Idiot's guide to flashing the Xoom (for fun and profit)

This guide is for you that have a new Xoom (WiFi only, US model) with Android 3.1 and want to
- get root access
- enable the external SD card unit
Please note that Android 3.2, which now is available for the US Wifi models, make this guide more or less obsolete. If your aim is to have root access, then there are probably simpler methods.
What you need to do can be encompassed in these following short steps (will be detailed later on) in the following order. Each step is required before you can proceed to the next one. However, make sure that you are very very careful and dont try to take any shortcuts. That may soft-brick your device, and you may have a difficult time to explain that to your wife ... You have been warned!
I strongly recommend you to read the entire guide before trying this. In fact, read it twice to ensure that you have understood everything. If there is wierd stuff that you dont understand, dont hesitate to ask. The reason for me writing this down is that I like to document what I have learned. This is to me an excellent way to ensure that I will remember what I just did. Another reason was that I could not find a single thread that encompassed all steps required. There are many different threads, but noone (that I could find) that really guides you from start to goal. So enjoy and good luck!
I would like to thank LandMaster and cam30era for helping out with advice during my initial trail-and-error session. I soft-bricked my device once and had big problems to get by point 4.3 (avoid overwriting of CWM), but with their encouragement I finally succeeded.
If someone else adapts this guide for the EU model or the 3G model, feel free to drop me an IM and I will update the guide for these devices too. Until then, this has only been tested on a WiFi only, 32 GB device bought in the US. If you brick your 3G or EU bought model, dont call me ...
0. Overview of the 6 required steps
1. Install Motorola USB drivers for your computers (for USB connectivity)
2. Install Java SDK and Android SDK tools (for adb and fastboot commands)
3. Unlock the device for flashing (allowing replacement of recovery and boot images)
4. Install a modified recovery image (ClockWorkMod recovery for Android)
5. Root the device (Allow r/w access to the device filesystem)
6. Flash a kernel that supports the SD card (SD card access, overclocking etc.)​
Steps 1, 2, 4, 5 and 6 require that you download install, image and zip files needed for the flashing.
All this was performed on a Windows XP x86 SP3. Windows 7, Mac and Linux users will probably have to do some steps differently.
Update July 7: I have tested the procedure on Windows 7 x86 now and the procedure is identical to Windows XP.
1. Install the latest Motorola USB drivers
The installation file can be found here
http://www.motorola.com/Support/US-...tware_and_Drivers/USB-and-PC-Charging-Drivers
1.1 Install the drivers and ensure that your Xoom is recognized by the computer
2. Installation of development software
Java SDK 6 and Android SDK (for Honeycomb at least) need to be installed. You can find the installation kits here.
http://www.oracle.com/technetwork/java/javase/downloads/jdk-6u26-download-400750.html
http://developer.android.com/sdk/index.html
2.1 Install them as any other software.
2.2 What I had to do was to manually modify the PATH environment variable. I use Windows XP so I did that by right clicking on My Computer, choose Properties and select Advanced. Here I added the path to platform-tools and Tools
%SystemRoot%\system32;%SystemRoot%;%SystemRoot%\System32\Wbem;C:\Program Files\Intel\WiFi\bin\;C:\Program Files\QuickTime\QTSystem\;D:\Java\Android-sdk\platform-tools;D:\Java\Android-sdk\tools
Note: If the Android SDK complains that the Java Dev Kit cant be found, just press Back and then Next again. Wierd, but that seems to do the trick ... go figure.
