Thanks (to all).

It is far from complete though, and it will be an on-going work-in-progress. It's not as easy to write up general info as it is to write up a step-by-step guide...

Awesome post. This should see a few overwhelmed users right

Top work!

Incredibly useful and much needed thread, really well done, efrant. Information desk and referral center for new users. Wish it was here when I came onboard. You should make a "N00b Lighthouse" graphic for it. I think this will help reduce and untangle a lot of the repetitive new-user threads.

Awesome source of information. This needs a sticky ASAP.

this is one of the best guides i've seen. great work efrant. i hope this would be stickied for all

toro partitions

---

Great thread, efrant. Thanks for the effort. I'd love to see this stickied.


You mentioned toro/toroplus having a "radio-cdma" partition. I can't find it; perhaps it is a virtual partition that recovery and the fastboot know about that does not exist separately in storage. Perhaps it's hidden inside another one.

I'd like to contribute the partition list from my "toro" (Verizon Galaxy Nexus) in case is is useful. In addition to the named partitions listed in the OP, there 5 more unnamed ones. I don't know yet what they are used for.

mtdblock0    - (don't know)
mmcblk0      - (don't know but it looks big; like the entire eMMC)
mmcblk0p1    - xloader
mmcblk0p2    - sbl
mmcblk0p3    - efs
mmcblk0p4    - param
mmcblk0p5    - misc
mmcblk0p6    - dgs
mmcblk0p7    - boot
mmcblk0p8    - recovery
mmcblk0p9    - radio
mmcblk0p10   - system
mmcblk0p11   - cache
mmcblk0p12   - userdata
mmcblk0p13   - metadata
mmcblk0boot1 - (don't know - blank on Galaxy Nexus, but other devices use this)
mmcblk0boot0 - (don't know - blank on Galaxy Nexus, but other devices use this)

I would love to learn more about the bootchain, as I'm sure several of our unknown partitions are involved.

Great job on this efrant, thread has been stickied.

We have too many stickies in general as is so I just added a redirect for it in Q&A.

Damn man. This is fantastic.


Thanks for taking the time!

Thanks for the correction. Post edited. I wasn't entirely sure (as I don't have a toro or toroplus devices). Based on what I've read, I'm gathering that the LTE radio likely resides on the radio partition, along with the 3G radio.

And yes, I'm pretty sure you are correct: the mmcblk0 is just the entire NAND. Not sure what mmcblk0boot0, mmcblk0boot1 and mtdblock0 are.

I would also like to know more about the boot chain. I will try to do some research as time permits. From what I've read so far (and most of it is from AdamOutler -- see this thread), there is a chip that is not flashable which contains the intial boot program, which then loads the xloader, which in turn loads the sbl (which provides the odin and fastboot interfaces), which then loads the kernel.

..great work efrant, as always.

If I had a dollar for every time this thread gets a link reference in answering questions...
