[Caution] Unlocking and Locking Bootloader - Acer Iconia Tab A100

It's been coming up more often lately, and there's something that needs to be mentioned for people who don't understand what they are doing while messing with the bootloaders.
DO NOT LOCK THE BOOTLOADER ON A CUSTOM ROM!
The process of unlocking the bootloader replaces the A100 bootloader with an A200 bootloader which responds to fastboot oem unlock, running this is fine even fully stock.
If you unlock the bootloader to install and run custom recovery (CWM, TWRP) which is then used to install a custom ROM (CM9,CM10, Flex Reaper, anything NOT Acer official). If you go and lock the bootloader again by replacing the A100 bootloader you WILL BE LOCKED OUT OF BOTH. It will prevent the use of anything other then official Acer recovery or ROM.
There is no fix for this, it needs to be sent to Acer for repair.
It can happen in a couple ways.
1. Running the lock script included with the unlock script, he mentions it will lock it, but fails to mention what will happen if it's used on custom ROM and recovery device.
2. Running the official OTA from custom recovery, it will fail to install the system, but replaces the bootloader, which locks you out of both recovery and system.
If you happen to have done 2, and catch it BEFORE rebooting or leaving recovery, you can use the unlock script to unlock the bootloader again. Once you leave recovery, you're stuck and can't get back in.
PLEASE PAY ATTENTION TO WHAT YOU ARE DOING AND LEARN WHAT THE TOOLS ARE DOING AND HOW TO USE THEM CORRECTLY!

Thanks for this Post. If I follow and use your A100 Flashing Toolkit v1.1 7-16-12 will this take a Stock A100 and Root it, Unlock the Boot Loader and Install ClockworkMod Recovery,and will the Boot Loader Remain being Unlocked ?

Yeah it stays unlocked, generally there is only the 2 ways I mentioned before, so unless you try to do it manually it shouldn't ever occur unless you try to revert to stock or flash a stock rom and having it fail.
Basically, once its unlocked don't mess with it until you need it back to stock.

Honestly, I'd bet 90%+ of all the bricks created are by people unlocking/locking the bootloader when they don't have any business doing anything. The A100 also seems to be VERY unforgiving in terms of doing ANYTHING in the wrong order when flashing.

I'd say 90% is due to emmc failure. I mean a100 wise, nit devices in general. There has been only a few reports of this scenerio happening, and its partly our fault as it is not documented anywhere in the instructions on using the unlocking script nor in my guide or anywhere else. Can't release a tool capable of bricking a device and not cover it in the instructions, however this is exactly what happened, and still hasn't been corrected, this is why I made this post.
Acer did make this very had to get back from making a mistake on, though, for sure. I really wish people would read and learn before doing this stuff, but for now all I can do is put it out there and hope its read before its to late.
Side note, not new to this stuff but flashing a boot loader still makes my brown eye pucker. Scares me beyond anything else lol.

Ok Im rooted, Boot Loader is Unlocked, Installed TWRP with the Acer Recovery Installer, made a Back Up of the Stock ICS in TWRP. On now to the CM10 Preview which I think is Great. If I restore the Stock ICS Backup I made in TWRP will that in anyway Effect the Boot Loader and Lock It Up and Brick this ?

No the backup doesn't include the boot loader so nothing to worry about there. You can also choose what you want restored or backed up.

This is What I worry about being a NewBuB with the A100. From Past Experience with TWRP it does Back Up Boot but with the Craziness of this A100's Boot Loader is what has Me Scared. Just Taken Precautions if you know what I Mean.

Boot and bootloader are different, boot is the kernel and ram disk which doesn't affect the boot loader. The boot loader calls on boot to start android. Backing up and restoring boot is recommended with the rest of the backup and restore.

It is a strange thing, but ZeroNull, the autor of the unlocked bootloader, suggested me to lock bootloader by flashing the stock ics. And everything was fine. I think, you should add to your first post that flashing honeycomb while somebody on custom rom will brick a tablet, but flshing the stock ics on a custom rom is ok. It is proved by me and some other persons from the other forum.

Not quite understanding what you are saying, flashing a stock ics on a custom rom is fine because it puts a stock rom with stock boot loader, this doesn't add anything different from what I posted.
If you mean stock ics boot loader on custom rom it will lock it out, period.
Maybe I'm just not understanding what you meant.

I mean that if somebody want to lock his bootloader he should flash the official ics in recovery and everything will be fine.But locking the bootloader by script or flashing official honeycomb wiil lead to unrecoverable tablet. Now is it clear?

