[LG Optimus Black] ambishop:
Yes. I found that updating a Rooted V10b phone with frozen apps, to v20n had strange behaviour. Once v20n was booted I had Superuser app still showing and I assume su was still there, I forgot to look before I started messing with trying to push su via abd so I do not know for sure. however superuser was there for sure.

in addition my frozen lg bloatware apps were not overwritten. I had no LH Home app as it was frozen by titanium backup, and upgrading to v20n did not overwrite the frozen apps. My only limitation was not having write access. If there was a tool to provide simply write access to my system folder then I would have been able to root I believe.

I tried giving write access with ES File Explorer, as the checkmarks for root and where already checked in that app from before upgrading, but when I tried to change the checmark for root access I was not able to check the box again as the phone was not rooted. I had thought later that I should have tried clicking the write access option first but did not.

I hope my above babbling makes sense
[LG Optimus Black] adxgrave:
no no. I said nooby means N00BY0815 not nobody. You obviously didn't know the story and jump to conclusion that everybody here just try to root blindly. Search for his thread and you will see he root v20n germany with known tool. Don't believe it? Just flash it urself and see. Or flash reddy2006's repack which is based on nooby's nandroid.

Plese read others thread before you make tldr; post.
[LG Optimus Black] 1aca:
Yeah, my bad. I somehow misread that.

I obviously read all the relevant threads, I even posted in some. You would know this if you had read them.

I don't need to search, I downloaded a long time ago. Now tell me, what are those repacks and the nandroid backup proof of?

Sigh... I *have* read them and you would know if you had. It seems to me you have no idea what I was talking about in my post. All you've shown with this post is that you haven't read the relevant threads carefully enough to see I was participating in them and that you didn't even read this post of mine.

The fact remains that all the known vulnerabilities have been patched, ergo the tools could not have worked. Oh, and you need to work on your reading skills if you think that post was too long. You might be missing a lot on online forums otherwise.
[LG Optimus Black] N00BY0815:
As it seems you still dont wanna believe that the version provided by me was a real rooted v20n... just ask redy, i am not able to do a repack, neither change any system information, like the v20b into a v20n... but u can also ask huexxx, as he already should have taken my version apart, in order to do some mods and add some tweaks, guess he can also confirm, that it really is v20n :-) concerning the tools used, i didnt use any other, then mentioned in my thread, so it definitly was a known tool, even if it was possibly combined with any kind of memory leak, overflow or any other bug. And some just call it luck, like myself :-D so, keep on doubting and argmenting, that the tools where patched and so on, but it happend ;-) so take it as it is and let us keep on trying :-)

[LG Optimus Black] donjamal:
hi... found this interesting on bbs.gfan.com

As we all know now LG Esteem3.06 can not V20G to root. Studied what he's run the script, root process is to first get the program through zergRush shell root privileges on the system before further operation.

zergRush is to use a 2.3 system, a vulnerability to obtain shell root privileges. Using the holes need to call the system library libc.so file, V20G this file is placed in / system / lib inside to see zergRush source code found in the 137 line that is written in the path of the file '/ system / libc / libc.so' , so the suspect can not get shell root privileges because out here.

Because do not have to compile the Android C program environment and can not do further testing. Have at hand the compiler environment of the oil can try to code the 137 line / system / libc / libc.so into / system / lib / libc.so after the compile and run to see if can get shell root access, if it can V20G root of success. Also the 2.2 version of the oil or you can look at the 2.2 system libc.so file is placed in what position
[LG Optimus Black] 1aca:
Whoa, hold your horses... Where did I say that? All I said is that it wasn't rooted with the tools that are using exploits that are no longer working. This doesn't say anything about it being "real rooted v20n" or not.

I'm tired of explaining it over and over again, so I'm just going to wish you good luck in trying to get a working exploit out of that.

How am I going to stop you from trying? Why would I want that?

