I need root too! I wonder if any of the ics exploits will work with this?!

I hope someone does something with this tablet. Would be great. My kids just got one but it don't seem like you can do much.
Barely any apps, any sites I try to go to its blocked. My daughter doesn't want it anymore because you can't even use Facebook

I just found the recovery key combo on this mutha....
Vol up + home + power

Yeah i bought one for my son and i cant even get it to go to the lexibooks app store. I wonder if we could find out the chipset and port a stock nexus7 rom to it or something. Maybe even create our own update.zip
Poop splash gives you AIDS... and an iPhone

I've had a go at compiling aosp before... I'd love to give this a try.
I've been looking for exploits so we can have root.. but there's no point without first having a working clockworkmod recovery. Because u couldn't backup or flash another ROM without it.
If we knew what chipset it was based on.. it would give us somewhere to start. Also some source code would be nice.
I'd be happy to do some builds and test.. but I would need to know I have a backup I can flash if all goes wrong.

Hi,
I did this and the screen shows an android laying down with the cover ("hood") open and an exclamation mark inside a red triangle. What does this mean? Can I do a factory restore? Please help, I got me one of these at a flea market with the plan to give it to my daughter and now it's useless, but she saw it and is all excited about having her own tablet and I'm going to have to buy a new one if I cannot make this one work. Any help is highly appreciated. Thanks in advance.

I had same problem and asked the customer service.
Here is the reply from them.
Please find the steps to unlock the tablet:
Select the settings icon in the corner of your tablet.
It will ask you for your password, leave it blank and the keyboard comes up.
On the bottom of the screen there is a small icon of a keyboard, press on it and then you will press on "set up and input" the settings comes up, press on "back up and reset" then "factory reset" then "tablet reset".
The tablet will be reset in 3 to 5 min, let it restart then put a new password.
Please be aware that if you do a factory reset, the tablet program will be restored but all your datas and applications may be erased except the applications installed by default on the tablet.

Did anyone get theirs rooted at all? If so, could someone help me out? I was trying to put CWM on mine and it seems to be bricked. I can get into flash mode, but have image to flash. So if anyone is rooted, hopefully we can use DD to dump the stock image.
Thanks

If anyone is still interested in this thread, I just acquired a little MFC270EN and successfully rooted it with KingoRoot. I was able to remove all the little games and annoying bloatware. I haven't tried flashing another version of Android onto it, but it's working fine and I'm using Google Chrome (I removed the Lexibook browser with all its "safety" lol), checking my Facebook and I just installed Link2SD to give it some more space.

[Q] Big problem with my Play Store on my Nexus

Hello everyone,
I rooted my device ( LG Nexus 5) a few weeks ago, then I installed an app called "Cracked Play Store".
Until then, no problems. Then, bored by the new icon of the cracked play store (a yellow smiley on a bag) I decided to unistall the app and from then my Play Store is not working anymore . I'm very upset about this, I've searched all over the internet with no solution. I tried all possible things (clearing cache, disable the app,....) but none are working.
So I'm now asking to anyone a possible way to recover my regular properly working Play Store . I was also asking myself if it was possible to replace the play store install folder by a properly working one and if so could someone send me those files
Thank you in advance for the help
PS: I'm a french speaking, so excuse my possible mistakes

trying to get apps for free i see? you know people work on those, put time into it. if you put time into making an app, how would you feel if people were stealing it?
anyways, boot into your recovery, wipe your dalvik. then boot up, and install a fresh play store apk.

so how did you root? maybe you only unlocked the bootloader? if you are using the default recovery, then you could not have flashed the su binaries. you need to flash a custom recovery for that, either twrp or cwm recoveries. stock recovery doesnt give you an option to wipe dalvik, only custom recoveries do.

Just reflash the factory image and take it from there. We have no idea what this cracked play store may have modified, and simply clearing cache/dalvik may not be enough to reverse whatever it changed. In the future don't download warez, it's not not fair to the developers, and as you can see they can mess up your phone. If you want to download paid apps, you can get your parents to buy you store credit at the Google Play store.

He could have just boot in to custom recovery via adb without flashing it and use it to install superSU binary. I do it all the time. I'm rooted and running stock recovery right now. No offense, just clarifying it is possible..

