but didn’t changed it to this since several people reported issues). Same automatic backlight and status bar tweaks like in the sense rom and it is also deodexed.
3. Stripped rom (odexed): Link
What is different: Same as in stripped rom with the exeption of these: odexed (now 120mb free out of the box), status bar icons have an ICS look and color (wifi, signal, data, bluetooth etc.), notification toggles app added (fully functional and works great, just in the settings set it as an on-going notification and as old in order to be always on top; it has many different icons and styles and colors are changable as well, really nice app), fb button is set to turn screen off, dta2sd not included, different backlight values.
Automatic backlight and status bar tweak for odexed version: Link
Automatic backlight and status bar tweak (sense and stripped deodexed): Link
Flash Player 11: Link
Instructions:
1. Reboot into recovery; wipe data/factory reset; mounts and storage/format system; install from sd card; choose and install your rom; reboot your phone; finish your first boot setup.
2. Reboot into recovery; install from sd card; choose and install backlight.zip; reboot your phone.
3. Install flash player apk; reboot phone.
That’s it. Hope that someone will like it.
Sorry for the poor screenshots.
Regards
P.S. I am not going to support these mods. Everyone is invited to use them and do with them whatever you want. So please don’t ask me does it support this, does it support that, can you do this, can you do that. For me, it is perfect and I don’t need to do or change anything. Everything is working for me. I just wanted to share it with you. I hope that you can understand this.
Edit: I used this guide (thanks kylon) to improve wifi signal range and it worked for me, so I am going to share these settings with you. Mke sure you do this with your WiFi off. Here is what you have to do:
1. Copy your calibration file (found in proc in the root of your phone) to the sd card (it is best to do all steps with root explorer) and download from the attachments framework.jar (here is a link for an odexed version - extract jar and odex files) and symlinkv2.zip.
2. Move the calibration file to system/etc and set permissions as they are set in the screenshot.
3. Reboot into recovery and install symlinkv2.zip.
4. Open calibration file in system/etc (again, best with root explorer) and change this line: rssi_offset=0 into this: rssi_offset=-30
Delete created bak file if you are using root explorer.
5. Copy downloaded framework.jar (I already modified it according to the offset - 30, and if you are using odexed version copy both jar and odex files) to system/framework and set permissions according to the screenshot. Reboot your phone.
6. Done.
This trick did wonders for me and my wifi, hope it will help you as well. If it doesn't, try different values both in calibration file and framework.jar according to the original thread.
Cheers.

Looks noice
Is it faster/smoother than the stock rom? I would go back to the stock rom if it wasn't so hard to configure and it wasn't so damn sluggish compared to CM7/CM9.

Every rom that I use is fast enough for me. Even the unmodified stock. I just wanted to get rid of some apps that are obsolete for me, and I needed to improve backlight settings because when it is night the original settings don't dim the lights enough which really hurts my eyes and I hate that because I have to manually dim. In this rom I don't have that issue. Lights dim automatically.
Although, I found out today that there is an issue with the dta2sd, or maybe the kernel itself. DTa2sd moves my apps and dalvik to sd-ext, clockworkmod creates a backup of sd-ext in a backup folder, and when I restore it my rom just will not mount my sd-ext on boot after that, thus I need to do a fresh install. I would appreciate if someone has an idea why this happened? It is not an issue for me, since I am going to use this rom for a while, but I would like to fix it for the others. When I don't use dta2sd there are no issues. I looked in init.rc in ramdisk, but couldn't find anything unusual. This happened to me with Void rom as well, so I really don't know where to start regarding this.
Regards
Edit: I have been using recovery for a different phone. I just realized this and now, with the proper recovery, everything is restoring fine.

