Several months ago I purchased the nexus 7 2013 wifi version. In my tiredness after a long day I unlocked, rooted then flashed a custom rom (aokp) my build numbers is KVT49L instead of KVT49H. I must have flashed the LTE version in error.
I'm trying to upgrade from 4.4.2 to 4.4.4. Wugfresh toolkit doesn't work, also unfathomables tool won't work either.
I have been rooting, swapping kernels, unlocking bootloaders and flashing custom since the Droid x days.
I assume I need to use ADB? I am having a hard time finding specific instructions on how to complete this minor upgrade to 4.4.4. In afraid to try anything being on the build for a different version of my device.
any suggestions are appreciated.
I apologize in advance if I left out any critical info regarding my situation.
Edit:
Also are the tool kits not working because I'm on the incorrect build?
K... so, does anyone have any thoughts about just flashing KVT49H rom over what I have?

Why isn't the toolkit working with flash stock and unroot? You should be able to select the option that says it is in a boot loop... And for current version, you can select anything you want - that is what it will flash when you do the flash stock and unroot.
If that doesn't work, where specifically does it fail?

It goes into bootloader mode and does not come out. Toolkits worked fine on N7 v1. I am attempting to un root and revert to stock.

Toolkit works on v2 as well. When you do the flash stock and unroot, you have to select the option that says your phone is soft bricked.
If that doesn't work, when you are in the bootloader, are you at least able to use the volume buttons and power to select recovery?
Thanks Mike, I'm going to try that

Soft brick option did the trick!! I was also able to restore to KOT49H. Thanks my friend

My p930 is rooted and running the latest CWM recovery and CM10 nightlies. The screen is broken and I 'll need to send it in for warranty/insurance claim. I've run a CWM backup, and transferred that to my PC. Now I need to return to stock/unroot.
This thread, along with other unroot threads, are kinda old. Is SOC > Unroot still the best method? Has anyone unrooted from 4.1/CM10? Are there any other known methods?

If all else fails you could use the LG update tool to update to official ICS... I personally don't know if there's an easier way.
On the broken screen thing, how much are you being charged to replace it? You can get the digitizer glass/frames on eBay for around $40-45. There is a nice guide on how to tear-down the phone floating around the general forum which I have used three times so far : But it's pretty easy to do and would save you some time of being without your phone... and save you the hassle of having to unroot and all.

Best thing to do now is just update using the official LG updater to ICS from download mode. If it refuses to install for any reason, flash the V18f ICS update first.
I'm also wanting to go back to the stock ICS on my optimus LTE. I'm just not 100% sure what I should flash first. Currently if I connect the phone to the LG mobile software it says that my phone is already up to date. Where would I be able to get a V18F ICS update? And also once I've done that will I be able to point the LG software to Telus I don't remember since it's been so long since I upgraded my phone.

Then you should be able to follow the unbrick guide to downgrade to GB, and instead flashing CWM and carrying on from there, try to use the LG updater while on stock GB.

The v18f version is here: http://forum.xda-developers.com/showthread.php?t=1668476
The nice thing about this is that this exe will flash no matter what ROM you currently have installed. Then, after installing this, the official updater will recognize your phone as out of date and will allow you to flash to the official v20c update easily.
Seems to want to update to V10J and that's about it, never get's to V20E. Also after the update it just stays at the Telus splash screen.
I was able to load the ATT V18F no problem and then get to the point where the LG software wants to update but that's where it end unfortunately.
Guess I'll keep trying and see how it goes.

Oh, that's actually fine. You just need to do one more thing: after you get stuck on the splash screen, pull the battery and put it back in. Then hold down volume down + power button to turn the phone on (same way you access CWM if you have it installed). Then press power button twice to confirm and your phone will reboot after a little bit and should work fine from there.
HOWEVER, if it's not even the version you want, then that doesn't help you much. What version of the phone do you have? P935 from Telus?
I have a AT&T Galaxy S3 and I have been searching the forums for a solution to this, and have come up with some answers. From what I've gathered I am by no means at the end of my ropes at recovering the device, but I'm having trouble actually making any ground on it.
I read that flashing back to stock using Odin would get me by the yellow triangle of death, but I can't find a stock download anywhere. All the links I've found link to hotfile, which isn't up anymore so that's been creating some problems. Maybe I'm wrong on that, but all I need is Samsung's stock 4.0.4, right?
I have a HTC Sensation and Nexus 10, both rooted, and I thought I had a pretty good grip on what direction was up from working on those devices but this S3 really has me stumped. Any help would be greatly appreciated.
It might be better if you could mention what exactly you did to get your device to the state it is in.

