Database Develop

*MODS* Just you you ;) [R&D] Samsung Snapdragon 800 harmonizing

Dear Moderators!
Since I had top stop being active in the development the threads that I started with having a master directory and thus that are left here has become totally stale since they have not been updated in a long time nor do I have current plans to continue.
I don't track this forum and the wonders done with this phone but this post has some real potential danger.
The post is outdated and the information in it could therefore be wrong, faulty or even harmful. And I see it mostly harmful in my point of view, since this was the baby steps taken a long time ago.
Looking at the contents it compares several parts of partition tables and even brave (and foolish) tries of me testing philz recoveries. Now Philz has put some safety code since the Note II/S3 melds but for a less experienced user that look at the names.
"hlte and jflte", sound pretty close that we know is not the case but they reeeely want so badly into the "world" of S4 they could try to alter the partition tables, that we serve them on a platter and that there are easy utils for, to TRY make it look like the "real" S4 and really hard brick the phone, or even worse try TWRP of the hlfe "since it was so long time ago" and look at their screen melting away.
Proper scientific rules dictates that if any information is unknown and therefore in a volatile state it should fall under the principle of caution until verified of its validity and safety. I have no insight into that validly and the current development but I highly doubt this post is needed any longer and since this is accessible to the public the "not doing any harm" comes into place and thus this thread should be deleted since if anything useful came out of it it has already been taken into current development and it can cause harm. A lock will not suffice.
Since I know that many posts are not considered being "device specific enough" (like a discussion about lowering the voltage of the kernel) or "cluttering" (explaining the booting process of a kernel works) this post should absolutely fall under some of those rules (or some other that I've yet not encountered) and I strongly think a deletion of this would be more proper then just moving it to the trashcan "General"?
So at least I try to make you see that this post should not be in the trashcan but deleted for the safety of less experienced users.
You can say that they are then stupid. I call them inexperienced. I tried to so many times to post and raise the level of knowledge and we all know where those writing for 8 hours posts went, right?
But this is not about being ignored from "higher devs" about my finding of a side channel attack in the bootloader in 4.3.
This post is just not a safe for those unlucky who got this ****ty phone on their warranty (I got one too). They feel cheated and I understand them.
It's useless, can't use the S4 and not the N9005 stuff. The guys here did an amazing job with it but I had leave. But someone can really do something stupid and and this post gives false "hope". I got some "Pit"-file. Lets try that one...
Since this is also a stub for a "collection" that I also could not finish and I don't recall if I did something more of those but I know you are pros of finding nonsense like this and could you please remove that "clutter" as well?
All the best,
Absie
Abstract
This thread is about testing and finding similarities and differences between the currently two Snapdragon 800 Samsung smartphones, namely the I9506 and Galaxy Note 3 (SM-N9005, hltexx). What we know so far is that they use the same hardware and production line and are separated quite late where they diverge. The theory is therefore that the Samsung Note 3 LTE binaries should work since the development here is non-existent and the similarities are larger between those two then with the previous S4, I9505. The work seem not as straight forward and so far binaries from Note 3 have been incompatible and this thread is about finding our just WHY this is so and how we can try to overcome those problems and have some porting of available ROMs from the major project branches. Similarities with the previous S4 (I9505) will be investigated along the progress of this thread. Since this device is shipped with Android v4.2.2 and without KNOX activated we also need to investigate what activates KNOX and how to avoid that.
Collection of findings
This is a stub of the different pages that will be updated as the progress is ongoing and will be updates as we move along and collect the findings.

General Findings​
Things we know
The I9506 and Note 3 (int) are based on the same board and therefore they should be interchangeable.
The Pit-files (Partition information) are identical for the both devices except for the obvious, larger screen, more mem and bigger internal data partition. All other partitions are exactly the same and lies on the same place in the Flash which should porting much easier since the core partition layout is the same and makes it much easier and safer to try different versions.
The initial tests done with trying different Custom recoveries has not worked.
Things we don't know
Are the kernel interchangable? Here we have note yet had a 4.3 for I9506 to compare but Samsung has started to roll out that. Knox is then activated.
Differences between other partitions and their content
Questions that need answers (volunteers are needed!)
Now that we have at least 2 versions of the 4.3, we need to hunt for the same releases made on Note 3 and compare them.
Why is not Custom recovery working? Is it something simple?
Does anything from the I9505 work? Are there any similarities there?
.

