Should I be worried, corrupt partitions - Galaxy S II Q&A, Help & Troubleshooting

Hi All,
Wondering if you could help me please... I keep getting this message from time to time, but not constantly.... My setup is as follows...
Device: Samsung Galaxy S2 (i9100 standard, not P or G model)
OS: BeanStalk 5.0.2 (Android Lollipop 5.0.2) and BeanStalk 4.4.4 (Android KitKat 4.4.4) / dualboot
Kernel: Kernel_Dorimanx-V10.44-_18-28_-_26-01_-KK-b2-SGII-I9100.zip (running Build #2, as build #3 was slower and unstable for me)
PIT: 4GB /Data partition on primary OS (Lollipop). When dualbooting, second rom seems to see/work like stock layout of 2GB /Data
Setup: BeanStalk 5.0.2 is primary rom, BeanStalk 4.4.4 is secondary rom. It's the secondary rom I get the errors on.
Should I be concerned about this error message, will it cause long term data corruption and kill my phone...?? Or is this normal under the S2 and dualbooting...? And just need to run a util once in a while...? Could this lead to eMMC BrickBug issue, like on the N7000... as it has a similar chip.
Many thanks, Lister

If there's no problems now, it should be fine to ignore this issue. You could enable fix data and see if this removes this message (it should) but there's really no need to enable it unless you start to see some issues.

Korean YP-GB70? Q&A Rom & Kernal

I am looking around this thread has anyone seen anything on YP-GB70 or is this the same as YP-G70? It is from Korea. I guess steve's kernal is NOT compatible with this device. What Kernal / ROM is? Any suggestions
Korean YP GB70 root and non root kernels (firmware KPH)
Hello,
you can find root and non root kernels for Korean Samsung Galaxy Player YP GB70. It is flashable only over the last KPH firmware (as of March 2012). As I cannot yet post links to outside pages (new user) try to decode the URL from this:
HTTP doubledot slash slash bvlgarian dot tistory dot com slash 138
You can flash the kernels with Odin.
That's great help you can give us.
We are many from outside to buy this YP-GB70 from korea and we need support to improve our device or rearrange it.
Our "little" problem is to find the right connexion or links to the people having knowledge and tools available.
I tried the link you provide us, if right, have a look of what i got.
What item is it to open?
Anyway don't be shy with your english it is better than mine. (french I am)
Regards
I got it after several Trials (bulgarian versus bvlugarian!)
Now I have to dig in the subject. * we keep in touch.
Thanks again,
Hey
Hi, Im a Korean Galaxy Player user.(YP-GB70.)
This Root Knernel is not rooting kernel. Because, This Kernel flashed Odin, device has bricked. But, Korean Galaxy Player's Rooting Rom is appear.
(In fact, This is my custum Rom.)
I tested the "rooted kernel" it leads my device alive from KPH brick gotten after upgrade (I felt Happy). Only problem is it doesn't reconize any internal mémory as well as external SD. So anybody got that?
Anyway, send us link for any other rooting solution. you are welcome.
Korean YP GB70 root and non root kernels (firmware KPL)
Hi folks,
here are root and non root kernels for Korean Samsung Galaxy Player YP GB70. It is flashable only over the last KPL firmware (as of April 2012):
http://bvlgarian.tistory.com/320
Once you flash root kernel via ODIN and set up SUDO, you can flash back to nonroot kernel (apparently the features of root kernel are not very well implemented/maintained anymore). Even if you flash back to nonroot kernel, the device would remain rooted.
---
If you want to flash complete customized ROM for Korean GB70:
http://greenview.tistory.com/31
The *.egg archives can be decompressed by AllZip.
---
And before you start, you can temporarily flash RJ's Custom Kernel r13 for YP-GB70. This kernel has support for ClockworkMod, so you can backup your original KPL ROM to sdcard. After flashing with ODIN you can call ClockworkdMod via combination "HOME button" + "POWER button" + "Vol. Up".
The kernel is here:
http://greenview.tistory.com/attachment/[email protected]
Once you backup your ROM, you should go back to stock kernel, RJ's kernel probably wouldn't boot, it is usable only for backup/restore.
---
Note: if you don't know what you are doing, ie. if you aren't comfortable with fdisk, adb etc., you should expect some major setbacks ;-).
Many thanks for your support.
I still have the following problem to understand and to solve in order to have my device fully working.
Detail:
-When using no rooted kernel it stay in loop at Galaxy player logo for a while....
-When using rooted kernel it starts 100% but I can't access any Sd memory or USB connexion like the internal memory is not adressed.
Who knows about this issue?
Any help is appreciated.

