[GUIDE]One Click Return to Stock i9020t/23

This script returns to unrooted, factory state android 4.0.4.
1. Download this zip - Quicker download here:
http://www.mediafire.com/?pzrzrt3583rgbmf
2. Backup your phone (everything! sd, apps, games etc).
3. Plug in your phone, turn on USB debugging.
4. Unzip the downloaded files.
5. Open run.bat
6. Type in Y then press enter.
7. It does the rest.
Had to do this since i'm sending off my phone to samsung, basically used this:
http://forum.xda-developers.com/showthread.php?t=1167819&highlight=unroot
and updated the images for 4.0.4 and for i9020t/23 (this won't work for nexus 4g or i9020a). It worked well for me so I thought someone else might find it useful.
If you're having problems it's probably because you haven't installed the windows drivers correctly, I can't really help you there (google it or something!)
If you want to thank anyone, go to the other thread and thank michaelpeerman. All credit goes to him.
Edit: By request, someone wanted the same thing but for 2.3.6, so here is the link for that

Hi there!
Is the One CLick 2.3.6 edition compatible with 9023?

I have a i9020T stock 4.0.4 never rooted. If I run the 2.3.6 script,will it go back to stock 2.3.6 without problems?

My understanding is that you require root to flash any ROM, this would be no exception. It wouldn't be that hard to root and then run the tool though.

But there'll be no problem rolling back to 2.3.6 from stock (rooted) 4.0.4?

Hi,
I got a really f******g problem with my NS. The power button is out of service. Thus my only aim is to get back to the unroot locked bootloader rom in order to send it to samsung.
I tried to do that manually with cmd.
I tried via Odin
I tried via your one click zip
I used my computer (the one i used to root it for the first time, guessing the drivers didn't change). Everytime, the command got stuck at 'waiting for device'. I thought it was a driver problem, tried to reinstall sdk, reinstall drivers. I'm still blocked at waiting for device.
I tried with another 'virgin' computer. I installed PDAnet to get drivers and make sure they work. (tried CMD or with your one click zip..) I'm still still stucked at waiting for device. However, my device do is recognised by both computers..4
Any idea?
Is my ****ing power button messing around?
Two days i'm drudging on this.. I'm thinking about suicide by now..

Sorry mate I really have no idea, maybe you could try calling up samsung and ask them if they would repair it even if you rooted? It is a developer phone and so they must understand that most people with a Nexus S root it..

I'm looking to sell my NS so wanted to get it back to stock and this script worked perfectly. Thanks so much!

before u upgrade to 20a u had adb drivers installed ? i dont know if u needed them with the older firmware because when i bought it it was already on 20a. My only issue and i couldnt unlock the bootloader was the drivers. after that just one click in the all in one tool , did the work.

well u r not doomed inside a developer forum. i believe as soon as someone see it , will help u.
for now try do what you can do since u have bugs , to help yourself have less bugs. root is fine. if google playstore doesnt work, then download latest gapps and extract them. manually install them in the system->app. go manually delete all dalvic-cache and cache of all apps. reboot and fixed. if u have other bug tell me maybe i have an idea to help to that too until u find a solution to the bootloader problem.
---------- Post added at 11:45 PM ---------- Previous post was at 11:40 PM ----------
also there are replacement apps for the original 20b. maybe u cant unlock the easy way , maybe u cant install other rom, but definately u can modify the original rom the way u like it, manually. u can use alternative launcher, alternative task manager, alternative everything. modify the status bar. u can do magic if u have time to spend !!!

you didnt get what i said. u will do it manually. to have a button and do it all isnt manually -.-
i say again. fix your bugs manually ! u r rooted right ? u said that. then use a root explorer ! download latest gapps released at 21/08, open your root explorer, extract them. go to extracted ~system/app , copy / paste in your system / app the apks , navigate to data/dalvik-ache or cache/dalvik-cache delete all of those files. then go to cache or to your task manager and delete all app cache. reboot. thats it. this was fixed. the same way u can download mods or alternative apps, install them manually, delete the originals if u dont want them ( first disable them and test if the alternatives work ) , reboot. its easy. the system apps that need root access always go to system/app and the odex is created automatically after reboot.

[Q] Back to stock w/o backup

Hello,
Is it possible to go back to stock when I have not backed it up?
I am currently using Cyanogenmod 10.1, but I want to go back because the battery use is absolutely terrible.
The phone also charges really slow since I installed Cyanogenmod. (is this possible?)
android version: 4.2.2
Kernel version: [email protected]
Thank you

Install pengus77 or tonyp cm10 and you'll never want to go to stock.

