You need to flash again the stock rom, the factory reset won't work.
You can found it here http://forum.xda-developers.com/showpost.php?p=51090040&postcount=2 and flashing through fastboot
I don't know what frameworks-res.apk you used, but maybe you forgot set the right permissions, or maybe you took the files for other device.
DL VN 7
Is there some tutorial for flash with fastboot??, i never did it, and i don't want destroy some other..

sorry for the late reply.
In the dell's opensource page there aren't files for the 3730 (i don't know why)
but, may be i'm wrong, there aren't tutorials for flashing in fastboot, i only found posts in xda's dell venue general forum.
i'll write here a guide if you still without founding a tutorial and for any others if found this post
you need:
intel usb drivershttps://software.intel.com/en-us/android/articles/intel-usb-driver-for-android-devices , read the instruccions if you are in windows 8 (i'm on win7 so i cannot tell you if is the same method or not)
The tools for fastboot (there are in a folder called "google") is a little confused so better download @social-design-concepts miKIT_BATCH HERE (before continue let's say thanks to @social-design-concepts for his useful tool that also works for root ),extract wherever you want in your computer.
the files to flash HEREdownload the package for your device and once donwloaded extract where you want in your computer
NOW FOR FLASH
1.-
Install the intel android usb drivers, if you did this before, skip
2.-
Open the myKIT_BATCH folder and run the "runme.bat" file, then type ACCEPT, after that type 2 and press "enter" (the option 1 is for update the driver, in myKIT_BATCH's post 1 is explained) the font should be red.
3.-
boot into fastboot (press button "power" and button "volume down" at the same time) your tablet's screen will display a blue android with gears inside and below it the "droidboot" text and your device info in your device's top|left screen corner , if yes connect your tablet to pc to recognize it (if is the first time).
4.- Open a command window
after the pc recognizes your tablet unplug and plug again the usb cable, should be faster the recognicion this time.
Then in myKIT_BATCH window press "enter" to refresh, the font will become green and will display your device's info, if is going fine in the window type 4 and press "enter", will appear another window.
IF everything still going fine in the new command window type:
Code:
fastboot devices
will display your device's info
5.- let's start with fastboot
BUT first ENSURE THAT THE BATTERY HAVE A CONSIDERABLE CHARGED LEVEL
Unfortunately i don't know what happens if the tablet power off when flashing and if fastboot will work fine after so check your battery charge first
i need to tell you that the 1-4 steps are the most difficult steps (you should have at this time the rom downloaded and extracted only extract the downloaded package (the .7z file)
after this explained so let's start.
5.1.- WIPING
fastboot have some wipe commands so i will explain the 2 that i used:
Code:
fastboot erase cache
This code explains itself, you can try this code to verify that your device is connected
Code:
fastboot erase data
easy to use but powerful, this will erase app's data and also your internal storage (the 11GB that the tablet have to store files), unfortunately i used this without know and i lost 8GB of files
5.2.- NOW TO FLASH
works almost equal with the wipping commands so it's easy to explain.
let's start with system
for a easy explain you ned to open a window where the rom's files are stored in your pc and in the command shell type "fastboot flash system" and after that drag the system file (system.img.tar.gz) to the command window after dragging the file will appear in the command window the full path of the file
I.E i have a dell venue 8 3830 and i want to flash the jellybean 4.2.2 stock rom so i downloaded the Venue_8_WiFi_JB4.2.2v1.42_FLASHPKG and extract this in F:\VENUE 8 3830\stock rom folder so after type the command and drag and drop the system file in my command window will display this:
Code:
fastboot flash system F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.system.img.gz
after this the command press "enter" and you don't need to do nothing (maybe your window will turn off and maybe you try to turn on but will keep off, don't worry only let fininsh) the fastboot program will start to prepare the file for upload to the tablet and after that to flash.
this will finish in 1-2 minutes.
NOW THE BOOT.IMG
is the same way than system but faster.
after finishing flashing system (when the window diplays the elapsed time) type: "fastboot flash boot" and drag and drop the boot.img file in the command window
I.E. in my device will be like this:
Code:
fastboot flash boot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.boot.img
press "enter" and will do the same like system prepare,upload and flash the file.
there are in the download package more file but only with BOOT and SYSTEM flashed your tab should boot
but if you want to flash the other images you need to type
for recovery:
Code:
fastboot flash recovery F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.recovery.img
and for fastboot:
Code:
fastboot flash fastboot F:\VENUE 3830\stock rom\VENUE_8_WIFI_JB4.2.2v1.42.fastboot.img
for my example, for you will be change a little
thanks to all who read and understand this guide, bad english
you are free to comment this if i mistake

unfortunately i don't have a computer with windows 10 so i can't solve easily.
i found this googling, so with a little of faith :fingers-crossed: , is the same error than yours http://android.stackexchange.com/questions/118823/how-to-install-adb-drivers-on-windows-10-opoit's for the OPO, but is about the same "intalling adb driver", so could work
in a dessesperate attempt, you can use the update usb drivers in "myKit_BATCH" typing "1" after typyng "ACCEPT"
I fixed it with 15 seconds installer!, i gng try to fix tablet
But i found next problem, after connect tab to PC, just UNKNOWN, and tab is not showing in mykit

