I noticed that many people still have problems with understanding what bootstack is. I added more information in the first post and also placed some new warnings for less advanced users. I hope this will help them stay "out of trouble".

I recommend for all users to read sections:

- What is BOOTSTACK ?

- Which BOOTSTACK do I need ?

- I still don't understand what is BOOTSTACK for

I think reading them will help understand how all this works. If anyone is still having some questions then ask them.

I also replaced D415 20B zip. The new one should work properly (I hope).

Bootstacks for D405n has been labeled as STABLE thanks to help from users.

Ahh you are using my ROM. Yea you can't flash a lollipop bootstack if you plan on using any custom ROMs. All of our custom ROMs need the kitkat bootstack

[LG Optimus L90] Xemidra:
Thank you for your input.

I can add 20C version but without unlocked bootloader I would have to include one from 20B.

In 20B and 20C there is the same bootloader. So I already created and uploaded 20C bootstack at the request of users.

BOOTSTACK for D415RD version 1.1 created from 10C kdz version was added per request from some users.
[LG Optimus L90] Xemidra:
New BOOTSTACK for D405N added.

BOOTSTACK for D405N version 2.5 based on KDZ 20B for Polish mobile operators was added. It should match FlashableSTOCK 20B for D405N. Bootloader from version A. TWRP in version 2.8.5.0 included.

For more information and download links head over to first page. Backup of you current ROM is recommended. Unlocked bootloader and custom recovery required. This zip will overwritten all partitions placed deep inside your phone which may cause some serious damage to your phone. Please read everything very carefully and take a look at status before applying.

Just to make some things clear.

I'm on stock LP, i have D410, unlocked bootloader and TWRP.

Now, what happens if i just flash Bootstack for KK, can i still normally use LP or i have to flash custom ROM ???

Also when i make recovery backups, do i need to flash Bootstack for every version of ROM that i want to use ( LP and KK ) or will TWRP restore everything to original ???

tnx ...
[LG Optimus L90] Warimation:
If you flash kk bootstack you must flash a custom rom or flash stock kk rom.. Only stock lollipop must have LP bootstack.. All others (including LP custom roms) work with kk bootstack.

And you dont need to flash bootstack when changing roms or making backups..

[LG Optimus L90] Xemidra:
TWRP does not make a backup of your BOOTSTACK.

You only need to change BOOTSTACK when you're going between stock KitKat or customROM and stock Lollipop.
[LG Optimus L90] bacitoto:
Here's my example:

I'm on cm12.1 and want to test stock lollipop

cm12.1 is currently based on KK so I flashed lollipop bootstack before I flashed the L FlashableSTOCK.zip

Everything worked fine

Now that I saw how awful stock lollipop is I wanted to revert back to my cm12.1

But when I tried to revert to cm12.1 or even stock KK I had some problems

I flashed the KK bootstack and flashed the cm12.1 rom, SIM not working, camera app not even showing , installed a third-party camera, didn't work

I flashed the kk flashableSTOCK.zip and still no camera or SIM

I think the kk bootstack might not be correct, or maybe you can't downgrade from the L bootstack

I've solved the problem via the normal KDZ way, I'm running a d405n, props to your work
[LG Optimus L90] 4peace1:
wrong step you followed bro

Here is the step

from kitkat

its either you should flash cm11 then flash cm12.1 or

fLASH cm 12.1 from kitkat direct and FLASH KK BOOTSTACK after not before

from LP

Flash cm 12.1 then flash kk bootstack

Here is simple rule

When coming from Stock rom, flash customised rom first then bootstack

When going back to stock rom flash the bootstack of version(KK or LP) you are going back to then flash the flashable stock rom.

Thanks
[LG Optimus L90] bacitoto:
Ah, so that was it, thx for the clarification, which means this is super useful after all :)

package_extract_file("TWRP_2.8.5.0_120215_L90.img", "/dev/block/platform/msm_sdcc.1/by-name/recovery");

Is this really necessary? I mean, we are already in TWRP, flashing TWRP again? What's the point?

