[AT&T Samsung Galaxy S 4 Q&A, Help & Troubleshootin] rubsnick:
My S4 is on it's way and the one thing I think that's better on my old phone is the tethering options. I have an inspire 4G with AOKP 4.2.2 and I use bluetooth tethering for my nexus 7, I also use USB tethering for my laptop. Very rarely do I use Wifi. But I want to know how can I do bluetooth and USB. It's very important that I'm able to do this because I work online and sometimes my internet is less then reliable and have to rely on my phone occasionally. Once I root this mofo, How can I do this? What works what won't work. I'm tempted to do the alteration to wifi tether I saw in another forum using the S4's stock wifi tethering but I'm not sure if I can revert the phone back to normal. I mean if I **** it up can I just flash a stock rom in odin or what?

I think he/she is saying he/she wrote some length of zeros to /dev/block/mmcblk0 and is now in possession of a N7 brick.

The rest of it is sort of stream-of-conciousness documentation of efforts to figure out how to rescue it from that situation.

Scary thing is I understand most of what he/she is saying. Quite a bit of effort put in to this, actually.

I hope she/he succeeds. If there is anyone else working on cracking APX/nvflash/tegrarcm, they are doing so silently... so I am happy to see that someone is trying.

I am on the same boat as Sgt. Meow, but you mentioned doing a back up of all the partitions. In what format did you do this? Using what? It sounds like you got NVflash to work or at least do something. If that is the case and your backup is a .img then you should be able to push that to mmcblk0p0 and have a working device again.

Ok, so since you used dd to make an image of your chip, you should be able to use NVflash to write that back to mmcblk0. I don't know that reflashing the entire chip has ever been done, but reflashing individual partitions via NVflash has been done and is a great way to de-brick.

I can restore from backup, when I'll get sbk
[Nexus 7 Q&A, Help & Troubleshooting] androidfr33k:
As bftb0 said, how can you even use nvflash on the N7's? Can I use the dd command on a working N7 that has CM 10.1 and twrp in apx mode to save the boot partition or the bootloader and also get the sbk?

Is there really any way to retrieve the sbk on a working N7 to date? So far I think everyone has been unsuccessful, and I have posted on several threads about on how to restore by other methods such as jtag? I think even with jtag if I could access it on the mainboard and be able to use it, I would still need complex script/software. I don't think anyone is ever going to be able to figure out how to get nvflash to work on our devices!!
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
osm0sis has a thread / script in these (XDA N7) forums which allows altering lock state of an individual tablet by capturing/writing the bootloader partition using dd as you describe. But the catch is that every device performs this operation in a unique manner combining the sbk with a device serial# to uniquely encrypt/sign the boot loader - so you can not capture it from a working tablet and write it to a different (bricked) tablet.

Also, the sbk is not stored in flash memory - the flash memory is considered to be "untrusted media" by the processor. (That's what the patent documents that the OP provided links to describe)
[Nexus 7 Q&A, Help & Troubleshooting] androidfr33k:
Can I capture it on my working tablet to use if I brick my tablet (same tablet)? If so then that is a great tool!!
[Nexus 7 Q&A, Help & Troubleshooting] bftb0:
Yes you may capture it, No it is not for brickings (due to chicken-vs-egg issues).

http://xdaforums.com/showthread.php?t=2068207

The purpose of it is primarily to allow unlocking/relocking of the bootloader without wiping the user data partition.

Since it does this by writing the appropriate partition from a booted kernel (either OS or recovery), it clearly is not for "bootloader got messed up" bricks.

I mentioned it in the context of this thread (it's a little off-topic) because the devs involved had noticed in the course of their work that the binary blob of data for the bootloader is uniquely encrypted for each tablet. This is consistent with the process shown in the (.pdf) Patent filings that the OP provided.

I haven't tried it yet, so I can't vouch for it, but others have (but note the thread date, too - probably before v4.18 boot loader - I also don't know if that is significant or not). Doing this is on my "to do list", though.

Does any one have wheelie for linux with debug symbols, not

[Nexus 7 Q&A, Help & Troubleshooting] xornibblovsky:
For now, I realized, what my first experiments was with wrong assumption.