Yes it is possible. Use smartflash to go back to stock rom.
You find everything (smartflash, drivers, stock roms) here https://drive.google.com/folderview?id=0B82zQdUvU4pJeW5rU1JzQVcwYUE&usp=sharing
Start smartflash.
Select ROM copy D/L tab.
For CP bin select the smaller file which ends in .fls.
For Ap bin select the larger file which ends in .bin.
Turn off the phone.
Press and hold the volume down when you connect the usb cable to your phone which is already connected to your pc.
Install drivers if didn't do it before.
Press start in smartflash.
Sent from my Nexus 5 using xda app-developers app

I followed your steps(i've chosen the rom from 30 nov 2012) , but I can't click on start in smartflash it stays grey.
My phone gives the message: S/W Upgrade Please wait while upgrading...

The grey thing happens because you don't have the drivers installed.

It worked :good: thank you !

I also had the problems you describe with the battery (slow charging and draining very fast). The problem was that I was using CM10.1 with the Old Bootloader. When I updated to the New Bootloader and flashed "tonyp - T-Build 05" (CM10.1), it started charging normally and battery usage is very very good. Try it and you won't regret.
You can also flash TheROM (CM10.2) because it is very good. The only problem is the bluetooth calling that isn't working (sending files and listening to music works). This is the only reason I don't use the TheROM (CM10.2)...

It was actually risky to try this root method for my aunt's A3500 HV as I had just bought it for her on 24 Sep 2014.
Originally I bought the tablet with android 4.2.2 and it was get rooted by RootGenius__lenovohome v 1.9.6. When I found this thread, I updated the tablet into FW version A3500hv_a442_01_32_140805 (android 4.4.2) by flashing tool. When it was successful updated to this version, I was noticed via OTA a newer version, FW A3500-HV_A442_01_35_140911 immediately after the first boot. I went ahead with downloading and updating the newer version by OTA. I felt it was so much better with the latest version with rapid lock GPS, better screen display quality and better sound quality as well.
As I was afraid to get brick the tablet in this thread, I tried to root the tablet again with RootGenius__lenovohome v 1.9.6 again but no lucky. As the result I decided to give me a chance to try the root method in this thread for A3500 HV with my own risk as I thought it can be unbrick by re-flashing a FW. Luckily it was rooted successfully with the instruction in this thread. It was a magic. :good::good::good:
There you go some screenshots.

Thanks for the reply well I new that they had put some extra security in the new kitkat version so that you can not root but when you use the recovery then you are installing the su file when android OS is is off so the security can't catch you
All right one last question have you tried making a nandroid backup and restoring it up until now if so and successfully please say so
Also if you do not know what a nandroid backup is it is just a backup of an entire operating system and can be used if the system gets bricked and it is totally harmless all it takes is 5 min since you had done the dangerous part and if that works can you check out nandroid restore because if the backup worked in success then there is a 97% chance that clockworkmod restore works o and there won't be any loss of data because you are doing a restore of all the data you backed up seconds ago
If there is a single error message after even after the backup and restore is finished please report it
The backup is totally harmless so if you can just check that I and all the HV version around the world would be very great full thanks in advance.......:fingers-crossed:

Actually I'm pretty sure that KK FW of A3500H does work on A3500HV then I think that the root method will work on A3500HV either. The only different thing between A3500H and A3500HV is call function, I think so.
I did try a Nandroid backup on FW 4.2.2 actually by using the recovery in this thread before upgrading to KK FW. It took about 10 minutes less for the backup procedure to be done without any error and it was written on CMW/BACKUP folder on external SD card (16GB was used). I noticed that the backup steps were similar to any Nandroid backup on CWM recovery: backup boot, recovery, system then data... later generating MD5 checksum. I haven't tried to restore this backup as the update KK FW works really great.
I also tried to flash zip FW (the latest one with build number ​ A3500-HV_A442_01_35_140911) which was found on this link https://yadi.sk/d/KY44k2XDba5Mw from the Russian Lenovo Forum when the tablet was on FW 4.2.2. However, it was not successfull as the recovery said that there was nothing found on the zip to flash. I had no idea about it. Maybe we cannot upgrade to KK by this way when on JB FW or this CWM recovery (which is customized for A3500) can't be used to flash rom. Then I have to upgrade it by flashing tool and FW found on this link: http://lenovo-forums.ru/topic/7809-прошивка-lenovo-a7-a3500hv-a442-01-32-140805-row-call/
Link to the forum: http://lenovo-forums.ru/forum/289-прошивки-lenovo-a7-a3500/
The tablet is not with me now as I just bought it for my aunt so I don't have a chance to try Nandorid backup when it is on KK FW. If there is a chance to do so, I will report it shortly.
I think it would be great if we could have flashable custom rom for Lenovo A3500HV via offical custom recovery.
Good luck!
Cheers,