I'm just trying to actually help you to look at the bigger picture here. Even if you or someone else manage to root it again the same way (by luck), what would that accomplish? How would that help others to root their phone? What you need is a reliable mechanism by which v20 can be rooted. In order to get that, you need to understand how it got rooted. "By luck" won't help you in getting your answer.
[LG Optimus Black] N00BY0815:
I know, that rooting by luck wont help anyone at all... all i am trying to do is, redo the method i already did, but this time protocol everything i do, so that everyone else will be able to root it this way. I am not trying to simply get lucky again and redo the root this way, but redo it in a way, that can be done by others as well ;-) so thnx for wishin me luck and as soon as u find a reasonable way to root it, pls post it! Thnx for your constructive criticism, since it helps to understand how some exploits work and why they dont work anymore ;-) good luck to all the others here at trying to root :-D

Sent from my blasting P970 with zeus :-)
[LG Optimus Black] 1aca:
No, it works* because libc.so is already loaded by the time dlopen is called and it will find it in the `solist' cache.

* the dlopen call works, not the exploit...

ETA: As an interesting sidenote, this means that bionic (android libc) dlopen will happily open an already loaded library instead of the requested one if it has the same name but different path. I'm pretty sure that's a bug...
[LG Optimus Black] exe127:
GOGOGO! what is the current stage?
[LG Optimus Black] N00BY0815:
No success, since I gotta learn a lot (tests at university aproching...), but when I have time again, I'll keep on testing ;)
[LG Optimus Black] agramone:
hi! im a noob to android and such.. but after playing with my OB i tryed too root it when it was unbranded and stock froyo, with gingerbreak apk 1.2-didnt work.. updated to 2.3.4 today( finally!):D but i still cand root my device! not with gingerbreak nor with any other apk( all others are kinda to complicated for a noob..my version is v20n..

..As i was reading in this thread ,it seems rather complicated ,if not even somewhat impossible to root this version?

Now for my question:how many people have rooted their device using gingerbread or some other apk ,and how can I root my device?

Tnx.
[LG Optimus Black] N00BY0815:
Until now, only me and some others, who also confirm, that they have made it ;) But everyone seems to have used a different software/programm/exploit to do the root... So there is no way to redo it, except for you try all the methods mentioned in first post and the last pages ;)
[LG Optimus Black] George Jetson:
hey N00BY0815

what u think about this way;

1.install 10e or any froyo kdz and do root with blackjack

2.make factory reset cache reset

3.install 20nkdz without factory reseting

4.try rooting

i will test this way
[LG Optimus Black] agramone:
Tnx nooby,props to you and to every one who succeeded, to all the others, best of luck rooting :D

Ill read on and try some other methods as you said.. :confused:

Tnx for the quick reply though :) if i get stuck at some point, im sure the proffesionals here will be glad to help.. :D

Great site!
[LG Optimus Black] pabgar:
Most likely the result will be bootloop :)
[LG Optimus Black] George Jetson:
yea probably it will maybe I can try with 20a after rooted 20a I install 20n without factory reset.
[LG Optimus Black] agramone:
@nooby:... embaressing.. but i dont understand a word thats been written...

... is it really mandatory to have a full understanding of programming in order to root the OB with v20n?

at first i thought its gonna be just a "one click" action rooting my phone...but as i read on, i i get more confused.. :rolleyes:- probably cos im not aquainted with the more complicated processes.. :confused:

..is it possible and realistic to hope for some kinda apk like gingerbreak so rooting becomes a "one click " action , or am i bound to not root my phone?..

You have done it well apparently, but i am worlds apart from your understanding of the subject.. :)....

Btw, where from germany are you from? i was born in hameln..
[LG Optimus Black] 1aca:
Eventually, it will be a one-click action, once a vulnerability is found and successfully exploited.
[LG Optimus Black] agramone:
.. :) cool! so time is the only problem... that sound good! :D

so i guess ill read on , learn , and visit the forum daily and eventually it will all fall into place...:o( maybe some time in the future ill understand more of zhe info written upthread.. :D

..I would like to thank ALL the developers and the people who put a lot of time and work into making it easier for others...:D

YOU make us wanna know more!:D

and thanx for the reply!

