Please help with fixing root mishap: Wind Nexus S

Hi, I've been following countless guides on how to root the Nexus S, and I've used countless different root and recovery .img files and none have worked. When I boot the phone, I'm stuck at the Google logo screen and it won't go anywhere from there.
My phone is Wind's Nexus S, GT-i9020... under the battery it says model:GT-9020T

Flash the latest clockwork 3 recovery img and then hold down the volume up and power to get into recovery.
Flash a cyanogen rom or something.
You may need to mount storage through USB in clockwork to copy rom's to it.

Make sure you flash a compatible boot image file. I, too, was stuck on the boot screen until I flashed the right boot image file. Some people swear that the data cable that comes in the box is junk and leads to headaches when trying to root. I have not experienced that, but it's worth a try. Uninstall any Android drivers on your system, and ONLY install the Google provided drivers. That's all I can think of right now, when I was trying to root my phone. I hope this helps.

I needed the Google USB drivers from the SDK and the PDAnet drivers. This was on a Windows 7 laptop.
Its not hard to find the right clockwork 3 img file. I did have to rename the img file from clockworkrecovery3blahblah.img to recovery.img
Once that is done flashing, boot into clockwork recovery and choose to mount the USB storage. Copy a cyanogen rom to the phone then choose to install zip from sdcard in clockwork.

Thanks for the responses. It seems I should not have flashed the boot.img at all. I was able to reset the phone to stock using the zip from this post[/quote], and from there did a correct root using 4002-orange.img for recovery and su-2.3.6.1-ef-signed.zip. There are a lot of bad guides on rooting out there, it took hours of searching and some second luck on stumbling across the right post to reset the phone to factory.

I'm guessing you flashed a boot.img to try and root it?
That's what screwed up.
Take battery out, put it back in, hold volume up and power at the same time to get to Bootloader.
Flash the latest cwm recovery, boot to recovery. mount the internal usb,

Revert back to stock a500?

I have a a500 running an ICS rom. I want to revert back to stock and not have root access anymore. How can I go about doing this. If anyone can help please let me know.

GOOGLE STOCK UPDATE.ZIP ROM for acer iconia a500
ethere are two types of these around.. ONE WILL FLASH WITH CWM. The other must be flashed with the stock recovery.
cwm well your on custom rom so you know how to do this..
stock recovery. YOU CAN USE acer recovery installer to install the STOCK RECOVERY BACK onto your tablet. (read about boot -loader version you have )there could be a issue if you have the patched boot ics loader.
once you are back to stcok recovery put the stock update .zip on root of sd card( not in a folder) power off device .. Hold vol up button down. and power button it will boot into recovery and start flashing..
There are several threads explaining all of this in great detail. even some with d/load links to the rom files..
GOOGLE IS YOUR FRIEND. THE ABOVE IS REFERENCE ONLY AND THERE Could be easier ways.
GOOD LUCK.

I have timmydeans original zip, which will flash a full stock hc 3.2 Gen 1 rom/recovery
It comes with full instructions and an excellent guide from christos too
You do not need an sdcard for this method altho' u will need working ADB
If u want it let me know and I'll upload it somewhere for you

IF you are on the HC bootloader then you'll be ok on this
Just so you know:
THIS WILL WIPE ALL YOUR DATA, so backup any important files/photos etc...
You need your CPUID if you have a CWM backup then you'll find it in there
Use christos Guide as its a bit more detailed, you'll only need to follow along until step 24 - the rest of the steps entail getting root and installing CWM
Once the flash is done you will see in white letters PASS and underneath that a small red message "Secure boot: image LNX checksum fail!" this is not an error, just keep following the instructions.
If you're on the ICS Bootloader you are still able to use this, but the method is a lot different to the one above - let me know if you need the instructions
Acer Recovery Installer will tell you what version bootloader you have

hi darvis, sorry, thought you were OP - you're not still trying to unbrick are you???