Ahh that's add driver not recognize your tablet, I suppose that you connect in fastboot mode,
Try using the option of update the adb driver in Mykit_BATCH, you don't lose nothing trying.
Other option is trying the dell's method http://opensource.dell.com/releases/Venue_8_3830_CloverTrail_plus/developer-edition/Download the pdf file and read the instructions from page 2 to page 9 if still not working
here is the sdk tools for windows that the pdf wants
I downloaded SDK tools, i installed Google usb driver, because it say not installed, when it was installing it said: Disable adb driver, ineffectual, error code -1, but after install it work good, so i will test with this, when no i will try another way, that u wrote here
Finally, tried method, no work, finally, update ADB no working for me, cuz installation always fail, next one DELL method, working but i found problem, dell wrote update driver via google extra with codes, BUT
My first code: USB\VID_413C&PID_B119&REV_????, ????, i think there is something wrong
My second code: USB\VID_413C&PID_B119, i think this one is alright, but then up
Finally with dell next page i'm in!, but my kit no working, in every command shut down, so i using windows cmd, it working too
Mhm bruh, no i'm in flash system, sending 'system' awesome, but it's more than 2 minutes , when it will work, omg u r awesome
Bruh, yay, i did it, thq u r master <33

Are you telling that the dell method works?
The good new is that your tablet is back (with some problems in the way but work, ). after all now you know how to flash through fastboot. If anyelse goes wrong again, you know what to do
NOTE: Maybe your want to replace the framework-res again, but only will work if is for your device. So i recomend that you modify your stock framework-res by yourself (you can use images or xmls from other sources to your framework-res, this should be safer) using apktool manually or a program (there are some of them in xda, choose your favorite )
Yay 50% of dell method worked, just 50% because Dell have tutorial for setting up ADB service, after it i used your tut, thanks, and believe me i will not test it NEVER again.

My tab started giving al kind of errors on internal apps and stuff so i shut it down and now it is in reboot loop.
I can get it into odin download mode or fastboot mode. But i cannot see it with adb or fastboot (it doesent show up when using adb devices or fastboot devices.
i can use odin to do a pda flash but outcome is stil the same.
also did nvflash from Retail 3.1 CWM Recovery, Root & full back up!
al goes fine but after that still no adb reboot recovery or adb devices

Here's what you do.
Download the file linked below
Download ODIN attached below
Once both are downloaded, extract PDA_SIGNED_P7105.tar
Boot your tablet into ODIN and plug it into your PC
Open the ODIN program on your PC and check the box next to PDA
Click the PDA button and navigate to the file you downloaded earlier
Press Start and let it flash
Once it is done, it will still boot loop.
You need to go into recovery (It will now be the default recovery) and wipe data/factory reset only.
Reboot and it should load up, however you will be on 3.0.1.
You can get back to 3.1 by rooting and installing recovery again or by using the update feature in the tablet's settings.
Good luck!

Hi All,
I am done the ODIN step, but it still in bootloop mode. I dont know how to do with the Fastboot recover mode. I tried with my Windows 7 and it can't recognized my fastboot driver and stay in the <waiting for device>. Is there any solution for me. Thank you so much.