... Sorry, but i have yet another question: the SPB shell 3d, is on the mark

One doesnt need root permission to use the SPB shell 3d if one buys it on the market, right?, meaning SPB shell workes normally without root- if one buys it?
[LG Optimus Black] N00BY0815:
Sorry I dont know SPB shell3d... Maybe anyone else can answer that ;) I am born in bavaria near Passau, maybe u know it, but back to the topic.

I am not a developer and do hardly know about programming, so you dont need those skills, but what everyone who wants to learn anything here needs, is time... most dont take it and want everything to be perfectly served to them, instead of trying it on their own. That's also perfectly fine, since not everyone needs to understand everything, but what everyone here appreciates, is taking part in the community and helping each other out, with tips, suggestions and so on.

So just take time, read a lot and you will soon have the same level as me. Before you dont understand at least the basics, like flashing, rooting and so on, better dont modify ur phone, since it will only ruin ur phone, if you dont REALLY know what you are doing.

But if u wanna have a rooted version of V20n already, flash back to v10x, via the programs provided here: http://xdaforums.com/showthread.php?t=1111771

And then either grab this ROM (modified sock v20n ROM with some tweaks): http://xdaforums.com/showthread.php?t=1111771

Or stock ROM, which has only been rooted: http://xdaforums.com/showthread.php?t=1441901

How to root v10x can also be found in the thread firstly mentioned. How to install CWM to be able to flash a custom .zip/ROM, just use search or google about it ;)

Have fun and use the button below ;)
[LG Optimus Black] jimakos29:
no it wont as flashing .kdz files does not require factory reset. You won't even lose data or installed apps when going from stock (even rooted stock) froyo firmware to stock gb using kdz files.
[LG Optimus Black] agramone:
.. sure i know passau, cool!

WOW! :9 thanx for the info looks like with some reading and understanding ill know exactly what you suggested! :D.. nevertheless, ill take my time and try to do what you advised.. ! Thank you!..

im just cautious.. cos i dont wanna brick it ,but still want a rooted phone( because of some apks.)

As you said, it takes tome ,effort and interest to accumulate knowlledge.. :) and since this is my 1st android , and im extremely happy with is as it is, -im guessing it can only get better after getting into the matter.. :D

Thanx!
[LG Optimus Black] N00BY0815:
True that mate, my first android device as well, but I already took some time to get into the material as u see,when u look at my number of posts ;) but u will also see, that I am also still faaar away from perfect :D

Have fun with your phone and keep on trying to root it guys ;)

On older phones firmware in bin format could extract it to crack. That is, unpack, throw files su, packed. And in a flash the phone already SmartFlashTool with root. Firmware 2.3.3 is in bin format internete.

There are specialists?
[LG Optimus Black] exe127:
I have totally no idea what you are talking about.

Instead, I will sit on my sofa and wait for any talent to bring us root tools to V20
[LG Optimus Black] 1aca:
I think s/he's trying to say that if we could extract/rebuild the install image (kdz or bin or whatever), we could slip in the su binary and the Superuser.apk and have their own tools flash the rooted ROM - no need for exploits.
[LG Optimus Black] exe127:
In other word, I am waiting for that specialist!;)

[LG Optimus Black] adxgrave:
Look like it involve some setting in hidden menu like i said. So, anyone can translate it? I don't think Google translate is good enough for this.
[LG Optimus Black] George Jetson:
1. Download and install the driver