It looks like one or more of your partitions are damaged. Probably by setting a wrong option in ODIN. I've did that mistake and here's how to fix it with a good chance of not losing your data:
* Install root kernel via ODIN
* Start your device normally (do not put your device in DOWNLOAD mode), it's OK if it hangs.
* On your PC install Android SDK + platform tools and make sure your adb is working.
* "adb shell" to your device
* "sudo su" or "su"
* "mount -t tmpfs tmpfs /tmp"
* "exit"
* "exit"
* Get busybox binary: http://www.4shared.com/file/DffR-A0B/busybox.html
* Untar /unzip the binary
* Push the binary to your device: "adb push busybox /tmp/busybox".
Then get fdisk working:
* "adb shell" to your device
* "sudo su" or "su"
* "cd /tmp"
* "chmod 775 busybox"
* "ln -s busybox fdisk"
* "./fdisk /dev/block/mmcblk0"
* List your partitions by pressing "p".
Here's the listing of CORRECT partition sizes (for 16GB model!):
Disk /dev/block/mmcblk0: 15.9 GB, 15925772288 bytes
1 heads, 16 sectors/track, 1944064 cylinders
Units = cylinders of 16 * 512 = 8192 bytes
Device Boot Start End Blocks Id System
/dev/block/mmcblk0p1 5 1944064 15552480 5 Extended
Partition 1 does not end on cylinder boundary
/dev/block/mmcblk0p5 9 40 256 83 Linux
/dev/block/mmcblk0p6 45 76 256 83 Linux

/dev/block/mmcblk0p17 313401 1937720 12994560 83 Linux
If some of them are mismatched (p14 and p15 probably), delete them and create again in fdisk. You don't have to format them, just setup correct type (T 83). Finally write (w) and quit fdisk.
* "sync; sync; sync"
* "reboot"
If the device still hangs:
* Put your device in SYSTEM RECOVERY mode: ("Pwr button" + "Vol up" + "Home button")
* Choose "wipe cache partition"
* Choose "reboot system now"
If the device still hangs:
* Put your device in SYSTEM RECOVERY mode: ("Pwr button" + "Vol up" + "Home button")
* Choose "wipe data/factory reset"
* Choose "reboot system now"
If the device still hangs, then try your service or shop.
Attached what i got with heimdall ytd.

You did a good job! Your model is 32GB by the way, so the size of your partition p17 would be different from my model. Your partition p14 is corrupted and p15-17 are missing. You should delete p14 and create p14-17 as type 83 (Linux). You can make the same sizes, as my example, except for the p17, which you can simply create from block 313401 until the end of the disk . Then try the rest of my instructions.
If the formatting in SYSTEM RECOVERY mode would not help you, you can create tool "mke2fs" the same way you created "fdisk" and you can format the partitions via command:
"./mke2fs -j /dev/block/mmcblk0p14"
That's for partition p14, you should also do that for the rest (p15-17) and then try to format again in SYSTEM RECOVERY.
That should help.
Before correcting the wrong blocks by hand, I innocently accepted the light offer to correct block 14 by typing "w" that's may be not good. but i cann't retur to read dev/block/mmblck0 to see the resulting. What's wrong?
Sorry if bothering for you but that's common problem with beginners!
fdisk
Try: "./fdisk dev/block/mmblck0". What happens?

