hey guys, i have tested many recoverys (even from htc one sv) and nothing works so there is no workaround for this, i will have to set up ubuntu and build CWM or TWRP from source.

i attached the stock recovery for i8730 in case u test other recoveryes, now you can revert to stock easy without having to flash the whole stock firmware.

extract the zip file, and flash this with odin

Anyone can help me on how to open up the recovery.img file to see the contents further inside? Cos I wanna try mixing some display related files frm the serranoltexx CWM 6.0.3.5 with the ones frm stock recovery hope it work. I dumped the stock recovery out via an app called Flashify btw... I done plenty of search on the web n I can't get a tool frm Windows platform. I done some search on XDA too but the process is complicated with some linux commands but required a Linux OS. Thanks! :o

Hey guys, if u wanna flash back to stock recovery while work by petratu is in progress this is an alternate method to do it without using Odin... But then, you must make sure your device is able to be powered-up nicely... It's a great tweak I feel myself...

1. Download Flashify from Play Store or from here: http://dl.papktop.com/2013/07/Flashify_for_root_users_1_0_5_1.apk and install APK on device.

2. Download the stock recovery for i8730 from here to device at Sdcard0/flashify-backup/recovery folder:

Stock Recovery for i8730 (6.9 MB)

https://mega.co.nz/#!CQgG3KgK!eW6wIxtfWLyOfBa00Ns1QRgVmx8lHmzm6JlQDucfRTA

3. [Root is definitely required] Run the app Flashify and go to the Backup/Restore. There will list out your current kernel n recovery type. Go to Restore Recovery and select the downloaded one.

4. Press 'Yup!' and the flash is done perfectly! Stock recovery is back now too! You can now press Vol Up + Power button to enter back stock recovery. Enjoy! Cheers! ;)

You have a stock recovery in post #5.

Just in case I link my own stock recovery and ROM:

- i8730 stock recovery

- i8730 stock ROM

Best.

I want to try a new build using the stock zImage (kernel). Can anyone tell me where can I put the stock zImage so that the CM build process will take this instead of building its own kernel? [MENTION=5093942]KINGbabasula[/MENTION]?

Thanks.
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] jjchico:
I think I found myself about building with a custom stock kernel in the CM wiki. I am trying a new build right now.

I have set up some Github repos (forked from [MENTION=5093942]KINGbabasula[/MENTION]'s and others) in case you want to follow my changes.

* android_device_samsung_expresslte - originally from KINGbabasula.

* android_system_core - mkbootimg updates

* proprietary_vendor_samsung - expresslte blobs

Can someone express user do me a favour??

So heres the story. My express is rooted, and decided to delete some samsung and google preinstalled apps with titanium backup. Then I when im on uninstall tab in titanium backup, I accidentally clicked the tick button while all my apps (user/system apps) were all ticked.

Then I immediately rushed power off my device using the power button. The last thing I saw before my phone shuts off is Youtube was in the process of being uninstalled. Then my shuts off. I panicked. I thought "oh no, now my phone is ****ed, maybe titanium backup also delete my other important system apps by accident too".

I reboot my device. And checked, yes YouTube was gone. I thought my youtube app was the only one gone, but XDA app was gone too. So I thought to myself maybe it did deleted my other app without my caution too but I just didnt know which one it deleted.

Idk why the uninstallation process starts at Y first which is Youtube. Maybe it did uninstall my system apps that starts after their first letter was Z and number-A.

I know this maybe is not a big deal for u guys. But im a super duper neat freak person. 1 system apps uninstalled or any other user apps uninstalled without my notice or caution or without me knowing what the app is im gonna go crazy!!! So pls, do me a favor here

So can you guys express user please post a screenshot of all your app using titanium backup. From the top, and the bottom. Stock rom preferred. Heres some example.

Wished I can thank you 1000x but I cant. Even though strangely enough right now I cant find the thanks button. Will thank you later.

Good news is the only thing I found missing are Yahoo! Finance and Yahoo! News.

Im not sure if I have those two apps before. But oh well. Even if I have those two apps, and titanium backup did deleted it. I dont mind. Seems like a crap app anyway :D

Thanks again. Much appreciated.

Guys, some tips, edit them in build.prop

for a smoother scrolling, disable scrolling cache

persist.sys.scrollingcache=4

disable logcat, it will provide a small performance boost, dont disable this if you need logcat

logcat.live=disable
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] aureljared:
I think you have to manually replace the zImage after building or use the Samsung 3.4.0 codebase instead (from opensource.samsung.com)

Good luck with that.

Hi mate, excuse my ignorance, i gather this is a cwm update, i think, if so should we do the same do it with Odin, or is there a way to zip it and flash it from recovery, I've only been able to do that a couple of times, every other times it didn't work, thanks?
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] aureljared:
You can't flash a recovery within a recovery, I think.

I completed a build from [MENTION=5093942]KINGbabasula[/MENTION] a couple of days ago. Was my first build so could be I am doing something wrong.

Had the same hang at the logo and couple of buzzes as before so was looking at trying a different kernel, maybe from the s4 mini as the hardware is similar. Is that too risky? Do not really know what I am doing.

