[Q] CM7 and Rom Updates

Okay, I have successfully rooted my inspire 4g and installed cm7 killer llama v2 on it.
However, I am now interested in updating to the latest RC or nightly of cm7. To update would I simply launch Rom Manager and install the rom that I wish? Do I need to wipe my phone before/after the new rom is installed? For backups I already have titanium backup run and I have titanium sync back it up to dropbox.
Also... is it worth bothering with the radio or kernel versions? Or does the kernel change with each rom?
Thanks in advance for all of the help.

1. Download CM7 RC4 from ROM Manager, but don't flash it from there, as this is more of a chance of a brick, due to the CM7 you're running being customized, go into ClockWorkMod, and choose wipe /data and wipe /cache. Then find the folder the downloaded update is in and use CWM to flash it.
2. NEVER backup/restore system data in Ti Backup between two different ROMs, it will mess things up.
3. Sometimes the kernel changes. (If something needs fixing, or if the dev is just improving the kernel and its capabilities)
4. If you have Radio S-OFF and ENG S-Off I recommend the 12.41.60.19U_26.06.04.14_M radio for all gingerbread ROMs.

Okay, thank you very much for the detailed reply. So if I flash a new rom after wiping data and cache, will I need to reinstall and reconfigure all of my apps?

NO you don't HAVE to wipe but I would recommend it. Gives you a good clean fresh start. Just back up your user data with titanium or whatever your favorite backup app is and restore it after you reflash. Just don't restore system apps or data.

I second this based on the number of people in the Viper XL thread who didn't wipe beforehand and ultimately had to go back and wipe after facing reboot issues, issues with apps crashing, and other issues of sorts. The best way to guarantee a stable install is just start fresh and restore user apps as mentioned.

Pac-Man 4.2.2 Rom Question?

Hi, I am currently running stock TouchWiz 4.1.2 ROM, using CWM Recovery, I tried to install the Pac-Man Rom, but after phone rebooted it kept hanging on the PAC-MAN image with the ghosts, phone hung there for a bit, tried to reboot "removed the battery", went back to CWM Recovery, reflashed the Pac-Pam ROM and latest gaps, rebooted phone and the same thing happened,at some point it wiped out my CWM recovery, so I got fed up and reinstalled the TouchWiz factory 4.1.2 image using ODIN, had to reload all my apps and what not.
I want to give this one more try, but do not want to go through all this trouble again. I did a casche wipe and devlick cache wipe, but no data/factory wipe "heard people had success with a dirty flash routine", do I need to do a factory/data wipe for this to work.
I am not new to flashing, but have not flashed a non stock ROM yet, kind of leary after the PAC-Man fiasco, by the way what do you guys think of Cynogenmod or AOKP. Do I have to wipe all my data every time I try a new ROM. Is there a stock, pure android JB 4.2.2 ROM out there. Thanks again.

You have to wipe data/factory reset before flashing. Two different bases. One heavily nodded framework to stock(ish) won't work. Also, if you use something like titanium backup, you don't have to worry about losing things as much.

He is saying do not dirty flash ROMs you MUST do a factory reset as none of these ROMs are the same. By dirty flashing you are flashing one ROM over another which is a boneheaded move as you are likely to be stuck on the bootloader. The ONLY time you should dirty flash is when you are flashing a newer version of the same ROM.

Thank you sir, don't be angry at me, by the way it is much appreciated.

Basically. Don't dirty flash an aosp ROM over a touchwiz and vice versa

Also don't dirty flash if the Android version is different.

My advice is to do a clean flash every time, and also a full backup. Here's what I do -
- backup all apps using your choice of app - I use MyBackup, there's also Titanium, Rom Toolbox and many others
- backup all sms, call logs
- backup launcher settings
- nandroid backup
- factory reset, wipe system/boot
- make sure you don't wipe internal or external sd card
- update to latest radio or rpm if needed
- flash rom
- flash kernel if needed
- flash gapps
- setup new rom, don't let google restore apps
- install your backup app and launcher
- restore apps, sms, calls etc
- restore launcher and android system
once you get comfortable with this procedure it doesn't take long. And it guarantees a clean phone with the latest apps and new rom with no issues.

Ok everything went fine, installed the Pac-Man ROM 4.2.2. seems much smoother and faster, my first question is how do I enable car mode where all my text messages are spoken out when received, including phone calls, my other question is now my screen is more cluttered by the on screen buttons at the bottom, the back home and systems button. The full clean wipe did help, thanks again.

