[Q] Sideloading when unauthorized? - Android Q&A, Help & Troubleshooting

Hi all,
I have a Galaxy Nexus. I accidentally wiped the SD Card trying to flash back to stock, and now I have no OS. So, I'm trying to sideload a file onto the device but I'm getting an unauthorized message, as seen in the photo attached. I'm on a computer I've previously authorized, and I've tried one I hadn't, but both give me the same message.
Is there any way I can bypass this to get this file on my phone? Since I can't sideload through this, I've basically hit a wall.
My recovery is CWM, if it helps, but I've gone through every option and nothing seems to allow authorization.
I'd really appreciate any help, my phone's basically a brick at the moment

Don't own a galaxy nexus, but its my understanding that all galaxy devices have fastboot capabilities, if this is true why not flash a recovery that doesn't require authorization
Or if there is a download mode like other Samsung's, try hiemdal to return to stock
If there isnt a download mode than I would assume there is a factory image that could be flashed through fastboot, I'm sure all this info and more is easily searchable in your devices forum
Best of luck

I got it up and running, thanks for the help!
For anyone with the same issue in the future, my main problem was thinking I had to get past the unauthorized device message in order to sideload and use CWM to flash. I hadn't considered using fastboot to just flash stock. The Nexus Toolkit's back to stock option in softbrick/bootloop mode was able to reset to stock and get my phone up and running, after I reinstalled drivers.

Stock Bootloop - Help recovering data!

So out of nowhere, my Note II shuts off last night and I'm unable to boot. When turning the phone on, the SGNII splash screen shows up just fine, but then my phone will endlessly loop back and forth between the Samsung animation and the Verizon 4G LTE animation.
This phone has never been rooted and runs the stock version of everything. Now I would do a factory reset if it weren't for the fact that I have very important photos and videos of my grandmother who recently passed away in my internal storage.
I have tried going into recovery mode, clearing cache, trying to access the internal memory via USB, and nothing works. I desperately need to have a phone to use, but at the same time would rather go phone-less with hopes that I may be able to recover these photos. I have spent countless hours trying to recover this data or even fix the bootloop, but I can't seem to figure out a solution.
I know I am a noob on these forums and this is my first post, but I would GREATLY appreciate being able to recover any part of these immensely important photos. If anyone has a way to recover these photos, I would forever be in gratitude for sharing it with me. Thank you.

If you've never rooted/are stock, how are you in recovery mode? Are you sure you aren't in DL mode?
If you can access download mode/for some reason had debugging enabled/you could try running casual, wiping everything but the data, and installing a custom rom
Otherwise, your data might be gone unless you use a minisd or dropbox.

Then I pretty much think you are boned.
I don't know, but you could try reflashing the stock firmware in ODIN if you get that working.
Two things, there is a stock recovery in the phones so he can get into the stock recovery. Having said that I don't think a factory reset will erase photos. I know it didn't from a custom recovery and in pretty sure a stock recovery is the same

I understand I just never use stock recovery hopefully someone can come in who can confirm that for me and you. Also have you tried ADB while booted into recovery? I think it works for some phones

I tried ADB, but my phone wasn't being connected (and it was my first time using ADK on my Note 2). I don't know if that has anything to do with the fact that I never enabled USB debugging.
this is what you do
When messing with my phone 2 days ago I got into a bootloop were it flashed the 4g symbol repeatedly. Here is how I recovered everything and didn't loss pics or anything. I went through Odin and reflashed the system connected to my computer. Look up link to root the phone it should be about injected root and Odin follow all steps and back back to normal.

How were you able to root/flash with USB Debugging disabled? Do you have a link to a guide you could give me?

[Q] Can boot into a "black screen" recovery and get ADB feedback but that is it.

[Q] Can boot into a "black screen" recovery and get ADB feedback but that is it.
Strange issue I have here, well it is to me at least, my fathers SGH-I777 the AT&t model boots fine and works when booted but the play store gives me the "no connection" on both wifi and hspa+ and there are a few apps that do not work and cannot be updated for android 4.3 because of the play store. All that is just a day on android and would be fixable if recovery worked. It had or possibly still has clockworkmod recovery installed on it, no idea of the version unfortunately. The first thing that came to my mind was to just update it, well, it cannot be that easy as the latest version of ROM manager does not work, it crashes on startup. So I decided to try ADB and I will get this back if it is in its black screen version of recovery mode
Code:
C:\1>adb devices
List of devices attached
0123456789ABCDEF recovery
C:\1>
and this if it is booted into android
Code:
C:\1>adb devices
List of devices attached
0123456789ABCDEF device
C:\1>
Kind of a side note but also the main issue, when I try to "reboot to recovery" or hold both volume rockers and the power button till to logo appears all I get is a black screen and if it is dark enough in the room you can see that the backlight is on. So I am assuming a corrupted file somewhere, I just need to get somewhere and so far after 3 hours of searching for a solution today I have not. I don't know where to splice this in so i'll do it here; I am pretty sure this is a result of my father having Cyanogenmod updater update from 10.1 to 10.2 without completely re flashing boot and installing from a "factory reset" device then recovering the data.
List of some other things I have tried:
installing the latest apk of the play store
installing the latest apk of ROM manager
not much else that I can think of at this time, but ask and I will either try it or tell you if I have and try again anyways. Not too urgent but thank you for being here xda .
I just read this "http://forum.xda-developers.com/showthread.php?t=1824419" and it looks like rom manager is not a good idea, still need to find a way to install the recovery though and I have no idea how to get fastboot to work without it.

