Android

Bagian 1__

Handset ber-OS Android (contoh kasus kali ini HTC Dream atau G1) tidaklah sempurna tanpa adanya GMS (Google Market Service alias tempat pusat aplikasi baik berbayar maupun gratis) dan hak/priviledge sebagai super user (di Win-XP/WIN7 padanannya sebagai Administrator). Untuk ‘membebaskan’ handset Android yang masih ‘dipenjara’, perlu proses ‘jail-breaking’ (istilah iPhone) atau ‘rooting’ (istilah komunitas Android). Rooting ini bisa menjadikan handset Android dikuasai penuh oleh user.

Inti proses rooting:
1. Downgrade ke ROM/firmware yang mudah di-exploit (kasus tertentu tidak bisa downgrade, gunakan metode goldcard, contoh error 00028002 not allow)
Metode Goldcard (mencari sdcard “emas”):
+ Siapkan microSD (tidak semua compatible, satu merk lain kapasitas bisa lain hasilnya). Sebaiknya gunakan WinXP, saya coba berkali-kali gagal karena menggunakan WIN7, begitu pakai WINXP, sekali langsung berhasil.
+ Siapkan QMat terbaru versi 5.06
(http://revskills.de/pages/download.html) dan HxDex
(http://download.cnet.com/HxD-Hex-Editor/3000-2352-10891068.html?part=dl-HxDHexEdi&subj=uo&tag=button)

+ Download terminal emulator dari Market, masuk ke aplikasi, seharusnya muncul tanda $ (belum jadi superuser (tanda #) karena belum di-root).

+ Pastikan SDCard terdeteksi dari Android Anda (bukan sedang dalam mode drive di PC).

+ Di terminal emulator, ketik: cat /sys/class/mmc_host/mmc1/mmc1:*/cid dan tekan enter (akan muncul cidnya). Untuk menyimpan jadi file txt, gunakan perintah: cat /sys/class/mmc_host/mmc1/mmc1:*/cid > /sdcard/namafile.txt dan tekan enter, maka cid akan bisa dilihat di file namafile.txt yang ada di sdcard. CID berupa kombinasi angka dan huruf kecil sebanyak 32 karakter.

+ Buka QMat, pilih Crypto Analys – Crypto Toolbox. Kopi 32 karakter CID ke kolom sebelah kirim “Reverse String” (tidak perlu mengeset parameter yang ada), klik tombol “Reverse String”, maka akan keluar hasilnya.
Contoh: CID = 02544d5341303247039c820781009322, hasil reverse string: 23209107820c8397024031334d54425.
Note: jangan gunakan pedoman reverse string “manual”, contoh dari 1b534d303030303010b1a362de008310 menjadi 108300de62a3b11030303030304d531b. Gunakan hasil dari QMat.

+ Copy paste hasil reversed string dari QMat ke http://revskills.de/pages/goldcard.html (jangan lupa masukan email yang valid dan saat itu sedang aktif dibuka agar email yang berisi goldcard.img dapat langsung digunakan). Langkah ini akan sering diulang2 jika belum mendapatkan SDCard yang cocok. Sangat beruntung jika langsung mencoba langsung berhasil.

+ Mount SDCard agar terbaca di komputer.

+ Buka HxDHex Editor. Pilih menu “Extras”, pilih “Open disk..”, di bawah bagian “Physical Disk”, pilih “Removable DiskX” (X disini bisa berari penomoran tergantung banyaknya removable Disk Anda yang sedang terkoneksi. Agar lebih yakin, pastikan hanya Android yang sedang konek ke PC Anda).

+ Pilih menu “Extras” kembali, kali ini pilih “Open disk image…”, arahkan ke file goldcard.img yang kita dapat dari http://revskills.de/pages/goldcard.html. Pilih 512 (Hard disks/Floppy disks).

+ Di tab “goldcard.img” Copy semua (CTRL + A kemudian CTRL + C, atau klik edit klik select All klik edit lagi klik copy)

+ Di tab “removable disk”, blok semua angka dari offset 00000000 sampai 00000170, klik edit, klik Paste Write (CTRL + B).

+ Save, tutup HXD.

+ Coba akses kembali SDCard Anda di PC. Kalau perlu, remove dulu (unmount), kemudian mount kembali. Jika SDCard Anda masih bisa diakses dengan baik, maka metode goldcard berhasil 75% (harus dipastikan kembali apakah sudah bisa flash atau belum). Jika minta format disk, berarti SDCard tersebut tidak bisa digunakan sebagai goldcard, lupakan, coba cari yang lain😀

Flash dengan DREAIMG.nbh (bisa gunakan RC29 atau RC7):
+ Tekan tombol power bersamaan dengan tombol kamera, tahan beberapa detik kemudian lepaskan. Dream akan masuk mode bootloader. Tunggu, jika masih keluar error 0028002 not allow, itu berarti Anda harus mencari kembali goldcard yang cocok. Jika berhasil, akan muncul pilihan “tekan power untuk lanjut” atau “tekan trackball untuk cancel”. Tentu saja tekan power karena kita akan flash dengan ROM 1.0 biar bisa rooting🙂

+ Tunggu prosesnya sampai ada keterangan “press home + back to reboot”. Tekan tombol home bersamaan dengan tombol back beberapa detik kemudian lepaskan. Dream akan reboot dan masuk proses biasa.

