U9200 AIO guide
This guide is made by me, but I've collected information from many others.
Special thanks to: arkedk, Urmet77, lee140685, faust93, spanorg, kiprap and others.

First of all:
1. I am not responsible for ANY bricked device! You are doing this at your own risk.
2. Downloas are located here. Most of my uploads are heavily compressed by 7zip. Only 7zip will unzip correctly.
3. Install ADB and FASTBOOT drivers for making stuff in this guide work. Very easily done with: 15 seconds ADB Installer by Snoop05 @ xda
Eventually: Android SDK | Guide by demkantor | Guide by TeamAndroid
4. Backup stuff you want to keep. Easy with tools such as: MyPhoneExplorer, Super Backup, Titanium Backup or others. (Use Google)
5. Other things you should know:
→ Reboot phone to recovery: Turn on while holding volume up + volume down. Or through ADB: "adb reboot recovery"
→ Reboot phone to fastboot: Turn on while holding volume down. Huawei logo will appear and won't disappear. Or through ADB: "adb reboot-bootloader"
→ Shut down phone if it freezes: Hold power button until dead.
→ For ADB to work, debug mode must be enabled, and you must choose "Hi suite" as USB connection mode.
→ Some Huawei ICS ROM's comes without the FM radio app. If you want it, you can install this apk. NB: ONLY ICS (Android 4.0.X). For JB: B704 was the first version to include FM radio.
Here is "ascend-p1" forum category on xda: http://forum.xda-developers.com/t/ascend-p1

Gain root access (Works on ANY Huawei stock firmware. Inspiration taken from arkedk's thread)
TWRP has the ability to root our device, regardless of firmware version!
1. Download TWRP v2.6.3.0 (img). Unzip it, and place the .IMG in "C:\Program Files (x86)\Android\android-sdk\platform-tools" folder.
2. Turn off your phone. Restart it while holding volume down (Fastboot mode). Connect your phone via USB. (ADB: adb reboot-bootloader)
3. In the "C:\Program Files (x86)\Android\android-sdk\platform-tools"-folder, hold shift while right click. Choose "open command window here".
5. Write "fastboot devices" to verify that the computer detects your device. If not detected, you failed install Fastboot drivers. (Look at the top of this guide)
6. Write "fastboot flash recovery recovery.img". This will flash/ install TWRP to your device. (Given that your recovery file is named recovery.img)
7. Boot into your new recovery, TWRP. (Volume + and - together at startup)
→ Go to the "Mount" menu and mount System.
→ Then go to the Reboot menu and reboot the system.
→ When it detects you are not rooted, TWRP will ask if you want to root.
→ Swipe to do so and let it boot back into the system.
8. Hit the SuperSU icon and let it setup for the first time. Either by downloading a flashable zip or by going to the Play Store. Both methods works.
9. You should now be rooted!

Install/flash stock or custom recovery. (Root not required.)
1. Download the recovery you want. Place the .IMG file in "C:\Program Files (x86)\Android\android-sdk\platform-tools"
2. Turn off your phone. Restart it while holding volume down (Fastboot mode). Connect your phone via USB
3. In the "C:\Program Files (x86)\Android\android-sdk\platform-tools" folder, hold shift while right click. Choose "open command window here".
4. Write "fastboot devices" to verify that the computer detects your device. If not detected, you failed install Fastboot drivers. (Look at the top of this guide)
5. Write "fastboot flash recovery <recovery_name>.img".
→ Let's say the recovery file is named twrp.img. Then you will type: "fastboot flash recovery twrp.img"
6. If unsuccessful, try again, be very careful about typing it right. If successful, write "fastboot reboot" to reboot your phone. You are done.

Install any Huawei stock firmware, regardless of version (even from custom rom)
- This will delete everything on your phone's internal memory, and you will loose root.
- The easiest way is by first flashing Intermediate Pack (B123). This is a stock Huawei ROM that will flash regardless of previous firmware version. Any Huawei ROM then will flash straight from Intermediate Pack. No build.prop modifications needed!
- Chinese versions don't have GAPPS installed. This must be installed through a custom recovery after flashing the firmware.