2.3 Test that ADB and FASTBOOT works. You should open a command window and go to your Android installation directory. Plug in your Xoom to your computer and write 'adb devices'. Your Xoom should now be listed like this
C:\Documents and Settings\Anders>adb devices
List of devices attached
0288414343813157 device​
Did your device not show up? Make sure that you have USB debugging enabled in Settings / Applications / Development
3. Unlocking the device for flashing
This step will effectively erase the internal storage, including all your apps and settings. Use whatever backup you want to rescure important data before you start.
3.1 Power up and start the Xoom
3.2 Ensure that your device is fully recognized by the computer. A good sign is that the 'Portable device' dialog is activated on Windows when your Xoom has booted. The Xoom should also be seen in 'My Computer'. If not, go back to step 2 and double check your USB drivers.
3.3 Use the command 'adb reboot bootloader' to go into Flash mode
3.4 Use the command 'fastboot oem unlock'. This will trigger a dialog on your Xoom. Follow the instructions on the screen to complete the unlocking. I repeat, this *will* do a factory reset and all data will be lost!
3.5 Once unlocked, the Xoom will restart and work as normal, but now ready for step 4
4. Install recovery image (CWM)
Download the recovery image file and save it to your computer
4.1 Boot into flash mode with 'adb reboot bootloader'
4.2 Install your downloaded recovery image
C:\Documents and Settings\Anders> fastboot flash recovery recovery-Tiamat-R4c-100611-1150-cwm.img​
4.3 Restart the device with 'fastboot reboot'. Timing is essential here, so be alert when the device restarts, or you will have to redo section 4.
4.4 Enter CWM with the following procedure
4.5 Once the Motorola logotype is shown, start counting to 3. At 3, press the Volume Down button. This should result in the text 'Android Recovery' in the top left corner. If it does not work, experiment with the timing ...
4.6 When 'Android Recovery' is shown press the Volume Up button. This should invoke the CWM recovery menu. If that works, then congratulations for reaching this far .
Here is a potential pitfall. If you are unable to enter CWM *before* the device boots into Honeycomb, then the newly installed recovery image will be overwritten by the system default recovery. There are ways to prevent this (see posts below), but I recommend you to redo step 4 instead of messing with removal of system files. But both methods would probably work. Experiment!
5. Rooting the Xoom
The root zip file is located here
5.1 You need to transfer the ROOT zip file to a working micro SD card. You can do this on a computer or cell phone, but the ROOT zip must be located in the root directory of the SD card.
5.2 Insert the now prepared SD card in the Xoom
5.3 Boot into recovery (as described in 4.3). Navigate using the volume buttons and press the power button to select the active option
5.4 Select 'Install ZIP from sd card'
5.5 Select 'Choose ZIP'
5.6 Navigate to the ROOT zip file with the Volume buttons and select it with the Power button. Confirm that you want to install it.
5.7 Everything should indicate success, so back out to the main CWM menu and reboot the device.
5.8 From Android Market, install the ROM Manager app and start it. If the rooting was successful, then ROM Manager should start without any complaints.
6. Flashing a new kernel that supports SD cards (and maybe more ...)
The kernel that I used is described here http://forum.xda-developers.com/showthread.php?t=978013
The kernel zip file is located here
6.1 This step is identical to 5, but swap the ROOT zip towards the KERNEL zip. For simplicity, you may want to prepare the SD card with both zip files at the same time in step 5.1 ...