Btw, I managed to unlock D410hn (brazilian dual-sim variant with nfc, NOT the D410) kitkat v10c and lollipop v20b bootloaders, I already tested the lollipop aboot and It worked. I'm building proper bootstacks for the d410hn variant so people stop using the regular D410 files.

---

Success. I Just tested the KitKat and Lollipop D410HN unlocked bootloaders and bootstacks and I could go between stock KitKat 4.4.2, stock Lollipop 5.0.2 and CM12.1 without problems.

Also, I removed the recovery from updater-script, it wasn't necessary, you already have TWRP installed, there is no point on flashing it again.

I kept only the partitions that differs from the two versions of bootstacks, stock kitkat and lollipop system/boot/data are flasheable via the zips in the another topic for those who want to go back to stock, just match the android versions.

I'll upload the files tomorrow (both d410hn unlocked kitkat and lollipop unlocked aboots and bootstacks).
[LG Optimus L90] Xemidra:
I added TWRP in case that someone were using other recovery than TWRP.
[LG Optimus L90] Floating Point:
Just specify in the topic that all the zips must be flashed with TWRP 2.8.7.0. People must have their recovery images updated to make sure everything will work properly.

Flashing TWRP over the already existing version resets some user preferences in settings.

Here's the KitKat and Lollipop bootstacks with unlocked bootloader I built for D410hn (brazilian dual-SIM with NFC). All files were retrieved from the actual KDZ images of D410hn that is sold in Brazil only (including the aboots that were unlocked), and not the regular D410 (foreign dual-SIM without NFC).

Unlocked aboots only (extract file inside the zip):

I tested all files and can confirm they are all working. I didn't include TWRP in the flashable bootstacks, make sure to have the latest TWRP (currently 2.8.7.0).

[LG Optimus L90] sir_dwtc:
I used version 1.2 for the D415 and it's been working great for several weeks now. Camera, data, everything except for recording videos and playing some videos, but I'm pretty sure that's more of a CM issue.
[LG Optimus L90] Xemidra:
You have to contact your ROM developer about those issues. They are not bootstack related.
[LG Optimus L90] Niquel97:
KK version for D405 not working for me. I would need those files for v10_a version not v10_c like those files are.

Im running uberslim LP atm and i got only signal without mobile data (3G)
[LG Optimus L90] sir_dwtc:
Definitely, that's what I was actually trying to say. Sorry, I didn't mean to make it sound like I thought it had anything to do with the bootstack. It's definitely a ROM issue. I shouldn't have mentioned it at all, sorry about that.
[LG Optimus L90] stevedawg85:
So I installed 1.2 KK bootstacks and worked perfectly on my L90 D415 to get the SIM working on my CM mod. However i decided to go back to a stock ROM of lollipop. Is it safe to simply flash the LP bootstacks? Then install a stock ROM?
[LG Optimus L90] mosimchah:
Yes.
[LG Optimus L90] kostikasdrift:
hi! i have a rooted lg90 d405n using ownrom lollipop 5.1.1 and TWRP recovery. after flashing rom baseband and imei became unknown. can i pass some bootstack installation steps or i have to do all from begining.?
[LG Optimus L90] mosimchah:
All you need to do is:

1. Download the KitKat bootstack for your device (this is located in the OP).

2. Boot to TWRP and flash the bootstack

3. Reboot the system.
[LG Optimus L90] Floating Point:
Please update to include a new bootstack for d410hn, there is a new bootstack for D410hn v20c Lollipop, the previous one I provided is compatible with v20a and v20b, but I checked the new build files and there were some changes on the bootstack, if you flash v20c boot/system with v20a/b bootstack, system won't recognize the right build version, and probably can lead to some problems.

D410hn Lollipop v20c bootstack: http://www.mediafire.com/download/wxa5m1ch80hth54/Bootstack_D410hn_Lollipop_v20c.zip

Includes unlocked aboot. Do not flash recovery (again to avoid TWRP setting reset).

My LG Optimus D415 does not recognize a cellular network at All. I have tried all options :

I used KDZ . method to flash stock KK and OTA update to get L with a L bootstack, it did not work

I flashed CM12 ROM and updated phone with a KK bootstack but still it did not work.

