I recently bought lg optimus net p690. It was running very good. I rooted it 3-4 days ago. There was no problem after rooting. It was running the same good. But while using wifi I ran the "software update" from phone. It downloaded an 18MB file and then updated phone and restarted. After that my phone has become very laggy. It runs slowly. When I slide to change homescreens, they change very slowly. applications too are laggy now. sometimes they crash...
now I want that previous firmware that was running good.
I tried to reset my phone (settings>privacy>erase) but nothing improved (my apps got deleted ).
I dont remember what was the previous firmware version or any thing.. but this is what is displays
Android version 2.3.4
Software version v10e-Jan-06-2012
How do I roll back to the previous version of firmware.. pls help!!
Only death can not be fixed.
How do you know that you downloaded a new fimware or just some application updates?
Did you take note of the software version? (Under Settings/About/Software).
Did it give you any warning about losing your Apps? (Titanium Back-Up is for backing-up Apps).
You can not "roll-back" firmware if you did not do a ROM (also called nandroid) back-up first...
But don't dispair, because If a ROM is not working for you, wether it is stock (Manufacturer) or not, you can get something better here!

Cheers, and don't despair, rooting is just the first step to a long and fun path!
BTW, you might have to root it again, but you already know how to.

Opps.... Forgot to ask... Did you do a "reset" (Hold Power down and choose reset phone)? A simple reset can solve A LOT of things, better than just pulling the battery out, so try that first and let us know what happened.
Again, you have to ENJOY getting into phones. You will learn a lot while failing and trying again!
i did reset from phone settings. not a hard reset.
it displayed "updating firmware" during the update process.
where can i get custom roms for lg p690? i dont know how to install them. pls help

Odd - I had an update last week on unbranded UK HTC Chacha but my new version number is
1.54.401.3???
i got this update yesterday (it wasnt in there about month ago) .but like jporch my software number is 1.54.401.3 .i guess it's because my rom is european (even though im iranian ) like yours,jporch.
an interesting point is , i had this known "dialer" issue, too .but it sounds like it is fixed. the dialer application was on 98% before the update all the time ; no matter what common fix i applied ( eg turning on the bluetooth,check off those three options(fliper and.. ) in Setting>Sound ...) but now it works ok . it's on 3% (even without those quick known fixes i mentioned.but i havent measured the time that battery can hold on since i updated it yesterday.
still no fix for the internal memory.
these are my experiences with this new system update.
Hello.
I had update software and now WiFi doesn't work. Any help???
Which version was before, I want to go back to it. Now is 1.54.401.3

i have no idea why.but i would suggest a master reset if the other members has the same opinion..?
---------- Post added at 10:18 AM ---------- Previous post was at 10:05 AM ----------
and btw , my phone dialer again went wrong to 97% again after a day. i dont know why ! and the day after that it went back to 49% !!!! (which is between 97 and 3 % ).the only thing that im suspicious of is this fix that i applied (pm setInstallLocation 2)
Yeah - i checked dialer imediately after i updated and it went straight to 98% - since then its been on 49% exactly almost every day since????

