Your phone is compatible with the clockwork recovery touch?
Edit
Excuse is the nexus s forum, so it is compatible xD
Make the root of your phone with any application in the market and install the recovery ClockworkMod touch with Rom manager premium or Rom toolbox Pro. Restart recovery using Rom manager or Rom toolbox and do a full cleaning on the phone. Wipe only data and cache.
Now, select from mount and storage mount USB storage and copy over to your i9020 storage any rom ( try using the cm9 ). If the installation is successful restart, if not try some other roms. More than that I do not know how to help.
P.s.: In theory it should go smoothly, otherwise I do not assume any liability for further damage to the phone ... Good luck!

[Q] How to hard reset Nexus S

hi all
i am trying to do a factory reset to my nexus S but i faced some problems, the phone cant be reset to factory settings. my phone is on 2.3.4 and is rooted
i had tried the following steps
1) going to Settings>Privacy>Reset phone
after i confirm to wipe everything, the phone rebooted and it will stuck at the "Google" logo (in words) with the fastboot unlock logo at the bottom. i took off the battery to shutdown the phone (anything i press at this moment does not get any response from the phone) and start it up again. once it is started (it get pass the google word logo if i do it this way) all my application and even my themes are still there
2) shutting down the phone. press volume up + power button. choose recovery
same thing happen as above. it cant get pass the google word logo and once i restart the phone by plugging out the batt, it went back to previous state without wiping anything
i search online guide and also youtube video and all of them shows that the recovery will bring you to a android with a exclamation mark (in the triangle) but i cant get to the screen. i had left my phone there for 30 minutes but it is still stuck at the google logo.
Please help

thanks for the feedback. now i am trying to flash it but i faced "adb device not found" error
ok done

Make sure to update it eventually because you could run into issues when flashing stuff if your recovery isn't up to date.
No problem!

[Q] SOLVED Problem flashing CyanogenMod 9.1.0 Stable

I rooted my MT4GS a few months ago but stuck with the stock ROM. I decided I wanted to try out the CyanogenMod 9.1 ICS ROM. I followed the following steps:
1) Installed ROM Manager.
2) ROM Manager indicated a newer version of ClockworkMod Recovery and I installed it (5.0.2.7).
3) Using ROM Manager, did a full backup of the current ROM. All went well.
4) Using ROM Manager, downloaded and installed CyanogenMod 9.1.0 stable-doubleshot. I specified to wipe the data and cache partitions. The installation seemed to go normally.
When the phone rebooted, it was stuck at the logo screen. Had to remove the battery to turn it off. Tried a couple times, still the same.
Since I had the backup, I decided I would use CWM to restore the old ROM.
When I boot into recovery mode, it shows CWM 5.0.2.7, but whatever option I try to choose from the recovery menu, The screen just goes blank with the CWM logo in the middle and nothing else happens. Hitting the power button returns me to the menu, but no option works, even power down or reboot. It just goes back to the CWM logo again and I have to remove the battery to shut it down.
So, I thought I would try using fastboot to flash the ROM again. When I boot the phone into the boot loader and select fastboot, then plug the phone in via USB, nothing happens. Windows does not see the phone and ADB or fastboot don't see it either. It's not a driver issue, as the computer is still setup from when the computer was rooted and I connect the phone all the time with no problems.
When the phone is off and plugged into USB or the charger, I still get the charging light, though it goes off after about 10 seconds, then comes back on and cycles like that.
Is there anything I can try at this point, or is my phone bricked? It seems like I followed all the steps correctly. Is there an update.zip I can put in the root folder and see if it picks it up?
Any help would be appreciated.

Ok, after rebooting Windows, I was able to get the USB connection to the phone to work in fastboot. It seems I missed the step described in this thread:
http://forum.xda-developers.com/showthread.php?t=1508556
which states with S-ON you must flash the boot.img separately. I did that via fastboot and the phone boots into cyanogenmod now.
However, I still seem to have the issue with clockwordmod recovery. As long as I do the recovery functions from rom manager, everything is fine, but when I manually boot into the recovery menu, I get the same behavior of any choice from the menu just blanks the screen except for the CWM logo and nothing happens. I tried reflashing the recovery image using fastboot, but still no go.

This is solved also. Seems on the MT4GS, the trackball is the selection button. The power button appears to only be a back button.
What a thread! Two nicely phrased problem definitions, two well explained solutions, and all from the same guy. Sorry we weren't able to help directly, but you obviously found the answers you needed elsewhere in the forum. And you updated the title as well to show it was solved. Thanks.

[EMERGENCY] Bricked Nexus 5 Cant Boot Into Recovery Mode

Hi there, having just the old casual phone crisis. I was running cyanogenmod 12.1 for awhile and decided to finally upgrade to a nougat 7.1 build.
I tried using this one https://forum.xda-developers.com/google-nexus-5/development/rom-dark-rom-t3492150 using adb sideload as I had tried a earlier one and the gapps messed up so I wasn't able to put twrp back on the phone. The rom said it had installed successfully but I wasn't able to sideload gapps, I kept getting an error status 255. I went ahead and just tried to load the rom without gapps and see if I could install it slowly through APKs. I managed to get past the initial android load and the services started up, and it got in an endless crash loop because the phone service wouldn't start. So I went to try and flash another rom and was going to delete the cache. When I went to delete the cache the phone hung for about an hour so I tried to just reset it into recovery mode again.
Now when I hold the power button and volume down key to into fastboot mode I can. I have access to the initial screen with the four options, but when I try to start recovery mode or start the phone my screen goes black, and it'll flash the dead android symbol with the error saying unable to mount cache, it only flashes it for like half a second then goes black and repeats every 10-15 seconds.
I tried holding power down, doing volume up, and letting go to do a hard factory reset but it does nothing. I also can't seem to access the adb sideloading anymore, I'm very scared that it's hard bricked, is there anything I can do at all to fix this.
Flash a new version of the recovery via fastboot. Then do a full wipe. After that install the ROM only! Reboot recovery (not system but recovery) then reflash the ROM (no wipe) and add everything else. Hope this helps you out.
The phone may not boot the ROM without wiping data if installing a 7.1 ROM over a 5.1.1 ROM.

Need help flashing Katkiss 6.0.1 , Recovery Partition Not Found / Nothings Working

So, I just decided to try and Flash the old TF101 with Katkiss 6.0.1 and Gapps, but I always get stuck on the same problem.
My TF101 is running Android 4.0.3 ICS and USB Debugging is on
I downloaded TWRP app on the transformer, as well as the latest .blob flash file through the app.
Before this, I rooted the tablet using Kingroot.apk, which worked. When I went to flash the tablet with the recovery, the app noted "Recovery Partition not found".
I tried to boot into recovery mode on my own, (Pressing Pwr + Volume down , Then hitting Volume Up), The android screen popped, up and then flashed to a fallen android with a red triangle.... The screen stays on this for a minute and then boots into the normal system. I can't even boot into recovery through ADB, using the
Code:
adb reboot recovery
, The tablet will just reboot normally, not into recovery mode.
The Device does recognize through ADB....
Is my recovery partition just non existent? Even when I just let the system though without pressing volume up, it only gives me the option of (Android) or (Erase Data). when I click erase data, ill stay on the asus loading screen indefinitely and nothing will happen until i turn it off and on.
I just cant seem to boot into TWRP for some reason, and that means I just cant install the downloaded custom ROM.
How Can I fix this and boot into TWRP? I've tried for hours and have been hung up due to the same problem each time, even after rooting.
Did you already solve that problem? I also need a solution.Thanks