Custom Recovery​
So far we hare 2 custom recoveries (links will be provied).
No custom recoveries from Note 3 has yet been working.
The following recoveries from Note 3 have been tested and found not been working my normal replacement in Odin
Philz_touch_6.04.1 - (Give the first BSOD! Blue! Blue!)
Philz_touch_6.08.9 - (Seems like the screen is melting)
Openrecovery-twrp-2.6.3.0 - (Black screen. Nothing happens)
You can all try, those who has 4.3 and Knox 0x01 could test those. It seems a bit scary, but at least for the the "pull the battery and reinstall a normal one with Odin" worked,
but as usual, this is work that need to be done and nobody here can promise anything. Brick/unbrick, but you might be the hero if you get stuff to work from over Note (like a kernel).
So I have something to fill the next post with?
Who initially provided the working custom recoveries and what was done to make them work?
Please PM me if you don't want to write it here.

Hi Absolon.
Probably because a different portion table. Our is even different from the GT-I9505.
I'll post our full partion table, as it looks on our phone. Just need to get home and fire up my Ubuntu/Linux.
See ya'

I made the Pit files yesterday from the two devices and the are the same.
Same size, same memory adresses.

Did you see the PIT-files I sent you yesterday?
Those where the same. Exactly the same. So how can it differ?
I posted them above this reply

Try to run the command: ls -al /dev/block/platform/msm_sdcc.1/by-name
Do it in a terminal.
Btw. Does anybody know why I can't upload screenshots and other stuff???

I just compared the 2 .txt files in excel
The result are in attachement >
Cell B is BASE
Cell A is compared with Cell B
- Everthing green in Cell A is identical with Cell B
- Everthing white in Cell A is different to Cell B
You can also compare to this ref thread [DEV][REF][INFO] Partitions GT-I9506

My dear friend, please zip your files, I don't use rar in Ubuntu.
Have to switch to Windows and back...lol
Somethings wrong with my account here, it log out out after a few minutes, can't add pics etc...
But at least I can get in now on my laptop. Might have to cantact the Mod.
See ya'

Nice thread, i already have the i9506, and i will get my Note 3 as a company phone on wednesday. I'd ble glad to help!

I created my I9506 files from my phone.
All XDA related content will be placed here for reference and PM me your gmails and I give you r/w there.
(changed the link since someone tried to read INSIDE a rar file in gdocs. There is a zip there now as well)
So, as you see, I got the same values, just that you didn't give you any?
We do have exactly the same layout
We know it's the same board
We have recovery that is working
N9005 recoveries are NOT?
Any idea?
Who had the "mended" Philz from start? What was changed so it would work?
Because if we can figure this out it looks promising. If we can't then we need to start trying (need that anyway) compiling stuff and go from there.
But I thought it would be interesting just to check if it would work or not. Damn it...

Yes, I will use the algorithm that was invented in 1978 (ok 1989 and I have NO IDEA why Google chose that when there are so many more effective alg that are OS)...
I can use LHA, or even a C64 cruncher just to get you start working dammit
And btw, unrar if freeware

[ HOW-TO ] - Resizing partitions (Universal Mode)