Hi, there's no need to uproot your phone, just connect it to your pc.

Not really an advance but I got:

- Built recovery image works provided stock kernel is used. CWM 6.0.4... I can upload the recovery image if you are interested.

Currently building with samsungs' provided open source kernel.

See my setup from the local_manifest.xml in the repo below.

[Samsung Galaxy Express GT-I8730 Guides, News, & Di] aureljared:
Please upload your 6.0.4 CWM so that we may be able to flash future 4.4+ builds.

What toolchain are you using for the kernel?
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] aureljared:
[MENTION=2562109]jt1134[/MENTION] suggests that we use d2-common's kernel source.

Also, he says that we have to port drivers from the Samsung OSRC kernel source into the msm8930-common tree before building with the serranoltexx template if we're playing with CM 10.1+.

I tried just now to make the backup having new recovery (not the restoring).

And found that the first option "backup" is placing the files on internal sdcard. It was the wrong way :)

So, I cleaned the memory and choosed second time the option "backup to external sdcard" to make the correct backup.

Before this I made a backup with recovery 6.0.3.5. The total size of the backup was 4.82 GB and it took to be made aproximate 12 minutes.

For the new 6.0.3.7 recovery the total size of the backup is only 2,41 GB and was made much faster - in aproximate 6 min.

I didnt changed some applications/data in the smartphone. (2 screenshots are attached).

aureljared, can you please let me know why apprears this difference in the backups sizes and their time to be made.

Did you added some compression?

Thank in advance!

PS

Do you think that for the next recovery will be possible to correct the date and to add the usb mounting in Windows?

PS2

It can be useful for others to add few words to your original post about the "backup to external sdcard" to avoid some mistakes :)
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] aureljared:
[MENTION=5093942]KINGbabasula[/MENTION] Yes I do. Find me by my name (Aurel Jared Dantis) or email (jareddantis@gmail.com)

[MENTION=4398436]Garmus[/MENTION] That difference in size may be caused by the amount of free space you have. Does CWM spit out any messages while backing up?

I did not modify the recovery in any way aside from the kernel.

PS: The recovery partition doesn't talk to the rest of the phone except when backing up/restoring/installing zips etc. Therefore the date will be perpetually 1/1/1980.

PS2: I think they'll figure it out on their own. But I'll update the post later anyway.

But I didnt make any changes in the phone. Same microsd card, same smartphone, same data and the ohers same...

Just reflashed the both recoveries and checked for each the sizes and time for backups. In fact, I like more the last recovery because the backup take less space and is faster...

I hope to have time to try this weekend how is work the restoring from backup... may be for the both backups.

Hey guys, sorry for my low activity, but i really can't find time to build anything... i can only post some tips and tricks,

so, for better scroll and performance install setcpu and set min cpu freq to 648, in my oppinion is the best freq for good scrolling performance/battery friendly, higher low freq is set, less time for cpu to scale. You can see cpu freq with cpu-z

And you can set governor settings to this

up threshold 70

down differential 15

i left sampling rate 50000

in general, low up-thresholds and lower sampling-rate means performance. This way, governor polls more often and scales up quite often.

For battery saver is the oposite, set high up-thresholds and higher sampling-rate. This way, governor polls less often and scales up less often.

Recovery built from sources

Hi!

I booted a recovery built from serrranoltexx cm-11.0 sources but I get the wrong display size/color as happened with the initial [MENTION=5246389]aureljared[/MENTION] recovery. Could you give me some clue about:

1. Change recovery display size/resolution in cm-11.0

2. Make the change after compiling (if possible) to avoid a whole build.

3. Build instructions to just build a recovery and not the full ROM

2. Not possible

3. make recoveryimage is the command to build only recovery after lunch
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] jjchico:
1. I had graphics.c already deleted since started over from the serranoltexx source. I have copied it back from your source to try.

2. :(

3. I did after "breakfast expresslte" but did not get a "recovery.img". I am trying back after "luch cm_expresslte-eng".

UPDATE: Same result using dedicated graphics.c. You can get the recovery.img from:

Yesterday I could see a full CM compiled CWM running behind a foggy blue screen. I was able to install CM from it and I could boot CM (with the foggy blue screen). The booting stayed at the CM start animation. I think this is a step forward considering I have not included any specific kernel drivers or binary blobs yet.

You have everything in my github repo (jjchico). Look for expresslte device folder, cm-11.0 branch and adapt the local manifest.

Now one question: I am currently basing on serrano-common. Is expresslte close enough to derive from serrano-common or should it get its own common tree. In particular, there are some proprietary blobs in serrano-common that are missing in expresslte.
[Samsung Galaxy Express GT-I8730 Guides, News, & Di] szezso:
Sorry for being quiet guys. I have the phone now, but I'm testing it with the stock ROM, yet. :) If it has a problem, then I can go back to the store with it.

I'm in Belgium at the moment on holiday, I'll go back to home at the 5th of January, and if it still doesn't have any problems, I'll try my build out. :) I really hope (and I know) that we'll have a booting CM ROM in January! ;)