From the way I understand it that would be playing with fire, I take it that one should never restore an OTA update.zip from custom recovery while running unlocked bootloader, and one should never try to lock the boot loader from custom recovery via script.. Restoring a stock ROM from recovery via nandroid backup is different than trying to flash the .zip from recovery. I'm not really sure why anyone would even want to attempt flashing an OTA update.zip from custom recovery, as the first rule of thumb when modding your device is to create a nandroid backup of your original unmodded install, so why not just restore that? Why would you want to intentionally lock the bootloader unless you have bricked the device already and wanting to send off for repair???

OK I think I get what you mean now. As Linux society mentioned above, flashing stock from cwm or twrp usually fails (as mentioned in the OP) to install system, but does install the boot loader which locks you out. Its happened before.
This post wasnt about how to lock it or whatever, it was a warning about locking it on a custom ROM and recovery and the usual mistakes made that lead to it. Locking it safely is another topic for another thread.

And this is why I said earlier that most people flashing these devices are the real problem. This is an easy device to brick compared to many. I've improperly flashed my Optimus One so many times and oft bricked it yet it is easy to recover. I have little sympathy for people that flash before reading. You have the patience of a saint pio.

aint that the truth, and then the irony of the whole thing, the one that makes the guides and provides tons of courtesy to the community ends up getting a random emmc failure that bricks his. I'd be sick keeping on with people who won't listen if it was me. all i know is everyone here should just READ pio's guides and his threads/posts from the past 2 weeks, it will serve them well and at least make them think twice before they do something off the wall, well maybe ... there is always those people who are like "I want to see what it does, that sounds cool, I want a brick" or at least it seems there are a few like that..

Htc One X brick?

Hi guys.
I flash the fullscreen mode with cmw recovery, and when the system was reebot it stop to a boot screen (white with HTC One written).
I tried to lock bootloader and installing RUU, but it say me who phone is not plug on the pc.
I tried to wipe cache/dalvik/etc etc but I'm not able to restart my phone.
Anyone can help me?
I just try to "fastboot erase cache" and "fastboot reboot-bootloader"...but nothing.
..you need to learn to make a backup in recovery first, when you dont have that much experience yet.
Which rom you was using? The stock or a custom one?
relocking bootloader and try flashing a RUU was completly overkill.
You just need the original android.policy, which was overwritten by flashing the mod you tried to get running.
I'm sure someone can provide a flashable zip for that...just ask in teh thread of the mod.
If you got your rom runnning again, esnure to make a backup in recovery. On that way you can always restore your working rom.
...and btw: brick = cant turn device on

I learn it yesterday evening, I don't forget to do it next time.
Now I'm trying to flash the RUU, before I didn't enter in fastboot.
Installing complete.........
anxiety....
...it work.
Yeah I had the same issue after installing the full screen patch too. Thankfully I'd done a Nandroid backup just after I rooted so I just did that. Would have installed a custom Rom otherwise

Hi, I'm completely new to Android and just upgraded myself from my 3GS to the One X (and what an upgrade at that!). However I'm a bit dissatisfied with the Sense interface and would like to flash it with either vanilla or some cool unofficial rom.
The problem is I'm scared to death of bricking it. Especially since a friend of mine had told me the usual method of being sure you won't get a bricked phone is to simple change the rom on your SD-card. It would seem things get a little trickier when you don't have an SD though.
How does this backup in recovery work? Will it be making a backup of everything on my phone now and place it in backup? Will this ensure a corrupt rom image or whatever won't brick my phone?
From what I understand a launch from recovery is completely separate from the rest of the system, so unless you've broken the memory card (in which case I guess your screwed anyway) it shouldn't be possible to brick the phone should it?

what you are looking to flash would be called "aosp"...android open source project, this means pure, unadulterated android from Google. At present time there are no aosp roms for the hox. They all have the HTC sense interface. Be patient. I'm sure this device will get a lot of attention from the dev community and we will have plenty of aosp roms to choose from in the near future.

