nexus bricked need help plz :( - Nexus S Q&A, Help & Troubleshooting

hello..
so i bought a nexus s i9020t from a guy for cheap price...he told me he was updating to ics and someting went wrong and now his device wont boot up...
i can enter fastboot mode with vol+ and power button...but when i try to unlock bootloader it says failed(ive done this many times and with proper drivers and method)..and i cant flash any custom recovery or stock rom from fastboot(also im guessing usb debugging was off).. i also tried adamoutlers resurrection tool...
but it says
sbl injection failure
failed to find device
and that fails to put my fone into download mode..
im stuck and cant run my fone...any kind of help is appreciated..

as you were writing me by pm, i answering here....
#
unfortunatelly, i don't know how to fix it.
i am not familiar with adam outler's resurection tool, maybe a usb jig is working in another way, to bring you into dl mode

Doh. Seems you PMed all RDs around?
How about not unlocking it and just flashing stock Google ROM?

update: when i hold both volume buttons and insert the usb cable..odin recognises the device but the device does not show download mode...instead it shows unlock bootloader screen with no, yes or no options..and when when i flash a package with odin it also says failed...
and rebellos-- "how about not unlocking it and flashing stock google rom"......can u give me pointers how to do that..though i think i know..but nothing is leading me to anything fruitful
plz help me get my fone back..

need help..still in the same position...

i may have bricked my phone please help

i cant believe i did this but i have a sprint tp2 and i accidentally install the wrong rom, i installed 1.8b_Sense_2.5_2012_Full, and after the update the phone wont turn on so i cant even do the bootloader. and hard reset either, nothing is responding. is there any way i can get out of this with a working phone?? would the people at sprint be able to help? and please no smart ass comments im really bummed out about this right now
It should be ok if you only install a gsm rom. If you installed a gsm unlocker than it is bricked. Just push the bootloader buttons with the phone off. If it doesn't go to bootloader it is bricked.
i installed the rom but i think the damn thing CAME with the radio unlocker inside the rom. i cant get into bootloader...
please help
If you can't get into bootloader and it wont turn on it is bricked.
Not to hijack the thread, but on the subject of bricking the phone...
I tried to install Hard SPL using SSPL Manual (downloaded from a link on ppcgeeks.com). I ran it from the phone, and the screen blanked as normal, but no USB device was detected after doing so and the manual Hard SPL would not work either.
I tried to reset and remove the battery. The phone will not turn on, will not enter boot loader mode, nothing! EXCEPT for one thing, when I plug in USB now, it is detected as a Qualcomm CDMA Technologies MSM. No driver though (Win 7 or Win XP).
Is there any way to recover from this?

Hi, I have the exact same issue as the member above. I tryed to go to the ftp site you reccomended, but can't download. Can you please help! I cant sleep or think of anything else. Can't believe I did that to my phone.
go here and then to touch pro 2 stock roms. ftp://up.ppcgeeks.com/
Thanks for the replies.
I can't load the stock ROM since the phone is not recognized by ActiveSync. While you can see it when you connect USB, it isn't actually usuable as there is no driver loaded for it. And many drivers I've tried for it do not work either.
I did try [to install the ROM] though just to make sure there was no magic going on behind the scenes, but no go.
EDIT: Grammer fix

First and foremost, this belongs in the q&a section. Is your phone an MB865, an ME865, is it AT&T branded? Have you tried uninstalling then reinstalling the Motorola drivers on your PC? Tried a different USB port and/or another PC? Can you give a little more information? Awesome sound effects, by the way.lol

Yeah, I was kidding. This site can be too serious at times. I know you said you tried everything, but a lot of people say that and it isn't always true, especially when they ask questions on the same day they became a member. I wasn't trying to offend you or insinuate anything. I asked if you had an AT&T branded phone because I was curious as to why you wanted to flash to 2.3.5 then ota to 2.3.6 then ota again to 4.0.4 instead of using this:
http://forum.xda-developers.com/showthread.php?t=1961310
to go straight to 4.0.4?
So your PC isn't detecting your phone, but ONLY when in fastboot mode, correct? Is the phone detecting the PC? By that I mean, on my phone when I boot into fastboot mode, at first it says:
AP Fastboot Flash Mode (S)
0A.72
Battery OK
OK to Program
Connect USB
Data Cable
Then when I connect it to the PC it changes to:
AP Fastboot Flash Mode (S)
0A.72
Battery OK
OK to Program
Transfer Mode:
USB Connected
Are you at least getting that?

