**SOLVED**Help! secure boot: image SOS checksum fail! the sequel..

Hi guys i know Brian117 originally posted this and sc2k helped him fix hes tablet i apologize for not continuing the thread
but its been almost 8 hours since i bricked my tablet. i can't take it anymore i tried alot of things i search Google for answers until i gave up.
Im not a pro but im not new to flashing roms so i originally installed CWM from the "it's Magic" post from sc2k i did it successfully then installed
Dexter's primee rom successfully aswell no problem. Once i discover Virtous picasso rom, Honey Villain rom i decided to test them out aswell
see witch one fit my liking so i did successfully. After seeing Virtous galaxy i decided to check it out i did i got an error at boot so after posting
my error some suggested i update my CWM so i was able to boot into galaxy rom loved it then i downloaded "update-recovery-thor2002ro-rev1.3.4"
from the instruction i gathered im suppose to just flash it through CWM so i did and it said that i succesfully flashed it now reboot into CWM to see
the changes so at this point i thought heck yeah!! then to my surprise i reboot it the tablet and was greeted to " secure boot: image SOS checksum fail!" so i then tried a normal reboot the ACER logo just stood there hanging looking back at me laughing.
Before i originally installed CWM i followed all instruction so i have all my back ups and UID saved on my PC. i Already pm sc2k about see if he can help me
but i thought i post the whole processed of what i did to avoid others bricking their tablet aswell and hopefully in the mean time if any of you guys have any suggestions, tips i gladly welcome them since i cant return it to staples anymore i have to deal with Acer if i cant get it to work. Also I fully understand this is a risk i took and not blaming no one for my error all im asking is for help

u done one wrong step, u didnt run its magic before installing thor recovery i think..

I am pretty sure that thor explains in his thread that you should flash his "update-recovery-thor2002ro-rev1.*.*" files only if you allready have his version of recovery installed.
So you should have installed the full "recovery-thor2002ro-rev1.3.4.rar" as described in 1st post of his thread and not just try to flash the update-recovery file.
Maybe thor or sc2k can help you now..

I think the problem was that your original cwm was an older version that did not run itsmagic automatically on startup and the update package doesn't run it either. I'm so glad to see someone who has backups!
Don't know if this will help.. The hang at the logo is usually an indication of needing to do a data wipe after installing a custom rom. Was the tablet booting normally before flashing the cwm update?
Anyway, this thread from sc2k demonstrates a method to wipe data. You can see if that will help get you past the logo screen. If it does, great.. run itsmagic, then you should be able to get back into recovery.
If it doesn't help, you'll need to ask sc2k how to unbrick via nvflash (that's what mcblk0_start file is for).
Edit: aw man..I just realized I forgot the link.... ah well

Update: with help from sc2k i was able to fix my tablet it worked great.
and im currently installing a custom rom through Thor2002ro CWM.
Thousand thank you's to sc2k and everyone in the Development comunity
for the advice i knew if you guys couldnt help me no one could.
thank god for the XDA forums.

How do I PM SC2K. I have the same issue with my a500. LNX Checksum error. I Need Help!!! Please Help.

Need some help restoring - Not A Normal Issue Here!!!

Ok, so I have a Droid X2, and the Droid X and Droid 1 as predecessors. I have never had any major problems, and the few that I couldn't get around I had SBF via RSD for. To my knowledge, there is no form of SBF for the Acer A500 (yet). So heres the issue:
I may have either flashed an update without the proper files to go before it; or I have have forgotton to wipe something. Nonetheless, my A500 wouldn't boot. When I did some research, I went to this site:
{http://forum.ppcgeeks.com/showthread.php?p=2127076#post2127076}
because it seemed in my eyes to have the most pertinent information. I got the update.zip to install and my A500 booted again! However, I could not get to stop two because my insternal SD card was wiped somehow and when I get to the main screen, do the circular unlock, the launcer, and many other programs repeatedly force close, so much so that I cannot do ANYTHING. How would you approach this, and is there a way for me to get into CWM. I have a recent nandroid backup that what 100% functional, and I would hope the MD5 sums would still match....
Any help/advice is greatly appreciated!