Great success!
My device restarted after KPL Fw flashing (odin). I have not lost any personal data (photo and music), that's strange after some 20 different flash process and wipes.
Your are top expert guy!
Many THANKS for your help.
I was seeking for solution from end january when I Missrooted my device!
I have in meantime learn so much about Android and also improved my english somehow.
In case I can give you back a service, please ask.
I am sure your problem solving would help many other infortunate guys, why not to make this "sticky".
I can add what is good not to be done to avoid problem then!
Best Regards
Very good! Congratulations Your partitions are correct now. I am sorry you had to wait so long.
trying to fellow the above tutorial with no lcuk , i'm stuck in adb shell error device not found, any clue ?
Hi
In post N°8 You have everything you "must" do.
Rooted kernel is RJ's 14 kernel and nothing else for our device.
You go recovery and adb will connect.
then "shell" et voila.
Forget playing with the PIT file; it si no reason it is wrong at this step, avoid adding a difficulty, please.
Keep informed as you want
now after flashing a Korean kernel the device does boot up normally and everything seems to be fine apart from memory, internal memory and staff is all showing unavailable ?!?! strange situation ?!?! does anybody have an idea about how to fix that ?
Fine,
You mind you are just at a "wipe" step to be done.
Normally full wipe is enough to get the device restarted from home.
OK do it and give me the result reported at the screen after this step.

KEXEC for Sony Xperia Sola

Hallo, after two days of trying to make kexec working, got it working! Its based on hard boot kexec! We can create now multiboot menu and boot multi roms without need for flashing them! Will make this thread updated including files, kernel and instructions!

NO because kernel need enabled kexec and reguire some other modifications whick is not exist on stock kernel!!!
Tried to boot stock kernel but failed, seems not stable kexec by now! Need help!
Here is kernel changes (3 commits by Aug.09.2013) -> https://github.com/munjeni/android_kernel_xperiago/commits/jb-dev seems there is problem with clean reboot! Got kexec working with usind zImage from the same kernel version but seems when there is another kernel version its fail! I think it fail on my reboot function implementation! Need help to solve these things!
Got ansfer by self. Stock kernel and everyother without kexec patch ca not be loaded more info here -> http://forum.xda-developers.com/showthread.php?p=44077327
Tomorow will make it better, hope perfectly working.
Ok, lets go multiboot development!
My experience using kexec:
- since hard reboot owerwrite new kernel and ramdisk, I disabled hard reboot. So we need shutdown cpu instead of using function reboot! Since we have no shutdown cpu function we have very slow boot after executing new kernel and ramdisk (curently I am satisfied with slow boot because kexec can boot new kernel and ramdisk, yes its slow but working )
What is needed for kexec boot:
- kexec can not boot non kexec based kernels
- kexec can boot only kexec enabled kernel which mean only kernel which have my kexec patch (you can patch your kernel using kexec patch from my git)
- suported phones by now is only Sola and Go
My idea for multiboot by now:
- making boot menu based on modified CWM recovery
Modified CWM recovery plan:
- create new recovery and add new sub menu for multiboot feature
CWM multiboot menu idea:
- here we can write kexec multiboot functions
CWM kexec function idea:
- mount system, cache, userdata partition from external sdcard EXT4 partitons and mount them (only if these partions is created by you on your sdcard !!! We can create an small submenu for creating these partitons if these partitons not exist, but not now, we can do it later after creating simple kexec main menu))
- after mounting these partitions we can:
- boot android from allready installed android from these partitions
- ability to install new android to these partiton and boot them
Lets go! Before I start making new CWM, I need better ideas! What you think how we can do it??? Waiting your ideas!!!
Maybe we can do it without using CWM???
So, how about another kernel or rom which isn't supporting kexec yet?

