Unlocking Vibrant

Hi there,
I am pretty new with this stuff, as I just got this phone today. It came with Froyo2.2 so I unrooted it back to the original JFK.
It did not come with a sim card, so I do not have a sim inside the phone as of now. But I do have a bell sim that I will use after to put the unlock key in... Is that okay?
I Connected the vibrant through Mini Kies and the MTP application says its connected.
I just re rooted from J16 back to the original.
I have the 64 bit drivers installed.
When I try to run Generate Unlock Windows Script I get the following error message saying...
Copy nv_data.bin
*daemon not running. Starting it now *
*daemon started succesfully *
error: device not found
error unable to find file <.\nv_data.bin>
could not find C:\documents and settings\1\desktop\key\generateunlockwindows\nv_data.bin
Anyone know what this means?
Or know what to do in this situation?
I am not sure if I should try installing the 32bit drivers or what.

how did you downgrade the phone from android 2.2?
I just bought the phone through ebay with the OS already at 2.2, and the phone is locked to t-mobile. I've heard it is not possible to unlock it with the 2.2 update. Is that true?

Yup, having exact same problem. If you find a fix let me know.

Make sure your usb setting is on debug and you have all of the files for the unlock on your pc. You also need java installed.
That method worked for me from stock.

can someone answer my question?

I don't know whether the unlock methods work with Froyo but you can download a 2.1 stock Odin in the forum.

Fixing so-called "Bricks"/Odin Errors
This guide is open to contribution/editing/correcting
-----------------------------------------------------------------------------------------------------
BOOT CYCLE
This is where you get the annoying Samsung Screen/Galaxy S screen.
DOWNLOAD REQUIRED (CREDITS TO JUSTANOTHERCROWD):
1. Get into Download Mode (WITH THE PHONE PLUGGED IN) by following the steps below
*Turn off the phone until you get to the charging battery screen (keep in mind, your phone is currently PLUGGED IN)
*Press volume up and down, and power all at once.
*As soon as the screen turns black, release your power button.
2. Unplug phone from USB
3. Open Odin (in Administrator if you're running W7 or Vista), try one of the ones I attached to this post, at least one of them is bound to work, some don't work for me, but works for others, some doesn't work for others, but works for me, whatever floats your boat
4. Load in the files into Odin that you have downloaded from above Just load in the files corresponding to the text field.
DO NOT CHECK REPARTITION.
5. Plug in your phone with the DL mode
6. Click start and wait for the magic
-----------------------------------------------------------------------------------------------------
NO-BOOT PHONES
This is where your phone does NOT turn on, no combo of buttons works and power button does nothing.
DO THIS ONLY WHEN YOU PLUG IN YOUR PHONE AND NOTHING SHOWS UP ON THE SCREEN!!! If else, follow the steps from above.
This method is basically same as above, EXCEPT the way you get into Download Mode as your phone is HARD BROKEN.
1. Download all the files required in the "BOOT CYCLE" section of this post.
2. Remove everything from your phone (SD card, sim, battery).
3. Plug your phone into your computer WITHOUT the battery, as you have already taken it out in the last step.
4. Press and HOLD vol. up and vol. down.
5. As you are HOLDING these buttons, reattach your battery.
6. You should be in Download Mode.
7. Unplug phone from USB
8. Follow steps 4-8 from the "BOOT CYCLE" section.
Troubleshooting:
-Odin stuck at some random process?
*Switch to another odin
*Make sure you did NOT check repartition, if you did, just repeat all the steps over again, except for the downloading parts, obviously.
-Phone not responsive?
*Try "NO-BOOT PHONES"section of this guide
-Phone stuck at Galaxy S logo screen?
*Put it in to DL mode, and run Odin again, it's just a bad install.
-All three ODIN is nonfunctional, stuck or giving "FAILED" errors?
*DO NOT CLOSE ODIN ONCE IT HAS FAILED!
*Unplug your phone
*Replug in your phone, get it into DL mode
* Unplug once it is in DL mode
*Replug and ODIN should recognize your phone
*Leave all the settings the same, then click "Start" again.
-Cannot get into download mode using the method I listed? Use the method(s) below:
Soldering Method
More methods coming soon
-----------------------------------------------------------------------------------------------------
I know how much of a pain posting in the Q/A section can be and the wait time is pretty bad, so if you need help regarding UNBRICKING and ONLY UNBRICKING feel free to post in here.[/S​

If you want help you are going to have to be a lot more specific. What have you actually tried?
Just a tip, people will not help you on these forums if you ask for help without showing you've tried to solve the problem and know how to search.
There are loads of unlock threads. Almost everyone get one method to work eventually.

[Q] Google Rom on S4 boot problem

Hey guys
So I just received my BRAND NEW S4 (i9505), and decided to root/flash it almost out of the box. (Smart, huh?)
I did exactly what CURSED4EVA mention in the 2 videos on youtube about rooting and flashing. The only difference is, when I need to hit REEBOT NOW (after doing the zip, wipes etc), it asks me: "ROM may flash stock recovery on boot. Fix?"
(It doesn't ask HIM that in that video) - Can't link to him, but search: "cursed4eva Galaxy S4 google edition" - and it is the first video about flashing
I tried clicking yes, tried no, tried "avoiding it", tried restore backup and tried all that in both CWM and TWRP.
All in all I end up with the Google colors just looping and looping. Even tried flashing StockDroids Rom, just to see if it was helping.. but no, same problem.
So now I have a brand new phone, DEAD :good:
Any suggestions on what I am doing wrong? It is a i9505 from Denmark.
And and, sorry if this has already been answered. Just coudnt find it anywhere..
Thanks a bunch!

