[GT-N7000][REF] Service Manual and Full Schematics

---

Samsung Galaxy Note (GT-N7000/L) Service Manual + Full Schematics.

After having spent considerable time trying to find any half-descent schematic of the GT-I9100, I was pointed to a Google search-link (thanks to an anonymous source) and came across the full schematics of the GT-N7000/L. This was a lucky strike since the only schematics for the I9100 that I could find, was encrypted, as I posted here. Why so? Because it is very similar in hardware and design to the GT-I9100.

We are interested in better understanding the hardware in this phone, so that we could (a) develop unbrickable-mod, (b) communicate with phone modem via a virtual serial interface over USB and/or from a local shell and (c) get proper and early debug output for development purposes. But there are many more good reasons...

So, in addition, I decided to put together the messed up pages for the Service Manual, in the right order together with the schematics.

So here you go (the combined):

Samsung Galaxy Note (GT-N7000/L) Service Manual
+ Full Schematics.

This download consists of 2 PDF files compressed with 7zip:

Samsung_GT-N7000_Service_Manual.pdf
Samsung_GT-N7000_Schematics_Rev_07b_20110925.pdf

PS. The parts list should be somewhat similar to that of the GT-I9100 and if not, you may recreate it, using my script in the GT-I9100 Hack-Pack Add-On.

Hope this helps!

Apparently the schematics are not so "full" as I claimed previously. There are many missing pieces, although they show some of the most important connections. Sorry about that! (I will have to leave the title as is, in order not to screw up the search engines and other links.)

In addition it is worth noting that:
a) I have good reasons to believe that some component labels are screwed up, including the block diagram, as usual...
b) The similarities to the GT-I9100 are more limited that thought.

I Was Looking For the Service Manual. Thanks a Lot For Your Effort.

Some interesting and useful excerpts.

The Application Processor (Exynos 4210) boot pins/modes:




The Baseband Processor (Intel XG626) boot pins/modes:


The Voice Processor (Audience earSmart™ eS305) Known as U207 and also used in the GT-I9300:

Bad news regarding "Unbrickable" on these devices - even on Exynos devices where the proper xOM resistor combo has been found, a critical piece of the puzzle (a USB-bootable IBL that does not enforce signature checks of the next step of the boot process) is missing.

Rebellos and company have it for Hummingbird but not Exynos - this is why Unbrickable does not currently exist for any Exynos device.

There's got to be a way to circumvent that. But I have not followed that development very closely as it involves quite a bit of RE. Who's working on this (other than rebellos) ? What is the progress if any?

Who was working on that except me was AdamOutler. But actually work stalled, as Samsung locked Exynos more than S5PC110, they don't answer any technical questions. And at all I've got no time nor skill to look for deep hidden security holes in Exynos iROM.

I have also yet to see anyone compromise a device at this low of a level - all OMAP attacks have been farther down in the chain of trust. Same for the VZW GS3 - it doesn't check recovery signature on boot so that leaves a wide open hole.

THANKS

Perfect, thanks!
