[Complete] Huawei U8510 Ideos X3 (Vodafone) Australian stock ROM

Hello All,
I have Huawei u8510 x3 (Vodafone branded) Australian (Model: HUAWEI U8510-7).
I rooted my phone, took ClockWorkMod backup and flashed generic stock ROMs (Phones 4 U - UK Generic Stock ROM).
When I revert to my saved backup, I notice that my boot animation has changed. After lot of reading I have realized that ClockWorkMod (did not backup /cust and /userdata2 partition that contained the Vodafone stock branding).
Can anyone please update a Australian Stock ROM (U8510-7 Australian Stock ROM) for this device? If not, can you please link to a backup of the /cust and /userdata2 partition and instructions on restoring this?
Thanks so much in advance.

I have the same phone, still in stock condition. Could back up these folders and upload the data somewhere for you, if you like.
Incidentally, I have been trying to root this phone with no success. How did you do it?

Steps to backup stock /cust and /userdata2 partition prior to flashing new ROMs.

Thanks mate. What OS are you using? I used Windows 7 as Windows XP did not work for me.
Even with Windows 7, I had to manually install the driver (device manager, update driver, path to driver files downloaded).
Follow the guide here: http://forum.xda-developers.com/showpost.php?p=19246491&postcount=1
to root your phone. Meanwhile I'll find out instructions for fool proof stock recovery partition backup. For now I have out they only way to backup /cust and /userdata2 partition here:
http://66.163.168.225/babelfish/tra...lash-partitionen-von-supertoast-anpassen.html
Here is another way to completely take a backup of your stock ROM prior to flashing new ROMS:
http://androidarea51.com/q-kernel-a...?PHPSESSID=nk8an4uv09a23ta6q0t05nk3j0#msg2503 --> Follow steps in Reply#2
OK, I have thought about this and reread the backup partitions from the 1st Link in this post. Essentially the steps to take a backup of the /cust and /userdata2 partitions are:
1. Root your phone (If you follow guide: http://forum.xda-developers.com/showpost.php?p=19246491&postcount=1, ClockWorkMod recovery would have been installed.)
2. Download backup_partitions.zip from here http://66.163.168.225/babelfish/tra...change_partition_layout/backup_partitions.zip and save it somewhere in your sdcard (/sdcard is recommended)
3. Reboot into recovery mode (reboot phone, press Vol+ and Power ON button at the same time when restarting)
4. In CWM Recovery mode, Install zip from sdcard and choose backup_partitions.zip (downloaded in step 2)
5. Reboot phone.
6. Check the root of your sdcard. You should see the following files:
cust_backup.tar --> Backup of your /cust partition (with Voda boot logo and branding)
userdata2_backup.tar --> Backup of your /userdata2 partition (more oem stuff I think)
If you have reached thus far, I would really appreciate if you could please zip the above 2 .tar files and load it in Dropbox/rapidshare etc.
Am certain that the above 2 files will NOT have any confidential data. All of your confidential data (account information, sdcard backup etc are in data.img)
Am happy to help anyway I can when you get stuck rooting or taking the backup.
UPDATE: Found another method of backup data in /cust partition.
I quote a post by knzo from: http://pzieye.centelia.net/blaze/viewtopic.php?id=7 (requires registration)

Here's a tutorial on how to remove the crap from your operator such as vodafone. You need root for this.
0. Backup first (optional but highly recommended)
- Download busybox installer from market, run it and install busybox (1.19 on /xbin for example)
- Download terminal application from market, run it and do these commands (without the ""):
- "su" (click allow when it asks you for root privileges)
- "mkdir /sdcard/custbackup" (you'll need a microSD card for this)
- "cp -r /cust/* /sdcard/custbackup"
- Done, backed up contents will be in your microSD card on the custbackup folder
1. Removal
- Run these commands on terminal application:
- "su"
- "ls /cust/" (take note of your brand; in this case, let's assume it's vodafone)
- "mount -o remount,rw -t yaffs2 /dev/block/mtdblock8 /cust"
- "rm -r /cust/vodafone/"
- "reboot"
- Enjoy your unbranded device
2. Restore (optional, needs step 0 to been made)
- Run these commands on terminal application:
- "su"
- "mount -o remount,rw -t yaffs2 /dev/block/mtdblock8 /cust"
- "cp -r /sdcard/custbackup/* /cust"
- Done

TWRP can flash .img files without having to do anything special.

