Just about all your questions have come up before!

So for example you will find references to this as the best speed test - all you do is tapit into your device browser:

http://www.dslreports.com/mspeed?jisok=1

You'll find references to this info:

"G" - GPRS, GSM and EDGE

"U" - UMTS and HSDPA

You'll find there are tweaks for changing the non specific nature of the above.

Try that google sticky at the top of the messages list.

Cheers

I am very happy to present first dualboot project for gt i9192. This original patcher is made by chenxiaolong and you can find original thread on gt i9505 original android development section. I only made some changes to original patcher. Big thanks to chenxiaolong for his awesome work.

I will not be responsible for your device to be bricked. Please proceed on your own risk.

Note : If you want to dualboot Touchwiz ROM with custom ROM please keep TW ROM as primary one. Also you have to debloat it to make space in /system partition for secondary rom. You can check the size of/system partition by diskinfo pro app attached in zip file.

Procedure : 1) First of all download the zip file attached below.

2) Boot in to primary ROM and install dualboot patcher app.

3) Open the app and set kernel as primary kernel.

4) Now patch the secondary ROM using dualboot patcher software on PC. ( do not patch using dualboot patcher app installed in primary ROM).

5) Reboot into recovery.

6) Flash the patched zip file for secondary ROM ( don't wipe anything just flash zip file).

7) Reboot.

8) You will boot in secondary ROM. Now install dualboot patcher app in secondary ROM.

9) Set current kernel for secondary ROM.

That's it. Now you can boot in either ROM by switching the ROM using dualboot patcher app and reboot.

The zip files to be flash for primary ROM need not to be patched but that for secondary ROM must be patch before flashing. To wipe data, cache, dalvik cache don't wipe through recovery directly. Flash the dualboot utilities zip file attached below in recovery. You will get to menu that let's you wipe the respective partition of either ROM. The normal nandroid backup will backup both primary and secondary ROM. To backup individual ROMs please see original thread by chenxiaolong.

Unfortunately android 5.0 ROMs are not supported by this patcher app.

For i9190/9195 users please install diskinfo pro app and check partition numbers if they are as below then you can directly use the patcher app and software.

system= mmcblk0p21

cache= mmcblk0p22

data= mmcblk0p24

If these are different then just change respective number using notepad++ as per your device partitions and you can use the patcher. You can also patch files manually for secondary ROM but autopatcher is much easy. The method is given in original thread by chenxiaolong.

So enjoy dualbooting and give me thanks if you like my work.

Thank you.

Can we install different based rom?

1. Cm rom

2. Tw rom

Otherwise it must be same based rom

Both Tw roms or both cm roms etc.
[Galaxy S 4 Mini Android Development] parthabhatta:
Was longing for this since long. Thanks. Well try this in off time
[Galaxy S 4 Mini Android Development] Sanesh Munde:
You must install TW as primary and CM ROM as secondary ROM.
[Galaxy S 4 Mini Android Development] loopguru:
Well done sanesh, will use and let you know the report,kindly try to add support for 'lollipop' also in coming days.
[Galaxy S 4 Mini Android Development] parthabhatta:
I confirm that it's working.

Details later

Edit : Details :

1)Primary: Samsung modded v2.5 by adityapal & others. Deleted many system apps and free space increased to 403 mb.

2)Installed DualBootPatcher and set kernel as primary.

3)Flashed CM11 by k2wl after patching it in PC. Device booted and found 23mb space left still now.

4)Installed DualBootPatcher and set CM11 kernel as secondary.

5)Can boot to any ROM from dualbootpatcher app.

6)Need to free some more space to flash Gapps CM11 after patching.

7)Made a Nandroid backup. A pretty large file.

8)Need to flash Dualbootutilities now.

Problems:

Cant patch chainfire supersu for upadting second ROM. The PC patcher goes into error.

Thanks to Sanesh to give us another thing to play with. Waiting for its update to become compatible with CM12 now.

A debloated flashable default Samsung ROM which will leave minimum 500mb system space free is welcome.
[Galaxy S 4 Mini Android Development] Sanesh Munde:
The basic idea of patcher is to patch META-INF/com/google/android/updater-script file. The updater-script file in supersu zip and some gapps packages is dummy file, so it cannot be patched by this patcher. I have tested it with different custom ROMs but only in Mokee AOSP ROM gapps package is installed. If you want supersu app in secondary ROM just download its latest apk file and install it then update its su-binary when prompted.