wot motorola driver ..?? i have installed moto device manager and it is not showing any thing connected.. because it remain in boot mode..:crying::crying::crying::crying::crying::crying::crying:
Use Virtual PC
I still have the same issue. I have installed Windows 7 on VM Ware workstation i.e virtual desktop and then followed the below steps :-
-Reboot your Virtual PC
-Install Motorola drivers.
-Reboot your computer
-Install RSD Lite
-Reboot your computer
-Boot your phone into Fastboot mode
-Connect your phone to your computer using a high-quality (preferably OEM) cable.
-Let your PC install any necessary drivers. When it finishes it should tell you that the device "Fastboot Edison S" is ready for use.
-Turn your phone off, disconnect the cable
-Reboot your computer
-Boot your phone back into Fastboot mode
-Wait a couple seconds then connect your phone to your computer
-Wait a couple more seconds, then look at the bottom text that's displayed on your phone. It should say
This means that your phone is connected to your computer.
-Open up RSD Lite
-Wait a couple seconds. At the top of the list should be your phone (under model it should say "Fastboot Edison S")
-If you've done all this and everything has worked out for you, flash the fxz! Make sure to follow the instructions in the noob thread as specifically as possible

This seems to be happening more lately. it IS a driver issue of some sort, that is for sure. I would just use one of the scripts, or moto-fastboot manually. they do the same thing as rsd but through command line either with your own typing, or a .bat script.
This may also work better in linux, so you can try downloading a live cd/usb of ubuntu and seeing if it is recognized. no need for drives with linux, just download one of the scripts that includes the moto-fastboot utility. Let me know if you need more help.

Read some Stickies, there's guides written to fix this. It's in Android development, called softbrick repair guide.
If you're still confused do a search, this question was answered 1000 times. It's an easy fix.

Your device has a locked bootloader, you can't flash TWRP on a device with a locked bootloader. Don't just assume you can flash anything on any device, there are factors that change what can be flashed or even if anything can be flashed at all.
Your only options are:
1) flash stock firmware via Odin
2) follow this thread to unbrick Verizon S3
https://forum.xda-developers.com/showthread.php?t=2581166
3) send your device to a repair shop that offers a JTAG service.
4) replace the motherboard in your device
5) buy a new device.

It's just softbricked, you don't need to use JTAG or the hard brick guide, just follow the softbricked guide with a ne1 stock ROM. The one by the pagel works perfectly.

The boot from SD card method that I gave you a link to might work in your situation.
Or, you can try buying a USB jig from eBay for $3-5, it's a tool designed to force your device into download mode. It isn't guaranteed to work but if it does you can flash the firmware. If it doesn't then you only lose $5.
If you can't fix it yourself then a JTAG service is your best option, it isn't guaranteed to work either and it usually costs around $50 plus it has to be shipped to the shop, repaired and then shipped back to you.
Or you can buy another motherboard and put the new one in your device. This is an option you can do yourself of you're careful.

There's no reason why you can't get into download mode.
USB jig, or use ADB and force it into download mode.
There is absolutely no way you're hard bricked, booting from an SD card won't work in this case because your phone turns on normally. Just keep trying every method you can find to force your phone into download mode and work from there.

Have you tried pulling the battery out, then holding the volume down+home+power then inserting the battery to "bump" it into download mode?
It's a little tricky but has been known to work pretty reliably.

Samsung Galaxy S8+ Hard Bricked. Only Upload Mode!! How to Enter Download Mode???

Ok so I went to flash twrp recovery onto my phone and something went wrong while using oden... My usb debugging is turned on and OEM Unlocked. Now my phone screen stays completely black. Its caught in a bootloop and No buttons work to bring it back into download mode, Only Upload mode works.. But Odin will not flash anything to my phone in Upload mode. It changes my samsung usb drivers to msm upload or modem drivers. I have been at this for weeks trying to get my s8+ to attach to my computer again using ADB, ODIN, SD CARD, AND EVEN THAT JIG Thing to force it into download mode but TO NO AVAIL.. I Have to some how get back into download mode but no button combinations will work.. It seems to bootloop on me before it reaches those commands. The bootloader is obviously gone to a certain degree since upload mode still works.. Is there any way to use Odin in upload mode? Or is there any other way I can reflash stock rom to fix this issue? I have no recovery, no safe mode, no download mode?? My phone is basically a paper weight right now.. When I know All my stuff is still on there. This S8+ Phone has put up a good fight with me on my pc But Im not one to loose. I love a good challange.. Any suggestions. I thought ADB Was my best bet but with no connect I cant do any thing. I cant' get Adb to find my device. Oh even tryed older versions of odin with low level quallcom drivers and that didn't work either. Odin will read a com port to my device but i'm in the wrong mode (Upload Mode) and Odin cant establish a connection. When in Upload Mode its the hellish one as xda deveopers have said before..
S8+ phone is Model Number SM-G950U
Witch I believe has now been upgraded to SM-G955U OR F.. But I have the original stock rom still for SM-G950U if only I can get into some kind of Download Mode.
Ive even sat watching odin as I push every single button combination watching the ports appear and dissapear as it reboots trying to find some kind of way to download to the phone... But no luck..