Looks great. You just might want to give credit to LandMaster and cam30era, too.

Also is this for just USA or all, cos many people brick there xoom if its just for USA only

This is only tested on a US device. OP updated.

Will this wipe all USER data?
Also, is the location of the zipped root file fine? the title says "[BOOT] Wifi-Only Charge Light Off".

I only see one problem, you have recovery before boot.img. If you flash the recovery, without a rooted boot.img and happen to boot into honeycomb, it will erase your recovery and load stock. So you can remove /system/etc/install-recovery.sh and /system/recovery-from-boot.p or flash the boot.img BEFORE rebooting out of recovery.

You're right. I rooted 1st and flashed CWR later. I then used brd's method to update to 3.1, re-root and flash the new bootloader and kernel. So there is a step missing after Step 3. I'm sorry, I don't remember exactly how to do this from HC 3.1. (meaning what files to use) as I was on HC 3.0 at the time.

Yes it will. Read 3.4 again, it will do factory reset.
The root file may vary from case to case, but the procedure is the same AFAIK. I used the one that "charge light off"... There are probably others too.

Instructions are good to go. Just make sure that you don't reboot after flashing recovery, and before flashing boot image. If you do, by mistake, no harm done. You will just have to flash recovery again.

Tnx . Very help full .

I don't know but ROM Manager just isn't budging showing any signs of root... or Superuser (+Elite)... or MarketEnabler...
I don't know, I'm kinda lost here. Let me retry (for the tenth time).

Try again, and remember that timing (3 seconds) are key to success ...

I'll retry being more precise. I do get into Recovery and I flash the file mentioned. It seems it flashes correctly but when I boot into the OS, there's no signs of root anywhere.
I'll update in a few. Thanks!

Huawei Ascend P1/U9200 Root

This method is tested by me and it worked perfectly. With this guide you will be able to root your U9200 with b113 and b115(android 4.0 and 4.0.3).
I am not responsible for any data loss or bricked devices! You do it on your own risk!
1) Download this zip. The password is: ccc333
2) Extract the zip to your desktop.
3) Download Android SDK Tools from here and install the packages.
4) Plug your Ascend P1 to the PC.
5) Make sure that USB Debugging is checked (Settings -> Developer options -> USB debugging)!
6) Open "b113_b115-root_u9200---__[Nixing]" from your desktop.
7) Run "hwadb.exe".
8) Run "ubl.exe", click ROOT - this should root your device without restart and any problem, check if the Superuser icon has appeared.
After the device is rooted you will need to install recovery.
I used Geno's Recovery - run "Onekey_ROM_Ascendp1.exe" from the zip and the tool will install it.
From this recovery you can flash whatever you want w/o any problems! It's a little bit sad that it is in chinese but oh well...
I will attach a picture of the same recovery but in english so you can see what you are actually doing.
Good luck!

Hi.
When i try run "Onekey_ROM_Ascendp1.exe" i got stuck on reboot stage. Telephone just show Huawei Ascend. BTW Win 7 can't find driver for Blaze. I tried reboot manually with pressed power+volum up keys and recover update.zip. But recovery cant pass signature verification. :crying:

You can try this to install the recovery image onto the phone without the custom rom.
1. Download Android Control here (mirror) or here (XDA thread) and extract to a folder on your hard drive root (eg. c:\AndroidControl)
2. Download the Recovery image - recovery-new.img (the one included in Onekey) or recovery-off.img (the one that Onekey is based on)
Note: As far as I know, they are both Chinese language but based on ClockWorkMod so should be easy enough to navigate around. Edit: Though judging from the picture above then they may not be Chinese lol
3. Put whichever image you choose into the AndroidControl folder ready to be flashed over.
4. Make sure USB Debugging is enabled on your phone and then switch it off. Hold volume down and power key (I think lol) to boot into download mode (phone should boot to logo and then stop) then plug it into your PC.
5. Open a command prompt and navigate to your Android Control folder, run the following command -
fastboot flash recovery recovery-new.img
or
fastboot flash recovery recovery-off.img
depending which one you chose.
6. Once finished type - 'fastboot reboot' to reboot your phone.
7. Turn off your phone once rebooted and then hold the volume up and power keys to boot into recovery, if its in Chinese you've been successful

I am curious how you install some ROM as .zip file, when all original updates from Huawei have .app as extension.....

In my case it after step 5) it works a little bit different.
When run "Onekey_ROM_Ascendp1.exe" and stuck on reboot stage (just show Huawei Ascend), then you must install a driver for Blaze device manually, you can choose the standard "Android Adapter ADB interface" for this (it works in my case), after intalling the driver Onekey_ROM will resume and install only the recovery image and you phone is showing the Chinese recovery menu choose your "update.zip" or "gapps-signed.zip" from SD-card and it wil be installed (update.zip means your desired firmware).
It seems that the firmware in the Onekey_ROM_Ascendp1 tool will not be placed on the SD-card but in Local Storage, so it will not be installed, therefor put the "gapps-signed.zip" or "update.zip" before flashing on the SD-card so you can select it in Chinese recovery.
I only installed the gapps with original firmware B115 on the phone and all gapps are working.