Put in normal download mode by pulling battery and hold the volume down button as you plug the micro usb in. Reflash to stock jelly bean 4.1.2 using Odin and root with framaroot 1.42 and use aragon exploit and go from there....

Just a couple of points, which may be helpful if you are not very familiar with the SGH-I777. Recovery is built into the kernel, not in a separate partition of it's own, so you can't just install a recovery, you must install a kernel containing a recovery.
Rom manager is said to be OK when you have CM on the phone, but in your case it would probably be best to avoid it until the problem is resolved.
The solution 4-2ndtwin posted sounds correct to me. If it were my phone, I'd try that first before flashing back to stock.

Can't get past first update

This evening i've made a factory reset of my nexus 9 and now i can't get past the first update because when it reboots it gives me the "error" that was giving when trying to update using the OTA. When i reboot it, it still tells me to update the device.
I have an unlocked bootloader so i think i should be able to flash the updated official rom from the bootloader but i don't know how and all the guides i've found told me to "select" things that i couldn't find.
I am stuck at the first update so i don't have the usb dabugging enabled but i still can load things using the usb.
Should i send it back? (The device was rooted but i think the factory reset should have removed it)
Please help me i'm desperate! (and sorry for my bad english)

Try flashing the factory image. This is for the n5 but will work for the n9. Look at method 2. Use the correct bootloader and radio names for the n9, they'll be different than the examples given. Also in method 2 there is one command that is different for the n9. Instead of fastboot flash userdata userdata.img use fastboot flash vendor vendor.img. Google nexus factory image for the factory image for the n9

Fastboot issue

Just got my N9 today. When I ADB devices, i see the serial # of my device properly. If I go into bootloader, when I fastboot devices, it comes up as all question marks (??????????????? fastboot). Windows properly sees my device as "Android Bootloader Interface". I am able to do basic commands (oem unlock, reboot-bootloader, etc). However I cannot push any files (root or custom recovery.) My DOS window just hangs and nothing transfers.
I googled for three hours and can't find if this is fixable or if I have to RMA. (And if I do RMA, how would I? I can't say I am having issues pushing custom recoveries to the device LOL)
Thanks in advance!
Have you tried flashing the factory image? That should not void your warranty

Then I'd say you rma it. Just tell them you didn't get the ota to 5.0.1 and you were trying to flash the factory image and nothing works in fastboot. You definitely have a hardware issue.
Just to be clear, when you tried to flash a custom recovery you fastboot flash recovery customrecovery.img?

I have the same problem that 'fastboot devices' return question marks. I have drivers up to date. I just checked on my friends PC and thank God 'fastboot devices' works on his PC. So I now wonder and think how could I debug that on my PC and get it working. Maybe go through some logs? Or export drivers?

Don't plug it into a USB 3.0 port. that was my issue all along. Use a USB 2.0 port.
It's a cable fault. In my Redmi 3 on a cable from old Xperia P i've had question marks,
replaced the cable to a newer cable from Redmi Note 2 and voila - the correct number displays instead of the question marks.

Samsung S3 memory full

My work colleague is an idiot - Despite warnings from his S3 that phone memory was low he continued taking videos and pictures and he has no sd card in the phone. Now the phone boots up but the pattern unlock screen is unresponsive. I offered to try to help him as he said "The last 2 years photos of my life are on there" so clearly a factory reset will lose them all so that's not an option.
So I installed Kies, thinking I'll just grab them to my PC for him - but alas no. MTP USB driver installation fails every time and yes I've googled my socks off, tried all the regedit fixes, even tried installing Win 7 32 bit on a spare hard drive.
I've checked that the ribbon connector for the screen is attached, tried linux boot disks that don't see the phone and now I'm all out of ideas. Any help would be vastly appreciated :fingers-crossed:
Hello,
Welcome to XDA.
Most of the time the screen being locked wont let PC interact with the device. There are many different models of S3, give me your model number and I'll guide you to where you can find answers.
You may can flash a custom recovery or a temporary recovery(not sure because I don't know what is available for the model you're working with and what isn't), if you can get one of those recoveries then you may can use the factory reset in recovery(it wont wipe his photos) or adb to get the phone working.
Remember to create an XDA account so you can post and reply in the forums.

