I9020a Unable to Flash - Nexus S General

I'm having problem flash this phone with any ROMs. Every ROMs that I have tried resulting
E: failed to verify whole file signature
E: signature verification failed
Installation aborted.
Model number: Full android on Crespo
Android version: 2.4
Baseband version: I9020AUCKA6
Kernel version: 2.6.35.7
Build number: full_crespo-eng2.4 Gingerbread 101 test-keys
Also I cannot get windows 7 to see this phone. I have installed the USB driver via SDK manager and I also add these lines to android_winusb.
;Google NexusS
%SingleAdbInterface% = USB_Install, USB\VID_18D1&PID_4E20
%CompositeAdbInterface% = USB_Install, USB\VID_18D1&PID_4E20&MI_01
When I boot it to stock bootloader below the android animation are two lines:
USB Control Init
USB Control Init End
Can anyone help? I would like to restore it. Currently I can only use text and voice. Thank you.

You need to unlock your bootloader and use a customized recovery like Clockwork recovery.
PS. there is no android 2.4

When I boot up by holding vol+ and power button I am in fastboot mode and lock state is unlocked. But at this point Windows 7 does not see the phone at all. Under device manager it lists Android 1.0. Where can I download the driver for it? If I can get Windows 7 to see it then I can used Odin 1.85 to recover it.

Also this phone was given to a friend that work for Samsung.

Go through all of part 1 from the rooting guide, you seem to have gotten about half-way there.

From the bootloader you can flash the original firmware again and get your phone back to life.
Get your firmware from here: http://sbf.droid-developers.org/umts_milestone2/list.php
Keep in mind that you need to have a fully charged battery before flashing, and you can only flash a firmware that is the same version or newer that the original in the phone (newer is always better)

Same problem for me: would appreciate help
Hello !
It seems like I am having the same problem as lukasz0318, but I don't know how to solve it, even based on what has been said before. That's why I am posting here.
To summarize it : I am not able to boot into Recovery Mode anymore on my Milestone 2, so my phone is soft-bricked. I am able to boot into Bootloader Mode.
I already posted my problem on the Android StackExchange (android.stackexchange.com/questions/27553/how-do-i-enter-recovery-mode-on-my-motorola-droid-2-global-to-unbrick-it), but as I have had no answer there in 8 days, I suppose XDA-Developers will be a more appropriate forum. Anyway, let me recap the problem. Hold on, since it is quite an explanation. You may jump to the last paragraph.
I own a Motorola Droid 2 Global, also called Milestone 2. It used to have Android 2.3 with Motoblur middleware. I don't know what firmware version it had, but it was updated earlier this year by the manufacturer. I bought my phone in France independently from any phone carrier (so it was not bought from Verizon for instance). I rooted it, installed ROM Manager, Droid 2 Global Recovery Bootstrap and ClockworkMode Recovery. From ROM Manager, I could successfully reboot my phone into Recovery mode, allowing me to back-up my data for instance. Until this stage everything went fine.
What lead to my problem : I also wiped the cache and installed CyanogenMod 7.2 and the Google apps from ZIP files and from the Recovery Mode interface. But now my phone is broken. When it now boots, it shows the stylised M logo, but then switches to an entire black screen. The phone is still on so I have to pull the battery to shut it down.
I would like to reboot into Recovery Mode but this doesn't work : I am never able to see the Recovery Mode logo (a warning sign with a little android). How should I do it ?
What I have tried : I tried to boot while holding the Power and the 'X' button, as adviced on different forums. This still leads to the black screen. At this state, pressing the Search hardware button does nothing. Holding the Power and the Volume Up button has no more effect. I am able to enter Bootloader Mode by holding Power and Up Arrow. Procedure suggested by Verizon
I also tried to use a Slitaz live CD with ezSBF on it, that I*downloaded from www droidforums net/forum/droid-2-global-hacks/170060-tool-ezsbf-d2g.html#post1726853. But I get errors in the process and then my phone reboots in Bootloader mode and shows the following error:
Code:
Critical Error:
FEBE 0047
After that I still cannot get to Recovery Mode.
I also took a look at Caesarivs' link (sbf.droid-developers.org/umts_milestone2/list.php) but I don't know which SBF to pick and I don't understand lukasz0318's answer to it. Which is a pity since the link was successful to him.
Could you please give me some details on the procedure to follow ? Additionaly, could you post me a link to your favorite and up-to-date tutorial on how to restore the Recovery Mode ?
Thank you very much !
1) A Milestone 2 is not the same as the D2G. If you bought your phone in france, its a Milestone 2.
2) You flashed the ZIPs on moto's recovery, not ClockworkMod recovery.
Try this:
1) Flash this SBF: http://sbf.droid-developers.org/umt...MILE2GBRTFR_P012_A006_HWp2a_Service1FF.sbf.gz You can flash it with RSDLite on windows or sbf_flash in linux.
2) Root it with Doomlord's one click root.
3) Download droid2bootstrap (NOT the global one) bootstrap recovery, and flash bootmenu (attached to this post)
4)Reboot once normally, reboot again, and press the volume down key when the LED flashes blue.
5) Flash CM7.2, the google apps, wipe data/factory reset.
6) Fix baseband (if you have problems with 3G or signal) with Milestone2 Baseband switcher v2: http://forum.xda-developers.com/showpost.php?p=29580375&postcount=696
Hope it helps you :good:

Thank you very much, Lean946. I didn't know there was a difference between Milestone 2 and Droid 2 Global. My mistake.
As I use Ubuntu 12.04, I tried to use sbf_flash but this brought up an error:

In progress…
It has been so for several minutes. I'll wait a little longer and if there is positive evolution I will edit my post.
Anyway, is this the expected behavior*?
I'd try waiting a few more minutes, if sbf_flash is still frozen, try unplugging and pulling the battery out and trying again, if it still won't work i'd take it to a windows pc, I never had any issues flashing with RSD, and I tried Milestones, Milestone 2s and Defy's.
Good luck.

Thank you very much ! I found a Microsoft Windows machine, found a download of RSD Lite (which was not very easy) and finally installed the SBF you pointed at. It worked very well to unbrick my phone ! It is now back to Motorola's ROM.
I will now try your following points in order to install CyanogenMod. Whether everything works fine or not, I will post an update.

I think I did exactly what was indicated here: step 1 to successfully unbrick the phone, then step 2 to 4.
Step 4 lead me to an interface called "Android Bootmenu" (different from the Bootloader Mode). From there I could not flash any ZIP, but I could launch the Custom Recovery. In my case, ClockworkMod Recovery. From there I wiped data/factory reset, then I flashed CM7.2 and the Google Apps, and rebooted.
But now my phone doesn't boot properly anymore. The stylized M logo keeps appearing and disappearing. As the LED regularly becomes blue, I can enter the Android Bootmenu, and then the two Recoveries (ClockworkMod Recovery and Android Stock Recovery).
What should I do now to finish the install of CM7.2 ?
Might the reason be that I installed the wrong ROM (or the wrong Gapps) ?
I tried the following ROMS :
cm-7.2.0-droid2we.zip from get.cm/?device=droid2we&type=stable
cm-7.2.0-umts_sholes.zip from github.com/nadlabak/android/downloads
The first one gave me no error output during its installation in ClockworkMod Recovery.
The second one gave me an error :
Code:
E:Error in /sdcard/update.zip - (Status 7)
.
Do you have any suggestion or a link to your favorite tutorial ?
Finally, the following ROM did work, with the same procedure as I used to do :
CM9-NIGHTLY-120815-milestone2-eu.zip from forum.xda-developers.com/showthread.php?t=1623385
I ran into another final small problem (I could not close the Setup Wizard), but that was easily solved with the "Four corners method".
Thank you for your help and wish me good luck on my new operating system !