I am out of options now. I cannot make calls with my phone. The same SIM works properly on my Nexus 4. My phone is not blacklisted, the IMEI has remained intact yet not sure what's wrong with it. :rolleyes:

Please help. I have seen lot of people reporting about D405 and D410 and have got their issue resolved but mine is D415 and do not see a solution yet for it.
[LG Optimus L90] lfom:
It seems that D415 has a different partition scheme (partition table), if it's messed it's hard to fix. If you have tried both KK and L bootstack with the appropriate ROMs as well as both KDZ, you may want to check the partition hack thread, make sure you use stock size and select a script that was verified for your phone's model.

[LG Optimus L90] xanscorp:
Flash back to KitKat, then flash the bootstack for KitKat. Boot the device for connecting the network. Afterwards go and flash the LP ROM but not the bootstack. Should be functional then. No idea why, but the L90 is not dependant on the LP bootstack, but the KK one.

Hello

just wanted to say version: Version: 2.3 worked for me on D415 TMO USA

got this phone in bootloop condition , trying to get into Download mode was not working and phone was falling back to some sort of Fastboot.

SO, I could not Fastboot flash recovery , it gave write error so I had to fastboot boot twrp.img,

then , to install Version: 2.3, I needed to copy the file to the internal SD via MTP with TWRP Loaded, because via SD Card it didnt work.

after successfuly installing the file I just went to download mode and flashed stock Lollipop Firmware...

Thank you, great solution.
[Xperia Z3 Q&A, Help & Troubleshooting] deecept:
Hi guys,

Just installed CM12.1, and I'm smitten, to say the least!

I'm pretty sure I'll feel right at home with it, and the immense tweaking that can be done.. (not least the change of scaling via DPI.. dear god)

However, I'm in a bind. My SCR24 isn't functioning properly. I have dug out what apks I can from system.sin file in the official FTF, but are missing some vital functionality

* Won't lock the screen when I close the cover

* Naturally no sizing to fit the screen on the cover, with no widgets

However, it does turn on the screen when opening the cover, so I got that going for me, which is nice.

I dug out 'cover-widget.apk' from the .sin file, but found nothing else.

Anyone in the know? Would love to make the CM12.x experience complete!

Cheers, and thanks for all the fish/help.

I just got the cardboard to try with the T6 Pro handset, like you I thought it would be a good match. Sadly the phone accelerometer appears to match the rest of the phone in that it is buggy and of poor quality. On first opening the cardboard app all seems well, movement of the menu but that quickly stops and no further movement occurs. Very disappointing.

Hi, it sounds stuck, not dead, I actully tossed my stylus at my screen one day, When it froze up, and caused a pixel to stick blue, after some work rubbing it out with the round of my fingernail, or the curved butt end of the stylus which almost completely removed it, and giving it a few days with diff color screens, it finally unstuck.

There are some apps that are supposed to help fix screens also for ppc's.

Might as well give it a shot, if youre considering replacement, it did take a fair bit of pressure, you should see it turn black, then release.

Opps, I didnt catch that second link, till I hit reply, but the first is one I tried, and I had seen one other, but it required the .net framework, I was too freakin out at the moment to really have patience with the apps, because the blue pixel was staring me right in the face on my black todaypaper.

If that doesnt work running it, I recommend setting a black background, and gently applying pressure, until you see the pixel go black, and then work it back and forth between red/black in a circular/orbital type motion over the pixel, if it doesnt fully go away, but appears more faint, just give it a few days, and maybe even switch out your today screen a few times a day, but just make sure it isnt red, even occasionaly massaging the pixel from time to time, thats tthe method I used, and mine went away, hope you have the same luck.

stuck pixels

I had a stuck pixel and I was able to get rid of it using a combination of the stuck pixel fix movie and rubbing. It's good to do it while the unit is warm or hot...like leave it in the car and then rub that area using moderate pressure. There are plenty of guides on the web to fixing stuck pixels on lcd monitors. Consult one of those.
