Best ROM for ZTE Blade/Idea Blade


I have been trying several ROMs to find out which one is apt for my Idea Blade. Saying more specifically, which ROM is capable of running smoothly on my 256MB RAM smart phone. I  have tested Swedish Snow RSL7(Android 2.3.5) and its a stable rom for day-to-day use. But then heard about Cyanogenmod 7.2 which is based on 2.3.7. Later I tried ICS ROMs but all are disappointing except Burstlam’s AOKP ROM. I’d say it is the best ICS ROM to run on a Blade with 256 MB RAM.

But I am not saying it is the best ROM yet. I have tested several others too, Paranoid, Cyanmobile Experience, Konstat’s, Tilal’s, JOYOS, etc. But I wasn’t satisfied at all. Somewhere I am finding some issue, either by lack of speed or lack of applications and all.

Finally I decided to switch back to CM 7.2 based on 2.3.7. I had to made some tweaks in this ROM and then its working awesome and I’d say its the best ROM for a blade with 256 MB RAM. Following are the changes I made.

I installed CM 7.2 along with GAPPS(Google Apps). There are many applications are included which can be removed to save some space. Now installed Root Uninstall, which is used to uninstall system application and user applications. You can remove Cyanogen Wallpapers, ROM Manager, Google Car home, DSP manager etc. These applications will run in background which will consume some ram. Also you can remove music visualization wall paper, android live wall papers etc.

Always remember, do not install any application on your android device unless you use it often. Most of these applications will run in background and reduces overall performance.

Now you need to install S2E and Swapper from Google Play Store. S2E is application to SD card  utility. Install it and check the options Applications, Download Cache and Private Apps. DO NOT OPT TO MOVE DALVIK CACHE AND APPLICATION DATA. it will reduce the performance of the system. Also in settings, opt to mount EXT4 without journaling and set read buffer options. Set the read buffer option to 2MB. Now comes to the other application, Swapper. This application let your device to use SWAP space so that some RAM space is freed.

Open Swapper and goto settings. Set the swap space to 128MB and swappiness to 10. Now save the settings and reboot your device. See if you feel any difference. Of course, you will!!

If you want to see how ICS performs on this device, you can try installing CM9 AOKP ROM. But it lacks FM and YouTube HQ and sometimes it is laggy. A better option for day-to-day use is CM 7.2 with above tweaks.

In a brief,

  1. Install Cyanogenmod 7.2
  2. Install root uninstall and remove unwanted applications
  3. Install S2E and Swapper for additional performance improvements
  4. Remember, do not install applications if you do not use it often

Cyanogenmod 7.2 RC2


After a while, Cyanogenmod RC 7.2 RC2 has been released. It was said that 7.2 stable release will be released soon. However it is noticed that, a subsequent release candidate is released for ZTE Blade and implies there may be a delay for stable version for this device. Whatsoever, with this release they assure many bug fixes and though a release candidate, it can be used like a stable version.

I am yet to check out the feature of this device though it was released on May 9. Meanwhile I was testing CM9, yeah the Ice Cream Sandwich version in my Idea Blade. Unfortunately it is not working after reboot and my SD card got corrupted. The interesting thing is many service personals yet to learn how to root an Android Device and I had to find out the actual issue from Googling and fix it by myself!

Well, as I said I am gonna check out this version and update you all soon. Stay connected and check out my previous posts. Please like and follow my blog and my facebook page.

Cyanogenmod 7.2 RC1: Worth Trying


Cyanogenmod has released a release candidate for its latest ROM based on GIngerbread 2.3.7, Cyanogenmod 7.2. This is the final release in 7.x series and is coming with some couple of back ported features and fixes from 4.0, Ice Cream Sand witch. This particular version supports 20 new devices and in a total of 70! No official confirmation on date of final release. I had tested this ROM in my Idea Blade and found very interesting.

Comparing with the previous version, 7.1, this version has improved a lot. A notable change is predictive text dialer. Now you can directly search for a contact from dialer by simply pressing the numbers. This is indeed a good thing. Next, it supports installation in SD cards. Yes, previous version also supported this feature, then what is the new thing? It is, now you can install any application, I said any, to the SD card by default. That is interesting, no!

ADW is the pre-installed launcher in it. With some tweaks you can make it more faster. I prefer not to install any other launchers unless you are using a high memory device. This version has cyanogenmod’s propitiatory features such s theme support, DSP equalizer, and CPU overclocking etc. Unlock screen options are updated. Now you can completely disable the unlock screen or change its style. Also, you can move the notification bar to the bottom of the screen. This option is available in the tablet tweaks.

One major issue reported with this RC is that, it eats battery like anything. Battery is draining fastly and also some of the applications are crashing. After reviewing the overall performance, I PRESUME 7.2 will be a good alternative.

How to free ROM in Idea Blade


Idea blade is coming with a ROM of 256 MB and user space will be nearly 60 MB. Once you start installing applications or updating it free memory will be decreased. Here are some useful ideas to free up your ROM.

Many pre-installed applications get updates via Google Play. Once you update these applications it is not ORIGINALLY updating the app but installing a newer version which in turn eat your internal memory. That is why when yo reset your system, your applications are able to return to original version.