Your bootloader is locked. No possibility of flashing TWRP or any other recovery, kernel or ROM other than what's already on your phone...
The only thing you can do is root which you have already done. Next step is debloat and learn to live with your phone

Problem Installing Bootloader and Recovery (AfterOTA)

I want install a custom Rom like cm or other stable recent. So, beeing a newbie, I decided to use afterota to installing BL e CR. I have A500:
Android Build : Acer_AV041_A500_1.031.00_WW_GEN1
Bootloader : 0.03.12-ICS
I tryed to install all option in Afterota Standard TAb, installation succesfull, but when I try to boot tablet after attemps I have this result: or boot normally, or with this: some strings in the bottom left and i0t briefly shows the Android and then android with the red exclamation mark in the triangle.
- Any help to use this tool?
- And, any help/guide step by step to install this elements also manually? (I thing the process is: unlocked bootloader, custom recovery, rom....but I dont know how)

I think I brinked my phone. Please help [SOLVED!]

Hello. I tried downgrading from the latest ASUS firmware to Android 6.0.1
I used this tutorial to install the raw firmware: http://www.asus-zenfone.com/2016/12/asus-zenfone-3-raw-firmware-and-asus.html
Went all the way to the last step when the app hanged. ASUS Flash tool went all the way saying
Code:
Run flash image script ...
It was hanged there. And as per this video, went all the way to the end where it showed the "code bar" on the right (https://www.youtube.com/watch?v=P8xg7A-P7Ak)
This is when the "Android" uninstalled driver showed up in Windows. This is under "Other devices - Android". I tried updating this driver using the ASUS_Android_USB_drivers_for_Windows found here: https://www.asus.com/Phone/ZenFone-3-ZE552KL/HelpDesk_Download/ but it wouldn't install the drivers.
Note that I used these ASUS USB drivers to get the ASUS ADB Interface installed. As per the tutorial I showed in the very first paragraph, I never got the "ASUS Android Bootloader Interface". This is what I think this "Other devices - Android" is found under Computer - Manager - Device Manager.
Most tutorials on the internet shows that the "ASUS Android Bootloader Interface" should be installed using these drivers found on ASUS website, the ASUS_Android_USB_drivers_for_Windows.
Now of course because I unplugged the phone, it will continously stay on the Android splashpage showing the loading circle infinitely.
As a last attempt I tried installing the "stock", not "raw" firmware (the one I wanted to install WW_13.16.5.49 but ASUS would not let you downgrade using the recovery "power+volume down" and using "Apply update from microSD card". It would give the
Code:
Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.
)
Well, after it brinked, I tried it again and this time it DID install WW_V13.16.5.49. Was succesfull. But after the ASUS splashscreen it's still stuck in the booting process.
I am very sorry if my post is convoluted but I tried explaining everything I did. Any way to un-brink it? I think maybe if I figure out how to properly install the ASUS Android Bootloader Interface, I can try again ASUS Flash tool and install the raw image and maybe that will fix it?
Please help. Any questions if my thread is too confusing, please let me know and I will answer it. I can't even turn off the phone. While it's stuck into the load splash screen, if I press the power button it just restarts, not turn off.
I still have access to fastboot (pwr + volume up) or recovery (pwr + volume down)
EDIT: Phone won't get recognized anymore in ASUS Flash Tools. Serial number won't show up to select
Factory reset and delete cache/dalvik through recovery and post back. It'll take 5-10min to boot up after that. You should always delete cache/dalvik after flashing.

