[Q] 5.0.1 Rooted to 5.0.2 Without Data Loss

For some reason I'm just not able to Google this answer or find it here on XDA.
I'm on 5.0.1 (LRX22C) and want to go to 5.0.2 (LRX22G). I have downloaded an OTA update capture and tried to adb sideload it.
It failed. After a sec I thought, "duh. I'm rooted with franco kernel installed." I then did the following:
* Used SuperSU to unroot
* Booted to bootloader
* Flashed stock recovery and kernel
* Rebooted to recovery
* Attempted adb sideload again
This still gave a failure message.
The only other post I've seen where anyone is attempting the same suggests to use Nexus Root Tookit. I'm running Xubuntu. I've loaded it through wine but all the files it downloads are failing hash checks (though the app).
Can anyone post how to go from rooted 5.0.1 to 5.0.2 (LRX22G from LRX22C) without loosing user land data? I'd really do not want to flash the recovery image.
Notes: When trying to sideload with latest CWM recovery the script says that I'm on 4.0.4 (I think) and with TWRP it says I'm on 4.3. With stock recovery it gives me an error about the recovery script (7) or something similar.
Thanks,
Mike G.

Make sure you have downloaded the proper OTA for Nexus 7(2013).
Hashcheck fails in Nexus Root Toolkit is common.After Hashfails,there will be a dialog box which contains the steps to do it manually with the Link to the files.Download it & follow the instruction.
I hope this helps

I'm having the exact same problem. I'm attaching what's appearing on TWRP.

All you need to do is flash the boot and system.img
Then flash su from twrp. It's that easy. No data loss.

I just used wugfresh's toolbox to do it. A piece of cake. I enjoyed a cup of coffee while I watched being updated.

You can also use TWRP and dirty flash the stock, rooted rom by Scrolser found here: http://forum.xda-developers.com/nex.../rom-factory-stock-rooted-rom-lrx22g-t3004110 . Simple and fast with no data loss.

So I can just ”fastboot flash system system.img" from the 5.0.2 image and not loose data?
That seems like it would be the easiest. I prefer the adb/fastboot commands as NRT hides what it is doing and I like to know what's going on when I "do something" liken push a button.

^Yes. It's a good idea to flash boot as well just to get in the habit of it, it didn't change this time I don't think but I could later. Only flash the bootloader if it's a new version no need otherwise.
I simply ran:
fastboot flash system system.img
fastboot flash boot boot.img
fastboot format cache
Done, flash su through twrp to get root back.
You probably don't need to format cache but theres no reason not to and it could save you some trouble.

NRT opens a terminal window (a real-time log) and tells you exactly what it's doing while it does its work.

I have a n7 2013 I have already rooted and installed twrp and SuperSU. I'm currently running 4.4.2 and to update to 5.02. Currently I'm getting the ota update msg for 4.4.3 which I've continued to ignore. With google not messaging me to update to 5.02 makes me think it's required to go to 4.4.3,4.4.4,5,5.02 is that correct? Or can one jump directly to 5.02? I want to keep root and twrp and my existing data I see mentioning of restoring stock recovery first. Why would one do that? What's the point of installing a custom recovery in the first place?
Long time ago I read that ota will work when rooted, but you'll lose root which then can be restored with twrp without losing data. Is that no longer true? Or is it only true of KitKat but not lollipop?

Can't get into Recovery and getting "Security Error" on boot.

I was running Lam Hoang 2.2 just fine on my D850 and then decided to update TWRP from 2.8.6.1 to 2.8.7.0 (released yesterday). I downloaded the right one. I couldn't get it to flash (using the TWRP app or Flashify) and it kept giving me the secure boot error message at the top left of the screen when trying to go back into recovery (it was booting fine, though).
From the TWRP thread, the app creator posted their app AutoRec (https://play.google.com/store/apps/details?id=b007.autorecd850) and I downloaded it, installed, and ran. It worked. I updated TWRP from within recovery and rebooted...and now I'm in trouble
I can't get into recovery (getting the secure boot error message again) and the phone won't boot normally anymore. I'm getting the LG logo with the words "Security Error" in bold beneath the logo: http://k36.kn3.net/ED11C35D9.png
Thoughts? Did I just brick my phone?

I ran into the same issue when i tried to flash the .img file through TWRP.
If you manage to boot your phone normally the you can use the imageprep method to bump the new TWRP version and flash it using the imagepregui. I managed to get 2.8.7 working using this method.

