[V500] How to install TWRP under stock LP? - G Pad 8.3 Q&A, Help & Troubleshooting

I recently flashed the korean LP build on my V500. Since its terribly slow I wanted to move to CM. I read that TWRP is required to flash it and hence tried installing TWRP using both the TWRP Manager APP and flashify but neither of them seems to work as they are meant to work only over KK bootlaoader. Is there a ways to install TWRP over LP bootloader?

You need to install kitkat bootloader first and then install twrp (root is required):
1) Download kitkat bootloader: https://www.androidfilehost.com/?fid=24352994023707804
2) Extract the 6 bootloader img files and copy them to the internal sdcard.
3) Install Terminal Emulator and open it.
4) Run the following commands (grant root access to Terminal Emulator after the first command):
Code:
su
dd if=/sdcard/aboot.img of=/dev/block/platform/msm_sdcc.1/by-name/aboot
dd if=/sdcard/rpm.img of=/dev/block/platform/msm_sdcc.1/by-name/rpm
dd if=/sdcard/sbl1.img of=/dev/block/platform/msm_sdcc.1/by-name/sbl1
dd if=/sdcard/sbl2.img of=/dev/block/platform/msm_sdcc.1/by-name/sbl2
dd if=/sdcard/sbl3.img of=/dev/block/platform/msm_sdcc.1/by-name/sbl3
dd if=/sdcard/tz.img of=/dev/block/platform/msm_sdcc.1/by-name/tz
5) Download latest official TWRP, rename it to twrp.img and copy it to the internal sdcard.
6) Open Terminal Emulator and run the following commands (needs root again):
Code:
su
dd if=/sdcard/twrp.img of=/dev/block/platform/msm_sdcc.1/by-name/recovery
7) You are done! Reboot to recovery and flash any rom you want.

Wohooo it woked! Finished flashing you unofficial CM build. Thanks and keep rocking!

Hpw do you root stock lp v500?

that's exactly what i was thinking. what did you do ravi?

Same question here... On. Stock lollipop Korean version but assume I need to be rooted to try the steps detailed above?

If you don't have access to a custom recovery, I guess you could root using this method (I didn't test it), you will also need LG drivers.

thank you for the guide I could boot into recovery but after I rebooted normally (i didn't do anything in TWRP) I got a boot error cause: boot certification verify. will installing cm12.1 solve the problem despite that flashing roms won't flash boot partition? or I should go to download mode and install stock rom? i still can boot to TWRP but not the rom

Where exactly shall I copy the img files to?
Have tried to copy them to the following places:
/
/sdcard/
/data/media/
/data/media/0
Also tried to use sd-card in command instead of sdcard, but I always get the same error; No such file or directory
Any suggestions?

Finally got it to work.
For some unknown reason Terminal Emulator would not accept the location for the files when I placed them under /sdcard/
Moved the *.img files to /storage/emulated/0, and used this location in the commandos instead of /sdcard/

Sorry for kind of off topic but I recently had the same reboot experience on the VK810.4G. It normally works and works again now. It works now too and was doing lots of unrelated things to my tablet so no idea what caused or fixed the issue.

Hi
thanks for the details,but after flashing TWRP I cannot boot into the system anymore:
"Secure booting Error!"
Cause : boot certification verify"
I can still boot into TWRP,but there seems to be something wrong with the Kitkat-Boolader...
Is there a another way to install TWRP from 5.02 or do I have to go back to Stock 4.2 with the LG-Tool ?
cheers

You can put these files onto microSDcard and use the same commands just like flashing KitKat bootloader.

Hey! Thanks for the tip! Just to clarify: when you flash the LP bootloader do you lose access to TWRP?
In the Stock installs of LP (HK or Korean) I've tried the LP bootloader appears to be "locked" (can't think of the right term) so that you can't access stock recovery from key strokes. Can you still keystroke boot into TWRP?
Many thanks!

Deleted, never mind.

How to install Clock Work Mod on a100 with unlocked boot loader !

