I have an E2303 with 8 GB and tried to re-partition the internal memory to obtain more space for apps. I followed the instructions in the video but when I reached the point to re-format the modified partitions with mke2fs I got the following error:

CANNOT LINK EXECUTABLE "mke2fs": library "libext2_misc.so" not found​

Is there any solution to this?

I just flashed it on my m4 aqua E2303 an it works fine. I had an issue with wifi, but I fixed it by changing the boot.img(skyMelon) v8 for v9(download it from the internet) in the zip file and flashed it again and now the wifi is working too.

try to wipe your phone that might help and try to flash again.

my phone, sony xperia m4 acqua E2303 is stucking at loading. i flashed the rom with twrp.

help please
[Sony Xperia M4 Aqua] Axaroid:
happened to me, don't wipe cache and davlik cache before flashing, wipe it after flashing the rom and if you are stuck at boot then power off the phone from a hole in micro sd card slot, insert a pin in the hole and hold the button inside it for a while then reboot again

[Sony Xperia M4 Aqua] Gray47Maxx:
We were looking for the solution for you. There may be 3 reasons why did you get bootloop:

1. There's a problem in our zip (maybe it's just meant to be used only with 8GB, but then why did it work for my colleague's 2333?), and that's a question to [MENTION=6786415]kamilkos16[/MENTION]

2. You're doing something wrong (maybe you haven't clear the cache after flashing or you're not in a last stock ROM)

3. There's a bug in a stock ROM which leads you to that problem.

You can contact me and Kamil in Telegram's AOSP news chat - It'll be easy for all of us. The link is https://t.me/joinchat/DcjlQ0M_vd9mM217vFjPmw
[Sony Xperia M4 Aqua] cirnocirno:
Have you fixed it?

If you haven't, I suggest you download Sony Companion Software

Go to support zone and click on REPAIR DEVICE, follow the instructions and you should be technically good to go.
[Sony Xperia M4 Aqua] bozinsky73:
no way to make phone boots following the full procedure..

stock rom: 26.3.A.1.33 / R6C

no errors given, just stuck on ANDROID bootanimation for hours.

what I did:

- clean flash last tft rom

- reboot and set up

- root and install recovery

- reboot

- clean cache and dalvik

- flash patch reduce

- clean caches

- resize partitions (full procedure)

- clean caches

- flash AOSP archive

- clean caches and reboot

- stuck!

any suggestion will be appreciated :)

BoZ
[Sony Xperia M4 Aqua] Gray47Maxx:
Hmm, let's think what can cause bootloop:

1. What is your model?

2. Have you recovered your data after resizing?

3. Have you checked if you did everything correctly while you've been resizing partitions?

Have you updated your apps?
[Sony Xperia M4 Aqua] bozinsky73:
1. Model is 2303

2. Of course I did recovering data and system

3. i've copy pasted all commands into adb shell so they are ok

when I firstly boot the untouched system, just to set android up, I did not update system or google apps, so they where the same as into the original TFT to patch/reduce

EDIT:

going to try the whole process with a differents recovery and SuperSU binary..

EDIT 2:

reflashed, repatched and re-everything...

but still no way to exit the bootloop.

in the OP there's a link to a zip file, which is a tread... https://xdaforums.com/showthread.php?t=1929852 where I can find different busybox installation zip and a link cleaner for busybox.

which one do I have to chose?

thanks again
[Sony Xperia M4 Aqua] Gray47Maxx:
That's very strange. The author (which is too lazy to answer you) says that "it can be career related, it's the only possible reason". He also had 2303 (before he deleted BL), and it worked fine for him, so... It can be only FTF-related, AFAIK.

BusyBox-v1.24.2-Stericson.zip. I think it'll work.
[Sony Xperia M4 Aqua] bozinsky73:
Thank u very much for the fast replay!

And greetings to the Author, that I'm sure is not lazy but only very busy :good:

I'll try with a different tft asap and immediatly replay.

