(Avis aux intéressés, j'ai traduit mon message en français, et reparti une discussion sur Frandroid.)
Hello,
I managed to map the partitions on the Gio 5660M (Bell Canada, 2.3.4, MUGK3) in order to extract an ODIN flashable complete stock backup.
I have also made a stock, rooted ROM backup by working in a hex editor. Other tools that helped the mapping were Winmerge, to do file comparisons with an Euro 5660 ROM, and Notepad++ for string searches.
Those with a 5660M that are experiencing issues after flashing Euro 5660 ROMs that have been posted here now have the possibility of flashing back their original radio and kernel.
ROM development and deployment is going to be safer going forward.
I copied the blocks with the dd command as follows:
dd if=/dev/block/bml1 of=/sdcard/bml1 bs=4096
WARNING!!! DO NOT dd /dev/block/stl5 as there have been multiple reports of bricking following reading it. We already know that this block contains the EFS partition, including the SIM-lock code. You can however dd bml5 without issue from a "live" phone. If you absolutely want stl5, you may get it by using a rooted custom recovery.
From what I've gathered bml is essentially a lower level interface to the same blocks accessed by stl, but the results differ somewhat in resulting file size.
Here are the results:
Code:
/dev/block/bml1 MIBIB
/dev/block/bml2 QCSBL
/dev/block/bml3 OEMSBL
/dev/block/bml4 AMSS
/dev/block/bml6 Essentially empty, with a FSR_STL string at the beginning.
/dev/block/bml7 arm11boot
/dev/block/bml8 boot.img. My initial assumption was based on the .ops file supplied with the Euro ROM I've done my comparisons with. This has since been confirmed with actual flashing.
/dev/block/bml9 recovery.img for the same reasons as above.
/dev/block/bml10 Essentially empty. Mine has a BMC string at the beginning which matches the CSC code on this phone, followed by an ON and an OFF.
/dev/block/bml11 Empty. \xFF all around.
/dev/block/bml12 Seems to contain the same RFS data as stl12, but with an additional 8 megs of data/padding, not readable by MagicISO.
/dev/block/bml13 Like 12 above, but user data
/dev/block/bml14 As above, but the almost empty partition
/dev/block/stl1 cannot open for read
/dev/block/stl2 cannot open for read
/dev/block/stl3 cannot open for read
/dev/block/stl4 cannot open for read
/dev/block/stl6 Empty: contains only \xFF
/dev/block/stl7 cannot open for read
/dev/block/stl8 cannot open for read
/dev/block/stl9 cannot open for read
/dev/block/stl10 cannot open for read
/dev/block/stl11 cannot open for read
/dev/block/stl12 system.rfs - is flashable as-is once tarballed. Also contains the CSC files as we're taking this from a "live" installation, contrary to an OEM provided image. (My image is also rooted for the same reason.)
/dev/block/stl13 data.rfs - User data partition
/dev/block/stl14 cache.rfs - Odin hangs when I try to flash it. Use CWM and dd back into place from the SD card.
From what I see we can't repartition our phones like the GT-I9000 guys do, so there are no PIT files to worry about. Only the OPS files which ODIN uses. We're not able to flash with Heimdall in its current configuration as it requires a PIT file.
GT-S5660M_MUGKG3_stock_rooted_ROM_v2.7z (101.46 MB)
Un7-Zip, flash tarball with Odin using the "One Package" option. Tested working on my phone. I think it goes without saying that flashing this is at your own risk.
(PDA: S5660MUGKG3 PHONE: S5660MUGKG3 CSC: S5660MBMCKG3)
Tutorial on flashing with Odin, with link for the appropriate version for our phone.
I've released my custom 5660M ROM, ArpegGioMod.
Goodbye,

Wow,
Thank you very much. The screen brightness issues and problems connecting to the mobile 3G network were very troublesome.
I will be flashing this ROM back to my s5660m.
THANK YOU!
STATUS UPDATE:
I have successfully flashed the image to my phone, i had to rename factory.rfs to system.rfs in order for ODIN to flash successfully. Also, it may not be important but I noticed that your image is missing the csc.rfs file.
I copied it from another ROM but it still didn't take it.
Even with the CSC.RFS file missing, it SEEMS to work GREAT! No more screen issues or 3G problems so far, I will keep you updated!
Again, thank you for uploading this, Hopefully soon there will be a CM7 for the s5660m!
Cool! Please, pretty please let me know as soon as possible how it turns out. When do you plan on trying this? This afternoon or later tonight?
Depending on how much you feel at ease with experimenting, you might be able to make a modified OPS file and new tar archive to flash only AMSS and boot.img to your system. Boot in recovery to wipe cache and dalvik-cache, then reboot the phone in normal mode. *If* things go according to plan you'd be left with a custom ROM'ed and functional phone. Otherwise just flash the whole thing back to stock.
Good luck,
Darkshado