The top link provides a way to install via Acer recovery the new 3.1 OS, but to my understanding its unrootable for now, is that still the case?

the update zip is uploadable even without root.
just like the original OTA firmware. Try it, many other users got back their pads with this one, as you can see in internal posts of the thread

I totally get what you're saying. What I meant is that if I did the update, it completed successfully, that I would then NOT be able to root the device. Obviously that is a better option that a brick! But I'm trying to find out if I can recover to the most updated version that has been rooted.
Maybe I'm wrong and a root program has been made for 3.1?

hey mate, U quite a little lazy readinf threads titles uh...
take a look at this http://forum.xda-developers.com/showthread.php?t=1138228
pick up the 1.3 version. it will root your "definitely final" version of os, this update U have just uploaded IS the last one available, and it's eligible of any further OTA update...
take care

I work 70+ hours a week, I'm certainly not lazy. But that is why I ask these questions hoping for someone to give me a little short cut to the answer. Between work and sleep I have 2.75 free hours a day and do NOT want to spend them reading a forum where its a lot of bs banter in between the actual info. I'm sure there are a lot of people out there that just don't read, but I truly don't have the time.
Also, this is one of the biggest forums for Android out there. Theres no way I could ever read the HUNDREDS of threads just on this device alone....
I do appreaciate your help!!!
I'll give a final report when I have a chance to do it!

This method did NOT work. When I boot into recovery, it always goes to the screen with the triangle and the android. I never see a progress bar....does this matter?
I also tried your other suggestion of "wipe device without recovery" and that didnt work as well.
I know its not a lost cause since it boots all the way up. But every app force closes so I have NO access

YOU have to do things in proper steps !!! ( lack of sleep will do that to you ! )
1/ grab the file from that thread
http://forum.xda-developers.com/showthread.php?t=1159443
( remember to unzip it to get update.zip file and placed on your card and flash using normal recovery.... not renaming ! )... assuming you don't have CWM at the moment.
2/ grab the "iconiaroot 1.3" file to root your device ( as CWM and Acer Recovery Installer required root access )
3/ grab the Acer Recovery Installer and proceed to install CWM to your device...
after all those are done... work your way with CWM ( to access CWM ... you need to keep holding the buttons (Power & Volume down) until you see 4 lines of text...and not let go before that !! )
remember to wipe cache & factory reset ( both before and after to ensure 110% cleaned to avoid errors and FC )
good luck !!

So I responded to this last night, but somehow it disappeared?? Anyways, thank you for your effort to help me resolve this, but if you look at my initial post, there's no way your description and process would work. First of all, the update above I tried (like I mentioned) and it did NOT work. Also from my description I mentioned that when the tablet does boot, it boots to the home screen (stock green) but, all the important applications, the launcer included, force close so rapidly and repeatedly that I can't do ANYTHING. Thus, I would obviously NOT be able to install any programs, let alone root the device.
Thus the name of this thread....