(by the way, this phone wont allow flashing other system.img file via ADB from other roms... even after a FULLwipe... even if bootloader is properly unlocked)
[Sony Xperia M4 Aqua] Gray47Maxx:
Nah, he's lazy)))

Also, does it work?
[Sony Xperia M4 Aqua] bozinsky73:
Tried another italian rom, but no way :(

Can you please suggest the right tft to download?

Thanks again :good:
[Sony Xperia M4 Aqua] Gray47Maxx:
Try something generic (like Customized GEL or Customized RU) :^)
[Sony Xperia M4 Aqua] bozinsky73:
it always ends up in a bootloop :-/

Vhy467CGYH%466, for me it was when I flashed, lounched everything and then drained the battery to 0. After recharging and trying to turn on it is stuck at rolling gear.

The only thin is to reflash the rom without any clearing.

Try to flash different kernels.

i think i just bricked my phone :'(

pls help

i use e2363

i was at step 6 when. i typed /external_sd/parted /dev/block/mmcblk0 as instructed and adb didnt recognise the command.

i went back and selected sdcard as storage and typed step 6 again and it was recognised so i typed step 7

7. Now you have to type in one by one:

rm 30

rm 29

mkpart primary 742 6142

after i pressed enter i got error too many partitions or something retyped a lot and no avail i tried to restart recovery to start afresh but now my phone wont respond at all. even if i plugged usb no response at all. even it wont charge. i removed sdcard samething no response at all.

pls help.
[Sony Xperia M4 Aqua] Gray47Maxx:
That's the point. The instructions says that the next steps are only for 8GB users. And, as far as I know, 2363 is 16GB model. So... If you still can launch TWRP - I think you can fix this :^)
[Sony Xperia M4 Aqua] passionicon:

Hello. I have done everything exactly like in the tutorial, but it just stays in the ANDROID screen forever. Any help? I have even installed the busybox zip.
[Sony Xperia M4 Aqua] Gray47Maxx:
First of all: have you tried to install Concept-ify over PexoROM?

And 2363 is 16GB!
[Sony Xperia M4 Aqua] passionicon:
like i said i am currently bricked, phone wont charge or come on its totally blank. wont enter flashmode or fastboot mode. complete blackout. i tried to install it on pexo rom and it led to this problem

check this link; its 8gb and from personal use its 8gb http://pdadb.net/index.php?m=device&id=7953&c=sony_xperia_m4_aqua_dual_lte_e2363__sony_tulip_ds
[Sony Xperia M4 Aqua] Gray47Maxx:
That's very strange. The white papers (from Sony) says that this is 16GB model. Are you sure that your model is 2363? Have you flashed ROMs from the 8GB (2303, 2306, 2312) versions?
[Sony Xperia M4 Aqua] passionicon:
i have only ever flashed pexo rom on the device. what do i do now? phone still currently down. yep my model is e2363 and its 8gb rom.
[Sony Xperia M4 Aqua] Gray47Maxx:
Impossible... Probably, your phone was somehow reflashed to a ROM for a 8GB users, or your phone isn't 2363.

Anyways, now your phone is completely bricked. Can you get into Flashmode/Fastboot mode?
[Sony Xperia M4 Aqua] passionicon:
no i cant get to flashmode or fastboot mode
[Sony Xperia M4 Aqua] Gray47Maxx:
Then it can be three things:

1. EMMC started to die before doing Concept-ify (that's why your phone was 8GB), and died after partition changing... Most likely.

2. You've messed up with bootloader (Kamil did the same too, his BL isn't with him anymore).

3. You've messed up with partitions table (like I did, but luckily I've had TWRP, so I've partially recovered)

If you can't get into TWRP, you can do two things:

1. Get to the Sony's Repair Centre and ask them for help

2. Throw it into the nearest bin, buy something new (Xiaomi, Pixel/Nexus, something with bunch of fully working ROMs) and be happy :^)

[Sony Xperia M4 Aqua] flaximuss:
Hi guys,

I tried me too your ROM unsuccessfully, even if I tried and repeated twice your steps to be sure, it doesn't work.