I cannot think of a way to do this without involving CWM. But we could make use of the volume buttons to select the ROM on boot (by mounting the appropriate partition based on the volume button that has been pressed down when the bootsplash screen is displayed). However this would limit us to the number of ROMs that can be installed to two (or max 3, if we have an option to set a default ROM to boot if no button is pressed).
Brilliant work by the way. You are Godlike! :victory:

Simple not supported!
First of all we need to create ramdisk which will boot android located on external sdcard, than if we get it working we can play with kexec. I need your help! If some one get android working from external sdcard than I will continue further. I am allso playing now with new ramdisk and trying to get external android booting!!
Our multiboot is not ready. Only ready is kexec tool and kexec kernel. Our multiboot feature is not yet implemented. Our multiboot is in plan and our multiboot need ideas!
can this be of any help?

Changed fstab, recovery.fstab and sony fstab device paths to point to the external sdcard partition, modified updater_script paths, rebooted to the recovery, installed rom to the external sdcard partitions, rebooted, after abnormaly slow boot system booted but is abnormally unresponsive, so I deleted and reverted back to the emmc boot. Sory guys I am stopping here until some one get android booted from sdcard! I have no free time to play with external boot. When you done it I will continue

a sort of
newer kernels when booting recovery, check if FOTA partition has the custom one installed

Thats good idea, but thats not ideal solution in comparation with phones which have separated recovery/boot partition and bootloader ui like HTC devices which have direct recovery load trought bootloader, these solution only working if primary boot partition is modified and added "few lines" for booting recovery from seccond partition (like ota partition). Will be perfect solution if we make LK bootloader for separating recovery/boot partition, allso with LK we will be able to create custom emmc layout, by now I can not see any small bootloader for NovaThor on google search, seems thats not public. Searching for a way for creating bootloader based on kernel. How we can modify curent kernel and make them bootloader??? We can modify recovery and make them bootloader kexec based, but I am not happy with kexec because we need to fix them first because loading an kernel trought current kexec patch is very slow! I will be happy if some one look into my git and find a solution for fixing them!

My phone has 16mb recovery part but the recovery.img I made is 25 mb so I can't flash it In BoardConfig.mk, I can wrote at least 24.936.448 at the line of BOARD_RECOVERYIMAGE_SIZE to compile the recovery image. How can I solve this problem? Can I reduce the size of the .img file to 16 mb?

I don't understand how you ended up with such a big recovery... The biggest ramdisk I saw (in TWRP) is not more than 4-5 Mb. Do you have a kernel over 20Mb? It can't be, otherwise the stock recovery will be oversized too. Somewhere you made a mistake probably.
And to answer your question, no you can't reduce the size of recovery that big; if you have a kernel compressed in xz, you may try to compress the ramdisk in xz too, and the size will be smaller, but not enough... you need to downsize it with 9Mb, which is not possible.
So check again, to see if there isn't a mistake somewhere.

I took a screenshot of my CM11-0/out/target/product/msm8226/root folder which is 25 mb. There is a boot.img file. I think the problem is that file. I unpacked a few recovery.img files but none of them included that file. If problem is this, how can I remove that file from my ramdisk?
I removed that file and flashed new recovery.img but now my phone isn't booting in recovery mode.

No, for checking recovery root you need to look here: CM11-0/out/target/product/msm8226/recovery/root . But anyway that folder looks strange (I see a perl script there)....
Check my screenshot below.
And type a
Code:
make clobber
before stating a new build, or
Code:
make clean
between repetitive builds.
im getting this error each time i try to compile:
make: *** No rule to make target `/etc/init.rc'

