Lava iris 501 friends, here's a link to rom I am using for a month now.
you may need to hunt for a 4.2 based kernel as on few devices this may give crashes to messaging and few other apps.
there are many compatible kernel on XDA already, search a bit, as posting kernel link is banned on xda with source.
Finally after trying many 4.2.2 ROM's I've managed to RUN 4.2.2 on Lava Iris 501, pure 4.2.2 experience,
its used as daily phone for last 10+ days and I am pretty happy about it. Solved almost all Issues I came across and no crashes are experienced.
I am using kernel 3.4.0 with it and its pretty stable, works good whole day with 90% WI-FI + 10% 3G.
ROM is stable and running smoothly and doesn't crashes even in 2-3 days of continuous run, however I am not able to try beyond that as customization or modding stuff makes me reboot the device usually every other day if not daily.
I would be happy to share it here and on XDA once I get permission from Porter who originally ported the ROM for some other device.
Will keep you guys posted and would share a link in coming weeks.
This is a un-confirmed bug, best option to overcome this is to Remove your Google Account and re-add it manually.
If you are restoring backup using any app. like titanium or others, First Add your Google account to phone manually, then restore everything except "accounts"
this should certainly solve your issues.
If your playstore still shows Old version, keeping data or WI-FI ON, Exit playstore, and re-open it in a few minutes, it would get upgraded to latest.
The ROM provided by Lava Is a Jelly Bean version 4.1.1, which is certainly better than ICS, but it misses a hell lot of features
this seems to be a stripped down version of JB release, and many functions have been removed to make it run on 512MB RAM.
Bugs and missing features:- Earlier the phone used to vibrate when a outgoing call was picked by called person, this feature is missing. Dialing only a few digits used to very intelligently detect the matching phone numbers, this feature is missing. Long press a phone number in Logs gave option to see last call details, and option to add to contact, this feature is missing. you can however click on Image Icon and Add to contact the number from logs though. Change of System Language is not possible as all other languages except English has been removed to make it fit into Iris501 Airplane Mode Button placement in Notification Widgets is very bad and is prone for Accidental Touch Lots of options from Settings for display, system settings have been removed to make it run on 512MB RAM GPS bug, if you enabled A-GPS, used it and closed GPS from Notification Icon, the GPS Icon in status bar is left visible, no matter how many times you turn on or turn off the GPS, this Icon keeps on displaying and a Text in Notification "Location Set By GPS" Screen Brightness is way to sensitive in Auto-mode, might Irritate you with very very fast change of screen brightness, I use a APP called "LUX" to make it stable though. Camera Will Save pics to Internal Memory and you cannot Save into SD CARD, all you can do is to move files every couple of days from SDCARD0 to SDCARD I've not checked 3G Policy, still I doubt the Data Connection is Configured to Sleep and waits for Wake from Device or push notification as screen shows data connection enabled message a lot of times while I am on move using 3G. Many Stystem tweaks are not done by LAVA, and memory management is not properly done. Root users should be able to do it, and I'll post a tutorial about this in a couple of days.
So far so good, this ROM is good, but could have been better.
may be its a very smooth and Good rom for Non-root users, but personally I squeeze the rom to fit my taste and things which can speed up my needed activity on phone.
This rom is still worth the pain to download and install as there's certainly a lot of improvements in system performance and stability.
Maps works great, Google Now is good and intuitive, Gmail syncs 24x7, Earlier ON ICS I had to keep switching connection to keep it working.
Anybody still having doubts whether to install or not, Should certainly upgrade, at-least if not all, most of future apps would work as you are on latest build of Android as of this day.
^^ Dr.Saab, this is a tough question.
normally warranty should not be lost, cause the link is of Stock ROM, which is un-touched by outsiders. and non-rooted
But if service center wants they can confuse you that its your mistake, blah blah blah
A friend recently got his phone updated in service center, they didn't provide any documents for this update, so If the phone gets defective at a later date, he has no proof whether he updated on his own, or from service center.
how to load drivers you have linked.
they fail to install on win7, if i right click and try to install them,
Also the firmware upgrade option doesn't load anything to my phone.
Thanks for your efforts Kamal Ji.
After scratching my head for few hours, I finally updated my Lava Iris 501 to Jelly Bean 4.1.1
The New boot Logo is Good.
System feels smooth, now time to root and restore my backup.
for anybody who's having trouble with SP Tool failing to detect your phone, you can do this
After the checksum error, connect your phone, While phone is connected and SP Tool Still trying, goto device manager and select "add a legacy device"
now select com port and select the Mediatek drivers you downloaded from the link on first post.
it would install the mediatek port and once you done this, SP Tool will start uploading the firmware to the phone.
Make sure you do not touch the phone or cable during the update process, any interruption to USB link between PC and Phone at this time can BRICK your phone.
The update would take 3-10 minutes depending on your PC and USB speed.
Good to see again.
You seems to be very helping the Lava Iris 501 Guys. I wish i was in kanpur, could have met a interesting person like you.
I am from Allahabad.
Downloaded the files from links you posted before 4shared.
Will be flashing the phone in next hour.
For Fahad phone: I doubted this as I've earlier had very bad experience with U.P. Based service center, not of Lava, but the young guys these centers hire are too fast on keyboard, and never think of saving a second to save customer's phone/data.
Its good Fahad got new phone, hope he'll chime-in here sometime soon.