My phone is a E2333, here my steps :

- Flash with official .ftf from xperifirm (GENERIC_26.3.B.1.33_R5C)

- Reboot, Android not configured at all, shutdown, reboot in fastboot mode

- Root procedure TWRP, wipe caches

- Reboot in recovery mode, install MM ROM, wipe caches

- Reboot, Android Logo turn and turn..., force stop after 10mn

- Reboot in Recovery mode, install Busybox Stericson v1.24.2, wipe caches

- Reboot, Android Logo turn and turn...again, force stop after 10mn

Any ideas?

Thanks in advance
[Sony Xperia M4 Aqua] Gray47Maxx:
No. PexoROM can't be used as a base to ANY STABLE ROM. Because of their deep system patches. Only stock, only hardcore)))
[Sony Xperia M4 Aqua] Gray47Maxx:
You must install only the patches to make it work. Just a disclaimer, so you'll not break your phone)))

Wait, you've installed your ROM twice?
[Sony Xperia M4 Aqua] flaximuss:
:D

No, for MM ROM I meant : Concept-ify - the improved MM ROM (with AOSP pack) which means : M4_PATCH_REDUCE.zip

;)
[Sony Xperia M4 Aqua] nzdge0:
Hi, I have just finished installing this rom on my E2353, a few minor issues, but managed to work through them.

Seems to be working OK, except for 1 minor annoyance.

Whenever I access the phone app I get a message saying 'This device is not supported and phone calls may not work correctly'

Calls do seem to be OK, if I bypass this message, as I have tried both incoming and outgoing calls.

Can someone please advise me how to stop this message appearing?

Thank you for a great ROM.

Doug
[Sony Xperia M4 Aqua] Gray47Maxx:
Okay, the deal isn't in your actions then - my phone was supported by Concept-ify, but after an usual reboot I've got the same error, and the only thing I did was making Half-Concept-ify - I've restored a stock ROM (smth caused my USB not to work anymore - perhaps, controller died), flashed all the patches and AFTER it I've flashed modified XZ UI. And I got the same experience)))

If you need it - feel free to ask me in Telegram (@Gray47Maxx) or in PM.
[Sony Xperia M4 Aqua] MrPilot:
hello!

I followed your first post and now I see I should've had flashed this "pack" BEFORE starting with step one:/ So can I still just flash in TWRP this AOSP? or do I need to start all over again?

You really need to put this post at the very top as a first step!! XZ UI? what is that? Is that needed? (I have UI crash upon starting)

Really update the OP and include all the necessary steps please!

EDIT: Is there is a full ROM with concept ify that's NOT mentioned so far with actual download links?
[Sony Xperia M4 Aqua] MrPilot:
I'm in the same situation as you. Have you tried re-locking your bootloader? Flashtool can re-lock using the same KEY that it stores for you. After relocking xperia companion app can then repair it? I'm 20% into the repair so far.

EDIT: Yep, phone is out of "Game Over Mode". :)

yay!
[Sony Xperia M4 Aqua] flaximuss:
Hey MrPilot,

Thanks for your reply. Actually before start play with my phone I did a full backup, so I'm pretty okay now.
[Sony Xperia M4 Aqua] Gray47Maxx:
It's an additional pack. Just install it after the main procedures and you're done!

No more. Just flash the patched SMK kernel (it has an UI fix) and it should work.

Concept-ify is only a pack of some necessary patches (like removing over 50+ pkgs) + an instruction for partition changing.

[Sony Xperia M4 Aqua] nzdge0:
Have been using this rom for the last couple of days, and while I liked it for the most part I have had to go back to the stock rom.

I had 3 issues with this rom.

