[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
Hi, I was trying to update my nexus 7 from fastboot, one of the fastboot commands for the bootloader gave an error. So I tried to reboot and again same error, so stupid thing I did and I turned it off from the bootloader (when the device was still on). now the device is not responsive, it doesn't turn on or have any reaction. I'm familiar with unlocking bootloader and all the android stuff since the first day of android, so my nexus 7 doesn't have any bootloader in it anymore (at least not a proper bootloader. in the device manager when I plug it in, it shows as a device called APX. can anyone help me get turn it on. as far as it turns on I can handle to flash it with some code lines. but I have no idea how to bring a bricked nexus 7 to life.

and if it helps so far googling I ended up with a program called QPST. if anyone help me use it I think I can bring it to life

I'm even considering donating if anyone help me succeed, cause for one fact I know this device is not coming to life easily
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
welcome I have the same problem been looking everywhere. Have you got the 2013 because i think qpst is for qualcomm chipset
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
I have the old nexus 7, and I have tried even nvflash, I can communicate with my device through USB but I need someone who knows better to give me (us) the right files so I can push the data to the device, maybe search for nvflash or nexus 7 blob.bin file if you have never heard of it
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
Nexus 7 blob.bin is device specific, but if we can find someone who can give us their blob.bin file I think I found a way to make it work on any device
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
I don't know why this hasn't already been given a go, for some reason is like people are stingy with their blob.bin
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
Hopefully someone will see this and if we get lucky they will post theirs for us.

I don't know about you but I'm taking a risk of detaching the memory part from the motherboard reprogram it with the boot data and re attach it to the board again. seems like a crazy idea but its better than another 300$ to buy a new one
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
I'm not that advanced. I downloaded the cardhu driver package directly from nvidia website which seems to have lots of interesting files including nvflash I don't know if you already seen but I used this to get my uid which never happened with anything else, maybe if looked at by someone with more knowledge can pick something important from there. I know someone who solved his problem since he had a blob.bin his post is on here aswell you could ask him and take a dig, I wouldn't know what to look for
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
I figured out how to fix it with blob.bin for own device, without my blob.bin I found a generator from acer tablets which generates your device encryption to use someone elses blob.bin using your UID, UID is a good choice. but if you've used costume roms before, there is 50% chance your UID have been modified from the original one. I don't know how it happens, but it did for me in past.

by the way you can read your original UID by just opening back of the nexus 7, its written inside the back of the tablet on the lower part near the speakers
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
So that means we just need an already made blob.bin. well getting a blob.bin won't be hard, I'll ask around since there are lots of people who backed up their blob.bin
[Nexus 7 Q&A, Help & Troubleshooting] GedBlake:
Hi, mehras1991...

Here is my 'blob.bin' (and other associated files) that I generated some months ago, using the

flatline

procedure.

https://dl.dropboxusercontent.com/u/37483979/blob_bin.zip

The files in this .zip archive were generated from a WiFi only Nexus 7 2012 model.

Hope this helps... but to be honest, I'll be very surprised if it does... as bootloaders are crypto-signed to a specific Nexus 7.

Rgrds,

Ged.
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
thanks, probably after maybe a day or whenever I get result I will post a reply, let's hope the trick I have in mind works, cause I'm gonna modify the blob.bin
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
good luck, gonna have my fingers crossed so tight they gonna break.
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
I'm so angry that my friend was traveling I check with warranty so I sent it with him for repair.

I'm so angry that I found a blob.bin extractor tool, and I found a way to replace my device's encryption on the other blob.bin file. but unfortunately I don't have my nexus 7 with me anymore... :mad: :crying:

on the plus side I'm pretty sure they're gonna give me a new nexus 7
[Nexus 7 Q&A, Help & Troubleshooting] tzarp990:
Well that sucks. Can you give me references so I can have a go?
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
this is where I got creative about doing it to play with the blob.bin

https://github.com/AndroidRoot/BlobTools

and I had no idea this thing exist
[Nexus 7 Q&A, Help & Troubleshooting] mzanette:
I have my friends Nexus 7 in a currently corrupted boot loader state so it shows up with APX on windows. I downloaded the blob.bin from this thread but to be honest I have no idea how to modify it using this nexus 7 UID. Any chance you can help me try this? Device is already bricked so I have no worries about doing further damage to it..if I can get it alive again it'll be worth the shot.
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
I drooped my last researches on how to use someone else's blob.bin with my old laptop and alot of other real life projects, if you have another nexus 7 blob.bin I suggest you give it to repair or find something else to play with. if you have your own device's blob.bin, you can find here how to do it

