Hi,
my friend's Nexus S was stuck in a bootloop. i went into recovery mode and hard reset the phone, so that the phone would come back to stock. however, the phone was being reset when the battery of the phone came off, switching it off.
the phone fails to start. there is no response when i try charging it. Also, it does not go into DOWNLOAD mode or FASTBOOT, so i cant even run any utilities to flash the stock rom back. adb commands as well as the nexus toolkit show that there is no device connected.
can anybody suggest me what to do?? i was gonna try odin but i read somewhere that it is only useful for custom recoveries, not to flash stock roms.
i've gotten some usb drivers mentioned at some thread, saying i would have to update my 'android' device listed in the device manager using them, but i cant seem to find any device mentioned in my device manager either.
any suggestions as to what i should do??

Something like this happened to me a week ago. I have Nexus S 4G. So, I ordered USB Jig from usbjig.com and now I have download mode. It worked! :laugh:
You can buy USB Jig from that site, or build it yourself, or borrow it from someone.

Hello, I recently decided to root my phone and place Cyanogenmod on it. When I did that I realized my radio was no longer working. In an attempt to just get back to a working phone for the time being I flashed a rom that I believe was just for the Nexus S and not Nexus S 4G. Due to my stupidity I am unable to communicate from the device to my computer using USB. When I attach the device to the computer nothing happens. The device does not even appear in the device manager. I have tried on multiple computers as well. On top of that the rom seems to have put me back into the stock recovery. If anyone could help me figure out just how to get USB working again I would be very appreciative.
I should note that I can still transfer files to the phone using the sd card or via ftp.
Thank you for your time and help.
Change the USB cable?
Yes, forgot to mention that. I have tried 2 cables both of which work on other devices.
What if you hold in the middle of the volume buttons (i.e. both up and down at the same time) and keep holding, then plug in to your usb port? It should come up as download mode. If it will do that you might try using Odin.
Or try a different machine perhaps?
are the drivers the same for the S as the 4g?
do you have clockwork on the phone or have you tried to run recover by holding volume up and power?
just throwing things out.
Hello, I appreciate any and all suggestions and help.
I have Odin downloaded and installed, but the computer can not find the device so Odin can not do what it needs to do. This is even the case in download mode.
In terms of recovery I am on the stock recovery. I was on clockwork but made a small mistake and now am back to stock.
I know if I can just get the computer to see the phone exists I can fix it.
If you can find the full OTA package for NS4G, you can try putting it on the SD card and flash it via stock recovery.
Also another thing worth trying is connecting the phone to an Ubuntu machine and see if it's detected or not.
I have tried looking for the original full OS. I will continue looking, but the different OS thing is a good idea I did not think of. I will attempt that now. Thank you.
I installed Ubuntu and the Android SDK and Ubuntu was unable to see the phone as well. I am going to keep searching for the original firmware to see if that will fix it. Thank you for your help so far, it is greatly appreciated.
I have found the only rom my phone will accept now is
Android 2.3.4/GRJ22/KRKC1 Radio/KA3 Bootloader
Which is for the M200 variant. This apparently the Korean version.
hello,
I hope someone can help me with my AT&T LG Optimus Pro G phone, which I have royally screwed up.
I was experimenting with the cyogen mod and after installation I installed the freegee app and once the cwm recovery was installed, I decided to go into the recovery by holding down up volume and power button.
Once I was in recovery for CWM i couldn't exit out, and the phone constantly booted into recovery after every reboot, even if i took out the battery, and powered it on.
I tried reflashing the cynogen mod through the sd card, and even though I would get success message the phone would still reboot into the cwm recovery.
I started doing research on the internet and i found file exitrecovery.zip that could be used to possibly get the phone out of the cwm recovery.
After installing exitrecovery.zip, I rebooted the phone, and now I have complete black screen. There are no light, no hints the phone is even turning on, and I can't get into recovery( or at least I can't tell). The only thing now is that when i connect the phone to the computer the window tries to install drivers for the device, and eventually prompts to insert a CD for LG drivers. I already have LGUnitedMobileDriver v.3.10.1 connection drivers installed from their website.
Please help, I am really stuck here..... and have no clue what to do. I am fairly new with rooting and modding, and I am extremely miserable.
The phone is still under warranty from LG. Anyone if all else fails, and since the phone has no screen or lights, whether they would replace it?
Attaching the exitrecovery.zip that I used.
sobbing....

hi, thanks for your reply. Again I very much new to the rooting and android OS tinkering, and nowhere close to an experienced user.
I tried to use google with your information in regards to how to use flow ROM with expansion.exe, but did not get any leads.
I would appreciate if you could elaborate more on this process.
When my phone is connect to the computer via usb is is constantly trying to install drivers. I had already installed LG usb connection drivers in the past and it was successful. It almost seems it tries to install driver yet fails after receiving no input from the phone, and then request LG CD with drivers.

