G1 Won't Fully Boot - Backlight Only

Hey there. I've found some similar threads, but nothing exactly matching this situation, so I thought I'd post:
G1, running Cyanogenmod, though I'm not sure of the version. Latest update notice said there were 11 updates available. ( i know, but i couldn't upgrade my sd card yet)
Issue: Phone was fine, but then battery was accidentally removed while powered on (was cleaning camera lense).
Now, Phone will begin booting, and get to the skateboarding android screen, but after that it will just hang, black screen with backlight on.
Home+Power boot will go to control menu. Power + Camera goes to correct screen, also.
Is there any way to fix other than a restore? I can restore if needed, would just rather not since it's always a bit of a pain to set it back up.
thanks for any info! Other issues like this seemed to be posted in this forum, which is why i chose it. please let me know if it should appear somewhere else.

just goto recovery "home + end key" and wipe data + cache + ext and reflash everything. or you cant goto console in recovery and try fix_permissions. it might help

thanks for the suggestion! Trying to do the restores and permission fixes, I've realized that the issue was with the SD card. Apparently it's died on me :-/
partitioning a new SD card got the phone to boot again with all my settings intact, but unfortunately none of my apps.
I hear that the common problem with sd cards is the controller stopping working; does anybody know what my options are for trying to recover the data on it?
Thanks again for the help

I reinstalled my OS on my phone to fix the slow down issues.

but it didn't seem to fix the sluggishness of things. I had thought I did a fresh install but when it booted into the new OS (cyanogen 5.0.7) it still retained some of my old settings and icons on the desktop. Well this doesn't seem very fresh to me and I am wondering what can I do to fix my problem. I know 5.0.7 is experimental but it's still acting the way it did before the install. What can I do to wipe everything and start completely fresh?

You have to boot into recovery mode and to a system wipe which will clear out the cache, your settings, call history, texts, apps installed on the internal memory, etc etc. It sounds like you just reinstalled the ROM without wiping which doesn't do anything regarding getting rid of your existing settings.

I have done that but it doesn't seem to wipe everything. I do that and boot back in the OS and there are still some of my apps I had before still installed. I have another problem too. Mine is a rogers phone and when I rooted before I seem to have installed the wrong version because instead of the rogers logo during boot up it is the T-Mobile G1 logo. So I installed the US version by mistake. I do not remember what part of the install is responsible for that part of the software and don't know what to do. If anyone else knows how to fix that I would be grateful. I want to start right from scratch so it fixes that too. Thanx!

Well I'm pretty sure there is a good and solid reason that there are two different versions for the US and Canada. I would image all your problems are associated with the fact that you flashed the wrong version.
I am not sure what the fix is, maybe somebody else can weight in?

yeah...I can just re-flash it...I'm sure that's possible. The real question is...wtf did I even flash to begin. What's it called?

[Q] [HELP] A very weird problem with X5 Pro

Have searched the forum and couldn't find any discussion about a similar problem to what i'm having with my phone. This is super weird.
I'm on an official B928 rom. It started some time ago. Whenever i reboot my phone it "resets" to a particular state. Which means - everything i do with my phone before a reboot gets reversed back to a particular state at which my phone "froze". If i delete sms, they come back, if i install programs they are gone, if i uninstall programs - they come back and so on..
I've tried to flash B928 and B552, but i always get an error at the second stage (have tried all possible combinations - with/without the battery, formatting the card). Pink screen is blocked - can't unblock it, because my phone deletes the necessary files after reboot. Can't install CWM for the same reason.
Is that it? I'm out of ideas. If anyone can throw any idea at me or direct me in the right direction i would be very grateful.
Thank you

reboot recovery
advance menu
format /data
take a look if it help

I only have the standard recovery, not cwm, it doesn't have advanced menu.
But even if i try the wipes in it, it does nothing, meaning it doesn't even delete my data.
Thanks

I'm having the same issue with my u8800-51. My thread is here http://forum.xda-developers.com/showthread.php?t=2331209 but no suggestions therein have helped, yet.