Hello, I have also followed these directions however I am having issues rebooting into recovery using adb.
When I execute adb devices no devices are found.
Any additional help would be appreciated. Thanks
UPDATE:
Success!! I was able to correct the boot loop problem by installing fastboot on a linux machine and running sudo fastboot -w. Also my tablet was in fastboot mode (Power + Volume down, then Select the usb symbol).
Instructions for installing fastboot were found here http://forum.xda-developers.com/showpost.php?p=14675422&postcount=2
boot looping SOLVED! Honeycomb 3.1 google i/o galaxy tab 10.1
[IO TAB] Boot looping? Try this to get your tab back...
I had an issue with my IO 10.1 Tab boot looping. I imagine that this would work for retail as well but have not tried it.
This process will factory reset your device.
You will need fastboot and recovery.img to boot into recovery in order to perform a factory reset.
Fastboot & Stock IO recovery comes from this post as an attachment at the bottom.
You need adb to continue (windows).
1. Extract files to where adb resides (platform-tools folder in android SDk main folder) e.g
C:\Program Files\Android\android-sdk\platform-tools .
2. Plug your tab in to a power source and then hold down the power button until it shuts down. Wait until the tab displays the charging battery.
3. Press and hold the volume down (left button in landscape) and power buttons until the usb and odin icons show up. Volume down to move left and volume up to select the usb logo. Now you should be in fastboot. Plug the usb into your computer.
4. Time to fire up adb!
Start / run / cmd , cd\,
Than, cd to your platform-tools folder or wherever your adb is at. (should be in platform-tools inside of android-sdk-windows)
5. In cmd type "adb start-server" without quotes to start adb. All comands should exclude quotes.
6. Type "fastboot devices" your device serial should appear!If not:
Edit the “<PATH TO ANDROID SDK>\extras\google\usb_driver\android_winusb.inf” file and copy/paste the following lines and add them to the [Google.NTx86] section (for 32bit Windows) and/or [Google.NTamd64] (for 64bit Windows).
NO Empty line above this set, though galaxy tab 10.1v but works for all variants!(tab detected as adb xxx device)
;Galaxy Tab 10.1v
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&REV_9999&MI_01
%CompositeAdbInterface% = USB_Install, USB\VID_04E8&PID_6860&MI_01
%SingleAdbInterface% = USB_Install, USB\VID_04E8&PID_6601
%SingleAdbInterface% = USB_Install, USB\VID_0955&PID_7000
;
Download the fastboot zip attached to this post (includes both Win and Linux version) and extract the files to your “<PATH TO ANDROID SDK>\platform-tools” folder
7. Now, type "fastboot boot recovery.img"
8. Now you should boot into recovery. For "adb command lines" to work boot with clockworkmod recovery img (Command and files here: http://droidbasement.com/db-blog/?p=2032)
If you want to try other stuff like push a system restore, kernel or whatever, now you can. If you fail at it, you can always repeat the steps leading up to this point to get back to recovery.
9. Time to just get the tab back! Select "wipe data/factory reset" and confirm, clear cache.
10. After that is done select "reboot device".
Credits to JASKRU from rootwiki, with some additions and modifications extracted from different sources!
for rooting the tab install the zip file from this post in recovery mode (loading recovery.img from fastboot):
http://droidbasement.com/db-blog/?p=2054
P.S don't reboot into recovery with adb command "adb reboot recovery" as it doesn't work, correct way is with fastboot command as mentioned in step 7!
'fastboot' is not recognized as an internal or external command,
operable program or batch file.
FIRST STEP: add the attached fastboot files into the container folder of adb (in sdk folder)
This is mine:
C:\Program Files\Android\android-sdk\platform-tools
of course I did that and mine is in the same folder as yours
I get to step six and thats when it gives me the error
E:\android-sdk-windows\platform-tools>fast boot devices
'fast' is not recognized as an internal or external command,
operable program or batch file.
also when I go to the left instead of odin this is my pic (in attachment)
NOW if I hit the power button and the right on in landscape mode I do get the android system recovery options says Android System Recovery <3e> (pic attached)
I have tried wiping date clearing cache as far as fastboot goes it still doesnt let me in fastboot eventhough im not sure at this point what fastboot even is
I finally got CWM 4.0.0.4 on it but now what because somehow im on 3.0.1 on my tab it wont charge and idk what to do
These steps were tested on 3.1.can you update your firmware from kies or on device?fastboot is needed to boot into the recovery image as in your pic which you already have managed being in older firmware.
E:\android-sdk-windows\platform-tools>fast boot devices
I believe something is still wrong, did you extract the contents of zip file in the platform-tools or the complete folder?Second, how was your tab once in fastboot recongnized by windows it should be as an adb. Device and not fastboot. Third, try manually installing the driver from extras folder, google, usb in android sdk. Last is your system 64bit or 32bit as the modification in inf file should be made accordingly. The only issue is driver or fastboot exe not being in adb folder.
Adding, once in recovery as in the pic, try command adb devices and let know if your device is detected hence you can push a restore fileto your device and reboot or push original recovery.zip file and apply it from sdcard (internal memory).
Last try odin option and flash firmware as tar file mentioned in this forum, try the bootloop or blank screen threads.
tried this route but it cannot find my device via ADB - used the PDANet driver - note i did not get a driver in the extras folder
ideas?

solved my problem -
first fastboot.exe is located in the android-sdk\tools directory. i copied it to my android-sdk\platform-tools directory
Then i get into the tablet's fastboot mode (holding down power + volume down, then select the USB icon) i plug in the cable to my PC's USB, then go to device manager and you should see a fastboot device with an exclamation mark. right click on this and select update driver then navigate to android-sdk\extras\google\usb_driver directory and select android_winusb.inf - it should now install the driver
open up a cmd window and follow the instructions highlighted above starting at step 7

IN Short, follow the steps in my previous post from 1st till end! Flashing the bootloader file from my thread in development section, is easiest way. Replacing fastboot with recovery option in bootscreen solves many issues for non-developers!
yes and i should add your method was very effective ! thanks
what threw me off initially was not finding the fastboot.exe which was in a different folder and the usbdriver - which needed to be installed separately and can be found by launching SDK manager, selecting Available packages-Third-party Add ons-Google Inc - Google USB Driver Package revision 4

