General :: LG E730 (Optimus SOl) Unable To Downgrade?
Jun 18, 2012
My optimus SOl came with v10e SW version.I downgraded it to v10b vodafone since newer baseband were not supported by CM7&9.Yesterday i dropped it in water and now my speaker is not working.So i want to give it to company bcoz still it is in warranty.So i downloaded v10e and flashed it.My device booted up and i also created google account but suddenly i got black screen of crash dump.Now after every 2 or 3 minute it gives me such crash dump.I can't give my device to company in this condition. I also hard reseted it and reflashed 3 times.

I SOFT BRICKED my lg e730 while trying to install HarshGinger v3.
I tried to root my phone, and everything was ok until I tried to install the rom. I saw in recovery how the rom was installing, and when all was completed the phone entered into a boot loop. I think that I should install first a stable cyanogen mod and then harshginger.. I think this is what I done wrong. The phone it`s soft bricked because I can reach to the emergency mode screen.
Question: I can do a reboot from ADB or I have to use KDZ? KDZ looks like the type of program used by the smart people and I`m not really that smart. I am looking for a simpler solution, like a combination of buttons or something.

so flash a rom but didnt like it and had to reflash my original firware. problem 1. didnt know it so i used the lg too putting in model number and imei and it told me i need V10B_00 (vodafone spain)
Flashed with KDZ no problems, Hard reset phone to exit boot loop booted to phone fine, read sim asked for pin fine, connected to network full bars fine, connect to 3g no problem all is working, EXCEPT! go to make a call goes direct to call ended. people cant call me either.

I'm having trouble booting my LG Optimus G into recovery mode. I've rooted the phone and installed ClockworkMod recovery. When I try to boot into recovery, either from the ROMmanager app or by holding Volume Up and Power, it comes up with the LG logo and gives this error: Secure Booting Error! Cause: boot certification verify. It just stays like that until I press and hold the power button again until the phone shuts off entirely. Then I'm able to boot into the stock operating system and the phone works fine, but I can never get it to boot into recovery.
The error I mentioned above seems to be a well documented error on the internet, but it seems like other people that are having the trouble are completely bricking their phones. Mine is able to come out of it. All the solutions I'm finding pertain to a phone that's completely bricked and involve taking the phone back to stock. My phone works fine with the stock ROM, but I'd like to play with some custom ROM's.

I recently did this and now I'm unable to run custom ROMs on my Optimus One:
>Downgraded baseband (so as to install ICS ROM by DaxElectro
>Then installed the above mentioned ROM and I loved it!!!
>But later found some limitations of it. (The SIM that I was using didn't let me access internet over this ROM. Other SIMs worked fine). I thought of telling to the developer about it.
>So I installed original, official Gingerbread 2.3.3 firmware V20c (India) again, through the backup created using Clockworkmod Recovery and also upgraded the baseband.
Later I wanted to show my friends the ICS ROM as they all wanted to see it. But before flashing that ROM, I wanted to try mik_os's Cyanogenmod on my phone and test it.
>I installed that but this ROM gave a boot loop error (of course I had again downgraded the baseband) I thought it is buggy so I removed and flashed DaxElectro's ICS ROM again, thought it would work fine as before.
But, now even this ROM is giving the same error!!! I'm very upset as I'm not able use it now!
How to fix this???
Yes but my official firmware is working fine and I posted this using that only.

I have a CDMA Sprint HTC Hero running 2.27.651.6 If I have read the FAQ/Stickies/Walkthroughs correctly the first step in rooting my phone is to downgrade it to 2.27.651.5.I downloaded and attempted to run "RUU_Hero_C_Sprint_2.27.651.5_R_signed_release " however it doesn't complete. The program is "Waiting for Bootloader" for about 80 seconds and then fails with "ERROR [171]: USB CONNECTION ERROR". I am able to hear the Win7 sound effect of my device being disconnected when the program says "Rebooting Device" and I hear another sound effect right after it, like it is trying to reconnect the phone to my PC but the sound is different. I think something may be wrong when the device attempts to reconnect to the PC. At this point my phone is connected to the PC via USB and the phone is now stalled on the black screen with white "HTC" logo. If I unplug the USB cord at this point I get the white screen with skateboarding Androids at the bottom (which I assume is the bootloader). The following text is at the top of the screen.

so I'm collaborating with a couple of members to port MIUIv4 from the e730 to the e739. The only difference between the two phones is the kernel.
I've fixed data, i can use Perl scripts, winrar, NotePad ++, (bak)smali and anything i can find on the internet.
Our ROM boots, but there's a screen corruption issue that needs to be addressed.
My question is: what could be causing it?
Tried:
-using cm9 hardwarerenderer
-adding "write sys/class/graphics/fb0/state 1" to init.victor.rc"
-htc one x brightness toggle.instructions for a similar problem.

I rooted my device (Galaxy Nexus GSM / Maguro) weeks ago and switched from the stock OS to Cyanogenmod 10.
Some days ago I received the (so called "stable") update to 10.1 and installed it (gapps 121212 too).
Unfortunately, the stable 10.1 turned out to be rather unstable: Apps (Google Play Music, Skype, Youtube, SMS, ...) either crashed on device startup or as soon as the app was started.
SMS frequently froze the whole phone. The former rather fast and stable device became an unstable and failure-prone device
Installing diverse nightly builds didn't improve the situation, so I decidet to roll back to 10.0.
Again, a bad decision! After installing it, CM won't boot any more. I can see the boot-image (the circle of death, as I call it by now) and that's it!
I tried to reboot in recovery mode, but I cannot switch options with the volume keys. The only option I have is to boot into the broken system...
Below the android icon it reads: Downloading.. Do not turn off target!
Nexus Root Toolkit does'nt recognize it (neither as fastboot nor as adb device).
My computer system ist Windows XP SP 3.
BTW: I don't know if this Information is relevant: The Android-Icon in recovery mode is not a lying one with its belly open but the standard 2D-Android-icon. And, perhaps more grave: Due to security concerns, ADB was disabled in my (then working) Cyanogenmod-OS...

A few days ago I got the new Facebook UI with the built-in video player+auto-play, It's very laggy (every time it auto-plays videos) and it's impossible to download the videos. I really don't know what facebook developers thought when they decided to make such a terrible update. I want to downgrade to an earlier version that still have the option to choose a video player (and download the video) and more important without the auto-play function.

i have a samsung galaxy S3 with t-mobile. i recently updated to jelly bean 4.1.2 and disliked the new gallery and a couple of other new functions so i decided to downgrade. i dl odin v. 1.85 and jelly bean 4.1.1 and started the process. it failed and when i reboot my phone the triangle warning about putting it in kies emergency recovery mode pops up whenever i turn it on regularly. i can go into the downloading menu so i know its not bricked or completely ruined but i don't know what to do from here. i did follow the phone instructions and dl kies and try getting into emergency recovery mode but it wont recognize my phone. i tried another Samsung phone and it picked it up right away.

I would like to know if it is possible to upgrade/downgrade an android phone (samsung mostly) with official firmwares without the need to root? The reason is that some testing is needed on these devices and only with official firmwares it would be valid. And at will it would be nice to be able to switch versions for different test purposes.