There is an application called Apps2Rom is available to download. It helps to check if your device has duplicated applications. i.e., original application in ROM and its updated version. Your phone should be rooted to use this application. Once you open this app, you can see the list of applications in it. If any application is duplicated, (this can be identified by looking into the dot near the application. If you see two green dots near any application it means it is duplicated) you can replace your old version with latest one. By doing is you are uninstalling factory installed application and installing a fresher version. Further updates to this version will not create any duplicates.

Also, if your phone is rooted, you can try uninstalling your factory installed applications such as games, facebook,twitter,youtube,opera mini etc. This can save a lot of space. Many applications such as Root Uninstall and Root uninstaller etc, are available in Google Play for download. Try these.

These techniques are not limited to Idea Blade and can be tried in all supported Android devices.

Upgrading Idea Blade from Froyo to Gingerbread


Idea Blade is a customized version of popular android device ZTE Blade. This phone is being sold in many countries under various names. In India, Dell and Idea are selling this handsets under the name Dell XCD35 and Idea Blade respectively. Though these are primarily from ZTE, it differs in hardware. Dell XCD35 is the original ZTE device shipped from Europe with 512MB intenal memory whereas Idea Blade is a Chines make with only 256 MB internal memory. However this device shows a wonderful performance while comparing with its competetors.

As you know Android is an open sourse software platform, anyone can make changes in it. However Android phones do not handover the root licence to the customers. Rooting is the privilege to access the system files. Since these files are vulnerable to attacks, typically rooting is not allowed by default by Android phone vendors. There are various softwares avaiable in Android Market, now known as Google Play, for gaining root access in android devices for free of cost and as paid versions. However rooting voids the manufacture warrenty!

There are many customized ROMs are available and it can be replaced by the stock ROM. Being a demanded android device, ZTE Blade is in the supported device list of the most popular ROM, Cyanogenmod.Though Idea Blade is upgradable to Android 2.3, no official packages are available yet. However still you can try two customized ROMs, Swedish Snow RLS6 and Moldovan-Mile-High-Mountain-Pie-RLS9. The first mentioned one is latest one and is recommended coz the other have an issue with camera.Cyanogenmod 7.1 is tested Idea Blade and it is found working well. After a clean installation without any add on packages such as google apps, there will be a free memory if 130 MB. Swedish Snow is pretty good and once it  is installed there will be a free memory of minimum 115MB.

Here is the step by step guide to upgrade Idea Blade from Froyo (2.2) to Gingerbread(2.3). Again, this is an unofficial release and rooting process will void your manufacture gurantee. Also, try these at your own risk!

1. First of all, download the  package  file from here and copy it to the SD Card. Then the device must be rooted. Download Z4root and install it in the phone. Copy the installation file into the SD card and open it using filer or any file explorers. Make sure to enable Unknown sources in Settings > Applications in order to install the package. Also enable USB debugging in deveopement page. (Note: This whole process will wipe the entire data in the phone. You should take back up of your contacts and whatever data you need).

2. Once it is installed you need to root the device by selecting permanent root. You may be asked to give super user privilege and allow it. Once rooting is completed, system will reboot automatically.

3. Download another software ROM Manager from Android market and install it. This program also should have super user privilege.

4. It is highly recommended to take a backup of your current ROM so that at any point, you can restore your stock ROM(Original ROM). You should have sufficient memory in SD card to take a back up (aroudn 300-500MB). Meanwhile you may be asked to install and addtional package clockworkmod recovery. Click on yes and it will be automatically installed. No worries!

5. Once back up is complete, click on the reboot into recovery button in ROM manager. Phone will reboot into recovery mode. (You can manually do it by shutting down the phone, restart it and press power button and volume key while booting. )

6. Now the real play begins. You need to click on wipe data/factory reset option. You can use volume keys to navigate and Home key to select. Click on this option and you will reach confirmation page. Select Yes and it will wipe all user data in some moments. (Remember, with this process whatever there in the phone will be lost.)

7. Now return to the main screen and you need to wipe cache and dalvik cache as well. Once these two are done with come to the main screen.

8. Now choose install from Zip in SD card. This will open the SD card file and you need to select the zip file and then click on home button. Installation will finish in some minutes. Stay cool!

9. Once installation complete message is shown, click on reboot now. First boot will take time upto 10 – 15 minutes. Once everything is set, you will see the home screen.

10. Additional packages and advanced knowledge can be obtained from the developer page.

Installation Procedure for Cyanogenmod

  1. First of all you need to install Z4root and root your Idea Blade. Run a permanent root and restart your device. Now install ROM Manager from market. Though ROM Manager has a rooting option, it is not capable of rooting Idea Blade and Z4root is recommended.
  2. In ROM Manager, take a back up of your current ROM. You will be asked for installing clockworkmod recovery, press OK to continue. Once clockworkmod recovery is installed, try back up. Phone will be rebooted once back up  process is completed.
  3. Open the ROM Manager again and click on Download ROM and under Free category you can see various free to use custom ROMs. Click on Cyanogenmod and it will show a list of ava ilable updates. Install the latest stable version(unless you want to view the latest features in a developer preview). You will be asked for opting additional packages. Google Apps is recommended.
  4. Once download is done with, it will show Pre-ROM installation options. Choose to empty cache and dalvik cache.
  5. System will boot into recovery and start installing the Cyanogenmod into your Idea device.
  6. Once installation is finished wait for first Cyanogenmod loading. It will take some minutes and your Idea is ready with Cyanogenmod