Samsung Galaxy Tab 10.1 boot loop
Edit: *Fixed!* Ok, so here is my advice to all you other noobs who bricked your tablet, be AWARE that your tablet actually is conscious, it chooses when it wants to work. Just do everything it says on here, all the fixes I have listed, reboot a bunch of times, yell at it, and when you cry a true tear of pain and remorse, and it splashes down on the surface, it will recognize this and all of a sudden work. Booted to 3.0.1 and going to update, that all that is holy.
Hi Guys, I am having the same problem and need some expert advice please, I have a Samsung Galaxy Tab 10.1 with Android Honeycomb 3.1, running Windows XP Pro SP3
I've gone over every solution to this problem on xda over two days and none have worked for me, either that or i'm not doing it correctly.
I successfully rooted my Tab a few days ago, then tried to install a 'boosted' theme and everything is messed up now. When I boot it just hangs on the samsung loading screen, and it reboots to the same screen.
I have tried wiping data/factory reset in cwm
I have tried wiping cache partition
I have tried running Odin through downloading mode
I have adb and fastboot installed on my computer
I have Samsung Android adb interface driver in Device Manager
I have PDAnet installed
When I boot holding the volume down and power button to get the two options, the only two options I have are the Odin Downloading green guy on the right, and an icon with a box and an arrow coming out of it that takes me to CWM on the left.
So I cannot choose fastboot mode on the Tab, when I try to run 'fastboot flash system new.img' through cmd.exe it just says < waiting for device >
I"m a total noob to this and should have left well enough alone when I successfully rooted it, i'm sure I must be just missing a small step, if I could get a bit of guidance it would be greatly appreciated, thanks.

Edit: If anyone has a link to the stock ROM for the Ascend G7, please let me know. I would love to make a custom ROM that doesn't take up 98% of all resources 99% of the time.
Hello everyone.
Before I get started, here is everything you need to know about this post.
- This root works as of June 29, 2015
- This is a rooting process for the Huawei Ascend G7
- I did not make this, so please consider supporting all mentioned sources
- I am a new user to XDA, but I've been developing for over a decade. I will regularly check this post if enough people who view it have questions
There are two parts to this process.
First, we unlock the bootloader
Second, we flash a recovery, and subsequently, SU (root)
Let's get started. This will take at least 16 hours. User interaction 5 minutes, and about a 16 hour wait for an email response from Huawei.
Also, I have a new account, so I cannot post links. So please bear with me. I will upload photos in as best order as I can.
Before we get started, please note that your phone will factory reset in this process.
First thing's first. The Ascend G7 requires an unlocked bootloader, before any root can take place. This is obviously temporary, until someone finds a circumvention. But for now, this is how this needs to be done.
Send an email to [email protected], with this format:
Dear Sir/Madam
Please may I request the bootloader unlock code for my Huawei Ascend G7?
Here are some Details:
Serial Number: (Found under Settings --> About phone --> Status)
IMEI: (Found under Settings --> About phone --> Status)
Baseband version: (Found under Settings --> About phone)
Please could you send me the code directly, as I cannot access the product ID on my device.
Thank You
Your name
This part is important. Sometimes, they do not even reply to your email(s). It is recommended - nay, required - for you to put "URGENT" in the subject field of the email. Something along the lines of "URGENT Request Bootloader Unlock Code." It would also be best if you mark your email as urgent/high priority, as well.
Meanwhile, while you wait for the email from them with your unlock code, (expect it to arrive the day after), download the Android SDK and the Java JDK, if you haven't already. What you need most are the SDK tools, which you can also download by typing in "SDK tools android" in Google and finding a download for the stand-alone tools.
Make sure Android Studio is updated, if you already have it. To make sure you have everything you need, open up command prompt in platform-tools, by holding shift and right clicking somewhere on the white, in the folder, (explained in attached picture).
Then, plug in your phone. Make sure USB debugging is enabled. To do so, go to Settings --> About phone --> Tap "Build Number" 7 times in a row. Then go back, and you will see "Developer options." Click on that, and enable USB debugging. Also, this optional, but I like to enable the "Stay Awake" function.
Make sure to accept any prompts that your phone will ask.
Then, go to the command prompt and type in "adb devices" without the quotations.