DISCLAIMER
Thank you to all the DEV'S who have made this possible BIG UPS TO YOU
This worked for me, and in theory if my instructions are followed carefully it will work for you.
However if your results are not the same I am in no way responsible for any dammage done to your tablet!
THE GOOD STUFF
This was tested on Acer A100 on the latest ICS LEAK found here http://forum.xda-developers.com/showthread.php?t=1510706
Also my PC is running windows 7 x64
(Follow install instructions carefully)
First install the latest ICS leak http://vache-android.com/v1/index.ph...files&file=148
Once complete do a factory data reset on your device from the settings/backup and restore menu on the tablet
When that is complete, Root your Device using the method found here http://forum.xda-developers.com/showthread.php?t=1531646
( again Follow instructions Carefully )
BE ABSOLUTELY SURE YOUR DEVICE IS ROOTED BEFORE YOU GO ANY FURTHER!!
Unlock your BOOTLOADER using the method here http://forum.xda-developers.com/showthread.php?t=1557445
(Really be careful here!)
This is where it gets tricky download http://forum.tegraowners.com/viewtopic.php?f=7&t=369 for your OS and extract recovery_thor17_403.img to the root of your platform-tools folder for instance mine is C:\android-sdk\platform-tools
Once completed on your PC open a command prompt as an administrator and navigate to your platform-tools folder from cmd prompt e.g. cd c:\android-sdk\platform-tools and hit enter
next type the following commands:
adb reboot bootloader
once in bootloader mode type:
fastboot flash recovery recovery_thor17_403.img
and hit enter you will see it flash to your device within a couple of seconds.
once complete with the tablet in upright landscape mode ( home button on the right hand side ) power the device down and power it back on while holding the leftmost volume button firmly when it vibrates you may release the power button.
continue to hold the volume button until you see Booting recovery kernel image on the screen.
if all went well you now have cwm on your device
now for rom manager!
boot back into android OS and navigate to the google market, search for rom manager in the upper search pane.
download the app and install
open the app and press ok
next press flask clockworkmod recovery
next confirm your phone model
a popup will say your device is not officially supported press yes
next confirm version 3.x+
and you should be good to go

First check out this post http://www.acertabletforum.com/foru...rkmod-recovery-your-acer-iconia-tab-a200.html
Download the updated file from the above website, extract it to your desktop, and run acera200simpletool.bat and follow the onscreen instructions.
Once complete download the rom manager app from the market and install it.
Once installed open from manager and choose flash clockwork mod recovery from the top of the list, then confirm your device is Acer a100. It will say there is currently no recovery for your device and ask if you installed a custom one, choose yes and select the second option it should say 3.x.x or something to that effect. Again confirm your selection and tada you now have cwm and a working from manager. I have tested this and made a complete backup already. Cheers

hello masterpcker...Did you install anything else first? Were you just using the standard a100 root? Also, did you unlock your bootloader beforehand? thanks so much friend
Yes I unlocked my boot loader first, and my device was rooted so all I did was run the .bat file from the above website and choose option 3 install recovery only. I am about to try a modded a500 from and see what it does.

I will be eager to hear how that comes out! I wish you the best of luck, but I'm not real confident. let us know the outcome if you don't mind....good luck!
For some reason I followed the directions to install CWM and it doesn't work.
When I try to boot to recovery all I see is the android mascot on it's back with a warning sign. If I press the home button it brings up the Android System Recovery, which I believe is the stock recovery. I'm not even sure how to select the items. I can only highlight the menu items using the volume keys.
It doesn't look like the cwm that I have flashed on my atrix.
Any ideas?
Edit...
Btw, I did unlock my bootloader
Well the a500 modded rom was a bust, it just booted to a really colorful screen lol. But my Android backup worked great for reinstall

What's the syntax did you use to dd to the device?
I found this dd syntax in the other thread. That the same one you used?
Code:
su
dd if=/mnt/external_sd/recovery.img of=/dev/block/mmcblk0p1
-Extract the zip folder "recoverycwma100" ( It's a recovery into Acer a200 simple tool )
-Copy ''recovery.img'' into your external sd card
-open a terminal emulator to your A100 ( root acces !!! )
- Write the following commands :
su
dd if = / mnt / external_sd / recovery.img of = / dev/block/mmcblk0p1
-wait a message '' xxxx bytes transferred in... ''
-exit terminal
-open root explorer with a mount system
-rename the file '' install-recovery.sh'' into /etc/ it '' install-recovery.bak''
Reboot into recovery with volum down + power , and Enjoy

Can't we just go into fastboot and use fastboot flash recovery recovery.img?
If you're running linux or just want to use adb it's way more simple than it looks.
Code:
Adb reboot-bootloader
fastboot flash recovery recovery.img
fastboot reboot
And if you brick your device by accidently installing the wrong boot.img
find your respected rom .zip file that you are currently using and use this.
Code:
Adb reboot-bootloader
fastboot flash boot boot.img
fastboot reboot

I can confirm that I have already flashed the recovery.img via fastboot, however cwm still fails on my particular tab. I did a full factory reset and flashed the entire new ics through recovery with the exact same results. I will be investigating the cause of some tabs doing this later tonight when I get home from work. If someone figures this out please post. I have gotten the recovery.img to flash via the a200cwm, however android exclamation upon recovery attempt. i have tried all three paths with no success. I am almost certain that it is a problem with the rooting method, but i won't have time to have a look until tonight. thanks and goodluck! I think the problem could be because of installing different rooting methods in the past, however I have yet to find a way to solve it.

