Acer Iconia B1-A71:

Unlock Bootloader

CWM update, that removes bloat

thx to FireDiamond

Apply the "Invalid Partition Error" fix before rooting!!!

To avoid unfixable bootloop, first apply this patch from Acer.

Install the APK, start it, click on FixG1PMT (no feedback) and uninstall afterwards. Good luck!

If you're rooting with prerooted system.img.gz here are the Downloads. Pick the one, fitting to the firmware installed on your tablet, otherwise you will get into bootloop!

FAQ

Q: I'm stuck inside a bootloop after rooting!!!11

A1: The system.img.gz you applied, wasn't suiting to the firmware version installed on your tablet. Download latest Acer firmware update ( !!! if available !!!), copy it on a micro sd card, plug it into your Iconia, go to recovery by holding Volume up and Power button while device is turned off. Then choose apply update from sd card.

A2: If you cannot apply any Acer firmware, because you always get a partition error while installing, you should do a reboot after you get the error. A user reported that this made her/his device boot into Android again, showing the new version in settings -> info. Good luck

A3: If your device is really bricked you could try bring it back to life. Here you find help: link1, link2, link3, link4 (many thanks to Gilly10, drmad and Hamza91)

A4 (B1-A71, B1-710, B1-711 only): Unbrick

A5: If the A1 - A4 didn't help. Send back the device to Acer. Tell them you tried to apply an update from sd card and ended up in this bootloop. Sending device back to Acer over UPS is free. Good luck!

Q: Successfully rooted, but still no root after rebooting!

A: Have you installed Superuser App from Google Play Store?

(B1-A71 only)Q: Cannot update, always getting ERROR: - Invalid partition setting; 17: fat 238e8000:888e8000; Instalation aborted.

A: Download "Invalid Partition Error" Patch.

(B1-A71 only)Q: I applied update from RV05RC05 to RV05RC06 but still it shows RV05RC05.

A: There is no RV05RC06. It is the RV05RC05. It got on Acers Download section with a RV05RC06 named zip file. But the content is 100% equal to RV05RC05.

Q: Toolkit fails or crashes for any reason and I don't know what to do.

A: Run it again with parameter -d, e.g.: toolkit.exe -d and post the entire output here.

Q: Root from scratch on Linux doesn't work because of Error message: 'No such file or directory bin/posix/64/adb'

A: sudo apt-get install ia32-libs libstdc++6 libgcc1 zlib1g libncurses5 libsdl1.2debian

Q: Can i flash a custom recovery?

A: No, because bootloader is locked. You would brick your tablet.

Q: Are there Custom ROMs?

A: No, see answer above.

Q: Is my data wiped during root?

A: No.

Q: Do i lose root after factory reset or wipe date?

A: No.

Q: I get an error in Engineer mode entering telnet command.

A: If Swiftkey is installed / enabled try settings Google AOSP Keyboard as default.

Q: How can I start telnet server manually?

A: Try this.