Just did that what you said in your last sentence. It was the only way left. Successfully patched and flashed gapps too. Everything running well till now
[Galaxy S 4 Mini Android Development] singh54:
Hi thanks for this work.... But have a doubt....

Should I have to keep a large internal memory or should I have to keep large system ROM level..... Attached a screenshot too.... Hope u ll understand d question.....

The reason I am asking is. When I try to flash the secondary it says installation aborted.... Status 7 error.....

Sent 4m My S4 Mini With Stock 4.4.2
[Galaxy S 4 Mini Android Development] Sanesh Munde:
Check all boxes in setting of diskinfo app. You will see system partition with number mmcblk0p21. You must clean some space in this partition by debloating present rom. To know how much memory you have to clean, simply extract secondary ROM zip file in PC. The amount of space acquired by extracted rom, you have to clean in system partition.

Sorry for my bad English.
[Galaxy S 4 Mini Android Development] singh54:
Have a Doubt.........

Hi,

You said, that if i want to install a custom rom over TW ROM then i have to keep the TW ROM as primary...

But my doubt is, i am already in a cm 11 based ROM, should i install another CM 11 ROM or CM 10.2 ROM over the first one by keeping the first cm 11 as primary and the another one as secondary...

Should i do the above, does it cause any problems..????

Will it works???????!!!!!!!!!!!??????????????

Please tell me buddy...............................
[Galaxy S 4 Mini Android Development] parthabhatta:
I think it won't create any problem. Only the secondary ROM and gapps need to be properly psyche patched. [MENTION=666195]sanesh[/MENTION]

Is the dual boot patcher (android and PC) updated for cm12?

Hei friend can u link me for 9195 project

Thanks
[Galaxy S 4 Mini Android Development] Sanesh Munde:
Hello friends, nice to meet you once again.

Xda senior member Chenxiaolong has made nice app Dualboot Patcher that makes our device dualboot or multiboot for lollipop based roms.

You can view the original thread here, http://xdaforums.com/showthread.php?t=2447534

Only remember to install TouchWiz rom as primary rom.

Procedure :

Download latest version of the app from here, https://snapshots.noobdev.io/

Install the app in primary rom and open it.

Go to Roms and set the kernel.

Now patch your favorite custom rom( you may patch it as secondary or for data slot).

Flash the patched zip through recovery( or you may install it from the app inbuilt function).

Reboot your phone, install Dualboot Patcher app in secondary rom and set the kernel.

You may install multiple roms in data slot. Also download dualboot utilities zip from above link and keep its copy in sdcard ready to use.

For I9190 and I9195 users simply unzip the rom before patching, go to build.prop in system folder and change

ro.product.device=serranods

Then zip the rom, patch it and then flash.

So friends enjoy multiboot and hit thanks if you like this post ☺☺?.
[Galaxy S 4 Mini Android Development] RuffBuster:
Nice! Will definitely give this a try on my I9195 LTE.
[Galaxy S 4 Mini Android Development] RuffBuster:
I have this working great on my i9195 LTE running debloated scStock and latest build of CM11 with the latest security fixes using small gapps package.

Had to alter the line "ro.product.device=serranolte" to "serranods" in build prop for primary ROM to set the kernel. And also the patched secondary ROM had to be flashed with the dual boot app otherwise from recovery you have to edit the ROM mod script to ignore phone version as it was originally compiled for the i9192.

But working great here using slimmed down ROMs. Now I have the best of both worlds, having stock features and app compatibility, while being able to use other ROM as my daily driver. And with one click of a shortcut and a reboot I'm able to switch very quickly. This is probably the best dual boot mod I've tried with a wide range of compatibility.

Having one issue though I'm unable to flash F4K's kit kat kernel patched or by including it within the ROM itself. Both methods normally work with this kernel under a normal single ROM installation. Apart from this is good stuff.

Normally, when a IMEI is gone, it's gone for good - unless you made an EFS backup. You can't use the EFS backup of another phone. I feel very sorry for you, and I sincerely hope you're able to claim your money back from the seller for false advertising.
[G2 Q&A, Help & Troubleshooting] d00lz:
[MENTION=4593047]Meppolan[/MENTION] unfortunately I cannot help but I really hope you find a solution as information like this is definitely important to share between all of us here. Thanks for taking the time to share this.