Hi people,
I'm sorry for this little off topic but I don't know where to find other Huawei Ascend P1's users.
I would like to buy this device but before I would like to know if this device is going fine.
In particular way: how is the in call audio quality? Is it missing calls (like other Huawei device U8800 Pro)? How is the Network (GSM and/or UMTS-3G) quality?
Is the price balanced to the overall quality of the device? I just know that the Huawei Ascend P1 is able to record amazing video and the audio quality is really incredible, but the "phone" function, how is it?
Sorry for the off topic.
It's a great news that I can root the device, so probably at 99% I will buy it after reading your comments.
Thank you in advance,
regards,
kalo

Hey, I'm very pleased with my U9200, don't know about the others but everything works fine here. The device's default ROM was working perfect, I managed to root it and eventually changed to MIUI ROM. But yeah, the U9200 is a really good smartphone if you ask me. There are still not enough apps and tweaks for it etc.

Download Mode
Hey,
is there any trick to get into Download Mode/Fastboot?
Should I press both at the same time? When do I release them..
With Vol. Down + Power Key i don't get into Download Mode..
I just managed to get there once, but I don't remenber how I did it.
And by the way. When I press Vol.Up und Power, I get to the android recovery, stock. where I can do a wipe or apply a update from sdcard.
Pease let me known
jensema
EDIT:
Got it. Hold VOL. Down and then Plug in USB Cable.
Phone in Download Mode.
Now I need the right drivers.
Phone shows a "Blaze"
Can someone tell me which driver to use.
thanks
2.EDIT: Got it. Under Win7 , installing Hi Suite, then change Driver for "Blaze" to Android ADB Interface.
Fastboot working!

[GUIDE] Huawei Ascend P1 U9200 AIO

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. Downloads 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: https://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 instructions. 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 unuseful stuff) Place the .zip on the sd-card. Place language enabler.zip on the sd-card as well
→ Install a TWRP v2.4.4.0 recovery
→ Boot into recovery. Install GAPPS.zip. Install language enabler .zip as well
→ 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 superuser 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 unuseful 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!​

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/4.2.x). Make sure you pick the right one! (Links in download section). I recommend OpenGapps Pico. Heavier GAPPS will make your device much slower.
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 recommended 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. Editing 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 warranty!
- 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 (LineageOS 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 warranty. If the phone's hardware misbehave in any way you should contact Huawei or the store you bought it from.

You rooted before flashing GAPPS?

The "power bar"
I flashed B229 to a U9200, it had originally B103 which had been updated to 105. manually edited the build to B226 before updating with cwm. Everything is working fine no problems. Only couple of things are missing. The "power bar" which i use to control wifi, BT etc. power on and off in the notification menu (or what ever it is called, the menu that appears when swiping down from the upper edge) is missing and it is quite handy and I'm used to it. Other is the missing boot animation which i knew will be missing after update but did not care about that originally since other bigger issues in the B10x FWs forced me to update to B229. But if easy to apply and anyone knows the way to restore the animation (restore the looks as much "stock" as possible) i would appreciate. But the "power bar" would be very important, anyone know how to restore that? I have messed around with Android a bit and have installed and used custom ROMs and rooted several phones so using the basic root / fastboot / adb functions is no problem even though I'm no Android/Linux expert.
Thanks in advance for your help!
And thank you Olav for the very nice compilation thread for U9200.

Check in the Display settings if the "Notification settings" option is checked. See screenshot from the B226 ROM attached. I hope it's still there?

Boot animation can changed with the AIO flasher tool.