Okay ill run it later. I've not done anything else just rooted. Recovery is all stock, ROM is stock etc. Just rooted the stock ROM for Link2SD.
Hope this works !
Can we get any improvement from HTC in this new ROM
I ended up not running this update. I found out why it was crashing and fixed it. I'm afraid to update and lose root, apparently you can't go back.
I was really worried when dottat said that many non verizon cellular users did not get cell service after lolipop update.But I am happy to inform that u can update it using htc sync manager and there is no issues with cell phone service etc.Its absolutely fine.There are only 2 issues which we all are facing from 4.4.4.Unknown sim card icon and Portable hotspot setup same issues. Just wanted to know from senior forum members whether you are facing android is upgrading message after you hard reset your phone. Becoz After updating My phone showed that it is being upgrading as in optimising apps around 279 apps. After i wiped my phone and again same process after reboot.Any one else having this kind of process or its just me
I also can confirm this.I wanted to root my phone,but two days ago i connected my phone with computer and HTC Sync Manager showed me a notification for update.
Same here
I just updated to lolipop and found apps updating for more than 15 min, but i found that its normal process which takes in htc one m8.
try to uninstall bloatware using root uninstaller, so for next time u can reduce the apps updation for some time.
---------- Post added at 11:20 AM ---------- Previous post was at 11:17 AM ----------
u can very well root ur lolipop htc one m8, update it with official firmware, then use fastboot commands to install latest recovery and then update it with super su, Now ur rooted.:good:
After a run in with a couple of apps' who's developement ran out with ICS 4.03 (VLC Media player and Tesla paid flashlight),I managed to recover once (VLC),but after Tesla I couldn't.
Along with usual house cleaning after root,I did Uninstall KNOX and it's buddies ... 4 in all,IIRC.
Chrome Cast is also gone.
Here's where it seems to have gotten weird: when I put in Tesla the instability got so bad that I was forced into a factory reset.
There went my root.
Upon trying to redo it,I can finish the first step of rooting,but the second step fails.
I'm guessing because of KNOX?
I have older backups,but I can't boot into recovery to access them ... no TWRP.
Any ideas on this one,or am I looking at sending it in for a reload?
Any help would be appreciated.
No ideas?
No idea

I wish I could help
No problem ..... I'm running 5.1.1 now.
MUCH better than 4.4.4 and just as easy on the battery..... snappier too!
I think it's the T Mobile ROM.
I had it installed at CPR in Novi,Michigan when I was down for the Woodward Dream Cruise.
Now to root!
Not sure if they're up to that point yet?
I've even turned off KNOX active protection .... it's in the settings.:highfive:
No TWRP and no back up accessable
You can download the stock Firmware from [www dot sammobile dot com/firmwares. You will be able to flash this using Odin and will #1. Restore you boot loader to factory. And #2. Will restore you KNOX, which will show un-altered. From here of course install your TWRP and should be able to proceed as normal.
I looked and it seems they're only offering 5.1.1.
My question would be:can you go back to KitKat after upgrading to 5.1.1?
If I could,where would I find the ROM?
Lastly: I like this system much better than the stocker.
The downside is the O/S uses around 1 gig of memory.
THAT'S BLOATWARE!
I've got 34 app's disabled right now.
I'm thinking it'll easily be under 430 megs once I get rid of the garbage.
So, I rooted my S7. It worked fine. One day, randomly out of no where it bootlooped (Google play services crashed. I restarted phone and it bootlooped. )
I have not made a single system modification other then rooting it. Didn't mod anything or mess with system files, and I had barely even been using the phone when it happened.
So I unrooted it (The phone still gave me the "Custom" symbol though) and Just now-- It randomly restarted. I didn't restart it. it just did it by itself. And it came into a bootloop. I don't understand why. What can I do to fix this?
MORE SPECIFICALLY: By Bootloop, I mean it stays on the T-Mobile screen and vibrates every minute or so and does not do anything (I even left it alone for ~ 30minutes and it never got past this screen)
Factory resetting the phone fix's it, but I don't want to factory reset my $400 phone every week! I don't understand how I could fix this either.
What method did you use to unroot? Did you flash stock firmware with odin?

All I did pretty much was flash stock s7 firmware. (More specifically boot.img)
Originally couldn't find a stock s7 image then I just used one I already had and it worked fine
EDIT: Flashed the entirety of G930TUVU4APK1 firmware, (Rom and all) Hopefully this will fix my issue and stop it from happening but if Anyone has any ideas or suggestions, I'm all open

Just now noticed wat your problem is sorry for being late so yes to fix the bootloop refladh stock firm and when you go through all the root steps install xposed (yes it's possible it's insane on how they got it to work but it's possible I've done with my self)after getting xposed installed through flash fire go to xposed and get xtouchwiz something it's a blue gear install that And it will set your system status as official