1) Issue with the phone app as mentioned in post 83

2) Unit would not boot with the SIM card in, possibly related to point 1. Got around this by installing the SkyMelon 9 kernel, but would need to re-install on every reboot, otherwise unit would just sit on the bouncing ball screen forever.

3) Battery performance - this was the major killer for me.

On the stock rom I easily get over 48 hours average use of the device before needing to charge. On this rom, I was lucky if I got 16 hours of use.
[Sony Xperia M4 Aqua] Gray47Maxx:
This is not a bug, [QRCODE]this is a feature[/QRCODE]. Just tap anywhere else to fix it)))

Hm... Try to reinstall it... Or try to configure your phone before flashing the C-ify patches)))

This is... strange. Try to configure your kernel for a battery life (if it's SMK, then try to use ironactive + lock the kernel for min ~500 and max at ~1400)
[Sony Xperia M4 Aqua] nzdge0:
Had already installed the rom twice with the same results. Unit would sit at the first screen just waiting. If force closed it and removed the sim card, the device would boot, but as soon as I replaced the sim, it would reboot and then get stuck again.

The first time I ran into this I installed the busybox patch and it booted OK, so I thought it was sorted. but the next time I reboot the phone it got stuck again. this is when I installed the SMK kernel, and again, the device booted OK, the next reboot and the phone got stuck again.

Battery drain was noticed on both the kernel as supplied with the ROM and with the SMK kernel. I didn't do any tuning with them at that stage.

Will see how I'm placed to be able to do some testing later.

2303 gets stuck at the android animation logo and never boots. I first flashed a Baltic Generic ROM from Flashtool, flashed TWRP, then installed the REDUCE patch, backuped system and data, followed all the "parted" instructions and recovered system and data. I've tried it about 3 times now and it still refuses to work. Any idea what am I doing wrong?
[Sony Xperia M4 Aqua] nzdge0:
I had a simular problem whth my 2353 when I tried this rom. If I removed my SIM card the device would boot, but as soon as I replaced the SIM card the unit got stuck at the Android logo.

How I managed to get around it was to boot to recovery and then install the busybox patch from the OP this seemed to get it unstuck, until the next time I rebooted the phone. Everytime I reboot the phone I would need to reinstall the patch to get it to boot. Not sure what it did but it affected the system enough to get it through the boot sequence.

You have three options:

1. Reflash the ROM, config system before the patches, flash other zips

2. Try to install gapps pico, and then try to configure

Hey,

I have a problem with the step 6.

I'm on E2303 8GB. I started following the guide for 8GB users but sadly can't pass through step 6.

So I've put the 'parted' file in the root of SD Card. I installed the m4_reduce file.

Made backup, unmounted the system and data. (at least I think so, I just unticked the boxes)

So coming to step 6. I understand I need to turn off the phone, connect it to pc in fastboot and start ADB.

I'm typing the ' /external_sd/parted/dev/block/mmcblk0 ' command and ADB gives me this line:

'The system cannot find the path specified.'

NVRM managed to go past step 6, my bad !

Anyone has any ideas what I did wrong or what I should do to fix this?

Thanks in advance guys.

Also btw - After successful install of the ROM can I make the SDcard into internal storage or will it break something with this ROMs setup?

Cheers.
[Sony Xperia M4 Aqua] :
You didn't read it correctly,it should go /external_sd/parted /dev/block/mmcblk0,make sure there is a space between parted and /dev/block like written here and in the OP
[Sony Xperia M4 Aqua] Ephixi4:
Actually the problem was that I didn't write ' adb shell ' :P

But ye I did some googling and now know that spaces are also important.

Cheers!

[Sony Xperia M4 Aqua] thra1982:
The guide for the 2303 says:

-Restore backup

-Boot to system

-Reboot to TWRP

-Flash zip

So is the backup the e2303.zip file? And which zip has to be flashed after rebooting to TWRP?

Does the phone still has to be prepared according to the guide with partitioning?

Or is it ready to go if it's just for TWRP?

Thanks in advance. And keep up the good work ?
