First you need : http://www.4shared.com/zip/2L09-JyW/Root_Nexus_S.html
After that you need : remove install-recovery.sh just in .....
run in windows-> Start->at the search bar write cmd and navigate into your android sdk is installed
For me :
C:/"Programs and Files (x86)"/Android/android-sdk/tools/>adb shell
# rm /system/etc/install-recovery.sh
#exit
or with Root Explorer into system/etc/install-recovery.sh just renam it (ex. : .sh.old)
Now you can download this Stock Romv2.3.4 : http://www.4shared.com/file/cJbNf1Nf/NexusS.html
just unpack Nexus.7z with passw: surdupetru
Now , copy NexusS.zip into sdcard, and than you can install it with CWM
( shut down your phone -> press power and volume up at the same time -> choose recovery mod-> wipe data/factory reset, wipe cache partition , advanced Wipe Dalvick-Cache and now choose install zip from sdcard, yes -> navigate into your sdcard and click NexusS.zip. Waitt for installing ...and you will see a nice Stock Android 2.3.4 with root permission, fast & more stable! Good luck!

plz heeeeeeeeelp meeeeeeeeee!

Installing 3.1 OTA update with custom recovery

Ran into this issue as I'm running a custom recovery and couldn't flash the update. Took the time to figure out how to do this properly as I couldn't find any existing set of instructions and I'm sure some people will want them.
WARNING: Flashing this update WILL reset root and the recovery partition. These steps restore both. Restoring custom recovery will require a PC with ADB installed as I was only able to find the raw .img file and not a flashable .zip.
1). Download full update zip by navigating to Settings > About tablet > System updates > Check full update (http://i.imgur.com/ozGBzKZ.png)
2). After update is finished downloading, navigate to /data/data/com.nvidia.ota/files/ROM (I used Root Explorer) and move the downloaded update to either your internal or external storage card. DO NOT TAP THE NOTIFICATION THAT SAYS TAP HERE TO INSTALL UPDATE!
3). Download flashable SuperSU.zip from http://download.chainfire.eu/supersu
4). Download CWM recovery.img from http://forum.xda-developers.com/shi.../recovery-cwm-recovery-nvidia-shield-t2848064
5). Reboot recovery
6). Make a nandroid backup in recovery first before doing anything
7). Flash full update archive (DO NOT REBOOT AFTERWARDS)
8). Flash SuperSU archive (this will restore root)
9). Follow instructions at http://forum.xda-developers.com/shield-tablet/development/root-root-lollipop-t2945044 to use dd to restore custom recovery through adb shell.
10). Wipe cache/dalvik
11). Reboot!
In the off chance that you screw something up and need to force your tablet back into recovery mode manually, the button combo is Power + Volume Down. Also, I was able to dirty flash (not wipe data first) and everything seems to be working fine. As far as the update goes, audio/wifi is working without issue and if anything, the tablet seems more responsive (doesn't slow down/lock up as much). I literally pounded out these instructions after getting my tablet updated so I haven't had a chance to mess around with it much yet.

OTA update bootloop fix [S-ON] [BU] [Stock Rooted ROM]