2. Download the archive and extract it to any location on your computer

3. Connect phone to PC via USB ( mass storage mode, NO )

4. In the phone go to Settings-> Applications-> Advanced Options-> Debugging USB ( put a check )

5. The phone number is typed 3845 # * 970 #

6. We go to Port Setting-> USB Switching

7. Appears Competed!

8. We go to our archive unpacked and run the file SuperOneClick.exe

9. Select the Donate Later ( if there )

10. Click on the button Root

11. We look forward to. Phone will reboot

12. The program can hang, do not pay attention.

13. Check if there is an application Superuser on the phone

14. If the application is, then rejoice that you are a person with direct hands!
[LG Optimus Black] fjsw:
Interesting... I use google translate and it seems all following comments are "can't root", "no superuser" ... can anyone confirm it really work ?
[LG Optimus Black] George Jetson:
I tried on 20n neu it didnt work but maybe i missed some things..
[LG Optimus Black] adxgrave:
Test on v20b but failed. SOC "CheckIfRooted" equal to true for my device but false for "CheckIfShellRoot". Maybe those came from various random try from variety of root tools. Maybe i should reflash and start clean.
[LG Optimus Black] fjsw:
I just tried on 20N too (Europe open), doesn't work...
[LG Optimus Black] Redpik:
The archive "optimusfan" is a superoneclick, but with a bigger size than the last one i have 2.3.3. I tried also on 20n german and didn;t work. Anybody on 20A? Maybe works only for that version.
[LG Optimus Black] avci:
Hi. are there any mention about this situation i dont know sorry if there is. If i install V20** on V10** already rooted OS and didnt used Factory RESET (ofcourse :) ) there is SuperUser icon and some programs could see the phone rooted but the phone isnt really rooted. Because if I want to use ROM Manager I can Install CWM bot cant Reboot to CWM even Fix Premision option says its ok.. I tried SOC and SRC with this UGed V20N from V10C rooted and didnt Factory Resetted but no chance to real root.. Maybe more professional hands needed after this situation.. Sorry if this already known ..

[LG Optimus Black] Chuonglepham:
You're correct.

I wouldn't even waste time downloading any of the rooting tools if you're on V20 ROMs until an actual vulnerability is found/reported and a software solution created to exploit this vulnerability.

Until then, don't waste your time.
[LG Optimus Black] repsaj9:
any one who has news about rooting the V20* ROM? I'm particularly interested for V20B :)
[LG Optimus Black] adxgrave:
So far none for v20b version. Either it's the hardest to crack or not many ppl trying root on it. I've been trying on v20v SEA version to no avail.
[LG Optimus Black] exe127:
none of the exploit methods so far can root v20B (Hong Kong Version) now.
[LG Optimus Black] repsaj9:
Too bad :( I've been reading the forums the past days and I saw that there are some people who got to root V20N (is that from Germany).

So can I update my S/W to V20n from V20B using KDZ updater? And then try to root once I'm on V20N already. Do you think it's worth a shot?

after using SOC for many times (but still failed to root), I noticed that the glitch is in this part of the process:

mount -o rw,remount /dev/block/mmcblk0p8 /system > /data/local/tmp/output 2>&1

export TEMPRANDOM=34626

export PS1=END:$TEMPRANDOM;cat /data/local/tmp/output

mount: Operation not permitted

I used Psneuter, gingerbreak and gingersnap on different occasions and they all had this in common. The exact error message maybe different depending on the exploit but the common denominator if you'll notice is that it stops at the mount operation. dunno exactly what it mounts though.

is there any way we can tell this to SF?

[Hardware Hacking General] trandi:
This post is about a simple idea: take a cheap 3 colours Ikea night lamp, hack it by replacing its original MCU and adding a cheap serial bluetooth device and then write a simple Android app to control the lamp remotely from your phone !

This is just the beginning, imagine the possibilities once the phone has direct control over the colours and their respective intensities. You can make it light up in sync with some music, you can make it change colours depending on some e-mails you receive or your Facebook status, etc. ...

You can find more details as well as the code, on the original blog post (I know I'm not allowed yet to post external links, but it's definitely not spam and I can't really just copy and past all the stuff and code examples from that blog here...):