You can download the stock ROM from the developer’s thread here.http://forum.xda-developers.com/showthread.php?t=1422504
To flash the ROM, you can follow these simple steps given below:
Download the ROM from the link posted above and transfer it to your External SD card
Power off your device and boot into recovery mode (Hold Volume Down & Power button together, and release both when you see text at the top of the screen)
Perform a full backup of your existing ROM as a precautionary measure
Perform a full wipe (Wipe Data, Wipe Cache partition & Wipe Dalvik Cache in Advanced Options)
Install zip from SD card/Choose zip from SD card ( here, select the zip file you copied to your sd card in Step 1)
Once the installation is complete, reboot.
Thats it!! Your’e done, and should now be running Stock Honeycomb version 3.2.1 with root.

you've been having some troubs titan - are u stuck in apxmode still or what?
if you're on the patched bl can u boot into fastboot (pwr/vol up)?
do u have another pc you can try this on?
try running a500 manager and see if it recognises that yr tab is in apx mode (pwr lite on and black screen) the boot/recovery drivers must load b4 you can get into bootloader download mode/a500 apx mode displayed on yr tab screen - check device manager.....usb controllers...if they are there then uninstall them, reboot tab and pc. Use a different usb port to connect yr cable and fingers crossed the drivers will install and you can carry on from there...what can happen sometimes with a failed nvflash/euu is the drivers get screwed up and MUST be reinstalled again before any flash will take place
One other thing...don't panic....i've struck this a couple of times where nothing seems to work, even my old faithfull timmydeans v4 sometimes fails to get me out of apx mode, but uninstalling all acer and google drivers, disconnect the cable and clean boot seems to work...in the end!!! oh another tip don't have your tab connected to the pc while booting up - clean boot all round, then connect yr cable and wait for the drivers to install.
once you're up n running again, full wipe and fully format EVERYTHING do it 3 times at least and even after youve flashed yr rom on there, fastboot is the easiest way to do this and also the most riskiest if you accidentally give it the wrong command so be meticulous here - if u brick it with fastboot - well, i don't know if theres any way back after that
the instructions i spoke of earlier are all in jazzyjames rollback thread

Cool, so if you install adb onto your PC and set it up you can sideload a ROM to your recovery....and if you want you can flash stock in download mode with thread in general forum....I'm hitting the sack but if you look up adb sideload you should be able to get all the instructions
---------- Post added at 01:48 AM ---------- Previous post was at 01:46 AM ----------
Basically once you have adb setup and have a ROM ready its a piece of cake and lots of threads if you Google it

I think I will have a problem with ADB, because before flashing I disable the USB debugging mode !!!! and unfortunatly I can't enable it !! Am I true ???

Sent from my LG-D801 using Tapatalk

look into your recovery settings, it should have an adb option you can togle, otherwise let it go in booting loop.
navigate to the folder with the files you rooted with. There should be a adb file.
then shift rightclick if windows on that folder that contains that stuff. Select command prompt from here.
adb devices,
or adb it will or should list the phone, then find the codes to push the desired rom and optional apps to root\sdcard.
then adb reboot recovery, or reboot manually into recovery and flash your rom plus optional gapps

adb didn't work, can't recognize my device with qdb devices command !!
anyway, I flash the stock rom in Download mode and then root, TWRP and custom Rom and everything is good now !!

Failed to root phone correctly and accidentally wiped everything. Please help!

I tried to root my phone using Moto G5 Plus toolkit. I failed to root it properly and I forgot to back up my system before attempting to root it. I failed to root it properly and Instead of having Motorola on my phone I have Team Win Recovery Project. I also keep getting a messages saying " Your device has been unlocked and can't be trusted ID:N/A will boot in 5 seconds." I don't know what to do. I believe I have wiped my whole phone. Is there a way to repair it? Can I fix it by reinstalling the factory stock firmware and drivers. I am try to solve this problem and fix the phone. My phone is a XT1687 Moto G5 Plus. I do not know where to get the stock or factory default software for the phone or how to reinstall it. Nor do I know how to remove the Team win Recovery project from my phone. Can someone help me. If you are able to can you tell me how to fix my phone.

You did it right you installed the twrp( team win recovery project) recovery. now download a rom on your memory card , wipe all data through recovery and install the rom through recovery.

Twrp is a custom recovery for custom roms. Removing it is not so easy process. Twrp recovery is better than stock recovery.
Now in twrp wipe your internal storage cache and data, don't wipe your external sd card. After wiping go to install in twrp select the rom you downloaded and then flash it.

I'm not sure if I am able to flash a boot logo. I can't turn on or off the OEM Unlocking option in the developers settings. Without OEM Unlocking I can't unlock the boot loader.
The OEM Unlocking option is completely grayed out. It appears to be locked. I can't tell if it is on or off. It might be locked in on mode.

I think your bootloader is unlocked. Reboot to bootloader it will show if your bootloader is locked or not. If it is not then flash the bootlogo