I will have to agree with this, the only way I've ever got my IMEI back was by restoring a Nanadroid backup (more importantly my EFS partition).
[G2 Q&A, Help & Troubleshooting] Meppolan:
Cheers guys, I'm hoping I can still revive it as the IMEI can be picked up by LG Flash Tools v1.8.1 as it shows up in the window. I was tempted to go to eBay and state my case, but I've already emailed the UK seller and he said he got it from someone of gumtree which don't help... I'll decide in a few days though!

Having same problem..

I'm also having same problem....

My Phone Model No. is LG G2 D802.....but when i opened the back cover of my phone it says different model no.'s like D800 at the bottom and D800 at the top right corner.......

So now i'm confused what to do and how to do........

All i want is to have root with custom recovery and to use Cloudy G3 Rom.........but don't know which autorec version to use (i.e D800 or D802)...

and if some how recovery is installed then while installing Cloudy rom which Model no. to select( D800 or D802)

I'm attaching the photos of the back of my phone......

I just dont want my phone Bricked....
[G2 Q&A, Help & Troubleshooting] Meppolan:
Remove your IMEI from here, never post that as stolen phone people will use it!

If you have a D802 ROM installed, you need to use ioroot to get root first, but then turn on ADB debugging and then backup your EFS before doing any more!

You can then restore the D800 ROM via the TOT method I have mentioned in my post. Download the D800 TOT file, use a hex editor inside it to change the model recognition in there to D802, and you'll be back in business with a proper ROM. and know what to recover!
[G2 Q&A, Help & Troubleshooting] elvis640:
Hello my friend! I come from a spanish forum where there's a specific thread for this problem you have, and let me tell you that, it hasn't been any type of resolution till the date, apparently is a very common problem when you buy a G2 from Aliexpress, this chinese retailer grabs a bunch of D800 version of the G2 and change treir IMEIs and back plate into the D802 version (don't ask how) obviously change the rom for another that match the new fake d802 imei, thats why at first glance there's no visible sign that in reality you have a d800 and when people update or change treir rom is when the problem come out to surface causing and irreversible damage to the cellphone although you have done an incredible advance, the pith is, the imei never was the original one so is almost impossible get it back.

---------- Post added at 04:51 AM ---------- Previous post was at 04:40 AM ----------

If you are not sure if your G2 d802 is not an original one DON'T flash or update your rom by no means!!! all you are going to get is a beautifull paperweight :o
[G2 Q&A, Help & Troubleshooting] Meppolan:
Aliexpress... I wonder if they can provide the file that flashed this phone then. I might ask them as I would be happy going back to that to be honest. I do feel my phone is a D801 though from looking at the parts!

[G2 Q&A, Help & Troubleshooting] jamesd1085:
If you can still view your imei on anything on pc then it is more than likely still intact...the efs partition may have become slightly corrupt or something may have screwed up the format...do a little research on which partition efs is stored on and what format it gets mounted as when system boots...it seems to me it just isnt mounting properly as i had the same issue on my gs4 but there are apps specially made for samsung devices...im sure there is a fix for your issue...its finding it that may be an issue...my device was down for three months before i found a fix...dont give up!
[G2 Q&A, Help & Troubleshooting] Meppolan:
I used the steps in my first post to get a stock ROM for D801 on, then used the normal KitKat rooting my phone (via TowelRoot) and installing TWRP (via AutoRec). Then I copied the ROM to a folder on my phone, booted to recovery (you have to turn off the power of the phone, then hold down Vol- and power when turning back on, soon as the LG logo pop ups, release the power and press it again and hold quickly (still holding vol+ all the time) to get into factory reset. Release all buttons when you see it loaded, then press power putton to perform the reset, but it will just load up TWRP to install your ROM).

I saw the Samsung ones and tools, but can't seem to find anything that will help unfortunately. I'm wondering about doing a FULL wipe of the phone and trying to flash on everything to see if that helps but not just yet. I'll open up my phone some more soon and remove the motherboard to make sure it is a D801!

My major issue now is that the download modem is stuck and can't be load properly, no need to mention that the device isn't recognized on this mode and whatever driver was installed was in vain.

When the device is just powered on ( stuck on LG screen), it is recognized properly.