Great! You just made my day!
About the missing CSC file: CSC is an acronym for Carrier/Country Specific Code. The csc.rfs file is a partition image file that, as far as I can tell, is merged with the contents of the system.rfs partition. In our case, the CSC file would contain the APN settings, as well as the Bell proprietary apps like self-serve and remote PVR.
Instead, since I took the system partition from a live phone, the CSC content is already in the system.rfs partition. I think the idea behind this is that Samsung can release new CSC packages without having to update the whole firmware when "new" carriers add the phone to their lineup.
I'll see if I can edit the RFS partitions, (maybe by mounting them on the phone directly?) if so, I would be able to unroot, and make that separate CSC partition as well. That would make the backup completely stock, as if it came right from Samsung.
Another, simpler solution would be to modify the OPS file to skip the CSC partition.
One question: did you re-tar each file individually for ODIN to take them?
CM7 port: I'd love to have one on that phone as well, but I'm not in a position to tackle that project, yet. The good news is that since we now have a way to bring the phone back to stock, we can experiment safely.

No, I use linux so it was an easy process of copying the factory.rfs to my HDD, renaming it to system.rfs, deleting factory.rfs from TAR, and then adding system.rfs to the TAR file.
Let me know if you want me to try anything else, as I have access to linux and am pretty knowledgeable when it comes to things of that nature.
I can confirm that replacing amss and boot.img for 5660m from custom firmware meant for the 5660 works perfectly. I am using this tar: GioPro-1_2-LITE-by_ZimniY-S5660XXKQ6_S5660XXKQ5_S5660SEBKQ1.tar AND the GioPro 1.3 update zip. No screen issues or 3G problems. If you like I can upload the edited ROM for ODIN.

Why is your phone stuck in an infinite loop? What did you do to cause this?
did you somehow overwrote stl5(the efs partition afaik) while trying to unlock your phone?

Hello Coolty,
Yes, that's exactly what happened. I tried to unlock it using Andorid Terminal Emulator, and although it gave me the unlock code, it fell into infinite loop upon restart.
Will your uploaded file fix this problem?
What would possibly provide a detailed guide on how to use the file?

Hi,
I'm not one for explaining things in great detail, but the basic breakdown of the things you need (google is your friend) are:
1) Odin_Multi_Downloader_v4.42
2) The USB drivers for your phone (Hint: Samsung Kies)
3) OPS File (for this phone, I recommend GIO_v1.0.OPS)
4) Either a single TAR file or multiple files (eg, appboot, PDA, etc) For the file I am uploading it will be a single TAR file which is a package that includes all the things needed.
Then, you just remove the battery in your phone, unplug it from USB or wall charger, put battery back in, hold vol down + HOME + power until you see a screen (you may have to press a vol key after that, read the screen to see if you need to) Your screen on the phone should say DOWNLOADING... This is when you:
1) connect phone to computer via USB after installing drivers (kies, usb driver)
2) make sure kies is closed
3) run ODIN
4) choose the proper OPS file
5) click single package
6) choose the TAR file you want to flash to your phone
That's it!
EDIT:
I am providing some forum links that may better explain how to do what you need done:

Will this help at at all with a blank IMEI? I assume this would only help for people flashing back to stock firmware or recovering from a non-bootable or reboot loop phone?

Thats why i recommend you guys always do a factory reset before and after flashing , these glitches , like gps issue , wifi , stuck on boot logo , won't happen if you properly fectory reset before and after flashing....
Waqasshazad: Maybe wiping the caches will help, but the issues might be due to running a 5660 on a 5660M as well. We know the kernels and modems aren't compatible, it may go a bit further. By the way, it's spelled factory.
MacrossFX: I've seen mentions of people dd'ing their stl5 partition into a file and then back on the phone, but I'm unsure this worked in the end. I'm afraid your only solution might involve a shipment to the service center...

