G1 stuck at boot screen, after radio rom upgrade? Is there solution?
can you enter recovery, fastboot, what spl do you have, did you flash the spl first, what file did you flash, what type of phone do you have (region). Did you try to wipe and reflash?
I hope what you flash was truly a radio not an SPL.
any news on this yet??? man you should ALWAYS know what your doing,
if in DOUBT, get on here and SHOUT
flashing stuff you dont know is a quick way of bricking your phone but i have a feeling i know what you have done here are you trying to flash CyanogenMod if so what version and what version are you flashing from?
brit
Please igord? Share with us what happened? Is it bricked? Where was a mistake and which tutorial did you follow? Thanks.
The same thing happened to me, I was trying to root my phone last night and when I flashed the Danger SPL the phone installed it and requested a reboot. Rebooted and now the phone is stuck on the T-Mobile G1 screen. Tried to boot into recovery, doesn't work. Tried to boot holding camera + power, doesn't work. Assumed the phone is bricked so I did the only thing I could think of...
Called HTC customer service today, my phone is still covered under the HTC warranty. I lied to the representative on the phone saying I got an OTA update and now the phone wont go past the T-Mobile G1 screen. She gave me a RMA # and told me to send the phone in since it is still under the HTC warranty and that if the tech finds out what is wrong (and considers it a "factory" problem) they will fix it at no cost. If the tech feels the problem is a non-warranty problem, they will call and tell me how much it will cost to fix. With the HTC warranty, they said they REPAIR not REPLACE the phone.
Has anyone sent their phone into HTC when it was bricked? If so what was the outcome?

did you make sure that you flashed over the new radio first?
No I didn't flash the new radio because the guy that was helping me told me I did not have to. He said the old radio would be fine with the Danger SPL. But it doesn't matter now because the phone is bricked and has already been shipped to HTC.
**Has anyone ever sent their bricked G1 to HTC under warranty for repair? If so what was the outcome?**

....you should punch that guy....its been posted everywhere that old radio
+ new spl = best/fastest way to brick
A lot of people here have sent their spl bricked phones to htc. the mainboard is usually replaced or a replacement phone is sent (usually the latter)
Yea...once I get it back I will be rooting my phone the correct way. And read more posts about how to do it successfully.
Do you know if they consider it covered under warranty though? (FREE to fix?)

Yes it should be covered. At most, they will charge a $39 triage fee
Okay cool! Thanks so much for all your help! =) Lemme tell you I was soooooo upset when my phone got bricked, because it was a BRAND NEW phone (I bought from someone off Craigslist who just had the phone sitting in the box in his closet) and the same day I bought it the same day it got bricked. That's why I'm hoping it will be covered under warranty. I'll keep my fingers crossed and keep everyone posted when I hear back from HTC once they receive my phone and diagnose the problem.
Ok... so my phone is stuck on the G1 screen... from reading all the posts trying to see if there was a possible solution I realized my phone may not be (completely) bricked????
I can NOT get into recovery BUt when I press <camera>+<power> I am able to get into another screen... bootloader I think???(3droids on skateboards) I press the <back> button... nothing happens.
HOW DID I GET INTO THIS MESS? I was trying to go from the CM pimped out recovery image to RA's recovery image because it had more features that I needed (ie..dalvik cache...)
I downloaded RA's recovery image... placed in the root of my SD card.
from the terminal... I typed
$su
#mount -a
#flash_image recovery /sdcard/recovery-RA-magic-v1.3.2H.img
#reboot
.. pressed <home>+<power> and wallah... I'm stuck.
Again... I have tried doing the search on my own... I have to admit... I only read about 10 random pages... I even did a general search on here and on google.
Please constructive suggestions are welcome...
If its bricked, its bricked I can accept that... Im beyond warranty but do have insurance.. just hoping since I can get to other screens there's still hope for MY SITUATION.
stuck @ tmo g1 screen
I was updating my radio and SPL following the guide here. I already had cyanogen recovery 1.4+JF installed, but followed the instructions as per the tut.
My phone stopped like it said so i took out the battery. I then proceeded to boot back into recovery and install Cyanogen mod 4.25(whatever the enwest one is now) and g1 will not boot past the t-mobile g1 screen.
I have adb control while stuck @ the tmo-g1 screen and I can get into fastboot.
What can I do to get my phone working again?
I tried to 'adb push' the radio update back into /sdcard/ but it says 'failed to copy update.zip to /sdcard/update.zip: read-only file system'
Fastboot says the following
DREAM PVT 32B ENG S-OFF
HBOOT 1.33.2005 (DREA10000)
CPLD-4
RADIO-2.22.19.26I
Thanks in advance

