D620R Stuck on TWRP | flashing last forever - LG G2 Mini

Hi,
I've rooted my D620R, unlocked the bootloader and installed TWRP recovery. TWRP works fine. Next I have changed the partition table to "optimal". All 3 partitions were properly mounted after the reboot. Then I tried to flash CM 13 and it seems stuck forever on flashing. I've checked that file is not damaged:
Code:
# sha1sum /sdcard/cm-13.0-20160120-NIGHTLY-g2m.zip
97f55ce7488f2906d868e88537e5a3cdb5058347 /sdcard/cm-13.0-20160120-NIGHTLY-g2m.zip
top shows working process of updater
Code:
/tmp/updater 3 17 /sdcard/cm-13.0-20160120-NIGHTLY-g
Screenshot of TWRP working at cieniek.pl/Screenshot_1970-01-01-13-58-15.png (can't attach it directly).
Any advice?

I believe that CM13 needs the stock partition table, but I am not sure.

You have pointed me towards right direction with that partition table, as it was the problem. "Optimal" partition table is fine, but mine was slightly too small. I have adjusted it and now it works.
Thank you.

DISCLAIMER!
Operations on phone’s partition could be EXTREMALY dangerous.
As You surely expect - I take no resposibility if something will go... not as it supposed to. The responsibility for potential damages caused by using this guide is Yours, and Yours only!
New system partition scheme is “designed” for custom ROMs NOT based on original Samsung firmwares (because of it’s size and using /preload partition, which we intend to extremely resize), to name just a few reasons).​
The method of modification is created by @Tesla-MADAL93 from Galaxy Advance sub-forum, all credits should go to him!!! He spend many hours using trials and errors method to achieve final success.
Part ONE: Preparations / theory.
1.Procedure requires any Linux distro with usb connection configured (tested on Ubuntu 12.04 LTS).
2.Working ADB (android debug bridge) – you don’t need to install whole ADK, just adb file with correct path added.
[EDIT/CAUTION]You can use Windows with adb configured, as proven by @maxprzemo, but I wasn’t tested by author of this guide!
3.It is strongly recommended to make a backup of your apps and data before start (using titanium backup or simipar app) Restoring nandroid backup will destroy your new partitions, so don’t use it!!!
4.With this method “safe partiotions” of phone’s eMMC memory are being removed and recreated „safe” using „parted” command in adb shell mode. Some partitions are extremely decreased, one is totally deleted. And the most important – partition of your choice will be expanded. Example displayed below sets internal (DATA) partition as large as possible (almost).
5.You will need external micro SD card after remodelling partitions)
6.Memory swap (SD0 and SD1) required BEFORE first start of your chosen ROM!!!
7.You can restore original partition scheme using Heimdall or Odin (not tested by me, problems with Odin reported by the author of whole modification) with repartition selected.
8.Partition numbers and names are very important (crucial), so we need to create them correctly, setting beginning and the end of each one very carefully.
9.Last important thing! I use minimal gapps pack for every ROM. I didn’t tested if full gapss fit on new /system partition! You’ll have to check it by yourself!
Default partitions and sizes are displayed here:
​With this guide you will achieve something like this:
[Side Note: this is just an example – you can make internal card (UMS partition) bigger, leaving /DATA partition intact, just to install bigger games – you’ll have to calculate your own values]
Part TWO: Repartition
OK., let’s do it! You have to perform all steps EXACTLY in described order!
1.Turn phone on in recovery mode, connect it to computer using usb cable.
2.Open terminal / console (Ctrl+Alt+T)
2a. Enter command:
Code:
adb devices
You should see device connected (some numbers and letters)
3.Write (press enter after each command):
Code:
adb shell
su
parted /dev/block/mmcblk0
unit kb
print
You should see default partition scheme (just as one first screen above)
OK., say goodbye to your old partitions. Deleting other partitions could (and probably – will) have irreversible consequences!!
Now we will delete partitions, starting from the last one:
Code:
rm 8
rm 11
rm 9
rm 4
Now you will encounter some error – despite of the unmounting partitions before abovementioned procedure - /cache partition is now mounted. Do not unplug phone, just enter “mount and storage” submenu in recovery, and unmount cache partition)