Same Problem "Secure Error"
So my friend I did the same thing as you did and I got stuck and now I cannot use my phone but I may need to go back to stock and then root and get back to AOSP.
I am thinking of maybe there is a recovery.img in the .TOT file and a Boot.img to flash and we may have our phones back in no time, Just maybe.

Very possible, but only if you have access to a method you can flash using (such as if you had removed laf and have fastboot)
I believe imageprep makes a backup of your previous files and stores them on your computer even.
But if you can't get into fastboot then you may have to do a factory kdz image

I am thinking of flashing the files with LG Flash Tool and maybe it will work as i will be extracting the Kitkat TOT file and restore to stock but only flashing the recovery and boot image.

It's possible, I can never get the dang flash tool to see my phone so I can't offer much guidance on that.

I'm thinking the TWRP folks uploaded a non-BUMP'd recovery image to their website...because now 2.8.7.0 is missing from their site and it was definitely there yesterday when I downloaded it: https://dl.twrp.me/d850/. Maybe they never BUMP their images?
I posted in the TWRP thread when it first happened and @bender_007 (maker of AutoRec) reminded me about restoring to stock via download mode and helped me get it back to stock. When I flashed TWRP last night after doing the stock KK > root > install recovery > upgrade to LP process, I used TWRP from @777jon's thread: https://www.androidfilehost.com/?w=files&flid=22377
So yeah, if you're like me and tried updating TWRP using the image from the TWRP site and borked your phone, I'm betting the only way to unbork it is to restore KK stock via the TOT.

Confirmed, it wasn't bumped(while the 2.8.6.0 was)

LG Mobile Support Tool won't download software.

I'm having problems with the LG Mobile Support Tool. When I try "Upgrade recovery" it gets stuck at "Downloading software..."
It starts downloading fast, but after it gets about 30% or so, the download speed drops to nil. My internet is stable and fast. According to NetBalancer, the LG tool starts downloading at a steady 3mb/s, and then drops to short bursts of 50-150kb/sec. I'm not having any connectivity issues with other programs.
I let it keep going earlier today for almost 4 hours. It got to about 60% and then the tool crashed.
There's been a couple of times it said something like "Please check your internet connection, then press retry." The internet connection is fine, and clicking retry will bring it back up to full speed for a few minutes before it slows again.
What can I do?

What version of Windows are you using?
---------- Post added at 04:16 PM ---------- Previous post was at 04:09 PM ----------
Please don't post about the same problems in two different threads. I'm guessing since you using Volume Up to get into Download mode that you have a VK810 variant of the G Pad 8.3, correct?
If so, try one of the KDZs in my signature for the VK810.4G with LG Flash Tool 2014 (Google for it on XDA). That way you don't have to have a tool re-download the KDZ every time you attempt to recover.
If you want root and custom recovery, it's easiest to get both with the 11A KDZ, then flash my ROM in my signature with the latest TWRP v2.8.7.0. If you just want the latest stock unrooted, download the 36B KDZ.
If you don't have the VK810.4G, don't use the KDZs I link to.

I wasn't sure if this should be considered a new problem, or a continuation of the other. But, I can see how that would split people's attention. My bad.
I will try your steps, and let you know how it goes.

Ok, I succesfully got TWRP and 4.2.2 w/root.
Now I have another problem...
When I flash ViKtory Rom and SuperSU, it will not boot. It just gets stuck at the red Verizon screen.
You mentioned that in your ViKtory rom thread:
5.2.2. One user has verified that on their VK810, that once they flash any version of SuperSU.zip that they've tried, including 2.46 and 2.48 beta, the ROM will not boot. You're ONLY recourse is to get into Download mode and use "LG Flash Tool 2014" to Flash the 35A_08 KDZ, and root it using @Hnk1's thread [VK810][ROOT][Lollipop][5.02] No downgrade required.
Click to expand...
Click to collapse
After flashing, I lose the custom recovery and it boots to 5.0.2 without root. None of the root methods in Hnk1's thread succeeded in rooting...
I did this successfully about 6 months ago, so I know it's possible.
EDIT: I just realized that you said to flash the 35A KDZ, and I used the 36B KDZ. I'll download the 35A one and see if I have better luck rooting then.

