Problem Downgrading(URGENT) - G1 General

Hi, sorry about this first topic, but i've been 3 days trying to activate the G1 without Data Sim.
Here is the problem... I got an used T-Mobile G1 3 days ago, it was activate with google account but it was sim locked, so i used it to surf the internet and stuff like that. Navigating the menu i decided to reset all phone data (i didn't know that it get locked again) so, i reset the phone and all data came default and it ask me to activate it again with my google account, but im not in USA so, i have to do it trought Wifi.
The phone have the RC30 and i want to downgrade it to RC29 in order to have the security holes again and be able to activate it trought wifi, but i've tried in several ways and failed in every one.
I've downloaded many DREAIMG but when i turn on the phone with Power + Camera Button i get "No Image File"
Here is the whole text:

I've also tried to run various "update.zip" turning on the phone with Power+Home > ALT+L > ALT+S and heres the result:
E:Can't open /cache/recovery/command
--Install from sdcard...
Finding update package...
Opening update package...
Verifying update package...
E:No signature
E:Verification failed
Installation aborted.
I've formatted the SD Card and tested with different files and still the same. I need some help please, can anyone tell me what i'm supposed to do? or what i'm doing wrong?
Thanks very much.

Is your phone a US phone? Also you said you formatted your card, did you format it to fat32? And did you check the MD5sum on the DREAIMG.nbh file to make sure it's a complete file? And to go to RC29 you do load it thru bootloader (cam and power)

Yes, it is a US phone, i formated my SD card to FAT32, i have downloaded many DREAIMG.nbh and tried to load it trhu bootloader but always get "No Image File"
Also, to make me sure, i tested with a RC7 DREAIMG.nbh and got the same. =(

Um
Are you sure you're extracting the dream.nbh? i member the first time i downgraded i put the zip in there instead of extracting it,

Yes i am, and i've tried with several diferent files

um
Hmm iono weird.

Hi, i have downgraded already, it was a problem with my sd card reader.
Now, the phones reboot when i type <enter>reboot<enter> but when i type <enter>setprop persist.service.adb.enable 1<enter> nothing happens. i'm doing something wrong?
Thanks.

Getting rid of TMobile ROM

I had the XDA special edition ROM on my XDA-I. for some stupid reason i downloaded the TMobile WM2003 ROM from ROMKitchen and ugraded it but i hate it n m trying to get rid of it. Now i have seen in the posts that TMobile ROMs have a problem where they do not let u change the ROMs again using the Program A methods so i m tryin to use the SDCard method, i dont see the screen that allows me to do that when i have the SD card with the image in the slot. Presumably i m doing something wrong while creating the image. I m doing it using XDATools OSImageTool, i have another ROM image NB1 file from ROMKitchen as welll i select that as the source, i select the XDA SD Card slot as the destination and copy over the image. but when i reset with the power button pressed i get the Wallaby color screen and not the flashing screen that i m supposed to see.. Can somebody tell me what i m doing wrong?
thanx
Looks like the rom didn't get wriiten correct on the SD-Card, or you have the wron bootloader version on your device.
Try writing the ROM-Image via an external SD-Writer.
You can also try backing up old ROM to your SD via Bootloader and then look if you're able to reinstall it on your device....
Stefan
stefan thanx for your reply. The bootloader version that shows up when i do a restart with power switch pressed is V5.14, Is that the correct version? Is there anyway to check or insure if the image has been written correctly on the SD card?
I do not have access to an external SD card writer so that option is out the window.