Many thanks on this! After two plus years from this post I was struggling with the same trying to flash CWM 6 over TWRP. This one helped.
I did it through TWRP's terminal (Advanced / Terminal Command), and after choosing folder where the img is, typing the command you gave.

Follow these steps exactly and you will have the latest Recovery running. You do not need a PC for this method.
1) Download correct Clockworkmod ot TWRP (touch or regular as you wish) for your device
2) Rename it to recovery.IMG and place it at the root of your internal sdcard
3) Download and install terminal emulator from the Play Store
4) Run the terminal and
type: su (press enter)
Then type: dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18 (press enter)
Be sure that you have typed the above code correctly. You will not see a confirmation. It is done almost instantly.
5) Reboot into recovery and enjoy
I don't remember the commands, had to do it about 3 years ago, but you can do it from terminal emulator. A Google search should give the results you need.
I don't use cwm prefer twrp which can be done from the goomanger app I believe it can be done from rom manager though.

I considered TWRP, but was scared to change out of fear something would go wrong... I think I will probably go that route. thanks!
EDIT: Tried to use Goo.mgr to install TWRP. It downloaded and went through the process, but recovery still loads CWM.
Found this on TWPR's website:
Paul Ireland • 11 months ago
So, I had a question. I couldn't really find any guides on how to install this if you already have CWM. I tried using goomanager to install and it would go through and say everything had completed, but when I'd reboot into recovery, I'd still have CWM.
My response, was to .tar the recovery image and install via ODIN.
Everything seems to have installed OK, I successfully flashed a ROM with it, but are there any drawbacks (other than the flash counter) to this method?

Does your USB port work? If it does, you can flash TWRP via Odin.
My odin doesn't flashes it.
I did all the steps that we should do to flash a recovery but when it completes my device stucks at the boot logo and then again i have to flash my stock recovery to get it back running.
Which recovery are you flashing? This is TWRP for the d2lte: https://dl.twrp.me/d2att/
Download the latest tar version of TWRP, open Odin, uncheck everything except f.reset time, flash, when you see reset" in the status window, remove USB cable, remove battery, replace battery, boot directly into recovery mode.
Not working
Thanks for the suggestion but i did all the same steps but not working i download TWRP officially but when I flash it with odin it stucks at the boot and then I have to flash the stock recovery to get it back running.
Just to confirm but the phone being flashed is an i747?
Why not buy a new usb cable?
Will this method of the Android Emulator will work for every other Android Phone or just for Samsung ?

The shell command referenced in the OP dd if=/sdcard/recovery.img of=/dev/block/mmcblk0p18 is highly device specific. You would need to make sure you use the right command for your device, as you are specifying the recovery partition with /dev/block/mmcblk0p18. Having said that, newer devices which use the A/B partition scheme don't have a recovery partition, so this entire thread is not applicable.

ZE500CL Can't boot TWRP/Recovery, Can't factory reset

Picked one of the 2e's up cheap. Check your Walmarts, it's on clearance for $11.
Followed the Root instructions. No problem there.
Followed the bootloader unlock instructions. It seemed to work but my splash screen didn't change.
Went to install the Russianbear Rom. That left me with a blackscreen and nothing else.
From there, I managed to get into TWRP and flash the Stock ASUS ZE500CL Rom. That went in fine and the phone is 100% functional.
But now, I can't boot into recovery or even access TWRP. If I Power+Vol +, to where it gives the option of Recovery/Reboot/Power etc, Recovery just brings me back to the same menu. I reflashed TWRP on through ADB. Still no go.
I rerooted and installed TWRP manager to attempt to reflash just brings me back to that same menu.
I wanted to reset it to stock again with the ZE500CL rom, or if possible, test a different rom for ****s and giggles. Just to see what flavors are out there.
Any input into how to get TWRP or another flasher working would be appreciated.
Fastboot flash twrp. I've had issues with twrp manager on that phone

I did. Fastboot Flash Recovery Twrp.img through CMD. Still nada.
It's the first TWRP I used. and the crap thing is, I can't even revert to stock because that involves going through a recovery.