I followed your instructional video and did do a factory reset before and after. Maybe i'll try reflashing it again tonight and see what happens.
Not sure if general is the place for this but I'd like to start a "formal" discussion of the KDZ files and what they precisely contain.
full disclosure: I'm not a pro with all this stuff, I'm primarily just curious, and know my way around well enough I can do some basic investigating
Here's what I've looked at so far, and what I'd like to do:
So far:
The Telus E973 KDZ file retrieved from LG's servers contains a cab file, which was initially extracted using LGExtract (http://forum.xda-developers.com/showthread.php?t=1566532)
Inside the CAB is a .dz file and a .dll (G_TDR_0141.dll)
The .dz file does not contain any headers for existing "known" .dz file formats. (For example: http://www.frenchcoder.com/dzextract-lg-dz-file-format-and-extract-tool-lg-ks20/)
It would seem that flashing the kdz using the method outlined in potatohead's thread does not 100% recover from a brick, but seems to depend on what the actual problem with the phone is.
What I'd like to determine:
What exactly is in the KDZ? Does it contain all stock partitions for the phone or only selective partitions. (such as /system)
Out of pure curiosity, when I have time, I'd like to compare the hex of the .dz file, to see if it contains any of the known stock partitions such as the aboot, boot, or recovery. I have this sinking feeling that it doesn't include the recovery based on chadouming's experiences with it. to see if the .dz file is compressed in some proprietary fashion, or if it's a simple arrangement of the stock partitions with some standardized headers.
Please feel free to contribute, or criticize me, I'd just like to fuel some interest and discussion.

Good to know. I think the one case we've had so far where this didn't work had some "advanced" issues, possibly involving partition table being messed up, which I have a feeling the KDZ flash wouldn't touch.
SmartFlash will be nice to have it completely restore everything to factory default and it is easy to use.
But for SmartFlash we need to convert the KDZ files in to BIN and FLS.
There is a tool for that but works only for P990/P970/P920 firmware's.
http://forum.xda-developers.com/showthread.php?t=1692191
Unfortunately the Rom converter does not work with the firmware's from new phones like Optimus G / Optimus 4x.

I think this is due to the fact that they've made changes in the actual .dz format as any existing tool I've tried cannot find any known headers in the file. When I have some time I'm going to see if I can narrow down any patterns/headers.

I don't know about DZ files, but the wdb format that my P970 uses can be made into a AP bin file that is essentially all the partitions of the phone and all the partitions with size (size on the file, not size of partition on device) 0 is skipped over.
I say split up into partitions but it's actually data blocks and can cross over partitions since it uses raw write to device and it looks like a convenience that it's set up that way.
Check out this thread.
It's a tool for extracting kdz and wdb files (dz planned).

There is a modem for the optimus G here:
http://downloads.codefi.re/houstonn/lgog/modem/E975_E977_E976
but it is from firmware 10b. You may want to try if it works better than your firmware. In this case, it is better if you make a backup of your current modem firmware, so you can go back to your version. Here I will write instructions to backup your modem, so you can restore it if you need.
Probably some of you know this already and feel like these are old news, but maybe we can build a modem firmware library.
You need root and a way to make an adb connection to your phone. If you cannot use adb, you can always use a terminal emulator on your phone, but this makes it a bit harder to type the commands. Also, this is for people who understand what they are doing. If after reading the tutorial you don't understand what the commands do, please don't try it. Or at least don't make me responsible if your phone bricks. Here we go.
NON NEEDED STEPS: This steps are here to show why this works.
1-Connect to your phone by adb.
2- On the terminal type :
Code:
mount
You'll see the following (amongst other things):
Code:
/dev/block/platform/msm_sdcc.1/by-name/modem /firmware vfat ro,context=u:object_r:radio_efs_file:s0,relatime,uid=1000,gid=1000,fmask=0337,dmask=0227,codepage=cp437,iocharset=iso8859-1,shortname=mixed,errors=remount-ro 0 0
This means that the partition containing the firmware is /dev/block/platform/msm_sdcc.1/by-name/modem and it is mounted at /firmware.
NEEDED STEPS
1- Connect by adb
2- On the terminal type
Code:
su
Check if confirmation is needed on the phone screen. If needed, accept.
3-
On the terminal type:
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/modem.img
4-You will receive the following after some seconds:
Code:
131072+0 records in
131072+0 records out
67108864 bytes transferred in 29.959 secs (2240023 bytes/sec)
5-Type
Code:
exit
exit
adb pull /sdcard/modem.img
6-Now you have your backup.
HOW TO PACK THIS BACKUP FOR FLASH:
1-Download the file: cwm-lgog_e975-europe-10b_modem.zip from http://downloads.codefi.re/houstonn/lgog/modem/E975_E977_E976
2-Open the zip file and replace the existing modem.img with your file
3-Rename the file to something meaningful, like cwm-lgog_e975-europe-10f_modem.zip
After these steps, you should be able to flash any modem, knowing that you can go back to your old version.
You can upload the packed files here, so we can have a library. I will upload the modem from european 10f version here. I tested it and it works correctly, but I won't take any responsibility for what you do with this file.
Good luck.
All this info is obtained from examining the houstonn LGOG modem flasher from team codefire, so all thanks go to them. Thanks.