You have to make sure your RUU is for the same network and country and is newer then your current RUU or the CID will block it

return to stock rom

hi, I did a trade with some here on the XDA for a galaxy nexus. The phone comes with BAMF ROM but I am thinking of returning to the completely stock rom. Since I do not know much information on this phone, I thought I will ask before doing anything stupid.
I am not sure exactly if this is a international or playstore phone (I think it is international) but I do know it is a GSM phone.
Also, it appears to me that the phone is already unlocked (and I think rooted but cannot be sure).
So my question is how exactly should I go through to get the completely stock as I kind of want to try stock JB first. Do I need to relock it and download the image from google (which image as I see there are two version of phone.
I may try different rom in the future so can I just download teh image and flash the rom without relock it? Or I should still lock the phone, flash, unnlock, unroot?
A little bit of background. I am using the phone on T Mobile's network here in the US, so I want to be able to continue using hte phone on the same T MO.
Thanks a lot for all of the helps guys.
Link to the step-by-step, amazing, descriptive guide here
thanks a lot. I follow that thread and I think I have returned the phone to the stock rom.
Quick question, I think my bootloader is still unlocked as when I checked the bootloader, it looks it still says unlocked. Now after I have flashed the stock rom, should I still root it and also install the recovery if I ever plan to play around with the different roms? As of now, when I into recovery, I see the little andrid icon but no selection.
thansk a lot guys.

If/when you want to root and mess with ROMs, you'll be using a custom recovery like CWM. You don't need to flash it until you choose to do those things.
thanks. Would I need to root again? The phone is already unlocked (as I did not lock it again). So, I would just have to root and then flash the custom recovery then?
BTW, I notice there's a very nice tool on the sticky that does everything. I am curious if I use that tool and let say choose to unlock it again or root again and such, would that be any issue? Ie, if it's already unlocked and you run unlock again, would that relock, etc?

[Q] HELP!! Have I bricked my new device!? SO WORRIED!!

Hey guys,
I'm kinda new to the HTC/Android world, found this community a damn good place to find support.. But now I've hit a road block.
Basically, I've been eager to root from day 1 of getting my first htc handset, I came across from jailbreak and loved the fact of customizability with Android.
So I had the Google play edition(I think, all geared towards Google) running Kit Kat 4.4.4. Love it, big Google user so this all tied together lovely.
Here is the Situation.
I found a video on youtube, cannot provide URL as I'm in work at the moment, but it was root guide from scratch. Fresh windows OS, seemingly a phone fresh out the box.. you get the idea.
I used the Hasoon2000 tool to root the device. Installed ADB etc on my pc, signed up as a a dev, got the Key for device, sent in and received my .bin file. I got up to actually rooting my device, well pleased and happy. Using TWRP via Hasoon2000.
But here is where **** hits the fan.
The device needed to update, It took me back to 4.4.2 but Im unsure on how to get back to most up to date OS and keep the root.
But when I reboot to install this, it goes into TWRP. no other way around this.
Queried this on another forum, decided to continue to be patient... but no replies, in the mean time I restored my apps and have a fiddle, see what the root function can do for myself.
I installed "Freedom 1.0.6" and a program called "Market Share"- Hate iAP, some games are ridiculously priced for the smallest of things, I just wanted to sandbox plague inc. ;(
Now the device is stuck in a boot loop, phone starts up, see the home screen for a bout 40 seconds/ one minute.. Some times I unlock the device and it goes back to flash screen then.. others I boot an app and its slides away once more.
This happened close to 15x before I left for work this morning and I imagine its just going to repeat this and run the battery - I tried to stop this loop by going into TWRP and possibly choosing to boot system this way may of stopped it.. but when I was on the boot screen with those options.. It said Tampered at top of screen and S-On- which has scared me quite a bit..
What the hell has happened!?
I'm desperate to know and don't want to have this damn thing bricked! Please help.. try explain like I'm 5, as said I'm new to a lot of this! >.<
first off, if the screen comes on, its not bricked.

Do you mean you accepted an official OTA? I think that is what you are saying. You should not be accepting OTAs on a phone that has been bootloader unlocked, custom recovery, etc. unless you know exactly what you are doing and what the result will be (which is clearly not the case).
Stock recovery is needed to install an OTA. That is why it keeps going to TWRP, then it doesn't find stock recovery and reboots, hence the loop you are stuck in. Try to find the OTA file and delete it.