The old ROM i presume is gone? but is there a way? or can i use some other method? I noticed there is this USB flashing thingie if i press the volume button. Any pointers you can give me to use that?
thanx bunches for your help!
Maybe it's a problem of the bootloader. Never had Version 5.14.
You could also try this and then try to reflash your device:
# Download the XDATools ftp://xda:[email protected]/Wallaby/Tools/XDATools.zip and extract them
# Go to a DOS prompt and CD to where you have extracted the XDATools
# Type 'pnewbootloader bootloader_v5_15.nb0' to write the Wallaby 5.15 boot loader to the device.
The output looks like this:
D:\XDAtools\binaries>pnewbootloader_40116 bl515.nb0
Copying D:\XDAtools\binaries\itsutils.dll to WCE:\windows\itsutils.dll
in FindFlashInfoOffset
protection found at 8c0d60f8
result: 00000000 00000000
stefan when i try to do that, the first message that pops up is "Do not run this tool unless; you want to downgrade your 5.17 bootloader to 5.15 you have somehow managed to overwrite... "
Now i do not know if i have 5.17 or no.. as i said i had given you the version from the screen that comes up when u reset while pressing the power switch..
in any case i did a yes.. and it said "Unable to find flash info offset, cannot disable bootloader writeprotect"
thanx bunches!
stefan.. sorry if i m being a pain.. as i mentioned in the last post the bootloader doesnt work.. i think my problem is similar to these guys
http://forum.xda-developers.com/viewtopic.php?t=7646
but i do not have access to an external SD card writer.. so i was looking at this article..
http://forum.xda-developers.com/viewtopic.php?t=2110
i have the mtty utility and i can get to the USB prompt, can i somehow use that to flash the bootloader and the rom? where do i get those files and emm is the method safe?
thanx again for your help
oh btw.. i saw this post..
http://forum.xda-developers.com/viewtopic.php?t=21264
i went over the steps that u had mentioned for making the SD card.. from the device itself..
You require a SD-Card with >= 64 MB
XDAtools ftp://[email protected]/Wallaby/Tools/XDATools.zip
Your downloaded ROM from my kitchen
step1) Boot your XDA up normal and connect via active sync (guest partnership is ok)
step2) Copy all your data of your sd-Card to your local PC otherwise all data on it will be gone
step3) Enter bootloader of your device by pressing On/Off and doing a softreset
step4) After the Message GSM OK press the Contact Button of your device
step5) Navigate with the pad to "CE+BOOT TO SD"
step6) Confirm this with the Action Key (Press the middle of the Navigate-Pad)
step7) After finishing enter again bootloader by holding On/Off and doing a soft reset
step8) Bootloader should tell you something tah OS is detected on your SD-Card
If No -> Problem
If Yes -> continue
i have problems more advice?
thanx bunches!
one thing.. if i take CE+ROM->SD of another device (going a reset with power switched pressed and pressing contacts button), and i put that SD card in my device and boot, i shud get an option to update the ROM from the SD card right?
if i dont.. is there anything that i can do?
thanks
IGA
Same problem. couldn't even boot up using an SD card. I can't even find the wallaby patch
I tried OSImageTool to flash using USB Activesync.
here's what showed up.

same for me, my wildfire is also rooted...
update iso is on sd card, so go to nandroid (boot) and choose zip from sd, then it will update normal
sorry for pure english
Enter in recovery mode, disable signature check under Install zip from sdcard, by pressing toggle signature verification. Next choose zip from sdcard, go to your downloads folder and select OTA_blabla.zip.
I'm no expert but won't downloading OTA updates remove root?
Might be they are settings things up.
P.S. FU HTC, I waited for your OTA very long, and then I rooted. Wish this was 2-4 months earlier. But you have your wealthier customers to focus on, we understand!
Thanks to lazaj007 for general info and to ricardoft for detailed guide,my wildfire finaly congratulated me for updating it .
I have root phone too, i just went to recovery and flash the file from sd card, and reboot it works...sorry for english
I've downloaded update 1.37.405.1. But i can't find any difference. Has somebody found some difference?

it could be long (10-30 mins), depends of your sd card.
Maybe your sd card isn't very good and not compatible with android.
Try to format your sdcard or try another sdcard
Thank you mystikal for everything i switched the sd card, copied the rom and it worked perfectly :beer:
You helped me alot!!!
Sent from my HTC HD Mini using XDA

After oreo screen flashes white and minimised, battery errors

I am on stock 8.0 after the update during a call the phone buzzed and made a loud sound like a siren. After the crash I used it and got message of abnormal restart. I decided to hard reset it. The phone buzzed for about 30 seconds at least and then booted giving me an error uDove to send to HTC. I sent the error and updated all apps to set up.
1. Since then whenever I wake up the phone with the fingerprint or open an app the current window goes white and gets minimised as an app would do. Or as if a pop up goes on and gets closed by an adblock (in desktop).
2. I noticed also lags in performance and battery drain.
All my apps are basic and from play store (major publishers and no games at all) With HTC support I used the phone in Safe mode and no problems where observed. I thought it was htc sense update that was causing the issues however it is not the case. I am lost and do not know what to do. The phone is annoying to use and 4 hard and soft resets did not improve anything.
I ran every check with the HTC utility and nothing significant was reported (all passed ok), During the following hardresets the bootloader gives error

Looks like partitions map is damaged (hard to read the photo). My educated guess is that you either get a RUU from HTC and let the phone recover everything fresh or unlock boot loader and install custom ROM.
Can you use superuser rights via adb in the HTC recovery mode?

HTC is sadly ignoring/abandon the U Ultra. Pity.
NVM
RUU is ROM Update Utility - it is an HTC format for update packages. Sadly, Oreo hasn't been made available by HTC.
Since (presuming) you are still under warranty (no unlocked bootloader etc.) I advise to hit the HTC service center and tell them that their OTA went wrong.
Alternatively I could only think of unlocking the bootloader and doing the fix yourself.
Whitch CID do You have? Is it single sim or dual?
I as an update the phone is getting worse the more I use it. I screen blacks out for few seconds and then back to normal. Something like voltage issues. If anyone knows the UK repair service I would appreciate the details. They are not responding e-mails and chat is not helpful at all.
It is bought with UK plug so I assume it is the ones in UK?