could you please do the same thing for the misc partition and upload it somewhere?
I saw that freegee is touching this one so please mention if your phone was opened with freegee.

I am sorry, I am not going to upload my misc partition, as this partition contains my IMEI.
I can, however, tell you how to backup it:
Code:
dd if=/dev/block/platform/msm_sdcc.1/by-name/misc of=/sdcard/misc.img
Can I ask why you need that?

I had no idea the IMEI is also there. I asked for it because the baseband version is also stored there and it's kind of odd to know I'm flashing the modem from EU-10f and the displayed version is TW-10a. I'm still hoping to solve that issue.
Ah, OK. Tomorrow I'll check if the misc partition can be mounted, this would make editing it much easier.

I think it is not possible to mount the misc partition.
“In any case, the misc partition isn't a "filesystem" partition as you are familiar with. It is actually just a simple data structure. In fact, only the system, cache, and userdata partitions are actually filesystem partitions, and the cache partition is only a filesystem partition part of the time -- during radio and spl updates, it also is used as a simple data structure with a header field and a payload field...”
http://forum.xda-developers.com/showpost.php?p=7254425&postcount=3
I was trying to find some additional info about this structure but without success so far.
On may F180K the misc partition has 16 777 216 Bytes. Some interesting offset:
0x8000 – 0x800E IMEI (15Bytes)
0x8800 – 0x8824 Baseband version (37Bytes)
0x9000 – 0x9024 Baseband version (37Bytes)
CyanogenMod display the last one data on the Settings->About phone->Baseband version

Thanks.
You are totally right, this partition is not a filesystem. And it is mostly empty, it's all zeros except for some bytes. Most of it are text strings, but there are some small binary parts.
I think the 0x8800 - 0x8824 part is the original firmware version.
I wouldn't touch that partition, seems too dangerous .

freegee touches it. I see it made a backup and the difference is that it changed some bytes to 0 (offsets 0x40-0x52), then wrote ANDROID-BOOT at offset 0x4000. the rest is the same. it seems there's nothing like a crc so basically I could write whatever I want in that version field. the bad part is that as an user you'll never know what modem version you have since its version is not stored on the modem partition. I wonder who came up with this system and what was he thinking.
thanks for the clarification. offtopic over .