1. Grab "Intermediate Pack", desired firmware version, intermediate FashPack. Links in bottom of this guide.
2. Take the RECOVERY.IMG out of intermediate FlashPack, and Install it through the steps above. (fastboot flash recovery recovery.img)
3. Place "Intermediate Pack" UPDATE.APP on your SD-card. The file structure MUST be: (Root of SD-card) dload\UPDATE.APP
4. Boot into recovery (Volume up+down when powering on the device). This should start flashing procedure of B123, Intermediate Pack. If it doesn't work and you come from a custom ROM, you must change build.prop to the one included in Intermediate Pack FlashPack. See "FAQ" on how to replace build.prop.
5. After install, it will boot. Now switch the UPDATE.APP from Intermediate Pack with the one from desired firmware version. ((Root of SD-card) dload\UPDATE.APP)
6. Boot to recovery. The firmware flashing procedure will start.
Chinese version extra intructions. This is the time to install GAPPS! B704 extra instructions! arkedk has made a zip to enable all languages in B704. Grab Enable all languages in B704, by arkedk
→ FIRST boot the phone after the firmware installation has succeed.
→ Grab GAPPS corresponding to your android version. (I recommend miuiandroid.com's GAPPS lite, as they removed all unusefull stuff) Place the .zip on the sd-card. Place language enabler.zip on the sd-card aswell
→ Install a TWRP v2.4.4.0 recovery
→ Boot into recovery. Install GAPPS.zip. Install language enabler .zip aswell
→ Reboot. TWRP will ask you if you want ROOT access. Entirely up to you! For the language enabler to work, you must do a device reset. Relax, GAPPS should be there after the reset.
7. Done! If you want root access, check root guide on top. You can remove chinese system apps with Uninstall Master. Weather, baidu, and chinese market won't work outside china anyway. REQUIRES ROOT!
OLD METHOD
Install any Huawei stock firmware, regardless of version (even from custom rom) B229 is a bit different. See "FAQ" at bottom.
This will delete everything on your phone's internal memory, and you will loose root.
Your phone must be rooted for this method to work (replacing/modifying build.prop. Check FAQ about build.prop if you have any questions)

1. Grab firmware (UPDATE.APP), recovery.img and build.prop (Both included in attached FlashPacks) for desired firmware version. Links in buttom of this guide.
2. Place UPDATE.APP on your SD-card. The file structure MUST be: (Root of SD-card) dload\UPDATE.APP
3. Install recovery through the steps above.
4. Download and open "Universal Android AIO Flasher Tool$" to replace build.prop:
→ A: Open desired build.prop in notepad, notepad++ or similar. Copy everything.
→ B: Connect phone in ADB mode (See "First of all" ↑ ).
→ C: Open "Universal Android AIO Flasher Tool$". Go to "Build.prop Editor"-tab
→ D: Insert what you copied into the empty text field.
→ E: Click the "save" button and then "Flash to device". You must grant access with SuperSU (or whatever uperuser access management tool) on your phone.
→ F: If successful, you must click "Reboot device" for the changes to take effect. Let the phone reboot.
Manually: "adb pull /system/build.prop" to get the build.prop from your phone.. "adb push build.prop /system/build.prop" to push build.prop to device. "adb reboot" to reboot it (Must be done)
5. After reboot, check "Settings -> About" to check if stated firmware version has been changed to the one you want.
6. Turn off your phone. Restart while pressing volume up + volume down. The firmware flashing procedure will start. If not, you have done something wrong.
7. Done.


Install custom firmwares/ROMs (Root not required)
- This will delete everything on your phone's internal memory. Backup stuff you want to keep.
- All custom ROMs i know is pre-rooted, so nothing to worry about there!
- You will need custom recovery for this to work. Look above.
Depending on firmware, GAPPS (Google Apps) might not be included and must be flashed afterwards if it's wanted. I recommend miuiandroid.com's GAPPS lite, as they removed all unusefull stuff

1. Download desired 3rd-party firmware, it must be a CWM/TWRP flashable .zip. Place it on you memory card. If you're flashing GAPPS aswell, place gapps.zip on the memory card too.
2. Reboot you phone to recovery.
3. Wipe everything the custom firmware needs to have wiped. Generally cache, dalvik and user data.
4. Flash the firmware .zip. Wait for everything to finish!
6. Restart the phone. It will use alot of time the first time. If it uses more than, let's say.. 7 minutes, something is wrong (bootloop).
You can eventually try these steps:
→ Wipe cache, dalvik and userdata with CWM.
→ If this does not solve the problem, check the files and reflash. If it still bootloops: The files don't work with U9200.
If you are going to flash GAPPS, now after the first boot is the time to do it. Boot into recovery, then flash the GAPPS .zip corresponding to your firmware version.
7. Restart and enjoy!

"Ey, Olav! Do you know any other usefull stuff I can do to my rooted phone?"
These settings can be edited by using the app Root Browser, for instance.