[Q] Stuck on google loading screen + computer won't recognize phone

First off thanks to everyone who tries to help me out, you don't know how much it is appreciated!
I will try to keep it short and sweet, I installed a rom that did not work and now my phone will not load past the boot image of the google "colored circles", I have tried to connect my phone to my computer to drop new rom files in my phone but I am unable to do that because my computer does not recognize my phone being connected it makes a sound when I plug it in with the usb but doesn't show connected even when I jtry to flash a new rom in ODIN. I currently have T-Mobile and have CWM Recovery that I am still able to boot into. I used a online backup app through google play store to back up my phone before doing anything, and I was under the impression it was going to also save it in my phone and didn't my fault for not double checking. How do I fix this problem I know someone more SAVY than me can probably fix this easily so once again thanks for the HELP.

Well, Odin is only for Samsung phones. So don't use that. I recommend downloading the factory image (there is a sticky for it), and do a little reading on how to return to stock. It's all the same sticky thread.

Why are you using Odin? That's for Samsung devices. Do you have a nandroid backup you can flash in recovery?

I wasn't aware that ODIN was only for Samsung but now i am informed on that thank you. As far as the nandroid backup goes as I said I used a online backup app that backs the nandroid in the cloud and i was under the impression that it would backup a copy to the system as well.....well looks like I didn't do my due diligence because the app did not save anything to my sytem files on my phone. So no I don't have a backup I can flash in recovery SURE WISH I DID AT THIS POINT!

Look in the general forum for the tutorial on how to return to stock. You can probably get by by just flashing the system.img and rebooting. That'll save all your data. See the second method in the tutorial and just use fastboot flash system system.img

Ok, I figured it out and got my phone back to stock with 4.4.3 installed rerooted and applied the tether fix, and audio fix. What it was is that I had to redownload the ADB + ADB Driver then that got my phone to where it would connect to my computer then i was able to flash the stock ROM! It took me longer than what I wanted because I'm use to using samsung phones and flashing with ODIN. Thanks to everyone who replied with some help.

Help, I can't get past the WIFI screen and I can't flash a new rom on this phone

Hello guys,
I need your assistance with this issue. I got this Boost Mobile LG LS770/Stylo phone from eBay and when I wiped/restored it to clean everything from the other person, the phone still wants me to enter the information from the previous person before I can use it. Of course that is not an option. I tried.
Also, since I am unable to get to the Android OS, I cannot put it in debug mode either. So I tried a few things to no avail. This is what I have done so far:
Put the phone in ADB mode via recovery - Done, but I am unable to sideload anything. I get this error.. "* cannot read 'sideload' *"
Put the phone in download mode "Fireware Update" - Done, and I can see my port as COM3, but when I run the next step, I get a message that says... "Hello, my name is LAF....." and nothing happens.
I tried using the LG one click root tool, but that requires the phone to be in USB debug mode and like I said before, I am unable to even get to the welcome screen in android. I can't get past wifi setup in reality, I can't even skip it.
I have been at this all day today. Can you please help me out? I really appreciate any help you can provide.
Thanks

You need a USB-OTG cable and some files. If you have a USB-OTG i'll reply with what you'll need to do. Also, have you contacted the eBay member letting them no they FRP screwed you and you basically own a brick now?

Also, I forgot to respond to your question. I did contact the eBay guy or lady that sold it to me, but since I'm the one that did the wipe, they are not taking responsibility and I get it.

Thank you for the suggestion , but this method does not work. I have already tried this and after the tool went through all the steps, it still asks for the previous account. I have found on some other forums that LG patched this flaw a few months ago and it is no longer possible to bypass FRP Factory Reset Protection. I guess I have a rock until someone can figure out how to bypass this "Feature", which in my opinion should be illegal because it forces people to buy devices from carriers only and you can no longer sell your phone online to anyone, as you cannot give them the account.

It didn't work for me either... the last security patch disabled user from the settings menu. I did find a way after many hours of work.
Basically once I got to settings I clicked unknown sources and then enabled USB debugging and oem unlock. After that I flashed twrp and then a rooted system image. After that I used http://androiding.how/bypass-google-account-verification-on-lg-g4-g3-and-others and it worked

I honestly don't remember. I'll try to figure it out and get back to you. I think it was through the keyboard. I returned the phone already so I do t have it on front of me.

Web trust me i went crazy with this for 3 days. My friend gave me his Stylo from work to unlock and i had this same issue. Flashed back to 5.1.1e,i,j, using kdz files and all the exploits that these guys are using have been shut down. If your on MM forget it. The only thing that worked for me was that tool i linked in the other thread. I hope your wrong on the virus part, ill check my laptop, but your the first person to mention that. Either way i flashed back to 5.1.1 from MM, used the tool, rebooted and it worked i signed in with his gmail.