I dont think you've booted into TWRP yet, I think you're looking at bootloader, select recovery and see if it boots to TWRP.
TWRP has more than just 2 options, are you sure you have TWRP? What version is it? Does it look like this?
http://cloud.tapatalk.com/s/58a730280544c/Screenshot_2017-02-17-12-15-48.png?
If that's what you have, select Install then find your .img and flash it.

I remember now that TWRP doesn't flash system.img correctly, system.img isn't a standard .img, you need PC and use fastboot.

I know it is too late, but you can enter in Advaced > Terminal and then run this command:
dd if=/sdcard/system.img of=/dev/block/bootdevice/by-name/system
If your mobile phone doesnt have by-name symlinks you will need to enter the correct partition.

hi aex, I have the same problem but I dont have the folder
/bootdevice/by-name............
can you help me?

it will not work.
try to make a folder and "mount -o loop file in it.
and it will be not mounted also if you specify file system type.
(if it work probably you can use the file)
so ,i don't know how fastboot write in partition or probably
in to file system.
however if you do a dd of your current system partition in a file , after will be correctly mounted , or rewrited correctly in the original partition if you need.
then probably you cannot use fastboot system.img directly in twrp shell (using dd)
this is my experience (e2303 sony / pexorom 3.0 twrp 3.1.1)
if you are searching a fast way to know system partition device block
cat /etc/fstab
and look for system
or just mount system in twrp , then in a terminal do a
df -h
and search for system
for e2303 was /dev/block/mmcblk0p30
(example)
twrp have busybox and light kernel.
so , is linux.
for better support try to ask
tonystark88

u need to use simg2img
(sparse file format compression)
system partition device name can be different on other phones.
done.
img can be write by twrp whitout pc/fastboot.
c'ya
giuseppe

just go to file manager and search for system partition, and on first part type your system.img location and 2 part type just system location

I did this Steps on my Huawei P8. Sim2Img reported a non sparse image, so i moved directly to the DD steps. But after writing the image to the partition, the /system Partition cannot get mountet...
What the hell iam doing wrong ????
I extracted the system.img from an update.app Firmware file.
Its the same Firmware file i flashed before with the dload method.
I want to install TWRP on my Phone with an faulty USB Port. So i have no PC / ADB. I Installed the Firmware via the official Dload Method from Huawai. Then i used this crappy Kingroot to get root and installed TWRP. Now i wanted to flash the stock system partition to get rid of Kingroot for Safetynet.
But why i cant just flash the systempartition ?
Or is there another way to gain root for 15 seconds without traces ?

Why not just use the settings in Kingroot to remove root? Or convert from Kingroot to SuperSu then use SuperSu app settings to remove root?
You don't have to flash the stock system to remove root.

Kingroots uninstall leaves traces in /system/xbin and Safetynet wont work. Why i did not try Supersu ? :-/
But i managed to flash the system.img without problems.
First i tryed an extracted system.img from the Huawei Firmware extractor and Sim2img reported an invalid sparse image. So i thought it must be a raw image.....And this was my mistake. It is a useless image for TWRP.
So i created a flashable zip (TWRP cant flash this, too and the /system partition is not mountable after flashing / installing this zip.
BUT, the system.img INSIDE this zip is a spase image, which sim2img can handle. It gave me a nice raw image which i just dd´d to /system and BINGO, my phone starts up normally
The Short Version :
- Create a FLASHABLE ZIP with the Huawei Firmware Extractor
- use SIM2IMG in TWRP Terminal to get a RAW Image.
- dd´it to the /system partition

System img
You use the restore in twrp to flash your system img, you just until the other boxes

Edit: Sorry wrong thread

Lenovo K5 Pro ROM img
After flashing img file (using TWRP 3.3.1) the phone (Lenovo k5 pro) starts in bootloader mode. Everyone can help?

Help u
Hi u can download a deodexed rom because ais doesn't support some stock roms for ex ch Samsung roms. then decompile it.then decompile it with rar or zarchiver or etc. Then install android image studio (ais) from google
Then open it and tap unpack/mount and select system.img or system.img.ext4 file in decompiled rom . After mounting, copy all files to a directory for ex emulated/0/system/system or another. Attention if you copy it in another directory, rename it as (system) now copy the boot.img from decompiled rom into emulated/0/system .then download this file
https://forum.xda-developers.com/an...oid-o-beta-redesigned-emoji-set-t3608280/amp/
Extract meta-inf file into emulated/0/system using winrar or zarchiver or etc. Now you need to have a system folder,boot.img file and a Meta-inf in diractory emulated/0/system. Now compress system,boot.img and meta-inf into one archive and after completing, turn of your device and boot it into twrp recovery and wipe data and cache without wipping internal storage then select install. Then tap select storage and select internal storage.then go to the file and select it and turn off zip singuature verification and install it after installing tis rom, install root zip file and wipe cache/dalvik art and then reboot your device. It may take between 5-25 minutes to boot. Enjoy your new rom
#issues
Sometimes your device maybe take bootloop so you need to install your stock boot.img file and after installing your root zip file choose wipe cache/dalvik art and then reboot your system.
#Alert
1.Don't install the recovery.img file which exists in the decompiled rom because it takes your device into recovery mod and not boot anymore and after you need to install the stock rom using PC
2.your device maybe take bootloop in this method so do it with your own risk