Re: 35A versus 36B, I just haven't updated the OP. Actually these days I recommend the 11A KDZ because:
1. 11A through 24B can be rooted easily with the Stump app in brute force mode.
2. 11A is 4.2.2, so the aboot (bootloader) doesn't need downgraded prior to installing the initial Loki'd TWRP v2.7.0.1.
Did you upgrade to TWRP v2.8.7.0 before flashing the ROM and SuperSU.zip? Flashing KDZs always returns your device to complete unrooted stock just like from the factory. You should always use "CSE" mode of LG Flash Tool 2014. "Normal" mode doesn't wipe Data or Internal Storage, but especially if downgrading, you can expect that to cause problems.
35A is just as hard to root as 36B. I wrote that tip in the OP after I thought @Hnk1 's method was more easily reproducible. Sorry for the runaround and out of date directions, but you should go with the 11A KDZ.
If you had upgraded TWRP to v2.8.7.0 before flashing my ROM and SuperSU.zip and still had problems booting, you can try wiping Cache and Dalvik again (after flashing), but I don't expect that to work. You can also use CWM Recovery (just flash CWM from TWRP). There's a thread for VK810 CWM on here plus I think I have it in my VK810 section on Android File Host as a mirror, and wipe and flash everything from there. Like I said, that's only if you tried flashing from the latest TWRP v2.8.7.0 (available in these sections) for the VK810 and still had this problem. If you do switch to CWM, you can switch back after flashing the ROM for backups and such.
Good luck!

Success!
Success! :laugh: I am now running ViKtory rom! It's debloated and rooted and sweet! Thank you so much for your help. I believe this is the 2nd time you've saved my tablet!
One last question: Do I need to flash aboot to access recovery with your rom?
Here's all the steps I took on my path to success, just in case anybody finds it helpful.
===============================================================================
To return to stock, unbrick, or prepare to root.
===============================================================================
1: Open LG Flash Tool 2014
2: Use the following settings:
- Select Type: CDMA
- PhoneMode: DIAG
- Reset time: 33000
- Select KDZ file: Use newest to go back to stock unrooted
Use 11A if planning to root/twrp
- Upgrade with CSMG Client: Normal Flash will not wipe, SCE Flash will wipe
3: LG Flash Tool will open LG Mobile Update tool. If an error window pops up
saying "Cannot connect to server..." Ignore it. DO NOT CLICK OK! It will run
it's course and the tablet will reboot.
4: Done with that.
===============================================================================
To root
===============================================================================
Use Stump Root app. (Bruteforce)
===============================================================================
To install TWRP custom recovery
===============================================================================
1: Connect tablet in debugging mode.
2: Navigate to where loki_flash and twrp.lok is.
3: Open cmd from this location.
4: Run the following commands:
4a: adb push loki_flash /data/local/tmp/loki_flash
4b: adb push twrp.lok /data/local/tmp/twrp.lok
4c: adb shell
4d: su
4e: cd /data/local/tmp/
4f: chmod 777 loki_flash
4g: ./loki_flash recovery /data/local/tmp/twrp.lok
4h: exit
4i: exit
4j: adb reboot recovery
The tablet should now boot to TWRP
===============================================================================
To install ViKtory rom
===============================================================================
1: Boot to TWRP recovery v2.8.7.0
2: wipe system, data, cache, dalvik and internal storage DO NOT REBOOT
3: Go to Mount > enable MTP
4: Copy ViKtory rom and SuperSU zip files to tablet (and debloat scripts if
desired.)
5: Install zip files (may have to switch between IMG and ZIP to see them.)
6: Reboot.
ALL DONE!

Great! You're welcome, I like hearing about successful device adventures.
Yes, the exact directions what I have at the bottom of the first post. I'm unfortunately not knowledgeable enough to solve the boot into TWRP problem with the Lollipop bootloader / getting Lollipop to boot without he Lollipop bootloader on the VK810, although @xdabbeb gave me some ideas to try if I ever find the time.

LG Support tool get stuck at 60% installing new firmware/KDZ files to reset LG ms323 phone to factory settings.
What is the solution to this problem?