If it is stock recovery then I believe if you can get to download mode then you can flash a custom recovery and flash the superSU zip to root the device then factory reset/wipe data, wipe cache and wipe dalvik cache, this will clear the lockscreen but won't erase his pictures, music, etc., it may let him back into his phone, he will just have to be careful because the device will be rooted and he could make things worse if he doesn't know what he's doing. If that works and he gets back in his phone but isn't comfortable with the risk of having a rooted device without understanding its usage then the device can be un rooted by going into the superSU settings and choosing the unroot and uninstall option. He'd still have custom recovery though. You might even be able to just flash the recovery to do the wipes and not have to root, I'm not sure about that though because I've never used recovery without root so I can't speak from personal experience.
I've never owned the i9300 so I'm not sure if you can do that or not safely from the state you are in so you may want to verify in this forum before you try it, but I don't see an issue with you doing it, its commonly used to root the S3 variants and doesn't wipe any important data or factory reset the device

Whew, most of that went right over my head lol. An idiot's guide please? Bearing in mind that my PC can't currently connect to the phone I'm guessing that I need to put the custom recovery file (where to find one?) on an SD card via a PC card reader and try it from there in download mode? I think he'll be delighted just to get his pictures and videos back even if the phone never works again, so it being rooted won't be an issue.

No, to get to download mode you need to have the phone off, then press and hold the volume down+home+power button, when you see the caution screen you press up, if you can get to this mode you may can flash a TWRP recovery through Odin from PC to phone.
But first, before we get to Odin, do you or he know what android version he had before this happened, Kit Kat? Lollipop? I need to see if there are locked bootloaders on your device builds and which ones they are and which are safe to flash TWRP, if the i9300 is like some of the other Samsung devices with certain locked bootloaders that can't be unlocked or downgraded then flashing TWRP could and probably would brick the device. I need some info so I can check for you.

I honestly have no idea which android build it is running on, as I can't get into the settings page or anything else and I very much doubt if my friend knows as he is pretty much clueless on such things, hence the problem. All I know is that its a few years old and when it starts up there is a three.co.uk white screen icon before it gets to the unresponsive lockscreen. I am also almost as clueless with android devices (I'm only a PC guy) - so far my only experience has been to set up kodi with addons for TV viewing which is why I came here to ask you expert guys
Methinks I won't try to get into download mode just yet in case it makes things worse
All your help is much appreciated, thank you!

The device was never updated, it never had stock upgrades? If not then I can narrow down what was on it, when was the device bought?
If you can boot to download mode and if it is recognized in Odin then you've got a chance, at the moment your PC isn't recognizing the phone but if it successfully connects to Odin then you've got a chance, otherwise I'm not sure what success you'll have.

I would put a spare miniSD card in, flash TWRP recovery in odin, access the storage from there and copy the files to the SD card. Easy as pie.
The international version of the S3 (GT-i9300) already has an unlocked bootloader. So no problem there.
Important to note is that if the device is not rooted the TWRP recovery won't "stick" when the device is allowed to reboot automatically after the odin flash. So in odin you have to UNTICK(!) the reboot option and after flash reboot directly to recovery via holding Vol UP + Home + Power for about 7 sec.

It turns out he bought his partner the same phone around the same time so I checked and it has Automatic upgrades ticked and is on build 4.3 so we can hopefully assume the problematic one is on the same version. When I mentioned the possibility of bricking to him he became unsure as to whether I should proceed with flashing. If he was to send the phone to Samsung themselves would they be able to retrieve his data safely, albeit with some cost and waiting?
Thanks again for your input

I would put a spare miniSD card in, flash TWRP recovery in odin, access the storage from there and copy the files to the SD card. Easy as pie.
The international version of the S3 (GT-i9300) already has an unlocked bootloader. So no problem there.
Important to note is that if the device is not rooted the TWRP recovery won't "stick" when the device is allowed to reboot automatically after the odin flash. So in odin you have to UNTICK(!) the reboot option and after flash reboot directly to recovery via holding Vol UP + Home + Power for about 7 sec.

That sounds good - all he wants is his files back safely. It certainly isn't rooted. So once that is done and I'm back in recovery mode how do I get out of there, just reboot it from there?
Thanks for the help, it is much appreciated

Yes, after you copied the files via the "File Manager" in TWRP you simply choose "reboot system". Rebooting to system will automatically restore the original recovery you are used to. Or you can choose to shutdown in TWRP, remove the SDcard "safely" first and then reboot.
Even more: After you copied all the photos/videos from internal storage (which should be under /storage/sdcard0/DCIM/camera) to SDcard you could simply delete a few of those.
If them taking up too much space is the problem for the lockscreen not working, deleting a few would of course free up some space again, which would then most likely make the lockscreen work again.
But let me make one thing clear: Flashing anything always brings with it the slight(!) possibility something could go wrong, because you are writing to the EMMC of the phone. BUT I can't imagine a samsung staff member doing anything different. He/she would also need to gain access somehow...
After all it's your choice but hundreds of people (including me) have used odin and twrp on different devices for years now without any problem whatsoever. :good:

Ah one more thing. I would definitely make a full backup (System/Data, EFS and bootloader) while I'm at it! You just choose "backup" in twrp, then the "MicroSD card" under "storage" and go from there. Pretty self explanatory. Never hurts to have a backup!

Nice! And were you able to get the lockscreen working again?

Yes indeed, all is working now as it should. The village idiot actually danced off to his car when I returned his phone - he has strict orders from me to move all his stuff to the SD card and make regular backups to his PC!
Thanks again - would never have done it without you guys