Thank you for fast response.
Official OTA - being that the phone its self said "Update the OS" - I just accepted this, hit download and began install as a reboot- didnt spot implications. As said, noob, followed a tut. If it highlighted DO NOT UPDATE or.. IF U WANT UPDATE NOW FOLLOW THIS- Great, but nothing of the sort?
Is the OTA file basically the .exe for the OS- so find it and delete it.. although I dont have enough time to navigate and establish where the file actually is located!
Or do you have any links to tutorials I could possibly follow?
Side note- when this loop started I deleted

This is really your main issue. By following a YouTube video and using a Toolkit, you've failed to actually learn anything or gain any real understanding or knowledge. Do yourself a favor and ditch the tutorials and videos (and toolkit for that matter) and do it the old fashioned way . . . by reading. Videos and step-by-step guides do you no good when things go south (as you've now discovered). And with the prior proper knowledge (usually not gained by following tutorials) this whole mess probably would have never happened in the first place.
A cardinal rule of Android phone modding: DO NOT accept/download/install OTAs (official OS updates) on a modded device unless you know what you are doing, and what the result will be. If in any doubt, simply DO NOT do it.

.exe file is Windows specific. You are looking for a zip file, and it typically starts with "OTA". Don't remember where its saved to, so you will have to search for it. If you can't keep the phone running long enough to do so, mount the memory on your computer and search that way.
Deleting the OTA file worked for me on a past device, although one M8 user in the same position said deleting the file didn't get him out of the loop. Flashing your ROM again, or wiping the internal memory (backup any important personal data first) might be options for you.

taken on board. I know with my jailbreaks in past it has been a pain, assumed Android would be alot more stable to over write- due to functionality of OS and unlocked features.
I was being generic when I said .exe- basically the installer..
I returned from work to see phone stopped looping.. i could stop the install and deleted the file ASAP.. but now what.. Phone is still bugging me to update, lost the root(got a checker).. so whats the correct procedure!?
I am confused to what you are trying to accomplish at this point, is it to install a OTA, or a recovery? What exactly is going down here?
Me personally to take an OTA is to relock bootloader, install stock recovery, and make sure CID matches. I am S-Off so bootloader means very little, but you can unlock and relock at will when you are S-Off. You will not lose S-Off accepting an OTA.
Try to re-flash the ROM, with stok ROM, using TWRP and clean install. It should work.

First of all once the bootloader is unlocked you don't have to relock it to get OTA.
As I undersand you have done the following:
1) Unlock using HTCDev-Method
2) flashed a custom revocery (TWRP in your case)
3) flashed a supersu too!?
To install the OTA means loosing root acces. Thus you have to re-root it after the OTA is done. The other problem ist that STOCK OTAs don't work with a custom recovery. Meaning you would have to flash a stock recovery first, install the OTA second (as long as you didn't change anything an just root), and re-root third.
Let's have a look which stock recovery you would need:
1) reboot to bootloader
2) connect the phone to you PC and open cmd in you adb/fastboot folder
3) enter "fastboot getvar all"
4) paste this information here (but DELETE the IMEI and SERIAL NUMBER before posting!!)
As soon as we know which stock recovery you need we will go on.

I'm not saying there is anything "wrong" with the toolkit, per se. For the most part, it does what its intended to do.
But it also shortcuts the learning process, and facilitates folks rooting the phone without gaining the proper knowledge. This is a dangerous thing.
This is just my opinion. But I strongly believe it. If you can't accomplish these things without a toolkit, you shouldn't be rooting your phone in the first place.
Others use the toolkits, and love them. They are more than entitled to have their own opinion. But when things go south, the toolkits aren't going to help; and those folks don't have the proper knowledge and they come running here. So you tell me what is the "best" way to root the phone?

I already figured this was probably the case. But I found it better to provide the exact information on what file to delete; rather than leaving it open to the possibility of you and/or others being misinformed.

Phone is still bugging me to update, lost the root(got a checker).. so whats the correct procedure!?

Sounds like you still have TWRP installed, so just flash SU or SuperSU to gain root.
After that, you can use Titanium Backup or similar app to find the update process and freeze it, to stop the update notifications.
Don't remember the exact process (this is where searching and reading comes in for you) but its something like "drm..." or "updater".
I have this situation before,what i do is find the right stock recovery and flash..after ota done flash back custom recovery..?

At this point after seeing this, I would suggest you take some time and start reading. All of your answers are here in the forums. Knowledge is power and within the pages of this site you will find everything you need.
To take the OTA find a stock recovery, to flash ROM's find the one you like and flash via your favorite recovery.

[Q] Bumping????