You need to be more specific: what recovery you try to build, in what environment (if it's not cm-11), and post a link to your device folder tree. That error means that the compiler can't find an init.rc file to add in ramdisk.
Compiler stops after a few segments
This is shown in my terminal:
Code:
cp: cannot stat ‘/home/paul/cm-10.2/out/target/product/Ultra/root/init.recovery.*.rc’: No such file or directory
make: [/home/paul/cm-10.2/out/target/product/Ultra/recovery/root.ts] Error 1 (ignored)
mkdir -p /home/paul/cm-10.2/out/target/product/Ultra/recovery/root/system/bin
cp -rf device/CherryMobile/Ultra/recovery/root /home/paul/cm-10.2/out/target/product/Ultra/recovery/
cp: omitting directory ‘device/CherryMobile/Ultra’
make: *** [/home/paul/cm-10.2/out/target/product/Ultra/recovery/root.ts] Error 1
[email protected] ~/cm-10.2 $ make clobber
And you wrote about the problem:
During the build process you may encounter some errors or warnings.
*********************
Code:
Code:
cp: cannot stat `/home/carliv/CM11-0/out/target/product/P780/root/init.recovery.*.rc': No such file or directory
make: [/home/carliv/CM11-0/out/target/product/P780/recovery/root.ts] Error 1 (ignored)
This will not stop the build, and it appears if you don't use a init.recovery.{hardware}.rc file. Can be ignored, as the build process does.
Though in my terminal it just stopped at that part so I had to rename mine which was originally init.recovery.qcom.rc to init.recovery.*.rc
--edit--
And yet it still would not continue ... Any ideas on how to fix this?
--edit # 2--
Here's the pastebin link just in case ->biQ7kjV8 add that to pastebin...(I can't post links)
--edit # 3--
I fixed it... Turns out that it was just a BoardConfig.mk parameter that I forgot to complete
Calculate proper BoardConfig.mk partition sizes
I have this log:
Code:
----- Making recovery image ------

Meaning I have wrong sizes for the partitions so I need help on it...
When I ran the following:

they both return: No such file or directory...
Now If I run the command: cat /proc/partitions
it comes up with this:

Help required for compiling CWM for android 4.4.2 version only?
I am on Ubuntu 14.0.4 and I am trying to build a CWM recovery for Celkon Q 5009android 4.4.2, Broadcom processor). I have set up build environment and currently working on syncing repo. I have heard that it takes too much time and disk space to complete this process. I am interested to know in the following particular scenario : want to build only CWM recovery from source for an android running on version 4.4.2. So do I have to download all repositories or is there any shortcut that would enable me to not download all, but a certain part that is required for android 4.4.2? If yes, how to go about it? please help.
Please help. I do not undertstand why 'repo sync' always fails at a particular stage, though I have 30+ GB of disk space available in my working folder named 'cm12'. Following is the last screen message :
Fetching project platform/external/ant-glob

Now should I run 'repo sync' again or should I use 'repo sync -j1' ?

Hey,
In which size are the values in BoardConfig.mk at BOARD_BOOTIMAGE_PARTITION_ZISE? bit?
And how I can convert blocks to this size because my lge only print out the partition sizes in blocks.

Somewhere around that post you will find your answer.
Hi. Your guide is the most useful I found on the net. Much more than the official cyanogenmod wiki's porting one. Thanks a lot.
I'm trying to use it to build a cm 12.1 (lollipop) cwm on a mediatek device.
1) My stock rom (also Android 5.1) already ships a fstab.mt6795 file into the ramdisk. I moved it inside /recovery/root, and copied its content in /recovery/recovery.fstab
This is its content, should I make any change inside it?
Code:
# Android fstab file.
#<src> <mnt_point> <type> <mnt_flags and options> <fs_mgr_flags>
# The filesystem that contains the filesystem checker binary (typically /system) cannot
# specify MF_CHECK, and must come before any filesystems that do specify MF_CHECK

3) My stock rom obviously already ships a init.mt6795.rc. Should I merge any of its lines to the one I copied from /bootable/recovery/etc in my /recovery folder?
Thanks in advance for your time and your efforts.