If you've done everything correctly so far, you should see something similar to the attached command prompt image file.
If everything checks out, let's proceed. If not, post below, and I, or fellow XDA users, will help you out.
Proceed to type in, "adb reboot bootloader" without the quotations, into the command prompt window that you opened. Your Ascend G7 should reboot into fastboot, where you will see something like the attached picture below, of the bootloader screen.
Except, it will say Phone Locked instead of Phone Unlocked.
Now, go back to your command line, and type in "fastboot reboot," to have access to your phone and its functions, while you wait for the email from Huawei.
`````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````
Everything below this line should be done AFTER receiving a reply email from Huawei, with your unlock code.
Now, download the "PHILZ-TOUCH-6.rar" file. I cannot attach it here because it exceed file size limit. No virus, no surveys, here's the link, https/goo.gl/sxPv7I. Just add a colon and a forward slash after https. It is not a virus, in case your firewall or antivirus software brings up red flags. I will post the whole ZIP that I've downloaded from another website. There's a bunch of redundant elements in the folder, but just in case you know what you're doing and might need the tools, I'll keep them there. But all you will need are 2 things from the folder. They're mentioned next.
Go to where you extracted PHILZ to, and hold shift and right click and open a command window in that directory, and type in "adb devices" one more time to make sure your device is listed and connected. Then, type in "adb reboot bootloader," give it a second, and then when fastboot loads up, type in,
fastboot oem unlock 123456789123
Replace "123456789123" with the unlock code provided to you from the Huawei email. Give it a second, and then you should be good. It should now say "Phone Unlocked" in red. Now, type
"fastboot reboot"
in the command line (that was opened in the PHILZ folder), without quotations. Then type,
adb reboot bootloader, one more time, and then,
Navigate to the PHILZ folder, and run "install-windows.bat" as administrator, if using Windows.
If using Linux, run "Install-Linux.sh," and if using a Mac, run "Install-Max.sh"
Now, in CMD type,
fastboot boot recovery.img
Then, again type in
fastboot reboot
Your phone will reboot.
`````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````````
Aaaaaaand that's it! You should now be rooted. I recommend going to play store, and downloading a Root Checker to ascertain root access.
The last picture, where it says I have root access now, is a program called Root Genius. It's a one click tool to root any android device - obviously except the Ascend G7, (knowing my luck). But it does work as a root checker as well, if you want to ascertain root access. You can also download Root Checker from the play store; works more or less the same way.
Any questions, feel free to ask. Re-reading this, I could see if the instructions bring confusion to some. I will be glad to clarify any questions.
Works
Root confirmed G7-L01
some point that I did not understood
dear wertywhy,
your guide is really well done, but there are some points not clear to me
1) open up command prompt in platform-tools
what is platform-tools? A specific folder? I was not able to find it
2) if I open the command prompt from any forlder using the shift+right button as you said and then write adb devices I get this message:
'adb' is not recognized as in internal or external command operable progrma or batch file. What should I do?
3) when I connect the phone by usb cable, should I do something more (like enabling device file manager, pc suite or other options) or just connect it in charge only mode?
thank you for your time!
and... by the way, I'm really impressed that I got the anwer from Huawei with the code, that's really cool! Thank you!!
---------- Post added at 04:09 PM ---------- Previous post was at 03:19 PM ----------
I found the platform-tools folder, now if I type adb devices from a prompt open from that folder I don't get the error message anymore, but I get nothing, just the flashing prompt line (the huawei phone is on and usb connected to pc)
dear wertywhy,
your guide is really well done, but there are some points not clear to me
1) I had to install hi-suite to let the command adb work (before that adb was not finding the phone)
2) the file names of adb inside PHILZ_TOUCH is adb-windows and fastboot is fastboot-windows
3) when I input the command adb-windows devices inside the prompt inside the PHILZ folder the result is device offline, I could unlock the phone running the command from platform-tools directory (phone is unlocked now) but I can't run the command to root the phone until I have this "device offline"
Point 1 and 2 are not problem, just something that happened to me, but point 3 is stopping me, any idea how to solve point 3?

