Do not flash recovery
DSTL1 / N21 owners, DO NOT FLASH RECOVERY.
Our recovery is different from HTC models. If you wish to figure out the internals of recovery you need to learn how to unpack.

If you have not heeded my warning and flashed your recovery, do not despair.
Use my original DSTL1-recovery.zip

Or Slemmen's original N21-recovery.zip

Don't forget to unzip and then rename to recovery.img and then place in update folder.

This is the original DSTL1 / N21 recovery, no modifications as of yet.

P.S. they are exactly the same

But no problem only with my recent root access, isn't it?

You should not have a problem, unless you specifically attempted to flash recovery.

The DSTL1 is partitioned this way:

cat /proc/mtd
dev: size erasesize name
mtd0: 00100000 00020000 "Bootloader"
mtd1: 00400000 00020000 "boot"
mtd2: 00400000 00020000 "recovery"
mtd3: 05000000 00020000 "system"
mtd4: 01000000 00020000 "JFFS"
mtd5: 08000000 00020000 "userdata"
mtd6: 006a0000 00020000 "cache"
mtd7: 00080000 00020000 "BBT"

When you updated using my ROOT package you flashed the "system". I am referring to "recovery".

Once I get a chance to hack "recovery" then DSTL1 users can begin to start using nice tools like those included in RA_Mon's Recovery Image (which is based off of Cyanogen's Recovery Image).

Knock Off DSTL1
Woah! Looks like re-branded DSTL1 (aka knock off) has entered the scene: http://phandroid.com/2009/10/26/knoc...here-sciphone/ SciPhone N21

I wonder if anyone has it. I wonder if my root package will work on their phone - should be same hardware a slightly different Android build... Would be cool to know! Anyone?

Woah! Good to know! It looks like Russian RoverPC has 850 band! I don't think my device has the 850 band

By the pictures it looks like their firmware is General Mobile's! Which means my update will surely work on all cloned models... give or take language settings.

I am working on a Recovery image for the DSTL1 (there is progress).

In the meantime, I ADB ROOT is possible for both Recovery and ROM... I have not released these because I don't think anyone needs them - they are mostly used by developers or to implement some sort of hack.

I will hold off on releasing a ROM build / Recovery image with ADB ROOT unless someone has a good reason for it. (PM me)

Please note that one can attain root in adb simply by typing "su" in the console and hitting "allow" on their device.

Remember, although DSTL1 users can now enjoy root it will only be beneficial to everyday users in the form of programs that require root. Otherwise you should hold off doing all the other cool root things you have been reading about (i.e. upgrading to someone else's ROM or Recovery)

Although if you are feeling brave, by all means experiment and share your findings here - but I warned you

Manufacturer revelations...
The DSTL1 was actually designed by a company called Yuhua. The board is called the X2. Found here: http://www.yuhuatel.com/english/x2.php Even Yuhua's site is sporting General Mobile's imagery, which must mean that General Mobile contracted the company to design them a phone or Yuhua actually stole General Mobile's better phone renders.

Which explains why there are a bunch of clones popping up. The question I am interested in getting answered is who developed the ROM for this X2? General Mobile branded the ROM with their logo, but images of NL2 and RoverPC both show a General Mobile logo... so maybe General Mobile redistributed the ROM while Yuhua provided that hardware (design). Notice also that Yuhua's site makes no mention of a Dual Sim architecture, but all the clones have it.

The hardware is not capable of 3G, Edge at best. But two different "band" packages are available: 900/1800/1900 MHz and 850/1800/1900 MHz

I use U.S.A.'s AT&T service with this hardware and it suffers greatly because my hardware lacks the 850 band - thus I am limited to only 1900 and AT&T's support on this band is weak (I get EDGE sometimes, mostly G). On the other hand had I gone with T-Mobile I would have been well off as they are exclusively 1900. Though I would have never reached 3G I would have been on a solid EDGE connection everywhere unlike partially with AT&T

The X2 also claims to be Digital Compass capable as well as GPS... I have seen 0 support for either - granted the phone comes lacking Google Experience applications, I have tried other software (i.e. Waze) that rely on GPS and they have failed. My goals are to get GPS working as it is a necessity to me - probably via external GPS and BlueTooth connection once General Mobile releases a 1.6 update.

As a side note the device is also available in CDMA flavor, but in silver. You can see the silver phone renders are all small unlike the black GSM one and none of them have a DSTL1 or General Mobile insignia.

Hi crzyruski,

Actually, I have that phone and your rooted package works fine with it.

In fact, before applying your package, when I started the phone, before having the "Android" logo, Tux was shown.
And after "upgrade", this is now the DSTL1 logo.

One thing however is that the original kernel version was more recent (something like septembre 2009 instead of august. I don't remember exactelly).
So, that's not a big difference though. And actually, I don't see any "regression".

But at least now, I can set up my phone in some other language than English (which was the only provided language in the N21 version). And I hope to be able to do some other cool stuffs soon ;)


For info, the bundle with the N21 is the minimum : 1 battery, 1Go mini-SD card, charger and USB cable (whereas official General Mobile comes with 2 batteries, a greater miniSD + its adapter to SD format, and a leather case).
No CD provided. So, to use the SDK with that phone, you need to use the driver which is available on the General Mobile website.

And as far as I know, N21 is exactly the same as the General Mobile. Actually, it is the same company that builds those 2 phones. It is just a question of branding and of market.