First let me ask you where did you find a cwm for lollipop to build it? I'm interested to see that.
Second in recovery fstab you may want to add emmc partitions like boot, recovery... Check my github and look at elephone p6000 device folder (it's close enough to understand). If internal sdcard is on data/media you don't have to add it at all in fstab (at least that was the rule for kitkat... again I need to see the source for that lollipop cwm to tell you exactly). In elephone device recovery fstab you can see that usb and external sdcard are defined as auto for type not vfat because it is better to let minivold manage that.
Normaly for cm12.1 ther is no need to copy any rc file in root, only the fstab. {hardware}, which you said you did.
Again I can tell more if I will see the source code for the recovery, and last thing my guide is quite old now but I'm glad you found it useful.
Thanks for your quick reply.
I think I've not been so clear explaining what I'm doing: when I talk about "Lollipo CWM" I just mean that I'm working on 12.1 branch of cyanogenmod source tree, that as you know is based on the same sources of Lollipop, instead of the one the guide was originally aimed to.
1) I feel really dumb at this moment. I don't know exactly how many time I read that fstab file, and I never noticed that it lacks entries for partitions not managed by stock recovery. Sorry if I wasted your time with a stupid question.
2)For sdcards, then it's better to leave untouched the voldmanaged options, but change the filesystem type to auto?
3) I don't need to copy any other .rc file (init.mt6795.usb.rc, init.xlog.rc, etc...), nor to merge anything from init.mt6795.rc of the stock rom. Right?
Thanks again.

I did understand it's cm12.1, but that was my question since there is no cwm for cm12.1 only cyanogenmod recovery which is different. At the moment I only recommend twrp for cm12.1+ and for that you have to use a different fstab, easy to find on github or here on xda in twrp threads.
Then, if I'm not too much confused:
- since CM12, Clockworkmod isn't anymore included in its source tree
- if I don't set any RECOVERY_VARIANT it defaults to CyanogenMod Recovery, not CWM anymore
- the recovery.img I built is, at its best, a Cyanogenmod recovery
- the recovery.fstab I used (the one i posted before, but now with /boot, /recovery and /nvram entries added) is in version 2 format, that twrp doesn't understand. So I have to find out how to convert in the old fstab format.
Am I right?
Another question: I used the last version of your CarlivKitchen. That doesn't offer anymore the choice to re/pack for standard android or for mtk images, because it automatically detect the format. But when it repacks, it adds the mtk header if the original image had it? Or am I forced to use a custom boot image maker?

Yes for all and for twrp fstab I think you can study device folders from twrp github (few are mediatek).
My kitchen now detects if image has mtk header and will repack it the same way (it stores a variable in unpacked folder which will tell that it must add a mtk header).
I decided to follow this guide to integrate the changes needed to build twrp instead of cwm: http://forum.xda-developers.com/showthread.php?t=1943625
It doesn't cover all the preparation steps like yours do. Do you think there are changes to be made to make your guide suitable for cm12 and twrp, or I can follow it until the " Build a CWM-based Recovery " paragraph?

[Q] Update Kernel to support LagFix (TRIM)