Problem when tried to update from CM13 20160502 to 20160506, my phone "dosnt work".

Problem when tried to update from CM13 20160502 to 20160506, my phone "dosnt work".
Hello guys,
Well, i was using CM13 for a long time without problem, but yesterday i tried to update to 06 may 2016, and when i clicked in "update" option, it restarted and the screen started to flash, i waited for about 10 minutes and it didnt changed, so i removed the batery and tried to start again, and it just loop in start screen forever, done a factory reset, and it worked, well, it was on, but a lot of problem started, i couldnt open de SD card (once i selected to use sdcard as internal, the worst choice of my life), the keyboard is not working.. i cant use my phone :/
I can start my phone, but cant access the SDCard and cant use the keyboard..
I really dont want to reflash a stock rom and TRY to root it (the last time it took me 4 days to root it, and i really dont remember how i did it, because none of the methods i found worked, just one from a russian forum worked to me using the lg stock rom 5.0.2), i'm about 2 hours searching for a pre-rooted 5.0.2 android rom for lg l90 d410hn, but cant find either :/
Can some one please save me ? I really LOVE CM rom and dont want to get back to stock rom, and i really need my phone working again :crying:
Thanks in advance!
Have a nice day.
Apparently i cant open it in download mode too.. if i press volume up + power, it just starts normally, without entering download mode :/

REALLY thanks man, this should really have done with my problem, but.. i bricked it when i tried to factory reset, well, i did the [GUIDE] unbrick... and its on again, but with android 4.4.2.
In the lg-phone-firmware theres 3 v20 version, v20a, v20b and v20c, wich one of them i can root with the one click root method ? Or how could i root it in the v20c version ? The last time i rooted mine with pure luck, using a russian forum (that i dont remember the name...).
If you know, or any one, i would really appreciate the help!
Thanks again my friend, if i werent soo anxious, you would have saved me hahah

Her is the link for the root(I AM NOT RESPONSIBLE IF SOMETHING HAPPENTS TO YOUR DEVICE) http://forum.xda-developers.com/lg-l90/general/root-lg-optimus-l90-44-2-5-0-2-android-t3110257

You can also root any L90 Lollipop version, including 20c, with KingRoot. Download it from XDA.

There's full 20c bootstack AFAIK, you can use any other aboot to flash TWRP then flash bootstack.

D410hn is different than D410, hn variant is dual SIM and has NFC, its bootstack may have problems with D410. I suggest that you use latest bootstack for your model.

Which TWRP did you use? Try another version, shoxxy's version may cause error 7 with some devices.
Also if you are still on an old version of KitKat you may need to flash the full bootstack to update modem partitions as well.

Yep, i tried with the shoxxy version (http://forum.xda-developers.com/lg-l90/development/recovery-twrp2-7-1-0lgl90w7xxshoxx-t2826150)
Do you know any version that is not having this problem ?
Thanks for your reply, i'll unbrick my phone again lol

Your phone's system partition is empty, that's why it's stuck with LG logo. Simply copy the other (installable) TWRP zip and flash it with current TWRP and it should work. (Reboot afterwards, of course)
I have used the DatkBlue version from the same thread you linked, not sure if it will work for you. There is another version by GrinningFerret IIRIC.
There is also a workaround where you edit the ROM zip to bypass error 7, search forum.
Again, no need to revert to stock now. Good luck.

Reading your first post, it seems that you micros may be bad. Are you using another one or at least tested that one for hardware errors?
---------- Post added at 11:03 PM ---------- Previous post was at 10:51 PM ----------
Actually the other TWRP version was built by SlimShaddy:
TWRP-3.0.2.0-w7-05-04-2016.img | by SlimShady's for Optimus L90
https://www.androidfilehost.com/?fid=24459283995313433
It's in IMG format, so I think you can't flash it directly in TWRP.
