If you already tried to backup the rom from your Huawei u8350 Boulder with CWM you must have realised it doesn't work. The culprilt? Huawei made 2 changes from the normal Android partition pattern: we got a /cust partition, thought so that phone provider can install their bloatwares, and for unknown reasons we got 2 userdata partitions.
But there is a solution, thanks to Gulyuk's great work.
Prerequisite:
A Huawei u8350 Boulder / Orange Barcelona (obviously),
A working ClockWorkMod Recovery for U8350,
The two attached scripts
How to use (again, i'll take Gulyuk's explanations):
Backup boot, system, cust via CWM recovery
Download Attached File backup_by_Gulyuk.zip (445.33K)
Number of downloads: 0 and put it on the microSD card (do not unzip).
Ensure that you have enough (about 261 MB) free space on the microSD card.
Enter ClockworkMod Recovery.
Select "install zip from sdcard" in the menu, then select the backup_by_Gulyuk.zip file. Wait for several minutes while the backup script works.
Select "reboot system now" to exit from recovery.
The backup script should create the firmware directory on the microSD card (seen as /sdcard/firmware from the phone) with these files:
boot.img — dump of the boot partition (kernel and initramfs);
recovery.img — dump of the recovery partition (the one you installed);
system.img — dump of the system partition in yaffs2 format;
cust.img — dump of the cust partition in yaffs2 format.
data.img — dump of the userdata partition in yaffs2 format.
data2.img — dump of the userdata partition in yaffs2 format.
Running the backup script when the /sdcard/firmware directory already exists overwrites the previous contents of this directory (including any extra files which were placed there). Currently there is no way to keep more than one firmware backup by this method, unless you rename the firmware directory manually (but then the backup cannot be restored until you rename or copy the directory back).
Restore boot, system, cust via CWM recovery
Download Attached File restore_by_Gulyuk.zip (260.83K)
Number of downloads: 0 and put it on the microSD card (do not unzip).
Ensure that you have the firmware directory on your microSD card with valid firmware image files (boot.img, recovery.img, system.img, cust.img, data.img, data2.img).
Enter ClockworkMod Recovery.
Select "install zip from sdcard" in the menu, then select the restore_by_Gulyuk.zip file. Wait for several minutes while the restore script works.
Select "reboot system now" to exit from recovery.
Warning! Warning! Warning!
I tested both scripts on by own u8350 and it's still working, but I give absolutely no warranty about these scripts and how they works. If your phone burns, bricks, looses faith in you or try to run away in love with the neighbourg's dog IT IS YOUR RESPONSIBILITY.
If you want to share your wonderfull customised ROM with these scripts delete data.img and data2.img before sharing as they contains your personnal datas (google accounts, emails, and so on...).
before to try someone else's ROM, backup yours, then copy the "firmware" drawer from the SDCard in a safe place (dedicated to a french fellow that lost its keyboard configuration ).
"install zip from sdcard" option not given
Hello. Noob here. I'm following the instructions for the section "Backup boot, system, cust via CWM recovery", but the "install zip from sdcard" option is not appearing so I need some guidance, please.
General info: Orange Barcelona, UK, unlocked, rooted and verified, no sim inserted. CWM is installed.SuperUser is installed. Debugging and Unknown Sources are enabled, Fastboot disabled. The sd card is mounted and has plenty of spare capacity. Recovery Manger, Restore.zip and backup_Gulyuk.zip are on the card.
Can someone please point out what the noob is doing wrong?
Thanks,
Kate
EDIT: I started again from scratch and now the phone just reboots from CWM so I now no longer get a menu at all.
For those who want to Unroot their Karbonn A9 with less chances of without bricking
Before performing any operation make a Nandroid backup using CWM.
Download this http://karbonnklinic.com/download/Downloads/sw/A9.rar 145 MB Update file which is in zip then extract it on your computer. After extracting there will be another zip file named Update.zip.
Now put the Update.zip on your phone's sd card, please make sure you have not put it under any folder.
Now reboot your phone into recovery and then install choose the option Install zip from sd card and then choose the option Install Update.zip from sd card, when you will select it, it will find the Update.zip file automatically on your sd card and ask you to install. Just install this file, it will took 2-3 min for install.
After successful installation don't reboot the device, just go to recovery andd wipe cache partition and then under advanced select option wipe dalvik cache, if you don't perform these option then you will stuck on the Karbonn Smart start-up screen.
Hit thanks Button if you like it.

