JB on A500/A501 [Working][New Links][No ICS Bootloader]

I had trouble finding a guide on how to get JB working on my a501 so I'm xposting this to xda. The link to the superuserfix was dead, but my install worked without it. I take no credit for this. Written by "dime" over at Tegra Owners.
I wanted to write a consolidated tutorial for people on the latest/unrooted 3.2.1 OTA and how to flash it to rooted Jelly Bean ROM. If you follow step 1, it actually installs an old version of Touch Recovery for you, so you do not need to bother with Acer Recovery Installer. All links are derived from the FAQ stickied thread.
1. First you need to obtain root. Follow this guide to install a rooted 3.2.1 image.
All data will be lost. The 10 step guide is included as a PDF in the download:
http://forum.xda-developers.com/showthread.php?t=1307539
Confirm you have the Superuser app installed once completed.
2. Download the following 4 zip archives, put them on your A500 external SD card, and do not extract them.
Touch Recovery: MOD EDIT: LINK REMOVED
Both latest JB ROM and GApps: MOD EDIT: LINK REMOVED.
Superuser Fix: http://www.mediafire.com/?xyznxalycnw9znw
3. Reboot your A500, and hold VOL- button until you boot into recovery.
VOL- is closest to the power button, what some would consider to be VOL+ on a phone.
Once in recovery, use VOL+/- to navigate the menu and power button to select.
4. Now that you are in recovery:
Go into the Wipe menu, and do a Data Wipe.
Go into the Install Zip from SD Card menu, and install/upgrade to the latest version of Touch Recovery.
Reboot the A500, and once again go into Recovery (hold VOL-).
Go into the Install Zip from SD Card menu, and install the JB ROM.
Go into the Wipe menu, and do a Data Wipe. (yes a 2nd data wipe)
Go into the Install Zip from SD Card menu, and install GApps.
Go into the Install Zip from SD Card menu, and install Superuser Fix.
(skip Superuser Fix if there comes a time when superuser is working by default)
Reboot the device (Don't hold VOL- this time).
5. You should now be in rooted JB.
Backup your apps with Titanium Backup or MyBackup Root.
Hope this helps.

Hi there....I'm just wondering how this works!!!!!
If I understand your guide correctly then,
U run timmydeans v4 rooted HC bootloader
check s/user
Flash 1.7.3 ics recovery, the ROM, gapps and s/user fix
Then enter recovery wipe/flash etc....
So, not only did u manage to flash a recovery, u r also running JB - all without the unlocked boot loader?????
I have to give this a go....if this really does work you have made my day, lol
Sent from my A500 using Tapatalk 2
EDIT: k I've just read 60 odd pages from the JB ROM thread - and answered my own question...seems this tegra-owners ROM runs with or without the patched boot loader....interesting!
EDIT: ok i tried this anyway even tho i was running the patched bootloader....may explain my issues!!
had troubles right from the get go - The tdv4 EUU wouldnt recognise my tab in apx mode, after mucking about I got the "Pass"
rebooted into cwm - nup - stock recovery??? weird....
found a boot.p file so renamed that and installed acer recover installer to flash cwm 1.7
from there flashed cwm 1.7.3 and the rest of the guide!!!!
could not install super user fix zip kept telling me there was an error and had aborted installation...s/user seems to be working ok
so after 7 hours I have thors JB with the 3,01 BL
perhaps it could be made clearer that this guide is for tabs runnin gingerbread or HC, altho it will work on the v8 BL the question would be why you would want to....however for those who havent updated its not as complicated as trying to get ones head around patched bootloaders, nvFlashing etc.
JUST A WARNING not all ICS/JB roms can be flashed like this MOST WILL REQUIRE the patched bootloader....
ALWAYS BACKUP and ALWAYS CHECK THE DEV's OP for whatever rom u intend to fllash, and if u dont understand something
please ask stating what rom/BL config you're on and what you're trying to flash to!!! Its alot easier than trying to talk/msg your way out of a brick

After the update did you have any issues with cellular data or is that still intact too?
Thanks!