Urgent Help: Can't Upgrade or can't Go into recovery mode

Hi. I have a weird issue. I have a D855 phone which is running on kitkat v10n. I thought of Upgrading it to official 5.0 or 6.0 firmware and decided to check for the option software update in my phone. But I didn't find any. So i thought of installing TWRP recovery to my phone. and I flashed through flashify and cant boot into recovery menu but i can see fastboot menu started and some other 2,3 lines at the top left corner of the phone. I cant even reset the phone also as doing that going into same fastboot menu but when i pull the battery and place it it is booting.
The real thing starts from here. I want to check whats wrong with my phone and found that actually my phone motherboard is LS990.Not D855. So I came to know that as i wrong flashed the recovery, I am getting fastboot mode. So can I flash tot file directly now or not? if doing so will it result in hard/soft brick or in boot loop? Please help me to upgrade from kitkat to lollipop without any damage to my phone. Expecting a resolution from you. Thank u..

Can you still boot into download mode or not?

You did not see the upgrade because either your sd card is full or too small for update to fit. Happened to me once. When you sort this up, make some room on your sd card and then let the OTA do the thing.

If you can boot into download, it would be possible to flash kdz. Just you must find the right one for your phone!!
Edit: you will have to use LG flash tool. LGUP is only for D855.

no.for ls990 there is no kdz i think so.only tot and dll files.but i am doubtful in flashing anything before fixing the fastboot menu as i could brick my device if anything wrong happens..

Ufff.
This is the hard way but at least first you check your memory for errors, and somewhere in the text it clearly says that fastboot is a no-go.

I personally would go with a download mode and tot files, AND DISBLED ALL THE THINGS THAT WANT TO KILL PROCESSES. like antiviruses, win-defender etc.
Trust me, I know how you feel, maybe some more ideas drop into the thread.

So lets explain few things first. You can safely flash tot files via download mode. Tot file contains your stock recovery partition as well. So everything will be flashed to stock. So if you find tot file to flash for your model fell free to flash it.
Instead what I would suggest is for you to flash TWRP, and after that flashing Lollipop zip with TWRP.
Here is how:
You download TWRP zip for LS990 from here if you are sure that's your model:
https://www.androidfilehost.com/?fid=24052804347763136
then you extract recovery.img file from the zip,
then to flash it either use flashify or these adb commands:
adb shell
su
dd if=/dev/zero of=/dev/block/platform/msm_sdcc.1/by-name/recovery
dd if=/sdcard/recovery.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
Ofc if you use these exact adb commands you need to place recovery.img to root of your /sdcard.
So now you confirm that you have a working TWRP. Try to boot into it.
If it succeeds you have Sprint Lollipop files provided here:
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVA
You only need these files: system.img, boot.img, modem.img, rpm.img, tz.img
IMPORTANT: boot.img you download from here not from the link above:
http://forum.xda-developers.com/attachment.php?attachmentid=3165683&d=1423941988
After downloading them and placing them in root of sdcard, boot to TWRP open terminal and write these:
dd if=/sdcard/system.img of=/dev/block/platform/msm_sdcc.1/by-name/system
dd if=/sdcard/zv8_boot_fixed.img of=/dev/block/platform/msm_sdcc.1/by-name/boot
dd if=/sdcard/modem.img of=/dev/block/platform/msm_sdcc.1/by-name/modem
dd if=/sdcard/rpm.img of=/dev/block/platform/msm_sdcc.1/by-name/rpm
dd if=/sdcard/tz.img of=/dev/block/platform/msm_sdcc.1/by-name/tz
That's it.
Credit for these files goes to the OP of this thread @autoprime

I assumed that system.img was provided in links above. It isn't.
So here:
http://downloads.codefi.re/autoprime/LG/LG_G3/LS990/stock_partitions/ZVB/
Download zips only. Flash them, no need to use dd command. It is prerooted Lollipop. Again credits to @autoprime.
And perhaps if you would like to check Marsmallow here's a thread:

Thanks a lot. I checked the marshmallow post. i found that it has some issues. Am i right?? Data is no working and some call issues also. Is there any other Marshmallow stock feel rom??
so as you said to flash, flashing system.zip and modem .zip is enough?? What about boot.img,tz.img and rpm.img?

I would wait for MM to settle a bit, some guys have icons problem, some LTE, some stuff is downgraded to work properly. How ever you go, you will not get clean MM. Only if you do not want root, and that is a no-no for me.

You checked Marsmallow post, that's how it is. I have d855 so I have official Marsmallow, cant tell you about that port. You can always test it if you wish then revert back.
Yes flash zips only. All those partitions are provided in them (LG-LS990ZVB-Flashable.Modem.RPM.TZ.zip; LG-LS990ZVB-Flashable.System.Boot.zip).