Woops, sorry. I flashed CF-Root-SGS3-v6.3.tar using Odin and the process failed.
What OS were you running before trying to root? If it's 4.3, you won't find an AT&T stock 4.3 rom to re-flash your phone. Do not try and flash anything with a bootloader that is older than the phone's current bootloader as that will brick it.

In my opinion, don't go near 4.3.
I'm sorry, I feel like this should be obvious, but how do I know which of these I want to flash?
So you're sure you were on 4.04 when you tried to root? If that's the case, I would try the July version.
By flashing in Odin, you will wipe everything off the phone, including your data.

100%. On the box the SW-VER is listed as I747UCDLK3, should I still go with the July version? And I use the PDA function in Odin for this, correct?
Wait, DLK3 is 4.1.1, not 4.0.4.

Huh. I reset the phone to factory settings last night before I started tinkering with anything, and it was for sure listed as 4.0.4. I could be mistaken though, but I'm fairly certain. I'd rather not go against what's listed on it's box though. I'm sure the factory knows better than me.
I'm not sure what to do now. Does the imei # match the box?
That it does. I have to wait another 2 hours before I can even download the stock firmware, so it'll be awhile before I can even try flashing it.

I'm not sure what I would do in your situation since the box indicates you have 4.1.1 while your phone has 4.04.
You were right, I talked with someone who was there last night when I was working on it. The phone is 4.1.1, thanks for the catch.
Okay, at least it is definitely not 4.3 which is good.
What you can do is install a custom recovery and flash a custom ROM.
So should I not even worry about going back to stock then?

Hello,
I have a Xperia ZL C6506 with a locked bootloader. I would like to unlock it, or at least root the phone.
Bootloader unlock allowed: No
Android 4.4.4
Kernel version: 3.4.0-perfg1bb39c2
Build Number: 10.5.1A.0.292
Country: Canada
Flashtool will not root the phone, even trying Towelroot V3.
Seems like every answer I find on XDA says something about my phone is always stopping me. Either 4.4.4 is a problem, or BL locked, or 0.292, I can't root... What am I missing?
Do I have to flash a new kernel or rom? Is it even safe to flash anything, even if it is stock, on a phone with a locked bootloader? I do not want to brick.
Thanks in advance for your help!
I found this forum: http://forum.xda-developers.com/xperia-zl/help/rooting-xperia-zl-t2994781
But,
I read this: http://forum.xda-developers.com/xperia-z1/development/newroot-z1-t2807092 it says: "Newroot work with all kitkat firmwares but doesn't work with latest kitkat *after 108) .133, .157... firmware or with old JB firmwares!!!"
This is the only thing that I have found that I have not tried, but I am hesitant to try and flash an old kernel on a phone with a locked bootloader. Is it safe to flash anything on a locked bootloader?

Yes, it is safe, as long as you know what you are doing. Put it this way: flashing the downgraded kernel will not screw you up, but doing things the wrong way might.
1. Download this. It's NOT a flashable zip! Just unzip it, and use FTF files to flash the appropriate kernels.
2. Read my post that you linked. It gives you all the steps of the process. Installing recovery is optional, but highly recommended (very useful). Use the kernels you downloaded from my link above.
That's it! A couple of notes...
- I am assuming you know how to use the FlashTool. Not the original one from Sony, but the the one by Androxide. Make sure you are familiar with it before flashing!
- Newroot DOES work with .230 kernel. I have done it many times while playing with different ROM versions, works perfectly. Make sure you enable USB debugging, and watch your phone for prompts to grant access. Your phone should reboot after successful rooting. If for some reason it doesn't work, just try again.
- When you flash .230 kernel, you may have some weird issues with your phone. You will lose WiFi. Your phone may start vibrating for no reason (mine did). Maybe something else, I dunno... Don't worry, it's only temporary. Everything will get back to normal once you flash .292 kernel after rooting. Again, tried and proven fully working many times.
- If you decide to upgrade to LP afterwards, this will also be your procedure to recover, if you screw something up in the process (been there, done that). Just flash your .292 stock ROM, then repeat the rooting process, then start with LP over again.
Happy rooting!
Thanks so much. It is crystal clear now. Always good to get some advice from someone who has done it before on the same phone.
Trying to flash and I got this error (attached pic)
I am running the newest flashtool. I didn't have any problem with the older flashtool in the past when I used to flash my older phones. Also, the older one installed completely in one folder, this one installs in 2 folders, one in C: and the other in C:/users/Me for some reason.
I installed the V1.5 driver package. Not sure what else is wrong. I unzipped the zip file, put the kernel.only.ftf into the firmwares folder, I clicked flash, selected the .ftf file and connected the phone in flashmode. No dice.
Ok, tried it again, this time it didn't get a red error, I got a different one, and my build number is still 10.5.1.A.0292...
Installed recoveries.
Pic is attached.
Okay!
So, after the first flash, the build number didn't change, but the kernel was applied. I just tried using newroot and it worked, superuser is there. Just like you said, the wifi stopped working with the new kernel. I flashed the 0.292 kernel and the wifi came back, and the phone is still rooted.
Thanks for you help kt-Froggy!

