Need help.

Okay for those of you who don't know, I totally bricked my phone based on a dumb decision last time and not knowing what I was doing.
I am thinking off trying to root my phone again, any advice on what rom I should root to and which is the best and most stable for the G1.

u should really go with cyanogens roms

Cyanogen's latest is pretty sweet. As long as you follow the steps correctly to root your phone, you shouldn't have any problems flashing any of the roms available. Then you can test them out, and see what you like.

does anyone know any good tuts to use to do so?

Thank you so much everyone! You all were a huge help. I have rooted my phone successfully this time and I love it!

I followed the instructions from the link on this thread to put cyanogen on my g1 but after the skateboarding android logo faded all I got was a illuminated phone I let it sit that way for 25 minutes hoping something would happen but nada so I restored a backup. Can anyone tell me what went wrong and how I can get cyanogen working?

Nobody can tell you what went wrong since we don't know what step you skipped/didn't do right based off that statement. All we can say is follow the guide to a T. The guides are the best the communitty has to offer/has produced on how to do what you want to do. If you can't follow the guide, sadly there is nothing we can do to help beyond repeating what the guide already says.

I've got cm recovery 1.4 so that step and the ones leading to it are done right, right? Then I ran the recovery, made a back up, wiped data, applied zip drc83 defanged, applied
Cm update 4.2.13 (I think 13, whatever stable version the "latest version" link give you), applied ota radio, and rebooted (automatically took me back to recovery) rebooted again, got g1 logo followed by the cyanogen android logo once that faded all the lights on my phone came on and stayed on and I had no display (apart from the backlight).
I tried multiple times with no luck. I downloaded the cm update from my phone could that of caused a problem? Everything else was dl'ed from a pc.
What's the differance between drc83 and signed dream devphone should I try that instead?

http://forum.xda-developers.com/showthread.php?t=563679
Follow the guide to a T, since you are partialy there I will tell you what you have left:
1. Download the developer recovery ROM (This is different than drc83 by a lot)
2. Download the latest CM
3. Put both on the root of your SD card
4. Boot into recovery mode, flash the developer ROM, then flash the latest CM
5. Use the "Home" and "Back" buttons to reboot the phone
6. Tada! Success!
7. Never, ever, do anything the guide doesn't tell you to do. If it says flash file X don't flash file Y because you think it is close enough. Never do extra stuff, ie if it doesn't say flash a radio by itself, don't flash a radio by itself because it seems like a good idea.

[q] nexus one not letting me get into recovery

a few weeks back i got an update from t-mobile i think it was 2.2.1. i was running a custom rom by evil, I think it was sense. it never fully installed as it came up with a black scrren with a exclamation mark and a little android guy. every time i go into recovery now, i get the same thing. this also converted the phone back to stock rom.
im sorry, but i am a newbie when it comes to flashing new recovery images. do you think this is what needs to be done? i had clockworkmod's on there before, had a buddy do it for me.. and he didnt explain to me how to fix install it lol. i do install roms etc.
any way i should go with this?

You guessed right, you need to reflash the recovery, and possibly re-root before that.
You can follow the guides in Wiki, found in my signature.

did it, having a problem installing roms now :| gonna post in that roms thread.

[Q] HTC Hero looping on the boot screen. How can this be fixed?

Phone: HTC Hero, CDMA
Carrier: Sprint
While others have reported of this problem, the solutions that worked for them dont work for me. Im really stuck.
I know, its an old and slow phone, but I was hoping to go to CM7 to get better performance out of it. Well, I must have done something wrong in the process. My current android version is 2.1-update1. I used z4root to root it and used the clockworkmod ROM manager to install a recent nightly after backing-up my current ROM. Installing the nightly failed, something to do with the zip, but my phone had already been wiped and rebooted in default factory mode. I tried doing the install again with the same nightly and a more recent one, but it kept failing due to a problem with the zips. After one of the reboots, the OS just wouldnt load; seems to be looping on the 'HTC quietly brilliant' screen. I am able to boot in recovery mode, but cant figure out how to get past this looping issue.
Ive tried booting using the back-up I created with no luck. Ive even tried going through the RUU process (cant post a link cause Im a new member here), which results in an error message stating that theres an incorrect bootloader.
I did figure out that I was trying to install CM7 using the wrong zip; had the GSM version. Ive tried installing CM7 with the correct zip, but, after reboot, it loops at the animation with the android on the skateboard and the blue arrow around it. Not sure what it means that the two different OSs loop at, what looks like, the same points.
I probably did something wrong, but Im hoping somebody with a better understanding of all thats involved can let me know if there is any way for me to fix this. Thanks in advance for the help.