Although, I found out today that there is an issue with the dta2sd, or maybe the kernel itself. DTa2sd moves my apps and dalvik to sd-ext, clockworkmod creates a backup of sd-ext in a backup folder, and when I restore it my rom just will not mount my sd-ext on boot after that, thus I need to do a fresh install. I would appreciate if someone has an idea why this happened? It is not an issue for me, since I am going to use this rom for a while, but I would like to fix it for the others. When I don't use dta2sd there are no issues. I looked in init.rc in ramdisk, but couldn't find anything unusual. This happened to me with Void rom as well, so I really don't know where to start regarding this.

I don't know about data2SD, but I use link2SD, and that works perfectly but with the stock rom, you have to format the sd-ext partition in ext2 rather than ext4, and you can't do it with clockworkmod either, cos it doesn't format it properly :/ you have to use a tool like gparted (if you're a linux user) or some windows/mac equivalent to format it properly

Wow that does look pretty nice.thanks man.

Link2sd works well. Just tested it. Thanks! I don't have the time to look deeper into the issue with dta2sd..

Thank you. In a couple of weeks I will tweak the backlight settings little more, and maybe build a similar 2.3.5 rom (if I find a RUU).
Cheers

Stripped with full stock Facebook Button Functionallity
Great work. This is a solid setup. Thanks for the hard work.
I appreciate that you left the F-Button unassigned for the end user, but is there a way to get back to stock functionallity using your Stripped Rom?
Thank you.

Unzip Stripped Rom, add attached apks to system/app and attached chacha-keypad.kl (unzip the keypad file) to system/usr/keylayout. Zip it and flash it. Let me know if it works.
Cheers.

Thank you so much for the exceptionally quick response. Unfortunately I ran into an error. Let me walk you through what I did.
1. Dowloaded Sripped Rom, and all the files in the previous post.
2. I unzipped the Rom on my desktop
3. I inserted each of the files in their respective folders
4. Zipped the Rom back up
5. Transferred to SD
6. Booted to Recovery mode and tried to flash.
Here is what I got ....
CWM-based Recovery v5.0.2.7
-- Installing: /sdcard/Stripped-Chacha_1-3-3.zip
Finding update package...
Opening update package...
Installing update ...
Installation aborted.

That is weird. I just tested it, and it worked for me. Maybe you zipped it with high compression or sth. Try with normal compression. If that doesn't work, I will upload zip for you later today. I use recovery 5.0.2.8, but I don't think that it matters.
Edit: Here is the link - Link

Flash Player Stopping
Stripped down ROM is great - now have more room for downloading apps.
One problem I've come across on this ChaCha is that Flash Player stops working (returns to home screen) after around 2 seconds of playing anything.
Anyone else had a similar problem?

As you can see from the screenshot below I don't have that issue. Try different flash player for armv6 devices. There are few, just google it.

dta2sd
Little suggestion. If you are planning to use this rom for a longer time, after your setup, copy your data from your sd card to your computer, go into clockworkmod recovery, in advanced options partition your sd card (I set sd-ext to 256, don't need more) and reboot. After that download terminal emulator from play store. In terminal type this:
su (then press enter and allow superuser permissions)
a2sd reinstall (enter and wait for your phone to reboot. It will take some time)
After it is booted enter this:
su (enter)
a2sd cachesd (press enter and wait for your phone to reboot. It will take some time).
The end result you can see in the attached screenshot. After installing all my apps I still have over 120mb free.
Of course, after everything is done copy your data back to sd card.
Regards

Added wifi tweak to the first post. It works for me, hopefully it will work for you as well.

languages included in europe rom
What languages are included in this ROM?
Thx!

Thanks for this rom, great daily use

Great Rom, Thank you!
This is the best ChaCha rom I have used so far. Everything works great super fast flash even works!
YouTube can play 240p with no lag, any higher and it will.
BBC iplayer crashes but I have yet to find a rom that bbc iplayer will work on when it comes to the ChaCha.

Perfect rom but can u create a RTL fix for arabic support ?
thanks.

