[Q] having trouble flashing rom into samsung captivate I897

[Val D.]

To restore your GB backup you need to go back to GB first. Same thing with JB backup, you need to install JB first. Partitions are different, CWM Backup/Restore won't repartition your phone. Similar thing with flashing ROMs - from GB you can flash back and forth different GB based ROMs, but once you flash JB it will repartition your memory and going back to GB is possible only with Odin. Once you have JB 4.2.2 running you can flash any other 4.1.x - 4.2.x (same partitions), but if you try JB 4.3 (CM10.2) it will again repartition your memory and going back to 4.1.x - 4.2.x is a little longer process (back to stock -> flash corn kernel -> flash JB once to repartition -> flash JB second time to install ROM).

Flashing kernels - make sure you are looking at the right kernel for your Android version, download *.zip file, flash in Recovery, reboot. In my experience Devil 4.2 and Semaphore 3.0.0 work best for JB 4.2.2 based ROMs. Gear/CyanCore are modified Semaphore. I don't like too much tweaking though. You can't make Captivate run like S4, playing with kernel settings usually brings nothing more but stability issues.

Just don't kill your phone with too much flashing excitement, read carefully installation instructions for every ROM you want to try.

Here is a Dropbox link to one of the latest Devil kernels for 4.2.2 ROMs - Devil4.2_i897_20130704

Ok and how to back up apps installed?? as it is a long way to download and install from Google play after flashing new ROM

I'm using Titanium Backup. It backups apps + data + system data you want (accounts, call logs, sms messages, wifi settings, etc.). Just backup everything before you flash a new ROM and you will be able to restore 90% of your system in minutes. You need to go through system settings manually though, every ROM has different settings. Full version of Titanium Backup is a paid app, but you may find here and there full version apk, use Google. I never restore the phone via Google Play, it's too slow.

After trying almost all available custom ROMs for Captivate I came to a simple conclusion - light AOSP ROMs work best on a single core CPU and limited RAM phone like Captivate. Full featured and themed ROMs with endless options are good to see, but not very good for every day use. Our phones are not capable to handle well all new custom ROM additions like halo, ribbons, side bars, pop-up notifications, etc. and offer smooth user interface in the same time. Remember, you have only about 150MB available RAM to run all your apps.

sorry for disturbing you once again the problem is my phone eats battery too soon. it was not an issue with stock GB ROM. i didn't flash devil kernel, my kernal is unofficial semar phone and it came with that xperia Rom, from 9:30 Pm to 7:00 AM battery went from 76 to 42 percent while the phone was totally Idle( not opened lock, no screen awakes). what could be wrong?? :crying:

Check battery stats first and see what is consuming the battery.

It is driving me nuts, how can battery drop down upto 40% in a night(8 hours) while the screen is not turned on even once :crying:
gonna flash Devil kernel now, i heard it makes battery life stable, will tell you the outcome. Battery life was ok before flashing xperia ultimate ROM.

 

[Mr Ashar Majeed]

Yes that ROM is fine. Make sure you understand and follow the FULL instructions in the ROM's OP.

Hey sir do you have any idea what might be the reason of battery dying soon and what could be the remedy ?

 

[BWolf56]

It can be a LOT of things. Did you try using better battery stats? With it's log i could tell you what's draining your battery (if you don't understand it).

I have a 2-3% chance to find it by taking guesses.. Which is not very realistic.

That is a paid app. I don't wanna spend on that app. from setting > battery, android OS is always above 40% . Flashed Devil kernel today but this didn't cure my battery problem as i hoped it'd It took some RAM away though, with semaphore i had 409 MB but devil gives me a maximum of 391MB . considering to reflash semaphore

 

[BWolf56]

We don't tend to suggest paid app. BBS cam be found here for free (in the app section). That being said, it's well worth it's cost.

Android system being high can mean a few things. Do you have GPS, bluetooth, wifi always on?

Do you have bad signal?

I could keep going for a while with my questions but BBS will straight up give us the answer to your problem.

what do you mean by APP SECTION? can't seem to find it :laugh: opppshh
GPS/BLUETOOTH never... WIFI often but i turn that off when i'm not using it. I installed a CPU tuner and i set power max to 1.2 GHZ (from obviously 1.00GHZ) but when i started having battery issue i put it back to 1 Gig just in case it was the culprit but it wasn't i reckon
hey hey just noticed My SCREEN is 47% (setting > battery). This evening i noticed screen at above 30%. I don't use high brightness, just put my phone on full dim while at home and a little above from dim when i'm outside. ANDROID OS is currently at 8%

Screen being top is basically what you want. On normal use, what drains the most the battery of a android phone is the display.

So if you have screen at 47% and android at 8%, that sounds quite normal to me.

Also, OC will drain your battery faster. You can help it with UV but I wouldn't suggest it on the cappy. Also, using more battery friendly scheduler and governor (in your kernel settings) will help.

As for BBS, have you tried a search? It's probably one of the most searched thing on the forum.

2 things:
- Captivating ROM never got official stable release. Some users report earlier versions run better.
- 409MB RAM means broken video playback + no 720p camera recording, test ans see for yourself.

Hi Hey Hello hope you're good I'm busy preparing for my final Exams so couldn't talk. My battery problem is solved automatically, IDK how but it is not an issue now although i still feel battery dies bit quicker than it used to be (when phone didn't have that quick battery drain issue). I never had good download speed while using Captivate but now things have worsen for me as download take ages.. Literally Ages "Sigh" . it downloads 30kps and rests a few seconds then it again dowloads 30 50 kp and then rests asd so on... please help what could be wrong now? my intternet/router is ok as my lapi downloads at 200 -270 kbps average.

 

[Mr Ashar Majeed]

cyanogenMod version 10.1 RC2
Devil kernel 3.0.85
Rom is xperia ultimate

I can't suggest a modem cause they have different results depending on your area and phone. you will have to test them: http://forum.xda-developers.com/showthread.php?t=1227717

You can flash any ROM that is 4.1 and up following their FULL instructions. A ROM being based on CM doesn't have any affect on whether you can flash it over your current or not. They get fully wiped when you wipe system.