I dont use a sim card. but on my a501 it asked me to please insert sim during first boot and always has a signal bar in the bottom right the indicates no reception. So most likely yes. Hope that helps.

For me cellular data has worked flawlessly. It has been definitely the best rom for my a501!

Thread Closed
Thread is currently closed and links removed for the following reason;
Thor202ro rom kernel violates GPL. Otherwise know as not releasing kernel source. Most people here in the forums are well aware of the fact that non-GPL compliant kernels are not allowed to have links directly posted to them. This in the XDA rules.
The reason GPL is in place, is so that things like "carrier IQ' don't happen again. This is why kernel source should be open-source. Without it, the kernel could be transmitting personal data, and nobody would know it.
Additionally, the website in question, is a revenue generating website, and thus this also violates XDA rules by having links posted to revenue generating websites (ad-fly) to download Thors software. So this is a touchy spot.
Most people know where the site is anyhow.
And no, I am not going to re-hash the history.
Any issues regarding this, then please contact XDA Senior Moderators.

But then i wanted to go back to official ISC and I updated to this:

After that my baseband turned to unknown and I tried to install this 'Changelog Final Full B928 ICS Baseband':

I replaced my previous ics recovery (6,0,1.0) with 5,0,2,7 recovery and install 'Changelog Final Full B928 ICS Baseband' from SD card. After that I can only go to recovery and my phone always restarts at white Huawei screen if I try to start it normaly.
Can anyone tell me how to go back to official GB or ICS?
How to delete or move my post? I see now that it's in wrong section of the forum :/

I tooo faced the same problem at the beginning with cm11 (cm-11-20140117-NIGHTLY-mb526) by quarx, though I was able to install cm11(cm-11-20131229-NIGHTLY-mb526) by quarx successfully.... Im a noob to this flashing stuff still managed and understood a bit of this procedure... I believe I read this some where on this forum that if you want to install ***cm11 (cm-11-20140117-NIGHTLY-mb526)*** then you need to go back to the custom rom first then from there you can install , though I'm not 100% Sure and afraid to do any experimentation with my Defy+.... As of now Im on
"Android 4.3.1"
Kernel 2.6.32.9-Aerokernel
10.2-20131030-NIGHTLY-mb526
I am facing almost the same problems as yours "Installation failed" as if there is a problem with the zip file which I'm sure of that isnt the case :/
Please somebody help the noobs...!!!
Thank you.

Try maybe installing from scratch (starting with original sbf).
I reinstalled Kitkat on my Defy+ tonight - sbf, rooted sbf, 2ndInit, cm-10-20131030, recovery update and then 140120.

Buddy Im already running cyanogenmod on my defy+ and in the second link what you gave for installing the 2ndinit Recovery it says:
DO NOT INSTALL THIS IF ARE YOU ALREADY RUNNING CYANOGENMOD. That ROM already has bootmenu pre-installed, and you'll probably end up having to flash an SBF file to recover your phone.
NOTE: You need ROOT installed on your Defy to use this application.
What should I do ???

I will try from start by using original sbf file using RSD and then CM11 and updating recovery after that Kitkat ,btw can you mention which ROM you tried because i tried these 2 earlier --> omni-4.4.2-20140117-mb526-HOMEMADE .zip and AOSPA 4.0+ PARANOIDANDROID [beta]
Kitkat 4.4.2 KOT49H android-4.4.2_r1.
Also can some1 help me with my wifi frequently disconnection problem too please .

"Half-Success :-/ ... system partition is read-only, use local.prop trick. Reboot your device and use adb to see if it run as root"

Mine sbf is rooted alredy so maybe try it first then go to CM10 .
its DEFYPLUS_U3_4.5.1-134_DFP-231_CEE_ROOTED_No_Signed.rar
downloaded it earlier from here only.