I wrote this How-To several months ago and published in a spanish forum.
Now I've recovered to share here as it may interest someone.
This was originally written in spanish and now, our friendly companion @nachordez
has been kind enough to translate it to english. Thank you very much for your help. :good:
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
I'll try to explain here how to change the size of our device partitions.
Though the presented data are referred to a 16 GB, a p5110 in this case, they are easy to adapt to a 8 GB one, and/or any other model, with some light corrections.
There can be other ways, but this one has the advantage that depends only on not writing wrong data, and that's easily achieved with a little extra concentration during our work.
Anyway, it's needed to follow very strictly this how-to.
In case of total failure, we should restore the tab through the flashing of a Stock version using the pit file.
ALL the data not saved in the external MicroSD card WILL BE LOST, 'cause we'll delete the /system, /data and /cache partitions.
What is needed:
A computer.
A properly running adb program.
Recovery installed.
External MicroSD card installed and with available space.
Connection cable.
Full Battery.
For 3G (GSM) models, the original “modem.bin” file, obtained from a stock ROM.
The modem.bin file is not really needed as we can get it from our tablet with next command
dd count=40960 bs=512 if=/dev/block/mmcblk0p8 of=/external_sd/modem.bin​
All process is done from computer, except a short intervention at end, done from tablet.
This how-to is planned for a AOSP-like ROM, such as CyanogenMod (for example).
In the case of a Stock ROM, the partition sizes we are adjusting will be too short for it.
Before starting:
We have to check that there is enough free space in the MicroSD card, and we have to do a backup through recovery, choosing EXTERNAL SDcard.
If the internal one is used, IT WILL BE LOST DURING PROCESS.
This step is very important, to recover the ROM without re-install from zero.
So, let me say it again: EVERY USER DATA that has being not COPIED to the EXTERNAL SDcard, WILL BE LOST.
After next steps, ONLY the external MicroSD will be conserved without erasing.
So, we check once again that everything is saved, and copy to the external MicroSD (if our tab is a 3G model) the “modem.bin” file that will be needed afterwards.​
So... Let's start hacking!:
We always wrote in our PC.
We reboot our tab in recovery mode, and connect the cable.
To enter the tab from our computer:
> adb shell
Once entered correctly on the tablet, we like more clear ls command:
> alias ls='ls -an'
Now we access the partition table:
> parted /dev/block/mmcblk0
We'll get something like:
GNU Parted 1.8.8.1.179-aef3
Using /dev/block/mmcblk0
Welcome to GNU Parted! Type 'help' to view a list of commands.
(parted)​
The command line for parted is (parted), so, every time a line starts so, that what follows this is a command.
We ask for information about current partitions:

10........ 2278MB.... 15.2GB.... 12.9GB........ext4............... DATAFS
11......... 15.2GB..... 15.8GB.... 537MB....... ext4............... HIDDEN​
Comments:
Analizing the current partitions we can see this tablet is a 16 GB one:
/cache (CACHE) has 734 MB assigned
/system (FACTORYFS) has 1468 MB assigned
/data (DATAFS) has 12,9 GB assigned
There's also a funny 537 MB partition called HIDDEN: that's where the Samsung video, musical theme and demo pictures are stored.
If I don't mistake, I think I extracted them time ago, and they were just about 14 MB. In our case, we'll opt for destroying that!
In this how-to we'll assign:
/cache (CACHE) 400 MB
/system (FACTORYFS) 600 MB
/data (DATAFS) the sum of: its current size + 394 MB from CACHE + 868 MB from FACTORYFS + 536 MB from HIDDEN.
So, we'll grow our /DATAFS space in 1798 MB, which will mean more than 14 GB free space.
I use in this example 600 MB for /system was what I did in my tab.
In real world, 240 MB /cache and 500 MB /system are more than enough.
As we'll see later, all this numbers are just aproximations, not completely exact, and probably you're thinking: “My maths do not agree with this numbers”. Mine do not, also, as a fact.​
Let's see all that more slowly:
21+2+2+8+8+8+21+1 (for the 'hidden' partitions) give us 71 MB.
If we add 71 + 400 +600 we'll get 1071 MB.
If we have 16 GB and we use 1 GB, more than 15 GB should rest.
On one hand: 1 GB are 1048 MB. So, 16 GB should be 16768 MB, but we have just 15709.
That has a easy explanation: The hard disk makers started to measure 1 GB as 1000 MB (kind of a commercial trick). So, just beginning with that, 768 MB have disappeared in thin air.
On the other hand, we have 34 initial sectors to sustain the partition table, alternative sectors for errors recovering, rounding of numbers in sectors to partitions assignations, etc.
We have 11 partitions just now:.............................................. And they should get like that:
01 00021 MB...........................................................................01 00021 MB
02 00002 MB...........................................................................02 00002 MB
03 00002 MB...........................................................................03 00002 MB
04 00008 MB...........................................................................04 00008 MB
05 00008 MB...........................................................................05 00008 MB
06 00008 MB...........................................................................06 00008 MB
07 00734 MB...........................................................................07 00400 MB *
08 00021 MB...........................................................................08 00021 MB
09 01468 MB...........................................................................09 00600 MB *
10 12900 MB...........................................................................10 14638 MB *
11 00537 MB...........................................................................11 00537 MB
.....15709 MB................................................................................15709 MB​
The difference can seem small compared to the original partitioning, nevertheless will allow us to get all our usual apps installed and, even so, preserve a free space higher than we had previously, even before than start to install anything. That's saying: even more than with a pure CM just installed and not even configured.
Obviously, if we translate all that to a 8 GB model, the proportional gain is much higher.
Also, consider that an AOSP rom like CM is not bigger than 460 MB in /system, and that cache will need just 60 MB for dalvik and what we can download from google-play at a certain time. 170 MB should be enough, unless we want to download an app bigger than 100 MB. The bigger ones I've saw are around 90-105 MB.
In this moment, we'll have to decide if we want to follow on or not.
Till now, I was just fun, but nothing has being 'broken'.

