Kaiser SIM/CID Unlocking / HardSPL
A Soft Reset is a Power Cycle of the phone, basically, turning it off and back on again. A Hard Reset will clear all of the storage on the device. This means you will lose everything stored on the device (Not storage card), PIM data, photo's music, etc. Your phone will have the last ROM you flashed on it and nothing else. The bootloader is the SPL Questions? and can be used to fix problems or flash images to device ROM. Soft Reset
- Using a stylus, press the soft reset button at the bottom of the phone
Hard Reset Note: This cannot be performed while the device is connected/charging!
- Soft reset the Kaiser (above)
- QUICKLY press and hold the two soft buttons on the front
- Let go of the two soft keys once the message "This operation will delete all your personal data, to manufacturer default" appears on screen
- Finally, press the green call button to perform the hard reset, or press other key to cancel
Hard Reset in Pictures
- Hold Camera + Power buttons together and reset with stylus
- Using a stylus, press and hold the soft reset button at the bottom of the phone along with the camera button
- Release both buttons once the bootloader screen appears
Don't know what a ROM is?
- Watch this first, and read the [ROM Flashing FAQ|KaiserROM_FlashingFAQ].
Don't know what a SPL is?
- After reading the basics if you are still confused about SPLs, or which SPL you want, read [SPL Questions?].
Upgrading your ROM can void your warranty. Worried?
- Browse through how to revert back ROM and SPL for warranty return before you start.
Think you're ready?

For starters, check this one first.
For the latest Kernel, check the first post of this thread. DO NOT post questions/problems not related to Kernel
If you still having issues, take a look here:
WiFi not working? Receiving the message "Install modules for this kernel" ? Read this:
If nothing helped, perhaps your issue is release specific. If you tried several, and the issue shows up on every one, try posting in the above thread. If it's only specific to a given release, post on that release thread only. A advise though:
Post your type of installation (NAND or Haret ? All on NAND, or is DATA on the SD Card ? in a Partition or in a IMG file?) Do you overclock ? How? Atools or RogueTools inside Android ? How much ? Do you overclock the GPU ? What radio are you using ?
If you're not in the release thread, what release are you using? Be kind, and search the specific thread, there's a button for that. If the thread is not recent, there a high chance you're question as already been answered.
Quick generic how to install Android to NAND
Kernel -- *Kernel With Separate Cache Partition
Android ROM -- *Scoot CyanogenMod 7.1.0
Python -- *Python 2.7.2
1. Download and install Python.
2. Go into the Kernel thread, and download Cache Kernel & ATools.zip Inside this zip, you'll get the Kernel in a NBH file, atools.py to edit the kernel, and a androidupdate.tar. You must edit the kernel to suit your device and needs. So, run atools.py, press the open button on top, and open the KAISIMG-PANEL2-320-TILT0.NBH Inside it you should set the panel type, and the key map. It's virtually impossible to know your panel type, so choose one and test it. Choose also your keymap. I advise you to alter the cpu overclock, and slide the slider to something between 480 ~ 510 mHz. Also tick the GPU overclock. Done that, save, atools will alter the file name to KAISIMG.NBH. Save it in the root of your SD card. Kernel done.
3. On the root of your SD card, make a folder named andboot. Inside this folder you need to put the androidinstall.tar that you downloaded before. Also on this folder, you must put every needed androidupdate.tar. This TARs can have anything inside, from Google Apps, to Kernel Modules, and many others. If you're using the suggested rom, you don't need gapps nor the androidupdate.tar that came with the kernel. It contains modules (drivers) for the hardware, but Scoot CM7 RS3 already has them. It also has the basic google apps (gmail, calendar etc) inside, so you really don't need a androidupdate.tar for now. If you choose another rom, more ancient than the kernel above, you might get a error during boot that you're missing the kernel modules. Or you might also have Android without Gapps. If that happens, flash the Androidupdate (instructions further down).
All is set, and you're ready to flash. Before you continue, remember, you must have Hard-SPL installed. You are also doing everything bellow this point at your own peril.
4. With the SD card on the kaiser, press and hold the camera button while you power on/reset the device. You will be greeted with a screen where you can press the Power button to flash KAISIMG.NBH. Do it, and wait for the progress to finish. After it's done, wait a few more seconds, and reset the device. Kernel flashing done.
5. Pay atention to the boot, you'll receive a message "press vol up or d-pad center for menu". Press the D-Pad center and hold it until you get the replimenu. Here choose Install System. Be sure that the little * is on "Sys on NAND" and "Data on NAND" (it should be). Choose yes on the following 2 prompts. Pay attention to the screen, look for errors. You might receive out of space errors. If that happens, you're using a ROM way to big for the Kaiser, or you have too many Bad Blocks. If no error, you'll be back at the replimenu, choose quit.
Now Android should resume the boot process. After this point, is up to you. Configure it and tweak it for your own taste.
Annex A. Androidupdate.tar There are many reasons to need a androidupdate.tar, we are not going to dwelve in that, but an explanation will follow:
Acess the replimenu, reboot or power on the Kaiser and press D-Pad center when prompted. In the menu, there's the option "Install Update". Choose it, it will install whatever is in SDCARD/andboot/androidupdate.tar. Pay attention for errors during install, and after that, exit the replimenu to continue booting.
Annex B. Panel Type It's impossible to guess what's the brand of you panel type. If when waking the Kaiser from sleep, or perhaps when scrooling, you get strange artifacts or weird colors, you have the wrong panel type.
Open the KAISIMG-PANEL2-320-TILT0.NBH with atools.py, chose another panel maintaing you other settings, save it to the root of the SD card and power on/reset the Kaiser while holding the camera button to re-flash the kernel. There's no need to re-flash the entire Android for this.