Hi all!
I have been using Quarx's CM9 for Allwinner A10 on my LY F1 clone for many years now.
I can't even remember the last time I formatted it!
Even without any significant no. of apps installed, the tablet now lags like hell for simple tasks like bringing up keyboard, typing from keyboard, etc.
I started searching online for the cause for this lag and I found this:
http://www.makeuseof.com/tag/how-to-fix-androids-bad-performance-and-awful-design/
So I thought, maybe since CM9 is ICS 4.0.4 based, maybe because my tablet's internal memory is not TRIMmed, my tablet has become slow.
I installed Lagfix from Google Play, but it said that:
Code:
TRIM is not supported!
TRIM is not supported on the following partitions:
/data, /cache
This is either hardware or kernel issue and cannot be worked around.
The code in the background read like so:
Code:
#fstrim -v /data
fstrim: FSTRIM Operation is not supported on transport endpoint
#fstrim -v /cache
fstrim: FSTRIM Operation is not supported on transport endpoint
I carefully took apart the back cover of the tablet and found the NAND FLASH chip which was:
Micron NAND Flash 29F64G08CBAAA
This tablet has 8GB internal memory and that Micron flash chip seems to be the internal memory cause the rest of the chips seemed to be Hynix RAM chips (This device has 512 MB RAM)
After searching for data sheet of the Micron NAND flash chip, I found it, but could not confirm if ti supports TRIM or not.
I also found the following link:
http://www.techpowerup.com/reviews/ocz/synapse_60_gb/
The SSD seems to have the same chip, but if you see in the table, it says TRIM supported so I strongly believe that this is not a hardware issue.
Which leaves us with only one option: Kernel issue and this is why I am posting here:
How to upgrade CM9 kernel to one that supports FSTRIM?
Here are details of the ROM I have installed:
Android version: 4.0.4
Kernel version: [email protected] #2 Fri Apr 13 19:01:51 CST 2012
CyanogenMod version: 9-20120623-NIGHTLY-a10
Build date: Sat Jun 23 18:27:35 OMST 2012
Build number: cm_a10-userdebug 4.0.4 IMM76L eng.quarx.20120623_Seby-port
Please note that I am completely happy with the ROM except for the lag and I want to try to fix the lag instead of flashing it and starting over.
Thanks for your time!

[REPARTITION] Nexus 7 (2013) Repartition [FLO/DEB] [16GB/32GB] [UA TWRP]

Nexus 7 (2013) Repartition​
No one is responsible for your actions except yourself. Everything written further may potentially brick your device, although risk is reduced to minimum.
This repartition package offers 1.5G /system; a /vendor partition and it is fully backward compatible with any ROM (including stock system.img).
Known-issues
HTML:
- If repartition pack says that device isn't correct,
than, if partition table wasn't modified before,
congrats! your device has different memory chip
that those I worked with. No worry, PM me and
I'll add support for it.
DO THE BACKUPs. Repartition will erase all your data
USB connection to PC is MANDATORY else you will not have opportunity to push ROM to your device
Backup
# Before processing further we highly recommend you backup persist and EFS using adb
# Or you might lose your IMEI/WIFI + BT mac addresses
Code:
adb root
adb shell
dd if=/dev/block/mmcblk0p2 of=/sdcard/modemst1.img
dd if=/dev/block/mmcblk0p3 of=/sdcard/modemst2.img
dd if=/dev/block/mmcblk0p4 of=/sdcard/persist.img
Now you can find 3 *.img files at path /sdcard. Copy them to your PC since internal memory will be erased.
Installation
HTML:
# This mod is backwards compatible with any ROM so we highly recommend NOT to reverse it if repartition went well.
# You should use ONLY recovery from this thread since other don't support all benefits of this mod.
# When installing ROM just after you flashed zip and before installing GAPPs you MUST make a resize in TWRP since all roms are build for ~800M system.
# Package is unified for flo and deb. To restore stock layout use same zip and steps as for repartition.
1. Boot into recovery (You need to allow system partition modification to be able resize /system in recovery).
2. Backup your data & Move your files from flash to your PC.
3. Flash repartition pack zip.
4. Do the actions asked by repartition pack (go to Terminal in ordinary recovery and input word that pack will tell you. Everything else will be done automatically).
5. Phone will reboot into recovery.
6. Install TWRP from below (it is build with support of new partitions layout and sizes. It can be differed from official TWRP by next format 3.x.x-1 UA).
7. Format everything. (mount errors will not affect formatting!)
- In TWRP: Wipe > Format data
- Type yes
- Once this completes go to: Wipe > Advanced Wipe
- Tick all the boxes and wipe. There should be no further mount errors. (Thanks [user=7694808]@mr_rubbish[/user] for corrections in formatting).
8. Install ROM which you like.
9. Enjoy better flash partition layout.
If something gone wrong - we recommend you NOT to do anything by yourself. Write here for help, else you may do only worse.