Thank you, this actually worked!!
Aaaand, it's actually on the version 13.16.5.49!!!! THIS IS EXACTLY WHAT I WANTED!
So apparently by brinking my latest nougat 7.0 update from ASUS via the ASUS Flash Tool trying to flash the .RAW 13.20.10.137, the standard recovery system (power+volume down) allowed me to install the 13.16.5.49 version. Then I assume remnants files didn't allow to properly boot, and your idea to wipe cache and factory reset fixed that!
What is so great is that I was scared that because the .RAW firmware was newer than the version I needed (13.16.5.49), I wouldn't have been able to install it. It was the same problem initially, when I tried to install 13.16.5.49 directly via recovery over the latest nougat 7.0 version from ASUS, but it was giving me
Code:
Warning- No file-contexts. This package is for "ww-phone" devices, this is a E:error in /side load/ package.zip (status 7) Installation aborted.
I think this error was due to the fact that ASUS won't allow older firmwares to be installed over newer ones, as per their webpage
https://www.asus.com/support/faq/1009748
Code:
You can not change the SKU from one to another, e.g., WW -> TW, and also can not downgrade your firmware, e.g., V2.20.40.13 -> V2.19.40.18
So in the end, what allowed the 13.16.5.49 stock firmware to be succesfully installed? The installer not detecting a proper firmware anymore because of the damaged update due to ASUS Flash Tools hanging because my computer won't install ASUS Android Bootloader Interface?
Glad you got it going :good:

/e/ OS (8.1.0) Bullhead - Oreo dev (beta) -Degoogled ROM

Posting this link as I couldn't find a link to this Project anywhere else.
The main page is here https://doc.e.foundation/
and the Bullhead download information and links are here
https://doc.e.foundation/devices/bullhead/install
Unfortunately it is now classed as a legacy device so no longer receives updates.
However that wouldn't stop a developer from doing an unofficial build etc. I was thinking of it in order to update
it to Android 10 or 11, but you apparently need 16GB RAM and 400GB free space to install 'Docker' on a Linux system,
which I don't have at the moment.
An interesting Project though.
The installation runs completely through, but then booting stops at the "Google" sign.
Next try: Install a stock android (using Nexus Root Toolkit), then install the recovery anew, boot recovery, format Data, Cache and Dalvik, and install /e/ OS as described.
This time the e with the bouncing dot appears and then I get to read
Android System: A vendor image mismatch has been detected. Typically this means your vendor image is out of date. Please ensure your vendor image matches. OPM7.181205.001
Click to expand...
Click to collapse
And when I touch the "OK", "System UI has stopped". Any idea how to fix this?
Followed THIS instruction. The same error...
Do you have the latest (ie last) Factory Image? In fastboot mode you should have Bootloader version BHZ32c and Baseband M8994F-2.6.42.5.03. These should correspond to the factory image 8.1.0 (OPM7.181205.001, Dec 2018) which you can download at https://developers.google.com/android/image.
You need to have this factory image installed before installing TWRP and then e/OS.
Once you get into e/OS you might find an error message about eSpeak TTS when you click on camera or Maps. You can resolve this by going to Settings-System-Language&Input-Advanced-Text to Speech output and changing it to 'Pico TTS'.
You might find this list useful. Had to convert it to a .txt file as I couldn't upload spreadsheet file.
FYI, I installed Ubuntu and Docker on a spare hard drive and followed the e /OS instructions to try and build an Android Pie version for bullhead, but the process failed. Meantime trying to read the log to see why it failed.
OK, next try: I managed to install the stock rom that you mentioned. The bootloader version is now BHZ32c and the baseband is M8994F-2.6.42.5.03. The download link changed to https://developers.google.com/android/ota?hl=de#bullhead from which I downloaded the latest OTA version 8.1.0 (OPM7.181205.001 from December 2018. And after 32 bounces of the dot it booted! Now I have something to play with again.
Thank you!
That is great. That should be your de facto Stock ROM to flash everytime you need to restore your phone. The other thing to note/check next time is in the stock Android Recovery screen (before you install TWRP). It should say at the top google/bullhead/bullhead and then 8.1.0/OPM7.181205.001/xxxxxxx. This again confirms the version you have installed in your phone.
If you are not sure how to get into stock Android Recovery, first boot into Fastboot Mode.
Use Vol up and Vol Down to scroll through menu and the Power button to select an option:
Start
Restart bootloader
Recovery Mode
Power Off
Select Recovery Mode then wait until you see the 'Robot lying down' and "No command" text appear on screen. Now hold Power button and briefly press the Vol-up button.
Android Recovery screen should now appear.