I understand and I apologize if I sounded like I was shutting your advise down. That was not my intention. I was just stating what my virus tools detected and my experience. Regardless, I decided to ignore the virus warning and let the tool run and do what the steps on the word document stated. It went through all the steps without issues and I got the same matching screen as in the tutorial document. However, after I reboot, I still get the same screen that reads, login with a google account previously associated with this device.
Now, the one piece I'm not sure I understand from your message above is the part about flashing to 5.1.1 from MM using kdz files. How can you flash the phone when you cannot get into the settings to enable usb debug mode? I have tried everything. I even downloaded a rom file image that I placed on an Micro SD card and tried running it from recovery to no avail.
Maybe you are correct and I am just missing a step. Would you mind expanding on the flashing 5.1.1 from MM part? Maybe what steps and files you had to use?
Also, I'm not sure I understand this portion of your message. You signed in with who's gmail?

Samsung Tab 2 GT-P3100 bootloop and odin fail.

My TAB 2 7.0 was not rooted and was in the bootloop all of a sudden. The issue is when it reboots, it lets me enter lock screen password and when I try to use something - It reboots. I tried to do the Clear cache partition and Factory Reset from android boot menu (power + volume up button) which says that DATA WIPE COMPLETE but when I reboot the tab nothing changes, not even the WIFI connections and their passwords. The WiFi remains on and connected to my router.
I deleted those connection from Settings but again it reboots and all deleted wifi connections (which were successfully deleted) are back with their passwords.
I also tried RESET DEVICE from settings, it asked me for my password but when i entered it and tapped on reset my device option - BOOM! it reboots again without resetting.
I searched a lot on net and tried ODIN option with proper firmware but of no use. And most importantly, I did visit authorized service centre before doing any of these, they returned it after trying couple of time to flash it and asked me to change the motherboard(Which would cost me about the price of good android phone - $120).
Can anybody please suggest me any other option than changing the motherboard (which is way much higher than my budget). The option you suggest may be hardware repair or anything else, I may not be able to get it done myself if it is hardware thing but atleast it will help to search the repair option by precisely telling the guy (technician) - what to do?
I have posted this after i saw mentions online about this forum and experts here, I hope you guys help me out as this TABLET is of great use to me.

I never encountered a problem like this before but 2 years screwing with my tab (well bootlooping it with myself) I would suggest rooting it via Odin and Flash TWRP (CWM works too but I prefer TWRP) through odin as well.
After that find a custom ROM, preferably a stable build since you'll be using it for daily use and flash it using TWRP. I would suggest downloading SlimKat or Cyanogen Mod 13 and GAPPS.
You can find a lot of guides (some are step by step) about rooting it through Odin, and flashing TWRP on your tab.
As well as custom ROMS and how to flash it.
Tell me how it goes dude. Goodluck
Edit:
Hmm before flashing custom ROMs, when you try to flash a firmware. Did you make sure that you're using a correct driver for your PC? Samsung Kies does the job but make sure to close Samsung Kies in order to avoid conflicts with Odin. Make sure also to switch your tab to Download Mode when you flash with Odin.

Factory reset but asif nothing happened? I'm sorry but your tab has the dreaded eMMc bug. Only an emmc replacement or a new motherboard can fix it. Sorry.

Dude, firmware flashing was already tried by the technician at the authorised service center, even he couldnt flash it. I tried flashing as you said. But when i went through all the step by step tutorials on flashing or rooting through odin, they all wanted me to turn on the developers options in settings which I can't. Even if i manage to do that, it will just reverse right away after reboot.
The TWRP thing and rooting through odin that you told me are the options left with me. But I am not familiar with all those things so It would be great if you can share any link about the step by step method.

Factory reset but asif nothing happened? I'm sorry but your tab has the dreaded eMMc bug. Only an emmc replacement or a new motherboard can fix it. Sorry.

New motherboard is way beyond my budget, so I am left with only one option i.e. eMMC replacement. Is eMMC readily available in the market, if yes then is there any trusted brand or something like that.

Unfortunately, I am not familiar with eMMc replacement although @Android-Andi does have a friend in Austria who can replace/upgrade it for you according to one of his posts.
Although if you ask me, you're better off buying another more recent tablet.

Thanks man. At least now I know what the issue is and what may be the best solution. I am from India so will have to search someone who replaces eMMC here.

It's only 11 screws & 25 bucks (USA) for a motherboard
