Tips Upgrading ROM - Avoiding Error on Upgrading and Using Custom ROM

Tips Upgrading ROM - Avoiding Error on Upgrading and Using Custom ROM. Using a custom ROM with your Android Smartphone have many positive impact to your phone. For me, after using Custom ROM, upgrading from eclair to froyo and after that froyo to gingerbread, I can feel many different in this Custom ROM.

The latest ROM in this blog is Update 26 Gingerbread ROM by joiloroi.

Some change that Android user want most like battery lifetime usage, performance speed, and compatibility with Android Applications and games. And many ROM or I can say that is the main reason to use Custom ROM. The developer of each ROM also keep their ROM to satisfy their users.

But there is a time that we got error while or after upgrade the ROM. Maybe you familiar with the word "Force Close" on your Android. There maybe because the ROM bug or you don't install the ROM in the right way. This post will give you the best way to install ROM, or I can say My best way :D

Backup All your important data (Applications, Contact, etc)

It's very important to do a backup before do anything. I always backup all my Applications and contact before doing ROM upgrade. For Applications backup I' using Huawei Backup. Another applications is Titanium Backup.

Download ROM that Compatible with your Phone!!!

Find ROM that compatible with your Android Smartphone :D

Wipe All Data Before Install ROM

That's why backing up applications is very important. You can also upgrade ROM without wiping data, but the safest way if you don't want to getting "Force Close" or system reboot.

What to wipe:
~ Wipe Data/Factory Reset
~ Wipe Cache Partition
~ Wipe Dalvik Cache (Advance Option in recovery Mode)
~ Wipe Battery Stats (Advance Option in recovery Mode)
~ Format /boot (Important: Only do this if you still have problem after upgrade ROM, do this and repeat all the upgrade step. You can find this in "mount and storage" option in recovery mode.)

Install the ROM and do a clean reboot after the ROM installed

Do not install anything after you successfully installed the ROM. Reboot your phone right after you get the desktop. If you having problem in accessing the desktop after the second reboot, that's mean something not right. You need to wipe data again and reboot. If it still a problem, do Format /boot and re-install ROM.

Do not Install Applications at once

With Huawei Backup or Titanium Backup, you can restore all your applications at once. Don't do that! Just install 2 or 3 applications and reboot after it.

That's all!!!

Upgrade Android Huawei U8100 Eclair to Froyo

Huawei Aviator U8100 comes with Android OS v2.1 (Eclair), but you can upgrade it to Android OS v2.2 (Froyo). You can upgrade Android OS by upgrading the ROM, and my favorite place to learn that is at [ROM] All Huawei U8100/U8110/U8120 ROM-s in one place xda-developers Forum.

Before you go for upgrading your Android, make sure you have a good reason do that. Because if you did something wrong, your Android Smartphone might be useless anymore. Did you have a good reason???

Okey, let's began to upgrade our Android Smartphone OS from Eclair to Froyo. First thing we have to do is make sure you meet all the requirements to upgrade your Android OS. The requirements are :

1. Huawei Aviator U8100 Android Smartphone
2. Memory Card / MicroSD Card
3. ClockworkMod Recovery or AmonRa Recovery
4. ROM File
5. Full Charge of Battery

Huawei Aviator U8100 recovery mode didn't support for upgrade OS from zip file, there for we need to install new recovery mode. I have use both ClockworkMod Recovery and AmonRa Recovery, and I'd prefer ClockworkMod Recovery. So please go to Install ClockworkMod Recovery for Huawei U8100 Android Smartphone for step by step instructions.

After installing new rocovery mode, the next thing is to download the ROM you want to use. In this tutorial I'll use [ROM][U81XX] Cyanogen mod 6.2.0 Beta 1. The ROM is in zip file.

Now you have your U8100 with ClockworkMod Recovery installed and have Cyanogen mod 6.2.0 Beta 1 ROM file. It's time to flash your Android Smartphone.

1. Format your MicroSD using FAT32 File system, or if it's already FAT32 just place the downloaded .zip ROM file to your MicroSD card.

2. Turn off your phone and enter the recovery mode by pressing Call + Volume Up and Power On your phone while keep pressing the button.
3. Release the button when entering the recovery mode. Below is the ClockworkMod recovery looks like.
4. Now choose "install zip from sdcard" and navigate to "" (ROM file)
5. Wait untill the flashing finish, then choose "wipe data/factory reset" and "wipe cache partition"
6. Go to "advanced" and choose "wipe dalvik cache"
Note : You have to wipe all the data if you are upgrading the OS, but if you just change the ROM and not upgrading it, you can leave it all without wiping it. My recomendation is to wipe all the data even if you are not upgrading it ^_^.
7. Choose "reboot system now" to reboot your phone to a new OS.
8. That's it, Now you have your Huawei Aviator U8100 Android Smartphone with Android OS v2.2 (Froyo)