I'm having the same problem. I tried toggling usb debugging off and back on, tried another usb port and another PC (WIN 7 and 8) but none of that helped.

Hi Frank,
Let's troubleshoot,
If it lists your device as offline, open up cmd (Run --> cmd), and type in,
taskkill /f /im adb.exe
Then, restart your G7; when it boots up, turn off and then on USB debugging, then find PHILZ, and retry point 3. If device is still offline, please let me know. The issue sounds like it's within the phone, not within ADB.
Alternatively, if that doesn't work, please delete PHILZ off your computer, and wherever it says "PHILZ" in my guide, replace it with the attached folder, (attached with this reply).
Cheers
PS, please make sure to check that your phone is not only in USB debugging mode, but that you've approved/allowed your computer access to your phone, (a prompt will show up on the Ascend G7 that asks you whether or not you trust your PC). And also make sure your phone isn't just set to "charge" when plugged in - activate/select MTP when you connect your phone to computer.

Please refer to my reply to Frankleoni below.
Thank you for replying chy_vak,
I tried your solution in both the PHILZ folder and the new folder you attached. The device shows offline in both of them. However in the build-tools folder it shows online. The command line taskkill /f /im adb.exe terminated adb but the device still shows offline. I did everything in the exact order you wrote.

search Kings Root via Google Chrome, install it and run it Easy and without chat with Huawei support
Kingroot Works like a charm !
@chy_vak, Thank you for your Work. 1st Part works great. 2nd Part went wrong, i dunno why i`ve tried every thing. I hate this Kingroot think, don`t touch it you never will leave it.
I have connect my G7 because unlock works. When i use CMD from Adb Tool it is connected, when i use command prompt from Philz he cant see and find the mobile?? Something for you absolute clearly, isn`t for other. Sry cant do screenshot with notebook and Win 10. have fun
Another Working Method to Root Huawei Ascend G7-L01/L03
Greetings!
I got an Ascend G7 Recently and I needed to Root it as soon as I got it. That's why I kind of broke my head looking for the current methods to do it. I found this one very promising so I started working. I followed the steps that were given to us one by one. Everything was alright until I tried to install the Windos-Installer.bat as administrator, I tried to many ways to this method work, but as much as I tried, I couldn't go with it, that's why I started working for 11 hours until I got it. This Worked for me, and I want to share it with you.
Please read the following notes before you start by rooting your device:
-As usually, do it at your own risk, I'm not responsable of any brick, or issue that damaged your device.
-This Method is working great on Windows 10
-This Method is working at 04/08/2015
-This Method, was tried by me, the directions I give to you, are based on my work by rooting my device and my experience, the software and files included were made and posted by someone else including the person who wrote this post: http://forum.xda-developers.com/gen...-confirmed-t3125621/post61122491#post61122491
-You can find screenshots of the procedure below
-You will need a microSD
-I strongly recommend you to have at least 80% of battery to avoid risks of bricks
-------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Here begins the directions:
1.- As has been said, you will need to unlock your device bootloader in order to root your phone. So as they said, you will need to write an email to Huawei. The mail you will send should look like this:
To: [email protected],
[email protected]
Subject: (URGENT) Unlock Bootloader
Model: Huawei G7-L03/L01 (Depends on your version)
Serial Number: (The one that comes in your Huawei's box)
IMEI: (You can get it on your box or in the info included on Configuration->About the phone->State
Product ID: (You can get it by typing on the Dial the next code: *#*#1357946#*#*)
I appreciate your concern of reading this. Waiting for a response.
Sincerely: (Your name)
After a while (Could take between 15 minutes and 16 hours depending on their time) A Huawei worker will answer you something like this:
Dear Customer,
Thank you for supporting Huawei device. My working number is ****. Your unlock code :************** , please keeping your unlock code properly.Thank you!
Huawei Terminal Company limited
1.1.- (OPTIONAL) As we are going to unlock the bootloader, we are going to make a factory reset, so I strongly recomend you to make a backup with the official huawei backup app in order to restore our settings, apps, and files.
1.2.- Once Again, as has been said, you will need to download the whole Android suite (Android Studio) the last version, update your java version, and download the last drivers for your device (A good way to do the last is by installing the HiSuite of Huawei).
1.3.- You need to activate the debug mode. You can find it in: Configuration->Developer Options->USB Debug (If you dont have the Developer options enabled, you have to go to Configuration->About the phone->Compilation And tap this last one 7 times)
2.- Download the .rar a the end of the page and extract it where you want, includes everything we are going to need. [You must put the file ''superuser.zip'' on your microSD (In the root of the microSD)]. After Downloading it, you must open a cmd window, running it as administrator. After that you will write:
cd (Here you should paste the ubication of your extracted File Ex: C:\Users\Josh\Downloads\Root Ascend G7)
Now you are in this ubication that includes adb. Write:
adb devices
You should see: List of devices attached, a code and the word device (There is a capture below). If you do, we can proceed.
3.- Type :
adb reboot bootloader
It should load a white page with the Android pet and the words FASTBOOT&RESCUE MODE Below there is the phrase ''PHONE LOCKED'' in color. Now type:
fastboot oem unlock *********** (The code Huawei gave to you)
Now your phone will make a factory reset. You will see how it reboots by itself and back to the default settings. You will need to activate the debug USB mode again. By this point its supposed your bootloader is now unlocked, to probe it, we will type again:
adb devices (To check it is correctly plugged)
Then we will type:
adb reboot bootloader
And now at the end of the page it should say: ''PHONE UNLOCKED''. If you do, we can proceed.
4.- At this point, you have two options: You can replace your stock recovery mode by a ClockWorkMod Recovery (I strongly recomend you to do that) or you can just ROOT the phone whithout replacing your stock recovery.
If you decided by replacing your stock recovery follow the next directions: We still have our CMD window opened and running adb while the phone it is on the bootloader mode. So now what you have to do it's to type:
fastboot flash recovery recoveryP.img (CMD will work and show a few commands)
And after that type:
fastboot reboot
Your phone will reboot again normally and we can proceed.
If you decided not to replace your stock recovery instead of typing ''fastboot flash recovery recoveryP.img'' you have to type:
fastboot boot recoveryP.img (This will send you directly to CWM recovery)
5.- You must acces to CWM Recovery.
If you installed it on your phone, turn off your device and then press the power button and vol+ until the Huawei logo appears, you should be in the recovery mode by now.
If you didn't install it, you already are in CWM recovery.
6.- With the vol and power buttons or the touch buttons at the end you should be able to navigate on the recovery. We go to:
Advanced Functions->Re-root System (SuperSu)->Yes-Apply SuperSu (You will see a few code at the end of the screen)
7.- Without leaving the recovery mode, go to the main screen and now we go to:
Install Zip->Choose zip from /sdcard->superuser.zip (The one that you previously putted on your microSD)->Yes-Install superuser.zip
(You will see again a few code at the end of the page) We go back to the main screen and Select:
Reboot System now
8.- It's supposed we are ROOT now. At first you will see the ''superuser'' app installed. To probe that works, Install ''android-terminal-emulator-1-0-70-multi-android.apk'' that it is included on the folder ''Terminal'' form the file you downloaded. Now open a new terminal window and type
su (If everything worked, superuser will ask for permissions)
8.1.- Restore your data with the Huawei Backup App
And that is all we have superuser acces now. If you have any question or issue let me know and I will help you.