So. You have nothing to lose. Try to copy OTA to SD card. Clear Cache and Apply update from SD Card. Maybe it Will help...

Edit:
Or downgrade to Nougat, then try with OTA again.
Hello everyone, after buying a new device (huawei) and after 4 visits to the repair center my phone seems to be replaced with another one. unfortunately the battery was changed and it is worse than ever (after a hard reset it says it was last fully charged 223days ago.
I solved the problem by doing a hard reset and not updating the google app. My last reported version (installed by HTC) is 7.17.28.21.arm64 (my device is HTC U ULTRA but same problem). After this everything else runs smoothly etc.
I believe it relates to new features of the app that change completely how it manages the device
• Use voice commands while navigating – even when your device has no connection. Try saying "cancel my navigation" "what's my ETA?" or "what's my next turn?"
• Weak connection? If your search fails, the Google app will deliver you results once you regain connection.
• Troubleshoot connectivity issues with more helpful error cards when your search fails because your device is offline
• New customization options available for cards in your feed

Chinese Android Radio XYAuto 8227L YT9213A Firmware Update(help me please)

Hello all,
I am not a professional but still ambitious and would like to solve the existing problem
Since my English is not perfect, I use a translator, sorry if some written is not understandable.
Coming to my problem.
I bought 2 years ago from Aliexpress from a reputable seller an Android. 8227L YT9213A
From the beginning, the device was very slow or lost the GPS data.
original firmware was YT9213A_00009_V001_20200408
{

"lightbox_download": "Download",
"lightbox_share": "Share",
"lightbox_zoom": "Zoom",
"lightbox_new_window": "New window",
"lightbox_toggle_sidebar": "Toggle sidebar"
}
before the failed firmware update
As a result, the seller sent me a firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200517". I copied it to a USB stick (rar file not unzipped) and successfully performed an update via the radio menu "Android Update".
Over time, however, I noticed that the navigation "google maps " always crashed. also lost the gps data.
about the playstore to update the apps brought no success. the problem was in my opinion on the android system,
it was still slow and not fun at all.
I have now contacted the seller again and informed him about the problem.
he sent me a new firmware "gongban_YT9213A_ui1-hw-ota-v6.5.zip".
after some research i found the XY Auto firmware download page.
XYAUTO
file manager
file.xygala.com
there I found exactly the same firmware what the seller sent me.
I copied the firmware zip file to a USB stick and tried again to update the firmware via the radio menu "Android Update".
Unfortunately, an error occurred, I have repeated the process several times. tried different USB sticks but it always came to the same error.
I think that this firmware what the seller is not compatible with my device at all.
I have on the http://file.xygala.com site then a previous firmware and that is
"xyauto_ui1_9213A_full_8227L_demo-ota-20200523.zip" downloaded and copied the USB stick and again through the device menu" Android update" performed.
This time I noticed that it did not come to an update abort. it came the message 1 of 53 apps are updated, but at "23 of 53" it froze and the system was rebooted, then the installation continued "1 of 9 apps" are updated. Finally the message came, "Update complete".
then the system was rebooted but the startup screen froze, the touch did not work. the image distorted and after a few seconds the system was rebooted again. this phenomenon repeated itself again and again. so to say "boot loop effect"?
then i started to research on youtube saw some videos how the firmware was updated with flashtool. i wanted to copy it. I downloaded the "Scatter-loading file" from the firmware folder the seller sent me "gongban_YT9213A_ui1-hw-ota-v6.5.zip" ( but I downloaded the same firmware for PC update from the http://file.xygala.com site
downloaded) and loaded and thus tried to flash. the " preloader " in the first row was not activated. the hook was missing. manually I could not click either.
Then I tried to load the "scatter-loading file" from the previous firmware "xyauto_ui1_9213A_full_8227L_demo-ota-20200523" and flashed " Format All+ Download" it started to load at the bottom of the bar but then came an error message.
So now I think I have made things worse.
Now the screen stays completely black. Android loading process I do not see. I see short flickering but it remains black
The seller only answers when he feels like it and doesn't really help me.
It would be a shame to throw it away. I don't think it's a hardware problem.
Can anyone really help me from afar and give me a tip.
I would follow any instructions and try to revive the device.
thanks in advance and hope someone will help me.
Do you have a 'Preloader' file?
Dont do formatting without 'preloader' file.
You can only do a downloading without this file. I dont know why flashtool even let you do this step without all files included....
Im using this version: sp-flash-tool-v5-2112
Then get the 'preloader file and use with package 'xyauto_ui1_9213A_full_8227L_demo-ota-20200523' you've got. Do format wit all files included/selected.
hello guys i have this head unit and i really want to change the firmware .interface ugly and aux deosnt work no sound equilizer ....
any suggestions plz
hello, i have a chinese car radio ff-5000 8227L, i installed avg anti-virus, then i activated the screen lock via this antivirus, please how can i deactivate the screen lock ? THANKS