Hi, I found a way to fix this bootloop which happens after you flash the latest ota update if you have unlocked and rooted your stock rom.
I own a HTC E8 China Unicom [M8Sw - dual sim], but I think it will work on other variants.
It is the SU binary/files which are preventing the phone from updating correctly.
You can also restore a clean unrooted TWRP backup and do the OTA update.. it will work just fine.
This tutorial is for those who don't want to lose their app data and modifications.
To be able to update... you need to fully unroot the phone before. Well, this was previously not possible due to system write protection.
(There are also other methods of unrooting. (deleting the SU files manually with the file manager of TWRP recovery) This doesn't work, I have tried it myself..often cause bootloops.)
But now we have a custom recovery mod which enables us to write to the system partition and thus can fully unroot with SuperSU app itself.
Requirements:
-some expertise with adb/flashing/twrp recovery management will be needed.
-stock firmware.zip, inside the OTA zip file, where you will find you stock recovery,boot image, etc
-Stock ROM, rooted with no modified existing system files
-TWRP Recovery from @Captain_Throwback works fine. I used the 2.8.6.0 one. http://forum.xda-developers.com/one-e8/orig-development/recovery-twrp-touch-recovery-t3060188
-untouched Stock Kernel Modules (IMPORTANT)
-SchKernel Extra 3.3, to gain write permission to /system http://forum.xda-developers.com/one-e8/general/schkernel-extra-3-3-t3200090
[UPDATE: SchKernel Extra has been updated to 3.5 and the old one is not available for download on the other thread. You can find attached at the bottom of this section ver3.3 which I had used. Please don't use ver3.5 as a user has reported having bootloop with that.)
-Battery +80 charge recommended...the process gonna demand a lot of power.
-Patience... loads of it....
Disclaimer: I am not responsible if you brick or damage you phone!!
Before you flash anything, be sure to have a working twrp full backup of you phone! In case anything goes wrong.
STEPS:
1. Copy the untouched kernel 'modules' folder [found in system/lib/ in your phone] to another location ( for e.g. to your internal phone memory), you're gonna need it later.
2. Flash the twrp recovery if you haven't already and boot into TWRP recovery.
3. flash SchKernel Extra 3.3 kernel mod. It will launch the aroma installer. There will be options as overclocking/underclocking etc..
I left everything on STOCK option, disabled Swipe2sleep, unselected the everything in the optional addition page. Then went to install it.
4. Reboot, and open SuperSU app, go into setting, tap the FULL UNROOT option, this might take a while. The first time, when the unrooting notice shows and it seems that the app is not doing anything, you might be required to exit the app by pressing home button. Then open the app again and redo FULL UNROOT option. If you exit the app and when re-opening it, the "unrooting notice" is still there, then it means it is working. This might take a bit of trial and error.
5. Ultimately, SuperSU app will close. Then you will need to reboot. You will see that SuperSU is gone and that you have no root access.
6. Now, turn it off again to go to fastboot. Connect to PC and flash the stock boot.img via adb to restore the stock kernel.
8. Then, in twrp recovery, mount /system partition and got to advanced >> file manager..
9. Now browse to /system/lib/ and delete the 'modules folder'.
This is because the SchKernel Extra 3.3 kernel mod flashed previously has modified your kernel modules and when you will try to update the OTA, the stock recovery will report that the kernel modules (xxxxx.ko) has be modified and it will stop the OTA update process.
10. Remember the previous untouched stock 'modules' folder you copied previously, now move it to /system/lib/HERE , to replace the deleted folder.
[DO STEP 9 BEFORE - Don't try to overwrite the folder, it won't be possible. It said operation failed for me. ]
Optional: You might also want to delete su.d folder in \system and init.d folder in system\etc
these files were for the custom kernel and won't be needed anymore.
11. Reboot into fastboot mode, connect to PC (if not already), flash stock recovery.
12. Now, you're good to flash the OTA updates. :good:
-Download it, if not already done.
If ever you have downloaded from PC and copied it to phone, and for whatever reason the phone is not detecting the zip file and asking for install.
Just move it to you exeternal SD card and rename it to "ptt.zip" , go into stock recovery and go down the list to "apply update from SD card"
and it should flash the zip file. When done, select the reboot option and it will say reboot to flash firmware.zip and the will boot. :fingers-crossed:
When booting it will take some time (3 to 8 mins), and then go to the "Android is updating - optimizing apps" screen. This might take a lot of time if you have a lot of apps installed. The phone might get really hot during this process.
When the OS finally boot completely there will be an "HTC" screen and an exclamatin mark in the notification bar. NO WORRIES, it is the just the update working. It will go away when the update is fully processed.
After OTA update is done, you can make a twrp backup of the unrooted system, so that you can restore it for future OTA updates.
If some steps are confusing, feel free to ask for any clarification
Hope I helped you. Don't forget to hit thanks

how did you flash it exactly?
Did you flash it thought TWRP recovery?
also...what variant of HTC e8 are you using?