Common issues and F. A. Q.
Repartition pack should be safe for most devices. Common mistakes, issues and their solution will be published here.
1. You shouldn't flash any internal parts of repartition pack (*.sh files) only flash whole zip using TWRP. You may use my scripts for personal use or projects but authorship should to be kept.
2. If something isn't mounting after repartition try to format partitions that don't mount using Wipe -> Advanced Wipe in TWPR. Ideally you should format in that way all partitions in Advanced Wipe menu (see 5-th step of installation guide).
3. If you want to be sure that repartition went well I enclose loging zip. Flash it after repartition (when device reboots into TWRP). It won't modify anything only generates a partition.log in root of internal storage and outputs your current partition layout to screen. You should check if your layout is same as those fragments I provide under spoiler (file systems doesn't matter). If there are any differences you have to describe what you did and enclose partition.log to your post.

4. After flashing most ROMs system size will reduce to stock, you need to resize /system in TWRP or use flashable resize zip for ROMs that support addon.d (automatic resize when dirty flashing updates).
5. After returning to stock partition table you won't be able to get into the Recovery from the bootloader anymore, but when you start the tablet normally it goes straight in the Recovery. It is normal state. New partition table proposes larger /recovery size (16MB) while stock gives only 10MB. During restoring stock process, it is impossible to restore larger recovery backup into new smaller partition. Whether not to leave user without recovery excess, recovery backup restores into /boot partition. Just flash ordinary TWRP and install ROMs from it.
6. Don't install the zip file from the USB OTG. Copy them into the /sdcard. Else you will get message after flashing repartition pack.
Code:
"Can not extract updater-script. Do you have it in package?
Updating partition details...
...done"
Link not working for the repartitioning package...
@rlw6534 should be fine now
Any chance you give details on backing up persist and EFS with dd command? I'm not really a noob but I also don't want to mess up my tab...
@rlw6534 You actually should't brake anything. Added an instruction how to backup EFS and persist.
OK. Tried to flash on a clean, freshly wiped system (Flo 32G), all stock, ext4 on cache and Data, TWRP 3.2.3-0. Got the following:
******Applying dark magic******
This is not a Nexus 7 (2013)
Updater process ended with ERROR: 1
How to restore files, that we copied from our tablet using dd command ? (I haven't done anything yet. Just asking)

@rlw6534 your partition table was modified.
@MikiGry same commands, just switch paths.

Do you mean that despite this error message:

The partition table has been modified correctly?
@lollyjay No it wasnt. Package has 2 step security system. It checks if partition table was modified and in what way (by package itself, by user or it is stock). Second step is that package itself doesn't modify anything, it needs manual confirmation in terminal, else no changes will be applied.

So do I NOT flash the modded twrp first?
Your instructions said to flash it after reboot to recovery
@lollyjay actually it shouldn't metter, but after would be better

I'm going to do this when I get home. This might mean that flo/deb will get Android 9 Pie
@lollyjay look through UA ROM thread I wrote there about P on flo/deb

I have previously used sysrepart.zip and sysrepartundo.zip from this thread, although not recently:
https://forum.xda-developers.com/showpost.php?p=76278047&postcount=19
I returned it to stock a while back (827MB). Perhaps I need to sgdisk a stock partition table?
@rlw6534 Every manual repartition or repartition made not by my pack needs an individual look and partition table restore.

OK. Here is my partition layout. My userdata appears to be smaller than stock, but there isn't enough room on mmcblk0 to increase it to the size that your script is looking for. I have no idea how that could have been changed without bricking the tab. Everything else looks normal. Ideas?