Try adb reboot recovery in Android. Remember to turn on USB debugging

done that too. Nada. And yup, still in Debug mode.
I take this from a Vietnamese post, you should read the post to see the screenshots: http://amtech.vn/threads/tat-tan-tat-ve-recovery-tren-zenfone-2-ze551ml-ze550ml.365204/ (these are different methods, not steps in one method)
Translated:
I. If your are unlocked and rooted, download Terminal Emulator from Play Store, copy your TWRP image to /sdcard, rename to recovery.img, then open Terminal Emulator, type
Code:
su
dd if=/sdcard/recovery.img of=/dev/block/by-name/recovery
Remember to grant access to Terminal Emulator after typing su.
II. Download Rashr from Play Store (must be rooted and unlocked)
Copy your TWRP image to your sdcard. Open Rashr and choose Recovery from Storage then navigate to your TWRP image. Select YES at the prompt. (grant superuser if prompted)
III. Copy your TWRP image to your SDcard, then boot temporary TWRP, choose Install... then select Image... then choose the image. Select Recovery. Slide to confirm flash.

Help rooting Huawei Watch

Hi,
I'm a noob trying to root my Huawei Watch (to be able to read BTLE messages). I used egalite_kernel_HW_dffc4c0-2.0 which should be rooted (and indeed I see su.sh and busybox.sh script in the /setup folder)
I did the following:
sudo adb reboot bootloader
sudo fastboot reboot-bootloader
# Unzip TWRP_3.1.1.-0_Unofficial-Sturgeon.zip => recovery.img
sudo fastboot boot recovery.img
#In the phone, using TWRP, set to ADB sidleoad (wipe data and wipe cache)
sudo adb sideload negalite_kernel_HW_dffc4c0-2.0.zip
TWRP loaded fine and the rom installed fine to, but when opening the "Advanced Settings" it says that the phone is not rooted.
Any hint of what I did wrong?
Thanks

You keep saying your phone. Are you trying to root a phone or a watch? I'll assume you're talking about your watch.
adb sideload is for applying OTA updates. What you want to do is flash that zip.
While in TWRP, do the following:
sudo adb push [path to kernel zip] /sdcard
In the TWRP menu, select install. Navigate to /sdcard and select the zip. Install it.
If you can't get that working, just flash the supersuwear.zip I've attached to this post using TWRP: https://forum.xda-developers.com/hu...aw-1-5-build-m9e42c-to-downgrade-2-0-t3607859
Also, use the advanced wear settings from the play store. I've had issues with the one that negaman includes in his thread.

Yes! I just want to root the watch.
Thanks, for the reply. I'll try it and report back
I installed TWRP_3.1.1.-0_Unofficial-Sturgeon and then I tried to install negalite_kernel_HW_dffc4c0-2.0.zip
sudo adb push negalite_kernel_HW_dffc4c0-2.0.zip /sdcard
and Installed using TWRP.
Unfortunately I got the error below:
--
set_perm: some changes failed
Updaterrocess ended with ERROR:
Error installing zip failed
--
Trying to fix the problem I started wiping parts and I screw-up and delete the system. Wonderful.
I then tried to find ROMs and finally I found Huawei-Rom-NX-v2.7.zip and successfully installed (with Root)
https://forum.xda-developers.com/hu...-negalite-huawei-rom-nx-root-bb-v1-6-t3406813
Unfortunately I find out I need a specific build NWD1.171016.002 (Stock ROM from December 2017).
Any idea were to find it?
Or shall I open a new thread?

Why do you need that? You're running a rooted rom, right? Wasn't that the goal?
If your goal is actually to be on a rooted rom AND be on the latest system software, I think it would probably be best to start from scratch since you've done so much flashing and I'm really not sure what state your watch is in at this point. This is how you do that:
1. Download this factory image: https://www.androidfilehost.com/?fid=745425885120748838
2. Extract output.tar from that package. If you need software to do this, I recommend 7zip.
3. Extract the contents of output.tar.
4. Copy flash-all.sh, image-sturgeon-m6e69f.zip, flash-all.bat and bootloader-sturgeon-m6e69f.img to the same folder where you have installed fastboot.exe.
5. Boot your watch in bootloader mode (aka fastboot mode), connect it to the computer and double click on flash-all.bat. This will bring your watch to a 100% stock state.
6. Setup the watch and keep taking OTAs until you are on NWD1.171016.002 (there should only be 1 or 2 that you have to take).
7. Boot into bootloader mode and do one of the following steps:
If you want to keep the stock recovery menu and only use TWRP temporarily, perform the command fastboot boot [path to TWRP image].
If you want to have TWRP permanently installed on your watch, replacing the stock recovery menu, perform the command fastboot flash recovery [path to TWRP image]. Then select reboot to recovery in the bootloader menu.
8. Download the supersuwear.zip package that I linked to in my previous post.
9. While in TWRP, adb push [path to supersuwear.zip] /sdcard
10. Install supersuwear.zip using TWRP menu.
And there you go. Latest firmware version, rooted. Download advanced wear settings from the play store if you want it.
Youre the man.