Random Reboots

I was on CM10.1 for a very long time, and just recently decided to flash something newer. So I tried flashing Philz recovery (had CWM), then used that to flash VRUBMF1 and VRUCML1 baseband afterwards (from this thread). Without booting my phone, I then flashed CM11 and the kitkat gapps. When trying to restore apps through Titanium Backup, I got a random reboot. Since then, I would get many random reboots, most often in the middle of a Titanium Backup restore of my user apps because it's the first thing I want to do. Sometimes the phone will reboot before even getting to the app restore. I have tried flashing PAC rom (4.3--I flashed jb gapps with this) and unofficial Paranoid Android (4.4) as well, and the problem persists no matter which rom I am running. Of course, I have tried reflashing many times.
I am also trying and currently on TWRP, but this hasn't helped. Going back to CWM and trying to restore my CM10.1 backup gives me a fail error.
Before each flash, I wiped data, and rewiped cache and dalvik afterwards too. Is there a problem in my flash process? What can I do to solve this issue?

Google Maps reboot my phone on any ROM that I have tried for 7.X

Everytime I try and use Google Maps either flashed with gapps/bean or installed later from play store all reboot my phone. Stock does not have any issue.
Tried:
ASOP-CAF
ASOP-EX
MOTOPURE
Lineage
TESLA
I just wonder why if the stock maps app works on 6.0 why not on 7.0?? The only thing I can think of is the GPS.
Any tips or suggestions?
Thanks!

Tried nano, pico and full for ARM and Android 7
open_gapps-arm-7.1-full-20170523
open_gapps-arm-7.1-nano-20170511
open_gapps-arm-7.1-pico-20170513
also BeansGapps-Full-7.1.x-20170509 BeansGapps-Mini-7.1.x-20170509

Ok I have found that other maps reboot the phone too. Tried a GPS test app from play store and soon as I allowed it to access my location it rebooted. So it seems to be definately a GPS issue.

Return to stock by fastboot the lastest images available, flashing everything including the wipes (of course, skip gpt.bin and bootloader.bin if necessary), then take the lastest OTA's, verify operation of GPS... After that install TWRP, backup everything, and flash a ROM and Gapps, do not restore anything and test again.
I can't see how GPS would work with stock and not with ANY custom ROM...

Thanks for helping me, do you mean bootloader.img?

Ok done reflash stock, OTA's and checked gps is fine now backing up... going to use the PureNexus rom or ASOP-CAF

ARRRRRGGGGG Same damn issue... Maps crashes the phone.... so frustrating I am going to give up soon and stick with stock.
Going to try an get a logfile maybe someone can take a look at it
Thanks

ok after phone crashed the first time I rebooted a couple times and its working!!!!!!!!
Thanks to @acejavelin and @Vikas Tewatia for trying to help me with this issue.
I think one of the problems was the way I was wiping after stock to install a custom ROM, instead of just standard TWRP wipe I was using individual selections?
Anyways I am going to further test and then report back. I will close this thread once I am sure everything is working.
Thanks

The recommended way to wipe before installing a ROM is to manually wipe system, data, caches, and internal storage (kind of optional, make sure to move TWRP backups and other info to SD card first), then flash ROM and Gapps. Some people say flash ROM, boot, then shutdown and flash Gapps, but I have never had to do that.
I would be curious to see a logcat of the crash... this is not normal. Are you installing ANYTHING else besides the ROM and Gapps at this point?

I started a bug report (interactive) when I tried to use the maps again but thats when it started working properly. lol
If you know of a way to get logs from the first crash off my phone I would be more than happy to send it to you.
I did a twrp standard wipe this time rather than each partition under advanced wipe, I didn't install anything other than a ROM and either gapps or bean depending on the ROM creators suggestion and that's it!

You can use ADB to get real-time logging of the crash on your PC... Use Google to find the command.

Sent you logcat via pm thanks again!

Well I started getting random reboots in Pure Nexus ROM and so tried LOS and right away I had the reboot from Maps. I give up, staying with stock.
Thanks

Seems like one of my problems could be ASOP-CAF ROM as the version I was flashing uses a custom Kernel that has known issues with 7.1.2 and causes bootloops and crashes. The UltraDev kernel changes some things in the modem and could be why any roms I tried after flashing ASOP-CAF would not change the modem and were 7.1.2 based.
Anyways...

Well I think I have tried almost every 7.x ROM I can find and every single one has a problem with any gps app on my phone.

Check out this bug report. It might be your APNs... https://jira.lineageos.org/browse/BUGBASH-248

By messing with my APN settings as per above bug report I can use maps and have no more random reboots. Woop woop