Some time ago I had the same issue. I solved it by modifying binary data on the misc partition. I was done this only on CM10.1 (F180K). I don’t know if it will work on other custom rom especially stock one.
Today I’ve done this one more time for preparation the following procedure. Maybe some one will use it on the future.
STEPS:
0. Backup the misc partition with your recovery. I was used CWM Advance Edition PhilZ Touch 5:
Backup and Restore-> Custom Backup and Restore->Custom Backup Job->Backup misc (*)
I’m not sure if all CWMs version support misc partition backup. TWRP not support it right now.
1. Dump the misc partition to /sdcard.
Code:
adb wait-for-device
adb root
adb shell "dd if=/dev/block/platform/msm_sdcc.1/by-name/misc of=/sdcard/misc_orig.img"
OUTPUT:
32768+0 records in
32768+0 records out
16777216 bytes transferred in 6.539 secs (2565715 bytes/sec)
2. Pull the image to your PC
Code:
adb pull /sdcard/misc_orig.img misc_orig.img
3. Edit downloaded image file by your favorite hex editor (e.g. Notepad++ with Hex-Editor plugin)
Find both baseband name strings (mine were on offset 0x8800 and 0x9000) and change them (CM10.1 use the last one to set gsm.version.baseband in file /system/bin/fetch-swv).
REMEMBER:
- Do not use regular text editor (like Notepad or vi) – they can add some extra characters to the file.
- If possible try to modify only bytes responsible for original baseband name. If the new name is shorter, simply put spaces char (0x20) to clear unwanted chars. If you need to put the longer name, be careful. I don’t know the max size for this string. There are dozens of zeros behind the baseband name on my image file. So, for testing I added extra 20 Bytes text. The new baseband name was shown without problem.
4. Push the modified image file to your phone
Code:
adb push misc_orig.img /sdcard/misc_mod.img
Check if size of the original and modified files are equal.
5. Write the modified image to the misc partition
Code:
adb shell "dd if=/sdcard/misc_mod.img of=/dev/block/platform/msm_sdcc.1/by-name/misc "
OUTPUT:
32768+0 records in
32768+0 records out
16777216 bytes transferred in 4.183 secs (4010809 bytes/sec)
6. Reboot your phone
DONE.
Hi all,
I just create a .zip to backup your modem / baseband / radio with your recovery (CWM / TWRP...)
ok as a newbie i cant figure out how to back up modem using adb... but after reading stuff what i did :
downloaded "Android Terminal Emulator" from playstore
open emulator in phone wrote as u mentioned :
su
dd if=/dev/block/platform/msm_sdcc.1/by-name/modem of=/sdcard/modem.img
after some seconds this came out :
131072+0 records in
131072+0 records out
67108864 bytes transferred in 15.229 secs
then :
exit
exit
after that i checked sdcard but there was no img file...
then i open file manager from the phone and there it was my precious :laugh:
size = 64mb... is it normal?
anyway .. made a new folder "modem" copied the img file into modem folder (using file manger) again connected the phone to pc copied the modem folder on my desktop...
hope it will help new guys here like me :good:

Get back to JB and wait for your midel update
Back to JB I recovered the IMEI, but I have no carrier signal.
So do the root with towelroot, unlock custom recovery with FreeGee, do I back up EFS, and when I restart the machine it loses the IMEI.
So I install the modem and E97710b.kdz for E97710b model recover EFS and nothing happens, still no sign of the operator ...

Hey Guys,
I did a stupid, and yes, I should know better, but I did not take a backup of my build.prop of my freshly rooted d852 when I edited it in Root Browser. It truncated, and lost the bottom part of the file before I noticed, and long story short, I'm missing some system sounds, and would like to know if anyone has a working d852 build.prop for a Rogers G3 Stock 4.4.2.
I downloaded the TOT file from a link in the help FAQ, and tried flashing using LG Flash tool, but it would get to a certain point, and Fail, not being able to switch to download mode, so I was not able to reflash to complete stock for whatever reason.
I'm now toying around with LG TOT Extractor, seeing if I can extract the ext4 FS files, and get a build.prop from there,
Any pointers?
Thanks
Everett
Did you try flash tool on windows 8? I Had a issue on windows 8 wich gave me the same error.
Download KDZ (http://lg-firmware-rom.com/)
Extract KDZ using this tool (http://forum.xda-developers.com/showthread.php?t=2600575)
Merge system.bin using the same tool
Extract build.prop by opening system.img using Diskinternals Linux Reader
And next time use this app instead of the stupid stock lg flash tool that requires tot files

Hey guys,
It seems more and more people are receiving the new version of the P8000:
- Stock Android 6
- New fingerprint scanner that is moved slightly higher and is able to unlock phone from screen-off (I confirm this is working)
- Sim 2 is combined with the micro-sd (I haven't tried whether you can have them both in at the same time)
- Somethings new about the display, since people are reporting errors with it after flashing older roms.
Warning: do NOT flash other roms. We have no way to unbrick the soft bricks yet!

For development:
- The phone does not come pre-rooted. We have no way to flash custom recovery yet. Any tips for getting root? I've tried such tools as Kingo and vRoot, they don't work.
- We need the blocks file (scatter file) for SP Flash Tools. MTKDroidTools reports "unknown rom structure". Any help? Would love to start working on this.
Looking forward to hearing from others who have this version/who can help me with these questions.
Thanks!