Hello,
I'm a noob but usually try to fix this kind of issues on my own, looking at the boards, following tutorials, learning, but this time I think I'm not able to find a solution on my own so I'm asking for advice here.
Some time ago I installed cyanogenmod 10.1 on my Note 2 LTE and was happy with it for some month, than last week I tried to upgrade to cm12.1 It worked but there where some issues and bugs, mainly I wasn't able to swap internal/external sd cards.
So I decided to go back to latest available stock rom 4.4.2 from sammobile.
Here is where the problem starts. The stock 4.4.2 resulter in a bootloop, tried cache/dalvik/factory reset, flash again, whipe again.. nothing.
The phone is not able to get past the white label "Samsung Note 2 gt-n7105" screen. It goes black than the white label again and again.
It doesn't even get to the Samsung animated logo.
Ok bottloop, no problem, try to flash again something else.
I tried different Custom roms, different kernels, different flashing methods. I can flash anything with no problem but every time a get a bootloop.
During the various attempts knox fired, but I don't care. I don't know if this could be the cause.
Actually the only firmware that works is the original oldest STOCK 4.1.2, every other stock firmware past that or any custom rom is bootlooping the same way. To fix I only can reinstall stock 4.1.2 with odin.
I really need any advice or hint.
At the moment my goal is to get at least to stock 4.3 but I cant.........
Thanks!
When you first bought your phone, did it come with Knox?

Try to get the latest firmware available via kies ,that worked for me
http://forum.xda-developers.com/showthread.php?t=2088809/[URL]
From what you've described, I think the Stock ROM 4.4.2 from Sammobile contained a bootloader update. So when you flashed this ROM, it updated your bootloader from the non-Knox version to the Knox version.
I am very unfamiliar with the technical details of Knox, but I think the new Knox bootloader is causing your bootloop problem.
However, I don't know why 4.1.2 works when everything else doesn't work!
Can you check the Stock ROM 4.4.2, and see whether it really contains a bootloader update?

Since a boot.img is present, it means that it would flash your boot partition. So now we know for sure that when you attempted to flash the Stock ROM 4.4.2, your bootloader was changed to the Knox version.
So the lesson here is: before you flash anything via ODIN, always check to see if there is a bootloader update. Usually you don't want to be changing the bootloader on your phone.
***
So now there are 2 possible ways to reach your goal:
1) Keep your new bootloader and see whether you can get Stock 4.3 or Stock 4.4.2 running on your phone
2) Try to restore your old bootloader
As I said earlier, I'm not familiar with the technical details of Knox, so I'm not sure how to get Stock 4.3 or Stock 4.4.2 running on your phone when your Knox indicator is already 0x1. You need someone else to help you.
And you can only restore your old bootloader if you happen to have made a copy of your boot partition before you flashed the Stock ROM 4.4.2. Even if you did have a copy of your original boot partition, I'm not confident with helping you to restore your old bootloader. You need someone else to help you in this case too.
Conclusion: I don't think I can help you to solve your problem I'm sorry. Hopefully someone else who is more of a pro than me will come along to help you out.
Good luck!
I watched a few videos on YouTube on how to upgrade the Android O/S but none of them mentioned that it needs to unlock the bootloader 1st.
So before I found out that I need to unlock it I tried installing ROM before I knew that.
The phone came with Android Kitkat 4.4.2 and there is an official Lollipop for it that I want to install.
The device is rooted with Kingroot.
I tried the installations two times and the phone still works but I can no longer boot into recovery mode or fastboot mode. It just hangs and then I need to remove the battery to get it to work again.
I just want to restore it back to what it was before and then I will work on unlocking the bootloader.
I prefer to use tools that are free of cost.
Issue has been resolved.
I flashed the device with a pac file using SPD upgrade tool and now all is back to default.