Thank you for this guide. :good:
For the newbies, here are exact instructions for each step. TWRP is required; presumably you have this because you've rooted your phone. (If you haven't rooted your phone, what are you doing here?)
Note that rebooting to TWRP can be accomplished in several ways:
Long-press the power button; when prompted choose Reboot. When the screen goes black, press and hold the Volume Down key. This will take you to hboot; from there choose Recovery.
Enable developer mode from settings, plug in to a computer, and issue the command adb reboot recovery.
Also note that it is prudent to do a full TWRP backup to external storage (microSD, USB OTG) before anything else, so you have a good recovery point if things go wrong.
To copy the system/lib/modules directory, you can use a root-enabled file explorer or TWRP. To do it in TWRP:
Reboot to TWRP.
In TWRP, select Mount. Make sure that system is checked.
Back to the main TWRP menu, select Advanced.
In the advanced menu, select File Manager. Then navigate to /system/lib/modules.
Tap on Select, then Copy Folder. Navigate to a new location - I used /sdcard/Backup - and tap Select again. Don't use your external SD or USB-OTG, they may not preserve permissions correctly.
To flash the SchKernel Extra, copy the ZIP file to your device, reboot into TWRP, and select Install. From there, navigate to where you copied the ZIP file and select it; then follow the prompts as sanijsnj specified.
Removing SuperSU works exactly as described. Don't forget to reboot at the end (although it may not be necessary).
To flash the stock boot, in a cmd window where you have the Android SDK, typically in the sub-folder platform-tools enter: fastboot flash boot boot.img (boot.img from the OTA ZIP).
To delete and restore /system/lib/modules, follow the steps above, starting of course from your saved 'modules' directory and copying to /system/lib.
To flash the stock recovery, again in the cmd window enter: fastboot flash recovery recovery.img (recovery.img from the OTA ZIP).

Roms for GT-I8160P version guide

Hi people, here is a short instruction if you have a P or L version of the I8160 and want to update this (great) old phone. credits to xdas-e
for a while i thought that roms didnt work on the P version, because when installing roms i got the error that the rom was only for I8160, not I8160P. so yeah it is possible, maybe this is common knowledge, but i couldnt find out how before i found this information.
I have not tested this exhaustively but i believe they all should work, because i believe the only difference from the P version is that it has an NFC module.
]------- modify the rom for P version:
1.- Get the custom ROM.
2.- Get the /system/lib/tee folder contents from your GT-I8160P JB installation (from stock rom). You may need root access, although in my case I could simply move trough the hidden directories and copy the folder to my sd card.
3.- Swap the /system/lib/tee folder, and put what you got from step 2, into the zip file of step 1, same place, same everything. You may very well dispose the original /system/lib/tee folder in the zip file.
4.- Change /system/build.prop and introduce a P in every GT-I8160 entry (from GT-I8160 to GT-I8160P).
5.- (tricky one) look for the updater script file within the custom ROM zip file, and delete (or add a P) the first complete entry of the assert command (you shall see some GT-I8160 there). in my case it was located under META-INF\com\google\android\.
------- from here you have successfully modified the rom for the P version, these steps just show the installation:
6.- If you dont already have CWM, get yourself one (I used this one [JB] CWM Recovery 6).
7.- Put both zip files into your sd card; get a copy also of gapps (google apps, play store etc) for the android version of the rom.
8.- Back up all your data.
9.- Swicht off your phone and restart in recovery mode (up volume, home and power buttons pressed simultaneously).
10.- Load from the external sd card the CWM zip file.
11.- Make a full ROM backup to restore if things go wrong. Wipe data/factory reset; wipe cache partition; wipe dalvik cache (under advance options), format /system if needed (see rom instructions).
12.- Install from external sd card: a) custom CM rom; and b) gapps if you're for it.
13.- Restart.
14.- You shall be done!!! (first boot takes a long time)
good luck! my phone was crap with stock and now it works great, so basically it saved me from buying a new phone.. a big thanks to all the rom developers for this device .