And obviously you are suffering from lack of sleep !!
The update.zip ( after extraction ) from that thread can be flash either normal recovery or CWM recovery.
and here's the added tool to wipe without a recovery:http://forum.xda-developers.com/showthread.php?t=1132760
Therefore... what's stopping you ??
and please re-read my steps above.. after flashing... you will need to root and re-flash CWM using ( Acer Recovery Installer)
maybe you're not clearly looking at the picture...
there are 2 recoveries ( normal Acer stock recovery and CWM recovery )... DO NOT mistake Acer's stock recovery for the program called Acer Recovery Installer.
what Acer recovery Installer does is install CWM recovery for you and also backup/restore your original Acer recovery.
and you cannot use the program until you are rooted ( step #2 above )
FYI ... each recovery boot differently !!
Stock recovery -->> hold Power & volume down ( closest to the power button ) until some text appear 2-3 lines )
CWM recovery invoke differently.... ( hold Power & Volume down until you get 4 lines of text... do not let go anytime earlier then that )
~~~
extract that update.zip file ( my guess is this is where you went wrong... you didn't extract ? )
when you extract... make sure only the update.zip is put on your MicroSD card ( format FAT32 ).... no sub-folder...etc
Then insert into device and use the stock recovery method above.
if all else fail... get a different microSD card !!
then follow steps #2 and #3 from my previous post .
again... what's stopping you ??

I did the steps that E.B. recommended initially (directions followed religiously). Then I did what you posted (twice now,again, religiously - and yes I know how to, and properly extracted the update. !). Furthermore, I also tried a totally different SD card. 8gb pny VS 16gb San disk.

[Q] Xoom files doesnt change

Hello guys,
i got a serious and frustrating problem here.
A few days ago my xoom was stuck on the M screen, so I used a thread in the forum and recovered it.
It solved myh problem back then, but since I had 3.2 before this and the solution injected me with Android 3.01 my problems started to show themselves.
the first one is that
<b> Through Fastboot, RecoveryMod, ADB </b> and any other way you can Imagine to install a new ROM or even remove or create a file,
All of them show success message but when I check them out I see no changes.
i tried fastboot and Recovery to install nearly every ROM,Recovery and bootimage in this site but so far it was wild goose chase.
so I want to ask if I'm doing anything wrong or if you need any more information here, but please help me with this

wow I cant believe it, All these masterminds here and no answer to my distress signal??
Guys I am so in trouble and this is the only place I hoped to get answered.
I can provide you with more info if you need, but please dont say I'm on my own here.
all these years this forum was the last hope for me.
i know I'll get my answer here one day

You are not being very clear about what you have done,, but I'm assuming that you reinstalled the stock image that got you back to HC 3.01. Can you see if you are able to get OTA updates to get you back to at least 3.1, or 3.2 if possible?

If that's my problem forgive me please, Ive written that post in 3:00AM
for the sake of clearity I should add some info:
1. I even tried stock ROMs but you see I cant even flash them (Not from Recovery nor Fastboot) the steps seem successful : it opens the package,it installs them and it says everything was a success. But when I restart the device I see nothing has changed.
2. OTA updates are the same, they keep downloading and when the sysem reboots to recovery to install them it cant find them.
3. You dont believe it if I say even files and programs that I remove from device by my hand(Android OS) are back after the first restart.
And you see it's dark magic! everything from a file to a partition are back by one reboot. I dont know what should I call it but I havent seen anything like it on the whole Internet.
So seems like I should make a competition for the xda experts here
Can you publish it so all of them can see it?

Actually, I have seen someone with the same problem here on this forum, but I can't recall exactly what the solution was.
Can you describe, step by step what you are doing, what cable you are connecting to your pc with, etc?

That would be relief to know this could be solvable.
I will look more too.
As for your post I must say:
1. I plug the Xoom to the PC using the included cable
2. I start the xoom and start fastboot
3. on the PC system has the drivers and completely knows it
4. I start with SDK:
I. Fastboot oem unlock (Completing onscreen instructions and reboot device)
II. Fastboot mode again I use Fastboot flash boot boot.img
III. Continuing with Recovery,System
IV. Rebooting the device anything is the same.
My ROM is unchanged by the process and keeeeeeeeps giving the damn error of System process error please submit
5. And with ClockworkrecoveryMod I have the stock ROM on my sd card.
I. I choose install zip from sd card.
II.Choose the correct zip file and start flashing.