Hello,
I own an huawei u9200
I would like to flash the B229 ROM on my device running B102.
I find this thread very interesting however I have a problem at the very first step.
I can't install fastboot usb drivers
I've been trying to follow the guide you linked at the top of your post, I had a slight issue with ADB Drivers as well,
I could not make those Google USB Drivers downloaded through Android SDK work, I would get the error telling me those drivers are not developed to work with windows x64. But after checking with the command prompt, it turns out that the drivers I needed were already installed and the device is detected as ADB Device.
Back on my current issue:
I understand that I have to shut down my phone and switch it on while pressing both volume up and volume down and after turning it on, I have to plug it to the computer through USB cable. My phone does turn on in download mode, however when I connect it to the USB my computer doesn't detect anything.
Is the screen I am getting the right screen or should I switch the phone on with a different shortcut?
How do I get my computer to detect my phone when I switch it on with the volume+&- buttons?
Which are the correct fastboot drivers to install and where can I download them?
I hope to receive assistance as soon as possible.
Thank you.
EDIT:
I've managed to reboot correctly by using ADB command prompt (typing ADB reboot fastboot)
Now, I'm trying to root and in the command prompt I get this error:
"cannot load 'cwm_touch_recovery_viva_beta.img': No error"
EDIT:
Supersu installed.
Now when attempting to edit the build.prop I get a error message
I check the Concole and I see "Remount failed: Operation not permitted
But I granted root access when prompted. Any Idea?
EDIT:
Tried 39 times until I got it successfully.
And don't ask me how. It's beyond me.
Checked About and version is good.
Now rebooted and "Version list verify fail!"
WHY?
I've checked the build.prop and it is flashed,
I've flashed the 229recovery.img
I reboot and it gives me "Version list verify fail!"
What could have I done wrong?

Try with the build.prop from b226, avaible here: http://openbuildprop.scheffsblend.com/mfg/Huawei (copy -> paste into notepad, save as build.prop)

Ok, this makes sense, it probably wouldn't like to update to a version which is already installed.
This wasn't clear on the tutorial, thanks for the hint.
I'm trying now
EDIT:
Nope, still "Version list verify fail!"
Even though I checked in the "About" and the version shown is B226, which means the .prop was correctly flashed.
So what could the problem be?
EDIT:
Should I also try flashing the B226 recovery?
Do you have a link for any download page?
Can I flash it directly through CWM? CWM wants a root://Update.zip can I put my UPDATE.APP into a zip archive and flash it or does it work differently?

People have had problems updating to B229 with the build.prop i extracted from the B229 fw.
There is simply a little difference at this line:
Code:
ro.build.display.id=V100R001C00B229
It should be:
Code:
ro.build.display.id=U9200-V100R001C00B229
Build.prop from all earlier firmwares (Exept B226) including EmUI betas and stables have the "U9200-"-part before product version on this line.
This is a mistake by Huawei, not me :good:
Updated the FlashPack for B229, new link from mega in first post!

Hi there, let's go step by step without "shortcuts" that are typically working on PC/WIn.
1. Unlock bootloader of your phone at HTCdev[dot]com [replace 'dot' with . - sorry for confusion I haven't earned reputation to post external links yet]. All necessary tools (fastboot) will be provided to download during process as well as necessary instructions. You need Windows/Linux or OS X computer to complete this step.
2. Download custom recovery .img file and save it to same directory you have fastboot files (e.g. from step 1) on you computer
3. Start phone in fastboot mode (mind fast boot option in Power settings must be unchecked if you using VolDown [-] start option (not necessary if you use adb reboot bootloader). Battery must be charged over 10% (I suggest 30% to stay secure); connect to computer (phone shall display Fastboot USB)
4. Navigate command/terminal window on your computer to location of recovery image file from step 2 (fastboot files must be there or have a correct path specified).
5. On computer terminal window run command: fastboot flash recovery filename_of_recovery.img . Red section must be exact custom recovery file name.
6. You'll get some communication in terminal. If completed OK will be among them, if failure, there will be FAIL with description of reason (e.g. low_power). If only "waitng for device" dislays, check connection with phone.
7. Navigate phone to HBOOT, then select recovery. If recovery don't start, check step 1 and restart from step 3. If only icon with red ! appears, it means you have stock recovery installed. Please verify from step 1.
8. Once custom recovery is installed and working, use it to flash SuperSU or any other superuser app (must be flashable .zip to be applied). Install just 1 root application, to avoid problems. At this point, you may consider flashing busybox also if you plan extensive file modification, but it's not necessary for root. For any sake, clear cache befor restart.
9. Restart the phone - you shall view SuperSU application or any other superuses app you've flashed i step 8.
Hope now works.