Ok, i see. I've seen some people restoring their phones with Acronis, but for this you need a working pink screen, which is a no-go for me..

When WiFi is turned off I get 'Unfortunately System UI has stopped'

This is on two standard Galaxy S5's, with standard ROM, etc - not rooted, or anything else.
Every time I turn off WiFi, or enable Mobile Hotspot, I get 'Unfortunately System UI has stopped'.
To fix I have to Power off/on the phone.
(Turning on WiFi is no problem, just turning it off.)
I have gone into 'Safe Mode', and same issue, so it looks to not be a bad App.
I have also uninstalled 'Google' updates, and again no change...
Any thoughts?

All of a sudden my S5 showed the exact same error message for no aparent reason... I didn't do anything, and now I can't use my phone at all because of that bug. It happens on every boot so I can't even unlock my phone. Tried reinstalling everything, ROM, recovery, kernel, with/without root = still same, what just happened here??
EDIT: Same thing if I'm in Safe Mode -_-

Seeing noone knows a solution here's what I did yesterday.
1. Backed up all my stuff from internal storage to the sd card
2. Did factory reset in TWRP recovery
3. Flashed completely stock official firmware from Samsung
4. Waited for it to boot up and try to restore some of my settings (it restored all folders on their places, made same amount of home screens as I had before the reinstall and downloaded all of my previously installed apps from the Play Store, ofcourse without the cracked ones, and it also restored most apps' data as well so it's not as bad as you may think to factory reset and reinstall everything)
5. Started rooting, flashing TWRP again, installing Dolby Audio, Xposed and everything I had before, took me one full day to set it up as it was before.
Now when I set it up I always make a nandroid backup from when things are working fine, in case it goes crazy for no reason again... Good luck!

when the wifi radio is acting weird, a dirty flash of your current ROM susually fixes is as its probably a radio issue. Id do that before doing anything drastic like the boot-n-nuke Odin flash and starting from scratch (which will fix that issue)

I don't think I have a ROM issue, as I have two S5's, and both have the same issue... and both are standard ROMs.
I will do a factory re-set on one at some point, but this looks to be a 'simpler' issue.
I have tried a full Cache delete, as well as other 'clean' processes.
Nothing works.

I tried to re-flash my stock ROM as @youdoofus said but still had that annoying popup. Try everything you can think of, if all else fails, reset.

well, you can wipe cache, and dalvik 3x each (not kidding about the 3x each), then dirty flash the rom, pray to the gods of android, reboot. If failure occurs, its Odin Nuke time unless you want to try to flash an individual radio file by itself (not recommended)

Fingerprint reader suddenly stopped- was working this morning!

My phone rebooted on me today while using the flashlight (something that occasionally happens from time to time), and now my fingerprint reader doesn't seem to work.
It says Fingerprint Hardware Not Available when I try to use it from the lock screen. The actual hardware itself is working, as I can still go into settings and try to set up a new fingerprint, it will vibrate and show that I touched the sensor as I move my finger, but then it fails at the end saying "enrollment not completed".
I also can't delete any of my saved fingerprints. It seems to get stuck trying to delete when I click one to remove. I'm thinking some sort of security thing got messed up when it rebooted, and I don't know how to fix it. I am rooted, so I already tried wiping cache and dalvik from TWRP. Not sure how to remove fingerprint data and start over... is there a way to do that?
I'm running the latest PE rom (flashed last week), and no, I didn't flash from Nougat in case anyone thinks this is that common issue some people have. I would try the fix for that, but since it isn't the cause of my problem I'm afraid it might mess things up more. Would really rather not hard reset again, took too long to get my phone set up with everything and paired again.

Reflash PE. If that doesn't work do a clean flash.

Boot into TWRP
Go to advanced>filemanager to acces the files in your phone.
Enter the folder /data/system/user/0
Delete following files: ./fpdata/user.db, settings_fingerprint.xml
Reboot to system and set up new fingerprints with the fingerprint wizard
Everything should work normal