Hello everyone, I have a big problem with a Huawei G7. I did Philz Touch and Root. How can I go back to stock rom?
I've emailed Huawei 3 times now, left a week in between emails, and still haven't received my unlock code. Has anyone else had this issue?
Thanks

It looks like that guide has gone offline (and has been cloned on a few dozen shameless websites), so I thought I'd rewrite it for the sake of anyone else needing help. All of the files can be found around this site, and I'll do my best to update this later with links. But for now, I'll post the instructions. Additional thanks goes to @xBIGREDDx and @anggusss.

- Boot.img: https://mega.co.nz/#!Fk4FUSza!1gY1RjvnEI_HS0zk17WTHiywXFWc1VOCH-P2V5fVFPI
1. Phone Flash Tool
- Install USB drivers (if on Windows)
- Install Phone Flash Tool Lite
- Run PFT, open "Dell_Venue_8_7840_Lollipop_5.0.2_qs_rd_opensource-blankphone-userdebug-1397.zip"
- Select "flash-DD0_BB.xml" and flash it
- Tablet will restart in bootloader, flashing isn't done yet, so wait
- Sometimes it can be hard to get the progress bar past 4% before things fail. Just keep trying if this happens, it'll randomly work.
2. Tethered Recovery ("IntelAndroid-FBRL-07-24-2015.7z")
- Unpack the system image (from "system.zip") to a convenient directory
- With tablet still in Bootloader mode, open app, select CWM mode, then T4
- Phone will restart in CWM once everything loads
3. Flash system
- Go to the mounts / format area, format "/system" and then unmount it
- Insert Micro SD card and mount it
- Format "/external_sd"
- On computer, type "adb push <path-to-system.img> /external_sd/", wait for it to finish
- When finished, type "adb shell" to enter the device shell (make sure the prompt is "~ #" to make sure you are root (or type "whoami" at the prompt to confirm root)
- (If not root, restart to bootloader and trigger the tethered recovery again. You should be root this time.)
- Type in "dd if=/external_sd/system.img of=/dev/block/by-name/system" and wait for it to finish
- When finished, type "exit" on your computer to close the shell
- Reboot the device (to bootloader)
4. Flash boot
- Back on the computer, type in "fastboot devices" to confirm the tablet is connected
- Type "fastboot flash boot <path-to-boot.img" in order to flash the boot
5. Reboot
- On the device, tell it to boot normally
- Wait. It's a first-boot so it's gonna be a bit slow as the cache is built and whatnot
6. Enjoy!
7. (Optional) Root using the Update-SU.zip using the tethered mode again.
I noticed that it won't take any updates so this leaves you vulnerable to the Stagefright bug. It also sometimes boots to the bootloader and waits to you to select normal boot. Sorry. (Anyone know how to help?)

Any news? I'm stuck at 5.0.2. I wonder if it's possible to port cyanogenmod.
Hey there! Super helpful tutorial and most helpful so far that I found! However, my tablet just goes black after I press Normal Boot and just stays that way. Also when performing ADB Shell (Mac) for some reason it stays in the shell for few seconds and goes back. Any ideas why that might be happening? On top of that I can only enter the shell command really quickly so I have no idea when it finishes copying system.img across... Any help would be appreciated!
Hi guys,
does this method flash the 7840 with a 5.0.2 image or with a 5.1 one?
Thanks
I tried and I can reply to myself: it restores a clean 5.0.2 image ...
EDIT: xposed framework work perfectly on 5.0.2 . I'm perfectly happy with it now
Guys, please disable Driver Signature before installing ANYTHING on your PC to mod, change or rescue your DELL 7840
Intels Platform Flash Tool wont flash ( ifwi error ), and tethered recovery wont upload through bootloader
took me a while to realise itself, even though i did it many many times, after not doing for couple of years, i almost forgott that you need to allow unsigned driver installatino before
have grait ****,
Iko
What if you can't boot into fastboot mode? When I try to boot into fastboot, the screen only shows a battery logo with a question mark inside. I saw that there's a fix for this problem on Intel processor devices like the Zenfone and Del Venue 8 3840 using xFSTK Downloader. But that requires dnx_PRQ.bin and droidboot.img.POS.bin, which I don't Dell ever released. Any solved this problem before?
Flash tool wont detect tablet
So i would love to try this out, im new to this whole thing and have the problem that the flashtool cant find my device
Any Tips ?
I'm unable to get further then 3%, at best. my tablet starts and shows USB icon, nothing more.
anybody has solved this ever ? has unbricked this model ? I have searched everywhere, not found any one person who solved this with usb ICON showing.
please help, if you know how to .
Intel Flashing
You need to use 'On Demand Flash" option from Intel Flash Tool. Start flashing from computer and continue on your device.
For Venue 7840
- Unplug
- Power off
- Press and hold both Volume keys
- Plug USB cable
- Release keys
It will start loading automatically
I've use Intel Flash Tool Lite 5.3.2
wirebook said:
1. Phone Flash Tool
- Install USB drivers (if on Windows)
- Install Phone Flash Tool Lite
- Run PFT, open "Dell_Venue_8_7840_Lollipop_5.0.2_qs_rd_opensource-blankphone-userdebug-1397.zip"
- Select "flash-DD0_BB.xml" and flash it
- Tablet will restart in bootloader, flashing isn't done yet, so wait
- Sometimes it can be hard to get the progress bar past 4% before things fail. Just keep trying if this happens, it'll randomly work.