ZTE V975

Hi all.
I have a new ZTE V975 and i have it root and with gapps but i have a problem with Play Store compatibility. "Financial" apps aren´t compatible with the phone. I think that it is a location problem in build.prop
The problem is that i dont know modify it.... can someone see this build.prop archive to see if can change it to improve compatibility?
If someone want to see it i can upload it.
Thx.

Hi gargamelxda,
I've got the same phone and noticed the same thing with certain apps on the play store. Basically what I found was the device was missing a bunch of Google support files that were in GAPPS zip. Now I wasn't able to flash the GAPPS.zip file through the built in recovery as it wasn't signed correctly for this phone and there is no custom recovery available yet.
What I ended up doing is extracting the GAPPS zip file to my SD card then used the root explorer function in ES File Explorer to mount /system as RW and move the majority of the extracted /system files to the same location in the device root /system folder. Couple of things to remember though:
1) Don't overwrite anything that's already there (there was only 2 or 3 files already there by memory)
2) If the folder already exists don't copy the whole folder but rather all the files under that folder as you may either stuff up the folder permissions or create a new folder as the android file are case sensative (eg the folder "Apps" is different to "apps")
3) There are some apk files you won't want to copy like the "onetimeinitializer.apk" file as it will run the google first time initialization next time you reboot which may stuff up your settings (although if you're planning on doing a factory reset after doing this it should be OK and all the changes you've made will stick as they're in the /system folder). I also found that if I copied "LatinIMEDictionaryPack.apk" and "GoogleTTS.apk" they would constantly crash after the reboot.
4)Make sure you set the permissions after you're done copying to "-rw-r-r--" for the files and "drwxr-xr-x" for any new folders you create. you can do this individually with ES File Explorer but if you're ok with linuix command line you can do it in batches (eg all files with the apk extension) via the Android Terminal Emulator app or ADB Shell over a USB connection to a PC. I don't remember the exact command lines I used but if you do some searching on this forum you'll find them easy enough.
After a reboot the apps should now be available to install (at least they were for me) via the Play Store.
Usual disclaimer - If you stuff this up you may brick your device and I'm in no way responsible for it.
Hope that helps
Cheers

I spent a few days trying to install Google Play the cyanogenmod way, following instruction on a spanish site similar to what other's have posted here. The idea is to mount the readonly systemfolder using the bootloader and insert/write systemapps into system/apps
I succeeded but for some reason launching google play was killed instantly by some resident app on the phone.
On the MIUI forum somebody called Eric Xiang built a google play apk that kills the resident blocker and installs googleplay !
xttp://en.miui.com/thread-3998-1-1.html
I now have a fully operational V975 (4.2.2) with the latest official build B06 and google play.
Out of the box the phone is unlocked but not rooted.
To root it, install xttps://dl.dropboxusercontent.com/u/15286951/update.zip using the bootloader (vol+ and power on, when v975 wakes up release power but keep vol+ pressed for a few seconds more, then browse to update.zip. Obviously you preloaded the zip on a sdcard.
If ZTE release firmware B08, you'll have to root it again.
Battery life is excellent, as well as speed, camera, GPS fix is instant. I had a iocean X7 that i killed trying to get the gps working, but v975 feels a lot faster vs the X7's MTK 6589 quadcore 1.5ghz. Granted there's less pixels to move around.
One caveat : iCoyote does not install because of binary incompatibility ? This is an x86 device.
I also discovered the existence of AmazonMarket. Not as complete as GAPPS, but a nice fallback market. And most of the google stuff is installable by apk anyway, so living without GAPPS was not as bad as it looked.
Thx to Eric Xiang, his app prolly opens up all androidphones to googleplay, chinese phones can flood the rest of the world now
the above was two days of research guys, enjoy it !

Hey
I'm going to get this phone in the next few days. As far as I know, for 99%, I'm not going to have Google Play on it.
What is the easiest way to install Google Play on it?
I already downloaded B06 since I want to have the latest build.