We can see easily the ratio between MB and sectors: 4096 sectors equal 2 MB, so 1 MB are 2048 sectors.
Now, we'll delete the last partition, 'cause starting with it will make work easier at end.

So, we have a 1 MB partition that previously was a 537 MB one
Yes, you're right. I've changed last sector from 30777309 into 30777310. I haven't added one new sector to disk, it was yet there, but unassigned.
This is so 'cause I want the total to be an even number of sectors, and also this partition sectors number has to be even.
Previously, this partition had a name. So, let's be polite with it:

Done. Now, we can forget it, and not even format it.
So that it is the last partition, and will not be used, all this work was really unnecessary, but, preventing the case that any process could count partitions, we keep home tidy.
OK. By now we have:
Deleted partition
Created partition
Named partition
If we have a previously calculated chart, we'll just have to do next steps for each partition and we don't need even to look at it, just to check at end if the obtained result was the one expected.
Anyway, in this How-To we'll do things one by one.
We shrink the CACHE partition
We calculate: 400 x 2048 = 819200 (400 MB x 2048 sectors = 819200 sectors)
106496 + 819200 = 925696 -1 = 925695
Our new partition starts in sector 106496 and finishes in sector 925695

So, that's what we got. It seemed difficult, but it's done!
Finishing:
We exit parted, for the end of feast using quit command
(parted) q​
In this moment, we've returned to recovery.
Now, and only if our tab is a 3G/GSM one, we have to recover the modem:
dd count=40960 bs=512 if=/external_sd/modem.bin of=/dev/block/mmcblk0p8​
Format:
Remember that we are in recovery. So, let's go to tablet and we select:
- mounts and storage
Search for and click on:
- format system
- format cache
- format /data and /data/media (/sdcard)
Just and only this options.
To check, now click on:
- mount /system
- mount /cache
- mount /data
If everything is OK, each one of the 3 options will change into unmount​
If you are an expert user, surely you know how to format from shell, without using recovery options.
WE HAVE FINISHED. HURRAY!
Now, we have two options to reinitialize:
We install our favourite Rom, boot, configure, restore data, etc.
Or we restore the backup we did with the recovery in the external MicroSD card and we remain as if nothing had happened (but with lot more free space).
NOTE: I've wrote this how-to using CWM recovery, On others recovery, mount options can be slightly different

I have cyanogenmod installed over tab 2 7 inches 16 gb which I want to change but flashing stock firmware is not possible as it gives error....I feel something is wrong at partition table. I want to repartition for stock rom. ...can u guide

Did you ever edit partition table of your tab? If you haven't, then nothing is wrong with partition table and no need to repartition it. Installing custom roms don't change partition structure.
You should start a new thread and post exact problem there only.

If we resized the partitions, maybe all custom rom would not boots?

Don't worry, as long as the rom sticks on the partition (specially system partition)

If you set the correct path for Partitions and available space/filesystem is correct, you can play with partition table as long as you want.

btw I had strage issue. After whole process I couldn't format my cache partition. I tried to remove it and add again but it didn't help. Hopefully solution was easy: I had to reboot my recovery. Now everything is fine
Thanks for great guide
p.s.
repartitionig is preatty easy but i've spent more than hour trying to fix adb drivers

btw some ot
If you repartitioned your galaxy tab it doesn't mean that you can repartition every other android device. I made that mistake and I've just hardbricked my xperia phone trying to repartition it (I belive it's somehow protected). My bootloader died so it's impossible to fix it at home. Keep it in mind before you try to repartition your other device.