So let’s continue:
Code:
rm 4
rm 5
rm 3
You just deleted all “safe” partitions, enter to check this:
Code:
print
OK., it’s time to (re)create!
(SYSTEM, partition 3)
Code:
mkpart primary 105906 525906
(CACHEFS, partition 4)
Code:
mkpart primary 3848809 3948809
(DATAFS, partition 5)
Code:
mkpart primary 525906 3848809
(UMS, partition 8)
Code:
mkpart primary 3948873 3948937
(HIDDEN, partition 9)
Code:
mkpart primary 3948809 3948873
Let’s rename them properly (probably you can do it in one mkpart command, but it doesn’t matter):
Code:
name 3 SYSTEM
name 4 CACHEFS
name 5 DATAFS
name 8 UMS
name 9 HIDDEN
Almost done, let’s check:
Code:
print
Nice? Of course it’s nice!!! )
One last thing – we have to make our magic /preload (HIDDEN) partition visible for phone [it won’t boot without it!!] Because recovery won’t format it properly, lets use parted command for a last time (wait after each command):
Code:
mkfs
y
9
ext2
Now you can unplug the phone and format (in recovery) partitions:
/system
/data
/cache
OK, as I said before – you’ll have to switch storages BEFORE using phone again.
For now – you will have to manage it by yourself, just to make it short:
-for 4.2.x ROMs you can use modified vold.fstab file
-for 4.3.x ROMs – you have to manually modify build.prop, or use available zip package that will do it for you (that method is supposed to work with 4.2.x ROMs, but I didn’t test it!)
-I never used any of 4.4.x ROMs, but as I heard, there is method for switching memories too.
WARNING!
I didn’t test the way back to original partition sizes! It was tested by tesla-Madal93 though…
Sometimes (when transfer ring from one android version ROM to other, or using some old version where /preload partition was set as SWAP) you will need manualny format HIDDEN partition, just as shown above:
in adb shell mode:
Code:
parted /dev/block/mmcblk0
Code:
mkfs
y
9
ext2
FINAL WORD: If you are not sure – DON’T DO IT!!!
Screenshots are broken... I assume this deletes the "USB storage"? If then, you and the OP are bosses :good:
I can see the pictures (but are linked from other forum, i'll switch them in future), but yes - it deletes usb storage (ok, not really - new usb storage has 64KB and doesn't have to be even formatted)
Good job !:good:
Personaly i wont do it ever because 1,2 GB is enough, and if i get over that surely i have something on phone that i need to delete because i am not using it
Great post.
I would love to see the same mkpart commands to recover the preload partition space and allocate it to the data partition.
I'll do the full repartitioning thing when the team canjica CM11 major bugs have been solved. I'm not too confident about the other cm11's memory swap sustainability over time

I don't know if I can make something as a simple script for recovery (maybe with busybox), but for Linux yes (to automate repartition process). In every case, I will tell/send it to @judas1977 that will provide to update this guide.
@judas1977: Nice work

Made under windows 7
Well done judas77 and Tesla-MADAL93 :laugh:
I'll try to make (semi)automate script for linux terminal in couple of days (unless @Tesla-MADAL93 make this) - then we can have/prepare separate scripts for various partition sizes:
- bigger /DATA
- bigger /UMS (like @maxprzemo did)
- etc...

/cache 8M (assuming dalvik.vm.dexopt-data-only=1 && dalvik.vm.dexopt-cache-only=0) (2MB margin)
/data 350M (assuming about 100M of actual usable app space) (20MB margin) -- in practice less than 600 will be quite tight
/sdcard 1M (depends on apps again and FAT fragments easily by design, avoid less than 100M)
Now what should be nice having are ROM variants with internal storage disabled, so that we can remove partition 8 and both bypass the need for storage swapping but also avoid some apps not desiged for 2 "SDs" getting partially broken
I just repartitioned my phone, but acidentally I partitioned partition 2 instead of 3 :/
Now when I try to rename the partition 2 again in "Modem FS" with the name command, it only names the partition as "Modem". Can someone explain me please how to rename it to the original name again?
Thank you

I restored my old nv_backup and now the device is booting... Let's see if it will work. I'm just confused, because in recovery the partition is called modemfs and when restoring nv backup it is called Modemfs....