I *think* your error, in general, was using a bunch of "easy" one click methods and not properly learning (READING) about what the proper steps are. Here is my advice (assuming you are still rooted) -
1.boot into recovery (power off phone, hold home button, press power)
2.wipe data/factory reset
3.mounts/storage - wipe system and boot
4.restore nand backup OR flash ROM/gapps (from the same thread)
5.reboot, and be patient, bootup could take 5-10 minutes.
Good Luck.

You are the man (or woman)! I believe the formatting of system and boot is what did it. Really appreciate the help.

It is important, as Il Duce said, that you definitely do a good amount of reading when you want to get involved in rooting your phone. You are opening yourself up to some great innovation and fun, but you can also cause yourself a lot of headaches.
Recovery is your friend. If you can get into that, at least you know things are ok. I like to wipe (or format) system, data, cache, and boot 3x just to make sure that clockwork recovery cleaned everything and there are no dingleberries from the last rom I was using.
Flashing the correct type of rom is even more important. Don't flash a gsm rom to a cdma phone and NEVER flash a gsm radio to a cdma phone. Once you delve into the reading aspect of XDA, you will see that is the sure way to brick your phone.
Some roms take longer than others to boot up. Let it run its course. Sometimes it will reboot right after installing. At some point, you might want to make a nandroid of the new rom you are running and go back to your stock (2.1 update 1) and update your PRL, baseband, etc. (if you haven't done an update in a while).
Have fun, that is the most important part and we seem to have a lot of it here in HeroC XDA land.

You know, I put in a fair share of reading about how to update the ROM on my phone and I was under the impression that it would be fairly simple. I figured that since this has been done for quite a while and all these tools have been developed, I wouldnt need to know what happens on the back end during a root or ROM install.
But I did get myself into a bind that I wasnt able to figure out on my own. And with the help of this forum, I was able to get past my problem. Im glad to say I now have a phone that is functioning very smoothly with CM7 and the apps I need.
Next step for me is figuring out how to save my apps to the SD card so that I can install from there if/when I update my ROM in the future.
Thanks again for the help!

[MOD][CWM][Bell][Gobstopper] Stock 2.2.2 for Bell Updated 10/01/2011

Disclaimer: You may brick your phone. NOT for AT&T
​
Reminder: Make sure your phone has enough battery charge to flash this, it's larger than normal.​Hi,
Here is a huge CWM zip that restores your Bell phone to stock 2.2.2. I have tested it on my phone several times and it worked perfectly, there is still the chance that something may go wrong, but I am feeling confident in it.
What this does is similar to my app or scripts, it puts my backup of Bell's 2.2.2 partitions on your phone, but instead of using dd, it uses tenfar's CWM and flash_image. Some partitions are HUGE, and take a while, your phone is not locked up.
This has been updated to include the Bell bootloader for 2.2.2 and the radio for 2.2.2.
EDIT: This has been updated again to ram fix the boot and recovery partitions if there is a ram problem.
It writes to partitions 1, 2, 4, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14, 17. 3 is left out because it's your pds partition, and data and cache have no relevant content. You must factory reset after using this to clear those. So, that's your boot, recovery, system, webtop, cdrom, preinstall, and several other partitions. This is to get back to stock Bell 2.2.2, it's not just a boot/system replacement, if that is a fruitcake, this is a gobstopper.
Please note: This restores your Bell phone to stock condition, that means you won't be unlocked, CWM will be overwritten with the stock recovery. It will be just like you bought it. If you want to keep flashing things in CWM with the unlocked bootloader, then immediately after flashing the stock zip, flash the unlock and fix zip. If you don't then you will have to reflash an unlocked bootloader, and reflash CWM recovery, which is time consuming any annoying, it doesn't mean you will be permanently locked again. I had to spell that out to the folks that don't really understand this stuff. At all.
If you want root after installing this, just install Superuser.apk from the market.
Bell_FR_2.2.2.zip (Froyo not France)
(md5 e431b4cc3ba7e3a27b6aad6982a31066)
Cheers!​Oh, I forgot to mention, this is not quite stock, there are su and sudo binaries in /system/bin. Just install Superuser.apk to be rooted. they haven't been a problem for doing an OTA yet, but they are easy enough to remove if it comes up.
unlocked-fixed-Bell-2.2.2.zip
Mirror: unlocked-fixed-Bell-2.2.2.zip​