I did the exact same thing and had the same problem! I eventually got it sorted, turned out I forgot to turn on USB Debugging mode before installing CF-Auto-Root. I got stuck at the Nexus loading screen.
I am pretty new to this but thought I would save you the headache, - head over to samersh72's post on unbricking [here], follow the instructions, and you should be just fine, though you'll lose your root and be back at your original stock firmware!
If you need any more help feel free to reply

Dude, thanks man. Will have a look tonight. So basically follow the guide to get back to stock. And after, Awhen Cf auto rooting this time remember to turn on USB debugging mode, right?
Thanks again

well, went back to stock firmware with a perfectly fine phone.
remembered this time enable the usb debugging mode, but problem is still the same. Still stuck at the nexus boot colors.
When I hit reboot now in cwm, it first asks me:
"rom may flash stock recovery on boot. fix"
Then:
"root access possibly lost"

Does not work tried hoosing "no" to both questions
Even if I choose "go back" it's just going to ask next question.
So do I choose "no" to both AFTER a fresh stock firmware install? Maybe try that?

Note 4 Verizon failing to update to Marshmallow

Hello everyone
Please bear me with me for I am a dinosaur that grew up with Symbian phones, then was forced to use Windows phones and now recently converted to Android, therefore not an expert in this field.
Bought the Note 4 off ebay in UK. Mobile banking app and Android Pay say my phone is rooted however Root Checker says it isn't . I have tried to update to Marshmallow through ODIN but I get the FAIL Auth error every time I try...
In settings the phone shows up as N910F however it is a N910V ... I do need help to figure out the precise model though just to make sure I am installing the correct software.
Also, I am using a Lebara SIM card (partners with Vodafone) here in UK, not sure if that matters.
Would really appreciate if someone would have the patience to guide me how to install Marshmallow on my phone, I just want a clean one and no rooting. Tried different tutorials on the internet but none worked for me or I am surely doing something wrong.
Many thanks in advance!
Andy

Hi Andy I'm also in the UK with note 4. To find out the correct model you need to boot to download mode. Power off the phone, Hold volume down + home + power together. It will boot to download mode and from there it will show you the model.
Post your correct model here and I will post the firmware with the correct steps to flash.

Hi Callum
In download mode it says N910V

Ahh you have the verizon varient.
https://www.sammobile.com/firmwares/download/117781/N910VVRS2CPL1_N910VVZW2CPL1_VZW/
Here is the stock marshmallow firmware for your device.
Download and unzip the firmware. Place it in odin in AP. In odin options enable auto reboot and uncheck repartition. Put phone in download mode, connect to pc and start.

Thanks for the firmware , that worked like a charm. Is it possible to install a non-Verizon version on this phone? One that does not have the Verizon preloaded apps?
Also, do you know anything about the Note 4 getting the Nougat update?

You can only flash firmware for your device which is N910V. Which means unfortunately you can only flash verizon firmware. However you can root your phone and use titanium backup to remove the bloat.
As for the N update I have read and heard rumours that we will get it but I don't have my hopes up. Even though the Note 4 is 2 years old it's still a high end device. It hasn't been officially announced yet. Only been announced for s6/s7 and future releases

1st download the firmware.
Download odin, latest version is fine but I use v3.10.6
On phone settings go to about device, tap build number 7 times until developer options is there, go on developer options and enable USB debugging.
Plug phone to pc to make sure drivers are up to date.
Once firmware is downloaded unzip it.
Power off phone and put into download mode, vol down + home + power.
Open odin and click AP, insert the firmware. Odin options should be, re partition UNCHECKED, auto reboot checked, f reset time checked.
Plug phone into pc, in odin log it will say added with blue box saying com:3 or similar.
Press start and it will flash and reboot. The first boot can loop a few times or hang on the Samsung logo for a little while it's normal.
If it hangs for more than 15 minutes remove the battery for a few minutes then power on again and it will boot.
If you get any errors or are unsure let me know.

first of all, i need your firmware, your root method you tried. If you bootloop your phone you must flash the stock firmware through odin .. and then root with a legit way.

i am little bit confused, help me to help you ! Well , now your phone is bootlooped or no? If it is not , what rom do you have? stock one ?
You can try this method as well, because the method you tried needs to flash a custom rom . i do not like that kind of root method . For me first you flash twrp through odin, flash root, better magisk, and then flash your rom .

alright you are gonna need to flash stock rom from sammobile look the link bellow, but first create an account on sammobile . the process will take like 3 hours . after that you flash the stock rom, and boot your phone normally, enable dev option by tapping 7 times on build number on software information, then go to developer options and enable Usb debugging, get your phone on download mode by turning off your phone and pressing the power button, bixby button, and volume up to flash root . i think you know the process . i will be waiting for you reply.
search for your country and csc first. unless if you already have the firmware on you pc.

Galaxy S8 bricked - Stuck in boot loop after flashing twrp

Hey there everyone,
I wanted to root my s8 (sm-950f) and when I flashed twrp my phone initially got stuck in Samsung logo. After managing to shut it down I tried to go to recovery mode to wipe everything and perform a factory reset but I can not do it. All that happens is I get to s8 screen and it reads in red on top left of the screen "Only official released binaries are allowed to be flashed" and it keeps resetting itself. I can access download mode but that's it, I can't do anything else. Currently downloading a stock firmware to try and flash it but with the free downloads it's taking its time. Any help appreciated, I really want to unbrick my phone
note: It shows FRP and OEM lock to be off in download mode, i dont even know if i'll even be able to flash a new fw. Do I just have a very expensive brick in my hands now?

This must be a international S8... Did you activate oem unlock in developer settings before flashing twrp

I'm not sure if it's international, it's most likely a Turkish version.

On the xda thread for your device there aren't no stock roms uploaded to Android host for fast download so you can flash in Odin and start the process of twrp again or just leave it alone you have a S8 it's good money