i suggest a reflash. Did you wipe before the flash?
I didnt wipe the first time. But I wiped after it stopped loading, and tried to reflash, but no improvement. Still stuck -_-;; also, is there any way to push files to my phone besides adb? I dont have a microSD reader with me at the moment so i cant get any other roms on the SD
Still, you can get it fixed (unbricked).
I'm in China and I got my g1 bricked days ago, then I fixed the phone by changing the NAND chip.
about $35 (or say RMB 250)

fastboot
You have the engineers spl now so I would suggest you fastboot the radio, erase the phone, and push over the recovery again. That would possibly fix your problem.
These are the commands:
fastboot flash radio radio.img
fastboot erase system -w
fastboot erase boot
fastboot erase recovery
fastboot flash recovery recovery-RAv1.3.2G.img (the name here changes depending on which recovery you have)
You're going to want to put the radio and the recovery in the "tools" folder of your sdk
This happened to me when I first rooted my mytouch and it fixed it for me.
Did what you said, everything went through without any problems, but it's still stuck at the t-mobile g1 screen -___-;;

how long did you wait? Also, did you flash the actual HTC android 1.6 OTA update before you flashed Cyanogen's?
So I had cyanogenmod 5.0.7 installed and I decided to try the new smoki rom, I realized I had to update radio so I tried the radio tool and all I get was writing radio..... and nothing else it just stayed there for a good 15 minutes. Any ideas?
I have the 32A and it was rooted with a gold card. I can get into fastboot but nothing else. Thanks!
We need more info. Do you have a mytouch 1.2/Fender Edition Mytouch? If so, you cannot run anything other than stock spl and radio (1.33.0013 for spl and radio 2.22.23.02)
The good news is that if you do have a mt3g 1.2/ Fender LE, it is not bricked since you can still get into fastboot. From there, you would need to make another goldcard, load the sappimg that contained the engineering spl and then flash stock radio, amon ra's recovery, and stock spl once again.
Normal Htc
Its a normal magic i.e. rogers branded without headphone jack does. Do i have to do the golden card thing even if I rooted it before? could you point me to a guide for rerooting I'm kind of a n00b
Mod. edit: not dev related, moved to general
Okay, since it is not a mt3g 1.2/Fender LE, I don't think you have to reroot. Can you boot up the phone, can you get into recovery, and can you get into hboot (vol down + power button) ? And what is the spl version right now?
HTC MAGIC
all I can do is get into hboot and fastboot when I try recovery I just the rogers loading screen and it doesnt go away. my spl i think is 1.76.2007 and my current radio says 3.22.20.17 but i did fastboot radio erase and it still shows it. I have tried fastboot flash recovery then booting recovery but it doesnt work I have also tried fastboot flash radio with like 3 different radio images and that didnt work. I'm kind freaking out because I have 0 warranty lols.
Don't freak out, it's not bricked. Don't expect to be able to flash anything if you dont have engineering spl (1.33.2010). Now, I don't have a traditional 32a magic, so this might be the best solution to your problem, however, this is what I know will work.
You need to make a goldcard again and load the engineering spl on it. (I'll look for the link in a bit)/
Then, you boot into Hboot mode and it'll automatically flash the spl for you.
Afterwards, you go into fastboot, flash whatever radio you had originally, then the amon ra recovery image, and then whatever spl you had before.
Lastly, you go into recovery and flash cyanogenmod back. Once you finish doing all of that, I'll help you get the other rom on your magic if you need help.
I'll look for the file you need in a minute. I gotta finish up my physics homework.
EDIT:
Okay. These two guides can explain things a lot better than I can. Choose whichever one you can do more reasily.