Damn, nice work as always, man! This should come in handy for lots of us Bell Atrix users that feel left out. Lots will appreciate this!

When you say without amnesia are you talking about the bootstrap or are you talking about a user who is using the bell_ihop and then installs cwm and then reboots and looses recovery?
So a 2.3.4 bootloader and radio will work find booting a 2.2.2 bell ?

Will you eventually be able to compile a zip for Bell gingerbread?

keeping in mind that this is only for the recovery with unlocked devices, what he means is that the CWM recovery that tenfar put out has a problem with int'l phones (pretty sure it's all int'l) where IN recovery (not just the normal ROM, like the problem we had before) only 300 and some mb of RAM is available. since this zip is over 300mb, it can't all load into your RAM properly with normal recovery.
NFH found this bug, and patched recovery for us so as to fix the RAM problem. the two files attached are fixed recoveries for the two separate MBR versions of int'l devices.
to find what version you should use, connect to phone via ADB and then
Code:
adb shell
su
cat /proc/cmdline
and then search for the part of the output where it says "tegrapart=mbr:" and read that. it should have either "1100" or "d00" somewhere in it, use the CWM zip attached that has your respective output.
hope that clears up your question, if you have any further ask them in here.

Hi,
I believe y2whisper may be working on something like that. The point of getting back to stock 2.2.2 is to be able to apply the final OTA for Bell GB. Certainly something similar can be done for any firmware you want to flash.
Cheers!

i flashed the d00 and I do maintain unlock however no cwm just stock recovery with no menus.
tried it again and it work
but seems like i have to fastboot flash it each time i want to use recovery

I know what you are talking about, but I got that with a stock bootloader.
If you are going to be using CWM recovery with this 2.2.2, then flash the boot file for d00 as well, it gives you the ram fix and for some reason it doesn't cause that issue.
Cheers!
Here is an international CWM recovery, it detects the 1100 vs d00 tegraparts and installs the right recovery for it.
CWM_INT_Recovery.zip
(Just use it with whatever CWM recovery you are using now, it will update it with the ram fixed one.)

ohhh, that's a nicely scripted installer you got there. i think that would be quite handy for int'l users trying to flash custom kernels, is it possible to apply that script to select the correct boot.img out of two for the right tegrapart? if that's possible i think you should hit faux/edgan up with that script and let them apply it to their int'l kernels so users can just use on CWM to install it.

Hi,
Sure, it's just replacing the word recovery with boot and having the right boot images in the file.
Cheers!

yes its zipping now. off to bed but tomorrow I will back up my stuff and attempt to flash to see if it works.
@akurit
I forget off the top of my head but there is a file that you just have to delete to prevent that. the file just flashes the old recovery on every reboot. get rid of that and you will be fine.

Awesome work! This makes it much easier to get back to 2.2.2

Its installing now!
now at some point the install stopped and I think I saw it say status 0 and then recovery rebooted. so I am not sure what happened there.
ive rebooted with no problems. and its uploading now. if someone is willing to test this out (a bit difficult for me since I am already on 2.3.4) let me know. and will send you the link. would like to see a proper install before i share it with the masses.

This is why hehee

i could test it for you, i should be able to tell if it works alright or not, since i'm starting from an AT&T build of 2.3.4. would i have to head back to stock Bell using Gobstopper before i use your package too? i got a whole buncha time on my hands this week, so i should be able to test it however you want.

anyone try flashing the bootloader and radio?

Hi,
I have tested it, no problems, but went back to IHOP and the ram-fixed bootloader for 2.2.2 in the OP so recovery will work.
Also, the file install_recovery.sh located in your /system/etc/ doesn't exist in the Gobstopper, so that isn't causing recovery to be generated by patching boot.
Cheers!