1. Unlock bootloader of your phone at HTCdev[dot]com [replace 'dot' with . - sorry for confusion I haven't earned reputation to post external links yet]. All necessary tools (fastboot) will be provided to download during process as well as necessary instructions. You need Windows/Linux or OS X computer to complete this step.
2. Download custom recovery .img file and save it to same directory you have fastboot files (e.g. from step 1) on you computer
3. Start phone in fastboot mode (mind fast boot option in Power settings must be unchecked if you using VolDown [-] start option (not necessary if you use adb reboot bootloader). Battery must be charged over 10% (I suggest 30% to stay secure); connect to computer (phone shall display Fastboot USB)
4. Navigate command/terminal window on your computer to location of recovery image file from step 2 (fastboot files must be there or have a correct path specified).
5. On computer terminal window run command: fastboot flash recovery filename_of_recovery.img . Red section must be exact custom recovery file name.
6. You'll get some communication in terminal. If completed OK will be among them, if failure, there will be FAIL with description of reason (e.g. low_power). If only "waitng for device" dislays, check connection with phone.
7. Navigate phone to HBOOT, then select recovery. If recovery don't start, check step 1 and restart from step 3. If only icon with red ! appears, it means you have stock recovery installed. Please verify from step 1.
8. Once custom recovery is installed and working, use it to flash SuperSU or any other superuser app (must be flashable .zip to be applied). Install just 1 root application, to avoid problems. At this point, you may consider flashing busybox also if you plan extensive file modification, but it's not necessary for root. For any sake, clear cache befor restart.
9. Restart the phone - you shall view SuperSU application or any other superuses app you've flashed i step 8.
Hope now works.

Thanks for your answer, I have to say I properly unlocked the phone so I do not think there is a way I messed up with this step as when I start bootloader it clearly shows on the top of the screen ''UNLOCKED".
When I flashed recovery on my phone I had no errors prompted or any message of failure. The process went well until a success notification.
Now when I start my phone into bootloader I repeat, I clearly see that recovery has been installed but when I attempt to start it then I'll be almost instantly brought back to the bootloader screen... now I started to wonder if... if an update of android could cause this kind of issue? The point is my phone is using android 4.4.4 and not the factory version 4.4.2. I remember having updated my android version which was perhaps a mistake as this phone is not very old and I was planning to root it in the next days... Now I'm not expert just try to figure it out.
I tried different system to auto root via different apps, some using the PC some using directly the phone, I never get any success...

Ok, please try twrp from Original Android Development tread (it works for me, mind, I'd question it's stability) or Philz recovery (sorry, I found only Chinese, but it's for verivication only: h...ps://drive.google.com/file/d/0BygOvRquk4z8S05kRC1XMXdSbXM/view?usp=sharing - please adjust tt in address - rookie rules).
I'd suggest test running from Fastboot: fastboot boot custom_recovery.img - replace with actual file name from directory you're running terminal.
This shall verify if it's problem with recovery file or any remaining protection...

Hallo Friend!
I am about to test your guide. I think it is most decent among other guides on the net...
Could you please just tell me if it's gonna work on:
Android 6.0.1 MMB29M
MIUI 8.2.1.0 (MBCMIDL) Stable
kernel 3.10.84-perf-gfe86e7b
bootloader UNLOCKED
Is superSU by default included in the TWRP you gave? No need to download it additionally from somewhere?
What about warning about "dm-verity" on official TWRP website?
This device uses dm-verity!
This means that swiping to allow system modifications will prevent you from being able to boot if you are using the stock kernel. In order to bypass dm-verity's boot prevention, you will have to install a kernel that has dm-verity disabled in the fstab.

Should this be any concern that the phone will not boot up again? Should this be disabled first?
Is it better to use the TWRP version you provided (3.0.3.0? not listed on official TWRP website? why?) or the lastest 3.1.0.0?

Ok just two questions then, because I'm not sure what you can't understand. Please explain.
1) What Android, MIUI and kernel did you root?
2) Do you have SuperSu.zip in TWRP 3.0.3 by default? You didn't say anything in your guide about downloading it and from where + what version.