Golden Card
How would I make a gold card if I can't get the CID because the phone wont boot? Is there another way to read this information of it? I tried googleing but no luck yet
Nvm
Nvm I found the goldcard.img i'm charging my phone right now and i'll try it in a hour thanks for the help.
You can get the CID even if your phone doesnt boot. As long as you're at the boot screen, it'll connect and you can get the CID.
Unsure
Not quite sure how I can fallow the guide since I can only get into fastboot any suggestions?
tried engineering spl
I got this engineering spl ROM v2.53.707.2 (Engineerings SPL v1.33.2010) - MD5 : F9674D19BE5F949D0D9DC99714D210E3 and put it on a golden memory card but the hboot doesnt recognize it do I need to rename it? I also tried flashing radio again with fastboot flash radio radio.img with radio.img being the old and new radio still as soon as it starts writing the htc screen goes black but on and the phone becomes unresponsive
I just rooted my Mytouch a couple days ago and everything worked perfect and i did it without bricking my phone. I was trying to get the supercsdiv4 rom, but i needed to flash the lateset radio and heres where the problem started. the radio tried to flash was 2.22.23.02. I used the recovery image to flash it and then when i rebooted the phone it stayed stuck at the splash screen and i cant get into fastboot or recovery anymore. it just boot to the splash screen and stays there. I know i cant get my phone back but i want to know what i did wrong so that i dont ever do it again. maybe it was because the radio i had was a 32a radio and this radio i tried to flash might have been 32b but im not sure why that wouldn't work if my phone is 32b
here was my system
pvt 32b
Hboot 1.33.2005
radio 3.22.20.17
have you tried taking the battery out for a bit.. relax a while, then put it back in and try to get into recovery mode (home and power)
this actually happened yesterday and my phone was off the whole time so it has had plenty of time to rest. My phone is truly bricked
well im sorry to hear that, but i have no idea what you did wrong, unless you did flash a 32a over a 32b or the other way around, im sure that could really mess up the phone.
may be a useless idea but have you tried a hard reset
1. With the phone turned off, press and hold the HOME and BACK buttons.
2. Briefly press the END CALL/POWER button while continuing to press the HOME and BACK buttons.
3. When you see the screen with the 3 Android
images, release the HOME and BACK buttons, and then press the TRACKBALL.
i have no idea if it will do anything but might as well explore EVERYTHING.
Similar Problem (Partial Brick?)
Not to take anything away from clint1225 but
I have a similar problem and didn't want to start another thread.
I tried unrooting my devices using the method
described at theUnlockr.com. Everything was fine up until I tried using
their sappimg file (said it worked for all old magics).
At the hboot stage, it found the sappimg but the update failed.
However, the magic now says:
SPL-1.33.0006 (SAP50000)
Radio- 2.22.19.261
Ship S-On G.
It's a 32A version.
I had an engineering spl and 6.35xx radio before I attempted to unroot.
Oh I'm not able to access recovery but I can access
fastboot (computer can't find it though under "fastboot devices")
Other than that, it's stuck at the first splash screen.
Any advice/tips?
Sorry for the long post and thank you.
Good luck to you too, clint1225!
UPDATE *Similar Problem (Partial Brick?)*
In the adb, the serial number
of the htc magic is coming
up under "fastboot devices".
However, if I try to
flash a recovery for example, the adb
returns "remote access not allowed".
I've read about the gold card method
but my phone won't boot up properly
(stuck at splash screen) and I can't
access recovery. Only fastboot seems to be
working.
Any help is greatly appreciated.
Thanks!
Take it for what it's worth coming from a newb. But from my understanding if you can reach your phone with Fastboot your a NOT bricked. But this is what I have heard here on XDA, I haven't proven this myself.
Check around and hopefully with fastboot you can get your phone back. Good luck.
I did the exact same thing a few weeks back. I flashed a 3.22 radio over my 2.22 radio, thinking it's an upgrade but after it reboots, it wont get past the logo screen. I spent the whole day trying to find ways to recover it but cannot find any. Thank god I have warrenty on it so I went to the Tmobile store, told them I updated it and when it restart, it got stuck on the logo screen. They gave me a new phone and told me dont f-up this one. Now I'm afraid of updating my phone to the 6.something radio.
Update *Similar Problem (Partial Brick?)*...again.
MasterColdSoul and koolpre,
Thanks for the tips and luck!
I figured it wasn't a total brick so I searched
the whole day on google and xda.
What I can tell you is that I now have a functional phone.
I used the rogers "mandatory" update (2 sappimgs) to
get my phone (rogers 32a) working again (boots fully).
However, I now have the SPL 1.76.0010 which means
I've lost root functionality and it's harder to get root.
But I could use the phone to make a gold card and get root again.
Boy I'm glad this worked! I should have learned my lesson
but I will probably try to root, hehe!
Thanks to google search and xda community!

just because the radio starts with bigger numbers doesn't make it an update. 3.22 was the old radio and 2.33.23.02 is the latest radio so you were actually downgrading your radio and thats why your phone brick. Just letting you know because you seem to be under the wrong impression. Dont make that mistake again. just do a little research to find the latest radio.
Hey everyone.
I was rooting my MyTouch 3g w/3.5mm this morning. I'm following the instructions from here ( http://theunlockr.com/2010/03/11/how-to-root-the-mytouch-1-2-and-fender-mytouch/ ). I had apparently messed up when I was at the restart after flashing sappimg.zip onto the phone and was stuck at the HTC Magic Screen. I restarted my phone by holding down the Reject Call + Volume Down key and told it to flash sappimg.zip onto the phone again so I could redo it correctly. Unfortunately, it's stuck at the "[1] SYSTEM - UNZIPPING" stage. I'm afraid to turn it off because it says to not power off the device.
So, yeah, have I bricked my phone or is there a way to restart this process so I can successfully root?
Thanks much, and have a happy holiday.
EDIT: This sort of resolved itself, but now I can't get into recovery mode. :/