III. Choosing Wipe Data/Factory reset will take the device into a complete hang. unless I first use the mount page to mount the System/Data
IV. I reboot the device and ..... you know nothing changed.
so thats my story.
Still hope to find something about it.

Thanks...that was helpful. But now I want to know the following:
Were you rooted before the trouble started?
What did you do to recover?
If rooted, what version of CWM recovery did you have installed? Did you do a nanadroid backup? (I guess the answer is no, because you could have just restored with that).
What recovery are you accessing when trying to flash a zip file?
If you can answer these questions I will continue to wrack my brain trying to recall where I saw that thread.
Edit: please check out this thread http://forum.xda-developers.com/showthread.php?t=1370312
Some of what I said to him may help you .

Being rooted? -> Yes, The world is more beautiful with root!
to recover -> I followed this: http://forum.xda-developers.com/showthread.php?t=1097997 Shame it was Android 3.0

And for your help I must say you are definitely the most caring person I know...
I'm off to check the provided link now

I was thinking of something that might be a reason.
I have this tiny problem:

I was thinking of may be the userdata partition is corrupted and I gotta find a way to flash it completely.
Somehow I used Fastboot utility to do this and after saying Success, Nothing changed again.
Do you know any other way to physically do this job?

[Q] iconia bricked - need help

thanks to everybody, as i described in another post i bricker my iconia trying to downgrade from ics to 3.
i've read a couple of posts, i've found tolls than could give me achance to recover but i don't know my serial number.
so first question i ask is: opening a ticket with acer assistance they show as serial number this:
XEH6LEN0021140E7131500
i tried to take apart the last 15 characters and add a 0 but no luck.
is there any other solution ? is there a chance to get somewhere an update.zip signed ?
sorry if i asked stupid questions but i'm a noob and quite desperate.
i know i did something stupoid and i won't get upset if someone reminds me this ....
thanks to anyone that reads, cheers and sorry for bad english

no that's not it
r u back at hc or still trying to get back
check the guide in my sig to get yr cpuid. haven't failed 2 find one yet

many thanks.
i readed your guide before bricking, i tried looking in pc system (but i had only an eleven digit number) and i tried with a terminal app on the tablet, but it didn't like one command.
now that is bricked i don't know how to get it.

Things are looking grim if we cant get your cpuid
I take it you don't have a backup with the uid.txt file somwhere on your computer maybe????
The 11 digit number is a small hope as it suggests you're on the HC Bootloader in which case yes you are able to recover using an update.zip
go to this link and follow METHOD 2
the update zip you have to d/l is UNSTABLE and tricky to use
but all you need it for is to ROOT (with Iconia Root from the market),
and install CWM (with ACER Recovery Installer also from the market.)
Once you have CWM make a backup and get your uid from the text file in the backup folder -
make a copy of it AND KEEP IT SOMEWHERE SAFE!!!!
if you have problems booting the UNSTABLE rom you have to do a hard reset (see below)
You may also need a rom to flash seeing you dont have a backup to restore
you can give hard reset method a try on your bricked tab first- dont think it will work - but u never know.
1) Turn off your tablet,
2) Have the Rotation lock on your left;
3) Press Vol+ (which is next to rotation lock) and power on simultaneously
4) As soon as the tablet vibrates you can release the power button and
you should start to switch rotation lock left and right till you see
Erasing Userdata...
Erasing Cache...
Vol+ is still pressed;
5) The tablet starts to format
6) Your tablet will be as clean as it can be.
Good Luck

many many thanks for your help, i don't know how to thank you enough.
i tried the hard reset, but i still get the boot verified failed ...
the update.zip file in method 2 is the one i used to brick the tablet.
i tried again, the message i get after the flash is:
Not legal !!!!!!! abort
Warning: The blob package is not official ~ Abort!
followed by the red Boot verified failed.
maybe i could try another one, but i don't know where to get it.
i tried to read how to extract one from an entire rom but it's a bit tricky and my antivirus reports the tool as a trojan.
i'll try to look around, then i think i have to send to assistance.
thank again !

could you please tell me what to do ? i downloaded the file root3.2.1 from timmydean but i don't know what file to use, since it's not a zip file but there are many files and folders in it.

timmydeans should be a zip not sure where u got it
ive attached a pic of the folders in my timmydeans v4 should be similar,
theres a readme and pdf in there with all the instructions but basically
1. run test.cmd just click on it - you have yr tab connected to the pc
2. the window should say list of devices attached followed by yr CPUID
You HAVE to get this to show up the rest of the process wont work otherwise.