Try to find driver on the web-site of producer. Set them. Overload a vehicle in Bootloader. In the controller of devices on компе must be determined your device. Then on a computer start sewing - .EXE.
Did you get this problem resolved? I have the exact problem with the exact phone!!!
thank you very much
So today, I tried to install TWRP onto a standard, 4.0.4 Samsung Stellar. Followed the instructions, went through Odin, and it failed with auth errors. Well, crap. Reboot the phone, get into there, and try to use GooManager to do it for me. I let it do the standard OpenBootloader or whatever, didn't work. So then I tried EZ-Unlocker. Unlocked just fine, until I turned off the phone. Try booting it, nothing happens; no vibration, no sound, no screen, nothing. I thought this was a dead battery (The battery was running at literally, 3% after I used EZ-Unlocker), so I plugged it in. No red light. Take out the battery, slap it back in. Same result, nothing happens to the phone. Well, crap. Try holding the power button again, nothing happens. Connect it to my computer and it reads it as some QUSB or whatever; look that up, download and installed a driver file for Qualcomm, and now Odin3Execution recognizes it, but Odin 3.07 doesn't. However, I still cannot use Odin to try flashing a new ROM onto it or anything because I cannot get into Odin mode. I was thinking of buying a USB jig to get it into Odin, but I want to confirm with someone else that this is a full hard-brick and not me being stupid.
tl;dr: Stellar doesn't boot at all; power button unresponsive, cannot get into recovery or download/odin mode; computer recognized it as QHSUSB_DLOAD, installed drivers to get it to be recognized as a Qualcomm HS-USB QDLoader 9008 at COM7. Very similar to http://forum.xda-developers.com/showthread.php?t=822939 but just a different phone.
edit: I found this: http://rootzwiki.com/topic/109153-howto-unbrick-a-bootloader-bricked-stellar/ but the download link times out. I'm willing to try this since it may solve the problem. Does anyone know where I can find a mirror of the download link?
edit2: I just sent a PM to invisiblek here on XDA.
edit3: And thanks to invisiblek, I managed to get it into download mode! Solved; if you want the stella-unbrick file, shoot me a PM and I'll upload it somewhere.
I an also looking for solution and need your help.
Sent from my SCH-R830 using XDA Free mobile app

hello
could you give the download link where I can find bricked soln. as such I bricked my stellar and I want to use it in India so I want to unlock it too.
Kindly help and hope to get back from you soon
i made a extremely poor decision and was trying to change the boot animation loader when i actually changed the boot cmd and now it boots to samsung then to download everytime,. i can get into the onboard recovery yet i cant access safestrap and none of the many many drivers ive tried i cant get the phone to show to connect, its listed as unknown device in my device manager and ive hand picked the ones im supposed to have to other ones. ADB doesnt see it either and i was wondering if there is cmd for adb to find myu device, if you help me guys i promise ill only practice on hand me down smart phones. Ty:cyclops: [email protected] SM-G870A
This may be a dumb question, but have you tried Odin? I have had situations similar to this with my Samsung devices and always thought i bricked. But as long i could get into download mode, i could Odin back to stock and start over.

ya but i havent even tried loading a file into odin cause it wont see my device
and i have installed the samsung drivers but after this happened my pc wont see the phone
has to be a way to get a connection between the pc and phone
I'm not an expert so I'm not sure. Do you have the correct drivers installed on PC?
---------- Post added at 06:34 AM ---------- Previous post was at 06:30 AM ----------
Try different Odin versions. And make sure you have the proper drivers installed on the PC.
ya ive actually read that it probably doesnt have the function running to talk with the pc cause it cant boot. im all set up to reset the phoone. just need it to appear in my odin

When you boot to system
It doesn't show anything right ??
but the touch is still functioning
Sent from my GT-i9300 running cm11 using tapatalk.
when i just boot it goes to download mode and says "could not do do normal boot"
i can access recovery mode and download mode but i cant get drivers to show it, and it used to show it until i did this, can i put a file on my micro SDcard from my pc via card reader then install it in recovery mode ? like firmware or a memory wipe reset?
If you can get into recovery, I believe that would be possible. Couldn't hurt to try. As long as you can get into recovery and all the recovery functions work, I don't see why you couldn't.
fixed it!
well after two nights of reading i got my pc to discover the device by changing ports three different times to find one that seamed to like it. and also installed kies and installed the drivers from them, (figured couldnt go wrong after as many as ive used from samsung and others). so win7 pro / altered boot command and only stock options afterwards sucks big time. ty all for helping me
never let up
Edit: It seemed as it solved itself, look in the replies for details
So i have had my gs7 rooted for a year or longer. Yesterday i rebooted my phone and got the error message "Custom binary blocked by FRP lock". Sadly, when i enter download mode and plug it into a pc with odin installed, it is not recognised. Odin does not say anything about a phone plugged in, and windows says the usb is not recognized.
What i think have caused this:
I downloaded an app that allowed me to record internal audio
I turned off developer options, and my stupid ass did not realize that is where oem unlock is located.
What i have tried:
Resetting to factory settings (from recovery mode)
Deleting cache (from recovery mode)
Using odin, but odin does not even recognize my phone
Tried using another computer with odin
tbh, looking at the other posts, i think i messed up. I dont want to send it in for repairing because i will have to pay a lot of money. I have tried sending it in for repairing a while ago. Then my problem was that i could not call with it, but they wanted me to pay the price for a new phone to repair my old phone, since i had rooted it. I did not accept it so i got my phone back, and managed to fix the issue myself. I hope i manage to fix the issue this time aswell.

I have samsung usb drivers installed, and download mode has always been working and has always been recognized by odin ever since this happened. And online all i find is that i should boot into download mode and try using odin, but odin does not recognize my phone, nor does my computer.

Please pay attention to guides when messing about with your phone, OEM and Debugg are critical to being able to modify.

SOLVED!
The issue fixed itself, im not sure what i did. I was suddenly able to connect my phone to odin. Just incase someone reads this with the same problem. This is what i did: installed smart switch and rebooted my computer. Uninstalled and reinstalled samsung usb drivers.
Before i did those things the issue was still there, i was ready to use smart switch, but i tried odin one last time and it worked. Now samsung pass tells me my phone is rooted, even though it is not (my root dissapeared after resetting my phone), its not that big of an issue, just thought id let you know
