[Q] Update messed up G-Pad

I had stock installed, rooted and twrp install, I downloaded the update and now it only boots into twrp. So i tried factory reset and restoring a backup I had, still nothing. Just now I pressed advanced wipe everything except SD Card, now I have no OS And no backup to restore.
For some reason twrp doesn't recognise any micro sd card I put in, says it cant mount them.
I can't get adb working whilst in recovery. I just want to go back to stock.
Also holding down vol down and up to get into download mode doesn't work.
Thanks for any advice.

Got it into download mode now somehow (rebooting from twrp instead of cold boot) and downloading the stock firmware from LG mobile support tool.

1. Turn off the tablet. (from twrp menu )
2. Push vol+ and vol- same time.
3. Insert usb cable.
4. Release both buttons. Now you should be in download mode.

hi mike_1983, but have you solved with this method?

I was in same situation. And i solved installing stock room with LG Mobile Launcher.
Go in download mode, and then follow this method: http://forum.xda-developers.com/showthread.php?t=2471370 is 100% working.

dont update the official rom if you re rooted or you have a custom recovery, they ll brick your tablet. If you have access to recovery you can install a custom rom and there is no need to go back to full stock (unless ofc you want to keep the stock rom in which case you need to flash it using the lg mobile support tool)

I think I did it by holding down vol up and vol down whilst in twrp, then pressing reboot, system (or perhaps pressing reboot system then holding them down). I'm not sure if the usb cable was plugged in or not. I tried holding down vol up and down from powered off, but it seemed to still always go into twrp.
Then you need B2CAppSetup.exe which is LGMobile Support Tool, you can then download the stock rom, it overwrites everything, like recovery and root.

Made the same mistake : said yes when the tablet proposed me to update. Booted in TWRP.
Tried to flash with support tool but it stops at 95% and tells me in german (!) to remove the battery and try again... I've tried many times (without removing the battery obviously), just the same.
And now I can't get out of the download mode. Everytime I plug the USB cable, it goes to download mode.
Any suggestion ?
EDIT :
I even tried this method : http://forum.xda-developers.com/showthread.php?t=2622777
and it stops giving me a decompression error...
Edit 2 : it finally uncomressed corectly but i'm still stucked at 95% when installing : WPARAM_UPGRADE_ERROR
EDIT 3 :
Using the method http://forum.xda-developers.com/showthread.php?t=2622777 and leaving default parameters : Korean language and country it finaly worked with the V50010A_00.kdz firmware.
My lg g pad is finally booting ! (the battery is totally drained)
Thanks to all !

[Q] Can't update it

Hi, I'm from Italy and my uncle send me an SGH-i747.. I've unlocked it for use my Italy Sim.

You won't be able to get an OTA update in Italy because the update is delivered via AT&T which you probably don't have access to. You would need to have a valid AT&T SIM card in the phone with Wi-Fi access. You may be able to update manually in 2 steps first to 4.1.1 and then to 4.3 which is the latest OS version by following the process in the thread below ...
http://forum.xda-developers.com/showthread.php?t=2387423
Download the 2 stock files for 4.1.2 and 4.3 respectively. Copy both zips to a good quality micro SDHC card
Power off the phone. Place the SD card into your phone. Boot into recovery mode by simultaneously holding down the volume up, power and home buttons. Wait until you see a blue message flash across the screen then release the power button but continue to hold the volume up and menu button until the Android image appears. Install the 4.1.2. Wait for the process to finish and your phone to reboot. Power off again and repeat for 4.3. Hope this helps you.

Now I try, Thanks .. But I've need to Root my phone?

I've tried to update to 4.1.2 but at the restart of the phone, after "rethink is possible" it remain on the Samsung screen... help D:

If you got to that stage, then it worked. Sometimes it takes several minutes for the rest of the set-up menu to come up after reboot. Wait for a while and if nothing comes up, pull out and replace the battery, then reboot into recovery mode. Do a hard wipe/factory reset in recovery mode and reboot.
You do not need to root your phone for this process. In fact, it may not work with a rooted phone. You can, however, still root your phone after the update and there are several ways of doing this. However, first get through the updating process and let's know how that goes.

Really thanks, I've done an Hard Reset and it works.. now i've 4.3 thanks a lot. You can close the thread.

[Q] update to 4.4 from 4.3 +clean some bugs

Hi all my name is Blake and I'm a noob. (Sigh) thanks in advance for answering my stupid questions and being the awesome intelligent human bada$$es you are and helping teach me to better understand and operate my phone! So I rooted my phone a while back (4.3) or at least attempted it but I think Knox or something along those lines was preventing the process from completing so I had a friend help me out to complete the root so I'm still not 100% on how to do this. So I want to upgrade to 4.4 assuming it's better but more importantly my phone has a lot of quirks and bugs that annoy the living crap out of me and I won't waste u r time listing them unless you need me to and I'm hoping updating will solve some of them and if not I'll be back to forum surfing... anyways I'm rooted and need to know how to get to where I can get the ota update and then root it or however would be easiest to get the update and back to being rooted? I tried reading and understanding the existing threads but I'm still learning the terminology and i couldn't quite understand the ones i could find. Also this is probably a stupid question but is there an app or anything that will magically go through my phone and fix any stupid bugs and stuff!