https://www.androidroot.mobi/pages/guides/tegra3-guide-nvflash-jellybean/
[Nexus 7 Q&A, Help & Troubleshooting] mzanette:
Yeah, I was able to backup my own blob.bin using the instructions. Still doesn't help me with the bricked Nexus 7 though. Why do they need to make it so difficult? There should be a generic blob that would let u recover a device, or at least a utility to generate a valid blob file knowing only the devices's UID.
[Nexus 7 Q&A, Help & Troubleshooting] mehras1991:
so if you have your own blob.bin what's the problem, you can easily recover it with nvflash, just incase your computer doesn't recognize the dead device, don't plug it to a USB 3, it just makes it harder for you to resolve it. when you plug the tablet doesn't turn on, but your computer see the usb port open. and don't leave the tablet pluged to laptop alot, since the tablet can't be charged at this stage, if it runs out of battery then you also have to replace a new battery to boot it up the first time.
[Nexus 7 Q&A, Help & Troubleshooting] mzanette:
Yeah maybe I wasn't clear. I have two Nexus 7s...my own which is fine and backed up bin files, and my friend's dead Nexus 7 which is a different tablet and I DON'T have the blob.bin for that one.
[Galaxy Note 10.1 (2014 Edition) General] Scott:
I created a spot on my website for the stock Odin Tar's that I use for the P600.

I posted the US / XAR Region Stock Odin. I also posted the ML1 Asian base I used as well.

As I gather newer ones I will put them up and updated this thread.

Although this guide is written for the p600 it would, in theory work on any P60x device so long as you have the proper Odin files!

Note: This will not "untrip knox"!!!!!!!!

Here is the download page on my site:

MOD EDIT: Link removed as domain has expired. Thread closed until new links can be installed

[Galaxy Note 10.1 (2014 Edition) General] Scott:
How to Return to stock

This mini guide assumes the following...

You were able to root and or install a custom recovery or ROM therefore the drivers are installed on your PC for the tablet. So here we go...

Download Odin from the links in the OP

Extract the the .md5 file from the zip file you downloaded above.

Boot tablet into "Download" mode. You can do this by holding Power and Volume - (down) when the device is shut off. I note on this device it can be a little trickier so you may have to try a couple times. You should now see this on your tablet

Connect Tablet to PC using known good USB Cable

Start Odin and Press the "AP" button to load the tar.md5 file. This may take a minute as it is also calculating the MD5 to ensure you have a good file. A bad file means bad issues and it wont let you flash it (good fail safe).

Once Odin sees the Tar and loads it completely AND Odin sees the tablet press the Start button to begin. Can takes about 5 to 10 minutes so be patient. Do NOT check or uncheck mark ANY other Options in Odin unless you know what you are doing!

Once it complete you will have a factory image on your tablet. Yay!

But we are not done. You may also want to, at this point, reboot to recovery and do a full data wipe. This method of Odin leaves the SD card and user data intact. To get into recovery hold Power and Volume + until you see the stock Android recovery. Select format Data, reboot. Boom, your tablet is like brand new!
[Galaxy Note 10.1 (2014 Edition) General] Scott:
Guided added!

I am not the best technical writer so if you need help understanding what I am saying dont hesitate to ask!
[Galaxy Note 10.1 (2014 Edition) General] Scott:
Bumped so people can find this...

Mods moved it so no one looking will actually see it...
[Galaxy Note 10.1 (2014 Edition) General] Vexelius:
I'm glad you bumped it. I still haven't tried to install any custom ROM in this tablet, but this post will sure come in handy soon!
[Galaxy Note 10.1 (2014 Edition) General] Scott:
Indeed!
[Galaxy Note 10.1 (2014 Edition) General] kaneelias:
What happens if I failed to root (according to TWRP) and am stuck in the Samsung splash screen? I was obviously able to install TWRP so hopefully that is enough for Odin to get me back to stock

Will this work?
[Galaxy Note 10.1 (2014 Edition) General] Scott:
If you can see samsung screen you can odin back to stock.

The directions I posted should hold true about getting to Odin / Download Mode
[Galaxy Note 10.1 (2014 Edition) General] ChrisNee1988:
Thanks for this guide, I agree, it should definitely be in the development section.
[Galaxy Note 10.1 (2014 Edition) General] tahrang:
Hello

So will I get the OTA updates after this? How do I untrip knox?

thanks
[Galaxy Note 10.1 (2014 Edition) General] sdelliott31:
Thanks for this Scott and a great ROM!!!!
[Galaxy Note 10.1 (2014 Edition) General] Scott:
Yes, this is returning you to stock like when you turned it on for the very first time.