I've found a solution. So, I download standard miui firmware, 10.3.x in my case (Pie version), and then extract the content. In one of folders, you'll find vendor.img, copy this file to your /sdcard phone. Go to the TWRP terminal and execute this command: dd if=/sdcard/vendor.img of=/dev/block/mmcblk0pYY
YY is the vendor partition number, you can find it using mount command and carefully see which one is. Reboot and all is well. If your TWRP has an option to flash the vendor partition, it would be easier. Mine has no such option.
Read somewhere involving modifying xml file and using miflash, also emergency download mode (since vendor partition is readonly in fastboot), but I've failed to flash and the dd method above is succeeded. YMMV and good luck.
**update: it's persist not vendor, so change accordingly (vendor.img -> persist.img, also the mmcblk)

thanks

Reboot your device into TWRP again.
Navigate to Wipe > Advance Wipe > Data, and choose Repair or Change File System.
Press Repair File System to see if this fixes the issue. If not, continue.
Press Change File System, choose Ext2, and swipe to confirm.
Now switch back to Ext4 and swipe to confirm.
Go back to TWRP main menu, then the Mount menu, and check if your partitions can be mounted now
it worked it Mounted /system and i did what i need but when i rebooted it was stuck in bootloop, so i tried to to reflash boot.img/recovery.img to restart but nothing was working happening. so in a dumb moment i chose format+download option in SP Flash tools, and click it and i think it may may of deleted the preloader.bin :
so either its a Corrupted/Missing Preloader or when i did the stuff in twrp it screwed something like the Directories???
i have tried to find the rom/firmware but since it a china device its hard to find any info
so i would love someone that has this just laying around or what not, to if they could do a full backup i would love to unbrick it.

cant access system partition in twrp

hey i want to install a custom rom (gsi) so i hope some people can help me out
main info: i have a ulefone note 9p with mediatek 6762 (runs with mediatek 6765 android scatter) and android 10.
this twrp is a twrp 3.4.0. built for ulefone note 9p i downloaded from here:
unofficial twrp 3.4.0 Root Ulefone Note 9P - unofficial twrp
download unofficial twrp 3.3.1 root Ulefone Note 9P, user who own Ulefone Note 9P can root it by following the below instructions
unofficialtwrp.com
after going to the painful procedure of unlocking bootloader flashing stock and twrp modified rom + rooting the device
i stuck at the procedure to install a gsi image via twrp.
i already know that the device must be unrooted and i have already gained some experiences in flashing the rom
even after a few softbricks, so i will try installing this image with a stock rom and twrp after i received the help i need.
i use a sd card because twrp always disappears when i transfer a file via my phone and i land on stock recovery.
this problem solves when i root my phone via magisk. as i heard flashing gsi's dont work in a heavy modified state (like with magisk),
so a sd card solved this problem to run files on recovery mode without file transfer and rooting.
the problem i have is the following: i followed some instructions saying to wipe some data first in advanced wipe
- also the system partition which is not available. after that tried to install the image directly. as it finds the rom from my sd card i have to select the partition type to flash image
i only have boot recovery and super available but i need the system partition. i looked in the internet further (the painful process) and it gave me some hints going to mount.
there it finds the system partition but when i set a checkmark on it nothing changes, so this hint didn't helped me.
what should i do now? i'm stuck in some dead end and i don't know what to do it seems like this is the only way for me to get it work.
please help.

i think i found something. since my phone is rooted i also tried to delete system apps which also don't work. i tried many system app removers but it always give error. i think the problem lies in permissions that are not given to this phone. how can i get full access to \ system to gain full permission rights? i also have busybox installed btw

You've to mount the /system partition as RW in order to access this storage location.
Example code:
Code:
adb devices
adb shell "su -c 'mount -t auto -o rw,remount /system'"