Repartition system might cause issue flashing some/most lollipop roms because of blockbased implementation.

So, how to revert. I want to flash your rom and I cannot.
Do I have to revert to stock? Or is someone having the original partition?

Omni 5.1 and AOSP 5.1 should work i think. Or stay on KK.
Theres a different way too, let me see if i find it.

Thanks. But where can I find the system.tar for this?
And the last Omni founds no mirrors for download on your AndroidFileHost
I do like Lollipop

I flased omni 5.1 on my repartitoned tab and it works but 600 mb system partiton is too small for heavy lp rom and some of my favourite gapps so I decided to change partition layout again. I think that 400mb for cache it too much, my new moto e has 8 gb of storage too and only 256 mb of cache. So I changed my layout to: 256mb cache, 800mb system and rest for data. So I lost only 56mb of my data partiton while boosted by system by 200 mb so I think it is worth. Here are my commands (I think that they looks more clear than table):
I have 7'' 8 gb model
Code:
(parted) rm 7
(parted) mkpart 7 106496 630783

I solved the very same problem by flashing stock AND the special .PIT file for my version (beware: there are a 8GB and a 16GB pit files)

[D405N]Lost IMEI, need help to restore

After trying to install twrp, my phone bricked.
I managed to unbrick it and flash stock 5.0.2 .kdz ! Through the procedure of unbricking, I performed a low level format which erased everything including my /efs partition and everything included in it.
Therefore my IMEI is currently 0 and my IMEI SV is 00.
I have tried to install my IMEI through QPST but it will not connect to my phone as it will not recognize it (No ESN, No Phone Connected).
I have tried to connect to my phone through CDMA and EFS Professional but still the same.
During my search on the forums, I found that Ishould enter DIAG mode in my phone, but I cannot find an option for this.
LG said I am not covered by warranty as the /EFS partition is not something that could be wiped without root or a modification to the system.
The main problem is that I do not have a backup. Please help me,
Thanks in advance!

If you had a backup made by TWRP then you could restore your EFS partition. Unfortunately I don't know any other way to fix it.

That's the thing, my whole trouble begun when I tried to install TWRP!

I'm not sure how could you destroy EFS partition with installing TWRP. You should have stick to instructions.

TWRP didn't kill my partition, unbricking the device did! Plus If you can't offer a solution or any kind of help, don't answer at all! I am not here for judgement!

I'm not judging xD
I'm trying to understand how did you exactly destroy your EFS partition. You didn't provide enough information about it, except saying that you did some kind of low-level-format (you didn't mention how or why). What surprised me was that installing TWRP doesn't require to perform any low-level-format. That why I wrote about sticking with instructions. Then you wrote that you messed up your phone while trying to install TWRP and got you IMEI lost during unbricking. You didn't wrote what exactly meant bricking and what "procedure" did you performed to fix your phone.
My point is that you should have written exactly what happened, not only how you got there and what did you tried to do to fix it. In my opinion it's hard to propose any solution when we don't know what exactly did you do.

Also, unbricking your phone with other variant image will destroy your radio info and I don't know if there is a way to recover it in L90. Even if you use your variant image, but from other phone, it will probably overwrite your unique info, that's why it's wise to make a backup of your phone after rooting with dd if=/dev/block/mmcblk0 of=/storage/external_SD/unbrick.img bs=1024 count=168960 - this will be YOUR phone backup, don't share with anyone and store it in a safe place.
Back in time when I had the Optimus 2x, it was possible using Tutty (debug mode ON) and accessing LG debug (in our L90 it's 3845#*VARIANT# e.g. 3845#*410#), of course you must use the IMEI printed in the sticker in the back cover (this is not possible anymore FYI).
Actually, there is not EFS partition in L90 indeed, instead, the IMEI and other radio info are stored in modemst1 and modemst1 partitions. As I suspected before, unbrick images takes some NAND blocks and writes to an image file - it takes the partition 1 to 15, which includes modemst1 and modemst2 partitions (11 and 12). These partitions are also not flasheable via KDZ (these partitions are absent), so before doing any modification after rooting your phone, do yourself a favor and backup modemst1 and modemst2 partitions, because if anything goes wrong, unless someone find a way to inject the right IMEI data in modemst1 and modemst1 image files for further flashing, you will end with a "radio brick".
Found a tutorial here at xda how to backup and restore modemst partitions : http://forum.xda-developers.com/lg-g3/development/efs-lg-g3-efs-backup-restore-t2907329

I had the same problem.. I unbricked my phone by low-level format tool .but now I don't have mobile network signal.but I have an twrp recovery .did they help me..