So its when flashing the webtop that the install stops with the error code. when i boot up all is ok but a reboot later and recovery is gone (as in you select it and it just boots into android). reflashing cwm recovery fixes that.
I have tried swapping the webtop files to no avail. going to keep trying. any ideas are welcome

Hi,
What recovery are you using, if it's not ram fixed you are going to run into situations where you don't have enough space to flash it.
Cheers!

ahhhh.
you know i was wondering if that was it. I even repackaged the recovery thinking it would be the cause.
I don't believe I was ram fixed at the time of the backup. So I am thinking either, have custom recovery flashed in that spot, or change the order to where recovery gets flashed after.

[Q] only boots into recovery

ive had the phone since at&t had it on display. rooted it and had various roms for the last couple years and never had any serious issues. last night i flashed jellycream v2 and then did a factory reset inside the rom. the phone prompted that it would reboot twice and that it was normal. it rebooted into twrp and did nothing afterwards. i rebooted it from the recovery and all it did was reboot back into recovery. i decided to flash a different version of twrp and still the same. then flashed clockwork and still got the same result. i wiped the bootloader and basically went through the rooting process again. flashed the latest version of twrp and the phone is still only booting into recovery.
i am at a loss because this is as far as my knowledge goes. its like the phone is stuck still trying to wait for that factory reset from the jellycream rom or something and it wont do anything else but load TWRP.

If factory hard reset will not work (with phone off, press power and volume up together for some seconds. You might want to try also holding home on the touch screen.) flashing firmware will fix it unless you have hardware failure, which I doubt.

so far i get the grey LG screen with 'booti mmc_read xxxx' at the upper left with the hard reset. it only takes 2 seconds to show up but the phone shuts off if i continue to hold the power and volume buttons. ill read up on that link here.

I missed that you wiped bootloader. You need that . So you could maybe just install the wkpark bootloader in recovery. You would do 1 and 3 here (1.25a file is down the page)
http://forum.xda-developers.com/showthread.php?p=39130435
I think Jellycream actually requires you have it, if I remember correctly.
Not sure why factory reset would cause that issue, but it will definitely not start without bootloader.
Flashing firmware will also write the (stock) bootloader if that does not do it. It will also reinstall the OS if system is corrupt or missing.

I can't find the thread for Jellycream2. Would you post a link? Are you sure it is for P920/P925 (same device, one is AT&T branded. I have the Thrill P925). If it is not for those device numbers, you may need xbsall's unbrick guide.
Also, if Jellycream2 is based on ICS and you were on a GB ROM, you would likely have needed to first upgrade to ICS and then install the ROM.
I'm just trying to understand why a factory reset could brick your phone...

ok basic rundown of what i did in the last year;
when first played around with rooted it about a year ago i used all-in-one to do it. i had already upgraded to ics using the lg mobile support tool prior to rooting. rooting went off fine until i installed a Beats Audio app from the play store. when the phone rebooted after it would be stuck at the grey LG logo. i didnt know what to do so i used twrp and wiped the whole phone. then i used all-in-one and flashed the ICS bootloader and did the flash kernel 4 fix or something its one of the last options to do. then using twrp i flashed ICS_V20_P20, Stock_V20P_Rooted, and a Thrill Update, the phone rebooted fine in an ICS rom but it ran like complete ****, so i tried various roms and the one i settled with was called OptimusRS V1. i used that up until 2 days ago when i flashed the jellycream rom.
after i factory reset that i tried to flash the different wkpark bootloader and twrp that came with the megatron tool hoping that would fix the issue. but it did so i reflashed the original twrp and ics bootloader from all-in-one.
failed to mention this before but i tried 3 different recovery files in between each attempt and it would flash and reboot fine but the phone would still do the same thing and just load recovery.
ill find links when i get off work today. thats the basic history of the phone though.

Hmm. Stil not sure then . Maybe a corrupt zip or you wiped something important. Flashing with LG Flashtool should recover it. And always make a Nandroid backup before installing anything from recovery.

http://forum.xda-developers.com/showthread.php?t=2392309
thats the jellycream rom.
im downloading the files for your xbsa rom at the moment. i do remember yesterday when i used the megatron tool i saw an option to flash the stock bootloader and recovery. i tried it but all i got was the pink LG logo then a security error message below it and the phone shut off.