Here's a quick explanations of wat i think it is it's becuz you've ether heavenly been modding the phone or if your phone status is custom then that's the problem I had with mine after asking around someone gave me the fix i put it in the other comment hope this fixes your issue it worked for me 2 months of no bootloop I switched to 7.0 vzw beta so I lost root
Every time I install a rom, the device does not want to boot up. It loads the Samsung J7 logo, then goes black. Waiting for a long time does not work. I've waited for an hour to no avail. I have tried Alpha Centauri, Nameless 3.5, SyneXOS and all do not boot up. The aroma installer loads up correctly in TWRP. I have tried downgrading TWRP, wiping phone clean before installs, different downloads, and even reflashing stock FW and reinstalling TWRP. my phone's baseband version is J700FXXU4AQD1, just in case someone asks for it. I have yet to find out a way to get a log of the system while booting, as it may help uncover why so. To my knowledge, this phone may be SIM locked, but I have yet to confirm. Feel free to ask for any more necessary info. Thanks! <3
I have the same model fon and all those roms boot for me.
Maybe use a fresh flash disk - only ROM zip no other files / folders, and do a FULL wipe before flashing.
As usual keep a backup of EFS and Radio folders.
Latest TWRP is best. Battery > 90%

Battery dead? Or too weak to get beyond splash?
I did something awhile back (phone was unrooted and 100% stock) and it refused to charge or to boot beyond Samsung splash screen, and of course the battery was drained, so ZERO way to get phone to turn on as it'd instantly shut down. Happened after doing a win7 windows optional update adding Samsung usb drivers or something. Phone was charging via usb I sometimes have connected to the PC, hence windows update detected the phone and suggest the driver. I don't know exactly what wrong, but it'd loop constantly when trying to charge. Pulling the battery and reinserting fixed it.
Also, fwiw, I just had to do a factory firmware reinstall on a rooted J7 after mistakenly turning off the developer options. It was fully locked, including recovery. I used the giant 1.4gb zip from Samsung (had to join the SamMobile BS to get the file) that ballooned to 2.5gb unpacked, that was exactly for my phone. After flashing that with most recent Odin, phone is back to it's pre-rooted state, replete with bloatware. But all files (pics, etc.) are still there. Maybe try that if battery isn't at fault?
Yes, I too have experienced that stupid "non charging" charging on the usb port.
@aMega329 make sure your fon is not connected to a pc / laptop as you flash ?
Sent from my SM-J700F using Tapatalk
Ok. thank you for the tips. I am now going to try flashing the rom now. I will update soon.
UPDATE: nope. no avail. Fully wiped, battery at 95% at start of flash. Not plugged in to a charger nor a PC. Formatted data partition after flash. Reflashed 2 times. Guess i'm SOL for custom roms. :'( Stock works tho.
Hmmm ..... , I thought just wiping the data partition is enough. Why are you formatting?
I don't format ever!

Are you sure J700FXXU4AQD1 is marshmallow 6.01? https://shell.boxwares.com/Download.aspx?L=1250
You need to be on MM first before installing these roms.
I'm on 5.1.1... hmm. I'll try updating f/w to 6.0.1 first then doing everything again. Thank you for the idea though. I'll get back soon after i flashed 6.0.1. Man, it'll take forever to download that.
www.updato.com is your friend for speedy firmware downloads.

Okay. So guys, I finally got Alpha Centauri to boot. What I did was i downloaded a MM firmware for a J700F in another country, then flashed twrp and the ROM. Thank you guys. I guess our telcos just suck for delivering OTA's to our devices.
For people who have this problem, make sure you are on MM firmware first. If you can't find MM firmware for your device, such as my case, just use firmware from another version. It works for me, but if you doubt it, it's worth giving it a shot. I used J700FXXU4BQI2. Luckily, my Wifi, BT, and mobile data still work nicely.
Congs!
