[REPARTITION] Nexus 5 Repartition [HAMMERHEAD] [16GB/32GB] [UA TWRP]

[Clamor]

Nexus 5 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

- 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

Installation

# Before processing further we highly recommend you backup persist using terminal and dd comand and EFS
# Or you might lose your IMEI/WIFI + BT mac addresses

# 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 ~1G system.
# 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.
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. 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 shoud 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 discribe what you did and enclose partition.log to your post.

4. Flashable resize zip for ROMs that support addon.d (automatic resize when dirty flashing updates).

5. To backup persist partition you need PC with installed adb. Boot your hammerhead in TWRP and plug to PC. Than use next commands.

adb root
adb shell
dd if=/dev/block/mmcblk0p16 of=/sdcard/persist.img

Than copy .img file from root of internal storage to your PC. Although, script doesn't affect that area, backup of this partition may help in case of any problems with mac address etc.

Thank you for this zip!!! It works fine but I used nano package gapps for the face unlock but still does not work on LOS 15.1. Any suggestions

 

[getrooted0019]

Vendor partition means support for treble.... Right?

---------- Post added at 04:11 AM ---------- Previous post was at 03:44 AM ----------

After flashing a ROM the system partition resizes back to 1009mb...
Can this be fixed?

 

[Clamor]

@sinkoo1979 try bigger gapps, alse, it may be Lineage problem.
@getrooted0019 you didn't read Installation part carefully, did you? You need to use resize option in TWRP to restore original size after flashing ROMs since they are build for 1G /system partition.

 

[sinkoo1979]

getting a message in twrp "this is not a nexus 5" and won't let me switch back to stock.

 

[Clamor]

@sinkoo1979 send me your partition table in bytes

 

[sinkoo1979]

@sinkoo1979 send me your partition table in bytes

Data and vendor partitions in my nexus 5 are 0mb and not present. System showing about 1028mb while cache is on 29mb.
Thank you for your help but can't change the cache storage back to stock. Can't access the internal storage in TWRP. I think I corrupted my partitions on the nexus 5. Nexus 5 boots into TWRP but can't access nothing. Tried to flash different rom with OTG but bootloops. Can't flash stock because the cache partition is too small.

@sinkoo1979 just stop. I'd ask you to create a telegram account and PM it to me here. I'll help you, just don't do anything

This is fixable! I was a noob and didn't resize my system partition after flashing rom. Flashed the hh repartition to go back to stock in the ua twrp and got a bunch of errors. Then flashed stock recovery and tried again. This is not a Nexus 5 popped up. The backup file is inside the flashable zip. I just used adb shell and parted to execute the commands listed in backup and viola my Nexus 5 is back. So those freaking out that they messed up their phone...don't worry it's fixable just listen to Clamor. Anyone can pm me too if you need help.

 

[Clamor]

@typow102 if repartition pack says "It is not Nexus 5" than you shouldn't continue without asking here. Using scripts from pack on them own is dangerous as well. Currently I don't know how many types of MMC installed in our Nexus 5 and "It is not Nexus 5" on repartition or on returning to stock may indicate a new type MMC chip like it was with Nexus 7 (2013)

That's the thing though It worked perfectly the first time I flashed it. No errors. Luckily I have had quite a bit of experience with terminal and parted so I felt confident in what I was doing. Can I help you in any way with this? There very well maybe a different mmc chip we don't know about yet.

 

[Clamor]

@typow102 feel free to help if you are certain you can.

 

[Clamor]

For those who downloaded repartition pack before this message is published, please redownload pack since previous version might have a problems with repartition. If repartition was already made, don't worry everything should be fine. Just use up-to-date pack.

 

[bagajohny]

Do I need to resize the partition in twrp every time after flashing any ROM and then flash gapps package?

 

[Clamor]

@bagajohny yeah, till devs decide to support it officially.

 

[froilson]

When I install the ROM (crDroid 4.6) after change the partitions, when I go to TWRP, Wipe > Advanced Wipe, selecting system and pushing over Repair or Change File System button and then over Resize File System, this message was shown:
Repairing system before resizing.
Repairing system using e2fsck...
Done.
Resizing...
/sbin/resize2fs /dev/block/mmcblk0p25 process ended with ERROR: 1
Unable to resize system.
So no resizing is made.

 

[Clamor]

@froilson resize once more, if fails, change mounting state of system and try once more

 

[M Asad Khilji]

@Clamor with this can we have treble support ?