I'm flashing the engineering spl onto there for the first time.
It appears that being stuck at the Magic screen is normal according to a different (but similar) guide from the Cyanogen Wiki. Would it irreparably damage my phone if I removed the battery despite it being at the "Unzipping" screen for Sappimg (as I was unzipping sappimg for a second time) and proceeding with CyanogenMod's guide instead?
EDIT: It appears my phone just turned off on it's own (battery probably died). I'm going to try CyanogenMod's instructions and see if that works.
EDIT 2: So, I reflashed it with the sappimg that Cyanogen has on his wiki. So everything was smooth sailing until I got to the Recovery step. I cannot, for the life of me, to get it to boot in recovery mode. I hold HOME+POWER but nothing pops up.
EDIT 3: And it appears as if I've bricked it.

Will the rom start? If so, you didn't brick it.
Do you have the Engineering SPL on it? What SPL version do you currently have on there? Remember that if you have the T-Mobile US MyTouch w/3.5mm jack then you MUST have 32B recovery and radio and STOCK (1.33.0013) SPL before flashing a custom rom.
Best way to do it is to flash your custom recovery (I suggest Clockwork Recovery for Mytouch/ION devices) by fastboot.
Afterwards then flash your stock (S-ON) SPL back and then boot to recovery to flash your rom.
REMEMBER!!! YOU DO NOT HAVE A 32a DEVICE! DESPITE WHAT THE SPL SAYS... IT'S NOT TECHNICALLY A 32a DEVICE!!! You MUST treat is as a 32b.

Oh, wow. That explains why I bricked the phone. The Amon_RA Recovery I put on there was 32a... I'm an idiot.
The phone won't start up at all. :/ Looks like I'm out $100 or so.
Thanks for that, though. I was going to give you a "Thanks" but it appears the button has disappeared for me.

Any help would be greatly appreciated.
Nice job on probably bricking your phone. You've got the myTouch 1.2 which means you just flashed an incompatible radio. Congratulations!!! I honestly not sure what to tell you. Which sappimg are you trying to use to get the engineering SPL?
Like i said...it was like this when I bought it.
I'm going to try to do a poorman's JTAG...wish me luck.

Good luck! You can do it!
If you have any questions along the way, please don't hesitate to ask.
JTAG did in fact de-brick my MT3G 1.2 (bought from ebay) the first time I tried it. I made the mistake of flashing the stock ROM, so I would get to the "touch the android to begin" screen and couldn't get any further without a data plan. It wasn't until I probably flashed the wrong sappimg in a root attempt that I started experiencing the stuck at unzipping/FAIL-PU/remote signature verify fail problem...
FYI, I tried flashing radio 2.22.28.25 (the one from the OTA) using JTAG and the radata command, and it fixed my USB. I haven't experiemented much beyond that, but I'm planning to try some more things this weekend.
Moderators, I'd like to suggest merging this thread with http://forum.xda-developers.com/showthread.php?t=773368 and http://forum.xda-developers.com/showthread.php?t=771622 since they all seem to be discussing the same problem.
I have a problem with my G1. I've rooted it (with http://forum.xda-developers.com/showthread.php?t=442480 ), and afterwards I had to update SPL (downloaded dangerous SPL from http://code.google.com/p/sapphire-port-dream/downloads/detail?name=spl-signed.zip&can=2&q= ). I've forgotten to update RADIO first, and I am stuck with boot screen.
I cannot use adb, camera+power, recovery (home+power), home+back+power doesn't work either. On boot screen I try to reboot it via send+menu+power, but it doesn't work - the only method is to take out the battery.
Is there any option that I can try to fix it?
I have 1 year more warranty for this phone, so I don't want to lose it.
//I have second G1 working, if that can somehow help in fixing it.
I know it's my fault. But is there anyway I can repair it?
same boat rite now, tried to flash new radio onto my rogers dream last night in order to flash ginger yoshi. after super wiping i then went on to flash the radio and it is now currently stuck at the rogers boot screen not allowing me to enter fastboot or recovery
You cant get into the fastboot? or holding the camera and power?