Text partition d415

Hopefully someone here could possibly pull their partition file from their L90 D415 and upload it here, it seems I need it for a possible way to unbrick my d415. The way I found seems to work for all other variants, though from what i've read others with the d415 model have no success, and it is probably due to a different partition table. So please, if one could, post a link or something for the partition text file. I really need it a long with others I assure you. It would be greatly appreciated. Thank you, and have a nice day.

You can find lots of info about partition table here:
http://forum.xda-developers.com/lg-...ck-partition-table-tool-lg-l90really-t2946323
Probably it includes info for D415 as well. Hope it helps.

If you can get it to boot to recovery, there's a partition tool (executes from recovery) that will fix it up for you. U might be able to get the table from the app itself. Otherwise I have d415 and will get u what u want from mine. Lmk if u still need the help with that

[GUIDE] Increase your Nexus 4's system partition for more space!

I got tired of installing amazing ROMs created by the talented folks here on XDA, but being held back on things like Google Apps because of the tiny /system partition we have on the Nexus 4. I looked around and found guides to increase the system space in the Nexus 5 and Nexus 7 2013, so I basically just adapted them to work on our beloved Nexus 4.
As always, do this at your OWN risk. I am not responsible for bricking your Nexus 4. I will simply list the process which I used to increase my Nexus 4's system partition (by taking a big ol' chunk from the cache partition). Remember, any sort of modification to your device of this caliber WILL void any warranty you might still have.
REQUIREMENTS:
parted (Uploaded to my Google Drive. If it downloads as a .txt, rename it to remove the extension and make it a plain file)
adb and fastboot, and preferably knowledge on how they work
Step 1: Install TWRP onto your Nexus 4 and reboot into it.
Step 2: Open up command prompt / terminal and check to see if your Nexus 4 is connected properly with "adb devices".
Step 3: Once you've confirmed that adb is fully working and your Nexus 4 is properly connected to your PC, download parted and use adb to push it to your Nexus 4 using the command:
Code:
adb push parted /
Step 4: Now enter the following command:
Code:
adb shell
and then the command:
Code:
chmod +x parted
This will enter adb shell and make the "parted" binary you pushed to your device earlier executable.
Step 5:
Now run the command
Code:
./parted /dev/block/mmcblk0 p
You should see a long list with a bunch of numbers and names in your terminal. These are the partitions on your device. parted will give you the partition number, the "start" and "end" of the partition, the size, and the name.
This is the partition layout on my device. It will probably be the same on your device, though the size of userdata may vary depending on whether you have the 8gb or 16gb Nexus 4.
Code:
~ # ./parted /dev/block/mmcblk0 p
Model: MMC 016G92 (sd/mmc)
Disk /dev/block/mmcblk0: 15.8GB
Sector size (logical/physical): 512B/512B
Partition Table: gpt