Also to show my appreciation if u guys have like a YouTube channel i can like and subscribe to or anything i can do to show my appreciation I'd be glad to do so just send me a link thanks again you're my hero!

I know you wanted a video I don't have all of the equipment to do so .. this is just a lot of words but simple easy steps.
Best possible solution for you if you really wanted the 4.4 update (nothing really has changed except the basic updates (firmware/modem)
... nothing noticeable except when you click on About Phone lol and you see 4.4.2 and the description of your system. That's really it.
But if you really want to give it a try the best solution for you is:
1 ALWAYS BACK UP YOUR PHONE!
This WILL BE UNROOTED BUT WILL GIVE THE OPTION TO BE ROOTED IF YOU WOULD LIKE
2 Download Odin if you haven't already and download the .tar file for 4.4.2 (the OTA Update)
When you extracted everything and opened Odin make sure Auto Reboot and F Reset Time is the ONLY ones checked.
3 Put the .tar file in PDA on Odin and put your phone in download mode (home, vol down, and power) when it comes up press vol up and it will show downloading .. it may show NOT RESPONDING give it a minute it usually will load up
Attach the usb cable from computer to phone once it registers it (will say added) click start. let it finish and you will have a complete wipe of 4.4.2 STOCK ROM --- UNROOTED!
FOLLOW THESE STEPS (COLOR MATCH) TO BE ROOTED ..... 4.4.2 ROOTED OR 4.3 ROOTED
-THIS IS THE START FOR BOTH --
1 Download your custom recovery (Philz or TWRP) ... I use Philz it's simple and and does everything for you to make sure it goes through.
2 Open Odin once more (same checked) turn your phone off wait for the vibration to indicate it is completely off then put it in download mode.
3 Place your recovery in PDA then attach phone and click start.
It will reboot just turn phone off and enter recovery mode (home, vol UP, and power). If the recovery doesn't show (sometimes it won't due to knox again) Then try again this way:
Phone off, place recovery in PDA, attach phone, and UNCLICK Auto-Reboot and push start. It will show downloading wait for Odin to show pass then boot in recovery from the screen you are on by just pushing home vol up and power. It should load that time.
Once it's loaded...
FOR 4.4.2 - ROOTED
3. Factory reset/clean to install new rom ...
DO NOT wipe cache just simply factory reset ..wait.. done ... clean to install new rom .. wait .. done.
If you do you will get a Status 7 or an error message.
4. Flash rom
5. Reboot
-It may ask you if you want to disable custom recovery make sure you hit NO!
You will need to update SU on playstore. And you should be good to go (had problems the first few times).
FOR 4.3 - ROOTED
DO NOT TRY FLASHING .TAR THROUGH ODIN. It will fail everytime because you can not downgrade firmware through it.
1. You will need to go back to stock unrooted with this HERE (MC2 Download only)
2 Make sure you have the MC2 Download -- or you will receive a Status 7 .. which means you don't have the right rom to update from.
3 Once you're on the MC2 firmware I believe it is the 4.2 version.
4 Turn off phone, enter recovery mode and flash this MC2 to Mk4 Rooted (NEED TO HAVE MC2 first!)
5 Reboot - if it asks to disable custom recovery make sure you press NO or it will unroot it at start up.

Zenfone 2 - Z00AD (4GB ram, 32GB rom) - no update option

Hi
I bought Zenfone 2 - Z00AD (4GB ram, 32GB rom, 1,8Mhz), it works fine but I can't find software update option. Simply it is not where it supposed to be.
I would really like to update it because i heard that battery is better after update. Can somebody give me some advice?
MODEL NUMBER:
ASUS_Z00AD
BUILD NUMBER:
LRX21V.WW-
ASUS_Z00AD-2.19.40.18_20150612_1183_user
044030427_201501060109
0010000500001
Thanks a lot!

hi
i have same problem , anybody can help us?

I hope that someone knows how to help us.

Where from you buy?