Hello everyone!
I just don't get it. Can anyone explain to me what's the difference between flashing a bumped rom and flashing the same rom un-bumped? I just don't get the whole point of it! Sorry, but coming from a Nexus device (why have I ever changed!!!) I'm new to these things.
So, other questions would be: what's the point of bumping? What if I don't do it and just go about the usual way: Unlocking the bootloader, rooting and installing a custom recovery and then proceed to flash the appropriate and preferred rom, kernel, etc?
Hope somebody will bear with me and try to explain these things to a newcomer
Thanks

Because
1) Bumping is used to trick the bootloader into thinking that the boot.img is authentic and from Official LG Sources
2) Without bumping you could have to constantly run fastboot boot boot.img (an example of this was CM11 when it first started development)
3) Bootloader cant be unlocked at this time so we rely on a bootloader exploit in order to run custom recovery
4) Its all about the authenticity. If the LG bootloader does its security checks and anything fails then the system doesnt boot
Thanks for the very easy tuo understand explanation. I should have thought that the problem was unlocking the bootloader! Guess I'll have to with the Flow and bump my new phone. I wish I asked my Carrier for an HTC M8

simple answer: bump is the only way to unlock g3 bootloader.
all roms are bumped whether displaying [BUMPED] or not.

Ok, so by simple logic, once I have installed, either via bump, flashify or ADB a recovery, I can pretty much flash any rom that is appropriate for my model no, isn't it?
So there is one more question I have: what is the purpose of unlocking the bootloader and then what could be the problems if I don't? If everything I flash for this device (TWRP, roms, kernels, etc) is, by default, bumped, what's the purpose of installing bump at all?

You're making it so much harder for yourself dude.. There really is only one way to install custom ROMs and that is by Bumping your phone. That's it.
You go here and read the entire topic. Don't miss a single thing.
Then go here and flash the zip for the latest TWRP.
After that you can install any ROM in the OG and Android Development section.
That's all there is to it. You can read in those topics for more information about what they do.
if you dont bump, then you wont have twrp lol.
you cant flash any roms anyway, you'll potentially brick/soft brick your phone.
roms etc are bumped because they have a patch script implanted to run on the phones correctly.

OK. Got it! It took a while, but I give up!
Thanks for the help. Coming from the most easy to play with phones (only Nexus so far, but I hate the N6), it isn't easy to have to deal with more stuff than usually needed and hence more complications than usually had.
I thought that, after rooting I could flash TWRP via flashify or rom toolbox and then I would have TWRP without BUMP, but it must be that I'm missing something, if you say I MUST bump my phone to install TWRP.
Thanks and see you around

What exactly do you mean "How to bump"??? Bump and loki are bootloader exploits that allowed us to boot TWRP and all the benefits TWRP offers... On the user side of things you don't "Bump" anything- the Roms, Kernels, and recoveries are "pre-bumped" by the developers and 99.9% of the time they will say whether or not it is "bumped" or "lokied" although loki is really outdated and I doubt you'll encounter it. So in a nutshell we(the user) doesn't "Bump" anything and just make sure to really read before flashing

Should I unlock my bootloader for safety reasons

I've always had my devices rooted and running a custom rom or at least a custom kernel or something of the sort "But" ever since I got my pixel about a year ago I haven't felt the need to root at all, stock rom is just perfect and so battery life and I don't see a reason to.
However I was just thinking that now with locked bootloader if for any reason my phone gets bricked then I'm probably [email protected]*t out of luck because I won't be able to flash a factory image to bring the phone back to life.
Should I unlock my bootloader just in case the worse does happen or is there another workaround for such a situation?
Getting bricked is the direct result of flashing images.

I could not disagree more. There are countless threads of individuals taking OTAs and running into boot loop. Additionally I have read through multiple threads where individuals were simply using their phone to play a game, text, phone call etc and the phone shuts off and goes into a loop.
The users with an unlocked bootloader were able to salvage the device. Users without a locked bootloader looked for a RMA.
To the OP- I personally will never own an Android device with a constantly locked bootloader. The safety net of being able to factory reset and flash stock images is something I've always cherished and do not wish to get rid of.
There are security risks to having an unlocked BL. If an Android savvy criminal were to steal your device they could do a lot of damage with obtaining personal information. For me, I'm much more worried about my phone going in to boot loop than I am some criminal being able to take my phone from me.

if for any reason, something did get corrupted on your phone with a lockedbootloader and it tripped verified boot. you would be locked out, no course of action but to get an RMA... so if u plan on tinkering with your phone or just would like a failsafe, at least with an unlocked phone. you would be able to flash firmware, etc...
just remember, not to relock your bootloader; unless your phone is running stock firmware and is wiped.... otherwise you will trip verified boot and brick it...

no, it's not. getting a bricked phone is pretty much always because the person did something ill advised or dumb... like relocking their bootloader running custom firmware...
so a diect result of user error, nothing to do with flashing images.