No one knows how to untrip knox.
[Galaxy Note 10.1 (2014 Edition) General] starfall42:
Is it Knox that blocks the ota updates, or is it the rooting itself?
[Galaxy Note 10.1 (2014 Edition) General] Scott:
Not sure. Never tried to Ota with KNOX.

Maybe ask in the Q/A forums.
[Galaxy Note 10.1 (2014 Edition) General] abdielol:
Just to be safe, and If I do this the tablet will be as if it was completely new, right? I'm going to exchange it for another one and I want to be sure it's as new. Are there any flash counters or stuff like that I should be worried about?

Sent from my Nexus 5
[Galaxy Note 10.1 (2014 Edition) General] GldRush98:
So when a system update comes out we could use these directions to flash the stock rom with out loosing data, apps, settings, etc? Then be able to get the stock OTA?

Coming from the Nexus world, This is a bit different. Google seems to have no interest in the 10 inch sector though, so here we are.
[Galaxy Note 10.1 (2014 Edition) General] BclingergFJ:
Never have we had a tablet so heavily defended with so many issues. 6 tablets and this one stands out.

[Galaxy Note 10.1 (2014 Edition) General] iTelegraph:
Tripping out?

I think I understand what you are saying, but I'm new to Android, and would appreciate a sanity check::cyclops:

1. Knox "trips" (i.e. opens a fusible link in the hardware) if you root the tab and (or?) boot with a non-factory ROM. Once it trips, it cannot ever be "untripped", even if you return to a factory ROM image. (Hence the emphatic statement in the quote.)

2. Question: If a tablet is currently, and has always been, unrooted and stock, will using Odin and these instructions with a factory ROM trip knox? For example, to upgrade to the factory KitKat image

3. Follow-up question: If I flash KitKat as above, can I return to the original release by following your guide, again without tripping knox?

Thanks for the guide and software, and for your help.
[Galaxy Note 10.1 (2014 Edition) General] jherring002:
1. As far as anyone knows, Knox cannot be untripped.

2. If you Odin a FACTORY IMAGE it WILL NOT trip Knox. Only custom roms/rooting trips AFAIK.

3. I'm not 100% sure as I haven't tried, but I think I've seen discussions where the bootloader wasn't changed so you could go back. Again, I'm not 100% sure. Maybe we could get clarification from someone who tried.
[Galaxy Note 10.1 (2014 Edition) General] blinkingled:
This doesn't work for downgrading from CND2 - fails with SW REV. CHECK FAIL DEVICE: 3, BINARY:2. I was hoping to fix my ChromeCast issues with CND2 by downgrading.
[Galaxy Note 10.1 (2014 Edition) General] iTelegraph:
Thanks so much for the clarifications. I guess using Odin isn't quite like flashing the BIOS on a PC, where you can flash any version, forward or back.
[Galaxy Note 10.1 (2014 Edition) General] jherring002:
Nope. not that easy sometimes.

Galaxy nexus are super easy to go back n forth, but Samsung does something to thwart that. Thats the way I understand it anyways.
[Galaxy Note 10.1 (2014 Edition) General] iTelegraph:
Thank you ... you've saved me a lot of grief. I was thinking of trying CND2 and returning to BMK1 if I didn't like it.

:confused: Frankly, I'm really confused as to why it is ok to downgrade from a custom ROM, but not from a different factory ROM. Maybe once knox is tripped, the system no longer cares what you do?;)
[Galaxy Note 10.1 (2014 Edition) General] hanspampel:
Custom Roms didnt flash bootloader. If you flash newer bootloaders, you can only go back to fws with the excact same bootloader, otherwise it failes in Odin.

Thats not totally correct. Some failed flash updates via Kies trips knox too. Ive read about some devices.
[Galaxy Note 10.1 (2014 Edition) General] jherring002:
I haven't seen this. But I could see how that would happen. So just make sure you do it right? That would be the solution then? I'm not sure, I've never had a failed Odin unless I screwed something up
[Galaxy Note 10.1 (2014 Edition) General] elzeus:
So theres no way to downgrade to 4.3 after going to the official 4.4.2? I'm getting nasty lines on screen sometimes while playing video.
[Galaxy Note 10.1 (2014 Edition) General] iTelegraph:
Thanks for the explanation. I'm new to Android, so I apologize if my next question just shows my ignorance:o but since there are people who need to back up from KitKat...