Boost GPS-perfomance by changing default server to the respective one for your country. Should make the GPS faster and more precise.
The file holding this information is located in: /system/etc/gps.conf
Find respective gps server (NTP) here: http://www.pool.ntp.org/zone/@
I'm from Norway. My customized gps.cfg looks like this:
Code:

Fix GPS log bug found in some Huawei ROMs. There seem to be a bug, where stock Huawei ROMs will create huge unnecessary GPS logs, that eventually will fill your entire sd-card with trash! (We are talking several 100 MB's of logs!).
Disable log keeping by editing a setting in this file: /system/etc/gpsconfig.xml.
Edit: "cLogEnabled" from "true" to "false". Then delete all the logs in: system/data/gps/log.
FAQ

Install latest baseband version
Why? Baseband / radio.img is the software controlling everything that has to do with signal. Newer baseband versions can boost your performance + make battery last longer. It might make things worse, but generally newer means better.
How? There is no way to extract radio.img from Huawei firmware at this point. So only way to do this is through flashing a stock firmware from Huawei containing the baseband (radio.img) version you want. (New firmware sometimes includes updated baseband version). If you want custom firmware/ROMs you can flash them over it, baseband version will remain/ radio.img/baseband is not included in custom firmwares/ROMs. Flashing any Huawei firmware will replace baseband with its own version.
For flashing procedure, see "Install any Huawei stock firmware, regardless of version you are on (even from custom rom)"

GAPPS
Why? You want google applications, but it's not included in the ROM you've flashed.
Which? GAPPS is made for every android version (ICS=4.0.x, JB=4.1.x and JB=4.2.x). Make sure you pick the right one! (Links in download section). I recommend miuiandroid.com's GAPPS lite, as they removed all unusefull stuff. Can potentially make your device faster.
How?
- Download GAPPS.zip, move it to your memory card.
- Use custom recovery such as CWM or TWRP to flash it.
Remember:
- Has to be done after the ROM is flashed (obviously) and it's reccomended to boot the ROM once before flashing GAPPS.
- All Huawei stock firmwares (Except chinese versions) have this preinstalled.

What does "Root"/"Root access" mean?
- System files is not editable on stock firmware. Editig these can potentially make your phone into a brick. To remove these restrictions follow the steps in my guide.
- Rooting will in most cases destroy warrenty!
- MIUI, CM and other custom ROMs are pre-rooted[/I]

What is build.prop?
- This is a text file stored on your phone, which tells the phone about what firmware version it has + some other stuff.

Why replace build.prop?
Build.prop stores lots of settings and info about your phone. Changing it is most commonly used for tricking the upgrade procedure to think the firmware on the phone is compatible with the update.
- Huawei firmware updates is restricted to some few firmware versions. But they have made a "Intermediate Pack" which will flash from ANY stock huawei ROM. All huawei ROM's will flash from this intermediate pack without the need of changing build.prop. Think of "Intermediate Pack" as a intermediary for getting the firmware version you want.
- If you come from a custom ROM, and intermediate pack won't flash (verification fail in recovery), you must change build.prop to any stock huawei build.prop for it to work.

How to replace build.prop?
Phone must be rooted!
NB: There's a chance your custom ROM won't boot because of using stock Huawei build.prop with it. In case of updating to Huawei stock firmware, be smart. Flash stock recovery, and add the update.app to SD card BEFORE you change build.prop!
- Get desired build.prop (included in my "FlashPack" files.
- Download Universal Android AIO Flasher Tool$, by "fonehacker".
- Plug your phone in ADB mode. Open the tool above. Go to build.prop tab. Open your recovery. Press save. Then flash it to your device.
- Device must restart for the changes to work. The tool will ask you about this, and you press YES.

(Alternative: Take a custom rom zip (MIUI for instance), open zip without unzipping (Use 7-zip), delete all the folders in the /system, including build.prop. Drag desired build.prop to /system folder. Flash this file from a custom recovery, such as CWM or TWRP. No root needed.)

What is boot.img for?
- It's a file that get flashed to your boot partition on the phone. This file is managing the booting process of your phone. This file is included in all ROM's, therefore there is no need for manual flashing. If the boot partition get's damaged in any way, flashing a boot.img made for the same firmware can fix it. Don't try boot.img from different firmwares/android version!

Why is boot.img included in your FlashPacks?
- ROM developers might use it for developing new and better roms. If you just are updating your phone, you will have no use for it.

What is EmUI?
- Huawei is making a custom version of android for their phones. This project is named Emotion UI, EmUI in short.

What is latest firmware(s) for my U9200?
- The download section always contains latest version of Huawei firmware. If there is a new version I have not listed, tell me

What's the difference of "boot recovery" and "flash recovery"?
Boot recovery will make your phone boot from the recovery file stored on your computer (Through fastboot, your phone is connected with usb)
Flash recovery will replace what ever recovery you already have on your phone.

Can I remove/change battery?
- It's not meant to be possible as there is no plastic cover you can remove without disassemble the phone. There is a small bolt underneath the SD-card cover. I think that's the place to start if you want to open it. This will most certainly break the warrenty. If the phone's hardware misbehave in any way you should contact Huawei or the store you bought it from.

When I tried the jelly bean emui, I thought it was a bit of a ripoff of MIUI. I like MIUI better.