just my input... might be wrong, but every tidbit helps.
In USB Deview, I believe you look for android.bootserial if it's the same as we run dmesg from ADB, Not sure but check it. Never ran USB Deview before.
Also, one of my russian colleagues said that everytime you connect the USB to the PC, windows keeps a record in the Windows/temp folder for the device ID. If I can find the PM in my mail, I'll post his info again. Theory is, you may be able to get it from temp, so don't clean your temp folder.

ok, under serial number column there is only the 11 digits, so no way.
i'll do some trys using zip files of official roms and trying to get an update.zip working, if i don't get results (as it'll probably happen) i'll give up and send it to acer assistance.
you were very very kind, thanks.

are you taking on the next shift moscow?????
what do u think if he cant get his ID and an update.zip wont work??

Yeah, you're close to being fubarred if you don't have a UID and running ICS Bootloader (hacked version). But not totally.
INFO: I couldn't find the PM from my russian friend explaining how he found his in the Windows/temp folder, as some strange named temp file. Mainly because it was through ATG site, which is no longer there anymore.

Yeah, looking at your image, it seems to show your current UID under ICS. This is both good and bad.
Good, because you should be able to go to Civato's Bootloader thread, and convert it to SBK, then NVFlash a new ICS bootloader and recovery. Then install an ICS rom.
Bad, because that number will not work with a HC EUU, or even running the update.zip from the SD Card.
In theory, the SBK generated is the same for both HC and ICS UID. At least in my case. One would think Vach could reverse the process to generate a HC UID from the SBK. In theory.

Yeah, flashing bootloader the manual way can be a bit confusing. It involves setting your tab to APX mode. Press and hold the pinhole reset, and press and hold PWR. Hold PWR for 3sec, release. Then release the pinhole 1 sec later. This puts the tab in APX mode. Display will be black, but PWR button is on.
Check this:
http://forum.xda-developers.com/showthread.php?t=1522384
Download the package and extract to a folder on your C drive.
Then go to Vache's site (link in the thread) and convert this number from the image you gave.
11405915515 and generate an SBK number
Connect your tab in APX mode (you should see widows show some connection when you do this about download or apx mode) if not, you will need drivers. You can always check device manager for APX mode when connected.
Run the file you downloaded as in the thread instructions. Do this through a CMD window (command window). Usually you can hold SHIFT and right mouse click and select open CMD window here.
Paste the SBK when asked (right mouse click on the curser)
Hit enter.
If it works, you get a PASS when finished.
If not, it will tell you SBK not good.
It's worth a shot anyhow.
Now I'll be gone for a couple hours. Baby needs Park in the buggy.

many thanks.
i tried but no luck, i receive a USB write error.
i tried for the second time to open a ticket at acer assistance.
first time they said they needed more info.
this time they suggested me to hard reset.
i'll try for the third time, it's annoyin i have to send the tablet and wait for i don't know how long to get it back and how much i'll pay for this (maybe 50 euros ....).
thanks for everything and have fun with your baby !

***WARNING potential brick with OTA 3.5***

If you are on OTA 3 and plan to go to OTA 3.5, make sure your recovery works first!
I attempted to install the old CWM (that didn't work with OTA3) back when I got OTA3 and had forgotten. Since it doesn't work I am stuck with my tablet bootlooping with the "Booting recovery kernel image" message. It just keeps trying to boot into recovery, thanks a lot Lenovo.
Hopefully I can fix this because I think my tablet just went out of warranty, so I can't even try to spin that. (If you know a way to force normal booting, please let me know.)
Also I should note that I have a US tablet. Which is apparently the only region with a locked bootloader. If I could get into nvflash fixing this would be a piece of cake. Now I have to stress out until I can get it fixed because I use it for taking notes in most of my classes.

Exactly same problem here. Will try to flash an update to see if it correct the problem
Hope that CWM recovery 5 works, otherwise will try to install CWMRecovery v6 (again, hope that adb works !)

Yeah, its not getting past the initial bootloader at all, so no Android, which means no ADB. Unless someone knows of a lesser-known button combo for booting into normal mode, I can't think of a way to fix this.

argh, just try to flash OTA 3 (wich should overwrite recovery) but same result ! always reboot on CWM 5.5.0.4
And adb don't seems to be recognize, so not possible to install another CWM recovery
I'm stuck !

Yeah ! solved my problem thanks to koshu (see here)
But I can do this because I had a recovery, so I don't think it will solve your problem David, try to ask Koshu, maybe he can find another way...

I shall ask him! Thanks!