Oh, ok, OptimusRS's ROM.
Hmm, I thought v20 was GB or something... If it is not ICS then that would be the problem. Also it does say there you need wkpark bootloader for that ROM.
Also, xbsall's v28B includes recovery but it is in system partition. I don't know if that ROM requires you install it from recovery partition or not.
If you still want Jellycream you should be able to flash xbsall's ICS v28B (the normal partitions one, not large partitions), then install wkpark bootloader 1.25a in recovery, then the ROM.

well that breaks down that a bit better. my progress at the moment is step f6. when i connect the phone nothing installs though. it just reconnects and disconnects every second or so. im guessing its because i already have those files. dunno though. i cant get my pc to install the adb drivers for the life of me when the phone is connected in recovery mode.it sees the new hardware just cant find the files.

actually i got it. for some reason the phone wouldnt install anything until i put the battery back in at that step. i continued successfully to step M. the phone is setting up my google account at the moment.
will flashing the baseband be necessary if my apn and sim work like the phone is now? my provider is h20(canadian i heard) but im the usa.
HUGE thanks regardless

Cool :thumbup::beer:
The no battery part is just for driver install, which is fiddly for this phone. Sometimes trial and error is a factor.
The baseband you have now would be the one you had previously. If it works, no problem. The one in the v28B pack is supposed to be optimized for the v28B .bin file, but hey, whatever works.

im only getting E for data. i tried to flash a baseband meant for at&t but it says failed after about 90 seconds. still no 4g though. i did flash the xbsav8 before i set my apn up. i might just go with an optimusRS rom again though. i was happy with it. probably not jellycream this time.

Baseband fail after 80 or so sec is normal. It means it worked. Check your baseband in android settings/about phone.
You might try speed test app to compare actual speed. ATT 4G icon is a lie on this phone IMO.
Now that your pc is set up you can flash any P925/920 bin. Kdz files (combo of bin and fls, there is another tool for flashing those files) can be extracted into separate bin and fls, but I have not done it. The advantage is you can flash baseband separately.
Xbsalls vX3D (see his page) with the P925G fls file gives me 4G icon on Straight Talk in the US, but I like his vR3D better, and I can't tell a speed difference, honestly.
I have not actually measured the speed in either, however.
And for either of those ROMs, you must flash his large partition version of v28B first...very important.

oh its definitely like 2g speeds. its pretty slow. i tried using my providers app and website and its saying the phone i have isnt registered to them anymore so it might be just that. if thats the case ill just bring it in so they can do that for me. when i rooted it the first time i wasnt getting any data and they had to re-register the phone to get it to work right.
my baseband says OMAPP4430/XMM6260. for comparison and/or confirm differences. i have no idea lol.
side question though; my sdcard still has recovery files for the optimusRS v1 rom i had on it. i really liked the setup i had when i made the recovery for it. Im tempted to reinstall it but im really not too sure if itll work or worse harm my phone again.

Lots of variables, but you must remember that xbsall's P940 recovery app he he uses has recovery in system partition. The recovery you had before was probably in recovery partition. They write restores from two different places. Probably you would get an error, but not positive. Understanding that may take some Googling...
If you try it, back up before trying to restore the old backup. Then you could hopefully restore if the restore fails, know what I mean?
Probably the safest thing is to use the all in one tool to install recovery in recovery partition and use that one to restore backup.
I do know when I have restored backups, I have wiped Dalvik, Cache, and Factory Reset (in recovery) and then restore. Then it works. Some people wipe system too.
You can usually flash to recover from a problem, but then you have to set your phone up again

Well I recovered everything. All settings and personalized stuff. Just everything. Everything is running normal again. Just now my data is saying im using an h20 microcell instead of just H20 with a 4g connection. This 2g stuff is for the birds. I'm almost thinking the firmware we flashed has something to do with it. The phone is functional though. Just slow and no mms. I haven't been able to find much on the forums about it. I'll poke around more tomorrow.

I'd try another baseband.