Would it be feasible for a dev to create a version of BMK1 that used the bootloader for CND2?
[Galaxy Note 10.1 (2014 Edition) General] DirtDigler:
Here's how I fixed the "SW Rev. Check Fail. Device:3, Binary:2" issue. I was trying to take my device back to stock root.

I had to find the post KitKat tar file (which I did on the forum here) and flash that, it would not let me go back and use the file in this thread because I had already did an OTA update so you can't go backwards, at least I couldn't. I'll try to dig up the file I used and post it here.
[Galaxy Note 10.1 (2014 Edition) General] luis_juelipe:
question

U mean, returning to stock after installing a custom rom, right?

In the firmware file (tar) is included all the native programs of the p600?

I ask this cuz I rooted my note when it was on 4,3

the I unrooted it to upgrade it to kitkat

and now I have a very small battery life (even after doing a factory reset)

So i was planing of installing a custom rom to erase all data and then reinstall 4.3 by odin with the method u shared here.

do u think i could make it?

---------- Post added at 03:58 AM ---------- Previous post was at 03:49 AM ----------

So U were able to downgrade the tablet?
[Galaxy Note 10.1 (2014 Edition) General] buhohitr:
Return to stock means if you on stock 4.3 and use custom rom for 4.3 you could return to stock 4.3, same goes for 4.4, but once you on stock 4.4 and running 4.4 custom rom you can't return to stock 4.3, you can only go back to stock 4.4. The issue here is once you upgraded stock 4.3 to stock 4.4, your bootloader is upgraded which prevent you from going back to earlier version. It's not possible to go back so don't even try it you will brick your device.
[Galaxy Note 10.1 (2014 Edition) General] waywardfrantz:
download link broken

The download doesnt work at goo.im but theres just an extra / delete it and its fine
[Galaxy Note 10.1 (2014 Edition) General] notiones:
So, where can I find a flashable odin file for 4.4? It seems all I've been able to find is MK1.

I tried flashing the original, but I guess I upgraded to 4.4 somewhere in the past and now get the binary error when I try to flash the file in the OP.

Is there a Safestrap being developed for the Note II? Or have I completely missed it in my rummaging through the threads?
[T-Mobile Samsung Galaxy Note II] mattlowry:
I have only seen safestrap on Motorola phones. it may be on others but for the note 2 there is cwm, twrp, and phillz
[T-Mobile Samsung Galaxy Note II] Double0EK:
Safestrap might make sense for the 4.3 bootloader and knox. Having a safestrap

MIGHT

not trip the knox binary count.

It would work like this.. Flash a rooted 4.3 Firmware. Install Safestrap (hoping it wont trip the knox) and go from there....

Could be possible? Thoughts?
[T-Mobile Samsung Galaxy Note II] maxjivi05:
It should be possible considering the note 3 has the same locked setup and safestrap helped them a lot now if I could do that on the Note 2 that would be awesome. Amazing program.
[Moto G Q&A, Help & Troubleshooting] sargeta:
I recently bought a Moto G only to discover that my version (XT1033, the Dual SIM/16GB Brazillian version) doesn't have many (if any) custom ROMs avaiable (mostly because of dual SIM, I guess?).

Now, by lurking a bit I got mixed opinions.

Is it possible to successfully (with no serious bugs/issues) flash a custom ROM (say, Cyanogen 11) from a different version?

The idea I got is that Dual SIM won't work (since most custom ROMs are made for single chips). I don't really care about dual chip capability (I use only one), but I fear that I will brick/screw up my brand new phone.

I have a mild know-how on flashing/rooting and whatnot, my only problem is that Single/Dual SIM cards issue.

Thanks in advance.
[Android Q&A, Help & Troubleshooting] nikrou:
Hi all,

I want to build my own cyanogenmod port for my device (tablet). It's an Allwinner 13 tablet (inet 86vz)

I started following Doc:_porting_intro on cyanogenmod wiki (cannot post url) and everything seems good and now the step for testing recovery image is a problem.

I successfully build the recovery.img. I installed it on my device and reboot it in recovery mode. I can see the beautiful hat ! :) But nands partitions have not been found and cache partition had not been mounted. I watch /tmp/recovery.log and it's confirm that.

I'm not sure it is the fix, but inserting (with insmod) the nand.ko module solve the problem. My question : how can I automate that ? In which file ?

I didn't find another similary device.

Thanks in advance for any help.
[Android Q&A, Help & Troubleshooting] nikrou:
My device continue to go in bootloop. Don't know what to do or what information can be useful to find a solution.

Is there another way to try to port cyanogenmod to my device by small patch beginning with my stock rom ?