+ Jika sudah bisa masuk ke welcome screen (robot ijo) dan ada perintah untuk sentuh robot ijo, berarti sudah berhasil. Ikuti saja prosesnya seperti awal (verifikasi account google kembali). Jangan lupa setting APN dengan menekan tombol menu kemudian klik “APN Setting”. Isi parameternya (kalau telkomsel cukup isi nama dan apn saja).

+ Jika berhasil akan masuk home screen, buka keyboard Dream, ketik langsung “telnetd” (akan mencari kontak, biarkan saja).

+ Klik Market (harusnya ada), search “terminal”, akan muncul satu-satunya terminal emulator😀 Download dan install

+ Masuk terminal emulator, konek ke localhost port 23, jika berhasil akan muncul tanda $

+ Ketik di terminal emulator:
mount -o rw,remount -t yaffs2 /dev/block/mtdblock3 /system [ENTER]
cd sdcard [ENTER]
flash_image recovery recovery.img [ENTER]
cat recovery.img > /system/recovery.img [ENTER]

+ Proses berikutnya tergantung Anda akan flash dengan file recovery yang mana (JF atau Cyanogen)…

Note: File recovery.img disesuakan nama filenya. Kalau untuk Cyanogen, nama filenya cm-recovery-1.4.img (contohnya).

    I was curious if you ever considered changing the structure of your blog?

    Its very well written; I love what youve got to say.
    But maybe you could a little more in the way of content so people could
    connect with it better. Youve got an awful lot of text for
    only having 1 or 2 images. Maybe you could space it out better?

    What a data of un-ambiguity and preserveness of precious
    know-how regarding unexpected feelings.

    found out so far. However, what concerning the bottom line?
    Are you sure about the source?

  10. Maret 6, 2014 pukul 7:56 am

    After I initially commented I appear to have clicked on the -Notify me
    when new comments are added- checkbox and now every time a comment is
    added I receive 4 emails with the exact same comment.
    There has to be a means you can remove me from that service?
    Thanks!

    Howdy just wanted to give you a quick heads up and let
    you know a few of the pictures aren’t loading properly.
    I’m not sure why but I think its a linking issue.

    I’ve tried it in two different browsers and both show the same outcome.

  13. Maret 30, 2014 pukul 7:21 pm

    I like the valuable info you provide in your articles.
    I will bookmark your blog and check again here frequently.
    I’m quite certain I’ll learn lots of new stuff right here!
    Good luck for the next!

  14. April 3, 2014 pukul 11:46 pm

    It’s an amazing piece of writing for all the internet viewers; they will get
    benefit from it I am sure.

  15. April 3, 2014 pukul 11:50 pm

    Spot on with this write-up, I seriously believe this site needs far more attention.

    I’ll probably be returning to read more, thanks for the info!

  16. Juni 5, 2014 pukul 9:09 am

    Aw, this was an extremely nice post. Spending some time and actual effort to
    generate a great article… but what can I say… I put things off a lot and never manage to get nearly
    anything done.

  17. Juni 12, 2014 pukul 9:48 pm

    Have you ever considered about including a little bit more
    than just your articles? I mean, what you say is valuable and everything.
    Nevertheless think about if you added some great images or video clips to give your posts more, “pop”!
    Your content is excellent but with pics and videos, this
    site could certainly be one of the most beneficial in its
    niche. Awesome blog!

  18. Juli 9, 2014 pukul 8:34 am

    Its like you read my mind! You appear to know so much about this,
    like you wrote the book in it or something. I think
    that you could do with some pics to drive the message home a bit, but instead of that, this is excellent blog.
    A great read. I will certainly be back.

  19. September 2, 2014 pukul 9:22 pm

    This blog was… how do you say it? Relevant!! Finally I’ve found something that helped me.

    Appreciate it!

  20. September 18, 2014 pukul 9:28 pm

    With havin so much written content do you ever run into
    any problems of plagorism or copyright violation? My blog has a lot of
    completely unique content I’ve either written myself or outsourced but it looks like a
    lot of it is popping it up all over the internet without my
    authorization. Do you know any methods to help stop content from being
    stolen? I’d definitely appreciate it.

  21. September 20, 2014 pukul 1:43 am

    Greetings! Veryy useful advice within this post!