19 126MB 143MB 16.8MB misc
20 143MB 159MB 16.8MB ext4 persist
21 159MB 1040MB 881MB ext2 system
22 1040MB 1627MB 587MB ext4 cache
23 1627MB 15.8GB 14.1GB ext4 userdata
24 15.8GB 15.8GB 524kB DDR
25 15.8GB 15.8GB 507kB grow
Step 6:
Now run the following three commands:
Code:
umount /data
umount /sdcard
umount /cache
Step 7: So, on my Nexus 4, the system partition is number 21, and cache is 22. We're kinda lucky in the fact that system and cache are right next to each other, meaning we don't have to touch any other partition.
You'll want to run these two next commands. These commands will essentially "remove" the two partitions.
Code:
./parted /dev/block/mmcblk0 rm 21
./parted /dev/block/mmcblk0 rm 22
Step 8: Now it is time to recreate these two partitions, however, when recreating them, we will make system bigger and the cache smaller. From the partitions list we got in Step 5, we can see that system starts at 159 and ends at 1040, while cache starts at 1040 and ends at 1627. The following two commands will rebuild /system starting at 159, but ending at 1590, while rebuilding cache at 1590, and ending at 1627. We are essentially stealing a large chunk from cache, since we don't really need that anymore on newer ROMs.
Code:
./parted /dev/block/mmcblk0 mkpart primary 159 1590
./parted /dev/block/mmcblk0 mkpart primary 1590 1627
Step 9: Now run this command:
Code:
./parted /dev/block/mmcblk0 p
This will bring up the partitions list, or table, again. This time, however, we'll see the new partitions where system and cache were, however, they have no names! The following two commands will name the two partitions again.
Code:
./parted /dev/block/mmcblk0 name 21 system
./parted /dev/block/mmcblk0 name 22 cache
Step 10: Great! Now the partitions should be named again! Now, we still have to format the partitions as ext4 so that we can actually use them. The following two commands will do that for you.
Code:
mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p21
mke2fs -b 4096 -T ext4 /dev/block/mmcblk0p22
Step 11: At this point, feel free to run the command from Step 5 to take one more look at the partition table and make sure everything looks good. Now run the command
Code:
mount -a
and then type in
Code:
exit
.
Step 12: Now we are pretty much done. We've extended the system partition from approx. 881mb to 1431mb, which is a nice large chunk of memory. In the future, we could always mess with the partitions more to add even more space by stealing from userdata, but until we reach that point, I think we are pretty well set for now!
Now...
You'll want to reboot TWRP, and flash a new ROM. You can now use a much bigger Google Apps package, without any worries.
Do note, however, that flashing a ROM will "resize" system to be smaller, but this isn't a huge deal. After flashing a ROM, while still in TWRP, you'll want to go to Wipe > Advanced Wipe > check "system" then head to "Repair or Change File System", > then tap on "Resize File System." If you encounter any errors while trying to resize, try remounting system or rebooting TWRP. Afterwards, you should be able to flash your Google Apps package. I'm not sure if you need to repeat these steps after flashing things other than ROMs, but repeating this process within TWRP should work just as well.
I hope I helped y'all out and feel free to post if this guide worked for you or if you have any other comments!

thank you very much !

Thx !
Thx !

Great guide works perfectly.. has anyone tried to reverse the process and go back to stock to reflash a factory image?
I just tried it on my old Nexus 4, and after resettting the partitions, and reflashing the factory image, its just a permanent bootloop. I've cleared all the cache, tried a wipe from the stock recovery, tried flashing TWRP and wiping there.. nothing seems to work. Im not too worried, but it'd be nice if it could boot again.

Thanks for your guide. It worked like a charm for my Nexus 4.
Just a small addition: To resize the system partition automatically I placed a script in /system/addon.d:
Code:
#!/sbin/sh
#
# /system/addon.d/10-resize-system.sh
#
. /tmp/backuptool.functions
case "$1" in
backup)
# Stub
;;
restore)
# Stub
;;
pre-backup)
# Stub
;;
post-backup)
# Stub
;;
pre-restore)
/sbin/resize2fs /dev/block/platform/msm_sdcc.1/by-name/system
;;
post-restore)
# Stub
;;
esac

If it doesn't work for you
Thanks for this great guide!
Decided to breath some new life into an old N4 in my family and now it's going (very) strong again with LineageOS 15.1. Still had to clear a bit over 100 MB with .gapps-config from Stock-OpenGapps, but that's no biggie. I always liked to start with the big package and then remove everything that I don't need from it.
Second issue gave me some headaches at first.
"Resize File System" in TWRP apparently worked and Gapps-Install went through (~100 MB free at the end), but boot would fail and crash back to recovery.
(I'm using the daily LOS-nightlies by Milaq and Stock-Package from OpenGapps, maybe it's no problem with other ROMs and/or Gapps-Packages.)
Turns out the fix in TWRP wasn't really working, nevermind what partition size it shows for /system afterwards. It's somehow corrupted and still has the original size -> most of the gapps stuff get's written to nirvana, thus the failing boot.
I found the solution over in the Nexus5-Thread:

Hello guys!
Try this:
1) Install ROM
2) Backup ROM
3) Enable "Use 'rm -rf' instead of formatting" in TWRP settings
4) Format /system
4.1) Unmount /system and use 'resize2fs -f /dev/block/mmcblk0p21' in terminal (TWRP)
5) Reboot TWRP
5.1) Uncheck "Use 'rm -rf' instead of formatting" in TWRP settings
6) Restore backup
7) Install Stock OpenGapps
8) Done!
The idea behind it is that ROM installation somehow corrupt /system partition thus any write operations above normal data region silently fail.

at step 4.1 I already changed the partition number to 21 for Nexus4. In the original post it says mmcblk0p25, because on the Nexus 5 that's /system.
Now it works.
In theory this procedure should also work for updating the ROM without losing data, but haven't tested it yet. (Maybe throw in a wipe of /system as step 0...?)
To be clear: This isn't the fault of the guide to resize system-partition.
Problem is (at least certain) ROMs resetting size of file system to original and then TWRP failing to fix that doing it the easy way as described in OP (-> bug in TWRP?).
EDIT:
Above procedure also works for an update without data loss. Only difference was I did a normal wipe of /system first, "step 0" so to say.
No idea if all this is still necessary with TWRP 3.2.3-0, I'm not willing to risk a full wipe at this point. ^^

i need this...can't even install the smallest gapps package after oreo.... word!! thanks!

Really wanted to thank-you for this!
Two questions:
1. When you printed the partitions, system (21) was ext2. When you recreated it after resizing, you created it as ext4. Was that intentional?
2. You also made the claim that modern ROMs don't need such a big cache partition (your new one was 37MB, I wasn't so brave). Can you justify that claim or provide some technical details? It's not that I don't believe you (I trusted you enough to do this on my device!), just merely curious as to why/how this would be.
Thanks!

I'm using TWRP 3.2.3-0 and it has this bug, too. After I followed your steps I was able to install Nitrogen OS and Open Gapps Micro in my phone without erros.
Thanks!

I believe that resize2fs step can be packaged as a flashable zip so we can batch flashing without manual intervention to it (i.e. manually resize fs on system after each rom flash) .

Maybe then more users would dare to use this solution and could calmly install gapps on Pie.
You have a lot of experience. What do you suggest?

Hi all. I only discovered this thread after independently figuring out the partitioning scheme (plain GPT) and process.
Sadly, even after this effort, it seems L-OS upgrades won't work unless L-OS devs modify their upgrade script to make use of resize2fs. Here's what happens as of package 2018-09-11:
L-OS runs backup procedure for all addons found in the existing /system/addon.d/
The above creates files (I guess) in /tmp
The /system is unmounted
The partition is overwritten with the image in the upgrade package
The script in addon.d/ are then run to restore the addons from /tmp
The problem is, the partition image in the upgrade package is for the old partition size, and therefore step 5 fails when the free space runs out. It seems the install or restore scripts don't detect this failure, and just exit without reporting an error, with 0B free space on /system.
I'm guessing the problem can be "solved" by formatting the system partition and installing LOS and all addons from scratch, but that's ridiculous. has anyone tried to raise this issue with devs? I'm about to report this in L-OS's JIRA, as I haven't seen any relevant report there.
EDIT: If anyone wants to track: https://jira.lineageos.org/browse/BUGBASH-2306

You may be able to fix that on your own by adding an add-on.d named 00-resize-system (so that's it's ran first) that just does "resize2fs /dev/block/.../system", with maybe an unmount before and a mount after. This way, LOS can just flash the full image when upgrading and the system is resized before the other addons.d scripts run.

Thanks for the tip, will give that a try. Any idea where I could find an "authoritative" docs/guide to those scripts? Just looked at the one supplied by open g-apps, and I don't really see the difference between the various commands that the script is supposed to handle (which is executed when?). Also what list_file() is supposed to provide.
backup
restore
pre-backup
pre-restore
post-backup

You want to put the resize2fs call in the pre-restore section.
It should look like this:
Code:
pre-restore)
unmount /system
resize2fs /dev/block/platform/.../system
mount /system
;;
This includes unmounting and remounting /system which I think are needed, but YMMV. You'll need to fill in the full path to system under /dev.
There is no authoritative resource for backup scripts that I know of, but the gapps script is a good example.
P.S.: If you make it work, please post the script for others...