I have tried Mokee, but direct return to Quarx compilation made big stability problems too. Solution was to flash with original rom, then rooted one, 2ndInint and Quarx cm10, then cm11.
As I had Android 2.3.6 (3.4.5.1 - 231), I used these roms - http://forum.xda-developers.com/showthread.php?t=1542956.
It is very important to wipe data and cache just after first, original flash - otherwise you will have infinite boot loop and cannot run phone.
Look at http://forum.xda-developers.com/showthread.php?t=966537 too.

“Half-Success :-/ … system partition is read-only, use local.prop trick. Reboot your device and use adb to see if it runs as root”
then I restarted my phone and check with root checker and found its saying its saying Root access successful and then I wondered which I suppose I shudnt have wondered :crying: to user framaroot and do the "unroot" and again restarted , and now after restart I tried to do the regular thing wipe cache ,Dalvik , Data and the phone is not even mounting them its sayin
E: Can't mount /cache/recovery/command etc

my problem is only wifi disconnects frequently -seems on this working fine ,will check it for few days ,anyway 4.4 will still have bugs so better be on some lower version.

For the opening post: the first issue is a known bug in 4.4, I did not know it is wrong even in 4.1...

So the new Question arises what CM version is more stable or can I ask whose performance is Better in terms of speed.... As I don't mind with Features but I dont want Lags.... Previously I installed 4.2.1 I Suppose and installed the mininal gapps and was have around 240mb free of RAM...

it would've took you less time answering him than complaining.
Mate, I've had this very problem.
You need to flash an earlier version of cm. try cm10 or 10.1.
it doesnt work because you have an outdated recovery. flashing cm10 solves this.
Good luck!
edit: after you flash cm10 make sure to get the 20 oct version of cm10.2 as the 17 sept you tried to flash is not the latest

So I flashed the latest TWRP 2.8.1.0 using ADB on my 2012 N7 running the official 5.0. Read the OP to see if it was compatible and didn't see anything mentioned about it. It flashed without an issue but upon booting into recovery, I got a dead robot with the red triangle with an exclamation. Does this mean that Android 5.0 isn't supported yet? Thx in advance for the help!
Edit: Reflashed and fixed. 1st flash was probably a bad download. Thx!
Edit 2: flashed recovery.img successfully, but was stuck on boot up for 30mins. Had to reflash device back to stock to fix. Is lollipop not supported yet?

Was able to figure it out and make it work. Not sure what it was that didn't let cmd flash the recovery, but when I used the flashing recovery option in NRT, it worked like a charm.

Trying to install last TWRP recovery on dev-unlocked HTC One (M7) via fastboot.
All was ok, but cannot enter into recovery. It shows me "Entering recovery" page with HTC logo and nothing happened.
And when i tried to use .apk into Android it says "TWRP Manager has crashed".

download website seems not working either with app or by website
is there any mirror ?
thanks

Anybody having 2.8.4.1 as a flashable zip?

Install TWRP on Xperia Acro S lt26w
Hi to all. How I can Install TWRP on my Xperia Acro S lt26w. I saw ROMS for my phone with TWRP, but I cant manualy install it becouse my phone model in TWRP Manager (ROOT) from Google Play is not listed.
Sry for bad English.

So i had hurricane v12 working on my n7100 for quite some time and today i decided to flash another rom, ihad twrp 2.7 installed on my N7100, so today i updated to twrp 2.8.6 in hopes of installing another rom, and right after twrp update when i rebooted i noticed i have no signal and that my imei is corrupted, it says it's unknown. i have an old efs.img but cant restore it, tried dr.ketans solution and this one and couldnt restore the imei. do i need to have same rom installed as when i made the efs backup? becaouse im not sure if the backup i have is from when i had hurricane installed, maybe its from 4.2 version of android. Is there any help for my phone?

Leads to bootloop
Moto G XT033 with Lollipop 5.0.2
TWRP was working nice until I make a ROM backup. After finishing the backup (only saved the ROM file. Did not restore) I rebooted the system and BAN! My phone was gone!
Searching a few topics, I found more users with the same problem: uses backup feature and get a bootloop.
Watch your steps, moto G users!