This twrp. Img it's for all the versions but only for mi max. Not the prime . This twrp doesn't contain superSU. If I remember correctly. But if on the TWRP contain the super su. Don't say yes. Just flash it like I saying on the guide. Maybe they upload a newest version. You can use the new. I think I put the official website . I will check it.

Ok thanks for the answer. Please check from where I download SuperSu - which version would be best.
Please tell me your Android, kernel and MIUI version that you rooted.

Waiting to tell me if everything went fine with the installation and the flashing

Hey, tried following Your guide to install a new rom last night. Great guide for noobs like me, but it may be worth renaming the thread to something like "How to flash whatever makes You happy on to Your Mi Max". These instructions seem to work fine regardless of what's being flashed. Great job, mate!

So I finally tried it and it was successful for me as well! But I used the latest version of TWRP (3.1.0) and SuperSu (2.79-20161205). Please add a point in your tutorial to upload SuperSU.zip to the phone first, because out of emotion, I forgot... So I flashed TWRP, booted it and then... ups... no SuperSu So I wanted to reboot the phone to upload SuperSU but since only SuperSU patches dm-verity (the thing I was afraid of the most - I told you before), my phone got into boot-loop and didn't want to start. So I just uploaded SuperSU to a memory card, entered Fastboot Mode again with key-combination, plugged the cable, typed "fastboot reboot-bootloader" command and was again in TWRP to flash SuperSu from my memory card.... ufff.
So I would reedit it a bit:
0. Copy SuperSU.zip to the phone/memory card!
1. Go to Settings-About phone-Find the MIUI VERSION, and tap on it for 5-10 times.
2. Go back to settings, sellect adittional settings. click on Developer options, and select enable
3. Find the option USB Debugging and enable it.
4. Download the TWRP recovery from the link
5. rename the file to 'recovery.img'
6. Move the image to the same file where the ADB was installed ( it should be on Computer-> C: -> Adb )
7. Open the adb folder
8. Press and hold the shift key and right click in the folder
9. click on the option "Open command window here"
10. Boot your device on fastboot mode by turning it off, pressing Power and the Volume Down buttons together, and then connect it with your computer
11. First type this command "fastboot devices" to check if your device is into fastboot mode
12. Enter the command "fastboot flash recovery recovery.img"
13. Enter the command "fastboot boot recovery.img" - the phone will get disconnected from your PC automatically
14. Your phone is now in TWRP recovery mode (it takes about 30-60 seconds before FastBoot screen switches into TWRP - wait patiently)
15. select Install Zip and click on 'SuperSu.zip'
16. corfirm the flash
17. reboot your device
18. DONT PANIC IF YOU DEVICE WONT TURN ON. Sometimes need to wait 10-20 secs.

Hey, I just got connected with WiFi and new MIUI 8.2.3.0 MBCMIDL wants to be installed, although the phone is rooted with bootloader unlocked. Is it safe to apply the update? Is it goona remove root so that I have to go over the process again?

So I tried the update. First time it said it failed, second time it downloaded the whole ROM after which it rebooted device and TWRP started doing "something" - I don't know what. After that the phone didn't want to boot, and what's even better didn't want to run recovery (TWRP), instead it went into fastboot. What I had to do was to use MiPhoneDrivers from this topic: https://forum.xda-developers.com/mi-max/how-to/guide-install-global-miui8-root-t3435594 (including MiFlash 2015, because 2016 version didn't want to work properly on my PC) and follow the instruction from official MIUI website to flash from scratch the new ROM MIUI 8.2.3.0 which I did. After that my phone was alive again. I installed TWRP and rooted the phone again. Now I've got MIUI 8.2.30 rooted. :] End of the story so far. My settings left untouched - icons, wallpaper etc. So that would be the way to update MIUI if they prepare a new one.

Is there anyway to root the phone without connecting it to pc?

Thanks for saving me the trouble.
Can someone help with a better method of applying updates?
Will downloading the zip (1.4GB approx) and flashing via TWRP help?
