If you can't find a software fix for your problem , no guarantee or anything also I'm not the greatest at this but I had a power button malfunction on my Acer iconia tab, dropped it from 4 ft and power button housing inside tablet snapped off the mono, I just took apart and placed back in place didn't have solder So I used a piece of rubber and wedged between the tablets case and the housing on top of the power button mechanism and put back together worked great , I had dropped my cat b15 in my turtles tank to show off, only it isn't sealed anymore like before I threw on the ground so not as waterproof as I expected got condensation build up behind my screen and the camera lenses.... so I had to take it apart to soak up all the water , this phone was way easier to disassemble than my tablet was main lay because this phone has screws to help ,tablet had a sealed frame I had to break into , but idk how iffy you are with taking stuff apart, I do t do it for a living I'm just a MacGyver For that type of stuff BC I had it apart in no time and worked better than before I had taken it apart

1. Take back off phone

*unscrew screws behind and around battery

2. Unscrew the 3 screws on each side of the phone holding the metal sides on

3. After that it should be ready to take apart and from there you'll just have to take a look at why the power button is stuck or not working

Please be careful did this a while ago so can't remember anymore steps after disassembly if I had the right hex bit I'd do it again But I had to use a flat head bit and am afraid if I do it again I'll strip the heads on the screws other wise I could do it again and take pics for ya sorry hope you get it working right

??????????????????????????????
[Android General] oldskool dave:
I'll try and help ya out

I messed mine up a while back and had fixed it back to normal I'm going to try and upload the 3 files I changed so you can download them maybe and overwrite your old ones....here it goes....

Extract files to your device somewhere you can locate them at

Copy and paste them to system/etc/and overwrite existing files reboot after that should work after that

If this helped please thank me
[Android General] oldskool dave:
yes easy

Use titanium backup to remove system apps or any root uninstaller must give app root permissions to do so but may not update later if any is available if it checks for system apps

Hello once again

I was finally able to get the memory swap done only have a 4 GB SD but it worked

only thing I'm confused on fixing is the fact that before this it showed 1.45 GB internal storage and 1.06 phone storage now shows 4 GB phone I believe and 1.45 internal so where did the other 1.06 GB go to and how do I integrate it into the 1.45 GB of internal that's now showing to make 2.51 GB for total internal because I know its there.

Do I need to create a new line to specify partition?

So, has anyone else notice that B15 is not capable to connect to 802.11n wifi? I can see it in the list, my nexus 7 connects perfecly, laptop too, but CAT waits for couple of minutes and then writes "Authentication failure". And connects instantly as soon as I change router settings to NG-Mixed.

I never look at the router mode so I'm not sure sorry can't help

Will rooting the phone allow hosting of USB devices (e.g. attaching USB memory stick)? Or is this not supported by the hardware?

No sorry haven't had time to really mess around with it, just finished moving etc... Now I'm settled in and will see what I can do , noticed today that I must have deleted a ROM file that enables the choice of picking a video wallpaper and that has brought me back here to ask help on that topic but I'll get the splash tool installed and hope I can understand it all right away ... On another note I'm about to just got buy the damn phone again straight cash and backup that ROM then return the thing next day that'd help out lots

---------- Post added at 11:44 PM ---------- Previous post was at 11:24 PM ----------

It was rooted more than likely but did you have a superuser app to grant root permissions to other apps? I had to do that with mine after rooting with framaroot

There is now a configurator in play store for both types of cat b15 ss and ds and it automatically sets the correct network config.

Has anyone managed to root CAT B15Q ?
[Android General] VonVarnick:
need help with bricked CAT B15

hi

I successfully rooted my phone, using kingo root. I used this app because other methods did not work.

I started to experiment with the new capabilities of a rooted phone, but I overextended a little....

I tried to metamorph the lock screen buttons.... when the phone restarted, it froze on the boot screen (CAT letters with white background)....

I can access the android system recovery, by holding the power button and volume up key. I tried to flash it, but I might have done it wrong because it does not work... I tried to do a factory reset, but it doesn't work either....

does anyone have any idea what could be done to unbrick the phone?

Any help will be greatly:good: appreciated
[Android General] VonVarnick:
Could solve problem

I was able to flash back the os, with a backup file in this thread. But it is for double SIM, anyway its much better than a Brick :laugh:

The problem I had, was that I did not install correctly the driver for the computer.

If you know were I can find, boot and recovery files for CAT B15 single SIM, please tell me

keeping root after OTA upgrades can be achieved easily.