Nice! Can you provide a dump from /system and /boot maybe?

Sure thing. On a rooted device, go into adb shell.
Then use "mount" command to check which partitions are mounted. One should be "/dev/block/platform/mtk-msdc.0/by-name/system" or similar. Use "dd if=/dev/block/platform/mtk-msdc.0/by-name/system of=/storage/emulated/0/system.img bs=1M" to dump the system to the internal sdcard to the file "system.img". If adb complains that bs=1M is an invalid option, try again without that one. A system dump can take some time where you will not get any feedback, so be patient there
Do the same for boot. So "/dev/block/platform/mtk-msdc.0/by-name/boot" should be the way to go for the path. I cannot tell the definite pathes on Android 6.0 but I am rather sure they are more or less like this.
If you run into troubles, just ask

Thank you for your great instructions! The problem is that we've yet to achieve root on this device. We don't have a custom recovery for this version of the P8000 yet and other 'standard' methods of rooting don't work for me.
(I'm pretty solid in shell, so I'll do this afterwards, but I guess root is actually the first step).
// Edit to say: it does not come pre-rooted
Since the elephone support on facebook didn't realize there are two different versions of the P8000 available, I still need a ROM to unbrick my phone.

Ok, we know that, but doesn't really help us
Can you write them an e-mail?
I will do
Edit: OK, see if there will be an answer.
Thank you flo1k!
I have e-mailed as well, and would like to post on the Elephone forum, but don't seem to have access (because of minimum post count, I guess)
Anyone willing to ask for a ROM for the new P8000 on the forum there?
ROM Dump
@BlueFlame4
I can provide ROM dump in two versions:
1) a dump from adress 0000 0000 to 9d80 0000 (apr. 2.5 GB in one file)
2) a readback generated with the scatter.txt of the 'old' 5.1 stock ROM (apr. 2.8 GB seperated in 23 files)

The second choice looks promising
Maybe a stupid question
where shall I upload the files - any preferred webspace?
I'm uploading the files - because they contain my NVRAM I send the link as PM as soon as the upload is finished

Are you sure we're talking about the same version of the P8000? Cause as far as I know there isn't 5.1 available for this version... Right?
Just checking thank you for your help in any case!! Really looking forward to it.
// edit: ah, you just used the old scatter file. But does that one work for this version?

No, there is only one Firmware available - the mysterious P8000_6.0_20160516.
Btw, this Phone contains a new mainboard model "K06TS-L-V2.0.3" - the 'old' mainboard is moder "K05T...."

No, it doesn't work resp. the phone boots with this firmware, but the LCD-driver is the wrong one - the display only shows coloured lines and blurry spots. And there are probabely some more bugs ....

But if the phone boots with the firmware, doesnt that mean that the scatter file of the regular P8000 works? Since it flashes the firmware correctly.
The problem is that I was not able to flash the 'readback files' to the faulty phone.
When selecting 'Only Download' at SP-Flashtool I got the error "PMT... must be download"
When selecting 'Firmware Upgrade" I got some BROM error code
In both cases I used the same scatter,txt which I used to 'readback' the firmware from the working phone
Actually I have to correct my statement in post #15:
I flashed the faulty phone with the last 5.1 stock ROM (160711) - with this stock ROM the phone boots up but LCD (and probably more things) is not working.
I have actually gotten alot further
You have the use the scatter.txt from Android 6.0, which works perfectly fine. I have been able to extract boot.img, system.img and recovery.img that way (using Readback in SP Flash Tools)
Which ones do you need?
They probably flash fine (only thing I've flashed so far are custom recoveries, and although my ported PhilZ starts, I havent gotten it to mount anything.)
A little warning: don't use anything that has anything to do with Android 5.1. Those scatter files don't work
These are great news!
"Which ones do you need?"
Probably all of them
Ok this contains the scatter file, preloader, system.img, boot.img and stock recovery.img
https://ehaffmans.stackstorage.com/index.php/s/uKGKCir0BociydU
You need SP Flash Tools v5, select the scatter file first, then deselect everything, and only select these 4 and manually select the correct files.
Btw, the name of the preloader file is wrong, don't worry. It came from this phone
I am of course not responsible for anything!
Can you guys please confirm this doesn't contain anything personal? Like personal files or IMEI or something. Thanks!
