for the speedmod kernel, my opinion its better if you apply both. then the performance will boost. for the modem, better wait for gmhafiz @ freakfingers to explain to you. im using custom rom, and its fine to flash with custom rom.

They will not be affected.
No need to rename. When you are in recovery mode, choose "install zip from sdcard" and then "choose zip from sdcard"

Use volume rocker for up and down, back button to select.

must be 3e recovery

Well u need to enable 2e button recovery to use the file. For odin, u can use the same file, just need to extract 'modem.bin' and put it under 'phone'. Dont forget to unchecked for repartition. Also the rest of the field should be left untick (except for the phone).

Like i said, u need to extract the modem.bin from the file. Open the file>updates>modem.bin Select the modem.bin for phone and u are ready to go! No need to use tar although it is a zip file. Odin can recognize .tar, .md5 and .bin files. So no need to worry k!

Nope. Only the phone part

Hi. I really don't know where u did wrong. Maybe details please? I've tested it just now and it works. If u haven't flashed through odin before, u need to familiarize on how it works though. Btw im using odin 1.3.

Well basically both also requires u to use odin. So either is he installing 2e recovery or trying to install modem requires him to go through odin. But its true, flashing with 2e enabled is much easier (but still not fool proof).

i've failed to update to froyo using kies twice..
any solution guys?

already 100 % download the firmware but after that.. error message pop out on the computer..

Hi. I think i know where u did wrong. As i mentioned before, u need to extract modem.bin from the .zip file. U dont use the whole .tar file. Let say u wanted to use xxjpy modem.
1. Download XXJPY_Modem.zip from this link
2. Using winrar/winzip/7zip, open the file
3. Open updates. There u will find 2 files. Modem.bin and redbend_ua
4. Extract modem.bin to any desired location (eg. desktop)
5. Open odin, under phone section, browse for the modem.bin. It will automatically tick for the phone section.
6. Pit, re-partition, pda, csc, dump, phone efs clear and phone bootloader update should be left untick
7. From your phone, u need to enter download mode (vol down+home+power button)
8. Now connect your phone to computer
9. The computer will detect you hp (under ID:COM). Now all u need is to press start and wait till the whole process finished
10. When its done, your hp will reboot automatically and u can remove it from the cable.
11. For confirmation, u can enter *#1234#. If u managed to fully flashed the rom, your phone should be showing I9000XXJPY.

If u find it too difficult, i suggest u to install 2e recovery as mentioned by our fellow forumers. Its only a one time process and later if u wanted to install custom rom or flash different modem, no need to use odin. U can enter directly through recovery mode and flashed your desired .zip file.

Can delete the backup folder and logs. But leave others.

If not using voodoo lagfix (not enabled) can delete folder.

You can unroot it but required a full flash of the stock ROM.