I bought ZF2 at GearBest.com. And you?

i bought my ZF2 at TinyDeal.Com

Howdy lads.
I have bought my exact same model from dealsprime and I also had the same issue due to the fact that it's the Chinese model with a flashed WW firmware :/ When I went into the recovery mode it actually said that my firmware was the CN 2.13 version but under the software model details it showed WW 2.15 version. So you can't actually update it OTA because of this sadly.
I was able to safely update to the latest update with ease though, it isn't difficult and I will point you into the right direction.
I am unable to copy and paste the link here due to the fact that I have under 10 posts so type this into google and it should be the first link: "how-to-update-ota-without-bootloop-on-rooted-zenfone2"
This carefully explains what you need before updating and even gives links to each file/programs that are required.
I was very unsure weather to take the risk doing it this way but I decided to go for it.. and it worked every time I wanted to update my phone ^^
BUT! Don't bother with update files. only download the FULL firmware which is over 1gb and just flash it. It will not wipe any of your files or data so no need to worry about that:good:
Also I only needed to follow the first 8 sections so you won't need to do the 9th,10th or 11th sections.
It is always recommended to wipe cache partition after flashing also ^^
This is the only method that has worked for me with this phone model after trying at least 6 other methods which all fail.
Give it a shot and don't be scared! But just read carefully and do as he says ^^

Irish_PXzyan thank you!!! I did it step by step and it worked!
Thanks again.
How can I wipe cache partition?
Can I make OTA update after that, now I see UPDATE option?

The steps to wipe cache at http://www.asus.com/zentalk/foru ... hlight=wipe%2Bcache is a little outdated.
The updated steps of wiping the cache is listed as below:
Switch Off the Phone.
Press and hold "Power + Volume Up", release only power key after your phone vibrates and keep volume key pressed till you see ASUS Logo.
System shows the mode at the top as “Normal mode”.
Change the mode to recovery mode with the help ofvolume keys, select recovery mode with power key,
System will restart and you will see android logowith error message,
Press and hold “Volume Down + Power” key and while keeping those two pressed, press and release Volume Up key. System will now enter into recovery mode.
Select wipe cache partition (volume up/down tomove; power button to select), Process will start and will take approx.8-10 minutes.
After completion select reboot system now.

Your welcome ^^
Now enjoy the updates!!
You will have to do this every time you want a new update so you will never be able OTA sadly, at least from my experience I have yet to find a way to do this.

Stuck on recovery even after flashing ROM, can't boot into fastboot

Hello, I flashed CM14 the other day, and after a problem I had to flash it again. It booted just right, and I remembered people on the CM14 thread saying if you factory reset the phone after flashing it would increase battery life, so I did; But the device didn't boot back into android, and instead went into TWRP. I thought it was just a bug so I restarted, back into TWRP again. So I clean-reflashed the rom, and it didn't even boot then, got back into TWRP. So I restored a previous full backup I had, TWRP again. I thought flashing the MM Blobs again would reflash the boot img, so I did, but the device won't even boot into fastboot; goes directly into TWRP. And I can't do anything. Please help :'(
I have a Zenfone 2 ZE551ML 4gb 1.8ghz, if that helps. MM Blobs too.

You Still Having problems ?
If you have twrp - press reboot - power off in twrp .
Leave off ten seconds -- press power and vol+ -- release power when 2 buzzes -- release vol+ at boot up screen.
You should be in bootloader now !
Quickest way to get back to system and restore a back up is then to use the modder tool by giovix :good:
flash back stock recovery and boot.img from selection in modder.
Then reflash twrp in modder and root again in modder .
reboot to twrp --restore old mm blob back up:good:
enjoy!

Hey all,
Can I use this procedure on a completely stock ASUS_Z00AD phone which is stuck in the bootloader?
We have some very emotional family pictures on the internal memory and can't afford taking chances losing them?
Thanks for any information.

Unfortunately no. It is the wife's phone and i can only touch it when it is broken. You know how it is. All I am sure about it that there are no developer options enabled.

Well , you need to ask the missus if she ever updated it :good: and when because this tool is for M only !
In the meantime ,scroll in bootloader to reboot recovery, press power off once - when it boots to dead android -- press power and vol+ together for five secs , release vol+
you should be in recovery now .
does it say anything in the bottom left corner ? top left build number

Ok i just tested this method just for you on my 551
I have UL-Z00A-4.21.40.184-user.zip.zip(you use your own based on what is stated in recovery) on external sd. remember to add an extra .zip on the end- written on pc too first before transfering sd to phone. then have inserted into phone
I am on .184 M
Then
Selected from bootloader to go to recovery -- at dead android , pressed vol+ and power five secs then released vol+ - now in recovery.
In recovery , select update from sd , navigate to the firmware and proceed.
Took approx fifteen mins and all my fone data was the same.
Again , id like to state , my phone was working normally before this procedure and whether yours will is not guaranteed and the risk is entirely yours , as always

Help guys, my phone wont boot up. It only vibrates when u press power button.
Made a mistake by upgrading my phone to marshmallow. What i din is put the fw file to internal memory, then re start my phone and it detects the system upgrade, press ok and phone goes to twrp recovery to flash the rom. But then after, my phone went off and it wont boot up.

The mistake you made was not flashing back stock recovery first . Everything would be fine now if you did
If no bootloader , you are bricked - lots of unbricking threads on here , 1 by suckhwant and 1 by summit :good:

Very new to this, and having the same problem with my Moto E4. I ended up deleting my os by accident, so I've installed a custom rom and gapps multiple times, but when I reboot after installation, it just goes right back into twrps. Could someone walk me through the steps?