Impossible (well, without LVM or something) because there's USB storage in the middle... but with 10 minutes and a calculator you can create your partition sizes relatively easily
If I'll make the following changes in partitions: UMS resize to 400MB, CACHEFS resize to 30MB, DATAFS resize to 2,313GB, Fota 0 MB and I'll leave SYSTEM and HIDDEN to default sizes can I restore CWM Recovery backup or flash stock rom with Odin?
The HIDDEN partition will have the same size, but the location on mmc is different, as you can see below.

Nandroid: I wouldn't personally do it but it should work
Odin: definitely repartition with PIT and full image first
And be sure to input the partitions in numerical order!
You can make a script? For linux and winzozz?

Don't make CACHEFS partition under a minimum 100 MB!!!
In this partition is stored system apps' dalvik cache on all CM and CM-based ROMs, if available space is insufficient to store dalvik cache of all system apps the ROM isn't stable and has lot of FCs depending on what caches are not stored. If you want to go under 100 MB (that I advice) first check actual used space on this partition with Partition Table (available on Play Store) on your ROM, remember that every ROM has its system-dalvik cache size depending from apps' classes.dex

And why?
I've had zero problems in Android with 10 MB as long as you keep dalvik-cache away from it ( dalvik.vm.dexopt-data-only=1 and …cache-only=0)
Recovery probably uses it more though...

cant modify ANY parttions - I want to totally ZAP the flash

I have a NOOK tablet 16GB that is somehow locked from modifying partitions
I have tried
the repart image , which has worked many times for me in the past
the AdamOutler Ubuntu Disk
formatting / wiping options in various versions of CWM and TWRP
fastboot erases
fastboot formats
dd'ing /zero to various partitions
parted
sgdisk
a zillion scripts
something at a low level is preventing modifications to the partitions
Im wasting far too much time on this , but I hate being beat (-:
I have a backup of rom and factory , and dd images of stock parttions so I am 100% comfortable with something that
will COMPLETELY ZAP the device
if I boot a known good CM10 image from SD card, it fails to boot , I was assuming if I could get a running android from the card, I'd have access to lots of tools... , but it just fails to tun CM10
any help appreciated.
Thanks
To completely zap the device, erase the partition table. That will leave you one, giant, unallocated space.
From there, you need to recreate all partitions from scratch.
You will not be able to boot without a bootable CWM SD, so have that handy.

Thanks for responding, Yes, I have tried multiple ways to to zap the table and it doesnt stick.
sgdisk -Z, sgdisk -z parted,
no matter what I do the partitions remain untouched.
I reboot and it still boots into an old stock OS that has a FC shortly after startup, and the internal recovery (factory) , which I can not overwrite, gives the please restart and try again message.
hmm,
I WAS able to get a CM7 SD card image to boot and run
appears to work "normally" , but Internal storage shows as "not available" in settings

You're supposed to do:

That will for sure give you an empty partition table. You probably forgot to write the changes before exiting.

[Q] How to repartition internal memory

Is there any way to re-partition ROM eMMC ? since /cache has 500 MB ,it can be re - partitioned to merge into /data partition . so any body here know how to re-partition ROM ? is it possible ?

Since the "important" partitions are towards the end, something can well be done (as long as you have full OS installation media in zip or nandroid format, plus some tools which may not even be needed on this phone)... If you can wait a week I'll try to write a guide
After some testing, it appears to be impossible, like there is some S-ON on the partition table area...
full partition table needed please..

[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.

...
30 2348843008B 2610987007B 262144000B vendor
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"

@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:
******Applying dark magic******
This is not a Nexus 7 (2013)
Updater process ended with ERROR: 1
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?