Use fastboot to flash the stock ROM instead of Intel flash tool. (If you know what you're doing, just read the part in blue below.)
fastboot is for Android devices, whether they have Qualcomm or Intel processors. Using Intel Flash tool is more akin to using Qualcomm's QPST for flashing, which is also something that should only be attempted
after trying fastboot. The Intel flash tool expects the .zip file to be in a format such as a Chuwi ROM with Windows is. Intel Flash tool unfortunately doesn't expect the .zip to be in the Android format like Acer's stock
ROM "AV0L0-something.zip" is.
With the tablet off, and plugged into your computer, hold both volume buttons and power it on. (You probably already knew this step, but here just in case )
It will vibrate longer than it usually does when turning on.
The screen should indicate that the device is in download, or "dnx" mode.
Open a command prompt in administrator mode,(the title of the window should say "Administrator: Windows Command Prompt" or "Administrator: <current directory>")
Type:
Code:
fastboot
If command not found, then either copy fastboot.exe into System32, or add the path it is in to your PATH variable, or simply navigate to its directory within the command prompt.
If you're not familiar with the PATH variable, you can just shift+right-click on fastboot.exe, click "Copy Path" and then paste it into the command prompt to use it's full path in place of simply "fastboot".
Once you're able to type "fastboot" or paste the full path and press enter and it returns the fastboot help message, type:
Code:
fastboot devices
this will either return a single line containing your device's serial number, or it will return nothing at all
If you see a serial number, you're in business.
(make sure the tablet is not low on battery before you continue):
Type:
fastboot update <path to ROM .zip>
Click to expand...
Click to collapse
This should initiate a full reflashing of the stock ROM. The tablet will reboot a couple times, you should hear/feel an even longer vibration during the process, do not touch it or unplug it from the computer until it is at the initial Google device setup screen waiting for your input.
Note that this full reflashing will also overwrite TWRP with the stock recovery.
if "fastboot devices" returns nothing at all, and also doesn't say "command not found" then do the following:
open device manager on computer, find the tablet's driver (may be under portable devices, or COM ports. sometimes under USB.)
if you can't find it, look for an "unknown device" with a yellow exclamation mark on it. If you see that, then you may not have had the driver installed in the first place. To verify, unplug the tablet from the computer
and see if the unknown device disappears from device manager.
If you were able to find the tablet in device manager, then right click and "Uninstall Device" and be sure to check the box to uninstall the driver software as well before clicking OK.
Then, unplug the tablet from your computer if you haven't already.
Download the latest driver from the same place on Acer's website that you downloaded the stock ROM from. Install the driver and restart your computer if it says it needs to.
Afterward, ensure the tablet is off and try the steps above again.

my sister is very grateful
Thank you very much.
What build date has this rom? Sec. patches?
Can you please post your local manifest?
Very interesting guide, unfortunately the links don't work...
Is it possible to restore them?
Tanks. Max
I think its first guide how to do it because every other guides were for TB2-X30F but not for TB2-X30L.
I have only found lineage os for x30l, can someone please link lineage (Android 7) for x30f?
The difference between L and F is that L is the sim card variant. Ive read several people getting "insert sim card" when installing L on a F tablet. So I dont want messages like this.
Thanks for this tutorial. It was possible, to upgrade this old Tablet.
Do you know, if there is anything newer version for our Lenovo?

The tablet can also run on LineageOS 16 which is Android 9.
As I saw that the guys in the Russian 4PDA-Forum had been able to create a LiOS16, I was able to make some adjustments and compile a ROM with most recent security patches which now runs on my good old TB2-X30L / TAB2 A10-30:

it seems that google drives are off. Can someone re-upload please?
Hallo,
I have installed LiOS14-UNOFFICIAL-TB2-X30L.zip. The installation was without problems.
But I am having problem with WiFi - problem of MAC 02:00:00:00:00:00. I have tried a lots of tips but nothig worked. Two times I was succesfull to set some MAC, but always, after while, it was gone. No able to reproduce to set.
Is it really so difficult to set somehow the MAC addres for the WiFi?
As I understand the setting of the MAC differs between different releases of OS. Does anybody know how it work in this release? It should by known where this relaese expects the MAC setting. Am I right?
1. temporary succes: Setting MAC in system/etc/firmware/wlan/qca_cld/wlan_mac.bin (I think. Its longer time ago and there was more attempts). It lasted for few months. It is not mine device so I don't know how it was handled.
2. temporary succes: I copied system/etc/firmware/wlan dir to system/vendor/firmware/wlan. I did it based on how it is in Samsung Galaxy S4 mini with Lineage 16. It worked. After restart I had to swith off and on the airplane mode to set MAC. After few attempts it was gone. No able to reproduce to set the MAC.
I am not Linux expert

Thank you very much, install your rom on my TB2-X30F and it goes very well, the only drawback that I present is that the wifi is very slow but the rom is excellent, thank you very much for your work.