There's an iso image in /system/mobile_toolkit which only contains some usb pdf:

shell@android:/system/mobile_toolkit $ ls -al

-rw-r--r-- root root 651264 2014-10-12 02:37 iAmCdRom.iso

which is mounted on /mnt/cd-rom without the nosuid mount flag:

/dev/block/loop0 /mnt/cd-rom iso9660 ro,relatime 0 0

You just need to replace this iso with a custom made iso containing 4755 su binary and reboot.

shell@android:/data $ ls -l /mnt/cd-rom/su

-rwsr-xr-x root root 125420 2014-10-12 02:17 su

Sample iso at speedy dot sh/VSeTW/su.iso.zip

As the OTA doesn't replace the iso image, you'll keep root.

shell@android:/data $ /mnt/cd-rom/su -

root@android:/data #

B15Q_GENE_DS_1.010.000 move apps to SD

Hi all,

I have B15Q_GENE_DS_1.010.000 and in this post there is vold fstab mentioned in etc system.

On my device there is only a fstab, fstab.nanad and a fstab.fat.nand located on "/".

While fstab can be edited or copied the other mentioned files cannot.

I am also unable to root the phone with mtk droid so that I can flash it with the firmware mentioned but i did root it with king root.

Even so in mtk droid the device appears not rooted and when i tick root it it states "Press Restore button in right bottom corner on phone screen! " wich I did on the device and after 4 seconds on the device says restore ended while the mtk tool keeps processing it forever.

I installed CWM so that I do have a proper backup.

Can you please upload a rom zip file with the sd device as a primary mount for CWm so that i can flash my dual sim B15q.

Thanks!

PS: root checker confirmed that the device is rooted
[Android General] hyperblue:
Move applications to SD possible on Cat B15Q and all other phones with root access

Hello,

I managed to fix my own issue :D

First of all we need to have an external card with 2 partitions and Root access!

Partition1 FAT32 Primary

Partition2 EXT4 Primary

(to do it I used: MiniTool Partition Wizard )

Install Link2sd latest version from playstore (it's free)

Then you will need to patch it using Lucky patcher :)

if you get "Package Invalid", please follow step below (thanks to jasi2169)

How to Make Link2SD v3.5 or v3.5.1 Plus

Install Lucky Patcher v4.3.6

Go To SDCARD/LuckyPatcher/jasi2169_com.buak.link2SD.txt

Open It

You Will See The First Pattern

{"original": "?? ?? ?? ?? ?? 00 00 03 55 10 67 0F 00 00"}

Now, change 67 with 71 like this:

{"original": "?????????? 00 00 03 55 10 71 0F 00 00"}

And Save The Text File

Now Use Lucky Patcher to "Custom Patch" Link2SD v3.5 or v3.5.1.

Or you can download this txt file, extraxt and put in (replace the old one) *sdcard/LuckyPatcher/*

Download Custom Patch File:

tusfiles.net/eeq1e8apwxq1

After patching open link2sd and choose partition type (ext4)

If it doesn't work at first, try and try again.

Then reboot the phone.

Open again link2sd, choose de desired app to be moved and check create link.

Then mark all the checkboxes and press ok.

The apps should now be moved (linked including the data).

PS: do not remove the SD or change the connection type to mass storage as you will have issues launching the apps and relinking them.

This solution works on all phones! ;)

KitKat for B15? Rooted/nonrooted images

Hello,

I am new to Android hacking. But after fighting with "not enough free space" message (and having 32Gb external SD card which is almost free) I realized I need to do something with my CAT B15.

I have several questions from the newbie.

1) I realized CAT prduces now B15Q which has more recent Android version that B15. Is it possible to take that firmware and install in on B15?

2) Root. I have found some "simple" method (framearoot) which does not work (according to checkroot app) and some complicated methods with SPFlasher. Is there any soultions which can be used by Linux or Mac user (I do not have access to Windows)?

3) I have found several images. Some of them are "Rooted", some of them are "Unrooted". If I need root access (to repartition the phone and move as much as possible to the SD card), which images are needed? Rooted or Unrooted? I guess, rooted?

Thank you in advance!

Need help on Cat B15 stuff

Hi people, i see this is the most rich/active thread on this phone that i just got from a friend. It is a EMEA_SS_1.041.00 Cat B15. This is the things i would like to accomplish

1) Swap both internal storage and internal sd card in one single storage for better handling of apps

2) Enable the Dual Sim support? My phone has the second sim slot but it is not detected and i don't know if this can be enabled by a firmware tweak or requires a different hardware in which case nevermind.

3) Root the device (I already rooted the device using Farmaroot and root checker says it is rooted OK)

4) Possibly install a light custom ROM, maybe Cyanogenmod, i don't know, otherwise stock android with normal root is good enough.

I have Linux so i wonder if this is possible doing in this platform. It's kind of annoying that all android stuff can only be done easily in Windows, since Android is quite more close to linux in it's nature.

Can i do all those things? If so, can be done in Linux? I'm sorry to ask this but all the posts are quite confusing since the time goes by and new user contributions tend to be somehow confusing.

Please i would appreciate any help.

Cheers!