It wasn't different sbk keys. It was different nvflashes. Some of that nvflash's

has additional commands related to diagnostic . And only one of them has

a function like --sbk. Then I analyzed USB session, trying to catch

The logic of that generation of sbk from CSSN. I even tried to run another

related programs like tegrarcm, and still looking for some small loader like

minikernel that I saw for different model. I saw some logs and found checking

of 16bytes bashes at startup of that kernel.

For know I understand much better how nvflash working

with the device, but some functions not working like expected.

With help of gdb it much easy to undersand the logic of reflashing

and how CSSN used in that process. But I need

to capture USB session of reflashing the device. And I need to know CSSN.

And I have some ideas about AES and blobs. I'll explain it later.

For now I need some owner of TF201/TF300T/TF700 , Who do not

afraid to reflash the device under Linux, and know wireshark and gdb.

Is APX mode also available on the New Nexus 7 2013 (FHD), or is APX mode for the tegra 3? If so is there a better chance of getting the secure lock keys or is it the same deal with this device to?

THis is the QUuaComm S4 Pro and not sure what tool would be used for this SoC versus the Tegra 3.

Not sure about APX on the Nexus 7 2013. I tried to put it in that mode and I don't see say APX on the PC not do I see it do anything but the screen turn black.

So APX/NVflash must be native to the tegra 3 I have to assume?

You cannot use OpenSSL directly for AES encryption. I did diff of two blob files and found a standard header and footer in blobs. and then there is huge 2Mb data in between which is different. Probably that is AES encrypted. header and footers are common.

Hello christogouws!

I have managed to get my phone's screen onto my TV by using an MHL cable. Although it does not work on CM ROMs or any ROMs based on CM, it only works on Samsungs stock ROM or other TouchWiz ROMs. My personal favorite has always been RocketRom when it comes to TouchWiz ROMs and it works great for me with this version:

Rocket ROM Reloaded v1 thread on xda

also, Stunner works stunningly well! ;-P

I hope that you'll get the MHL working on your phone! Please don't forget to configure your TV to use the right HDMI port you are connecting the phone to, and so on...

Greetings,

Paco.

When I did the adb reboot oem-unlock command, the phone just restarted. I assumed this was because I have Ice Cream Sandwich which does not have the oem-unlock command.

I am sorry if I am asking a stupid question. I assumed the guides on here required the JB update which does have an unlocked bootloader apparently.

Is this the one to use? http://xdaforums.com/showthread.php?t=2198114. This one suggests that we should wait for JB update. Is there any way to manually install the JB update instead of going through what seems to be a difficult procedure?

As kevev said...

As kevev said, read a bit. Maybe a bit more.

Regarding qingz's answer to your Sprint information it is easily assumed that you were trying to use Sprint since you mentioned it. There are a lot of questions by a lot of people in a wide range of expertise. Always think of how what you ask will be perceived/interpreted by others to get the best answer for yourself.

Keep a humble attitude of learning and you'll go far, if not people won't answer our questions if we come off brash and know-it-all-ish.

To root, I just did using cmahendra's offline flashing method. It is easily on the first page of the L9 forum. It is a beast to accomplish, but go for it. Please note, when you get to step 11 you cannot "sit back with your hands folded behind your head" as it says, you have to go *back* to the original instructions and copy/paste a file. I share this because that part was not clear, and cost me about 5 or 6 hours of time with re-doing the steps over and over again.

Lost my Galaxy Note II with all my prototype film installed :( and now someone picked it up but no one's contacting me.

Was riding my motorcycle near my neighborhood for a meeting, dropped my phone and noticed it right away so I started tracing my way... checked google latitude and found out it was somewhere near my house. Went within the proximity, met who I think had it and asked around knocked and rang a few bells (11:30PM sunday night) and no one and nothing.

Verizon hasn't been much help, just told me file a police report and hope they contact verizon to request for them to track it. If anyone has any advice or even maybe familiar with the process verizon has to track a phone let me know. Since it's my work/company phone it's got a lot more value in it than the phone itself, along with my prototype skins, wraps and film. And last weeks pictures for our work of projects.

Lost in the La Mirada, CA area and was last tracked within my neighorhood. Phone is a White/Marble Verizon NOTE 2 with a Custom Carbon Fiber Backer and Custom Edge to Edge Protective film over the screen.

if anyone hears or has any input, I kindly appreciate it and thank you in advance.