Format ext-sd using recovery once.
I faced this issue when I partition and used link2sd right after that, but when I formatted ext sd from recovery, it worked fine.
Remove links of all apps, flash this in recovery, reboot, use link2sd.

2.do i press the download button keeping the usb plugged in/not
3.how much space is alloted by this process should it cover 20apps with 50mb each at the same time
4.if in the future i decide to root it with cwm recovery do i get the same alloted space by this process or not
5.what is your opinion of this apps like link2sd,foldermount,internal to external sd can these be used for low internal storage and would these apps work on the device???

Micromax Unite2 A106 8GB vs 4GB models
I am very new to mobile dev. stuff. I recently bought Micromax Unite2 A106 8GB model.
I have been searching internet for some information and there is none which clear enough for me to understand.
I have a few questions, if you can answer, i'll be glad.
1. Is the ROOTING process and software and files required for rooting Micromax Unite2 A106 8GB same as Micromax Unite2 A106 4GB?
2. Is REPARTITIONING process and software and files required for Micromax Unite2 A106 8GB same as Micromax Unite2 A106 4GB?
Here are EBR1 and EBR2 for 8GB model.
here are the EBR files for Unite 2 8GB model.

I have flashed a new rom on my phone with twrp 3.4.0.0
When I got to the new UI I had no free space (both internal and sdcard)
Back to twrp I took these steps:
1. Boot into TWRP recovery.
2. Select Wipe » Advanced Wipe.
3. Tick/check the Data partition.
4. Select Repair or Change File System button.
5. And lastly select Resize File System button.
that solved the internal storage size, but the storage of sdcard shows 80MB when it should read 128GB.
I tryed the same method for sdcard but it cant be done on sdcard selection.
Is there any solution without formating sdcard?
if not please provide a solution with formating on twrp.
I have searched for a solution but no result...
Please help! i have no time to search right now!

Problem solved by replacing twrp with pitchblack ver.3 and repeating the procedure mentioned.
I flashed a stock rom (replaced the stock recovery with twrp though), it was stuck at the Alcatel screen, so I went into twrp. I tried reparing, resizing, changing file system of data, system, and cache (which all showed 0 mb), then cache and system got fixed and it said ext4. However, data still shows 0 mb and despite trying all kinds of fixes (like wiping, doing a factory reset, changing file system to ext2, ext3, ext4, fat etc. which all fail) I found online it's still the same. When I tried flashing userdata using SP Flash Tool, it said "not enough space". I found two scatter files (attached to this post) but they seem to differ.
What should I do?
Hint: Add TWRP to this thread's title because it's a TRWP related issue.

How is it TWRP related? SP Flash Tool says it can't flash user data because there is no space because /data is seen as a 0mb partition.

My guess is /data got encrypted by TWRP, hence it actually can't get mounted. But I may err ...

That makes sense, I'll try adding the tag. Do you have any idea how I can check that or decrypt the partition? It looks like not only data but many other partitions aren't visible as well like /system.
...
It looks like I can't edit tags afterwards.
Looks like there's a problem with userdata
You have to format it, and then reflash the stock rom
Open sp flash tool
Load your scatter file
Go to the format section at the top of spflash tool
Select manual format flash
Select emmc user.
As the begin address of userdata is
0xABD80000
Input it in begin address box
As the size of userdata is
0x124D80000
Input this is the format length box
Click start
Flash the stock rom and reboot
I got these values form your scatter file

Thank you! Which scatter did you use? I uploaded two different ones for the same device but I used the one named "mt8127_android_scatter.txt" to flash the stock rom.
