ClockworkMod Recovery for HD2 - FAQ
Q.1: Can I keep my Existing NAND ROM before I install CWM?
A.1: No, Backup with other method like Titatium backup before you install CWM.
Q.2: Can I keep my Existing ROM after I installed CWM?
A.2: Yes, You can create as many backup images of your system and data partitions as your SD Card memory space allows.
Q.3: I can not boot Recovery Kernel on SD!
A.3A:
1. Make sure initrd.gz and zImage is at root of your SD
2. Make sure aMAGLDR is set to boot from your root of SD. Use Services->BootSetting->AD SD Dir-> <.>
3. Try Boot AD SD again
A.3B:
1. create a /Recovery at root of your SD and place initrd.gz and zImage there
2. Set Services->BootSetting->AD SD Dir->RECOVERY from your aMAGLDR menu.
3. Try Boot AD SD again
A.3C: Try a different SD card with the method in A & B
A.3D: Upgrade to at least v1.3. Since v1.3 boot from NAND it remove SD compatibility issues.
Q.4: Can I flash NON CWM ROM directly into CWM?
A.4: Most Likely YES, but may depend on the ROM. just edit the flash.cfg that come with the NAND ROM.
for example:
original flash.cfg:
Code:
system ya|boot|ro filesize system.img
userdata ya|asize|hr allsize
For ClockworkMod 1.2:
change flash.cfg to
Code:
misc ya 1M
recovery ya|ro 5M
boot ya|ro 5M
system ya|boot|ro filesize system.img
cache ya 10M
userdata ya|asize|hr allsize
Flash it and this will be CWM compatible partition.
For Clockwork 1.3:
1. Upgrade to MAGLDR 1.13
2. Download 250M ClockworkMod
3. Create a Directory to unpack the 250M ClockworkMod files
4. Copy the system.img from the ROM you want to flash into that Directory. (because MAGLDR 1.13 is new. DAF include from the NAND ROM may not support the new rrecov and yboot flags.)
5. Modify the flash.cfg as following.
Code:
misc ya 1M
recovery rrecov|ro|nospr filesize recovery-raw.img
boot ya|ro 5M
system yboot|filesize system.img
cache ya 10M
userdata ya|asize|hr allsize
ClockworkMod use DAF too, the idea is to flash the ROM at the same time with a compatible partition for ClockworkMod Recovery.
You should try to keep system partition size to one of ClockworkMod presets (150M, 250M, 400M) when ever possible.
Q.5 I thought the system partition has to be 250M or 400M
A.5 Not really, It was set to ensure CWM style ROMS are compatible with each other without the need to repartition. However, if you are only interested in using CWM for backup your existing NAND ROM, there is no reason that it can't be between anything between 250M or 400M. I do however recommend if your system.img is close one of those numbers, keeping them at preset 250M or 400M will have better compatible with other CWM ROM. But since the backup is so easy. It's quite easy to flash a new partition then restore the img back without losing any data.