Witch I believe has now been upgraded to SM-G955U OR F.. But I have the original stock rom still for SM-G950U if only I can get into some kind of Download Mode.
Ive even sat watching odin as I push every single button combination watching the ports appear and dissapear as it reboots trying to find some kind of way to download to the phone... But no luck..

Then if I hold the up button for a few seconds I get this underneath

Not sure what that means or how to look up those codes but I know its all bad.. If anyone can think of any other way to connect my phone to reflash stock rom to fix Please let me know any theories or suggestions you may have for me to try... Thank You...

You have a 950 u locked bootloader. First mistake trying to flash twrp. Only option you have is finding the revision bootloader you where on edl files and pinout to 9008 edl mode. There as of last known no fix other than for upload mode only.
Thank You

It was on its original bootloader for the Samsung Galaxy S8+ SM-G950U. It was SnapDragon bootloader

Mate there are 7 different revisions of the 950 u bootloader. Across all the software updates. No offense intended. But if you can't even give this little bit of info I can assure you. Your not gonna be able to dissemble this device. Ground out the test points to enter edl. And flash needed repair files. Which is very tedious. If there is any issues. I would mark this device as lost and get another. I dont feel that you have the necessary skills needed to complete this process...

You are not in edl mode. You are stuck in upload. The only way to get to edl mode is disassemble the device flip the motherboard upside down while hooked up. Ground out a test pin on the mother board while connecting the usb cable.

Fastboot, Samsung Galaxy A51

Hello, i wanted to ask how to fix the fastboot mode.
Everytime when i try to access it, it just says "Entering Fastboot..."and thats all.
I dont want to close it, thats not my problem, i just wanna flash a recovery.img, and the fastboot seems not working. Any ideas?

this could be because the galaxy A51 wasnt built with fastboot, and the code to launch this option was just reused from a different device, or because something isnt connecting properly.
Hello, I have the same ... Android 11 (and currently 12) (from Frija). So it is not the fault of incorrect configuration or with connecting. Only something is wrong with this phone ...
I have this device and this solved it for me:
Enable OEM unlocking in developer settings
Shut down the phone
Hold volume up and volume down
Plug in a USB cable connected to a computer (the computer being turned on)
Keep holding
You're in download mode!
Side note: This might not work in USA or Canada, I am from europe and it works here. I have no idea if it works in another region. Also, you can't just flash a recovery.img on Samsung since there is no real "fastboot", you have to use download mode and Odin.
But I know how to enter download mode... Problem is Fastboot mode...
There is no fastboot mode on a modern Samsung device. If there is, it's fake and you cannot flash anything with it. As you can see even from Wikipedia, Odin is the Samsung replacement of fastboot.
So no fastboot, only download mode.
If a guide is saying to use fastboot, it is not compatible with Samsung.
If you would tell me why you specifically need fastboot, I'll be happy to tell you how you can do it with Odin, if possible.
Because I have Samsung Galaxy A51 5G (A516B) with new Android 12 and I can't do a root! Because I can't upload TWRP (custom recovery) because I haven't OEM unlock option in Deveoper Option. I tried trick with set back date by 7days but not succes. Everything I;ve metioned here - I did at my phone with Android 11.
And... I have read that I can turn this fu**ing OEM option by comend at ADB: fastboot oem unlock.
Phew ...
So this fastboot method is the last method to do a root with my phone.
Upload TWRP by Odin in download mode -ends red warning - of corse...
Have you any ideas?
I would be grateful for help...
I have read this fastboot method at:
How to Unlock Bootloader On Samsung Galaxy Phones [EASY GUIDE]
Are you looking for a Complete tutorial on How To Unlock Bootloader on Samsung Galaxy Phones? If yes, then you have come to the right place.
www.guidetoroot.com
Yeah, that guide is not relevant on any modern Samsung device. Besides, even if it was, which it isn't, you would first need to enable OEM unlocking from the Developer Settings.
But the fact that you don't have an option for OEM unlock is weird, since I have the exact same device model and it is there for me.
May I ask what is your region and is your phone locked to a telephone carrier?
My region is PLS - Poland. And not - phone is not locked. Have you the newest system Android 12?
Yes, I do. It's weird that there isn't even an option for you.
I'll try to come up with some new ideas if I have time...
I'll be glad for it...
Hej, do you have any idea?

Yes, I did. Evething exept the last one...
You could try it. It might be risky, but it's the only option I personally can come up with right now.
I've tried this option but Odin stuck on "files verification". Any help?
have any of you encountered this problem?
And how did you solve it?
You can also try searching for combination firmware for your device online