I flashed it but after booting android process is force closing for every 5 seconds and its showing the same message. So I went into recovery menu, wiped dalvik cache and cache,data and system and made a factory reset again and rebooted it. But my phone stuck on LG logo only. Now i can't even enter into TWRP Recovery . What to do?? Flashing tot is only the solution? I can go into download mode..
Edit: I tried going to TWRP manually. First I tried by going to recovery mode by watching a video showing holding volume down+power button and release after the LG logo is seen and within half second again should hold back. That didn't work for me. I only holded volume down+power button untill I see "Recovery mode loading" screen and after 2 seconds it taken me to TWRP. I successfully re-flashed back the zip files again. Thanks for your help. but i am getting invalid sim and showing hands free activation on my phone.. So should I need to unlock it?? now big trouble with the sim problem.Can u provide any solution??
Edit 2: Even this I solved myself.. thanks a lot.Hitting thanks button

Troublesome. I have no knowledge what "hands free activation" is. I belive it's something connected with Sprint?
As for the invalid SIM, was your phone SIM locked? Where did you buy it and why did it even have d855 system flashed onto it if its ls990?
Can you make calls and have you made a backup of your old system in TWRP before flashing?

I followed one link and replaced some files and got the signal back. But I am unable to access data in my phone. also in settings i am seeing activate this device. I disabled hands free activation thing which is very annoying. But flashing any other lollipop rom, can I use data in my phone? Can you suggest any best lollipop rom like cloudy or other than cloudy?

Installed twrp, but can't get into it

I did the following
1. Downgraded to V30b-EUR-XXX with LGUP. Went smooth.
2. Rooted phone sucessfully with kingroot.
3. Got a shell with "adb shell"
4. "su"
5. Filled the recovery-partition with zeros from /dev/zero with dd
6. Installed twrp3.2.3-0 with dd on recovery-partition
When I boot into Marshmallow, all is fine. When I boot into recovery, I'm informed about a necessary factory reset. I say "Yes" both times, then the LG Logo and some tiny text is displayed and afterwards the screen goes dark. The LED is blinking blue and red; the only way out of this is to remove the battery.
If I do a factory reset from within marshmallow, the result is the same.
What can I do now? Should I flash a stock recovery with dd? But where to get it? Or should I flash an older version of twrp?

Hello,
Last time when I downgraded, I also rooted with KingRoot, but I installed the "Flashify" full version, ( on the ROM of course ) and I flashed the twrp with the flashify as "recovery". This is working.

Excuse me, but I'm not able to decipher that. What is flashify? What means "on the ROM of course"? Can you give more information please.

- flashify is an application.
- on the ROM = when the phone booted and the operation system is working, you can use your phone... example for phone calls. As you wrote: "boot into Marshmallow"
So, downgrade again, and boot into Marshmallow, use the kingroot, than install the flashify application. You can flash the twrp with the mentioned Flashify application, than reboot to recovery.

Don't had to downgrade, because I was in V30b. Got root, installed flashify and flashed twrp - the first time 3.2.3, then 2.8.0. Same result as before.
From what version of android did you install what version of twrp?

Hi,
I use the twrp3.2.3 and no problem.
I'm not expert, I just can recommend some steps...
Maybe good idea to flash again the stock ROM. You can find here on the forum many step by step guide for this. ( tools and steps )
It seems your phone recovery partition is not OK....
I have no more idea...

@theuving, why did you decide to zero out the recovery partition? I don't know but that may be part of the problem. Since you were connected via adb was it not possible to use fastboot? Flashing the recovery via that should(?) have also worked.
If the recovery partition is messed up you might have to start over. Not sure though as I haven't experienced that problem.
ZTE Axon 7 A2017U, /e/ v0.1 ROM, microG (NoGapps), Multiboot, XDA Legacy

It's the same partition where I flashed twrp, so the zeros are already overwritten with something else ...
Seriously: Zeroing the partition before writing to it was mentioned in a thread about the installation of a "bumped" recovery.

OK, that is the version I used also. What android version was installed when you flashed the recovery? Mine is stock V30b.

Hi,
I'm not sure, because I changed to 8.1 (oreo).
Maybe V30N.....

I am having the same problem. There is no "unlock bootloader" in the developer options, and adb reboot bootloader just starts into android again. I might have to reflash the stock firmware, but nowhere in the install instructions for twrp does it say that you first have to unlock the bootloader, and nowhere does it even mention that there might not be such an option. This is genuinely strange.
